Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to a solid-liquid separation treatment device for sludge. Background Technology

[0002] When performing solid-liquid separation on sludge, the sludge often contains lumpy sludge pieces. During solid-liquid separation of wastewater, the wastewater inside is difficult to separate completely, necessitating further separation. A search revealed that patent CN220098839U discloses a solid-liquid separation device for sludge. After the sludge is introduced into the separation cylinder through a conveyor, a hydraulic cylinder can be activated, causing the output end to extend downwards. Simultaneously, this drives a pressure plate to move downwards inside the separation cylinder, squeezing and dewatering the sludge to achieve solid-liquid separation. The wastewater flows out through filters on both sides and is discharged from the drain outlet. After solid-liquid separation is completed, the bottom of the discharge cover can be unlocked by unscrewing the locking rods on both ends and the right side of the bottom of the discharge cover downwards through the threaded holes. Then, the discharge cover can be flipped to the left using the hinge between the connecting foot and the inside of the fixing frame to open the inside of the separation cover and quickly discharge the sludge. However, this method, which separates solids and liquids by squeezing, is relatively fast, but the separation operation is cumbersome, and the subsequent cleaning of solid blocks is troublesome. Moreover, the structure is relatively complex. Therefore, a solid-liquid separation treatment device for sludge that is convenient to operate and has a simple structure is designed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 A sludge solid-liquid separation treatment device includes an inner cylinder 1 and an outer cylinder 3 fixedly fitted together. The top of the inner cylinder 1 is fixedly connected to a filter cloth 5 that is arc-shaped in a free state. The device also includes a lifting mechanism that drives the middle part of the filter cloth 5 to rise and fall. The bottom of the outer cylinder 3 is set with an inclined structure and a solid discharge port 4 is provided at the bottom end. A liquid discharge valve 2 is fixedly installed at the bottom of the inner cylinder 1.

[0023] Specifically, the lifting mechanism includes a lifting drive cylinder 7 vertically fixedly installed on the outer wall of the outer cylinder 3, and a lifting rod 6 vertically fixedly installed in the middle of the filter cloth 5. The top of the lifting rod 6 is fixedly connected to the top output end of the lifting drive cylinder 7 through a connecting rod 8. When the lifting drive cylinder 7 is started, the middle of the filter cloth 5 can be easily lifted up through the cooperation of the connecting rod 8 and the lifting rod 6.

[0024] Specifically, a feeding mechanism is also provided above the filter cloth 5. The feeding mechanism includes a sludge hopper 9 fixedly installed on the outer cylinder 3. A sludge valve 10 is fixedly installed at the bottom of the sludge hopper 9, which is located above the filter cloth 5 and on one side of the lifting rod 6 and connecting rod 8. The sludge hopper 9 is used to conveniently hold the sludge that needs to be separated into solid and liquid. By opening the sludge valve 10, the sludge can be conveniently dropped into the filter cloth 5.

[0025] Specifically, the bottom of the inner cylinder 1 is designed with an arc structure, and the drain valve 2 is fixedly connected to the lowest point of the arc structure to facilitate the drainage of mud.

[0026] Specifically, the top of the inner cylinder 1 is lower than the top of the outer cylinder 3 to prevent mud from splashing out.

[0027] Specifically, the bottom of the outer cylinder 3 also includes a support mechanism, which includes multiple support legs 11 fixedly installed at the bottom of the outer cylinder 3. The multiple support legs 11 facilitate the overall support of the device and make it easier to raise the height of the drain valve 2 and the solid discharge port 4.

[0028] When in use, pour a certain amount of sludge to be separated onto the filter cloth 5. The sludge lumps will remain inside the filter cloth 5, while the sludge liquid will fall into the inner cylinder 1 through the filter cloth 5. The sludge liquid can then be discharged by opening the drain valve 2. When the sludge lumps inside the filter cloth 5 accumulate to a certain amount, stop pouring the sludge to be separated onto the filter cloth 5. Use the lifting mechanism to lift the middle part of the filter cloth 5 upwards, so that the sludge lumps inside the filter cloth 5 fall into the outer cylinder 3. The sludge lumps will then be discharged from the drain port 4 at the bottom of the outer cylinder 3. After the sludge lumps inside the filter cloth 5 have been shaken off, use the lifting mechanism to lower and reset the filter cloth 5, and then continue the above operation.
