Description

Technical Field

[0001] The present invention relates to the technical field of recycling of construction waste, and particularly to a mixing device and an automatic batching system for recycled inorganic mixture. Background Art

[0002] With the increasing global awareness of sustainable development and environmental protection, the construction industry is seeking more environmentally friendly and resource-efficient construction methods. Recycled inorganic mixtures (such as recycled concrete, bricks, etc. made from waste building materials) are an important way of resource recycling. While reducing the amount of construction waste landfilled, they also provide high-quality building materials. Such materials not only help reduce the costs of new construction projects but also significantly reduce environmental impacts.

[0003] Despite the broad application prospects of recycled inorganic mixtures, the issues of mixing uniformity and efficiency in their production process remain one of the main challenges restricting their widespread use. Traditional mixing equipment usually has the following deficiencies: (1) Uneven mixing. Many existing mixing devices are difficult to ensure sufficient mixing between materials of different components. Especially when there are large differences in the particle sizes of the materials, layering is likely to occur. (2) Low degree of automation. Most traditional systems rely on manual operation for batching, water supply, and discharging. This not only increases labor costs but may also lead to human errors, affecting the quality consistency of the final product. (3) Poor flexibility. Facing different formulation requirements or changes in raw material characteristics, existing equipment often lacks the ability to quickly adjust, limiting its applicability in diverse application scenarios.

[0053] The following detailed description of the specific embodiments of the present disclosure is provided in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0054] In the present disclosure, unless otherwise stated, the directional terms such as "upper, lower, left, right" are usually defined according to the direction of the drawing surface of the accompanying drawings, and "inner, outer" refer to the inside and outside of the contour of the relevant components. In addition, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0055] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and defined, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0056] As Figures 1 to 4 shown, the present disclosure provides a mixing device for recycled inorganic mixture, which includes a barrel body 10, a stirring assembly 20 and a mixture conveying pipe 30. A stirring cavity 11 is formed inside the barrel body 10. An inlet 12 for water, a first feeding port 13, a second feeding port 14 and a discharging port 15 are formed on the barrel body 10 and are all communicated with the stirring cavity 11. The stirring assembly 20 includes a driving member 21 and a stirring member 22. The driving member 21 is located outside the barrel body 10 and is installed on the barrel body 10. The stirring member 22 is located inside the stirring cavity 11. The driving member 21 is connected to the stirring member 22 and is used to drive the stirring member 22 to rotate. The mixture conveying pipe 30 has a cavity 31. An input port 32 and an output port 33 are formed on the mixture conveying pipe 30 and are all communicated with the cavity 31. The input port 32 is communicated with the discharging port 15, and the output port 33 is used to communicate with the inlet of a mixture collecting system 83.

[0057] Among them, a stirring cavity 11 is formed inside the barrel body 10 for accommodating materials to be processed (cement, construction waste and water).

[0058] Through the above technical solution, the materials to be processed (cement, construction waste and water) can enter the stirring cavity 11 through the water inlet 12, the first feeding port 13 and the second feeding port 14 on the barrel body 10 respectively. And, through the arranged driving member 21 and stirring member 22, the driving member 21 can drive the stirring member 22 inside the stirring cavity 11 to quickly and fully stir the filling materials and water to form a mixture. After the stirring is completed, the mixture can flow out from the discharging port 15 on the barrel body 10. In addition, through the arranged mixture conveying pipe 30, the mixture discharged from the barrel body 10 can enter the mixture conveying pipe 30, and the output port 33 of the mixture conveying pipe 30 is used to be connected with the inlet of the mixture collecting system 83 so as to convey the mixed mixture to a storage container. With such an arrangement, the preparation work of the recycled inorganic mixture can be effectively carried out, the uniform mixing and smooth conveying of the mixture can be ensured, and the working efficiency can be improved.

[0059] As an implementation manner, as Figure 2As shown, the stirring member 22 includes a stirring shaft 221 and spiral blades 222 formed on the stirring shaft 221. The mixing device 100 further includes a flow guiding member 40. The spiral blades 222 are located in the stirring chamber 11 and are in a spiral rising shape. The stirring shaft 221 extends in the vertical direction and passes through the barrel 10 to be connected to the driving member 21. The flow guiding member 40 is located in the stirring chamber 11 and is detachably connected to the barrel 10. The flow guiding member 40 is used to sleeved on the stirring member 22. Along the direction from top to bottom, the cross-sectional area of the flow guiding member 40 gradually decreases.

[0060] Among them, the spiral blades 222 are installed on the stirring shaft 221 in a spiral rising manner. With such a design, it can help the mixture achieve a cyclic movement in the up and down directions during the stirring process, so as to achieve a better mixing effect.

[0061] Among them, the stirring shaft 221 passes through the barrel 10 and is connected to the driving member 21. The driving member 21 can be installed outside the barrel 10 and provide rotational power to rotate the stirring shaft 221. With such a setting, not only can the effectiveness of stirring be ensured, but also the maintenance and servicing of the mixing device can be facilitated.

[0062] Among them, when viewed from the top to the bottom direction, the cross-sectional area of the flow guiding member 40 gradually decreases. Such a design helps to control the flow path of the mixture, enabling the mixture to be more evenly mixed during the stirring process. At the same time, it can also increase the number of turns of the mixture in the stirring chamber 11. That is to say, since the cross-sectional area of the flow guiding member 40 gradually decreases along the direction from top to bottom, therefore, the flow guiding member 40 of this shape can cause the mixture to be more strongly guided and compressed during the downward movement, resulting in a change in the flow path of the mixture, increasing the chance of the mixture contacting the stirring blades, as well as the mutual friction and collision between the mixtures, thereby increasing the number of turns of the mixture and further improving the mixing efficiency.

[0063] Optionally, an annular skirt can be provided at the top of the flow guiding member 40. The flow guiding member 40 can be fixed to the inner wall of the barrel 10 by fixing bolts passing through the annular skirt. In this way, the detachable design of the flow guiding member 40 can facilitate the cleaning and maintenance work of the flow guiding member 40, which helps to extend the service life of the mixing device 100.

[0064] Optionally, a plurality of cutting blades are provided on the edge of the spiral blades 222. Specifically, the plurality of cutting blades can be installed on the edge of the spiral blades 222 by bolts. By providing the cutting blades, not only can larger particles or agglomerates be effectively broken into smaller and more uniform ones, but also the contact area between the mixtures can be increased by chopping and shearing the mixture, thereby promoting more thorough mixing, which helps to improve the uniformity and quality of the final mixture.

[0065] As an implementation, as Figure 2 shown, the mixing device 100 further includes a flexible coupling 50 and two connecting shafts 51. The barrel 10 includes a barrel body 16 and a cover plate 17. The cover plate 17 is covered on the opening of the barrel body 16 to jointly define a stirring cavity 11 with the barrel body 16. A through hole is formed on the cover plate 17. The stirring shaft 221 is configured as a telescopic rod structure. The stirring shaft 221 includes a first pipe section 2211 and a second pipe section 2212 sleeved on the first pipe section 2211. The first pipe section 2211 is slidably connected inside the second pipe section 2212. One end of the second pipe section 2212 away from the first pipe section 2211 passes through the through hole out of the stirring cavity 11 to be connected with one end of the flexible coupling 50. The other end of the flexible coupling 50 is connected with the drive shaft of the driving member 21. An annular groove 18 extending along the circumferential direction of the stirring cavity 11 is formed on the inner wall of the barrel body 16. The annular groove 18 is configured as a wavy structure. A spiral blade 222 is formed on the first pipe section 2211. The two connecting shafts 51 are respectively located on the opposite sides of the first pipe section 2211. One ends of the two connecting shafts 51 away from the first pipe section 2211 are both slidably connected to the annular groove 18.

[0066] Specifically, when the driving member 21 is started, the rotational power can be transmitted to the stirring shaft 221 through the flexible coupling 50, so that the stirring shaft 221 starts to rotate. As the stirring shaft 221 rotates, the spiral blade 222 starts to push the mixed material to move circumferentially. In addition, since the ends (the ends away from the first pipe section 2211) of the two connecting shafts 51 are slidably connected in the wavy annular groove 18, when the stirring shaft 221 rotates, the two connecting shafts 51 can move along a wavy path. Designed in this way, the connecting shafts 51 can not only rotate in the horizontal direction (i.e., in the circumferential direction of the stirring cavity 11), but also cause the stirring shaft 221 to have a tendency to move up and down due to the shape undulation of the annular groove 18. Among them, this up and down movement is the result of the wavy structure guiding the connecting shafts 51 to move along the high and low change path of the annular groove 18.

[0067] Among them, the stirring member 22 moves up and down while rotating, so that the mixed material can not only be subjected to the shear force and driving force brought by rotation, but also be subjected to the additional turning and disturbance brought by the up and down movement. In this way, the interaction between the mixed materials can be greatly increased, thereby promoting more thorough mixing. Especially for the mixed materials that are difficult to be evenly dispersed, this design can significantly improve the mixing efficiency and quality.

[0068] Among them, through the arrangement of the two connecting shafts 51, additional support points can be provided during the stirring process, which can effectively reduce the swing or deviation that may occur when the stirring shaft 221 rotates at a high speed, so as to ensure that the stirring process is more stable.

[0069] As an implementation, as Figure 2As shown, the position of the connecting shaft 51 is higher than the positions of the spiral blade 222 and the deflector 40. The deflector 40 has opposite first and second open ends. The position of the first open end is higher than the top of the spiral blade 222, and the position of the second open end is lower than the bottom of the spiral blade 222.

[0070] Among them, since the position of the connecting shaft 51 is higher than the spiral blade 222 and the deflector 40, it is possible to avoid the situation of obstructing the operation of the spiral blade 222.

[0071] Among them, the first open end abuts against the inner wall of the mixing chamber 11. In this way, it is possible to effectively prevent the mixture from directly passing through the gap between the deflector 40 and the mixing chamber 11 without being fully mixed, and all the mixture must pass through the inside of the deflector 40 or the action area of the spiral blade 222, so as to ensure the full mixing of the mixture.

[0072] As an implementation manner, as Figure 3 shown, the mixing device 100 further includes fixing blocks 52, a first mounting plate 53, a second mounting plate 54, a first ball 55 and a second ball 56. Fixing blocks 52 are provided at the ends of the two connecting shafts 51 far from the first pipe section 2211. A first arc-shaped groove 521 for accommodating the first ball 55 is formed on the top surface of the fixing block 52, and a second arc-shaped groove 522 for accommodating the second ball 56 is formed on the bottom surface of the fixing block 52. The first mounting plate 53 is detachably connected to the top of the fixing block 52, and a first tapered hole 531 adapted to the first ball 55 is formed on the first mounting plate 53. Part of the first ball 55 protrudes from the first tapered hole 531 and is slidably connected to the top of the annular groove 18. The second mounting plate 54 is detachably connected to the bottom of the fixing block 52, and a second tapered hole adapted to the second ball 56 is formed on the second mounting plate 54. Part of the second ball 56 protrudes from the second tapered hole and is slidably connected to the bottom of the annular groove 18.

[0073] Among them, through the design of the fixing blocks 52, the first mounting plate 53, the second mounting plate 54, the first ball 55 and the second ball 56, the connecting shaft 51 can not only be stably supported, but also flexibly move along the path of the wavy annular groove 18 during the mixing process. Moreover, the rolling contact between the balls and the annular groove 18 can reduce the friction force, making the entire mixing operation more smooth and efficient. In addition, the first mounting plate 53 and the second mounting plate 54 are designed to be detachable, which enables the staff to conveniently check, clean or replace worn parts such as the first ball 55 and the second ball 56, thereby extending the service life of the equipment and maintaining the best performance.

[0074] Optionally, as Figure 3 shown, the first mounting plate 53 and the second mounting plate 54 can both be mounted on the fixing block 52 by screws.

[0075] As an implementation manner, as Figure 3 shown, the top surface of the fixed block 52 has a first central axis arranged along the length direction of the fixed block 52, the bottom surface of the fixed block 52 has a second central axis arranged along the length direction of the fixed block 52, there are multiple first arc grooves 521, and the multiple first arc grooves 521 are arranged at intervals along the length direction of the fixed block 52 and form a first arc groove 521 group. The first arc groove 521 group is located on the first central axis. Among them, the number of the first tapered holes 531, the number of the first balls 55 and the number of the first arc grooves 521 correspond one by one. There are multiple second arc grooves 522, and the multiple second arc grooves 522 are arranged at intervals along the length direction of the fixed block 52 and form a second arc groove 522 group. The second arc groove 522 group is located on the second central axis. Among them, the number of the second tapered holes and the number of the second balls 56 correspond one by one to the number of the second arc grooves 522.

[0076] Among them, by respectively arranging multiple first arc groove 521 groups and second arc groove 522 groups arranged at intervals on the top surface and the bottom surface of the fixed block 52, the pressure can be effectively dispersed and more uniform support can be provided. This can not only increase the overall stability of the device, but also reduce the risk of wear or damage caused by excessive local stress. In addition, the design of multiple balls enables the connecting shaft 51 to better adapt to the changing shape of the wavy annular groove 18, and good followability can be maintained both in terms of height change and curvature change. This helps the stirring shaft 221 to maintain a stable working state in a complex movement path.

[0077] As an implementation manner, as Figure 1 and 2 shown, the mixing device 100 further includes a transmission assembly 60. The mixture conveying pipe 30 includes a mixture conveying pipe body 34, a screw 35 and a partition 36. The partition 36 is located in the cavity 31 to separate a first cavity chamber 311 and a second cavity chamber 312. An input port 32 communicating with the first cavity chamber 311 is formed on the side wall of the first cavity chamber 311. The screw 35 extends along the axial direction of the mixture conveying pipe body 34. The first end of the screw 35 is located in the second cavity chamber 312 and is in transmission connection with the driving member 21 through the transmission assembly 60. The second end of the screw 35 passes through the partition 36 and is located in the first cavity chamber 311.

[0078] Among them, the transmission assembly 60 can smoothly transmit the rotational force of the driving member 21 to the screw 35, and can ensure the stability and continuity of power transmission throughout the process. This arrangement can not only improve the mixture transmission efficiency, but also reduce energy loss and mechanical wear.

[0079] Among them, when the mixture enters the first cavity 311 through the input port 32, under the rotation of the screw 35, the mixture gradually advances in the direction of the output port 33, that is, in the direction away from the partition 36.

[0080] Among them, the partition 36 can play a role in preventing the mixture from flowing into the second chamber.

[0081] Among them, by arranging the screw 35 in the mixture conveying pipe body 34, the mixture conveying pipe 30 can further mix the mixture while transmitting the mixture. The rotation of the screw 35, on the one hand, can apply shear force and driving force to the mixture, which can help break the mixture agglomeration and achieve a more uniform distribution. On the other hand, it can continuously stir the mixture containing particles of different densities, which can help maintain the uniformity of the mixture composition and prevent stratification and sedimentation.

[0082] As an implementation manner, as Figure 1 and 2 shown, the transmission assembly 60 includes a driving sprocket 61, a driven sprocket 62, a chain 63, a transmission rod 64, a first bevel gear 65 and a second bevel gear 66. The driving sprocket 61 is sleeved on the driving shaft of the driving member 21. The transmission rod 64 is located outside the barrel body 10 and is vertically arranged. The first end of the transmission rod 64 is sleeved with the driven sprocket 62. The second end of the transmission rod 64 is inserted into the second cavity 312 and is sleeved with the first bevel gear 65. The chain 63 is rotatably sleeved between the driving sprocket 61 and the driven sprocket 62. The first end of the screw 35 is sleeved with the second bevel gear 66, and the first bevel gear 65 meshes with the second bevel gear 66.

[0083] Specifically, when the driving member 21 is started, the driving sprocket 61 starts to rotate, and the rotational force is transmitted to the driven sprocket 62 through the chain 63. The driven sprocket 62 drives the transmission rod 64 to rotate, and then the first bevel gear 65 at the end (i.e., the bottom) of the transmission rod 64 rotates. And, since the first bevel gear 65 meshes with the second bevel gear 66, the second bevel gear 66 can rotate with the first bevel gear 65, so as to drive the screw 35 to rotate.

[0084] Among them, by using a transmission system composed of the chain 63, sprockets and bevel gears, efficient and smooth power transmission can be achieved. This design can not only reduce energy loss but also reduce the risk of wear of the transmission assembly 60.

[0085] As an implementation manner, as Figure 1 、 Figure 2 and Figure 4As shown, the mixing device 100 further includes a first switching valve 70, a second switching valve 71, a third switching valve 72, and a fourth switching valve 73. The first end of the first switching valve 70 is communicated with the first feeding port 13, and the second end of the first switching valve 70 is used to be communicated with the cement supply system 80. The first end of the second switching valve 71 is communicated with the second feeding port 14, and the second end of the second switching valve 71 is used to be communicated with the construction waste supply system 81. The first end of the third switching valve 72 is communicated with the water inlet 12, and the second end of the third switching valve 72 is used to be communicated with the water supply system 82. A discharge port 15 is formed at the bottom of the barrel body 16. The first end of the fourth switching valve 73 passes through the discharge port 15 and out of the mixing chamber 11 to be communicated with the input port 32 of the mixture conveying pipe 30. The second end of the fourth switching valve 73 is communicated with the second open end. The first switching valve 70, the second switching valve 71, the third switching valve 72, and the fourth switching valve 73 are all used to be electrically connected to the control system.

[0086] Among them, through the control system, the opening and closing states of the first switching valve 70, the second switching valve 71, and the third switching valve 72 can be respectively controlled, the adding amounts and times of cement, construction waste, and water can be accurately controlled, and the consistency of the mixture composition in each batch can be ensured. In addition, through the control system, the opening and closing state of the fourth switching valve 73 can be controlled, that is, the opening and closing of the discharge port 15 can be controlled, so as to achieve the purpose of controlling the conveying of the mixture in the barrel 10. That is to say, the entire feeding, water supply, and discharging processes can be automatically controlled. The control system can automatically adjust the states of each switching valve according to the preset program, reduce human intervention, and improve production efficiency.

[0087] It should be noted that the mixing device 100 has two working states. The first is the working state of only stirring without output, and the second is the working state of stirring while outputting.

[0088] Among them, the first working state is applicable to the initial stage of stirring, and the time is relatively short. That is, when the mixture just enters the barrel 10, in order to prevent the mixture from directly entering the mixture conveying pipe 30 through the output port 33 under the action of gravity, thereby affecting the preparation effect of the mixture, therefore, the control system can be used to close the fourth switching valve 73, so as to facilitate the mixing structure in the barrel 10 to stir and mix the mixture, and there is no need to carry out the mixture conveying work.

[0089] The second working state is applicable to the middle and late stages of stirring, which takes a longer time. That is, when the mixture in the barrel 10 is prepared by the stirring structure, the control system can be used to open the fourth switching valve 73. In this way, the prepared mixture enters the mixture conveying pipe 30 through the fourth switching valve 73 and the output port 33 in sequence, and the mixture conveying and filling work is carried out under the action of the screw 35. While the mixture in the barrel 10 is being conveyed to the mixture conveying pipe 30, new materials can enter the barrel 10 through the water inlet 12, the first feeding port 13 and the second feeding port 14 of the barrel 10. In this way, while realizing the mixture conveying, new mixture can also be prepared, forming an efficient circulation system. In addition, it should be supplemented that, on the one hand, the rotation speed of the screw 35 (for example, reducing the rotation speed of the screw 35) can be controlled to control the mixture conveying and filling speed, and on the other hand, the rotation speed of the stirring member 22 (for example, increasing the rotation speed of the stirring member 22) can be controlled to control the stirring speed. Such a setting can effectively improve the conveying efficiency of the mixing device 100.

[0090] In other words, since the mixing device 100 in the present disclosure switches from the first working state to the second working state, and the second working state is emphasized. Therefore, in the first working state, although the screw 35 is idling, the duration of this working state is short, and the working mode of the driving motor (such as a low-power standby mode) can be adjusted through the control system, without causing significant energy waste.
