Description

Technical Field

[0001] This utility model relates to the field of filtrate technology, and in particular to a filtrate filtration device. Background Technology

[0002] Mining requires a large amount of water. To save water, multi-stage sedimentation tanks are generally used to settle the mine return water and reduce pollution. Then, filtration equipment is used to further filter and purify the settled mine return water before it is sent back to the ore dressing plant for reuse.

[0003] The existing document CN215692149U discloses a main frame for a landfill leachate filtration device, including a device body with a hollow columnar structure. Inside the device body is a filtration mechanism for filtering landfill leachate. Interconnected insertion slots are provided on the sides and inner walls of the device body. The filtration mechanism includes an outer frame and a filter screen, with the filter screen detachably installed inside the outer frame. The outer frame is inserted into the device body through the insertion slots on its side. During landfill treatment, the outer frame can be pulled out from the side of the device body, facilitating regular cleaning of the filter screen and ensuring filtration efficiency. This device achieves step-by-step filtration of landfill leachate, resulting in better filtration. Furthermore, the filtered residue is classified according to particle size for convenient subsequent processing.

[0004] The structure of this device is similar to existing mine filtration equipment. After a period of use, the equipment needs to be shut down and the filter screen needs to be removed and cleaned, which delays the filtration and purification of mine return water.

[0005] Therefore, it is necessary to provide a filtrate filtration device to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a filtrate filtration device that can maintain and clean the filter plate without stopping the equipment.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0024] Example 1:

[0025] like Figure 1-3 As shown, the filtrate filtration device provided by this utility model includes: a housing 1, with an inlet pipe 2 installed on the top of the housing 1 and a drain pipe 3 installed on the side. The inlet pipe 2 is connected to the outlet of the sedimentation tank for mine return water, and the drain pipe 3 is connected to the inlet of the water supply for the mineral processing plant. Multiple detachable filter plates 4 are sealed and installed on the housing 1. In this embodiment, four filter plates 4 are described. From left to right, the first and third filter plates 4 have the same model, and the second and fourth filter plates 4 have the same model. A switching mechanism is also provided on the housing 1. The switching mechanism includes a first insert plate 5, a second insert plate 6, and an electric push rod 7. The first insert plate 5 and the second insert plate 6 are sealed and inserted into the housing 1. The electric push rod 7 can drive the first insert plate 5 and the second insert plate 6 to move horizontally. A first partition is fixedly installed inside the housing 1. Plate 11 and multiple second partition plates 12, first insert plate 5, second insert plate 6, first partition plate 11 and multiple second partition plates 12 divide the interior of the box 1 into an inlet buffer chamber 8, an outlet buffer chamber 9 and multiple filter chambers 10. Each filter chamber 10 has a sealing door 17 installed on its back. In this embodiment, there are four filter chambers, with four filter plates 4 installed obliquely in the four filter chambers 10 respectively. It is worth noting that the contact points between the first insert plate 5, second insert plate 6 and the first partition plate 11, second partition plate 12 are sealed with sealing strips or sealing rings, thus preventing the inlet buffer chamber 8, outlet buffer chamber 9 and multiple filter chambers 10 from communicating with each other. An inlet hole 13 and an outlet hole 14 are installed on the first insert plate 5, and a connecting pipe 15 is installed at the bottom of the second insert plate 6. Figure 2As shown, through the inlet hole 13, outlet hole 14, and connecting pipe 15, sewage in the inlet buffer chamber 8 can enter the second filter chamber 10 through the inlet hole 13, then enter the fourth filter chamber 10 through the connecting pipe 15, and then enter the outlet buffer chamber 9 through the outlet hole 14, and be discharged through the drain pipe 3. In this case, the filter plates 4 in the first and third filter chambers 10 do not participate in filtration. When the filter plates 4 in the second and fourth filter chambers 10 need to be cleaned, the electric push rod 7 is activated, causing the first insert plate 5 and the second insert plate 6 to... Moving to the left, the inlet 13 and outlet 14 are positioned above the first and third filter chambers 10, respectively, and the connecting pipe 15 connects the bottoms of the first and third filter chambers 10. At this point, the wastewater will be filtered through the first and third filter chambers 10, bypassing the second and fourth filter chambers 10. The filter plates 4 of the second and fourth filter chambers 10 can be pulled outwards and removed for cleaning. Then, the sealing doors 17 on the back of the second and fourth filter chambers 10 can be opened to flush and clean them. In this operating mode, the equipment does not need to be stopped. By using a rotating system to filter mine return water, continuous operation of the equipment can be achieved without delaying the filtration and purification of the mine return water.

[0026] By setting up a housing 1, multiple filter plates 4, and a switching mechanism including a first insert plate 5, a second insert plate 6, and an electric push rod 7, the first insert plate 5 and the second insert plate 6 can be moved by the electric push rod 7, thereby changing the sewage flow path in the housing 1. Without stopping the equipment, it is convenient to clean and maintain the filter plates 4 and the filter chamber 10 that do not participate in filtration, so as not to delay the filtration and purification of mine return water.

[0027] Example 2:

[0028] like Figure 1-2 As shown, the filter plate 4 is installed at an angle inside the filter chamber 10. In this way, the filtration area of ​​the filter plate 4 can be further increased, and the sediment will accumulate on one side along the filter plate 4, thereby slowing down the speed at which the filter plate 4 is completely blocked, reducing its maintenance frequency, and thus facilitating maintenance operations.

[0029] By installing the filter plate 4 at an angle inside the filter chamber 10, the frequency of maintenance of the filter plate 4 can be reduced, which is beneficial for maintenance work.

[0030] Example 3:

[0031] like Figure 2 As shown, two limiting blocks 16 are installed at the bottom of the housing 1. The limiting blocks 16 are located on both sides of the connecting pipe 15. A rubber buffer pad is installed on the side of the limiting blocks 16 facing the connecting pipe 15. When in use, when the connecting pipe 15 moves left and right with the second insert plate 7, it cannot continue to move when it hits the limiting block 16, thus limiting the stroke of the electric push rod 7.

[0032] By installing two limit blocks 16 at the bottom of the housing 1, the stroke of the electric push rod 7 can be easily controlled, thus playing a limiting role.

[0033] Example 4:

[0034] like Figure 2-3 As shown, the filter plate 4 includes a frame 40 and a filter screen 41 installed in the middle of the frame 40. A sealing ring 42 is also installed on the frame 40, which is used to seal between the frame 40 and the housing 1. The frame 40 and the second partition plate 12 are slidably and sealingly connected. A handle is also installed on one side of the frame 40 for easy use of the filter plate 4. The filter screen 41 can be selected with different filtration levels according to filtration requirements.

[0035] Filtration can be facilitated by setting a filter plate 4 that includes a frame 40 and a filter screen 41.

[0036] Working principle: During use, the sewage in the inlet buffer chamber 8 enters the second filter chamber 10 through the inlet hole 13, then flows into the fourth filter chamber 10 through the connecting pipe 15, and then enters the outlet buffer chamber 9 through the outlet hole 14, and is discharged through the drain pipe 3. In this case, the filter plates 4 in the first and third filter chambers 10 do not participate in filtration. When the second and fourth filter chambers 10 and the filter plates 4 need to be cleaned, the electric push rod 7 is activated, causing the first insert plate 5 and the second insert plate 6 to move to the left. The inlet 13 and the outlet 14 move to the top of the first and third filter chambers 10 respectively. The connecting pipe 15 connects the bottom of the first and third filter chambers 10. At this time, the sewage will be filtered through the first and third filter chambers 10 and will no longer pass through the second and fourth filter chambers 10. The filter plates 4 of the second and fourth filter chambers 10 are pulled outward and removed for cleaning. Then the sealing door 17 on the back of the second and fourth filter chambers 10 is opened to rinse and clean the inside of the second and fourth filter chambers 10. Under this operating method, the equipment does not need to be stopped. It is used in rotation to filter the mine return water, which can achieve continuous operation of the equipment without delaying the filtration and purification of the mine return water.
