Description

Filter paper band conveyer

The utility model relates to a kind of filter paper band conveyer that is used for the dust measurement device.

At present, the filter paper band conveyer in the dust measuring device, a kind of is to adopt whole section filter paper is placed on the fixed mount, on the fixed position, the integral inverted reciprocating cutter, its complex structure, and make the requirement height; The another kind of employing is in the same place sampling channel and measurement system incorporates, though save the required complicated machinery driving device of filter paper transmission, needs senior measurement mechanism.Its detector vulnerable to pollution influences the service life and the survey precision of device.

The purpose of this utility model is to provide a kind of flexible mechanical filter paper band conveyer simple in structure.It will install sampling channel and measuring system separates, but long-term work is not contaminated, prolongs the service life of key element and can reach required survey precision.Improved the defective of prior art.

The purpose of this utility model is achieved in that a kind of filter paper band conveyer with the dry dust measurement mechanism, by the paper supply tep reel, the collection tep reel, driving band, compositions such as chart drive motor, it is characterized in that: cylindrical weight lays respectively in the rail brackets, each riser by two band guide-track grooves of rail brackets constitutes, the guide-track groove of rail brackets is, the guide-track groove of rail brackets is, the axle of cylindrical weight lays respectively in the guide-track groove, weight, be pressed in the filter paper band and the filter paper band is tightened, and can be with the degree of tightness of filter paper band along guide rail fine motion up and down, pressure roller and pressure roller strut bar, lift the pinch roller spanner and coexist on the adapter plate paper feed pulley, third wheel the axle with just, oppositely chart drive motor connects with driving band.

The purpose of this utility model is specific implementation as follows also: pressure roller is made of two circle wheels, is wound with stage clip on the pressure roller strut bar, and the top clinching of stage clip is at the upper limb of adapter plate.The top of stage clip is the knuckle shape.The collection motor is connected with belt with the axle of collection tep reel, and paper feeding motor is connected with belt with the axle of paper supply tep reel.

The filter paper band conveyer that adopts the utility model to provide, simple in structure, the long-time running trouble free.It is little that the filter paper band transmits frictional resistance, stressed evenly sideslip not.It can make the device long-term work not contaminated, and can reach the required survey precision that gets.Maintaining is convenient, and this installs accessible technical index and is: total dirt 0.1 to the 1000MG/M pellet of dust measuring scope 0.01 to 10MG/M smart attitude precision 2% adopts speck area 2CM zero line to measure 24 hours 95% above data less than 0.05MG/M

Below in conjunction with drawings and Examples the utility model is done further narration.

Fig. 1 is that structure master of the present utility model looks scheme drawing.

Fig. 2 is a structure schematic rear view of the present utility model.

With reference to Fig. 1, on the paper

supply tep reel

1,15 the filter paper tep reel is housed,

cylindrical weight

2,14 lays respectively in the rail brackets 23,17, rail brackets 23,17 each riser by two band guide-track grooves constitute, the guide-track groove of rail brackets 23 is 38, the guide-track groove of rail brackets 17 is 39, and the axle 37,40 of

cylindrical weight

2,14 lays respectively in the guide-track groove 38,39, and can slide in guide-track groove.Pressure roller 10 and pressure roller strut bar 13, lift pinch roller spanner 16 and coexist on the adapter plate 42 pressure roller and paper feed pulley 18 rolling touch.Be wound with stage clip 11 on the pressure roller strut bar 13, top 41 clinchings of stage clip 11 are at the upper limb of adapter plate, and the top 41 of stage clip is a knuckle shape.Pinch roller fixed block 12 is lifted in adapter plate 42 tops.

Measurement mechanism 8 has third wheel 22 on one side, in measurement mechanism, fixed cover 6 is arranged outside the gas circuit connection pipe 7, and connection pipe 7 bottoms connect pressure head 5, and pressure head bar 4 is lifted in the outside connection one of pressure head, and the pressure head bottom also has a seal ring 3.Measurement mechanism middle part has one can be by the slit 36 of filter paper band, and the measurement mechanism bottom connects gas circuit 21, and gas circuit control cock 19 and gas circuit release handle 20 are in order to regulate the air-flow size.Filter paper band 9,, is rolled onto on the collection tep reel 15 between third wheel 22, slit 36, paper feed pulley 18 and the pressure roller 10, weight 14 lower edges through weight 2 lower edges from paper supply tep reel 1.

With reference to Fig. 2, collection motor 24 is connected with belt 25 with the axle of collection tep reel 15, the below of weight 14 is equipped with a right position control orifice plate 26, control desk side, right position is equipped with a collection upper limit photoelectric switch 27 and collection lower limit photoelectric switch 28, the axle of paper feed pulley 18, third wheel 22 is connected with forward and reverse chart drive motor 30 usefulness driving bands 29, and the below of weight 2 is equipped with position, left side control orifice plate 31.Position, left side control orifice plate top is equipped with collection upper limit photoelectric switch 32 and collection lower limit photoelectric switch 33.Paper feeding motor 35 is connected with belt 34 with the axle of paper supply tep reel 1.
