Abstract
The application discloses a fan with a replaceable lining plate, which belongs to the field of fans and is used for fans, and the fan comprises side plates which are arranged in parallel, wherein a volute plate fixedly connected with the side plates is arranged between the side plates, two ends of the volute plate are provided with connecting plates which are vertically and fixedly connected with the volute plate, and the connecting plates are in surface contact with the side plates on the corresponding side and are detachably connected with the side plates; the inner side surface of the volute plate is covered with a lining plate. In view of above-mentioned technical scheme, this application can increase the convertibility of fan volute shell board, improves the life of fan, reduces the subsequent maintenance cost of fan.
Description
Technical Field
This application belongs to the fan field, and specifically speaking especially relates to a fan of removable welt.
Background
When the common fan is applied to the condition that the dust content of gas is higher or the common fan is used for conveying solid particle media, the abrasion degree of the volute plate part in the fan is higher, and the service life of the fan is influenced. And in case the volute casing board in current fan structure is worn and torn, it needs wholly to be changed, not only influences life, causes the increase of change maintenance cost moreover.
Disclosure of Invention
An object of this application is to provide a fan of removable welt, its replaceability that can increase fan volute casing board improves the life of fan, reduces the subsequent maintenance cost of fan.
In order to achieve the purpose, the method is realized by the following technical scheme:
the fan with the replaceable lining plate comprises side plates which are arranged in parallel, a volute plate fixedly connected with the side plates is arranged between the side plates, connecting plates vertically and fixedly connected with the two ends of the volute plate are arranged at the two ends of the volute plate, and the connecting plates are in surface contact with the side plates on the corresponding side and are detachably connected with the side plates; the inner side surface of the volute plate is covered with a lining plate.
Further, the detachable connection mode in this application is for adopting connecting bolt to connect curb plate and connecting plate.
Further, the lining plate is fixedly connected with the connecting plates on the two sides in a welding mode.
Compared with the prior art, the beneficial effects of this application are:
this application is through regarding welt and spiral case board as overall structure to carry out detachable with the curb plate through the connecting plate of both sides and be connected, the replaceability of the position of wearing and tearing in the fan effectively improves, helps reducing after-sale maintenance's cost, increases the life of fan.

In the figure: 1. a side plate; 2. a connecting plate; 3. a volute plate; 4. a connecting bolt; 5. a liner plate.
Detailed Description
The technical solutions described in the present application are further described below with reference to the accompanying drawings and embodiments. It should be noted that the following paragraphs may refer to terms of orientation including, but not limited to, "upper, lower, left, right, front, rear", etc., which are based on the orientation shown in the drawings corresponding to the specification, and should not be construed as limiting the scope or technical solutions of the present application, but merely as facilitating better understanding of the technical solutions described in the present application by those skilled in the art.
Example 1: as shown in fig. 1 to 3, a fan with replaceable lining plate at least comprises a side plate 1 and a volute plate 3 which form a centrifugal fan casing, wherein the side plate 1 is distributed at two ends of the volute plate 3, a lining plate 5 covers the inner side surface of the volute plate 3, two ends of the lining plate 5 are connected with a connecting plate 2 after being attached to the volute plate 3, the connecting plate 2 is parallel and attached to the inner side of the side plate 1, and through holes for connecting bolts 4 to pass through are processed at corresponding positions on the connecting plate 2 and the side plate 1.
On the basis of the above-mentioned embodiments, the present application continues to describe the technical features and functions of the technical features mentioned therein in detail to help those skilled in the art to fully understand the technical solutions of the present application and reproduce the same.
In the application, the two sides of the volute plate 3 are provided with the side plates 1 perpendicular to the volute plate, the adjacent side plates 1 are arranged in parallel, and the volute plate 3 and the side plates form a centrifugal fan shell together. As shown in fig. 2 to 3, the two ends of the volute plate 3 are welded with the side plates 1 perpendicular to the side plates and parallel to the side plates 1, and the side plates 1 and the connecting plate 2 are attached to each other and detachably fixed by the through holes at the corresponding positions in the form of the connecting bolts 4.
In the application, the volute casing plate 3 is attached to and covered with a lining plate 5 on the surface inside the fan casing. The lining plate 5 is made of wear-resistant materials, the wear-resistant performance of the volute plate 3 can be improved on the windward side, the lining plate 5 and the volute plate 3 are replaced by disassembling the connecting bolt 4 when the normal use of the fan is influenced, and the use of other parts is not influenced.
