Description

Annular air knife for cleaning inner wall of material container barrel

Technical Field

The invention relates to water removal, dust removal and cleaning of planes or cylinders of industrial products, in particular to an annular air knife for cleaning the inner wall of a material container barrel, which removes dust and water in the interior of an industrial barrel.

Background

The air knife comprises a strip-shaped air knife and an annular air knife, and is a product which is specially designed for blowing out strong high-speed airflow to blow off dust, blow dry water stains and cool.

In the face of the problems of blowing dust and drying water stain on the inner wall of the barrel, the traditional modes such as a dryer are generally adopted at present. Traditional blowing application products have a number of drawbacks, such as: the blown air flow is not uniform; the consumption of compressed air is very high; although the impact force is strong, the noise level is too high, and the health of field operators is seriously influenced; blowing products using electric energy as power often need frequent maintenance, and have short service life and the like; air knives designed according to the coanda effect ideally solve several of the technical problems described above.

The patent air knife (patent application number: 201410857746.4) designs a linear air knife which comprises two bodies, a plurality of air pipes and at least one first bracket, and the direction is changed by bending the air pipes, so that the problem that the angle is adjusted by repeatedly disassembling and assembling the air knife is solved; an adjustable annular air knife device (patent application number: 201510984737.6) provides an air knife with adjustable air volume of the air knife and small air consumption, has good adaptability, but has a more complex structure; a circular air knife (patent application number: 201711105507.3) is designed to be circular, the direction of the air knife is the periphery and points to the circle center, and a circular welding strip in an air ring is processed in an annular air outlet mode, so that the uniform stress is ensured; a circular air knife (patent application number: 201810781163.6) is designed for processing a circular welding strip, and the circular welding strip penetrates through the middle of the circular air knife and is larger in air receiving area than an air ring, and the received wind power is more uniform.

According to the query of the existing patent, all the air knives are linear or annular, and the direction of the air curtain is that the air curtain blows to the circle center from the outside, so that the air curtain cannot be applied to dust removal and blow drying of the inner wall of the barrel; the invention discloses an annular air knife for cleaning the inner wall of a material container barrel, which is specially designed for dust removal and blow drying of the inner wall of the barrel.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

An annular air knife for cleaning the inner wall of a material container barrel as shown in fig. 1 is composed of an air nozzle 010, an annular air knife 020 and a connecting five-way 030, wherein the connecting five-way 030 is provided with an air inlet and four air outlets at a bifurcation, three air outlets are uniformly distributed on the same plane and are connected with the air inlet of the annular air knife 020, and the rest 1 air outlet is vertically upward and is connected with the air inlet of the air nozzle 010.

As shown in fig. 2, the showerhead 010 comprises an inner ring 011 and an outer ring 012, and inclined vents 014 are opened on the inclined surfaces of the inner ring 011 and the outer ring 012, wherein the inclined vents 014 on the inner ring 011 have a slightly larger inclination angle than the inclined vents 014 on the outer ring, and particularly, a plurality of straight vents are opened right above the inner ring 011; the inner ring 011 and the outer ring 012 are connected with the air inlet below the gas nozzle 010 in the inner cavity, and the gas enters from the air inlet and then is distributed to the inner ring 011 and the outer ring 012, and finally is ejected from the straight air hole 013 and the inclined air hole 014.

As shown in fig. 3 and 4, the annular air knife 020 comprises an upwind blade 021, a gas collecting cavity 022, a downwind blade 023, a size adjusting nail 024, a direction adjusting nail 025, an air outlet cavity 026 and a guide plate 027, compressed air enters from an air inlet, passes through the gas collecting cavity 022 and then suddenly enters the narrow air outlet cavity 026 to form high-speed jet air flow to be jetted from between the upwind blade 021 and the downwind blade 023, and due to the coanda effect, air which is about 30 times as much as the air is guided to the air outlet to form a thin high-strength impact air curtain with atmospheric flow, so that the function of dust removal and blow drying is realized; the gap between the upper air blade 021 and the lower air blade 023 can be changed by adjusting the size adjusting nail 024, so that the size of the air curtain is changed; the direction adjusting nail 025 can change the direction of the guide plate 027 to adjust the impact angle of the air curtain.

Example one

When the interior of the barrel needs to be cleaned, the air knife extends into the inverted barrel, the top of the air knife is stopped when approaching the bottom of the barrel, compressed air is introduced for 10 seconds, the air nozzle 010 removes and dries the bottom of the barrel, the air knife is slowly recovered at a certain speed after 10 seconds, and the impact air curtain of the annular air knife 020 inclines downwards, so that moisture dust adhered to the bottom of the barrel is continuously sent downwards under the high-strength and atmospheric air curtain and finally sent out of the opening of the barrel; at the moment, the compressed air can be closed, the next barrel is waited for, the air knife is sent to the bottom of the barrel, the compressed air is opened, and the process is repeated; if the moisture and dust attached to the inner wall of the barrel are difficult to clean, the proper air quantity and blowing angle can be selected through the size adjusting nail 024 and the direction adjusting nail 025 so as to achieve the satisfactory effect.

As noted above, while the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
