[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The chemical safety feeding device involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0019] Embodiment 1:

[0020] like Figure 1-3 As shown, a safe feeding device for chemical industry comprises a feeding hopper 1, a feeding mechanism 3 is arranged inside the feeding hopper 1, feeding ports 4 are provided on both sides of the top of the feeding hopper 1, a threaded sealing cover 5 is sleeved on the inner thread of the feeding port 4, an annular mounting groove is provided on the outer wall of the threaded sealing cover 5, a No. 1 sealing ring 6 is fixedly connected inside the annular mounting groove, a No. 2 sealing ring 7 is fixedly inlaid inside the feeding port 4, the inner wall of the No. 2 sealing ring 7 is movably sleeved on the outer wall of the No. 1 sealing ring 6, a handle 8 is fixedly connected to the top of the threaded sealing cover 5, and a flange 2 is fixedly connected to the bottom of the feeding hopper 1.

[0021] In this embodiment, by setting the flange 2, it is convenient to install the bottom of the feeding hopper 1 on the feeding pipe of the reactor. By setting the feeding port 4, the material can be first put into the feeding hopper 1, and then the threaded sealing cover 5 can be screwed on the inside of the feeding port 4. The threaded sealing cover 5 drives the outer wall of the No. 1 sealing ring 6 to move to the inside of the No. 2 sealing ring 7. The cooperation of the No. 1 sealing ring 6 and the No. 2 sealing ring 7 is utilized to increase the sealing performance between the threaded sealing cover 5 and the feeding port 4.

[0022] Embodiment 2:

[0023] like Figure 1-3As shown, the feeding mechanism 3 includes a closed baffle plate 36, the outer wall of the closed baffle plate 36 is movably sleeved under the inner wall of the feeding hopper 1, the top of the closed baffle plate 36 is cone-shaped, and the top of the closed baffle plate 36 is symmetrically fixedly connected with two connecting rods 35, and the top of the feeding hopper 1 is symmetrically fixedly sleeved with two sealing sleeves 37, the outer walls of the two connecting rods 35 are movably sleeved inside the two sealing sleeves 37, the top of the feeding hopper 1 is fixedly connected with a protective cover 31, and the interior of the protective cover 31 is slidably connected with an adjustment plate 34, the top ends of the two connecting rods 35 extend to the inner cavity of the protective cover 31 and are fixedly connected to the two sides of the bottom of the adjustment plate 34, and the interior of the protective cover 31 is provided with a screw rod 33, the bottom end of the screw rod 33 is rotatably connected to the middle part of the top of the feeding hopper 1, the middle part of the adjustment plate 34 is threadedly sleeved on the outer wall of the screw rod 33, and the top end of the screw rod 33 extends to the top of the protective cover 31 and is fixedly connected with a knob 32.

[0024] In this embodiment, when the material inside the hopper 1 is fed into the reactor, the staff can rotate the screw rod 33 through the knob 32, and the screw rod 33 drives the adjustment plate 34, the connecting rod 35 and the closed baffle plate 36 to move upward. By setting the sealing sleeve 37, the sealing between the connecting rod 35 and the top of the hopper 1 is increased. When the closed baffle plate 36 moves upward to the top of the inner cavity of the hopper 1, the space above the inner cavity of the hopper 1 is larger than the space below. At the same time, since the top of the closed baffle plate 36 is cone-shaped, the material above the closed baffle plate 36 will slide down and be put into the reactor for chemical reaction. At this time, since the feeding port 4 of the hopper 1 is sealed by the threaded sealing cover 5, the harmful gas generated in the reactor cannot be dispersed to the outside through the hopper 1.

[0025] In summary, if Figure 1-3 As shown, this kind of safe feeding device for chemical industry, when in use, first fix the flange plate 2 at the bottom of the feeding hopper 1 to the feeding pipe of the reactor, when performing the feeding operation, first remove the threaded sealing cover 5 by screwing, then put the chemical material into the feeding hopper 1 through the feeding port 4, and block the material by the closed material baffle plate 36, so that the material is stored inside the feeding hopper 1, and then the threaded sealing cover 5 is screwed on the feeding port 4 to close the feeding port 4. At this time, the staff screws the screw 33 through the knob 32, and the screw 33 drives the adjustment plate 34 to move upward inside the protective cover 31. While moving, the adjustment plate 34 drives the closed material baffle plate 36 to move upward through the two connecting rods 35. At this time, the space below the inside of the feeding hopper 1 is opened, and the material inside the feeding hopper 1 is downwardly put into the reactor for chemical reaction.
