Description

Technical Field

[0001] This utility model relates to the field of cooling devices, specifically a cooling device for processing carbon steel water tank pipes. Background Technology

[0002] Carbon steel water collection tanks are pipes or box-type components made of carbon steel (an iron-carbon alloy with a carbon content of 0.02% to 2.11%), used for collecting, storing, or distributing water. Their structure typically combines the flow function of a pipe with the water collection / buffering function of a water tank. They are widely used in industrial circulating water systems, water supply / drainage projects, HVAC systems, and other applications, serving to stabilize water flow, balance pressure, or provide temporary water storage. During the processing of carbon steel water collection tanks (such as welding, forging, cutting, and heat treatment), a large amount of heat is generated due to the process. The amount of heat causes the material temperature to rise sharply. The core purpose of cooling is to control the material properties and avoid defects. At high temperatures, the internal grains of carbon steel will grow (coarsen) due to heat, and may even undergo phase transformation (such as austenitization). If the cooling rate is not controlled after processing, grain coarsening will lead to a decrease in material strength and hardness, and a decrease in toughness (easy to break). Rapid cooling (such as quenching) or slow cooling (such as annealing) can control the phase transformation process to obtain a fine grain structure or equilibrium structure, ensuring that the material meets the design requirements for strength, toughness and other properties. When carbon steel water collection pipes are cooled statically in a water tank, the cooling medium (water) cannot flow actively, resulting in low heat transfer efficiency and uneven temperature distribution. In a static water tank, the natural convection speed of the water is extremely slow. The water near the surface of the water collection pipe will heat up due to heat absorption (even locally boiling), forming a "high-temperature water layer"; while the water further away from the workpiece is at a lower temperature, forming a "low-temperature water layer". This temperature difference will lead to: large differences in heat dissipation rate in different parts: the heat dissipation rate of the upper part (in contact with the air-water interface), the lower part (in contact with the bottom of the water tank), and the side wall (completely immersed in water) of the water collection pipe are completely different; for pipe sections with thicker walls, flange connections, or structures with corners / grooves, static water is difficult to flow into the gaps. Heat cannot be dissipated in time in these areas and will remain at a high temperature for a long time, forming a huge temperature difference with the thin-walled areas, resulting in uneven thermal expansion and contraction, and a sharp concentration of internal stress, eventually causing bending, warping (deformation), or local cracking (especially at the transition between thick and thin walls). Utility Model Content

[0003] The purpose of this utility model is to provide a cooling device for processing carbon steel water collection tank pipes, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a cooling device for processing carbon steel water tank pipes is provided, comprising a cooling device body, a workpiece cooling frame installed inside the cooling device body, a side plate fixedly installed on the workpiece cooling frame, a cooling pool provided on the cooling device body, a receiving seat installed on the lower side inside the cooling pool, a workpiece cooling frame installed inside the receiving seat, a limiting seat fixedly installed on the side wall of the receiving seat, a limiting hole opened inside the limiting seat, a limiting post inserted inside the limiting hole, and the end of the limiting post fixedly connected to the inner wall of the cooling pool.

[0005] Furthermore, multiple sets of openings are equidistantly provided on the side plate, and the bottom of the workpiece cooling frame is engaged in the receiving groove provided inside the receiving seat. Both sides of the surface of the receiving seat are fixedly connected to the lifting frame.

[0006] Furthermore, the cooling device body also includes a stirring plate, a column, a reinforcing frame, a drive seat, a connecting rod, a turntable, and a drive motor, and two sets of limiting seats are connected to both sides of the receiving seat.

[0007] Furthermore, four sets of stirring blades are equidistantly arranged on the surface of the limiting seat. The stirring blades are in an "S" shape and are arranged on the outside of the workpiece cooling frame.

[0008] Furthermore, two sets of columns are fixedly installed on the end surface of the receiving seat, two sets of reinforcing frames are fixedly installed in the middle of the two sets of columns, and a drive seat is fixedly installed on the top of the two sets of columns.

[0009] Furthermore, a connecting rod is movably mounted on the front of the drive seat via a pin, and a turntable is movably mounted on the end of the connecting rod away from the drive seat via a pin. The rotating shaft of the turntable is fixed to the output shaft of the drive motor. The drive motor is mounted on the side wall of the cooling pool via a base. The workpiece cooling frame and the receiving seat are driven to reciprocate laterally via the turntable, the drive motor, the drive seat, and the connecting rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution uses a drive base to drive the workpiece cooling frame to move laterally inside the cooling tank via a column and a receiving seat. The cooling tank is filled with coolant, which can quickly cool the workpiece equipment inside the workpiece cooling frame. During the cooling process, the workpiece equipment is always in motion, and the water in the cooling tank is also in motion, which makes the water temperature in the cooling tank uniform and avoids large temperature differences. This prevents the workpiece equipment from bending, warping, or local cracking due to temperature differences during cooling. 2. This solution utilizes "S"-shaped agitators that, as they move with the workpiece cooling frame, can more efficiently cut and propel the coolant, creating more complex water vortices. This enhances the convection and mixing effects of the coolant. Combined with the lateral movement of the workpiece cooling frame, it further breaks the local static state of the water in the cooling pool, resulting in better water temperature uniformity. Simultaneously, it accelerates the heat exchange between the workpiece surface and the coolant, improving cooling speed and uniformity, and reducing quality problems caused by local temperature differences in the workpiece.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 This utility model provides a cooling device for processing carbon steel water tank pipes, including a cooling device body 200, a workpiece cooling frame 100 installed inside the cooling device body 200, a side plate 1 fixedly installed on the workpiece cooling frame 100, a cooling pool 20 provided on the cooling device body 200, a receiving seat 21 installed on the lower side inside the cooling pool 20, the workpiece cooling frame 100 installed inside the receiving seat 21, a limiting seat 22 fixedly installed on the side wall of the receiving seat 21, a limiting hole opened inside the limiting hole, a limiting post 24 inserted inside the limiting hole, and the end of the limiting post 24 fixedly connected to the inner wall of the cooling pool 20.

[0015] As a preferred embodiment, multiple sets of openings are equidistantly provided on the side plate 1, and the bottom of the workpiece cooling frame 100 is engaged in the receiving groove provided inside the receiving seat 21. Both sides of the surface of the receiving seat 21 are fixedly connected to the lifting frame 11.

[0016] The cooling device body 200 also includes an agitator 23, a column 25, a reinforcing frame 26, a drive seat 27, a connecting rod 28, a turntable 29, and a drive motor 290. Two sets of limiting seats 22 are connected to both sides of the receiving seat 21.

[0017] Four sets of stirring blades 23 are equidistantly arranged on the surface of the limiting seat 22. The stirring blades 23 are in an "S" shape and are arranged on the outside of the workpiece cooling frame 100.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown: The four sets of stirring blades 23 equidistantly arranged on the surface of the limiting seat 22 can make the stirring range more uniform and cover more areas in the cooling pool 20. When the "S"-shaped stirring blades 23 move with the workpiece cooling frame 100, they can cut and push the coolant more efficiently, forming a more complex water vortex, enhancing the convection and mixing effect of the coolant. Combined with the lateral movement of the workpiece cooling frame 100, it can further break the local static state of the water in the cooling pool 20, making the water temperature more uniform. At the same time, it accelerates the heat exchange between the workpiece equipment surface and the coolant, improves the cooling speed and cooling uniformity, and reduces the quality problems of the workpiece caused by local temperature differences.

[0019] In a preferred embodiment, two sets of columns 25 are fixedly provided on the end surface of the receiving seat 21, two sets of reinforcing frames 26 are fixedly installed in the middle of the two sets of columns 25, and a drive seat 27 is fixedly provided on the top of the two sets of columns 25.

[0020] A connecting rod 28 is movably mounted on the front of the drive base 27 via a pin. A turntable 29 is movably mounted on the end of the connecting rod 28 away from the drive base 27 via a pin. The rotating shaft of the turntable 29 is fixed to the output shaft of the drive motor 290. The drive motor 290 is mounted on the side wall of the cooling pool 20 via a base. The workpiece cooling frame 100 and the receiving seat 21 are driven to reciprocate laterally via the turntable 29, the drive motor 290, the drive base 27, and the connecting rod 28.

[0021] like Figure 4As shown: After the workpiece is placed inside the workpiece cooling frame 100, the drive motor 290 drives the turntable 29, connecting rod 28, drive seat 27, column 25 and receiving seat 21 to move the workpiece cooling frame 100 laterally in the cooling pool 20, so that the workpiece is always in motion and can contact the coolant in the cooling pool 20 more evenly, avoiding local cooling speed differences; at the same time, the water in the cooling pool 20 is also in motion due to the movement of the workpiece cooling frame 100, ensuring that the water temperature in the pool is always uniform, which can effectively avoid uneven cooling of the workpiece or quality defects caused by excessive temperature difference, and can also improve the overall cooling efficiency by continuous relative motion, so as to achieve rapid and high-quality cooling of the workpiece.

[0022] Working principle: The workpiece to be cooled is placed inside the workpiece cooling frame 100. At this time, the external switch of the drive motor 290 is turned on, and the output shaft of the drive motor 290 drives the turntable 29 to rotate. The turntable 29 drives the drive seat 27 to move laterally through the connecting rod 28. The drive seat 27 drives the workpiece cooling frame 100 to move laterally inside the cooling pool 20 through the column 25 and the receiving seat 21. The cooling pool 20 is filled with coolant, which can quickly cool the workpiece inside the workpiece cooling frame 100. During the cooling process, the workpiece is always in motion, and the water in the cooling pool 20 is also in motion, so that the water temperature in the cooling pool 20 is uniform, avoiding large temperature differences and preventing bending, warping or local cracking of the workpiece due to temperature differences during cooling.
