Description

Technical Field

[0001] The invention relates to the field of mixers, in particular to an automatic vertical mixer. Background Art

[0002] A mixer is an industrial equipment that mixes different types of raw materials together to form a solid homogenized mixture. The mixer can not only improve production efficiency, but also make the quality of the mixed product more stable and reliable to meet specific use requirements. At present, most existing mixers are placed horizontally. During the mixing process, the material moves horizontally from left to right as the blades rotate. The material is passively mixed between the container wall and the material and the blades. Therefore, the friction between the material and the container wall, the material and the blades, and the material and the material is relatively large. The friction of the material not only easily causes the horizontal container wall to wear and damage, but also the motor torque used for the rotation of the blades is large, which increases the motor power and energy consumption cost of the mixer. Due to the influence of gravity, the material is usually accumulated at the bottom of the horizontal container of the mixer for stirring and moving. There is a gap between the blades and the container wall. The stirring efficiency of the material near the horizontal container wall is not high, resulting in an insignificant effect on the uniformity of the material stirring. In addition, the output of the mixer is linearly related to the capacity, that is, the greater the material mixing output, the larger the volume structure of the horizontal container required, so the space occupied by the horizontal container of the mixer will become larger.

[0003] To this end, the present invention proposes an automatic vertical mixer to solve the problems that a traditional mixer takes up a large space when placed horizontally and materials accumulate and move horizontally in the container wall, causing wear of the container wall and uneven mixing of materials.

[0031] In the embodiment of the present disclosure, a feed slot that runs through from top to bottom is provided on the upper side surface of the feed shell 403 near the rear end, and a small slot that runs through from front to back is provided on the inner side wall of the feed slot of the feed shell 403. A push frame 410 is embedded in the small slot of the feed shell 403. The push frame 410 extends out from the small slot of the feed shell 403 to push the flap 406, so that the flap 406 flips up and down in the feed slot of the feed shell 403, thereby changing the passing size of the material in the feed slot of the feed shell 403. A rectangular slot is provided on the left side surface of the feed shell 403, and a flap door 405 is hinged inside the rectangular slot of the feed shell 403. The flap door 405 and the small slot on the inner side wall of the feed slot of the feed shell 403 are opposite to each other front to back, and the rectangular slot of the feed shell 403 is opposite to the control machine 413 left to right. By flipping open the flap door 405, it is convenient for maintenance personnel to maintain the control machine 413 inside the feed shell 403.

[0032] In the disclosed embodiment, there are two groups of push racks 410, which are symmetrically distributed on the left and right. The front side surfaces of each group of push racks 410 are inclined structures. The push racks 410 are provided with through holes that pass through the front and back. The guide support rods 415 are inserted into the through holes of the push racks 410, and the lower side surfaces of the push racks 410 are attached to the bottom side surfaces inside the feed shell 403, so that the push racks 410 can move forward or backward in a directional manner along the guide support rods 415 in the small through grooves of the feed shell 403, so that the two groups of push racks 410 push the flap 406 to flip stably.

[0033] In the disclosed embodiment, a threaded through hole is provided at the center of the pressure plate 409, and the outer side surface of the threaded rod 408 is threadedly engaged with the threaded through hole of the pressure plate 409. Through holes are provided on the upper side surface of the pressure plate 409 near the left end and the right end. Two groups of columns 411 are respectively inserted into the through holes of the pressure plate 409. In the process of the feed amount adjustment motor 407 driving the threaded rod 408 to rotate, the threaded rod 408 drives the pressure plate 409 engaged on the outer side surface to move vertically upward or downward along the column 411, so that the pressure plate 409 squeezes the inclined structure of the push frame 410, and completes the push frame 410 to flip and push the flap 406, and the flap 406 blocks the feed slot of the feed shell 403. The flap 406 changes the size of the feed slot of the feed shell 403 to control the feed amount of the vertical mixing device 4.

[0034] In the disclosed embodiment, the throwing shell 402 is a cylindrical structure that passes through from top to bottom. The rear side surface inside the cylindrical structure of the throwing shell 402 is a slope structure, and the slope is inclined at an angle of 45 degrees. The slope structure of the throwing shell 402 is opposite to the feed groove of the feed shell 403 from top to bottom. The material flowing into the feed groove of the feed shell 403 falls on the slope of the throwing shell 402. The material is scattered along the slope structure of the throwing shell 402 to the opening position at the bottom of the cylinder of the throwing shell 402 in a parabolic trajectory to the fan disk 416 by gravity, ensuring that the material is in contact with the fan disk 416.

[0035] In the disclosed embodiment, there are fifteen groups of blade fan disks 416, which are evenly arranged from top to bottom on the outer side of the mixing rotating rod 412. When the material falls downward in the mixing barrel 401, it passes through the fifteen groups of blade fan disks 416 in sequence, and the blade fan disks 416 evenly break up the vertically falling material.

[0036] In the disclosed embodiment, the mixing barrel 401 has a J-shaped barrel structure that runs through the top and bottom, and a 60-degree discharge bevel is provided at the bottom end of the J-shaped structure of the mixing barrel 401. Fifteen groups of blade fan disks 416 are evenly arranged inside the barrel structure of the mixing barrel 401. The materials dispersed by the blade fan disks 416 fall toward the 60-degree discharge bevel at the bottom end of the mixing barrel 401 by gravity, allowing the vertically falling materials to slide out evenly along the 60-degree discharge bevel, thereby preventing the dispersed materials from accumulating and remaining in the mixing barrel 401.

[0037] In the embodiment of the present disclosure, there are two groups of springs 414, the front end of the spring 414 is fixedly connected to the push rack 410, and the rear end of the spring 414 is fixedly connected to the feed shell 403. The spring 414 elastically supports the push rack 410 and the feed shell 403 through elastic force. In the process of the pressure plate 409 being lifted upward along the column 411, the spring 414 pushes the push rack 410 to move backward along the guide support rod 415, so that the push rack 410 is separated from the flap 406, and the flap 406 flips downward by gravity, reducing the blocking surface of the flap 406 on the feed slot of the feed shell 403, thereby increasing the feed flow rate of the feed slot of the feed shell 403.

[0038] The specific usage and function of this embodiment are as follows: When the vertical mixing device 4 of the present invention is performing the material dispersing and mixing work, the control panel 5 inputs the mixing control command, and the control panel 5 sends the mixing control command to the control machine 413 through the wire. The control machine 413 controls the stirring and mixing motor 404 to start through the wire, and the stirring and mixing motor 404 drives the mixing rotating rod 412 to rotate, and the mixing rotating rod 412 drives the fifteen sets of blade fan disks 416 welded and connected on the outer side to rotate synchronously, and then pours the material into the feeding slot of the feeding shell 403, and the material passes through the feeding slot of the feeding shell 403 by gravity and falls to the 45-degree inclined surface structure of the throwing shell 402, and the material slides forward along the 45-degree inclined surface structure of the throwing shell 402, so that the material relies on The material falls along a parabolic path toward the blade fan disk 416 inside the mixing barrel 401, ensuring that the material contacts and collides with the blade fan disk 416. In the process of the material falling downward in the mixing barrel 401 under the force of gravity, the fifteen groups of rotating blade fan disks 416 evenly stir, impact and scatter the material, which not only fully mixes the material in the process of falling in the mixing barrel 401, but also avoids the contact and friction between the material and the inner wall of the mixing barrel 401. The scattered and mixed material falls to the 60-degree oblique portion of the mixing barrel 401, and the material evenly slides out of the mixing barrel 401 along the 60-degree inclined direction of the mixing barrel 401, thereby completing the material scattering and mixing work of the vertical mixing device 4. If it is necessary to adjust the feed flow of the vertical mixing device 4 The control panel 5 inputs the feed flow control command, and the control panel 5 sends the feed flow control command to the control machine 413 through the wire. The control machine 413 controls the feed amount adjustment motor 407 to start through the wire, and the feed amount adjustment motor 407 drives the threaded rod 408 to rotate. Since the outer side of the threaded rod 408 is threadedly engaged and connected in the threaded through hole of the pressure plate 409, the threaded rod 408 drives the pressure plate 409 to move downward or upward along the column 411. If it is necessary to reduce the feed flow, the pressure plate 409 pushes the inclined structure of the push frame 410 downward, so that the push frame 410 moves backward along the guide support rod 415 to overcome the elastic force of the spring 414, and the rear end of the push frame 410 extends out of the feed. The rear end of the push frame 410 pushes the flap 406 to flip upward in the feed slot of the feed shell 403, thereby increasing the flap 406 blocking area of ​​the feed slot of the feed shell 403 and reducing the material flow rate of the feed slot of the feed shell 403. If the feed flow rate needs to be increased, the pressure plate 409 is separated from the inclined structure of the push frame 410 upward, and the push frame 410 moves forward along the guide support rod 415 under the elastic force of the spring 414, and the rear end of the push frame 410 is separated from the flap 406, and the flap 406 flips downward due to gravity, thereby reducing the flap 406 blocking area of ​​the feed slot of the feed shell 403 and increasing the material flow rate of the feed slot of the feed shell 403.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
