Description

Technical Field

[0001] The utility model relates to the technical field of dust collecting devices, in particular to a dust collecting device with a pulse electromagnetic valve. Background Art

[0002] The new energy die-cutting process involves a cutting process, which will generate cuttings and dust when cutting materials. In order to protect the processing environment and the health of workers, a dust suction device is required to absorb the cuttings and dust generated by the cutting.

[0003] When the existing dust collection device is in use, dust will gradually adhere to the outer surface of the filter cartridge. When the dust accumulates to a certain thickness, it will affect the flow of air, resulting in a decrease in suction force and affecting the dust collection effect. Moreover, if the filter cartridge is frequently removed for cleaning, not only will the workload increase, but the equipment shutdown will also have a significant impact on production capacity, which is not conducive to the company's production and operation. Utility Model Content

[0004] The utility model aims to provide a dust collecting device with a pulse electromagnetic valve which can clean dust without removing a filter cartridge.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A dust collecting device with a pulse electromagnetic valve comprises a body, a fan is installed on the top of the body, an air outlet pipe is arranged on the upper surface of the body, an air inlet pipe is arranged on the side surface of the body near the bottom, a partition plate is installed inside the body, four through holes are opened on the surface of the partition plate, four filter cartridges are installed on the lower surface of the partition plate, and the four filter cartridges correspond to the four through holes one by one. A diverter bottle is installed on the upper surface of the partition plate, the diverter bottle is connected to an external air source, L-shaped nozzles are connected to the outer surfaces of both sides of the diverter bottle, and the ends of the L-shaped nozzles correspond to the center of the filter cartridge, and a pulse electromagnetic valve is arranged on the outer surface of the L-shaped nozzle.

[0007] It can be seen that the air inlet pipe is connected with the dust suction pipe, and suction is generated by the fan and acts on the end of the dust suction pipe to achieve the purpose of dust suction. When a large amount of dust adheres to the outer surface of the filter cartridge, which causes the suction force to decrease and affects the dust suction effect, the pulse solenoid valve can be started. When the gas speed passing through the L-shaped nozzle is very high and the time is very short, the gas ejected from the end of the L-shaped nozzle has a large kinetic energy, which can blow off the dust attached to the outer surface of the filter cartridge, thereby achieving the purpose of self-cleaning. There is no need to remove the filter cartridge, which ensures the normal operation of production and is beneficial to the production and operation of the enterprise.

[0008] Furthermore, a dust collecting box is installed at the bottom of the machine body through a slide rail, the dust collecting box is located directly below the filter cartridge, and an inspection door is provided at a position on the outer surface of the machine body corresponding to the dust collecting box.

[0009] The dust blown off the filter cartridge falls into the dust box. When the dust in the dust box is collected to a certain extent, the inspection door can be opened to pull the dust box out for cleaning.

[0010] Furthermore, a pair of differential pressure sensors are installed on the inner wall of the machine body, and the two differential pressure sensors are respectively arranged on the upper and lower sides of the partition plate.

[0011] The differential pressure sensor is used to detect the internal and external pressure difference of the filter cartridge. The larger the pressure difference, the more serious the filter cartridge blockage. By observing the size of the pressure difference, it is easy to help workers understand the use of the filter cartridge and facilitate timely cleaning.

[0012] Furthermore, an observation window is provided on the outer surface of the body at a position corresponding to the diversion bottle, and the material of the observation window is tempered glass.

[0013] The differential pressure sensor can only respond to the internal and external pressure difference of the filter cartridge. When three of the filter cartridges are cleaned and one of them is not cleaned, the detected differential pressure is usually a normal value. Therefore, by setting up an observation window, workers can observe the use of the filter cartridge and the pulse solenoid valve from the outside to avoid the situation where a pulse solenoid valve is damaged and the filter cartridge cannot be purged.

[0014] Furthermore, an activated carbon filter is installed at the end of the air outlet pipe, and the activated carbon filter and the air outlet pipe are threadedly connected.

[0015] Activated carbon filters can effectively absorb odors, harmful gases and volatile organic compounds in the air, thereby purifying the air discharged from the air outlet pipe, improving air quality and protecting the environment.

[0016] Furthermore, an inclined baffle is provided at a position corresponding to the inner wall of the machine body and the air inlet pipe.

[0017] When the dust-laden air enters the machine body from the air inlet pipe, it is blocked by the inclined baffle and flows downward and spreads, so that it can be evenly distributed on the lower side of the filter cartridge, so that the four filter cartridges can fully utilize their filtering capacity, improve the filtering effect, and reduce the excessive load of some filter cartridges, which helps to reduce the blockage of the filter cartridge and reduce the cleaning frequency.

DETAILED DESCRIPTION

[0021] The utility model is described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, a dust collecting device with a pulse electromagnetic valve comprises a body 100, a fan 101 is installed on the top of the body 100, an air outlet pipe 102 is arranged on the upper surface of the body 100, an air inlet pipe 103 is arranged on the side surface of the body 100 near its bottom, a partition plate 104 is installed inside the body 100, four through holes 105 are opened on the surface of the partition plate 104, four filter cartridges 106 are installed on the lower surface of the partition plate 104, and the four filter cartridges 106 correspond to the four through holes 105 one by one. A diverter bottle 107 is installed on the upper surface of the partition plate 104, the diverter bottle 107 is connected to an external air source, and L-shaped nozzles 108 are connected to the outer surfaces of both sides of the diverter bottle 107, and the ends of the L-shaped nozzles 108 correspond to the center of the filter cartridge 106, and a pulse electromagnetic valve 109 is arranged on the outer surface of the L-shaped nozzle 108.

[0023] When in use, the air inlet pipe 103 is connected to the dust suction pipe, the diversion bottle 107 is connected to the external air source, and then the fan 101 is started. The fan 101 generates suction and acts on the end of the dust suction pipe to achieve the purpose of dust suction. The sucked dust enters the inside of the machine body 100 through the air inlet pipe 103, is filtered by the filter cartridge 106, and is discharged from the air outlet pipe 102. The dust is filtered by the filter cartridge 106 and adheres to its surface. When there is a lot of dust attached to the outer surface of the filter cartridge 106, the suction force is reduced and the dust is affected. When the dust suction effect is desired, the pulse solenoid valve 109 can be started, and the high-pressure gas enters the diversion bottle 107 and is diverted to the four L-shaped nozzles 108. When the gas speed passing through the L-shaped nozzle 108 is very high and the time is very short, the gas ejected from the end of the L-shaped nozzle 108 has a large kinetic energy, and the dust attached to the outer surface of the filter cartridge 106 can be blown off, thereby achieving the purpose of self-cleaning. There is no need to remove the filter cartridge 106, ensuring normal production operation, which is beneficial to the production and operation of the enterprise.

[0024] Specifically, a dust box 201 is installed at the bottom of the body 100 through a slide rail 200. The dust box 201 is located directly below the filter cartridge 106. An inspection door 202 is provided on the outer surface of the body 100 corresponding to the dust box 201. The dust blown off the filter cartridge 106 falls into the dust box 201. When the dust in the dust box 201 is collected to a certain extent, the inspection door 202 can be opened to pull the dust box 201 out for cleaning.

[0025] Specifically, a pair of differential pressure sensors 300 are installed on the inner wall of the body 100, and the two differential pressure sensors 300 are respectively arranged on the upper and lower sides of the partition plate 104. The differential pressure sensor 300 is used to detect the internal and external pressure difference of the filter cartridge 106. The larger the pressure difference, the more serious the blockage of the filter cartridge 106. By observing the size of the pressure difference, it is convenient to help workers understand the usage of the filter cartridge 106 and facilitate timely cleaning.

[0026] Specifically, an observation window 400 is provided on the outer surface of the body 100 corresponding to the diverter bottle 107. The material of the observation window 400 is tempered glass. The differential pressure sensor 300 can only respond to the internal and external pressure difference of the filter cartridge 106. When three of the filter cartridges 106 are cleaned and one of the filter cartridges 106 is not cleaned, the detected pressure difference is usually a normal value. Therefore, by setting the observation window 400, workers can observe the use of the filter cartridge 106 and the pulse solenoid valve 109 from the outside to avoid the situation where a pulse solenoid valve 109 is damaged and the filter cartridge 106 cannot be purged.

[0027] Specifically, an activated carbon filter 500 is installed at the end of the air outlet pipe 102. The activated carbon filter 500 is threadedly connected to the air outlet pipe 102. The activated carbon filter 500 can effectively absorb odors, harmful gases and volatile organic compounds in the air, thereby purifying the air discharged from the air outlet pipe 102, improving air quality and protecting the environment.

[0028] Specifically, an inclined baffle 600 is provided at the inner wall of the body 100 corresponding to the air inlet pipe 103. When the dust-laden air enters the body 100 from the air inlet pipe 103, it is blocked by the inclined baffle 600 and flows downward and spreads, so that it can be evenly distributed on the lower side of the filter cartridge 106, so that the four filter cartridges 106 can fully utilize their filtering capacity, improve the filtering effect, and reduce the excessive load of some filter cartridges 106, which helps to reduce the blockage of the filter cartridge 106 and reduce the cleaning frequency.

[0029] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the utility model are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the utility model, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
