The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
Embodiment:
Referring to Fig. 1 and Fig. 2; Present embodiment provide a kind of easy to operate, only need to produce for one time and can obtain the two rank of banburying up to specification electric cable material with low smoke and halogen free and produce unit, it stores and comprises on banbury, material elevator 20, conical double-screw feeder 30, the twin-screw the fervent granulation subsidiary engine of the board-like automatic net-changing device of rank extruder 50 under rank extruder 40, the single screw rod, hydraulic pressure 51, water ring die face 60, primary cyclone 70, secondary cyclone 80, vibratory sieve 90 and finished product storage bin 100 successively from being fed to finished product.
In the present embodiment, what banbury adopted is adding pressure type banbury 10, and it is to be used for rubber, plastic cement, and chemical raw material mixings banburying is processed, and mainly is used for carrying out the effect of the mixing dispersion of material.This adding pressure type banbury 10 adopts " M-W " adding pressure types and casting mixing channel, not only consolidates wear-resistingly, and guarantees that mixing of materials is average and all arrives mixing on year-on-year basis optimum efficiency with the rerum natura variation.
Material becomes the bulk material after 10 banburyings of adding pressure type banbury; This bulk material is gone in the hopper of material elevator 20 through the discharging opening overturning of adding pressure type banbury 10; Material elevator 20 pass through chain with mass transport to top after overturning go into conical double-screw feeder 30, this conical double-screw feeder 30 is used for the bulk material clamp-oned by force and disperses in the rank extruder 40 on the twin-screw with mixing; The spout of rank extruder 40 connects firmly mutually on its discharging opening and the twin-screw.
It should be noted that rank extruder 40 carries out material dispersed and mixing under the high temperature on the twin-screw, make the characteristic that more evenly and further changes material of mixing of materials; And carry out the conveying of material; Referring to Fig. 3, rank extruder 40 has used special twin-screw bi-conical feed cylinder 401 to dock with conical double-screw feeder 30 on the twin-screw of present embodiment.The twin-screw bi-conical feed cylinder 401 of present embodiment is provided with the endoporus that twin-screw is installed and is trapezoidal feeding connector 402; Be provided with the trapezoidal spout 403 that connects endoporus in the feeding connector 402; Trapezoidal spout 403 is suitable with the discharging opening of the two forced feed machines 30 of awl, and said endoporus is two crossing circular holes, and the cross section of said endoporus is for being the splayed ring structure; The utility model is suitable through the shape and the conical double-screw feeder 30 that improve trapezoidal spout 403; Be convenient to the cylindrical shell feeding, increased the production production capacity, improved efficient.
Rank extruder 50 is fed the material of coming with rank extruder on the twin-screw 40 and is mixed plasticizing once more under single screw rod, and it is better to make it performance; Its charging aperture is connected through the discharging opening of forcing rank extruder 40 on blanking transition body and the twin-screw, is provided with the blanking channel of circular arc in this pressure blanking transition body, and the feed opening of this blanking channel is provided with the charging aperture of blanking channel is vertical.Present embodiment forces to be pressed into down rank extruder under the list screw rod of rank through the material of forcing blanking transition body that rank extruder on the twin-screw 40 is carried, prevents the material not blanking that spins, and causes granulation inhomogeneous.The board-like automatic net-changing device 51 of hydraulic pressure also is installed in the discharging head of rank extruder 50 under single screw rod, carries out the filtration of impurity in the material, guarantee the quality of finished product materials.Be fixedly connected with comminutor on the discharging head of rank extruder 50 under single screw rod, what this comminutor adopted is the fervent granulation subsidiary engine 60 of water ring die face, and the strip-shaped materials that fervent head is extruded is cut into the shape of particle of regulation; Because the characteristic of material will quick pelletizing under the water spray state.The material that pelletizing is got off is delivered in the primary cyclone 70 through high pressure positive blower 61 and the conveyance conduit 101 of 5.5KW; This primary cyclone 70 is delivered in the secondary cyclone 80 through high pressure positive blower 71 and the corresponding conveyance conduit of 4KW again; The finished product materials that pelletizing is got off makes the cooling of material through the primary cyclone 70 and second cyclone separator 80; And blow in the process through high pressure positive blower; The collision of material and conveyance conduit and cyclone separator barrel separates material each other.
Vibratory sieve 90 is installed at the discharging opening place of secondary cyclone 80; Vibratory sieve 90 is arranged on the below of secondary cyclone 80; Through secondary cyclone 80 cool off once more with separate after material in its feed opening gets into vibratory sieve 90; Be used for material screening, irregular (excessive or too small) particle screening is fallen, only particle up to specification high pressure positive blower 91 and conveyance conduit through 3KW is delivered to finished product storage bin 100, and through the further cooled materials of blowing of cooling blower; This finished product storage bin 100 is used for the storage of finished product materials, so that pack is handled.
Present embodiment is a line mode of production when using; Only need material is added in the adding pressure type banbury 10; Then progressively through rank extruder, the board-like automatic draping of hydraulic pressure, the fervent comminutor of air-cooled die face, primary cyclone 70, secondary cyclone 80 and vibratory sieve 90 under rank extruder 40, pressure blanking transition body, the single screw rod on material elevator 20, conical double-screw feeder 30, the twin-screw; Finally be transported to finished product storage bin 100 and store, so that pack is handled.
The utility model has avoided existing unit to produce electric cable material with low smoke and halogen free need carry out the extruder operating process twice, has reduced the flow process of producing, and has practiced thrift production cost; The utility model only needs can produce an electric cable material with low smoke and halogen free up to specification, the output that the electric cable material with low smoke and halogen free particle of making can double with the mode on banburying pair rank, and also whole process is except that the finished product materials that feeds intake and pack; Do not need manual work, reduced labour intensity, workshop condition can be greatly improved; Do not have very big dust and noise; Simultaneously it has simple to operately, easy to use, has reduced the advantage of cost, energy-conserving and environment-protective.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined
