[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel and steel plates. In order to quickly cool down the steel structure during the production and processing, it is generally done by cold water spraying. The cooling device has a simple structure and is easy to maintain.

The utility model provides a cooling device for steel structure production and processing, which conveys the steel structure to the middle part of the inner cavity of the refrigeration box, then conveys the water in the water tank from the conveying water pipe 3 to the spraying device, then conveys the water to the nozzle through the spraying device, and then sprays the water onto the steel structure through the nozzle, thereby realizing the rapid cooling of the steel structure, and then effectively speeding up the cooling time of the steel structure through the arrangement of the collecting tank, the conveying water pipe 1, the circulating water pump, the conveying water pipe 2, the water tank, the conveying water pipe 3, the spraying device and the nozzle.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 , the utility model provides a technical solution:

[0024] Embodiment 1:

[0025] A cooling device for steel structure production and processing, comprising a cooling box 1, a mesh belt conveyor 4 and a frame 5. The inner cavity of the cooling box 1 is divided into a conveying cavity 101, a first cooling cavity 102 and a second cooling cavity 103 by a first partition 2 and a second partition 3. The mesh belt conveyor 4 is arranged in the conveying cavity 101 through the frame 5. A cooling mechanism 6 for the steel structure is arranged on one side of the upper part of the conveying cavity 101. The first partition 2 is V-shaped, and two reflux ports 8 are arranged at the lower end of the first partition 2. The two reflux ports 8 are connected and fixed to the water inlet end of a cooling coil 9 arranged inside the first cooling cavity 102. The water outlet end of the cooling coil 9 passes through the second partition 3 and is connected to the second cooling cavity 103. There is a height difference between the water inlet end and the water outlet end of the cooling coil 9. The water inlet end is higher than the water outlet end, so that the entire cooling coil 9 has a certain inclination, thereby ensuring that the coolant in the cooling coil 9 smoothly flows back to the second cooling cavity 103. Coolant is arranged in the first cooling cavity 102 and the second cooling cavity 103.

[0026] By arranging the first partition 2, the first cooling chamber 102 and the cooling coil 9 at the bottom of the mesh belt conveyor 4, the coolant sprayed on the steel structure can be recycled and reused. In the process of recycling to the second cooling chamber 103, the warm coolant flows along the first partition 2 to the reflux port 8 at the lower part, and then flows into the second cooling chamber 103 through the cooling coil 9 for circulating cooling treatment. When flowing through the cooling coil 9, the warm coolant in the cooling coil 9 is dissipated by the cold zone liquid in the first cooling chamber 102, thereby shortening the time for the coolant to be cooled again and improving the cooling efficiency.

[0027] The cooling mechanism 6 includes a servo pump 601, a liquid extraction pipe 602, a connecting pipe 603, a liquid outlet pipe 604 and a nozzle 605. The water inlet end of the servo pump 601 is connected to the interior of the second cooling chamber 103 through the liquid extraction pipe 602, and the water outlet end of the servo pump 601 is connected to the liquid outlet pipe 604 arranged on the upper part of the mesh belt conveyor 4 through the connecting pipe 603. A plurality of nozzles 605 are arranged at the bottom of the liquid outlet pipe 604. By setting up the cooling mechanism 6, the coolant in the second cooling chamber 103 is pumped into the liquid outlet pipe 604, and sprayed and cooled onto the steel structure placed on the mesh belt conveyor 4 through the nozzle 605.

[0028] A collecting chamber 7 is provided between the bottom of the mesh belt conveyor 4 and the first partition plate 2 for collecting and circulating cooling of the coolant.

[0029] An internal thread is provided on the inner side of the top end of the reflux port 8, and the internal thread is connected to the outer thread of the bottom end of the filter screen 10. The filter screen 10 is conical. By arranging the filter screen 10 on the upper part of the reflux port 8, impurities can be filtered. The conical filter screen 10 can effectively improve the blockage of the filter screen 10 and improve the filtering effect.

[0030] Collecting grooves 11 are provided on both sides of the reflux port 8. The collecting grooves 11 are used for collecting and precipitating impurities, and one end of the collecting groove 11 is fixedly connected to a discharge pipe 12 provided on the cooling box 1. A sealing cover 13 is threadedly connected to the outer side of the discharge pipe 12. By providing the collecting groove 11 at the lowest end of the V-shaped first partition 2, impurities are filtered during the circulation of the coolant, so that the impurities are precipitated in the collecting groove 11 at the lower end. When cleaning, the sealing cover 13 is opened and the impurities precipitated in the collecting groove 11 are removed through the discharge pipe 12 using a pipeline cleaning device.

[0031] A steam outlet pipe 14 is provided on the cooling box 1 above the nozzle 605 for discharging steam during the cooling process of the steel structure.

[0032] A hair dryer 16 is provided on the upper portion of the cooling box 1 on one side of the nozzle 605. The hair dryer 16 is used to dry residual water stains on the surface of the steel structure. By arranging the hair dryer 16 on the rear side of the cooling mechanism 6, the hair dryer can be used to blow away the residual water stains on the surface of the steel structure cooled by spraying on the mesh belt conveyor 4, thereby achieving a drying process and improving the cooling effect of the steel structure.

[0033] Working principle: When in use, the steel structure workpiece to be cooled is placed at one end of the mesh belt conveyor 4. At the same time, the coolant in the second cooling chamber 103 is driven by the servo pump 601 to pass into the nozzle 605. The steel structure workpiece transported on the mesh belt conveyor 4 is sprayed and cooled by the nozzle 605. The spray water finally falls into the collection chamber 7 and falls onto the first partition 2. The coolant flows to a lower place through the V-shaped first partition 2, and flows back to the second cooling chamber 103 through the reflux port 8 and the cooling coil 9 in the first cooling chamber 102 for circulation cooling. The cooling coil 9 in the cooling device realizes heat dissipation treatment of the coolant after spraying, thereby shortening the time for the coolant to cool down again and improving the cooling efficiency. The impurities in the coolant are filtered through the filter screen 10 on the reflux port 8. At this time, the impurities in the coolant will precipitate and accumulate in the collecting tank 11 at the lower part of the first partition 2. The sealing cover 13 is opened and the impurities precipitated in the collecting tank 11 are removed through the discharge pipe 12 by the pipeline cleaning device. The steel structure is cooled by the cooling mechanism 6 and then air-dried by the hair dryer 16. The dried steel structure is discharged through the other end of the mesh belt conveyor 4.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
