The waste heat energy storage device for a domestic waste incineration boiler guides flue gas into the inner cavity of a main heat exchange copper tube, heats the water in the inner cavity of the main heat exchange tank by the heat of the flue gas circulating in the inner cavity of the main heat exchange copper tube, and preheats the water in the inner cavity of the auxiliary heat exchange tank by the residual heat of the flue gas circulating in the inner cavity of the auxiliary heat exchange copper tube, and uses the heat preservation tank to insulate and store the hot water in the inner cavity of the main heat exchange tank, thereby realizing the function of storing heat in the flue gas, avoiding the problem of heat waste in the flue gas generated during the incineration of domestic waste, and improving the working quality of the waste heat energy storage device for a domestic waste incineration boiler.

A hydraulic cylinder with internal self-cleaning filtration
ActiveCN224621843URealize the filtering functionAvoid affecting normal work
This utility model provides a hydraulic cylinder with internal self-cleaning filtration, including a cylinder body, a piston rod, a mounting bracket, and a cleaning assembly. The surface of the mounting bracket is fixedly connected to one side of the cylinder body. One end of the piston rod passes through the mounting bracket and the cylinder body sequentially and extends into the interior of the cylinder body. A working piston is fixedly connected to the end of the piston rod located inside the cylinder body. A connecting support rod is fixedly connected to the surface of the mounting bracket. A mounting sleeve is fitted onto the surface of one end of the connecting support rod. A connecting rod is fixedly connected to the surface of the mounting sleeve. A return box is fixedly connected to the surface of the mounting sleeve via the connecting rod. The inner wall of the return box is concave. A return pipe is connected to the bottom of the return box. The bottom end of the return pipe is connected to the surface of the cylinder body. By setting up the cleaning assembly, the entire system achieves the function of filtering hydraulic oil, avoiding affecting the normal operation of the hydraulic cylinder and ensuring the efficiency of the hydraulic cylinder.
