The utility model discloses simple structure, the operation of being convenient for utilizes ash pipe slant and ash grain hybrid tube lateral wall to communicate with each other to and being connected of spray tube in intake pipe and the ash grain hybrid tube, guaranteed the intensity of formation negative pressure in the pipeline, the misce bene degree of dust has been guaranteed to ash grain hybrid tube.
Description
Technical field
The utility model relates to one and adds apparatus for ash, and specifically a kind of air filter testing table adds apparatus for ash.
Background technology
Add apparatus for ash when testing for air filter filtering efficiency, the air of simulation containing impurity.The degree of accuracy of test depends on the Homogeneous phase mixing degree of impurity in air.In prior art, the structure for mixing air is more complicated, is unfavorable for the raising of test efficiency, also has the defect that mixing is uneven simultaneously.In order to solve the problem, now provide a kind of new technical scheme.
Utility model content
The purpose of this utility model is to provide a kind of air filter testing table to add apparatus for ash.
The purpose of this utility model can be achieved through the following technical solutions:
Air filter testing table adds apparatus for ash, comprises and adds grey device and grey room, and described ash indoor are equipped with air filter assembly; Ash room sidewall is provided with air intake opening, and diapire is provided with the gas outlet be connected with piezometric tube; The described grey device that adds comprises draft tube, ash inlet tube and is positioned at the jet pipe of soot particle mixing tube, and ash inlet tube one end is oblique to communicate with soot particle mixing tube sidewall; Draft tube by adapter sleeve access soot particle mixing tube one end, and is connected with jet pipe; Described ash inlet tube and soot particle mixing tube, draft tube are that 30 degree of angles are arranged.
O-ring seal is provided with between described draft tube and adapter sleeve; The nozzle place of described jet pipe is provided with shower nozzle and nylon adapter sleeve.
The beneficial effects of the utility model: the utility model structure is simple, convenient operation, utilize that ash inlet tube is oblique to communicate with soot particle mixing tube sidewall, and the connection of draft tube and soot particle mixing tube inner nozzle, ensure that the intensity of formation negative pressure in pipeline; Soot particle mixing tube ensure that the mixing uniformity of dust.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model adds grey device schematic diagram;
Fig. 3 is " A " place enlarged diagram in the utility model Fig. 2;
Fig. 4 is that the utility model adds grey schematic diagram.
Embodiment
As Fig. 1, air filter testing table adds apparatus for ash, and comprise and add grey device 4 and grey room 3, grey room 3 is built-in with air filter assembly 2, and grey room 3 sidewall is provided with air intake opening 5, and diapire is provided with the gas outlet 6 be connected with piezometric tube 1, air intake opening 5 with add grey device 4 and be connected.As Fig. 2; add grey device 4 to comprise draft tube 9, ash inlet tube 7 and be positioned at the jet pipe 11 of soot particle mixing tube 8; ash inlet tube 7 one end is oblique to communicate with soot particle mixing tube 8 sidewall, and ash inlet tube 7 is arranged in 30 degree of angles with soot particle mixing tube 8, draft tube 9, ensure that the intensity forming negative pressure in pipeline.Draft tube 9 accesses soot particle mixing tube 8 one end by adapter sleeve 10; O-ring seal 12 is provided with between draft tube 9 and adapter sleeve 10; jet pipe 11 one end is connected with draft tube 9; other end nozzle place is provided with shower nozzle 13 and nylon adapter sleeve 14; ensure that compressed-air actuated annoyance level, the setting of nozzle ensure that mixing of dust.
Ash room is according to the size design of air filter assembly.Add grey device 4 pairs of air intake openings 5 and spray dust, dust, by air-flow inspiration ash room, enters in air filter.Adding grey device is the negative pressure formed in pipeline by pressurized air, is drawn in soot particle mixing tube 8, is injected to ash indoor with pressurized air by the dust on defeated ash band 16, thus realizes automatically adding ash to air filter.The dust that defeated ash is brought is added by funnel, and funnel is arranged on weighing apparatus, can measure the quality adding ash in real time.By regulating the running speed of defeated ash band, the speed adding ash can be regulated.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
