Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, and in particular to an airflow segmentation device. Background Technology

[0002] The production process of toner granules can be divided into two main categories according to their uses: office consumables toner (such as printer toner) and industrial granular toner (such as activated carbon granules). They are mainly manufactured using physical pulverization or chemical synthesis methods. After the toner is finished, it is usually transported by pneumatic conveying, which uses airflow and pipelines to transport and transfer the toner. In pneumatic conveying, an airflow segmentation device is usually used to split the original airflow into two parts, which, together with the corresponding connected pipelines, transport the toner to two different locations. However, the existing airflow segmentation device is not convenient for adjusting the relative airflow of the two branch pipelines. Utility Model Content

[0003] This invention provides an airflow segmentation device that solves the problem in the prior art where existing airflow segmentation devices are inconvenient for adjusting the relative airflow magnitudes of the two branch pipes.

[0004] An airflow segmentation device includes a segmentation box. A main vent pipe is fixedly installed through the upper end face of the segmentation box, and the lower end of the main vent pipe extends into the segmentation box. A rotating column is rotatably installed on the inner wall of the segmentation box. A left baffle and a right baffle are symmetrically fixed on the upper surface of the rotating column. A partition component is provided between the lower surface of the rotating column and the bottom of the segmentation box. A left vent pipe and a right vent pipe are symmetrically connected to the lower end face of the segmentation box. A left vent slot for use with the left vent pipe is opened through the inner bottom of the segmentation box, and a right vent slot for use with the right vent pipe is also opened through the inner bottom of the segmentation box. A drive mechanism for use with the rotating column is provided on the segmentation box.

[0005] As a further technical solution of this utility model, one end of the rotating column rotatably passes through the segment box and is fixedly fitted with a large gear ring. A working motor is provided on one side of the segment box. A driving column is rotatably provided between the end of the driving shaft of the working motor and the outer wall of the segment box. A small gear ring is fixedly fitted on the outer surface of the driving column. The small gear ring meshes with the large gear ring. A support member is provided on the segment box to cooperate with the working motor.

[0006] As a further technical solution of this utility model, the support member includes a support plate fixed to the outer wall of the segment box, a working motor fixed to the upper end face of the support plate, and multiple stiffening plates fixed between the lower end face of the support plate and the outer wall of the segment box.

[0007] As a further technical solution of this utility model, the partition component includes a partition plate fixed to the bottom of the segment box, an elastic block fixed to the upper end surface of the partition plate, and an arc-shaped groove for use with the rotating column on the upper end surface of the elastic block.

[0008] As a further technical solution of this utility model, two guide seats are symmetrically fixed at the inner bottom of the segment box, and an arc-shaped guide groove is opened on the upper end surface of each guide seat.

[0009] As a further technical solution of this utility model, the upper surfaces of the left and right baffles are provided with abutment grooves.

[0010] As a further technical solution of this utility model, inclined plates are movably and through-equipped on both sides of the segmented box, and a connecting notch for use with the abutting notch is opened at the lower end of each inclined plate. A second drive mechanism for use with the corresponding inclined plate is provided on both sides of the segmented box.

[0011] As a further technical solution of this utility model, each of the second driving mechanisms includes a mounting seat fixed on the side wall of the segment box, and multiple cylinders are fixed on the side wall of each mounting seat. A connecting plate is fixed at the upper end of the inclined plate, and the end of the cylinder extension and retraction end is fixedly connected to the side wall of the connecting plate.

[0012] As a further technical solution of this utility model, a plurality of guide rods are fixedly provided on the side wall of each of the mounting seats, and each guide rod movably passes through the connecting plate.

[0013] As a further technical solution of this utility model, the upper end of the main vent pipe is connected to a main airflow pipe, the lower end of the left vent pipe is connected to a left airflow pipe, and the lower end of the right vent pipe is connected to a right airflow pipe.

[0014] The beneficial effects of this utility model are:

[0015] When this invention is in use, if there is a small shortage of material in silo B and a large shortage in silo A, the drive mechanism can cause the rotating column to deflect clockwise by a certain angle (towards the right airflow pipe). This causes the left and right baffles to deflect together by a certain angle. Under the guidance of the left baffle, most of the airflow and toner delivered into the segmented box by the main vent pipe is directed towards the left vent pipe, while only a small portion of the airflow and toner flows towards the right vent pipe. This allows a large amount of toner to be delivered to silo A and a small portion to silo B, making it convenient to use. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] Reference Figures 1-10An airflow segmentation device includes a segmentation box 100. A main vent pipe 101 is fixedly installed through the upper end face of the segmentation box 100. The lower end of the main vent pipe 101 extends into the segmentation box 100. A rotating column 102 is rotatably installed on the inner wall of the segmentation box 100. A left baffle 103 and a right baffle 104 are symmetrically fixed on the upper surface of the rotating column 102. A partition component is provided between the lower surface of the rotating column 102 and the bottom of the segmentation box 100. A left vent pipe 105 and a right vent pipe 106 are symmetrically connected to the lower end face of the segmentation box 100. A left vent groove 107 for use with the left vent pipe 105 is opened through the bottom of the segmentation box 100. A right vent groove 108 for use with the right vent pipe 106 is also opened through the bottom of the segmentation box 100. A drive mechanism for use with the rotating column 102 is provided on the segmentation box 100.

[0029] In the initial state, both the left baffle 103 and the right baffle 104 are vertical, which can divide the segment box 100 into a left area and a right area.

[0030] The upper end of the main ventilation pipe 101 is connected to the main airflow pipe 207, the lower end of the left ventilation pipe 105 is connected to the left airflow pipe 208, and the lower end of the right ventilation pipe 106 is connected to the right airflow pipe 209.

[0031] The main airflow pipe 207 delivers the airflow containing carbon powder to the segment box 100. The end of the left airflow pipe 208 is connected to the external material hopper A, and the end of the right airflow pipe 209 is connected to the external material hopper B.

[0032] When this solution is in use, if there is a small shortage of material in silo B and a large shortage in silo A, the drive mechanism can cause the rotating column 102 to deflect clockwise by a certain angle (towards the right airflow pipe 209). This will cause the left baffle 103 and the right baffle 104 to deflect together by a certain angle. Under the guidance of the left baffle 103, most of the airflow and toner delivered into the segment box 100 by the main vent pipe 101 will be directed towards the left vent pipe 105, while only a small portion of the airflow and toner will flow towards the right vent pipe 106. This will deliver a large amount of toner to silo A and a small portion of toner to silo B, making it convenient to use.

[0033] Since there is less material shortage in hopper B, the amount of toner conveyed can be easily controlled by reducing the corresponding airflow, thus avoiding over-conveying.

[0034] One end of the rotating column 102 rotatably passes through the segment box 100 and is fixedly fitted with a large gear ring 109. A working motor 110 is provided on one side of the segment box 100. A driving column 111 is rotatably connected between the end of the driving shaft of the working motor 110 and the outer wall of the segment box 100. A small gear ring 112 is fixedly fitted on the outer surface of the driving column 111. The small gear ring 112 meshes with the large gear ring 109. A support member is provided on the segment box 100 to cooperate with the working motor 110. The working motor 110 is existing technology and has an angle locking function.

[0035] When the drive shaft of the working motor 110 drives the drive column 111 to rotate, it will drive the small gear ring 112 to rotate, thereby driving the large gear ring 109 to rotate, which in turn drives the rotating column 102, the left baffle 103 and the right baffle 104 to rotate.

[0036] The support includes a support plate 113 fixed to the outer wall of the segment box 100, a working motor 110 fixed to the upper end face of the support plate 113, and a plurality of stiffening plates 114 fixed between the lower end face of the support plate 113 and the outer wall of the segment box 100.

[0037] The working motor 110 is supported by the cooperation of the support plate 113 and the stiffening plate 114.

[0038] The partition assembly includes a partition plate 115 fixed to the bottom of the partition box 100. An elastic block 116 is fixed to the upper end surface of the partition plate 115. An arc-shaped groove is opened on the upper end surface of the elastic block 116 to cooperate with the rotating column 102. The rotating column 102 rotates against the inner wall of the arc-shaped groove.

[0039] The lower section of the segment box 100 is divided by the cooperation of the partition plate 115 and the elastic block 116.

[0040] The inner bottom of the segment box 100 has two symmetrically fixed guide seats 117, and each guide seat 117 has an arc-shaped guide groove 118 on its upper surface.

[0041] The combination of the guide seat 117 and the arc-shaped guide channel 118 facilitates the guiding of airflow containing carbon powder.

[0042] The upper surfaces of both the left baffle 103 and the right baffle 104 are provided with abutment grooves 200.

[0043] When silo A is short of material and silo B is not short of material, the rotating column 102 drives the left baffle 103 and the right baffle 104 to rotate clockwise until the contact notch 200 of the right baffle 104 is attached to the inner wall of the segment box 100. At this time, the airflow delivered into the segment box 100 by the main vent pipe 101 can only be discharged through the left vent pipe 105, so that only silo A is supplied with material and silo B is not supplied with material. Thus, this application can deliver different specifications of toner to silo A and silo B respectively.

[0044] Both sides of the segment box 100 are provided with inclined plates 201. Each inclined plate 201 has a connecting notch 202 at its lower end for use with the abutment notch 200. Both sides of the segment box 100 are provided with a drive mechanism 2 for use with the corresponding inclined plate 201.

[0045] When the contact notch 200 of the right baffle 104 is attached to the inner wall of the segment box 100, the connecting notch 202 at the end of the inclined plate 201 is attached to the contact notch 200 of the left baffle 103, thereby cooperating to guide the airflow and prevent material accumulation between the contact notch 200 of the left baffle 103 and the inner wall of the segment box 100.

[0046] Each drive mechanism includes a mounting base 203 fixed to the side wall of the segment box 100. Multiple cylinders 204 are fixed on the side wall of each mounting base 203. A connecting plate 205 is fixed to the upper end of the inclined plate 201. The end of the telescopic end of the cylinder 204 is fixedly connected to the side wall of the connecting plate 205.

[0047] During the process of the contact notch 200 of the right baffle 104 fitting into the inner wall of the segment box 100, the telescopic end of the cylinder 204 first extends, pushing the connecting plate 205 and the inclined plate 201 away from the right baffle 104. After the contact notch 200 of the right baffle 104 fits into the inner wall of the segment box 100, the telescopic end of the cylinder 204 retracts, driving the connecting plate 205 and the inclined plate 201 to reset, so that the end of the inclined plate 201 abuts against the end of the left baffle 103.

[0048] Multiple guide rods 206 are fixedly installed on the side wall of each mounting base 203, and each guide rod 206 movably passes through the connecting plate 205.

[0049] The guide rod 206 ensures the stability of the connecting plate 205 and the inclined plate 201 during movement.

[0050] When this utility model is in use, if there is a small shortage of material in silo B and a large shortage in silo A, the drive mechanism can cause the rotating column 102 to deflect clockwise by a certain angle (towards the right airflow pipe 209). This will cause the left baffle 103 and the right baffle 104 to deflect together by a certain angle. Under the guidance of the left baffle 103, most of the airflow and toner transported into the segment box 100 by the main vent pipe 101 will be directed towards the left vent pipe 105, while only a small portion of the airflow and toner will flow towards the right vent pipe 106. This will transport a large amount of toner to silo A and a small portion of toner to silo B, making it convenient to use.

[0051] The above-disclosed embodiments are merely preferred embodiments of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
