Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the sludge conveying technical field, concretely relates to pipe type pneumatic negative pressure sludge conveying connecting piece device. BACKGROUND

[0002] In the field of modern sewage treatment, industrial sludge treatment, efficient sludge conveying is a key link. There are many traditional sludge conveying methods, such as gravity conveying, mechanical conveying and pneumatic conveying. Among them, although the gravity conveying has low cost, it is limited by topography and height difference, and the application scene is limited. Mechanical conveying, such as screw conveyor and scraper conveyor, is prone to mechanical part wear and blockage, and has high maintenance cost and limited efficiency.

[0003] As a relatively advanced conveying method, pneumatic conveying, especially pipe type pneumatic negative pressure conveying, has been widely used in sludge conveying due to its high conveying efficiency, good sealing performance and long-distance conveying. However, the current pipe type pneumatic negative pressure conveying system still has many problems in practical application.

[0004] Firstly, in the aspect of pipe connection, the existing connection method is mostly complex. The common welding connection method not only consumes time and effort in the installation process, but also is extremely inconvenient for maintenance and replacement of pipe components in the later period. Once a problem occurs, a lot of time and manpower is needed for cutting, re-welding and other operations. Some simple flange connection methods have poor sealing performance and are prone to air leakage during negative pressure conveying, which reduces the conveying efficiency and even causes the conveying to fail to proceed normally.

[0005] Secondly, in the aspect of adapting to different pipe diameters, the traditional conveying equipment lacks flexibility. In sewage treatment plants or industrial production, pipe diameters are various, and the existing sludge conveying device is difficult to stably and efficiently operate in pipes of different diameters. For example, the walking mechanism of some conveying equipment cannot be effectively adjusted according to the change of pipe diameter, which leads to the failure of normal walking in small-diameter pipes and unstable walking in large-diameter pipes, affecting the conveying effect.

[0014] Preferably, a sliding groove is provided on the outer wall of the connecting pipe, the sliding groove is arranged in the axial direction, and a guide block that cooperates with the sliding groove is provided on the inner wall of the movable collar.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] This invention enables rapid assembly of the connecting pipe through the splicing of connecting block one and connecting block two, along with the connecting protrusion and connecting groove. This facilitates installation and disassembly under different working conditions and provides a stable pipeline structure for subsequent sludge transportation. The centrally symmetrical design of connecting block one and connecting block two, as well as the cooperation of the connecting protrusion and connecting groove, makes the splicing process simple and accurate, reducing installation difficulty and time costs, and improving work efficiency.

[0018] This utility model's roller adjustment frame can flexibly adjust the spacing between the traveling wheels according to the inner diameter of the pipe, enabling the entire device to move stably within pipes of different specifications, thus expanding the applicability of the tubular pneumatic negative pressure sludge conveying system. The roller adjustment frame consists of a telescopic rod, a moving collar, an adjusting rod, and a connecting rod. Its simple structure allows for rapid and accurate adjustment, quickly adapting to changes in pipe diameter and improving the device's versatility.

[0019] This utility model's cutting mechanism cuts and breaks down sludge during the sludge conveying process, decomposing large, sticky sludge pieces into smaller particles. This reduces the risk of sludge clogging in the pipeline and ensures that the sludge can be smoothly conveyed through the connecting pipe. The motor of the cutting mechanism drives multiple cutting blades to rotate at high speed, resulting in a large cutting range and high efficiency. This effectively processes sludge, ensures smooth sludge conveying, and improves the overall working efficiency of the sludge conveying system.

[0020] The locking mechanism of this invention utilizes locking ring one, locking ring two, and an anti-slip ring to ensure the stability of the connecting pipe after splicing, preventing pipe separation due to pressure changes or mechanical vibration during negative pressure sludge transport, thus ensuring the continuity and stability of sludge transport. The bolt assembly fixing method of the locking mechanism is convenient to operate, and the anti-slip ring increases friction, greatly improving the reliability of the connecting pipe after splicing and reducing failures caused by loose connections.

[0034] See attached document Figs. 1-6 The tubular pneumatic negative pressure conveying sludge connector device includes a connecting pipe 1, which is composed of a semi-circular connecting block 11 and a connecting block 12 spliced ​​together. At least one locking mechanism 2 is provided on the outer side of the connecting pipe 1. Several roller adjustment frames 4 are equally spaced on the outer wall of the connecting pipe 1. A pair of traveling wheels 3 are rotatably installed on the output end of each roller adjustment frame 4. The roller adjustment frame 4 is used to adjust the distance between each pair of traveling wheels 3.

[0035] Connecting block 11 and connecting block 2 12 are centrally symmetrical. One end of connecting block 11 or connecting block 2 12 is provided with a connecting protrusion 13, and the other end is provided with a connecting groove 14. When connecting block 11 and connecting block 2 12 are spliced ​​into a ring, the connecting protrusion 13 can be embedded in the connecting groove 14.

[0036] The locking mechanism 2 includes a locking ring 1 21 and a locking ring 22 arranged symmetrically. Both ends of the locking ring 1 21 and the locking ring 22 have connecting ears 23. The connecting ears 23 of the locking ring 1 21 and the locking ring 22 are fixedly connected by a bolt assembly 24. Anti-slip rings 25 are provided on the inner walls of the locking ring 1 21 and the locking ring 22.

[0037] A cutting mechanism 5 is provided at one end of the connecting pipe 1. The cutting mechanism 5 includes a connecting ring 51 fixed at one end of the connecting pipe 1, an installation pipe 52 fixedly provided on the connecting ring 51, a motor 53 provided at the center of the installation pipe 52, and a number of cutting blades 54 evenly arranged on the output end of the motor 53.

[0038] The roller adjusting frame 4 includes a movable collar 41 slidably sleeved on the connecting pipe 1. Several telescopic rods 42 are evenly spaced on the connecting pipe 1, with the output end of each telescopic rod 42 connected to the movable collar 41. Several mounting seats 43 are also provided on the connecting pipe 1, with connecting rods 44 rotatably mounted on each mounting seat 43. The other end of each connecting rod 44 is connected to a mounting rod 45. An adjusting rod 46 is rotatably mounted on the movable collar 41, with the other end of each adjusting rod 46 rotatably connected to a connecting rod 44. A sliding groove 47 is formed on the outer wall of the connecting pipe 1, arranged axially. A guide block that mates with the sliding groove 47 is provided on the inner wall of the movable collar 41.

[0039] Working principle:

[0040] The operator first aligns connecting block 11 and connecting block 2 12. Since one end of connecting block 11 or connecting block 2 12 is provided with a connecting protrusion 13 and the other end is provided with a connecting groove 14, and the two are centrally symmetrical, during splicing, it is only necessary to accurately align the connecting protrusion 13 with the connecting groove 14 and forcefully insert it, so that the splicing process has a certain guiding effect, and the splicing can be completed quickly and accurately to form a complete annular connecting pipe 1.

[0041] Next, the locking rings 21 and 22 of the locking mechanism 2 are wrapped around both sides of the connecting pipe 1. The connecting lugs 23 at both ends of the locking rings 21 and 22 are aligned. The operator then uses the bolt assembly 24 to pass through and tighten the aligned connecting lugs 23. As the bolt assembly 24 tightens, the locking rings 21 and 22 gradually tighten, and the anti-slip rings 25 on their inner walls fit tightly against the outer wall of the connecting pipe 1. The anti-slip rings 25 are generally made of materials with a high coefficient of friction, such as rubber. They effectively increase the friction between the locking rings and the connecting pipe 1, preventing the locking mechanism 2 from loosening during subsequent operations, thus ensuring the stability of the connected pipe 1 after assembly.

[0042] On the outer wall of the connecting pipe 1, roller adjustment frames 4 are installed at pre-designed equidistant positions. Each roller adjustment frame 4 has a pair of traveling wheels 3 installed at its output end via rotating connectors such as bearings, ensuring that the traveling wheels 3 can rotate flexibly and providing a basis for the movement of subsequent devices within the pipeline.

[0043] When the device needs to enter a pipe with a larger diameter, the control system sends an extension command to the telescopic rod 42. The output end of the telescopic rod 42 begins to extend, pushing the movable collar 41 connected to it. Because the inner wall of the movable collar 41 is provided with a guide block that cooperates with the sliding groove 47 on the outer wall of the connecting pipe 1, the movable collar 41 can only move along the axial direction of the sliding groove 47. As the movable collar 41 moves, the adjusting rod 46 rotatably connected to it also begins to rotate. The rotation of the adjusting rod 46 drives the connecting rod 44 connected to it to rotate around the mounting base 43. The rotation of the connecting rod 44 changes its angle with the mounting rod 45, causing the mounting rod 45 to open outward, thereby increasing the distance between the pair of traveling wheels 3 mounted on the mounting rod 45 to accommodate pipes with larger diameters.

[0044] When the device needs to enter a pipe with a smaller diameter, the telescopic rod 42 receives a retraction command. The output end of the telescopic rod 42 retracts, pulling the moving collar 41 to move in the opposite direction along the slide groove 47. The reverse movement of the moving collar 41 causes the adjusting rod 46 to rotate in the opposite direction, which in turn drives the connecting rod 44 to rotate in the opposite direction, making the angle between the connecting rod 44 and the mounting rod 45 smaller. The mounting rod 45 retracts inward, ultimately reducing the distance between each pair of traveling wheels 3, so that the device can smoothly enter the small-diameter pipe.

[0045] The device moves within the pipeline driven by the traveling wheels 3. When it encounters sludge, the control system activates the cutting mechanism 5. The motor 53, located at the center of the mounting pipe 52 on the connecting ring 51 at one end of the connecting pipe 1, starts operating. The output shaft of the motor 53 rotates at high speed, driving several cutting blades 54, which are equidistantly positioned at the output end, to rotate synchronously at high speed. The high-speed rotating cutting blades 54 cut and break down the encountered sludge, decomposing large pieces of sludge into smaller particles, reducing the sludge's stickiness and agglomeration, and facilitating subsequent transportation.

[0046] While the cutting blade 54 cuts the sludge, the tubular pneumatic negative pressure system starts working, creating a negative pressure environment inside the connecting pipe 1. Under the action of negative pressure, the cut sludge is sucked into the connecting pipe 1 and transported along the connecting pipe 1 to a designated location, such as sludge treatment equipment or storage container.

[0047] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
