Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0066] The utility model provides a building material regeneration and impurity removal device through improvement. The technical solution of the utility model is:

[0067] like Figures 1-10 As shown, a building material recycling and impurity removal device includes:

[0068] A bracket 1 is provided on which a first water washing tank 2, a flotation tank 3 and a second water washing tank 4 are fixed. The first water washing tank 2, the flotation tank 3 and the second water washing tank 4 are arranged vertically. A second solenoid valve 17 is provided through the bottom of the first water washing tank 2.

[0069] A material delivery pipe 18, one end of which is connected to the second solenoid valve 17, and the other end of which passes through the inner wall of the flotation tank 3;

[0070] The fixing frame 13 is fixed on the first water washing tank 2. The bottom of the fixing frame 13 is rotatably provided with a rotating shaft 15, and the rotating shaft 15 passes through the bottom of the first water washing tank 2;

[0071] The connecting seat 25 is slidably mounted on the rotating shaft 15 and is located between the first water washing tank 2 and the flotation tank 3;

[0072] Multiple adsorption components, each of which is fixed to the connecting seat 25, and is used to adsorb foam;

[0073] The seat body 23 is fixed on the inner wall of the bottom of the flotation tank 3, and the rotating shaft 15 is rotatably arranged on the top of the seat body 23;

[0074] Multiple circular holes 24 are equidistantly provided on the top of the base 23. The multiple circular holes 24 are interconnected with the interior of the base 23. The inner wall of the base 23 is provided with multiple adjustment components, and the multiple adjustment components correspond to the multiple circular holes 24 one by one.

[0075] The adjustment component includes station one and station two. When the adjustment component is in station one, the adjustment component is below the circular hole 24 to partially seal the circular hole 24. When the adjustment component is in station two, the adjustment component is away from the circular hole 24.

[0076] Two stirring assemblies, both of which are fixed to the rotating shaft 15, and the two stirring assemblies are respectively located in the first water washing tank 2 and the flotation tank 3;

[0077] The water washing component is arranged in the second water washing tank 4, and the water washing component is connected to the adsorption component;

[0078] A negative pressure component is provided on one side of the bracket 1;

[0079] The control component is connected to the negative pressure component, the control component is connected to the water washing component and the seat body 23, and the control component is used to control the connection state of the water washing component and the seat body 23.

[0080] After the phosphogypsum material is crushed and processed, it becomes a powder material. The powder material and water are transported to the first water washing tank 2, and the first water washing treatment is carried out in the first water washing tank 2. The stirring component in the first water washing tank 2 works together to make the powder material uniformly dispersed in the water;

[0081] After being processed, the material in the first water washing tank 2 enters the flotation tank 3, where it undergoes flotation treatment. The flotation agent is selected to combine the phosphogypsum in the powdered material with the foam, allowing the phosphogypsum to float on the liquid surface in the flotation tank 3. At this point, the foam can be adsorbed by the adsorption component into the second water washing tank 4, achieving separation of the phosphogypsum from other impurities in the material.

[0082] During the flotation process, the control component allows the gas generated by the negative pressure component to enter the seat 23 when it is working, thereby generating fine bubbles in the flotation tank 3, thereby increasing the flotation effect. After flotation, the control component uses the negative pressure generated by the negative pressure component to extract the waste residue and wastewater in the flotation tank 3, thereby achieving rapid discharge of the wastewater slag in the flotation tank 3.

[0083] Furthermore, the adsorption component includes:

[0084] The adsorption seat 21 is fixed to the side wall of the connecting seat 25, and a plurality of adsorption holes are opened at the bottom of the adsorption seat 21;

[0085] The first hose 19 is provided through the top of the adsorption seat 21 .

[0086] Furthermore, it also includes:

[0087] A first motor 14 is fixed to the top of the fixing frame 13, and an output shaft of the first motor 14 is fixed to the rotating shaft 15;

[0088] The negative pressure pipe 27 is fixedly disposed in the rotating shaft 15 and passes through the bottom outer wall of the flotation tank 3. The plurality of first hoses 19 are all connected to the negative pressure pipe 27.

[0092] The annular guide rail 20 is fixed to the telescopic ends of the plurality of first electric push rods 22 , and each adsorption seat 21 is slidably connected to the annular guide rail 20 .

[0093] When the switch of the first electric push rod 22 is turned on, the first electric push rod 22 starts working, causing the annular guide rail 20 to descend, cooperating with the sliding between the connecting seat 25 and the rotating shaft 15 to descend the adsorption seat 21. When the adsorption seat 21 descends to the level of the liquid in the flotation tank 3, the low-pressure area at the adsorption hole is used to adsorb the foam on the surface of the liquid in the flotation tank 3.

[0094] Furthermore, the water washing component includes:

[0095] The cover 40 is hinged to the top of the second washing tank 4, and the bottom end of the second hose 28 passes through the bottom of the cover 40;

[0096] A third hose 37 is provided through the top of the cover 40;

[0097] The water supply pipe 38 is fixed to the side wall of the second washing tank 4;

[0098] A second stirring rod 34 is rotatably mounted on the inner wall of the bottom of the second washing tank 4. A second motor 35 is mounted on the bottom of the second washing tank 4, and an output shaft of the second motor 35 is fixed to the second stirring rod 34.

[0099] The discharge valve 33 is provided on the outer wall of the bottom of the second washing tank 4 .

[0100] When the second washing tank 4 is in a low-pressure state, the second hose 28 causes the inside of the cover 29 to be in a low-pressure state, and then the negative pressure pipe 27 and the first hose 19 cause a low-pressure area to be generated at the adsorption holes on the adsorption seat 21.

[0101] Furthermore, the negative pressure component includes:

[0102] The gas-liquid separation tank 5 is arranged on one side of the bracket 1, and a waste valve 6 is provided through the bottom of the outer wall of the gas-liquid separation tank 5;

[0103] Box body 7, box body 7 is fixed on the side wall of gas-liquid separation tank 5, and an air compressor is provided in box body 7;

[0104] An inlet pipe 9, one end of which is connected to the inlet port of the air compressor, and the other end of which is arranged through the top of the gas-liquid separation tank 5;

[0105] The gas tank 10 is fixed to the gas-liquid separation tank 5, and a first solenoid valve 11 and a pressure relief valve 12 are provided through the top of the gas tank 10;

[0106] An air supply pipe 39 , one end of which is connected to the first solenoid valve 11 , and the other end of which is connected to the pipe body 26 ;

[0107] The output pipe 8 has one end connected to the output port of the air compressor, and the other end connected to the air tank 10.

[0108] Furthermore, the control component includes:

[0109] The three-way valve 36 is fixed on the side wall of the gas-liquid separation tank 5 , and the pipe body 26 and the third hose 37 are both connected to the three-way valve 36 .

[0110] Furthermore, the adjustment component includes:

[0111] A sealing plate 32, with a plurality of small holes extending through the top of the sealing plate 32;

[0112] Two connecting rods 30, both of which are fixed to the inner wall of the base body 23, and the sealing plate 32 is slidably connected to the two connecting rods 30;

[0113] A second electric push rod 31 is fixed to the inner wall of the base 23, and the telescopic end of the second electric push rod 31 is fixed to the sealing plate 32;

[0114] The tube body 26, the tube body 26, one end of the tube body 26 is communicated with the seat body 23, and the other end of the tube body 26 is connected to the negative pressure component.

[0115] The state of the three-way valve 36 is controlled so that the third hose 37 can be connected to the gas-liquid separation tank 5 through the three-way valve 36, and the pipe body 26 and the gas-liquid separation tank 5 are sealed by the three-way valve 36. At the same time, the first solenoid valve 11 is opened. When the air compressor is working, the gas in the gas-liquid separation tank 5 is extracted through the input pipe 9, making the interior of the gas-liquid separation tank 5 in a low-pressure state. The low pressure in the gas-liquid separation tank 5 can pass through the third hose 37 to make the second water washing tank 4 in a low-pressure state. The gas in the gas tank 10 enters the pipe body 26 through the first solenoid valve 11 and the air supply pipe 39. Since the pipe body 26 and the gas-liquid separation tank 5 are in a sealed state at this time, the gas enters the pipe body 26 and then enters the base body 23. The switch of the second electric push rod 31 is turned on, so that the sealing plate 32 moves along the connecting rod 30 to the bottom of the circular hole 24, so that the gas in the base body 23 can only be discharged through the small holes on the sealing plate 32, so that fine bubbles are generated in the flotation tank 3, thereby improving the flotation effect.

[0116] The three-way valve 36 is controlled to operate so that the tube body 26 and the gas-liquid separation tank 5 are connected through the three-way valve 36. The sealing plate 32 is driven away from the circular hole 24 by the second electric push rod 31. The negative pressure in the gas-liquid separation tank 5 is caused to be in a negative pressure state in the seat body 23 through the three-way valve 36 and the tube body 26. At this time, the bottom slurry in the flotation tank 3 enters the seat body 23 through the circular hole 24 under the action of negative pressure, and then enters the gas-liquid separation tank 5 through the tube body 26 and the three-way valve 36. Under the action of gravity, the bottom slurry is stored at the bottom of the gas-liquid separation tank 5.

[0117] Furthermore, the stirring assembly includes:

[0118] A plurality of first stirring rods 16 are fixed on the rotating shaft 15 at equal distances.

[0119] The specific working principle is: the phosphogypsum material after preliminary treatment is transported to the first water washing tank 2, water is then added to the first water washing tank 2, and finally the sealing between the cover 40 and the second water washing tank 4 is ensured;

[0120] The first motor 14 is turned on. When the first motor 14 is working, it drives the rotating shaft 15 to rotate, thereby driving the first stirring rod 16 to rotate, so that the phosphogypsum is fully mixed with water in the first washing tank 2 to perform preliminary washing.

[0121] After washing, the second solenoid valve 17 is turned on, and the washed powdered material in the first washing tank 2 and the water are passed through the feed pipe 18 into the flotation tank 3. At this time, a flotation agent is added to the flotation tank 3. During the rotation of the first stirring rod 16 in the flotation tank 3, the powdered material is fully mixed with the water and the flotation agent. The phosphogypsum in the powdered material is combined with the foam under the action of the flotation agent and floats upward.

[0122] Turn on the switch of the air compressor and control the state of the three-way valve 36 so that the third hose 37 can be connected to the gas-liquid separation tank 5 through the three-way valve 36, and the tube body 26 and the gas-liquid separation tank 5 are sealed by the three-way valve 36. At the same time, open the first solenoid valve 11. When the air compressor is working, the gas in the gas-liquid separation tank 5 is extracted through the input pipe 9, making the interior of the gas-liquid separation tank 5 in a low-pressure state. The low pressure in the gas-liquid separation tank 5 can be passed through the third hose 37 to make the second water washing tank 4 in a low-pressure state. After the second water washing tank 4 is in a low-pressure state, the cover body 29 is in a low-pressure state through the second hose 28, and then the negative pressure pipe 27 and the first hose 19 are used to make the gas in the gas-liquid separation tank 5 in a low-pressure state. A low-pressure area is generated at the adsorption hole on the adsorption seat 21, and then the switch of the first electric push rod 22 is turned on. When the first electric push rod 22 works, the annular guide rail 20 is lowered, and the sliding between the connecting seat 25 and the rotating shaft 15 is coordinated to lower the adsorption seat 21. When the adsorption seat 21 is lowered to the level of the liquid in the flotation tank 3, the low-pressure area at the adsorption hole is used to adsorb the foam on the surface of the liquid in the flotation tank 3. The adsorbed foam enters the second water washing tank 4 through the adsorption seat 21, the first hose 19, the negative pressure pipe 27, the cover 29, and the second hose 28, thereby allowing the phosphogypsum to enter the second water washing tank 4 along with the foam, thereby realizing the collection of the phosphogypsum after flotation;

[0123] When the air compressor is working, the gas output by the air compressor enters the gas tank 10 through the output pipe 8, making the inside of the gas tank 10 in a high-pressure state. When the gas pressure in the gas tank 10 reaches a certain level, the gas inside the gas tank 10 is discharged through the pressure relief valve 12, so that the gas pressure in the gas tank 10 is always maintained within a certain range.

[0124] During the flotation process, the gas in the gas tank 10 enters the tube body 26 through the first solenoid valve 11 and the gas supply pipe 39. Since the tube body 26 and the gas-liquid separation tank 5 are in a sealed state at this time, the gas enters the tube body 26 and then enters the interior of the seat body 23.

[0125] During the flotation stage, the second electric push rod 31 is turned on, so that the sealing plate 32 moves along the connecting rod 30 to the position below the circular hole 24, so that the gas in the seat 23 can only be discharged through the small holes on the sealing plate 32, so that fine bubbles are generated in the flotation tank 3, thereby improving the flotation effect;

[0126] After flotation, water is injected into the second washing tank 4 via the water supply pipe 38, and the second motor 35 is turned on. When the second motor 35 is working, it drives the second stirring rod 34 to rotate, thereby washing the phosphogypsum in the foam. After washing is completed, the discharge valve 33 is opened, and the material in the second washing tank 4 is discharged through the discharge valve 33 for subsequent dehydration, drying and other treatments to complete the entire phosphogypsum regeneration process.

[0127] After the flotation is completed, the remaining bottom slurry in the flotation tank 3 needs to be processed. The three-way valve 36 is controlled to work so that the pipe body 26 and the gas-liquid separation tank 5 are connected through the three-way valve 36, and the third hose 37 and the gas-liquid separation tank 5 are sealed by the three-way valve 36. At the same time, the switch of the first solenoid valve 11 is closed. Finally, the second electric push rod 31 drives the sealing plate 32 away from the circular hole 24. After completing the above operations, the negative pressure in the gas-liquid separation tank 5 is caused to be in a negative pressure state through the three-way valve 36 and the pipe body 26. At this time, the bottom slurry in the flotation tank 3 enters the seat body 23 through the circular hole 24 under the action of negative pressure, and then enters the gas-liquid separation tank 5 through the pipe body 26 and the three-way valve 36. Under the action of gravity, the bottom slurry is stored at the bottom of the gas-liquid separation tank 5. When the waste water and waste residue in the bottom slurry are processed, the waste valve 6 is opened to discharge the waste water and waste residue in the gas-liquid separation tank 5.
