Description

Technical Field

[0001] The utility model relates to the technical field of seamless steel pipe processing, and particularly relates to a cooling device for seamless steel pipe processing. Background Technique

[0002] A seamless steel pipe is a tubular product without welded seams, usually made of a single metal or alloy material. It is formed through hot working and cold working processes to ensure its structural integrity and strength. During the manufacturing process of seamless steel pipes, a solid round steel is first pierced to form a hollow shell, and then further processed into steel pipes of the required size and shape through processes such as rolling and drawing. Seamless steel pipes are widely used in multiple industries due to their high strength, good pressure resistance, uniform wall thickness, and excellent corrosion resistance, including oil and gas transportation, chemical industry, automotive manufacturing, building structures, aerospace, and machinery manufacturing. These applications usually require the steel pipes to have a high degree of reliability and safety, so seamless steel pipes have become the preferred material in many critical applications.

[0003] The cooling device for seamless steel pipe production is a key equipment used to control and adjust the temperature of steel pipes during the manufacturing process of seamless steel pipes. During the heat treatment, forming, and processing of seamless steel pipes, the steel pipes need to undergo high-temperature heating and then be cooled to achieve the required mechanical properties and dimensional stability. The design and efficiency of the cooling device are crucial for the final quality of the steel pipes. The water spray cooling device is one of the most common cooling devices. It directly sprays cooling water onto the surface of the steel pipe through high-pressure nozzles to achieve rapid cooling. The nozzles can be arranged around the steel pipe to ensure uniform cooling. Some devices also rotate the steel pipe to enable omnidirectional spraying and ensure uniform cooling.

[0004] Although the water spray cooling device for seamless steel pipes in the prior art meets the usage requirements to a certain extent, it is found in the actual use process that a large amount of steam is generated when the water spray cooling device for seamless steel pipes cools the seamless steel pipes, which cannot be recycled and treated. While causing water resource waste, a large amount of water vapor will increase the humidity and temperature inside the workshop, affecting the workshop environment. Content of the Utility Model

[0024] The condensation mechanism 210 includes a housing 211. A semiconductor refrigeration sheet 212 is fixedly installed on one side of the housing 211. A plurality of heat pipes 213 are fixedly installed on one side of the semiconductor refrigeration sheet 212. A plurality of corrugated plates 214 are fixedly installed on the outer wall of the heat pipe 213;

[0025] One side of the semiconductor refrigeration sheet 212 is fixedly connected to a heat dissipation fin 216, and a heat dissipation fan 217 is fixedly installed on one side of the heat dissipation fin 216;

[0026] A reflux groove 215 is fixedly installed at the bottom of the housing 211. Observation windows 205 are provided on one side of the steam recovery hood 201 and the air-cooling hood 204.

[0027] The specific implementation method is as follows: The steam recovery hood 201 provided at the top of the spray ring 104 prevents the escape of water vapor during the cooling process. Then, the blower 203 is used to extract the water vapor and send it into the interior of the condensation mechanism 210 for condensation and dehumidification. The air after condensation and dehumidification is sprayed into the interior of the air-cooling hood 204 through the blower 203 to blow the steel pipe after spray cooling, and the moisture remaining on the surface of the steel pipe is dried;

[0028] Furthermore, when water vapor passes through the inside of the housing 211, the heat pipe 213 is cooled by the thermoelectric cooler 212, and then the temperature of several corrugated plates 214 is reduced through the heat pipe 213. When the water vapor passes by the corrugated plates 214, it will condense on the surface of the corrugated plates 214 and then fall into the inside of the return groove 215, and finally return to the inside of the water tank 101, solving the problem of resource waste caused by the inability to recover water vapor. The heat generating surface of the thermoelectric cooler 212 is dissipated by the cooperation between the heat dissipation fins 216 and the cooling fan 217 to ensure the stable operation of the thermoelectric cooler 212.

[0029] Please refer to Figures 1-4 , the present utility model provides a technical solution: a cooling device for seamless steel pipe processing. The cooling mechanism 1 includes a water tank 101. A cooling table 102 is fixedly installed on the top of the water tank 101. Several guide rollers 107 are rotatably installed on the top of the cooling table 102. An arc surface 108 is provided on the outer wall of the guide roller 107. Several spray rings 104 are fixedly installed on the top of the cooling table 102.

[0031] A circulation pump 106 is fixedly installed inside the water tank 101. A compression refrigeration machine 111 is fixedly installed on one side of the water tank 101.

[0032] The specific implementation mode is as follows: The coolant is stored in the water tank 101, and the coolant is cooled by the compression refrigeration machine 111 to ensure the cooling effect. The steel pipe is driven to run stably at a constant speed on the top of the cooling table 102 through the cooperation of the motor 109 and the synchronous transmission component 110. Then, through the cooperation between the spray ring 104 and the spray heads 105, the outer wall of the steel pipe is evenly sprayed. The displacement speed of the steel pipe is stable, and the spraying has no dead angle, ensuring uniform cooling and guaranteeing the dimensional accuracy and mechanical properties of the steel pipe after cooling. The coolant sprayed by the spray heads 105 flows back into the inside of the water tank 101 through the recovery groove 103, and then the coolant circulates through the cooperation between the circulation pump 106 and the recovery groove 103.

[0033] Working principle: When using the cooling device for seamless steel pipe processing, the coolant is stored in the water tank 101, and the coolant is cooled by the compression refrigerator 111 to ensure the cooling effect. The steel pipe is driven to run stably at a constant speed on the top of the cooling table 102 through the cooperation of the motor 109 and the synchronous transmission assembly 110. Then, through the cooperation between the spray ring 104 and the spray head 105, the outer wall of the steel pipe is evenly sprayed. The displacement speed of the steel pipe is stable, and the spraying has no dead angle, ensuring uniform cooling and guaranteeing the dimensional accuracy and mechanical properties of the steel pipe after cooling. The coolant sprayed by the spray head 105 flows back into the interior of the water tank 101 through the recovery tank 103, and then the coolant circulates through the cooperation between the circulation pump 106 and the recovery tank 103;

[0034] During this process, the steam recovery cover 201 arranged on the top of the spray ring 104 prevents the water vapor from escaping during the cooling process. Then, the blower 203 sucks away the water vapor and sends it into the interior of the condensation mechanism 210 for condensation and dehumidification. The air after condensation and dehumidification is sprayed into the interior of the air-cooling cover 204 by the blower 203 to blow the steel pipe after spray cooling and dry the residual moisture on the surface of the steel pipe;

[0035] Furthermore: When the water vapor passes through the interior of the housing 211, the thermoelectric cooler 212 cools the heat pipe 213, and then the heat pipe 213 reduces the temperature of several corrugated plates 214. The water vapor will condense on the surface of the corrugated plates 214 when passing by the corrugated plates 214 and then fall into the interior of the return tank 215, and finally flow back into the interior of the water tank 101, solving the problem of resource waste caused by the inability to recover water vapor. The heat dissipation fin 216 and the heat dissipation fan 217 cooperate to dissipate heat from the heating surface of the thermoelectric cooler 212 to ensure the stable operation of the thermoelectric cooler 212.
