Description

Technical Field

[0001] The utility model belongs to the technical field of external blowing rings, and particularly relates to a galvanized external blowing ring with adjustable pressure. Background Art

[0002] The external blowing ring is a commonly used device in industrial production. The external blowing ring uses compressed air or other gases (such as nitrogen) to eject high-speed airflows through small holes or slits on the annular structure, forming an air curtain covering the surface of the object. These airflows can effectively blow away impurities such as moisture and dust attached to the surface, achieving the effects of drying and cleaning. During the process of steel pipe galvanizing production, a blowing ring is usually used to quickly clean the galvanized steel pipe. The air outlet pressure and air outlet speed of the existing blowing ring are fixed and cannot be adjusted according to different production needs. Therefore, it cannot meet different production needs, has low practicability, and has certain limitations. Content of the Utility Model

[0003] In view of this, the utility model aims to provide a galvanized external blowing ring with adjustable pressure to solve the problem that the air outlet pressure and speed cannot be adjusted according to different production requirements, and thus cannot meet different production needs.

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0005] A galvanized external blowing ring with adjustable pressure.

[0006] Furthermore, it includes: a housing; the housing adopts an annular structure, and an annular cavity structure is provided inside the housing. The bottom of the housing is provided with a through-type circular groove structure in an annular array; an annular inner housing is fixedly arranged on the inner side of the housing. Six groups of through-type circular groove structures are provided in an annular array on the inner side of the inner housing, and six groups of rectangular groove structures are provided in an annular array on the inner side of the inner housing; six groups of cylindrical sliders are fixedly arranged in an annular array in the rectangular grooves on the inner wall of the inner housing; a sliding frame with a rectangular frame structure is slidably arranged on the outer side of the slider, and a through-type screw hole structure is provided at the top of one side of the sliding frame.

[0007] Furthermore, a group of air inlets are fixedly connected to the bottoms of the six groups of circular grooves at the bottom of the housing; a cylindrical fixed rod is fixedly arranged on one side inside the annular cavity of the housing; a circular extrusion plate is slidably arranged on the outer side of the fixed rod, and a through-type screw hole structure is provided at the top of one side of the extrusion plate. The outer wall of the extrusion plate is in contact with the inner wall of the housing.

[0008] Further, a first screw is rotatably provided on one side inside the annular cavity of the housing, and the first screw is connected to the extrusion plate through a threaded fit; a second screw is rotatably provided inside the rectangular groove on the inner wall of the inner housing, and the second screw is connected to the sliding frame through a threaded fit; a pressure hood is fixedly provided above the inner side of the sliding frame, and the pressure hood is a tapered cylinder structure that is wider at the rear and narrower at the front, and the rear wall of the pressure hood fits against the inner wall of the inner housing.

[0009] Further, a pressure reduction hood is fixedly provided at the bottom inside the sliding frame, and the pressure reduction hood is a tapered cylinder structure that is narrower at the rear and wider at the front, and the rear wall of the pressure reduction hood fits against the front wall of the inner housing.

[0010] Compared with the prior art, the galvanized external blowing ring with adjustable pressure of the present invention has the following beneficial effects:

[0011] In this application, by adjusting the position of the extrusion plate, the size of the inner cavity of the housing is adjusted. Thus, when the cavity becomes smaller, the smaller space can increase the outflow speed of the air flow, thereby further increasing the wind pressure and wind speed. At the same time, in cooperation, the pressure hood is slid to the front side of the circular through-hole of the inner housing. Through the tapered structure of the pressure hood, the air flow can be pressurized, so that the air flow blows out from the small holes on the front side of the pressure hood, thereby increasing the wind pressure.

[0012] When it is necessary to reduce the wind pressure and wind speed, the extrusion plate is retracted to the upper side of the housing cavity to increase the space inside the housing. At the same time, the second screw is rotated reversely to drive the sliding frame to slide upward along the slide rod, so that the pressure reduction hood moves to the front side of the inner housing. Through the pressure reduction hood, the outflow speed of the air flow can be effectively reduced, thereby reducing the wind speed and wind pressure, facilitating adjustment according to different usage requirements, greatly improving the practicability of the device, meeting different production needs, and the adjustment operation is simple and fast.

[0025] Among them, a group of air inlets 101 are fixedly connected to the bottoms of the six groups of circular through-holes at the bottom of the housing 1; a cylindrical fixed rod 103 is fixedly arranged on one side inside the annular cavity of the housing 1; a circular extrusion plate 104 is slidably arranged on the outer side of the fixed rod 103, and a through screw hole structure is provided at the top of one side of the extrusion plate 104, and the outer wall of the extrusion plate 104 is attached to the inner wall of the housing 1.

[0026] Wherein, a first screw rod 105 is rotatably arranged on one side inside the annular cavity of the housing 1, and the first screw rod 105 is connected with the extrusion plate 104 through threaded fit; a second screw rod 107 is rotatably arranged inside the rectangular groove on the inner wall of the inner housing 102, and the second screw rod 107 is connected with the sliding frame 108 through threaded fit; a pressure hood 109 is fixedly arranged above the inner side of the sliding frame 108, and the pressure hood 109 adopts a conical cylinder structure that is wider at the back and narrower at the front, and the rear wall of the pressure hood 109 fits against the inner wall of the inner housing 102.

[0027] Specific usage method and function of this embodiment:

[0028] During use, wind force is introduced into the cavity inside the housing 1 through the air inlet 101, and then blown out through the circular through-hole on the inner housing 102, so as to blow the surface of the galvanized steel pipe. If the wind pressure needs to be adjusted, the second screw rod 107 can be rotated to drive the sliding frame 108 to slide downward along the sliding rod 106, so that the pressure hood 109 slides to the front side of the circular through-hole of the inner housing 102. Through the conical structure of the pressure hood 109, the air flow can be pressurized, so that the air flow blows out from the small holes on the front side of the pressure hood 109, thereby increasing the wind pressure, and further achieving the purpose of increasing the air flow pressure.
