Abstract
Description
Technical Field
[0001] This utility model belongs to the field of nut cleaning and screening technology, specifically relating to a nut cleaning and flotation device. Background Technology
[0002] Freshly shelled nuts contain a lot of impurities, including broken green husks, broken leaves, twigs, and stones. Some of these impurities float on water, while others sink to the bottom. Therefore, flotation is needed to separate the nuts from the impurities.
[0003] Most existing nut flotation methods involve pouring nuts into a water tank, manually washing them in the tank, and then scooping them out, leaving impurities in the water. This method is inefficient and labor-intensive for workers. Utility Model Content
[0004] In order to overcome the problems existing in the background technology, this utility model provides a nut washing and flotation device.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a nut washing and flotation device, comprising: a first washing device, a flotation device connected to the first washing device, and a second washing device connected to the flotation device. The flotation device comprises: a square strip-shaped flotation cell, a first grid plate disposed within the flotation cell, and a second grid plate disposed within the flotation cell. The first grid plate has an upward inclined slope at one end near the first washing device, and a vertical grid plate is provided at the other end of the first grid plate. The second grid plate is horizontally located below the first grid plate and divides the flotation cell into upper and lower parts.
[0006] Preferably, the flotation cell is provided with a second water inlet pipe at one end near the first cleaning device, a nut outlet located above the second grid plate at the other end of the flotation cell, and a water outlet located below the second grid plate at the other end of the flotation cell.
[0007] Preferably, the nut outlet is connected to an inclined spiral elevator, and the outlet of the spiral elevator is connected to the second cleaning device.
[0008] Preferably, the first cleaning device includes: a first cylinder with an open upper end, a first valve disposed at the bottom of the first cylinder and communicating with the flotation cell, a first water inlet pipe disposed on the side wall of the first cylinder, a first crossbeam disposed at the opening of the first cylinder, a first servo motor disposed on the first crossbeam, a first reducer disposed on the first servo motor, a first transmission shaft connected to the output shaft of the first reducer, and a first stirring paddle disposed on the first transmission shaft.
[0009] Preferably, the second cleaning device includes: a second cylinder with an open upper end, a second valve at the bottom of the second cylinder, a third water inlet pipe on the side wall of the second cylinder, a second crossbeam at the opening of the second cylinder, a second servo motor on the second crossbeam, a second reducer on the second servo motor, a second drive shaft connected to the output shaft of the second reducer, and a second agitator on the second drive shaft.
[0010] Preferably, a nut collection trough is provided below the second valve, and one side wall of the nut collection trough is a filter screen plate.
[0011] The beneficial effects of this utility model compared with the prior art are as follows:
[0012] This invention uses a first cleaning device to initially clean the nuts, separating them from impurities. The nuts then enter the flotation cell through a first valve. The nuts and impurities move forward with the water flow in the flotation cell. Impurities with high buoyancy are intercepted by the grid plate when passing through the first grid, while impurities with low buoyancy pass through the second grid plate and settle to the bottom. The nuts flow between the first and second grid plates to the nut outlet, where they are lifted by a screw conveyor to the second cleaning mechanism for final cleaning and collection. This invention achieves both nut cleaning and impurity separation. Attached Figure Description

The first grid plate 5 filters impurities with high buoyancy, and the grid plate 7 intercepts impurities with high buoyancy, which are then manually removed after a certain amount accumulates. Impurities with low buoyancy pass through the second grid plate 6 and settle to the bottom. Nuts flow between the first grid plate 5 and the second grid plate 6 to the nut outlet 9, where they are lifted by a screw conveyor 11 to the second washing mechanism for final washing and collection. Nuts cannot pass through the first grid plate 5 and the second grid plate 6.

The flotation tank 4 also has a water outlet 10 located below the second grid plate 6 at the other end. The second water inlet pipe 8 is connected to one of the following: tap water, a water pump, or a water tank, requiring a continuous water flow to allow the nuts to move forward with the water flow. The water at the water outlet 10, after being filtered to remove impurities, can be recycled to provide water flow. The water outlet 10 can be connected to a filter tank or filtration device, and the filtered water flows back to the water source connected to the water inlet pipe 8 for recycling.
[0019] The nut outlet 9 is connected to an inclined spiral elevator 11, and the outlet of the spiral elevator 11 is connected to the second cleaning device 3. Nuts can be manually assisted into the spiral elevator 11 when necessary.

[0024] When using the nut washing and flotation equipment of this utility model:
[0025] Nuts are placed in the first cylinder 12, and water is introduced into the first cylinder 12 through the first water inlet pipe 29. The first servo motor 15 is started to stir and clean the nuts. Then, the first valve 13 is opened to let the nuts fall into the flotation tank 4. The nuts move forward with the water flow. Impurities with high buoyancy will pass through the first grid and be intercepted by the grid plate 7. Impurities with low buoyancy will pass through the second grid plate 6 and settle to the bottom of the water.
