Description

Technical Field

[0001] The utility model relates to the technical field of pipe chain conveying, in particular to a pipe chain conveying pipe and a pipe chain conveying device. Background Art

[0002] The pipe chain conveyor system is a continuous conveying device for bulk materials such as powders, granules, and small blocks. It can be conveyed in a combination of horizontal, inclined, and vertical modes. It is generally used in the fine chemical, pesticide and mineral, building materials, and food industries. It has the advantages of being sealed and dust-free, environmentally friendly and safe, and highly efficient. However, in actual use, due to the direct contact between the scraper and the inner wall of the pipe chain, conveying can only be achieved by hard grinding between the scraper and the pipe. This method cannot effectively control noise, and it generates loud noise during movement. The scraper is also prone to wear, resulting in unclean material conveying or pipe chain jamming.

[0003] In this regard, Chinese utility model patent application number CN201921257877.3 discloses a pipe chain conveyor and pipe chain conveyor equipment. At least three rollers are arranged circumferentially around each circular scraper. These rollers are rollably supported on the inner circumference of the pipe. This technical solution allows the rollers to rest on the inner circumference of the pipe, at least partially converting the sliding friction between the scraper and the pipe into rolling friction between the rollers and the pipe, thereby reducing friction on the scraper.

[0004] However, in actual applications, it was found that when conveying powdered materials, the material powder could easily enter the installation groove of the roller, causing the roller to have poor rotation performance or even unable to rotate, thereby weakening the expected effect of the roller in reducing friction. Utility Model Content

[0005] The purpose of the present utility model is to overcome the above-mentioned technical deficiencies and propose a pipe chain conveying pipe and a pipe chain conveying device to solve the technical problem in the prior art that material powder can easily enter the mounting groove of the roller, causing the roller's rotation performance to deteriorate or even be unable to rotate, thereby weakening the roller's expected effect in reducing friction.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] In order to solve the technical problem that material powder can easily enter the mounting groove of the roller, causing the roller's rotation to deteriorate or even become unable to rotate, thereby weakening the expected effect of the roller in reducing friction, the utility model provides a pipe chain conveying pipe and a pipe chain conveying device, which can prevent material powder from entering the mounting groove of the roller and ensure the flexibility of the roller rotation.

[0027] See also Figure 1-Figure 3 , Figure 1 Schematic diagram of the structure of a pipe chain conveying pipe and a pipe chain conveying device in one embodiment of the present invention. The pipe chain conveying pipe and the pipe chain conveying device include a pipeline 1, a scraping mechanism 2 and a plurality of chains 3.

[0028] The scraping mechanism 2 includes a plurality of scrapers 21 and a plurality of first brushes 22. Each of the scrapers 21 is slidably arranged in the pipe 1 at equal intervals. A mounting groove 211 is provided on the outer wall of each scraper 21. A ball 23 is movably arranged in each mounting groove 211. The ball 23 abuts against the inner wall of the pipe 1. The first brush 22 is fixed to the outer wall of the corresponding scraper 21 and is used to abut against the inner wall of the pipe 1. The first brush 22 is located in front of the moving direction of the ball 23.

[0029] The chain 3 is used to connect two adjacent scrapers 21 .

[0030] During use, an external driving device drives each scraper 21 and chain 3 to move in the pipe 1, thereby driving the material between the two adjacent scrapers 21 to move along the pipe 1 to realize the transportation of the material. In addition, since the scraper 21 does not directly contact the inner wall of the pipe 1, but contacts the inner wall of the pipe 1 through the ball 23, when the scraper 21 moves, the ball 23 rotates accordingly, thereby reducing the friction between the scraper 21 and the inner wall of the pipe 1. At the same time, since a first brush 22 is provided in front of the moving direction of the ball 23, the first brush 22 can scrape off the powder attached to the inner wall of the pipe 1, thereby preventing the powder from entering the mounting groove 211 and causing the rotation performance of the ball 23 to deteriorate, and at the same time preventing the powder material from remaining in the pipe, thereby improving the efficiency and cleanliness of material transportation.

[0031] In one embodiment, see Figure 1 and Figure 2 The first brush 22 includes a first brush base 221 and a first brush body 222. The first brush base 221 is fixed to the outer wall of the scraper 21. One end of the first brush body 222 is fixed to the first brush base 221, and the other end of the first brush body 222 is used to abut the inner wall of the pipe 1. In this embodiment, the first brush base 221 is fixed to the outer wall of the scraper 21 via a plurality of screws, thereby facilitating replacement of the first brush 22.

[0032] In one embodiment, see Figure 1 and Figure 2The scraper mechanism 2 also includes a second brush 24, which is fixed to the outer wall of the corresponding scraper 21 and is used to abut against the inner wall of the pipe 1. The second brush 24 is located behind the moving direction of the ball 23, thereby preventing powder material from entering the mounting groove 211 from the rear.

[0033] In one embodiment, see Figure 1 and Figure 2 The second brush 24 includes a second brush base 241 and a second brush body 242. The second brush base 241 is fixed to the outer wall of the scraper 21. One end of the second brush body 242 is fixed to the second brush base 241, and the other end of the second brush body 242 is used to abut the inner wall of the pipe 1. In this embodiment, the second brush base 241 is fixed to the outer wall of the scraper 21 via a plurality of screws, thereby facilitating replacement of the second brush 24.

[0034] In one embodiment, see Figure 1 and Figure 2 A first connecting ear 25 and a second connecting ear 26 are respectively formed at both ends of each scraper 21. One end of the chain 3 is fixedly connected to the first connecting ear 25 of the scraper 21 on one side, and the other end of the chain 3 is fixedly connected to the second connecting ear 26 of the scraper 21 on the other side.

[0035] In one embodiment, see Figure 1 and Figure 2 A first fixing hole is formed on the first connecting ear 25, and a first fixing pin 301 is formed at one end of the chain 3, and the first fixing pin 301 is inserted into the first fixing hole.

[0036] In one embodiment, see Figure 1 and Figure 2 A second fixing hole is formed on the second connecting ear 26, and a second fixing pin 302 is formed on the other end of the chain 3. The second fixing pin 302 is inserted into the second fixing hole.

[0037] In one embodiment, see Figure 1 and Figure 2 The chain 3 includes a plurality of connection blocks 31 and a plurality of connection bars 32 arranged at intervals, and the two ends of the connection bars 32 are respectively hinged to two adjacent connection blocks 31. In this embodiment, each of the chains 3 includes two connection blocks 31 and three connection bars 32.

[0038] The utility model also provides a pipe chain conveying device, comprising the pipe chain conveying pipe.

[0039] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail: when in use, the external driving device drives each scraper 21 and the chain 3 to move in the pipe 1, thereby driving the material between the two adjacent scrapers 21 to move along the pipe 1, thereby realizing the transportation of the material, and since the scraper 21 does not directly contact the inner wall of the pipe 1, but contacts the inner wall of the pipe 1 through the ball 23, when the scraper 21 moves, the ball 23 rotates accordingly, thereby reducing the magnitude of the friction between the scraper 21 and the inner wall of the pipe 1. At the same time, since a first brush 22 is provided in front of the moving direction of the ball 23, the first brush 22 can scrape off the powder attached to the inner wall of the pipe 1, thereby preventing the powder from entering the mounting groove 211 and causing the rotation performance of the ball 23 to deteriorate, and at the same time preventing the powder material from remaining in the pipe, thereby improving the efficiency and cleanliness of material transportation.
