Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a ceramic blank drying chamber. Background Technology

[0002] Ceramic wet blanks are the initial embryos of ceramic art that have not been dried after shaping. They typically have a moisture content as high as 18%-25%, are soft and malleable. Their surfaces often retain fingerprints or tool marks, and have a matte, frosty texture. They must be handled carefully to prevent deformation. Wet blanks allow artists to perform secondary creations such as trimming and carving, but they are susceptible to external pressure or the influence of ambient temperature and humidity. Rapid dehydration should be avoided to prevent cracking. At this stage, the embryo is not yet fully shaped and is a critical window for adjusting the form of the ceramic work. It needs to be left to air dry or undergo a controlled drying process to lay the foundation for subsequent firing.

[0003] The drying of wet ceramic blanks often utilizes the waste heat of the kiln, with hot air being transported through pipes to the drying chamber to dry the wet blanks. However, directly using the hot air generated by the kiln can lead to unstable temperatures, making it impossible to heat and dehydrate the wet blanks evenly. Furthermore, the hot air may contain waste gas, which could contaminate the surface of the blanks. Therefore, a ceramic blank drying chamber is needed to meet people's needs. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a ceramic blank drying chamber, including a main body 1. To address the problems of unstable hot air temperature, which prevents uniform heating and dehydration of the wet blanks, and the potential contamination of the blank surface by waste gas, the main body 1 of the drying chamber includes a drying chamber 2 and an equipment chamber 3. The drying chamber 2 contains movable racks 21 and a heat spreader 22, which are staggered. The equipment chamber 3 houses an MVR compressor 31 and a heat exchanger 32, connected by a connecting pipe 33. The equipment chamber 3 also contains an inlet pipe 34 and an outlet pipe 35. When using waste heat from the kiln to dry the wet ceramic blanks, the movable racks 21 are engaged with the engaging slots 29 of the heat spreader 22 according to the size of the blanks. By changing the engaging positions, the height of the movable racks 21 can be flexibly adjusted. After placement, the hot air from the kiln is input through the air inlet pipe 34, pressurized by the MVR compressor 31, and reaches the heat exchanger 32. The heat of the hot air is transferred to the heat medium inside the heat exchanger 32, and the cooled gas is discharged through the air outlet pipe 35. After the heat medium inside the heat exchanger 32 is heated, it is connected to the heat spreader plate 22 through the heat medium transfer pipe 23, which raises the temperature of the heat spreader plate 22. Under the action of the heat spreader plate 22, the ceramic wet blanks on the movable placement rack 21 are heated evenly. At the same time, air circulation is formed inside the drying chamber 2 through the upper air outlet 26, the lower air outlet 27 and the circulating fan 28, which makes the air flow and avoids long-term heat drop and contraction, forming a temperature difference between the upper and lower spaces. At the same time, the air flow can accelerate the removal of moisture from the surface of the wet blanks, which is conducive to the drying of the wet blanks. During the heating process inside the drying chamber 2, water vapor may be formed. The water vapor is collected and condensed into droplets through the water collection tank 24 and collected into the condensate collection chamber 25.

[0022] Reference Figure 4 The heat exchanger 32 is equipped with a heat transfer pipe 23, and the heat spreader 22 is connected to the heat transfer pipe 23. The heat spreader 22 has a pipe inside, which is connected to the heat transfer pipe 23. Hot air reaches the heat exchanger 32 through the MVR compressor 31 and exchanges heat in the heat exchanger 32 to heat the heat transfer medium inside the heat exchanger 32. Cold air is discharged through the air outlet pipe 35.

[0023] Reference Figure 2The bottom of the drying chamber 2 is provided with a water collection tank 24, which is located below the heat spreader 22. The main body of the drying chamber 1 is provided with a condensate collection chamber 25. The water collection tank 24 is connected to the condensate collection chamber 25. During the drying process of the wet blank, water vapor will appear. The water vapor drips down and eventually collects in the condensate collection chamber 25 through the water collection tank 24.

[0024] Reference Figure 3 The drying chamber 2 is provided with an upper air inlet 26 and a lower air inlet 27. A circulating fan 28 is installed on one side of the main body 1 of the drying chamber. The upper air inlet 26 and the lower air inlet 27 are respectively connected to the circulating fan 28. The circulating fan 28 drives the air flow inside the drying chamber 2 to form a thermal circulation, so that the heat inside the drying chamber 2 is evenly distributed, and the gas flow accelerates the removal of moisture from the surface of the ceramic wet blank.

[0025] Reference Figure 3 One end of the air inlet pipe 34 is located outside the main body 1 of the drying chamber, and the other end of the air inlet pipe 34 is connected to the MVR compressor 31. The external end of the air inlet pipe 34 is connected to the hot air generated by the kiln, and the other end is connected to the MVR compressor 31. The hot air is pressurized by the MVR compressor 31 and then delivered to the heat exchanger 32.

[0026] Reference Figure 3 One end of the exhaust pipe 35 is located outside the main body 1 of the drying chamber, and the other end of the exhaust pipe 35 is connected to the heat exchanger 32. The hot air undergoes heat exchange through the heat exchanger 32, transferring the heat to the heat medium inside the heat exchanger 32, and then the cooled gas is discharged through the exhaust pipe 35.

[0027] Reference Figure 4 The heat spreader 22 has evenly distributed snap-fit ​​grooves 29. The two sides of the movable placement rack 21 are installed on the snap-fit ​​grooves 29. When placing the ceramic blank, the movable placement rack 21 is snapped into the snap-fit ​​grooves 29 of the heat spreader 22 according to the size of the blank, and the height between the movable placement racks 21 can be flexibly adjusted.

[0028] The working principle is as follows: When using the waste heat of the kiln to dry the ceramic blanks, the movable placement rack 21 is snapped onto the snap-fit ​​groove 29 of the heat spreader 22 according to the size of the blanks. By changing the snap-fit ​​position, the height between the movable placement racks 21 can be flexibly adjusted. After the ceramic blanks are placed, the hot air from the kiln is input through the air inlet pipe 34. After being pressurized by the MVR compressor 31, it reaches the heat exchanger 32. The heat of the hot air is transferred to the heat medium in the heat exchanger 32. The cooled gas is discharged through the air outlet pipe 35. The heat medium in the heat exchanger 32 is heated and then passes through the heat medium transfer pipe 2. 3 is connected to the heat spreader 22, which heats up the heat spreader 22. Under the action of the heat spreader 22, the ceramic wet blank on the movable rack 21 is heated evenly. At the same time, through the upper air outlet 26, the lower air outlet 27 and the circulating fan 28, air circulation is formed inside the drying chamber 2, which makes the air flow and avoids long-term heat drop and contraction, forming a temperature difference between the upper and lower spaces. At the same time, the air flow can accelerate the removal of moisture from the surface of the wet blank, which is conducive to the drying of the wet blank. During the heating process inside the drying chamber 2, water vapor may be formed. The water vapor is collected and condensed into droplets through the water collection tank 24 and collected into the condensate collection chamber 25.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
