Abstract
The utility model discloses a centrifugal disk for a spray granulator. The centrifugal disk an upper end disk, a lower end disk and a connection columns, wherein the upper end disk and the lower end disk are distributed coaxially, the connection columns are evenly distributed along the peripheral direction and fixedly connected between the upper end disk and the lower end disk, each connection column is respectively, detachably and fixedly connected between the upper end disk and the lower end disk through screws or bolts, each connection column is provided with a through hole for rod portions of the screws or the bolts to penetrate through, and the upper end disk and the lower end disk are respectively provided with installation holes which correspond to all through hole in a one to one mode and are matched with the screws or the bolts. All connection columns are detachably and fixedly connected with the upper end disk and the lower end disk through screws. If the connection columns are abraded seriously, only the connection columns are replaced so as to be convenient, avoid whole abandonment of the centrifugal disk and save materials.
Description
Technical field
The utility model relates to a kind of sponging granulator centrifugal disc, is specifically related to the application of pressureless sintering carborundum on centrifugal disc.
Background technology
Centrifugal disc claims again atomizing disk; it is the critical component of sponging granulator; comprise the circumferential uniform joint pin in edge on the upper and lower end disk of coaxial setting and the opposing end surface that two ends are separately fixed at the upper and lower end disk; each joint pin is joined together to form overall structure with the upper and lower end disk; and each joint pin is near the marginal position of upper and lower end disk, so that centrifugal disc forms one by one circumferential spaced apart spray holes at marginal position.During work, under the centrifugal action of centrifugal disc High Rotation Speed, the periphery that will be thrown to by the slurry that distributor is carried centrifugal disc forms film, and film goes out to be shredded into droplet afterwards from the spray holes impelling again.
Traditional centrifugal disc generally adopts stainless steel material to make, be used for hardness and be not the centrifugal atomizing of too high slip, if when being used for the centrifugal atomizing of silicon carbide slurry, then following problem can appear: 1, the stainless steel centrifugal disc is when work, be subject to the impact of silicon carbide slurry, because the hardness of carborundum itself is high, wearing and tearing to centrifugal disc are very large, and joint pin is the most serious positions of centrifugal disc wearing and tearing, along with the growth of access times and time, so that the atomizing effect variation, serious even affect yield rate, therefore, stainless steel centrifugal disc general work was less than 100 hours; 2, wearing and tearing have a small amount of powder of stainless steel and enter in the granulation material, have produced secondary pollution; 3, the stainless steel centrifugal disc adopts and is wholely set, and the joint pin serious wear is scrapped centrifugal disc integral body, causes waste of material.
The utility model content
The purpose of this utility model provides a kind of sponging granulator centrifugal disc, the easy problem of wearing and tearing of joint pin that adopts stainless steel material to cause in order to solve existing centrifugal disc.
The utility model adopts following technical scheme: a kind of sponging granulator centrifugal disc; comprise the upper and lower end disk of coaxial arrangement and be fixedly connected on the circumferential uniform joint pin in edge between the upper and lower end disk; each joint pin is removably fixed with by screw or bolt and upper and lower end disk respectively; described each joint pin has the through hole that passes for the bar section of screw or bolt, described upper and lower end disk have respectively with each through hole one to one and the pilot hole that cooperates with screw or bolt.
The unthreaded hole that each pilot hole on the described lower end disc passes for the bar section of the counterbore that sinks to head for each self-corresponding screw or bolt respectively and the confession screw that is communicated with counterbore or bolt, each pilot hole on the described upper end disc is the screwed hole that cooperates with each self-corresponding screw or bolt thread respectively.
The material of described joint pin adopts carborundum.
Adopt the sponging granulator centrifugal disc of said structure, because the material of joint pin adopts carborundum, the intensity of carborundum is higher than stainless intensity, thereby has improved the wearability of joint pin, has prolonged the service life of joint pin even whole centrifugal disc; Each joint pin is removably fixed with by screw and upper and lower end disk respectively simultaneously, even the more serious phenomenon of wearing and tearing occurs joint pin, gets final product by changing joint pin, and is very convenient, avoided centrifugal disc integral body to scrap, and saved material; In addition, adopt the joint pin of carbofrax material, the silicon carbide powder that wearing and tearing produce can not cause the secondary pollution of silicon carbide slurry.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the structural representation of the joint pin among Fig. 1.
The specific embodiment
The utility model sponging granulator embodiment of centrifugal disc: as shown in Figure 1 and Figure 2; comprise end disc 1, lower end disc 2 and joint pin 5; upper end disc 1 and the coaxial setting about in the of 2 of lower end disc; and employing stainless steel material; joint pin 5 is circumferential uniform a plurality of along two disks; the two ends of each joint pin 5 are connected with the opposing end surface of upper end disc 1 and lower end disc 2 respectively; and each joint pin 5 near the marginal position of two disks, has formed spray holes between two adjacent joint pins respectively.Above part is prior art or can realizes by prior art, improvements of the present utility model are: the material of described joint pin 5 adopts carborundum, the coaxial through hole 51 that offers respectively on the end face of each joint pin 5, offer respectively on upper end disc 1 and the lower end disc 2 and each through hole pilot hole one to one, wherein, each pilot hole of upper end disc 1 is screwed hole, each pilot hole of lower end disc 2 is counterbore and the unthreaded hole that is communicated with counterbore, penetrate corresponding counterbore by the bar section with screw, unthreaded hole, in through hole and the screwed hole, can realize being removably fixed with of each joint pin and upper end disc and lower end disc, and the head of screw sinks in the counterbore finally.
In the present embodiment, joint pin 5 adopts the production technology of pressureless sintering, technological process is: compacting → sintering → mill processing → polishing → check, specific process is: select pelletizing compressing on hydraulic press, after transferring to the sintering of sintering mill (plant) through 2000 ℃ of-2250 ℃ of high temperature, reach required density, hardness number; The low precision of the ripe base of carborundum behind the sintering can not be satisfied the demand, so next step is that this ripe base is ground processing; After the processing of the peripheral milling of silicon carbide components, the centrifugal disc on sponging granulator is installed, and regulation moving balance after installing can be used after qualified.
In the present embodiment, the outside dimension in the same size of upper end disc 1 and lower end disc 2, wherein going up end disc 1 is loop configuration, one is coaxially arranged with the boss 4 of cylindrical structure on the upper surface of lower end disc 2, the external diameter of boss 4 is less than the internal diameter of upper end disc 1, and after in the endoporus of boss 4 end disc on stretching into, its upper surface is concordant with the upper surface of upper end disc 1, and the gap between boss 4 and the upper end disc 1 has formed annular charging aperture 3 like this.
When above-described embodiment is specifically used, the silicon carbide slurry of being carried by distributor is entered in the centrifugal disc by charging aperture 3, under the centrifugal action of centrifugal disc self High Rotation Speed, the periphery that silicon carbide slurry is thrown to centrifugal disc forms film, and film goes out to be shredded into droplet afterwards from the spray holes impelling again.
