4results about How to "Improve ejection effect" patented technology

The utility model discloses a fuel gas ejector and a burner, the fuel gas ejector comprises an ejector main body, a fuel gas inlet, a fuel gas outlet, a fuel gas inlet and a fuel gas outlet, the ejector main body is internally provided with a fuel gas channel in a penetrating manner; and the air injection guide piece is arranged at one end of the ejector main body, and the diameter of the air injection guide piece is gradually reduced in the direction away from the ejector main body. According to the fuel gas ejector provided by the utility model, when the fuel gas ejector ejects fuel gas, as the diameter of the air ejection guide piece is gradually reduced, compared with an air ejection guide piece with the same diameter, the fuel gas ejection speed is higher, more air is ejected, and the primary air ejection capability is better; the fuel gas ejector can guarantee the fuel gas ejection speed to the maximum extent and improve the air ejection capacity to the maximum extent, has positive and obvious effects on the combustion working condition and the heat efficiency index, and is simple in overall structure.

This invention relates to the field of ultrasonic cleaning technology, and more particularly to an ultrasonic cleaning device with a wastewater filtration mechanism. The device includes a cleaning tank and a drain pipe disposed at the bottom of the cleaning tank. A filter device is coaxially and detachably inserted into the inlet of the drain pipe, with an annular gap between the outer periphery of the filter device and the inner surface of the drain pipe. The filter device includes a reducing pipe, a bottom pipe, a limiting ring, a base plate, a rotating rod, and a cleaning brush. The reducing pipe includes at least one set of positive and negative conical meshes, which are coaxially and fixedly connected. The bottom pipe is coaxially fixed to the bottom end of the reducing pipe. The limiting ring seals the top of the gap, allowing wastewater from the cleaning tank to flow into the drain pipe through the reducing pipe and the gap. This invention allows residues to be removed more quickly and thoroughly from the inner circumferential surfaces of the positive and negative conical meshes.

This application discloses a high-low pressure steam mixing heat pump, including a pump body. The pump body has an inlet chamber, a mixing chamber, and a diffusion chamber. The inlet chamber includes a high-pressure inlet chamber and a low-pressure inlet chamber, through which high-pressure steam and low-pressure steam are respectively introduced. A nozzle is opened at the end of the inlet chamber, which is connected to the mixing chamber. The high-pressure steam and low-pressure steam are mixed in the mixing chamber. The mixing chamber is connected to the diffusion chamber, and a diffusion port is opened at the end of the diffusion chamber, which is connected to the outside of the pump body. After the high-pressure steam and low-pressure steam are mixed, they enter the diffusion chamber and are ejected from the pump body through the diffusion port. The application also includes a valve, which includes a plug located in the pump body and movably disposed at the nozzle of the inlet chamber. The flow rate of the high-pressure steam and low-pressure steam ejected from the nozzle is controlled by moving the plug. The high-low pressure steam mixing heat pump designed in this scheme ensures effective mixing of high and low pressure steam and improves the ejection effect of heat pump steam by setting a valve at the connection between the high-low pressure inlet chamber and the mixing chamber and controlling the high and low pressure steam entering the mixing chamber through the plug of the valve.

The application discloses a steam ejector and an ejecting method, and belongs to the technical field of steam ejectors. The steam ejector comprises, from left to right, a receiving chamber, a mixing chamber and a diffuser chamber which are sequentially connected; the receiving chamber is provided with a nozzle at an inlet end; a fluid channel is arranged below the receiving chamber; the mixing chamber comprises a converging section and a throat section connected to a right end of the converging section; the converging section is in a hollow cylindrical shape; a drainage groove is arranged below an inlet end of the converging section, and the drainage groove is used for storing condensate generated due to phase change during movement of steam; a drainage hole is arranged below the drainage groove; an adjusting assembly is matched with the drainage hole, and the adjusting assembly is used for discharging the condensate accumulated in the drainage groove. The steam ejector can effectively solve the problem that the entraining performance is reduced due to accumulated liquid at an inlet of a mixing chamber of an existing steam ejector.
