Description

Technical Field

[0001] The invention relates to the technical field of glass raw material processing, in particular to a device and method for fine processing of ultra-white glass raw material feeding. Background Art

[0002] Ultra-clear glass is an ultra-transparent low-iron glass, also known as low-iron glass and high-transparency glass, with a light transmittance of more than 91.5%. Ultra-clear glass also has all the processability of high-quality float glass, with excellent physical, mechanical and optical properties, and can be processed in various ways like other high-quality float glass. The unparalleled superior quality and product performance give ultra-clear glass a broad application space and a bright market prospect.

[0003] In the production process of ultra-white glass, it is required that iron equipment is used as little as possible in the raw material feeding system to ensure that the iron content in the ultra-white component is below 0.0125ppm. Silica sand, soda ash, limestone, feldspar, broken glass and other raw materials for glass production are inevitably in contact with iron equipment in the pre-treatment process, such as crushing, screening, drying and other processes. In particular, the crushing process generally uses a pair of rollers, so further iron removal is required before the raw materials are put into the furnace. Generally, iron removal equipment such as magnetic drum belts are used. This type of equipment cannot effectively change the state of the material layer when removing iron, that is, the upper and lower layers and the state before and after the material layer of a certain thickness remain unchanged before and after iron removal, and the material will not be broken up for fine iron removal. The iron impurities in the inner layer of the material or tightly combined with the material cannot be effectively removed, and the iron content of ultra-white glass cannot be reduced to the limit. Summary of the invention

[0004] The purpose of the present invention is to provide a fine processing device and method for ultra-white glass raw material feeding, so as to solve the problem that traditional equipment cannot effectively change the state of the material layer when removing iron, the iron impurities in the inner layer of the material or tightly combined with the material cannot be effectively removed, and the iron content of the ultra-white glass cannot be reduced to the limit.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An ultra-white glass raw material feeding fine processing equipment, comprising:

[0007] An outer cylinder body, wherein the outer cylinder body is provided with a lower sand opening, a sand outlet and an iron outlet;

[0008] A material displacing cylinder, which is rotatably mounted in the outer cylinder, and a plurality of independent and sealed sand storage chambers are formed between the outer periphery of the material displacing cylinder and the inner periphery of the outer cylinder;

[0011] One end of the material displacing cylinder extending out of the outer cylinder is connected to the power output end of the motor through a transmission structure.

[0012] A further technical solution is: a vibration component is arranged inside the magnetic cylinder and passes through the magnetic cylinder and is connected to the inner cylinder.

[0013] A further technical solution is: the vibration assembly includes a support rod, a shell and a vibrator, one end of at least one of the support rods passes through the magnetic cylinder and is connected to the inner cylinder, the shell is installed on the other end of the support rod, and the vibrator is installed in the shell.

[0014] A further technical solution is that sound insulation boards are provided at both ends of the inner cylinder.

[0015] A further technical solution is: a heating element is arranged in the inner cylinder, and the heating element is an electric heating wire or a heat conducting pipe.

[0016] A further technical solution is: an iron removal assembly is provided on the iron outlet, and the iron removal assembly includes a cover body, a scraper and a tension spring.

The tension spring tightens the cover body and the scraper respectively, and the inner end of the scraper is pressed against the outer peripheral surface of the material discharging barrel.

[0017] A method for finely processing ultra-white glass raw material feeding, using ultra-white glass raw material feeding fine processing equipment, the processing method is as follows:

[0018] S1. Raw materials such as silica sand, soda ash, limestone, feldspar, and broken glass are crushed by a crusher, and the single material or mixed material is sent to the sand discharge port through a conveying device, which can be a screw conveyor or a belt conveyor;

[0019] S2. A material sensor can be set at the sand discharge port to automatically start the motor, or the motor can be started manually. The material barrel rotates along the circumference with the material in the sand storage chamber. The position of the material keeps changing to achieve the effect of turning the material. The iron impurities in the material are effectively adsorbed on the inner wall of the material barrel.

[0020] When the material turning effect is not good, the vibrator can be started, and the vibration component can be used to produce a vibration effect on the material to promote the separation of iron impurities;

[0021] When the material turning effect is not good, the heating element can be started to dry the material, and the water vapor is discharged through the exhaust port on the side of the outer cylinder to promote the separation effect of iron impurities, while ensuring the sealing effect of the material;

[0022] The heating element and the vibration component can be used alone or simultaneously.

[0023] S3, the material rotates to the sand outlet and is discharged, leaving iron impurities on the material dispensing barrel and continuing to rotate, and the iron impurities rotate to the iron outlet and lose magnetic force and are discharged;

When the material turning effect is not good, the vibrator can be started, and the vibration component intervenes to produce a vibration effect on the material to promote the separation effect of iron impurities. The heating element can also be started to dry the material, and the water vapor is discharged through the exhaust port on the side of the outer cylinder to promote the separation effect of iron impurities. The sealing effect of the material is ensured while exhausting. It not only ensures continuous material processing, but also can finely discharge iron impurities in the material to ensure the production quality of ultra-white glass.
