Description

Technical Field

[0001] This utility model belongs to the field of bean processing technology, specifically a waste gas purification device for a bean processing production line. Background Technology

[0002] Legumes are seeds or fruits of plants belonging to the legume family in botany. They have extremely high economic and nutritional value and are an important part of human diet and agricultural production. Legume processing production lines generate waste gas during processes such as crushing, roasting, and drying. Waste gas purification devices are environmental protection equipment that treat such waste gas through physical, chemical, or biological means to make it meet emission standards.

[0003] Currently, most technologies for treating exhaust gas from soybean processing rely on a single filter screen. Traditional filters can only remove larger dust particles through physical interception, and their purification effect on submicron-sized oil mist particles, water-soluble organic matter, and odor substances is minimal.

[0024] Example 1, by Figure 1-5This utility model relates to a waste gas purification device for a bean processing production line, comprising a main housing 1, a water inlet pipe 13 fixedly connected to the top of the main housing 1, the water inlet pipe 13 having a sealing plug to facilitate the addition of water into the main housing 1, a guide bucket 5 fixedly connected to the bottom of the main housing 1, a drain pipe 4 fixedly connected to the bottom end of the guide bucket 5, and a valve on the drain pipe 4, a fixing mechanism 2 on the outside of the main housing 1, an annular pipe 7 inside the main housing 1, two support blocks 27 symmetrically fixedly connected between the annular pipe 7 and the main housing 1, multiple air outlets 30 at equal angles at the bottom of the annular pipe 7, and a fixed mechanism 2 on the outside of the annular pipe 7. An air inlet pipe 14 is fixedly connected to the main housing 1. The end of the air inlet pipe 14 away from the annular pipe 7 extends to the outside of the main housing 1. Inside the main housing 1, there is a filter frame 6 located below the annular pipe 7. Inside the annular pipe 7, there is a hollow disc 26. The bottom of the hollow disc 26 has multiple spray holes 28. A connecting pipe 11 is fixedly connected to the outside of the main housing 1. The end of the connecting pipe 11 away from the main housing 1 is fixedly connected to the purification box 10. An air outlet pipe 8 is fixedly connected to the outside of the purification box 10 near the bottom. Inside the purification box 10, from top to bottom, there are two supports 24 and one support 21. Filter screens 23 and supports 21 are respectively installed on the two supports 24 and one support 21. 1. The connection between the connecting pipe 11 and the purification box 10 is located above the bracket 24, and the connection between the outlet pipe 8 and the purification box 10 is located below the bracket 21. This facilitates the entry of gas from the main box 1 into the purification box 10 through the connecting pipe 11, where it is purified by the filter screen 23 and the activated carbon layer 22. A positioning block 16 is fixedly connected to the outside of the main box 1, and a mounting plate 3 is fixedly connected to the outside of the filter frame 6. The mounting plate 3 is fitted onto the outside of the positioning block 16, and a sealing ring 17 that fits against the outer wall of the main box 1 is fixedly connected to the outside of the mounting plate 3. By setting the sealing ring 17, the gas can be kept clean. To ensure the airtightness of the main housing 1, a mounting plate 29 is fixedly connected between bracket 1 21 and bracket 2 24. The mounting plate 29 is located on the outside of the purification box 10. A sealing ring 20 that fits against the outer wall of the purification box 10 is fixedly connected to the outside of the mounting plate 29. By setting the sealing ring 20, the airtightness of the purification box 10 can be guaranteed. A positioning block 2 18 is fixedly connected to the outside of the purification box 10.

A water supply pipe 25 is fixedly connected between the water pump 12 and the hollow plate 26. A water suction pipe 29 is fixedly connected between the water pump 12 and the drain pipe 4.

[0025] In operation, the exhaust gas is first introduced into the inlet pipe 14, and simultaneously discharged through the annular pipe 7 and from each outlet 30, so that the exhaust gas enters the main chamber 1 evenly. Then, the water pump 12 is started, and water is drawn from the main chamber 1 through the water suction pipe 29, the drain pipe 4, and the guide bucket 5, so that the water enters the hollow plate 26 through the water supply pipe 25 and is sprayed out from each spray hole 28 to achieve dust suppression by spraying the exhaust gas. The filter frame 6 filters the impurities produced by spraying, which enables the recycling of water resources. After dust suppression, the exhaust gas enters the purification box 10 through the connecting pipe 11, and is filtered again by the filter screen 23. At the same time, the activated carbon layer 22 adsorbs the odor, and finally the exhaust gas is thoroughly purified.

[0026] Specifically, by Figure 6 As shown, the fixing mechanism 2 includes a mounting bracket 201 fixed to the outside of the main housing 1. An L-shaped round rod 205 is fixedly connected between the top of the mounting bracket 201 and the main housing 1. A two-way screw rod 203 is rotatably connected to the top of the mounting bracket 201. A handwheel 204 is fixedly connected to the top of the two-way screw rod 203. Two screw nuts 202 are symmetrically threaded on the outside of the two-way screw rod 203. Both screw nuts 202 are movably sleeved on the outside of the L-shaped round rod 205. Positioning rod 1 206 and positioning rod 207 are fixedly connected to the outside of the two screw nuts 202 respectively. A positioning ring 15 is fixedly connected to the top of the mounting plate 1 3. Positioning rod 207 is inserted into positioning ring 15. A positioning ring 29 is fixedly connected to the bottom of the mounting plate 2 9. Positioning rod 1 206 is inserted into positioning ring 2 19.

[0027] In use, first rotate the handwheel 204 to drive the bidirectional lead screw 203 to rotate, and cause both lead nuts 202 to slide along the L-shaped round rod 205. At the same time, positioning rod one 206 and positioning rod two 207 move closer to each other until positioning rod two 207 is removed from positioning ring one 15, releasing the fixation on mounting plate one 3. The filter frame 6 can then be disassembled and cleaned. Simultaneously, positioning rod one 206 is removed from positioning ring two 19, releasing the fixation on mounting plate two 9. The filter screen 23 and activated carbon layer 22 can then be disassembled and replaced.
