Detailed implementation manners

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] Please refer to together Figures 1 to 7, a pellet cooling device for double-wall corrugated pipes provided by the present utility model will be described below. The pellet cooling device for double-wall corrugated pipes includes a cooling box body 1 and several rows of material guiding components; there is a material passing channel 11 inside the cooling box body 1; a hopper 12 is connected to the top of the cooling box body 1, and the hopper 12 is used to accommodate the pellets produced by the granulator; a discharge pipe 13 communicating with the feed inlet of the screening device 2 is provided at the bottom of the cooling box body 1; several rows of material guiding components are arranged in the material passing channel 11 and are arranged along the height direction; each row of material guiding components includes several material guiding plates 3, and each material guiding plate 3 is inclined downward; wherein, the material guiding plates 3 of adjacent rows are arranged in a staggered manner.

[0029] Compared with the prior art, for the pellet cooling device for double-wall corrugated pipes provided by the present utility model, the hopper 12 can accommodate the pellets produced by the granulator, and the pellets fall from the discharge port of the hopper 12 into the cooling box body 1; since there are several material guiding plates 3 in the material passing channel 11 inside the cooling box body 1 and the material guiding plates 3 are inclined, the movement path of the pellets in the cooling box body 1 can be increased, thus facilitating the cooling of the pellets; since the cooling box body 1 is communicated with the feed inlet of the screening device 2 through the discharge pipe 13, the cooled pellets can directly enter the screening device 2, and the screening device 2 can screen the pellets; through the above settings of the present application, since the pellets are cooled in the cooling box body 1 and the discharge port of the cooling box body 1 is directly connected to the feed inlet of the screening device 2, compared with the cooling methods in the prior art, the cooling method of the present application can reduce the situation of the pellets flying out of the cooling box body, thereby reducing the waste of the pellets.

[0030] It should be noted that the hopper 12 can be supported by a support frame; the pellets produced by the granulator are discharged into the silo, and the feeding method of the hopper 12 can be feeding by negative pressure, that is, the hopper 12 and the silo are communicated through a negative pressure pipe, and the pellets in the silo are sucked into the hopper 12 by negative pressure adsorption to realize the feeding of the hopper 12. Negative pressure feeding is a prior art and will not be elaborated here.

[0031] In addition, after the pellets enter the cooling box body 1 from the hopper 12, the pellets will fall onto the material guiding plates 3 and move along the inclined direction of the material guiding plates 3. Through the above settings of the present application, the movement path of the pellets in the cooling box body 1 can be extended, thus facilitating the cooling of the pellets.

[0032] In some embodiments, as Figures 1 to 7 shown, each material guiding plate 3 is arranged in an inverted V shape, the high end of the material guiding plate 3 faces upward, and the two sides of the material guiding plate 3 are respectively inclined downward; each material guiding plate 3 straddles the material passing channel 11, and there is a gap 14 for the pellet channel between the material guiding plate 3 near the edge position and the side wall of the material passing channel 11.

[0033] Exemplarily, the material guiding plate 3 is arranged in an inverted V-shaped structure, which can guide the granular material to both sides; then the material guiding plate 3 in the next row continues to guide the granular material to both sides, thereby being able to extend the movement path of the granular material in the cooling box body 1 and facilitating the cooling of the granular material. The granular material in the cooling box body 1 finally enters the screening device 2 through the discharge pipeline 13.

[0034] It should be noted that there is a gap 14 between the material guiding plate 3 at the edge position and the side wall of the material passing channel 11, which can enable the granular material at this position to fall downward from the gap and reduce the granular material accumulated here.

[0035] In some embodiments, as Figures 1 to 7 shown, a cooling shell 4 is provided outside the cooling box body 1, and the cooling shell 4 is fixed on the cooling box body 1; a cooling air duct is formed between the cooling shell 4 and the cooling box body 1; wherein, a cooling fan 5 is arranged at the bottom end of the cooling shell 4, and an air outlet 41 is arranged at the top end of the cooling shell 4; alternatively, a cooling fan 5 is arranged at the top end of the cooling shell 4, and an air outlet 41 is arranged at the bottom end of the cooling shell 4. A plurality of heat dissipation fins 15 are provided on the outer wall of the cooling box body 1 in the cooling air duct.

[0036] This embodiment is described by taking the air outlet 41 arranged at the top end of the cooling shell 4 as an example; a cooling fan 5 is arranged at the bottom of the cooling shell 4 to make the air flow from the bottom to the top of the cooling shell 4, thereby enabling the air flow to exchange heat with the cooling box body 1 and cooling the cooling box body 1; by providing the heat dissipation fins 15 on the cooling box body 1, the heat dissipation effect can be improved. Through the above settings of the present application, the cooling capacity can be further improved, and it is convenient to cool the granular material in the cooling box body 1.

[0037] In some embodiments, as Figures 1 to 7 shown, an installation frame 6 is provided outside the cooling box body 1, and the installation frame 6 is used to connect with the screening device 2; the installation frame 6 includes a cross bar 61 and an inclined bar 62, and the cross bar 61 is fixed on the outer side wall of the cooling box body 1; one end of the inclined bar 62 is fixed at the connection position of the cross bar 61 and the cooling box body 1, and the other end of the inclined bar 62 is fixed on the screening device 2; the inclined bar 62, the screening device 2 and the cooling box body 1 form a triangular structure.

[0038] Exemplarily, the cooling box body 1 is fixed on the screening device 2 through the installation frame 6, which can reduce the overall floor area; the inclined bar 62 and the screening device 2 can be connected by a flange. After the inclined bar 62 is fixed to the screening device 2, the inclined bar 62, the screening device 2 and the cooling box body 1 form a triangular structure, which can improve the stability of the cooling box body 1.

[0039] In some embodiments, as Figures 1 to 7As shown, the mounting bracket 6 further includes a support member 63 for supporting the bottom of the cooling box body 1, and the support member 63 is used to be fixed on the screening device 2.

[0040] Exemplarily, by fixing the support member 63 on the screening device 2 and the support member 63 contacting the bottom of the cooling box body, the support member 63 can play a role in supporting the cooling box body 1, further improving the stability of the cooling box body 1.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
