Description

Technical Field

[0001] The utility model relates to the technical field of wind ring structures, in particular to an integrated wind ring that is convenient for installing a paper frame filter and a static pressure box. Background Art

[0002] With the development of industrial technology, wind ring structures have been widely used in many fields, such as air purification and ventilation systems. The wind ring is a key structural component. It is usually located inside the air inlet and has a bell-shaped inlet with an outward-flashing rim. This bell-shaped inlet is nestled within the rim of the impeller's air intake to ensure smoother airflow through the wind ring and into the impeller. The design of the wind ring ensures that all air drawn in by the wind ring enters the impeller, preventing air from escaping through the gap between the impeller's air intake and the bell-shaped inlet of the wind ring, thereby improving the efficiency of the fan.

[0003] However, the device and the prior art still have the following defects:

[0004] The existing integrated wind ring structure is round at the top and square at the bottom, and the wind ring air inlet surface is round. The square paper frame filter and static pressure box cannot be installed normally on the wind ring air inlet surface. The stability of the installed paper frame filter and static pressure box cannot be guaranteed. The vibration force generated during use can easily cause the installed paper frame filter and static pressure box to loosen, reducing the installation effect of the paper frame filter and static pressure box, and cannot meet the use requirements. Utility Model Content

[0005] The utility model aims to provide an integrated wind ring which is convenient for installing a paper frame filter and a static pressure box.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The filter housing of the invention is a filter housing, and the filter housing is a filter housing.

[0008] By adopting the above technical solution, the connecting holes on the paper frame filter and the static pressure box are aligned with the connecting rod. After the connecting rod is fully inserted, the compression spring applies thrust to the insert block. Under the action of the thrust, one end of the insert block is aligned with the limit groove and pushed in, thereby limiting the inserted connecting rod and improving the firmness of the connection between the paper frame filter, the static pressure box and the air ring.

[0009] Furthermore, a V-shaped reinforcement rib is provided on the outside of the wind ring body, and the V-shaped reinforcement rib is integrated with the wind ring body. The air inlet cover and the wind ring body are integrally die-cast in one step, and the air inlet surface of the air inlet cover is set to be square.

[0010] By adopting the above technical solution, the V-shaped reinforcement ribs increase the structural strength of the wind ring and can withstand a greater load. The air inlet surface is a square plane, which makes it easy to connect and fix the paper frame filter and the static pressure box to the wind ring.

[0011] Furthermore, a threaded hole is provided on the end face of the air inlet cover, and there are four threaded holes. A screw is provided at one end of each of the four connecting rods, and the screw and the connecting rod are integrated. The screw and the threaded hole are provided correspondingly, and the screw is threadedly connected to the air inlet cover.

[0012] By adopting the above technical solution, the screw is aligned with the threaded hole and screwed in to connect the connecting rod to the air inlet cover. The connecting rod is installed when the paper frame filter and the static pressure box are installed, and the connecting rod is removed when the paper frame filter and the static pressure box are not installed.

[0013] Furthermore, a sealing gasket is provided on the end surface of the air inlet cover, and the sealing gasket is fitted and connected to the air inlet cover.

[0014] By adopting the above technical solution, the sealing gasket fills the gap between the paper frame filter, the static pressure box and the air inlet hood, thereby improving the sealing performance of the connection between the paper frame filter, the static pressure box and the air inlet hood.

[0015] Furthermore, the cross-sections of the insert block and the limiting groove are both arranged in a right-angled trapezoidal shape.

[0016] Furthermore, pull rods are provided on both sides of the paper frame filter and the static pressure box, and the pull rods are provided corresponding to the connection holes. One end of the pull rod is fixedly connected to the plug block, and the pull rod is slidably connected to the compression spring.

[0017] By adopting the above technical solution, the pull rod guides and limits the telescopic plug-in block. When disassembling the paper frame filter and the static pressure box, the plug-in block is pulled out of the limiting groove and separated from the connecting rod by the pull rod, and the connecting rod is pulled out of the connecting hole to complete the disassembly of the paper frame filter and the static pressure box.

[0018] Furthermore, an elastic washer is provided at the bottom of the connection hole, and the elastic washer is fixedly connected to the paper frame filter.

[0019] By adopting the above technical solution, the connecting rod is fully inserted into the connecting hole to squeeze the elastic gasket, and the squeezed elastic gasket applies thrust to the connecting rod, so that the insert is in close contact with the connecting rod, thereby improving the installation stability of the paper frame filter and the static pressure box.

[0020] In summary, the beneficial technical effects of the present invention are:

[0021] 1. The system uses a connecting rod, a connecting hole, an insert, a compression spring, and a limit slot. The connecting rod is aligned with the connecting hole and inserted to connect the paper frame filter or static pressure box to the wind ring. After the connecting rod is fully inserted, the compression spring applies a thrust to the insert. Under the action of the thrust, one end of the insert is aligned with the limit slot and pushed in, limiting the inserted connecting rod and improving the firmness of the connection between the paper frame filter and static pressure box and the wind ring.

[0022] 2. Sealing pads and elastic washers are used. The sealing pads fill the gaps between the paper frame filter, static pressure box and air inlet cover, improving the sealing performance of the connection between the paper frame filter, static pressure box and air inlet cover. The connecting rod is fully inserted into the connecting hole to squeeze the elastic washers. The squeezed elastic washers apply thrust to the connecting rod, making the inserts in close contact with the connecting rod, thus improving the installation stability of the paper frame filter and static pressure box.

[0023] 3. A pull rod is used to guide and limit the telescopic plug-in. When disassembling the paper frame filter and the static pressure box, the plug-in is pulled out of the limit slot and separated from the connecting rod by the pull rod, and the connecting rod is pulled out of the connecting hole to complete the disassembly of the paper frame filter and the static pressure box.
