Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to a glaze drying equipment for ceramic product processing. Background Technology

[0002] Ceramics is a general term for pottery and porcelain, and it is also a type of craft art in my country. As early as the Neolithic Age, my country already had painted pottery and black pottery with a rough and simple style. Pottery and porcelain have different textures and properties. Pottery is made primarily from clay with high viscosity and strong plasticity. It is opaque, has fine pores and weak water absorption, and produces a dull sound when struck. Porcelain is made from clay, feldspar, and quartz. It is translucent, non-absorbent, corrosion-resistant, has a hard and dense body, and produces a crisp sound when struck. Ceramics are made from clay blanks. During the processing of clay blanks, glaze needs to be sprayed onto the surface of the clay blanks. The glaze is applied to the surface of the ceramic to improve the appearance and performance of the ceramic products. After the glaze is applied to the surface of the ceramic blank, it needs to be dried using drying equipment. The purpose of the drying equipment is to gently and effectively remove the moisture from the glaze by providing suitable temperature, ventilation and other conditions, so that the glaze changes from a wet and soft state to a relatively dry and stable state. In this way, during the subsequent firing process, the glaze can melt and spread more evenly on the surface of the blank, thereby forming a high-quality glaze layer and improving the appearance and performance of the ceramic products.

[0003] Existing drying equipment, such as the ceramic glaze drying device disclosed in CN212930726U, uses an air pipe to blow hot air from a hot air blower into the drying chamber through an air outlet, thus distributing the hot air evenly inside the chamber. An exhaust fan then draws the cooled hot air outwards, preventing the internal temperature of the drying chamber from dropping. Furthermore, an electric heating plate is installed on top of the placement platform inside the drying chamber to further dry the ceramic glaze, resulting in more uniform drying and improved production efficiency. However, the surface temperature of the ceramic glaze remains high after drying, making it difficult to remove quickly. After removal, it must either be allowed to cool naturally or use other cooling equipment. This increases the number of production steps, extends the production cycle, or requires additional cooling equipment, increasing the overall footprint of the equipment and hindering continuous production, potentially impacting work efficiency. Summary of the Invention

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a glaze drying device for ceramic product processing to solve the above-mentioned technical problems.

A rotating plate is movably installed in each of the picking area, the drying area, and the cooling area. The rotating plate is used to drive a single ceramic to rotate horizontally. Each rotating plate is provided with a limiting component for positioning the ceramic part.

[0015] The beneficial effects of this utility model are:

Detailed Implementation

[0023] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0024] like Figures 1 to 3As shown, this utility model provides a glaze drying equipment for ceramic product processing, including a drying box 1, a processing cylinder 2, a conveyor frame 3, a partition 4, a rotating plate 5, a hot air blower 6, a cold air blower 7, an exhaust pipe 8, a box door 9, a limiting component 10, and an exhaust component 11. A circular processing cylinder 2 is installed inside the drying box 1, and a box door 9 is installed on the inner front end of the drying box 1 through a hinge.

[0025] The processing cylinder 2 is equipped with a circular conveyor frame 3 that is rotatably connected to the drying box 1. The front end of the processing cylinder 2 is an open structure. The drying box 1 is equipped with a first motor for driving the conveyor frame 3 to rotate (not shown in the figure).

[0026] Three partitions 4 are vertically installed on the conveyor frame 3. The conveyor frame 3 is used to drive all ceramics to rotate synchronously. The partitions 4 divide the inner side of the processing cylinder 2 into a picking area, a drying area and a cooling area. The picking area is connected to the front end of the processing cylinder 2. A circular rotating plate 5 is rotatably installed in each of the picking area, drying area and cooling area. The rotating plate 5 is used to drive a single ceramic to rotate horizontally. Each rotating plate 5 is provided with a limiting component 10 for positioning the ceramic part. The conveyor frame 3 is provided with a second motor for driving the rotating plate 5 to rotate horizontally (not shown in the figure).

[0027] A hot air blower 6 and a cold air blower 7 are installed on the top of the drying chamber 1. Each of the hot air blower 6 and the cold air blower 7 is connected to an exhaust pipe 8. The two exhaust pipes 8 pass through the drying chamber 1 and are connected to the drying area and the cooling area respectively.

[0028] The rear end of the processing cylinder 2 is provided with an exhaust assembly 11, which is used to exhaust the hot and cold air inside the processing cylinder 2 to the outside.

[0029] In this embodiment, the partition 4 includes a hollow aluminum alloy plate 41 that is fixed to the top of the conveyor frame 3 by bolts. A ceramic fiber plate 42 is provided inside the hollow aluminum alloy plate 41, and the ceramic fiber plate 42 is used to provide heat insulation for the picking area, drying area and cooling area.

[0030] In this embodiment, the exhaust assembly 11 includes a three-way pipe 111 and an exhaust fan 112 disposed at the rear end of the drying chamber 1. The rear end of the three-way pipe 111 is connected to the exhaust end of the exhaust fan 112. A connecting pipe 113 is installed on each of the left and right sides of the front end of the three-way pipe 111. One connecting pipe 113 is connected to the inside of the cooling zone, and the other connecting pipe 113 is connected to the exhaust pipe 8 at the air outlet of the hot air blower 6. A valve 114 is installed on the connecting pipe 113, and the gas flow in the connecting pipe 113 can be controlled by the valve 114.

[0031] The exhaust pipe 8, the three-way pipe 111 and the connecting pipe 113 mentioned above are all made of stainless steel, but aluminum alloy can also be used. They have high hardness and long service life.

[0032] Specifically, in use, each electrical device is electrically connected to an external controller. The ceramic with glaze is placed on the rotating plate 5 of the take-up area through the open end of the drying chamber 1 and processing cylinder 2. The conveyor frame 3 rotates, causing it to carry the ceramic from the take-up area into the drying area. Hot air is generated by starting the hot air fan 6 and enters the drying area through the exhaust pipe 8 to dry the ceramic glaze. While drying, another ceramic can be placed on the rotating plate 5 of the take-up area. After drying, the conveyor frame 3 continues to rotate, carrying the ceramic into the drying area. In the cooling zone, the rotating plate 5 is controlled to rotate during the drying and cooling process of the ceramic glaze, which in turn drives the ceramic to rotate, allowing the ceramic to be more evenly subjected to the action of hot and cold air, which is beneficial to improving the quality of the ceramic. The ceramic in the pick-up zone continues to enter the drying zone for drying treatment, and the cold air fan 7 is activated to generate cold air to cool the ceramic in the cooling zone. The valves corresponding to the cooling zone are activated, and the hot and cold air in the cooling zone is discharged outward through the three-way pipe 111, so that the cold air flows in the cooling zone to improve the cooling efficiency. The ceramic after the cooling zone enters the pick-up zone for easy removal by the staff.

[0033] Before the ceramics enter the cooling zone from the drying zone, the hot air blower 6 is turned off and the exhaust fan 112 is started. The valve 114 on the connecting pipe 113 connected to the exhaust pipe 8 is opened. The exhaust fan 112 extracts the hot air in the drying zone for heat recovery and utilization. The hot air continues to heat the exhaust pipe 8 when it is discharged to prevent the temperature of the exhaust pipe 8 from dropping, so that the exhaust pipe 8 is kept at a high temperature to preheat the external air that is subsequently input.

[0034] like Figure 4 and Figure 5 As shown, in this embodiment, the limiting component 10 includes a fixed cylinder 101 that is fixed to the middle of the top surface of the rotating plate 5 by bolts, and a positioning frame 104 that is slidably installed in the fixed cylinder 101. The positioning frame 104 can move up and down along the inner wall of the fixed cylinder 101.

[0035] Four connecting rods 102 are movably passed through the side surface of the fixed cylinder 101. An arc-shaped limiting plate 103 is installed at the end of the connecting rod 102 away from the fixed cylinder 101. The limiting plates 103 are enclosed to form a ring.

[0036] The upper end of the positioning frame 104 moves through the top surface of the fixed cylinder 101, and the lower end of the positioning frame 104 moves into the inner side of the slot 107 opened on the top surface of the connecting rod 102. A pull plate 105 is installed on the top of the positioning frame 104, and the pull plate 105 is connected to the top surface of the fixed cylinder 101 by a spring 106.

[0037] The connecting rod 102 has several slots 107 that correspond to the lower end of the card holder 104, and the slots 107 on the connecting rod 102 are evenly distributed. The card holder 104 cooperates with different slots 107 to hold the connecting rod 102 in place.

[0038] Specifically, when it is necessary to limit the ceramic, the fixing cylinder 101 is fixed on the rotating plate 5 by bolts, and the clamping bracket 104 is moved upward and separated from the clamping groove 107 by pulling the pull plate 105 upward. At this time, the spring 106 receives the pulling force of the pull plate 105 and undergoes elastic deformation.

[0039] Then, pull the limiting plate 103, thereby changing the outer diameter of the ring formed by the various limiting plates 103 to correspond to the ceramic. Then, release the pulling force of the pull plate 105, and the positioning frame 104 moves downward into the corresponding slot 107 under the elastic force of the spring 106. At this time, the positions of the connecting rod 102 and the limiting plate 103 are fixed. The ceramic can then be placed on the rotating plate 5 with the ceramic opening facing down, so that the ceramic opening passes through the outer end of each limiting plate 103. The limiting plate 103 provides a limit for the ceramic, improving the stability of the ceramic conveying process.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
