Online sand removal rotary nozzle for electro-dehydration

Abstract

This utility model relates to the field of crude oil dehydration technology, particularly to an online desanding rotary nozzle for electro-dehydration. It includes an electro-dehydration tank, a first motor fixedly connected to one side of the tank, a rotary nozzle rotatably connected inside the tank, a bracket fixedly connected to one side of the tank, and a second motor fixedly connected to one side of the bracket. A threaded rod is fixedly connected to the output end of the second motor. The advantages of this utility model are: when flushing is required, the second motor is started, driving the threaded rod to rotate. With the cooperation of the threaded hole, this drives the moving frame and water supply pipe to move outwards from the electro-dehydration tank, causing the water supply pipe to be pulled out of the rotary nozzle. Then, the first motor is started, driving the rotary nozzle to rotate. Water is then supplied through the water supply pipe into the rotary nozzle, and the water flow washes the inner wall of the electro-dehydration tank through the spray holes. Because the position of the spray pipe constantly rotates and changes, it effectively reduces blind spots during flushing.

Description

Technical Field

[0001] This utility model relates to the field of crude oil dehydration technology, and in particular to an online sand removal rotary nozzle for electro-dehydration. Background Technology

[0002] Crude oil extracted from oil fields contains a lot of water and impurities such as silt. The crude oil pretreatment process in oil fields includes a crude oil electrostatic desalting and dehydration device. During the crude oil processing, a lot of silt is deposited at the bottom of the tank. Depending on the actual operation of the electrostatic desalting and dehydration device, it needs to be flushed and drained every once in a while.

[0003] Currently, the backwashing devices designed inside electrostatic dehydration and desalination tanks generally employ two rows of flushing pipes at the bottom of the tank, with nozzles on these pipes. The nozzles are oriented tangentially to the tank body to flush away sediment. However, based on the periodic maintenance of electrostatic dehydration and desalination equipment, this backwashing system is not ideal. Because the nozzles are tangentially to the tank body, the water sprayed from the nozzles forms a non-dispersive water flow, resulting in a very small flushing area. It can only wash away sediment in the direction in which the nozzles are sprayed.

[0004] To address this issue, this utility model proposes an online sand removal rotary nozzle for electro-dehydration. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose an online sand removal rotary nozzle for electro-dehydration, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of the present invention provides an online sand removal rotary nozzle for electro-dehydration, comprising an electro-dehydration tank, a first motor fixedly connected to one side of the electro-dehydration tank, a rotary nozzle rotatably connected inside the electro-dehydration tank, a bracket fixedly connected to one side of the electro-dehydration tank, a second motor fixedly connected to one side of the bracket, a threaded rod fixedly connected to the output end of the second motor, a movable frame threadedly connected to the outside of the threaded rod, and a water supply pipe fixedly connected to one side of the movable frame.

[0008] Preferably, in any of the above embodiments, two support legs are fixedly connected to each side of the electric dehydration tank, and a discharge port is fixedly connected to the bottom of the electric dehydration tank.

[0009] Preferably, in any of the above embodiments, a first rotating hole is provided on each side of the electric dehydration tank, the two ends of the rotating nozzle are rotatably connected to the interior of the two first rotating holes, and one side of the rotating nozzle is fixedly connected to the output end of the first motor.

[0010] Preferably, in any of the above embodiments, a plurality of water spray holes are provided around the rotating nozzle, and the plurality of water spray holes are arranged in a circumferential array.

[0011] Preferably, in any of the above embodiments, a second rotating hole is provided on each side of the bracket, and the two ends of the threaded rod are rotatably connected to the interior of the two second rotating holes.

[0012] Preferably, one side of the movable frame is fixedly connected to a protrusion, and a threaded hole is provided on one side of the protrusion.

[0013] Preferably, in any of the above embodiments, the inner surface of the threaded hole is adapted to the outer surface of the threaded rod, and the inner surface of the threaded hole is threadedly connected to the outer surface of the threaded rod.

[0014] Preferably, in any of the above embodiments, the outer diameter of the water delivery pipe is adapted to the inner diameter of the rotating nozzle, and the water delivery pipe is inserted into the interior of the rotating nozzle.

[0015] Preferably, one side of the water supply pipe is fixedly connected to a baffle, and one side of the baffle is fixedly connected to a sealing gasket, which is in contact with one side of the electric dehydration tank.

[0016] Preferably, one side of the water supply pipe is fixedly connected to a water inlet.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0018] When rinsing is required, the second motor is started to drive the threaded rod to rotate. With the cooperation of the threaded hole, it can drive the moving frame and water supply pipe to move towards the outside of the electric dehydration tank, so that the water supply pipe is pulled out of the rotating spray pipe. Then, the first motor is started to drive the rotating spray pipe to rotate, and the water source is turned on to send water into the rotating spray pipe through the water supply pipe. The water flow will rinse the inner wall of the electric dehydration tank through the spray holes. Since the position of the spray pipe is constantly rotating and changing, it can effectively reduce the rinsing dead corners. In the unrinsed state, the water supply pipe is inserted into the interior of the rotating spray pipe and blocks the spray holes on the rotating spray pipe to avoid clogging of the spray holes and does not affect the electric dehydration operation.

Detailed Implementation

[0026] like Figures 1 to 4 As shown, the online sand removal rotary nozzle for electro-dehydration includes an electro-dehydration tank 1, a first motor 2 fixedly connected to one side of the electro-dehydration tank 1, a rotary nozzle 3 rotatably connected inside the electro-dehydration tank 1, a bracket 4 fixedly connected to one side of the electro-dehydration tank 1, a second motor 5 fixedly connected to one side of the bracket 4, a threaded rod 6 fixedly connected to the output end of the second motor 5, a movable frame 7 threadedly connected to the outside of the threaded rod 6, and a water supply pipe 8 fixedly connected to one side of the movable frame 7.

[0027] Two support legs 101 are fixedly connected to both sides of the electric dehydration tank 1. A discharge port 102 is fixedly connected to the bottom of the electric dehydration tank 1. After cleaning, impurities are discharged through the discharge port 102. The discharge port 102 is equipped with a valve. A feeding port is provided on the top of the electric dehydration tank 1, which is not shown in the figure.

[0028] The electric dehydration tank 1 has a first rotating hole on each side. The two ends of the rotating nozzle 3 are rotatably connected to the inside of the two first rotating holes. One side of the rotating nozzle 3 is fixedly connected to the output end of the first motor 2.

[0029] A number of water spray holes 301 are provided around the rotating nozzle 3, and the number of water spray holes 301 are arranged in a circular array.

[0030] A second rotating hole is provided on each side of the bracket 4, and the two ends of the threaded rod 6 are rotatably connected to the inside of the two second rotating holes.

[0031] A protrusion 701 is fixedly connected to one side of the movable frame 7, and a threaded hole 702 is opened on one side of the protrusion 701.

[0032] The inner surface of the threaded hole 702 is adapted to the outer surface of the threaded rod 6. The inner surface of the threaded hole 702 is threadedly connected to the outer surface of the threaded rod 6. When rinsing is required, the second motor 5 is started to drive the threaded rod 6 to rotate. With the cooperation of the threaded hole 702, the moving frame 7 and the water supply pipe 8 can be driven to move towards the outside of the electric dehydration tank 1, so that the water supply pipe 8 is pulled out of the rotating spray pipe 3. Then the first motor 2 is started to drive the rotating spray pipe 3 to rotate. Then the water source is turned on and water is supplied into the rotating spray pipe 3 through the water supply pipe 8. The water flow will rinse the inner wall of the electric dehydration tank 1 through the spray hole 301. Since the position of the spray pipe 301 is constantly rotating and changing, the rinsing dead corners can be reduced very well.

[0033] The outer diameter of the water supply pipe 8 is matched with the inner diameter of the rotating nozzle 3. The water supply pipe 8 is inserted into the interior of the rotating nozzle 3. In the unrinsed state, the water supply pipe 8 is inserted into the interior of the rotating nozzle 3 and blocks the water spray hole 301 on the rotating nozzle 3 to prevent the water spray hole 301 from being blocked and to not affect the electric dehydration operation.

[0034] A baffle 801 is fixedly connected to one side of the water supply pipe 8, and a sealing gasket 802 is fixedly connected to one side of the baffle 801. The sealing gasket 802 is in contact with one side of the electric dehydration tank 1. The sealing gasket 802 can be set so that the baffle 801 can press the sealing gasket 802 tightly against one side of the electric dehydration tank 1 when rinsing is not required, thus preventing leakage during the electric dehydration process.

[0035] A water inlet 803 is fixedly connected to one side of the water supply pipe 8. The water inlet 803 is connected to a high-pressure water source through a hose to supply water into the water supply pipe 8.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] When rinsing is required, the second motor 5 is started to drive the threaded rod 6 to rotate. With the cooperation of the threaded hole 702, the moving frame 7 and the water supply pipe 8 can be moved to the outside of the electric dehydration tank 1, so that the water supply pipe 8 is pulled out of the rotating spray pipe 3. Then the first motor 2 is started to drive the rotating spray pipe 3 to rotate. Then the water source is turned on and water is supplied into the rotating spray pipe 3 through the water supply pipe 8. The water flow will rinse the inner wall of the electric dehydration tank 1 through the spray hole 301. Since the position of the spray pipe 301 is constantly rotating and changing, the rinsing dead corners can be reduced very well. In the unrinsed state, the water supply pipe 8 is inserted into the interior of the rotating spray pipe 3 and blocks the spray hole 301 on the rotating spray pipe 3 to avoid the spray hole 301 from being blocked and to not affect the electric dehydration operation.
