Automatic slurry spreading device and method for bottoms of ceramic unburied bricks

Abstract

The invention relates to an automatic slurry spreading device and method for the bottoms of ceramic unburied bricks. The device comprises an unburned brick conveying mechanism for slurry spreading with a rubber roll embossing machine, and a bottom slurry cylinder and a bottom slurry transfer cylinder are sequentially arranged beside the rubber roll embossing machine. A second bottom slurry pump arranged in the bottom slurry cylinder communicates with the rubber roll embossing machine through a slurry feeding hose. A first bottom slurry pump is arranged in the bottom slurry transfer cylinder, aglaze discharging pipe communicating with the first bottom slurry pump stretches into the bottom slurry cylinder, and the bottom slurry cylinder and the bottom slurry transfer cylinder are provided with a cooling circulation system. The rubber roll embossing machine communicates with the bottom slurry transfer cylinder through a slurry returning pipe, and residual bottom slurry is recovered intothe bottom slurry transfer cylinder. The first bottom slurry pump and the second bottom slurry pump are each provided with a slurry feeding pipe and a stirring mechanism located at the end of the corresponding slurry feeding pipe. The bottom slurry is evenly spread on the bottoms of the unburned bricks through a rubber roll, uniformity of the slurry spreading thickness is achieved through adjusting equipment, the situation that the bottom slurry is prone to sediment, caking and concentration instability because the temperature of the glaze slurry is increased in the long-time circulation process is effectively prevented, and the situation that the slurry spreading uniformity is influenced by non-uniform mixing concentration of original bottom slurry glaze and the recovered glaze slurry isprevented.

Description

technical field [0001] The invention relates to the field of ceramic tile production, in particular to an automatic slurry distributing device at the bottom of ceramic tile adobes and a slurry distributing method thereof. Background technique [0002] CN201620417238.9 discloses an automatic bottom pulping machine, including a slurry tank, a stirring shaft and a roller shaft are arranged in the slurry tank, and the stirring shaft and the roller shaft are respectively connected with a drive motor arranged outside the slurry tank, The roller shaft is set above the stirring shaft, the upper surface of the roller shaft is flush with the upper end of the slurry tank, the slurry tank is filled with slurry, and the slurry level of the slurry is higher than the lower surface of the roller shaft, and the stirring shaft is submerged In the slurry, the adobe passes through the roller, and the adobe dips the slurry on the surface of the roller to complete the step of applying the primer....

AI Technical Summary

Problems solved by technology

[0009] ⑴Because the hollow soft rubber tube is not fixed, it is easy to deviate, resulting in uneven bottom of the adobe during the grouting process;

[0010] (2) Due to the use of a single slurry tank for the bottom slurry, when adding the brick bottom slurry, it is easy to add the thick slurry first and then add tap water, resulting in the undesirable phenomenon of uneven thickness of the brick bottom slurry;

[0011] ⑶The control of the thickness of the base slurry is restricted by the adsorption capacity of the hollow soft rubber tube, and can only be adjusted through the concentration of the base slurry, which is a single method;

[0012] ⑷Because the temperature of the adobe is higher than the temperature of the bottom slurry, the temperature of the bottom slurry will increase during the long-term recycling process, thereby destroying the performance and concentration of the bottom slurry
