Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a slag sampler for a thermal power plant. Background Art

[0002] Thermal power plants generally generate heat by burning coal and then convert the heat into electricity, so this requires a large amount of coal materials. Due to the large demand for coal, once it is wasted, it will cause certain losses to the thermal power plant. The slag sampling device is a device used to sample the waste slag discharged from the power plant. It can quickly extract the waste slag discharged by power generation and is convenient for sampling. By sampling the slag and then inspecting the discharged waste slag, it can be known whether the waste slag discharged by the power plant meets the emission standards.

[0003] According to the patent with application number 202120322852.8, a slag sampler for a thermal power plant is disclosed, including a box body, a rotating rod is movably connected to the top of the left side of the inner cavity of the box body through a bearing, the left end of the rotating rod is fixedly connected to a first hand wheel, a cross tube is penetrated through the top of the right side of the box body, a conveying rod is provided in the inner cavity of the cross tube, the left end of the conveying rod is fixedly connected to the right end of the rotating rod, and the right end of the conveying rod is fixedly connected to a crushing tooth, a through groove is opened on the right side of the box body, a sealing plate is provided in the inner cavity of the through groove, a fixing plate is fixedly connected to the right side of the sealing plate, a threaded hole is opened on the right side of the box body, through holes are opened at the top and bottom of the right side of the fixing plate, a threaded rod is provided in the inner cavity of the through hole, the threaded end of the threaded rod is threadedly connected to the inner wall of the threaded hole, and the right end of the threaded rod is fixedly connected to a second hand wheel.

[0004] The above scheme solves the problem that most slag samplers in thermal power plants do not have a sealing function, cannot effectively protect the samples after sampling, easily lead to sample contamination, and cannot meet the current market demand. When collecting samples, the above scheme unscrews the screws to pull out the sealing plate and let the samples fall into the box, but this operation is too cumbersome and time-consuming and labor-intensive, and the samples cannot be collected quickly, thereby wasting time and labor costs, and there are certain shortcomings. To this end, we provide a thermal power plant slag sampler to solve the above problems. Utility Model Content

[0023] The collecting mechanism 9 comprises a first rectangular tube 901 installed on the right side of the box body 1 , and a first motor 902 is installed on the front side of the first rectangular tube 901 .

[0024] A screw rod 903 is installed at the output end of the first motor 902 , and the outer surface of the screw rod 903 is rotatably connected to the inside of the first rectangular tube 901 .

[0025] The outer surface of the screw rod 903 is threadedly connected with a slider 904 , and the outer surface of the slider 904 is slidably connected to the inner wall of the first rectangular tube 901 .

[0026] The left side surface of the slider 904 is slidably connected to the outer surface of the box body 1 , and the left side surface of the slider 904 is fixedly connected to a sealing plate 905 .

[0027] The outer surface of the sealing plate 905 is slidably connected to the interior of the box body 1 , and the upper surface of the sealing plate 905 is in contact with the outer surface of the scraper 10 .

[0028] By starting the second motor 13, the second motor 13 drives the rotating rod 14 to rotate, and the rotating rod 14 simultaneously drives the ball 15 and the crushing nail 16 to rotate, so that the slag can be crushed.

[0029] By starting the first motor 902, the first motor 902 drives the screw rod 903 to rotate, and the rotation of the screw rod 903 drives the slider 904 to move backward, and the slider 904 simultaneously drives the sealing plate 905 to move backward. During the process of the sealing plate 905 moving backward, the scraper 10 is set to block the slag discharge and scrape the slag discharge into the collecting box 4, and then repeat the above operation to move the sealing plate 905 into the box body 1.

[0030] By setting the spring 18, when the upper and lower angles of the slag pile are relatively uneven, the second sampling sliding shell 8 can be contracted, so that the sampler has strong adaptability when sampling. The specific working principle is as follows: when the second sampling sliding shell 8 contacts the slag pile, the second sampling sliding shell 8 will drive the second connecting plate 20 to move backward, and the second connecting plate 20 drives the spring 18 to contract, so that it can contract according to the flatness of the slag pile. There are two springs 18, T-shaped round rods 19, and second connecting plates 20, which are all arranged on the outer surfaces of the first sampling sliding shell 7 and the second sampling sliding shell 8 in a symmetrical state. A magnet is installed inside the box body 1, and an iron plate is installed on one side of the collecting box 4, which can be adsorbed by the magnet, thereby ensuring that the collecting box 4 and the box body 1 will not fall off during operation.

[0031] Working principle: When the utility model is in use, first hold the first handle 2 and the second handle 3, then take the sampler to the place where sampling is required, and then start the second motor 13, the second motor 13 drives the rotating rod 14 to rotate, and the rotating rod 14 synchronously drives the ball 15 and the crushing nail 16 to rotate, so that the slag can be broken, and the broken slag will fall into the second sampling sliding shell 8 and the first sampling sliding shell 7, and fall on the sealing plate 905 along the inclination of the second sampling sliding shell 8 and the first sampling sliding shell 7, and then start the first motor 902, the first motor 902 drives the wire The rod 903 rotates, and the screw rod 903 rotates to drive the slider 904 to move backward. The slider 904 simultaneously drives the sealing plate 905 to move backward. During the backward movement of the sealing plate 905, the scraper 10 is provided to block the slag discharge and scrape the slag discharge into the collecting box 4. Then, the above operation is repeated to move the sealing plate 905 into the box body 1. This allows the sampler to collect samples quickly, and solves the problem that the operation of removing the sealing plate by unscrewing the screws is too cumbersome, time-consuming and labor-intensive. At the same time, it saves time and labor costs, thereby ensuring sampling efficiency.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
