Abstract

A screw-type washer with a 'build-in bearing seat built in the tail part' provides a sand-proof and water-proof screw-type washer, which reconstructs tail bearing seats of the prior arts and arranges the whole tail bearing seat in a screw-spindle barrel. The screw-type washer is capable of protecting the tail bearing seat away from of sand and water, guaranteeing the bearing seat not being damaged during operation, thereby reducing the idling time for maintenances and improving the productive efficiency of the screw-type washer.

Description

Screw sand washer with " the built-in built-in bearing block of afterbody "

Affiliated technical field

The utility model relates to the used screw sand washer of a kind of building material industry.

Background technology

The domestic and international at present screw sand washer of producing, its tail bearing seat all is to adopt afterbody hoisting type or external bearing block.Because the afterbody of screw sand washer is to be in to mix in the water to work, and just makes to have the situation that the tail bearing seat leaks often and advances sand now, often makes the main shaft of screw sand washer produce the seize fault.This class fault has had a strong impact on carrying out smoothly of producing, and usually allows whole flow production line stop and keeps in repair, and causes bigger economic loss.The version of therefore existing screw sand washer tail bearing seat is one urgently technical problem to be solved.

Summary of the invention

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of its tail bearing seat can be every the sand waterproof, guarantee that rear bearing can not be damaged, and can significantly reduce the maintenance off-time, the screw sand washer of enhancing productivity when work.

The purpose of this utility model is to reach by following technical measures: it is that the rear end axle in the screw sand washer rear end bearing holder assembly is fixed by anchor ear, and on the axle of rear end, be equipped with forward and backward two the dish bearings, its rear end bearing block shape is the cylinder that afterbody has ring flange, and forward and backward two dish bearings are installed in the cylinder of this bearing block.The front end of rear end bearing seat is sealed up by the water shutoff lid, and the rear end of rear end bearing seat is sealed up by the water shutoff seat that has J type oil sealing.Whole rear end bearing holder assembly is to be sleeved in the spiral central siphon of screw sand washer, and is fixed together by ring flange on the rear end bearing seat and spiral central siphon.

The utility model advantage compared to existing technology is: the rear bearing block of this screw sand washer can be effectively every sand, and waterproof has thoroughly solved the technical barrier that advances the sand water inlet and damage bearing.So just ensured complete machine stability, reduced the off-time, improved production efficiency, prolonged the service life of this machine.

Description of drawings

Fig. 1 is the structure chart of the utility model screw sand washer.

Fig. 2 is the structure chart of rear end bearing holder assembly.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples: this screw sand washer is on the basis that has traditional screw sand washer now, the rear end bearing seat of conventional helical sand washer is transformed form.It is that shaped design with rear end bearing seat 1-4 becomes afterbody to have the cylinder of ring flange, and with two dish bearing 1-2, and 1-5 is before one, one afterwards be installed in the cylinder.Two dish bearing 1-2, the rear end axle 1-3 that 1-5 supported is placed on the inner ring of this two dishes bearing.Rear end axle 1-3 is positioned at the anchor ear 2 of its afterbody again to be fixed.The front end face of rear end bearing seat 1-4 is sealed up by water shutoff lid 1-1 again simultaneously; And rear end face is sealed by the water shutoff seat 1-6 that has J type oil sealing 1-7.And whole rear end bearing holder assembly 1 must be sleeved in the spiral central siphon 3 of screw sand washer, but also will be fixed together by ring flange on the rear end bearing seat 1-4 and spiral central siphon 3.During this screw sand washer work, its whole rear end bearing holder assembly can be by sand and water enchroachment (invasion) evil just by in the interior plant helical axis pipe.
