Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and more specifically, to an energy-saving air conditioning device for a cultural relic storage cabinet. Background Art

[0002] Cultural relic storage cabinets are used to store and protect cultural relics. They are usually placed in safekeeping areas of museums, archaeological institutes or private collectors. Since different cultural relics have different sensitivities and tolerances to the environment, inappropriate temperature and humidity can cause damage to cultural relics. Therefore, it is necessary to adjust the temperature and humidity of the storage cabinets through air conditioning devices to ensure that the temperature and humidity in the storage cabinets are the best state for the preservation of cultural relics.

[0003] Since museums and archaeological institutes preserve a large number of cultural relics, if all storage cabinets are equipped with a separate set of air conditioning devices, the purchase cost of the equipment will be greatly increased. Therefore, a "one-for-many" method is adopted to control the temperature and humidity in the storage cabinets, that is, only one set of constant temperature and humidity units is used, and multiple guide pipes 1 are connected to the air supply duct of the constant temperature and humidity unit, and the guide pipe 1 is connected to the corresponding storage cabinet, and the guide pipe 2 is connected to the storage cabinet, so that the guide pipe 2 is connected to the return air duct of the constant temperature and humidity unit. In this way, the effect of controlling the temperature and humidity in multiple storage cabinets by using only one set of constant temperature and humidity units can be achieved, and solenoid valves can be installed on each guide pipe 1 to individually control the temperature and humidity in individual storage cabinets among the multiple storage cabinets.

[0004] When a constant temperature and humidity unit is used to control the temperature and humidity in multiple storage cabinets, a longer air supply duct is required. Due to the long length of the air supply duct, in order to ensure that the gas transported in the air supply duct can be transported to the storage cabinet in time and the temperature and humidity in the storage cabinet are at the preset value, it is necessary to increase the exhaust power of the constant temperature and humidity unit or install a fan on the air supply duct to increase the flow speed of the gas in the air supply duct.

[0005] However, the above-mentioned prior art still has shortcomings. Since the flow rate of the gas in the air supply pipe is relatively fast, the flow rate of the gas once it enters the storage cabinet through the guide pipe is also relatively fast. The rapidly changing airflow will destroy the microenvironment in the storage cabinet, causing the temperature and humidity in the storage cabinet to change greatly in a short period of time, which may cause the cultural relics materials to expand or contract, easily causing damage to the cultural relics, and the use effect is not ideal. Summary of the invention

[0006] The present invention provides an energy-saving air conditioning device for a cultural relic storage cabinet, and aims to solve the following problem: the existing air conditioning device for a cultural relic storage cabinet adopts a "one-supply-many" method to regulate the temperature and humidity in the storage cabinet. Since the flow rate of the gas in the air supply pipe is relatively fast, the flow rate of the gas once entering the storage cabinet through the guide pipe is also relatively fast. The rapidly changing airflow will destroy the microenvironment in the storage cabinet, causing the temperature and humidity in the storage cabinet to change greatly in a short period of time, which may cause the cultural relic material to expand or contract, easily causing damage to the cultural relic, and the use effect is not ideal.

[0007] To achieve the above object, the present invention provides the following technical solutions: an energy-saving air conditioning device for cultural relics storage cabinets, comprising a constant temperature and humidity unit and a plurality of cultural relics storage cabinets, wherein the constant temperature and humidity unit is provided with an air supply pipe and an air return pipe; The air supply pipe is provided with a pipeline connecting component, which includes a guide pipe 1 and a guide pipe 2.

DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Refer to the instruction manual Figures 1 to 9An energy-saving air conditioning device for cultural relics storage cabinets includes a constant temperature and humidity unit 1 and a plurality of cultural relics storage cabinets 2. The constant temperature and humidity unit 1 is provided with an air supply pipe 11 and an air return pipe 12; the air supply pipe 11 is provided with a pipeline connecting component 3, and the pipeline connecting component 3 includes a guide pipe 1 31 and a guide pipe 2 34, and the guide pipe 1 31 and the guide pipe 2 34 are respectively arranged on both sides of the cultural relics storage cabinet 2. The air supply pipe 11, the guide pipe 1 31, the guide pipe 2 34 and the air return pipe 12 form a gas circulation loop; the guide pipe An airflow stabilizing mechanism 4 is arranged in the tube 31, and the airflow stabilizing mechanism 4 includes a fixed cover 41, a baffle 44 and a driving component. The fixed cover 41 is fixedly sleeved on the guide tube 31, and a buffer zone is between the fixed cover 41 and the guide tube 31. A through hole 1 311 and a through hole 2 312 are opened on the guide tube 31. The baffle 44 is rotatably arranged in the guide tube 31, and the baffle 44 is used to block the through hole 1 311. The driving component drives the baffle 44 to rotate to connect the buffer zone with the inside of the guide tube 31.

[0030] The pipeline connecting component 3 includes a solenoid valve 1 32, which is fixedly arranged on the guide pipe 1 31, a solenoid valve 3 36 is fixedly arranged on the guide pipe 2 34, a connecting pipe 111 is fixedly connected to the air supply pipe 11, and the connecting pipe 111 is fixedly connected to the return air pipe 12, and the end of the guide pipe 1 31 away from the cultural relics storage cabinet 2 is fixedly connected to the connecting pipe 111, and multiple guide pipes 2 34 are fixedly connected to the same auxiliary pipe 35, and the auxiliary pipe 35 is fixedly connected to the return air pipe 12. Multiple solenoid valves 2 33 are fixedly arranged on the connecting pipe 111, and the solenoid valves 2 33 are adapted to the solenoid valve 1 32, a fan 1 12 is fixedly arranged on the connecting pipe 111, and a fan 2 351 is fixedly arranged on the auxiliary pipe 35.

[0031] It should be noted that the constant temperature and humidity unit 1 is provided with components such as a compressor, a condenser, an expansion valve, a fan, a filter, a humidifier, a heater, a temperature and humidity sensor, a frequency converter, a circuit breaker and a controller. The treated gas air is transported to the target area (i.e., the cultural relic storage cabinet 2) through the air supply pipe 11, and the return air pipe 12 collects the gas discharged from the cultural relic storage cabinet 2 for reprocessing, thereby realizing a closed circulation system to ensure continuous monitoring and adjustment of the environmental conditions in the cultural relic storage cabinet 2. The constant temperature and humidity unit 1 is a mature prior art and will not be described in detail in this application. A plurality of cultural relic storage cabinets 2 are arranged at equal intervals in sequence, and the cultural relic storage cabinets 2 have the characteristics of high air tightness. A temperature and humidity sensor is provided in the cultural relic storage cabinet 2. The temperature and humidity sensor is used to monitor the temperature and humidity parameters in the cultural relic storage cabinet 2 in real time, and transmit the temperature and humidity information in the cultural relic storage cabinet 2 to the constant temperature and humidity unit 1, obtain the temperature and humidity, and cooperate with the constant temperature and humidity unit 1 for regulation. As a mature prior art, it will not be described in detail in this application.

[0032] It should also be noted that the guide pipe 1 31 and the guide pipe 2 34 are respectively arranged on both sides of the cultural relic storage cabinet 2, that is, the guide pipe 1 31 and the guide pipe 2 34 are symmetrically arranged on the cultural relic storage cabinet 2, and the gas transported by the air supply pipe 11 enters the cultural relic storage cabinet 2 through the guide pipe 1 31, and the original gas in the cultural relic storage cabinet 2 is discharged into the return air pipe 12 through the guide pipe 2 34, thereby realizing the convection setting of the guide pipe 1 31 and the guide pipe 2 34, which can efficiently regulate the temperature and humidity in the cultural relic storage cabinet 2.

[0033] Furthermore, the second fan 351 can also be arranged on the air return pipe 12. After the second fan 351 on the air return pipe 12 is started, it can also extract the gas in the auxiliary pipe 35, so that the gas in the cultural relic storage cabinet 2 can be discharged faster.

[0034] The specific implementation scenario is as follows: the initial state of the solenoid valve 1 32 and the solenoid valve 3 36 is a closed state. When it is monitored that the temperature and humidity in a certain cultural relic storage cabinet 2 do not meet the preset values ​​and the temperature and humidity in the cultural relic storage cabinet 2 need to be regulated, the solenoid valve 1 32 and the solenoid valve 3 36 corresponding to the cultural relic storage cabinet 2 are first started, so that the connecting pipe 111, the guide pipe 1 31, the guide pipe 2 34, the auxiliary pipe 35 and the return air pipe 12 form an air circulation passage. If the position where the guide pipe 1 31 is connected to the connecting pipe 111 and the length of the passage formed by the connecting pipe 111 are appropriate, after the gas transported by the connecting pipe 111 enters the guide pipe 1 31, it is directly input into the cultural relic storage cabinet 2 through the end of the guide pipe 1 31, and the gas in the cultural relic storage cabinet 2 is transported to the return air pipe 12 through the guide pipe 2 34, so as to achieve the effect of air circulation regulating the temperature and humidity in the cultural relic storage cabinet 2. If the length of the passage formed by the guide pipe 1 31 and the connecting pipe 111 connected on the cultural relic storage cabinet 2 is long (i.e., refer to Figure 3The interior of the cultural relic storage cabinet 2 near the bottom needs to adjust the temperature and humidity), and it is necessary to increase the power of the constant temperature and humidity unit 1 or start the fan 112 to increase the flow rate of the gas in the connecting pipe 111 to ensure that the gas can enter the corresponding cultural relic storage cabinet 2 in time. At this time, the flow rate of the gas transported in the connecting pipe 111 is relatively fast. If the gas with a fast flow rate is directly transported to the cultural relic storage cabinet 2, the microenvironment in the cultural relic storage cabinet 2 will be destroyed in a short time, causing the temperature and humidity in the storage cabinet to change greatly in a short time, which may cause the cultural relic material to expand or contract, and easily cause damage to the cultural relic. In addition, compared with the method of smoothly adjusting the air in the cultural relic storage cabinet 2, the overall energy efficiency of the system is reduced, and unnecessary energy consumption is increased. Therefore, when the gas flow rate in the guide pipe 31 is relatively large, the driving component drives the baffle 44 to rotate, so that the buffer zone and the guide pipe 31 are in contact with each other. The interiors are interconnected, and part of the gas transported in the flow guide tube 31 enters the buffer zone, and then the gas in the buffer zone enters the cultural relic storage cabinet 2 through the end of the flow guide tube 31. When the gas enters the buffer zone through the flow guide tube 31, its speed will be slowed down due to the inertia effect. According to the law of conservation of mass, the speed of the gas during the flow process is inversely proportional to the cross-sectional area of ​​its flow. Therefore, when the cross-sectional area of ​​the pipeline suddenly increases (that is, when the gas enters the buffer zone from the flow guide tube 31), the gas flow rate will decrease, so that the speed of the gas buffer zone is more uniform when flowing through the flow guide tube 31, and the design of the buffer zone can reduce the resistance and pressure loss of the gas during flow. Reducing the pressure loss helps to maintain the stability of the gas flow, making the flow rate more uniform, thereby ensuring that the gas flowing from the flow guide tube 31 into the cultural relic storage cabinet 2 is more uniform and stable.

[0035] Cultural relics such as paper, fabric, and wood are more sensitive to changes in humidity than changes in temperature. The constant temperature and humidity unit 1 is used to continuously deliver gas to the cultural relic storage cabinet 2 to achieve the purpose of regulating the temperature and humidity in the cultural relic storage cabinet 2. This working method requires the constant temperature and humidity unit 1 to work continuously, which consumes more electricity resources. The cost of electricity use remains high, and long-term electricity use requires patrol inspections by staff, otherwise the safety hazards cannot be eliminated. This solution provides another working method, which aims to protect the cultural relics in the cultural relic storage cabinet 2 while reducing the use of electricity resources to achieve energy saving and environmental protection. Furthermore, a fiber humidity-regulating sheet is placed in each cultural relic storage cabinet 2, that is, the humidity in the cultural relic storage cabinet 2 is regulated by using the fiber humidity-regulating sheet in combination with the constant temperature and humidity unit 1. Specifically, the constant temperature and humidity unit 1 is started, and gas is delivered to the cultural relic storage cabinet 2 through the air supply pipe 11. The accuracy of the fiber humidity control sheet is corrected in a short time. After the correction is completed, the constant temperature and humidity unit 1 is turned off and the power is cut off. The electromagnetic valve 1 32 and the electromagnetic valve 3 36 are closed. The high air tightness of the cultural relic storage cabinet 2 ensures accurate humidity control, and the fiber humidity control sheet alone adjusts the humidity of the cultural relic storage cabinet 2 with a wide range and low fluctuation. The high air tightness cultural relic storage cabinet 2 with a ventilation rate of less than 0.02 times / d (the unit of d is: day) can effectively reduce the impact of external humidity on the humidity in the cultural relic storage cabinet 2, reduce humidity fluctuations, and make the humidity curve in the cultural relic storage cabinet 2 more stable even if it is in a high humidity or low humidity environment for a long time. When the humidity in the cultural relic storage cabinet 2 is uniform and constant, the daily humidity adjustment amount of the fiber humidity-conditioning sheet is the gas leakage amount in the cultural relic storage cabinet 2 less than 0.02 multiplied by the internal volume of the cultural relic storage cabinet 2, the moisture absorption and release rate of the fiber humidity-conditioning sheet remains unchanged, the smaller the leakage amount, the better the humidity adjustment effect of the fiber humidity-conditioning sheet, the less moisture absorption and release amount required, and the service life of the humidity-conditioning sheet is extended. The humidity in the cultural relic storage cabinet 2 is higher than the target humidity, and the fiber humidity-conditioning sheet continuously and uninterruptedly absorbs the wet air in the cultural relic storage cabinet 2, so that the water content of the air in the cultural relic storage cabinet 2 is reduced and gradually tends to the target humidity. When the humidity in the cultural relic storage cabinet 2 is stable within the target humidity control range, the fiber humidity-conditioning sheet stops absorbing the wet air in the cultural relic storage cabinet 2. When the humidity in the cultural relic storage cabinet 2 is lower than the target humidity, the fiber humidity-conditioning sheet continuously and uninterruptedly releases wet gas, so that the water content of the air in the cultural relic storage cabinet 2 increases and gradually tends to the target humidity. When the humidity in the cultural relic storage cabinet 2 is stable within the target humidity control range, the fiber humidity-conditioning sheet stops releasing wet gas. During this process, the cultural relic storage cabinet 2 is always in a power-off state, there is no risk of electricity consumption, and no personnel are required to be on duty. When the fiber humidity control sheet works for a long time and the moisture absorption and release capacity is saturated, the humidity control accuracy deviation is too large, and the humidity control function is lost, the constant temperature and humidity unit 1 is started and operated, and the solenoid valve 1 32 and the solenoid valve 3 36 are opened. The humidity in the cultural relic storage cabinet 2 is regulated by the constant temperature and humidity unit 1, and the air in the cultural relic storage cabinet 2 is purified.The humidification and dehumidification capacity of the constant temperature and humidity unit 1 is much greater than the moisture release and absorption capacity of the fiber humidity-control sheet. Therefore, when the constant temperature and humidity unit 1 is running, the moisture absorption and dehumidification of the fiber humidity-control sheet in the cultural relic storage cabinet 2 will not interfere with its regulation. Instead, it will be activated in the relative constant temperature and humidity unit 1, modify the accuracy of the fiber humidity-control sheet, and restore the humidity control function. The constant temperature and humidity unit 1 is set to control the humidity to the target humidity of the fiber humidity-control sheet. When the humidity in the cultural relic storage cabinet 2 is greater than the target humidity, the return air pipe 12 draws back the wet air in the cultural relic storage cabinet 2, and after air purification and condensation dehumidification treatment, the dry gas approaching the target humidity is sent into the cultural relic storage cabinet 2. The fiber humidity-control sheet contacts the dry air and automatically releases the wet gas. This process is circulated, and the fiber humidity-control sheet repeatedly releases moisture, and the moisture content of the material itself decreases and gradually recovers its activity. The humidity in the cultural relic storage cabinet 2 is also affected by the dry gas sent in and gradually approaches the target. After the humidity is adjusted, the humidity remains stable; when the humidity in the cultural relic storage cabinet 2 is less than the target humidity, the constant temperature and humidity unit 1 draws back the dry air in the cultural relic storage cabinet 2, and after air purification and spray humidification treatment, the humidified gas tending to the target humidity is sent into the cultural relic storage cabinet 2, and the fiber humidity-adjusting sheet contacts the humidified gas and automatically absorbs the humidified gas. This process is circulated, and the fiber humidity-adjusting sheet repeatedly absorbs moisture, and the material's own water content increases and gradually recovers its activity. The humidity in the cultural relic storage cabinet 2 is also affected by the humidified gas sent in, and the humidity gradually tends to the target humidity and then remains stable. During the active regulation process of the constant temperature and humidity unit 1, the humidity in the cultural relic storage cabinet 2 is stabilized and the fiber humidity-adjusting sheet is activated, and the air in the cultural relic storage cabinet 2 is purified at the same time. After the humidity adjustment accuracy of the fiber humidity-adjusting sheet is modified, the activation process ends, the constant temperature and humidity unit 1 is turned off to cut off the power supply, and then the solenoid valve 1 32 and the solenoid valve 3 36 are closed, and the fiber humidity-adjusting sheet is used to adjust the humidity of the cultural relic constant humidity storage cabinet 2 alone. The repeated cycles reduce the trouble of frequent replacement of fiber humidity-conditioning sheets, while reducing energy consumption and increasing safety.

[0036] Refer to the instruction manual Figure 4 and Figure 5 When the gas flow rate in the flow guide tube 31 is relatively high, in order to be able to automatically adjust according to the gas flow rate so that the buffer zone is connected to the flow guide tube 31, specifically, the driving assembly includes an adjustment plate 42, which is slidably arranged in the flow guide tube 31, and a plurality of exhaust holes are provided on the adjustment plate 42. The same elastic member 43 is fixedly arranged between the adjustment plate 42 and the flow guide tube 31, and a connecting rod 45 is fixedly arranged on the adjustment plate 42, and the connecting rod 45 is movably arranged with the baffle 44. A connecting plate is fixedly arranged on the baffle 44, and a guide hole is provided on the connecting plate. A connecting shaft is fixedly arranged on the connecting rod 45, and the connecting shaft is movably arranged in the guide hole.

[0037] It should be noted that the elastic member 43 is configured as a spring, the spring is fixedly disposed on the adjustment plate 42 , and one end of the spring away from the adjustment plate 42 is fixedly disposed on the inner wall of the guide tube 31 .

[0038] It should also be noted that, refer to the attached Figure 7 , the gas flows from left to right through the exhaust hole in the guide pipe 31. When the flow rate of the gas is large, the gas will push the adjustment plate 42 to move to the right. When the adjustment plate 42 moves, it drives the connecting rod 45 to move and compresses the elastic member 43. The connecting shaft moves in the guide hole to drive the baffle 44 to rotate. At this time, the baffle 44 releases the blockage of the through hole 311, and the buffer zone is connected with the guide pipe 31. Part of the gas in the guide pipe 31 enters the buffer zone through the through hole 311 under the guidance of the baffle 44, and the remaining part of the gas will be directly transported to the right in the guide pipe 31 to the cultural relic storage cabinet 2. The gas flow rate in the buffer zone is reduced in the buffer zone, and then enters the guide pipe 31 through the through hole 2 312, thereby reducing the flow rate of the gas and making the gas evenly input into the cultural relic storage cabinet 2.

[0039] Refer to the instruction manual Figure 6 and Figure 7 If the gas transported in the connecting pipe 111 does not increase the power of the constant temperature and humidity unit 1 or start the fan 1 112 or the fan 2 351, the flow rate of the gas transported in the guide tube 1 31 is relatively uniform, and the gas will not push the adjustment plate 42 to move. The baffle 44 blocks the through hole 1 311. When the gas flows from left to right in the guide tube 1 31, it will enter the buffer zone when passing through the through hole 2 312. This results in part of the gas that should have directly and evenly flowed into the cultural relic storage cabinet 2 through the guide tube 1 31 entering the buffer zone through the through hole 2 312, resulting in a decrease in gas flow efficiency. To prevent the above phenomenon from occurring, specifically, a transmission plate 46 is rotatably arranged in the guide tube 1 31, and the transmission plate 46 is adapted to the through hole 2 312. Gears 47 are fixedly arranged on the transmission plate 46 and the baffle 44, and the corresponding two gears 47 are meshed. Two spoilers 48 are fixedly arranged in the guide tube 31 . The two spoilers 48 are both tiltedly arranged in the guide tube 31 . The spoilers 48 are matched with the corresponding baffles 44 .

[0040] It should be noted that the baffle plate 44 is provided with a vent hole 1 441 , the transmission plate 46 is provided with a vent hole 2 461 , and the vent hole 1 441 is matched with the vent hole 2 461 .

[0041] It should also be noted that, refer to the attached Figure 7In the initial state, the baffle plate 44 blocks the through hole 1 311, and the transmission plate 46 blocks the through hole 2 312. If the gas flowing in the guide tube 1 31 is uniform and stable, the adjustment plate 42 will not be displaced. At this time, the buffer zone and the guide tube 1 31 are in a closed state. When the air flow velocity in the guide tube 1 31 is large, the air flow pushes the adjustment plate 42 to move to the right. During the movement of the adjustment plate 42 to the right, the movement of the connecting shaft drives the baffle plate 44 to rotate, and the corresponding two gears 47 are meshed, that is, during the rotation of the baffle plate 44, the transmission plate 46 is driven to rotate synchronously. The buffer zone is connected with the guide tube 31 at this time, and part of the gas in the guide tube 31 enters the buffer zone through the through hole 311 under the guidance of the spoiler 48 and the baffle 44, and then flows out of the buffer zone through the through hole 312; the remaining part of the gas in the guide tube 31 continues to flow to the right and hits the inclined transmission plate 46, so as to further reduce the gas flow rate, and when the baffle 44 and the transmission plate 46 are inclined, the air hole 441 is connected with the air hole 461, which can increase the flow space of the gas in the guide tube 31.

[0042] Furthermore, auxiliary plates can be fixedly arranged on the baffle plate 44 and the transmission plate 46. When the baffle plate 44 and the transmission plate 46 are tilted, the auxiliary plates on the two baffle plates 44 come into contact with each other. At this time, the guide tube 31 is blocked with the cooperation of the auxiliary plate and the baffle plate 44, and the airflow can only enter the buffer zone through the through hole 311. Different from the above scheme, all airflows need to enter the buffer zone and then flow through the end of the guide tube 31 to the cultural relics storage cabinet 2, that is, the flow rate of the transported gas is completely reduced.

[0043] Refer to the instruction manual Figure 8 A fixed cover 41 is provided on the guide tube 31. The design of the buffer zone can reduce the gas flow rate in the guide tube 31. Of course, the space design of the buffer zone is very important and the larger the better. For example, if the space of the buffer zone is small, the effect of reducing the gas flow rate cannot be effectively achieved. If the space of the buffer zone is large, it is not conducive to the gas being transported from the buffer zone to the guide tube 31, which will lead to a decrease in the gas transportation efficiency. In order to be able to adjust the space of the buffer zone according to the flow rate of the airflow, and when the flow rate of the gas in the guide tube 31 is large or there is an unstable fluctuation, the gas flow rate transported in the buffer zone is further regulated. Specifically, an airflow stabilizing mechanism 2 5 is provided in the fixed cover 41. The airflow stabilizing mechanism 2 5 includes a lifting plate 51, which is slidably arranged in the fixed cover 41, and an elastic member 2 52 is fixedly arranged between the lifting plate 51 and the inner wall of the fixed cover 41. A second spoiler 53 and a third spoiler 54 are fixedly arranged in the fixed cover 41 . The second spoiler 53 and the third spoiler 54 are both located between the guide tube 1 31 and the corresponding lifting plate 51 . The second spoiler 53 and the third spoiler 54 are both tiltedly arranged in the fixed cover 41 .

[0044] It should be noted that the second elastic member 52 is configured as a spring, the spring is fixed to the lifting plate 51 , and one end of the spring away from the lifting plate 51 is fixed to the inner wall of the fixed cover 41 .

[0045] It should also be noted that after the gas in the guide tube 31 enters the buffer zone through the through hole 311, if the gas flow rate is fast, it will push the lifting plate 51 to move toward the side away from the guide tube 31. At this time, the elastic member 2 52 is compressed and deformed, and the space in the buffer zone increases. The gas entering the buffer zone will flow through and hit the spoiler 2 53 and the spoiler 3 54. The inclined spoiler 2 53 and the spoiler 3 54 can change the flow direction of the gas in the buffer zone, thereby reducing the flow rate of the gas.

[0046] Refer to the instruction manual Fig. 9 In order to further reduce the gas flow rate, specifically, a return pipe 55 is fixedly provided in the guide pipe 31, and one end of the return pipe 55 away from the guide pipe 31 is fixedly connected to the fixed cover 41.

[0047] It should be noted that a guide plate is fixedly arranged at an angle in the guide tube 31, and the guide plate is matched with the end of the return pipe 55, so that part of the gas in the guide tube 31 is introduced into the return pipe 55, and the return pipe 55 then transports the gas to the buffer zone, so that the gas passes through the spoiler of the spoiler 2 53 and the spoiler 3 54 to reduce the flow speed.

[0048] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
