Abstract

The invention discloses a structure-improved drawplate on a bar-type sludge extruder. The drawplate comprises a plate body of the drawplate, wherein a concave platform is formed in the upper end surface of the plate body, a plurality of discharging holes penetrating through the lower end surface of the plate body are formed in the bottom surface of the concave platform, a plurality of stepped holes are formed in the lower end surface of the side edges of the plate body, a sink platform is formed in the lower end surface of the plate body, a mold plate is inserted and connected in the sink platform, a plurality of through holes opposite to the discharging holes are formed in the mold plate, the diameter of the through holes is smaller than that of the discharging holes, pins are inserted and connected in the stepped holes of the plate body, first studs are formed on upper end surfaces of the pins, upper ends of the first studs are exposed to the upper end surface of the plate body, second studs are formed on lower end surfaces of the pins, the second studs are sleeved with press blocks, one end of each press block is pressed against the mold plate, and nuts are pressed against the press blocks and connected onto the second studs in a screwed manner. The drawplate can mold two kinds of bar-type sludge with different thickness, all that is required is to replace the corresponding mold plate instead of replacing the whole drawplate, and the labor intensity is reduced.

Description

Structure improved draw ring on a kind of mud bar shaped extruding machine

Technical field:

The present invention relates to the technical field of mud bar shaped extruding machine, more specifically to structure improved draw ring on a kind of mud bar shaped extruding machine.

Background technology:

Mud extruding machine, it is the equipment in dirt purified treatment, it is and mud is extruded the equipment taken various shapes, and bar shaped extruding machine, namely it is the equipment that mud is squeezed out molding strip, solid accumulation can be made highly consistent by mud extruding being had a bar shape, increase voidage, increase the contact area of mud and hot-air, reduce hot-air penetrate mummification with time flow resistance, mummification efficiency can be effectively improved. The operation principle of existing mud extruding machine is by rotating extruding machine inner cross head, change volume, thus mud being extruded into from the discharge opening of draw ring bar shaped, the thickness of bar shaped mud is determined by the aperture of draw ring discharge opening, different humidity, type mud in order to make mummification best results, it is desirable to the bar shaped mud of extrusion different thicknesses, the bar shaped mud of different thicknesses requires to change different draw ring, and draw ring is comparatively heavy, changes and comparatively bother.

Summary of the invention:

The purpose of the present invention is aiming at the deficiency of prior art, and provide structure improved draw ring on a kind of mud bar shaped extruding machine, and the bar shaped mud of its draw ring two kinds of different thicknesses of energy molding, then only need to change corresponding template, without changing whole draw ring, reduce labor intensity.

Structure improved draw ring on a kind of mud bar shaped extruding machine, plate body including draw ring, the upper surface of plate body forms concave station, the bottom surface of concave station forms several discharge openings running through plate body lower surface, the lower surface of plate body side forms some stepped holes, the lower surface of plate body forms heavy stand, template it is plugged with in heavy stand, template forms several through holes relative with discharge opening, the diameter of through hole is less than the diameter of discharge opening, it is plugged with pin in the stepped hole of described plate body, the upper surface of pin forms the first stud, the upper end of the first stud is exposed on the upper surface of plate body, the lower surface of pin forms the second stud, second stud upper sleeve has briquetting, one end of briquetting is pressed against in template, described briquetting has been pressed against nut, nut is screwed onto on the second stud.

Forming positioning frame on the upper surface of the plate body of described concave station surrounding, positioning frame upper sleeve has seal washer.

Described through hole and discharge opening are respectively uniformly distributed in template and plate body, and the seamed edge of plate body lower surface forms chamfering.

Two outer walls that described second stud lower end is relative form parallel grooving.

The beneficial effects of the present invention is:

Draw ring is improved by it, the template in differently configured aperture in draw ring, it is achieved draw ring can distinguish the bar shaped mud of two kinds of different-diameters of molding by regulating, and when requiring the bar shaped mud of different-diameter, as long as changing template, changes more convenient simultaneously.

Accompanying drawing illustrates:

Fig. 1 is the structural representation that invention is three-dimensional;

Fig. 2 is the perspective view inventing another angle;

Fig. 3 invents the perspective view without template.

In figure: 1, plate body; 11, concave station; 111, discharge opening; 12, chamfering; 13, stepped hole; 14, positioning frame; 15, heavy stand; 2, pin; 21, the first stud; 22, the first stud; 221, grooving; 3, seal washer; 4, template; 41, through hole; 5, briquetting 6, nut.

Detailed description of the invention:

Embodiment: see that Fig. 1 is to shown in 3, structure improved draw ring on a kind of mud bar shaped extruding machine, plate body 1 including draw ring, the upper surface of plate body 1 forms concave station 11, the bottom surface of concave station 11 forms several discharge openings 111 running through plate body 1 lower surface, the lower surface of plate body 1 side forms some stepped holes 13, the lower surface of plate body 1 forms heavy stand 15, template 4 it is plugged with in heavy stand 15, template 4 forms several through holes relative with discharge opening 111 41, the diameter of through hole 41 is less than the diameter of discharge opening 111, it is plugged with pin 2 in the stepped hole 13 of described plate body 1, the upper surface of pin 2 forms the first stud 21, the upper end of the first stud 21 is exposed on the upper surface of plate body 1, the lower surface of pin 2 forms the second stud 22, second stud 22 upper sleeve has briquetting 5, one end of briquetting 5 is pressed against in template 4, described briquetting 5 has been pressed against nut 6, nut 6 is screwed onto on the second stud 22.

Forming positioning frame 14 on the upper surface of the plate body 1 of described concave station 11 surrounding, positioning frame 14 upper sleeve has seal washer 3.

Described through hole 41 and discharge opening 111 are respectively uniformly distributed in template 4 and plate body 1, and the seamed edge of plate body 1 lower surface forms chamfering 12.

Two outer walls that described second stud 22 lower end is relative form parallel grooving 221.

Operation principle: the present invention is the draw ring of mud bar shaped extruding machine, it installs the template 4 of different pore size on the plate body 1 of draw ring, during form removal 4,, in the bar shaped mud forming a kind of aperture, during installation form 4, can there is again the bar shaped mud in another aperture in its draw ring, as long as so configuring the template 4 of multiple different pore size, just can meet the molding demand of the mud of different humidity, type, change template 4 and compare the whole draw ring of replacing, conveniently many.
