A desktop centrifuge for measuring crude oil moisture

Abstract

The utility model belongs to the field of centrifuges, in particular to a desktop centrifuge for determining the moisture content of crude oil. Most of the existing centrifuges for determining the moisture content of crude oil install the equipment at a designated position. When the device needs to be moved, since the equipment is relatively heavy, it requires multiple people to carry it, and the equipment cannot be quickly and easily moved to a location where it is needed to be used. The following scheme is now proposed, which includes a centrifuge body, the bottom of which is fixedly connected with a box body. In the utility model, the machine is lifted, and then a foot pedal is stepped on to press a roller to the bottom of a through groove 2, so that the centrifuge body can be quickly and easily moved to a location where it is needed to be used. A slider and a spring fix a mounting plate that is pressed down. After the centrifuge body moves to a desired placement position, a pull rod and a tension spring release and reset the slider from fixing the mounting plate, so as to avoid shaking of the centrifugal fan body during operation, thereby affecting the separation effect of crude oil and moisture.

Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a desktop centrifuge for determining the moisture content of crude oil. Background Art

[0002] When measuring the water content of crude oil, we first need to separate the crude oil from water. Common dehydration methods include natural sedimentation, chemical precipitation and electric precipitation. However, these separation methods have great defects, such as being time-consuming. In view of the physical properties of water and crude oil, we can also use centrifugal method to dehydrate the crude oil.

[0003] Most of the existing crude oil moisture determination centrifuges are installed at designated locations. When the device needs to be moved, it is heavy and requires multiple people to carry it, so the device cannot be quickly and easily moved to the location where it needs to be used. Utility Model Content

[0004] The utility model aims to solve the problem that most of the existing centrifuges for determining the moisture content of crude oil are installed at designated locations in the prior art. When the device needs to be moved, it is heavy and requires multiple people to carry it, and the device cannot be quickly and easily moved to the location where it needs to be used. A desktop centrifuge for determining the moisture content of crude oil is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A desktop crude oil moisture determination centrifuge comprises: a centrifuge body, a box body is fixedly connected to the bottom of the centrifuge body, a guide rod is fixedly connected between the top inner wall and the bottom inner wall of the box body, and a connecting plate is slidably connected to the outer wall of the guide rod;

[0007] Two mounting plates, the two mounting plates are respectively fixedly connected to the two sides of the connecting plate, and the lower surfaces of the two mounting plates are provided with two rollers for facilitating the movement of the centrifuge body;

[0008] A pressing mechanism, which is located on one side of the connecting plate and is used to press down the four rollers;

[0009] The fixing mechanism is located on the bottom inner wall of the box body and is used to fix the connection plate after being pressed down.

[0010] Furthermore, the pressing mechanism includes a slide plate, which is fixedly connected to one side of the connecting plate. A through groove is opened on one side of the box body. The slide plate is slidably connected inside the through groove. The upper surfaces of the two mounting plates and the connecting plates are fixedly connected with tension springs for resetting the four rollers. The other ends of the three tension springs are fixedly connected to the top inner wall of the box body, and one of the tension springs is sleeved on the outer wall of the guide rod.

[0011] Furthermore, the fixing mechanism includes a fixing block, which is fixedly connected to the bottom inner wall of the box body, a slider slidingly penetrates one side of the fixing block, a pull plate is fixedly connected to one side of the slider, a pull rod is fixedly connected to one side of the pull plate, and a spring is fixedly connected between the pull plate and one side inner wall of the box body.

[0012] Furthermore, one side of the sliding block is an inclined surface.

[0013] Furthermore, one end of the pull rod slides through an inner wall of one side of the box body and is fixedly connected to a pull ring for pulling the pull rod, and one side of the slide board is fixedly connected to a foot pedal for pressing the slide board downward.

[0014] Furthermore, four through slots 2 are provided at the bottom of the box body, and the four rollers are respectively located above the four through slots 2.

[0015] In the present application, when the centrifuge body needs to be moved, the machine is first lifted, and then the foot pedal is stepped on, and then pressed down, driving the slide plate and the connecting plate to move down along the through slot 1 and the guide rod respectively, thereby driving the two mounting plates to move down, and the tension spring is stretched, so that the four rollers are moved to the bottom of the through slot 2 respectively. When the lower surface of the connecting plate contacts the inclined surface of the slider, the slider is driven to move laterally along the inner wall of the fixed block, thereby driving the pull ring and the pull rod to move laterally synchronously, and the spring contracts. When the connecting plate moves to the bottom of the slider 16, the spring rebounds. , so that the pull ring, pull rod, pull plate and slider move in opposite directions, so that the lower surface of the slider contacts the upper surface of the connecting plate, resists the connecting plate, and prevents the roller from rising, which facilitates the movement of the equipment. When the centrifuge body moves to the required installation position, pull the pull ring, thereby driving the pull rod to move horizontally, and the spring contracts, thereby releasing the resistance of the slider to the mounting plate. After the resistance is released, the tension spring contracts, and the mounting plate, connecting plate and roller are pulled into the second through groove from the second, so as to avoid the centrifugal fan body from shaking during operation, which affects the separation effect of crude oil and water.

[0016] In the utility model, the desktop crude oil moisture determination centrifuge can be lifted up and then stepped on the foot pedal to press the roller under the second through slot, so that the centrifuge body can be quickly and easily moved to the place where it needs to be used;

[0017] In the utility model, the desktop centrifuge for measuring the moisture content of crude oil can fix the installation plate after being pressed down by the cooperation of the slider and the spring. After the centrifugal fan body is moved to the desired position, the slider is released and reset from the installation plate by the pull rod and the tension spring, so as to avoid the centrifugal fan body from shaking during operation, thereby affecting the separation effect of crude oil and moisture.

[0018] In the utility model, the machine is lifted, and then the foot pedal is stepped on to press the roller to the bottom of the second through slot, so that the centrifuge body can be quickly and easily moved to the place where it is needed to be used, and the slider and the spring fix the mounting plate after being pressed down. After the centrifuge body is moved to the desired placement position, the pull rod and the tension spring release and reset the fixation of the slider to the mounting plate, thereby preventing the centrifugal fan body from shaking during operation, which affects the separation effect of crude oil and water.
