The first slide rail limits a certain range for the forward and backward movement of the moisture-proof assembly. After the moisture-proof component moves out of the feed port, the first electric slider drives the components on its upper surface to move within the range limited by the first slide rail, so that the moisture-proof component leaves the feed port, providing space for the raw materials to enter the feed port position. A combination of a second slide rail and a second electric slider is adopted, and the second slide rail is used to provide a certain range for the up and down movement of the second electric slider, and the second electric slider can drive the components on its lower surface to move up and down within the range limited by the second slide rail, so that the components at the lower end of the second electric slider can be lifted and leave the interior of the feed port.

A proper amount of powder, such as alumina powder, silicon powder, etc., is added to fill the gaps between the aggregates, improve the density and integrity of the castable, and enhance its erosion resistance. Binders such as calcium aluminate cement, silica sol, phosphoric acid and phosphates are added. The function of the binder is to bond the aggregate and powder together, giving the castable good construction performance and normal temperature and high temperature strength. Finally, some additives are added as needed, such as water reducers, accelerators, expansion agents, etc. The water reducer can reduce the water consumption of the castable, improve its fluidity and strength, and ensure that the aggregate, powder, binder and The dosage of additives is accurate to ensure the stable performance of the castable. The weighed aggregate, powder and additives are first dry-mixed in a mixer. An appropriate amount of water and binder are added to the dry-mixed materials for wet mixing. The stirred castable is poured into the mold and vibrated by a vibrating table, an inserted vibrator or manual tamping to make the castable densely fill the mold and expel the air therein to ensure the density and dimensional accuracy of the product. The molded castable is cured at room temperature for 24-48 hours to allow the castable to initially condense and harden under the action of the binder to obtain a certain strength. The cured castable product needs to be baked before use to remove free water and crystallization water and improve its high-temperature performance. According to the above steps, the process flow of low thermal conductivity, corrosion-resistant and lightweight refractory castable is completed.

8. The low thermal conductivity, corrosion resistant and lightweight refractory castable according to claim 1, characterized in that: The chassis assembly (4) comprises a chassis body (41) inside, and a plurality of power supply compartments (42) are hingedly mounted on the outer surface of the chassis body (41).

9. The low thermal conductivity, corrosion resistant and lightweight refractory castable according to claim 8, characterized in that: A plurality of tires (43) are fixedly mounted on the lower surface of the chassis body (41), and a plurality of legs (44) are fixedly mounted on the left and right outer surfaces of the chassis body (41); The inner surface of the storage box (12) comprises a refractory castable material (5).

10. The method for preparing a low thermal conductivity, corrosion resistant and lightweight refractory castable according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: The sealing cover (26) inside the feed port (21) is driven by the second electric slider (25) to move upward within the range defined by the second slide rail (24), so that the sealing cover (26) drives the hanging basket (27), the baffle (28) and the desiccant (29) to leave the inside of the feed port (21), thereby vacating the space occupied by the feed port (21). Then, the first electric slider (23) drives the second slide rail (24) on its upper surface to move within the range defined by the first slide rail (22), thereby removing the moisture-proof assembly (2) from the upper surface of the feed port (21), so that the refractory castable material (5) can smoothly enter the inside of the storage assembly (1). The desiccant (29) is used to preferentially absorb moisture inside the storage assembly (1) to achieve deep drying. Step 2: The interior of the storage assembly (1) is used to store the refractory castable material (5); the sealing ring (13) is used to increase the sealing performance between the cover plate (11) and the storage box (12), further improving the ability of the storage assembly (1) to resist an external humid environment; and the buckle (15) can prevent the cover plate (11) from sliding off the upper surface of the storage box (12); Step 3, the electric valve (39) controls the flow rate of the refractory castable material (5) entering the conveying assembly (3), and the (36) inside the conveying assembly (3) is driven by the threaded rod (32) to rotate, and the refractory castable material (5) is conveyed from the electric valve (39) to the outlet of the discharge port (33) to complete the conveying of the refractory castable material (5); Step 4: The chassis body (41) serves as the installation base of the entire device and as the main component of the chassis assembly (4), it can provide a foundation for the installation and fixation of other components. The chassis body (41) and the tires (43) enable the device to be moved between different work sites. After reaching the working position, the legs (44) can support the device by extending the hydraulic cylinder contained in the legs (44) downward so that the fixing block contained in the lower piston rod of the hydraulic cylinder contacts the ground.
