Yellow phosphorus is also an important raw material for industry. Modern industrial production of yellow phosphorus: generally can be divided into electric furnace method and blast furnace method. Compared with blast furnace method, electric furnace method has higher economic benefit and more mature industrial technology, and is widely used.

[0003] The main raw materials for yellow phosphorus production are phosphate rock, coke and silica, which are crushed into small particles and powder and mixed together, then enter the electric furnace from the hopper, and the mixture is easy to form blockage in the discharge port pipeline of the hopper. Some choose to add a hollow shaft motor in the hopper, such as application No. 201921478599.4 discloses a anti-blocking feeding mechanism for rotary kiln, which comprises a metal cylinder, a hollow shaft motor is fixed on the inner wall of the conical cover through bolts, and a plurality of grooves are arranged in the output shaft of the hollow shaft motor, a plurality of prismatic pipes are inserted into the inner wall of the grooves, and a screw blade is welded at the bottom of the side wall of the prismatic pipe. Such structure occupies the space inside the hopper, which is not convenient for operation in large storage space, and the effect is not good for some mineral powder. In addition, some vibration devices are arranged on the side wall of the hopper to solve part of the blockage problem, but there is no substantial effect on the blockage of the discharge port pipeline diameter of the hopper.

DETAILED DESCRIPTION

[0014] The present application will be further described below in combination with the drawings and examples. EXAMPLE

[0015] For example, Figure 1 , 2 ​As shown, the yellow phosphorus furnace feeding hopper with anti-blocking device includes a plurality of lower hoppers 1 arranged in a straight line, the upper ends of which are flush and the lower ends of which are located above the yellow phosphorus furnace, the lower ends of the lower hoppers 1 are connected to the yellow phosphorus furnace through variable pipes 2, a pull plate 3 is arranged between the variable pipes 2 and the lower hoppers 1, a circular support 4 is welded on the side wall of each variable pipe 2, and a pneumatic hammer 5 is installed on the circular support 4.

[0016] A gas pipe support 6 is arranged below the circular support 4, a gas-water separator 7 and a two-position three-way electromagnetic valve 8 are arranged on the gas pipe support 6, the gas outlet of the gas-water separator 7 is connected to the pneumatic hammer 5 through a hose 9, the gas inlet is connected to the electromagnetic valve 8, a group of signal line pipes 10 and gas pipes 11 are arranged on the inspection platform beside the lower hoppers 1, the gas pipes 11 are provided with a plurality of branch pipes 12 connected to the electromagnetic valve 8, the signal line pipes 10 are also branched into a plurality of signal lines connected to the electromagnetic valve 8, and the pneumatic hammer 5 and the electromagnetic valve 8 are connected to a controller 13.

[0017] A hollow inclined pipe 201 is arranged on the side wall of each variable pipe 2 and inclined downward, a monitoring support 202 is arranged on the top of the inclined pipe 201, the monitoring support 202 is a hollow cylinder, a flow monitor 203 is arranged in the monitoring support 202, the flow monitor 203 can move in the monitoring support 202, a support rod 204 is arranged vertically downward on the side wall of the monitoring support 202, the support rod 204 is hollow and provided with a gas blowing pipe at the bottom, and the gas blowing pipe works synchronously with the corresponding electromagnetic valve.

[0018] Working principle: open the pull plate, and the lower hopper starts to supply materials to the yellow phosphorus furnace through the variable pipe. During the material feeding process, after a certain period of time, the controller starts the electromagnetic valve to work, and then the pneumatic hammer works to knock the variable pipe area, so as to ensure the smoothness of the material by using impact force and vibration. At the same time, the flow detector independently monitors the single variable pipe, and when blockage is detected, the corresponding pneumatic hammer is started to knock and dredge.

[0019] The flow detector is in a daily working state of being suspended in the inclined pipe and not in contact with the inclined pipe wall. A soft sealing ring is arranged at the port of the inclined pipe. When the flow detector detects blockage, the flow detector is blown by the gas blowing pipe in the support rod, and Figure 3 As shown, the flow detector will be tilted upward and blown away from the variable pipe wall for a period of time. After the pneumatic hammer works, the flow detector slowly descends and resets to continue working. The pneumatic hammer avoids damaging the flow detector when vibrating, and ensures the accuracy of monitoring and avoids misalignment.

[0020] On the basis of the old equipment, save the cost, do not make big changes to the existing equipment, reduce the cost of transformation, at the same time, the effect after transformation, reduce the labor intensity of employees, improve the production efficiency, at the same time, also realize independent monitoring, single blockage and single dredging. The overall equipment has regular vibration, which helps to improve the feeding speed and avoid the situation that the feeding speed is significantly slowed down although there is feeding. Vibration plays a dredging role and speeds up the feeding speed.
