Description

Technical Field

[0001] This utility model relates to the field of gallium recycling production technology, and in particular to a filter press for gallium recycling processes. Background Technology

[0002] The gallium recovery process typically involves steps such as chemical precipitation and adsorption. These processes generate gallium-containing solid particles (such as gallium hydroxide), which need to be separated from the liquid using a filter press to ensure a purer subsequent processing.

[0003] Currently, after the filter cake is finished, traditional filter presses require manual pushing of the receiving trough to collect it. However, because the sludge is compressed into a plate shape under the action of the filter press, it is not easy for the sludge to disperse when it falls into the receiving trough, which can easily cause accumulation and blockage, affecting the collection efficiency. In addition, traditional filter presses usually only have one discharge port and one receiving trough, so the production efficiency is limited and the practicality is low. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filter press for gallium recovery processes. This addresses the problems of traditional filter presses, where manual operation of the receiving trough is required to collect the filter cake after filtration. Furthermore, the sludge is compressed into plate-like shapes by the filter press, making it difficult for the sludge to disperse in the receiving trough, leading to accumulation and blockage, thus affecting collection efficiency. Additionally, traditional filter presses typically have only one outlet and one receiving trough, resulting in limited production efficiency and low practicality.

[0005] This utility model provides a filter press for gallium recovery processes, including a frame and a filter press mechanism disposed on the frame, and further comprising:

[0006] The housing is mounted on the frame and located below the filter press mechanism. The housing has a conveying chamber and a first discharge port, a second discharge port, and an inlet located between the first discharge port and the second discharge port, which are connected to the conveying chamber.

[0007] Two collection boxes are respectively located below the first discharge port and the second discharge port;

[0008] The conveying mechanism includes a conveying motor located on one side of the housing and a spiral auger rotatably located in the conveying chamber. The output end of the conveying motor is connected to one end of the spiral auger to drive it to rotate.

[0009] Furthermore, a feed hopper is provided on the frame above the housing, and the lower end of the feed hopper is connected to the feed inlet.

[0010] Furthermore, both the first and second discharge ports are equipped with discharge hoppers at their outlet ends.

[0011] Furthermore, the upper inner wall of the discharge hopper is provided with slide rails on both sides, the slide rails are inserted with slide grooves, the slide grooves are fixedly connected with filter plates, and the filter plates are provided with handles.

[0012] Furthermore, the collection box is equipped with casters at the bottom and a handle on one side.

[0013] Furthermore, a drain pipe is connected to the bottom of the collection box, and the inside of the collection box is connected to the outside through the drain pipe, which is equipped with a valve.

[0014] Furthermore, the collection box is provided with filter holes, and the collection box is connected to the drain pipe through the filter holes.

[0015] Furthermore, the filter press mechanism includes a thrust plate on one side of the frame, a pushing component on the other side of the frame, a pushing plate connected to the output end of the pushing component, and a plurality of filter press plates disposed between the thrust plate and the pushing plate and sliding on the frame, wherein each filter press plate is provided with a water outlet pipe on one side.

[0016] Furthermore, the frame is also provided with a water collection tank, which is located below the water outlet pipe, and a drain pipe is provided on one side of the water collection tank.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model discloses a filter press for gallium recovery processes. By controlling the conveying motor to drive the spiral auger to rotate in both directions, the filter cake can be continuously transported between two discharge ports, improving production efficiency and reliability. The spiral auger can also break up the filter cake during the conveying process, ensuring that the filter cake is evenly distributed in the conveying chamber, thereby reducing the risk of local accumulation or blockage. At the same time, it can also appropriately compact the filter cake, reducing its volume and thus improving the utilization rate of the collection box.

[0019] This utility model discloses a filter press for gallium recovery processes. During operation, a gallium-containing suspension enters the filter press mechanism via a pump or other conveying device, forming a filter cake. Once formed, the filter cake falls into the feed inlet of the housing. Subsequently, a spiral auger, driven by a conveying motor, rotates, pushing the filter cake from the feed inlet into the conveying chamber, and finally discharges it from either the first or second discharge outlet into a corresponding collection box. When the filter cake enters the housing through the feed inlet, the rotation direction of the spiral auger can be changed by controlling the forward and reverse rotation of the conveying motor. This allows the filter cake to be first conveyed to the first discharge outlet and then fall into the corresponding collection box. When the collection box is nearly full, the conveying motor is then controlled to convey the filter cake to the second discharge outlet, where it falls into the corresponding collection box, thus ensuring the continuity and efficiency of the production process.

[0035] like Figure 1-5 As shown, an embodiment of this utility model provides a filter press for a gallium recovery process, including a frame 10 and a filter press mechanism 20 disposed on the frame 10, and further including: a housing 30 disposed on the frame 10 and below the filter press mechanism 20, the housing 30 having a conveying chamber 31 and a first discharge port 32 and a second discharge port 33 communicating with the conveying chamber 31, and a feed port 34 located between the first discharge port 32 and the second discharge port 33; and two collection boxes 40 respectively disposed at the first discharge port 32 and the second discharge port 33. Below 3; conveying mechanism 50, including a conveying motor 51 located on one side of the housing 30 and a spiral auger 52 rotatably located in the conveying chamber 31. The output end of the conveying motor 51 is connected to one end of the spiral auger 52 to drive its rotation. The spiral auger 52 can break up larger filter cakes during the conveying process, so that the filter cake can be evenly distributed in the conveying chamber 31, reducing the risk of local accumulation or blockage. At the same time, it can also appropriately compact the filter cake, reduce its volume, and thus improve the utilization rate of the collection box 40.

[0036] In this embodiment of the invention, the gallium-containing suspension enters the filter press mechanism 20 through a pump or other conveying device and forms a filter cake under the action of the filter press mechanism 20. After the filter cake is formed, it falls into the feed inlet 34 inside the housing 30. Then, the auger 52 rotates under the drive of the conveying motor 51, pushing the filter cake from the feed inlet 34 into the conveying chamber 31, and finally discharges from the first discharge outlet 32 ​​or the second discharge outlet 33 into the corresponding collection box 40. When the filter cake enters the housing 30 through the feed inlet 34, the rotation direction of the auger 52 can be changed by controlling the forward and reverse rotation of the conveying motor 51. In this way, the filter cake can be first conveyed to the first discharge outlet 32 ​​and then fall into the corresponding collection box 40. When the collection box 40 is almost full, the filter cake is then conveyed to the second discharge outlet 33 by controlling the conveying motor 51 and then falls into the corresponding collection box 40, thereby ensuring the continuity and efficiency of the production process.

[0037] Based on the above solutions, such as Figure 1-3 As shown in this embodiment of the present invention, a feed hopper 60 is provided on the frame 10 above the housing 30, and the lower end of the feed hopper 60 is connected to the feed inlet 34; specifically, the feed hopper 60 is funnel-shaped or cone-shaped to ensure that the filter cake can slide smoothly to the feed inlet 34 at the lower end, reducing the risk of accumulation and blockage, and also reducing dust flying and improving the working environment.

[0038] Based on the above solutions, such as Figure 1-3 As shown in the embodiment of this utility model, both the first discharge port 32 and the second discharge port 33 are provided with discharge hoppers 70 at their outlet ends; specifically, the feed hopper 60 is funnel-shaped or cone-shaped to ensure that the filter cake can fall directly into the corresponding collection box 40, reducing the risk of accumulation and blockage.

[0039] Based on the above solutions, such as Figure 1-3 As shown, in one embodiment of this utility model, the upper inner wall of the discharge hopper 70 is provided with slide rails on both sides, and the slide rails are inserted with slide grooves. A filter plate 80 is fixedly connected to the side of the slide grooves. The filter plate 80 is provided with a handle. The filter plate 80 can effectively remove large particulate impurities in the filter cake and improve the purity of the material in subsequent processing. When it is necessary to clean or replace the filter plate 80, the operator can easily pull out the filter plate 80 through the handle for cleaning or replacement.

[0040] Based on the above solutions, such as Figure 5As shown in this embodiment of the present invention, the collection box 40 is provided with a movable wheel 41 at its bottom, and a handle 42 is provided on one side of the collection box 40 so as to move the collection box 40 by means of the handle 42; the bottom of the collection box 40 is connected to a drain pipe 43, and the interior of the collection box 40 is connected to the outside through the drain pipe 43. A valve is provided on the drain pipe 43, and the collection box 40 is provided with a filter hole 44. The collection box 40 is connected to the drain pipe 43 through the filter hole 44. The filter cake enters the collection box 40 through the discharge port. If the filter cake in the collection box 40 contains a certain amount of liquid, it will flow into the drain pipe 43 through the filter hole 44, and then the liquid will be discharged by controlling the valve.

[0041] Specifically, such as Figure 1-2 As shown in the embodiment of this utility model, the filter press mechanism 20 includes a thrust plate 21 disposed on one side of the frame 10, a pushing component 22 disposed on the other side of the frame 10, a pushing plate 23 connected to the output end of the pushing component 22, and a plurality of filter press plates 24 disposed between the thrust plate 21 and the pushing plate 23 and sliding on the frame 10. Each filter press plate 24 is provided with a water outlet pipe 25 on one side. The frame 10 is also provided with a water collection tank 26, which is located below the water outlet pipe 25, and a drain pipe 27 is provided on one side of the water collection tank 26.

[0042] In use, gallium-containing suspension enters the filter press mechanism 20 through a pump or other conveying device, forming filter chambers between each filter press plate 24. The pushing component 22 applies pressure to the filter press plate 24 through the pushing plate 23, forcing the liquid to be discharged through the filter medium on the filter press plate 24. The liquid flows into the water collection tank 26 through the water outlet pipe 25 and is finally discharged through the drain pipe 27. When the filter cake is formed, the gap between the filter press plates 24 is opened, allowing the filter cake to fall off and into the feed hopper 60. The pushing component 22 can be a hydraulic cylinder or an oil cylinder.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
