Description

Technical Field

[0001] This utility model relates to a filter press device, and more particularly to a filter press device for circulating water. Background Technology

[0002] In the refining process of non-ferrous metals such as zinc, slag water is produced. Water that falls into the factory area during rainy days also has a certain polluting property due to the adsorption of dust, especially zinc powder. It is necessary to strictly control the outflow of water from the production area and achieve recycling. Therefore, a filter press is needed to filter the water to realize the water recycling within the park.

[0003] For example, a non-ferrous metal smelting circulating water pressure filtration device, disclosed in Chinese Patent Publication No. CN216295462U, includes a base, a pressure tank, a pressure plate, a filter plate assembly, and a filter assembly. The pressure tank is located at the upper end of the base, and the side wall of the pressure tank is symmetrically provided with first locking holes. An inlet pipe is provided through the upper side of the first locking holes. The filter plate assembly includes a filter plate, which is slidably installed on the inner wall of the pressure tank. The outer wall of the filter plate is symmetrically provided with first grooves, and a first spring is provided in the first groove. The end of the first spring away from the first groove is connected to a first locking block. The filter plate assembly is connected to the pressure tank by the first locking block locking into the first locking hole. This utility model uses the elastic restoring action of the first spring to make the first locking block locking into or moving out of the first locking hole, thereby realizing convenient disassembly and assembly of the filter plate assembly, which is convenient for cleaning and replacement.

[0004] Some problems were found when using the existing non-ferrous metal smelting circulating water pressure filter. First, after the pressure plate moves down to below the inlet pipe, the circulating water will be directly transported to the top of the pressure plate through the inlet pipe. To avoid this, the transport of circulating water needs to be blocked during the pressure filtration process. After the pressure plate is reset, the transport of circulating water through the inlet pipe needs to be restored. This makes the continuous operation during continuous pressure filtration quite cumbersome. Utility Model Content

[0005] The purpose of this invention is to provide a circulating water pressure filter device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating water pressure filtration device, comprising an inlet tank, a filter tube embedded in the inlet tank, a piston slidably installed in the filter tube, an electro-hydraulic telescopic rod fixedly connected to one side of the piston, the electro-hydraulic telescopic rod fixedly connected to the inlet tank, water inlets fixedly connected to both the upper and lower surfaces of the filter tube located inside the inlet tank, a filter frame connected to the other end of the filter tube, a filter mechanism fixedly connected inside the filter frame, a squeezing tube connected to the other end of the filter frame, and a collection tank provided below the squeezing tube.

[0007] Preferably, an inlet connector is fixedly connected to the front of the inlet tank, a drain head is fixedly connected to the front of the collection tank, and a support column is fixedly connected to the bottom of the inlet tank.

[0008] Preferably, a fixing ring is fixedly connected to the filter tube and the extrusion tube, and a fixing protrusion is fixedly connected to one side of the fixing ring.

[0009] Preferably, a connecting ring is fixedly connected to the outer wall of the filter frame near the two ends, and an insertion limiting hole is provided in the connecting ring, which cooperates with the fixed protrusion.

[0010] Preferably, the filter tube is fixed with fixing feet at both the front and back near the end, and a connecting stud is fixed to one side of the fixing foot, with a fixing nut threaded onto the connecting stud.

[0011] Preferably, the front and rear ends of the fixing ring on the extrusion tube are fixedly connected to connecting ears, the connecting ears cooperate with connecting studs, and the end of the extrusion tube is fixedly connected to a connecting flange.

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

[0013] 1. The inlet tank can temporarily store the circulating waste liquid that needs to be filtered. During the process of pressing and filtering by starting the electric hydraulic telescopic rod to drive the piston, the wastewater output through the inlet connector will be stored inside the inlet tank. When the electric hydraulic telescopic rod drives the piston to reset, the wastewater stored inside the inlet tank can then enter the filter tube again through the inlet. The pressing and filtering operation can be performed intermittently. Compared with the existing device, it does not require interruption of wastewater delivery, making the operation more convenient.

[0014] 2. By unscrewing the fixing nut, the compression of the extrusion tube can be released. At this time, the extrusion tube can move outward by a certain distance, so that the filter frame between the filter tube and the extrusion tube has a certain amount of room to move. This allows the fixing protrusion to move out of the insertion limiting hole, and the filter frame can be removed vertically to facilitate replacement or cleaning of the filter mechanism.

[0015] 3. The set collection tank can collect and store the filtered circulating water. Since there is a certain height difference between the squeezing pipe and the collection tank, the circulating water can be effectively prevented from being sucked back into the interior during the piston's backward repositioning process.

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a circulating water pressure filtration device, including an inlet tank 1, a filter tube 3 embedded in the inlet tank 1, a piston 201 slidably installed in the filter tube 3, an electric hydraulic telescopic rod 2 fixedly connected to one side of the piston 201, the electric hydraulic telescopic rod 2 fixedly connected to the inlet tank 1, water inlets 301 fixedly connected to both the upper and lower surfaces of the part of the filter tube 3 located inside the inlet tank 1, a filter frame 4 connected to the other end of the filter tube 3, a filter mechanism 401 fixedly connected inside the filter frame 4, a squeezing tube 5 connected to the other end of the filter frame 4, and a collection tank 6 provided below the squeezing tube 5.

[0022] In this implementation scheme, a certain amount of wastewater to be filtered is injected into the inlet tank 1. The wastewater flows into the filter tube 3 through the inlet 301. The electric hydraulic telescopic rod 2 is activated to move the piston 201. The movement of the piston 201 squeezes the wastewater inside the filter tube 3. The squeezing action of the piston 201 forces the wastewater through the filtration mechanism 401. After filtration by the filtration mechanism 401, the wastewater is transported to the squeezing pipe 5 and discharged into the collection tank 6 for temporary storage. Subsequently, the electric hydraulic telescopic rod 2 is activated to reset the piston 201. When the piston 201 moves back to behind the inlet 301, the wastewater stored in the inlet tank 1 will re-enter the filter tube 3 through the inlet 301. This process is repeated, thus enabling uninterrupted filtration of wastewater. The inlet tank 1 and the collection tank 6 serve as a buffer container for the temporary storage of circulating water. During the wastewater pressure filtration process, the wastewater is temporarily stored inside the inlet tank 1, allowing for uninterrupted supply of wastewater to the device without needing to stop the wastewater supply according to the pressure filtration steps.

[0023] In order to achieve the purpose of connecting the water supply pipeline, the device adopts the following technical solution: the inlet tank 1 is fixedly connected to the front of the inlet connector 101, the collection tank 6 is fixedly connected to the front of the drain head 601, the inlet tank 1 is fixedly connected to the bottom of the support column 102, the filter tube 3 and the squeezing tube 5 are fixedly connected to the fixing ring 7, and the fixing ring 7 is fixedly connected to the side of the fixing protrusion 701.

[0024] The inlet connector 101 connects to the delivery pipe, and the outlet connector 601 connects to the outlet pipe, so that the circulating water can be delivered into the device and discharged in time. The support column 102 is used to connect to the inlet tank 1, so that there is a height difference between the inlet tank 1 and the collection tank 6, so that the filtered circulating water will not be drawn back into the inlet tank 1 during the process of the piston 201 moving backward and resetting.

[0025] To facilitate the disassembly of the filter frame 4, the device employs the following technical solution: a connecting ring 402 is fixedly attached to the outer wall of the filter frame 4 near both ends. The connecting ring 402 has an insertion limiting hole 403, which cooperates with the fixing protrusion 701. The filter tube 3 has fixing feet 302 fixedly attached to both the front and back near the end. A connecting stud 303 is fixedly attached to one side of the fixing foot 302. A fixing nut 304 is threaded onto the connecting stud 303. The pressing tube 5 has connecting ears 502 fixedly attached to the front and back of the fixing ring 7, which cooperates with the connecting stud 303. A connecting flange 501 is fixedly attached to the end of the pressing tube 5.

[0026] By using the connecting lug 502 and the connecting stud 303 to cooperate, the extrusion tube 5 and the filter tube 3 are connected together. After screwing on the fixing nut 304, the fixing nut 304 will squeeze the connecting lug 502, so that the extrusion tube 5 does not approach the end of the filter tube 3. The filter frame 4 is located between the filter tube 3 and the extrusion tube 5. The extrusion tube 5 can then clamp and fix the filter frame 4. At the same time, the insertion limiting hole 403 and the fixing protrusion 701 cooperate to limit the position of the filter frame 4, thereby effectively fixing the filter frame 4 between the filter tube 3 and the extrusion tube 5. When it is necessary to clean the filter mechanism 401 inside the filter frame 4, simply unscrew the fixing nut 304 to widen the distance between the extrusion tube 5 and the filter tube 3, so that the fixing protrusion 701 moves out of the insertion limiting hole 403. The filter frame 4 can then be removed vertically to facilitate the replacement or cleaning of the filter mechanism 401.

[0027] The working principle and usage process of this utility model are as follows: During use, the drain head 601 and the inlet connector 101 need to be connected to the discharge and input pipes respectively. First, a certain amount of wastewater to be filtered is discharged into the inlet tank 1 through the inlet connector 101. The wastewater will flow into the filter tube 3 through the inlet 301. The electric hydraulic telescopic rod 2 is activated to move the piston 201. The movement of the piston 201 will squeeze the wastewater inside the filter tube 3. The squeezing action of the piston 201 forces the wastewater through the filtration mechanism 401. After filtration by the filtration mechanism 401, the wastewater is transported to the squeezing pipe 5 and temporarily stored in the collection tank 6. During the forward movement of the piston 201 for filtration, the circulating wastewater will be temporarily stored inside the inlet tank 1, without interrupting the wastewater supply. After filtration is completed, the electric hydraulic telescopic rod 2 is activated to reset the piston 201. At this time, the wastewater stored inside the inlet tank 1 can re-enter the filter tube 3 through the inlet 301. Repeating the above operation allows for uninterrupted filtration of circulating wastewater.
