[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 7 As shown, this utility model provides a waste incineration device with waste heat recovery, including an incineration device 1 and a waste heat recovery device 2. The incineration device 1 and the waste heat recovery device 2 are connected by a connecting pipe 3. A filter assembly 4 is installed in the middle of the connecting pipe 3. The filter assembly 4 includes a housing 401, a filter frame 402 installed inside the housing 401, a conical collection frame 403 fixedly connected to the bottom of the housing 401, a detachable plate 404 installed at the bottom of the conical collection frame 403, a cleaning assembly 5 installed at the top of the housing 401, a fixing assembly 6 installed on the front of the filter frame 402, a thrust assembly 7 installed on the back of the housing 401, a support plate 405 fixedly connected to the bottom of the inner side of the housing 401, and positioning strips 405 fixedly connected to the top of the support plate 405 and the top of the inner wall of the housing 401. 6. The cleaning component 5 includes a mounting bracket 501 fixedly connected to the top of the housing 401. A motor 502 is fixedly connected to the top right side of the mounting bracket 501. A swing plate 503 is fixedly connected to the output shaft of the motor 502. A first cylindrical block 504 is fixedly connected to one end of the swing plate 503. A connecting plate 505 is movably sleeved on the outer side of the first cylindrical block 504. A second cylindrical block 506 is fixedly connected to the end of the connecting plate 505 away from the first cylindrical block 504. The cleaning component 5 also includes a limiting post 510 fixedly connected to the middle of the top of the housing 401. A lifting rod 508 is movably sleeved on the inner side of the limiting post 510. A cleaning brush 509 is fixedly connected to the bottom of the lifting rod 508. A fixing ring 507 is fixedly connected to the top of the lifting rod 508. The fixing ring 507 is movably sleeved with the second cylindrical block 506.

[0026] In this embodiment, during use, flue gas carrying large solid particles enters the filter assembly 4 through the connecting pipe 3. The filter frame 402 can filter the large solid particles in the flue gas. After a long period of filtration, a lot of large dust particles will be attached to the surface of the filter frame 402, causing the filter frame 402 to become clogged. The motor 502 is started to drive the swing plate 503 to perform circular motion, thereby moving the lifting rod 508 vertically through the connecting plate 505. Then, the cleaning brush 509 can clean the large solid foreign objects attached to the left side of the filter frame 402. The cleaned dust is collected inside the cone-shaped collection frame 403, thereby avoiding the large solid dust particles from affecting the recovery of waste heat.

[0027] When the filter frame 402 needs to be disassembled and replaced, press the rectangular block 603 in the direction of mutual approach, so that the insert plate 604 separates from the inside of the fixing groove 412. Under the pushing force of the first spring 705, the push rod 702 pushes the filter frame 402 to move forward, and then the filter frame 402 can be directly taken out from the inside of the housing 401 to the front. When installing the filter frame 402, first slide the positioning slide groove 421 and the positioning strip 406 to position the filter frame 402. Then insert the filter frame 402 into the inside of the housing 401, and press the rectangular block 603 in the direction of mutual approach. When the back of the filter frame 402 contacts the back of the inner wall of the housing 401, the insert plate 604 is exactly aligned with the horizontal direction of the fixing groove 412. Under the pushing force of the cylindrical rod 602, the insert plate 604 is inserted into the inside of the fixing groove 412, thus completing the installation of the filter frame 402.

[0028] The bottom of the support plate 405 is fixedly connected to the closing plate 407, and the bottom of the closing plate 407 is fixedly connected to the inner side of the cone-shaped collection frame 403.

[0029] The sealing plate 407 can seal the space between the bottom of the support plate 405 and the inner side of the conical collection frame 403, preventing flue gas from entering the waste heat recovery device 2 through the bottom of the support plate 405.

[0030] The filter frame 402 has positioning grooves 421 at both the top and bottom, and the positioning grooves 421 are compatible with the positioning strips 406.

[0031] The positioning groove 421 and the positioning strip 406 work together to position the filter frame 402, preventing the filter frame 402 from shifting or tilting inside the housing 401.

[0032] The fixing component 6 includes a connecting frame 601 fixedly connected to the front of the filter frame 402. Cylindrical rods 602 are movably sleeved on both sides of the connecting frame 601. A rectangular block 603 is fixedly connected to one end of each cylindrical rod 602. An insert plate 604 is fixedly connected to the side of each rectangular block 603. A limit block 605 is fixedly connected to the other end of the cylindrical rod 602. A second spring 606 is provided on the outer side of the cylindrical rod 602, located between the rectangular block 603 and the side of the connecting frame 601. Two rectangular grooves 411 are formed on the front of the housing 401, and fixing grooves 412 are formed on the mutually distant surfaces of the inner walls of the two rectangular grooves 411.

[0033] The cylindrical rod 602 exerts a thrust on the two rectangular blocks 603 in a direction away from each other, thereby enabling the insert plate 604 to be stably inserted into the fixed groove 412 and preventing the filter frame 402 from falling off the front of the housing 401.

[0034] The thrust assembly 7 includes a fixed frame 701 fixedly connected to the back of the housing 401. A push rod 702 is movably sleeved on the back of the fixed frame 701. A fixed block 703 is fixedly connected to the back of the push rod 702. A stop block 704 is fixedly sleeved on the outside of the push rod 702. A first spring 705 is provided on the outside of the push rod 702. The first spring 705 is located between the stop block 704 and the inner wall of the fixed frame 701.

[0035] The push rod 702 is movably sleeved with the back of the housing 401. During the installation of the filter frame 402, the push rod 702 is pushed to move to the back, thereby compressing the first spring 705.

[0036] Working principle and usage process of this utility model:

[0037] During use, flue gas carrying large solid particles enters the filter assembly 4 through the connecting pipe 3. The filter frame 402 can filter the large solid particles in the flue gas. After a long period of filtration, a lot of large dust particles will be attached to the surface of the filter frame 402, causing the filter frame 402 to become clogged. The motor 502 is started to drive the swing plate 503 to perform a circular motion, thereby moving the lifting rod 508 vertically through the connecting plate 505. Then, the cleaning brush 509 can clean the large solid foreign objects attached to the left side of the filter frame 402. The cleaned dust is collected inside the cone-shaped collection frame 403, thus avoiding the large solid dust particles from affecting the recovery of waste heat.

[0038] When the filter frame 402 needs to be disassembled and replaced, press the rectangular block 603 in the direction of mutual approach, so that the insert plate 604 separates from the inside of the fixing groove 412. Under the pushing force of the first spring 705, the push rod 702 pushes the filter frame 402 to move forward, and then the filter frame 402 can be directly taken out from the inside of the housing 401 to the front. When installing the filter frame 402, first slide the positioning slide groove 421 and the positioning strip 406 to position the filter frame 402. Then insert the filter frame 402 into the inside of the housing 401, and press the rectangular block 603 in the direction of mutual approach. When the back of the filter frame 402 contacts the back of the inner wall of the housing 401, the insert plate 604 is exactly aligned with the horizontal direction of the fixing groove 412. Under the pushing force of the cylindrical rod 602, the insert plate 604 is inserted into the inside of the fixing groove 412, thus completing the installation of the filter frame 402.
