Technical Field
[0001] The utility model relates to the technical field of air filtration, in particular to an air filtration and purification system. Background Art
[0002] A gas filter is a device used to remove solid impurities, liquid droplets and other pollutants from gases. It is widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electricity, urban water supply and other fields. The principle of a gas filter is mainly to use filter materials to filter the gas and retain impurities in the gas inside the filter, thereby achieving the purpose of purifying the gas.
[0003] In the existing air filtration system, in order to improve the filtration efficiency, water removal, dust removal and oil removal devices are specially added to the system. The function of these devices is to further purify the air and remove impurities therein. However, these devices will inevitably produce various dirt during continuous operation. These dirt are mainly deposited downward by their own gravity. The system is usually equipped with a sewage pipe to discharge these deposited dirt. However, a problem often encountered in the sewage discharge process is pipe blockage. In order to prevent the sewage pipe from being blocked and affecting the normal operation of the system, the user needs to regularly check and clean the sewage pipe to ensure that the sewage discharge is unobstructed, which reduces the convenience of using the air filtration system. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide an air filtration and purification system to solve the technical problem that pipeline blockage is often encountered during sewage discharge, which reduces the convenience of using the air filtration system.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air filtration and purification system, comprising a device housing, a back plate and a mounting plate, the mounting plate is provided with an oil-water separator, a precision filter, a water removal device, a dust removal device and an oil removal device, the bottom ends of the water removal device, the dust removal device and the oil removal device are all provided with a drain valve, and a cleaning mechanism is provided on one side of the water removal device;
[0006] The cleaning mechanism comprises an air pump, one side of the air pump is provided with an air inlet hole and a high-pressure air hole, and one side of the high-pressure air hole is connected with a high-pressure air pipe.
[0007] By adopting the above technical solution, after the air pump is started, the outside air can be sucked in through the air inlet and pressurized to form high-pressure gas. The high-pressure gas then enters the interior of the sewage pipe through the high-pressure air pipe and the branch pipe to perform high-pressure cleaning on the sewage pipe. Such operation can effectively remove oil, water and dirt in the sewage pipe and prevent them from stopping flowing in the sewage pipe, thereby avoiding blockage of the sewage pipe.
[0008] Furthermore, a sewage pipe is provided at the bottom end of the sewage valve, and the high-pressure air pipe is connected to the sewage pipe through a branch pipe.
[0009] By adopting the above technical solution, it is possible to ensure that the waste liquid and waste water generated during the filtration process are discharged smoothly from the system, which helps to keep the filtration system clean and operate efficiently, and prevents the waste liquid and waste water from accumulating inside the system, thereby affecting the filtration effect and system life.
[0010] Furthermore, the ends of the three sewage pipes are connected to each other and are provided with a four-way valve, and the four-way valve is connected to an external sewage storage device.
[0011] By adopting the above technical solution, three sewage pipes are gathered into one outlet through a four-way valve to realize centralized sewage discharge. This design simplifies the layout of sewage pipes and reduces the complexity of installation and maintenance. At the same time, the connection between the four-way valve and the external sewage storage device ensures that the waste liquid and wastewater generated by the filtration system can be safely and effectively collected and treated.
[0012] Furthermore, an air inlet and an air outlet are respectively arranged on the left and right sides of the device housing, and the air outlet is connected to external equipment through a quick connector.
[0013] By adopting the above technical solution, the air inlet and the air outlet are respectively arranged on the left and right sides of the device shell, so that the gas can flow in and out smoothly, which helps to improve the processing efficiency of the filtration system.
[0014] Furthermore, the water removal device, dust removal device and oil removal device are arranged linearly and equidistantly, and are detachably connected to the mounting plate by bolts.
[0015] By adopting the above technical solution, the flow path of the gas through the three devices is ensured to be uniform, which is conducive to maintaining a stable filtering effect. At the same time, this arrangement is also easy to install and maintain, allowing staff to more conveniently access and operate each device.
[0016] Furthermore, a straight groove is provided on the surface of the mounting plate, and the mounting plate is detachably connected to the back plate by bolts.
[0017] By adopting the above technical solution, the straight groove provides installation space for the bolts, so that the mounting plate can be firmly connected to the back plate. This connection method is simple and reliable, ensuring the structural stability of the filtering system.
[0018] Furthermore, the air inlet, the oil-water separator, the precision filter, the water removal device, the dust removal device, the oil removal device and the air outlet are connected in sequence through an air pipe.
[0019] By adopting the above technical solution, this connection method ensures that the gas can pass through each filtering device in sequence according to the set path, thereby realizing comprehensive purification of the gas. The gas entering from the air inlet undergoes oil-water separation, precision filtration, water removal, dust removal and oil removal in sequence, and is finally discharged from the air outlet, ensuring the cleanliness of the gas.
[0020] Furthermore, the high-pressure air pipe, branch drain pipe and air supply pipe are all made of PVC hose.
[0021] By adopting the above technical solutions, the PVC hose has good flexibility and durability, can easily cope with the bending and vibration in the system, and ensure the smooth transmission of gas and waste liquid. The PVC material also has good corrosion resistance and can resist the erosion of various chemicals, thereby extending the service life of the pipeline.
[0022] Furthermore, the device housing, back plate and mounting plate are all made of stainless steel.
[0023] By adopting the above technical solution, the stainless steel material has excellent corrosion resistance and can resist the erosion of chemical substances in gas and waste liquid, ensuring that the device housing, back plate and mounting plate are not easily damaged during long-term use.
[0024] Furthermore, the precision filter is an SMC precision filter.
[0025] By adopting the above technical solutions, SMC precision filters have efficient filtering performance and can accurately remove fine impurities and particulate matter in the gas to ensure the purity of the output gas. At the same time, as a well-known brand, SMC's precision filters have been widely recognized for their quality and stability.
[0026] In summary, the utility model mainly has the following beneficial effects:
[0027] 1. The utility model uses a cleaning mechanism. After the air pump is started, first, the outside air is sucked into the air pump through the air inlet hole, and is pressurized inside the air pump to form high-pressure gas. This step provides the necessary high-pressure gas source for the subsequent cleaning operation. At the same time, the high-pressure gas is passed into the interior of the sewage pipe through the high-pressure gas pipe and the branch pipe. The introduction of the high-pressure gas performs high-pressure cleaning on the interior of the sewage pipe, effectively preventing the oil and water dirt from stopping flowing inside the sewage pipe, thereby avoiding the blockage of the sewage pipe. This design not only improves the sewage discharge efficiency, but also ensures the continuous and stable operation of the filtration system, reduces the user's frequent cleaning of the sewage pipe, and improves the convenience of use;
[0028] 2. The utility model provides a mounting plate which can be easily removed from the back plate. This design greatly simplifies the maintenance process of the system.

At the same time, this design also facilitates the replacement of parts. If a part is damaged or needs to be upgraded, the staff can quickly remove the mounting plate and replace the corresponding part without disassembling the entire system, thereby reducing the replacement cost and the difficulty of operation.
