Description

Technical Field

[0001] This utility model relates to the field of pyrazol production technology, specifically to a heat recovery device for pyrazol production lines. Background Technology

[0002] Waste heat refers to the sensible and latent heat that has not been rationally utilized in the original design of energy-consuming equipment in industrial enterprises due to limitations imposed by historical, technological, and conceptual factors. It includes waste heat from high-temperature exhaust gases, cooling media, waste steam and wastewater, high-temperature products and slag, chemical reactions, combustible waste gases and liquids, and waste materials. In the production of pyrazol, the solvent used to produce pyrazol generates a large amount of heat energy due to chemical reactions. If this heat energy is not recovered and utilized, it will result in energy waste. Existing heat recovery devices mostly use heat exchangers as intermediaries for heat recovery, resulting in some heat loss and preventing direct use of the heat energy. Therefore, we propose a heat recovery device for pyrazol production lines. In the prior art, such as the announcement number CN212409109U, a heat recovery device for a pyrazol production line is proposed. This technical solution discloses a heat recovery device for a pyrazol production line, relating to the technical field of heat recovery devices. A heat recovery device for a pyrazol production line includes an electric telescopic cylinder, an electric telescopic rod movably mounted on the top of the electric telescopic cylinder, a connecting body fixedly mounted on the top of the electric telescopic rod, a tensioning body fixedly mounted on the bottom of the connecting body, a steel conduit fixedly mounted inside the tensioning body, a reaction tank and a heat tank movably arranged at the bottom of the connecting body, a first inlet pipe and a first outlet pipe fixedly mounted on the outer wall of the reaction tank, and a first driving body fixedly mounted at the bottom of the steel conduit. This utility model, by setting an electric telescopic cylinder, realizes the tilting loading of raw materials, improving production efficiency, while facilitating the cleaning and maintenance of the reaction tank and heat tank, making it convenient to use. The trapezoidal cross-section of the cover enables rapid collection of airflow, facilitating the rapid transport of hot air. However, when using the heat recovery device in the existing pyrazol production line, the raw materials are added into the reaction tank and the heat tank, and then the raw materials that promote the reaction of pyrazol are added into the reaction tank, which can generate heat inside the reaction tank. Since there is no stirring mechanism inside the reaction tank, it is difficult for the raw materials inside the reaction tank to react fully. To address the aforementioned issues, this application proposes a heat recovery device for pyrazol production lines. Utility Model Content

[0003] This utility model aims to provide a heat recovery device for pyrazol production lines, mainly to solve the problem that existing heat recovery devices for pyrazol production lines lack a stirring mechanism, making it difficult for raw materials inside the reaction tank to react fully.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: The heat recovery device for a pyrazol production line includes an electric telescopic cylinder, a connecting body, a steel conduit, a reaction vessel, and a heat energy tank. Both the reaction vessel and the heat energy tank have covers on their tops. A drive housing is fixedly connected to the top of each cover, and the top of each drive housing is fixedly connected to the steel conduit. The steel conduit communicates with the interior of the drive housing. A motor is fixedly installed on the top of the inner wall of the drive housing. A rotating shaft is fixedly connected to the output end of the motor, and a fan is fixedly connected to the other end of the rotating shaft. A rotating rod is fixedly connected to the bottom of the fan inside the drive housing above the reaction vessel. The lower end of the rotating rod extends into the interior of the reaction vessel. A stirring blade is detachably connected to the outer wall of the rotating rod. A block is fixedly connected to one end of the stirring blade. A slot matching the block is provided on the outer wall of the rotating rod. A limiting component is provided on the block to fix it inside the slot. A cleaning component is provided at the lower end of the rotating rod to clean the bottom of the inner wall of the reaction vessel.

[0005] The working principle and beneficial effects of this utility model: Working principle: When using this device, (activating the electric telescopic cylinder pulls the first cover out of the reaction tank via the steel conduit, and then pulls the second cover out of the heat tank via the steel conduit; the raw materials to be reacted are added to the reaction tank and the inner heat tank respectively through the first and second feed pipes; activating the electric telescopic cylinder places the first cover on top of the reaction tank and the second cover on top of the heat tank; the raw materials that promote the pyrazol reaction are added through the first feed pipe; the first and second feed pipes are closed in time; the first and second motors are turned on, so that the heat generated during the pyrazol reaction is transmitted through the first and second fan blades...) The fan moves the reaction vessel to the outside of the inner heating vessel, thus heating the inner heating vessel. (The part in parentheses refers to prior art, which is not described in detail in this application.) During the reaction of the pyrazol raw material on the inner wall of the reaction vessel, the motor drives the fan to rotate. The fan rotates, causing the rotating rod at its bottom to rotate. The stirring blades on the outer wall of the rotating rod can stir the pyrazol raw material inside the reaction vessel. At the same time, the cleaning component at the lower end of the rotating rod can clean the pyrazol precipitate at the bottom of the reaction vessel, thereby effectively ensuring the full reaction of the pyrazol raw material inside the reaction vessel.

[0006] Beneficial effects: During operation, the stirring blades on the outer wall of the rotating rod can stir the pyrazol raw material inside the reaction tank. This not only improves the reaction efficiency of the raw material inside the reaction tank, but also allows the raw material inside the reaction tank to react fully. The cleaning component at the lower end of the rotating rod can effectively prevent the pyrazol raw material from settling at the bottom of the reaction tank, thus allowing the raw material inside the reaction tank to react more fully.

[0007] Preferably, the limiting component includes a sliding cavity inside the insert block, with the sliding cavities symmetrically arranged inside the insert block. A movable plate is slidably connected inside each sliding cavity. A spring is fixedly connected to one side of each movable plate, and the other end of the spring is fixedly connected to the inner wall of the sliding cavity. A button and a wedge block are fixedly connected to the side of the movable plate away from the spring. Both the button and the wedge block extend out of the insert block and are slidably connected to it. Limiting grooves matching the wedge blocks are provided at the top and bottom of the slot's inner wall. The insert block at one end of the stirring blade is inserted into the limiting groove on the outer wall of the rotating rod. When the insert is inserted into the slot, the wedge-shaped block on the insert will automatically move into the sliding cavity under pressure. When the insert is fully inserted into the slot, the moving plate will move the wedge-shaped block outward under the movement of the spring, and make the wedge-shaped block lock into the limiting groove, thus fixing the insert into the slot. The device can then operate normally. Pressing the buttons on the top and bottom of the insert will move the wedge-shaped block into the sliding cavity through the moving plate. When the wedge-shaped block is disengaged from the limiting groove, the stirring blade can be disassembled, which makes it convenient for the staff to clean or replace the stirring blade.

[0008] Preferably, the cleaning assembly includes a crossbar connected to the lower end of the rotating rod, a threaded post fixedly connected to the top of the crossbar, a threaded groove matching the threaded post at the lower end of the rotating rod, and a brush fixedly connected to the bottom of the crossbar. When the rotating rod rotates, the crossbar can rotate at the bottom of the reaction vessel. The brush at the bottom of the crossbar can clean the pyrazol precipitate at the bottom of the reaction vessel, which can effectively prevent the pyrazol from precipitating away from the bottom of the reaction vessel. The crossbar is fixed to the lower end of the rotating rod by a threaded connection, which can facilitate the disassembly of the crossbar by the operator, thereby facilitating the cleaning or replacement of the brush.

[0009] Preferably, there are multiple stirring blades, and the stirring blades are evenly distributed in an array on the rotating rod. By setting the number of stirring blades on the rotating rod to multiple, multiple stirring blades can achieve a better stirring effect on the raw materials inside the reaction vessel, thereby further improving the reaction efficiency of the raw materials inside the reaction vessel.

[0010] Preferably, a washer is fixedly connected to the lower end of the rotating rod, and the washer is made of rubber material. After the crossbar is installed at the lower end of the rotating rod, the washer at the lower end of the rotating rod will press against the crossbar. This can effectively prevent the crossbar from loosening during the operation of the device, thereby making the connection between the crossbar and the rotating rod more secure.

[0011] Preferably, the stirring blades on the outer wall of the rotating rod are inclined. By setting the stirring blades to an inclined state, the resistance between the stirring blades and the raw materials inside the reaction vessel can be effectively reduced when the rotating rod drives the stirring blades to rotate. This not only effectively extends the service life of the stirring blades, but also provides a better stirring effect on the raw materials inside the reaction vessel.

[0012] Preferably, all corners at the slot opening are chamfered. By chamfering all corners at the slot opening, it is easier to insert the insert into the slot, thus making the installation of the stirring blade easier. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1-4A heat recovery device for a pyrazol production line includes an electric telescopic cylinder 1, a connecting body 2, a steel conduit 3, a reaction tank 4, and a heat energy tank 5. Both the reaction tank 4 and the heat energy tank 5 have covers 6 connected to their tops. A drive housing 7 is fixedly connected to the top of each cover 6. The top of each drive housing 7 is fixedly connected to the steel conduit 3, and the steel conduit 3 communicates with the interior of the drive housing 7. A motor 8 is fixedly installed on the top of the inner wall of the drive housing 7. A rotating shaft 9 is fixedly connected to the output end of the motor 8, and a fan 10 is fixedly connected to the other end of the rotating shaft 9. (Activating the electric telescopic cylinder causes the steel conduit to pull the first cover out of the reaction tank, and then pulls the second cover out of the heat energy tank. The heat energy is then fed into the reaction tank through the first and second inlet pipes, respectively.) The raw materials to be reacted are added to the reaction tank and the internal heating tank. The electric telescopic cylinder is activated to place the first cover into the top of the reaction tank and the second cover into the top of the heat energy tank. The raw materials that promote the reaction of pyrazol are added through the first feed pipe. The first and second feed pipes are closed in time, and the first and second motors are turned on so that the heat generated during the reaction of pyrazol is moved from the reaction tank to the outside of the internal heating tank by the fan action of the first and second fan blades, thus realizing the heating of the internal heating tank. (The part in parentheses is prior art, which is not described in detail in this application.) The bottom of the fan 10 inside the drive shell 7 above the reaction tank 4 is fixedly connected to a rotating rod 11. The lower end of the rotating rod 11 extends into the interior of the reaction tank 4, and the outer wall of the rotating rod 11 is detachable. Multiple stirring blades 12 are connected in an array and are evenly distributed on the rotating rod 11. The motor 8 drives the fan 10 to rotate, which in turn rotates the rotating rod 11 at its bottom. The stirring blades 12, which are mounted on the outer wall of the rotating rod 11, can stir the pyrazol raw material inside the reaction vessel 4. The stirring blades 12 are all inclined, which effectively reduces the resistance between the stirring blades 12 and the raw material inside the reaction vessel 4 when the rotating rod 11 drives the stirring blades 12 to rotate. This not only effectively extends the service life of the stirring blades 12, but also provides a better stirring effect on the raw material inside the reaction vessel 4. One end of the stirring blade 12 is fixedly connected to an insert 13, and the outer wall of the rotating rod 11 has an opening for connecting the insert 13. The slot 14 that matches the 13 is chamfered at the corners of the slot 14 opening, which makes it easier to insert the 13 into the slot 14. The 13 is provided with a limiting component for fixing the 13 into the slot 14. The 13 is fixed into the slot 14 by the limiting component, which makes it easy for the staff to disassemble and assemble the stirring blade 12, so as to facilitate the cleaning or replacement of the stirring blade 12. The lower end of the rotating rod 11 is provided with a cleaning component for cleaning the bottom of the inner wall of the reaction vessel 4. At the same time, the cleaning component at the lower end of the rotating rod 11 can clean the pyrazol precipitate at the bottom of the reaction vessel 4, thereby effectively ensuring the full reaction of the pyrazol raw material inside the reaction vessel 4.

[0017] like Figure 2 and Figure 4As shown, the limiting assembly includes a sliding cavity 15 inside the insert block 13, and the sliding cavities 15 are symmetrically arranged inside the insert block 13. A movable plate 16 is slidably connected inside each sliding cavity 15. A spring 17 is fixedly connected to one side of the movable plate 16, and the other end of the spring 17 is fixedly connected to the inner wall of the sliding cavity 15. A button 18 and a wedge block 19 are fixedly connected to the side of the movable plate 16 away from the spring 17. Both the button 18 and the wedge block 19 extend out of the insert block 13, and both are slidably connected to the insert block 13. Limiting grooves 20 matching the wedge block 19 are provided at the top and bottom of the inner wall of the slot 14. The insert block 13 at one end of the stirring blade 12 is inserted into the outside of the rotating rod 11. When the insert 13 is inserted into the slot 14, the wedge 19 on the insert 13 will be squeezed and automatically move into the slide cavity 15. After the insert 13 is fully inserted into the slot 14, the moving plate 16 will move the wedge 19 outward under the movement of the spring 17 and make the wedge 19 lock into the limiting groove 20, thus fixing the insert 13 inside the slot 14. The device can then operate normally. At the same time, pressing the buttons 18 on the top and bottom of the insert 13 will move the wedge 19 into the slide cavity 15 through the moving plate 16. After the wedge 19 is disengaged from the limiting groove 20, the stirring blade 12 can be disassembled, which makes it convenient for the staff to clean or replace the stirring blade 12.

[0018] like Figure 2 and Figure 3 As shown, the cleaning assembly includes a crossbar 21 connected to the lower end of a rotating rod 11. A threaded post 22 is fixedly connected to the top of the crossbar 21. A threaded groove 23 matching the threaded post 22 is opened at the lower end of the rotating rod 11. A gasket 25 made of rubber is fixedly connected to the lower end of the rotating rod 11. A brush 24 is fixedly connected to the bottom of the crossbar 21. When the rotating rod 11 rotates, the crossbar 21 can rotate at the bottom of the reaction vessel 4. The brush 24 at the bottom of the crossbar 21 can clean the pyrazol precipitate at the bottom of the reaction vessel 4. This can effectively prevent the pyrazol from precipitating at the bottom of the reaction vessel 4. The crossbar 21 is fixed to the lower end of the rotating rod 11 by a threaded connection, which makes it easy for the staff to disassemble the crossbar 21, thereby making it easy for the staff to clean or replace the brush 24.

[0019] As can be seen from the above, the specific embodiments of this utility model are as follows: When using this device, (activating the electric telescopic cylinder pulls the first cover out of the reaction tank via the steel conduit, and then pulls the second cover out of the heat tank via the steel conduit; the raw materials to be reacted are added to the reaction tank and the inner heating tank respectively through the first and second feed pipes; activating the electric telescopic cylinder places the first cover on top of the reaction tank and the second cover on top of the heat tank; the raw materials that promote the pyrazol reaction are added through the first feed pipe; the first and second feed pipes are closed in time; the first and second motors are turned on, so that the heat generated during the pyrazol reaction is moved from the reaction tank to the outside of the inner heating tank by the fan action of the first and second fan blades, thus realizing the internal heating...) (The heating operation of the tank is described in parentheses; the prior art is not elaborated upon in this application.) During the reaction of the pyrazol raw material inside the reaction tank 4, the motor 8 drives the fan 10 to rotate. Simultaneously, the fan 10 rotates, causing the bottom rotating rod 11 to rotate. The stirring blades 12 on the outer wall of the rotating rod 11 stir the pyrazol raw material inside the reaction tank 4. The rotation of the rotating rod 11 also causes the crossbar 21 to rotate at the bottom of the reaction tank 4. The brush 24 at the bottom of the crossbar 21 cleans the pyrazol precipitate at the bottom of the reaction tank 4, effectively preventing the pyrazol from precipitating at the bottom of the reaction tank 4. This device not only improves the reaction efficiency of the raw materials inside the reaction vessel 4, but also allows the raw materials inside the reaction vessel 4 to react more fully. After the device is used, the electric telescopic cylinder 1 is activated to pull the cover 6 out of the reaction vessel 4 and the heat tank 5 respectively through the steel guide tube 3. At the same time, the buttons 18 on the top and bottom of the insert block 13 are pressed, and the wedge block 19 can be moved into the sliding cavity 15 by the moving plate 16. When the wedge block 19 is disengaged from the limiting groove 20, the stirring blade 12 can be disassembled, which makes it convenient for the staff to clean or replace the stirring blade 12. Insert the insert block 13 at one end of the stirring blade 12 into the slot 14 on the outer wall of the rotating rod 11. When the wedge-shaped block 19 on the insert 13 is squeezed, it will automatically move into the sliding cavity 15. When the insert 13 is fully inserted into the slot 14, the moving plate 16 will drive the wedge-shaped block 19 to move outward under the movement of the spring 17, and make the wedge-shaped block 19 lock into the limiting groove 20, thus fixing the insert 13 into the slot 14, thereby completing the installation of the stirring blade 12. By rotating the crossbar 21, it can be removed from the lower end of the rotating rod 11, which makes it convenient for the staff to clean or replace the brush 24. After the brush 24 is cleaned or replaced, the crossbar 21 is installed back to the lower end of the rotating rod 11, and the device can operate normally.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
