Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of porcelain enamel processing, and particularly relates to an acid-resistant porcelain enamel original slurry non-contact pretreatment device and a control method thereof. BACKGROUND

[0002] In the processing of porcelain enamel, the original slurry powder needs to be pretreated to prevent uneven mixing of internal substances, which will cause the stability of the finished porcelain enamel to decrease after sintering and setting.

[0003] After searching, a patent document with the patent number CN115636694A and the publication date of 20230124, named a nano self-cleaning ceramic glaze and a preparation method thereof, is found. The document includes the following steps: clay, sodium feldspar, quartz sand, glass powder, borax, nano zinc oxide, nano titanium dioxide and water are mixed and ball milled to a medium particle size D 50≦60um to obtain a premixed glaze slurry, and then stirred and sand milled to a medium particle size D 50≦0.1um to obtain a base glaze slurry. The above example maximizes the photocatalytic and antibacterial effects of anatase titanium dioxide, and the low-temperature calcined glaze surface is relatively smooth and easy to clean.

[0004] However, the above example still has the following defects: in the preparation of porcelain enamel, in order to improve the acid resistance of the porcelain enamel, an acid-proof layer needs to be coated on the surface of the porcelain enamel after it is made. However, the acid-proof layer is prone to fall off after being exposed to air for a long time or being rubbed with the outside world, which reduces the acid-proof effect. Moreover, after the original slurry powder is ground, the caked material cannot be crushed, which reduces the grinding effect. SUMMARY

[0016] A control method for a non-contact pretreatment device for acid-resistant porcelain glaze slurry, the control method comprising:

[0017] Pour the raw slurry powder and alkaline oxide solution into the grinding base at a ratio of 10:1;

[0018] Start the first motor, which drives the first and second rotating rods to rotate, thereby causing the third rotating rod and the grinding ball to rotate;

[0019] Start the electric push rod, which drives the grinding ball down into the grinding base. The grinding strip slides against the inner wall of the grinding base to crush and grind the raw slurry powder block in the grinding base. During the crushing and grinding process, the raw slurry powder is mixed with the alkaline oxide solution to obtain a semi-finished raw slurry powder.

[0020] After grinding and pulverizing, the semi-finished raw slurry powder enters the sintering unit cavity through the discharge hole;

[0021] The temperature inside the sintering unit cavity is heated to 600℃±20℃ to remove excess moisture from the fused semi-finished raw slurry powder.

[0022] After heating for an hour, heating is stopped, the preheating and sintering process is completed, and the finished raw slurry powder is obtained;

[0023] The finished raw slurry is discharged from the sintering unit cavity, and the pretreatment work is completed.

[0024] The beneficial effects of this invention are:

[0025] 1. An alkaline oxide solution is added simultaneously with the grinding of the raw slurry powder. After grinding, preheating and sintering in a sintering unit ensures the slurry powder and alkaline oxide are fused, preventing the easy detachment issue when directly coating the acid-resistant layer. Furthermore, no manual handling or conveying is required during the pretreatment process, achieving contactless operation. Meanwhile, during the grinding process, the grinding bars not only pulverize the raw slurry powder but also use their edges to scoop up the powder from the inner wall of the grinding base, then blow it into the various discharge holes through the first high-pressure air hole. This ensures that the raw slurry powder entering the sintering unit is in a fine powder form, guaranteeing the grinding effect and preventing powder residue from remaining in the grinding base.

[0026] 2. A hemispherical splash guard is installed above the grinding balls. While the grinding balls are grinding in the grinding base, the splash guard and the inner wall of the guide tube prevent the raw slurry powder from splashing outside the guide tube. The raw slurry powder on the inner wall of the splash guard will slide back into the grinding base through the guide grooves. At the same time, the sliding contact between the splash guard and the inner wall of the guide tube prevents raw slurry powder from remaining on the inner wall of the guide tube, reducing material waste and improving the ease of cleaning the device.

[0027] 3. Preheating the raw slurry powder in the sintering chamber before formal sintering not only shortens the formal sintering time but also removes moisture from the raw slurry powder. Simultaneously, dividing the sintering chamber into several independent sintering chambers for individual heating increases the contact area between the raw slurry powder and the heat source, resulting in more thorough heating, shorter heating time, and improved preheating efficiency.

[0028] 4. An alkaline oxide solution is added while the raw slurry powder is being crushed and ground. After crushing, preheating and sintering are performed in a sintering unit to fuse the raw slurry powder and alkaline oxide, avoiding the problem of easy detachment when directly coating the acid-resistant layer. Furthermore, no manual handling or conveying is required during the pretreatment process, achieving contactless operation.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention provides a non-contact pretreatment device for acid-resistant porcelain glaze slurry, including a base 100. For example,... Figure 1 As shown, a top plate 120 is provided above the base 100, and a side plate 110 is installed at one edge of the top of the base 100, with the top of the side plate 110 installed at the bottom of the top plate 120.

[0042] The top plate 120 is provided with an upper ball mill unit 200 at its bottom.

[0043] A lower ball milling unit 300 is located directly below the upper ball milling unit 200, and the bottom of the upper ball milling unit 200 extends movably into the lower ball milling unit 300. During crushing, the upper ball milling unit 200 and the inner wall of the lower ball milling unit 300 slide and rub against each other, thereby grinding and crushing the raw slurry powder.

[0044] A sintering unit 400 is installed on the base 100, and the bottom of the lower ball milling unit 300 extends into the cavity of the sintering unit 400, with the cavity of the lower ball milling unit 300 communicating with the cavity of the sintering unit 400.

[0045] A collection unit 500 is provided on one side of the sintering unit 400, and the output end of the sintering unit 400 is connected to the input end of the main body of the collection unit 500. The sintering unit 400 is used to sinter the crushed raw slurry powder.

[0046] The upper ball mill unit 200 includes an electric actuator 201. For example, as... Figure 2 and Figure 3As shown, the top of the electric push rod 201 is mounted on the bottom of the top plate 120. A grinding ball rotating mechanism is mounted on the bottom of the electric push rod 201. The grinding ball rotating mechanism includes a rotating rod mounting plate 202, a first motor 210, a first sealed bearing 220, and two sets of pulleys 230. The rotating rod mounting plate 202 is mounted on the bottom of the electric push rod 201. The first motor 210 and the first sealed bearing 220 are both located on the rotating rod mounting plate 202 and are symmetrically arranged on both sides of the electric push rod 201. The output end of the first motor 210 extends below the rotating rod mounting plate 202 and is connected to a first rotating rod 211. An air pump 221 is provided on the top of the first sealed bearing 220. The bottom of the first sealed bearing 220 extends directly below the rotating rod mounting plate 202 and is rotatably connected to a second rotating rod 222. The top of the second rotating rod 222 is connected to the output end of the air pump 221 through the first sealed bearing 220. The two sets of pulleys 230 are respectively sleeved on the first rotating rod 211 and the second rotating rod 222, and the two sets of pulleys 230 are connected by a belt 231.

[0047] For example, the bottom of the second rotating rod 222 is connected to a third rotating rod 240, and the bottom of the third rotating rod 240 is connected to a grinding mechanism 250. A splash guard 270 is provided directly above the grinding mechanism 250, and a vertical rod 260 is mounted on the splash guard 270. The top of the vertical rod 260 is mounted on the bottom of the rotating rod mounting plate 202. The splash guard 270 has a hemispherical structure, and a second sealed bearing is provided between the inner wall of the splash guard 270 and the outer wall of the third rotating rod 240. Several sets of guide grooves 271 are distributed in a circular array on the inner wall of the splash guard 270.

[0048] The grinding mechanism 250 includes grinding balls 251. For example, as shown... Figure 4 and Figure 5 As shown, the grinding ball 251 has a spherical structure, and an air inlet 254 is provided at the top of the grinding ball 251. The top of the air inlet 254 is connected to the bottom of the third rotating rod 240. The bottom of the air inlet 254 extends into the grinding ball 251 and is connected to an inner balloon 255, which is also spherical. Several sets of second high-pressure air holes 256 are arranged in a ring array on the outer wall of the inner balloon 255. Several sets of grinding strips 252 are arranged in a ring array on the outer wall of the grinding ball 251. A set of first high-pressure air holes 253 is provided between each pair of adjacent sets of grinding strips 252. The number of first high-pressure air holes 253 is the same as the number of second high-pressure air holes 256, and each set of first high-pressure air holes 253 is connected to a corresponding set of second high-pressure air holes 256.

[0049] The lower ball milling unit 300 includes a conduit 310. For example, as shown... Figure 6As shown, the conduit 310 is located at the top of the sintering unit 400 body, and the bottom of the conduit 310 extends into the cavity of the sintering unit 400 body and is connected to a grinding base 320, which has a hemispherical structure. The grinding ball 251 is located directly above the conduit 310, and the grinding ball 251 extends movably into the grinding base 320 through the conduit 310. The outer walls of several sets of grinding strips 252 are slidably attached to the inner wall of the grinding base 320. Several sets of discharge holes 330 are evenly distributed on the grinding base 320, and the cavity of the grinding base 320 is connected to the cavity of the sintering unit 400 through each set of discharge holes 330.

[0050] First, the raw slurry powder and alkaline oxide solution are poured into the lower ball mill unit 300 at a ratio of 10:1. Then, the first motor 210 is started, which drives the first rotating rod 211 and the second rotating rod 222 to rotate, thereby causing the third rotating rod 240 and the grinding balls 251 to rotate. Then, the electric push rod 201 is started, which drives the grinding balls 251 to descend into the grinding base 320. The grinding balls 252 and the inner wall of the grinding base 320 are used to crush and grind the lumps in the raw slurry powder. After grinding, the raw slurry powder is fused with the alkaline oxide solution. The fused raw slurry powder enters the cavity of the sintering unit 400 through the discharge holes 330 for sintering.

[0051] The sintering unit 400 includes a sintering cylinder 410. For example, as shown... Figure 7 As shown, a sintering chamber 411 is formed inside the sintering cylinder 410. A collection chamber 412 is provided on the side of the sintering chamber 411 near the collection unit 500. A vacuum pump 440 is connected to the side wall of the collection chamber 412, and the output end of the vacuum pump 440 extends to the outside of the collection chamber 412 and is connected to a discharge hose 450. Several sets of partition plates 420 are evenly distributed vertically inside the sintering chamber 411, dividing the sintering chamber 411 into several independent sintering chambers. The grinding base 320 is connected to the cavity of each independent sintering chamber. The partition plates 420 are inclined, and the height of the side near the collection chamber 412 is lower than the height of the other side. An electric butterfly valve 430 connects the collection chamber 412 to each independent sintering chamber. An electromagnetic heater 460 is installed on the outer wall of the sintering cylinder 410, and the output end of the electromagnetic heater 460 is connected to each independent sintering chamber.

[0052] After being crushed and ground, the raw slurry powder in the grinding base 320 enters different independent sintering chambers through discharge holes 330 of different heights. Then, the electromagnetic heater 460 is activated to heat the temperature of each independent sintering chamber to 600℃±20℃, removing excess moisture from the fused raw slurry powder and ensuring thorough fusion of the raw slurry powder and alkaline oxides. The heating time is 0.5-2 hours (1 hour is a preferred embodiment). After heating, the raw slurry powder in each independent sintering chamber is discharged into the collection chamber 412 using each group of electric butterfly valves 430. Then, the vacuum pump 440 is activated to distribute the raw slurry to the collection unit 500.

[0053] The collection unit 500 includes a collection bin 510. For example, as shown... Figure 8 As shown, the collection box 510 is located on the base 100, and the input end of the collection box 510 is connected to the end of the discharge hose 450 away from the vacuum pump 440. Two sets of box side rods 520 are symmetrically hinged at both ends of the collection box 510. A motor mounting plate 530 is provided on one side of the collection box 510, and a second motor 540 is mounted on the motor mounting plate 530. A first swing rod 550 is drivenly connected to the output end of the second motor 540, and a second swing rod 560 is hinged to the other end of the first swing rod 550. The other end of the second swing rod 560 is hinged to the outer edge of one side of the collection box 510.

[0054] The second motor 540 is started, which drives the first swing rod 550 to move in a circular motion around the output end of the second motor 540 as the central axis. Then, the first swing rod 550 drives the second swing rod 560 to swing, thereby causing the collection box 510 to swing back and forth. This allows the raw slurry powder entering the collection box 510 to be evenly dispersed, which not only avoids the raw slurry powder from clumping but also shortens the cooling time of the raw slurry powder, thereby improving the efficiency of the pretreatment work.

[0055] This embodiment has the following beneficial effects:

[0056] 1. An alkaline oxide solution is added simultaneously with the grinding of the raw slurry powder. After grinding, preheating and sintering are performed in the sintering unit 400 to fuse the raw slurry powder and alkaline oxide, avoiding the problem of easy detachment when directly coating the acid-resistant layer. Furthermore, no manual handling or conveying is required during the pretreatment process, achieving contactless operation. Meanwhile, during the grinding process, the grinding strips 252 not only pulverize the raw slurry powder but also use the edges of the grinding strips 252 to scoop up the raw slurry powder from the inner wall of the grinding base 320, then blown into the various discharge holes 330 through the first high-pressure air hole 253. This ensures that the raw slurry powder entering the sintering unit 400 is in fine powder form, guaranteeing the grinding effect and preventing powder residue from remaining in the grinding base 320.

[0057] 2. A hemispherical splash guard 270 is installed above the grinding ball 251. While the grinding ball 251 enters the grinding base 320 for grinding, the splash guard 270 and the inner wall of the guide tube 310 prevent raw slurry powder from splashing onto the outside of the guide tube 310. Furthermore, the raw slurry powder on the inner wall of the splash guard 270 slides back into the grinding base 320 through the guide grooves 271. Simultaneously, the sliding contact between the splash guard 270 and the inner wall of the guide tube 310 prevents raw slurry powder from remaining on the inner wall of the guide tube 310, reducing material waste and improving the ease of cleaning the device.

[0058] 3. Preheating the raw slurry powder in the sintering chamber 411 before formal sintering not only shortens the formal sintering time but also removes moisture from the raw slurry powder. Simultaneously, dividing the sintering chamber 411 into several independent sintering chambers for individual heating expands the contact area between the raw slurry powder and the heat source, resulting in more thorough heating, shorter heating time, and improved preheating efficiency.

[0059] 4. Start the second motor 540. The second motor 540 drives the first swing rod 550 to move in a circular motion around the output end of the second motor 540 as the central axis. Then, the first swing rod 550 drives the second swing rod 560 to swing, thereby causing the collection box 510 to swing back and forth. This allows the raw slurry powder entering the collection box 510 to be evenly dispersed, which not only avoids the agglomeration of the raw slurry powder, but also shortens the cooling time of the raw slurry powder, thereby improving the efficiency of the pretreatment work.

[0060] Based on the aforementioned non-contact pretreatment device for acid-resistant porcelain glaze slurry, this invention also proposes a control method for the pretreatment device. For example, the control method includes:

[0061] Pour the raw slurry powder and alkaline oxide solution into the grinding base at a ratio of 10:1;

[0062] Start the first motor, which drives the first and second rotating rods to rotate, thereby causing the third rotating rod and the grinding ball to rotate;

[0063] Start the electric push rod, which drives the grinding ball down into the grinding base. The grinding strip slides against the inner wall of the grinding base to crush and grind the raw slurry powder block in the grinding base. During the crushing and grinding process, the raw slurry powder is mixed with the alkaline oxide solution to obtain a semi-finished raw slurry powder.

[0064] After grinding and pulverizing, the semi-finished raw slurry powder enters each group of independent sintering chambers through the discharge hole;

[0065] Start the electromagnetic heater to heat the temperature of each group of independent sintering chambers to 600℃±20℃ to remove excess moisture from the fused semi-finished raw slurry powder.

[0066] After heating for 1 hour, the electromagnetic heater is turned off, and the preheating and sintering process is completed, yielding the finished raw slurry powder.

[0067] Start each group of electric butterfly valves to transport all the finished raw slurry powder in each group's independent sintering chamber to the collection chamber;

[0068] Start the vacuum pump to transport the finished raw pulp powder in the collection chamber to the collection box;

[0069] Start the second motor, which drives the first and second swing rods to swing at a constant speed, and makes the collection box swing at a constant speed.

[0070] After all the finished raw pulp powder has been delivered, the pretreatment work is completed.

[0071] While the raw slurry powder is being crushed and ground, an alkaline oxide solution is added. After crushing, a sintering unit is used for preheating and sintering to fuse the raw slurry powder and the alkaline oxide, avoiding the problem of easy peeling when directly coating the acid-resistant layer. Furthermore, no manual handling or conveying is required during the pretreatment process, achieving contactless operation.

[0072] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
