Abstract
The utility model discloses a grain powder grading device which comprises an annular container with a coarse grain discharge outlet, a feed pipe and a fine grain discharge pipe. A rotating filter screen part is arranged in the container and rotates at high speed to form an annular filter screen, fine powder passes the annular filter screen into the fine powder discharge pipe and is conveyed to a fine powder collector through airflow, discharged grain of the fine powder can be controlled by adjusting rotation speed of the rotating filler screen part, and coarse powder which cannot pass the annular filter screen can be fed back for smashing again by a smasher. The grain powder grading device has the advantages that grain fineness can be selected, integral production efficiency is high, and labor intensity is low.
Description
Technical field
The utility model relates to the grain processing field, is specifically related to a kind of cereal powder elutriating apparatus.
Background technology
Aspect grain processing, often need to pulverize to obtain the cereal powder to cereal such as rice, corn, glutinous rice, soybean, satisfy the requirement of food production, the grain grinding method that adopts at present is mainly two kinds of dry pulverization process and wet pulverizings.Dry pulverization process is to adopt the size reduction machineries such as powder beater, Raymond mill cereal directly to be beaten (mill) powder, although crush efficiency is high, but granularity is even not, grain fineness is also inadequate, need to sieve with screen cloth, will sieve particle and return to the pulverizer pulverizing, screen cloth very easily stops up, need often cleaning, affected integral production efficient.Wet pulverizing is namely to adopt the size reduction machineries such as fiberizer, ball mill that cereal is worn into slurry, then slurry press dewatering, oven dry, although grain fineness is enough, the production cycle is long, and integral production efficient is not high, and labour intensity is large.
The utility model content
For above-mentioned the deficiencies in the prior art, a kind of cereal powder elutriating apparatus has been proposed.Adopt this device not only to guarantee the high efficiency of grain grinding, needing can also avoid the often defective of cleaning screen cloth, the grain fineness of cereal powder can be selected, and integral production efficient is high, and labour intensity is little.
The below is the concrete narration to this technical scheme.
A kind of cereal powder elutriating apparatus comprises that there is lower opening portion on top with the toroidal container of the oblique coarse grain discharging opening of off-axis, by the rotary sieve parts that rotating shaft and rotary sieve consist of, feed pipe, particulate discharge nozzle.The upper opening size of toroidal container is less than the top radial dimension of toroidal container, the top radial dimension of rotary sieve is greater than the upper opening size of toroidal container, the particulate discharge nozzle docks with the upper opening sealing of toroidal container, rotating shaft passes the particulate discharge nozzle along the axis of toroidal container, rotary sieve is placed in toroidal container and makes its top near the upper opening of toroidal container and do not touch, feed pipe passes chamber wall and is tightly connected with it from the container bottom along the axis of toroidal container, and the rotary sieve parts are driven by external impetus.
Described rotary sieve is the squirrel-cage spoke structure of an end opening, and the opening that rotating shaft passes rotary sieve is fastenedly connected along the axis of rotary sieve and the bottom of rotary sieve, and the spoke of rotary sieve is circle or flat bonding jumper.
The profile of rotary sieve is cylindrical body or up big and down small truncated cone body, and the bottom of rotary sieve is equipped with a bullet object, and the bottom of bullet object bottom and rotary sieve is fastenedly connected.
Described feed pipe also can be made of length-adjustable multiple-segment telescopic tube, and telescoping tube is flexible to the inside of toroidal container.
This gradation device has grain fineness can be selected, and integral production efficient is high, the advantage that labour intensity is little.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
A kind of cereal powder elutriating apparatus comprises that there is lower opening portion on top with the toroidal container 6 of the oblique coarse grain discharging opening of off-axis, by the rotary sieve parts that rotating shaft 1 and rotary sieve 4 consist of, feed pipe 7, particulate discharge nozzle 3.the upper opening size of toroidal container 6 is less than its top radial dimension, the top radial dimension of rotary sieve 4 is greater than the upper opening size of toroidal container 6, particulate discharge nozzle 3 docks with the upper opening sealing of toroidal container 6, rotating shaft 1 passes particulate discharge nozzle 2 along the axis of toroidal container 6, rotary sieve 4 is placed in toroidal container 6, the top of rotary sieve 4 is near upper opening place's inwall of toroidal container 6 and do not touch, feed pipe 7 passes chamber wall and is tightly connected with it from the toroidal container bottom along the axis of toroidal container 6, the rotary sieve parts are driven by external impetus.
Rotary sieve 4 is the squirrel-cage spoke structure of an end opening, and the opening that rotating shaft 1 passes rotary sieve is fastenedly connected along the axis of rotary sieve 4 and the bottom of rotary sieve, rotary sieve 4 rotate to be the circular metal bar.The profile of rotary sieve 4 is up big and down small truncated cone body, and the bottom of rotary sieve 4 is equipped with a bullet object 5, and the bottom of bullet object bottom and rotary sieve is fastenedly connected.
Feed pipe 7 is made of length-adjustable two joint telescoping tubes, and telescoping tube is flexible to the inside of toroidal container.
Cereal is after pulverizer is pulverized, and powder is carried by fan airflow, in the feed pipe access to plant of cereal powder elutriating apparatus, and particulate discharge nozzle external air extractor, the rotary sieve parts drive High Rotation Speed by external impetus, form annular filter screen.Fine powder passes annular filter screen and enters the particulate discharge nozzle via its upper opening, and it is stand-by to be delivered to fine powder collector by air-flow.The rotating speed of adjusting the rotary sieve parts can be controlled the discharging-material size of fine powder, can't pass the meal of annular filter screen and again send the pulverizer pulverizing back to via the coarse grain discharging opening.
