Description

An air-cooling device for processing liquefied petroleum gas hoses Technical Field

[0001] This utility model relates to the field of liquefied petroleum gas hose processing technology, specifically to an air-cooling device for processing liquefied petroleum gas hoses. Background Technology

[0002] During the production and processing of liquefied petroleum gas hoses, a large amount of heat is generated after the hoses undergo processes such as extrusion and vulcanization. Timely cooling is necessary to ensure the dimensional stability and excellent performance of the hoses.

[0003] In existing equipment, after the liquefied petroleum gas hose is processed, it is sent into the air-cooling box by a conveying mechanism. The cold air generated by the fan is guided along the air duct to the area around the hose, where it exchanges heat with the hose surface and removes the heat generated during the processing, thereby cooling the hose.

[0004] However, the existing technology mostly uses a single fan direct blowing mode to cool the liquefied petroleum gas hose, which has low cooling efficiency and affects the processing efficiency of liquefied petroleum gas hose.

[0005] Therefore, we urgently need to provide an air-cooling device for processing liquefied petroleum gas hoses. Summary of the Invention

[0006] The purpose of this invention is to provide an air-cooling device for processing liquefied petroleum gas hoses, so as to solve the problem of low cooling efficiency mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air-cooling device for processing liquefied petroleum gas hoses, comprising an air-cooling box, a conveyor belt, and a box door. The conveyor belt is installed inside the air-cooling box, and the box door is installed on the left and right sides of the front of the air-cooling box. An air-cooling device is provided inside the air-cooling box, and the air-cooling device includes a cooling mechanism, a pre-cooling mechanism, and a circulation mechanism.

[0008] The cooling mechanism is located inside the air-cooled box on the right side, the pre-cooling mechanism is located inside the air-cooled box on the left side, and the circulation mechanism is located on the back of the air-cooled box.

[0009] The cooling mechanism includes a blower, a main pipe, a branch pipe, an air outlet pipe, a housing, a cold water tank, a pump body, an inlet pipe, a cooling pipe, and an outlet pipe. The blower is installed on the back of the air-cooled housing. The main pipe is connected to the output end of the blower. The branch pipe is connected to the end of the main pipe away from the blower. The air outlet pipe is connected to the front of the branch pipe and located on the right side of the inner wall of the air-cooled housing. The housing is fixedly installed on the inner wall of the air-cooled housing. The cold water tank is installed at the upper right corner of the top of the air-cooled housing. The pump body is installed on the back of the cold water tank. One end of the inlet pipe is connected to the output end of the pump body.

[0010] Preferably, the front of the housing has an air outlet, and the air outlet pipe is connected to the back of the housing, so that the air blown by the blower can be blown into the housing through the air outlet pipe and blown onto the surface of the liquefied petroleum gas hose on the conveyor belt through the air outlet, thereby cooling the liquefied petroleum gas hose.

[0011] Preferably, the cooling pipe is bent and coiled inside the shell to increase the flow distance of the cold water inside the cooling pipe, thereby cooling the air blown out of the air outlet pipe and allowing the cooled air to be blown onto the surface of the liquefied petroleum gas hose, thus accelerating the cooling of the liquefied petroleum gas hose and improving the cooling efficiency.

[0012] Preferably, the precooling mechanism includes a second branch pipe, a second air outlet pipe, and a partition. The second branch pipe is connected to the end of the main pipe away from the blower. The second air outlet pipe is connected to the front of the second branch pipe and extends into the interior of the air-cooled box.

[0013] Preferably, the circulation mechanism includes a cooling box, a thermoelectric cooler, a second pump body, and a return pipe. The cooling box is installed on the lower right side of the back of the air-cooled box, the thermoelectric cooler is installed inside the cooling box, the second pump body is installed on the right side of the cold water tank, and the first air outlet pipe is connected to the output end of the second pump body.

[0014] Preferably, the lower end of the outlet pipe is connected to the top of the cooling tank, and the end of the return pipe away from the second pump body is connected to the right side of the cooling tank, so that the cold water in the cooling pipe flows into the cooling tank through the outlet pipe. At the same time, under the action of the second pump body, the cold water in the cooling tank is pumped back into the cold water tank, realizing the recycling of cold water and saving resources.

[0015] Preferably, the thermoelectric cooler is connected to a power source via a wire, with the cooling end of the thermoelectric cooler located inside the cooling chamber and the heat dissipation end located outside the cooling chamber. The heat dissipation end is equipped with heat dissipation fins. The thermoelectric cooler cools the water in the cooling chamber, enabling subsequent water recycling.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This air-cooling device for processing liquefied petroleum gas hoses, by setting up a cooling mechanism, draws cold water from the cold water tank through a pump body and allows it to enter the cooling pipe along the inlet pipe. As the cold water flows through the cooling pipe, it cools the air blown out of the outlet pipe. The cooled air is then blown onto the surface of the liquefied petroleum gas hose, thereby accelerating the cooling of the liquefied petroleum gas hose and improving the cooling efficiency.

[0018] 2. The air-cooling device for processing liquefied petroleum gas hoses, by setting a pre-cooling mechanism, can reduce the surface temperature of the liquefied petroleum gas hoses more evenly through pre-cooling, avoiding defects such as deformation and cracks in the hoses caused by rapid temperature changes or local overheating.

Pump body 2 603 is installed on the right side of cold water tank 406. Air outlet pipe 1 404 is connected to the output end of pump body 2 603. The lower end of water outlet pipe 410 is connected to the top of cooling box 601. The end of return pipe 604 away from pump body 2 603 is connected to the right side of cooling box 601, so that the cold water in cooling pipe 409 flows into cooling box 601 through water outlet pipe 410. At the same time, under the action of pump body 2 603, the cold water in cooling box 601 is pumped back into cold water tank 406, realizing the recycling of cold water and saving resources.

[0032] In use, the liquefied petroleum gas (LPG) hose to be cooled is placed on top of conveyor belt 2. The LPG hose is conveyed from left to right by conveyor belt 2. Simultaneously, blower 401 and pump body 407 are started. When the LPG hose moves to the left side of partition 503, the air blown by blower 401 is blown through branch pipe 501 and outlet pipe 502 onto the surface of the LPG hose, pre-cooling it. When the LPG hose moves to the right side of partition 503, blower 401... The blown air is blown into the housing 405 through the outlet pipe 404 via the branch pipe 403. In conjunction with the pump body 407, the cold water in the cold water tank 406 is drawn out and flows into the cooling pipe 409 along the water inlet pipe 408. As the cold water flows in the cooling pipe 409, it cools the air blown out of the outlet pipe 404. The cooled air is then blown onto the surface of the liquefied petroleum gas hose, thereby accelerating the cooling of the liquefied petroleum gas hose and improving the cooling efficiency, thus completing the cooling operation of the liquefied petroleum gas hose.
