The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] A safety device for a pneumatic dual-shaft mixer according to an embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 4 As shown, a pneumatic double-shaft mixer safety device according to an embodiment of the utility model comprises a body 1, a feed port 2, a driving device 3, a protective cover 4, a rotating device 5, a water outlet 6 and a discharge port 7, wherein the feed port 2 is arranged on the body 1, the protective cover 4 is arranged on one side of the body 1, the driving device 3 comprises a driving assembly 31 and a bottom plate 32, wherein the bottom plate 32 is arranged on one side of the protective cover 4, the driving assembly 31 is arranged on the bottom plate 32, the rotating device 5 comprises a gear assembly 51 and a rotating shaft assembly 52, wherein, The gear assembly 51 is rotatably disposed in the protective cover 4, and the gear assembly 51 is connected to the driving assembly 31, the shaft assembly 52 is rotatably disposed in the body 1, and the shaft assembly 52 is connected to the gear assembly 51, the water outlet device 6 includes a water outlet assembly 61 and two ball valves 62, wherein the water outlet assembly 61 is disposed on the body 1, the two ball valves 62 are respectively disposed on the water outlet assembly 61, and the two ball valves 62 are respectively connected to the water outlet assembly 61, and the discharge port 7 is disposed at the bottom of one side of the body 1 away from the gear assembly 51.

[0025] Among them, it can be understood that the material enters the body 1 through the feed port 2, and the driving component 31 rotates to drive the gear component 51 to rotate and simultaneously drives the rotating component 52 to rotate synchronously. At the same time, the two ball valves 62 control the water outlet component 61 to discharge water, thereby achieving stirring of the material in the body 1.

[0026] Specifically, an air box is installed under the machine body 1. The air box is blown with high-pressure air by a Roots blower. After the material enters the machine body 1, it is first fluidized by the gasification effect of the air box at the bottom of the machine body 1, and then aerated and stirred by the action of the rotating component 52 in the machine body 1. Since the discharge port 7 is at the upper part of the machine body 1, the stirred material overflows from the discharge port 7. The material below the discharge port 7 is further stirred with the subsequent material entering the machine body 1 and then overflows from the discharge port 7. Since the material in the machine body 1 is fully fluidized and the material overflows the structure, the granular slag of the material will be deposited at the bottom of the machine body 1. When the mixer needs to be stopped after working for a certain period of time, it is cleared out from the slag removal port at the lower side of the machine body 1.

[0027] In one embodiment of the present invention, Figure 3 As shown, the driving assembly 31 includes a cycloidal pinwheel reducer 311, a coupling 312 and a motor 313, wherein the cycloidal pinwheel reducer 311 is arranged on the base plate 32, one end of the coupling 312 is connected to the output shaft of the cycloidal pinwheel reducer 311, and the other end passes through the protective cover 4 and is connected to the gear assembly 51, and the motor 313 is arranged on one side of the coupling 312, and the output shaft of the motor 313 is connected to the coupling 312.

[0028] It can be understood that the rotation of the motor 313 drives the cycloid reducer 311 to rotate, and at the same time drives the coupling 312 to rotate, thereby providing power for the rotation of the device.

[0029] In one embodiment of the present invention, Figure 3 As shown, the gear assembly 51 includes two rotating gears 511 , wherein the two rotating gears 511 are disposed in the protective cover 4 and the two rotating gears 511 are meshed, and one of the two rotating gears 511 is connected to the coupling 312 .

[0030] It can be understood that the two rotating gears 511 are driven to rotate by the rotation of the coupling 312 , and the protective cover 4 can protect the two rotating gears 511 .

[0032] It can be understood that the two rotating gears 511 rotate, and at the same time drive the two rotating shafts 521 and the multiple right-handed mixing paddles 522 to rotate synchronously to achieve the stirring of the material. At the same time, the directions of the two rotating shafts 521 are set in opposite directions, so as to achieve opposite rotation. On the two rotating shafts 521, multiple right-handed mixing paddles 522 with opposite rotation directions are respectively installed, which can effectively cause the material to tumble, shear and convect, thereby achieving an efficient mixing effect. At the same time, the spiral structure formed by the multiple right-handed mixing paddles 522 can not only stir the material during the mixing process, but also continuously transport the material to the discharge port 7, realizing the dual functions of mixing and transporting.

[0033] In one embodiment of the present invention, Figure 1As shown, the water outlet assembly 61 includes a support frame 611, two water pipes 612 and a water inlet pipe 613, wherein the support frame 611 is arranged on the body 1, and the support frame 611 is a hollow structure, the two water pipes 612 respectively pass through the support frame 611 and are arranged in the support frame 611, the water inlet pipe 613 is connected to the two water pipes 612, the two ball valves 62 are respectively connected to the two water pipes 612, and an inspection door 11 can be interactively arranged on the side of the body 1 away from the feed port 2.

[0034] Among them, it can be understood that water is fed into the two water pipes 612 through the water inlet pipe 613, the switch and flow rate of the water flow are controlled by two ball valves 62, and water can flow into the body 1 through the two water pipes 612.
