Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and specifically discloses a device for quickly cleaning mud clogged air vents. Background Technology

[0002] During blast furnace shutdown and maintenance, in order to reduce heat loss inside the furnace and prevent gas leakage, water-soaked mud is usually used to seal the tuyeres. Due to the large amount of mud and its hardness, hexagonal steel with pointed ends is used to seal the tuyeres before restarting the blast furnace. The operation takes about 30 to 40 minutes and requires the cooperation of multiple people.

[0003] This method has the following disadvantages:

[0004] 1. Using hexagonal steel to thoroughly clean the water-soaked mud makes it easy for the mud to be blown into the blast furnace after re-airing, which affects blast furnace production to some extent. In addition, the contact area between the hexagonal steel and the water-soaked mud is small, and the operation time for personnel is long.

[0005] 2. Cleaning requires workers to push and pull the hexagonal steel while repeatedly rotating it, which is labor-intensive.

[0006] Therefore, a device for quickly clearing mud blockage from air vents is needed to solve this problem. Utility Model Content

[0007] This utility model proposes a device for quickly cleaning mud clogged air vents. The device uses a cleaning cylinder with a pointed tip to clean the mud in the water, resulting in a large contact area and fast cleaning speed. Furthermore, when the operator pushes or pulls the connecting rod, the cleaning cylinder can rotate automatically, reducing the labor intensity of the operator.

[0008] This invention is implemented as follows: a device for quickly cleaning mud from an air vent includes a cleaning cylinder. A probe is fixedly connected to the outer wall of the cleaning cylinder, and a sleeve is fixedly connected to the other end of the probe. Two circumferentially distributed spiral grooves are formed through the outer wall of the sleeve. A connecting rod extending to the outside of the sleeve is slidably connected inside the sleeve. Two symmetrically distributed shafts located inside the sleeve are fixedly connected to the outer wall of the connecting rod. Rollers are rotatably connected to the outer walls of both shafts, and the two rollers are slidably connected to the two spiral grooves respectively. A spring is movably installed inside the sleeve, and a traction mechanism is provided at the other end of the connecting rod.

[0009] To facilitate pushing and pulling the connecting rod, as a preferred embodiment of the quick-cleaning air vent blockage device of this utility model, the traction mechanism includes a traction rod that passes through and is slidably connected inside the connecting rod, and a fixing bolt is threadedly connected to the other end of the connecting rod, with the threaded end of the fixing bolt abutting against the traction rod.

[0010] To facilitate the installation of the traction rod, as a preferred embodiment of this utility model for quickly clearing mud blockage in air vents, the outer wall of the connecting rod is provided with a hexagonal hole, and the traction rod is slidably connected to the inside of the connecting rod through the hexagonal hole.

[0011] To prevent the rollers from coming off, as a preferred embodiment of this invention for a quick cleaning device for vent blockage, a limiting plate is fixedly connected to the outer wall of the connecting shaft.

[0012] To facilitate the removal of blockages, the cleaning cylinder, preferably the end furthest from the probe rod, is inclined in a preferred embodiment of this invention for quickly removing blockages from air vents.

[0013] To facilitate increasing the friction between the traction rod and the worker's hand, the traction rod, preferably made of hexagonal steel, is preferred in this invention's rapid air vent cleaning device.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This rapid air vent cleaning device, through the cooperation of connecting rods, connecting shafts, rollers, sleeves and spiral grooves, allows the cleaning cylinder to rotate automatically when the operator pushes or pulls the connecting rod, thus cleaning the water-soaked mud. This reduces the labor intensity of the operators. The cleaning cylinder, with its pointed tip, has a large contact area and a fast cleaning speed. Attached Figure Description

[0023] Please see Figure 1-4 A device for quickly clearing blockages in air vents includes a cleaning cylinder 1. A probe rod 2 is fixedly connected to the outer wall of the cleaning cylinder 1. A sleeve 3 is fixedly connected to the other end of the probe rod 2. Two circumferentially distributed spiral grooves 4 are formed through the outer wall of the sleeve 3. A connecting rod 5 extending to the outside of the sleeve 3 is slidably connected inside the sleeve 3. Two symmetrically distributed connecting shafts 9 located inside the sleeve 3 are fixedly connected to the outer wall of the connecting rod 5. Rollers 10 are rotatably connected to the outer walls of the two connecting shafts 9. The two rollers 10 are slidably connected to the two spiral grooves 4 respectively. A spring 12 is movably installed inside the sleeve 3. A traction mechanism is provided at the other end of the connecting rod 5.

[0024] In this embodiment: When cleaning the mud from the air vent, the cleaning cylinder 1 is inserted into the mud-blocked area of ​​the air vent through the probe rod 2. Two workers hold the two ends of the traction rod 7 and push it towards the mud-blocked area. The traction rod 7 drives the connecting rod 5 to move towards the mud-blocked area, which in turn drives the probe rod 2 and the cleaning cylinder 1 to move towards the mud-blocked area through the spring 12. When the cleaning cylinder 1 contacts the mud-blocked area, the connecting rod 5 continues to move towards the mud-blocked area, which drives the sleeve 3 to rotate through the roller 10 and the spiral groove 4, thereby driving the probe rod 2 and the cleaning cylinder 1 to rotate and clean the mud-blocked area. When the roller 10 moves to the end of the spiral groove 4, the connecting rod 5 continues to drive the probe rod 2 and the cleaning cylinder 1 to move towards the mud-blocked area and remove the mud-blocked area. The cleaning cylinder 1, which is equipped with a pointed tip, cleans the mud-blocked area, resulting in a large contact area with the mud-blocked area and a fast cleaning speed. In addition, when the workers push and pull the connecting rod 5, the cleaning cylinder 1 can be automatically rotated, reducing the labor intensity of the workers.

[0025] As a technical optimization of this utility model, the traction mechanism includes a traction rod 7 that passes through and is slidably connected inside the connecting rod 5, and a fixing bolt 8 is threadedly connected to the other end of the connecting rod 5, with the threaded end of the fixing bolt 8 abutting against the traction rod 7.

[0026] In this embodiment: the traction rod 7 is inserted into the hexagonal hole 6 inside the connecting rod 5, and the fixing bolt 8 is rotated. The threaded end of the fixing bolt 8 moves inward to fix the traction rod 7.

[0027] As a technical optimization of this utility model, a hexagonal hole 6 is provided through the outer wall of the connecting rod 5, and the traction rod 7 is slidably connected to the inside of the connecting rod 5 through the hexagonal hole 6.

[0028] In this embodiment: a hexagonal hole 6 is made through the outer wall of the connecting rod 5 to facilitate the insertion of the traction rod 7 into the connecting rod 5.

[0029] As a technical optimization of this utility model, the outer wall of the connecting shaft 9 is fixedly connected to the limiting plate 11.

[0030] In this embodiment, a limiting plate 11 is fixedly connected to the outer wall of the connecting shaft 9 to prevent the roller 10 from coming off.

[0031] As a technical optimization of this utility model, the end of the cleaning cylinder 1 away from the probe rod 2 is inclined.

[0032] In this embodiment, by setting the end of the cleaning cylinder 1 away from the probe rod 2 as an inclined plane, it is easier to clean the blockage.

[0033] As a technical optimization of this utility model, the traction rod 7 is made of hexagonal steel.

[0034] In this embodiment, by setting the traction rod 7 as a hexagonal steel, the friction between the traction rod 7 and the worker's hand is increased.

[0035] The working principle and usage process of this utility model are as follows: When cleaning mud from a vent, firstly, the cleaning cylinder 1 is inserted into the mud-blocked area of ​​the vent using the probe 2. Then, two workers hold both ends of the traction rod 7 and push it towards the mud-blocked area. The traction rod 7 drives the connecting rod 5 to move towards the mud-blocked area, which in turn drives the probe 2 and the cleaning cylinder 1 to move towards the mud-blocked area via the spring 12. When the cleaning cylinder 1 contacts the mud-blocked area, the connecting rod 5 continues to move towards the mud-blocked area, which drives the sleeve 3 to rotate via the roller 10 and the spiral groove 4, thereby driving the probe 2 and the cleaning cylinder 1 to rotate. The roller 10 rotates to clean the blockage. When the roller 10 moves to the end of the spiral groove 4, the connecting rod 5 continues to drive the probe rod 2 and the cleaning cylinder 1 to move towards the blockage, chiseling off the blockage. Then the cleaning cylinder 1 is removed from the blockage, and the cleaned blockage is poured out. This operation is repeated until all the blockage at the air vent is cleaned. The cleaning cylinder 1, which is equipped with a pointed tip, cleans the blockage. It has a large contact area with the blockage and a fast cleaning speed. When the staff pushes and pulls the connecting rod 5, it can drive the cleaning cylinder 1 to rotate automatically, reducing the labor intensity of the staff.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
