Description

Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to a cooling box for spraying water on a kiln body. Background Art

[0002] During the production process of some industrial furnaces, in order to protect the refractory materials inside the furnace, it is necessary to cool the kiln body. The medium used for cooling is water. To reduce water resource consumption, this part of water is recycled water. During normal production, there is a problem of high water temperature, which is not conducive to the protection of refractory materials.

[0003] For example, the spray treatment system for a rotary kiln disclosed in the patent publication number CN219368335U sprays liquid onto the surface of the rotary kiln furnace body through a spray head. The liquid flows downward into the water collecting tank, and then the liquid is transported to the water inlet tank again through a recovery water pump to achieve the recycling of the liquid. Another example is a cooling device for a rotary kiln furnace disclosed in the patent publication number CN217764388U, which sprays water upward onto the surface of the rotary kiln furnace body through a water spray pipe to cool it. The water on the surface of the rotary kiln furnace body will drip into the retainer for recycling.

[0004] It can be seen from this that the water sprayed on the surface of the rotary kiln furnace is affected by high temperature and its temperature will rise, that is, the temperature of the liquid will increase during the recycling process. If it is not cooled and still recycled, then the water sprayed on the furnace surface is hot water with a certain temperature, obviously this cannot achieve the purpose of cooling, and the cooling effect is poor. Summary of the Invention

[0005] In order to solve the problem that the temperature of the recycled water used for kiln cooling rises after repeated use, resulting in poor cooling effect, the utility model provides a cooling box for spraying water on a kiln body. A cooling box is arranged below the kiln furnace. The water sprayed on the surface of the kiln furnace falls onto the cooling box, and the cooling box can effectively dissipate heat and cool the water, avoiding the situation that the temperature of the recycled water rises after repeated use.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0007] A cooling box for spraying water on a kiln body is arranged below the kiln furnace body to facilitate the cooling of the recycled water sprayed on the kiln furnace body. It includes a cooling box body filled with recycled water, a water receiving tray, a cooling chamber, a fan and a flow buffering component. The water receiving tray is arranged at the top of the cooling box body. The water receiving tray is a stepped structure formed by multiple bends, which is convenient for increasing the contact area between the recycled water and the external air. Both ends of the water receiving tray are hollowed out to communicate with the cooling box body, facilitating the recycled water to flow into the interior of the cooling box body;

[0008] A cooling chamber is arranged in the middle of the cooling box body. Fans are arranged on both side walls of the cooling box body corresponding to the cooling chamber, facilitating blowing air into the cooling chamber. The bottom surface of the cooling chamber is hollowed out to facilitate air outlet. There is a certain distance between the bottom surface of the cooling chamber and the circulating water level, which does not affect normal air outlet.

[0009] Slow-flow components are symmetrically arranged on both sides of the cooling box body, which increases the flow path of the circulating water. The liquid on the water receiving tray flows downward onto the slow-flow components. The slow-flow components include a plurality of slow-flow plates for the flow of circulating water arranged in a vertically staggered manner. The end of each slow-flow plate is hollowed out along the flowing direction of the circulating water to facilitate the dispersion of the circulating water. Convection channels are formed between the plurality of slow-flow plates.

[0010] Heat dissipation holes are formed on the side wall of the cooling box body. The air in the cooling chamber flows along the convection channel and flows out of the cooling box body through the heat dissipation holes. The air and the circulating water form convection, which can cool down again.

[0011] Further, the cooling box body is of a rectangular structure. The water receiving tray closes the top opening of the cooling box body. The left and right sides of the water receiving tray are symmetrical. Each side of the water receiving tray is of a multi-level stepped shape, with the middle part of the water receiving tray being high and the two ends being low, facilitating the flow of the circulating water towards the two ends of the water receiving tray.

[0012] The two ends of the water receiving tray are bent downward to form return water pipes. The return water pipes are semi-circular structures made of mesh plates. The liquid on the water receiving tray flows downward through the return water pipes onto the slow-flow components.

[0013] Further, the two side walls of the cooling box body extend vertically upward and protrude from the return water pipes to form water blocking side plates to prevent the circulating water from overflowing from the return water pipes. Water blocking stepped plates are arranged at the tops of the other two side walls of the cooling box body. The water blocking stepped plates and the water blocking side plates are connected and combined to form a "mouth" shape surrounding the water receiving tray on all four sides to prevent the circulating water from flowing out of the water receiving tray.

[0014] Further, a plurality of heat dissipation fins are arranged on the water receiving tray. The plurality of heat dissipation fins are arranged at intervals along the axial direction of the return water pipes, increasing the contact area with the circulating water to facilitate better heat dissipation. Each heat dissipation fin is bent multiple times along the edge contour of the water receiving tray. The length of the heat dissipation fin is less than the length of the water receiving tray, and the end of the heat dissipation fin does not cover the return water pipe to avoid blocking the return water pipe.

[0015] Further, a partition plate bent in a "U" shape is arranged in the middle of the cooling box body. The partition plate, the middle part of the water receiving tray and the two side walls of the cooling box body enclose a rectangular cooling chamber; the bottom surface of the partition plate is in a mesh shape, and the liquid level of the circulating water contained in the cooling box body is lower than the bottom surface of the partition plate. The bottom surface of the partition plate is flush with the lowermost slow-flow plate.

[0016] Further, a plurality of the flow retardation plates are distributed parallel to each other vertically, and a flow interception plate is arranged at the end of each flow retardation plate. The flow interception plate is a "﹂"-shaped plate body made of a mesh plate; there is a gap between two adjacent flow retardation plates vertically, and the convection channel is bent in an "S" shape, increasing the convection flow path of the circulating water and air.

[0017] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0018] The structure of the present utility model is reasonably designed. There is a stepped water receiving tray at the top of the cooling box body, increasing the natural heat dissipation area of the circulating water. During the process of the circulating water flowing on the water receiving tray, it comes into large-area contact with the air, thereby achieving natural cooling. The preliminarily cooled circulating water enters the flow retardation assembly through the dispersion of the return water pipe for secondary cooling, and the return water pipe also has a certain filtering function.

[0019] The flow retardation assembly of the present utility model is composed of a plurality of flow retardation plates arranged vertically and offset from each other. An "S"-shaped convection channel is formed between the plurality of flow retardation plates. The outside air is blown into the cooling chamber by a fan. After flowing out from the bottom of the cooling chamber, the air flows upward in the convection channel. At the same time, the circulating water also flows downward in the convection channel. Furthermore, the circulating water and the air form convection, further removing the heat of the circulating water, and finally discharging the heat through the heat dissipation holes, realizing the secondary cooling of the circulating water, thereby achieving an effective cooling effect.

Detailed implementation mode

[0026] The following combines the attached drawings to make a detailed description of the specific implementation mode of the present utility model:

[0027] As Figures 1 to 5 shown, a cooling box for spraying water on the kiln body is arranged below the kiln furnace body 1, and is sent to the upper part of the kiln furnace body 1 by a circulating water pump and then sprayed on the surface of the kiln furnace body 1. The circulating water can cool it, and the cooled circulating water falls into the cooling box below the kiln furnace body 1, and the cooling box realizes the cooling of the circulating water so as to be recycled again, as Figure 1 shown.

[0028] The cooling box for spraying water on the kiln body includes a cooling box body 2 filled with circulating water, a water receiving tray 3, a cooling chamber 4, a fan 5 and a flow buffering component, as Figure 2 shown. The cooling box body 2 is a rectangular structure with an open upper end. A water receiving tray 3 is arranged at the top of the cooling box body 2. The water receiving tray 3 can close the opening at the top of the cooling box body 2. The water receiving tray 3 can be understood as the lid of the cooling box body 2. A hollow closed cooling box is formed by combining the cooling box body 2 and the water receiving tray 3.

[0029] The circulating water falling from the surface of the kiln furnace body 1 first falls on the water receiving tray 3, and is naturally cooled by the water receiving tray 3. The water receiving tray 3 is a stepped structure formed by multiple bends. The left and right sides of the water receiving tray 3 are symmetrical, and each side of the water receiving tray 3 is a multi-level stepped shape. Therefore, the middle of the water receiving tray 3 is high and the two ends are low. During the process of the circulating water flowing on the multi-level of the water receiving tray 3, the natural heat dissipation area of the circulating water is increased, and then the circulating water and the outside air are in large-area contact for natural cooling.

[0030] Both ends of the water receiving tray 3 are hollowed out to communicate with the cooling box body 2. Specifically, both ends of the water receiving tray 3 are bent downward to form a return water pipe 6. The return water pipe 6 is a semi-circular structure made of a mesh plate, and the return water pipe 6 also has a filtering function, as Figure 3 shown. The circulating water flows on the water receiving tray 3 and finally flows into the return water pipe 6, and then enters the cooling box body 2 downward.

[0031] Since there is no shelter around the water receiving tray 3, in order to prevent the circulating water from flowing out of the water receiving tray 3, the two side walls of the cooling box body 2 extend vertically upward and protrude from the return water pipe 6 to form water blocking side plates 7. When the circulating water converges into the return water pipe 6, the water blocking side plates 7 can block it to prevent the circulating water from overflowing from the return water pipe 6.

[0032] At the same time, water blocking stepped plates 8 are arranged at the tops of the other two side walls of the cooling box body 2. The water blocking stepped plates 8 are bent multiple times and are consistent with the water receiving tray 3, and the water blocking stepped plates 8 can block both ends of the return water pipe 6. After the water blocking stepped plates 8 and the water blocking side plates 7 are connected and combined, they form a "mouth" shape surrounding the four sides of the water receiving tray 3, so as to prevent the circulating water from overflowing from the water receiving tray 3.

[0033] The circulating water passing through the water receiving tray 3 enters the interior of the cooling box body 2. In order to achieve further cooling of the circulating water, a cooling chamber 4 is arranged in the middle of the cooling box body 2. Specifically, a partition plate 41 bent in a "U" shape is arranged in the middle of the cooling box body 2. The top of the partition plate 41 is closed by the middle part of the water receiving tray 3, and both sides of the partition plate 41 are closed by the side walls of the cooling box body 2. Thus, a rectangular cooling chamber 4 is formed after the partition plate 41, the middle part of the water receiving tray 3 and the two side walls of the cooling box body 2 are enclosed.

[0034] Fans 5 are arranged on both side walls of the cooling box body 2 corresponding to the cooling chamber 4, facilitating blowing air into the cooling chamber 4. The bottom surface of the cooling chamber 4 is hollowed out, that is, the bottom surface of the partition plate 41 is in a mesh shape; there is a certain distance between the bottom surface of the cooling chamber 4 and the liquid level of the circulating water, that is, the liquid level of the circulating water contained in the cooling box body 2 is lower than the bottom surface of the partition plate 41, and the circulating water will not submerge the bottom surface of the cooling chamber 4.

[0035] Buffering components are symmetrically arranged on both sides of the cooling box body 2. The liquid on the water receiving tray 3 flows downward onto the buffering components, that is, the liquid on the water receiving tray 3 flows downward through the return pipe 6 onto the buffering components. The buffering components can extend the flow path of the circulating water in the cooling box body 2, as Figure 4 shown.

[0036] The buffering components include four buffering plates 9 for the flow of circulating water arranged in a vertically staggered manner. The four buffering plates 9 are distributed parallel to each other up and down, and the bottom surface of the partition plate 41 is flush with the lowermost buffering plate 9. Along the flow direction of the circulating water, the end of each buffering plate 9 is hollowed out. Specifically, a cut-off plate 91 is arranged at the end of each buffering plate 9. The cut-off plate 91 is a "﹂"-shaped plate body made of a mesh plate. The cut-off plate 91 can disperse the circulating water and make it flow downward onto the next layer of buffering plate 9.

[0037] When installing the buffering plates 9, the three-week sides of two of the buffering plates 9 are connected and fixed to three adjacent side walls of the cooling box body 2, and the three-week sides of the remaining two buffering plates 9 are connected to the corresponding two side walls of the cooling box body 2 and the side wall of the partition plate 41. The cut-off plates 91 at the ends of the buffering plates 9 are arranged in a suspended manner.

[0038] There is a gap between two adjacent buffering plates 9 up and down. A convection channel 10 is formed between the four buffering plates 9. The convection channel 10 is bent in an "S" shape. Heat dissipation holes 12 are opened on the side wall of the cooling box body 2. The heat dissipation holes 12 are located above the buffering components. The air in the cooling chamber 4 flows along the convection channel 10 and flows out of the cooling box body 2 through the heat dissipation holes 12.

[0039] The principle of this utility model is as follows: The circulating water that is poured on the surface of the kiln furnace body 1 falls downward onto the water receiving tray 3. The circulating water can flow to both sides of the water receiving tray 3. During the flowing process, it comes into contact with air over a large area for cooling, and then flows into the return water pipe 6. The return water pipe 6 disperses the circulating water and then flows it onto the flow slowing assembly. After the fan 5 is started, it blows air into the cooling chamber 4. The air in the cooling chamber 4 flows downward and gradually rises along the convection channel 10, passes through four flow slowing plates 9 in sequence from bottom to top, and finally the air is discharged from the heat dissipation holes 12.

[0040] During the process of the above air flowing along the convection channel 10, the circulating water flows downward in sequence on the flow slowing plate 9. When the circulating water passes through the intercepting plate 91, it is dispersed and comes into contact with air over a larger area. In this way, the circulating water and air meet in the convection channel 10 to form convection, which can further take away the heat in the circulating water, thereby achieving the cooling effect of the circulating water and enabling it to be used for spraying on the surface of the kiln furnace body 1 again.

[0041] In order to optimize the product structure and increase the heat dissipation effect of the circulating water on the water receiving tray 3, a number of heat dissipation fins 11 are provided on the water receiving tray 3. The number of heat dissipation fins 11 are arranged at intervals along the axial direction of the return water pipe 6. Each heat dissipation fin 11 is bent multiple times along the edge contour of the water receiving tray 3. Through the heat dissipation fins 11, it is possible to better promote the cooling of the circulating water, as Figure 5 shown. The length of the heat dissipation fin 11 is less than the length of the water receiving tray 3, and the end of the heat dissipation fin 11 does not cover the return water pipe 6. The purpose is not to block the return water pipe 6 and to facilitate the cleaning of the return water pipe 6 without affecting the normal operation of the return water pipe 6.

[0042] The above-described embodiments are only the preferred embodiments of this utility model and do not limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made according to the structure, features, and principles described in the scope of this utility model patent should be included within the scope of this utility model's patent application.
