Description

Technical Field

[0001] The invention belongs to the technical field of rock wool production equipment and relates to a rock wool collecting device for producing rock wool fireproof boards. Background Art

[0002] Rockwool board is a thermal insulation material made from high-quality basalt and dolomite, melted at high temperatures, and then added with a small amount of binder and water. It is then processed through high-speed centrifugal molding, curing, and spraying. Due to its unique physical and chemical properties, rockwool board has excellent fire resistance and is widely used in building walls, effectively protecting people's lives and property.

[0003] During the production of rock wool products, the light, fine, and loose rock wool fibers produced by centrifugal fiberization present significant challenges to subsequent production processes. Furthermore, the centrifugal fiberization process often carries with it some impurities or other defective products, which also require separation. Therefore, in the production of rock wool products, it is often necessary to collect the rock wool fibers before proceeding to the next step. This is where the fiber collector plays an indispensable role.

[0004] The prior art is a low-energy cotton collector that can automatically smooth the surface of a cotton collecting drum, as disclosed in the patent application document CN202210023994.3. The cotton collecting drum comprises a cotton collecting chamber and a cotton collecting drum. The outer side of the cotton collecting drum is a cylindrical adsorption surface, and a plurality of first through holes are evenly arranged on the adsorption surface; a detachable chip layer made of a low-adhesion material is provided on the adsorption surface, and a plurality of second through holes are provided on the chip layer, and the first through holes and the second through holes form an air flow channel; the first through hole is a circular hole, and the second through hole is cylindrical or trumpet-shaped, and the opening on the side near the hollow axis of the second through hole is an inward opening. The opening on the side away from the hollow shaft is the outer opening, the size of the inner opening is adapted to the first through hole, and the diameter of the outer opening is not larger than the inner opening; it also includes a polishing mechanism for cutting and smoothing the surface of the chip-making layer, and the polishing mechanism is arranged on the lower side of the cotton collecting drum; the device adsorbs the impurity particles on the rock wool fibers through the cuttable layer, so that the cleaning mechanism is easy to flush during cleaning, and the water consumption is small. At the same time, the cuttable layer is maintained through the polishing mechanism. Since the outer side of the cotton collecting drum of the device is a cylindrical surface, the utilization rate of the rock wool fibers by the device is low, which is not conducive to the production of rock wool boards.

[0005] In order to solve the above problems, the present invention proposes a rock wool collecting device for producing rock wool fireproof boards. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1-8 As shown, the technical solution adopted by the present invention is as follows: a cotton collection device for producing rock wool fireproof panels, comprising a base 1, a main body 4 fixedly mounted on the upper end of the base 1, a cotton collection drum 13 disposed within the main body 4, two support plates 2 fixedly mounted on either side of the upper end of the base 1, a fixed column 12 fixedly connected between the two support plates 2, and the fixed column 12 fixedly connected to the cotton collection drum 13. The cotton collection drum 13 divides the interior space of the main body 4 into a cotton collection chamber 16 and a cleaning chamber 27. The cotton collection chamber 16 contains rock wool fibers. The cleaning chamber 27 is provided with a cleaning mechanism to remove impurities and other residues remaining in the rock wool fibers.

[0030] There are rotating plates 5 on both sides of the main body 4. A plurality of fixed plates 23 are fixedly connected between the two rotating plates 5. A filter plate 25 is slidably connected between each two adjacent fixed plates 23. The bottom end of the filter plate 25 is fixedly connected to a connecting rod 26, which is fixedly connected to a sliding rod 24. Figure 6 As shown, a closed track is provided on the cotton collecting drum 13 along the circumferential direction, and the track includes a first track and a second track, and the radius of the first track is smaller than that of the second track. The first track and the second track are respectively arranged on the left and right sides of the cotton collecting drum 13. The two ends of the first track gradually extend to the second track and are connected to the second track. The sliding rod 24 is slidably connected to the track. The filter plate 25 at the second track is flush with the fixed plate 23. A groove is formed between the filter plate 25 at the first track and the fixed plate 23 to increase the adsorption amount of the rock wool fiber and increase the utilization rate of the rock wool fiber.

[0031] A first motor 3 is fixedly mounted on the upper end of the support plate 2. A gear 11 is coaxially fixedly mounted on the output end of the first motor 3. The first motor 3 rotates the gear 11. A circular groove is defined in the rotating ring plate 5. A ring gear 10 is fixedly mounted on the inner wall of the groove. The ring gear 10 meshes with the gear 11 to rotate the rotating ring plate 5.

[0032] Connecting blocks are fixedly provided at both the upper and lower ends of the outer circumference of the cotton collecting drum 13, and the two connecting blocks are fixedly connected by an arc-shaped plate on one side close to the first track. The arc-shaped plate and the outer circumference of the cotton collecting drum 13 form a negative pressure chamber 15, and the negative pressure chamber 15 is connected to the external vacuum pump through a pipe. The filter plate 25 and the arc-shaped plate are both provided with a number of trumpet-shaped holes from top to bottom. The negative pressure chamber 15 is connected to the cotton collecting chamber 16 through a hole. The gas in the negative pressure chamber 15 is extracted by the vacuum pump, so that a negative pressure is generated in the negative pressure chamber 15, and then the gas in the cotton collecting chamber 16 is extracted, so that the filter plate 25 adsorbs the rock wool fibers.

[0033] A pressure roller 8 is rotatably provided just above the cotton collecting drum 13, and the axis of the pressure roller 8 is set horizontally. The axis of the pressure roller 8 is located in the same vertical plane as the axis of the cotton collecting drum 13. The pressure roller 8 cooperates with the fixed plate 23 to extrude the rock wool fibers so that the rock wool fibers are initially formed into an initial rock wool felt. A second pulley 9 is rotatably provided on one side of the main body 4, and the second pulley 9 passes through the main body 4 and is coaxially fixedly connected to the pressure roller 8. A second motor 6 is fixedly installed on one side of the upper end of the main body 4 close to the second pulley 9, and a first pulley 7 is coaxially fixedly provided on the output end of the second motor 6, and a belt 14 is wound around the first pulley 7 and the second pulley 9. The second motor 6 rotates with the first pulley 7, and the first pulley 7 works with the belt 14, and the belt 14 rotates the second pulley 9.

[0034] The cleaning mechanism includes a spray water tank 19. A partition 21 is fixedly installed within the cleaning chamber 27, and the spray water tank 19 is fixedly mounted at the bottom end of the partition 21. The spray water tank 19 is connected to an external water pump via a pipe. A spray head is mounted on the spray water tank 19. A dryer is installed within the cleaning chamber 27 to dry the filter plate 25. The partition 21, the top surface of the cleaning chamber 27, the fixed plate 23 located on the second track, and the filter plate 25 form an air extraction chamber 22, which is connected to an external air extraction pump via a pipe. A filter screen 20 is fixedly installed on the partition 21, allowing rock wool fibers remaining in the holes of the filter plate 25 to fall onto the filter screen 20. A collection box 17 is slidably mounted at the bottom end of the cleaning chamber 27 and is slidably connected to the main body 4. A handle 18 is fixedly mounted on the outside of the collection box 17. The handle 18 allows the collection box 17 to be pulled out of the cleaning chamber 27 for cleaning.

[0035] In summary, the gas in the negative pressure chamber 15 is extracted by the vacuum pump, so that a negative pressure is generated in the negative pressure chamber 15, and then the air in the cotton collecting chamber 16 is extracted, so that the rock wool fibers are adsorbed onto the upper surface of the filter plate 25. Since a groove is formed between the filter plate 25 and the fixed plate 23, the adsorption capacity of the rock wool fibers by the filter plate 25 is increased, the utilization rate of the rock wool fibers is increased, and the quality of the rock wool fireproof board is further improved.

[0036] Then, the first motor 3 is started. This rotates gear 11, which in turn rotates ring gear 10. Ring gear 10 rotates rotating ring plate 5, which in turn rotates fixed plate 23. Fixed plate 23 rotates filter plate 25, which in turn rotates connecting rod 26. Connecting rod 26 rotates slide bar 24, which then slides on the track. As fixed plate 23 rotates filter plate 25, the first track causes slide bar 24 to move upward, carrying connecting rod 26. Connecting rod 26 gradually moves filter plate 25 upward. When fixed plate 23 rotates directly below pressure roller 8, filter plate 25 is flush with fixed plate 23.

[0037] At this time, the second motor 6 is started, and the second motor 6 rotates the first pulley 7, the first pulley 7 drives the belt 14 to transmit, the belt 14 drives the second pulley 9 to rotate, and the second pulley 9 rotates with the pressure roller 8, and the pressure roller 8 cooperates with the filter plate 25 to squeeze the rock wool fibers, so that the rock wool fibers become initial rock wool felt.

[0038] The fixed plate 23 continues to rotate with the rotating ring plate 5 until all the adsorbed rock wool fiber filter plates 25 rotate to the other side of the pressure roller 8. At this time, all the adsorbed rock wool fibers are squeezed into initial rock wool felt, and the filter plate 25 is flush with the fixed plate 23, so that the initial rock wool felt formed after being squeezed by the pressure roller 8 can be easily separated from the upper surface of the filter plate 25.

[0039] During this process, the filter plate 25 at the second track rotates to the first track. At this time, a groove is formed again between the filter plate 25 at the first track and the fixing plate 23, and the above operation is repeated.

[0040] The rotating ring plate 5 drives the filter plate 25 to rotate into the cleaning chamber 27, where the initial rock wool felt is removed from the filter plate 25. An external vacuum pump draws air from the vacuum chamber 22, creating a negative pressure there. This causes the rock wool fibers remaining in the holes of the filter plate 25 to fall onto the filter screen 20. Finally, the external water pump is activated, spraying water through the sprinkler head to clean the filter plate 25, causing impurities on the filter plate 25 to fall into the collection box 17. After rinsing is complete, the dryer is activated to dry the filter plate 25.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
