Description

Technical Field

[0001] The utility model relates to the technical field of vacuum jet pumps, in particular to an energy-saving elevated vacuum jet pump. Background Art

[0002] A vacuum jet pump is a device that uses the kinetic energy of high-speed fluid to achieve vacuum extraction and generate vacuum. It mainly drives the fluid through the work of the pump body, and completes the vacuum process by flowing in the nozzle and diffuser. It is widely used in vacuum smelting, vacuum degassing, vacuum concentration, vacuum distillation, etc.

[0003] The publication number is CN214446149U, which provides an energy-saving elevated vacuum jet pump, including a base, a plurality of auxiliary limit rods symmetrically and equidistantly fixedly connected on both sides of the upper end surface of the base, a lifting plate is provided above the base, and the lifting plate is simultaneously slidably connected to the plurality of auxiliary limit rods, and a fixed block is fixedly connected to the middle of the end surface of the lifting plate close to the base.

[0004] The above-mentioned vacuum jet pump has the effect of preventing the position of the vacuum jet pump body from shifting when the entire device is working. When it is fixed on a high frame or equipment, it is inconvenient to adjust the fixed position due to the different spacing specifications of the reserved holes on the high frame or equipment. The docking position between the impeller chamber and the vacuum chamber is offset, which makes it inconvenient to adjust the lateral position of the pump body. In addition, the pump body generates heat when it runs for a long time, and the air flow outside the pump body is poor, which is not convenient for rapid heat dissipation. Utility Model Content

[0023] Combine Figure 1-Figure 3 , energy-saving elevated vacuum jet pump, comprising a pump body 1 and an impeller chamber 2, a fixing component 3 is installed at the bottom of the pump body 1, and a heat dissipation component 4 is installed between the impeller chamber 2 and the pump body 1.

[0024] See Figure 2 , it is further obtained that the fixed assembly 3 includes a base 5 and a slide 12, the slide 12 is installed at the bottom of the pump body 1, two guide rods 6 are fixedly installed on both sides of the base 5 near the front end, and sliders 7 are movably installed on the outside of the guide rods 6 on both sides, and fixed plates 8 are fixedly installed on the outside of the two sliders 7 and on both sides of the base 5 near the rear end, the inside of the base 5 is fixedly installed with slide rods 9 on both sides, a screw 10 is movably installed in the center of the inside of the base 5, and a turntable 11 is fixedly installed at both ends of the screw 10, and the slide 12 is movably installed on the outside of the slide rods 9 and the screw 10.

[0025] The slider 7 is sleeved on the outside of the guide rod 6 and is slidably arranged. A bolt hole is opened in the middle of the fixed plate 8. By sliding the slider 7, the distance between the two fixed plates 8 can be changed. It is suitable for installation on elevated platforms and equipment of different specifications.

[0026] The bottom of the slide 12 is sleeved on the outside of the screw 10 and is threadedly connected. The bottom of the slide 12 is sleeved on the outside of the slide rod 9 and is slidingly arranged. The screw 10 drives the slide 12 to slide and adjust the lateral position.

[0027] The pump body 1 is connected to the slide 12 by bolts. The pump body 1 is fixed on the top of the slide 12. The connection position of the liquid inlet and the liquid outlet of the impeller chamber 2 is adjusted by sliding the slide 12.

[0028] Specifically, the pump body 1 is fixed to the slide 12 by bolts, the liquid inlet and liquid outlet of the impeller chamber 2 are used to connect the tube body and the vacuum chamber respectively, and the two fixed plates 8 at the rear end are fixed to the reserved holes on the elevated frame or equipment by bolts. By sliding the slider 7, the fixed plate 8 at the front end is matched with the position of the reserved hole, and can be installed on elevated frames and equipment of different specifications. The slide 12 is driven to slide by the screw 10 to adjust the lateral position of the pump body 1.

[0029] Example 2

[0030] See Figure 3 , and on the basis of Example 1, it is further obtained that the heat dissipation assembly 4 includes a fixed cover 13, the fixed cover 13 is fixedly installed between the impeller chamber 2 and the pump body 1, a plurality of fan blades 14 are installed on the periphery of the output shaft of the pump body 1 and inside the fixed cover 13, a plurality of air inlet slots 15 are opened at the rear of the fixed cover 13, a plurality of air exhaust slots 16 are opened at the front of the fixed cover 13, and a plurality of fins 17 are installed on the outside of the pump body 1 near the rear end.

[0031] A plurality of fan blades 14 are arranged around the output shaft of the pump body 1 and are installed in a surrounding manner. The output shaft of the pump body 1 passes through the interior of the fixed cover 13 and rotates movably. The output shaft drives the fan blades 14 to rotate, thereby improving the air flow outside the pump body 1 through the fan blades 14.

[0032] The exhaust slot 16 is located between every two fins 17 , and the fins 17 are installed in a surrounding manner. The airflow generated by the rotation of the fan blades 14 is discharged through the exhaust slot 16 and takes away the heat of the pump body 1 through the fins 17 , thereby improving the heat dissipation of the pump body 1 .

[0033] Specifically, the fins 17 are used to absorb the heat of the pump body 1. The output shaft drives the impeller in the impeller chamber 2, and at the same time drives the fan blades 14 to rotate, so that the airflow generated by the rotation of the fan blades 14 is discharged through the exhaust slots 16, taking away the heat of the fins 17 and improving the heat dissipation of the pump body 1.

[0034] In actual operation, the liquid inlet and outlet of the impeller chamber 2 are connected to the tube body and the vacuum chamber respectively. When the fluid enters the vacuum chamber, the kinetic energy of the high-speed fluid is used to suck and compress the gas, so that the fluid forms a high-speed jet at the nozzle outlet;

[0035] When fixing the pump body 1 on an elevated frame or equipment, the pump body 1 is fixed to the slide 12 by bolts, and the two fixing plates 8 at the rear end are fixed to the elevated frame or equipment. By sliding the slider 7, the fixing plate 8 at the front end is aligned with the reserved holes in the elevated frame or equipment and fixed. By rotating the turntable 11, the screw 10 rotates and drives the slide 12 to slide, and the lateral position of the pump body 1 is adjusted, reducing the operation of disassembling the pump body 1;

[0036] When the pump body 1 dissipates heat during operation, the output shaft of the pump body 1 drives the impeller of the impeller chamber 2, and at the same time drives the fan blades 14 to rotate. The fins 17 absorb the heat of the pump body 1 and increase the contact area with the air. The rotation of the fan blades 14 increases the air flow outside the pump body 1. The rotation of the fan blades 14 causes the air flow to be discharged through the exhaust slots 16 and takes away the heat through the fins 17.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
