Self-cleaning method and device for ceramic slurry spray-drying spraying gun

Abstract

The invention relates to a self-cleaning method and device for a ceramic slurry spray-drying spraying gun. According to the method, a vibrator or a beating mechanism is arranged at the gun base position of the bottom of the spray-drying tower spraying gun, vibrating or beating force is transmitted to a spraying gun head through the body of the spraying gun, and then caked powder bonded to a nozzle of the spraying gun can fall off from the nozzle under the external vibrating or beating force. The method is used for cleaning the nozzle of the spraying gun without manual beating and has obvious effects in stabilizing the quality of powder and reducing the labor intensity of operators. The device comprises a vibrator installation base, the vibrator or beating mechanism and a vibration controller, wherein the vibration frequency, vibration time and time interval of the vibrator or beating mechanism are controlled through a time relay.

Description

technical field [0001] The invention relates to the preparation of pressed powder used for dry pressing of ceramic tiles, the field of spray drying tower technology and equipment used, and further relates to a self-cleaning method and device for a spray gun of a spray tower. Background technique [0002] The spray drying tower is the necessary equipment for powder preparation in the production process of ceramic tiles. The mud is sprayed out through the spray gun and dehydrated and dried into powder with certain moisture and particle size under the action of hot air. In the process of spray drying and powder making, the clogging of the spray gun has always been the technical key to the powder production and quality. During the process of spraying and drying the mud into powder, there will inevitably be mud or powder accumulation, which will accumulate on the nozzle of the spray gun and cause the nozzle to be blocked. , affecting the quality of the spray-dried powder, and the...

Problems solved by technology

In the process of spray drying and powder making, the clogging of the spray gun has always been the technical key to the powder production and quality. During the process of spraying and drying the mud into powder, there will inevitably be mud or powder accumulation, which will accumulate on the nozzle of the spray gun and cause the nozzle to be blocked. , affect the quality of the spray-dried powder, and the cleaning process needs to interrupt the normal production, resulting in a decline in production efficiency

[0003] Application No. 200510031987.4 "Metallurgical blast furnace pulverized coal spray gun clogging automatic monitoring system" uses a purge pressure detection device to detect the clogging situation; Application No. 201310405231.6 "A device and method for preventing blast furnace spray gun coke oven gas tank from clogging" uses ultrasonic probe insertion The way in the gas tank, the problem of reducing the deposition of organic substances on the pipe wall by generating ultrasonic waves through the ultrasonic generator; the application number 201110352548.9 "Spray gun cleaning device and cleaning method" and other industries' cleaning methods for spray drying spray gun nozzles cannot solve the problem of the ceramic industry. The accumulation of mud / dry powder caused by mud spray drying and pulverization leads to the problem of clogging of the nozzle of the spray gun
