DETAILED DESCRIPTION

[0022] The technical solutions of the present application will be further described in detail below in combination with specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example

[0024] A ceramic blank drying device, such as Figures 1 to 8 As shown, including the outer casing 1, it also includes: The intermediate shell 17 is fixed to the inner wall of the outer shell 1, and the inner shell 18 is fixed inside the intermediate shell 17.

A discharge shell 13 is provided above the feed shell 11. The dehydration structure 5, used to extrude excess water from the preform, is located at the bottom of the discharge shell 13. A cutting structure 6 is disposed inside the feed housing 11. The cutting structure 6 includes a protective shell 603 fixed inside the feed housing 11. A guide hopper 601 is fixed to the top of the protective shell 603. A connecting shaft 606 is rotatably connected inside the guide hopper 601. A blade 607 is fixed to the outside of the connecting shaft 606. A perforated plate 608 that is slidably connected to the blade 607 is rotatably connected to the outside of the connecting shaft 606. A power shaft 602 is rotatably connected to the inside of one side of the protective shell 603. Transmission components are provided at both ends of the power shaft 602. The beating structure 7, used to crush the blank blocks and blank particles, is located on the outside of the power shaft 602. The discharge shell 13 is sleeved on the other side of the outer shell 1. An exhaust pipe 14 is fixed on one side of the discharge shell 13, and a discharge hopper 15 is fixed at the bottom of the discharge shell 13. The dust filter structure 8, used to recover raw material dust from the exhaust gas, is located on one side inside the discharge shell 13.

[0025] A base 16 is fixed to the bottom of the discharge shell 13 and the feed shell 11. A geared motor 2 is installed at the top of the base 16. A drive gear 4 is fixed to the end of the output shaft of the geared motor 2. A driven gear ring 3 that meshes with the drive gear 4 is fixed to the outside of the outer shell 1. Limiting rings 10 that are fixed to the outer shell 1 are provided on both sides of the driven gear ring 3. Support wheels 9 that are slidably connected to the limiting rings 10 are fixed to both sides of the top of the outer shell 1.

[0026] In use, the wet embryo material is placed in the inside of the discharge shell 13, and the embryo material is transported to the inside of the feeding shell 11 by the dehydration structure 5 and is subjected to extrusion dehydration. The driving gear 4 is driven to rotate by the reduction motor 2, and the driving gear 4 is driven to rotate synchronously with the outer shell 1 by meshing with the driven gear ring 3. Meanwhile, the support wheel 9 limits and supports the rotating outer shell 1 through the limiting ring 10. The hot air pipe 12 is connected with the hot air machine or heater, so that the generated hot air is continuously delivered to the inside of the feeding shell 11 to dry the embryo material in the inside of the outer shell 1. The intermediate shell 17, the inner shell 18 and the outer shell 1 form a multi-layer drying cavity to prolong the residence time of the embryo material in the device. The dried embryo material is discharged through the discharge hopper 15.

[0027] In order to solve the problem that the water in the embryo material is not easy to dry; Figures 1 to 6 As shown, the transmission assembly includes a first bevel gear 604 rotatably connected to one side of the inside of the protection shell 603 and connected with the power shaft 602. The bottom end of the connecting shaft 606 is fixed with a second bevel gear 605 meshed with the first bevel gear 604. The outer side of the power shaft 602 is fixed with a first gear 612. One side of the inner shell 18 is fixed with a rotating ring 610. The inner side wall of the rotating ring 610 is fixed with an inner gear ring 611. The outer side of the rotating ring 610 is sleeved with an outer sleeve shell 609. One side of the outer sleeve shell 609 is fixed with a fixed frame 614 connected with the discharge shell 13. The inside of the outer sleeve shell 609 is rotatably connected with a second gear 613. The second gear 613 is meshed with the inner gear ring 611 and the first gear 612, respectively. The power shaft 602 extends to the outer side of the intermediate shell 17 and is connected with the first gear 612. The blade 607 is fixed in the inside of the bottom end of the feeding pipe 501 by bolts. The top end of the guide hopper 601 is connected with the bottom end of the feeding pipe 501.

[0028] In use, the outer shell 1 is rotated to drive the intermediate shell 17 to rotate synchronously, so that the intermediate shell 17 drives the inner gear ring 611 to rotate synchronously through the rotating ring 610. Then the inner gear ring 611 drives the first gear 612 to rotate through the driven second gear 613, so that the power shaft 602 rotates. The power shaft 602 drives the connecting shaft 606 to rotate through the first bevel gear 604 and the second bevel gear 605, and finally drives the connecting shaft 606 and the blade 607 in the inside of the guide hopper 601 to rotate synchronously. After the embryo material is treated by the dehydration structure 5, the dehydrated embryo material is pushed downward along the feeding pipe 501 by the spiral impeller 505. Then the embryo material contacts with the perforated plate 608 and is extruded from the through holes on the surface of the perforated plate 608. At the same time, the connecting shaft 606 drives the blade 607 to rotate, so that the blade 607 cuts the embryo material passing through the perforated plate 608, so that the embryo material is divided into small particles. These particles are then guided into the inside of the inner shell 18 through the guide hopper 601, which creates conditions for the full contact of the embryo material with hot air and further improves the drying efficiency.

[0029] In order to solve the problem that the water in the green material is not easy to be discharged, as shown in Figure 3 and Figure 4 The dehydration structure 5 includes a conveying pipe 501 fixed at the top end of the feeding shell 11 and connected with the discharging shell 13, a filter screen 506 fixed at the middle position of the conveying pipe 501, a collecting shell 502 sleeved outside the filter screen 506 and fixedly connected with the conveying pipe 501, a rotating shaft 504 rotatably connected inside the conveying pipe 501 and connected with a connecting shaft 606, a spiral impeller 505 fixed outside the rotating shaft 504, a drain pipe 503 fixed at the bottom end of one side of the collecting shell 502, and the pitch of the spiral impeller 505 gradually decreases along the conveying direction, and the diameter of the rotating shaft 504 gradually increases along the conveying direction.

[0030] In use, when the green material enters the equipment, the green material inside the discharging shell 13 is taken through the conveying pipe 501, and the connecting shaft 606 drives the rotating shaft 504 to rotate, so that the spiral impeller 505 rotates synchronously, and the green material is pushed to move downward along the conveying pipe 501. Then, the pitch of the spiral impeller 505 decreases and the diameter of the rotating shaft 504 increases, so that a continuous extrusion force is generated on the green material in the moving process. The excess water in the green material is squeezed out under the action of the extrusion force and penetrates through the filter screen 506 into the inside of the collecting shell 502. Then, the water is discharged through the drain pipe 503, the initial water content of the green material is reduced, the load of the subsequent drying link is reduced, and the problem that the green material is adhered and clumped due to too much water is avoided, which provides a prerequisite for uniform drying of the green material. Embodiment

[0031] A ceramic green material drying equipment, as shown in Figure 6 and Figure 7 In order to solve the problem that the dust of the green material is easy to be discharged with the waste gas, the filter dust structure 8 includes a connecting pipe 806 fixed outside the power shaft 602, an adjusting sleeve 807 threadedly connected outside the connecting pipe 806, a tension spring 808 fixed on one side of the adjusting sleeve 807, a guide rod 805 slidably connected inside one side of the connecting pipe 806, a plate brush 804 fixed on one side of the guide rod 805 and connected with the tension spring 808, a connecting sleeve 801 fixed on one side inside the discharging shell 13, a filter dust screen 803 fixed on one side of the connecting sleeve 801, a positioning frame 802 connected with the exhaust pipe 14 and fixed on one side of the filter dust screen 803, and the guide rod 805 and the connecting pipe 806 constitute a telescopic structure through the tension spring 808, and the front view cross section of the filter dust screen 803 is in a funnel-shaped inclined surface structure. In use, during the drying of the blanks, the exhaust gas generated carries part of the blank dust into the inside of the discharge shell 13, and the blank dust in the exhaust gas is filtered and intercepted by the dust filter net 803. At the same time, the power shaft 602 drives the connecting pipe 806 to rotate, so that the plate brush 804 sweeps the dust attached to the surface of the dust filter net 803, avoids the blockage of the dust filter net 803 affecting the exhaust gas emission, and the dust swept down falls into the discharge hopper 15 for recycling. The plate brush 804 is in close contact with the dust filter net 803 through the elastic force of the tension spring 808, and the rotating adjusting sleeve 807 adjusts the elastic force of the tension spring 808, which reduces the pollution of the exhaust gas emission to the environment and guarantees the cleanliness and safety of the equipment operating environment.

[0032] As shown in Figure 8 The beating structure 7 includes a fixed seat 701 fixed outside the power shaft 602 and inside the inner shell 18, a rotating seat 704 fixed on the outer side wall of the fixed seat 701, a turnover rod 703 rotatably connected inside the rotating seat 704, and a beating plate 702 fixed at the end of the turnover rod 703 away from the rotating seat 704.

[0033] In use, after the divided blanks enter the inside of the inner shell 18, the fixed seat 701 is driven to rotate by the power shaft 602, so that the rotating seat 704 drives the turnover rod 703 to move and lift, and then the turnover rod 703 rotates around the rotating seat 704 under the action of gravity, so that the beating plate 702 beats the blank blocks and particles to crush the blank blocks and particles, and solves the problem of uneven drying caused by blank accumulation.

[0034] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto.
