Description

Technical Field

[0001] The utility model relates to the technical field of ship waste oil treatment, in particular to a device for removing ash from ship waste oil. Background Technique

[0002] Ship oil pollution treatment technology is still constantly innovating and developing. Internationally, two methods of physical and chemical technology and biological technology are generally adopted. Physical and chemical technologies such as adsorption, centrifugation and sedimentation can effectively remove oil pollution; biological technologies such as biosorption and biodegradation have also been applied.

[0003] During use, the treatment of ship oil pollution in China mainly adopts "pretreatment + atmospheric and vacuum distillation + solvent refining" for recycling. It mainly separates finished fuel oil and oil-containing ash by vacuum distillation in a cracking unit. The recovered finished fuel oil can be applied to industries such as oil refining and chemical industry, transportation, construction and metallurgy. However, due to the different properties of ship sewage oil and waste lubricating oil, and the main component is ship fuel oil, this process plan is not fully applicable. Therefore, a corresponding No. 2 chelating deashing agent is added to the upper oil product after separation to react with the impurities doped in the separated oil product to form a flocculent precipitate. However, since the reaction produces a flocculent precipitate, it is often necessary to let it stand still to complete the precipitation of the floccules inside, and then extract the stratified liquid to achieve solid-liquid separation. During this process, the time required for static precipitation is too long, and when extracting and separating the liquid, it is extremely easy to cause some of the stratified liquid to not be fully extracted due to improper extraction, which affects the oil product output. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a device for removing ash from ship waste oil to solve the technical problems that the time required for current static precipitation is too long and when extracting and separating the liquid, it is extremely easy to cause some of the stratified liquid to not be fully extracted due to improper extraction, which affects the oil product output.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a device for removing ash from ship waste oil, including a hollow frame and a transmission frame. The top of the hollow frame is detachably installed with a sealing cover through bolts. A reaction barrel is fixedly installed inside the hollow frame. The outer surface of the reaction barrel is movably and tightly sleeved with a shielding frame, and the shielding frame is rotatably installed inside the hollow frame;

[0006] Both ends of the inner bottom of the sealing cover are fixedly installed with fixing plates, and the number of fixing plates is four groups. A transmission rod is rotatably installed through bearings between the middle ends of every two groups of the fixing plates. Fixed blocks are fixedly sleeved on the surfaces of both ends of the outer side of each transmission rod. A connecting plate is vertically fixedly installed on the bottom surface of each fixed block, and the outer side of the connecting plate is fixedly connected to the outer surface of the shielding frame;

[0007] A hollow frame is horizontally fixedly installed on the side of the bottom of the sealing cover. A bidirectional lead screw is horizontally rotatably installed inside the hollow frame through bearings. Transmission sleeves are movably sleeved on the surfaces of both ends of the outer side of the bidirectional lead screw through threads. A transmission frame is fixedly installed on the bottom surface of the outer side of each transmission sleeve, and the transmission frame is slidably installed through the bottom end inside the hollow frame;

[0008] A transmission rack is fixedly installed on the side surface of each transmission frame. A follower gear is fixedly sleeved on the side surface of each transmission rod close to the hollow frame, and the bottom of the follower gear meshes with the top of the transmission rack.

[0009] Preferably, a screening mesh frame is fixedly embedded inside the reaction barrel. A scraping block is slidably installed on the inner bottom of the reaction barrel. A rotating rod is vertically rotatably installed through a bearing at the middle end of the top of the scraping block, and the top of the rotating rod is installed through a bearing inside the middle end of the sealing cover.

[0010] Preferably, a rotating motor is fixedly installed on the surface of the top end of the sealing cover, and the bottom of the transmission shaft of the rotating motor is fixedly connected to the top of the rotating rod through a coupling. Stirring rods are fixedly installed on the outer surface of the rotating rod, and the number of the stirring rods is several groups.

[0011] Preferably, a servo motor is fixedly installed on the outer surface of the transmission frame, and the side of the transmission shaft of the servo motor is fixedly connected to the outer side of the bidirectional lead screw through a coupling.

[0012] Preferably, a feed pipe is vertically fixedly communicated on the side of the top of the sealing cover. A discharge groove is opened at the bottom of the hollow frame.

[0013] Preferably, a sealing rubber strip is fixedly adhered to the side surface of each shielding frame.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The utility model has shielding frames rotatably arranged at both ends of the outer side of the reaction barrel, and a screening mesh frame is fixedly embedded and installed inside the reaction barrel, so that after the oil body to be chelated, deashed and flocculated and the flocculant are put into the reaction barrel, the shielding frame blocks and blocks the screening mesh frame inside the reaction barrel from both sides, ensuring that the oil body and the flocculant can fully react and will not flow out from the inside at will. After the full reaction and flocculation are completed, it does not need to be left still for a long time, but only needs to drive the transmission sleeve and the transmission rack to move horizontally through the rotation of the bidirectional screw rod, and then the driven gear and the transmission rack are combined to move horizontally. Under the action of meshing transmission, the two sets of rotating rods can drive the shielding frame to synchronously rotate relative to the outer wall of the reaction barrel and automatically open, so that when the shielding frame cannot shield and close the reaction barrel and the screening frame, the flocculated oil body and flocculated sediment inside can automatically flow out and separate under the screening action of the screening frame, so that the oil body after impurity removal can be removed from the discharge chute, and the flocculent sediment can be automatically stored in the reaction barrel, thereby improving the separation rate of the flocculated mixture and ensuring that the liquid after impurity removal can be fully discharged without affecting the oil body reaction yield due to incomplete separation.

[0016] 2. The utility model drives the sealing cover and the scraper block with a trapezoidal cross section located inside the reaction barrel to be connected by a rotating rod, so that after the sealing cover is opened from the top of the hollow frame and moved vertically, the scraper block can be driven to move vertically inside the reaction barrel synchronously, so that the outer edge of the scraper block can gather and move the flocculent sediment accumulated inside the reaction barrel, which is convenient for the operator to clean the flocculent sediment accumulated inside the reaction barrel from the top, thereby improving the cleaning efficiency of the flocculent sediment and the reuse rate of the overall mechanism.

[0025] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0026] Embodiment 1: A device for removing ash from ship waste oil, see Figures 1 to 4 , including a hollow frame 1 and a transmission frame 25. The top of the hollow frame 1 is detachably installed with a sealing cover 11 through bolts. The inner side of the hollow frame 1 is fixedly installed with a reaction barrel 12. The outer surface of the reaction barrel 12 is movably and fittingly sleeved with a shielding frame 14, and the shielding frame 14 is rotatably installed inside the hollow frame 1. Both ends of the inner bottom of the sealing cover 11 are fixedly installed with fixed plates 2, and the number of fixed plates 2 is four groups. Between the middle ends of every two groups of fixed plates 2, a transmission rod 21 is rotatably installed through a bearing. The outer surfaces of both ends of each transmission rod 21 are fixedly sleeved with fixed blocks 22. The bottom surfaces of each fixed block 22 are vertically fixedly installed with connecting plates 23, and the outer sides of the connecting plates 23 are fixedly connected to the outer surface of the shielding frame 14. The bottom side of the sealing cover 11 is horizontally fixedly installed with a hollow frame 1. A bi-directional lead screw 26 is horizontally rotatably installed inside the hollow frame 1. The outer surfaces of both ends of the bi-directional lead screw 26 are movably sleeved with transmission sleeves 27 through threads. The bottom surfaces of the outer sides of each transmission sleeve 27 are fixedly installed with transmission brackets 28, and the transmission brackets 28 are slidably installed through the bottom end inside the hollow frame 1. The side surfaces of each transmission bracket 28 are fixedly installed with transmission racks 29. The side surfaces of each transmission rod 21 close to the hollow frame 1 are fixedly sleeved with follow-up gears 24, and the bottoms of the follow-up gears 24 are meshed with the tops of the transmission racks 29. Through the rotational transmission of the bi-directional lead screw 26 to the transmission sleeve 27, and the meshing transmission of the transmission rack 29 and the follow-up gear 24, the two rotating rods 16 can drive the shielding frame 14 to rotate relatively synchronously from the outer wall of the reaction barrel 12 and automatically open. While ensuring that the normal flocculent precipitation reaction of the oil body is fully carried out, the flocculated oil body and the flocculated precipitate can automatically flow out and separate under the screening action of the screening mesh frame 13, so that the oil body after impurity removal can be removed from the discharge groove 19, and the flocculent precipitate can be automatically stored inside the reaction barrel 12, improving the separation rate of the flocculated mixture and ensuring that the liquid after impurity removal can be fully discharged without affecting the reaction yield of the oil body due to incomplete separation.

[0027] Specifically, seeFigures 1 to 4 A screening mesh frame 13 is fixedly embedded in the reaction barrel 12, and a scraper block 3 is slidably installed on the bottom of the inner side of the reaction barrel 12. A rotating rod 16 is installed on the middle end of the top of the scraper block 3 for vertical rotation through a bearing, and the top of the rotating rod 16 is installed inside the middle end of the sealing cover 11 through a bearing. The scraper block 3 and the sealing cover 11 are connected by transmission through the rotating rod 16, so that when the sealing cover 11 is pulled and lifted, the scraper block 3 is driven to move vertically to aggregate and move the flocculent sediment inside the reaction barrel 12.

[0028] For further information, see Figures 1 to 4 A rotating motor 15 is fixedly mounted on the top terminal surface of the sealing cover 11, and the bottom of the driving shaft of the rotating motor 15 is fixedly connected to the top of a rotating rod 16 through a coupling. A stirring rod 17 is fixedly mounted on the outer surface of the rotating rod 16, and the number of the stirring rods 17 is several groups. The mixing degree of the deliming agent and the oil body is improved through the structural effect of the stirring rod 17, thereby accelerating the reaction rate.

[0029] It is worth noting that see Figures 1 to 4 A servo motor 41 is fixedly mounted on the outer surface of the transmission frame 25, and the side of the transmission shaft of the servo motor 41 is fixedly connected to the outer side of the bidirectional screw rod 26 through a coupling. The servo motor 41 can provide the power required for the rotation of the bidirectional screw rod 26 through the structural function.

[0030] It is worth noting that see Figures 1 to 4 The top side of the sealing cover 11 is vertically fixed with a feed pipe 18, and the bottom of the hollow frame 1 is provided with a discharge trough 19. The feed pipe 18 and the discharge trough 19 enable the material to be fed and discharged.

[0031] It is worth mentioning that see Figures 1 to 4 A sealing strip 4 is fixedly bonded to the side surface of each shielding frame 14. The sealing strip 4 can seal the mutually fitting positions of the two sets of shielding frames 14 through the structural effect, further improving the shielding and sealing quality of the shielding frame 14 on the reaction barrel 12.

[0032] During operation, the oil body to be chelated and deashed and the No. 2 chelating deashing agent required for precipitation are transported into the interior of the reaction barrel 12 through the feed pipe 18. After that, under the shielding and sealing effect of the shielding frame 14 and the sealing strip 4 on the interior of the reaction barrel 12, the rotation motor 15 is synchronously started, and its operation drives the rotating rod 16 and the stirring rod 17 to rotate synchronously inside the reaction barrel 12, and then the oil body and the deashing agent are fully stirred and mixed, so that the impurities inside the oil body can be flocculated. After sufficient reaction and flocculation, the servo motor 41 is turned on through an external control switch, and its operation drives the bidirectional lead screw 26 to rotate inside the transmission frame 25. After that, under the rotational transmission effect of the bidirectional lead screw 26 on the transmission sleeve 27, the two groups of transmission sleeves 27 can be driven to move horizontally in opposite directions synchronously. Then, under the transmission effect of the transmission frame 28, the transmission rack 29 is driven to move horizontally in opposite directions synchronously inside the hollow frame 1. Furthermore, under the meshing transmission effect of the transmission rack 29 and the follower gear 24, the two groups of follower gears 24 and the transmission rod 21 can be driven to rotate in opposite directions synchronously, so that the shielding frame 14 originally attached to the outer wall of the reaction barrel 12 can rotate relative to it and detach and open from its surface, so that the shielding frame 14 does not shield and seal the outside of the reaction barrel 12. Under the screening effect of the screening mesh frame 13, the reacted oil body can flow and be discharged through the screening mesh frame 13 and the discharge groove 19, while the flocculent precipitate remains inside the screening mesh frame 13 and the reaction barrel 12. Then, the sealing cover 11 is opened and moved vertically. Under the transmission effect of the rotating rod 16, the scraping block 3 is driven to lift vertically inside the screening mesh frame 13 and the reaction barrel 12, so that the scraping block 3 can perform the operation of aggregating and removing the flocculent precipitate remaining inside it. After moving the flocculent precipitate to the upper end inside the reaction barrel 12, the operator can then perform centralized cleaning on it, and thus the chelating and deashing treatment of the oil body can be completed.

[0033] In addition, the components designed in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. Those skilled in the art can fully implement them without further elaboration.

[0034] The embodiments disclosed in the present utility model are the preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are all within the protection scope of the present utility model.
