Description

Technical Field

[0001] This utility model relates to the technical field of drying devices for the production of environmentally friendly flame retardants, and in particular to a drying device for the production of environmentally friendly flame retardants. Background Technology

[0002] For example, CN223165856U describes a flame retardant drying device. Like common flame retardant drying devices, it uses a stirring mechanism to improve drying efficiency. It also incorporates a fan to enhance high-temperature air circulation. However, like most other drying devices, it suffers from the following problems: 1. The stirring mechanism needs to be a certain distance away from the bottom wall of the drying oven, or the stirring mechanism can be in contact with the bottom wall. However, after long-term use, friction will also create a certain gap, resulting in a layer of flame retardant on the bottom wall that cannot be stirred, leading to uneven drying effect. Utility Model Content

[0003] Therefore, it is necessary to provide a drying device for the production of environmentally friendly flame retardants to address the technical problem of uneven drying effect caused by the gap between the stirring mechanism and the bottom wall of the drying chamber.

[0004] To achieve the above objectives, this utility model provides a drying device for the production of environmentally friendly flame retardants, including a frame, a heating tank, and a drying tank. The frame is equipped with a liftable stirring mechanism. The drying tank is placed inside the heating tank. A limit ring is threaded to the bottom of the drying tank. A concave bottom is engaged between the limit ring and the drying tank. A connecting block is installed at the bottom of the concave bottom. A linear actuator is installed on the frame. A connecting ring is installed at the output end of the linear actuator. The connecting block is inserted into the connecting ring. The same connecting rod is inserted into the connecting block and the connecting ring.

[0005] Preferably, the limiting ring is equipped with a plurality of limiting blocks, and the concave bottom is provided with limiting grooves corresponding to the limiting blocks one by one, and the limiting blocks are engaged in the limiting grooves.

[0006] Preferably, a flexible guide ring is installed at the bottom of the drying barrel.

[0007] Preferably, a heating block is installed on the inner wall of the heating barrel.

[0008] Preferably, the stirring mechanism includes a bucket lid, a stirring shaft rotatably mounted on the bucket lid, a rotary drive device mounted on the bucket lid, and the output end of the rotary drive device being connected to the stirring shaft for transmission.

[0009] Preferably, the bottom of the heating barrel is provided with a through hole for the connecting block to extend out.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. By setting the concave bottom, the linear actuator can push the concave bottom to vibrate during drying, so that the flame retardant can move from the edge to the center and be stirred. After a certain period of time, the linear actuator can push the concave bottom to make the central depression bulge, thereby guiding the flame retardant in the center to the edge, ultimately improving the drying effect. 2. The design of the connecting block, connecting ring, and connecting rod enables the concave bottom to vibrate and allows the drying drum to be easily removed and replaced.

Detailed Implementation

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 3 This application provides a drying device for the production of environmentally friendly flame retardants, including a frame 1, a heating tank 2, and a drying tank 3. The drying tank 3 is actually annular, with a concave bottom 5. The drying tank 3 has an opening for workers to hook and lift it. The frame 1 is equipped with a liftable stirring mechanism. The drying tank 3 is placed inside the heating tank 2. A limit ring 4 is threaded to the bottom of the drying tank 3. The concave bottom 5 is engaged between the limit ring 4 and the drying tank 3. The concave bottom 5 is a disc structure with an inwardly concave center. The concave bottom 5 can be made of low-cost elastic metal such as spring steel. A connecting block 6 is fixedly installed at the bottom of the concave bottom 5. A linear actuator 7 is fixedly installed on the frame 1. The linear actuator 7 can be an electric cylinder that is connected to an external signal processor. A connecting ring 8 is fixedly installed at the output end of the linear actuator 7. The connecting block 6 is inserted into the connecting ring 8. The connecting block 6 and the connecting ring 8 are connected to the same connecting rod 9.

[0014] In this embodiment, the drying barrel 3 and the concave bottom 5 together form a drying box for holding materials. After the drying barrel 3 is placed into the heating barrel 2, flame retardant powder can be added into it. During placement, the connecting block 6 can be inserted into the connecting ring 8. Then, the stirring mechanism can be driven to descend to perform the sealing and stirring drying work. During stirring, the linear actuator 7 can push the concave bottom 5 to vibrate through the insertion of the connecting ring 8 and the connecting block 6. Specifically, the vibration can be caused by a certain gap between the connecting rod 9 and the insertion hole, so that the connecting ring 8 drives the connecting rod 9 to rise and collide with the insertion hole, producing a vibration effect. The vibration effect allows the flame retardant to move from the edge to the center and then push for stirring. After mixing and vibrating for a certain period of time, the linear actuator 7 can push the concave bottom 5, making its central depression convex. This can guide the flame retardant in the center to the edge, ultimately improving the drying effect. When convex, the linear actuator 7 can also perform small displacement extension and retraction vibration. Afterward, the linear actuator 7 pulls the concave bottom 5 back to its original position. The above operation can be repeated after a period of time. Damping springs and elastic pads can be added between the linear actuator 7 and the connecting ring 8 to reduce the damage of vibration to the linear actuator 7. The concave bottom 5 is limited by the drying barrel 3 and the limiting ring 4 after assembly. There should be a suitable gap between the concave bottom 5 and the bottom of the stirring mechanism to allow the concave bottom 5 to convex.

[0015] In some embodiments, to facilitate the deformation of the concave bottom 5, a plurality of limiting blocks 10 are fixedly installed on the limiting ring 4, and limiting grooves 11 corresponding to the limiting blocks 10 are formed on the concave bottom 5, with the limiting blocks 10 engaging in the limiting grooves 11. Thus, when the concave bottom 5 vibrates or bulges and deforms, it can be more stable through the sliding engagement relationship between the limiting blocks 10 and the limiting grooves 11; and to facilitate the deformation of the concave bottom 5, both the limiting ring 4 and the drying barrel 3 can be provided with chamfers to match them.

[0016] In some embodiments, to reduce the loss of flame retardant from the connection between the drying barrel 3 and the concave bottom 5, a flexible guide ring 12 is fixedly installed at the bottom of the drying barrel 3. The flexible guide ring 12 can be made of high-temperature resistant flexible rubber material, so that when it bulges on the concave bottom 5, it can be squeezed against it, so that the flame retardant will not leak out from the gaps.

[0017] In some embodiments, to facilitate heating of the drying barrel 3, a plurality of spaced heating blocks 13 are fixedly installed on the inner wall of the heating barrel 2.

[0018] In some embodiments, to facilitate the stirring of the flame retardant in the drying barrel 3, a stirring mechanism is provided, including a barrel cover 14, a stirring shaft 15 rotatably mounted on the barrel cover 14, and a rotary drive device 16 fixedly mounted on the barrel cover 14. The rotary drive device 16 can be a servo motor connected to an external signal processor, and its output end is connected to the stirring shaft 15 for transmission. The barrel cover 14 can be lowered and closed to the heating barrel 2 by manual or electric cylinder drive, after which the rotary drive device 16 drives the stirring shaft 15 to rotate and stir. The stirring shaft 15 below the barrel cover 14 can also drive a fan to operate through existing gear transmission, and a ventilation screen can be added to achieve rapid air circulation.

[0019] In some embodiments, to facilitate the insertion of the connecting block 6 into the connecting ring 8, a through hole is provided at the bottom of the heating barrel 2 for the connecting block 6 to extend out. The through hole can be clearance-fitted with the connecting block 6, thereby reducing heat dissipation.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
