Description

Technical Field

[0001] This invention belongs to the field of glass crushing technology, specifically an energy-saving glass crushing and separation device for waste laboratory glass equipment. Background Technology

[0002] Waste laboratory glassware mainly consists of beakers, test tubes, volumetric flasks, ampoules, and other glass containers. When manufacturing defective products from laboratory glassware or recycling waste glass products, the glass needs to be crushed for melting and reprocessing. During recycling, it is necessary to distinguish between glass and non-glass materials; otherwise, mixing them will contaminate the molten glass, reduce the quality of the recycled product, and may even damage the furnace.

[0003] Chinese Patent Application No. 202211551581.9 discloses a laboratory glass crushing device, relating to the technical field of small glass crushing equipment. The crushing device includes a bottom receiving plate, a crushing barrel, and a crushing mechanism. The bottom receiving plate has a discharge port in the center, and a material control mechanism is fixedly connected to its top surface. A material monitoring mechanism is located at the top of the material control mechanism. A screening plate is detachably connected inside the crushing barrel. A double receiving plate is located on the bottom surface of the crushing barrel, with a material control port fixedly connected to its bottom surface. The double receiving plate is also fixedly connected to the material monitoring mechanism. Several fasteners are evenly fixedly connected to the outer top of the crushing barrel, and a feeding pipe is fixedly connected to the outer top of the crushing barrel. This invention improves safety during the crushing process by fastening the cap and the crushing barrel together. Through the coordination of the various components of the material control mechanism, it adapts to the collection of broken glass under different experimental environments, thus expanding the applicability of the device.

[0004] The aforementioned containers may have labels on their surfaces, and some may also have rubber stoppers. These labels, rubber stoppers, and other debris can become entangled in the blades of conventional shearing or hammer crushing mechanisms during crushing, thus affecting the use of the device. Furthermore, it is not possible to effectively separate glass materials and other materials, which usually require manual separation before crushing. Therefore, improvements are made to address these issues. Summary of the Invention

[0005] To address the problem mentioned in the background art that labels, rubber stoppers, and other debris become entangled in conventional shearing or hammer-type crushing mechanisms during breakage, this invention provides an energy-saving glass crushing and separation device for waste laboratory glassware.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving glass crushing and separating device for waste laboratory glassware, including a limiting mechanism, and further comprising:

[0007] A projectile mechanism, which is disposed inside the limiting mechanism and is used to place the glassware to be broken;

[0008] A driving mechanism is disposed inside the limiting mechanism and is used to drive the throwing mechanism to throw the glassware.

[0009] A collision mechanism, which is located inside the limiting mechanism and faces the throwing mechanism, is used to collide with the glassware that is thrown out and break it.

[0010] The projectile mechanism includes a projectile component and a limiting component. The projectile component is rotatably connected inside the limiting component, and the limiting component is fixedly installed inside the limiting component and sleeved on the outside of the projectile component.

[0011] Preferably, the limiting mechanism includes a first limiting chamber, a first collecting chamber, a second collecting chamber, and a second limiting chamber. The first collecting chamber and the second collecting chamber slide at opposite ends of the bottom of the first limiting chamber. The second limiting chamber is installed on the side of the first limiting chamber. The projectile assembly is rotatably connected to the first limiting chamber, and the limiting assembly is fixedly connected to the first limiting chamber.

[0012] Preferably, the driving mechanism includes a drive motor, a U-shaped connecting rod, a first connecting rod, a second connecting rod, a limiting block, and a scraper. The drive motor is installed inside the second limiting chamber, and the output shaft of the drive motor is fixedly connected to the U-shaped connecting rod. The other end of the U-shaped connecting rod is fixedly connected to the projectile assembly. The drive motor can drive the U-shaped connecting rod and the projectile assembly to rotate coaxially. One end of the first connecting rod is rotatably connected to the U-shaped connecting rod, and the other end is hinged to the second connecting rod. The limiting block is installed on the outside of the first limiting chamber, and the second connecting rod is slidably connected to the middle of the limiting block. The scraper is installed on the side of the limiting block.

[0013] Preferably, the collision mechanism includes a collision plate, a bearing component, and a connecting plate. The two ends of the collision plate are respectively hinged to the bearing component and the connecting plate. The ends of the bearing component and the connecting plate away from the collision plate are rotatably connected to the first limiting chamber. The scraper slides on the surface of the collision plate.

[0014] Preferably, the supporting component includes a supporting plate and a filter plate, the filter plate is installed in the middle of the supporting plate, the supporting plate is hinged to the collision plate, a first rubber sheet is installed between the collision plate and the supporting plate, and a second rubber sheet is installed between the collision plate and the connecting plate.

[0015] Preferably, the projectile assembly includes a connecting ring, a projectile plate, and a discharge port. The connecting ring is rotatably connected to the first limiting chamber. The projectile plate is installed at equal angles on the outside of the connecting ring. The discharge port is opened at equal angles on the surface of the connecting ring. The discharge port is located between two adjacent projectile plates. The connecting ring is closed at one end and open at the other end along its axial direction.

[0016] Preferably, the limiting component includes a limiting ring and a sealing member. The limiting ring is C-shaped, and the surface of the limiting ring has a discharge port and a movable groove. The sealing member slides inside the movable groove and can block the discharge port. When the projectile assembly rotates to project the glassware, the sealing member blocks the discharge port. When the projectile assembly reverses to push rubber or other debris, the sealing member moves to open the discharge port.

[0017] Preferably, the closure includes a closure plate, a rectangular plate, and a stop block. The closure plate slides inside the movable groove, and the rectangular plate is rotatably connected to the closure plate by a torsion spring. The stop block is installed on the top of the closure plate to prevent the rectangular plate from flipping to the side of the closure plate away from the projectile assembly.

[0018] Preferably, the bearing plate is parallel to the connecting plate, and the inclination angle of the bearing plate is less than the inclination angle of the tangent at both ends of the opening of the limiting ring.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) The present invention drives the internal glassware to rotate through the connecting ring. Under the action of centrifugal force, the glassware is directionally thrown to the surface of the collision plate through the C-shaped opening of the limiting ring. The glass is broken by high-speed collision. The impact method prevents the label or rubber stopper from getting tangled, ensuring the continuous operation of the device.

[0021] (2) In the crushing process, the first rubber sheet and the bearing plate form an inclined structure. The bearing plate vibrates with the movement of the collision plate. Glass fragments of the standard particle size fall into the first collection chamber through the filter plate and are collected. Fragments of the unqualified particle size fall back into the limiting ring under the vibration of the bearing plate. They are then thrown and collided again with the rotation of the throwing component to achieve secondary crushing and ensure the crushing effect.

[0022] (3) In this invention, the projectile assembly drives the projectile plate to reverse, and the projectile plate squeezes the rectangular plate. Under the limiting action of the stop block, the rectangular plate cannot flip to the side away from the projectile assembly, thereby driving the closed plate to slide inside the movable groove, opening the discharge port. The projectile plate continues to reverse, pushing the rubber and other impurities mixed in the glass. The impurities are discharged outside the limiting ring through the discharge port and fall into the second collection chamber, completing the separation of glass and impurities.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 10 As shown, the present invention provides an energy-saving glass crushing and separating device for waste laboratory glassware, including a limiting mechanism 100, and further comprising:

[0036] The projectile mechanism 200 is disposed inside the limiting mechanism 100 and is used to place the glassware to be broken.

[0037] The driving mechanism 300 is located inside the limiting mechanism 100 and is used to drive the throwing mechanism 200 to throw the glassware.

[0038] The collision mechanism 400 is located inside the limiting mechanism 100 and faces the throwing mechanism 200, and is used to collide with the glassware that is thrown out and break it.

[0039] The projectile mechanism 200 includes a projectile component 210 and a limiting component 220. The projectile component 210 is rotatably connected to the inside of the limiting mechanism 100, and the limiting component 220 is fixedly installed inside the limiting mechanism 100 and sleeved on the outside of the projectile component 210.

[0040] The above solution employs a nested structure of projectile component 210 and limiting component 220. Projectile component 210 is rotatably connected inside the limiting mechanism 100 to carry and project glassware. Limiting component 220 is fixedly fitted on its outer side to form protection and limitation. In conjunction with the drive mechanism 300, the projectile component 210 is driven to rotate to achieve directional projection of the glassware. The glassware is then broken by collision with the projected glassware through the collision mechanism 400. This eliminates the need for an additional high-power breaking motor, achieving energy saving and consumption reduction. At the same time, it achieves efficient glassware breaking, and the limiting component 220 can prevent glass fragments from splashing during the breaking process, ensuring the safety of equipment operation.

[0041] like Figure 2 As shown, the limiting mechanism 100 includes a first limiting chamber 110, a first collecting chamber 120, a second collecting chamber 130, and a second limiting chamber 140. The first collecting chamber 120 and the second collecting chamber 130 slide at both ends of the bottom of the first limiting chamber 110, and the second limiting chamber 140 is installed on the side of the first limiting chamber 110. The projectile assembly 210 is rotatably connected to the first limiting chamber 110, and the limiting assembly 220 is fixedly connected to the first limiting chamber 110.

[0042] like Figure 6As shown, the drive mechanism 300 includes a drive motor 310, a U-shaped connecting rod 320, a first connecting rod 330, a second connecting rod 340, a limiting block 350, and a scraper 360. The drive motor 310 is installed inside the second limiting chamber 140. The output shaft of the drive motor 310 is fixedly connected to the U-shaped connecting rod 320. The other end of the U-shaped connecting rod 320 is fixedly connected to the projectile assembly 210. The drive motor 310 can drive the U-shaped connecting rod 320 and the projectile assembly 210 to rotate coaxially. One end of the first connecting rod 330 is rotatably connected to the U-shaped connecting rod 320, and the other end is hinged to the second connecting rod 340. The limiting block 350 is installed on the outside of the first limiting chamber 110, and the second connecting rod 340 is slidably connected to the middle of the limiting block 350. The scraper 360 is installed on the side of the limiting block 350.

[0043] The above solution provides power through a drive motor 310, which drives the U-shaped connecting rod 320 to rotate coaxially with the projectile assembly 210, thereby realizing the projectile action of the glassware on the projectile assembly 210. The power transmission is direct and efficient, reducing energy loss. Through the cooperation of the first connecting rod 330, the second connecting rod 340 and the limiting block 350, the scraper 360 can drive the collision mechanism 400 to move back and forth in the tilt direction. This allows the collision mechanism 400 to quickly approach the projectile direction of the projectile assembly 210, thereby increasing the impact force and improving the glass breaking efficiency. At the same time, the movement of the collision plate 410 allows the scraper 360 to scrape the impact area of ​​the glassware, preventing debris from adhering.

[0044] like Figure 7 As shown, the collision mechanism 400 includes a collision plate 410, a bearing assembly 420 and a connecting plate 430. The two ends of the collision plate 410 are hinged to the bearing assembly 420 and the connecting plate 430 respectively. The ends of the bearing assembly 420 and the connecting plate 430 away from the collision plate 410 are rotatably connected to the first limiting chamber 110. The scraper 360 slides on the surface of the collision plate 410.

[0045] Using the above scheme: When the U-shaped connecting rod 320 rotates and drives the scraper 360 to move in the horizontal direction, the collision plate 410 is driven to move in the tilt direction and has a relative displacement with the scraper 360, which can clean up the attached debris. At the same time, the collision plate 410 is always facing the direction in which the glassware is thrown, ensuring that the thrown glassware can accurately collide with the collision plate 410, thereby improving the success rate of breaking.

[0046] like Figure 7 As shown, the support assembly 420 includes a support plate 421 and a filter plate 422. The filter plate 422 is installed in the middle of the support plate 421. The support plate 421 is hinged to the collision plate 410. A first rubber sheet 401 is installed between the collision plate 410 and the support plate 421. A second rubber sheet 402 is installed between the collision plate 410 and the connecting plate 430.

[0047] The above scheme utilizes the first rubber sheet 401 and the second rubber sheet 402 to provide a certain degree of protection, preventing debris from falling into the connection area between the collision plate 410, the connecting plate 430, and the bearing plate 421. Furthermore, the inclined shape promotes the debris to fall into the filter plate 422 area for sieving. Additionally, the bearing plate 421 moves along with the movement of the bearing plate 421, generating vibration and promoting the sieving of glass powder. Qualified particles fall through the filter plate 422 into the first collection chamber 120, while unqualified particles re-enter the limiting ring 221 under the vibration of the bearing plate 421 and are re-thrown and broken again.

[0048] like Figure 6 As shown, the projectile assembly 210 includes a connecting ring 211, a projectile plate 212, and a discharge port 213. The connecting ring 211 is rotatably connected to the first limiting chamber 110. The projectile plate 212 is installed on the outside of the connecting ring 211 at equal angles. The discharge port 213 is opened on the surface of the connecting ring 211 at equal angles. The discharge port 213 is located between two adjacent projectile plates 212. The connecting ring 211 is closed at one end and open at the other end along its axial direction.

[0049] The above solution is adopted: the connecting ring 211 serves as the main body of the load. Its structure of being closed at one end and open at the other end makes it easy to put in waste glassware. The glassware falls between the connecting ring 211 and the limiting ring 221 through the discharge port 213 and is ejected as the sealing member 222 rotates, preventing the glass from leaking from the closed end during the ejection process.

[0050] like Figure 8 As shown, the limiting component 220 includes a limiting ring 221 and a sealing member 222. The limiting ring 221 is C-shaped, and a discharge port 201 and a movable groove 202 are provided on the surface of the limiting ring 221. The sealing member 222 slides inside the movable groove 202 and can block the discharge port 201. When the projectile component 210 rotates to project the glassware, the sealing member 222 blocks the discharge port 201. When the projectile component 210 reverses to push rubber and other debris, the sealing member 222 moves to open the discharge port 201.

[0051] The above solution employs the following approach: By designing the limiting ring 221 as a C-shape to fit the annular structure of the projectile assembly 210, it provides an opening channel for the projectile of the glassware and also serves a protective function. The sealing member 222 slides inside the movable groove 202, enabling flexible switching between blocking and opening the discharge port 201. When the projectile assembly 210 rotates clockwise to project the glassware, the sealing member 222 blocks the discharge port 201 to prevent glass fragments from leaking out of the discharge port 201, ensuring the safety of the crushing process. When the projectile assembly 210 rotates counterclockwise, it pushes away impurities such as rubber mixed in the glass. At this time, the sealing member 222 moves to open the discharge port 201, facilitating the discharge of impurities from the discharge port 201, thus achieving the separation of glass and impurities. This improves crushing safety, achieves efficient separation of glass and impurities, and ensures the purity of the crushed glass.

[0052] like Figure 10 As shown, the closure 222 includes a closure plate 2221, a rectangular plate 2222, and a stop 2223. The closure plate 2221 slides inside the movable groove 202. The rectangular plate 2222 is rotatably connected to the closure plate 2221 by a torsion spring. The stop 2223 is installed on the top of the closure plate 2221 to prevent the rectangular plate 2222 from flipping to the side of the closure plate 2221 away from the projectile assembly 210.

[0053] The above scheme is adopted: the sealing plate 2221 slides inside the movable groove 202, realizing the movement of the entire sealing member 222, thereby controlling the opening and sealing of the discharge port 201; the rectangular plate 2222 and the sealing plate 2221 are rotatably connected by a torsion spring. When the projectile assembly 210 rotates forward to push the glassware to project, the projectile plate 212 pushes the rectangular plate 2222 to rotate, and the sealing plate 2221 keeps the discharge port 201 sealed; when the projectile assembly 210 rotates in reverse to push the debris, the projectile plate 212 squeezes the rectangular plate 2222. Under the limit of the stop block 2223, the rectangular plate 2222 cannot rotate, so that the entire sealing member 222 is driven to tilt upward, thereby causing the sealing plate 2221 to slide open the discharge port 201. After the debris is discharged, the entire sealing member 222 falls down with gravity, which makes it easy for the subsequent sealing member 222 to reseal the discharge port 201.

[0054] like Figure 3 As shown, the bearing plate 421 is parallel to the connecting plate 430, and the tilt angle of the bearing plate 421 is less than the tilt angle of the tangent at both ends of the opening of the limiting ring 221.

[0055] The above solution involves a bearing plate 421 with an inclination angle less than the inclination angle of the tangents at both ends of the opening of the limiting ring 221. This ensures that the collision area of ​​the collision plate 410 completely covers the opening range of the limiting ring 221, and that the collision area is located between the two scrapers 360°. This guarantees that all glassware projected by the projectile assembly 210 will collide with the collision plate 410, preventing the glassware from breaking without impact. It also prevents interference between the bearing plate 421 and the limiting ring 221, ensuring coordinated operation of all components of the equipment. This achieves the effects of improving the success rate of glass breaking, avoiding component interference, and ensuring stable operation of the equipment.

[0056] Working principle and usage process of this invention:

[0057] The waste laboratory glassware to be broken is placed into the inside of the connecting ring 211 through the open end of the connecting ring 211. The glassware falls between the connecting ring 211 and the limiting ring 221 through the drop port 213. The adjacent ejection plates 212 act as a separator and limiter for the glassware, preventing multiple glassware from squeezing each other and affecting subsequent ejection.

[0058] The drive motor 310 is started, which drives the U-shaped connecting rod 320 to rotate coaxially with the projectile assembly 210. The connecting ring 211 drives the internal glassware to rotate. Under the action of centrifugal force, the glassware is directionally projected through the C-shaped opening of the limiting ring 221 onto the surface of the collision plate 410, and the glass is broken through high-speed collision. At the same time, the rotation of the U-shaped connecting rod 320 drives the second connecting rod 340 to slide on the limiting block 350 through the first connecting rod 330, which in turn drives the scraper 360 to move on the surface of the collision plate 410. The collision plate 410 moves obliquely and generates relative displacement with the scraper 360, scraping and cleaning the glass fragments adhering to the surface of the collision plate 410. Under the hinge action of the bearing assembly 420 and the connecting plate 430, the collision plate 410 is always vertically facing the projectile direction, ensuring that all projected glassware can collide with the collision plate 410, thus improving the success rate of breaking.

[0059] During the crushing process, the first rubber sheet 401 and the bearing plate 421 form an inclined structure. The bearing plate 421 vibrates with the movement of the collision plate 410. The glass fragments after crushing are screened by the filter plate 422. Glass fragments with the standard particle size fall into the first collection chamber 120 for collection through the filter plate 422. Fragments with the unqualified particle size fall back into the limiting ring 221 under the vibration of the bearing plate 421. They are then thrown and collided again with the rotation of the throwing component 210 to achieve secondary crushing until the screening standard is met.

[0060] After the glass breaks, the drive motor 310 is started to reverse, and the projectile assembly 210 drives the projectile plate 212 to reverse. The projectile plate 212 squeezes the rectangular plate 2222. Under the limiting action of the stop block 2223, the rectangular plate 2222 cannot flip away from the side of the projectile assembly 210, thereby driving the sealing plate 2221 to slide inside the movable groove 202, so that the discharge port 201 opens. The projectile plate 212 continues to reverse, pushing the rubber and other debris mixed in the glass. The debris is discharged through the discharge port 201 outside the limiting ring 221 and falls into the second collection chamber 130, completing the separation of glass and debris. After the debris is discharged, the drive motor 310 is turned off, the sealing member 222 falls down with gravity, the sealing plate 2221 resets, and re-seals the discharge port 201.
