Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a non-methane total hydrocarbon analyzer comprises an analyzer body 1, an air chamber 2 is fixedly connected to the side surface of the analyzer body 1, a motor 3 is fixedly mounted on the top surface of the air chamber 2, a filter screen 4 is fixedly connected to the inner surface of the air chamber 2, a suction fan 5 is fixedly mounted to the side surface of the air chamber 2, an air outlet end of the suction fan 5 is communicated with the air chamber 2 through an air pipe, a screw rod 6 is coupled to the tail end of an output shaft of the motor 3, and one end, away from the motor 3, of the screw rod 6 is rotatably connected with the inner bottom surface of the air chamber 2.

The ash cleaning mechanism 8 is arranged in the air chamber 2, the ash cleaning mechanism 8 comprises a rubber plate 81, a moving block 82, a rotating rod 83, a fur ring 84 and a cam 85, the moving block 82 is fixedly connected to the side surface of the rubber plate 81, the moving block 82 is sleeved on the screw rod 6 in a threaded manner, two side surfaces with the farthest relative distance of the rubber plate 81 are both attached to the inner surface of the air chamber 2, the rubber plate 81 is prevented from being driven to rotate when the screw rod 6 rotates, the rubber plate 81 can only move up and down along the screw rod 6, one end of the rotating rod 83 is rotatably connected to the side surface of the moving block 82, the fur ring 84 is fixedly sleeved on the rotating rod 83, the fur ring 84 is attached to the side surface of the rubber plate 81, the fur ring 84 can continuously rub against the rubber plate 81 in the rotating process, static electricity can be generated on the rubber plate 81, the fur ring can be conveniently adsorbed with dust, the cam 85 is fixedly sleeved on the rotating rod 83, the inner bottom surface of the air chamber 2 is provided with a detachable collecting box 7, collect box 7 and be located rubber slab 81 under, when the device is not using, the static on the rubber slab 81 can disappear gradually, and the dust of attached to on rubber slab 81 can fall into and collect box 7 in, makes things convenient for the staff later stage to unify the processing to the dust.

Be equipped with drive assembly 9 in the air chamber 2, drive assembly 9 includes gear 91 and rack 92, and the fixed cover of gear 91 is connected on bull stick 83, and the equal fixed connection in the inner face of air chamber 2 in both ends about rack 92, gear 91 and rack 92 mesh mutually, and bull stick 83 can rotate under drive assembly 9's effect when so setting up messenger rubber slab 81 reciprocated.

The in-process that analyzer body 1 was using, staff startable motor 3, motor 3 can drive lead screw 6 when moving and rotate, because the side that two relative distances of rubber slab 81 are farthest all laminates with the inner face of air chamber 2 mutually, so lead screw 6 can not drive rubber slab 81 when rotating and rotate, make rubber slab 81 can only move down along lead screw 6, the in-process that rubber slab 81 reciprocated, under the effect of rack 92, gear 91 can drive bull stick 83 and take place to rotate, thereby it takes place to rotate to drive fur collar 84 and cam 85.

Cam 85 can be periodic when rotating and filter screen 4 contacts, because filter screen 4 can take place elastic deformation usually, so cam 85 can make filter screen 4 produce vibrations when rotating to shake the dust that is attached to filter screen 4 surface, and meanwhile, fur ring 84 can be continuous when rotating and rubber sheet 81 looks mutual friction, make rubber sheet 81 surface produce a large amount of static, can play the adsorption of dust that is shaken and falls, thereby clear up and collect the dust on filter screen 4 surface.

When the device is not used, the staff accessible control motor 3 makes the rubber slab 81 remove the top of collecting the box 7, and when the bull stick 83 stall, the fur circle 84 no longer rubs with rubber slab 81 each other, and the static on the rubber slab 81 can disappear gradually, and the dust of attached to on the rubber slab 81 can fall into in collecting the box 7, makes things convenient for the staff later stage to unify the processing to the dust.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
