Description

Technical Field

[0001] This invention relates to the field of concrete technology, specifically to an apparatus and process for preparing concrete based on slag powder. Background Technology

[0002] Concrete, or simply concrete, is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] Slag powder is often added during concrete production and mixed using mixing equipment. For example, Chinese invention patent CN102674782A can utilize basalt, slag, and limestone to prepare concrete admixtures, with addition amounts of 20%–35%, 10%–20%, and 5%–10%, respectively, improving the environment, reducing pollution, and conserving resources. During concrete mixing, the various components are not easily mixed evenly. For example, Chinese utility model patent CN206551219U uses a rotating drum inside the mixing tank. The inner wall of the drum has a first spiral blade, and the outer wall has a second spiral blade. When the rotating drum is driven by a power component, the first spiral blade rotates and transports the concrete from the upper part of the mixing tank downwards, while the second spiral blade rotates and transports the concrete from the lower part of the mixing tank upwards. The concrete circulates within the mixing tank, achieving a uniform mixing effect.

[0004] Although the above-mentioned device can mix concrete, the stones generated during material feeding will concentrate and sink to the bottom during homogenization. The fixed spiral blades cannot transport the stones at the bottom, making it difficult to guarantee the quality of the produced concrete. Therefore, we propose a concrete preparation device and process based on slag powder to solve the above problems. Summary of the Invention

The hinge seats are movably disposed within the lower transmission port. One end of each hinge seat is fixedly connected to the end of the slide away from the mixing tank. The other end of each hinge seat is hinged to one end of the long connecting rod. The other end of the long connecting rod is hinged to one end of the transmission arm. The transmission arm is hinged to the top of the support seat. The bottom end of the support seat is fixedly connected to both sides of the top of the support frame.

[0012] Preferably, the distance from the hinge point of the transmission arm and the support seat to the long connecting rod is less than the distance from the hinge point of the transmission arm and the support seat to the transmission connecting rod.

The spline rod is slidably sleeved in the spline sleeve. The stirring rod is evenly distributed around the circumference and has a paddle-shaped structure.

[0015] A process for preparing concrete based on slag powder is also provided, comprising the following steps: S1. The raw materials for concrete preparation and the added slag powder are put into the mixing tank. S2. When the servo motor is powered on, it drives the active shaft to rotate in a circular motion. The active shaft drives the driven shaft to rotate, and the driven shaft drives the active component to work. The active component reciprocates and lifts at the top of the support frame. S3. While the active component is working, it works in conjunction with the transmission component to drive the mixing tank to reciprocate up and down at the bottom of the support frame. The direction of the up and down movement of the mixing tank is opposite to the direction of the up and down movement of the active component. S4. While the active rotating shaft rotates, it drives the agitator to rotate synchronously. The agitator mixes and stirs the materials in the mixing tank, and at the same time, it turns the materials in the mixing tank.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Driven by the servo motor, the active component is driven to work through the cooperation of various components. The active component reciprocates and lifts at the top of the support frame. At the same time, the active component, in conjunction with the transmission component, drives the mixing tank to reciprocate and lift at the bottom of the support frame. The lifting direction of the mixing tank is opposite to that of the active component, thereby turning the material in the mixing tank up and down. Meanwhile, the servo motor, in conjunction with the active rotating shaft, drives the mixing component to rotate circumferentially, thereby mixing the material in the mixing tank and preventing the material from stratifying and settling during the mixing process. 2. When the active component rises, the agitator moves upwards along with it, while the mixing tank moves downwards, causing the agitator to stir and tumble the upper layer of material in the mixing tank. When the active component moves downwards, the mixing tank rises simultaneously, allowing the agitator to penetrate into the lower layer of material in the mixing tank. Combined with the circumferential rotation of the agitator itself, this significantly improves the uniformity of material mixing. 3. During the mixing process, the mixing shaft can slide within the guide hole. The elasticity of the spring allows the mixing rod to generate a certain buffer when it comes into contact with the material. At the same time, when the end of the mixing shaft contacts the bottom wall of the mixing tank, it plays a role in retraction and buffering, preventing the end of the mixing component from impacting the mixing tank and causing damage to the mixing component. Meanwhile, the cooperation between the anti-detachment groove and the anti-detachment slider can effectively prevent the mixing shaft from detaching from the guide hole, ensuring the stability of the mixing operation.

[0019] 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.

[0020] Example 1 Reference Figure 1 , 2This is the first embodiment of the present invention, which provides a concrete preparation device based on slag powder. The device includes a base plate 1, with the bottom end of a support frame 2 fixedly connected to the top of the base plate 1. The inner walls of opposite sides of the support frame 2 are respectively provided with recessed grooves 3. Slide seats 4 are slidably provided at the bottom of the grooves 3. Slide seats 4 are respectively fixedly connected to the outer walls of both sides of a mixing tank 5. The ends of slide seats 4 away from the mixing tank 5 are respectively fixedly connected to one end of a transmission assembly 6. The transmission assembly 6 is movably disposed on the outside of the support frame 2, and the other end of the transmission assembly 6 is fixedly connected to both sides of the top of an active assembly 7. The active assembly 7 and the mixing tank 5 are movably disposed within the support frame 2. Slide seats 13 are respectively fixedly connected to both ends of the active assembly 7. Slide seats 13 are slidably disposed at the top of the grooves 3. One side of component 7 is driven by a driven shaft 12, which is rotatably mounted on a support bar 9. One end of the support bar 9 is fixedly connected to the outer wall of the top side of the support frame 2. The other end of the driven shaft 12 is driven by a drive shaft 11, which is rotatably mounted at the top center of the support frame 2. The top of the drive shaft 11 is fixedly connected to the output shaft of a servo motor 8, which is fixedly mounted on the top of the support frame 2. The bottom end of the drive shaft 11 slides through the rear end of the drive component 7 and is slidably engaged with a stirring component 10. The stirring component 10 is rotatably connected to the bottom end of the drive component 7 and is movably disposed inside the mixing tank 5. A fan-shaped discharge port is provided at the bottom of the mixing tank 5, and a fan-shaped door is installed at the fan-shaped discharge port for opening and closing the fan-shaped discharge port.

[0021] A process for preparing concrete based on slag powder includes the following steps: S1. The raw materials for concrete preparation and the added slag powder are put into the mixing tank 5. S2. When the servo motor 8 is powered on, the servo motor 8 drives the active rotating shaft 11 to rotate in a circle. The active rotating shaft 11 drives the driven rotating shaft 12 to rotate. The driven rotating shaft 12 drives the active component 7 to work. The active component 7 achieves reciprocating lifting and lowering work at the top inside the support frame 2. S3. While the active component 7 is working, it works in conjunction with the transmission component 6 to drive the mixing tank 5 to reciprocate up and down at the bottom of the support frame 2. The direction of the up and down movement of the mixing tank 5 is opposite to the direction of the up and down movement of the active component 7. S4. While the active rotating shaft 11 rotates, it drives the stirring component 10 to rotate synchronously. The stirring component 10 stirs and mixes the material in the mixing tank 5, and at the same time, it turns the material in the mixing tank 5.

[0022] Example 2 Reference Figure 1-8This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, the support bar 9 has an L-shaped structure, and the bottom of the support bar 9 is hollow and has a transmission cavity 91. The top end of the driven shaft 12 is connected to the pulley fixed to the top end of the driving shaft 11 through a fixed pulley and a transmission belt. The bottom end of the driven shaft 12 is fixedly connected to the driving bevel gear 121, which is rotatably disposed in the transmission cavity 91. When the servo motor 8 drives the driving shaft 11 to rotate, the driving shaft 11 drives the driven shaft 12 to rotate through the belt transmission mechanism, thereby driving the operation of the active component 7.

[0023] Specifically, the active component 7 includes a movable seat 71, a sliding opening 72, a sliding frame 73, a connecting plate 74, and a transmission shaft 75. The outer walls of both ends of the movable seat 71 are fixedly connected to the sliding seat 13. A sliding opening 72 is provided on one side of the movable seat 71. A sliding frame 73 is slidably provided in the sliding opening 72. A connecting plate 74 is fixedly installed in the sliding frame 73. One end of the transmission shaft 75 is fixedly connected to the eccentric part of the connecting plate 74. The other end of the transmission shaft 75 is rotatably connected to the support bar 9 and is fixedly connected to the end of the driven bevel gear 751. The driven bevel gear 751 meshes with the active bevel gear 121.

[0024] When the servo motor 8 is powered on, it drives the active shaft 11 to rotate in a circular motion. The active shaft 11 drives the driven shaft 12 to rotate through the belt drive mechanism. The driven shaft 12 drives the fixed active bevel gear 121 to rotate. The active bevel gear 121 drives the meshing driven bevel gear 751 to rotate. The driven bevel gear 751 then drives the fixed transmission shaft 75 to rotate. When the transmission shaft 75 rotates, it drives the connecting plate 74 at the eccentric position to rotate in a circular motion around the transmission shaft 75. This drives the slide frame 73 to move back and forth horizontally within the slide opening 72. At the same time, the driving force is converted into the vertical lifting and lowering of the movable seat 71. The movable seat 71 achieves stable reciprocating lifting and lowering motion of the top of the movable seat 71 within the support frame 2 through the guide cooperation between the slide block 13 and the slide groove 3. Its lifting and lowering stroke is precisely controlled by the eccentricity of the connecting plate 74.

[0025] Furthermore, a sliding hole 711 is provided through the side of the movable seat 71 away from the sliding port 72. The active rotating shaft 11 is slidably sleeved in the sliding hole 711. The vertical section of the sliding port 72 is a cross-shaped structure. A piano-type sealing plate 76 is fixedly connected to the opening of the sliding port 72. The piano-type sealing plate 76 is fixedly sleeved with a support bearing 77. The transmission shaft 75 is rotatably sleeved in the support bearing 77. The setting of the piano-type sealing plate 76 ensures the sealing of the interior of the sliding port 72.

[0026] Specifically, the support frame 2 has a U-shaped structure, the slide 3 has a T-shaped structure, the bottom of both sides of the support frame 2 is provided with a lower transmission port 21, and the top of the support frame 2 is provided with an upper transmission port 22.

[0027] Specifically, the transmission components 6 are arranged symmetrically. The transmission components 6 include hinge seats 61, long connecting rods 62, transmission arms 63, support seats 64, transmission connecting rods 65, and connecting seats 66. The hinge seats 61 are movably disposed in the lower transmission port 21. One end of the hinge seat 61 is fixedly connected to the end of the slide seat 4 away from the mixing tank 5. The other end of the hinge seat 61 is hinged to one end of the long connecting rod 62. The other end of the long connecting rod 62 is hinged to one end of the transmission arm 63. The transmission arm 63 is hinged to the top of the support seat 64. The bottom end of the support seat 64 is fixedly connected to the top two sides of the support frame 2. The end of the transmission arm 63 away from the long connecting rod 62 is hinged to one end of the transmission connecting rod 65. The other end of the transmission connecting rod 65 movably passes through the upper transmission port 22 and is hinged to the connecting seat 66 at its rear end. The connecting seat 66 is fixedly connected to the top two sides of the movable seat 71.

[0028] Furthermore, the distance from the hinge point of the transmission arm 63 and the support seat 64 to the long connecting rod 62 is less than the distance from the hinge point of the transmission arm 63 and the support seat 64 to the transmission connecting rod 65, thereby enabling the transmission arm 63 to form a lever mechanism during transmission.

[0029] When the movable seat 71 reciprocates and moves up and down, the transmission component 6 works in coordination. The lifting and lowering motion of the active component 7 drives the transmission components 6 on both sides synchronously through the linkage mechanism. When the active component 7 rises, the transmission component 6 drives the slide 4 to move through the lever principle. The slide 4 drives the mixing tank 5 to move down along the slide groove 3. Conversely, when the active component 7 descends, the mixing tank 5 moves up, forming a reverse linkage.

[0030] Specifically, the end of the active rotating shaft 11 furthest from the servo motor 8 is coaxially fixedly connected to a spline rod 111. The stirring component 10 includes a spline sleeve 101, a support rod 102, an upper sliding hole 103, a guide sliding hole 104, a spring 105, a stirring shaft 106, a stirring rod 107, an anti-detachment groove 108, and an anti-detachment slider 109. One end of the spline sleeve 101 is rotatably connected to the bottom end of the movable seat 71, and the other end of the spline sleeve 101 is fixedly connected to one end of the support rod 102. The other end of the support rod 102 is recessed with a guide sliding hole 104, which slides and engages one side of the stirring shaft 106. Multiple stirring rods 107 are fixedly connected to the other end of the stirring shaft 106. The stirring rods 107 are movably disposed inside the stirring tank 5. The end of the stirring shaft 106 furthest from the stirring rods 107 is fixedly connected to one end of the spring 105, and the other end of the spring 105 is fixedly connected to the inner wall of the guide sliding hole 104 furthest from the stirring shaft 106.

[0031] When the active rotating shaft 11 rotates, it drives the fixed splined rod 111 to rotate circumferentially. The splined rod 111 drives the snap-fit ​​stirring element 10 to rotate circumferentially. That is, the rotation of the active rotating shaft 11 synchronously drives the support rod 102 to rotate circumferentially through the spline transmission. The support rod 102 drives the snap-fit ​​stirring shaft 106 to rotate synchronously. The stirring rod 107 at the bottom of the stirring shaft 106 performs a 360° circumferential motion. The stirring rod 107 stirs and mixes the material in the mixing tank 5. At the same time, the stirring rod 107, under the reciprocating lifting and lowering operation of the movable seat 71, works in conjunction with the reciprocating lifting and lowering operation of the mixing tank 5. The stirring rod 107 stirs and turns the material in each layer of the mixing tank 5. During the stirring process of the stirring rod 107, the stirring shaft 106 can move through the guide sliding hole 10. The inner sliding mechanism of the spring 105 allows the stirring rod 107 to generate a certain buffer when it comes into contact with the material. At the same time, when the end of the stirring shaft 106 contacts the bottom wall of the mixing tank 5, it plays a role in retraction and buffering, preventing the end of the stirring shaft 106 from colliding with the mixing tank 5 and causing damage to the stirring shaft 106. Meanwhile, the cooperation between the anti-detachment groove 108 and the anti-detachment slider 109 can effectively prevent the stirring shaft 106 from detaching from the guide sliding hole, ensuring the stability of the stirring operation. Furthermore, under the elastic force of the spring 105, the stirring rod 107 moves up and down while stirring in a circular motion, ultimately forming a composite stirring effect of "rotational shearing + axial tumbling", which effectively breaks up material agglomerates and improves the mixing uniformity of slag powder and concrete raw materials.

[0032] Furthermore, the inner walls on both sides of the guide slide hole 104 are respectively provided with anti-detachment grooves 108, and anti-detachment sliders 109 are respectively slidably engaged in the anti-detachment grooves 108. The anti-detachment sliders 109 are respectively fixedly connected to the outer wall of the stirring shaft 106 away from the stirring rod 107. The end of the support rod 102 away from the guide slide hole 104 is provided with an upper sliding hole 103. The diameter of the upper sliding hole 103 is larger than the outer diameter of the spline rod 111. The spline rod 111 is slidably sleeved in the spline sleeve 101. The stirring rods 107 are evenly distributed around the circumference and the stirring rods 107 have a paddle-shaped structure.

[0033] The working principle and process are as follows: The raw materials for concrete preparation and the added slag powder are put into the mixing tank 5. The servo motor 8 is powered on and started, driving the active rotating shaft 11 to rotate in a circular motion. The active rotating shaft 11 drives the driven rotating shaft 12 to rotate through the belt transmission mechanism. The driven rotating shaft 12 drives the fixed active bevel gear 121 to rotate. The active bevel gear 121 drives the meshing driven bevel gear 751 to rotate. The driven bevel gear 751 then drives the fixed transmission shaft 75 to rotate. When the transmission shaft 75 rotates, it drives the connecting plate 74 at the eccentric position to rotate in a circular motion around the transmission shaft 75. This, in turn, drives the sliding frame 73 to move back and forth in the sliding port 72, while converting the driving force into the vertical movement of the movable seat 71. The movable seat 71 is raised and lowered. Through the guide cooperation between the slide seat 2 13 and the slide groove 3, the movable seat 71 can achieve stable reciprocating lifting and lowering motion of the top of the movable seat 71 within the support frame 2. Its lifting stroke is precisely controlled by the eccentricity of the connecting plate 74. At the same time, when the movable seat 71 is reciprocating and lowering, the transmission component 6 works in coordination. The lifting and lowering motion of the active component 7 drives the transmission components 6 on both sides synchronously through the linkage mechanism. When the active component 7 rises, the transmission component 6 drives the slide seat 4 to move through the lever principle. The slide seat 4 drives the mixing tank 5 to move down along the slide groove 3. Conversely, when the active component 7 falls, the mixing tank 5 moves up, forming a reverse linkage. Through the rotational cooperation of the support bearing 77 and the sealing protection of the piano-type sealing plate 76, the transmission efficiency and structural sealing are ensured.Simultaneously, the active rotating shaft 11 drives the fixed spline rod 111 to rotate circumferentially, and the spline rod 111 drives the snap-fit ​​stirring element 10 to rotate circumferentially. That is, the rotation of the active rotating shaft 11 synchronously drives the support rod 102 to rotate circumferentially through the spline transmission. The support rod 102 drives the snap-fit ​​stirring shaft 106 to rotate synchronously. The stirring rod 107 at the bottom of the stirring shaft 106 performs a 360° circumferential motion. The stirring rod 107 stirs and mixes the material in the mixing tank 5. At the same time, under the reciprocating lifting and lowering operation of the movable seat 71, the stirring rod 107 works in conjunction with the reciprocating lifting and lowering operation of the mixing tank 5. The stirring rod 107 stirs and turns the material in each layer of the mixing tank 5. During the stirring process of the stirring rod 107, the stirring shaft 106 can slide in the guide sliding hole 104. The elasticity of the spring 105 allows the stirring rod 107 to produce a certain amount of heat when it comes into contact with the material. The mixing shaft 106 provides a certain buffer and acts as a retraction and buffer when its end contacts the bottom wall of the mixing drum 5, preventing damage to the mixing shaft 106 due to impact. Simultaneously, the anti-detachment groove 108 and the anti-detachment slider 109 effectively prevent the mixing shaft 106 from detaching from the guide hole, ensuring the stability of the mixing operation. Furthermore, the spring force of the spring 105 causes the mixing rod 107 to move up and down while simultaneously mixing in a circular motion, ultimately forming a composite mixing effect of "rotational shearing + axial tumbling," effectively breaking up material agglomerates and improving the uniformity of mixing between slag powder and concrete raw materials. After mixing, the material is discharged and collected through a fan-shaped discharge port at the bottom of the mixing drum 5. A fan-shaped door is installed at the discharge port, which closes during mixing to seal the bottom of the mixing drum 5.

[0034] 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.
