Description

Titanium dioxide washing pool

Technical Field

The utility model relates to a titanium white powder production field especially relates to a washing pond for titanium white washing.

Background

In the production process of titanium dioxide by a sulfuric acid method, water washing is one of key factors influencing the product yield and the product quality, and the aim of the water washing is to remove impurities in metatitanic acid, mainly iron. The requirements are that the washed metatitanic acid has good quality, the washing equipment has high efficiency, less water consumption and high recovery rate.

The leaf filter is widely used in the rinsing process of titanium dioxide powder water, comprises a frame and a filter plate, and is mainly used for separating filtrate and metatitanic acid slurry, and the separation process comprises the following steps: the leaf filter is lifted integrally by a travelling crane and placed in a water rinsing pool containing a mixture of metatitanic acid and water, filtrate is sucked out from a liquid outlet of the leaf filter by a vacuum system, slurry is adsorbed on a filter plate to form a filter cake, after the filtrate reaches a specified index, the vacuum system is closed, and the leaf filter is lifted to a discharge hopper by the travelling crane for discharging. The whole process needs to use a traveling crane to carry out cyclic operations of lifting, descending, re-lifting and the like, the leaf filter can swing left and right due to inertia in the descending process, so that the filter plate collides with the wall of the water rinsing pool, a glass fiber reinforced plastic anticorrosive layer of the wall of the water rinsing pool is damaged, metatitanic acid permeates into the wall from the anticorrosive layer, the water rinsing pool is corroded after a period of time, production stop repair is needed, and the filter plate is damaged by collision, so that the maintenance cost is increased; the top in the rinsing bath is equipped with the stopper, and is spacing for the leaf filter with the frame cooperation of leaf filter, and the stopper generally adopts steel preparation, and the leaf filter rocks about the decline in-process and rubs with the stopper, has destroyed the outer anticorrosive coating of leaf filter to accelerate leaf filter frame corrosion.

Chinese utility model patent publication No. CN214913936U discloses a leaf filter overhead hoist, include: top linear guide, the steering column that moves on top linear guide, the pull post hawser that the pulling steering column moved on linear guide, the loop wheel machine hawser of connecting the leaf filter, be provided with the bearing wheel on the steering column, the loop wheel machine hawser is walked around to the bearing wheel and turns to perpendicularly, the leaf filter includes: the device comprises an upper exhaust pipe, a vacuum pump, a water suction pump pipeline and a plurality of filter leaf mechanisms, wherein the filter leaf mechanisms are connected below the upper exhaust pipe, and the vacuum pump and the water suction pump pipeline are arranged on the upper exhaust pipe. This leaf filter overhead hoist can steadily carry the leaf filter to the dummy pit from the filtering ponds, nevertheless can't guarantee that handling in-process leaf filter can not take place to rock about.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that the cooperation mode of current leaf filter and rinsing bath can cause the anticorrosive coating of leaf filter or rinsing bath to be scraped and rubbed because rocking about the leaf filter, provides a titanium white rinsing bath for this reason.

The technical scheme of the utility model is that: the titanium dioxide washing tank comprises a tank body and a leaf filter positioned in the tank body, wherein vertical guide rails are arranged on the outer walls of two sides of the tank body, vertical guide rods are arranged on two sides of a rack of the leaf filter, pulleys are arranged at the bottom of the vertical guide rods, and the vertical guide rods are in sliding fit with the vertical guide rails through the pulleys.

In the scheme, the vertical guide rod is connected with a frame of the leaf filter in a welding manner.

In the scheme, the vertical guide rail is connected with the tank body through an embedded part.

In the scheme, the filter plate of the leaf filter is fixed with the frame by bolts.

In the scheme, a PO layer is lined outside the frame of the leaf filter.

In the scheme, the vertical guide rod and the vertical guide rail are made of carbon steel.

In the scheme, the filter plate of the leaf filter is made of polypropylene.

The beneficial effects of the utility model are that respectively newly-increased one set of pulley guide device at the head of leaf filter frame and afterbody for fixed leaf filter decline route ensures that leaf filter decline in-process filter plate does not collide the water rinsing pool wall, demolishs former stop device, guarantees that the outer anticorrosive coating of leaf filter frame is not destroyed.
