Embodiment Construction

[0052] In order to further explain the technical solutions of the present invention, specific examples are given below to illustrate in detail.

[0053] A device for recovering and treating oily sewage after the aluminum profile extrusion die is cleaned, such as Figure 1-7 As shown, along the oily sewage treatment line, the gravity separation mechanism 1, the slow flow sedimentation mechanism and the oil collection tank are sequentially included.

[0054] The gravity separation mechanism 1 comprises a barrel body 11 containing oily sewage and having a relatively thick diameter, an oil-collecting thin-diameter tube 12 with a thinner diameter arranged on the upper end of the barrel body 11, connected between the barrel body 11 and the oil-collecting thin-diameter tube 12 and A tapered transition section 13 that gradually becomes thicker from top to bottom, and a pressurizing device 14 provided at the lower part of the barrel body 11 to pressurize the barrel body 11;

Abstract

The invention provides a recovery treatment device of oily sewage obtained after cleaning of an aluminum profile extrusion die. In the actual use process, a gravity separation mechanism is firstly used for performing oil-water separation on sewage, then, a slow flow settling mechanism is used for performing impurity settlement and adsorption on oil, and clean oil is obtained and collected in an oil collection box. When an oil layer enters the slow flow settling mechanism from an oil inlet, the flow channel firstly gets wide, then, the oil layer starts to distribute and disperse, and impuritiesin the oil layer are gradually deposited on an impurity adsorption layer; multiple concave pits and convex columns are formed on the impurity adsorption layer of a settling box and can hinder flowingof the oil layer, and the flow speed of the oil layer is further reduced; the contact area of the impurity adsorption layer and the oil layer can be enlarged, the contact time of the impurity adsorption layer and the oil layer can be prolonged, and the adsorption effect of the impurity adsorption layer on impurities in the oil layer is enhanced; naturally falling or adsorbed impurities can be deposited in the concave pits, and the condition that the adsorption effect is affected due to the fact that the oil layer flows and carries away the impurities is avoided; the oil layer treated by the slow flow settling mechanism can flow out of an oil outlet and can be collected and stored by the oil collection box.

Description

technical field [0001] The invention relates to the field of oily sewage treatment equipment, in particular to a recovery and treatment device for oily sewage after cleaning an aluminum profile extrusion die. Background technique [0002] Aluminum profile extrusion die After the aluminum profile extrusion process is completed, the aluminum profile extrusion die needs to be cleaned. The cleaned sewage contains a lot of oil, and the oily sewage needs to be treated to avoid oil residue and pollute the environment. At present, there are mainly three types of treatment methods for oily sewage after cleaning aluminum extrusion dies at home and abroad: chemical treatment, physical treatment and biochemical treatment. Among them, the physical treatment method does not require additional additives, and the equipment can be used repeatedly. The overall cost is relatively low, and it is the most used method. For the treatment of large quantities of oily sewage, more centrifugal separa...
