Description

Technical Field

[0001] This utility model belongs to the field of oil tank transportation technology, specifically relating to a rotary jet for vertical cylindrical storage tanks. Background Technology

[0002] Previously, in crude oil storage tanks, heavier crude oil and other heavy components would settle to the bottom after storage. The longer the storage time, the thicker the oil sludge at the bottom of the tank would become, causing oil loss and reduced tank capacity. To solve this problem, side-wall mixers were installed, but the effect was not significant. Even after installing the mixers, a large amount of oil sludge still settled at the bottom. The tanks had to be shut down every 1-2 years for bottom cleaning, increasing cleaning costs. Moreover, the cleaned-up oil sludge was difficult to dispose of and caused environmental pollution. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary jetting device for vertical cylindrical storage tanks. This rotary jetting device for vertical cylindrical storage tanks aims to solve the technical problems of the phenomenon that heavier crude oil and other heavy components sink to the bottom after oil is stored, and the longer the storage time, the thicker the oil sludge forms at the bottom of the tank, resulting in oil loss and reduced tank capacity.

[0005] (2) Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides a rotary injector for a vertical cylindrical storage tank, including a storage tank body and a rotating component disposed in the storage tank body. The outer wall of the rotating component is fixed with multiple injection pipes in a ring array. A conveying pipe is embedded and fixed at the top of the storage tank body. A fixed seat is installed below the conveying pipe. The rotating component is rotatably mounted in the fixed seat. A blade that drives the rotating component to rotate is embedded at the top of the fixed seat. A power transmission mechanism connected to the blade is embedded between the fixed seat and the rotating component.

[0007] When using this technical solution, a rotating component is installed in the main body of the storage tank. When the oil is being transported through the delivery pipe, the power generated by the liquid flow drives the blades to rotate. During the rotation of the blades, the first rotating shaft rotates. The first rotating shaft drives the second rotating shaft to rotate through a synchronous pulley and synchronous belt. During the rotation of the second rotating shaft, the rotating component drives the rotating component to rotate through gears and a gear ring. During the rotation of the rotating component, the oil is compressed through the injection pipe and sprayed onto the inner wall of the main body of the storage tank. The rotating component rotates 360 degrees in the main body of the storage tank. Each nozzle is in a different position and corresponds to a different liquid level. The high-speed rotating nozzles spray fluid to impact the bottom of the main body of the storage tank, forming a forced circulation of the medium inside the main body of the storage tank, reducing the occurrence of oil sludge settling at the bottom.

[0008] Preferably, the top wall of the main body of the storage tank is integrally formed with an installation plate that is sleeved and fixed on the conveying pipe, and a plug is fixed on the conveying pipe by bolts.

[0009] Furthermore, a fixing pipe is welded to the bottom end of the conveying pipe, and the bottom end of the fixing pipe is fixed to the fixing seat by bolts. An equipment box is welded to the outer wall of the fixing seat.

[0010] Furthermore, the mounting base has an embedded mounting cylinder, the side wall of which is welded and fixed with a connection channel for connecting to the equipment box, and the top of the mounting cylinder is integrally formed with a fastening rod that is welded and fixed to the inner wall of the mounting base.

[0011] Furthermore, a first rotating shaft fixed to the blade is rotatably installed in the mounting cylinder, and sealed bearings connected to the fixed seat are sleeved at both ends of the rotating component, and an equipment compartment is provided between the rotating component and the fixed seat.

[0012] Furthermore, a second rotating shaft is rotatably inserted into the equipment box, and the power transmission mechanism includes a synchronous pulley fixedly sleeved on the first and second rotating shafts and a synchronous belt meshing between the two synchronous pulleys.

[0013] Furthermore, a gear ring is fixedly fitted onto the rotating component, and a gear that meshes with the gear ring is fixedly fitted onto one end of the second rotating shaft that extends into the equipment compartment.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention incorporates a rotating component within the main body of the storage tank. During oil transport, the flow of liquid in the delivery pipe generates power that drives the blades to rotate. This rotation of the blades causes the first rotating shaft to rotate, which in turn drives the second rotating shaft via a synchronous pulley and belt. The second rotating shaft, in turn, drives the rotating component to rotate via gears and a gear ring. This rotation of the rotating component compresses the oil through the injection pipe and sprays it onto the inner wall of the main body of the storage tank. The rotating component rotates 360 degrees within the main body of the storage tank, with each nozzle positioned differently to correspond to different liquid levels. The high-speed rotating nozzles eject fluid that impacts the bottom of the main body of the storage tank, creating forced circulation of the medium within the tank and reducing the likelihood of oil sludge settling at the bottom.

The gears 19 meshing with each other in the 18-phase system, and the power generated by the liquid flow during oil transportation in the delivery pipe 2, drive the blades 21 to rotate. During the rotation of the blades 21, the first rotating shaft 10 rotates.
