Description

Technical Field

[0001] This utility model relates to the field of yellow phosphorus production technology, and in particular to an automated feeding device in a continuous yellow phosphorus production line. Background Technology

[0002] Yellow phosphorus is an important chemical raw material, mainly used to prepare phosphoric acid, pesticides, and flame retardants. It uses phosphate rock, silica, and coke as the main raw materials, which are mixed evenly in a certain proportion. The mixed raw materials are then fed into an electric furnace and undergo a reduction reaction at a high temperature of 1350 to 1450°C to generate phosphorus vapor and slag. The phosphorus vapor is condensed to form yellow phosphorus, which is deposited in the condensation pool.

[0003] For example, Chinese patent CN221894173U discloses a yellow phosphorus quantitative feeding device, including a main base. A weighing end base is fixedly connected to the middle of the upper side wall of the main base near the rear. A weighing end assembly is bolted to the middle of the upper surface of the weighing end base near the front. The weighing end assembly includes a fixed base plate. A weighing sensor is bolted to the middle of the upper side wall of the fixed base plate. A weighing pan is bolted to the upper side wall of the weighing sensor. This utility model utilizes an electric screw to drive the feeding hopper to move back and forth. When the feeding hopper moves backward, the bottom groove slides into the weighing pan. Because the bottom groove is lower at the front and higher at the back, the weighing pan is completely lifted during the backward movement of the feeding hopper. The weight of the feeding hopper is measured by the weighing sensor, eliminating the need for manual weighing of the yellow phosphorus, making it more convenient, faster, and safer.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its application, such as: the weighing and feeding are performed in separate steps, resulting in interruptions and poor continuity during the feeding process, leading to low feeding efficiency; the process of adding yellow phosphorus raw material into the downward feeding hopper will stir up dust, and since yellow phosphorus raw material contains toxic substances, its release into the external environment will pollute the environment and harm the health of workers. Therefore, we propose an automated feeding device for a continuous yellow phosphorus production line. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an automated feeding device for a continuous yellow phosphorus production line. This device solves the problems of separate weighing and feeding processes, which result in interruptions, poor continuity, and low feeding efficiency. Furthermore, the process of feeding yellow phosphorus raw materials into the hopper generates dust, and the presence of toxic substances in the raw materials can pollute the environment and harm workers if released into the environment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automated feeding device for a continuous yellow phosphorus production line includes an installation frame, hollow shafts rotatably mounted on both the left and right sides of the installation frame, a connecting seat fixedly mounted between the two hollow shafts, a transfer tank provided on both the upper and lower sides of the connecting seat, and a hopper fixedly mounted on the top of the installation frame.

[0009] A sleeve, which passes through and is fixedly installed in the middle of the connecting seat, and pressure sensors are fixedly installed on the inner walls of both the upper and lower ends of the sleeve.

[0010] A drive assembly, which is mounted on a mounting frame and is used to drive the hollow shaft to rotate;

[0011] A discharge assembly, which is installed on a hopper and is used to discharge the material inside the hopper into a transfer tank.

[0012] Preferably, the driving component includes:

[0013] The motor is fixedly mounted on the bottom inner wall of the mounting frame. A second synchronous pulley is fixedly mounted on the output end of the mounting frame. A first synchronous pulley is fixedly mounted on the outer wall of one of the hollow shafts. A synchronous belt is sleeved between the outer walls of the first and second synchronous pulleys.

[0014] Preferably, the unloading assembly includes:

[0015] A star-shaped unloader is fixedly installed at the lower port of the hopper. A telescopic feeding pipe is fixedly installed at the bottom of the star-shaped unloader. A first electric push rod is fixedly installed between the upper and lower ends of the outer wall of the telescopic feeding pipe. The outer diameter of the telescopic feeding pipe is smaller than the inner diameter of the turnover tank opening. The telescopic feeding pipe is aligned vertically with the turnover tank opening.

[0016] Preferably, a disc-shaped tube is fixedly installed on the inner wall of the connecting seat.

[0017] Preferably, the detection ends of both pressure sensors protrude from the port of the sleeve.

[0018] Preferably, multiple connectors are fixedly installed on the outer walls of adjacent sides of the two turnover tanks, and the other ends of the multiple connectors are all through and slidably connected to the connecting seat.

[0019] Preferably, a gate is slidably installed through the front side of the openings of both of the turnover tanks.

[0020] Preferably, a second electric push rod is fixedly installed on the right side of the opening of each of the two turnover tanks, and the movable ends of the two second electric push rods are respectively fixedly connected to the front side of the two gates.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By controlling the extension of the first electric push rod, the telescopic feeding pipe extends and is inserted into the opening of the upper turnover tank, so that when the yellow phosphorus raw material is put into the turnover tank, the dust of the yellow phosphorus raw material will not escape to the outside.

[0023] Second, by setting up two symmetrically installed turnover tanks, one turnover tank can be used to add raw materials to the electric furnace while the other turnover tank is used to fill and weigh yellow phosphorus raw materials. The two turnover tanks can be controlled to alternately circulate through the drive component, so that weighing and adding yellow phosphorus raw materials can be carried out continuously, thereby improving the feeding efficiency.

[0024] Third, by storing yellow phosphorus raw materials in a turnover tank, the toxic substances in the yellow phosphorus raw materials can be prevented from escaping into the air. Then, coolant is injected into the disc tube by a chiller, and then the temperature of the turnover tank is reduced through heat transfer, thereby reducing the internal temperature of the turnover tank and preventing the yellow phosphorus raw materials from thermally deliquescing.

[0067] Pressure sensor 18: It is a strain gauge pressure sensor, which is fixed to the inner wall of sleeve 16 by a metal bracket and bolts and is installed vertically.

[0068] Working principle:

[0069] First, control the extension of the second electric push rod 13 on the upper side, so that the movable end of the second electric push rod 13 drives the gate 14 to move forward. Then the opening blocked by the gate 14 will open. Next, control the extension of the first electric push rod 6, and then the telescopic feeding pipe 12 will extend and be inserted into the opening of the upper turnover tank 3, so that when the yellow phosphorus raw material is put into the turnover tank 3, the dust of the yellow phosphorus raw material will not escape to the outside.

[0070] The second step is to start the star-shaped unloader 11 so that the yellow phosphorus raw material in the hopper 1 is transported to the upper turnover tank 3 through the star-shaped unloader 11 and the telescopic feeding pipe 12. During the loading process, the pressure applied to the turnover tank 3 can be detected by the pressure sensor 18 on the upper side. The mass of the yellow phosphorus raw material put into the turnover tank 3 can be known by the pressure difference between the front and the back.

[0071] Third, under the pressure of the upper turnover tank 3, the upper connector 17 slides along the connecting seat 4, and then the bottom of the turnover tank 3 approaches the connecting seat 4. Then, by starting the chiller, the coolant is delivered to one end of the coiled tube 15 through a hose, and then flows back to the chiller through the other end of the coiled tube 15 and another hose. During this process, the temperature of the surface of the connecting seat 4 decreases, and under the action of heat transfer, the temperature of the turnover tank 3 decreases, thereby reducing the temperature of the yellow phosphorus raw material inside the turnover tank 3.

[0072] Fourth step: After the yellow phosphorus raw material in the upper turnover tank 3 is loaded, the second electric push rod 13 on the upper side is retracted to reseal the opening of the turnover tank 3 with the gate 14 and close the star-shaped unloader 11. Then, the motor 9 is started to drive the second synchronous pulley 8 to rotate. Then, through the transmission of the synchronous belt 7 and the first synchronous pulley 5, the first synchronous pulley 5 drives the hollow shaft 10, the connecting seat 4 and the two turnover tanks 3 to rotate together. When the two turnover tanks 3 are rotated 180°, the turnover tank 3 containing the yellow phosphorus raw material will be located at the bottom with the opening facing the direction. Then, the gate 14 sealing the turnover tank 3 can be opened to allow the yellow phosphorus raw material to fall into the electric furnace through the opening, thus completing the feeding and allowing the next process to proceed.

[0073] Fifth, when the yellow phosphorus raw material is fed into the electric furnace from the lower transfer tank 3, the yellow phosphorus raw material can be loaded and weighed again from the upper transfer tank 3 in the same way as in the second step. This can be done in a continuous manner to achieve continuous loading, weighing and feeding into the electric furnace.

[0074] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
