[0027] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] according to Figures 1 to 4 As shown, this utility model provides a waste oil recycling device with visible oil level observation, including a recycling tank 1. The top surface of the recycling tank 1 is provided with an observation port, and a valve seat 2 is provided at the observation port with a sealed connection. A liquid level rod 3 is slidably connected to the valve seat 2. The bottom of the liquid level rod 3 extends into the recycling tank 1 and is fixed with a float ball 5. The top of the liquid level rod 3 is provided with a first scale line to display the liquid level change in the recycling tank 1 in real time.

[0029] A conventional recycling bin 1 has only one hole, usually located on the top surface of the bin near the perimeter, primarily for emptying the oil from the original container. In this embodiment, a valve seat 2 is fixed directly to the original hole (i.e., the observation port) of the recycling bin 1. An oil level needle penetrates the entire valve seat 2, and a hollow float 5 is fixed at the bottom. The change in oil level is converted into a change in the length of the float 5 relative to the level rod 3, thus clearly indicating the oil level in the waste oil bin recycling device. When the oil level is too high, the level rod 3 and the first scale line on it will directly indicate the level, reminding the operator that the device cannot be refilled and that the storage facility needs to be contacted.

[0030] Preferably, in this embodiment, according to Figure 2 and Figure 3As shown, the valve seat 2 includes a valve cover 21 and a valve body 22. The valve cover 21 is fixedly connected to the upper end of the valve body 22. The upper surface of the valve cover 21 is provided with an arc surface, and a horizontally arranged first limiting rod 23 is fixed on the arc surface. The liquid level rod 3 is slidably connected to the first limiting rod 23. The valve body 22 is sealed to the observation port. Setting the upper surface of the valve cover 21 as an arc surface reduces the friction area between the liquid level rod 3 and the valve cover 21, making it easier for the buoyancy of the float 5 to allow the liquid level rod 3 to slide flexibly. In addition, since the liquid level rod 3 has a certain length, after the contact area between the valve cover 21 and the liquid level rod 3 is reduced, the liquid level rod 3 is supported at fewer points, and the first limiting rod 23 can support and fix the liquid level rod 3.

[0031] Preferably, in this embodiment, the valve body 22 has a hollow structure, and a horizontally arranged second limiting rod 24 is fixed on the inner sidewall of the bottom of the valve body 22. The liquid level rod 3 is slidably connected to the first limiting rod 23. Similarly, there is no direct contact between the valve body 22 and the liquid level rod 3, resulting in low overall friction between the liquid level rod 3 and the valve seat 2. Changes in the liquid level in the recovery tank 1 can be effectively reflected on the liquid level rod 3 by the buoyancy of the float 5. The second limiting rod 24 fixes and supports the liquid level rod 3. The stability of the liquid level rod 3 is ensured by fixing the liquid level rod 3 with the first limiting rod 23 and the valve cover 21. In the implementation process, multiple sets of the first limiting rod 23 and the second limiting rod 24 can be set, and there are not only the first limiting rod 23 and the second limiting rod 24. It is only necessary to ensure that the through holes for sliding connection of the liquid level rod 3 on all limiting rods are concentric and have the same diameter, so that the buoyancy of the float 5 can allow the liquid level rod 3 to slide flexibly.

[0032] Preferably, in this embodiment, according to Figure 3 As shown, a sealing ring 25 is also fixed at the connection between the valve body 22 and the valve cover 21. The outer diameter of the sealing ring 25 is larger than the diameter of the observation port, and the sealing ring 25 is sealed to the observation port. The sealing ring 25 serves two purposes: First, it ensures the stability of the connection between the valve seat 2 and the observation port. The oil level exerts a continuous buoyancy force on the float 5, which is then transmitted to the level rod 3. The level rod 3 experiences friction due to its connection with the valve cover 21. The sealing ring 25 counteracts this friction, ensuring a secure connection between the valve seat 2 and the recovery tank 1. Second, it ensures the sealing performance of the valve seat 2 to the observation port. Although there is a sliding connection between the level rod 3 and the valve cover 21, the small gap is negligible and does not affect the final sealing performance. Furthermore, lubricant can be applied to the connection between the valve cover 21 and the level rod 3 to achieve a liquid seal. Under the buoyancy of the oil on the float 5, the lubricant on the level rod 3 will not directly contact the oil in the recovery tank 1, preventing oil contamination.

[0033] Preferably, in this embodiment, the sealing ring 25 is an elastic rubber ring structure, which utilizes the elastic properties of the rubber material to ensure that the connection between the valve seat 2 and the observation port is sufficiently stable and sealed.

[0034] Preferably, in this embodiment, according to Figure 1 As shown, a transparent viewing window 6 is installed on the side wall of the recycling bin 1. The observation port is located on one side of the top surface of the recycling bin 1, and the viewing window 6 is located on the same side as the observation port. The liquid level rod 3 is within the field of view of the viewing window 6. Although the liquid level change in the recycling bin 1 can be observed through the liquid level rod 3, it has certain limitations. It requires close observation by the staff and is generally used for accurate calculation when recording the specific liquid level in the recycling bin 1. In this case, this embodiment sets a transparent viewing window 6 on the side wall of the recycling bin 1, so that the staff can observe the liquid level in the recycling bin 1 through the viewing window 6 even from a distance. In addition, the viewing window 6 is generally set at the top of the recycling bin 1, and is not set at the bottom of the recycling bin 1. This is mainly because the material of the viewing window 6 is more fragile than the recycling bin 1 itself, and if it is damaged, it is easy to cause the oil in the recycling bin 1 to spill. Secondly, the recycling bin 1 in this invention is mainly for the purpose of temporarily storing waste oil. When the oil level in the recycling bin 1 is sufficient, it needs to be transported to the subsequent recycling process. Therefore, in this embodiment, it is not necessary to frequently monitor the real-time liquid level in the recycling bin 1. The viewing window 6 also serves as an early warning system; when the viewing window 6 can visually detect the liquid level in the recycling bin 1, it indicates that the liquid level in the recycling bin 1 is about to reach the predetermined capacity.

[0035] Preferably, in this embodiment, a second scale line 7 is provided on the side of the viewing window 6 on the recovery tank 1. The liquid level at the position of the viewing window 6 can be directly displayed through the second scale line 7. Combined with the first scale line on the liquid level rod 3, the specific liquid level of the oil in the recovery tank 1 can be accurately calculated. In addition, since the second scale line 7 on the viewing window 6 is fixed and does not change, the liquid level rod 3 and the float 5 can be judged based on the second scale line 7 to determine whether they are malfunctioning. When the difference between the liquid level data read by the first scale line and the second scale line 7 is too large, it indicates that the liquid level rod 3 and the float 5 are malfunctioning. The cause of the malfunction may be that the liquid level rod 3 cannot slide up and down, or that the float 5 is damaged or broken and cannot provide buoyancy, etc. The corresponding faulty facilities can be repaired or replaced according to the cause of the malfunction. As long as the difference between the liquid level data read by the first scale line and the second scale line 7 is within a certain error range, there are no faulty facilities on the surface.

[0036] Preferably, in this embodiment, the float 5 is a cylindrical structure with a flat bottom, and the level rod 3 is fixed at the axis of the float 5. The flat bottom of the float 5 reduces its draft, making the level observation data more accurate. Fixing the level rod 3 at the axis of the float 5 concentrates the buoyancy of the float 5 onto the level rod 3, preventing uneven force distribution and avoiding the float 5 from tilting easily.

[0037] Preferably, in this embodiment, the level rod 3 is set on the axis of the valve seat 2, which improves the overall aesthetics and facilitates the insertion of the level rod 3 and the float ball 5 during the assembly process.

[0038] Preferably, in this embodiment, according to Figure 4 As shown, a limiting plate 4 is also fixed to the top of the liquid level rod 3. The limiting plate 4 restricts the liquid level rod 3 to prevent it from falling into the recycling tank 1 when the liquid level is low.
