Description

Technical Field

[0001] The utility model relates to the field of coal chemical gasification devices, in particular to a slag scraper slag flushing device. Background Art

[0002] The Texaco coal chemical gasification unit uses liquid slag removal. After the slag water enters the slag pool, the scraper's scraper removes the solid slag into the hopper, achieving solid-liquid separation. Driven by a chain, the scraper carries the solid slag upward along an inclined surface into the upper part of the hopper. After the scraper flips, the slag falls into the hopper by its own weight. After the scraper flips, the chain continues to return to the slag pool for slag removal. Before the scraper flips into the slag pool water bath, the fine slag remaining on the upper part cannot be removed by its own weight, which affects the mechanical components during operation. The K-type scraper is particularly effective in slag removal. However, its structure also results in a large amount of slag remaining on the return trip after slag removal, which is more noticeable in the operation of the slag remover. The industry's response often uses spray-type flushing water, but the concave structure of the K-type scraper often does not rinse thoroughly, leaving a large amount of residue, which does not fundamentally solve the problem. Summary of the Invention

[0003] The utility model aims to provide a slag washing device for a scraper of a slag scooping machine, so as to solve the problem that the K-type scraper of the existing slag scooping machine cannot be washed thoroughly and a large amount of coal slag still remains.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a slag scraper slag flushing device for cleaning the K-type scraper of a slag remover, characterized by comprising:

[0005] The water collecting drum is installed on the upper part where the K-type scraper passes;

[0006] The water collecting tube support base is arranged on both sides of the water collecting tube and connected to the slag scoop frame. The bottom of the water collecting tube is provided with a jet outlet.

[0007] There are two rows of jet outlets, and flushing water passes through the two rows of jet outlets to form side jet flows and a vertical water curtain flow at the bottom;

[0008] The side water jet flow is directly sprayed into the groove of the K-type scraper, and the vertical water curtain flow fully washes the K-type scraper.

[0009] Furthermore, a water inlet is provided on the water collecting cylinder, and the water collecting cylinder and the water inlet are connected by welding.

[0010] Furthermore, the water collecting cylinder and the water collecting cylinder support seat are clearance-fitted, and the water collecting cylinder can rotate radially.

[0011] Furthermore, the water collecting cylinder support seat is provided with a locking nut and a locking screw. When the angle of the water collecting cylinder is adjusted, it is fixed by the locking nut and the locking screw.

[0012] Furthermore, water collecting cylinder cleaning ports are provided on both sides of the water collecting cylinder for cleaning scale and impurities in the water collecting cylinder, and the water collecting cylinder and the water collecting cylinder cleaning ports are connected by flanges.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, this solution changes the spray-type flushing method to a jet method that combines spraying and water curtain, which is suitable for the characteristics of the K-type structure and has obvious effects. There are two jet outlets, with a 30° angle between them. The flushing water is sprayed out at a 30° angle through the two outlets, forming a side jet flow and a vertical water curtain flow at the bottom. The K-type scraper at the bottom is flushed by these two streams of water in turn. The side jet flow is directly sprayed into the groove of the K-type scraper at an angle to completely clean up the entrained residual residue. The vertical water curtain is to ensure that there are no dead angles in the cleaning. Because the scraper will swing a certain amount when passing the guide wheel during operation due to the chain. The scraper is installed on the chain, so the scraper will swing slightly with the chain. When the scraper swings, the angle of the K-type scraper will change.

[0015] Second, the water collecting tube of this solution can be radially rotated to adjust the water outlet angle, so as to adjust the flushing angle of the water jet on the K-type scraper, and the directional flushing effect on the K-type scraper is obvious.

[0016] Third, in this solution, water collection tube cleaning ports are set on both sides of the water collection tube to regularly clean the scale and impurities in the water collection tube. The water collection tube cleaning ports are flange-connected, which is easy to disassemble and maintain.

[0017] Fourth, this solution has a simple structure, low manufacturing cost and good economic applicability. BRIEF DESCRIPTION OF THE DRAWINGS
