Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a scum removal device suitable for a horizontal flow sedimentation tank. Background Art

[0002] A horizontal flow sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is mainly composed of a tank body, water inlet and outlet, a water flow part and a sludge hopper. It is mainly used to treat domestic and industrial sewage. It was found during the operation of the water plant that when there are more algae in the water source, the raw water will be pre-oxidized to kill algae, and a large amount of scum will appear in the sedimentation tank. If it is not removed in time, the scum will enter the filter tank and increase the burden on the filter tank operation.

[0003] In the existing advection sedimentation tank, the staff uses a mesh to salvage and clean the scum in the advection sedimentation tank. However, since the manual cleaning of the scum is cumbersome, time-consuming and labor-intensive, the labor intensity of the staff is relatively high.

[0004] Therefore, a scum removal device suitable for a horizontal flow sedimentation tank has been developed, which can automatically clean the scum in the horizontal flow sedimentation tank and reduce the labor intensity of the staff. Utility Model Content

[0005] In order to overcome the shortcomings of existing advection sedimentation tanks, in which manual cleaning of scum is cumbersome, time-consuming and labor-intensive, resulting in high labor intensity for workers, the utility model provides a scum removal device suitable for advection sedimentation tanks that can automatically clean scum in the advection sedimentation tank and reduce the labor intensity of workers.

[0006] The technical solution is: a scum removal device suitable for a horizontal flow sedimentation tank, including a base, a sedimentation tank, a first fixed frame, a motor, a screw, a guide rod, a sliding frame, a scraper and a removal mechanism. The upper side of the base is connected to the sedimentation tank, and a plurality of mud discharge grooves are opened on the lower rear side of the sedimentation tank.

[0010] Furthermore, a slag inlet is provided on the transverse pipe.

The front sides of the left and right parts of the fixed block are connected to the mounting blocks, the mounting blocks are connected to the support rods, and the lower sides of the support rods are rotatably connected to the guide plates.

[0012] The beneficial effects of the utility model are as follows: 1.

DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] A scum removal device suitable for use in an advection sedimentation tank, such as Figure 1 and Figure 2 As shown, it includes a base 1, a sedimentation tank 2, a first fixed frame 4, a motor 5, a screw 6, a guide rod 7, a sliding frame 8, a scraper 9 and a removal mechanism 10. The upper side of the base 1 is connected to the sedimentation tank 2, and a collecting trough is opened on the base 1 to collect scum. Four mud discharge troughs 3 are opened on the lower rear side of the sedimentation tank 2. The right rear side of the sedimentation tank 2 is connected to the first fixed frame 4, and the motor 5 is connected to the first fixed frame 4. The output shaft of the motor 5 is connected to the screw 6, and the screw 6 is rotatably connected to the sedimentation tank 2. The upper left side of the sedimentation tank 2 is connected to the guide rod 7, and the rear of the screw 6 is threadedly connected to the sliding frame 8. The sliding frame 8 is slidably connected to the guide rod 7. Four scrapers 9 are connected to the lower side of the sliding frame 8. The scrapers 9 are T-shaped to facilitate scraping sludge. The removal mechanism 10 is provided on the sliding frame 8.

[0021] like Figure 1 and Figure 3 As shown, the removal mechanism 10 includes a second fixed frame 101, a self-priming pump 102, a fixed block 103, a main pipe 104, a vertical pipe 105 and a horizontal pipe 106. The second fixed frame 101 is connected to the right side of the rear of the sedimentation tank 2, and the second fixed frame 101 is connected to the self-priming pump 102. Three fixed blocks 103 are connected to the front side of the upper part of the sliding frame 8, and the main pipe 104 is connected between the fixed blocks 103. The main pipe 104 is connected to the self-priming pump 102, and four vertical pipes 105 are connected to the lower side of the main pipe 104. The front side of the middle part of the vertical pipe 105 is connected to the horizontal pipe 106, and the horizontal pipe 106 is provided with a slag inlet for facilitating the suction of the floating slag.

[0022] When using the utility model, firstly, the base 1 is placed in the working area of ​​the sedimentation tank 2 so that the base 1 supports the sedimentation tank 2, and then the motor 5 on the first fixed frame 4 is started to rotate the screw rod 6, so that the sliding frame 8 slides forward on the guide rod 7 and then slides backward, driving the scraper plate 9 to slide, and the sludge at the bottom of the sedimentation tank 2 is scraped off, and the scraped sludge is discharged from the mud discharge groove 3. When the sliding frame 8 slides, it drives the second fixed frame 101 to move, so that the self-priming pump 102 moves, and the self-priming pump 102 is started at the same time. Under the suction of the self-priming pump 102, the scum floating on the surface of the sedimentation tank 2 is sucked into the horizontal pipe 106 from the slag inlet, and then flows into the main pipe 104 through the vertical pipe 105, and then discharged through the self-priming pump 102, thereby playing the role of automatically cleaning the scum in the horizontal flow sedimentation tank 2 and reducing the labor intensity of the staff.

[0023] like Figure 1 and Figure 4As shown, it also includes a guide mechanism 11, which includes a mounting block 111, a support rod 112 and a guide plate 113.

When the sliding frame 8 moves, the mounting block 111 on the fixed block 103 is driven to move, the support rod 112 is moved, and the guide plate 113 is driven to move. Then, the water flow causes the guide plate 113 to rotate and guide the water flow to the cross pipe 106, thereby guiding the water flow through the guide plate 113 to prevent the scum from being missed.
