Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water purification plant canal transformation, in particular to a horizontal flow sedimentation tank. Background Technique
[0002] The theoretical basis of the conventional horizontal flow sedimentation tank is that under the action of gravity, when the raw water to be treated flows through the sedimentation area of the sedimentation tank, the suspended particles in the water gradually settle along the way, so that the suspended particles are separated from the water. And the value representing the treatment capacity (or sedimentation capacity, also known as the water production per unit area) of the sedimentation tank is equal to the settling velocity of the smallest particles that can be completely removed from the most unfavorable point entering the sedimentation tank.
[0003] In the existing horizontal flow sedimentation tank, due to the critical settling velocity of the particles, the expected critical settling velocity cannot be effectively achieved. Increasing the area of the sedimentation tank can effectively solve the problem of insufficient critical settling velocity, but this will require an increase in the floor area of the sedimentation tank, and most water treatment plants do not have such conditions. Therefore, it is necessary to transform the current common effluent mode of the horizontal flow sedimentation tank on the premise of controlling the dosage of chemicals (reducing the treatment cost) without increasing the floor area of the sedimentation tank.
[0004] Therefore, we propose a horizontal flow sedimentation tank to effectively solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a horizontal flow sedimentation tank, which solves the problem that in the existing horizontal flow sedimentation tank, due to the critical settling velocity of the particles, the expected critical settling velocity cannot be effectively achieved.

The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0021] The utility model provides a horizontal flow sedimentation tank, which comprises a tank body 101 and a flow-accumulating sedimentation component. The flow-accumulating sedimentation component includes a water inlet chamber 104, a sedimentation chamber 105, a placement chamber 106, a water outlet chamber 107, a drainage chamber 108, a water inlet pipe 102, a water outlet pipe 103, a water collection plate 109, a water collection trough 110, a flow-blocking trough 111 and a drainage plate 112. Through the foregoing solution, the problem that the existing horizontal flow sedimentation tank cannot effectively reach the expected critical settling velocity due to the critical settling velocity of particles is solved. It can be understood that in the foregoing solution, when the raw water is normally subjected to sedimentation and quality removal operations, the raw water is transmitted into the tank body 101 from the water inlet. The raw water will first enter the water inlet chamber 104 and flow from the water inlet chamber 104 into the sedimentation chamber 105. The water collection plate 109 in the placement chamber 106 will cooperate with the water collection trough 110 and the flow-blocking trough 111 to effectively delay the duration of the raw water in the sedimentation chamber 105, facilitating the precipitation of impurities in the raw water. After the raw water is settled, it will enter the water outlet chamber 107, and the sedimented raw water will be transmitted from the water outlet chamber 107 to the drainage chamber 108. The drainage plate 112 in the drainage chamber 108 will effectively guide the sedimented raw water to drain from the water outlet pipe 103. Thus, the problem that the existing horizontal flow sedimentation tank cannot effectively reach the expected critical settling velocity due to the critical settling velocity of particles is effectively solved.
[0022] For this specific embodiment, the water inlet chamber 104 is fixedly connected to the tank body 101 and is located on one side inside the tank body 101. The sedimentation chamber 105 is fixedly connected to the tank body 101 and is located inside the tank body 101, and the sedimentation chamber 105 is arranged on one side of the water inlet chamber 104. The placement chamber 106 is fixedly connected to the tank body 101 and is located inside the tank body 101, and the placement chamber 106 is arranged on the side of the sedimentation chamber 105 away from the water inlet chamber 104. The water outlet chamber 107 is fixedly connected to the tank body 101 and is located inside the tank body 101, and the water outlet chamber 107 is arranged on the side of the placement chamber 106 away from the sedimentation chamber 105. The drainage chamber 108 is fixedly connected to the tank body 101 and is located inside the tank body 101, and the drainage chamber 108 is arranged on the side of the water outlet chamber 107 away from the placement chamber 106. The tank body 101 is the main place for sedimentation and quality removal operations, and the water inlet chamber 104 will be the channel for transmitting the raw water to the sedimentation chamber 105 for sedimentation operations, and the placement chamber 106 is the space for placing the water collection plate 109.
[0023] Among them, the water inlet pipe 102 is detachably connected to the pool body 101 and is located on one side of the pool body 101 close to the water inlet. The water outlet pipe 103 is detachably connected to the pool body 101 and is located on one side of the pool body 101 close to the drainage cavity 108. And the water outlet pipe 103 is arranged perpendicular to the water inlet pipe 102. The water inlet pipe 102 and the water outlet pipe 103 are auxiliary components for transmitting and discharging raw water into and out of the pool body 101.
[0024] Secondly, the water collecting plate 109 is detachably connected to the pool body 101 and is located inside the pool body 101. And the water collecting plate 109 is arranged below the inside of the placement cavity 106. The water collecting groove 110 is fixedly connected to the water collecting plate 109 and is located above the inside of the water collecting plate 109. The water collecting plate 109 is a functional component that cooperates with the water collecting groove 110 and the flow blocking groove 111 to perform a flow blocking and deceleration operation on the raw water in the sedimentation cavity 105, effectively delaying the transmission speed of the raw water.
[0025] At the same time, the flow blocking groove 111 is fixedly connected to the water collecting plate 109 and is located inside the water collecting plate 109. And the flow blocking plate is arranged below the water collecting groove 110. The drainage plate 112 is arranged below the inside of the drainage cavity 108. And the opening of the drainage plate 112 is arranged on one side of the water outlet pipe 103 close to the drainage cavity 108.
[0026] When using the present utility model to normally perform sedimentation and quality removal operations on raw water, the raw water will be transmitted into the pool body 101 from the water inlet. The raw water will first enter the water inlet cavity 104 and flow from the water inlet cavity 104 into the sedimentation cavity 105. And the water collecting plate 109 in the placement cavity 106 will cooperate with the water collecting groove 110 and the flow blocking groove 111 to effectively delay the duration of the raw water in the sedimentation cavity 105, facilitating the precipitation of impurities in the raw water. After the raw water is settled, it will enter the water outlet cavity 107, and the water outlet cavity 107 will transmit the settled raw water to the drainage cavity 108. And the drainage plate 112 in the drainage cavity 108 will effectively guide the settled raw water to drain from the water outlet pipe 103. Thus, the problem that the existing horizontal flow sedimentation tank cannot effectively reach the expected critical settling velocity due to the critical settling velocity of particles is effectively solved.

[0030] For this specific embodiment, the filter plate 201 is detachably connected to the water inlet pipe 102 and is located inside the water inlet pipe 102. The sponge block 202 is detachably connected to the water outlet pipe 103 and is located inside the water outlet pipe 103. The filter plate 201 will effectively intercept impurities visible to the naked eye outside the tank body 101, while the sponge block 202 will effectively prevent the problem of incomplete sedimentation of raw water.
