Description
Technical Field
The utility model relates to a technical field of exhaust emission handles, more specifically says that it relates to a repeatedly usable's exhaust treatment device.
Background
Carry out the in-process of preparing to compound in the laboratory, can produce waste gas, in order to reach the requirement of emission, can handle waste gas, current sets up miniature dust excluding hood through the instrument top of preparing at compound to settle the dust removal sack in the dust excluding hood and realize the adsorption and filtration to waste gas.
In the installation process of the existing dust removal cloth bag and the dust removal cover, the dust removal cloth bag is attached to the inner wall of the dust removal cover, nail holes are reserved in the dust removal cover, and the cloth bag and the dust removal cover are fixed through rivets.
The rivet needs to be removed when the dust removal cloth bag is replaced, and the replacement is very inconvenient. Therefore, the dust removal cloth bag is installed in a laboratory through the arrangement of the magic tape, namely the magic tape is installed on the inner wall of the original dust removal cover, and then the dust removal cloth bag is bonded with the magic tape.
When the magic tape is used for installation, when the dust removal cloth bag is required to be replaced and pulled down, dust on the cloth bag can generate the phenomenon of dust raising, and after the replacement, the table board of a laboratory needs to be cleaned.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a rational in infrastructure simple, the practicality is strong, is convenient for change the repeatedly usable's of dust removal sack exhaust treatment device.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a reusable waste gas treatment device comprises a dust hood and a dust removal cloth bag arranged in the dust hood, wherein the cloth bag is detachably connected with the dust hood, the dust hood is cylindrical and provided with a hollow cavity, the dust hood is detachably connected with a cover cap, two rings of annular grooves are arranged on the port of the upper edge of the dust hood, namely a first annular groove and a second annular groove, a pressing ring is detachably connected to the first annular groove, and the edge of the dust removal cloth bag is pressed and fixed by the pressing ring after being plugged into the first annular groove;
the bottom of the cover cap extends into the second annular groove to be connected with the second annular groove.
The utility model discloses further set up to: a plurality of positioning holes are formed in the lower edge port of the dust hood, and supporting pieces are detachably connected to the positioning holes.
The utility model discloses further set up to: the support piece comprises a rod body and a foot part, and the diameter of the foot part is larger than that of the rod body.
The utility model discloses further set up to: the inner wall of the first annular groove is embedded with a magnetic block, and the pressing ring has magnetism.
Contrast prior art not enough, the beneficial effects of the utility model are that:
the traditional dust hood is changed into a cylindrical shape, the dust hood is pressed into the annular groove in the dust hood, and then the dust hood is fixed on the dust hood through the pressing ring, so that the assembly and disassembly are facilitated, particularly, when the dust hood is disassembled, the dust hood can be taken down only by taking down the pressing ring, and the dust raising condition is avoided.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the dust excluding hood of the present invention.
The dust removing device comprises a dust removing cover 1, a dust removing cloth bag 2, a cover cap 3, a first annular groove 11, a second annular groove 12, a magnetic block 4, a pressing ring 5, a screw 6, a positioning hole 10, a supporting piece 7, a rod part 71 and a foot part 72.
Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 2.
The embodiment has the following specific structure: comprises a dust hood 1 and a dust removal cloth bag 2 arranged in the dust hood 1, wherein the cloth bag is detachably connected with the dust hood 1.
The dust excluding hood 1 is in a cylindrical shape and is provided with a hollow cavity, the dust excluding hood 1 is detachably connected with a hood cover 3, and the hood cover 3 is provided with a connecting port for connecting with a dust collector.
Two circles of annular grooves are arranged on the port of the upper edge of the dust hood 1, a first annular groove 11 and a second annular groove 12 are respectively arranged from the center to the outside,
the magnet 4 is embedded in the inner wall of the first annular groove 11, the edge of the dust removal cloth bag 2 is pressed and fixed by the pressing ring 5 after being plugged into the first annular groove 11, and the pressing ring 5 has magnetism. The installation stability of the dust removal cloth bag 2 is further improved through the magnetic relation between the pressing ring 5 and the magnetic block 4.
The peripheral wall of the dust hood 1 is provided with a connecting hole communicated with the second annular groove 12, and after the bottom of the cover cap 3 extends into the second annular groove 12, the cover cap 3 is fixed on the dust hood 1 through the connecting hole by a screw 6.
A plurality of positioning holes are formed in the lower edge port of the dust hood 1, and supporting pieces 7 are detachably connected to the positioning holes. The support 7 comprises a rod 71 and a foot 72, the foot having a diameter larger than the rod.
The purpose of the cooperation of the support 7 and the positioning hole: when operating on a laboratory bench, the height of the dust hood 1 is raised by inserting the support 7, the hood 3 is directly covered above a crucible, for example, and the waste gas discharged from the crucible is treated.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
