Description

Technical Field

[0001] The utility model relates to the technical field of toilet production, in particular to a tunnel kiln. Background Art

[0002] After the toilet body is sprayed with glaze, it needs to be sent to the tunnel kiln for baking. The high temperature will solidify the glaze and increase the durability and stability of the glaze layer.

[0003] In the related technology, a solution for an energy-saving tunnel kiln (Announcement No. CN210625312U) was found after searching. An air blockage and a product cooling device were added to the kiln tail so that the hot air in the kiln cooling section would not be lost through the kiln tail, but a slight positive pressure would be generated in the kiln cooling section, thereby blocking the heat energy of the calcining zone and reducing the heat energy loss of the calcining zone.

[0004] However, the above-mentioned tunnel kiln uses an induced draft fan to cool the toilet after baking. When the induced draft fan accelerates the natural temperature air to blow to the toilet, due to the complex internal structure of the toilet, the induced draft fan can only reduce the temperature of the surface of the toilet. After the toilet is transported out of the tunnel kiln, there are still local high-temperature areas that need to be cooled again, affecting the subsequent processing and assembly of the toilet. Utility Model Content

[0005] The purpose of the utility model is to provide a tunnel kiln to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a tunnel kiln, comprising a support plate, on which a preheating box, a high temperature box, and a cooling box are arranged, and two transverse air ducts are installed on the side of the cooling box, and the transverse air ducts are respectively connected to a first air supply fan and a first exhaust fan;

[0007] The first supply fan cooperates with the first exhaust fan to accelerate the air flow from the side of the toilet and quickly reduce the surface temperature of the toilet;

[0008] A longitudinal air duct is installed at the lower part of the side of the cooling box, and the longitudinal air duct is connected to a second blower. An exhaust duct is installed on the upper surface of the cooling box. The second blower blows air from bottom to top toward the toilet, which cools the toilet more comprehensively and accelerates the cooling of the toilet.

[0009] A third blower is installed on the upper wall of the cooling box, and an opening corresponding to the third blower is provided on the surface of the cooling box. A fixing ring is provided on the surface of the third blower, and a plurality of spray heads are plugged on the surface of the fixing ring, and the plurality of spray heads are interconnected and arranged in a ring shape;

[0010] The third blower blows the water mist toward the toilet, and the residual heat of the toilet evaporates the water mist. The evaporation of the water mist can absorb the residual heat of the toilet, and the toilet can be processed later after coming out of the tunnel kiln.

[0011] Furthermore, the upper surfaces of the preheating box and the high temperature box are respectively provided with a first collecting pipe and a second collecting pipe, and the first collecting pipe and the second collecting pipe are connected to discharge the waste gas in the preheating box and the high temperature box, and also utilize the waste heat of the high temperature box.

[0012] Furthermore, a filter is provided on the upper surface of the cooling box, and the filter is located above the third air supply fan. The filter can block dust and particles from entering the cooling box, thereby preventing dust and particles from being on the toilet when cooling the toilet.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Water can be atomized through the circularly arranged spray heads. When the third blower rotates, the water mist is blown to all parts of the toilet to achieve a uniform cooling effect. The water mist absorbs the waste heat of the toilet. When the waste heat of the toilet evaporates the water mist, the water mist evaporates and absorbs heat, which can quickly lower the temperature of the toilet and reduce the residual water stains on the toilet, making it easier for the subsequent processing and assembly of the toilet, and helping to improve the production efficiency of the toilet.

[0015] (2) The first blower and the first exhaust blower allow air to flow horizontally in the cooling box, and the second blower allows air to flow vertically in the cooling box. When the toilet passes through the horizontal wind and the vertical wind, the toilet is fully cooled by blowing air, which makes the heat dissipation more uniform, prevents local high temperature in the toilet, and is beneficial to the production of toilets.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-5 The utility model provides a technical solution: a tunnel kiln, comprising a support plate 1, on which a preheating box 4, a high temperature box 8, and a cooling box 16 are arranged, and two transverse air ducts 11 are installed on the side of the cooling box 16, and the transverse air ducts 11 are respectively connected to a first air supply fan 9 and a first exhaust fan 10, and the first air supply fan 9 and the first exhaust fan 10 can accelerate the rapid flow of air in the cooling box 16, and the cooling efficiency of the toilet is high;

[0025] The preheating box 4 preheats the toilet body sprayed with glaze to prevent the toilet body from cracking due to high temperature. The preheated toilet body enters the high temperature box 8 for baking, which can make the glaze better adhere to the surface of the toilet body. Some odors and harmful gases may be generated during the glazing process. Baking can help release these gases, making the toilet safer and harmless. The cooling box 16 cools the toilet to avoid scalding problems and facilitate the subsequent processing of the toilet.

[0026] A longitudinal air duct 20 is installed at the lower part of the side of the cooling box 16, and the longitudinal air duct 20 is connected to the second blower 13. An exhaust duct 12 is installed on the upper surface of the cooling box 16. The second blower 13 blows air from bottom to top through the longitudinal air duct 20 to the toilet to fully dissipate heat from the toilet.

[0027] A third blower 18 is installed on the upper wall of the cooling box 16, and an opening corresponding to the third blower 18 is provided on the surface of the cooling box 16. A fixing ring 19 is provided on the surface of the third blower 18. A plurality of spray heads 14 are plugged on the surface of the fixing ring 19, and the plurality of spray heads 14 are interconnected and arranged in a ring shape.

[0028] The third blower 18 can blow air and water mist toward the toilet, perform double heat dissipation on the toilet, and quickly reduce the temperature of the toilet.

[0029] In this embodiment, if Figure 1 As shown, a guide rail 2 is provided on the surface of the support plate 1, and a feeding trolley 3 is provided on the guide rail 2. The feeding trolley 3 moves along the guide rail 2, and the toilet is placed on the feeding trolley 3, and the feeding trolley 3 transports the toilet to the inside of the tunnel kiln.

[0030] In this embodiment, if Figure 1 As shown, the upper surfaces of the preheating box 4 and the high temperature box 8 are respectively provided with a first collecting pipe 21 and a second collecting pipe 5, and the first collecting pipe 21 and the second collecting pipe 5 are connected, and the exhaust gas in the preheating box 4 and the high temperature box 8 is exhausted through the first collecting pipe 21 and the second collecting pipe 5, ensuring that the high temperature box 8 can smoothly maintain a high temperature state, and the preheated exhaust gas can be reused.

[0031] In this embodiment, if Figure 1 As shown, a burner 7 is installed on the surface of the high temperature box 8, and a combustion-supporting air duct 6 is connected to the burner 7. The combustible gas is ignited and ejected through the burner 7. The combustion-supporting air duct 6 provides oxygen for combustion to ensure that the burner 7 bakes the toilet.

[0032] In this embodiment, if Figure 4 As shown, a filter 17 is provided on the upper surface of the cooling box 16, and the filter 17 is located above the third air blower 18. The filter 17 filters some dust and particles to prevent the third air blower 18 from extracting dust and particles, thereby preventing dust and particles from being on the toilet.

[0033] In this embodiment, if Figure 1 As shown, two second exhaust fans 15 are installed on the right side of the upper surface of the cooling box 16. The second exhaust fans 15 draw air, and when the air flows through the toilet, the toilet is dried and cooled.

[0034] Specifically, when in use, the toilet body sprayed with glaze is placed on the feeding cart 3, and the feeding cart 3 sends the toilet body to the preheating box 4 for preheating. The preheated toilet body is then sent to the high-temperature box 8 by the feeding cart 3 for baking. The combustion of the burner 7 can generate a high temperature to burn the toilet body, so that the glaze can form a more solid protective layer, thereby improving the strength and wear resistance of the toilet. Then the feeding cart 3 sends the toilet to the cooling box 16, and the first blower 9 and the first exhaust fan 10 make the air flow horizontally at high speed in the cooling box 16, and the second blower 13 makes the air flow from bottom to top through the longitudinal air duct 20. When the toilet When the wind blows in the horizontal and vertical directions, the toilet is fully blown to dissipate heat. When the toilet moves to the bottom of the third blower 18, high-pressure water forms water mist through the spray head 14. When the third blower 18 rotates, the water mist is sent to various parts of the toilet through the fast-flowing air. The water mist falls on the toilet and absorbs the residual heat of the toilet. The residual heat of the toilet can also evaporate the water mist, reducing the residual water mist on the toilet. The toilet moves to the bottom of the second exhaust fan 15. The second exhaust fan 15 allows air to flow over the toilet, dissipating the heat of the toilet and removing the water mist again. The temperature of the toilet coming out of the cooling box 16 will not be too high, which is convenient for processing and assembly.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
