Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an explosion-proof powder spraying dust collector. Background Technique

[0002] A powder spraying dust collector is a device specifically designed to capture and process the dust and waste gas generated during the powder spraying process, mainly used to protect the environment, improve product quality and employee health. The main working principle of the powder spraying dust collector is to inhale or extract the dust and waste gas generated during the powder spraying process, and then use an efficient filtration system to capture it and then discharge it. The filtration system can effectively capture dust and particulate matter of different particle sizes. At the same time, the dust collector is made of explosion-proof materials, improving the safety of the dust collector during collection, and the filtration system can be disassembled and cleaned.

[0003] The patent document CN206046237U discloses a plant powder classification collector, which discloses "including a powder-air flow mixing conduit connected to the powder outlet of a high-speed pulverizer and a breathable cloth bag. The other end of the powder-air flow mixing conduit is connected to a primary powder collection tank, and the top of the primary powder collection tank is connected to a secondary powder collection tank through a primary cyclone air outlet pipe; a secondary cyclone air outlet pipe is fixedly connected to the top of the secondary powder collection tank, and the top end of the secondary cyclone air outlet pipe is connected to a group of dust collection bags arranged in a wooden-shaped balanced layout; breathable cloth bags are respectively connected to the bottoms of the primary powder collection tank and the secondary powder collection tank; this device not only overcomes dust flying, avoids powder coking, but also can effectively prevent dust explosion and fire, and is a safe and practical pulverizing mechanical device".

[0004] However, the plant powder classification collector in the above-mentioned published literature mainly considers effectively preventing dust explosion and fire, and is a safe and practical pulverizing mechanical device, but it is not convenient to clean the dust adsorbed on the dust net. When too much dust accumulates on the dust net, it will affect the flow of gas and thus affect the normal operation of the dust collector. When cleaning the dust net in the prior art, the dust net often needs to be disassembled, and frequent disassembly will cause damage to the connecting bolts on the dust net.

[0005] In view of this, it is necessary to research and develop a cleaning mechanism, which can clean the dust adsorbed on the dust net. Content of the Utility Model

[0006] The purpose of the utility model is to provide an explosion-proof powder spraying dust collector to solve the technical problem of enabling the explosion-proof powder spraying dust collector to have a cleaning function as mentioned in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solution: an explosion-proof powder spraying dust collector, comprising: a dust collecting shell, a dust net is installed on the inner wall of the dust collecting shell, an activated carbon plate is installed on the inner wall of the dust collecting shell, and a cleaning mechanism is provided on the inner wall of the dust collecting shell, and the cleaning mechanism is used to clean the dust adsorbed on the dust net;

[0008] The cleaning mechanism includes a scraping rod, which is arranged on the outer wall of the dust collecting shell, a scraping plate is installed at the output end of the scraping rod, a scraping groove is provided on the inner wall of the dust collecting shell, an adsorption groove is provided on the inner wall of the dust collecting shell, a closed rod is installed on the inner wall of the dust collecting shell, a closed plate is installed on the output end of the closed rod, an adsorption box is installed on the outer wall of the dust collecting shell, an adsorption fan is installed on the inner wall of the adsorption box, air holes are provided on the inner wall of the adsorption box, a protective net is installed on the inner wall of the adsorption box, a discharge groove is provided on the bottom of the adsorption box, a knocking motor is installed on the inner wall of the dust collecting shell, and a spring bump is installed on the output end of the knocking motor.

[0009] Preferably, a dust collecting pipeline is installed on the outer wall of the dust collecting shell, a dust collecting fan is installed on the outer wall of the dust collecting pipeline, an inspection door is provided on the outer wall of the dust collecting shell, and an exhaust hole is provided on the inner wall of the dust collecting shell.

[0010] Preferably, a detection mechanism is provided on the outer wall of the dust collecting shell, and the detection mechanism is used to perform dust detection on the filtered gas to observe whether the gas meets the emission standards.

[0011] Preferably, the detection mechanism comprises a dust inspection box, and the dust inspection box is arranged on the outer wall of the dust collecting shell.

[0012] Preferably, a dust instrument panel is installed on the top of the dust inspection box, and a dust concentration measuring instrument is installed on the inner wall of the dust inspection box.

[0013] Preferably, the inner wall of the dust inspection box is provided with a standard through hole, and the inner wall of the standard through hole is installed with a first solenoid valve.

[0014] Preferably, the inner wall of the dust inspection box is provided with a secondary processing through hole, the inner wall of the secondary processing through hole is installed with a second solenoid valve, and the outer wall of the dust inspection box is installed with a connecting pipeline.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is equipped with a cleaning mechanism to clean the dust adsorbed on the dust net. When the dust net is heavily accumulated, it will affect the circulation of gas and affect the normal operation of the dust collector. When the existing dust net is cleaned, the dust net often needs to be disassembled, and frequent disassembly will cause the connecting bolts of the dust net to be damaged. Therefore, it is necessary to facilitate the cleaning of the dust adsorbed on the dust net. First, the knocking motor drives the spring protrusion to rotate, so that the spring protrusion knocks the dust net, and then the scraping pole drives the scraping plate to move out of the scraping groove to scrape and clean the dust adsorbed on the dust net. Then, the closing pole drives the closing dense plate to move, so that the adsorption groove is circulated, and the scraped waste residue is pushed into one side of the protective net in the adsorption electric box. At the same time, the adsorption fan is used to adsorb the floating dust into the adsorption electric box, and then the discharge chute is used to discharge the waste residue, so as to facilitate the cleaning of the dust adsorbed on the dust net.

[0017] 2. The utility model is equipped with a detection mechanism to detect dust on the filtered gas to observe whether the gas meets the emission standards. After filtering the gas, it is impossible to know whether the gas has been filtered and meets the standards, so it is necessary to improve this so that the dust collecting shell has a gas detection function. When the gas is discharged from the exhaust hole into the dust inspection box, the dust concentration meter then detects the dust in the gas and feeds back the dust amount through the dust instrument panel. If the standard is met, the first solenoid valve works to allow the standard through hole to flow and discharge the gas. If the standard is not met, the second solenoid valve works to allow the secondary treatment through hole to flow, and the connecting pipeline is used to circulate the gas to the external collection box for secondary filtration, so that the standard gas can be discharged to protect the external environment.

[0029] See also Figure 2 and Figure 5The outer wall of the dust collecting shell 1 is provided with a detection mechanism, which is used to detect dust on the filtered gas to observe whether the gas meets the emission standard. The detection mechanism includes a dust inspection box 20, which is arranged on the outer wall of the dust collecting shell 1, and a dust instrument panel 21 is installed on the top of the dust inspection box 20. A dust concentration measuring instrument 22 is installed on the inner wall of the dust inspection box 20.

A secondary processing through hole 25 is provided on the inner wall of the dust inspection box 20, and a second solenoid valve 26 is installed on the inner wall of the secondary processing through hole 25. A connecting pipeline 27 is installed on the outer wall of the dust inspection box 20 After filtering the gas, it is impossible to know whether the gas has been filtered and meets the standards, so it is necessary to improve this so that the dust collecting shell 1 has a gas detection function. When the gas is discharged from the exhaust hole 28 into the dust inspection box 20, the dust concentration measuring instrument 22 then detects the dust in the gas and feeds back the dust amount through the dust instrument panel 21.

[0030] The working principle is that the dust and exhaust gas generated during the powder spraying process are adsorbed into the dust collecting shell 1 through the dust collecting pipeline 2 by using the dust collecting fan 3, and then the dust is filtered and adsorbed by the dust net 4, and at the same time, the activated carbon plate 5 filters the exhaust gas in the air, and the filtered gas is discharged through the exhaust hole 28. The inspection door 19 is used to disassemble the dust net 4 and the activated carbon plate 5.

When the dust net 4 is cleaned, it is often necessary to disassemble the dust net 4, and frequent disassembly will cause the connecting bolts on the dust net 4 to be damaged. Therefore, it is necessary to facilitate the cleaning of the dust adsorbed on the dust net 4. First, the knocking motor 17 works to drive the spring protrusion 18 to rotate, so that the spring protrusion 18 knocks the dust net 4, and then the scraping pole 6 works to drive the scraping plate 7 to move out of the scraping groove 8 to scrape and clean the dust adsorbed on the dust net 4, and then the closing pole 10 works to drive the closing plate 11 moves to make the adsorption groove 9 flow, and the scraped waste residue is pushed into the side of the protective net 15 in the adsorption electrical box 12. At the same time, the adsorption fan 13 is used to adsorb the floating dust into the adsorption electrical box 12, and then the discharge groove 16 is used to discharge the waste residue, so as to facilitate the cleaning of the dust adsorbed on the dust net 4. After filtering the gas, it is impossible to know whether the gas is filtered and meets the standards, so it is necessary to improve this so that the dust collecting shell 1 has a gas detection function. When the gas is discharged from the exhaust hole 28 into the dust inspection box 20, the dust concentration measuring instrument 22 then detects the dust in the gas and feeds back the dust amount through the dust instrument panel 21. If the standard is met, the first solenoid valve 24 works to make the standard through hole 23 flow to discharge the gas. If the standard is not met, the second solenoid valve 26 works to make the secondary treatment through hole 25 flow, and the connecting pipe 27 is used to circulate the gas to the external collection box for secondary filtration, so that the qualified gas can be discharged to protect the external environment.
