Description

Technical Field

[0001] This utility model relates to the field of cleaning and flotation technology, specifically to a nut cleaning and flotation device. Background Technology

[0002] Nuts are a type of indeterminate fruit with a hard shell and contain one or more seeds. After harvesting, they are usually mixed with impurities, soil, and some empty shells, peels, and leaves. They need to be washed and sorted. The density of empty shells, peels, and leaves is reduced, so they can be removed by flotation in water during washing.

[0003] A Chinese patent with publication number CN217093863U discloses a nut washing and flotation device. The device involves filling a water tank and a collection tank with water, conveying the nuts to be washed and flotated into the feed end of the water tank, and simultaneously starting a water pump to spray water from the flushing nozzles. Under buoyancy, lightweight debris and empty-shelled nuts float on the surface. With the impact of water flow, overflow, and the spray from the discharge nozzles, the lightweight debris and empty-shelled nuts are discharged from the discharge port for easy collection and processing. An inclined baffle plate guides empty-shelled nuts and debris to the discharge port for easy removal. Fuller, heavier nuts sink onto the mesh conveyor belt and are conveyed and lifted along with it. The perforated mesh plate drains most of the water, facilitating nut collection.

[0004] Regarding the aforementioned technologies, when feeding nuts, if the shells and nuts are not screened, the nuts and shells are prone to sticking together when in contact with water. This causes the nuts, shells, and impurities to sink into the conveyor belt together, resulting in poor cleaning and reducing the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a nut washing and flotation device. By using this device, the problem of nuts and shells not being screened during nut feeding is solved. When nuts come into contact with water, the nuts and shells and impurities easily stick together, causing the nuts, shells and impurities to sink into the conveyor belt together and resulting in poor washing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nut washing and flotation device, comprising a flotation device, a drainage trough installed on one side of the flotation device, a shell, a flotation box fixedly installed inside the shell, a roller conveyor belt installed inside the shell, two sets of extrusion rods installed inside the shell, high-pressure nozzles installed at the lower ends of the two sets of extrusion rods, stirring blades installed inside the shell, the two ends of the stirring blades being rotatably connected to the shell, and the nozzles of the high-pressure nozzles facing the stirring blades; a C-shaped baffle plate fixedly installed at the upper end of the flotation box, multiple sets of drainage holes opened on the C-shaped baffle plate, a nozzle installed at one end of the C-shaped baffle plate, the nozzles of the nozzles being inclinedly distributed; when it is necessary to flotate nuts, the nuts are passed through the two sets of extrusion rods. Initial squeezing separates the nuts from their shells, causing them to fall into the flotation tank. At this point, the water level in the flotation tank is level with the tank's height. The high-pressure spray nozzle is then activated to wash the nuts, removing dust and impurities from their surface. During the spray cleaning process, the high-pressure spray nozzle rotates the stirring blades, which in turn stir and separate the nuts in the flotation tank. This separates the nuts and shells that were stuck together by the water. The nuts sink to the roller conveyor belt under gravity, while the shells float to the water surface due to buoyancy. Under the action of the high-pressure spray nozzle, the shells are discharged outside the device through the C-shaped baffle. Simultaneously, the spray nozzle washes the C-shaped baffle. Because the force of the spray nozzle is less than that of the high-pressure spray nozzle, impurities are discharged through both sides of the C-shaped baffle.

[0007] Preferably, the outer shell is provided with two sets of drainage holes, the drainage holes being matched with the drainage trough. The drainage holes are located at the upper end of the flotation tank. Under the action of the high-pressure nozzle, impurities are discharged through the drainage holes on both sides of the C-shaped baffle plate. The discharged impurities flow through the drainage trough to the collection device for recycling and secondary cleaning.

[0008] Preferably, a feeding device is fixedly installed on one side of the shell, a cleaning device is fixedly installed inside the shell, and multiple sets of support legs are fixedly installed at the lower end of the shell. Nuts that have undergone flotation treatment have their surface dirt cleaned by the cleaning device, and the cleaned nuts enter the collection box through the feeding device for further processing.

[0009] Preferably, the interior of the outer shell has multiple sets of sliding grooves, which are matched with the cleaning device. The cleaning device cleans nuts of different sizes by sliding within the sliding grooves.

[0010] Preferably, a limiting plate is provided on one side of the extrusion rod, and the two ends of the limiting plate are fixedly connected to the outer shell. When feeding materials into the flotation tank, the limiting plate acts as a barrier to prevent nuts that have not undergone extrusion processing from directly entering the flotation tank for cleaning.

[0011] Preferably, the cleaning device includes a cleaning roller, with connecting blocks fixedly installed at both ends of the cleaning roller. Elastic elements are fixedly installed at both the upper and lower ends of the connecting blocks. The end of the elastic element away from the connecting block is fixedly connected to the outer shell. The connecting block is slidably connected to the outer shell. When it is necessary to clean the nuts after flotation, the roller conveyor belt and the cleaning roller cooperate to perform reverse tumbling cleaning, so that the nuts of different sizes are evenly cleaned by the cleaning roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention proposes a nut washing and flotation device. When flotation is required, the nuts are initially squeezed by two sets of extrusion rods, causing the nuts and shells to separate initially and fall into the flotation tank. At this point, the water level in the flotation tank is level with the height of the tank. A high-pressure spray nozzle is activated to wash the nuts, removing dust and impurities from their surface. During the spray cleaning, the high-pressure spray nozzle rotates the stirring blades, which stir and separate the nuts in the flotation tank, causing the nuts and shells that are stuck together in the water to separate. The nuts sink to the roller conveyor belt under gravity, while the shells float to the water surface under buoyancy and are discharged outside the device through a C-shaped baffle under the action of the high-pressure spray nozzle. At the same time, the C-shaped baffle is washed by the spray nozzle. Since the force of the spray nozzle is less than that of the high-pressure spray nozzle, impurities are discharged through both sides of the C-shaped baffle. This device can effectively separate nuts and shells that are stuck together when they first enter the flotation tank, thus enhancing the flotation efficiency of the device.

The nozzles of the high-pressure nozzles 17 are positioned facing the stirring blades 14. A C-shaped baffle plate 16 is fixedly installed at the upper end of the flotation box 15, with multiple sets of drainage holes 161 opened on the C-shaped baffle plate 16. A nozzle 162 is installed at one end of the C-shaped baffle plate 16, with the nozzles of the nozzle 162 distributed at an angle. When it is necessary to float nuts, the nuts are passed through the two sets of extrusion rods 12. Initial squeezing causes the nuts and shells to separate and fall into the flotation tank 15. At this point, the water level in the flotation tank 15 is level with the height of the tank. The high-pressure spray nozzle 17 is activated to wash the nuts, removing dust and impurities from their surface. During the spray cleaning process, the high-pressure spray nozzle 17 rotates the stirring blade 14, which stirs and separates the nuts in the flotation tank 15, causing the nuts and shells that are stuck together by water to separate. The nuts sink to the roller conveyor belt 18 under gravity, while the shells float to the water surface under buoyancy. Under the action of the high-pressure spray nozzle 17, the shells are discharged outside the device through the C-shaped baffle plate 16. At the same time, the C-shaped baffle plate 16 is washed by the spray nozzle 162. Since the force of the spray nozzle 162 is less than that of the high-pressure spray nozzle 17, the impurities are discharged through both sides of the C-shaped baffle plate 16.

[0023] Combination Figures 1-2 The outer shell 11 has two sets of drainage holes 111. The drainage holes 111 are matched with the drainage trough 2. The drainage holes 111 are located at the upper end of the flotation tank 15. Under the action of the high pressure nozzle 17, the impurities are discharged through the drainage holes 111 on both sides of the C-shaped baffle plate 16. The discharged impurities flow through the drainage trough 2 to the collection device for recycling and secondary cleaning.

[0024] Combination Figures 1-2 A feeding device 3 is fixedly installed on one side of the outer shell 11, a cleaning device 4 is fixedly installed inside the outer shell 11, and multiple sets of support legs 112 are fixedly installed at the lower end of the outer shell 11. Nuts that have undergone flotation treatment have their surface dirt cleaned by the cleaning device 4, and the cleaned nuts enter the collection box through the feeding device 3 for further processing.

[0025] Combination Figures 1-4 The shell 11 has multiple sliding grooves 113 inside. The sliding grooves 113 are matched with the cleaning device 4. The cleaning device 4 cleans nuts of different sizes by sliding in the sliding grooves 113.

[0026] Combination Figures 1-2 A limiting plate 13 is provided on one side of the extrusion rod 12. The two ends of the limiting plate 13 are fixedly connected to the outer shell 11. When feeding material into the flotation box 15, the limiting plate 13 blocks the flow to prevent nuts that have not been extruded from directly entering the flotation box 15 for cleaning.

[0027] Combination Figure 1 , Figure 5 The cleaning device 4 includes a cleaning roller 41. Both ends of the cleaning roller 41 are fixedly installed with connecting blocks 42. Both the upper and lower ends of the connecting blocks 42 are fixedly installed with elastic elements 43. The end of the elastic element 43 away from the connecting block 42 is fixedly connected to the outer shell 11. The connecting block 42 is slidably connected to the outer shell 11. When it is necessary to clean the nuts after flotation, the roller conveyor belt 18 cooperates with the cleaning roller 41 to perform reverse tumbling cleaning, so that the nuts of different sizes are evenly cleaned by the cleaning roller 41.

[0028] Working principle: The nuts are initially squeezed by two sets of extrusion rods 12 to separate the nuts and shells, and then fall into the flotation tank 15. The high-pressure spray pipe 17 is activated to wash the nuts and remove surface dust and impurities. At the same time, the stirring blades 14 are driven to stir and separate the nuts and shells that are stuck to the water. The nuts sink onto the roller conveyor belt 18, and the shells float to the water surface and are discharged through the C-shaped baffle plate 16. Impurities are discharged through the drainage holes 111 on both sides of the C-shaped baffle plate 16 and flow to the collection device through the drainage trough 2. The flotation nuts are tumbled in the opposite direction by the roller conveyor belt 18 and the cleaning roller 41, and then enter the collection tank through the feeding device 3.
