Abstract

The utility model discloses a double rotary screen type material screening device. A one-level rotary screen is installed on the upper portion of a rack of the device. A second-level rotary screen is installed on the lower portion of the rack. A one-level screening delivery mechanism is installed on the rack which is between the one-level rotary screen and the second-level rotary screen. A second-level screening delivery mechanism is installed on the rack which is below the second-level rotary screen. The one-level rotary screen and the second-level rotary screen are both arranged in a sloped mode. The feeding end is higher than the discharging end. The feeding end of the one-level rotary screen is communicated with a raw material cabin through a one-level feeding pipe. Screen underflows of the one-level rotary screen enter into the feeding end of the second-level rotary screen through the one-level screening delivery mechanism and a second-level feeding pipe. Products with qualified granularity are screened in one time. Working efficiency is high. Diameter of the rotary screen is large and rotating speed is fast. Material width of materials in the rotary screen becomes wider clearly. A material flow is lengthened and screening ability is improved clearly when the materials are screened.

Description

Twin-roll sieve formula Supplying Sieving Mechanism
Technical field:
The utility model relates to a kind of production ceramsite sand material screening device, particularly relates to a kind of twin-roll sieve formula Supplying Sieving Mechanism.
Background technology:
When producing ceramsite sand, need first raw material to be sieved, make the satisfactory raw material of granule size enter next process, existing material screening apparatus structure is simple, function singleness, inefficiency, and, material screening device employing diameter is 1.5 meters rotary screen, power is the variable-frequency motor of 18.5kW-6 level, the rotary screen rotating speed is 523.8r/min, because semi-finished product screening amount is large, material is subjected to the formed material web of the little reason of rotary screen diameter narrow when screening, the material flow that forms when rotary screen rotates is less to cause the rotary screen wearing and tearing frequent, repairs a screen cloth in average three days, and a week is changed a screen cloth, maintenance capacity is more time-consuming, all is difficult to adapt to need of production from practicality and economy.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of uniqueness, high efficiency, screening effect is good and automaticity is high twin-roll sieve formula Supplying Sieving Mechanism of designing is provided.
The technical solution of the utility model is: a kind of twin-roll sieve formula Supplying Sieving Mechanism, contain organic frame, described upper rack is equipped with the one-level rotary screen, the bottom of described frame is equipped with the two stage cylinder sieve, on the described frame between described one-level rotary screen and the two stage cylinder sieve one-level separator conveyer structure is installed, on the described frame of described two stage cylinder sieve below secondary separator conveyer structure is installed, described one-level rotary screen and two stage cylinder sieve all are obliquely installed, feed end is higher than discharge end, the feed end of described one-level rotary screen is communicated with raw material cabin by the one-level feed pipe, and the screenings of described one-level rotary screen enters the feed end of described two stage cylinder sieve by described one-level separator conveyer structure and secondary feed tube.
The discharge end of described one-level rotary screen is connected with reject bin by the semi-finished product drain tank, and described reject bin bottom is equipped with pulverizer, and the discharging opening of described reject bin bottom pulverizer is corresponding with described secondary separator conveyer structure.
The discharge end of described two stage cylinder sieve is connected with the lower end of elevator by the finished product drain tank, and the upper end of elevator is connected with warehouse for finished product.
The beneficial effects of the utility model are:
1, the utility model adopts the twin-roll sieve, can disposable sieve out the qualified product of granularity, high efficiency, and the diameter of rotary screen is large, and rotating speed is high, material obviously broadens in the web of rotary screen the inside, and material flow lengthens during screening, and sieving capacity is obviously promoted.
2, the utility model rotary screen diameter reaches 2.2 meters, uses power to be the variable-frequency motor of 11kW-4 level, and the rotary screen rotating speed is 671.6r/min, its screening effect is good, and screen cloth is changed also to change from a week of old-fashioned screen(ing) machine and is once extended to replacing in three months once, and energy-saving and cost-reducing benefit is obvious.
3, the utility model blanking, screening, material loading adopt circulating technology chain, reduce the equipment overlapping investment, and automaticity is high, reduces the impact of human factor, reduces labour cost.
4, the utility model pulverizer can carry out the large granular materials that the one-level rotary screen is told the scene pulverizing, be convenient to circulate material loading and screening, all swivel links in the middle of reducing.
5, the utility model designs uniqueness, high efficiency, screening effect is good and automaticity is high, and it is applied widely, is particularly useful for firing of high-strength ceramsite sand, has good economic benefit after the popularization.
Description of drawings:
Fig. 1 is the structural representation of twin-roll sieve formula Supplying Sieving Mechanism.
