Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, specifically a dust removal device that allows for convenient replacement of filter cartridges. Background Technology

[0002] Dust collection equipment is an environmentally friendly device used to remove suspended particulate matter, dust, and harmful substances from the air. It is widely used in industry, construction, and home applications. Its core principle involves separating gas and particulate matter through physical filtration (such as filter bags and cartridges), electrostatic adsorption, wet scrubbing, or mechanical centrifugation, effectively reducing air pollution. In industrial settings, common types include baghouse dust collectors, electrostatic precipitators, and cyclone dust collectors.

[0003] For example, authorization announcement number CN216367123U discloses a new type of filter cartridge dust collector. Existing devices are inconvenient for cleaning dust on the surface of the filter cartridges, reducing work efficiency. Moreover, the dust inside the dust collection drawer is easily blown out by external wind when it is removed or during transportation, causing environmental pollution. The proposed device includes a housing with a connecting pipe fixed to its lower surface. A dust collection component is installed on the lower surface of the connecting pipe. An installation plate is fixed inside the housing, and filter cartridge components are installed at equal intervals inside the installation plate. By setting up the dust collection component, it is not only convenient to handle the dust inside the device, but also to prevent the dust inside the device from being blown out by external wind, thereby reducing environmental pollution. By setting up a cleaning component, the outer surface of the filter cartridge components can be cleaned during use without disassembling the filter cartridge components for cleaning, thus improving work efficiency.

[0004] Since filter cartridges require maintenance and replacement after prolonged use, the aforementioned technology fixes the entire filter cartridge inside the dust removal equipment, requiring personnel to disassemble and reassemble the filter cartridge inside the equipment, which is quite cumbersome. Therefore, there is an urgent market need to develop a dust removal device that allows for easy replacement of filter cartridges to help people solve the existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a dust removal device with convenient filter cartridge replacement, comprising a filter box 1. Four filter cartridges 3 are arranged in a circular array in the center of the filter box 1. Each of the four filter cartridges 3 has a tubular filter screen 301 in its center. An exhaust canister 2 is fixedly connected to the front end of the filter box 1. Four circular connecting seats 202 are fixedly connected in a circular array to the front end face of the exhaust canister 2. The front ends of the four filter cartridges 3 extend sequentially through the front end of the filter box 1 and the center of the four circular connecting seats 202, and are each fixedly connected to a connecting circular plate 305. Multiple strip-shaped air outlets 304 are arranged in a circular array on the outer wall of the four filter cartridges 3 and inside the exhaust canister 2. A second sealing ring 203 is fixedly connected to the front end face of each circular connecting seat 202. Each connecting circular plate 305 is connected to... The front ends of the circular connecting seats 202 are fixedly connected by multiple first bolts 306. The circular connecting plate 305 is fixed to the circular connecting seat 202 and sealed by the second sealing ring 203, so that the filter cartridge 3 is stably set inside the filter box 1 and the exhaust tank 2. The flue gas inlet pipe 107 is provided in the middle of the rear end face of the filter box 1. The exhaust pipe 201 is fixedly connected to the middle of the front end of the exhaust tank 2. The flue gas enters the filter box 1 through the flue gas inlet pipe 107, is filtered by the tubular filter screen 301, and then enters the filter cartridge 3. It enters the exhaust tank 2 through multiple strip-shaped air outlets 304 and finally exits from the exhaust pipe 201. When the filter cartridge 3 needs to be disassembled, the multiple first bolts 306 are removed, and the filter cartridge 3 is pulled forward by the connecting plate 305 for maintenance and replacement.

[0024] Please see Figure 3 and Figure 4 Four limiting tubes 101 are fixedly connected in a ring array to the rear end face of the filter box 1. Each of the four limiting tubes 101 and the rear end face of the filter box 1 is fixedly connected to a sealing gasket 102. A pulse gas pipe 103 is provided in the middle of the sealing gasket 102. The rear end of the pulse gas pipe 103 extends out of the rear end face of the filter box 1 and is fixedly connected to a pulse gas pump 104. Each of the four filter cartridges 3 is provided with a vent hole 302 in the middle of the rear end face. The rear ends of the four filter cartridges 3 are respectively inserted into the four limiting tubes 101. The four vent holes 302 are respectively connected to the four pulse gas pipes 103. When the filter cartridges 3 filter the flue gas, the pulse gas pump 104 pulses the pulse gas pipes 103 and the vent holes 302 to deliver gas into the filter cartridges 3, which increases the gas pressure inside the filter cartridges 3 instantaneously. This causes the gas inside the filter cartridges 3 to pass through the tubular filter screen 301 in reverse, thereby blowing away the impurities attached to the outer wall of the tubular filter screen 301 in reverse.

[0025] Please see Figure 3Each filter cartridge 3 has a sealing ring 303 fixedly connected to its outer wall and to the front end of the filter box 1. A first sealing ring 105 is fixedly connected to the front end of the filter box 1 and to the rear end of each sealing ring 303. When the connecting circular plate 305 is connected to the circular connecting seat 202 by the first bolt 306, the connecting circular plate 305 will push the filter cartridge 3 to move backward, so that the rear end of the filter cartridge 3 presses against the sealing gasket 102 for sealing. The backward movement of the filter cartridge 3 will simultaneously drive the sealing ring 303 to move backward and press against the first sealing ring 105, so that the outer wall of the filter cartridge 3 is sealed with the front end of the filter box 1. When the connecting circular plate 305 is connected to the circular connecting seat 202, the rear end of the filter cartridge 3 and the sealing gasket 102 and the outer wall of the filter cartridge 3 and the front end of the filter box 1 are sealed simultaneously. The diameter of the circular groove inside the circular connecting seat 202 is larger than the diameter of the sealing ring 303, so that the sealing ring 303 can be pulled out through the circular groove inside the circular connecting seat 202 when the filter cartridge 3 is disassembled.

[0026] Please see Figure 2 and Figure 3 A rectangular connecting ring 106 is fixedly connected to the lower end of the filter box 1. A dust collection box 4 is connected to the lower end of the rectangular connecting ring 106. The upper end of the dust collection box 4 is fixedly connected to the rectangular connecting ring 106 by multiple second bolts 401. The dust inside the filter box 1 is collected through the dust collection box 4.

[0027] Working principle: During use, dust-laden flue gas enters the filter box 1 through the flue gas inlet pipe 107. Under the action of airflow, it is filtered through four tubular filter screens 301. Dust particles are trapped on the outside of the filter cartridge 3. The purified gas enters the inside of the filter cartridge 3 and is discharged into the exhaust tank 2 through the strip-shaped air outlet 304, and finally discharged through the exhaust pipe 201. When the filter cartridge 3 needs to be cleaned, the pulse air pump 104 intermittently sprays high-pressure gas into the inside of the filter cartridge 3 through the pulse air pipe 103 and the air vent 302, forming a reverse airflow that shakes the dust accumulated on the outer wall of the tubular filter screens 301 to the dust collection box 4. When replacing the filter cartridge 3, simply remove the first bolt 306 and pull the connecting circular plate 305 outward to pull the entire filter cartridge 3 out of the limiting pipe 101. The new filter cartridge 3 can be installed by reversing the operation. The sealing pressure ring 303 and the first sealing ring 105, and the connecting circular plate 305 and the second sealing ring 203 form a double sealing guarantee.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
