Description

Technical Field

[0001] This utility model belongs to the field of continuous hydrogen crushing furnace technology, specifically, it relates to a protective device for the feeding hopper of a continuous hydrogen crushing furnace. Background Technology

[0002] During the operation of the continuous hydrogen crushing furnace, the feeding hopper plays a crucial role in accurately feeding the material to be processed into the furnace.

[0003] Utility model CN222892494U relates to a protective device for a continuous hydrogen crushing furnace charging hopper, comprising a hopper body, a charging trough for loading NdFeB at the top of the hopper body, a guide portion protruding from one side of the top of the hopper body, and anti-detachment portions formed by folded edges on both sides of the guide portion. A baffle plate is provided at the opening of the charging trough, and an anti-collision pad is fixedly connected to the bottom of the baffle plate. The side of the baffle plate away from the guide portion is connected to the hopper body through a resistance mechanism. This utility model relates to the field of charging hopper technology. This protective device for a continuous hydrogen crushing furnace charging hopper, through the baffle plate, can block the opening of the charging trough, so that the charging trough will not leak even when full of material, thereby increasing the safety of the charging hopper. At the same time, the baffle plate can also restrict the dumping of material to prevent spillage during dumping, reducing the difficulty of subsequent cleaning.

[0004] However, the aforementioned patent still has the following problems: the material continuously impacts the inner wall of the feeding hopper during the feeding process. Although existing technologies use a wear-resistant coating on the inner wall of the feeding hopper to resist the impact and wear of the material, in actual production, due to the frequent and forceful impacts, the service life of the wear-resistant coating is short. As the wear-resistant coating gradually wears away, the inner wall of the feeding hopper will be exposed, and the material will directly contact and impact the inner wall, which will not only accelerate the damage to the inner wall of the feeding hopper, but also generate more material debris. This debris mixed into the material to be processed will affect the hydrogen crushing effect of the material, and the continuous material impact will have an adverse effect on the fixation effect of the feeding hopper.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0040] Working principle: The first guide plate 22, the second guide plate 23, and the third guide plate 24 are fixedly installed on the inner wall of the conical feeding hopper 10, and are arranged sequentially from top to bottom at a 15-degree inclination angle. After the material enters the feeding hopper 10, it slides down the inclined surfaces of these guide plates in sequence under its own gravity, achieving orderly feeding. At the same time, the wear-resistant coating 25 applied to the top of these three sets of guide plates can effectively resist the wear during the material's descent, extending the service life of the guide plates. The fourth guide plate 26 is fixedly installed on the inner wall of the feeding hopper 10, and its eight sets of guide holes 27 can divide the material that slides down to this point for separate feeding, so that the material enters the next stage more evenly and dispersedly, avoiding material accumulation and improving feeding efficiency. The guide pipe 28 at the bottom of the feeding hopper 10 guides the material through the channel into the continuous hydrogen crushing furnace. A feeding hopper top cover 11 is provided on the top of the feeding hopper 10. A first fixing rod 17 is fixed in the first arc-shaped fixing plate 16 on one side of the outer wall of the feeding hopper top cover 11, and a second fixing rod 19 is fixed in the second arc-shaped fixing plate 18 on one side of the outer wall of the feeding hopper 10. A set of first fixing sleeves 21 are installed at both ends of the two sets of first fixing plates 20 outside the feeding hopper 10. The second fixing rod 19 is fixed inside the first fixing sleeve 21, and the first fixing rod 17 is rotatably installed inside the other set of first fixing sleeves 21. When it is necessary to open the feeding hopper top cover 11, the feeding hopper top cover 11 is pushed, which drives the first fixing rod 17 to rotate inside the first fixing sleeve 21, so that the feeding hopper top cover 11 rotates around the first fixing rod 17 as the axis, thereby realizing the separation of the feeding hopper 10 and the feeding hopper top cover 11, which facilitates the addition of materials into the feeding hopper 10. After adding materials, the top cover 11 of the feeding hopper can be closed by reversing the operation. The top of the feeding hopper 10 is fixed with a first snap-fit ​​ring plate 12, and the bottom of the top cover 11 of the feeding hopper has a first snap-fit ​​ring groove 13. The first snap-fit ​​ring plate 12 is snapped into the inside of the first snap-fit ​​ring groove 13. The bottom of the top cover 11 of the feeding hopper is fixed with a first annular sealing strip 14. When the top cover 11 of the feeding hopper is closed, the first snap-fit ​​ring plate 12 snaps into the first snap-fit ​​ring groove 13, so that the outer wall of the first annular sealing strip 14 is tightly attached to the inner wall of the feeding hopper 10, effectively preventing the material from leaking from the top of the feeding hopper 10 during the conveying process and ensuring the normal operation of the equipment. The outside of the feeding hopper 10 is provided with a first arc-shaped limiting plate 29 and a second arc-shaped limiting plate 30, and nine sets of third fixing rods 31 are fixed between the two. A first rubber ring plate 32 is attached to the inner wall of the first arc-shaped limiting plate 29, a second rubber ring plate 33 is attached to the inner wall of the second arc-shaped limiting plate 30, and a third rubber ring plate 34 is fixed to the top of the second rubber ring plate 33. The feeding hopper 10 is placed inside the first arc-shaped limiting plate 29 and the second arc-shaped limiting plate 30, so that the inner wall of the first rubber ring plate 32 is in close contact with the outside of the feeding hopper 10, the inner wall of the second rubber ring plate 33 is in close contact with the outer wall of the guide pipe 28, and the inner wall of the third rubber ring plate 34 is in close contact with the outer wall of the feeding hopper 10.The elasticity of the rubber ring plate can buffer and fix the hopper 10, preventing it from shaking or shifting during operation. It also provides some protection for the hopper 10 and the guide pipe 28, reducing damage from external factors. A handle 15 is fixedly installed on the top of the hopper top cover 11. When it is necessary to open or close the hopper top cover 11, the operator can hold the handle 15 and apply pulling or pushing force to pull the hopper top cover 11 more conveniently and effortlessly, thus realizing the opening and closing operation.
