Description

Technical Field

[0001] The utility model relates to the technical field of spray drying towers, in particular to an anti-sticking wall spray drying tower for the production of compound amino acid powder. Background Art

[0002] A spray drying tower is a device that uses spray technology to atomize liquid materials and, through the contact of hot air with the atomized particles, enables them to quickly evaporate and form dry powder materials. It is widely used in fields such as biological pesticides, medicine, food microorganisms, chemical engineering, dyes, plastics, metallurgy, environmental protection, textiles, etc. In the pharmaceutical industry, spray drying technology can greatly simplify and shorten the process and time from traditional Chinese medicine extracts to semi-finished or finished preparations, improving production efficiency and drug quality.

[0003] During the production process of compound amino acid powder in a spray drying tower, due to reasons such as the product itself having a certain viscosity, too fast spray speed, or insufficient smoothness of the inner wall of the drying tower, the material adheres to the tower wall. Workers need to frequently stop the machine for cleaning, thereby reducing the overall production efficiency. The material adhering to the tower wall is also likely to fall off and mix into the finished product, resulting in a decrease in the quality of the final product. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, due to the lack of an anti-sticking wall structure, the material adhering to the tower wall reduces the product quality and production efficiency, and thus an anti-sticking wall spray drying tower for the production of compound amino acid powder is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an anti-sticking wall spray drying tower for the production of compound amino acid powder, including a main body mechanism, and a moving mechanism is fixedly sleeved on the outer surface wall of the main body mechanism;

[0006] The main body mechanism includes a spray drying tower main body. A chute is opened at the top of the inner wall of the spray drying tower main body. An installation hole one is opened at the top of the spray drying tower main body. A shaft hole is opened at the top of the spray drying tower main body. An installation hole two is opened at the top of the spray drying tower main body. A discharge pipe is fixedly inserted into the inner surface wall of the installation hole two. The bottom of the discharge pipe is fixedly communicated with an atomizer, and the top of the inner wall of the spray drying tower main body is fixedly connected to the top of the atomizer. The input end of the discharge pipe is fixedly communicated with a feeding pump. The input end of the feeding pump is fixedly communicated with a feeding pipe. A hot air distributor is fixedly installed on the top of the inner wall of the spray drying tower main body. The top of the hot air distributor is fixedly communicated with an air outlet pipe, and the inner surface wall of the installation hole one is fixedly inserted with the outer surface wall of the air outlet pipe. The input end of the air outlet pipe is fixedly communicated with a hot air blower. A motor is fixedly installed on the top of the spray drying tower main body. The output end of the motor is fixedly installed with a rotating shaft, and the inner surface wall of the shaft hole is movably inserted with the outer surface wall of the rotating shaft.

[0007] Preferably, a first gear is fixedly sleeved on the outer surface wall of the rotating shaft, and a second gear is meshed and connected to the outer surface wall of the first gear.

[0008] Preferably, a slider is fixedly installed at the top of the second gear, and the inner surface wall of the chute is movably embedded with the outer surface wall of the slider. A fixing rod is fixedly installed at the bottom of the second gear.

[0009] Preferably, a cleaning brush is fixedly installed between the outer surface walls of the fixing rods, and the outer surface wall of the cleaning brush is in contact with the inner surface wall of the spray drying tower main body.

[0010] Preferably, a group of flow guiding vanes are fixedly installed on the inner surface wall of the spray drying tower main body, and a flow guiding cover is fixedly installed between the outer surface walls of the group of flow guiding vanes.

[0011] Preferably, the moving mechanism includes a mounting plate, a chassis is fixedly installed at the bottom of the mounting plate, and a group of universal wheels are fixedly installed at the bottom of the chassis.

The bottom of the feeding pump is fixedly connected to the top of the mounting plate, and the bottom of the hot air blower is fixedly connected to the top of the mounting plate.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0014] In the present utility model, the hot air near the interior of the spray drying tower will enter the cavity between the flow guiding cover and the inner wall of the spray drying tower. Since the air outlet of this cavity is small, according to Bernoulli's principle, the flow rate of the hot air will increase and the temperature will decrease after passing through the flow guiding cover. At this time, the airflow can reduce the internal temperature and also isolate the droplets or finished products from the inner wall of the spray drying tower, thereby reducing the wall sticking situation. The motor can drive the cleaning brush to rotate through the rotating shaft and gears, sweeping down the materials adhered to the inner wall, reducing the time and cost of equipment cleaning and maintenance, improving the work efficiency, and also avoiding the adhered wall materials from entering the interior of the finished product, improving the uniformity and consistency of the product.

[0015] In the present utility model, under the action of the moving mechanism, the universal wheels at the bottom of the chassis can drive the device to move freely, enabling it to adapt to different production requirements and significantly improving the flexibility and convenience of production.

[0024] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0025] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments in the following disclosure.

[0026] Embodiment 1, as Figures 1-5 shown, the present utility model provides an anti-sticking wall spray drying tower for the production of compound amino acid powder, including a main body mechanism 1, and a moving mechanism 2 is fixedly sleeved on the outer wall of the main body mechanism 1;

[0027] The main body mechanism 1 includes a spray drying tower main body 101. A chute 102 is opened at the top inner wall of the spray drying tower main body 101. An installation hole one 103 is opened at the top of the spray drying tower main body 101. A shaft hole 104 is opened at the top of the spray drying tower main body 101. An installation hole two 105 is opened at the top of the spray drying tower main body 101. A discharge pipe 106 is fixedly inserted into the inner surface wall of the installation hole two 105. The bottom of the discharge pipe 106 is fixedly communicated with an atomizer 107, and the top of the inner wall of the spray drying tower main body 101 is fixedly connected to the top of the atomizer 107. The input end of the discharge pipe 106 is fixedly communicated with a feeding pump 108. The input end of the feeding pump 108 is fixedly communicated with a feeding pipe 109. A hot gas distributor 110 is fixedly installed on the top inner wall of the spray drying tower main body 101. The top of the hot gas distributor 110 is fixedly communicated with an air outlet pipe 111, and the inner surface wall of the installation hole one 103 is fixedly inserted with the outer surface wall of the air outlet pipe 111. The input end of the air outlet pipe 111 is fixedly communicated with a hot air blower 112. A motor 113 is fixedly installed on the top of the spray drying tower main body 101. The output end of the motor 113 is fixedly installed with a rotating shaft 114, and the inner surface wall of the shaft hole 104 is movably inserted with the outer surface wall of the rotating shaft 114. A gear one 115 is fixedly sleeved on the outer surface wall of the rotating shaft 114. A gear two 116 is meshed with the outer surface wall of the gear one 115. A slider 117 is fixedly installed on the top of the gear two 116, and the inner surface wall of the chute 102 is movably embedded with the outer surface wall of the slider 117. A fixing rod 118 is fixedly installed at the bottom of the gear two 116. A cleaning brush 119 is fixedly installed between the outer surface walls of the fixing rod 118, and the outer surface wall of the cleaning brush 119 is in contact with the inner surface wall of the spray drying tower main body 101. A group of guide vanes 120 are fixedly installed on the inner surface wall of the spray drying tower main body 101. A guide cover 121 is fixedly installed between the outer surface walls of the group of guide vanes 120.

[0028] The effect achieved by the entire Embodiment 1 is that when the spray drying tower is working, the feeding pump 108 starts to operate, sucking in external materials through the feeding pipe 109. Subsequently, the materials enter the inside of the discharge pipe 106 and then enter the atomizer 107 through the discharge pipe 106. The atomizer 107 evenly sprays the liquid materials. At this time, the hot air blower 112 starts together, sucking in external air into the hot air blower 112 and discharging the heated air. The heated air enters the hot air distributor 110 through the air outlet pipe 111. The hot air distributor 110 evenly sprays the hot air and mixes it with the liquid materials. Subsequently, the materials start to be heated and the water quickly evaporates, drying into finished products in a very short time. When the hot air descends inside the spray drying tower main body 101, a part of the air close to the inner wall of the spray drying tower main body 101 enters the cavity between the guide cover 121 and the inside of the spray drying tower main body 101. At this time, the guide vanes 120 make the air evenly distributed inside the cavity. Due to the special shape of the guide cover 121, the cavity structure is larger at the top and smaller at the bottom, and the air outlet is smaller. After the hot air with a higher temperature is discharged from the smaller air outlet, its flow rate will increase and the temperature will decrease accordingly, thereby reducing the temperature of the inner wall of the spray drying tower main body 101, preventing the cost from melting and sticking to the inner wall. Moreover, the air with a faster flow rate will form an air hood, preventing the spray from passing through the air hood and directly contacting the inner wall of the drying chamber, further avoiding the sticking of materials to the wall. When there is already material sticking to the inner wall of the spray drying tower main body 101, the worker can start the motor 113. The motor 113 drives the rotating shaft 114 to rotate inside the shaft hole 104, and the shaft hole 104 drives the first gear 115 to rotate. At this time, the second gear 116 meshed with the first gear 115 rotates together, driving the lower fixed rod 118 and the cleaning brush 119 to rotate to remove the materials on the inner wall. At this time, the slider 117 at the top of the second gear 116 starts to slide inside the chute 102 to avoid deviation in the moving direction. This device can greatly reduce the situation of material sticking to the wall, ensure that the materials are evenly heated during the drying process, avoid the contamination of products by residual materials, thereby improving the product quality. It can also automatically remove the materials sticking to the wall, thereby reducing the time for shutdown cleaning and improving the production efficiency.

[0029] Embodiment 2 is as Figures 2-5 shown. The moving mechanism 2 includes a mounting plate 201. A chassis 202 is fixedly installed at the bottom of the mounting plate 201. A set of universal wheels 203 are fixedly installed at the bottom of the chassis 202. The outer wall of the spray drying tower main body 101 is fixedly inserted into the inside of the mounting plate 201. The bottom of the feeding pump 108 is fixedly connected to the top of the mounting plate 201. The bottom of the hot air blower 112 is fixedly connected to the top of the mounting plate 201.

[0030] The effect achieved by the entire Embodiment 2 is that when the worker needs to move the device, only the mounting plate 201 and the chassis 202 need to be pushed. At this time, the universal wheels 203 at the bottom will drive the device to move freely, enabling it to quickly adjust its position according to different production requirements and adapt to different production environments and site layouts.

[0031] Working principle: When the production environment or site layout needs to be adjusted, the worker only needs to easily push the mounting plate 201 and the chassis 202, and the universal wheels 203 equipped at the bottom can make the entire device move flexibly and quickly adapt to various production requirements. When entering the working state, the feeding pump 108 is started, and the raw materials are sucked into the system through the feeding pipe 109. Subsequently, the raw materials flow through the discharge pipe 106 and are sent into the atomizer 107. The atomizer 107 evenly atomizes the liquid raw materials into tiny droplets. At the same time, the hot air blower 112 is started synchronously, sucking in the outside air and heating it to an appropriate temperature, and then sending the hot air into the hot air distributor 110 through the air outlet pipe 111. The hot air distributor 110 ensures the uniform distribution of the hot air, fully mixes with the atomized liquid materials, enabling the materials to evaporate moisture under heat in a very short time and quickly dry into finished products. During the drying process, a unique cavity structure is formed between the specially designed deflector 121 and the inner wall of the spray drying tower main body 101. This structure not only optimizes the flow path of the hot air but also, through the action of the guide vanes 120, makes the hot air near the inside of the spray drying tower main body 101 evenly distributed in the cavity. Since the cavity is larger at the top and smaller at the bottom and the air outlet is smaller, the discharged hot air has an accelerated flow rate and a reduced temperature. The low-temperature air effectively reduces the temperature of the inner wall of the spray drying tower main body 101, preventing the materials from melting and adhering. At the same time, the high-speed flowing air will also form a wind hood effect, preventing the spray from directly contacting the inner wall of the drying chamber and further reducing the phenomenon of material sticking to the wall. For the possible problem of adhesion on the inner wall, the device is also equipped with an automatic cleaning system. The worker only needs to start the motor 113, and the motor 113 drives the rotating shaft 114 to rotate in the shaft hole 104, thereby driving the gear one 115 and the meshing gear two 116 to rotate synchronously. The rotation of the gear two 116 drives the fixed rod 118 and the cleaning brush 119 to rotate, effectively removing the residual materials on the inner wall. During this process, the slider 117 at the top of the gear two 116 slides stably in the chute 102, ensuring that the cleaning process has no deviation.

[0032] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
