[0022] like Figure 1 , Figure 2 As shown, a double cone dryer safety protection device comprises a U-shaped guardrail 3 and guardrail guide support blocks 4 fixed on the support frames 2 on the left and right sides of the double cone dryer 1; the guardrail guide support block 4 is provided with a moving groove 41, a guide groove 42 and a positioning groove 43 connected with the guide groove 42, and the tails of both sides of the U-shaped guardrail 3 are provided with a support bracket 31 and a guide bracket 32, the support bracket 31 is located in the moving groove 41, and the guide bracket 32 ​​is located in the guide groove 42. The U-shaped guardrail 3 can be used to provide a hard isolation effect for the operator to prevent the operator from being mechanically injured when the equipment is running; it occupies a small space and does not affect the production operation of the double cone dryer 1 discharging materials; through the cooperation between the support bracket 31 and the moving groove 41, and the cooperation between the guide bracket 32 ​​and the guide groove 42 and the positioning groove 43, the operation is convenient and fast when in use.

[0023] A damper 5 is provided on a support bracket 31 on one side of the U-shaped guardrail 3. The damper 5 prevents the guardrail from falling too fast, reduces wear on the device, increases the service life of the device, and reduces the risk of accidental injury to staff during descent.

[0024] It is also provided with a proximity switch 6, which is at the same height as the positioning slot 43 on the guardrail guide support block 4, and the proximity switch 6 is interlocked with the double cone dryer 1. By sensing and detecting the U-shaped guardrail 3 through the proximity switch 6, the working state of the double cone dryer 1 can be better controlled to prevent the double cone dryer 1 from starting when the U-shaped guardrail 3 is not placed in a safe position, thereby preventing harm to personnel.

[0025] like Figure 3 As shown, the movable groove 41 is in the shape of a long hole, and the guide groove 42 is in the shape of an arc. The movable groove 41 in the shape of a long hole can not only fix the support bracket 31, but also enable the support bracket 31 to move forward and backward in the movable groove 41, so that the guide bracket 32 ​​falls into the positioning groove 43; the guide bracket 32 ​​can rotate in the guide groove 42, thereby adjusting the position of the U-shaped guardrail 3.

[0026] The guardrail guide support block 4 is located at a height of 1.2m±0.1m of the support frame 2.

[0027] A method of using a double cone dryer safety protection device is:

[0028] When the double-cone dryer 1 is used, the U-shaped guardrail 3 is manually lifted, and the guide bracket 32 ​​in the U-shaped guardrail 3 moves upward along the guide groove 42. When the guide bracket 32 ​​is located at the top of the guide groove 42, the U-shaped guardrail 3 is pulled forward, and the support bracket 31 moves forward along the moving groove 41. The guide bracket 32 ​​falls into the positioning groove 43, and the U-shaped guardrail 3 is in a horizontal state and starts to play a protective role. The proximity switch 6 detects that the U-shaped guardrail 3 sends a working signal to the double-cone dryer 1, and the double-cone dryer 1 can work at this time.

[0029] When loading and unloading, the U-shaped guardrail 3 is manually lifted and pushed backward, the support bracket 31 moves backward along the moving groove 41, and the guide bracket 32 ​​falls into the guide groove 42 and moves downward along the guide groove 42. The proximity switch 6 cannot detect that the U-shaped guardrail 3 sends a stop signal to the double cone dryer 1. At this time, the double cone dryer 1 cannot work. When the guide bracket 32 ​​falls to the bottom of the guide groove 42, loading and unloading can begin. In this process, the damper 5 can prevent the guardrail from falling too fast, reduce the wear of the device, increase the service life of the device, and reduce the risk of accidental injury to workers during descent.

[0030] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention.
