Description

Technical Field

[0001] This utility model relates to a device for preventing material accumulation on the surface roller, belonging to the technical field of sintering machine equipment in the metallurgical industry. Background Technology

[0002] A surface-enlarging roller is a type of drive roller in a belt conveyor, primarily used to increase the load-bearing area during material transport, reducing material accumulation and spillage, thereby improving transport efficiency. In existing technology, a solid floor slab is installed beneath the surface-enlarging roller. During material transport in the raw material workshops of steel companies, severe material carryover from the belt during return trips frequently occurs, accumulating on the floor slab in front of the surface-enlarging roller, piling up higher and higher, sometimes even burying the roller. This not only makes cleaning difficult but also causes environmental pollution and increases the labor intensity for workers. Utility Model Content

[0003] The purpose of this invention is to provide a device to prevent material accumulation on the dough roller, avoid the situation where the conveyor belt carries material back and accumulates material in front of the dough roller, reduce the labor intensity of workers, reduce environmental pollution, and solve the problems existing in the background technology.

[0004] The technical solution of this utility model is: A device for preventing material accumulation on a dough roller includes a belt, a dough roller, a drive roller, and a secondary chute. The dough roller and the drive roller are mounted on a head frame, which is mounted on a load-bearing beam. The dough roller and the drive roller are connected by a belt that wraps around the drive roller, with the bottom surface of the dough roller in contact with the belt. The dough roller and the drive roller rotate in opposite directions. A secondary chute is located below the dough roller and is connected to the load-bearing beam via an upper fixing plate. Material channels connected to the secondary chute are located on both sides of the dough roller. The secondary chute includes a lower web, side plates, and an upper web. The lower and upper webs are arranged at an inclination and connected by two side plates to form a cylindrical structure. The upper and lower ends of the cylindrical structure are a feed inlet and a discharge outlet, respectively. The feed inlet is located directly below the dough roller, and a conveyor belt is located below the discharge outlet. Material carried by the belt during its return stroke enters the cylindrical structure through the feed inlet via the material channel and then falls onto the conveyor belt through the discharge outlet, thus being conveyed.

[0005] The upper fixing plate of the auxiliary chute is a ring structure, consisting of two steel plates and two steel plates. The two steel plates are connected to the two side plates respectively, and the two steel plates are connected to the lower web plate and the upper web plate respectively.

[0006] The load-bearing beam has a frame structure, and the gap between the surface roller and the load-bearing beam corresponds to form a material channel.

[0007] The lower web and the upper web have different inclination angles, and the angle between the lower web and the upper fixed plate of the secondary chute is greater than the angle between the upper web and the upper fixed plate of the secondary chute.

[0008] The cross-section of the secondary chute is rectangular.

[0009] The height of the top of the drive roller is greater than the height of the top of the flour-enhancing roller, and the height of the top of the flour-enhancing roller is greater than the height of the bottom of the drive roller.

[0010] The drive roller is installed inside the main chute, which is fixedly connected to the load-bearing beam. The outlet of the main chute corresponds to the conveyor belt.

[0011] The upper fixing plate of the secondary chute is a one-piece molded structure.

[0012] This utility model uses a frame structure load-bearing beam to replace the original solid floor slab. The gap between the increasing roller and the load-bearing beam corresponds to the material channel formed on the front and rear sides of the increasing roller. The material carried by the belt return will fall into the secondary chute through the gap of the load-bearing beam, preventing the material from accumulating in front of the increasing roller at the machine head.

[0013] The working principle of this utility model is as follows: When the drive roller is running clockwise, most of the material will fall into the main chute and then onto the conveyor belt through the main chute outlet; some sticky material will stick to the belt. When returning and passing the reinforcing roller, due to the combined effects of friction and centrifugal force, the material will fall into the secondary chute. When the material passes the lower web plate, it continues to slide down and falls onto the conveyor belt under the gathering effect of the upper web plate and the two side plates, thus being conveyed.

[0014] The beneficial effects of this utility model are: preventing materials from scattering and accumulating in front of the machine head roller, reducing environmental pollution, reducing the labor intensity of workers, and having a simple structure and low cost. Attached Figure Description

The dough-forming roller 3 and the drive roller 8 are arranged front and rear on a headstock frame 7, which is mounted on a load-bearing beam 10. The dough-forming roller 3 and the drive roller 8 are connected by the belt 2, which wraps around the drive roller 8. The bottom surface of the dough-forming roller 3 is in contact with the belt 2, and the rotation directions of the dough-forming roller 3 and the drive roller 8 are opposite. A secondary chute is provided below the dough-forming roller 3, and the secondary chute is connected to the load-bearing beam 10 through an upper fixing plate 9. Next, the front and rear sides of the increasing roller 3 are provided with material channels connected to the secondary chute; the secondary chute includes a lower web plate 1, a side plate 4 and an upper web plate 5. The lower web plate 1 and the upper web plate 5 are arranged at an inclination and connected by two side plates 4 to form a cylindrical structure. The upper and lower ends of the cylindrical structure are the inlet and the outlet, respectively; the inlet is located directly below the increasing roller 3, and a conveyor belt 11 is located below the outlet; the material carried by the belt during the return trip enters the cylindrical structure through the material channel via the inlet, and then falls onto the conveyor belt 11 through the outlet, thereby being conveyed.

[0018] The upper fixing plate 9 of the auxiliary chute is a ring structure, consisting of two steel plates 91 and two steel plates 92. The two steel plates 91 are connected to the two side plates 4 respectively, and the two steel plates 92 are connected to the lower web plate 1 and the upper web plate 5 respectively.

[0019] The load-bearing beam 10 has a frame structure, and the gap between the surface roller 3 and the load-bearing beam 10 corresponds to form a material channel.

[0020] The lower web plate 1 and the upper web plate 5 have different inclination angles, and the angle between the lower web plate 1 and the upper fixing plate 9 of the secondary chute is greater than the angle between the upper web plate 5 and the upper fixing plate 9 of the secondary chute.

[0021] The cross-section of the secondary chute is rectangular.

[0022] The height of the top of the drive roller 8 is greater than the height of the top of the face-enhancing roller 3, and the height of the top of the face-enhancing roller 3 is greater than the height of the bottom of the drive roller 8.

[0023] The drive roller 8 is installed inside the main chute 6, which is fixedly connected to the load-bearing beam 10. The outlet of the main chute 6 corresponds to the conveyor belt 11.

[0024] The upper fixing plate 9 of the secondary chute is a one-piece molded structure.

[0025] This utility model uses a frame structure load-bearing beam to replace the original solid floor slab. The gap between the increasing roller 3 and the load-bearing beam corresponds to the material channel formed on the front and rear sides of the increasing roller 3. The material carried by the belt return will fall into the secondary chute through the gap of the load-bearing beam to prevent the material from accumulating in front of the increasing roller at the machine head.

[0026] The working principle of this utility model is as follows: When the drive roller 8 is running clockwise, most of the material will fall into the main chute 6 and then onto the conveyor belt 11 through the main chute outlet; some sticky material will stick to the belt 2. When returning and passing the reinforcing roller 3, due to the combined action of friction and centrifugal force, the material will fall into the secondary chute.
