Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and specifically to a spiral vibration drying device. Background Technology

[0002] Aniline acetonitrile is an important intermediate in the fine chemical industry, and its quality directly affects the synthesis efficiency and quality of subsequent products. According to the current industry standard HG / T 5285-2017, the moisture content of qualified aniline acetonitrile must be strictly controlled below 3%. However, current production processes commonly suffer from a technical defect where the product moisture content is too high, leading to color differences in aniline acetonitrile and severely impacting its grade and market acceptance.

[0003] To address the aforementioned issues, existing technologies generally employ two methods for drying aniline acetonitrile: vacuum disc drying and vibrating fluidized bed drying. However, vacuum disc drying cannot guarantee that the moisture content of aniline acetonitrile after each drying process is below 3%, resulting in insufficient reliability and unsatisfactory drying effects. While vibrating fluidized bed drying can reduce the moisture content of aniline acetonitrile to below 3%, it suffers from poor drying uniformity and unpredictable moisture fluctuations, failing to meet the requirements for continuous and stable production. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a spiral vibration drying device to solve the problems of insufficient reliability, unsatisfactory drying effect and poor drying stability in the drying of p-aniline acetonitrile in the prior art.

Detailed Implementation

[0026] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0027] like Figure 1As shown, an embodiment of the present invention provides a spiral vibration drying device, comprising: a tank body 1, with a discharge port 11 on one side of its lower part; a drying assembly, which is vertically disposed inside the tank body 1, the heating end of the drying assembly extending from the bottom of the tank body 1 for connection to an external heat source; a vibrating feeding assembly, which includes a spiral feeding component slidably sleeved on the outside of the drying assembly and a vibrating component disposed at the bottom of the spiral feeding component, the spiral feeding component being arranged from top to bottom along the circumference of the drying assembly, the discharge end of the spiral feeding component freely passing through the discharge port 11; and an elastic support assembly, which is disposed between the spiral feeding component and the inner wall of the bottom of the tank body 1; wherein a plurality of support legs 12 are fixedly installed on the bottom of the tank body 1 along its circumference to provide stable support for the tank body 1.

[0028] During the feeding process of aniline acetonitrile along the spiral feeder, it is thoroughly and evenly dried by the drying component. After drying, it is discharged from the discharge port 11 into the tank 1. The operation is simple and convenient, ensuring that aniline acetonitrile can be dried continuously and stably, with good drying effect and drying reliability.

[0029] like Figure 1-3 As shown, according to another embodiment of the present invention, the spiral vibration drying device further optimizes the spiral feeding component and the vibrating component. The spiral feeding component includes a vertically arranged feeding cylinder 3 and a spiral material plate 31 fixedly installed inside the feeding cylinder 3 along its axial direction. The discharge end of the spiral material plate 31 passes through the side wall of the feeding cylinder 3 and freely exits through the discharge port 11. The feeding cylinder 3 and the spiral material plate 31 are both slidably sleeved on the drying assembly. The vibrating component is disposed at the bottom of the feeding cylinder 3. The elastic support assembly is disposed between the bottom of the feeding cylinder 3 and the inner wall of the bottom of the tank 1. Preferably, a discharge groove 32 is fixedly installed on the discharge end of the spiral material plate 31. The discharge groove 32 passes through the feeding cylinder 3 and freely exits through the discharge port 11. The discharge groove 32 is arranged close to the bottom of the feeding cylinder 3. Aniline acetonitrile moves along the spiral material plate 31 and is dried by the action of vibration. After drying, it is discharged from the tank 1 through the discharge groove 32.

[0030] The vibrating component includes two vibrating motors 5 fixedly installed on the bottom of the feeding cylinder 3, with the two vibrating motors 5 located on both sides of the drying component; the two vibrating motors 5, in conjunction with the elastic support component, drive the feeding cylinder 3 and the spiral material plate 31 fixedly installed inside it to vibrate; the specific structure and working principle of the vibrating motors 5 are existing technologies.

[0031] like Figure 1-2As shown, according to another embodiment of the present invention, the spiral vibration drying device further optimizes the elastic support assembly, which includes a plurality of support units disposed between the bottom of the feeding cylinder 3 and the inner wall of the bottom of the tank 1. The plurality of support units are arranged in pairs facing each other, and the two support units arranged in each pair are respectively located on both sides of the drying assembly.

[0032] Each of the aforementioned support units includes a support cylinder 4 vertically fixedly installed on the inner wall of the bottom of the tank 1 and a connecting column 41 slidably passing through the upper inner and outer sides of the support cylinder 4 along its axial direction. The connecting column 41 is fixedly connected to the bottom of the feed cylinder 3. A spring 42 is sleeved on the outer side of the end of the connecting column 41 located outside the support cylinder 4. The spring 42 is elastically connected between the bottom of the feed cylinder 3 and the opening of the support cylinder 4.

[0033] During the operation of the two vibration motors 5, the connecting column 41 is driven to slide between the inner and outer sides of the support cylinder 4, and in conjunction with the elastic force of the spring 42, the feeding cylinder 3 and the spiral plate 31 fixedly installed inside it are vibrated.

[0034] like Figure 1 as well as Figure 3 As shown, according to another embodiment of the present invention, the spiral vibration drying device further optimizes its drying components. The drying components include a heating pipe 2 vertically fixedly installed inside the tank 1. The upper end of the heating pipe 2 is closed, and the lower end of the heating pipe 2 freely extends out of the bottom of the tank 1 and is connected to an external heat source. A plurality of air outlet holes 21 are opened along its axial direction on the side wall of the heating pipe 2. The plurality of air outlet holes 21 are evenly distributed along the circumference of the heating pipe 2, and the aperture of the air outlet holes 21 is smaller than the particle size of aniline acetonitrile, thereby preventing aniline acetonitrile from entering the air outlet holes 21. The external heat source is a device that provides hot air (such as a hot air blower). The external heat source introduces hot air into the heating pipe 2, and the hot air is blown out from the plurality of air outlet holes 21, thereby fully drying the aniline acetonitrile that is vibrating and feeding along the spiral feed plate 31.

[0035] like Figure 1 As shown, according to another embodiment of the present invention, the spiral vibration drying device preferably has a hopper 6 fixedly installed on the top of the tank 1. The top of the hopper 6 is provided with a feed hopper 61, and the bottom of the hopper 6 is provided with a discharge pipe 62. The discharge pipe 62 passes through the top of the tank 1 and is arranged near the feed end of the spiral material plate 31. When feeding, aniline acetonitrile enters the hopper 6 through the feed hopper 61 and then falls onto the spiral material plate 31 from the discharge pipe 62. In order to control the discharge speed of the discharge pipe 62, a pneumatic valve driven by an external air source can also be installed on the discharge pipe 62. The specific structure, working principle and control method of the pneumatic valve are all existing technologies and will not be described in detail here.

[0036] Preferably, a dispersing mechanism is provided between the inner and outer sides of the hopper 6. The dispersing mechanism includes a dispersing component that is horizontally rotatably installed inside the hopper 6 and a drive motor 7 fixedly installed on one side of the hopper 6. The power output shaft of the drive motor 7 freely passes through the hopper 6 and is connected to the dispersing component. The dispersing component includes a rotating shaft 71 that is horizontally rotatably installed inside the hopper 6 and a plurality of dispersing blades 72 evenly distributed along the axial direction of the rotating shaft 71. The power output shaft of the drive motor 7 freely passes through the hopper 6 and is coaxially and fixedly connected to the rotating shaft 71. The aniline acetonitrile entering the hopper 6 is dispersed by the plurality of dispersing blades 72 to prevent the aniline acetonitrile from agglomerating and sticking together before drying, which would affect the drying effect. The drive motor 7 and the aforementioned vibration motor 5 are both powered by an external power source.

[0037] The working principle of this invention is as follows: When using this invention, the drive motor 7 is first started to drive the rotating shaft 71 and several dispersing blades 72 to rotate. At the same time, two vibration motors 5 are started. During the operation of the two vibration motors 5, the connecting column 41 is driven to slide between the inner and outer sides of the support cylinder 4. With the elastic force of the spring 42, the feeding cylinder 3 and the spiral material plate 31 fixedly installed inside it are vibrated. Then, hot air is introduced into the heating pipe 2 through an external heat source, so that the hot air is blown out from several air outlets 21. Then, the aniline acetonitrile to be dried is poured from the feed hopper 61 into the silo 6. After being dispersed by several dispersing blades 72, it falls onto the spiral material plate 31 through the discharge pipe 62 and vibrates to discharge. During the discharge process, the hot air blown out from several air outlets 21 fully dries the aniline acetonitrile. The dried aniline acetonitrile is discharged from the discharge port 11 through the discharge trough 32.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
