Description

Technical Field

[0001] This invention relates to an oatmeal cleaning device and its process, belonging to the field of cleaning equipment. Background Technology

[0002] In the industrial processing of oats, raw material cleaning is a crucial first step. During harvesting, drying, transportation, and storage, oats inevitably become contaminated with various impurities, including clumps of soil, fine sand, small stones, and metal shavings. These impurities not only ruin the taste of the finished oat flakes but also cause severe wear and even damage to subsequent expensive processing equipment, such as mills and flaking machines, directly affecting the stability and lifespan of the production line.

[0003] The existing washing equipment conveys dry oats to the washing channel through a feeding hopper and uses high-pressure water spray to wash the material. Under the buoyancy and flow of the water, the less dense oats move forward with the water flow, while the denser sand and gravel and other heavy impurities settle at the bottom of the washing channel and are periodically discharged by the slag removal mechanism.

[0004] However, existing cleaning devices have significant shortcomings in practical applications. To achieve thorough separation of oats from surface sediment, a relatively long conveying trough is typically required to ensure sufficient soaking and tumbling time. However, in production scenarios with large feed volumes, oats tend to accumulate within the conveying trough. An excessively thick layer of accumulated oats prevents water from penetrating the material evenly, hindering effective wetting of the bottom oats, making it difficult for surface sediment to detach, and preventing the complete settling and separation of small stones. This not only significantly reduces cleaning efficiency but may also lead to some uncleaned oats being mixed into the next process, ultimately affecting product purity and the operational safety of subsequent equipment. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an oatmeal washing device and process to solve the above problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oatmeal washing device, comprising a washing tank, wherein a reflux chamber and a feeding hopper are provided inside the washing tank, the feeding hopper is connected to the reflux chamber, a movable feeder is provided at the top of the feeding hopper, a pushing auger is provided inside the feeding hopper, the motor of the pushing auger is installed outside the washing tank, the washing tank is connected to a dewatering cylinder, and the feeder includes: The system includes a feed pipe and a feed trough, the feed trough being nested within the feed pipe; a diverter installed inside the feed trough; a drive rod mounted on a bracket at the top of the feed hopper and connected to the diverter; and a driver for driving the drive rod to rotate. When the drive rod rotates, it can cause the diverter to move on the surface of the drive rod, thereby causing the feed trough to reciprocate.

[0007] Preferably, the feed trough includes: a collection chamber, a connector, the connector being disposed at the top of the collection chamber for connecting the feed pipe; and a spray side chamber, the spray side chamber being disposed on both sides of the collection chamber, the spray side chamber being connected to an external water inlet pipe.

[0008] Preferably, the material trough further includes an inner trough disposed inside the collecting chamber, the diverter is installed between the inner troughs and cooperates with the drive rod; the diverter is provided with a swing angle, and when the swing angle is exceeded, the diverter stops rotating, and then the drive rod pushes the diverter to move the collecting chamber.

[0009] Preferably, axially opposed limiting rings are provided on both sides of the collecting chamber, the limiting rings being nested and fitted with the distributor; the limiting rings include: a second ring body, which engages within a hole in the collecting chamber; a first ring body, which limits the second ring body; a limiting groove, which is provided at the front end of the first ring body; an adjusting plate, which is provided inside the limiting groove; and an adjusting screw, which is used to adjust the distance between the adjusting plate and the first ring body to buffer the distributor.

[0010] Preferably, the diverter includes: a middle cylinder and a positioning plate disposed on both sides of the middle cylinder; a limiting plate disposed between the positioning plate and the middle cylinder, the limiting plate being used to nest with the inner groove.

[0011] Preferably, a locking screw ring is provided in the middle of the positioning plate. The locking screw ring is used to cooperate with the drive rod. When the drive rod and the locking screw ring rotate relative to each other, the entire middle cylinder can be driven to move radially.

[0012] Preferably, an inlet pipe is installed inside the inner tank, and the outlet of the inlet pipe is located at the top of the middle cylinder for washing when the surface of the middle cylinder comes into contact with oat flakes.

[0013] Preferably, the limiting groove is further provided with a protrusion to block the rotational stroke of the positioning plate; when the middle cylinder moves radially, the positioning plate first contacts the adjusting plate, and swings through a transition from friction drive to contact drive.

[0014] Preferably, the diverter is further provided with a movable shaft, which is disposed between the positioning plate and the limiting plate, and the movable shaft is rotatably engaged with the first ring body and the second ring body.

[0015] As a preferred embodiment, the cleaning process of the oatmeal washing equipment includes the following steps: S1. Oat flakes enter the collection chamber of the feed trough through the feed pipe, while water flows into the spray side chamber and collides with the oat flakes to pre-soak them. S2. The driver drives the drive rod to rotate, which in turn causes the distributor to move on the surface of the drive rod, thereby causing the feed trough to move back and forth, so that the soaked oat flakes are evenly dispersed into the feed hopper. S3. The rotating auger drives the water flow, causing the oat flakes to spread out in the water and the sand and gravel to sink to the bottom. At the same time, the middle cylinder of the distributor moves radially under the drive rod and swings through the contact between the locking plate and the adjusting plate. The water inlet pipe in the inner tank assists in washing the oat flakes. S4. The washed oat flakes enter the dehydration drum, are lifted upwards and spun dry under the centrifugal force of the rotating drum, and finally flow out from the discharge port at the top of the dehydration drum.

[0016] This invention discloses an oat flake washing device and its process, which has the following advantages: The improved device optimizes the structure of the feeder, designing a movable feeding mechanism consisting of a feed pipe, a feed trough, a distributor, a drive rod, and a driver. When the driver drives the drive rod to rotate, it can cause the distributor to displace on the surface of the drive rod, thereby causing the feed trough to reciprocate. This reciprocating movement control ensures that the incoming oat flakes are evenly dispersed before entering the feed hopper, effectively solving the problem of oat flake accumulation caused by increasing the feed flow rate, and significantly improving feeding efficiency and the equipment's processing capacity.

[0017] The material collection chamber has spray side chambers on both sides, which are connected to a water source. During the feeding process, the water collides with the oat flakes, pre-soaking them. This pre-soaking design softens dust and impurities adhering to the surface of the oat flakes before they enter the washing water flow, making them easier to remove and improving the efficiency and effectiveness of subsequent washing.

[0018] The diverter, through its structural design of a middle cylinder, locking plate, limiting plate, and movable shaft, combined with the adjusting plate of the limiting ring and the adjusting screw, achieves a controllable swing angle. When the middle cylinder moves radially under the drive rod, the contact between the locking plate and the adjusting plate achieves a smooth transition from friction drive to contact drive. This design not only reduces mechanical noise and vibration but also allows the middle cylinder to make frequent and gentle contact with the oat flakes. Combined with the liquid outlet of the inlet pipe in the inner tank, it provides auxiliary rubbing and washing of the oat flakes, further improving the cleaning quality. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] To achieve thorough separation of oats from surface sediment, a relatively long conveying trough is typically required to ensure sufficient soaking and tumbling time for the material. However, in production scenarios with large feed volumes, oats tend to accumulate within the conveying trough. An excessively thick layer of accumulated oats prevents water from penetrating the material evenly, hindering effective wetting of the bottom oats, making it difficult for surface sediment to detach, and preventing the complete settling and separation of small stones. Therefore, to address these issues, this paper proposes the following technical solution: Please see Figures 1 to 6 This invention provides an oatmeal washing device and its process technology solution: its structure includes: a washing tank 1, wherein the washing tank 1 is provided with a reflux chamber 2 and a feeding hopper 4, the feeding hopper 4 is connected to the reflux chamber 2, a movable feeder 3 is provided on the top of the feeding hopper 4, a pushing auger 5 is provided inside the feeding hopper 4, the motor of the pushing auger 5 is installed outside the washing tank 1, the washing tank 1 is connected to a dewatering cylinder 6, and the feeder 3 includes: The feed pipe 31 and the feed trough 32 are nested together with the feed pipe 31; the diverter 33 is installed inside the feed trough 32; the drive rod 35 is installed on the bracket at the top of the feed hopper 4 and connected to the diverter 33; and the driver 34 is used to drive the drive rod 35 to rotate; when the drive rod 35 rotates, it can drive the diverter 33 to move on the surface of the drive rod 35, thereby driving the feed trough 32 to reciprocate.

[0029] The main structure of this application includes a washing tank 1. The washing tank 1 has an internal design with a return chamber 2 and a feeding hopper 4, which are connected to the return chamber 2. This structure facilitates the recycling of the washing water. A movable feeder 3 is installed at the top of the feeding hopper 4. A pusher auger 5 is horizontally installed inside the feeding hopper 4. The motor driving the pusher auger 5 is installed outside the washing tank 1. When the motor is working, it drives the screw of the pusher auger 5 to rotate, thereby driving the water flow. This design allows the incoming oat flakes to spread fully in the water flow, allowing heavier sand and gravel to sink quickly, while the oat flakes float and move with the water flow, achieving preliminary washing and separation.

[0030] As the core of this invention, the specific structure of the feeder 3 is as follows: Figure 2 As shown, the assembly includes a feed pipe 31, a trough 32, a distributor 33, a drive rod 35, and a driver 34. The feed pipe 31 and the trough 32 are nested together to convey the material. The trough 32 is used to temporarily hold and disperse the oat flakes. The distributor 33 is installed inside the trough 32. The drive rod 35 is mounted on a bracket at the top of the feed hopper 4 and connected to the distributor 33. The driver 34 can be a servo motor or a stepper motor to drive the drive rod 35 to rotate.

[0031] Its working principle is as follows: when the driver 34 drives the drive rod 35 to rotate, it can drive the distributor 33 to move on the surface of the drive rod 35, thereby driving the entire feed trough 32 to move back and forth. Through this reciprocating movement control, the incoming oat flakes can be initially dispersed before entering the feed hopper 4, thereby effectively avoiding the problem of material accumulation caused by increasing the feed flow rate.

[0032] like Figure 3 As shown, the specific structure of the feed trough 32 includes a collection chamber 323, a connector 321, and a spray side chamber 322. The collection chamber 323 is used to temporarily collect the oat flakes. The connector 321 is located at the top of the collection chamber 323 and is used to connect the feed pipe 31. In this embodiment, the feed pipe 31 can adopt a corrugated pipe structure to accommodate the movement of the feed trough 32; in another embodiment, a rotatable rigid connector can also be used to avoid blockage during the discharge process. The spray side chambers 322 are located on both sides of the collection chamber 323. The spray side chambers 322 are connected to a water source. During operation, the water sprayed from the spray side chambers 322 collides with the oat flakes entering from the connector 321, allowing the oat flakes to be pre-soaked, so that dust is more easily dislodged when entering the water flow.

[0033] An inner groove 324 is provided inside the collection chamber 323, and a diverter 33 is installed between the inner grooves 324 and cooperates with the drive rod 35. The diverter 33 is designed to have a certain swing angle. When the swing angle exceeds a preset value, the diverter 33 no longer rotates with the drive rod 35. At this time, the drive rod 35 will push the diverter 33, thereby driving the entire collection chamber 323 to move.

[0034] On both sides of the collecting chamber 323, there are axially opposite limiting rings 325, which are used to nest with the distributor 33. Figure 4 As shown, the specific structure of the limiting ring 325 includes a second ring body 255, a first ring body 254, a limiting groove 253, an adjusting plate 252, and an adjusting screw 251. The second ring body 255 is engaged within the hole of the collecting chamber 323. The first ring body 254 is used to limit the second ring body 255. The limiting groove 253 is located at the front end of the first ring body 254. The adjusting plate 252 is located inside the limiting groove 253. The adjusting screw 251 is used to adjust the distance between the adjusting plate 252 and the first ring body 254, thereby buffering the oscillation of the distributor 33 and reducing mechanical impact.

[0035] The specific structure of the shunt 33 is as follows: Figure 5 As shown, it includes a middle cylinder 331, a positioning plate 334, a limiting plate 332, and a movable shaft 333. The positioning plate 334 is located on both sides of the middle cylinder 331. The limiting plate 332 is located between the positioning plate 334 and the middle cylinder 331. The limiting plate 332 is used to nest with the inner groove 324. This design can prevent oat flakes from falling into the movable gap during washing and prevent the oat flakes from being crushed. The movable shaft 333 is located between the positioning plate 334 and the limiting plate 332. The movable shaft 333 rotates with the first ring body 254 and the second ring body 255 to realize the smooth swing of the diverter 33.

[0036] A locking screw ring 336 is provided in the middle of the positioning plate 334, which is used to cooperate with the drive rod 35. When the drive rod 35 rotates relative to the locking screw ring 336, it will drive the entire middle cylinder 331 to move radially. When the radial movement occurs, the positioning plate 334 first contacts the adjusting plate 252 inside the limiting groove 253. A protrusion is also provided inside the limiting groove 253, located at the bottom of the groove, to block the rotation stroke of the positioning plate 334 and limit its swing range. In order to improve the material dispersion efficiency inside the collecting chamber 323, the device will cause the middle cylinder 331 to swing frequently during use. Through the cooperation of the inlet pipe 335 and the adjusting plate 252, the transition from friction drive to contact drive is realized. Especially when the swing frequency is increased, the frictional contact between the positioning plate 334 and the adjusting plate 252 can effectively reduce noise and vibration and improve the swing efficiency.

[0037] like Figure 5 As shown, an inlet pipe 335 is also installed inside the inner tank 324, and the outlet of the inlet pipe 335 is located at the top of the middle cylinder 331. The advantage of this design is that when the surface of the middle cylinder 331 comes into contact with the oat flakes, water can flow out of the inlet pipe 335 to assist in rubbing and washing the oat flakes, further improving the cleaning effect and preventing the accumulation of dust.

[0038] like Figure 1 As shown, the equipment also includes a dehydration cylinder 6, which is connected to the rear end of the washing tank 1. The dehydration cylinder 6 has a rotatable drum inside. After the washed oat flakes enter the dehydration cylinder 6, they are lifted upwards under the action of centrifugal force, while the water is thrown out. Finally, the dehydrated oat flakes flow out from the discharge port at the top of the dehydration cylinder 6, completing the entire washing process.

[0039] This embodiment provides a cleaning process using the oatmeal cleaning equipment described in Embodiment 1, specifically including the following steps: S1. Start the equipment. Oat flakes enter the collection chamber 323 of the feed trough 32 through the feed pipe 31. At the same time, water is introduced into the spray side chamber 322. The resulting water flow collides with the incoming oat flakes, pre-soaking them. This step helps to soften dust and impurities on the surface of the oat flakes in advance, improving the subsequent cleaning effect.

[0040] S2, the driver 34 starts, driving the drive rod 35 to rotate. The rotation of the drive rod 35 causes the distributor 33 to move on the surface of the drive rod 35, thereby driving the entire feed trough 32 to move back and forth. This reciprocating motion ensures that the pre-impregnated oat flakes are evenly dispersed before entering the feed hopper 4, avoiding feeding problems caused by material accumulation.

[0041] S3. After the dispersed oat flakes enter the feed hopper 4, the auger 5 begins to rotate, causing the water in the washing tank 1 to flow. Driven by the water flow, the oat flakes are fully spread out in the water, while heavier sand and gravel sink to the bottom of the return chamber 2. Simultaneously, the middle cylinder 331 of the distributor 33 moves radially under the drive rod 35, oscillating through the contact between the locking plate 334 and the adjusting plate 252. Water continuously flows out from the inlet pipe 335 in the inner tank 324, assisting in the washing process when the middle cylinder 331 contacts the oat flake particles, further removing surface dust and impurities.

[0042] S4. The oat flakes, having completed the dynamic cleaning process, enter the dehydration drum 6 with the water flow. Inside the dehydration drum 6, the rollers rotate at high speed, causing the oat flakes to rise under centrifugal force, while simultaneously expelling water. Finally, the clean, dehydrated oat flakes flow out from the outlet at the top of the dehydration drum 6, completing the entire cleaning process.

[0043] Through the above steps, this process achieves fully automated processing of oat flakes from feeding to washing to dehydration. In particular, the reciprocating dispersion motion of the feeder 3 and the oscillating rubbing of the diverter 33 effectively solve the problem of material accumulation during high-flow feeding, while improving the washing quality.

[0044] The improved device optimizes the structure of the feeder 3, designing a movable feeding mechanism consisting of a feed pipe 31, a feed trough 32, a distributor 33, a drive rod 35, and a driver 34. When the driver 34 drives the drive rod 35 to rotate, it can cause the distributor 33 to displace on the surface of the drive rod 35, thereby causing the feed trough 32 to reciprocate. This reciprocating movement control ensures that the incoming oat flakes are evenly dispersed before entering the feed hopper 4, effectively solving the problem of oat flake accumulation caused by increasing the feed flow rate, and significantly improving feeding efficiency and equipment processing capacity.

[0045] The material trough 32 has spray side chambers 322 on both sides of the collection chamber 323. The spray side chambers 322 are connected to a water source and collide with the oat flakes during the feeding process, thus pre-soaking the oat flakes. This pre-soaking design softens the dust and impurities adhering to the surface of the oat flakes before they enter the washing water flow, making them easier to remove and improving the efficiency and effectiveness of subsequent washing.

[0046] The diverter 33, through its structural design of a middle cylinder 331, a locking plate 334, a limiting plate 332, and a movable shaft 333, along with the adjusting plate 252 of the limiting ring 325 and the adjusting screw 251, achieves a controllable swing angle. When the middle cylinder 331 moves radially under the drive rod 35, the contact between the locking plate 334 and the adjusting plate 252 achieves a smooth transition from friction drive to contact drive. This design not only reduces mechanical noise and vibration but also allows the middle cylinder 331 to make frequent and gentle contact with the oat flakes. Combined with the liquid outlet of the inlet pipe 335 in the inner tank 324, it achieves auxiliary rubbing and washing of the oat flakes, further improving the washing quality.

[0047] The above description only outlines the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and modifications based on the above description, and these changes and modifications should fall within the protection scope of the present invention.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
