Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a cleaning device. Background Art

[0002] The air contains impurities such as dust. If the air compressor directly inhales the air, the impurities will damage the blades and cylinders of the air compressor, and will also cause blockage of valves and pipelines. Therefore, an air filter needs to be installed on the inlet pipe of the air compressor to remove impurities in the air.

[0003] In this application, the air filter is usually a self-cleaning air filter, which has multiple filter cartridges and a built-in back-flushing cleaning system. That is, the filter cartridges do not need to be disassembled and can be automatically cleaned. The back-flushing cleaning system is controlled by a PLC, and the back-flushing interval and self-cleaning time can be set. The back-flushing self-cleaning process is intermittent, with only 1 to 2 groups of filter cartridges in the self-cleaning state at a time, while the other groups are still working. In this way, the accumulated dust blown down is adsorbed onto the working filter cartridge surface, making it impossible to effectively clean the dust and other impurities on the filter cartridge, thereby causing the air filter's filtering effect to deteriorate.

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of the present application.

[0041] As shown in the drawings, Figure 1 The cleaning device includes a fixed shell 10, a communication pipe 20 and a cleaning assembly 30. The fixed shell 10 has a containing cavity 11, an air inlet and a dust outlet 12. The air inlet and the dust outlet 12 are both in communication with the containing cavity 11. The containing cavity 11 is used for placing a filter cartridge 100. The air inlet is arranged correspondingly to the filter cartridge 100 and is used for conveying a purge gas. The communication pipe 20 has a gas inlet 21 and a gas outlet 22 which are in communication with each other. The gas inlet 21 is in communication with the containing cavity 11. The cleaning assembly 30 includes a shell 31 and a spraying structure 32. The shell 31 has a sewage outlet 311, an air outlet 312 and a cleaning cavity 313. The sewage outlet 311 and the air outlet 312 are both in communication with the cleaning cavity 313. The air outlet 312 is located at the top of the shell 31. The gas outlet 22 is in communication with the cleaning cavity 313. The spraying structure 32 is arranged in the cleaning cavity 313. The spraying structure 32 is used for cleaning the gas discharged by the gas outlet 22. The sewage outlet 311 is used for discharging sewage.

[0042] By applying the technical solutions of the present application, the filter cartridge 100 is located in the containing cavity 11. The purge gas conveyed by the air inlet can blow the filter cartridge 100 to remove dust and other impurities on the filter cartridge 100. The blown-off impurities are discharged by the dust outlet 12. The dust-containing gas enters the cleaning cavity 313 through the gas inlet 21 and the gas outlet 22. The spraying structure 32 cleans the dust-containing gas. The cleaned sewage is discharged by the sewage outlet 311. The cleaned gas is discharged by the air outlet 312. In this way, the cleaning device can effectively remove the dust on the filter cartridge 100 and purify the dust-containing air, thereby reducing environmental pollution. At the same time, the service life of the filter cartridge 100 can be improved, the filtering cost can be reduced, and the dust-containing air can be prevented from entering the air compressor, thereby preventing the flow-through components of the air compressor from being blocked. The design of the dust outlet 12 and the sewage outlet 311 enables the dust and other impurities and the sewage to be collected and treated separately, thereby avoiding the dust and other impurities from being mixed with the spraying water, reducing the difficulty of treating the sewage, and further reducing the difficulty of cleaning the shell 31.

[0043] Specifically, in the present application, a fan 23 is provided on the connecting pipe 20 , and the fan 23 can drive the dust-laden gas to flow from the gas inlet 21 to the gas outlet 22 .

[0044] In the prior art, some air filters are manually cleaned and dust-blown. After the system is shut down, the filter cartridge 100 is taken offline and the air source is connected to the outer surface for cleaning. However, this method pollutes the working environment. In the present application, the dust-laden air is transported to the cleaning chamber 313 for cleaning, thereby avoiding pollution of the working environment and ensuring the health of the workers.

[0045] Furthermore, a support plate 40 is provided within the accommodating chamber 11. The support plate 40 is provided with a plurality of through-holes. The support plate 40 divides the accommodating chamber 111 into a fixed chamber 111 and a storage chamber 112. The fixed chamber 111 is located above the storage chamber 112 and is used to house the filter cartridge 100. The air inlet and gas inlet 21 are connected to the fixed chamber 111. The dust outlet 12 is connected to the storage chamber 112. The support plate 40 is used to support personnel. Dust and other impurities can pass through the through-holes.

[0046] By dividing the accommodating chamber 11 into a fixed chamber 111 and a storage chamber 112, the upper fixed chamber 111 is specifically used to accommodate the filter cartridge 100, while the lower storage chamber 112 can be used to collect dust and other impurities discharged during the cleaning process. This design not only improves space utilization efficiency, but also facilitates centralized dust processing, reducing environmental pollution caused by cleaning work.

[0047] Furthermore, the support plate 40 allows workers to more easily access the filter cartridge 100 for inspection, cleaning, and replacement without having to disassemble the entire device or move the filter cartridge 100, simplifying the operation process and reducing maintenance costs. Furthermore, the support plate 40 itself serves as a safety platform for workers, preventing the risk of slipping or falling during the cleaning process.

[0048] Specifically, the fixed shell 10 is provided with holes through which workers can pass.

[0049] The dust discharge port 12 is provided at the bottom of the storage cavity 112 , and the cross-sectional area of ​​the storage cavity 112 gradually decreases in the direction approaching the dust discharge port 12 . A dust discharge valve 13 is provided at the dust discharge port 12 .

[0050] With this arrangement, since the dust discharge port 12 is located at the bottom of the storage cavity 112 , it can ensure that dust and other impurities naturally settle to the vicinity of the dust discharge port 12 under the action of gravity, which facilitates centralized dust discharge and improves dust discharge efficiency.

[0051] Furthermore, the design of the gradually decreasing cross-sectional area of ​​the storage chamber 112 helps to form a natural channel for impurities to slide down, thereby reducing the accumulation of impurities on the inner wall of the storage chamber 112 and avoiding the resuspension of dust and secondary pollution.

[0052] At the same time, the provision of the dust exhaust valve 13 makes the dust exhaust operation more convenient, and the dust exhaust valve 13 can be opened regularly to exhaust dust, thereby improving the degree of automation of the cleaning device.

[0053] The cleaning device further includes an air inlet pipe 50 and a venturi 60. One end of the air inlet pipe 50 is used to deliver purge gas, and a first valve 51 is provided on the air inlet pipe 50. The venturi 60 is disposed at the air inlet, with one end of the venturi 60 communicating with the other end of the air inlet pipe 50, and the other end of the venturi 60 corresponding to the interior of the filter cartridge 100.

[0054] With such an arrangement, the first valve 51 on the air inlet pipe 50 can accurately control the flow rate and pressure of the purge gas, thereby ensuring the effectiveness and safety of the purge process.

[0055] Furthermore, the shape of the venturi tube 60 can accelerate and guide the airflow. When the purge gas passes through the venturi tube 60 , its flow rate increases, forming a high-speed airflow, which helps to more thoroughly remove impurities such as dust on the surface of the filter cartridge 100 .

[0056] Furthermore, the venturi tube 60 corresponds to the interior of the filter cartridge 100 , which can improve the cleaning effect of the filter cartridge 100 , prevent impurities from being retained in the filter cartridge 100 , and prevent local surface damage of the filter cartridge 100 .

[0057] Furthermore, in the present application, the air intake pipe 50 includes a plurality of delivery pipes, each of which is provided with a first valve 51, a plurality of filter cartridges 100 are provided in the fixed shell 10, the plurality of delivery pipes are provided in a one-to-one correspondence with the plurality of filter cartridges 100, the fixed shell 10 has a plurality of air inlets, the plurality of air inlets are provided in a one-to-one correspondence with the plurality of filter cartridges 100, and a venturi tube 60 is provided between the air inlet and the corresponding filter cartridge 100. Such a setting can further improve the cleaning efficiency of the filter cartridge 100.

[0058] The gas inlet 21 is located in the accommodating chamber 11 and a filter is provided at the gas inlet 21. This arrangement further reduces dust and other impurities entering the cleaning chamber and prevents the connecting pipe 20 from being blocked.

[0059] Specifically, the spray structure 32 is located above the gas outlet 22 , and a packing layer 33 is provided between the spray structure 32 and the gas outlet 22 . Along the extension direction of the connecting pipe 20 , the cross-sectional area of ​​the gas outlet 22 gradually increases in a direction away from the gas inlet 21 .

[0060] In this configuration, the spray structure 32 is positioned above the gas outlet 22, ensuring that the spray water evenly covers the gas discharged from the gas outlet 22, fully contacting the gas and effectively cleaning it. The presence of the packing layer 33 increases the gas-liquid contact area and improves the exchange efficiency at the gas-liquid interface, thereby more effectively removing impurities such as dust from the gas.

[0061] Furthermore, the design of gradually increasing the cross-sectional area of ​​the gas outlet 22 helps to reduce the resistance of the airflow when passing through the gas outlet 22, so that the airflow can pass through more smoothly.

[0062] Furthermore, the spray structure 32 includes a water pipe 321, multiple nozzles 322, and a water pump 323. The water pipe 321 has a first end and a second end that are opposite each other. The first end of the water pipe 321 is located within the cleaning chamber 313, and a water flow regulating valve is provided on the water pipe 321. Multiple nozzles 322 are provided at the first end of the water pipe 321 and are in communication with the first end of the water pipe 321. The water pump 323 is in communication with the second end of the water pipe 321.

[0063] In this manner, the design of the multiple nozzles 322 can ensure that the gas discharged from the gas outlet 22 in the cleaning chamber 313 is sprayed evenly, thereby avoiding the problem of uneven cleaning.

[0064] Furthermore, the addition of the water pump 323 can increase the water pressure, thereby increasing the velocity of the water flow ejected from the nozzle 322 and enhancing the cleaning force, thereby more effectively removing impurities such as dust carried in the gas and improving the cleaning efficiency.

[0065] At the same time, the setting of the water flow regulating valve can accurately control the water consumption of the spray structure 32, avoiding excessive water consumption. While ensuring the cleaning effect, it realizes the rational use of water resources and meets the requirements of environmental protection and economy.

[0066] Among them, the shell 31 has a water storage part 314, the water storage part 314 is located below the gas outlet 22, the water storage part 314 is connected to the sewage outlet 311, the sewage outlet 311 is located at the bottom of the water storage part 314, the cross-sectional area of ​​the water storage part 314 gradually decreases in the direction approaching the sewage outlet 311, and a sewage valve is provided at the sewage outlet 311.

[0067] In this way, the water storage portion 314 can effectively collect the washing water falling from the filler layer 33 or the nozzle 322, avoiding waste of water resources, and also facilitating subsequent water treatment or recycling, thereby improving water utilization efficiency.

[0068] Since the cross-sectional area of ​​the water storage portion 314 gradually decreases and the sewage outlet 311 is located at the bottom, this design utilizes the effect of gravity, making it easier for water and impurities to gather near the sewage outlet 311, facilitating centralized discharge and improving drainage efficiency.

[0069] Furthermore, the design of the cross-sectional area variation of the water storage portion 314 helps prevent water and impurities from adhering to the inner wall of the water storage portion 314 , thereby facilitating subsequent cleaning of the housing 31 .

[0070] Specifically, the cleaning device further includes a connecting pipe 34 , one end of which is connected to the water storage portion 314 , and the other end of which is used to be connected to the water collection tank. A control valve is provided on the connecting pipe 34 .

[0071] With such an arrangement, the liquid level height of the water storage part 314 can be controlled by the connecting pipe 34 and the water collection tank to avoid the liquid level being too high and causing the gas outlet 22 to be immersed in water, to avoid the liquid level being too low and affecting the cleaning effect of the dust-laden gas, and at the same time to avoid the liquid level being too low and causing dust resuspension and secondary pollution.

[0072] At the same time, the control valve includes a second valve 341, a third valve 342 and a fourth valve 343 arranged in sequence, and the second valve 341 is arranged close to the water storage part 314. Such an arrangement can ensure the control effect of the connecting pipe 34.

[0073] The cleaning device also includes a protective pipe 35, both ends of which are connected to the connecting pipe 34. One connection between the protective pipe 35 and the connecting pipe 34 is located on the side of the second valve 341 close to the water storage portion 314, and the other connection between the protective pipe 35 and the connecting pipe 34 is located on the side of the fourth valve 343 away from the water storage portion 314. A protective valve 351 is provided on the protective pipe 35. When one or more of the second valve 341, the third valve 342, and the fourth valve 343 are damaged, the second valve 341, the third valve 342, and the fourth valve 343 can be closed and the protective valve 351 can be opened. This configuration can ensure the normal operation of the connecting pipe 34.

[0074] The top of the shell 31 is provided with an exhaust pipe 315 , one end of the exhaust pipe 315 is connected to the exhaust port 312 , and the other end of the exhaust pipe 315 has a bent portion.

[0075] Such a configuration can effectively prevent rainwater or foreign matter from directly entering the housing 31 from the exhaust port 312, thereby protecting the interior of the device from being affected by the external environment and extending the service life of the device.
