Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
Examples: at present, the cleaning mode of an air inlet filter screen of a fan is mature, but the electric devices such as a motor are usually used for cleaning (such as a brush is driven by the motor to frequently clean the screen surface and the like); when the filter screen is blocked and is in a working state of the fan, the cleaning process actually has certain difficulty, for example, when the machine is stopped for cleaning, the working of the fan can be influenced; when cleaning is not stopped, dust can rise near the filter screen and cover the filter screen again along with the introduction of air flow (namely blockage always exists), and for this purpose, I make the following improvements.
Referring to fig. 1 to 11, the present invention provides a parallel centrifugal fan, which includes a fan body 1, an air inlet pipe 101 communicating with an inlet of the fan body 1, wherein the length of the air inlet pipe 101 is only shown in the figure, and different lengths can be set for practical use, and air inlets are arranged at the upper part of one side of the air inlet pipe 101; also comprises an annular frame 2, a filter ball 201, an annular brush plate 203 and a rotating plate 204;
The annular frame 2 is arranged in the air inlet pipe 101, and the outer annular surface of the annular frame 2 is attached to the inner wall of the air inlet pipe 101; the whole filter ball 201 is spherical, and is specifically formed by a spherical framework and a filter screen wrapped outside the spherical framework, wherein the spherical framework is used for supporting the filter screen, the mesh number of the filter screen can be set according to the requirement, and dust and impurities are reduced from entering the fan body 1 mainly by the aid of the filter screen; the filter ball 201 is rotatably arranged in the annular frame 2 through the rotating rod 202, and the side surface of the filter ball 201 is always attached to the inner annular surface of the annular frame 2, so that the separation of dust and impurities in the air can be realized only through the surface filter holes of the filter ball 201; the annular brush plate 203 is concentrically arranged with the annular frame 2, and is rotatably arranged on one side of the annular frame 2 adjacent to the air inlet of the air inlet pipe 101, and the edge of one side of the annular brush plate 203 far away from the annular frame 2 is always attached to the surface of the filter ball 201; the edge of one side of the annular brush plate 203 far away from the annular frame 2 is also radially and circumferentially provided with a plurality of bristles (not shown) attached to the surface of the filter ball 201;
By the arrangement of the filtering balls 201, as shown in fig. 2, on one hand, the spherical convex surface of the filtering balls 201 between the annular frame 2 and the inlet of the air inlet pipe 101 can increase the area for filtering air, so as to ensure the filtering effect of dust and impurities in the air and the speed of the air entering the fan body 1 (compared with the existing plane filter screen, the number of the filtering holes is increased); on the other hand, as shown in fig. 2 and 6, dust and impurities filtered by the filter ball 201 will move along the arc surface of the filter ball 201 towards the direction of the annular brush plate 203 and temporarily store at the junction of the annular brush plate 203 and the filter ball 201, so that the cleanness of the rest surfaces of the filter ball 201 is ensured by temporarily storing, and the efficiency of introducing air from the air inlet pipe 101 into the fan body 1 is improved.
As shown in fig. 3, the rotating plate 204 is integrally located inside the filter ball 201, and the rotating plate 204 is provided with a plurality of rotating plates and is circumferentially and equidistantly distributed on the side surface of the rotating rod 202, because the rotating plate 204 is located inside the air inlet pipe 101, the rotating plate 204, the rotating rod 202 and the filter ball 201 are driven to rotate anticlockwise by the flow of the air along with the continuous introduction of the air flow from the air inlet at the upper part of the air inlet pipe 101, and it is worth noting that the rotating speed of the rotating rod 202 can be controlled by damping, and the rotating speed of the rotating rod 202, that is, the rotating speed of the filter ball 201, can be adjusted according to actual needs, which is a known technology and will not be repeated.
When in operation, the device comprises: referring to fig. 1,2 and 4, firstly, the fan body 1 acts to suck external air through the air inlet pipe 101, and the air flow is filtered through the filtering balls 201 in advance, so that the air filtering effect is achieved, dust and impurities are reduced from entering the fan body 1, and the service life of internal components of the fan body 1 is prolonged;
Secondly, the spherical convex surface of the filter ball 201 between the annular frame 2 and the inlet of the air inlet pipe 101 can increase the area of the filter ball 201 for filtering air, and ensure the filtering effect of dust and impurities in the air and the speed of the air entering the fan body 1; the dust and impurities filtered by the filter ball 201 can move along the arc-shaped surface of the filter ball 201 and are temporarily stored at the junction of the annular brush plate 203 and the filter ball 201, so that the cleanness of the other surfaces of the filter ball 201 is ensured in a temporary storage mode, and the efficiency of introducing air from the air inlet pipe 101 into the fan body 1 is improved;
Meanwhile, as shown in fig. 3 and 6, air continuously enters and pushes the rotating plate 204 to rotate, the rotating plate 204 drives the rotating rod 202 and the filter ball 201 to rotate, and as the annular frame 2 and the annular brush plate 203 are attached to the surface of the filter ball 201, the annular brush plate 203 can wipe the surface of the filter ball 201 in the rotating process, so that dust impurities with strong adhesiveness (such as particles, dust, greasy dirt, fibers and the like trapped by the filter ball 201 and left on the surface of the filter ball 201) are cleaned, the cleaned dust impurities temporarily exist at the junction of the filter ball 201 and the annular brush plate 203, so that the other surfaces of the filter ball 201 except the junction are relatively clean, and the efficiency of the filter ball 201 on air filtration and the air inflow are further improved;
In summary, due to the cooperation of the filter ball 201, the rotating plate 204 and the annular brush plate 203, when the fan body 1 acts, dust impurities in air can be automatically filtered, and the surface of the filter ball 201 can be automatically cleaned, so that the dust impurities can only temporarily exist in a designated interval (near the junction of the filter ball 201 and the annular brush plate 203), the cleanness of the rest surfaces of the filter ball 201 is ensured, the air filtering efficiency and the air inlet amount are ensured through the clean surfaces of the filter ball 201, the frequency of shutdown cleaning is reduced, and the operation and maintenance cost is reduced.
Referring to fig. 2, 5 and 6, in order to further improve the cleanliness of the surface of the filter ball 201; for this purpose, the outer ring surface of the annular brush plate 203 is also sleeved with a gear ring 3; the air inlet pipe 101 is provided with a gear 301 meshed with the gear ring 3 through a shaft lever; the adjacent ends of the rotating rod 202 and the shaft rod extend to the outside of the air inlet pipe 101, and the extending ends of the rotating rod 202 and the shaft rod are connected through a belt pulley assembly (shown in the figure but not numbered);
