Description

Technical Field

[0001] This application relates to the technical field of drying devices, and particularly to a uniform air distribution type felt drying device. Background Art

[0002] Existing felt drying devices usually adopt a single-line conveying design, thus only enabling one-sided conveying and drying of the felt. For this reason, it is also necessary to turn the felt over and then convey and dry it again; moreover, the drying air flow of the felt often directly blows onto the surface of the felt, resulting in uneven heat distribution, and further causing some parts not to be sufficiently dried, while other parts are damaged by heat due to excessive exposure to the heat source. Summary of the Utility Model

[0003] The problem to be solved by this application is that existing drying devices usually can only perform one-sided conveying and drying of the felt, and due to the direct blowing of the drying air flow, the heat distribution on the surface of the felt is uneven, and it is easy to occur that some parts are not dried, while other parts are overheated and damaged.

[0004] To solve the above technical problems, this application provides a uniform air distribution type felt drying device, which includes a frame for support. Above the frame, there is a conveyor belt for conveying the felt. Above the conveyor belt, there is a drying assembly for performing air-blowing drying operation on the felt. Below the drying assembly, there is a uniform air distribution assembly for dispersing the air flow to achieve uniform distribution. The number of conveyor belts is two, which are arranged parallel and spaced up and down, and the conveying directions of the two conveyor belts are opposite.

[0005] Since the drying device of this application is designed with a drying assembly, a uniform air distribution assembly and a conveyor belt, therefore, it can not only realize the uniform air flow drying operation of the felt through the drying assembly and the uniform air distribution assembly, but also realize the turning-over drying operation of the felt through the two conveyor belts, solving the problem that existing drying devices usually can only perform one-sided conveying and drying of the felt, and due to the direct blowing of the drying air flow, the heat distribution on the surface of the felt is uneven, and it is easy to occur that some parts are not dried, while other parts are overheated and damaged.

[0016] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. Embodiment

[0017] The present application relates to a felt drying device with uniform air distribution, as Figures 1-9 shown. The drying device includes a rack 3 for support, and casters 4 for walking are respectively arranged around the bottom of the rack 3, so as to facilitate the transfer operation of the drying device. A conveyor belt 2 for conveying felt is arranged on the upper part of the rack 3, and a drying component 1 for blowing air to dry the felt is arranged above the conveyor belt 2. In order to avoid the situation that the air flow blows directly onto the surface of the felt and causes uneven heat distribution, therefore, an air distribution component 5 for dispersing the air flow to achieve uniform distribution is arranged below the drying component 1. In order to enable synchronous drying operations on both sides of the felt to save the drying time of the felt, therefore, the number of conveyor belts 2 is two, which are arranged in parallel and spaced up and down, and the conveying directions of the two conveyor belts 2 are opposite, so that the felt can be turned over and dried on the upper part of the conveyor belt 2 in the lower position.

[0018] The drying component 1 includes a box body, a heating wire 7, a motor 8, an impeller 12, a shaft rod, and a wind hood 9. The box body is arranged directly above the frame 3. According to different functions and arrangement positions, the box body is divided into an inner box 10 and an outer box 6 that are concentrically nested. On one side of the outer box 6, there is a heating wire 7 arranged horizontally inside the inner box 10 to provide heat. The shape of the heating wire 7 can be adaptively designed according to the internal dimensions of the inner box 10. At the positions corresponding to the heating wire 7 in the upper parts of the inner box 10 and the outer box 6, there are air inlets 11. In order to enable the air entering through the air inlets 11 to carry heat and flow in a directional manner, symmetrically arranged on the outer side of the inner box 10 perpendicular to the heating wire 7 are impellers 12 that function as air extraction. And on the outer side of the outer box 6, there is a motor 8 that drives the impeller 12 to rotate through the shaft rod. Thus, the motor 8 drives the impeller 12 to rotate through the shaft rod, so that the air entering the inner box 10 along the air inlets 11 is heated by the heating wire 7 and then immediately extracted by the impeller 12 into the inner part of the outer box 6. A wind hood 9 with a downward opening is added outside the air inlets 11.

[0019] The air distribution component 5 includes an air box and an air duct 13. The number of air boxes is three, which are divided into an upper box 14, a middle box 15, and a lower box 16 according to different arrangement positions. The upper box 14 is arranged above the upper conveyor belt 2, the middle box 15 is arranged inside the upper conveyor belt 2, and the lower box 16 is arranged below the upper conveyor belt 2. And on one side of the air box, there is also an air duct 13 used to communicate with the outer box 6, so that the hot air inside the outer box 6 can be blown into the air box along the air duct 13. In order to enable the hot air to be evenly blown onto the felt surface, the air box is a hollow structure, and the bottom is evenly provided with through holes through which the hot air can be blown out. Compared with the large-diameter notch ventilation structure, the design of the through holes can effectively disperse the hot air evenly. The size of the through holes is 2 - 10 mm.

[0020] The conveyor belt 2 is a mesh conveyor belt 2 so that the air flow can fully contact the felt through the mesh holes on its upper part.

[0021] In order to reduce the natural loss of heat during the drying process of the felt, a sheet metal is coated on the outer side of the conveyor belt 2 to reduce heat loss.

[0022] In use, the felt adopts a U-shaped running track, enters from one end of the upper conveyor belt 2, and then exits from the corresponding position of the lower conveyor belt 2, so that the felt completes the turning operation between the two conveyor belts 2. At the same time, by driving the impeller 12 to rotate with the motor 8, the air that enters the inner box 10 along the air inlet 11 and is heated by the heating wire 7 can be extracted into the outer box 6, and then enters the upper box 14, the middle box 15 and the lower box 16 along the air duct 13. Then, the hot air is evenly dispersed through the air box and finally blown to the upper and lower surfaces of the felt on the upper part of the mesh conveyor belt 2 through the through holes, so that not only the upper and lower surfaces of the felt can be dried simultaneously, but also the air flow can be evenly blown onto the surface of the felt, so that the felt can be evenly dried.

For example, at least in part depending on the context, the term "one or more" used in the text can be used to describe any feature, structure or property with a singular meaning, or can be used to describe a combination of features, structures or properties with a plural meaning. Similarly, at least in part depending on the context, terms such as "a" or "the" can also be understood to convey a singular usage or a plural usage.
