The invention discloses an airbag type stab columnar pipe cleaner capable of dissolving water pressure and automatically rotating. The airbag type stab columnar pipe cleaner comprises a column body, wherein the column body is provided with a conical head part; three groups of rotary flow guiding plates are arranged on the outer wall of the column body and are equidistantly distributed along the circumferential direction of the column body at intervals; a pressure-proof airbag is arranged in an inner cavity of the column body; steel brushes are arranged on the flow guiding plates; each steel brush comprises a plurality of groups of comb teeth which are arranged in parallel; the comb teeth are firmly embedded in the flow guiding plates by steel nails or adhered to the flow guiding plates by steel wires; the flow guiding plates are fixed with the column body in an embedded way; the pressure-proof airbag adopts a sealed structure; the range of external pressure borne by the pressure-proof airbag is 0.6-1.0MPa; the column body is made of a high-strength polyurethane foam material; a polyurethane elastic material coating layer is paved on the surface of the column body. According to the airbag type columnar pipe cleaner disclosed by the invention, automatic rotation forwarding and steel brush cleaning of the pipe cleaner in a pipe through water flow pressure are realized, the pipe cleaner is enabled to successfully pass through a blocking point by an airbag type structure, higher hardness and higher strength are ensured by a steel nail type steel brush, and efficient cleaning on long, short and complicated pipelines can be realized.

The invention relates to the technical field of garbage treatment, and discloses a crushing device for domestic garbage solid waste treatment, which includes a crusher body, a heating boiler is arranged inside the crusher body, and an electric heating tube is arranged at the bottom of the heating boiler. A water outlet pipe is installed at the bottom of the crusher body, a water outlet valve is installed on the body of the water outlet pipe, a top cover is installed on the top of the heating boiler, and a rotating shaft is installed on the left side of the top cover. A screw hand valve is installed on the top of the top cover. The crushing device for solid waste treatment of domestic garbage, through the setting of the heating boiler, pressing film, metal pressing plate and impact hammer, when the pressure in the heating boiler increases to squeeze the pressing film and the metal pressing plate moves inward, for the beer bottle in the pressing film Squeeze and crush. Compared with blade crushing, this crushing method can control the noise well. During the process, only when the beer bottle is broken, there will be noise, and the machine will produce almost no noise.

The invention relates to the technical fields of oil and gas drilling, well completion, well cementing or well logging, and in particular to a casing outer packer, which includes a central pipe, a rubber sleeve and a rubber sleeve fixing ring, and the rubber sleeve is sleeved outside the central pipe. The rubber cartridge fixing ring is fixed on the central tube and is fixedly connected with both ends of the rubber cartridge. There is an annular space between the rubber cartridge and the central pipe. The outer cylinder is made of oil-expanded elastic material. The rubber cylinder fixing ring is provided with a first flow channel leading to the annular space. The inlet of the first flow channel is provided with a sealing valve core. A radial through hole is arranged in the center, and a fractable sealing film is arranged at the end of the through hole facing the central tube, and finger reeds are arranged around the joint of the rubber cartridge and the rubber cartridge fixing ring. The casing outer packer provided by the invention can avoid the bursting, tearing and extrusion of the rubber tube, and improve the sealing effect.

The invention relates to a defoaming device for stripping developing solution KOH / NaOH. An air drafting pipe and a plurality of liquid medicine spraying parts are arranged above a substrate transmission box; a transmission idler pulley is arranged below the substrate transmission box; a net-shaped heating pipe is arranged below the transmission idler pulley; net-shaped defoaming cotton is arranged on the lower surface of the heating pipe; a liquid medicine draining port is arranged at the bottom of the box body; channel openings for connecting a previous process and a following process and transmitting a glass substrate are arranged on two sides of the substrate transmission box; a liquid medicine reflowing port on a liquid medicine groove is positioned below a liquid medicine level; a new liquid medicine spraying part is arranged above the liquid medicine in the liquid medicine groove; the liquid medicine draining port is connected with the liquid medicine groove by a pipeline; a liquid outlet of the liquid medicine groove is connected with a spraying pump by the pipeline; and a liquid supplying pipeline is connected with the spraying parts of the substrate transmission box, so that a complete liquid supplying system is formed. By adopting the defoaming device, most of foams produced in a production pprocess can be removed, cooperation is brought to a production technology, and the liquid medicine is prevented from polluting, so that normal production can be ensured, and quality of products can be improved.

The invention provides a coating operation system for the production of lithium batteries, including a base plate, a side plate, an outer cylinder box, a coating unit, a diversion unit, an internal stirring mechanism and an auxiliary mechanism; the invention can solve the problem of existing Due to the large amount of air bubbles in the stirred slurry during the coating process of the pole piece, the air bubbles inside the slurry are sprayed on the pole piece during the coating process. When the pole piece is dried in an oven, the bubbles burst and a white round spot is formed on the pole piece. The active material coating here is relatively thin, and micro-short circuit is most likely to be caused during the charging and discharging process of the battery; at the same time, the current electrode sheet is restricted by the flow rate of the slurry during the coating process, resulting in poor slurry coating on the electrode sheet. Uniformity, after the active material particles at the thick side are crushed, the transmission path of lithium ions and electrons becomes farther during the charging and discharging process, which will lead to increased internal resistance of the battery and deepened polarization, which will affect the service life and safety of the battery. .
