Description

Technical Field

[0001] This application relates to the field of glass manufacturing technology, and more specifically, to a crushing device and method for easily absorbing moisture glass raw materials. Background Technology

[0002] In glass production, premixed additives are often added to improve glass properties. The formulation of premixed additives is an indispensable part of the borosilicate glass manufacturing process, and the raw materials required for premixing often determine certain key physicochemical properties of the finished glass. Since premixed additives are often materials used in small quantities in the glass raw materials or whose compositional fluctuations require precise control, accurate weighing and premixing are essential. However, for some raw materials that are highly hygroscopic, prone to clumping and agglomeration, traditional manual crushing or crushing with conventional crushers can lead to poor crushing results, uneven particle size, and excessive dust. Furthermore, because the amount of additives used is small, after the daily requirement is met through manual or machine crushing, the remaining raw materials can clump again. In addition, substances such as sodium nitrate in the additive formulation are inherently flammable and explosive. In the enclosed environment of the batching workshop, when the dust concentration exceeds a certain level, an explosion is highly likely.

[0003] Therefore, for such raw materials that are highly hygroscopic and pose certain risks, it is necessary to design an online crushing method that allows for controllable crushing weight and dust control. Summary of the Invention

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0041] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0044] Figures 1 to 8 This invention illustrates a schematic embodiment of a crushing device for moisture-absorbing glass raw materials, as shown in the present application. Figures 1 to 8As shown, this application discloses a crushing device for easily absorbing moisture glass raw materials, including: a crushing chamber 100, a weighing chamber 200, a discharge chamber 300, a first spiral feeder 400, and a second spiral feeder 500, all of which are sealed structures. The crushing chamber 100, the weighing chamber 200, and the discharge chamber 300 are arranged sequentially from top to bottom.

[0045] The crushing chamber 100 is equipped with crushing components.

[0046] Weighing chamber 200 is equipped with weighing components.

[0047] The lower discharge end of the discharge hopper 300 is connected to the glass mixing and preparation room. Since the crushing process is performed on individual raw materials, after each individual raw material is weighed and discharged, it needs to be mixed in a specific ratio to ultimately produce a mixed raw material for glass processing. In this embodiment, the lower discharge end of the discharge hopper 300 is directly connected to the glass mixing and preparation room, thus eliminating the need for a traditional crusher (which, due to mechanical and process requirements, is usually not designed to be installed in the glass mixing and preparation room) to transport the raw materials into the glass mixing and preparation room using an intermediate transport container / belt. This avoids the problem of the crushed raw material re-exposing to moisture and caking after leaving the sealed equipment.

[0048] The first screw feeder 400 is sealed to the crushing chamber 100 and the weighing chamber 200, with the feeding direction facing the weighing chamber 200, and is used to transport the crushed raw materials to the weighing chamber 200. The second screw feeder 500 is sealed to the weighing chamber 200 and the discharge chamber 300, with the feeding direction facing the discharge chamber 300, and is used to transport a fixed amount of crushed raw materials from the weighing chamber 200 to the discharge chamber 300. For the sealing between the various structures, welding seals or flange connections can be used at rigid metal connections, while flexible materials can be used for sealing at flexible connections.

[0049] In this embodiment, the crushing chamber 100, weighing chamber 200, discharge chamber 300, first screw feeder 400, and second screw feeder 500 form a sealed equipment unit, which can complete the crushing, weighing, and quantitative transportation of raw materials in one go. The entire processing is carried out within the sealed equipment unit, which on the one hand avoids the problem of raw materials absorbing air moisture and re-caking, ensuring accurate weighing and use of raw materials. On the other hand, it also limits the dust problem during the raw material crushing process, improving the working environment for workers. Moreover, this embodiment utilizes the spatial structure extension of the entire equipment to directly introduce the discharge chamber 300 into the glass mixing preparation room, eliminating the process of transferring crushed raw materials using intermediate equipment in the traditional process, further reducing the chance of raw materials contacting air moisture and caking, optimizing the process flow, and saving labor costs.

[0050] In some embodiments of this application, such as Figure 2As shown, the crushing assembly includes a rotary motor 112, a telescopic arm 111, and a crushing punch 101. The rotary motor 112 is positioned above the crushing chamber 100. The lower output end of the rotary motor 112 is connected to the crushing punch 101 via the telescopic arm 111. The crushing punch 101 is located inside the crushing chamber 100 and can crush the raw materials to meet the mixing particle size requirements. A feed inlet 102 is provided on the side wall of the crushing chamber 100. Under the extension and retraction of the telescopic arm 111, the highest position of the crushing punch 101 is higher than the position height of the feed inlet 102. In a preferred embodiment of this application, an arc-shaped push-pull baffle is provided at the feed inlet 102 to ensure sealing at the feed inlet 102.

[0051] In existing conventional crushers, such as hammer crushers, the crushing mechanism is fixed inside the crusher. Crushing requires first activating the crushing mechanism, and then feeding the raw material into the crusher. However, this structure is prone to problems. On the one hand, the crusher's motor may stall due to excessively rapid material accumulation or the crushing mechanism not being fully operational, potentially even burning out the motor. On the other hand, dust and particles can easily escape during the feeding process, threatening worker health and even personal safety.

[0052] In this application, the crushing punch 101 is installed inside the crushing chamber 100 using a telescopic arm 111 for hoisting. During operation, the feed inlet 102 is first opened, and raw materials are added to the crushing chamber 100 through the feed inlet 102. Simultaneously or subsequently, the rotary motor 112 is started to make the crushing punch 101 begin to operate. At this time, the telescopic arm 111 is retracted to its shortest position, and the position of the crushing punch 101 is higher than the position of the feed inlet 102 without interfering with the feeding. Moreover, since no crushing occurs during the raw material addition process, no dust or particles escape, eliminating the risk of dust pollution. After feeding is complete and the crushing punch 101 has been fully operational, the telescopic arm 111 gradually descends to the area where the raw material is located, allowing the crushing punch 101 to crush the raw material. This structure effectively avoids motor stalling, preventing equipment blockage and motor burnout, while also reducing the probability of dust pollution, which is beneficial to the health and safety of workers. In addition, if a malfunction or blockage occurs, the telescopic arm 111 can be used to quickly lift the crushing punch 101 to remove it from the raw material for troubleshooting. This eliminates the need for manual cleaning of the raw material to expose the crushing punch 101, making troubleshooting more convenient and safer, and saving manpower.

[0053] In some preferred embodiments of this application, the telescopic arm 111 adopts a hydraulic structure, which provides precise and stable telescopic control to avoid unnecessary swaying.

[0054] In some embodiments of this application, such as Figure 2 and Figure 3As shown, to further prevent motor stalling and equipment blockage during the crushing process, the crushing punch 101 is a cone shape with its tip pointing downwards. The cone-shaped side of the crushing punch 101 is equipped with a multi-layered crushing hammer structure 1011. When the crushing punch 101 rotates at high speed, the raw material is repeatedly crushed by collision between the crushing hammer structure 1011 and the wall of the crushing chamber 100 to achieve the desired particle size. The cone-shaped tip of the crushing punch 101 is designated as a hammerless zone 1012. When the crushing punch 101 descends to contact the raw material, the hammerless zone 1012 reduces the resistance at the moment of contact and drives the surrounding raw material to rotate through friction. This provides an initial velocity for the crushing hammer structure 1011 to contact the raw material, further reducing resistance and preventing the possibility of motor stalling.

[0055] Preferably, the hydraulic breaker structures 1011 are evenly distributed from bottom to top, and the vertical length covered by the hammerless zone 1012 is not less than the vertical length occupied by the two layers of hydraulic breaker structures 1011. This vertical length ensures sufficient resistance buffer time during the contact process, preventing the rotary motor 112 from stalling or overheating. The width of the upper end face of the hammerless zone 1012 is smaller than the width of the bottommost hydraulic breaker structure 1011, thus not affecting the breaking intervention of the hydraulic breaker structure 1011.

[0056] refer to Figure 3 As shown in the preferred embodiment of this application, the front end face of the hydraulic breaker structure 1011 is a planar structure perpendicular to the rotation tangent, and the front end face is distributed with breaking spikes; the rear end of the hydraulic breaker structure 1011 is an arc-shaped pointed angle structure formed by an arc and a chord, and the angle range of the arc-shaped pointed angle is 25°≤α≤35°; the outer surface of the hydraulic breaker structure 1011 is an outwardly convex arc surface. The hydraulic breaker structure 1011 with the above-described shape design can quickly and thoroughly break raw materials, with less resistance and higher efficiency.

[0057] In some embodiments of this application, the crushing assembly further includes a lifting cantilever 113, which is rotatable above the crushing chamber 100. A rotary motor 112, a telescopic arm 111, and a crushing punch 101 are mounted on the lifting cantilever 113. The lifting cantilever 113 provides a foundation structure for lifting the crushing punch 101 and facilitates the disassembly, assembly, and maintenance of the crushing punch 101 by rotating it to or away from the crushing chamber 100. Figure 2 As shown, the rotating structure of the lifting cantilever 113 includes a rotating shaft 114, a drive motor 115, and a drive box 116. When maintenance is required, the lifting cantilever 113 rotates around the rotating shaft 114 under the drive of the drive motor 115 and the drive box 116, thereby rotating the crushing component away from the top of the crushing chamber 100 and moving the crushing punch 101 out of the crushing chamber 100 for convenient maintenance operations.

[0058] In some embodiments of this application, such as Figure 4As shown, a cover plate 110 is provided at the upper end of the crushing chamber 100. The cover plate 110 is provided with a telescopic hole, through which a telescopic arm 111 passes to place the crushing punch 101 into the crushing chamber 100. A sealing gasket is provided between the telescopic hole and the telescopic arm 111 to meet the sealing requirements of the crushing chamber 100. In some preferred embodiments of this application, the cover plate 110 is provided with a lifting handle. During maintenance, the cover plate 110 can be suspended from the lifting arm 113 via the lifting handle and rotated out of the crushing chamber 100 together with the crushing punch 101 by the lifting arm 113, thus eliminating the need to remove it for each maintenance and simplifying the maintenance process.

[0059] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the crushing chamber 100 includes a discharge port located at the bottom. Above the discharge port, a screen 106 and a first gate 105 are arranged. The screen 106 is a pull-out structure, located below the crushing assembly, used to screen raw materials to ensure that the raw materials meet the particle size requirements. Due to its pull-out design, the screen 106 can be pulled out and removed from the outside of the crushing chamber 100, making maintenance and cleaning convenient. The first gate 105 is a pneumatic gate, located below the screen 106. The first gate 105 is driven by a first cylinder 104 and a connecting rod transmission structure, such as... Figure 6 As shown in the enlarged view, the inner wall of the crushing chamber 100 is provided with a groove 109 that engages with the first gate 105 to stabilize the position of the first gate 105. The first gate 105 is used to control the opening and closing of the discharge function of the crushing chamber 100. In addition, the lower side wall of the crushing chamber 100 is also provided with a discharge port 108, which is used to open after crushing to clean the chamber and remove residual raw materials.

[0060] In some embodiments of this application, the crushing chamber 100 is further provided with an inert gas input pipe, which can pass into the crushing chamber 100 from the top cover plate 110. A control valve is provided on the inert gas input pipe. Before crushing begins, the control valve can be opened to introduce inert gas into the equipment to expel air and reduce moisture content. In a more preferred embodiment of this application, in conjunction with the inert gas input pipe, the crushing chamber 100 is also provided with a drying device. The drying device is also located at the cover plate 110, adjacent to the inert gas input pipe, and can dry the introduced inert gas. Through the dried inert gas, the crushing chamber 100, the first screw feeder 400, the weighing chamber 200, the second screw feeder 500, and the discharge chamber 300 are dried from top to bottom. By installing the inert gas input pipe and the drying device at the cover plate 110, the impact on the high-speed operating crushing punch 101 can be avoided.

[0061] In some embodiments of this application, such as Figure 7As shown, the weighing component of the weighing chamber 200 is a can-type weight sensor 207, which can accurately weigh the crushed raw materials to achieve quantitative crushing and transportation of the raw materials. It is also robust and durable, suitable for harsh environments. The can-type weight sensor 207 is installed on the lower side wall of the weighing chamber 200 to weigh the raw materials inside the weighing chamber 200.

[0062] In some embodiments of this application, such as Figure 7 As shown, a second gate 201 is provided at the upper feed end of the weighing bin 200, and a third gate 206 is provided at the lower discharge end of the weighing bin 200. Both the second gate 201 and the third gate 206 are pneumatic gates. The second gate 201 is driven by a second cylinder 202 and a connecting rod transmission structure, and the third gate 206 is driven by a third cylinder 205 and a connecting rod transmission structure. During operation, the second gate 201 opens when the first screw feeder 400 is turned on to allow material to enter the weighing bin 200. When the raw material in the weighing bin 200 reaches the set value, the first screw feeder 400 can be stopped. After the first screw feeder 400 is completely turned off, the second gate 201 closes. At this time, since there may still be raw material that has not fallen, the third gate 206 opens to release material after the second gate 201 has been closed for a preset time to ensure that all raw material has fallen and to ensure accurate weighing of raw material.

[0063] In some embodiments of this application, to facilitate the falling of raw materials, the crushing chamber 100, weighing chamber 200, and discharge chamber 300 are all cylindrical conical bottom structures, and the outer walls of the crushing chamber 100, weighing chamber 200, and discharge chamber 300 are all equipped with wall vibrators and air hammers. (Reference) Figures 5 to 8 As shown, the outer wall of the crushing chamber 100 is equipped with a first wall vibrator 107 and a first air hammer 103, the outer wall of the weighing chamber 200 is equipped with a second wall vibrator 203 and a second air hammer 204, and the side wall of the discharge chamber 300 is equipped with a third wall vibrator 303 and a third air hammer 304. The wall vibrators are located on the cylindrical section of the chamber, while the air hammers, having greater vibration capability, are located on the conical bottom side of the chamber, thereby maximizing material descent and meeting vibration requirements such as those for cleaning.

[0064] In some embodiments of this application, such as Figure 8 As shown, a fourth gate 301 is provided at the upper feed end of the discharge bin 300. The fourth gate 301 is also a pneumatic gate, driven by a fourth cylinder 302 and a connecting rod transmission structure. The fourth gate 301 opens when the second screw feeder 500 is turned on, so that the discharge bin 300 can be fed. A ball valve and a ball valve switch 305 are provided at the lower discharge end of the discharge bin 300.

[0065] In some embodiments of this application, such as Figure 8As shown, a container receiving plate 306 is also provided at the lower discharge end of the discharge bin 300. The container receiving plate 306 is a cover-type structure with the opening facing downward, which is used to cover the pre-set receiving container to reduce the dust impact during the discharge process.

[0066] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, flexible connection structures are provided between the upper feed end of the weighing bin 200 and the first screw feeder 400, as well as between the discharge bin 300 and the second screw feeder 500. These flexible connection structures are the first flexible connection structure 208 and the second flexible connection structure 307. Through these flexible connection structures, a sealed connection space can be easily formed at the lower outlet of the screw feeder. On the other hand, the vibration of the screw feeder can be prevented from being transmitted to the weighing bin 200 and the discharge bin 300, thus affecting the accuracy of weighing and quantitative conveying of raw materials.

[0067] The following is an overall description of the working process of the crushing equipment in the embodiments of this application:

[0068] First, open the feed inlet 102 of the crushing chamber 100 and pour the raw material into the crushing chamber 100. At the same time or afterward, turn on the rotary motor 112 to start the crushing punch 101. At this time, the telescopic arm 111 is retracted to its shortest position, and the position of the crushing punch 101 is higher than the position of the feed inlet 102 without interfering with the feeding.

[0069] After feeding is complete and the crushing punch 101 is fully operational, the telescopic arm 111 is controlled to gradually descend to the area where the raw material is located, allowing the crushing punch 101 to crush the raw material. The raw material is repeatedly crushed by collisions between the crushing punch 101 and the bin wall. The raw material that meets the particle size requirements will pass through the screen 106 and enter the first screw feeder 400. At the same time, the first wall vibrator 107 of the crushing bin 100 will start operating to accelerate the flow of the raw material.

[0070] The first screw feeder 400 transports the qualified raw materials to the weighing bin 200. At this time, the weighing bin 200 starts to calculate the weight. When the weight reaches the set value (the set value should usually be the weight of a single piece of raw material, and the remaining amount in the weighing bin should be added for the first use of the day), the first gate 105 of the crushing bin 100 will close. After the first screw feeder 400 is emptied (usually 10-30 seconds), the motor of the first screw feeder 400 also stops, and the second gate 201 of the weighing bin 200 closes, stopping the feeding of the weighing bin 200. At this time, the telescopic arm 111 in the crushing bin 100 will raise the crushing punch 101 to an area that does not contact the raw material, that is, the area above the feed inlet 102. The rotary motor 112 stops rotating and waits for the next crushing command.

[0071] Meanwhile, the third gate 206 of the weighing bin 200 will open after the second gate 201 has been closed for a preset time. Next, the weighing bin 200 will discharge material downwards according to the set weight of the raw material. The second screw feeder 500 below the weighing bin 200 will start operating, and the second wall vibrator 203 of the weighing bin 200 will also start operating. When the initial weight of the raw material in the weighing bin 200 minus the remaining amount equals the required quantity of raw material, the third gate 206 of the weighing bin 200 will close promptly, and the second wall vibrator 203 will stop operating. After all the raw material in the second screw feeder 500 has been transported to the discharge bin 300, the second screw feeder 500 will also stop operating.

[0072] Then, the discharge hopper 300 can be opened to discharge materials as needed for quantitative preparation of glass mixtures.

[0073] Repeat the above steps until the required raw materials for the day are prepared, or until all the required raw materials for the day are prepared, then the inventory clearance operation can begin.

[0074] After the cleaning begins, the wall vibrators and air hammers of the crushing bin 100, weighing bin 200 and discharge bin 300 will all be activated, the gates will be opened, and the first screw feeder 400 and the second screw feeder 500 will also be activated at the same time to automatically empty the remaining raw materials in each bin and the screw feeders. This process lasts for about 3 minutes. After the automatic cleaning is completed, a receiving container is placed at the discharge end of the discharge bin 300, and the ball valve switch 305 is opened to load the remaining raw materials in the bin into the receiving container.

[0075] Finally, after the automatic emptying process is completed, open the material outlet 108 of the crushing chamber 100 to remove any remaining uncrushed lumpy raw materials from the crushing chamber 100 and store them together with the automatically emptied raw materials.

[0076] According to another aspect of this application, a method for crushing moisture-absorbing glass raw materials is also disclosed, applicable to the crushing equipment for moisture-absorbing glass raw materials in the above embodiments, such as... Figure 9 As shown, the method includes:

[0077] Step S910: Add glass raw material into the crushing chamber 100, turn on the crushing component and gradually bring the crushing component into contact with the glass raw material to crush it.

[0078] Specifically, in step S910, after the feeding is completed and the crushing punch 101 is fully operational, the telescopic arm 111 is controlled to gradually descend to the area where the raw material is located, so that the crushing punch 101 crushes the raw material.

[0079] In step S920, after the crushing component starts crushing, the first screw feeder 400 is turned on to send the glass raw material with the required particle size after crushing to the weighing bin 200.

[0080] In step S930, keep the discharge end of the weighing bin 200 closed. After the weighing bin 200 has weighed the set weight of glass raw material, close the first screw feeder 400 and the feed end of the weighing bin 200, and open the discharge end of the weighing bin 200.

[0081] Specifically, in step S930, after the weighing chamber 200 weighs the set weight of glass raw material, the telescopic arm 111 in the crushing chamber 100 is controlled to raise the crushing punch 101 to an area that does not contact the raw material, that is, the area above the feed inlet 102, and at the same time the rotating motor 112 is stopped, waiting for the next crushing command.

[0082] In addition, in step S930, after the weighing chamber 200 weighs the set weight of glass raw material, the discharge end of the crushing chamber 100, i.e., the first gate 105, is closed first. After the first screw feeder 400 is emptied (generally 10-30s), the first screw feeder 400 is stopped and the feed end of the weighing chamber 200, i.e., the second gate 201, is closed. After the feed end of the weighing chamber 200 is closed for a preset time, the discharge end of the weighing chamber 200, i.e., the third gate 206, is opened.

[0083] Step S940: Start the second screw feeder 500 and transport a fixed amount of glass raw material to the discharge bin 300 according to the weight weighed in the weighing bin 200.

[0084] Step S950: Open the discharge hopper 300 to discharge a fixed amount of glass raw material into the glass mixing and preparation room.

[0085] In summary, through the embodiments of this application, the crushing chamber 100, weighing chamber 200, discharge chamber 300, first screw feeder 400, and second screw feeder 500 form a sealed equipment unit, which can complete the crushing, weighing, and quantitative transportation of raw materials in one go. The entire processing is carried out within the sealed equipment unit, which on the one hand avoids the raw materials absorbing air moisture and re-caking, ensuring accurate weighing and use of raw materials, and on the other hand limits the dust problem during the raw material crushing process, improving the working environment for workers. Moreover, the embodiments of this application utilize the spatial structure of the entire equipment to extend the discharge chamber 300 directly into the glass mixing preparation room, eliminating the process of transferring crushed raw materials using intermediate equipment in traditional processes, further reducing the chance of raw materials contacting air moisture and caking, optimizing the process flow, and saving labor costs.

[0086] In a preferred embodiment of this application, the crushing punch 101 is hoisted and installed by a telescopic arm 111, and the crushing punch 101 is a cone shape with the tip pointing downwards. The cone side of the crushing punch 101 is provided with a multi-layer breaker hammer structure 1011, and the cone tip of the crushing punch 101 is set as a hammerless area 1012. The lifting design can prevent the motor from stalling and reduce the occurrence of equipment blockage. At the same time, with the help of the rotatable hoisting arm 113, the crushing component can be rotated away from the crushing chamber 100, thereby making installation and maintenance more convenient.

[0087] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
