Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation equipment technology, specifically to a rapid solid-liquid separator. Background Technology

[0002] In production processes involving water washing, the resulting water often contains a large number of solid particles, forming a suspension. This suspension must undergo sedimentation and filtration before it can be reused. However, conventional sedimentation and filtration processes are time-consuming.

[0003] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0004] The purpose of this invention is to provide a rapid solid-liquid separator.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A solid-liquid rapid separator includes a settling tank, which is cylindrical.

[0007] A high-pressure water inlet pipe is connected tangentially to the periphery of the settling tank;

[0008] A water outlet pipe is connected to the middle of the bottom of the settling tank. The top of the water outlet pipe extends into the inner cavity of the settling tank, and a filter is provided at the pipe opening at the top of the water outlet pipe to filter the liquid flowing into the pipe opening.

[0009] The bottom of the settling tank is connected to several settling cylinders, which are arranged in a ring array around the outlet pipe. Each settling cylinder is in the shape of an inverted cone and its bottom end is connected to a sedimentation pipe.

[0010] Preferably, the opening at the top of the water outlet pipe is lower than the opening of the high-pressure water inlet pipe.

[0011] Preferably, the top of the filter is connected to the top of the settling tank, and the bottom is connected to the wall of the outlet pipe extending into the settling tank.

[0012] Preferably, the filter is a filter screen arranged in an inverted cone shape.

[0013] Preferably, the bottom center of the settling tank protrudes into the cavity to form a boss, which is conical in shape, and the top of the water outlet pipe passes through the boss and is sealed to the boss.

[0014] Preferably, a damping plate is arranged on the inner wall of the settling cylinder near the outlet pipe, and the damping plate is inclined downward.

[0015] Preferably, a gate valve is provided in the middle of the sedimentation tube and at the bottom of the tube.

[0016] Preferably, the high-pressure water inlet pipe is connected to a high-pressure water pump.

[0017] The working principle and advantages of this utility model are as follows:

[0018] This invention features a high-pressure water inlet pipe tangentially connected to the outer wall of a cylindrical settling tank. A filter is installed on the outer side of the water outlet inside the settling tank. Multiple inverted conical settling cylinders are evenly arranged at the bottom of the tank. When the high-pressure water flows into the settling tank, it generates a large centrifugal force and moves downward under the action of gravity, achieving diversion and entering each settling cylinder. In the settling cylinder, an even greater centrifugal force is generated, and the particulate matter is further accumulated and precipitated. The centrifuged water is filtered by the filter and then overflows from the water outlet pipe, achieving solid-liquid separation. The entire separator has a simple structure, separates quickly, and can immediately clean and reuse more than 90% of the suspension with water. Attached Figure Description

[0031] See appendix Figure 1-3 A solid-liquid rapid separator includes a settling tank 1, which is cylindrical.

[0032] A high-pressure water inlet pipe 2 is connected to the circumference of the settling tank 1 along the tangential direction, and the high-pressure water inlet pipe 2 is connected to a high-pressure water pump 3.

[0033] A water outlet pipe 4 is connected to the middle of the bottom of the settling tank 1. The top end of the water outlet pipe 4 extends into the inner cavity of the settling tank 1. The opening of the top end of the water outlet pipe 4 is lower than the opening of the high-pressure water inlet pipe 2 to facilitate drainage.

[0034] A filter 5 is provided at the top of the outlet pipe 4 to filter the liquid flowing into the pipe. The filter 5 is a filter screen with an inverted cone shape. The top of the filter 5 is connected to the top of the settling tank 1, and the bottom is connected to the wall of the outlet pipe 4 that extends into the settling tank 1.

[0035] The bottom of the settling tank 1 is connected to several settling cylinders 6. Each settling cylinder 6 is arranged in a ring array with the outlet pipe 4 as the center. Each settling cylinder 6 is inverted conical and its bottom end is connected to a sedimentation pipe 7. A first gate valve 10 is provided in the middle of the sedimentation pipe 7, and a second gate valve 11 is provided at the bottom of the sedimentation pipe 7.

[0036] The settling cylinder 6 has a damping plate 8 arranged on its inner wall near the outlet pipe 4. The damping plate 8 is inclined downward.

[0037] The bottom center of the settling tank 1 protrudes into the cavity to form a boss 9, which is conical in shape. The top end of the water outlet pipe 4 passes through the boss 9 and is sealed to the boss 9.

[0038] The above-mentioned separator is used to perform solid-liquid separation of wastewater:

[0039] Before the separation operation, the second gate valve 11 on the sedimentation tube 7 is in the closed state, and the first gate valve 10 is in the open state;

[0040] Separation operation: High-pressure water pump 3 pumps sewage into the settling tank 1 at high speed along the tangential direction through high-pressure water inlet pipe 2. The water flows rapidly along the inner wall of the settling tank 1 and the outer space of the filter 5, generating a large centrifugal force, which causes the particles in the sewage to quickly gather on the inner wall of the settling tank 1 and move downward under the action of gravity. Then, the particles enter each inverted conical settling cylinder 6 with the water, which can generate a greater centrifugal force to further accumulate on the inner wall of the settling cylinder 6 and settle in the sedimentation tube 7 under the action of gravity.

[0041] In this process, due to the presence of filter 5, particulate matter is blocked on the outside of filter 5 before entering the settling cylinder 6, and clean water can reach the inside of filter 5. The particulate matter blocked by filter 5 can gradually settle and slide down through the conical outer wall of the boss 9. The damping plate 8 inside the settling cylinder 6 can further block some of the particulate matter in the water from moving upward with the water. When the water level inside filter 5 rises to the outlet of water pipe 4, it is discharged from the outlet of water pipe 4.

[0042] As the amount of particulate matter precipitated in each sedimentation tube 7 increases, in order to avoid affecting the separation efficiency and quality, the sedimentation tube 7 needs to be cleaned regularly: close the first gate valve 10 and open the second gate valve 11. The particulate matter located below the first gate valve 10 can be discharged from the sedimentation tube 7. After the discharge is complete, close the second gate valve 11 and open the first gate valve 10. With this design, the sedimentation tank 1 does not need to stop the separation work during sewage discharge and can work continuously to purify sewage.

[0043] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
