Description

Technical Field

[0001] This utility model relates to the field of centrifugal spray dryer technology, and in particular to a centrifugal spray dryer with enhanced heat exchange components. Background Technology

[0002] Centrifugal spray dryer is a common drying equipment. It uses centrifugal force to disperse liquid material into fine droplets, which then come into contact with hot air, causing the moisture in the droplets to evaporate rapidly, thereby obtaining a dried product. When using existing centrifugal spray dryers, the high-speed atomizer is easily clogged because the liquid material is not filtered. Therefore, centrifugal spray dryers with enhanced heat exchange components are needed. Chinese patent provides a centrifugal spray dryer, publication number CN210495261U, which includes a device fixing shell. A drying container is fixedly connected to the top of the inner cavity of the device fixing shell. A liquid storage tank is fixedly installed on one side of the top of the device fixing shell. An inlet pipe is inserted into the inside of the liquid storage tank. One end of the inlet pipe, which extends into the inside of the drying container, is fixedly connected to an atomizing head. A cylinder located on one side of the liquid storage tank is fixedly installed on the top of the device fixing shell.

[0003] The aforementioned centrifugal spray dryer can tightly adhere to the inner wall of the drying container through the outer surface of the elastic cloth. After the cylinder is started, it can scrape and clean the inner wall of the drying container, improving the cleaning ability of the device. However, when using this centrifugal spray dryer, the liquid material to be dried enters the drying tank without being filtered, which can easily cause the centrifugal atomizer in the drying tank to become clogged and damaged. Furthermore, when the dried powder enters the pipeline from the drying tower, sometimes the discharge speed is too fast and the powder cannot be discharged in time, which can easily cause the powder to accumulate in the pipeline and form a blockage, thus requiring the staff to clean the pipeline frequently. Utility Model Content

[0004] The main purpose of this invention is to provide a centrifugal spray dryer with enhanced heat exchange components, which can effectively solve the technical problems in the background art where liquid materials to be dried enter the drying tank without being filtered, which easily causes blockage and damage to the centrifugal atomizer in the drying tank, and when the dried powder enters the pipeline from the drying tower, sometimes the discharge speed is too fast and the powder is not discharged in time, which easily causes the powder to accumulate in the pipeline and form a blockage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A centrifugal spray dryer with enhanced heat exchange components includes a drying tank. A high-speed atomizer is fixedly installed on the top of the drying tank. An air inlet pipe is fixedly installed on the outer wall of the drying tank. An electric heater is fixedly installed at one end of the air inlet pipe. A peristaltic pump is fixedly installed on the top of the drying tank. A connecting pipe is fixedly installed on the right end of the outer wall of the peristaltic pump. One end of the connecting pipe is fixedly connected to the high-speed atomizer. A liquid inlet pipe is fixedly installed at the other end of the peristaltic pump. A liquid tank is fixedly installed at one end of the liquid inlet pipe.

[0006] As a further embodiment of this utility model, a first rotating block is fixedly installed on the outer wall of the liquid tank, a second rotating block is rotatably connected to the outer wall of the first rotating block, a tank cover is fixedly installed on the outer wall of the second rotating block, a motor is fixedly installed on the outer wall of the tank cover, and a stirring rod is fixedly installed through the outer wall of the tank cover at the output end of the motor.

[0007] As a further embodiment of this utility model, four support blocks are fixedly installed on the inner wall of the liquid tank, a first filter screen is provided on the top of the four support blocks, a second filter screen is provided on the top of the first filter screen, and the second filter screen is compatible with the first filter screen.

[0008] As a further embodiment of this utility model, a discharge pipe is fixedly installed at the bottom of the drying tank, and a cyclone separator is provided at one end of the discharge pipe, and one end of the discharge pipe is fixedly connected to the outer wall of the cyclone separator.

[0009] As a further embodiment of this utility model, a fixing block is provided at the bottom of the discharge pipe, and two electric push rods are fixedly installed on the top of the fixing block, with a support frame fixedly installed at the output end of the two electric push rods.

[0010] As a further embodiment of this utility model, connecting blocks are fixedly installed at the top and bottom of the support frame, and two striking rods are fixedly installed on the outer walls of the two connecting blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1) When the centrifugal spray dryer with enhanced heat exchange components adds liquid material to the feed tank, the motor output drives the stirring rod to stir the liquid material and filter it through the first and second filter screens. This makes the filtered liquid material less likely to clog the high-speed atomizer. Through the adaptive matching between the second and first filter screens, the second filter screen can fit with the first filter screen, and the first and second filter screens can be quickly disassembled and cleaned.

[0012] 2) This centrifugal spray dryer with enhanced heat exchange components can drive the support frame to move up and down through the output end of the electric push rod, which in turn drives the striking rod to strike the discharge pipe back and forth. This can prevent the processed powder from clogging the discharge pipe, effectively avoiding the problem of discharge pipe blockage. The automatic striking of the discharge pipe by the striking rod eliminates the tedious steps of manual cleaning, improves work efficiency, and reduces the burden on operators.
