[0022] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.
[0023] Please refer to Figures 1-7. In this embodiment of the present invention, a dual-working-zone filter press includes a frame 1 and a support base 6. A support leg 101 is fixedly provided at the bottom of the frame 1 to provide stable support. The frame 1 has two working zones: one for filtering coal mine wastewater and the other for unloading and cleaning. Continuous alternating filtration and unloading can be performed without stopping the machine, eliminating downtime. Furthermore, several filter plates 2 are slidably arranged inside each working zone. Filter cloth 201 is provided inside each filter plate 2, and sealing gaskets are embedded on the sides of the filter plates 2 to ensure... To ensure a tight seal between adjacent filter plates 2 and prevent leakage, a thrust plate 3 is fixedly installed on one side of the working area. This plate can limit the position of the filter plate 2 after it is pushed. The support base 6 is fixedly connected to the support leg 101 via a fixing frame. A mounting frame 4 is slidably installed on the top of the support base 6. A pressing cylinder 401 is fixedly installed on the top of the mounting frame 4. A pressing plate 5 is fixedly installed on the piston end of the pressing cylinder 401. The middle part of the frame 1 near the pressing plate 5 is shorter than the sides, which can limit the position of the pressing plate 5 when it moves left and right, thereby making the pressing plate 5 correspond to the working area.
[0024] In this embodiment, preferably, an installation rod 202 is fixedly provided on the side of the top of the filter plate 2, a guide seat 203 is fixedly provided at the end of the installation rod 202, a guide groove 102 is fixedly provided at the top of the frame 1, and the guide seat 203 slides in the guide groove 102. The sliding cooperation between the guide seat 203 and the guide groove 102 can guide the movement of the filter plate 2.
[0025] In this embodiment, preferably, a guide rod 204 is fixedly provided inside the guide groove 102, a guide hole corresponding to the guide rod 204 is provided in the middle of the guide seat 203, and a reset spring 205 sleeved on the outside of the guide rod 204 is installed between adjacent guide seats 203. When the pressing plate 5 squeezes the filter plate 2, it can compress the reset spring 205. After the pressing plate 5 releases the pressing on the filter plate 2, the filter plate 2 can be reset under the elastic force of the reset spring 205.
[0026] In this embodiment, preferably, a feed pipe 301 is fixedly provided in the middle of one side of the thrust plate 3, and a control valve 302 is provided on the surface of the feed pipe 301. The operation of the feed pipe 301 can be controlled by the control valve 302. A connecting pipe 303 is fixedly provided at the ends of the two feed pipes 301. The connecting pipe 303 is connected to the discharge end of the external sewage pump. The sewage pump can be used to pass external coal mine sewage into the filter plates 2.
[0027] In this embodiment, preferably, a drain pipe 501 is fixedly provided at the bottom of the outer side of the pressing plate 5, which can quickly discharge the filtered sewage through the drain pipe 501.
[0028] In this embodiment, preferably, a slide rail 604 is fixedly provided at the top of the support base 6, and a slide block 403 is fixedly provided at the bottom of the mounting frame 4. The slide block 403 and the slide rail 604 are slidably connected, and the sliding connection between the slide block 403 and the slide rail 604 guides the movement of the mounting frame 4.
[0029] In this embodiment, preferably, a transmission gear plate 402 is fixedly provided at the bottom of the mounting frame 4, a motor frame 601 is fixedly provided at the top of the support base 6, a drive motor 602 is fixedly provided at the top of the motor frame 601, a transmission gear 603 is fixedly provided on the transmission shaft of the drive motor 602, the transmission gear 603 is meshed with the transmission gear plate 402, the drive motor 602 drives the transmission gear 603 to rotate, and under the meshing cooperation of the transmission gear 603 and the transmission gear plate 402, the mounting frame 4 is moved, so that the pressing plate 5 corresponds to the working area.
[0030] In use, first connect the connecting pipe 303 to the discharge end of the sewage pump, then open the corresponding control valve 302 and start the drive motor 602. The drive motor 602 drives the transmission gear 603 to rotate. Under the meshing of the transmission gear 603 and the transmission gear plate 402, the mounting frame 4 moves laterally. Adjust the position of the pressing plate 5 so that it corresponds to one of the working areas. Then start the pressing cylinder 401. The extension end of the pressing cylinder 401 extends and drives the pressing plate 5 to move closer to the filter plate 2, so that the adjacent filter plates 2 are pressed tightly together. After the filter plates 2 move, the return spring 205 can be compressed. Then start the sewage pump. The sewage pump injects coal mine sewage into the space between the filter plates 2. The filter cloth 201 can filter impurities in the wastewater. The filtered wastewater is discharged through the drain pipe 501 at the bottom of the pressing plate 5. The impurities form a filter cake between adjacent filter plates 2. Then, the extension end of the pressing cylinder 401 is controlled to retract, so that the pressing plate 5 is reset. Under the elastic action of the reset spring 205, each filter plate 2 is reset. The operator unloads and cleans the filter cake between adjacent filter plates 2. Then, the drive shaft of the drive motor 602 is controlled to rotate in the opposite direction, so that the pressing plate 5 can move to the position corresponding to another working area. The above steps are repeated to perform the pressing and filtration work. By utilizing the cooperation of the two working areas, the pressing and filtration work can be performed alternately without stopping the machine, thus eliminating downtime.
[0031] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
