Description

Technical Field

[0001] The present invention relates to the technical field of rock wool board crushing, and specifically to a crushing device for rock wool boards with a dust prevention function. Background Art

[0002] Rock wool boards can be recycled. However, due to the relatively low density of rock wool, the transportation cost is high. Waste rock wool can still be recycled in large quantities. Since these waste materials are difficult to degrade and pollute the environment, most of them are dumped and buried. The amount of such waste residue and waste materials is at least several thousand tons and at most tens of thousands of tons per year. Dumping and burying not only waste manpower and transportation capacity, but also face great environmental protection pressure. If centralized recycling can reduce the recycling cost, crushing the rock wool board can effectively improve production efficiency;

[0003] However, when general crushing equipment crushes rock wool boards, a small amount of dust will escape everywhere. At the same time, the existing crushing equipment cannot automatically change the crushing size of the rock wool board during crushing. Therefore, even when recycling the rock wool board debris later, due to the different sizes of the debris, the recycling efficiency will decrease. And because the crushing equipment uses a motor with strong power and high consumption for efficient crushing, it will cause smoke and dust to overflow, the machine to shake violently and consume a lot. Summary of the Invention

[0004] The purpose of the present invention is to provide a crushing device for rock wool boards with a dust prevention function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A crushing device for rock wool boards with a dust prevention function, including a crushing device main body and a controller. The crushing device main body includes a crushing chamber. An anti-dust component is installed above the crushing chamber. A crushing component is arranged at the bottom of the anti-dust component. A diversion component is arranged at the bottom of the crushing component. A pulverizing component is arranged at the bottom of the diversion component. A conveyor belt is arranged at the output end of the pulverizing component.

[0006] Further, the anti-dust component includes an arc-shaped cover and a roller. The roller is driven by a motor drive rod. The arc-shaped cover and the roller are respectively installed inside the crushing chamber. The arc-shaped cover is installed above the roller. Both ends of the roller are respectively installed inside the crushing chamber through bearings. The roller is provided with holes. A support rod is arranged inside the roller. A plurality of baffle pieces are arranged outside the support rod. A plurality of connecting sleeves are arranged between the baffle pieces and the support rod. A spring is arranged inside the connecting sleeve. One end of the connecting sleeve is connected to the support rod. The spring passes through the other end of the connecting sleeve and is connected to the baffle plate. Both the arc-shaped cover and the baffle plate have magnetism, and the arc-shaped cover and the baffle plate attract each other.

[0007] Further, the crushing assembly includes a main crushing rod, two mounting sleeves and two secondary crushing rods. The main crushing rod is located between the two secondary crushing rods. The main crushing rod includes two crushing pieces, both of which are semi-circular. The two crushing pieces can form a complete cylindrical main crushing rod. An electromagnet is embedded on the smooth side of the two crushing pieces. The two ends of the secondary crushing rods are installed inside the crushing chamber through bearings. The two mounting sleeves are respectively installed at the two ends of the main crushing rod. Multiple limiting rods are connected between the mounting sleeves and the two crushing pieces.

[0008] Further, when the electromagnet is energized: the two crushing pieces will combine into a complete main crushing rod;

[0009] At this time, the gap between the main crushing rod and the secondary crushing rods will be reduced;

[0010] When the electromagnet is de-energized: the main crushing rod will separate into two crushing pieces;

[0011] At this time, the distance between the main crushing rod and the secondary crushing rods will be restored.

[0012] Further, the diversion assembly includes a diversion pipe. The diversion pipe is installed at the bottom of the crushing assembly. The diameter of the feed inlet of the diversion pipe is larger than that of the discharge port. An installation frame is installed outside the diversion pipe. Multiple blowing assemblies are installed between the installation frames. The blowing assemblies are equidistantly installed on the installation frames. The blowing assemblies can divert fine rock wool board debris.

[0013] Further, the blowing assembly includes a blade and two copper pipes. The two copper pipes are installed below the blade. The output direction of the blade is between the two copper pipes. The blade is connected with a positive current, and the two copper pipes are connected with a negative current.

[0014] Further, the crushing and grinding assembly includes a crushing and grinding tank. A partition board, a support platform and a discharge port are arranged at the bottom of the crushing and grinding tank. The partition board is located above the support platform, and the discharge port is located above the partition board. A crushing and grinding motor is arranged at the bottom of the support platform. A driving gear and multiple driven gears are installed above the support platform. The driven gears are connected with the support platform through bearings. The driving gear and the driven gears cooperate with each other. A turntable and multiple secondary crushing and grinding rods are installed above the partition board. Each secondary crushing and grinding rod is respectively connected with the driven gear through a connecting rod. The turntable is connected with the driving gear through a connecting rod.

[0015] Further, multiple main crushing and grinding rods are installed above the turntable. Multiple bearings are respectively arranged on the main crushing and grinding rods and the secondary crushing and grinding rods. Multiple crushing and grinding pieces are installed on each bearing. A counterweight block is arranged at the other end of the crushing and grinding piece.

[0016] Furthermore, the powder fragments on two adjacent groups of the main crushing rods do not interfere with each other, and the powder fragments on two adjacent groups of the secondary crushing rods also do not interfere with each other. The powder fragments on the main crushing rods can collide with the powder fragments on the secondary crushing rods.

[0017] Furthermore, the controller is arranged outside the crushing bin. The upper surface of the controller is provided with an operation panel, and the operation panel can control the main body of the crushing device.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. Thus, when the device is in use, it can reduce the dust generated by the rock wool board during crushing. At the same time, the crushing assembly can also be adjusted according to requirements, so as to adapt to rock wool boards of different sizes. After that, the crushed materials will be guided by the diversion assembly and discharged to the crushing assembly, and then the crushing assembly will unify the size of the rock wool board debris again, so as to facilitate the subsequent recycling process;

[0020] 2. When the dust prevention and suppression assembly of the device is in use, it can block the debris and reduce the dust generated by crushing at the same time. When the roller rotates, the baffle inside the roller will also rotate. When the baffle moves to the side close to the arc-shaped cover, the baffle will attract the arc-shaped cover, so as to prevent the holes from being blocked, and thus prevent some liquid from being discharged from the gas holes. When the external motor drives the roller to rotate rapidly, the baffle will block the holes by itself under the drive of inertia, so as to limit the drainage volume of the liquid;

[0021] 3. The crushing assembly of the device can crush the crushed materials. When the crushing assembly is specifically in use, the crushing assembly is also driven by an external motor. When the main crushing rod and the two secondary crushing rods rotate, the materials passing through the three will be crushed. When the main crushing rod is specifically in use, when the electromagnets are powered on, the two electromagnets will attract each other. At this time, the main crushing rod will remain unchanged and continue to crush the materials in a cylindrical state. When the power supply to the electromagnets is stopped, the main crushing rod will be separated into two semi-circular crushing pieces, and at the same time, the distance between the main crushing rod and the secondary crushing rods will be reduced, so as to crush smaller-sized crushed materials. Therefore, when the crushing assembly is in use, it can change the distance between the main crushing rod and the secondary crushing rods according to the different crushed materials, so as to achieve a more comprehensive crushing work. And when the device is in use, because the motor is an energy-saving engine, it can save a certain amount of resource consumption;

[0022] 4. When the blowing component of the device is in use, it can divert fine debris to prevent the fine debris from flowing out through the gap between the diversion component and the crushing component. During specific use, since a positive current is connected to the blade and a negative current is connected to two groups, the voltage breaks down the air to form charged ions, and the charged ions move from the strong pole to the weak pole, thereby forming an ionic wind, which can divert the debris generated by the crushing component and prevent the debris from spreading everywhere.

[0023] 5. When the crushing component is in use, it can crush the preliminarily broken materials to unify the size of the final debris. Brief Description of the Drawings

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment: As Figures 1-8 shown, the present invention provides a technical solution for a crushing device for rock wool boards with a dust prevention function, including a crushing device main body 1 and a controller 7. The crushing device main body 1 includes a crushing bin 11. An anti-dust component 2 is installed above the crushing bin 11. A crushing component 3 is arranged at the bottom of the anti-dust component 2. A diversion component 4 is arranged at the bottom of the crushing component 3. A pulverizing component 5 is arranged at the bottom of the diversion component 4. A conveyor belt is arranged at the output end of the pulverizing component 5;

[0035] Thus, when the device is in use, after the crushed material is placed into the crushing bin 11, the crushing component 3 can crush the crushed material. When the crushing component 3 crushes the crushed material, the anti-dust component 2 can block the debris and at the same time reduce the dust generated by crushing. The crushed debris after crushing will be discharged into the pulverizing component 5 under the guidance of the diversion component 4. Then, the pulverizing component 5 thoroughly pulverizes the crushed debris after crushing. The crushed debris after pulverization will be discharged through the output end of the pulverizing component 5 and conveyed by the conveyor belt. In specific use, the crushing component 3 can automatically adjust the distance between the main crushing rod 31 and the secondary crushing rod 32 according to the size of the crushed material, so as to fully crush the crushed material, adapt to crushed materials of different sizes, and at the same time adjust the size of the crushed material after crushing. The material after primary crushing will be discharged into the pulverizing component 5 under the guidance of the diversion component 4. The larger crushed materials will be introduced into the pulverizing component 5 along the diversion pipe 41. At the same time, the external blowing component 6 can guide the fine debris to prevent the fine debris from floating around wantonly. Then, the pulverizing component 5 can pulverize the preliminarily crushed material. When the pulverizing component 5 pulverizes the crushed material, it can impact the crushed material multiple times, so as to pulverize the crushed material more evenly. Thus, when the device is in use, it can accurately pulverize the crushed material for subsequent reuse. And when the device is in use, because the motor is an energy-saving engine, a certain amount of resource consumption can be saved.

[0036] As Figures 2-3As shown, in this embodiment, specifically, the dust prevention and suppression component 2 includes an arc-shaped cover 21 and a roller 22. The roller 22 is driven by a motor drive rod. The arc-shaped cover 21 and the roller 22 are respectively installed inside the crushing chamber 11. The arc-shaped cover 21 is installed above the roller 22. Both ends of the roller 22 are installed inside the crushing chamber 11 through bearings. The roller 22 is provided with holes. Inside the roller 22, there is a support rod 23. Outside the support rod 23, there are multiple groups of baffle plates. Between the baffle plates and the support rod 23, there are multiple groups of connecting sleeves 24. Inside the connecting sleeve 24, there is a spring. One end of the connecting sleeve 24 is connected to the support rod 23, and the spring passes through the other end of the connecting sleeve 24 and is connected to the baffle plate. Both the arc-shaped cover 21 and the baffle plate have magnetism, and the arc-shaped cover 21 and the baffle plate attract each other;

[0037] When the dust prevention and suppression component 2 of this device is in use, it can block debris and at the same time reduce the dust generated by crushing. Specifically in use, an external motor can drive the roller 22 to rotate, and at the same time, liquid is continuously injected into the roller 22. At this time, when crushing the crushed material, the external motor will also drive the roller 22 to rotate slowly, and the liquid will be discharged through the holes, thereby reducing the dust of the crushed material during crushing. When the roller 22 rotates, the baffle plate inside the roller 22 will also rotate. When the baffle plate moves to the side close to the arc-shaped cover 21, the baffle plate will attract the arc-shaped cover 21, thereby preventing the holes from being blocked and preventing some of the liquid from being discharged through the gas holes. When the external motor drives the roller 22 to rotate quickly, the baffle plate will, under the drive of inertia, automatically block the holes, thus limiting the drainage of the liquid.

[0038] As Figure 2 shown, in this embodiment, specifically, the crushing component 3 includes a main crushing rod 31, two installation sleeves 33, and two secondary crushing rods 32. The main crushing rod 31 is located between the two secondary crushing rods 32. The main crushing rod 31 includes two crushing pieces. Both of the two crushing pieces are semi-circular. The two crushing pieces can form a complete cylindrical main crushing rod 31. Inside the smooth surface of the two crushing pieces, there are embedded electromagnets 311. Both ends of the secondary crushing rod 32 are installed inside the crushing chamber 11 through bearings. The two installation sleeves 33 are respectively installed at both ends of the main crushing rod 31. Between the installation sleeves 33, there are multiple groups of limiting rods connecting the two crushing pieces;

[0039] The crushing component 3 of the device can crush the shredded materials. When the crushing component 3 is specifically used, the crushing component 3 is also driven by an external motor. When the main crushing rod 31 and the two sets of secondary crushing rods 32 are rotating, the materials passing between the three will be crushed. When the main crushing rod 31 is specifically used, when the electromagnets 311 are powered, the two sets of electromagnets 311 will attract each other. At this time, the main crushing rod 31 will remain held together and continue to crush the materials in a cylindrical state. When the power supply to the electromagnets 311 is stopped, the main crushing rod 31 will be separated into two semi-circular crushing pieces. At the same time, the distance between the main crushing rod 31 and the secondary crushing rods 32 will be reduced, so as to be able to crush shredded materials with a smaller volume. Therefore, when the crushing component 3 is used, it can change the distance between the main crushing rod 31 and the secondary crushing rods 32 according to the different shredded materials, so as to achieve a more comprehensive crushing operation.

[0040] As Figure 2 shown, in this embodiment, specifically, when the electromagnets 311 are energized: the two crushing pieces will combine into a complete main crushing rod 31;

[0041] At this time, the gap between the main crushing rod 31 and the secondary crushing rods 32 will be reduced;

[0042] When the electromagnets 311 are de-energized: the main crushing rod 31 will be separated into two sets of crushing pieces;

[0043] At this time, the distance between the main crushing rod 31 and the secondary crushing rods 32 will be restored;

[0044] When the electromagnets 311 are powered, the two sets of electromagnets 311 will attract each other. At this time, the main crushing rod 31 will remain held together and continue to crush the materials in a cylindrical state. When the power supply to the electromagnets 311 is stopped, the main crushing rod 31 will be separated into two semi-circular crushing pieces. At the same time, the distance between the main crushing rod 31 and the secondary crushing rods 32 will be reduced, so as to be able to crush shredded materials with a smaller volume.

[0045] As Figure 2 and Figure 5 shown, in this embodiment, specifically, the diversion component 4 includes a diversion pipe 41. The diversion pipe 41 is installed at the bottom of the crushing component 3. The diameter of the feed inlet of the diversion pipe 41 is larger than the diameter of the discharge port. An installation frame is installed outside the diversion pipe 41. Multiple groups of blowing components 6 are installed between the installation frames. The blowing components 6 are equidistantly installed on the installation frames. The blowing components 6 can divert fine rock wool board debris;

[0046] When the diversion component 4 of the device is in use, it can divert the crushed materials and at the same time drain the powdery debris. When the diversion component 4 is specifically in use, the materials after crushing will directly fall into the crushing component 5 along the diversion pipe 41. In order to facilitate the maintenance of the crushing component 5, a certain gap is provided between the crushing component 5 and the diversion component 4, which will cause some debris to be discharged through the gap. Through the blowing component 6 of the device, the overflowing debris can be blown back into the crushing component 5, and then the crushed materials and debris are discharged uniformly.

[0047] As Figure 7 shown, in this embodiment, specifically, the blowing component 6 includes a blade 61 and two groups of copper tubes 62. The two groups of copper tubes 62 are installed below the blade 61. The output direction of the blade 61 is between the two groups of copper tubes 62. The blade 61 is connected to a positive current, and the two groups of copper tubes 62 are connected to a negative current;

[0048] When the blowing component 6 of the device is in use, it can drain the fine debris and prevent the fine debris from flowing out through the gap between the diversion component 4 and the crushing component 5. When specifically in use, because a positive current is connected to the blade 61 and a negative current is connected to the two groups of copper tubes, the voltage breaks down the air to form charged ions, and the charged ions move from the strong pole to the weak pole, thereby forming an ionic wind, which can divert the debris generated by the crushing component 3 and prevent the debris from spreading everywhere.

[0049] As Figure 2 、 Figures 5-8 shown, in this embodiment, specifically, the crushing component 5 includes a crushing tank 51. A partition 52, a support platform 53 and a discharge port are provided at the bottom of the crushing tank 51. The partition 52 is located above the support platform 53, the discharge port is located above the partition 52, a crushing motor 54 is provided at the bottom of the support platform 53, a driving gear 55 and multiple groups of driven gears 56 are installed above the support platform 53. The driven gears 56 are connected to the support platform 53 through bearings. The driving gear 55 and the driven gears 56 cooperate with each other. A turntable and multiple groups of secondary crushing rods 57 are installed above the partition 52. Each group of secondary crushing rods 57 is respectively connected to the driven gear 56 through a connecting rod. The turntable is connected to the driving gear 55 through a connecting rod;

[0050] When the crushing component 5 is in use, it can crush the shredded materials after preliminary crushing to unify the size of the final debris. Specifically, when in use, the crushing motor 54 can drive the driving gear 55 to rotate. Since the driving gear 55 meshes with the driven gear 56, the driven gear 56 can be driven to rotate. When both the driving gear 55 and the driven gear 56 rotate, the secondary crushing rod 57 and the turntable will be driven to rotate together. When the secondary crushing rod 57 rotates, it can cooperate with the structure on the turntable to crush the shredded materials together, making the finally discharged shredded materials finer.

[0051] As Figure 5 shown, in this embodiment, specifically, multiple groups of primary crushing rods 58 are installed above the turntable. Multiple groups of bearings are respectively arranged on the primary crushing rods 58 and the secondary crushing rods 57. Multiple groups of crushing pieces 59 are installed on each group of bearings. A counterweight is arranged at the other end of the crushing piece 59;

[0052] Since multiple groups of crushing pieces are installed on the primary crushing rods 58 and the secondary crushing rods 57 through bearings, when the primary crushing rods 58 and the secondary crushing rods 57 rotate, the crushing pieces 59 thereon will rotate with inertia during the rotation process, and the counterweight will increase this inertia. Therefore, the shredded materials can be thoroughly crushed by multiple groups of crushing pieces 59.

[0053] As Figure 5 shown, in this embodiment, specifically, the crushing pieces 59 on two adjacent primary crushing rods 58 do not interfere with each other, and the crushing pieces 59 on two adjacent secondary crushing rods 57 also do not interfere with each other. The crushing pieces 59 on the primary crushing rods 58 can collide with the crushing pieces 59 on the secondary crushing rods 57;

[0054] Furthermore, when the primary crushing rods 58 rotate, the crushing pieces 59 on the primary crushing rods 58 will not collide with each other. Since the distance between the primary crushing rods 58 is small, when one group of crushing pieces 59 collides, it is easy to affect other crushing pieces 59. At this time, a certain gap will be generated between the crushing pieces 59, resulting in a reduction in the crushing effect and an inability to thoroughly crush larger materials. Similarly, after the crushing pieces 59 on the secondary crushing rods 57 collide, a certain gap will also be generated between two adjacent secondary crushing rods 57, resulting in incomplete crushing. However, the crushing pieces 59 on the primary crushing rods 58 can collide with the crushing pieces 59 on the secondary crushing rods 57, and at this time, no gap will be generated. Because after the two collide, the debris between the two groups of crushing pieces 59 will receive a greater force, and at the same time, the crushing pieces 59 will rotate in the opposite direction, thus breaking away from the revolution and achieving self-rotation. Therefore, multiple groups of crushing pieces 59 rotate in different directions, which can crush the debris more thoroughly during crushing.

[0055] As Figure 1As shown in the figure, in this embodiment, specifically, a controller 7 is disposed outside the crushing bin 11. A control panel is provided on the upper surface of the controller 7, and the control panel can control the main body 1 of the crushing device;

[0056] Therefore, when the device is in use, each component of the main body 1 of the crushing device can be controlled through the controller 7. Since a control panel is provided on the controller 7, the staff can control the main body 1 of the crushing device through the control panel, so that the main body 1 of the crushing device can better crush the materials.

[0057] Working principle: Therefore, when the device is in use, after the broken materials are placed into the crushing bin 11, the crushing component 3 can crush the broken materials. When the crushing component 3 crushes the broken materials, the anti-dust component 2 can block the debris and at the same time reduce the dust generated by crushing. The crushed debris after crushing will be discharged into the pulverizing component 5 under the guidance of the diversion component 4. Then, the pulverizing component 5 thoroughly pulverizes the crushed debris after crushing. The crushed debris after pulverization will be discharged through the output end of the pulverizing component 5 and conveyed by the conveyor belt. In specific use, the crushing component 3 can automatically adjust the distance between the main crushing rod 31 and the secondary crushing rod 32 according to the size of the broken materials, so as to fully crush the broken materials, adapt to broken materials of different sizes, and at the same time adjust the size of the broken materials after crushing. The materials after primary crushing will be discharged into the pulverizing component 5 under the guidance of the diversion component 4. The larger broken materials will be introduced into the pulverizing component 5 along the diversion pipe 41. At the same time, the external blowing component 6 can guide the fine debris to prevent the fine debris from spreading wantonly. Then, the pulverizing component 5 can pulverize the preliminarily crushed broken materials. When the pulverizing component 5 pulverizes the broken materials, it can impact the broken materials multiple times, so as to pulverize the broken materials more evenly. Therefore, when the device is in use, it can accurately pulverize the broken materials for subsequent reuse. And when the device is in use, since the motors are all energy-saving engines, a certain amount of resource consumption can be saved while ensuring the power source.

[0058] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
