[0024] like Figure 1-4 , Figure 6 and Figure 8 As shown:

[0025] The invention comprises a frame 101, a fixed rod 401 and a moving block 205, wherein two L-shaped rods 104 are fixedly connected to the frame 101, two cylindrical rods are fixedly connected to the moving block 205, a filter cloth 201 is fixedly connected between the two cylindrical rods, a through groove is provided on the frame 101, and the filter cloth 201 can pass through the through groove, each L-shaped rod 104 is slidably connected to a pressure rod 301, a first compression spring is fixedly connected between each L-shaped rod 104 and the pressure rod 301, a slider 402 is slidably connected to the fixed rod 401, and an extrusion portion is slidably connected to the slider 402 403, the extrusion part 403 can enter the interior of the frame 101, the moving block 205 is slidably connected to a transverse rod, the transverse rod is fixedly connected with a first motor, the output shaft of the first motor is fixedly connected with a first lead screw, the first lead screw is threadedly connected to the moving block 205, in order to facilitate the observation of other structures in the figure, the longer transverse cylinder is not shown, the fixed rod 401 is fixedly connected with a second motor, the output shaft of the second motor is fixedly connected with a second lead screw, the second lead screw is threadedly connected to the slider 402, and the first compression spring can provide a downward elastic force for the compression rod 301.

[0026] The sludge to be subjected to the filter press separation operation is added into the frame 101, and the sludge added into the frame 101 is supported by the filter cloth 201, so that the sludge is stably placed in the frame 101, and then the squeezing part 403 is operated to slide back and forth on the slider 402, and the slider 402 is coordinated to move back and forth on the fixed rod 401, and then the squeezing part 403 is used to squeeze the sludge in the frame 101, so that the water in the sludge seeps through the filter cloth 201, and then the filter press treatment effect of the sludge is completed. In actual use, the filter The cloth 201 can be divided into three parts: left, middle and right. After the squeezing part 403 is continuously pressed down and the sludge oil-containing filter is pressed for a period of time, the moving block 205 can be operated to slide on the crossbar to move out a part of the filter cloth 201 originally located in the frame 101, and at the same time, an unused part of the filter cloth 201 is moved to the inside of the frame 101, and the filter pressing operation is continued, so as to achieve the effect of regularly and automatically replacing the filter part, thereby maintaining the filtering effect of the sludge oil-containing filter for a long time and ensuring the filtering performance;

[0027] At the same time, during the filtering operation, the two pressure rods 301 are always subjected to the elastic force of the two first compression springs to provide downward pressure, and then press against the two sides of the filtering part of the filter cloth 201, so that the filter cloth 201 inside the frame 101 can be in a tensioned posture, thereby ensuring that during the filter pressing process, the filter cloth 201 can provide stable support force, providing convenience for subsequent extrusion and filtering operations, that is, the present equipment can continuously maintain the tensioned posture of the filter cloth 201 during the filter pressing separation of oil-containing sludge, thereby ensuring the separation effect.

[0028] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown:

[0029] Each pressure rod 301 is slidably connected with a telescopic head 302, and the moving block 205 is fixed with trapezoidal rods A202, trapezoidal rods B203 and trapezoidal rods C204. The heights of trapezoidal rods A202, trapezoidal rods B203 and trapezoidal rods C204 gradually increase from left to right. The telescopic head 302 can contact with the trapezoidal rods A202, trapezoidal rods B203 and trapezoidal rods C204, and the pressure rod 301 is fixed with a first electric push rod that can push the telescopic head 302 to slide.

[0030] During the process of moving the moving block 205, the two telescopic heads 302 are slid out on the two pressure rods 301 until the two telescopic heads 302 can overlap with the trapezoidal rod A202, the trapezoidal rod B203 and the trapezoidal rod C204, and then the moving block 205 is operated to move, thereby ensuring that when the moving block 205 moves to replace the filtering part of the filter cloth 201, the two pressure rods 301 can be gradually pushed up by one of the trapezoidal rod A202, the trapezoidal rod B203 and the trapezoidal rod C204, and then separated from the filter cloth 201, ensuring that the normal movement process of the filter cloth 201 proceeds smoothly;

[0031] In actual use, two displacement sensors can be fixed to the frame 101 by bolts, and the moving ends of the two displacement sensors are respectively fixed to the two filter cloths 201, and then in the process of moving the moving block 205, the sliding of the two pressure rods 301 can be monitored to monitor whether the moving block 205 is sliding normally, and then when the power source driving the moving block 205 to slide fails, the situation can be discovered in time to achieve a self-inspection effect on the equipment, and at the same time, after the moving block 205 slides to the appropriate position, the two telescopic heads 302 are slid back, and then the two pressure rods 301 are used again to complete the tensioning effect of the filter cloth 201.

[0032] like Figure 3 As shown:

[0033] Each of the L-shaped rods 104 is slidably connected to a push rod 105 , and the two push rods 105 can respectively push the two pressure rods 301 to slide upward. Each of the L-shaped rods 104 is fixedly connected to a second electric push rod that can push the push rod 105 to slide.

[0034] When it is necessary to separate the two pressure rods 301 from the filter cloth 201 and to undertake the subsequent detection effect on the sliding of the moving block 205, the two push rods 105 can be operated to slide up, and then the two pressure rods 301 can be moved to the position where the two telescopic heads 302 can contact the trapezoidal rod A202, the trapezoidal rod B203 and the trapezoidal rod C204, and then the two telescopic heads 302 are operated to slide to facilitate the subsequent detection operation.

[0035] like Figure 2 and Figure 7 As shown:

[0036] The frame 101 further includes a supporting portion 103 slidably connected to the frame 101 , and a third electric push rod is fixedly connected to the frame 101 and can push the supporting portion 103 to slide.

[0037] Before the sliding moving block 205 is operated, the abutting portion 103 is first operated to slide upward, so that the abutting portion 103 is tightly abutted against the lower side of the filter cloth 201, and the abutting portion 103 cooperates with the frame 101 to restrict the filter cloth 201 inside the frame 101, ensuring that when the moving block 205 is subsequently operated to slide, the sludge inside the frame 101 is not easily moved at will, which provides convenience for the subsequent continuous sludge squeezing operation.

[0038] like Figure 2-3 As shown:

[0039] The slider 402 is connected to a sliding part 501, and a rotating rod 502 is rotatably connected to the sliding part 501. A cylindrical rod 404 is fixedly connected to the extrusion part 403. A second compression spring is fixedly connected between the slider 402 and the extrusion part 403. The rotating rod 502 can move the cylindrical rod 404 to slide. A first motor that can drive the rotating rod 502 to rotate is fixedly connected to the sliding part 501.

[0040] When using the extrusion part 403 for the extrusion and filtration operation, the operating rod 502 can be continuously rotated on the sliding part 501, so that the operating rod 502 can push the cylindrical rod 404 to slide up. When the operating rod 502 is rotated to a position separated from the cylindrical rod 404, the extrusion part 403 will slide down due to the elastic force of the second compression spring, so that the extrusion part 403 can complete the operation of accumulating force to slide down, so that the extrusion part 403 can perform an accumulated force to tap the sludge in the frame 101, thereby completing the filtration operation on the sludge. Subsequently, the slider 402 is operated to slide back and forth on the fixed rod 401, and the operating rod 502 is continuously rotated, so that the extrusion part 403 performs a comprehensive tapping operation on the sludge in the frame 101, thereby completing the subsequent comprehensive filtration and separation operation.

[0041] like Figure 4-6 and Figure 8 As shown:

[0042] The sliding part 501 is slidably connected to the slider 402, a contact head 503 is fixedly connected to the sliding part 501, a third compression spring is fixedly connected between the sliding part 501 and the slider 402, an electromagnetic block capable of adsorbing and fixing the sliding part 501 is fixedly connected to the slider 402, and the contact head 503 can contact the trapezoidal rod A202, the trapezoidal rod B203 and the trapezoidal rod C204.

[0043] When different parts of the trapezoidal rod A202, the trapezoidal rod B203 and the trapezoidal rod C204 contact the contact head 503, the sliding part 501 will slide to different distances on the slider 402, thereby changing the distance between the rotation center of the rotating rod 502 and the cylindrical rod 404, so that the rotating rod 502 can perform an upward toggle operation on the cylindrical rod 404 with different amplitudes, so that the squeezing part 403 can perform a sliding force accumulation process of different lengths, and then perform a force accumulation and slapping operation with different intensities on the sludge inside the frame 101, that is, by operating the sliding moving block 205, while being able to achieve the replacement of the filter part to maintain the filtering performance, the force accumulation and slapping force can also be adjusted so that the squeezing part 403 can perform a filter pressing operation with different intensities on the sludge, so as to facilitate the complete squeezing out of the water in the sludge and improve the filter pressing effect;

[0044] After the moving block 205 is moved to a suitable position, the electromagnetic block can be energized so that the electromagnetic block can fix the sliding part 501 after sliding, which brings convenience to the subsequent tossing operation.

[0045] like Figure 3 As shown:

[0046] The extrusion portion 403 is provided with a plurality of connection threaded holes, and a plate with protrusions of different shapes can be connected to the extrusion portion 403 by screwing bolts into the plurality of connection threaded holes.

[0047] The staff can connect a plate with protrusions of different shapes to the squeezing part 403 according to actual filtration needs, and then when the squeezing part 403 is used for tapping, the protrusions of different shapes are brought into contact with the sludge, thereby further improving the filtration efficiency of the sludge.

[0048] like Figure 1 As shown:

[0049] The invention also includes a guide portion 102 fixedly connected to the frame 101 .

[0050] The guide portion 102 can guide the sludge poured into the frame 101 so that all the sludge can enter the area where the filter cloth 201 is located, thereby facilitating subsequent filter pressing operations.

[0051] like Figure 8-9 As shown:

[0052] The frame 101 and the fixing rod 401 are both provided with a plurality of fixing threaded holes.

[0053] The frame 101 and the fixing rod 401 can be fixed by screwing bolts into a plurality of fixing threaded holes, thereby fixing the entire device.

[0055] Step 1: Add the sludge to be subjected to filter pressing and separation operation into the frame 101, and operate the rotating rod 502 to continuously rotate on the sliding part 501;

[0057] Step 3: Regularly operate the moving block 205 to slide on the horizontal rod. After the sliding operation of the moving block 205 is completed, energize the electromagnetic block to adsorb the sliding part 501;

[0058] Step 4: Then continue to rotate the rotating rod 502 until the sludge oil separation process is completed.
