Description

Technical Field

[0001] This utility model relates to the field of sintering flux production technology, and in particular to a material blocking and scraping structure for a belt conveyor. Background Technology

[0002] Sintered flux, as an important auxiliary material in the welding process, requires the raw material to be processed into granular products using a disc granulator during its production. To ensure the smooth operation of subsequent processes, the granulated flux particles need to be conveyed to a rotary dryer for drying.

[0003] Currently, the industry commonly uses inclined belt conveyors to complete this conveying process. Flux granules fall directly from the discharge port of the disc granulator onto the inclined conveyor belt, and the movement of the belt transports the material upwards (towards the dryer). However, this traditional solution has a significant drawback: because the conveyor belt is inclined, the flux granules are prone to rolling down the inclined surface of the belt under the influence of gravity during the conveying process, resulting in some material loss.

[0004] To address this issue, the existing method typically involves placing a collection box on the lowest side of the belt conveyor (the end closest to the ground) to catch the falling flux particles. Workers then periodically use shovels and other tools to scoop the material back onto the conveyor belt. However, this method has several drawbacks: firstly, frequent manual operation increases labor costs; secondly, the collected flux particles, due to insufficient drying time, retain a certain degree of moisture and are prone to clumping if stored in the collection box for extended periods. This not only affects subsequent drying efficiency but may also reduce the overall quality by allowing clumped particles to mix with qualified products.

[0005] In summary, existing inclined belt conveyors for conveying sintered flux particles suffer from significant material roll-off losses, frequent manual intervention, and a high risk of wet material agglomeration. A more efficient and stable conveying structure is urgently needed to optimize the production process. Summary of the Invention

[0006] This utility model addresses the shortcomings of existing technologies by providing a material blocking and scraping structure for belt conveyors.

[0007] This utility model is achieved through the following technical solution: a material blocking and scraping structure for a belt conveyor, comprising a first belt conveyor for receiving material falling from the discharge port of a disc granulator and being inclined, and a second belt conveyor installed at the end of the first belt conveyor near the ground. The first belt conveyor includes a first frame, and the second belt conveyor includes a second frame, with an angle of less than 90 degrees between the first frame and the second frame. An electric roller and a first driven roller are respectively installed at both ends of the first frame, and a second driven roller is installed at the upper end of the second frame. A deflector roller is provided at the angle between the first frame and the second frame. The electric roller, the first driven roller, the second driven roller, and the deflector roller cooperate to realize the conveyor belt drive. A baffle plate is installed in the angled area between the first frame and the second frame, with the lower end of the baffle plate contacting the conveyor belt on the upper side of the first frame and the upper end of the baffle plate contacting the conveyor belt on the left side of the second frame.

[0008] Preferably, the steering roller is a bidirectional spiral steering roller. The bidirectional spiral steering roller adopts an existing structure. The bidirectional spiral steering roller can automatically separate the material at the included angle when rotating by the left and right thread design on the roller surface.

[0009] Preferably, mounting plates are fixed on the front and rear sides of the first frame, and the two ends of the bidirectional spiral steering roller are rotatably connected to the two mounting plates respectively.

[0010] Preferably, a mounting mechanism for installing the baffle plate is provided on the first frame and the second frame. The mounting mechanism includes two connecting plates, which are respectively located on the front and rear sides of the first frame. One end of each connecting plate is connected to the first frame, and the other end is connected to the second frame. A fixing rod is fixed to each of the front and rear ends of the baffle plate, passing through the two connecting plates respectively. Two fixing nuts are threaded onto each fixing rod, located on both sides of the connecting plate. By adjusting the position of the two fixing nuts, the position of the baffle plate can be adjusted, ensuring effective contact between the baffle plate and the conveyor belt, thereby ensuring the material blocking and scraping effects.

[0011] Preferably, the connecting plate is fixedly connected to both the first frame and the second frame using bolts.

[0012] Preferably, the mounting plate is fixedly connected to the first frame with bolts.

[0013] Preferably, the angle between the first frame and the second frame is 60 degrees.

[0014] Preferably, to prevent material from falling off the sides during conveying, side baffles are installed on both the front and rear sides of the first frame.

[0015] The beneficial effects of this utility model are as follows: 1. By combining the first belt conveyor and the second belt conveyor, an upward-curving structure is formed at the end (i.e., the end of the belt bends upward to form an angle), which blocks particles that might otherwise roll downward within the angle area; together with the baffle plate installed in the angle area, it can effectively prevent particles from sliding down the inclined surface of the belt.

[0016] The integrity rate of material conveying is greatly improved, eliminating the need for collection boxes and manual recycling, and significantly reducing material loss.

[0017] 2. In addition to blocking particles, the baffle plate can also be used as a scraper: when the belt runs past the upper part of the baffle plate, the upper part of the baffle plate contacts the surface of the belt, which can scrape off the flux particles adhering to the belt and let them enter the dryer together with the main conveyed material.

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0020] like Figure 1-2 As shown, this utility model includes a first belt conveyor for receiving material falling from the discharge port 1 of a disc granulator and is inclined. A second belt conveyor is installed at the end of the first belt conveyor near the ground. The first belt conveyor includes a first frame 4, and the second belt conveyor includes a second frame 8. The first frame 4 and the second frame 8 form an angle of less than 90 degrees. An electric roller 14 and a first driven roller 11 are respectively installed at both ends of the first frame 4. A second driven roller 12 is installed at the upper end of the second frame 8. A deflector roller 10 is provided at the angle between the first frame 4 and the second frame 8. The electric roller 14, the first driven roller 11, the second driven roller 12, and the deflector roller 10 cooperate to realize the transmission of the conveyor belt 3. A baffle plate 5 is installed in the angled area between the first frame 4 and the second frame 8. The lower end of the baffle plate 5 contacts the conveyor belt 3 on the upper side of the first frame 4, and the upper end of the baffle plate 5 contacts the conveyor belt 3 on the left side of the second frame 8.

[0021] In this embodiment, the steering roller 10 is a bidirectional spiral steering roller. The bidirectional spiral steering roller adopts an existing structure. Through the left and right thread design on the roller surface, the bidirectional spiral steering roller can automatically separate the material at the included angle during rotation. Mounting plates 9 are fixed on the front and rear sides of the first frame 4, respectively, and the two ends of the bidirectional spiral steering roller are rotatably connected to the two mounting plates 9.

[0022] In this embodiment, a mounting mechanism for mounting the baffle plate 5 is provided on the first frame 4 and the second frame 8. The mounting mechanism includes two connecting plates 7, which are respectively located on the front and rear sides of the first frame 4. One end of each connecting plate 7 is connected to the first frame 4, and the other end is connected to the second frame 8. A fixing rod 6 is fixed to each of the front and rear ends of the baffle plate 5, and the two fixing rods 6 pass through the front and rear connecting plates 7 respectively. Two fixing nuts 13 are threaded onto each fixing rod 6, and the two fixing nuts 13 are located on both sides of the connecting plate 7. By adjusting the position of the two fixing nuts 13, the position of the baffle plate 5 can be adjusted so that the baffle plate 5 effectively contacts the conveyor belt 3, thereby ensuring the material blocking and scraping effect.

[0023] In this embodiment, the connecting plate 7 is fixedly connected to the first frame 4 and the second frame 8 by bolts.

[0024] In this embodiment, the mounting plate 9 and the first frame 4 are fixedly connected by bolts.

[0025] In this embodiment, the included angle between the first frame 4 and the second frame 8 is 60 degrees.

[0026] In this embodiment, to prevent material from falling off the sides during conveying, side baffles 2 are installed on both the front and rear sides of the first frame 4.

[0027] In practical use, the material from the discharge port 1 of the disc granulator falls directly onto the corresponding conveyor belt 3 of the first belt conveyor. The movement of the belt propels the material towards the dryer. The combined design of the first and second belt conveyors creates an upward-curving end structure (i.e., the belt end bends upward to form an angle), blocking particles that might otherwise roll downwards within the angled area. Combined with the baffle plate 5 installed in the angled area, this effectively prevents particles from sliding down the inclined surface of the belt. In addition to blocking particles, the baffle plate 5 can also be used as a scraper: when the belt passes over the upper end of the baffle plate 5, the upper end of the baffle plate 5 contacts the belt surface, scraping off flux particles adhering to the belt and allowing them to enter the dryer along with the main conveyed material.
