Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a settling tank for wastewater treatment. Background Technology

[0002] With the rapid development of industrialization, water pollution has become increasingly serious, especially muddy water. Muddy water is difficult to purify in one go and requires step-by-step purification. The first step is to let it settle. Settling tanks or settling containers are mostly used for this purpose. However, when using settling containers, only mud and sand can be settled, and mud-water separation cannot be achieved quickly and effectively. Furthermore, the filtration and purification systems of some existing settling containers are relatively simple and cannot fully remove impurities and harmful substances from the wastewater. As a result, the cleanliness of the treated water is not high and cannot meet the increasingly stringent discharge standards and reuse requirements.

[0003] Meanwhile, during the wastewater settling process, the sludge that settles at the bottom of the device tends to accumulate and harden. Existing devices usually lack an effective sludge cleaning mechanism, making it difficult to discharge the sludge in a timely manner. This not only occupies the effective space of the device, but may also have an adverse effect on the subsequent wastewater treatment effect.

[0004] According to the description in the patent website of a wastewater treatment settling tank (authorization announcement number: CN208471712U), the wastewater treatment settling tank includes "tank body, treatment pipe" etc., to achieve settling.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This wastewater treatment settling tank utilizes the tank body and treatment pipes to achieve settling. During use, the wastewater is filtered through activated carbon before entering the storage chamber. Although activated carbon is used for filtration, sludge still mixes with the wastewater and settles at the bottom of the tank. This settling tank cannot clean this sludge, and the sludge that settles at the bottom of the tank tends to accumulate and harden. Furthermore, removing and adding activated carbon is complicated, and the filtration structure is simple and ineffective. Therefore, this settling tank needs to be improved. Utility Model Content

[0007] The purpose of this invention is to provide a settling tank for sewage treatment to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a settling tank for sewage treatment, comprising a base, a settling mechanism on the top of the base, and a sealing mechanism on the top of the settling mechanism;

[0009] The settling mechanism includes a settling tank body, which is fixedly connected to the top of a base. A fixing frame is fixedly connected to the inner side of the settling tank body, and a processing box is fixedly connected to the inner side of the fixing frame. A fixing seat is fixedly connected to the bottom of the inner side of the processing box. A filter cylinder is slidably connected to the periphery of the fixing seat. An activated carbon filter element is slidably connected to the inner side of the filter cylinder. A protective cover is threadedly connected to the top of the filter cylinder. A connecting shaft is provided on the top of the protective cover. A filter frame is fixedly connected to the top of the connecting shaft. The filter frame is slidably connected to the inner side of the processing box. A servo motor is fixedly connected to the bottom of the settling tank body. A rotating shaft is fixedly connected to the top of the servo motor. The rotating shaft is rotatably connected to the inside of the settling tank body. A scraper is fixedly connected to the top of the rotating shaft. The scraper is located inside the settling tank body.

[0010] Preferably, a sludge discharge pipe is fixedly connected to the bottom left side of the settling tank body, and a drain pipe is fixedly connected to the middle right side of the settling tank body. The top and bottom of the inner cover are in contact with the top of the activated carbon filter element and the bottom of the connecting shaft, respectively. The bottom of the scraper is in contact with the inner bottom of the settling tank body, so that the sludge at the inner bottom of the settling tank body can be cleaned by the scraper.

[0011] Preferably, the outer periphery and bottom of the treatment box do not contact the inner side and bottom of the settling tank. The inside of the fixing base and the bottom of the treatment box are respectively provided with through holes, and the through holes are circular and correspond to each other to facilitate the flow of sewage.

[0012] Preferably, the filter cylinder has water inlet holes inside and at its inner bottom, and both water inlet holes are circular. The water inlet hole at the bottom of the inner side of the filter cylinder is located at the top of the through hole inside the fixed base, so that the filtered wastewater can enter the through hole inside the fixed base through the water inlet hole.

[0013] Preferably, the fixing base, filter cylinder, activated carbon filter element and protective cover are provided in six sets and symmetrically distributed inside the treatment box, which facilitates further improvement of the sewage treatment effect.

[0014] Preferably, the sealing mechanism includes a load-bearing frame, which is fixedly connected to the rear side of the settling tank body. A hydraulic cylinder is fixedly connected to the top of the load-bearing frame, and a movable frame is fixedly connected to the bottom of the hydraulic cylinder. A connecting arm is fixedly connected to the front side of the movable frame, and a sealing cover is fixedly connected to the inner side of the connecting arm. The sealing cover is located on the top of the settling tank body, and a water inlet is fixedly connected to the top of the sealing cover.

[0015] Preferably, the bottom of the sealing cap is in contact with the top of the settling tank body, and the movable frame is slidably connected inside the load-bearing frame, so as to ensure the sealing of the top of the settling tank body through the sealing cap.

[0016] Compared with the prior art, the present invention provides a settling tank for sewage treatment, which has the following beneficial effects:

[0017] 1. This wastewater treatment settling tank, through its settling mechanism, allows for the slidable connection of an activated carbon filter element inside the filter cylinder when wastewater needs to be settling. Multiple filter components are symmetrically distributed inside the treatment tank, forming a multi-layer filtration system. Wastewater first undergoes preliminary filtration through the filter frame and filter cylinder, and then further adsorbs impurities and harmful substances through the activated carbon filter element, greatly improving the wastewater purification effect and resulting in cleaner water. A protective cover is threaded onto the top of the filter cylinder. When the activated carbon filter element reaches its service life or its filtration effect decreases, the protective cover can be easily unscrewed for convenient removal and replacement, eliminating the need for complex disassembly. Corresponding through holes and inlet holes on the treatment tank, mounting base, and filter cylinder form a reasonable water flow channel, allowing wastewater to enter the filter cylinder from the top of the treatment tank in an orderly manner. After filtration, it enters the bottom of the settling tank for settling and sedimentation. A servo motor drives the rotating shaft and scraper, which promptly scrapes away the sludge settled at the bottom of the settling tank during the wastewater settling process, preventing sludge accumulation and compaction.

[0018] 2. This wastewater treatment settling tank, through its sealing mechanism, hydraulic cylinder-driven moving frame, connecting arm, and sealing cover design, enables rapid sealing and opening of the settling tank body. When wastewater treatment is required, the hydraulic cylinder pushes the sealing cover to tightly fit the top of the settling tank body, preventing the emission of wastewater odors and the falling of debris. At the same time, the water inlet on the top of the sealing cover facilitates wastewater injection. The operation is simple and flexible, improving the efficiency of wastewater treatment and facilitating the subsequent cleaning or replacement of equipment such as filter frames and activated carbon filter elements inside the settling tank body.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-6 This utility model provides a technical solution: a settling tank for sewage treatment, including a base 1, a settling mechanism 2 on the top of the base 1, and a sealing mechanism 3 on the top of the settling mechanism 2;

[0032] The settling mechanism 2 includes a settling tank body 21, which is fixedly connected to the top of the base 1. A fixing frame 24 is fixedly connected to the inside of the settling tank body 21. A processing box 25 is fixedly connected to the inside of the fixing frame 24. A fixing seat 27 is fixedly connected to the bottom of the processing box 25. A filter cylinder 28 is slidably connected to the outside of the fixing seat 27.

A connecting shaft 291 is provided on the top of the protective cover 292. A filter frame 26 is fixedly connected to the top of the connecting shaft 291. The filter frame 26 is slidably connected to the inside of the processing box 25. A servo motor 293 is fixedly connected to the bottom of the settling tank body 21. A rotating shaft 294 is fixedly connected to the top of the servo motor 293. The rotating shaft 294 is rotatably connected to the inside of the settling tank body 21. A scraper 295 is fixedly connected to the top of the rotating shaft 294. The scraper 295 is located inside the settling tank body 21.

[0033] A sludge discharge pipe 22 is fixedly connected to the bottom left side of the settling tank body 21, and a drain pipe 23 is fixedly connected to the middle right side of the settling tank body 21. The top and bottom of the inner part of the protective cover 292 are in contact with the top of the activated carbon filter element 29 and the bottom of the connecting shaft 291, respectively. The bottom of the scraper 295 is in contact with the bottom of the inner side of the settling tank body 21, so that the sludge at the bottom of the inner side of the settling tank body 21 can be cleaned by the scraper 295.

[0034] The outer periphery and bottom of the treatment box 25 do not contact the inner side and bottom of the settling tank body 21. The inside of the fixing base 27 and the bottom of the treatment box 25 are respectively provided with through holes, and the through holes are circular and correspond to each other, so as to facilitate the flow of sewage.

[0035] The filter cartridge 28 has water inlet holes inside and at the bottom of its inner side. The water inlet holes are all circular. The water inlet hole at the bottom of the inner side of the filter cartridge 28 is located at the top of the through hole inside the fixed base 27, which facilitates the filtered sewage to enter the through hole inside the fixed base 27 through the water inlet hole. There are six sets of fixed base 27, filter cartridge 28, activated carbon filter element 29 and protective cover 292, which are symmetrically distributed inside the treatment box 25 to further improve the sewage treatment effect.

[0036] Example 2

[0037] Please see Figure 1-6 Furthermore, based on Embodiment 1, the sealing mechanism 3 includes a load-bearing frame 31, which is fixedly connected to the rear side of the static bucket body 21. A hydraulic cylinder 32 is fixedly connected to the top of the load-bearing frame 31, and a movable frame 33 is fixedly connected to the bottom of the hydraulic cylinder 32. A connecting arm 34 is fixedly connected to the front side of the movable frame 33, and a sealing cover 36 is fixedly connected to the inner side of the connecting arm 34. The sealing cover 36 is located on the top of the static bucket body 21, and a water inlet 35 is fixedly connected to the top of the sealing cover 36.

[0038] The bottom of the sealing cap 36 is in contact with the top of the settling tank body 21, and the movable frame 33 is slidably connected inside the load-bearing frame 31, so that the sealing cap 36 can ensure the sealing of the top of the settling tank body 21.

[0039] In actual operation, when this device is used and sewage needs to be settled, firstly, the activated carbon filter element 29 is placed into the filter cylinder 28, and the top of the filter cylinder 28 is sealed by the protective cover 292. At the same time, the top of the inner part of the protective cover 292 is in contact with the top of the activated carbon filter element 29 to ensure its stability. Then, the filter cylinder 28 is slidably connected to the outside of the fixed base 27, and the bottom is in contact with the bottom of the inner side of the treatment box 25. At the same time, the filter frame 26 is slidably connected to the inner side of the treatment box 25, and the bottom of the connecting shaft 291 is in contact with the top of the protective cover 292. After installation, it can be connected to the drain pipe 23 through the external collection pipe, and the collection device is placed at the bottom of the sludge discharge pipe 22.

[0040] The design of the hydraulic cylinder 32 driving the moving frame 33, connecting arm 34 and sealing cover 36 can realize the rapid sealing and opening of the settling tank body 21. When sewage treatment operation is required, the hydraulic cylinder 32 pushes the sealing cover 36 to fit tightly against the top of the settling tank body 21 to prevent sewage odor from escaping and debris from falling in. At the same time, the water inlet 35 at the top of the sealing cover 36 can transport sewage into the settling tank body 21. When sewage enters the settling tank body 21 through the water inlet 35, the sewage first enters the inside of the filter frame 26 for preliminary work. After filtration, the sewage enters the inside of the treatment tank 25, where it is further adsorbed by the filter cylinder 28 and activated carbon filter element 29, which greatly improves the sewage purification effect and makes the treated water cleaner.

[0041] After filtration, the wastewater enters the through hole inside the fixed base 27 through the water inlet hole at the bottom of the filter cylinder 28, and enters the bottom of the settling tank body 21 through the through hole at the bottom of the treatment box 25 for settling. Since the outer periphery and bottom of the treatment box 25 do not contact the inner side and bottom of the settling tank body 21, the wastewater after treatment and settling can be discharged through the drain pipe 23 on the right side of the settling tank body 21.

[0042] When sludge needs to be treated, the servo motor 293 drives the rotating shaft 294 and the scraper 295 to scrape the sludge settled at the bottom of the settling tank body 21 in a timely manner during the sludge cleaning process, preventing the sludge from accumulating and hardening, and allowing the sludge to be discharged through the sludge discharge pipe 22. At the same time, the hydraulic cylinder 32 drives the sealing cover 36 away from the top of the settling tank body 21, so that the filter frame 26 can be cleaned. At the same time, the protective cover 292 can be opened to replace the activated carbon filter element 29, and the inside of the treatment box 25 can be cleaned to ensure the treatment effect of the sewage.
