Technical Field

[0001] The utility model relates to the technical field of refractory material production, in particular to a pouring material production feeding device. Background Art

[0002] Refractory materials are divided into shaped refractory materials and unshaped refractory materials. Unshaped refractory materials usually refer to castables, which are mixed powder particles mainly composed of cement, quartz sand, high-alumina cement, silicate rubber powder and other additives, and have strong fluidity and plasticity. When preparing castables, a feeding device is required to feed a variety of prepared raw materials into a batching device according to proportion, and the finished castable is obtained by stirring and mixing. The conveyor belt surface of the currently commonly used castable feeding device is easily attached to the castable to form a thin layer of material, which is difficult to remove.

[0003] The Chinese utility model patent with the authorization announcement number CN217330605U discloses a feeding device for casting material production, which scrapes the casting material attached to the first conveyor belt twice by means of a guide plate and a scraper to keep the surface of the first conveyor belt clean. However, the defect is that the casting material is easy to spill from the edge of the conveyor belt, and the feeding device needs to be cleaned regularly or an additional conveying device needs to be set up to send out the spilled casting material, which is inconvenient to use. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a casting material production feeding device, including a shell and a conveyor belt. The shell is inclined and has a feed port and a discharge port. The conveyor belt is arranged in the shell and extends to the discharge port. The opposite inner walls of the shell are rotatably installed with paddles. Multiple paddles are arranged along the direction of the conveyor belt. A torsion spring is installed between the paddle plate and the shell, and the end of the paddle plate contacts the surface of the conveyor belt.

[0006] The casting material production feeding device provided by the utility model also has the following technical features:

[0007] The opposite inner walls of the shell are both provided with mounting grooves, and a shifting plate is rotatably mounted in the mounting groove.

[0008] A support shaft is fixed in the mounting groove, the support shaft is rotatably connected with the shift plate, a torsion spring is sleeved outside the support shaft, one end of the torsion spring is fixed to the housing, and the other end is fixed to the shift plate.

[0009] A baffle is fixed in the shell, the baffle is arranged below the feed port and perpendicular to the conveyor belt, and the baffle is in contact with the surface of the conveyor belt.

[0010] A scraper is fixed at the discharge port of the shell, and the end of the scraper is in contact with the surface of the conveyor belt.

[0011] A drying component is fixed in the shell and is arranged below the conveyor belt.

[0012] A feed hopper is fixed on the shell body, and the feed hopper is communicated with the feed port.

[0013] The conveyor belt is sleeved outside two conveyor rollers, the conveyor rollers are rotatably connected to a shell, a motor is fixed outside the shell, and an output shaft of the motor is fixed to one of the conveyor rollers.

[0014] The utility model has the following beneficial effects: material is fed into the shell through the feed port, the castable material falls on the surface of the conveyor belt, and a castable paddle distributed on the edge of the conveyor belt rotates. Under the action of the torsion spring, the paddle pushes the castable material from the edge of the conveyor belt in the opposite direction to a position close to the center, thereby preventing the castable material on the edge of the conveyor belt from spilling into the shell, and there is no need to clean or set up an additional conveying device, so it is easy to use.
