Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a drying device for concrete raw materials. Background Art

[0002] In the process of concrete production, the drying of raw materials is a key step to ensure product quality. The main raw materials of concrete, such as sand, quartz sand, crushed stones, etc., often contain a high level of moisture before processing and use. If this moisture is not effectively removed, it will seriously affect the strength and durability of the concrete. Therefore, the drying device plays a crucial role in the pretreatment process of concrete raw materials.

[0003] At present, the flat drying device is widely used in the drying process of concrete raw materials due to its advantages such as simple structure, convenient operation, and high drying efficiency. The flat drying device usually spreads the raw materials on a large drying surface to increase the contact area between the raw materials and hot air, thereby accelerating the evaporation of moisture and achieving the purpose of rapid drying.

[0004] However, the flat drying device requires a large floor area. In today's increasingly tense land resources, such a large-footprint drying device may bring greater economic pressure to enterprises, especially in urban areas or areas with high land costs, this pressure is more obvious.

[0005] Therefore, those skilled in the art have proposed a drying device for concrete raw materials. Content of the Utility Model

[0006] In view of the above problems existing in the prior art, the main purpose of the present utility model is to provide a drying device for concrete raw materials.

[0007] The technical solution of the present utility model is as follows: A drying device for concrete raw materials, including a placing cylinder. The bottom of the inner wall of the placing cylinder is rotatably connected with a main shaft, and the top of the inner wall of the placing cylinder is fixedly connected with a fixed gear. The top of the main shaft is rotatably connected with the bottom of the fixed gear. Two annular groove plates are symmetrically and fixedly connected to the inner wall of the placing cylinder. Two connecting plates are symmetrically and fixedly connected to the outer side of the main shaft. One end of each connecting plate is fixedly connected with a sliding block, and the sliding blocks are all slidably connected inside the annular groove plates. Two rotating shafts are symmetrically and rotatably connected between the two connecting plates and on the outer side of the main shaft. Auger blades are fixedly connected to the outer sides of the rotating shafts, and rotating gears are fixedly connected to the tops of the rotating shafts. The rotating gears are all meshed with the fixed gear.

[0008] Through the above technical means, when the main shaft rotates, it can drive the connecting plate to rotate. When the connecting plate rotates, the rotating shaft will also rotate simultaneously. When the rotating shaft rotates, the rotating gear will rotate around the fixed gear and mesh at the same time, thereby driving the rotating shaft to rotate, and further causing the auger blade to rotate, so as to stir the raw materials inside the placing cylinder and drive the raw materials at the bottom upward.

[0009] As a preferred embodiment, a first driving motor is fixedly connected to the bottom of the placing cylinder. The output end of the first driving motor extends into the placing cylinder and is fixedly connected to the bottom of the main shaft. Legs are fixedly connected to the bottom of the placing cylinder at equal intervals outside the first driving motor, and a bottom plate is fixedly connected between the bottoms of the legs.

[0010] Through the above technical means, by setting the first driving motor, the main shaft can be driven to rotate.

[0011] As a preferred embodiment, two vertical plates are symmetrically and fixedly connected to the top of the bottom plate outside the placing cylinder. A bidirectional lead screw is rotatably connected between the two vertical plates. A smooth rod is fixedly connected between the two vertical plates on one side of the bidirectional lead screw. Two adjusting blocks are symmetrically connected to the outer sides of the smooth rod and the bidirectional lead screw.

[0012] Through the above technical means, by rotating the bidirectional lead screw, the adjusting block can be driven to move.

[0013] As a preferred embodiment, a drying plate is fixedly connected between the two corresponding adjusting blocks, and heating wires are arranged inside the drying plate.

[0014] Through the above technical means, the movement of the adjusting block drives the two drying plates to move towards each other, and further enables the two drying plates to approach the placing cylinder for drying operation.

[0015] As a preferred embodiment, a feed hopper is fixedly connected to the top of the placing cylinder. The feed hopper extends into the placing cylinder, and a discharge pipe is fixedly connected to the bottom of the placing cylinder.

[0016] Through the above technical means, by setting the feed hopper, the concrete raw materials can be discharged into the placing cylinder, and the discharge pipe can discharge the dried concrete raw materials.

[0017] As a preferred embodiment, a second driving motor is fixedly connected to the outside of one of the vertical plates, and the output end of the second driving motor is fixedly connected to one end of the bidirectional lead screw.

[0018] Through the above technical means, the second driving motor can provide rotational power for the bidirectional lead screw.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0020] By starting the first driving motor, the main shaft is driven to rotate by the first driving motor. When the main shaft rotates, it can drive the connecting plate to rotate. When the connecting plate rotates, the rotating shaft will also rotate at the same time. When the rotating shaft rotates, the rotating gear will rotate around the fixed gear and mesh at the same time, thereby driving the rotating shaft to rotate, and further causing the auger blade to rotate, so as to stir the raw materials inside the placing cylinder and drive the raw materials at the bottom upward. Through such a setting, it can ensure that the raw materials inside the placing cylinder are stirred to achieve the effect of uniform heating, and can greatly improve the drying efficiency.
