Abstract

The utility model relates to an adjustable spiral apparatus for separating sand from water without a shaft, which can separate particles having large specific gravity such as sand stone, cinder, etc. from sewerage. The utility model is composed of a water inlet pipe, a drain pipe, a water tank, a U-shaped slot, a spiral with a shaft and a reduction box. The spiral without a shaft is positioned in the U-shaped slot, and the front end of the spiral without a shaft is connected with the reduction box via a shaft journal and driven by the reduction box. The spiral without a shaft is contacted with a plurality of furring strips fixed to the U-shaped slot, and the front end of the U-shaped slot is provided with a sand outlet. The utility model is characterized in that the outer end of the shaft journal is provided with screw threads matched with regulating nuts and locking nuts in order to form an axial clearance adjustment pair for the operation of the spiral without a shaft.

Description

Can regulate no axial spiral type grit water separator

The utility model relates to a kind of sewage disposal special equipment, the no axial spiral type grit water separator that particle separation such as particularly a kind of sand, stone, cinder that can proportion in the sewage is bigger is come out.

Existing no axial spiral type grit water separator is by inlet pipe, drain pipe, there is not the axle spiral, U type groove, water tank and reduction box are formed, during its work, sand water mixed liquid from setting pot is imported water tank from separator one end top, what proportion was bigger in the mixed liquor will be deposited on U type trench bottom as sand grains etc., under the promotion of not having the axle spiral, sand grains is raised along tilting U type bottom land, continue to be pushed a segment distance after leaving liquid level, fully dewater after sand removing hole unloads to containing sand launder, then drain into cesspool in the factory from overfall with water after sand grains separates at sand grains.But this no axial spiral type sandstone separator can extend axially because of fatigue produces nothing axle spiral after operation a period of time, cause the safe operation gap of its tail end and water tank end face to reduce even can rub, therefore prescind one section spiral and could guarantee normally to move time-consuming effort not having to pull down after axle extends spirally.

The purpose of this utility model is exactly in order to address the above problem, and a kind of conveniently adjusted regulated nothing axial spiral type grit water separator that does not have the axle helix length is provided.

Technical solution of the present utility model:

A kind ofly regulate no axial spiral type grit water separator, it is still by inlet pipe, drain pipe 1,5, water tank 2, U type groove 6, there are not axle spiral 4 and reduction box 3 compositions, do not have axle spiral 4 and be positioned at U type groove 6, its front end links to each other with reduction box 3 by axle journal 7, and by reduction box 3 drivings, do not have axle spiral 4 and contact with multiple tracks lead-in on being fixed on U type groove 6, the front end of U type groove 6 has sand removing hole 8, it is characterized in that being provided with screw thread in the outer end of described axle journal 7, connected on it and adjusted nut 9 and locking nut 10, constituted the axial clearance regulation of not having 4 operations of axle spiral and pay.

The utility model is set up screw thread first and is paid structure on nothing axle spiral, to be used for regulating the active length of not having the axle spiral, guarantee the safe handling gap of nothing axle spiral tail end and water tank end face.The utility model is simple in structure, and is easy to adjust, need not to pull down also to need not cutting, and saving of work and time is laborsaving, and effect is very good.

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is a plane of the present utility model section structure schematic diagram.

As Fig. 1,2, the utility model did not have axle spiral 4 and is subjected to fatigue to influence the meeting axial elongation, so that the end face of friction water tank 2 after operation a period of time.This moment, the releasable lock jack panel 10, regulate and adjust nut 9, the extension of not having axle spiral 4 is accessed, and then locking locking nut 10, so just can guarantee that the tail end of nothing axle spiral 4 and the security of operation gap a between water tank 2 end faces meet the requirements all the time, can not rub.

Claims

1, a kind ofly regulate no axial spiral type grit water separator, it is still by advancing, drainpipe (1), (5), water tank (2), U type groove (6), not having axle spiral (4) and reduction box (3) forms, do not have axle spiral (4) and be positioned at U type groove (6), its front end links to each other with reduction box (3) by axle journal (7), and drive by reduction box (3), do not have axle spiral (4) and contact with multiple tracks lead-in on being fixed on U type groove (6), the front end of U type groove (6) has sand removing hole (8), it is characterized in that being provided with screw thread in the outer end of described axle journal (7), connected adjustment nut (9) and locking nut (10) on it, constituted the axial clearance regulation of not having axle spiral (4) operation and pay.
