Description

Technical Field

[0001] This utility model relates to the field of atomizing spray gun technology, and in particular to an atomizing spray gun for waste treatment. Background Technology

[0002] Waste treatment atomizing spray gun is a specialized piece of equipment used in the field of waste treatment. Its core function is to spray liquid atomized into the waste to achieve specific treatment purposes.

[0003] To avoid clogging during operation, existing atomizing spray guns for waste treatment generally adopt a large-diameter nozzle design. While this improves throughput, it sacrifices atomization effect, resulting in coarse atomized particles (typically >80μm in diameter), uneven liquid coverage, and reduced treatment efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned above in the background art by proposing an atomizing spray gun for waste treatment.

[0006] Preferably, a first convex plate is fixedly installed on the outer wall surface of the connecting pipe, and a second convex plate is fixedly installed on the outer wall surface of the filter cylinder. Both the first convex plate and the second convex plate are annular structures.

[0007] Preferably, the outer wall surface of the first convex plate has four elastic bands distributed in a ring, and the outer wall surface of the second convex plate has multiple through-band frames distributed in a ring. The ends of the four elastic bands away from the first convex plate pass through the through-band frames and are fixedly installed with fixing plates.

[0008] Preferably, an O-ring is provided between the outer wall of the filter cartridge and the inner wall of the connecting pipe, and the O-ring is made of fluororubber.

[0009] Preferably, the surface of the fixing plate is threaded with bolts, and the surface of the first convex plate is circumferentially distributed with multiple internally threaded sleeves. The bolts pass through the threaded holes of the fixing plate and are screwed into the internally threaded sleeves for fixation.

[0010] The effects achieved by the above components are as follows: through the dual filtration structure of the filter screen and the PP material filter element, it can effectively intercept solid particles and colloidal substances in landfill leachate, avoid nozzle clogging, and through the plug-in filter cartridge with the quick disassembly and assembly structure of elastic band and bolt, the filter element replacement time is shortened and the maintenance efficiency is improved.

[0011] Preferably, an atomizing device is fixedly installed on the end surface of the barrel away from the gas interface. The atomizing device includes a hollow shell fixedly installed on the end surface of the barrel away from the gas interface. Multiple spiral guide vanes are distributed in a ring inside the hollow shell. A conical part is fixedly installed on the end of the spiral guide vane away from the hollow shell. A nozzle is fixedly installed on the surface of the conical part.

[0012] Preferably, the conical part is a hollow cone structure with a cone angle of 60 degrees, and its internal channel is connected to the inner cavity of the hollow shell.

[0013] Preferably, the spiral directions of adjacent spiral guide vanes are consistent to form a gas-liquid vortex rotating in the same direction.

[0014] The effect achieved by the above components is that by combining the spiral guide vane with the conical part with a cone angle of 60 degrees, atomized particles with an average particle size of 25-30μm can be generated under gas pressure, thereby increasing the coverage area.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting up a filtration device, the dual filtration structure of the filter screen and the PP material filter element can effectively intercept solid particles and colloidal substances in landfill leachate, avoiding nozzle clogging. Furthermore, the quick-disassembly and assembly structure of the plug-in filter cartridge with elastic band and bolts shortens the filter element replacement time and improves maintenance efficiency.

An O-ring 212 is provided between the outer wall of the filter cylinder 201 and the inner wall of the connecting pipe 7. The O-ring 212 is made of fluororubber. Bolts 210 are threadedly connected to the surface of the fixing plate 209. Multiple internally threaded sleeves 211 are distributed in a ring on the surface of the first convex plate 205.

[0025] Reference Figure 1-2As shown in this embodiment: an atomizing device 3 is fixedly installed on the surface of the barrel 1 away from the gas interface 5. The atomizing device 3 includes a hollow shell 31 fixedly installed on the surface of the barrel 1 away from the gas interface 5. Multiple spiral guide vanes 32 are annularly distributed inside the hollow shell 31. A conical portion 33 is fixedly installed on the end of the spiral guide vane 32 away from the hollow shell 31. A nozzle 34 is fixedly installed on the surface of the conical portion 33. The conical portion 33 is a hollow cone structure with a cone angle of 60 degrees. Its internal channel communicates with the inner cavity of the hollow shell 31. Adjacent spiral guide vanes 32... The spiral directions of the spiral guide vanes 32 are consistent to form a gas-liquid vortex rotating in the same direction. The blade thickness of the spiral guide vane 32 is 1-1.5 mm, and the angle between the blade and the inner wall of the hollow shell 31 is 30 to 45 degrees. The spiral directions of adjacent spiral guide vanes 32 are consistent to form a gas-liquid vortex rotating in the same direction. The conical part 33 is a hollow conical structure with a cone angle of 60 degrees. Its internal channel is connected to the inner cavity of the hollow shell 31, and the channel diameter gradually decreases from 8 mm at the inlet end to 3 mm at the outlet end. The pitch of each spiral guide vane 32 is 12 mm, and the orifice diameter of the nozzle 34 is 0.3 mm.

[0026] Working principle: When the device is needed, first insert the filter cartridge 201 axially along the connecting pipe 7, so that the first convex plate 205 and the second convex plate 206 fit tightly together. Pass the four rubber elastic bands 207 through the corresponding strap frames 208 respectively. Pull the elastic bands 207 to press the fixing plate 209 onto the surface of the second convex plate 206. Use an M6 wrench to screw the bolts 210 into the internal threaded sleeve 211, and control the tightening torque at 8-10 N·m to complete the installation of the filter device 2. Then connect the gas interface 5 to the 0.6MPa compressed air source through the G1 / 4 thread. Finally, connect the liquid inlet 204 to the landfill leachate storage tank through the acid and alkali resistant hose. After all assembly is complete, pull trigger 6 to activate the solenoid valve and open the compressed air passage. The gas enters the hollow shell 31 through the gun barrel 1, and the leachate enters the filter cartridge 201 through the inlet 204. It first passes through the 50μm stainless steel filter screen 202 to intercept larger particles, and then passes through the PP filter element 203 to adsorb colloidal substances. The filtered liquid enters the gun barrel 1. The gas-liquid mixture is generated into a high-speed rotating vortex in the hollow shell 31 by the action of the spiral guide vane 32. After being accelerated by the cone-shaped part 33 with a cone angle of 60 degrees, it is sprayed out through the 0.3mm nozzle 34, thereby adjusting the moisture content of the garbage to 50%-60%, optimizing the anaerobic fermentation environment, promoting garbage degradation, and suppressing dust.
