Description

Technical Field

[0001] This utility model belongs to the field of white fused alumina production technology, specifically relating to a mixing device for white fused alumina production. Background Technology

[0002] In the production process of white fused alumina, different raw materials need to be mixed using a mixing device. The mixing device for white fused alumina production mainly consists of a machine body, a cylinder, and a stirring arm. The cylinder and stirring arm are installed on the machine body. Raw materials are added to the cylinder, and the stirring arm rotates inside the cylinder to agitate the raw materials and achieve the purpose of mixing.

[0003] In existing mixing devices for white fused alumina production, the cylinder is generally fixedly connected to the machine body during use, making the cylinder stationary relative to the machine body. Mixing is carried out only by the stirring arm rotating relative to the inner wall of the cylinder, resulting in insufficient mixing efficiency. Furthermore, when it is necessary to discharge the material after mixing, the cylinder, which is fixedly connected to the machine body, makes it inconvenient to remove the mixed material, resulting in insufficient discharge efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for white corundum production. The device can cause the cylinder to rotate in the opposite direction after the stirring arm rotates, so that the material is mixed in a countercurrent manner inside the cylinder, reducing local uneven mixing and improving mixing efficiency. The stirring arm can also be moved up and down along the cylinder to adjust the height of the stirring arm, so as to reduce the phenomenon of material stratification in the vertical direction and the resulting uneven mixing. Furthermore, the upward movement of the stirring arm causes the discharge plate to rotate downward, which facilitates the discharge of material in the cylinder along the inclined discharge plate.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A mixing device for white fused alumina production includes a body, a lifting arm slidably mounted on the body along a vertical direction, and a stirring arm rotatably mounted at the end of the lifting arm. The device also includes:

[0007] A mixing mechanism is provided at the lower end of a mixing arm. The mixing mechanism includes a discharge plate located below the mixing arm, which is slidably connected to the machine body in a vertical direction. The bottom of the discharge plate is fitted into the machine body. A shell is hinged to the discharge plate, and a cylinder is rotatably connected inside the shell. The cylinder is located outside the mixing arm, and the lower end of the cylinder is fitted into the top of the discharge plate. A first gear and a second gear are rotatably connected to the shell, and the first gear meshes with the second gear. A gear ring is fixedly connected to the cylinder, and the second gear meshes with the gear ring. The first gear is slidably connected to the mixing arm in a vertical direction. A stop block is provided below the first gear, and the stop block is fixedly connected to the mixing arm.

[0008] The stirring arm rotates and drives the cylinder to rotate in the opposite direction through the first gear, the second gear and the gear ring. The lifting arm moves up and drives the shell to move up through the stirring arm, which in turn causes the discharge plate to rotate downward.

[0009] The shell includes a lower shell plate disposed at the lower end of the stirring arm, one end of the discharge plate is hinged to the lower shell plate, a protruding flange is fixedly connected to the cylinder, the protruding flange is rotatably engaged with the lower shell plate, a retaining ring is disposed above the protruding flange, the retaining ring is fixedly connected to the lower shell plate, an upper shell plate is fixedly connected to the top of the retaining ring, and the first gear and the second gear are rotatably connected to the upper shell plate.

[0010] Several stirring plates are fixedly connected to the stirring arm, and several protruding plates are fixedly connected to the inner wall of the cylinder.

[0011] A baffle is fixedly connected to the machine body, and the baffle slides in a vertical direction with the discharge plate.

[0012] A slide bar is fixedly connected to the stirring arm, and a sliding groove is provided on the first gear. The slide bar and the sliding groove slide together in a vertical direction.

[0013] The lifting arm is slidably connected to the machine body in the vertical direction, and a telescopic cylinder is fixedly connected to the machine body. The output end of the telescopic cylinder is fixedly connected to the lifting arm.

[0014] A motor is fixedly connected to the end of the lifting arm, and the stirring arm is fixedly connected to the output end of the motor.

[0015] The technical effects achieved by this utility model are as follows:

[0016] The stirring arm of this invention rotates, causing the cylinder to rotate in the opposite direction, which makes the material flow and mix countercurrently inside the cylinder. Compared with the existing technology, which only uses a stirring arm that rotates relative to the inner wall of the cylinder for mixing, this reduces localized uneven mixing and improves mixing efficiency.

[0017] The stirring arm of this invention moves up and down along the cylinder to adjust the height of the stirring arm, reducing the stratification of materials in the vertical direction and thus preventing uneven mixing, thereby improving mixing efficiency. As the stirring arm continues to move upward, it drives the shell, cylinder and discharge plate to move upward through the stop block, causing the discharge plate to rotate downward. The material in the cylinder is discharged outward along the inclined discharge plate. Compared with the cylinder fixed to the machine body in the prior art, it is easier to remove the mixed material and improve the discharge efficiency. Attached Figure Description

Detailed Implementation

[0030] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0031] like Figures 1 to 10As shown, a mixing device for white fused alumina production includes a body 10, a lifting arm 11 slidably mounted on the body 10 along the vertical direction, and a stirring arm 12 rotatably mounted on the end of the lifting arm 11. It also includes a mixing mechanism 20, which is located at the lower end of the stirring arm 12. The mixing mechanism 20 includes a discharge plate 21 located below the stirring arm 12. The discharge plate 21 is slidably connected to the body 10 along the vertical direction, and the bottom of the discharge plate 21 fits snugly against the body 10. A housing 22 is hinged to the discharge plate 21. The internal rotating connection is a cylinder 23, which is located outside the stirring arm 12. The lower end of the cylinder 23 fits against the top of the discharge plate 21. A first gear 24 and a second gear 25 are rotatably connected to the shell 22. The first gear 24 and the second gear 25 mesh with each other. A gear ring 26 is fixedly connected to the cylinder 23. The second gear 25 meshes with the gear ring 26. The first gear 24 is slidably connected to the stirring arm 12 in the vertical direction. A stop block 27 is provided below the first gear 24 and is fixedly connected to the stirring arm 12.

[0032] It should be noted that the diameter of the baffle 27 is larger than that of the stirring arm 12. One end of the discharge plate 21 is rotatably connected to one end of the housing 22. The other end of the discharge plate 21 is integrally provided with a discharge port. In the initial state, the bottom of the discharge plate 21 is in contact with the machine body 10, the discharge plate 21 is in a horizontal state, the bottom of the cylinder 23 is in contact with the top of the discharge plate 21, and the baffle 27 is located below the first gear 24.

[0033] In this embodiment, the rotation of the stirring arm 12 drives the first gear 24 to rotate. The first gear 24, through the second gear 25, drives the gear ring 26 to rotate in the opposite direction. That is, the rotation direction of the first gear 24 is opposite to the rotation direction of the gear ring 26. The gear ring 26 drives the cylinder 23 to rotate, so that the rotation direction of the stirring arm 12 is opposite to the rotation direction of the cylinder 23. Compared with the prior art, where the cylinder 23 is fixed and the mixing is only carried out by the stirring arm 12 rotating relative to the inner wall of the cylinder 23, the material is mixed in a countercurrent manner inside the cylinder 23, reducing local uneven mixing and improving mixing efficiency. Furthermore, after the lifting arm 11 moves up and down along the machine body 10, it drives the stirring arm 12 to move up and down relative to the cylinder 23 and the shell 22, thereby adjusting the height position of the lower end of the stirring arm 12 in the cylinder 23. This adjusts the stirring height position of the stirring arm 12, reducing the phenomenon of material stratification in the vertical direction and causing uneven mixing, thus improving mixing efficiency. When discharge is required, the lifting arm 11 moves upward along the machine body 10, and the lifting arm 11 carries... The stirring arm 12 moves upward, causing the stop block 27 to contact the housing 22. The housing 22 prevents the stop block 27 from moving further upward. The stirring arm 12 continues to move upward, causing the stirring arm 12 to drive the housing 22, cylinder 23, and discharge plate 21 to move upward along the machine body 10 via the stop block 27. The vertical distance between the bottom of the cylinder 23 and the machine body 10 increases. Since the discharge plate 21 is rotatably connected to the housing 22, the end of the discharge plate 21 rotates downward. At this time, the discharge plate 21 tilts downward, and the cylinder 22... The material in section 3 falls downward from the lower end of the cylinder 23 onto the discharge plate 21. This material is discharged outward along the inclined discharge plate 21, thus achieving discharge. The greater the upward movement of the stirring arm 12, the greater the vertical distance between the cylinder 23 and the machine body 10, the greater the downward tilt angle of the discharge plate 21, and the greater the speed at which the material is discharged outward along the inclined discharge plate 21. Compared with the cylinder 23 fixedly connected to the machine body 10 in the prior art, it is easier to remove the mixed material and improve the discharge efficiency.

[0034] like Figure 4 , Figure 6 , Figure 9 and Figure 10 As shown, the shell 22 includes a lower shell plate 221 disposed at the lower end of the stirring arm 12, one end of the discharge plate 21 is hinged to the lower shell plate 221, a protruding flange 231 is fixedly connected to the cylinder 23, the protruding flange 231 is rotatably engaged with the lower shell plate 221, a retaining ring 222 is disposed above the protruding flange 231, the retaining ring 222 is fixedly connected to the lower shell plate 221, an upper shell plate 223 is fixedly connected to the top of the retaining ring 222, and a first gear 24 and a second gear 25 are rotatably connected to the upper shell plate 223.

[0035] It should be noted that a rotating groove is provided on the lower shell plate 221, which is rotatably engaged with the protruding edge 231. The inner diameter of the retaining ring 222 is larger than the outer diameter of the cylinder 23, and the inner diameter of the retaining ring 222 is smaller than the diameter of the protruding edge 231. The upper shell plate 223 and the retaining ring 222 are fixedly connected together by several support rods and bolts. The support rods and bolts are existing technologies and will not be described in detail here.

[0036] In this embodiment, the retaining ring 222 prevents the protruding edge 231 from moving upward and separating from the lower shell plate 221, making the rotation process of the protruding edge 231 and the lower shell plate 221 more stable, thereby making the rotation process of the cylinder 23 along the shell 22 more stable.

[0037] like Figure 4 , Figure 6 and Figure 7 As shown, several stirring plates 31 are fixedly connected to the stirring arm 12, and several protruding plates 32 are fixedly connected to the inner wall of the cylinder 23.

[0038] In this embodiment, after the stirring arm 12 and the cylinder 23 rotate in opposite directions, the stirring plate 31 and the convex plate 32 also rotate in opposite directions, which facilitates the countercurrent mixing of materials inside the cylinder 23, reduces local uneven mixing, and improves mixing efficiency.

[0039] like Figure 1 and Figure 2 As shown, a baffle 33 is fixedly connected to the machine body 10, and the baffle 33 slides in cooperation with the discharge plate 21 in the vertical direction.

[0040] In this embodiment, the baffle 33 cooperates with the discharge plate 21, making the process of the discharge plate 21, the shell 22 and the cylinder 23 moving up and down in the vertical direction more stable.

[0041] like Figure 5 and Figure 8 As shown, a slide bar 34 is fixedly connected to the stirring arm 12, and a groove 35 is provided on the first gear 24. The slide bar 34 and the groove 35 slide in a vertical direction.

[0042] In this embodiment, the slider 34 and the groove 35 cooperate to prevent relative rotation between the stirring arm 12 and the first gear 24, so that the stirring arm 12 can drive the first gear 24 to rotate after rotating, and also makes the process of the stirring arm 12 moving up and down along the first gear 24 more stable.

[0043] like Figure 1 , Figure 2 and Figure 7 As shown, the lifting arm 11 is slidably connected to the machine body 10 in the vertical direction, and a telescopic cylinder 36 is fixedly connected to the machine body 10. The output end of the telescopic cylinder 36 is fixedly connected to the lifting arm 11.

[0044] It should be noted that a sliding hole is provided on the body 10 along the vertical direction, and the sliding hole slides and engages with the lifting arm 11 along the vertical direction. In this utility model, the telescopic cylinder 36 is preferably a telescopic hydraulic cylinder.

[0045] In this embodiment, after the telescopic cylinder 36 is working, the output end drives the lifting arm 11 to move up and down along the machine body 10, which facilitates adjusting the height position of the lower end of the stirring arm 12 in the cylinder 23, so as to adjust the stirring height position of the stirring arm 12. It also facilitates the upward movement of the shell 22, cylinder 23 and discharge plate 21 along the machine body 10 through the stirring arm 12 and the stop block 27, so as to remove the mixed material.

[0046] like Figure 1 , Figure 2 and Figure 7 As shown, a motor 37 is fixedly connected to the end of the lifting arm 11, and the stirring arm 12 is fixedly connected to the output end of the motor 37.

[0047] In this embodiment, after the motor 37 is working, the output end drives the stirring arm 12 to rotate, which facilitates the driving of the stirring arm 12 to rotate inside the cylinder 23. Since the motor 37 drives the stirring arm 12 to rotate while also causing the cylinder 23 to rotate in the opposite direction, the reverse rotation of the stirring arm 12 and the cylinder 23 only requires the motor 37 as a driving source, reducing the number of driving sources.

[0048] The working principle of this utility model is as follows: During mixing, the stirring arm 12 rotates and drives the cylinder 23 to rotate in the opposite direction through the first gear 24, the second gear 25 and the gear ring 26, so that the material is mixed evenly in the cylinder 23, improving the mixing efficiency. After the stirring arm 12 moves up and down, it is easy to adjust the stirring position of the lower end of the stirring arm 12 inside the cylinder 23, improving the mixing efficiency. It is also easy to drive the shell 22, the cylinder 23 and the discharge plate 21 to move upward, so that the discharge plate 21 rotates downward, and the material inside the cylinder 23 is discharged outward along the inclined discharge plate 21, improving the discharge efficiency.

[0049] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
