Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil collection and storage, in particular to a waste collection and storage device for lubricating oil. Background Art

[0002] Waste oil is generated in industries such as automobile maintenance. Currently, a dedicated collection and storage device is used to collect and store waste oil. The device generally includes a storage tank and a collection funnel arranged on the storage tank. The collection funnel collects the outflowing oil and introduces it into the storage tank below for temporary storage. After the storage tank below is full, the waste oil in the storage tank is uniformly introduced into the oil storage container for unified treatment.

[0003] Most of the existing engine oil storage containers are large-volume storage barrels with an opening on the top of the storage barrel. When the engine oil in the storage tank is discharged into the storage barrel, a discharge port is provided at the bottom of the storage tank, and the discharge port is connected to a discharge pipe. An air connection head is provided on the top of the storage tank. When discharging, the air connection head is connected to the high-pressure gas source, the end of the discharge pipe is inserted into the storage barrel, and the pipeline connecting the storage tank and the collecting funnel is closed. Compressed gas is introduced into the storage tank to increase the internal air pressure, thereby using the air pressure to press the waste engine oil in the storage tank into the storage barrel. It is simple and convenient to use.

[0004] However, in actual use, during the oil discharge process, as the oil becomes less and less, the oil level in the storage tank gradually falls below the discharge port. When it is lower than the discharge port, compressed gas and oil will be discharged together. The high-speed outflow of the airflow will produce a jet at the outlet of the discharge pipe, and the mixed oil will be sprayed out at high speed, causing oil splashing. At this time, when the oil level in the storage barrel is high, the oil will splash out from the barrel mouth of the storage barrel, causing dirt on the bottom surface around the oil storage barrel, and the oil splashing on the ground will also create a safety hazard of slipperyness.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0022] Please refer to Figure 1-Figure 4 In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a waste collection and storage device for lubricating oil includes a storage tank 1, an air connection head 4 and a derivation pipe 5 arranged on the storage tank 1, and a rigid tube 52 connecting the derivation pipe 5 and the interior of the storage tank 1 is also provided on the storage tank 1, and the end of the rigid tube 52 extending into the storage tank 1 is connected to a liquid level valve.

[0023] Specifically, the storage tank 1 is a rigid metal tank with a roller 3 at the bottom and a receiving funnel 2 at the top. As an embodiment, the receiving funnel includes a connecting pipe 21 and a funnel 22. The connecting pipe 21 includes a connecting end 210 threadedly connected to the upper end of the storage tank 1. The waste oil can be connected to the tank body through the funnel 22. After the waste oil in the storage tank is full, the receiving pipe can be separated from the tank body, and a plug cover (not shown in the figure) can be threadedly connected at the position where the storage tank is connected to the connecting pipe 21. A rigid pipe 52 is provided at the bottom of the storage tank 1, and a liquid level valve is provided at the end of the rigid pipe 52. By setting the liquid level, the liquid level valve is turned off. Valve, when draining out the waste oil in the storage tank, move the storage tank 1 to the side of the storage barrel, extend the end of the outlet pipe 5 into the storage barrel, block the storage tank with a plug cover (not shown in the figure), and then connect it to the high-pressure gas source through the gas connector 4. The gas passes through the storage tank. Since the oil level in the storage tank 1 is high at this time, the liquid level valve is in an open state. Therefore, the oil can be drained out of the waste oil through the rigid tube 52 and the outlet pipe 5. As the liquid level drops, the liquid level valve closes, which can prevent airflow from flowing out, thereby reducing the situation of oil splashing due to airflow outflow. The liquid level valve can be a liquid level valve in the existing technology.

[0024] Further, as a specific implementation method, refer to Figure 3-Figure 6 In the radial direction, a mounting channel 11 is provided on the side wall of the storage tank 1 , and a connecting flange 51 is coaxially provided in the middle area of the rigid tube 52 , and the connecting flange 51 is coaxially connected to the mounting channel 11 .

[0025] Specifically, an installation channel 11 is opened on the side wall of the storage tank, and a first connecting flange is provided at the end of the installation channel 11. The rigid tube 52 is made of stainless steel, and a connecting flange 51 is welded to the middle area of the rigid tube, which can be fixedly connected to the first connecting flange through the connecting flange. A liquid level valve is provided at one end of the rigid tube extending into the tank body, and the other end is connected to the outlet pipe 5. The outlet pipe is made of a flexible oil-resistant rubber tube.

[0026] Further, as a specific embodiment, the specific structure of the liquid level valve is as follows: Figure 2-Figure 4 The liquid level valve includes a valve body 53 sleeved on the end of a rigid tube 52, a driving rod 54 with one end hingedly connected to the valve body 53 through a hinge shaft 531, and a float 55 arranged at the other end of the driving rod 54. The hinge shaft 531 is arranged horizontally and perpendicular to the axis of the rigid tube 52, and the length direction of the driving rod 54 is perpendicular to the axis of the hinge shaft.

[0027] Specifically, the valve body 53 is a columnar structure coaxially arranged with the rigid tube 52, one end of which is connected to the rigid tube sleeve. An ear plate 530 is provided on the valve body 53, one end of the driving rod 54 is hingedly connected to the ear plate 530 through a hinge shaft 531, and the other end is provided with a float 55. The liquid level valve drives the driving rod to swing through the buoyancy and gravity of the float 55, thereby driving the valve body to open and close, thereby controlling the opening and closing of the liquid level valve.

[0028] Further, as a specific embodiment, refer to Figure 2-Figure 6 The installation channel 11 is a cylindrical channel, and the diameter of the float 55 is smaller than the diameter of the installation channel 11.

[0029] Specifically, by setting the diameter of the float 55 to be smaller than the installation channel 11, referring to Figure 6 , is a structural diagram of the oil level in the tank body when the level valve is in the closed state. At this time, the driving rod is in contact with the valve body, and the linear direction of the driving rod is substantially parallel to the axis of the rigid tube 52. By this arrangement, when the driving rod reaches the state Figure 6 In the state shown, it is convenient to separate and install the rigid pipe, the liquid level valve and the tank body, thereby facilitating the subsequent maintenance of the liquid level valve.

[0030] Further, as a specific embodiment, refer to Figure 5 、 Figure 6The valve body 53 is provided with a first valve channel 533 which is connected to the rigid tube 52 and is coaxially arranged, and a second valve channel 534 which is vertically arranged and intersecting with the first valve channel. A valve stem 535 is guided in the second valve channel 534, and an extrusion column 5361 corresponding to the drive rod 54 is provided at the upper end of the valve stem extending out of the valve body.

[0031] Furthermore, the valve stem 535 is provided with a third valve passage 536 adapted to the first valve passage 533. The lower end of the second valve passage 534 is threadedly connected to an end cap 538. A compression spring 537 is provided between the end cap 538 and the valve stem 535. Specifically, an adjustment blind hole is coaxially provided at one end of the first valve passage 533, which is sleeved with the end of the rigid tube 52. Then, a locking bolt is used to lock the rigid tube and the valve body in place. Figure 5 , is a schematic diagram of the structure of the liquid level valve in the open state. At this time, the upper end of the valve stem is pushed against the upper end of the second valve channel under the elastic force of the compression spring 537, so that the third valve channel 536 is connected to the first valve channel 533. At this time, the waste oil in the tank body can flow into the rigid tube 52 through the first valve channel, the third valve channel, and the first valve channel, and then be discharged. Figure 6 When the oil in the tank is discharged and the liquid level is lowered, the float 55 gradually moves downward, and the drive rod swings downward. The drive rod can press the upper end of the extrusion column 5361, and under the action of the gravity of the float, the valve stem 535 is pushed to squeeze the compression spring 537 downward until Figure 6 In the state shown, the third valve channel 536 and the first valve channel 533 are disconnected and connected alternately, and the liquid level valve is switched to the closed state. Figure 6 In actual use, the other end of the first valve channel 533 is connected to a bend pipe 539, the lower end of which is bent away from the driving rod. The oil in the tank is discharged by setting the bend pipe 539. Figure 6 In the closed state shown, the liquid level in the tank body is still higher than the lower mouth of the elbow, thereby effectively preventing the high-pressure gas in the tank body from leaking out and avoiding the situation where the engine oil splashes due to the leakage of high-pressure airflow.

[0032] Further, as a preferred embodiment, refer to Figure 5 The extrusion post 5361 is eccentrically disposed with respect to the valve stem 535, and a guide channel 5341 is provided at the upper end of the second valve passage 534 to guide and cooperate with the extrusion post 5361. Specifically, the valve stem 535 and the extrusion post 5361 are integrally formed. By eccentrically disposing the extrusion post and the valve stem 535, and providing a guide channel 5341 at the end of the second valve passage to guide and cooperate with the extrusion post, the valve stem can be circumferentially limited, thereby preventing the valve stem from circumferentially rotating along the axis, and ensuring that the third valve passage is arranged parallel to the first valve passage.

[0033] Specifically, the end cover 538 is threadedly connected to the valve body, and a flow hole is provided through the end cover.

[0034] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
