Description

Technical Field

[0001] This utility model relates to the technical field of filters, specifically to a horizontal multi-core double-row filter. Background Technology

[0002] Coal mine drilling rigs consume a large amount of water during production operations, and the water quality requirements are quite strict. After being used by the drilling rig, the water produces wastewater with a high concentration of impurities. This wastewater, due to its high content of impurities such as peat, easily causes sedimentation and blockages. Furthermore, the limited space and large volume of wastewater exacerbate the problem, leading to severe siltation and difficult wastewater treatment. Traditionally, to address the serious problem of wastewater accumulation and blockage in drainage channels, regular manual cleaning is used. However, this method is time-consuming, labor-intensive, and increases the workload and labor costs for workers; moreover, it results in significant water waste.

[0003] To address the aforementioned issues, patent "CN117959827A" discloses "a static, slow-flowing, meandering, contacting, and settling circulation system for coal and water in a drilling rig," comprising a sedimentation separation component and a filtration component. The sedimentation separation component separates high-concentration water from the coal mine drilling wastewater collection tank. The separated water is then filtered by the filtration component to obtain purified water, which can then be reused. However, the filtration component uses a common cylindrical sintered mesh filter element, which limits the filter element area and backwashing effect, thereby limiting the purification efficiency of the separated water.

[0027] like Figure 1-5As shown, this utility model discloses a horizontal multi-core double-row filter, including a base 1. The upper end of the base 1 is connected to a cylindrical horizontal filter tank 2 via a bracket. The internal space of the filter tank 2 is divided into an inlet space 4 and a filtration space 5 by an isolation seat 3. An inlet connector 6 and an outlet connector 7 are connected to the outer side of the filter tank 2. The inlet connector 6 communicates with the inlet space 4, and the outlet connector 7 communicates with the filtration space 5. The filtration space 5 is provided with a filter assembly one and a filter assembly two. Both component one and filter assembly two include several annularly distributed pleated filter elements 8. One end of each pleated filter element 8 is connected to the seat hole of the isolation seat 3, and the other end passes through the bottom surface of the filter tank 2 and is fixed by a clamp. Each pleated filter element 8 includes an upper sealing seat 81 and a lower sealing seat 82. Between the upper sealing seat 81 and the lower sealing seat 82, there is an outer cylindrical outer skeleton protective net 83 located on the outside and an inner cylindrical inner skeleton protective net 84 located on the inside. A filter screen 85 is provided between the outer skeleton protective net 83 and the inner skeleton protective net 84. The filter screen 85 is composed of several W-shaped filter sections. A first support frame 86 is provided in the V-shaped space formed by the filter screen 85 and the inner skeleton mesh 84. A second support frame 87 is provided in the V-shaped space formed by the filter screen 85 and the outer skeleton mesh 83. The folded filter element 8 communicates with the liquid inlet space 4 through a seat hole. A seat hole switch valve is provided in the seat hole. A rotating pipe 9 is located at the axis of the liquid inlet space 4. One end of the rotating pipe 9 passes through the filter tank 2 and is connected to a motor 10 with a speed reducer; the other end is rotatably connected to the isolation seat. The filter space 5 is equipped with a main drain pipe 13. One end of the main drain pipe 13 is connected to the bushing and communicates with the rotating pipe 9. The other end passes through the filter tank 2 and is equipped with an electric ball valve 11. A drain branch pipe 12 is connected to the rotating pipe 9 located in the liquid inlet space 4. One end of the drain branch pipe 12 is equipped with a seat hole connector that matches the seat hole. The bottom end of the liquid inlet space 4 is connected to the output end of the main drain pipe 13 through a second drain branch pipe 14. A drain switch valve is provided on the second drain branch pipe 14.

[0028] In one specific embodiment of this application, the upper four corners of the base 1 are provided with lifting lugs to facilitate the hoisting of the entire device. Furthermore, wheels can be installed at the lower end of the base 1 to facilitate the movement and adjustment of the position of the entire device.

[0029] In a specific embodiment of this application, there are two liquid outlet connectors 7 symmetrically distributed on the outer side of the filter tank 2, and two liquid inlet connectors 6 symmetrically distributed on the outer side of the filter tank 2. Depending on the requirements, one liquid inlet connector 6 (one liquid outlet connector 7) or two liquid inlet connectors 6 (two liquid outlet connectors 7) can be connected.

[0030] In a specific embodiment of this application, filter assembly one is located on the outer circle side of filter space 5, and filter assembly two is located on the inner circle side of filter space 5. Both are composed of several pleated filter elements 8 arranged in a ring. Due to their distribution position, the diameter of the pleated filter element 8 in filter assembly one is larger than the diameter of the pleated filter element 8 in filter assembly two. Filter assembly one and filter assembly two are arranged concentrically so that when the rotating pipe 9 is rotated at a certain angle, the seat hole connector (including two connectors, one large and one small) on the sewage branch pipe one 12 can be aligned with the pleated filter element 8 in filter assembly one and the pleated filter element 8 in filter assembly two, which are located at the same angle.

[0031] In a specific embodiment of this application, a constant pressure check valve is provided in both the liquid inlet connector 6 and the liquid outlet connector 7. The constant pressure check valve can increase the pressure inside the equipment cavity, thereby enhancing the backwashing function of the equipment.

[0032] In a specific embodiment of this application, the filter screen 85 preferably adopts a five-layer sintered filter screen, which is formed into the filter element liner by a hydraulic press under the support of a special mold. According to the direction of fluid, a spring skeleton is added and fitted between the filter screen 85 and the outer skeleton guard 83 and the inner skeleton guard 84 to further enhance the pressure resistance of the filter screen 85. The folded structure of the filter screen 85 can provide a larger filtration area (the area of ​​a single filter element is more than 2.4 times larger than that of a traditional filter element), and can achieve a more efficient filtration effect within the limited space inside the filter element.

[0033] In one specific embodiment of this application, a pressure gauge and a pressure sensor are installed on the filter tank 2 to monitor the inlet and outlet pressures of the equipment.

[0034] In a specific embodiment of this application, the electronic control host 16 controls the seat hole switch valve to open, and the liquid enters the inlet space 4 sequentially from the pipe and the inlet connector 6, and then enters the pleated filter element 8 through the seat hole for filtration. The filtered clean water flows downstream sequentially through the filtration space 5, the outlet connector 7, and the pipe, thereby completing the filtration function of the multi-core filter.

[0035] In a specific embodiment of this application, after a period of filtration, impurities in the liquid deposit on the filter screen, reducing its filtration efficiency. This results in a pressure difference between the liquid inlet (inlet space 4) and the liquid outlet. The specific pressures at both ends can be monitored in real time by the inlet pressure sensor and the outlet pressure sensor. When the pressure difference between the liquid inlet and outlet reaches a certain value (0.5 MPa), the pleated filter element 8 needs to be backwashed. The pressure sensor transmits information to the control unit 16, which controls the electric ball valve 11 to open automatically. The motor 10 controls the rotating tube 9 to rotate a certain angle, aligning the seat connector with a set of pleated filter elements 8. Under the action of the pressure difference, the pleated filter elements 8 are backwashed one by one. The contaminants on the inside are backwashed off under the reaction force and discharged sequentially through the drain branch pipe 12, the rotating pipe 9, and the main drain pipe 13. After the backwashing process ends, the electric ball valve 11 automatically closes, and the equipment enters the normal filtration state (the filter can still maintain continuous filtration during the backwashing process). Furthermore, while performing backwashing, the drain switch valve on the drain branch pipe 14 can be opened, and the contaminants and debris deposited in the liquid inlet space 4 will be discharged through the drain branch pipe 14 and the main drain pipe 13. During the discharge of contaminants and debris in the liquid inlet space 4, the adsorption force between the seat hole joint and the isolation seat is reduced, thereby reducing the torque between the drain branch pipe 1 and the motor, which is conducive to the rotation operation of the drain branch pipe 1 and the seat hole joint for sequential backwashing.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
