Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment for succinic acid production, and particularly relates to drying equipment for succinic acid production. Background Technology

[0002] Succinic acid, also known as succinic acid, is an important organic dicarboxylic acid with wide applications in chemical, pharmaceutical, and food industries. Drying is a crucial step in the production of succinic acid, directly impacting product quality and production efficiency.

[0003] Traditional succinic acid drying equipment typically employs a static drying method, where materials are piled on trays or conveyor belts, and hot air is blown across the material surface from a single direction or a limited angle. This results in uneven drying, low efficiency, and a tendency for localized overheating, which can lead to the decomposition of succinic acid. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A drying apparatus for succinic acid production includes a drying chamber and a blowing device. The blowing device is located on both sides and the bottom of the drying chamber. A support plate is provided at the bottom of the drying chamber. The support plate is composed of multiple first support plates and second support plates, which are alternately arranged. The bottom of the multiple first support plates is connected to the same first lifting frame, and the bottom of the multiple second support plates is connected to the same second lifting frame. The first lifting frame and the second lifting frame move upward alternately, causing the material on the first support plates and the second support plates to move upward and be blown down by hot air into the groove formed by the first support plates and the second support plates, thus completing the self-turning of the material.

[0006] As a preferred embodiment of the above technical solution, both the first and second carrier plates are provided with multiple air outlets, and a filter screen is provided at the air outlet position. When the first or second carrier plate moves upward, the air outlet leaks out and blows air into the material in the groove for drying.

[0007] As a preferred embodiment of the above technical solution, the filter is flush with the surface of the air outlet, and the filter screen diameter is smaller than the material diameter.

[0008] As a preferred embodiment of the above technical solution, the gaps between the first and second support plates, between the first support plate and the inner wall of the drying chamber, and between the second support plate and the inner wall of the drying chamber are all smaller than the diameter of the material.

[0009] As a preferred embodiment of the above technical solution, the first lifting frame and the second lifting frame are respectively connected to independent drive devices, wherein the drive devices are hydraulic lifting devices or electric lifting devices.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The support plate is composed of multiple alternating first and second support plates, which are connected to independent first and second lifting frames respectively. By alternating upward movement of the first and second lifting frames, the material is moved upward and fell in a regular manner, which makes the material produce a "self-turning" effect. In addition, during the process of the material being blown down by hot air, its surface is constantly renewed and in contact with the hot air, avoiding the problem of insufficient drying caused by local accumulation, and helping to improve the uniformity of product drying.

[0012] 2. When the first or second support plate moves upward, the side air outlet leaks out to blow air into the material in the groove. The blowing equipment at the bottom and sides further enhances the flow of hot air, realizing all-round and dead-angle drying of the material, making up for the defects of uneven drying by traditional single-sided or local blowing.

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0018] Figures 1-3 The drying device for succinic acid production includes a drying chamber 10 and a blowing device 20. The blowing device 20 is located on both sides and the bottom of the drying chamber 10. A support plate is provided at the bottom of the drying chamber 10. The support plate is composed of multiple first support plates 31 and second support plates 41. The first support plates 31 and second support plates 41 are alternately arranged. The bottom of the multiple first support plates 31 is connected to the same first lifting frame 32. The bottom of the multiple second support plates 41 is connected to the same second lifting frame 42. The first lifting frame 32 and the second lifting frame 42 move upward alternately, so that the material on the first support plates 31 and the second support plates 41 moves upward and is blown down by hot air into the groove formed by the first support plates 31 and the second support plates 41, thus completing the self-turning of the material.

[0019] The gaps between the first support plate 31 and the second support plate 41, between the first support plate 31 and the inner wall of the drying chamber 10, and between the second support plate 41 and the inner wall of the drying chamber 10 are all smaller than the diameter of the material.

[0020] The support plate is composed of multiple alternating first support plates 31 and second support plates 41, which are respectively connected to independent first lifting frames 32 and second lifting frames 42. By alternating upward movement of the first lifting frames 32 and second lifting frames 42, the material is moved upward and fell in a regular manner, which makes the material produce a "self-turning" effect. In addition, during the process of the material being blown down by hot air, its surface is constantly renewed and in contact with the hot air, avoiding the problem of insufficient drying caused by local accumulation, and helping to improve the uniformity of product drying.

[0021] Figures 2-3 In the process, the first support plate 31 and the second support plate 41 are each provided with a plurality of air outlets 50, and a filter screen 60 is provided at the position of the air outlet 50. When the first support plate 31 or the second support plate 41 moves upward, the air outlet 50 leaks out and blows the material in the groove to dry it.

[0022] The filter is flush with the surface of the air outlet 50, and the diameter of the filter screen 60 is smaller than the diameter of the material.

[0023] When the first support plate 31 or the second support plate 41 moves upward, the side air outlet 50 leaks out to blow air into the material in the groove. The blowing equipment 20 at the bottom and on both sides further enhances the flow of hot air, so as to achieve all-round and dead-angle drying of the material, which makes up for the defects of uneven drying by traditional single-sided or local blowing.

[0024] The first lifting frame 32 and the second lifting frame 42 are respectively connected to independent driving devices, which are hydraulic lifting devices or electric lifting devices.

[0025] Working principle: When using this succinic acid production drying device, the material to be dried is first placed on the support plate composed of the first support plate 31 and the second support plate 41. Then, the drive device is started, causing the first lifting frame 32 and the second lifting frame 42 to move up intermittently and alternately. The first support plate 31 and the second support plate 41 rise alternately. When the first support plate 31 rises, the air outlets 50 on both sides of it leak out. The blowing devices 20 on both sides of the drying chamber 10 and the air jet nozzles at the bottom blow air into the material in the groove for drying. Under the action of hot air, the material is blown up and falls into the groove formed by the second support plate 41 and the first support plate 31. Similarly, when the second support plate 41 rises, the material is blown down into the groove formed by the first support plate 31 and the second support plate 41. This process is repeated to achieve continuous turning and drying of the material.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
