[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The embodiment of the utility model discloses a raw material mixing device with a gas purification structure.

[0023] The utility model provides Figure 1-3 The raw material mixing device with a gas purification structure shown in the figure comprises a mixing barrel 1, a first through hole is formed on the top of the mixing barrel 1, a first sleeve 2 is arranged above the first through hole, a second sleeve 3 is fixedly sleeved inside the upper end of the first sleeve 2, a connecting mechanism is arranged on the side wall of the second sleeve 3 and connected to the mixing barrel 1 through the connecting mechanism, a second through hole is formed on the top of the second sleeve 3, a one-way blocking mechanism is penetrated inside the second through hole, an exhaust fan 4 is fixedly arranged on the top of the mixing barrel 1, and air guide pipes 5 are fixedly connected to both ends of the exhaust fan 4, and the mixing barrel 1 is provided with a second through hole. A mounting frame 6 is fixedly provided on one side of the refining barrel 1, and a gas purifier 7 is fixedly provided on the top of the mounting frame 6. The other ends of the two air guide pipes 5 respectively penetrate into the interior of the mixing barrel 1 and the gas purifier 7. By utilizing the one-way blocking mechanism, when the gas inside the mixing barrel 1 is less and a negative pressure is formed, the air outside the mixing barrel 1 can be pumped into the interior of the mixing barrel 1 through the first through hole, thereby ensuring the normal operation of the exhaust fan 4, so that even if the gas generated inside the mixing barrel 1 is less, it can be pumped into the interior of the gas purifier 7 for purification.

[0024] like Figure 2As shown, the connecting mechanism includes two telescopic rods 8, two first springs 9 and two connecting plates 10. The two telescopic rods 8 are fixedly arranged on the top of the mixing barrel 1 and the other ends are fixedly connected to the corresponding connecting plates 10 respectively. The upper surfaces of the two connecting plates 10 are fixedly connected with L-shaped rods 11 rotatably connected to the outer wall of the second sleeve 3. The two first springs 9 are movably sleeved on the rod walls of the corresponding telescopic rods 8. The two ends of each first spring 9 are fixedly connected to the top of the mixing barrel 1 and the lower surface of the corresponding connecting plate 10. By utilizing the two first springs 9, the corresponding connecting plate 10 can be pulled by the elastic force of the two first springs 9, thereby ensuring that the lower end of the first sleeve 2 is in contact with the top of the mixing barrel 1.

[0025] like Figure 3 As shown, the one-way blocking mechanism includes a movable rod 12, a movable plate 13, a sealing gasket 14 and a second spring 15. The movable rod 12 is movably arranged inside the second through hole and fixedly sleeved with the movable plate 13.

The second spring 15 is movably sleeved on the rod wall of the movable rod 12 and its two ends are respectively fixedly connected to the top inner wall of the second sleeve 3 and the surface of the movable plate 13. By utilizing the set second spring 15, the elastic force of the second spring 15 can pull the movable plate 13 to drive the sealing gasket 14 to keep in close contact with the bottom of the second sleeve 3, thereby avoiding air leakage. When negative pressure is formed inside the mixing barrel 1 during the operation of the exhaust fan 4, external air can be drawn into the mixing barrel 1, thereby achieving continuous operation of the exhaust fan 4.

[0026] like Figure 2 As shown, the rod walls of the two L-shaped rods 11 are movably sleeved with torsion springs 16, and both ends of each torsion spring 16 are fixedly connected to the outer wall of the second sleeve 3 and the rod wall of the corresponding L-shaped rod 11. By utilizing the set torsion springs 16, after the second sleeve 3 is pulled upward, the elastic force of the two torsion springs 16 can drive the first sleeve 2 and the second sleeve 3 to maintain a horizontal state, thereby facilitating the replacement of the sealing gasket 14.

[0027] like Figure 2 As shown, a sealing ring 17 is fixedly provided at the bottom of the first sleeve 2, and the sealing ring 17 is in contact with the top outer wall of the mixing barrel 1. The sealing ring 17 can effectively ensure the sealing between the bottom of the second sleeve 3 and the top of the mixing barrel 1.

[0028] like Figure 3 As shown, a sleeve 18 is fixedly provided on the upper surface of the sealing gasket 14. The sleeve 18 is movably sleeved on the lower end rod wall of the movable rod 12 and fixedly connected to the movable rod 12 by bolts. The sealing gasket 14 is installed using the sleeve 18 and bolts, and can be disassembled and replaced after the sealing gasket 14 is worn.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
