[0002] In the metallurgical industry, continuous annealing furnace is an important equipment used to improve the properties of metal materials. During the continuous annealing process, metal sheets pass through the furnace, through heating and cooling links, to achieve grain refinement, stress relief and optimization of material properties.

In addition, a blowing mechanism can disperse the water mist sprayed by the spray mechanism to improve the uniformity of the water mist spraying. However, after the cooling work is completed, some coolant often remains on the surface of the metal parts, and it is necessary to wait for the coolant to dry before the next processing step can be carried out. In order to ensure continuous production and improve production efficiency, the metal parts need to be manually transferred to external drying equipment for drying, which increases the workload of the staff and reduces work efficiency. Moreover, the transportation of large quantities of metal parts also requires the help of external transportation tools, which increases the cost of use.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 2 The utility model provides an embodiment of a cooling device for a continuous annealing furnace, comprising an annealing furnace body 1, a base 2 being fixedly connected to the right side of the annealing furnace body 1, and a supporting leg being provided at the bottom of the base 2 to improve the stability of the equipment, a cooling box 3 being fixedly connected to the top of the base 2, and a conveying device being provided on the top of the base 2 for moving the metal parts to be cooled to the right, and the conveying device can use an electric roller, which is a prior art, and a spray mechanism is provided inside the cooling box 3, the spray mechanism comprising a water storage tank 4 and a spray head 6, a liquid pump being provided in the water storage tank 4 for providing power to spray the coolant from the spray head 6, a liquid replenishing tank 5 for replenishing the coolant into the water storage tank 4 being fixedly connected to the top of the water storage tank 4, the spray head 6 being connected to the water storage tank 4 through a connecting pipe, and the spray head 6 being fixedly connected to the top of the inner wall of the cooling box 3 and arranged in a matrix to ensure that the coolant can evenly cover the surface of the metal parts to be cooled.

[0032] Reference Figure 1 - Figure 3 The cooling box 3 is provided with a blowing mechanism inside, and the blowing mechanism includes a bellows 7. A high-speed fan 9 is fixedly connected to the inside of the bellows 7. The airflow generated can cool the metal parts to be cooled. It is a prior art. A slot 11 is provided inside the bellows 7. A hollow reinforcement plate 10 is inserted into the inner wall of the slot 11, and a positioning mechanism is provided on the top of the reinforcement plate 10.

[0033] Reference Figure 3 、 Figure 4 The positioning mechanism includes a protrusion 12, which is set in an inclined state. The protrusion 12 is fixedly mounted on the top of the reinforcement plate 10. A groove 13 is provided inside the bellows 7 to match the protrusion 12. The protrusion 12 is inserted into the groove 13. The number of protrusions 12 is set to two groups. The two groups of protrusions 12 are arranged in an eight-shaped shape on the top of the reinforcement plate 10. In the process of inserting the reinforcement plate 10 into the slot 11, the displacement direction of the protrusion 12 is guided by the groove 13, thereby ensuring the rationality of the installation position of the reinforcement plate 10 and leaving a suitable installation space for the subsequent filter plate 15.

[0034] Reference Figure 3 、 Figure 4The reinforcement plate 10 is fixedly connected to the bellows 7 by fastening bolts 14, and a filter plate 15 is inserted into the inner wall of the slot 11. An elastic spring piece 22 is installed on the bottom inner wall of the reinforcement plate 10. The spring piece 22 is naturally arc-shaped when not subject to external force and protrudes in the direction close to the filter plate 15. The bottom of the spring piece 22 contacts the top of the filter plate 15. When the reinforcement plate 10 is installed, the filter plate 15 is inserted into the slot 11, which squeezes the spring piece 22, causing the spring piece 22 to deform under force and completely enter the interior of the reinforcement plate 10. At the same time, the spring piece 22 will exert a reaction force on the filter plate 15 to increase the stability of the installation of the filter plate 15. A limiting mechanism is provided inside the filter plate 15.

[0035] Reference Figure 2 - Figure 4 The limiting mechanism includes a control rod 17, which is slidably mounted on the inner wall of the filter plate 15. The sliding direction of the control rod 17 is left and right. The limiting mechanism also includes a rope 18. The rope 18 is not elastic so as to achieve a stable transmission effect. One end of the rope 18 is fixedly connected to the surface of the control rod 17. One end of the rope 18 is fixedly connected to a limiting rod 19. The limiting rod 19 is slidably mounted on the inner wall of the filter plate 15. The control rod 17 moves to the right, pulling the two sets of limiting rods 19 closer to each other through the rope 18. The number of limit rods 19 is set to two groups. The sides of the two groups of limit rods 19 that are close to each other are elastically connected to the inner wall of the filter plate 15 through a spring 20. By setting the spring 20, the two groups of limit rods 19 have a tendency to move away from each other. A limit groove 21 that cooperates with the limit rod 19 is provided on the inner wall of the slot 11. A handle 16 is fixedly connected to the right side of the filter plate 15 for the convenience of the staff to pull the filter plate 15, which is convenient and labor-saving. A through groove 8 is provided on the surface of the base 2 to facilitate the passage of airflow and increase the air flow rate.

[0036] Working principle: When in use, the metal parts processed by the annealing furnace body 1 move to the right and enter the cooling box 3, and the water pump inside the water tank 4 works, so that the coolant in the water tank 4 is sprayed out from the spray head 6 through the connecting pipe and sprayed on the surface of the metal parts to be cooled, thereby taking away the heat for cooling. Then the metal parts continue to move to the right, and when passing the bottom of the high-speed fan 9, the high-speed fan 9 generates airflow, thereby transferring the heat of the metal parts to the air for further cooling. At the same time, the coolant remaining on the surface of the metal parts can be quickly dried, which facilitates the rapid transfer of the metal parts to the next processing step, and can achieve continuous processing, thereby improving production efficiency.

[0037] When the filter plate 15 needs to be replaced and cleaned after working for a long time, by pulling the control rod 17 to the right, the control rod 17 is moved through the transmission action of the rope 18, so that the two sets of limit rods 19 overcome the elastic force of the spring 20 and move away from each other, thereby making the limit rods 19 completely disengaged from the inside of the limit groove 21, and then pulling the handle 16 to the right, the filter plate 15 can be easily and quickly taken out from the inside of the bellows 7. The filter plate 15 can be disassembled and replaced without removing the reinforcement plate 10, thereby improving work efficiency.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
