[0014] In the process of preparing shell powder, the shells need to be coarsely crushed, that is, crushed into small particles of shell particles, and then crushed into powder according to production needs. Therefore, two sets of equipment are needed, one is the coarse crushing equipment, and the other is the powder grinding equipment. Therefore, the shell particles inside the coarse crushing equipment need to be taken out and transported to the powder grinding equipment, which will increase the crushing time and reduce the efficiency of shell powder preparation.

[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.

[0021] The sliding end of the linear slide rail moves the material barrel to the bottom of the discharge port, and the lifting end of the lifting sealing material nozzle is lifted, and the lifting sealing material nozzle is sealed and inserted into the upper part of the material barrel. At this time, the output end of the first telescopic member drives the movement of the plate body to move the plate body toward the side away from the box body. At this time, the discharge barrel and the box body are connected, and the shell powder staying in the box body will drop into the discharge barrel and enter the barrel through the discharge port. At this time, the vibration motor is operating to vibrate the support frame. Under the action of the spring, the support frame will shake, thereby also driving the discharge barrel and the box body to shake, and vibrating the shell powder remaining in the box body and the discharge barrel. When the shell powder enters the barrel, the output end of the first telescopic member drives the plate body to reset, and the lifting and sealing material nozzle is lifted, and the sliding end of the linear slide rail moves the barrel out, realizing material unloading. During the entire use process, the lifting and sealing material nozzle is inserted into the upper part of the barrel to realize sealed unloading, reduce dust from shell powder, and reduce waste of resources.

[0024] According to the second aspect of the present application, the method for producing an emulsion shell paint comprises the emulsion shell paint production equipment according to the first aspect of the present application, and the following steps:

[0025] S1. Place the shells after primary processing inside a rotating outer barrel. The rotating outer barrel will drive the sphere, the inner lining plate and the shells to rotate. Under the action of gravity, the sphere will rotate inside the rotating outer barrel to ball-mill the shells.

[0026] S2. During the ball milling process, a part of powder and small particles will appear first, and the powder and small particles will enter between the inner lining plate and the rotating outer barrel. The rotating outer barrel rotates with the inner lining plate. At this time, the inner lining plate is limited by the first limiting ring strip, that is, the inner lining plate will not rotate at this time. When the rotating outer barrel rotates with the inner lining plate to the upper inner side of the rotating outer barrel, the first limiting ring strip will no longer limit the inner lining plate. At this time, the inner lining plate will rotate under the action of gravity, and the inner lining plate and the rotating outer barrel will be opened, and the powder and small particles will be poured out and thrown inside the rotating outer barrel;

[0027] S3. Small particles will fall faster under the action of gravity, while powder will fall slower. At this time, the input end of the exhaust fan extracts air from the filter element, and the filter element extracts air from the inside of the powder suction box. The powder suction box extracts air from the inside of the powder suction head. The powder suction head extracts air and powder from the inside of the rotating outer barrel, and extracts the powder into the powder suction box, filters it through the powder suction box, and finally filters it through the filter element, and then extracts it through the exhaust fan and discharges it to the outside.

[0028] S4: The powder stays in the powder suction box and is discharged from the powder suction box.

[0030] 1. The shells can be placed inside the rotating outer barrel, and the rotating outer barrel is rotated to cooperate with the sphere to crush the shells. During crushing, the powder and shell particles will enter between the inner lining plate and the rotating outer barrel under the action of gravity. The rotating outer barrel rotates the powder and particles to the upper part of the inner side of the rotating outer barrel and pours them out, which is equivalent to throwing the powder and particles inside the rotating outer barrel. At the same time, the particles can also be turned from the bottom of the inner side of the rotating outer barrel to the upper part of the shell inside the rotating outer barrel, which is convenient for better implementation of the shell crushing operation;

[0031] 2. Taking advantage of the slow falling speed of powder and particles, the powder suction box and exhaust fan can be used to extract the air inside the powder suction head, and the powder suction head draws the powder into the powder suction box. Therefore, the shells can be crushed while the crushed powder is extracted into the powder suction box, thereby reducing the process of shell powder preparation and improving the efficiency of shell powder preparation.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] The following describes the emulsion shell paint production equipment according to an embodiment of the present application with reference to the accompanying drawings.

[0048] like Figure 1-Figure 12 As shown, the emulsion-type shell paint production equipment according to an embodiment of the present 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 lining plate 220, a sphere 230, a powder suction head 240, a powder suction box 250, a filter element 260 and an exhaust fan 270. The rotating outer barrel 210 is rotatably connected to the frame 100. The inner lining plate 220 is provided with a plurality of inner lining plates 220. One side of the inner lining plate 220 is rotatably connected to the inside of the rotating outer barrel 210. The plurality of inner lining plates 220 are arranged in an array on the inner wall of the rotating outer barrel 210. The frame 100 is located inside the rotating outer barrel 210 and is provided with a first limiting ring strip 110. One side of the inner lining plate 220 is connected to the first limiting ring strip 110. 10 sliding connection, the inner lining plate 220 rotates to the first limiting ring strip 110 on the upper inner side of the rotating outer barrel 210 and no longer limits the inner lining plate 220, a plurality of spheres 230 are provided, and the plurality of spheres 230 are placed inside the rotating outer barrel 210, one side of the powder suction head 240 is fixedly connected to the frame 100, and the other side of the powder suction head 240 extends to the inside of 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 provided on the other side of the powder suction box 250, and 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 the emulsion shell paint production equipment according to a specific embodiment of the present application is described below with reference to the accompanying drawings;

[0051] First, the shell is placed inside the barrel 211, which is also the inner side of the multiple lining plates 220, and the barrel cover 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, and the rotation of the barrel 211 drives the multiple lining plates 220 to rotate. The lining plates 220 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, and the sphere 230 performs ball milling on the shell;

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

[0053] Finally, the powder and particles diffuse inside the barrel body 211. Under the action of gravity, the particles are moved faster than the powder. The input end of the exhaust fan 270 draws air from the filter cartridge barrel 261. The filter cartridge barrel 261 draws air from the inside of the box body 251 through the filter cartridge 262. The air inside the box body 251 contains powder. At this time, the output end of the second motor 2632 drives the brush body 2631 to rotate to clean one side of the filter cartridge 262. The box body 251 draws air from the inside of the powder suction head 240. The powder suction head 240 draws the powder diffused inside the barrel body 211. Finally, the powder stays at the bottom of the box body 251 and is finally discharged through the discharge barrel 254.

[0054] Therefore, since the shells can be crushed while the powder produced by the crushing can be extracted into the powder suction box 250, the process of preparing shell powder is reduced and the efficiency of preparing shell powder can be improved.

[0055] In addition, the emulsion shell paint production equipment according to the embodiment of the present application also has the following additional technical features:

The rotating end of the rotating cleaning brush 263 cleans one side of the filter element 262, and the input end of the exhaust fan 270 is connected to the filter element barrel 261.

[0063] According to this application, if 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 box body 251 , and the brush body 2631 is drivingly 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, that is, crushed into small particles of shell particles, and then crushed into powder according to production needs. Therefore, two sets of equipment are needed, one is the coarse crushing equipment, and the other is the powder grinding equipment. Therefore, the shell particles inside the coarse crushing equipment need to be taken out and transported to the powder grinding equipment, which will increase the crushing time and reduce the efficiency of shell powder preparation.

[0065] According to this application, if Figure 8-Figure 10As shown, the grinding assembly 300 is also included, and the grinding assembly 300 includes a first transmission shaft 310, a second transmission shaft 320, a bracket 330, a hopper 340, an upper grinding block 350, a lower grinding block 360 and a blower 370. The hopper 340, the upper grinding block 350 and the lower grinding block 360 are each provided with a plurality of them.

During the ball milling process, the powder and small particles of the shells will pass through the inner lining plate 220 and enter the area between the inner lining plate 220 and the rotating outer barrel 210. At this time, the inner lining plate 220 is limited by the first limiting ring strip 110 and cannot rotate by itself. Therefore, the rotating outer barrel 210 will rotate with the inner lining plate 220 during the rotation process.
