Description

Technical Field

[0001] This utility model belongs to the field of covering agent feeding technology, specifically a high-alkalinity covering agent feeding device. Background Technology

[0002] In industrial metallurgical processes, it is usually necessary to add a covering agent. A high-alkalinity covering agent can form a continuous and dense covering layer on the surface of molten metal. This covering layer can effectively isolate air and prevent further oxidation of the metal. This not only maintains the purity of the metal, but also reduces metal loss caused by oxidation. Currently, in order to prevent operators from being affected by high temperatures, a feeding device is usually used to add the high-alkalinity covering agent.

[0003] Utility model patent application publication number 202223549973.X discloses an ultra-thin intermediate bag covering agent feeding device, including a box body. A filter plate is connected to the inner wall of the box body, a first bearing is embedded in the inner top wall of the box body, and a second bearing is embedded in the upper surface of the filter plate. The inner rings of the first and second bearings are connected to a connecting shaft, and a set of connecting rods are connected to the outer surface of the connecting shaft. This ultra-thin intermediate bag covering agent feeding device, through a drive motor, can drive two grinding wheels in cooperation with the connecting shaft and multiple bearings to grind the covering agent on the filter plate, crushing larger particles in the covering agent, making the covering agent finer and more usable. Multiple scrapers on the outer surface of the connecting shaft can brush off the covering agent adhering to the grinding wheels, thereby improving the grinding efficiency of the grinding wheels. The contact between the scrapers and the filter plate effectively prevents the filter plate from clogging.

[0004] As can be seen from the aforementioned patent, while there is a high-alkalinity covering agent feeding device, it still has drawbacks in actual use. The most obvious drawback is that after the covering agent is ground and crushed, it will accumulate in the feeding box. If the covering agent is not transported for a long time, it is easy for it to accumulate and clump. The clumped covering agent may not be evenly distributed in the production materials after feeding, resulting in local performance differences in the product and affecting the overall quality. Therefore, we propose a high-alkalinity covering agent feeding device. Utility Model Content

[0005] The purpose of this invention is to provide a high-alkalinity covering agent feeding device to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] This application specifically describes a high-alkalinity covering agent feeding device, comprising: a feeding box, a conveying cylinder, and a baffle. The conveying cylinder is fixedly connected to the bottom of the inner cavity of the feeding box, and the baffle is slidably disposed on the top of the conveying cylinder. A first pressing roller and a second pressing roller are rotatably connected to the upper two ends of the inner side wall of the feeding box, respectively.

[0008] A movable plate is fixedly connected to one end of the baffle, and a through hole is opened at one end of the movable plate. A limit rod is slidably connected to the inner cavity of the through hole. An elastic element for applying downward pressure to the limit rod is provided on the limit rod. A positioning plate is fixedly connected to one side wall of the conveying cylinder.

[0009] As a preferred technical solution of this application, the top of the feeding box is fixedly connected to a feeding hopper for easy feeding of the covering agent, and the two ends of the inner cavity of the feeding box are fixedly provided with guide plates for guiding the covering agent.

[0010] As a preferred technical solution of this application, the transmission component includes two sets of synchronizing rods and two sets of synchronizing gears. The two sets of synchronizing rods are respectively fixedly connected to one end of the first rolling roller and one end of the second rolling roller. The synchronizing gears are fixedly connected to one end of the synchronizing rods, and the two sets of synchronizing gears are meshed.

[0011] As a preferred technical solution of this application, the synchronizing element includes two sets of transmission rods and two sets of synchronizing pulleys. The two sets of transmission rods are respectively fixedly connected to one end of the second rolling roller and one end of the rotating rod. The synchronizing pulleys are fixedly connected to the side wall of the transmission rods, and a synchronizing belt is provided between the two sets of synchronizing pulleys.

[0012] As a preferred technical solution of this application, the inner cavity of the conveying cylinder is rotatably connected to a spiral conveying rod, a discharge pipe is inserted into one bottom end of the conveying cylinder, and a second motor for driving the spiral conveying rod to rotate is fixedly connected to one side wall of the conveying cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the scheme of this application:

[0016] 1. The first crushing roller is driven to rotate by the first motor. The first crushing roller drives the second crushing roller to rotate through the transmission component. The first crushing roller and the second crushing roller work together to crush the covering agent. At this time, the second crushing roller drives the rotating rod to rotate through the synchronizing component. The rotating rod drives the actuating rod to rotate. The actuating rod stirs the covering agent in the feeding box to prevent the covering agent from accumulating and clumping, thus ensuring the transportation quality of the covering agent.

[0017] 2. By setting up a baffle, the covering agent is stored in the feeding box. By pulling the positioning block, the positioning block drives the limiting rod to move longitudinally and moves the limiting rod out of the limiting hole, so that the positioning plate loses its limit. The moving plate drives the baffle to move horizontally, so that the covering agent can enter the conveying cylinder through the through groove, which facilitates the opening and closing of the through groove and makes it convenient to use.
