Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refractory brick production, in particular to an automatic refractory brick distributing device. Background Art
[0002] Refractory bricks, also known as firebricks, are refractory materials made from refractory clay or other refractory raw materials. They are pale yellow or brown in color and are primarily used in smelting furnaces. They can withstand temperatures of 1,580°C to 1,770°C. Production involves four steps: raw material processing, batching, mixing, and forming. Currently, the most commonly used forming method in refractory brick production is machine pressing, which uses a brick press and steel molds to press the clay into a green body. Currently, loading the green body press primarily relies on manual weighing. This not only cannot accurately guarantee weight, potentially affecting the quality of the refractory bricks, but is also time-consuming and labor-intensive, involves a harsh working environment, and poses certain safety risks. Therefore, we propose an automatic refractory brick feeding device. Utility Model Content

[0012] Beneficial effects
[0013] The utility model provides an automatic refractory brick distributing device, which has the following beneficial effects:
[0014] (1) This is an automatic feeding device for refractory bricks. When the material is stored in the hopper and is working, the material falls onto the feeding belt under the action of gravity. When the conveying belt is started, the material is transported and falls into the lower hopper. The material passing through the screen plate falls onto the conveying belt under the action of the oscillation motor and is transported to the weighing hopper. The accumulation of the material in the lower hopper is monitored by the level meter. When it reaches a specified level, the feeding belt stops working. When the weighing hopper weighs a certain mass of material, the baffle mechanism starts, the large baffle plate falls, and the amount of material falling into the weighing hopper is controlled. After reaching the specified weight, the small baffle plate falls, the bottom hopper plate of the weighing hopper opens, and the material falls into the feeding mechanism, and the second cylinder controls the feeding mechanism to be sent to the feeding station and the hopper plate is opened to discharge the material. The whole process is automatically controlled by the PLC control system. After the program is adjusted, it can work automatically, which has the advantage of a high degree of automation. Since there are multiple mechanisms for controlling the amount of material, the effect of accurate feeding can be achieved.
[0015] (2) This is an automatic refractory brick feeding device, in which an upwardly inclined feeding belt is provided at the bottom of the silo, and the feeding belt is fixedly installed at the discharge port below the silo. The purpose is to use the feeding belt to transport the material in the silo to the lower hopper, and the transportation is only achieved under the condition of starting. In the stopped state, even if the discharge port of the silo is opened, it will not cause material leakage, so as to improve the transportation stability during operation and reduce material waste.
[0016] (3) This is an automatic feeding device for refractory bricks. The baffle mechanism is divided into a large baffle plate and a small baffle plate. When the large baffle plate falls and the small baffle plate has not fallen, the material can be fed into the weighing hopper from the opening of the large baffle plate. When the small baffle plate also falls, the material will be blocked on the conveyor belt, thereby achieving the effect of accurately controlling the quality of the material falling into the weighing hopper.
