Without anti-corrosion treatment, corrosion can worsen, impacting their lifespan. A resin-laying device is used for the anti-corrosion lining of the chimney's inner wall. This device typically includes a circular track and a moving trolley. During operation, resin is first applied to the trolley, and then the movable end of a fiberglass fabric is laid onto the resin-coated inner wall of the chimney pipe. A brush roller presses down the movable end of the fiberglass fabric, completing the fiberglass lining process for the chimney pipe.

[0003] Existing chimney anti-corrosion lining equipment can apply resin material to the chimney anti-corrosion lining. However, during the application of resin material, excess resin material may fall off without adhering to the inner wall of the chimney, making it inconvenient to recycle the excess resin material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model collects resin that falls during spraying by installing a recycling mechanism. In existing methods, excess resin often falls off the inner wall of the chimney during the coating process. Therefore, this needs improvement. First, the second assembly plate and the first assembly plate are attached together. Then, the assembly screw is fixed into the assembly screw groove, completing the installation of the recycling box. Next, the attachment of the electric pole moves the recycling box, causing it to adhere to the inner wall of the chimney to be sprayed. Excess resin will then be collected through the recycling box. A triangular inclined plate is installed in the recycling box via a first and second Velcro plate, and an anti-stick layer prevents resin from adhering to the box. When the recycling box is full, it is disassembled, and the resin is poured out using the triangular inclined plate (45° inclination angle), thus preventing excess resin from falling off.

[0015] 2. This utility model purifies the odor generated during resin spraying by installing a purification mechanism. When the resin material is sprayed, it emits a large amount of odor, which affects the working environment. Therefore, it is necessary to reduce the emitted odor and minimize its impact on the working environment. The activated carbon plate is pre-pressed by pushing the fastening block spring, causing the sleeve rod to move within the sleeve, thus moving the activated carbon plate between two sets of fastening blocks. The activated carbon plate then adheres to the outside of multiple sets of exhaust channels. At this point, the fastening blocks are released, allowing the two sets of fastening blocks to reset and fix the position of the activated carbon plate. The adsorption fan then adsorbs the air at the resin spraying location and filters the air through a filter screen. The air is then discharged through the exhaust channels, where the odor is filtered by the activated carbon plate, thereby reducing the odor's impact on the environment. Attached Figure Description

First, a circular track is installed inside the chimney to provide a running track for the paste-spreading trolley 1, ensuring that the paste-spreading trolley 1 can move in a circle along the inner wall of the chimney. Its size and shape are customized according to the diameter and shape of the chimney. Then, the paste-spreading trolley 1 moves on the circular track by wheels 2. The driver's cab 3 is used as a standing area for workers. Then, control panel 4 controls the paste-spreading trolley 1 to move forward. When the work is in progress, the pump 7 operates to deliver the resin from the material box 6 to the spray gun 11. The spray gun 11 is angled by the angle motor 9, and the resin is pre-applied to the inside of the chimney at the corresponding position of the spreading trolley 1 to provide an adhesive base for the subsequent spreading of the fiberglass fabric. Then, the movable end of the fiberglass fabric is manually spread onto the inner wall of the chimney pipe that has been sprayed with resin. Then, the compaction rod 12 operates to drive the compaction frame 13 to move up and down, and the compaction roller 15 compacts the fiberglass fabric, thus performing anti-corrosion work on the inside of the chimney through the fiberglass fabric.

[0028] Please see Figure 2 , Figure 4 and Figure 5The bottom of the spray gun 11 is equipped with a recovery mechanism for collecting resin that falls during spraying. The recovery mechanism includes a bonding pole 16 and a recovery box 19. The bonding pole 16 is located at the bottom of the spray gun 11, and a first assembly plate 17 is installed at the output end of the bonding pole 16. A second assembly plate 18 is installed on the outer wall of the first assembly plate 17, and the recovery box 19 is located on the outer wall of the second assembly plate 18. The outer wall of the second assembly plate 18 is provided with an assembly screw groove 20, and an assembly screw 21 is installed on the outer wall of the first assembly plate 17, with one end of the assembly screw 21 extending into the interior of the second assembly screw groove 20.

The recycling bin 19 is a rectangular concave slot frame, and the fitting slots 22 are provided with two sets and are circular. The first Velcro plate 23 has a rough surface, and the second Velcro plate... Plate 24 has a hook surface, and the tensile strength after the two are bonded together is 6N. Triangular inclined plate 25 is a triangular block, and the outer wall of triangular inclined plate 25 is also provided with an anti-adhesion layer 26. Furthermore, the anti-adhesion layer 26 is provided in all possible contact areas with resin material inside the recycling bin 19. The anti-adhesion layer 26 is made of polytetrafluoroethylene and has a thickness of 50-100µm. Triangular inclined plate 25 is made of 304 stainless steel. Currently, during the plastering process, excess resin material often fails to adhere to the inner wall of the chimney, causing it to fall off. Therefore, this needs to be improved. First, the second assembly plate 18 and the first assembly plate 17 are bonded together, and then the assembly screw 21 is used to fix them. Once the assembly screw groove 20 is in place, the installation of the recycling box 19 is complete. Subsequently, the working of the attached pole 16 drives the recycling box 19 to move, so that the recycling box 19 is in contact with the inner wall of the chimney to be sprayed. When excess resin material falls, it will be collected through the recycling box 19. The triangular inclined plate 25 is installed in the recycling box 19 through the first hook and loop fastener 23 and the second hook and loop fastener 24, and the anti-stick layer 26 is used to prevent resin from adhering to the recycling box 19. When the recycling box 19 is full, the recycling box 19 is disassembled, and the resin material is poured out with the assistance of the triangular inclined plate 25 (tilt angle of 45°), thereby preventing excess resin material from falling.

[0029] Please see Figure 5 , Figure 6 and Figure 7The outer wall of the recycling bin 19 is equipped with a purification mechanism to purify the odor generated during resin spraying. The purification mechanism includes a purification box 27, an adsorption fan 29, and an activated carbon plate 36. The purification box 27 is located on the outer wall of the recycling bin 19, and a filter screen 28 is installed on its outer wall. The adsorption fan 29 is located on the inner wall of the purification box 27, and an exhaust trough 30 is provided on its inner wall. A fixed plate 31 is installed on the outer wall of the purification box 27, and a sleeve 32 is installed at the bottom of the fixed plate 31. A sleeve rod 33 is movably installed on the inner wall of the sleeve 32, and a spring 34 is installed around the outer wall of the sleeve rod 33. A fastening block 35 is installed at the bottom of the sleeve rod 33. The activated carbon plate 36 is located on the outer wall of the fastening block 35. The purification box 27 has a rectangular frame, the filter screen 28 is made of HEPA filter material with a pore size of 0.3 micrometers, the exhaust trough 30 is a rectangular trough, with five sets arranged longitudinally and three rows arranged laterally, with a spacing of 50mm between each row. The adsorption fan 29 is a T-shaped... Model P04, the fixed plate 31 is a rectangular long plate with two sets. The activated carbon plate 36 is located between the two sets of fastening blocks 35, which are made of 316L stainless steel. When the resin material is sprayed, it emits a large amount of odor, which affects the working environment. Therefore, it is necessary to reduce the odor and minimize its impact on the working environment. The activated carbon plate 36 is pre-pressed by pushing the fastening block 35 spring 34, and the sleeve rod 33 moves in the sleeve 32, moving the activated carbon plate 36 between the two sets of fastening blocks 35. Then, the activated carbon plate 36 is attached to the outside of the multiple sets of exhaust channels 30. At this time, the fastening blocks 35 are released, allowing the two sets of fastening blocks 35 to reset and fix the position of the activated carbon plate 36. Then, the adsorption fan 29 adsorbs the air at the resin spraying point and filters the air through the filter screen 28. When the air is discharged through the exhaust channel 30, the odor is filtered by the activated carbon plate 36, thereby reducing the impact of the odor on the environment.

[0030] The working principle is as follows: First, a circular track is installed inside the chimney to provide a running track for the fiberglass spreading trolley 1, ensuring that the trolley 1 can move in a circle along the inner wall of the chimney. Its size and shape are customized according to the diameter and shape of the chimney. Then, the spreading trolley 1 moves on the circular track via wheels 2. The driver's cab 3 is used as a standing area for the workers. Next, the control panel 4 controls the spreading trolley 1 to operate. The pump 7 operates to deliver resin from the material box 6 to the spray gun 11. The spray gun 11 is angled by the angle motor 9, thus pre-applying resin to the chimney interior at the corresponding position of the spreading trolley 1, providing an adhesive base for the subsequent spreading of the fiberglass fabric. Then, the glass... The movable end of the fiber fabric is manually laid onto the inner wall of the resin-sprayed chimney pipe. Then, the compaction frame 13 moves up and down, driven by the compaction pole 12, and the fiberglass fabric is compacted by the compaction roller 15. This fiberglass fabric provides corrosion protection for the inside of the chimney. However, in the existing process, excess resin often falls off the inner wall of the chimney without adhering to the fabric. Therefore, this needs to be improved. First, the second assembly plate 18 and the first assembly plate 17 are attached. Then, the assembly screw 21 is fixed into the assembly screw groove 20, completing the installation of the recycling box 19. Finally, the attachment of the pole 16 is completed. The recycling bin 19 is moved so that it fits against the inner wall of the chimney to be sprayed. Excess resin material falling into the bin is collected. The triangular inclined plate 25 is installed in the recycling bin 19 via the first Velcro plate 23 and the second Velcro plate 24. The anti-stick layer 26 prevents resin from adhering to the recycling bin 19. When the recycling bin 19 is full, it is disassembled, and the resin material is poured out with the assistance of the triangular inclined plate 25 (tilted at a 45° angle), thus preventing excess resin material from falling. During resin spraying, the resin material emits a large amount of odor, which can affect the working environment. To reduce the emitted odor and minimize its impact on the working environment, the activated carbon plate 36 is pre-pressed by pushing the fastening block 35 and spring 34. The sleeve rod 33 moves within the sleeve 32, moving the activated carbon plate 36 between the two sets of fastening blocks 35. The activated carbon plate 36 then adheres to the outside of the multiple sets of exhaust channels 30. At this point, the fastening blocks 35 are released, allowing the two sets of fastening blocks 35 to reset and fix the position of the activated carbon plate 36. Subsequently, the adsorption fan 29 adsorbs the air at the resin spraying point and filters the air through the filter screen 28. When the air is discharged through the exhaust channel 30, the odor is filtered by the activated carbon plate 36, thereby reducing the impact of the odor on the environment.
