Description

Technical Field

[0001] This utility model relates to the field of pulse dust collector technology, specifically to a pulse dust collector for pesticide processing. Background Technology

[0002] During pesticide processing, a large amount of waste gas containing pesticide dust, particles, and volatile organic compounds is generated. Direct emission of this gas not only causes severe air pollution but also poses a significant threat to the health of operators. Furthermore, dust accumulation on equipment within the production environment can reduce its operational efficiency. Therefore, pulse jet dust collectors, as key environmental protection and production auxiliary equipment, are widely used in the exhaust gas treatment stage of pesticide processing production lines. Their core function is to filter and retain dust and impurities in the waste gas through internal filter bags, ensuring that the emitted gas meets environmental standards and guaranteeing a clean production environment and stable equipment operation.

[0003] In existing technologies, dust containing active pesticide ingredients generated during processes such as mixing and crushing needs to be filtered by filter bags in pulse dust collectors to meet emission standards, ensure production safety and environmental cleanliness. However, the filter bags need to be disassembled and maintained regularly due to the sticky and easily solidified nature of pesticide dust.

[0004] However, there are some drawbacks: the filter bags are mostly fixed to the dust collector tube sheet by bolts, but this connection is inconvenient to disassemble. The dense arrangement of filter bags inside the equipment makes the operating space narrow, and it is difficult to exert force with tools such as wrenches. At the same time, it takes a long time to remove the bolts one by one, which is not convenient for staff to disassemble and replace individual filter bags. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a pulse dust collector for pesticide processing, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a pulse dust collector for pesticide processing; it includes a lower housing, an upper housing fixedly connected to the top of the lower housing via a flange, an air inlet fixedly connected to the right side of the lower housing, an air outlet fixedly connected to the left side of the upper housing, an ash discharge valve provided at the bottom of the lower housing, multiple sets of filter bags slidably connected inside the lower housing, and a connecting assembly provided on the lower housing, the lower housing being connected to the filter bags via the connecting assembly; The connecting assembly includes two sets of sockets fixedly connected to the lower housing surfaces on both sides of the filter bag. A fixing ring is fixedly connected to the top of the filter bag, and two sets of inserts are fixedly connected to the top of the fixing ring. The two sets of inserts are slidably connected to the two sets of sockets.

[0007] Furthermore, a spring is fixedly connected inside the insert block, and a limit block is fixedly connected to the other end of the spring. Two sets of sliding grooves are symmetrically opened on the inner wall of the insert block, and a slider is slidably connected in the sliding groove. The outer end of the slider is fixedly connected to the outer wall of the limit block. A limit groove is opened on the inner wall of the socket corresponding to the outer end surface of the limit block, and the limit groove is slidably connected to the limit block.

[0008] Furthermore, one end of the spring is fixedly connected to the middle position inside the insert block, and the other end of the spring is fixedly connected to the middle position on the inner wall of the limiting block.

[0009] Furthermore, an air supply pipe is connected to the right side of the air inlet via a flange. A limiting component is provided between the air inlet and the air supply pipe. The limiting component includes a movable chamber fixedly connected to the bottom of the air inlet. A lead screw is rotatably connected inside the movable chamber. A transmission block is threaded onto the lead screw. A support frame is fixedly connected to the bottom of the transmission block. Two sets of positioning blocks are symmetrically fixedly connected to the side of the support frame.

[0010] Furthermore, a positioning groove is provided through the air inlet and the air supply pipe on the left side surface of the positioning block. The positioning groove is slidably connected to the positioning block. A handwheel is coaxially fixedly connected to the right side of the lead screw.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1: Reference Figures 1 to 4 This is the first embodiment of the present utility model, which discloses a pulse dust collector for pesticide processing, including a lower housing 1, an upper housing 2 fixedly connected to the top of the lower housing 1 by a flange, an air inlet 3 fixedly connected to the right side of the lower housing 1, an air outlet 4 fixedly connected to the left side of the upper housing 2, an ash discharge valve 5 provided at the bottom of the lower housing 1, multiple sets of filter bags slidably connected inside the lower housing 1, a connecting assembly 7 provided on the lower housing 1, and the lower housing 1 connected to the filter bags through the connecting assembly 7. The connecting assembly 7 includes two sets of sockets 71 fixedly connected to the surfaces of the lower housing 1 on both sides of the filter bag. A fixing ring 72 is fixedly connected to the top of the filter bag. Two sets of inserts 73 are fixedly connected to the top of the fixing ring 72. The two sets of inserts 73 are slidably connected to the two sets of sockets 71. A spring 74 is fixedly connected inside the insert 73. A limit block 75 is fixedly connected to the other end of the spring 74. Two sets of sliding grooves 76 are symmetrically opened on the inner wall of the insert 73. A slider 77 is slidably connected inside the sliding groove 76. The outer end of the slider 77 is fixedly connected to the outer wall of the limit block 75. A limit groove 78 is opened on the inner wall of the socket 71 corresponding to the outer end surface of the limit block 75. The limit groove 78 is slidably connected to the limit block 75.

[0020] One end of the spring 74 is fixedly connected to the middle position inside the insert block 73, and the other end of the spring 74 is fixedly connected to the middle position on the inner wall of the limiting block 75. This allows the spring 74 to evenly output its restoring force to the limiting block 75 when the limiting block 75 squeezes the spring 74, thereby enabling the limiting block 75 to stably return to its original position and slide within the insert block 73, and pass through the limiting groove 78, thus achieving the purpose of installing the filter bag.

[0021] In use, firstly, slide the limiting block 75 from the limiting groove 78 into the insert block 73, causing the limiting block 75 to drive the slider 77 to slide in the sliding groove 76, and causing the limiting block 75 to compress the spring 74. Then, the fixing ring 72 drives the insert block 73 to rotate out of the socket 71. Next, the fixing ring 72 drives the filter bag to slide out of the lower housing 1, thereby achieving the purpose of quickly disassembling a single filter bag. When installation is required, the fixing ring 72 drives the filter bag to slide into the lower housing 1. Then, rotate the fixing ring 72, and the fixing ring 72 drives the insert block 73 to rotate into the socket 71, and align the limiting block 75 with the limiting groove 78. Then, the restoring force of the spring 74 pushes the limiting block 75 to return to its original position and slide in the insert block 73, and the limiting block 75 passes through the limiting groove 78, thereby achieving the purpose of installing a new filter bag.

[0022] An air inlet 3 is connected to an air supply duct 6 via a flange on its right side. A limit assembly 8 is installed between the air inlet 3 and the air supply duct 6. The limit assembly 8 includes a movable chamber 81 fixedly connected to the bottom of the air inlet 3. A lead screw 82 is rotatably connected inside the movable chamber 81. A transmission block 83 is threaded onto the lead screw 82. A support frame 84 is fixedly connected to the bottom of the transmission block 83. Two sets of positioning blocks 85 are symmetrically fixedly connected to the side of the support frame 84. A positioning groove 86 is opened through the air inlet 3 and the air supply duct 6 on the left side surface of the positioning block 85. The block 85 is rectangular in shape, and the positioning groove 86 is a through hole that fits the positioning block 85. This allows the positioning groove 86 and the positioning block 85 to fit together on multiple sides, thereby achieving the purpose of positioning the air supply pipe 6 and the air inlet 3. This prevents misalignment of the threaded holes in the air inlet 3 and the air supply pipe 6. The positioning groove 86 and the positioning block 85 are slidably connected. A handwheel 87 is coaxially fixedly connected to the right side of the lead screw 82. A pulser 9 is provided on the right side of the lower housing 1. Multiple sets of pulse tubes 91 are provided on the inner wall of the upper housing 2, which are directly opposite the filter bag positions.

[0023] The support frame 84 has the same curvature as the air inlet 3 and the outer wall of the air duct 6. The outer wall of the support frame 84 fits against the outer wall of the air inlet 3 and the outer wall of the air duct 6, which enables the support frame 84 to support the air duct 6. This eliminates the need for workers to hold the air duct 6 when installing it, thus relieving the pressure on workers' arms when holding the air duct 6.

[0024] In use, first place the air duct 6 in the support frame 84 and align the positioning groove 86 with the positioning block 85. Then, turn the handwheel 87 to drive the lead screw 82 to rotate in the movable chamber 81, and the lead screw 82 will drive the transmission block 83 to move in the movable chamber 81. Then, the support frame 84 will drive the positioning block 85 to slide into the positioning groove 86 until the positioning block 85 pushes the air duct 6 to fit with the air inlet 3, thereby achieving the purpose of positioning the air inlet 3 and the internal threaded hole of the air duct 6, so as to facilitate the staff to quickly connect the air inlet 3 and the air duct 6.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
