Description

Technical Field

[0001] The utility model relates to the technical field of LC modules, in particular to a vortex pump capable of mixed gas and liquid transport. Background Art

[0002] A vortex pump, also known as a vortex pump or an eddy current pump, is a vane pump. Its main components include an impeller, a pump body and a pump cover. These components together form an annular flow channel. The impeller is a disk with blades on its circumference evenly arranged radially. This annular flow channel is formed between the pump body and the impeller, and the suction port and the discharge port are both located on the outer circumference of the impeller. A partition is provided between the suction port and the discharge port to isolate the two. Due to the characteristics of the vortex pump, it is usually used as a small flow, high head pump, and is particularly suitable for conveying liquids or gas-liquid mixtures with a viscosity not greater than 5E, no solid particles, and no impurities.

[0003] At present, when a vortex pump is in use, since the gap between the impeller and the pump body of a general vortex pump is narrow and the gap size is fixed, impurities may easily appear during the gas-liquid mixing process, causing blockage and affecting the delivery efficiency of the vortex pump.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-3 The present embodiment provides a vortex pump capable of mixed gas and liquid delivery, comprising a pump body 1, a pump cover 2 is installed at one end of the pump body 1 by bolts, an impeller 3 is installed at one end of the pump body 1 on the inner side of the pump cover 2, a rotating shaft 4 is installed at the center of one side of the impeller 3, the rotating shaft 4 is hexagonal, a tripod 8 is installed inside the pump cover 2, a spring 9 is installed at one end of the tripod 8, a sleeve 10 is installed at one end of the spring 9, the sleeve 10 is sleeved on the rotating shaft 4 and one end is pressed on one side of the impeller 3, when the vortex pump is performing mixed gas and liquid delivery, the gas and liquid enter the inner portion formed between the pump cover 2 and the pump body 1 , and transports gas and liquid between the impeller 3 and the pump body 1. When impurities appear and cause gas and liquid to form a blockage between the impeller 3 and the pump body 1, the gap pressure between the impeller 3 and the pump body 1 increases. At this time, the impeller 3 will squeeze the sleeve 10 under the pressure of the gas and liquid and slide on the rotating shaft 4, thereby expanding the gap between the impeller 3 and the pump body 1, thereby offsetting the pressure caused by the blockage and allowing the vortex pump to transport normally. When the vortex pump stops running, the spring 9 squeezes the sleeve 10, and the sleeve 10 pushes the impeller 3 back to its original position, thereby achieving the purpose of automatically adjusting the vortex pump to ensure the transportation efficiency when blockage occurs.

[0024] In this embodiment, if Figure 1 As shown, a feed pipe 6 is installed on the outer side of the pump cover 2, a discharge pipe 5 is installed on the top of the pump cover 2, and screws are provided at three corners of the outer side of the pump cover 2 to be threadedly connected and fixed to the pump body 1. The conveying medium enters the interior of the pump cover 2 from the feed pipe 6, and enters the gap between the impeller 3 and the pump body 1 under the rotation of the impeller 3, and finally forms a vortex under the rotation of the impeller 3 and is discharged from the discharge pipe 5.

[0025] In this embodiment, if Figure 2 and Figure 3As shown, there are hexagonal through holes at the centers of the two sides of the impeller 3 and the impeller 3 is sleeved on the outside of the rotating shaft 4. The impeller 3 can slide on the rotating shaft 4 through the hexagonal through holes. When the rotating shaft 4 rotates, the impeller 3 can be driven to rotate. At the same time, the impeller 3 can also slide on the rotating shaft 4 to adjust the gap between the impeller 3 and the pump body 1.

[0026] In this embodiment, if Figure 3 As shown, one end of the rotating shaft 4 is inserted into the interior of the sleeve 10, and when the impeller 3 is in the initial position, one end of the rotating shaft 4 fits with one end of the interior of the sleeve 10. When the vortex pump stops, the sleeve 10 squeezes the impeller 3 to slide on the rotating shaft 4 under the action of the spring 9, and under the limitation of the length of the rotating shaft 4, the sleeve 10 can just push the impeller 3 to the initial position.

[0027] In this embodiment, if Figure 1 and Figure 3 As shown, a through hole 201 is provided at the bottom of the pump cover 2, and the interior of the through hole 201 is communicated with the interior of the pump cover 2. A threaded ring is provided on the edge of the through hole 201 at the bottom of the pump cover 2, and a dust collecting barrel 7 is installed at the bottom of the pump cover 2. The dust collecting barrel 7 is threadedly connected to the threaded ring on the edge of the through hole 201. After blockage occurs inside the vortex pump, the conveying efficiency is guaranteed by adjusting the gap size. After the vortex pump stops, the impurities in the gap will slide downward and enter into the dust collecting barrel 7, thereby clearing the blockage of the vortex pump. At the same time, the dust collecting barrel 7 is easy to disassemble, thereby improving the blockage clearing efficiency of the vortex pump.

[0028] In this embodiment, if Figure 3 As shown, a sliding rod is provided at one end of the sleeve 10, and the sleeve 10 is slidably mounted on the sliding rod. At the same time, one end of the sliding rod is fixedly connected to a side surface of the tripod 8. The spring 9 is mounted on the outer ring surface of the sliding rod, and the two ends of the spring 9 are respectively fixedly connected between the tripod 8 and the sleeve 10, so that the sleeve 10 can slide stably and linearly on the sliding rod to prevent the sleeve 10 from shaking significantly when the vortex pump is started and causing abnormal noise.

[0029] Working principle: When the vortex pump is in use, the feed pipe 6 is connected to the supply end of the medium, and the discharge pipe 5 is connected to the conveying pipeline. When the vortex pump is performing gas-liquid mixed delivery, the conveying medium enters the interior of the pump cover 2 from the feed pipe 6, and enters the gap between the impeller 3 and the pump body 1 under the rotation of the impeller 3. Finally, a vortex is formed under the rotation of the impeller 3 and discharged from the discharge pipe 5. When impurities appear and cause gas and liquid to form a blockage between the impeller 3 and the pump body 1, the gap pressure between the impeller 3 and the pump body 1 increases. At this time, the impeller 3 will squeeze the sleeve 10 under the pressure of the gas and liquid and slide on the rotating shaft 4, thereby expanding The gap between the impeller 3 and the pump body 1 offsets the pressure caused by the blockage, allowing the vortex pump to deliver normally. When the vortex pump stops running, the sleeve 10 squeezes the impeller 3 to slide on the rotating shaft 4 under the action of the spring 9, and under the limitation of the length of the rotating shaft 4, the sleeve 10 can just push the impeller 3 to the initial position, so that the vortex pump can automatically adjust to ensure the delivery efficiency when blockage occurs. After the vortex pump stops, the impurities in the gap will slide downward and enter the dust collecting barrel 7, thereby clearing the blockage of the vortex pump. At the same time, the dust collecting barrel 7 is easy to disassemble, which improves the blockage clearing efficiency of the vortex pump.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
