Description

Technical Field

[0001] This utility model relates to a crude oil mixer with an internally adjustable inlet size. Background Technology

[0002] Crude oil mixers are used to mix crude oil before processing, such as by mixing crude oil and demulsifiers in the crude oil mixer to facilitate subsequent crude oil processing.

[0003] In traditional crude oil mixers, a common practice to control the pressure and flow rate of the incoming crude oil is to install a separate valve device upstream of the mixer. This conventional design treats the valve as an independent, additional structure preceding the main unit, capable only of controlling the opening and closing of the feedstock to regulate its flow rate within a certain range before it enters the mixer. The drawback of this design is that the flow rate inside the mixer is relatively slow, resulting in poor mixing performance.

[0004] Therefore, an internally adjustable inlet size crude oil mixer is proposed to solve the problems of slow response to flow and pressure and poor mixing effect caused by the independent setting of valve devices in the prior art. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a crude oil mixer with an internally adjustable inlet size. A flow and pressure control device is designed and directly integrated into the mixer, allowing for faster adjustment of the pressure and flow rate within the container. This structure also achieves a better mixing effect. The purpose of this invention is achieved as follows:

[0006] This utility model proposes a crude oil mixer with an internally adjustable inlet size. It is characterized by comprising a mixer and a flow guide shroud. The mixer is cylindrical, and a mixing chamber is formed inside the mixer. Four telescopic portions are installed on the outer circumference of the mixer, extending into the mixing chamber. Baffles are movably installed inside each telescopic portion, and a transmission device is also installed inside the telescopic portion. The baffles move up and down within the telescopic portion under the drive of the transmission device. One end of the flow guide shroud is fitted against the inner wall of the mixer, and the other end is fitted against the baffles. The flow guide shroud is made of a flexible material.

[0007] Furthermore, in order to precisely adjust the inlet size, a control device is installed on the upper part of the mixer, and all the transmission devices are electrically connected to the control device.

[0008] Furthermore, to enhance waterproofing, the drainage cover is made of rubber.

[0009] Furthermore, to facilitate the opening and closing of the baffle, the transmission device includes a friction rod and a motor, the motor driving the friction rod to move up and down.

[0010] Furthermore, in order to meet most mixing needs, the mixer has an inner diameter range of 1000mm-1500mm and an outer diameter range of 1100mm-1600mm.

[0011] Furthermore, to meet most of the mixing requirements, the height of the baffle is 500-750mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are: through the coordinated operation of the adjustable telescopic part and the baffle, it can respond to changes in crude oil flow and pressure in real time and quickly, with a simpler structure and faster adjustment speed;

[0013] By using a flow hood, the mixer can adjust both the flow rate and pressure internally, resulting in a faster response and better performance. Attached Figure Description

[0020] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0021] Example 1

[0022] This utility model provides a crude oil mixer 4 with an internally adjustable inlet size, including a mixer 4 and a flow guide 9. The mixer 4 is cylindrical, and a mixing chamber 5 is formed inside the mixer 4. A telescopic part 1 is installed on the outer peripheral surface of the mixer 4, which extends into the mixing chamber 5. There are 4 telescopic parts 1. A baffle 2 is movably installed inside the telescopic part 1. A transmission device 7 is also installed inside the telescopic part 1. The baffle 2 moves up and down inside the telescopic part 1 under the drive of the transmission device 7. One end of the flow guide 9 is fitted with the inner wall of the mixer 4, and the other end of the flow guide 9 is fitted with the baffle 2. The material of the flow guide 9 is flexible.

[0023] In this embodiment, a control device 3 is installed on the upper part of the mixer 4, and the transmission device 7 is electrically connected to the control device 3; the material of the diversion shroud 9 is rubber; the transmission device 7 includes a friction rod 6 and a motor 8, and the motor 8 drives the friction rod 6 to move up and down; the inner diameter of the mixer 4 is 1000mm and the outer diameter is 1100mm; the height of the baffle 2 is 500mm.

[0024] Example 2

[0025] Another embodiment of this utility model provides a crude oil mixer 4 with an internally adjustable inlet size, including a mixer 4 and a flow guide 9. The mixer 4 is cylindrical, and a mixing chamber 5 is formed inside the mixer 4. A telescopic part 1 that extends through the mixing chamber 5 is installed on the outer peripheral surface of the mixer 4. There are 4 telescopic parts 1. A baffle 2 is movably installed inside the telescopic part 1. A transmission device 7 is also installed inside the telescopic part 1. The baffle 2 moves up and down inside the telescopic part 1 under the drive of the transmission device 7. One end of the flow guide 9 is fitted with the inner wall of the mixer 4, and the other end of the flow guide 9 is fitted with the baffle 2. The material of the flow guide 9 is a flexible material.

[0026] In this embodiment, a control device 3 is installed on the upper part of the mixer 4, and the transmission device 7 is electrically connected to the control device 3; the material of the drain cover 9 is rubber; the transmission device 7 includes a friction rod 6 and a motor 8, and the motor 8 drives the friction rod 6 to move up and down; the inner diameter of the mixer 4 is in the range of 1500mm, and the outer diameter is in the range of 1600mm; the height of the baffle 2 is 750mm.

[0027] In operation, crude oil and the mixture enter from the left side of the mixing chamber 5, pass through the guide hood 9, and then flow out from the left side of the mixing chamber 5 after reaction. Figure 3 As shown, this state indicates that the flow hood 9 and baffle 2 are fully closed. In this state, crude oil and the mixture do not enter the mixing chamber 5. Figure 4As shown, this state is the semi-closed state of the flow hood 9 and the baffle 2. At this time, crude oil and the mixture enter the mixing chamber 5, and the flow rate and pressure are half of those when it is fully open. Compared with the prior art where the valve is directly set in front of the mixer 4, this integrated structure allows the pressure and flow rate inside the container to be adjusted more quickly, and at the same time, a better mixing effect is achieved through this structure.
