Description

Technical Field

[0001] The utility model relates to a device capable of collecting and discharging condensed water generated on the inner wall of a vertical air duct. Background Art

[0002] At present, when feed mills produce pellets, the material at the exit of the pellet mill is about 90℃. In order to cool the pellets to room temperature ±5℃, a cooler is needed to cool the pellets. Figure 1 As shown, the air outside the cooler enters the cooler from the air inlet at the bottom of the cooler under the action of the cooling fan, penetrates the material layer in the cooler and is discharged from the air outlet at the top of the cooler. The air will take away a large amount of heat from the material when passing through the material layer, thereby increasing the air temperature to form hot air with a higher temperature. The hot air enters the vertical air duct after passing through the discharger from the horizontal air duct, and is then discharged through the vertical air duct. However, after entering the vertical air duct, the hot air contacts the inner wall of the vertical air duct with a lower temperature, which will produce a certain amount of condensed water. The produced condensed water will flow downward along the inner wall of the vertical air duct to the inside of the discharger.

[0003] In addition, when the air passes through the material layer, it will take away some of the powder in the material, and the powder will be brought into the discharger under the action of hot air. In this way, when the condensed water flows into the discharger, it will mix with the powder. The mixture of condensed water and powder will cause the material on the inner wall of the discharger to stick to the wall, which will not only increase the material residue in the discharger, but also easily block the discharger. In addition, the powder in the discharger will enter the subsequent production process through the air lock. The mixture of condensed water and powder will increase the moisture content of the powder, and then increase the moisture content of the final product, affecting the quality of the final product.

[0026] Embodiment

[0027] Please refer to Figures 2 to 7 As shown, a device 1 provided by the present utility model that can collect and discharge the condensed water generated on the inner wall of the vertical air duct includes a housing 11, an inner housing 12, an upper flange 13 and a lower flange 14. The bottom of the upper flange 13 is fixedly connected to the top of the housing 11, and the top of the lower flange 14 is fixedly connected to the bottom of the inner housing 12. The inner housing 12 is coaxially sleeved inside the housing 11 and is located in the middle and lower part. An annular gap is formed between the inner housing 12 and the housing 11. A water collecting bottom plate 15 is provided at the bottom of the annular gap. An annular water collecting area 16 is formed among the inner housing 11, the housing 12 and the water collecting bottom plate 15. A condensed water drain port 17 is provided at the bottom on one side of the water collecting area 16.

[0028] In this embodiment, please further combine with Figure 6 and Figure 7 As shown, the water collecting bottom plate 15 is inclined in a way that one end close to the condensed water drain port 17 is lower and one end far from the condensed water drain port 17 is higher. In this way, a certain slope is formed at the bottom of the water collecting area 16, so that the condensed water can naturally gather along the slope to the condensed water drain port 17 after entering the water collecting area 16, which is beneficial to discharging the condensed water outside the device 1 from the condensed water drain port 17, ensuring that all the condensed water in the device 1 is discharged, and enabling the device 1 to operate for a long time without water accumulation. Since the water collecting area 16 is formed by connecting the inner housing 11, the housing 12 and the water collecting bottom plate 15, the inclination angle of the water collecting bottom plate 15 is equal to the slope at the bottom of the water collecting area 16. In this embodiment, the inclination angle θ of the water collecting bottom plate 15 is 2-5°, preferably 3°.

[0029] In this embodiment, please further combine with Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, cleaning ports are respectively provided on the left and right sides of the housing 11, and a cleanable cleaning cover 18 is provided on the cleaning port (the position corresponding to the cleaning cover 18 is the position of the cleaning port), which is beneficial to cleaning the water collecting area 16 inside the device 1 and keeping the inside of the device 1 clean.

[0030] In addition, a quick-opening handle 19 is provided on one side of the cleaning port. The quick-opening handle 19 is fixedly provided on the housing 11. The opening and closing end of the cleaning cover 18 is detachably connected to the quick-opening handle 19, and the cleaning cover 18 can be quickly opened or closed through the quick-opening handle 19. The cleaning cover 18 and the quick-opening handle 19 can be set by using existing technologies.

[0031] In this embodiment, please further combine with Figure 3 andFigure 4 As shown, the part of the outer housing 11 above the water collection bottom plate 15 is integrally a hollow frustum shape with a smaller upper part and a larger lower part, and the part of the outer housing 11 below the water collection bottom plate 15 is integrally an inverted hollow frustum shape with a larger upper part and a smaller lower part. The frustum shape design of the upper part of the outer housing 11 is more conducive to the condensed water flowing down along the inner wall of the outer housing 11 into the water collection area 16. The inverted frustum shape of the lower part of the outer housing 11 can leave a clearance space for the condensed water drain port 17, facilitating the external connection of a drain pipe at the condensed water drain port 17.

[0032] In addition, the upper part of the inner housing 12 is integrally a hollow frustum shape with a smaller upper part and a larger lower part, and the lower part of the inner housing 12 is integrally a cylindrical shape with an equal diameter. The upper end of the lower part of the inner housing 12 passes through the water collection bottom plate 15 and extends upward, thereby forming an annular water collection area 16 between the inner housing 12 and the outer housing 11; the lower part of the outer housing 11 is fixedly connected to the outer lower part of the inner housing 12, which can strengthen the connection firmness between the outer housing 11 and the inner housing 12, and at the same time make the overall appearance of the device 1 more beautiful.

[0033] The working method of the device provided by the present utility model that can collect and discharge the condensed water generated on the inner wall of the vertical air duct is as follows:

[0034] As Figure 8 shown, the device 1 is installed between the vertical air duct 2 and the unloader 3. Specifically: the upper flange 13 at the top of the device 1 is connected to the bottom of the vertical air duct 2 through fasteners (for example, bolts), and the lower flange 14 at the bottom of the device 1 is connected to the unloader 3 through fasteners (for example, bolts). And, an auxiliary air duct 4 is vertically connected between the lower flange 14 and the unloader 3 (so that there is a certain space between the bottom of the device 1 and the top of the unloader 3, facilitating the external connection of a drain pipe to the condensed water drain port 17). In this way, the device 1 is installed between the vertical air duct 2 and the unloader 3. During the entire installation process, only conventional fasteners are required to cooperate with the upper flange 13 and the lower flange 14 to achieve the installation of the device 1. The installation is convenient and also facilitates the subsequent replacement and maintenance of the vertical air duct 2 and the unloader 3;

[0035] During use, the air outside the cooler 5 enters the cooler 5 from the air inlet at the bottom of the cooler 5 under the action of the cooling fan 6, penetrates the material layer inside the cooler 5, and then is discharged from the air outlet at the top of the cooler 5. When the air passes through the material layer, it will carry away a large amount of heat of the material, thereby increasing the air temperature and forming hot air with a higher temperature. The hot air enters the auxiliary air duct 4 after passing through the horizontal air duct 7 and the unloader 3, and is discharged from the vertical air duct 2 after passing through the auxiliary air duct 4 and the device 1. After the hot air enters the vertical air duct 2, it contacts the inner wall of the vertical air duct 2 with a lower temperature and generates a certain amount of condensed water. The generated condensed water will flow downward along the inner wall of the vertical air duct 2. The downward-flowing condensed water enters the outer housing 11 through the upper flange 13, flows downward along the inner wall of the outer housing 11 to the water collection area 16, and is discharged outside the device 1 from the condensed water drain port 17 at the bottom of the water collection area 16 (the condensed water drain port 17 can be externally connected to a drain pipe, and the condensed water is drained away through the drain pipe). In this way, the collection and discharge of the condensed water generated on the inner wall of the vertical air duct 2 can be realized through the device 1.

[0036] As described above, after the device 1 of the present invention is installed between the vertical air duct 2 and the unloader 3, the device 1 can collect and discharge the condensed water generated on the inner wall of the vertical air duct 2. The condensed water generated on the inner wall of the vertical air duct 2 will not flow into the unloader 3 as Figure 1 shown, but will be directly discharged outside the system through the condensed water drain port 17 of the device 1 as Figure 8 shown. Since the condensed water will not flow into the unloader 3, the powder in the unloader 3 will not be mixed with the condensed water. Therefore, the problems of material sticking to the inner wall and blockage of the unloader 3 can be effectively avoided, and the moisture content of the powder in the unloader 3 will not increase either. As a result, when the powder in the unloader 3 enters the subsequent production process through the air lock 8, it will not cause an increase in the moisture content of the final product, thus effectively ensuring the quality of the final product.

[0037] Finally, it is necessary to point out here that the above description is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
