Description

[Technical field]

[0001] The present invention relates to the technical field of particle classification equipment, and in particular to a particle classification equipment. [Background technology]

[0002] Fertilizer granules are an important form of agricultural fertilizers with many characteristics and uses. They are a common form of fertilizers, usually in the form of uniform, high-hardness, powder-free granules. This form gives fertilizer granules many advantages in storage, transportation and use. For the production of fertilizer granules, a particle grading device is used. The existing particle grading device mainly consists of a filter screen and a spring connection. Personnel put chemical particles into a box, and the filter screen in the box classifies and screens the chemical particles, so that finer chemical particles fall onto the inner wall of the box, while coarser particles remain on the filter screen, thereby achieving particle size screening and grading;

[0003] Although the above scheme can screen and grade fertilizers, the following problems still exist: when the fertilizer particles are too wet, the fertilizer particles will clump together. Once the fertilizer particles clump together, the effect of the filter on screening the fertilizer particles will be reduced during the screening and grading process, and it is difficult to screen the agglomerated fertilizer particles. In addition, when the filter screens and grades the fertilizer particles, it is easy for the fertilizer particles to clog the filter. Once the filter is clogged, it is easy to make it difficult to screen and grade the fertilizer particles, and personnel are required to clear the filter to screen and grade the fertilizer particles. [Summary of the invention]

[0004] The purpose of the present invention is to solve the problems in the prior art and to provide a particle grading device capable of screening and grading fertilizer particles.

[0005] To achieve the above object, the present invention proposes a particle classification device, comprising: a box body and a plurality of screening nets arranged on the box body,

[0018] Preferably, a buffer sponge is fixedly connected to the rack, and the buffer sponge can be attached to the screening net.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The present invention arranges a heating wire on the screening net, and uses a pair of heating wires to heat the screening net. Once the screening net is heated, the motor drives the turntable to rotate, and the turntable linkage protrusion pushes the screening net to move downward. When the screening net moves downward, the screening net pushes the rack to move, so that the rack drives the spur gear to drive another rack downward to a certain extent. When the other rack moves downward, it will push another screening net to move downward. Once the protrusion on the turntable rotates to a certain position, the protrusion is separated from the screening net, and the spring drives the rack to reset, so that the screening net is reset to generate vibration, and the agglomerated fertilizer and the screening net are continuously vibrated and slapped, so that they can be dispersed, and the heating wire heats the fertilizer to evaporate the water inside, thereby realizing the fertilizer. Screening, grading and heating, while the screening net is heated by a pair of heating wires, and at the same time, the synchronous part links the screening net to push the fertilizer upward and hit the fertilizer, which can not only heat the fertilizer to evaporate the water vapor inside, but also screen and grade the fertilizer, and reduce the situation that the screening efficiency of the screening net is reduced due to the agglomerated fertilizer; 2. During the screening process of the present invention, when the screening net is blocked, the moving seat arranged on the box body moves, so that it drives the spikes on the connecting plate to be arranged relative to the screening holes on the screening net, and uses the synchronous part to drive the screening net to move downward, and the spikes pass through the screening holes of the screening net, so as to achieve the dredging of the screening holes, thereby reducing the situation that the screening effect of the screening net on the screening holes is reduced due to the blockage of the screening holes;

[0021] 3. When the screening net is unblocked, the air pump arranged on the box body can transmit high-pressure airflow through the pipeline into the chamber one, and the airflow transmitted from the chamber one enters the screening hole through the air outlet, so that the fertilizer in the blocked screening hole can be punched out, further reducing the blockage of the screening holes in the screening net;

[0022] 4. The present invention arranges a ventilation fan on the box body, and uses the ventilation fan to transmit the water vapor evaporated from the fertilizer in the box body to the outside, thereby reducing the appearance of water droplets on the inner wall of the box body due to the increase of water vapor in the box body, thereby greatly reducing the humidity in the box body, and further reducing the decrease in the drying and heating efficiency of the fertilizer due to water vapor;

[0023] 5. After the fertilizer is tapped and heated, the screening net in the present invention can smooth the fertilizer by moving the smoothing block, thereby reducing the situation where the fertilizer is placed on one side of the screening net due to the impact of tapping, and then the fertilizer can be dispersedly filtered and heated on the screening net, thereby improving the drying effect of the dispersed heating of the fertilizer and reducing the situation where the bottom of the fertilizer needs to be heated and dried due to the fertilizer being concentrated in one place.

[0035] like Figures 1 to 5 The present invention discloses a particle grading device, comprising: a box body 1 and a plurality of screening nets 2 arranged on the box body 1, wherein the screening nets 2 are provided with a plurality of sheets and arranged in a vertical direction in a row, and the screening nets 2 are mainly used for screening fertilizer particles;

[0036] It is worth mentioning that the screening net 2 is elastically slidably connected in the box body 1 in the vertical direction, and the synchronous member 3 is arranged between the box body 1 and the screening net 2. The synchronous member 3 is mainly used to drive the screening net 2 to move downward, and the heating wire 4 is fixedly connected to the screening net 2, which is mainly used to heat the screening net 2.

[0037] The synchronizer 3 in the present invention comprises:

[0038] The convex block 8, the rotating disk 7 and the motor 9, wherein the rotating disk 7 is rotatably connected to the box body 1, and the convex block 8 is fixedly connected to the rotating disk 7. The output shaft of the motor 9 fixedly connected to the box body 1 is fixedly connected to the rotating disk 7, so that the rotating disk 7 can drive the convex block 8 to rotate during the rotation process, and the convex block 8 drives the screening net 2 to move downward;

[0039] The spur gear 5, spring 10 and rack 6, when the screening net 2 moves downward, since two racks 6 are provided, the spur gear 5 is rotatably connected in the box body 1, and the spur gear 5 is respectively meshed with the rack 6, and a spring 10 is fixedly connected to the box body 1, and one end of the spring 10 is fixedly connected to the rack 6, so the rack 6 is pushed to move by the screening net 2, so that the rack 6 drives the spur gear 5 to rotate, and the spur gear 5 drives another rack 6 to drive another screening net 2 to move, thereby realizing the downward movement of the other screening net 2, when the screening net 2 moves downward to a certain position, the rotating disk drives the protrusion 8 to disengage from the screening net 2, and the screening net 2 pushes the fertilizer to move upward, when the screening net 2 pushes the fertilizer to move upward, the fertilizer will fall due to its own gravity, thereby realizing the screening net 2 to slap the fertilizer particles, when the screening net 2 slaps the fertilizer particles, the heating wire 4 heats the screening net 2, thereby realizing the heating of the fertilizer particles, thereby reducing the moisture in the fertilizer particles and reducing the agglomeration of the fertilizer particles.

[0040] Specifically, a movable seat 11 is driven to slide and connect in the box body 1, and a connecting plate 12 with a built-in chamber 28 is driven to rotate on the movable seat 11. A plurality of spikes 13 are fixedly connected to the top surface of the connecting plate 12, and the spikes 13 can be arranged relative to the screening net 2. Therefore, the sliding of the movable seat 11 can drive the connecting plate 12 to move, so that the connecting plate 12 drives the spikes 13 to move below the holes of the screening net 2, and the downward movement of the screening net 2 allows the spikes 13 to enter the screening holes of the screening net 2, thereby clearing the screening holes in the screening net 2 and reducing the blockage of the screening holes. It is worth mentioning that the movable seat 11 is driven by a cylinder 29, and the cylinder 29 is fixedly connected to the box body 1, and the output shaft is fixedly connected to the movable seat 11, so that the movement of the movable seat 11 can be realized, and the connecting plate 12 is driven by a motor 33, and the motor 33 is fixedly connected to the movable seat, and one end is fixedly connected to the connecting plate, so that the rotation of the connecting plate can be realized.

[0041] Specifically, since the air pump 14 is fixedly connected to the box body 1, the air pump 14 is communicated with the chamber 28 through a pipeline, and an air outlet 15 communicated with the chamber 28 is opened on the spike 13. The air outlet 15 is arranged opposite to the screening net 2. The air pump 14 transmits high-pressure gas through the pipeline into the chamber 28, and the chamber 28 transmits the air flow into the air outlet 15, so that the air outlet 15 transmits the air flow to clear the blocked screening net 2, thereby reducing the blockage of the screening net 2.

[0042] Specifically, a ventilation fan 16 is fixedly connected to the box body 1 , and the ventilation fan 16 is arranged opposite to the screening net 2 . The ventilation fan 16 can transmit the water vapor in the box body 1 to the outside, thereby reducing the water vapor in the box body 1 .

[0043] Specifically, since a sliding seat 17 is driven and connected in sliding in the box body 1, a lifting seat 18 is lifted and connected on the sliding seat 17, and a smoothing plate 19 is fixedly connected on the lifting seat 18, and the smoothing plate 19 is located above the screening net 2, the movement of the sliding seat 17 drives the lifting seat 18 to move. Once the sliding seat 17 moves, the lifting seat 18 is lifted and lowered, so that the lifting seat 18 drives the smoothing plate 19 to approach the fertilizer, thereby smoothing the fertilizer when the smoothing plate 19 moves. It is worth mentioning that the sliding seat 17 is driven by the second cylinder 30, and the lifting seat 18 is driven by the third cylinder 31. The second cylinder 30 is fixedly connected to the box body 1, and the output shaft is fixedly connected to the sliding seat 17, so that the movement of the sliding seat 17 can be realized, and the third cylinder 31 is fixedly connected to the sliding seat 17, and the output shaft of the third cylinder 31 is fixedly connected to the lifting seat 18, so that the lifting of the lifting seat 18 can be realized.

[0044] Specifically, a smoothing block 20 is driven to rotate on the smoothing plate 19, and inclined surfaces 21 are provided at both ends of the smoothing block 20. The inclined surfaces 21 are located above the screening net 2. The smoothing block 20 is driven by a second motor 32, and the position of the smoothing block 20 can be adjusted by fixing the output shaft of the second motor 32 fixedly connected to the smoothing plate 19 and fixedly connected to the smoothing block 20.

[0045] Specifically, a sealing block 22 is fixedly connected to the smoothing plate 19 , and a sealing strip 23 is fixedly connected to the sealing block 22 . The sealing strip 23 is in contact with the inner wall of the box body 1 . The sealing block 22 is used to seal the box body 1 , and the sealing strip 23 is used to seal the box body 1 .

[0046] Specifically, since a spring telescopic rod 24 is fixedly connected to the box body 1, one end of the spring telescopic rod 24 is fixedly connected to the bottom surface of the screening net 2, the screening net 2 can be reset by the spring telescopic rod 24, and the design of the spring telescopic rod 24 can limit the screening net 2 to reduce the rotation of the screening net 2.

[0047] Specifically, a buffer sponge 27 is fixedly connected to the rack 6 , and the buffer sponge 27 can buffer the screening net 2 and the rack 6 .

[0048] Principle of the present invention: the motor 9 drives the turntable 7 to rotate. During the rotation of the turntable 7, the turntable 7 drives the protrusion 8 to rotate, so that the protrusion 8 pushes the screening net 2. When the screening net 2 moves downward, the screening net 2 pushes the rack 6 to move, so that the rack 6 drives the spur gear 5 to rotate. Once the spur gear 5 rotates, the spur gear 5 drives another rack 6 to move, so that the other rack 6 pushes another screening net 2 to move downward, and then the protrusion 8 continues to rotate to make it separate from the screening net 2, the screening net 2 is reset, and pushes the fertilizer particles to move upward. When the fertilizer particles move upward, they will fall again due to their own gravity, so that the screening net 2 hits the fertilizer particles, thereby realizing the filtration of the fertilizer particles. When the fertilizer particles are filtered, the heating wire 4 heats the screening net 2, and the fertilizer particles are heated by the heating of the screening net 2, so that water vapor is separated from the fertilizer, thereby reducing the agglomeration of the fertilizer due to excessive water vapor.

[0049] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
