Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of rock wool recycling technology, and more specifically, to a waste rock wool recycling device for electric furnaces. Background Technology
[0002] An electric furnace is a heating furnace that converts electrical energy into heat to heat workpieces. Electric furnaces can be classified into resistance furnaces, induction furnaces, electric arc furnaces, plasma furnaces, electron beam furnaces, etc. During the use of electric furnaces, a large amount of waste rock wool is generated. Rock wool, also known as mineral wool, is an insulating material made by smelting basalt or other ores and then fiberizing it. It is a common insulating material used in construction and industry, possessing good heat insulation and sound absorption properties. Recycling equipment is used to recycle and reuse this waste rock wool.
[0003] In existing waste rock wool recycling devices, waste rock wool is crushed and then screened to remove impurities and improve its purity. However, the screening mechanism inside the recycling device is relatively simple, usually using a sieve plate to screen the crushed waste rock wool. During the screening process, the sieve plate is prone to clogging, which affects the screening effect of waste rock wool. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a waste rock wool recycling device for electric furnaces, which solves the technical problem that the internal screening mechanism of the recycling device in related technologies / prior technologies is relatively simple, and usually uses a sieve plate to screen the crushed waste rock wool. During the screening process, the sieve plate is prone to clogging, which affects the screening effect of waste rock wool.
[0005] According to one aspect, at least one embodiment of this disclosure provides a waste rock wool recycling device for electric furnaces, including a processing box and a screening structure, the screening structure comprising:
[0006] The vibration mechanism is located inside the processing box;
[0007] A screening frame is installed inside the vibration mechanism. A sieve plate is provided at the bottom of the screening frame. The screening frame and the sieve plate vibrate synchronously when they follow the vibration mechanism.
[0008] The collision component is installed inside the processing box. When the screening box vibrates synchronously with the vibration mechanism, the screening box collides with the collision component.
[0009] In order to cause the screening frame to vibrate and shake evenly, there are two sets of vibration mechanisms, and the two sets of vibration mechanisms are arranged symmetrically.
[0010] To cause the filter box to vibrate and shake, the vibration mechanism includes:
[0011] A guide post is installed inside the processing box, and several extrusion rings are sleeved on the guide post;
[0012] The transmission frame is vertically movably sleeved on the guide post, and its inner side is connected to the outer side of the screening frame;
[0013] A vibration motor is mounted on the upper side of the transmission frame and moves vertically synchronously with the transmission frame;
[0014] A spring is provided, and several springs are sleeved on the guide post. The two ends of the spring are respectively connected to the compression ring and the transmission frame. When the transmission frame moves vertically, it will compress or stretch the spring.
[0015] In order to clean up the residue inside the filter box, a baffle is provided for vertical movement inside the filter box.
[0016] To enhance the anti-clogging effect on the sieve plate, the collision component consists of an L-shaped plate and a collision block, wherein the collision block is trapezoidal in shape.
[0017] To ensure the stability of the transmission frame during movement, the processing box is equipped with a slide rail in the shape of a square, and the slide rail is slidably connected to the transmission frame.
[0018] To ensure that the crushed waste rock wool can enter the screening frame, a collection hopper is provided inside the processing box, and the lower part of the collection hopper is located inside the screening frame.
[0019] To allow the screened waste rock wool to roll onto the conveying mechanism, a guide plate is installed inside the processing box. The guide plate is inclined, and the angle between the guide plate and the processing box is °.
[0020] To prevent the filter box from colliding directly with the collision block, a buffer pad is provided on the lower side of the collision block.
[0021] To ensure the stability of the baffle during movement, a square block is installed on the inner side of the screening frame, and a square groove is provided on the outer side of the baffle. The baffle moves vertically along the square block through the square groove.
[0022] The beneficial effects of the embodiments disclosed herein are as follows:
[0023] In this invention, while the vibration mechanism drives the screening frame and the screen plate to vibrate and shake, the screening frame will collide with the collision component, so that the waste rock wool blocked on the screen plate can be shaken off under the action of the collision force, thereby achieving anti-clogging treatment of the screen plate, reducing the probability of the screen plate being blocked by waste rock wool, and ensuring the screening effect of the screen plate.

[0038] like Figures 1-4As shown, this invention discloses an embodiment of a waste rock wool recycling device for electric furnaces, including a processing box 1 and a screening structure. In this embodiment, the screening structure includes a vibration mechanism 2, a screening frame 3, a sieve plate 4, and a collision element 5. Compared with the simpler screening mechanism inside the recycling device in the prior art, which usually uses a sieve plate to screen the crushed waste rock wool, the sieve plate is prone to clogging during the screening process, affecting the screening effect of the waste rock wool. In this invention, the vibration mechanism 2 drives the screening frame 3 and the sieve plate 4 to vibrate and shake, so that the sieve plate 4 can speed up the screening when screening the crushed waste rock wool, reducing the probability of clogging of the sieve plate 4. During the vibration and shaking process, the screening frame 3 will collide with the collision element 5, which can further enhance the anti-clogging effect of the sieve plate 4 and ensure the screening effect of the waste rock wool.
[0039] The processing box 1 is equipped with a conveying mechanism 10 and a crushing mechanism 11. The upper side of the processing box 1 is connected to a feeding pipe 12. The waste rock wool that needs to be recycled enters the crushing mechanism 11 inside the processing box 1 through the feeding pipe 12. The crushing mechanism 11 crushes the waste rock wool. After being screened by the screening structure, the crushed waste rock wool rolls onto the conveying mechanism 10 and is then conveyed out of the processing box 1 by the conveying mechanism 10.
[0040] Vibration mechanism 2 is installed inside processing box 1. Screening frame is installed inside vibration mechanism 2. There are two sets of vibration mechanism 2, which are symmetrically arranged. Screening frame 3 has a screen plate 4 at its inner bottom. Screening frame 3 and screen plate 4 vibrate synchronously when they follow vibration mechanism 2. Vibration mechanism 2 is composed of guide column 201, transmission frame 202, vibration motor 203 and spring 204. Slide rail 7 is installed inside processing box 1. Slide rail 7 is U-shaped. Slide rail 7 and transmission frame 202 are slidably connected. When vibration motor 203 runs, transmission frame 202 will vibrate accordingly. Transmission frame 202 will move along guide column 201 and slide rail 7. Under the influence of spring 204 sleeved on guide column 201, transmission frame 202 will vibrate, thereby driving screening frame 3 and screen plate 4 to vibrate.
[0041] The filter box 3 is equipped with a vertically movable baffle 6 inside. The baffle 6 is equipped with a fixing component and a handle. A square block is installed on the inner side of the filter box 3, and a square groove is opened on the outer side of the baffle 6. The baffle 6 moves vertically along the square block through the square groove. When it is necessary to open the baffle 6, the fixing component can be removed from the positioning between the filter box 3 and the baffle 6. Then, the baffle 6 can be pulled upward along the square block by the handle, thereby opening the baffle 6.
[0042] The collision element 5 is installed inside the processing box 1. The collision element 5 is composed of an L-shaped plate 501 and a collision block 502. The collision block 502 is trapezoidal in shape. A buffer pad 503 is provided on the lower side of the collision block 502. When the screening frame 3 vibrates synchronously with the vibration mechanism 2, the screening frame 3 collides with the collision element 5. After the screening frame 3 and the collision element 5 collide, the debris blocking the screen holes on the screen plate 4 will be shaken off, thereby achieving the anti-clogging treatment of the screen plate 4.
[0043] The processing box 1 is equipped with a collection hopper 8. The lower part of the collection hopper 8 is located inside the screening frame 3. The processing box 1 is equipped with a guide plate 9, which is inclined and the angle between the guide plate 9 and the processing box 1 is 55°. The crushed waste rock wool falls into the collection hopper 8 and is then transported to the screening frame 3. The waste rock wool that has been screened by the screen plate 4 inside the screening frame 3 will fall onto the guide plate 9 and then roll onto the conveying mechanism 10.
[0044] Working principle: Waste rock wool to be recycled enters the crushing mechanism 11 inside the processing box 1 through the feeding pipe 12. The crushing mechanism 11 crushes the waste rock wool. The crushed waste rock wool rolls down into the screening frame 3 through the collection hopper 8. At this time, the vibration motor 203 is started. The vibration motor 203 drives the transmission frame 202 to vibrate. The transmission frame 202 moves along the guide column 201 and the slide rail 7. While the transmission frame 202 vibrates, it shakes under the action of the spring 204. At the same time, it drives the screening frame 3 and the screen plate 4 to vibrate. During the vibration of the screening frame 3 and the screen plate 4, the screening frame 3 will collide with the collision part 5. When they collide, the waste rock wool blocking the screen plate 4 will be shaken off, thereby achieving the anti-clogging treatment of the screen plate 4.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications or substitutions should be covered within the scope of the claims of this disclosure.
