Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of phosphogypsum processing, in particular to a phosphogypsum concrete preparation device and method. BACKGROUND

[0002] Phosphogypsum is an industrial by-product of wet-process phosphoric acid production in phosphorus chemical enterprises, and the main component of phosphogypsum is calcium sulfate dihydrate, which is powdery and generally appears in colors such as grayish white, grayish yellow and light green. It also contains organic phosphorus, sulfur and fluorine compounds, which pollute the environment to a great extent. Therefore, it is very urgent to process and utilize phosphogypsum.

[0003] Using phosphogypsum to make concrete can effectively utilize phosphogypsum resources. The processing technology is roughly as follows: phosphogypsum, cement and the like are mixed. When preparing concrete by mixing phosphogypsum, cement and the like, the raw materials are usually put into a concrete mixer. At present, the raw materials are mostly put into the concrete mixer by manually scooping them up with a shovel tool. However, this method has the following defects: the feed inlet of the traditional concrete mixer is relatively high, so the raw materials need to be lifted to the upper part of the concrete mixer for feeding by manual labor, which is labor-intensive. On the other hand, the weight of each raw material cannot be controlled by manual labor, and too much or too little of some raw materials will affect the quality of the prepared phosphogypsum concrete. Therefore, we propose a phosphogypsum concrete preparation device and method. SUMMARY

[0004] The purpose of the present application is to provide a phosphogypsum concrete preparation device and method to solve the problems raised in the background.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0006] A phosphogypsum concrete preparation device comprises a mixer, a connecting frame assembly, a guide frame assembly, a material containing assembly and a driving assembly.

[0007] The connecting frame assembly is arranged on the outer wall of the mixer. The guide frame assembly comprises a guide part and a weighing part. The guide part is arranged on the connecting frame assembly, and the weighing part is arranged on the guide part. The material containing assembly comprises a material containing part and a connecting sliding mechanism. The material containing part is arranged on the guide part through the connecting sliding mechanism. The material containing part is used for loading raw materials. The driving assembly is arranged on the connecting frame assembly.

[0008] When the weighing part detects that the raw materials in the material containing part reach a preset threshold, the driving assembly is controlled to drive the material containing part to move upward along the guide part. After the material containing part moves to a specified position at the upper end of the guide part, the connecting sliding mechanism cooperates with the guide part to drive the material containing part to overturn, so that the raw materials in the material containing part are unloaded into the mixer.

[0009] A further improvement is that the connecting frame assembly includes:

[0010] Two sets of limiting rings are provided, which are respectively fixedly sleeved on the upper and lower ends of the outer wall of the mixer.

[0011] The movable ring is movably fitted onto the outer wall of the limiting ring.

[0012] A further improvement is that the guide portion includes:

[0013] The vertical frame is provided in two sets, both of which are symmetrically fixed vertically on one side of the movable ring. The top of the vertical frame extends to the top of the mixer. Vertical grooves are provided on opposite sides of both sets of vertical frames to restrict the vertical movement of the connecting sliding mechanism.

[0014] An annular component is located at the top of the vertical frame. The annular component has an annular groove that communicates with the vertical groove, which is used to restrict the rotational movement of the connecting sliding mechanism relative to the annular component.

[0015] A further improvement is that the weighing unit includes a base plate located at the bottom between two sets of vertical frames. The base plate is equipped with a weighing device for detecting the weight of the material holding part. The weighing device is electrically connected to an external controller, and the external controller is electrically connected to a drive assembly.

[0022] The shaft body has two sets, which are fixed to both ends of the connecting block respectively;

[0023] A limiting plate is fixedly installed at the end of the shaft and is located in a vertical groove. The upper and lower ends of the limiting plate are equipped with limiting rollers that rotate through a rotating shaft. The diameter of the limiting rollers is adapted to the width of the vertical groove, and the distance between the opposite ends of the two sets of limiting rollers is adapted to the diameter of the annular groove.

[0024] The elastic telescopic rod has one end connected to the center of the limiting plate away from the shaft, and the other end is embedded with a ball bearing that contacts the bottom of the vertical groove.

[0025] The bottom center of the annular groove is provided with a ball groove. When the ball corresponds to the ball groove, the elastic telescopic rod drives the ball into the ball groove.

[0026] A further improvement is that the annular groove is provided with an elastic reset element and a detection element;

[0027] The elastic reset component includes two sets of sliding blocks. Both sets of sliding blocks are slidably disposed in the annular groove through an arc-shaped groove on the inner wall of the annular groove. One set of sliding blocks is located at the upper end of the inner wall of the annular groove and is used to contact the end of the top limiting roller that rotates counterclockwise with the limiting plate. The other set of sliding blocks is located at the lower end of the inner wall of the annular groove and is used to contact the end of the top limiting roller that rotates counterclockwise with the limiting plate. The side of the sliding block away from the limiting roller is connected to the limiting block fixed to the inner wall of the annular groove through an arc-shaped elastic element.

[0028] The detection element is located on the outside of an annular component. The detection element includes a pressure sensor located at the bottom of a ball groove. The pressure sensor is electrically connected to an external controller. After receiving the pressure signal from the elastic telescopic rod, the pressure sensor sends a signal to the external controller to control the telescopic device to work.

[0029] A further improvement is that the drive assembly includes an electrical component housing located on one side of two sets of vertical frames facing the mixer. Inside the electrical component housing is a winding roller driven by a rotating device. Both ends of the outer wall of the winding roller are wound with pull ropes. One end of each of the two sets of pull ropes passes over a guide energy storage drive device located on the vertical frame and is connected to the front and rear outer ends of the top of the material container, respectively. The rotating device is electrically connected to an external controller.

[0030] The drive assembly also includes a rotating device disposed inside the electrical component housing. The output end of the rotating device is provided with a drive gear. One end of the drive gear movably penetrates through the side wall of the electrical component housing. The outer wall of the mixer is fixedly fitted with a toothed ring for meshing with the drive gear.

[0031] A further improvement is that the guiding energy storage drive device includes an L-shaped frame, of which there are two sets, respectively located on the top of two sets of annular parts. The outer wall of the transverse part of the L-shaped frame is movably fitted with a sleeve for the pull rope to pass through via a bearing. Each of the two sets of L-shaped frames is fixed with a support frame at one end opposite to the other. A driven shaft is rotatably provided transversely through the top between the two sets of support frames. The end of the driven shaft and the sleeve are connected by a gear set. A toothed gear is fitted on the outer wall of the driven shaft. A drive shaft is rotatably provided at the bottom between the two sets of support frames. A torsion spring is provided at the connection between the drive shaft and the support frame. A driven gear that meshes with the toothed gear is fitted on the outer wall of the drive shaft. A circular roller is fitted on the outer wall of the drive shaft, and the outer circumference of the circular roller is uniformly provided with protrusions for contacting the outer end of the top of the flipping material holding part. When the outer end of the top of the material holding part contacts the outer wall of a protrusion, the toothless section on the toothed gear corresponds to the driven gear.

[0032] It also includes an elastic connecting rod, one end of which is connected to the end of the pull rope away from the winding roller, and the other end is connected to the top outer end of the material holding shell.

[0033] A method for preparing phosphogypsum concrete, utilizing the aforementioned preparation apparatus, specifically includes the following steps:

[0034] S1: Prepare the raw materials needed to prepare phosphogypsum concrete. First, put one of the raw materials into the material holding part until the weighing part detects that the raw material in the material holding part has reached the preset threshold. At this time, stop putting the raw material into the material holding part. The weighing part controls the drive component to drive the material holding part to move along the guide part. After the material holding part moves to the designated position at the top of the guide part, the material holding part continues to move. With the cooperation of the guide part and the connecting sliding mechanism, the material holding part is driven to flip over, so that the raw material in the material holding part is unloaded into the mixer.

[0035] S2: After the raw materials are put into the mixer, the material holding part is reset by the drive component, and the next raw material is weighed and added until all the raw materials required for the preparation of phosphogypsum concrete are put into the mixer. The raw materials are stirred by the mixer, and the prepared phosphogypsum concrete can be discharged by opening the discharge port of the mixer.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] This invention includes a connecting frame assembly, a guide frame assembly, a material holding assembly, and a drive assembly on a mixer. Raw materials are manually loaded into the material holding section, and weighing is performed by a weighing unit in the guide frame assembly. When the weighing unit detects that the amount of raw material in the material holding section has reached a preset threshold, the drive assembly is controlled to move the material holding section along the guide section. A connecting sliding mechanism, after the material holding section moves to a designated position on the upper end of the guide section, cooperates with the guide section to drive the material holding section to flip, thus unloading the raw material into the mixer. This completes the weighing and lifting unloading of the raw materials, reducing manual labor intensity and facilitating the rational distribution of various raw materials used in the preparation of gypsum concrete. This avoids the impact of excessive or insufficient addition of some raw materials on the quality of the prepared phosphogypsum concrete. Simultaneously, the guide energy storage drive device causes the material holding section to vibrate during the flipping unloading process, improving the unloading efficiency of the material holding section.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] Please see the appendix Figure 1 - Appendix Figure 2 A phosphogypsum concrete preparation device includes a mixer 1, and also includes a connecting frame assembly, a guide frame assembly, a material holding assembly, and a drive assembly;

[0049] The connecting frame assembly is located on the outer wall of the mixer 1. The guide frame assembly includes a guide part and a weighing part. The guide part is located on the connecting frame assembly, and the weighing part is located on the guide part. The material holding assembly includes a material holding part and a connecting sliding mechanism. The material holding part is located on the guide part through the connecting sliding mechanism. The material holding part is used to load raw materials. The drive assembly is located on the connecting frame assembly.

[0050] When the weighing unit detects that the raw material in the holding section has reached the preset threshold, it controls the drive component to drive the holding section to move upward along the guide section. After the holding section moves to the designated position at the top of the guide section, the connecting sliding mechanism cooperates with the guide section to drive the holding section to flip, so that the raw material in the holding section is unloaded into the mixer 1.

[0051] Preferably, the connecting frame assembly of this embodiment includes: two sets of limiting rings 3, which are respectively fixedly sleeved on the upper and lower ends of the outer wall of the mixer 1; and a movable ring 4, which is movably sleeved on the outer wall of the limiting rings 3. The vertical cross-section of the limiting rings 3 is I-shaped, and the limiting rings 3 are used to ensure that the movable ring 4 can only rotate and will not move up and down.

[0052] Please see the appendix Figure 4 - Appendix Figure 6 Preferably, the guide portion of this embodiment includes:

[0053] The vertical frame 5 is provided in two sets, both of which are symmetrically fixed vertically on one side of the movable ring 4. The top of the vertical frame 5 extends to the top of the mixer 1. The two sets of vertical frames 5 are provided with vertical grooves 51 on opposite sides to restrict the vertical movement of the connecting sliding mechanism.

[0054] The annular component 12 is located at the top of the vertical frame 5. The annular component 12 has an annular groove 121 that communicates with the vertical groove 51, which is used to restrict the rotational movement of the connecting sliding mechanism relative to the annular component 12.

[0055] Preferably, the weighing unit in this embodiment includes a base plate 7 located at the bottom between two sets of vertical frames 5. The base plate 7 is provided with a weighing device 8 for detecting the weight of the material holding part. The weighing device 8 is a prior art device, such as a pressure sensor. The weighing device 8 is electrically connected to an external controller, and the external controller is electrically connected to a drive component. When the weighing device 8 detects that the weight of the material holding part reaches a preset threshold, the drive component is used to lift the material holding part and drive the material holding part to unload.

[0056] Preferably, the material holding section of this embodiment includes:

[0057] The material holding shell 6 has a hollow top and is located above the weighing device 8. The top of the material holding shell 6 is detachably equipped with a shell cover 25. The bottom of the material holding shell 6 facing the mixer 1 has a discharge port 26. When loading raw materials into the material holding shell 6, the shell cover 25 can be opened. After loading the raw materials, the shell cover 25 can be closed.

[0058] The sealing plate 27 is located inside the material holding shell 6 and is driven by the telescopic device 28 located on the inner wall of the material holding shell 6 to open or close the discharge port 26.

[0059] The top of the mixer 1 is provided with a guide ring 2 that matches the discharge port 26. The guide ring 2 is funnel-shaped, and the raw material flowing downward from the discharge port 26 is guided into the mixer 1 by the guide ring 2.

[0060] Preferably, the connecting sliding mechanism in this embodiment includes:

[0061] The connecting block 19 is located at the top of the side of the material container 6 facing the mixer 1, and is situated between the two sets of vertical frames 5;

[0062] The shaft 20 is provided in two sets, which are respectively fixed to both ends of the connecting block 19;

[0063] The limiting plate 21 is fixedly installed at the end of the shaft 20 and located in the vertical groove 51. The upper and lower ends of the limiting plate 21 are equipped with limiting rollers 22 that rotate through a rotating shaft. The diameter of the limiting rollers 22 is adapted to the width of the vertical groove 51. It should be noted that the diameter of the limiting rollers 22 is larger than the width of the limiting plate 21, so that the outer circumferential wall of the limiting rollers 22 contacts the inner side wall of the vertical groove 51. With this arrangement, when the material holding part moves along the vertical groove 51 driven by the drive assembly, it is limited by the limiting rollers 22 and will not rotate through the shaft 20, but can only move up and down. The distance between the opposite ends of the two sets of limiting rollers 22 is adapted to the diameter of the annular groove 121. For example, in the attached figure, the distance between the opposite ends of the two sets of limiting rollers 22 is d1, which is adapted to the diameter of the annular groove 121. That is, when the limiting plate 21 enters the annular groove 121, the top of the top limiting roller 22 contacts the top inner wall of the annular groove 121, and the bottom of the bottom limiting roller 22 corresponds to the bottom inner wall of the annular groove 121.

[0064] The elastic telescopic rod 23 has one end connected to the center of the end of the limiting plate 21 away from the shaft 20, and the other end is fitted with a ball 24 that contacts the bottom of the vertical groove 51.

[0065] The bottom center of the annular groove 121 has a ball groove 29. When the ball 24 corresponds to the ball groove 29, the elastic telescopic rod 23 drives the ball 24 into the ball groove 29. When the ball 24 does not correspond to the ball groove 29, the elastic telescopic rod 23 is in a compressed state. When the limiting plate 21 moves so that the ball 24 corresponds to the ball groove 29, the center of the limiting plate 21 corresponds to the axis of the annular groove 121. The elastic telescopic rod 23 drives the ball 24 into the ball groove 29. Then, when the drive assembly continues to drive the material holding part to move, the material holding part can be rotated with the shaft 20 as the axis.

[0066] Preferably, the annular groove 121 in this embodiment is provided with an elastic reset element and a detection element;

[0067] The elastic reset component includes two sets of sliding blocks 30. Both sets of sliding blocks 30 are slidably disposed in the annular groove 121 through the arc-shaped sliding groove on the inner wall of the annular groove 121. When the limiting plate 21 rotates with the shaft 20 in the annular groove 121, it squeezes the two sets of sliding blocks 30 to move along the arc-shaped sliding groove.

[0068] As can be seen from the attached diagram, one set of sliding blocks 30 is located at the upper end of the inner wall of the annular groove 121, and is used to contact the end of the top limiting roller 22 that rotates counterclockwise with the limiting plate 21. Another set of sliding blocks 30 is located at the lower end of the inner wall of the annular groove 121, and is used to contact the end of the top limiting roller 22 that rotates counterclockwise with the limiting plate 21. The counterclockwise rotation here is the flipping of the material holding shell 6 with the outer end facing up and the inner end facing down. After the limiting plate 21 enters the annular groove 121, the drive assembly continues to drive the material holding part. At this time, the material holding part drives the shaft 20, the shaft 20 drives the limiting plate 21, the limiting plate 21 rotates in the annular groove 121, and when the limiting plate 21 rotates, it pushes the corresponding sliding block 30 to move through the limiting roller 22.

[0069] The side of the sliding block 30 away from the limiting roller 22 is connected to the limiting block 32 fixed on the inner wall of the annular groove 121 through the arc-shaped elastic element 31. When the sliding block 30 moves, it squeezes the arc-shaped elastic element 31. When it is reset in the future, the limiting plate 21 can be driven to rotate the material holding part to reset to the initial state under the action of the arc-shaped elastic element 31. It should be noted that when the driving component makes the material holding part downward, the ball 24 can be disengaged from the ball groove 29 under the action of gravity.

[0070] The detection element is located on the outside of a ring 12. Only one set of detection elements is required. The detection element includes a pressure sensor 11 located at the bottom of a ball groove 29. The pressure sensor 11 is electrically connected to an external controller. After receiving the pressure signal from the elastic telescopic rod 23, the pressure sensor 11 sends a signal to the external controller to control the telescopic device 28 to work.

[0071] Please see the appendix Figure 6 Preferably, the drive assembly of this embodiment includes an electrical component housing 9 disposed on the side of the two sets of vertical frames 5 facing the mixer 1. The electrical component housing 9 is provided with a winding roller 15 driven by a rotating device. Both ends of the outer wall of the winding roller 15 are wound with pull ropes 13. One end of each of the two sets of pull ropes 13 passes around the guide energy storage drive device 14 disposed on the vertical frame 5 and is respectively connected to the top front and rear outer ends of the material holding shell 6. The rotating device is electrically connected to an external controller. The rotating device is, for example, a servo motor and a reducer. When the weighing device 8 detects that the weight of the material holding part reaches a preset threshold, the weighing device 8 sends a signal to make the rotating device work. The rotating device drives the winding roller 15 to wind or unwind the pull ropes 13, thereby moving the material holding shell 6. It should be noted that the pull ropes 13 are connected to the top front and rear outer ends of the material holding shell 6 so that the sliding mechanism and the guide part can be connected to drive the material holding shell 6 to flip.

[0072] The drive assembly also includes a rotating device 16 disposed inside the electrical component housing 9. The output end of the rotating device 16 is provided with a drive gear 17. One end of the drive gear 17 movably passes through the side wall of the electrical component housing 9. The outer wall of the mixer 1 is fixedly fitted with a toothed ring 10 for meshing with the drive gear 17. The rotating device 16 is, for example, a servo motor and a reducer. When unloading, the rotating device 16 can be opened, and the rotating device 16 drives the drive gear 17. Through the cooperation of the drive gear 17 and the toothed ring 10, the guide frame assembly, the material holding assembly, the drive assembly, and the movable ring 4 move in a circular motion relative to the mixer 1, so that the unloaded raw materials are evenly distributed in various areas of the mixer 1, thereby improving the quality of phosphogypsum concrete preparation.

[0073] Please see the appendix Figure 7 As a preferred embodiment, the guiding energy storage drive device 14 includes an L-shaped frame 33. There are two sets of L-shaped frames 33, which are respectively disposed on the top of the two sets of annular parts 12. The outer wall of the transverse part of the L-shaped frame 33 is movably sleeved with a sleeve 34 for the pull rope 13 to pass through through a bearing. Each of the two sets of L-shaped frames 33 is fixedly provided with a support frame 35 at one end. A driven shaft 36 is transversely rotatably provided at the top between the two sets of support frames 35. The end of the driven shaft 36 and the sleeve 34 are connected by a gear set 37. The gear set 37 consists of two sets of meshing gears. When the pull rope 13 pulls the material holding shell 6 to move, the pull rope 13 rubs against the sleeve 34, causing the sleeve 34 to rotate relative to the L-shaped frame 33. The rotation of the sleeve 34 drives the driven shaft 36 to rotate through the gear set 37.

[0074] A toothed gear 38 is fitted on the outer wall of the driven shaft 36. A drive shaft is rotatably provided at the bottom between the two sets of support frames 35. A torsion spring is provided at the connection between the drive shaft and the support frame 35. A driven gear 39 that meshes with the toothed gear 38 is fitted on the outer wall of the drive shaft. A circular roller is fitted on the outer wall of the drive shaft. The outer circumference of the circular roller is uniformly provided with protrusions 40 for contacting the top outer end of the tilting material holding part. When the top outer end of the material holding part contacts the outer wall of a protrusion 40, the toothless section on the toothed gear 38 corresponds to the driven gear 39.

[0075] When the material holding part is pulled upward by the pull rope 13, the drive shaft rotates under the action of the sleeve 34, gear set 37, driven shaft 36, toothed gear 38, and driven gear 39. When the material holding shell 6 flips over and contacts the outer wall of the protrusion 40 on the roller, the toothless section on the toothed gear 38 corresponds to the driven gear 39. Therefore, the drive shaft drives the roller to rotate and reset under the action of the torsion spring. When the roller rotates, it intermittently pushes the outer end of the material holding part through the protrusion 40, causing the material holding part to vibrate, so that the material in the material holding part is quickly discharged from the discharge port 26. It should be noted that the diameter of the roller is larger than the diameter of the toothed gear 38 and the driven gear 39 to prevent the flipped material holding part from contacting them.

[0076] It also includes an elastic connecting rod 18, one end of which is connected to the end of the pull rope 13 away from the winding roller 15, and the other end is connected to the top outer end of the material holding shell 6. This allows the material holding part to reciprocate and vibrate when the protrusion 40 intermittently pushes against the outer end of the material holding part.

[0077] A method for preparing phosphogypsum concrete, utilizing the aforementioned preparation apparatus, specifically includes the following steps:

[0078] S1: Prepare the raw materials needed to prepare phosphogypsum concrete, such as phosphogypsum powder, cement, and mineral powder.

[0079] First, one of the raw materials is put into the feeding section until the weighing section detects that the raw material in the feeding section has reached the preset threshold. At this time, the feeding of the raw material into the feeding section is stopped, and the weighing section controls the drive component to drive the feeding section to move along the guide section. After the feeding section moves to the designated position at the top of the guide section, the feeding section continues to move. With the cooperation of the guide section and the connecting sliding mechanism, the feeding section is driven to flip over, so that the raw material in the feeding section is unloaded into the mixer 1.

[0080] S2: After the raw materials are put into the mixer 1, the material holding part is reset by the drive component, and the next raw material is weighed and added until all the raw materials required for the preparation of phosphogypsum concrete are put into the mixer 1. The raw materials are stirred by the mixer 1. After stirring, the discharge port of the mixer 1 is opened to discharge the prepared phosphogypsum concrete.

[0081] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
