Efficient drying room for drying EPP product

Abstract

The invention discloses an efficient drying room for drying an EPP product. The efficient drying room comprises a room body built on the ground and a steam supply pipeline; the steam supply pipeline conveys steam to the room body from a steam supply source; the efficient drying room is characterized in that a concave cavity is dug in the ground in the room body; a cover plate provided with meshescovers the concave cavity; the efficient drying room further comprises an airflow circulation radiating mechanism; the airflow circulation radiating mechanism comprises a draught fan and a radiating air bellow arranged outside the room body, a bottom wind pipe arranged in the concave cavity and provide with an air supply outlet, an S shaped thread radiating pipe below the bottom wind pipe, and a top wind pipe arranged on the top of the interior of the room body and provided with a return air inlet; the radiating air bellow is provided with an air bellow air inlet connected with the air outletof the draught fan and an air bellow air outlet connected with the bottom wind pipe via a pipeline; the air inlet of the draught fan is connected with the top wind pipe via a pipeline; an S shaped radiating copper pipe is arranged in the radiating air bellow; one end of the radiating copper pipe is connected with the steam supply pipeline; and the other end of the radiating copper pipe is connected with the S shaped thread radiating pipe via a pipeline. The efficient drying room is better in drying uniformity for the EPP product, is higher in drying efficiency, saves steam and reduces the production cost.

Description

technical field [0001] The invention relates to a high-efficiency drying room for drying EPP products. Background technique [0002] In the known technology, after EPP is granulated by extrusion and manufactured into products through a molding machine and a mold, due to the moisture on the product, it often needs to be dried intensively at the end, and the drying process is also a process for further curing of EPP. , can eliminate the internal stress of EPP and make the product structure more stable. The current practice is to discharge the product onto cart racks and place it in a drying chamber for drying. [0003] The traditional drying room is to open vents around the room and use natural wind to dry the EPP products, but the disadvantage is that the efficiency is too low, and the temperature is not easy to control, which affects the delivery time. [0004] For this reason, the design of steam drying is introduced in the prior art, that is, steam heat dissipation pipes...

AI Technical Summary

Problems solved by technology

[0005] (1) The uneven distribution of hot air inside the drying room makes the EPP products in the drying room heated unevenly and the drying time is not uniform

Often the EPP products in the surrounding areas have been dried, but the products in the middle area are still wet, which greatly affects the shipment uniformity of the same batch of products; repeated drying operations are often required

[0006] (2) The external airflow introduced by the fan is often mixed with moisture. While disturbing the hot air, it weakens the drying efficiency of the hot air, reduces the drying efficiency of the product, and affects the curing effect of the product

[0007] (3) Due to low drying efficiency, slow temperature rise, and poor efficiency, existing drying rooms often need to prolong the drying time and increase the amount of steam used, resulting in an increase in the production cost of the enterprise
