Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a cleaning device for a chute and a chute. Background Technology

[0002] In China's coal industry, it is very common to transfer materials between equipment using chutes. Chutes vary in type depending on the environment and working conditions. Since the properties and moisture content of the materials passing through the chutes are different, especially for finer particles, moisture content has a significant impact on the transfer efficiency of the chutes. The angle and size of the chutes at each stage are designed to adapt to the changes in material properties. However, due to the large fluctuations in the moisture content of the materials, some stages cannot avoid chute blockage and wall adhesion.

[0003] In existing technologies, most methods prevent material blockage by installing a vibrating motor on the outer wall of the chute. Specifically, the vibrating motor vibrates continuously or intermittently, or it is based on a blockage sensor. When material blockage occurs, a feedback signal is sent to the vibrating motor, which then starts to push the material downward.

[0004] However, the use of vibratory motors results in significant noise and dust generation during operation, leading to substantial environmental pollution. Therefore, corresponding dust removal and noise reduction facilities are required, resulting in higher costs. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1: like Figures 1-6 As shown, one embodiment of the present invention provides a cleaning device for a chute. The chute 4 has multiple inner sidewalls. The cleaning device includes at least one set of scraping mechanisms. At least one inner sidewall of the chute 4 is provided with a scraping mechanism. The scraping mechanism includes a rotating part 1 and a scraper 2. The scraper 2 is located on one side of the inner wall of the chute 4. The scraper 2 can rotate around the axis of the rotating part 1 to scrape off the material adhering to the inner wall of the chute 4. One end of the scraper 2 is connected to the rotating part 1 via the connecting component 5, and the scraper 2 can be flipped relative to the rotating part 1 via the connecting component 5 so that the other end of the scraper 2 is away from the rotating part 1.

[0022] It should be noted that the rotating component 1 is capable of rotating relative to the inner wall of the chute 4.

[0023] By using the connecting component 5, the scraper 2 can be flipped relative to the rotating part 1, so that one end of the scraper 2 is away from the rotating part 1. This allows the scraper 2 to be retracted and placed inside the chute 4. Then, the scraper 2 can be flipped back and unfolded, so that the scraper 2 is located on one side of the inner wall of the chute 4. The scraper 2 can rotate around the axis of the rotating part 1, effectively scraping off the material adhering to the inner wall of the chute 4, significantly reducing the phenomenon of material sticking to the wall, improving the material conveying efficiency, and replacing the vibration of the vibrating motor. During the scraping process, the scraper 2 produces less noise and dust, reducing environmental pollution. No additional dust removal and noise reduction facilities are required, resulting in low cost.

[0024] Since the scraper 2 can be flipped and retracted, there is no need to cut the chute 4 over a large area. Only a through hole that allows the rotating part 1 to pass through needs to be opened on the inner wall of the chute 4 to place the scraper 2 inside the chute 4.

[0025] The scraper 2 is made of wear-resistant and corrosion-resistant alloy material to ensure long-term stability and durability. A gap is left between the scraper 2 and the corresponding inner wall to reduce wear on the inner wall of the chute 4.

[0026] Preferably, the scraper 2 is a slab-shaped scraper, which improves the scraping efficiency of the scraper 2.

[0027] Depending on the specific form of the chute 4 and the material conveying speed, a drive method that can be selected, such as drive by drive component 3 or automatic rotation with the material flow, can be chosen, offering strong adaptability. The automatic rotation drive method for material flow: The chute 4 has a material drop zone (the material drop zone is...) Figure 6 (In the rectangular channel area), at least three scrapers 2 are provided. The three scrapers 2 are evenly spaced around the axis of the rotating part 1, and at least one scraper 2 is located in the material dropping area. At this time, the rotating part 1 is rotatably connected to the inner wall of the chute 4 through the rotating shaft.

[0028] like Figure 6 As shown, the axis of the rotating component 1 is perpendicular to the falling direction of the material in the material dropping area. At least one scraper 2 is located in the material dropping area, but the axis of the rotating component 1 is not located in the material dropping area. This allows the falling material to directly impact the blade of the scraper 2. At least one scraper 2, under the impact force of the falling material and gravity, can rotate around the axis of the rotating component 1. This enables the scraper 2 to scrape the material adhering to the inner wall of the chute 4 without power drive. This automatic rotation drive method, compared to traditional vibratory motor vibration, eliminates the need for a vibratory motor and therefore eliminates the need for corresponding dust removal and noise reduction facilities, resulting in lower costs.

[0029] Drive method of driver component 3: such as Figure 1 As shown, the scraping mechanism also includes a drive component 3, which is connected to the rotating component 1 and is used to drive the rotating component 1 to rotate.

[0030] The driving component 3 includes a drive motor 301 and a reducer 302; The fixed end of the drive motor 301 is connected to a base, and the base is connected to the outer wall of the chute 4 by fasteners, which are locking bolts. The output end of the drive motor 301 is connected to the reducer 302, and the output shaft of the reducer 302 is connected to the rotating part 1.

[0031] The rotation of the drive motor 301 drives the reducer 302, which is fixedly connected to its output end, to rotate. This, in turn, drives the rotating component 1, which is connected to the output shaft of the reducer 302, to rotate. The scraper 2, connected to the rotating component 1, scrapes the material on the inner wall around the axis of the rotating component 1. By using the drive motor 301, the specific form of the chute 4 and the material conveying speed can be ignored, and the scraping effect can always be guaranteed, avoiding material blockage in the chute 4.

[0032] In this embodiment, the scraper 2 can continuously rotate and scrape the material under the drive of the drive component 3. Compared with the continuous operation of the vibrating motor, it has lower energy consumption. Compared with the intermittent operation of the vibrating motor, since the scraper 2 is constantly rotating to scrape off the material, it improves the flow state of the material in the chute 4. Therefore, it can reduce the occurrence of material blockage caused by the inability to clear the blockage in time, reduce the accumulation phenomenon, and improve the smoothness of conveying.

[0033] Because the drive component 3 drives the scraper 2 to rotate around the axis of the rotating component 1, it reduces equipment failures and downtime caused by material sticking to the wall, and reduces maintenance costs and manpower input.

[0034] The preferred scraper 2 is provided with four scrapers, which are arranged in a cross shape. Each scraper 2 is connected to the rotating part 1 through a connecting component 5.

[0035] According to one embodiment of the present invention, the connecting component 5 includes a limiting groove structure and an elastic buckle structure; A limiting groove structure is provided on the rotating part 1, and one end of the scraper 2 is located in the limiting groove structure; The elastic buckle structure is connected to the rotating part 1. The scraper 2 is provided with a positioning groove 203. The elastic buckle structure and the positioning groove 203 cooperate to fix one end of the scraper 2 in the limiting groove structure.

[0036] Preferably, the limiting groove structure includes a straight groove 501 and a rotating groove 502 that are connected to each other. The rotating part 1 is in the shape of a disk. The surface of the rotating part 1 is a plane and the side surface of the rotating part 1 is an annular curved surface. The straight groove 501 is opened on the surface of the rotating part 1. One end of the straight groove 501 penetrates the side surface of the rotating part 1. The bottom wall of the straight groove 501 is provided with the rotating groove 502. The rotating groove 502 is located on the side of the straight groove 501. The depth of the straight groove 501 is greater than the depth of the rotating groove 502. The length direction of the straight groove 501 is parallel to the inner wall of the chute 4.

[0037] The scraper 2 includes a scraping part 201 and a connecting part 202 connected to each other. The length direction of the scraping part 201 is perpendicular to the length direction of the connecting part 202, and the connecting part 202 is disposed in the rotating groove 502.

[0038] Furthermore, the connecting component 5 also includes a receiving groove 503 formed on the side wall of the straight groove 501; The elastic snap-fit ​​structure includes a spring 504 and a positioning block 505. One end of the spring 504 is connected to the bottom wall of the receiving groove 503, and the other end is connected to the positioning block 505. One end of the positioning block 505 is slidably connected in the receiving groove 503, and the other end is inserted into the positioning groove 203. It should be noted that the positioning groove 203 is an arc-shaped groove, and the part of the positioning block 505 inserted into the positioning groove 203 is arc-shaped. Preferably, the positioning block 505 can be spherical, or it can be an integrally formed cylinder and hemisphere. The hemisphere is used to insert into the positioning groove 203 to limit the movement of the scraper 2.

[0039] like Figure 3As shown, the rotating groove 502 is composed of two arc-shaped grooves, which are located on both sides of the straight groove 501 (one arc-shaped groove is on the upper right side, and the other arc-shaped groove is on the lower left side). The rotating groove 502 has a first sidewall and a second sidewall that are parallel to each other and are perpendicular to the length direction of the straight groove 501. The bottom wall of the straight groove 501 and the bottom wall of the rotating groove 502 are located in the same plane, and the connecting part 202 is a round rod.

[0040] Installation method: Hold the scraper part 201 and insert the connecting part 202 into the straight groove 501. After inserting it to the bottom, rotate the connecting part 202 into the rotating groove 502. The connecting part 202 abuts against the top wall of the rotating groove 502, thereby restricting the movement of the connecting part 202 along the axis of the rotating part 1. After rotating 90 degrees, the side of the connecting part 202 abuts against the first and second side walls of the rotating groove 502. The connecting part 202 is rotated into place. At this time, rotate the scraper part 201 along the axis of the connecting part 202. The scraper part 201 presses against the positioning block 505. The positioning block 505 slides into the receiving groove 503. Continue to press down the scraper part 201. When the scraper part 201... When the length direction of the material section 201 is parallel to the length direction of the straight groove 501, the positioning block 505 is inserted into the positioning groove 203 to limit the scraper section 201 in the straight groove 501. At this time, the scraper 2 and the rotating part 1 are relatively fixed, and the assembly is completed. When it is necessary to remove the scraper 2 from the chute 4, the scraper 2 is flipped so that the scraper 2 rotates around the axis of the connecting part 202. The positioning block 505 exits the positioning groove 203 so that the other end of the scraper 2 is away from the rotating part 1 and folded up (at this time, the projection of the scraper 2 on the plane where the rotating part 1 is located falls inside the rotating part 1). At this time, the rotating part 1 and the scraper 2 can pass smoothly through the through hole opened on the inner side wall of the chute 4.

[0041] After the rotating part 1 and the scraper 2 are assembled, the output shaft of the reducer 302 passes through the through hole opened on the inner wall of the chute 4 and connects to the rotating part 1. Of course, the rotating part 1 and the reducer 302 can also be connected on the outside first. After the rotating part 1 and the scraper 2 are installed in place, a baffle needs to be installed at the through hole opened on the inner wall of the chute 4 to block the gap between the through hole and the output shaft and prevent material or dust from flowing out of the through hole.

[0042] Of course, in this embodiment, the connecting component 5 can also be in other forms. The connecting component 5 includes a T-slot, which includes a first strip groove and a second strip groove that are connected. The connecting part 202 is rotatably connected to the second strip groove via a round shaft. The connecting part 202 rotates around the axis of the round shaft, causing the scraper part 201 to fold up or unfold. When unfolded, the scraper part 201 is partially located in the first strip groove. A rubber pad is connected to the inner wall of the first strip groove. When the scraper part 201 is placed in the first strip groove, it can prevent free rotation when the worker does not apply force. A screw is screwed onto the rotating part 1, and a baffle is fixed to one end of the screw. By turning the screw, the baffle blocks the first strip groove to limit the scraper 2 or moves the baffle away, allowing the scraper 2 to flip. Its purpose does not depart from the design concept of this utility model, therefore, it should fall within the protection scope of this utility model.
