Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of yellow phosphorus electric furnace, concretely is novel phosphorus furnace blanking control device. BACKGROUND

[0002] Yellow phosphorus is an important inorganic chemical raw material, mainly used for producing phosphoric acid, phosphate fertilizer and various phosphorus compounds. It has a yellow-green solid form, easy to oxidize and burn in the air, with high activity. Yellow phosphorus is widely used in industry and agriculture, but due to its toxicity and flammability, the handling and production process needs to be strictly controlled. The traditional yellow phosphorus production method mainly adopts the way of high-temperature roasting phosphate rock and reducing agent, and the electric furnace method is a more advanced and safe technical path for producing yellow phosphorus.

[0003] The patent with publication number CN117588947A discloses an electric furnace for yellow phosphorus production by electric furnace method, which comprises a furnace body, a positioning mechanism, a stirring mechanism, a discharge control mechanism and a slag extraction mechanism. The outer surface of the furnace body is fixedly installed with a limiting ring. The top of the furnace body is placed with a furnace cover, the outer wall of the furnace cover is in close contact with the inner wall of the limiting ring. The bottom of the furnace body is fixedly installed with a discharge cover. The slag extraction mechanism is arranged on the furnace cover and comprises a boom, a circular frame, a filter screen, a control rod and a slot. The electric furnace for yellow phosphorus production by electric furnace method can directly discharge liquid phosphorus from the bottom when the electric furnace needs to discharge, and separate and store the slag on the filter screen in the furnace body. After the temperature in the furnace body is lowered, the slag can be directly collected and treated, improving the practicability of the electric furnace.

[0004] Although the above-mentioned prior art can manage the discharge process of the electric furnace to some extent by the cooperation of the discharge cover and the discharge control mechanism, control the speed of liquid phosphorus discharge, and adjust the discharge speed according to the production needs, there is a problem of poor sealing in actual application. Specifically, in the existing design, two groups of blocking plates are used to close two groups of discharge ports, and the blocking plates and the discharge cover are only in close contact, with gaps that are not effectively filled. At the same time, the blocking plates and the threaded sleeve are connected by a connecting rod, which makes the blocking plates bear the weight of all liquid phosphorus and slag in the electric furnace during use. With the extension of use time, the connecting rod is prone to bending, further reducing the sealing performance and possibly causing safety hazards. In view of this, we propose a novel phosphorus furnace blanking control device. UTILITY MODEL CONTENTS
