AI Technical Summary
The powdered phosphogypsum in the silo is prone to blockage due to the high moisture content in the slip pipe. The existing vibrator unblocking method is very noisy, affecting the staff.
A slip pipe system including a cutting inclined pipe and a straight pipe is designed, with scraping anti-blocking components inside. By driving the motor to drive the scraping rod to rotate, phosphogypsum is prevented from condensing and blocking in the inclined pipe and straight pipe, and instead of vibrator to unblock.
Effectively prevent phosphogypsum blockage, reduce noise pollution, improve the smoothness of cutting, reduce equipment wear, and extend equipment life.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of phosphogypsum discharge, and in particular to a phosphogypsum anti-blocking discharge chute. Background Art
[0002] Phosphogypsum is a solid waste generated during the phosphoric acid production process. It primarily originates from the process of producing phosphoric acid by reacting phosphate rock with sulfuric acid. Phosphogypsum typically contains impurities such as incompletely reacted phosphate rock, phosphoric acid, fluoride, organic matter, and some heavy metals. Large accumulations of phosphogypsum not only consume land resources but also pose a risk of environmental pollution to the soil, water, and air. However, through technical treatment and process improvements, phosphogypsum can be used in a variety of ways, such as in the production of building materials (such as gypsum board and gypsum blocks), soil improvement, and cement retarders, thereby achieving efficient resource utilization and environmental protection.
[0003] The powdered phosphogypsum in the silo is discharged to the mixer or auger through a chute. When the moisture content of the phosphogypsum in the silo is high, the powdered phosphogypsum is prone to arching and clogging in the chute, resulting in poor discharge. The existing solution is to install a vibrator on the chute to break the arch and remove the blockage. However, when the vibrator is working, it will knock on the chute at a high frequency. The knocking sound is amplified by the chute and is very noisy. Summary of the Invention
[0004] The purpose of the embodiments of the present application is to provide a phosphogypsum anti-blocking discharge chute, which can solve the technical problems raised by the background technology.

[0006] Furthermore, the first scraper anti-blocking assembly includes a first rotating shaft, a first connecting plate and a first scraper rod. The first rotating shaft is rotatably set in the discharge inclined tube. One end of the first rotating shaft passes through the first end sealing plate and is connected to the output shaft of the first drive motor. The first scraper rod is connected to the first rotating shaft through the first connecting plate, and the first scraper rod abuts against the inner wall of the discharge inclined tube.
