Anti-corrosion layer coating device for inner wall of cast iron pipe

Abstract

The invention discloses an anti-corrosion layer coating device for the inner wall of cast iron pipes. The anti-corrosion layer coating device comprises a base and is characterized in that a left roller seat and a right roller seat are fixedly arranged on the base, cast iron pipes are rotatably arranged on the left roller seat and the right roller seat, and a galling machine base is arranged at one end of the cast iron pipes, a galling head is connected to the galling machine base in a transmission mode through a motor, the left roller seat and the right roller seat are provided with a left support column and a right support column, the left support column is provided with a crossbeam plate. According to the anti-corrosion layer coating device, cement spraying pipes are fixed in the cast iron pipes, and the inner walls of the inner pipes are sprayed cement layers through cement mixing tanks, and the uniformly spraying of the cement on the inner walls of the cement pipes is achieved under the high-speed rotation of the cast iron pipes. After drying of the cement layers, an ultrasonic probe is used to detect the degree of uniformity of the spraying.

Description

technical field [0001] The invention relates to cast iron production equipment, in particular to a device for applying an anti-corrosion layer on the inner wall of a cast iron pipe. Background technique [0002] In the daily cast iron pipe production process, the internal spraying of cast iron pipes requires an internal spraying machine and a trolley for internal spraying treatment. When the internal spraying machine sprays the lining of a cast pipe, wait for it to cool to solidify before proceeding to the next step. The internal spraying treatment of a cast pipe makes the production time unable to be fully utilized, which virtually leads to low production efficiency. In the field of centrifugal casting, some ductile iron pipes will be locally deformed after centrifugal drawing and high temperature annealing. These damaged and bent ductile iron pipes need to be straightened before they can be put into service. At present, manual beating is often used for straightening, whic...

[0002] In the daily cast iron pipe production process, the internal spraying of cast iron pipes requires an internal spraying machine and a trolley for internal spraying treatment. When the internal spraying machine sprays the lining of a cast pipe, wait for it to cool to solidify before proceeding to the next step. The internal spraying treatment of a cast pipe makes the production time unable to be fully utilized, which virtually leads to low production efficiency. In the field of centrifugal casting, some ductile iron pipes will be locally deformed after centrifugal drawing and high temperature annealing. These damaged and bent ductile iron pipes need to be straightened before they can be put into service

At present, manual beating is often used for straightening, which has poor straightening effect and wastes manpower
