Description

Technical Field

[0002] Ceramic slurry drying spray towers are key equipment in ceramic production. With the rapid development of the ceramic industry, the requirements for production efficiency and product quality are constantly increasing. Traditional drying methods are no longer sufficient to meet these demands. Spray tower drying technology has emerged to address this need. It disperses ceramic slurry into fine droplets through an atomizer, allowing them to fully contact with hot air and achieve rapid and uniform drying. This equipment offers high drying efficiency, produces products with uniform particle size and good flowability, and is widely used in fields such as ceramic powder preparation.

[0003] After completing the heat exchange between hot air and ceramic slurry, existing spray towers usually deliver the air directly outside the equipment. However, the temperature of this air is still much higher than room temperature, and directly discharging it outside the equipment will result in a waste of thermal energy. Utility Model Content

[0021] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] The embodiments provided by this utility model are as follows: Figures 1-3 As shown, an energy-saving spray tower includes a main body 10, a heating furnace 20, a vacuum cleaner 30, a bag filter 40, and an exhaust fan 50. The top of the heating furnace 20 is connected to the side wall of the vacuum cleaner 30 via a first air supply pipe 60. The top of the vacuum cleaner 30 is connected to the top of the main body 10 via a second air supply pipe 70. A third air supply pipe 80 is fixedly connected to the top of the bag filter 40. The third air supply pipe 80 passes through the side wall of the main body 10 and extends into the interior of the main body 10. The side wall of the bag filter 40 is connected to the suction end of the exhaust fan 50 via a suction pipe 90. An exhaust pipe 100 and a return pipe 110 are fixedly connected to the exhaust end. The end of the return pipe 110 away from the exhaust fan 50 is fixedly connected to the side wall of the heating furnace 20. Multiple horizontal drive devices 120 are fixedly arranged around the side wall of the main body 10. A support column 130 is provided on the horizontal drive device 120. A first drive motor 140 is fixedly arranged on the support column 130. A spray gun 150 with an upward nozzle is fixedly connected to the output end of the first drive motor 140. The spray gun 150 passes through the side wall of the main body 10 and extends into the interior of the main body 10. A discharge port 160 is opened at the bottom of the main body 10.

[0023] During use, the operator starts the spray tower device, and the heating furnace 20 heats the air inside the furnace. The hot air that reaches the required temperature enters the vacuum cleaner 30 through the first air supply pipe 60. The vacuum cleaner 30 removes particulate impurities from the hot air. The dust-removed hot air then enters the main body 10 through the second air supply pipe 70. At this time, the spray gun 150 sprays the internal ceramic slurry out along the nozzle. The ceramic slurry comes into rapid contact with the hot air for heat exchange. The hot air quickly evaporates the water vapor in the ceramic slurry, causing the ceramic slurry to dry rapidly into granules. The finished granules are then dried by gravity. The hot air flows out through the discharge port 160. After completing the heat exchange, the hot air enters the bag filter 40 through the third air supply pipe 80. Due to the air flow, small finished product particles inevitably enter the bag filter 40 with the gas flow. The bag filter 40 can adsorb and filter the finished product particles in the air. The dust-removed air enters the exhaust fan 50 through the suction pipe 90. Then, part of the air enters the heating furnace 20 again through the return air pipe 110 for heating and recycling, saving energy. Part of the air is discharged outside the device through the exhaust pipe 100.

[0024] Since the main body 10, heating furnace 20, vacuum cleaner 30, bag dust collector 40 and exhaust fan 50 are connected as a whole through pipes, the operation of exhaust fan 50 creates negative pressure in the entire device, ensuring that air can flow freely between the components.

[0025] To ensure that the ceramic slurry can fully contact the hot air, the nozzle of the spray gun 150 is set upward. However, this will cause some ceramic slurry and finished particles to fall into the spray gun 150 or the edge of the nozzle, causing accumulation or even blockage. Therefore, when the spray gun 150 is working, the horizontal drive device 120 drives the support column 130 to move horizontally, which in turn drives the spray gun 150 to move horizontally. During this process, some of the accumulated material at the nozzle is shaken off. After the spray gun 150 has been working for a certain period of time, the first drive motor 140 drives the spray gun 150 to rotate. During the rotation of the spray gun 150, the remaining accumulated material at the nozzle is thrown out, ensuring that the spray gun 150 can smoothly spray out the ceramic slurry.

[0026] Preferably, the horizontal drive device 120 includes a base 121, which is fixedly connected to the side wall of the main body 10. A second drive motor 122 with its output end facing the main body 10 is fixedly mounted on the base 121. A lead screw 123 is fixedly connected to the output end of the second drive motor 122. The end of the lead screw 123 away from the second drive motor 122 is rotatably connected to the base 121. The lead screw 123 is threadedly connected to the support column 130.

[0027] Preferably, the spray gun 150 includes a nozzle 151 and a gun body 152. The gun body 152 is fixedly connected to the output end of the first drive motor 140. The gun body 152 passes through the side wall of the main body 10 and extends into the interior of the main body 10. A material inlet 153 is provided on the gun body 152. The material inlet 153 is located on the outside of the main body 10. The nozzle 151 is fixedly connected to the gun body 152 and faces the top center of the main body 10.

[0028] Preferably, the output end of the first drive motor 140 is fixedly connected to the mounting plate 170, and the gun body 152 is mounted on the mounting plate 170. The mounting plate 170 facilitates the installation and replacement of the spray gun 150 by the staff, thereby improving work efficiency.

[0029] Preferably, a connecting platform 180 is fixedly provided on the top of the support column 130, the first drive motor 140 is fixed on the connecting platform 180, and a support platform 190 with an arc-shaped top is fixedly provided on the connecting platform 180. The gun body 152 is set on the arc-shaped top surface of the support platform 190. On the one hand, the connecting platform 180 supports the first drive motor 140 to ensure that the first drive motor 140 rotates smoothly and does not shake. On the other hand, the connecting platform 180 facilitates the installation and replacement of the first drive motor 140 by the staff. The support platform 190 supports the gun body 152, making the rotation of the gun body 152 more stable.

[0030] Preferably, a buffer pad 200 is fixedly provided on the arc-shaped top surface of the support platform 190, and the gun body 152 is placed on the buffer pad 200. The buffer pad 200 can reduce the friction of the contact surface when the gun body 152 rotates, thus avoiding material loss.

[0031] Preferably, a horizontal filter screen 210 is fixedly installed inside the main body 10. The height of the filter screen 210 is located between the spray gun 150 and the third air supply pipe 80 to prevent particles on the filter screen 210 from entering the third air supply pipe 80.

[0032] Preferably, a temperature sensor 220 is fixedly installed on the upper surface of the inner wall of the vacuum cleaner 30, so that the staff can observe the temperature of the hot air that is about to enter the main body 10 and ensure that the moisture in the slurry inside the main body 10 is fully evaporated.

[0033] The working principle of this embodiment, and its more specific process, are as follows:

[0034] The operator starts the spray tower device, and the heating furnace 20 heats the air inside the furnace to the required temperature (usually around 600°C). The hot air enters the vacuum cleaner 30 through the first air supply pipe 60. The vacuum cleaner 30 removes particulate impurities from the hot air. The dust-removed hot air enters the main body 10 through the second air supply pipe 70. At this time, the ceramic slurry enters the gun body 152 through the feed port 153 and is sprayed out from the nozzle 151 towards the top center of the main body 10. The ceramic slurry and the hot air quickly come into contact and exchange heat. The hot air rapidly evaporates the water vapor in the ceramic slurry, causing the ceramic slurry to dry rapidly into granules. The finished granules, under the influence of gravity, pass through the filter screen 210 and then... The material flows out from the outlet 160. Particles that do not meet the standards remain on the filter screen 210 and are collected by the staff. After the hot air completes the heat exchange, the temperature drops rapidly (usually to about 100°C) and enters the bag filter 40 through the third air supply pipe 80. Due to the air flow, small finished particles inevitably enter the bag filter 40 with the air flow. The bag filter 40 can adsorb and filter the finished particles in the air. The dust-removed air enters the exhaust fan 50 through the suction pipe 90. Then, part of the air enters the heating furnace 20 again through the return air pipe 110 for heating and recycling, saving energy. Part of the air is discharged outside the device through the exhaust pipe 100.

[0035] Since the main body 10, heating furnace 20, vacuum cleaner 30, bag dust collector 40 and exhaust fan 50 are connected as a whole through pipes, the operation of exhaust fan 50 creates negative pressure in the entire device, ensuring that air can flow freely between the components.

[0036] To ensure that the ceramic slurry can fully contact the hot air, the nozzle 151 is set upwards. However, this causes some ceramic slurry and finished particles to fall into the spray gun 150 or the edge of the nozzle, resulting in accumulation or even blockage. Therefore, when the spray gun 150 is working, the second drive motor 122 drives the lead screw 123 to rotate. The lead screw 123 drives the support column 130 to move horizontally back and forth, which in turn drives the connecting table 180 to move horizontally back and forth. Finally, the gun body 152 moves horizontally within the main body 10. During this process, some of the accumulated material at the nozzle 151 is shaken off. After the spray gun 150 has been working for a certain period of time, the first drive motor 140 drives the gun body 152 on the mounting plate 170 to rotate. The gun body 152 drives the nozzle 151 to rotate. During the rotation of the nozzle 151, the remaining accumulated material at the nozzle is thrown out, ensuring that the spray gun 150 can smoothly spray out the ceramic slurry.

[0037] It should be noted that:

[0038] A conveying device is connected to the feed port 153 to continuously supply ceramic slurry to the spray gun 150. This conveying device is a common conveying equipment in the field of ceramic drying and belongs to existing technology. Its conveying principle often adopts the method of changing the local pressure to make the ceramic slurry flow smoothly, such as setting up a booster pump.

[0039] Heating air in the heating furnace 20 is a gradual process. Therefore, if the air temperature detected by the temperature sensor 220 does not reach the standard, the spray gun 150 will not spray ceramic slurry to avoid insufficient drying of the ceramic slurry due to insufficient air temperature inside the main body 10 after it is sprayed out.

[0040] The structures of the heating furnace 20, vacuum cleaner 30, bag filter 40 and exhaust fan 50 are existing technologies and are commonly used components in the field of spray towers, so this solution will not describe them in detail.

[0041] The energy-saving spray tower of this utility model has a return air pipe 110 fixedly connected to the air outlet of the exhaust fan 50. The end of the return air pipe 110 away from the exhaust fan 50 is fixedly connected to the side wall of the heating furnace 20. Multiple horizontal drive devices 120 are fixedly arranged around the side wall of the main body 10. A support column 130 is provided on the horizontal drive device 120. A first drive motor 140 is fixedly arranged on the support column 130. The output end of the first drive motor 140 is fixedly connected to a spray gun 150 with the nozzle facing upward. The spray gun 150 passes through the side wall of the main body 10 and extends into the interior of the main body 10, so that the energy-saving spray tower can circulate the hot air after heat exchange, effectively saving energy consumption.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
