Description

Technical Field

[0001] This utility model relates to the field of primary sedimentation tank technology, specifically to the addition of a backflushing device to a primary sedimentation tank sludge machine. Background Technology

[0002] In the field of wastewater treatment, primary sedimentation tanks are key wastewater treatment facilities, mainly responsible for removing suspended solids (SS) from wastewater. Traditional intelligent control methods for primary sedimentation tank sludge discharge are often rather crude, usually controlling the sludge discharge volume by manually switching the sludge pump on and off or by simply controlling the sludge discharge rate over time.

[0003] Due to factors such as investment and land use, the surface load of primary sedimentation tanks in general wastewater treatment plants is usually set to a large value, resulting in a weaker ability to resist water quality and quantity shock loads.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent application date: 2022-09-09, publication number: CN217391664U) discloses a primary sedimentation tank, including a tank body, having an inlet channel and a sludge discharge channel, with an outlet at the top of the inlet channel; multiple baffles are provided, each baffle is circumferentially spaced on the inner wall of the tank body, and the inclination angle of the baffles can be adjusted relative to the overall water discharge direction of the outlet. Sewage flowing horizontally from the outlet will hit the baffles. Since the inclination angle of the baffles is adjustable, when the water in the tank body passes through the baffles with adjustable inclination angles, the obstruction of the baffles can change the inlet flow state of the primary sedimentation tank, preventing short-circuiting of the primary sedimentation tank under high water quality and high water volume load, and avoiding additional disturbance to the sedimentation process under low water quality and low water volume load, thereby improving the primary sedimentation tank's resistance to water quality and water volume shock loads.

[0005] While the above design can solve the aforementioned problems, it often encounters situations where the sludge concentration is too high and cannot be sucked out during operation. This requires emptying the primary sedimentation tank, manually flushing away the bottom sludge, and then refilling the tank. This operation is labor-intensive, time-consuming, and affects normal operation. In addition, converting the sludge suction machine into a sludge scraper requires redesigning and modifying the water tank and adding several regulating valves. In this environment, the regulating valves are prone to clogging, which is not conducive to the long-term operation of the system. Moreover, this solution is costly. Utility Model Content

[0006] The purpose of this utility model is to provide a backflushing device for the sludge suction machine in the primary sedimentation tank, so as to solve the problem mentioned in the background art where the sludge concentration is high and the sludge cannot be sucked out. The primary sedimentation tank must be emptied, the bottom sludge must be flushed away manually, and then water must be added again for operation. This operation is labor-intensive, time-consuming, and affects normal operation. At the same time, the sludge suction machine can be modified into a sludge scraper, but the water tank needs to be redesigned and modified, and several regulating valves need to be added. In this environment, the regulating valves are prone to clogging, which is not conducive to the long-term operation of the system. Moreover, this solution is expensive.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a backflushing device is added to the sludge machine in the primary sedimentation tank, including a support and lifting frame. A stabilizing block is installed on the inner surface of the support and lifting frame, and a stabilizing fitting mechanism for supporting the through-through sludge pipe is installed inside the stabilizing fitting block. The stabilizing fitting mechanism includes a stabilizing plate, and the through-through sludge pipe is correspondingly fitted and fixedly installed inside the stabilizing plate. A sludge discharge channel is installed on the side of the support and lifting frame, and an integrated fixing mechanism for stabilizing a DN40 valve is installed above the sludge discharge channel.

[0008] Furthermore, the integrated fixing mechanism includes a mud discharge pipe, which is fixedly installed on the outer surface of the right end opening of the through-output mud pipe, and the through-output mud pipe and the mud discharge pipe are internally connected.

[0009] Furthermore, the opening of the sludge discharge pipe corresponds to the opening position at the upper end of the sludge discharge channel, and the DN40 valve is fixedly installed on the outer surface of the left end opening of the through-output sludge pipe. Moreover, the through-output sludge pipe and the DN65 fire head are internally connected.

[0010] Furthermore, the through-output mud pipe is stably installed inside the stabilizing block, and two sets of stabilizing blocks and through-output mud pipe are symmetrically installed about the center point of the supporting lifting frame.

[0011] Furthermore, a suction pipe is installed on the lower surface of the through-through mud output pipe, and the through-through mud output pipe and the suction pipe are internally connected.

[0012] Furthermore, the inner surface of the stabilizing block contacts the outer surface of the through-output mud pipe to form a sliding structure, and the supporting lifting frame and the stabilizing block are designed as an integral unit.

[0013] Furthermore, a DN40 valve is installed on the upper surface of the through-output mud pipe, and the through-output mud pipe and the DN40 valve are internally connected. Moreover, the DN65 fire head is a water source output design.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the primary sedimentation tank sludge machine is equipped with a backflushing device. When sludge suction is required, the sludge suction pipe is directly started to suck in the sludge, so that the sludge is input into the sludge discharge pipe through the through-through sludge discharge pipe. After passing through the sludge discharge pipe, the sludge is transported to the sludge discharge channel for subsequent transportation. A small amount of sludge can be efficiently absorbed again by flushing with water from the DN65 fire head. This design makes the sludge easier to discharge, the refilling operation is less labor-intensive, faster, and does not affect normal operation.

[0015] Furthermore, when it is necessary to fix the through-through mud pipe, the through-through mud pipe can be placed directly inside the stable fixing block to obtain stable support. In addition, the five sets of mud suction pipes are uniformly embedded and installed inside the stable fixing plate, making the equipment more stable in use.

[0016] Furthermore, the DN65 fire hose reel features an output design, allowing water to be directly discharged and impact the interior of the primary sedimentation tank. The opening of the sludge discharge pipe also connects seamlessly with the interior of the sludge discharge channel, making the equipment more convenient to use. Attached Figure Description

[0024] 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 protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6This utility model provides the following technical solution: A backflushing device is added to the sludge machine in the primary sedimentation tank, including a support and lifting frame 1. A stabilizing block 2 is installed on the inner surface of the support and lifting frame 1, and a stabilizing fitting mechanism for supporting the through-through sludge pipe 3 is installed inside the stabilizing fitting mechanism. The stabilizing fitting mechanism includes a stabilizing plate 9, and the through-through sludge pipe 3 is correspondingly fitted and fixedly installed inside the stabilizing plate 9. A sludge discharge channel 7 is installed on the side of the support and lifting frame 1, and an integrated fixing mechanism for stabilizing the DN40 valve 4 is installed above the sludge discharge channel 7.

[0026] like Figure 2 , Figure 3 , Figure 4 The technical solution shown addresses the problem that when sludge concentration is high during operation, it is often impossible to extract sludge. This requires emptying the primary sedimentation tank, manually flushing away the bottom sludge, and then refilling with water, which is labor-intensive, time-consuming, and affects normal operation. The solution disclosed is as follows: the through-output sludge pipe 3 is embedded and stably installed inside the stabilizing block 2. The stabilizing block 2 and the through-output sludge pipe 3 are symmetrically installed in two sets about the internal center point of the supporting lifting frame 1. The lower surface of the through-output sludge pipe 3 is equipped with a suction pipe 8, and the through-output sludge pipe 3 and the suction pipe 8 are internally connected. The inner surface of the stabilizing block 2 and the outer surface of the through-output sludge pipe 3 are in contact to form a sliding structure. The supporting lifting frame 1 and the stabilizing block 2 are integrated into one piece.

[0027] When the through-output mud pipe 3 needs to be supported and stabilized during installation, first, the through-output mud pipe 3 is passed entirely through the interior of the support and lifting frame 1, and then placed downwards into the interior of the stabilizing block 2. The stabilizing block 2 will stabilize and fix the through-output mud pipe 3. Since the stabilizing block 2 is fixedly installed on the inner surface of the support and lifting frame 1, the installation of the through-output mud pipe 3 is more stable. As the through-output mud pipe 3 moves, the suction pipe 8 fixedly installed on the lower surface will move synchronously, and the movement of the suction pipe 8 will enter the interior of the stabilizing plate 9 fixedly installed on the lower surface of the support and lifting frame 1. The support of the stabilizing plate 9 will make the placement of the through-output mud pipe 3 and the stabilizing plate 9 more stable. Furthermore, the integrated design of the through-output mud pipe 3 and the suction pipe 8 makes the equipment more convenient to use.

[0028] Example 2: Figure 2 , Figure 3 , Figure 4The technical solution shown addresses the problem of converting a sludge suction machine into a sludge scraper, which requires redesigning and modifying the water tank and adding several regulating valves. These regulating valves are prone to clogging, hindering long-term system operation and resulting in high costs. The solution discloses the following: the opening of the sludge discharge pipe 6 corresponds to the upper opening of the sludge discharge channel 7; a DN40 valve 4 is fixedly installed on the outer surface of the left opening of the through-output sludge pipe 3; the through-output sludge pipe 3 and the DN65 fire head 5 are internally connected; the upper surface of the through-output sludge pipe 3 is equipped with a DN40 valve 4; the through-output sludge pipe 3 and the DN40 valve 4 are internally connected; and the DN65 fire head 5 is a water source output design.

[0029] When sludge needs to be absorbed and cleaned, the suction pipe 8 is first started to absorb upwards. The sludge will be absorbed through the suction pipe 8 and enter the interior of the through-output sludge pipe 3. Since the through-output sludge pipe 3 is internally connected to the sludge, it will continuously transport the sludge outwards. As the through-output sludge pipe 3 is driven, the sludge will enter the interior of the discharge pipe 6 fixed at the other end of the through-output sludge pipe 3. Since the discharge pipe 6 is also internally connected to the sludge, the sludge will flow through the interior of the discharge pipe 6 until it is discharged. The sludge will enter the interior of the discharge channel 7 through the opening of the discharge pipe 6. Since the discharge channel 7 is fixedly installed on the side of the supporting lifting frame 1, it will uniformly transport and collect the sludge. When a small amount of sludge cannot be collected and absorbed, the DN65 fire head 5 will output water to the interior of the primary sedimentation tank to impact the sludge for better collection.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
