[0031] Example 1:
[0032] See also Figure 1 、 Figure 2 and Figure 6 The utility model provides a technical solution: a chemical safety feeding device, comprising a funnel 2 installed on a reactor 1, the discharge port of the funnel 2 is aligned with the feed port of the reactor 1, a rotating shaft 3 is horizontally penetrated on the side wall of the funnel 2, the rotating shaft 3 is rotatably connected to the funnel 2, a blade 4 is fixedly connected to the rotating shaft 3, the blade 4 is located in the funnel 2 and extends upward along the central axis of the funnel 2, a driving assembly is installed on the funnel 2, and the driving assembly can drive the rotating shaft 3 to rotate reciprocatingly.
[0033] In this solution, the lower end of the funnel 2 is threadedly connected to the feed port of the reactor 1, which facilitates the removal and installation of the funnel 2 from the reactor 1. The tip of the blade 4 protrudes from the horizontal plane of the funnel 2, making it convenient to cut open the bag containing the powdered chemical raw materials.
[0034] Working principle and usage:
[0035] Step 1: The bag containing the powdered chemical raw materials is carried to the upper end of the funnel 2 by crane or manpower, and the bottom of the bag completely covers the upper end of the funnel 2. This reduces the amount of powdered chemical raw materials floating in the air during the feeding process.
[0036] Step 2: The drive assembly drives the shaft 3 to rotate back and forth, which in turn drives the blade 4 to rotate. The blade 4 cuts through the bag containing the powdered chemical raw materials during the rotation, eliminating the need for staff to manually untie the bag.
[0037] Step 3: The powdered chemical raw materials flow out from the cut hole in the bag under the action of their own gravity and enter the reactor 1 through the funnel 2.
[0038] Step 4: After the feeding is completed, the bag is removed by crane or manually using a pole to reduce the dust inhaled by the staff when removing the bag and facilitate the next feeding.
[0039] Compared with the prior art, after the bag of powdered chemical raw materials is placed on the upper end of the funnel 2, there is no need to manually untie the bag opening, which reduces the dust and harmful gases generated during the feeding process and reduces the harm to the staff.
[0040] In this embodiment: one end of the rotating shaft 3 is fixedly connected to the first gear 6, and the driving assembly includes a cylinder 7, one end of the cylinder 7 is fixedly installed on the top of the reactor 1, and the other end extends upward and is fixedly connected to a rack 8 that meshes with the first gear 6.
[0041] This solution also includes a controller, model OHR-PR10, and a cylinder 7, model 86K-1R-63.586. Cylinder 7 is electrically connected to the controller. In the initial state of blade 4, blade 4 is vertically upward, with an angle of 60 degrees between blade 4 and the side wall of funnel 2. Cylinder 7 and controller are both powered on.
[0042] Working principle and usage:
[0043] Step 1: The controller controls the upper end of the cylinder 7 to retract downward, and the rack 8 moves downward, driving the first gear 6 and the rotating shaft 3 to rotate 60 degrees clockwise. The blade 4 rotates 60 degrees clockwise along with the rotating shaft 3, causing the blade 4 to cut the bottom of the bag containing the powdered chemical raw materials.
[0044] Step 2: The controller controls the upper end of the cylinder 7 to extend upward, and the rack 8 moves upward accordingly, driving the first gear 6 and the rotating shaft 3 to rotate 120 degrees counterclockwise. The blade 4 also rotates 120 degrees counterclockwise along with the rotating shaft 3. This allows the blade 4 to further cut the bottom of the bag containing the powdered chemical raw materials, speeding up the feeding speed.
[0045] Step 3: The controller controls the upper end of the cylinder 7 to retract downward, and the rack 8 moves downward, driving the first gear 6 and the shaft 3 to rotate 60 degrees clockwise. The blade 4 rotates 60 degrees clockwise along with the shaft 3, so that the blade 4 is reset and convenient for the next use.
[0046] Step 4: Repeat steps 1 to 3 to break up the powdered chemical raw materials while they are falling into the reactor 1 , so as to prevent the agglomerated chemical raw materials from clogging the funnel 2 .
[0047] In this embodiment, a rubber ring 9 is fixedly connected to the feed port of the funnel 2 .

A first roller 11 is fixedly connected to the first connecting rod 10, and a first transmission assembly is installed between the first connecting rod 10 and the rotating shaft 3. When the rotating shaft 3 rotates, the first connecting rod 10 is driven by the first transmission assembly, and the first roller 11 rotates with the first connecting rod 10. When agglomerated chemical raw materials pass through the hopper 2, they fall onto the first roller 11. As the first roller 11 rotates, the agglomerated chemical raw materials are continuously broken up, reducing the risk of clogging the hopper 2.

A second roller 16 is fixedly connected to the second connecting rod 15, and a second transmission assembly is installed between the second connecting rod 15 and the first connecting rod 10. When the first connecting rod 10 rotates, the first roller 11 rotates along with the first connecting rod 10, and the second connecting rod 15 is driven to rotate by the second transmission assembly, and the second roller 16 rotates along with the second connecting rod 15.

[0059] In this embodiment, the upper end of the blade 4 is triangular in shape, and both sides have sharp edges.
[0060] In this solution, the upper end of the blade 4 is triangular in shape, and both sides are sharp blades, which makes it easier for the blade 4 to cut through the bottom of the bag containing the powdered chemical raw materials.
