DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-Figure 6, an energy-saving and environmentally friendly device for an iron-making blast furnace, comprising a purification box 1, a water tank 2 installed on the purification box 1, an air inlet pipe 3 and an air outlet pipe 4 installed on both sides of the purification box 1, a purification chamber 101 is opened on the inner wall of the purification box 1, a plurality of partitions 8 are fixedly connected to the inner wall of the purification chamber 101, a plurality of support frames 10 are slidably connected to the inner wall of the purification chamber 101, a plurality of diamond plates 9 are fixedly connected to one side of the plurality of support frames 10, and the outer walls of the plurality of diamond plates 9 are respectively slidably connected to the inner walls of the adjacent partitions 8, a transmission mechanism is connected to the outer wall of the purification box 1, a moving component is connected to the output end of the transmission mechanism, and the other end of the moving component passes through the purification box 1, the plurality of partitions 8 and the plurality of support frames 10, a plurality of cleaning components are connected to the inner wall of the water tank 2 on one side close to the purification chamber 101, and the other ends of the plurality of cleaning components pass through the inner wall of the water tank 2 and are respectively connected to the plurality of support frames 10.

[0025] The energy-saving and environmental protection device for an iron-making blast furnace in the utility model is similar in structure to the existing energy-saving and environmental protection device for an iron-making blast furnace, such as the coal-injection energy-saving and environmental protection device for an iron-making blast furnace disclosed in the patent with publication number CN217025992U. The main improvement of the utility model is that when the user uses the purification box 1 to treat the smoke and dust of the iron-making blast furnace, the support frame 10 can be driven to move by controlling the moving assembly through the transmission mechanism at regular intervals, and then the empty space of the partition 8 can be cleaned through a number of diamond plates 9, thereby avoiding the blockage caused by smoke and dust adhesion. Figures 1 to 6 As shown, when the iron-making blast furnace energy-saving and environmental protection device in the utility model is used, the air inlet pipe 3 is first connected to the external iron-making blast furnace, and then the water tank 2 is connected to the external water resource, and then the flue gas is purified normally. When the external smoke enters the purification chamber 101 from the air inlet pipe 3, it will first contact the frontmost partition 8 and pass through the empty space inside the partition 8. The smoke passing through will be weighted by the water sprayed from the upper water tank 2, so that most of the smoke will slide down from the bottom of the partition 8, but some of the smoke will still pass through and enter the next partition 8, until the smoke passes through all the partitions 8, and the harmful substances inside have been completely purified, and then the clean gas will be discharged to the outside from the air outlet pipe 4.

[0026] After the smoke is weighted by the water sprayed from the water tank 2, although most of the sewage will be discharged, some of the sewage will still adhere to the wall of the empty space of the partition 8. Over time, it is likely to cause adhesion until the empty space is completely blocked. In order to avoid such a situation, the air intake pipe 3 can be closed (or not closed, not specifically limited) at regular intervals, and then the switch of the transmission mechanism is turned on by an external controller. After the transmission mechanism is started, it will drive the moving component to move left and right inside the purification chamber 101. When the moving component moves left and right, it will drive the connected support frame 10 to move left and right. While moving, several diamond plates 9 on one side of the support frame 10 will be inserted into the empty space of the adjacent partition 8, so that the sludge and impurities in the empty space of the partition 8 can be pushed out. The pushed out sludge and impurities will fall into the collection box below the purification chamber 101 due to their own gravity, and then the collection box can be pulled out to clean up this part of the sludge and impurities, which is convenient and quick.

[0027] While the support frame 10 moves left and right, the top of the support frame 10 will clean the multiple water spraying ports below the water tank 2 through the cleaning assembly, which can also avoid the problem of clogging and adhesion of the water spraying ports.

[0028] Please refer to Figure 2-Figure 4 The transmission mechanism includes a support seat 6 and a hydraulic rod 5, one end of the support seat 6 is fixedly connected to the outer wall of the purification box 1, the other end of the support seat 6 is fixedly connected to the outer wall of the hydraulic rod 5, and the output end of the hydraulic rod 5 is connected to the moving component.

[0029] More specifically, when the empty space of the partition 8 needs to be cleaned, the switch of the hydraulic rod 5 is turned on by the external controller. After the hydraulic rod 5 is started, it remains stable under the support of the support seat 6 and will not tilt or deviate. Therefore, the output end of the hydraulic rod 5 will drive the moving component to move left and right, thereby completing the subsequent movement of the support frame 10, diamond plate 9, etc.

[0030] Please refer to Figure 2-Figure 4 The moving assembly includes a moving rod 13 and a plurality of auxiliary sliding rods 12, one end of the moving rod 13 is fixedly connected to the output end of the hydraulic rod 5, the other end of the moving rod 13 penetrates the purification box 1, a plurality of partitions 8 and a plurality of support frames 10, and the moving rod 13 is slidably connected to the purification box 1 and the plurality of partitions 8, the moving rod 13 is fixedly connected to the plurality of support frames 10, both ends of the plurality of auxiliary sliding rods 12 are fixedly connected to the two sides of the inner wall of the purification chamber 101, and the plurality of auxiliary sliding rods 12 penetrate the plurality of partitions 8 and the plurality of support frames 10, and are slidably connected to the plurality of partitions 8 and the plurality of support frames 10.

[0031] More specifically, when the hydraulic rod 5 is started, the output end of the hydraulic rod 5 pulls the moving rod 13 to move left and right. While the moving rod 13 moves left and right, it will pull several support frames 10 connected to the surface together and move left and right inside the purification chamber 101, and then can be moved together through the diamond plate 9, thereby completing the purpose of cleaning the empty space of the partition 8.

[0032] The auxiliary sliding bars 12 can prevent the support frames 10 and the diamond-shaped plates 9 from being offset and tilted during the movement.

[0033] Please refer to Figure 2 , Figure 3 and Figure 6 The cleaning assembly includes a supporting block 7, a lifting rod 14, a cleaning block 16, a reset member and a suction member. A water outlet 701 is provided on the bottom surface and side wall of the supporting block 7. The side of the supporting block 7 close to the water outlet 701 is fixedly connected to the bottom surface of the inner wall of the water tank 2. One end of the lifting rod 14 passes through the upper surface of the supporting block 7 and is fixedly connected to the upper surface of the cleaning block 16. One end of the cleaning block 16 away from the lifting rod 14 passes through the water tank 2 and is slidably connected to the inner wall of the water tank 2. The upper surface of the cleaning block 16 is connected to the reset member, and the other end of the reset member is connected to the upper surface of the water outlet 701. The bottom surface of the cleaning block 16 is connected to the suction member, and the other end of the suction member is connected to the upper surface of the supporting frame 10.

[0034] More specifically, when cleaning is not performed, the lifting rod 14 and the cleaning block 16 are located inside the water tank 2 under the action of the reset member, and are not located in the water spray port below the water tank 2, so they will not block the normal water spraying.

[0035] When it is necessary to clean the empty space of the partition 8, the support frame 10 moves to one side. When the suction member above the support frame 10 moves to the water spray port under the water tank 2, it will attract the other part of the suction member below the cleaning block 16, so that the cleaning block 16 can be pulled downward. At the same time, the reset member is stretched. At the moment the cleaning block 16 is pulled down, the sludge, impurities, etc. located in the water spray port are pushed down into the purification chamber 101. When the support frame 10 passes through the water spray port under the continued action of the hydraulic rod 5, the cleaning block 16 lacks suction force, so it will be pushed back to its original position again under the action of the reset member, and will not affect the subsequent water spraying.

[0036] Please refer to Figure 6 The reset member includes a reset spring 15 , the upper end of the reset spring 15 is fixedly connected to the upper surface of the water outlet 701 , the lower end of the reset spring 15 is fixedly connected to the upper surface of the cleaning block 16 , and the reset spring 15 is sleeved on the outer wall of the lifting rod 14 .

[0037] More specifically, by setting the reset member as a reset spring 15, the characteristics of the reset spring 15 can enable the cleaning block 16 to be pushed above the water outlet in the absence of attraction. After being attracted, the height of the cleaning block 16 can be compressed to lower the height of the cleaning block 16, making it easier for the cleaning block 16 to clean the inside of the water outlet.

[0038] Please refer to Figure 4-Figure 6 The attracting member includes an active magnet 11 and a passive magnet 17. One end of the active magnet 11 is fixedly connected to the upper surface of the support frame 10, and one end of the passive magnet 17 is fixedly connected to the inner wall of the cleaning block 16. The active magnet 11 and the passive magnet 17 attract each other.

[0039] More specifically, by setting the attracting member as the active magnet 11 and the passive magnet 17, the active magnet 11 and the passive magnet 17 can attract each other when they are close to each other, and do not interfere with each other when they are separated. It is worth mentioning that the attraction force of the active magnet 11 and the passive magnet 17 must be greater than the elastic force of the reset spring 15, but less than the push and pull force of the hydraulic rod 5.

[0040] Please refer to Figure 4-Figure 6 The active magnet 11 and the passive magnet 17 are respectively embedded in the supporting frame 10 and the cleaning block 16.

[0041] More specifically, the active magnet 11 and the passive magnet 17 are arranged inside the support frame 10 and the cleaning block 16, which can firstly avoid occupying the external space inside the support frame 10 and the cleaning block 16; and secondly, the connectivity with the support frame 10 and the cleaning block 16 can be strengthened.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may 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 shall be included in the protection scope of the present invention.
