Abstract

An outer ring type vacuum extruder consists of an outer ring-shaped extruder body, a principal axis, a three-vane front wring knife head, a front mud cylinder in the shape of a port-protecting trumpet, an gas sealing sleeve gasket in a shape of orange petal arranged in the middle of a plaga knife, a cutting knife arranged on the sleeve of a rimer, an annular sandwich gas-gathering groove arranged in the peripheral of the middle of the machine body, an 'L'-shaped scraper, an air suction passage communicated with an upper gas-gathering box air suction system is arranged within 180 degrees in the upper part of the outer ring and a non-mud touched grate plate arranged in a feed port. The utility model has the advantages that: the pressure is added by 28 percent inside the machine head, the structure, volume and weight of a two-stage vacuum extruder are simplified, a machine price is reduced, the product quality and quantity are increased, saving electricity by more than 20 percent; the utility model can produce air-core bricks and solid bricks, is convenient to repair and maintain, and is adapted to the requirements of wall reformations.

Description

The external circular type de-airing extruder

The utility model relates to a kind of brick equipment, is the new architecture that adds four technological improvements on the spiral mud extruder of single shaft basis.

At present, the expensive technology difficulty of homemade two-stage vacuum agent mud machine power consumption high price; Most of brick fields are difficult to be accepted, and this is one of slow reason of wall improvement.The present utility model purpose is to provide a kind of low power consuming low price, improves extrusion pressure, can produce the external circular type vacuum agent mud machine that hollow brick can be produced solid brick again.

Technical solutions of the utility model are achieved in that the unique advantage of utilizing screw type, and outer shroud pneumatic trough position is peripheral at the body middle part, provide condition for shortening body length; The recycling useful space is characteristics of the present utility model.Only stay one to press the mud metal plate at receiving opening, adorn a grate plate of being made by the stainless steel square bar on the pressure mud metal plate position of cancellation, it can not be stained with mud by water-permeable and air permeable, backsight foam absorbent ventilate, and equal hole thin conduit is established in the upper end, and water usefulness gas all can reach the material mouth and not be stained with mud.

When material feeding section reamer pug being delivered to the middle part closed section compresses, extraneous air can not be got involved, make the thrust that tangerine flap garden shape spacer supports mudflow by the cross section cone, after the mud bar that is squeezed into the tangerine flap enters vacuum zone, be installed in reamer and put with four of main axis rotation oblique sword cutting knifes are cut into sheet, cutting knife is a scalene triangle.It is bigger to pick slice reamer pitch before cutting knife, it is slightly fast to pick speed, cause certain space, air is entered from the slice space in the outer shroud interlayer in one week, fall within the clod of inboard mouthful of interlayer, then have " L " type to be contained in scraper on the straight sword of the reamer starting point limit and extend in the interlayer and remove with main axis rotation.Utilize reamer to push away the mud rotation, its front air duct cross-sectional area behind is constant, ventilation characteristics up to head, in the 180 degree scopes of outer ring pneumatic trough top, degree of depth terminal point has three square breach to be cleaning, inspection passage, air stream very much not can take place for the body refuse phenomenon in the passage area, and institute's complete machine air of taking out is concentrated at pneumatic trough top plenum chamber, and the vavuum pump that is switched on is taken away.

Past, domestic paper conclusion was: long mud cylinder, coarse pitch, the slow-speed of revolution are to realize high efficiency key, see also the 9th page, 10 pages ZJ550A/500 two-stage vacuum mud extruders of 88 year third phase " brick and tile " magazine, it may be first representative type through strict arrangement of China.(one of data)

The utility model is thought: mud cylinder, reamer are long more, friction area is just big more, and power consumption is just many more, and pug is clipped in long big certainly apart from formed thrust in the middle of the reamer, and this short mud cylinder, short reamer can't be realized, have lacked and will return mud.Long mud cylinder and long reamer are to pug compression conveying, be more closely knit, but when having arrived head reamer head back, running into one to three group of resistance mud rod and reamer head is regardless of two of major-minor blade and founds swords and shred, to eliminate " S " type reamer line in the adobe, pug is to smear the motion of wiping state in the course of conveying in compression, have only to reconfigure behind the head of propelling and carry out static compression, for the last bonding compression horsepower ability of paying of pug density valuable.It is principal contradiction for a short time that the short head of mud cylinder returns mud pressure.Φ is antivacuum mud extruder below 400, and reamer outer under the receiving opening is routed to the reamer head, only adds a very narrow auxiliary-blade at the reamer head, play the counterweight effect, help to alleviate " disease of shaking the head ", to the base substrate compression compact, return mud and base substrate " S " line, it is very little to work.

Data shows, raw material soil shrinks slightly size, the mud extruder outlet is the same substantially, Φ 300 mud extruders and outlet pressure ratio are 2.4, Φ 500 brick machine ratios are up to 6.7, Φ 400 following mud extruder extruding forces are the main cause that product quality can not be up to standard for a short time, do not increase power and increase pressure, and be the utility model characteristics, present technique shortens body, and this part power is forwarded on the three blade conical reamer heads.(see also data two)

Three blade reamer heads old type increase by a leaf resistance, but its pushes area big 1/3rd and reach the head deutostoma is covered comprehensively, make to enter the head pug, and there do not have space and time to return to be excessive.

Enter bonding again static compression behind the head according to pug; The rule that the big product quality of head compression ratio is all right, the short mud cylinder of enlarging is better selection.It does not influence former type output and effectively improves the adobe packing.It is too big that enlarging (horn mouth) anterior slime tank should not expand, and for example Φ 400, and expansion is 450 to equal to increase by 1/8th, and pressure ratio increases by 28%.For making three blades all push work done, should leave breaking joint in the reamer at its rear side, need not refill resistance mud rod and destroy " S " line, three blade areas are impartial by 120 degree, and all more common major-minor blade of its chopping, covering, squeeze function reamer head increases more than 1/3rd.Three blade reamer front ends enter about the head sixth with head deutostoma tapering, top rake, and make enlarging volume and not enlarging of rear end volume it increase extruding force with shortening pitch to be directly proportional with efficient.Produce hollow brick and solid brick ratio, pitch is dwindled between 5 degree.Used core tool of hollow brick and machine mouth and other types are general.It is removable to sew on fan in the anterior slime tank level; Be convenient to change reamer and maintenance, lower fan and support one, good stability.
