Description

Technical Field

[0001] The utility model relates to the technical field of steam ejectors, in particular to a steam ejector with adjustable exhaust steam temperature. Background Art

[0002] Steam ejectors (also known as steam boosters) are a type of jet technology. They transform the potential energy of high-pressure steam through a nozzle into high-speed kinetic energy, driving low-pressure steam through the ejector's mixing section for thorough mixing, deceleration, and pressure increase to meet production needs. As high-pressure steam passes through the nozzle, its cross-sectional area rapidly decreases, generating a high-speed steam flow at the nozzle. This creates a low-pressure zone at the nozzle outlet, allowing low-pressure steam to be drawn in due to the pressure differential. As the high-pressure steam expands, it simultaneously compresses the low-pressure steam, using the excess pressure of the high-pressure steam to raise its pressure. The steam then passes through a mixing chamber for thorough mixing. The mixed steam is then compressed to the required pressure through a Venturi tube before being discharged through the nozzle.

[0003] In the prior art, the nozzle of the steam ejector is prone to wear during long-term use, and thus the nozzle needs to be regularly maintained. However, the existing nozzle installation structure is relatively complex, and the operation steps are relatively cumbersome, which results in reduced maintenance efficiency. Utility Model Content

[0004] The utility model mainly provides a steam ejector with adjustable exhaust steam temperature, which is convenient for installation and maintenance and improves maintenance efficiency.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a steam ejector with adjustable exhaust steam temperature, comprising a steam ejector assembly, a filter assembly is arranged at one end of the steam ejector assembly, a mounting assembly is arranged at the other end of the steam ejector assembly, the steam ejector assembly comprises a mixing chamber, the mounting assembly comprises a butt joint and a nozzle, the butt joint is mounted at one end of the mixing chamber, a mounting groove is mounted on the outer side of the butt joint, a sealing ring is mounted on the surface of the butt joint, a connecting disk is mounted at one end of the nozzle, a mounting ring is mounted on the side of the connecting disk, the mounting ring is mounted inside the mounting groove, a fastener is mounted on the outer side of the connecting disk and the mounting groove, a card block is symmetrically mounted on the inner side of the card fastener, and the outer wall of the card fastener is connected to the connecting strip through mixing. The chamber facilitates the mixing of steam and low-pressure gas. By clamping the clamping ring inside the clamping groove, the clamping groove and the connecting disk are connected, which facilitates the installation of the nozzle. The sealing ring is installed on the surface of the butt pipe, which is beneficial to provide a sealing effect, avoids steam leakage, etc., and ensures stable steam ejection. Then, the clamping groove and the connecting disk are clamped and limited using fasteners. The clamping block is clamped inside the limiting groove opened by the connecting disk and the clamping groove, further ensuring the stability of the limiting of the clamping groove and the connecting disk. The connecting strip facilitates the connection of multiple fasteners, and the operation is convenient, which facilitates the maintenance of the nozzle, reduces the time required for maintenance, improves the convenience of operation, and thereby improves maintenance efficiency. At the same time, it reduces the production interruption time caused by equipment maintenance and improves production efficiency.

[0006] Preferably, the filter assembly includes a filter box, and multiple groups of slide grooves are symmetrically installed on the inner wall of the filter box. A stainless steel filter screen slides on the inner side of the slide groove. The side of the filter box is connected to the delivery pipe, and the steam enters the interior of the filter box through the delivery pipe. Stainless steel filter screens of multiple sizes are distributed inside the filter box, which is conducive to filtering the steam step by step, effectively removing impurities in the steam, avoiding the clogging of the equipment caused by impurities, ensuring the smooth flow of the nozzle, avoiding problems such as uneven steam injection and decreased injection speed caused by clogging, thereby extending the service life of the nozzle, and sliding the stainless steel filter screen inside the slide groove, making it convenient to clean and maintain the stainless steel filter screen.

[0007] Preferably, a sealing gasket is installed on the top of the filter box, and a slide rail is symmetrically installed on the top of the filter box.

[0008] Preferably, the other end of the mixing chamber is connected to a connecting pipe, one end of which is connected to a filter box, so that the steam reaches the mixing chamber through the connecting pipe after steam filtration is completed.

[0009] Preferably, a first valve is provided in the middle of the connecting pipe, and the bottom of the mixing chamber is connected to the suction pipe. By controlling and adjusting the opening of the first valve, it is beneficial to adjust the flow rate of the steam. When a large amount of high-temperature steam enters the steam ejector assembly, the exhaust temperature of the mixed steam will increase; conversely, reducing the steam flow rate will reduce the exhaust temperature. The suction pipe facilitates the low-pressure gas from the outside to be sucked into the mixing chamber under the action of the pressure difference and mixed inside the mixing chamber.

[0010] Preferably, a second valve is provided in the middle of the suction pipe, and the flow rate of the suction gas is conveniently controlled by controlling the second valve.
