Description

A device for spraying release agent

technical field

The utility model belongs to the field of vertical formwork light wallboard production, in particular to a device for spraying a release agent.

Background technique

In the actual production process of the grouped molded lightweight wallboards currently on the market, a certain amount of soapy water and engine oil (32# engine oil ) for blending, and then apply the blended release agent to the surface of the mold partition. However, in the actual production process, after the soapy water and engine oil are blended, the water and the oil cannot be fused into a state of oil-water separation, which cannot meet the production requirements; after the blending of the two is completed, use a mop to apply the blended release agent To the surface of the mold partition, the release agent adheres unevenly to the surface of the mold partition, resulting in an uneven surface of the wallboard after demoulding, with a high rate of uneven defective products, and the surface of the mold partition also needs to be cleaned manually.

Utility model content

In order to solve the above technical problems, the utility model provides a device for spraying release agent, which can fully mix soapy water and engine oil, and can evenly apply it to the surface of the mold partition to improve the rate of qualified products.

In order to achieve the above object, the utility model is achieved through the following technical solutions.

A device for spraying a release agent, comprising a release agent container, a mixing device, a conveying device, and a spray gun, the mixing device is installed on the upper part of the release agent container, and the release agent container is connected to the spray gun through the conveying device. The release agent is mixed with a certain amount of soapy water and engine oil. After the soapy water and engine oil are blended, the two cannot be completely integrated, and the oil and water are separated. Use a mixing device to mix the engine oil and soapy water evenly, and spray evenly through the delivery device and spray gun to the mold spacer surface.

The mixing device includes a motor, a rotating shaft, and a blade. The rotating shaft extends vertically into the release agent container. One end of the rotating shaft is a fixed end and the other is a free end. The fixed end of the rotating shaft is connected to the output end of the motor, and the blade is installed on the rotating shaft. superior. Turn on the stirring motor, and the stirring blades rotate to make the oil and soapy water roll up and down in the barrel to achieve uniformity.

There are 3 to 4 groups of blades, and the size of the blades closer to the free end of the rotating shaft is smaller. There is an included angle of 30-90° between any group of blades and the projection in the vertical direction of an adjacent group of blades. There are at least 2 blades in each group, and the blades form an angle of 15-30° with the horizontal plane. Since water and oil cannot be mixed, the degree of stirring must be increased to make the oil form tiny droplets and mix with water to fully emulsify, so as to meet the production requirements. Simply increasing the speed and number of blades will not only increase the power consumption significantly, but also the mixed liquid will always rotate synchronously in the release agent container and will not be fully emulsified, which will not meet the production requirements. Therefore, after the blade is made to form an angle of 15-30° with the horizontal plane, the rotating blade can not only make the liquid rotate horizontally in the container but also make the liquid close to the center of the rotating shaft flow downward, and then flow upward along the inner wall of the container after reaching the bottom of the container. It increases the degree of chaos of the liquid in the container and emulsifies the liquid. In order to further increase the emulsification effect, blades can be added to 3-4 groups on the rotating shaft, and the angle between any group of blades and the vertical projection of the adjacent group of blades is 30-90°. In order to make the liquid flow down smoothly, the closer to the bottom, the smaller the vane size.

The delivery device includes a pipeline, a booster pump, and a valve. The valve is installed at the bottom outlet of the release agent container. The inlet of the booster pump is connected to the valve through a pipeline, and the outlet of the booster pump is connected to the spray gun through a pipeline. The pipeline is a pressure-resistant hose. The pipeline booster pump has simple and compact structure, small size, light weight, few parts, convenient manufacture, low cost, and small footprint, so its equipment and repair costs are relatively cheap. The pressure-resistant hose 34 is a hose with chemical corrosion resistance, light weight, high wear resistance, anti-staining, anti-flatulence and other properties.

2-4 spoilers are installed on the inner wall of the release agent container. Installing a spoiler can disturb the liquid rotating horizontally along the inner wall of the container and add it to the liquid flowing up and down to further increase the degree of emulsification.

Beneficial effect: compared with the prior art, the utility model has the advantages of:

1) Fully mix soapy water and engine oil to meet production requirements;

2) It can reduce the labor intensity of the employees. The employees only need to hold the spray gun and walk over the parts to be sprayed, and can evenly apply the release agent to the surface of the mold partition to increase the rate of qualified products;

3) Shorten working time and improve production efficiency.

4) The utility model has low input cost, low post-maintenance cost, and great benefits. The utility model input cost is 3,500 yuan, and the unit price of production cost can be reduced by 60%.
