[0002] Sludge treatment occupies an important position in the field of environmental protection. Among them, solid-liquid separation is a core link. The sludge sedimentation tank is widely used as a natural sedimentation method. However, how to effectively remove heavy solid particles such as sand is still a technical challenge.

[0003] According to a highly efficient sludge sedimentation tank disclosed in Chinese Patent Publication No. CN212491920U, it includes a sludge sedimentation tank with an opening at the top. A sludge collection box is detachably installed and connected to the bottom of the sludge sedimentation tank. A flipping mechanism is provided on the bottom wall of the sludge sedimentation tank, which can reduce the accumulation of sludge at the bottom of the sedimentation tank and affect the sedimentation effect of the sedimentation tank. Finally, the sludge in the sludge collection box is poured out, which conveniently and quickly realizes the sedimentation and cleaning requirements of the sludge.

[0004] Although this patent can discharge the internal sludge through the setting of the flipping mechanism, there are still certain deficiencies in the actual use process. This patent sets up more auxiliary equipment to help discharge the bottom sludge to ensure the sedimentation effect of the sedimentation tank. Its cost is relatively high, and setting too many electronic drive devices inside the sedimentation tank also requires a great deal of manpower, time, and cost during maintenance, making this solution unable to be widely promoted and used. In response to this, this application provides a sand separation and discharge device for a sludge sedimentation tank to solve the above problems. Summary of the Utility Model

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0030] Please refer to Figures 1 to 3 , the present application provides a technical solution: a sand separation and discharge device for a sludge sedimentation tank, including a sedimentation tank main body 1, a water inlet pipe 2 is fixed on the top of the sedimentation tank main body 1, a sewage discharge pipe 301 is fixed on the bottom of the sedimentation tank main body 1, a sewage pump 302 is fixedly installed on the outer side of the sewage discharge pipe 301, a sand discharge pipe 303 is fixed on the right side of the sedimentation tank main body 1, and a sand-water separation component 500 is installed inside the sedimentation tank main body 1; through the coordinated use of the sewage discharge pipe 301, the sewage pump 302, the sand discharge pipe 303 and the sand-water separation component 500 inside the sedimentation tank main body 1, it is possible to effectively prevent sand from entering the sewage system through a simple structural layout, and facilitate the discharge of sand. At the same time, when the sand accumulates to a certain amount, it can be automatically discharged to realize the timely discharge of sand, thus saving the trouble of manual cleaning. At the same time, different aperture blocking structures can be replaced to adapt to the sedimentation and sewage discharge of different sewage, improving the adaptability and practicability of the overall structure, so that the sand separation and discharge device for this sludge sedimentation tank has a very wide space for popularization.

[0031] It should be noted that an electric valve 401 is fixedly installed on the outer side of the sand discharge pipe 303, and a sand-water filter 402 is fixedly installed on the outer side of the sand discharge pipe 303. The electric valve 401 is located on the side of the outer side of the sand discharge pipe 303 close to the sedimentation tank main body 1, and the sand-water filter 402 is located on the side of the electric valve 401 away from the sedimentation tank main body 1, so that the inside of the sand discharge pipe 303 can be controlled to open through the electric valve 401, and then further separated and filtered through the sand-water filter 402. Among them, the sand-water filter 402 is an integrated device for the separation and lifting of organic sand in sewage, which can separate particles with a particle size ≥ 0.2 mm, and has a high separation efficiency. The device adopts a shaftless screw and no water bearings, and has the characteristics of light weight, compact structure, reliable operation, and convenient installation. It is an ideal sand-water separation device. The sand-water filter 402 is provided with a water inlet end, a sand discharge output end and a water discharge output end. The water discharge output end of the sand-water filter 402 is fixedly connected to the bottom of the sewage discharge pipe 301 through a pipeline, so that the water filtered and separated by the sand-water filter 402 can enter the inside of the sewage discharge pipe 301 for unified transportation, saving water resources, and it is a publicly known technology, so it will not be described in detail.

[0032] In this embodiment, the sand-water separation component 500 is a structure for separating and discharging sediment and water through simple structural cooperation.

[0033] As Figure 1 , Figure 2 and Figure 3 shown, the sand-water separation component 500 includes a sediment sensor 501 fixedly installed inside the sedimentation tank main body 1, a water inlet hopper 502 fixed to the top of the sewage discharge pipe 301, a connecting ring 503 sleeved and abutted against the outside of the water inlet hopper 502, a filter box 504 fixed to the top of the connecting ring 503, a support plate 505 fixed inside the filter box 504, and a plurality of bolts 506 passing through the outside of the connecting ring 503.

[0034] It should be noted that the sediment sensor 501 is an ultrasonic sensor, which can use the reflection of ultrasonic waves to judge the amount of sediment accumulation, and then can facilitate the control of the electric valve 401 to achieve quantitative discharge. The water inlet hopper 502 is in a horn shape and has an open top, so that water can enter normally.

[0035] At the same time, the filter box 504 is in a conical shape and has an open bottom. The inside of the filter box 504 is communicated with the inside of the water inlet hopper 502. Uniformly distributed sediment filter holes are provided on the outside of the filter box 504. The aperture of the sediment filter holes is not greater than 1.5 mm, which can play a role in filtering and blocking sediment. And because the outer surface is an inclined plane, sediment is not easy to accumulate, so that the filtering work can be carried out normally for a long time. The aperture of the sediment filter holes can be opened according to actual needs, so as to prepare filter boxes 504 with different apertures for use.

[0036] In addition, the support plate 505 is in a circular ring shape, and the bottom of the support plate 505 abuts against the top of the water inlet hopper 502, so that the filter box 504 can be supported on the outside top of the water inlet hopper 502 through the support plate 505, which is convenient for the normal progress of the installation work. A plurality of internal thread grooves are provided on the outside of the water inlet hopper 502, and the internal thread grooves can be threadedly connected with the corresponding bolts 506, so that the connecting ring 503 can be fixed on the outside of the water inlet hopper 502 through the threaded connection and cooperation between the bolts 506 and the corresponding internal thread grooves.

[0037] The working principle of the above embodiment is:

[0038] During the sludge sedimentation process, the mixed sewage enters the interior of the sedimentation tank main body 1 through the water inlet pipe 2. Under the action of gravity, the sediment settles on the inner bottom wall of the sedimentation tank main body 1. Under the separation and filtration action of the filtration box 504, the liquid sewage enters the interior of the water inlet hopper 502 after being filtered by the filtration box 504 and is then discharged through the sewage discharge pipe 301. When the sedimentation sensor 501 monitors that there is a large amount of sediment accumulated at the bottom, the electric valve 401 is started, so that the interior of the sand discharge pipe 303 is opened, and the sewage in the sedimentation tank main body 1 will carry the sediment and be discharged through the sand discharge pipe 303. Under the action of the sand-water filter 402, the sand and water can be further separated, reducing the consumption of water resources and conforming to the concept of green environmental protection.

[0039] Compared with the prior art, for the sand separation and discharge device used in this sludge sedimentation tank, through the coordinated use of the sewage discharge pipe 301, sewage pump 302, sand discharge pipe 303 and sand-water separation component 500 inside the sedimentation tank main body 1, it can effectively prevent sand from entering the sewage discharge system through a simple structural layout and facilitate the discharge of sand. At the same time, when the sand accumulates to a certain amount, it can be automatically discharged to achieve the timely discharge of sand, thus saving the trouble of manual cleaning. At the same time, different aperture blocking structures can be replaced to adapt to the sedimentation and sewage discharge of different sewage, improving the adaptability and practicability of the overall structure. Therefore, the sand separation and discharge device used in this sludge sedimentation tank has a very wide space for popularization, solving the disadvantages that the existing high-efficiency sludge sedimentation tank requires a lot of equipment and structures to cooperate during actual use, resulting in high use costs and being not conducive to extensive popularization and use.

[0040] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The provision of the power supply belongs to the common knowledge in the field. The main controller can be a conventional known device such as a computer for control, which can be realized by simple programming by those skilled in the art, and all are existing publicly disclosed electrical connection technologies and will not be elaborated in the text.
