Description

Technical Field

[0001] The utility model belongs to the field of needle-punched filter material processing, and relates to a needle-punched filter material processing device. Background Technique

[0002] Needle-punched filter material is one of the necessary materials in filter materials. Needle-punched filter material originated in the 1950s. Due to the advantages of simple process flow, fast production speed, low cost, and easy process variation, it is widely used worldwide. Now, the varieties have developed from the original polyester needle-punched filter material to needle-punched filter materials that can use a variety of raw materials, have a variety of uses, and various specifications.

[0003] During the production process, heat setting treatment needs to be carried out on the needle-punched filter material. Heat setting means heating the needle-punched filter material to fix the material form through heat impregnation, heat setting, etc., and adjusting parameters such as its air permeability and strength. This step is to ensure the use effect and quality of the needle-punched filter material. However, the hot air in the existing heat setting device will be directly discharged through the material passing port or exhaust port opened on it. The hot air still retains heat after setting the composite material and is directly discharged to the outside, resulting in energy waste. Content of the Utility Model

[0004] The purpose of the utility model is to aim at the deficiencies of the prior art and propose a needle-punched filter material processing device, which is used to solve the technical problem that the prior art cannot recycle the hot air with remaining heat after setting the composite material, resulting in energy waste mentioned in the background technique.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A needle-punched filter material processing device includes a box body. Through holes are opened at both the front and rear ends of the box body. Two symmetrically arranged partition plates are fixed inside the box body. The two partition plates divide the inner cavity of the box body into two circulation cavities and a setting cavity. The setting cavity is located between the two circulation cavities. Two symmetrically arranged traction rollers are rotatably installed between the two partition plates. A support frame is fixed inside the box body and is located below the two traction rollers in the setting cavity. A plurality of heating lamps are fixed on the support frame. A motor is fixed at the top of the support frame. The output shaft of the motor is fixed with a plurality of extraction fan blades. The partition plates are provided with two ventilation openings communicating the setting cavity and the circulation cavities. The two ventilation openings are respectively located above the traction rollers and below the support frame. An extraction air pipe communicating with the setting cavity and located below the support frame is fixed at one end of the box body.

[0007] Working Principle:

[0008] The needle-punched filter material is pulled by two traction rollers and enters the shaping cavity through the material passing opening. The driving motor drives the exhaust fan blade to rotate, and draws in the outside air through the exhaust air pipe. The heating lamp is started, and the air entering the interior of the box is heated by the heating lamp, thereby realizing the heating and shaping treatment of the filter material. The hot air after the heating treatment of the filter material enters the two circulation cavities respectively through the two ventilation openings located at the upper end. The hot air in the circulation cavity enters the shaping cavity through the two ventilation openings at the lower end, thereby realizing the preheating of the cold air entering the shaping cavity, and thus realizing the energy saving.

[0009] The beneficial effects of the present utility model are as follows:

[0010] In the present utility model, by providing two partition plates and a motor, the driving motor drives the exhaust fan blade to rotate, so that the hot air with heat in the shaping cavity enters the circulation cavity through the ventilation opening located at the upper end, and the hot air in the circulation cavity enters the shaping cavity through the ventilation opening located at the lower end, effectively reducing the direct discharge of the hot air, and realizing the preheating of the cold air entering the shaping cavity, thereby realizing the energy saving and improving the shaping efficiency.
