Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a phosphogypsum feeding device for cement production. Background Art

[0002] There are two main types of phosphogypsum: gray-black and gray-white. The particle diameter is generally 5 to 50 μm, and the crystal water content is 20% to 25%. Phosphogypsum is a solid waste generated in the wet phosphoric acid process, and its main component is calcium sulfate dihydrate. The composition of phosphogypsum is relatively complex. In addition to calcium sulfate, there are also incompletely decomposed phosphate rock, residual phosphoric acid, fluoride, acid insoluble matter, organic matter, etc.

[0003] During cement production and processing, phosphogypsum can be added for mixed production. Since phosphogypsum is mostly stored in a pile, it is easily affected by the environment and becomes damp. Therefore, it needs to be dried during processing to prevent moisture from affecting subsequent processing. Utility Model Content

[0004] The purpose of the utility model is to provide a phosphogypsum feeding device for cement production to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a cement production phosphogypsum feeding device, comprising a shell, a frame and a tank body,

[0006] The rear end surface of the frame is provided with a second driving motor, and the output shaft of the second driving motor is provided with a driving shaft;

[0007] A driven shaft is sleeved in the frame, and conveyor belts are arranged on the driven shaft and the driving shaft;

[0008] The side end surface of the shell is equipped with a tank body, and the inner wall of the shell is fitted with a ceramic heating tube;

[0009] A driving motor 1 is installed on the top surface of the tank body, and a stirring rod is arranged on the output shaft of the driving motor 1 via a rotating shaft.

[0010] Preferably, rollers are sleeved in the frame, and the rollers limit the position of the conveyor belt. The conveyor belt is limited by the rollers, so that when the phosphogypsum is transported and fed on the conveyor belt, the phosphogypsum can be supported on the conveyor belt by the rollers.

[0011] Preferably, a support frame is welded to the bottom end surface of the frame, and a bearing base is welded to the bottom end surface of the support frame. The frame can be installed and fixed by the support frame and the bearing base.

[0012] Preferably, a feed pipe is embedded and fixed on the top surface of the tank body, and the feed pipe is connected to the tank body. The phosphogypsum required for feeding can be injected into the tank body through the feed pipe.

[0013] Preferably, a discharge pipe is embedded and fixed on the bottom end surface of the tank body, and a valve is installed on the discharge pipe through a flange. The discharge pipe is embedded and fixed on the bottom end surface of the tank body, so that after the phosphogypsum enters the tank body, the personnel can turn on the driving motor to drive the stirring rod through the rotating shaft to break the phosphogypsum that needs to be fed, and after breaking, the valve on the discharge pipe can be opened for discharge.

[0014] Preferably, a mounting block is welded to the bottom end surface of the shell, and the bottom end surface of the mounting block is welded to the frame. The shell can be mounted on the frame through the mounting block.

[0015] Preferably, an air intake pipe is embedded and fixed on the shell, and a fan is installed in the air intake pipe. The air intake into the shell can be performed by turning on the fan in the air intake pipe.

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The utility model sets a tank body. When personnel feed phosphogypsum to cement production, they can inject the phosphogypsum required for feeding into the tank body through a feed pipe. After the injection, a discharge pipe is embedded and fixed through the bottom end surface of the tank body. After the phosphogypsum enters the tank body, the personnel can turn on the driving motor to drive the stirring rod through the rotating shaft to break the phosphogypsum required for feeding. After breaking, the valve on the discharge pipe can be opened to discharge, so that the phosphogypsum required for processing can be broken, and the phosphogypsum can be prevented from being damp and agglomerated, which affects the later feeding and mixing.

[0018] 2. The utility model sets a frame, when personnel feed phosphogypsum into cement production, the phosphogypsum is processed through the tank body and then discharged onto the conveyor belt. After being discharged onto the conveyor belt, personnel can turn on the second driving motor to drive the active shaft to rotate, and the rotation of the active shaft can drive the conveyor belt to rotate, thereby conveying and feeding the phosphogypsum. When feeding, the phosphogypsum material enters the outer shell and can be heated and dried by turning on the ceramic heating tube, and the fan in the air inlet pipe can be turned on to intake air into the outer shell, so that the gas in the outer shell can circulate and dry the phosphogypsum, thereby meeting the feeding of the phosphogypsum and avoiding the influence of moisture on the later processing.
