Description

Technical Field

[0001] This utility model relates to the field of refractory castable technology, and in particular to a raw material feeding device for refractory castable. Background Technology

[0002] Refractory castables consist of three parts: binder, aggregate, and admixtures, sometimes with the addition of accelerators. Refractory aggregates form the main body of refractory concrete; various refractory materials, after calcination, or various waste bricks crushed to a certain extent can be used as refractory aggregates. The binder acts as a binder and hardener, giving the product a certain strength. Admixtures are added to improve the performance of refractory concrete, such as increasing strength during heating and reducing volume shrinkage; typically, 10% to 25% of these admixtures are added.

[0003] In the current refractory castable, the feeding process often relies on a feeding belt, which generates a lot of dust and pollutes the workshop. Furthermore, the material cannot be directly fed into the mixing tank, resulting in a slow feeding speed. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please refer to Figures 1-2A raw material feeding device for refractory castable includes a feeding transfer tank 1, a feeding motor 2 is fixed vertically downward at the top of the feeding transfer tank 1, and a feeding pipe 3 is provided at the bottom of the tank.

[0025] A feeding rod 4 is fixed on the rotor of the feeding motor 2. The feeding rod 4 extends into the interior of the feeding pipe 3. A spiral discharge fan blade 5 is provided at the bottom of the feeding rod 4. The spiral discharge fan blade 5 extends into the interior of the feeding pipe 3. An electric valve 6 is provided at the outlet of the feeding pipe 3.

[0026] A vacuum feeding pump 7 is provided on the left side of the feeding transfer tank 1. The vacuum feeding pump 7 is connected to the feeding transfer tank 1 through a vacuum adsorption pipe 8. A filter screen 9 is provided inside the feeding transfer tank 1.

[0027] The loading transfer tank 1 is connected to the storage silo 11 via a conveying pipe 10.

[0028] In this embodiment, the device can directly transfer the material in the storage bin 11 to the external mixing tank, thereby improving the feeding rate; the feeding process of this device adopts sealed feeding, which can effectively prevent dust from escaping into the workshop and polluting the workshop environment.

[0029] A cleaning rod 12 is fixed on the feeding rod 4, and the cleaning rod 12 is located below the filter screen plate 9. Several cleaning bristles 13 are provided above the cleaning rod 12, and the cleaning bristles 13 are attached to the bottom of the filter screen plate 9. In this embodiment, after the vacuum feeding pump 7 stops operating, that is, after a certain amount of material is stored in the feeding transfer tank 1, when the feeding motor 2 drives the spiral discharge fan blade 5 to perform the material discharge operation, the cleaning rod 12 rotates with the feeding rod 4, which can clean the impurities adsorbed on the filter screen plate 9.

[0030] In this embodiment, the bottom of the storage bin 11 is funnel-shaped, which allows the raw materials to flow to the conveying pipe 10, thereby facilitating adsorption and feeding and improving the feeding rate.

[0031] Several feeding devices are distributed on the outer wall of the storage silo 11. Each feeding device includes a feeding motor 14, which is inclinedly mounted on the outer wall of the storage silo 11. A feeding rod 15 is fixed on the rotor of the feeding motor 14 and extends inclinedly towards the bottom of the storage silo 11. A spiral feeding fan blade 16 is provided on the feeding rod 15. In this embodiment, the feeding motor 14 drives the spiral feeding fan blade 16 to rotate, which can guide the raw material in the storage silo 11 to the inlet of the conveying pipe 10, thereby facilitating adsorption and feeding and improving the feeding rate.

[0032] A screw conveyor 17 is connected to the bottom of the feeding pipe 3. The output end of the screw conveyor 17 is provided with a discharge pipe 18, which is located on the top of the external mixing tank. In this embodiment, the screw conveyor 17 can directly transfer the material stored in the feeding transfer tank 1 to the mixing tank.

[0033] Working principle: Start the vacuum feeding pump 7. Under the action of the vacuum feeding pump 7, the raw materials in the storage bin 11 are transported to the feeding transfer tank 1 through the conveying pipe 10 under the action of vacuum adsorption force. During the conveying process, the feeding motor 14 drives the spiral feeding fan blade 16 to rotate, and guides the raw materials in the storage bin 11 to the feed port of the conveying tank in real time.

[0034] After the feeding transfer tank 1 stores a certain amount of raw materials, the vacuum feeding pump 7 is turned off, the electric valve 6 is opened, and the feeding motor 2 is started to drive the spiral discharge fan blade 5 to rotate. The spiral discharge fan blade 5 transports the raw materials into the feeding pipe 3. At the same time, the spiral conveyor 17 is started. Under the action of the spiral conveyor 17, the raw materials are guided to the external mixing tank for mixing.
