Abstract
The utility model discloses a circular roller screen which comprises a screen cylinder, a central shaft and a radiation-shaped steel support used for supporting the screen cylinder. The start end of the steel support is fixed on a protecting shaft sleeve arranged outside the central shaft. The circular roller screen is characterized in that a hitting device is arranged inside the circular roller screen. The hitting device comprises a hitting hammer and a hitting board which corresponds with each other. The circular roller screen has the advantages of being small in occupied space, low in investment cost, simple and convenient in craft arrangement, convenient to maintain, simple and easy to operate and the like. The circular roller screen is high in screening efficiency, smooth in feeding, not prone to plugging holes, strong in adapting capability to materials, and capable of screening materials which are strong in stickiness and humidity and dirty and of varied kinds. The circular roller screen is stable and reliable in running, and not prone to damaging a screening net, saves maintenance cost and prolongs service life of the screen net.
Description
Technical field
The utility model belongs to the motor-vibro screen that the building material machinery industry is used, and relates to a kind of round roller screen.
Background technology
At present round roller screen does not usually establish beating unit or beating unit is located at the outside.
If do not establish beating unit, prevent that sieve pore blockade from only depending on upset, the rolling of material in cylinder, the material that is stuck in the sieve aperture is ejected.This mode is low to the adaptive capacity of material, and the material of viscosity, high humidity, the character such as dirty, assorted is difficult for screening, and the selection of material is had certain limitation, and screening efficiency is not high.
If beating unit is located at the outside, ining contrast to the round roller screen of not establishing beating unit has increased exciting force to a certain extent, and the material adaptive capacity is strengthened to some extent, but drawback is that fragile screen cloth has reduced service life, increased the maintenance maintenance cost, moreover it is large to take up room, outward appearance lacks aesthetic feeling.
Summary of the invention
The utility model provides the round roller screen that a kind of screening efficiency is high, adaptable to material, be not easy to damage screen cloth in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Round roller screen of the present utility model comprises that the radial steel bracket of screen drum, central shaft, support screen drum, steel bracket top are fixed on the outer protective shaft sleeve of central shaft, and its special character is: its inside is equipped with beating unit.
Described beating unit comprises hammer and the punch panel of mutual correspondence, and punch panel is welded on the steel bracket end, with connecting rod, connects top and is hinged on the protective shaft sleeve of central shaft on the hammer.
The beneficial effects of the utility model are:
(1) take up room littlely, cost of investment reduces;
(2) technology arrangement is easy, installation, easy to maintenance, the characteristics such as operation walk away safety.
(3) exciting force is strong, and screening efficiency is high, and blanking is unobstructed, is difficult for plug-hole, adaptable to material, and the material of viscosity, high humidity, the various character such as dirty, assorted can both sieve.
(4) smooth running is reliable, is not easy to damage screen cloth, has saved the maintenance maintenance cost, prolongs screen cloth service life.
(5) reasonable in design, technique is advanced, compact conformation, good looking appearance are generous.
Description of drawings
Fig. 1 is structural representation of the present utility model.Fig. 2 is the local enlarged diagram of Fig. 1.
Among the figure, 1, central shaft; 2, protective shaft sleeve; 3, steel bracket; 4, hammer axis pin base; 5, connecting rod; 6, hammer; 7, punch panel; 8, screen drum.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Round roller screen of the present utility model comprises screen drum 8, central shaft 1, supports the radial steel bracket 3 of screen drum, and steel bracket top is fixed on the outer protective shaft sleeve 2 of central shaft, and circle roller screen inside is equipped with beating unit.Described beating unit comprises hammer 6 and the punch panel 7 of mutual correspondence, and punch panel is welded on steel bracket 3 ends, with connecting rod 5, connects top and is hinged on the protective shaft sleeve 2 of central shaft on the hammer.
The circle roller screen comprises sieve bucket and a sieve bucket internal structure, and sieve bucket inside arranges three groups of hammer devices, and the connecting rod of hammer is articulated on the protective shaft sleeve between the two steel bracket branches by bearing pin, and hammer can freely swing.Three groups of hammer axis pin bases 4 are welded on the protective shaft sleeve of sieve bucket 2 internal steel carriage center, protective shaft sleeve is by the connecting rod of the hinged hammer of bearing pin.In circle roller screen internal steel support welding punch panel 7.When the sieve bucket rotates, because the Action of Gravity Field of hammer 6, do not do with roller screen and be synchronized with the movement, when thereby the sieve bucket rotates, hammer 6 is constantly knocked the punch panel 7 that places on the steel bracket, thereby produces vibration, and the exciting force that produces is strong, the material that is stuck in sieve aperture or sticks on the sieve bucket is outwards ejected, guarantee that blanking is unobstructed.Punch panel 7 is used six groups, two punch panel about each hammer correspondence.When the circle roller screen clockwise rotated, hammer was knocked the punch panel in the side steel bracket branch, and when the circle roller screen rotated counterclockwise, hammer was knocked the punch panel in the opposite side steel bracket branch.
Claims (2)
1. round roller screen comprises the radial steel bracket of screen drum, central shaft, support screen drum, and steel bracket top is fixed on the outer protective shaft sleeve of central shaft, and it is characterized in that: its inside is equipped with beating unit.
2. round roller screen according to claim 1, it is characterized in that: beating unit comprises hammer and the punch panel of mutual correspondence, and punch panel is welded on the steel bracket end, with connecting rod, connects top and is hinged on the protective shaft sleeve of central shaft on the hammer.
