Description

Technical Field

[0001] The utility model relates to the technical field of anthracene oil processing equipment, in particular to a flash evaporation tower. Background Art

[0002] Flash evaporation means that high-pressure saturated water enters a relatively low-pressure container, and due to the sudden drop in pressure, part of the saturated water becomes saturated water vapor and saturated water under the pressure of the container. A flash evaporation tower is a chemical engineering equipment that realizes rough gas-liquid separation of materials in the chemical production process. In the processing and production of anthracene oil, the flash evaporation tower is an essential processing equipment in the process;

[0003] For some traditional flash evaporation towers, the closing method of the surface maintenance window structure mostly adopts the method of tightening and fixing a sealing plate or a sealing frame with multiple bolts to achieve the sealing effect. As shown in the appendix, such a closing method, although stable, is extremely troublesome to operate when it is necessary to open and observe or perform maintenance work inside the flash evaporation tower later, and it lacks convenience in use. Figure 4 As shown, such a closing method, although stable, is extremely troublesome to operate when it is necessary to open and observe or perform maintenance work inside the flash evaporation tower later, and it lacks convenience in use.

[0029] Refer to Figures 1-4, an embodiment provided by the present utility model: a flash evaporation tower, including a support frame 1, a flash evaporation tower body 2 is fixedly connected to the support frame 1, an inlet 3 and an outlet 4 are respectively arranged on the flash evaporation tower body 2, and a maintenance window frame 5 is fixedly connected to one side of the outer surface of the flash evaporation tower body 2. A maintenance through groove 6 communicating with the inside of the flash evaporation tower body 2 is arranged on the maintenance window frame 5. The maintenance through groove 6 is the position of the maintenance window, which is convenient for observing the inside of the tower and carrying out maintenance work. A closed notch 7 is arranged on one side of the outer surface of the maintenance window frame 5. A sealing frame 8 is arranged outside the maintenance window frame 5. A sealing block 9 is fixedly connected to the sealing frame 8. The sealing block 9 and the closed notch 7 are arranged in a nested fit. The arrangement of the closed notch 7 and the sealing block 9 can achieve a stable sealing effect on the maintenance window position. A locking mechanism is arranged between the sealing block 9 and the closed notch 7. The setting of the locking mechanism can ensure that the sealing block 9 can be stably sealed and fixed in the closed notch 7. A handle frame 20 is fixedly connected to one side of the outer surface of the sealing frame 8. There are two handle frames 20 in total, which can facilitate the disassembly and assembly operation of the sealing frame 8 by hand;

[0030] The locking mechanism includes an inner groove 11 arranged in the sealing block 9 and a locking groove 15 arranged on the inner wall of the closed notch 7. A moving block 12 is slidably connected in the inner groove 11, and a spring 13 is connected between the inner wall of the inner groove 11 and the outer surface of the moving block 12. A locking block 14 and a traction rope 17 are respectively fixedly connected to the moving block 12. The locking block 14 is located on the side of the outer surface of the moving block 12 away from the spring 13, and the traction rope 17 is located on the same side of the outer surface of the moving block 12 as the spring 13. A pulling frame 19 is arranged outside the sealing frame 8. One end of the traction rope 17 is fixedly connected to the pulling frame 19. The locking block 14 and the locking groove 15 are arranged in a nested fit. During operation, pull the pulling frame 19 outwards. The pulling frame 19 pulls the moving block 12 to move through the traction rope 17. While the moving block 12 compresses the spring 13, it also drives the locking block 14 to contract. When the sealing block 9 is inserted into the closed notch 7, release the pulling frame 19. The spring 13 resets and pushes the moving block 12 to drive the locking block 14 to insert into the locking groove 15, and the positioning installation of the locking mechanism can be completed. The setting of the locking mechanism can not only make the structure of the sealing frame 8 stably seal the maintenance window, but also be conveniently disassembled and opened for maintenance work.

[0031] A sealing gasket 10 is fixedly connected to one side of the outer surface of the sealing block 9. The sealing gasket 10 is made of rubber material, which can ensure the tightness of the sealing of the sealing block 9.

[0032] There are two locking mechanisms located on both sides of the sealing frame 8. In each set of locking mechanisms, there are two corresponding inner grooves 11, moving blocks 12, springs 13, locking blocks 14, locking grooves 15, and traction ropes 17, which are symmetrically distributed up and down. The two traction ropes 17 are fixedly connected to the same pulling frame 19. The two sets of locking mechanisms have a total of four locking blocks 14 structures, which can ensure the stability of the entire closing block 9 after positioning and installation. The position of the pulling frame 19 is set corresponding to the position of the handle frame 20, as shown in the attached figure. Figure 1 As shown, the two pulling frames 19 and the two handle frames 20 are stacked together, which makes it convenient to disassemble and assemble the locking mechanism. During operation, the handle frames 20 are held at the base of the hand, and the pulling frames 19 are held at the finger positions. The locking mechanism can be opened by pulling the pulling frames 19 with fingers, and the entire sealing frame 8 can be removed from the inspection window frame 5 by holding the handle frames 20.

[0033] The sealing frame 8 is provided with a fixed groove 16 extending into the closing block 9. The inner groove 11 is connected to the fixed groove 16 via a connecting groove 18. The traction rope 17 passes through the connecting groove 18 and the fixed groove 16 and extends to the outer side of the sealing frame 8. The connecting groove 18 and the fixed groove 16 are perpendicular to each other. The two can guide the traction rope 17 so that the locking mechanism can be operated normally.

[0034] Working principle: When using the flash tower, grasp the handle frame 20, and pull the pulling frame 19 with your fingers. The pulling frame 19 pulls the moving block 12 to move through the traction rope 17. The moving block 12 compresses the spring 13 and also drives the locking block 14 to contract, inserting the closing block 9 into the closing recess 7, loosening the pulling frame 19, and the spring 13 resets and pushes the moving block 12 to drive the locking block 14 to insert into the locking groove 15, so that the inspection window frame 5 can be closed through the sealing frame 8 structure. The same principle can be used to quickly and conveniently disassemble the sealing frame 8, so that it is convenient to observe or inspect and maintain the flash tower through the inspection slot 6.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
