Description

Technical Field

[0001] The present invention relates to the technical field of ceramic processing equipment, and particularly relates to a drying device for ceramic blanks used in ceramic production. Background Art

[0002] The drying of ceramic blanks is a key link in the ceramic manufacturing process, which can directly affect product quality, energy consumption and production efficiency. Traditional drying methods can be divided into natural drying and hot air drying. Among them, natural drying mainly realizes moisture migration through air convection and evaporation, with the advantages of simple operation and low cost. The disadvantage is that it is restricted by the climate, depends on the environmental temperature and humidity, and is prone to cause cracking and deformation of the blanks, and is mainly applicable to small workshops or low-value-added products. Hot air drying uses hot air at 60–120°C to conduct forced convection on the ceramic blanks to accelerate moisture evaporation. Its efficiency is higher than that of natural drying, but there are problems of high energy consumption and uneven temperature distribution, and stress cracks are easily generated. This is mainly because there are differences in the wall thickness and shape of each part of the ceramic blank, so the actual drying temperatures required for each part are not the same. Uneven shrinkage of the blank leads to internal stress. Especially at the critical moisture content stage, gradient temperature control is required to relieve the stress. However, the traditional drying device cannot adjust the temperature of local units, and the hot air blown out mainly acts on the surface of the blank and is difficult to reach the inside. Therefore, only long-term drying can be used to slowly evaporate the moisture of the blank, so that the drying progress of each part is kept as consistent as possible to avoid cracks. This not only affects the drying efficiency but also increases energy consumption. A new type of drying device is needed to solve the above problems. Summary of the Invention

The drying oven 4 is divided into upper and lower layers by an internal filter box 7. The top exhaust port 701 of the filter box 7 is located at the notch of the middle partition 402 of the drying oven 4. A number of layers of filter elements 702 are provided in the filter box 7. The filter elements 702 are placed on the support filter screen 703 on the bottom surface of the filter box 7. An infrared probe 8 is provided on the upper back plate of the drying oven 4. The tail spring wire 801 of the infrared probe 8 passes through the drying oven 4 and is connected to the external control panel 9 of the chassis 1. The infrared probe 8 can monitor the temperature distribution at the upper open part on the opposite surface of the drying oven 4 in real time.

[0020] In this embodiment, the unit tubes 5 capable of sliding horizontally are arranged in the opening of the oven 4, and the unit tubes 5 can be selected and mixed with various specifications, and the electric heating block 6 is suspended at the output port of the unit tube 5. The upper side plate of the oven 4 is provided with positive and negative conductive slide rails 401 at intervals, and the conductive slide rails 401 are electrically connected to the control power supply 10 outside the oven 4, and the control power supply 10 is electrically connected to the control panel 9. The positive and negative conductive slide rails 401 are respectively slidably connected to the positive and negative conductive convex strips 501 outside the first row of unit tubes 5, and one end of the positive and negative conductive convex strips 501 is respectively connected to the positive and negative electrodes of the electric heating block 6, and the other end is respectively connected to the positive and negative electric slide grooves 502 inside the unit tube 5, and the positive and negative electric slide grooves 502 are respectively slidably connected to the positive and negative conductive convex strips 501 of the adjacent unit tubes 5 on the same layer.

[0021] In this embodiment, the lower layers of the two ovens 4 on opposite sides are connected by a circulation mechanism, which includes a half bellows 18, which is connected to the corresponding oven 4 through a telescopic spring tube 19, and the two half bellows 18 are respectively connected to the two end surfaces of the wind wheel 20 through a rotating sealing ring, and the outer gear ring 2001 of the wind wheel 20 is meshed with the output end gear of the circulation motor 21, and the circulation motor 21 is installed on one half bellows 18. A driving assembly is provided above the circulation mechanism, and the driving assembly can lift the turntable 301 connected to the carrier plate 3, and the driving assembly includes a lifting cylinder 22, and the cylinder body of the lifting cylinder 22 is installed on both sides of the circulation mechanism. The piston rod of the lifting cylinder 22 is vertically connected to the two ends of the bottom of the lifting cylinder 23, and the lifting cylinder 23 has a built-in driving motor 24, and the output end gear of the driving motor 24 is meshed with the bottom end gear of the transmission shaft 25, and the shaft body of the transmission shaft 25 is rotatably connected to the lifting cylinder 23, and the outer spline at the upper end of the transmission shaft 25 is matched with the inner spline at the bottom of the turntable 301.

[0022] The working principle of the present invention is as follows: The extension of each unit tube 5 is adjusted according to the shape of the blank to be dried so that it fits the outer surface of the blank more closely, which is convenient for close drying. The conveying motor 30 is started to deliver the carrier plate 3 carrying the blank into the chassis 1. When the carrier plate 3 arrives at the drying station, the positioning cylinder 28 rises to limit the carrier plate 3. The lifting motor 13 is started to drive the double-layer clamping tube 2 to go down and insert into the blank. The circulating air pump 15 and the electric heater 16 are started to blow hot air into the outer tube of the double-layer clamping tube 2. The hot air is discharged through the exhaust hole 202 to dry the inside of the blank. The steam from the drying enters the inner tube from the bottom of the double-layer clamping tube 2 and is sent to the clean air box 17 through the central tube 14. The air after dust removal and water removal returns to the circulating air pump 15 for the next cycle.

[0023] like Figure 1As shown, when the ceramic blank is axisymmetric, only the unit tube 5 needs to be arranged in one side of the oven 4, and the infrared probe 8 on the opposite side directly irradiates the surface of the blank to monitor its real-time temperature. The lifting cylinder 22 is started to insert the transmission shaft 25 into the bottom of the turntable 301, and the driving motor 24 is started to drive the blank to rotate. During the rotation process, the circulation motor 21 is started to blow air into the oven 4 equipped with the unit tube 5, and the control power supply 10 inputs current to the positive and negative conductive slide rails 401 of each layer. The electric heating blocks 6 on the same layer in parallel state have the same temperature (if there is a need for differentiation, they can also be wired independently), and the heating power of the electric heating blocks 6 on different layers can be set differently through the current size to meet the temperature requirements of different parts of the blank and realize gradient temperature control. The blasted airflow is heated by the electric heating block 6 and blown to the outer surface of the blank, and then carries water vapor into the opposite side oven 4, and then filtered by the filter box 7 and returns to the circulation mechanism. During the drying process, the reciprocating cylinder 32 can adjust the distance between the electric heating block 6 and the blank as needed.

[0024] like Figure 2 As shown, when the ceramic body is non-axisymmetric, unit tubes 5 can be installed in the ovens 4 on both sides, and the specifications of the unit tubes 5 can be selected according to the actual gradient requirements. During the blasting process, the circulating motor 21 can be reversed to change the direction of the circulating airflow, so that the outer surface of the body is heated more evenly. The present invention can differentiate and accurately dry the inside and outside of each part of the ceramic body according to the characteristics of the ceramic body, and can monitor the temperature distribution of the body in real time and display it on the control screen, which is convenient for the operator to control and adjust. Digital and modular drying of ceramic bodies is realized, which has the characteristics of high efficiency, energy saving, high degree of automation and strong applicability.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
