Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a self-rotating jet stirrer. Background Art

[0002] In modern industry, various types of agitators are used to maintain uniformity and prevent sedimentation during the storage, transportation, and reaction of liquid media. However, existing agitators across various industries face challenges such as short service life, poor performance, and high maintenance costs. Therefore, determining the optimal agitator for these liquid media applications presents a technical challenge.

[0003] At present, the following problems exist in the use of agitators in various fields: 1. In the field of petroleum, crude oil and refined oil, and in the field of edible oil, crude oil and blended oil storage and transportation, currently using two methods: paddle-type mechanical agitators and circulating pump nozzles: (1) The paddle-type agitator has a stirring effect of only 85%, has a dead zone, cannot achieve a good blending effect, is expensive, and increases leakage points in the agitator shaft, with a low safety factor; (2) The circulating pump nozzle type has a short service life, is easy to wash the oil tank float, and is easy to get stuck when rotating externally. 2. In the field of urban smart water services, sewage, rainwater, sedimentation tanks and biochemical tanks: Currently using submersible pumps, which have a large dead zone and can only complete 240° stirring, have a low safety factor, and are directly connected to the water tank, with a high failure rate and a short service life. It can be seen that many agitators have a stirring dead zone and a low stirring effect. Utility Model Content

The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0023] Example:

[0024] The specific implementation process of the utility model: a self-rotating jet agitator, such as Figure 1 and Figure 2 As shown, it includes an upper shell 1 and a lower shell 4; the lower shell 4 is rotatably connected to the upper shell 1, a turbine impeller 7 is rotatably provided in the upper shell 1, and a mounting frame 9 is fixedly provided, a mounting cover 10 is fixedly provided on the mounting frame 9, a reduction gear box 11 is fixedly provided on the mounting cover 10, the reduction gear box 11 is transmission-connected to the turbine impeller 7 and the lower shell 4, and a nozzle 2 is fixedly provided on the lower shell 4.

[0025] The upper shell 1 is fixedly mounted on an external object, and the top end is connected to an external fluid supply device. When the external fluid supply device is started, the fluid will pass through the turbine impeller 7 from the top opening of the upper shell 1, then enter the lower shell 4, and then be ejected through the nozzle 2. When the fluid passes through the turbine impeller 7, it will push the turbine impeller 7 to rotate 360 ​​degrees without dead angles and stir. The turbine impeller 7 drives the lower shell 4 and the nozzle 2 to rotate through the reduction gear 11, and the nozzle 2 will rotate 360 ​​degrees without dead angles to spray the fluid.

[0026] like Figure 2 As shown, a transmission shaft 8 is fixedly mounted on the turbine impeller 7 . The transmission shaft 8 passes through the mounting cover 10 and is fixedly connected to the input shaft of the reduction gearbox 11 .

[0027] When the fluid drives the turbine impeller 7 to rotate, the turbine impeller 7 will rotate with the transmission shaft 8, and the transmission shaft 8 will drive the input shaft of the reduction box 11 to rotate together. A mechanical seal can be used between the transmission shaft 8 and the mounting cover 10.

[0028] like Figure 2 As shown, a transmission gear 12 is fixedly provided on the output shaft of the reduction gear box 11 , a rotating ring gear 13 is fixedly provided in the lower housing 4 , and the transmission gear 12 is engaged with the rotating ring gear 13 .

[0029] The output shaft of the reduction gear 11 rotates with the transmission gear 12 , the transmission gear 12 drives the rotating ring gear 13 to rotate, and the rotating ring gear 13 rotates with the lower housing 4 and the nozzle 2 .

[0030] like Figure 1-Figure 3 As shown, a rotation groove 6 is provided at the bottom end of the upper shell 1 , and a split ring 3 is rotatably provided in the rotation groove 6 , and the split ring 3 is fixedly connected to the lower shell 4 .

[0031] When the lower shell 4 rotates, the split ring 3 will rotate together with the lower shell 4, and the split ring 3 will rotate in the rotating groove 6. The rotating groove 6 is ring-shaped. The split ring 3 consists of two half rings, and a mounting hole 16 is opened on the half ring. During installation, first insert the bottom end of the upper shell 1 into the opening at the top of the lower shell 4, then put one half ring into the rotating groove 6, and then pass the bolt through the mounting hole 16 on the half ring and thread it to the top of the lower shell 4, then put the other half ring into the rotating groove 6, and then pass the bolt through the mounting hole 16 on the other half ring and thread it to the top of the lower shell 4. The bottom end of the rotating groove 6 can prevent the lower shell 4 and the split ring 3 from moving downward.

[0032] like Figure 2 As shown, an upper sealing groove is provided on the upper shell 1 , an upper sealing ring 15 is fixedly provided in the upper sealing groove, and the upper sealing ring 15 abuts against the lower shell 4 .

[0033] The upper sealing ring 15 can seal the gap between the upper shell 1 and the lower shell 4 to prevent fluid leakage. The upper sealing ring 15 can be an O-ring.

[0034] like Figure 2 As shown, a lower sealing groove is formed on the mounting cover 10 , a lower sealing ring 14 is fixedly provided in the lower sealing groove, and the lower sealing ring 14 abuts against the lower shell 4 .

[0035] The lower sealing ring 14 can seal the gap between the mounting cover 10 and the lower shell 4 to prevent the fluid from entering the bottom end of the lower shell 4 from the gap between the mounting cover 10 and the lower shell 4. The lower sealing ring 14 can be an O-ring.

[0036] like Figure 1 and Figure 2 As shown, a bottom cover 5 is fixedly provided at the bottom end of the lower shell 4.

[0039] The reduction box 11 is a fully enclosed reduction box 11 , which can prevent liquid from entering the reduction box 11 . Adding high-quality maintenance-free engine oil into the reduction box 11 can ensure that the reduction box 11 works stably for a long time.

[0040] like Figure 1 and Figure 2 As shown, the number of the nozzles 2 is two.

[0041] The two nozzles 2 allow the fluid to be ejected from two directions.

[0042] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
