Description

Technical Field

[0001] This utility model relates to the field of yellow phosphorus production and processing technology, specifically to an automatic raw material proportioning and feeding device for yellow phosphorus production. Background Technology

[0002] Yellow phosphorus is an important basic industrial raw material, mainly used to prepare phosphoric acid, phosphides, and phosphates, and is widely used in fertilizers, pesticides, feed, food processing, construction, pharmaceuticals, electronics, and many other fields. Currently, the main industrial method for producing yellow phosphorus is the electric furnace method, where a reduction reaction occurs at a high temperature of 1400℃. The phosphorus vapor and furnace dust are cooled and washed together to obtain the yellow phosphorus product.

[0003] In the production and processing of yellow phosphorus, the dried and screened raw materials (phosphate rock, coke, and silica) need to be lifted into the raw material silo or directly fed into the blast furnace for processing. Currently, the phosphate rock smelting batching system generally uses a metering hopper method. Metering hopper batching involves manually adjusting the opening of the discharge valve, resulting in considerable arbitrariness in the batching process. A main conveyor belt transports the ore, and above this belt are several metering hoppers, each corresponding to a different mass of batching material. During the conveyor belt transport, it is required to distribute these batching materials as evenly as possible onto the conveyor belt, ensuring that the batching materials and ore are mixed in a roughly consistent ratio to achieve the optimal phosphate rock smelting effect. However, due to the different weights and volumes required by the process, to ensure that these batching materials are evenly distributed on the ore conveyor belt, the current process relies on manual adjustment of the hopper outlet diameter based on experience to control the flow rate of the batching materials from the metering hopper outlet, aiming to ensure that the ore and batching materials are mixed as evenly as possible. However, since the weight of the ingredients in each batching hopper is inconsistent, the conveying speed of the ingredients must be adjusted by manually changing the outlet diameter of the metering hopper. It is difficult to keep the outlet diameter completely consistent with the amount of ore on the conveyor belt. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides an automatic raw material proportioning and feeding device for yellow phosphorus production that requires less manual intervention, has high feeding efficiency, and provides accurate proportions of each raw material.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic proportioning and feeding device for raw materials used in the production of yellow phosphorus, comprising a silo mechanism, a weighing mechanism, a mixing mechanism, and a control panel. The silo mechanism includes a No. 1 silo, a No. 2 silo, and a No. 3 silo. The No. 1 silo has a cylindrical structure, with a feeding hopper installed on the top surface and a conical hopper structure on the bottom surface. A feeding pipe is installed on the bottom surface, and a feeding mechanism is provided on one side of the feeding pipe.

[0006] The feeding mechanism includes a feeding pipe, a support, a spiral feeding shaft, and a feeding motor. The feeding pipe has an inlet end and a outlet end at its two ends, respectively. An upward-opening receiving pipe is installed on the inlet end, which is connected to the feeding pipe of the first hopper. The outlet end has a downward-opening outlet.

A material hole corresponding to the feeding pipe of the weighing bin is opened on the bottom surface of the connecting section, and is connected to the feeding pipe of the weighing bin through a telescopic hose.

[0009] The mixing mechanism includes a mixing tank, a stirring motor, and a feeding assembly. The mixing tank is located on one side of the weighing hopper. An inlet pipe is installed on the top surface of the mixing tank, and a discharge pipe with an electric gate valve is installed at the bottom. The outlet of the discharge pipe is connected to the material inlet of the yellow phosphorus electric furnace. The stirring motor is installed in the middle of the top surface of the mixing pipe, and its drive end extends into the tank body. A stirring shaft is fixedly connected to the drive end.

[0031] from Figure 3As can be seen, the mixing mechanism includes a mixing tank 12, a stirring motor 13, and a feeding group 14. The mixing tank 12 is located on one side of the weighing bin 10. An inlet pipe is installed on the top surface of the mixing tank 12, and a discharge pipe with an electric gate valve is installed at the bottom.

[0033] like Figure 1-4 As shown, the specific structure and implementation method are as shown in Example 1, except that the feeding pipe 11 is provided with a scraping group.

[0034] from Figure 4 As can be seen, the scraping assembly includes a groove 16, a transmission screw assembly 17, and a feeding scraper 18, which are opened on the side plate of the feeding pipe 11. The transmission screw assembly 17 is installed on the side plate of the feeding pipe 11. The top surface of the nut seat of the transmission screw assembly 17 is at the same horizontal position as the groove 16. The motor of the transmission screw assembly 17 is electrically connected to the control panel 1 through a wire. The shape of the feeding scraper 18 is adapted to the inner side wall of the feeding pipe 11. One side of its top surface extends out of the groove 16 and is fixedly connected to the nut seat of the transmission screw assembly 17.

[0035] See Figure 4 A dustproof brush 21 is installed inside the slide groove 16.

[0036] See Figure 3 Three sets of vibration motors 19 are installed on the outer wall of the weighing chamber 10 to vibrate the chamber body of the weighing chamber 10, causing the raw materials covered on the side wall to slide off. The vibration motors 19 are connected to the control panel 1 through wires.

The scraping surface of the scraper 20 is in contact with the inner side wall of the tank, and the mounting surface is connected and fixed to the shaft of the stirring shaft 15 through the mounting rod.

[0038] During operation, the crushed and ground raw materials (phosphate rock, coke, and silica) are first placed into hopper 2, hopper 3, and hopper 4 in sequence. After placement, the control panel 1 opens the feeding mechanism below hopper 2 to send the phosphate rock into the feeding pipe 11. With the help of the discharging vibration motor, the phosphate rock slides into the weighing hopper 10. The weighing device 9 transmits the weight information to the control panel 1 in real time. When the preset value range is reached, the feeding mechanism is closed, and the scraper group in the feeding pipe 11 is opened to scrape the remaining phosphate rock in the pipe into the weighing hopper 10. At this time, the electric gate valve of the weighing hopper 10 is opened to allow the phosphate rock powder to enter the mixing tank 12. At the same time, the vibration motor 19 is turned on to shake off the remaining phosphate rock. After the phosphate rock enters the mixing tank 12, the stirring motor 13 is started to stir. While stirring, the mixing scraper 20 scrapes off the material covering the side wall.

[0039] After the phosphate rock is weighed and fed, the feeding mechanism under the No. 2 silo 3 is opened. The coke is fed, weighed, and metered according to the previous steps and then enters the mixing tank 12 to be stirred and mixed with the phosphate rock. After the coke is fed, the silica is fed, weighed, and metered according to the previous steps and then enters the mixing tank 12 to be mixed and stirred. After the preset stirring time is reached, the electric gate valve on the mixing tank 12 is opened to allow the mixed raw materials to enter the yellow phosphorus electric furnace for yellow phosphorus preparation.
