The invention relates to a heat dissipation type switch cabinet, in particular to a heat dissipation type switch cabinet with a sweeping function. Heat can be dissipated at any time when a switch cabinet works, and the inside of the switch cabinet can be swept. The heat dissipation type switch cabinet with the sweeping function comprises the switch cabinet and the like. Switch mechanisms are arranged at the front of the switch cabinet, a mounting frame is connected with the inner top of the switch cabinet, a heat dissipation and sweeping mechanism is arranged in the mounting frame, and a sweeping strip is connected onto the heat dissipation and sweeping mechanism. The heat dissipation type switch cabinet has the advantages that the heat can be dissipated at any time when the switch cabinetworks, and the inside of the switch cabinet can be swept; the heat dissipation type switch cabinet is provided with the heat dissipation and sweeping mechanism, dust on the inner periphery of the switch cabinet can be swept by the sweeping strip, the heat can be dissipated for the switch cabinet by a blade, and accordingly effects of sweeping the switch cabinet and dissipating the heat can be realized.

The invention discloses a method and device for recovering residual powder on metal additive manufacturing substrates, comprising a sealed chamber, a pneumatic vibrator arranged outside the sealed chamber, and a vibrating clamp arranged on the inner wall of the sealed chamber for transmitting vibration Components, the vibrating clamping component is connected with a pneumatic vibrator, and the vibrating clamping component is used to clamp the substrate of the molded part and provide mechanical vibration to the substrate; the sealed chamber is provided with a high-pressure air gun and an inert gas inlet. The method and device can not only thoroughly remove the residual powder on the substrate, but also recycle the powder that has been sieved out of impurities, saving materials; since the entire recovery process is carried out under the protection of an inert gas, it can also prevent the powder from being oxidized and Moisture, to ensure that the original quality of the powder remains unchanged.

The invention provides a back flush filter, relating to the field of sewage purification treatment facilities. The back flush filter comprises a shell, an electrodynamic mechanism, a coarse screen, a fine screen, a sewage suction device and a gas supply unit, wherein the coarse screen and fine screen are arranged in the cavity of the shell; the coarse screen and fine screen are respectively cylindrical, and form a back flush chamber with the inner wall of the shell; one end of the shell is provided with a sewage inlet; the upper end of the shell is provided with the electrodynamic mechanism and a purified water outlet; the lower end of the shell is provided with a drainage port; the sewage suction device comprises a drainage pipe, a high-pressure gas pipe, a sewage suction pipe and an exhaust pipe; the high-pressure gas pipe is sheathed in the drainage pipe; the sewage suction pipe communicates with the inner cavity of the drainage pipe; the exhaust pipe penetrates through the wall of the drainage pipe and communicates with the inner cavity of the high-pressure gas pipe; the exhaust pipe comprises a straight-opening pipe and a bent-opening pipe; and the gas supply unit comprises a motor, a gas pump and a gas supply pipe. The back flush filter has the advantages of high cleaning efficiency and thorough cleaning, and can satisfy the quality requirements for sewage filtration and automatic drainage.

The invention discloses a processing device for deeply purifying high-concentration desorption liquid of waste water resin. The processing device includes an annular pool wall and a stirring pool, the stirring pool is installed in the annular pool wall, and a stirring device is arranged in the stirring pool , the space formed between the stirring pool and the annular pool wall is a treatment pool, and several collection pools are arranged in the treatment pool, and the collection pools are respectively installed on both sides of the stirring pool, and the lower ends of the collection pools are respectively provided with filter materials Layer, the bottom of the treatment pool is provided with a mud scraping device. The structure design of the invention is reasonable, which can not only overcome the relatively low secondary utilization rate of the desorbent during the treatment of the current high-concentration desorption liquid, and the wastewater treatment effect is difficult to meet the requirements, but also can effectively improve the utilization of the desorbent The efficiency can effectively ensure the treatment effect of waste water. In the present invention, a cleaning device is also designed, which can fully clean the device and has extremely high practicability.

The invention discloses a household sewer pipeline claw-type rapid guiding and dredging device, which comprises a feeding air guide pipe, a micro air pump and a dredging piece, one end of the feedingair guide pipe is of a closed structure, a connecting shaft sleeve is arranged at the other end of the feeding air guide pipe, the dredging piece comprises an extension air guide pipe and a sphericalair bag, one end of the extension air guide pipe communicates with the connecting shaft sleeve, the air inlet end of the spherical air bag communicates with the other end of the extension air guide pipe, the outer surface of the spherical air bag is provided with a friction piece for brushing the inner wall of a sewer pipeline, a shifting piece used for pulling the spherical air bag is further arranged at the end, close to the connecting shaft sleeve, of the feeding air guide pipe, a hooking piece used for hooking blockage in the sewer pipeline is hinged to the outer surface of the extension air guide pipe, and the output end of the micro air pump communicates with the end, away from the connecting shaft sleeve, of the feeding air guide pipe. On the premise that the pipeline is not damaged, dirt or blocked foreign matters in the sewer pipeline can be fully cleaned, and great convenience is brought to daily life of people.
