[0036] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0037] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.
[0038] In the production of tire base fabric, the quality of the tire base fabric dipping process directly affects the performance and quality of the final product. The glue mixing process is an important link that determines the dipping process, because it directly affects the uniformity, viscosity and temperature control of the glue, and other key parameters.
[0039] At present, the commonly used heating method for glue mixing is to make a jacket or coil outside the glue mixing kettle, and high-temperature heat transfer oil or high-temperature steam is introduced into the jacket or coil to heat the glue mixing kettle. When the high-temperature heat transfer oil or high-temperature steam is heated, it is transported into the jacket or coil. Inside the jacket or coil, heat is transferred to the outer wall of the glue mixing kettle by conduction and convection, and then transferred to the glue by heat conduction. In this way, the glue can be uniformly heated, so as to realize the mixing, melting and molding process of the glue.
[0040] For the related technology in the above, the inventor believes that the heating mode of the jacket or coil located outside the glue mixing kettle is complicated in the transmission process, which causes slow heat conduction speed, long heating time, and continuous temperature rise due to the influence of high-temperature medium residual heat, so that the heating temperature is not easy to accurately control, which ultimately affects the glue mixing quality.
[0041] In order to quickly heat the medium inside the glue mixing kettle and accurately control the temperature inside the glue mixing kettle, the application provides a tire base fabric glue mixing kettle heating system.
[0042] The following will be combined with the drawings Figures 1-5 Further details of the application will be described.
[0043] The application embodiment discloses a tire base fabric glue mixing kettle heating system. Referring to Figure 1 、 Figure 2 A tire base fabric glue mixing kettle heating system includes a glue mixing kettle 1, a steam assembly 2 is arranged inside the glue mixing kettle 1, the steam assembly 2 is used to provide steam to the inside of the glue mixing kettle 1, and then control the temperature of the medium located inside the glue mixing kettle 1. An auxiliary heat preservation assembly 3 is sleeved on the outside of the glue mixing kettle 1, the auxiliary heat preservation assembly 3 is in opposite communication with the steam assembly 2, and a temperature adjusting assembly is arranged on the glue mixing kettle 1, which can control the steam flow entering the inside of the steam assembly 2 and the auxiliary heat preservation assembly 3. A steam circulation pipeline 4 is arranged on one side of the glue mixing kettle 1, which circulates the condensed water generated on the outside of the glue mixing kettle 1, and the condensed water after circulation forms steam and is re-injected into the inside of the steam assembly 2 for circulating heating.
[0044] Referring to Figure 2 、 Figure 3 , the steam assembly 2 includes a vertically arranged steam pipe 21, which extends into the inside of the glue mixing kettle 1 from the top end of the glue mixing kettle 1. A steam hole 22 is formed in the side wall of the steam pipe 21, which is in opposite communication with the inside of the glue mixing kettle 1 through the steam hole 22, so as to inject the steam in the steam pipe 21 into the glue mixing kettle 1 from the position of the steam hole 22, and heat the medium in the glue mixing kettle 1.
[0045] The steam pipe 21 includes an air inlet portion 211 located in the upper part of the glue mixing kettle 1, an air outlet portion 212 fixedly connected to the bottom end of the air inlet portion 211, the air inlet portion 211 and the air outlet portion 212 are in opposite communication, and the steam hole 22 is formed on the air outlet portion 212, so that the steam in the air inlet portion 211 can enter the inside of the air outlet portion 212, and enter the inside of the glue mixing kettle 1 through the steam hole 22 on the air outlet portion 212.
[0046] In some embodiments, the air outlet 212 is a hollow tubular structure coaxially arranged with the air inlet 211, and the steam holes 22 are arranged on one side of the air outlet 212 close to the axis direction of the glue mixing kettle 1, and a plurality of steam holes 22 are arranged along the axis direction of the air outlet 212.
[0047] Referring to Figure 3 In some other embodiments, the air outlet 212 is a steam disc 23 fixed at the bottom end of the air inlet 211, the steam disc 23 is horizontally arranged, the steam disc 23 is a disc structure or other structure suitable for the inner side wall of the glue mixing kettle 1, the top wall area of the steam disc 23 is larger than the diameter of the air inlet 211, the axis of the steam disc 23 is coaxially arranged with the axis of the glue mixing kettle 1, and one side of the steam disc 23 is fixedly connected with the air inlet 211. The inside of the steam disc 23 is a hollow structure, and the inside of the steam disc 23 is in communication with the inside of the air inlet 211. The steam holes 22 are arranged on the top wall of the steam disc 23, and a plurality of steam holes 22 are arranged on the top wall of the steam disc 23.
[0048] Referring to Figure 4 , Figure 5 In some other embodiments, the air outlet 212 is a steam shell 24 fixed at the bottom end of the air inlet 211, the steam shell 24 is a hollow rectangular structure, and the side wall of the steam shell 24 is horizontally provided with a medium flow channel 241, the medium flow channel 241 is arranged along the medium flow direction inside the glue mixing kettle 1, and the medium flow channel 241 penetrates the side wall of the steam shell 24 completely, the medium inside the glue mixing kettle 1 can enter the inside of the medium flow channel 241 from the side of the steam shell 24 facing the water surface, and flow out from the side of the steam shell 24 away from the water surface after flowing in the inside of the medium flow channel 241.
[0049] One side of the side wall of the steam shell 24 relative to the medium flow channel 241 forms a medium flow plate 242, and the steam holes 22 are arranged on the medium flow plate 242, so that the steam inside the steam shell 24 can enter the medium flow channel 241 through the steam holes 22 to heat the medium inside the medium flow channel 241.
[0050] The cross-sectional area of the medium flow channel 241 gradually decreases from the side close to the water surface of the steam shell 24 to the side away from the water surface of the steam shell 24, so that the medium flowing in the inside of the medium flow channel 241 is pressurized under the condition of decreasing cross-sectional area, and the flow speed in the inside of the medium flow channel 241 is further accelerated. The flow speed of the medium outside the steam holes 22 is greater than the flow speed of the steam inside the steam holes 22, so that the steam inside the steam holes 22 is driven out to the inside of the medium flow channel 241 to heat the medium inside the medium flow channel 241.
[0051] In order to reduce the amount of medium inside the medium flow channel 241 entering the steam shell 24 through the steam hole 22, the medium flow plate 242 includes a water-facing part 2421 located on the side of the steam hole 22 near the water-facing surface of the steam shell 24 and a back-water part 2422 located on the side away from the water-facing surface. The water-facing part 2421 and the back-water part 2422 are fixedly connected, and the water-facing part 2421 and the back-water part 2422 have the same inclination angle. The water-facing part 2421 is located on the side of the back-water part 2422 near the center of the medium flow channel 241.
[0052] This ensures that the medium inside the medium flow channel 241, guided by the water-facing part 2421, flows in a direction opposite to that of the steam hole 22, reducing the possibility of the medium inside the medium flow channel 241 entering the steam hole 22 and causing blockage of the steam pipe 21.
