Description

Technical Field

[0001] This utility model relates to the field of ceramic firing equipment technology, specifically to a drying kiln structure for ceramic firing. Background Technology

[0002] In the ceramic production process, one step is to dry the ceramic blanks so that they can be printed or carved. The ceramics are placed inside a drying kiln, and hot air is blown onto the ceramic blanks by a blower to dry them.

[0003] For example, the utility model patent "Structure of Drying Kiln for Ceramic Firing" (publication number: CN213238180U) uses a bent arc-shaped guide frame in conjunction with a ceramic placement rack to allow purified hot air to dry the wet ceramic blanks in an orderly manner. It also has good dust removal and dehumidification effects, preventing dust and water droplets from damaging the ceramic blanks. However, in the implementation of this patent, the heating rod is directly installed inside the air inlet hood. When the gas is blown into the air inlet hood, it cannot fully contact the heating rod, making it difficult to heat the gas fully and evenly, which can easily affect the drying effect. Furthermore, after the hot air enters the sealed drying kiln box, it cannot be evenly distributed to different positions, making it difficult to dry the ceramic blanks in different positions evenly.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides an embodiment of a drying kiln structure for ceramic firing, comprising a drying and sealing kiln box 1, a blower chamber 7, and a heating chamber 22. The heating chamber 22 is installed on the top of the drying and sealing kiln box 1, and the blower chamber 7 is installed at one end of the heating chamber 22. A blower fan 10 is installed inside the blower chamber 7, and a solenoid valve 9 (e.g., HYZF2-15) is installed at the end of the blower chamber 7 away from the heating chamber 22. An air inlet pipe 8 is installed at the input end of the solenoid valve 9, and a dust filter is installed inside the air inlet pipe 8. Gas enters the blower chamber 7 through the air inlet pipe 8, and the dust filter filters dust from the gas. A diversion chamber 12 is installed at the top inside the heating chamber 22, and a gas collecting chamber 14 is installed at the bottom inside the heating chamber 22. Heating tubes 15 are evenly installed at the bottom of the diversion chamber 12. All 15 heating tubes are connected to the gas collection chamber 14, and electric heating wires 13 are wound around the outside of each heating tube 15. An installation plate 4 is installed inside the drying and sealing kiln box 1, and an air guide chamber 5 is set inside the installation plate 4. Ceramic drying plates 3 are evenly installed on the outside of the installation plate 4. Air outlets 20 are set at the bottom of both ends of the drying and sealing kiln box 1, and electric cylinders 18 are installed at the top of both ends of the drying and sealing kiln box 1. The electric cylinder 18 can be model J64RT2UNIVER. A control panel 16 is installed at the end of the heating chamber 22 away from the blower chamber 7. The output end of the control panel 16 is electrically connected to the input end of the solenoid valve 9, the blower fan 10, the electric heating wire 13 and the electric cylinder 18 through wires. A door 21 is installed on one side of the drying and sealing kiln box 1, and a handle is installed on the outside of the door 21 for easy loading and unloading of ceramics.

[0022] like Figure 1As shown, a first air guide pipe 11 is installed at one end of the blower chamber 7 near the heating chamber 22. The first air guide pipe 11 passes through the heating chamber 22 and extends into the interior of the diversion chamber 12. A second air guide pipe 17 is installed at the bottom of the gas collecting chamber 14. The second air guide pipe 17 passes through the drying and sealing kiln box 1 and extends into the interior of the air guide cavity 5. The first air guide pipe 11 enters the interior of the diversion chamber 12 and can be diverted to the interior of multiple sets of heating tubes 15. The gas inside the heating tubes 15 is heated by the electric heating wire 13. The heated gas enters the interior of the gas collecting chamber 14 through the heating tubes 15.

[0023] like Figure 1-3 As shown, each of the ceramic drying plates 3 is equipped with a diversion pipe 6. The diversion pipe 6 passes through the mounting plate 4 and extends into the air guide cavity 5. Drying pipes 19 are evenly installed on the outside of the diversion pipe 6. Hot air can be evenly diverted into the interior of multiple diversion pipes 6 and blown evenly to different positions through the drying pipes 19, so that the ceramics at different positions can be dried evenly.

[0024] like Figure 1-2 As shown, the output end of the electric cylinder 18 is equipped with a sealing baffle 2. After drying, the solenoid valve 9 can be closed, and the electric cylinder 18 can be used to push the sealing baffle 2 to move. The air outlet 20 can be blocked by the sealing baffle 2, thus sealing the inside of the drying and sealing kiln box 1, which facilitates the production process such as ceramic firing.

[0025] Working principle:

[0026] When in use, connect the device to the power supply, place the ceramic blanks on different ceramic drying plates 3, and then close the door 21.

[0027] During drying, the operator can activate two sets of electric cylinders 18 through the control panel 16, so that the electric cylinders 18 pull the sealing baffle 2 upward, so that the sealing baffle 2 no longer blocks the air outlet 20. Then the operator can activate the blower fan 10 and the electric heating wire 13 through the control panel 16, and open the solenoid valve 9 through the control panel 16.

[0028] At this time, the blower fan 10 works, allowing outside gas to enter the blower chamber 7 through the air inlet pipe 8, and then enter the distribution chamber 12 through the first air guide pipe 11. After entering the distribution chamber 12, the gas can be distributed to multiple sets of heating tubes 15, and the gas inside the heating tubes 15 is heated by the electric heating wire 13. This helps to increase the heating area, so that the gas can be fully heated and improve the drying effect on the ceramic blank.

[0029] Hot air enters the gas collecting chamber 14 through the heating pipe 15, and then enters the gas guiding chamber 5 through the second gas guiding pipe 17. The hot air can be evenly distributed into the multi-component distribution pipe 6, and can be evenly blown to different positions through the drying pipe 19, so that the ceramics at different positions can be dried evenly. The hot air can be discharged from the drying sealed kiln box 1 through the air outlet 20, thus completing the drying process of the ceramics.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
