Description

Technical Field

[0001] This utility model relates to the field of waste mineral oil processing and storage technology, and in particular to a temporary storage device for waste mineral oil processing. Background Technology

[0002] Temporary storage devices not only serve as temporary storage for waste mineral oil, but also need to simultaneously perform pre-treatment operations such as impurity pre-filtration, which directly affects the efficiency of subsequent deep processing. With the upgrading of the "Pollution Control Standard for Hazardous Waste Storage" to "prevent leakage and volatilization" and the need for enterprises to reduce costs and increase efficiency, convenient maintenance is the key to ensuring equipment operation and controlling costs in the temporary storage of waste mineral oil. Waste mineral oil contains impurities that can easily clog filter media. If maintenance is not timely, it will reduce filtration efficiency and clog pipelines. Moreover, the devices are mostly deployed in peripheral areas with limited maintenance conditions. Waste mineral oil is hazardous waste and needs to be protected against volatilization and leakage. Therefore, "no need to dismantle the tank, quick filter media replacement, and no loss of seal after maintenance" are the core requirements.

[0003] However, existing devices have shortcomings in terms of convenient maintenance. The filter media are mostly bolted, deeply embedded, or integrated with the baffle plate. The operating space inside the tank is small and the light is poor, which makes it easy for bolts to strip and parts to fall off. Each replacement takes a long time. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a temporary storage device for waste mineral oil processing, which can solve the problem of cumbersome filter material replacement in temporary storage devices for waste mineral oil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temporary storage device for waste mineral oil processing, comprising a storage tank, a support leg fixedly connected to the lower surface of the storage tank, a feed pipe fixedly connected to the upper surface of the storage tank, a feed valve fixedly connected to the outer wall of the feed pipe, a threaded port fixedly connected to the upper surface of the storage tank, a tank cover threadedly fitted to the outer wall of the threaded port, a clean oil scale pipe and a waste oil scale pipe fixedly connected to the outer wall of the storage tank, a discharge pipe fixedly connected to the lower surface of the storage tank, a discharge valve fixedly connected to the outer wall of the discharge pipe, a guide plate fixedly connected to the inner wall of the storage tank, a retaining ring fixedly connected to the discharge port of the guide plate, a retaining ring slidably connected to the inner wall of the retaining ring, a filter box threadedly fitted to the outer wall of the retaining ring, filter media placed inside the filter box, a connecting rod fixedly connected to the inner wall of the retaining ring, a rope fixedly fitted to the outer wall of the connecting rod, and a stop rod fixedly fitted to the end of the rope not connected to the connecting rod.

[0006] Preferably, the feed pipe extends into the interior of the storage tank, the discharge pipe extends into the interior of the storage tank, and both ends of the clean oil scale pipe and the waste oil scale pipe extend into the interior of the storage tank.

[0008] Preferably, the upper surface of the retaining ring is fixedly connected to two sliding rods, and the outer wall of the retaining ring is fixedly connected to two limiting sliders.

[0009] Preferably, the upper surfaces of the two slide bars are fixedly connected to the inner upper wall of the storage tank, the two limiting sliders are in contact with the retaining ring, the two limiting sliders are slidably connected to the corresponding slide bars, and the filter box is slidably connected to the retaining ring.

[0010] Preferably, both the clean oil scale tube and the waste oil scale tube are horizontal "U" shaped, and the limiting slider is "C" shaped.

[0011] Preferably, the outer wall of the filter box is provided with a plurality of filter holes, which are evenly distributed on the side wall and bottom of the filter box, and the pore diameter is smaller than the particle diameter of the filter material.

[0014] Preferably, the length of the stop bar is greater than the inner diameter of the threaded opening.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The temporary storage device for waste mineral oil processing can be operated by unscrewing the tank cover and pulling the connecting rod with the rope by holding the stop bar. This will cause the limit slider to slide upward along the slide bar, so that the retaining ring is disengaged from the retaining ring and the filter box can be taken out directly from the threaded end. The whole process does not require entering the narrow space inside the tank to operate, avoiding problems such as bolt stripping and parts falling off. The time for replacing the filter material once is shorter than that of traditional devices, and there is no need to disassemble the main structure of the tank, which shortens the downtime and improves the work efficiency.

[0017] (2) The temporary storage device for waste mineral oil processing is connected to the lower cleaning oil area of ​​the storage tank through the cleaning oil scale tube, which can observe the cleaning oil level in real time. When discharging, the opening of the discharge valve is adjusted by the change of the liquid level to avoid excessive discharge or residue of cleaning oil. The waste oil scale tube is connected to the upper waste mineral oil temporary storage area of ​​the storage tank, which can monitor the total amount of injected waste mineral oil to prevent over-storage. It can also intuitively judge whether the filter material is clogged or ineffective by the linkage change of "continuous rise of waste oil level and slow increase of cleaning oil level". The internal filtration status can be grasped without disassembling the device, providing an accurate basis for filter material replacement and avoiding efficiency waste or safety risks caused by blind maintenance.

[0031] A guide plate 10 is fixedly connected to the inner wall of storage tank 1. A retaining ring 19 is fixedly connected to the outlet of the guide plate 10. Two sliding rods 11 are fixedly connected to the upper surface of the retaining ring 19. The upper surfaces of the two sliding rods 11 are fixedly connected to the inner upper wall of storage tank 1. A retaining ring 18 is slidably connected to the inner wall of the retaining ring 19. Two limiting sliders 14 are fixedly connected to the outer wall of the retaining ring 18. The two limiting sliders 14 are in contact with the retaining ring 19. The limiting sliders 14 are C-shaped. The limiting slider 14 is slidably connected to the corresponding sliding rod 11. The outer wall of the retaining ring 18 is threaded with a filter box 16. The filter box 16 is slidably connected to the retaining ring 19. The filter material 15 is placed inside the filter box 16. The inner wall of the retaining ring 18 is fixedly connected with a connecting rod 12. The outer wall of the connecting rod 12 is fixedly sleeved with a rope 13. The end of the rope 13 that is not connected to the connecting rod 12 is fixedly sleeved with a stop rod 17. The inner wall of the threaded opening 20 is provided with a groove for the stop rod 17 to slide.

[0032] Working principle:

[0033] First, ensure that the tank cover 3 is tightened and sealed, and the discharge valve 7 is closed. Open the feed valve 5 to allow waste mineral oil to be injected into the storage tank 1 through the feed pipe 4. The oil is guided to the filter box 16 through the guide plate 10. After impurities are filtered by the internal filter material 15, the clean oil flows into the lower storage area of ​​the tank. At the same time, the clean oil level is monitored by the horizontal "U"-shaped clean oil scale tube 8, and the total feed amount and filter material blockage are monitored by the waste oil scale tube 9. When the clean oil level reaches the required level, slowly open the discharge valve 7. Observe the liquid level through the clean oil scale tube 8 and adjust the discharge flow rate. After the liquid level drops to the target value, close the discharge valve 7 to complete the discharge operation.

[0034] When the level in the clear oil graduated tube 8 rises slowly, the discharged clear oil becomes turbid, or the level in the waste oil graduated tube 9 continues to rise, the filter material 15 is deemed to be faulty. Drain the waste mineral oil from the tank, unscrew the tank cover 3, hold the stop lever 17 and pull the connecting rod 12 through the rope 13, causing the limit slider 14 to move upward along the slide rod 11 and disengage from the retaining ring 19. Take out the filter box from the threaded opening 20, separate the filter box 16 from the retaining ring 18 by threads, replace with new filter material, reconnect, and then put the filter box back along the slide rod 11 so that the retaining ring 18 is engaged with the retaining ring 19. Tighten the tank cover 3 to restore its use.

[0035] By unscrewing the tank cover 3 and pulling the connecting rod 12 via the rope 13 using the hand stop 17, the limiting slider 14 can be moved upward along the sliding rod 11, causing the retaining ring 18 to disengage from the retaining ring 19, and the filter box 16 can be directly removed from the threaded opening 20. The entire process does not require entering the narrow space inside the tank, avoiding problems such as stripped bolts and falling parts. The time for a single filter material replacement is shortened compared to traditional devices, and there is no need to disassemble the main structure of the tank, reducing downtime and improving work efficiency.

[0036] The clean oil level is connected to the lower clean oil zone of the storage tank 1 via the clean oil scale tube 8, allowing real-time observation of the clean oil level. During discharge, the opening of the discharge valve 7 is adjusted based on the change in the oil level to prevent excessive discharge or residue of clean oil. The waste oil scale tube 9 is connected to the upper waste mineral oil storage zone of the storage tank 1, which can monitor the total amount of injected waste mineral oil to prevent over-storage. It can also visually determine whether the filter media 15 is clogged or ineffective by observing the linkage between the continuous rise in waste oil level and the slow increase in clean oil level. The internal filtration status can be grasped without disassembling the device, providing an accurate basis for filter media replacement and avoiding inefficiency waste or safety risks caused by blind maintenance.
