A cleaning mechanism for slag discharge rollers

Abstract

This utility model relates to a cleaning mechanism for slag discharge rollers, including a belt conveyor, a slag discharge roller, and a conveyor belt. The belt conveyor is equipped with a cleaning structure, which includes a transmission platform fixedly installed on one side of the belt conveyor. This cleaning mechanism for slag discharge rollers utilizes the rotational power of the slag discharge roller itself to drive the cleaning mechanism, achieving synchronous and automatic cleaning. This avoids the tediousness of manual periodic cleaning, prevents impurities from entering between the conveyor belt and the slag discharge roller, and prevents belt misalignment or damage. Furthermore, the reciprocating motion design allows the cleaning components to cover the entire width of the roller, improving cleaning thoroughness. The flexible design of the rubber scraper prevents hard scraping from damaging the roller while effectively removing stubborn impurities. Users can choose between a brush roller or a rubber scraper, or a combination thereof, depending on the material characteristics to adapt to different working conditions. The cleaning mechanism is driven by the rotational force of the slag discharge roller, and energy consumption can be reduced.

Description

Technical Field

[0001] This utility model relates to the field of slag discharge roller technology, specifically a cleaning mechanism for slag discharge rollers. Background Technology

[0002] The slag discharge roller is an important component of a belt conveyor, mainly used to remove materials and impurities adhering to the conveyor belt. The slag discharge roller consists of a roller body, an internal cone, and a drive unit. The roller body adopts a cage-like structure, usually composed of multiple parallel steel bars or wires, forming a cage-like shape. The internal cone is a double-cone structure with pointed ends and a thicker middle inside the roller. When the material enters the roller through the slag discharge hole, it will move towards both ends of the roller under the guidance of the cone, and finally be discharged from the end holes to the stockpile, thus realizing the slag discharge function. The drive unit generally consists of a motor, a reducer, a coupling, etc., which provides power for the rotation of the roller, enabling the roller to rotate at a set speed and direction, ensuring the continuity and stability of the slag discharge process.

[0003] In existing technologies, slag discharge rollers use slag discharge holes and internal conical structures to promptly remove materials adhering to the return conveyor belt. However, in actual use, slag discharge rollers have poor adaptability to sticky materials. If the material is too sticky, such as wet mud or high-humidity powder, it easily adheres to the surface of the slag discharge roller, leading to a decrease in slag discharge efficiency. Moreover, the adhered material can squeeze the conveyor belt, causing it to shift or be damaged, thus affecting the normal operation of the equipment. Therefore, a cleaning mechanism for slag discharge rollers is proposed to solve the above problems. Utility Model Content

It has the advantage of easily cleaning materials adhering to the slag discharge rollers, solving the problem that in actual use, slag discharge rollers have poor adaptability to sticky materials. If the material is too sticky, such as wet mud or high-humidity powder, it is easy to stick to the surface of the slag discharge rollers, resulting in a decrease in slag discharge efficiency. Moreover, the sticky material will squeeze the conveyor belt, causing the conveyor belt to break or be damaged, thus affecting the normal use of the equipment.

The rubber scrapers are fixedly installed on the cleaning component and have a concave arc surface on one side.

[0009] Furthermore, a connecting column is fixedly installed on the turntable, one end of the connecting column penetrates through the connecting frame, and the outer surface of the connecting column is connected to the inner wall of the connecting frame.

[0010] Furthermore, the guide bracket consists of a connecting rod and two guide rods, which are fixedly connected to the connecting frame and slidably connected to the belt conveyor.

[0011] Furthermore, the transmission component includes a belt and two pulleys, with the two pulleys fixedly mounted on the output shaft of the asynchronous motor and the brush roller, respectively, and the belt mounted on the two pulleys.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figure 1-4 A cleaning mechanism for a slag discharge roller in this embodiment includes a belt conveyor 1, a slag discharge roller 2 and a conveyor belt 3, and a cleaning structure 4 is provided on the belt conveyor 1.

[0021] Example 2: Please refer to Figure 1-4 Based on Embodiment 1, the cleaning structure 4 includes a transmission platform 41 fixedly installed on one side of the belt conveyor 1. A transmission shaft 42 with one end extending through and to the outside is rotatably installed inside the transmission platform 41. A turntable 43 is fixedly installed at one end of the transmission shaft 42. Meshing bevel gears 44 are fixedly installed on both the transmission shaft 42 and the slag discharge roller 2. A connecting frame 45 is slidably installed on the turntable 43. A guide bracket 46 that extends through the belt conveyor 1 is fixedly connected to one side of the connecting frame 45. A cleaning component 47 for cleaning the material adhering to the surface of the slag discharge roller 2 is provided at one end of the guide bracket 46.

[0022] A connecting column 431 is fixedly installed on the turntable 43. One end of the connecting column 431 passes through the connecting frame 45. The outer surface of the connecting column 431 is connected to the inner wall of the connecting frame 45. The connecting frame 45 on the turntable 43 converts the circular motion into linear motion, driving the guide bracket 46 to slide back and forth along the belt conveyor 1.

[0023] In addition, the guide bracket 46 consists of a connecting rod and two guide rods. The connecting rod and the two guide rods are fixedly connected to the connecting frame 45, and the connecting rod and the two guide rods are slidably connected to the belt conveyor 1. The double guide rod structure ensures that the cleaning component 47 moves smoothly and avoids uneven cleaning or equipment damage caused by shaking.

[0024] Using the above technical solution, the slag discharge roller 2 rotates and drives the bevel gear 44 to rotate. Since the two bevel gears 44 mesh, they control the rotation of the transmission shaft 42 on the transmission table 41, thereby transmitting the rotational force of the slag discharge roller 2 to the cleaning structure 4. The transmission shaft 42 drives the turntable 43 to rotate, and the connecting frame 45 on the turntable 43 converts the circular motion into linear motion, driving the guide bracket 46 to slide back and forth along the belt conveyor 1. The back and forth motion of the guide bracket 46 drives the cleaning component 47 to move laterally on the surface of the slag discharge roller 2, thereby achieving all-round cleaning.

[0025] Example 3: Please refer to Figure 1-4 Based on Embodiment 2, a connector 471 fixedly connected to one end of the guide bracket 46 is installed inside the cleaning component 47. A brush roller 472 is rotatably mounted on the cleaning component 47. A cleaning plate 473 for cleaning the material attached to the brush roller 472 is fixedly mounted on the cleaning component 47. An asynchronous motor 474 is fixedly mounted on the cleaning component 47. A transmission component 475 for driving the brush roller 472 to rotate is provided on the output shaft of the asynchronous motor 474.

[0026] One embodiment of the cleaning component 47 includes a connector 471 and several rubber scrapers 476. The connector 471 is fixedly installed on the cleaning component 47 and fixedly connected to the guide bracket 46. The rubber scrapers 476 are fixedly installed on the cleaning component 47 and have a concave arc surface on one side. The flexible design of the rubber scrapers 476 avoids hard scraping and damage to the roller, while effectively removing stubborn impurities. The arc surface design fits the roller surface and scrapes away stubborn adhering substances during reciprocating movement. It is suitable for wet mud and clump materials.

[0027] In addition, the transmission component 475 includes a belt and two pulleys. The two pulleys are fixedly mounted on the output shaft of the asynchronous motor 474 and the brush roller 472, respectively. The belt is mounted on the two pulleys. The asynchronous motor 474 drives the output shaft to rotate, and the belt and pulleys drive the brush roller 472 to rotate. The brush roller 472 rotates at high speed to brush away the sticky material on the surface of the slag discharge roller 2.

[0028] Using the above technical solution, when the cleaning component 47 is selected as the brush roller 472, the asynchronous motor 474 drives the brush roller 472 to rotate at high speed through the transmission component 475 to brush away the sticky material on the roller surface, which is suitable for powder and granular impurities. When the cleaning component 47 is selected as the rubber scraper 476, the arc surface design of the rubber scraper 476 fits the roller surface and scrapes away stubborn adhesives in reciprocating movement, so that a suitable cleaning method can be selected according to the needs.

[0029] The working principle of the above embodiments is as follows:

[0030] In use, the cleaning mechanism for the slag discharge roller 2 rotates and drives the bevel gear 44 to rotate. Since the two bevel gears 44 mesh, the transmission shaft 42 on the transmission table 41 is controlled to rotate, thereby transmitting the rotational force of the slag discharge roller 2 to the cleaning structure 4.

[0031] The drive shaft 42 drives the turntable 43 to rotate. The connecting frame 45 on the turntable 43 converts the circular motion into linear motion, driving the guide bracket 46 to slide back and forth along the belt conveyor 1. The reciprocating motion of the guide bracket 46 drives the cleaning component 47 to move laterally on the surface of the slag discharge roller 2, achieving all-round cleaning.

[0032] When the cleaning component 47 selects the brush roller 472, the asynchronous motor 474 drives the brush roller 472 to rotate at high speed through the transmission component 475, brushing away the sticky material on the roller surface. This is suitable for powder and granular impurities. When the cleaning component 47 selects the rubber scraper 476, the arc design of the rubber scraper 476 fits the roller surface and scrapes away stubborn adhesives in reciprocating movement. Thus, a suitable cleaning method can be selected according to the requirements.
