Description

Technical Field

[0001] The present invention relates to the technical field of sand mixers, and particularly to an efficient planetary rotor sand mixer. Background Art

[0002] A sand mixer is a device that evenly mixes each component in molding sand and effectively coats the binder on the surface of sand grains. The sand mixer has the functions of mixing materials and crushing materials, and is an ideal device for producing non-fired bricks, lime-sand bricks, cement bricks, refractory bricks, crushing and mixing fly ash, boiler slag, tailings slag and industrial waste slag as raw materials for brick making. At present, when mixing materials, the sand mixer relies on a central planetary reducer to drive the stirring arm and the grinding wheel to rotate. Since both the stirring arm and the grinding wheel are fixedly connected to the turntable, and the stirring rod is also indirectly fixed on the turntable. During stirring, the stirring rod only rotates with the rotation of the turntable, and usually can only make the materials move in a circular motion in the horizontal plane. However, the full mixing of materials requires complex movements in multiple dimensions. This single-direction movement cannot make the materials fully exchange positions in different layers and directions, resulting in insufficient mixing and affecting the mixing effect of the sand mixer on the materials. Summary of the Invention

[0003] The purpose of the present invention is to provide an efficient planetary rotor sand mixer to solve the above deficiencies in the technology.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An efficient planetary rotor sand mixer, including a sand mixing frame, a feeding frame and a first servo motor. A maintenance window that opens and closes the top of the sand mixing frame is hinged to the top of the sand mixing frame, and a transmission column that cooperates with the first servo motor is installed inside the sand mixing frame;

[0005] The mixing component is used to divide the internal mixing part of the sand mixing rack into three mixing states, keep different contact angles with the materials, and promote the three-dimensional mixing of the materials inside the sand mixing rack. The mixing component includes a rotating frame sleeved at the bottom of the driving column, and a connecting column and a centering column respectively installed on both sides of the rotating frame. Three inclined rods are installed at the bottom of the connecting column, and an inclined bottom plate is installed at the bottom of the inclined rods. A connecting component for connection is arranged between the bottom plate and the inclined rods, and the connecting component is used to simultaneously adjust the distance and angle between the bottom plate between the inclined rods and the sand mixing rack. A support plate is installed on the top of the bottom plate, and the bottom plate and the support plate are used to radially push the materials. A side rod is screwed on one side of the rotating frame close to the connecting column, and the side rod is used to convectively push the materials between the materials and the centering column and scrape the inner wall of the sand mixing rack. A cooperative component for connection is arranged between the driving column and the connecting column, and the cooperative component is used to rotate the connecting column on one side of the rotating frame; and when the rotating frame rotates, it drives the side rod, the inclined rod, the support plate and the centering column to rotate. At this time, the side rod and the centering column are used to convectively push the materials, and the support plate and the inclined rod are used to radially push the materials inside the sand mixing rack, ensuring the three-dimensional mixing of the materials inside the sand mixing rack, which is beneficial to the full agitation of the materials inside the sand mixing rack. The simultaneous action of multiple regions can shorten the time required to reach uniformity. At the same time, it avoids the splashing of the materials during agitation, prevents the splashed materials from hitting the equipment sensors and adhering to the inner wall of the sand mixer, the transmission shaft or the observation window, and hardening to form stubborn dirt, reducing the cleaning difficulty of the sand mixing rack.

[0006] Preferably, a central ring frame is fixedly sleeved outside the centering column, and inclined stirring rods are installed outside the central ring frame. The top end of the rotating frame is fixedly connected with a second servo motor, and the second servo motor is used to drive the centering column to rotate; and the cooperation of the first servo motor and the second servo motor is used to drive the stirring rods, the inclined rods and the side rods to have different rotation speeds on the rotating frame. The direct connection of the second servo motor and the centering column can ensure that the stirring rods have a relatively high rotation speed to disperse the materials, and the relatively low rotation speeds of the side rods and the inclined rods are used to push the materials to circulate inside the sand mixing rack, so as to ensure the full contact and mixing of various materials and avoid the situation of uneven local mixing.

[0007] Preferably, the connection component includes a connection plug column fixedly connected to the top of the bottom plate and a connection seat fixedly sleeved on the bottom end of the inclined rod, and the connection seat and the connection plug column are used to keep the bottom plate and the inclined rod connected. A slot for inserting the connection plug column is formed at the bottom end of the connection seat, and the slot is of a convex structure. A limiting ring frame is fixedly connected inside the slot, and the limiting ring frame is sleeved outside the connection plug column. A first limiting plate is fixedly connected to the bottom end of the limiting ring frame, and a second limiting plate is fixedly connected to the bottom end of the first limiting plate. The first limiting plate and the second limiting plate are adjusted at the angle between the bottom end of the limiting ring frame and the outside of the connection plug column to ensure the stability of the connection plug column in the slot. The second limiting plate is arc-shaped and its bottom is recessed upward to form an inclined structure. A locking component for connection is arranged between the connection seat and the connection plug column; and under the action of the locking component, the second limiting plate and the first limiting plate tightly abut against the outside of the connection plug column to ensure the stability of the connection plug column in the slot. Moreover, the first limiting plate and the second limiting plate are made of flexible materials, aiming to have a pre-existing floating gap when the connection plug column is inserted into the slot, avoiding too tight insertion between the connection plug column and the slot, facilitating the free selection of the insertion height of the connection plug column in the slot, and enabling the connection plug column to rotate and adjust when inserted into the slot, increasing the flexibility of the device.

[0008] Preferably, the locking component includes a moving ring sleeved outside the connection plug column and an external thread ring frame fixedly connected to the bottom end of the connection seat.

A slope groove matched with the second limiting plate is formed inside the moving ring, and the slope groove is in slope fit with the bottom of the second limiting plate. A plurality of fitting grooves are formed on the outside of the connection plug column. A flexible pad matched with the fitting grooves is fixedly connected inside the second limiting plate, and the flexible pad tightly fits inside the fitting grooves; and with the cooperation of the locking component, it is ensured that the angle between the bottom plate and the inclined rod remains stable after adjustment, so that the inclination angle of the bottom plate and the support plate can be appropriately increased after adjustment, the shear force magnitude and direction applied by the support plate to the material can be changed, and the support plate can better drive the material to roll during rotation, enhancing the pushing and dispersing capabilities of the bottom plate and the support plate on the material.

[0009] Preferably, the cooperation component includes a cooperation frame installed inside the sand mixing machine frame and a third gear rotatably connected to one side of the rotating frame, and the third gear is used to drive the connecting column to rotate. A first gear is sleeved outside the transmission column. The middle of the bottom end of the cooperation frame is rotatably connected with a connecting frame. A toothed ring is fixedly connected to the bottom end of the connecting frame. One side of the cooperation frame is fixedly connected with a cooperation support, and the outside of the cooperation support is meshed with the third gear. A second gear meshing with the first gear and the toothed ring is installed at the bottom end of the cooperation support; teeth meshing with the second gear and the third gear are arranged on both the inside and outside of the toothed ring, and the cooperation component can drive the inclined rod, the bottom plate and the support plate to rotate along one side of the rotating frame, so that an asymmetric centrifugal force field is formed when the inclined support plate and the inclined rod rotate, enabling the material to periodically separate from the tank wall, thereby guiding the material to move in multiple directions inside the sand mixing machine frame, forming a more effective circulation, and improving the uniformity of the material mixing inside the sand mixing machine frame; in addition, the transmission column can be used for the simultaneous rotation of the rotating frame and the cooperation component, which can reduce unnecessary energy transmission, thereby improving the transmission efficiency of the equipment, reducing the time required for material mixing, improving the overall operation efficiency, and enhancing the flexibility of the device.

[0010] Preferably, a coordination component is further arranged between the support plate and the bottom plate, and the coordination component is used to adjust the height of the support plate on the bottom plate again. The coordination component includes a bolt screwed on one side of the support plate, a moving groove opened on one side of the bottom plate, and a threaded hole opened on one side of the support plate for the bolt to be screwed into. The bolt passes through the moving groove through the threaded hole. A threaded cap is screwed at one end of the bolt outside the moving groove. An elastic gasket is jointly connected between the threaded cap and the bottom plate, and the elastic gasket is sleeved outside the bolt; it can finely adjust the support plate and the bottom plate again after adjustment, reduce the frontal impact of the support plate on the bottom plate with the material, and disperse the material by the way of "pushing" rather than "cutting", enhancing the tumbling effect of the material.

[0011] Preferably, an inserting core plate is further installed on one side of the bottom plate close to the support plate. An inserting core groove for the inserting core plate to insert is opened on one side of the support plate. A guiding groove is opened on one side of the bottom plate close to the inserting core plate. Closing plates are installed on both the upper and lower sides of the inserting core plate. Two closing grooves for the two closing plates to move up and down are opened inside the guiding groove.

[0012] Preferably, a coordination column is further fixedly connected inside the guiding groove. A coordination plate is fixedly connected to one side of the inserting core plate, and the coordination plate is located inside the guiding groove and slidably sleeved outside the coordination column. Two springs are connected between the upper and lower sides of the coordination plate and the guiding groove, and the two springs are sleeved outside the coordination column.

[0013] In the above technical solution, the technical effects and advantages provided by the present invention:

[0014] 1. Through the setting of the mixing components, it is possible to achieve the convection and radial propulsion of the materials inside the sand mixing rack, ensuring that the materials are mixed in a three-dimensional manner inside the sand mixing rack, which is conducive to fully agitating the materials inside the sand mixing rack. The simultaneous action of multiple regions can shorten the required time for material mixing;

[0015] And through the side rods, diagonal rods, support plates, and centering columns, simultaneous action in multiple regions is achieved inside the sand mixing rack, effectively reducing the splashing of materials during agitation, preventing the splashed materials from hitting the equipment sensors and adhering to the inner wall of the sand mixer, the transmission shaft, or the observation window, and forming stubborn dirt after hardening, which is more time-saving and labor-saving to clean.

[0016] 2. Through the setting of the first servo motor, the second servo motor, the stirring rod, the diagonal rod, the side rod, and the rotating frame, it is possible to drive the stirring rod, the diagonal rod, and the side rod to have different rotation speeds on the rotating frame. The direct connection between the second servo motor and the centering column can ensure that the stirring rod has a relatively high rotation speed for dispersing the materials, and the relatively low rotation speeds of the side rod and the diagonal rod are used to push the materials to circulate inside the sand mixing rack, so as to ensure that various materials are fully contacted and mixed, avoiding the situation of uneven local mixing.

[0017] 3. Through the setting of the connection components, the diagonal rod, the bottom plate, and the support plate, it is possible to achieve a pre-existing floating gap when the connection plug column is inserted into the slot, avoiding the insertion between the connection plug column and the slot being too tight, facilitating the free selection of the height at which the connection plug column is inserted into the slot, and the connection plug column can also be adjusted by rotation when inserted into the slot, increasing the flexibility of the device.

[0018] 4. Through the setting of the locking components, the bottom plate, the connection plug column, and the slot, it is ensured that the angle between the bottom plate and the diagonal rod remains stable after adjustment, so that the bottom plate and the support plate can appropriately increase the inclination angle after adjustment, which can change the magnitude and direction of the shear force exerted by the support plate on the materials, enabling the support plate to better drive the materials to roll during rotation, and enhancing the pushing and dispersing capabilities of the bottom plate and the support plate on the materials.

[0019] 5. Through the setting of the cooperation components, the transmission column, the diagonal rod, the bottom plate, and the rotating frame, it is possible to drive the diagonal rod, the bottom plate, and the support plate to rotate along one side of the rotating frame, so that an asymmetric centrifugal force field is formed when the inclined support plate and the diagonal rod rotate, causing the materials to periodically break away from the tank wall, thereby guiding the materials to move in multiple directions inside the sand mixing rack, forming a more effective circulation, and improving the uniformity of material mixing inside the sand mixing rack.

[0020] 6. Through the setting of the coordination components, the connection components, the support plate, and the bottom plate, it is possible to fine-tune the support plate and the bottom plate again after adjustment, reducing the frontal impact of the inclination angle of the support plate on the bottom plate with the materials, and dispersing the materials by the method of "pushing" rather than "cutting", enhancing the rolling effect of the materials.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0044] II. The operator sets the required sand material weight and formula ratio on the control panel;

[0045] III. The system automatically weighs the empty weight of the sand mixer to ensure the accuracy of the zero point of the weighing sensor;

[0046] IV. The system opens the feeding valve and starts to add sand material into the sand mixer;

[0047] V. The weighing sensor monitors the sand material weight in the sand mixer in real time and transmits the data to the control system;

[0048] 6. The control system compares the real-time weight with the set weight;

[0049] 7. When the weight of the sand material approaches the set value, the system gradually reduces the opening degree of the feeding valve to slow down the feeding speed and prevent overfeeding;

[0050] 8. When the weight of the sand material reaches the set value, the system completely closes the feeding valve and stops feeding;

[0051] 9. The system reconfirms whether the weight of the sand material is accurate. If there is a deviation, fine-tuning is performed.

[0056] Through the above technical solutions:

[0057] When in use;

[0058] First step, when it is necessary to stir the material in multiple directions within the sand mixing frame 1, first, the first servo motor 11 drives the transmission column 14 to rotate inside the sand mixing frame 1. Immediately afterwards, the rotation of the transmission column 14 drives the rotation frame 21 to rotate simultaneously. At this time, the rotation of the rotation frame 21 drives the side rod 26, the inclined rod 23, and the stirring rod 28 to rotate simultaneously. Moreover, the side rod 26 rotates around the inner wall of the sand mixing frame 1 to stir the outermost circle of the material inside the sand mixing frame 1. And the second servo motor 201 is driven at this time to drive the centering column 29 to rotate. Through the rotation of the centering column 29, the central ring frame 27 and the stirring rod 28 rotate simultaneously, so that the stirring rod 28 can rotate on its own while the rotation frame 21 is rotating. And the rotation of the stirring rod 28 is used to stir the surrounding materials. And the side rod 26 pushes the materials stirred by the stirring rod 28, so that the side rod 26 and the stirring rod 28 realize convective pushing of the materials inside the sand mixing frame 1. As the transmission column 14 rotates, it drives the first gear 52 to rotate synchronously. Then, the rotation of the first gear 52 meshes with the second gear 54 and drives the second gear 54 to rotate on the cooperative support 53. At this time, the rotation of the second gear 54 meshes with the inner ring teeth of the tooth ring 56 to drive the tooth ring 56 and the connection frame 55 to move along the circumference at the bottom of the cooperative frame 51. Subsequently, when the tooth ring 56 rotates, its outer ring teeth on the outside mesh with the third gear 57 to drive the connection column 22 to rotate on one side of the rotation frame 21, so that the connection column 22 rotates on its own on one side of the rotation frame 21. Thus, the rotation of the connection column 22 drives the inclined rod 23, the bottom plate 24, and the support plate 25 to rotate simultaneously, so that an asymmetric centrifugal force field is formed when the inclined support plate 25 and the inclined rod 23 rotate, causing the material to periodically separate from the tank wall, and then ensuring that the material is mixed in a three-dimensional solid state inside the sand mixing frame 1, which is beneficial to fully stirring the material inside the sand mixing frame 1 and improving the uniformity of the material mixing inside the sand mixing frame 1.

[0059] Step 2: When it is necessary to adjust the height and angle of the bottom plate 24 between the diagonal rod 23 and the sand mixing machine frame 1, first rotate the moving ring 38 to drive the screwing together between the internally threaded ring frame 301 and the externally threaded ring frame 303, so that the internally threaded ring frame 301 rotates downward along the outside of the externally threaded ring frame 303. Immediately, the moving ring 38 moves downward along the bottom of the connecting seat 31 and drives the slope groove 39 to move downward along the outside of the second limiting plate 36 at the same time. At this time, the slope of the slope groove 39 and the second limiting plate 36 are matched and gradually lose contact, so that the release of the contact between the inside of the slope groove 39 and the outside of the second limiting plate 36 loses the resisting effect, and the second limiting plate 36 itself moves slowly and resets when losing the resistance. Moreover, the movement and reset of the second limiting plate 36 drive the flexible pad 37 to move at the same time, so that the flexible pad 37 slowly moves out of the inside of the fitting groove 302 under the movement. Thus, the second limiting plate 36 and the flexible pad 37 lose the locking effect on the connecting plug post 32 inside the slot 34 and the limiting ring frame 33. Then, there is a pre-existing floating gap when the connecting plug post 32 is inserted into the slot 34, avoiding the overly tight insertion between the connecting plug post 32 and the slot 34, facilitating the free selection of the height at which the connecting plug post 32 is inserted into the slot 34, and the connecting plug post 32 can also be adjusted by rotation when inserted into the slot 34.

[0060] Step 3: When it is necessary to adjust the support plate 25 on the bottom plate 24, rotate the threaded cap 45 to screw it along the outside of the bolt 41, so that the threaded cap 45 moves leftward along the bolt 41. And the threaded cap 45 loses the resisting effect on one side of the elastic gasket 44 when moving. Immediately, the bolt 41 becomes loose inside the moving groove 43. At this time, push the support plate 25 to move downward along one side of the bottom plate 24, and the plug core groove 47 generates resistance with the plug core plate 46 when the support plate 25 moves downward. Immediately, the plug core groove 47 drives the plug core plate 46 to move downward synchronously. Moreover, the downward movement of the plug core plate 46 drives the closing plate 401 to move downward inside the closing groove 49, and the downward movement of the plug core plate 46 drives the coordination plate 402 to move downward inside the guiding groove 48 at the same time. Thus, the coordination plate 402 moves downward along the outside of the coordination column 403 and squeezes one of the springs 404. Then, the support plate 25 and the bottom plate 24 can be finely adjusted again after adjustment, so that the inclination angle of the support plate 25 on the bottom plate 24 is reduced to resist the frontal impact of the material, and the material is dispersed by the "pushing" rather than "cutting" method, enhancing the material tumbling effect.
