[0001] This utility model belongs to the field of fertilizer production technology, specifically an environmentally friendly waste gas treatment device for fertilizer production. Background Technology

[0002] Chemical fertilizers, also known as inorganic fertilizers, are fertilizers containing one or more nutrients needed for crop growth, produced using chemical and physical methods. They include nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micronutrient fertilizers, and compound fertilizers. They share some common characteristics: simple composition and high nutrient content; rapid and potent effects; some fertilizers exhibit acid-base reactions; generally do not contain organic matter and do not improve soil structure. There are many types of chemical fertilizers, with significant differences in properties and application methods. The waste gases generated during the production of chemical fertilizers, if directly emitted into the air, will pollute the air and disrupt the ecological balance; therefore, waste gas treatment is necessary.

[0003] Currently, exhaust gas is generally filtered through a filter screen, which is mostly fixed with bolts. This means that cleaning the filter screen requires operating multiple bolts, making it quite cumbersome. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an environmentally friendly waste gas treatment device for fertilizer production, which effectively solves the problem of the inconvenience of quickly disassembling and cleaning the filter screen.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly waste gas treatment device for fertilizer production, comprising a treatment box, an air inlet pipe fixedly connected to the outside of the treatment box, an air outlet pipe fixedly connected to the bottom of the treatment box, a filter mechanism on the treatment box, and a purification mechanism on the filter mechanism.

[0006] The filtration mechanism includes a support frame fixed inside the treatment box, a filter frame placed on top of the support frame, a U-shaped plate fixedly connected to the top of the filter frame, a top plate above the treatment box, a top sealing ring fixedly connected to the bottom of the top plate that fits against the top of the treatment box, a limiting plate fixedly connected to the bottom of the top plate, a limiting groove provided on the top of the U-shaped plate, and the limiting plate inserted into the limiting groove.

[0008] Preferably, a sleeve block is fixedly sleeved on the outer side of the L-shaped round rod, a screw is rotatably connected to the bottom of the sleeve block, a drive shaft is fixedly connected to the bottom end of the screw, the bottom end of the drive shaft passes through the side plate and is fixedly connected to a turntable, a threaded sleeve is threaded onto the outer side of the screw, and a lifting plate is fixed to the outer side of the threaded sleeve.

[0009] Preferably, the purification mechanism includes a mounting frame located inside the treatment box, an activated carbon layer on the inner side of the mounting frame, the activated carbon layer being located below the support frame, an opening on the side of the treatment box away from the air inlet pipe, and a side block fixedly connected to one side of the mounting frame located inside the opening.

[0010] Preferably, a U-shaped rod is fixedly connected to the outside of the processing box, and an installation plate is movably sleeved on the outside of the U-shaped rod. A side sealing ring and an insert plate are fixedly connected to the side of the installation plate near the processing box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model can filter exhaust gas by setting a filter frame inside the treatment box. The top plate can be raised by the cooperation between the turntable, drive shaft, screw, screw sleeve, lifting plate, L-shaped round rod and connecting frame, so that the limiting plate can be released from the limiting groove to release the fixing effect on the filter frame, thereby making it easy to remove the filter frame from the inside of the treatment box for cleaning.

[0014] 2. This novel design effectively adsorbs harmful gases in waste gas by setting an activated carbon layer inside the treatment chamber, thus purifying the waste gas. The cooperation between the turntable, drive shaft, screw, screw sleeve, lifting plate, and L-shaped round rod facilitates the upward sliding of the guide plate along the guide rod. The cooperation between the movable rod, side frame, mounting plate, and U-shaped round rod facilitates the removal of the insert plate from the opening and its separation from the side block. This allows the mounting frame to be pulled out of the treatment chamber, making it easy to replace the activated carbon layer. Attached Figure Description

[0027] Specifically, by Figure 3-5 The filter mechanism 2 includes a support frame 201 fixed inside the treatment box 1. A filter frame 202 is placed on top of the support frame 201. The connection between the air inlet pipe 6 and the treatment box 1 is located above the filter frame 202, facilitating the filtration of exhaust gas through the filter frame 202. A U-shaped plate 205 is fixedly connected to the top of the filter frame 202. A top plate 203 is provided above the treatment box 1. A top sealing ring 208 that fits against the top of the treatment box 1 is fixedly connected to the bottom of the top plate 203. A limiting plate 207 is fixedly connected to the bottom of the top plate 203. A limiting groove 206 is provided on the top of the U-shaped plate 205, and the limiting plate 207 is inserted into the limiting groove 206. A side plate 209 is fixedly connected to the outside of the treatment box 1. An L-shaped round rod 2016 is fixedly connected between the top of the side plate 209 and the outer side of the processing box 1. A lifting plate 204 is movably sleeved on the outer side of the L-shaped round rod 2016. A connecting frame 2014 is fixedly connected between the top of the lifting plate 204 and the outer side of the top plate 203. A sleeve block 2015 is fixedly sleeved on the outer side of the L-shaped round rod 2016. A screw rod 2013 is rotatably connected to the bottom of the sleeve block 2015. A drive shaft 2011 is fixedly connected to the bottom end of the screw rod 2013. The bottom end of the drive shaft 2011 passes through the side plate 209 and is fixedly connected to a turntable 2010. A screw sleeve 2012 is threadedly sleeved on the outer side of the screw rod 2013. The lifting plate 204 is fixed to the outer side of the screw sleeve 2012.

[0028] In use, the filter frame 202 is first fixed inside the support frame 201 to filter the exhaust gas entering the treatment box 1. When the filter frame 202 needs to be cleaned, the turntable 2010 is rotated to drive the drive shaft 2011 to rotate, which in turn drives the screw 2013 to rotate. The screw sleeve 2012 drives the lifting plate 204 to slide upward along the L-shaped round rod 2016. Then, the connecting frame 2014 drives the top plate 203 to move upward. At the same time, the limiting plate 207 rises and moves out of the limiting groove 206, releasing the limiting effect on the filter frame 202. Then, the filter frame 202 is taken out from the inside of the treatment box 1, and finally, the filter frame 202 is quickly cleaned.

[0029] Specifically, by Figure 6-7The purification mechanism 3 includes a mounting frame 301 located inside the treatment box 1. An activated carbon layer 302 is provided on the inner side of the mounting frame 301, located below the support frame 201. An opening 4 is provided on the side of the treatment box 1 away from the air inlet pipe 6. One side of the mounting frame 301 is located within the opening 4 and is fixedly connected to a side block 309. A U-shaped rod 305 is fixedly connected to the outer side of the treatment box 1. A mounting plate 303 is movably sleeved on the outer side of the U-shaped rod 305. A side sealing ring 3011 and an insert plate 3010 are fixedly connected to the side of the mounting plate 303 closest to the treatment box 1. 010 is inserted into the opening 4 and abuts against the side block 309. The side sealing ring 3011 is fixed to the outside of the insert plate 3010 and fits against the outside of the processing box 1. The outside of the processing box 1 is fixedly connected to the guide rod 308 located below the mounting plate 303. The outside of the guide rod 308 is movably sleeved with the guide plate 306. The guide plate 306 is fixed to the outside of the lifting plate 204. The outside of the guide plate 306 is rotatably connected to the movable rod 307. The side frame 304 is fixedly connected to the side of the mounting plate 303 away from the processing box 1. The top of the movable rod 307 is rotatably connected to the bottom of the side frame 304.

[0030] In use, an activated carbon layer 302 is first set below the filter frame 202 to effectively adsorb harmful gases in the exhaust gas and purify it. When the lifting plate 204 slides upward along the L-shaped rod 2016, it drives the guide plate 306 to slide upward along the guide rod 308. Then, the side frame 304 is moved by the movable rod 307. At the same time, the mounting plate 303 slides along the U-shaped rod 305 and drives the insert plate 3010 to move out of the opening 4 and separate from the side block 309, thus releasing the restriction effect on the mounting frame 301. Then, the side block 309 is pulled to remove the mounting frame 301 from the inside of the treatment box 1. Finally, the activated carbon layer 302 is replaced.
