Description

Technical Field

[0001] This invention relates to the technical field of residual oil tank discharge equipment, specifically a semi-automatic discharge machine for efficient cleaning of residual oil tanks. Background Technology

[0002] Residual oil is the oil remaining after crude oil is frequently distilled under reduced pressure to extract gasoline, kerosene, diesel, cracked feedstock oil, or lubricating oil fractions. It has a boiling point of approximately 525℃ or higher and is a product of deep processing such as thermal cracking and catalytic cracking. It is the heavy oil remaining after the extraction of light oil products. Residual oil tanks are containers used to store residual oil and are typically made of corrosion-resistant and high-temperature-resistant materials. Currently, refineries have residual oil storage tanks with an annual capacity exceeding 300 tons. Conventional residual oil storage tanks are 2000-3000 cubic meters in size and are designed to be above the inspection manhole. Due to the characteristics of residual oil, no mechanical pump can currently extract it, relying entirely on manual labor. Manual labor faces numerous risks, including slow speed and a high risk of poisoning. Summary of the Invention

[0003] 1. Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a highly efficient semi-automatic discharge machine for cleaning residual oil tanks. The semi-automatic discharge machine is equipped with spiral discharge blades. During operation, the discharge machine uses cutting blades to crush and transport the residual oil. The residual oil enters the plastic sleeve through an automatic feed pipe, and then a reduction motor drives the transmission shaft to rotate, thereby rotating the spiral discharge blades to carry the residual oil to the automatic discharge port for extraction. This semi-automatic discharge machine adopts the tunnel boring machine principle, supplemented by minimal manual work outside the tank, significantly increasing the cleaning speed and reducing the risks associated with manual work inside the tank. This equipment can continuously clean over 80% of the residual oil in the storage tank in a single operation, solving the problems raised in the background technology.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The semi-automatic discharge machine is equipped with a geared motor. After the residual oil enters the plastic sleeve through the automatic feeding pipe, the geared motor drives the transmission shaft to rotate. The transmission shaft is fixedly connected to the spiral discharge blades. Therefore, the rotation of the spiral discharge blades conveys the residual oil to the automatic discharge port and extracts the residual oil from the residual oil tank.

[0015] 2. The semi-automatic discharge machine is equipped with a tunneling blade. The tunneling blade is connected to the drive shaft through a connecting ring. When the reduction motor drives the drive shaft to rotate, it will drive the tunneling blade to rotate, thereby crushing and conveying the slag oil.

[0016] 3. The automatic discharge pipe of the semi-automatic discharge machine is equipped with a scraper mechanism. The scraper mechanism drives the moving scraper to move by the extension and retraction of the electric push rod. The reciprocating motion of the moving scraper can clean the pipe opening of the automatic discharge pipe and prevent the pipe opening from being blocked by residue and oil.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example

[0024] Reference Figure 1-4 As shown,

[0025] A semi-automatic discharge machine for high-efficiency cleaning of residual oil tanks includes a plastic sleeve 1 arranged parallel to a horizontal plane. The plastic sleeve 1 is a cylindrical structure with both ends connected. A reduction motor 5 is installed outside one end of the plastic sleeve 1. The drive shaft of the reduction motor 5 is parallel to the horizontal plane and faces the plastic sleeve 1. The drive shaft of the reduction motor 5 is coaxially fixed to one end of a rotating shaft 6. The end of the rotating shaft 6 away from the reduction motor 5 passes through the plastic sleeve 1 and is fixedly connected to a connecting ring 7 located outside the plastic sleeve 1. Two mirror-symmetrical digging blades 701 are provided on the outer wall of the connecting ring 7. A spiral discharge blade 9 is provided inside the plastic sleeve 1. Between the end of the plastic sleeve 1 away from the geared motor 5 and the two automatic discharge pipes 102, the spiral discharge blade 9 is penetrated by the rotating shaft 6 and fixedly connected to the outer wall of the rotating shaft 6. The plastic sleeve 1 is made of 500 high-strength engineering plastic. Two mirror-symmetrical automatic discharge pipes 102 are provided on the upper and lower sides of the plastic sleeve 1. The axes of the two automatic discharge pipes 102 are located on the same vertical line. An automatic feeding pipe 101 is also provided on the upper side of the plastic sleeve 1 away from the automatic discharge pipes 102. Both the automatic feeding pipe 101 and the automatic discharge pipes 102 are connected to the plastic sleeve 1. A scraper mechanism 2 is provided on the side of the automatic discharge pipe 102 away from the plastic sleeve 1.

[0026] When the semi-automatic discharge machine is working, the operator drives the reduction motor 5, which is an explosion-proof reduction motor. The reduction motor 5 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the tunneling blade 701, which is connected to the rotating shaft 6 via a connecting ring 7, to rotate. Residual oil is typically a viscous, high-viscosity substance that is not easily flowable. The tunneling blade 701, through high-speed rotation or vibration, cuts and breaks the residual oil into smaller particles or droplets. The tunneling blade 701 stirs the residual oil within the tank, making the residual oil more evenly distributed and preventing sedimentation or stratification. This helps improve discharge efficiency and ensures the quality and uniformity of the residual oil. The rotation of the tunneling blade 701 generates a thrust that moves the residual oil, transporting it from the tank to the automatic feed pipe 101. The reduction motor 5 can adjust the rotation speed of the tunneling blade 701 to control the flow rate and conveying speed of the residual oil. This helps control the conveying efficiency and flow rate of the semi-automatic discharge machine to meet different needs and operating conditions. The rotation of the rotating shaft 6 also drives the spiral discharge blades 9 fixed on the outer wall of the rotating shaft 6 to rotate. The sludge oil enters the plastic sleeve 1 through the automatic feeding pipe 101. The plastic sleeve 1 is made of 500 high-strength engineering plastic. 500 high-strength engineering plastic has high strength and hardness, good wear resistance and excellent temperature stability. It can withstand stress under high pressure and high load conditions. In many applications, it can replace metal and is an ideal material for manufacturing high-friction parts. It can maintain its performance under high and low temperature conditions. This material can be used in the range of -40℃ to 100℃ and will not soften or deform at high temperatures. 500 high-strength engineering plastic can be processed by injection molding, extrusion molding, compression molding and other methods. The processing process is simpler and more economical and efficient than that of metal.

[0027] The rotating spiral discharge blade 9 transports the sludge oil in the plastic sleeve 1 to the automatic discharge port for discharge. The scraper mechanism 2 of the automatic discharge pipe 102 cleans the pipe opening to prevent blockage by sludge oil. The spiral discharge blade 9 is a 500° auger blade. The rotating shaft 6 and the tunneling blade 701 are made of beryllium copper alloy. Beryllium copper alloy is a type of Wuxi bronze with beryllium as the main alloying element, containing 1.7-2.5% beryllium and small amounts of nickel, chromium, titanium, etc. After quenching and aging treatment, its strength limit can reach 1250-1500 MPa, approaching the level of medium-strength steel. It has excellent plasticity in the quenched state. Beryllium bronze has high hardness, elastic limit, fatigue limit, and wear resistance, as well as good corrosion resistance, thermal conductivity, and electrical conductivity. It does not produce gas upon impact. The rotating shaft 6, made of beryllium copper alloy, is designed to meet the requirements for use in the highest-level explosion-proof environments. The semi-automatic discharge machine adopts the principle of tunnel boring machine (TBM) and is supplemented by a small amount of manual work outside the tank, effectively reducing the risk of poisoning for workers. At the same time, the semi-automatic discharge machine can increase the cleaning speed of residual oil in the tank by several times, reducing the risk of manual work inside the tank. The cleaning operation performed by the semi-automatic discharge machine can continuously clean more than 80% of the residual oil in the storage tank in one go, effectively improving the cleaning rate of residual oil in the tank.

[0028] A first connecting plate 3 and a second connecting plate 10 are fixedly installed at both ends of the plastic sleeve 1. The first connecting plate 3 is located at the end of the plastic sleeve 1 closest to the reduction motor 5, and the second connecting plate 10 is located at the end of the plastic sleeve 1 furthest from the reduction motor 5. Both the first connecting plate 3 and the second connecting plate 10 are penetrated by a rotating shaft 6. Both the first connecting plate 3 and the second connecting plate 10 are perpendicular to the horizontal plane. The axes of the plastic sleeve 1, the first connecting plate 3, and the second connecting plate 10 are located on the same horizontal line. A foldable support base 8 is provided below the second connecting plate 10. A fixed housing 4 is fixedly installed on the side of the first connecting plate 3 furthest from the plastic sleeve 1, and a fixed housing 4 is also provided on the side of the second connecting plate 10 furthest from the fixed housing 4. A cavity is opened inside the fixed housing 4. The fixed housing 4 and the axis of the plastic sleeve 1 are located on the same horizontal line. The rotating shaft 6 penetrates the two fixed housings 4. The reduction motor 5 is located on the outside of the fixed housing 4 furthest from the connecting ring 7. The reduction motor 5 is fixedly connected to the side of the fixed housing 4 furthest from the plastic sleeve 1.

[0029] The plastic sleeve 1 is provided with connecting plates at both ends, which can seal the plastic sleeve 1. A foldable support base 8 is provided below the second connecting plate 10, which can assist in supporting the semi-automatic discharge machine. The fixed housing 4 can provide a certain degree of protection for the connecting plate.

[0030] The scraper mechanism 2 includes a third connecting plate 201, an electric push rod 202, and a movable scraper 203. The third connecting plate 201 is fixedly disposed on the side of the automatic discharge pipe 102 away from the plastic sleeve 1. The electric push rod 202 is fixedly disposed on the side of the third connecting plate 201 near the reduction motor 5. The electric push rod 202 is parallel to the horizontal plane. The electric push rod 202 is fixedly connected to the movable scraper 203, which is parallel to the horizontal plane. The side of the movable scraper 203 near the automatic discharge pipe 102 is in contact with the side of the automatic discharge pipe 102 away from the plastic sleeve 1. The electric push rod 202 and the movable scraper 203 are perpendicular to each other.

[0031] The scraper mechanism 2 can clean the semi-automatic discharge port. When the scraper mechanism 2 is working, the operator drives the electric push rod 202, which extends and retracts to move the movable scraper 203. One side of the movable scraper 202 is in contact with the opening of the automatic discharge pipe 102. The movable scraper 203 reciprocates under the drive of the electric push rod 202 to clean the opening of the automatic discharge pipe 102, thereby effectively preventing the opening of the automatic discharge pipe 102 from becoming blocked.
