Technical Field

[0001] The utility model relates to the technical field of insoluble scale slag collection, in particular to a device for collecting insoluble scale slag in boiler chemical cleaning liquid. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place where fuel is burned. The boiler consists of two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives.

[0003] During the chemical cleaning process of the boiler, a large amount of cleaning liquid containing insoluble scale residues will be produced. In order to deal with the insoluble scale residues, it is usually separated by static sedimentation or filtration.

The overall structure is simple and the overall practicality is effectively improved.

[0010] Furthermore, a limiting groove slidably connected to the sliding ring plate is provided inside the collecting tank, and the connecting pipe is a hard pipe.

[0011] By adopting this technical solution, the limiting groove is set so that the sliding ring plate can be embedded in the inside of the collecting tank, thereby effectively reducing the gap at the connection, effectively improving the stability of the filtration, and making the whole more practical.

[0012] Furthermore, a sliding block is fixed on the outer surface of the sliding ring plate, a sliding groove communicating with the limiting groove is provided inside the collecting groove, and the sliding block is slidably connected to the sliding groove.

[0017] By adopting this technical solution, the sealing gasket and the sealing groove are provided, so that the sealing performance of the connection between the sealing plate and the collecting groove can be effectively improved, so that leakage is less likely to occur, making the whole more stable.

[0018] Furthermore, the detection assembly includes an angle detector, an articulated rod and a buoy, the interior of the angle detector is fixed to the articulated rod, and the side of the articulated rod away from the angle detector is fixed to the buoy.

[0019] By adopting this technical solution, the set float will drive the articulated rod to move due to the different liquid level heights of the cleaning fluid.

[0020] Furthermore, a sponge pad is fixed to the outer surface of the handle, and the bottom of the mounting block on the right side and the inner bottom wall of the collecting tank are both provided with inclined surfaces.

[0021] By adopting this technical solution, the inclined surface on the mounting block makes it convenient to insert the mounting block into the interior of the sliding ring plate at an angle.
