The working principle is as follows:
taking the end cover out of the washing barrel to enable an opening at the upper end of the washing barrel to be exposed, injecting hydrolyzed metatitanic acid (water and titanium dioxide precipitates) into the washing barrel, enabling the solution to flow along the inner wall of the lower side of the washing barrel under the first filter plate, blocking titanium dioxide solids adsorbing a large amount of mother liquor above the first filter plate, putting the end cover back to the opening at the upper end of the washing barrel again at the moment, controlling water in the water storage tank to wash the titanium dioxide solids on the first filter plate, washing and removing impurities adsorbed on the titanium dioxide solids through clear water, and dropping below the first filter plate in the washing barrel along with water flow;
the control motor is started while water is drained into the washing barrel, the control motor drives the motor shaft to rotate in the washing barrel, the motor shaft drives the stirring plates to rotate in the washing barrel through the shaft sleeves when rotating, the rotating speed of the motor shaft is low initially, so that the centrifugal force applied to the extension plates in the extension plate grooves is small, the problem that the extension plates slide to the outside of the extension plate grooves through the first springs cannot be overcome, namely the extension plates cannot contact with the storage mechanism when the stirring mechanism operates, when the stirring plates rotate to the first filter plate, the stirring plates can push the first filter plate to slide in the four sliding grooves, the first filter plate is controlled to shake up and down in the four sliding grooves through the intermittent contact of the stirring plates and the first filter plate, the activity of titanium dioxide solids on the first filter plate is improved through the shaking of the first filter plate, the titanium dioxide solids are better contacted with water, and the washing of mother liquor by clear water is further improved, after the washing machine is washed for a certain time, stopping injecting water into the washing barrel by the water storage tank, driving the first filter plate to continuously shake in the four sliding chutes by the stirring mechanism, primarily drying moisture attached to the surface of the titanium dioxide solid by shaking of the first filter plate, closing the control motor after the moisture drying is finished, taking down the end cover from the upper end of the washing barrel again, and collecting pure titanium dioxide solid from the upper part of the first filter plate;
along with the proceeding of metatitanic acid water injection, the concentration component of sulfuric acid solution in the washing barrel is reduced, so that iron in the solution in the washing barrel is precipitated in a high-iron hydroxide form, at the moment, clear water in the water storage tank is changed into a bleaching agent, the end cover is placed above the washing barrel again, the control motor is started again to drive the stirring plates to rotate in the washing barrel, and the bleaching agent in the water storage tank is controlled to flow into the washing barrel, so that the acidity of the solution is improved, and the high-iron hydroxide which is precipitated is dissolved again;
when the control motor is started for the second time, the rotating speed of the motor shaft in the washing barrel is increased, namely the rotating speed of the stirring plate in the washing barrel is increased, the centrifugal force is increased, the extension plate slides to the outside of the extension plate groove under the action of the centrifugal force, the extension plate is driven by the stirring plate to be intermittently contacted with a first push plate, a butting block and a second push plate of the storage mechanism, when the extension plate is contacted with the first push plate, the first push plate drives the material pushing box to move downwards in the storage box a, the second spring stores force, after the extension plate is disconnected from the first push plate, the material pushing box is driven by the second spring to reciprocate in the storage box a, and calcium hydroxide emulsion in the storage box a is pushed into the washing barrel along the discharge valve a through the swinging of the material pushing box;
when the extension plate is contacted with the second push plate, the extension plate drives the push plate to move upwards in the storage box b by pushing the second push plate, a flocculating agent in the storage box b is counted into the washing barrel along the discharge valve b by the push plate, namely, the extension plate is intermittently contacted with the two storage mechanisms by the stirring mechanism, calcium hydroxide emulsion and the flocculating agent in the storage mechanisms are controlled to be intermittently and quantitatively squeezed into the washing barrel, iron in the solution is precipitated in a trivalent form again by the contact of the calcium hydroxide emulsion and a sulfuric acid solution, the sulfuric acid is precipitated in a calcium sulfate form to be a solid state to be precipitated in the washing barrel, and the flocculating agent in the washing barrel is added to condense the precipitate in the solution into suspended particles to float in the solution;
the intermittent discharge of the calcium hydroxide emulsion and the flocculating agent in the storage mechanism is controlled by the stirring mechanism, so that the emulsion and the flocculating agent are in higher contact reaction with the solution, the reaction among the emulsion, the flocculating agent and the solution is improved again by the rotation of the stirring mechanism, and meanwhile, the generated suspended particles are thrown to one side of the storage mechanism, which is far away from the central line of the washing barrel, under the driving of the stirring mechanism, namely the flocculated suspended particles fall on the second filter plate;
when the stirring mechanism operates, when the extension plate is contacted with the butt block, the extension plate extrudes the butt block to intermittently slide towards the butt block groove, the butt block slides in the process through the transmission of the pull rope, the second filter plate is controlled to shake up and down in the filter plate groove, the shaking of the second filter plate avoids flocculent particles from being pasted on the second filter plate on one hand, the filter holes on the second filter plate are blocked, the solution cannot perform circulating reaction in the water washing barrel, on the other hand, the shaking of the second filter plate can also convey flocculent suspended matters above the falling part to the storage box, the suspended particles fall above the third filter plate to be uniformly collected, the solution entering the storage box is conveyed back to the water washing barrel again under the control of the pump body to perform reaction, and the precipitation rate of impurities in the solution is further improved through the circulating reaction of the solution.

1. because rabbling mechanism's design, initially the rabbling mechanism speed is slower, and the rabbling mechanism can trigger the operating direction that filtering mechanism produced shake from top to bottom in the washtub, and when the speed of rabbling mechanism was very fast, the rabbling mechanism can trigger storage mechanism and intermittently extrude into in the washtub with calcium hydrate emulsion and flocculating agent and take place the reaction with solution, and the rotation of rabbling mechanism self can stir solution, emulsion and flocculating agent simultaneously, further improves three's reaction effect.
2. Due to the design of the filtering mechanism, the first filter plate is driven by the stirring mechanism to shake up and down in the four sliding grooves, the activity of titanium dioxide solids on the first filter plate is improved through the shaking of the first filter plate, the titanium dioxide solids are enabled to be better contacted with water, the washing of mother liquor by clear water is further improved, after the mother liquor is washed for a certain time, water is injected into the washing barrel from the water storage tank, the stirring mechanism drives the first filter plate to shake continuously in the four sliding grooves, the moisture attached to the surface of the titanium dioxide solids is primarily dried through the shaking of the first filter plate, the control motor is closed after the moisture drying is finished, the end cover is taken down from the upper end of the washing barrel again, and pure titanium dioxide solids are collected from the upper side of the first filter plate.

The working principle is as follows:
taking the end cover 102 out of the washing barrel 100 to expose an opening at the upper end of the washing barrel 100, injecting hydrolyzed metatitanic acid (water and titanium dioxide precipitate) into the washing barrel 100, enabling the solution to flow along the inner wall of the lower side of the washing barrel 100 under the first filter plate 106, blocking titanium dioxide solid adsorbing a large amount of mother liquor above the first filter plate 106, placing the end cover 102 back to the opening at the upper end of the washing barrel 100 again at the moment, controlling water in the water storage tank 130 to flush the titanium dioxide solid on the first filter plate 106, flushing impurities adsorbed on the titanium dioxide solid with clean water to remove, and dropping below the first filter plate 106 in the washing barrel 100 along with water flow;
the control motor 104 is started while water is drained into the washing barrel 100, the control motor 104 drives the motor shaft 108 to rotate in the washing barrel 100, the motor shaft 108 drives the plurality of stirring plates 110 to rotate in the washing barrel 100 through the shaft sleeve 109 when rotating, the rotation speed of the motor shaft 108 is slow initially, so that the centrifugal force applied to the extension plate 112 in the extension plate groove 111 is small, the extension plate 112 cannot slide to the outside of the extension plate groove 111 against a first spring, namely the extension plate 112 cannot contact with a storage mechanism when the stirring mechanism operates, when the stirring plate 110 rotates to the position of the first filter plate 106, the stirring plates 110 can push the first filter plate 106 to slide in the four sliding grooves 105, the first filter plate 106 is controlled to shake up and down in the four sliding grooves 105 through the intermittent contact of the plurality of stirring plates 110 and the first filter plate 106, the activity of titanium dioxide solids on the first filter plate 106 is improved through the shaking of the first filter plate 106, and the titanium dioxide solids are better contacted with water, the mother liquor is further flushed by clean water, after the mother liquor is cleaned for a certain period of time, water is stopped from being injected into the washing barrel 100 from the water storage tank 130, the stirring mechanism drives the first filter plate 106 to continuously shake in the four sliding grooves 105, moisture attached to the surface of the titanium dioxide solid is preliminarily dried through shaking of the first filter plate 106, the control motor 104 is closed after the drying of the moisture is finished, the end cover 102 is taken down from the upper end of the washing barrel 100 again, and pure titanium dioxide solid is collected from the upper side of the first filter plate 106;
along with the proceeding of metatitanic acid water injection, the concentration component of the sulfuric acid solution in the washing barrel 100 is reduced, so that iron in the solution in the washing barrel 100 is precipitated in a form of high-iron hydroxide, at the moment, clear water in the water storage tank 130 is changed into a bleaching agent, the end cover 102 is placed back to the upper side of the washing barrel 100 again, the control motor 104 is started again to drive the stirring plates 110 to rotate in the washing barrel 100, and the bleaching agent in the water storage tank 130 is controlled to flow into the washing barrel 100 to improve the acidity of the solution, so that the high-iron hydroxide which is precipitated is dissolved again;
when the control motor 104 is started for the second time, the rotation speed of the control motor shaft 108 in the washing tub 100 is increased, that is, the rotation speed of the stirring plate 110 in the washing tub 100 is increased, the centrifugal force is increased, the extension plate 112 slides to the outside of the extension plate groove 111 under the action of the centrifugal force, the extension plate 112 is driven by the stirring plate 110 to intermittently contact with a first push plate 116, an abutting block 120 and a second push plate 118 of the storage mechanism, when the extension plate 112 contacts with the first push plate 116, the first push plate 116 drives the material pushing box 114 to move downwards in the storage box 113a, the second spring is used for storing force, after the extension plate 112 is disconnected from the first push plate 116, the material pushing box 114 reciprocates in the storage box 113a under the action of the second spring, and the calcium hydroxide emulsion in the storage box 113a is pushed into the washing tub 100 along the material discharging valve 115a through the swinging of the material pushing box 114;
when the extension plate 112 contacts the second push plate 118, the extension plate 112 drives the push plate 117 to move upwards in the storage tank 113b by pushing the second push plate 118, the flocculant in the storage tank 113b is counted into the washing tank 100 along the discharge valve 115b by the push plate 117, that is, the extension plate 112 intermittently contacts with the two storage mechanisms by the stirring mechanism, the calcium hydroxide emulsion and the flocculant in the storage mechanisms are controlled to intermittently and quantitatively squeeze into the washing tank 100, iron in the solution is precipitated in a trivalent form again by the contact of the calcium hydroxide emulsion and the sulfuric acid solution, the sulfuric acid is precipitated in a calcium sulfate form to be a solid state to be precipitated in the washing tank 100, and the flocculant in the washing tank 100 is added to flocculate the precipitate in the solution into suspended particles to float in the solution;
the intermittent discharge of the calcium hydroxide emulsion and the flocculating agent in the storage mechanism is controlled by the stirring mechanism, so that the emulsion and the flocculating agent are in higher contact reaction with the solution, the reaction among the emulsion, the flocculating agent and the solution is improved again by the rotation of the stirring mechanism, and meanwhile, the generated suspended particles are thrown to one side of the storage mechanism far away from the central line of the water washing barrel 100 under the driving of the stirring mechanism, namely, the flocculated suspended particles fall on the second filter plate 123;
when the stirring mechanism is operated and the extension plate 112 is contacted with the abutting block 120, the extension plate 112 presses the abutting block 120 to intermittently slide into the abutting block groove 119, the second filter plate 123 is controlled to shake up and down in the filter plate groove 122 through the transmission of the pull rope in the sliding process of the abutting block 120, on one hand, the shaking of the second filter plate 123 prevents the flocculated particles from being attached to the second filter plate 123, which causes the filter holes on the second filter plate 123 to be blocked, the solution can not be circularly reacted in the washing tank 100, on the other hand, the shaking of the second filter plate 123 can also convey the flocculated suspended matters falling from the upper part into the storage tank 124, so that the suspended particles fall on the third filter plate 126 for uniform collection, meanwhile, the solution entering the storage tank 124 is conveyed back to the water washing barrel 100 again to react under the control of the pump 129 along the guide pipe 128, and the precipitation rate of impurities in the solution is further improved through the circulation reaction of the solution.
