Technical Field

[0001] The invention belongs to the technical field of power plant boiler condensate sampling, and in particular relates to a boiler sampling device. Background Art

[0002] Power plant boilers, as a common thermal energy equipment, play an important role in electricity production. To ensure the safe and efficient operation of the boiler, it is necessary to regularly sample and analyze various substances within the boiler, including water quality, steam, flue gas, etc. Condensate sampling is particularly important for monitoring the operating status of the boiler and changes in water quality.

[0003] However, there are some problems with the collection of condensate in existing boiler sampling technologies:

[0004] 1. Collection difficulties: The condensate in the boiler is usually in a high-temperature, high-pressure environment and is relatively dispersed, making it difficult to collect in a centralized manner. Traditional sampling methods often require manual operation, which is not only inefficient but also poses certain safety risks.

[0005] 2. Ash adhesion: During the process of collecting condensate, the collection device is easily attached to ash. Ash has a high temperature and strong adhesion. Once attached to the collection device, it will seriously affect the collection capacity of the device and lead to inaccurate sampling.

[0006] In view of the deficiencies in the prior art, the present invention provides a boiler sampling device, aiming to solve the above problems. Summary of the Invention

[0043] The sampling mechanism 4 includes a sampling platform 41, a sponge 42, and a sampling bucket 46. The sampling platform 41 is placed on the ground via a support assembly, and a drain hole 411 is provided on the platform. The sponge 42 is positioned above the drain hole 411 of the sampling platform 41 and below the outlet of the steam duct 2. The sampling bucket 46 is positioned below the drain hole 411. After absorbing condensed water from the steam duct 2, the sponge 42 directs the condensed water into the sampling bucket 46 via a squeezing assembly.

[0044] The shaking mechanism 5 is provided on the sampling platform 41 and is used to beat the side of the sponge 42 to make it vibrate.

[0045] Specifically, in this embodiment, the extrusion assembly includes:

[0046] a limit block 43 , the limit block 43 being provided on the sampling platform 41 and having one end abutting against the first side portion of the sponge 42 ; a slide rail 431 being connected to the bottom end of the side portion where the limit block 43 abuts against the sponge 42 ;

[0047] An extrusion block 44 is disposed on the sampling platform 41, and one end of the extrusion block 44 abuts against a second side portion of the sponge 42 opposite to the first side portion. A slider 441 is connected to the bottom end of the side of the extrusion block 44 abutting against the sponge 42, and the slider 441 is slidably connected to the slide rail 431.

[0048] And a cylinder 1 45 , which is arranged on the sampling platform 41 , and an output end of which is connected to the extrusion block 44 , and a movement direction of the output end of the cylinder 1 45 is consistent with a movement direction of the extrusion block 44 .

[0049] It should be noted that, in this embodiment, the support assembly includes at least three support columns 49 .

[0050] Preferably, in order to improve the accuracy of the device, in this embodiment, the sponge 42 , the water drop hole 411 and the sampling bucket 46 are located in the same vertical direction, and the size of the water drop hole 411 is larger than that of the sponge 42 .

[0051] In order to avoid burns and facilitate sample transportation, in this embodiment, at least two anti-scalding handles 47 are provided on the outer side of the sampling barrel 46.

[0052] In this embodiment, the present invention absorbs condensed water from the steam duct 2 through the sponge 42, and then uses the extrusion component to guide the condensed water into the sampling bucket 46, thereby achieving efficient collection of condensed water and solving the problem of difficulty in collecting condensed water in traditional methods.

[0053] Example 2

[0054] refer to Figure 3 and Figure 4 Based on the first embodiment, the shaking mechanism 5 designed by the present invention includes:

[0055] A side mounting plate 51 , the side mounting plate 51 being vertically mounted on the sampling platform 41 and having a dovetail groove 511 formed on its inner side;

[0056] Cylinder 2 52 , which is vertically mounted on the inner side of the side mounting plate 51 , and has an output direction vertically downward;

[0057] A connecting plate 54 is provided with a second dovetail protrusion 53 on one side of the connecting plate 54 , the second dovetail protrusion 53 being slidably connected to the second dovetail groove 511 . The bottom of the connecting plate 54 is connected to the output end of the second cylinder 52 via a connecting block 55 . An "S"-shaped sliding hole 541 is also provided on the connecting plate 54 .

[0058] A rotating plate 56 is rotatably connected to the side mounting plate 51 via a rotating shaft 562 , and a sliding rod 561 is provided on a side of the rotating plate 56 close to the connecting plate 54 , and the sliding rod 561 is movably connected to the "S"-shaped sliding hole 541 ;

[0059] and a connecting rod 563 , one end of which is connected to the rotating plate 56 , and the other end of which is connected to the impact block 57 .

[0060] In this embodiment, the present invention introduces a shaking mechanism 5, which drives the connecting plate 54 with an "S"-shaped sliding hole 541 to move up and down through the cylinder 2 52. The rotating plate 56 is restricted by the "S"-shaped sliding hole 541, and because the rotating plate 56 is limited to the side mounting plate 51 by the rotating shaft 562, the rotating plate 56 will swing left and right. The rotating plate 56 is connected to the impact block 57 through the connecting rod 563. Therefore, when the rotating plate 56 swings left and right, it will drive the impact block 57 to swing left and right, thereby achieving the slapping of the side of the sponge 42, which can effectively remove the furnace ash attached to the sponge 42 and solve the problem of inaccurate sampling caused by the adhesion of furnace ash.

[0065] In order to ensure that condensed water does not leak from the gap between the sponge 42 and the limiting block 43 or the extruding block 44 during the extrusion process, the size of the sponge 42 is smaller than that of the limiting block 43 and the extruding block 44 .

[0066] In this embodiment, the present invention has limiting baffles 48 slidingly connected on both sides of the limiting block 43, which can effectively prevent the sponge 42 from shifting laterally. At the same time, when the sponge 42 needs to be replaced after absorbing water and sampling, the limiting baffle 48 can be slid upward to release the sponge 42, making it easier to replace the sponge 42. This design can further improve the accuracy of sampling.

[0067] In summary, the present invention solves the problems of difficulty in collecting condensate and adhesion of ash in the prior art through the synergistic effect of the sampling mechanism 4, the extrusion assembly and the shaking mechanism 5. The sampling mechanism 4 realizes the efficient collection of condensate, the extrusion assembly ensures the accuracy and stability of sampling, and the shaking mechanism 5 effectively removes the ash, thereby improving the sampling quality. In addition, the size design of the sponge 42, the reasonable layout, and the detailed design of the anti-scalding handle 47 and the support assembly further improve the performance of the device and the safety of operation. Overall, the boiler sampling device of the present invention has the advantages of high efficiency, safety, accuracy and automatic cleaning, and can better meet the needs of boiler 1 sampling in industrial production.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
