Description

Oil crumb vacuum cleaner

Technical Field

The utility model relates to an oil bits dust catcher in air purifier equipment field.

Background

In the industrial processing production, a large amount of dust fragments are generated, the dust fragments can contain oil mist liquid, particularly in the metal processing process of turning, milling, drilling, grinding and the like, due to the use of the metal cutting fluid, a large amount of oil mist particles are formed in the air, the oil mist particles sucked in can reach and deposit on the lung to cause adverse reaction, the smaller the particles are, the more polycyclic aromatic hydrocarbons and heterocyclic compounds are contained, the greater the harm is, and diseases such as lung cancer and the like can be caused; and after the machine is polluted by oil dust, the service life of the machine is shortened, and the production efficiency is also reduced. The traditional dust collector can only filter dust and large oil mist particles, has no filtering function on small oil mist particles, and has electrostatic purification equipment at present, low purification efficiency and high energy consumption, and the used electrostatic liquid easily produces secondary pollution.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, an object of the present invention is to provide an oil crumb vacuum cleaner which has a high purification rate, can separate oil crumb, and does not produce secondary pollution.

The utility model discloses a realize through following technical scheme:

the utility model provides an oil bits dust catcher, includes frame, host computer, collecting tank and dust collection bucket, and the host computer is installed in the frame, and collecting tank and dust collection bucket are installed on the host computer, are equipped with the vacuum unit in the host computer, and the dust collection bucket passes through the pipeline to be connected its characterized in that with the vacuum unit: a filter is arranged in the dust collection barrel, a scrap collecting barrel is arranged in the filter, a liquid storage layer is arranged at the bottom of the filter, liquid in the liquid storage layer is conveyed to the liquid collection barrel through a centrifugal pump, a suction inlet is formed in the dust collection barrel, oil scraps enter the dust collection barrel through the suction inlet and are separated through the filter, the scraps flow into the liquid storage layer at the bottom of the filter in the scrap collecting barrel, and the liquid in the liquid storage layer is conveyed to the liquid collection barrel through the centrifugal pump; the technical scheme is further explained as follows: a liquid level switch is arranged in the liquid collecting barrel, the liquid level switch is connected with a host controller in a signal mode, when the liquid level reaches the maximum position, the liquid level switch can stop the dust collector when in operation, meanwhile, the liquid level switch floats upwards to close the outlet of the scrap collecting barrel, liquid is prevented from overflowing, and when the liquid reaches the lowest position of the liquid level meter, liquid discharging is stopped; the technical scheme is further explained as follows: the scrap collecting barrel is a portable scrap collecting barrel; the technical scheme is further explained as follows: the air outlet of the host vacuum unit is provided with an oil mist purifier, the oil mist purifier consists of a pre-filtering layer and a fine filtering layer, the pre-filtering layer is a stainless steel wire mesh, the fine filtering layer is a non-woven fabric layer, sucked liquid flows into the liquid storage layer, and residual trace oil mist in the air is finally filtered again through the fine filtering layer, so that a purification process is completed.

The utility model has the characteristics of dust absorption and the filterable dual function of oil mist and can not discharge toxic gas or harmful radiation etc.

Drawings

FIG. 1 is a schematic diagram of the structure of the oil dust collector.

Fig. 2 is a view showing the inner structure of the dust collecting barrel.

Fig. 3 is a structural view of the oil mist purifier.

In the figure: the device comprises a frame 1, a host machine 2, a dust collecting barrel 3, a liquid collecting barrel 4, a suction inlet 5, an air outlet 6, an oil mist purifier 7, a filter 8, a liquid level switch 9, a liquid storage layer 10, a pre-filtering layer 11 and a fine filtering layer 12.

Detailed Description

The invention will be further explained with reference to the accompanying drawings:

as shown in the figure, the oil scrap dust collector is a schematic diagram of a connection structure of the oil scrap dust collector, and comprises a frame 1, a host machine 2, a dust collecting barrel 3, a liquid collecting barrel 4, a suction inlet 5, an air outlet 6, an oil mist purifier 7, a filter 8, a liquid level switch 9, a liquid storage layer 10, a pre-filtering layer 11 and a fine filtering layer 12, wherein the oil scrap dust collector is an industrial dust collector and can absorb mixed solid liquid or only absorb liquid, the suction inlet on the dust collecting barrel is connected with an oil-resistant rubber tube when absorbing the mixed solid liquid, the dust collector is arranged on a movable frame, if the positioning placement is adopted, a wide area is selected to facilitate the movement and maintenance work of the dust collector, the dust collector collects dust through strong airflow generated by an exhaust fan in a vacuum unit, the oil scrap dust is filtered by a filter screen in the dust collecting barrel, the oil scrap dust is collected in the dust collecting barrel, the oil mist liquid flows into the, liquid in the liquid storage layer is conveyed into the liquid collecting barrel through a centrifugal pump; the gas containing oil mist is filtered by an oil mist purifier on the air outlet of the host machine and is discharged from the air outlet, a liquid level switch is arranged in the liquid storage layer, a signal of the liquid level switch is connected with the host machine controller, when the liquid level reaches the maximum position, the host machine controller can shut down the dust collector during operation, and meanwhile, the liquid level switch floats upwards to close a liquid discharge port of the dust collection barrel, so that liquid overflow is prevented. The liquid in the liquid storage layer is conveyed to the liquid collecting barrel through the centrifugal pump, and the liquid stops being discharged when the liquid reaches the lowest position of the liquid level meter. The oil mist clarifier comprises prefilter layer and fine filter layer, the air that contains the oil mist carries out the primary filtration to the oil mist through the prefilter layer earlier, the oil mist that is filtered condenses into oil and drips the inner wall that attaches to the filter box slowly and forms oil, these oil drip slowly lead in the hydraulic fluid port flows into the collecting vessel through well, air filters once more through the filter layer at last, filter surplus trace oil mist in the air, accomplish the purification treatment and discharge, the prefilter layer is fine stainless wire net, the fine filter layer is the non-woven fabrics layer, the non-woven fabrics layer can take out and change, the oil mist is gaseous to accomplish the air purification process through the oil mist clarifier, then discharge by the air outlet.

Various modifications to the above-described techniques will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
