Description

Technical Field

[0001] This utility model relates to the technical field of ceramic proppant production equipment, specifically a tray rack for drying semi-finished ceramic proppant. Background Technology

[0002] In the production of ceramsite proppant, the shaped semi-finished products (such as wet spherical green bodies) need to be dried to remove moisture in order to ensure the stability of the subsequent sintering process. During the drying process, the uniformity of heating of the semi-finished products directly affects the product quality. If local drying is insufficient, it is easy to cause cracking after sintering. If local drying is excessive, it may cause a decrease in the strength of the green body.

[0003] Currently, the commonly used drying equipment is the hot air circulating oven, which uses a circulating fan to blow heated air onto each layer of the tray rack. Since the hot air mostly flows in one direction and the bottom of the tray is a sealed structure, the semi-finished products located at the bottom of the tray are heated unevenly, resulting in low drying efficiency and high energy loss. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a tray rack for drying semi-finished ceramsite proppant, which can effectively improve the drying uniformity of semi-finished ceramsite proppant and shorten the drying cycle, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tray rack for drying semi-finished ceramsite proppant, comprising a base, a vertical tube fixed at the middle of the upper surface of the base, at least two trays evenly distributed along the height direction on the outer side of the vertical tube, through holes evenly distributed on the bottom of the trays, a guide plate disposed below the trays, the guide plate being fixed on the outer side of the vertical tube, air guide holes evenly distributed on the outer side of the vertical tube located between the guide plate and the bottom of the trays, the upper end of the vertical tube being an open end, the open end of the vertical tube corresponding to the air outlet position of one of the air supply pipes.

[0006] As a preferred embodiment of this utility model, the tray is a disc-shaped structure with grooves.

[0007] As a preferred embodiment of this utility model, the guide plate has a disc-shaped structure, and the upper surface of the guide plate is an inclined surface, with the upper surface of the guide plate inclined upward from the end of the vertical pipe.

[0008] As a preferred embodiment of this invention, the radial dimension of the guide plate is larger than the radial dimension of the tray.

[0009] As a preferred embodiment of this utility model, the air guide hole is an upward-sloping hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the tray rack for drying the semi-finished ceramsite proppant is reasonably designed and ingeniously conceived. By setting through holes at the bottom of the tray and cooperating with the air guide holes on the vertical pipe located at the bottom of the tray, the hot airflow can be evenly penetrated into the upper and lower areas of the tray, so that the semi-finished ceramsite proppant located at the bottom and top of the tray is heated evenly, improving the consistency of drying the semi-finished ceramsite proppant, shortening the drying cycle, and saving energy.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 2 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a tray rack for drying semi-finished ceramsite proppant, including a base 1, a vertical pipe 2 fixed in the middle of the upper surface of the base 1, and at least two trays 3 evenly distributed on the outer side of the vertical pipe 2 along its height direction. Each tray 3 has an air supply pipe on one side, so that hot air is blown towards the upper end of the tray 3 to dry the semi-finished ceramsite proppant placed on the tray 3.

[0016] The bottom of the tray 3 is evenly distributed with through holes 4, the diameter of which is 5-8mm and the spacing between the holes is 10-15mm, to facilitate the penetration of hot air. A guide plate 5 is set below the tray 3 and is fixed to the outer side of the vertical pipe 2. The outer side of the vertical pipe 2, located between the guide plate 5 and the bottom of the tray 3, is evenly distributed with air guide holes 6. The upper end of the vertical pipe 2 is an open end and the bottom end is a sealed end. The open end of the vertical pipe 2 corresponds to the air outlet of one of the air supply pipes. Hot air is blown into the vertical pipe 2 through the air supply pipe, so that the hot air is blown from the air guide holes 6 on the vertical pipe 2 to the bottom of the tray 3. Under the action of the guide plate 5, the hot air is guided through the through holes 4 at the bottom of the tray 3 to dry the ceramsite support semi-finished product located at the bottom of the tray 3, thereby making the ceramsite support placed in the tray 3 evenly heated.

[0017] The air guide plate 5 is located 10cm below each tray 3, ensuring that the air guide hole 6 is completely located in the area between the air guide plate 5 and the tray 3.

[0018] Specifically, tray 3 is a disc-shaped structure with grooves, which facilitates the placement of semi-finished ceramsite support agent, while the through holes 4 are uniformly annular, which facilitates the uniform diffusion of hot airflow.

[0019] In this embodiment, the guide plate 5 has a disc-shaped structure, and the upper surface of the guide plate 5 is an inclined surface. The inclined direction of the upper surface of the guide plate 5 is upward from the end of the vertical pipe 2, and the inclined angle is 10 to 20°, which facilitates the uniform guidance of hot airflow to the bottom area of ​​the tray 3.

[0020] Specifically, the radial dimension of the deflector 5 is larger than the radial dimension of the tray 3.

[0021] In this embodiment, the air guide hole 6 is an upward-sloping hole with an inclination angle of 30 to 45°, which facilitates better diffusion of the hot air in the vertical pipe 2 to the bottom of the tray 3.

[0022] In use: The circulating fan sends the heated airflow through multiple air supply pipes to the upper part of the tray 3 and the vertical pipe 2. The upper part of the ceramsite proppant semi-finished product in the tray 3 is dried by the hot airflow blown out from the upper part. The ceramsite proppant semi-finished product at the bottom of the tray 3 is dried by passing through the through hole 4 on the tray 3 under the guidance of the air guide hole 6 and the guide plate 5 on the vertical pipe 2, so as to achieve uniform drying and shorten the drying cycle.

[0023] The parts of the utility model not described in detail are prior art. Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model.
