Description

Technical Field

[0001] This utility model relates to the field of water treatment, and more specifically, it relates to a sedimentation tank. Background Technology

[0002] Sedimentation tanks are a common facility used in water treatment. Harmful substances in wastewater with added chemicals will precipitate out in solid form. In addition, some wastewater itself contains solid particles, so solid-liquid separation is necessary. Sedimentation tanks are a good way to allow solid particles to settle naturally at the bottom of the tank, while the liquid on top flows into the next treatment stage. However, existing sedimentation tanks generally only slow down the flow rate to allow solids to settle slowly. A certain path length is required to ensure the settling rate of solids. When the path is short, some solids will be carried into the next stage by the liquid before they can settle. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sedimentation tank.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sedimentation tank, including a tank body, wherein an inlet channel and an outlet channel are provided on the tank body, a partition is vertically arranged inside the tank body, the partition divides the inner cavity of the tank body into an inlet cavity and an outlet cavity, a filter plate is horizontally arranged in the outlet cavity, the filter plate divides the outlet cavity into an upper cavity and a lower cavity, the top end of the inlet cavity is connected to the inlet channel, the bottom end of the inlet cavity is connected to the lower cavity through a connection port, and the top end of the upper cavity is connected to the outlet channel.

[0005] The present invention is further configured such that the filter plate is detachably connected to the pool body.

[0006] The present invention is further configured such that the cross-sectional area of ​​the upper cavity is larger than that of the lower cavity, and the filter plate is slidably connected in the upper cavity along the vertical direction.

[0007] The present invention is further configured such that: a pull rod is fixedly connected to the top surface of the filter plate, and a gap is formed between the pull rod and the filter plate.

[0008] The present invention is further configured such that: a drain outlet is provided on the side wall of the lower cavity away from the water inlet cavity, and a gate is covered on the side of the drain outlet away from the lower cavity, and the gate is slidably connected to the pool body.

[0009] The present invention is further configured such that the flow area of ​​the connection port gradually increases along the direction of water flow.

[0010] The present invention is further configured such that the bottom surface of the inner cavity of the pool gradually decreases along the direction of water flow.

[0011] In summary, this utility model has the following beneficial effects: by changing the straight flow channel structure along the horizontal direction to a U-shaped flow channel structure, the space occupied by the sedimentation tank is saved, while ensuring the effect of solid sedimentation. The inclined bottom of the tank body causes the solids to accumulate towards the direction of the sewage outlet, avoiding blockage of the connection port and ensuring sewage discharge efficiency.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A sedimentation tank, such as Figure 1 , Figure 2 As shown, the system includes a pool body 1, with an inlet channel 2 and an outlet channel 3. A partition 4 is vertically installed inside the pool body 1, dividing the inner cavity of the pool body 1 into an inlet chamber 5 and an outlet chamber. A filter plate 6 is horizontally installed inside the outlet chamber, dividing the outlet chamber into an upper chamber 7 and a lower chamber 8. The top of the inlet chamber 5 is connected to the inlet channel 2, and the bottom of the inlet chamber 5 is connected to the lower chamber 8 through a connection port 9. The top of the upper chamber 7 is connected to the outlet channel 3.

[0017] Specifically, the inlet channel 2 and the outlet channel 3 are both located at the top of the same side of the tank body 1. The baffle 4 is located between the inlet channel 2 and the outlet channel 3, so that the inlet channel 2 is only connected to the inlet chamber 5 and the outlet channel 3 is only connected to the outlet chamber. Sewage flows into the inlet chamber 5 from the inlet channel 2 and falls down along the inlet chamber 5, and then flows into the lower chamber 8 through the connection port 9. As more sewage flows in, the water level in the lower chamber 8 gradually rises, and solids are retained at the bottom of the lower chamber 8. At the same time, the filter screen prevents solids from passing through, preventing solids from leaving the sedimentation tank with the water flow. The liquid gradually fills the upper chamber 7 and finally flows out from the outlet channel 3. By changing the straight flow channel structure along the horizontal direction to a U-shaped flow channel structure, the space occupied by the sedimentation tank is saved, while ensuring the effect of solid sedimentation.

[0018] like Figure 1 , Figure 2As shown, the filter plate 6 is detachably connected to the pool body 1. The cross-sectional area of ​​the upper cavity 7 is larger than that of the lower cavity 8. The filter plate 6 is slidably connected to the upper cavity 7 in the vertical direction. A pull rod 10 is fixedly connected to the top surface of the filter plate 6. A gap is formed between the pull rod 10 and the filter plate 6. Specifically, the bottom cross-sectional area of ​​the upper cavity 7 is larger than the opening area at the top of the lower cavity 8. Therefore, when the filter plate 6 slides down the upper cavity 7 to the bottom of the upper cavity 7, it will stop. When it is necessary to remove the filter plate 6 for cleaning, the filter plate 6 can be removed by pulling the pull rod 10 at the top of the filter plate 6 upward with a hook or other tool. The width at the bottom of the filter plate 6 is smaller than the width at the top of the filter plate 6. During the lifting process, the filter plate 6 can be slightly deflected to avoid jamming.

[0019] like Figure 1 , Figure 2 As shown, a drain outlet 11 is provided on the side wall of the lower cavity 8 away from the water inlet cavity 5. A gate 12 is covered on the side of the drain outlet 11 away from the lower cavity 8. The gate 12 is slidably connected to the pool body 1. The flow area of ​​the connection port 9 gradually increases along the water flow direction, and the bottom surface of the inner cavity of the pool body 1 gradually decreases along the water flow direction. Specifically, the inclined bottom surface of the pool body 1 causes solids to accumulate towards the drain outlet 11, avoiding blockage of the connection port 9 and ensuring sewage discharge efficiency. The top wall of the connection port 9 is horizontal, making the connection port 9 flared along the water flow direction, further preventing blockage of the connection port 9. A sliding groove is provided on the outer side wall of the pool body 1 where the gate 12 is located. The gate 12 slides vertically in the sliding groove. When it is necessary to clean the solid accumulation in the lower cavity 8, the liquid in the top of the water inlet cavity 5 and the upper cavity 7 is drained, and the gate 12 is pulled upward. Most of the accumulation flows out from the drain outlet 11. Then, the inside of the pool body 1 is cleaned by scraping and rinsing to achieve the cleaning of the solid accumulation.
