Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, specifically relating to a high-temperature, high-viscosity material cooling feeder. Background Technology

[0002] In the rubber processing industry, rubber powder and additives are thoroughly mixed in a high-speed mixer. During the mixing process, the material temperature rises significantly due to frictional heat generation and exothermic chemical reactions. These high-temperature, high-viscosity materials need to be cooled before being transported to downstream extruders, reactors, and other equipment to ensure continuous production. Current technology requires separate cooling mixers and feeders, which occupy large spaces and incur high investment costs. Due to the high material temperature and poor flowability, agglomeration and blockage are prone to occur, and uneven heat dissipation due to localized material accumulation can easily lead to smoldering without an open flame. Therefore, there is an urgent need for a compact, space-saving cooling feeder that can effectively replace traditional cooling mixers and conventional feeding devices, integrating mixing, cooling, and conveying functions into one unit for high-temperature, high-viscosity materials.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figures 1 to 3As shown, a high-temperature, high-viscosity material cooling feeder includes a horizontal hopper 1, a spiral agitator 2, and a screw conveyor 3. The horizontal hopper has a large-capacity structure to buffer the high-temperature, high-viscosity material output from upstream equipment. The spiral agitator is rotatably connected inside the horizontal hopper to agitate the material, break up agglomeration, and push it towards the discharge port. Simultaneously, it continuously turns the material to prevent local accumulation, improve natural heat dissipation efficiency, and suppress smoldering. A temperature sensor 17 (thermocouple temperature sensor) is installed at the end of the horizontal hopper near the discharge port to facilitate the detection of the material temperature inside the hopper. The spiral agitator includes a shaft body 201, with spiral agitator blades 202 at one end and at least two spaced scraper blades 203 at the other end. The scraper blades are located directly above the discharge port and have a T-shaped structure. They can scrape away material from the inner wall of the horizontal hopper, reducing material residue and preventing material accumulation at the discharge port. A feed inlet 4 and a first power device 5, such as a geared motor, are provided on one side of the horizontal hopper to drive the spiral agitator shaft. The screw conveyor is located below the horizontal hopper, and its upper inlet 6 is connected to the outlet 7 located on the lower part of the other side of the horizontal hopper. Figure 4 As shown, the screw conveyor includes a housing 301. Inside the housing are two parallel screw shafts 302. Outside the housing is a second power unit 303, such as a geared motor, for driving the two screw shafts to rotate in the same direction, used for quantitatively conveying materials to downstream equipment. The output shaft of the second power unit is connected to a drive gear, which meshes with driven gears respectively connected to the two screw shafts (this meshing transmission structure is prior art and will not be described further here; it is not shown in the figure), thereby achieving synchronous rotation of both in the same direction.

[0021] like Figures 1 to 4 As shown, the bottom of the screw conveyor is equipped with a support base 8, and below the support base is a base plate 9. A weighing sensor 10 is installed between the support base and the base plate to monitor the overall weight change (i.e., relative weight) of the feeder in real time. The weighing sensor is located on the side of the base plate near the discharge end of the screw conveyor. The other end of the support base rests on the base plate, and a leveling mechanism for adjusting the horizontality is provided between the support base and the base plate. Figure 5As shown, the leveling mechanism includes a support bolt 11 threaded to the support seat, a nut 12 threaded to the support bolt, and a support groove 13 located on the top of the base plate. The bottom end of the support bolt rests in the support groove, and the nut is located above the support seat, facilitating the adjustment of the entire feeder to a horizontal state and providing a stable foundation for high-precision metering. The weighing sensor, temperature sensor, first power unit, and second power unit are all electrically connected to the feeder's control system (not shown in the figure). The weighing sensor measures the material weight change in real time and feeds it back to the control system. The temperature sensor measures the internal temperature in real time and feeds it back to the control system. The control system regulates the rotation speed of the ribbon stirring shaft and the two spiral shafts to achieve continuous, stable, and quantitative material conveying, ensuring safe, stable, and accurate equipment operation. This is existing technology and will not be described in detail further.

[0022] like Figure 1 and Figure 2 As shown, the horizontal hopper is also equipped with an emergency discharge port 14, which is bolted to a cover plate and is located on one side of the discharge port. If the material temperature inside the horizontal hopper becomes too high due to operator error or other factors, resulting in internal smoldering, the emergency discharge port can be opened for rapid discharge. The upper part of the horizontal hopper is equipped with at least one water inlet 15. In this embodiment, combined with... Figure 2 As shown, there are two water inlets to facilitate the flow of water into the horizontal hopper, enabling rapid cooling and eliminating the risk of smoldering. In addition, the upper part of the horizontal hopper is equipped with an exhaust port 16, which is connected to environmental protection equipment to reduce the emission of harmful gases.

[0023] The working process of this utility model is as follows: The high-temperature, high-viscosity material output from the upstream high-speed mixer enters the horizontal hopper 1 directly through the feed inlet 4 for buffering. The volume design of the horizontal hopper 1 ensures that the material will not accumulate excessively. The first power unit 5 drives the spiral ribbon stirring shaft 2 to rotate. During its rotation, the spiral ribbon stirring blades 202 and scraper blades 203 agitate the material in all directions, breaking up any agglomeration. At the same time, the material is continuously turned over to prevent prolonged local stagnation. During the horizontal pushing process, the material fully contacts the inner wall of the horizontal hopper 1, achieving efficient natural heat dissipation, rapidly reducing the temperature, and suppressing the risk of smoldering. The material continuously enters the screw conveyor device 3 through the feed inlet 6 from the discharge outlet 7. The screw conveyor device 3, based on the preset conveying capacity of the control system and combined with the real-time monitoring of material weight changes by the weighing sensor, drives two parallel spiral shafts 302 to rotate synchronously and in the same direction, achieving continuous quantitative conveying of material to the downstream equipment.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
