Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to a conveying mechanism and a belt dryer. Background Art

[0002] The belt dryer is a continuous drying device designed for drying highly permeable flake, strip, or granular materials. It is particularly suitable for materials with high moisture content that cannot be heated to high temperatures. It offers the advantages of fast drying speed, high evaporation intensity, and excellent product quality. During drying, the material is spread on a conveyor belt and moved through the dryer by a transmission mechanism. A heating mechanism is located beneath the conveyor belt, and the heat generated by the heating mechanism passes through the conveyor belt to dry the material.

[0003] In traditional belt dryers, the conveyor belt is corrected using built-in positioning sensors. These sensors provide feedback to the PLC, which then controls cylinders at the ends of the conveyor belt to adjust the belt. However, in highly corrosive environments, such as those involving hydrogen fluoride, neither the sensors nor the cylinders can function properly. Utility Model Content

[0004] In view of this, the purpose of the present application is to provide a conveying mechanism and a belt dryer with a simple and reliable structure and suitable for highly corrosive environments.

[0009] In a preferred embodiment, a gap is formed between the connecting member and the conveyor belt, and the conveying mechanism further includes a protective member, which covers the gap.

[0010] In a preferred embodiment, the protective member includes a protective cover, which covers the connecting member and is connected to the conveyor belt to cover the gap.

[0011] In a preferred embodiment, the protective cover and the conveyor belt are both made of cloth and are sewn together.

[0030] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0032] Reference Figure 1-Figure 4 As shown, an embodiment of the present application discloses a conveying mechanism 100 , which includes a conveyor belt 10 , two transmission components 20 and a connecting member 30 .

[0033] The two transmission components 20 are respectively arranged on both sides of the conveyor belt 10. The transmission components 20 include a guide rail 21 and a moving part 22. The guide rail 21 limits the moving direction of the moving part 22. The moving part 22 is connected to the conveyor belt 10 to drive the conveyor belt 10 to move synchronously. The two ends of the connecting part 30 are respectively connected to the moving parts 22 in the two transmission components 20.

[0034] Among them, in traditional conveying mechanisms, the transmission components on both sides of the conveyor belt are usually independent. After long-term research, the inventors found that during the movement of the conveyor belt, the pulling force of the conveyor belt on the transmission components on both sides is usually different and may change dynamically. Therefore, the transmission component on the side with greater pulling force may shrink toward the center, causing deviation and derailment.

[0035] In one embodiment, the moving direction of the moving member 22 is limited by the extension direction of the guide rail 21. For example, the guide rail 21 is long and the moving member 22 moves in a straight line. In another embodiment, the moving direction of the moving member 22 is limited by the shape of the guide rail 21. For example, the guide rail 21 is circular or elliptical and the moving member 22 moves in a circumferential direction. There is no specific limitation.

[0036] Furthermore, the connecting member 30 is disposed above the conveyor belt 10 , or the connecting member 30 is disposed below the conveyor belt 10 , which is not specifically limited.

[0037] The conveying mechanism 100 provided herein is connected to the movable members 22 of the two transmission assemblies 20 via connectors 30, ensuring that the movable members 22 on either side of the conveyor belt 10 always operate on their respective guide rails 21. This prevents the movable members 22 from retracting toward the center under the tension of the conveyor belt 10, causing deviation and derailment. This effectively implements the deviation correction function, has the advantages of a simple structure and low cost, and avoids the use of sensors and cylinders, making it suitable for highly corrosive environments.

[0038] Please continue to refer to Figure 1 As shown, in one embodiment, a gap 40 is formed between the connecting member 30 and the conveyor belt 10. Since smaller materials may accumulate in the gap 40, the conveying mechanism 100 in this embodiment also includes a protective member, which covers the gap 40 and can effectively prevent materials from accumulating in the gap 40.

[0039] Please continue to refer to Figure 2 and 3As shown, in one embodiment, the protective member includes a protective cover 50, which covers the connector 30 and is connected to the conveyor belt 10 to cover the gap 40. Specifically, the protective cover 50 directly covers the connector and is then connected to the conveyor belt 10, forming an integral part of the conveyor belt 10. The protective cover 50 can support material, prevent it from contacting the connector 30, and more directly prevent it from falling into the gap 40, thereby better preventing material accumulation. In other embodiments, the protective member can be other structures capable of covering the gap, such as guardrails, protective nets, etc.

[0040] Please continue to refer to Figure 2 and 3 As shown, in one embodiment, the protective cover 50 and the conveyor belt 10 are both made of fabric and sewn together. The fabric of the conveyor belt 10 facilitates heat transfer through the conveyor belt 10 to dry the material, and the fabric of the protective cover 50 facilitates sewing to the conveyor belt 10. The sewing connection between the protective cover 50 and the conveyor belt 10 effectively prevents material from entering the gap 40. Furthermore, after being connected to the conveyor belt 10, the protective cover 50 and the conveyor belt 10 form a single unit, thereby better achieving the material feeding function.

[0041] Reference Figure 2 As shown, in one embodiment, the conveying mechanism 100 includes a plurality of connectors 30. The connectors 30 are spaced apart along the conveying direction of the conveyor belt 10 (e.g., the X direction in the figure). The connectors 30 cooperate with each other to ensure that the moving members 22 on both sides of the conveyor belt 10 always run on their respective guide rails 21, preventing deviation and derailment, and further ensuring the corrective effect. Specifically, the number of connectors 30 can be 2, 3, 4, 6, 8, etc.

[0042] In one embodiment, the connecting member 30 is hollow. The hollow structure ensures that the connecting member 30 has a high structural strength, while preventing the connecting member 30 from being too heavy, thereby effectively reducing costs.

[0043] In one embodiment, the ends of the connecting member 30 are flattened and provided with connecting holes. The connecting member 30 is connected to the movable member 22 via fasteners 60 that pass through the connecting holes. This ensures the stability of the connection between the connecting member 30 and the movable member 22 and prevents it from falling off during use. Specifically, the fasteners 60 can be rivets or bolts. Alternatively, the connecting member 30 is a stainless steel bright tube. In other embodiments, the connecting member 30 is a plate-like structure or a solid rod-like structure.

[0044] In another embodiment, the connecting member 30 is hollow, with both ends of the connecting member 30 flattened and provided with connecting holes, and the connecting member 30 is connected to the moving member 22 via fasteners 60 passing through the connecting holes. The hollow structure facilitates flattening the ends of the connecting member 30 and facilitates processing.

[0045] Please continue to refer to Figures 1 to 3 As shown, in one embodiment, the movable member 22 includes two groups of chain plates 221 arranged relative to each other, and some of the chain plates 221 in the two groups of chain plates 221 are bent toward the side where the connecting member 30 is located to form ear plates 222, and the connecting member 30 and the conveyor belt 10 are both connected to the ear plates 222. Among them, by bending the chain plates 221 to form the ear plates 222, it is avoided to separately set up ear plates or other connecting structures, and the structure is simpler, and the structural strength is greater and the stability is better. Furthermore, the connecting member 30 and the conveyor belt 10 can be connected to the ear plates 222 by the same fastener 60. Among them, the movable member 22 is formed by chain deformation, or is formed by other structures that can cooperate with the guide rail 21 to achieve movement, such as a slide.

[0046] In one embodiment, the connector 30 and the conveyor belt 10 are respectively connected to opposite surfaces of the lug plate 222. Specifically, the connector 30 is connected to the top surface of the lug plate 222, while the conveyor belt 10 is connected to the bottom surface of the lug plate 222, further ensuring connection stability. Furthermore, a polytetrafluoroethylene pad 70 is installed between the conveyor belt 10 and the lug plate 222 to ensure connection stability and structural strength.

[0047] Reference Figure 4 As shown, in one embodiment, the guide rail 21 includes an upwardly protruding guide portion 211, and the movable member 22 is provided with a guide groove 223, wherein the guide portion 211 is at least partially located in the guide groove 223, wherein the guide portion 211 cooperates with the guide groove 223 to limit the movement of the movable member 22 along the length direction of the guide rail 21, which has the advantages of simple structure and low cost. Optionally, the guide rail 21 is a long metal strip with a protruding portion, and is made of a wear-resistant and highly lubricating material.

[0048] Reference Figure 5 As shown, based on the same inventive concept, another embodiment of the present application further provides a belt dryer, which includes the conveying mechanism 100 in the above embodiment and also includes a heating mechanism, which is arranged under the conveyor belt 10 and is used to heat and dry the material on the conveyor belt 10.

[0049] During drying, materials are placed on the conveyor belt 10 and moved through the dryer by a transmission mechanism. Heat generated by a heating mechanism beneath the conveyor belt 10 passes through the conveyor belt 10, heating and drying the materials. Furthermore, the heating mechanism includes a heating plate 210, through which a heating medium flows. The conveyor belt 10 moves against the heating plate 210, enhancing the drying effect.

[0050] The conveying mechanism 100 of the belt dryer in this embodiment can effectively correct the deviation of the conveyor belt 10 and has the advantages of simple structure and low cost. At the same time, it avoids the use of sensors and cylinders and can adapt to highly corrosive environments.
