Description

Delay equipment of black double screw barrel inside lining wearing and tearing for master batch

Technical Field

The utility model relates to a master batch processing production technical field specifically is a delay equipment of black master batch with double screw barrel inside lining wearing and tearing.

Background

The barrel is one of two major operating parts of the double-screw extruder, the other is a screw, only the barrel and the screw form a pair of friction groups, no matter whether the auxiliary agent is in a solid state in a feeding area, the filament limitation of a glass fiber area, the high-speed operation of the screw in a middle area or the screw in a cantilever state in a rod head area, the friction and the scratch are caused to the inner wall of the barrel, and the abrasion of the inner wall of the barrel is caused. The existing solution scheme is that the cylinder body is frequently replaced only in a heavy wear area, even if the lining is arranged, most of the lining is of an integral structure, once the lining is worn, the whole lining needs to be replaced, so that the production progress of an enterprise is influenced, the production cost is increased, and the consumption is huge.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a following technical scheme: a device for delaying abrasion of a double-screw cylinder liner for black master batches comprises a double-screw cylinder; the double-screw barrel is characterized by also comprising a lining, wherein the lining is tightly attached to the inner wall of the double-screw barrel and is formed by combining a plurality of same splicing blocks; the double-screw cylinder is characterized by further comprising a V-shaped connecting block, wherein the V-shaped connecting block is fixed at the concave position of the double-screw cylinder body.

Preferably, the splicing block comprises a first cylindrical surface, a second cylindrical surface, an upper connecting surface and a lower connecting surface.

Preferably, the first cylindrical surface and the second cylindrical surface are two arc surfaces with the same radian and are cut from a group of concentric circles.

Preferably, the upper engagement surface is an arc-shaped cross section formed by cutting half of the first cylindrical surface, and the lower engagement surface is an arc-shaped cross section formed by cutting half of the second cylindrical surface.

Preferably, the V-shaped connecting block and the splicing block are fixed through bolts.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model divides the whole lining into a plurality of splicing blocks with the same size, thereby facilitating the installation and the disassembly of the lining, and only one splicing block needs to be replaced even if the lining is divided into different areas, thereby greatly saving the cost; meanwhile, according to the special shape of the splicing block, a large number of bolts required to be consumed during installation are reduced, and the operation of workers is facilitated.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, an apparatus for delaying wear of a liner of a twin-screw cylinder for black masterbatch comprises a twin-screw cylinder 1; the double-screw barrel comprises a double-screw barrel body 1, and is characterized by also comprising a lining 2, wherein the lining 2 is tightly attached to the inner wall of the double-screw barrel body 1 and is formed by combining a plurality of same splicing blocks 3; the double-screw barrel is characterized by further comprising a V-shaped connecting block 4, the V-shaped connecting block 4 is fixed at a concave position of the double-screw barrel body 1, and the V-shaped connecting block 4 and the splicing blocks 3 are fixed through bolts 9.

The splice 3 includes a first cylindrical surface 5, a second cylindrical surface 6, an upper engagement surface 7, and a lower engagement surface 8. The first cylindrical surface 5 and the second cylindrical surface 6 are two arc surfaces with the same radian and are cut out from a group of concentric circles. The upper engagement surface 7 is an arc-shaped cross section formed by cutting half of the first cylindrical surface 5, and the lower engagement surface 8 is an arc-shaped cross section formed by cutting half of the second cylindrical surface 6.

In summary, according to the requirement of extruding the auxiliary agent, the material of the liner 2 can be selected as an alloy material, and the outer surface thereof, i.e. the first cylindrical surface 5 of each splicing block 3 is the surface contacting with the cylinder, the second cylindrical surface 6 is the surface contacting with the screw and the auxiliary agent, and the upper connecting surface 7 and the lower connecting surface 8 are just matched. Therefore, the splicing blocks 3 are connected end to form a complete circular ring. However, the utility model discloses a double screw barrel is crossed by two circles and forms, consequently is provided with the V type connecting block 4 that agrees with mutually with the depressed part in the depressed part as being connected of originated department and end splice block, and two upper and lower V type connecting blocks 4 are all fixed mutually with splice block 3 through the bolt. According to the different stress points of the shapes of the splicing blocks 3, the splicing blocks 3 attached to the circular arc part of the cylinder body can be kept stable and not affected, and the reinforcing by using bolts is not needed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
