Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a crossflow cooling tower for concentrated milk processing. Background Technology

[0002] A cooling tower is a device that uses a coolant to absorb heat from a system and release it into the atmosphere in order to lower the coolant temperature. Common cooling towers are divided into crossflow cooling towers and counterflow cooling towers. Crossflow cooling towers use air intakes on both sides, with the air flowing horizontally through the packing material to exchange heat with the liquid sprayed from top to bottom.

[0003] In the production of concentrated milk, milk needs to be sterilized at high temperature and then cooled before use. However, when using existing crossflow cooling devices, the milk cannot have sufficient contact with the air, and the air stays in the cooling tower for a short time and is discharged quickly, resulting in low milk cooling efficiency. Utility Model Content

[0004] The purpose of this application is to provide a crossflow cooling tower for concentrated milk processing, in order to solve the problem that in the use of existing crossflow cooling devices, milk cannot make sufficient contact with air, and the air has a short residence time in the cooling tower and a fast discharge rate, resulting in low milk cooling efficiency.

[0005] To solve the above-mentioned technical problems, this application provides a crossflow cooling tower for concentrated milk processing, including a tower body. A wind duct is provided at the top of the tower body. A dust filter and a fan are arranged from top to bottom in the inner cavity of the wind duct. A water supply box is fixedly installed on the upper surface of the inner wall of the tower body. One end of the water supply box is connected to a liquid inlet pipe. The other end of the liquid inlet pipe passes through the inner wall of the tower body and extends to its outer side. A rotating rod is inserted into the inside of the water supply box. Push plates are fixed on the left and right sides of the outer wall of the rotating rod. Nozzles are evenly arranged at the bottom of the water supply box. The bottom end of the rotating rod passes through the water supply box and is connected to a follower rod. A support rod is provided below the nozzle. A connecting rod is provided at the bottom of the support rod. A spiral disk is provided on the outer side of the connecting rod. A buffer hole is provided on the inner wall of the spiral disk. An air inlet is opened on the surface of the tower body. A louver is engaged at the air inlet.

[0006] It should be noted in the solution that the spiral disk is provided in several groups.

[0007] It is worth noting that the inner wall of the air inlet is also fixedly connected with a first filter and a second filter.

[0008] In a preferred embodiment, the louver is located to the left of the first filter, the first filter is engaged with the inner wall of the air inlet, and the thickness of the first filter is less than that of the second filter.

[0009] It should be noted in the plan that the liquid outlet of the tower body is fixedly connected to a liquid outlet pipe.

[0010] It is worth noting that a filter plate is inclinedly installed above the liquid outlet, and a slag discharge pipe is connected to the side wall of the tower body.

[0011] In a preferred embodiment, an inspection door is hinged to one side surface of the tower body, and the inspection door is provided with a handle.

[0012] Compared with the prior art, the crossflow cooling tower for concentrated milk processing provided by this utility model has at least the following beneficial effects:

[0013] 1. A rotating rod and a push plate are installed inside the water delivery box. When hot milk enters the water delivery box through the inlet pipe, the force of the milk flow pushes the push plate, which in turn drives the rotating rod and the follower rod to rotate. The rotating follower rod hits and disperses the milk sprayed from the nozzle, so that the milk can fully contact the cold air and prevent the milk from concentrating in one place, which would reduce the cooling effect.

[0014] 3. A spiral disc is installed below the nozzle to reduce the falling speed of the milk and at the same time increase the residence time of the cold air in the tower, so that the milk and the cold air can come into full contact and achieve a better cooling effect.

[0015] 2. By installing a dust filter and a fan at the top of the tower, the necessary airflow for cooling can be provided inside the tower. At the same time, an air inlet and louvers are installed to introduce outside air and gas into the tower to cool the milk left vertically. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0022] The core of this application is to provide a crossflow cooling tower for concentrated milk processing, which solves the problem that in the current crossflow cooling devices, milk cannot fully contact the air, and the air has a short residence time in the cooling tower and a fast discharge rate, resulting in low milk cooling efficiency.

Figure 2 This utility model provides a front sectional view of a crossflow cooling tower for concentrated milk processing. Figure 3 See the schematic diagram of the air inlet structure provided by this utility model. Figures 1 to 3 As stated above.

[0024] A crossflow cooling tower for concentrated milk processing includes a tower body 1, the size of which is set according to actual needs. A wind duct 2 is provided at the top of the tower body 1. A dust filter 3 and a fan 4 are arranged from top to bottom inside the wind duct 2. The fan 4 can provide the air force required for cooling inside the tower body 1, so that the milk can be cooled quickly. The dust filter 3 is provided on the upper surface of the fan 4 to prevent impurities in the outside air from entering the tower body 1. A water delivery box 6 is fixedly installed on the upper surface of the inner wall of the tower body 1. One end of the water delivery box 6 is connected to an inlet pipe 5, and the other end of the inlet pipe 5 passes through the inner wall of the tower body 1 and extends to its outer side. The other end of the inlet pipe 5 is connected to a delivery pump (not shown in the figure). The delivery pump can use the delivery pump to deliver milk to the water delivery box 6 through the inlet pipe 5. A rotating rod 7 is inserted inside the water delivery box 6. The rotating rod 7 is located in the middle of the inside of the water delivery box 6. Push plates 8 are fixed on the left and right sides of the outer wall of the rotating rod 7. When the push plates 8 rotate, they can drive the rotating rod 7 to rotate. The bottom of the water delivery box 6 is evenly provided with nozzles 10. Multiple nozzles 10 are connected to the water delivery box 6. The milk in the water delivery box 6 is sprayed downward through multiple nozzles 10. The bottom end of the rotating rod 7 passes through the water delivery box 6 and is connected to a follower rod 9. The follower rod 9 is fixedly connected to the rotating rod 7. In actual use, the delivery pump delivers milk through the inlet pipe 5 to the water box 6, and then sprays it downwards through multiple nozzles 10 at the bottom of the water box 6. The milk flowing in the water box 6 can push the push plate 8, which in turn drives the rotating rod 7 to rotate. The follower rod 9 fixed on the rotating rod 7 is driven to rotate. The rotating follower rod 9 hits and disperses the milk sprayed from the nozzles 10, so that the milk can fully contact the cold air and prevent the milk from concentrating in one place, which would reduce the cooling effect.

[0025] In the above embodiment, a support rod 11 is provided below the nozzle 10, a connecting rod 12 is provided at the bottom of the support rod 11, a spiral disk 13 is provided on the outer side of the connecting rod 12, and buffer holes 14 are provided on the inner wall of the spiral disk 13. Multiple sets of buffer holes 14 are provided, and the buffer holes 14 are equally spaced and embedded in the inner wall of the spiral disk 13. The spiral disk 13 is used to fully disperse the milk and ensure full contact with the air. An air inlet is provided on the surface of the tower body 1, and a louver 15 is engaged at the air inlet to introduce outside air and gas into the interior of the tower body 1, thereby cooling the vertically flowing milk.

[0026] To further achieve a better dispersion effect, preferably, the spiral disk 13 is provided in several groups. The several groups of spiral disks 13 can fully disperse the vertically flowing milk, while allowing the outside air to rise slowly, so that the outside cold air can come into full contact with the milk and achieve a better cooling effect.

[0027] Preferably, a first filter 16 and a second filter 17 are fixedly connected to the inner wall of the air inlet. The first filter 16 and the second filter 17 facilitate the filtration of fresh air entering the tower body 1.

[0028] Preferably, the louver 15 is located to the left of the first filter 16, the first filter 16 is engaged with the inner wall of the air inlet, and in order to facilitate the installation of the first filter 16, the thickness of the first filter 16 is less than that of the second filter 17.

[0029] In this embodiment, preferably, the outlet of the tower body 1 is fixedly connected to the outlet pipe 20, and the cooled milk in the tower body 1 is discharged through the outlet pipe 20.

[0030] To prevent impurities from being present in the cooled milk, preferably, a filter plate 18 is inclinedly arranged above the outlet, and a slag discharge pipe 19 is connected to the side wall of the tower body 1. The filtered milk in the tower body 1 is filtered by the filter plate 18, and impurities are discharged through the slag discharge pipe 19.

[0031] In this embodiment, preferably, a maintenance door 21 is hinged to one side surface of the tower body 1, and a handle 22 is provided on the maintenance door 21. The handle 22 and the maintenance door 21 facilitate the maintenance of the device.

[0032] The crossflow cooling tower for concentrated milk processing provided in this application operates on the following principle: a delivery pump pumps milk through an inlet pipe 5 to a water delivery box 6, which then sprays it downwards through multiple nozzles 10 at the bottom of the water delivery box 6. The flowing milk in the water delivery box 6 pushes a push plate 8, causing the push plate 8 to rotate a rotating rod 7. A follower rod 9 fixed to the rotating rod 7 is also rotated, and the rotating follower rod 9 disperses the milk sprayed from the nozzles 10. Several sets of spiral discs 13 can fully disperse the vertically flowing milk, while simultaneously causing the outside air to rise slowly, allowing the outside cold air to fully contact the milk. At the same time, the fan 4 is turned on, providing the necessary airflow for cooling inside the tower body 1. Fresh air filtered by the first filter screen 16 and the second filter screen 17 enters the tower body 1 through the air inlet, dissipating heat laterally from the passing milk.
