, the wall is a solid wall or a hollow wall, and is arranged on the wall.

, the roof is formed by splicing a plurality of transparent materials.

, the roof is made of transparent plastic tile or transparent glass fiber reinforced plastic tile.

Advantageous effects

The method has the beneficial effects that the separation of the waste liquid in the raw material phosphogypsum can be promoted, the water content of the phosphogypsum is reduced, and the waste liquid can be recycled.

Drawings

FIG. 1 is a schematic structural view of the present invention

1. The building comprises a wall, a roof, a conveyer belt, a waste liquid tank, a liquid discharge channel, a liquid accumulation tank, a filtering layer and a ground, wherein the wall comprises 2 parts of a roof, 3 parts of a conveyer belt, 4 parts of a waste liquid tank, 5 parts of a liquid discharge channel, 6 parts of a liquid accumulation tank, 7 parts of a filtering layer and 8 parts of.

Detailed Description

In order to explain the technical scheme of the invention in the step , the specific implementation mode of the invention is described by combining the accompanying drawings, as shown in fig. 1, in the embodiment, a side wall in a Chinese invention patent (application number: 2019102488686) applied earlier is selected as a wall 1 in the embodiment, a ceiling is selected as a roof 2 in the embodiment, a belt conveyor belt with a material baffle plate commonly used in the industry is selected as a conveyor belt 3, a factory cement floor commonly used in the industry is selected as a ground 8, a 300 mm wide groove and a 300 mm deep groove are formed in the ground 8, the length of the groove is half of a sunlight shed width according to the width of the sunlight shed, a plurality of grooves are arranged in parallel at intervals of 400 mm and are respectively arranged on two sides of a liquid drainage channel 5, in the embodiment, a groove with a width of 600 mm and a depth of 500 mm is formed in the middle of the two liquid drainage channels 6, the groove with a length penetrating through the sunlight shed is used as the liquid drainage channel 5, the end of the liquid drainage channel 5 is closed, an opening at the end of the other end is communicated with the waste liquid pool 4, a filter cloth is selected as a filter cloth which is used for digging a liquid drainage groove with the waste tank 8, a filter cloth with a liquid drainage groove, the filter cloth which is used in the liquid drainage groove, the liquid drainage groove is used for being laid on the waste tank, the liquid drainage channel 5, the liquid drainage groove, the drainage groove is used for being laid on the drainage groove, the drainage groove is used for drainage is used for being convenient for being laid, the drainage of the drainage tank, the drainage is used for being.

When the phosphogypsum recycling device is used, phosphogypsum raw materials enter a conveying belt 3 from a storage place through a conveying device, the conveying belt 3 conveys the phosphogypsum into a sunlight shed, the position of a baffle plate is adjusted in a sectional mode according to the conveying condition, the phosphogypsum is thrown to the two sides of the conveying belt 3 from the air of the sunlight shed, the temperature in the sunlight shed is high due to the action of sunlight, part of moisture is volatilized when the phosphogypsum is thrown, the phosphogypsum is emitted into the air through an air-permeable device on the roof of the sunlight shed, when the phosphogypsum accumulated at the front end of the conveying belt 3 reaches fixed height, the position of the baffle plate on the conveying belt 3 is adjusted, the thrown position moves forwards until the phosphogypsum is paved with the whole sunlight shed, at the moment, liquid contained in the phosphogypsum accumulated on the ground 8 and positioned on a filter layer 7 is separated out through a filter layer 7 and flows into a liquid accumulating tank 6 and a liquid drainage channel 5, the liquid accumulating tank 6 is communicated with the drainage channel 5, the bottom surface of the drainage channel 6 is lower than the bottom surface of the liquid accumulation channel 6, the waste liquid is automatically flowed into a waste liquid channel 5, the waste tank , the waste liquid is extracted, the waste liquid is recovered, and the waste liquid is recovered, and the waste is recovered at the same time, the cost is reduced due to the.
