AI Technical Summary
Existing manufactured sand drying equipment results in uneven drying effects. Some manufactured sand has a short residence time and fails to fully absorb heat. Hot air cannot penetrate the accumulation area, leading to incomplete drying.
The drying device uses a heating roller and an auger, combined with a fan and nozzle system. The auger tumbles and lifts the material, and the heating mesh and nozzles heat the surface of the material multiple times. The vibration motor disperses the material and improves the uniformity of drying.
This technology enables efficient and uniform drying of manufactured sand, improving drying efficiency and effectiveness, and ensuring the quality of manufactured sand.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of manufactured sand preparation technology, specifically a drying device for manufactured sand preparation. Background Technology
[0002] In today's booming construction industry, manufactured sand, as an important substitute for natural sand, is being used more and more widely, and market demand continues to rise. In the production process of manufactured sand, the drying stage is a crucial step in ensuring product quality, directly affecting the moisture content and subsequent performance of the sand. However, existing drying equipment for manufactured sand production has many shortcomings in terms of drying efficiency, making it difficult to meet the industry's growing needs.
[0003] Traditional drying devices, such as drum dryers, have relatively simple structures. The manufactured sand mainly relies on gravity and the rotation of the drum to tumble inside, with limited contact with hot air. In actual production, some manufactured sand has a short residence time inside the drum and fails to fully absorb the heat from the hot air, resulting in incomplete drying. In other areas, the manufactured sand accumulates too thickly, making it difficult for hot air to penetrate, which also leads to uneven drying. Therefore, we propose a drying device for the preparation of manufactured sand. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a drying device for the preparation of manufactured sand, which has the advantage of uniform drying. This solves the problems of traditional drying devices, such as drum dryers, which have relatively simple structures. The manufactured sand in the drum mainly relies on gravity and the rotation of the drum to tumble, and the contact with hot air is limited. In actual production, some manufactured sand has a short residence time in the drum and fails to fully absorb the heat of the hot air, resulting in incomplete drying. On the other hand, in some areas, the manufactured sand is piled up too thickly, making it difficult for hot air to penetrate, which also leads to uneven drying.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for the preparation of manufactured sand, comprising a shell, a first motor fixedly connected to the bottom left side of the shell, a drive gear fixedly connected to the output end of the first motor, a driven gear meshing with one side of the drive gear, a first auger fixedly connected to one side of the driven gear, a heating roller movably connected to the central shaft on the left side of the shell, a hollow tube connected to the bottom right side of the shell via a guide pipe, a second motor fixedly connected to the top of the hollow tube, a second auger fixedly connected to the output end of the second motor, the top left side of the hollow tube connected to the shell via a connecting pipe, a hollow block fixedly connected to the top of the back side of the shell, a fan connected to the right side of the hollow block, a heating mesh fixedly connected to the inner wall of the hollow block, an exhaust pipe connected to the left side of the hollow block, a first nozzle connected to one side of the exhaust pipe, and a second nozzle connected to the other side of the exhaust pipe.

[0008] Preferably, the bottom of the hollow tube is connected to a discharge pipe, and the bottom of the discharge pipe is threadedly connected to a cover plate.
[0009] Preferably, both sides of the inner cavity of the housing are movably connected to the heating roller via a first bearing, and the four corners of the bottom of the housing are fixedly connected with support legs.
[0010] Preferably, the top left side of the housing is connected to an injection pipe, and the bottom left side of the housing cavity is movably connected to the first auger via a second bearing.
[0011] Preferably, the front and back of the frame are fixedly connected to sliding sleeves, and the inner cavity of the sliding sleeve is slidably connected to a sliding rod, and both sides of the sliding rod are fixedly connected to the shell.
[0012] Compared with the prior art, this utility model provides a drying device for the preparation of manufactured sand, which has the following beneficial effects:
[0013] 1. This utility model injects material into the inner cavity of the shell, then starts the first motor, which drives the drive gear to rotate, which in turn drives the driven gear to rotate, thereby driving the first auger to rotate, which in turn drives the heating roller to rotate. While the material is tumbling, it is being dried. The rotation of the first auger causes the material to be discharged into the inner cavity of the hollow tube through the guide pipe. At the same time, the second motor, heating grid and fan are started. The second motor drives the second auger to rotate, thereby driving the material to rise. The material is discharged into the inner cavity of the shell through the connecting pipe. During the falling process of the material, heated gas is sprayed onto the surface of the material through the exhaust pipe, the first nozzle and the second nozzle, thereby drying the material again, making the drying process highly efficient.
[0014] 2. This utility model starts a vibration motor, which drives the frame to swing back and forth. The falling material will enter the inner cavity of the frame. The shaking of the frame can disperse the material, thereby improving the drying efficiency. Attached Figure Description

The swinging of the frame 15 can disperse the material, thereby improving the drying efficiency.
[0028] Working principle: The material is injected into the inner cavity of the shell 1, and then the first motor 2 is started. The first motor 2 drives the drive gear 3 to rotate, which in turn drives the driven gear 4 to rotate, thereby driving the first auger 5 to rotate, which in turn drives the heating roller 6 to rotate. While the material is tumbling, it is being dried. The rotation of the first auger 5 causes the material to be discharged into the inner cavity of the hollow tube 10 through the guide pipe 9. At the same time, the second motor 11, the heating grid 18 and the fan 17 are started. The second motor 11 drives the second auger to rotate, thereby driving the material to rise. The material is discharged into the inner cavity of the shell 1 through the connecting pipe 13. During the falling process of the material, heated gas is sprayed onto the surface of the material through the exhaust pipe 19, the first nozzle 20 and the second nozzle 12, thereby drying the material again, making the drying process highly efficient.
[0029] Start the vibration motor 14, which drives the frame 15 to swing back and forth. The falling material will enter the inner cavity of the frame 15. The swinging of the frame 15 can disperse the material, thereby improving the drying efficiency.
