An automatic pellet loader of a pneumatic air gun, including a pellet clip seat, a pellet clip lid, a pellet clip closure, and a magnetic shaft. The pellet clip seat and the pellet clip lid are connected to form a magazine case that includes a pellet inlet. The pellet clip closure is rotatably connected to the magazine case for opening or closing the pellet inlet. The bottom side wall of the pellet clip seat is provided with a loading sleeve that extends to the pellet clip lid. A center hole of the loading sleeve perpendicularly penetrates through the pellet clip seat. The pellet clip lid includes a loading channel allowing the pull-bolt thimble to pass through. The loading sleeve includes an opening close to an exit side of the loading channel through which a single pellet can slip autonomously into the loading channel.

Single pellets of a thermoplastic resin containing long glass fibers and a conductive filler are set forth that enable molded articles made from these pellets to exhibit conductivity and, at the same time, high mechanical properties. These pellets have mechanical properties that are substantially equivalent to non-conductive pellets of a thermoplastic resin containing same loading of long glass and provide conductivity that is substantially equivalent to articles obtained by blending two kinds of pellets, one pellet having a conductive filler and the other pellet one containing long glass fibers. The pellets include a thermoplastic resin, a long fiber reinforcing filler and a conductive additive dispersed in the pellet.

A fuel rod loading system includes a plurality of pellet loading stations each designated to load a single pellet type into one or more pellet bores of the pellet magazine, a rod loading station configured to unload pellets from the pellet bores of the pellet magazine into a fuel rod, and a conveyance system configured to transport the pellet magazine to the loading stations and then to the rod loading station in a defined sequence.

The invention discloses a breeding method of a single-grain beet high-resistance pairing sterile line. The method comprises the steps of selecting high-resistance and single-grain beet base material, and carrying out summer seeding to cultivate a mother root; carrying out spatial isolation planting, inspecting the grain fertility of all single plants, separating single-grain sterile plants from single-grain fertile plants, and respectively listing to obtain seeds of the sterile plants and corresponding seeds of the fertile plants; carrying out centralized isolated hybridization on plant pairs, and harvesting to obtain first-filial generation F1 strain seeds; carrying out backcross selection by a backcross transformation method, and selecting the strain material with the single fertility rate higher than 95% in the sterile line; indentifying and selecting the cultivated single-grain paired male sterile material on a beet spring sowing disease garden land or a beet seed collecting disease garden land; carrying out disease resistance screening, selecting and remaining the plants with resistance, and harvesting the seeds in pairs. Compared with the prior art, the breeding method has the beneficial effects that the single-grain sterile line with high purity can be cultivated, the single grain rate reaches 99%, and the sterility rate reaches 95%. After being indentified, selected and cultivated on the disease garden land for a plurality of years, the single-grain beet pairing sterile line is high in resistance.

The present invention discloses a fly ash raw material pellet production method, which comprises: 1) a mixing step, wherein coal powder coal and ammonium sulfate are mixed according to a predetermined ratio to obtain a raw material; 2) a pellet pressing step, wherein the raw material is pressed into a raw material pellet; 3) a screening step, wherein the complete pellet is conveyed into a sintering kiln system through screening, and the broken pellet is conveyed to the step 1); and 4) a re-pressing step, wherein the conveyed broken pellet and the raw material are mixed and are re-pressed into the pellet. According to the present invention, the raw material obtained by mixing the fly ash and the ammonium sulfate can be prepared into the raw material pellet, and the raw material pellet does not contain water and any other adhesives so as to effectively achieve energy saving and consumption reduction; and the physical performances of the raw material pellet produced by adopting the process can achieve the following parameters, wherein the single pellet density is 1.3-1.6 g / mm<3>, the pellet bulk density is 800-1000 kg / m<3>, the pellet initial strength is 400-650 N, and the pellet strength after heating is 1200-1500 N, such that the performances can completely meet production requirements of the sintering kiln.

The invention discloses a ferroferric oxide ceramsite and its preparation method and application. The preparation method of the ferroferric oxide ceramsite includes the following steps: step 1, weighing four Ferric oxide powder and bentonite, then add 0.4-0.6% NaHCO of the total mass of the two 3 , mix well, add water and mix thoroughly; step 2, use the pelletizing machine to make the mixture obtained in step 1 into a single pellet with a diameter of 5-10mm; step 3, dry the pellet prepared in step 2 at 120-180°C 20-40 minutes; step 4, seal the dried pellets, bake at 150-250°C for 20-40 minutes, then cool naturally to room temperature 20-30°C to obtain ferric oxide ceramsite. The ferroferric oxide ceramsite can be used as a microwave-absorbing material to inactivate biological aerosols by microwave radiation.

A durable carbon pyrolyzate adsorbent having reversible sorptive affinity for hydrogen sulfide, and including the following characteristics: (a) a bulk density as measured by ASTM D2854 in a range of from 0.55 g / cc adsorbent to 1.25 g / cc adsorbent; (b) an H2S capacity in a range of from 140 cc H2S / g adsorbent to 250 cc H2S / g adsorbent, at normal conditions (1 atm, 293.15° K); (c) an H2S capacity in a range of from 1.0 cc H2S / g adsorbent to 15.0 cc H2S / g adsorbent, at partial pressure of 0.76 torr (101.3 Pa) (1000 ppm) of H2S at 293.15° K; and (d) a single pellet radial crush strength in a range of from 7 kilopond (kP) to 40 kilopond (kP) as measured by ASTM D4179. Such adsorbent is usefully employed for capture of hydrogen sulfide from gases containing same, such as H2S-containing gas associated with flowable hydrocarbonaceous material in refining operations, biogas produced by biomass digesters, gas mixtures produced by fluid catalytic cracking (FCC) units, and effluents from power plants gasifying sulfur-containing coal in an integrated gasification combined cycle (IGCC) process.

The invention discloses a recycling process for low-frequency (LF) furnace refining slag. The process is characterized in that the process comprises the following steps of: mixing LF furnace slag with the weight percentage of 10-30 percent with iron-containing waste materials with the weight percentage of 70-90 percent; controlling moisture content of the mixed material to be 13-18 percent; putting the mixed material into a mixing mill for mixing and milling according to the proportion for 20-30 minutes to uniformly mix; compacting and forming the mixture by a cold press forming machine; and naturally placing for 25-30 days to form metallurgy cold-pressed pellets. The process has the effects that for the pellets prepared by the method, the compression strength of a single pellet can reach over 2500N, a one-meter free drop test can be performed more than twenty times to completely meet a requirement of the strength of the metallurgy cold-pressed pellets, and the pellets can be applied to blast furnaces or converters. The process provides a new path for recycling LF furnace refining slag. A binder is not needed to add, the LF furnace refining slag is used, and the high-strength pellets are compressed, so that a direction for the recycling metallurgy iron-containing waste materials is provided, and the production cost of the cold-pressed pellets is reduced.
