Description

Technical Field

[0001] This application relates to the field of coating production equipment, and more specifically, to emulsion-type shell coating production equipment and its preparation method. Background Technology

[0002] The preparation of emulsion-type shell coatings requires the shells to be crushed to produce shell powder, which necessitates the use of a shell crushing device. During the entire preparation process, the crushed shells need to be sieved. The crushed shells need to be removed from the crushing device and placed on a sieving device for further sieving. After sieving, the larger shell particles need to be crushed again. Therefore, crushing and sieving cannot be carried out simultaneously, which increases the shell powder preparation process, ultimately increasing the preparation time and reducing the efficiency of shell powder preparation.

[0008] According to this application, the rotating outer barrel includes a barrel body and a first motor. The first motor is fixedly connected to the frame, the barrel body is rotatably connected to the frame, the inner liner is rotatably connected to the inner side of the barrel body, and the output end of the first motor is drively connected to the barrel body.

[0009] According to this application, the first motor output end is provided with a first gear, and the barrel body is provided with a first gear ring, and the first gear is meshed with the first gear ring.

[0010] According to this application, the powder suction box includes a box body, a baffle plate, a pull-out plate, and a discharge barrel. The bottom of the box body is fixedly connected to the upper part of the discharge barrel, the discharge barrel is fixedly connected to the frame, the baffle plate is fixedly connected inside the box body, and multiple baffle plates are provided. The pull-out plate is located between the box body and the discharge barrel, and the pull-out plate is slidably connected to the upper part of the discharge barrel.

[0011] According to this application, the pull-out plate includes a plate body and a first telescopic member, the end of the first telescopic member is fixedly connected to one side of the discharge barrel, the output end of the first telescopic member is fixedly connected to one side of the plate body, and the plate body is slidably connected to the upper part of the discharge barrel.

[0012] According to this application, the filter element includes a filter cartridge, a filter element, and a rotating cleaning brush. The filter cartridge is fixedly connected to one side of the housing. The filter element is installed inside one side of the filter cartridge. The rotating end of the rotating cleaning brush cleans one side of the filter element. The input end of the exhaust fan is connected to the filter cartridge.

[0013] According to this application, the rotating cleaning brush includes a brush body and a second motor, the second motor is fixedly connected to the housing, and the brush body is drivenly connected to the output end of the second motor.

[0014] In the process of preparing shell powder, the shells need to be coarsely crushed into small particles, and then the particles need to be crushed into powder according to production needs. Therefore, two sets of equipment are required: a coarse crushing equipment and a powder grinding equipment. The shell particles inside the coarse crushing equipment need to be removed and transported to the powder grinding equipment, which increases the crushing time and reduces the efficiency of shell powder preparation.

[0015] According to this application, a grinding assembly is also included, the grinding assembly comprising a first drive shaft, a second drive shaft, a support, a receiving hopper, an upper grinding block, a lower grinding block, and a blower. Multiple receiving hoppers, upper grinding blocks, and lower grinding blocks are provided. The first drive shaft and the second drive shaft are rotatably connected to the frame. One end of the first drive shaft is connected to the outside of the rotating outer barrel, and the other end of the first drive shaft is connected to the upper part of the second drive shaft. The bottom of the second drive shaft is connected to one of the lower grinding blocks, and adjacent lower grinding blocks are connected. The receiving hopper is fixedly connected to the frame, the upper grinding block is fixedly connected to the bottom of the receiving hopper, the support is fixedly connected to the frame, the lower grinding block is rotatably connected to the support, and the blower is fixedly connected to the frame. The output end of the blower is connected to the upper grinding block.

[0016] The rotation of the outer barrel causes the shells and spheres inside to rotate. The spheres grind the shells. During the grinding process, powder and small shell particles pass through the inner liner plate into the area between the inner liner plate and the outer barrel. At this point, the inner liner plate is limited by the first limiting ring and cannot rotate on its own. Therefore, the rotation of the outer barrel will cause the inner liner plate to rotate. When the inner liner plate rotates to the upper part of the inner side of the outer barrel, the first limiting ring no longer limits the inner liner plate. At this point, the inner liner plate will rotate on its own under the action of gravity. At this time, the powder and shell particles are poured out and enter the receiving hopper. The shell particles enter the upper grinding block through the receiving hopper. The rotation of the outer barrel also drives the first drive shaft to rotate, which in turn drives the second drive shaft to rotate. The second drive shaft drives the lower grinding block to rotate, and the rotation of the lower grinding block can grind the shell particles inside the upper grinding block. While grinding, the blower delivers air into the upper grinding block, blowing out the ground powder and spreading it again inside the rotating outer barrel, making it easier for the powder suction head to extract the powder. Throughout the process, the bottom of the rotating outer barrel, in conjunction with the spheres, performs ball grinding of the seashells. As the outer barrel rotates, the coarsely ground particles and powder are poured into the receiving hopper. In the upper and middle part of the inner side of the rotating outer barrel, the upper and lower grinding blocks are used to grind the seashell particles. The blower blows air into the upper grinding block, which in turn blows air between the upper and lower grinding blocks. The ground seashell powder is dispersed inside the rotating outer barrel, making it easier for the powder suction head to extract the powder into the powder suction box. Throughout the process, the ball grinding and grinding of the seashells, i.e., coarse and fine grinding, are achieved directly inside the rotating outer barrel, reducing the steps in seashell powder preparation and improving the efficiency of seashell powder preparation.

[0017] According to this application, a second gear is provided on one side of the first transmission shaft, a first bevel gear is provided on the other side of the first transmission shaft, a second bevel gear is provided on the upper part of the second transmission shaft, a gear set is provided at the bottom of the second transmission shaft, a second gear ring is provided on the outside of the lower grinding block, the second gear is connected to the outside of the rotating outer barrel, the first bevel gear is meshed with the second bevel gear, and the gear set is meshed with the second gear ring.

[0018] According to this application, both the upper grinding block and the lower grinding block are provided with grooves spaced apart, and the output end of the blower is connected to the inside of the groove in the upper grinding block.

[0019] In the process of preparing shell powder, equipment is needed to grind the shells into powder, and then the shell powder needs to be exported. Dust often occurs when exporting the shell powder, which is not environmentally friendly and wastes resources.

[0020] According to this application, it also includes a discharge assembly, which includes a linear slide rail and a material bucket. The frame is provided with a swaying frame, which includes a support, springs, and a vibration motor. The bottom of the powder suction box is provided with a discharge port, which is provided with a lifting and sealing nozzle. The bottom of the support is slidably connected to the frame. The springs are symmetrically arranged, with one side of the spring fixedly connected to the frame and the other side of the spring fixedly connected to the support. The bottom of the powder suction box is fixedly connected to the upper part of the support. The vibration motor is fixedly connected to one side of the support. The sliding end of the linear slide rail is slidably connected to the upper part of the frame. The material bucket is placed on the upper part of the sliding end of the linear slide rail, and the bottom of the lifting and sealing nozzle is inserted into the upper part of the material bucket.

[0021] The sliding end of the linear guide rail moves the material bucket to the bottom of the discharge port. The lifting end of the lifting sealing nozzle rises and falls, sealing the nozzle at the top of the material bucket. At this time, the output end of the first telescopic component moves the plate away from the box, connecting the discharge bucket and the box. The shell powder remaining inside the box falls into the discharge bucket and enters the material bucket through the discharge port. The vibration motor operates, vibrating the support frame. Under the action of the spring, the support frame sways, which in turn causes the discharge bucket and the box to shake, dislodging the shell powder remaining inside the box and discharge bucket. After the shell powder enters the material bucket, the output end of the first telescopic component resets the plate, and the lifting sealing nozzle rises. The sliding end of the linear guide rail moves the material bucket out, achieving material discharge. Throughout the process, the lifting sealing nozzle inserted at the top of the material bucket achieves sealed discharge, reducing dust from the shell powder and minimizing resource waste.

[0022] According to this application, the linear guide rail includes a third motor, a lead screw, and a slide plate. The slide plate is slidably connected to the upper part of the frame, the lead screw is rotatably connected to the frame, the third motor is fixedly connected to the frame, the output end of the third motor is fixedly connected to one end of the lead screw, the lead screw is threadedly connected to the slide plate, and the material bucket is placed on the upper part of the slide plate.

[0023] According to this application, the lifting sealing nozzle includes a second telescopic member and a sealing nozzle. The sealing nozzle is slidably connected to the inner wall of the discharge port. The end of the second telescopic member is fixedly connected to the bottom of the powder suction box, and the output end of the second telescopic member is fixedly connected to the sealing nozzle.

[0024] The method for producing emulsion-type shell coating according to the second aspect of this application includes the emulsion-type shell coating production equipment described in the first aspect of this application, and the following steps:

[0025] S1. Place the pre-processed shells inside the rotating outer barrel. The rotating outer barrel will cause the sphere, inner liner and shells to rotate. Under the action of gravity, the sphere will rotate inside the rotating outer barrel, grinding the shells.

[0026] S2. During the ball milling process, some powder and small particles will first appear. The powder and small particles enter between the inner liner plate and the rotating outer barrel. The rotating outer barrel rotates the inner liner plate. At this time, the inner liner plate is limited by the first limiting ring strip, that is, the inner liner plate will not rotate on its own. When the rotating outer barrel rotates the inner liner plate to the upper part of the inner side of the rotating outer barrel, the first limiting ring strip no longer limits the inner liner plate. At this time, the inner liner plate will rotate on its own under the action of gravity. The space between the inner liner plate and the rotating outer barrel will open, and the powder and small particles will be poured out and scattered inside the rotating outer barrel.

[0027] S3. Small particles will fall faster under the influence of gravity, while powder will fall slower. At this time, the input end of the exhaust fan draws air from the filter element, the filter element draws air from the inside of the powder suction box, the powder suction box draws air from the inside of the powder suction head, and the powder suction head draws air and powder from the inside of the rotating outer barrel, drawing the powder into the powder suction box, filtering it, and finally filtering it through the filter element before being drawn out and discharged to the outside by the exhaust fan.

[0028] S4. The powder remains inside the powder suction box, and the powder is then extracted from inside the powder suction box.

[0029] The beneficial effects of the emulsion-type shell coating production equipment according to the embodiments of this application are:

[0030] 1. It allows seashells to be placed inside a rotating outer barrel. The rotation of the outer barrel, in conjunction with the sphere, crushes the seashells. During crushing, the powder and seashell particles will enter between the inner liner and the rotating outer barrel under the action of gravity. The rotating outer barrel will rotate the powder and particles to the upper part of the inner side of the rotating outer barrel and pour them out. It is equivalent to scattering the powder and particles inside the rotating outer barrel. At the same time, it can also flip the particles from the bottom of the inner side of the rotating outer barrel to the top of the seashells inside the rotating outer barrel, which facilitates better crushing of the seashells.

[0031] 2. Taking advantage of the slow descent speed and particle size of the powder, the air inside the powder suction head can be extracted using a powder suction box and a blower. The powder suction head then draws the powder into the powder suction box. Therefore, it is possible to crush the seashells while simultaneously extracting the resulting powder into the powder suction box, thereby reducing the steps in the seashell powder preparation process and improving the efficiency of seashell powder preparation.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] The following description, with reference to the accompanying drawings, describes an emulsion-type shell coating production apparatus according to an embodiment of this application.

[0048] like Figures 1-12 As shown, the emulsion-type shell coating production equipment according to an embodiment of this application includes a frame 100 and a ball mill assembly 200.

[0049] The ball mill assembly 200 includes a rotating outer barrel 210, an inner liner plate 220, balls 230, a powder suction head 240, a powder suction box 250, a filter element 260, and a blower 270. The rotating outer barrel 210 is rotatably connected to the frame 100. Multiple inner liner plates 220 are provided, with one side of each inner liner plate 220 rotatably connected to the interior of the rotating outer barrel 210. The multiple inner liner plates 220 are arranged in an array along the inner wall of the rotating outer barrel 210. A first limiting ring 110 is provided on one side of the frame 100 inside the rotating outer barrel 210. One side of each inner liner plate 220 is connected to the first limiting ring 110. 10. Sliding connection, the inner liner 220 rotates to the upper inner side of the rotating outer barrel 210, the first limiting ring 110 no longer limits the inner liner 220, multiple balls 230 are provided, multiple balls 230 are placed inside the rotating outer barrel 210, one side of the powder suction head 240 is fixedly connected to the frame 100, the other side of the powder suction head 240 extends into the rotating outer barrel 210, the powder suction head 240 is connected to one side of the powder suction box 250, the filter element 260 is set on the other side of the powder suction box 250, the input end of the exhaust fan 270 is connected to the powder suction box 250 through the filter element 260.

[0050] The working process of an emulsion-type shell coating production equipment according to a specific embodiment of this application is described below with reference to the accompanying drawings;

[0051] First, the shell is placed inside the barrel 211, which is also the inside of multiple inner lining plates 220. The barrel lid 120 is rotated to cover one side of the barrel 211. At this time, the output end of the first motor 212 drives the barrel 211 to rotate. The rotation of the barrel 211 will drive the multiple inner lining plates 220 to rotate. The inner lining plates 220 will drive the sphere 230 and the shell to rotate. Under the action of gravity, the sphere 230 and the shell always move in the bottom area inside the barrel 211. The sphere 230 grinds the shell.

[0052] Then, during the ball milling process, the powder and particles that appear will enter the area between the inner liner plate 220 and the barrel 211. At this time, the first limiting ring 110 and the second limiting ring 121 limit the inner liner plate 220 so that the inner liner plate 220 will not rotate. When the inner liner plate 220 is rotated to the upper part of the inner side of the barrel 211, the first limiting ring 110 and the second limiting ring 121 no longer limit the inner liner plate 220. At this time, the inner liner plate 220 will rotate, causing the powder and particles to fall out.

[0053] Finally, the powder and granules diffuse inside the barrel 211. Under the influence of gravity, the granules move faster than the powder. The input end of the exhaust fan 270 draws air from inside the filter cartridge 261. The filter cartridge 261 draws air from inside the housing 251 through the filter element 262. The air inside the housing 251 contains powder. At this time, the output end of the second motor 2632 drives the brush body 2631 to rotate, cleaning one side of the filter element 262. The housing 251 draws air from inside the powder suction head 240, which then draws the powder diffused inside the barrel 211. Finally, the powder will remain at the bottom of the housing 251 and be discharged through the discharge barrel 254.

[0054] Therefore, since the shells can be crushed while the resulting powder is being extracted into the powder collection box 250, the shell powder preparation process is reduced and the efficiency of shell powder preparation is improved.

[0055] In addition, the emulsion-type shell coating production equipment according to the embodiments of this application also has the following additional technical features:

[0056] According to this application, such as Figure 2 As shown, a barrel cover 120 is provided on one side of the frame 100, and a second limiting ring strip 121 is provided on the barrel cover 120. The other side of the inner liner 220 is rotatably connected to the second limiting ring strip 121.

[0057] According to this application, such as Figure 3 As shown, a transparent plate 122 is provided in the middle of one side of the bucket lid 120, and an air inlet pipe 123 is provided at the bottom of the bucket lid 120. The air inlet pipe 123 is equipped with a one-way valve 124.

[0058] According to this application, such as Figure 4 As shown, the rotating outer barrel 210 includes a barrel body 211 and a first motor 212. The first motor 212 is fixedly connected to the frame 100, the barrel body 211 is rotatably connected to the frame 100, the inner liner 220 is rotatably connected to the inner side of the barrel body 211, and the output end of the first motor 212 is connected to the barrel body 211 for transmission.

[0059] According to this application, such as Figure 4 As shown, the output end of the first motor 212 is provided with a first gear 213, and the outside of the barrel 211 is provided with a first gear ring 214, and the first gear 213 and the first gear ring 214 are meshed and connected.

[0060] According to this application, such as Figure 6As shown, the powder suction box 250 includes a box body 251, a baffle plate 252, a pull-out plate 253, and a discharge bucket 254. The bottom of the box body 251 is fixedly connected to the upper part of the discharge bucket 254, and the discharge bucket 254 is fixedly connected to the frame 100. The baffle plate 252 is fixedly connected inside the box body 251, and multiple baffle plates 252 are provided. The pull-out plate 253 is located between the box body 251 and the discharge bucket 254, and the pull-out plate 253 is slidably connected to the upper part of the discharge bucket 254.

[0061] According to this application, such as Figure 6 As shown, the pull-out plate 253 includes a plate body 2531 and a first telescopic member 2532. The end of the first telescopic member 2532 is fixedly connected to one side of the discharge barrel 254, and the output end of the first telescopic member 2532 is fixedly connected to one side of the plate body 2531. The plate body 2531 is slidably connected to the upper part of the discharge barrel 254.

[0062] According to this application, such as Figure 7 As shown, the filter element 260 includes a filter element canister 261, a filter element 262, and a rotating cleaning brush 263. The filter element canister 261 is fixedly connected to one side of the housing 251. The filter element 262 is installed inside one side of the filter element canister 261. The rotating end of the rotating cleaning brush 263 cleans one side of the filter element 262. The input end of the exhaust fan 270 is connected to the filter element canister 261.

[0063] According to this application, such as Figure 7 As shown, the rotating cleaning brush 263 includes a brush body 2631 and a second motor 2632. The second motor 2632 is fixedly connected to the housing 251, and the brush body 2631 is drivenly connected to the output end of the second motor 2632.

[0064] In the process of preparing shell powder, the shells need to be coarsely crushed into small particles, and then the particles need to be crushed into powder according to production needs. Therefore, two sets of equipment are required: a coarse crushing equipment and a powder grinding equipment. The shell particles inside the coarse crushing equipment need to be removed and transported to the powder grinding equipment, which increases the crushing time and reduces the efficiency of shell powder preparation.

[0065] According to this application, such as Figures 8-10As shown, the assembly also includes a grinding component 300, which includes a first drive shaft 310, a second drive shaft 320, a support 330, a receiving hopper 340, an upper grinding block 350, a lower grinding block 360, and a blower 370. Multiple receiving hoppers 340, upper grinding blocks 350, and lower grinding blocks 360 are provided. Both the first drive shaft 310 and the second drive shaft 320 are rotatably connected to the frame 100. One end of the first drive shaft 310 is externally connected to the rotating outer barrel 210. The other end of the first drive shaft 310... One end is connected to the upper part of the second drive shaft 320, the bottom of the second drive shaft 320 is connected to a lower grinding block 360, two adjacent lower grinding blocks 360 are connected, the receiving hopper 340 is fixedly connected to the frame 100, the upper grinding block 350 is fixedly connected to the bottom of the receiving hopper 340, the support 330 is fixedly connected to the frame 100, the lower grinding block 360 is rotatably connected to the support 330, the blower 370 is fixedly connected to the frame 100, and the output end of the blower 370 is connected to the upper grinding block 350;

[0066] The outer barrel 210 rotates, causing the shells and spheres 230 inside the outer barrel 210 to rotate. The spheres 230 ball mill the shells. During the ball milling process, powder and small particles of shells pass through the inner liner 220 and enter the area between the inner liner 220 and the outer barrel 210. At this time, the inner liner 220 is limited by the first limiting ring 110 and cannot rotate on its own. Therefore, the outer barrel 210 rotates along with the inner liner 220. When the inner liner 220 rotates to the upper inner side of the outer barrel 210, the first limiting ring 110 no longer... The inner liner 220 is limited, and under gravity, it rotates, causing the powder and shell particles to be poured out. The poured-out powder and shell particles enter the receiving hopper 340, and the shell particles enter the upper grinding block 350. Simultaneously, the rotation of the outer barrel 210 drives the first drive shaft 310, which in turn drives the second drive shaft 320, which in turn drives the lower grinding block 360. The rotation of the lower grinding block 360 allows it to interact with the upper grinding block 350. The shell particles are ground, and while grinding, the blower 370 delivers air into the upper grinding block 350 to blow out the ground powder, which then diffuses into the rotating outer barrel 210, facilitating the extraction of powder by the powder suction head 240. Throughout the process, the bottom of the rotating outer barrel 210, in conjunction with the ball 230, performs ball grinding on the shells. As the outer barrel 210 rotates, the coarsely ground particles and powder are poured into the receiving hopper 340. The upper grinding block 350 and... The lower grinding block 360 grinds the seashell particles, while the blower 370 blows air into the upper grinding block 350. The upper grinding block 350 then blows air between the upper grinding block 350 and the lower grinding block 360. The ground seashell powder is dispersed inside the rotating outer barrel 210, making it easier for the powder suction head 240 to extract the powder into the powder suction box 250. Throughout the entire process, the ball milling and grinding of the seashells, i.e., coarse and fine grinding, are carried out directly inside the rotating outer barrel 210, reducing the steps in the preparation of seashell powder and improving the efficiency of seashell powder preparation.

[0071] The sliding end of the linear guide rail 410 moves the material barrel 420 to the bottom of the discharge port 258. The lifting end of the lifting sealing nozzle 259 rises and falls, sealing the material barrel 420. At this time, the output end of the first telescopic component 2532 drives the plate 2531 to move away from the box 251. At this time, the discharge barrel 254 is connected to the box 251. The shell powder remaining inside the box 251 will fall into the discharge barrel 254 and enter the material barrel 420 through the discharge port 258. At this time, the vibration motor 133 operates, vibrating the support frame 131. 1. Under the action of spring 132, there will be shaking, which will also cause the discharge bucket 254 and the box 251 to shake, shaking down the shell powder remaining in the box 251 and the discharge bucket 254. After the shell powder enters the material bucket 420, the output end of the first telescopic member 2532 drives the plate 2531 to reset. At the same time, the lifting sealing nozzle 259 is raised, and the sliding end of the linear slide rail 410 moves the material bucket 420 out, realizing the discharge. In the whole process, the lifting sealing nozzle 259 is inserted into the upper part of the material bucket 420 to realize sealed discharge, reduce the dust of shell powder, and reduce resource waste.

[0073] According to this application, such as Figure 6 As shown, the lifting sealing nozzle 259 includes a second telescopic member 2591 and a sealing nozzle 2592. The sealing nozzle 2592 is slidably connected to the inner wall of the discharge port 258. The end of the second telescopic member 2591 is fixedly connected to the bottom of the powder suction box 250, and the output end of the second telescopic member 2591 is fixedly connected to the sealing nozzle 2592.

[0074] The method for producing emulsion-type shell coating according to the second aspect of this application includes the emulsion-type shell coating production equipment according to the first aspect of this application, and the following steps:

[0075] S1. Place the pre-processed shell inside the rotating outer barrel 210. The rotating outer barrel 210 rotates, which will drive the sphere 230, the inner liner plate 220 and the shell to rotate. Under the action of gravity, the sphere 230 will rotate inside the rotating outer barrel 210 to grind the shell.

[0076] S2. During the ball milling process, some powder and small particles will first appear. The powder and small particles enter between the inner liner plate 220 and the rotating outer barrel 210. The rotating outer barrel 210 rotates with the inner liner plate 220. At this time, the inner liner plate 220 is limited by the first limiting ring 110, that is, the inner liner plate 220 will not rotate on its own. When the rotating outer barrel 210 rotates with the inner liner plate 220 to the upper part of the inner side of the rotating outer barrel 210, the first limiting ring 110 no longer limits the inner liner plate 220. At this time, the inner liner plate 220 will rotate on its own under the action of gravity. The space between the inner liner plate 220 and the rotating outer barrel 210 will open, and the powder and small particles will be poured out and scattered inside the rotating outer barrel 210.

[0077] S3. Small particles will fall faster under the influence of gravity, while powder will fall slower. At this time, the input end of the exhaust fan 270 draws air from the filter element 260, the filter element 260 draws air from the inside of the powder suction box 250, the powder suction box 250 draws air from the inside of the powder suction head 240, and the powder suction head 240 draws air and powder from the inside of the rotating outer barrel 210, drawing the powder into the powder suction box 250 for filtration, and finally through the filter element 260 for filtration, before being drawn out and discharged to the outside by the exhaust fan 270.

[0078] S4. Keep the powder inside the powder suction box 250, and then export the powder from inside the powder suction box 250.

[0079] It should be noted that the first telescopic component 2532 and the second telescopic component 2591 are any one of the following: electric push rod, electric cylinder, hydraulic cylinder and pneumatic cylinder.
