Description

Technical Field

[0001] This utility model relates to the field of rock wool production technology, specifically to a raw material screening device for rock wool production. Background Technology

[0002] Rock wool originated in Hawaii. After the first volcanic eruption on the island of Hawaii, the islanders found strands of soft, melted rock on the ground. This was the first rock wool fiber that humans recognized. The production process of rock wool actually simulates the natural process of the Hawaiian volcanic eruption. Rock wool products use high-quality basalt, dolomite and other raw materials as the main raw materials. After being melted at a high temperature of over 1450℃, the fibers are spun into fibers using an internationally advanced four-axis centrifuge. At the same time, a certain amount of binder, dust-proofing oil and water-repellent agent are sprayed in. The fibers are then collected by a cotton collecting machine, and after being laid in a pendulum process and three-dimensional method, they are cured and cut to form rock wool products of different specifications and uses.

[0003] For example, Chinese patent CN217774742U discloses a raw material screening device for rock wool board production. This patent uses a screen to screen the raw materials entering the machine, a mounting frame to fix the screen, and a vibrator to make the mounting frame drive the screen to vibrate frequently, so that the raw materials on the screen are dispersed and have more sufficient contact with the screen, thereby improving the screening efficiency, reducing the number of repeated screenings, and preventing qualified raw materials from being discarded and wasting resources. However, in this solution, when screening a large amount of rock wool raw materials, the rock wool raw materials may pile up, making the movement speed of the rock wool raw materials slow down, which may reduce the screening effect and affect the screening of rock wool raw materials, thus having certain limitations.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A raw material screening device for rock wool production includes: a supporting base plate 1, a screening chamber 2 disposed on the top surface of the supporting base plate 1, a PLC controller fixedly installed on one side of the supporting base plate 1, and an adjustment component disposed on the top surface of the supporting base plate 1 for adjusting the tilt angle of the screening chamber 2. The adjustment component includes: a first support hole 3, the first support hole 3 being opened on the top surface of the supporting base plate 1, a hydraulic cylinder 4 fixedly sleeved on the inner circular wall of the first support hole 3, a push plate 5 fixedly installed on the top surface of the telescopic shaft of the hydraulic cylinder 4, second support holes 6 respectively opened on both sides of the push plate 5, an elliptical rotating column 7 movably sleeved inside the push plate 5, the elliptical rotating column 7 movably sleeved with the second support holes 6, and a first fixing plate 8 fixedly installed on one side of the push plate 5. A drive motor 9 is fixedly installed on the top surface of the fixed plate 8. The drive motor 9 is electrically connected to the PLC controller. One end of the drive shaft of the drive motor 9 is fixedly installed to the elliptical rotating column 7. A first support plate 10 is fixedly installed on the top surface of the support base plate 1. First circular through holes are opened on both sides of the first support plate 10. A support column 12 is movably sleeved on the inner circular wall of the first circular through hole. The support column 12 is fixedly installed to the screening chamber 2. A second fixed plate 13 is fixedly installed on one side of the screening chamber 2. A second circular through hole is opened on the top surface of the second fixed plate 13. A feed hopper 15 is fixedly sleeved on the inner circular wall of the second circular through hole. A screening frame 11 is fixedly sleeved inside the screening chamber 2. A third circular through hole is opened on the top surface of the screening chamber 2. A telescopic tube 14 is fixedly sleeved on the circular wall surface. The telescopic tube 14 is fixedly sleeved with the feed hopper 15. Through the provided support base plate 1, when the user needs to screen the rock wool raw material on the support base plate 1, the provided hydraulic cylinder 4 is activated to push the push plate 5 upwards, causing the elliptical rotating column 7 to move. This causes the elliptical rotating column 7 to move the bottom of the screening chamber 2 upwards. Then, through the provided feed hopper 15, the user pours the rock wool raw material into the telescopic tube 14 and the interior of the screening chamber 2, so that the rock wool raw material falls to the top left position of the screening frame 11. At this time, the provided drive motor 9 is activated to drive the elliptical rotating column 7 to rotate. Because the cross-sectional shape of the elliptical rotating column 7 is elliptical, When the elliptical rotating column 7 rotates, it causes the left side of the screening chamber 2 to vibrate up and down, which in turn causes the internal screening frame 11 to shake and screen the rock wool raw material. Since the left side of the screening frame 11 is higher and the right side is lower, the rock wool raw material gradually slides downwards. At the same time, the screening frame 11 is wavy, which can prevent the raw material particles from sliding down the top surface of the screening frame 11 too quickly. The screening frame 11 then screens the dust and impurities in the rock wool raw material. The screened impurities such as dust are then discharged from the interior of the screening chamber 2 through the fixed pipe 22, and then discharged through the discharge pipe 21. However, there may be cases where the raw material slides down the top surface of the screening frame 11 too slowly.At this point, the hydraulic cylinder 4 can be activated to push the push plate 5 to increase the tilt angle of the screening chamber 2. When the raw material slides down the top surface of the screening frame 11 too quickly, causing impurities to be discharged from the inside of the screening chamber 2 through the discharge pipe 21 without being screened out, the tilt angle of the screening chamber 2 can be decreased, thereby adjusting the sliding speed of the raw material. This achieves the combined effect of adjusting the tilt angle of the screening chamber 2, allowing for adjustment of the sliding speed of the rock wool raw material particles inside the screening chamber 2. This prevents dust from not being completely screened out due to excessive sliding speed, while also preventing the raw material discharge speed from being too slow, maintaining a better balance between the raw material speed and the screening effect. Simultaneously, the vibrating motor 25 prevents blockage at the bottom of the screening chamber 2, thus avoiding any impact on the screening operation.

[0024] Example 2

[0025] Based on the above embodiment 1, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The top surface of the screening chamber 2 is provided with a fixing hole 16. A flip plate 17 is movably sleeved inside the fixing hole 16. Two hinges are fixedly installed on the top surface of the flip plate 17. The screening chamber 2 and the flip plate 17 are connected by the hinges. A buckle head 18 is fixedly installed on the top surface of the flip plate 17. Two buckle bottoms 19 are fixedly installed on the top surface of the screening chamber 2. A discharge hole 20 is provided on one side of the screening chamber 2. A discharge pipe 21 is fixedly sleeved on the inner circular wall of the discharge hole 20. A rectangular through hole is provided on one side of the screening chamber 2. A fixing pipe 22 is fixedly sleeved inside the rectangular through hole.

[0026] Example 3

[0027] Based on the above embodiment 1 or 2, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The top surface of the support base plate 1 is provided with a rectangular groove, and a movable column 23 is provided inside the rectangular groove. Several second support plates 24 are fixedly installed on the bottom surface of the support base plate 1. A vibration motor 25 is fixedly installed on the bottom surface of the screening chamber 2. The vibration motor 25 is electrically connected to the PLC controller.

[0028] Working principle: Please refer to Figures 1-5As shown, when the user needs to screen the rock wool raw material on the support base plate 1, the hydraulic cylinder 4 is activated to push the push plate 5 upward, causing the elliptical rotating column 7 to move upward. This causes the elliptical rotating column 7 to move the bottom of the screening chamber 2 upward. Then, the user pours the rock wool raw material into the telescopic pipe 14 and the screening chamber 2 through the feed hopper 15. The rock wool raw material falls to the top left side of the screening frame 11. At this time, the drive motor 9 is activated. The drive motor 9 drives the elliptical rotating column 7 to rotate. Because the cross-sectional shape of the elliptical rotating column 7 is elliptical, its rotation causes the left side of the screening chamber 2 to vibrate up and down. This causes the internal screening frame 11 to agitate and screen the rock wool raw material. Since the left side of the screening frame 11 is higher than the right side, the rock wool raw material gradually slides downwards. Simultaneously, the wavy shape of the screening frame 11 prevents raw material particles from sliding too quickly down the top surface of the frame. Furthermore, the screening frame 11 effectively removes dust and impurities from the rock wool raw material. The material is screened to separate impurities such as dust. The screened impurities are then discharged from the screening chamber 2 through a fixed pipe 22. The rock wool raw material is then discharged through a discharge pipe 21. However, there is a possibility that the raw material slides too slowly down the top surface of the screening frame 11. In this case, the hydraulic cylinder 4 can be activated to push the push plate 5 to increase the tilt angle of the screening chamber 2. When the raw material slides too fast down the top surface of the screening frame 11, causing impurities to be discharged from the screening chamber 2 through the discharge pipe 21 without being screened, the screening process can be accelerated. By reducing the tilt angle of bin 2, the downward speed of the raw material is adjusted, thereby achieving the combined effect of adjusting the tilt angle of bin 2. This allows for adjustment of the downward speed of the rock wool raw material particles inside bin 2, preventing dust from not being completely screened out due to excessive downward speed, while also preventing the raw material discharge speed from being too slow. This maintains an optimal balance between the raw material speed and the screening effect. At the same time, the installed vibrating motor 25 prevents blockage at the bottom of bin 2, thus avoiding any impact on the screening of raw materials.
