Description

Technical Field

[0001] The utility model belongs to the technical field of sampling devices, in particular to a dust sampling device for a dust collector. Background Art

[0002] At present, in the electricity market environment with oversupply, the competition in the thermal power industry is becoming increasingly fierce. If thermal power plants want to survive and develop in the fierce competition, they must strengthen cost control. Power plants are generally facing great cost pressure. The actual coal burned in many power plants deviates from the designed coal type of the boiler, which has a great impact on the dust collection efficiency of the dust collector. Therefore, it is necessary to sample and analyze the coal combustion dust in real time. After searching, the patent with application number 202220732123.4 discloses a dust collector dust sampling device, including: a dust conveying pipe, a spiral vane and a dust removal pipe. The dust conveying pipe is inserted into the dust collector hopper and welded to the side wall of the dust collector hopper. The dust removal pipe is welded to the outer end of the dust conveying pipe, and a spiral vane is rotatably connected in the dust conveying pipe.

[0003] However, during actual use, the applicant found that after sampling the dust in the dust collector hopper through the dust conveying pipe and the dust collection pipe, a certain amount of dust will remain inside the dust conveying pipe and the dust collection pipe. This part of the old collected dust will cause great interference to the newly collected dust during the next real-time dust sampling, thereby reducing the results of the real-time dust sampling and analysis. In view of this, we proposed a dust sampling device for the dust collector. Utility Model Content

[0020] See also Figure 1-3 As shown, the utility model provides a technical solution:

[0021] When dust is collected by the dust collector 1, the dust collecting box 1 is fixed with a rectangular fixed seat 2, and the interior of the rectangular fixed seat 2 is slidably connected to the movable seat 3. The top of the rear end of the movable seat 3 is provided with a limiting protrusion 33, which is flush with the top of the rectangular fixed seat 2. The limiting protrusion 33 is used to limit the movement of the movable seat 3 to prevent the movable seat 3 from escaping from the rectangular fixed seat 2. The interior of the rectangular fixed seat 2 is rotatably connected to a screw 5 by a bearing. The front end of the screw 5 is screwed into the movable seat 3, and the rear end of the screw 5 extends to the outside of the rectangular fixed seat 2 and is fixedly connected to the hand crank 51. A dust sampling box 4 is placed in the movable seat 3. The dust sampling box 4 can be used to sample the dust entering the dust collector hopper 1, and by setting the dust sampling box 4 and the movable seat 3 as a detachable structure, the inner wall of the dust sampling box 4 can be cleaned after each dust sampling, thereby effectively reducing the impact of old collected dust on new collected dust. The interference caused by dust is eliminated, and real-time sampling is realized, so that the results of coal combustion dust sampling and analysis are more accurate. A sampling box placement groove 32 is provided on the top of the movable seat 3 in front of the limiting protrusion 33. The width of the sampling box placement groove 32 is the same as the width of the limiting protrusion 33. The dust sampling box 4 is placed in the sampling box placement groove 32, and the height of the dust sampling box 4 is the same as the depth of the sampling box placement groove 32. A threaded groove is provided in the movable seat 3 below the sampling box placement groove 32. 31, and the threaded groove 31 is threadedly matched with the screw rod 5, and a top groove 21 is provided on the top of the rectangular fixed seat 2 at one end outside the dust collector hopper 1, and the limiting protrusion 33 slides along the top groove 21, and the rectangular fixed seat 2 on both sides of the top groove 21 is symmetrically provided with a taking and placing side groove 22, and the bottom of the taking and placing side groove 22 is flush with the bottom of the sampling box placement groove 32, the length of the top groove 21 is the same as the length of the sampling box placement groove 32, and the width of the top groove 21 is the same as the width of the sampling box placement groove 32.

[0022] Working principle: When in use, the hand crank 51 can be manually rotated clockwise to drive the screw 5 to rotate. The rotation of the screw 5 can drive the movable seat 3 to move forward along the inner wall of the rectangular fixed seat 2. The movement of the movable seat 3 can drive the dust sampling box 4 to move forward, and make the front end of the dust sampling box 4 extend to the outside of the rectangular fixed seat 2, so that the interior of the dust sampling box 4 is connected with the interior of the dust collector hopper 1. At this time, some of the dust entering the dust collector hopper 1 can fall into the dust sampling box 4 for collection. After a period of time, the hand crank 51 can be manually rotated counterclockwise to drive the screw 5 to rotate. The rotation of the screw 5 can drive The movable seat 3 and the dust sampling box 4 move to the right, and the dust sampling box 4 is moved back to the bottom of the top slot 21. At this time, the personnel can pull out the two sides of the dust sampling box 4 from the side slots 22, take the dust sampling box 4 out of the sampling box placement groove 32 inside the movable seat 3, and lead out the dust collected in the dust sampling box 4 for sampling and analysis. After the dust inside the dust sampling box 4 is led out, the dust sampling box 4 can be cleaned as a whole, and the dust sampling box 4 can be put back from the top slot 21 to the sampling box placement groove 32, so as to realize the next real-time sampling of the dust inside the dust collector hopper 1.
