Description

Technical Field

[0001] This utility model relates to the field of phosphorous acid turnover tank technology, specifically a phosphorous acid turnover tank constant temperature device. Background Technology

[0002] In the chemical production field, maintaining a stable temperature is crucial for the chemical properties and performance of phosphorous acid during storage and handling. Therefore, constant temperature baths are often used to treat phosphorous acid at a constant temperature. Existing constant temperature devices for phosphorous acid handling tanks mainly use heating rods to heat the phosphorous acid in the tank to maintain the required temperature. However, in actual use, phosphorous acid easily adheres to the surface of the heating rods and gradually forms impurities.

[0003] Because existing constant-temperature baths lack an effective cleaning mechanism, the surface of the heating rods cannot be cleaned. Over time, these adhering phosphorous acid impurities accumulate, hindering effective heat transfer, reducing the heating efficiency of the heating rods, and causing phosphorous acid to fail to maintain a stable constant temperature. This affects the stability of the production process and product quality, and may also lead to safety hazards due to localized overheating. Furthermore, to ensure heating effectiveness, operators need to frequently disassemble the heating rods for manual cleaning, which increases labor intensity and costs, and can easily damage the heating rods during disassembly, further shortening equipment lifespan and increasing maintenance costs. Therefore, there is an urgent need to design a constant-temperature device for phosphorous acid turnover tanks that can automatically clean impurities from the heating rod surface to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a constant temperature device for a phosphorous acid turnover tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature device for a phosphorous acid turnover tank, comprising a constant temperature tank, a support plate fixed to the inner wall of the constant temperature tank, a plurality of heating rods fixed at equal intervals at the bottom end of the support plate, a limit rod fixed to the bottom end of the heating rod, a cleaning component sleeved on the outer wall of the limit rod, and a connecting rod fixed between each cleaning component, a threaded block fixed to the inner side of the support rod at the edge, a screw threadedly connected to the inside of the threaded block, a rotating block fixed to the bottom end of the screw, and a driving component provided at the top end of the screw.

[0006] Preferably, the bottom center of the constant temperature bath is provided with a groove that matches the rotating block.

[0007] Preferably, the cleaning component includes a sleeve, which is fitted onto the outer wall of the limiting rod, a cleaning strip is fixed to the inner wall of the sleeve, and the outer wall of the sleeve is connected to the connecting rod.

[0008] Preferably, the cleaning strip is made of a corrosion-resistant and high-temperature-resistant material.

[0009] Preferably, the driving component includes a horizontal plate, which is fixed at the top center of the constant temperature bath. A motor is fixed at the top of the horizontal plate. A limit block is sleeved on the outer wall of the screw, and the limit block is connected to the inner wall of the constant temperature bath.

[0010] Preferably, the horizontal plate has a through hole inside, and the output end of the motor is connected to the screw through hole.

[0011] Preferably, the support plate is semi-circular in shape, and heating rods are fixed at equal intervals at the bottom of the semi-circular support plate. The heating rods can be controlled by a thermostat.

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

[0013] The cleaning component is designed to automatically remove phosphorous acid impurities adhering to the surface of the heating rod. When cleaning is required, the motor drives the screw to rotate, and the threaded block moves on the screw, thereby moving the cleaning component upward along the limit rod. The cleaning strip makes close contact with the heating rod, scraping off the impurities on the surface of the heating rod during the movement. This automatic cleaning mechanism eliminates the need for manual disassembly of the heating rod, greatly improving cleaning efficiency, reducing manual maintenance costs and labor intensity, and avoiding potential damage to the heating rod during manual cleaning.

[0014] The rotating block and limiting block provide limiting support for the screw's rotation, ensuring that the screw will not deviate or wobble during rotation, making the movement of the cleaning parts more stable and accurate. At the same time, the threaded connection between the threaded block and the screw ensures that the cleaning parts can move up and down according to a predetermined trajectory, further improving the reliability and stability of the device operation;

[0015] The cleaning strip is made of corrosion-resistant and high-temperature resistant material, which can work stably for a long time in the high-temperature and corrosive environment of phosphorous acid. This effectively extends the service life of the cleaning strip, reduces the need for frequent replacement due to cleaning strip damage, lowers equipment maintenance costs, and improves the overall durability of the device.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a constant temperature device for a phosphorous acid turnover tank: A constant temperature device for a phosphorous acid turnover tank includes a constant temperature tank 1. A support plate 2 is fixed to the inner wall of the constant temperature tank 1. The support plate 2 is used to support heating rods 3. Multiple heating rods 3 are fixed at equal intervals at the bottom end of the support plate 2. The heating rods 3 are used to heat the phosphorous acid inside the constant temperature tank 1 to maintain a constant temperature. A limiting rod 4 is fixed to the bottom end of the heating rod 3. The limiting rod 4 is used to limit and support a cleaning component. A cleaning component is sleeved on the outer wall of the limiting rod 4. The cleaning component can be heated... The surface of rod 3 is cleaned of the adhering phosphorous acid, and each cleaning component is fixed with a connecting rod 7. The inner side of the edge support rod 7 is fixed with a threaded block 8. The threaded block 8 can move upward on its outer wall by rotating the screw 10. The screw 10 is connected to the screw 10 internally by threads. The bottom end of the screw 10 is fixed with a rotating block 9. The rotating block 9 can support the screw 10 when it rotates. The top end of the screw 10 is provided with a driving component. The driving component can drive the screw 10 to rotate. The bottom center of the constant temperature bath 1 is provided with a groove that matches the rotating block 9.

[0023] The cleaning component includes a sleeve 5, which is fitted onto the outer wall of the limiting rod 4. The sleeve 5 can support the cleaning strip 6. The cleaning strip 6 is fixed to the inner wall of the sleeve 5. The cleaning strip 6 cleans the heating rod 3. The outer wall of the sleeve 5 is connected to the connecting rod 7. The cleaning strip is made of a corrosion-resistant and high-temperature resistant material.

[0024] The driving component includes a horizontal plate 12, which is fixed at the top center of the constant temperature bath 1. The horizontal plate 12 can provide support for the motor 13. The motor 13 is fixed at the top of the horizontal plate 12. A limit block 11 is sleeved on the outer wall of the screw 10. The limit block 11 can limit the rotation of the screw 10. The limit block 11 is connected to the inner wall of the constant temperature bath 1. A through hole is opened inside the horizontal plate 12.

[0025] Working Principle: When a constant temperature device for a phosphorous acid turnover tank is first used, the phosphorous acid inside the constant temperature tank 1 can be kept at a constant temperature by the heating rod 3. When the constant temperature tank 1 needs to be cleaned after long-term use, the motor 13 is started by controlling the external control unit. The output end of the motor 13 drives the screw 10 to rotate. When the screw 10 rotates, the rotating block 9 and the limiting block 11 can limit the rotating screw 10. During the rotation of the screw 10, the threaded block 8 moves upward on the outer wall of the screw 10. When moving, the cleaning strip 6 moves upward on the outer wall of the limiting rod 4 and fits on the outer wall of the heating rod 3. The continuous upward movement of the cleaning strip 6 can clean the phosphorous acid impurities attached to the surface of the heating rod 3. After cleaning, the motor 13 rotates in the opposite direction, which drives the threaded block 8 to move downward to reset the screw 10. When the cleaning strip 6 moves downward to the outer wall of the limiting rod 4, the user can control the motor 13 to stop working through the external control unit.
