Abstract

The invention discloses a rotary-unloading inlet/outlet anti-blockage structure which comprises a double-W anti-blockage structure at a feed opening of a housing and a W-shaped notch at a discharge opening of the housing, wherein the double-W anti-blockage structure comprises a notch and a W-shaped groove; the notch is parallel to the end surface of the feed opening and protrudes toward the center of the feed opening; the notch comprises a tooth mounted on the inner side surface of the feed opening and cutting edges located inside the feed opening and connected with two edges of the tooth; the tooth is shaped like a triangular pyramid; the bottom surface of the tooth is an isosceles right triangle and faces down; the outer edges of the cutting edges are straight lines; the W-shaped groove is located below the notch; the outline of the W-shaped groove is shaped like W, of which every two adjacent edges form a 90-degree angle; and the W-shaped notch comprises two parallel teeth with bottom surfaces facing down. According to the rotary-unloading inlet/outlet anti-blockage structure, the anti-blockage effect is realized by reducing the shear probability by changing the shape of the housing, the whole layout is reasonable, and the anti-blockage effect is remarkable.

Description

Anti-blockage structure is imported and exported in a kind of rotation discharging

Technical field

The invention belongs to the technical field of blockage prevention device, be specially one and rotate discharging import and export Anti-blockage structure.

Background technology

Rotating discharging is manner of execution common in solid material course of conveying, is mainly seen in the conveyings such as rotary discharger Equipment, when rotating discharging, often there is material cutting phenomenon in impeller and housing staggered place, if taking no action to, due to shearing Face is bigger, and the shearing force of generation is very big, and the equipment of frequently can lead to stops even damage of facilities accident.

At present, being primarily present two kinds of Anti-blockage forms in existing technology, a kind of is to be realized by additional mechanism, as Increasing elastic dialing flitch at material mouth, welding anti-sticking baffle plate, plug a funnel etc., this structure anti-sticking efficiency typically ratio is relatively low, Have also can be substantially reduced discharging efficiency, and causes equipment complicated, it is not easy to realize standardization；Another kind is by housing shape The change of shape reduces shearing probability, W type otch as outer in charging aperture W type, inside W groove, many serrated slot etc., and purpose is all to reduce to cut The probability cut, the number of teeth is more few better in theory, but due to the restriction of geometry, accomplish monodentate will affect integrally-built rationally Property, being typically chosen point of contact quantity is 2 points, up to three points, and have extends internally into some on the basis of 2, this knot Structure is more sensitive to material particular diameter and plasticity, mobility, runs into plasticity material good, poor fluidity and then easily blocks hopper and drop Low anti-sticking effect.

In prior art, the design of almost all of discharge valve discharging opening anti-sticking is performed practically no function even without just in case system is sent out Raw fault causes feed blocking at discharging opening, and the equipment that will immediately result in stops and even damages.

Content of the invention

It is an object of the invention to provide a kind of discharging import and export Anti-blockage structure that rotates, the physics of many-sided consideration material Characteristic so that equipment range of application is wider than traditional, is substantially reduced material material characteristic susceptibility, the anti-sticking being so designed that Position can be non-maintaining.

In order to solve above-mentioned technical problem, the technical solution used in the present invention is：

Anti-blockage structure is imported and exported in a kind of rotation discharging, including the double W Anti-blockage structure being positioned at housing charging aperture and position In the W type otch of housing discharge outlet, double W Anti-blockage structures include otch and W type groove, cuts parallel in charging aperture end face simultaneously And protrude to center of circle direction, otch includes the tooth being arranged on charging aperture medial surface, and tooth is triangular pyramid, and tooth bottom surface is Down, W type groove is positioned at suitable order, the profile w profile of W type groove for waist right angled triangle and bottom surface, adjacent two of W type groove While in 90 °, the W type otch being positioned at charging aperture is symmetrical arranged with the otch being positioned at discharging opening, and W type otch includes two teeth, Two teeth are arranged in parallel and bottom surface upward.

Further, double W Anti-blockage structures and W type otch are all and housing monoblock cast.

Further, W type groove left side edge is connected along charging aperture with right side edge.

The invention has the beneficial effects as follows：

The mode changing hull shape reduction shearing probability achieves the effect of anti-sticking, and integral layout is reasonable, anti-sticking effect Significantly, non-maintaining.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can be defined by the claims Implement with the multitude of different ways covering.

As shown in drawings, a kind of rotation discharging imports and exports Anti-blockage structure, including be positioned at the double W at housing 1 charging aperture N1 Anti-blockage structure and the W type otch 11 being positioned at housing discharging opening N2, double W Anti-blockage structures include otch 12 and W type groove 13, cut Mouth 12 is parallel to the end face of charging aperture N1 and protrudes to center of circle direction, and otch 12 includes being arranged on charging aperture N1 medial surface One tooth, tooth is triangular pyramid, tooth bottom surface be isosceles right triangle and bottom surface down, its sealing mechanism goes for institute Some plastic pellets and be unlikely to reduce discharging efficiency, and the tooth arranging for system material occur blocking when anti-sticking use, W Type groove 13 is positioned at below otch 12, the profile w profile of W type groove 13, and two adjacent limits of W type groove 13 are 90 °, set due to interior, The gravity of stock column own will be unlikely to shear staggered face at W type groove 13 and produce pressure, be positioned at the otch 12 of charging aperture N1 and be positioned at W type otch in discharging opening N2 is symmetrical arranged, and W type otch includes two teeth, two teeth are arranged in parallel and bottom surface upward, double W Anti-blockage structure and W type otch 11 are all and housing 1 monoblock cast.

In discharge process, material is entered by the charging aperture N1 of housing 1, and internal impeller 2 operate discharging in one direction, operates During material first pass around otch 12, bulk materials is chopped at two point of contacts along hypotenuse, piece material or plastic pellet Son continues to carry out anti-sticking shearing at W type groove 13, is chopped at two point of contacts along hypotenuse, when discharging opening N2 occurs putty accident When, W type otch 11 will have an effect, and material is sheared at three point of contacts along hypotenuse, and anti-sticking is imported and exported in the rotation discharging of the present invention Material structure, have employed the mode reducing shearing point, is reached the effect of anti-sticking by housing 1 shape, reduces equipment to material thing Reason characteristic susceptibility, it is adaptable to most granular materials, integral layout is reasonable, and anti-sticking effect is notable, and non-maintaining.

Invention described above embodiment, is not intended that limiting the scope of the present invention, any in the present invention Spirit and principle within modification, equivalent and the improvement etc. made, should be included in the claim protection model of the present invention Within enclosing.
