Detailed implementation manners

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Please refer to Figures 1-4 , the present utility model provides a chemical additive feeding device, including a feeding box 1 which can prevent external factors from affecting chemical additives. The bottom end of the feeding box 1 is provided with support feet 2 to increase the overall height of the feeding box 1, making it convenient for discharging materials at the lower end. A control panel 3 is installed on the outside of the feeding box 1 to make it more convenient for staff to operate. Cavities 4 are symmetrically arranged on both sides of the feeding box 1, so as to reduce the overall weight and achieve the effect of cost saving. It is convenient to place tools inside the cavities 4, making the functionality better.

[0027] At the upper end of the feeding box 1, there is a funnel-shaped grinding cavity 8, and the inner wall of the grinding cavity 8 is arranged in a corrugated shape to facilitate the grinding work. Inside the grinding cavity 8, there is a funnel-shaped screening and grinding cone 9. The whole screening and grinding cone 9 is arranged in a perforated shape. The distance between the outer side of the screening and grinding cone 9 and the inner wall of the grinding cavity 8 gradually decreases, so that the lumps can gradually become smaller and form a powder shape, making the grinding effect better. On the inner side of the screening and grinding cone 9, a plurality of stirring rods 12 are symmetrically arranged. Under the action of the stirring rods 12, the additives stored inside can be stirred, making the feeding through the screening and grinding cone 9 more rapid. And at the bottom end of the screening and grinding cone 9, there is a connecting block 10 to facilitate the force-driven rotation work. In the middle of the grinding cavity 8, a rotating shaft 11 is connected through a bearing, and the bottom end of the rotating shaft 11 is connected to the connecting block 10. At the top of the feeding box 1, a first motor 6 is installed and connected to the rotating shaft 11. The first motor 6 drives the rotating shaft 11 to make the screening and grinding cone 9 rotate, so as to grind the additives in cooperation with the inner wall of the grinding cavity 8, thereby avoiding the influence of large additives in the chemical additives on the subsequent reaction rate, avoiding the problem of incomplete reaction, and timely dealing with it to prevent the waste of working time in subsequent processing. At the upper end of the grinding cavity 8, there is a feed port 5 passing through the feeding box 1 to add chemical additives into the screening and grinding cone 9.

[0028] A hopper-shaped blanking box 15 is connected to the bottom of the feeding box 1. Under the action of the blanking box 15, in the case where the weight of the materials received at one time is insufficient, continuous feeding can be carried out and then output together, making the chemical reaction effect better. A semi-circular rotating groove 14 is provided at the connection between the blanking box 15 and the feeding box 1. The rotating groove 14 can completely cover a material receiving groove 18, facilitating blanking so that the entire material receiving groove 18 can be accommodated, preventing the auxiliary agent from running out from the outside. Moreover, the blanking port 13 at the bottom of the grinding cavity 8 penetrates through the rotating groove 14 for blanking work, enabling the ground auxiliary agent to enter the material receiving groove 18. And electromagnetic valves 17 are installed at both the blanking port 13 and the bottom blanking port of the blanking box 15. Installing the electromagnetic valve 17 at the blanking port 13 can close the blanking after the quantity received inside the material receiving groove 18 reaches the set value, making the control of the material receiving effect better and more accurate. A rotating roller 16 is installed inside the rotating groove 14 and fits with its inner wall to prevent the auxiliary agent inside from running out from the gap when the material receiving groove 18 rotates under force. Fixed rods 111 are provided on both sides of the rotating roller 16 and are connected to the feeding box 1 through bearings. A second motor 7 is installed outside the feeding box 1 and is connected to the fixed rod 111. The second motor 7 can quickly drive the fixed rod 111 to make the rotating roller 16 rotate, making the operation more automated. Inside the rotating roller 16, the material receiving grooves 18 are symmetrically arranged inwards in groups of two, enabling continuous weighing of the weight of the auxiliary agent and making the weighing rate faster. A receiving plate 19 is connected to the inside of the material receiving groove 18 through a pressure sensor 110. Under the action of the receiving plate 19, the auxiliary agent can be received, preventing the auxiliary agent from directly falling onto the pressure sensor 110. Then, under the downward thrust of the receiving plate 19, the pressure sensor 110 receives a downward pressure, thereby weighing the falling weight and avoiding manual weighing, making the work efficiency higher.

[0029] Working principle: When in use, first connect the control panel 3, the first motor 6, the second motor 7, the electromagnetic valve 17 and the pressure sensor 110 to an external power source. Then, input the chemical auxiliary agent into the screening and grinding cone 9 inside the feeding box 1 through the feeding port 5. And the first motor 6 drives the screening and grinding cone 9 to rotate through the rotating shaft 11, so that the auxiliary agent passes through the leakage holes inside the screening and grinding cone 9 and contacts the inner wall of the grinding cavity 8 downward, and under the action of the rotation of the screening and grinding cone 9, the auxiliary agent is ground under force and falls onto the material receiving groove 18 inside the rotating roller 16 through the blanking port 13. Under the action of the receiving plate 19, a pressure is applied to the pressure sensor 110, thereby weighing the weight. After the pressure sensor 110 reaches the set value, the second motor 7 drives the rotating roller 16 to rotate in the rotating groove 14, so that the material receiving groove 18 pours the auxiliary agent downward into the blanking box 15 for blanking, thus completing the work.
