Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a sludge sedimentation device. Background Art

[0002] In today's urban and industrial wastewater treatment sectors, effective sludge sedimentation and separation are crucial for achieving water resource reuse and environmental protection. Traditional sewage treatment processes often rely on physical methods such as gravity settling tanks or mechanical pressing to achieve sludge sedimentation and separation, with sludge settling devices playing a central role in this process. However, with increasing environmental protection requirements and increased demand for treatment capacity, traditional settling devices face numerous challenges in terms of treatment efficiency, energy consumption control, and post-treatment sludge quality, necessitating the urgent need for more efficient, energy-saving, and environmentally friendly technical solutions.

[0003] Sewage treatment is the process of purifying sewage to ensure it meets the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. According to the source of sewage, sewage treatment is generally divided into industrial sewage treatment and domestic sewage treatment. After the sewage is settled in the sedimentation tank in the existing technology, the sludge accumulated on the bottom wall of the sedimentation tank needs to be manually cleaned and removed by the staff. This increases the labor intensity of the staff and makes the workers easily fatigued during the sludge cleaning process, thereby reducing the efficiency of the sedimentation tank sludge cleaning. At the same time, the use of manual cleaning operations will undoubtedly reduce the cleaning quality of the sedimentation tank and affect the subsequent operations of the sedimentation tank. In addition, most existing sludge settling technologies will settle some larger impurities together with the sludge to the bottom, causing great inconvenience in subsequent sewage cleaning.

[0004] For example, a sludge sedimentation device for sewage treatment with patent application number CN202220645777.3 discloses "a sedimentation tank, a discharge trough body is provided at the bottom of the sedimentation tank, a discharge hole is provided on the left side of the discharge trough body, a control valve is provided on the left side of the discharge hole, a flip plate is hinged on the inner bottom wall of the sedimentation tank, a lifting assembly is provided on the top of the sedimentation tank, a time-controlled switch is provided on the outer side of the lifting assembly, an annular guide rail is provided on the inner side of the sedimentation tank, and an annular guide groove is provided on the top of the annular guide rail. The sludge sedimentation device for sewage treatment drives the cleaning assembly along the sedimentation tank by driving the moving assembly The inner wall of the sedimentation tank is scraped to prevent sludge from sticking to the inner wall of the sedimentation tank. The time-controlled switch is used to regularly start the lifting assembly to lift the flip plate to the left, so that the sludge slides into the discharge trough body, and the control valve is opened to discharge the sludge from the discharge trough body through the discharge hole and the control valve to prevent the sludge from settling for too long and becoming difficult to discharge. Although the above structure can achieve the sedimentation of sludge in sewage, the sewage contains a large amount of larger impurities, etc.; mixing with the sludge will cause unnecessary trouble in the subsequent cleaning process. For example, when a mud pump is used to clean the sludge, the larger impurities will clog the mud pump and even cause damage to the mud pump. At the same time, the above device needs to be operated frequently to scrape the sludge from the bottom of the sedimentation tank when the sludge is settled. The sludge sedimentation and cleaning is relatively time-consuming and labor-intensive.

[0005] In order to solve the above problems, we provide a sludge settling device that can settle the sludge in sewage and separate the sludge from larger impurities. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a sludge sedimentation device.

[0007] The purpose of the utility model is achieved as follows: a sludge sedimentation device, comprising a box body, wherein partition plate 1 and partition plate 2 are provided in the box body, partition plate 1 is located on the left side of partition plate 2, and partition plate 1 and partition plate 2 divide the box body from left to right into a sedimentation area, a separation area, and an impurity collection area; the lower ends of partition plate 1 and partition plate 2 are not in contact with the bottom of the box body; an inclined plate 1 is provided at the bottom of the separation area and the impurity collection area, and the inclined plate 1 is inclined toward the left bottom; a water inlet pipe is provided on the upper part of the box body at the rear side of the separation area, and a drainage pipe is provided on the upper part of the box body at the front side of the separation area.

[0008] Furthermore, inclined plates 2 are symmetrically distributed on the front and rear sides of the bottom of the sedimentation zone.

[0009] Furthermore, the inclined plates 2 are inclined toward the middle bottom of the settlement area.

[0010] Furthermore, a filter plate is provided between the partition plate 1 and the partition plate 2; the left side of the filter plate is connected to the partition plate 1, and the right side of the filter plate is located below the partition plate 2.

[0011] Furthermore, the filter plate is inclined toward the lower right side.

[0012] The sludge that has settled on the sludge filter screen is filtered out through the filter screen, and the sludge that has settled on the sludge screen is filtered out through the filter screen. When the impurities in the placement frame need to be cleaned, the baffle can be moved downward by rotating the threaded rod so that its bottom fits the filter plate to prevent the impurities from falling onto the placement plate when the placement frame is taken out; then the placement frame can be taken out by the handle to clean the impurities in the placement frame. After cleaning, the placement frame is placed back on the placement plate, and the baffle is reset; the above structure can achieve the effect of sewage sedimentation without affecting the cleaning of the placement frame. The sludge can be filtered through the filter mesh on the front side to prevent a large amount of sludge from being discharged through the drain pipe and affecting the sludge sedimentation effect in the sewage. The present application can add some substances that help sewage sedimentation in the box as needed to increase the sedimentation effect, without technical limitations.

[0013] Beneficial effects: The present application can achieve the sedimentation of sludge in sewage. At the same time, the filter plate can separate larger impurities from the sludge, avoiding damage to the equipment during subsequent sludge cleaning; at the same time, it does not affect the overall sludge sedimentation effect when cleaning impurities; the provision of inclined plate 1 and inclined plate 2 can achieve the goal of guiding the sludge into the middle of the sedimentation area to facilitate subsequent sludge excretion.

[0021] Inclined plates 18 are symmetrically distributed on both sides of the bottom of the sedimentation zone. Inclined plates 18 are angled toward the center bottom of the sedimentation zone. A filter plate 13 is positioned between partitions 1 and 6. The left side of the filter plate 13 is connected to partition 1 and 4, while the right side is located below partition 2. The filter plate 13 is tilted downward and to the right. A support rack is attached to the right side of the filter plate 13, which is connected to the inside of the tank 1.
