Description
Technical field
The utility model relates to ature of coal on-line period technical field, especially a kind of new coal powder sampler.
Background technology
The coal dust of ature of coal on-line monitoring system takes from pulverized coal channel, and the coal dust in pulverized coal channel is in the drive current downflow of Bottomhole pressure air.For automatic industrial analysis instrument, the coal dust sample size of measurement is each about 100mg, also will put it in the porcelain boat of burner after taking out coal dust.In order to make got coal sample representative, therefore sample tap is selected to carry out in pulverized coal channel.The existing coal fines sampling apparatus being positioned at primary wind and powder pipeline is stretched into by sampling head in pulverized coal channel to carry out constant speed sampling, obtains coal sample after sampling after wind powder is separated.But easily blocking, needs high temperature air to carry out blowback in sampling head, and condition is harsh, cannot automatic operation for a long time.Concrete weak point is: (1) cannot realize the quantitative fetching of coal dust; (2) sampling head is goed deep into pulverized coal channel, long-term work can have wearing and tearing to sampling head; (3) sample after sampling is generally directly that sample is in a huddle, cannot realize coal dust and be laid on porcelain boat; (4) do not have corresponding emergency safety protective device, safety coefficient is not high; (5) mostly need manual operation, automatic high frequency time serial sampling cannot be realized.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of new coal powder sampler, utilize the specific mechanical mechanism of Single-chip Controlling, whole sampling process can be carried out continuously and automatically, discharged the impact of human factor, make whole sampling have more representativeness.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of new coal powder sampler, comprises the electromagnetic valve be located at outside pulverized coal channel, the first sliding rail and the second sliding rail; Import and the powder mouth of getting be located on pulverized coal channel of electromagnetic valve are tightly connected; First sliding rail and the second sliding rail are parallel to each other and the second sliding rail is located at the inner side of the first sliding rail, first sliding rail is provided with coal dust sampling pump bowl, and the sample tap of coal dust sampling pump bowl can dock with the exit seal of electromagnetic valve; Second sliding rail and coal dust sample pump bowl and are fixedly connected with, and the outer end of the piston of coal dust sampling pump bowl is located on the second sliding rail.
Further, the end of described first sliding rail is provided with the electric winch of the piston movement on its place sliding rail respectively driving coal dust sampling pump bowl and coal dust sampling pump bowl.
Further, the sample tap of described coal dust sampling pump bowl is rectangle.
Further, the front portion of described electromagnetic valve is equipped with and is only fired valve, and only combustion valve is also contained in getting on powder mouth on pulverized coal channel.
The beneficial effect adopting technique scheme to produce is:
(1) sample position is positioned at primary air inlet, and whole device runs when not having under manual intervention; Utilizing in pulverized coal channel is the feature of malleation, and coal dust sampling pump bowl of the present utility model adopts the mode of syringe-like, is taken out by coal dust from primary wind and powder pipeline, and evenly, sample is representative in sampling; (2) utilize the volume of the every sub-sampling of how many controls of coal-air ratio in pulverized coal channel, the quantitative extraction of coal dust can be realized, avoid waste; And after sampling sample can be realized evenly to be laid on porcelain boat, be conducive to the after-flame of sample; (3) installed additional before electromagnetic valve and only fired valve, considerably increased the safety coefficient of whole sampler; Stable, can run continuously for a long time; (4) sample tap of coal dust sampling pump bowl is rectangle, and for the optimal design that magnetic boat carries out, coal dust can uniform fold on magnetic boat, and what be conducive to burning is abundant.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, pulverized coal channel, 2, electromagnetic valve, 3, coal dust sampling pump bowl, the 4, first sliding rail, the 5, second sliding rail, 6, piston, 7, electric winch.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model discloses a kind of new coal powder sampler, comprise and be located at electromagnetic valve 2, first sliding rail 4 outside pulverized coal channel 1 and the second sliding rail 5; Import and the powder mouth of getting be located on pulverized coal channel 1 of electromagnetic valve 2 are tightly connected; The front portion of electromagnetic valve 2 is equipped with and is only fired valve, and only combustion valve is also contained in getting on powder mouth on pulverized coal channel 1.First sliding rail 4 and the second sliding rail 5 are parallel to each other and the second sliding rail 5 is located at the inner side of the first sliding rail 4, first sliding rail 4 is provided with coal dust sampling pump bowl 3, and the sample tap of coal dust sampling pump bowl 3 can dock with the exit seal of electromagnetic valve 2; Second sliding rail 5 and coal dust sample pump bowl 3 and are fixedly connected with, and the outer end of the piston 6 of coal dust sampling pump bowl 3 is located on the second sliding rail 5.The sample tap of coal dust sampling pump bowl 3 is rectangle.The end of the first sliding rail 4 is provided with the electric winch 7 of piston 6 movement on its place sliding rail 4,5 respectively driving coal dust sampling pump bowl 3 and coal dust sampling pump bowl 3.
In Fig. 1, coal dust sampling pump bowl 3 can move back and forth under the drive of electric winch 7 on the first sliding rail 4, the piston 6 of simultaneously coal dust sampling pump bowl 3 can move back and forth under the drive of electric winch 7 on the second sliding rail 5, and two groups of such sliding rails can realize self-movement and and the free movement of piston 6 of coal dust sampling pump bowl 3.
The course of work that the utility model gets coal dust is: coal dust sampling pump bowl 3 moves to pulverized coal channel 1 on the first sliding rail 4, until the outlet closed butt joint of getting powder mouth and electrically operated valve 2 on the coal dust sampling sample tap of pump bowl 3 and pulverized coal channel 1, electrically operated valve 2 is opened, coal dust sampling pump bowl 3 is communicated with pulverized coal channel 1, piston 6 outwards movement under driven by motor of coal dust sampling pump bowl 3, appropriate flowing coal dust is extracted out from pulverized coal channel 1, close electrically operated valve 2, coal dust sampling pump bowl 3 to be moved to above porcelain boat and to be aimed at porcelain boat, promote piston 6 coal dust in coal dust sampling pump bowl 3 is pushed in beneath porcelain boat.In order to coal dust can better be allowed to realize the tiling in porcelain boat, so that better burn, the sample tap of coal dust sampling pump bowl 3 is designed to rectangle.
In addition, only fire valve getting to have installed additional on powder mouth and in the front portion of electromagnetic valve 2, sample the electrostatic etc. that pump bowl 3 may cause to avoid coal dust and harmful effect is caused to pulverized coal channel 1, efficiently avoid the danger of pulverized coal channel blast.
The utility model is fully automatic operation under the control of microcomputer, without the need to any manual intervention, can sample with very high frequency, can meet the actual demand in industry completely.
