Description

Technical Field

[0001] This utility model relates to the field of water supply system technology, specifically to a high-efficiency sedimentation tank for urban and rural water supply. Background Technology

[0002] In urban and rural water supply systems, sedimentation tanks are crucial facilities for removing impurities from water and ensuring water quality. Traditional sedimentation tanks often face problems during operation, such as insufficient treatment of influent impurities, low sedimentation efficiency, and inadequate sludge discharge, making it difficult to meet the growing demands for water quality and supply efficiency in urban and rural areas. Against this backdrop, high-efficiency sedimentation tanks for urban and rural water supply have emerged, aiming to solve the above problems, optimize the sedimentation process, and achieve efficient and stable operation of urban and rural water supply systems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a high-efficiency sedimentation tank for urban and rural water supply. It can efficiently purify water, ensure water quality, operate stably with low maintenance costs, and achieve convenient sewage discharge and smooth circulation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a mixing inlet tank 1, a sedimentation outlet tank 2, an inlet 3, an outlet 4, a sewage pump 5, a mixer 6, a flocculation zone 7, a water collection zone 8, a sedimentation zone 9, a grid plate 11, and an inclined plate 12; the mixing inlet tank 1 and the sedimentation outlet tank 2 are integrally formed, the mixing inlet tank 1 is provided with multiple inlets 3 around its outer perimeter, the sedimentation outlet tank 2 is provided with an outlet 4 on each of its left and right sides, and a sewage pump 5 is provided on each of the front and rear surfaces of the sedimentation outlet tank 2; the mixer 6 is installed in the middle of the mixing inlet tank 1; the uppermost part of the sedimentation outlet tank 2 is the flocculation zone 7, the lowermost part of the sedimentation outlet tank 2 is the sedimentation zone 9, the water collection zone 8 is located between the flocculation zone 7 and the sedimentation zone 9, and the flocculation zone 7, the water collection zone 8, and the sedimentation zone 9 are separated by the grid plate 11; the sedimentation zone 9 is provided with inclined plates 12 connected to the grid plate 11 on its left and right sides.

[0005] Furthermore, the mixing inlet tank 1 is a circular reinforced concrete casting structure, and the sedimentation outlet tank 2 is a square reinforced concrete casting structure. The mixing inlet tank 1 and the sedimentation outlet tank 2 are integrally cast with reinforced concrete.

[0006] Furthermore, an acrylic dust cover 101 is installed above the mixing water inlet tank 1 to prevent impurities other than water from entering the sedimentation tank and ensure the efficient operation of the sedimentation tank.

[0007] Furthermore, the grid plate 11 can be selected with different grid sizes according to the actual working conditions to settle and filter impurities in the sedimentation tank.

[0008] Furthermore, the inclined plate 12 is installed at an angle of 30°, 45°, or 60°. The installation angle of the inclined plate 12 can be adjusted according to different working conditions to facilitate the discharge of debris from the sedimentation zone by the sewage pump 5.

[0009] The working principle of this utility model is as follows: mixing and stirring: raw water flows into the pool through multiple inlets 3 around the mixing inlet pool 1. The mixer 6 installed in the middle of the mixing inlet pool 1 is then started to strongly stir the raw water, so as to promote the full mixing of raw water and flocculant, creating conditions for subsequent flocculation and sedimentation.

[0010] Flocculation and sedimentation: The stirred and mixed raw water enters the flocculation zone 7 of the sedimentation tank 2, where impurities in the water flocculate into larger particles. Subsequently, the flocculated water passes through the grid plate 11 and enters the sedimentation zone 9. Inclined plates 12 installed on both sides of the sedimentation zone 9 utilize the principle of shallow sedimentation to increase the sedimentation area, accelerate particle settling, and improve sedimentation efficiency. Different installation angles of the inclined plates 12 (30°, 45°, or 60°) can be adjusted according to actual working conditions to adapt to different sedimentation requirements.

[0011] Water collection and discharge: The purified water, after sedimentation treatment, passes through the grid plate 11 into the water collection area 8, and is then discharged through the outlets 4 on the left and right sides of the sedimentation outlet tank 2, thus realizing the collection and utilization of purified water.

[0012] Impurity removal: Impurities settled at the bottom of sedimentation zone 9 are pumped out of the sedimentation tank by the suction of sewage pump 5, thus completing the removal of impurities. In addition, the dust cover 101 above the mixing inlet tank 1 can prevent external impurities from entering, ensuring that the sedimentation process is not disturbed and maintaining the efficient and stable operation of the sedimentation tank.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: efficient purification and protection of water quality: the agitator in the mixing tank promotes the full integration of raw water and flocculant. The flocculation zone, sedimentation zone and inclined plate work together to purify the raw water layer by layer, effectively removing impurities in the water, greatly improving the purification effect and ensuring the safety of water quality in urban and rural water supply.

[0014] Flexible adaptation and improved efficiency: The grid plate can be selected with different grid sizes according to the actual working conditions, and the installation angle of the inclined plate can be flexibly adjusted between 30°, 45° or 60°, so as to adapt to diverse water quality and working conditions, improve sedimentation efficiency, and meet the water supply needs of different urban and rural scenarios.

[0015] Stable operation and reduced maintenance: The sedimentation tank adopts a reinforced concrete structure with a mixed inlet tank and a sedimentation outlet tank integrated into one piece, making it sturdy and durable. The dust cover above the mixed inlet tank effectively prevents external impurities from entering, reducing internal pollution of the sedimentation tank, lowering the risk of failure due to impurity accumulation, and reducing maintenance frequency and costs.

[0016] Convenient sewage discharge and smooth circulation: Sewage pumps are installed on the front and rear surfaces of the sedimentation tank. Combined with the special design of the inclined plate, they can efficiently discharge impurities from the bottom of the sedimentation zone, avoid the accumulation of impurities affecting the sedimentation effect, ensure the continuous and stable purification work of the sedimentation tank, and achieve a virtuous cycle of the water supply system.

[0022] See Figure 1-3 As shown, the technical solution adopted in this specific embodiment is:

[0023] Example 1: Centralized water supply scenario in rural towns

[0024] A township experienced continuous population growth, and the existing water supply sedimentation tank, due to its low purification efficiency, could not meet the residents' water needs, and the water quality frequently failed to meet standards. After introducing this high-efficiency sedimentation tank for urban and rural water supply, the sedimentation tank operates according to the following parameters:

[0025] Equipment configuration: Select a 5mm grid plate and set the inclined plate installation angle to 45°.

[0026] Operation: During peak daily water usage periods, raw water flows into the mixing tank through multiple inlets. A mixer operates at 200 rpm to ensure thorough mixing of the raw water and flocculant. The mixed water then enters the sedimentation tank, where the flocculation zone promotes the flocculation and sedimentation of impurities, and inclined plates accelerate the sedimentation process. The purified water is collected in the collection area and flows out from the outlet. A sewage pump is activated every 4 hours to remove impurities from the sedimentation zone.

[0027] Implementation results: The water quality has been significantly improved, meeting national drinking water standards. The daily water supply capacity has increased from 1,000 cubic meters to 1,500 cubic meters, effectively meeting the water needs of township residents.

[0028] Example 2: Secondary water supply scenario in urban residential communities

[0029] A residential community in a certain city, located at a higher elevation, requires a secondary water supply. The original sedimentation tank frequently experienced insufficient water supply and turbid water quality during the summer peak water usage period. After adopting this high-efficiency sedimentation tank:

[0030] Equipment configuration: Based on the water quality, select a 3mm mesh plate and adjust the angle of the inclined plate to 60°.

[0031] Operational status: During peak summer water usage, raw water enters the mixing tank, and the mixer speed is increased to 300 rpm to enhance mixing. In the sedimentation tank, the water undergoes rapid purification after flocculation and sedimentation. The sewage pump is intelligently controlled and starts as needed based on the amount of impurities accumulated in the sedimentation zone.

[0032] Results: The water quality for residents in the community is stable and clear. During the summer peak water usage period, the water supply pressure is stable and there have been no further water shortages. Residents' satisfaction with water use has greatly improved.

[0033] Example 3: Rural Irrigation Water Scenarios

[0034] In a rural area where agricultural irrigation is the primary method of water use, the water source contains a high amount of silt and other impurities. Traditional sedimentation tanks have poor sedimentation efficiency, leading to blockages in irrigation pipes. After introducing this high-efficiency sedimentation tank:

[0035] Equipment configuration: Uses 8mm grid plates, with the inclined plate installation angle set to 30°.

[0036] Operation: During irrigation, raw water enters the mixing inlet tank, is thoroughly mixed by the mixer, and then enters the sedimentation outlet tank. The flocculation zone and the sedimentation zone work together to remove impurities such as silt from the water. The sewage pump is started periodically to clean impurities from the sedimentation zone.

[0037] Results: The sediment content in irrigation water has been significantly reduced, the problem of irrigation pipe blockage has been effectively solved, ensuring the smooth progress of farmland irrigation and increasing crop yields.
