Description

Technical Field

[0001] The utility model relates to the technical field of oil unloading devices, and particularly relates to an intelligent closed oil unloading device. Background Art

[0002] Oil is one of the important energy sources for industrial and agricultural production. On the one hand, there is an imbalance between oil production areas and sales areas. On the other hand, the demand for energy mainly based on oil is increasing, resulting in an upward trend in the transportation volume of oil. Currently, during the production process of oil tank trucks pulling oil in the petroleum, petrochemical, and chemical industries across the country, the vast majority of sites still adopt the traditional open oil unloading method. The open oil unloading method is a method for the oil receiving party to prevent cheating. When unloading oil openly, on-site managers observe the quality of the oil by naked eyes to check whether there is water or impurities in the oil to avoid causing major economic losses.

[0003] Since a refinery with a production capacity of over one million tons has dozens or even hundreds of oil unloading ports, due to the fact that on-site managers cannot take care of everything or other human factors, it is difficult to avoid cheating behaviors such as water and impurity mixing. Moreover, the open oil unloading method itself has many drawbacks. First, the volatile oil and gas during open oil unloading are prone to cause deflagration and result in safety accidents. Second, open oil unloading causes the crude oil to splash out, resulting in environmental pollution and air pollution. In some oil unloading platform sites, the working environment is harsh, and workers are extremely prone to getting sick after long-term inhalation of harmful substances. Third, the oil unloading speed is slow, reducing the oil unloading production efficiency. Fourth, using multiple people to supervise the quality of the oil on-site wastes manpower and material resources. According to the patent publication number CN210000944U, an intelligent closed oil unloading device is disclosed, which includes an oil inlet interface, a spherical sealing cover, an oil unloading pipe, a radio frequency water content analyzer, a butterfly valve, a bottom-mounted static electricity and overflow protector, an upper cover of the box body, an observation port cover plate, a handle, a first filter screen, a second filter screen, a sealing strip, an oil unloading port, and a speed control valve. The beneficial effects of the utility model are as follows: The spherical sealing cover facilitates effectively controlling the speed of oil inlet and the transportation volume, and prevents the oil from generating violent friction with the inner wall. The bottom-mounted static electricity and overflow protector effectively prevent static electricity during transportation and ensure the tightness of the transportation process. The observation port cover plate facilitates real-time monitoring of the situation inside the box body and prevents it from being damaged due to excessive rotation angle. The first filter screen and the second filter screen together ensure the quality of oil unloading. The sealing strip prevents the upper cover of the box body from shaking. The speed control valve effectively controls the oil output rate to prevent the oil output rate from being too fast and causing unnecessary economic losses. There are the following problems with the prior art:

[0004] In the above-mentioned publication number CN210000944U, the filtering structure is relatively single, and during long-term use, there are a large number of impurities on the surface of the filtering device, resulting in troublesome disassembly and inconvenience, thus causing problems such as being inconvenient to clean or replace the filtering device.

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0026] As Figure 1 shown, the present utility model provides an intelligent closed oil unloading device, including a tank body 1. Mounting covers 6 are arranged on both the left and right sides of the tank body 1. Circular openings communicating left and right are provided in the middle of the left and right mounting covers 6. The left side of the right mounting cover 6 is fixedly connected to the right side of the tank body 1. The inner wall of the circular opening in the right mounting cover 6 is fixedly connected to a first oil inlet pipe 2. The right side of the outer surface of the first oil inlet pipe 2 is fixedly connected to a connecting pipe 3. The right side of the inner wall of the connecting pipe 3 is fixedly connected to a second oil inlet pipe 4. The inner wall of the circular opening in the left mounting cover 6 is fixedly connected to an oil discharge pipe 5. A speed control valve is arranged on the outer surface of the oil discharge pipe 5. An intelligent valve 7 is arranged on the right side of the outer surface of the connecting pipe 3. A radio frequency water content analyzer 8 is fixedly connected through the left side of the outer surface of the connecting pipe 3;

[0027] When in use, first, the operator connects the oil delivery device to the second oil inlet pipe 4, and through the control of the intelligent valve 7, oil is delivered into the interior of the tank body 1. The model of the intelligent valve 7 is EA21, and the oil discharged is filtered through its internal structure. Then, through the setting of the speed control valve in the oil discharge pipe 5, the oil output rate is effectively controlled to prevent the oil output rate from being too fast, causing unnecessary economic losses. The discharged oil enters the oil tank to complete the operation, thus facilitating the effect of oil unloading. At the same time of oil unloading, through the setting of the radio frequency water content analyzer 8, the water content in the oil can be conveniently detected. The model of the radio frequency water content analyzer 8 is FKC01-II. The intelligent valve 7 and the radio frequency water content analyzer 8 are conventional and mature technical features in the existing technical principles.

[0028] As Figure 2 - Figure 3 shown, a blocking ring 11 is fixedly connected to the right side of the inner wall of the tank body 1. A filtering assembly 12 is lapped on the inner wall of the tank body 1. A guide rod 13 is fixedly connected through the middle of the filtering assembly 12. A sealing ring 14 is lapped and tightly pressed against the left side of the inner wall of the tank body 1. On the right side of the sealing ring 14, there is a tapered column one that expands inwards. On the left side of the sealing ring 14, there is a ring-shaped extrusion block 15 lapped and tightly pressed. A hollow threaded column is fixedly connected to the left side of the ring-shaped extrusion block 15. The left side of the hollow threaded column is fixedly connected to the surface of the mounting cover 6. The outer surface of the hollow threaded column is threadedly connected to the inner wall of the tank body 1. U-shaped handles are fixedly connected to the upper and lower sides of the left side of the left mounting cover 6. The filtering assembly 12 includes two mounting rings 121. Positioning plates 122 are fixedly connected to the upper and lower sides of the opposite surfaces of the two mounting rings 121. Filter meshes 123 are fixedly connected to the left and right sides of the inner walls of the two mounting rings 121, and the mesh sizes in the filter meshes 123 are different. The middle of the right filter mesh 123 in the mounting ring 121 is fixedly connected to the right end of the guide rod 13. The left side of the left mounting ring 121 is lapped and tightly pressed against the surface of the tapered column one in the sealing ring 14;

[0029] By placing the guide rod 13 inside the tank body 1 to drive the filter assembly 12, the right mounting ring 121 contacts the blocking ring 11, thereby restricting the position. By placing the sealing ring 14 inside the tank body 1, and then inserting the hollow threaded column in the left mounting cover 6 into the tank body 1 and rotating it, the annular extrusion block 15 is driven to push the sealing ring 14 to move, so that the tapered column one in the sealing ring 14 contacts the side surface in the left mounting ring 121 for tight extrusion, thus achieving a sealing effect and being convenient for installation. Through the arrangement of meshes with different sizes in the four filter meshes 123, it is convenient to filter the impurities in the discharged oil, improving the filtering performance. When it is necessary to replace or clean the filter assembly 12, by rotating the left mounting cover 6 counterclockwise to drive the hollow column thread, it can be removed from the inside of the tank body 1. Then, take out the sealing ring 14, and by holding the guide rod 13, drive the filter assembly 12 to be removed from the inside of the tank body 1, thus facilitating the disassembly, replacement, and cleaning of the filter assembly 12.

[0030] As Figure 4 - Figure 5 shown, on the right side of the inner wall of the oil discharge pipe 5, there is a fixed connection with a sleeve 51. The outer surface diameter of the sleeve 51 is smaller than the inner wall diameter of the oil discharge pipe 5. The outer surface of the sleeve 51 is fixedly connected with a connector 52. On the right side of the connector 52, there is a tapered column two that expands inwards. The inner wall of the connector 52 is fixedly connected with a reinforcing rod, and in the middle of the reinforcing rod, there is a fixed connection with a threaded sleeve 53. The outer surface of the sleeve 51 is fixedly connected with a rubber sleeve block one 54. On the right side of the rubber sleeve block one 54, there is a tapered column three that expands inwards. A sealing assembly 55 is inserted on the outer surfaces of the connector 52, the rubber sleeve block one 54, and the threaded sleeve 53. The outer surface of the sealing assembly 55 is fixedly connected with the inner wall of the circular opening in the left mounting cover 6. The sealing assembly 55 includes a rubber sleeve block two 551. The inner wall of the rubber sleeve block two 551 abuts and is tightly pressed against the outer surface of the rubber sleeve block one 54. On the left side of the rubber sleeve block two 551, there is a fixedly connected tapered block 552 that expands outwards. On the right side of the inner wall of the rubber sleeve block two 551, there is a fixedly connected vertical rod 553. In the middle of the left side of the vertical rod 553, there is a fixedly connected fixing bolt 554. The outer surface of the fixing bolt 554 is threadedly connected with the inside of the threaded sleeve 53;

[0031] By setting the tapered column three in the connector 52, it is convenient to socket the first rubber sleeve block 54 and fix it by adhesive. Then, by inserting the first rubber sleeve block 54 into the interior of the second rubber sleeve block 551 and simultaneously rotating the left mounting cover 6, the threaded sleeve 53 and the fixing bolt 554 are threadedly connected and fixed, so as to facilitate the connection and fixation of the oil discharge pipe 5 and the left mounting cover 6. When the threaded connection is fixed, both the first rubber sleeve block 54 and the second rubber sleeve block 551 are deformed. When the first rubber sleeve block 54 enters the second rubber sleeve block 551, the second rubber sleeve block 551 is deformed and expands outwards, and the first rubber sleeve block 54 is deformed and shrunk, so that the contact area between the two is closely fitted, thus improving the sealing performance. The setting of the tapered column three in the first rubber sleeve block 54 and the tapered block 552 in the second rubber sleeve block 551 facilitates the insertion effect. When the oil discharge pipe 5 is connected to the left mounting cover 6, the left mounting cover 6 is further connected to the tank body 1.

[0032] Next, the working principle of this intelligent airtight oil unloading device will be specifically described.

[0033] By inserting the connector 52 and the first rubber sleeve block 54 into the interior of the second rubber sleeve block 551 and simultaneously rotating the left mounting cover 6, the threaded sleeve 53 and the fixing bolt 554 are threadedly connected and fixed. Through the mutual cooperation of the first rubber sleeve block 54 and the second rubber sleeve block 551, the sealing performance is improved. After connection, the guide rod 13 is placed into the interior of the tank body 1 to drive the filtering assembly 12, so that the right mounting ring 121 contacts the blocking ring 11. Then, the sealing ring 14 is placed into the interior of the tank body 1, and the hollow threaded column in the left mounting cover 6 is inserted into the interior of the tank body 1 and rotated, so as to push the sealing ring 14 to move and make the sealing ring 14 contact the side surface in the left mounting ring 121 for tight extrusion, thus achieving the sealing effect and being convenient for installation. The setting of different-sized meshes in the four filter meshes 123 facilitates the filtering treatment of impurities in the discharged oil, thus improving the filtering performance.

[0034] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
