Description

Technical Field

[0001] This utility model relates to the field of wheat washing technology, and in particular to a wheat washing and moistening device. Background Technology

[0002] Before entering the mill, wheat undergoes pretreatment processes such as rinsing and washing. With the increasing demands for raw material cleanliness in the flour milling industry, if light impurities such as dust and chaff adhering to the wheat surface are not thoroughly cleaned, it will not only reduce the whiteness of the flour but also accelerate the wear of the milling rollers, increasing the burden on subsequent sieving. In recent years, water washing has become a key step in grain cleaning due to its combined functions of destoning, dust removal, and conditioning; its processing efficiency directly affects the capacity and energy consumption of the entire production line. Currently, the common water washing configuration in workshops involves installing fixed spray pipes in an inclined tank, utilizing the natural overflow of water to carry away floating impurities, and then completing water circulation through a sedimentation tank. Some production lines also install a spiral dewatering machine at the end of the tank to simultaneously achieve material lifting and drainage.

[0003] However, these arrangements all rely on passive overflow. Once impurities accumulate in layers, they can easily block the overflow channels, forcing operators to reduce the feed rate or interrupt production for manual cleaning. Simultaneously, the circulating water is purified solely through sedimentation, causing wheat to sink to the bottom while the wheat husks inside cannot float due to accumulation. Existing technologies struggle to maintain unobstructed overflow zones under continuous high-flow conditions, resulting in incomplete husk separation and low water recycling rates, becoming the core bottleneck restricting the improvement of wheat cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a wheat washing and moistening device to solve the technical problems of incomplete wheat husk separation and easy blockage of the overflow area in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A wheat washing and moistening device includes: a washing tank, one end of which is inclined upward and has a discharge plate; a collecting tank, located at the end of the washing tank away from the discharge plate, with overflow ports on the side walls adjacent to the washing tank; a conveying mechanism, arranged in the washing tank along the inclined direction of the washing tank, for conveying the washed wheat to be discharged from the discharge plate; a circulation mechanism, connecting the washing tank and the collecting tank, for circulating water within the washing tank and the collecting tank; and an airflow mechanism, installed at the top of the washing tank, for conveying airflow to blow the wheat husks floating on the water surface toward the overflow ports.

[0006] By adopting the above technical solution, a natural water level difference is formed between the inclined washing tank and the overflow port, which, together with the conveying mechanism, enables continuous wheat discharge; the circulation mechanism keeps the water in the tank flowing, and the airflow mechanism actively pushes the floating wheat husks toward the overflow port to avoid the accumulation of impurities and improve separation efficiency.

[0007] Furthermore, an opening is provided on the side of the collection tank away from the overflow port, and a door panel is rotatably provided at the bottom of the opening. A filter screen is fixedly provided on the side of the door panel located inside the collection tank.

[0008] By adopting the above technical solution, the door panel can be opened outwards, making it easy to clean the wheat husks; the filter screen intercepts impurities while allowing water to flow back, achieving solid-liquid separation and extending the usage time of the circulating water.

[0009] Furthermore, the circulation mechanism includes a water pump and a delivery pipe; the water pump is fixed outside the cleaning tank, one end of the delivery pipe extends into the cleaning tank below the filter screen, and the other end extends into the bottom of the cleaning tank relative to one end of the overflow port.

[0010] By adopting the above technical solution, the water pump draws water from a low position to avoid sucking in the surface wheat husks, and the reverse water injection in the delivery pipe forms a bottom surge, which pushes the wheat to roll and enhances the washing effect.

[0011] Furthermore, a filter box is installed on the conveying pipe, and a gate valve is provided between the filter box and the conveying pipe.

[0012] By adopting the above technical solution, the filter box can trap fine impurities in a secondary manner, and the gate valve can close the pipeline without stopping the machine, which is convenient for flushing or replacing the filter element and ensures the cleanliness of the circulating water.

[0013] Furthermore, a pipeline connected to the delivery pipe is coiled around the bottom of the cleaning tank, and nozzles are evenly arranged on the pipeline.

[0014] By adopting the above technical solution, the nozzle sprays upward to form a uniform water flow, causing the wheat in the trough to be suspended and tumbling, shortening the impurity separation time and increasing the unit processing capacity.

[0015] Furthermore, the airflow mechanism includes an air pump, an air pipe, and air nozzles; the air pump is fixed outside the cleaning tank, the air pipe is coiled and laid on the top of the cleaning tank, the air nozzles are evenly arranged on the air pipe, and the air pump is connected to the air pipe through a connecting pipe.

[0016] By adopting the above technical solution, high-pressure gas forms a directional airflow through the nozzle, covering the entire water surface and continuously blowing wheat husks toward the overflow port, preventing impurities from flowing back and keeping the water surface clean.

[0017] Furthermore, crossbeams are provided on opposite sides of the air pipe, and the crossbeams are connected to the wall of the cleaning tank by fasteners.

[0018] By adopting the above technical solution, the crossbeam provides support, and the buckle enables quick assembly and disassembly, which facilitates the maintenance of air pipes and nozzles and reduces downtime for maintenance.

[0019] Furthermore, the conveying mechanism includes a conveyor belt, a mesh screen, and a pusher plate; the conveyor belt is rotatably disposed at the bottom of the washing tank, the mesh screen covers the conveyor belt, and the pusher plate is fixedly disposed on the conveyor belt.

[0020] By adopting the above technical solution, the mesh is permeable to retain wheat, and the pusher provides thrust in the inclined section to prevent the wheat from sliding down, thus achieving low-damage and high-efficiency wet lifting.

[0021] Compared with the prior art, the present invention has the following beneficial effects: The wheat washing and moistening equipment described in this utility model features an inclined tank that works in conjunction with airflow to remove impurities, continuously pushing wheat husks away from the washing area, preventing overflow blockage, and ensuring stable operation under high flow rates. The low-level water intake of the circulation mechanism, combined with bottom nozzles, creates an upward water flow that tumbles the wheat, improving the impurity removal rate. The combination of the filter box and gate valve enables online maintenance, keeping the circulating water clean and reducing the frequency of water changes. The door panel-filter screen structure achieves centralized collection of wheat husks and solid-liquid separation, simplifying cleaning operations and significantly improving water recycling efficiency.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] This embodiment relates to a wheat washing and moistening device, the overall structure of which is as follows: Figure 1 As shown, it includes a cleaning tank 1, a collection tank 3, a conveying mechanism 8, a circulation mechanism 9, and an airflow mechanism 10.

[0030] The washing tank 1 is inclined upward at one end, and a discharge plate 2 is installed at the inclined end. The collection tank 3 is installed at the end of the washing tank 1 away from the discharge plate 2. An overflow port 4 is opened on the side of the washing tank 1 and the collection tank 3 that are in contact with each other. A conveying mechanism 8 is installed in the washing tank 1 to discharge the washed wheat from the discharge plate 2. A circulation mechanism 9 connects the washing tank 1 and the collection tank 3 to circulate the water inside them. An airflow mechanism 10 is installed on the top of the washing tank 1 to blow the wheat husks floating on the water flow toward the overflow port 4.

[0031] It is worth mentioning that the conveying mechanism 8 is arranged along the inclined direction of the washing tank 1. Its purpose is to ensure that the wheat in the washing tank 1 can be sent out of the water with the conveying mechanism 8. The conveying mechanism 8 transports the wheat in the water to the discharge plate 2, and then collects it from the discharge plate 2 for the next operation. The water level is slightly higher than the bottom of the overflow port 4. After the wheat is washed, dust, wheat husks and other impurities float on the water level. The water flows from the overflow port 4 to the collection tank 3. This arrangement ensures that the wheat husks and other impurities can enter the collection tank 3 and be collected. The circulation mechanism 9 can ensure that the water flow in the washing tank 1 is in a flowing state, thereby driving the wheat husks to flow. The airflow mechanism 10 can cooperate with the water flow of the circulation mechanism 9 to blow the wheat husks into the collection tank 3, avoiding the accumulation of wheat husks and blockage.

[0032] Based on the above overall introduction, an exemplary structure of this embodiment is as follows: Figure 2 As shown, the collection tank 3 has an opening 5 on the side opposite to the overflow port 4. A door panel 6 is rotatably mounted on the collection tank 3 at the opening 5, and a filter screen 7 for filtering wheat husks is fixedly mounted on the door panel 6. Specifically, the door panel 6 is rotatably connected to the bottom of the opening 5 of the collection tank 3. By rotating the door panel 6, the opening 5 can be opened, thereby cleaning out the collected wheat husks and other impurities. The filter screen 7 ensures that the water flow and wheat husks can be separated, thus realizing the reuse of the water flow. The tilt angle between the filter screen 7 and the door panel 6 is set to less than 90°. This setting ensures that the filter screen 7 is in a tilted state after the door panel 6 is closed, making it convenient for impurities such as wheat husks to be discharged from the cleaning tank 1.

[0033] As a preferred implementation method, such as Figure 3 and Figure 4 As shown, the circulation mechanism 9 of this embodiment includes a water pump 901 fixedly installed on the cleaning tank 1, a conveying pipe 902 connected between the water pump 901, the cleaning tank 1, and the collection tank 3, and a filter box 903 installed on the conveying pipe 902. It should be noted that a gate valve 904 is installed between the filter box 903 and the conveying pipe 902 to control the opening and closing of the circulation mechanism 9, facilitating the cleaning of the filter box 903. The filter box 903 is used for secondary filtration of the water flow, thereby improving the quality of wheat washing. The water pump 901 is connected to the middle of the conveying pipe 902. One end of the conveying pipe 902 is located in the washing tank 1 below the filter screen 7 to prevent impurities such as wheat husks from entering the water pump 901. The other end is located at the bottom of the washing tank 1 and away from the overflow port 4 to ensure that the water flow can rush out from the bottom and achieve the tumbling of the wheat. A pipe 905 can be coiled and laid at the bottom of the washing tank 1. Spray nozzles 906 are evenly arranged on the pipe 905. The pipe 905 is connected to the conveying pipe 902. This arrangement ensures that the water flow inside the washing tank 1 can circulate, thereby driving the wheat to tumble.

[0034] As a preferred implementation method, such as Figure 5As shown, the airflow mechanism 10 of this embodiment includes an air pump 1001 fixedly installed on the cleaning tank 1, an air pipe 1002 coiled and laid on the top of the cleaning tank 1, air nozzles 1003 evenly arranged on the air pipe 1002, a connecting pipe 1005 provided between the air pipe 1002 and the air pump 1001, and crossbeams 1004 provided on opposite sides of the air pipe 1002. The crossbeams 1004 and the wall of the cleaning tank 1 are connected by fasteners. It should be noted that after the air pump 1001 is started, high-pressure gas enters the air pipe 1002 from the connecting pipe 1005 and is then ejected from the air nozzle 1003 on the air pipe 1002. After the high-pressure gas is ejected, it blows the wheat husks floating on the water surface toward the overflow port 4, ensuring that the wheat husks can flow into the collection tank 3. The function of the crossbeam 1004 and the buckle is to facilitate the disassembly and assembly of the air pipe 1002 and improve the flexibility of use. The crossbeam 1004 is fixedly installed on both sides of the air pipe 1002. The crossbeam 1004 fits against the wall of the cleaning tank 1 and can be used to support the air pipe 1002.

[0035] As a preferred implementation method, such as Figure 6 As shown, the conveying mechanism 8 in this embodiment includes a conveyor belt 801 rotatably disposed at the bottom of the washing tank 1, a mesh screen 802 laid on the conveyor belt 801, and a pusher plate 803 fixedly disposed on the conveyor belt 801. It should be noted that the conveyor belt 801 has the same structure as the conveyor belt 801 in the prior art, which consists of rollers, pulleys, motors, chains or belts, and will not be described in detail here. The purpose of setting the mesh screen 802 is to ensure that the wheat can be filtered out and the water flow will not follow the conveyor belt 801 out. If a belt is used, holes can be made in the belt to achieve the same effect. The pusher plate 803 can push the wheat out to prevent the wheat from mixing backward when it rises in the inclined section of the conveying mechanism 8.

[0036] The wheat washing and moistening equipment in this embodiment uses an inclined tank and airflow to work together to remove impurities, continuously pushing wheat husks away from the washing area, preventing overflow port 4 from clogging, and ensuring stable operation under high flow rates. The low-level water intake of the circulation mechanism 9, combined with the bottom nozzle 906, forms an upward water flow that tumbles the wheat, improving the impurity removal rate. The combination of filter box 903 and gate valve 904 enables online maintenance, keeping the circulating water clean and reducing the frequency of water changes. The door panel 6-filter screen 7 structure enables centralized collection of wheat husks and solid-liquid separation, simplifying cleaning operations and significantly improving water recycling efficiency.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
