Description

Technical Field

[0001] The invention relates to the technical field of dehydration bins, and in particular to a petroleum coke dehydration bin. Background Art

[0002] In the process of petroleum blending, its water content and impurity content have an important impact on subsequent use. Traditional petroleum coke dehydration methods often have problems such as low efficiency, serious waste gas emission pollution, low degree of automation and low resource utilization. First, when processing petroleum coke, traditional dehydration methods often use simple filtering or drying equipment, which is easy to clog during the processing process, resulting in low dehydration efficiency and ineffective removal of fine particles and impurities in petroleum coke. This not only affects the quality of petroleum coke, but also increases the difficulty and cost of subsequent processing. Secondly, the waste gas generated by traditional dehydration equipment during the dehydration process is often directly discharged without treatment, which contains a large amount of harmful substances, posing a serious threat to the environment and human health. With the increasingly stringent environmental protection regulations, the requirements for waste gas emissions are also getting higher and higher. Traditional dehydration methods can no longer meet current environmental protection requirements. In addition, the automation degree of traditional dehydration equipment is low and requires a lot of manual operation, which not only increases labor intensity but also reduces work efficiency. At the same time, due to the complex operation of the equipment, the maintenance cost is relatively high. Finally, traditional dehydration methods often ignore the recycling of resources during the dehydration process, resulting in a large amount of powder materials and water being wasted. This not only increases production costs, but also goes against the concept of sustainable development. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a petroleum coke dehydration bin to more accurately solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0017] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-Figure 7 As shown, a petroleum coke dehydration bin proposed in one embodiment of the present invention is mainly composed of a bin body 1, and a rotatable rotating plate 2 is designed on the inner wall of the bin body 1. A plurality of filter cartridges 3 are installed on the top of the rotating plate 2, and the main function of the filter cartridge 3 is to filter the material entering the bin body 1. In order to adjust the height, a lifting ring 4 is placed on the top of the rotating plate 2, and the surface of the lifting ring 4 and the inner wall of the bin body 1 are provided with corresponding threads to realize the threaded connection between the lifting ring 4 and the bin body 1. The bin body 1 is provided with a scraper 5 on the surface of the filter cartridge 3, which is used to clean the surface of the filter cartridge 3 when the lifting ring 4 moves up and down. A filter plate 7 that can move up and down is provided at the bottom of the rotating plate 2, which is used to separate water and powder materials. A partition 13 that rotates through a bearing is provided on the top of the bin body 1, and an exhaust port 31 is designed on the top of the filter cartridge 3 to discharge exhaust gas during the dehydration process. At the same time, the top of the bin body 1 is also equipped with an adsorption part 9 for treating waste gas. The petroleum coke dehydration bin is reasonably designed to achieve material filtration, waste gas discharge and treatment, and effective separation of water and powder materials.

[0019] In the present invention, the filter cartridge 3 is designed to be truncated cone-shaped and larger at the bottom and smaller at the top. The scraper portion 5 includes a limit ring 51 connected to the lifting ring 4, and a scraper ring 52 is installed on the inner wall of the limit ring 51. The scraper ring 52 is made of elastic material to ensure that the scraper ring 52 can keep in contact with the surface of the filter cartridge 3 when the lifting ring 4 moves up and down, thereby effectively cleaning the surface of the filter cartridge 3. The design of the scraper ring 52 ensures the continuous cleaning of the surface of the filter cartridge 3 and improves the filtering efficiency.

[0020] In the present invention, a connection block 41 is installed at the inner wall of the lifting ring 4, and a pull wire 42 is installed at the bottom of the connection block 41. When the lifting ring 4 moves to a suitable position, the pull wire 42 will pull the filter plate 7 to salvage the powder material from the water. A pull wire 43 is installed at the bottom of the filter plate 7, and a plug 8 is installed at the bottom of the pull wire 43. A drain pipe 11 is installed at the bottom of the warehouse body 1, and the plug 8 is inserted into the drain pipe 11. When the filter plate 7 moves a certain displacement, the pull wire 43 will pull out the plug 8, thereby realizing automatic discharge of water. Through the design of the pull wire 42 and the pull wire 43, the automatic lifting of the filter plate 7 and the automatic discharge of water are realized, thereby improving the dehydration efficiency.

[0021] In the present invention, a discharge pipe 12 is installed at the bottom of the bin body 1, and the discharge pipe 12 extends all the way to the bottom of the rotating plate 2. A feed groove 121 is provided on the top surface of the discharge pipe 12 so as to discharge the powder material when the filter plate 7 moves to this position. A slide hole 71 is provided on the top of the filter plate 7, and the discharge pipe 12 contacts the inner wall of the slide hole 71 to ensure that the powder material can smoothly enter the discharge pipe 12. The design of the discharge pipe 12 and the feed groove 121 ensures the effective discharge of the powder material and avoids material waste and blockage.

[0022] In the present invention, an air duct 14 is installed on the top of the silo 1, and the air duct 14 is connected to the adsorption part 9. A feed pipe 15 and a discharge pipe 16 are installed on the surface of the silo 1, and the feed pipe 15 is arranged at the bottom of the partition 13, and the discharge pipe 16 is arranged at the top of the rotating plate 2. Such a design allows the material to enter the silo 1 smoothly, and the waste gas can enter the adsorption part 9 through the air duct 14 for treatment. The reasonable layout of the air duct 14, the feed pipe 15 and the discharge pipe 16 ensures the smooth entry and exit of the material and the effective treatment of the waste gas.

[0023] In the present invention, the adsorption part 9 is mainly composed of a barrel body 91 connected to the top of the air guide pipe 14, a barrel cover 92 is installed on the top of the barrel body 91, and an exhaust pipe 94 is installed on the top of the barrel cover 92. An activated carbon adsorption layer 93 is installed on the inner wall of the barrel body 91 for adsorbing the gas introduced into the barrel body 91. The design of the activated carbon adsorption layer 93 ensures the effective treatment of the exhaust gas and improves the air quality.

[0024] In the present invention, the surface of the barrel body 91 and the inner wall of the barrel cover 92 are connected by threads, which is convenient for disassembly and cleaning. A support ring 95 is installed on the inner wall of the barrel body 91 to support the activated carbon adsorption layer 93 to ensure its stability during operation. The design of the threaded connection and the support ring 95 improves the stability and maintainability of the adsorption part 9.

[0025] In the present invention, the driving part 6 is mainly composed of a mounting frame 61 mounted on the top of the bin body 1, a motor 62 is mounted at the bottom of the mounting frame 61, and a rotating rod 63 is mounted at the output end of the motor 62. The bottom of the rotating rod 63 penetrates into the bin body 1 and is connected to the top of the rotating plate 2, thereby realizing the rotation of the rotating plate 2. The design of the driving part 6 realizes the automatic rotation of the rotating plate 2, thereby improving the working efficiency of the dehydration bin.

[0026] The working principle of the present invention is as follows: the petroleum coke material to be dehydrated is fed into the silo 1 through the feed pipe 15 on the surface of the silo 1. At this time, the partition 13 is located above the feed pipe 15, which effectively separates the petroleum coke to be dehydrated from the discharged gas, and prevents the gas from re-entering the outside of the filter cartridge 3 and affecting the filtering effect. The design of the filter cartridge 3 helps to intercept larger particles and impurities, while allowing liquids and some fine particles to pass through. During the filtering process, the generated waste gas is discharged through the exhaust port 31 at the top of the filter cartridge 3 and enters the adsorption part 9 along the air guide pipe 14. The activated carbon adsorption layer 93 in the adsorption part 9 adsorbs the waste gas, and the purified gas is discharged through the exhaust pipe 94. When the lifting ring 4 moves up and down under the action of the driving mechanism, which is not described in detail but can be achieved by a motor or other means, the connecting block 41 on its inner wall pulls the filter plate 7 through the pull wire 42. During the movement of the filter plate 7, the water and the powder material are separated, and the powder material is left on the filter plate 7. At the same time, the scraper part 5 composed of the limit ring 51 and the scraper ring 52 moves up and down with the lifting ring 4 to clean the residue on the surface of the filter cylinder 3 to ensure the filtering effect. When the filter plate 7 moves to the feed slot 121 above the discharge pipe 12, the powder material enters the discharge pipe 12 through the slide hole 71 and the feed slot 121, and is finally discharged from the bottom of the warehouse body 1. Subsequently, the pull wire 2 43 pulls out the plug 8 while continuing to move, allowing the water at the bottom of the warehouse body 1 to be discharged through the drain pipe 11, and the motor 62 drives the rotating plate 2 to rotate in the warehouse body 1 through the rotating rod 63. The rotation of the rotating plate helps to evenly distribute and mix the materials in the warehouse body and improve the dehydration efficiency. After a period of dehydration treatment, the remaining powder material is discharged from the surface of the warehouse body 1 through the discharge pipe 2 16, completing the entire dehydration process. The activated carbon adsorption layer 93 of the adsorption part 9 is regularly replaced or cleaned to ensure its adsorption effect, clean the residues of the filter cylinder 3 and the scraper part 5, and keep the equipment clean and efficient.
