Description

A powder making and drying equipment for preparing glass glaze

Technical Field

The invention relates to the technical field of glaze preparation, in particular to powder making and drying equipment for preparing glass glaze.

Background Art

Glazes are widely used in ceramic, glass and other product fields. In addition to improving the appearance, glazes also improve properties such as easy cleaning and anti-fouling. In addition, during the firing process of the products, some trace components in the glaze can also improve the hot-melt properties of the glass, making it easier to shape.

During the preparation stage, glazes generally go through the process of mixing, grinding and drying of various raw materials. During the grinding process, only a small amount of water is added to ensure that there is no dust floating during the grinding process. In order to ensure that the powder particle size of the glaze meets the use requirements, most of them are guaranteed by increasing the grinding time. Some particles that have been ground in place are not taken out in time. Repeated grinding generates a lot of heat and a lot of useless work, which not only wastes the power of the grinder, but also affects the processing efficiency of the device. The output speed of the glaze is limited. The ground glaze is heated and dried. During this process, some particles agglomerate and need to be filtered out by structures such as screens. When the screen is used to screen out the agglomerated glaze, a lot of dust is generated, and the working environment is harsh.

Summary of the invention

The object of the present invention is to provide a powder making and drying device for preparing glass glaze to solve the problems raised in the above background technology.

In order to solve the above technical problems, the present invention provides the following technical solutions:

A powder making and drying device for preparing glass glaze, the powder making and drying device comprises a grinder, a separation box, a dryer and an air separation unit. The grinder receives the crushed glaze ore delivered by the previous crusher and grinds it with water. The separation box is respectively connected to the inlet and outlet of the grinder and the inlet of the dryer. A material pump facing the separation box is arranged on the inlet pipeline of the separation box. Throttle valves are respectively arranged on the outflow pipeline of the separation box. The separation box has a fully enclosed structure. The separation box is connected to separate the material entering it into coarse material and fine material. The dryer is a screw structure. The dryer heats the material while extruding it. The air separation unit is connected to the outlet of the dryer.

The crusher crushes the raw ore used to make glaze into smaller particles with uniform relative particle size and then introduces them into the grinder to start the powder making and drying process of this device. The grinder adds a small amount of water to mix with the raw materials and grinds them. The raw materials are output in a slurry state. It is not easy to distinguish whether the grinding is in place by means of filters or the like at the discharge of the grinder. The setting of the screening structure affects the material output and flow, and further affects the overall efficiency of the device. This application uniformly transmits all the materials that have been ground once and diverts them at the separation box. The fine materials that have been ground perfectly are sent to the dryer through the separation box for drying and dehydration to become powder, while the slurry that has not been ground in place flows back to the grinder for further processing. After a repeated grinding cycle, the dryer heats and evaporates most of the moisture in the slurry, and the material is squeezed out of the dryer in a dry state. Most of the extruded glaze is powder, which may be transported and collected by wind after entering the air selection unit, while a small part of the glaze is in agglomerated state, which affects the quality of the powder when directly output as a finished product. The trace amount of agglomerated glaze in the air selection unit cannot be carried away and transferred by the wind, and the agglomerated glaze falls when it enters the air selection unit. It can be collected separately for manual powder making, or returned to the grinder through a pipeline for a repeated powder making and drying process. A material truck can be placed at the place where the air selection unit outputs the finished glaze, and transferred to the packaging and warehousing process.

The grinder includes a frame, a grinding assembly, a matching plate, and a hopper. The grinding assembly is installed on the upper end of the frame, and the matching plate is also installed on the frame and is located directly below the grinding assembly. The hopper is arranged at the bottom of the frame. The grinding assembly includes a rotary drive fixed to the frame, and a disc body is installed on the output end of the rotary drive. A plurality of feed pipes are arranged on the disc body. The upper ends of the feed pipes are gathered into an annular trough, and the lower ends of the feed pipes pass through the disc body and are connected to the lower surface of the disc body. There is a gap between the outer edge of the matching plate and the frame, and a feed trough is arranged in the frame, and the bottom surface of the feed trough has an opening facing the hopper.

The material to be ground is added into the trough from above, and the trough, discharge pipe and disc body rotate together. The material entering the trough falls through the discharge pipe and enters the grinding gap between the disc body and the matching disc to be plane ground. The water required for grinding, the coarse material returned from the separation box, and the material returned from the air selection unit all enter the trough and enter the grinding position through the discharge pipe. The ground material overflows from the edge into the gap between the matching disc and the edge of the frame and enters the discharge trough, and finally flows into the hopper. The hopper is connected to the material pump and is pressurized and injected into the separation box.

The grinding machine also includes a lifting drive, the connection between the matching disk and the frame is an up and down floating connection, the lifting drive is arranged at the connection between the matching disk and the frame, and the lifting drive controls the upward force of the matching disk.

The disc body rotates in place. If the mating disc is fixed, the grinding gap will be fixed, and the particle size of tiny particles in the produced grinding slurry will remain roughly unchanged. The present application adds a lifting drive to change the upward force of the mating disc, thereby adjusting the grinding gap and controlling the target particle size of the glaze particles in the slurry.

The separation box includes a first box body, a perforated plate, and a second box body. The first box body and the second box body clamp the perforated plate. The horizontal side of the first box body respectively opens a feed port and a coarse material port. The horizontal side of the second box body opens a fine material port. The fine material port and the coarse material port are located on the same side. The fine material port is connected to a dryer, and the coarse material port is connected to a grinder.

The material is pressurized and injected between the first box body and the orifice plate through the material pump. The material flows horizontally and there is pressure in the separation box. Most of the finer components in the slurry can pass through the orifice plate under the action of the pressure difference and enter between the orifice plate and the second box body, and then be discharged from the fine material port. Some coarse materials in the slurry that are not fully ground cannot pass through the orifice plate. Moreover, because the slurry flows horizontally, the movement of the coarse materials does not vertically hit the micropores on the orifice plate that can pass through. The coarse slurry will be horizontally washed away by the flowing slurry, and it is not easy to block the orifice plate. The pressure difference on both sides of the orifice plate can be adjusted by the throttle valves on the subsequent pipelines of the fine material port and the coarse material port, so that most of the slurry entering the separation box flows through the orifice plate as the flow to the next process.

The first box body is located below the second box body.

The first box body is at the bottom, that is, the direction in which the materials entering the separation box pass through the orifice plate is from bottom to top, and gravity can be further used to prevent coarse particles from blocking the micropores on the surface of the orifice plate.

The dryer includes a casing, a screw, a wet material inlet, an exhaust port, and a dry material outlet. A meshing screw is rotatably arranged inside the casing, the casing is tilted, a wet material inlet and an exhaust port are arranged at the upper end of the casing side wall, a dry material outlet is arranged at the lower end of the casing side wall, a heating structure is provided at the end of the screw, the wet material inlet is connected to a separation box, and the dry material outlet leads to an air selection unit.

The glaze that enters the screw meshing position is heated, and the water evaporates and is discharged from the exhaust port to preheat the newly entered wet glaze. A certain power setting can allow the glaze of a specific flow rate to be completely dried and crushed into powder after passing through the screw and discharged from the dry material outlet. A very small amount of agglomerated glaze is processed in the subsequent air separation unit.

There are three screws, which are distributed in the shape of a regular triangle in cross section, and the surface of one of the screws is a smooth rod.

The three screws for extrusion can increase the contact path length between the material and the screw, increase the drying time, and fully remove moisture for drying.

The air selection unit includes a fan, an ascending pipe, an inclined pipe, a separator, and a discharge valve. The separator is a cyclone separator. The upper side wall of the separator is connected to the upper end of the ascending pipe. The end of the ascending pipe away from the separator is bent downward to become a vertical section. The side wall of the vertical section of the ascending pipe is connected to the inclined pipe, and the inclined pipe is connected to the dryer. The air outlet of the fan leads to the lower end of the ascending pipe through a pipeline and the air outlet faces upward. Discharge valves are respectively arranged at the lower end of the separator and the lower end of the ascending pipe.

The dried glaze from the dryer flows into the middle of the riser through the inclined pipe. The airflow from bottom to top can carry the completely dry and finely broken glaze into the separator. The flow velocity of the glaze powder in the separator is greatly reduced and it falls and accumulates at the bottom of the separator. The agglomerated glaze in the inclined pipe cannot be lifted by the airflow and falls to the bottom of the riser. The air volume of the fan can be adjusted as needed so that the wind force in the riser can only blow the completely dry and finely broken powder. The discharge valve at the bottom of the separator is opened regularly to allow the finished glaze to enter the material cart, and then transferred and packaged for storage. The material at the bottom of the riser is taken out and returned to the grinder regularly.

The air selection unit also includes an air diffuser, which is arranged in the riser, perpendicular to the axis of the flow channel of the riser, and located between the inclined pipe and the end of the fan outlet pipe.

The air diffuser net allows the air flow to be cut when passing through it, fully filling all positions of the flow channel, allowing the falling glaze to fully contact the rising air flow. The agglomerated glaze also needs to pass through the air diffuser net when falling. When passing through the holes, the surrounding wind speed is greater, and there is a chance that some of the glaze will break the agglomeration state under the action of wind and be brought back to the separator by the air flow.

Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention first prepares the slurry of glaze components by grinding with water, does not distinguish the degree of grinding in the grinding stage, speeds up the grinding process, allows most of the materials to quickly go to the subsequent process, forms a horizontal flow in the separation box, does not allow the coarse slurry to be separated to block the orifice plate for the fine slurry to pass, the separation box is fully closed and operated under pressure, the pressure difference on both sides of the orifice plate is set as needed, the slurry of the fine material enters the subsequent drying process, and is crushed while drying, most of it becomes a powder state, is separated from a small amount of agglomerated glaze at the air selection unit, the powder glaze is collected and processed, and the agglomerated glaze enters the grinder to repeat the entire operation process of the device, and there is no blocking structure that affects the processing efficiency at all nodes, and the whole machine operates continuously to carry out powdering and drying of glass glaze.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A powder making and drying equipment for preparing glass glaze, the powder making and drying equipment comprises a grinder 1, a separation box 2, a dryer 3, and an air separation unit 4. The grinder 1 receives the glaze ore crushed material delivered by the previous crusher and grinds it with water. The separation box 2 is respectively connected to the inlet and outlet of the grinder 1 and the inlet of the dryer 3. A material pump 51 facing the separation box 2 is arranged on the inlet pipeline of the separation box 2. A throttle valve 52 is respectively arranged on the outflow pipeline of the separation box 2. The separation box 2 has a fully enclosed structure. The separation box 2 is connected to separate the material entering it into coarse material and fine material. The dryer 3 is a screw structure. The dryer 3 heats the material while extruding the material. The air separation unit 4 is connected to the outlet of the dryer 3.

As shown in Figure 1, the crusher crushes the raw ore used to make the glaze into smaller particles with relatively uniform particle size and then introduces them into the grinder 1 to start the powder making and drying process of the device. The grinder 1 adds a small amount of water to mix with the raw material and grinds it. The raw material becomes a slurry and is output backward. It is not easy to distinguish whether it is ground in place in the form of a filter screen at the discharge of the grinder 1. The setting of the screening structure affects the material output and flow, and further affects the overall efficiency of the device. This application uniformly transmits all the materials that have been ground once and diverts them at the separation box 2. The fine materials that have been ground perfectly pass through the separation box 2 to the dryer 3 for drying and dehydration to become powder, while the slurry that has not been ground in place flows back to the grinder 1. After a repeated grinding cycle, the dryer 3 heats and evaporates most of the moisture in the slurry, and the material is squeezed out of the dryer 3 in a dry state. Most of the extruded glaze is powder, which may be transported and collected by wind after entering the air selection unit 4, while a small part of the glaze is in a caked state, which affects the quality of the powder when directly output as a finished product. The trace amount of caked glaze in the air selection unit 4 cannot be carried away and transferred by the wind, and the caked glaze falls when entering the air selection unit 4, and can be collected separately for manual powder making, or returned to the grinder 1 through a pipeline for a repeated powder making and drying process. The material cart 6 can be placed at the place where the finished glaze is output from the air selection unit 4 to receive it and transfer it to the packaging and warehousing process.

The grinding machine 1 includes a frame 11, a grinding assembly 12, a matching plate 13, and a hopper 14. The grinding assembly 12 is installed on the upper end of the frame 11, and the matching plate 13 is also installed on the frame 11 and is located directly below the grinding assembly 12. The hopper 14 is arranged at the bottom of the frame 11. The grinding assembly 12 includes a rotary drive fixed to the frame 11, and a disc body 121 is installed at the output end of the rotary drive. A plurality of feed pipes 122 are arranged on the disc body 121. The upper ends of the feed pipes 122 are summarized into an annular trough, and the lower ends of the feed pipes 122 pass through the disc body 121 and are connected to the lower surface of the disc body 121. There is a gap between the outer edge of the matching plate 13 and the frame 11, and a feed trough 111 is arranged in the frame 11, and the bottom surface of the feed trough 111 is opened toward the hopper 14.

As shown in Figures 2 to 4, the material to be ground is added to the trough from above, and the trough, the discharge pipe 122 and the disc body 121 rotate together. The material entering the trough falls through the discharge pipe 122 and enters the grinding gap between the disc body 121 and the matching disc 13 to be plane-ground. The water required for grinding, the coarse material returned from the separation box 2, and the material returned from the air selection unit 4 all enter the trough and enter the grinding position through the discharge pipe 122. The ground material overflows from the edge into the gap between the matching disc 13 and the edge of the frame 11 and enters the drop trough 111, and finally flows into the hopper 14. The hopper 14 is connected to the material pump 51 and is pressurized and injected into the separation box 2.

The grinding machine 1 further comprises a lifting drive 15 . The connection between the matching disk 13 and the frame 11 is an up-and-down floating connection. The lifting drive 15 is arranged at the connection between the matching disk 13 and the frame 11 . The lifting drive 15 controls the upward force of the matching disk 13 .

The disc body 121 rotates in place. If the mating disc 13 is fixed, the grinding gap will be fixed and the particle size of the tiny particles in the produced grinding slurry will remain roughly unchanged. The present application adds a lifting drive 15 to change the upward force of the mating disc 13, thereby adjusting the grinding gap and controlling the target particle size of the glaze particles in the slurry.

The separation box 2 includes a first box body 21, a perforated plate 22, and a second box body 23. The first box body 21 and the second box body 23 clamp the perforated plate 22. A feed port 201 and a coarse material port 203 are respectively provided on the horizontal sides of the first box body 21. A fine material port 202 is provided on the horizontal side of the second box body 23. The fine material port 202 and the coarse material port 203 are located on the same side. The fine material port 202 is connected to the dryer 3, and the coarse material port 203 is connected to the grinder 1.

As shown in Figures 1, 5 and 6, the material is pressurized and injected between the first box body 21 and the orifice plate 22 by the material pump 51. The material flows horizontally and there is pressure in the separation box 2. Most of the finer components in the slurry can pass through the orifice plate 22 under the action of the pressure difference and enter between the orifice plate 22 and the second box body 23, and then be discharged from the fine material port 202. Some coarse materials in the slurry that are not fully ground cannot pass through the orifice plate 22. Moreover, because the slurry flows horizontally, the movement of the coarse materials is not vertically colliding with the micropores on the orifice plate 22 that can pass through. The coarse slurry will be horizontally washed away by the flowing slurry, and it is not easy to block the orifice plate 22. The throttle valve 52 on the subsequent pipelines of the fine material port 202 and the coarse material port 203 can be used to adjust the pressure difference on both sides of the orifice plate 22, so that most of the slurry entering the separation box 2 flows through the orifice plate 22 as the flow to the next process.

The first box body 21 is located below the second box body 23 .

As shown in FIG. 5 , the first box body 21 is at the bottom, that is, the material entering the separation box 2 passes through the orifice plate 22 from bottom to top, and gravity can be further used to prevent coarse particles from blocking the micropores on the surface of the orifice plate 22 .

The dryer 3 includes a casing, a screw 31, a wet material inlet 32, an exhaust port 33, and a dry material outlet 34. The screw 31 is rotatably arranged in meshing engagement in the casing, the casing is tilted, the wet material inlet 32 and the exhaust port 33 are arranged at the upper end of the casing side wall, the dry material outlet 34 is arranged at the lower end of the casing side wall, the end of the screw 31 is provided with a heating structure, the wet material inlet 32 is connected to the separation box 2, and the dry material outlet 34 leads to the air selection unit 4.

As shown in FIG7 , the glaze entering the meshing position of the screw 31 is heated, and the water evaporates and is discharged from the exhaust port 33 to preheat the newly entered wet glaze. A certain power setting can be used to allow the glaze of a specific flow rate to be completely dried and crushed into powder after passing through the screw 31 and discharged from the dry material outlet 34. A very small amount of agglomerated glaze is processed in the subsequent air selection unit 4.

There are three screw rods 31 , and the three screw rods 31 are distributed in a regular triangle shape in cross section, and the surface of one of the screw rods 31 is a smooth rod.

The three screws for extrusion can increase the contact path length between the material and the screw 31, increase the drying time, and fully remove moisture for drying.

The air selection unit 4 includes a fan 41, an ascending pipe 42, an inclined pipe 43, a separator 44, and a discharge valve 45. The separator 44 is a cyclone separator. The upper side wall of the separator 44 is connected to the upper end of the ascending pipe 42. One end of the ascending pipe 42 away from the separator 44 is bent downward to become a vertical section. The side wall of the vertical section of the ascending pipe 42 is connected to the inclined pipe 43, and the inclined pipe 43 is connected to the dryer 3. The air outlet of the fan 41 is connected to the lower end of the ascending pipe 42 through a pipeline and the air outlet faces upward. The lower end of the separator 44 and the lower end of the ascending pipe 42 are respectively provided with discharge valves 45.

As shown in Figure 8, the dried glaze from the dryer 3 flows into the middle of the riser 42 through the inclined pipe 43. The airflow from bottom to top can carry the completely dry and finely broken glaze into the separator 44. The flow velocity of the glaze powder in the separator 44 is greatly reduced and the glaze powder falls and accumulates at the bottom of the separator 44. The agglomerated glaze body in the inclined pipe 43 cannot be lifted by the airflow and falls to the bottom of the riser 42. The air volume of the fan 41 can be adjusted as needed so that the wind force in the riser 42 can only blow the completely dry and finely broken powder. The discharge valve 45 at the bottom of the separator 44 is opened regularly to allow the finished glaze to enter the material cart 6, and then transferred and packaged for storage. The material at the bottom of the riser 42 is taken out and returned to the grinder regularly.

The air selection unit 4 further includes an air diffuser 46 , which is disposed in the riser 42 . The air diffuser 46 is perpendicular to the flow channel axis of the riser 42 , and is located between the inclined tube 43 and the end of the air outlet pipe of the fan 41 .

As shown in FIGS. 8 and 9 , the air diffuser 46 allows the airflow to be cut when passing through it, fully filling all positions of the flow channel, allowing the falling glaze to fully contact the rising airflow, and the agglomerated glaze also needs to pass through the air diffuser 46 when falling. When passing through the holes, the surrounding wind speed is greater, and there is a chance that part of the glaze can be broken out of the agglomerate state under the action of wind and be brought back to the separator 44 by the airflow.
