Description

Technical Field

[0001] This utility model relates to the field of electric furnace shell production technology, specifically to a waste material collection device for electric furnace shell production. Background Technology

[0002] As is well known, various types of waste materials, such as metal scraps, shavings, and plastic residues, are generated during the production of electric furnace shells. To achieve resource recycling and maintain a clean production environment, waste material collection devices are widely used. Currently, most waste material collection devices are equipped with filter structures to classify and screen waste materials of different specifications and intercept impurities to prevent pipe blockage. However, in the use of existing waste material collection devices, the filter structure is prone to clogging. Metal shavings and fine particles in the waste materials from the production of electric furnace shells easily adhere to the surface of the filter structure. Over time, the accumulated waste materials will gradually block the pores of the filter structure, preventing the waste materials from passing through the filter structure smoothly and affecting the normal operating efficiency of the collection device.

[0003] To solve the problem of filter clogging, existing technologies mostly use mechanical scraping. The mechanical scraping device uses a motor to drive a scraper to contact the surface of the filter structure and scrape off the attached residue. However, the continuous friction of the scraper can easily damage the filter structure and shorten its service life. Summary of the Invention

[0004] Technical problems to be solved

[0005] In order to overcome the problem that the filter structure is easily damaged due to the contact cleaning of the existing waste material collection device for electric furnace shell production, this utility model provides a waste material collection device for electric furnace shell production with non-contact cleaning effect.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste material collection device for electric furnace shell production, comprising a body, two sets of filter screens slidably disposed inside the body, the filter screens being used for grading and screening and intercepting impurities, two sets of horizontal plates fixedly disposed with the filter screens, two sets of pulleys rotatably disposed on one side of the horizontal plates, and two sets of adjusting components respectively disposed on both sides of the body. Each adjusting component includes a fixed plate fixedly disposed on the outside of the body, two sets of sliders slidably disposed inside the fixed plate, a top block parallel to the pulleys on one side of each slider, the top block having a triangular vertical cross-section, a moving column on one side of each slider, a push plate slidably disposed on the outside of the moving column, a threaded tube rotatably disposed inside the fixed plate, a sleeve threaded onto the outside of the threaded tube, a threaded hole inside the sleeve matching the threaded tube's outer thread, one side of the sleeve being fixedly disposed with a movable shaft slidably disposed within the push plate, a mounting column on one side of the fixed plate, and a driving component disposed within the mounting column.

[0008] Preferably, the drive assembly includes a rotary motor disposed in a mounting column, the output end of the rotary motor being keyed to a rotating column, a first bevel gear being disposed at the end of the rotating column away from the rotary motor, the first bevel gear meshing with two sets of second bevel gears, a connecting rod being disposed on the side of the second bevel gear away from the first bevel gear, and the end of the connecting rod away from the second bevel gear being fixedly disposed to a threaded tube.

[0009] Furthermore, a connecting shaft is provided inside the horizontal plate, and a connecting block is provided at one end of the connecting shaft. The two sets of connecting blocks are respectively fixed to the two sets of filter screens, and the connecting blocks are located inside the machine body.

[0010] Furthermore, two sets of central shafts are provided on the side of the horizontal plate away from the machine body, and the pulleys are rotatably located on the outside of the central shafts.

[0011] In a further embodiment, a balance bar is slidably disposed inside the connecting shaft, and the balance bar is fixedly disposed inside the machine body.

[0012] Based on the aforementioned scheme, a first spring is provided on one side of the slider, and the end of the first spring away from the slider is located inside the fixed plate.

[0013] Furthermore, based on the aforementioned scheme, two sets of blocking plates are provided on the outer side of the slider, with the two sets of blocking plates located on both sides of the fixed plate.

[0014] Furthermore, based on the aforementioned scheme, one end of the threaded tube is fixedly disposed with the middle of the bearing, and the bearing is fixedly disposed inside the fixed plate.

[0015] Beneficial effects

[0016] This residual material collection device for the electric furnace shell production uses a combination of a top block and a pulley. When the top block swings back and forth, it drives the filter screen to swing up and down by pushing the pulley. This causes the filter screen to vibrate during the swing, making it easier for residual material attached to the filter screen to fall off. This avoids clogging caused by residual material accumulation and also avoids contact cleaning, reducing filter screen wear and extending its service life. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figures 1-8 A waste material collection device for electric furnace shell production includes a body 1. Two sets of filter screens 4 are slidably connected inside the body 1. The two sets of filter screens 4 have different pore sizes. The upper filter screen 4 uses a square mesh size to quickly intercept larger metal scraps, while the lower filter screen 4 has a smaller pore size, specifically designed to capture small metal fragments and plastic dust. Grading and screening are achieved through size differences. Two sets of connecting blocks 6 are welded between the two sets of filter screens 4. One side of the connecting block 6 is welded to a connecting shaft 10 slidably connected inside the body 1. A horizontal plate 5 is welded to the outside of the connecting shaft 10, and the horizontal plate 5 is located on the outside of the body 1. Two sets of central shafts 9 are welded to the side of the horizontal plate 5 away from the body 1. A pulley 8 is rotatably mounted on the outside of the central shaft 9. Two sets of balance bars 11 are bolted inside the body 1. The connecting shaft 10 is slidably connected to the outside of the balance bar 11, thereby maintaining the balance of the connecting shaft 10 during movement and preventing misalignment of the connecting shaft 10. A second spring 7 is fixedly connected to both sides of the connecting shaft 10. The end of the second spring 7 away from the connecting shaft 10 is fixedly installed inside the body 1. Thus, when the connecting shaft 10 is pushed, the two sets of second springs 7 will be squeezed and stretched by the connecting shaft 10 respectively. When the connecting shaft 10 is no longer pushed, the second spring 7 will bounce the connecting shaft 10 back, thereby causing the connecting shaft 10 to drive the filter screen 4 to swing up and down by driving the connecting block 6. An adjustment component 2 is provided on both sides of the body 1. A drive component 3 is provided inside the adjustment component 2, and one side of the drive component 3 and one side of the adjustment component 2 are fixedly installed.

[0028] First, refer to Figures 1 to 4In this embodiment, the adjustment component 2 includes a fixed plate 201 fixedly disposed on the outside of the body 1. A mounting post 207 is welded to the bottom of the fixed plate 201. Two sets of sliders 205 are slidably connected inside the fixed plate 201. A top block 203 is welded to the top of each slider 205. The top block 203 has a triangular vertical cross-section, and its top contacts the outside of the pulley 8. One side of the slider 205 is fixedly connected to a moving post 204 slidably connected inside the fixed plate 201. A push plate 206 is slidably connected to the outside of the fixed plate 201. Two sets of bearings 212 are fixedly installed inside. A threaded tube 213 is provided in the middle of the bearing 212. A sleeve 210 is screwed on the outside of the threaded tube 213. A threaded hole that matches the thread on the outside of the threaded tube 213 is opened inside the sleeve 210. When the threaded tube 213 rotates, it will drive the sleeve 210 to move linearly. The end of the threaded tube 213 away from the bearing 212 is fixedly connected to one side of the drive assembly 3. A movable shaft 202 is provided on the outside of the sleeve 210. The end of the movable shaft 202 away from the sleeve 210 is slidably connected to the inside of the push plate 206.

[0029] Then, refer to Figures 2 to 4 In this embodiment, to prevent the push plate 206 from being misaligned, an anti-detachment block 211 is provided on the outside of the moving column 204. The anti-detachment block 211 is located on the side of the push plate 206 away from the fixed plate 201. Thus, the push plate 206 can be blocked by the anti-detachment block 211, thereby preventing the push plate 206 from being misaligned. The anti-detachment block 211 is a circular anti-detachment block, and the anti-detachment block 211 can be replaced by a square or rectangular anti-detachment block. The width of both sides of the anti-detachment block 211 must be greater than the width of the push plate 206.

[0030] Secondly, see Figure 3 In this embodiment, a first spring 209 is provided on one side of the slider 205. The end of the first spring 209 away from the slider 205 is located inside the fixed plate 201. Thus, when the slider 205 is pushed, the first spring 209 will be squeezed by the slider 205. When the slider 205 is no longer pushed, the first spring 209 will drive the top block 203 to move back by bouncing the slider 205 back, so that the top block 203 quickly returns to the initial position and disengages from the pulley 8.

[0031] Again, see Figures 2 to 3 In this embodiment, two sets of baffle plates 208 are provided on the outer side of the slider 205. The two sets of baffle plates 208 are located on both sides of the fixed plate 201, thereby restricting the movement of the slider 205 and preventing the slider 205 from becoming unbalanced or misaligned during movement, thus ensuring the normal use of the device.

[0032] When the threaded tube 213 rotates, it will cause the outer threaded sleeve 210 to move laterally. The movement of the sleeve 210 will drive the push plate 206 to move by driving the movable shaft 202. The movement of the push plate 206 will push the moving column 204 to move. The movement of the moving column 204 will drive the top block 203 to move by driving the slider 205. This will cause the top block 203 to push the pulley 8 to move upward. When the threaded tube 213 reverses, the movable shaft 202 will push the push plate 206 to move back. At this time, the first spring 209 will drive the top block 203 to move back by springing the slider 205. This will cause the top block 203 to quickly return to its initial position and disengage from the pulley 8.

[0033] Finally, see Figure 3 , Figure 5 and Figure 6 In this embodiment, the drive assembly 3 includes a rotary motor 301 disposed within the mounting column 207. The rotary motor 301 is a bidirectional motor, and its output end can rotate forward or backward. The output end of the rotary motor 301 is keyed to a rotating column 302. A first bevel gear 304 is disposed at the end of the rotating column 302 away from the rotary motor 301. The first bevel gear 304 meshes with two sets of second bevel gears 305. A connecting rod 303 is disposed on the side of the second bevel gear 305 away from the first bevel gear 304. The connecting rod 303 is located away from the second bevel gear 305. One end is fixedly installed with the threaded tube 213. When the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the rotating column 302 to rotate. The rotation of the rotating column 302 will drive the first bevel gear 304 to rotate. The rotation of the first bevel gear 304 will drive the two sets of second bevel gears 305 to rotate. The rotation of the second bevel gears 305 will drive the connecting rod 303 to rotate. The rotation of the connecting rod 303 will drive the threaded tube 213 to rotate. When the output end of the rotary motor 301 reverses, the connecting rod 303 will drive the threaded tube 213 to reverse.

[0034] The residual material collection device for the production of the electric furnace shell, through the cooperation between the top block 203 and the pulley 8, will drive the filter screen 4 to swing up and down by pushing the pulley 8 when the top block 203 swings back and forth. This causes the filter screen 4 to vibrate during the swing, making it easier for the residual material attached to the filter screen 4 to fall off, avoiding blockage caused by the accumulation of residual material. At the same time, it avoids the contact cleaning method, reduces the wear of the filter screen 4, and extends its service life.

[0035] Working principle:

[0036] When using this waste material collection device for electric furnace shell production, first place the device in the desired location. Then, the waste material accumulated on the vibrating filter screen 4 is collected. Specifically, the operation is as follows: Turn on the rotary motor 301 so that its output drives the rotating column 302 to rotate back and forth. The rotation of the rotating column 302 will drive the first bevel gear 304 to rotate, which in turn will drive the two sets of second bevel gears 305 to rotate. The rotation of the second bevel gears 305 will drive the connecting rod 303 to rotate, which in turn will drive the threaded tube 213 to rotate. When the threaded tube 213 rotates, it will cause the outer threaded sleeve 210 to move laterally. The movement of the sleeve 210 will push the push plate by moving the movable shaft 202. When the push plate 206 moves, the movement of the push plate 206 will push the moving column 204 to move. The movement of the moving column 204 will drive the top block 203 to move by driving the slider 205, thereby causing the top block 203 to push the pulley 8 to move upward. When the threaded tube 213 reverses, the movable shaft 202 will push the push plate 206 to move back. At this time, the first spring 209 will drive the top block 203 to move back by bouncing the slider 205, thereby causing the top block 203 to quickly return to the initial position and disengage from the pulley 8. When the pulley 8 swings up and down, it will drive the horizontal plate 5 to swing up and down by driving the central shaft 9. The swing of the horizontal plate 5 will drive the connecting block 6 to swing by driving the connecting shaft 10. The swing of the connecting block 6 will drive the two sets of filter screens 4 to swing, thereby shaking off the residual material accumulated on the filter screens 4.
