[0002] In many industrial sectors such as food processing and chemical production, rapid and uniform cooling of materials is a crucial step in ensuring product quality and improving production efficiency. Traditional cooling methods, such as natural cooling and air cooling, often suffer from slow cooling rates, uneven cooling, and high energy consumption, making it difficult to meet the demands of modern production for high efficiency, energy saving, and environmental protection.
[0003] With the continuous development of industrial technology, spray cooling technology has gradually received widespread attention. Spray cooling uses nozzles to spray a cooling medium (such as cooling water) in a mist form onto the surface of materials, utilizing the latent heat of vaporization and sensible heat of the cooling medium to absorb heat from the materials, thereby achieving rapid cooling. However, traditional spray cooling devices also have some problems, such as low efficiency of cooling water recycling, unstable cooling effect, and complex device structure.
[0004] To solve the above problems, a tunnel-type spray cooling device is needed. Utility Model Content
[0005] The purpose of this invention is to provide a tunnel-type spray cooling device that solves the problem that traditional cooling methods in the prior art are slow and cannot meet the needs of high-efficiency production.

Simultaneously, by precisely controlling the water flow of the circulating and cooling pumps, the device can flexibly adjust the temperatures of the pre-cooling and cooling sections to adapt to the cooling requirements of different materials.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] The specific connection methods for each component all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the existing field. The machinery, parts, and equipment all adopt conventional models in the existing technology. In addition, the circuit connections adopt conventional connection methods in the existing technology, which will not be described in detail here. The component models mentioned in this article are all common models in the existing technology and can be replaced according to actual needs.
[0027] As per the instruction manual Figure 1-3As shown, this utility model provides a tunnel-type spray cooling device, including a cooling tunnel body 1, a conveying system installed on the cooling tunnel body 1, and a cooling water circulation spraying system. The cooling tunnel body 1 is a metal frame with a closed channel structure, which can be welded from stainless steel and has multiple layers of heat-insulating lining inside to form a stable cooling working space. Support columns 12 and water pipes 11 are installed below the cooling tunnel body 1.
[0028] The cooling tunnel body 1 is equipped with a pre-cooling section and a cooling section. The temperature of the pre-cooling section is 50-60℃, and the temperature of the cooling section is 25-30℃. The pre-cooling section is located at the entrance side of the cooling tunnel body 1 and is used to perform preliminary cooling treatment on the high-temperature material to avoid surface stress damage caused by excessive temperature difference. The cooling section is located at the rear end of the pre-cooling section and is used to reduce the material temperature to the target range. By setting the temperature in this stage to be lower than that in the pre-cooling section, a stable decrease in the core temperature of the material can be ensured.
[0029] The conveying system includes main synchronous pulleys 8 and driven synchronous pulleys 2 located at both ends of the cooling tunnel body 1. The main synchronous pulleys 8 are connected to the motor component 6 via a belt. A synchronous belt 16 is installed between the main synchronous pulleys 8 and the driven synchronous pulleys 2, and several drainage holes 13 are distributed on the synchronous belt 16. The main synchronous pulleys 8 drive the synchronous belt 16 via a steel gear structure, and the distance between them is adjusted according to the length of the cooling tunnel body 1. The material is placed on the surface of the synchronous belt 16 with drainage holes 13 for conveying. During the spray cooling process, the cooling water sprayed on the surface of the material can be discharged downward through the drainage holes 13 on the surface of the synchronous belt 16.
[0030] The cooling water circulating spray system includes a water storage tank 18, a cooling pump 7, a circulating pump 4, and a spray assembly 9. The water storage tank 18 and the circulating pump 4 are connected via an extraction pipe 5, and the circulating pump 4 and the spray assembly 9 are connected via a delivery pipe 3. The cooling pump 7 is connected to the water storage tank 18, and the cooling pump 7 and the spray assembly 9 are connected via a cooling water pipe 10. The cooling pump 7 and the circulating pump 4 are located on both sides of the cooling tunnel body 1. The device is equipped with several cooling pumps 7 and circulating pumps 4. The water storage tank 18 is located below the synchronous belt 16. The cooling water pipe 10 and the delivery pipe 3 converge at the spray assembly 9. Both the cooling water pipe 10 and the delivery pipe 3 are equipped with one-way valves to prevent the cooling water and circulating water from flowing in opposite directions within the pipes.
[0031] After the material is conveyed into the cooling tunnel via the synchronous belt 16, the circulating pump 4 pumps the recovered water from the storage tank 18 through the conveying pipe 3 into the spray assembly 9 to form a basic cooling water curtain. Simultaneously, the cooling pump 7 injects externally supplied low-temperature cooling water into the spray assembly 9 through an independent pipe. The spray assembly 9 can be equipped with a three-way valve to achieve fluid convergence. The design of placing the two pumps on opposite sides of the tunnel creates a counter-current effect in the pipes, effectively improving the stability of the spray pressure. By precisely controlling the water delivery of the circulating pump 4 and the cooling pump 7, the device can flexibly adjust the temperature of the pre-cooling and cooling sections to adapt to the cooling requirements of different materials. The spray heads 15 cover the material surface in a staggered arrangement. After the cooling water comes into contact with the high-temperature material, it evaporates and absorbs heat. The residual water flows back to the storage tank 18 through the drainage holes 13 on the synchronous belt 16, and after sedimentation and filtration, it re-enters the circulation system.
[0032] The bottom of the water storage tank 18 is provided with a drain hole 17, which can drain the water after cooling, or add water to the water storage tank 18 by connecting the water supply pipe 11 at the beginning of device startup. During operation, the drain hole can be plugged.
[0033] The spray assembly 9 includes multiple rows of parallel, transversely arranged spray conveyor rods 14, which extend along the width of the synchronous belt 16. Spray heads 15, evenly distributed below them, form multiple rows of parallel atomizing areas. When the synchronous belt 16 carrying material passes beneath the spray assembly 9, cooling water is distributed to each spray head 15 via the spray conveyor rods 14, forming a uniform atomized water flow covering the material surface. The spray assembly 9 is located directly above the synchronous belt 16, allowing the atomized water flow to directly act on the material, avoiding uneven coverage caused by tilted spraying. Simultaneously, gravity accelerates the return of cooling water to the water storage tank 18.
[0034] Therefore, the tunnel-type spray cooling device with the above-mentioned structure of this utility model solves the problem that the traditional cooling method in the prior art is slow and difficult to meet the needs of high-efficiency production. It combines the advantages of tunnel-type conveying system and spray cooling system. Through a series of measures such as optimizing structural design, improving cooling water circulation efficiency and enhancing the stability of cooling effect, it achieves rapid, uniform and efficient cooling of materials.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
