Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a pulse dust collector. Background Art

[0002] Explosive destruction is a complex and highly specialized procedure designed to safely eliminate the threat posed by explosives to public safety. Common destruction methods include, but are not limited to: explosion, burning, solidification, chemical analysis and water cutting. Explosion or burning is usually used for waste explosives, shells, detonators, etc. Explosion-proof furnaces are inevitably used in both explosion and burning. Explosion-proof furnaces can withstand the explosive power of explosives and avoid damage to the surrounding areas caused by the explosion of explosives. After the explosion of explosives in the explosion-proof furnace, a large amount of dust and solid residue will be generated. In order to prevent the dust and solid residue from entering the air and affecting the surrounding environment, a buffer is usually used to first collect the high-pressure gas generated in the explosion-proof furnace, release the pressure, and then pass it into a pulse dust collector for dust removal.

[0003] The pulse dust collector in the prior art has poor ability to cope with large amounts of dust in a short period of time. Once a filter bag is damaged, although the filter bag can be replaced without stopping the machine, due to the arrangement positions of multiple filter bags, it is more difficult to replace the filter bags at individual positions and the replacement time is longer.

The filter element 400 has an internal space 411. The internal space 411 and the two rotating parts 300 form a sealed space. The several filter elements 400 are distributed at intervals along the circumference of the axis of the rotating part 300. The dust-containing gas introduced into the air intake space 110 passes through the filter element 400 and enters the air outlet space 120; there are several first solenoid valves 500, and the several first solenoid valves 500 are all arranged on the rotating part 300 close to the air intake space 110. The first solenoid valves 500 correspond to the filter element 400 one by one, and the first solenoid valve 500 is used to connect or close the filter element 400 and the air intake space 110.

[0040] In this embodiment, the fixed plate 200 separates the air inlet space 110 and the air outlet space 120 in the housing 100, and the filter element 400 is located between the two fixed plates 200. The gas in the air inlet space 110 enters the air outlet space 120 through the filter element 400, and the filter element 400 filters the passing gas. After the first solenoid valve 500 is closed, the gas in the air inlet space 110 cannot enter the filter element 400. After the first solenoid valve 500 is opened, the gas in the air inlet space 110 can enter the air outlet space 120 through the filter element 400, thereby completing the filtering of the air. A plurality of first solenoid valves 500 correspond to a plurality of filter elements 400 one by one, and a single filter element 400 can be controlled to be opened or closed by the first solenoid valve 500. When a filter element 400 is damaged and needs to be replaced, the corresponding filter element 400 can be closed through the first solenoid valve 500 to prevent leakage of dust-containing gas, and then the rotating member 300 is rotated to adjust the damaged filter element 400 to a suitable position for replacement, thereby preventing mutual interference between several filter elements 400, thereby increasing the difficulty of replacing the filter element 400. The internal space 411 of the filter element 400 can cooperate with the two fixing plates 200 to seal the internal space 411, and the two ends of the internal space 411 are respectively connected to the air inlet space 110 and the air outlet space 120. After the internal space 411 is sealed, the gas in the air inlet space 110 can only enter the air outlet space 120 through the filter element 400, ensuring that the gas in the air outlet space 120 is completely filtered.

[0041] In actual use, dust-laden gas enters from the air intake space 110, and part of the particles in the air intake space 110 will fall into the dust collecting space 130 under the action of gravity, and other particles follow the gas into the filter element 400, and the filter element 400 filters the dust-laden gas. The filtered gas enters the air outlet space 120 and is discharged.

[0042] Furthermore, the lower rotating member 300 is closer to the air inlet space 110 than the upper rotating member 300, the lower rotating member 300 has a plurality of first through holes 310, the upper rotating member 300 has a plurality of second through holes 320, the plurality of first through holes 310 are all connected to the air inlet space 110, the plurality of first solenoid valves 500 are respectively arranged at the plurality of first through holes 310, the plurality of second through holes 320 are connected to the air outlet space 120, the lower rotating member 300 also has a plurality of first mounting holes 330, the upper rotating member 300 also has a plurality of second The mounting hole 340, the first mounting hole 330 and the second mounting hole 340 are used to mount the filter element 400, and also include a sliding plate 600, which is slidably arranged in the first mounting hole 330. After the sliding plate 600 slides, it approaches or moves away from the upper rotating member 300. After one end of the filter element 400 enters the first mounting hole 330, the filter element 400 abuts against the sliding plate 600; the two ends of the elastic member 700 are respectively arranged on the lower rotating member 300 and the sliding plate 600, and the elastic member 700 is used to provide a force for the sliding plate 600 to approach the lower rotating member 300.

[0043] In this embodiment, the two rotating members 300 are divided into an upper rotating member 300 and a lower rotating member 300 relative to the ground. The lower rotating member 300 has a first through hole 310 connected to the air intake space 110, and the first through hole 310 corresponds one-to-one to the filter element 400. The first solenoid valve 500 controls the opening and closing of the first through hole 310 to stop or start filtering the gas for one of the filter elements 400. The upper rotating member 300 has a second through hole 320 connected to the gas outlet space 120. After the gas is filtered by the filter element 400, it enters the gas outlet space 120 through the second through hole 320. The first mounting hole 330 and the second mounting hole 340 are used to install the filter element 400. After one end of the filter element 400 enters the first mounting hole 330, the sliding plate 600 slides, the elastic member 700 is compressed, and the other end of the filter element 400 is aligned with the second mounting hole 340. The filter element 400 is released. Under the action of the elastic member 700, the sliding plate 600 will push the other end of the filter element 400 into the second mounting hole 340, and the filter element 400 is fixed by the elastic force of the elastic member 700. The filter element 400 can be quickly disassembled and assembled through the first mounting hole 330, the second mounting hole 340, the sliding plate 600 and the elastic member 700, and the convenience of disassembly and assembly of the filter element 400 is further improved.

[0044] Furthermore, the filter element 400 includes a sleeve 410, and both ends of the sleeve 410 are slidably set in the first mounting hole 330 and the second mounting hole 340 respectively. After sliding, the sleeve 410 enters or leaves the first mounting hole 330 or the second mounting hole 340, and the interior of the sleeve 410 is connected to the air intake space 110; the filter bag 420 is set in the sleeve 410, and the side wall of the filter bag 420 is used to isolate smoke and dust, and the interior of the filter bag 420 is connected to the air outlet space 120.

[0045] In this embodiment, the filter element 400 is composed of a sleeve 410 and a filter bag 420. The sleeve 410 has an internal space 411. The filter bag 420 is located in the internal space 411. After the two ends of the sleeve 410 enter the first mounting hole 330 and the second mounting hole 340 respectively, the sliding plate 600 closes one end of the sleeve 410 so that the gas in the air intake space 110 can only enter the internal space 411 through the first through hole 310. The other end of the sleeve 410 and the filter bag 420 close the internal space 411, so that the gas entering the internal space 411 can only pass through the side wall of the filter bag 420 and enter the air outlet space 120 from the inside of the filter bag 420 through the second through hole 320.

[0046] Furthermore, there are a plurality of gas pulsers 800 , which are all disposed in the gas outlet space 120 , and the gas pulsers 800 correspond one-to-one to the filter bags 420 , and the gas pulsers 800 are used for back-blowing the filter bags 420 .

[0047] In this embodiment, the gas pulser 800 can pass high-pressure air from the air outlet space 120 into the interior of the filter bag 420. The high-pressure air can back-blow the filter bag 420 from the interior of the filter bag 420. The dust adsorbed on the filter bag 420 will be blown into the internal space 411 and enter the air intake space 110 through the first through hole 310 under the action of gravity, and finally fall into the dust collecting space 130. The filter bag 420 can be cleaned by the back-blow of the gas pulser 800 to prevent excessive dust accumulation from affecting the gas passage efficiency.

[0048] Furthermore, the filter bag 420 is cylindrical and further includes a baffle 421 , which is disposed at one end of the filter bag 420 away from the gas pulser 800 . After the gas pulser 800 blows air, the gas pushes the baffle 421 .

[0049] In this embodiment, the baffle 421 is arranged at one end of the filter bag 420 away from the gas pulser 800. When the gas pulser 800 back-blows the filter bag 420, the baffle 421 can block the high-pressure gas, and the elastic member 700 is compressed. After the back-blow stops, the elastic member 700 stretches to shake the filter bag 420, thereby improving the cleaning effect of the filter bag 420. In addition, the filter bag 420 does not adopt a scraping method, which can increase the service life of the filter bag 420.

[0050] Furthermore, it also includes a second solenoid valve 900, which is arranged at the bottom of the shell 100, and the second solenoid valve 900 is used to open or close the dust collecting space 130; after the second solenoid valve 900 of the dust box 1000 is opened, the dust in the dust collecting space 130 falls into the dust box 1000.

[0051] In this embodiment, the second solenoid valve 900 is arranged at the bottom of the shell 100. After the second solenoid valve 900 is opened, the dust in the dust collecting space 130 will fall into the dust collecting box 1000 under the action of gravity. Regularly discharging the dust in the dust collecting space 130 can enable the dust collector to maintain long-term uninterrupted operation.

[0052] Furthermore, it also includes a plurality of water spray outlets 1100 , which are arranged in a circular array on the housing 100 . After the water spray outlets 1100 spray water, an annular water curtain is formed, and the dust collecting box 1000 is located in the annular water curtain.

[0053] In this embodiment, since the dust settled in the dust collector is very fine, the water curtain formed by the water spray port 1100 can be opened when the second solenoid valve 900 is opened to prevent a large amount of dust from diffusing into the air.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
