Description

Technical Field

[0001] The present invention relates to the technical field of recycling of waste materials from rock wool processing, and specifically to a waste material recycling device for rock wool cutting production. Background Art

[0002] Rock wool is a high-quality thermal insulation material that originated in Hawaii, and its production process simulates the natural process of volcanic eruptions. Rock wool uses high-quality basalt, dolomite, etc. as the main raw materials. After being melted at high temperature, it is centrifuged into fibers at high speed by a centrifuge, and a certain amount of binder, dust-proof oil, water-repellent agent, etc. are sprayed in. After being collected by a cotton collecting machine and solidified and cut through the pendulum method process and the three-dimensional method of laying cotton, rock wool products of different specifications and uses are formed. Rock wool cutting is a common process step in building and thermal insulation material installation, which involves cutting materials such as rock wool boards or rock wool pipe shells according to specific sizes and shapes to meet the construction requirements.

[0003] The utility model with the publication number CN208880814U discloses a building rock wool automatic cutting device with waste edge recycling treatment. While having the function of cutting rock wool, the waste edges can be crushed on the spot through the provided recycling device, which is convenient for recycling and reuse. The structure of this utility model is simple, the concept is ingenious, and it is convenient to promote.

[0004] The above-mentioned rock wool waste recycling measures are only applicable to the relatively large-sized broken block structures during the cutting process. However, due to the physical properties of rock wool, a large amount of powder or debris will inevitably be generated during cutting. The above-mentioned recycling measures are difficult to recycle this part of the waste materials, and the powder or debris generated during the cutting process will seriously pollute the processing environment and damage the physical health of workers at the same time. This part of the waste materials should be focused on recycling, and this part of the waste materials can be directly used without being crushed after collection. Therefore, in view of the above problems, a waste material recycling device for rock wool cutting production is proposed herein. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a waste recycling device for rock wool cutting production. The waste recycling of rock wool processing can work through an external exhaust fan, generate negative pressure at the suction hood, absorb the dust and debris generated during the cutting process and send them into the recycling box. When the dust and debris enter the recycling box, due to the sudden increase in the air passage area resulting in a decrease in flow velocity, most of the dust and debris will fall to the bottom of the recycling box, while the filter baffle is used to block the lighter part. After absorbing for a period of time, the exhaust fan stops working. At this time, the long-stroke hydraulic cylinder works to drive the pressure-feeding and cleaning integrated mechanism to move down, and finally squeezes and gathers the dust and debris accumulated at the bottom of the recycling box through the pressing plate, which is convenient for taking out and transporting. During the above process, the electric cleaning roller will move synchronously and clean the surface of the filter baffle by driving the rotation of the brush layer, avoiding a significant reduction in the air passage area due to excessive waste adhering to the surface of the filter baffle, and solving the technical problems in the prior art that the recycling device is difficult to directly recycle the powder or debris generated during cutting, resulting in serious pollution of the processing environment by the powder or debris generated during cutting and harming the health of workers at the same time.

[0006] The technical solution adopted by the embodiments of the present application to solve its technical problems is:

[0007] A waste recycling device for rock wool cutting production, including a recycling box, which is respectively provided with a front connection port and a rear connection port at its front and rear ends. The front connection port is connected with a suction hood, and the rear connection port is hermetically connected with an external exhaust fan. A filter baffle is installed on the rear end plate of the recycling box and is located in the rear connection port. A long-stroke hydraulic cylinder is installed on the recycling box, and its output shaft is equipped with a pressure-feeding and cleaning integrated mechanism. Among them, the pressure-feeding and cleaning integrated mechanism includes an upper substrate, a pressing plate is connected to the upper substrate through a sliding connection member, an electric cleaning roller is installed at one end of the upper substrate close to the filter baffle, and a brush layer that fits the filter baffle is sleeved outside the electric cleaning roller.

[0008] Through the above structural form, it is possible to generate negative pressure at the suction hood through the work of an external exhaust fan, absorb the dust and debris generated during the cutting process and send them into the recycling box for recycling. After absorbing for a period of time, the exhaust fan stops working. At this time, the long-stroke hydraulic cylinder works to drive the pressure-feeding and cleaning integrated mechanism to move down, and finally squeezes and gathers the dust and debris accumulated at the bottom of the recycling box through the pressing plate, which is convenient for taking out and transporting. And during the above process, the electric cleaning roller will move synchronously and clean the surface of the filter baffle by driving the rotation of the brush layer, avoiding a significant reduction in the air passage area due to excessive waste adhering to the surface of the filter baffle.

[0009] In a possible implementation manner, the bottom plate of the recycling box is an inclined plate sloping towards one side, and a wedge-shaped pressing block is installed on the lower end surface of the pressing plate, and the bottom surface of the wedge-shaped pressing block is parallel to the bottom plate of the recycling box.

[0010] With the above structural form, after the wedge-shaped pressing block squeezes the waste debris into a whole, it is convenient to take out the compressed waste through the inclined plane.

[0011] In a possible implementation manner, a circular through-hole is provided in the center of the upper substrate, and the output shaft end of the long-stroke hydraulic cylinder passes through the circular through-hole and is fixedly connected to the pressing plate.

[0012] With the above structural form, it is possible to directly drive the movement of the pressing plate by the long-stroke hydraulic cylinder, providing a necessary structural basis for the pressing plate to squeeze the debris waste and drive the movement of the upper substrate.

[0013] In a possible implementation manner, the sliding connecting member includes a guide rod and a cylinder seat. Among them, the guide rod is slidably arranged in the upper substrate, and the bottom end is fixedly connected to the pressing plate. The cylinder seat is sleeved outside the guide rod and fixedly connected to the upper substrate. An anti-disengagement end piece is fixedly connected to the top end of the guide rod, and a return spring is sleeved outside the guide rod. The two ends of the return spring respectively abut against the anti-disengagement end piece and the cylinder seat.

[0014] With the above structural form, when there is no external force, the upper substrate will always be in contact with the pressing plate under the thrust of the return spring, that is, it will move synchronously with the output shaft end of the long-stroke hydraulic cylinder to drive the electric cleaning roller to complete the cleaning of the surface of the filter baffle. When the upper substrate is limited, at this time, the long-stroke hydraulic cylinder can still continue to press down the pressing plate to extrude and shape the debris waste.

[0015] In a possible implementation manner, two groups of limiting blocks are fixedly arranged on the inner wall of the recycling box, and side abutting plates are fixedly arranged on both sides of the upper substrate, and the positions of the side abutting plates correspond to those of the limiting blocks one by one.

[0016] With the above structural form, the combined action of the side abutting plate and the limiting block can play a role in limiting the upper substrate, avoiding the situation that the electric cleaning roller continues to move down and collides with the recycling box.

[0017] In a possible implementation manner, a roller cover fixedly connected to the upper substrate is sleeved outside the electric cleaning roller, and the end of the roller cover does not contact the filter baffle.

[0018] With the above structural form, the roller cover can seal the upper space of the electric cleaning roller, avoiding the situation that the electric cleaning roller brings debris dust into the upper space during rotation and cannot be discharged.

[0019] In a possible implementation manner, a closed frame is fixedly arranged on the inner wall of the recycling box, and the lower end surface of the closed frame can be in close contact with both the upper substrate and the roller cover, and a layer of rubber cushion is attached to the lower end surface of the closed frame.

[0020] Through the above-mentioned structural form, when the output shaft of the long-stroke hydraulic cylinder is in the initial stroke, that is, when the exhaust fan works to absorb dust and debris, the closed frame is tightly fitted with the upper base plate and the drum cover, so as to divide the recovery box into two isolated spaces, that is, the lower space is the collection space, and the upper space is the working space, which can effectively prevent dust and debris from entering the upper space and causing difficulties in subsequent cleaning.

[0021] In a possible implementation, a discharge port is provided at the bottom of the recovery box, and a closed cover plate rotatably connected to the recovery box is provided outside the discharge port.

[0022] Through the above-mentioned structural form, the opened discharge port provides the necessary structural basis for taking out the compressed waste, and the closed cover plate can ensure the airtightness of the internal space when the exhaust fan is working.

[0023] In a possible implementation, the absorption hood includes a trapezoidal hood, which is tightly connected to a front connection port via a pipe connected to the rear side, and a cover plate is installed on the front end surface of the trapezoidal hood, on which a plurality of through holes distributed in an array are opened.

[0024] With the above-mentioned structural form, when the exhaust fan is working, negative pressure will be generated in the trapezoidal cover, and the dust and debris will be sucked into the recovery box through the through holes on the cover plate, thereby playing a recovery role.

[0025] In a possible implementation, the filter baffle includes a frame detachably connected to the recovery box, and a filter screen is detachably installed in the frame.

[0026] The above-mentioned structural form can facilitate maintenance personnel to replace the filter screen, so that the filter baffle can always maintain a large air flow area and a waste blocking function.

[0027] In summary, the present invention includes the following beneficial technical effects:

[0028] The rock wool processing waste recycling can work through an external exhaust fan, generate negative pressure at the absorption cover, absorb the dust and debris generated during the cutting process and send them to the recycling box. When the dust and debris enter the recycling box, the flow rate decreases due to the sudden increase in the wind area, so most of the dust and debris will fall to the bottom of the recycling box, and the filter baffle is used to block the lighter part to play a recycling role;

[0029] After absorbing for a period of time, the exhaust fan stops working. At this time, the long-stroke hydraulic cylinder drives the material pressing and cleaning integrated mechanism to move downward, and finally squeezes and gathers the dust and debris accumulated at the bottom of the recovery box through the pressure plate, so that the waste can be stroked as a whole as possible to facilitate removal and transportation. In the above process, the electric cleaning drum will move synchronously and clean the surface of the filter baffle by driving the brush layer to rotate, so as to avoid excessive waste adhering to the surface of the filter baffle and significantly reducing the wind flow area.

Detailed Embodiments

[0039] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0040] As Figure 1 - Figure 2As shown in the figure, a waste recycling device for rock wool cutting production includes a recycling box 1, with a front connection port 21 and a rear connection port 22 provided at its front and rear ends respectively. An absorption hood 3 is connected to the front connection port 21, and the rear connection port 22 is hermetically connected to an external exhaust fan. A filter baffle 11 is installed on the rear end plate of the recycling box 1 and is located in the rear connection port 22. Through the above structural form, the external exhaust fan can work to generate negative pressure at the absorption hood 3, absorb the dust and debris generated during the cutting process and send them into the recycling box 1. When the dust and debris enter the recycling box 1, due to the sudden increase in the air passage area resulting in a decrease in flow velocity, most of the dust and debris will fall to the bottom of the recycling box 1, while the filter baffle 11 is used to block the lighter part, playing a recycling role.

[0041] As Figure 3 - Figure 5 As shown in the figure, a long-stroke hydraulic cylinder 4 is installed on the recycling box 1, and a pressing and cleaning integrated mechanism 5 is installed on its output shaft. Among them, the pressing and cleaning integrated mechanism 5 includes an upper substrate 51. A pressing plate 53 is connected to the upper substrate 51 through a sliding connector 52. An electric cleaning roller 54 is installed at one end of the upper substrate 51 close to the filter baffle 11. A brush layer 55 that fits the filter baffle 11 is sleeved outside the electric cleaning roller 54. Through the above structural form, after absorbing for a period of time, the exhaust fan stops working. At this time, the long-stroke hydraulic cylinder 4 works to drive the pressing and cleaning integrated mechanism 5 to move down, and finally the dust and debris accumulated at the bottom of the recycling box 1 are squeezed and gathered by the pressing plate 53, which is convenient for taking out and transporting. And during the above process, the electric cleaning roller 54 will move synchronously, and the surface of the filter baffle 11 is cleaned by driving the rotation of the brush layer 55, avoiding a significant reduction in the air passage area due to excessive waste adhering to the surface of the filter baffle 11.

[0042] As Figure 2 - Figure 3 As shown in the figure, the bottom plate of the recycling box 1 is an inclined plate sloping towards one side, and a wedge-shaped pressing block 531 is installed on the lower end surface of the pressing plate 53. The bottom surface of the wedge-shaped pressing block 531 is parallel to the bottom plate of the recycling box 1. Through the above structural form, after the wedge-shaped pressing block 531 squeezes the waste debris into a whole, it is convenient to take out the compressed waste through the inclined surface.

[0043] In addition, a discharge port 12 is opened at the bottom of the recycling box 1, and a closed cover plate 121 that is rotatably connected to the recycling box 1 is provided outside the discharge port 12. Through the above structural form, the opened discharge port 12 provides a necessary structural basis for taking out the compressed waste, while the closed cover plate 121 can ensure the airtightness of the internal space when the exhaust fan is working.

[0044] As Figure 3As shown in the figure, a circular through-hole is provided in the center of the upper substrate 51. The output shaft end of the long-stroke hydraulic cylinder 4 passes through the circular through-hole and is fixedly connected to the pressing plate 53. Through the above structural form, it is possible to directly drive the pressing plate 53 to move by the long-stroke hydraulic cylinder 4, providing a necessary structural basis for the pressing plate 53 to extrude debris waste and drive the upper substrate 51 to move.

[0045] As Figure 3 - Figure 5 shown, the sliding connecting member 52 includes a guide rod 521 and a cylinder seat 522. Among them, the guide rod 521 is slidably arranged in the upper substrate 51, and the bottom end is fixedly connected to the pressing plate 53. The cylinder seat 522 is sleeved outside the guide rod 521 and fixedly connected to the upper substrate 51. An anti-disengagement end piece 523 is fixedly connected to the top end of the guide rod 521. A return spring 524 is sleeved outside the guide rod 521. The two ends of the return spring 524 respectively abut against the anti-disengagement end piece 523 and the cylinder seat 522. Through the above structural form, when there is no external force, the upper substrate 51 will always be in contact with the pressing plate 53 under the thrust of the return spring 524, that is, it will move synchronously with the output shaft end of the long-stroke hydraulic cylinder 4 to drive the electric cleaning roller 54 to move to complete the cleaning of the surface of the filter baffle 11. When the upper substrate 51 is limited, at this time, the long-stroke hydraulic cylinder 4 can still continue to press down the pressing plate 53 to extrude and shape the debris waste.

[0046] Based on the above working principle, two groups of limiting blocks 14 are fixedly arranged on the inner wall of the recycling box 1. Side abutting plates 511 are fixedly arranged on both sides of the upper substrate 51. The positions of the side abutting plates 511 correspond to those of the limiting blocks 14 one by one. Through the above structural form, the combination of the side abutting plates 511 and the limiting blocks 14 can play a role in limiting the upper substrate 51, avoiding the situation that the electric cleaning roller 54 continues to move down and collides with the recycling box 1.

[0047] As Figure 3 - Figure 4 shown, a roller cover 56 fixedly connected to the upper substrate 51 is sleeved outside the electric cleaning roller 54, and the end of the roller cover 56 does not contact the filter baffle 11. Through the above structural form, the roller cover 56 can seal the upper space of the electric cleaning roller 54, avoiding the situation that the electric cleaning roller 54 brings debris dust into the upper space during rotation and cannot be discharged.

[0048] In addition, a circle of closed frame 13 is fixedly provided on the inner wall of the recycling box 1, and the lower end surface of the closed frame 13 can fit tightly with the upper base plate 51 and the roller cover 56, and a layer of rubber cushion is attached to the lower end surface of the closed frame 13. Through the above-mentioned structural form, when the output shaft of the long-stroke hydraulic cylinder 4 is in the initial stroke, that is, when the exhaust fan works to absorb dust and debris, the closed frame 13 fits tightly with the upper base plate 51 and the roller cover 56, and the recycling box 1 is divided into two isolated spaces, that is, the lower space is the collection space, and the upper space is the working space, which can effectively prevent dust and debris from entering the upper space and causing subsequent cleaning difficulties.

[0049] like Figure 6 As shown, the absorption hood 3 includes a trapezoidal hood 31, which is tightly connected to the front connection port 21 through a pipe connected to the rear side. At the same time, a cover plate 32 is installed on the front end surface of the trapezoidal hood 31, and a plurality of through holes distributed in an array are opened on the cover plate 32. Through the above-mentioned structural form, when the exhaust fan is working, negative pressure will be generated in the trapezoidal hood 31, and dust and debris will be sucked into the recovery box 1 through the through holes on the cover plate 32, thereby playing a recovery role.

[0050] In addition, the filter baffle 11 includes a frame 111 detachably connected to the recycling box 1, and a filter screen 112 is detachably installed in the frame 111. Through the above-mentioned structural form, it is convenient for maintenance personnel to replace the filter screen 112, so that the filter baffle 11 can always maintain a large wind flow area and a waste blocking function.

[0051] The use principle and use process of the present invention:

[0052] The rock wool processing waste recycling can work through an external exhaust fan, generate negative pressure in the trapezoidal cover 31, and suck the dust and debris into the recycling box 1 through the through holes on the cover plate 32, so as to play a recycling role. When the dust and debris enter the recycling box 1, the flow rate decreases due to the sudden increase in the wind area, so most of the dust and debris will fall to the bottom of the recycling box 1, and the filter baffle 11 is used to block the lighter part, so as to play a recycling role.

[0053] After absorbing for a period of time, the exhaust fan stops working. At this time, the long-stroke hydraulic cylinder 4 works to drive the material pressing and cleaning integrated mechanism 5 to move downward, and finally squeezes and gathers the dust and debris accumulated at the bottom of the recovery box 1 through the pressure plate 53, so that the waste can be stroked as a whole as possible to facilitate taking out and transportation. In the above process, the electric cleaning roller 54 will move synchronously and clean the surface of the filter baffle 11 by driving the brush layer 55 to rotate, so as to avoid excessive waste adhering to the surface of the filter baffle 11 and significantly reducing the wind passing area.

[0054] In the above structure, since the upper substrate 51 and the pressing plate 53 are connected by the sliding connecting member 52, when there is no external force, the upper substrate 51 will always be in contact with the pressing plate 53 under the thrust of the reset spring 524, that is, it will move synchronously with the output shaft end of the long-stroke hydraulic cylinder 4 to drive the electric cleaning roller 54 to move to complete the cleaning of the surface of the filter baffle 11. When the upper substrate 51 is limited, at this time, the long-stroke hydraulic cylinder 4 can still continue to press down the pressing plate 53 to extrude and shape the debris and waste. In addition, the combined action of the side abutting plate 511 and the limiting block 14 can play a role in limiting the upper substrate 51 to avoid the situation that the electric cleaning roller 54 continues to move down and collides with the recycling box 1.

[0055] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
