Description

Technical Field

[0001] The invention relates to the technical field of ceramic powder production and processing, and in particular to a conveying structure and ceramic powder drying equipment. Background Art

[0002] Ceramic micro powder is a lightweight non-metallic multifunctional material, the main components are SiO2 and Al2O3, good dispersibility, high hiding power, high whiteness, good suspension, good chemical stability, good plasticity, high heat resistance, low density, low ignition loss, good light scattering, good insulation. It can improve the performance of coatings, improve the mechanical properties of paint films, increase transparency, improve fire resistance, and can be used for anti-corrosion, fire prevention, high temperature resistance, powder, architectural coatings and various industries. Ceramic powder cannot be separated from the drying process in the production process.

[0003] A ceramic powder drying device disclosed in Chinese patent publication number CN202410703105.7 includes a rotary dryer and a quantitative device, wherein a connecting plate is fixedly installed on the surface of the rotary dryer, a discharge pipe is fixedly installed on the circumferential surface of the rotary dryer, a feed frame is fixedly installed on the surface of the connecting plate, and the feed frame is connected to the inside of the rotary dryer. The feed frame is sealed by rotating the unloading plate. After the seal of the feed frame is released, the quantitative ceramic powder on the top of the unloading plate enters the rotary dryer through the feed frame for dehydration and drying, and the precise Controlling the feed amount of ceramic powder helps to ensure that the contact time and temperature distribution of the ceramic powder and hot air during the drying process are uniform, ensuring the stable drying quality of the product and reducing uneven drying caused by insufficient or excessive feed. At the same time, when a large amount of ceramic powder is thrown onto the top of the feed plate, the rubber block slowly deforms so that the feed plate and the connecting rod can only move downward slowly. The sudden influx of a large amount of powder will cause sudden changes in parameters such as temperature and humidity inside the drying equipment, affecting the drying effect. The slow movement of the feed plate can prevent the influx of a large amount of powder, further ensuring the drying quality of the ceramic powder.

[0004] In the prior art, ceramic powders mostly enter the drying chamber in a clumping manner, which makes it difficult to ensure the uniform distribution of the ceramic powders before drying. At the same time, after a large amount of ceramic powders are transported into the drying chamber at one time, the clumped ceramic powders dry more slowly, making it difficult to achieve consistent drying of the ceramic powders, which seriously affects the drying efficiency of the ceramic powders.

[0016] (II) Beneficial effects

[0017] The present invention provides a conveying structure and a ceramic powder drying device, which have the following beneficial effects:

[0018] The present invention provides a conveying structure, wherein after the ceramic powder is blown into the drying flow channel, since the electrostatic adsorption cannot completely adsorb the ceramic powder at one time, the subsequent ceramic powder will enter the U-shaped flow channel and then return to the drying flow channel, which can effectively reduce the flow rate of the ceramic powder entering the first area of ​​the electrostatic adsorption plate, so that the powder can be adsorbed more efficiently, and after the electrostatic adsorption plate 2 adsorbs the ceramic powder, as the amount of powder accumulates, the ceramic powder will enter the gap of the drying plate through the gap of the electrostatic adsorption plate 2, and through the narrow gap channel, the uniformity of the powder entering the gap of the drying plate is maintained;

[0019] At the same time, the hot air blown by the hot air blower will heat the drying plate after entering the hot air flow channel, and the gap between adjacent drying plates will be heated, providing an environment with a certain temperature for the ceramic powder. Part of the hot air in the hot air flow channel will enter the gap between adjacent drying plates through the pores, so that the ceramic powder can be further dried. The vertical output design structure of the pores can form a slight negative pressure in the gap between the two electrostatic adsorption plates, thereby ensuring the speed at which the ceramic powder enters the gap between the drying plates.

[0020] In addition, the transfer tank is used to place processed ceramic powder. The conveying assembly is driven by a driving motor to rotate, so that the ceramic powder is transported to the top of the elastic partition. The fan blows air to the top of the elastic partition, so that the air pressure above the elastic partition gradually increases, thereby causing the elastic partition to deform. When the air pressure increases to drive the rotating partition to rotate, the elastic partition recovers its deformation and discards the ceramic powder on it, making the ceramic powder loose. The powder passes through the barrier box with the airflow and enters the transfer tank to complete drying, effectively avoiding the transportation of ceramic powder in clusters, and blowing out the ceramic powder with less wind force. At the same time, it also avoids the problem of incomplete drying caused by too much powder input into the drying channel. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1-6 As shown, this embodiment provides a conveying structure, including an L-shaped drying channel 100, the upper end surface of the drying channel 100 is fixedly connected to a circulation box 101, a plurality of groups of U-shaped channels 104 are arranged inside the circulation box 101, a hot air blower 103 is installed on one side of the outside of the drying channel 100, and an exhaust grille 102 is installed on the other side, a drying component is arranged inside the circulation box 101, and the drying component includes a plurality of groups of electrostatic adsorption plates 105 arranged at intervals, the lower end surface of the electrostatic adsorption plate 105 is fixedly connected to an electrostatic adsorption plate 2 107, and the lower end surface of the electrostatic adsorption plate 2 107 is fixedly connected to a drying plate 108.

[0037] Specifically, after entering the drying channel 100, the ceramic powder will be adsorbed by the electrostatic adsorption plate 1 105 and the electrostatic adsorption plate 2 107, so that the ceramic powder is dried in a more uniform manner, thereby effectively improving the drying effect and drying efficiency of the powder.

[0038] Furthermore, two ends of the U-shaped flow channel 104 communicate with the gaps between two adjacent groups of U-shaped flow channels 104 , and partition grooves 106 are provided outside the U-shaped flow channel 104 , and the partition grooves 106 outside several groups of U-shaped flow channels 104 are staggered.

[0039] Specifically, after the ceramic powder is blown into the drying channel 100, since electrostatic adsorption cannot completely adsorb the ceramic powder at one time, the subsequent ceramic powder will enter the U-shaped channel 104 and then return to the drying channel 100, which can effectively reduce the flow rate of the ceramic powder entering the electrostatic adsorption plate 105 area, so that the powder can be adsorbed more efficiently.

[0040] It can be understood that both ends of the U-shaped flow channel 104 are connected to the same gap.

[0041] Furthermore, the gap between two adjacent groups of electrostatic adsorption plates 107 gradually decreases along the vertical direction, and the gap between two adjacent groups of drying plates 108 gradually increases along the vertical direction.

[0042] Specifically, after the electrostatic adsorption plate 107 adsorbs the ceramic powder, as the amount of powder accumulates, the ceramic powder will enter the gap of the drying plate 108 through the gap of the electrostatic adsorption plate 107 and maintain the uniformity of the powder entering the gap of the drying plate 108 through the narrow gap channel.

[0043] Furthermore, a hot air flow channel 109 is provided inside the drying plate 108 , one end of the hot air flow channel 109 is connected to the hot air blower 103 , and the other end of the hot air flow channel 109 is connected to the exhaust grille 102 .

[0044] Specifically, the hot air blown by the hot air blower 103 enters the hot air flow channel 109 and heats the drying plates 108 , and the gaps between adjacent drying plates 108 are heated, thereby providing an environment with a certain temperature for the ceramic powder.

[0045] It is understandable that the gaps between adjacent drying plates 108 are not connected to the exhaust grille 102 .

[0046] Furthermore, the interval sides of the plurality of drying plates 108 are provided with air holes 110 distributed in an array, and the output ends of the air holes 110 are vertically downward.

[0047] Specifically, part of the hot air in the hot air flow channel 109 will enter the gap between adjacent drying plates 108 through the air holes 110, so that the ceramic powder can be further dried.

[0048] It should be noted that the vertical output design structure of the air hole 110 can form a slight negative pressure in the gap of the second electrostatic adsorption plate 107, thereby ensuring the speed at which the ceramic powder enters the gap of the drying plate 108.

[0049] like Figure 7-9 As shown, the present embodiment also provides a ceramic powder drying device, including the conveying structure as described above, and also including a transfer tank 200 and a barrier box 300. A fan 201 is installed on the outside of the transfer tank 200, and a drive motor 202 is installed on the upper end surface of the transfer tank 200. A transfer cavity is arranged inside the transfer tank 200, and a sleeve 203 and a conveying component 205 are arranged inside the transfer cavity. The sleeve 203 is sleeved inside the conveying component 205, and an elastic partition 204 is fixedly connected inside the transfer cavity. The output end of the transfer tank 200 is connected to the input end of the drying channel 100, and the input section of the transfer tank 200 is connected to the output end of the transfer tank 200.

[0050] Furthermore, one end of the sleeve 203 is fixedly connected to the top of the transfer chamber, and a discharge trough is provided outside the sleeve 203 .

[0051] Furthermore, the elastic barrier 204 is made of elastic material, the elastic barrier 204 is fixedly connected to the outside of the sleeve 203 , the discharge chute is arranged above the elastic barrier 204 , and the output end of the fan 201 is connected to the top of the elastic barrier 204 .

[0052] Furthermore, a magnetic strip 301 is fixedly connected to the top of the inner cavity of the barrier box 300 , and a rotating partition 302 is rotatably connected to the inner cavity of the barrier box 300 .

[0053] Furthermore, the weight of the side of the rotating partition 302 that contacts the bottom of the blocking box 300 is greater than the weight of the other side, and the side of the rotating partition 302 that contacts the top of the blocking box 300 is attracted to the magnetic strip 301 .

[0054] Specifically, the transfer tank 200 is used to place processed ceramic powder. The conveying component 205 is driven to rotate by the driving motor 202 to transport the ceramic powder to the top of the elastic partition 204. The fan 201 blows air to the top of the elastic partition 204, so that the air pressure above the elastic partition 204 gradually increases, thereby causing the elastic partition 204 to deform. When the air pressure increases to drive the rotating partition 302 to rotate, the elastic partition 204 restores its deformation and discards the ceramic powder above, making the ceramic powder loose. The ceramic powder passes through the barrier box 300 with the air flow and enters the drying channel 100 to complete drying, effectively avoiding the ceramic powder from being transported in clusters, and the ceramic powder can be blown out with less wind force. At the same time, it also avoids the problem of incomplete drying caused by too much powder input into the drying channel 100.

[0055] Working principle: When drying ceramic powder, the input end of the transfer tank 200 is connected to the ceramic powder processing production line. After the ceramic powder comes off the production line, it is directly input into the bottom of the inner cavity of the transfer tank 200. The driving motor 202 drives the conveying assembly 205 to transport the ceramic powder to the top of the elastic interlayer 204. At the same time, the fan 201 blows air to the top of the elastic interlayer 204, so that the air pressure above the elastic interlayer 204 gradually increases, thereby causing the elastic interlayer 204 to deform. When the air pressure increases to the pushing pressure, the ceramic powder is transported to the top of the elastic interlayer 204. When the movable rotating partition 302 rotates, the elastic partition 204 recovers its deformation and discards the ceramic powder on the top, making the ceramic powder loose and passing through the barrier box 300 with the air flow into the drying channel 100. After the ceramic powder enters the drying channel 100, the electrostatic adsorption plate 1 105 and the electrostatic adsorption plate 2 107 will adsorb the ceramic powder on the surface. When the adsorption amount is sufficient, the ceramic powder enters the gap of the drying plate 108 through the gap of the electrostatic adsorption plate 2 107 to complete drying, and is then discharged.

[0056] The conveying structure and ceramic powder drying equipment provided by the present invention: by setting a conveying structure, after the ceramic powder is blown into the drying channel 100, since the electrostatic adsorption cannot completely adsorb the ceramic powder at one time, the subsequent ceramic powder will enter the U-shaped channel 104 and then return to the drying channel 100, which can effectively reduce the flow rate of the ceramic powder entering the electrostatic adsorption plate 1 105 area, so that the powder can be adsorbed more efficiently, and after the electrostatic adsorption plate 2 107 adsorbs the ceramic powder, as the amount of powder accumulates, the ceramic powder will enter the gap of the drying plate 108 through the gap of the electrostatic adsorption plate 2 107, and through the narrow gap channel, the uniformity of the powder entering the gap of the drying plate 108 is maintained;

[0057] At the same time, the hot air blown by the hot air blower 103 enters the hot air flow channel 109 and heats the drying plate 108. The gaps between adjacent drying plates 108 are heated, providing an environment with a certain temperature for the ceramic powder. Part of the hot air in the hot air flow channel 109 enters the gaps between adjacent drying plates 108 through the air holes 110, so that the ceramic powder is further dried. The vertical output design structure of the air holes 110 can form a slight negative pressure in the gap of the electrostatic adsorption plate 107, thereby ensuring the speed at which the ceramic powder enters the gap of the drying plate 108.

[0058] In addition, the transfer tank 200 is used to place processed ceramic powder. The conveying component 205 is driven to rotate by the driving motor 202 to transport the ceramic powder to the top of the elastic partition 204. The fan 201 blows air to the top of the elastic partition 204, so that the air pressure above the elastic partition 204 gradually increases, thereby causing the elastic partition 204 to deform. When the air pressure increases to drive the rotating partition 302 to rotate, the elastic partition 204 recovers its deformation and discards the ceramic powder on it, making the ceramic powder loose. The powder passes through the barrier box 300 with the air flow and enters the transfer tank 200 to complete drying, effectively avoiding the transportation of ceramic powder in clusters during transportation, and the ceramic powder can be blown out with less wind force. At the same time, it also avoids the problem of incomplete drying caused by excessive powder input into the drying channel 100.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
