Description

Technical Field

[0001] The utility model relates to the technical field related to smelting furnaces, in particular to an environmentally friendly smelting furnace. Background Art

[0002] During the smelting operation in the smelting furnace, a large amount of harmful dust such as metal oxides, non-metal oxides, organic substances, etc. will be generated, which will pollute the outside air. Therefore, it is necessary to set a dust collecting mechanism outside the smelting furnace to deal with these dusts. The internal filtering structure of the existing dust collecting mechanism still adopts a more traditional detachable setting. The dust can be blocked by the filtering structure. The detachable setting can collect the dust blocked by the filtering mechanism. Although this is convenient for collecting dust, the workers will waste a lot of time and energy in the process of continuous disassembly and installation of the filtering mechanism, and the workers will come into contact with the dust, which poses a great safety hazard. For this reason, we have proposed an environmentally friendly smelting furnace. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: an environmentally friendly smelting furnace, comprising a furnace body 1 and a dust collector 2, a furnace cover 11 is fixedly installed on the upper end surface of the furnace body 1 through a thread, an air inlet pipe 12 is fixedly installed on the upper end surface of the furnace cover 11 and is communicated with the inner cavity thereof, a dust guide pipe 21 is fixedly installed between the dust collector 2 and the upper end surface of the furnace cover 11 and is communicated with the inner cavities of both, a partition 22 is fixedly installed in the dust collector 2, the dust guide pipe 21 is fixedly connected to the upper end surface of the partition 22, and an exhaust pipe 201 and a dust exhaust pipe 201 are fixedly installed on the upper and lower sides of the outer periphery of the dust collector 2, respectively. 02, a partition 22 is arranged between the exhaust pipe 201 and the dust exhaust pipe 202, and a plurality of through cavities 23 are opened at equal intervals on the upper end surface of the partition 22, a sealing plate 24 is fixedly installed in one of the through cavities 23, and filter screens 25 are fixedly installed in the remaining through cavities 23, a rotating rod 26 is rotatably installed on the lower side of the inner cavity of the dust collector 2, and a guide pipe 27 connected with the lower end of the dust guide pipe 21 is fixedly installed on the upper end surface of the rotating rod 26, the guide pipe 27 is U-shaped, and a movable cover 28 matching the size of the through cavity 23 is fixedly installed on the other side of the upper end of the guide pipe 27.

[0025] Specifically, a rotating rod 26 is provided to drive the guide pipe 27 to rotate on the lower end surface of the partition 22, so that the movable cover 28 is aligned with the lower ends of each filter screen 25 in turn. Since the upper end of the guide pipe 27 is connected to the dust guide pipe 21, when the movable cover 28 is aligned with the corresponding filter screen 25, the air direction at the filter screen 25 is from bottom to top, thereby blocking the dust in the air discharged upward from the inside of the guide pipe 27. If the remaining filter screens 25 are not aligned with the movable cover 28, the air direction in the remaining filter screens 25 is from top to bottom, thereby the dust blocked by the lower end surface of the filter screen 25 can be blown downward into the dust exhaust pipe 202, and the dust filtered by the device can be collected through the dust exhaust pipe 202.

[0026] In another embodiment provided by the present invention, a liquid guide ring 3 is fixedly installed on the upper end of the outer wall of the dust collector 2, and the liquid guide ring 3 is arranged on the periphery of the dust guide pipe 21. A plurality of nozzles 31 are fixedly installed on the upper side of the inner cavity of the dust collector 2. The upper end of each nozzle 31 is interconnected with the inner cavity of the liquid guide ring 3, and a liquid guide pipe 32 is fixedly installed on the outer end of the liquid guide ring 3.

[0027] Specifically, by setting a liquid guide ring 3 at the upper end of the outer wall of the dust collector 2, and setting a nozzle 31 connected to the liquid guide ring 3 at the upper side of the inner cavity of the dust collector 2, in conjunction with the liquid guide pipe 32, the cleaning liquid can be regularly and evenly sprayed to the dust collector 2, so as to clean the inner wall of the dust collector 2 and the surface of the filter screen 25;

[0028] A sealing plate 24 is disposed in one of the through cavities 23 . During the cleaning process, the alignment between the movable cover 28 and the sealing plate 24 can prevent the cleaning liquid from entering the movable cover 28 and the guide tube 27 , thereby preventing contamination inside the guide tube 27 .

[0029] In another embodiment provided by the present invention, the dust exhaust pipe 202 is arranged in an L shape, and a positioning plate 42 is fixedly installed on the lower end of the outer wall of the dust exhaust pipe 202, and a movable rod 41 is plugged and installed on the lower end of the rotating rod 26, and a positioning frame 43 plugged with the positioning plate 42 is fixedly installed on the periphery of the movable rod 41. A plurality of through cavities 23 are evenly spaced and distributed in a circular array on the periphery of the dust guide pipe 21. The positioning plate 42 and the positioning frame 43 adopt a polygonal structure, and the number of sides of the two is equal to the number of through cavities 23. An insertion cavity 4 is opened on the lower end surface of the rotating rod 26, and the movable rod 41 is plugged and installed in the insertion cavity 4. A concave cavity 46 is opened on the upper end surface of the movable rod 41, and a spring 47 is fixedly installed between the bottom surface of the inner cavity of the concave cavity 46 and the upper end surface of the insertion cavity 4, a sliding cavity 44 is opened on the periphery of the insertion cavity 4, and a sliding rod 45 slidingly matched with the sliding cavity 44 is fixedly installed between the positioning frame 43 and the movable rod 41.

[0030] Specifically, when rotating the rotating rod 26 to drive the guide tube 27 to rotate and adjust the position of the movable cover 28, since the positioning plate 42 and the positioning frame 43 adopt a polygonal structure and the number of sides of the two is equal to the number of the through cavity 23, the guide tube 27 and the movable cover 28 can be positioned through the plug-in effect between the positioning plate 42 and the positioning frame 43, avoiding looseness at the connection between the movable cover 28 and the filter screen 25, thereby avoiding dust from overflowing from the gap between the two.

[0031] Working principle: pull the movable rod 41 downward to separate the positioning frame 43 and the positioning plate 42 from each other, release the restriction effect on the movable rod 41 and the rotating rod 26, stretch the spring 47, and then rotate the movable rod 41. The rotating movable rod 41 can drive the rotating rod 26 on the outer periphery of the movable rod 41 to rotate with it through the sliding cooperation between the slide rod 45 and the slide cavity 44, and then drive the guide tube 27 to rotate on the lower end surface of the partition 22, so that the movable cover 28 and the lower end position of the corresponding filter screen 25 are aligned with each other. Subsequently, release the movable rod 41, and under the action of the spring 47 restoring the deformation, the movable rod 41 can be driven to reset upward, so that the positioning frame 43 and the positioning plate 42 are re-inserted, and then the guide tube 27 and the movable cover 28 can be positioned;

[0032] Connect the air intake pipe 12 to the external air pump, start the external air pump, and inject air into the furnace body 1 through the air intake pipe 12, and then inject the dust and air in the furnace body 1 into the dust collector 2 through the dust guide pipe 21, and then guide the air and dust to the filter 25 from bottom to top through the internal guide pipe 27 and the movable cover 28 of the dust collector 2. The dust in the air can be blocked at its lower end surface through the filter 25, and the air passing through the filter 25 expands at the upper end surface of the partition 22, and part of it is discharged to the outside through the exhaust pipe 201 for subsequent air treatment, while the other part passes through the remaining filters 25 from top to bottom, and the dust blocked on the lower end surfaces of these filters 25 can be blown into the dust exhaust pipe 202, and the dust can be recovered through the dust exhaust pipe 202;

[0033] In addition, by respectively arranging a liquid guide ring 3 and a nozzle 31 which are interconnected at the upper end of the outer wall and the top surface of the inner cavity of the dust collector 2, and cooperating with the liquid guide tube 32, the cleaning liquid can be regularly and evenly sprayed onto the dust collector 2 to clean the inner wall of the dust collector 2 and the surface of the filter screen 25.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
