Description

Cooling device of PVC aggregate

Technical Field

The utility model relates to a PVC production technology especially relates to a cooling device of PVC aggregate.

Background

The PVC aggregate has the waste heat after producing, if not cool off just packing, thereby can seal the heat in the wrapping bag and produce moisture, lead to the product disability rate to rise from this, does not have the professional equipment who is used for cooling down after the PVC aggregate production specially among the prior art, consequently designs a professional equipment who is used for cooling down after the PVC aggregate production and becomes a research and development direction of this trade.

Disclosure of Invention

The utility model provides a cooling device of PVC aggregate to solve among the prior art PVC aggregate and not cool off just packing, thereby can produce moisture with the heat seal in the wrapping bag, lead to the problem that the product disability rate rises from this.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a cooling device of PVC aggregate, includes casing, feeding funnel, discharging pipe, be equipped with the cooling chamber in the casing, the feeding funnel set up in the casing upper end and with cooling chamber intercommunication, the discharging pipe set up at the casing lower extreme and with cooling chamber intercommunication, be equipped with spiral slideway in the cooling chamber the periphery in cooling chamber is around being equipped with the condenser pipe along the cooling chamber. The spiral slideway is spiral, so that the heat dissipation area is large, the track is long, and PVC granules can be gradually cooled. PVC aggregate gets into the cooling chamber from the feeding funnel, through spiral slideway cooling temperature reduction again, the condenser pipe of cooling chamber periphery is to the inside cooling temperature reduction of cooling chamber, and the PVC aggregate after the cooling is followed discharging pipe 3 ejection of compact.

Further, an air cooling pipe is arranged in the center of the spiral slideway along the axis direction, and an axial flow fan is arranged at the lower end of the air cooling pipe. The axial flow fan blows air upwards from the bottom end of the air cooling pipe, and the air is matched with the rising of hot air to take away heat in the middle of the cooling cavity.

Furthermore, a plurality of steam exhaust holes are formed in the air cooling pipe. PVC aggregate in the cooling cavity can produce steam in the cooling process, and the steam can be upwards discharged through the steam discharge hole on the air cooling pipe.

Furthermore, a copper sheet is coated on one side of the condensation pipe close to the cooling cavity. The copper sheet serves to separate the PVC pellets from the condenser tube and allows the condenser tube to rapidly exchange heat with the PVC pellets.

Further, a conveyor belt is arranged below the discharge pipe, one end of the conveyor belt is arranged below the discharge pipe, and a blanking groove is formed in the other end of the conveyor belt. And the PVC granules fall to a conveyor belt from the discharge pipe, and the PVC granules still have residual temperature and fall into a blanking groove after being cooled to room temperature on the conveyor belt.

After the technical scheme is adopted, the utility model has the advantages of as follows:

the utility model discloses a cooling device of PVC aggregate can fully cool off the PVC aggregate, thereby can avoid sealing the heat and produce moisture in the wrapping bag, and the condition that leads to the product disability rate to rise takes place.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1, the cooling device for the PVC granules comprises a shell 1, a feeding hopper 2 and a discharging pipe 3, wherein a cooling cavity 4 is arranged in the shell 1. The feeding hopper 2 is arranged at the upper end of the shell 1 and communicated with the cooling cavity 4, the discharging pipe 3 is arranged at the lower end of the shell 1 and communicated with the cooling cavity 4, the spiral slideway 5 is arranged in the cooling cavity 4, and the condensing pipe 6 is wound on the periphery of the cooling cavity 4 along the cooling cavity 4. The spiral slideway 5 is spiral, so that the heat dissipation area is large, the track is long, and PVC granules can be gradually cooled.

The side of the condensation pipe 6 close to the cooling cavity 4 is coated with a copper sheet 10. The copper sheet 10 functions to isolate the PVC pellets from the condensation duct 6 and allows the condensation duct 6 to rapidly exchange heat with the PVC pellets. PVC aggregate gets into cooling chamber 4 from feeding funnel 2, through 5 cooling temperature of spiral slideway again, and 4 periphery condenser pipes 6 of cooling chamber are to 4 inside cooling temperature in cooling chamber, and the PVC aggregate after the cooling is followed discharging pipe 3 ejection of compact.

In this embodiment, the below of discharging pipe 3 is equipped with

conveyer belt

11, and 11 one end settings of conveyer belt are in discharging pipe 3 below, and the 11 other ends of conveyer belt are equipped with blanking groove 12. PVC granules fall out to conveyer belt 3 from discharging pipe 3, and the PVC granules still have the residual heat at this moment, after cooling to room temperature on conveyer belt 11, fall into charging chute 12.

To sum up, this cooling device of PVC aggregate can fully cool off the PVC aggregate, thereby can avoid sealing the heat in the wrapping bag and produce moisture, lead to the condition emergence that the product disability rate rises.

In addition to the preferred embodiments described above, other embodiments of the present invention are also possible, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope of the present invention defined by the appended claims.
