Problems solved by technology

[0003] Traditional extruders are equipped with a dehumidification system for each machine. At the same time, due to the small size of the material storage filter box in the dehumidification system, frequent cleaning is often required. Using this traditional dehumidification system, there is The following fatal shortcomings: 1. Each machine is equipped with a dehumidification system, which consumes a lot of energy; 2. When there are many extrusion machines, the noise generated by the dehumidification system is also very large; 3. Frequent cleaning of filter storage Material bins, resulting in frequent defective products and low production efficiency

Embodiment Construction

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1-3As shown, the vacuum dehumidification and filtration system of the extruder includes a vacuum pump 1, and the vacuum dehumidification and filtration system also includes a suction pipe 2 for communicating with a plurality of extruders at the same time and two filter storage materials for collecting powder materials. Tank 3, filter storage tank 3 and vacuum pump 1 are existing equipment, and the air extraction pipe 2 can be communicated with the inner cavities of the two filter storage tanks 3 through the middle section of the horizontal pipe one 4 at the same time, and each filter storage tank 3 is connected to the horizontal pipe. A control valve 5 for controlling the communication state of the horizontal pipe 1 4 and a s...

Abstract

The invention provides a vacuum dehumidifying and filtering system of an extruder, and belongs to the technical field of extrusion production equipment. The technical problem that an existing dehumidification system of the extruder hinders continuous work of the extruder is solved. The vacuum dehumidifying and filtering system of the extruder comprises a vacuum pump, and further comprises an exhaust pipe used for being communicated with the extruder and a plurality of filtering storage tanks used for collecting powder, and the exhaust pipe can be communicated with inner cavities of the storage tanks at the same time through a first transverse pipe; a first control valve used for controlling the communication state of the first transverse pipe and the single filtering material storage tank is arranged between each filtering material storage tank and the first transverse pipe, the top of each filtering material storage tank is connected with an exhaust pipe, and the exhaust pipes can be communicated with the vacuum pump at the same time. Continuous material receiving and filtering are guaranteed, and the working state is continuous and stable.

Description

technical field [0001] The invention belongs to the technical field of extrusion production equipment, and relates to a vacuum dehumidification filtering system of an extruder. Background technique [0002] The production of pipes requires an extruder to process and form. During the extrusion process, it is necessary to continuously add materials to be plasticized by a screw, and then extruded through a die. In the process of processing, the materials often contain small molecular substances such as water vapor. If they are not discharged during the plasticization process, the performance and appearance of the product will be seriously affected. Therefore, a vacuum dehumidification system is often equipped in extrusion equipment. [0003] The traditional extruder is equipped with a dehumidification system for each machine. At the same time, due to the small volume of the storage filter box in the dehumidification system, frequent cleaning is often required. Using this tradi...
