Description

Technical Field

[0001] The present application relates to the field of glaze screening devices, and in particular, to a ceramic glaze screening device and a screening method thereof. Background Art

[0002] The glaze applied on ceramics is generally made of quartz, feldspar, and clay. After being ground and mixed with water, it is applied to the surface of the green body and melted after being fired at a certain temperature. When the temperature drops, a thin glass layer is formed on the surface of the ceramic.

[0003] A sieve is needed in the screening process of ceramic glaze. Therefore, when the mesh size of the sieve is large, the sieved glaze particles are relatively large. When the mesh size of the sieve is small, although powder or smaller glaze particles can be screened out, the rate of passing the powder or smaller glaze particles through the sieve is limited by the smaller mesh size. It is also not easy to ensure the uniformity of the size of the sieved glaze particles, which reduces the quality of the glaze powder and the screening efficiency. Summary of the invention

At this time, large particles of ceramic glaze will be screened out and will be guided to the upper part of the barrel again through one side of the shaking screen. Then, it can be crushed and ground again together with new ceramic glaze, and then transported to the shaking screen for screening again. Therefore, even after large particles of ceramic glaze are screened out, they can be guided to the inside of the barrel for crushing and grinding again, without the need to transfer them to the inside of the crushing device, saving time and improving screening efficiency.

[0024] A ceramic glaze screening method according to an embodiment of the second aspect of the present application includes a ceramic glaze screening device according to the embodiment of the first aspect of the present application, and the following steps: S1, placing the pre-crushed ceramic glaze on the upper part of the screening end of the shaking screen, and the shaking screen screens the ceramic glaze; S2, the shaking screen will screen the ceramic glaze powder and fine particles into the dust box, and the larger particles of the ceramic glaze will be screened and exported through the shaking screen; S3, ceramic glaze powder and fine particles enter the dust box, forming dust inside the dust box. Ceramic glaze dust falls slowly under the action of gravity, and fine particles fall faster than powder under the action of gravity. At this time, the air and powder dust inside the dust box are extracted by the dust extraction speed of the dust extraction fan and extracted into the cyclone separator for separation by the cyclone separator; S4. Ceramic glaze dust and fine particles will fall to the upper part of the elastic part. At this time, the pull-down end of the pull-down part pulls down the middle part of the elastic part. After pulling down, the pull-down part is released to pull down the middle part of the elastic part. The elastic force of the elastic part instantly throws the ceramic glaze powder and fine particles on the upper part of the elastic part upward, and the screened ceramic glaze dust is again raised into the dust box. At this time, the dust extraction fan is used again to extract the ceramic glaze powder in the dust box into the cyclone separator, and the screened ceramic glaze powder is exported.

[0025] According to a ceramic glaze screening device according to an embodiment of the present application, the beneficial effects are: 1. The crushed ceramic glaze is placed on the upper part of the shaking box for screening. The screened glaze will fall into the dust box. At this time, the glaze dust is inside the dust box. Then the glaze that falls on the upper part of the elastic part will be thrown into the dust box again, that is, the screened glaze is dusted into the dust box again. The glaze with fine particles or powder glaze falls slowly, and the glaze with relatively large particles will fall faster due to gravity. The extraction speed of the dust extraction fan, that is, the extraction wind force, is adjusted so that the dust extraction fan can extract the dust, and the glaze with relatively large particles will not be extracted into the cyclone separator, thereby ensuring the uniformity of the particle size of the ceramic glaze after screening, and at the same time not limited by the rate of passing the net, ensuring the efficiency of screening; 2. The two symmetrically arranged dust extraction fan input ends extract the air inside the dust box, and the bottom of the dust box is blocked by an elastic part. Therefore, the air extracted by the dust extraction fan will enter the dust box through the shaking screen, thus forming a negative pressure inside the dust box. When the shaking screen screens the glaze, the occurrence of dust is reduced, thereby improving the dust reduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

The dust exhaust fan 250 and the cyclone separator 260 are symmetrically arranged, and the dust exhaust fan 250 and the cyclone separator 260 are fixedly connected to the equipment frame 100. The input end of the dust exhaust fan 250 is connected to the dust box 210, and the output end of the dust exhaust fan 250 is connected to one side of the cyclone separator 260.
