Abstract
An anti-blocking mixed-material self-flowing and screening device comprises a rear cross plate, a rear support rod, a front cross plate, a front support rod and longitudinal screening bars. The anti-blocking mixed-material self-flowing and screening device is characterized in that the longitudinal screening bars are T-shaped bar steel with T-shaped sections, and upper cross plates on the T-shaped bar steel are arranged in a manner of being wider in the rear and narrower in the front. The anti-blocking mixed-material self-flowing and screening device has the advantages that particles among the T-shaped bar steel are high in sliding speed and less in blocking.
Description
technical field:
The utility model relates to screening plant, particularly a kind of anticlogging batch mixing Automatic-flow screen separating device.
background technology:
In production process, often need to carry out screening and the conveying of batch mixing, for the granular material in batch mixing, granular material or lump material (being conventionally referred to as it with the material within the scope of certain size), as the coal of one of Chemical Manufacture raw material in good time.Batch mixing after exploitation need to sieve and split processing by its particle diameter difference.Although how irregular its shape is, the pellet that lump material is larger or strip or partially shape or irregular toroidal, granule material mostly is toroidal.Conventional practice is to utilize the mobility of batch mixing, with slide sieve method, sieve, at a certain distance, along the batch mixing direction of motion, low early and high after (guaranteeing certain mounted angle), the several round steel slide sieve of parallel laid bar are made one group of sieve, rely on that the movement velocity of potential energy difference and batch mixing is poor completes screening.In use, due to the rubbing action between batch mixing and grating, part batch mixing usually jam, among grating gap, causes blanking to stop up, and traditional approach is often unsatisfactory.
The screening plant that tradition slide sieve method is used is comprised of rear transverse slat, back stay, front transverse slat, front support rod, longitudinal grating.Front and back pole is supported respectively low early and high after front and back transverse slat, and transverse slat equal intervals is welded and fixed some gratings, and this grating is all round bar.Grating inclination angle is generally 20-35 degree angle.
The defect of this structure is: with the easy blocking in two round bars of the substantially isometrical or bigger particle of two round bar spacing.How in other words tracing it to its cause one is big up and small down horn-like in cross section, space between two round bars, with the contact-making surface great Yi screens of the contact point position of particle; Next is that two round bars are equidistant, and particle is easy to upper just blocking, because upper potential energy difference is little, kinetic energy values is also little, stop too early material and slip row, also wants longitudinal comprehensive block clearing during cleaning, and workload is large.
summary of the invention:
The purpose of this utility model is to overcome above-mentioned defect, and a kind of anticlogging batch mixing Automatic-flow screen separating device is provided.
Scheme of the present utility model is: comprise rear transverse slat, back stay, front transverse slat, front support rod, longitudinal grating, it is characterized in that: longitudinally grating is the T shape bar steel of the T-shaped shape in cross section, and T shape bar steel upper lateral plate is rear wide front narrow shape.
The utility model has the advantage of: particle slippery speed between T shape bar steel is fast, and blocking is few.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 2.
the specific embodiment:
The utility model comprises rear transverse slat 1, back stay 4, front transverse slat 3, front support rod 5, longitudinal grating, it is characterized in that: longitudinally grating is the T shape bar steel 2 of the T-shaped shape in cross section, and T shape bar steel 2 upper lateral plates are rear wide front narrow shape.
Little large after spacing due to two T shape bar steel 2, thus when substantially isometrical or bigger particle is slippery because posterior segment spacing is little, and these grain diameters are more much bigger than back segment, stage casing, so a sliding and mistake, speed is fast, efficiency is high.Slippery when the leading portion latter end, the just upper corner angle of both sides T shape bar steel 2 of contact with it, contact-making surface is than much smaller with round bar, now inertia force is also large, fast by otherwise hurtle down, blocking not substantially.If blocking can be in the screens of grating total length yet, only meeting is in the indivedual blockings of leading section, and block clearing is also fast.
