Abstract
The utility model discloses an exhaust device for sample pretreatment, and belongs to a waste gas treatment device. The exhaust device comprises a frame and a waste gas collecting tube, wherein the waste gas collecting tube is mounted in the middle of the frame, fixed handles are arranged on two sides of the frame, the inner side of each fixed handle is provided with a moving handle, the moving handle is connected with a moving plate at the bottom of the frame via a guide rod mounted in the frame, twenty sealed members matching with digesting tubes are mounted on the frame under the waste gas collecting tube via a connecting part, the sealed members are communicated with the waste gas collecting tube via gas guide tubes inside thereof, and seal rings are mounted on the lower portions of the sealed members. Compared with the prior art, the exhaust device for sample pretreatment has the advantages of reasonable design, simple structure, easy processing, convenient operation, fine sealing effect, low pollution to samples and the like, and effectively increases experimental precision.
Description
Technical field
The utility model relates to the waste gas treatment equipment field, specifically a kind of exhaust apparatus of sample pre-treatments.
Background technology
At present the exhaust apparatus of each manufacturer 20 hole digestings of producing on the market can not guarantee to seal as much as possible fully with digest tube, and lays and to take off exhaust apparatus loaded down with trivial details.Thereby caused digestion waste gas process in a large amount of corrosive gass fly away in the air harmful to human and contaminated environment.In addition, part waste gas becomes liquid in the digestion process cooling, causes violent chemical reaction after dropping onto reaction liquid, causes certain potential safety hazard and produces strong noise, influences staff's operate as normal.
The utility model content
Technical assignment of the present utility model provides a kind of simple to operation, good sealing effect, the exhaust apparatus of the sample pre-treatments that sample contamination is few.
Technical assignment of the present utility model is realized in the following manner, this exhaust apparatus comprises support body and gas sampling pipe, the gas sampling pipe is installed in the middle part of support body, the both sides of support body are respectively arranged with quiet handle, the inboard of each quiet handle all is provided with a moving handle, and moving handle is connected with the moving plate of support body bottom by the guide rod that is installed in the support body; 20 seals that cooperate with digest tube are installed in by web member on the support body of gas sampling pipe below, and seal is communicated with the gas sampling pipe by its inner wireway, and the bottom of seal is equipped with O-ring seal.
Described gas sampling pipe one side is communicated with the waste gas gas outlet of support body side.
The seal outside surface of described O-ring seal below is conical.
The bottom surface of described seal is an inner concave arc surface.
The external diameter of described O-ring seal is greater than the internal diameter of digest tube.
The exhaust apparatus of sample pre-treatments of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, simple to operation, good sealing effect, characteristics such as sample contamination is few effectively raise the degree of accuracy of experiment.

Accompanying drawing 2 is the structural representation of seal;
Among the figure: 1, support body, 2, quiet handle, 3, moving handle, 4, the gas sampling pipe, 5, guide rod, 6, moving plate, 7, O-ring seal, 8, seal, 9, digest tube, 10, the waste gas gas outlet, 11, wireway, 12, web member, 13, cambered surface.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The exhaust apparatus of this sample pre-treatments comprises support body 1 and gas sampling pipe 4, and gas sampling pipe 4 is installed in the middle part of support body 1, and gas sampling pipe 4 one sides are communicated with the waste gas gas outlet 10 of support body 1 side; The both sides of support body 1 are respectively arranged with quiet handle 2, and the inboard of each quiet handle 2 all is provided with a moving handle 3, and moving handle 3 is connected with the moving plate 6 of support body 1 bottom by the guide rod 5 that is installed in the support body 1; 20 seals 8 that cooperate with digest tube 9 are installed on the support body 1 of gas sampling pipe 4 belows by web member 12, seal 8 is communicated with gas sampling pipe 4 by its inner wireway 11, the bottom of seal 8 is equipped with O-ring seal 7, the external diameter of O-ring seal 7 is greater than the internal diameter of digest tube 9, seal 8 outside surfaces of O-ring seal 7 belows are conical, and the bottom surface of seal 8 is an inner concave arc surface 13.
During operate as normal, 20 seals 8 that adopt poly fourfluoroplastics to make are sealed in respectively in the corresponding digest tube 9, and the waste gas that produces in the digest tube 9 enters gas sampling pipe 4 by wireway 11, discharges by waste gas gas outlet 10 then.Because O-ring seal 7 adopts anti-300 degree high temperature corrosion-resistings, the rubber manufacturing of good springiness forms, and the external diameter of O-ring seal 7 is greater than the internal diameter of digest tube 9, so sealing effectiveness is good; When waste gas attached to seal 8 lower cone shape surfaces, and the cambered surface 13 of indent is cooled off when becoming liquid, can flow to digest tube 9 inwalls along the trochoidal surface and the inner concave arc surface 13 of seal 8, finally slowly flow back to reaction liquid, cooling liquid can not occur and drop in the phenomenon that causes vigorous reaction on the reactant liquor along digest tube 9 inwalls.
When needs took off exhaust apparatus, two hands were caught quiet handle 2 respectively, and thumb is pinned on the moving handle 3 and carried, and the moving plate 6 of support body 1 bottom can block digest tube 9, makes seal 8 spin off from digest tube 9, can easily take off exhaust apparatus.
Claims (5)
1. the exhaust apparatus of sample pre-treatments, comprise support body and gas sampling pipe, the gas sampling pipe is installed in the middle part of support body, the both sides that it is characterized in that support body are respectively arranged with quiet handle, the inboard of each quiet handle all is provided with a moving handle, and moving handle is connected with the moving plate of support body bottom by the guide rod that is installed in the support body; 20 seals that cooperate with digest tube are installed in by web member on the support body of gas sampling pipe below, and seal is communicated with the gas sampling pipe by its inner wireway, and the bottom of seal is equipped with O-ring seal.
