Description

Technical Field

[0001] The present invention relates to the field of cooling water circulation, and particularly to a fermentation tank for recycling cooling water in a circulating manner. Background Art

[0002] During the fermentation process of a fermentation tank, a large amount of heat is generated. If the cooling is poor, it will cause the death of fermentation bacteria and affect the fermentation effect.

[0003] For the cooling of existing fermentation tanks, generally, cold water sources are directly used to cool the fermentation tanks, and the cooling water is directly discharged, resulting in serious waste of water resources. Or a simple water circulation is carried out using a water storage tank. When carrying out the water circulation of the cooling water, on the one hand, the circulating cooling water will cause the temperature to increase when cooling the fermentation tank, resulting in an impact on the cooling effect. On the other hand, water continuously volatilizes during the cooling process of the circulating cooling water, resulting in a gradual increase in the concentration of salt substances in the remaining cooling water. When the concentration of these salt substances exceeds their solubility, scale will form on the surfaces of equipment such as heat exchangers and pipelines. The formation of scale will not only greatly reduce the heat transfer efficiency, increase the energy consumption of the equipment, but also may cause local overheating of the equipment, affecting the normal operation of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and a fermentation tank for recycling cooling water in a circulating manner is proposed.

[0005] The present invention provides a fermentation tank for recycling cooling water in a circulating manner, including a tank body. The tank body includes a feeding pipe and a discharging pipe, and further includes:

[0006] A cooling cylinder, inserted through the middle of the tank body;

[0007] A water tank, fixed to the bottom of the cooling cylinder;

[0008] A cooling pipe, arranged in a spiral shape inside the tank body. One end of the cooling pipe extends through the inside of the cooling cylinder, and the other end is located inside the water tank and is fixed with a water pump;

[0009] A circulating cooling component, installed inside the cooling cylinder, for cooling the cooling water discharged from the cooling pipe through air flow and then making it fall into the water tank to form a cycle;

[0010] An air flow guiding component, installed outside the tank body, for guiding and condensing the air flow used for cooling by the circulating cooling component to recover the moisture carried in the air flow, and conveying the air flow into the inside of the water tank to drive the cooling water to fluctuate;

[0011] When the fermenter needs to be cooled, the water pump is started. After the water pump starts, it drives the cooling water inside the water tank to flow along the cooling pipe. The cooling pipe spirally passes through the inside of the tank body, so as to cool the inside of the tank body when the cooling water passes through. Subsequently, the cooling water is transported along the cooling pipe to the circulating cooling component. The circulating cooling component is inside the cooling cylinder and cools the cooling water flowing through the cooling pipe, so that the temperature of the cooling water drops and then returns to the inside of the water tank again. This is conducive to avoiding the situation that the cooling water gradually heats up during the cooling process, thereby affecting the cooling effect of the cooling water on the inside of the tank body;

[0012] The circulating cooling component cools the heated cooling water through air flow. When the air flow passes through the cooling water, a large amount of water is carried away. At this time, the air flow is guided into the air flow guiding component, so that the air flow cools down when passing through the air flow guiding component, and the water contained in the air flow precipitates under the action of condensation. The precipitated water flows back to the cooling cylinder or enters the water tank along the air flow guiding component. This is conducive to reducing the escape of water. And the flowing air flow enters the water tank after passing through the air flow guiding component and is discharged from below the water surface of the water tank. The discharged air flow impacts the cooling water inside the water tank, making the water flow inside the water tank flow, which is conducive to driving the cooling water inside the water tank to further cool down, and is conducive to avoiding the situation that the cooling water heats up during the cooling process and affects the cooling effect.

[0013] Preferably, the circulating cooling component includes:

[0014] A fixed pipe, fixed inside the cooling cylinder, and one end of the cooling pipe extending into the cooling cylinder is fixedly communicated with the fixed pipe;

[0015] Multiple nozzles, fixedly installed at the bottom of the fixed pipe in a linear array, for spraying the cooling water entering the inside of the fixed pipe;

[0016] An air flow chamber, fixedly communicated with the top of the cooling cylinder;

[0017] A first driving fan, fixedly installed inside the air flow chamber;

[0018] The cooling water flows along the cooling pipe into the inside of the fixed pipe, and then sprays out from the nozzles at the bottom of the fixed pipe. At the same time, the first driving fan drives the air flow to flow upward along the cooling cylinder. The air flow flowing to the cooling cylinder enters from the outside along the surface of the water tank and into the bottom of the cooling cylinder. When the air flow passes through the inside of the cooling cylinder, it passes through the cooling water sprayed out from the nozzles. At this time, the contact area between the sprayed cooling water and the air flow increases, so that the cooling effect of the air flow on the cooling water increases, which is conducive to cooling the cooling water. The cooled cooling water falls into the inside of the water tank, which is conducive to avoiding the situation that the cooling water affects the cooling effect after heating up.

[0019] Preferably, the air flow guiding assembly includes:

[0020] An air flow guiding pipe, fixed to the outside of the tank body, with its top end communicating with the top of the air flow chamber and its bottom end communicating with the water tank and being below the water surface inside the water tank;

[0021] The air flow flowing upward along the cooling cylinder enters the inside of the air flow guiding pipe communicating with the cooling cylinder, and then flows inside the air flow guiding pipe. At the same time, the outside air flow flows through the air flow guiding pipe, so that the temperature of the air flow inside the air flow guiding pipe gradually decreases, the water in the air flow is separated out, and the separated cooling water returns to the inside of the water tank again. This is beneficial to reducing the water flow loss during the cooling process and avoiding the situation that the concentration of salt substances in the cooling water gradually increases after the water flow loss and scale forms on the surfaces of equipment such as heat exchangers and pipelines.

[0022] Preferably, the air flow guiding assembly further includes:

[0023] A first guiding hopper, fixedly connected to the top port of the air flow guiding pipe;

[0024] A plurality of air cooling pipes, fixedly connected in an array to the large-mouth end of the first guiding hopper, and the bottoms of all the air cooling pipes are fixedly connected to the top of the air flow chamber. The air cooling pipes are heat-conducting metal pipes;

[0025] Before entering the air flow guiding pipe, the air flow enters the inside of the air cooling pipes. The setting of multiple air cooling pipes enables the air flow to flow through the inside of each air cooling pipe after being dispersed. Then the air flow flows along the first guiding hopper and converges into the inside of the air flow guiding pipe. The setting of multiple air cooling pipes disperses the air flow, thereby increasing the contact area between the air flow and the heat-conducting metal of the air cooling pipes, increasing the heat exchange rate between the air flow and the outside low-temperature air flow, accelerating the cooling of the air flow, enabling the air flow to separate out cooling water after cooling, increasing the amount of separated cooling water, and thus reducing the loss of water volume.

[0026] Preferably, the air flow guiding assembly further includes:

[0027] A straight rod, fixed at the center inside the water tank;

[0028] A rotating sleeve, sleeved on the outer circle of the straight rod;

[0029] An impeller, fixed to the outer circle of the rotating sleeve;

[0030] Stirring rods, fixedly arranged in a circumferential array on the outer wall of the rotating sleeve;

[0031] The drain port at the bottom of the air flow guiding pipe is located below the impeller;

[0032] After the air flow is discharged from the air flow guiding pipe, the discharged air flow impacts the impeller, thereby driving the impeller to rotate. The impeller drives the rotating sleeve to rotate, and the rotating sleeve drives the stirring rod to rotate. After the stirring rod rotates, the flow of the cooling water inside the water tank is accelerated, so as to accelerate the dissipation of the heat in the water flow inside the water tank by accelerating the flow of the cooling water, which is beneficial to slowing down the temperature rise of the cooling water.

[0033] Preferably, it further includes:

[0034] A heat dissipation wheel, fixed inside the cooling cylinder through a support frame, and is arranged in a double-cone shape;

[0035] A guiding strip, fixed on the outer surface of the upper end of the heat dissipation wheel;

[0036] A first opening, penetrating through the side wall of the guiding strip in a circumferential array;

[0037] A scale inhibitor rod, inserted and installed at the bottom of the heat dissipation wheel;

[0038] A spiral blade, fixed on the outer surface of the lower end of the heat dissipation wheel to guide part of the cooling water towards the scale inhibitor rod;

[0039] The cooling water sprayed by the nozzle falls on the heat dissipation wheel and flows around under the guiding action of the inclined surface at the top of the heat dissipation wheel. The guiding strip intercepts the flowing cooling water, so that the cooling water flows down along the first opening, thereby slowing down the flow rate of the cooling water, increasing the heat exchange between the cooling water and the heat dissipation wheel, and further cooling the cooling water. When a large amount of cooling water dissipates around the heat dissipation wheel, only a small amount of cooling water flows to the bottom surface of the heat dissipation wheel, so that the water flow flows towards the scale inhibitor rod under the guiding action of the spiral blade when flowing along the bottom surface of the heat dissipation wheel. The cooling water flowing to the scale inhibitor rod drives part of the scale inhibitor to dissolve into the cooling water, and then falls into the inside of the water tank along with the cooling water, so that the scale inhibitor in the scale inhibitor rod gradually dissolves into the cooling water, which is beneficial to slowing down the formation of scale;

[0040] When accelerating the cooling effect of the tank body, the water pump will be accelerated to drive the cooling water, so that the flow rate of the water flow increases. When the flow rate of the water flow increases, the amount of water sprayed by the nozzle and flowing to the heat dissipation wheel increases synchronously, so that the amount of water flowing through the scale inhibitor rod increases, thereby increasing the dissolution of the scale inhibitor in the scale inhibitor rod. When the water flow increases and the evaporation and overflow of water are accelerated, the dissolution amount of the scale inhibitor can be increased to avoid increasing the formation of scale when the water flow accelerates.

[0041] Preferably, it further includes:

[0042] An air inlet pipe, one end of which is fixedly connected to the inner cavity of the heat dissipation wheel, and the other end penetrates through the cooling cylinder and the tank body in a sealed manner;

[0043] The installation pipe is fixed to the end of the air inlet pipe after it penetrates through the tank body;

[0044] The second driving fan is fixedly installed inside the installation pipe;

[0045] The exhaust air pipe is fixedly connected to the inner cavity of the heat dissipation wheel at one end and penetrates through the cooling cylinder and the tank body in a sealed manner at the other end;

[0046] The fixed hopper is fixed inside the inner cavity. There is a gap between the edge of the fixed hopper and the inner wall of the inner cavity. The fixed hopper is located between the air inlet pipe and the exhaust air pipe;

[0047] After the second driving fan is started, it drives the air flow to enter the inside of the air inlet pipe along the installation pipe. Then the air flow enters the upper part inside the heat dissipation wheel, flows along the gap between the edge of the fixed hopper and the inner wall of the inner cavity to the lower part inside the heat dissipation wheel, and then is discharged along the exhaust air pipe. Thus, the outside air flow flows in the inner cavity of the heat dissipation wheel, and the heat of the heat dissipation wheel is dissipated by the flow of the outside air flow. Then, the cooling water is cooled again by the heat dissipation wheel to increase the cooling effect on the cooling water and restore the cooling effect of the cooling water.

[0048] Preferably, it further includes:

[0049] The telescopic pipe is fixedly connected to the bottom of the fixed hopper;

[0050] The fixed plate is fixed to the bottom of the telescopic pipe;

[0051] The top of the scale inhibitor rod penetrates and extends into the inner cavity, and the bottom of the fixed plate presses the scale inhibitor rod;

[0052] When the air flow enters the inside of the heat dissipation wheel along the air inlet pipe, due to the existence of the gap between the edge of the fixed hopper and the inner wall of the inner cavity, it causes a certain obstruction to the flow of the air flow, so that the air pressure rises at the position above the fixed hopper. The increased air pressure pushes the fixed plate, causing the telescopic pipe to elongate, and the telescopic pipe moves downward under the action of the air pressure to push the scale inhibitor rod, so that the scale inhibitor rod can gradually move downward. This helps to avoid the situation that after the bottom of the scale inhibitor rod is dissolved due to the flow of the cooling water passing through the bottom, the scale inhibitor rod above is not replenished in time, which affects the inhibition of scale.

[0053] Preferably, it further includes:

[0054] The lifting sleeve is inserted through the bottom of the heat dissipation wheel and sleeved outside the scale inhibitor rod;

[0055] The bottom support is fixed to the bottom of the lifting sleeve, and the bottom support supports the bottom of the scale inhibitor rod;

[0056] A plurality of second openings are arranged on the outer wall of the lifting sleeve in a circumferential array;

[0057] A projection, fixed to the top of the base, for guiding the flow of cooling water;

[0058] A mounting plate, fixed inside the inner cavity;

[0059] Two first cylinders, symmetrically fixed to the top of the mounting plate, and the first cylinders drive the lifting sleeve to move vertically through the telescopic rods;

[0060] After the first cylinder is activated, it drives the lifting sleeve to move vertically through the telescopic rod, thereby driving the base at the bottom of the lifting sleeve to move synchronously. The bottom of the scale inhibitor rod is supported by the base, so that the bottom of the scale inhibitor rod is no longer pushed downward when it is squeezed by the projection, thereby restricting the downward movement of the scale inhibitor rod. This is beneficial to avoid the situation where the excessive downward movement of the scale inhibitor rod causes too much dissolution of the scale inhibitor. By adjusting the height of the lifting sleeve through the first cylinder, the amount of downward movement of the scale inhibitor rod is controlled, so as to control the dissolution amount of the scale inhibitor in the scale inhibitor rod;

[0061] The projection can guide the water flow, which is beneficial to avoid the situation where the water flow accumulates on the base and causes excessive dissolution of the scale inhibitor rod.

[0062] Preferably, it further includes:

[0063] A mounting frame, fixed inside the cooling cylinder;

[0064] A second cylinder, fixed to the top of the mounting frame;

[0065] A second guiding hopper, fixed to the top of the telescopic rod of the second cylinder, and the distance between the inner wall of the second guiding hopper and the outer wall of the heat dissipation wheel is adjusted during vertical movement;

[0066] After the second cylinder is activated, it pushes the second guiding hopper to move vertically through the telescopic rod. When the second guiding hopper moves up to the topmost position, it can fit the bottom of the heat dissipation wheel, so that the water flow is difficult to flow through the inside of the second guiding hopper, thereby blocking the flow of water to the scale inhibitor rod. When the second cylinder drives the second guiding hopper to move downward, the flow of water into the inside of the second guiding hopper can be increased, thereby increasing the flow of water to the scale inhibitor rod, so as to adjust the dissolution amount of the water flow driving the scale inhibitor rod, and avoid the situation where the scale inhibitor is dissolved too little or dissolved excessively.

[0067] Compared with the prior art, the present invention has the following beneficial effects:

[0068] 1. Through the setting of the air flow guiding component in the present invention, the air flow cools down when passing through the air flow guiding component, so that the moisture contained in the air flow is precipitated under the action of condensation. The precipitated water flow returns to the cooling cylinder or enters the water tank along the air flow guiding component, which is beneficial to reduce the dissipation of moisture.

[0069] 2. Through the settings of the heat dissipation wheel and the scale inhibitor rod in the present invention, when the water flow flows along the bottom surface of the heat dissipation wheel, it flows towards the scale inhibitor rod under the guiding action of the spiral blades. The cooling water flowing to the scale inhibitor rod drives part of the scale inhibitor to dissolve into the cooling water, and then falls into the interior of the water tank along with the cooling water. As a result, the scale inhibitor in the scale inhibitor rod gradually dissolves into the cooling water, which is beneficial to slowing down the formation of scale.

[0070] 3. Through the setting of the lifting sleeve in the present invention, the amount of downward movement of the scale inhibitor rod is controlled to control the dissolution amount of the scale inhibitor in the scale inhibitor rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0080] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variants can be thought of by those skilled in the art.

[0081] As Figures 1 to 8 shown, a fermentation tank for recycling cooling water in a circulating manner includes a tank body 1, the tank body 1 includes a feeding pipe 101 and a discharging pipe 102, and further includes:

[0082] A cooling cylinder 2, which is inserted through the middle of the tank body 1;

[0083] A water tank 202, which is fixed to the bottom of the cooling cylinder 2;

[0084] A cooling pipe 201, which is arranged in a spiral shape inside the tank body 1, one end of the cooling pipe 201 extends through the inside of the cooling cylinder 2, and the other end is inside the water tank 202 and is fixed with a water pump 203;

[0085] A circulating cooling component, which is installed inside the cooling cylinder 2 and is used to cool the cooling water discharged from the cooling pipe 201 through air flow and then make it fall into the water tank 202 to form a cycle;

[0086] An air flow guiding component, which is installed outside the tank body 1 and is used to guide and condense the air flow used for cooling by the circulating cooling component, so as to recover the moisture carried in the air flow and convey the air flow into the water tank 202 to drive the cooling water to fluctuate;

[0087] For the cooling of existing fermenters, generally, cold water sources are directly used to cool the fermenters, and the cooling water is directly discharged, resulting in serious waste of water resources. Or a simple water cycle is carried out using a water storage tank. When the cooling water is circulated, on the one hand, the circulated cooling water will cause the temperature to increase when cooling the fermenter, resulting in an impact on the cooling effect. On the other hand, water continuously volatilizes during the cooling process of the circulated cooling water, resulting in a gradual increase in the concentration of salt substances in the remaining cooling water. When the concentration of these salt substances exceeds their solubility, scale will form on the surfaces of equipment such as heat exchangers and pipelines. The formation of scale will not only greatly reduce the heat transfer efficiency, increase the energy consumption of the equipment, but also may cause local overheating of the equipment, affecting the normal operation of the equipment;

[0088] This embodiment of the present invention can solve the above problems. The specific implementation manner is as follows. When the fermenter needs to be cooled, the water pump 203 is started. After the water pump 203 is started, it drives the cooling water inside the water tank 202 to flow along the cooling pipe 201. The cooling pipe 201 spirally passes through the inside of the tank body 1, so as to cool the inside of the tank body 1 when the cooling water passes through. Subsequently, the cooling water is transported along the cooling pipe 201 to the circulating cooling component. The circulating cooling component is inside the cooling cylinder 2 and cools the cooling water flowing through the cooling pipe 201. Thus, after the temperature of the cooling water drops, it returns to the inside of the water tank 202 again, which is beneficial to avoiding the situation that the cooling water gradually heats up during the cooling process, thereby affecting the cooling effect of the cooling water on the inside of the tank body 1;

[0089] The circulating cooling component cools the heated cooling water through air flow. When the air flow passes through the cooling water, a large amount of water is carried away. At this time, the air flow is guided into the air flow guiding component, so that the air flow cools down when passing through the air flow guiding component, and the water contained in the air flow precipitates under the condensation action. The precipitated water flows back to the cooling cylinder 2 or enters the water tank 202 along the air flow guiding component. Thus, it is beneficial to reduce the escape of water, and the flowing air flow enters the water tank 202 after passing through the air flow guiding component and is discharged below the water surface of the water tank 202. The discharged air flow impacts the cooling water inside the water tank 202, causing the water flow inside the water tank 202 to flow, which is beneficial to driving the further cooling of the cooling water inside the water tank 202, thereby avoiding the situation that the cooling water heats up during the cooling process and affects the cooling effect.

[0090] As an optional embodiment, the circulating cooling component includes:

[0091] A fixed pipe 204, fixed inside the cooling cylinder 2, and one end of the cooling pipe 201 extending into the cooling cylinder 2 is fixedly communicated with the fixed pipe 204;

[0092] A plurality of nozzles 205, fixedly installed at the bottom of the fixed pipe 204 in a linear array, for spraying the cooling water entering the fixed pipe 204;

[0093] The air flow bin 302 is fixedly connected to the top of the cooling cylinder 2;

[0094] The first driving fan 3 is fixedly installed inside the air flow bin 302;

[0095] The cooling water flows along the cooling pipe 201 into the inside of the fixed pipe 204, and then sprays out from the nozzle 205 at the bottom of the fixed pipe 204. At the same time, the first driving fan 3 drives the air flow to flow upward along the cooling cylinder 2. The air flow flowing to the cooling cylinder 2 enters from the outside along the surface of the water tank 202 into the bottom of the cooling cylinder 2. When the air flow flows through the inside of the cooling cylinder 2, it passes through the cooling water sprayed out from the nozzle 205. At this time, the contact area between the sprayed cooling water and the air flow increases, so that the cooling effect of the air flow on the cooling water increases, which is beneficial to cooling the cooling water, so that the cooled cooling water falls into the inside of the water tank 202, which is beneficial to avoiding the situation that the cooling effect is affected after the cooling water is heated.

[0096] As an alternative embodiment, the air flow guiding assembly includes:

[0097] The air flow guiding pipe 301 is fixed to the outside of the tank body 1, the top end is connected to the top of the air flow bin 302, the bottom end is connected to the water tank 202, and is located below the water surface inside the water tank 202;

[0098] The air flow flowing upward along the cooling cylinder 2 enters the inside of the air flow guiding pipe 301 connected to the cooling cylinder 2, and then flows inside the air flow guiding pipe 301. At the same time, the outside air flow flows through the air flow guiding pipe 301, so that the temperature of the air flow inside the air flow guiding pipe 301 gradually decreases, so that the water in the air flow precipitates, and the precipitated cooling water returns to the inside of the water tank 202 again, which is beneficial to reducing the water flow loss during the cooling process, and is beneficial to avoiding the situation that the concentration of salt substances in the cooling water gradually increases after the water flow loss and scale is formed on the surfaces of equipment such as heat exchangers and pipelines.

[0099] As an alternative embodiment, the air flow guiding assembly further includes:

[0100] The first guiding hopper 4 is fixedly connected to the top port of the air flow guiding pipe 301;

[0101] A plurality of air-cooled pipes 401 are fixedly connected to the large-mouth end of the first guiding hopper 4 in an array, and the bottoms of all the air-cooled pipes 401 are fixedly connected to the top of the air flow bin 302. The air-cooled pipes 401 are heat-conducting metal pipes;

[0102] Before the air flow enters the air flow guiding pipe 301, it enters the interior of the air cooling pipe 401. The arrangement of multiple air cooling pipes 401 enables the air flow to flow through the interior of each air cooling pipe 401 after being dispersed. Subsequently, the air flow converges into the interior of the air flow guiding pipe 301 along the first guiding hopper 4. The arrangement of multiple air cooling pipes 401 disperses the air flow, thereby increasing the contact area between the air flow and the heat-conducting metal of the air cooling pipe 401, thereby increasing the heat exchange rate between the air flow and the external low-temperature air flow, thereby accelerating the cooling of the air flow, so that cooling water is precipitated after the air flow is cooled, increasing the precipitation amount of the cooling water, and thus reducing the water loss.

[0103] As an alternative embodiment, the air flow guiding assembly further includes:

[0104] A straight rod 504, fixed at the central position inside the water tank 202;

[0105] A rotating sleeve 501, rotatably sleeved on the outer circle of the straight rod 504;

[0106] An impeller 502, fixed on the outer circle of the rotating sleeve 501;

[0107] Stirring rods 5, fixedly arranged on the outer wall of the rotating sleeve 501 in a circumferential array;

[0108] The drain port 503 at the bottom of the air flow guiding pipe 301 is located below the impeller 502;

[0109] After the air flow is discharged from the air flow guiding pipe 301, the discharged air flow impacts the impeller 502, thereby driving the impeller 502 to rotate. The impeller 502 drives the rotating sleeve 501 to rotate, and the rotating sleeve 501 drives the stirring rods 5 to rotate. After the stirring rods 5 rotate, the flow of the cooling water inside the water tank 202 is accelerated, so as to accelerate the dissipation of heat in the water flow inside the water tank 202 by accelerating the flow of the cooling water, which is beneficial to slowing down the temperature rise of the cooling water.

[0110] As an alternative embodiment, it further includes:

[0111] A heat dissipation wheel 6, fixed inside the cooling cylinder 2 through a support frame 605, and is arranged in a double-cone shape;

[0112] A guiding strip 601, fixed on the upper outer surface of the heat dissipation wheel 6;

[0113] First openings 602, penetrating through the side wall of the guiding strip 601 in a circumferential array;

[0114] A scale inhibitor rod 603, inserted and installed at the bottom of the heat dissipation wheel 6;

[0115] Helical blades 604, fixed on the lower outer surface of the heat dissipation wheel 6 to guide part of the cooling water towards the scale inhibitor rod 603;

[0116] The cooling water sprayed by the spray head 205 falls on the heat dissipation wheel 6 and flows around under the guiding action of the top inclined surface of the heat dissipation wheel 6. The guiding strip 601 intercepts the flowing cooling water, causing the cooling water to flow along the first opening 602, so as to slow down the flow rate of the cooling water, thereby increasing the heat exchange between the cooling water and the heat dissipation wheel 6 to further cool the cooling water. When a large amount of cooling water dissipates around along the heat dissipation wheel 6, only a small amount of cooling water flows to the bottom surface of the heat dissipation wheel 6, causing the water flow to flow towards the scale inhibitor rod 603 under the guiding action of the spiral blade 604 when flowing along the bottom surface of the heat dissipation wheel 6. The cooling water flowing to the scale inhibitor rod 603 drives part of the scale inhibitor to dissolve into the cooling water, and then falls into the interior of the water tank 202 along with the cooling water, so that the scale inhibitor in the scale inhibitor rod 603 gradually dissolves into the cooling water, which is conducive to slowing down the formation of scale;

[0117] When accelerating the cooling effect of the tank body 1, the water pump 203 will be accelerated to drive the cooling water, so that the flow rate of the water flow increases. When the flow rate of the water flow increases, the amount of water sprayed by the spray head 205 and flowing to the heat dissipation wheel 6 increases synchronously, so that the amount of water flowing through the scale inhibitor rod 603 increases, thereby increasing the dissolution of the scale inhibitor in the scale inhibitor rod 603. When the water flow increases and the evaporation and overflow of water are accelerated, the dissolution amount of the scale inhibitor can be increased to avoid increasing the formation of scale when the water flow accelerates.

[0118] As an alternative embodiment, it further includes:

[0119] An air inlet pipe 7, one end of which is fixedly communicated with the inner cavity of the heat dissipation wheel 6, and the other end of which hermetically penetrates through the cooling cylinder 2 and the tank body 1;

[0120] An installation pipe 701, fixed to the end of the air inlet pipe 7 after it penetrates through the tank body 1;

[0121] A second driving fan 702, fixedly installed inside the installation pipe 701;

[0122] An air outlet pipe 703, one end of which is fixedly communicated with the inner cavity of the heat dissipation wheel 6, and the other end of which hermetically penetrates through the cooling cylinder 2 and the tank body 1;

[0123] A fixed hopper 704, fixed inside the inner cavity. There is a gap between the edge of the fixed hopper 704 and the inner wall of the inner cavity. The fixed hopper 704 is located between the air inlet pipe 7 and the air outlet pipe 703;

[0124] After the second driving fan 702 starts, it drives the air flow to enter the interior of the air inlet pipe 7 along the installation pipe 701. Subsequently, the air flow enters the upper part inside the heat dissipation wheel 6, flows along the gap between the edge of the fixed hopper 704 and the inner wall of the inner cavity to the lower part inside the heat dissipation wheel 6, and then is discharged along the exhaust pipe 703. As a result, the external air flow flows in the inner cavity of the heat dissipation wheel 6, and the flowing of the external air flow dissipates the heat of the heat dissipation wheel 6. Thus, the cooling water is further cooled by the heat dissipation wheel 6 to enhance the cooling effect on the cooling water and restore the cooling effect of the cooling water.

[0125] As an alternative embodiment, it further includes:

[0126] The telescopic pipe 801 is fixedly connected to the bottom of the fixed hopper 704;

[0127] The fixing plate 8 is fixed to the bottom of the telescopic pipe 801;

[0128] The top of the scale inhibitor rod 603 extends through to the inside of the inner cavity, and the bottom of the fixing plate 8 presses against the scale inhibitor rod 603;

[0129] When the air flow enters the inside of the heat dissipation wheel 6 along the air inlet pipe 7, due to the existence of the gap between the edge of the fixed hopper 704 and the inner wall of the inner cavity, it causes a certain obstruction to the flow of the air flow, resulting in an increase in air pressure at the position above the fixed hopper 704. The increased air pressure pushes the fixing plate 8, causing the telescopic pipe 801 to extend, and the telescopic pipe 801 moves downward under the action of the air pressure to push the scale inhibitor rod 603. As a result, the scale inhibitor rod 603 can gradually move downward, which helps to avoid the situation where, after the bottom of the scale inhibitor rod 603 is dissolved due to the flow of the cooling water passing through the bottom, the scale inhibitor rod 603 above is not replenished in time, affecting the inhibition of water scale.

[0130] As an alternative embodiment, it further includes:

[0131] The lifting sleeve 9 is inserted through the bottom of the heat dissipation wheel 6 and sleeved outside the scale inhibitor rod 603;

[0132] The bottom support 901 is fixed to the bottom of the lifting sleeve 9, and the bottom support 901 supports the bottom of the scale inhibitor rod 603;

[0133] A plurality of second openings 902 are formed in a circumferential array on the outer wall of the lifting sleeve 9;

[0134] The protrusion 903 is fixed to the top of the bottom support 901 to guide the flow of the cooling water;

[0135] The mounting plate 904 is fixed to the inside of the inner cavity;

[0136] Two first cylinders 905 are symmetrically fixed to the top of the mounting plate 904, and the first cylinders 905 drive the lifting sleeve 9 to move vertically through the telescopic rods;

[0137] After the first cylinder 905 is started, the lifting sleeve 9 is driven to move vertically through the telescopic rod, thereby driving the bottom support 901 at the bottom of the lifting sleeve 9 to move synchronously, and the bottom support 901 supports the bottom of the scale inhibitor rod 603, so that the bottom of the scale inhibitor rod 603 is no longer pushed downward when the protrusion 903 is squeezed, thereby limiting the downward movement of the scale inhibitor rod 603, which is conducive to avoiding the situation where the scale inhibitor rod 603 moves downward excessively and causes excessive dissolution of the scale inhibitor. The height of the lifting sleeve 9 is adjusted by the first cylinder 905, thereby controlling the downward movement of the scale inhibitor rod 603, so as to control the dissolution amount of the scale inhibitor in the scale inhibitor rod 603;

[0138] The protrusion 903 can guide the water flow, thereby preventing the water from accumulating on the base 901 and causing excessive dissolution of the antiscalant rod 603 .

[0139] As an optional embodiment, it also includes:

[0140] The mounting frame 1001 is fixed inside the cooling cylinder 2;

[0141] The second cylinder 1002 is fixed to the top of the mounting frame 1001;

[0142] The second guide bucket 10 is fixed to the top of the telescopic rod of the second cylinder 1002, and the inner wall of the second guide bucket 10 is adjusted to a distance from the outer wall of the heat dissipation wheel 6 when moving vertically;

[0143] After the second cylinder 1002 is started, the second guide bucket 10 is pushed to move vertically through the telescopic rod. After the second guide bucket 10 moves upward to the top, it can fit the bottom of the heat dissipation wheel 6, making it difficult for water to flow through the inside of the second guide bucket 10, thereby blocking the flow of water to the scale inhibitor rod 603. When the second cylinder 1002 drives the second guide bucket 10 to move downward, the flow of water to the inside of the second guide bucket 10 can be increased, thereby increasing the flow of water to the scale inhibitor rod 603, thereby adjusting the dissolution amount of the scale inhibitor rod 603 driven by the water flow, so as to avoid the occurrence of insufficient or excessive dissolution of the scale inhibitor.

[0144] Working principle of the present invention: When it is necessary to cool the fermentation tank, the water pump 203 is started. After the water pump 203 is started, it drives the cooling water inside the water tank 202 to flow along the cooling pipe 201. The cooling pipe 201 spirally passes through the inside of the tank body 1, so as to cool the inside of the tank body 1 when the cooling water passes through. Subsequently, the cooling water is transported along the cooling pipe 201 to the circulating cooling component. The circulating cooling component is inside the cooling cylinder 2 and cools the cooling water flowing through the cooling pipe 201. Thus, after the temperature of the cooling water drops, it returns to the inside of the water tank 202 again, which helps to avoid the situation that the cooling water gradually warms up during the cooling process, thereby affecting the cooling effect of the cooling water on the inside of the tank body 1;

[0145] The circulating cooling component cools the heated cooling water through air flow. A large amount of water is carried away when the air flow passes through the cooling water. At this time, the air flow is guided into the air flow guiding component, so that the air flow cools down when passing through the air flow guiding component, and the water contained in the air flow precipitates under the condensation effect. The precipitated water flows back to the cooling cylinder 2 or enters the water tank 202 along the air flow guiding component. This helps to reduce the dissipation of water. Moreover, the flowing air flow enters the water tank 202 after passing through the air flow guiding component and is discharged from below the water surface of the water tank 202. The discharged air flow impacts the cooling water inside the water tank 202, causing the water flow inside the water tank 202 to flow, which helps to drive the further cooling of the cooling water inside the water tank 202, thus avoiding the situation that the cooling water warms up during the cooling process and affects the cooling effect.
