Technical field:
The utility model belongs to the field of dehumidification and drying machines, in particular to a valveless air cutting device of a conveying integrated dehumidification and drying machine.
Background technique:
In the plastic molding system, the air dehumidification dryer is used to absorb moisture in the air and produce dry air to process plastic raw materials to improve the quality of plastic products. With the widespread application of plastic products and the increasing number of plastic product manufacturers, the requirements for air dehumidification dryers are getting higher and higher, and conveying integrated dehumidification dryers have also emerged. The suction device of the existing conveying integrated dehumidification dryer is mainly composed of a feeding fan and a conveying filter. A cut-off valve is installed on the raw material barrel. When the suction is completed, the cut-off valve is closed and the feeding fan stops working. In order to prevent the raw material from remaining in the suction hose and cause blockage, the one-way shutoff valve is generally controlled by a cylinder. The huge force of the cylinder often crushes the raw material that just moves to the position of the one-way shutoff valve. It also has a certain temperature and is easy to stick to the outlet pipe of the raw material barrel, which affects the completion of the next suction work, and even causes blockage. If you want to clean up, you must disassemble the machine, which not only wastes raw materials, but also consumes A lot of manpower. Riveting The purpose of the utility model is to provide a valveless air cutting device of a conveying integrated dehumidification dryer that can solve the above-mentioned problems and will not cause blockage after the suction is completed. In order to achieve the above purpose, the technical solution adopted by the present utility model is a valveless air cut-off device for conveying an integrated dehumidification dryer, which mainly includes a raw material barrel, a drying electric heater, a drying fan, a dehumidification runner, a regeneration fan, The dehumidification and drying device composed of regenerative electric heater, filter and cooler are connected in order by hoses. The raw material barrel is equipped with a hopper; a conveying device composed of a feeding fan, a conveying filter and a storage barrel. The pipe is connected to the conveying filter. The conveying filter is connected to the storage barrel and the hopper on the raw material barrel through a three-way valve, and the raw material barrel is connected to the storage barrel through a hose; its characteristic is that the feeding fan and the conveying The hose connected to the filter is equipped with a branch pipe, and the branch pipe is equipped with a three-way valve. The other two ends of this three-way valve are connected to the outside world, and the other end is connected with a second-hand valve. One hand valve is directly connected to the raw material barrel and the storage barrel. The connected hose is connected, and the other hand valve is equipped with a three-way valve. One end of the three-way valve is connected to the hose connecting the raw material barrel and the storage barrel, and the other end is connected to the dehumidifying and drying device. After adopting the above structure, when in use, the raw material is dehumidified and dried by a dehumidifying and drying device consisting of a raw material barrel, a drying electric heater, a drying fan, a dehumidifying wheel, a regeneration fan, a regeneration electric heater, a filter and a cooler, and the raw material is dehumidified and dried. After the feeder fan works, the gas is delivered to the hopper of the raw material barrel through the transmission filter connected to it, and the gas is sent into the storage barrel through the raw material barrel through the hose connected to the raw material barrel. The raw materials inside are fed into the storage barrel through the hose. When the feeding is completed, open the two hand valves on the three-way valve on the branch pipe of the hose connected to the feeding fan and the conveying filter, and the gas passes through the two hand valves. At the same time, it is injected into the hose connecting the raw material barrel and the storage barrel, and a gas partition is formed in the hose to stop the continuous input of raw materials from the raw material barrel to the storage barrel. The three-way valve connected to one of the hand valves feeds the gas through the end connected to the dehumidification and drying device into the dehumidification and drying device due to the loss of gas during the dehumidification and drying, so that the next dehumidification and drying can be performed. Because the air cut-off method is used, it will not cause damage to the raw materials, avoid the waste of raw materials, and will not cause the blockage of the raw materials in the machine during the cutting.
This is the working principle diagram of the utility model.
