Problems solved by technology
[0003] The existing foundry sand needs to go through a series of treatments before it can be used in the foundry process. Now the transportation method of foundry sand is belt transportation. The disadvantage of this transportation method is that the belt uses the distance between it and the casting sand pile The friction generated between them drives the casting sand to move, and the transport speed of the belt is determined by the rotation of the motor. To increase the transport speed of the belt, a high-speed motor must be replaced, but because the high-speed motor is expensive, this will increase the equipment cost of the manufacturer; Dust is prone to occur during the process, causing pollution in the factory area

The invention belongs to the technical field of solid material conveying and discloses a foundry sand conveying device. The foundry sand conveying device comprises a pressured vessel. A material inlet is formed in the top of the pressured vessel, and the bottom of the pressured vessel is connected with a discharging pipe. An air inlet is formed in a vessel body of the pressured vessel, and an air filter is installed at the air inlet and connected with an air compressor outside the pressured vessel through an air pipe. A feeding level gage and a discharging level gage are arranged on the upper portion and the lower portion of the vessel body of the pressured vessel sequentially. The lower portion of the pressured vessel is further provided with an exhausting pipe, and the exhausting pipe is provided with an exhausting valve. Compressed air serves as a conveying carrier, and foundry sand is conveyed by means of the characteristic of high-speed flowing of the compressed air. The whole conveying process is completed in the closed vessel body and the closed pipeline, flying dust is avoided, breath safety of workers is protected, and air pollution of a factory is avoided.
Description
technical field [0001] The invention belongs to the technical field of solid material transportation. Background technique [0002] A molding material used to prepare molding sand and core sand in foundry production. In the case of using clay as the sand binder, about 1 ton of new sand needs to be added for every ton of qualified castings produced, so the amount of foundry sand used in sand casting production is the largest. The shape of foundry sand is generally divided into three types. ①Round sand: The particles are spherical or close to spherical, with smooth surface and no prominent edges and corners. ② Polygonal sand: The particles are polygonal, and most of them are obtuse angles. ③Sharp-shaped sand: the particles are pointed-shaped, and there are many sharp angles. [0003] The existing foundry sand needs to go through a series of treatments before it can be used in the foundry process. Now the transportation method of foundry sand is belt transportation. The dis...
