Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a burner protective cover. Background Art

[0002] In industries such as cement, inorganic chemical industry, calcination, and mineral processing, the burner protective cover is an important core device. The burner mixes fuel and air through an air flow channel, and then ignites through an ignition device to form a flame of a certain shape for calcining materials. The burner protective cover can make the flame shape and temperature distribution reasonable, forming strong and uniform thermal radiation.

[0003] Most traditional burner protective covers are directly fixed to the periphery of the burner when in use. When using the protective cover, it needs to be correspondingly fixed to the burner. The flame at the opening of the burner is relatively dispersed, affecting the heating efficiency of the burner and increasing the energy loss to a certain extent.

[0004] However, in the actual use process of traditional devices, they are often used one by one. It is not easy to adjust the protective cover according to the sizes of different burners to achieve multi-purpose use, and it is not easy to adjust the ventilation holes on the protective cover, so it is difficult to achieve long-term protection of the burner. Therefore, a burner protective cover needs to be proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages in the prior art that it is not easy to adjust the protective cover according to the sizes of different burners and it is not easy to adjust the ventilation holes on the protective cover, and to propose a burner protective cover.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A burner protective cover includes a load-bearing block and a burner. Symmetrically sliding plates are arranged inside the load-bearing block in a sliding manner. The protruding parts of the two sliding plates are commonly threadedly connected to a first threaded rod, and the first threaded rod is threadedly connected to a first screw nut. The number of the first screw nuts is two groups. Connecting columns are symmetrically and fixedly connected to the upper part of the load-bearing block. Third opening grooves are opened inside the two connecting columns. Second threaded rods are slidably arranged inside the third opening grooves. First connecting blocks are fixedly connected to one ends of the two second threaded rods close to the sliding plates. A first cover body is commonly fixedly connected to one sides of the two first connecting blocks far away from the third opening grooves;

[0008] One end of the first cover body away from the burner is symmetrically and fixedly connected with a second connecting block. The two second connecting blocks are jointly and slidably connected with a second cover body at the end away from the first cover body. A plurality of first ventilation grooves are formed inside the first cover body, and a plurality of second ventilation grooves are formed inside the second cover body. The first ventilation grooves and the second ventilation grooves correspond to each other. One side of the first cover body close to the first threaded rod is symmetrically and fixedly connected with a first fixing block. One side of the second cover body close to the first threaded rod is symmetrically and fixedly connected with a plurality of second fixing blocks. The first fixing block and the second fixing blocks are jointly threadedly connected with a third threaded rod. By rotating the second cover body, the front and rear positions of the first ventilation grooves and the second ventilation grooves are made to correspond. At this time, oxygen will enter the protective cover from them.

[0009] The above technical solution further includes:

[0010] First opening grooves are symmetrically formed on the outer side of the load-bearing block, and second opening grooves are symmetrically formed on the inner side of the load-bearing block. The two second opening grooves are both slidably connected with the sliding plate, and the two first opening grooves are both slidably connected with the sliding plate.

[0012] The size of the second threaded rod is adapted to the size of the third opening groove, and the size of the protruding part of the sliding plate is adapted to the size of the first opening groove.

[0013] A plurality of the first ventilation grooves are evenly distributed circumferentially inside the first cover body, and a plurality of the second ventilation grooves are evenly distributed circumferentially inside the second cover body. The sizes of the first ventilation grooves and the second ventilation grooves are adapted to each other. When the burner stops working, rotate the second cover body to stagger the positions of the first ventilation grooves and the second ventilation grooves, and the protective cover will separate the burner from the outside world.

[0014] The present utility model has the following beneficial effects:

Connecting columns 8 are symmetrically and fixedly connected to the upper part of the load-bearing block 1. Third opening grooves 9 are opened inside both of the two connecting columns 8. Second threaded rods 10 are slidably arranged inside the third opening grooves 9. One end of each of the two second threaded rods 10 close to the sliding plate 5 is fixedly connected to a first connecting block 12. A first cover body 13 is fixedly connected to the side of the two first connecting blocks 12 away from the third opening grooves 9.

[0027] First opening grooves 3 are symmetrically opened on the outer side of the load-bearing block 1. Second opening grooves 4 are symmetrically opened on the inner side of the load-bearing block 1. The two second opening grooves 4 are slidably connected to the sliding plate 5 respectively. The two first opening grooves 3 are slidably connected to the sliding plate 5 respectively. The second threaded rods 10 are threadedly connected to second screw caps 11. The two second screw caps 11 are both on the side of the connecting column 8 away from the sliding plate 5.

[0028] A sliding groove 18 is opened on the side of the second cover body 16 close to the first cover body 13. The size of the sliding groove 18 is adapted to the size of the protruding part of the second connecting block 15. The size of the second threaded rod 10 is adapted to the size of the third opening groove 9. The size of the protruding part of the sliding plate 5 is adapted to the size of the first opening groove 3. The second connecting block 15 is slidably connected to the sliding groove 18.

When the burner 2 is working, the second cover 16 is slidably connected to the first cover 13 through the second connection blocks 15. It is necessary to rotate the second cover 16 to a suitable position. When it is rotated until the first ventilation grooves 14 and the second ventilation grooves 17 are horizontally corresponding front and back, rotate the third threaded rod 21. The third threaded rod 21 is threadedly connected to the first fixing blocks 19 and the second fixing blocks 20, so as to ensure the locking of the second cover 16 in this position. External oxygen will enter the protective cover through the first ventilation grooves 14 and the second ventilation grooves 17, so as to provide stable oxygen for the burner. When the burner 2 is not working, it is necessary to rotate the second cover 16 to a suitable position again. When it is rotated until the first ventilation grooves 14 and the second ventilation grooves 17 are not horizontally corresponding front and back, rotate the third threaded rod 21. The third threaded rod 21 is threadedly connected to the first fixing blocks 19 and the second fixing blocks 20, so as to ensure the locking of the second cover 16 in this position. At this time, the protective cover will separate the burner from the outside world, so as to realize the long-term protection of the burner.
