Description

Technical Field

[0001] The utility model relates to the technical field related to stratified tanks, in particular to a stratified tank for crude oil processing. Background Art

[0002] A stratified liquid storage tank is a container used to store various liquid materials. It usually adopts a vertical or horizontal single-layer or double-layer structure. The general stratified liquid storage tank has certain shortcomings because it discharges the sediment at the bottom when discharging the liquid, which reduces the quality of the discharged liquid.

[0003] For example, a stratified oil storage tank with publication number CN208813917U has two oil outlets on the side wall. When the oil stored in the tank is more than half full, the oil can be discharged through the first oil outlet, and when the oil stored in the tank is less than half full, the oil can be discharged through the second oil outlet, thus achieving stratified oil discharge, minimizing the stirring probability of the sediment at the bottom of the tank, and improving the oil discharge quality. At the same time, an oil pump extraction port is provided on the top wall of the oil tank, which is convenient for using the oil pump to extract oil in stratified layers.

[0004] The above-mentioned prior art has the following technical problems: although the existing stratified liquid storage tank can discharge the oil in the upper layer and the lower layer respectively through the upper and lower sets of oil outlets, the upper oil outlet can only discharge the oil on the horizontal plane of the upper oil outlet, and the liquid level below the upper oil outlet needs to be discharged through the oil outlet at the bottom of the tank body, which will cause the sediment at the bottom of the tank to be discharged together, reducing the quality of the oil output.

[0005] Therefore, we propose a stratified tank for crude oil processing to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a stratified tank for crude oil processing, so as to solve the problem raised in the above background technology that the existing stratified liquid storage tanks on the market can discharge the oil of the upper layer and the lower layer respectively through the upper and lower groups of oil outlets, but the upper oil outlet can only discharge the oil on the horizontal plane of the upper oil outlet, and the liquid level below the upper oil outlet needs to be discharged through the oil outlet at the bottom of the tank body, which will cause the sediment at the bottom of the tank to be discharged together, thereby reducing the quality of the oil output.

[0007] To achieve the above object, the utility model provides the following technical solution: a stratified tank for crude oil processing, comprising a tank body, wherein a partition is fixedly connected to the inner wall of the tank body, a sealing groove is provided at the bottom of the tank body, and an oil inlet is connected through the upper end of the tank body;

[0008] Also includes:

[0009] The slide cylinder is fixedly installed in a groove opened on the top of the tank body, and a measuring piece is slidably connected to the inner wall of the slide cylinder, and a buoyancy ball is fixedly installed at the lower end of the measuring piece;

[0010] The outer tube is fixedly installed on the top of the tank body, and a liquid inlet is opened on the outer wall of the outer tube, and the inner tube is slidably connected to the inner tube on the inner wall of the outer tube, and a liquid outlet is opened on the outer wall of the inner tube, and a mounting block is fixedly installed at the lower end of the tank body, and a turntable is rotatably installed at the lower end of the mounting block;

[0011] The main airbag is fixedly installed at the bottom of the tank body, the guide tube is fixedly installed in the groove opened at the lower end of the tank body, and the auxiliary airbag is fixedly installed inside the sealing groove.

[0012] Preferably, two groups of through holes are opened on the surface of the partition, and a sealing cover is bolted above the oil inlet.

[0013] Preferably, the outer wall of the measuring member is in contact with the inner wall of the slide cylinder, and the buoyancy ball is filled with nitrogen.

[0014] Preferably, the outer wall of the outer tube is provided with two groups of upper and lower liquid inlets, and the diameter of the liquid inlet is equal to the size of the liquid outlet.

[0015] Preferably, the turntable is threadedly connected with the external thread at the lower end of the inner tube through the internal thread.

[0016] Preferably, the catheter head end is connected to the lower end of the main airbag, and the catheter tail end is connected to the tail end of the auxiliary airbag.

[0017] Preferably, the main airbag and the auxiliary airbag are both symmetrically arranged in two groups with respect to the tank body, and the main airbag is made of elastic rubber.

[0018] Compared with the prior art, the utility model has the following beneficial effects: the stratified tank for crude oil processing can stratify the oil in the tank and, through the provided oil discharge assembly, can discharge the oil below the horizontal plane of the oil outlet, and through the provided sealing and detection assembly, can prevent the oil from leaking through the gap of the tank body. The specific contents are as follows:

[0019] 1. A partition is provided. Before use, the crude oil to be stored is first passed into the tank through the oil inlet, and then the oil inlet is sealed. After the crude oil in the tank is left to stand for a period of time, the sediment in the crude oil passes through the two groups of partitions and settles at the bottom of the tank;

[0020] 2. A measuring piece is provided. When the oil in the tank is stored or released, the buoyancy ball at the lower end of the measuring piece will drive the measuring piece to slide on the inner wall of the slide tube as the liquid level in the tank rises or falls, thereby measuring the amount of oil in the tank. At the same time, when the oil in the tank leaks, the height change of the measuring piece can also promptly remind the operator to maintain the tank;

[0021] 3. An outer tube is provided. When the oil in the tank is drained, it is first discharged through the oil discharge port on the upper left end of the tank. When the liquid level in the tank is lower than the oil discharge port, the turntable at the lower end of the mounting block is rotated so that the turntable drives the inner tube to rotate through the thread, thereby making the inner tube slide upward on the inner wall of the outer tube. When the liquid outlet at the upper end of the inner tube is aligned with the liquid inlet opened on the outer tube, the oil below the oil discharge port is discharged through the inner tube;

[0022] 4. An inner tube is provided. After the oil is discharged, if the oil below the partition needs to be discharged, the turntable is rotated in the opposite direction so that the turntable drives the inner tube to slide downward on the inner wall of the outer tube. When the liquid outlet at the lower end of the inner tube is aligned with the liquid inlet at the lower end of the outer tube, the oil below the partition can be discharged through the inner tube. At the same time, since the upper end of the inner tube blocks the liquid inlet above the outer tube, it can avoid the pure oil from being discharged together.

[0023] 5. A main airbag and a secondary airbag are provided. When there is sufficient oil in the tank, the pressure of the oil is greater than the pressure of the air in the main airbag, so that the main airbag is compressed, and the main airbag passes air into the secondary airbag through the conduit, so that the connection at the lower end of the tank can be sealed for the second time to prevent the oil in the tank from leaking out.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1: Please refer to Figure 1 The utility model provides the following technical solutions. The existing stratified oil storage tank will discharge the sediment at the bottom of the tank body 1 when discharging oil, thereby reducing the quality of the discharged oil. In order to solve this technical problem, the present embodiment discloses the following technical contents: a stratified tank for crude oil processing, comprising a tank body 1, a partition 101 is fixedly connected to the inner wall of the tank body 1, a sealing groove 102 is opened at the bottom of the tank body 1, and an oil inlet 2 is connected through the upper end of the tank body 1;

[0033] When the oil in the tank body 1 is drained, it is first discharged through the oil discharge port on the upper left end of the tank body 1. When the liquid level in the tank body 1 is lower than the oil discharge port, the turntable 7 at the lower end of the mounting block 6 is rotated to make the turntable 7 drive the inner tube 8 to rotate, thereby making the inner tube 8 slide upward on the inner wall of the outer tube 5. When the liquid outlet 81 at the upper end of the inner tube 8 is aligned with the liquid inlet 51 provided in the outer tube 5, the oil below the upper oil discharge port is discharged through the inner tube 8, thereby avoiding the sediment at the bottom of the tank body 1 from being discharged together.

[0034] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. By setting a stratified oil discharge component, the crude oil in the tank body 1 is discharged in layers, thereby avoiding the discharge of sediment at the bottom of the tank body 1 when discharging the crude oil. Figure 1-Figure 4 and Figure 6 As shown, the outer tube 5 is fixedly installed on the top of the tank body 1, and the outer wall of the outer tube 5 is provided with a liquid inlet 51, and the inner wall of the outer tube 5 is slidably connected with the inner tube 8, and the outer wall of the inner tube 8 is provided with a liquid outlet 81, and the lower end of the tank body 1 is fixedly installed with a mounting block 6, and the lower end of the mounting block 6 is rotatably installed with a turntable 7; the surface of the partition 101 is provided with two groups of through holes, and a sealing cover is bolted above the oil inlet 2. The outer wall of the outer tube 5 is provided with two groups of upper and lower liquid inlets 51, and the diameter of the liquid inlet 51 is equal to the size of the liquid outlet 81. The turntable 7 is threadedly connected with the external thread at the lower end of the inner tube 8 through the internal thread.

[0035] Before use, firstly, the crude oil to be stored is introduced into the tank body 1 through the oil inlet 2, and then the oil inlet 2 is sealed. After the crude oil in the tank body 1 is left to stand for a period of time, the sediment in the crude oil passes through the two groups of partitions 101 and settles at the bottom of the tank body 1. When the oil in the tank body 1 is drained, it is first discharged through the oil drain port at the upper left end of the tank body 1. When the liquid level in the tank body 1 is lower than the oil drain port, the turntable 7 at the lower end of the mounting block 6 is rotated so that the turntable 7 drives the inner tube 8 to rotate through the thread, so that the inner tube 8 slides upward on the inner wall of the outer tube 5, so that the upper end of the inner tube 8 When the liquid outlet 81 of the inner tube 8 is aligned with the liquid inlet 51 of the outer tube 5, the oil below the oil outlet is discharged through the inner tube 8. After the oil is discharged, if the oil below the partition 101 is to be discharged, the turntable 7 is rotated in the opposite direction so that the turntable 7 drives the inner tube 8 to slide downward on the inner wall of the outer tube 5. When the liquid outlet 81 at the lower end of the inner tube 8 is aligned with the liquid inlet 51 at the lower end of the outer tube 5, the oil below the partition 101 can be discharged through the inner tube 8. At the same time, since the upper end of the inner tube 8 blocks the liquid inlet 51 above the outer tube 5, the sediment at the bottom of the tank body 1 is prevented from being discharged together.

[0036] Embodiment 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiments 1 and 2. By setting a monitoring component, the oil in the tank 1 is monitored in real time to avoid oil leakage. Figure 1-Figure 2 and Figure 5 As shown, the slide 3 is fixedly installed in the groove opened above the tank body 1, and the inner wall of the slide 3 is slidably connected with a measuring piece 4, and a buoyancy ball 41 is fixedly installed at the lower end of the measuring piece 4; the main airbag 9 is fixedly installed at the bottom of the tank body 1, and the conduit 10 is fixedly installed in the groove opened at the lower end of the tank body 1, and the auxiliary airbag 11 is fixedly installed inside the sealing groove 102. The outer wall of the measuring piece 4 fits the inner wall of the slide 3, and the buoyancy ball 41 is filled with nitrogen. The head end of the conduit 10 is connected to the lower end of the main airbag 9, and the tail end of the conduit 10 is connected to the tail end of the auxiliary airbag 11. The main airbag 9 and the auxiliary airbag 11 are both symmetrically arranged in two groups with respect to the tank body 1, and the main airbag 9 is made of elastic rubber.

[0037] When the oil in the tank body 1 is stored or released, the buoyancy ball 41 at the lower end of the measuring piece 4 will drive the measuring piece 4 to slide on the inner wall of the slide 3 as the liquid level in the tank body 1 rises or falls, thereby measuring the amount of oil in the tank body 1. At the same time, when the oil in the tank body 1 leaks, the height change of the measuring piece 4 can also promptly remind the operator to maintain the tank body 1. When there is sufficient oil in the tank body 1, the pressure of the oil is greater than the pressure of the air in the main airbag 9, so that the main airbag 9 is compressed, allowing the main airbag 9 to pass air into the auxiliary airbag 11 through the conduit 10, so that the connection at the lower end of the tank body 1 can be re-sealed to prevent the oil in the tank body 1 from leaking.

[0038] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
