At this time, the limiter releases the restriction on the extension of the adjustment spring, and the adjustment spring can push the second cloth bag when it is extended. In the process of pushing the second cloth bag, the first cloth bag and the second cloth bag oscillate at the same time, and impurities attached to the first cloth bag and the second cloth bag can fall off, thereby realizing timely cleaning of the first cloth bag and the second cloth bag, ensuring that the first cloth bag and the second cloth bag maintain good filtering performance, thereby improving the gas processing efficiency.

Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, and in particular to a self-cleaning pulse bag dust collector. Background Art

[0002] In many industrial production and environmental governance fields, dust removal is of vital importance, and it is related to many aspects such as air quality, equipment operation, and production safety. The existing dust removal device is usually a bag dust collector. When the bag dust collector is performing dust removal operation, the gas carrying particulate matter is passed into the bag, and the impurities in the gas are intercepted inside the bag. In order to ensure that the bag can be used stably for a long time, it is necessary to regularly clean the impurities that block the bag. During the cleaning process, the exhaust device needs to be turned off first. This operation method not only interrupts the normal dust removal process, but also may affect the continuity of gas flow in the entire production system, causing certain inconveniences to production. Moreover, when cleaning the impurities that block the bag, the impurities are tightly adsorbed on the surface of the bag, and external vibration is required to make them fall off. However, this cleaning method has obvious disadvantages. On the one hand, the impurities that fall down are often accumulated inside the bag, which is very difficult to clean up later and easily causes secondary blockage; on the other hand, the entire process of cleaning the bag requires manual observation and control of the cleaning time. Due to the subjectivity and uncertainty of manual judgment, it is difficult to accurately determine the best time for cleaning, so it is impossible to ensure that the bag maintains a stable and good dust removal effect. Summary of the invention

[0003] The invention provides a self-cleaning pulse bag dust collector to solve the problem that the existing bag dust collector cannot clean the bag in time.

[0004] A self-cleaning pulse bag dust collector of the present invention adopts the following technical solution:

When the driving sleeve rotates, the inclined surface of the limiting rod is squeezed by the fixed sleeve, so that the limiting rod slides along the radial direction of the first connecting sleeve.

[0010] Furthermore, the driving member further comprises a reset spring, wherein the reset spring is arranged between the driving sleeve and the limiting rod, and the reset spring is used for driving the limiting rod to reset along the radial direction of the first connecting sleeve.

[0011] Furthermore, a driving disk is provided on the second connecting sleeve, and the driving disk is rotatably connected to the second connecting sleeve, and the driving disk is slidably connected to the second connecting sleeve up and down, and when the air pressure in the dust removal chamber is greater than a first preset value, the driving disk can be pushed to slide upward; when the air pressure in the dust removal chamber is less than the first preset value, the driving disk can push the driving sleeve to rotate when sliding downward.

[0012] Furthermore, the upper end of the driving sleeve is provided with guiding bevel teeth, and the lower end of the driving disk is provided with extruding bevel teeth. When the driving disk slides downward, the extruding bevel teeth can squeeze the guiding bevel teeth to make the driving sleeve rotate.

[0013] Furthermore, a storage shell is provided in the dust removal chamber, and the storage shell is coaxially slidably connected to the first connecting sleeve.

In the initial state, the adjusting spring is in a compressed state, the adjusting spring is arranged between the first bag and the second bag, and the elongation of the adjusting spring is limited by arranging a limiter to ensure that the dust removal chamber is in a stable state. When the filter is blocked, the air pressure in the dust removal chamber increases, and the sensing component can timely sense the air pressure inside the dust removal chamber. When the air pressure inside the dust removal chamber is greater than a first preset value, the air supply component reduces the air supply to the dust removal chamber, so that the air pressure in the dust removal chamber gradually decreases. At this time, the limit member releases the restriction on the elongation of the adjustment spring, and the adjustment spring can push the second bag when it is elongated. In the process of pushing the second bag, the first bag and the second bag oscillate at the same time, and impurities attached to the first bag and the second bag can fall off, thereby realizing timely cleaning of the first bag and the second bag, ensuring that the first bag and the second bag maintain good filtering performance, thereby improving the gas processing efficiency.

[0030] like Figures 1 to 8 As shown, an embodiment of the present invention provides a self-cleaning pulse bag dust collector, which includes a bracket 110, a dust removal component, a sensor component and an adjustment component.

[0031] The bracket 110 is fixedly arranged on the ground, and the bracket 110 has a horizontal upper end surface. The dust removal part includes a first cloth bag 130 and a second cloth bag 140. The first cloth bag 130 is fixedly connected to the bracket 110. The bracket 110 is provided with a support member, and the support member is used to support the first cloth bag 130. Specifically, the support member includes two support rods 120, and the two support rods 120 are vertically arranged. The two support rods 120 are distributed on the front and rear sides of the first cloth bag 130. The lower end of each support rod 120 is fixedly connected to the upper end surface of the bracket 110, and the upper end of each support rod 120 is fixedly connected to the upper end of the first cloth bag 130. Under the action of the first cloth bag 130's own gravity, the lower end of the first cloth bag 130 is in a state of abutting against the upper end surface of the bracket 110. The upper end of the second bag 140 is fixedly connected to the upper end of the first bag 130. The second bag 140 and the first bag 130 are coaxially arranged. The second bag 140 can fall into the first bag 130 under the action of its own gravity. The second bag 140 and the first bag 130 are set at intervals, and a relatively closed dust removal chamber 150 is formed between the first bag 130 and the second bag 140. Figure 4 As shown, the dust removal chamber 150 is slightly U-shaped. An air supply member is provided on the bracket 110, and the air supply member is used to supply air into the dust removal chamber 150. Specifically, the air supply member includes an air supply pump 160, and the air supply pump 160 has an air outlet pipe 170. The upper end of the first cloth bag 130 is provided with an air inlet 180 connecting the dust removal chamber 150 and the external environment. The air outlet pipe 170 extends to the inside of the dust removal chamber 150 through the air inlet 180. When the air supply pump 160 is started, the gas in the external environment can be transported to the inside of the dust removal chamber 150, and the gas entering the dust removal chamber 150 can pass through the first cloth bag 130 or the second cloth bag 140, and the first cloth bag 130 or the second cloth bag 140 can intercept impurities in the gas, thereby filtering the gas.

[0032] The sensing component is used to sense the air pressure in the dust removal chamber 150. Specifically, as the gas enters the dust removal chamber 150, impurities carried in the gas gradually adhere to the side wall of the first cloth bag 130 or the second cloth bag 140, and the air permeability of the first cloth bag 130 or the second cloth bag 140 gradually decreases. If the air supply component maintains a constant air supply to supply air to the dust removal chamber 150, the air pressure in the dust removal chamber 150 will gradually increase. When the air pressure in the dust removal chamber 150 is greater than a first preset value, the air supply component reduces the air supply to the dust removal chamber 150, so that the air pressure in the dust removal chamber 150 gradually decreases, wherein the first preset value is a manually set reference parameter.

[0033] The adjusting member includes an adjusting spring 260 and a limiting member. The adjusting spring 260 is arranged between the first cloth bag 130 and the second cloth bag 140. Specifically, in the initial state, the adjusting spring 260 is in a compressed state, the adjusting spring 260 is arranged vertically, the upper end of the adjusting spring 260 is connected to the second cloth bag 140, and the lower end of the adjusting spring 260 is connected to the first cloth bag 130. The limiting member is used to limit the extension of the adjusting spring 260. Under the action of the limiting member, the lower end of the first cloth bag 130 and the lower end of the second cloth bag 140 are in a state of being close to each other. When the limiting member releases the restriction on the extension of the adjusting spring 260, the adjusting spring 260 can be actively reset. When the adjusting spring 260 is actively reset, the second cloth bag 140 and the first cloth bag 130 are driven away from each other, thereby achieving the effect of shaking the first cloth bag 130 and the second cloth bag 140, and the impurities attached to the first cloth bag 130 and the second cloth bag 140 can be actively separated. When the air pressure in the dust removal chamber 150 changes from a state greater than the first preset value to a state less than the first preset value, the limit member releases the restriction on the extension of the adjustment spring 260, and the sensing member timely senses the air pressure in the dust removal chamber 150 to ensure that the limit member can promptly release the restriction on the extension of the adjustment spring 260, thereby ensuring that the first cloth bag 130 and the second cloth bag 140 can be cleaned in time.

[0034] A self-cleaning pulse bag dust collector of the present invention, when removing dust from the gas carrying impurities, transports the gas carrying impurities into the dust removal chamber 150 through the air supply member, and the gas entering the dust removal chamber 150 can pass through the first cloth bag 130 or the second cloth bag 140. When the gas passes through the first cloth bag 130 or the second cloth bag 140, the impurities in the gas can be intercepted in the dust removal chamber 150. In the initial state, the adjustment spring 260 is in a compressed state, and the adjustment spring 260 is arranged between the first cloth bag 130 and the second cloth bag 140. The elongation of the adjustment spring 260 is limited by setting a limiter to ensure that the dust removal chamber 150 is in a stable state. When the first cloth bag 130 and the second cloth bag 140 are blocked by impurities, the air pressure in the dust removal chamber 150 increases, and the sensor The sensing component can timely sense the air pressure inside the dust removal chamber 150. When the air pressure inside the dust removal chamber 150 is greater than a first preset value, the air supply component reduces the air supply to the dust removal chamber 150, so that the air pressure in the dust removal chamber 150 gradually decreases. At this time, the limit member releases the restriction on the extension of the adjustment spring 260. When the adjustment spring 260 is extended, it can push the second cloth bag 140. In the process of pushing the second cloth bag 140, the first cloth bag 130 and the second cloth bag 140 oscillate at the same time, and impurities attached to the first cloth bag 130 and the second cloth bag 140 can fall off, thereby realizing timely cleaning of the first cloth bag 130 and the second cloth bag 140, ensuring that the first cloth bag 130 and the second cloth bag 140 maintain good filtering performance, thereby improving the gas processing efficiency.

[0035] In one embodiment, the adjustment member further includes a first connecting sleeve 210 and a second connecting sleeve 220, wherein the first connecting sleeve 210 is fixedly connected to the first cloth bag 130, the first connecting sleeve 210 is coaxially arranged with the first cloth bag 130, and the first connecting sleeve 210 is always arranged in the dust removal chamber 150. The second connecting sleeve 220 is fixedly connected to the second cloth bag 140, the second connecting sleeve 220 is coaxially arranged with the second cloth bag 140, and the second connecting sleeve 220 is always arranged in the dust removal chamber 150. Further, the first connecting sleeve 210 includes a first disc 211 and a first circular sleeve 212, the first disc 211 is fixedly connected to the first cloth bag 130, the inner diameter of the first circular sleeve 212 is equal to the outer diameter of the first disc 211, and the lower end of the first circular sleeve 212 is fixedly connected to the first disc 211. The second connecting sleeve 220 includes a second disc 221 and a second sleeve 222. The outer diameter of the second disc 221 is equal to the outer diameter of the first sleeve 212, and the outer diameter of the second sleeve 222 is smaller than the inner diameter of the first sleeve 212. The adjusting spring 260 is fixedly connected between the first connecting sleeve 210 and the second connecting sleeve 220. Specifically, the adjusting spring 260 is vertically arranged, the lower end of the adjusting spring 260 is fixedly connected to the first disc 211, and the upper end of the adjusting spring 260 is fixedly connected to the lower end of the second sleeve 222. In the initial state, the adjusting spring 260 is in a compressed state, and the upper end of the first sleeve 212 and the second disc 221 are in an abutting state. Further, the first connecting sleeve 210 and the second connecting sleeve 220 are both made of hard materials, and the first connecting sleeve 210 and the second connecting sleeve 220 can provide a mounting base for the adjusting spring 260.

[0036] In one embodiment, the limiting member includes a limiting rod 230 and a driving member, the limiting rod 230 is slidably arranged along the radial direction of the first connecting sleeve 210, specifically, the limiting rod 230 is arranged along the radial direction of the first circular sleeve 212, the limiting rod 230 remains unchanged in the height direction of the first circular sleeve 212, and the limiting rod 230 can be inserted into the gap of the adjustment spring 260, so that the limiting rod 230 hinders the extension of the adjustment spring 260. When the air pressure in the dust removal chamber 150 changes from a state greater than the first preset value to a state less than the first preset value, the driving member drives the limiting rod 230 to slide along the radial direction of the first connecting sleeve 210, so that the limiting rod 230 is pulled out of the gap of the adjustment spring 260, and then the limiting rod 230 releases the restriction on the extension of the adjustment spring 260.

[0037] In one embodiment, the driving member includes a fixing sleeve 240 and a driving sleeve 250, wherein the fixing sleeve 240 is coaxially fixedly connected to the first connecting sleeve 210, specifically, the fixing sleeve 240 is coaxially fixedly connected to the first disc 211 of the first connecting sleeve 210, the outer diameter of the fixing sleeve 240 is smaller than the inner diameter of the first circular sleeve 212, and the fixing sleeve 240 is disposed inside the first circular sleeve 212. The driving sleeve 250 is coaxially rotatably connected to the first connecting sleeve 210, the driving sleeve 250 is coaxially rotatably connected to the first circular sleeve 211 of the first connecting sleeve 210, the outer diameter of the driving sleeve 250 is smaller than the inner diameter of the fixing sleeve 240, and the driving sleeve 250 is disposed inside the fixing sleeve 240. The adjustment spring 260 is arranged between the fixed sleeve 240 and the first circular sleeve 212, the limit rod 230 slides through the fixed sleeve 240 and the driving sleeve 250, the limit rod 230 can slide along the radial direction of the fixed sleeve 240 and the driving sleeve 250, the limit rod 230 is arranged horizontally, and a side wall of the limit rod 230 in the length direction is arranged as an inclined surface, when the driving sleeve 250 rotates, the inclined surface of the limit rod 230 can form an extrusion with the fixed sleeve 240, so that the limit rod 230 passively slides along the radial direction of the driving sleeve 250 until the limit rod 230 is separated from the extrusion adjustment spring 260. Further, when the air pressure in the dust removal chamber 150 changes from a state greater than the first preset value to a state less than the first preset value, the driving sleeve 250 starts to rotate around its own axis.

[0038] In one embodiment, the driving member further includes a reset spring 270, which is disposed between the driving sleeve 250 and the limiting rod 230. Specifically, a retaining ring is disposed on the limiting rod 230, and the retaining ring is coaxially disposed with the limiting rod 230. The retaining ring is disposed between the fixing sleeve 240 and the driving sleeve 250, and the reset spring 270 is coaxially sleeved on the outer side of the limiting rod 230. One end of the reset spring 270 is fixedly connected to the retaining ring, and the other end of the reset spring 270 is fixedly connected to the driving sleeve 250. When the driving sleeve 250 rotates, the limiting rod 230 is rotated. The rod 230 gradually approaches the axis of the driving sleeve 250 along the radial direction of the driving sleeve 250. During this process, the reset spring 270 is gradually squeezed and deformed. After the limit rod 230 releases the restriction on the extension of the adjustment spring 260, and the adjustment spring 260 resets and extends, the reset spring 270 begins to actively reset. During the reset process of the reset spring 270, the limit rod 230 is driven to reset. During the reset process of the limit rod 230, the inclined surface of the limit rod 230 squeezes the side wall of the fixed sleeve 240, so that the driving sleeve 250 rotates in the opposite direction to reset.

[0039] In one embodiment, a driving disk 310 is provided on the second connecting sleeve 220, and the driving disk 310 is rotatably connected to the second connecting sleeve 220, and the driving disk 310 is slidably connected to the second connecting sleeve 220 up and down. Specifically, the driving disk 310 is horizontally arranged, and a rotating shaft is fixedly arranged on the upper end of the driving disk 310. A limiting sleeve 320 is fixedly arranged on the second disc 221 of the second connecting sleeve 220. The outer diameter of the limiting sleeve 320 is smaller than the inner diameter of the second circular sleeve 222. The outer diameter of the driving disk 310 is equal to the inner diameter of the limiting sleeve 320. The driving disk 310 can slide in the limiting sleeve 320, and the rotating shaft on the driving disk 310 passes through the second disc 221 and the second cloth bag 140, and the rotating shaft extends to the outside of the second cloth bag 140. The driving disk 310 can rotate and slide in the limiting sleeve 320, the first circular sleeve 212 of the first connecting sleeve 210 can be air-permeable, the air pressure in the dust removal chamber 150 is the same as the air pressure inside the first circular sleeve 212, when the air pressure in the dust removal chamber 150 is greater than the first preset value, the air pressure inside the first circular sleeve 212 is also greater than the first preset value, and the driving disk 310 slides upward under the action of the pressure difference. When the air pressure in the dust removal chamber 150 changes from greater than the first preset value to less than the first preset value, the driving disk 310 slowly moves downward under the action of its own gravity, and the driving sleeve 250 rotates during the downward sliding process of the driving disk 310.

[0040] In one embodiment, the upper end of the driving sleeve 250 is provided with a guiding bevel gear 330, and the lower end of the driving disk 310 is provided with an extruding bevel gear 340. When the driving disk 310 slides downward, the extruding bevel gear 340 can squeeze the guiding bevel gear 330, and the driving sleeve 250 rotates. Specifically, when the driving disk 310 is in the initial state, the extruding bevel teeth 340 do not contact the guiding bevel teeth 330. After the driving disk 310 moves up, the driving disk 310 rotates. When the driving disk 310 moves down again, the extruding bevel teeth 340 on the driving disk 310 contact the guiding bevel teeth 330. Furthermore, a first baffle rod 430 is fixedly provided on the driving disk 310, and a second baffle rod 440 is fixedly provided on the first disc 211.

In the initial state, the air pressure in the dust removal chamber 150 is not greater than the first preset value. As the first cloth bag 130 and the second cloth bag 140 filter the gas, the dust removal chamber 150 The air pressure inside gradually becomes greater than the first preset value. When the air pressure inside the dust removal chamber 150 is greater than the first preset value, the driving disk 310 gradually moves up, and the first auxiliary teeth 410 on the driving disk 310 collide with the second auxiliary teeth 420 on the second disc 221, so that the driving disk 310 rotates. After the driving disk 310 rotates, the first gear rod 430 and the second gear rod 440 contact each other. When the air pressure in the dust removal chamber 150 changes from greater than the first preset value to less than the first preset value, the driving disk 310 slowly moves down under the action of its own gravity. At this time, the extrusion bevel teeth 340 on the driving disk 310 can squeeze the guide bevel teeth 330 on the driving sleeve 250. Under the action of the first gear rod 430 and the second gear rod 440, the driving disk 310 will not rotate, so that the driving sleeve 250 rotates around its own axis.

[0041] In one embodiment, a storage shell 350 is disposed in the dust removal chamber 150. The storage shell 350 is coaxially disposed with the first circular sleeve 212. The storage shell 350 is penetrated by the first circular sleeve 212. The storage shell 350 is slidingly connected with the first circular sleeve 212. The storage shell 350 is a slightly cylindrical structure with the opening facing downward. The lower end of the storage shell 350 abuts against the lower end of the first cloth bag 130. When the storage shell 350 abuts against the first cloth bag 130, the interior of the storage shell 350 is in a relatively closed state. The storage shell 350 is fixedly connected to the second cloth bag 140 via the first spring 370. The first spring 370 is coaxially arranged with the first circular sleeve 212. The upper end of the first spring 370 is connected to the second cloth bag 140, and the lower end of the first spring 370 is connected to the storage shell 350. In the initial state, the first spring 370 is in a compressed state. Under the action of the first spring 370, the storage shell 350 is in a state of pressing against the lower end of the first cloth bag 130. When the limit rod 230 removes the obstacle to the reset of the adjustment spring 260, the first spring 370 and the adjustment spring 260 are reset at the same time. The adjustment spring 260 is reset. During the process, the storage shell 350 is driven to disengage from the abutment against the first cloth bag 130. When the adjustment spring 260 is reset, the impurities attached to the first cloth bag 130 and the second cloth bag 140 fall off. The fallen impurities can be deposited on the lower end surface of the first cloth bag 130. After the states of the first cloth bag 130 and the second cloth bag 140 are stabilized, the staff manually drives the second cloth bag 140 to reset, so that the adjustment spring 260 is restricted by the limit rod 230 again, and the impurities deposited on the lower end surface of the first cloth bag 130 are intercepted by the storage shell 350, so as to avoid the same impurity blocking the first cloth bag 130 or the second cloth bag 140 for the second time.

[0042] In one embodiment, a sewage outlet is provided on the first cloth bag 130, and a sealing plate is provided on the first cloth bag 130. The sealing plate can block the sewage outlet, and the sewage outlet can be connected to the interior of the storage shell 350. Specifically, after the second cloth bag 140 and the first cloth bag 130 move away from each other, the staff manually drives the second cloth bag 140 to reset to the first cloth bag 130. At this time, the storage shell 350 is transformed into a state of abutting the first cloth bag 130 again. At this time, impurities exist inside the storage shell 350. The sewage outlet is unblocked by the sealing plate, and the impurities in the storage shell 350 can be discharged from the dust removal chamber 150.

[0043] In one embodiment, the sensing component includes an air pressure sensor and a control board. The air pressure sensor is used to sense the air pressure at the air inlet 180 of the dust removal chamber 150. The control board can control the air supply of the air supply component according to the data of the air pressure sensor. Specifically, the output power of the air supply pump 160 can be regulated by the control board. When the output power of the air supply pump 160 decreases, the air supply of the air supply pump 160 to the dust removal chamber 150 is reduced. The control board can compare the actual data of the air pressure sensor with the first preset value. When the actual data of the air pressure sensor is greater than the first preset value, the control board reduces the output power of the air supply pump 160, thereby causing the air pressure in the dust removal chamber 150 to gradually decrease to below the first preset value.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
