Description

Technical Field

[0001] This utility model relates to the field of sludge suction machine technology, specifically to a sludge suction flow rate adjustment device for a single-tube sludge suction machine. Background Technology

[0002] A single-pipe sludge suction machine is a specialized device used to clean sludge from the bottom of sedimentation tanks, water storage tanks, and other water bodies. Its core function is to extract, transport, and discharge sludge through a single pipe, ensuring the continuous and efficient operation of the water treatment system. The sludge suction flow regulating device is used to adjust the sludge flow rate in the suction pipe. The sludge suction flow regulating device typically consists of an outer and an inner regulating cylinder nested within each other. The flange of the inner regulating cylinder is welded and fixed to the bottom surface of the sludge collection tank and connected to the upper flange of the suction pipe opening. The sludge suction flow regulating device adjusts the water flow area of ​​the outlet by rotating it, thereby regulating the sludge flow rate in the suction pipe.

[0003] For example, Chinese patent CN219002079U, entitled "A Single-Pipe Sludge Suction Machine," includes a sludge discharge pipeline system, a guide rail system, and a traction control system. The guide rail system includes a square tube track, track supports, and a sludge suction trolley. Several guide rail supports are evenly installed and fixed in the middle of the bottom of a sedimentation tank. A square tube guide rail is installed on top of the guide rail supports, located in the center of the sedimentation tank and running through the entire tank. The sludge suction trolley can slide along the square tube guide rail. The sludge discharge pipeline system includes a sludge discharge hose, a rigid sludge discharge pipe, and a sludge discharge valve. A perforated sludge discharge pipe is installed on the square tube track, with the perforated sludge discharge pipe having a central... The top of the suction trolley is connected to the sludge discharge hose via a flange. The other end of the sludge discharge hose is connected to a rigid sludge discharge pipe installed on the wall of the sedimentation tank. The rigid sludge discharge pipe passes through the wall of the sedimentation tank and is connected to a sludge discharge valve outside the tank. The sludge discharge valve is connected to a sludge discharge ditch via a pipe. The middle part of the perforated sludge discharge pipe is fixed to the top of the suction trolley. The traction control system includes a drive mechanism, rollers, guide pulleys, a tensioning device, and a wire rope. The two ends of the wire rope are respectively connected to the holes at both ends of the suction trolley. There are two guide pulleys, located at both ends of the bottom of the sedimentation tank. The drive mechanism is located on the top of one side wall of the sedimentation tank.

[0004] While the existing technologies described above enable the use of sludge suction machines, in practical applications, it is difficult to adjust the sludge suction flow rate. Typically, the sludge suction capacity is fixed, leading to energy waste when the suction capacity does not match the sludge volume. Furthermore, the adjustment mechanism is not easily disassembled, as it is usually fixedly connected to the sludge suction machine, requiring the disassembly and reassembly of the entire fixed structure to replace it, thus increasing the workload of operators. Therefore, these technologies do not meet current needs. To address this, we propose a sludge suction flow rate adjustment device for a single-tube sludge suction machine. Utility Model Content

[0005] The purpose of this utility model is to provide a mud suction flow rate adjustment device for a single-tube mud suction machine, so as to solve the problems mentioned in the background art of difficulty in adjusting the mud suction flow rate of the mud suction machine and the inconvenience of disassembling and assembling the adjustment mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sludge suction flow rate regulating device for a single-tube sludge suction machine, comprising a regulating device body, a connecting cavity provided at the center of the regulating device body, and telescopic cavities provided at both the front and rear ends of the connecting cavity. The telescopic cavities are open structures and communicate with the connecting cavity. A first sliding plate is provided inside the telescopic cavity at the rear end of the connecting cavity, the first sliding plate slides with the telescopic cavity, and one end of the first sliding plate extends into the connecting cavity. A second sliding plate is provided inside the telescopic cavity at the front end of the connecting cavity, the second sliding plate slides with the telescopic cavity, and one end of the second sliding plate extends into the connecting cavity.

[0007] Preferably, hydraulic telescopic devices are fixedly installed at both the front and rear ends of the main body of the adjusting device. The telescopic ends of the hydraulic telescopic devices extend into the telescopic cavity, and the telescopic ends of the hydraulic telescopic devices are fixedly connected to the first sliding plate and the second sliding plate.

[0008] Preferably, slots are provided on both sides inside the body of the adjusting device, and the slots are connected to the connecting cavity. Connecting pipes are provided on both sides outside the body of the adjusting device, and the connecting pipe on the side closer to the body of the adjusting device extends to the slot. Flanges are fixedly provided on both sides of the connecting pipes, and several through holes are provided inside the flanges, which are distributed in a ring at equal intervals.

[0009] Preferably, the adjusting device body has several threaded holes inside the slot on one side, the threaded holes corresponding to the through holes, and bolts are provided on the outside of the flange, the bolts extending through the through holes into the threaded holes.

[0010] Preferably, the front end of the first sliding plate is fixedly provided with five positioning rods, which are evenly distributed, and the interior of the second sliding plate is provided with five positioning holes, which correspond to the positions of the positioning rods.

[0011] Preferably, a sealing ring is fixedly provided on one side of the outer side of the flange, and the sealing ring is in pressure contact with the inner wall of the slot.

[0012] Preferably, a flow meter is fixedly installed at the upper end of the outside of the connecting pipe, and the probe structure of the flow meter extends into the inside of the connecting pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can adjust the flow rate of sludge suction by means of the first sliding plate and the second sliding plate. When the sludge suction flow rate needs to be adjusted, the main body of the adjustment device needs to be closed. The hydraulic telescopic device is opened so that the telescopic end of the hydraulic telescopic device extends. The extension of the telescopic end of the hydraulic telescopic device pushes the first sliding plate and the second sliding plate to slide in the telescopic cavity, so that the first sliding plate and the second sliding plate block the opening of the connecting cavity, thereby realizing the adjustment of the sludge suction flow rate. At the same time, the inner wall of the telescopic cavity provides support for the first sliding plate and the second sliding plate. Meanwhile, the operator observes the data on the flow meter and adjusts the first sliding plate and the second sliding plate to the appropriate position, thereby improving the energy utilization rate.

[0015] (2) This utility model allows for the disassembly and assembly of the regulating device body and the connecting pipe through the slot and flange. When the regulating device body needs to be replaced, the operator rotates the bolt, causing the bolt to move outward through the threaded hole until the bolt comes out of the through hole. Then, the regulating device body is removed from between the connecting pipes. At this time, the new regulating device body is placed between the connecting pipes, and the flange on the connecting pipe enters the slot. The bolt is then aligned with the through hole and rotated, causing the bolt to re-enter the threaded hole and complete the fixing of the regulating device body, thereby improving the convenience of disassembly and assembly of the regulating device body.

[0016] (3) This utility model can improve the stability of the first sliding plate and the second sliding plate by using the positioning rod and positioning hole. When the sludge suction flow rate needs to be adjusted, the main body of the adjustment device needs to be closed. The hydraulic telescopic device is opened so that the telescopic end of the hydraulic telescopic device extends. The extension of the telescopic end of the hydraulic telescopic device pushes the first sliding plate and the second sliding plate to slide in the telescopic cavity, so that the first sliding plate and the second sliding plate block the opening of the connecting cavity. The hydraulic telescopic device continues to extend until the first sliding plate and the second sliding plate contact each other. At this time, the positioning rod on the first sliding plate enters the positioning hole. The sludge sucked in passes through the gap between the first sliding plate and the second sliding plate. The positioning rod and the positioning hole reinforce the first sliding plate and the second sliding plate at multiple points to avoid damage to the first sliding plate and the second sliding plate caused by excessive impact force.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The regulating device body 1 has telescopic chambers 13 located inside the front and rear ends of the connecting cavity 8. The telescopic chambers 13 are open and communicate with the connecting cavity 8. A first sliding plate 9 is located inside the telescopic chamber 13 at the rear end of the connecting cavity 8. The first sliding plate 9 slides with the telescopic chamber 13 and one end of the first sliding plate 9 extends into the connecting cavity 8. A second sliding plate 14 is located inside the telescopic chamber 13 at the front end of the connecting cavity 8. The second sliding plate 14 slides with the telescopic chamber 13 and one end of the second sliding plate 14 extends into the connecting cavity 8. Hydraulic telescopic devices 4 are fixedly installed at the front and rear ends of the regulating device body 1. The telescopic ends of the hydraulic telescopic devices 4 extend into the telescopic chambers 13 and are fixedly connected to the first sliding plate 9 and the second sliding plate 14, so as to facilitate the adjustment of the sludge suction amount through the first sliding plate 9 and the second sliding plate 14.

[0025] Please see Figure 2 and Figure 4The regulating device body 1 has slots 6 on both sides inside, which are connected to the connecting cavity 8. The regulating device body 1 has connecting pipes 2 on both sides outside, with the connecting pipe 2 on the side closer to the regulating device body 1 extending to the slot 6.

[0027] Working principle: In use, the hydraulic telescopic device 4 is activated, causing its telescopic end to extend. This extension pushes the first sliding plate 9 and the second sliding plate 14 to slide within the telescopic cavity 13, thus blocking the opening of the connecting cavity 8 and adjusting the sludge suction flow rate.

If the hydraulic telescopic device 4 continues to extend until the first sliding plate 9 and the second sliding plate 14 contact, the positioning rod 10 on the first sliding plate 9 will...
