Abstract
Description
Technical Field
[0001] This utility model relates to the field of wool processing pretreatment technology, and in particular to a drying device for wool processing. Background Technology
[0002] Wool is typically sheared from sheep on farms, ranches, and livestock farms, and then transported to textile mills for processing. During transportation and storage, bacteria and mold (such as Pseudomonas and Aspergillus) can easily grow, causing the fibers to rot and produce an unpleasant odor. Furthermore, before washing, wool is covered with 15-25% lanolin, which is prone to hydrolysis and rancidity in humid environments.
[0003] Therefore, it is best to dry the wool after shearing. Hot air dehydration can not only preserve the integrity of lanolin but also prevent lanolin from hydrolyzing and becoming rancid. In addition, 80-100℃ high-temperature hot air can reduce the moisture content of wool to below 15% within 5 minutes, blocking the window period for microbial activity.
[0004] Normally, wool cannot withstand excessively high temperatures, especially above 60℃, which can cause the edges of the wool scales to curl and harden. In addition, wool should not be over-dried during tumble drying. Fortunately, the surface of unwashed raw wool is covered with 15-25% lanolin, which forms a liquid protective film at high temperatures of 80-100℃. This reduces the direct contact of hot airflow with the scale layer, and impurities such as grass clippings and sand (accounting for 30-40% of the raw wool weight) absorb some of the heat, slowing down the temperature of the fiber itself.
[0005] The problem is that when using hot air to dry wool raw materials, the accumulation of wool raw materials makes it difficult for hot air to penetrate into the interior of the wool raw materials, which in turn leads to uneven drying inside and outside the wool raw materials. This can easily cause the outside of the wool raw materials to be overheated and over-dried, while the inside of the wool raw materials is still relatively damp and the microorganisms have not been completely killed. Utility Model Content
[0006] In view of this, the purpose of this utility model is to propose a drying device for wool processing, so as to solve the technical problem that hot air drying in the prior art easily leads to uneven drying inside and outside of wool raw materials.
[0007] To achieve the above objectives, this utility model provides a drying device for wool processing, including a hot drying oven for drying wool raw materials, and the drying device further includes:
[0008] A tray is fixedly connected inside the hot drying oven. The tray has several pieces that divide the inside of the hot drying oven into several hot drying chambers. The bottom tray is located below a hot air chamber, and a hot air box is installed inside the hot air chamber.
[0009] An air inlet pipe and an air extraction pipe are fixedly connected to the back of the hot air oven. The air inlet pipe is connected to the hot air chamber, and the air extraction pipe is provided in multiple sets and is connected to each of the hot air chambers respectively.
[0010] A short air outlet pipe is fixedly connected to the support plate. The short air outlet pipe is connected to the hot air box, and an air outlet is provided on the side wall of the short air outlet pipe.
[0011] Furthermore, the outer end of the air inlet pipe is connected to an external air source, the outer end of the air extraction pipe is connected to an external air extraction machine, and a sponge filter screen is provided at the connection between the air extraction pipe and the hot air box.
[0012] Furthermore, the hot air chamber is also equipped with a sealing slide plate, which is used to seal the connection between the air inlet pipe and the hot air box. The sealing slide plate is slidably connected to the inner wall of the hot air box, and the hot air chamber is also equipped with a lifting motor. The sealing slide plate is fixedly connected to the output shaft of the lifting motor.
[0013] Furthermore, the top of the air outlet short pipe is set as a closed spherical end, and each support plate is provided with several evenly arranged air outlet short pipes.
[0014] Furthermore, the hot air oven is also equipped with a square tube, which is fixedly connected to the inner wall of the hot air oven and the tray. The hot air box is connected to the air outlet short pipe through the square tube.
[0015] Furthermore, the tray is provided with an air flow channel, and the square tube and the short air outlet tube are both connected to the air flow channel in the tray.
[0016] Furthermore, the top of the hot air box is equipped with an inward blower, and the hot air box is also connected to the square tube through a connecting pipe. The blower drives the air to pass through the hot air box, heat it, and then enter the square tube, and finally spray it out through the air outlet on the air outlet short pipe.
[0017] Furthermore, the hot air box is also equipped with a heater, the air inlet of which is connected to a blower, and the air outlet of which is connected to a connecting pipe.
[0018] The beneficial effects of this utility model are as follows: 1. A hot drying oven is set up to dry wool raw materials. The hot drying oven is equipped with a tray for placing wool raw materials. The tray is equipped with several short air outlet pipes. The short air outlet pipes are relatively thin and long, and the top of the short air outlet pipes is set as a closed spherical end. Therefore, when the wool raw materials are placed on the tray, the short air outlet pipes will be inserted into the wool raw materials. Since the air outlet is located on the side wall of the short air outlet pipe, hot air is allowed to enter the wool raw materials and then leave through the wool raw materials, thus achieving drying of the wool raw materials from the inside out and ensuring that the wool raw materials are dried evenly inside and out.
[0019] 2. The hot drying oven is equipped with multiple trays, dividing the interior into several drying chambers, allowing for batch drying of wool raw materials. The bottom tray houses a hot air chamber containing a hot air box, which in turn contains a heater. An inward-facing blower is located at the top of the hot air box. The blower drives air circulation, and the heater then heats the air, ensuring a continuous supply of hot air for drying the wool raw materials. Attached Figure Description

[0032] The first aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, when using hot air to dry wool raw materials, the accumulation of wool raw materials makes it difficult for hot air to penetrate the interior of the wool raw materials, resulting in uneven drying inside and outside the wool raw materials. This easily leads to the wool raw materials being overheated and dried on the outside, while the inside of the wool raw materials is still relatively damp and microorganisms have not been completely killed. Therefore, this utility model designs a hot air drying oven 101 to dry wool raw materials.
[0033] Specifically, a tray 106 is fixedly connected inside the hot oven 101. The tray 106 has several pieces and divides the inside of the hot oven 101 into several hot drying chambers. A hot air chamber 104 is set below the bottom tray 106, and a hot air box 108 is set inside the hot air chamber 104.
[0034] The hot drying oven 101 is equipped with multiple trays 106, which divide the interior of the hot drying oven 101 into several hot drying chambers, allowing for the batch drying of wool raw materials.
[0035] Additionally, a short exhaust pipe 107 is provided on the tray 106, which is connected to the hot air box 108, and an exhaust port 114 is provided on the side wall of the short exhaust pipe 107. A square tube 105 is also provided inside the hot air oven 101, which is fixedly connected to the inner wall of the hot air oven 101 and the tray 106. The hot air box 108 is connected to the short exhaust pipe 107 through the square tube 105.
[0036] Preferably, the top of the air outlet short pipe 107 is a closed spherical end, and each support plate 106 is provided with a number of evenly arranged air outlet short pipes 107.
[0037] A hot drying oven 101 is set up to dry wool raw materials. A tray 1006 is set up in the hot drying oven 101 to place the wool raw materials. The tray 106 is equipped with several air outlet short pipes 107. The air outlet short pipes 107 are relatively thin and long, and the top of the air outlet short pipes 107 is set as a closed spherical end. Therefore, when the wool raw materials are placed on the tray 106, the air outlet short pipes 107 will be inserted into the wool raw materials. Since the air outlet 114 is located on the side wall of the air outlet short pipes 107, hot air enters into the wool raw materials and then passes through the wool raw materials and leaves, realizing the drying of the wool raw materials from the inside out, ensuring that the wool raw materials are dried evenly inside and out.
[0038] The second aspect of this utility model is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in order to ensure the drying effect, a hot air box 108 is provided in the hot air chamber 104. The top of the hot air box 108 is provided with an inward blower 112, and the hot air box 108 is also connected to the square tube 105 through a connecting pipe 113. The blower 112 drives the air to enter the square tube 105 after being heated by the hot air box 108, and finally sprays it out through the air outlet 114 on the air outlet short pipe 107.
[0039] The hot air box 108 is also equipped with a heater 111. The air inlet of the heater 111 is connected to the blower 112, and the air outlet of the heater 111 is connected to the connecting pipe 113.
[0040] In addition, an air inlet pipe 102 and an air extraction pipe 103 are fixedly connected to the back of the hot air oven 101. The air inlet pipe 102 is connected to the hot air chamber 104, while the air extraction pipe 103 is provided in multiple sets and is connected to each of the hot air chambers. The outer end of the air inlet pipe 102 is connected to an external air source, and the outer end of the air extraction pipe 103 is connected to an external air extractor. A sponge filter screen is provided at the connection between the air extraction pipe 103 and the hot air chamber 108.
[0041] To ensure the airtightness of the hot air chamber 104, the inner cavity of the hot air chamber 104 is only connected to the air inlet pipe 102.
[0042] Additionally, a sealing slide plate 110 is provided inside the hot air chamber 104 to seal the connection between the air inlet pipe 102 and the hot air box 108. The sealing slide plate 110 is slidably connected to the inner wall of the hot air box 108, and a lifting motor 109 is also provided inside the hot air chamber 104. The sealing slide plate 110 is fixedly connected to the output shaft of the lifting motor 109.
[0043] A heater 111 is installed inside the hot air box 108, and an inward-facing blower 112 is provided on the top of the hot air box 108. The blower 112 drives the air to circulate, and the heater 111 heats the air, ensuring a continuous supply of hot air to dry the wool raw materials.
[0044] In summary, this utility model uses a hot drying oven 101 to dry wool raw materials. The hot drying oven 101 is equipped with a tray 106 for placing the wool raw materials, and the tray 106 is provided with several short air outlet pipes 107. The short air outlet pipes 107 are relatively thin and long, and the top of the short air outlet pipes 107 is a closed spherical end. Therefore, when the wool raw materials are placed on the tray 106, the short air outlet pipes 107 will be inserted into the wool raw materials. Since the air outlet 114 is located on the side wall of the short air outlet pipe 107, hot air can enter the wool raw materials and then pass through the wool raw materials and leave, thus achieving drying of the wool raw materials from the inside out and ensuring that the wool raw materials are dried evenly inside and out.
[0045] The hot drying oven 101 is equipped with multiple trays 106, dividing the interior into several drying chambers for batch drying of wool raw materials. Below the bottom tray 106 is a hot air chamber 104, which contains a hot air box 108. The hot air box 108 is equipped with a heater 111, and an inward-facing blower 112 is located at the top of the hot air box 108. The blower 112 drives air circulation, and the heater 111 heats the air, ensuring a continuous supply of hot air for drying the wool raw materials.
