Description

Technical Field

[0001] The utility model belongs to the technical field related to screening, and particularly relates to a rotary distributor for micro powder screening equipment. Background Art

[0002] The operation of using a perforated screen surface to separate mixed materials of different particle sizes into various particle size levels is called screening. For some materials that need to be screened into fine powder, a screen with a finer aperture is required. Before the fine powder screening, some materials with slightly larger particle sizes are contained, which are transported to the relevant screening equipment for fine powder screening. However, in order to meet the high efficiency of screening, a distributor is required. However, the relevant distributor still has the following disadvantages in actual use:

[0003] The main purpose of the distributor is to guide the materials to be screened to the distribution feed. However, most distributors can only realize the distribution of materials, but cannot control the amount of each distribution, resulting in continuous distribution. Once the screening efficiency cannot be met, it is likely to lead to a decrease in screening efficiency, so it is necessary to control the amount of each distribution;

[0004] Secondly, for a structure like a hopper, after the material is placed, there is usually more material in the middle area than on both sides, resulting in uneven placement of the material;

[0005] Based on the above, usually the fabric feeder can only feed continuously. Even if the amount of fabric is controlled to be equal each time, the amount of fabric cannot be changed according to actual needs. Utility Model Content

[0006] The utility model aims to provide a rotary distributor for micro powder screening equipment, which solves the problems that a conventional continuous distributor cannot control the distribution amount to be equal each time, the distribution position is not uniform, and the distribution amount cannot be changed by arranging a distribution shaft, a distribution cylinder, a distribution scraper, a distribution cone bucket, an arc plate, and an adjustment block.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is a rotary distributor for micro powder screening equipment, comprising a distribution cylinder, a distribution cone bucket, a storage hopper, a reduction motor and a distribution shaft. The storage hopper is arranged above the distribution cylinder, and the distribution cone bucket is arranged below the distribution cylinder; the bottom surface of the distribution cone bucket is provided with distribution holes at equal intervals;

[0009] The two end walls of the distributing cylinder are rotatably connected with a distributing shaft, and the outer periphery of the distributing shaft is fixed with distributing scrapers distributed in a circular array, and arc plates are fixed on the end edges close to each other between two adjacent distributing scrapers, and screws are fixed on the opposite surfaces of the two arc plates on the same axis, and the outer sleeve of the screw is provided with an adjusting block; the opposite surfaces of the two adjacent distributing scrapers are fixed with anti-sticking chains distributed at equal intervals;

[0010] A base plate is fixed on the outer side surface of the storage hopper, and a reduction motor is fixedly mounted on the base plate.

[0011] Furthermore, a feed slot is provided at the top of the material distributing cylinder, and upper ear plates are fixed on both sides of the feed slot. A mounting ear plate is fixed at the bottom of the storage hopper, and the mounting ear plate and the upper ear plate are fastened together by fasteners.

[0012] Furthermore, a discharge slot is provided at the lower part of the material distributing cylinder, and lower ear plates are fixed on both sides of the discharge slot, and the lower ear plates are fixed to the top of the material distributing cone bucket, and the discharge slot is connected to the inside of the material distributing cone bucket.

[0013] Furthermore, a driving wheel is installed on the output shaft of the reduction motor, one end of the material distribution shaft extends out of the material distribution cylinder and the end plate and is fixed with a driven wheel, and a linkage belt is commonly sleeved outside the driving wheel and the driven wheel.

[0014] Furthermore, a protective shell is fixed on the end plate outside the driven wheel, and the driving wheel, the driven wheel and the linkage belt are all located in the protective shell.

[0015] Furthermore, a sealing cover is fixed to the upper end of the storage hopper, and two symmetrical feeding holes are formed through the sealing cover.

[0016] Furthermore, a nut is screwed onto the screw rod, the nut is closer to the center of the fabric shaft than the adjusting block, and the nut locks the adjusting block.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem that conventional continuous feeders cannot control the feeding amount to be equal each time by arranging a feeding shaft, a feeding cylinder and a feeding scraper. The material is transported into the storage hopper through an external conveying device, temporarily stored and collected, and then enters the feeding cylinder. The feeding shaft in the feeding cylinder rotates. When two adjacent feeding scrapers are aligned with the feed slot, the material in the storage hopper enters between the two adjacent feeding scrapers and fills the gap between them. Then, as the feeding shaft rotates, the feeding scraper rotates accordingly, and the feeding scraper located at the feed slot gradually rotates in a circular manner toward the discharge slot. In this process, when the feeding scraper is completely separated from the feed slot, the excess material will be scraped off to ensure that the discharge each time is the amount between the two adjacent feeding scrapers, until the gap between the feeding scrapers storing the material is connected to the discharge slot, thereby realizing quantitative feeding and discharging.

[0019] The utility model solves the problem of uneven material discharge at the distribution position by arranging a distribution cone bucket; after the distribution shaft and the distribution scraper evenly distribute the material, the material is guided downward into the distribution cone bucket, at which time the material will fall directly without more material in the middle and less material on both sides, and then the material is evenly discharged through the distribution holes at the bottom of the distribution cone bucket, thereby meeting the operation of uniform distribution.

[0020] The utility model solves the problem that the amount of material distribution cannot be changed by arranging material distribution scrapers, arc plates and adjusting blocks; a corresponding number of adjusting blocks are sleeved on corresponding screw rods, and nuts are then used to screw and lock the screw rods, so that the size of the space between adjacent material distribution scrapers can be changed, thereby changing the amount of material distribution, and flexibly controlling it according to actual needs.

The storage hopper 3 is arranged above the distribution cylinder 1, and the distribution cone hopper 2 is arranged below the distribution cylinder 1; the bottom surface of the distribution cone hopper 2 is provided with distribution holes 201 at equal intervals;

[0035] The distributing cylinder 1 is used as the main distributing place to control the output of a certain amount of micro-powder materials. The storage hopper 3 can store a certain amount of micro-powder materials as a transfer. The quantitative materials output through the distributing cylinder 1 will enter the distributing cone hopper 2, and finally be evenly output to the corresponding screening equipment through the distributing holes 201 at the bottom of the distributing cone hopper 2.

[0036] The two end walls of the material distributing cylinder 1 are rotatably connected with a material distributing shaft 6, and the outer periphery of the material distributing shaft 6 is fixed with a material distributing scraper 602 distributed in a ring array, and the end edges close to each other between two adjacent material distributing scrapers 602 are fixed with an arc plate 603, and the opposite surfaces of the two arc plates 603 on the same axis are fixed with a screw rod 6031, and the outer sleeve of the screw rod 6031 is provided with an adjustment block 604; the opposite surfaces of the two adjacent material distributing scrapers 602 are fixed with anti-sticking chains 605 distributed at equal intervals;

[0037] The rotation of the material distribution shaft 6 drives the rotation of the material distribution scraper 602. The size of the space between two adjacent material distribution scrapers 602 is the amount of material distribution at one time. Two arc plates 603 distribute the ends of the two adjacent material distribution scrapers 602, and screw rods 6031 are installed on the arc plates 603. A corresponding number of adjustment blocks 604 can be sleeved on the screw rods 6031. Then, the nuts 6032 are screwed and locked on the screw rods 6031 to change the size of the space between the adjacent material distribution scrapers 602, thereby changing the amount of material distribution, and flexibly controlling it according to actual needs; and the setting of the anti-sticking chain 605 is to avoid the problem that the micro powder materials are too dense, have high density, or are adhered and piled together when there is moisture, and the material cannot be completely discharged. When the material between the two adjacent material distribution scrapers 602 is vertically downwardly aligned with the discharge slot 105, the gravity of the anti-sticking chain 605 itself will drive the surrounding materials to fall, so that the material can be discharged quickly and completely;

[0038] A base plate 503 is fixed on the outer surface of the storage hopper 3 , and a reduction motor 5 is fixedly mounted on the base plate 503 ; the base plate 503 is used as a carrier for mounting the reduction motor 5 .

[0040] The storage hopper 3 is fixed relative to the distribution barrel 1 by installing the ear plate 301 and fixing the upper ear plate 101 to ensure structural stability, and the material in the storage hopper 3 enters the distribution barrel 1 through the feed slot 104, and then accumulates in the space between two adjacent distribution scrapers 602, which is the distribution amount for one time.

[0041] A discharge slot 105 is provided at the lower part of the material distributing cylinder 1, and lower ear plates 102 are fixed on both sides of the discharge slot 105, and the lower ear plates 102 are fixed to the top of the material distributing cone bucket 2, and the discharge slot 105 is connected to the inside of the material distributing cone bucket 2;

[0042] The bottom of the distribution cylinder 1 is connected and fixed to the distribution cone hopper 2 through the lower ear plate 102. When the distribution shaft 6 rotates, the distribution scraper 602 rotates accordingly, and the distribution scraper 602 located at the feed slot 104 gradually rotates in a circular motion toward the discharge slot 105. During this process, when the distribution scraper 602 completely leaves the feed slot 104, excess material will be scraped off to ensure that each discharge is the amount between two adjacent distribution scrapers 602, until the gap between the distribution scrapers 602 storing the material is connected to the discharge slot 105, and the material enters the distribution cone hopper 2.

[0043] A driving wheel 501 is installed on the output shaft of the reduction motor 5, one end of the material distribution shaft 6 extends out of the material distribution cylinder 1 and the end plate 103 and is fixed with a driven wheel 601, and a linkage belt 502 is commonly sleeved outside the driving wheel 501 and the driven wheel 601;

[0044] The reduction motor 5 works to drive the driving wheel 501 to rotate, and cooperates with the linkage belt 502 to transmit the rotation to the driven wheel 601, thereby rotating the cloth shaft 6.

[0045] A protective shell 4 is fixed on the end plate 103 outside the driven wheel 601, and the driving wheel 501, the driven wheel 601 and the linkage belt 502 are all located in the protective shell 4; the protective shell 4 is used to protect the transmission structure composed of the driving wheel 501, the driven wheel 601 and the linkage belt 502 to avoid harming the personal safety of external workers.

[0046] A cover 302 is fixed to the upper end of the storage hopper 3, and two symmetrical feed holes 3021 are formed in the cover 302; the cover 302 is used to seal the upper end of the storage hopper 3 to prevent the micro-powder material from escaping when entering, and the feed holes 3021 are connected to an external micro-powder conveying pipeline.

[0047] A nut 6032 is also screwed onto the screw 6031 . The nut 6032 is closer to the center of the cloth shaft 6 than the adjusting block 604 , and the nut 6032 locks the adjusting block 604 . When a certain amount of adjusting block 604 is inserted and sleeved onto the screw 6031 , the nut 6032 is rotated and locked on the screw 6031 .

[0048] The specific working principle of the utility model is as follows: first, the upper end of the storage hopper 3 is closed by the sealing cover 302, and the feeding hole 3021 is connected to the external micro-powder conveying pipeline to convey micro-powder materials into the storage hopper 3. A certain amount of micro-powder materials can be stored in the hopper. As a transfer, a corresponding number of adjustment blocks 604 are set on the corresponding screw 6031 in advance, and then the nut 6032 is used to rotate and lock the screw 6031, so as to change the size of the space between adjacent distribution scrapers 602, thereby changing the amount of distribution. Subsequently, the reduction motor 5 works to drive the driving wheel 501 to rotate, and cooperates with the linkage belt 502 to transmit the transmission to the driven wheel 601 to rotate, so that the distribution shaft 6 rotates; the material in the storage hopper 3 enters the distribution tube 1 through the feeding slot 104, and then accumulates in the space between two adjacent distribution scrapers 602. , is the amount of material distributed at one time; when the distribution shaft 6 rotates, the distribution scraper 602 rotates accordingly, and the distribution scraper 602 located at the feed slot 104 gradually rotates in a circular manner toward the discharge slot 105. In this process, when the distribution scraper 602 is completely separated from the feed slot 104, the excess material will be scraped to ensure that each discharge is the amount between two adjacent distribution scrapers 602, until the gap between the distribution scrapers 602 storing the material is connected with the discharge slot 105, and the material enters the distribution cone hopper 2. When the material between the two adjacent distribution scrapers 602 is vertically downwardly aligned with the discharge slot 105, the gravity of the anti-sticking chain 605 itself will drive the material around it to fall, so that it can be discharged quickly and completely, and finally evenly guided to the corresponding screening equipment through the distribution hole 201 at the bottom of the distribution cone hopper 2.
