Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a slag-liquid separation device for treating wastewater. Background Technique

[0002] The treatment process of sewage often involves basic knowledge in aspects such as physics, chemistry, physical chemistry, and biochemistry, and uses many corresponding facilities, equipment, and automatic control devices. Moreover, many physical, chemical, and biological testing methods are also used in analysis and monitoring. The wastewater generated in industrial production contains a large amount of waste residue, which greatly increases the difficulty of sewage treatment.

[0003] The existing wastewater treatment equipment cannot separate the slag in the wastewater, and the separated waste residue often still contains a large amount of wastewater and is not treated cleanly enough; and after the wastewater is filtered, due to the filter screen being inside the device, it is rather troublesome to clean. Therefore, a slag-liquid separation device for treating wastewater is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a slag-liquid separation device for treating wastewater to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A slag-liquid separation device for treating wastewater includes a first outer shell. The top end of the first outer shell is fixedly connected with a feed pipe. The bottom end of the first outer shell is spirally connected with a first sealing cover. The bottom end of the first sealing cover is provided with a first drain pipe. The bottom end of the first sealing cover is fixedly connected with a motor. The output end of the motor is fixedly connected with a first rotating shaft. The top end of the first rotating shaft is fixedly connected with a limiting block. There is a second rotating shaft outside the limiting block at the top end of the first rotating shaft. The top end of the second rotating shaft is fixedly connected with a fixing block. The outside of the fixing block is fixedly connected with a fixing plate. The outside of the fixing plate is fixedly connected with a fixing ring. The top end of the fixing ring is fixedly connected with a baffle. An outlet is provided on the outside of the first outer shell. The inside of the first outer shell is fixedly connected with a first engaging ring below the outlet. A third filter screen is provided at the bottom end of the first engaging ring. A second engaging ring is provided at the bottom end of the third filter screen. Fixing holes are provided at the top ends of the first engaging ring, the third filter screen, and the second engaging ring. Bolts are spirally connected inside the fixing holes. A first filter screen is fixedly connected between the fixing ring and the fixing plate.

[0007] Preferably, a second outer shell is fixedly connected to the outside of the first outer shell. A hydraulic rod is fixedly connected inside the second outer shell. The bottom end of the hydraulic rod is fixedly connected to a pressure plate. A slag discharge port is formed on the outside of the second outer shell. A second sealing cover is spirally connected to the inside of the slag discharge port. A second drain pipe is formed at the bottom end of the second outer shell. A support ring is fixedly connected inside the second outer shell below the pressure plate. A second filter screen is fixedly connected inside the support ring.

[0008] Preferably, the outer edge of the pressure plate is in close fit with the inner wall of the second outer shell.

[0009] Preferably, a fixing groove is formed at the bottom end of the second rotating shaft. A limiting block is snap-connected inside the fixing groove.

[0010] Preferably, the baffle is in a semi-circular ring shape and is fixedly arranged at a high position on the right side of the top of the fixed ring.

[0011] Preferably, the second engaging ring is slidably connected to the inside of the first outer shell.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, through components such as a motor, a first rotating shaft, a limiting block, a second rotating shaft, a fixing groove, a fixing block, a fixing plate, a first filter screen, a second rotating shaft, a baffle, a fixed ring, a discharge port, a hydraulic rod, a pressure plate, a support ring, and a second filter screen, the motor drives the first rotating shaft to rotate. Under the action of the limiting block and the fixing groove, the first rotating shaft drives the second rotating shaft to rotate. The second rotating shaft drives the fixing block, the fixing plate, the first filter screen, the fixed ring, and the baffle to rotate. Under the action of the baffle, the direction of the waste residue in the wastewater is ensured. Under the rotating action, it is ensured that the waste residue goes to the lower part of the fixed ring. The filtered wastewater continues to be filtered through the first filter screen. The filtered waste residue will be thrown into the discharge port under the action of centrifugal force and enter the second outer shell through the discharge port. The waste residue is squeezed by the hydraulic rod and the pressure plate, and the waste residue will remain on the second filter screen. The wastewater is discharged from the second drain pipe through the second filter screen, completing the separation of sewage and slag, thus solving the problem that the existing wastewater treatment equipment cannot separate the slag in the wastewater, and the separated waste residue often still contains a large amount of wastewater and the treatment is not clean enough;

[0014] 2. In the present utility model, through components such as the first outer shell, the first sealing cover, the first rotating shaft, the limiting block, the fixing groove, the second rotating shaft, the first engaging ring, the third filter screen, the second engaging ring, the fixing hole and the bolt, when it is necessary to clean the third filter screen, the first sealing cover is rotated to separate the first sealing cover from the first outer shell, and the limiting block of the first rotating shaft is also withdrawn from the fixing groove of the second rotating shaft. Then, the bolt is rotated to separate the bolt from the fixing hole. Without the fixation of the bolt, the second engaging ring and the third filter screen can be removed, which is convenient for cleaning. Thus, the problem that it is rather troublesome to clean due to the filter screen being inside the device after wastewater filtration is solved. BRIEF DESCRIPTION OF THE DRAWINGS
