Description

A horizontal dryer

Technical Field

The utility model relates to the technical field of dryers, in particular to a horizontal dryer.

Background Art

Horizontal dryer is also called fluidized bed. After continuous application and improvement, it has played an increasingly important role in the fields of chemical industry, pharmaceutical industry, food and grain processing. Existing horizontal dryers usually input dry hot air into the drying box when in use, and stir the materials in the dryer so that the hot air can fully contact the materials, so that the materials can be dried. However, in the prior art, the materials are usually accumulated at the bottom of the drying box after being placed in the drying box. Since hot air is lighter than cold air, it will gather at the top of the drying box. In this way, the temperature at the bottom of the drying box will rise slowly, thereby prolonging the drying time of the materials.

For example, a horizontal dryer disclosed in a Chinese utility model patent with a publication number of CN211854733U and an authorization announcement date of November 3, 2020, includes a frame, a drying cylinder, a feed port, a feed door, a discharge port, and a discharge door. A mounting plate is provided on one side of the drying cylinder, and an opening is provided on the other side of the drying cylinder. A cylinder cover movably connected to the drying cylinder is provided at the opening, a central shaft is rotatably provided on the mounting plate, and a driving mechanism for driving the central shaft to rotate is provided on the mounting plate. A heating chamber is provided between the mounting plate and the bottom of the drying cylinder, a heating assembly is provided in the heating chamber, and a heat-conducting hood is provided in the heating chamber. The central shaft is a hollow structure, and the heat-conducting hood is connected to the cavity of the central shaft. A plurality of stirring blades are fixedly provided on the central shaft, a plurality of air outlets are provided on the central shaft, a plurality of mesh covers are fixedly provided on the central shaft, the mesh covers are provided at the openings of the air outlets, and an exhaust hole is provided on the cylinder cover.

However, in actual use, the above-mentioned dryer heats the material by introducing hot air into the cavity of the central axis, and prevents the granular material from clogging the vent by arranging a mesh cover outside the vent. However, when the material is put into the drying cylinder from the feed port, it will accumulate at the bottom of the drying cylinder, so that the hot air coming out of the central axis will be above the material. Since hot air is lighter than cold air, it will move to the top of the drying cylinder, so that the temperature at the bottom of the drying cylinder will rise slowly, thereby extending the drying time.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

Please refer to Figures 1-3. The utility model provides a technical solution: a horizontal dryer includes a drying box 1, a feed port 2 is provided at one end of the top of the drying box 1, a vibration motor 3 is provided at the bottom of the inner wall of the drying box 1, a mesh plate 4 is provided at the output end of the vibration motor 3, the mesh plate 4 is located at one end of the feed port 2 and is higher than the other end, the drying box 1 is provided with two transmission belts 5 above the mesh plate 4, the two rotating belts are fixedly connected to two scrapers 6, the two ends of the transmission belt 5 are respectively provided with rotating shafts 7, the rotating shaft 7 is rotatably connected to the drying box 1, a driving motor 8 is provided at one end of the outer wall of the drying box 1, the output end of the driving motor 8 is fixedly connected to the rotating shaft 7, a hot air blower 9 is provided at one end of the bottom of the drying box 1, and the output end of the hot air blower 9 is connected to the drying box 1,

In this embodiment, first, the materials are put into the drying box 1 from the feed port 2. After entering the drying box 1, the materials will fall onto the mesh plate 4. Then, the hot air blower 9 is turned on, and the hot air generated by the hot air blower 9 will enter the drying box 1. Since hot air is lighter than cold air, the hot air will move toward the top of the drying box 1 after entering the drying box 1. During the movement of the hot air, the hot air will contact the materials on the mesh plate 4, thereby preliminarily drying the materials. Then, the vibration motor 3 is turned on, and the mesh plate 4 will vibrate under the drive of the vibration motor 3, so that the materials on the mesh plate 4 will jump up. In this way, the contact area between the material and the hot air is increased. Since the mesh plate 4 is set to an inclined state, the material will gradually accumulate after the vibration motor 3 is turned on. At this time, the drive motor 8 can be turned on. Under the action of the drive motor 8, the rotating shaft 7 will rotate, thereby driving the transmission belt 5 to rotate, and then driving the scraper 6 to move. When the scraper 6 moves, the accumulated materials can be scraped apart, allowing the materials to be evenly laid on the mesh plate 4. In this way, under the joint action of the hot air blower 9, the vibration motor 3 and the drive motor 8, the material can be quickly and thoroughly dried.

The drying box 1 is provided with a discharge port 10 at a lower end of the drying box 1 . In the present embodiment, the design of the discharge port 10 allows the dried material to be discharged smoothly.

A valve 11 is installed on the outer wall of the drying box 1 at the discharge port 10. In this embodiment, since it takes a certain amount of time to dry the material, the valve 11 is designed to prevent the material from being discharged from the discharge port 10 before it is dried.

The drying box 1 is connected to the output end of the hot air blower 9 through a connecting pipe 12 , and the output port of the connecting pipe 12 is located below the mesh plate 4 . In this embodiment, the design of the connecting pipe 12 allows the drying box 1 to be smoothly connected to the output end of the hot air blower 9 .

The transmission belt 5 is parallel to the mesh plate 4 . In this embodiment, in order to allow the scraper 6 to scrape the material evenly on the mesh plate 4 better, the transmission belt 5 and the mesh plate 4 are set to be parallel.

A plurality of grooves 13 are formed on one end of the scraper 6 away from the transmission belt 5. In the present embodiment, the grooves 13 formed on the scraper 6 enable the scraper 6 to scrape the material more evenly.

Working principle: When in use, first, the materials are put into the drying box 1 from the feed port 2. After entering the drying box 1, these materials will fall onto the mesh plate 4. Then, the hot air blower 9 is turned on, and the hot air generated by the hot air blower 9 will enter the drying box 1 through the connecting pipe 12. Since the air outlet of the connecting pipe 12 is located below the mesh plate 4, and since hot air is lighter than cold air, the hot air will move toward the top of the drying box 1 after entering the drying box 1. In the process of the hot air moving, it will contact the materials on the mesh plate 4, thereby preliminarily drying the materials. Then, the vibration motor 3 is turned on, and the mesh plate 4 will vibrate under the drive of the vibration motor 3, thereby making the materials on the mesh plate 4 jump, thereby increasing the contact surface between the materials and the hot air. The mesh plate 4 is set to an inclined state, so after the vibration motor 3 is turned on, the material will gradually gather towards the discharge port 10. At this time, the drive motor 8 can be turned on, and the shaft 7 will rotate under the action of the drive motor 8, thereby driving the transmission belt 5 to rotate, and then driving the scraper 6 to move. When the scraper 6 moves, the accumulated materials can be scraped apart, so that the materials can be evenly laid on the mesh plate 4. The grooves 13 provided on the scraper 6 allow it to scrape the materials more evenly when scraping the materials. In this way, under the joint action of the hot air blower 9, the vibration motor 3 and the drive motor 8, the materials can be quickly and thoroughly dried. After the materials are dried, the valve 11 of the discharge port 10 can be opened to discharge the materials from the discharge port 10.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
