[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0034] Refer to Figure 1- Figure 3 An embodiment provided by the present utility model: A waste heat recovery device for chemical production and processing, including a reaction tank 1, which serves as the main container for chemical production and processing, conducts chemical reaction operations, generates heat, and is the source of waste heat recovery. A first tank body 2 is arranged outside the reaction tank 1. The top of the first tank body 2 is fixedly installed with a second tank body 21 through bolts, surrounding the outside of the reaction tank 1 to form an accommodating space. At the same time, water is added to the tank body to recover the waste heat generated by the reaction tank 1. The bolted fixed installation method facilitates disassembly and maintenance. An inlet water pipe is arranged on the left side of the top. When multiple reaction tanks 1 need to recover waste heat simultaneously, the inlet water pipe can be connected to the delivery pipe 4 on other devices for synchronous recovery. The top of the second tank body 21 is fixedly connected with a driving motor 3, which provides power for the stirring and scraping component, drives the driving gear 33 to rotate, and thus drives the rotating ring 31 to rotate. The lower right side of the first tank body 2 is fixedly connected with a delivery pipe 4, which conveys the water after waste heat recovery to a filter box 8 for filtering treatment. The right side of the delivery pipe 4 is fixedly connected with a filter box 8, and the right side of the filter box 8 is fixedly connected with a water pump 6, which provides power to convey the medium filtered by the filter box 8 to a high-pressure water tank 7.
[0035] Further, the right side of the water pump 6 is fixedly connected with a high-pressure water tank 7, which stores the water after filtration and waste heat recovery treatment. A heating pipe is arranged on the inner wall of the high-pressure water tank 7, which is used to reheat the already heated water. After the water vaporizes to form steam, it is reused, improving the utilization efficiency. A stirring and scraping component is arranged on the inner wall of the first tank body 2. The stirring and scraping component includes a rotating ring 31, which rotates under the drive of the driving motor 3, and thus drives the spoiler 34, the slide rod 35, and the scraper 37 to move. The rotating ring 31 is rotatably connected to the inner walls of the first tank body 2 and the second tank body 21. The bottom end of the rotating ring 31 is fixedly connected with a spoiler 34, which turbulates the medium in the first tank body 2 and the second tank body 21 as the rotating ring 31 rotates, improving the waste heat recovery efficiency. The inner wall of the spoiler 34 is slidably connected with a slide rod 35, which moves under the drive of the spoiler 34. At the same time, since the opposite sides of multiple slide rods 35 are elastically connected by a compression spring 36, the scraper 37 can adapt to different tank shapes and size changes.
[0036] Refer to Figure 2 、 Figure 3 and Figure 7, on the side of the slide bar 35 away from the spoiler 34, a scraping plate 37 is fixedly connected to scrape the inner wall of the tank, preventing impurities from adhering to the inner wall of the tank and affecting the waste heat recovery effect. The scraping plate 37 slides on the inner walls of the first tank 2 and the second tank 21. The side of the scraping plate 37 close to the inner walls of the first tank 2 and the second tank 21 is made of rubber material, which can not only increase the friction force to improve the scraping effect, but also avoid damaging the inner wall of the tank. Inside the swivel ring 31, a tooth 32 is fixedly connected, which meshes with the gear 33 to transmit the power of the drive motor 3 to the swivel ring 31. The outside of the tooth 32 meshes with the gear 33, and drives the swivel ring 31 to rotate by meshing with the tooth 32. The gear 33 is fixedly connected to the bottom end of the output shaft of the drive motor 3. A plurality of groups of slide bars 35 are provided, and the plurality of groups of slide bars 35 are symmetrically arranged with respect to the symmetry axis of the spoiler 34. The opposite sides of the two groups of slide bars 35 are elastically connected by a compression spring 36.
[0037] Refer to Figure 1 , Figure 4 and Figure 5 , a protective cover 81 is provided on the upper part of the filter box 8 to protect the filter screen 82 inside the filter box 8, prevent foreign impurities from entering the filter box 8, and at the same time cooperate with the filter box 8 to form a closed filtering space. The filter screen 82 is inserted into the inner wall of the filter box 8 to filter the medium passing through the filter box 8 and remove the impurities therein to ensure the cleanliness of the water. A disassembly component is provided on the inner wall of the filter box 8. The disassembly component includes a limit rod 51, and four groups are provided, respectively on the four sides of the filter box 8, which can improve the stability of the protective cover 81. At the same time, by being inserted into the jack 53 on the lower inner wall of the protective cover 81, the protective cover 81 is fixed. The limit rod 51 is set in an L shape.
[0038] Refer to Figure 4 - Figure 6 , the sides of the limit rod 51 close to the left and right sides of the filter box 8 are both inclined surfaces, which are convenient for operation and insertion into the jack 53. The limit rod 51 is slidably connected to the inner wall of the filter box 8. A groove 52 is opened at the bottom end of the limit rod 51, and under the elastic force of the sealing rubber pad 54, it is clamped with the inner wall of the jack 53 to enhance the fixing effect of the limit rod 51 on the protective cover 81. The jack 53 is penetrated through the lower inner wall of the protective cover 81 for the limit rod 51 to insert to fix the protective cover 81. The limit rod 51 is inserted into the inner wall of the jack 53.
[0039] Further, a sealing rubber pad 54 is provided on the inner wall of the top end of the filter box 8. The upper surface of the sealing rubber pad 54 fits against the lower surface of the protective cover 81, playing a sealing role to prevent the leakage of the medium during the filtering process. At the same time, it has a certain elasticity. When pressing the protective cover 81, the protective cover 81 can move up and down a certain distance. The inner side of the groove 52 is clamped on the inner wall of the jack 53. The high-pressure water tank 7 can be fixedly connected with a diversion pipe 41. The diversion pipe 41 is set to be arc-shaped. During the process that the water flow enters the high-pressure water tank 7 through the diversion pipe 41, a certain tangential force will be generated, causing the water in the high-pressure water tank 7 to rotate under the action of this tangential force, which can promote the flow and mixing of the water in the high-pressure water tank 7 and make the water temperature more uniform.
[0040] Working principle: When in use, the driving motor 3 is started, and the gear 33 at the bottom end of its output shaft rotates. By meshing with the teeth 32 inside the rotating ring 31, it drives the rotating ring 31 to rotate on the inner walls of the first tank body 2 and the second tank body 21. The spoiler 34 at the bottom end of the rotating ring 31 rotates accordingly, disturbing the water flow in the tank body and improving the waste heat recovery efficiency. Multiple sets of sliding rods 35 slidably connected to the inner wall of the spoiler 34 move under the drive of the spoiler 34.
[0041] The scraper 37 on the outer side of the sliding rod 35 scrapes the inner walls of the first tank body 2 and the second tank body 21 to prevent impurities from adhering to the inner wall of the tank body and affecting the waste heat recovery effect. The side of the scraper 37 close to the inner wall of the tank body is made of rubber material, which can not only increase the friction force to improve the scraping effect but also avoid damaging the inner wall of the tank body. Through the elastic force of the compression spring 36, the sliding rod 35 moves outward, enabling the scraper 37 to fit against the inner wall of the tank body, thus ensuring the cleaning effect.
[0042] When it is necessary to disassemble the protective cover 81 for the maintenance or replacement of the filter net 82, press the protective cover 81 to squeeze the sealing rubber pad 54, so that the jack 53 moves downward and slides out of the inner wall of the groove 52, releasing the limit on the limiting rod 51. At this time, just pull out the limiting rod 51 from the jack 53 to release the limit on the protective cover 81, and then the protective cover 81 can be removed to maintain or replace the filter net 82.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
