Description

Technical Field

[0001] The present invention relates to the technical field of temporary storage tanks, and specifically to a waste mineral oil temporary storage tank. Background Art

[0002] Hazardous waste items include waste batteries, waste mineral oil, etc. Waste mineral oil is extracted and refined from petroleum, coal, and oil shale. During the processes of mining, processing, and use, due to external factors, its original physical and chemical properties have changed, and it can no longer be used. Waste mineral oil is the oil that is replaced when it can no longer be used due to being contaminated by impurities, oxidized, and affected by heat, which has changed its original physical and chemical properties; it mainly comes from the sludge and oil foot generated during petroleum extraction and refining; the sediment generated during the storage process of mineral oil; the replacement oil of machinery, power, transportation, and other equipment, as well as the oil slag and filter media during the regeneration process. According to the "National Hazardous Waste List", it belongs to hazardous waste.

[0003] If waste mineral oil is not properly treated, once a large amount of it enters the external environment, it will cause serious environmental pollution, damage the normal living environment of organisms, and have physical hazards that can cause biological dysfunction. When the soil pores are relatively large, petroleum wastewater can also penetrate into the soil layer and pollute shallow groundwater; therefore, there is an urgent need to design a temporary storage tank for storing and containing waste mineral oil.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the invention.

[0042] Please refer to Figure 1-2 , the invention provides a temporary storage tank for waste mineral oil, including a container cabin 1a. The inner cavity of the container cabin 1a is separated by a partition into a storage cabin 2a on the left and an emergency supplies cabin 3a on the right. A plurality of anti-seepage trays 4a are arranged in the storage cabin 2a in an array. Waste mineral oil barrels 5a are placed on the anti-seepage trays 4a. The anti-seepage trays 4a are mainly used to hold the mineral oil barrels 5a and collect the waste mineral oil that may leak from the mineral oil barrels 5a. A sliding cabin door 6a is arranged on the front of the storage cabin 2a. The sliding cabin door 6a can be opened single - leaf, which is convenient for transporting the waste mineral oil barrels 5a. An intelligent access control 7a is arranged on the side of the emergency supplies cabin 3a, which is convenient for controlling the entry and exit of management personnel;

[0043] Inside the storage compartment 2a, there are a monitoring camera 8a, a constant temperature air conditioner 9a, and a disinfection facility cabinet 10a. On the disinfection facility cabinet 10a, there is a vacuum extraction leak liquid machine 11a and a hazardous waste liquid collection dish rack 12a, which are used to extract the permeated liquid collected by the anti-seepage tray 4a. The hazardous waste liquid collection dish rack 12a is used to place the hazardous waste liquid collection dish. Inside the emergency supplies compartment 3a, there is an emergency supplies shelf 13a and an equipment placement table 14a. On the equipment placement table 14a, there are a label printer 15a, a coding gun 16a, and an operation tablet computer 17a. On the top inside the storage compartment 2a, there is a smoke alarm 18a, which is used to monitor internal fires or the generation of hazardous waste item fumes. On the top outside the storage compartment 2a and the emergency supplies compartment 3a, there is a non-powered ventilation ball 19a, which is used to maintain good ventilation conditions, control the temporary storage environment of the temporary storage compartment, and suppress potential safety hazards brought by external environmental factors.

[0044] Please refer to Figure 3-6 , the anti-seepage tray 4a includes a tray main body 1 and a grate plate 2 covering the tray main body 1. After the grate plate 2 is lifted upward, it can naturally separate from the tray main body 1. At the upper end of the side wall of the tray main body 1, there is a limiting step 13 for bearing the grate plate 2. After the grate plate 2 covers the tray main body 1, it is supported, limited, and fixed by the limiting step 13 and the surrounding wall structure;

[0045] On the top surface of the grate plate 2, leakage holes 21 are arranged in an array distribution, and grid-shaped diversion grooves 22 are arranged between the leakage holes 21, which are convenient for timely and rapid diversion and collection of the permeated liquid, avoiding long-term and large-scale retention of the permeated liquid on the grate plate 2 and polluting the environment. On the back of the grate plate 2, there are two diagonally intersecting reinforcing rib plates 23, which are used to enhance the load-bearing capacity. At the intersection point of the two reinforcing rib plates 23, there is a contact column 24 that abuts against the top detection end of the pressure weighing sensor 3, ensuring good contact with the pressure weighing sensor 3;

[0046] In the middle of the inner cavity of the tray main body 1, a support column 11 protrudes and rises. At the top of the support column 11, a pressure weighing sensor 3 is embedded and installed. The top detection end of the pressure weighing sensor 3 abuts against the bottom of the grate plate 2. After the hazardous waste item is placed on the grate plate 2, its weight is transmitted to the pressure weighing sensor 3 through the grate plate 2. The wire of the pressure weighing sensor 3 is led out through the inner cavity of the support column 11 and the bottom of the tray main body 1 and connected to an external computer or controller device, and then the current weight of the hazardous waste item can be displayed, which is convenient for recording and controlling the weight change items of the hazardous waste item;

[0047] A drain pipe 12 is provided at the lower end of one side wall of the tray main body 1. The outer end of the drain pipe 12 is connected with a metering solenoid valve 4. The metering solenoid valve 4 is actually a solenoid valve and a metering valve connected in series as a whole. The solenoid valve has a manual operation handle, which can realize the electric or manual switch of the valve of the drain pipe 12 and the metering of the discharged liquid. The control circuit of the metering solenoid valve 4 is also connected with an external computer or controller device, so that the discharge amount of the penetrant can be counted, and it is convenient to record and control the discharge amount item of the penetrant;

[0048] A liquid level indicator 5 is provided on one side of the front of the tray main body 1. The liquid level indicator 5 includes a glass tube 51. Both ends of the glass tube 51 are communicated with the upper and lower sides of the tray main body 1 through flexible rubber hoses 52. A liquid level scale line 53 is provided on the front of the glass tube 51. Since the upper and lower ends of the glass tube 51 are communicated with the inner cavity of the tray main body 1, when the liquid level in the inner cavity of the tray main body 1 rises, the current liquid level position can be accurately known through the liquid level scale line 53. Further, for more intuitive observation of the liquid level change, a round piece float 54 is provided in the inner cavity of the glass tube 51. The round piece float 54 will move up and down with the rise and fall of the liquid level based on buoyancy. The round piece float 54 is painted with a bright paint with phosphor powder, which is not only more conspicuous during the day, but also easier to observe in dim light. An RFID tag 6 is attached to the top of the front of the tray main body 1; it can be used to record and mark the information of hazardous waste items, and it is convenient to record and control items such as the type and attributes of hazardous waste.

[0049] Please refer to Figure 7-8 , the waste mineral oil drum 5a includes an oil drum body 100. A barrel neck 200 is provided at the center of the top of the oil drum body 100. A sealed barrel cover 300 is provided on the barrel neck 200. A breather neck 400 is provided on the shoulder side of the top of the oil drum body 100. An orifice adjustment end cover 500 is provided on the breather neck 400. A float measuring device 600 is provided in the inner cavity of the barrel neck 200;

[0050] Specifically, the oil drum body 100 can be made of corrosion-resistant non-metallic materials. One or more grooves can be provided on the barrel body of the oil drum body 100, and the bottom can be designed as a concave structure to play a role in strengthening the structure. A corresponding sealing gasket is provided inside the sealed barrel cover 300. After the sealed barrel cover 300 is closed, reliable sealing can be ensured.

[0051] Specifically, such as Figure 9-13As shown in the figure, a breathing membrane clamping tube 410 is threadedly connected to the inner side of the port of the breathing tube neck 400. A sealing rubber ring 480 is arranged between the outer step surface of the breathing membrane clamping tube 410 and the top surface of the breathing tube neck 400 to ensure a sealed connection. The breathing membrane clamping tube 410 is a two-stage stepped tube with a larger upper part and a smaller lower part. A blocking partition 411 is provided at the inner cavity step surface of the breathing membrane clamping tube 410. A fixed breathing port 412 is opened on the blocking partition 411. The aperture adjusting end cover 500 is rotatably embedded at the upper end of the breathing membrane clamping tube 410. The aperture adjusting end cover 500 is a socketed flat cylinder with a larger upper part and a smaller lower part. A plurality of end cover limiting bumps 460 are circumferentially arranged at the upper end of the inner wall of the breathing membrane clamping tube 410. A limiting annular groove 520 matching with the end cover limiting bumps 460 is opened at the peripheral edge of the small-diameter end of the aperture adjusting end cover 500. And a damping rubber ring 470 is padded between the bottom end surface of the aperture adjusting end cover 500 and the inner step surface of the breathing membrane clamping tube 410. When the aperture adjusting end cover 500 is installed, it is directly buckled into the top tube orifice of the breathing membrane clamping tube 410. The cooperation of the plurality of end cover limiting bumps 460 and the limiting annular groove 520 is used to prevent falling off. Due to the existence of the damping rubber ring 470, it can be ensured that the aperture adjusting end cover 500 is not loose, and it has a certain damping when rotating and can hover in any orientation. Anti-slip lines are arranged on the outer edge of the aperture adjusting end cover 500 to facilitate the rotation of the aperture adjusting end cover 500; an adjusting breathing port 510 identical to the fixed breathing port 412 is opened on the aperture adjusting end cover 500. As Figure 11-12 shown, both the fixed breathing port 412 and the adjusting breathing port 510 are fan-shaped openings distributed in a circumferential array of three groups, and the fan angle of the fan-shaped opening is 60 degrees. In actual use, according to the attributes of the waste mineral oil contained, the overlapping angle range between the adjusting breathing port 510 and the fixed breathing port 412 can be changed by rotating the aperture adjusting end cover 500, and thus the size of the effective ventilation orifice can be changed. On the premise of meeting the ventilation and breathing efficiency and avoiding the increase of the pressure inside the barrel, the ventilation orifice is reduced as much as possible to inhibit the overflow of harmful gases.

[0052] Specifically, as Figure 9-13As shown in the figure, a breathable respiratory membrane 420 is arranged in the inner cavity of the respiratory membrane clamping tube 410. The breathable respiratory membrane 420 can be a conventional waterproof and breathable membrane. The breathable respiratory membrane 420 is located below the blocking partition 411. An inner sleeve 430 is nested below the breathable respiratory membrane 420 in the inner cavity of the respiratory membrane clamping tube 410. A cross frame 431 is integrally arranged on the inner cavity wall of the inner sleeve 430. Inner sleeve limiting bumps 413 are arranged in a circumferential array at the lower end of the inner cavity wall of the respiratory membrane clamping tube 410. Two wave springs 440 are arranged between the blocking partition 411 and the inner sleeve 430. The two wave springs 440 are located on the upper and lower sides of the breathable respiratory membrane 420. A funnel grate plate 450 is fixedly arranged on the inner cavity side wall of the respiratory tube neck 400. A conical boss 451 bulges upward in the center of the funnel grate plate 450. After the respiratory membrane clamping tube 410 and the respiratory tube neck 400 are screwed together, the conical boss 451 can support the inner sleeve 430 to clamp the breathable respiratory membrane 420 tightly. A plurality of ventilation slots 452 are arranged in a circumferential array on the conical surface of the conical boss 451. As Figure 4 As shown in the figure, when the breathable respiratory membrane 420 is actually installed, first invert the respiratory membrane clamping tube 410, put in a wave spring 440, then put in the breathable respiratory membrane 420, put in the second wave spring 440, and finally snap in the inner sleeve 430. The inner sleeve 430 is blocked by a plurality of inner sleeve limiting bumps 413 at the edge of the end face of the inner sleeve 430, so as to prevent the inner sleeve 430 from naturally separating from the respiratory membrane clamping tube 410. In this way, the respiratory membrane clamping tube 410 can be inverted and erected and then screwed to the respiratory tube neck 400. After the respiratory membrane clamping tube 410 and the respiratory tube neck 400 are screwed together, the conical boss 451 can support the inner sleeve 430 to clamp the breathable respiratory membrane 420 tightly. The breathable respiratory membrane 420 can be arranged in a relaxed state in the inner cavity of the respiratory membrane clamping tube 410 through the cooperation of the inner sleeve 430 and the inner sleeve limiting bumps 413. During the actual use of the breathable respiratory membrane 420, it will block and adhere to dust and soak up oil and gas. Therefore, it needs to be replaced regularly. During the actual replacement operation, directly unscrew and disassemble the respiratory membrane clamping tube 410 together with the breathable respiratory membrane 420 and the inner sleeve 430 in the reverse direction, and then extract the inner sleeve 430 through the cross frame 431 to remove the internal breathable respiratory membrane 420 for replacement, without picking it out in the respiratory tube neck 400. The replacement is convenient and the operation difficulty is low.

[0053] As Figure 14As shown, the buoy measurement device 600 includes a buoy rod sleeve 610. The outer wall of the buoy rod sleeve 610 is fixedly installed with the side wall of the barrel neck 200 through an integrally provided sleeve boss 620. A buoy rod body 630 is movably sleeved in the inner cavity of the buoy rod sleeve 610. A hollow buoy 640 is connected to the lower end of the buoy rod body 630. A liquid level indication scale 650 is provided on the outer wall of the buoy rod body 630. In the buoy measurement device 600, after the hollow buoy 640 is filled with oil, it will drive the buoy rod body 630 to rise as the oil liquid level rises. By observing the liquid level indication scale 650 on the buoy rod body 630, the state of the internal oil liquid level can be accurately and directly known, which is convenient for controlling the actual storage volume, so as to consider safety factors and control the corresponding spare storage space. Therefore, waste mineral oils of different category specifications and required different spare storage spaces can all be contained in this unified mineral oil barrel, which is convenient for unified management of the equipment; further, the upper end of the inner hole of the buoy rod sleeve 610 is an internal thread stepped hole 660, and an external thread stepped column 670 that can be screwed and matched with the internal thread stepped hole 660 is connected to the upper end of the buoy rod body 630. A screwing vertical plate 680 is provided on the top surface of the external thread stepped column 670. Further, since the buoy rod body 630 will change with the liquid level, after the oil is filled or when the oil is poured and unloaded, the external thread stepped column 670 on the buoy rod body 630 can be screwed and fixed with the internal thread stepped hole 660 to prevent the buoy rod body 630 from protruding out of the barrel neck 200, thereby not hindering the closing of the sealing barrel cover 300 and the operation of pouring and unloading oil.
