Abstract

The utility model relates to an air jet imbibition device, which comprises a casing, an air inlet pipe, a spray pipe, a mixed flow discharge pipe and an imbibition head, wherein the casing is formed by a front casing and a back casing whose cavities are communicated, the spray pipe is installed in the front casing, an absorbing chamber is formed between the spray pipe and the front casing, and the imbibition head is communicated with the absorbing chamber. A shrinking chamber, a diffusing chamber and an expanding chamber are arrayed in turn in the cavity of the back casing, wherein the shrinking chamber takes on a cone which is shrinks gradually, the cavity diameter of the expanding chamber is larger that the diffusing chamber, the air inlet pipe is connected on the inlet of the spray pipe, and the mixed flow discharge pipe is connected on the tail end of the expanding chamber in the back casing. The device can effectively absorb cutting fluid which is dripped to be reuse according to the principle of generating vacuum by air jet, which not only saves cost, but also reduces the pollution for working environment, solves the pollution to environment which is caused by inevitable factors such as liquid leaking, dripping and sprinkling in production operation environment or the potential safety hazards, and has the advantages of simple structure, small volume, excellent sealing, easy production, simple operation, no need of electricity, non abrasion and free maintenance.

Description

A kind of air-spray liquid sucking device

Technical field

The utility model relates to a kind of raffinate absorption plant, is specifically related to a kind of absorb in the industrial production operating environment and leaks, drips, spills the medium pollution that produced or the device of raffinate.

Background technique

In modernized mass production operation, produce line all is continuous productive process basically, machine adds manufacturing mechanism all will use cutting fluid, behind the reprocessing apparatus processing product, product is taken away some cutting fluids, working medium inevitably and is distributed in the operating environment by modes such as leaking, drip, spill when mobile on production line, cause environmental pollution on the one hand, also cause waste on the other hand, also can cause potential safety hazard, the present invention just is being based on a kind of novel air jet liquid sucking device that addresses the above problem and produce.

Summary of the invention

The purpose of this utility model provides a kind of air-spray liquid sucking device that is used to absorb raffinate, adopts this liquid sucking device, utilizes after the working medium that leaks in the working environment, drips, spills being absorbed again, and avoids environmental pollution, waste and formation potential safety hazard.

The purpose of this utility model is achieved like this:

A kind of air-spray liquid sucking device, include housing, suction tude, injection pipe, mixed flow discharge tube and imbibition head, described housing is connected and composed by front case and the rear case that inner chamber communicates, injection pipe is contained in the front case, and between injection pipe and front case inner chamber, forming absorption chamber, the imbibition head is communicated with absorption chamber; Described rear case inner chamber is divided into retract chamber, explosion chamber and expansion chamber successively in the past backward, and retract chamber is diminishing taper, and the footpath, chamber of expansion chamber is greater than explosion chamber; Described suction tude is connected the injection pipe import, and the mixed flow discharge tube is connected rear case expansion chamber end.

The working principle of this device is: when pressurized air is flowed through injection pipe, form higher injection rate at the nozzle place, thereby in absorption chamber, produce vacuum, the sucked liquid absorption is entered absorption chamber, pass through retract chamber and explosion chamber again, enter in the expansion chamber after making air and sucked liquid fully mixing, at this moment mixed-fluid pressure raises and reaches atmospheric pressure, discharge from the mixed flow discharge tube at last, finished the whole process of compressed air jet imbibition.

This device is with the vacuum principle of air-spray, the liquid that dexterously leakage is spilt absorbs the back and concentrates, can be effectively the cutting fluid of water clock be absorbed again and utilize, the pollution of not only having saved cost but also having alleviated operating environment has solved in the manufacturing operation environment pollution or potential safety hazard that factors such as inevitable liquid leaks, drips, spills cause to environment.This installs the flexible pipe of all connecting pipelines according to the different available any materials of suction medium, and can move to any accessible position, have very strong applicability, and simple in structure, volume is little, good airproof performance, making are easy, simple to operate, need not electric energy, do not have advantages such as wearing and tearing, Maintenance free.

This device also can be used for the raffinate of liquid such as the high-risk medium in inflammable and explosive operation place such as gasoline, kerosene, alcohol, ethylene glycol to be collected, and also can be used for siphoning away unnecessary gasoline after the motor break-in, and purposes is very extensive.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Referring to Fig. 1, this apparatus structure mainly is made up of 7 parts, and the 1st, suction tude, the 2nd, injection pipe, the 3rd, front case forms absorption chamber, and the 4th, rear case forms retract chamber, explosion chamber and expansion chamber, the 5th, the mixed flow discharge tube, the 6th, pick-up tube, the 7th, sucker is used for fixing pick-up tube.

Wherein front case 3 and rear case 4 connect and compose a whole housing, their inner chamber communicates, injection pipe 2 is contained in the front case 3, and between injection pipe 2 and front case 3 inner chambers, form absorption chamber A, rear case 4 inner chambers are divided into retract chamber B, explosion chamber C and three work chamber of expansion chamber D successively in the past backward, wherein retract chamber B is diminishing taper, and the spray nozzle front end 8 of injection pipe 2 puts among the retract chamber B, and footpath, the chamber of expansion chamber D is greater than explosion chamber C.Suction tude 1 is connected injection pipe 2 imports, and mixed flow discharge tube 5 is connected the end of the expansion chamber D of rear case 4, and pick-up tube 6 is connected with front case 3, is communicated with absorption chamber in it, and sucker 7 is fixed on pick-up tube 6 lower ends.

During manufacturing; distinguish Vehicle Processing injection pipe 2, front case 3 and rear case 4; injection pipe 2 outsides are milled out six sides; be used to regulate the position of injection pipe top nozzle; to guarantee to obtain desirable assimilation effect; sucker 7 is milled processing; liquid sucting port is enlarged; being more conducive to sucked liquid can be to greatest extent near pick-up tube suction inlet place; increase absorption efficiency; according to different media and field conditions assembling compressed air inlet pipe 1, mixed flow discharge tube 5 and pick-up tube 6, notice that each joint must not leak gas then, guarantee that sealing could guarantee the imbibition effect.

This device boundary dimension can be very little, being preferably radial dimension is φ 30～50mm, on the length direction 200～300mm, the compressed air pressure range of needs is 3～7bar, the ratio that absorbs flow and comsumption of compressed air can be from 5: 1～1: 1, and imbibition lifting height scope is 0～1.5 meter.
