[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Please see Figures 1-4 The present invention provides the following technical solution:

[0036] A heat exchange device for yellow phosphorus production includes a heat exchange device shell 100, an inlet pipe 101 installed at the top left side of the heat exchange device shell 100, an outlet pipe 102 installed at the bottom right side of the heat exchange device shell 100, and heat exchange tubes 200 fixed inside the heat exchange device shell 100. It also includes:

[0037] The filter mechanism 300 is fixed on the heat exchange equipment housing 100. The filter mechanism 300 includes a filter box 301 that communicates with the heat exchange tube 200. A filter plate 302 is fixed in the middle of the filter box 301. An electric fan 303 is installed in the filter box 301 between the filter plate 302 and the heat exchange tube 200. The filter plate 302 intercepts media impurities to avoid clogging the heat exchange tube 200. The electric fan 303 accelerates air flow through forced convection to improve the heat exchange efficiency of the heat exchange tube 200. The filter box 301 is connected to the hot air generated in the production of yellow phosphorus.

[0038] The dust removal mechanism 400 includes a movable plate 401 that is slidably connected to the filter box 301. Several bristles 402 are regularly attached to one side of the movable plate 401 near the filter plate 302. The bristles 402 are in contact with the filter plate 302. The movable plate 401 with the bristles 402 slides to clean the filter plate 302 without manual disassembly, thus maintaining the filtration efficiency. To prevent heat leakage, baffles can be fixed on both the front and rear sides of the movable plate 401. The baffles need to completely cover the gaps in the slide groove 3010.

[0039] The collection mechanism 500 includes a collection box 502 that is slidably connected to the bottom of the filter box 301. The collection box 502 is located below the movable plate 401 and can collect brushed impurities in a timely manner for centralized processing.

[0040] In this embodiment, please refer to Figure 1 and Figure 2 The dust removal mechanism 400 also includes a motor 403 fixed to the top surface of the filter box 301. The output shaft of the motor 403 is fixed with a turntable 404, which provides a continuous power source for the reciprocating sliding of the movable plate 401, so that the brush 402 automatically and continuously cleans the filter plate 302, reducing manual maintenance costs.

[0041] Specifically, the top of the filter box 301 is provided with a groove 3010 that corresponds to the position and size of the movable plate 401. The top of the movable plate 401 passes through the groove 3010. A connecting rod 405 is hinged to the top surface of the turntable 404 near the edge. The other end of the connecting rod 405 is hinged to the movable plate 401, which converts the circular motion of the turntable 404 into the linear reciprocating motion of the movable plate 401, ensuring that the bristles 402 evenly cover the surface of the filter plate 302 and improve the cleaning effect.

[0042] In this embodiment, please refer to Figure 2 A number of heat exchange plates 103 are regularly fixed inside the housing 100 of the heat exchange equipment. The heat exchange plates 103 are closely attached to the heat exchange tube 200. By increasing the heat conduction area, the heat transfer process is enhanced, the heat exchange efficiency of the equipment is significantly improved, and energy consumption is reduced.

[0043] In this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The collection mechanism 500 also includes two receiving blocks 501 fixed to the bottom surface of the filter box 301. The two receiving blocks 501 are located on the left and right sides of the collection box 502 respectively. The top of the left and right sides of the collection box 502 are fixed with docking blocks 503. The docking blocks 503 cooperate with the receiving blocks 501 on the same side. The bottom of the filter box 301 is provided with a through groove 3011 that corresponds to the position of the collection box 502 and is adapted to the size. The receiving blocks 501 are L-shaped. The docking blocks 503 on both sides of the collection box 502 are inserted into the receiving blocks 501. The through groove 3011 is used to realize the sliding installation of the collection box 502, which not only ensures the stability of the installation, but also facilitates the pull-out and replacement.

[0044] Specifically, a U-shaped block 504 is fixed in the middle of the bottom surface of the receiving block 501. A movable column 505 is slidably connected to the horizontal plate of the U-shaped block 504. The top of the movable column 505 passes through the receiving block 501 on the same side and is inserted into the docking hole opened on the bottom surface of the docking block 503 on the same side, forming a mechanical locking structure, which effectively prevents the collection box 502 from shifting due to vibration during equipment operation and ensures the reliability of the collection mechanism.

[0045] Furthermore, a collar 506 is fixed to the outer wall of the mating block 503. A spring 507 is installed between the collar 506 and the U-shaped block 504 and sleeved on the outside of the movable column 505. When the movable column 505 is inserted into the mating hole, the spring 507 is compressed to generate elastic force, so that the movable column 505 automatically remains locked.

[0046] In addition, the bottom end of the movable column 505 extends to the U-shaped block 504. A pull ring 508 is fixed at the bottom end of the movable column 505. The pull ring 508 at the bottom end of the movable column 505 provides a force application point. By pulling the pull ring 508, the operator can overcome the elastic force of the spring 507 and easily pull out the movable column 505, thereby realizing the quick disassembly of the collection box 502 and improving the convenience of maintenance.

[0047] Finally, it should be noted that the electric fan 303 and motor 403 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0048] When the heat exchange equipment for yellow phosphorus production of this utility model is in use, the hot gas generated in the production of yellow phosphorus enters the heat exchange tube 200 through the filter box 301. The filter plate 302 in the filter box 301 intercepts dust, particles and other impurities in the medium, preventing impurities from entering the heat exchange tube 200 and causing blockage.

[0049] When the electric fan 303 starts, it accelerates airflow through forced convection, which helps filter impurities on the one hand and improves the heat exchange efficiency of the heat exchange tube 200 on the other hand. Together with the heat exchange fins 103 inside the shell, it increases the heat conduction area.

[0050] The filtered medium enters the heat exchange tube 200 and exchanges heat with the cooling water inside the heat exchange equipment shell 100. The cooled medium is discharged through the outlet pipe 102.

[0051] As the equipment operates, impurities gradually accumulate on the surface of the filter plate 302, affecting the filtration efficiency. At this time, the dust removal mechanism 400 is activated, the motor 403 is powered on, and the turntable 404 is driven to rotate. The connecting rod 405 on the edge of the turntable 404 is hinged to the movable plate 401, which converts the circular motion of the turntable 404 into the linear reciprocating sliding of the movable plate 401. The bristles 402 on the movable plate 401 contact the surface of the filter plate 302, and brush off the impurities on the filter plate 302 during the reciprocating sliding, thus achieving automated cleaning and avoiding manual disassembly and maintenance.

[0052] The brushed-off impurities fall from the filter plate 302 into the collection box 502 at the bottom of the filter box 301, achieving centralized collection of impurities;

[0053] The connecting blocks 503 on both sides of the collection box 502 are inserted into the receiving block 501 on the bottom of the filter box and locked by the movable column 505. The movable column 505 passes through the U-shaped block 504 and the receiving block 501 and is inserted into the connecting hole of the connecting block 503. The spring 507 provides elasticity to ensure that the collection box 502 is stable and does not slip. During maintenance, pull the pull ring 508 to overcome the elasticity of the spring 507 and pull out the movable column 505. The collection box 502 can then be pulled out from the receiving block 501, the impurities can be emptied, and it can be reinstalled.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
