Abstract

The utility model belongs to the technical field of traps, and discloses a double-sleeve trap. The main technical characteristics are that the double-sleeve trap comprises an inner filtering barrel and an outer filtering barrel which is sleeved outside the inner filtering barrel, wherein the upper end of the inner filtering barrel is plugged, and the lower end of the inner filtering barrel is open; the lower end of the outer filtering barrel and the lower end of the inner filtering barrel are sealed through a plugging ring; an upward sandwich gas passage is formed between the inner filtering barrel and the outer filtering barrel; a part of gas with material dust enters the inner filtering barrel through the opening in the lower end of the filtering barrel and then is filtered through the inner filtering barrel, so that the material dust is stopped inside the inner filtering barrel, and the gas is discharged out of drying equipment through the sandwich gas passage between the inner filtering barrel and the outer filtering barrel; the other part of gas with the material dust is filtered by the outer filtering barrel, so that the material dust is stopped outside the outer filtering barrel, and the gas is discharged out of the drying equipment through the sandwich gas passage between the inner filtering barrel and the outer filtering barrel; and thus, the filtering area is greatly increased, the trapping effect is good, the used gas pressure is reduced to facilitate collection in a collection process.

Description

Two sleeve traps

Technical field

The utility model belongs to the trap technical field, relates to specifically a kind of two sleeve traps for filtration.

Background technology

In fields such as bio-pharmaceuticals, food, when material is carried out drying, above drying equipment, be provided with trap, discharge with air-flow to prevent material, both prevented the waste of material, and prevented from air is polluted.The trap that uses at present is generally tubular, in the capture process, has following defective: one, filter area is little, captures weak effect, its two, when collecting, need gas pressure large, collect inconvenient.

The utility model content

The technical problem that the utility model solves just provides two sleeve traps that a kind of filter area is large, capture is effective, be convenient to collect.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise inner filtration bucket and the outer filter vat that is enclosed within this inner filtration bucket outside, the upper end shutoff of described inner filtration bucket, lower ending opening; The lower end of described outer filter vat lower end and described inner filtration bucket forms interlayer gas passage upwards by the sealing of shutoff ring between described inner filtration bucket and described outer filter vat.

Its additional technical feature is:

Between the described inner filtration bucket above the interlayer gas passage of described upper end and described outer filter vat, be provided with bracing frame.

Two sleeve traps that the utility model provides, comparing with prior art has the following advantages: one, owing to comprise the inner filtration bucket and be enclosed within the outer filter vat in this inner filtration bucket outside, the upper end shutoff of described inner filtration bucket, lower ending opening; The lower end of described outer filter vat lower end and described inner filtration bucket seals by the shutoff ring, between described inner filtration bucket and described outer filter vat, form interlayer gas passage upwards, a part enters in the inner filtration bucket with the opening of gas through inner filtration bucket lower end of material dust, then filter through the inner filtration bucket, it is inboard that material dust is blocked in the inner filtration bucket, the interlayer gas passage of gas between inner filtration bucket and outer filter vat discharged drying equipment, another part filters through outer filter vat with the gas of material dust, material dust is blocked in the outer filter vat outside, the interlayer gas passage of gas between inner filtration bucket and outer filter vat discharged drying equipment, filter area increases greatly, capture effective, in collection process, the gas pressure of use reduces, and is convenient to collect; Its two owing to be provided with bracing frame between the described inner filtration bucket above the interlayer gas passage of described upper end and described outer filter vat, in dry run, when steam pressure was large, inner filtration bucket and outer filter vat were not easy distortion, filtering accuracy is stablized.

Description of drawings

Fig. 1 is the structural representation of two sleeve traps;

The top view of the two sleeve traps of Fig. 2.

The specific embodiment

The structure of the two sleeve traps that the utility model proposed below in conjunction with accompanying drawing is described further.

As depicted in figs. 1 and 2, be the structural representation of two sleeve traps.Its structure comprises inner filtration bucket 1 and the outer filter vat 2 that is enclosed within this inner filtration bucket 1 outside, and the upper end of inner filtration bucket 1 is by upper cover 3 shutoff, and the lower end of inner filtration bucket 1 is inner filtration bucket end opening 6; The lower end of the lower end of outer filter vat 2 and inner filtration bucket 1 forms interlayer gas passage 5 upwards by 4 sealings of shutoff ring between inner filtration bucket 1 and outer filter vat 2.A part enters in the inner filtration bucket 1 with the inner filtration bucket end opening 6 of gas through inner filtration bucket 1 lower end of material dust, then filter through inner filtration bucket 1, material dust is blocked in the inboard of inner filtration bucket 1, the interlayer gas passage 5 of gas between inner filtration bucket 1 and outer filter vat 2 discharged drying equipment, another part filters through outer filter vat 2 with the gas of material dust, material dust is blocked in the outside of outer filter vat 2, the interlayer gas passage 5 of gas between inner filtration bucket 1 and outer filter vat 2 discharged drying equipment, filter area increases greatly, capture effective, in collection process, the gas pressure of use reduces, and is convenient to collect.

Protection domain of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the two sleeve trap structures of the utility model, just drops on the scope of the utility model protection.

Claims

1. two sleeve traps is characterized in that: comprise inner filtration bucket and the outer filter vat that is enclosed within this inner filtration bucket outside, the upper end shutoff of described inner filtration bucket, lower ending opening; The lower end of described outer filter vat lower end and described inner filtration bucket forms interlayer gas passage upwards by the sealing of shutoff ring between described inner filtration bucket and described outer filter vat.

2. according to claim 1 pair of sleeve trap is characterized in that: be provided with bracing frame between the described inner filtration bucket above the described interlayer gas passage and described outer filter vat.
