Description

Technical Field

[0001] The present invention belongs to the field of regulating the internal temperature, humidity and air volume of a fermentation chamber, and relates to a device for regulating the internal temperature, humidity and air volume of a fermentation chamber. Background Art

[0002] A fermentation chamber is a place for microbial fermentation culture and is a laboratory integrating teaching and scientific research; the fermentation chamber is mainly used for undergraduate professional experiments, training experiments, innovation experiments, graduate professional experiments, scientific research of experimental teachers and social services, etc.; in addition, the fermentation process in fields such as food, alcohol, medicine and biomass also uses a fermentation chamber, and the most important thing during the use of the fermentation chamber is to control the required temperature and humidity to keep the best fermentation environment inside the fermentation chamber. The existing temperature and humidity inside the fermentation chamber are adjusted by an air conditioner. An air conditioner, that is, an air conditioner, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, cleanliness, and flow rate of the air environment inside a building or structure; most air conditioners utilize the action of a refrigerant to evaporate or condense, thereby causing the evaporation or condensation of the surrounding air to achieve the purpose of changing the temperature and humidity.

[0003] However, for existing wall-mounted air conditioners, floor-standing air conditioners, and central air conditioners, the air outlets of these air conditioners are fixed and the positions are single, resulting in a rapid change in temperature at the position directly facing the air outlet, while the other positions need to be adjusted slowly through air circulation. If the air outlet for delivering cold air is at a lower position, it is difficult to deliver this cold air to a higher position; if the air outlet for delivering hot air is at a higher position, it is difficult to deliver this hot air to a lower position. This causes a large temperature difference at various positions inside the fermentation chamber. At the same time, the temperature difference between the position far from the air outlet and the position directly facing the air outlet is also large. Since the air delivered by the air conditioner carries moisture and is used to adjust the humidity inside the fermentation chamber, this causes a large humidity difference at various positions inside the fermentation chamber. These conditions result in uneven fermentation of products and may even cause the problem of fermentation failure. Therefore, in order to solve the above technical problems, the technical solution of this application is set. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for regulating the internal temperature, humidity and air volume of a fermentation chamber, which solves the above technical problems.

[0005] The technical solution adopted by the present invention is as follows:

[0006] An equipment for regulating the internal temperature, humidity and air volume of a fermentation chamber, comprising a horizontally arranged fermentation chamber, in which several layers of fermentation racks are placed. A ventilation pipe is connected above the fermentation chamber, and a main air supply pipe and a main air return pipe are respectively communicated inside the ventilation pipe. One side of the inner wall of the fermentation chamber is connected with several vertically arranged secondary air supply pipes, and the several secondary air supply pipes are arranged in sequence along the length direction of the fermentation chamber. The upper ends of the several secondary air supply pipes are respectively communicated with the main air supply pipe, and the lower ends of the secondary air supply pipes are closed. Several groups of air outlets are respectively arranged on the outer wall of each secondary air supply pipe. The several groups of air outlets are arranged in sequence from top to bottom along the secondary air supply pipe and all face the position where the fermentation racks are located. Several air outlets in the same group are arranged in sequence along the position at the same height of the secondary air supply pipe. The other side of the inner wall of the fermentation chamber is connected with several vertically arranged secondary air return pipes, and the several secondary air return pipes are also arranged in sequence along the length direction of the fermentation chamber. The upper ends of the several secondary air return pipes are respectively communicated with the main air return pipe, and the lower ends of the secondary air return pipes are also closed. Several groups of air return openings are respectively arranged on the outer wall of each secondary air return pipe. The several groups of air return openings are arranged in sequence from top to bottom along the secondary air return pipe and all face the position where the fermentation racks are located.

[0007] The working principle of the present invention is as follows: By arranging a main air supply pipe and a main air return pipe inside the ventilation pipe above the fermentation chamber, the main air supply pipe is used to transport the gas with temperature and humidity generated by the air conditioner into several secondary air supply pipes. The advantage of this setting is that there are several air outlets inside the fermentation chamber, avoiding the problem of large temperature differences at different positions caused by a single existing air outlet. At the same time, several groups of air outlets are further arranged on the several secondary air supply pipes. The purpose of this setting is to reduce the temperature difference existing at different heights inside the fermentation chamber. Further, the air outlets in the same group are arranged in sequence along the same height on the secondary air supply pipe. This further makes the output gas more evenly dispersed, so that there are countless air outlets facing each position of the fermentation racks, making the temperature difference at each position inside the fermentation chamber smaller.

[0008] Meanwhile, a number of secondary return air ducts are arranged inside the fermentation chamber. The air inside the fermentation chamber is conveyed to the main return air duct through the number of return air ducts, and then conveyed back to the air conditioner through the main return air duct, which facilitates adjustment according to the actual temperature and humidity conditions in the fermentation chamber; in summer, the air temperature in the fermentation chamber is relatively low, and the return air duct conveys this part of the air back to the air handling unit, where it is mixed with a small amount of fresh air to form cold air and then sent back into the fermentation chamber, which can not only meet the refrigeration requirements of the fermentation chamber but also effectively save energy; in winter, the air can be heated and humidified to maintain the appropriate temperature and humidity in the fermentation chamber; further preferably, a number of groups of return air outlets are arranged on each secondary return air duct, and the return air outlets in the same group are arranged in sequence along the same height of the secondary return air duct. The advantage of this setting is that it facilitates efficient and uniform return air treatment at various positions inside the fermentation chamber, which further helps to reduce the temperature difference inside the fermentation chamber.

[0009] Furthermore: A number of secondary return air ducts and a number of secondary supply air ducts are arranged opposite and staggered.

[0010] Furthermore: The adjusting assembly includes an adjusting column. The outer wall of the adjusting column is in interference fit with the air outlet or the return air outlet. The front end of the adjusting column passes through one of the air outlets or the return air outlets and is connected with a baffle. The baffle is located inside the secondary supply air duct or the secondary return air duct, and the size and shape of the baffle match the size and shape of the inner wall of the secondary supply air duct or the secondary return air duct.

The upper end of the first constant air volume valve is communicated with the main supply air duct, and the lower end of the first constant air volume valve is communicated with the secondary supply air duct.

[0013] Furthermore: Second constant air volume valves are respectively arranged at the joints of the secondary return air ducts and the main return air duct. The upper end of the second constant air volume valve is communicated with the main return air duct, and the lower end of the second constant air volume valve is communicated with the secondary return air duct.

[0014] Furthermore: A number of groups of temperature and humidity monitors are respectively arranged on the inner walls on both sides in the length direction of the fermentation chamber. The number of groups of temperature and humidity monitors are arranged at equal intervals along the height direction of the fermentation chamber, and the temperature and humidity monitors in the same group are arranged in sequence along the length direction of the fermentation chamber. The temperature and humidity monitors are arranged at intervals from the secondary supply air duct or the secondary return air duct.

[0015] Furthermore: A number of secondary supply air ducts and a number of secondary return air ducts are respectively connected to the inner wall of the fermentation chamber through fixing components.

[0016] Furthermore, the fixing component includes a fixing frame and a fixing belt. The fixed end of the fixing frame is tightly connected to the inner wall of the fermentation chamber by screws. One side of the fixing belt is fixedly connected to the top of the fixing frame, and both ends of the fixing belt are tightly connected to the outer wall of the secondary air supply pipe or the secondary air return pipe through studs and nuts.

[0017] Furthermore, a coaxial air supply motor is connected between the inner walls of the main air supply pipe, and a heat dissipation fan is also connected to the inner wall of the main air supply pipe. The working end of the heat dissipation fan faces the air supply motor.

Inside the fermentation chamber 1, several layers of fermentation racks 2 are placed. Above the fermentation chamber 1, a ventilation pipe 3 is connected. Inside the ventilation pipe 3, a main air supply pipe 4 and a main air return pipe 5 are respectively communicated. On one side of the inner wall of the fermentation chamber 1, several vertically arranged secondary air supply pipes 6 are connected. The several secondary air supply pipes 6 are arranged in sequence along the length direction of the fermentation chamber 1. The upper ends of the several secondary air supply pipes 6 are respectively communicated with the main air supply pipe 4. The lower ends of the secondary air supply pipes 6 are closed. On the outer wall of each secondary air supply pipe 6, several groups of air outlets 7 are respectively arranged. The several groups of air outlets 7 are arranged in sequence from top to bottom along the secondary air supply pipe 6 and all face the position where the fermentation racks 2 are located. Several air outlets 7 in the same group are arranged in sequence along the position at the same height of the secondary air supply pipe 6. On the other side of the inner wall of the fermentation chamber 1, several vertically arranged secondary air return pipes 8 are connected. The several secondary air return pipes 8 are also arranged in sequence along the length direction of the fermentation chamber 1.

On the outer wall of each secondary air return pipe 8, several groups of air return openings 9 are respectively arranged. The several groups of air return openings 9 are arranged in sequence from top to bottom along the secondary air return pipe 8 and all face the position where the fermentation racks 2 are located. Several air return openings 9 in the same group are arranged in sequence along the position at the same height of the secondary air return pipe 8. On each group of air outlets 7 and air return openings 9, an adjusting component for adjusting the sizes of the air outlets 7 and air return openings 9 is respectively provided. The adjusting component is movably connected to one of the air outlets 7 and air return openings 9.

[0034] The specific implementation method of this embodiment is as follows: By arranging a main air supply pipe and a main air return pipe inside the ventilation pipe above the fermentation chamber, the main air supply pipe is used to transport the gas with temperature and humidity generated by the air conditioner into the several secondary air supply pipes. The advantage of this setting is that there are several air outlets inside the fermentation chamber, avoiding the problem of large temperature differences at different positions caused by a single existing air outlet. At the same time, several groups of air outlets are further provided on the several secondary air supply pipes. The purpose of this setting is to reduce the temperature difference existing at different heights inside the fermentation chamber. Further, the air outlets in the same group are arranged in sequence along the same height on the secondary air supply pipe. This further makes the output gas more evenly dispersed, so that there are countless air outlets facing each position of the fermentation rack, making the temperature difference at each position inside the fermentation chamber smaller.

[0035] Meanwhile, a number of secondary return air ducts are arranged inside the fermentation chamber. The air inside the fermentation chamber is conveyed to the main return air duct through a number of return air ducts, and then conveyed back to the air conditioner through the main return air duct, which facilitates adjustment according to the actual temperature and humidity conditions in the fermentation chamber. In summer, the air temperature in the fermentation chamber is relatively low. The return air duct sends this part of the air back to the air handling unit, where it is mixed with a small amount of fresh air to form cold air and then sent back into the fermentation chamber, which can not only meet the refrigeration requirements of the fermentation chamber but also effectively save energy. In winter, the air can be heated and humidified to maintain suitable temperature and humidity in the fermentation chamber. Further preferably, a number of groups of return air openings are arranged on each secondary return air duct, and the return air openings in the same group are arranged in sequence at the same height along the secondary return air duct. This arrangement facilitates efficient and uniform return air treatment at various positions inside the fermentation chamber, further reducing the temperature difference inside the fermentation chamber.

[0036] The adjustment components are used to make the actual outlet diameters of the air outlets at different heights of each air supply duct different. This arrangement makes the air supply volumes at different heights in the fermentation chamber approximately the same. At the same time, the adjustment components on the secondary return air duct facilitate adjusting the actual diameters of the return air openings at different heights on each secondary return air duct, making the return air volumes at different heights in the fermentation chamber approximately the same, further achieving the purpose of reducing the temperature difference inside the fermentation chamber.

[0037] Preferably, the shape of the fermentation chamber is a rectangular parallelepiped. A number of secondary air supply ducts and a number of secondary return air ducts are respectively arranged along the inner walls on both sides in the length direction of the fermentation chamber, and are used in combination with the shape of the fermentation chamber. This makes the air carrying temperature and humidity evenly released at various positions inside the fermentation chamber, and at the same time facilitates evenly recovering the air at various positions inside the fermentation chamber, making the temperature and humidity at various positions inside the fermentation chamber more uniform.

[0038] Preferably, the main air supply duct and the main return air duct are simultaneously connected to a number of fermentation chambers, which facilitates simultaneously conveying the air carrying temperature and humidity to a number of fermentation chambers, and further facilitates adjusting the temperature and humidity inside each fermentation chamber.

[0039] Preferably, a number of adjustment components are used to facilitate adjusting the size of the air outlet, and further facilitate adjusting the air volume conveyed into each fermentation chamber.

[0042] The adjustment component includes an adjustment column 10. The outer wall of the adjustment column 10 is in interference fit with the air outlet 7 or the air return port 9. The front end of the adjustment column 10 passes through one of the air outlets 7 or the air return ports 9 and is connected with a baffle 11. The baffle 11 is located inside the secondary air supply duct 6 or the secondary air return duct 8. The size and shape of the baffle 11 match the size and shape of the inner wall of the secondary air supply duct 6 or the secondary air return duct 8.

[0043] The rear end of the adjustment column 10 is provided with an adjustment handle 12. The inner wall of the adjustment handle 12 is provided with internal threads, and the outer wall at the rear end of the adjustment column 10 is provided with external threads. The adjustment handle 12 is threadedly connected with the adjustment column 10.

[0044] The specific implementation manner of this embodiment is as follows: By arranging a number of secondary air return ducts opposite to a number of secondary air supply ducts, it is convenient for them to directly face the fermentation rack, making the temperature and humidity difference around the fermentation rack smaller. At the same time, the staggered arrangement makes the temperature and humidity inside the entire fermentation chamber more uniform.

[0045] Set the adjustment column to pass through an air outlet or an air return port and be in interference fit with this air outlet or air return port. The purpose of this setting is to make it necessary for an operator to make adjustments, avoiding the problem of the adjustment column sliding along the air outlet or air return port. The baffle connected to the front end of the adjustment column is convenient for adjusting the size of the air outlet or air return port.

[0046] The adjustment handle is convenient for the operator to move the adjustment column. At the same time, the adjustment handle is threadedly connected with the adjustment column, which is convenient for further fixing the connection between the adjustment column and the air outlet or air return port.

The several groups of temperature and humidity monitors 15 are arranged at equal intervals along the height direction of the fermentation chamber 1. The temperature and humidity monitors 15 in the same group are arranged in sequence along the length direction of the fermentation chamber 1. The temperature and humidity monitors 15 are arranged at intervals from the secondary air supply duct 6 or the secondary air return duct 8.

[0051] The specific implementation method of this embodiment is: A first constant air volume valve is provided at the connection of each secondary air supply duct and the main air return duct. The first constant air volume valve distributes the wind force conveyed by the air conditioner evenly into each secondary air supply duct. The advantage of this setting is that the air carrying humidity and temperature is further evenly blown to various positions inside the fermentation.

[0052] A second constant air volume valve is provided at the connection of each secondary air return duct and the main air return duct. The second constant air volume valve enables each secondary air return duct to absorb similar air. The advantage of this setting is that the air volumes recovered from various positions inside the fermentation chamber are similar, which further makes the temperature and humidity difference inside the fermentation chamber smaller.

[0053] By arranging several temperature and humidity monitors inside the fermentation chamber, it is to fully monitor the temperature and humidity at various positions inside the fermentation chamber. When the temperature or humidity at a certain position is abnormal, it is convenient for the operator to adjust in time, so that the temperature and humidity at various positions in the fermentation chamber are similar, and finally it is convenient to meet the temperature and humidity required for fermentation.

[0058] The specific implementation method of this embodiment is: Through the fixing frame and the fixing belt, it is convenient to further fix several secondary air supply ducts and several secondary air return ducts, so that the connection between several secondary air supply ducts, several secondary air return ducts and the inner wall of the fermentation chamber is more stable.

[0059] During the operation of the air supply motor, it is convenient to drive the air inside the main air supply duct to further circulate, so as to increase the air volume delivered to each fermentation chamber, which is convenient to meet the air volume required by each fermentation chamber.
