Description

Technical Field

[0001] This utility model belongs to the field of chemical solid material cooling technology, and in particular relates to a chemical solid material cooling device based on inert gas blowing. Background Technology

[0002] In a narrow sense, materials refer to raw materials or raw materials, while in a broad sense, materials include all items related to product production, such as raw materials, auxiliary supplies, semi-finished products, and finished products.

[0003] Some solid materials, especially chemical solid materials, are produced at high temperatures, making packaging and subsequent processing difficult. They are easily damaged by heat, causing unnecessary quality problems. Therefore, cooling treatment is necessary. However, existing cooling methods can easily cause the materials to become damp, and some gases in the air may react with the materials, affecting their quality. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling device for chemical solid materials based on inert gas blowing, which solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a chemical solid material cooling device based on inert gas injection, comprising a nitrogen cylinder, a chiller, a silo, and a gas cooling mechanism. The top of the silo is connected to an inlet and an exhaust pipe, and the rear end of the silo is connected to an outlet pipe. The gas cooling mechanism includes an air pump, a connecting pipe, and a fixing ring. The top of the air pump has an intake pipe, and the side of the air pump has a delivery pipe. The connecting pipe is located at the top of the chiller. The fixing ring is fixedly connected inside the silo, and the inner side of the fixing ring is connected to a spray pipe with spray holes on its surface. A stirring mechanism is located at the middle end of the connecting pipe.

[0006] Furthermore, the end of the gas delivery pipe away from the gas pump is connected to the refrigerator through and fixedly connected. When the gas pump is turned on, nitrogen gas is drawn from the nitrogen cylinder through the suction pipe and delivered to the refrigerator through the gas delivery pipe.

[0007] Furthermore, the end of the connecting pipe away from the refrigerator is connected to the fixed ring through and fixedly connected. After the refrigerator cools the nitrogen, it is delivered to the fixed ring through the connecting pipe.

[0008] Furthermore, the number of nozzles is set to ten sets, and the ten sets of nozzles are arranged in an equidistant circular array inside the fixed ring, through which cooling nitrogen is delivered to the silo.

[0009] Furthermore, the agitation mechanism includes a bin body, which is fixedly connected to the bottom of the silo. A rotating shaft is rotatably connected inside the bin body, and an agitator rod and a fan blade are fixedly connected to the surface of the rotating shaft.

[0010] Furthermore, the silo body is connected to the connecting pipe, and the rotating shaft is rotatably connected to the bottom of the silo, allowing nitrogen gas inside the connecting pipe to pass through the silo body.

[0011] Furthermore, one side of the fan blade is set as a straight surface, and the other side of the fan blade is set as an arc surface. The number of fan blades is set to three sets. When nitrogen flows, it will contact the arc surface of the fan blade, thereby driving the shaft to rotate.

[0012] This utility model has the following beneficial effects: This invention incorporates a gas cooling mechanism, which, through the cooperation of components such as an air pump, suction pipe, and delivery pipe, delivers cooled nitrogen gas into a fixed ring. Finally, the cooled nitrogen gas is ejected from the nozzle on the spray pipe, carrying away the heat from the material in the silo. At the same time, the nitrogen gas is dry, has a very low moisture content, is an inert gas, does not easily react with the material, and is fluid, thus achieving rapid cooling.

[0013] This invention incorporates a stirring mechanism, which, during the process of a gas pump driving nitrogen through a connecting pipe to a fixed ring, allows the nitrogen to pass through the silo. As the nitrogen flows, it contacts the arc surface of the fan blades, causing the rotating shaft to rotate. The rotating shaft then drives the stirring rod to agitate the material in the silo, accelerating the cooling efficiency. Simultaneously, it ensures that the nitrogen does not have excessive pressure when entering the silo, allowing the nitrogen to remain in the silo for a longer period.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] Please see Figures 1-5 As shown, this utility model is a chemical solid material cooling device based on inert gas blowing, including a nitrogen cylinder 1, a refrigerator 2, a silo 3, and a gas cooling mechanism 7. The top of the silo 3 is connected to an inlet 4 and an exhaust pipe 6, and the rear end of the silo 3 is connected to an outlet pipe 5. The gas cooling mechanism 7 includes an air pump 71, a connecting pipe 74, and a fixing ring 75. The top of the air pump 71 is provided with an air suction pipe 72, and the side of the air pump 71 is provided with an air delivery pipe 73. The connecting pipe 74 is located on the top of the refrigerator 2. The fixing ring 75 is fixedly connected to the inside of the silo 3. The inner side of the fixing ring 75 is connected to a spray pipe 76, and the surface of the spray pipe 76 is provided with spray holes 77. The middle end of the connecting pipe 74 is provided with a stirring mechanism 8.

[0020] As shown in the figure, the end of the gas supply pipe 73 away from the gas pump 71 is connected to the refrigerator 2 through and fixedly connected. When the gas pump 71 is turned on, nitrogen gas in the nitrogen cylinder 1 is drawn in through the suction pipe 72 and delivered to the refrigerator 2 through the gas supply pipe 73.

[0021] As shown in the figure, the end of the connecting pipe 74 away from the refrigerator 2 passes through and is fixedly connected to the fixed ring 75. After the refrigerator 2 cools the nitrogen, it is transported to the fixed ring 75 through the connecting pipe 74.

[0022] As shown in the figure, the number of nozzles 76 is set to ten sets, and the ten sets of nozzles 76 are arranged in an equidistant circular array inside the fixed ring 75. Cooling nitrogen is delivered to the silo 3 through the ten sets of nozzles 76 and the nozzle holes 77 on them.

[0023] As shown in the figure, the stirring mechanism 8 includes a bin body 81, which is fixedly connected to the bottom of the bin 3. A rotating shaft 82 is rotatably connected inside the bin body 81, and a stirring rod 83 and a fan blade 84 are fixedly connected to the surface of the rotating shaft 82.

[0024] As shown in the figure, the silo body 81 is connected to the connecting pipe 74, and the rotating shaft 82 is connected to the bottom of the silo 3 through and rotates. Nitrogen gas in the connecting pipe 74 will pass through the silo body 81.

[0025] As shown in the figure, one side of the fan blade 84 is set as a straight surface, and the other side of the fan blade 84 is set as an arc surface. The number of fan blades 84 is set to three sets. When the nitrogen flows, it will contact the arc surface of the fan blade 84, thereby driving the rotating shaft 82 to rotate.

[0026] A specific application of this embodiment is as follows: Solid chemical materials are fed into the silo 3 through the inlet 4. The inlet 4 and outlet pipe 5 are closed, and the air pump 71 is turned on. At this time, nitrogen gas is drawn from the nitrogen cylinder 1 through the suction pipe 72 and transported to the chiller 2 through the gas delivery pipe 73. The chiller 2 cools the nitrogen gas. The cooled nitrogen gas is then transported to the fixing ring 75 through the connecting pipe 74. Ten sets of nozzles 76 and their nozzles 77 deliver the cooled nitrogen gas to the silo 3. The cooled nitrogen gas removes heat from the material in the silo 3, and simultaneously dries the moisture content. The nitrogen gas is very low in temperature and is an inert gas. It is inexpensive, does not easily react with materials, and is fluid, thus cooling the material quickly. The waste gas is discharged through the waste gas pipe 6, while the nitrogen gas flows through the connecting pipe 74 and passes through the silo 81. When the nitrogen gas flows, it will contact the arc surface of the fan blade 84, thereby driving the rotating shaft 82 to rotate. The rotation of the rotating shaft 82 drives the stirring rod 83 to rotate, which agitates the material in the silo 3, allowing the nitrogen gas to have more sufficient contact with the material. At the same time, it also ensures that the nitrogen gas does not have too high a pressure when it enters the silo 3, so that the nitrogen gas stays in the silo 3 for a longer time.
