Description

Technical Field

[0001] This utility model relates to the field of atomization device technology, specifically to an atomization device for a centrifugal spray dryer. Background Technology

[0002] Color pastes for coloring fiber dopes are produced by adding color pastes to fiber dopes to directly prepare colored fibers. Since the pigment content in color pastes is generally 30-60%, with the remainder being substances that cannot contribute to coloring, their transportation and storage costs are relatively high. Dry powder or granular pigment formulations, on the other hand, have a significant advantage in storage stability compared to color pastes. Self-dispersible pigments, in particular, can be quickly dispersed in the work medium through simple stirring or shaking, a relatively easy process that is highly advantageous for the direct coloring of fiber dopes. Furthermore, surface-treated pigments have increased steric hindrance between particles, reducing the likelihood of agglomeration and resulting in higher stability and lower fineness.

[0003] Spray drying is the most widely used process in liquid processing and drying industries. It is best suited for producing powdered or granular solid products from solutions, emulsions, suspensions, and pastes of liquid raw materials. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product must meet precise standards.

[0004] A spray dryer atomizing device, as described in patent application number 202020641859.1, includes a dryer body. A motor housing is fixedly connected to the center of the top of the dryer body. A motor is housed inside the motor housing. A motor shaft is rotatably connected to the output end of the motor. One end of the motor shaft extends into the interior of the dryer body, and a collar is fitted onto one end of the motor shaft. A rotating rod is inserted into the collar. In this spray dryer atomizing device, the raw water inside the spray nozzle is diverted. Through the high-speed rotation of the first and second blades, the diverted raw water comes into contact with the first and second blades, breaking the raw water into extremely small water particles, thereby achieving an atomization effect.

[0005] Because fiber pigments contain some large solid particles, they can easily cause blockage at the nozzle of the atomizing spray disc. Furthermore, different fiber pigments have different viscosities, resulting in poor atomization effects and inconsistent atomized particle sizes, which affects drying efficiency and product quality. To address this, we propose an atomization device for a centrifugal spray dryer. Utility Model Content

[0006] The technical problem this invention aims to solve is to overcome existing defects and provide an atomization device for a centrifugal spray dryer. By integrating an ultrasonic generator and a transducer, high-frequency vibration assists in droplet breakage, improving atomization uniformity. A heating tube is used to heat the fiber pigment paste, thereby enhancing the atomization effect of high-viscosity fiber pigment paste. Furthermore, a circulating filtration system is employed to circulate and filter the fiber pigment paste, while a stirring rack continuously agitates it, removing large solid particles to prevent them from affecting subsequent atomization. This effectively solves the problems in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an atomizing device for a centrifugal spray dryer, comprising a tank and an inlet pipe; Tank body: A liquid pump is fixed on the bottom surface inside the tank. The outlet of the liquid pump is connected to one end of the delivery pipe. The other end of the delivery pipe is inserted and installed into the liquid inlet on the top surface of the fixed plate. A frame is fixed on the top surface of the fixed plate. A main motor is installed on the top surface of the frame. The output shaft of the main motor is connected to the top end of the fixed shaft. The bottom end of the fixed shaft is fixedly connected to the inside of the atomizing spray disc. The inner wall of the atomizing spray disc is slidably installed on the outer side of the fixed plate. The liquid inlet pipe is connected and installed on the front side of the top surface of the tank body. An auxiliary unit is provided on the top surface of the tank body. A circulation unit is provided on the side of the tank body. The system also includes a controller, which is fixed to the bottom of the front side of the tank. The input terminals of the liquid pump and the main motor are electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0008] The liquid pump is started to transport the fiber pigment inside the tank to the interior of the atomizing spray disc. The main motor is started to drive the atomizing spray disc to rotate rapidly so that the fiber pigment is atomized and sprayed out through the atomizing nozzles on its surface.

[0009] Furthermore, the auxiliary unit includes a heating tube, a placement seat, a temperature controller, an ultrasonic generator, and a transducer. There are two placement seats, each fixed to one side of the top surface of the tank. A heating tube is inserted into the interior of each placement seat. The temperature controller is fixed to the front side of the tank. The ultrasonic generator is mounted on the surface of the external dryer. The transducer is fixed to the top surface inside the fixed plate. The input end of the transducer is electrically connected to the output end of the ultrasonic generator. The input end of the heating tube is electrically connected to the output end of the temperature controller. The input ends of the ultrasonic generator and the temperature controller are electrically connected to the output end of the controller. Activating the ultrasonic generator, in conjunction with the transducer, causes the ultrasonic waves to break the fiber pigment inside the atomizing spray plate into tiny droplets. This, combined with centrifugal atomization, makes the fiber pigment atomization more uniform. Simultaneously, the temperature controller can be activated to heat the fiber pigment inside the tank, thereby improving the atomization effect on high-viscosity liquids.

[0010] Furthermore, the circulation unit includes a filter cartridge, a fixing plate, a housing, a bracket, a negative pressure pump, and a suction pipe. The bracket is fixed to the top of the left and right sides of the tank. The housing is placed inside the bracket, and the fixing plate is fixed inside the housing. The filter cartridge is inserted into the through hole on the surface of the fixing plate. The liquid outlet shell of the housing is inserted into the liquid inlet on the side of the tank. The negative pressure pump is fixed to the outer side of the housing. The suction pipe is installed in a groove on the bottom surface inside the tank. The liquid outlet of the suction pipe is connected to the liquid inlet of the negative pressure pump. The input end of the negative pressure pump is electrically connected to the output end of the controller. When the negative pressure pump is started, the fiber pigment inside the tank is sucked into the housing through the suction pipe, and the filter cartridge filters out large solid particles in the fiber pigment to prevent large solid particles from entering the atomizing spray plate and causing blockage.

[0011] Furthermore, the circulation unit also includes an auxiliary motor, a support, a stirring shaft, and a stirring frame. The support is fixed to the top surface of the tank, and the auxiliary motor is installed on the top surface of the support. The output shaft of the auxiliary motor is connected to the top end of the stirring shaft, and the bottom end of the stirring shaft is connected to the middle of the top surface of the stirring frame. The input end of the auxiliary motor is electrically connected to the output end of the controller. The auxiliary motor drives the stirring frame to continuously stir the fiber pigment inside the tank, thereby preventing the fiber pigment from settling.

[0012] Furthermore, it also includes an anti-stick layer and a corrosion-resistant coating. The anti-stick layer is set on the inner wall of the tank, and the corrosion-resistant coating is polytetrafluoroethylene. The outer side of the anti-stick layer is coated with a corrosion-resistant coating. The anti-stick layer can reduce material sticking to the wall, thereby reducing the difficulty of cleaning. At the same time, the corrosion-resistant coating resists chemical corrosion, so as to be suitable for the use of a variety of materials.

[0013] Furthermore, it also includes a temperature sensor, which is fixed to the rear side of the top surface of the tank. The output end of the temperature sensor is electrically connected to the input end of the controller. The temperature sensor can detect the temperature of the fiber pigment inside the tank, thereby adjusting the temperature in a timely manner.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The atomization device of this centrifugal spray dryer has the following advantages: 1. By activating the ultrasonic generator and transducer, the ultrasonic waves break the fiber pigment inside the atomizing spray plate into tiny droplets. This, combined with centrifugal atomization, makes the fiber pigment atomization more uniform. At the same time, the temperature controller can be activated to heat the fiber pigment inside the tank through the heating tube, thereby improving the atomization effect on high-viscosity liquids.

[0015] 2. By starting the negative pressure pump, the fiber pigment from inside the tank is drawn into the container through the suction pipe. A filter cartridge filters out large solid particles in the pigment to prevent them from entering the atomizing spray plate and causing blockage. Meanwhile, the auxiliary motor drives the stirring frame to continuously agitate the fiber pigment inside the tank, thus preventing sedimentation. 3. The non-stick layer reduces material adhesion to the wall, making cleaning easier, while the corrosion-resistant coating resists chemical corrosion, making it suitable for use with a variety of materials.
