Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying equipment, in particular to a double-cone drying machine. Background Art
[0002] The original drying equipment of the project is a flat oven. The materials need to be placed in the drying tray for vacuum drying. During the drying process, the dried materials in the oven need to be turned over intermittently (to ensure the uniformity of drying). The process involves opening the oven, which has high potential risks in terms of safety and environmental protection (VOCS will be generated during the turning process). At the same time, turning the materials requires employee operation, resulting in low production efficiency (each time the materials are turned over, nitrogen needs to be slowly broken through the air. Breaking the air too quickly can easily cause the materials to be blown out of the drying tray; the turning process requires too much labor from the workers), making it difficult to carry out large-scale continuous production. It is now necessary to improve the drying equipment in terms of safety and environmental protection, improving drying uniformity and production efficiency.
[0003] In this solution, a double cone dryer is therefore needed to improve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a double-cone dryer, integrate the drying production line, reduce the risk in the drying process, improve the working environment of employees, improve work efficiency, and achieve stable and continuous large-scale production to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A double-cone dryer comprises a cyclone separator, wherein an air inlet of the cyclone separator is provided with a vacuum pipe, one end of the cyclone separator is provided with a liquid discharge port, the double-cone dryer is installed at one end of the vacuum pipe, a worm gear reducer is connected to the outer wall of the double-cone dryer via a transmission belt, the transmission end of the worm gear reducer is connected to an explosion-proof motor via a transmission belt, a jacket is installed on the inner wall of the double-cone dryer, an inner tank is installed on the inner wall of the jacket, a punched mesh air outlet is installed in the inner cavity of the double-cone dryer, a feed port is provided at the port of the double-cone dryer, a discharge port is installed at the port of the double-cone dryer, a hot water return pipe is installed on the outer wall of the jacket via a connecting pipe, and a hot water inlet pipe is installed on the outer wall of the jacket via a connecting pipe.
[0007] As a preferred solution of the utility model, the cyclone separator is located on one side of the jacket, the drain port is located directly below the cyclone separator, and a supporting structure is provided on the outer wall of the double-cone dryer.
[0008] As a preferred solution of the utility model, the worm gear reducer is located on one side of the jacket, the jacket is a hollow structure, and the inner cavity of the jacket is provided with hot water.
[0009] As a preferred solution of the utility model, the punched mesh air outlets are provided in multiple groups and are respectively located at the ports of the vacuum tube.
[0010] As a preferred solution of the utility model, the feed port is located directly below the discharge port.
[0011] As a preferred solution of the utility model, the hot water return pipe is located at one side of the hot water inlet pipe, and the connection between the connecting pipe and the jacket is a communicating structure.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. In the utility model, by using the explosion-proof motor in the drying equipment and using the centrifuged material to enter the inner tank through the feed port, it is only necessary to energize the cyclone separator to start it, and vacuum dry it through the cyclone separator. During the drying process, it is only necessary to energize the explosion-proof motor so that the explosion-proof motor drives the worm reducer through the transmission belt to drive, so that the double-cone dryer can start forward and reverse rotation, and the material is discharged through the discharge port after the drying is completed, which is beneficial to solve the problem that the dried material in the oven needs to be turned over intermittently during the drying process (to ensure the uniformity of drying). The process involves opening the oven, which has high potential risks in terms of safety and environmental protection (VOCS will be generated during the turning process); at the same time, turning over requires employee operation, resulting in low production efficiency (each time turning over requires nitrogen to break through the air slowly, breaking through the air too quickly can easily cause the material to be blown out of the drying plate; the labor of workers in the turning process is too large), and it is difficult to produce on a large scale continuously.
