Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of thermal power plants, specifically a slag sampler for thermal power plants. Background Technology
[0002] Thermal power plants generate a large amount of slag during power generation. Accurate sampling and analysis of the slag is crucial for understanding boiler combustion, assessing coal quality, and optimizing slag treatment processes. A thermal power plant slag sampler is a device specifically designed for collecting slag samples. It ensures that the samples are representative, providing a reliable basis for subsequent analysis.
[0003] Existing patent document CN217059400U discloses a thermal power plant ash removal sampler, including a connecting block. A handle is fixedly connected to the left end face of the connecting block, a motor is fixedly connected to the middle of the lower end face of the connecting block, a fixing plate is fixedly connected to the lower end face of the motor, a collecting cylinder is fixedly connected to the lower end face of the fixing plate, a feed inlet is evenly distributed on the outer side of the collecting cylinder, a storage chamber is evenly distributed inside the collecting cylinder, a drill rod is fixedly connected to the output end of the motor, and a drill bit is fixedly connected to the lower end face of the drill rod. This utility model relates to the field of ash removal sampling, and this thermal power plant ash removal sampler solves the problems of existing thermal power plant ash removal samplers being inconvenient for stratified sampling of waste ash piles and inconvenient for grasping large waste ash blocks.
[0004] However, existing ash samplers for thermal power plants have problems in use. Since the ash in thermal power plants is piled up and discharged together, and sampling is required at different depths, the sampler cannot be length-adjusted according to needs during the sampling process, and cannot perform layered sampling at the same time, resulting in poor sampling results.
[0005] To address the problems raised in the background art, those skilled in the art have proposed a slag sampler for thermal power plants. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model provides a thermal power plant ash discharge sampler, which solves the problems in the prior art where the length cannot be adjusted according to requirements during the sampling process, and where layered sampling is not possible, resulting in poor sampling results.
[0007] A slag sampler for thermal power plants includes a carrying unit and a sampling unit. The carrying unit includes an outer tube, one end of which is fixedly connected to a first pair of connecting pipes. One end of the outer tube is threadedly connected to an extension tube through the first pair of connecting pipes. One end of the extension tube is fixedly connected to a connecting sleeve. Sampling ports are provided on the outer sides of both the extension tube and the outer tube.
[0008] The sampling unit includes a sampling tube that is movably inserted through one end of the outer tube. One end of the sampling tube is fixedly connected to a second pair of connecting pipes. One end of the sampling tube is threadedly connected to a sampling inner tube through the second pair of connecting pipes. Sampling cavities are provided on the outer sides of both the sampling tube and the sampling inner tube.
[0009] Preferably, the outer threaded connection of the mating sleeve has a protrusion, one end of which has a connection port, and the connection port is threadedly connected to the mating sleeve.
[0010] Preferably, a first handle is symmetrically welded to the outer side of the outer tube, and a first handle sleeve is installed on the outer side of the first handle.
[0011] Preferably, the other end of the extension tube is provided with a first pair of interfaces, which are threadedly connected to the first pair of pipes.
[0012] Preferably, a second handle is symmetrically welded to the outside of the sampling tube, and a second handle sleeve is installed on the outside of the second handle.
[0013] Preferably, one end of the sampling inner tube is provided with a second pair of interfaces, which are threadedly connected to the second pair of connecting pipes.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. In use, according to sampling requirements, the operator connects the first and second pairs of interfaces on the extension tube and the inner sampling tube to the first and second pairs of connecting pipes at one end of the outer tube and the sampling tube, respectively. At this time, the first and second pairs of connecting pipes are threadedly connected to the first and second pairs of interfaces, thereby increasing the length of the sampler. During sampling, the operator holds the first handle on the first handle to operate the sampler, and then inserts the protrusion into the slag. The protrusion pierces the slag, and both the extension tube and the outer tube are also pierced. Once inside the slag, the worker grasps the second handle on the second handle and rotates the sampling tube and inner sampling tube to align the sampling chamber on the sampling tube and inner sampling tube with the sampling port. Then, the extension tube and outer tube are rotated to allow the slag to enter the sampling chamber through the sampling port. After that, the sampling tube and inner sampling tube are rotated to detach the sampling chamber on the sampling tube and inner sampling tube from the sampling port. At this point, the sampler can be pulled out. In this way, the length can be adjusted according to needs during the sampling process, and slag at different depths can be sampled in layers, thus improving the sampling effect.

[0024] As attached Figure 1 To be continued Figure 4 As shown:
[0025] Example 1: A slag sampler for a thermal power plant includes a support unit 1 for installing sampling components, including an outer tube 104 for insertion into the slag, one end of the outer tube 104 is fixedly connected to a first connecting pipe 110 for connecting an extension tube 101, one end of the outer tube 104 is threadedly connected to an extension tube 101 for lengthening through the first connecting pipe 110, one end of the extension tube 101 is fixedly connected to a mating sleeve 108 for installing protrusions 102, and sampling ports 103 for slag entry are opened on the outer sides of both the extension tube 101 and the outer tube 104.
[0026] Furthermore, the outer side of the mating sleeve 108 is threaded with a protrusion 102 for piercing the slag. One end of the protrusion 102 is provided with a connection port 107 for fixing on the mating sleeve 108. The connection port 107 is threadedly connected to the mating sleeve 108.
[0027] Furthermore, a first handle 105 for operating the sampler is symmetrically welded to the outer side of the outer tube 104, and a first handle sleeve 106 for anti-slip function is installed on the outer side of the first handle 105.
[0028] Furthermore, the other end of the extension tube 101 is provided with a first pair of interfaces 109 for fixing the first pair of connectors 110, and the first pair of interfaces 109 are threadedly connected to the first pair of connectors 110.
[0029] As can be seen from the above, during use, the staff connects the first pair of interfaces 109 and the second pair of interfaces 206 on the extension tube 101 and the inner sampling tube 204 to the first pair of connectors 110 and the second pair of connectors 207 at one end of the outer tube 104 and the sampling tube 201, respectively, according to the sampling requirements. At this time, the first pair of connectors 110 and the second pair of connectors 207 are threadedly connected to the first pair of interfaces 109 and the second pair of interfaces 206, thereby increasing the length of the sampler. When sampling, the staff holds the first handle 106 on the first handle 105 to operate the sampler, and then inserts the protrusion 102 into the slag. At this time, the protrusion 102 pierces the slag, and the extension tube 101 and the outer tube 104 are both inserted into the slag.
[0030] Example 2: This example is basically the same as the previous example, except that the sampling unit 2 for sampling slag includes a sampling tube 201 for sampling slag that is movably inserted through one end of the outer tube 104. One end of the sampling tube 201 is fixedly connected to a second connecting pipe 207 for connecting to the inner sampling tube 204. One end of the sampling tube 201 is threadedly connected to the inner sampling tube 204 for sampling slag through the second connecting pipe 207. Sampling chambers 205 for storing slag are opened on the outer sides of both the sampling tube 201 and the inner sampling tube 204.
[0031] Furthermore, a second handle 202 for operating the sampler is symmetrically welded to the outside of the sampling tube 201, and a second handle cover 203 for protection is installed on the outside of the second handle 202.

[0033] As can be seen from the above, the staff holds the second handle 203 on the second handle 202 and rotates the sampling tube 201 and the inner sampling tube 204 so that the sampling cavity 205 on the sampling tube 201 and the inner sampling tube 204 is aligned with the sampling port 103. Then, the extension tube 101 and the outer tube 104 are rotated so that the slag enters the sampling cavity 205 through the sampling port 103. Then, the sampling tube 201 and the inner sampling tube 204 are rotated so that the sampling cavity 205 on the sampling tube 201 and the inner sampling tube 204 is separated from the sampling port 103. At this time, the sampler can be pulled out.
