Abstract
The utility model discloses an extruding barrel for use in a vacuum pug mill. The extruding barrel is arranged on a pug discharge barrel (2) of a vacuum pug mill (1), and comprises an expansion barrel (3), a straight barrel (4) and a contraction barrel (5), wherein one end of the expansion barrel is connected with the pug discharge barrel, and the other end of the expansion barrel is connected with one end of the straight barrel; the other end of the straight barrel is connected with one end of the contraction barrel; the other end of the contraction barrel is connected with a pug mill outlet (6); the length ratio of the contraction barrel to the expansion barrel is 1.5-2; and the tapers of the expansion barrel and the contraction barrel are 12-15 degrees. The extruding barrel of which the cross sectional area changes is arranged on the pug discharge barrel of the vacuum pug mill, and the moving direction of pug changes along with the increase of the cross sectional area in a pug milling process, so that the internal arrangement structure of pug tends to be more reasonable, molding and burning of pug are facilitated, the burning cost can be lowered, and the quality of ceramic products is improved.
Description
Technical field
The utility model relates to the annex on a kind of vacuum deairing machine, especially relates to the cylinder that extrudes that a kind of vacuum deairing machine that is conducive to improve the pugging quality uses.
Background technology
Vacuum deairing machine is the equipment of ceramic product manufacturing indispensability, not only is conducive to the ceramic material formed product by vacuum pugging, and can improve the quality of ceramic product.But existing vacuum deairing machine mostly has the following disadvantages in the pugging process: in ceramic material pugging process, because the cylinder of extruding on the vacuum deairing machine is direct compression-type, cause and extrude when extruding thicker product than too little, it is shorter to extrude the tube length degree, the pug internal structure is unreasonable, easily produce layering and helical form cracking, cause the ceramic product Quality Down.
The utility model content
For the problem that vacuum deairing machine in the above-mentioned prior art exists, the utility model provides a kind of and has been installed on the vacuum deairing machine sand pump, is conducive to reduce product and fires cost, and the vacuum pugging that improves the quality of products uses extrudes cylinder.
The technical scheme that the technical problems to be solved in the utility model is taked is: the described cylinder that extrudes is installed on the sand pump of vacuum deairing machine, it comprises expansion cylinder, straight tube and shrink cylinder, described expansion cylinder one end links to each other with sand pump, the other end links to each other with straight tube one end, the described straight tube other end links to each other with shrink cylinder one end, the shrink cylinder other end links to each other with the pug mill outlet, described shrink cylinder is 1.5-2 with enlarging the cylinder length ratio, described expansion cylinder and shrink cylinder tapering are the 12-15 degree, and described straight tube is that cylinder and length are 0.8-1.2 with an expansion length ratio.
The utility model is owing to be equipped with the cylinder that extrudes that cross-sectional area changes at the sand pump of vacuum deairing machine, pug changes owing to cross-sectional area increases in the pugging process, the pug direction of motion is changed, pug internal arrangement structure more is tending towards reasonable, be conducive to pug moulding, fire, can not only reduce and fire cost, and improve the quality of ceramic product.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
In the drawings, 1, vacuum deairing machine 2, sand pump 3, enlarge cylinder 4, straight tube 5, shrink cylinder 6, pug mill outlet.
The specific embodiment
In Fig. 1, the described cylinder that extrudes is installed on the sand pump 2 of vacuum deairing machine 1, it comprises expansion cylinder 3, straight tube 4 and shrink cylinder 5, described expansion cylinder one end links to each other with sand pump, the other end links to each other with straight tube one end, the described straight tube other end links to each other with shrink cylinder one end, and the shrink cylinder other end links to each other with pug mill outlet 6, and described shrink cylinder is 1.5-2 with enlarging the cylinder length ratio, described expansion cylinder and shrink cylinder are conical, and its tapering is the 12-15 degree; Described straight tube is cylindrical, and straight tube length is 0.8-1.2 with enlarging the cylinder length ratio.The concrete size that extrudes each part of cylinder in the present embodiment is: sand pump external diameter and expansion cylinder end diameter are 500mm, straight tube external diameter and shrink cylinder outside diameter are 700 mm, enlarging the tube length degree is 378mm, straight tube length is 350mm, shrink cylinder length is 650mm, enlarging a cylinder tapering is 14 degree, and the shrink cylinder tapering is 15 degree, enlarges cylinder, straight tube is identical with the shrink cylinder wall thickness.According to practical condition, extrude the concrete size of each part of cylinder and also can in the technological requirement scope of above-mentioned Length Ratio and tapering, adjust in addition.
Claims (1)
1. a vacuum deairing machine uses extrudes cylinder, it is installed on the sand pump (2) of vacuum deairing machine (1), it is characterized in that: the described cylinder that extrudes comprises expansion cylinder (3), straight tube (4) and shrink cylinder (5), described expansion cylinder one end links to each other with sand pump, the other end links to each other with straight tube one end, the described straight tube other end links to each other with shrink cylinder one end, the shrink cylinder other end links to each other with pug mill outlet (6), described shrink cylinder is 1.5-2 with enlarging the cylinder length ratio, and described expansion cylinder and shrink cylinder tapering are the 12-15 degree.
