Description

Sand mill

Technical Field

The utility model relates to a grinding device technical field especially relates to a sand mill.

Background

The bottom plate feed hole and the drain hole of the prior sand mill are directly connected with the bottom plate through short joints, the feed hole is used for feeding raw materials, and the drain hole is used for draining beads in the sand mill. In the using process, the liquid corrosion in the sand mill causes the sealing performance of the feed hole and the drain hole to be reduced, so that the liquid seeps out, crystals are formed, the field '5S' management is influenced, and certain potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the shortcoming and not enough among the prior art, provide a sand mill.

The utility model discloses a realize through following technical scheme: a sand mill comprises a sand mill body and a bottom plate arranged below the sand mill body; the bottom plate is provided with a feed hole and a discharge hole, and the device also comprises

A feed tube, a portion of the feed tube being inserted into the feed aperture; and

a drainpipe, a portion of which is inserted into the drainhole.

Compared with the prior art, the feeding pipe and the discharging pipe are independently inserted into the bottom plate of the sand mill, so that liquid is prevented from corroding the feeding port and the discharging port of the bottom plate and seeping out crystals, and the service life of the equipment is prolonged; the field working environment is improved, and the safety and environmental protection risks are reduced.

Further, the feeding pipe and the discharging pipe are connected with the bottom plate in a full welding mode.

The feed pipe and the tapping pipe are secured by welding under said floor.

Further, the feeding hole is a stepped hole; the major diameter of the stepped hole is the same as the outer diameter of the feeding pipe; the small diameter of the stepped hole is the same as the inner diameter of the feeding pipe.

Through setting the feed port to with the shoulder hole that the inlet pipe corresponds, make liquid pass through the in-process of inlet pipe avoids contacting with the welding seam, avoids the welding seam to receive the corruption.

Further, the bleeder is a stepped hole; the major diameter of the stepped hole is the same as the outer diameter of the drainpipe; the small diameter of the stepped hole is the same as the inner diameter of the drainpipe.

By arranging the drain hole as a stepped hole corresponding to the drain pipe, liquid is prevented from contacting the weld joint during the process of passing through the drain pipe, and the weld joint is prevented from being corroded.

Further, the device also comprises a feeding valve and a discharging valve; the lower end of the feeding pipe is provided with a flange corresponding to the feeding valve; the lower end of the drainpipe is provided with a flange corresponding to the drain valve.

Through setting up feed valve, drainage valve and the flange that corresponds respectively, make things convenient for the dismouting maintenance.

Further, the flange at the lower end of the feeding pipe and the flange at the lower end of the discharging pipe are convex flanges.

By providing a raised flange, the likelihood of liquid penetration may be reduced.

Furthermore, a tetrafluoro gasket is arranged between the flange at the lower end of the feeding pipe and the feeding valve.

Furthermore, a tetrafluoro gasket is arranged between the flange at the lower end of the discharge pipe and the discharge valve.

The possibility of liquid penetration is further reduced by adding a tetrafluoro gasket.

Further, the feeding pipe and the discharging pipe are both made of acid-resistant and wear-resistant stainless steel.

By using the acid-resistant and wear-resistant stainless steel, the abrasion and corrosion of the pipeline are reduced.
