[0031] Embodiment 1

[0032] Referring to Figure 1 As shown, an embodiment of the present application provides a conveying device 100, which includes a conveying frame 110 and a heating assembly 120.

[0033] Combining Figure 2 and Figure 4As shown, a plurality of conveying rollers 111 are arranged side by side on the conveying frame 110, and a gap 112 is formed between two adjacent conveying rollers 111; the heating assembly 120 is arranged in the gap 112, and the heating assembly 120 includes a burner 121 and a flame guiding member 122. The flame guiding member 122 is connected to the burner 121, and a fire outlet 1223 is arranged at one end of the flame guiding member 122 away from the burner 121. From the nozzle of the burner 121 to the fire outlet 1223, the cross-sectional area of the flame guiding member 122 gradually increases. Correspondingly, the conveying rollers 111 on the conveying frame 110 are used to convey the glaze body. The heating assembly 120 can be installed at the position of the gap 112, and the glaze body can be heated during the process of the glaze body being conveyed on the conveying rollers 111. The burner 121 of the heating assembly 120 is used to heat the glaze body, reduce the moisture contained in the glaze body, keep the glaze body in a dry state, and prevent the influence caused by the formation of rod nails in the glaze body. The flame guiding member 122 can guide the flame of the burner 121, reduce the situation of the flame spreading everywhere, and improve the heating efficiency. From the nozzle of the burner 121 to the fire outlet 1223, the cross-sectional area of the flame guiding member 122 gradually increases to increase the roasting range of the flame through the flame guiding member 122.

[0034] It can be understood that the conveying rollers 111 are used to automatically convey the glaze body on the production line, and the kiln is used to fire the glaze body. Therefore, it is necessary to control the moisture standard contained in the glaze body before entering the kiln to prevent the glaze body from forming rod nails on the conveying rollers 111 during firing in the kiln, which will affect the subsequent use of the conveying rollers 111.

[0035] Reference Figures 1 to 3 As shown, the conveying device 100 has a first direction and a second direction, and the first direction and the second direction are arranged at an angle. Exemplarily, the first direction takes the conveying direction of the conveying device 100 as an example, and the second direction takes the axial direction of the conveying rollers 111 of the conveying device 100 as an example, and the first direction and the second direction are perpendicular to each other.

[0036] In one embodiment, optionally, in combination with Figure 2 and Figure 4 As shown, the flame guiding member 122 includes a first flame guiding plate 1221 and a second flame guiding plate 1222. The first flame guiding plate 1221 and the second flame guiding plate 1222 are both installed at the nozzle position of the burner 121, and the first flame guiding plate 1221 and the second flame guiding plate 1222 are arranged at an angle, that is, the first flame guiding plate 1221 and the second flame guiding plate 1222 can form a flame guiding channel, which is convenient for guiding the flame generated by the nozzle of the burner 121 through the flame guiding channel, increasing the contact area of the flame, and enabling the flame to heat and dry the glaze body passing on the conveying rollers 111 to reduce the moisture contained in the glaze body.

[0037] Optionally, as Figure 2 shown, both the first flame guiding plate 1221 and the second flame guiding plate 1222 are arranged along the axial direction of the conveying roller 111, that is, the first flame guiding plate 1221 and the second flame guiding plate 1222 are arranged along the second direction, and the arrangement directions of the first flame guiding plate 1221 and the second flame guiding plate 1222 are perpendicular to the conveying direction of the conveying roller 111. When multiple glaze bodies are conveyed through the conveying roller 111 in sequence, they can be heated and dried respectively, without affecting the normal transmission of the glaze bodies on the conveying roller 111, and the glaze bodies do not need to stop on the conveying roller 111 for heating and drying.

[0038] In one embodiment, optionally, referring to Figure 3 shown, the number of the heating components 120 is multiple, and along the conveying direction of the conveying roller 111, the multiple heating components 120 are arranged in parallel. In other words, the multiple heating components 120 are arranged in parallel along the first direction, so that during the transmission of the glaze bodies on the conveying roller 111, the multiple heating components 120 heat and dry the glaze bodies in sequence, improving the drying effect. The number of the heating components 120 can be set as required according to the actual drying effect of the glaze bodies. It can be understood that the heating component 120 refers to a component that can generate heat energy through electricity, fuel oil, gas, etc. and transfer it to the working medium. Exemplarily, the heating component 120 can be one of a liquid fuel burner or a gas fuel burner.

[0039] In summary, on the conveying device 100, the conveying roller 111 on the conveying frame 110 is used to convey the glaze bodies, the heating component 120 can be installed at the position of the gap 112, and the glaze bodies can be heated during the transmission of the glaze bodies on the conveying roller 111. The burner 121 of the heating component 120 is used to heat the glaze bodies, reduce the moisture contained in the glaze bodies, keep the glaze bodies in a dry state, prevent the influence caused by the formation of rod nails of the glaze bodies, the flame guiding member 122 can guide the flame of the burner 121, reduce the situation of the flame spreading everywhere, improve the heating efficiency, from the nozzle of the burner 121 to the fire outlet 1223, the cross-sectional area of the flame guiding member 122 gradually increases to facilitate increasing the roasting range of the flame through the flame guiding member 122, reduce the product defect rate, and thus improve the product quality.

[0040] Embodiment 2

[0041] Referring to Figure 1 shown, an embodiment of the present application provides another conveying device 100, and this conveying device 100 includes a conveying frame 110 and a heating component 120.

[0042] As Figure 3As shown, a plurality of conveying rollers 111 are arranged side by side on the conveying frame 110, and a gap 112 is formed between two adjacent conveying rollers 111. The conveying rollers 111 on the conveying frame 110 are used for conveying the glaze body, and the shape or size of the conveying frame 110 is not specifically limited herein.

[0043] In this embodiment, in combination with Figure 2 and Figure 4 As shown, the heating assembly 120 is disposed in the gap 112. The heating assembly 120 includes a burner 121 and a flame guiding member 122. The flame guiding member 122 is connected to the burner 121. An outlet 1223 is provided at one end of the flame guiding member 122 away from the burner 121. From the nozzle of the burner 121 to the outlet 1223, the cross-sectional area of the flame guiding member 122 gradually increases. In other words, the heating assembly 120 can be installed at the position of the gap 112, and the glaze body can be heated during the transmission of the glaze body on the conveying rollers 111. The burner 121 of the heating assembly 120 is used to heat the glaze body, reduce the moisture contained in the glaze body, keep the glaze body in a dry state, and prevent the influence caused by the formation of rod nails in the glaze body. The flame guiding member 122 can guide the flame of the burner 121, reduce the situation of the flame spreading everywhere, and improve the heating efficiency. From the nozzle of the burner 121 to the outlet 1223, the cross-sectional area of the flame guiding member 122 gradually increases to increase the roasting range of the flame through the flame guiding member 122.

[0044] Exemplarily, two adjacent conveying rollers 111 can be connected by a rotating bearing 114, and the rotating bearing 114 can reduce friction and ensure the normal rotation of the conveying rollers 111.

[0045] Referring to Figures 1 to 3 As shown, the conveying device 100 has a first direction and a second direction, and the first direction and the second direction are arranged at an angle. Exemplarily, the first direction takes the conveying direction of the conveying device 100 as an example, and the second direction takes the axial direction of the conveying rollers 111 of the conveying device 100 as an example, and the first direction and the second direction are perpendicular to each other. It can be understood that the above definitions are only for facilitating the understanding of the relative position relationship of each part in the conveying device 100, and should not be construed as a limitation to the present application.

[0046] In one embodiment, optionally, in combination with Figure 2 and Figure 4As shown, the flame guiding member 122 includes a first flame guiding plate 1221 and a second flame guiding plate 1222. Both the first flame guiding plate 1221 and the second flame guiding plate 1222 are installed at the nozzle position of the burner 121, and the first flame guiding plate 1221 and the second flame guiding plate 1222 are arranged at an angle, that is, the first flame guiding plate 1221 and the second flame guiding plate 1222 can form a flame guiding channel, facilitating the guiding of the flame generated by the nozzle of the burner 121 through the flame guiding channel, increasing the contact area of the flame, and enabling the flame to heat and dry the glaze passing on the conveying roller 111 to reduce the moisture content in the glaze. Exemplarily, the material of the flame guiding member can be selected from one of nickel alloy, alloy steel, and stainless steel.

[0047] Optionally, the included angle between the first flame guiding plate 1221 and the second flame guiding plate 1222 is θ, satisfying 40° ≤ θ ≤ 80°, that is, the included angle between the first flame guiding plate 1221 and the second flame guiding plate 1222 gives the flame guiding member 122 a certain flame guiding range, which is beneficial for heating and drying the glaze on the conveying roller 111. Exemplarily, θ is 80°. At this time, the included angle between the first flame guiding plate 1221 and the second flame guiding plate 1222 is 80°, giving the flame guiding member 122 a larger flame guiding angle, so that the flame and the glaze to be heated have a sufficient contact area. Additionally, θ can also be 40°, which can make the flame of the flame guiding member 122 more concentrated, have a higher heating temperature, improve the heating effect, and more quickly reduce the water content of the glaze. Of course, the angle of θ is not limited to this. In other embodiments, when θ is 45°, 50°, 60°, 65°, 70°, 75°, etc., they will not be listed one by one here.

[0048] Optionally, as Figure 3 shown, both the first flame guiding plate 1221 and the second flame guiding plate 1222 are arranged along the axial direction of the conveying roller 111, that is, the first flame guiding plate 1221 and the second flame guiding plate 1222 are arranged along the second direction, and the arrangement direction of the first flame guiding plate 1221 and the second flame guiding plate 1222 is perpendicular to the conveying direction of the conveying roller 111. When multiple glazes are sequentially conveyed through the conveying roller 111, they can be heated and dried respectively without affecting the normal transmission of the glazes on the conveying roller 111, and the glazes do not need to stop on the conveying roller 111 for heating and drying. Exemplarily, the first flame guiding plate 1221 and the second flame guiding plate 1222 can be welded to the nozzle position of the burner 121.

[0049] In one embodiment, optionally, referring to Figure 3As shown, the number of the heating components 120 is multiple. Along the conveying direction of the conveying roller 111, the multiple heating components 120 are arranged in parallel. In other words, the multiple heating components 120 are arranged in parallel along the first direction. When the glaze body is being conveyed on the conveying roller 111, the glaze body is heated and dried successively by the multiple heating components 120, improving the drying effect. The number of the heating components 120 can be set as required according to the actual drying effect of the glaze body. Exemplarily, the number of the heating components 120 is two, and when the glaze body passes above the two heating components 120 successively during the conveying process, the glaze body is heated and dried.

[0050] Optionally, one heating component 120 corresponds to one gap 112. The position of the heating component 120 can be set within the gap 112, and it will not obstruct or affect the conveyance of the glaze body on the conveying roller 111.

[0051] In one embodiment, optionally, the height of the flame guiding member 122 is h1, the top height of the conveying roller 111 is h2, and the height of the conveying rack 110 is h3, satisfying: h3 ≤ h1 ≤ h2, that is, the height h1 of the flame guiding member 122 is greater than or equal to the height h3 of the conveying rack 110, enabling the flame guiding member 122 to guide the direction and range of the flame, preventing the flame guiding member 122 from being too far away from the glaze body and affecting the heating and drying of the glaze body. At the same time, the height h1 of the flame guiding member 122 is less than or equal to the top height h2 of the conveying roller 111. When the glaze body is being conveyed along the conveying roller 111, the height h1 of the flame guiding member 122 will not obstruct or affect the conveyance of the glaze body, ensuring the normal conveyance effect of the glaze body, and also being able to heat and dry the glaze body to reduce the water content of the glaze body.

[0052] Based on any of the above embodiments, optionally, as Figure 2 shown, the conveying rack 110 further includes a support platform 113. The support platform 113 is installed on the conveying rack 110 and is arranged corresponding to the position of the gap 112, so that one side of the burner 121 facing away from the flame guiding member 122 is connected to the support platform 113. The burner 121 can be installed on the support platform 113, and the burner 121 can generate a flame, and the flame is guided and concentrated by the flame guiding member 122. Exemplarily, the number of the support platforms 113 can be multiple, and one support platform 113 corresponds to one burner 121.

[0053] Based on any of the above embodiments, optionally, as Figure 3As shown, the conveying device 100 further includes a gas conveying member 130.
