Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this invention. The specific implementation scheme of this invention is as follows: A vertical material mixer includes a tank 1. A first stirring blade 2 and a second stirring blade 6 are rotatably mounted inside the tank 1. The second stirring blade 6 is located below the first stirring blade 2 and rotates in the opposite direction to the first stirring blade 2. The tank 1 is equipped with a rotating power component A3 and a rotating power component B7. The rotating power component A3 drives the first stirring blade 2 to rotate, and the rotating power component B7 drives the second stirring blade 6 to rotate. A secondary stirring blade 4 is rotatably mounted at the distal end of the first stirring blade 2. The first stirring blade 2 is equipped with a rotating power component C5 for driving the secondary stirring blade 4 to rotate. The independently rotating secondary stirring blade 4 can fully mix the material in the edge area of the tank 1. To prevent material from accumulating against the walls, the second stirring paddle 6 is arranged in a cross shape. The four free ends of the second stirring paddle 6 are connected to inclined plates A8 and B9 respectively. The distance between inclined plate A8 and the output shaft of the rotating power component B7 is greater than the distance between inclined plate B9 and the output shaft of the rotating power component B7. Inclined plates A8 and B9 tumble the bottom material upwards and participate in the stirring of the first stirring paddle 2 and the auxiliary stirring paddle 4, improving the overall uniformity of the material stirring. At the same time, the first stirring paddle 2 and the second stirring paddle 6, which rotate in opposite directions, can also disrupt the movement pattern of the material in the tank, enhance the collision and mixing effect between materials, further improve the stirring efficiency, and shorten the overall stirring operation time.
[0017] It should be noted that the upper part of the tank body 1 is designed with an open structure to facilitate the feeding of materials. The side wall of the tank body 1 has a discharge port, and a sealing door 10 is provided on the side wall of the tank body 1 outside the discharge port by means of a sliding mechanism. The sealing door 10 is connected to the tank body 1 by a telescopic power component 11 to facilitate unloading.
[0018] Specifically, vertical slide rails 12 are fixedly installed on the outer walls of the tank body 1 on both sides of the discharge port. The vertical slide rails 12 are slidably connected to the sealing door 10, which can provide stable guidance for the lifting and moving of the sealing door, avoid jamming and skew during the movement of the sealing door, and ensure the stable sealing effect of the sealing door on the discharge port. The telescopic power component 11 is a hydraulic cylinder. The two ends of the hydraulic cylinder are respectively hinged to the sealing door 10 and the tank body 1. By driving the sealing door 10 to slide up and down along the side wall of the tank body through the hydraulic cylinder 11, the opening and closing of the discharge port can be controlled. After the mixing is completed, the sealing door can be opened to discharge the material. The operation is simple and efficient, and there is no need for manual unloading, which reduces the labor intensity of the operators.
[0019] It should be noted that a fixed shell A13 and a connecting beam 14 are provided at the upper opening of the tank body 1. The fixed shell A13 is fixedly connected to the tank body 1 through the connecting beam 14. The rotating power component A3 is fixedly installed inside the fixed shell A13. The first stirring paddle 2 includes a rotating cover A21 fixedly connected to the output end of the rotating power component A3. The rotating cover A21 is rotatably fitted outside the fixed shell A13. The fixed shell A13 and the rotating cover A21 form a relatively sealed structure, which can reduce the entry of external dust or materials into the interior and contaminate the rotating power component A, thus extending the service life of the equipment.
[0020] A first crossbeam 22 and a second crossbeam 23 are sequentially fixed on the outer wall of the rotating cover A21 on one side of the fixed shell A13. The first crossbeam 22 and the second crossbeam 23 are arranged in a cross shape. A fixed shell C15 is fixedly installed at the end of the first crossbeam 22. The rotating power component C5 is fixedly installed inside the fixed shell C15. The auxiliary stirring paddle 4 includes a rotating cover C41 fixedly connected to the output end of the rotating power component C5. The rotating cover C41 is rotated and fitted outside the fixed shell C15, which can protect the rotating power component C5 and reduce the erosion of it by materials. Several evenly spaced vertical stirring columns 42 are fixedly installed outside the rotating cover C41. The stirring columns 42 rotate with the rotating cover C41 and rotate on their own axis while following the revolution of the first stirring paddle 2. They can stir the materials near the side wall of the tank 1 and the materials turned up by the inclined plates A8 and B9.
[0021] It should be noted that a U-shaped frame 18 is fixedly installed vertically at the lower part of the second crossbeam 23, and a fixing plate 19 is fixedly installed vertically inside the U-shaped frame 18. When the U-shaped frame 18 and the fixing plate 19 rotate with the first stirring paddle 2, they can stir the material in the tank 1 and further improve the overall stirring uniformity.
[0022] A fixed shell B17 is fixedly installed on the bottom inner side of the tank body 1. The fixed shell B17 is fixedly connected to the rotating power component B7. The output axis of the rotating power component B7 extends upward into the tank body 1 and is connected to the connecting plate 16 by a key. The connecting plate 16 is fixedly connected to the second stirring paddle 6. The fixed shell B17 can protect the rotating power component B7 located at the bottom of the tank body, preventing moisture or sand in the material at the bottom of the tank from corroding the rotating power component B7 and ensuring the stable operation of the drive structure.
[0023] Specifically, in this embodiment, the rotating power components A3, B7, and C5 are hydraulic motors, but in other embodiments they can also be electric motors.
[0024] In addition, sealing rings are provided between the output shaft of the rotating power component B7 and the fixed housing B17, between the rotating cover A21 and the fixed housing A13, and between the rotating cover C41 and the fixed housing C15. These can further improve the sealing performance of each rotating connection position, prevent material from seeping in, ensure the stable operation of each power component, and extend the equipment maintenance cycle and service life.
[0025] It should be noted that a bearing is fixedly installed at the lower part of the rotating cover A21. The bearing is sleeved outside the output shaft of the hydraulic motor 7. It can provide radial support to the rotating cover A21 without hindering the rotation of the second stirring paddle 2, thereby improving the stability of the first stirring paddle 2 and the second stirring paddle 6 during rotation and reducing swaying and deviation during rotation.
[0026] The working principle and process of this invention are as follows: All materials to be mixed are put into tank 1, and the rotating power components A3, B7 and C5 are started. Rotating power component A3 drives the first crossbeam 22 and the second crossbeam 23 to rotate through the rotating cover A21; rotating power component C5 drives the rotating cover C41 to drive the stirring column 42 to rotate; rotating power component B7 drives the second stirring paddle 6 to rotate through the connecting plate 16. The second stirring paddle 6 drives the inclined plate A8 and inclined plate B9 to continuously turn the sand and gravel deposited at the bottom of the tank upward and send the bottom material into the upper stirring area to participate in the mixing.
[0027] After mixing is completed, the hydraulic cylinder 11 is started, and the sealing door 10 is pulled to move upward along the vertical slide 12. The discharge port is opened, and the first stirring paddle 2, the auxiliary stirring paddle 4 and the second stirring paddle 6 continue to rotate. The uniformly mixed material continuously flows out of the discharge port. After the discharge operation is completed, the telescopic power component 11 pushes the sealing door 10 to reset and close the discharge port, and the next round of mixing operation can be carried out.
