Description

Technical Field

[0001] This utility model relates to the field of storage and transportation equipment technology, and specifically discloses an oil depot tank. Background Technology

[0002] In underground mining operations, emulsions and other oils are typically transported in drums, using metal or plastic drums for loading and transfer. However, this traditional method has the following problems:

[0003] Environmental issues are prominent, with a large number of waste oil drums generated every year (such as about 960 drums per year at Zhangcun Coal Mine), requiring additional high costs for waste drum disposal (about 146,000 yuan per year).

[0004] Accumulated waste barrels can easily lead to grease leaks, polluting the soil and groundwater, and open-air storage poses a risk of high-temperature explosion and combustion.

[0005] Low transportation and storage efficiency, frequent loading and unloading of barrels, and small single transport volume (only 0.2 tons per barrel) result in high transportation costs (e.g., 192,000 yuan per year for a monorail crane).

[0006] Oil drums are stacked, taking up a large amount of warehouse space, and multi-layer stacking can easily cause tipping accidents;

[0007] Safety and maintenance hazards: poor sealing of oil drums makes them prone to leakage during transportation, which can affect the normal operation of downhole equipment.

[0008] Currently, some mines are trying to use fixed storage tanks to replace drums, but most of the existing tanks are vertical structures, which cannot adapt to transportation in narrow underground tunnels, and lack anti-sway and anti-leakage designs, making it difficult to meet the needs of underground working conditions.

[0009] Therefore, there is an urgent need for a special oil tank for underground oil transfer, which can solve the environmental and economic drawbacks of drum packaging while ensuring transportation safety. Utility Model Content

[0010] This utility model proposes an oil storage tank for grease, which solves the environmental pollution problem caused by waste oil drums by changing the transportation of emulsions from drums to tanks, saving the annual disposal costs of waste oil drums, realizing recycling, reducing the number of times they are used, improving downhole production efficiency, and ensuring the purity of grease and the safety of transportation and storage through optimized structure, reducing the risk of leakage and explosion, and saving about 450,000 yuan per year.

[0011] This utility model is implemented as follows: an oil storage tank includes a horizontally arranged tank body, which comprises a cylindrical section in the middle and hemispherical end caps at both ends; the top of the tank body is provided with at least one oil inlet, and one end of the bottom is provided with an oil outlet with a control valve; two saddle supports are fixedly connected to the bottom of the tank body, and the arc-shaped support surface of the saddle supports is fully welded to the outer wall of the tank body, the saddle supports are used to adapt to the uneven support surface of the underground roadway; at least two baffles are provided inside the tank body, the baffles are vertically welded to the inner wall of the tank body and divide the inner cavity into multiple compartments, the baffles are used to suppress the shaking and impact during the transportation of oil.

[0012] As a preferred embodiment of the oil storage tank of this utility model, the oil inlet is equipped with a sealing end cap, the sealing end cap is threadedly connected to the oil inlet and a sealing ring is provided between the two.

[0013] As a preferred embodiment of the oil storage tank of this utility model, a protective bracket is provided on the outside of the oil outlet. The protective bracket is a three-dimensional frame structure surrounding the oil outlet, and the oil outlet is connected to a quick connector.

[0014] As a preferred embodiment of the oil storage tank of this utility model, the top of the tank is provided with a liquid level observation window and an explosion-proof breathing valve.

[0015] As a preferred embodiment of the oil storage tank of this utility model, the baffle plate has a flow guide hole at the bottom and a vent hole at the top.

[0016] As a preferred embodiment of the oil storage tank of this utility model, the inner wall of the tank is coated with an anti-corrosion coating.

[0017] As a preferred embodiment of the grease storage tank of this utility model, a detachable filter screen is provided on the inner side of the oil inlet.

[0018] The beneficial effects of this utility model are:

[0019] 1. The tank replaces the traditional oil drum, reducing the generation and disposal costs of waste oil drums, avoiding pollution from waste oil leaks, and meeting national requirements for the storage of hazardous chemicals and environmental protection; it reduces the costs of purchasing new oil drums, disposing of waste oil drums, and manual transportation, and the oil tank can be recycled for many years, resulting in significant long-term cost savings; moreover, the amount of oil transported at one time is increased, reducing the number of times it needs to be used and the frequency of transportation, which is suitable for the high-efficiency production rhythm of underground wells; through the design of baffles, explosion-proof breathing valves, protective supports, etc., the risk of shaking and impact, explosion and equipment damage during transportation are reduced.

[0020] 2. The sealing structure and anti-corrosion coating prevent impurities and moisture from entering, ensuring the purity of the grease and avoiding affecting the safe operation of underground equipment. The structural design is adapted to the underground roadway space, and the saddle support adapts to complex terrain, meeting the needs of special mining operating environments.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-3 The oil storage tank includes a horizontally arranged tank body 1, which includes a cylindrical section in the middle and hemispherical heads at both ends. The top of the tank body 1 is provided with at least one oil inlet 2, and the bottom of one end is provided with an oil outlet 4 with a control valve 3. Two saddle supports 5 are fixedly connected to the bottom of the tank body 1. The arc-shaped support surface of the saddle support 5 is fully welded to the outer wall of the tank body 1. The saddle support 5 is used to adapt to the uneven support surface of the underground roadway. The tank body 1 is provided with at least two baffles 6. The baffles 6 are vertically welded to the inner wall of the tank body 1 and divide the inner cavity into multiple compartments. The baffles 6 are used to suppress the shaking and impact during the transportation of oil.

[0028] In this embodiment: the tank body 1 consists of a central cylindrical section and hemispherical end caps at both ends. This structure provides a regular and pressure-resistant space for grease storage, and the hemispherical end caps enhance the end sealing and structural strength, allowing the tank body to have a larger volume to store sufficient grease. The top oil inlet 2 is used to introduce grease (the number can be set as needed to meet different oil filling efficiency requirements); the bottom oil outlet 4 is equipped with a control valve 3, which can accurately control the grease flow, realize on-demand discharge, avoid random leakage or excessive flow of grease, and ensure the controllability of grease access. Two saddle supports 5 are fixed to the bottom of the tank body 1, and their arc-shaped support surfaces are fully welded to the outer wall of the tank body 1, which can stably support the grease. The weight of tank 1 is evenly distributed to the supporting foundation. On the other hand, the close-fitting welding method enhances the stability of the connection between tank 1 and the support, allowing the oil tank to remain stable when placed (such as on the ground, transport carrier, etc.) and adapt to the load-bearing requirements of different sites. The baffle plate 6 is vertically welded to the inner wall of tank 1, dividing the inner cavity into multiple compartments. When the oil tank is transported or shaken, the baffle plate 6 can prevent the oil from surging, reduce the impact of liquid sloshing on tank 1, and reduce the risk of wear and deformation caused by oil sloshing. At the same time, the multiple compartments also make the oil storage more orderly. Even if there is local shaking, the impact range is limited by the compartment division, which improves the overall structural stability.

[0029] As a technical optimization of this utility model, the oil inlet 2 is equipped with a sealing end cap 7, which is threadedly connected to the oil inlet 2 and a sealing ring 8 is provided between them.

[0030] In this embodiment: the sealing end cap 7 enhances the sealing performance of the oil inlet 2, the threaded connection facilitates the opening and closing of the end cap, and the sealing ring 8 fills the gap, effectively preventing external impurities and moisture from entering the tank and contaminating the grease, and also preventing grease leakage from the tank, thus ensuring the quality of grease storage and environmental cleanliness.

[0031] As a technical optimization of this utility model, a protective bracket 9 is provided on the outside of the oil outlet 4. The protective bracket 9 is a three-dimensional frame structure that surrounds the oil outlet 4, and the oil outlet 4 is connected to a quick connector 10.

[0032] In this embodiment: the protective bracket 9 protects the oil outlet 4 and connecting components from damage caused by external forces such as collision and squeezing, and extends the life of components such as the oil outlet 4 and control valve 3; the quick connector 10 makes it more convenient and efficient to connect the oil outlet 4 to the oil pipeline, improves the efficiency of oil output operation, and meets the needs of quick connection in production.

[0033] As a technical optimization of this utility model, the top of the tank body 1 is provided with a liquid level observation window 11 and an explosion-proof breathing valve 12.

[0034] In this embodiment: the liquid level observation window 11 allows the operator to visually view the oil level in the tank, making it easier to grasp the storage volume and rationally arrange oil injection or use; the explosion-proof breathing valve 12 balances the air pressure inside and outside the tank, avoiding abnormal air pressure inside the tank due to temperature changes or oil entering and leaving, preventing dangers such as tank deformation and explosion, and improving the safety performance of the oil tank.

[0035] As a technical optimization of this utility model, the wave deflector 6 has a flow guide hole 13 at the bottom and a ventilation hole 14 at the top.

[0036] In this embodiment: the guide hole 13 allows the oil between the compartments to flow moderately, avoiding the impact of oil stratification or local accumulation on storage and output due to oil standing still; the vent hole 14 balances the air pressure between the compartments, preventing excessive air pressure difference in the compartments due to oil sloshing, temperature changes, etc., so that while the baffle plate 6 separates the compartments, it ensures the stability of the oil storage environment and enhances the positive effect of the baffle plate 6 on the overall stability of the oil tank.

[0037] As a technical optimization of this utility model, the inner wall of the tank body 1 is coated with an anti-corrosion coating 15.

[0038] In this embodiment: the anti-corrosion coating 15 can isolate the metal inner wall of the tank 1 from grease, air, etc., to prevent the tank 1 from being damaged by corrosion and extend the service life of the oil tank; it can also prevent corrosion products of the tank 1 from mixing into the grease, ensuring the quality of the grease and reducing the maintenance and replacement costs and the risk of grease contamination caused by the corrosion of the tank 1.

[0039] As a technical optimization of this utility model, a detachable filter screen 16 is provided on the inner side of the oil inlet 2.

[0040] In this embodiment, the detachable filter screen 16 pre-filters the grease in the injection tank, intercepts impurities, further improves the purity of the grease in the tank, protects subsequent oil transportation and oil use equipment, reduces equipment wear and failure caused by impurities, and the detachable design makes it easy to clean and replace the filter screen, ensuring the continuous effectiveness of the filtration function.

[0041] Working principle and usage process of this utility model:

[0042] Open the sealing end cap 7 of the oil inlet 2, and inject emulsion or other grease into the tank 1 through the oil inlet 2. Observe the oil volume through the liquid level observation window 11. After reaching the preset capacity, close the sealing end cap 7 to ensure that the sealing ring 8 is in place. Transfer the oil tank to the usage location using downhole transportation equipment (such as a monorail). During transportation, the baffle 6 reduces grease sloshing, the saddle support 5 ensures the stability of the tank 1, and the explosion-proof breather valve 12 balances the internal and external air pressure to prevent abnormalities in the tank 1 due to temperature changes. After arriving at the usage location, connect the external oil pipeline through the quick connector 10 of the oil outlet 4, open the control valve 3, and the grease flows into the equipment through the oil outlet 4. The protective bracket 9 protects the oil outlet 4 from collisions to ensure smooth oil discharge. After the grease is used up, transport the oil tank back to the grease storage and repeat the above oil injection, transportation, and oil discharge process to achieve recycling.
