DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Embodiment 1:

[0034] like Figures 1 to 10 As shown, a one-dimensional mixer system includes a one-dimensional mixer 106 provided with a feed port and a discharge port, and a reverse guide plate 117 and a forward guide plate 122 are installed on the wall of the inner cavity of the one-dimensional mixer 106, and the center of mass of the reverse guide plate 117 and the forward guide plate 122 are respectively distributed in a spiral along the rotation axis of the one-dimensional mixer 106, and the directions of the two spirals are opposite.

[0035] The forward guide plate 122 includes a discharge guide plate 120 disposed near the discharge port of the inner cavity of the one-dimensional mixer 106 .

[0036] The forward guide plate 122 includes a long guide plate 118 and a short guide plate 119. The long guide plate 118 and the short guide plate 119 are staggered along the circumferential direction on the inner wall of the one-dimensional mixer 106. The long guide plate 118 is installed on the one-dimensional mixer 106 along the rotation direction of the spiral line, and the short guide plate 119 is parallel to the axis of the one-dimensional mixer 106.

[0037] A triangular baffle is provided on the bent portion of the first set of long guide plates 118, and the discharge guide plate 120 is bent. The long guide plates 118 push the material to move clockwise and guide the material toward the discharge port. The short guide plates 118 cut off the material, causing part of the material to move up and down to increase uniformity. The reverse guide plates 117 reduce the accumulation of material at the tail of the one-dimensional mixer.

[0038] The reverse guide plate 117, the long guide plate 118, and the short guide plate 119 all include an extension portion and a bending portion, one side of the extension portion is connected to the inner cavity wall of the one-dimensional mixer 106, and the other side is bent to form a bending portion; the extension portion of a single long guide plate 118 is larger than the extension portion of a single short guide plate 119.

[0039] There is an acute angle between the extension part and the bending part of the positive guide plate and the reverse guide plate.

[0040] One or more of the long guide plates 118 distributed in the same spiral form a group. The multiple groups of long guide plates 118 are evenly distributed along the circumferential direction on the inner wall of the one-dimensional mixer 106 , and the short guide plates 119 are arranged between two adjacent groups of long guide plates 118 .

[0041] The forward guide plate 122 is installed on the inner wall of the one-dimensional mixer 106 to form a spiral angle of 40°-50°.

[0042] In this embodiment, the feed port is set at the tail of the one-dimensional mixer 106. After the inner cavity of the one-dimensional mixer 106 is evacuated to a negative pressure state by a vacuum pump, the feed valve 107 on the one-dimensional mixer 106 is opened, and the material is sucked from the feed port. Then, the feed valve 107 is closed and the one-dimensional mixer 106 is started.

[0043] like Figure 6 As shown, the reverse guide plate 117, the long guide plate 118, the short guide plate 119 and the conveying guide plate 121 are arranged alternately in a spiral on the one-dimensional mixer, and the reverse guide plate 117, the long guide plate 118 and the conveying guide plate 121 are arranged obliquely along the spiral line, and the inclination angle is 40° to 50°, so that the material can be conveyed to move left and right, and the short guide plate 119 is placed horizontally, so that the short guide plate 119 can only drive the material to move from a low place to a high place and then fall, and cannot drive the material to be conveyed left and right.

[0044] like Figure 6 As shown, the conveying guide plate 121 and the reverse guide plate 117 have opposite spiral directions. When the material is placed at the position of the directional guide plate 117, when the one-dimensional mixer 106 rotates forward, the extension and the bending part of the reverse guide plate 117 push the material to move spirally to the high right side, that is, the upper end of the long guide plate 118. Then the material falls from the reverse guide plate due to gravity and falls into the one-dimensional mixer. When the mixer continues to rotate, the long guide plate 118 drives this part of the material to move spirally to the left. , moves to the high place on the left, that is, the position of the reverse guide plate 117 and the conveying guide plate 121, and then the material is conveyed to the left end of the one-dimensional mixer through the conveying guide plate 121, and the material moves from the low place of the one-dimensional mixer 106 to the high place, and then falls, and then is conveyed to the right through the reverse guide plate 117, and then through the cooperation of the reverse guide plate 117, the long guide plate 118 and the conveying guide plate 121, the material performs left and right spiral reciprocating motion, thereby improving the mixing effect and efficiency of the material.

[0045] After the mixing is completed, when the material needs to be output, the one-dimensional mixer is controlled to rotate in the opposite direction, thereby changing the spiral rotation direction of the reverse guide plate 117, the long guide plate 118 and the conveying guide plate 121, so that the reverse guide plate 117 pushes the material to move to the left, and drives the material to move from a low place to a high place, and then falls, and the material is transported to the long guide plate 118 through the conveying guide plate 121, and then the material is transported to the right by multiple long guide plates 118. During the transportation of the long guide plate 118, the triangular baffle will block the material from being transported to the right, that is, the material moves to the extension and bending part of the long guide plate 118, and then follows the long guide plate 118 to move from a low place to a high place and fall to the right of the triangular baffle, and then the material is transported to the right by the long guide plate 118 provided with the triangular baffle. During this period, the material is also driven by the short guide plate 119 to move from a low place to a high place and fall, and the material will not be transported to the right, and the short guide plate 119 makes the material more uniform.

[0046] like Figure 3 and Fig.10 As shown, the discharge guide plate 120 at the discharge port of the one-dimensional mixer 106 is provided with a bending angle compared with the prior art, and the bending range is 160°-170°.

[0047] The space between the end of the discharge guide plate 120 away from the discharge port of the one-dimensional mixer 106 and the inner cavity of the one-dimensional mixer 106 becomes larger, that is, after bending, the discharge guide plate 120 can receive more materials in the same time, and the bending angle is more in line with the trajectory of the material rotation, reducing the resistance of the material flowing out of the discharge port, thereby accelerating the outflow of the material in the one-dimensional mixer 106 and improving the material output speed. In actual production, it takes 3.5 hours to discharge 2 tons of material, and it takes 40 minutes to discharge 2 tons of material after improvement.

[0048] After the materials are mixed, they are transported to the receiving hopper 109 through the guide hopper 108. The materials are in powder form. Because dust is generated during mixing, if the dust is not processed, the dust will leak out and enter the external environment, thereby polluting the environment and affecting the work of the workers. By connecting an external dust collector to the air suction port of the guide hopper 108 to suck air, a slight negative pressure inward and upward is formed in the guide hopper 108, thereby driving the generated dust to flow into the air suction port of the guide hopper 108 with the air flow, and being blocked by the filter 116 and adsorbed on the filter 116, so as to prevent the dust from flowing to the outside through the dust collector and even affecting the use of the dust collector. Because the filter 116 on the guide hopper 108 only blocks the dust and will not be discharged from the pipeline, it is necessary to clean the filter 116 regularly to avoid affecting the adsorption of dust due to long-term use.

[0049] Embodiment 2:

[0050] like Figure 1 and Figure 7 As shown, the discharge port of the one-dimensional mixer 106 is detachably connected to the guide hopper 108, the guide hopper 108 is provided with an air intake port for an external dust collector and a filter screen 116 is installed at the air intake port, and a discharge port is provided at the lower part of the guide hopper 108 and the discharge port is connected to the receiving hopper 109.

[0051] The one-dimensional mixer 106 and the guide hopper 108 are connected via a connecting flange 110 , and a silicone sealing ring 111 is provided at the connection.

[0052] A connecting frame 114 with a hollow portion is provided in the middle and upper part of the inner cavity of the guide hopper 108 , and an axial spiral blade is rotatably connected to the connecting frame 114 , and the lower end of the axial spiral blade extends to the discharge port of the guide hopper 108 .

[0053] A feed valve 107 that can be opened and closed is installed at the feed inlet of the one-dimensional mixer 106 .

[0054] It also includes a base 101, on which a support base 102 and a drive box 103 are fixedly connected, a drive shaft 104 is fixedly installed on the output shaft of the motor in the drive box 103, and a plurality of rubber wheels 105 are fixedly installed on the drive shaft 104, and two rubber wheels 105 are rotatably connected to the support base 102, and the rubber wheels 105 are in contact with a steel running track installed on the outer surface of the one-dimensional mixer 106, and the movement of the rubber wheels 105 drives the one-dimensional mixer 106 to move. Furthermore, the base 101 is universally connected to the middle part of the tail surface of the one-dimensional mixer 106, so as to prevent the axis from moving when the one-dimensional mixer 106 rotates.

[0055] The system also includes a control system that is in communication with the drive box 103. The control system is used to control the drive box 103 to realize forward and reverse rotation control, cycle number control, operation time control, operation end prompt control and other operations of the one-dimensional mixer 106.

[0056] When in use, the motor in the driving box 103 drives the driving shaft 104, because the rubber wheel 105 on the driving shaft 104 contacts the steel running track on the one-dimensional mixer 106, such as Figure 2 As shown, rubber wheels 105 are provided on both sides of the one-dimensional mixer 106. The rubber wheel 105 on the driving shaft 104 is responsible for driving and supporting the one-dimensional mixer 106 to rotate, and the rubber wheel 105 on the side away from the driving shaft 104 is responsible for supporting and assisting the rotation of the one-dimensional mixer 106, so that the one-dimensional mixer 106 is driven to rotate by the rubber wheels 105 on both sides, thereby achieving mixing and conveying of the materials in the one-dimensional mixer 106, and the forward and reverse rotation of the one-dimensional mixer 106 is achieved by controlling the forward and reverse rotation of the driving box 103, so that the materials inside the one-dimensional mixer 106 can be reciprocated and conveyed, thereby promoting mixing and improving mixing efficiency and quality.

[0057] The guide hopper 108 is connected to the discharge port of the one-dimensional mixer 106 through the connecting flange 110 and the silicone sealing ring 111. The flexibility of the silicone sealing ring 111 ensures the sealing of the connection between the connecting flange 110 and the guide hopper 108 and the one-dimensional mixer 106, ensuring that the powdered material overflows through the gap when discharging.

[0058] When the material is conveyed out of the one-dimensional mixer 106 through the discharge guide plate 120, the dust generated during the mixing of the materials also enters the guide hopper 108. The suction force generated by the dust collector at the air inlet on the guide hopper 108 drives the dust in the guide hopper 108 to move along with the airflow from the connecting flange 110 in the guide hopper 108 to the filter screen 116. When the dust contacts the filter screen 116, the dust is adsorbed on the filter screen 116 by the slight negative pressure generated by the suction force of the dust collector, so as to prevent a large amount of dust from being conveyed from the discharge port below the guide hopper 108 to the receiving hopper 109 along with the material. After using for a period of time, the filter screen 116 on the guide hopper 108 needs to be replaced and cleaned regularly to prevent the mesh opening on the filter screen 116 from being blocked by dust due to long-term use, which affects the operation of the dust collector itself or reduces the dust collector's ability to drive the dust and airflow in the guide hopper 108.

[0059] After the material enters the guide hopper 108, the material's own gravity pushes the threaded rod 113 downward to rotate on the rubber wheel 105. Because the friction between the threaded rod 113, the connecting rod 115 and the discharge port of the guide hopper 108 is very small, when the threaded rod 113 rotates, the rotation of the screw blade on the threaded rod 113 will also promote the downward transportation of the material, thereby improving the rapid transportation capacity of the material.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
