Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a high-speed centrifugal spray dryer. Background Technology

[0002] A high-speed centrifugal spray dryer is a device that uses a high-speed centrifugal atomizer to atomize liquid materials into tiny droplets, which are then rapidly dried into powder or granular products by contacting hot air in a parallel flow. It mainly uses different atomizers to spray solutions, emulsions, suspensions, or pastes containing moisture into fine droplets in the hot air inside the drying tower. As the droplets fall, the moisture is evaporated, resulting in powder or granular products.

[0003] Traditional spray drying equipment typically uses a straight up-and-down airflow during drying. The high-temperature airflow has a short residence time inside the equipment, and the gas dissipates heat quickly. There is a large temperature difference between the airflow entering and exiting the drying equipment. If large droplets need to be sprayed for drying, incomplete drying is likely to occur. After long-term operation, the high-temperature residual material is adsorbed on the inner wall of the dryer, which is difficult to clean. Long-term adsorption can also corrode the dryer, reducing its service life. To address this issue, we have proposed a high-speed centrifugal spray dryer. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed centrifugal spray dryer to solve the problem of incomplete drying mentioned in the background art.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This high-speed centrifugal spray dryer uses a controller to start a hot air blower to preheat the air. The heated gas is then introduced into the dryer body through the air inlet and outlet pipes. Raw materials are injected into the feed pipe, and the centrifugal sprayer is activated to atomize and spray the raw materials. The electric heating element is activated to heat the heating cone, thereby heating the interior of the dryer body. This replenishes the heat inside the drying cylinder, preventing a decrease in drying effect due to heat loss from the hot air and improving processing quality.

[0013] 2. After prolonged use, when a large amount of material adheres to the inner wall of this high-speed centrifugal spray dryer, the controller activates the cylinder, which moves the water storage tray. This causes the cleaning scraper to clean the adsorbed material. Simultaneously, the water pump draws clean water from the water tank through the water pipe and delivers it to the water storage tray via the telescopic cover. The water is then sprayed through the sprinkler nozzles to wash away the material adsorbed on the inner wall of the dryer. At the same time, the vibrator is activated to vibrate the dryer body, causing the material to fall off. This convenient operation facilitates the cleaning of adsorbed material and extends the dryer's service life. Attached Figure Description

[0030] In summary, after prolonged use, when a large amount of material adheres to the inner wall of the dryer, the controller 160 activates the cylinder 220, causing the cylinder 220 to move the water storage tray 221. This allows the cleaning scraper 223 to clean the adsorbed material. Simultaneously, the water pump 230 is activated to draw clean water from the water tank 140 through the water pipe 141, which is then transported to the water storage tray 221 via the telescopic cover pipe 231. The water is then sprayed through the sprinkler head 222 to rinse the material adsorbed on the inner wall of the dryer.

The raw material is injected into the feed pipe 211, the centrifugal sprayer 210 is activated to atomize and spray the raw material, and the electric heating element 131 is activated to heat the heating cone 130, thereby heating the interior of the dryer body 100. This replenishes the heat inside the drying cylinder and prevents a decrease in drying effect due to heat loss from the hot air. After prolonged use, when the dryer... When a large amount of material is adsorbed on the inner wall of the dryer, the cylinder 220 is started by the controller 160, which moves the water storage tray 221 so that the cleaning scraper 223 can clean the adsorbed material. At the same time, the water pump 230 is started to draw clean water from the water tank 140 through the water pipe 141 and deliver it to the water storage tray 221 through the telescopic cover pipe 231. The water is then sprayed through the water spray nozzle 222 to wash the material adsorbed on the inner wall of the dryer. At the same time, the vibrator 150 is started to drive the dryer body 100 to vibrate, causing the material to fall off. The operation is convenient and easy to clean the adsorbed material.

[0032] It should be noted that the hot air blower 111, electric heating element 131, vibrator 150, controller 160, centrifugal sprayer 210, cylinder 220, sprinkler head 222, and water pump 230 mentioned in the text are all existing technologies that can be found. The principle of the hot air blower 111 is: heating the air through an electric heating element, and then using a fan to blow the hot air out, thereby achieving the heating effect; the principle of the electric heating element 131 is: by connecting a power source to the terminal, the electricity is conducted through the terminal to the resistance wire, the resistance wire generates heat when energized, and then the heat is transferred through the highly thermally conductive magnesium oxide powder. The heat is conducted to the surface of the heating element 131, generating heat on the surface of the heating element 131. The principle of the vibrator 150 is as follows: the working part of the vibrator 150 is usually a rod-shaped hollow cylinder with an eccentric oscillator inside. Driven by the motor, the eccentric oscillator rotates at high speed, generating high-frequency micro-amplitude vibration. The principle of the controller 160 is as follows: the controller 160 includes a PLC and a memory. Specifically, when the PLC is running, the PLC performs a periodic cyclic scan according to the instruction step number or address number, based on the program coded by the user according to the control requirements and stored in the user program memory. If there is no jump... The instruction transfer process executes the user program sequentially, starting from the first instruction, until the program ends. Then, it returns to the first instruction and begins the next scan. During each scan, it also samples the input signals and refreshes the output status. The principle of the centrifugal sprayer 210 is as follows: The centrifugal sprayer 210 mainly consists of a spray chamber, a sprayer, and a hot air disc. The diameter of the spray chamber is related to the rotational speed of the centrifugal spray disc. The droplet diameter is inversely proportional to the rotational speed, and the droplet range is directly proportional to the droplet diameter. That is, the smaller the rotational speed, the larger the droplet range. The tower diameter increases with the range. The spray pitch increases with the increase of the spray torque; the principle of cylinder 220 is: power is generated inside cylinder 220 by compressed air, which pushes the piston rod to make reciprocating linear motion; the principle of sprinkler head 222 is: sprinkler head 222 is used in fire sprinkler system. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire; the principle of water pump 230 is: water pump 230 includes motor and impeller. The power of motor inside water pump 230 drives impeller to rotate, thereby converting power into liquid power, thereby generating flow force and transporting liquid from low pressure area to high pressure area.
