[0001] The utility model relates to the technical field of environmental protection treatment equipment, in particular to petroleum refining environmental protection treatment equipment. Background Art

[0002] Petroleum fuel is a liquid fuel that is easy to use and has high energy utilization efficiency. The fuel for high-speed, high-power transportation vehicles such as airplanes and automobiles is mainly provided by the petroleum refining industry. A large amount of industrial wastewater is generated in the process of petroleum refining. The industrial wastewater contains elements that are harmful to the environment and needs to be treated for environmental protection before it can be discharged.

[0003] In order to improve the efficiency of environmental protection treatment of wastewater generated by petroleum refining, the prior art has made many improvements to environmental protection treatment equipment. For example, the patent with patent publication number CN211813620U discloses an environmental protection treatment equipment for petroleum refining, including a support rod and a mounting frame, the mounting frame is fixedly connected to the top of the support rod, the lower end of the support rod is fixedly connected to a collecting bucket, the mounting frame is fixedly connected to a treatment tank, the top surface of the treatment tank is fixedly connected to an injection pipe, the side wall of the treatment tank is fixedly installed with a drain faucet, the bottom end of the treatment tank is fixedly connected to a conical tank, the bottom end of the conical tank is fixedly installed with an electric discharge valve, the upper end of the treatment tank is installed with a driving mechanism, the driving mechanism is matched with a stirring and mixing mechanism, and the stirring and mixing mechanism is installed inside the treatment tank; the utility model effectively solves the problems of insufficient stirring in the existing design, poor wastewater treatment effect and low working efficiency.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] See also Figure 1-Figure 9 The petroleum refining environmental protection treatment equipment of this embodiment includes a treatment tank 1, a liquid inlet 2 and a dosing port 3 are arranged on the side of the treatment tank 1, a discharge port 4 is arranged at the lower end of the treatment tank 1, a movable pressing plate 5 capable of moving up and down inside the treatment tank 1 is arranged in the treatment tank 1, a driving motor 6 is arranged at the upper end of the treatment tank 1, a connecting column 7 penetrating the movable pressing plate 5 is fixedly connected to the output end of the driving motor 6, a spring 8 sleeved on the side of the connecting column 7 is arranged between the upper surface of the movable pressing plate 5 and the inner top wall of the treatment tank 1, a screw rod 9 is fixedly installed at the lower end of the connecting column 7, and a plurality of elastic stirring belts 10 are arranged on the side of the screw rod 9; wherein, when the output end of the driving motor 6 rotates forward, the stirring belt 10 stirs the wastewater inside the treatment tank 1, and when the output end of the driving motor 6 rotates reversely, the movable pressing plate 5 is subjected to the extrusion force of the spring 8 and meshes with the thread teeth of the screw rod 9, and the screw rod 9 drives the movable pressing plate 5 to move downward to suppress the sediment, and the wastewater located above the movable pressing plate 5 is discharged through the drainage unit.

[0034] When it is necessary to flocculate the wastewater, the wastewater generated by the petroleum refining is pumped into the treatment tank 1 through the liquid inlet 2, and the wastewater treatment agent such as the flocculant is added into the treatment tank 1 through the dosing port 3, and the drive motor 6 is started to rotate forward. When the drive motor 6 rotates forward, its output end drives the connecting column 7 to rotate, and the connecting column 7 drives the screw rod 9 to rotate, and the screw rod 9 drives the elastic stirring belt 10 to rotate. The threaded teeth on the screw rod 9 cannot mesh with the threaded teeth on the movable pressing plate 5, so the movable pressing plate 5 is above the screw rod 9. When the wastewater treatment agent and the wastewater are fully mixed, the output end of the drive motor 6 is controlled to reverse, and the drive motor 6 reverses. When the screw rod 9 is reversed, the connecting column 7 and the screw rod 9 are driven to reverse. When the screw rod 9 is reversed, the moving pressure plate 5 is pushed downward by the spring 8, and the threads on the moving pressure plate 5 are meshed with the threads on the screw rod 9. The screw rod 9 rotates slowly to drive the moving pressure plate 5 to move downward. When the moving pressure plate 5 moves downward, the elastic stirring belt 10 contracts, and the sediment at the bottom of the treatment tank 1 is suppressed by the moving pressure plate 5, and the wastewater above the moving pressure plate 5 is pumped out through the drainage unit. Since the sediment is blocked by the moving pressure plate 5, when the treated wastewater is discharged, it will not cause the secondary floating of the sediment below, thereby improving the wastewater treatment effect.

[0035] It is worth mentioning that, by moving the pressing plate 5 downward, the sediment under the treatment tank 1 is squeezed, the water content in the sediment is reduced, and the sediment is discharged through the discharge port 4, thereby improving the treatment effect of the wastewater. At the same time, when the pressing plate 5 is moved downward, the inner wall of the treatment tank 1 can be cleaned, and the impurities adhered to the side wall of the treatment tank 1 can be pushed to the bottom of the treatment tank 1, thereby improving the cleanliness of the inside of the treatment tank 1.

[0036] Among them, the above-mentioned drive motor 6 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The drive motor 6 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0037] As a technical optimization solution of the utility model, the drainage unit includes a water pump 11 fixedly installed on the upper end of the treatment tank 1, a hose 12 fixedly installed on the water pump 11, an end of the hose 12 away from the water pump 11 is located in the treatment tank 1 and fixedly installed with a filter head 13, and a mounting frame 14 for fixedly installing the filter head 13 is provided on the upper surface of the movable pressure plate 5.

[0038] The hose 12 can be retracted and deformed, and the filter head 13 has the effect of secondary filtration, while preventing blockage inside the hose 12. The filter head 13 moves with the downward movement of the movable pressure plate 5. No matter how much sediment is in the treatment tank 1, the filter head 13 can extract the wastewater above the movable pressure plate 5, thereby improving the wastewater extraction efficiency.

[0039] Among them, the water pump 11 mentioned above can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The water pump 11 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0040] As a technical optimization solution of the utility model, the lower cavity in the processing tank 1 is a truncated cone that is wide at the top and narrow at the bottom. A plurality of cleaning rods 15 that are adapted to the lower cavity of the processing tank 1 are fixedly installed at the lower end of the screw rod 9. One side of the cleaning rod 15 is attached to the inner wall of the processing tank 1, and reinforcing rods 23 are fixedly connected between adjacent cleaning rods 15.

[0041] When the sediment needs to be discharged, the rotating cleaning rod 15 cooperates with the lower cavity in the processing tank 1 to push the sediment on the inner edge of the processing tank 1 into the discharge port 4 for discharge. At the same time, the lower side wall of the processing tank 1 can be cleaned by the cleaning rod 15. The reinforcing rod 23 increases the connection strength of several cleaning rods 15, which is convenient for discharging the sediment and can clean the bottom of the processing tank 1 at the same time.

[0042] As a technical optimization solution of the utility model, a symmetrical limit block 16 is fixedly connected to the side of the movable platen 5, and a symmetrical limit groove 17 adapted to the limit block 16 is opened on the inner wall of the processing tank 1. When the screw 9 rotates, the movable platen 5 is restricted by the limit groove 17 on the limit block 16, and the movable platen 5 can only move up and down in the processing tank 1, and will not rotate with the rotation of the screw 9.

[0043] As a technical optimization scheme of the utility model, an upper movable ring 18 sleeved on the side of the screw rod 9 is fixedly installed on the lower surface of the movable pressure plate 5, one end of a plurality of stirring belts 10 is fixedly installed on the side of the upper movable ring 18, a lower movable ring 19 is sleeved on the side of the lower end of the screw rod 9, and the lower ends of the plurality of stirring belts 10 are fixedly installed on the side of the lower movable ring 19. The upper movable ring 18 and the lower movable ring 19 can only move up and down on the side of the screw rod 9. The inner side walls of the upper movable ring 18 and the lower movable ring 19 are fixedly connected with sliding blocks 20, and a sliding groove 21 adapted to the sliding block 20 is opened on the side of the screw rod 9.

[0044] The upper movable ring 18 is fixedly installed on the lower surface of the movable pressure plate 5 by fasteners. When the movable pressure plate 5 rises and falls, it will drive the upper movable ring 18 to move up and down. The stirring belt 10 is made of elastic material and can be deformed. When it is necessary to stir the inside of the treatment tank 1, the screw rod 9 rotates at high speed. Due to the action of centrifugal force, the stirring belt 10 stirs the wastewater inside the treatment tank 1 in an arc shape. When drainage is required, the movable pressure plate 5 moves downward, and the sliding block 20 slides in the sliding groove 21, thereby improving the applicability of the device.

[0045] As a technical optimization solution of the utility model, bearings 22 are fixedly connected to both ends of the spring 8. The two bearings 22 are respectively against the upper side of the movable pressure plate 5 and the inner top wall of the processing tank 1. The bearings 22 are thrust roller bearings or thrust ball bearings. The bearings 22 prevent the spring 8 from deforming during use.

[0046] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
