[0027] Example 1
[0028] like Figure 1 and Figure 2 As shown:
[0029] An environmentally friendly charging device suitable for a high-level silo of an electric furnace comprises a main body 1, a feeding end plate 2 with a feeding port 21 is installed on the top of the main body 1, a dust suction pipe 3 is installed on the side of the main body 1, and a discharge port 16 is arranged at the bottom of the main body 1.
[0030] The main body 1 is detachably mounted on the top of the high-position silo 6, and the main body 1 is connected to the top of the high-position silo 6 by bolts. A lifting ring 11 is installed on the top of the main body 1 to realize the overall lifting of the feeding device, which is convenient for the maintenance and cleaning of the inside of the high-position silo 6.
[0031] The feed port 21 is arranged in coordination with the outlet of the hopper 5 .
[0032] A grid plate 4 is installed at the bottom of the main body 1 near the discharge port 16 to filter materials and prevent debris and large pieces of materials from falling into the high-level silo 6.
[0033] The grating plate 4 is slidably connected to the inner wall of the main body 1. A retaining ring is arranged at the bottom of the inner wall of the main body 1. The grating plate 4 is arranged above the retaining ring. The retaining ring is used to prevent the grating plate 4 from sliding down and prevent the grating plate 4 from separating from the main body 1.
[0034] The grating plate 4 can also be detachably connected to the inner wall of the main body 1, and the grating plate 4 can be detachably installed inside the grating plate 4 by bolts.
[0035] The grating plate 4 is slidably connected or detachably connected to the inner wall of the main body 1, so that the operator can replace the grating plate 4 conveniently and remove the sundries and bulk materials blocked by the grating plate 4 conveniently.
[0036] The dust suction pipe 3 is connected to the dust removal system, and can suck the dust generated during the material falling process into the dust removal system at the rear end.
[0037] The discharge port 16 is arranged in coordination with the inlet port at the top of the high-level silo 6 .
[0038] Example 2
[0039] like Figure 3 As shown, the feed end plate 2 at the top of the main body 1 is replaced by an upper inclined plate 12 , which is inclined inward, and the feed port 21 is opened in the middle of the upper inclined plate 12 , and the outer peripheral edge of the upper inclined plate 12 is higher than the height of the feed port 21 .
[0040] The outer peripheral edge of the upper inclined plate 12 is connected to the main body 1 , and the upper inclined plate 12 and the main body 1 enclose a dust collecting space.
[0041] During the discharge process, the solid material falls, and the dust generated during the falling process floats to the dust collecting space. The setting of the dust collecting space facilitates dust collection.
[0042] A plurality of first auxiliary pipes 31 are installed near the outer edge of the upper inclined plate 12. The plurality of first auxiliary pipes 31 are connected to the dust suction pipe 3 and are used to suck the dust in the dust collecting space into the dust removal system at the rear end. After the first auxiliary pipe 31 sucks, a negative pressure is formed in the dust collecting space, and the dust continuously gathers in the dust collecting space and is then sucked by the first auxiliary pipe 31. The dust inside the main body 1 is sucked together by the dust suction pipe 3 and the first auxiliary pipe 31 to avoid dust deposition in the feeding device and the workshop.
[0043] The other technical solutions are the same as those in Example 1 and will not be described in detail here.
[0044] Example 3
[0045] like Figure 4 As shown, a mixer is provided in the main body 1 and is located above the grid plate 4 .
[0046] The mixer includes a stirring shaft 71 , both ends of which are rotatably connected to the side walls of the main body 1 , and one end of the stirring shaft 71 passes through the side wall of the main body 1 and extends to the outside to connect to a stirring motor 73 , which is installed on the outer wall of the main body 1 .
[0047] The outer wall of the stirring shaft 71 is provided with a spiral blade 72 , and the lowest point of the spiral blade 72 is arranged at a position close to the top surface of the grid plate 4 .
[0048] The stirring shaft 71 drives the spiral blade 72 to rotate under the drive of the stirring motor 73. When the grid plate 4 is blocked, the spiral blade 72 can push the debris and large pieces of material on the grid plate 4 away from the blocked position, so that normal materials fall down, and the debris and large pieces of material can be transported to the inner edge position of the main body 1 as the spiral blade 72 rotates.
[0049] If a blockage occurs at the inner edge of the main body 1, the spiral blades 72 can also push debris and large pieces of material away from the blockage, making it easier for the material to fall.
[0050] A sealing plate is provided at the rotation connection between the stirring shaft 71 and the side wall of the main body 1 to effectively prevent dust in the main body 1 from leaking out through the rotation connection, thereby avoiding pollution of the workshop environment and the external atmospheric environment.
[0051] The other technical solutions are the same as those in Example 1 and will not be described in detail here.
[0052] Example 4
[0053] like Figure 5 As shown, a feed pipe 22 corresponding to the feed port 21 is installed on the top surface of the main body 1 , and the feed pipe 22 extends upward to be connected to the outlet of the hopper 5 .
[0054] A rubber sealing ring 23 is installed on the top of the inner wall of the feed pipe 22. The outlet of the feeding hopper 5 is plugged into or connected to the feed pipe 22 by bolts. The rubber sealing ring 23 is arranged between the outer wall of the outlet of the feeding hopper 5 and the inner wall of the feed pipe 22 to isolate dust and prevent dust from leaking from the gap at the connection between the feed pipe 22 and the feeding hopper 5.
[0055] A plurality of second auxiliary pipes 32 are also provided in the feed pipe 22, and the plurality of second auxiliary pipes 32 are connected to the dust suction pipe 3, and are used to suck the dust in the feed pipe 22 into the dust removal system at the rear end. After the second auxiliary pipe 32 sucks, a negative pressure is formed in the feed pipe 22, and the dust floats upward and gathers into the feed pipe 22, and is then sucked by the second auxiliary pipe 32. The dust inside the main body 1 is sucked together by the dust suction pipe 3 and the second auxiliary pipe 32, so as to avoid dust deposition in the feeding device and the workshop.
[0056] The other technical solutions are the same as those in Example 1 and will not be described in detail here.
[0057] Example 5
[0058] like Figure 6 As shown, a feed pipe 22 corresponding to the feed port 21 is installed on the top surface of the main body 1, and a connecting pipe 25 is installed above the feed pipe 22. The feed pipe 22 and the connecting pipe 25 are coaxially arranged, and the feed pipe 22 and the connecting pipe 25 are connected by a telescopic pipe 24.
[0059] The connecting pipe 25 is connected to the outlet of the feeding hopper 5, and a rubber sealing ring 23 is installed on the top of the inner wall of the connecting pipe 25. The outlet of the feeding hopper 5 and the connecting pipe 25 are plugged in or connected by bolts. The rubber sealing ring 23 is arranged between the outer wall of the outlet of the feeding hopper 5 and the inner wall of the connecting pipe 25 to isolate dust and prevent dust from leaking from the gap at the connection between the connecting pipe 25 and the feeding hopper 5.
[0060] The telescopic tube 24 has a certain telescopic range, which can ensure that the feeding device is always connected to the feeding hopper 5 when the feeding hopper 5 and the feeding device are relatively moving or vibrating, thereby preventing the feeding hopper 5 from separating from the feeding device during the feeding process, resulting in spillage of materials.
[0061] The grating plate 4 in this embodiment is tiltedly arranged inside the main body 1 , and a debris removal channel 14 is opened at a position of the side wall of the main body 1 near the lowest end of the grating plate 4 .
[0062] During the falling process of the materials, the debris and large pieces of materials are blocked by the grid plate 4 and slide to the lowest end of the grid plate 4. The operator can set a gate in the debris removal channel 14 to remove the debris and large pieces of materials to prevent the grid plate 4 from being blocked and affecting the filtering effect of the grid plate 4.
[0063] A lower inclined plate 13 is provided at the bottom of the main body 1 . The lower inclined plate 13 is inclined inwardly. The discharge port 16 is opened in the middle of the lower inclined plate 13 . The outer peripheral edge of the lower inclined plate 13 is higher than the height of the discharge port 16 .
[0064] A vibration motor 8 is installed on the outer surface of the lower inclined plate 13, and a connecting seat 15 is provided on the outer wall of the main body 1 near the bottom. A spring damper 81 is provided between the connecting seat 15 and the top surface of the high-level silo 6, and the top of the spring damper 81 is connected to the connecting seat 15, and the bottom of the spring damper 81 is detachably connected to the top of the high-level silo 6.
[0065] By setting a vibration motor 8, the main body 1 vibrates, and the dust deposited between the materials is shaken out, which facilitates the suction of the dust collection pipe 3, improves the dust collection efficiency, enhances the dust collection effect, and also facilitates the debris and large pieces of material on the grid plate 4 to slide to the lowest end of the grid plate 4. At the same time, through vibration, the material at the blocked part of the grid plate 4 falls down, avoiding affecting the filtering of the grid plate 4.
[0066] A material distribution pipe 17 is provided at the lower end of the discharge port 16 , and the material distribution pipe 17 extends to the interior of the high-level silo 6 to ensure that the material is smoothly transported to the high-level silo 6 .
[0067] The other technical solutions are the same as those in Example 1 and will not be described in detail here.
[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
