Description

Technical Field

[0001] This utility model relates to the field of drying and cooling machine technology, and in particular to a tunnel-type drying and cooling machine. Background Technology

[0002] The tunnel-type drying and cooling machine is a continuous material processing equipment. Its core function is to continuously convey the material to be processed into the tunnel-type closed or semi-closed cavity. First, the heating system is used to uniformly dry the material to remove moisture and meet the drying requirements. Then, the subsequent cooling system quickly cools the dried material to a suitable temperature, ultimately achieving integrated continuous processing from drying to cooling.

[0003] Existing tunnel-type drying and cooling machines often suffer from the problem of material clumping and piling during the feeding stage, resulting in uneven heating of the material after it enters the drying stage and making it difficult to guarantee the drying quality. At the same time, the connection between the drying and cooling stages of some equipment is not smooth enough, and there is a lack of effective buffer structure. The material quality is easily affected by sudden changes in temperature and humidity, making it difficult to adapt to the processing needs of materials of different specifications and states, and inconvenient for users.

[0004] Therefore, a tunnel-type drying and cooling machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a tunnel-type drying and cooling machine that can solve the problem that existing tunnel-type drying and cooling machines often have the problem of material clumping and stacking during the feeding stage, resulting in uneven heating of the material after entering the drying stage and difficulty in ensuring drying quality. At the same time, the connection between the drying and cooling stages of some equipment is not smooth enough, lacks an effective buffer structure, and is easily affected by sudden changes in temperature and humidity, making it difficult to adapt to the processing needs of materials of different specifications and states, and inconvenient for users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tunnel-type drying and cooling machine, comprising a transmission structure, a drying structure fixedly connected to the top of the transmission structure, a transition chamber structure fixedly connected to the right side of the drying structure, a cooling chamber structure fixedly connected to the right side of the transition chamber structure, a lifting frame provided on the left side of the drying structure, a rolling material turning assembly provided at the bottom of the lifting frame, a pre-turning mechanism provided on the left side of the rolling material turning assembly, the pre-turning mechanism comprising a push plate, an inclined plate fixedly connected to the left side of the push plate, and comb teeth fixedly connected to the bottom of the push plate.

[0007] Preferably, a connecting frame is fixedly connected to the bottom of the lifting frame, and the rolling material turning assembly is rotatably connected to the connecting frame.

[0008] Preferably, an output component is fixedly connected to the top of the lifting frame, and a rotating shaft is fixedly connected to the output end of the output component.

[0009] Preferably, an output wheel is fixedly connected to the rear side of the output component, and a belt is wound around the surface of the output wheel.

[0010] Preferably, a driven wheel is fixedly connected to the rear side of the rolling material turning assembly, and the belt is wound around the surface of the driven wheel.

[0011] Preferably, a connecting plate is fixedly connected to the left side of the drying structure, and an electric lifting assembly is fixedly connected to the bottom of the connecting plate. The bottom of the electric lifting assembly is fixedly connected to the top of the lifting frame.

[0012] Preferably, a fixing plate is fixedly connected to the left side of the drying structure, and a sliding rod is fixedly connected to the inner wall of the fixing plate.

[0013] Preferably, a stabilizing plate is fixedly connected to both the front and rear sides of the lifting frame, and the inner wall of the stabilizing plate is slidably connected to the surface of the sliding rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a pre-turning mechanism. During use, the inclined plate fixed on the left side of the push plate realizes the smooth reception and guidance of materials during feeding, avoiding material accumulation and jamming. The comb teeth at the bottom of the push plate can effectively comb and initially disperse the clumps or stacked materials. With the secondary turning of the subsequent rolling turning component, the materials are in a loose and uniform state before entering the drying structure, which greatly increases the contact area between the materials and the drying medium, laying the foundation for uniform drying in the future and improving the efficiency of the feeding and pre-treatment process as a whole. 2. This application provides a stable carrier for the flow of materials in the drying, transition, and cooling stages by setting up a transmission structure, ensuring continuous and smooth material transportation. The drying structure provides a drying operation space for the materials, achieving rapid moisture removal. The fixed transition chamber structure on its right side can effectively buffer the temperature and humidity changes of the materials after drying, avoiding the impact of sudden temperature changes on material quality. The cooling chamber structure can efficiently cool the dried materials to meet the temperature requirements of subsequent processing or storage. (The drying structure adopts the principle of hot air circulation, which achieves heat transfer by introducing hot airflow to fully contact the materials, quickly removing the moisture from the materials to achieve the drying effect. The transition chamber structure forms a relatively closed buffer space, using the natural temperature and humidity gradient inside the chamber to achieve a smooth transition of the materials from the drying state to the cooling state, without the need for additional auxiliary equipment, which is an existing natural transition method. The cooling chamber structure adopts the principle of cold air convection cooling, introducing room temperature airflow to exchange heat with high temperature materials, reducing the material temperature.) The lifting frame can flexibly adjust the position of the rolling turning component according to the material height and turning requirements to ensure drying uniformity. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 The present invention provides the following technical solution: A tunnel-type drying and cooling machine includes a transmission structure 1, a drying structure 3 fixedly connected to the top of the transmission structure 1, a transition chamber structure 4 fixedly connected to the right side of the drying structure 3, a cooling chamber structure 5 fixedly connected to the right side of the transition chamber structure 4, a lifting frame 6 provided on the left side of the drying structure 3, a rolling material turning assembly 7 provided at the bottom of the lifting frame 6, a pre-turning mechanism 2 provided on the left side of the rolling material turning assembly 7, the pre-turning mechanism 2 including a push plate 201, an inclined plate 202 fixedly connected to the left side of the push plate 201, and a comb tooth 203 fixedly connected to the bottom of the push plate 201.

[0019] In this embodiment: By setting up a pre-turning mechanism 2, the inclined plate 202 fixed on the left side of the push plate 201 ensures smooth receiving and guiding of materials during feeding, avoiding material accumulation and jamming. The comb teeth 203 at the bottom of the push plate 201 can effectively comb and initially disperse clumps or stacked materials. Combined with the secondary turning of the subsequent rolling turning component 7, the materials are made into a loose and uniform state before entering the drying structure 3, greatly increasing the contact area between the materials and the drying medium, laying the foundation for subsequent uniform drying, and improving the overall efficiency of the feeding and pre-treatment process. By setting up a transmission structure 1, a stable carrier is provided for the flow of materials in the drying, transition and cooling stages, ensuring continuous and smooth material conveying. The drying structure 3 provides a drying operation space for materials, realizing rapid moisture removal. The transition chamber structure 4 fixed on its right side can effectively slow down the flow of materials. The temperature and humidity changes of the material after drying are minimized to avoid the impact of sudden temperature changes on material quality. The cooling chamber structure 5 can efficiently cool the dried material to meet the temperature requirements of subsequent processing or storage. (The drying structure 3 adopts the principle of hot air circulation, which introduces hot airflow to fully contact the material to achieve heat transfer and quickly remove the moisture from the material to achieve the drying effect. The transition chamber structure 4 forms a relatively closed buffer space and uses the natural temperature and humidity gradient in the chamber to achieve a smooth transition of the material from the drying state to the cooling state. No additional auxiliary equipment is required, which is an existing natural transition method. The cooling chamber structure 5 adopts the principle of cold air convection cooling, which introduces room temperature airflow to exchange heat with high temperature materials to reduce the material temperature.) The lifting frame 6 can flexibly adjust the position of the rolling turning component 7 according to the material height and turning requirements to ensure the uniformity of drying.

[0020] Specifically, such as Figure 4 As shown, a connecting frame 8 is fixedly connected to the bottom of the lifting frame 6, and the rolling material turning assembly 7 is rotatably connected to the connecting frame 8.

[0021] Specifically, such as Figure 5 As shown, an output component 9 is fixedly connected to the top of the lifting frame 6, and a rotating shaft 10 is fixedly connected to the output end of the output component 9.

[0022] Specifically, such as Figure 5 As shown, an output wheel 11 is fixedly connected to the rear side of the output component 9, and a belt 12 is wound around the surface of the output wheel 11.

[0023] In this embodiment: by setting the connecting frame 8, a stable rotating mounting base is provided for the rolling material turning component 7, ensuring smooth and reliable turning action. The output component 9 outputs power through the rotating shaft 10, and with the transmission action of the output wheel 11 and the belt 12, the power is stably transmitted to the rolling material turning component 7, realizing the efficient operation of the turning component, ensuring the secondary turning effect of the material, and improving the uniformity of material dispersion.

[0024] Specifically, such as Figure 5As shown, a driven wheel 13 is fixedly connected to the rear side of the rolling material turning assembly 7, and a belt 12 is wound around the surface of the driven wheel 13.

[0025] Specifically, such as Figure 4 As shown, a connecting plate 14 is fixedly connected to the left side of the drying structure 3, and an electric lifting assembly 15 is fixedly connected to the bottom of the connecting plate 14. The bottom of the electric lifting assembly 15 is fixedly connected to the top of the lifting frame 6.

[0026] In this embodiment: By setting the driven wheel 13, it is easy to drive the driven wheel 13 to rotate through the belt 12, so as to achieve precise power transmission and ensure that the material turning component and the output component 9 operate synchronously. The connecting plate 14 on the left side of the drying structure 3 provides a solid installation support for the electric lifting component 15. The electric lifting component 15 can drive the lifting frame 6 to flexibly adjust the height, accurately adapt to different material heights and material turning requirements, and enhance the adaptability of the equipment.

[0027] Specifically, such as Figure 6 As shown, a fixing plate 16 is fixedly connected to the left side of the drying structure 3, and a slide rod 17 is fixedly connected to the inner wall of the fixing plate 16.

[0028] Specifically, such as Figure 6 As shown, stabilizing plates 18 are fixedly connected to both the front and rear sides of the lifting frame 6, and the inner wall of the stabilizing plate 18 is slidably connected to the surface of the slide rod 17.

[0029] In this embodiment: by setting a fixed plate 16 and a sliding rod 17, the fixed plate 16 provides a stable mounting carrier for the sliding rod 17, and the stabilizing plates 18 on the front and rear sides of the lifting frame 6 slide in cooperation with the sliding rod 17 to provide guidance and limit for the lifting action of the lifting frame 6, avoid deviation and shaking during the lifting process, ensure the stability and accuracy of the lifting adjustment, and further improve the working stability of the rolling material turning component 7.

[0030] Working principle: During the use of the conveyor structure 1, the material is first smoothly received and guided by the inclined plate 202. Simultaneously, the comb teeth 203 at the bottom of the push plate 201 comb and disperse any agglomerated or stacked material, completing the initial pretreatment. The material is then conveyed from the conveyor structure 1 to the drying structure 3, where it is turned over a second time by the rolling turning component 7, forming a loose and uniform state. Upon entering the drying structure 3, the equipment introduces hot airflow through a hot air circulation principle. The hot airflow fully contacts the material, transferring heat and quickly removing moisture to achieve drying. The dried material then enters the transition chamber structure 4, utilizing the internal phase... The natural temperature and humidity gradient formed in the enclosed space completes a smooth transition from the drying state to the cooling state. After the transition, the material continues to enter the cooling chamber structure 5 through the transmission structure 1. The cold air convection principle introduces room temperature airflow to exchange heat with the high temperature material, thereby cooling the material. Throughout the process, the electric lifting component 15 can drive the lifting frame 6 to adjust the height up and down along the slide bar 17 to adapt to the turning requirements of different materials. At the same time, the output component 9 cooperates with the driven wheel 13 through the rotating shaft 10, output wheel 11, belt 12, and driven wheel 13 to stably transmit power to the rolling turning component 7, ensuring that the turning action is continuous and efficient.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
