Description

Technical Field

[0001] The utility model relates to the technical field of biodiesel storage, in particular to an environment-friendly biodiesel storage tank. Background Art

[0002] The vertical oil storage tank is a device with strict control for safe use, which can be used either above ground or buried underground. Compared with ordinary oil storage tanks, the service life of the vertical oil storage tank can be extended by 3 - 5 times. It has high advantages in terms of use efficiency and cost performance, can save energy and protect the environment, and at the same time ensures the high efficient use rate of the equipment. It is a safe, efficient and environment-friendly storage device.

[0003] However, the long-term storage of biodiesel will be affected by the environment such as air, heat, metal, peroxide, light and microorganisms, and oxidation, polymerization, degradation and other reactions will occur, resulting in the biodiesel being unable to be used as fuel continuously. Therefore, biodiesel needs to be better sealed for storage, and sampling detection needs to be carried out regularly. When sampling, representative sampling points need to be selected, and the influence of sampling instruments on biodiesel needs to be prevented. So sampling is not a convenient thing. Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides an environment-friendly biodiesel storage tank. By arranging a hose that can move up and down in a vertical tank body, one end of the hose is connected to a sampling pipe to take samples at different liquid levels. Sampling is convenient and there is no need to worry about the pollution of biodiesel during sampling.

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

[0006] An environment-friendly biodiesel storage tank, including a tank body, a sampling port arranged on the tank body, a lead screw and a slider penetrated by the lead screw. A sampling pipe is movably installed in the sampling port. A hose connected to the sampling pipe is installed in the tank body. The lead screw is vertically installed in the tank body, one end of which is in transmission cooperation with the sampling pipe, and the other end of the hose is fixed to the slider and is controlled to move up and down in the tank body.

[0007] Preferably, the lead screw is arranged close to the inner wall of the tank body, and the side of the slider abuts against the inner wall of the tank body.

[0008] Preferably, the sampling pipe penetrates through the sampling port and is in rotational cooperation with it. One end of the sampling pipe is sealed and has grooves on its outer circumference for liquid to pass through.

[0009] Preferably, a housing is installed in the tank body. The housing covers the sampling pipe, and the other end of the hose is communicated with the inside of the housing, and diesel can flow from the tank body into the housing.

[0010] Preferably, the lead screw is rotatably mounted on the housing, and the end of the lead screw is smooth and penetrates into the housing to be in meshing transmission cooperation with the sampling pipe teeth.

[0011] Preferably, the other end of the sampling pipe is open and movably connected with a negative pressure pipeline, and the side of the negative pressure pipeline is communicated with the outside.

[0012] Preferably, a piston is installed in the negative pressure pipeline.

[0013] Preferably, a plurality of small holes are formed in the piston, and one-way valves are installed on the small holes.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides an environment-friendly biodiesel storage tank, which centralizes the control of sampling liquid discharge and the control of sampling liquid level at the sampling pipe, making the sampling operation more convenient, eliminating the need for climbing to sample and carrying a sampler to sample, reducing the contact between biodiesel and the outside, and making the storage of biodiesel safer and more environment-friendly. Moreover, the mechanical transmission is simple and not easily damaged or interfered with.

[0016] In the utility model, a negative pressure pipeline with a piston is arranged at the end of the sampling pipe to provide certain power for sampling, and it can conveniently cope with the situation where the biodiesel flows out slowly when the storage in the tank is less or the hose is bent.

[0017] In the utility model, a housing covering the sampling pipe is arranged in the tank, and the hose is connected to the housing, avoiding the direct connection between the sampling pipe and the hose, and preventing the rotation of the sampling pipe from accelerating the damage of the hose.

[0018] The utility model utilizes the cooperation of the lead screw and the slider, which not only conveniently adjusts the end of the hose to any height in the tank, but also reduces the difficulty of adjustment by virtue of the lubricating effect of the biodiesel itself.

[0019] In the utility model, a plurality of small holes are formed in the piston, and one-way valves are installed on the small holes, thereby avoiding installing one-way valves inside the negative pressure pipeline and the sampling pipe, and reducing the interference with natural sampling.

[0032] Embodiment:

[0033] Please refer toFigure 1 - Figure 6 , the present utility model provides an environment-friendly biodiesel storage tank, including a tank body 1, a lead screw 5, a slider 6, etc. The tank body 1 is vertically arranged. A sampling port 2 is provided at a position near the bottom on the side of the tank body 1, and a rotatable sampling pipe 3 is installed in the sampling port 2; the lead screw 5 is vertically installed near the side of the tank body 1, the slider 6 is penetrated by the lead screw 5 and is in threaded cooperation, and one side of the slider 6 abuts against the inner wall of the tank body 1. Thus, by rotating the lead screw 5, the vertical movement of the slider 6 can be controlled. A flexible hose 4 is arranged in the tank body 1. One end of the flexible hose 4 is installed on the slider 6, and the other end is installed and communicated with the sampling pipe 3. The biodiesel in the tank body 1 can flow from the slider 6 through the flexible hose 4 to the sampling pipe 3 and flow out through the sampling pipe 3. By controlling the position of the slider 6, rapid sampling at different liquid levels can be realized, ensuring the accuracy and reliability of sampling and facilitating the monitoring of the quality and characteristics of biodiesel.

[0034] In the embodiment of the present application, a housing 7 is installed in the tank body 1, and the housing 7 covers the sampling pipe 3 penetrating into the tank body 1. The other end of the flexible hose 4 is installed on the housing 7 and communicated with the internal space of the housing 7. Therefore, when sampling biodiesel, it first flows into the housing 7 and then flows to the sampling pipe 3; since the sampling pipe 3 is rotatably arranged, rotating the sampling pipe 3 outside the tank body 1 will not affect the flexible hose 4.

[0035] Further, the lead screw 5 is installed on the housing 7. The outer periphery of the bottom end of the lead screw 5 is smooth and penetrates into the interior of the housing 7. The end of the sampling pipe 3 in the housing 7 is hermetically arranged, and a convex rod with a smaller shaft diameter extends from the end. Bevel gears are installed on both the convex rod and the end of the lead screw 5 for vertical meshing, so that the sampling pipe 3 can control the rotation of the lead screw 5 and further adjust the position of the slider 6.

[0036] In the present application, by setting the cooperation of the lead screw 5 and the slider 6 to control the flexible hose 4, sampling at different positions in the tank body 1 can be repeatedly satisfied. In addition, the cooperation of the lead screw 5 and the sampling pipe 3 can select and control the sampling position while controlling the opening and closing of the sampling pipe 3, which is more convenient to use, and the lubricating effect of the biodiesel itself also reduces the adjustment resistance.

[0037] It should be noted that the end of the sampling pipe 3 in the housing 7 is hermetically arranged, but its outer periphery is evenly grooved to allow biodiesel to flow through, and the side grooves can facilitate the drainage of the biodiesel in the housing 7. At the same time, the end of the sampling pipe 3 extends out a convex rod with a smaller shaft diameter, which is convenient to select a small-sized bevel gear to make full use of the internal space of the housing 7.

[0038] In the embodiment of the present application, an anti-slip sleeve is installed on the outer periphery of the sampling pipe 3 extending to the outside of the tank body 1, which is convenient for controlling the rotation of the sampling pipe 3.

[0039] One end of the sampling pipe 3 extending outside the tank body 1 is open and movably connected with a negative pressure pipe 8. The negative pressure pipe 8 is communicated with the sampling pipe 3, and an outlet is arranged on the side of the negative pressure pipe 8 and communicated with the outside. Therefore, when sampling biodiesel, it flows out through the hose 4, the housing 7, the sampling pipe 3, and the negative pressure pipe 8. The outlet of the negative pressure pipe 8 is in a sealed state before and after sampling, and the outlet of the negative pressure pipe 8 is temporarily opened during sampling; in order to ensure the accuracy of sampling, the biodiesel previously filled in the hose 4, the housing 7, the sampling pipe 3, and the negative pressure pipe 8 can be discharged and then collected for sampling detection.

[0040] It should be noted that a piston 9 is installed inside the negative pressure pipe 8, and the piston rod for controlling the piston 9 passes through the end of the negative pressure pipe 8. The piston 9 can be manually controlled to move through the piston rod to accelerate the outflow of biodiesel.

[0041] When there is less biodiesel stored in the tank body 1 or the hose 4 is bent, controlling the piston 9 can promote the flow of biodiesel.

[0042] It should be noted that a plurality of small holes 91 are formed in the piston 9, and one-way valves 92 are installed on the small holes 91. Thus, it is not necessary to install one-way valves inside the negative pressure pipe 8 and the sampling pipe 3, reducing the interference with natural sampling.

[0043] In this application, the control of the sampling liquid discharge and the control of the sampling liquid level are centrally set, making the sampling operation more convenient for single-person operation, eliminating the inconvenience of climbing for sampling and carrying a sampler for sampling, reducing the contact between biodiesel and the outside, facilitating the long-term storage of biodiesel, and being more safe and environmentally friendly. Moreover, the mechanical transmission is simple and not easily damaged or interfered with.

[0044] In some embodiments of this application, an ultrasonic sensor can also be installed on the top of the tank body 1. By monitoring the position of the slider 6, the position of the slider 6 in the tank body 1 can be more accurately understood through the ultrasonic sensor, and a more accurate sampling position can be obtained.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been completely and effectively achieved. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the principle, the embodiments of the present invention can have any deformation or modification.
