Description

Technical Field

[0001] This utility model relates to the field of cooling technology, specifically to a petroleum coke particle screening and cooling device. Background Technology

[0002] Petroleum coke, an important byproduct of crude oil distillation and thermal cracking, has its cooling process directly impacting product quality and production efficiency. Visually, petroleum coke appears as irregularly shaped, black lumps or granules of varying sizes. These granules have a porous structure and are primarily composed of carbon, but also contain hydrogen, oxygen, nitrogen, sulfur, and metallic elements. Efficient cooling of particles of different sizes is a crucial step in petroleum coke production, but current technologies have significant shortcomings in this area.

[0003] Currently, traditional petroleum coke cooling equipment generally suffers from the inability to accurately screen and cool particles of different sizes. Existing technologies mostly employ a uniform cooling method without screening the petroleum coke particles by size, resulting in uneven heating of particles of different volumes during the cooling process. For small petroleum coke particles, due to their large specific surface area, using the same cooling time and water volume as for larger particles will cause them to absorb water and clump together due to excessive contact with cooling water. This not only seriously affects subsequent processing but also reduces the quality of the petroleum coke product.

[0004] Meanwhile, existing equipment often requires spraying large amounts of cooling water to ensure cooling effectiveness. This not only wastes water resources but also makes it easy for small particles of petroleum coke to mix with the cooling water during discharge. This leads to a waste of petroleum coke resources and increases the difficulty of subsequent wastewater treatment, thereby raising production costs.

[0005] Therefore, it is necessary to provide a petroleum coke particle screening and cooling device to solve the above problems. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the purpose of this utility model is to provide a petroleum coke particle screening and cooling device to solve the problems mentioned in the background technology.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a petroleum coke particle screening and cooling device, including a screening machine and a conveyor. The screening machine is located above one end of the conveyor. The screening machine has a small particle hopper and a large particle hopper for receiving petroleum coke particles. The top of the small particle hopper and the large particle hopper are respectively connected to a small particle nozzle and a large particle nozzle. A liquid collection tank is installed inside the conveyor. The liquid collection tank is connected to the small particle nozzle and the large particle nozzle through a pipeline unit.

[0008] Furthermore, the small particle hopper is located near one end of the conveyor, and the large particle hopper is located on one side of the small particle hopper with its top end lower than that of the small particle hopper. The inner cavity of the small particle hopper has two downwardly inclined small particle baffles arranged alternately, and the inner cavity of the large particle hopper has four downwardly inclined large particle baffles arranged alternately.

[0009] Furthermore, the screening machine has a hopper, a screen box, and a support. The hopper is hinged to one side of the screen box and aligned with the top of the screen box. The screen box is hinged to one side of the support and located above the support. A vibrating motor is fixedly connected to one side of the screen box.

[0010] Furthermore, both the small particle hopper and the large particle hopper are mounted on a support, and the screen box is tilted above the small particle hopper;

[0011] An arc-shaped guide plate is also connected to one side of the screen box, and the end of the guide plate away from the screen box extends into the large particle hopper.

[0012] Furthermore, the conveyor has two baffles and a conveyor belt. Rollers are connected to both ends of the conveyor belt to drive its rotation. The rollers are connected to a drive to make it run. The baffles are all arranged along the length of the conveyor. The conveyor belt is located between the two baffles. The top of the baffle is higher than the bottom of the small particle hopper and the large particle hopper.

[0013] Furthermore, the liquid collection tank has an upward-opening receiving cavity, the length and width of which correspond to the transmission mesh belt.

[0014] Furthermore, the pipeline unit consists of a hose and a water pump. The liquid collection tank is connected to a discharge port on the side near the screening machine. The discharge port is connected to the water inlet of the small particle nozzle and the large particle nozzle through a pipe. The water pump is connected to the hose to provide power.

[0015] Furthermore, the bottom of the receiving cavity is a sloped surface, and the height of the sloped surface gradually decreases from the end away from the screening machine to the end of the discharge port.

[0016] The beneficial effects of this utility model are: the petroleum coke particle screening and cooling device provided by this utility model can screen petroleum coke particles of different sizes by setting a screening machine, and then cool them by small particle bucket and large particle bucket, which can accurately screen and cool petroleum coke particles.

[0017] Secondly, by setting an appropriate number of baffles in the small and large particle hoppers, the residence time of petroleum coke particles in the small and large particle hoppers is changed. The residence time of petroleum coke particles in the small particle hopper is controlled to be short to prevent prolonged cooling, water absorption, and clumping. The residence time of petroleum coke particles in the large particle hopper is controlled to be long to prevent insufficient cooling during the cooling process.

[0018] Meanwhile, by incorporating piping units to circulate the coolant and using baffles to prevent coolant splashing, waste is reduced, and the overall efficiency and economy of the cooling system are improved.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0025] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0027] like Figure 1-2As shown, the present invention provides a technical solution: a petroleum coke particle screening and cooling device, including a screening machine 1 and a conveyor 4. The screening machine 1 is located above one end of the conveyor 4. The screening machine 1 has a small particle hopper 2 and a large particle hopper 3 for receiving petroleum coke particles. The top of the small particle hopper 2 and the large particle hopper 3 are respectively connected to a small particle nozzle 21 and a large particle nozzle 31. A liquid collection tank 5 is installed inside the conveyor 4. The liquid collection tank 5 is connected to the small particle nozzle 21 and the large particle nozzle 31 through a pipeline unit.

[0028] The small particle hopper 2 is located near one end of the conveyor 4, and the large particle hopper 3 is located to one side of the small particle hopper 2, with its top end lower than that of the small particle hopper 2. Two downward-sloping small particle baffles 22 are alternately arranged inside the small particle hopper 2, and four downward-sloping large particle baffles 32 are alternately arranged inside the large particle hopper 3. Petroleum coke particles of both sizes enter the small particle hopper 2 and the large particle hopper 3 respectively. The petroleum coke particles in the small particle hopper 2 slide downwards along the small particle baffles 22, and the petroleum coke particles in the large particle hopper 3 slide downwards along the large particle baffles 32, until they fall onto the conveyor 4.

[0029] The screening machine 1 has a hopper 11, a screen box 13 and a support 14. The hopper 11 is hinged to one side of the screen box 13 and aligned with the top of the screen box 13. The screen box 13 is hinged to one side of the support 14 and located above the support 14. A vibrating motor 12 is fixedly connected to one side of the screen box 13.

[0030] Both the small particle hopper 2 and the large particle hopper 3 are installed on the bracket 14, and the screen box 13 is inclined and set above the small particle hopper 2.

[0031] An arc-shaped guide plate 15 is also connected to one side of the screen box 13, with the end of the guide plate 15 away from the screen box 13 extending into the large particle hopper 3. The small particle hopper 2 receives small petroleum coke particles that pass through the screen box 13, while the large particle hopper 3 receives large petroleum coke particles that do not pass through the screen box 13 and come down from the roller.

[0032] The conveyor 4 has two baffles 41 and a conveyor belt 42. Rollers are connected to both ends of the conveyor belt 42, driving its rotation. The rollers are connected to a drive mechanism to operate the conveyor. The baffles 41 are arranged along the length of the conveyor 4, and the conveyor belt 42 is located between the two baffles 41. The top of the baffles 41 is higher than the bottom of the small particle hopper 2 and the large particle hopper 3. The drive mechanism can be a motor or a chain drive to rotate the conveyor belt 42. The gap in the conveyor belt 42 is smaller than the petroleum coke particles, so that even the smallest petroleum coke particles can fall onto the conveyor belt 42.

[0033] The liquid collection tank 5 has an upward-opening receiving cavity 501, the length and width of which correspond to the transmission belt 42.

[0034] The pipeline unit consists of a hose and a water pump. The side of the collection tank 5 closest to the screening machine 1 is connected to an outlet 51. The outlet 51 is connected to the water inlet of the small particle nozzle 21 and the large particle nozzle 31 through a pipe. The water pump is connected to the hose to provide power.

[0035] The bottom of the receiving cavity 501 is a sloped section 502, and the height of the sloped section 502 gradually decreases from the end away from the screening machine 1 to the end of the discharge port 51.

[0036] In one embodiment, the graded cooling device is used as follows.

[0037] Specifically, the receiving cavity 501 is filled with coolant, and the water pump is turned on so that the coolant enters the small particle nozzle 21 and the large particle nozzle 31 from the pipe. The small particle nozzle 21 sprays the coolant into the small particle hopper 2, and the large particle nozzle 31 sprays the coolant into the large particle hopper 3. The coolant then flows out from the bottom of the small particle hopper 2 and the large particle hopper 3, passes through the conveyor belt 42, and returns to the receiving cavity 501 to form a cycle. At this time, the motor is turned on, and the conveyor belt 42 is rotated by the reducer to drive the roller.

[0038] When the vibration motor 12 is turned on, the screen box 13 begins to vibrate, and the petroleum coke particles that need to be cooled are poured into the hopper 11. The petroleum coke particles fall onto the upper surface of the screen box 13. Small-sized petroleum coke particles, after vibration, pass through the screen box 13 and fall into the small particle hopper 2 below the screen box 13. Large-sized petroleum coke particles, after vibration, do not pass through the screen box 13 and roll down along the guide plate 15 into the large particle hopper 3. Small-sized petroleum coke particles in the small particle hopper 2 are buffered and cooled by the flow of coolant through the small particle baffle 22 before falling into the large particle hopper 3. Large petroleum coke particles enter the conveyor belt 42. Inside the large particle hopper 3, they are buffered and cooled by the coolant flowing through the large particle baffle 32 before falling onto the conveyor belt 42. Since the large particle baffle 32 has more baffles than the small particle baffle 22, the large petroleum coke particles spend more time in the large particle hopper 3 than in the small particle hopper 2, resulting in more thorough cooling. Subsequently, both large and small petroleum coke particles are transported along the conveyor belt 42, and the baffle 41 effectively prevents coolant from splashing out.

[0039] In summary, this device, equipped with a screening machine 1, can screen petroleum coke particles of different sizes. The particles are then cooled using small particle hopper 2 and large particle hopper 3, enabling precise screening and cooling of the petroleum coke particles. Furthermore, by installing appropriate numbers of baffles in the small and large particle hoppers 2 and 3, the residence time of the petroleum coke particles is altered. A shorter residence time in the small particle hopper 2 prevents prolonged cooling and water absorption, thus preventing clumping. A longer residence time in the large particle hopper 3 ensures adequate cooling. Simultaneously, the installation of a piping unit circulates the coolant, and baffles 41 prevent coolant splashing, reducing unnecessary waste and improving the overall efficiency and economy of the cooling system.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
