[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely used in various fields and can achieve the purpose of recycling and saving water resources. Since sewage contains a large amount of solid impurities, solid-liquid separation equipment is needed.

[0003] In the Chinese utility model patent with the publication number of CN221432307U, a solid-liquid separation device for sewage treatment is disclosed. By setting a three-stage separation structure, the gradual separation, removal and centralized collection and treatment of impurities and foreign matters in sewage are realized, so that solid and liquid are fully separated;

[0004] Through retrieval and combined with the actual sewage treatment work experience, there are still some defects and deficiencies in the above solid-liquid separation device in actual application: when cleaning and discharging solid impurities in the above device, the first-stage filter screen and the second-stage filter screen need to be taken out. During this process, the continuous treatment of sewage needs to be stopped, which affects the treatment speed and efficiency of the device and cannot realize continuous sewage treatment. Therefore, it is urgent to improve the existing sewage treatment solid-liquid separation equipment and provide a sewage treatment solid-liquid rapid separation device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a sewage treatment solid-liquid rapid separation device with reasonable design, simple structure, which can operate continuously, has a faster treatment speed and higher efficiency, aiming at solving the problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A sewage treatment solid-liquid rapid separation device includes a treatment tank. A lifting component is arranged on the inner side of the middle part of the treatment tank. A separation component is installed below the treatment tank. A motor is fixedly installed on the left side wall at the top of the treatment tank. The output end of the motor is fixedly connected with a diamond-shaped rod. A third conical gear is fixedly sleeved on the outer side of the top of the diamond-shaped rod. A connecting sleeve is clamped and slidably sleeved on the outer side of the bottom of the diamond-shaped rod. A support rod is sleeved on the shaft end of the outer side of the top of the connecting sleeve. The support rod is fixed on the left side wall of the separation component. A fourth conical gear is fixedly sleeved on the outer side of the bottom of the connecting sleeve.

[0008] As a preferred embodiment, the lifting assembly includes a horizontal shaft, a first bevel gear, and a connecting rod. The horizontal shaft is mounted on the inner side of the middle part of the processing box through bearings. First bevel gears are fixedly connected to both the left and right ends of the horizontal shaft. Connecting rods are hinged to the sides of the two first bevel gears facing away from the processing box.

[0009] As a preferred embodiment, the hinge point of the connecting rod and the first bevel gear is located at the outer edge position of the first bevel gear away from its center. The left first bevel gear is meshed and connected with the third bevel gear.

[0010] As a preferred embodiment, the separation assembly includes a separation pipe, a screw conveyor, a second bevel gear, a drainage groove, a filter screen, and a water receiving hopper. The separation pipe is located below the processing box. The screw conveyor is mounted on the inner side of the separation pipe through bearings. A second bevel gear is fixedly connected to the left end of the screw conveyor. A drainage groove is opened at the bottom left end of the separation pipe. A filter screen is fixedly connected to the inner side of the drainage groove. A water receiving hopper is fixedly connected to the outer wall of the bottom left end of the separation pipe.

[0011] As a preferred embodiment, the second bevel gear is meshed and connected with the fourth bevel gear, and the screw conveyor and the horizontal shaft are linked with each other.

[0012] As a preferred embodiment, the left water inlet of the separation pipe is slidably and sealingly sleeved outside the lower left water outlet of the processing box. The bottom ends of the two connecting rods are respectively hinged to the left and right ends of the separation pipe. The right end of the support rod is fixedly connected to the separation pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In the solution of the present utility model:

[0015] When performing solid-liquid separation, the motor can be started to control the synchronous rotation of the diamond-shaped rod and the third bevel gear. At this time, by using the first bevel gear meshed with the third bevel gear, the horizontal shaft and the two first bevel gears can be controlled to rotate synchronously and rapidly. Since the hinge point of the connecting rod and the first bevel gear is located at the outer edge position of the first bevel gear away from its center, when the first bevel gear rotates, the left and right connecting rods can be used to pull the separation pipe to perform high-frequency small-amplitude reciprocating lifting, which can achieve a vibrating effect, accelerate the speed of sewage passing through the filter screen, and make the solid-liquid separation faster;

[0016] Since the diamond-shaped rod is engaged and slidably connected with the connecting sleeve, during the vibration of the separation pipe, the diamond-shaped rod can still drive the connecting sleeve and the fourth bevel gear to rotate stably. Thus, the second bevel gear meshed with the fourth bevel gear can drive the screw conveyor to rotate stably. The rotating screw conveyor can push and convey the solid impurities intercepted above the filter screen to the right, which can not only prevent the filter screen from being blocked, but also facilitate the discharge of the solid impurities without stopping the sewage treatment, avoiding affecting the speed of sewage solid-liquid separation.

On the left side wall of the top of the processing box 1, a motor 4 is fixedly installed. The output end of the motor 4 is fixedly connected to a diamond rod 5. On the outer side of the top of the diamond rod 5, a third conical tooth 6 is fixedly sleeved. On the outer side of the bottom of the diamond rod 5, a connecting sleeve 7 is snap-fitted and slidably sleeved. On the outer side of the top of the connecting sleeve 7, a support rod 8 is sleeved at the shaft end. The support rod 8 is fixed on the left side wall of the separation component 3. On the outer side of the bottom of the connecting sleeve 7, a fourth conical tooth 9 is fixedly sleeved.

[0028] On the basis of the above structure, the lifting component 2 includes a horizontal shaft 21, a first bevel gear 22 and a connecting rod 23. The horizontal shaft 21 is installed on the inner side of the middle part of the processing box 1 through bearings. First bevel gears 22 are fixedly connected to both the left and right ends of the horizontal shaft 21, and connecting rods 23 are hinged to the sides of the two first bevel gears 22 facing away from the processing box 1.

[0029] On the basis of the above structure, the hinge point of the connecting rod 23 and the first bevel gear 22 is located at the outer edge position of the first bevel gear 22 away from its center of the circle, and the left first bevel gear 22 is meshed and connected with the third bevel gear 6.

[0030] In this embodiment, when controlling the diamond-shaped rod 5 to drive the third bevel gear 6 to rotate, the first bevel gear 22 and the horizontal shaft 21 meshed with the third bevel gear 6 can be controlled to rotate stably and quickly. The left and right connecting rods 23 can be used to pull the separation component 3 to perform small-amplitude reciprocating lifting at a high frequency, which can produce a vibrating effect, accelerate the speed of sewage passing through the filter screen 35, and make the solid-liquid separation faster.

[0031] On the basis of the above structure, the separation component 3 includes a separation pipe 31, an auger 32, a second bevel gear 33, a drainage groove 34, a filter screen 35 and a water receiving hopper 36. The separation pipe 31 is located below the processing box 1. The auger 32 is installed on the inner side of the separation pipe 31 through bearings. A second bevel gear 33 is fixedly connected to the left end of the auger 32. A drainage groove 34 is opened at the bottom left end of the separation pipe 31, a filter screen 35 is fixedly connected to the inner side of the drainage groove 34, and a water receiving hopper 36 is fixedly connected to the outer wall of the bottom left end of the separation pipe 31.

[0032] On the basis of the above structure, the second bevel gear 33 is meshed and connected with the fourth bevel gear 9, and the auger 32 and the horizontal shaft 21 are interlocked.

[0033] On the basis of the above structure, the left water inlet of the separation pipe 31 is slidably and sealingly sleeved on the outside of the lower left water outlet of the processing box 1. The bottom ends of the two connecting rods 23 are respectively hinged to the left and right ends of the separation pipe 31, and the right end of the support rod 8 is fixedly connected to the separation pipe 31.

[0034] In this embodiment, the diamond-shaped rod 5 can also drive the connecting sleeve 7 and the fourth bevel gear 9 to rotate synchronously, so as to control the second bevel gear 33 meshed with the fourth bevel gear 9 to drive the auger 32 to rotate. The rotating auger 32 can push the solid impurities intercepted above the filter screen 35 to the right for conveying, which can not only prevent the filter screen 35 from being blocked, but also facilitate the discharge of the solid impurities without stopping the sewage treatment.

[0035] The working principle of the present utility model is as follows:

[0036] In use, first add the sewage to be treated into the treatment tank 1. The sewage flows into the separation pipe 31 through the treatment tank 1 and is filtered through the filter screen 35. The sewage can be discharged through the drainage groove 34 and the water receiving hopper 36, and the solid impurities can be intercepted above the filter screen 35. During this process, the motor 4 can be started to control the diamond-shaped rod 5 to drive the third conical tooth 6 to rotate rapidly, so as to drive the first conical tooth 22 and the horizontal shaft 21 engaged with the third conical tooth 6 to rotate rapidly. Since the hinge point of the connecting rod 23 and the first conical tooth 22 is located at the outer edge of the first conical tooth 22 away from its center, when the first conical tooth 22 rotates rapidly, the left and right connecting rods 23 can be used to pull the separation pipe 31 to perform small-amplitude reciprocating lifting at a high frequency, which can achieve a vibrating effect, accelerate the speed of the sewage passing through the filter screen 35, make the solid-liquid separation faster, and the left end water inlet sliding seal of the separation pipe 31 is sleeved outside the lower left water outlet of the treatment tank 1, which can prevent sewage leakage;

[0037] The diamond-shaped rod 5 can also drive the connecting sleeve 7 and the fourth conical tooth 9 that are snap-fitted and sleeved on the outside of its bottom to rotate rapidly, so that the auger 32 can be driven to rotate stably through the second conical tooth 33 engaged with the fourth conical tooth 9. The rotating auger 32 can push the solid impurities intercepted above the filter screen 35 to the right for conveying, which can not only prevent the filter screen 35 from being blocked, but also facilitate the discharge of the solid impurities without stopping the sewage treatment, avoiding affecting the speed of solid-liquid separation of the sewage.

[0038] The above is only the preferred specific embodiment of the present invention, and is not used to limit the protection scope of the present invention; any equivalent changes, modifications, substitutions and variations made by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments shall be within the protection scope determined by the claims.
