Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of milk powder spray drying, in particular to a milk powder spray drying tower. Background Art
[0002] Milk powder spray drying device is an industrial equipment specially used to convert liquid milk or milk concentrate into milk powder. The core of this device is to use spray drying technology to atomize liquid milk or concentrate into tiny droplets, and quickly exchange heat and mass with hot air, so as to quickly evaporate the water in the droplets and finally obtain milk powder products.
[0003] The current existing technology is that liquid milk is transported to the top of the milk powder spray drying tower through a pipeline, and the liquid milk is sprayed out in the form of small droplets in the drying chamber through an atomizer. The high-temperature air in the drying chamber heats and dries the liquid milk to form dry milk powder.
[0004] In the actual production process, after the small droplets sprayed by the atomizer dry into milk powder, some of them will be adsorbed on the side walls of the drying chamber and are difficult to clean. If they are not cleaned for a long time, a large amount of milk powder will accumulate on the side walls of the drying chamber, the internal space of the drying chamber will be reduced, and the space for the milk to pass through in the drying chamber will become smaller, resulting in some milk not being completely dried. The milk powder that is not completely dried will clump and accumulate at the discharge port, causing the discharge port to be blocked.
[0005] Therefore, a milk powder spray drying tower is proposed in view of the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0030] Specific examples are given below.
[0031] See also Figure 1-Figure 4The utility model provides a milk powder spray drying tower, comprising a supporting leg 1; a drying chamber 2, fixedly mounted on the top of the supporting leg 1; a spraying mechanism 3, fixedly mounted on the top of the drying chamber 2; a cleaning mechanism 4, fixedly mounted on the middle of the upper end of the drying chamber 2; an air intake mechanism 5, mounted around the outer surface of the drying chamber 2; an air outlet mechanism 6, fixedly mounted on one side of the outer surface of the drying chamber 2;
[0032] The cleaning mechanism 4 includes a motor 41, which is fixedly mounted in the middle of the upper end of the drying chamber 2. The output shaft of the motor 41 penetrates and is rotatably mounted on the top wall of the drying chamber 2. The output shaft of the motor 41 is fixedly connected to a first electric telescopic rod 42. A support plate 43 is fixedly connected to the bottom of the first electric telescopic rod 42. A slider 45 is slidably connected to the inner surface of the support plate 43. A connecting rod 46 is fixedly connected to one side of the slider 45. A scraper 47 is fixedly connected to one end of the connecting rod 46.
[0033] The bottom of the support plate 43 is provided with a groove 431, the inner surface of the groove 431 is fixedly mounted with a second electric telescopic rod 44, the slider 45 is fixedly mounted at one end of the second electric telescopic rod 44, the slider 45 is slidably mounted on the inner surface of the groove 431, a triangular prism 49 is fixedly mounted on the top of the support plate 43, and a stirring block 48 is fixedly mounted on the bottom of the scraper 47;
[0034] The spraying mechanism 3 includes four feed pipes 31, which are fixedly installed on the top of the drying chamber 2. One end of the feed pipe 31 passes through the top wall of the drying chamber 2 and is fixedly connected to a spray head 32. The top of the feed pipe 31 is fixedly connected to a storage box 33, and the top of the storage box 33 is fixedly connected to a feed pipe 34.
[0035] The milk liquid sprayed from the spraying mechanism 3 is dried in the drying chamber 2 to become a dry milk powder state, but some of the milk powder will adhere to the inner wall of the drying chamber 2, and the milk powder will be discharged at the bottom of the drying chamber 2, and the milk powder may be blocked at the bottom of the drying chamber.
[0036] First, the milk enters the storage box 33 through the feeding pipe 34, and the milk in the storage box 33 is atomized by the spray head 32 through the feeding pipe 31 and then sprayed out. The air inlet mechanism 5 supplies air to the inner cavity of the drying chamber 2. The air inlet mechanism 5 supplies high-temperature air to the drying chamber 2. Therefore, when the atomized milk is sprayed out, it is dried into milk powder. Part of the milk powder sticks to the inner wall of the drying chamber 2. The motor 41 drives the first electric telescopic rod 42 to rotate. The first electric telescopic rod 42 can move up and down with the support plate 43, and the second electric telescopic rod 44 can push the slider 45, so that the scraper 47 is close to the inner wall of the drying chamber 2. When the motor 41 rotates, the scraper 47 can scrape along the inner wall of the drying chamber 2 to scrape the milk powder on the inner wall of the drying chamber 2 to the bottom of the drying chamber 2. The first electric telescopic rod 42 can adjust the position of the scraper 47 by contraction and extension, so as to achieve the purpose of scraping off the milk powder stuck on the inner wall of the entire drying chamber 2.
[0037] When the second electric telescopic rod 44 contracts, the first electric telescopic rod 42 extends and can contact the milk powder at the bottom of the drying chamber 2 with the stirring block 48 through the scraper 47. The milk powder at the bottom of the drying chamber 2 is stirred by the rotation of the motor 41 to prevent the milk powder from accumulating at the bottom of the drying chamber 2 so that the milk powder cannot be discharged from the bottom of the drying chamber 2. Air is input into the drying chamber 2 through the air intake mechanism 5 and the air in the drying chamber 2 needs to be discharged. The air in the drying chamber 2 can be discharged through the air outlet mechanism 6.
[0038] Further, such as Figure 4 As shown, the air intake mechanism 5 includes an air heater 51, which is fixedly installed on one side of the top of the drying chamber 2. The outer surface of the air heater 51 is fixedly connected to a first air outlet pipe 52. The inner cavity of the air heater 51 is penetrated by an air supply pipe 53. The outer surface of the air supply pipe 53 is fixedly connected to four air intake pipes 54, and the four air intake pipes 54 all penetrate into the inner cavity of the drying chamber 2.
[0039] Since there are four spray heads 32, in order to dry the atomized milk in time, each spray head 32 is installed with an air intake pipe 54. The air sucked in from the outside is heated by the air heater 51 and then sprayed into the drying chamber 2 through the air intake pipe 54, so that the drying chamber 2 is always kept at a high temperature.
[0040] Further, such as Figure 4 As shown, the air outlet mechanism 6 includes a second air outlet pipe 61, which is fixedly installed on one side of the outer surface of the drying chamber 2 and passes through the inner cavity of the drying chamber 2. One end of the second air outlet pipe 61 is fixedly connected to a cyclone dust collector 62, and the top of the cyclone dust collector 62 is fixedly connected to a third air outlet pipe 63. The bottom of the cyclone dust collector 62 is fixedly connected to a slag inlet pipe 64, and the slag inlet pipe 64 passes through the inner cavity of the drying chamber 2.
[0041] In the process of discharging the air in the drying chamber 2, some milk powder will be mixed in the discharged air. The cyclone dust collector 62 is a machine that uses a rotating impeller to accelerate the dust-containing gas and throw it to the surroundings to achieve the purpose of dust removal. The dust-containing airflow enters along the tangential direction after the air inlet pipe 54, and the small particles in the airflow make a spiral motion downward, and the gas is discharged upward. In this milk powder drying tower, the gas in the drying chamber 2 enters the cyclone dust collector 62 through the second air outlet pipe 61, and the milk powder mixed in the air makes a spiral motion downward. The extracted air is discharged through the third air outlet pipe 63, and the milk powder falling downward will fall into the residue inlet pipe 64, and return to the drying chamber 2 again through the residue inlet pipe 64, waiting to be collected.
[0042] Further, such as Figure 2 and Figure 4 As shown, the spray head 32 and the air inlet pipe 54 are located at the same horizontal height, and the slag inlet pipe 64 is arranged at an angle.
[0043] In order to prevent the milk from being dried into milk powder particles in time after being sprayed from the spray head 32, the air outlet position of the air inlet pipe 54 in the drying chamber 2 is designed to be at the same height as the position where the atomized milk is sprayed from the spray head 32, so that the milk that has just been atomized and sprayed can be immediately dried into milk powder, and the milk powder separated by the cyclone dust collector 62 enters the drying chamber 2 again along the residue inlet pipe 64, which is convenient for the subsequent centralized collection of the milk powder. The inclined residue inlet pipe 64 can make the milk powder naturally slide into the drying chamber 2.
[0044] Working principle: First, the air heater 51 replaces the air in the drying chamber 2 with high-temperature air, and continuously inputs high-temperature air into the drying chamber 2, and the milk is atomized through the spray head 32 and sprayed into the drying chamber 2. The atomized milk is quickly dried into milk powder, and the motor 41 drives the scraper 47 to scrape off the milk powder adhering to the inner wall of the drying chamber 2. Through the cooperation of the first electric telescopic rod 42 and the second electric telescopic rod 44, the stirring block 48 can also stir the milk powder concentrated at the bottom of the drying chamber 2 to prevent the milk powder from accumulating and unable to flow out of the drying chamber 2.
[0045] The milk powder mixed with the air drawn out of the drying chamber 2 can be collected again into the drying chamber 2 by the cyclone dust collector 62, thus avoiding the waste of milk powder.
[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
