Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology, and more specifically, to a dust treatment device. Background Technology

[0002] In wastewater treatment plants, phosphorus-containing sludge is a common byproduct, primarily originating from phosphorus-rich sludge formed during biological or chemical phosphorus removal processes. After processing through wet grinding, neutralization, and solid-liquid separation, phosphorus-containing sludge produces iron (zinc) phosphate solids. To achieve phosphorus recovery, these solids need to be ground and sieved. Currently, cyclone separators are commonly used to collect the sieved powder. Cyclone separators collect most of the iron (zinc) phosphate particles at the bottom, while a smaller portion is discharged through the upper pipe. Therefore, the exhaust air from the cyclone separator contains dust, requiring a pulse jet dust collector connected to the upper pipe for purification.

[0003] Existing pulse jet dust collectors typically include an air tank, a blowpipe, and an electromagnetic pulse valve. The air tank stores compressed air, and the electromagnetic pulse valve controls the instantaneous release of the compressed air. The released compressed air is then sprayed into the filter bags through the blowpipe for dust removal. However, to avoid the high-pressure airflow directly impacting the inner wall of the filter bag and causing localized wear or tear, the existing blowpipe is usually located at the top of the filter bag. Due to the length of the filter bag, the bottom of the filter bag is far from the blowpipe, which prevents the compressed airflow entering the filter bag from cleaning the dust at the bottom. As a result, dust remains attached to the bottom surface of the filter bag, affecting subsequent use. Therefore, improvements are needed. Summary of the Invention

Detailed Implementation

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0023] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0024] Please see Figures 1-7A dust treatment device in this embodiment includes a housing 100, a dust removal chamber inside the housing 100, a partition 210 fixedly connected inside the dust removal chamber, the partition 210 being used to divide the dust removal chamber into an upper chamber and a lower chamber; a plurality of filter bags 240 are provided in the lower chamber, the filter bags 240 are open at the upper end and vertically arranged, the upper opening of the filter bags 240 is fixedly connected to the partition 210 and passes through the partition 210 to communicate with the upper chamber, a discharge hopper 104 is fixedly connected to the bottom end of the lower chamber, a fixing frame 220 is fixedly connected inside the lower chamber, the bottom ends of the filter bags 240 are all fixedly installed on the fixing frame 220, a first striking component is provided outside the housing 100, the first striking component is used to strike the side wall of the discharge hopper 104, a second striking component is provided inside the lower chamber, the second striking component is used to strike the fixing frame 220.

[0025] In this embodiment, an air inlet pipe 250 and an air outlet pipe 102 are fixedly connected to the outer side of the outer shell 100. The air inlet pipe 250 connects to the lower cavity, and the air outlet pipe 102 connects to the upper cavity. The discharge hopper 104 is equipped with an openable and closable ash discharge valve. In actual use, the outer shell 100 is installed on the outer shell of the cyclone collector through a mounting bracket, and the air inlet pipe 250 is connected to the air outlet pipe of the cyclone collector. When treating the waste gas, firstly, the ash discharge valve is closed, and at the same time, the airflow containing dust is allowed to enter the lower cavity through the air inlet pipe 250. The filter bag 240 can intercept the dust in the waste gas, so that the waste gas can only enter the upper cavity through the filter bag 240 and finally be discharged from the air outlet pipe 102 to achieve the treatment of waste gas. An air tank 120 is fixedly connected to the outer wall of the outer casing 100. The air tank 120 stores compressed gas. Multiple air supply pipes are fixedly connected to the upper cavity above the partition 210, and these pipes connect to the air tank 120. Multiple blowpipes and nozzles are fixedly connected to the air supply pipes, which are located above the filter bag 240. An electromagnetic pulse valve is fixedly connected inside each blowpipe. When a large amount of dust accumulates on the outer surface of the filter bag 240, the electromagnetic pulse valve operates, causing compressed gas to be injected into the filter bag 240, thereby filtration. Dust on the outer surface of bag 240 is detached. At the same time, the second striking component is activated to strike the fixing frame 220, causing the bottom of filter bag 240 to vibrate and promote the detachment of dust on the outer wall of filter bag 240 near the bottom. The first striking component is activated to strike the side wall of discharge hopper 104, causing the dust and iron phosphate (zinc) particles accumulated on the side wall of discharge hopper 104 to vibrate and finally fall to the bottom of discharge hopper 104. At this time, the ash discharge valve is opened to allow the dust and iron phosphate (zinc) particles to be discharged from the lower opening of discharge hopper 104.

[0026] Combination Figures 1-3As shown, in this embodiment, the first striking component includes a first turntable 230 disposed opposite to the outer casing 100. A connecting post 231 is fixedly connected to the first turntable 230, and a connecting plate 232 is rotatably connected to the connecting post 231. A movable moving plate 110 is disposed opposite to the outer casing 100. A plurality of impact posts 111 are fixedly connected to the side of the moving plate 110 near the discharge hopper 104. A track 300 is fixedly connected to the side wall of the outer casing 100. A connecting rod 310 that can slide within the track 300 is fixedly connected to the side wall opposite to the moving plate 110. A connecting rod 310 is rotatably connected to one side of the connecting plate 232. The rotation of the first turntable 230 is used to drive the connecting rod 310 to reciprocate within the track 300.

[0027] In this embodiment, when the first turntable 230 is in its initial position, the connecting post 231 is located on the side close to the track 300. Since the connecting post 231 is rotatably connected to one end of the connecting plate 232, and the other end of the connecting plate 232 is rotatably connected to the connecting rod 310, when the first turntable 230 rotates, it will drive the connecting post 231 to move away from the track 300. Under the traction of the connecting plate 232 and the limiting effect of the track 300, the moving plate 110 will move towards the outer shell 100. The movement causes the impact column 111 to strike the side wall of the discharge hopper 104, causing the dust accumulated on the inner side wall of the discharge hopper 104 to vibrate and promote its detachment. When the connecting column 231 rotates to a position away from the track 300, the impact column 111 will contact the side wall of the discharge hopper 104. At this time, when the first turntable 230 continues to rotate, the impact column 111 will move away from the discharge hopper 104. The above actions are repeated so that the impact column 111 can repeatedly strike the outer side wall of the discharge hopper 104. It should be noted that the impact columns 111 are arranged in multiple rows on the moving plate 110, and their lengths are different. When the moving plate 110 moves and drives the impact columns 111 to impact the outer wall of the discharge hopper 104, each impact column 111 can fit against the outer side of the discharge hopper 104, and can impact the outer wall of the discharge hopper 104 well.

[0028] Combination Figures 1-5 As shown, in this embodiment, a mounting bracket 600 is fixedly connected to the outer shell 100, and a motor 601 for driving the first turntable 230 to rotate is fixedly connected to the mounting bracket 600.

[0029] In this embodiment, a second turntable 610 is fixedly connected to the output shaft of the motor 601, and the two ends of the connecting post 231 are fixedly connected to the edges of the second turntable 610 and the first turntable 230 respectively, so that a fixed connection is formed between the two. Thus, when the motor 601 starts, it can drive the second turntable 610, the connecting post 231 and the first turntable 230 to rotate.

[0030] Combination Figures 2-7 As shown, in this embodiment, a plurality of protruding columns 510 are fixedly connected to the fixing frame 220. The second striking component includes a fixing plate 730 fixedly connected to the dust removal chamber. A first rotating shaft 720 is rotatably connected to the fixing plate 730 via a bearing. A first striking plate 721 is fixedly connected to the first rotating shaft 721. A second striking plate 722 is rotatably connected to one end of the first striking plate 721. The rotation of the first rotating shaft 720 is used to drive the second striking plate 722 to strike the protruding columns 510.

[0031] In this embodiment, when the first rotating shaft 720 rotates, it can drive the first striking plate 721 and the second striking plate 722 to rotate accordingly. When the second striking plate 722 contacts the protruding column 510, it can cause the protruding column 510, the fixing plate 730 and the bottom of the filter bag 240 to vibrate, thereby promoting the dust to fall off from the outer wall of the filter bag 240 and near the bottom. Specifically, in order to prevent dust detached from the outer wall of the filter bag 240 from accumulating on the fixed frame 220, the fixed frame 220 is provided with multiple strip grooves. Most of the dust can pass through the strip grooves and through the fixed frame 220. Even if a small amount of dust accumulates on the fixed frame 220, the dust can still detach from the fixed frame 220 through the strip grooves during the vibration of the fixed frame 220.

[0032] Combination Figures 2-7 As shown, in this embodiment, a first bevel gear 801 is fixedly connected to the first rotating shaft 720, and a second rotating shaft 700 with one end extending into the dust removal chamber is fixedly connected to the first turntable 230. A second bevel gear 800 is fixedly connected to the second rotating shaft 700. The first bevel gear 801 and the second bevel gear 800 are meshed together. The rotation of the second rotating shaft 700 is used to drive the first rotating shaft 720 to rotate.

[0033] In this embodiment, when the first turntable 230 drives the second rotating shaft 700 to rotate, the first rotating shaft 720 can be rotated under the transmission of the first bevel gear 801 and the second bevel gear 800.

[0034] Combination Figures 6-7 As shown, in this embodiment, a protective cover 731 covering the first bevel gear 801 and the second bevel gear 800 is fixedly connected to the lower side of the fixing plate 730.

[0035] In this embodiment, by setting the protective cover 731, the possibility of the first bevel gear 801 and the second bevel gear 800 coming into contact with the dust in the discharge hopper 104 can be reduced, thereby reducing the impact of dust particles on the transmission between the first bevel gear 801 and the second bevel gear 800.

[0036] Combination Figures 6-7As shown, in this embodiment, a cleaning plate 710 is fixedly connected to the first rotating shaft 720 located on the upper side of the fixed plate 730, and a brush 711 is fixedly connected to the side of the cleaning plate 710 near the fixed plate 730.

[0037] In this embodiment, when the first rotating shaft 720 rotates, it can also drive the cleaning plate 710 and the brush 711 to rotate, brushing away the dust gathered on the upper side of the fixed plate 730, so that the dust on it can be removed and the dust can be prevented from accumulating on the fixed plate 730.

[0038] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
