Description

Technical Field

[0001] The utility model relates to the technical field of sludge separation equipment, in particular to sludge separation equipment in sewage. Background Art

[0002] Sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment. Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering.

[0003] For example, the utility model patent with Chinese patent number: CN220609217U discloses a device for separating sludge from sewage, including a box body, a water inlet is arranged on one side of the box body, a water outlet is arranged on the other side of the box body, the water inlet and the water outlet are both far away from the bottom of the box body, a slot is arranged on the side of the box body adjacent to the above two sides, and a partition plate connected to the slot is installed on the slot; a coupling is also fixedly installed on the side of the box body with the water inlet, a servo motor is installed on the upper end of the coupling, a lead screw and a cross plate are installed inside the box body, and the output shaft of the servo motor and the lead screw are connected through a coupling synchronous belt, a screw hole is arranged in the middle of the cross plate, and the cross plate is threadedly connected to the lead screw through the screw hole; a mud discharge port is arranged at the bottom end of the side of the box body with the water outlet, and a sliding plate connected to the mud discharge port is installed on the surface of the mud discharge port. The separation of sewage and sludge by the partition solves the problem of draining all the water in the device first in the traditional technology, thereby producing a beneficial effect of reducing the cost of sewage treatment.

[0004] Although the above device can reduce the cost of sewage treatment, the sewage is very turbid, and it is not convenient for the staff to check the height of the sludge in the box. Therefore, the sludge in the box is treated regularly. The sewage and sludge in the box are separated into two parts by inserting a partition. When the sludge height in the box is low, there will be a large amount of sewage between the top surface of the sludge and the partition. When the sludge is subsequently discharged, the sewage will be discharged with the sludge, affecting the subsequent treatment of the sludge. The random discharge of untreated sewage will also have an impact on the environment. In addition, the manual operation of the partition increases the labor burden of the staff. Utility Model Content

[0005] The utility model discloses a sludge separation device in sewage, which solves the problem that when the sludge height in the box is low, a large amount of sewage will exist between the top surface of the sludge and the partition, and the sewage will be discharged along with the sludge; and the manual operation of the partition increases the labor burden of the staff.

[0006] In order to solve the above technical problems, the utility model specifically adopts the following technical solutions:

[0007] A sewage sludge separation device comprises a box body, which is connected to a water outlet pipe, partitions are passed through both sides of the box body, and two electric telescopic rods are provided on the box body, which are respectively used to drive the two partitions to move closer to each other; an opening is provided at the bottom of the box body, and a liftable sealing plate is provided in the opening, a folding cylinder is fixed on the top of the sealing plate, a connecting cylinder with filter holes on the surface is fixed on the top of the folding cylinder, and the bottom end of the connecting cylinder is connected to a vertical pipe located on the inner side of the folding cylinder and passing through the sealing plate; a hydraulic rod for driving the vertical pipe to be lifted and lowered is provided at the bottom of the box body, and an automatic telescopic rod for driving the sealing plate and the hydraulic rod to be lifted and lowered synchronously is provided on the box body; a screw rod located below the partition is rotatably connected in the box body, a scraper is threadedly connected to the screw rod, and a motor for driving the screw rod is provided on the box body.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] When a certain amount of sludge is accumulated at the bottom of the box, the two electric telescopic rods are started to make the two partitions move closer to each other. When the opposite sides of the two partitions are in contact, the separation of sewage and sludge in the box is completed; then the vertical pipe is opened to allow the sewage below the partition to enter the connecting cylinder through the filter holes on the connecting cylinder, and the sewage can be discharged through the vertical pipe and collected. At the same time, the hydraulic rod can be started to drive the vertical pipe to move downward, and the vertical pipe drives the connecting cylinder to move downward to compress the folding pipe. After the connecting cylinder moves downward, the sewage above the sludge can continue to enter the connecting cylinder through the filter holes, and then the sewage is discharged through the vertical pipe, thereby further completing the separation of sludge and sewage. When sewage is no longer discharged from the vertical pipe, close the vertical pipe, then start the automatic telescopic rod to drive the sealing plate and the hydraulic rod to move downward synchronously, so that the top of the connecting tube is flush with the bottom surface of the box body, and then start the motor to drive the screw rod to rotate, and the scraper moves in the box body, pushing the sludge in the box body toward the opening at the bottom of the box body, so that the sludge is discharged out of the box body; the utility model can effectively separate the sludge and sewage, avoiding the situation that when the sludge is discharged, part of the sewage will be discharged with the sludge, preventing the impact of untreated sewage on the environment after discharge, and there is no need for staff to manually complete the separation of sludge and sewage, thereby reducing the labor burden of staff.
