Description

Technical Field

[0001] The invention relates to the technical field of rice dust removal, in particular to an intermittently position-changing and top-loading rice dust removal processing device and a processing method thereof. Background Art

[0002] Rice is a food made from paddy rice through processes such as cleaning, husking, milling and finishing. It is also the staple food for people in most areas.

[0003] The rice production process is divided into three stages: rice pre-cleaning, rice husking and rice separation, rice milling and finished product finishing. The process is rice cleaning, rice husking, rice husk separation, rice and rough separation, rough cleaning, first white rice milling, second fine milling, grading, cooling rice, white rice grading, polishing, white rice grading, second polishing, drum selection, color selection, rice blending, metering and packaging, and finished product warehousing.

[0004] In the process of rice processing, dust and other impurities are inevitably mixed into the rice due to the long process. Therefore, the rice needs to be dedusted. The existing dedusting treatment is generally to blow away the dust adhering to the rice by blowing. However, the rice and the dust are not separated in time, resulting in a part of the dust remaining in the rice storage tank, making the dedusting effect poor.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] See also Figure 1 to Figure 11 In the embodiment of the present invention, an intermittent shifting top-loading rice dust removal processing device comprises: a bracket 1, a fixing plate 2, a storage tank 3, a support plate 25, a feeding hopper 11, a dust removal component, a driving mechanism, a lifting feeding mechanism and a Maltese cross movement component and a centrifugal control component. The present application can remove dust from rice under the action of centrifugal force and the dust removal component, thereby avoiding the problem of rice moisture and rice loss caused by water washing and wind blowing. When in use, the rice to be dusted is put into the storage tank 3. At this time, the driving mechanism works and drives the lifting feeding mechanism to move through the Maltese cross movement component, so that the rice in the storage tank 3 is transported to the feeding hopper 11 through the lifting feeding mechanism. At the same time, the driving mechanism also drives the feeding hopper 11 to rotate. Under the action of centrifugal force The rice moves in the direction away from the feeding hopper 11. During the feeding process of the lifting and feeding mechanism, the centrifugal regulating component is also driven to move, and the speed of the feeding hopper 11 is increased by controlling the driving mechanism to increase the movement stroke of the rice until the rice moves to the position coordinated with the dust removal component. Under the action of the dust removal component, the rice is dusted. After the dust removal is completed, the lifting and feeding mechanism moves toward the storage tank 3 again. At the same time, the lifting and feeding mechanism also drives the centrifugal regulating component to move, and reduces the speed of the feeding hopper 11 through the driving mechanism, so that the centrifugal force on the rice in the dust removal component is reduced. At this time, under the action of gravity, the rice is separated from the dust removal component, and the above steps are repeated to achieve the effect of continuous dust removal of the rice in the storage tank 3.

[0032] The details are as follows, including: A bracket 1, on which a symmetrically arranged fixing plate 2 is fixedly mounted, a storage tank 3 for holding the rice to be processed is also fixed on the bracket 1, and a support plate 25 is fixed on the fixing plate 2; See also Figure 1-Figure 3 , Figure 5-Figure 7, a feeding hopper 11 is arranged on the bracket 1, and a dust removal assembly connected to the feeding hopper 11 and the storage tank 3 is arranged on the fixed plate 2, and the dust removal assembly includes a partition 12 fixedly installed on the side wall of the feeding hopper 11, and a filter hopper 10 is fixed on the side wall of the partition 12, and a limiting ring 9 is fixed on the filter hopper 10; the dust removal assembly also includes a support ring 8 fixedly installed on the fixed plate 2 and slidably connected to the limiting ring 9, and a cleaning roller 7 symmetrically arranged is rotatably installed at the bottom of the storage tank 3.

[0033] In detail, the feeding hopper 11 is arranged in a cone shape, and the filtering hopper 10 can be divided into three parts. The first part is arranged in a columnar shape and is located at the same horizontal plane as the partition 12. The second part is arranged in a cone shape and its inclination angle is greater than the inclination angle of the feeding hopper 11. The third part is also arranged in a columnar shape and its size is greater than that of the first part. Screen holes are provided on the second part and the third part to allow smaller impurities to pass through. A certain gap is left between the partition 12 and the first part of the filtering hopper 10. When it is necessary to process the rice, the feeding hopper 11 and the filtering hopper 10 are driven to rotate under the action of the driving mechanism, so that the rice in the feeding hopper 11 is subjected to a certain centrifugal force and moves in a direction away from the rotation center of the feeding hopper 11. As the rotation speed of the feeding hopper 11 increases, the centrifugal force on the rice in the feeding hopper 11 gradually increases until the rice leaves the feeding hopper 11 and passes through the gap between the partition 12 and the first part of the filtering hopper 10. At this time, the rice will be in a The rice falls parabolically on the second part of the filter bucket 10. Since the filter bucket 10 is also rotating, the rice is subjected to centrifugal force again and moves along the conical surface of the second part of the filter bucket 10 toward the third part of the filter bucket 10 until the rice is attached to the third part of the filter bucket 10 due to the centrifugal force. Under the action of the centrifugal force, some impurities adhering to the rice will be separated from the rice and discharged through the sieve holes. Since the filter bucket 10 is constantly rotating, when the rice in the filter bucket 10 moves to a position that fits the cleaning roller 7, the rice is dusted under the action of the cleaning roller 7. When the dust removal is completed, the driving mechanism controls the rotation speed of the feeding hopper 11 to decrease, so that the rotation speed of the filter bucket 10 is reduced. When the centrifugal force on the rice is less than the gravity on the rice, the rice will separate from the filter bucket 10 and be discharged through the gap between the first part of the filter bucket 10 and the partition 12. At this time, the untreated rice can be transported to the feeding hopper 10 again for dust removal.

[0034] Preferably, the position of the rice placed in the feeding hopper 11 can be changed by changing the centrifugal force, and the rice can be controlled to move to a position that cooperates with the dust removal component. When the dust removal is completed, the rice can also be controlled by the centrifugal force to automatically separate from the dust removal component, thereby achieving the effect of continuously removing dust from the rice.

[0035] See also Figure 1-Figure 5 , Figure 8The fixed plate 2 is also provided with a driving mechanism connected to the feeding hopper 11, the driving mechanism can drive the feeding hopper 11 to rotate, and control the rice in the feeding hopper 11 to swing into the dust removal component, and the driving mechanism can also drive the dust removal component through the feeding hopper 11 to remove dust from the rice, the driving mechanism includes a motor 20 fixedly mounted on the fixed plate 2, a transmission rod 21 connected to the output shaft of the motor 20 is rotatably mounted on the fixed plate 2, a No. 2 belt 26 is sleeved on the transmission rod 21, and a driven component connected to the No. 2 belt 26 is provided on the bracket 1, and the driven component is connected to the feeding hopper 11 and the centrifugal control group The driven component is connected with the lifting and feeding mechanism, and the transmission rod 21 is connected with the Maltese cross movement component, wherein the driven component includes a rotating sleeve 13 fixedly mounted on the bottom of the feeding hopper 11, and a turntable 27 is fixed on the rotating sleeve 13, and a plurality of slide grooves 28 equidistantly distributed in a circle are opened on the turntable 27; the driven component also includes a sliding rod 29 slidably mounted in the slide groove 28, and an arc plate 30 is fixed on the end of the sliding rod 29 away from the slide groove 28, and the arc plate 30 is connected to the No. 2 belt 26, the sliding rod 29 is connected to the centrifugal control component, and the rotating sleeve 13 is connected to the lifting and feeding mechanism.

[0036] It should be noted that the No. 1 belt 22 can be stretched or contracted to a certain extent. In the initial state, there is no rice in the feeding hopper 11. At this time, the sliding rod 29 is located at the end of the stroke away from the slide groove 28, so that the spacing between the arc plates 30 is the largest, and the No. 1 belt 22 is in a stretched state. At this time, the motor 20 works, driving the transmission rod 21 to rotate, thereby driving the No. 1 belt 22 to move. The No. 1 belt 22 will also drive the arc plate 30 to move, and drive the sliding rod 29 to move, so that the turntable 27 with the slide groove 28 moves. The turntable 27 will also drive the rotating sleeve 13 to rotate, thereby driving the feeding hopper 11 to rotate. The feeding hopper 11 will also drive the filter bucket 10 to move through the partition 12, so that the limit ring 9 rotates in the support ring 8. The transmission rod 21 will also drive the Maltese cross movement assembly to move, and control the movement of the lifting and feeding mechanism, so that the rice in the storage tank 3 is transported to the feeding hopper 11 through the lifting and feeding mechanism.

[0037] Preferably, the lifting and feeding mechanism will also drive the centrifugal control component to move during the rice conveying process, so that the sliding rod 29 continues to move toward the slide groove 28, and controls the arc plate 30 to move in the direction of approaching each other. At this time, the No. 1 belt 22 will shrink, and the speed of the turntable 27 will continue to increase, so that the speed of the feeding hopper 11 increases. Therefore, when the rice falls into the feeding hopper 11, the centrifugal force on the rice will also continue to increase, until the lifting and feeding mechanism completes the conveying and moves to the end of the stroke, and the feeding hopper 11 and the filter hopper are moved. The rotation speed of 10 reaches the maximum. At this time, the rice completely enters the filter bucket 10. When the lifting and feeding mechanism moves toward the storage tank 3, under the action of the centrifugal control component, the sliding rod 29 moves away from the slide groove 28. At this time, the No. 2 belt 26 is stretched again, and the turntable 27 is lowered, so that the centrifugal force on the rice is reduced until the gravity of the rice is greater than the centrifugal force. The rice will leave the filter bucket 10 and repeat the above steps to continuously change the rotation speed of the feeding hopper 11 to change the centrifugal force provided to the rice.

[0038] Also includes: See also Figure 1-Figure 3 , Figure 5 , Figure 6 , Figure 8-Figure 10 , a lifting and feeding mechanism is arranged on the support plate 25 and is connected to the driving mechanism and the storage tank 3. The lifting and feeding mechanism includes a limiting sleeve 16 rotatably installed on the support plate 25, and a movable rod 14 movably connected to the rotating sleeve 13 is movably installed in the limiting sleeve 16. A guide pipe 5 is fixed to one end of the movable rod 14 away from the limiting sleeve 16. A limiting component connected to the guide pipe 5 is arranged on the support plate 25. The movable rod 14 passes through the feeding hopper 11 and is connected to the centrifugal control component. The limiting sleeve 16 is connected to the Maltese cross movement component, wherein the limiting component includes a symmetrical opening on the guide pipe 5. A feeding trough 6 is set, and a hollow tube 4 movably connected to the guide tube 5 is fixed at the bottom of the storage tank 3. A limiting groove is set on the inner wall of the hollow tube 4, and a limiting rod slidably connected to the limiting groove is fixed on the outer wall of the guide tube 5. A guiding structure connected to the movable rod 14 and the limiting sleeve 16 is set on the support plate 25. The above-mentioned limiting structure includes a No. 1 spiral groove 17 which is set symmetrically on the inner wall of the limiting sleeve 16, and a No. 2 spiral groove 18 which is symmetrically set and connected to the No. 1 spiral groove 17 is also set on the inner wall of the limiting sleeve 16, and a protrusion 15 cooperating with the No. 1 spiral groove 17 and the No. 2 spiral groove 18 is fixed on the movable rod 14.

[0039] Further, the first spiral groove 17 and the second spiral groove 18 are symmetrically arranged, and the number of spiral turns of the first spiral groove 17 and the second spiral groove 18 is a quarter of a turn, and the first and second spiral grooves 17 and 18 are connected to each other at their ends. In the initial state, the protrusion 15 is located at the connection point of the first spiral groove 17 and the second spiral groove 18 away from the support plate 25, so that the movable rod 14 is located at the end of the stroke away from the support plate 25, thereby controlling the guide tube 5 to enter the storage tank 3. One of the feed slots 6 is located in the storage tank 3, and the other feed slot 6 is located in the hollow tube 4 and is in a blocked state, so that the rice in the storage tank 3 enters the guide tube 5 through the feed slot 6 and cannot be discharged. When the rice needs to be dusted, at this time, the transmission rod 21 rotates, driving the Maltese cross movement assembly to move, so that the limit sleeve 16 rotates, thereby driving the No. 1 spiral groove 17 and the No. 2 spiral groove 18 to move, and the protrusion 15 will enter the No. 1 spiral groove 17 and control the movement of the movable rod 14 , so that the guide tube 5 moves. Since the limit rod is slidably connected with the limit groove, the guide tube 5 and the movable rod 14 can only move along the length direction of the limit groove. Under the action of the protrusion 15 and the first spiral groove 17, the guide tube 5 moves in the direction away from the storage tank 3, and the two feed grooves 6 are both located in the hollow tube 4. As the guide tube 5 continues to move, the feed groove 6 located below is connected. At this time, the rice in the guide tube 5 will be transported to the feeding hopper 11 through the feed groove 6. When the protrusion 15 moves to the first spiral groove 17, the rice in the guide tube 5 will be transported to the feeding hopper 11 through the feed groove 6. When the spiral groove 17 and the second spiral groove 18 are connected toward the support plate 25, the guide tube 5 moves to the end of the stroke. At this time, the rice is transported. Under the action of the Maltese cross movement assembly, the limit sleeve 16 remains stationary for a certain period of time and then rotates again, and controls the protrusion 15 to move toward the initial position, so that the guide tube 5 moves again until the guide tube 5 returns to the initial position and the guide tube 5 is filled with rice again. Repeat the above steps to intermittently transport the rice to the feeding hopper 11 for dust removal.

[0040] See also Figure 1-Figure 3 , Figure 6 , Fig.11 The support plate 25 is also provided with a Maltese cross movement assembly connected to the lifting and feeding mechanism and the driving mechanism. The driving mechanism can drive the lifting and feeding mechanism to intermittently move through the Maltese cross movement assembly to intermittently transport the rice in the storage tank 3 to the feeding hopper 11. The Maltese cross movement assembly includes a rotating rod 23 rotatably mounted on the support plate 25, and a No. 1 belt 22 connected to the transmission rod 21 is sleeved on the rotating rod 23. A driving wheel 24 is fixed on the rotating rod 23, and a driven wheel 19 cooperating with the driving wheel 24 is fixed on the limiting sleeve 16.

[0041] Furthermore, pulleys are respectively installed on the transmission rod 21 and the rotating rod 23, and the size of the pulley on the rotating rod 23 is larger than that of the pulley on the transmission rod 21. The No. 1 belt 22 is mounted on the two pulleys, so that the transmission ratio of the transmission rod 21 and the rotating rod 23 is relatively low. When the transmission rod 21 rotates, the No. 1 belt 22 will drive the rotating rod 23 to rotate, and when the transmission rod 21 rotates one circle, the rotating rod 23 rotates less than one circle. The rotating rod 23 will also drive the driving wheel 24 to move. The transmission ratio of the driving wheel 24 to the driven wheel 19 is 4:1. When the driving wheel 24 rotates one circle, the limiting sleeve 16 fixed with the driven wheel 19 rotates a quarter of a circle. Under the action of the driving wheel 24 and the driven wheel 19, it is ensured that the rice placed in the feeding hopper 11 and the filter hopper 10 has enough time for dust removal.

[0042] See also Figure 1-Figure 6 , Figure 8 , a centrifugal control component is arranged on the bracket 1 and is connected to the driving mechanism and the lifting and feeding mechanism. The centrifugal control component can be activated when the lifting and feeding mechanism moves, and the rotation speed of the feeding hopper 11 is adjusted by the driving mechanism. The centrifugal control component includes a fixed ring 31 fixedly mounted on the movable rod 14 and symmetrically arranged, and a movable sleeve 32 abutting against the fixed ring 31 is movably mounted on the movable rod 14, and a plurality of connecting rods 33 equidistantly distributed around the circumference are hinged on the movable sleeve 32, and the connecting rod 33 is hinged to the sliding rod 29.

[0043] Specifically, in the initial state, the movable rod 14 is located at the end of the stroke away from the support plate 25, so that the movable sleeve 32 is controlled by the fixed ring 31 to be located at the end of the stroke close to the turntable 27. Under the action of the connecting rod 33, the sliding rod 29 is located at the end of the stroke away from the chute 28. At this time, the guide pipe 5 is located in the storage tank 3. When it is necessary to remove dust from the rice, the rotation speed of the feeding hopper 11 needs to be gradually increased. At this time, the movable rod 14 will move toward the support plate 25, and drive the movable sleeve 32 to move through the fixed ring 31, so as to control the sliding rod 29 to move toward the rotation plate 27 through the connecting rod 33. Movement into the slide groove 28 reduces the spacing between the arc plates 30, and the No. 2 belt 26 contracts. The transmission ratio between the transmission rod 21 and the turntable 27 will gradually change, so that the rotation speed of the turntable 27 gradually increases, thereby increasing the rotation speed of the feed hopper 11 and the filter hopper 10 by rotating the sleeve 13. Similarly, after dust removal is completed, it is necessary to reduce the rotation speed of the feed hopper 11 to ensure that the rice can smoothly leave the filter hopper 10. At this time, the movable rod 14 moves in the direction away from the support plate 25, and controls the sliding rod 29 to move again in the direction away from the slide groove 28 to reduce the rotation speed of the feed hopper 11 and the filter hopper 10.

A method for treating rice dust by using an intermittent position-changing top-loading type rice dust removal device, using the intermittent position-changing top-loading type rice dust removal device as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: placing the rice to be processed on the storage tank (3), and when the rice needs to be dusted, the driving mechanism drives the Maltese cross movement assembly to move, causing the lifting and feeding mechanism to move intermittently; Step 2: Under the action of the lifting and feeding mechanism, the rice in the storage tank (3) is intermittently transported to the feeding hopper (11); at the same time, the driving mechanism also drives the feeding hopper (11) to rotate, and under the action of centrifugal force, the rice in the feeding hopper (11) moves; Step 3: During the process of conveying rice by the lifting feeding mechanism, the centrifugal control component is also driven to move. Under the action of the centrifugal control component, the driving mechanism moves, thereby continuously increasing the rotation speed of the feeding hopper (11).
