Technical Field

[0001] The utility model relates to the technical field of electric desalination tank flushing, in particular to an electric desalination tank. Background Art

[0002] The electric desalination tank is an electric desalination device equipped with a feed distributor, an oil collector, a high-voltage electric field, a water flushing facility, a drainage system, an oil-water interface detector and other components. Its working principle is to use the electric field generated between the positive and negative electrodes to make the anions and cations in the water move to the positive and negative electrodes respectively, thereby achieving the purpose of desalination. In addition, the electric desalination technology has the advantages of high desalination efficiency, large processing capacity, low energy consumption, and environmental friendliness. It is widely used in water treatment, cooling circulating water treatment, seawater desalination, etc. in industrial and civil fields. At the same time, it also has important applications in oilfield wastewater treatment and chemical reclaimed water reuse.

[0003] When using an electric desalter to dehydrate and desalt crude oil, a large amount of sludge impurities will adhere to the bottom of the electric desalter and be discharged from the cut pipe after being flushed through the flushing pipe. However, the nozzle direction of the flushing pipe is fixed, and the flushing range of the sludge on the inner wall of the electric desalter is small. After flushing, a large amount of sludge still exists in other parts, which affects the use of the electric desalter.

[0004] Therefore, an electric desalination tank is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-3 The present embodiment provides an electric desalination tank, including a tank body 1, a sealed bearing 5 is installed at one end of the tank body 1, a flushing pipe 6 is installed on the inner side of the sealed bearing 5, a plurality of flushing ports 601 are opened at equal intervals on the outer ring surface of the flushing pipe 6, the flushing ports 601 are located inside the tank body 1, a connecting plate 7 is fixedly mounted on the outer ring surface of the other end of the flushing pipe 6, a motor 9 is installed at the other end of the tank body 1, an eccentric wheel 10 is installed at one end of the rotating shaft of the motor 9, a paddle plate 11 is fixedly mounted on one side of the outer ring surface of the eccentric wheel 10, and the paddle plate 11 is located above one end of the top of the connecting plate 7. When flushing the inner bottom of the tank body 1, the motor 9 rotates to drive the eccentric wheel 10 to rotate, and the eccentric wheel 10 drives the paddle plate 11 to rotate when rotating. When the paddle plate 11 rotates, it presses one end of the connecting plate 7 down for a distance and then releases it. During this process, the connecting plate 7 drives the flushing pipe 6 to rotate, so that the flushing port 601 can flush different positions of the bottom of the tank body 1. During the continuous rotation of the motor 9, the flushing pipe 6 forms a scanning flushing in a fixed range, so that the inner bottom of the tank body 1 can be flushed more cleanly, avoiding the attached sludge impurities from piling up thicker and affecting the normal use of the electric desalination tank.

[0025] In this embodiment, if Figure 2 As shown, a cut-out pipe 8 is installed at the inner bottom of the tank body 1, one end of the cut-out pipe 8 is located at the inner bottom of the tank body 1 and is connected to the sewage discharge pipe 4. The cut-out pipe 8 is higher than the installation position of the flushing pipe 6, so that the sludge flushed by the flushing pipe 6 floats up and enters the cut-out pipe 8. The sludge moves horizontally in the cut-out pipe 8 and is finally discharged through the sewage discharge pipe 4.

[0026] In this embodiment, if Figure 1 and Figure 2As shown, sealed bearings 5 ​​are installed at the bottom positions of both ends of the tank body 1, and both ends of the flushing pipe 6 are rotatably connected to the inner sides of the two sealed bearings 5 ​​respectively. One end of the flushing pipe 6 is located outside the tank body 1 and connected to the water supply pipe. At this time, after the flushing pipe 6 is connected to the water supply pipe, it can still be rotated within a certain arc through the two sealed bearings 5.

[0027] In this embodiment, if Figure 2 As shown, the weight of the flushing pipe 6 is designed so that the center of gravity is vertically downward and the flushing port 601 is arranged on the side of the flushing pipe 6, so that the flushing pipe 6 can return to its initial position under the action of the gravity of the center of gravity each time the flushing pipe 6 rotates.

[0028] Working principle: When flushing the sludge at the bottom of the electric desalination tank, the flushing pipe 6 is first connected to the water supply pipe. At this time, the water inside the flushing pipe 6 forms a certain water pressure and is ejected through the flushing port 601 to flush the inner bottom of the tank body 1. In this process, the motor 9 rotates to drive the eccentric wheel 10 to rotate, and the eccentric wheel 10 drives the paddle plate 11 to rotate when rotating. When the paddle plate 11 rotates, it presses one end of the connecting plate 7 down for a distance and then releases it. In this process, the connecting plate 7 drives the flushing pipe 6 to rotate, so that the flushing port 601 can flush different positions at the bottom of the tank body 1. After each rotation of the flushing pipe 6, the flushing pipe 6 can return to its initial position under the action of the center of gravity. At the same time, during the continuous rotation of the motor 9, the flushing pipe 6 forms a scanning flushing of a fixed range, so that the inner bottom of the tank body 1 can be flushed more cleanly, avoiding the attached sludge impurities from piling up thicker and affecting the normal use of the electric desalination tank.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
