Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a sintering cooling treatment structure. Background Technology

[0002] Sintering is a process that transforms powdered materials or granules into a dense or strongly bound body through bonding between powder particles. The particles after sintering have high heat, which makes them difficult to collect and process during recycling.

[0003] Therefore, in order to cool the sintered particles and facilitate their collection, Chinese patent CN221649218U describes a cooling structure for sintered flux particles. The structure involves injecting the particles into a flow tank via an injection hopper, connecting a joint, and flowing through an inclined cylinder. A screw conveyor then drives the material to flow slowly. During this flow, a coolant pump is connected to inject coolant into the cooling flow tank. The coolant then flows between a second and a first flow plate, cooling the material inside the flow tank. While this patent can cool the sintered particles, it still presents certain technical problems. The patent simply uses a circulating plate to slow the flow, thereby increasing the efficiency of heat absorption by the medium, but it cannot quickly achieve heat dissipation. Therefore, over time, as the temperature of the medium increases, it affects the cooling of the sintered particles.

[0004] Therefore, based on the aforementioned prior art, in order to improve the heat dissipation efficiency of the cooling medium while reducing the flow rate of the cooling medium, a sintering cooling treatment structure is proposed, thereby solving the technical problems in the prior art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a sintering cooling structure that solves the problem that existing cooling devices cannot effectively dissipate heat from the cooling medium.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sintering cooling structure, comprising a base frame, a housing shell mounted on the upper surface of the base frame, a screw conveyor, a water tank, an air-cooling structure, and a drive structure. A multi-stage heat dissipation structure is installed inside the housing shell. The screw conveyor is installed within the multi-stage heat dissipation structure, and heat-absorbing plates are evenly distributed on the surface of the screw conveyor. The multi-stage heat dissipation structure includes an inner outer shell, a first inner shell, and a second inner shell. The inner outer shell is installed on the inner surface of the housing shell, the first inner shell is installed on the inner surface of the inner outer shell, and the second inner shell is installed on the inner surface of the first inner shell. The heat-absorbing plates are connected to the inner surface of the second inner shell. A cavity is formed between the outer surface of the inner outer shell and the inner surface of the housing shell. Multiple sets of connecting pipes are inserted through the surface of the inner outer shell, and a transverse connecting pipe connects adjacent sets of connecting pipes. The pipe is located between the inner shell and the first inner shell. The drive structure is installed on the upper surface of the outer shell and connected to the cavity and multi-stage heat dissipation structure through the connecting structure. The connecting structure includes a first connecting pipe, a second connecting pipe, a third connecting pipe, a fourth connecting pipe, and a fifth connecting pipe. The drive structure includes a first water pump and a second water pump. The water tank includes a water tank and a cooling medium tank. The water tank, the cooling medium tank, the first water pump, and the second water pump are all installed on the upper surface of the outer shell. The water inlet of the first water pump extends into the interior of the cooling medium tank, and the water outlet is connected to the fifth connecting pipe. The fifth connecting pipe passes through the outer shell, the inner shell, and the first inner shell and extends into the interior of the second inner shell. The surfaces of the second inner shell and the first inner shell are provided with openings. The opening on the surface of the first inner shell is connected to the second connecting pipe and passes through the outer shell and connects to the cooling medium tank.

[0007] Furthermore, through the above technical solution, the second water pump's inlet is connected to the water tank, the outlet is connected to the surface of the tank shell through a third connecting pipe, a fourth connecting pipe is connected to the lower end face of the tank shell, the port of the fourth connecting pipe is connected to the first connecting pipe, and the port of the first connecting pipe is connected to the water tank.

[0008] Furthermore, the second connecting pipe penetrates the water tank and extends through the water tank in a U-shape inside the water tank to the front end of the outer shell of the tank. The second connecting pipe located on the front end of the outer shell of the tank is located inside the air-cooling structure, and the first connecting pipe located on the front end of the outer shell of the tank also extends into the air-cooling structure.

[0009] As a preferred technical solution, the surfaces of two adjacent sets of heat-absorbing plates are provided with openings, and the opening positions are staggered, and the liquid inside the cooling medium tank flows from right to left.

[0010] Furthermore, the air-cooled structure includes a wind box and a fan. The wind box is installed on the front end face of the outer shell of the box, and the fan is installed on the front end face of the wind box. An opening is made on the outer surface of the wind box, and its first connecting pipe and second connecting pipe both penetrate the wind box and are arranged in a U-shape inside the wind box.

[0011] Compared with the prior art, the present invention provides a sintering cooling treatment structure, which has the following beneficial effects:

[0012] 1. This structure firstly cools the screw conveyor through the dual action of water and cooling medium. Water cools the cooling medium. When the sintered particles are poured into the feed hopper of the screw conveyor and begin to move to the right, the first and second water pumps start, filling the space between the outer and inner shells of the housing with water. The space between the inner shell and the first inner shell, and between the first and second inner shells, is filled with cooling medium. The water, through connecting pipes and transverse connecting pipes, increases the contact area with the cooling medium, thus providing a certain degree of cooling. Secondly, through the second connecting pipe, which passes through the water tank and is arranged in a U-shape within the tank, heat is absorbed again by the water, further reducing the cooling effect. The cooling medium's temperature is reduced, and the heat-absorbing plate increases the contact area with the cooling medium, allowing it to effectively absorb the temperature of the screw conveyor. Furthermore, the air-cooling structure further cools the cooling structure within the second connecting pipe. The openings on the heat-absorbing plate are arranged in alternating groups, thus effectively absorbing the screw conveyor's temperature while reducing the flow rate of the cooling medium. This significantly improves the cooling effect and prevents the cooling medium's temperature from rising due to continuous absorption of the screw conveyor's temperature, ensuring the cooling process of the sintered particles is not affected. Therefore, this solves the problem of existing cooling devices failing to effectively dissipate heat from the cooling medium. Attached Figure Description

[0026] 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.

[0027] Example

[0028] Please see Figure 1-12This utility model provides the following technical solution: a sintering cooling structure, including a base frame 1, a housing 2 mounted on the upper surface of the base frame 1, a screw conveyor 18, a water tank, an air-cooling structure, and a drive structure. The housing 2 contains a multi-stage heat dissipation structure. The screw conveyor 18 is installed within the multi-stage heat dissipation structure, and heat-absorbing plates 19 are evenly distributed on the surface of the screw conveyor 18. The multi-stage heat dissipation structure includes an inner housing 15, a first inner housing 16, and a second inner housing 17. The inner housing 15 is mounted on the inner surface of the housing 2. The first inner housing 16 is mounted on the inner surface of the inner housing 15, and the second inner housing 17 is mounted on the inner surface of the first inner housing 16. The heat-absorbing plates 19 are connected to the inner surface of the second inner housing 17. The outer surface of the inner housing 15 and the inner surface of the housing 2 form a cavity. Multiple sets of connecting pipes 20 are inserted through the surface of the inner housing 15. A transverse connecting pipe 14 is transversely connected between adjacent sets of connecting pipes 20. The transverse connecting pipe 14 is located within the inner... The drive structure is installed on the upper surface of the outer shell 2 between the outer shell 15 and the first inner shell 16, and is connected to the cavity and the multi-stage heat dissipation structure through the connecting structure. The connecting structure includes a first connecting pipe 9, a second connecting pipe 10, a third connecting pipe 11, a fourth connecting pipe 12, and a fifth connecting pipe 13. The drive structure includes a first water pump 7 and a second water pump 8. The water tank includes a water tank 5 and a cooling medium tank 6. The water tank 5, the cooling medium tank 6, the first water pump 7, and the second water pump 8 are all installed on the upper surface of the outer shell 2. The water inlet of the first water pump 7 extends into the interior of the cooling medium tank 6, and the water outlet is connected to the fifth connecting pipe 13. The fifth connecting pipe 13 passes through the outer shell 2, the inner shell 15, and the first inner shell 16 and extends into the interior of the second inner shell 17. The surfaces of the second inner shell 17 and the first inner shell 16 are provided with openings, wherein the opening on the surface of the first inner shell 16 is connected to the second connecting pipe 10 and passes through the outer shell 2 and connects to the cooling medium tank 6.

[0029] In this implementation plan, the specific working principle is as follows: In this structure, the user pours the sintered particles into a container such as... Figure 3 The feed is fed into the feed hopper of the screw conveyor 18 shown, and then begins to convey from left to right. At this time, the screw conveyor 18 is located in a multi-stage heat dissipation structure. Through the first water pump 7, the cooling medium in the cooling medium tank 6 is driven to enter the second inner shell 17 through the fifth connecting pipe 13, directly contacting the screw conveyor 18 and the heat absorption plate 19. Since the heat absorption plate 19 is installed on the surface of the screw conveyor 18, the contact area with the cooling medium is increased, which is conducive to the cooling medium absorbing heat. Then, through the action of the first water pump 7, the cooling medium enters the cavity between the first inner shell 16 and the second inner shell 17 through the opening on the surface of the second inner shell 17. See Figure 16 for details. Figure 5 and Figure 6As can be seen, the second water pump 8 drives the water in the water tank 5 to enter the cavity between the inner shell 15 and the outer shell 2 of the box through the third connecting pipe 11, and then enters the transverse connecting pipe 14 through the connecting pipe 20. Since the connecting pipe 20 and the transverse connecting pipe 14 are located between the inner shell 15 and the first inner shell 16, they can cool the cooling medium. At this time, the water returns to the water tank 5 through the fourth connecting pipe 12 and the first connecting pipe 9 via the air-cooling structure, while the cooling medium first enters the water tank 5 through the second connecting pipe 10 for preliminary cooling and then returns to the cooling medium tank 6 through the air-cooling structure, completing the cycle. Thus, the cooling medium achieves three cooling treatments, thereby effectively reducing the temperature of the cooling medium. Secondly, the opening on the surface of the heat absorption plate 19 slows down the flow rate of the cooling medium, which is more conducive to the cooling medium effectively absorbing the temperature of the screw conveyor 18, thereby significantly reducing the temperature of the sintered particles and achieving cooling treatment. Therefore, this structure can significantly reduce the temperature of the cooling medium while slowing down the flow rate of the cooling medium, solving the problem that existing cooling devices cannot effectively dissipate heat from the cooling medium.

[0030] According to the above description, for details on how the second water pump 8 drives the water circulation, please refer to [reference needed]. Figure 1-4 , Figure 7 , Figure 9 As can be seen, the water inlet of the second water pump 8 is connected to the water tank 5, and the water outlet is connected to the surface of the outer shell 2 of the housing through the third connecting pipe 11. The lower end face of the outer shell 2 of the housing is connected to the fourth connecting pipe 12, and the port of the fourth connecting pipe 12 is connected to the first connecting pipe 9. The port of the first connecting pipe 9 is connected to the water tank 5. The third connecting pipe 11 is connected to the outer shell 2 of the housing, so that the water fills the cavity between the outer shell 2 of the housing and the inner shell 15, thereby effectively cooling the cooling medium. Then, the water in the cavity is introduced into the air-cooled structure through the first connecting pipe 9 through the fourth connecting pipe 12 to achieve air-cooling treatment, and then returned to the water tank 5.

[0031] To further improve the pretreatment and cooling of the cooling medium inside the second connecting pipe 10, please refer to [the relevant documentation]. Figure 9 and Figure 10 As can be seen, the second connecting pipe 10 penetrates the water tank 5 and extends through the water tank 5 in a U-shape to the front end of the outer shell 2. This effectively increases the contact area between the pipe and the water in the water tank 5, thereby effectively reducing the temperature of the cooling medium in the second connecting pipe 10. The second connecting pipe 10 located at the front end of the outer shell 2 is located within the air-cooling structure, and the first connecting pipe 9 located at the front end of the outer shell 2 also extends into the air-cooling structure.

[0032] To improve the absorption of temperature by the cooling medium on the screw conveyor 18, please refer to the following for details. Figure 11 and Figure 12 As can be seen, the surfaces of the two adjacent sets of heat absorption plates 19 are provided with openings, and the opening positions are staggered. The liquid inside the cooling medium tank 6 flows from right to left, and the purpose of the flow is that the screw conveyor 18 is conveyed from left to right. Therefore, the temperature on the left side is high and the temperature on the right side is low. This allows the temperature to gradually decrease during conveying, which is beneficial to the heat dissipation of the screw conveyor 18 and thus effectively improves the cooling of the sintered particles inside the screw conveyor 18.

[0033] For further heat dissipation of water and cooling medium, please refer to [link / reference needed]. Figure 3 and Figure 4 As can be seen, the air-cooled structure includes a wind box 3 and a fan 4. The wind box 3 is installed on the front end face of the outer shell 2, and the fan 4 is installed on the front end face of the wind box 3. An opening is made on the outer surface of the wind box 3, and its first connecting pipe 9 and second connecting pipe 10 both pass through the wind box 3 and are arranged in a U-shape inside the wind box 3.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
