Abstract
The invention relates to an unround ceramsite and a preparation system thereof. The ceramsite is shaped as an unround ball, such as a regular triangular prism or a regular quadrangular prism, and a rough surface is preferred for the surface of the ceramsite. The preparation system comprises a spiral extruder and a cutting mechanism; a discharging port of the spiral extruder is provided with a forming disc which is provided with a plurality of unround forming through holes; the cutting mechanism is provided with a cutter which is matched with the forming disc so as to form a cutting pair together for cutting the materials extruded from the forming through hole; when the materials are extruded out of the forming disc, the blade cuts off strip-shaped materials along the surface of the formingdisc to form particles; and the particles form hard ceramsite after being sintered or dried. The ceramsite greatly increases the contacting and functioning opportunity of pollutants in water with active sludge, has obvious positive function for improving the reaction efficiency and is mainly used for water treatment.
Description
Technical field
The present invention relates to a kind of Unround ceramsite and preparation system thereof, be mainly used in water treatment system, belong to environmental technology field.
Background technology
Haydite is a kind of common materials in the water treatment, can be used for various aerobic and anaerobic biofilm treatment system, the active sludge that plays a major role in biological treatment is attached to the surface, space of haydite surface or haydite inside, improved the biological density in the system for handling thus, improved the performance of active sludge, and then increase substantially processing efficiency and improve treatment effect significantly, although haydite can adopt different starting materials and can be by multiple different prepared, but a general character is arranged wherein, all be that wet feed material is made spheroidal by shaped device, carry out hyperthermia drying or high temperature sintering according to raw material properties then, formation has the solid ball of certain intensity, a major defect of this spherical haydite is after being deposited in haydite together, because the globosity of haydite, all be a contact basically between the adjacent spherical haydite, very close to each other or the gap is too small on point of contact, form " current dead angle " that current can't pass through, and discontiguous zone is that an all directions size is all bigger, the formation current do not reach " the reaction dead angle " attached to the active sludge on haydite surface basically, and this " reaction dead angle " is interconnected, resistance to current is little, therefore in considerable portion of time, current are mobile in the space that does not reach haydite surfactivity mud basically, have greatly restricted the performance of microbial film effect thus.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides the preparation system of a kind of Unround ceramsite and this Unround ceramsite, adopt this haydite can improve gap between the haydite, reduce current dead angle and reaction dead angle in the water treatment procedure.
The present invention realizes that the technical scheme of above-mentioned purpose is:
A kind of Unround ceramsite, its profile is non-spheroidal.
A kind of preparation system of Unround ceramsite, comprise screw extrusion press and cutting mechanism, the discharge port of described screw extrusion press is provided with forming disk, described forming disk is provided with the forming through hole of some non-circles, described cutting mechanism is provided with cutter, described cutter cooperates with described forming disk, is configured for shearing the shearing pair of the material of extruding from described forming through hole jointly.
Because the present invention is designed to non-spherical with haydite, it is prismatic particularly can be designed to regular triangular prism, regular prism etc., after this haydite piled up, the side of most of haydite is parallel to each other, gap between the haydite is smaller, current during by these gaps can with contact attached to active sludge on the haydite surface of both sides, gap, greatly increased contact and the effect chance of water pollutant thus with active sludge, to improving reaction efficiency tangible active effect is arranged.

Fig. 2 is the profile synoptic diagram of haydite of the present invention;
Fig. 3 is the schematic flow sheet of preparation system of the present invention.
Embodiment
Referring to Fig. 2, haydite of the present invention is that the spheroidal under the prior art is changed into different spherical, and other are non-circular, so-called non-circular other three-dimensional shapes that are meant except that spheroidal.
According to the facility of processing and preparing, can adopt various prisms usually, preferably be convenient to process and can satisfy multi-edge column-shapeds such as the regular triangular prism of service requirements and four-prism, particularly positive multi-edge column-shaped well.
For ease of using, what each seamed edge on the described haydite can be for slyness, the surface of haydite can be crude surface, these constructional features can realize by the surface grinding of haydite.
The present invention can adopt various suitable materials and formulation haydite, and owing to the profile of principal feature of the present invention at haydite, therefore except moulding process, other technologies can adopt existing technology mostly.
Participate in Fig. 1 and Fig. 3, preparation system of the present invention mainly is the screw extrusion press and the cutting mechanism of molding process, the discharge port of described screw extrusion press is provided with forming disk 4, described forming disk is provided with the forming through hole of some non-circles, described cutting mechanism is provided with cutter, described cutter cooperates with described forming disk, is configured for shearing the shearing pair of the material of extruding from described forming through hole jointly.
Described cutter can comprise one or more rotating blades 6, described rotating blade is connected on the rotary tool axis 7, described rotary tool axis drives with shear motor 8 and is connected, by shear motor driven rotary blade rotation, the outside of described rotating blade inswept described forming disk when rotating, and leave small shear gap between the forming disk.When material was squeezed out forming disk, material was strip and stretches out from forming disk, and rotating blade is pasting the rotation of forming disk surface, just the strip material is cut off along the forming disk surface, forms particle (base of haydite before sintering or drying) one by one.Can be provided with a lot of forming through hole on the forming disk, can cut out a lot of particles thus simultaneously, the rotation of rotating blade can be step, whenever the rectangular arrival of extruding is sheared once to a certain degree the time.
Described cutter also can comprise the translation double-edged blade, described translation double-edged blade connects the translation transmission rig, described translation transmission rig connects shears drive-motor, driving described translation double-edged blade moves back and forth in the described forming disk outside, and leave small shear gap between the forming disk, this blade by translation shear from forming disk extrude rectangular.
