Description

Technical Field

[0001] The invention relates to the technical field of phosphogypsum proportioned concrete building materials, in particular to a cyclone conveying device for phosphogypsum proportioned concrete building materials. Background Art

[0002] Phosphogypsum concrete building materials refer to a new type of building material that uses phosphogypsum as the main raw material and combines it with concrete in a specific ratio. This building material can not only effectively utilize industrial waste phosphogypsum and reduce environmental pollution, but also maintain the basic properties of concrete and even improve them in some aspects.

[0003] According to the patent document: CN216945273U, a cyclone conveying device for mixing concrete building materials with phosphogypsum is disclosed, which includes a machine base, a phosphogypsum tank and a cyclone adsorption shaft. The phosphogypsum tank is fixed and supported by a support plate of the machine base. The hollow shaft body of the cyclone adsorption shaft axially passes through the two ends of the phosphogypsum tank and cooperates with it. The cyclone flap on the hollow shaft body is located inside the phosphogypsum tank. The negative pressure horn is connected to the hollow shaft body, and the exhaust fan is connected to one end of the hollow shaft body. The filtered phosphogypsum enters the phosphogypsum tank from the hopper, and the hollow shaft body drives the cyclone flap to rotate and disturb the phosphogypsum powder. The dry phosphogypsum powder enters the hollow shaft body from the negative pressure horn and is discharged into the mixing furnace through the exhaust fan, so as to avoid agglomerated particles from entering the mixing furnace, which is beneficial to improve the balance of the mixture of phosphogypsum powder and cement.

[0004] Concrete using phosphogypsum as a mix material not only changes the properties of concrete, but also effectively utilizes phosphogypsum, which is an environmentally friendly material. Its preparation process is different from that of traditional concrete, including mixing the screened phosphogypsum with cement, and then adding aggregate and water for stirring. At present, phosphogypsum is directly sent to the mixing furnace to be mixed with cement through a cyclone conveyor. However, phosphogypsum is usually in powder form. During a long period of storage, it is very easy to solidify due to the moisture on the ground. It is usually dried before mixing. However, during the drying process, the phosphogypsum solidified due to moisture is easy to stick together to form hard gypsum balls, which may clog the pipeline of the conveying device during transportation through a cyclone conveyor. In addition, the phosphogypsum solidified into gypsum balls is not easy to blend with concrete, which may cause the uniformity of the concrete to decrease, affecting the quality of the final product. Summary of the invention

[0035] When it is necessary to transport the phosphogypsum, the staff pours the phosphogypsum into the inner wall of the lower silo shell 31 through the lower silo discharge funnel 315, so that it falls to the top of the screen plate 341. At this time, the double-axis motor 3453 on the inner wall of the shaking mechanism 345 is started, so that the two turntables 3454 rotate synchronously, and then the rotating rod 3455 is pushed to drive the elliptical push-pull block 3456 to reciprocate on the left and right sides of the bottom front side of the screen plate 341. This reciprocating motion causes the screen plate 341 to shake, thereby preliminarily screening the phosphogypsum, and the uncondensed phosphogypsum falls into the discharge pipe 313 through the screen 342 for discharge.

[0036] See also Figure 7-10 The closing control mechanism 4 includes a control frame 41, a closing plate 42 is fixedly connected to the rear side of the control frame 41, and the control frame 41 includes a rectangular frame 411. The four sides of the rear side of the rectangular frame 411 are respectively fixedly connected with connecting rods 412. The rear sides of the four connecting rods 412 are fixedly connected to the four sides of the front side of the feeding tube 313. The inner sides of the upper and lower groups of connecting rods 412 are fixedly connected to two sliding rods 416. The top and bottom of the left and right sides of the inner wall of the rectangular frame 411 are rotatably connected with V-shaped rotating rods 414. The inner sides of the front sides of the upper and lower groups of V-shaped rotating rods 414 are rotatably connected with hydraulic push rods 413. The inner walls of the rear sides of the upper and lower groups of V-shaped rotating rods 414 are rotatably connected with push blocks 41 5. The closing plate 42 includes two L-shaped connecting plates 421, the top and bottom of the two L-shaped connecting plates 421 are fixedly connected with two connecting plate sliders 422, the outer middle parts of the two L-shaped connecting plates 421 are respectively rotatably connected to the inner sides of the left and right groups of push blocks 415, the inner walls of the four groups of connecting plate sliders 422 are respectively slidably connected to the left and right sides of the outer walls of the two groups of slide bars 416, the outer sides of the rear sides of the two L-shaped connecting plates 421 are fixedly connected with push-pull plates 423, the inner sides of the two push-pull plates 423 are fixedly connected with closing blocks 424, and the outer walls of the two closing blocks 424 are respectively slidably connected to the inner walls of the two feeding tube side grooves 314 opened by the feeding tube 313;

[0037] When the phosphogypsum is transported to the concrete mixing container through the material pipe 5, the fan 6, the material pipe 7, the air duct 8, the air duct rack 9, the second air duct 10 and the discharge pipe 11, in order to prevent the material feeding mechanism 3 from continuing to feed during the mixing process, thereby causing the ratio of concrete and phosphogypsum to be unbalanced, thereby affecting the quality of the processed building materials, the closing control mechanism 4 is started, and the V-shaped rotating rod 414 is pushed to rotate through the telescopic action of the hydraulic push rod 413, thereby driving the push block 415 to push the closing plates 42 on both sides to move inward, so as to realize the opening and closing of the closing plates 42. When it is necessary to close the material feeding pipe 313, the hydraulic push rod 413 is used to push the V-shaped rotating rod 414 to rotate, thereby driving the push block 415 to push the closing plates 42 on both sides to move inward, so as to realize the opening and closing of the closing plates 42. The rod 413 is extended and the push block 415 moves inward, so that the connecting plate slider 422 on the L-shaped connecting plate 421 slides inward along the slide rod 416, and finally the closing plate 42 is closed, thereby preventing the phosphogypsum from continuing to fall. Conversely, when it is necessary to open the discharge pipe 313, the hydraulic push rod 413 contracts, the push block 415 moves outward, the connecting plate slider 422 slides outward along the slide rod 416, and the closing plate 42 opens accordingly, allowing the phosphogypsum to continue to fall. In this way, it can be ensured that when the phosphogypsum is mixed with concrete, the material will not continue to be discharged due to errors of equipment or staff, thereby causing the mix ratio to be out of balance.

[0038] Working principle: When it is necessary to transport phosphogypsum, the staff pours the phosphogypsum into the inner wall of the lower silo shell 31 through the lower silo discharge funnel 315, so that it falls to the top of the screening plate 341. At this time, the double-axis motor 3453 on the inner wall of the shaking mechanism 345 is started, so that the two turntables 3454 rotate synchronously, and then the rotating rod 3455 is pushed to drive the elliptical push-pull block 3456 to reciprocate on the left and right sides of the bottom front side of the screening plate 341. This reciprocating motion causes the screening plate 341 to shake, thereby preliminarily screening the phosphogypsum. The unsolidified phosphogypsum falls into the discharge pipe 313 through the screen 342 and is discharged. At the same time, the motor 35 is started, and the operation of the motor 35 drives the transmission plate 36 and the crawler 37. The movement of the crawler 37 is transmitted to the extrusion roller rotating rod 39 through the second transmission plate 38, so that the extrusion roller 310 rotates, and the phosphogypsum solidified into blocks slides to the top of the extrusion plate 311 through the screen plate 341. The extrusion roller 310 rotates to squeeze the falling phosphogypsum so that the phosphogypsum solidified into blocks is re-extruded into powder, and slides through the extrusion plate 311 to the discharge pipe 313 for discharge;

[0039] Start the closing control mechanism 4, and through the telescopic action of the hydraulic push rod 413, the V-shaped rotating rod 414 is pushed to rotate, thereby driving the push block 415 to push the closing plates 42 on both sides to move inward, so as to realize the opening and closing of the closing plates 42. When it is necessary to close the discharge pipe 313, the hydraulic push rod 413 is extended, and the push block 415 is moved inward, so that the connecting plate slider 422 on the L-shaped connecting plate 421 slides inward along the slide rod 416, and finally the closing plate 42 is closed, thereby preventing the phosphogypsum from continuing to fall. Conversely, when it is necessary to open the discharge pipe 313, the hydraulic push rod 413 is contracted, the push block 415 is moved outward, and the connecting plate slider 422 slides outward along the slide rod 416, and the closing plate 42 is opened accordingly, allowing the phosphogypsum to continue to fall. In this way, it can be ensured that when the phosphogypsum is mixed with concrete, the material will not continue to be discharged due to the mistakes of the equipment or the staff, thereby causing the mixing ratio to be unbalanced.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
