Engagement cooling apparatus of extruder

Abstract

The invention relates to an engagement cooling apparatus of an extruder. The apparatus comprises a driving shaft and a driven shaft which are horizontal and are arranged in a mutual parallel manner; gear sleeves are sleeved on the driving shaft and the driven shaft respectively; a plurality of water slots are arranged between the driving shaft or the driven shaft and the gear sleeves; one end of each of the driving shaft and the driven shaft is provided with a water inlet hole, and the other end of each of the driving shaft and the driven shaft is provided with a water outlet hole; water inlet holes and water outlet holes are respectively connected with two ends of the water slots; the driving shaft and the driven shaft are correspondingly arranged on a support; the bottom of the support is provided with a water tank; one side of the support close to the water inlet holes is provided with at least one cooling water pump; the cooling water pumps are connected with the water tank through water suction holes; the cooling water pumps are respectively connected with the water inlet holes through water inlet tubes; and each of the water outlet holes is connected with the water tank through a water outlet tube. The apparatus improves the product cooling speed by increasing the extrusion area.

Description

technical field [0001] The invention relates to an engaging cooling device for an extruder. Background technique [0002] In the paint industry, the extruder needs to use a cooler to extrude and cool the viscous and high-temperature semi-finished product during production, and make it into a thin sheet for the next step; and the existing cooler is low in cost due to the wide range of water sources Most of them use water cooling, by setting water tanks parallel to the axis on the inner wall of the driving shaft and the driven shaft, and setting multiple baffles placed at intervals in the water tank, so that the cooling water flows in the driving shaft and the driven shaft. Prolong the residence time of the cooling water in the driving shaft and the driven shaft under the obstruction of the baffle, so that the cooling water and the high-temperature semi-finished product can fully exchange heat; but this method will prolong the cooling water in the driving shaft and the driven ...

[0002] In the paint industry, the extruder needs to use a cooler to extrude and cool the viscous and high-temperature semi-finished product during production, and make it into a thin sheet for the next step; and the existing cooler is low in cost due to the wide range of water sources Most of them use water cooling, by setting water tanks parallel to the axis on the inner wall of the driving shaft and the driven shaft, and setting multiple baffles placed at intervals in the water tank, so that the cooling water flows in the driving shaft and the driven shaft. Prolong the residence time of the cooling water in the driving shaft and the driven shaft under the obstruction of the baffle, so that the cooling water and the high-temperature semi-finished product can fully exchange heat; but this method will prolong the cooling water in the driving shaft and the driven shaft at the beginning of the work. The residence time in the shaft, once the cooling water in the water tank is full, the residence time of the cooling water in the driving shaft and the driven shaft will be very short, and the effect of exchanging heat will not be achieved. For this reason, we have developed a through The intermeshed cooling device of the extruder that increases the contact area to fully exchange heat, thereby improving the cooling effect
