Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to an egg washing pool. Background Technology

[0002] In the food processing industry, egg cleaning is a crucial step, especially for eggs like salted duck eggs that have a lot of dirt and sand on their surface. The efficiency and effectiveness of cleaning directly impact the quality of subsequent processing. Traditional egg cleaning equipment typically uses water rinsing or brush scrubbing to remove dirt from the egg surface through the impact of water or the mechanical friction of the brush. However, existing egg cleaning equipment has some drawbacks.

[0003] Existing cleaning equipment has limited effectiveness in removing stubborn mud and sand. During the pickling process of salted duck eggs, mud and sand often adhere tightly to the eggshell surface. Simply rinsing with water or scrubbing with a brush is insufficient to quickly and thoroughly separate the mud and sand, resulting in low cleaning efficiency and affecting subsequent cleaning steps. Broken eggshell fragments easily fall to the bottom of the cleaning tank, especially in inclined trough designs with drainage structures at the bottom. These fragments may be carried by the water flow into the drain outlet, causing pipe blockage or drainage system malfunctions, increasing maintenance difficulty. Existing equipment lacks an effective vibration mechanism during the cleaning process, failing to accelerate mud and sand removal through vibration. This results in a prolonged cleaning process and insufficient protection of the eggshells, easily leading to an increased egg breakage rate. Utility Model Content

[0004] In order to overcome the technical defects of existing technologies, such as low cleaning efficiency, difficulty in removing mud and sand, and easy clogging of the sewage system by eggshell fragments, this utility model provides an egg cleaning pool.

Overall, this egg cleaning tank significantly improves cleaning efficiency and effectiveness through the synergistic effect of vibration, brushing, and spraying, making it suitable for various egg processing scenarios.

Detailed Implementation

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] like Figures 1 to 7 As shown, the egg washing pool of this utility model includes:

[0033] The pool body 10 has a rectangular box structure and the bottom of the pool body 10 is inclined. The pool body 10 is supported by several legs. The upper part of the pool body 10 is provided with a liftable egg pressing grid 20. The lower end face of the grid 20 is provided with several cleaning brushes 21. The inner walls on both sides of the pool body 10 are provided with several longitudinal guide rails 13. The two sides of the grid 20 are provided with pulley groups 22 that cooperate with the several longitudinal guide rails 13.

[0034] A vibrating plate 30 is installed inside the pool body 10. The vibrating plate 30 has several through holes 31. The inner walls of both sides of the pool body 10 are provided with transverse slide rails 14 along the long axis of the pool body 10. The two opposite sides of the vibrating plate 30 are provided with sliding mechanisms 32 connected to the transverse slide rails 14 and move along the transverse slide rails 14. The bottom of the grid 20 and the vibrating plate 30 form an egg-containing space.

[0035] Motor 50 is fixed to the outer wall of pool body 10, and a transmission mechanism is provided at the connection between motor 50 and vibrating plate 30.

[0036] It also includes a sprinkler system 40, which includes a water pump 41, an inlet pipe 42, and a sprinkler pipe 43.

[0037] When the motor 50 and the spray system 40 are started, the vibrating plate 30 moves repeatedly along the transverse slide rail 14, and the grid 20 is pressed down above the vibrating plate 30, working in conjunction with the brushes of the spray system 40 and the grid 20 to clean the surface of the eggs.

[0038] This embodiment provides an egg washing pool, including a rectangular box-shaped pool body 10.

[0039] The pool body 10 is preferably welded or molded from corrosion-resistant materials such as stainless steel or engineering plastics. Its bottom is designed with a sloping structure, lower at the front and higher at the back, to facilitate the collection of detached waste into the lower-lying drain outlet 11211. The pool body 10 is supported by several adjustable legs at its bottom to adjust the overall tilt angle or working height of the pool body 10. The lowest point of the pool body 10 is provided with the drain outlet 11211, which is connected to a drain pipe. In this embodiment, a separate sludge discharge outlet 1122 can also be provided next to the drain outlet 11211 for discharging sediments such as sludge that are heavier than water.

[0040] The upper part of the pool body 10 is equipped with a liftable egg-pressing grid 20. The egg-pressing grid 20 has a rectangular frame structure, and its size is slightly smaller than the inner cavity of the pool body 10 to allow it to move up and down within the pool body 10. Several cleaning brushes 21 are fixedly installed on the lower end face of the egg-pressing grid 20. These brushes are preferably arranged parallel to each other along the length and width directions of the grid 20. The bristles of the brushes are preferably made of a soft and resilient polymer material, such as nylon or polypropylene, to effectively remove dirt from the surface of the eggs without damaging the eggshells. Several longitudinal guide rails 13 are provided on the inner walls of both sides of the pool body 10 along the height direction (i.e., the vertical direction). Pulley groups 22 that cooperate with the longitudinal guide rails 13 are provided at corresponding positions on the two sides of the egg-pressing grid 20. The egg-pressing grid 20 can be smoothly raised and lowered by the rolling of the pulley groups 22 on the longitudinal guide rails 13. The raising and lowering of the egg-pressing grid 20 can be achieved by an external drive mechanism.

[0041] Inside the pool body 10, below the egg pressing grid 20, a vibrating plate 30 is installed. The vibrating plate 30 is a rectangular perforated plate, preferably made of stainless steel, with dimensions matching the width of the pool body 10's inner cavity, and a length slightly less than the inner cavity length of the pool body 10, to allow reciprocating movement along the length direction (long axis direction) within the pool body 10. The vibrating plate 30 is densely covered with several through holes 31. These through holes 31 are preferably circular, with a diameter designed to allow mud and small eggshell fragments to pass through, but smaller than the size of the eggs to be cleaned, in order to hold the eggs. The diameter of the through holes 31 is preferably smaller than the minimum dimension of the egg's minor axis. Transverse slide rails 14 are provided on the inner walls of both sides of the pool body 10 along the long axis direction (i.e., horizontal direction). Sliding mechanisms 32 that cooperate with the transverse slide rails 14 are provided on the opposite two sides of the vibrating plate 30. The sliding mechanism 32 preferably includes sliders or rollers 321 fixed to the side of the vibrating plate 30, which are capable of sliding on the transverse slide rail 14 with low friction. Through the transverse slide rail 14 and the sliding mechanism 32, the vibrating plate 30 is constrained to reciprocate in the horizontal direction.

[0042] The bottom of the egg pressing grid 20 and the vibrating plate 30 form a holding space for placing eggs to be cleaned.

[0043] The cleaning tank also includes a spray system 40. The spray system 40 includes a water pump 41, an inlet pipe 42, and a spray pipe 43. The water pump 41 is connected to a water source outside the tank 10 or to a water circulation loop inside the tank 10, and delivers water to the spray pipe 43 via the inlet pipe 42. The spray pipe 43 is preferably positioned above the vibrating plate 30 and has multiple nozzles 431 facing the vibrating plate 30 and the eggs, used to spray and rinse the surface of the eggs, assisting the brush and reciprocating movement in removing dirt. The spray pipe 43 can also be positioned above the side of the vibrating plate 30, or the angle and distribution of the nozzles 431 can be adjusted according to actual cleaning needs.

[0044] like Figure 3 As shown, the motor 50 is fixed to the outer wall of the pool body 10. The motor 50 is connected to the vibrating plate 30 via a connecting mechanism. This connecting mechanism converts the rotational motion of the motor 50 into the reciprocating linear movement of the vibrating plate 30 along the transverse slide rail 14. The motor 50 is preferably a dustproof and waterproof type to adapt to the cleaning environment.

[0045] During operation, the eggs to be cleaned are placed on the vibrating plate 30. The water pump 41 and motor 50 are started, and the eggs are sprayed through the spray system 40. At the same time, the motor 50 drives the vibrating plate 30 to move back and forth repeatedly along the transverse slide rail 14. The egg pressing grid 20 can be lowered as needed, so that the brushes come into contact with the egg surface. Through the combined action of the brushes and the reciprocating movement of the vibrating plate 30, dirt and other impurities on the egg surface are efficiently removed. The loosened dirt, fine impurities and broken eggshells fall through the through holes 31 on the vibrating plate 30 onto the inclined surface at the bottom of the pool body 10, and are collected by the water flow to the drain outlet 11211, and discharged through the drain pipe.

[0046] The cleaning tank in this embodiment improves cleaning efficiency through the reciprocating movement of the vibrating plate 30 and the cooperation of the brush; the through hole 31 on the vibrating plate 30 effectively separates the washed mud and sand and fine impurities, preventing them from accumulating in the cleaning area; the inclined bottom of the tank and the drain outlet 11211 facilitate the centralized discharge of waste.

[0047] The above is only a preferred embodiment of this utility model. Those skilled in the art can make various modifications and variations without departing from the spirit of this utility model, and these modifications and variations should also be considered within the protection scope of this utility model. For example, the shape, size, and distribution of the through holes 31 in the vibrating plate 30 can be adjusted; the material, density, and arrangement of the brushes can be changed; the connecting mechanism driving the reciprocating movement can be a crank 521 connecting rod 522, an eccentric wheel connecting rod 522, a gear rack, a lead screw nut, etc.; the position of the spray pipe 43 and the type of nozzle 431 can be adjusted according to cleaning requirements, etc.

[0049] The spray system 40 includes a water pump 41, an inlet pipe 42 connecting the water pump 41 to the spray pipe 43, and the final spray pipe 43 for spraying. The water pump 41 is preferably a corrosion-resistant centrifugal pump, with its suction port connected to an external water source in the pool 10 and its outlet connected to the spray pipe 43 via the inlet pipe 42. The inlet pipe 42 is preferably made of rigid plastic or stainless steel, and its diameter and layout design ensure sufficient flow and pressure to reach the spray pipe 43.

[0050] The spray pipe 43 is the part that directly sprays and rinses the eggs. Depending on different cleaning requirements and the structure of the pool 10, the spray pipe 43 can be configured in various ways. In one embodiment, the spray pipe 43 includes a set of side spray pipes disposed on the side wall of the pool 10 and located between the vibrating plate 30 and the grid 20. These side spray pipes are provided with multiple nozzles 431 facing the vibrating plate 30 and the eggs for rinsing the eggs from the side. In another embodiment, or in combination with the side spray pipes, the spray pipe 43 may include a set of top spray pipes disposed above the vibrating plate 30. These top spray pipes are also provided with multiple nozzles 431 facing the vibrating plate 30 and the eggs for rinsing the eggs from above. These nozzles 431 are preferably fan-shaped nozzles 431 or conical nozzles 431, and their spray angle and flow rate can be selected according to cleaning requirements. They are evenly distributed or in a specific pattern along the length of the spray pipe 43 to ensure complete coverage of the egg surface on the vibrating plate 30.

[0051] Preferably, it also includes a conveyor belt 60 for conveying eggs, the conveyor belt 60 being inclinedly disposed at one end of the pool body 10, with its conveying end extending above or to one side of the vibrating plate 30.

[0052] The conveyor belt 60 is preferably an inclined roller conveyor belt 60, located at one end of the tank 10, for conveying the eggs to be cleaned into the cleaning area of ​​the next process. The conveyor belt 60 is located at the discharge end of the tank 10. Its receiving end is located at or below the end of the vibrating plate 30, for receiving the cleaned eggs discharged from the vibrating plate 30 or the discharge port of the tank 10. The conveyor belt 60 can be inclined (e.g., inclined upwards to lift the eggs to the height of the next process equipment) or horizontally, with its conveying end (i.e., discharge end) extending to the inlet position of the next fine washing process. The frame of the conveyor belt 60 is welded from metal profiles (such as stainless steel) and includes the conveyor belt and a motor 50 that drives the conveyor belt.

[0053] Preferably, the spray pipe 43 also includes a water storage pipe and a cleaning pipe, with the water storage pipe located at the top of the pool body 10 and the cleaning pipe located above the conveyor belt 60.

[0054] The water storage pipe is typically a horizontal pipe located at the top of the tank 10, connected to the main inlet pipe 42, and may have an overflow port or distribution hole. The water storage pipe functions as a buffer or distribution pipe, receiving water from the water pump 41 and distributing it to other branches of the spray pipes 43, or simply as a water level control and overflow structure at the top of the tank 10. The installation of the water storage pipe helps maintain stable water pressure in the spray system 40 or enables water flow management.

[0055] The washing pipe is a conduit positioned above the conveyor belt 60. This pipe also connects to a branch of the main water inlet pipe 42 or a water storage pipe of the spray system 40, and typically has multiple nozzles 431 or water outlets directed towards the washed eggs on the conveyor belt 60. The function of the washing pipe is to provide a final rinse or wash to the eggs leaving the washing tank and being conveyed on the conveyor belt 60, removing any residual foam or dirt before proceeding to the next fine washing process.

[0056] Preferably, the transverse slide rail 14 is a linear guide rail fixedly installed on the inner side wall of the pool body 10; the sliding mechanism 32 includes a roller 321 fixed to the side of the vibrating plate 30, and the roller 321 slides in cooperation with the linear guide rail.

[0057] like Figure 5 As shown, in order to enable the vibrating plate 30 to reciprocate along the long axis of the pool body 10 within the pool body 10, a transverse slide rail 14 and a sliding mechanism 32 are provided.

[0058] The transverse slide rail 14 is a linear guide rail fixedly installed on the inner wall of the pool body 10. The linear guide rail is preferably made of corrosion-resistant material, such as stainless steel or surface-treated metal guide rail, and is arranged parallel to the long axis of the pool body 10 at corresponding heights on both sides of the inner wall. The guide rail is securely fixed to the inner wall of the pool body 10 by bolts, welded brackets, or other means.

[0059] A sliding mechanism 32 is disposed on two opposite sides of the vibrating plate 30 and cooperates with a linear guide rail. The sliding mechanism 32 includes rollers 321 fixed to the sides of the vibrating plate 30. These rollers 321 preferably have bearings and are made of wear-resistant and corrosion-resistant materials (such as specific engineering plastics or stainless steel). The rollers 321 are fixed to the underside or side of the vibrating plate 30 by brackets or shafts. The rollers 321 contact or engage with the guide surface of the linear guide rail, allowing the vibrating plate 30 to slide smoothly horizontally along the direction of the linear guide rail with low frictional resistance. Through the transverse slide rail 14 composed of the linear guide rail and the rollers 321, and the sliding mechanism 32, the vibrating plate 30 is constrained to a horizontal movement trajectory.

[0060] Preferably, the transmission mechanism is a crank-connecting rod mechanism 52. The bottom of the vibrating plate 30 is provided with a connecting shaft 33. The output shaft of the motor 50 passes through the side wall of the pool body 10 and is connected to the crank-connecting rod mechanism 52. The crank-connecting rod mechanism 52 includes a crank 521 and a connecting rod 522. One end of the connecting rod 522 is provided with a connecting bearing 523, and the other end of the connecting rod 522 is hinged to the crank 521. The connecting bearing 523 is sleeved on the connecting shaft 33.

[0061] When the motor 50 starts, the crank 521 of the crank-connecting rod mechanism 52 drives the connecting rod 522 to move, causing the connecting rod 522 to rotate around the connecting shaft 33, thereby driving the connecting shaft 33 to move.

[0062] The motor 50 is fixed to the outer wall of the tank body 10. The output shaft of the motor 50 passes through the side wall of the tank body 10, and a sealing device is provided at the point where it passes through the side wall of the tank body 10 to prevent water from leaking out of the tank body 10. The sealing device preferably adopts a multi-stage sealing structure such as a mechanical seal or a corrosion-resistant oil seal to ensure long-term reliable operation.

[0063] A crank-connecting rod mechanism 52 is provided on the output shaft of the motor 50. This typically means that the crank 521 is directly fixed to the output shaft of the motor 50, or connected via a coupling. The crank-connecting rod mechanism 52 includes a crank 521 and a connecting rod 522. The crank 521 is a rotating component, and its radius of rotation determines the stroke of the connecting rod 522. The connecting rod 522 is a rigid rod that connects the crank 521 and the vibrating plate 30. The connecting rod 522 is preferably made of metal, and its length and strength are designed to withstand the push and pull forces required for transmission.

[0064] A connecting shaft 33 is provided at a corresponding position on the bottom of the vibrating plate 30. This connecting shaft 33 is fixed to the bottom structure of the vibrating plate 30 (e.g., fixed to a bracket or reinforcing rib) and serves as the pivot point for the connecting rod 522 connected to the vibrating plate 30. The connecting shaft 33 is preferably made of a corrosion-resistant material.

[0065] The connecting rod 522 of the crank-connecting rod mechanism 52 has one end hinged to the crank 521. This is typically a rotary joint achieved via a pin or similar means. The other end of the connecting rod 522 is provided with a connecting shaft 33 bearing, which is sleeved on the connecting shaft 33 at the bottom of the vibrating plate 30. This bearing-equipped connection forms the hinge point between the connecting rod 522 and the vibrating plate 30, allowing the connecting rod 522 itself to rotate around the connecting shaft 33 while pushing or pulling the vibrating plate 30 in reciprocating motion. The connecting shaft 33 bearing is preferably a self-lubricating or corrosion-resistant bearing with good sealing properties to adapt to the working environment.

[0066] When the motor 50 starts, its rotation drives the crank 521 to rotate around its axis. The rotation of the crank 521 is converted into a push-pull force through the connecting rod 522. The connecting rod 522 rotates (i.e., oscillates) around the connecting shaft 33 at the bottom of the vibrating plate 30. At the same time, since the connecting shaft 33 is constrained on the straight path of the transverse slide rail 14, the oscillation of the connecting rod 522 forces the connecting shaft 33 to move repeatedly in a straight line along the transverse slide rail 14, thereby driving the vibrating plate 30, which is fixed to the connecting shaft 33, to perform reciprocating linear motion along the transverse slide rail 14.

The vibrating plate 30 is densely covered with a plurality of circular through holes 31. The diameter of the through holes 31 is designed to allow mud, sand, and small eggshell fragments to pass through, while being smaller than the size of the eggs to support them. The distribution of the through holes 31 is preferably uniform to achieve a comprehensive screening effect.

[0069] like Figure 6 As shown, preferably, the grid 20 is a rectangular frame structure, the cleaning brush 21 is a soft brush, and the cleaning brush 21 is made of polypropylene material.

[0070] In this embodiment, the egg-pressing grid 20 located on the upper part of the pool body 10 is a rectangular frame structure, which can be raised and lowered via longitudinal guide rails 13 and pulley blocks 22. Several cleaning brushes 21 are fixedly installed on the lower end face of the grid 20. These brushes are preferably soft-bristled brushes, arranged parallel to each other along the length of the grid 20. The brush bristles are preferably made of polypropylene material, which has good flexibility and wear resistance, to effectively remove dirt from the egg surface without damaging the eggshell.

[0071] like Figures 1 to 3 As shown, preferably, a sludge discharge chamber 111 is provided at the bottom of the pool body 10 along the inclined surface of the bottom of the pool body 10. The sludge discharge chamber 111 is provided with a sludge discharge port 11211 connected to the pool body 10. The sludge discharge port 11211 includes a drain outlet 1121 and a sludge discharge outlet 1122. The drain outlet 1121 has a regulating valve 11211. Drainage pipes and sludge discharge pipes are connected to the sludge discharge port 11211 and the sludge discharge outlet 1122.

[0072] In this embodiment, in order to effectively manage the mud and dirt generated during the cleaning process, a sludge discharge chamber 111 is provided at the bottom of the pool body 10 along the inclined surface of the bottom of the pool body 10.

[0073] The sludge chamber 111 is typically a localized recess or water collection structure located at the lowest water-collecting area at the bottom of the pool body 10. It is used to temporarily collect silt, fine impurities, and wastewater that falls from the through-hole 31 of the vibrating plate 30 or is washed down by the water flow. The sludge chamber 111 is provided with a sludge outlet 11211, which connects to the main cleaning area inside the pool body 10, allowing waste to enter the sludge chamber 111. The sludge outlet 11211 includes a separate drain outlet 1121 and a sludge outlet 1122, both located at the bottom or side wall of the sludge chamber 111 to facilitate the discharge of collected liquid and solid waste.

[0074] The drain outlet 1121 is mainly used to discharge liquids during the cleaning process, and is usually located in a relatively high or easily accessible position within the drain chamber 111. The drain outlet 1121 is equipped with a regulating valve 11211, such as a gate valve, ball valve, or butterfly valve, to control the drainage flow or to completely shut off the drainage in order to maintain a certain water level during the cleaning process, or to quickly discharge wastewater all at once after cleaning.

[0075] The sludge discharge port 1122 is mainly used to discharge sludge and heavier impurities that have settled and accumulated in the sewage discharge chamber 111. The sludge discharge port 1122 is usually located at the lowest point of the sewage discharge chamber 111, and its opening size may be larger than that of the drain outlet 1121 to facilitate the smooth discharge of sludge. A valve may also be installed on the sludge discharge port 1122 to control the timing and flow rate of sludge discharge.

[0076] The drain outlet 1121 and the sludge discharge outlet 1122 on the sewage outlet 11211 are respectively connected to corresponding drainage pipes and sludge discharge pipes. These pipes transport the discharged liquid and solid impurities to an external treatment system or collection container. By independently setting up the drain outlet 1121 and the sludge discharge outlet 1122 and their pipes, different types of waste discharge can be managed more flexibly. For example, continuous overflow drainage can be carried out during the cleaning process, while the sludge and sand deposited at the bottom can be discharged in a concentrated manner after the cleaning is completed.

[0077] In summary, this embodiment provides a well-structured and highly efficient egg washing tank. The inclined bottom and sludge discharge chamber of the tank, combined with drainage and sludge discharge outlets, effectively manage waste discharge during the washing process. The reciprocating movement of the vibrating plates and the brushes of the grid, combined with the rinsing function of the spray system, achieve comprehensive cleaning of the egg surface. The conveyor belt and washing pipes further optimize egg transport and subsequent washing processes. This solution improves washing efficiency while ensuring the integrity of the eggs, making it suitable for the actual needs of the egg processing industry.

[0078] The working principle of the egg washing tank described in this utility model is as follows: Eggs to be washed are placed on a vibrating plate located inside the tank. They can be placed manually or fed continuously or in batches into the egg holding space above the vibrating plate via a conveyor belt located at one end of the tank. An appropriate amount of water is pre-filled into the tank. The egg-pressing grid is positioned and tightened, initially at the top. Depending on the washing requirements, the egg-pressing grid can be lowered, allowing the cleaning brushes fixed at its lower end to contact the surface of the eggs on the vibrating plate or apply a certain downward pressure. The grid moves smoothly on longitudinal guide rails on the inner walls of both sides of the tank via pulley sets on its sides; the downward pressure can be adjusted by a lifting mechanism. A motor fixed to the outer wall of the tank is started. The motor, through a crank-connecting rod mechanism and other connecting mechanisms, converts the rotational motion into reciprocating linear movement of the vibrating plate along the long axis (horizontal direction) of the tank. The vibrating plate slides repeatedly within a set stroke under the constraint of the transverse slide rails and sliding mechanism. A water pump is started, delivering clean water from an external water source to the spray pipes through the inlet pipe. The nozzles of the spray pipes spray clean water in a fan or cone shape onto the surface of the eggs moving on the vibrating plate. This helps to wet dirt, dissolve some contaminants, and provide the water's impact force to aid in cleaning. As the vibrating plate reciprocates, the eggs move along its surface. If the egg-pressing grid is pressed down, the eggs will be held or in contact between the brushes and the vibrating plate. The reciprocating movement of the vibrating plate creates relative friction and scrubbing between the egg surface and the relatively stationary (or pressurized) brushes. Stubborn dirt and grime are detached from the egg surface under the combined action of this mechanical force and water flow. The dirt, fine impurities (or broken eggshells) detached from the egg surface fall to the bottom of the tank through the holes in the vibrating plate. Larger pieces of dirt or broken eggshells may remain on the vibrating plate and be transported to one end with the reciprocating movement. Heavy objects such as dirt that fall to the bottom are collected along the sloping surface of the tank bottom by the water flow and drained into the lowest sludge bin. The silt and sand collected in the sludge discharge chamber can be discharged through the sludge discharge outlet. The outlet includes a drain outlet and a silt discharge outlet. During the cleaning process, overflow drainage is typically achieved by controlling the regulating valve on the drain outlet to maintain the water level in the tank. After cleaning, the silt discharge outlet (and its valve) is opened to collect and discharge the silt and sand deposited at the bottom, or it can be discharged periodically during the cleaning process. After the eggs are cleaned, the egg-pressing grid can be raised. Cleaned eggs can be removed manually or transported from the end of the vibrating plate to the conveyor belt at the discharge end of the tank, and then sent to the next fine washing process. Throughout the entire process, the reciprocating movement of the vibrating plate, the scrubbing action of the brushes, the rinsing of the spray liquid, and the design for guiding and discharging sludge at the bottom of the tank work together to form a continuous or batch egg cleaning and sludge management process.

Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
