Description

Technical Field

[0001] The invention belongs to the technical field of meatball production equipment and relates to a circulating water cooling device, in particular to a circulating water cooling device for meatball production. Background Art

[0002] The traditional production process of meatballs generally uses manual pounding and gelling technology as well as seasoning and ingredient preparation technology. It is made through multiple steps and has a unique taste.

[0003] During production, meatballs require rapid water cooling. Existing cooling processes suffer from inherent drawbacks and inefficiencies: Traditional water-cooling tanks rely on natural convection, resulting in long cooling times and a production bottleneck. Stacked meatballs in stagnant water tanks experience higher temperatures at the center than at the surface, leading to hardening, cracking, and microbial growth, resulting in a high defect rate. Furthermore, open water-cooling systems consume significant amounts of water daily, and direct steam discharge increases workshop humidity, indirectly increasing air conditioning energy consumption.

[0004] Based on this, we propose a circulating water cooling device for meatball production with good cooling effect and high efficiency. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a circulating water cooling device for meatball production. The technical problem to be solved by this invention is: how to achieve fast and stable efficient cooling of meatballs, while adopting a closed-loop water-gas dual circulation system for resources, fully recovering steam heat energy, saving water and reducing emissions.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A circulating water cooling device for ball production. The circulating water cooling device for ball production comprises a water-cooling trough and a cold water circulation mechanism located on the side of the water-cooling trough, wherein a plurality of filter boxes are provided at the lower end of the water-cooling trough, crawler conveyor mechanisms are provided at both ends of the water-cooling trough, and steam extraction mechanisms and spraying mechanisms are provided on the crawler conveyor mechanisms, a water injection mechanism and an aeration and pill turning mechanism are provided between one crawler conveyor mechanism and the water-cooling trough, a pill pressing mechanism and two rotating conveying mechanisms are provided inside the water-cooling trough, the pill pressing mechanism is located between the two rotating conveying mechanisms, a power assembly is provided on the side of the water-cooling trough, and the power assembly is connected to the pill pressing mechanism and the two rotating conveying mechanisms by transmission, the water-cooling trough and the plurality of filter boxes, the plurality of filter boxes and the cold water circulation mechanism, the cold water circulation mechanism and the water injection mechanism, the steam extraction mechanism and the spraying mechanism are all connected by water pipes, and the cold water circulation mechanism and the steam extraction mechanism, as well as the steam extraction mechanism and the aeration and pill turning mechanism are all connected by air pipes.

[0008] The working principle of the present invention is as follows: the power assembly drives the pellet pressing mechanism and the two rotating conveying mechanisms to move synchronously; the freshly cooked high-temperature pellets enter the water-cooling trough through the crawler conveying mechanism on the side of the feed end, and the hot air generated by the cold water circulation mechanism is introduced into the steam extraction mechanism. During transportation, the pellets first come into contact with the steam extraction mechanism at the feed end for air cooling (the air temperature is lower than the temperature of the pellets), and are then pre-cooled by cooling water sprayed by the spray mechanism;

[0009] When the balls enter the water-cooling trough, they will float on the water surface inside the water-cooling trough. At this time, the upper side of the water inside the water-cooling trough will be hotter. The rotating conveyor mechanism on the front side will press the balls into the water for a sinking and cooling process. The time is short and the cooling is fast. After the balls leave the rotating conveyor mechanism on the front side, they will continue to rise on the upper side of the water surface.

[0010] The pill pressing mechanism presses the pills into the water for a long period of secondary sinking and cooling. When the pills pass through the aeration and pill turning mechanism inside the water-cooling tank, the aeration and pill turning mechanism sprays air on the pills, and the cooling water is continuously stirred, causing the pills to tumble and rotate, ensuring faster cooling.

[0011] The cooling water absorbs the heat from the balls and heats up, with some of the water evaporating to produce steam. The heated water flows through the filter box to filter out impurities (such as starch and debris).

[0012] Then it is transported to the rotary conveyor mechanism at the rear side for three sinking and cooling. Finally, the balls are discharged and drained by the crawler conveyor mechanism at the discharge end. The balls are sprayed and cooled by the spray mechanism at the discharge end, while impurities are washed away. The balls are then dried with hot air by the steam extraction mechanism at the discharge end.

[0013] The water filtered by several filter boxes enters the cold water circulation mechanism and is cooled to the set temperature. Most of the cooled water is pumped to the water injection mechanism and re-injected into the water-cooling tank to maintain the water level and water flow; a small part is sent to the spray mechanism for surface pre-cooling;

[0014] The steam extraction mechanism extracts the steam generated on the inner surface of the water-cooling tank and the steam generated by the spray mechanism in the spray mode;

[0015] The steam extraction mechanism will generate water and hot air. The water will flow back to the cold water circulation mechanism for water cooling circulation, and the hot air will be fed into the aeration pill turning mechanism for aeration airflow circulation.

[0016] The water-cooling trough component includes a water-cooling trough bracket, a water-cooling trough body is provided on the water-cooling trough bracket, protective tubes are fixed on the left and right sides of the water-cooling trough body, a plurality of bearing seats are provided inside the protective tubes, and the two bearing seats facing each other on the left and right sides are symmetrically arranged, a plurality of waste buckets are provided at the lower end of the water-cooling trough body, and waste outlet connecting pipes are provided at the lower ends of the waste outlet buckets, and the waste outlet connecting pipes are respectively connected to the water inlet ends of the plurality of filter boxes through water connecting pipes, the front and rear ends of the water-cooling trough body are inclined, and a trough cover is provided at the upper end of the water-cooling trough body.

[0017] With the above structure, the water-cooling tank bracket firmly supports the water-cooling tank body, its upper mechanism, and the tank cover. The water-cooling tank body is the primary component for water cooling. The front and rear ends of the water-cooling tank body are tilted to accommodate the crawler conveyor mechanism. A removable and removable tank cover is installed on the top, forming a relatively enclosed space to reduce splashing of cooling water and disorderly diffusion of steam. Steam is mainly discharged by a steam extraction mechanism, which helps maintain a stable water temperature in the tank and also serves as a dust and pollution prevention mechanism. It can be opened periodically to remove floating impurities. A casing on one side is used to install the power assembly. The bearing seats are installed inside the casing. The bearing seats in the left and right casings are arranged in pairs and symmetrically. They are the key to the entire transmission support system and are used to install and secure the rotating conveyor mechanism and the shot pressing mechanism. The waste hopper is located at the lower end of the water-cooling tank body, with a large upper opening and a small lower opening. The waste discharge pipe is connected to the pipe at the lower opening of the waste discharge pipe and is used to collect and discharge impurities. The wastewater is discharged through the waste discharge pipe and enters the filter box through the water pipe, purifying the wastewater containing impurities instead of accumulating and polluting the water in the tank.

[0018] The rotating conveying mechanism includes a square rotating cylinder, the rotating shafts at the left and right ends of the square rotating cylinder respectively penetrate the water-cooling tank body, and the rotating shafts at the left and right ends of the square rotating cylinder are respectively fixed inside two bearing seats at corresponding positions that are symmetrical on the left and right. Each side of the square rotating cylinder is fixed with a number of equidistant and evenly distributed rotating pressure claws, and two driving sprockets are fixed on the rotating shaft of the square rotating cylinder on the same side as the power component.

[0019] With the above structure, the length of the square rotating cylinder matches the internal width of the water-cooling tank body. The two ends of the rotating shaft at the center position of the left and right ends of the square rotating cylinder pass through the openings on the side wall of the water-cooling tank body and are precisely installed in the bearing seats symmetrically opposite on the left and right sides (located in the casing), ensuring that the rotating cylinder can rotate stably and smoothly around the axis. The rotating shaft transmits power from the power component to the entire rotating conveying mechanism; the driving sprocket cooperates with the power component to provide power to drive the square rotating cylinder to rotate, and the rotating pressure claws are fixed on each side of the square rotating cylinder. The shape of the rotating pressure claws is usually designed to be L-shaped rods. The rotating pressure claws on the four sides rotate, which can effectively push the meatballs to sink into the water for cooling.

[0020] The pill pressing mechanism includes two pill pressing rollers, the left and right ends of the rotating shaft of the pill pressing rollers are fixed inside two bearing seats at corresponding positions on the left and right sides, and the left and right ends of the rotating shaft of the pill pressing rollers are fixed with two driving sprockets. Two side guide belts arranged symmetrically on the left and right sides are provided between the two pill pressing rollers, a pill pressing chain net is provided between the two side guide belts, and a number of evenly spaced material diverter plates are provided on the outside of the pill pressing chain net, and a number of evenly spaced material diverter rods are provided on the material diverter plates.

[0021] With the above structure, the balls float to the front feeding area of ​​the ball pressing mechanism, the power assembly drives the driving sprocket to rotate, the driving sprocket drives the two ball pressing frame rollers to rotate synchronously, the two ball pressing frame rollers drive the two side guide belts to move synchronously, and then drive the ball pressing chain network and several equidistant and evenly distributed stripping plates to move synchronously. Several stripping rods on the stripping plates press the balls down into the cold water, and the balls are transported to the crawler conveyor mechanism at the outlet end along with the ball pressing chain network, stripping plates and stripping rods, to ensure stable and efficient cooling of the balls.

[0022] The power assembly includes a drive motor, which is fixed inside the casing on one side. A drive sprocket is fixed on the output shaft of the drive motor, and a drive chain is provided between the drive sprockets at corresponding positions adjacent to each other.

[0023] With the above structure, the output shaft of the driving motor drives the driving sprocket to rotate, and the driving sprockets at corresponding positions adjacent to each other are sequentially driven by the driving chain to ensure stable operation of the rotating conveying mechanism and the pill pressing mechanism.

[0024] The crawler conveyor mechanism includes an inlet and outlet conveying bracket, an inwardly inclined water collecting bottom trough plate and two symmetrically arranged conveying side plate frames are fixed at the upper end of the inlet and outlet conveying bracket, a number of conveying shafts are rotatably arranged between the two conveying side plate frames, a perforated conveying crawler is provided between the several conveying shafts, a number of equidistant and evenly distributed scraper plates are provided on the perforated conveying crawler, the end of the water collecting bottom trough plate is located above the water cooling tank body, the horizontal section of the perforated conveying crawler is located at the upper end of the water collecting bottom trough plate, and the inclined section of the perforated conveying crawler is located above the water cooling tank body, an electric control box is provided on the side of the inlet and outlet conveying bracket of one of the crawler conveyor mechanisms, a conveying motor is fixed on the side of the inlet and outlet conveying bracket, the output shaft of the conveying motor is transmission-connected to one of the conveying shafts, and a shot guide plate is fixed on the inner end of each conveying side plate frame.

[0025] With the above structure, the working process at the inlet end is as follows: the high-temperature meatballs are transported from the upstream aging equipment and fall into the horizontal section of the perforated conveyor belt. The spray mechanism sprays cooling water on the high-temperature meatballs on the belt for preliminary cooling and flushing; the output shaft of the conveying motor drives one of the conveying shafts to rotate, and several conveying shafts cooperate with the perforated conveyor belt to drive the perforated conveyor belt to run. The scraper plate pushes the meatballs along the inclined section of the perforated conveyor belt, and then is smoothly guided into the water-cooling tank body through the ball guide plate. The spray water and the moisture brought in by the meatballs pass through the through holes of the perforated conveyor belt and quickly drip onto the inclined water collecting bottom trough plate below, guiding the water away and discharging it into the water-cooling tank body; at the highest point of the inclined section, located above the water-cooling tank body, the meatballs slide off the conveyor belt and fall into the water of the water-cooling tank body, officially starting the cooling process.

[0026] Working process at the outlet end: The rotary conveying mechanism at the outlet end sends the cooled and water-pressed balls out of the water surface. The balls are smoothly guided to the inclined section (the inclined section plays a receiving role at this time) or horizontal section of the perforated conveyor belt by the ball guide plate. The conveying motor drives the perforated conveyor belt to run, and the scraper plate pushes the balls away from the water cooling tank. The small amount of water remaining on the surface of the balls continues to drip through the perforated belt to the water collecting bottom trough plate below, where it is collected and discharged into the water cooling tank body. The balls are driven out by the horizontal section of the perforated conveyor belt, and the balls leave the perforated conveyor belt and enter the next process.

[0027] The electronic control box dynamically adjusts parameters to meet the different physical properties of fish balls, meatballs, etc.

[0028] The water injection mechanism includes a water guide pipe, a protective cover, a water injection pump, a water outlet pipe, a built-in main pipe and several equidistant water addition pipes. The protective cover and the water injection pump are fixed inside the inlet and outlet conveying brackets of one of the crawler conveyor mechanisms. The water injection pump is located inside the protective cover. One end of the water guide pipe is connected to the water inlet end of the water injection pump, and one end of the water outlet pipe is connected to the water outlet end of the water injection pump. The built-in main pipe and several equidistant water addition pipes are all fixed on the inner bottom side of the water cooling tank body and located above the waste outlet bucket. The water addition pipe is connected to the built-in main pipe, and the built-in main pipe is connected to the other end of the water outlet pipe. The water addition pipe is provided with several water injection nozzles with the water outlet direction upward.

[0029] With the above structure, the low-temperature circulating water cooled and filtered and purified by the cold water circulation mechanism is introduced into the water injection pump located inside the inlet and outlet conveying bracket through the water guide pipe; the water injection pump is started to pressurize the cooling water and pump it to the built-in main pipe installed on the bottom side of the water-cooling tank body through the outlet pipe; the water flow is distributed from the built-in main pipe to several equidistant and evenly distributed water supply pipes, and the cooling water is sprayed upward to the bottom of the water-cooling tank body through the water injection nozzles on the water supply pipes to replenish cold water; the water injection nozzle is located above the waste hopper, ensuring that the water flow will not violently stir the impurities deposited in the waste hopper at a lower position, thereby maintaining the cleanliness of the water quality; the protective cover is used to protect the water injection pump.

[0030] The aeration pill turning mechanism includes an aeration mesh pipe and an air blower. The air blower is fixed inside the inlet and outlet conveying bracket of one of the crawler conveyor mechanisms. A plurality of mounting gussets are provided on the left and right sides of the aeration mesh pipe. The plurality of mounting gussets are arranged on the left and right inner walls of the water-cooling tank body. The lower end of the aeration mesh pipe is provided with a plurality of aeration nozzles arranged in an array with an exhaust direction downward and evenly distributed. The lower end of the aeration mesh pipe is provided with an air inlet joint. An air injection pipe is provided between the air inlet joint and the exhaust end of the air blower. The aeration mesh pipe is located between the two pill pressing rack rollers, and the aeration nozzle is located on the upper side of the pill pressing chain mesh below.

[0031] With the above structure, the air blower is started to generate compressed air, which is transported to the air inlet joint of the aeration network pipe through the air injection pipe. The air flows in the aeration network pipe and is evenly distributed to the aeration nozzles arrayed at its lower end. The compressed air passes through the aeration nozzles and is sprayed into the water in a downward direction. Since the exhaust direction is downward, the gas is first forced into the deep water to form bubbles, which impact on the balls and force them to turn over. The stacked balls will be completely broken up, and the stuck balls will be forcibly separated, so that they are in full contact with the water and cooled stably and quickly. The bubbles that have completed the turning task will eventually float to the surface and may be extracted by the steam extraction mechanism or dissipate naturally.

[0032] The steam extraction mechanism includes a water collecting box, an air inlet oven, and two water filtering fans symmetrically arranged on the left and right sides. The water collecting box is fixed inside the inlet and outlet conveying bracket, the air inlet oven is fixed on the upper ends of the two conveying side plate frames, and the air inlet oven is located directly above the horizontal section of the perforated conveying crawler. The two water filtering fans are respectively fixed on the left and right sides of the two conveying side plate frames. The two water filtering fans are directly opposite to the horizontal section of the perforated conveying crawler. The water filtering outlet of the water filtering fan is connected to the water collecting box by a water connecting pipe, and the air outlet end of the water filtering fan is connected to the air inlet end of the air blower by an air pipe.

[0033] With the above structure, the high-temperature balls fall on the horizontal section of the conveyor belt with holes at the inlet end. The balls emit a lot of heat, and the spray mechanism may spray cooling water. This process generates a large amount of high-temperature, high-humidity steam and hot air. The air inlet oven is shrouded above the belt, blowing the generated wet steam and hot air downward. The two symmetrical water filter fans are started to generate suction, and the collected high-temperature wet steam and hot air are sucked into the water filter fan. The wet steam is inside the water filter fan, and the liquid water (condensed water) is separated and discharged into the water collecting tank through the water filter outlet and the water connecting pipe. It is collected and the relatively dry hot air is separated and discharged from the air outlet. It is transported to the air inlet end of the air blower through the air pipe, forming an air circulation.

[0034] The spray mechanism includes a spray water pump and two spray main pipes. The spray water pump is fixed inside the inlet and outlet conveying bracket. The water inlet end of the spray water pump is connected to a filter. The filter and the filter box are connected by a pipe. The two spray main pipes are respectively fixed at the upper end of the conveying side plate frame at the corresponding position. The two spray water pipes are located at the upper end of the inclined section of the perforated conveying crawler. A spray water pipe is provided between one of the spray main pipes and the water outlet pipe of the spray water pump. Several equidistant and evenly distributed spray branches connected to the two spray main pipes are fixed between them, and several spray nozzles are provided on the spray branches.

[0035] With the above structure, the circulating cooling water that has been preliminarily purified by the filter box is introduced into the filter through a pipe, and is finally finely filtered by the filter to remove tiny impurities that may clog the nozzle; the filtered clean cooling water enters the water inlet end of the spray water pump for pressurized transportation; the pressurized water is transported to one of the spray main pipes through the spray water pipe, and the water flows from the first spray main pipe to the spray branch pipe connected to it, and then flows to the other spray main pipe through the spray branch pipe to ensure uniform water pressure in the entire spray frame; the water flows in the spray branch pipe network, and the water flows through the spray nozzle and is converted into a designed spray water flow (fan-shaped, conical or mist-shaped), which is evenly covered on the perforated conveyor crawler passing below and the high-temperature balls it carries, for pre-cooling and flushing, and the water flow washes away surface impurities; the large amount of steam generated by the spray is processed by the steam extraction mechanism.

[0036] The cold water circulation mechanism includes a cold water circulation rack, and a water pump, a water storage tank, a cold injection pump and a water storage tank are sequentially arranged on the front and back of the lower inner side of the cold water circulation rack, and two symmetrically arranged condensers are provided on the upper inner side of the cold water circulation rack. A plurality of induced draft fans are provided on the upper end of the cold water circulation rack, and the induced draft fans are located directly above the condensers. The air outlet end of the induced draft fan is connected to the air inlet end of the air inlet oven through an air pipe, the water inlet end of the water pump is connected to the filter box through a water connecting pipe, the water outlet end of the water pump is connected to the water storage tank through a water pipe, the water inlet end of the cold injection pump is connected to the water storage tank and the water collecting tank through a water pipe, and a hot water exchange pipe is provided between the water inlet end of the cold injection pump and the water storage tank, and the hot water exchange pipe passes through the two condensers, and the other end of the water guide pipe is connected to the water storage tank through a water pipe.

[0037] With the above structure, the water pump extracts the main circulating cooling water that has been physically filtered but has a higher temperature (absorbed the heat of the balls) from the filter box. The heated water is pumped into the water storage tank for buffering, pressure stabilization and secondary sedimentation. The cold injection pump recovers condensed water from the water storage tank and the water collection tank. At the same time, it extracts water from the mixed water source and pressurizes it; the pressurized mixed heated water is forced to be pumped through the two condensers through the heat exchange pipe. In the condenser, the heat of the water is efficiently transferred to the refrigerant (air cooling: refrigerant evaporation absorbs heat; water cooling: chilled water); the cooled low-temperature water enters the water storage tank for storage to stabilize the temperature and pressure; main water injection: most of the low-temperature water is supplied to the water injection mechanism through the water pipe, It is injected into the bottom of the water-cooling tank to push the balls and maintain the low temperature and water level in the tank; spray water: a part of the low-temperature water is supplied to the spray mechanism for pre-cooling and rinsing the balls; the induced draft fan is started, generating a strong downward airflow, vertically sweeping the heat dissipation fins of the condenser, and taking away the heat released by the condenser; the heated air (waste heat) is discharged from the air outlet of the induced draft fan and transported to the air inlet end of the air inlet oven through the air pipe. The air inlet oven blows the hot air to the moisture of the balls, reduces the condensation of steam in the oven, and maintains the chamber temperature; the condensed water in the water collection tank of the steam extraction mechanism is extracted by the cooling pump and mixed into the main circulating water for cooling and reuse, reducing the amount of fresh water added to the system.

[0038] Compared with the existing technology, the circulating water cooling device for meatball production has the following advantages:

[0039] The water-gas dual circulation system is adopted to achieve nearly zero waste of resources. The steam extraction mechanism and the aeration and pill turning mechanism cooperate to fully recover the steam heat energy and separate it into aeration and pill turning power and drying hot air.

[0040] The water-cooling tank, filter box, water injection mechanism and cold water circulation mechanism are coordinated, as well as the cold water circulation mechanism and spray mechanism. After multi-stage filtration, most of the spray wastewater, impurity water in the tank and condensed water can be reused, with a high water saving rate;

[0041] The three-stage immersion + pneumatic pill turning design uses a power assembly that works with the rotary conveying mechanism and the pill pressing mechanism. The three-stage pressing extends the cooling path, and the steam extraction mechanism and the aeration pill turning mechanism spray downward to create turbulence, which increases the pill turning frequency and shortens the cooling time.

[0042] The water injection nozzle is designed to be downward to avoid sediment in the waste bucket, and the spray system filter is prevented from clogging; the symmetrical bearing seat in the casing is waterproof and sealed, and the double sprocket drive disperses the load, extending the transmission life and reducing maintenance frequency;

[0043] The water-cooling trough and two crawler conveyor mechanisms cooperate to form a pipeline-type conveying system with high adaptability and production capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

A water injection mechanism 3 and an aeration and ball turning mechanism 11 are provided between one of the crawler conveyor mechanisms 5 and the water-cooling trough 1. A ball pressing mechanism 9 and two rotating conveying mechanisms 8 are provided inside the water-cooling trough 1. The ball pressing mechanism 9 is located at the bottom of the water-cooling trough 1. Between the two rotating conveying mechanisms 8, a power component 10 is provided on the side of the water-cooling trough 1. The power component 10 is connected to the pill pressing mechanism 9 and the two rotating conveying mechanisms 8 through transmission. The water-cooling trough 1 and the plurality of filter boxes 2, the plurality of filter boxes 2 and the cold water circulation mechanism 7, the cold water circulation mechanism 7 and the water injection mechanism 3, the steam extraction mechanism 4 and the spraying mechanism 6 are all connected through water pipes. The cold water circulation mechanism 7 and the steam extraction mechanism 4, as well as the steam extraction mechanism 4 and the aeration pill turning mechanism 11 are all connected through air pipes.

[0057] The power assembly 10 drives the pellet pressing mechanism 9 and the two rotating conveying mechanisms 8 to move synchronously; the hot meatballs just cooked enter the water-cooling trough 1 through the crawler conveying mechanism 5 on the side of the feed end. The hot air generated by the cold water circulation mechanism 7 is introduced into the steam extraction mechanism 4. During transportation, the meatballs first come into contact with the steam extraction mechanism 4 at the feed end for air cooling (the air temperature is lower than the temperature of the meatballs), and are pre-cooled by the cooling water sprayed by the spray mechanism 6;

[0058] When the balls enter the water-cooled trough 1, they will float on the water surface inside the water-cooled trough 1. At this time, the upper side of the water inside the water-cooled trough 1 will be hotter. The front rotating conveyor mechanism 8 will press the balls into the water for a sinking and cooling process. The time is short and the cooling process is fast. After the balls leave the front rotating conveyor mechanism 8, they will continue to rise on the upper side of the water surface.

[0059] The pill pressing mechanism 9 presses the pills into the water for a long period of secondary sinking and cooling. When the pills pass through the aeration pill turning mechanism 11 inside the water-cooling tank 1, the aeration pill turning mechanism 11 sprays the pills, the cooling water is continuously stirred, and the pills roll and rotate, ensuring faster cooling.

[0060] The cooling water absorbs the heat from the balls and heats up, and some of the water evaporates to produce steam; the heated water flows through the filter box 2 to filter out impurities (such as starch and debris);

[0061] Then it is transported to the rear rotary conveyor mechanism 8 for three sinking cooling, and finally the ball is discharged by the crawler conveyor mechanism 5 at the discharge end and drained, and sprayed by the spray mechanism 6 at the discharge end for cooling, while washing away impurities, and the ball is dried by the steam extraction mechanism 4 at the discharge end with hot air;

[0062] The water filtered by several filter boxes 2 enters the cold water circulation mechanism 7 and is cooled to the set temperature. Most of the cooled water is pumped to the water injection mechanism 3 and re-injected into the water-cooling tank 1 to maintain the water level and water flow; a small part is sent to the spray mechanism 6 for surface pre-cooling;

[0063] The steam extraction mechanism 4 extracts the steam generated on the inner surface of the water-cooling tank 1 and the steam generated in the spraying mode by the spraying mechanism 6;

[0064] The steam extraction mechanism 4 generates water and hot air. The water flows back to the cold water circulation mechanism 7 for water cooling recycling, and the hot air is fed into the aeration pill turning mechanism 11 for aeration airflow recycling.

[0065] The water-cooling trough component 1 includes a water-cooling trough bracket 13, on which a water-cooling trough body 12 is provided. Casings 23 are fixed on the left and right sides of the water-cooling trough body 12, and a number of bearing seats 32 are provided inside the casing 23. The two bearing seats 32 facing each other on the left and right sides are symmetrically arranged.

[0074] The working process at the inlet end is as follows: the high-temperature meatballs are transported from the upstream aging equipment and fall into the horizontal section of the perforated conveyor belt 50. The spray mechanism 6 sprays cooling water on the high-temperature meatballs on the belt for preliminary cooling and rinsing; the output shaft of the conveying motor 52 drives one of the conveying shafts 49 to rotate, and the plurality of conveying shafts 49 cooperate with the perforated conveyor belt 50 to drive the perforated conveyor belt 50 to run. The scraper plate 51 pushes the meatballs along the inclined section of the perforated conveyor belt 50, and then is smoothly guided into the water-cooling tank body 12 through the ball guide plate 46. The spray water and the moisture brought in by the meatballs pass through the through holes of the perforated conveyor belt 50 and quickly drip onto the inclined water collecting bottom trough plate 53 below, which guides the water away and discharges it into the water-cooling tank body 12; at the highest point of the inclined section, located above the water-cooling tank body 12, the meatballs slide off the conveyor belt and fall into the water of the water-cooling tank body 12, officially starting the cooling process.

The conveying motor 52 drives the perforated conveyor belt 50 to run, and the scraper plate 51 pushes the meatballs away from the water-cooling tank. The small amount of water remaining on the surface of the meatballs continues to drip through the perforated belt to the water collecting bottom trough plate 53 below, where it is collected and discharged into the water-cooling tank body 12. The meatballs are driven out by the horizontal section of the perforated conveyor belt 50, and the meatballs leave the perforated conveyor belt 50 and enter the next process.

[0079] The aeration pill turning mechanism 11 includes an aeration mesh tube 34 and an air blower 48. The air blower 48 is fixed inside the inlet and outlet conveying bracket 38 of one of the crawler conveyor mechanisms 5. A number of mounting clips 35 are provided on the left and right sides of the aeration mesh tube 34. The number of mounting clips 35 are arranged on the left and right inner walls of the water-cooling tank body 12.

[0080] The air blower 48 is started to generate compressed air, which is transported to the air inlet connector 37 of the aeration network pipe 34 through the air injection pipe. The air flows in the aeration network pipe 34 and is evenly distributed to the aeration nozzles 36 arrayed at its lower end. The compressed air is sprayed into the water in a downward direction through the aeration nozzles 36. Since the exhaust direction is downward, the gas is first forced to be pressed into the deep water, forming bubbles, which impact on the meatballs and force them to turn over. The stacked meatballs will be completely broken up, and the sticky meatballs will be forcibly separated, so that they are in full contact with the water and cooled stably and quickly. The bubbles that have completed the turning task eventually float to the surface of the water and may be extracted by the steam extraction mechanism 4 or dissipate naturally.

[0081] The steam extraction mechanism 4 includes a water collecting box 39, an air inlet oven 42, and two water filtering fans 40 symmetrically arranged on the left and right. The water collecting box 39 is fixed inside the inlet and outlet conveying bracket 38, and the air inlet oven 42 is fixed on the upper end of the two conveying side plate frames 54, and the air inlet oven 42 is located directly above the horizontal section of the perforated conveying belt 50.

[0082] The high-temperature meatballs fall on the horizontal section of the conveyor belt 50 with holes at the inlet end. The meatballs emit a lot of heat, and the spray mechanism 6 may spray cooling water. This process generates a large amount of high-temperature, high-humidity steam and hot air. The air inlet oven 42 is shrouded above the belt, blowing the generated wet steam and hot air downward. The two symmetrical water filter fans 40 are started to generate suction, and the collected high-temperature wet steam and hot air are sucked into the water filter fans 40. The wet steam is inside the water filter fans 40, and the liquid water (condensed water) is separated and discharged into the water collecting tank 39 through the water filter outlet and the water connecting pipe. It is collected and the relatively dry hot air is separated and discharged from the air outlet. It is transported to the air inlet end of the air blower 48 through the air pipe, forming an air circulation.

[0083] The spray mechanism 6 includes a spray water pump 56 and two spray main pipes 44. The spray water pump 56 is fixed inside the inlet and outlet conveying bracket 38. The water inlet end of the spray water pump 56 is connected to the filter 55. The filter 55 is connected to the filter box 2 through a pipe. The two spray main pipes 44 are respectively fixed at the upper ends of the conveying side plate frames 54 at corresponding positions. The two spray water pipes 43 are located at the upper ends of the inclined sections of the perforated conveying crawlers 50. A spray water pipe 43 is provided between one of the spray main pipes 44 and the water outlet pipe of the spray water pump 56. Several equidistant and evenly distributed spray branches 45 connected thereto are fixed between the two spray main pipes 44, and several spray nozzles 47 are provided on the spray branches 45.

[0084] The circulating cooling water that has been preliminarily purified by the filter box 2 is introduced into the filter 55 through a pipeline, and is finally finely filtered by the filter 55 to remove tiny impurities that may clog the nozzle; the filtered clean cooling water enters the water inlet end of the spray water pump 56 for pressurized transportation; the pressurized water is transported to one of the spray main pipes 44 through the spray water pipe 43, and the water flows from the first spray main pipe 44 to the spray branch pipe 45 connected to it, and then flows to the other spray main pipe 44 through the spray branch pipe 45 to ensure uniform water pressure in the entire spray frame; the water flows in the spray branch pipe 45 network, and the water flows through the spray nozzle 47, and is converted into a designed spray water flow (fan-shaped, conical or mist-shaped), which is evenly covered on the perforated conveyor crawler 50 passing below and the high-temperature meatballs it carries, for pre-cooling and flushing, and the water flow washes away surface impurities; the spraying generates a large amount of steam, which is processed by the steam extraction mechanism 4.

[0085] The cold water circulation mechanism 7 includes a cold water circulation frame 57. The lower side of the cold water circulation frame 57 is provided with a water pump 60, a water storage tank 61, a cold injection pump 62 and a water storage tank 63 in sequence. The upper side of the cold water circulation frame 57 is provided with two symmetrically arranged condensers 58. The upper end of the cold water circulation frame 57 is provided with a plurality of induced draft fans 59. The induced draft fans 59 are located just above the condensers 58. The air outlet end of the induced draft fans 59 is connected to the air inlet end of the air inlet oven 42 through an air pipe. The water inlet of the water pump 60 is connected to the filter box 2 through a water connecting pipe, the water outlet of the water pump 60 is connected to the water storage tank 61 through a water pipe, the water inlet of the cold injection pump 62 is connected to the water storage tank 61 and the water collecting tank 39 through a water pipe, and a hot water exchange pipe is provided between the water inlet of the cold injection pump 62 and the water storage tank 63. The hot water exchange pipe passes through two condensers 58, and the other end of the water guide pipe 27 is connected to the water storage tank 63 through a water pipe.

[0086] The water pump 60 extracts the main circulating cooling water that has been physically filtered but has a higher temperature (absorbed the heat of the meatballs) from the filter box 2. The heated water is pumped into the water storage tank 61 for buffering, pressure stabilization and secondary sedimentation. The cold injection pump 62 recovers condensed water from the water storage tank 61 and the water collection tank 39. At the same time, it extracts water from the mixed water source and pressurizes it; the pressurized mixed heated water is forced to be pumped through the two condensers 58 through the heat exchange pipe. In the condenser 58, the heat of the water is efficiently transferred to the refrigerant (air cooling: refrigerant evaporation absorbs heat; water cooling: chilled water); the cooled low-temperature water enters the water storage tank 63 for storage to stabilize the temperature and pressure; main water injection: most of the low-temperature water is supplied to the water injection mechanism 3 through the water pipe 27 and is injected The heated air (waste heat) is discharged from the outlet of the induced draft fan 59 and transported to the inlet of the air inlet oven 42 through the air pipe. The air inlet oven 42 blows the hot air to remove moisture from the meatballs, reduce steam condensation in the oven, and maintain the chamber temperature. The condensed water in the water collecting tank 39 of the steam extraction mechanism 4 is extracted by the cold injection pump 62 and mixed into the main circulating water for cooling and reuse, thus reducing the amount of fresh water added to the system.

[0087] Working principle of the present invention:

[0088] Ingress preprocessing:

[0089] Hot meatball input: Freshly cooked meatballs are fed in sequentially via the perforated conveyor belt 50 of the crawler conveyor mechanism 5 at the entrance, with the scraper 51 preventing accumulation;

[0090] Spray pre-cooling: The spray mechanism 6 extracts low-temperature water from the cold water circulation mechanism 7 through the precision filter 55, and sprays it through the spray nozzle 47 to cover the surface of the meatballs, achieving two-step cooling:

[0091] In the horizontal section, the air inlet oven 42 blows air downwards for initial air cooling; in the inclined section, the spray mechanism 6 sprays to form a primary water cooling and flush impurities;

[0092] Steam extraction and drainage: The steam generated by the spraying is blown downward by the air inlet oven 42, and the remaining water drips into the inclined water collecting bottom trough plate 53 through the track holes and is guided back into the interior of the water cooling tank body 12.

[0093] Three-stage cooling of water cooling tank:

[0094] First-stage cooling (front rotary conveyor mechanism 8), after the meatballs enter the water and float on the water surface, the rotating pressing claws 14 of the square rotating cylinder 15 press them underwater, quickly reducing the surface temperature;

[0095] Secondary cooling (pill pressing mechanism 9 + aeration pill turning mechanism 11): the pills float to the pill pressing chain net 33, and the material rod 31 turns them to prevent stacking.

[0096] Aeration and ball turning linkage: The hot air recovered by the steam extraction mechanism 4 is pressurized by the air blower 48 and sprayed downward from the aeration nozzle 36. The bubbles float up to form turbulence, forcing the balls to turn (mechanical + pneumatic dual turning), improving cooling efficiency; continuous immersion cooling.

[0097] Three-stage cooling (rear rotary conveyor mechanism 8): The balls are pressed into water again to consolidate and cool down, while moving towards the exit.

[0098] Export drying:

[0099] The cooled balls are lifted by the perforated conveyor belt 50 of the crawler conveyor mechanism 5 at the outlet and sent out in sequence; the waste heat is recovered for drying, and the waste heat of the condenser 58 of the cold water circulation mechanism 7 is introduced into the air inlet oven 42 through the induced draft fan 59 and blown to the balls for hot air drying.

[0100] Water-air dual circulation system:

[0101] Water circulation closed loop, water collection: the heated water in the tank flows through the waste hopper 16 to discharge impurities (starch / debris), filtration: the impure water enters the filter box 2 for filtration;

[0102] Cooling: The water pump 60 pumps water to the water storage tank 61 for buffering sedimentation;

[0103] The cold injection pump 62 mixes the extracted steam condensate (from the water collection tank 39) and pumps it into the condenser 58 for cooling;

[0104] Reuse: cold water is stored in the water tank 63 and supplied to the water injection mechanism 3 to inject into the tank bottom (downward spray head to avoid slag), and part of it is supplied to the spray mechanism 6;

[0105] Air circulation closed loop: Steam extraction: The water filter fan 40 extracts steam and separates it into: condensed water → merged into the cold water circulation, dry hot air → supplied to the aeration pill turning mechanism as air source;

[0106] Waste heat recovery: The heat dissipated air from the condenser 58 is introduced into the air inlet oven 42 by the induced draft fan 59 to realize heat energy utilization.

[0107] In summary, the device adopts a water-gas dual circulation system to achieve nearly zero resource waste. The steam extraction mechanism 4 and the aeration and pill turning mechanism 11 cooperate to fully recover the steam heat energy and separate it into aeration and pill turning power and drying hot air.

[0108] The water-cooling tank 1, the filter box 2, the water injection mechanism 3 and the cold water circulation mechanism 7 cooperate with each other, and the cold water circulation mechanism 7 and the spray mechanism 6 cooperate with each other. After multi-stage filtration, the spray wastewater, the impurity water in the tank and the condensed water can be mostly reused, with a high water saving rate;

[0109] The three-stage immersion + pneumatic pill turning design uses a power assembly 10 that cooperates with the rotary conveying mechanism 8 and the pill pressing mechanism 9. The three-stage pressing extends the cooling path. The steam extraction mechanism 4 and the aeration pill turning mechanism spray downward to create turbulence, which increases the pill turning frequency and shortens the cooling time.

[0110] The water injection nozzle is designed to be downward to avoid sediment in the waste bucket 16, and the spray system filter 55 is blocked. The symmetrical bearing seat 32 in the casing 23 is waterproof and sealed, and the dual sprocket drive disperses the load, extending the transmission life and reducing maintenance frequency.

[0111] The water-cooling trough 1 and the two crawler conveyor mechanisms 5 cooperate to form a pipeline-type conveying system with high adaptability and production capacity.

[0112] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
