Abstract
Description
Technical Field
[0001] This utility model relates to the field of horizontal flow sedimentation tank technology, and specifically to a sludge removal device for a horizontal flow sedimentation tank. Background Technology
[0002] Horizontal flow sedimentation tanks are widely used in drinking water treatment due to their simple structure, convenient management, good resistance to shock loads, and stable operation. Raw water, after being slowly treated with a water purification agent and undergoing flocculation reaction at the baffle plate, enters the horizontal flow sedimentation tank. A large amount of sludge is generated daily and settles in the tank, making routine sludge removal essential.
[0003] In Chinese patent announcement number CN219399074U, a horizontal flow sedimentation tank with a sludge removal device is disclosed. The tank body has an inlet end and an outlet end, and a sludge removal pipe with the corresponding outlet end set at the bottom of the tank body. The sludge removal pipe is laid perpendicular to the liquid flow direction, passes through the tank body, and the outlet of the sludge removal pipe is located outside the tank body. The pipe wall has multiple through holes for sludge and water to pass through, which solves the problem of sludge accumulation affecting the water quality and turbidity of the effluent.
[0004] Compared to the above-mentioned sludge discharge device, the following defects still exist: before sludge discharge, it is impossible to measure the sludge height in the sedimentation tank, resulting in sludge being discharged before reaching the state where it can be discharged, wasting resources. It solves the problem that the concentration of sludge discharge water cannot be controlled during the sludge discharge process, and it is easy to produce clear water. At the same time, it solves the problem that it is impossible to accurately position the sludge discharge machine before it discharges sludge, which can easily cause the sludge discharge machine to exceed the sludge discharge range.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0030] Example 1
[0031] Please see Figure 1 , Figure 3 and Figure 4 As shown, this utility model is a sludge discharge device for a horizontal flow sedimentation tank. Specifically, it can measure the sludge height in the liquid level flow 3 to avoid wasting resources when the sludge has not reached the dischargeable state. It can also stably connect the sludge level gauge body 14 to facilitate height adjustment. The device includes a sedimentation tank body 1; a truss 4 set at the upper end of the sedimentation tank body 1; a rangefinder baffle 5 set on both the left and right sides of the upper surface of the truss 4; a gantry 7 set above the truss 4; fixed mounting brackets 11 installed on both the left and right sides of the upper end of the gantry 7; a sludge interface meter 12 set at the left end of the fixed mounting bracket 11; a sensor cable 13 set on the outside of the sludge interface meter 12; a sludge level gauge body 14 set at the lower end of the sensor cable 13; and a fastening component 15 connected to the gantry 7 set on the outside of the sludge level gauge body 14.
[0032] In this embodiment, preferably, the sludge interface meter 12 is integrally connected to the sludge level gauge body 14 via a sensor cable 13. The sensor cable 13 can be extended to 200m. A liquid level flow 3 is provided inside the sedimentation tank body 1. The lower end surface of the sludge level gauge body 14 is mounted on the lower side of the liquid level flow 3. The fastening assembly 15 consists of a first mounting bracket 1501, a second mounting bracket 1502, a rubber pad 1503, an adjusting bolt 1504, a first rubber ring 1505, a second rubber ring 1506, and an adjusting nut 1507. The second mounting bracket 1502 is provided on the right side of the first mounting bracket 1501. Rubber pads 1503 are provided on the inner sides of both the first mounting bracket 1501 and the second mounting bracket 1502. An adjusting bolt 1504 is provided at the connection between the first mounting bracket 1501 and the second mounting bracket 1502. The outer end of the adjusting bolt 1504... A second rubber ring 1506 and a first rubber ring 1505 are respectively provided on the left and right sides. An adjusting nut 1507 connected to the adjusting bolt 1504 is provided on the left side of the second rubber ring 1506. The first mounting bracket 1501 and the second mounting bracket 1502 are both connected to the rubber pad 1503 by adhesive bonding. The inner wall surface of the rubber pad 1503 is fitted to the outer surface of the sludge level gauge body 14. The first rubber ring 1505 and the second rubber ring 1506 are both connected to the adjusting bolt 1504 by sleeve connection. The adjusting bolt 1504 passes through the second mounting bracket 1502 and the first mounting bracket 1501 in sequence and is connected to the adjusting nut 1507 by thread. Under the action of the fastening component 15, the sludge level gauge body 14 can be stably connected and installed as a whole, and the height position can be adjusted as needed.
[0033] In summary, the sludge level gauge body 14, connected to the sludge interface meter 12 via sensor cable 13, is engaged and limited inside the rubber pad 1503. At this time, the first rubber ring 1505 and the second rubber ring 1506 are fitted onto the outside of the adjusting bolt 1504. The adjusting bolt 1504 passes through the second mounting bracket 1502 and the first mounting bracket 1501 in sequence, and is threadedly connected to the adjusting nut 1507. This allows for height adjustment and secure installation of the sludge level gauge body 14 as needed, preventing it from falling off. When the gantry crane 7 moves laterally, the sludge level gauge body 14 moves synchronously with the gantry crane 7. When the predetermined total sludge volume is reached... Afterwards, the sludge discharge machine 16 runs empty once. Based on the sludge level gauge 14, the sludge height at different points on the bottom of the sedimentation tank 1 is plotted and a trend chart is generated and displayed on the automatic control page. Then, sludge discharge begins. The sludge discharge is controlled by setting different forward frequencies of the gantry crane 7 according to the sludge height in different intervals to control the travel speed and start and stop of the sludge discharge machine 16. The sludge discharge work is mainly completed by two variables: sludge level height and gantry crane 7 frequency, so that no clear water is produced, avoiding loss and waste of resources. The sludge concentration meter 2 is a YSI6820 multi-parameter water quality monitor, and the sludge interface meter 12, sensor cable 13 and sludge level gauge 14 are Sludge finder2.

[0036] In this embodiment, preferably, a limiting groove 6 is provided on the inner side of the truss 4, the upper surface of the limiting groove 6 is fitted with the lower surface of the drive wheel 8, the truss 7 is fixedly connected to the step frame 9, and the lower surface of the step frame 9 is higher than the horizontal plane of the liquid level flow 3, which can make the truss 7 move more stably in the lateral direction and avoid dislocation.
[0037] In this embodiment, preferably, a buffer tank is provided at the lower end of the sludge discharge pipe 17, and a sludge concentration meter 2 is provided inside the buffer tank, which can prevent mud and water from splashing during the sludge discharge process under the action of the buffer tank.
[0038] In summary, when the drive wheel 8 is opened, the gantry 7 can be moved as a whole. The lower surface of the drive wheel 8 is fitted with the limiting groove 6 opened on the inner side of the gantry 4, which can prevent the gantry 7 from dislodging. In addition, the rangefinder body 10 is set on the lower side of both the left and right ends of the gantry 7. It can be blocked by the rangefinder baffle 5 to prevent it from exceeding the range, thus accurately positioning the sludge discharge machine body 16. Finally, the sludge discharge machine body 16 can be opened to discharge sludge using the sludge discharge pipe 17 and the sludge suction pipe 18. It can also be automatically or manually discharged in real time according to the feedback of the sludge concentration meter 2. The sludge concentration meter 2 is set in the buffer groove at the lower end of the sludge discharge pipe 17 to prevent mud and water from splashing during the sludge discharge process. By setting the concentration parameter, when the sludge discharge concentration is lower than the set value, the sludge discharge stops and moves to the next point for operation.
