Description

Technical Field

[0001] The utility model belongs to the technical field of finished powder in a drying tower, in particular to a cooling device for finished powder in a drying tower. Background Art

[0002] The finished powder of the drying tower is usually produced by spray drying the raw materials. First, the raw materials are prepared into a slurry or solution of a certain concentration and property, and then atomized into fine droplets by a spray device and sent into the drying tower. In the drying tower, the hot air is fully in contact with the droplets, so that the water in the droplets evaporates rapidly, and finally forms dry powder particles. However, after the production is completed, it is inconvenient to cool it quickly. This problem brings many disadvantages. First, the slow cooling prolongs the time of the entire production process. The finished powder that could be quickly processed after drying has to wait longer due to the slow cooling, which makes the operation cycle of the equipment longer and reduces the production batches that can be completed within the working time. The slow cooling makes it impossible to closely connect the various links on the production line. For example, the subsequent screening, packaging and other processes are paused because of waiting for the finished powder to cool down, and smooth continuous operation cannot be formed, which seriously affects the overall production rhythm. Secondly, due to the slow cooling, unexpected situations may occur in the production process, such as powder agglomeration and adhesion, which require additional processing time to solve these problems, further reducing production efficiency. In order to solve this problem, it is urgent to develop a cooling device for the finished powder of the drying tower. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a finished powder cooling device for a drying tower, comprising: a cooling tank, a feed valve and a discharge valve, a feed valve is installed on the upper right side of the cooling tank, a discharge valve is installed on the lower left side thereof, an exhaust pipe is installed on the upper left side of the cooling tank, two axial flow fans are installed inside the exhaust pipe, and a powder filter plate is installed on the right side of the exhaust pipe;

[0023] A rotating tube is provided in the middle of the cooling tank, and multiple jet heads are installed on the left and right sides of the rotating tube. A driving motor is installed in the middle of the upper part of the cooling tank, and a sealed bearing is installed in the middle of the lower part of the cooling tank. The output shaft of the driving motor is connected to the upper end of the rotating tube.

[0024] The lower end of the rotating tube passes through the middle of the sealed bearing and is connected to a rotating joint. Both sides of the left side of the rotating tube are respectively connected to multiple toggle plates. A base is provided under the cooling tank, and an air pump is provided on the right side above the base. The air pump is connected to the bottom of the rotating joint through an inflation pipe.

[0025] The exhaust pipe is connected to the interior of the cooling tank, and the filter plate is made of polyester fiber.

[0026] The feed valve and the discharge valve are both connected to the interior of the cooling tank, and the cooling tank is made of aluminum.

[0027] The inner side of the sealed bearing is fixed to the outer wall of the rotating pipe, and both the feed valve and the discharge valve are large-diameter electric valves.

[0028] A fixing ring is installed on the outer side below the cooling tank, and the fixing ring is connected to the base through three support rods below.

[0029] The lower surface of the lowermost dialing plate contacts the inner bottom of the cooling tank. The dialing plate is of a rectangular structure. The left axial flow fan exhausts air outwards, and the right axial flow fan blows air inwards.

[0030] Please refer to Figures 1 to 4 , as the first embodiment of the present utility model: In actual use, the feed valve 2 needs to be connected to the discharge port of the drying tower. After production is completed, the finished powder can smoothly enter the cooling tank 1 through the feed valve 2. At the same time, the driving motor 3 can be started to drive the rotating pipe 13 to rotate at a constant speed. The rotating pipe 13 then drives a plurality of dialing plates 15 to rotate synchronously, fully stirring the finished powder in the cooling tank 1 to make it evenly dispersed, greatly improving the heat dissipation efficiency. At the same time, the air pump 10 can be started synchronously. The air pump 10 transmits gas to the rotary joint 16 through the air charging pipe 11. Then the gas is transmitted to a plurality of jet nozzles 14 through the rotating pipe 13 and ejected from the jet nozzles 14 into the interior of the cooling tank 1, so that the finished powder in the stirring process can be lifted, further promoting the full dispersion of the finished powder, thereby further improving the heat dissipation efficiency of the finished powder. While the rotating pipe 13 rotates, it can drive the inner side of the sealed bearing 17 to rotate.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , as the second embodiment of the present utility model: According to the further elaboration of the first embodiment, during the process of the finished powder being dispersed and lifted, the left axial flow fan 5 is started. At this time, the left axial flow fan 5 can effectively discharge the heat mixed with the finished powder inside the cooling tank 1 to the outside through the exhaust cylinder 4. When the air and the finished powder pass through the powder filtering plate 12 together, the powder filtering plate 12 can play a filtering role and intercept the finished powder mixed in the air to prevent it from being discharged to the outside together with the air. If the finished powder clogs the powder filtering plate 12 and causes the exhaust to be not smooth enough, the right axial flow fan 5 can be started. The right axial flow fan 5 can blow air towards the powder filtering plate 12, and then can blow off the finished powder clogging at the powder filtering plate 12, so that the powder filtering plate 12 can remain unblocked and smoothly filter the air. Through the above steps, the final effect is that the finished powder can be quickly cooled and dissipated. After the cooling operation is completed, the discharge valve 6 can be opened to discharge the cooled finished powder to the outside.
