The cooling conveying mechanism 2 realizes the secondary cooling and anti-sticking operation of granulation, and the specific embodiment is as follows:
as shown in fig. 1 and 4, the cooling and conveying mechanism 2 includes a movable anti-sticking conveying assembly 21 disposed below the screw extruder, and a blast cooling assembly 22 disposed above the movable anti-sticking conveying assembly 21, and the sheared pellets fall to the movable anti-sticking conveying assembly 21 and are driven by the movable anti-sticking conveying assembly 21 to make reciprocating horizontal displacement so as to realize uniform pelletizing and anti-sticking functions.
The horizontal vector of the air outlet direction of the air-blast cooling assembly 22 is the same as the conveying direction of the movable anti-sticking conveying assembly 21, and the air-blast cooling assembly 22 is used for air-cooling the sheared granules.
The cooling mode of current conveying mechanism is the extension transport distance mostly, perhaps increases the fan on conveying mechanism and cools down, but this kind of condition exists the uneven condition of cooling, granulation cooling piece of upper strata and air contact promptly, be difficult to the adhesion, and the granulation of lower floor still is in the high temperature state, consequently still can appear the problem of adhesion, in order to solve above-mentioned problem, conveying mechanism of this embodiment is the transfer state, conveying mechanism can carry out reciprocating type horizontal migration promptly in order to realize the even and anti-sticking function of granulation.
The movable anti-sticking conveying assembly 21 comprises a first layer of conveying belt 211 arranged right below the screw extruder, a second layer of driving chain 212 arranged at the tail end of the first layer of conveying belt 211 and positioned below the first layer of conveying belt 211, and a material receiving cloth 213 arranged on the surface of the second layer of driving chain 212, wherein a plurality of push-pull cylinder groups 134 which are uniformly distributed and used for pushing the material receiving cloth 213 to move linearly in a reciprocating mode along the second layer of driving chain 212 are arranged between the second layer of driving chain 212 and the material receiving cloth 213.
The cut pellets are transferred to the receiving cloth 213 through the first layer of the conveyer belt 211 in a short distance, and the receiving cloth 213 is moved linearly in a reciprocating manner along the surface of the second layer of the driving chain 212 while being rotated in a circulating manner under the second layer of the driving chain 212.
In this embodiment, the conveying speed of the two-layer driving chain 212 is lower than the conveying speed of the one-layer conveying belt 211, and the conveying length of the one-layer conveying belt 211 is far less than the conveying length of the two-layer driving chain 212, so that the one-layer conveying belt 211 can convey the granules sheared at each time to the two-layer driving chain 212 in time, and the air-blast cooling assembly 22 of the two-layer driving chain 212 carries out the timely heat dissipation and cooling treatment, so that the purpose of the two-layer conveying in this embodiment is to avoid the accumulation of the granules just sheared by the one-layer conveying belt 211, the adhesion problem is likely to be caused by the accumulation of the granules which are not subjected to heat dissipation and cooling, and the heat dissipation time is prolonged by the two-layer driving chain 212 through reducing the conveying speed, so that the function of accelerating the cooling efficiency can be realized by combining the air-blast cooling assembly 22 even under the condition of reducing the conveying length of the two-layer driving chain 212.
Each push-pull cylinder group 134 is composed of two cylinders, the telescopic states of the two cylinders are opposite, and when one cylinder extends out to push the material receiving cloth 213, the other cylinder contracts to provide a redundant space for the movement of the material receiving cloth 213.

The material blocking rubber plate 8 is made of hard rubber and serves as a stress surface of the push-pull cylinder group 134, and meanwhile, granulation can be prevented from being scattered in the reciprocating shaking process.
The blast cooling module 22 includes a cover plate 221 disposed above the two-layer driving chain 212, and a plurality of fans 222 installed on the cover plate 221 in an inclined manner, wherein the inclined direction of the fans 222 faces the feeding direction of the two-layer driving chain 212, and the fans 222 are used for increasing the cooling efficiency when the material receiving cloth 213 moves linearly in a reciprocating manner along the surface of the two-layer driving chain 212.
According to the above, in the transmission process of granulation in this embodiment, the granulation is not stood on the surface of the material receiving cloth 213, the material receiving cloth 213 is rocked back and forth under the driving action of the push-pull cylinder group 134, and then granulation particles can rock back and forth between the material blocking rubber plates 8 of the material receiving cloth 213, so that the blast cooling assembly 22 can perform comprehensive heat dissipation operation on the granulation particles, thereby improving the heat dissipation efficiency and the heat dissipation uniformity, and further effectively reducing the conditions of granulation adhesion and granulation unevenness.
In addition, the inclined direction of the fan 222 faces the feeding direction of the two-layer driving chain 212, the feeding direction and the heat dissipation direction of the granulated particles are the same, and if they are different, the granulated particles may be scattered from the receiving cloth 213 by two opposite forces, so that the stable transportation of the granulated particles is ensured while uniform heat dissipation and efficient heat dissipation are achieved in the present embodiment.
The width of the first layer of the conveyer belt 211, the width of the receiving cloth 213 and the width of the sieving mechanism 3 are sequentially increased in an equivalent manner, and the width of the receiving cloth 213 is the sum of the width of the first layer of the conveyer belt 211 and the back-and-forth distance of the receiving cloth 213 in reciprocating linear movement along the surface of the second layer of the driving chain 212.
The width of the sieving mechanism 3 is the sum of the width of the material receiving cloth 213 and the back-and-forth distance of the material receiving cloth 213 reciprocating linearly along the surface of the two-layer driving chain 212.
Because the receiving cloth 213 makes reciprocating linear movement on the surface of the two-layer driving chain 212, the position of the receiving cloth 213 is movable and not fixed, so that in order to ensure that the receiving cloth 213 can still stably receive the granulation of the one-layer conveying belt 211 when moving, the width of the receiving cloth 213 needs to be larger than the width of the one-layer conveying belt 211, and the difference between the width of the receiving cloth 213 and the width of the one-layer conveying belt 211 is twice the linear movement distance of the receiving cloth 213, and similarly, the difference between the width of the sieving mechanism 3 and the width of the receiving cloth 213 is twice the linear movement distance of the receiving cloth 213 when the sieving mechanism 3 wants to stably receive the granulation when the receiving cloth 213 shakes, thereby effectively preventing the problem that the granulation particles fall.
When granulation and shearing are carried out, the end part of the granulation shell is cooled by spraying water to the cutter, the cutter is prevented from being adhered to the material body, and the adhesion probability among granulation particles is reduced; the second is as follows: in granulation granule transmission course, through rocking the radiating efficiency who improves the granulation with the granulation, avoid appearing the inhomogeneous condition of granulation heat dissipation, further improvement granule homogeneity and effectively prevent granule adhesion.
