Description

Technical Field

[0001] The utility model relates to the technical field of inclined plate sedimentation towers, in particular to an inclined plate sedimentation tower. Background Art

[0002] Inclined plate sedimentation tower is a water treatment structure that uses the gravity sedimentation of particles or flocs to remove suspended solids in water. The plane form of the inclined plate sedimentation tower is usually rectangular or circular. According to the direction of water flow in the inclined plate sedimentation tower, it can be divided into three types: horizontal flow, vertical flow and radial flow. It is widely used in water supply and sewage treatment processes. Sometimes it is used as a separate water treatment structure with good raw water quality, and its effluent quality can meet the design requirements.

[0003] A shallow sedimentation tank is located between each pair of parallel inclined plates in an inclined plate sedimentation tower. This allows the treated water (or wastewater) and settled sludge to move and separate within the shallow sedimentation layer. Based on the forces driving these interactions, separation methods can be categorized as co-current flow, counter-current flow, and lateral flow. Inclined plate sedimentation towers utilize the principle of "shallow sedimentation" to shorten the particle settling distance, thereby reducing sedimentation time and increasing the sedimentation area of ​​the sedimentation tank, thereby improving treatment efficiency.

[0004] Chinese Patent No. CN201610171958.6 discloses an inclined plate sedimentation device and a sedimentation tank constructed using the device. The device comprises a plurality of parallel inclined plate sedimentation units, each comprising a mud slide, an inlet water baffle, and an outlet water baffle. The inlet and outlet water baffles extend normally from the mud slide surface and, together with the mud slide surface, form a mud slide channel. The mud discharge port of the mud slide channel is located within or at the bottom of a sedimentation channel on the side of the device. The gaps between the inlet and outlet water baffles and adjacent mud slides form a water passage. A mud baffle extending vertically downward from the lower end of the mud slide at the mud discharge port in the sedimentation channel is provided.

[0005] The inclined plate sedimentation unit of the inclined plate sedimentation device disclosed above includes a mud slide, an inlet water baffle and an outlet water baffle. When the inclined plate sedimentation device is composed of more than two inclined plate sedimentation units, the two or more inclined plate sedimentation units are fixedly connected, which makes the overall inclined plate sedimentation device larger in size and heavier in weight, making it difficult to quickly install the inclined plate sedimentation device into the inclined plate sedimentation tower, and it is also difficult to adjust or replace one or more inclined plate sedimentation units.

DETAILED DESCRIPTION

[0028] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0029] like Figures 1-9As shown, an inclined plate sedimentation tower includes a bracket 1 and a sedimentation tower body 2 installed on the bracket 1; the sedimentation tower body 2 includes a sedimentation tank 3 and a filter tank 4 connected to the top of the sedimentation tank 3, and the filter tank 4 is provided with a plurality of filter inclined plates 5 arranged along the length direction of the filter tank 4; the filter tank 4 is provided with a hanging part 6 for hanging the corresponding filter inclined plates 5, and the filter tank 4 is provided with at least one support rod 43 for passing through the plurality of filter inclined plates 5.

[0030] The sedimentation tower body 2 is suspended under the action of the bracket 1, and the filter tank 4 and the sedimentation tank 3 are distributed up and down. The filter inclined plate 5 is used to filter the liquid in the filter tank 4 and precipitate various impurities under the action of the liquid's own gravity. The impurities are precipitated into the sedimentation tank 3.

[0031] The hanging part 6 is used to connect the top of the filter inclined plate 5. Under the action of the hanging part 6, the filter inclined plate 5 is suspended in the filter tank 4 to support the horizontal position of the filter inclined plate 5. At the same time, under the action of the support rod 43 and the filter inclined plate 5, the height support of all the filter inclined plates 5 is achieved.

[0032] The number of the support rods 43 is set according to actual needs, and the support rods 43 are all in a horizontal state. Under the support of the support rods 43, all the filter inclined plates 5 are at the same horizontal height.

[0033] A liquid inlet 41 and an anti-overflow port 42 are respectively formed at both ends of the filter pool 4. The anti-overflow port 42 is located above the liquid inlet 41, and the liquid is taken in by the pipeline. When the water level in the filter pool 4 reaches a certain height, when the water level overflows the anti-overflow port 42, the liquid in the filter pool 4 will be discharged from the anti-overflow port 42, thereby preventing the liquid in the filter pool 4 from overflowing from the top of the filter pool 4.

[0034] An inclined structure 44 is formed at one end of the filter tank 4, which is inclined inward from top to bottom. The end of the support rod 43 is in contact with the inclined structure 44, and the anti-overflow port 42 is formed at the top of the inclined structure 44. Under the action of the inclined structure 44, the end of the support rod 43 can be supported to prevent the end of the support rod 43 from sinking, thereby ensuring that the support rod 43 is always in a horizontal state. At the same time, the inclined structure 44 can also play a certain diversion role for the liquid in the filter tank 4.

[0035] A serrated plate 9 is provided in the filter pool 4 along the length direction of the sedimentation tower. The serrated plate 9 is located above several filter inclined plates 5. The serrated plate 9 is used to increase the contact area between the filter pool 4 and the liquid. Therefore, under the action of the serrated plate 9, the fluidity of the water flow in the filter pool 4 is reduced, thereby meeting the filtering requirements of the filter inclined plates 5 for the liquid.

[0036] A lifting ring 51 is formed on the top of the filter inclined plate 5 along the length direction of the filter inclined plate 5. The lifting ring 51 is hung on the hanging piece 6. The lifting ring 51 facilitates the operator to grab the filter inclined plate 5, and the hanging ring 51 is hung on the hanging piece 6 to realize the overhead setting of the filter inclined plate 5.

[0037] The hanging member 6 includes a connecting rod 61 and a clamping rod 62 , wherein a clamping groove 63 for clamping with the hanging ring 51 is formed in the middle of the clamping rod 62 . The clamping groove 63 is arranged along the length direction of the clamping rod 62 .

[0038] The connecting rod 61 is fixedly connected to the inner wall of the filter tank 4 by welding or bolt connection, and the clamping rod 62 is arranged along the length direction of the connecting rod 61. The connecting rod 61 and the clamping rod 62 are both in an inclined setting state, and the inclination angles of the connecting rod 61 and the clamping rod 62 are consistent with the required inclination angle of the filter inclined plate 5.

[0039] A bending section 52 is formed on the lifting ring 51, and the bending section 52 is arranged in abutment at the connection between the connecting rod 61 and the clamping rod 62. Since the connecting rod 61 and the clamping rod 62 are arranged to be tilted downward, the bending section 52 abuts against the end of the clamping rod 62 under the action of gravity, thereby achieving the limitation and support of the position of the lifting ring 51.

[0040] The bent section 52 is bent along the inclination direction of the filter inclined plate 5 to prevent the bent section 52 from being separated from the hanging member 6 under the action of gravity.

[0041] Several cover plates 7 for sealing the top opening of the filter tank 4 are placed on the top of the filter tank 4. A handle 71 for grabbing the cover plate 7 is installed in the middle of the cover plate 7, and a support seat 45 connected to the bracket 1 and an abutment seat 46 for increasing the contact area of ​​the cover plate 7 are formed on the top of the filter tank 4.

[0042] The number of cover plates 7 is set according to actual needs. The handle 71 facilitates grabbing of the cover plates 7 to open or close the top of the filter tank 4. The support seat 45 and the abutment seat 46 are used to achieve stable support for the cover plates 7.

[0043] A maintenance platform 8 connected to the bracket 1 is provided on one side of the sedimentation tower body 2 . The maintenance platform 8 includes a patterned steel plate 81 and a guardrail frame 82 for supporting the patterned steel plate 81 .

[0044] During actual use, the operator can stand on the maintenance platform 8 and observe the situation in the filter tank 4 by holding the cover plate 7. At the same time, when installing the filter inclined plate 5, the operator can also stand on the maintenance platform 8 and gradually install each filter inclined plate 5 as the support rod 43 moves. After the filtering effect of the filter inclined plate 5 is saturated, the operator can disassemble and replace each filter inclined plate 5.

[0045] The above description of the disclosed embodiments will enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
