Description

Technical Field

[0001] This utility model belongs to the field of egg processing equipment, and specifically relates to a centrifuge for egg processing. Background Technology

[0002] The production of salted duck eggs involves screening, cleaning, soaking in white wine, and curing in mud. After curing, the mud on the surface of the duck eggs is cleaned, and then the eggs are sorted again. The salted duck eggs are then cracked open, and the yolks and egg whites are separated in a centrifuge. The separated yolks need to be cleaned and baked before final grading and packaging. Currently, during the process of cracking the eggshells and separating the yolks and egg whites, tiny eggshell fragments are easily mixed into the yolks and egg whites. The existing solution is to manually inspect the yolks after centrifugation and remove any remaining eggshell fragments. This method is not only labor-intensive and resource-intensive, leading to low efficiency, but also prone to worker fatigue after long hours, resulting in incomplete removal of eggshell fragments.

[0003] Therefore, a centrifuge for egg processing is needed. Utility Model Content

[0004] The purpose of this invention is to provide a centrifuge for egg processing, thereby overcoming the defect in the existing salted duck egg yolk production process where manual sorting of eggshell fragments is required after centrifugation to separate the yolk and egg liquid. The specific technical solution is as follows:

[0005] A centrifuge for egg processing includes a centrifuge body, a base, a hydraulic cylinder, a support plate, a first motor, a coupling, a support frame, a rotating shaft, a top cover, a support tube, a first filter screen, a second motor, and a second filter screen. The base is installed on one side of the centrifuge body. The hydraulic cylinder is vertically installed inside the base and faces upwards. The support plate is installed on the output end of the hydraulic cylinder. The support frame is installed on the support plate. The rotating shaft is rotatably installed on the support frame. The first motor is installed on the support plate. The output end of the first motor is connected to one end of the rotating shaft via a coupling. The top cover is rotatably connected to the rotating shaft. One end of the support tube is connected to the side of the top cover facing the centrifuge. The first filter screen is installed on the other end of the support tube. The second motor is installed on the side of the top cover away from the support tube. The output end of the second motor passes through the top cover and is located inside the support tube. The second filter screen is installed on the output end of the second motor and is in contact with the first filter screen. The first and second filter screens have the same mesh size, filter holes, and diameter.

[0006] Preferably, the filter holes on the first filter screen are funnel-shaped, and the diameter of the filter hole at the end closest to the second filter screen is smaller than that at the other end.

[0007] Preferably, the edge of the filter hole away from the second filter screen has a rounded corner.

[0008] Preferably, a drain valve is installed on the inner wall of the support tube, the drain valve is located on the side of the support tube near the rotating shaft, and a drain pipe is installed on the base, one end of the drain pipe is vertically upward, and when the top cover is perpendicular to the horizontal plane, the valve port of the drain valve is coaxial with the drain pipe.

[0009] Preferably, the sewage pipe is provided with a connecting plate, the connecting plate is provided with an arc-shaped groove, the diameter of the arc-shaped groove is equal to the diameter of the outer wall of the support pipe, and a sealing ring is installed on the connecting plate.

[0010] Preferably, the support tube is made of transparent material, and the support tube is connected to the top cover using a quick-release structure.

[0011] Preferably, the upper cover has multiple water spray holes on the side near the first filter screen, and a water distribution chamber is provided inside the upper cover. The water spray holes are connected to the water distribution chamber, and one end of the water distribution chamber is connected to a water supply pipe. The other end of the water supply pipe is connected to a water pump.

[0012] Preferably, a guide plate is installed inside the support tube, with both ends of the guide plate connected to the inner sidewall of the support tube. The guide plate is attached to the upper cover and the second filter screen. The guide plate has a through hole connected to the drain valve. When the upper cover is perpendicular to the horizontal plane, the guide plate is in a horizontal state.

[0013] Compared with existing technologies, this utility model has the following beneficial effects:

[0014] 1. This utility model utilizes a first and second filter screen in conjunction. When the top cover moves downwards, it carries the first and second filters and the support tube into the centrifuge body. The liquid inside the centrifuge gradually submerges the first and second filters. The first filter screen prevents egg yolk from entering the support tube, while eggshell fragments are carried by the water flow through the filter holes into the support tube and float on the surface. When the top cover descends to the designated position, the second motor starts, rotating the second filter screen. This causes the first and second filters to become decoaxial, reducing the size of the filter holes on the first filter screen until eggshell fragments can no longer pass through. At this point, hydraulic pressure moves the top cover upwards, allowing the liquid in the support tube to flow out through the filter holes, while the eggshell fragments remain in the support tube and are collected. Compared to existing manual eggshell fragment picking methods, this application not only reduces manpower and resources and improves work efficiency but also ensures a stable screening effect for eggshell fragments, thereby guaranteeing product quality.

[0015] 2. This utility model utilizes a drain valve in conjunction with a water spray nozzle. After the liquid in the support pipe is discharged, the second motor starts, driving the second filter screen to completely seal the filter holes of the first filter screen. Then, the first motor drives the upper cover to rotate to a vertical position, and the hydraulic cylinder moves the support plate down until the connecting plate is in contact with the support pipe. Afterward, the drain valve is opened, and the water pump is started, spraying clean water from the water spray nozzle to clean the second and first filter screens, discharging the wastewater and eggshell fragments through the drain pipe. This application automates the cleaning of eggshells by automatically cleaning the second and first filter screens, thereby further improving work efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0025] A centrifuge for egg processing, reference Figures 1 to 4 .

[0026] The base 2 is bolted to one side of the centrifuge body 1. The hydraulic cylinder 3 is bolted vertically into the base 2 with its moving end facing upwards. The support plate 4 is bolted to the output end of the hydraulic cylinder 3. The support frame 7 is welded to the support plate 4, and the rotating shaft 8 is rotatably mounted on the support frame 7. The first motor 5 is bolted to the support plate 4. The output end of the first motor 5 is connected to one end of the rotating shaft 8 via a coupling 6. The upper cover 9 is rotatably connected to the rotating shaft 8. One end of the support tube 10 is connected to the side of the upper cover 9 facing the centrifuge, and the first filter screen 11 is installed at the other end of the support tube 10. The second motor 13 is bolted to the side of the upper cover 9 away from the support tube 10. The output end of the second motor passes through the upper cover 9 and is located inside the support tube 10. The second filter screen 12 is installed on the output end of the second motor 13 and fits against the first filter screen 11. The edge of the first filter screen 11 fits against the inner wall of the support tube 10. The mesh count, filter holes, and diameter of the first filter screen 11 and the second filter screen 12 are the same. In the initial state, the filter holes on the first filter screen 11 and the filter holes on the second filter screen 12 correspond one-to-one and are coaxial. The hydraulic cylinder 3, the first motor 5, and the second motor 13 are all controlled by a controller.

[0027] After the operator places the peeled egg yolks and egg liquid into the centrifuge, adds an appropriate amount of water, and then starts the centrifuge to separate the egg liquid and yolks. After the centrifuge has been running for a period of time, the controller activates hydraulic cylinder 3. The output end of hydraulic cylinder 3 drives support plate 4 to move upward to a designated position. Then, the first motor 5 starts, driving shaft 8 to rotate 90 degrees through coupling 6. The upper cover 9 rotates 90 degrees synchronously, making support tube 10 coaxial with the material cylinder on the centrifuge, and the outer diameter of support tube 10 is 1-2 cm smaller than the inner diameter of the material cylinder. Afterward, hydraulic cylinder 3 drives support plate 4 to descend, thereby driving upper cover 9 to descend synchronously. When upper cover 9 moves downward, it drives the first filter, second filter screen 12, and support tube 10 into the centrifuge body 1. The liquid in the centrifuge will gradually submerge the first and second filters. The first filter screen 11 prevents egg yolk from entering the support tube 10. Because the area of ​​the filter holes in the first filter screen 11 is only 1 / 3 to 2 / 3 of the total area of ​​the first filter screen 11, the space formed between the support tube 10 and the first filter screen 11 will compress the liquid in the barrel. Under the action of air pressure, the liquid in the barrel will pass through the filter holes and flow into the support tube 10. Eggshell fragments will follow the water flow under strong water pressure, pass through the filter holes, enter the support tube 10, and float on the water surface. The water pressure at the filter holes also facilitates the eggshell fragments to pass through the filter holes more easily, avoiding jamming.

[0028] Once the top cover 9 descends to the designated position, the second motor 13 starts, driving the second filter screen 12 to rotate. This causes the first filter screen 11 and the second filter screen 12 to become decoaxial, thereby reducing the size of the filter holes on the first filter screen 11 until eggshell fragments can no longer pass through. At this point, hydraulic pressure causes the top cover 9 to move upward, and the liquid in the support tube 10 flows out from the filter holes, while the eggshell fragments remain in the support tube 10 and are collected. Compared to existing manual eggshell fragment picking methods, this application not only reduces manpower and material resources and improves work efficiency, but also ensures a stable screening effect for eggshell fragments, thereby guaranteeing product quality.

[0029] The filter holes on the first filter screen 11 are funnel-shaped, with the diameter of the end of the filter hole closer to the second filter screen 12 being smaller than that of the other end. The funnel shape can further increase the flow rate and water pressure, thereby preventing eggshell fragments from getting stuck. The edge of the filter hole away from the second filter screen 12 is rounded, which can prevent the filter screen from damaging the egg yolk while filtering the yolk, thus ensuring the integrity of the egg yolk.

[0030] A drain valve is installed on the inner wall of the support pipe 10. The drain valve is a solenoid valve and is controlled by a controller. The drain valve is located on the side of the support pipe 10 near the rotating shaft 8. A drain pipe 16 is installed on the base 2. One end of the drain pipe 16 is vertically upward. When the upper cover 9 is perpendicular to the horizontal plane, the valve port of the drain valve is coaxial with the drain pipe 16. A connecting plate 17 is provided on the drain pipe. The connecting plate 17 has an arc-shaped groove with a diameter equal to the diameter of the outer wall of the support pipe 10. A sealing ring is installed on the connecting plate 17 to prevent sewage leakage. Multiple water spray holes are opened on the side of the upper cover 9 near the first filter screen 11. A water distribution chamber is opened inside the upper cover 9. The water spray holes are connected to the water distribution chamber. One end of the water supply pipe is connected to the water distribution chamber, and the other end of the water supply pipe is connected to a water pump.

[0031] After the liquid in the support tube 10 is drained, the second motor 13 starts, driving the second filter screen 12 to completely seal the filter holes of the first filter screen 11. Then, the first motor 5 drives the upper cover 9 to rotate to a vertical position, and the hydraulic cylinder 3 drives the support plate 4 to move down until the connecting plate 17 is in contact with the support tube 10. After that, the drain valve is opened and the water pump is started, and the water spray nozzle sprays clean water to clean the second filter screen 12 and the first filter screen 11, and the sewage and eggshell fragments are discharged through the drain pipe 16. This application automates the eggshell cleaning process by automatically cleaning the second filter screen 12 and the first filter screen 11, thereby further improving work efficiency. After the filter screens are cleaned, the support tube 10 remains in contact with the connecting plate 17 to drain, and the controller starts the second motor 13 to move the second filter screen 12 to a position coaxial with the filter holes of the first filter screen 11.

[0032] The support tube 10 is made of transparent material, allowing operators to easily observe the filtration process and decide whether to repeat the filtration. The support tube 10 is connected to the top cover 9 using a quick-release mechanism, and the support tube 10 and the first filter screen 11 can be removed for maintenance.

[0033] A guide plate 14 is installed inside the support tube 10. Both ends of the guide plate 14 are connected to the inner wall of the support tube 10. The guide plate 14 is fitted to the upper cover 9 and the second filter screen 12. A through hole 15 is provided on the guide plate 14 and is connected to the drain valve. When the upper cover 9 is perpendicular to the horizontal plane, the guide plate 14 is horizontal. The guide plate 14 completely isolates the drain valve, thus preventing sewage and eggshell fragments from accumulating in the gap between the drain valve and the support tube 10.

[0034] Furthermore, the guide plate 14 can be made into an arc shape, with the inner sidewall of the guide plate 14 facing the second motor 13. The arc surface of the arc plate can facilitate the better flow of sewage and eggshell fragments to the drain valve.
