The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses an go up dust exhausting formula prefilter, prefilter and air cleaner cooperation for carry out prefiltering to the air and handle, mainly be used for separating great impurity in the air. This prefilter improves the filter effect to the impurity dust through setting up centrifugal rotating fan.
As shown in fig. 1 and 2, the prefilter includes an upper housing 1 and a lower housing 4 fixed to a lower end of the upper housing 1. The upper cover body 1 and the lower seat body 4 are combined and connected together to form a shell of the prefilter. The upper cover body 1 is closed at the upper end and opened at the lower end of the upper cover body 1. The upper shell 1 is preferably provided with a cylindrical shape. In a specific implementation, the upper cover 1 and the lower seat 4 are butted together and then fastened together using fastening bolts.
The prefilter takes in air from the lower end and discharges dust and impurities from the upper part of the upper cover 1. The lower seat body 4 is provided with an air inlet and an air outlet, and as shown in fig. 2, the lower seat body 4 comprises an air outlet 2 positioned at the central position and a plurality of air inlet ducts 3 arranged around the air outlet 2. The main improvement of the prefilter is that several air inlet ducts 3 are arranged in a distributed manner in a helical turbine structure. The section of the air inlet duct 3 from the air inlet end to the air outlet end gradually increases and tends to rise. The distribution structure and the cross-sectional structure of the air inlet duct 3 are matched, so that air can form spiral airflow after passing through the air inlet duct, and centrifugal force is generated. The air outlet 2 is of a cylindrical structure, the upper end of the air outlet 2 is positioned in the upper cover body 1, and the lower end of the air outlet 2 extends to the position below the lower end face of the upper cover body 1; the filtered air flows downward from the upper end of the air outlet 2 in the upper cover 1 and is discharged outward through the lower end of the air outlet 2. After the prefilter is installed, the lower end of the air outlet 2 is communicated with an air inlet of an air filter.
At least one waste discharge opening 6 is formed in the side wall of the upper cover body 1, and dust impurities are centrifugally thrown to the side wall of the upper cover body 1 and then discharged from the waste discharge opening 6. As shown in figure 1, the waste discharge opening 6 is formed by inward recovery of one section of the upper part of the side wall of the upper cover body 1, and the waste discharge opening 6 of the structure is beneficial to the outward discharge of dust impurities. Because the dust impurities move along the side wall of the upper cover body 1 under the centrifugal action, one of the side walls of the upper cover body 1 is bent inwards to be recovered, and the dust impurities passing through the side wall can be discharged outwards.
As shown in fig. 2, a centrifugal rotary fan is correspondingly disposed at the upper end of the air outlet 2, and the centrifugal rotary fan is used for promoting the centrifugal rotation of the air and pushing the dust impurities in the air in an outward direction. The centrifugal rotating fan is powered by the spiral air flow formed through the air inlet duct 3. The spiral air flow can drive the centrifugal rotating fan to rotate without additional power. The centrifugal rotary fan is suspended above the inside of the upper cover 1 by a bearing 5.
The centrifugal rotary fan is specifically configured to include a rotary shaft 7, a coupling piece 8, and fan blades 9. Wherein, one end of the connecting sheet 8 is fixedly connected with the rotating shaft 7, and the other end is fixedly connected with the fan blade 9. The centrifugal rotary fan is formed by fixedly connecting 3-4 groups of connecting pieces 8 and fan blades 9 on a rotating shaft 7. The upper end of the rotating shaft 7 is fixedly connected with the bearing 5, and the bearing 5 is inserted into the bearing seat 10. The bearing seat 10 is mounted on the upper end surface of the upper cover 1. Here, the bearing 5 is generally a radial ball bearing, an outer ring of which is mounted in the bearing seat 10 by interference fit, and then an upper end of the rotary shaft 7 is also mounted in an inner ring of the radial ball bearing by interference fit.
The centrifugal rotary fan is further improved by arranging the connecting piece 8 in an arc structure along the length direction, and making the opening of the arc structure be the reverse direction of the spiral turbine structure formed towards the air inlet duct 3. As shown in particular in fig. 2. The structure accords with the principle of air flow, can ensure that the separation effect and the resistance of the prefilter reach better balance level, and has good separation effect and high filter precision.
In a specific implementation, the bearing seat 10 includes a clamping seat clamped on the upper end surface of the upper cover body 1 and a bearing insert barrel integrally arranged on the lower end surface of the clamping seat. The bearing cartridge penetrates through the upper end face of the upper cover body 1, and the bearing cartridge extends downwards into the upper cover body 1, so that the bearing 5 can be inserted into the bearing cartridge. The clamping seat part of the bearing seat 10 is positioned outside the upper cover body, and the bearing insert cylinder is positioned inside the upper cover body. The bearing seat 10 and the bearing 5 are matched, so that the suspension arrangement of the centrifugal rotating fan is realized, and the smooth rotation of the centrifugal rotating fan can be ensured.
When the device works, air enters from the air inlet duct below under the action of the suction force of the engine, a spiral airflow can be formed under the action of the air inlet duct of the spiral turbine mechanism, impurities are centrifugally separated from the upper part of the upper cover body, and air purification is carried out; the purified air moves from the upper end to the lower end of the air outlet and is discharged from the lower end of the air outlet.
The upper cover body 1, the lower seat body 4, the air outlet 2, the centrifugal rotating fan and other auxiliary components of the prefilter are preferably made of modified reinforced nylon materials, and the prefilter has the characteristics of compact structure, light overall weight, and durability for a long time.
The utility model relates to an go up dust exhausting formula prefilter through setting to the wind channel that admits air of spiral turbine structure distribution, can make the air form the spiral air current to produce the dust impurity centrifugal separation of centrifugal action power in with the air. Meanwhile, the centrifugal rotating fan is arranged and is driven by the spiral airflow to rotate, so that the further centrifugal acting force on the dust and impurities is exerted, and the effect of centrifugally separating the impurities is improved. The pre-filter has a good pre-filtering effect on air.
