Description
Technical field
The utility model relates to art of filters, is specifically related to a kind of fore filter of plasma cutting fume purifier.
Background technology
The plasma cutting is to utilize the heat of high-temperature plasma electric arc to make the metal local melting (and evaporation) of workpiece incision, and borrow the isoionic momentum of high speed to get rid of motlten metal to form a kind of processing method of otch, extensively apply to all trades and professions such as automobile, locomotive, pressure vessel, chemical machinery, nuclear industry, universal machine, engineering machinery, steel construction, boats and ships.
The plasma cutting cooperates different working gas can cut the metal that various oxygen cuttings are difficult to cut, and is especially better for non-ferrous metal (stainless steel, aluminium, copper, titanium, nickel) cutting effect; When its major advantage was the little metal of cutting thickness, the plasma cutting speed was fast, and especially when cutting normal carbon steel sheet, speed can reach 5～6 times of the oxygen cutting method, cut surface is bright and clean, thermal deformation is little, almost do not have the heat affected area.
Can produce flue dust (ash-laden gas) during the plasma cutting, flue dust can be discharged in the air through after the purification utensil, but plasma cutting flue dust temperature is higher, and contain band Mars particle, the ash-laden gas of high temperature can make the filter material of filter cylinder damage because the Mars particle adheres to if directly entering main filter chamber contacts with filter cylinder, uses under the operating mode of high temperature air for a long time simultaneously, degumming problem appears in the filter cylinder that can make, and influences filter effect and service life.
The utility model content
The utility model provides a kind of fore filter of plasma cutting fume purifier, and the flue dust that the article on plasma cutting produces carries out preliminary filtration, reduces the temperature of flue dust, removes the particle of band Mars, prolongs the service life of follow-up fume purifier.
A kind of fore filter of plasma cutting fume purifier, comprise the filter chamber, the end face of this filter chamber has air inlet, the side has air outlet, inside, described filter chamber is provided with many cooling tubes, the outer wall of every cooling tube and the sidewall of filter chamber are tightly connected, the both ends open of cooling tube and be connected with the outside of filter chamber.
The flue dust that the plasma cutting produces is entered the inside of filter chamber by the air inlet of filter chamber's end face, pass the gap between the many cooling tubes, because the both ends open of cooling tube and with the external communications of filter chamber, filter chamber's air outside enters cooling tube inside, contact with the flue dust in the cooling tube gap, take away the heat of flue dust, the flue dust after the cooling is discharged by the air outlet of side, filter chamber.
Under the situation of the fixed diameter of cooling tube, the quantity of cooling tube is more many, rate of air circulation in all cooling tubes is also more big, the flue dust cooling-down effect is more obvious, the arrangement mode of many cooling tubes can have multiple, evenly flows between each cooling tube in order to make flue dust, preferably, all cooling tubes vertically are divided at least three layers, and at least three cooling tubes are arranged in parallel in every layer.
As preferably, the cooling tube of all layers is parallel to each other, and the diameter of all cooling tubes is identical.
The flue dust of high temperature weaves in the gap of the cooling tube of all layers, carries out sufficient exchange heat with air in the cooling tube.
The quantity of cooling tube is more many, and corresponding cost can increase, and preferably, all cooling tubes vertically are divided into five layers, every layer of four cooling tube that is arranged in parallel.
In order to make flue dust be easy to circuitous advancing in the gap of all cooling tubes, preferably, the dislocation of the cooling tube of adjacent layer is arranged.
In order to ensure the speed that flue dust flows, preferably, the spacing of the cooling tube of adjacent layer is 1～2.5 times of cooling tube diameter.It is 0.4～1 times of cooling tube diameter with the distance between the cooling tube adjacent in one deck.
As preferably, the bottom of described filter chamber is provided with the control of dust tube.
After the outer wall collision of flue dust and cooling tube, under the effect of gravity, oarse-grained dust directly falls in the control of dust tube, is convenient to follow-up focusing on.
As preferably, be connected by falling the ash bucket of truncated cone shape between described filter chamber and the control of dust tube.
Bulky grain thing in flue dust falls in the process of control of dust tube, and ash bucket can prevent that the bulky grain thing from spilling outside the control of dust tube.
The fore filter of the utility model plasma cutting fume purifier, the flue dust that the article on plasma cutting produces carries out preliminary filtration, reduces the temperature of flue dust, removes the particle of band Mars, prolongs the service life of follow-up fume purifier.
Description of drawings
Fig. 1 is the schematic diagram of the fore filter of the utility model plasma cutting fume purifier;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing, the fore filter that the utility model plasma is cut fume purifier is described in detail.
As shown in Figure 1 and Figure 2, a kind of fore filter of plasma cutting fume purifier, comprise filter chamber 2, the end face of this filter chamber 2 has air inlet 1, the side has air outlet 4,2 inside, filter chamber are provided with many cooling tubes 3, and the sidewall of the outer wall of every cooling tube 3 and filter chamber 2 is tightly connected, the both ends open of cooling tube 3 and be connected with the outside of filter chamber 2.
