Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. The present invention is further described below in conjunction with the embodiments.

[0044] See also Figures 1-4 In one embodiment of the present application, a drying device for preparing magnesium hydroxide flame retardant includes a drying box 1, a controller 3, and a plurality of universal wheels 4. The plurality of universal wheels 4 are symmetrically arranged on the drying box 1. The controller 3 is arranged on the drying box 1.

[0047] A heating system is provided on the drying box 1, and when the heating system is in operation, a hot air flow is generated and input into the drying seat 6; and

[0048] The driving module is arranged in the drying box 1 and connected to the gauze 16, and is used to adjust the position of the gauze 16 in the drying box 1 and drive the heating system to work;

[0049] The heating system comprises:

[0050] The air extraction box 23 is provided on the drying box 1. The air extraction box 23 is provided with an input hole and an output hole. Both the input hole and the output hole are provided with a one-way valve 28.

[0051] The heating box 22 is provided on the exhaust box 23 and is connected to the output hole. The heating box 22 is connected to the drying seat 6;

[0052] A piston 29 is movably disposed in the air extraction box 23 and the two are connected by an elastic member; and

[0053] The adjustment module is provided on the drying box 1 and connected to the input hole, and is used for adjusting the position of the drying seat 6 on the first guide column 5 .

[0054] In this embodiment, the adjustment module includes:

[0055] The air inlet box 25 is provided on the drying box 1 and is connected to the input hole;

[0056] Rotating blades 26 are movably disposed in the air inlet box 25; and

[0057] The second winding drum 27 is movably arranged in the air inlet box 25 and is coaxially connected to the rotor blade 26. The second winding drum 27 is connected to the drying seat 6 through a belt.

[0058] It should be noted that the elastic member can be a spring 24, a spring or an elastic steel plate structure. In this embodiment, the elastic member is preferably a spring 24, and the spring 24 is connected between the piston 29 and the vacuum box 23. As for the specific model parameters of the spring 24, no specific limitation is made here.

[0059] In actual application, the magnesium hydroxide flame retardant is poured into the drying box 1 and placed on the gauze 16. The controller 3 controls the driving module to control the gauze 16 and the slider 15 to move back and forth in the vertical direction, so that the magnesium hydroxide flame retardant on the screen is in a shaking state. When the driving module is working, the piston 29 can be controlled to move back and forth along the vacuum box 23, thereby drawing the outside air into the vacuum box 23 and inputting it into the heating box 22 for heating treatment. Finally, the hot air flow can be blown from the drying seat 6 to the magnesium hydroxide flame retardant on the gauze 16 to achieve the drying treatment of the magnesium hydroxide flame retardant. In this process, the external air flow input into the vacuum box 23 can drive the rotating blade 26 to rotate, thereby driving the No. 2 winding disk 27 to rotate synchronously to rewind the belt, and under the action of the spring 2, the drying seat 6 is driven to reciprocate along the No. 1 guide column 5, thereby achieving the drying treatment of the magnesium hydroxide flame retardant at different positions, further improving the drying effect of the magnesium hydroxide flame retardant.

[0060] See also Figure 1 As another preferred embodiment of the present application, the driving module includes:

[0061] A top rod 7 is provided on the gauze 16;

[0063] A telescopic element, which is provided on the drying box 1 and has an output end connected to the sliding seat 13; and

[0064] The first winding drum 9 is movably arranged in the drying box 1 and slidingly cooperates with the top rod 7. The first winding drum 9 is connected to the piston 29 through a belt.

[0065] In a specific case of this embodiment, a fixed pulley 11 is provided on the drying box 1 , and the belt between the first winding reel 9 and the piston 29 is in sliding cooperation with the fixed pulley 11 .

[0066] In another specific case of this embodiment, a damping strip No. 1 8 is provided on the push rod 7, and a damping strip No. 2 10 is provided on the reel No. 1 9, and the damping strip No. 1 8 and the damping strip No. 2 10 are slidably fitted with each other.

[0067] It should be noted that the telescopic element can be a linear motor, an electric cylinder or a hydraulic cylinder. In this embodiment, the telescopic element is preferably an electric telescopic rod 12. As for the specific model of the electric telescopic rod 12, the best choice can be made according to actual conditions and is not specifically limited here.

[0068] In actual application, the controller 3 controls the electric telescopic rod 12 to continuously extend and retract, driving the sliding seat 13 to reciprocate in the horizontal direction, so that under the action of the push rod 14, the top rod 7 and the gauze 16 can be driven to reciprocate, so that under the sliding cooperation between the No. 1 damping bar 8 and the No. 2 damping bar 10, the No. 1 winding disk 9 is driven to rotate to rewind the belt, thereby driving the piston 29 to reciprocate along the vacuum box 23, and inputting the hot air flow into the drying seat 6. In this process, not only can the shaking of the magnesium hydroxide flame retardant on the gauze 16 be controlled to improve the drying effect, but also the linkage structure can be used to drive the heating system to work synchronously, thereby reducing the power consumption of the entire device.

[0069] See also Figure 1 、 Figure 2 as well as Figure 4 As another preferred embodiment of the present application, the drying equipment further includes a turning module, which is arranged in the drying box 1. When the gauze 16 moves, the magnesium hydroxide flame retardant on the gauze 16 is turned over by the turning module.

[0070] In this exemplary embodiment, the turning module includes:

[0071] A second guide post 17 is provided between a set of sliders 15;

[0072] The moving blocks 18 are arranged in a group and are symmetrically arranged on the second guide column 17;

[0073] A turning shovel 19 is provided on the moving block 18;

[0074] A first magnet 20 is disposed in the moving block 18; and

[0075] There are two groups of No. 2 magnets 21 , and each group of No. 2 magnets 21 is arranged on the inner wall of the drying box 1 in a stepped manner. The No. 2 magnets 21 and the No. 1 magnets 20 meet and attract each other.

[0076] It should be noted that this embodiment is not limited to the above-mentioned No. 1 magnet 20 and No. 2 magnet 21 to adjust the position of the moving block 18. Electromagnets or permanent magnets can also be used instead, which are not listed here one by one.

[0077] When the electric telescopic rod 12 is continuously extended and retracted by the controller 3 to control the reciprocating movement of the gauze 16 in the vertical direction, the No. 2 guide column 17 and the moving block 18 can be controlled to move upward synchronously, and the No. 1 magnet 20 successively meets and attracts the No. 2 magnet 21 at different positions, thereby driving the moving block 18 and the turning shovel 19 to move along the No. 2 guide column 17, thereby turning over the magnesium hydroxide flame retardant on the surface of the gauze 16, ensuring that all surfaces of the magnesium hydroxide flame retardant can be dried by the hot air flow, further improving the drying effect of the magnesium hydroxide flame retardant.

[0078] How this application works:

[0079] The magnesium hydroxide flame retardant is poured into the drying box 1 and placed on the gauze 16. The electric telescopic rod 12 is continuously extended and retracted by the controller 3, driving the sliding seat 13 to reciprocate in the horizontal direction, so that under the action of the push rod 14, the top rod 7 and the gauze 16 can be driven to reciprocate, so that the magnesium hydroxide flame retardant on the screen is in a shaking state, thereby driving the No. 1 winding disk 9 to rotate and rewind the belt under the sliding cooperation between the No. 1 damping strip 8 and the No. 2 damping strip 10, thereby driving the No. 1 winding disk 9 to rotate and rewind the belt, thereby driving the piston 29 to reciprocate along the vacuum box 23, thereby drawing the outside air into the vacuum box 23 and It is input into the heating box 22 for heating treatment, and finally the hot air flow can be blown from the drying seat 6 to the magnesium hydroxide flame retardant on the gauze 16 to realize the drying treatment of the magnesium hydroxide flame retardant. In this process, the external air flow is input into the vacuum box 23 to drive the rotor 26 to rotate, thereby driving the No. 2 winding disk 27 to rotate synchronously to rewind the belt, and under the action of the spring 2, drives the drying seat 6 to reciprocate along the No. 1 guide column 5, thereby realizing the drying treatment of the magnesium hydroxide flame retardant at different positions, further improving the drying effect of the magnesium hydroxide flame retardant. When the electric telescopic rod 12 is continuously extended and retracted by the controller 3 to control the reciprocating movement of the gauze 16 in the vertical direction, the No. 2 guide column 17 and the moving block 18 can be controlled to move upward synchronously, and the No. 1 magnet 20 successively meets and attracts the No. 2 magnet 21 at different positions, thereby driving the moving block 18 and the turning shovel 19 to move along the No. 2 guide column 17, thereby turning over the magnesium hydroxide flame retardant on the surface of the gauze 16, ensuring that all surfaces of the magnesium hydroxide flame retardant can be dried by the hot air flow, further improving the drying effect of the magnesium hydroxide flame retardant.
