Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to a horizontal flow sedimentation tank which is convenient for cleaning sediment. Background Art

[0002] A horizontal flow sedimentation tank consists of three parts: an inlet, an outlet, a water flow part and a sludge hopper. The plane of the tank body is rectangular, and the inlet and outlet are respectively arranged at both ends of the tank. The inlet generally adopts a submerged inlet hole, and water flows into the tank body through the uniformly distributed inlet holes from the inlet channel. A baffle is arranged behind the inlet hole to make the water flow evenly distributed in the cross section of the whole tank width; the outlet mostly adopts an overflow weir to ensure that the clarified water after sedimentation can flow evenly into the outlet channel along the tank width. A scum trough and a baffle are arranged in front of the weir to intercept the floating scum on the water surface. The water flow part is the main body of the tank, and the tank width and depth should ensure that the water flow is evenly distributed along the water passing section of the tank, and slowly and stably flows through according to the designed flow velocity. Due to the slow water flow velocity, the sediment such as sand carried in the water gradually precipitates under the action of gravity. The sediment such as sand generally accumulates in the front half of the tank body.

[0003] In the prior art, such as a horizontal flow sedimentation tank which is convenient for cleaning sediment in Chinese Patent CN 210251347 U, it includes a sedimentation tank body, a plurality of split sludge hoppers are arranged in the sedimentation tank body, a sludge cavity is arranged in the sludge hopper, a one-way valve is arranged at the bottom of the sludge cavity, and lifting rods are symmetrically arranged on the top surface of the sludge hopper. The utility model has the advantages of simple structure, low cost and high effect. The sludge hopper can be conveniently lifted and placed, but the patent still has the following problems.

[0004] In the above patent, although the patent has a simple structure, low cost and high effect, and the sludge hopper can be conveniently lifted and placed, when cleaning the sludge hopper, since the sludge hopper leaves the sedimentation tank body at this time, in order to prevent the sludge from falling to the bottom of the sedimentation tank body, the sewage inlet cannot continue to supply water at this time, reducing the sedimentation efficiency. Content of the Utility Model

[0005] The utility model mainly provides a horizontal flow sedimentation tank which is convenient for cleaning sediment, can conveniently improve the sludge sedimentation efficiency and prevent the sludge from falling to the bottom of the sedimentation tank body.

A clamping groove 15 is opened on the outer wall of the sloping plate 6, two limiting grooves 9 are opened on the inner wall of the tank body 1, a first spring 10 is fixedly installed on the inner wall of each of the two limiting grooves 9, a moving plate 11 is fixedly installed at one end of the first spring 10, a clamping block 12 is fixedly installed at the end of the moving plate 11 away from the first spring 10, a through hole 13 is penetrated through the inner wall of the limiting groove 9, a pulling plate 14 is fixedly installed on the top of the moving plate 11, and the pulling plate 14 is slidably connected to the through hole 13. A water inlet pipe 2 and a water outlet pipe 3 are respectively penetrated and installed on both sides inside the tank body 1.

[0025] As Figure 5 shown, connecting plates 24 are fixedly installed on the tops of a plurality of sludge boxes 5, and fixing plates 4 are fixedly installed on the tops of the connecting plates 24. Workers can drive the sludge boxes 5 to rise by pulling the fixing plates 4 through the connecting plates 24.

[0026] As Figure 4 shown, slots 16 are opened at the bottoms of a plurality of fixing plates 4, fixing grooves 19 are opened on the inner walls of the slots 16, threaded holes 20 are penetrated through the inner walls of the fixing grooves 19, and the outer walls of the inserting plates 17 are fitted with the inner walls of the slots 16 to prevent the fixing plates 4 from shaking.

[0027] As Figure 4 shown, a threaded rod 21 is threadedly connected inside the threaded hole 20, a connecting block 22 is fixedly installed at one end of the threaded rod 21 close to the slot 16, and a handle 23 is fixedly installed at the end of the threaded rod 21 away from the connecting block 22. Workers can drive the connecting block 22 to move by rotating the handle 23 through the threaded rod 21.

[0028] As Figure 4As shown in the figure, a plurality of uniformly distributed insertion plates 17 are fixedly installed at the top of the pool body 1. Connecting grooves 18 are formed through the outer wall of the insertion plates 17. The outer wall of the connecting block 22 fits with the inner wall of the connecting groove 18. When the connecting block 22 enters the connecting groove 18, the fixing plate 4 can be fixed.

[0029] As Figure 5 shown in the figure, U-shaped grooves 26 are formed in the side walls of a plurality of sludge boxes 5. A plurality of uniformly distributed second springs 27 are fixedly installed on the inner wall of the U-shaped grooves 26.

When the clamping groove 15 moves beside the clamping block 12, the staff releases the pull plate 14, and the elastic force of the first spring 10 pushes the clamping block 12 into the clamping groove 15 to fix the inclined plate 6. At this time, the sewage in the water inlet pipe 2 contacts the inclined plate 6 and then falls along the inclined plate 6 into the sludge box 5 on the other side. At this time, the staff can clean the sludge box 5 without sludge entering, improving the sludge sedimentation efficiency. Then the staff pulls the connecting plate 24, and the sludge box 5 rises. When the pressing plate 29 contacts the inclined surface of the inclined plate 6, the pressing plate 29 is squeezed and drives the U-shaped plate 28 into the U-shaped groove 26 until it leaves the pool body 1. When placing the sludge box 5, the staff sleeved the slot 16 on the insertion plate 17, and then the staff rotated the handle 23. The handle 23 drove the threaded rod 21 to rotate, and then the threaded rod 21 moved along the threaded hole 20, so that the connecting block 22 left the fixing groove 19 and entered the connecting groove 18. At this time, the insertion plate 17 was fixed, and then the sludge box 5 was fixed, which was convenient for positioning.
