Description

Technical Field

[0002] Water-based coatings used in casting can reduce the surface roughness of castings and prevent sand sticking defects in castings. Water-based coatings can enhance the surface strength and stability of sand molds, improve thermochemical stability, and promote surface alloying of castings. Grinding of water-based coatings used in castings is to improve the physical properties of the coatings, enhance the surface quality of the coatings, adapt to casting process requirements, and improve the quality of castings. These advantages make grinding an indispensable part of casting coating production.

[0003] However, the current water-based paint for casting is directly added to the inside of the grinding barrel during grinding, and the paint is ground by the shear force and impact force generated by the rotation of the grinding disc and the grinding ball.

If the barrel wall is not cooled, the paint will change color due to heat. This discoloration will cause the coating color to be uneven or inconsistent with the expected color, thereby affecting the appearance quality of the coating and having an adverse effect on the stability of the water-based paint, such as causing certain components in the paint to decompose or chemically react, thereby affecting the overall performance of the paint; when cleaning the grinding barrel, the barrel body is separated from the machine body, and the barrel body is horizontally slid for cleaning, and the barrel body is difficult to tilt, and it is difficult to discharge sewage during cleaning.

The ball mill The body 1 is connected to the grinding barrel 201 through a flange 202. A motor 203 is installed inside the ball mill body 1. The output end of the motor 203 is connected to a stirring shaft 204 that runs through the grinding barrel 201 through a coupling. A plurality of grinding plates 205 with a disc-shaped structure are equidistantly installed on the stirring shaft 204. The moving mechanism 4 includes two groups of support frames 401. The bottom of the grinding barrel 201 is relatively fixedly connected to the two groups of support frames 401. The bottoms of the four support frames 401 are rotatably connected to rollers 405. Two slides 402 are slidably connected to the ball mill body 1. The two groups of rollers 405 are rollingly connected to the two slides 402. The slides 402 are located on the support frames 401.

When grinding the water-based material, the water-based material to be ground is added from the feed pipe 304, and the motor 203 is started to realize that the stirring shaft 204 drives the grinding plate 205 to rotate. The grinding barrel 201 is provided with grinding balls. When the grinding plate 205 rotates, the grinding balls are driven to rotate inside the grinding barrel 201.

The qualified water-based paint passes through the filter screen 609 from the discharge port 603 and is finally discharged from the discharge pipe 610. The unqualified water-based paint is ground again inside the grinding barrel 201. During grinding, the high-speed collision of the grinding balls with the inner wall of the grinding barrel 201 generates more heat. In order not to affect the performance of the water-based paint, the grinding barrel 201 needs to be cooled. During cooling, The water inlet pipe 303 is connected to the coolant or water. The coolant enters the water inlet shell 302 and then is discharged from the two sets of water leaks 307. Finally, the water is divided into two parts and discharged from the two guide shells 308.

If it is necessary to move it significantly, the connecting frame 403 can be pulled to realize the rolling of the pulley 404 on the ground, and the slide 402 slides on the ball mill body 1. When cleaning, the rotating shaft 507 can be moved to the top of the clamping plate 707, and the screw rod 704 is rotated to realize the movement of the push block 703 on the slide rail 702. Further, the push block 703 lifts the push rod 705, and the walking wheel 706 can reduce the friction of the push block 703, which is more labor-saving.

[0039] Specifically, Figure 2 ,picture, Figure 3 , Figure 7 , Figure 8 and Fig. 9As shown, the grinding barrel 201 is provided with a filter mechanism 6, and the filter mechanism 6 includes a discharge port 603. The end of the grinding barrel 201 is provided with a discharge port 603. The side of the grinding barrel 201 is connected to a shell 601 corresponding to the discharge port 603.

In order to prevent the filter screen 609 from being blocked by unqualified water-based paint, The filter screen 609 rotates during grinding. In order to realize the rotation of the filter screen 609, a first gear 602 is installed at the end of the stirring shaft 204. When the stirring shaft 204 rotates, it drives the first gear 602 to rotate. Since the first gear 602 is vertically meshed with the second gear 607, the rotation of the first gear 602 drives the second gear 607 to rotate horizontally.

[0040] A grinding process of a water-based coating grinding device for casting, comprising the following steps:

[0041] S1: firstly, add the water-based paint into the interior of the grinding mechanism 2 for grinding, and during grinding, add coolant or water into the interior of the cooling mechanism 3 to cool the grinding mechanism 2, and the cooled water falls into the interior of the water receiving mechanism 5 for recycling;

[0042] S2: The paint that meets the requirements during grinding is filtered and discharged from the filtering mechanism 6, and the unqualified paint is ground again inside the grinding mechanism 2. During grinding, the grinding mechanism 2 drives the filtering mechanism 6 to rotate to avoid clogging of the filtering mechanism 6 and ensure the feeding speed;

[0043] S3: After grinding, the grinding mechanism 2 is separated from the ball mill body 1, and the grinding mechanism 2 is slid out by the moving mechanism 4. Further, one end of the grinding mechanism 2 is lifted by the lifting mechanism 7, and the sewage during cleaning inside the grinding mechanism 2 is poured out.

[0044] When the present invention is in use, first, when grinding the water-based material, the water-based material to be ground is added from the feed pipe 304, the motor 203 is started to realize that the stirring shaft 204 drives the grinding plate 205 to rotate, and the grinding barrel 201 is provided with grinding balls. When the grinding plate 205 rotates, the grinding balls are driven to rotate inside the grinding barrel 201, and the water-based paint is ground by the friction, impact and shear force of the grinding plate 205 and the grinding balls. The qualified water-based paint passes through the filter screen 609 from the discharge port 603 and is finally discharged from the discharge pipe 610. The unqualified water-based paint is ground again inside the grinding barrel 201. During grinding, due to the high-speed collision of the grinding balls with the inner wall of the grinding barrel 201, more heat is generated. In order not to affect the performance of the water-based paint, the grinding barrel 201 needs to be cooled. During cooling, the water inlet pipe 303 is connected to the coolant or water. After the cooling material enters the inside of the water inlet shell 302 The water is discharged from two groups of water leakage ports 307, and finally the water is divided into two parts and discharged from two guide shells 308. The cooled fluid flows to the outside of the grinding barrel 201, so as to realize cooling of the grinding barrel 201, avoid accidents caused by excessive internal temperature and pressure increase, and ensure that the internal coating of the grinding barrel 201 will not be affected by temperature and cause property changes. The wavy buffer plate 305 increases the heat absorption range, which is convenient for quickly absorbing the heat on the grinding barrel 201. On the other hand, it reduces the flow rate of the cooling water, and cools down better. The water after absorbing heat flows to the inside of the water receiving bucket 502, and the water dripping from the cross section of the grinding barrel 201 enters the inside of the guide plate 504, and finally flows from the guide plate 504 to the inside of the water receiving bucket 502 for collection. The support frame 401 is on the slide 402, and the slide 402 realizes the support of the support frame 401. When disassembling the grinding barrel 201, the grinding barrel 201 can be slid out by sliding the support frame 401 on the slide 402;

[0045] Then, when grinding the water-based paint, unqualified water-based paint cannot pass through the filter screen 609, and qualified water-based paint passes through the filter screen 609 and is discharged from the discharge pipe 610. In order to prevent the filter screen 609 from being blocked by unqualified water-based paint, the filter screen 609 needs to be rotated during grinding. In order to realize the rotation of the filter screen 609, a first gear 602 is installed at the end of the stirring shaft 204. When the stirring shaft 204 rotates, it drives the first gear 602 to rotate. Since the first gear 602 is vertically meshed with the second gear 607, the rotation of the first gear 602 drives the second gear 607 to rotate horizontally. After the rotation of the second gear 607, it drives the rotating rod 605 inside the connecting pipe 606 to rotate, and finally the clamping ring 608 drives the filter screen 609 to rotate, which ensures that the filter screen 609 located at the discharge port 603 is The net 609 is rotating all the time, so that unqualified water-based paint can be automatically scraped off to avoid blockage affecting the feeding speed. When the filter 609 needs to be replaced, the sealing cover 604 is disassembled, the bolts on the connecting pipe 606 are loosened, the rotating rod 605 is retracted to the inside of the connecting pipe 606, and the clamping ring 608 is taken out from the inside of the housing 601. At this time, the plug rod 611 is separated from the socket 612, and the filter 609 can be taken out. A new filter 609 is placed inside the housing 601, the sealing cover 604 is tightened, and the plug rod 611 is inserted into the corresponding socket 612. The plug rod 611 can limit the radial position of the filter 609 to ensure that the filter 609 can rotate, the second gear 607 is meshed with the first gear 602, and the bolts on the outside of the connecting pipe 606 are tightened.

[0046] Finally, when cleaning the inside of the grinding barrel 201, the flange 202 is separated from the ball mill body 1, and the support frame 401 is pulled to realize the rolling of the roller 405 on the slide 402, which is beneficial to the movement of the grinding barrel 201. If it needs to be moved significantly, the connecting frame 403 can be pulled to realize the rolling of the pulley 404 on the ground, and the slide 402 slides on the ball mill body 1. When cleaning, the rotating shaft 507 can be moved to the top of the card plate 707, and the screw rod 704 is rotated to realize the movement of the push block 703 on the slide rail 702. Further, the push block 703 lifts the push rod 705, and the walking wheel 706 can reduce the friction of the push block 703, which is more labor-saving. After the push rod 705 rises, the card plate 707 pushes the rotating shaft 507. At this time, the grinding barrel 201 is tilted, which is beneficial to the discharge of sewage during cleaning.
