Description

Technical Field

[0001] The utility model relates to the technical field of powdered sugar screening, in particular to a cyclone powder screening device. Background Art

[0002] During the production of powdered sugar, the presence of sugar residues will affect the quality.

[0003] Therefore, a cyclone screen is usually used for screening operations; the material fed into the stationary horizontal screen cylinder by the auger is then pushed to the screen by the rotating paddle blades. Particles of appropriate size enter the discharge chute through the screen holes, and materials that are too large enter the discharge port.

[0004] At present, the feeding auger and the rotating shaft of the cyclone screen on the market share a single motor. The rotating speed of the rotating shaft of the cyclone screen is very fast, so the speed of the feeding auger is correspondingly very fast, which is likely to cause too fast feeding. Under this premise, the residence time of the material in the screen cylinder is too short, resulting in insufficient screening of the material, and a lot of fine material components are contained in the discharged coarse material.

[0005] For this reason, we propose a cyclone powder screening device to solve the existing problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a cyclone powder screening device aiming at the problems existing in the background art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a cyclone powder screening device, including a shaft rod, a machine shell, a screen cylinder, and a feeding cylinder. The screen cylinder is installed inside the machine shell. A shaft rod is rotatably installed inside the screen cylinder. Each paddle blade is equidistantly installed on the shaft rod. Annular air ducts are equidistantly opened on the shaft rod. A sealing plate is fixed at one end of the machine shell. An air blowing pipe is provided on the sealing plate. The air blowing pipe is rotatably connected to the annular air duct. A feeding cylinder is fixed at the other end of the machine shell. An auger rod is rotatably installed inside the feeding cylinder.

[0008] Preferably, a positioning plate is installed at one end of the screen cylinder. Each feeding port is equidistantly opened on the positioning plate;

[0009] The feeding cylinder and the screen cylinder are interconnected through the feeding ports;

[0010] One end of the shaft rod is rotatably installed on the positioning plate, and the other end of the shaft rod is rotatably installed on the sealing plate;

[0011] The shaft rod and the auger rod are interconnected with each other.

[0012] Preferably, a coarse material port and a fine material port are respectively opened on the lower surface of the machine shell;

[0013] The fine material opening is directly below the mesh cylinder;

[0014] The coarse material opening is located away from the mesh cylinder.

[0015] Preferably, a feed hopper is installed on the upper surface of the feed cylinder, and the feed hopper is interconnected with the feed cylinder;

[0016] A motor is fixed on the lower surface of the feed cylinder, and the output end of the motor is connected to the shaft end of the auger rod through a chain belt.

[0017] Preferably, support feet are installed on both the sealing plate and the feed cylinder, and the support feet are symmetrically distributed on the sealing plate and the feed cylinder.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] During the use of the cyclone powder screening device of the present utility model, the powdered sugar material to be screened can be introduced into the feed cylinder through the feed hopper, and under the rotational feeding of the auger rod, the powdered sugar enters the mesh cylinder through the feed port;

[0020] At this time, the paddle rotates driven by the shaft rod. The material fed into the stationary horizontal sieve cylinder by the auger is pushed onto the mesh cylinder under the action of the rotating paddle. The particles of appropriate size enter the machine shell through the sieve holes of the mesh cylinder and then are discharged through the fine material opening, while the materials with larger size are discharged from the coarse material opening after passing through the mesh cylinder;

[0021] During this process, an external compressed air source can be connected through the air supply pipe. The compressed air enters the shaft rod and then is ejected into the mesh cylinder through the annular air duct of the shaft rod. Under the action of the air pressure, the material is forced to pass through the mesh cylinder at an accelerated speed;

[0022] The present utility model uses the pressure of compressed air and the rotary paddle to separate sugar residues, realizes on-line powder screening during the production process, can effectively screen out foreign matters such as sugar residues, and ensures quality and safety.
