Description

Technical Field

[0001] This utility model relates to the field of straw carbonization processing technology, specifically to a tail gas purification and treatment device for straw carbonization processing. Background Technology

[0002] Currently, biomass carbonization is mainly used for household purposes such as barbecuing and heating. It requires mechanically compressing chopped biomass raw materials into rods or blocks before carbonizing them in a carbonization furnace. However, during the carbonization process, only about 30% of the material is eventually converted into biochar, while about 30% is discharged in gaseous form. Existing devices cannot effectively treat the exhaust gas, resulting in flammable exhaust gases that pollute the environment.

[0003] According to a publicized biomass carbonization furnace tail gas treatment device (publication number: CN220149493U), the above application utilizes the combined action of a sleeve, filter chamber, fixing block, activated carbon filter, cover plate, and sleeve two to effectively filter and remove particulate matter and harmful gases from the tail gas, demonstrating good practicality. First, by connecting the sleeve and sleeve two to the connecting pipe and the gas outlet respectively, when the cooled tail gas enters the filter chamber through the sleeve and passes through the activated carbon filter, the activated carbon filter can adsorb particulate matter and harmful gases in the tail gas. Then, the filtered gas is discharged through sleeve two. After the operation is completed, the activated carbon filter can be removed from the fixing block by opening the cover plate for cleaning.

[0004] However, in the aforementioned applications, the filtration process must be interrupted when cleaning or replacing the filter, which reduces the efficiency of exhaust gas treatment. Especially in high-load continuous operation scenarios, frequent shutdowns for maintenance will seriously affect production efficiency and cannot meet the actual needs of large-scale biomass carbonization production. Utility Model Content

[0005] The purpose of this invention is to provide a tail gas purification and treatment device for straw carbonization processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tail gas purification and treatment device for straw carbonization processing, comprising a box body, wherein a partition is fixed to the inner wall of the box body, and movable components and limiting components are provided inside and on the surface of the box body and the partition.

[0007] The active components include:

[0008] The rocker arm is used to drive the screw to rotate synchronously.

[0009] Threaded blocks are used to synchronously drive the rack and pinion to move synchronously.

[0010] The round plate is used to replace the air intake when it is fitted with a leak hole.

[0011] Preferably, the rocker arm is rotatably connected to the left side surface of the housing. The output shaft of the rocker arm passes through the housing and is rotatably connected to the housing. A screw is rotatably connected to the inner wall of the housing. The screw passes through a partition and is connected to the partition via a sealed bearing. A threaded block is slidably connected to the inner wall of the housing. The screw passes through the threaded block and is threadedly connected to the threaded block. A rack is fixed to the end of the threaded block away from the screw. A circular plate is rotatably connected to the bottom of the inner wall of the housing. The outer surface of the circular plate has drainage holes. A gear is fixed to the top of the circular plate. The rack meshes with the gear. When the rocker arm is rotated, the screw rotates synchronously, causing the threaded block and rack to move closer together, thereby driving the gear and the circular plate to rotate synchronously. At this time, one set of drainage holes aligns with the outlet of the three-way pipe, while the other set is offset, thereby changing the direction of exhaust gas flow. In this way, unused filter plates can continue to filter, while the sealed door corresponding to the filter plates that need to be replaced can be opened for replacement. The entire process does not require machine downtime, significantly improving work efficiency.

[0012] Preferably, the limiting component includes a sliding groove located on the side of the rocker arm near the housing. A movable column is slidably connected to the inner wall of the sliding groove. A spring is fixed to the outer surface of the movable column. A stabilizing groove is formed on the left outer surface of the housing. Insertion holes are formed on the outer surfaces of both the movable column and the rocker arm. Insertion rods are inserted into the insertion holes. A connecting rope is fixed to the end of the insertion rod away from the insertion hole. A fixing plate is fixed to the outer surface of the rocker arm. A fixing plate is fixed to the surface of the fixing plate. A spring is fixed to the side of the fixing plate near the insertion rod. A clamping plate is fixed to the end of the spring is away from the fixing plate. When the rocker arm rotates, the surface of the movable column contacts the inner wall of the stabilizing groove and compresses the spring. When the movable column aligns with the stabilizing groove, the spring releases, causing the movable column to engage in the stabilizing groove, ensuring normal rotation of the rocker arm. After the filter plate is replaced, inserting the insertion rod restricts the movement of the movable column and the rocker arm. At the same time, the clamping plate fixes the insertion rod to prevent it from falling off, avoiding accidental rotation of the rocker arm that could affect the entry of exhaust gas.

[0013] Preferably, the screw is provided with two opposite threads, so that when rotated, the threaded block and the rack can move closer or further away from each other synchronously.

[0014] Preferably, the top of the box is provided with an air outlet, the bottom of the box is provided with a three-way pipe, the outer surface of the box is provided with a sealing door, the partition is fixed with a connecting frame to the surface and inner wall of the box, the connecting frame is inserted with a filter plate, and the sealing door, the connecting frame, and the filter plate are provided in two sets for easy filtration and replacement.

[0015] Preferably, the threaded block, rack, gear, and circular plate are each provided in two sets, and the perforations on the surface of the circular plate are staggered to facilitate the alternating entry of exhaust gas into the housing.

[0016] Preferably, a rubber pad is fixed to the side of the clamp away from the second spring, and the end of the movable column away from the first spring is set in an arc shape. The rubber pad increases the friction and prevents the insertion rod from slipping. The arc-shaped surface of the movable column abuts against the inner wall of the stabilizing groove, which allows the movable column to move into the sliding groove.

[0017] Compared with the prior art, this utility model provides a tail gas purification and treatment device for straw carbonization processing, which has the following beneficial effects:

[0018] 1. This exhaust gas purification equipment for straw carbonization processes utilizes movable components. When filter plates need replacement, rotating the rocker arm causes the screw to rotate synchronously, bringing the threaded block and rack closer together. This drives the gear and circular plate to rotate synchronously, aligning one set of perforations with the outlet of the tee pipe, while the other set is offset, changing the direction of exhaust gas flow. Unused filter plates can continue filtering, while the sealing door corresponding to the filter plate requiring replacement can be opened for replacement. The entire process requires no machine downtime, improving work efficiency and avoiding impact on production efficiency.

[0019] 2. The exhaust gas purification equipment for straw carbonization processing uses a limiting component. When the replacement is completed, inserting the plug rod into the plug hole will limit the movement of the movable column and rocker arm, which can prevent external accidental contact from causing displacement and affecting the entry of exhaust gas.

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: a tail gas purification treatment device for straw carbonization processing, including a box 1, a partition 5 fixed on the inner wall of the box 1, and movable components 8 and limiting components 9 provided inside and on the surface of the box 1 and the partition 5; the movable components 8 include: rocker arm 80, screw 81, threaded block 82, rack 83, gear 84, circular plate 85, leakage hole 86, and abutment rod 87.

[0027] A rocker arm 80 is rotatably connected to the left side surface of the housing 1. The output shaft of the rocker arm 80 passes through the housing 1 and is rotatably connected to the housing 1. A screw 81 is rotatably connected to the inner wall of the housing 1. The screw 81 passes through the partition 5 and is connected to the partition 5 through a sealed bearing. A threaded block 82 is slidably connected to the inner wall of the housing 1. The screw 81 passes through the threaded block 82 and is threadedly connected to the threaded block 82. A rack 83 is fixed to the end of the threaded block 82 away from the screw 81. A circular plate 85 is rotatably connected to the bottom of the inner wall of the housing 1. A perforation 86 is opened on the outer surface of the circular plate 85. A gear 84 is fixed to the top of the circular plate 85. The rack 83 and the gear 84 are connected to each other. 4. Engagement: The screw 81 has two opposite threads. The threaded block 82, rack 83, gear 84, and circular plate 85 are each equipped with two sets of threads. The perforations 86 on the surface of the circular plate 85 are staggered. When the rocker arm 80 is rotated, the screw 81 rotates synchronously, and the threaded block 82 and rack 83 move closer to each other, driving the gear 84 and circular plate 85 to rotate synchronously. At this time, one set of perforations 86 is parallel to the outlet of the three-way pipe 4, and the other set of perforations 86 is staggered with the three-way pipe 4, which can change the direction of the exhaust gas entering. At this time, the other set of filter plates 7 performs filtration work. The sealing door 3 corresponding to the filter plate 7 that needs to be replaced can be opened, and the filter plate 7 can be pulled out for replacement without stopping the filtration work, thus improving processing efficiency.

[0028] The limiting component 9 includes a slide groove 90, which is located on the side of the rocker arm 80 near the housing 1. A movable column 91 is slidably connected to the inner wall of the slide groove 90. A spring 92 is fixed to the outer surface of the movable column 91. A stabilizing groove 93 is provided on the outer surface of the left side of the housing 1. Insertion holes 94 are provided on the outer surfaces of both the movable column 91 and the rocker arm 80. A rod 95 is inserted into the insertion hole 94. A connecting rope 96 is fixed to the end of the rod 95 away from the insertion hole 94. A fixing plate 97 is fixed to the outer surface of the rocker arm 80. A fixing plate 98 is fixed to the surface of the fixing plate 97. A spring 98 is fixed to the side of the fixing plate 97 near the rod 95. A clamping plate 99 is fixed to the end of the spring 98 away from the fixing plate 97. A rubber pad is fixed on the side of the movable column 91 away from the spring 92. The end of the movable column 91 away from the spring 92 is set in an arc shape. When the rocker arm 80 rotates, the surface of the movable column 91 abuts against the inner wall of the stabilizing groove 93, and the spring 92 is compressed. When the position of the movable column 91 is parallel to the stabilizing groove 93, the spring 92 is released, and the movable column 91 enters the stabilizing groove 93 without affecting the normal rotation of the rocker arm 80. When the filter plate 7 is replaced, the insertion rod 95 is inserted into the insertion hole 94 to limit the movable column 91, and then limit the rocker arm 80 synchronously. The clamping plate 99 clamps the insertion rod 95 to prevent the insertion rod 95 from slipping, thus preventing the rocker arm 80 from rotating due to external accidental contact, which would affect the entry of exhaust gas.

[0029] The top of the box 1 is provided with an air outlet 2, the bottom of the box 1 is provided with a three-way pipe 4, the outer surface of the box 1 is provided with a sealing door 3, the partition 5 is fixed with a connecting frame 6 on the surface and inner wall of the box 1, and a filter plate 7 is inserted into the inside of the connecting frame 6. The sealing door 3, the connecting frame 6 and the filter plate 7 are provided in two sets to facilitate filtration and replacement.

[0030] When the exhaust gas from carbonization needs to be purified and filtered, the three-way pipe 4 is connected to the exhaust port of the carbonization furnace. The exhaust gas then enters the housing 1 through the three-way pipe 4 and the leakage hole 86, is filtered by the filter plate 7, and is discharged through the exhaust port 2. When the filter plate 7 needs to be replaced after prolonged use, the insertion rod 95 is pulled out of the insertion hole 94, releasing the restriction on the movable column 91. The rocker arm 80 can then be rotated normally. The rocker arm 80 drives the screw 81 to rotate synchronously, causing the threaded block 82 and the rack 83 to move closer together, which in turn drives the gear 84 and the circular plate 85 to rotate synchronously. When the surface of the contact rod 87 contacts the surface of the partition plate 5, the gear 84 rotates 180°, causing the circular plate 85 to rotate in the opposite direction. At this point, one set of leakage holes 86 is parallel to the outlet of the three-way pipe 4, while the other set of leakage holes 86 is staggered with the three-way pipe 4, thus changing the exhaust gas intake. In the direction of inflow, another set of filter plates 7 is performing filtration. The sealing door 3 corresponding to the filter plate 7 that needs replacement can be opened, and the filter plate 7 can be pulled out for replacement without stopping the filtration process, improving processing efficiency. Simultaneously, when the rocker arm 80 rotates, the surface of the movable column 91 contacts the inner wall of the stabilizing groove 93, compressing the spring 92. When the movable column 91 is parallel to the stabilizing groove 93, the spring 92 releases, allowing the movable column 91 to enter the stabilizing groove 93 without affecting the normal rotation of the rocker arm 80. When the filter plate 7 is replaced, the insertion rod 95 is inserted into the insertion hole 94 to limit the movable column 91, thereby simultaneously limiting the rocker arm 80. At the same time, the spring 98, in conjunction with the clamping plate 99, clamps the insertion rod 95. The rubber pad increases friction, preventing the insertion rod 95 from slipping, thus preventing accidental external contact with the rocker arm 80 and its rotation, which could affect the entry of exhaust gas.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
