Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning devices, and more specifically, to an automatic cleaning device for an FFU filter element. Background Art
[0002] FFU filters, also known as FFU (Fan Filter Unit) HEPA filters or HEPA filters, are core components in modern air purification technology, playing a crucial role in filtering out airborne pollutants such as tiny particles, dust, pollen, bacteria, and even viruses. They are widely used in hospital operating rooms, laboratories, precision manufacturing workshops, data centers, and high-end residential locations, all of which require extremely high levels of environmental cleanliness.
[0003] To ensure that the FFU system can continuously and effectively provide clean air, regular maintenance and cleaning of the filter element is particularly important. However, the mainstream filter element cleaning methods currently on the market—whether using high-pressure water guns for water washing or air guns for air washing—face a common challenge: these operations are highly dependent on manual execution, which is not only labor-intensive but also poses significant safety risks.
[0004] While high-pressure water jets can effectively remove stubborn dirt from the filter element's surface during the water washing process, the resulting splash of tiny water droplets and dust particles quickly spreads into the air, causing secondary pollution. This not only affects the quality of the working environment but can also harm the respiratory system of on-site workers. Furthermore, drying the filter element after water washing is a tedious and time-consuming task. Improper handling can cause the filter element to mold or deform, affecting its filtration performance and service life.
[0005] While air washing avoids the use of water and reduces the risk of secondary contamination, it also requires close-up manual operation and may not be as effective as water washing for deeply embedded pollutants. Furthermore, the high-pressure airflow may also disperse some pollutants into the air, increasing dust concentration in the work environment. Utility Model Content

[0046] The utility model proposes an automatic filter element cleaning device, which realizes efficient cleaning of the filter element by utilizing high-pressure airflow and high-frequency vibration, and does not require manual participation, thus saving labor costs.
[0047] The cleaning device of the present application is described in detail through the following embodiments.
[0048] Example 1:
[0049] like Figure 1-Figure 3 As shown, in this embodiment, an automatic filter element cleaning device includes:
[0050] The dust removal box 100 has a chamber for placing the filter element 10 therein, and a door 110 is provided on the dust removal box 100 to cover the chamber;
[0051] The air supply assembly 200 is used to blow air into the filter element 10 in the chamber;
[0052] and a vibration assembly 300 for vibrating the filter element 10 in the chamber.
[0053] It is very convenient to place the filter element in the dust removal box 100 or to take the filter element out of the dust removal box 100 by opening the door 110. By arranging the air supply assembly 200 and the vibration assembly 300, the filter element can be cleaned efficiently by working together.
[0054] It should be noted that a placement rack 120 for placing the filter element is provided in the chamber, and the vibration assembly 300 is used to drive the placement rack 120 to vibrate at a high frequency.
[0055] Specifically, the vibration assembly 300 includes: an elastic member 310 , through which the bottom of the placement rack 120 is connected to the chamber; and a vibration motor 320 , which is disposed on the placement rack 120 .
[0056] Among them, the elastic member 310 is a spring, the bottom of which is fixed vertically to the bottom of the chamber through the base, and then the top of the spring is connected to the bottom of the placement rack 120. After such a design, the placement rack 120 can vibrate up and down, and under the action of the vibration motor 320, high-frequency vibration is achieved. Through high-frequency vibration, the dust in the filter element on the placement rack 120 is vibrated into the chamber.
[0057] It should be noted that the air supply assembly 200 includes: a bus 210; a plurality of air nozzles 220 disposed on the bus 210; and a sliding portion 230 for driving the bus 210 to move above the filter element placed in the chamber;
[0058] The ports of the air nozzles 220 face toward the filter element placed in the chamber.
[0059] Since the filter element is a rectangular parallelepiped, a busbar 210, multiple air nozzles 220, and a sliding portion 230 are provided to allow high-pressure gas to act on the entire filter element. Busbar 210 is a structure that can achieve both converging and diverting flow. It is a rectangular parallelepiped structure with a converging chamber inside. Several outlets connected to the converging chamber are located below or to the side of busbar 210. Several air nozzles 220 are located at each outlet. Busbar 210 also has an inlet connected to an external air pump (not shown) via an air pipe. Gas generated by the air pump enters busbar 210, is diverted, and then discharged from each outlet. Finally, the gas nozzles 220 act on the filter element, flushing one end of the filter element. The sliding portion 230 then slides busbar 210, allowing other locations on the filter element to be flushed. The repeated sliding of busbar 210 achieves comprehensive cleaning of the filter element.
[0060] Specifically, the sliding portion 230 includes a rodless cylinder disposed in the chamber; wherein the busbar 210 is disposed on the rodless cylinder.
[0061] Busbar 210 is installed within dust removal housing 100 via guide rails, and is linearly driven by a rodless cylinder. A rodless cylinder is a cylinder without a piston rod. It is connected directly or indirectly to an actuator via a piston, causing it to reciprocate with the piston. This design eliminates the presence of a protruding rod in a traditional cylinder, resulting in more uniform stress distribution and achieving higher precision, a shorter operating stroke, and smoother operation.
[0062] Example 2:
[0063] This embodiment is a further improvement based on the first embodiment.
[0064] like Figure 2 and Figure 3 As shown, in this embodiment, the placement rack 120 includes: a lower base plate 121; two side plates 122, which are respectively provided on both sides of the lower base plate 121; and two upper baffles 123, which are respectively provided on the two side plates 122;
[0065] The chamber enclosed by the lower base plate 121, the two side plates 122 and the two upper baffles 123 forms a placement chamber 124 for placing the filter element;
[0066] A flow strip 125 is further provided on the lower base plate 121 .
[0067] The filter element is placed in a chamber enclosed by the lower base plate 121, the two side plates 122 and the two upper baffles 123, and the structure is simple and practical.
[0068] The smooth rail 125, also known as the aluminum alloy slide rail 240, is a mechanical transmission component widely used in industrial automation and warehouse logistics. It is named for its quick and easy installation and the smooth movement of items placed on it. The smooth rail 125, installed on the lower base plate 121, facilitates the insertion and removal of filter cartridges into and from the placement cavity 124.
[0069] Example 3:
[0070] This embodiment is a further improvement based on any of the above embodiments.
[0071] like Figure 1 and Figure 2 As shown, in this embodiment, a funnel-shaped discharge port 126 is formed at the bottom of the chamber, and an opening 127 communicating with the discharge port 126 is formed on the lower bottom plate 121 .
[0072] The exhaust port 126 is provided to collect the fallen dust in a centralized manner.
[0073] Example 4:
[0074] This embodiment is a further improvement based on any of the above embodiments.
[0075] like Figure 1 As shown, in this embodiment, an observation window 130 is further provided on the top of the dust removal box 100 .
[0076] The observation window 130 is made of a transparent material to facilitate the staff to check the cleanliness of the filter element in the dust removal box 100.
[0077] Embodiment 5:
[0078] This embodiment is a further improvement based on any of the above embodiments.
[0079] like Figure 1 As shown, in this embodiment, rollers 140 are further provided around the bottom of the dust removal box 100 .
[0080] The rollers 140 are provided to facilitate movement of the entire cleaning device.
