Technical Field

[0001] The utility model relates to the technical field of powder drying equipment, in particular to a coating concrete preservative drying device. Background Art

[0002] Concrete is one of the most widely used building materials in modern construction projects. In order to improve the comprehensive performance of concrete, it is usually necessary to add various admixtures, such as preservatives, during the preparation process. Preservatives can significantly improve the corrosion resistance and service life of concrete.

[0003] At present, the preparation process of coated concrete preservatives is mostly: first, the anticorrosive material is coated and pretreated to form a low-flow or paste material, and then dried and formed. Common drying methods include high-temperature drying, spray drying, centrifugal vacuum drying, fluidized bed drying, etc. However, these drying methods all have certain defects: high-temperature drying easily leads to uneven heating of the coated preservative; and drying methods such as spraying, centrifugal vacuum, and fluidized bed are not suitable for drying low-flow paste materials, and the efficiency is low.

[0004] In order to solve the above problems and improve the uniformity and efficiency of drying the coated concrete preservative, the utility model designs a vibration drying device with a unique structure. The device adopts a rotatable horizontal cylindrical drying tank, and is equipped with a vibration device and a uniform heating device, so that the material can maintain a fully flowing and dispersed state during the drying process, thereby greatly improving the heating uniformity and drying rate of the material.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0029] Figure 1 It is a schematic diagram of a vibration drying device for coating concrete preservative according to an embodiment of the present invention. DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides a vibration drying device for coating concrete preservative, which is composed of a base and a drying tank 2 arranged on the base. Figure 1 As shown, the drying tank 2 is a horizontal cylindrical structure, with a feed port 1 at the upper end for loading preservative materials, and a discharge port 7 at the lower end for unloading the dried product.

[0032] A plurality of elastic components, such as springs, vibration-damping pads, etc., are provided between the drying tank 2 and the base, so that the drying tank 2 can generate vibration displacement relative to the base. A transmission device for providing rotational power is provided in the middle of one side of the drying tank 2. The transmission device includes a transmission motor 4 and a transmission belt 5 connected to the drying tank 2. The operation of the transmission motor 4 drives the transmission belt 5 to rotate, thereby causing the drying tank 2 to rotate around its long axis, promoting the internal material to roll and flip along the tank wall.

[0033] In addition, a vibration device is provided at an eccentric position at the bottom of the drying tank 2, including a vibration motor 6. The eccentric operation of the vibration motor 6 generates a centrifugal vibration force, which is transmitted to the drying tank 2 through the eccentric connection with the bottom of the drying tank 2, so that the drying tank 2 generates an overall vibration. Under the combined effect of the rotation and vibration of the drying tank 2, the internal material realizes a three-dimensional flow, and the material particles are separated and redispersed from each other, thereby greatly increasing the contact area between the material and the heat source and the heat transfer efficiency.

[0034] A heating device 3 is wound around the outside of the drying tank 2, which can be heated by electricity or steam to provide a uniform heat source for the inner wall of the drying tank 2. The heating device 3 heats the inner wall uniformly, so that the material can be heated uniformly in the drying tank 2.

[0035] The working process of the device is as follows: first, the coated preservative material is loaded into the drying tank 2 through the feed port 1, and then the transmission motor 4, the vibration motor 6 and the heating device 3 are started. The transmission motor 4 drives the drying tank 2 to rotate, the vibration motor 6 makes the drying tank 2 vibrate, and the heating device 3 heats the inner wall. Under the combined effect of the rotation, vibration and uniform heating of the drying tank 2, the internal material is thoroughly fluidized, dispersed, and heated evenly, thereby greatly improving the drying rate and drying quality of the material. After the drying is completed, the dried finished material can be unloaded from the discharge port.

[0036] By adopting the above structure and working mode, the vibration drying device effectively solves the problem of uneven heating of materials and low efficiency caused by viscosity during the drying process of the coated concrete preservative, and can effectively improve the quality and efficiency of drying the coated preservative.

[0037] In other embodiments, the utility model may also include the following technical solutions:

[0038] In order to further improve the fluidity and dispersibility of the material in the drying tank, a plurality of protruding stirring pins or stirring rods are evenly arranged on the inner wall of the drying tank 2. These stirring pins (rods) can be a fixed structure nailed into the tank wall, or a movable and rotatable structure. When the drying tank 2 rotates, the stirring pins (rods) on the inner wall extend into the material layer under the action of centrifugal force, stirring and breaking up the material layer, so that the material is completely fluidized. The setting of the stirring pins (rods) greatly enhances the fluidity and dispersibility of the material.

[0039] In addition, in order to further improve the convective heat transfer effect of the material inside the drying tank, a plurality of heat transfer disks can be arranged axially at intervals inside the drying tank 2. These heat transfer disks can be metal disk-shaped structures, and the diameter of the disks is smaller than the inner diameter of the drying tank, so that the material can flow between the disks. The heat transfer disks can be thermally connected to the inner wall of the drying tank 2, so as to quickly and evenly transfer the heat of the inner wall to the material layer inside the drying tank. The arrangement of the heat transfer disks is conducive to improving the convective heat transfer efficiency of the material during the drying process.

[0040] Furthermore, in order to further control and optimize the drying process, detection devices such as temperature sensors and level meters can be installed on the drying tank 2 or the base, and electrically connected to the control system. The control system can automatically adjust the heating power of the heating device 3, the vibration intensity of the vibration motor 6 and other process parameters according to the real-time detection values ​​of the temperature, position and other parameters of the material layer, so as to realize the automatic control of the entire drying process and improve the drying quality and stability.

[0041] By adopting the above-mentioned multiple innovative technical solutions, such as the inner wall stirring device, internal heat transfer disk, automatic control system, etc., the vibration drying device is further optimized and improved on the original basis, which can enable the coated preservative material to achieve more thorough flow, dispersion and convection heat exchange in the drying tank, and the entire drying process is more efficient, uniform and controllable, greatly improving the drying quality and efficiency.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
