Abstract
The utility model belongs to the field of air refreshing filter devices and relates to a centrifugal separation filter device of an oil mist collecting filter. The centrifugal separation filter device of the oil mist collecting filter comprises a thin-wall cylindrical flow divider and a thin-wall round table shaped spiral separator, wherein the thin-wall cylindrical flow divider is fixedly arranged on the inner surface of an air inlet of the oil mist filter; the thin-wall round table shaped spiral separator is arranged in an inner cavity of the thin-wall cylindrical flow divider; the thin-wall round table shaped spiral separator is directly connected with a liquid return tube and arranged on the lower end part of the thin-wall round table shaped spiral separator; one end of the spiral separator is sealed and the other end of the spiral separator is semi-open; the semi-open surface is connected with an oil return tube; and the liquid return tube is arranged on the lower end part of the thin-wall round table shaped spiral separator. The centrifugal separation filter device of the oil mist collecting filter is a filter element without a filter material; the oil mist filtration yield can reach about 70%; the service life of the oil mist collecting filter can be prolonged by 300% or more; the using cost of the oil mist colleting filter is greatly lowered, and therefore, the centrifugal separation filter device is beneficial to wide popularization of the oil mist collecting filter in a workshop and also beneficial to the national environmental protection.
Description
Technical field
The utility model belongs to filter plant with fresh air field, relates to a kind of mist of oil de-entrainment filter centrifugation filter.
Background technology
In mechanical processing industry, usually need the part in the processing is cooled off, this just need spray a large amount of emulsions, cooling wet goods cooling fluid to workpiece.Cooling fluid can produce a large amount of aerosol and carry tiny dust secretly and be diffused in the air when high-pressure injection, this respiratory system to the plant operations personnel causes very big harm.In the prior art, rely on built-in each layer filtering material of oil mist filter that it is collected, handles to the method for the collection and treatment of mist of oil and dust granules.In the actual production practice, the size particles mist of oil that built-in each layer filtering material is easy to be collected and the mixture of dust stop up and cause effect that mist of oil collects, handles in time passing and poor effect, usually solving the way of stopping up is constantly to change each layer filtering material, and change the shell that each layer filtering material need be taken machine apart, so just need the professional to implement maintenance work, exist many shortcomings such as workload is big, cost is high, enforcement inconvenience in the maintenance.In addition, constantly change each layer filtering material, also caused the use cost of oil mist filter higher, be unfavorable for the extensive universal of oil mist filter, also be unfavorable for the development of Environmental Protection in China cause.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of mist of oil de-entrainment filter centrifugation filter simple in structure, ingenious, rational is provided, this device uses the centrifugation filter that most of mist of oil is collected, the residue fraction allows each layer filtering material collect again, reduces greatly and safeguards use cost.
The technical scheme that provides according to the utility model: a kind of mist of oil de-entrainment filter centrifugation filter, it is characterized in that: comprise being fixedly installed in oil mist filter air inlet inner surface thin walled cylindrical current divider; thin-walled truncated cone-shaped spiral separator; thin-walled truncated cone-shaped spiral separator places thin walled cylindrical current divider inner chamber, described thin-walled truncated cone-shaped spiral separator directly are connected with liquid back pipe and place thin-walled truncated cone-shaped spiral separator bottom.
As further improvement of the utility model, described thin-walled truncated cone-shaped spiral separator one end is half unlimited shape for the sealing other end, and half opens wide the shape face takes back oil pipe.
As further improvement of the utility model, liquid back pipe is in the bottom of thin-walled truncated cone-shaped spiral separator.
The utility model compared with prior art; advantage is: the utility model is a kind of filter element that does not have filtering material; the mist of oil filtration yield can reach about 70%; improved more than 300% the service life of mist of oil de-entrainment filter; the use cost of mist of oil de-entrainment filter reduces greatly; be conducive to the mist of oil de-entrainment filter and popularize the extensive of workshop, also be conducive to the environmental protection of China.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of thin-walled truncated cone-shaped spiral separator 2.
1. thin walled cylindrical current dividers, 2. thin-walled truncated cone-shaped spiral separators, 3. liquid back pipes among the figure
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1, the utility model is a kind of mist of oil de-entrainment filter centrifugation filter, comprises thin walled cylindrical current divider 1, thin-walled truncated cone-shaped spiral separator 2, liquid back pipe 3.Thin-walled truncated cone-shaped spiral separator 2 places thin walled cylindrical current divider 1 inner chamber, and thin-walled truncated cone-shaped spiral separator 2 directly is connected with liquid back pipe 3 and places thin-walled truncated cone-shaped spiral separator 2 bottoms.The centrifugation filter at the mist of oil de-entrainment filter with respect to the collection material layer, it can carry out primarily efficient filter to the bulky grain molecule that contains in the mist of oil, make the mist of oil molecule that enters in the oil mist filter body of wall that reduction significantly arranged on particle size and oil mist concentration, reduced the pressure of other filter courses.
As shown in Figure 2, thin-walled truncated cone-shaped spiral separator 2 one ends are half unlimited shape for the sealing other end, and half opens wide the shape face takes back oil pipe 3, and the mist of oil that thin-walled truncated cone-shaped spiral separator 2 filters flows out by liquid back pipe 3.
It is outside or inner that the utility model mist of oil de-entrainment filter centrifugal separating device can be placed on oil mist filter, can tackle the 70%-80% of total treating capacity after the filtration, need not cleaning simultaneously and change element.The utility model in use cost is low, convenient, simple, does not need the professional and technical personnel to safeguard.The use cost of oil mist filter reduces greatly, is conducive to oil mist filter and popularizes the extensive of workshop, also is conducive to the environmental protection of China.
