Description

Technical Field

[0001] The present application relates to the technical field of cooling equipment, and in particular to an elastic particle mixing cooling device. Background Art

[0002] The temperature of elastic granules is often relatively high after production. In order to prevent the elastic granules from damaging the packaging bags, they need to be cooled before packaging. The current common cooling method is static cooling. Due to the relatively low thermal conductivity of elastic granules, the outer temperature of the elastic granules stacked together is usually relatively low, but the temperature of the granules in the center is still relatively high. It is difficult to perform stable detection on the center of the stacked elastic granules, so it takes a long time to cool all the elastic granules, which may affect subsequent operation steps.

[0005] Preferably, the lower cover includes a tray, the upper surface of the tray has an embedded disk, which is suitable for fitting with the discharge port. After fitting, the upper surface of the embedded disk is flush with the upper surface of the base, so that the inner bottom surface of the cooling tank with the lower end closed is flat, so that the particles in the center can be fully exchanged with the particles at the edge.

The hydraulic cylinder includes a matching cylinder barrel and a telescopic rod, and the cylinder barrel is rotatably connected to the first hinged frame, and the telescopic rod is rotatably connected to the second hinged frame, so that the telescopic movement of the hydraulic cylinder can be converted into the rotational movement of the lower cover.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) By rationally designing the liquid cooling components and stirring mechanism, while accelerating the heat dissipation, the particles in the center of the elastic particle pile are exchanged with the particles on the periphery, converting the heat dissipation of the particles by heat conduction into heat convection, which has higher heat dissipation efficiency and faster cooling rate;

Therefore, the cooling device can also perform special low-temperature treatment on the mixed elastic particles, reducing the volume of the elastic particles and occupying less space when packaged. After returning to normal temperature, the elastic particles will automatically burst out when the package is opened. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.

[0028] like Figure 1-8 The elastic particle mixing cooling device shown includes a vertically placed cooling tank 2, which has a double-layer structure of a heat-insulating shell 203 and a heat-conducting tube 204. The heat-insulating shell 203 is made of a non-metallic material with relatively low thermal conductivity, such as plastic or wood, and the heat-conducting tube 204 is made of an alloy material with relatively high thermal conductivity. The heat-insulating shell 203 also has a double-layer structure, which will have a better heat insulation effect. The geometric center lines of the heat-insulating shell 203 and the heat-conducting tube 204 are collinear, and the outer diameter of the heat-conducting tube 204 is smaller than the inner diameter of the heat-insulating shell 203. Therefore, a configuration cavity 205 is formed between the inner wall of the heat-insulating shell 203 and the outer side surface of the heat-conducting tube 204. The cooling tank 2 is provided with a cooling pipe 220 in the configuration cavity 205. The cooling pipe 220 is made of a corrosion-resistant alloy material. The heat preservation shell 203 and the heat-conducting tube 204 are fixedly connected to the base 210 for limiting the relative position relationship between the heat preservation shell 203 and the lower end of the heat-conducting tube 204. The base 210 is provided with a through hole 214 connecting the configuration cavity 205 with the outside for the two ends of the cooling tube 220 to pass through. One end of the cooling tube 220 is provided with a liquid inlet end 221 and the other end is provided with a liquid discharge end 222. The liquid inlet end 221 and the liquid discharge end 222 are connected to the heat dissipation circulation equipment outside the cooling device, thereby realizing heat transfer and recycling of the cooling medium.

[0029] The base 210 is provided with a discharge port 211 which passes through the upper and lower end surfaces, from which the cooled elastic mixed shell is discharged. The bottom surface of the base 210 is rotatably connected to the lower cover 4 for blocking the discharge port 211. The lower surface of the base 210 is fixedly connected to a first hinge frame 213 extending downward. A hydraulic cylinder 3 is movably connected between the first hinge frame 213 and the lower cover 4 for driving the lower cover 4 to rotate relative to the base 210. The specific structure of the lower cover 4 includes a tray 401, a tray 40 1 has a diameter larger than the discharge port 211 and can only be located below the base 210. The lower cover 4 is rotatably connected to the first hinge frame 213. In fact, the side of the tray 401 has a hinge plate 403, which is rotatably connected to the upper end of the first hinge frame 213, and the lower surface of the tray 401 is also fixedly connected to the second hinge frame 404. The hydraulic cylinder 3 includes a matching cylinder 301 and a telescopic rod 302, wherein the lower end of the cylinder 301 is rotatably connected to the first hinge frame 213. When the hydraulic cylinder 3 is extended or retracted, the inclination angle of the lower cover 4 relative to the base 210 will change. The upper surface of the tray 401 has an embedded plate 402, which fits exactly with the discharge port 211, and after the fit, the upper surface of the embedded plate 402 is flush with the upper surface of the base 210. That is to say, when the lower cover 4 is closed, the inner bottom surface of the cooling tank 2 is a plane, and the rolling resistance of the particles during stirring is smaller. The lower surface of the base 210 has a reinforcing ring 212, which can improve the structural strength of the base 210. The reinforcing ring 212 is disconnected at the first hinge frame 213 to make way for the rotatable hinge plate 403. When the tray 401 is rotated to the horizontal position, it is just embedded in the reinforcing ring 212, forming a stepped structure, which can effectively prevent the elastic particles from leaking out. The lower surface of the base 210 is also fixedly connected to the support 1, so that the base 210 is suspended a certain height from the placement surface, thereby reserving sufficient space for the lower cover 4 to move.

[0030] The upper ends of the insulation shell 203 and the heat-conducting tube 204 are fixedly connected to the frame 5 through the sealing ring 206. The frame 5 does not completely cover the upper open end of the cooling tank 2, but reserves enough space for the elastic particles to enter the cooling tank 2. The top of the frame 5 is fixedly connected to the lifting drive 6, and the output end of the lifting drive 6 is fixedly connected to the rotation drive 7. The output end of the rotation drive 7 is fixedly connected to the stirring rod 9 through the upper cover 8. The rotation drive 7 drives the stirring rod 9 to rotate through the upper cover 8 to stir the elastic particles in the cooling tank 2, thereby accelerating the cooling of the elastic particles. In fact, the lifting drive 6 usually adopts a cylinder, and the rotation drive 7 has only the shell fixedly connected to the movable end of the lifting drive 6, and the upper cover 8 is fixedly connected to the output shaft of the rotation drive 7. In this way, the upper cover 8 can not only rotate, but also lift. The opening and closing of the upper end of the cooling tank 2 is achieved by changing the height of the upper cover 8.

[0031] Working principle: When in use, it is detected whether the lower cover 4 is in the closed state, and the lifting drive 6 drives the upper cover 8 to rise, so that the upper open end of the cooling tank 2 leaks out, and the mixed elastic particles that need to be cooled are poured into the cooling tank 2, and then the upper cover 8 drops until the upper open end of the cooling tank 2 is completely covered. The heat-absorbing medium in the cooling tube 220 flows to absorb the heat transferred from the heat-conducting tube 204, and at the same time the rotary drive 7 is started, and the stirring rod 9 is driven to rotate by the upper cover 8, which can force the mixed elastic particles to roll in the cooling tank 2, and the particles in the center part are exchanged with the particles in the edge part, which speeds up the cooling speed, and the stability of the particles in the center and the edge parts is closer. When the stability of the elastic particles is reduced to an appropriate range, the hydraulic cylinder 3 can be started, and the lower cover 4 can be opened by contraction. The elastic particles are discharged from the cooling tank 2 under the action of their own gravity. After being discharged, the lower cover 4 can be closed again to carry out the next round of loading and cooling work.

[0032] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought.
