Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chrome corundum processing, and particularly relates to a raw material crushing auxiliary platform for chrome corundum production. Background Art
[0002] Chrome corundum is a refractory material primarily composed of aluminum oxide and a certain proportion of chromium oxide. Initially, the raw chromium oxide is in the form of large, hard blocks that require gradual crushing to form a powder. However, after the product is fused and discharged from the electric arc furnace, it is too large to be crushed in a crusher. Therefore, conventional methods typically place the blocks on a platform on the workshop floor and use equipment such as hammers to initially crush the blocks.
[0003] The Chinese utility model patent application number CN202320474409.1 discloses a reversible platform for crushing molten chromium blocks, comprising a reversible base plate, the upper surface of which is provided with two symmetrical movable baffles, the movable baffles being in an upright position, one end of the lower surface of the movable baffle being rotatably connected to the base plate via a pin, and a plug sleeve being fixed to the side position of the other end of the movable baffle, the center line of the plug sleeve being perpendicular to the upper surface of the base plate, a plug rod being slidably installed at the center hole of the plug sleeve, the plug rod being able to be inserted into positioning holes provided at different positions on the surface of the base plate, thereby achieving adjustment of the angle of the movable baffle. The purpose of this solution is to design the traditional platform into a reversible structure, so that after the material block is crushed, one end of the platform can be lifted to tilt the platform, so that the material block can quickly enter the discharge channel, thereby reducing the workload of workers, improving work efficiency, and reducing the adverse effects of dust on workers' health.
[0004] However, in the actual process of crushing the molten chromium blocks, there are still certain defects. On the one hand, since the blocks are placed on the platform, when the blocks are crushed by using a breaker hammer or a crushing cone, the blocks are easy to move on the platform, which makes the crushing difficult. On the other hand, after the blocks are crushed, there are more and more blocks on the surface of the platform, and some large blocks are not easy to check, so there is a problem of missing blocks due to unbroken blocks. On the other hand, after the crushing is completed, one end of the platform needs to be lifted, which is also time-consuming and labor-intensive. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a raw material crushing auxiliary platform for chrome corundum production, which can be provided with a feeding hole in the middle position of the surface of the platform to facilitate the falling of small material blocks, so that during the crushing process, some small-sized material blocks can fall downward from the feeding hole, avoiding accumulation on the platform and causing visual interference, and also avoiding the need to lift one end of the platform later. In addition, in the middle position of the platform, a raised partition is used to limit the material blocks to a certain extent, avoiding the problem of material block displacement during the crushing process, and improving the crushing rate.
[0006] The technical solution adopted by the utility model is: a raw material crushing auxiliary platform for chrome corundum production, including a platform body, the surface of the platform body has a downwardly concave area, and the concave depth of the concave area is gradually increased from the outside of the platform body to the inside, a through hole is provided in the middle position of the concave area, and a plurality of partitions intersecting horizontally and vertically are provided inside the through hole, and the plurality of partitions divide the through hole into a plurality of feeding holes, and the upper surface of the partition is higher than the lowest point of the concave area.
[0007] The through hole is a rectangular hole or a circular hole.
[0008] The cross section of the concave area is V-shaped, and the angle thereof is 165°-175°.
[0009] Baffles are detachably installed around the platform body.
[0010] Insertion rods are installed at both ends of the lower surface of the baffle, and mounting holes matching the insertion rods are opened at the edges of the platform body, and the insertion rods can be inserted into the mounting holes.
[0011] A plurality of springs are installed below the platform body.
[0012] The beneficial effects of the utility model are:
[0013] The utility model has a reasonable design structure and can set a feeding hole in the middle position of the surface of the platform to facilitate the falling of small blocks of material, so that during the crushing process, some small-sized blocks of material can fall downward from the feeding hole, avoiding accumulation on the platform and causing visual interference, and also avoiding the need to lift one end of the platform later. In addition, in the middle position of the platform, a raised partition is used to limit the blocks of material to a certain extent, avoiding the problem of displacement of the blocks of material during the crushing process and improving the crushing rate.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] As shown in the figure, a raw material crushing auxiliary platform for chrome corundum production includes a platform body 1. The platform body 1 is a rectangular plate structure. The surface of the platform body 1 has a downwardly concave area 2, and the concave depth of the concave area 2 is gradually increased from the outside of the platform body 1 to the inside. The purpose of setting the concave area 2 is to allow some small particles with lighter weight to be concentrated toward the center of the concave area 2 during the crushing process. A through hole 3 is opened in the middle position of the concave area 2, and a plurality of partitions 4 are provided inside the through hole 3, which intersect horizontally and vertically. The plurality of partitions 4 divide the through hole 3 into a plurality of discharge holes 5, so that the small particles can fall from the discharge holes 5 into the hopper 10 below, avoiding the problem of accumulation on the surface of the platform body 1, so that it is convenient for the staff to observe other large material blocks on the platform surface. The upper surface of the partition 4 is higher than the lowest point of the concave area 2. Such a setting can facilitate the material block to be at the position where the partition 4 is located. The partition 4 plays a certain blocking role on the material block, so as to avoid the problem of movement of the material block during crushing and improve the crushing efficiency.
[0019] In this example, the through hole 3 is a rectangular hole or a circular hole, and can also be designed as an elliptical hole, a regular polygonal hole, etc. according to actual needs.
[0020] The cross section of the concave area 2 is V-shaped with an angle of 165°-175°, which can allow some small blocks to overcome the friction between themselves and the surface of the platform body 1 under the action of their own gravity and move toward the center of the platform body 1.
[0021] Baffles 6 are detachably installed around the platform body 1 to prevent material blocks from splashing to the outside of the platform body 1 when the breaker hammer or breaker cone is crushing, thereby improving safety. Specifically, plug rods 8 are installed at both ends of the lower surface of the baffle 6, and mounting holes 7 matching the plug rods 8 are opened at the edges of the four sides of the platform body 1. The plug rods 8 can be inserted into the mounting holes 7, which has the advantage of convenient disassembly and assembly.
[0022] A plurality of springs 9 are installed below the platform body 1. In this example, the springs 9 are distributed at the four corners below the platform body 1. The purpose of providing the springs 9 is to allow the entire platform body 1 to have a small up and down swing during the crushing process of the material blocks, so as to speed up the movement of the small material blocks toward the lower material hole 5.
[0023] This raw material crushing auxiliary platform for chrome corundum production is primarily used to crush fused chromium oxide blocks. It is located above a hopper 10, the end of which is connected to a crusher (e.g., a jaw crusher, a roller crusher, etc.). During crushing, the blocks are placed on the surface of the platform body 1, and workers can use a breaker hammer or crushing cone to crush the blocks. Small blocks generated by crushing can be concentrated and moved toward the center of the inner concave area 2, eventually passing through the discharge hole 5 and falling into the hopper 10 below. Some large blocks continue to be crushed, and these large blocks can contact the edge of the partition 4, thereby avoiding the problem of displacement during crushing. Furthermore, during the crushing process, the breaker hammer or crushing cone applies force to the blocks, which in turn applies force to the platform body 1, causing the entire platform body 1 to have a slight shaking characteristic, further accelerating the removal of small blocks and improving work efficiency.
[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
