Abstract
Description
Technical Field
[0001] This utility model relates to the field of wind turbines, and in particular to a novel volute. Background Technology
[0002] Currently, due to various reasons such as structure and operating conditions, it is difficult to ensure the uniformity of flow in the flow cavity of most fans. Problems such as flow separation, inter-blade vortex and backflow caused by uneven flow are all included. This has a significant impact on the fan's outlet noise, causing significant noise pollution and making the air duct connected to the volute prone to blockage. Therefore, a new type of volute is proposed. Utility Model Content
[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.
[0004] A novel volute includes a volute body and a fan installed inside the volute body. The volute body has an air duct formed therein, which surrounds the interior of the volute body and is connected to the fan via a pipeline. One end of the pipeline on the outer side of the volute body is provided with an air duct, which is interconnected with the air duct. The air duct and the air duct cooperate to allow airflow to circulate inside the volute body. A mesh cover is fitted on one side of the air duct, and a first partition and a second partition are respectively inserted inside the mesh cover. The first partition and the second partition are parallel to each other and are inserted through the air duct. A second mesh is provided in the middle of the first partition, and the second mesh and the first partition are on the same vertical plane and parallel to each other. A first mesh is provided in the middle of the second partition, and the first mesh and the second partition are on the same vertical plane and parallel to each other.
[0005] Preferably, the first partition is provided with a second insert plate protrusion, and the second insert plate protrusion is located on one side of the first partition, and the first partition and the second insert plate protrusion are in the same direction of movement.
[0006] Preferably, the second partition is provided with a first insert plate protrusion, and the first insert plate protrusion is located on one side of the second partition, and the second partition and the first insert plate protrusion are in the same direction of movement.
[0007] Preferably, a first through hole is provided between the air duct and the first partition, and the first through hole is formed on the side of the outside of the air duct, and the first partition passes through the first through hole.
[0008] Preferably, a second through hole is provided between the air duct and the second partition, and the second through hole is formed on the other side of the outside of the air duct, and the second partition passes through the second through hole.
[0009] Preferably, the duct is provided with an opening, and a mesh cover is provided between the opening and the duct. The mesh cover covers the air inlet and outlet of the duct, and the opening is covered outside the mesh cover, and the mesh cover and the opening are interconnected.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: when the first partition and the second partition are inserted into the air duct in sequence, the first screen and the second screen are respectively vertically located inside the air duct. Thus, through the double-layer dust isolation of the first screen and the second screen, the airflow blown out of the air duct or the airflow drawn from the outside by the fan is isolated from dust, preventing dust particles from clogging the air duct or air passage, thereby affecting the normal use of the fan. In addition, the first screen and the second screen can be pulled out from the air duct through the first partition and the second partition respectively for cleaning and can be reused.
[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-6 In this embodiment of the present invention, a novel volute includes a volute body 1 and a fan (not shown in the figure) installed inside the volute body 1. The volute body 1 is formed with an air duct 4, which surrounds the interior of the volute body 1 and is connected to the fan via a pipeline. One end of the pipeline on the outer side of the volute body 1 is provided with an air duct 2, and the air duct 2 and the air duct 4 are interconnected. The air duct 4 and the air duct 2 cooperate to allow airflow to circulate inside the volute body 1. A mesh cover 11 is fitted on one side of the air duct 2, and a first partition 6 and a second partition 7 are respectively inserted inside the mesh cover 11. The first partition 6 and the second partition 7 are parallel to each other and are respectively inserted through the air duct 2. A second mesh 10 is provided in the middle of the first partition 6. The first partition 6 and the second partition 7 are on the same vertical plane, and the second mesh 10 and the second partition 7 are parallel to each other. The first mesh 8 is provided in the middle of the second partition 7, and the first mesh 8 and the second partition 7 are on the same vertical plane and parallel to each other. When the first partition 6 and the second partition 7 are inserted into the air duct 2 in sequence, the first mesh 8 and the second mesh 10 are respectively vertically located inside the air duct 2. Thus, through the double dust isolation of the first mesh 8 and the second mesh 10, the airflow blown out by the fan through the air duct 2 or the airflow drawn from the outside is isolated from dust, preventing dust particles from clogging the air duct 2 or the air passage 4, thereby affecting the normal use of the fan. The first mesh 8 and the second mesh 10 can be pulled out from the air duct 2 through the first partition 6 and the second partition 7 respectively for cleaning and can be reused.
[0022] The first partition 6 is provided with a second insert plate protrusion 9, and the second insert plate protrusion 9 is located on one side of the first partition 6. The first partition 6 and the second insert plate protrusion 9 are in the same direction of movement, so that when the first partition 6 is inserted into the air duct 2, the two ends of the second insert plate protrusion 9 abut against the outer side of the air duct 2. This prevents the first partition 6 from being completely inserted into the air duct 2 and allows the first partition 6 to be pulled out of the air duct 2 along with the second insert plate protrusion 9.
[0023] The second partition 7 is provided with a first insert plate protrusion 5, and the first insert plate protrusion 5 is located on one side of the second partition 7. The second partition 7 and the first insert plate protrusion 5 are in the same direction of movement, so that when the second partition 7 is inserted into the air duct 2, the two ends of the first insert plate protrusion 5 abut against the outer side of the air duct 2, thereby preventing the second partition 7 from being completely inserted into the air duct 2 and allowing the second partition 7 to be pulled out from the air duct 2 along with the first insert plate protrusion 5.
[0024] A first through hole (not shown in the figure) is provided between the air duct 2 and the first partition 6, and the first through hole is formed on the side of the air duct 2. The first partition 6 passes through the first through hole, so that the first partition 6 can be inserted into the air duct 2 through the first through hole.
[0025] A second through hole (not shown in the figure) is provided between the air duct 2 and the second partition 7, and the second through hole is formed on the other side of the outside of the air duct 2. The second partition 7 passes through the second through hole, so that the second partition 7 can be inserted into the air duct 2 through the second through hole.
[0026] The air duct 2 is provided with a pipe opening 3, and a mesh cover 11 is provided between the pipe opening 3 and the air duct 2. The mesh cover 11 covers the air inlet and outlet of the air duct 2, and the pipe opening 3 covers the outside of the mesh cover 11. The mesh cover 11 and the pipe opening 3 are interconnected, so that the airflow entering the volute body 1 is initially dust-proofed through the mesh cover 11.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
