Heat radiation drainage passage for extrusion forming machine drainage system

Abstract

The invention provides a heat radiation drainage passage for an extrusion forming machine drainage system, and aims at solving the problem that in the prior art, when the drainage passage is used for filtering water, the unsmooth water flow can be easily caused. The heat radiation drainage passage comprises a passage which is connected with a drainage pipe and is arranged on the ground, wherein the passage consists of a first passage, a second passage, a third passage and a fourth passage which are sequentially connected, the first passage is a straight passage connected with the water discharge pipe, the second passage consists of three parallel sub passages, a first filtering net is arranged in the middle sub passage, an inlet of the third passage is provided with a second filtering net, and the fourth passage is a straight passage. The second passage consists of three parallel sub passages, the middle sub passage is aligned with a first passage groove, water flow mainly flows from the middle sub passage, and when the middle sub passage is blocked, the water flow mainly flows from the sub passages at two sides; major waste materials are filtered by the first filtering net, and a few of waste materials are filtered by the second filtering net; the waste materials are filtered, and in addition, the smooth water flow is ensured.

Description

technical field [0001] The invention relates to a heat dissipation drainage channel for a drainage system of an extrusion molding machine. Background technique [0002] At present, the extrusion molding machine needs water to cool down when the workpiece is extruded. In order to save water resources, it is necessary to use drains to cool down the water; Filter the water to prevent damage to the equipment used for subsequent circulation; because when there is a lot of waste accumulated on the front side of the filter, the water flow will not be smooth, causing water to overflow from the drainage channel and affect the subsequent work. Contents of the invention [0003] The invention provides a heat-dissipating drainage channel for a drainage system of an extrusion molding machine, aiming at solving the problem in the prior art that the drainage channel easily causes unsmooth water flow when filtering water. [0004] In order to solve the above technical problems, the prese...
