Abstract

The utility model discloses a loader with a quick loading speed. The loader comprises an outer pipe and an inner pipe which is arranged in the outer pipe, wherein a cavity is arranged between the outer pipe and the inner pipe; an air inlet pipe which is used for communicating the cavity with the outside of the outer pipe is arranged on the outer pipe; a gap is formed between the outer wall of one end of the inner pipe and the inner wall of the outer pipe; the gap is used for communicating the cavity with the inside of the outer pipe; the range of the gap is 0.03-1mm. The loader has the advantages that the cavity and the gap are combined, the compressed air is ejected from the gap, a negative pressure is formed in the inner pipe, materials are taken away, the structure is simple, no complicated drive device is needed, only one air compressor is needed, and the loading speed is rapid.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of material loading fireballing loader.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of loader, comprise outer tube and inner tube is within the outer tube set, between outer tube and inner tube, be provided with a cavity, on outer tube, be provided with the air inlet pipe that is communicated with cavity and the outer tube external world, gapped between the outer wall of one end of inner tube and outer tube wall, this gap is communicated with cavity and outer tube is inner, and interstice coverage is 0.03～1mm.

Between described gap and cavity, by an annular passage, be connected, half of the vertical section of passage is trapezoidal shape, and trapezoidal tapering is 2 °～5 °, and trapezoidal upper base is connected with gap, goes to the bottom and is connected with cavity.

Described trapezoidal tapering is 3 °.

A described trapezoidal hypotenuse and outer axial tube are to being outwards 5 °, and another hypotenuse and outer axial tube are to being outwards 8 °.

Described cavity is divided into two little cavitys, and one of them little cavity is connected with air inlet pipe, and another little cavity is connected with gap, and by gap, communicates between two little cavitys, and the scope in gap is 0.3～1.5mm.

The scope in described gap is 0.6～0.7mm.

The described little cavity being connected with air inlet pipe is met to the position of air inlet pipe curved.

Described inner tube wall is bell mouth shape.

Described interstice coverage is 0.05～0.1mm.

The beneficial effects of the utility model are: utilize the combination in cavity and gap, pressurized air is sprayed from gap location, thereby form negative pressure in inner tube, material is taken away, and the utility model is simple in structure, without complicated actuating device, as long as an air compressor, material loading speed is fast.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of loader, comprise outer tube 8 and be arranged on the inner tube 9 in outer tube 8, between outer tube 8 and inner tube 9, be provided with a cavity, in actual production, in order to stablize air pressure, cavity is divided into two little cavitys---the first loculus body 2 and the second loculus body 4, between the first loculus body 2 and the second loculus body 4, by gap 5 (gap scope is 0.3～1.5mm, is preferably 0.6～0.7mm), be connected.On outer tube, be provided with the air inlet pipe 1 that is communicated with cavity and outer tube 8 external worlds, in the present embodiment, the first loculus body 2 is connected with air inlet pipe 1, between the outer wall of the interior middle and upper part of outer tube 8 and this end and outer tube 8 inwalls, gapped 3 (interstice coverage is 0.03～1mm in the upper end of inner tube 9, be preferably 0.05～0.1mm) (injection orifice), this gap 3 is communicated with the first loculus body 2 and outer tube 8 inside.The upper end of outer tube 8 is discharging opening 7, and the lower end of inner tube 9 is inlet point 6, and inlet point 6 is bell mouth shape, and described inner tube 9 inwalls are bell mouth shape.

In order to make the negative pressure of air-flow generation the most desirable, it is maximum that the operational throughput of per minute reaches, between described gap 3 and the second loculus body 4, by an annular path 10, be connected, half of the vertical section of path 10 is trapezoidal, because path 10 is an annular, therefore when describing in order to understand conveniently, half of the vertical section of path 10 is trapezoidal, as shown in Figure 2 concrete.Trapezoidal tapering is 2 °～5 °, and trapezoidal upper base is connected with gap 5, goes to the bottom and is connected with the second loculus body 4.It would be desirable that described trapezoidal tapering is that F-E=3 ° and a described trapezoidal hypotenuse (outer wall of inner tube 9) are axially outwards 5 ° (E) with outer tube 8, another hypotenuse (inwall of outer tube 8) is axially outwards 8 ° (F) with outer tube 8.In gap 3 scopes, it is 0.05～0.1mm and the gap scope concrete following form 1 of Contrast on effect be 0.6～0.7mm in the situation that

Form 1

In order further to improve the stability of the air pressure in the second loculus body 4, described the first loculus body 2 is met to the position of air inlet pipe 1 curved.

Working process of the present invention is: utilize air compressor that the air after compression is entered the first loculus body 2 from air inlet pipe 1, after the first loculus body 2 voltage stabilizings, air after voltage stabilizing enters the second loculus body 4 from gap 5, then through path 10 3 (injection orifice) ejection from gap, because air is upwards to spray, therefore in negative pressure of the interior formation of inner tube 9, material just moves up under the effect of air from inlet point 6 and from discharging opening 7 out fast.Because pressurized air provides power, whole feeding process does not have noise, and not electricity consumption, there is no electric interference, without electric hidden danger.Simple to operate, non-maintaining, can be used for the remote convey materials of flow-quantity high-efficiency rate greatly, simple and compact for structure, volume is little, lightweight, is convenient to install.Possess high circulating capacity, utilize pressure regulator to control material transferring.Pure physical construction, does not have movable parts, safe and reliable, long service life.
