Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln dust collectors, in particular to stable operation equipment for metal magnesium rotary kiln bag dust collectors. Background Art

[0002] Rotary kiln In many production industries such as building materials, metallurgy, chemical industry, environmental protection, etc., rotary drum equipment is widely used to perform mechanical, physical or chemical treatment on solid materials. This type of equipment is called a rotary kiln.

[0003] Existing rotary kilns mostly use a heating furnace to perform single-point heating on the kiln body, and a large amount of dust and dirt will be generated in the process. In order to reduce pollution to the environment, bag dust collectors are often configured. However, due to the large amount of dust and dirt, the bags need to be replaced frequently. Currently, clamps are mostly used to clamp and fix the bags directly. However, the rotary kiln and the dust collector vibrate at high frequencies during operation, which can easily cause the bags to detach and fall off, which not only affects the use of the bag dust collector, but also causes environmental pollution due to the continuous operation of the rotary kiln. Utility Model Content

[0004] The utility model aims to solve the problem that the simple bag dust collector used in the rotary kiln in the prior art affects the dust removal efficiency and level, and proposes a metal magnesium rotary kiln bag dust collector stable operation device.

[0019] 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.

[0020] Reference Figure 1-Figure 3The invention discloses a stable operation device for bag dust collector of magnesium rotary kiln, comprising a dust collector body 1 and a flared end head 2 for connecting the dust bags. The installation of the dust bags is realized by fixing the flared end head 2 on the dust collector body 1.

[0021] An upper bracket 12 and a lower bracket 13 are welded to the dust removal body 1 and the flared end head 2, respectively, and a guide rod 14 movably penetrating the upper bracket 12 is integrally provided on the lower bracket 13. The upper bracket 12 and the lower bracket 13 are circumferentially equidistantly arranged in a one-to-one correspondence, and a guide through hole for slidingly fitting the guide rod 14 is opened in the upper bracket 12. The guide through hole is used to guide and support the guide rod 14, so that the flared end head 2 is fitted on the dust removal body 1 in the vertical direction.

[0022] Please refer to the instruction manual for details Figure 2 With attached Figure 3 A connecting mechanism is provided between the dust removal body 1 and the flared end head 2, and the connecting mechanism includes an extension end head 3 which is integrally connected to the lower end of the dust removal body 1 and movably sleeved in the flared end head 2, and a right-angle long cavity 4 filled with hydraulic oil is provided in the extension end head 3, a load-bearing bracket 5 is integrally welded in the right-angle long cavity 4, and an active piston 6 which resists the hydraulic oil is slidably sleeved on the load-bearing bracket 5, a booster rod 7 which extends to the lower end opening of the right-angle long cavity 4 and corresponds to the active piston 6 is integrally provided in the flared end head 2, and a driven piston long bolt 8 which resists the hydraulic oil is slidably sleeved in the upper end opening of the right-angle long cavity 4, The combined effect of gravity and the return spring 9 causes the hydraulic oil to move downward. When the booster rod 7 squeezes the active piston 6, the upwardly moving hydraulic oil squeezes the long bolt 8 of the driven piston, causing the long bolt 8 of the driven piston to extend into the limiting groove 10. A limiting groove 10 corresponding to the long bolt 8 of the driven piston is provided in the inner wall of the flared end 2, and a locking countersunk hole 11 for fixing the long bolt 8 of the driven piston in the limiting groove 10 is provided in the flared end 2. By tightening the locking screw in the locking countersunk hole 11, the long bolt 8 of the driven piston can be limited and fixed in the limiting groove 10.

[0023] The right-angle long cavity 4 is a right-angle structure, and the hydraulic oil is located between the active piston 6 and the driven piston long bolt 8. The hydraulic oil is used to strengthen the linkage effect between the active piston 6 and the driven piston long bolt 8, so that the driven piston long bolt 8 can be stably inserted into the limit slot 10.

[0024] The driven piston long bolt 8 is fixedly sleeved with a reset spring 9 welded with an upper opening of the right-angle long cavity 4. The tension of the reset spring 9 allows the driven piston long bolt 8 to reset itself when it is not squeezed by the active piston 6.

[0025] The locking countersunk hole 11 is communicated with the limiting slot 10 , and a locking screw is threadedly installed in the locking countersunk hole 11 .

[0026] It should be noted that the specific model and specifications of the dust removal body 1 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] The dust removal body 1 and the flared end 2 correspond to each other, and the guide rod 14 is vertically guided by the upper bracket 12, and the flared end 2 is vertically moved upward, so that the extended end 3 is sleeved in the flared end 2;

[0029] The booster rod 7 extends into the right-angle long cavity 4 to squeeze the active piston 6, and squeezes the driven piston long bolt 8 through the hydraulic oil, so that the driven piston long bolt 8 extends into the limit slot 10;

[0030] The locking screw is tightened through the locking counterbore 11 to lock and fix the driven piston long bolt 8 in the limiting groove 10, thereby achieving fixed installation of the bag and the dust removal body 1.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
