Description

Technical Field

[0001] The utility model belongs to the field of water treatment, and particularly relates to a sedimentation and separation device. Background Art

[0002] In sewage treatment, a sedimentation and separation device is used to change the water flow direction, so as to change the water flow state, thereby sedimenting and separating the sludge in the water flow. According to different water flow directions, the currently common sedimentation and separation devices are of two types: a sedimentation and separation device with horizontal flow and vertical sludge discharge, and a sedimentation and separation device with upward flow and sludge discharge.

[0003] The structure of the sedimentation and separation device with horizontal flow and vertical sludge discharge includes a frame and multiple inclined plates. The multiple inclined plates are divided into multiple columns and welded on the frame. The two sides of each inclined plate are respectively welded on the frame. The upper and lower adjacent inclined plates enclose a water flow channel. There is a gap between the left and right adjacent columns of inclined plates. During use, the water flow enters each water flow channel horizontally from the side of the device, and the sludge in the water flow precipitates along each inclined plate and vertically falls through the gap between the two columns of inclined plates. The difficulty in manufacturing the sedimentation and separation device with horizontal flow and vertical sludge discharge lies in the large amount of on-site welding work, which is prone to causing artificial installation errors, and inconvenient for factory transportation.

[0004] The structure of the sedimentation and separation device with upward flow and sludge discharge includes a frame and multiple inclined plates. Each inclined plate is a whole large plate. The two sides of each inclined plate are respectively welded on the frame. The upper and lower adjacent inclined plates enclose a water flow channel. During use, the water flow enters each water flow channel upward from the bottom of the device, and the sludge in the water flow precipitates along each inclined plate and slides down. Due to the large size of the inclined plates of the sedimentation and separation device with upward flow and sludge discharge and the high requirement for flatness, this sedimentation and separation device with horizontal flow and vertical sludge discharge also needs to be assembled in the workshop, and it is inconvenient for factory transportation. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a sedimentation and separation device that is convenient for transportation and assembly in view of the deficiencies of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problem is: a sedimentation and separation device, including a frame and multiple inclined plates arranged in parallel. Each of the inclined plates is obliquely arranged inside the frame. Multiple positioning grooves are obliquely arranged on the frame. One side of each inclined plate is spot-welded to the frame, and the other side of each inclined plate is inserted and fixed in several of the positioning grooves.

[0007] The inclined plates of the sedimentation and separation device of the present utility model adopt a mounting method of spot welding and fixing with positioning grooves, which is convenient for assembly. Each component can be transported separately and assembled at the use site after leaving the factory, rather than completing the assembly of the entire sedimentation and separation device before leaving the factory, thereby reducing the transportation difficulty and improving the convenience and efficiency of transportation. By setting the positioning grooves, the angles of the inclined plates can be ensured to be uniform, improving the assembly accuracy of the device.

[0008] Preferably, the frame is a frame structure assembled by multiple vertical plates and multiple horizontal plates. The inner space of the frame is divided into multiple six-sided open square spaces by the multiple vertical plates and the multiple horizontal plates. One column of inclined plates is arranged in each square space. The inclined plates in each square space are arranged at equal intervals from top to bottom. Multiple positioning grooves are arranged at equal intervals from top to bottom on one side of each vertical plate. One side of each inclined plate is spot welded to several vertical plates, and the other side of each inclined plate is inserted and fixed in several positioning grooves. Dividing the inner space of the frame into multiple six-sided open square spaces and arranging one column of inclined plates in each square space is beneficial to further simplify the installation operation of the sedimentation and separation device and realize modular design and installation.

[0009] In an implementation scheme, the horizontal width of each positioning groove on each vertical plate is less than the horizontal width of the vertical plate, so as to form a gap between two adjacent columns of inclined plates on the left and right. Two adjacent inclined plates up and down enclose a water flow channel for horizontal flow. This sedimentation and separation device is a sedimentation and separation device with horizontal flow and vertical sludge discharge. During use, water flows horizontally into each water flow channel for horizontal flow from the side of the device, and the sludge in the water precipitates along each inclined plate and falls vertically through the gap between the two columns of inclined plates.

[0010] In another implementation scheme, the horizontal width of each positioning groove on each vertical plate is equal to the horizontal width of the vertical plate. Two adjacent inclined plates up and down enclose an upward flow water flow sub-channel. The adjacent upward flow water flow sub-channels on the left and right are sequentially connected to form an upward flow water flow channel. The surfaces of the inclined plates at the bottom of each upward flow water flow channel are on the same inclined plane. This sedimentation and separation device is a sedimentation and separation device with upward flow sludge discharge. During use, water flows upward into each upward flow water flow channel from the bottom of the device, and the sludge in the water precipitates along each inclined plate and slides down.

[0011] Compared with the prior art, the utility model has the following advantages: the inclined plates of the sedimentation separation device of the utility model adopt a mounting method of spot welding and fixing with positioning grooves, which is convenient for assembly. The components can be transported separately, and assembled on-site after leaving the factory, rather than completing the assembly of the entire sedimentation separation device before leaving the factory, thereby reducing the transportation difficulty and improving the convenience and efficiency of transportation. By setting the positioning grooves, the angles of the inclined plates can be ensured to be uniform, and the assembly accuracy of the device can be improved. Description of the Drawings

Detailed Description of the Embodiment

[0019] The following further describes the present utility model in detail with reference to the drawings and embodiments.

[0020] The sedimentation separation device of Embodiment 1 is a sedimentation separation device with horizontal flow and vertical sludge discharge, as Figures 1 to 3 shown. The sedimentation separation device includes a frame 1 and multiple inclined plates 2 arranged in parallel. The frame 1 and the multiple inclined plates 2 are both made of stainless steel. Each inclined plate 2 is inclined and arranged inside the frame 1. Multiple positioning grooves 13 are inclinedly arranged on the frame 1. One side of each inclined plate 2 is spot-welded to the frame 1, and the other side of each inclined plate 2 is inserted and fixed in several positioning grooves 13.

[0021] In Example 1, the frame 1 is a frame structure assembled by a plurality of vertical plates 11 and a plurality of horizontal plates 12. The inner space of the frame 1 is divided into a plurality of square spaces 14 with six open sides by the plurality of vertical plates 11 and the plurality of horizontal plates 12. A row of inclined plates 2 is arranged in each square space 14. The inclined plates 2 in each square space 14 are arranged at equal intervals from top to bottom. A plurality of positioning grooves 13 are arranged at equal intervals from top to bottom on one side of each vertical plate 11.

[0022] In Example 1, the horizontal width of each positioning groove 13 on each vertical plate 11 is smaller than the horizontal width of the vertical plate 11, so as to form a gap 15 between two adjacent columns of inclined plates 2 on the left and right. Two adjacent inclined plates 2 up and down enclose a water flow channel 15 for horizontal flow.

[0023] By adjusting the width of the inclined plate 2, the residence time of the water flow can be controlled. For example, when the sedimentation separation device is applied to a general water supply system, the width of the inclined plate 2 can be designed to be 3-6 cm; when applied to a sewage treatment system, the width of the inclined plate 2 can be designed to be 7-19 cm.

[0024] During the use of the sedimentation separation device in Example 1, the water flow enters each water flow channel 15 for horizontal flow horizontally from the side of the device. The sludge in the water flow precipitates along each inclined plate 2 and falls vertically through the gap between two columns of inclined plates 2.

[0025] The sedimentation separation device in Example 2 is a sedimentation separation device with upward flow sludge discharge. The difference between this sedimentation separation device and the sedimentation separation device in Example 1 is that, as Figures 4 to 6 shown, the horizontal width of each positioning groove 13 on each vertical plate 11 is equal to the horizontal width of the vertical plate 11. Two adjacent inclined plates 2 up and down enclose an upward flow water flow sub-channel 16. The adjacent upward flow water flow sub-channels 16 on the left and right are sequentially communicated and form an upward flow water flow channel 17 (for example, Figure 5 the 3 upward flow water flow sub-channels 16 in the upper right corner in [figure] are sequentially communicated and form an upward flow water flow channel 17). The surfaces of the inclined plates 2 at the bottom of each upward flow water flow channel 17 are on the same inclined plane.

[0026] During the use of the sedimentation separation device in Example 2, the water flow enters each upward flow water flow channel 17 from the bottom of the device. The sludge in the water flow precipitates along each inclined plate 2 and slides down.

[0027] Each component of the above sedimentation separation device can be transported separately to the use site and assembled at the use site, rather than completing the assembly of the entire sedimentation separation device before leaving the factory, thereby reducing the transportation difficulty, improving the convenience and efficiency of transportation, and improving the assembly accuracy of the device.
