technical field

The utility model belongs to the technical field of cashmere machinery, in particular to a radio frequency drying device for cashmere which is used for drying after preliminary sorting and washing.

Background technique

After washing, the raw cashmere is dehydrated and dried, and then enters the subsequent fine sorting and opening processes. At present, the drying process often uses high-temperature steam to dry dehydrated cashmere. This method has the characteristics of high efficacy and good drying effect; but because cashmere is highly sensitive to temperature, when the steam temperature exceeds 80 degrees Celsius, It will cause damage to the cashmere fiber; and it is difficult to realize the precise control of the steam temperature in the production process. In order to overcome the defect that steam drying has strict temperature requirements, the drying process is completed by radio frequency technology; however, due to the defect of poor penetration of radio frequency, the thickness of cashmere is greatly limited when drying cashmere, resulting in It solves the problem that the drying efficiency is low and it is difficult to meet the needs.

detailed description

The structure and operating principle of the cashmere radio frequency drying device provided by the utility model will be further described in detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 , it is a structural schematic diagram of a cashmere radio frequency drying device provided by the utility model. The structure that constitutes this device comprises the hair feeding mechanism 2 after the washing process 1 and the radio frequency drying mechanism 3 that is provided with the conveyor belt mechanism; a pre-drying mechanism 4 is arranged between the two; the pre-drying mechanism consists of first and second Two juxtaposed mesh drums 52, 62 fixed by rotating shafts 51, 61, fan mechanisms 53, 63 arranged on the sides of the two mesh drums, and baffles arranged on the lower side of the two mesh drums Wind board forms 54,64 and forms.

Its working principle is as follows: first start the power system, and the fan mechanism draws or blows air to form a negative pressure in the rotating mesh drum; the raw cashmere after washing is evenly transported to the first mesh drum by the wool feeding mechanism, because the drum The inside is in a negative pressure state, and the raw cashmere is attached to the rotating surface, and its moisture is taken away with the negative pressure airflow in the drum. With the function of the wind plate, the negative pressure will be released on the surface of the first drum at the junction, and the raw cashmere will automatically transfer to the second mesh drum that has formed a negative pressure, and continue to be carried by the same negative pressure airflow. go, thereby forming raw cashmere with relatively low moisture content; the raw cashmere is introduced into the transmission mechanism of the radio frequency dryer through the hair guide plate 7, and the drying is completed. Since the moisture content of the pre-dried raw cashmere is relatively low, it will be in a relatively fluffy state compared with the raw cashmere that has just been washed, which increases the thickness of the raw cashmere on the radio frequency drying conveyor belt. Greatly improved the efficiency of radio frequency drying.

In the structure that constitutes the above-mentioned cashmere radio frequency drying device,

——In order to further improve the efficiency of the fan, and to enable smooth cashmere transfer between two adjacent mesh drums, the windshields 54 and 64 in the drum are set at one-third to two-thirds of the inner circumference of the drum. At the same time, the rear end 541 of the first windshield 54 at the junction of the two is higher than the front end 641 of the second windshield 64, so that the cylinder surface of the first drum at the junction will release the negative pressure, The raw cashmere will automatically transfer to the second mesh drum that has formed a negative pressure.

Of course, the mesh drums constituting the above-mentioned pre-drying mechanism can be set to one or three to more; The transfer of cashmere between cylinders is smoother.

As shown in FIG. 2 , it is a schematic structural diagram of the second cashmere radio frequency drying device provided by the present invention.

The partition plate 45 of the tube tube 44 is provided with a blower mechanism 5 at the side of the tube tube, or is provided with a connecting tube 10 at the end of the adjacent tube tube so that the above-mentioned tube tubes are preferably connected in series wind tunnel.

Its working principle is as follows: first start the power system, and the fan mechanism draws air to form a negative pressure in the tube formed by the rotating conveyor belt and the partition; the raw cashmere after washing is evenly transported to the mesh conveyor belt by the wool feeding mechanism; Because the inside of the tube is in a negative pressure state, the raw cashmere is attached to the rotating surface, and its moisture is taken away with the negative pressure airflow in the tube. Raw cashmere with low moisture content; the raw cashmere is introduced into the transmission mechanism of the radio frequency dryer through the hair guide plate 7, and the drying is completed. Since the moisture content of the pre-dried raw cashmere is relatively low, it will be in a relatively fluffy state compared with the raw cashmere that has just been washed, which increases the thickness of the raw cashmere on the radio frequency drying conveyor belt. Greatly improved the efficiency of radio frequency drying.

——In order to further improve the efficiency of the fan, a baffle 46 is provided at the bottom of the above tube to form a U-shaped structure with an upper opening;
