[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] This embodiment, when sampling fly ash from a boiler, pours the fly ash into a sampling pan and shakes it evenly. A cross-shaped dividing assembly is then inserted around the sampling pan to divide the fly ash into four equal parts. The fly ash at the diagonal position is then poured out. By repeating the shaking, dividing, and diagonal pouring operations, the desired fly ash sample is obtained. Furthermore, the entire operation structure is simple, making it easy for staff to complete the task quickly. Furthermore, the sampling is more representative, facilitating accurate detection and judgment of the boiler's combustion conditions, greatly improving the practicality of the entire device. Specific implementations are as follows:

[0031] like Figures 1 to 5 As shown, a cross-shrinking device for fly ash sampling includes a sampling tray 1 and a cross-shrinking assembly 2. The sampling tray 1 is square and a cross-shrinking assembly 2 is movably installed in the middle. The cross-shrinking assembly 2 includes two cross-arranged partition plates 5. Four sampling slots are formed between the two partition plates 5 and the sampling tray 1. A feeding assembly is provided at the bottom of each sampling slot. When sampling fly ash in a boiler, the fly ash is poured into the sampling tray 1 and shaken evenly. Then, the cross-shrinking assembly 2 is inserted around the sampling tray 1 to divide the fly ash into four equal parts. After that, the fly ash at the diagonal position is poured out. By repeating the operations of shaking, dividing, and pouring out diagonally, the required fly ash sample can be obtained. At the same time, the entire operating structure is simple, which is convenient for the staff to complete quickly, and the sampling is more representative, which is convenient for the staff to accurately detect and judge the boiler combustion conditions, greatly improving the practicality of the entire device.

[0032] Positioning slots 3 are formed in the middle of each of the four sides of the sampling tray 1. Two limiting side plates 6 are connected to either side of the two dividing plates 5. The thickness of the limiting side plates 6 matches the thickness of the opening of the positioning slots 3. The positioning slots 3 can limit the position of the dividing plates 5 of the cross-split assembly 2, accurately dividing them into equal parts. At the same time, the height of the positioning slots 3 is smaller than the limiting side plates 6, which can prevent fly ash from getting stuck in the positioning slots 3 while positioning.

[0033] The bottom of the sampling trough is evenly distributed with four discharge ports 7 in the middle of the bottom end of the four sampling troughs, and each discharge port 7 is provided with a discharge component. The four discharge ports 7 can be used to take out the fly ash after equal division, which brings convenience to the removal of the fly ash.

[0034] The discharge assembly includes a pull-out plate 4 and a closed bottom plate 8. A pull-out channel connected to the outer wall of the sampling tray 1 is formed horizontally in the middle of the side wall of the discharge opening 7. The closed bottom plate 8 is slidably installed in the pull-out channel, and the outward side of the closed bottom plate 8 is connected to the pull-out plate 4. Through the discharge assembly set at the bottom of the sampling tray 1, the discharge opening 7 at the bottom of the sampling tray 1 can be controlled by the pull-out plate 4 and the closed bottom plate 8. It can be used when removing fly ash from the sampling tray 1. Corresponding discharge openings 7 are set below the four areas of the sampling tray 1, which brings convenience to the removal of fly ash.

[0035] The outer surface of the closed bottom plate 8 is provided with a sealing gasket. Through the sealing gasket, the sealing performance of the closed bottom plate 8 when the feed opening 7 is closed can be improved to avoid fly ash leakage.

[0036] The outside of the sampling tray 1 is provided with a reinforcing plate 12. The reinforcing plate 12 provided on the sampling tray 1 can improve its use strength and make it less likely to break or be damaged.

[0037] The inner wall of the sampling tray 1 is provided with a wear-resistant layer 10, and the outer surface of the wear-resistant layer 10 is provided with a high-temperature resistant layer 11. The wear-resistant layer 10 and the high-temperature resistant layer 11 provided on the sampling tray 1 can improve the wear resistance and high-temperature resistance of the sampling tray.

[0038] A cross groove is formed at the bottom of the inner side of the sampling tray 1, and a triangular base 9 is provided at the bottom of each of the two partition plates 5 to match the cross groove. Through the cooperation between the cross groove and the triangular base 9, the partition plates 5 can be exactly inserted into the cross groove, thereby improving the accuracy of the installation of the cross splitter assembly 2.

[0039] The sampling tray 1 and the partition plate 5 are made of stainless steel.

[0040] The top of the partition plate 5 is connected with a handle 13. Through the handle 13, it is convenient for the staff to hold and pull the partition plate 5.

[0041] Working principle: When sampling fly ash in the boiler, pour the fly ash into the sampling tray and shake it evenly. Then, insert the cross-dividing assembly around the sampling tray to divide the fly ash into four equal parts. Then pour out the fly ash at the diagonal position. Repeat the shaking, dividing and diagonal pouring operations to obtain the required fly ash sample. At the same time, the entire operation structure is simple, which is convenient for the staff to complete quickly, and the sampling is more representative, which is convenient for the staff to accurately detect and judge the boiler combustion conditions, greatly improving the practicality of the entire device. Through the discharge assembly arranged at the bottom of the sampling tray, the discharge port at the bottom of the sampling tray can be controlled by the pull-out plate and the closed bottom plate, which can be used when removing fly ash from the sampling tray, and corresponding discharge ports are arranged under the four areas of the sampling tray, which brings convenience to the removal of fly ash. By providing a reinforcement plate on the sampling tray, its use strength can be improved, making it not easy to break and damage. By providing a wear-resistant layer and a high-temperature resistant layer on the sampling tray, the wear resistance and high-temperature resistance of the sampling tray can be improved.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
