The rice dust removal device shown in the figures 1-7 comprises an outer barrel 1, a rice bin 2, a sponge cover 3, a net bag 4, a blocking ball 5, a flow dividing net 6, a net plug 7, a sponge ball 8, an air ring 9, a rice box 10 and a frame 11.

In the present embodiment, the outer cylinder 1 is a cylindrical shape which penetrates vertically, and may be another shape which penetrates vertically; the sponge cover 3, the net bag 4 and the net plug 7 are sequentially arranged in the outer barrel 1 at intervals from top to bottom and divide the cavity in the outer barrel 1 into a primary dust removing bin 12 and a secondary dust removing bin 13 from top to bottom.

A plurality of sponge strips 15 are arranged on the lower end surface of the sponge cover 3; the sponge strips 15 are arranged in a staggered manner; the upper end of the sponge cover 3 is provided with a detachable end cover 16; the end cover 16 is connected with the upper end of the outer cylinder 1; the end cover 16 is provided with a net or a vent hole; the space between the sponge cover 3 and the end cover 16 in the outer cylinder 1 is used for buffering dust, and after the dust in the primary dust removing bin 12 and the secondary dust removing bin 13 is blown out by the air ring 9, the dust can be adsorbed on the lower end of the sponge cover 3 and the sponge strips 15; of course, if the sponge cover 3 is not replaced or cleaned for a long time, dust can enter the space between the sponge cover 3 and the end cover 16 and even can overflow from the net or the vent hole at the upper end of the end cover 16; therefore, the sponge cover 3 also needs to be taken out periodically to be cleaned, and the sponge cover 3 is very convenient to disassemble and assemble and can be directly taken out outwards.

The net bag 4 is funnel-shaped, and the lower end of the net bag is provided with a leakage opening 20; the blocking ball 5 is arranged in the primary dedusting bin 12, and the outer diameter of the blocking ball 5 is larger than the caliber of the leakage opening 20; the outlet end of the rice bin 2 is communicated with the primary dedusting bin 12, and the outlet end of the rice bin 2 is provided with a flow limiting valve 14; the amount of the rice entering the primary dedusting bin 12 can be limited through the action of the flow limiting valve 14, the dedusting effect is affected by too much rice entering at one time, the rice is easy to accumulate, and the dedusting efficiency is low due to too little rice entering at one time.

The shunt net 6 is arranged on the net plug 7 in a conical shape, and a pointed cone at the upper end of the shunt net 6 is aligned with the leakage port 20 and keeps a distance; when the rice leaks downwards from the leakage opening 20, the rice can impact the flow distribution net 6 and scatter towards the edge under the flow distribution effect of the flow distribution net 6, but the dust cannot scatter, so that the separation of the dust and the rice is realized; the rice dispersion is around the back with the sponge ball 8 bumps in the secondary dust removal storehouse 13, because sponge ball 8 receives wind-force effect can float aloft, receive behind the reaction force of the rice of equidirectional not, sponge ball 8 can take place irregular rotation, rotate the in-process and also can take place the friction with the rice, thereby erase the dust on rice surface, the rice is not with the friction of 1 inner wall of urceolus and erase the dust, and a small amount of dust of 1 inner wall of urceolus can be cleared up to

sponge ball

8, 1 inner wall of urceolus need not the clearance, it is more convenient to compare current centrifugal dust collector. And the rice and the sponge ball 8 do not move under the action of centrifugal force, but irregularly move and rotate under the action of the upward wind force of the wind ring 9, the rice cannot collide with the sponge ball 8 violently, and the sponge ball 8 has flexibility and a buffering effect, so that the rice cannot break. The rice box 10 is arranged at the lower end of the wind ring 9; the frame 11 is connected with the outer cylinder 1.

A plurality of sponge balls 8 are distributed in the secondary dust removal bin 13; the weight of the sponge ball 8 is less than that of the blocking ball 5; in the embodiment, the meshes of the net bag 4 are smaller than 2 mm; the meshes of the shunting net 6 are less than 3 mm; the mesh of the mesh plug 7 is larger than 4 mm. In order to make contact with the surface of the rice and have better effect of wiping off dust, the outer spherical surface of the sponge ball 8 can be provided with a plurality of bulges. In addition, the side wall of the outer cylinder 1 is provided with a bin gate for taking out the sponge ball 8. Because the sponge ball 8 can adsorb more dust after being rubbed with the rice, in order to remove dust, when the dust on the surface of the sponge ball 8 is too much, the dust removing effect is reduced, and therefore, the sponge ball 8 can be replaced by opening the door; in addition, also can be with sponge ball 8 drench, humidity is preferred not to extrude water for being suitable, because sponge ball 8 has certain humidity, it is better to wipe rice dust effect, and because sponge ball 8 atress is not centrifugal force, can not be thrown away water and excessively drenched the rice, can not cause the rice nutrition to run off.

The wind ring 9 is a hollow circular ring structure and is horizontally arranged at the lower end of the net plug 7; the wind ring 9 is coaxially connected with the outer cylinder 1; the inner diameter of the wind ring 9 is larger than or equal to that of the outer cylinder 1; the upper end and the lower end of the wind ring 9 respectively protrude back to the opposite direction to form arc surfaces; the inner wall of the wind ring 9 close to the lower end is provided with a circle of open slots which are coaxial with the wind ring 9; the width of the opening of the open slot is 1 mm; the open slot is inclined upwards; the inner diameter of the air ring 9 is gradually reduced from top to bottom; the outer wall of the wind ring 9 is provided with a wind box 17; a motor 18 and a blade 19 which are matched with each other are arranged in the air box 17; an air inlet is arranged on the side wall or one end of the air box 17, and an air outlet communicated with the interior of the air ring 9 is arranged on the other end of the air box 17; due to the special structural design of the air ring 9, the open slot generates great upward air volume, the rice is blown away under the action of great wind power, and the blocking ball 5 can be blown open, so that the rice in the primary dedusting bin 12 can fall into the secondary dedusting bin 13; because what set up in 1 upper end of urceolus is sponge lid 3 and is equipped with end cover 16 of net or air vent, consequently the air current that the wind ring 9 produced overflows to the urceolus 1 outside upwards through sponge lid 3 and end cover 16 back, and the dust is filtered and is adsorbed on sponge lid 3, sponge ball 8 and sponge strip 15, reaches fine rice dust removal effect.

In addition, the rice dust removing device of the embodiment further comprises a controller and a switch which are connected with the motor 18 and used for controlling the rotating speed of the motor 18. Of course, the controller may also be connected to the constrictor valve 14.

The controller controls the rotating speed of the motor 18, as shown in fig. 5, when the controller controls the motor 18 to rotate at a high rotating speed, the blocking ball 5 is blown open, the rice in the primary dedusting bin 12 can enter the secondary dedusting bin 13 through the leakage opening 20 of the string bag 4, and meanwhile, the rice in the secondary dedusting bin 13 and the sponge ball 8 are subjected to running friction, so that the rice can not drop basically. As shown in fig. 6, when the controller controls the motor 18 to rotate at a rotating speed, the blocking ball 5 cannot be blown open any more, and the rice in the primary dust removal bin 12 cannot fall off any more; however, because the mass of the rice and the sponge balls 8 is less than that of the blocking balls 5, the rice and the sponge balls 8 can still move in the secondary dedusting bin 13, and the rice in the secondary dedusting bin 13 is further dedusted. As shown in fig. 7, when the controller controls the motor 18 to rotate at a low speed or even not to rotate, the sponge ball 8 falls on the net plug 7, the rice after dust removal of the secondary dust removal bin 13 directly falls into the rice box 10, the rice box 10 can be directly taken out to obtain clean rice after dust removal, and the rice dust removal device of the embodiment can be suitable for large-scale rice processing factories and can also be suitable for hotels, dining halls or families.
