Casting flow coating device with warning function

Abstract

The invention relates to a casting flow coating device with a warning function. The casting flow coating device comprises a spraying workbench, a filter device, a charging tank, a water pump and a spray gun, wherein a funnel-shaped paint recycling device is arranged in the spraying workbench; the upper end surface of the paint recycling device is parallel to the upper end surface of the spraying workbench; the lower end of the paint recycling device is communicated with the charging tank through a first pipeline; the filter device is arranged at a communicated part of the paint recycling device and the first pipeline; a charging hole is formed in the upper end of the charging tank; the water pump is arranged at one side, far from the first pipeline, of the charging tank; a feeding hole of the water pump is communicated with the charging tank; a discharging hole of the water pump is communicated with the spray gun through a second pipeline; the spray gun is arranged above the spraying workbench; a formaldehyde detector, a master control system and an alarm are arranged on the side wall of the spraying workbench; and the formaldehyde detector, the master control system and the alarm are sequentially connected through a circuit. Compared with the prior art, the casting flow coating device can warn the formaldehyde concentration, can improve the spraying efficiency and can improve the spraying quality.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a casting flow coating device with warning function. Background technique [0002] Coating is an important auxiliary material in the casting production process and plays an important role in the production of casting molds. Cooperating with furan resin sand can obtain good casting surface quality and prevent molten iron from penetrating into sand molds. The gas forms a barrier interface to prevent casting defects such as sticky sand and pores; [0003] Coatings are generally applied by manual brushing. The manual brushing method has high flexibility, low production efficiency and high labor intensity, but requires skilled workers and no brush marks, which have a certain impact on the appearance quality of castings. Especially in grooves and thin-walled parts, manual brushing is easy to accumulate paint, resulting in lack of meat in the casting; moreover, the spraying device in t...

[0003] The paint is generally applied by manual brushing. The manual brushing method has high flexibility, low production efficiency and high labor intensity, but requires skilled workers and no brush marks, which have a certain impact on the appearance quality of castings.

Especially in grooves and thin-walled parts, manual brushing is easy to accumulate paint, resulting in lack of meat in the casting; moreover, the spraying device in the prior art does not have a warning function
