Description

Technical Field

[0001] This invention relates to the field of flotation separation technology, and more specifically to an agricultural product sorting device based on flotation separation. Background Technology

[0002] Sinking-float separation is a technology based on the difference in material density. Its principle is to separate the components in a mixture by using a liquid or gaseous medium, where the denser components sink and the less dense components float. Eggs are the most common agricultural product and a common raw material in food production and processing. Food production often requires large quantities of eggs, and in these large quantities, inferior eggs are often mixed with good quality eggs, making them difficult to distinguish. In actual food processing, methods such as visual inspection and light transmission are commonly used to screen eggs. However, these methods require constant adjustment of the egg's position for inspection, making the process cumbersome, inefficient, and inaccurate. Furthermore, eggshells are often covered with chicken droppings and other dirt, requiring manual cleaning to avoid damaging the eggs, which incurs significant labor costs. Therefore, we propose a sinking-float separation-based agricultural product sorting device to solve these problems. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an agricultural product sorting device based on sinking and floating separation to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an agricultural product sorting device based on flotation and buoyancy separation, comprising a flotation and buoyancy assembly, wherein the flotation and buoyancy assembly comprises a separation liquid tank, wherein a premium product outlet pipe is fixedly connected to the bottom end of the front side of the separation liquid tank, and a premium product screening assembly is rotatably sleeved on the bottom end of the inner side of the separation liquid tank.

[0005] A mounting circular plate is fixedly connected to the top of the separation liquid tank. A feed plate is fixedly connected to the top of the mounting circular plate. A vertical track plate is fixedly connected to one end of the feed plate. A directional conveying component is fixedly connected to one end of the vertical track plate. Three defective track plates are fixedly connected to the inner wall of the top of the separation liquid tank. A connecting plate is fixedly connected to one end of each of the three defective track plates. One end of each of the three connecting plates is fixedly connected to a ring guide rail.

[0006] The vortex in the separation tank, combined with the inferior product track plate, drives the superior product screening component to rotate and connect to the superior product outlet pipe to sort eggs. The upright track plate causes the eggs to fall upright into the directional conveying component for all-round cleaning.

[0007] Furthermore, an attitude fixing component is fixedly connected to the top of the floating and sinking component, and a defective product screening component is fixedly connected to the side of the top of the floating and sinking component.

[0008] Furthermore, a workbench is fixedly connected to the bottom of the separation tank, and vertical plates are fixedly connected to both ends of the top of the workbench. A horizontal plate is fixedly connected to the top of the two vertical plates, and a motor is fixedly connected to the top of the horizontal plate. A rotating rod is rotatably connected to the bottom of the motor, and the rotating rod passes through the horizontal plate. An agitator is fixedly connected to the bottom end of the rotating rod.

[0009] Furthermore, a disc is fixedly connected to the bottom of the stirring drum, and the premium product screening component includes an annular guide rail. The side of the annular guide rail is provided with a slot, and four sails are fixedly connected to the inner side of the annular guide rail. The annular guide rail is rotatably sleeved on the bottom end of the inner side of the separation liquid tank.

[0010] Furthermore, the rotation angle of the annular guide rail inside the separation liquid tank is 0-45°, the annular guide rail can only rotate towards the outlet of the premium product pipeline, and when the annular guide rail rotates 45°, the groove corresponds to the outlet of the premium product pipeline.

[0011] Furthermore, the attitude fixing component includes a feeding plate, the back of which is fixedly connected to the front of a vertical plate, and the feeding plate is inclined at an angle of 15°-25° to the horizontal plane.

[0012] Furthermore, a mounting circular plate is fixedly sleeved on the side of the directional conveying assembly. The mounting circular plate has a rectangular groove. One end of the feed plate and the bottom of the vertical track plate are fixedly connected to the rectangular groove. Three short rods are fixedly connected to the bottom of the mounting circular plate, and the bottom ends of the three short rods are fixedly connected to the top of the separation liquid tank.

[0013] Furthermore, the directional conveying assembly includes a central shaft, which is connected to the rotating rod via a transmission assembly. Mounting plates are rotatably fitted onto the side of the top end and the side of the bottom end of the central shaft.

[0014] Furthermore, constraint plates are fixedly connected to both sides of the two mounting plates. One side of the constraint plate is provided with an arc-shaped groove, and a brush is fixedly sleeved on the side of the central shaft. The constraint plate is located between the two mounting plates.

[0015] Furthermore, the defective product screening component includes a second annular guide rail, the inner side of which is provided with three square openings, and each of the three square openings is fixedly connected to a connecting plate. One end of the defective product rail plate is bent downwards, and the bending angle is 15°-35°.

[0016] The technical effects and advantages of this invention are as follows:

[0017] Eggs are placed on the feeding plate and rolled onto the vertical track plate. Under the action of the vertical track plate, the eggs stand upright and fall into two constraint plates. The motor drives the rotating rod to rotate, and under the action of the transmission component, the central shaft also begins to rotate. As the eggs fall between the two constraint plates, the central shaft carries the brush to sweep the eggs horizontally. While the eggs fall vertically, they rotate under the action of the horizontal friction of the brush, so that the brush cleans the eggshell from all directions, avoiding manual cleaning of the eggs and saving a lot of labor costs.

[0018] A liquid of a specific density is injected into the separation tank. Eggs fall into the water from the constraint plate. The motor drives the rotating rod to rotate, which in turn drives the stirring drum to rotate. Under the action of the stirring drum, the water in the separation tank forms a vortex, stratifying in the dynamic liquid flow: high-density, high-quality eggs sink to the premium screening component, while low-density, inferior eggs float and are guided by the inferior quality track plate to the second annular guide rail, achieving continuous wet sorting. Under the centrifugal force of the vortex, the eggs make a circular motion along the inner wall of the separation tank. Because the eggs of poor quality float on the surface, they move along... As the inner wall of the separation tank moves, the inferior eggs are guided to the second annular guide rail and detached from the water surface. After the inferior eggs are detached from the water surface, the total mass of water in the separation tank decreases, and the vortex generated by the stirring drum becomes stronger. This causes the vortex water flow to push the sail plate to move, thereby rotating the first annular guide rail until the slot aligns with the outlet pipe for superior eggs. The water in the separation tank is then discharged from the outlet pipe for superior eggs, and the superior eggs are discharged with the water flow. This achieves the separation of superior and inferior eggs, solving the problems of complicated processes and low efficiency in traditional separation methods. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The agricultural product sorting device based on sinking and floating separation involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1 The present invention provides an agricultural product sorting device based on sinking and floating separation, including a sinking and floating component 1, a posture fixing component 2 fixedly connected to the top of the sinking and floating component 1, and a defective product screening component 3 fixedly connected to the side of the top of the sinking and floating component 1.

[0029] In this embodiment, it is necessary to further explain that the floating and sinking component 1 and the attitude fixing component 2 avoid manual cleaning of eggs, saving a lot of labor costs. The floating and sinking component 1 and the defective product screening component 3 solve the problems of complicated process and low efficiency of traditional screening methods. The specific structure and working principle of the above components will be explained in detail later.

[0030] Reference Figure 2 The flotation and sinking assembly 1 includes a separation liquid tank 101. The bottom of the front of the separation liquid tank 101 is fixedly connected to a premium product outlet pipe 102. A workbench is fixedly connected to the bottom of the separation liquid tank 101. Vertical plates are fixedly connected to both ends of the top of the workbench. A horizontal plate is fixedly connected to the top of the two vertical plates. A motor 103 is fixedly connected to the top of the horizontal plate. A rotating rod 104 is rotatably connected to the bottom of the motor 103 and passes through the horizontal plate. An agitating drum 105 is fixedly connected to the bottom of the rotating rod 104.

[0031] In this embodiment, it should be specifically noted that the separation liquid tank 101 contains brine with a density of 1.05-1.10 g / cm³, which is suitable for the density differences of eggs. The bottom of the premium product outlet pipe 102 is equipped with a drain trough. When the water in the separation liquid tank 101 is discharged from the premium product outlet pipe 102, the drain trough discharges some water, reducing the water pressure flowing through the premium product outlet pipe 102 and preventing excessive water pressure from damaging the eggs.

[0032] Reference Figure 3 The bottom of the stirring drum 105 is fixedly connected to a disc, and the bottom of the inner side of the separation liquid tank 101 is rotatably sleeved with a premium screening component 106.

[0033] Reference Figure 4 The premium product screening component 106 includes an annular guide rail 1061, which has a slot on its side. Four sails 1062 are fixedly connected to the inner side of the annular guide rail 1061. The annular guide rail 1061 is rotatably sleeved on the bottom of the inner side of the separation liquid tank 101. The rotation angle of the annular guide rail 1061 inside the separation liquid tank 101 is 0-45°. The annular guide rail 1061 can only rotate towards the opening of the premium product outlet pipe 102.

[0034] In this embodiment, it should be specifically explained that when the annular guide rail 1061 rotates 45°, the slot corresponds to the outlet of the premium product outlet pipe 102, the four sails are evenly distributed at 90° with an inclination angle of 15°, forming an axial-radial composite flow field, which promotes the movement of light impurities towards the barrel wall.

[0035] Reference Figure 5 The attitude fixing component 2 includes a feed plate 201. The back of the feed plate 201 is fixedly connected to the front of a vertical plate. The feed plate 201 is inclined at an angle of 15°-25° to the horizontal plane. A vertical track plate 202 is fixedly connected to one end of the feed plate 201. A directional conveying component 203 is fixedly connected to one end of the vertical track plate 202. An installation circular plate 204 is fixedly sleeved on the side of the directional conveying component 203. The installation circular plate 204 is provided with a rectangular groove. One end of the feed plate 201 and the bottom of the vertical track plate 202 are both fixedly connected to the rectangular groove. Three short rods are fixedly connected to the bottom of the installation circular plate 204. The bottom ends of the three short rods are fixedly connected to the top of the separation liquid tank 101.

[0036] In this embodiment, it is necessary to further explain that the inclination angle of the feed plate 201 to the horizontal plane is 15°-25°, preferably 25°, for optimal egg rolling efficiency. The two ends of the vertical track plate 202 are angled upwards and perpendicular to the horizontal plane. When the egg passes through the vertical track plate 202, it enters the water with its air chamber facing upwards, avoiding air bubble adhesion that could affect separation. The distance between the outlet of the vertical track plate 202 and the liquid surface is controlled at 50-80mm, and the egg's entry angle is 80°-85° (relative to the horizontal plane). This angle aligns the egg's axis with the water flow direction, reducing air bubble adhesion (measured residual air bubble area <2%).

[0037] Reference Figure 6 The directional conveying assembly 203 includes a central shaft 2031, which is connected to the rotating rod 104 via a transmission assembly. Mounting plates are rotatably sleeved on the side of the top end and the side of the bottom end of the central shaft 2031. Constraint plates 2033 are fixedly connected to both sides of the two mounting plates. An arc-shaped groove is provided on one side of the constraint plate 2033. A brush 2032 is fixedly sleeved on the side of the central shaft 2031. The constraint plate 2033 is located between the two mounting plates.

[0038] The 2032 brush uses nylon 612 bristles with a diameter of 0.15mm and a tensile strength of ≥800MPa. The bristles are arranged in a spiral shape (8mm pitch) with a density of 1200 bristles / cm², ensuring full coverage of the egg surface (curvature radius adapted to 40-45mm egg shape). The contact pressure between the brush and the egg is dynamically adjusted by a pre-compression spring mechanism (range 5-15N), with real-time feedback from a pressure sensor. The cleaning force can be controlled between 0.3-0.5MPa, effectively removing dirt without damaging the eggshell membrane.

[0039] Eggs are placed on the feeding plate 201 and roll from the feeding plate 201 into the vertical track plate 202. Under the action of the vertical track plate 202, the eggs stand upright and fall into the two constraint plates 2033. The motor 103 drives the rotating rod 104 to rotate. Under the action of the transmission component, the central shaft 2031 also starts to rotate. As the eggs fall between the two central shafts 2031, the central shafts 2031 carry the brushes 2032 to sweep the eggs horizontally. While the eggs fall vertically, they rotate under the action of the horizontal friction of the brushes 2032, so that the brushes 2032 clean the egg shell from all directions, avoiding manual cleaning of eggs and saving a lot of labor costs.

[0040] In this embodiment, it should be specifically noted that the transmission component is a chain, which is existing technology and therefore will not be described in detail.

[0041] Reference Figure 7The defective product screening component 3 includes an annular guide rail 301. The inner side of the annular guide rail 301 is provided with three square openings. Each of the three square openings is fixedly connected to a connecting plate 302. One end of each of the three connecting plates 302 is fixedly connected to a defective product track piece 303. The sides of the three defective product track pieces 303 are fixedly sleeved on the inner wall of the top of the separation liquid tank 101. One end of the defective product track piece 303 is bent downwards, and the bending angle is 15°-35°.

[0042] In this embodiment, it should be specifically noted that one end of the inferior track piece 303 is bent downward at 25°.

[0043] In the separation tank 101, a liquid of a specific density (such as brine) is added. Eggs fall into the water from the constraint plate 2033. The motor 103 drives the rotating rod 104 to rotate, which in turn drives the stirring drum 105 to rotate. Under the action of the stirring drum 105, the water in the separation tank 101 forms a vortex, and the eggs separate into layers in the dynamic liquid flow: high-density, high-quality eggs sink to the premium screening component 106, while low-density, inferior eggs float and are guided by the inferior quality track plate 303 to the annular guide rail 301, realizing continuous wet sorting. Under the centrifugal force of the vortex, the eggs make a circular motion along the inner wall of the separation tank 101. Due to the poor quality of the eggs, they float to the top. As the eggs move along the inner wall of the separating liquid tank 101, they are guided by the inferior quality track plate 303 to the second annular guide rail 301 and detach from the water surface. After the inferior quality eggs are detached from the water surface, the total mass of the water in the separating liquid tank 101 decreases, and the stirring drum 105 generates a stronger vortex. This causes the vortex water flow to push the sail plate 1062 to move, thereby causing the first annular guide rail 1061 to rotate until the trough aligns with the superior quality outlet pipe 102. The water in the separating liquid tank 101 is then discharged from the superior quality outlet pipe, and the superior quality eggs are discharged with the water flow. This achieves the separation of superior quality eggs from inferior quality eggs, solving the problems of complicated processes and low efficiency in traditional separation methods.

[0044] The working principle of this invention is as follows: An egg is placed in the feeding plate 201 and rolls from the feeding plate 201 into the vertical track plate 202. Under the action of the vertical track plate 202, the egg stands upright and falls into the two constraint plates 2033. The motor 103 drives the rotating rod 104 to rotate. Under the action of the transmission component, the central shaft 2031 also starts to rotate. As the egg falls between the two central shafts 2031, the central shaft 2031 carries the brush 2032 to sweep the egg horizontally. While the egg falls vertically, it rotates under the action of the horizontal friction of the brush 2032, so that the brush 2032 cleans the egg shell in all directions, avoiding manual cleaning of the egg and saving a lot of labor costs.

[0045] In the separation tank 101, a liquid of a specific density is used. Eggs fall into the water from the constraint plate 2033. The motor 103 drives the rotating rod 104 to rotate, which in turn drives the stirring drum 105 to rotate. Under the action of the stirring drum 105, the water in the separation tank 101 forms a vortex, and the eggs are separated into layers in the dynamic liquid flow: high-density, high-quality eggs sink to the premium screening component 106, while low-density, inferior eggs float and are guided by the inferior quality track plate 303 to the annular guide rail 301, realizing continuous wet sorting. Under the centrifugal force of the vortex, the eggs make a circular motion along the inner wall of the separation tank 101. Due to the poor quality, the eggs float to the surface. As the eggs move along the inner wall of the separating liquid tank 101, they are guided by the inferior quality track plate 303 to the second annular guide rail 301 and detached from the water surface. After the inferior quality eggs are detached from the water surface, the total mass of water in the separating liquid tank 101 decreases, and the stirring drum 105 generates a stronger vortex. This causes the vortex water flow to push the sail plate 1062 to move, thereby causing the first annular guide rail 1061 to rotate until the slot aligns with the superior quality outlet pipe 102. The water in the separating liquid tank 101 is then discharged from the superior quality outlet pipe, and the superior quality eggs are discharged with the water flow. This achieves the separation of superior quality eggs from inferior quality eggs, solving the problems of complicated processes and low efficiency in traditional sieving methods.
