Description

Technical Field

[0001] The utility model relates to the technical field of pulse dust collectors, in particular to a pulse dust collector which is convenient for cleaning a filter screen. Background Art

[0002] The pulse dust collector is a new type of high-efficiency pulse dust collector improved on the basis of the bag dust collector. It combines the advantages of various pulse jet dust collectors with chamber back-blowing, overcomes the shortcomings of insufficient chamber cleaning intensity and uneven distribution of inlet and outlet air, and expands the scope of application.

[0003] According to the disclosed patent CN215085636U, a pulse dust collector is provided for cleaning the filter, which relates to the technical field of pulse dust collector. The pulse dust collector for cleaning the filter comprises a box, an inner wall of the box is fixedly connected with a connecting plate, a bottom of the connecting plate is fixedly connected with a plurality of cloth bags, a bottom of the connecting plate is provided with a filter plate, the filter plate is fixedly connected with the inner wall of the box, a cleaning assembly is provided on the top of the filter plate, and the cleaning assembly comprises a rotating rod. The pulse dust collector for cleaning the filter is convenient for cleaning the filter. Through the spring between the rotating plate and the moving plate, the moving plate automatically rises and returns after the scraper plate rises. At the same time, the first reciprocating screw rod drives the rotating plate to rotate, and the rotating plate drives the sliding rod to rotate, so that the top of the filter plate is cleaned more thoroughly, so that dust enters the bottom end of the box, and excessive accumulation on the top of the filter plate is avoided, which causes the filter plate to be blocked. During the process of the present utility model, the inventor found that at least the following problems in the prior art have not been solved: by providing a cleaning assembly on the top of the filter plate, the dust accumulated on the surface of the filter plate can be cleaned in and out, and during use, the pulse dust collector currently used will use the corresponding pulse transmitter to impact the bag-type dust bag used inside it. The pulse transmitter is in operation and transmits the pulse gas to the inside of the filter bag from the top of the filter bag. The pulse gas's own kinetic energy is strongest only at the top of the filter bag during the discharge process, which leads to different dust removal and cleaning impact forces on the inner wall at different positions inside the vertically placed filter bag, affecting the overall cleaning quality inside the filter bag, and easily leading to the inability to quickly clean the dust at the bag position far away from the pulse gas discharge port, thus affecting the dust removal and filtration quality of the subsequent dust collector. For this reason, it is necessary to design a new technical solution to solve the problem. Utility Model Content

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0028] Example 1: A pulse dust collector that is easy to clean the filter screen, see Figures 1 to 5The top of the processing frame 1 is detachably mounted with a mounting frame 11 by bolts, and a filter bag 16 is detachably and vertically arranged inside the processing frame 1, and the number of the filter bags 16 is several groups. An exhaust pipe 15 is vertically penetrated and fixedly installed on the top side of the mounting frame 11, and the bottom of the exhaust pipe 15 is movably plugged into the top of the filter bag 16. A fixing rod 2 is vertically mounted at the bottom of the mounting frame 11, and the number of the fixing rod 2 is several groups. The fixing rod 2 is plugged into the top of the filter bag 16, and a fixing plate 21 is fixedly installed at the bottom of each fixing rod 2. A sliding plate 24 is slidably installed between the tops of the sides of each two sets of fixed plates 21, and the sliding plate 24 is located below the exhaust pipe 15. A guide rod 23 is vertically penetrated and slidably installed at the middle end of each sliding plate 24. A fixing frame 22 is fixedly sleeved on the top surface of each guide rod 23, and the outer side of the fixing frame 22 is fixedly connected to the side wall of the fixed plate 21. A transmission rod 25 is vertically fixedly installed on both sides of the bottom of each sliding plate 24. A lifting sleeve 26 is slidably sleeved on the outer side of each guide rod 23. The bottom of the transmission rod 25 and the top of the lifting sleeve 26 are fixedly sleeved. The lifting sleeve 26 is fixedly connected, and the lifting sleeve 26 is located below the sliding plate 24. The outer surface of each lifting sleeve 26 is hinged with a push rod 27 through a rotating shaft, and the push rod 27 penetrates and is slidably inserted into the fixed plate 21. The side of each push rod 27 away from the lifting sleeve 26 is hinged with a flapping arc plate 28 through a rotating shaft, and the flapping arc plate 28 is located between the inner side of the filter bag 16 and the outer side of the fixed plate 21. By arranging a vertically slidable sliding plate 24 below the exhaust port of the exhaust pipe 15, and combining the transmission conversion action of the push rod 27, In this way, the vertical moving force of the lifting sleeve 26 can be converted into a horizontal driving force for the beating arc plate 28 to beat the inner wall of the filter bag 16, thereby providing the same and synchronous beating cleaning force to different vertical positions inside the filter bag 16, further improving the cleaning quality of the inside of the filter bag 16, reducing the manual operation steps required for the operator to clean the filter bag 16, and avoiding insufficient cleaning force of the pulse cleaning gas during the movement of the filter bag 16 inside the filter bag 16, thereby affecting the cleaning quality of the filter bag 16.

[0029] For details, see Figures 1 to 5 A return spring 29 is movably sleeved on the outer surface of the bottom of each guide rod 23, and the top of the return spring 29 is movably fitted to the lower outer side of the lifting sleeve 26. Through the pushing action of the return spring 29, after the cleaning and dust removal of the inside of the filter bag 16 is completed, the lifting sleeve 26 is pushed by the return spring 29 to restore its position, thereby facilitating subsequent cleaning and use.

[0030] For further information, see Figures 1 to 5A fixing ring 32 is fixedly sleeved between the outer sides of the top ends of every two groups of fixing rods 2, and a follower tooth block 33 is fixedly installed on the outer surface of the fixing ring 32, and the number of the follower tooth block 33 is several groups. A rotating motor 3 is fixedly installed at the bottom of the mounting frame 11, and a transmission gear 31 is fixedly sleeved on the bottom of the transmission shaft of the rotating motor 3 through a coupling, and the outer side of the transmission gear 31 and the outer side of the follower tooth block 33 are meshed. Through the meshing transmission action of the transmission tooth block and the follower tooth block 33, when the rotating motor 3 rotates, the fixing rod 2 can be rotated and the flapping position of the flapping arc plate 28 can be rotated and adjusted, thereby increasing the flapping and cleaning range of the flapping arc plate 28 on the inside of the filter bag 16, and further improving the cleaning and dust removal quality of the filter bag 16.

[0031] It is worth noting that see Figures 1 to 5 A limit slider 34 is fixedly installed on the top surface of each fixing rod 2, and a limit slot 35 is provided at the bottom of the mounting frame 11, and the limit slider 34 is slidably inserted into the limit slot 35. Through the limit sliding action of the limit slot 35 on the limit slider 34, when the rotating motor 3 is turned on to drive the fixing rod 2 to rotate, the top of the fixing rod 2 will not be arbitrarily separated from the bottom surface of the mounting frame 11 to affect the subsequent fixed use.

[0032] It is worth noting that see Figures 1 to 5 A pulse transmitter 12 is fixedly installed on the outer surface of the top of the mounting frame 11, and a delivery pipe 13 is fixedly connected to the side of the pulse transmitter 12. The end of the delivery pipe 13 away from the pulse transmitter 12 is fixedly connected to a connecting pipe 14, and the side of the connecting pipe 14 is fixedly connected to an exhaust pipe 15. The corresponding pulse gas can be generated through the structural action of the pulse transmitter 12, which can provide the sliding plate 24 with the power required for vertical movement, while cleaning and removing dust from the inside of the filter bag 16.

[0033] It is worth mentioning that see Figures 1 to 5 A guide groove 4 is provided at the top of the side of each fixed plate 21, and the side of the sliding plate 24 is slidably inserted into the inside of the guide groove 4. A movable groove 5 is provided inside each fixed plate 21, and the push rod 27 is inserted through and slidably inserted into the inside of the movable groove 5. A sliding groove 51 is provided at the middle end of each sliding plate 24, and the guide rod 23 is inserted through and slidably inserted into the inside of the sliding groove 51. The sliding groove 51 guides and slides the sliding plate 24, so that when the sliding plate 24 is impacted by the pulse gas, the sliding plate 24 can only move vertically between the sides of the fixed plate 21 without lateral movement.

[0034] During operation, the filter bags 16 are placed vertically in the processing frame 1 in sequence, and then the installation frame 11 is connected to the cleaning assembly arranged below it and is synchronously installed on the top of the processing frame 1 through bolts, so that the exhaust port of the exhaust pipe 15 and the flapping arc plate 28 can be inside the filter bags 16. After the gas to be treated is transported through the air inlet pipe arranged on the side of the processing frame 1, the gas can flow through the filter bags 16 during transportation, and the gas can be filtered and dusted in combination with the filter bags 16, so that the dust inside the gas is filtered and accumulated on the filter bags 16. The outer side of the filter bag 16 is used to complete the filtration and dust removal of the gas. When it is necessary to clean the dust accumulated on the outer side of the filter bag 16, the pulse transmitter 12 is started to generate a cleaning pulse gas, which is then transported to the exhaust pipe 15 through the delivery pipe 13 and the connecting pipe 14 for discharge. When the gas is transported to the filter bag 16, while the dust is removed from the inside of the filter bag 16, the gas will contact the surface of the sliding plate 24 when it is discharged through the bottom of the exhaust pipe 15, causing an impact on the sliding plate 24, so that the sliding plate 24 can slide along the inner surface of the fixed plate 21 under the guiding sliding action of the guide groove 4. The lifting sleeve 26 is driven to vertically descend on the side of the guide rod 23 under the transmission action of the transmission rod 25, and then the lifting sleeve 26 can be driven to vertically descend synchronously on the outside of the guide rod 23 under the transmission conversion action of the push rod 27, and the sliding guide action of the movable groove 5 on the push rod 27, The vertical movement force of the lifting sleeve 26 is converted into a horizontal driving force for the beating arc plate 28, so that the beating arc plate 28 can move horizontally relative to the inside of the filter bag 16, beat the inside of the filter bag 16 and separate the dust accumulated on its outer surface, and synchronously start the rotating motor 3 to make it run. The transmission gear 31 is driven to rotate. Under the meshing transmission action of the transmission gear 31 and the follower gear block 33, and under the limiting sliding action of the limiting slide groove 35 on the limiting slide block 34, the fixing ring 32 and the fixing rod 2 can be driven to rotate accordingly, and then the fixing plate 21 and the flapping arc plate 28 are driven to rotate inside the filter bag 16 to adjust the cleaning position of the flapping arc plate 28, so that the flapping arc plate 28 can flap and clean different positions inside the filter bag 16, so as to avoid a large amount of dust accumulation on the outer surface of the filter bag 16 and affect the filtering quality of the gas.
