Description

Collector convenient to clearance

Technical Field

The utility model relates to a fan collector technical field, concrete field is a collector convenient to clearance.

Background

The collector is an important auxiliary part of the axial flow fan and forms a tapered flow passage together with the streamline cover, so that airflow is accelerated, and a uniform speed field and a uniform pressure field are established in front of an inlet of the fan, so that the flow loss is reduced, and the efficiency of the fan is improved. The gas flow velocity in the current collector is not large, the tube length is short, the flow loss is not large, and the uniform flow field of the inlet condition can be met and the efficiency can be ensured under the general condition. Collector form can influence fan performance, and the collector flow loss that designs well is less, and unreasonable design can make the import condition worsen, leads to the performance reduction.

Axial flow fan collectors are most commonly used in three forms: cylindrical, conical, and circular arc.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-2, the present invention provides a technical solution: a current collector convenient to clean comprises a current collector shell 1, wherein the current collector shell 1 is a revolving body, a conical or arc current collector can be selected according to actual conditions, the current collector shell 1 is a revolving body which has good current collecting performance on one hand, and on the other hand, a cleaning device is conveniently arranged in the revolving body, so that the cleaning device rotates around the axis of the revolving body, and the cleaning of the inner wall of the current collector shell 1 can be completed, an annular chute 2 is arranged on the outer side wall of an air inlet of the current collector shell 1, an annular sliding block 4 is connected to the outer surface of the annular chute 2 in a sliding manner, a rotary disc 5 is fixedly connected to the surface of one side, far away from the air outlet of the current collector shell 1, of the annular sliding block 4, the rotary disc 5 is annular, namely the rotary disc 5 can rotate around the axis of the current collector, therefore, the rotating disc 5 is arranged at the air inlet end of the current collector housing 1, since the air inlet end of the current collector housing 1 may also need to be placed with some specific devices, such as an adjusting baffle, etc., and the rotating disc 5 is a circular ring and arranged at the end face of the current collector housing 1, which does not hinder the installation of the devices and does not occupy too much space, the inner surface of the rotating disc 5 is provided with a cross bar 6, the cross bar 6 is located inside the current collector housing 1, and the length of the cross bar 6 is the same as that of the current collector housing 1, so that the cross bar 6 can cover the entire inner surface of the current collector housing 1 when rotating, thereby realizing complete cleaning, and it should be noted that, since the current collector housing 1 is an irregular solid structure, the inner surface of the current collector housing 1 is also an irregular surface, and the cross bar 6 needs to determine its shape according to the inner surface of the current collector housing 1, that is, the vertical distances between each position of the cross bar 6 and the inner surface of the current collector shell 1 corresponding to the cross bar are the same, and the surface of one side of the cross bar 6, which is far away from the axis of the current collector shell 1, is provided with the cleaning brush 7, so that the cleaning brush 7 can be perfectly attached to the inner surface of the current collector shell 1, and the current collector can be cleaned more thoroughly.

Specifically, the cleaning brush 7 contacts with the inner surface of the current collector housing 1, and when the rotating disc 5 rotates, the cross bar 6 is driven to rotate inside the current collector housing 1, and the cleaning brush 7 contacts with the inner surface of the current collector housing 1, so that the cleaning brush 7 can clean the inner surface of the current collector housing 1 comprehensively.

Specifically, a dust collecting groove 11 is formed in one side surface of the cross rod 6, the dust collecting groove 11 is communicated with the current collector shell 1, the rotary disc 5 needs to rotate to the side, where the dust collecting groove 11 is formed in the cross rod 6, of the cross rod, and due to the fact that the dust collecting groove 11 is communicated with the current collector shell 1, dust brushed down can enter the dust collecting groove 11 temporarily, and cannot fall from the inner surface of the current collector shell 1 to enter a fan.

In particular, the collector housing 1 is curved to prevent a vortex region from being formed at the inlet of the impeller, so that the effect is better when air is directly introduced from the atmosphere.

The working principle is as follows: the utility model discloses when needs are cleared up, only need to rotate carousel 5, because of

carousel

5 and 4 fixed connection of annular slider, and 2 sliding connection of annular slider 4 and annular spout to make carousel 5 can surround the axle center rotation of collector casing 1, after rotatory, carousel 5 drives horizontal pole 6 and rotates in collector casing 1's inside, and fix the cleaning brush on horizontal pole 6 and can clear up adnexed dust on collector casing 1's the internal surface.

Example 2

Referring to fig. 3-4, the difference between the present embodiment and embodiment 1 is: the lateral wall of carousel 5 is equipped with through-hole 8, the inside wall sliding connection of through-hole 8 has pull rod 9, pull rod 9 can the inside of through-hole 8 slides, pull rod 9 is located the inboard one end fixedly connected with of carousel 5 horizontal pole 6, the internal surface of current collector casing 1 is equipped with accomodates groove 10, horizontal pole 6 is located accomodate the inside of groove 10, through promoting pull rod 9 makes horizontal pole 6 is followed stretch out in accomodating the groove 10, and after the clearance is accomplished, will horizontal pole 6 rotates accomodate groove 10 department, pulling pull rod 9 makes horizontal pole 6 gets into accomodate in the groove 10, thereby make the only whole in the inside of current collector casing 1 can not be because of horizontal pole 6 destroys its inside air flow.

Example 3

Referring to fig. 5-6, the difference between the present embodiment and embodiment 2 is: specifically, the accommodating grooves 10 are through grooves, and after the cross bars 6 rotate around the inside of the collector housing 1 for one circle, the removed dust can be discharged out of the device through the accommodating grooves 10, and it should be noted that, because the accommodating grooves 10 are through grooves, after the cross bars 6 enter the inside of the accommodating grooves 10, the cross bars 6 should seal the accommodating grooves 10, so as to ensure the air tightness of the collector.

Specifically, a limiting plate 12 is disposed on the outer surface of the pull rod 9 and outside the rotating disc 5, and when the pull rod 9 is pushed, the limiting plate 12 contacts the rotating disc 5, and the cleaning brush 7 is just located on the inner surface of the current collector housing 1.

Particularly, the surface cover of pull rod 9 is equipped with spring 3, just spring 3 be located carousel 5 with between the limiting plate 12, spring 3 will pull rod 9 pushes away to the outside, thereby makes horizontal pole 6 produces the effort to the outside, and when the clearance, horizontal pole 6 drives cleaning brush 7 can tightly paste the internal surface of collector casing 1, and on the other hand is accomplishing clean back, horizontal pole 6 gets into receive behind the groove 10, can comparatively stable fixed.
