DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] like Figures 1 to 3 As shown, a wastewater treatment centrifuge according to one embodiment of the present invention includes a frame 1, on which is mounted a motor 11 and a housing assembly 12. A first belt 111 is installed between the motor 11 and the housing assembly 12. The housing assembly 12 is provided with a discharge pipe 121 and a drain pipe 122. Specifically, when the wastewater treatment centrifuge is in operation, the motor 11 drives the rotating drum of the housing assembly 12 via the first belt 111, thereby separating the wastewater and crystallized salts within the housing assembly 12. The separated crystallized salts are discharged through the discharge pipe 121, and the wastewater flows through the drain pipe 122 to the next process.

[0033] Since the crystallized salt is still adhered to wastewater, it will pollute the environment in the factory when it is piled up, and it will also increase the packaging and transportation costs. In order to further screen the wastewater from the crystallized salt discharged from the discharge pipe 121 and facilitate the pre-packaging of the crystallized salt, such as Figures 1 to 4 As shown, a hinge column 13 is fixedly connected to the support leg of the frame 1, and a material guide trough 4 is rotatably connected to the hinge column 13. The material guide trough 4 is provided with a through hole 403 matching the hinge column 13. The material guide trough 4 is also provided with a first opening 401 and a second opening 402, and a filter 5 is clamped in the first opening 401.

[0034] Specifically, the material guide trough 4 is located below the discharge pipe 121, and the crystallized salt discharged from the discharge pipe 121 will fall into the material guide trough 4. Because the material guide trough 4 is inclined, the crystallized salt will gradually slide toward the end of the material guide trough 4 where it is rotatably connected to the hinge column 13. As the crystallized salt slides within the material guide trough 4, it is further filtered by the filter screen 5, removing wastewater from the surface of the crystallized salt. Specifically, the wastewater on the surface of the crystallized salt leaks from the first opening 401 to the bottom of the material guide trough 4. After passing through the filter screen 5, the crystallized salt leaks from the second opening 402 to the bottom of the material guide trough 4.

[0035] It is worth noting that when there is too much wastewater on the surface of the crystallized salt, the crystallized salt will stick to the bottom wall of the guide trough 4, causing the crystallized salt to accumulate in the guide trough 4 and be unable to slide in the guide trough 4. In order to make the crystallized salt slide smoothly in the guide trough 4, a rotating component is installed on the frame 1, which can vibrate the guide trough 4.

[0036] Specifically, the rotating assembly includes a rotating base 2, to which a transmission rod 3 is rotatably connected. A second belt 112 is mounted on the motor 11. The end of the second belt 112 away from the motor 11 is sleeved on the transmission rod 3. A cam 31 is welded to the end of the transmission rod 3 away from the sleeved second belt 112. A pair of connecting brackets 41 are welded to the end of the guide chute 4 away from the hinge column 13. Connecting rods 411 are welded to the opposing side walls of the pair of connecting brackets 41. A rotating wheel 412 is rotatably connected to the connecting rods 411, and the cam 31 is connected to the rotating wheel 412.

[0037] Specifically, when the motor 11 is started, it also drives the transmission rod 3 to rotate, and the cam 31 will also rotate in the same manner as the transmission rod 3. When the cam 31 rotates, the wheel 412 also rotates on the surface of the cam 31, being continuously lifted and lowered by the cam 31. This drives the guide trough 4 to vibrate up and down at a high frequency. After being bumped, the crystallized salt on the guide trough 4 will continuously slide toward the end where the guide trough 4 connects to the hinge column 13. Furthermore, during the vibration of the crystallized salt, the wastewater adsorbed within the crystallized salt and the wastewater on the surface of the crystallized salt will be vibrated out, passing through the filter 5 and flowing out of the first opening 401. The crystallized salt is blocked by the filter 5 and continues to move toward the end where the guide trough 4 connects to the hinge column 13. After passing through the second opening 402, it leaks out of the second opening 402.

[0038] Furthermore, a limiting groove 311 matching the rotating wheel 412 is formed on the cam 31 , and the rotating wheel 412 is rotatably connected in the limiting groove 311 , thereby preventing the end of the guide chute 4 close to the cam 31 from swinging.

[0039] To prevent the rotating wheel 412 from disengaging from the limiting groove 311 when the cam 31 rotates at high speed, a fixing plate 14 is welded to the frame 1. A spring 141 is welded to the fixing plate 14. The end of the spring 141, which is away from the fixing plate 14, is welded to the material guide trough 4. Specifically, the elastic force of the spring 141 enables the rotating wheel 412 to rotate stably within the limiting groove 311, so that the surface of the rotating wheel 412 is always in contact with the surface of the limiting groove 311. This effectively ensures the vibration frequency of the material guide trough 4 and can better screen out the wastewater from the crystallized salt.

[0040] like Figure 4 、 Figure 5 and Figure 7 As shown, a protective frame 42 is welded to the lower panel of the guide chute 4, matching the first opening 401. A liquid leakage port 421 is formed in the protective frame 42, and a water collection tank 7 is located below the liquid leakage port 421. Wastewater filtered by the filter 5 leaks through the first opening 401, is guided by the protective frame 42, and ultimately flows into the water collection tank 7, where it is collected, preventing the wastewater from polluting the factory environment.

[0041] like Figures 4 to 7As shown, a bulk material tower 6 is welded to the material guide trough 4, matching the second opening 402. Specifically, a pair of connecting plates 61 are fixedly connected to the opposite side walls of the bulk material tower 6, and the bulk material tower 6 is fixedly connected to the side walls of the material guide trough 4 via the connecting plates 61. The bulk material tower 6 is conical and has a distribution hole 601 formed therein. After the crystallized salt leaking from the second opening 402 is diverted through the distribution hole 601, it can be evenly deposited into the collection box 8, making the surface of the crystallized salt in the collection box 8 level, without being high in the middle and low on both sides, which facilitates the sealing and packaging of the collection box 8.

[0042] During use, the motor 11 drives the transmission rod 3 to rotate. The rotation of the cam 31 on the transmission rod 3 cooperates with the rotating wheel 412 to cause the guide trough 4 to vibrate at high speed. The crystallized salt discharged from the discharge pipe 121 falls on the high-speed vibrating guide trough 4 and gradually moves toward the end of the guide trough 4 connected to the hinge column 13. After the crystallized salt is subjected to high-speed vibration in the guide trough 4, the moisture in the crystallized salt is vibrated out and leaks from the first opening 401 into the water collection tank 7. After being blocked by the filter screen 5, the crystallized salt continues to move. When passing through the second opening 402, it leaks from the second opening 402 and eventually falls into the collection tank 8. After the collection tank 8 is sealed, the crystallized salt can be collected.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
