[0002] A heat exchange structure needs to be set up in the mixing container, and the heat exchange structure is mostly a coil or a vertical cooling tube. Although the heat exchange effect of the traditional internal coil heat exchange structure can meet the requirements of most processes, the coil needs to be bent and coiled many times. When the medium bends and coils along the coil inside the coil, the flow rate will be reduced due to the long process, thereby reducing the heat exchange effect. In addition, the coil structure needs to have a fixed structure such as angle steel support, U-bolts, etc. installed inside the equipment. The structure is complex and the production is cumbersome. There are many dead angles between the support and the coil, and the material is easy to hang on the wall in the dead angle. A certain distance needs to be maintained between the coils, and the material will pass through the gap between the coils, so that the material cannot fully contact with the heat exchange medium, affecting the effect. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an inner heat exchange baffle of a stirring container to solve the problems of low heat exchange efficiency and insufficient stirring.

The horizontal direction of the heat exchange baffle is distributed along the radial direction of the barrel body and is close to the circumference of the barrel body. The vertical side surface of the heat exchange baffle close to the circumference of the barrel body is fixedly connected to the inner wall of the barrel body, and the heat exchange baffle is also connected to a water inlet pipe and a water outlet pipe.

[0005] As a preferred implementation scheme, positioning blocks for supporting are arranged in a matrix inside the cavity of the heat exchange baffle, and two ends of the positioning blocks are fixed on two opposite panels of the heat exchange baffle along the radial direction.

[0006] As a preferred embodiment, a gap is left between the vertical side of the heat exchange baffle close to the barrel body and the inner wall of the barrel body, a side of the heat exchange baffle in the same radial direction as the barrel body is fixed to the side edge of the horizontal rib plate, and multiple rib plates are evenly distributed along the vertical direction of the heat exchange baffle, and each rib plate is fixedly connected to the vertical side of the positioning plate close to the circumference of the barrel body, and the other vertical side of each positioning plate is fixed to the inner wall of the barrel body.

[0014] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0015] like Figure 1~Figure 3 The inner heat exchange baffle of the stirring container shown includes a vertical barrel body 1, a stirring device is arranged in the middle of the barrel body 1, and a plurality of rectangular heat exchange baffles 2 are evenly distributed on the circumference of the inner wall of the barrel body 1. The interior of the heat exchange baffle 2 is a flat cavity 7. The length direction of the heat exchange baffle 2 extends from the upper middle part to the bottom along the vertical inner wall of the barrel body 1. The horizontal direction of the heat exchange baffle 2 is distributed along the radial direction of the barrel body 1 and is close to the circumference of the barrel body 1. The vertical side surface of the heat exchange baffle 2 close to the circumference of the barrel body 1 is fixedly connected to the inner wall of the barrel body 1, and the heat exchange baffle 2 is also connected to a water inlet pipe 6 and a water outlet pipe 9.

[0016] Specifically, the heat exchange baffle 2 adopts the baffle shape on the inner barrel wall of the traditional agitator, which has a simple structure and has the functions of heat exchange and stirring. The cold flow medium in the heat exchange baffle 2 flows in from the water inlet pipe 6 and flows out from the water outlet pipe 9. The adjacent baffles in the flat and narrow cavity 7 are connected by pipelines. For different heat exchange areas, not only can the number of heat exchange baffles 2 be increased, but also the aspect ratio of the heat exchange baffle 2 can be changed to meet the heat exchange area, so that the contact surface between the material inside the barrel body 1 and the heat exchange baffle 2 is increased, and the heat exchange efficiency is high. During the process of the heat exchange baffle 2 stirring in the barrel body 1, the mixed material flows and hits the heat exchange baffle 2, which can also break the particles in the mixed material, so that the particle distribution is more uniform, improving the quality of the product, and pushing the material to the agitator rotating in the middle to fully mix the material and improve the mixing efficiency.

[0017] like Figure 3 The cavity 7 of the heat exchange baffle 2 is provided with a matrix of positioning blocks 3 for supporting purposes, and the two ends of the positioning blocks 3 are fixed on two opposite panels of the heat exchange baffle 2 in the radial direction. The heat exchange baffle 2 is welded into a rectangular hollow structure by splicing plates. The size of the internal gap is determined according to the flow rate of the internal cold flow medium, and the gap is controlled by the positioning blocks 3 inside, which can effectively ensure the gap is uniform. When the stirring equipment is running, a certain pressure is applied to the inside of the internal heat exchange baffle 2 to ensure that the flow rate of the internal medium is constant. Since the gap is small, the corresponding flow rate is fast, and the heat exchange effect of the material in contact with the heat exchange baffle 2 is significant.

[0018] There is a gap between the vertical side of the heat exchange baffle 2 close to the barrel body 1 and the inner wall of the barrel body 1. The side of the heat exchange baffle 2 in the same radial direction as the barrel body 1 is fixed to the side edge of the horizontal rib plate 4. Multiple rib plates 4 are evenly distributed along the vertical direction of the heat exchange baffle 2. Each rib plate 4 is fixedly connected to the vertical side of the positioning plate 8 near the circumference of the barrel body 1, and the other vertical side of each positioning plate 8 is fixed to the inner wall of the barrel body 1. This fixing method reduces the resistance of the heat exchange baffle 2 to the mixed flow of materials, so that the materials can flow fully.

[0019] Furthermore, four groups of heat exchange baffles 2 are evenly distributed on the inner circumference of the barrel body 1, each group includes two adjacent heat exchange baffles 2, the lower ends of the two heat exchange baffles 2 in each group are connected by a connecting pipe 5, the lower end of one heat exchange baffle 2 in each group is connected to a water inlet pipe 6, and the upper end of another heat exchange baffle 2 in each group is connected to a water outlet pipe 9. The water inlet pipe 6 is arranged at the lower end, and due to the effect of gravity, the fluid medium fills the interior of the heat exchange baffle 2 from bottom to top, and is discharged from the water outlet pipe 9 at the upper end after being filled, and the flow rate is stable and uniform, thereby increasing the utilization rate of heat.

[0020] The outer diameter of the positioning plate 8 in this embodiment is equal to the inner diameter of the stirring container, so that the positioning plate 8 can be matched with the inner wall of the stirring container. The side of the heat exchange baffle 2 in this embodiment away from the positioning plate 8 is inclined along the stirring direction in the stirring container, so that the side of the heat exchange baffle 2 facing away from the rib plate 4 is biased toward the center of the stirring container, so that the rotating fluid in the stirring container can be obliquely impacted on the side of the heat exchange baffle 2 facing away from the rib plate 4, and flow to the center of the stirring container under the guidance of the heat exchange baffle 2, and be stirred again.

[0021] The working process of the utility model is as follows:

[0022] According to Figures 1-3, first, the fluid medium is introduced into the water inlet pipe 6, the stirring device in the barrel body 1 of the water outlet pipe 9 is started, and then the material is poured into the barrel body 1, and finally, the stirring is completed.

[0023] The above embodiments are only illustrative of the principles and effects of the invention of the utility model, as well as some embodiments of its application, and are not intended to limit the invention of the utility model. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
