Their main function is to withstand thermal stress and chemical erosion in high-temperature environments. Refractory furnace materials are widely used in industries such as iron and steel smelting, bauxite smelting, glass manufacturing, and cement production. With the continuous development of these industries, the demand for refractory furnace materials is also increasing. Among them, during the production process of refractory furnace materials, filling equipment is required.

One side of the machine body is fixedly connected with a feeding funnel, and a movable shaft is installed on the right side of the feeding funnel. The top of the movable shaft is movably connected with a dust-proof cover, and a partition plate is installed below the dust-proof cover. A vibration pump is connected between the partition plate and the outer wall of the feeding funnel. In the utility model, under the action of the lifting mechanism, the electric telescopic rod can lift the loading bucket on its placement plate, so that the feeding pipeline is wrapped inside the loading bucket, and thus the powder can be discharged into the loading bucket through the material limiting mechanism. When the loading is completed, the placement plate is lowered by the electric telescopic rod and reaches the electronic scale. The electronic scale has been tared, so the weight of the powder in the loading bucket can be accurately measured. Through this lifting mechanism, the powder loading work can be facilitated, and the powder in the loading bucket can be accurately weighed.

A flow regulating component 4 is fixedly connected to the middle of the powder filling head 1. Brackets 8 are welded on both the left and right sides of the flow regulating component 4. A cylinder 9 is fixedly installed on the end face of the bracket 8, and a rubber sealing block 10 is fixedly connected to the piston rod of the cylinder 9 through the flow regulating component 4. The flow regulating component 4 is communicated with the powder filling head 1, and the rubber sealing block 10 is in contact with the inner wall of the flow regulating component 4. A blanking cloth tube 3 is sleeved and installed at the bottom of the powder filling head 1, and an annular clamp 13 is fixed to the connection between the blanking cloth tube 3 and the powder filling head 1 through flat head screws.

By starting the cylinders 9 installed on the two brackets 8 to extend by a fixed length respectively, the rubber sealing blocks 10 arranged at the opposite ends of the two cylinders 9 are urged to move towards each other. As the two rubber sealing blocks 10 approach each other, the blanking diameter inside the powder filling head 1 gradually decreases, regulating the filling flow rate of the refractory furnace charge and avoiding the weighing weight error caused by the too large filling flow rate of the refractory furnace charge. By connecting the blanking cloth tube 3 to the bottom of the powder filling head 1 with an annular clamp 13, and a counterweight ring 14 is sleeved at the bottom of the blanking cloth tube 3. When the refractory furnace charge is led out from the powder filling head 1, the blanking cloth tube 3 blocks the dust overflowing during the falling stage of the refractory furnace charge, and the turbulent air passes through the blanking cloth tube 3, achieving the purpose of dust prevention during the bagging stage. The stroke of the cylinder 9 can be adjusted by manually rotating the adjustable screw on the cylinder 9 to adjust the telescopic length of the cylinder 9. The cylinder 9 is also equipped with a gas source for the telescopic movement of the cylinder 9. Specifically, it is the prior art known to the public and will not be elaborated too much.

[0024] In one embodiment, the material of the unloading cloth tube 3 is a woven fabric of polyester or acrylic, and the annular clamp 13 and the counterweight ring 14 of the unloading cloth tube 3 are the same size. Due to the hollow structure on the surface of the woven fabric, a dust filtering structure can be formed. The setting of the counterweight ring 14 can prevent the unloading cloth tube 3 from being offset due to the wind direction during the bagging stage.

[0025] In one embodiment, the flow regulating component 4 is an oblong shell as a whole, and clearance holes are provided at both ends of the flow regulating component 4 corresponding to the piston of the cylinder 9, wherein the internal space of the oblong shell is adapted to the size of the rubber sealing block to prevent the refractory charge from being discharged downward through the gap between the oblong shell and the rubber sealing block.

[0026] In one embodiment, a screw hole is provided on the upper surface of the reinforcement strip 5, and the position of the screw hole corresponds to the position of the thread groove on the surface of the mounting block 7.

The support ring 12 is provided to maintain the reliability of the connection with the threaded nozzle at the bottom of the silo 2 .

[0028] Working principle:

[0029] When in use, firstly, the threaded end 11 at the top of the powder filling head 1 is threadedly connected with the threaded nozzle at the bottom of the silo 2. When the reinforcement strip 5 welded obliquely on the outer wall of the threaded end 11 corresponds to the mounting block 7 provided on the lower surface of the silo 2, the bolt 6 is used to penetrate the threaded groove on the surface of the reinforcement strip 5 and the mounting block 7 to thread the powder filling head 1. When the refractory furnace charge is filled and bagged, the cylinders 9 installed on the two brackets 8 are started to extend at a fixed length respectively, so that the rubber sealing blocks 10 provided at the opposite ends of the two cylinders 9 move toward each other. As the two rubber sealing blocks 10 The two ends of the powder filling head 1 are close to each other, so that the discharge diameter inside the powder filling head 1 is gradually reduced, and the filling flow rate of the refractory charge is adjusted to avoid the weighing weight error caused by the excessive filling flow rate of the refractory charge. At the same time, the discharge cloth tube 3 is connected with the annular clamp 13 at the bottom of the powder filling head 1, and a counterweight ring 14 is sleeved on the bottom of the discharge cloth tube 3.
