Background Technology

[0002] Patent CN116498176A, entitled "An Isolation Device for Material Transfer in a Clean Environment," discloses a rectangular frame divided into upper and lower sections by a mounting plate. An isolation chamber is located in the upper section, and a control mechanism is located in the lower section. The isolation chamber is opened and closed via a lifting door, and ultraviolet lamps are used within the isolation chamber for disinfection and sterilization to separate the two spaces. However, existing isolation devices with the above structure have the following problems. 1) Because the material conveying port is blocked by the conveyor line, simple blocking doors or open passage designs will leave large gaps, which cannot effectively prevent external pollutants from entering the filling room with the air, resulting in the filling room being contaminated. 2) The material conveying ports of the filling room and the packaging workshop are mostly designed with simple shielding doors or open channels, which cannot effectively prevent alcohol vapor in the filling room from spreading to the packaging workshop through the conveying ports, causing the alcohol vapor concentration in the packaging workshop to reach the explosion limit and causing a safety accident. 3) Existing air curtains and other isolation devices introduce air that has not been filtered or purified, which may affect the clean air in the filling room; at the same time, their air volume cannot be automatically adjusted, and the air volume may be too small to achieve the isolation effect.

[0017] like Figure 1This invention provides an air isolation device for beverage filling rooms that effectively isolates contaminated external air from entering the filling room and effectively reduces the risk of explosion due to excessive alcohol vapor concentration in the packaging workshop. The air isolation device includes a belt conveyor system and a filling room connected to the product packaging workshop. A conveying channel is provided on the wall connecting the filling room and the product packaging workshop. The two ends of the belt conveyor system passing through the conveying channel are located in the filling room and the product packaging workshop, respectively. The air isolation device also includes an isolation frame 1 and a clean air conveying system. The isolation frame 1 is arranged circumferentially on each wall of the conveying channel. The pressurized gas outlet of the clean air conveying system is connected from the top of the isolation frame 1 to the space inside the frame 1. During the air isolation process of the conveying channel, the space inside the frame is filled with clean air output from the clean air conveying system. The technical solution provided in this application involves setting up an isolation frame within the conveying channel between the filling room and the product packaging workshop, and then installing a clean air conveying system within this isolation frame. The pressurized gas outlet of the clean air conveying system is connected to the internal space of the isolation frame from the top. During the air isolation process in the conveying channel, the internal space is filled with clean air output from the clean air conveying system. Thus, as the filled bottles are conveyed out of the filling room, gases containing alcohol vapor can be effectively prevented from escaping into the packaging workshop. Furthermore, even if gas enters the filling room, it is treated and clean, thereby minimizing the risk of explosion and maximizing the cleanliness of the filling room.

[0018] At this time, in order to monitor the filling of the space within the isolation frame with pressurized air and adjust it according to the monitoring results, the air isolation device of this application also includes a wind pressure monitoring and adjustment control mechanism. At least on the bottom edge of the isolation frame 1, a wind pressure detection structure of the wind pressure monitoring and adjustment control mechanism is arranged. The control end of the clean air delivery system is connected to the wind pressure monitoring and adjustment control mechanism. The amount of clean air input into the space within the frame by the clean air delivery system is determined by adjusting the clean air delivery system according to the gas pressure monitored by the wind pressure detection structure in cooperation with the wind pressure monitoring and adjustment mechanism. In a preferred embodiment, the wind pressure monitoring and adjustment control mechanism further includes an automatic control valve 2 and a programmable central control module 3. The wind pressure detection structure includes at least a micro differential pressure gauge 4 and an in-frame micro-pressure ventilation pipe 5. The air inlet of the in-frame micro-pressure ventilation pipe 5 is located on the bottom edge of the isolation frame 1, and the air outlet of the in-frame micro-pressure ventilation pipe 5 is connected to the micro differential pressure gauge 4. The control terminals of both the automatic control valve 2 and the micro differential pressure gauge 4 are connected to the programmable central control module 3. The amount of air output by the clean air delivery system is determined by the automatic control valve 2 based on the wind pressure monitored by the micro differential pressure gauge 4 and controlled by the output commands of the programmable central control module 3. The wind pressure detection structure also includes a filling room micro-pressure ventilation pipe 6. The air inlet of the filling room micro-pressure ventilation pipe 6 is connected to the inner cavity of the filling room, and the air outlet of the filling room micro-pressure ventilation pipe 6 is connected to the micro differential pressure gauge 4.

[0019] Furthermore, considering the actual conditions of the packaging workshop, and to facilitate the input of compressed air and maximize its cleaning effect, the clean air delivery system of this application includes at least a duct 7 and a high-efficiency filter 8. The high-efficiency filter 8 is arranged on the inner side of the top of the isolation frame. Compressed air, after being cleaned by the high-efficiency filter 8, enters the space within the frame through the duct 7 and fills the space. The automatic control valve 2 of the air pressure monitoring and adjustment control mechanism is arranged on the duct 7. In this case, the compressed air can be either the compressed air system in the product packaging workshop or an air compressor. The gas input end of the duct 7 is connected to either the compressed air system or the air compressor.

[0020] Meanwhile, to minimize the entry of unclean air from the packaging workshop into the filling room, this application also provides an air guide structure on the end face of the isolation frame facing the filling room. Clean air within the frame is then introduced into the filling room with the assistance of the air guide structure. A preferred structure is an inclined conical surface on each end face of the isolation frame's edge. More specifically, each inclined conical surface is inclined at an angle of 15-30 degrees towards the interior space of the frame.

[0021] In summary, the technical solution provided in this application also has the following advantages: 1) By setting up an isolation frame and sealing it with the material conveying port, fresh air filtered by a high-efficiency filter is introduced into the material conveying port to form an air isolation chamber, which effectively prevents alcohol vapor in the filling room from spreading to the packaging workshop through the conveying port, avoiding safety accidents caused by alcohol vapor concentration reaching the explosion limit, and significantly improving production safety. 2) The air isolation chamber prevents dusty air from the packaging workshop from flowing back into the filling room, maintaining a clean air environment in the filling room, ensuring the cleanliness of the health wine after filling and before sealing, and improving product quality and safety. 3) Through the cooperation of the differential pressure detection unit and the control unit, precise pressure control of the isolation chamber relative to the filling chamber is achieved, avoiding pressure fluctuations caused by untimely manual adjustment, which affects the isolation effect and improves the stability and controllability of the production process; 4) The design of the detachable high-efficiency filter facilitates regular replacement and maintenance, reduces maintenance costs, and extends the service life of the equipment; at the same time, the sealing strip further enhances the sealing performance of the isolation chamber and prevents air leakage. 5) Through the automated control unit, the isolation device can be operated intelligently without human intervention, which improves production efficiency and reduces the intensity of manual labor.

[0022] The technical solution of this application will be further described below through specific embodiments: The purpose of this invention is to provide a device and system with a simple structure, high degree of automation, and accurate control of clean air delivery volume to achieve air isolation. To achieve the above objective, this invention adopts the following technical solution: The main components of the system are: isolation frame, high-efficiency filter, air duct, automatic control valve, micro differential pressure gauge, micro differential pressure gauge ventilation duct 1 (inside the isolation chamber), micro differential pressure gauge ventilation duct 2 (inside the filling room) and control unit.

[0023] The isolation frame is a rectangular structure made of 304 stainless steel, suitable for installation at the material conveying port between the filling room and the packaging workshop. The edges of the frame are sealed to the wall with sealant to form an independent air isolation chamber. The top inner wall of the isolation frame has a rectangular opening for installing a high-efficiency filter, and the other inner walls have a first conical surface that gradually tapers inward from top to bottom. The cone angle of the first conical surface is 15-30 degrees to guide the airflow.

[0024] The high-efficiency filter is a HEPA high-efficiency air filter with a filtration efficiency of not less than 99.97%. It can be detachably installed at the top opening of the isolation frame to filter the air supplied by the air conditioning purification unit. After filtration, the fresh air is sent downward and dispersed to both sides to isolate the air in the filling room and packaging workshop.

[0025] One end of the duct connects to the air conditioning purification unit, and the other end is connected to the high-efficiency filter mounting frame, used to transport the fresh air generated by the air conditioning purification unit. Conveyor belt. The automatic control valve transmits data to the automatic control unit and is controlled by differential pressure, opening and closing based on changes in differential pressure.

[0026] The micro differential pressure gauge is used to detect the pressure difference between the isolation chamber and the filling chamber within the isolation frame in real time, and to transmit the pressure difference data to the control unit in real time.

[0027] The ventilation pipe 1 of the micro differential pressure gauge opens at the bottom of the isolation chamber.

[0028] The opening of the micro differential pressure gauge ventilation pipe 2 is located on the outside of the isolation frame near the filling room.

[0029] The control unit is the control center of the entire air isolation system. After the operator sets the parameters, it can automatically run according to the program.

[0030] Example 1 An air isolation device for a health wine bottling room mainly consists of an isolation frame, a high-efficiency filter, an air duct, an automatic control valve, a differential pressure gauge, a differential pressure gauge ventilation pipe 1 (inside the isolation chamber), a differential pressure gauge ventilation pipe 2 (inside the bottling room), and a control unit. The system can achieve automatic operation and automatically adjust the air supply volume.

[0031] The isolation frame is a rectangular structure made of 304 stainless steel, suitable for installation at the material conveying port between the filling room and the packaging workshop. The edges of the frame are sealed to the wall with sealant to form an independent air isolation chamber. The top inner wall of the isolation frame has a rectangular opening for installing a high-efficiency filter, and the other inner walls have a first conical surface that gradually tapers inward from top to bottom. The cone angle of the first conical surface is 15-30 degrees to guide the airflow.

[0032] The high-efficiency filter is a HEPA filter, which can be detachably installed in the top opening of the isolation frame (1) through a snap-fit ​​structure. Its air inlet end is sealed to the rectangular air duct. The secondary clean air is filtered by the high-efficiency filter to reach the clean air standard and is delivered into the air isolation chamber.

[0033] Automatic control valves are installed on rectangular air ducts. They transmit data information with the control unit and are controlled by differential pressure. They open, open wider, close less, and close by changing the differential pressure, thereby realizing the delivery of secondary clean air and controlling the delivery volume.

[0034] The differential pressure gauge is fixed inside the control box on the outer wall of the isolation chamber of the isolation frame. The ventilation port of the differential pressure gauge ventilation pipe 1 is located on the bottom side wall of the inner wall of the isolation chamber, and the ventilation port of the differential pressure gauge ventilation pipe 2 is located on the outer side wall of the right side of the isolation chamber. The differential pressure data is transmitted to the controller in real time through the transmission line.

[0035] The control unit uses a PLC controller, which is installed on the left outer wall of the isolation frame and is connected to the automatic control valve and the micro differential pressure gauge. It is the control center of the air isolation device in the entire health wine bottling room. After the management personnel set the parameters, it can run automatically according to the program.

[0036] In summary, this application provides an air isolation device for a health wine bottling room. Through precise differential pressure monitoring and intelligent airflow adjustment, it effectively isolates the airflow between the bottling room and the adjacent packaging workshop, ensuring that alcohol vapor in the bottling room does not escape into the packaging workshop. At the same time, it prevents pollutants from the outside of the packaging workshop from entering the bottling room with the air and causing pollution, thereby improving product quality and production safety.

[0037] In implementing this utility model, a micro differential pressure gauge is first installed. The vent of the micro differential pressure gauge ventilation pipe 1 is located on the bottom side wall of the inner wall of the isolation chamber, and the vent of the micro differential pressure gauge ventilation pipe 2 is located on the right outer side wall of the isolation chamber. These are used to detect the pressure difference between the isolation chamber and the filling room. The micro differential pressure gauge is then connected to the control unit. After the control unit is activated, it controls the automatic valve to begin supplying air. The micro differential pressure gauge monitors the pressure difference between the isolation chamber and the filling room in real time: when the pressure difference is less than a certain set value, the control unit controls the automatic valve to increase its opening, increasing the airflow through the duct and raising the air pressure in the isolation chamber; when the pressure difference reaches a certain set value, the automatic valve decreases its opening, reducing the airflow. Ultimately, this maintains a stable positive pressure value between the isolation chamber and the filling room, effectively isolating the air from the filling room and the external packaging workshop.
