Abstract
The utility model relates to a powder and particle material transport vehicle discharging blowing-assisting device, and belongs to the technical field of pneumatic conveying. The powder and particle material transport vehicle discharging blowing-assisting device comprises a discharging inside communication pipe, an outer sleeve taper pipe is installed on the outer ring of the inside communication pipe, the large end of the outer sleeve taper pipe is in sealed connection with one end of the inside communication pipe, and a tapered air chamber is formed between the inside communication pipe and the outer sleeve taper pipe; and the outer sleeve taper pipe is provided with a hole, and a ventilation joint is installed on the hole. According to the powder and particle material transport vehicle discharging blowing-assisting device, compressed air is enabled to enter into the tapered air chamber through the ventilation joint, and mixtures of powder and particle materials and air enter into the powder and particle material transport vehicle discharging blowing-assisting device, wherein the mixtures of powder and particle materials and the air are conveyed through air pressure wind. The compressed air and the mixtures of the powder and particle materials and the air are mixed, the air-material mixing ratio of the mixtures of the powder and particle materials and the air is increased, the flow rate is accelerated at the same time, powder and particle material conveying blowing assistance is achieved, and negative pressure and material conveying dead angles are eliminated simultaneously.
Description
Technical field
The utility model relates to a kind of bulk powder goods tanker discharging auxiliary blowing apparatus, belongs to the Pneumatic Conveying Technology field.
Background technology
In the prior art, the pot type bulk powder goods tanker, such as bulk cement car, flour transport trolley, unloading vehicle etc., the air pressure blowing-type is all adopted in its tank body discharging.For making the powder grain material fast discharging, generally on the discharge duct of bulk powder goods tanker, all install auxiliary blowing apparatus additional, but the structure of auxiliary blowing apparatus is often unreasonable, often forms negative pressure or dead angle, hindered on the contrary flowing of powder grain material; Also can cohere the more poly-larger last obstruction conveying pipeline at the dead angle for the larger material of some stickiness such as flour, cement.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of bulk powder goods tanker discharging auxiliary blowing apparatus is provided, and when helping of realizing powder grain material is carried blown, stopped the generation at negative pressure and conveying dead angle fully.
In order to solve above technical matters, the utility model provides a kind of bulk powder goods tanker discharging auxiliary blowing apparatus, comprise siphunculus in the discharging, in described interior siphunculus outer ring the overcoat Taper Pipe is set, adopt sealing to be connected between the large end of described overcoat Taper Pipe and the end of interior siphunculus, formation taper air chamber between described interior siphunculus and the described overcoat Taper Pipe; Perforate on described overcoat Taper Pipe arranges ventilating joint on the described hole.
The technical scheme that the utility model further limits is: aforesaid bulk powder goods tanker discharging auxiliary blowing apparatus, described overcoat Taper Pipe is longer than described interior siphunculus, the part that the interior siphunculus of overcoat Taper Pipe grows forms mixing zone, so that powder grain material air mixture gas material mixture ratio increases simultaneously flow velocity quickening, realize helping blowing function.
Aforesaid bulk powder goods tanker discharging auxiliary blowing apparatus for the ease of installation and repairing, is equipped with flange or mounting plate at the closed end of described overcoat Taper Pipe.
Further, aforesaid bulk powder goods tanker discharging auxiliary blowing apparatus adopts welding manner to connect between described overcoat Taper Pipe and the interior siphunculus.
The beneficial effects of the utility model are: the utility model is by passing into pressure gas at inlet suction port in the taper air chamber, and the powder grain material air mixture that air pressure wind send enters described bulk powder goods tanker discharging auxiliary blowing apparatus by interior siphunculus.Described pressurized air is mixed with described powder grain material air mixture, so that described powder grain material air mixture gas material mixture ratio increases simultaneously flow velocity quickening, when realization is blown helping of powder grain material conveying, stopped the generation at negative pressure and conveying dead angle fully.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is front view of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
A kind of bulk powder goods tanker discharging auxiliary blowing apparatus that present embodiment provides, structure as shown in Figure 1 to Figure 3, comprise end flanges 1 and the interior siphunculus 2 of discharging that is welded on the end flanges inner ring, at interior siphunculus 2 outer ring solder mask Taper Pipes 4, overcoat Taper Pipe 4 is longer than interior siphunculus 2, the part that the interior siphunculus of overcoat Taper Pipe 4 grows forms mixing zone 5, so that powder grain material air mixture gas material mixture ratio increases simultaneously flow velocity quickening, realization helps blows function; The large end sealing of overcoat Taper Pipe 4 is connected on the end flanges 1, forms taper air chamber 6 between interior siphunculus 2 and the overcoat Taper Pipe 4; Perforate on overcoat Taper Pipe 4 arranges ventilating joint 3 on the hole, the external pressure gas of ventilating joint.
In the time of in actual the use, the outlet position that the bulk powder goods tanker discharging auxiliary blowing apparatus of present embodiment can be installed on the bulk powder goods tanker discharge duct connects by end flanges, other end welding discharge duct.During the bulk powder goods tanker discharging, in taper air chamber 6, pass into pressure gas by inlet suction port 3, and the powder grain material air mixture that air pressure wind send enters bulk powder goods tanker discharging auxiliary blowing apparatus by interior siphunculus 2, pressurized air is mixed at mixing zone 5 with the powder grain material air mixture, so that powder grain material air mixture gas material mixture ratio increases simultaneously flow velocity quickening, realize helping blowing function.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
