Description

Technical Field

[0001] This utility model relates to the technical field of rotary jet agitators for oil storage tanks, and in particular to a rotary jet agitator for petroleum oil storage tanks. Background Technology

[0002] In numerous industries such as petrochemicals, food and beverage, and environmental protection, stirring is a crucial step in achieving material mixing, reaction promotion, and heat and mass transfer. Currently, various types of stirrers are available on the market, such as paddle stirrers, turbine stirrers, anchor stirrers, and side-entry stirrers. However, these traditional stirrers have some limitations in practical applications. For example, paddle stirrers are mainly suitable for mixing low-viscosity liquids; their stirring effect is poor for high-viscosity media or scenarios requiring intense stirring. While turbine stirrers can generate strong shear forces, they are prone to clogging and wear when handling media containing solid particles or easily settling media. Anchor stirrers are mainly used for stirring high-viscosity liquids, but their cleaning effect on the bottom of containers is limited. These traditional stirrers rely on motor drives, which presents numerous problems such as electrical safety hazards, easy oil seal leakage, and short service life. Utility Model Content

[0024] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0025] according to Figure 1-5As shown, a rotary jet agitator for petroleum oil storage tanks includes an agitator base 1, which is an annular structure. A housing 2 is rotatably mounted on the agitator base 1 and is coaxially arranged with the agitator base 1. A nozzle 3 is fixedly mounted on the side of the housing 2 and communicates with the interior of the housing 2. The nozzle 3 is eccentrically arranged on the housing 2. A drive mechanism is provided inside the housing 2. The drive mechanism includes a turbine sealing sleeve 4, which is fixedly located at the center of the agitator base 1. Several sets of through holes 41 are opened on the side wall of the turbine sealing sleeve 4. A drive shaft 5 is rotatably mounted inside the turbine sealing sleeve 4. A turbine assembly is fixedly mounted at the bottom end of the drive shaft 5. A gearbox 6 is fixedly mounted at the top end of the turbine sealing sleeve 4. A multi-stage planetary gear set 7 is provided inside the gearbox 6. The multi-stage planetary gear set 7 is arranged sequentially from bottom to top. The lowest-level planetary gear set 7 is fixedly connected to the drive shaft 5, and the highest-level planetary gear set 7 is fixedly connected to the housing 2.

[0026] In this embodiment, each stage of the planetary gear set 7 includes a gear disk 71, a sun gear 72 rotatably mounted at the center of the gear disk 71, and several sets of planetary gears 73 arranged circumferentially around the sun gear 72. Depending on the number of stages, 3-4 planetary gears 73 are arranged around the sun gear 72. Each set of planetary gears 73 is rotatably mounted on the gear disk 71. An internal gear ring 74 is rotatably mounted around the gear disk 71 and is fixedly mounted in the gearbox 6 by bolts. The sun gear 72 of the lower-stage planetary gear set 7 is connected to the gear disk of the upper-stage planetary gear set 7. The gearbox 6 is fixedly connected to the drive shaft 5 via a fixed connection 71. A sealing cover 8 is bolted to the top of the gearbox 6, and a drive shaft 9 is rotatably mounted at the center of the sealing cover 8. The sun gear 72 of the uppermost planetary gear set 7 is fixedly connected to the drive shaft 9. The top of the drive shaft 9 extends above the sealing cover 8, and a lock nut 10 is fixedly mounted at the end of the drive shaft 9. The lock nut 10 is fixedly mounted at the axis of the housing 2. The drive mechanism employs a multi-stage planetary gear set 7 design, establishing multiple stages of reduction gear sets according to different reduction ratios. Each stage of the gear set uses a planetary design, forming a stable rotational operation. This not only precisely controls the rotational speed of the housing 2 per revolution but also improves the service life of the gears.

[0027] In this embodiment, a gearbox support plate 11 is fixedly installed at the bottom of the gearbox 6. The gearbox support plate 11 is fixedly installed on the agitator base 1. The gearbox support plate 11 is in contact with the rotating part of the housing 2. A sliding belt 19 is installed between the gearbox support plate 11 and the housing 2. The sliding belt 19 plays a role in sealing and protecting against rotational friction. In order to ensure that oil medium cannot enter the gearbox 6, a seal 12 is installed at the top of the drive shaft 5. The seal 12 is installed at the end of the turbine sealing sleeve 4 near the gearbox 6. The seal 12 adopts a mechanical seal. The mechanical seal seals the connection between the gearbox 6 and the turbine sealing sleeve 4 to ensure that oil medium cannot enter the gearbox 6.

[0028] In this embodiment, the turbine assembly includes an impeller 13 and a guide wheel 14. Both the impeller 13 and the guide wheel 14 are fixedly mounted on the drive shaft 5. The guide wheel 14 is located on the side of the impeller 13 away from the gearbox 6. When petroleum products are transported into the housing 2, the drive shaft 5 rotates under the combined action of the guide wheel 14 and the impeller 13. The drive shaft 5 drives the planetary gear set 7 connected to it to rotate. After being transmitted by the multi-stage planetary gear set 7, the housing 2 drives the nozzle 3 to rotate, so as to realize the rotational injection of petroleum products.

[0029] In this embodiment, a spray port 21 is provided on the side wall of the shell 2, and a nozzle 3 is fixedly installed at the end of the spray port 21. The nozzle 3 is eccentric at a certain angle in both the horizontal and vertical directions. In practical applications, the appropriate eccentricity is selected according to the slope of the tank bottom plate so that the spray jet can thoroughly impact the oil at the bottom and the deposited oil, achieving all-round and no dead angles. Furthermore, the reaction force generated by the spray jet will drive the shell 2 to rotate, allowing the stirring equipment to generate the power of rotation.

[0030] To facilitate the installation and transportation of the jet mixer, several sets of lifting lugs 15 are fixedly installed on the top of the housing 2 near the edge. Preferably, there are three sets of lifting lugs 15, which are arranged in a circumferential array with the axis of the housing 2 as the center. The jet mixer is connected to the hoisting equipment through the lifting lugs 15 to facilitate the installation and transportation of the jet mixer.

[0031] In this embodiment, a connecting pipe 16 is provided below the agitator base 1. A spray sleeve flange 161 is fixedly connected to the top of the connecting pipe 16. The agitator base 1 is fixedly installed on the spray sleeve flange 161 by bolts. An oil supply pipe 17 is fixedly connected to the side of the connecting pipe 16. A support frame 18 is fixedly installed at the bottom of the connecting pipe 16. When installing the spray agitator, the support frame 18 at the bottom of the connecting pipe 16 is fixedly installed at the bottom of the oil storage tank. One end of the connecting pipe 16 is connected to the oil supply pipe 17 of the oil storage tank, and the other end is connected to the agitator base 1 through the spray sleeve flange 161. When conveying petroleum products into the oil storage tank, the petroleum products are conveyed to the shell 2 through the oil supply pipe 17 and the connecting pipe 16. The pressure of the oil products being conveyed causes the shell 2 to rotate, thereby realizing the rotational spraying of the oil products.

[0032] In use, petroleum products are transported into the jet agitator via the oil delivery pipe 17 and the connecting pipe 16. The petroleum products enter through the bottom end of the turbine sealing sleeve 4, pass through the guide wheel 14 and the impeller 13 in sequence, and then enter the housing 2 through the through hole 41 on the side wall of the turbine sealing sleeve 4. The guide wheel 14 and the impeller 13 use the pressure of the oil being transported to drive the drive shaft 5 to rotate. The drive shaft 5 drives the planetary gear set 7 connected to it to rotate. After being driven by the multi-stage planetary gear set 7, the housing 2 drives the nozzle 3 to rotate, so as to realize the rotational jetting of oil. Therefore, it is not necessary to rely on electric power to drive the jet agitator to rotate, thus eliminating the safety hazards of using electric drive.
