Description

Technical Field

[0001] This utility model relates to the field of filter box technology, and in particular to a high negative pressure transparent polygonal filter box. Background Technology

[0002] In scientific research laboratories, various experiments have strict requirements for solution purity and air cleanliness. In biological experiments, cell culture and reagent preparation require the use of high-purity liquids and clean air to avoid interference from impurities and microorganisms. High-negative-pressure transparent polygonal filter boxes can provide high-precision filtration for laboratories. Their transparent characteristics allow researchers to observe the filtration process, identify problems in a timely manner, and make adjustments, which helps improve the success rate and accuracy of experiments. In addition, with the increasing global emphasis on environmental protection, countries have introduced stricter environmental regulations and emission standards. In terms of air pollution prevention and control, industrial enterprises and various places need to take effective measures to reduce exhaust emissions and lower the content of particulate matter and harmful gases in the air.

[0003] A high negative pressure filter consists of a shell, filter unit, inlet and outlet, and negative pressure generating device. It can effectively intercept and remove various impurities in the gas. Due to the high negative pressure environment involved in industrial production, ordinary filters will experience poor sealing and reduced filtration efficiency under negative pressure. For filtration systems, ordinary filters lack effective real-time monitoring methods and cannot accurately determine the degree of filter element blockage, which can lead to production interruption and equipment damage. Filters with differential pressure measurement function can monitor the pressure difference between the inlet and outlet in real time, judge the blockage of the filter element based on the pressure difference change, and remind operators to perform maintenance in time to ensure the stable operation of the system. However, the structure is complex, and cleaning and disassembly after blockage are inconvenient, requiring the use of special tools and methods, which increases the difficulty of disassembly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high negative pressure transparent polygonal filter box, which aims to improve the problems of the existing technology, such as complex structure, inconvenient cleaning and disassembly after clogging, the need for special tools and methods, and increased disassembly difficulty.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high negative pressure transparent polygonal filter box, including a filter box shell, a support frame fixedly connected to the top left side of the filter box shell, a motor fixedly connected to the top left side of the support frame, a rotating shaft fixedly connected to the output end of the motor, the right side of the rotating shaft rotatably connected to the top left side of the support frame, a steel wire rope fixedly connected to the outer wall of the rotating shaft, a hook fixedly connected to the bottom of the steel wire rope, a U-shaped frame provided at the bottom of the hook, a filter plate fixedly connected to the bottom of the U-shaped frame, a base plate fixedly connected to the bottom inner side of the filter box shell, a mounting seat fixedly connected to the top left side of the base plate, the top of the mounting seat engaging with the bottom of the filter plate, two partition plates fixedly connected to the top of the base plate, a negative pressure machine fixedly connected to the top right side of the base plate, an air extraction pipe connected to the left side of the negative pressure machine, an air outlet pipe connected to the right side of the negative pressure machine, and a connecting mechanism provided on the left side of the filter box shell for sealing connection with the pipe.

The exhaust pipe 17 ensures that the filtered gas can be discharged, thereby maintaining the negative pressure environment inside the filter box.

[0039] Working principle: When the negative pressure generator 13 generates negative pressure inside the filter box housing 1, gas impurities are intercepted and adsorbed by the filter plate 9. When cleaning is required, the U-shaped frame 8 is hung by the hook 7, and the rotating shaft 5 is driven by the motor 4. The rotation of the rotating shaft 5 causes the steel wire rope 6 to start to retract, thereby moving the filter plate 9 upward, which facilitates the cleaning of the filter plate 9 separately, and performs a more comprehensive and thorough cleaning. It can perform targeted cleaning, wiping and replacement of the gas impurities that have been intercepted and adsorbed, effectively removing impurities, restoring the filtration performance of the filter plate 9, ensuring the filtration effect, shortening the equipment downtime caused by cleaning, enabling the equipment to be put into use more frequently, and improving the availability and production efficiency of the equipment.

[0040] When the intake pipe 201 is connected to the connecting pipe 203, a preliminary threaded seal is achieved through the threaded sleeve 202. As the connecting pipe 203 is gradually tightened, the fastening sleeve 1 204 and the fastening sleeve 206 fit together to enhance the sealing effect. At this time, the fastening bolt 208 is rotated to pass through the fastening sleeve 206 and the fastening sleeve 1 204 to enhance the fixing effect. Through the combination of multi-stage sealing and fastening structure, the sealing performance of the connection is improved, which can effectively meet the gas sealing requirements under different pressure and temperature working conditions, reduce the risk of leakage, and improve the reliability and safety of the entire system.
