DETAILED DESCRIPTION

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0022] Reference Figure 1-6 As shown, a solid-liquid separation device for sludge treatment includes a separation box 1, a mounting plate 5 is fixedly connected at the middle position above the separation box 1, three sets of electric telescopic rods 6 are fixedly installed at the bottom of the mounting plate 5, the output end of the electric telescopic rod 6 is fixedly connected to a push plate 7, and the left and right sides of the push plate 7 are slidably connected to the scraper 8. Through the precise control of the electric telescopic rod 6, the positions of the push plate 7 and the scraper 8 can be flexibly adjusted to achieve effective scraping of the sludge on the surface of the filter plate 406. A partition 9 is fixedly connected at the middle position inside the push plate 7, and the left and right sides of the partition 9 are fixedly connected. Two sets of return springs 10, the ends of the return springs 10 are fixedly connected to the inner wall of the scraper 8. The design of the return springs 10 enables the scraper 8 to automatically reset after completing the scraping task, without the need for additional power or manual operation. Drain ports 2 are provided on the lower ends of the left and right sides of the separation box 1. Guide grooves 12 are fixedly connected to the positions of the drain ports 2 on the left and right sides of the separation box 1. The combined design of the guide grooves 12 and the drain ports 2 allows the squeezed water to flow out smoothly and be collected, reducing the accumulation and retention of water in the separation box 1, and improving the effect and efficiency of solid-liquid separation. At the same time, this design also facilitates the subsequent further processing or recycling of the collected water. The four corners of the bottom of the separation box 1 are fixedly connected with lifting components 11, and a separation component 4 is provided inside the separation box 1.

[0023] Specifically, the separation component 4 includes a first bidirectional screw rod 401 and a second bidirectional screw rod 402. The first bidirectional screw rod 401 is rotatably connected to the rear side of the separation box 1, and the second bidirectional screw rod 402 is rotatably connected to the front side of the separation box 1. The left and right ends of the first bidirectional screw rod 401 and the second bidirectional screw rod 402 are both threadedly connected to the extrusion frame 405, and the filter plate 406 is detachably connected to the inside of the two extrusion frames 405.

[0024] Specifically, the right end of the first bidirectional screw rod 401 passes through the right side wall of the separation box 1 and is fixedly connected to the first synchronous wheel 403, and the right end of the second bidirectional screw rod 402 passes through the right side wall of the separation box 1 and is fixedly connected to the second synchronous wheel 404. The first synchronous wheel 403 is connected to the second synchronous wheel 404 through a synchronous belt. The use of a synchronous belt to connect the first bidirectional screw rod 401 and the second bidirectional screw rod 402 ensures that the extrusion frames 405 on both sides can move synchronously and evenly, thereby achieving uniform extrusion of the sludge and improving the solid-liquid separation effect.

[0025] Specifically, a servo motor 407 is fixedly installed on the left side of the separation box 1 , and the output end of the servo motor 407 passes through the left side plate of the separation box 1 and is fixedly connected to the left end of the second bidirectional screw rod 402 .

[0026] Specifically, the lifting assembly 11 includes a support leg 1101 fixedly connected to the bottom of the separation box 1 , a chamber 1102 is defined at the lower portion of the support leg 1101 , and a square limiting rod 1103 is fixedly connected to the top wall of the chamber 1102 .

[0027] Specifically, the bottom of the support leg 1101 is rotatably connected to a drive disk 1105, the middle part of the drive disk 1105 is threadedly connected to a threaded rod 1104, the bottom end of the square limit rod 1103 extends into the interior of the threaded rod 1104 and is slidably connected to the threaded rod 1104, and the bottom of the threaded rod 1104 is fixedly connected to the universal moving wheel 1106. By rotating the drive disk 1105 in the threaded matching relationship, the threaded rod 1104 will not rotate under the restriction of the square limit rod 1103, thereby allowing the threaded rod 1104 to extend outward to achieve height increase.

[0028] Specifically, a mud discharge port 13 is provided at the middle position of the bottom surface of the separation box 1, and a baffle 3 is slidably connected to the inside of the mud discharge port 13. The design of the mud discharge port 13 facilitates the discharge of sludge after treatment, and the setting of the baffle 3 can prevent the outflow of sludge when necessary, thereby realizing precise control of sludge discharge.

[0029] Working principle: First, pour the sludge into the separation box 1, then the servo motor 407 drives the second bidirectional screw 402 to rotate, and the first bidirectional screw 401 is synchronously driven to rotate through the second synchronous wheel 404, the synchronous belt and the first synchronous wheel 403. Under the threaded fitting relationship, the squeezing frames 405 on both sides move toward each other to squeeze the sludge and squeeze out the water in the sludge. After moving to a certain extent, the squeezing frames 405 on both sides will abut against the scraper 8, thereby preventing the sludge from overflowing from above the squeezing frame 405. As the squeezing frame 405 moves The scraper 8 will retract into the push plate 7 until the other end of the scraper 8 abuts against the partition 9. The squeezed water will flow out from the small holes in the filter plate 406 and flow into the drain outlet 2 into the guide groove 12. After the sludge extrusion is completed, the baffle 3 at the sludge outlet 13 is pulled out, and part of the sludge will automatically fall from the sludge outlet 13 under the action of gravity. The output end of the electric telescopic rod 6 extends and pushes the push plate 7 and the scraper 8 to move, thereby scraping off the sludge adhering to the surface of the filter plate 406. After that, the components are reset for the next separation, and the reset spring 10 can realize the reset of the scraper 8.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
