Technical Field

[0001] The utility model relates to the technical field of gas holders, in particular to a blast furnace gas holder. Background Art

[0002] A gas holder is a steel container for storing industrial and civil gas, and there are two types: wet gas holders and dry gas holders. A wet gas holder is a sleeve-type cylindrical structure sealed with water; a dry gas holder is a piston-type structure sealed with thin (dry) oil or flexible film.

[0029] The following further explains the present utility model in conjunction with the attached drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited do not limit the present utility model.

[0030] Refer to Figure 1 - Figure 7 As shown, a blast furnace gas holder of the present utility model includes a gas holder main body 1. A lower part on one side of the gas holder main body 1 is communicated with an inlet and outlet pipeline 3. One side of the gas holder main body 1 close to the inlet and outlet pipeline 3 is communicated with a first pipeline 5. The other end of the first pipeline 5 is fixedly connected with a first pipeline valve 4. A filtering component is arranged at the other end of the first pipeline valve 4. The inner bottom of the gas holder main body 1 is fixedly connected with a second partition board 20. The top of the second partition board 20 is fixedly connected with a first partition board 15. The middle part of the top of the first partition board 15 is rotatably connected with a rotating rod 19. The bottom of the first partition board 15 is fixedly connected with a motor 23, and the output end of the motor 23 is fixedly connected with the rotating rod 19. A bottom oil sump 21 in the cabinet is arranged between the adjacent sides of the second partition board 20 and the gas holder main body 1. The other end of the rotating rod 19 is fixedly connected with a perforated scraping plate 22, and the perforated scraping plate 22 corresponds to the bottom oil sump 21 in the cabinet. One end of the inlet and outlet pipeline 3 close to the piston 14 is fixedly connected with an arc-shaped baffle 18. One side of the arc-shaped baffle 18 close to the gas holder main body 1 is fixedly connected with an arc-shaped drainage plate 17, and the arc-shaped drainage plate 17 is fixedly connected with the gas holder main body 1. Drainage grooves 25 are fixedly opened on both sides of the top of the arc-shaped drainage plate 17.

[0031] During operation, when the device starts to run, gas enters the interior of the gas holder main body 1 through one end of the inlet and outlet pipe 3 that is far from the gas holder main body 1. Under pressure, the piston 14 is pushed upward. At the same time, a part of the sealing oil slowly flows down along the inner wall of the gas holder main body 1, and then flows into the bottom oil sump 21 inside the gas holder and is collected. When the sealing oil on the upper side of the inlet and outlet pipe 3 inside the gas holder main body 1 flows down, it will be blocked by the arc-shaped diversion plate 17 and move along the arc surface of the arc-shaped diversion plate 17 to both sides. With the cooperation of the diversion groove 25, the sealing oil is guided into the bottom oil sump 21 inside the gas holder, preventing the sealing oil from flowing down along the outer wall of the inlet and outlet pipe 3 to the bottom of the gas holder main body 1 and reducing the loss of the sealing oil. Among them, multiple openings are provided on the surface of the perforated scraper 22, which facilitates the passage of the sealing oil inside the bottom oil sump 21 while blocking sediments and impurities.

[0032] Furthermore, as Figure 2 shown, the filtering assembly includes a filter pipe 8, the filter pipe 8 is fixedly connected to the first pipeline valve 4, a filter net 13 is fixedly connected to the inner side of the filter pipe 8, a sewage discharge pipe 10 communicates with the middle of the filter pipe 8, and one end of the sewage discharge pipe 10 penetrates and is fixedly connected to the filter net 13, and the other end of the sewage discharge pipe 10 is fixedly connected to a sewage discharge pipe valve 12.

[0033] During operation, when performing the cyclic filtration of the sealing oil, the sealing oil stored inside the bottom oil sump 21 is pumped out by the liquid extraction pump 9 and transported into the filter pipe 8, and the impurities and dirt mixed in the sealing oil are filtered through the filter net 13 inside the filter pipe 8.

[0034] Furthermore, as Figure 2 shown, a first three-way valve 11 communicates with the side of the filter pipe 8 away from the first pipeline valve 4. The upper port of the first three-way valve 11 is fixedly connected to a liquid extraction pump 9, and the output end of the liquid extraction pump 9 is fixedly connected to a second three-way valve 7.

[0035] During operation, when performing the cyclic filtration of the sealing oil, adjust the first three-way valve 11 to open the port connecting the filter pipe 8 and close the other port. When performing the work of cleaning impurities, adjust the first three-way valve 11 to close the port connecting the filter pipe 8 and open the other port.

[0036] Furthermore, as Figure 1 shown, the port of the second three-way valve 7 close to the inlet and outlet pipe 3 is fixedly connected to a backwashing pipe 6, and the other end of the backwashing pipe 6 communicates with the filter pipe 8.

[0037] During operation, when it is necessary to clean the impurities and dirt inside the filter net 13, adjust the second three-way valve 7 to open the port connecting the backwashing pipe 6 to facilitate the entry of the subsequent cleaning water source.

[0038] Furthermore, as Figure 1 shown, a return pipe 2 is fixedly connected to the port on the side of the second three-way valve 7 away from the inlet and outlet pipe 3, and the other end of the return pipe 2 is communicated with the main body 1 of the gas holder.

[0039] During operation, the main body 1 of the gas holder and the second three-way valve 7 are connected through the return pipe 2. When the filtered sealing oil enters the second three-way valve 7, it flows back into the main body 1 of the gas holder through the return pipe 2.

[0040] Furthermore, as Figure 3 shown, a piston 14 is arranged at the upper part inside the main body 1 of the gas holder, and the piston 14 cooperates with 1.

[0041] During operation, the piston 14 cooperates with the sealing oil to prevent gas leakage.

[0042] Furthermore, as Figure 7 shown, a traveling wheel 24 is fixedly connected to the middle part of the outer circle of the rotating rod 19. A traveling track 16 is opened at the top of the first partition plate 15, and the traveling wheel 24 corresponds to the traveling track 16.

[0043] During operation, when the rotating rod 19 rotates, the cooperation of the traveling wheel 24 and the traveling track 16 makes the rotation process of the rotating rod 19 smoother and more stable. At the same time, the traveling wheel 24 can also provide a certain supporting force for the rotating rod 19. Through the traveling track 16, the traveling wheel 24 is smoother during the rotation process following the rotating rod 19, avoiding deflection during the rotation of the traveling wheel 24.

[0044] Furthermore, as Figure 5 shown, the arc-shaped baffle 18 corresponds to the second partition plate 20, and the second three-way valve 7 and the first three-way valve 11 cooperate with each other.

[0045] During operation, through the blocking of the arc-shaped baffle 18, the sealing oil flowing down from the arc-shaped drainage plate 17 is prevented from splashing outside the bottom oil sump 21 of the cabinet. By adjusting the valves of the second three-way valve 7 and the first three-way valve 11, the two states of filtration and backwashing are switched.

[0046] Working principle: When the device starts to operate, gas enters the interior of the gas holder main body 1 through one end of the inlet and outlet pipe 3 that is far from the gas holder main body 1. Under pressure, the piston 14 is pushed upward. At the same time, a part of the sealing oil slowly flows down along the inner wall of the gas holder main body 1 and then flows into the bottom oil sump 21 inside the gas holder and is collected. When the sealing oil flowing down on the upper side of the inlet and outlet pipe 3 inside the gas holder main body 1 is blocked by the arc-shaped drainage plate 17, it moves along the arc surface of the arc-shaped drainage plate 17 to both sides, and under the cooperation of the diversion groove 25, the sealing oil is guided into the bottom oil sump 21 inside the gas holder. At the same time, under the action of the arc-shaped baffle 18, the sealing oil on this side can be prevented from splashing outside the bottom oil sump 21. At the same time, the motor 23 is started to drive the rotating rod 19 to rotate, and further drive the perforated scraper 22 to move in the bottom oil sump 21 through the rotating rod 19, scrape off the impurities and dirt deposited inside the bottom oil sump 21, and push them to the vicinity of the port of the first pipe 5. At the same time, the liquid extraction pump 9 is started. Under the action of the liquid extraction pump 9, the sealing oil inside the bottom oil sump 21 is driven to pass through the first pipe 5 and the first pipe valve 4 into the filter screen 13, and the impurities and dirt are filtered out by the filter screen 13. The filtered sealing oil passes through the first three-way valve 11 and, under the action of the liquid extraction pump 9, passes through the second three-way valve 7 and the return pipe 2 and returns to the top of the piston 14. When the impurities remaining in the filter screen 13 during filtration accumulate to a certain amount, the first pipe valve 4 is closed, the drain pipe valve 12 is opened, and the first three-way valve 11 is adjusted to close the port close to the filter pipe 8 and open the port on the other side. The second three-way valve 7 is adjusted to close the port connected to the return pipe 2 and open the port connected to the backwash pipe 6. The port of the first three-way valve 11 far from the filter pipe 8 is connected to the cleaning water source. At the same time, the liquid extraction pump 9 is started. Under the action of the liquid extraction pump 9, the cleaning water source enters the liquid extraction pump 9 through the first three-way valve 11, and then enters the interior of the filter pipe 8 through the second three-way valve 7 and the backwash pipe 6 to perform backwashing on the inner side of the filter screen 13. The impurities and dirt washed out are discharged to the external environment through the drain pipe 10 and the drain pipe valve 12.

[0047] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
