[0002] The fermentation heat recovery device for cooling towers can effectively recover the heat energy generated during fermentation. When processing fermentation materials, the device can capture the heat generated during fermentation and transfer the heat energy to other media, such as water, through heat exchange and other means, so as to realize the reuse of heat energy. The recovered heat energy can be used to heat production water, provide heat for other equipment, reduce energy waste, reduce production costs, reduce the impact of direct heat energy emissions on the environment, and improve energy utilization efficiency.

[0003] In the prior art, wheat flour and barley flour are fermented using microorganisms in a fermentation machine. It is necessary to maintain the temperature of the fermentation tank and to discharge the waste gas inside the tank. The waste gas generated inside the fermentation tank is generally 30-40°C. In the prior art, it is generally directly discharged to the outside, which wastes this heat and is prone to causing environmental pollution. Therefore, this utility model proposes a fermentation heat energy recovery device for cooling towers to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a heat recovery device for fermentation materials used in cooling towers, which solves the problem that existing wheat flour and barley flour fermentation machines directly discharge heat into the outside environment, wasting this heat and easily causing environmental pollution.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a heat energy recovery device for fermentation materials in a cooling tower, comprising a fermenter, a cooling tower and a preheating chamber, wherein a cooling tower is provided on one side of the fermenter, a preheating chamber is provided between the fermenter and the cooling tower, a heat energy recovery mechanism is provided between the fermenter, the cooling tower and the preheating chamber, a feeding pipe is connected to the bottom of the fermenter, a material tray is installed on the top of the fermenter through a detachable mechanism, and an exhaust pipe is connected to the back side of the fermenter.

[0006] A further improvement is that the detachable mechanism includes a plug, a slot, a groove, a spring, and a top block. Plugs are symmetrically fixedly connected to both sides of the bottom of the material tray. A set of slots is symmetrically provided on both sides of the preheating chamber. Grooves are symmetrically provided on both sides of the plug. Springs are symmetrically fixedly connected to both sides of the slots. One end of the spring is fixedly connected to the top block.

[0007] A further improvement is that one end of both the insert block and the top block is a conical head, the top block and the groove are at the same height, and the insert block and the slot are parallel vertically.

[0008] A further improvement is that the fermenter has an inner cylinder inside, and multiple spiral tubes are provided on the outside of the inner cylinder. The bottom and top ends of the multiple spiral tubes are all connected to a material collection pipe.

[0009] Further improvements are made in that: the heat recovery mechanism includes a coil, a conveying pipe, a return pipe and a water pump. The preheating chamber is equipped with a coil, and both ends of the coil are connected to conveying pipes. One end of each conveying pipe is connected to the cooling tower and the material collection pipe at the top of the spiral tube, respectively. The material collection pipe at the bottom of the spiral tube is connected to the return pipe, and one end of the return pipe is connected to the bottom of the cooling tower. A water pump is installed on the conveying pipe and the return pipe.

[0010] A further improvement is that: solenoid valves are installed on the feed pipe, the conveying pipe, and the return pipe; a sealing cap is threaded to the top of the fermentation tank; and a sealing ring is provided on the top of the sealing cap.

[0011] A further improvement is that the material tray is composed of an outer ring and a copper sheet layer, with the mesh layer fixed inside the outer ring, and the outer ring is made of stainless steel.

[0012] The beneficial effects of this utility model are as follows: When the bottom end of the insert block is inserted into the inside of the slot, the bottom end of the insert block first presses the two top blocks to move towards the inside of the slot, while the spring is in a compressed state. When the top blocks and the groove are parallel to each other, the elastic force generated by the spring drives the top blocks to return to their original position and insert the top blocks into the inside of the groove. The insert block and the slot are locked together. The material tray is fixed to the top of the preheating chamber through the return pipe. The top of the coil contacts the bottom of the material tray, transferring heat energy to the inside of the material tray. This makes it convenient to use the heat energy generated by the exhaust gas to preheat the fermented wheat flour, which can reduce the energy consumption of the subsequent drying heating process.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a heat recovery device for fermentation materials used in cooling towers, including a fermentation tank 1, a cooling tower 2, and a preheating chamber 3. The cooling tower 2 is located on one side of the fermentation tank 1, and the preheating chamber 3 is located between the fermentation tank 1 and the cooling tower 2. A heat recovery mechanism is provided between the fermentation tank 1, the cooling tower 2, and the preheating chamber 3. The bottom of the fermentation tank 1 is connected to a feeding pipe 4, and the top of the fermentation tank 1 is equipped with a detachable feeding tray 5. An exhaust pipe is connected to the back side of the fermentation tank 1. Wheat and barley flour are placed inside the fermentation tank 1 for fermentation. During the fermentation process, waste gas with a temperature of 30-40°C is generated. The heat is introduced into the preheating chamber 3 through the heat recovery mechanism. The fermented wheat and barley flour is placed on top of the feeding tray 5. The heat generated by the waste gas is used to preheat the wheat and barley flour, which can reduce the energy consumption of the subsequent drying heating process.

[0020] The detachable mechanism includes an insert 7, a slot 8, a groove 9, a spring 10, and a top block 11. Inserts 7 are symmetrically fixed to both sides of the bottom of the feeding tray 5. A set of slots 8 are symmetrically arranged on both sides of the preheating chamber 3. Grooves 9 are symmetrically arranged on both sides of the insert 7. Springs 10 are symmetrically fixed to both sides of the slots 8. One end of the spring 10 is fixedly connected to a top block 11. When the bottom end of the insert 7 is inserted into the slot 8, the bottom end of the insert 7 first presses the two top blocks 11 towards the inside of the slot 8. At the same time, the spring 10 is in a compressed state. When the top block 11 and the groove 9 are parallel to each other, the elastic force generated by the spring 10 drives the top block 11 to reset and insert it into the groove 9. The insert 7 and the slot 8 are engaged as one unit. The feeding tray 5 is fixed to the top of the preheating chamber 3 through the return pipe 6. The top of the coil 12 contacts the bottom of the feeding tray 5, transferring heat energy to the inside of the feeding tray 5, facilitating the preheating of the fermented wheat flour using the heat energy generated by the exhaust gas.

[0021] Both the insert block 7 and the top block 11 have a conical head at one end. The top block 11 and the groove 9 are at the same height. The insert block 7 and the slot 8 are parallel vertically. After preheating, the material tray 5 is pulled upwards to pull the insert block 7 out of the slot 8 and remove the material tray 5 from the top of the preheating chamber 3. The material tray 5 can prevent the fermented wheat flour from directly contacting the coil 12, and prevent the juice produced by the fermentation of wheat flour from dripping onto the coil 12 and being difficult to clean. After the material tray 5 is removed, it can be rinsed with clean water.

[0022] The fermenter 1 has an inner cylinder 13 inside, and multiple spiral tubes 14 are provided on the outside of the inner cylinder 13. The bottom and top of the multiple spiral tubes 14 are connected to a material collection pipe.

[0023] The heat recovery mechanism includes a coil 12, a conveying pipe 16, a return pipe 6, and a water pump 17. The preheating chamber 3 is equipped with a coil 12, with conveying pipes 16 connected to both ends of the coil 12. One end of each conveying pipe 16 is connected to the cooling tower 2 and the top collection pipe of the spiral tube 14, respectively. The bottom collection pipe of the spiral tube 14 is connected to the return pipe 6, with one end of the return pipe 6 connected to the bottom of the cooling tower 2. A water pump 17 is installed on the conveying pipes 16 and the return pipe 6. The wheat flour ferments inside the inner cylinder 13. The cooling tower 2, through the cooperation of the water pump 17, conveys cold water from the bottom of the cooling tower 2 to the collection pipe at the bottom of the spiral tube 14. The cold water flows upwards spirally through multiple spiral tubes 14, allowing sufficient time to absorb the wheat flour. The heat generated by the waste gas during fermentation is transported through the collection pipe at the top of the spiral tube 14, the conveying pipe 16 on the left side of the preheating chamber 3, and the water pump 17 to the coil 12 inside the preheating chamber 3. The coil structure of the coil 12 extends the time of the hot water in the preheating chamber 3, so as to fully preheat the fermented wheat flour. Then, it is transported to the top of the cooling tower 2 through the conveying pipe 16 on the right side of the preheating chamber 3 and the water pump 17. The hot and humid water is sprayed into the interior of the cooling tower 2. The water evaporates in the cooling tower 2, taking away the heat and thus lowering the water temperature. Then, the water pump 17 is used to transport it again to the collection pipe at the bottom of the spiral tube 14, thus forming a closed loop of "heating-cooling-reheating", and the device continues to operate.

[0024] Solenoid valves are installed on the feeding pipe 4, the conveying pipe 16, and the return pipe 6. A sealing cap 15 is threadedly connected to the top of the fermentation tank 1. A sealing ring is provided on the top of the sealing cap 15. By rotating the sealing cap 15 in both directions, it is screwed into or out of the top of the fermentation tank 1 to open the channel at the top of the fermentation tank 1 and put wheat flour and various auxiliary materials into the inner cylinder 13. Then, the sealing cap 15 is installed on the top of the fermentation tank 1, and the sealing ring on the top of the sealing cap 15 can fill the gap between the sealing cap 15 and the top of the fermentation tank 1 to ensure the sealing between the sealing cap 15 and the top of the fermentation tank 1.

[0025] The material tray 5 is composed of an outer ring and a copper sheet layer, with the mesh layer fixed inside the outer ring. The outer ring is made of stainless steel.

[0026] The cooling tower uses a fermentation heat recovery device. The bottom end of the insert 7 is inserted into the slot 8. The bottom end of the insert 7 first presses the two top blocks 11 to move inward into the slot 8. At the same time, the spring 10 is in a compressed state. When the top blocks 11 and the groove 9 are parallel to each other, the elastic force generated by the spring 10 drives the top blocks 11 to reset and insert them into the groove 9. The insert 7 and the slot 8 are locked together. The material tray 5 is fixed to the top of the preheating chamber 3 through the return pipe 6. The top of the coil 12 contacts the bottom of the material tray 5, transferring heat energy to the inside of the material tray 5. This allows the heat energy generated by the exhaust gas to be used to preheat the fermented wheat flour, which can reduce the energy consumption of the subsequent drying heating process.
