The utility model discloses simple structure, convenient operation, steam distribute evenly, and with to be taken out gas mixing more even, steam power loss is little, and it is strong to improve evacuation effect practicality.
Description
Technical field
The utility model relates to a kind of novel injection vacuum pump.
Background technique
Steam jet vaccum, because rate of air sucked in required is large, operating range is wide, structure is simple, do not have the parts of relative movement, is a kind of broad-spectrum vacuum equipment, is mainly used in the aspects such as degasification, decolouring, drying, deodorization, distillation, refrigeration and conveying.Particularly it is to suction gas non-selectivity, in food production, petrochemical industry, fats and oils processing, production of polyester, containing occasions such as the material of organic solvent concentrate, demonstrates remarkable advantage compared with oil-sealed rotary pump.
Steam jet vaccum traditional at present adopts single nozzle structure, and distribution of steam is uneven, poor with the mixed effect of pumped gas, affects vacuumizing effect, explosion chamber single stage compression, and the fluctuation of mixed gas velocity variations is comparatively large, and pumping efficiency is low.
Model utility content
The technical problems to be solved in the utility model is to provide the novel injection vacuum pump that a kind of structure simply reduces labor strength.
For solving the problem, the utility model adopts following technological scheme:
A kind of novel injection vacuum pump, comprise the pump housing, protective cover, Diffuser, nozzle box, nozzle, connecting bolt, uperize import, pumped gas mouth, insulation steam (vapor) outlet, insulation steam inlet and relief opening, the described pump housing is provided with pump case, described pump case is connected with protective cover by connecting bolt, described pump body is provided with nozzle box, uperize import is connected with on the left of the described pump housing, described uperize import top is provided with nozzle, pumped gas mouth is connected with above the described pump housing, described protective cover inside is provided with Diffuser, insulation steam inlet is connected with above described Diffuser, insulation steam (vapor) outlet is connected with below described Diffuser, relief opening is provided with on the right side of described Diffuser.
As preferably, described Diffuser is connected with nozzle box by pipeline.
As preferably, described uperize import, pumped gas mouth, insulation steam (vapor) outlet, insulation steam inlet and relief opening are provided with control valve.
The utility model structure is simple, easy to operate, more economizes the energy; Environmental protection, life-span length, maintenance are simply; Distribution of steam is even, and mix more even with pumped gas, steam power loss is little, improves vacuumizing effect practical.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings;
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, a kind of novel injection vacuum pump, comprise the pump housing 1, protective cover 2, Diffuser 3, nozzle box 4, nozzle 5, connecting bolt 6, uperize import 7, pumped gas mouth 8, insulation steam (vapor) outlet 9, insulation steam inlet 10 and relief opening 11, the described pump housing 1 is provided with pump case, described pump case is connected with protective cover 2 by connecting bolt 6, the described pump housing 1 inside is provided with nozzle box 4, uperize import 7 is connected with on the left of the described pump housing 1, described uperize import 7 top is provided with nozzle 5, pumped gas mouth 8 is connected with above the described pump housing 1, described protective cover 2 inside is provided with Diffuser 3, insulation steam inlet 10 is connected with above described Diffuser 3, insulation steam (vapor) outlet 9 is connected with below described Diffuser 3, relief opening 11 is provided with on the right side of described Diffuser 3, the described pump housing 1 is provided with maintenance window.
It should be noted that described Diffuser 3 is connected with nozzle box 4 by pipeline.
It should be noted that and described uperize import 7, pumped gas mouth 8, insulation steam (vapor) outlet 9, insulation steam inlet 10 and relief opening 11 are provided with control valve.
Its working procedure can be divided into three phases: adiabatic expansion stage, mix stages, compression stage.
In the adiabatic expansion stage, working steam is by after contraction and enlargement nozzle, and pressure energy is converted into speed energy, enters Diffuser with high speed, and the pressure of working steam declines at nozzle exit simultaneously, forms vacuum and pumped gas is sucked;
Mix stages, pumped gas enters Diffuser, and in Diffuser, steam collides with pumped gas, mix, and carry out energy interchange, to Diffuser, throat completes mixing, and two kinds of gases reach same speed;
Compression stage, after Diffuser throat, mixed gas speed reduces, and pressure rises further, reaches the inlet pressure of atmospheric pressure or rear stage sparger, pumped gas is discharged at diffuser exit.
The standardized element that the utility model uses all can be commercially, special-shaped part all can carry out customized according to specification with the record of accompanying drawing, the concrete Placement of each part all adopts the conventional means such as bolt, rivet, welding ripe in prior art, machinery, part and equipment all adopt in prior art, conventional model, add that circuit connects and adopt Placement conventional in prior art, be not described in detail in this.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
