Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coating production, and specifically to a grinding device for water-based asphalt waterproof coatings. Background Technique

[0002] Water-based asphalt waterproof coating is an environmentally friendly waterproof material with emulsified asphalt as the main film-forming substance, adding water-based polymers (such as SBS, chloroprene latex, acrylate, etc.) and additives. It forms a continuous waterproof coating film after the evaporation of water, and has the characteristics of convenient construction, no solvent volatilization, and environmental friendliness. It is widely used in waterproof projects such as building roofs, basements, and tunnels. When the existing colloid mill grinds materials, since the grinding interval formed between the stator and the rotor is completely unobstructed, the materials will quickly flow out along the grinding interval during the grinding process, resulting in a short residence time of the materials in the grinding interval. As a result, the grinding time of the materials for one time is short, which is likely to cause insufficient grinding of the materials. The invention patent with the publication number of "CN115845960B" specifically discloses a preparation device for elastomer-modified asphalt waterproof coatings. Although it sets a material-blocking plate in the grinding interval to obstruct the flowing materials, thereby slowing down the flow rate of the materials in the grinding interval to increase the grinding time of the materials in the grinding interval and increase the grinding time of the materials for one time, so as to make the grinding of the materials more sufficient. However, due to the relatively fixed grinding interval between its stator and rotor, when grinding different types of waterproof coatings, it is unable to adjust the spacing of the grinding interval according to the required particle size, resulting in inconvenient use. And although it prolongs the grinding time, the waterproof coating directly discharges after one-time grinding, which cannot guarantee the relative grinding accuracy. A grinding device and method for water-based asphalt waterproof coatings are proposed to solve the above problems. Summary of the Invention

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-6 shown, the present invention provides a grinding device for water-based asphalt waterproof coating, including a bottom frame 1. Inside the bottom frame 1, there is a rotor 8, and at the top of the rotor 8, there is a stator. A grinding interval is formed between the bottom of the stator and the top of the rotor 8. The stator is divided into multiple parts and can be lifted. In the middle of the stator, there is a sieve cylinder 6 arranged layer by layer from the inside to the outside and connected to the middle top of the rotor 8 and capable of relative rotation. The side wall of the sieve cylinder 6 is penetrated with sieve holes 601, and the sieve holes 601 on each layer of the sieve cylinder 6 intersect with each other. Inside the innermost sieve cylinder 6, there is a feed pipe 201 that can separate the sieve holes 601 from the top of the rotor 8. The top of the stator can be communicated with the grinding interval. Inside the bottom frame 1, there is a sorting chamber that can blow air from the outer ring at the bottom of the rotor 8 towards the sieve cylinder 6.

[0021] It should be noted that the sieving mesh cylinder 6 can be set according to specific usage requirements. Here, the sieving mesh holes 601 intersect with each other, which means there are overlapping parts between the sieving mesh holes 601, and the overlapping parts can be ventilated, which are the sieving holes. By the relative rotation between the sieving mesh cylinders 6, the area of the overlapping parts between the sieving mesh holes 601 can be changed. The larger the overlapping area, the larger the aperture of the sieving holes, and vice versa. In this way, by the relative rotation between the sieving mesh cylinders 6, the size of the aperture can be directly changed, so as to adapt to the screening of various finenesses. Through the screening between the sieving mesh cylinders 6, unqualified particles can be screened out, so that they can be ground again to ensure the fineness of grinding. By the lifting of each part of the stator, the distance of the grinding area can be changed to adapt to the grinding of different finenesses. And each part of the stator can be lifted relatively, so as to form a stepped grinding area with gradually smaller diameters, and then a step-by-step grinding effect can be produced, thus making the grinding effect better. And the adjustment of the outermost part of the stator is adapted to the adjustment of the part intersecting with the sieving mesh holes 601, so that the fineness of grinding corresponds to the fineness of sieving. And through the blowing of air, the ground waterproof coating can be driven to move towards the sieving mesh cylinder 6 for screening.

[0022] Furthermore, as Figures 1-6 shown, the first stator 701, the second stator 702, and the third stator 703 are arranged in sequence from the outside to the inside. And an inner ring at the top of the first stator 701, the second stator 702, and the third stator 703 is provided with linkage columns 602, and the linkage columns 602 respectively pass through the sieving mesh cylinder 6 and are slidably connected thereto. The sieving mesh cylinder 6 is rotatably connected to the top of the bottom frame 1. The top ends of the linkage columns 602 extend out from the top of the sieving mesh cylinder 6 and are provided with a third external gear ring 603 that can drive the linkage columns 602 to lift and rotate.

[0023] It should be noted that driven by the linkage columns 602, the first stator 701, the second stator 702, and the third stator 703 can be lifted relatively. And the linkage columns 602 can be lifted relative to the sieving mesh cylinder 6, and at this time the sieving mesh cylinder 6 is vertically stationary relatively. Under the action of the rotation of the third external gear ring 603, the sieving mesh cylinders 6 can be lifted relatively. And under the action of the lifting of the third external gear ring 603, the linkage columns 602 can drive the first stator 701, the second stator 702, and the third stator 703 to lift relatively. Furthermore, the synchronism, coordination of the system operation and the utilization efficiency of kinetic energy are improved.

[0024] Preferably, as Figures 1-6As shown, a top frame 2 is installed on the top of the bottom frame 1, and an installation chamber 202 is formed between the top of the bottom frame 1 and the interior of the top frame 2. A driving component 5 that can drive the third outer gear ring 603 to rotate and lift simultaneously is installed in the installation chamber 202. A first servo motor 4 is installed on the top of the top frame 2. The output shaft of the first servo motor 4 extends into the installation chamber 202 and is installed with a gear 505. The gear 505 and the driving component 5 are transmitted by meshing.

[0025] It should be noted that, driven by the output shaft of the first servo motor 4, the gear 505 can rotate, and driven by the gear 505, the driving assembly 5 can drive the third outer gear ring 603 to rotate and lift accordingly, so that the lifting and lowering of each component of the stator and the rotation between the sieve cylinder 6 can be adjusted synchronously, making its operation more convenient.

[0026] Further, such as Figures 1-6 As shown, the third outer gear ring 603 connected to the top of the linkage column 602 arranged layer by layer from the inside to the outside is arranged at intervals from top to bottom, and is located in the installation chamber 202. The driving assembly 5 includes a lifting ring plate 502 and a first outer gear ring 503 corresponding to the third outer gear ring 603 one by one. An annular groove is provided in the middle of the outer side of the driving assembly 5, and the first outer toothed ring 503 is installed on the inner side of the annular groove, the outer side of the third outer toothed ring 603 extends into the annular groove and meshes with the first outer toothed ring 503, and the top and bottom of the third outer toothed ring 603 are in contact with the inner wall of the annular groove.

[0027] It should be noted that the diameter of the first outer tooth ring 503 meshing with each layer of the third outer tooth ring 603 can be different depending on the different uses, so that the third outer tooth rings 603 can rotate relative to each other, and under the relative clamping action of the lifting ring plate 502, the movement of the lifting ring plate 502 can drive the third outer tooth ring 603 to be lifted and lowered, so that the lifting and rotating of the third outer tooth ring 603 can be carried out simultaneously.

[0028] Further, such as Figures 1-6 As shown, the driving assembly 5 further includes a lifting guide column 501, a lifting slide rod 504, a connecting ring plate 506 and a second outer gear ring 507. The lifting guide column 501 is installed on the top of the bottom frame 1, and a thread is provided on the outer side of the middle section of the lifting guide column 501. The lifting ring plate 502 is threadedly connected to the threaded section on the lifting guide column 501. The connecting ring plate 506 is rotatably connected to the outer side of the bottom end of the lifting guide post 501, and the second external gear ring 507 is rotatably connected to the outer side of the top end of the lifting guide post 501. The top end of the lifting slide rod 504 is installed at the bottom of the second external gear ring 507, the bottom end of the lifting slide rod 504 is installed at the top of the connecting ring plate 506, the lifting slide rod 504 vertically passes through all the lifting ring plates 502, and the lifting ring plates 502 can slide vertically on the lifting slide rod 504. The outer side of the second external gear ring 507 meshes with the outer side of the gear 505.

[0029] It should be noted that the lifting guide post 501 is fixed relative to the bottom frame 1. When the lifting ring plate 502 rotates, the lifting ring plate 502 can perform corresponding lifting under the action of its thread. It should be noted that the thread pitches of the threaded connections between the lifting ring plates 502 may not be the same. Therefore, when the lifting ring plates 502 rotate relatively, their lifting strokes are different, so that the lifting ring plates 502 can move vertically relative to each other, so that vertical relative movement can occur between the various parts of the stator. Driven by the gear 505, the second external gear ring 507 can rotate, and through the transmission of the lifting slide rod 504, all the lifting ring plates 502 can rotate synchronously.

[0030] Specifically, as Figures 1-6 shown, the top end of the feed pipe 201 passes through the installation chamber 202 and penetrates out from the top of the top frame 2. An aggregate discharge cover 3 is installed on the outer side of the feed pipe 201 in the installation chamber 202. The air inlet at the bottom of the aggregate discharge cover 3 covers the inner side of the innermost sieve mesh cylinder 6 and can communicate with the sieve mesh holes 601. The air outlet of the aggregate discharge cover 3 extends out from the side wall of the top frame 2.

[0031] It should be noted that the bottom frame 1 and the top frame 2 are designed modularly, making their disassembly more convenient, thus making their maintenance more convenient. And under the guidance of the aggregate discharge cover 3, qualified waterproof coating particles can be collected through the aggregate discharge cover 3.

[0032] Specifically, as Figures 1-6As shown, an air supply port communicating with the sorting chamber is provided at the inner bottom of the bottom frame 1. An annular partition is installed on the outer ring of the air supply port at the inner bottom of the bottom frame 1. The top of the annular partition is rotatably connected to the bottom of the rotor 8, and a through port communicating the sorting chamber with the outside is provided on the annular partition. A bracket 901 is installed on the inner wall of the annular partition. A fan impeller 902 is connected to the middle of the bracket 901 through a bearing. The top end of the rotating shaft of the fan impeller 902 is connected to the bottom of the rotor 8. A second servo motor 10 is installed at the bottom of the bracket 901. The output shaft of the second servo motor 10 is connected to the bottom end of the rotating shaft of the fan impeller 902. The sorting chamber includes a first air supply chamber 101 and a second air supply chamber 102. The first air supply chamber 101 is located at the bottom of the rotor 8, and the second air supply chamber 102 is located at the top of the rotor 8 and the first stator 701. A gap communicating the first air supply chamber 101 and the second air supply chamber 102 is formed between the outer side of the rotor 8 and the inner wall of the bottom frame 1.

[0033] It should be noted that the outer ring of the bearing is fixed on the bracket 901, and the fan impeller 902 is installed on the inner ring of the bearing. Therefore, through the rotation of the bearing itself, the fan impeller 902 can rotate at a fixed position relative to the bracket 901. Driven by the output shaft of the second servo motor 10, the fan impeller 902 and the rotor 8 can rotate together, and through the gap between the first air supply chamber 101 and the second air supply chamber 102, the waterproof coating ground on the rotor 8 is blown, so that it can be wind-selected for discharging.

[0034] On the one hand, as Figures 1-8 shown, a first inner inclined portion 701a that gradually slopes downward from the outside to the inside is provided at the top of the first stator 701. The bottom end of the outside of the sieving cylinder 6 is provided with a return material port 604 that intersects with each other. The return material port 604 is located at the bottom of the feed pipe 201. The space between the top of the middle of the rotor 8 and the bottom of the feed pipe 201 is communicated with the second air supply chamber 102 through the return material port 604.

[0035] It should be noted that under the guidance of the first inner inclined portion 701a, the falling waterproof coating particles can fall from the return material port 604 to the top of the middle of the rotor 8, and then can be ground again through the grinding area, so that the grinding is more thorough.

[0036] On the other hand, as Figures 1-6 and Figures 9-10As shown in the figure, the top of the first stator 701 is provided with a second inner inclined portion 701b that gradually slopes downward from the outside to the inside, and the top of the second stator 702 is provided with a first outer inclined portion 702a that gradually slopes downward from the inside to the outside. The bottom ends of the second inner inclined portion 701b and the first outer inclined portion 702a point to the gap between the first stator 701 and the second stator 702. A grinding ring 11 is provided in the gap between the first stator 701 and the second stator 702. A plurality of struts 12 are installed at the bottom of the grinding ring 11, and the bottom ends of the struts 12 are installed on the top of the rotor 8.

[0037] It should be noted that under the common guidance of the second inner inclined portion 701b and the first outer inclined portion 702a, the waterproof coating particles can move towards the gap between the first stator 701 and the second stator 702. Driven by the rotor 8, the struts 12 can rotate to drive the grinding ring 11 to rotate, so that the waterproof coating particles passing through the gap between the first stator 701 and the second stator 702 can be ground and then fall back to the grinding area for grinding again.

[0038] In summary, when using this waterborne asphalt waterproof coating grinding device, the waterproof coating to be ground is added to the top in the middle of the rotor 8 through the feed pipe 201. Then, according to the specific fineness required for grinding, the first servo motor 4 is started. Driven by the output shaft of the first servo motor 4, the gear 505 rotates, and then drives the second external gear ring 507 to rotate. Driven by the second external gear ring 507, the lifting slide rod 504 can rotate to drive the first external gear ring 503 to rotate. Driven by the first external gear ring 503, the first external gear ring 503 can rotate and drive the third external gear ring 603 to rotate, so as to drive the sieve drum 6 to rotate through the linkage column 602. The sieve drums 6 are driven by the linkage columns 602 at each layer to rotate relative to each other. At this time, the relative positions of the sieve holes 601 change, changing the degree of intersection between the sieve holes 601 and thus changing the area of communication between the sieve holes 601, achieving the effect of adjusting the sieve aperture; By the rotation of the lifting ring plate 502 and the cooperation of the threads on the lifting guide post 501, the lifting ring plate 502 can be lifted and lowered. By the lifting and lowering of the lifting ring plate 502, the third external gear ring 603 can be lifted and lowered relatively, and the stator can be lifted and lowered through the linkage column 602 to adjust the spacing of the grinding area; Driven by the output shaft of the second servo motor 10, the fan impeller 902 can rotate. Driven by the rotating shaft of the fan impeller 902, the rotor 8 can rotate to grind the waterproof coating in the grinding area and convey the waterproof coating to the outer circle of the rotor 8 under the action of its rotational centrifugal force. Under the action of the rotation of the fan impeller 902, air is sent into the first air supply chamber 101 through the through-port and is sent upward from the gap between the inner wall of the bottom frame 1 and the rotor 8, so as to convey the waterproof coating ground out on the outside of the rotor 8 into the second air supply chamber 102. Then, after being jointly screened by the sieve mesh cylinder 6, the qualified particles enter the aggregate discharge cover 3 and are discharged, while the unqualified particles fall back into the grinding area again for re-grinding.
