Abstract
The utility model relates to an octal squirrel cage crushing screening equipment used to continuously crush and screen the old sand in a casting workshop. The outer layer consists of an octal screen; the inner layer has a screen body with a circular cross section; the screen body is welded with a guide block; the aperture of the screen body is larger than the aperture of the octal screen. The oil sand block enters the rotating screen body through the material inlet and is then lifted and thrown down as the screen body rotates; thus the oil sand block is crushed; the oil sand enters the octal screen after being divided by the crushing screen; and the oil sand is crushed for a second time by colliding and rubbing against the octal screen; thereby, the device realizes the function of two-time screening with one piece of equipment. The utility model has the advantages of the stable and reliable quality, the balanced operation and the realization of the two-time screening.
Description
(1) technical field
The utility model belongs to the technical field of broken screening installation, the broken screening installation of particularly a kind of anistree squirrel-cage.
(2) background technology
In the casting sand screening installation, generally use the broken sieve apparatus of cylinder.The cylinder of this kind equipment generally is to be rolled by the steel plate punching to be welded, if meet factors such as old sand moisture is higher, the sieve aperture of cylinder is easy to be blocked by old sand group, and screening installation was lost efficacy, and does not reach the purpose of screening in operation process.
(3) summary of the invention
The utility model is at the deficiency of cylinder disintegrating apparatus, designed that a kind of steady quality is reliable, the operation balance, and can realize the screening installation that secondary sieves.
The utility model is realized by following technical measures:
The utility model discloses the broken screening installation of a kind of anistree squirrel-cage, its main shaft is fixed on support by bearing arrangement, main shaft in horizontal direction, by the power section driven rotary; Being fixed with cross section on the main shaft is the octagonal anise sieve of being made by screen cloth; The outside of anistree sieve is equipped with the housing that does not rotate with main shaft, and lower part of frame has a discharging opening, and lower side has a waste material mouth, and upper side has a suction port; In the internal fixation of anise sieve cross section being arranged is circular sieve nest, and mesh is welded by round steel on the sieve nest, and the screen distance on the sieve nest has welded guide pad greater than the aperture on the anise sieve on the sieve nest; At housing one side of waste material mouth is arranged, a waste outlet is arranged at the bottom of sieve nest; Opposite side at sieve nest has a charging aperture.
Sieve nest of the present utility model is welded by round steel and steel plate.Design has the spirally-guided blade in the sieve nest, makes sand lump be easy to pulverize and move.Anistree sieve is by screen cloth and band steel weldering system, leaves certain space with sieve nest, makes sand lump and anistree collision, friction carry out second-time breakage.
The using method of screening installation of the present utility model is: the sieve nest that the old sand agglomerate is entered into rotation by charging aperture, sieve nest with rotation rises, throws down, carry out primary fragmentation, old sand behind crushing and screening enters into the anistree sieve of the second layer, carry out second-time breakage, thereby realized an equipment secondary effect of sieving with anise collision, friction.Sieve out sand and foreign material, sand enters circulatory system repeat function, and foreign material are discharged by the waste material mouth.
This equipment is used for the old sand of continuous crushing, screening foundry, has improved the recovery utilization rate of old sand greatly, has that steady quality is reliable, the operation balance, and can realize the advantage that secondary sieves.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
Wherein: 1, power section 2, waste material mouth 3, main shaft 4, suction port 5, housing 6 anistree sieves 7, sieve nest 8, guide pad 9, charging aperture
(5) specific embodiment
Accompanying drawing has provided structural representation of the present utility model.The screening installation of present embodiment, its power section 1 comprise deceleration device and configuration motor.Main shaft 3 is fixed on support by bearing arrangement, and main shaft is rotated by driven by motor in horizontal direction.Being fixed with cross section on the main shaft is the octagonal anise sieve of being made by screen cloth 6, and anistree sieve is by screen cloth and band steel weldering system.The outside of anistree sieve is equipped with the housing 5 that does not rotate with main shaft, and lower part of frame has a discharging opening, and lower side has a waste material mouth 2, and upper side has a suction port 4.In the internal fixation of anise sieve cross section being arranged is circular sieve nest 7, and sieve nest is welded by round steel and steel plate, is welded with five row's helical form guide vanes 8 in the sieve nest, and the aperture on the sieve nest is greater than the aperture on the anise sieve.At housing one side of waste material mouth 2 is arranged, a waste outlet is arranged at the bottom of sieve nest; Opposite side at sieve nest has a charging aperture 9.
Claims (1)
1. broken screening installation of anistree squirrel-cage, main shaft (3) is fixed on support by bearing arrangement, main shaft in horizontal direction, by power section (1) driven rotary; Being fixed with cross section on the main shaft is the octagonal anise sieve of being made by screen cloth (6); The outside of anistree sieve is equipped with the housing (5) that does not rotate with main shaft, and lower part of frame has a discharging opening, and lower side has a waste material mouth (2), and upper side has a suction port (4); It is characterized in that: in the internal fixation of anise sieve cross section being arranged is circular sieve nest (7), and mesh is welded by round steel on the sieve nest, and the screen distance on the sieve nest has welded guide pad (8) greater than the aperture on the anise sieve on the sieve nest; At housing one side of waste material mouth (2) is arranged, a waste outlet is arranged at the bottom of sieve nest; Opposite side at sieve nest has a charging aperture (9).
