Description

Technical Field

[0001] The utility model relates to the technical field of roller press feeding, in particular to an anti-jamming device for the feeding gate of a roller press. Background Art

[0002] Roller presses are widely used in industries such as mining, metallurgy, chemical engineering, and building materials. When feeding a roller press, materials are conveyed into the roller press through a feeding bin connected to the upper feeding port of the roller press. A support frame is arranged between the feeding port of the roller press and the feeding bin. A feeding gate is slidably connected to the support frame. By adjusting the opening degree of the gate, the supply speed and supply quantity of materials can be controlled, ensuring the working efficiency and product quality of the roller press. The materials processed by the roller press include coal, ore, etc.

[0003] When the gate moves in and out at the bottom of the feeding bin to achieve feeding and discharging, if the end of the gate is initially located at the lower end of the feeding bin, and at this time the forward end of the gate is not yet connected to the end of the support frame, there is no support force at the bottom of the forward end of the gate. When some heavy materials in the feeding bin fall and hit the end of the gate, the end of the gate is instantly subjected to a large acting force and is prone to deformation. On the one hand, the tightness between the gate and the bottom of the feeding bin becomes poor, and leakage of materials is likely to occur. On the other hand, after the gate is deformed, the frictional force at the connection with the support frame increases, and the gate is prone to jamming.

[0004] Therefore, we propose an anti-jamming device for the feeding gate of a roller press to solve the above problems. Content of the Utility Model

[0005] The embodiment of the utility model provides an anti-jamming device for the feeding gate of a roller press to solve the above-mentioned technical problems.

[0006] The embodiment of the utility model adopts the following technical scheme: It includes a feeding bin for feeding materials into the roller press and a gate member for blocking the outlet of the feeding bin. A support member for supporting the gate member is arranged below the feeding bin. It further includes a driving member, a baffle, and a linkage member. The driving member is arranged at one end of the support member, and the movable end of the driving member is connected to the gate member for driving the gate member to move. The baffle is movably connected in the feeding bin for intercepting some materials in the feeding bin. The linkage member is arranged on the gate member for driving the baffle to partially block the feeding bin following the movement of the gate member.

[0007] Furthermore, a receiving bin for accommodating the baffle is arranged at the lower end of the feeding bin, and the cross-sectional area of the receiving bin is larger than the cross-sectional area of the feeding bin.

[0008] Further, the linkage member includes an inclined portion and a straight portion integrally formed and connected to one end of the inclined portion. The inclined portion is located at one end of the linkage member close to the advancing direction of the gate member, and the inclined portion gradually slopes upward from the end close to the straight portion.

[0009] Further, the upper surface of the linkage member is a curved surface.

[0010] Further, a through groove for the passage of the linkage member is provided on the side wall of the accommodation bin.

[0011] Further, a marking layer is provided on the baffle. The marking layer includes a first color layer connected to the upper surface of the baffle and a second color layer covering the first color layer.

[0012] The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0013] In the present invention, when the gate member moves below the feed bin to adjust the material supply amount, it drives the linkage member to move synchronously, so that the linkage member pushes the baffle to move. When the baffle is turned to a certain angle, the gap between the inner wall of the feed bin and the baffle decreases, so that some materials with larger volumes can be intercepted in the feed bin, avoiding the direct impact of larger materials on the gate member, which may cause bending deformation of the gate member and other effects, sharing the pressure on the gate member, so that the gate member will not be deformed due to excessive pressure, and thus it is more smooth when sliding on the support member for opening and closing.

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the scope of protection of the present utility model.

[0022] The following will, with reference to the drawings, detail the technical solutions provided by the embodiments of the present utility model.

[0023] An embodiment of the present utility model provides a device for preventing jamming of the feed gate of a roller press, which includes a feed bin 1 for feeding materials into the roller press and a gate member 11 for blocking the outlet of the feed bin 1. A support member 12 for supporting the gate member 11 is provided below the feed bin 1. A driving member 2 is provided on one side of the support member 12. The driving member 2 is used to drive the gate member 11 to slide within the support member 12, and the driving member 2 is located in the middle of the gate member 11, which can drive the gate member 11 to run smoothly on the support member 12, avoiding problems such as jamming of the gate member 11 caused by inconsistent movement speeds on both sides of the gate member 11. Among them, the driving member 2 can be driven by a hydraulic cylinder or other means. The feed rate is adjusted by the overlapping area between the gate member 11 and the outlet of the feed bin 1. When the overlapping area between the two is larger, the feed rate is smaller, and vice versa. And when part of the end of the gate member 11 is located below the outlet of the feed bin 1, if some materials with a larger mass fall in the feed bin 1 and directly hit the end of the gate member 11, since the end of the gate member 11 has no support, the gate member 11 will bear a bending moment and deform, increasing the friction between the gate member 11 and the support member 12, and even causing a jamming phenomenon when the gate moves. Therefore, the present utility model will make the following improvements to the above situation. It also includes a baffle 3 and a linkage member 4. The baffle 3 is movably connected to the feed bin 1 through a connecting shaft and is used to intercept part of the materials in the feed bin 1. The linkage member 4 is provided on the gate member 11 and is used to drive the baffle 3 to partially block the feed bin 1 as it follows the movement of the gate member 11. When the gate member 11 drives the linkage member 4 to move into the feed bin 1, the linkage member 4 will contact the baffle 3, causing the baffle 3 to swing towards one side of the feed bin 1 with the rotating shaft as the center. At this time, the gap between the movable end of the baffle 3 and the inner wall of the feed bin 1 gradually decreases, so the passing efficiency of the materials in the feed bin 1 decreases. Some larger materials will be intercepted by the baffle 3 and will not directly hit the end of the gate member 11. Some smaller materials, due to their lighter mass, even if they fall on the gate member 11, will not easily cause deformation of the gate member 11, thus sharing the pressure-bearing degree of the gate member 11 and avoiding phenomena such as jamming during movement caused by the deformation and bending of the gate member 11. And the baffle 3 only plays a role in intercepting part of the materials. Therefore, even if the baffle 3 is deformed by being hit by the materials, it will not affect the interception of the materials.

[0024] Among them, a receiving bin 5 for accommodating the baffle 3 is provided at the lower end of the feed bin 1. The cross-sectional area of the receiving bin 5 is larger than that of the feed bin 1. Specifically, when the gate member 11 drives the linkage member 4 to move outside the feed bin 1, the linkage member 4 will not contact the baffle 3. Under the action of its own gravity, the baffle 3 is in a vertical state in the receiving bin 5 and is misaligned with the material input direction in the feed bin 1. When the materials enter the roller press, they will not randomly hit the baffle 3.

[0025] Preferably, a through groove 6 for the linkage member 4 to pass through is provided on the side wall of the accommodation bin 5. When the shutter member 11 moves, it can drive the linkage member 4 to pass through the through groove 6. Among them, the number of linkage members 4 can be multiple to achieve a more stable abutting force of the baffle 3, and the number of through grooves 6 corresponds to the number of linkage members 4.

[0026] Preferably, the linkage member 4 includes an inclined portion 41 and a straight portion 42 integrally formed and connected to one end of the inclined portion 41. The inclined portion 41 is located at one end of the linkage member 4 close to the advancing direction of the shutter member 11, and the inclined portion 41 gradually slopes upward from the end close to the straight portion 42. When the linkage member 4 initially abuts against the baffle 3, it contacts the baffle 3 through the inclined portion 41. As the shutter member 11 drives the linkage member 4 to continuously move below the feed bin 1 and gradually achieves the complete closure of the feed bin 1, the baffle 3 will abut against the straight portion 42. At this time, the baffle 3 will not continue to flip, and the angle between the baffle 3 and the inner wall of the accommodation bin 5 is an acute angle. The distance between the movable end of the baffle 3 and the inner side wall of the feed bin 1 will also reach a constant state, thereby realizing the interception of some materials with larger volume and mass.

[0027] Preferably, the upper surface of the linkage member 4 is a curved surface. When the material falls on the linkage member 4, due to the effect of the curved surface of the linkage member 4, it forms a point contact or line contact, with a small damage surface to the linkage member 4 and no large pothole phenomenon like a flat surface, thus prolonging the service life of the linkage member 4.

[0028] Preferably, a marking layer 7 is provided on the baffle 3. The marking layer 7 includes a first color layer 71 connected to the upper surface of the baffle 3 and a second color layer 72 covering the first color layer 71. The first color layer 71 and the second color layer 72 can be coatings of different colors, such as red and green, etc., for easy distinction. When the material falls on the baffle 3, it will first wear the outermost second color layer 72. When the second color layer 72 is worn and the first color layer 71 is exposed, it proves that the wear degree of the baffle 3 is relatively large, and operations such as disassembly and replacement can be considered.

[0029] It should be noted that the baffle 3 and the linkage member 4 can be made of the same material as the shutter member 11, such as metal, etc., to improve the service life and anti-deformation ability.
