Description

Technical Field

[0002] In the field of shot blasting, alloy shot is an important shot blasting material, and its quality directly affects the shot blasting effect. Traditional heat treatment methods for alloy shot processing have many problems.

[0003] On the one hand, in the heating process, traditional heating methods are inefficient and difficult to control precisely, resulting in unstable heating of the alloy pellets and affecting subsequent processing steps. Moreover, the heating process often cannot be effectively integrated with subsequent quenching and sieving processes, reducing overall production efficiency.

[0004] On the other hand, existing equipment for quenching and sieving processes is ineffective in achieving satisfactory quenching results. The quenching fluid and alloy shot cannot fully contact each other, making it difficult to guarantee quenching quality. Furthermore, the sieving function is limited, failing to accurately separate alloy shot of different sizes and thus unable to meet diverse shot blasting needs. Moreover, the quenching fluid often lacks an effective recycling mechanism, leading to resource waste and increased production costs.

[0005] To address these issues, improve the efficiency and quality of alloy shot processing and heat treatment, reduce production costs, and simultaneously achieve the recycling of quenching fluid, this patent proposes a novel heat treatment device for alloy shot processing in shot blasting.

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.

[0028] This utility model provides, for example Figures 1-4The apparatus shown is a heat treatment device for processing alloy shot for shot blasting. It includes a guide hopper 1 with an inclined lower inner wall. Multiple heating tubes 2 are connected to the right side of the lower end of the guide hopper 1. A quenching and screening box 3 is fixedly connected to the lower end of the guide hopper 1 via an upper support rod, with the multiple heating tubes 2 located on the upper right side of the quenching and screening box 3.

Support legs 5 are fixedly connected to the four corners of the lower end of the return trough 4. The alloy shot to be blasted needs to be heat-treated after rolling. The process involves eliminating the internal stress of the alloy shot, enhancing its surface hardness, and improving its microstructure to produce qualified shot blasting. The alloy shot is placed inside the guide hopper 1 and rolls through the inclined inner wall at the lower end of the guide hopper 1 into multiple heating tubes 2, where it is rapidly heated. The heated alloy shot then falls into the quenching and screening box 3, where it is quenched and screened. The quenching liquid and alloy shots that are not up to size fall into the return tank 4 at the lower end of the quenching and screening box 3, and are finally discharged through the drain port at the lower end of the return tank 4.

[0029] Preferably, a heating coil 6 is provided on the outside of the heating tube 2. When the alloy pellet passes through the inside of the heating tube 2, it can be heated by electromagnetic induction through the heating coil 6. The heating temperature of the alloy pellet can be controlled by controlling the magnitude of the current inside the heating coil 6, which can improve heating efficiency and accurately control the heating temperature.

[0030] Preferably, the quenching sieve box 3 has multiple inclined sieve plates 7 fixedly connected inside, and a gap is provided between the lowest point of the inclination of the multiple sieve plates 7 and the inner wall of the quenching sieve box 3.

Each of the multiple sieve plates 7 has multiple sieve holes 8 inside, and the inner diameter of the multiple sieve holes 8 inside the multiple sieve plates 7 increases from top to bottom. Inclined collection plates 9 are fixedly connected to the lower end of the multiple sieve plates 7 near the gap with the inner wall of the quenching sieve box 3. The multiple collection plates 9 are arranged vertically and alternately, and the inclination directions of two adjacent collection plates 9 are opposite, and they are located between the multiple sieve plates 7. Each of the multiple collection plates 9 has an outlet window 10 at the lowest point of its inclination. Windows 10 are respectively opened inside the outer walls of the left and right ends of the guide hopper 1. Each of the multiple outlet windows 10 is provided with a collection guide groove 11 with its lower inner wall inclined. The multiple collection guide grooves 11 are respectively fixedly connected to the outer walls of the left and right ends of the guide hopper 1. After the alloy shot enters the quenching and screening box 3, it rolls from top to bottom through the upper end of multiple inclined screening plates 7 under the action of gravity. It is screened through multiple screening holes 8 of different diameters inside the multiple screening plates 7, thereby screening out alloy shot of different diameters. The screened alloy shot falls through the multiple screening holes 8 onto the upper end of the inclined collection plate 9 and rolls to the outlet window 10 under the action of gravity. Then it is guided into the collection guide groove 11 through the outlet window 10 and finally discharged and collected through the rear end of the collection guide groove 11.

A filter 16 is installed in the middle of the circulation pipe 14, and the filter 16 is located on the upper side of the return tank 4. When... When the alloy shot falls through multiple heating pipes 2 onto the uppermost sieve plate 7, the quenching nozzle 12 sprays quenching liquid into the quenching sieve box 3 through multiple quenching nozzles 13, and sprays it onto the uppermost sieve plate 7, thereby quenching the heated alloy shot. The alloy shot and quenching liquid can fully contact each other through the obstruction and dispersion of multiple sieve plates 7, improving quenching efficiency and quenching quality. At the same time, the quenching liquid can dissipate heat through the obstruction and dispersion of multiple sieve plates 7, allowing the quenching liquid flowing back into the return tank 4 to cool to room temperature.

[0032] Preferably, the quenching liquid flowing back into the return tank 4 can be drawn into the circulation pipe 14 by the circulation pump 15 and filtered in the filter 16 in the middle of the circulation pipe 14. The filtered quenching liquid is then introduced into the quenching nozzle 12 through the circulation pipe 14 for recycling, thereby reducing heat treatment costs.
