When in use, the raw materials are loaded into the feeding hopper, and then the first motor is started. The first motor drives the screw to rotate, and the feeding screw drives the raw materials to move along the feeding tube when it rotates, so that the raw materials are transported into the vertical casing. This application has the effect of being able to facilitate the feeding of materials into the dryer, but similar to the vertical mixer in the above-mentioned document, when the raw materials are mixed during operation, the raw materials may be agglomerated. At the same time, after the mixing is completed, the agglomerated raw materials and the mixed raw materials will be output simultaneously, so that other applicable equipment is required for screening later.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a vertical mixer is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a vertical mixer to solve the problems raised in the above background technology.

[0007] Furthermore, the driving structure includes an AC motor, a transmission structure and a coupling. The bottom power output end of the AC motor is connected to the transmission structure, and the coupling is vertically installed in the middle of one end of the transmission structure away from the AC motor.

[0008] Furthermore, the coupling extends to the inner top of the mixing barrel, and the bottom end of the coupling is flange-connected to the top end of the agitator.

[0009] Furthermore, the agitator includes a screw, a spiral arm, a spiral ribbon and an antistatic coating.

[0014] The utility model provides a vertical mixer, which has the following beneficial effects:

[0015] 1. The utility model has a screen installed at one end of the discharge pipe and cooperates with the use of a vibration motor at the lower end of the outside of the mixing barrel. When the vibration motor is running, the vibration generated by it will be transmitted to the inside of the entire mixing barrel. At this time, the mixed material will pass through the screen at one end of the discharge pipe when it is discharged to the outside through the discharge pipe. At this time, the vibration generated by the operation of the vibration motor will also act on the screen at the same time. By using the above structure, the output powder can be quickly screened to the greatest extent, and the output of agglomerated powder can be prevented, thereby ensuring the quality of the output mixed powder. After that, the screened block material can be taken out and reprocessed by using the cleaning valve pipe. In addition, by using the above structure, the rotating agitator can transmit the powder from bottom to top, while the powder in the upper layer is deposited downward as much as possible under the action of vibration. By using the reverse drive of the agitator, the sufficiency of the mixed powder can be further guaranteed, and the upper layer powder can be prevented from gathering on the upper part of the mixing barrel and unable to be mixed with the lower layer powder.

[0016] 2. The utility model, through the use of the agitator, when the driving structure drives the entire agitator to rotate vertically inside the mixing barrel, the rotating screw at this time will make the powder upper body at the center of the entire mixing barrel, and at the same time, the side spiral arm will drive the spiral belt connected thereto to revolve around the screw, so that the powder outside the screw enters the stud to different degrees, thereby achieving continuous mutual diffusion of materials in all circumferential directions, and the two streams of materials lifted to the upper part merge into the central concave cavity to form a downward material flow, which fills the vacancy at the bottom, thereby forming a triple mixing effect of convection circulation, and the vibration generated by the operation of the vibration motor makes the floating powder deposit downward under the vibration, thereby generating a plurality of mixing operations in different directions, and utilizing the mutual cooperation of the above structures to maximize the mixing effect, and at the same time, the anti-static coating sprayed on the entire agitator surface and the inner wall surface of the mixing barrel can avoid the powder from generating static electricity when rubbing against the rotating agitator surface as much as possible, thereby preventing the generated static electricity from causing the powder to generate problems such as agglomeration during the mixing process, thereby further ensuring the adequacy of the mixed powder.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 3As shown, a vertical mixer includes a mixing barrel 1 and a discharging structure 5, a driving structure 2 is installed on the top of the mixing barrel 1, and a feeding valve pipe 3 is arranged on one side of the driving structure 2, an agitator 4 is arranged inside the mixing barrel 1, the discharging structure 5 is arranged on one side of the lower end of the mixing barrel 1, and a vibration motor 6 is installed on the outer lower end of the mixing barrel 1, the discharging structure 5 includes a discharging pipe 501, a discharging valve 502 and a screen 503, one end of the discharging pipe 501 is connected to the discharging valve 502, and the screen 503 is installed inside the end of the discharging pipe 501 away from the discharging valve 502, the screen 503 is arranged inside the mixing barrel 1, and the discharging pipe 501 and the screen 503 are connected to each other. The nets 503 are movably connected, the vibration motor 6 is fixedly installed on both sides of the outside of the mixing barrel 1, and the discharge structure 5 is arranged above the vibration motor 6. A cleaning valve pipe 7 is installed at the bottom of the mixing barrel 1, and a supporting stand 8 is arranged in a circular array around the mixing barrel 1 with the mixing barrel 1 itself as the center. When the vibration motor 6 is operating, the vibration it generates will be transmitted to the interior of the entire mixing barrel 1. At this time, the mixed material will pass through the screen 503 at one end of the discharge pipe 501 when it is discharged to the outside through the discharge pipe 501. At this time, the vibration generated by the operation of the vibration motor 6 will also act on the screen 503 at the same time, thereby sieving the agglomerated powder.

[0023] like Figures 1 to 3 As shown, the driving structure 2 includes an AC motor 201, a transmission structure 202 and a coupling 203. The bottom power output end of the AC motor 201 is connected to the transmission structure 202, and the coupling 203 is vertically installed in the middle of one end of the transmission structure 202 away from the AC motor 201. The coupling 203 extends to the inner top of the mixing barrel 1, and the bottom end of the coupling 203 is flange-connected to the top of the agitator 4. The agitator 4 includes a screw 401, a spiral arm 402, a spiral ribbon 403 and an antistatic coating 404. The spiral arm 402 is arranged around the screw 401, and the spiral arm 402 is connected to the spiral ribbon 403 at one end away from the screw 401, and the surfaces of the spiral ribbon 403, the spiral arm 402 and the screw 401 are sprayed with the antistatic coating 404. The spiral arm 402 is centered on the screw 401 and extends from top to bottom. The spiral distribution below, and the screw 401, the spiral arm 402 and the spiral belt 403 are welded to each other, the inner wall surface of the mixing barrel 1 is sprayed with an anti-static coating 404, the rotating screw 401 will make the powder upper body at the center of the entire mixing barrel 1, and at the same time the side spiral arm 402 will drive the spiral belt 403 connected thereto to revolve around the screw 401, so that the powder outside the screw 401 enters the stud to varying degrees, thereby achieving continuous mutual diffusion of materials in all circumferential directions, and the two streams of materials lifted to the upper part merge into the central concave hole to form a downward material flow, which fills the vacancy at the bottom, thereby forming a triple mixing effect of convection circulation, and the vibration generated by the operation of the vibration motor 6 makes the floating powder settle downward under the vibration, thereby producing multiple mixing operations in different directions.

[0024] In summary, if Figures 1 to 3 As shown, when the vertical mixer is used, the powder materials to be mixed are first fed into the mixing barrel 1 in sequence through the feed valve pipe 3. When the powder materials are fed, the driving structure 2 is started. Under the operation of the AC motor 201, the transmission structure 202 drives the coupling 203 to rotate axially in the vertical direction. At this time, the agitator 4 connected to the bottom end of the coupling 203 will rotate synchronously inside the mixing barrel 1.

[0025] As the stirrer 4 rotates, the vibration motor 6 will operate synchronously. Under the action of the vertical axial rotation of the screw 401, the powder near the center of the mixing barrel 1 will gradually rise from the bottom of the mixing barrel 1 to the top. As the screw 401 rotates, the spiral belt 403 connected to the periphery of the screw 401 by the spiral arm 402 will perform an orbital motion with the spiral arm 402 as the center of the circle. As the spiral belt 403 of the spiral structure rotates and the rotary disturbance of the spiral arm 402, the powder near the inner wall of the mixing barrel 1 will flow near the screw 401 to varying degrees, thereby achieving continuous renewal and diffusion of the material in the entire circumference. Since the screw 401, the spiral arm 402 and the spiral belt 403 will lift the powder from bottom to top in different directions, the powder lifted to the upper part will converge at the central concave hole to form a downward material flow.

[0026] At the same time, the vibration generated by the operation of the vibration motor 6 will cause the powder to deposit as much as possible toward the bottom side of the inverted cone-shaped mixing barrel 1, forming a downward material flow, filling the vacancy at the bottom, thereby forming a multiple mixing effect of convection circulation. When the mixed powder enters the inside of the discharge pipe 501, with the assistance of the vibration generated by the operation of the vibration motor 6, the powder that is about to pass through the discharge valve 502 is sieved by the screen 503 to separate the agglomerated materials, and then the sieved materials can be taken out by opening the cleaning valve pipe 7 for further treatment.

[0027] The working principle of the vertical mixer is that the two asymmetric spirals in the mixer barrel rotate to lift the material upward, and the rotating arm revolves slowly; the material outside the spiral enters the stud to varying degrees, thereby achieving continuous renewal and diffusion of the material in the entire circumference. The two streams of material lifted to the upper part merge into the central concave hole to form a downward material flow, which fills the vacancy at the bottom, thus forming a triple mixing effect of convection circulation.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
