Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate drying equipment, in particular to a calcium carbonate three-drum drying machine. Background Art

[0002] The calcium carbonate three-drum dryer is a common calcium carbonate drying equipment. Its principle is to use the heat transfer between hot air and calcium carbonate particles to evaporate the water in calcium carbonate, so as to achieve the purpose of drying. The calcium carbonate three-drum dryer is mainly composed of a base and a dryer body. The dryer body is composed of three coaxial horizontally placed inner, middle and outer cylinders. The calcium carbonate material and hot air enter the inner, middle and outer cylinders in turn, forming a Z-shaped moving path in the arch dryer body, and are discharged after reciprocating and baffled for sufficient heat exchange. The calcium carbonate three-drum dryer is in a rotating state when in use. The driving wheel and the supporting wheel are respectively arranged on both sides of the base. The dryer body is erected between the driving wheel and the supporting wheel. When the driving wheel rotates, the dryer body can be driven to rotate. In the existing three-drum dryer, the distance between the driving wheel and the supporting wheel is relatively fixed. It has a good driving and supporting effect on the dryer body placed between the two and of a certain cylinder diameter. When the cylinder diameter of the dryer body changes, although it can be barely erected between the driving wheel and the supporting wheel, its driving effect will be reduced, and its use is relatively limited.

[0003] Therefore, how to provide a calcium carbonate three-drum dryer that can have good driving and supporting effects for dryer bodies of various drum diameters is a topic that needs to be studied urgently by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0020] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a calcium carbonate three-drum dryer, comprising a base 1, a driving assembly 2 and a supporting assembly 3 respectively mounted on opposite sides of the base 1, and a dryer body 4 mounted between the driving assembly 2 and the supporting assembly 3. The base 1 is fixedly mounted on a supporting plane (e.g., a factory floor), the driving assembly 2 is used to provide power to drive the dryer body 4 to perform a rotary motion, and the supporting assembly 3 is used to support the dryer body 4. The structure of the dryer body 4 and the drying principle belong to the prior art and will not be described in detail here.

[0022] The base 1 is a hollow quadrilateral frame structure, and the cross section of the base 1 is an I-shaped structure. The sides of the base 1 are fixedly connected with reinforcing ribs 13 to improve the structural strength of the base 1.

[0023] See also Figure 3The driving assembly 2 includes a driving wheel 21, and the supporting assembly 3 includes a supporting wheel 31. The driving wheel 21 and the supporting wheel 31 are rotatable relative to the base 1. A belt 41 is provided on the outer wall of the dryer body 4 along the circumference of the dryer body 4. The belt 41 is a circular ring structure coaxial with the dryer body 4, and the belt 41 is mounted on the driving wheel 21 and the supporting wheel 31 at the same time. When working, the driving wheel 21 rotates, and the friction between the driving wheel 21 and the belt 41 drives the dryer body 4 to make a rotary motion. In order to achieve stable support for the dryer body 4, there are at least two driving wheels 21 and two supporting wheels 31, wherein one driving wheel 21 corresponds to one supporting wheel 31.

[0024] In the present embodiment, there are two driving wheels 21 and two supporting wheels 31, and correspondingly, there are also two wheel belts 41. The two opposite sides of the two driving wheels 21 and the two opposite sides of the two supporting wheels 31 are radially protruded with limiting edges 210, and the limiting edges 210 are in contact with the end surfaces of the two wheel belts 41 that are close to each other. In this way, the axial displacement of the dryer body 4 is limited, thereby preventing the dryer body 4 from being separated from the driving wheel 21 and the supporting wheel 31.

[0025] See also Figure 1 The driving assembly 2 further includes a reducer 22 and a driving motor 23. The reducer 22 is fixedly mounted on the base 1. The output shaft of the driving motor 23 is fixedly connected to the power input end of the reducer 22. The power output end of the reducer 22 is fixedly connected to the central axis of the driving wheel 21. As a preferred embodiment, a support frame 11 is fixedly mounted on the upper end surface of the base 1. The central axis of the driving wheel 21 is rotatably connected to the support frame 11. By providing the support frame 11, the load capacity of the driving wheel 21 is improved, and the normal operation of the driving wheel 21 is ensured.

[0026] See also Figure 2 The support assembly 3 also includes two sliding seats 32 arranged opposite to each other and a fixed shaft 33 fixedly connected between the two sliding seats 32. The sliding seat 32 is slidably arranged on the base 1 along the direction approaching or away from the driving assembly 2. The two support wheels 31 are rotatably mounted on the fixed shaft 33. A fixed plate 12 is fixedly connected to the base 1. A supporting member 14 is threadedly penetrated on the fixing plate 12. The end of the supporting member 14 is abutted against the side of the sliding seat 32 away from the driving assembly 2.

[0027] When in use, the user adjusts the position of the support wheel 31 by sliding the sliding seat 32, thereby changing the distance between the support wheel 31 and the driving wheel 21, so as to adapt to the installation requirements of the dryer body 4 with different cylinder diameters. When the position of the support wheel 31 is adjusted to the right position, the abutment 14 is rotated so that the end of the abutment 14 abuts against the sliding seat 32, thereby locking the position of the support wheel 31.

[0028] In this embodiment, the abutment member 14 is a bolt. The bolt has a self-locking property, which can prevent the abutment member 14 from easily moving along its own axial direction, thereby improving its limiting stability on the sliding seat 32.

[0029] As a preferred embodiment, a fixed block 15 is fixedly connected to the upper surface of the base 1, and a "convex"-shaped slide groove 151 is opened on the fixed block 15. The lower end of the sliding seat 32 is slidably connected to the slide groove 151, and the fixed plate 12 is located at the end of the fixed block 15 away from the driving assembly 2.

[0030] As a preferred embodiment, a fixing seat 16 is fixedly connected to the upper surface of the base 1, and a guide groove 161 is provided on the upper surface of the fixing seat 16. The guide groove 161 is parallel to the slide groove 151, and a slider 17 is slidably installed in the guide groove 161. The fixed shaft 33 is fixedly inserted in the slider 17, and a screw rod 18 is rotatably installed on the fixing seat 16. The screw rod 18 extends into the guide groove 161 and is threadedly connected with the slider 17. A screw motor 19 for driving the screw rod 18 to rotate is fixedly installed at one end of the fixing seat 16. When in use, the screw motor 19 is started to drive the screw rod 18 to rotate. When the screw rod 18 rotates, it drives the slider 17 to slide along the guide groove 161, thereby driving the fixing shaft 33 and the support wheel 31 on the fixing shaft 33 to move synchronously, thereby realizing the adjustment of the position of the support wheel 31. In the above process, the support wheel 31 is driven to move by a screw transmission, thereby achieving micro adjustment and ensuring the movement accuracy of the support wheel 31. At the same time, the slider 17 has a certain self-locking function under the action of the screw 18, which effectively avoids the problem of the support wheel 31 moving at will.

[0031] The calcium carbonate three-drum dryer of the present invention adjusts the position of the support wheel 31 by sliding the sliding seat 32, thereby changing the distance between the support wheel 31 and the driving wheel 21, so as to adapt to the installation requirements of the dryer body 4 with different drum diameters. When the position of the support wheel 31 is adjusted to the right position, the abutment member 14 is rotated so that the end of the abutment member 14 abuts against the sliding seat 32, thereby locking the position of the support wheel 31. The utility model is reliable in use, improves the versatility of the base 1, and is easy to promote and use.

[0032] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
