Description

TECHNICAL FIELD

[0001] The present application relates to the field of belt filter press, and particularly relates to a belt filter press for wastewater treatment in zirconium titanate production. BACKGROUND

[0002] The belt filter press is a very practical and efficient sludge dewatering equipment, which separates solid and liquid in sludge through mechanical extrusion dewatering, and the solid impurities are extruded into cakes after the liquid is squeezed out, so that the solid impurities can be collected and treated conveniently.

[0003] In the production process of zirconium titanate, wet beneficiation treatment is needed, and after the beneficiation treatment is completed, concentrate dewatering treatment is needed, that is, the mixture of concentrate and water is separated by the belt filter press, and the water in the concentrate is squeezed out, so that the blocky or cake-shaped concentrate can be obtained, thereby facilitating the collection of the concentrate by the staff, and the filter belt has a certain elastic deformation capacity and can tightly wrap the solid sludge like a "bandage", so that the water is squeezed out under extrusion.

[0004] When the solid-liquid mixture of concentrate is arranged above the filter belt, in order to make the two filter belts extruding each other can fully squeeze out the water in the solid-liquid mixture of concentrate, the solid-liquid mixture can be uniformly distributed on the filter belt by the distribution structure, and the two filter belts can extrude the uniformly distributed solid-liquid mixture as the filter belt is driven, but the existing distribution structure is only through multiple groups of prongs arranged in parallel and staggered to treat the solid-liquid mixture multiple times, but this way cannot achieve effective uniform distribution, and the possibility of solid agglomeration in the solid-liquid mixture is not considered, when the solid components in the solid-liquid mixture are not uniformly distributed into the two filter belts for extrusion dewatering, the position where the solid components are accumulated is prone to bulge between the two filter belts, and the two filter belts are elastically pressed together by two pressure rollers, when the position between the two filter belts is bulged, the position where the solid components are accumulated cannot be effectively extruded and dewatered, thereby reducing the dewatering effect of the solid-liquid mixture.

When the straight bar 26 with a plurality of clamping rings 35 reciprocates, the clamping ring 35 can frequently move the outer wall of the first filter belt 4 and the second filter belt 5 woven into the first filter belt 4 and the second filter belt 5, which further improves the separation effect of zirconium titanate solid particles. Working principle: during the transportation of the solid-liquid mixture of zirconium titanate into the limiting sleeve 12, the two rollers 13 are moved synchronously and reversely in the limiting sleeve 12 by the second motor 14, which can disperse the agglomerated solid particles, so that the solid-liquid mixture entering the distribution frame 11 has no agglomerated material. Through the action of a plurality of shunt blocks 16 at the lower end of the distribution frame 11, the solid-liquid mixture can be shunted, so that the solid-liquid mixture is evenly distributed on the upper end surface of the first filter belt 4. Moreover, when the first motor 9 drives the first filter belt 4 and the second filter belt 5 to move synchronously and reversely, the rotating disc 22 also rotates, and the inclined arc push block 23 continuously pushes the end of the limiting rod 18, and the action of the tension spring 20 can make the plurality of shunt blocks 16 continuously reciprocate at the lower end of the distribution frame 11, which can further improve the uniformity of the solid-liquid mixture distributed on the upper end surface of the first filter belt 4.

[0028] Reference Figure 3 , the solid-liquid mixture will move towards the arc baffle 10 under the transportation of the first filter belt 4, and finally move to the space between the first filter belt 4 and the second filter belt 5 guided by the arc baffle 10. With the transmission of the first filter belt 4 and the second filter belt 5, the two can be coated and extruded to treat the solid-liquid mixture. The water squeezed out will directly drop to the wet area position inside the equipment frame 1. When the water is squeezed out, the solid components between the first filter belt 4 and the second filter belt 5 will become mud cakes or mud blocks. With continuous transmission, the mud cakes or mud blocks can be scraped off by the straight bar 26 and dropped to the dry area position for centralized collection and treatment.

[0029] Because the first filter belt 4 and the second filter belt 5 are woven, the surface of the woven lines is obvious, when the two are extruded to the solid-liquid mixture of the bixbyite, the solid particles are also easy to be extruded into the woven gap of the first filter belt 4 and the second filter belt 5, and when the first synchronous gear 8 rotates, the ball block 30 can be pressed by the finger 34, the straight rod 26 with the snap ring 35 moves frequently, the outer surface of the first filter belt 4 and the second filter belt 5 is scraped by the snap ring 35, the woven lines are moved frequently, so that the solid particles remaining in the woven gap can also fall into the dry area for collection and treatment, and the collection effect of the solid substances of the bixbyite is improved.
