Description

An automated synthesis device for resin sand and antistatic liquid Technical Field

[0001] This utility model relates to a synthesis device, and more particularly to an automated synthesis device for resin sand and antistatic liquid. Background Technology

[0002] When resin sand is sprayed onto the surface of an aircraft, static electricity is generated due to friction between the resin sand and the pipes. Therefore, antistatic treatment is necessary before sandblasting. The usual method for antistatic treatment of resin sand is to add an antistatic liquid and thoroughly mix the antistatic liquid with the resin sand. Although there are existing synthesis devices that can thoroughly mix two different substances, the resin sand is a heavy particle, and the antistatic liquid has a certain adhesive force, resulting in high synthesis resistance. A large stirring force is required to achieve rapid synthesis. Ordinary mixing devices are more suitable for mixing liquids with good flowability but are not suitable for resin sand and antistatic liquid, leading to low synthesis efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an automated synthesis device for resin sand and antistatic liquid that is reasonably designed, easy to use, and has high synthesis efficiency, in order to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automated synthesis device for resin sand and antistatic liquid is characterized in that the device includes a frame, an upper tank for diluting the antistatic liquid, and a lower tank for mixing the resin sand and the antistatic liquid. The upper tank is placed on top of the lower tank, and the axis of the upper tank is offset from the axis of the lower tank. An antistatic liquid inlet is installed on the top of the upper tank, and a first outlet communicating with the lower tank is provided at the bottom of the upper tank. A first control valve is installed at the first outlet. Rollers for easy movement are installed at the four corners of the frame, and a first stirring device is installed inside the upper tank.

[0006] A water storage tank is installed on the top of the lower tank. The bottom of the water storage tank is connected to the first inlet located on the upper part of the upper tank through a water supply pipe. A water pump is installed on the water supply pipe.

[0007] A silo for storing resin sand is provided at the top of the lower tank. The silo is connected to the lower tank. A third control valve is installed at the opening connecting the silo and the lower tank. A second stirring device is installed inside the lower tank. The second stirring device is staggered from the first stirring device. A second outlet is provided at the bottom of the lower tank. A second control valve is installed at the second outlet.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: a viscosity sensor is installed on the inner wall of the upper tank, the viscosity sensor is installed in the middle and lower part of the upper tank, and a controller for controlling the water pump and the first control valve is installed on the outside of the upper tank. The controller is connected to the viscosity sensor signal to realize the automatic operation of the entire device.

[0009] The technical problem to be solved by this utility model can also be achieved by the following technical solution: the first stirring device includes a first stirring shaft and a first stirring blade mounted on the first stirring shaft. The two ends of the first stirring shaft are respectively mounted on the top and bottom of the upper tank through bearings. A first drive motor connected to the first stirring shaft is installed on the upper tank.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the first stirring blade is a paddle-shaped blade, a spiral blade, or an anchor-shaped blade.

[0011] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the second stirring device includes a second stirring shaft and a second stirring blade mounted on the second stirring shaft. The two ends of the second stirring shaft are respectively mounted on the top and bottom of the lower tank through bearings. A rubber shovel plate that mates with the bottom surface of the lower tank is fixed on the bottom edge of the second stirring blade to facilitate shoveling up the resin sand deposited at the bottom of the lower tank and effectively avoid sedimentation. A second drive motor connected to the second stirring shaft is installed on the lower tank.

[0012] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the second stirring blade is a spiral blade or an anchor blade, which can easily stir up the resin sand at the bottom of the lower tank while ensuring a good stirring effect, and prevent the resin sand from settling to the bottom.

[0013] The technical problem to be solved by this utility model can also be achieved by the following technical solution: rollers that are easy to move are installed at the four corners of the frame, so as to facilitate the movement of the entire device.

[0014] Compared with the prior art, this utility model adds an upper tank to premix the antistatic liquid with water, thereby diluting the antistatic liquid and reducing its adhesion. This facilitates the thorough and rapid mixing of the antistatic liquid with the resin sand later. The axes of the upper tank and the lower tank are staggered, as are the first and second stirring devices, which facilitates the stacking and installation of components and saves space. The addition of a water pump and a first control valve allows for easy control of the amount of water and antistatic liquid used, and timely monitoring of the adhesion strength of the antistatic liquid. The inclusion of a silo, a water storage tank, and a container unit allows the antistatic liquid, water, and resin sand to be integrated into a single device, avoiding excessive space occupation.

[0022] The first stirring device 6 includes a first stirring shaft and a first stirring blade mounted on the first stirring shaft. The two ends of the first stirring shaft are respectively mounted on the top and bottom of the upper tank through bearings. The first stirring blade is a paddle-shaped blade, a spiral blade, or an anchor-shaped blade. A first drive motor connected to the first stirring shaft is installed on the upper tank.

[0023] The second stirring device 9 includes a second stirring shaft and a second stirring blade mounted on the second stirring shaft.
