The invention discloses a total-synthesis metal working fluid composite lubricant as well as a preparation method and application thereof. In the composite lubricant, a main lubricant is PIBSA polyether ester, a dispersing agent is oleyl alcohol polyoxyethylene ether 10-maleate, and a soaping agent is oleic acid; the main lubricant and the dispersing agent are respectively prepared, and are compounded with the soaping agent according to the hard water concentration. The preparation method is simple and feasible, and is suitable for large-scale production; the prepared total-synthesis metal working fluid composite lubricant has a low-foam lubrication effect, has good heat storage stability and anti-rust performance in practical application, and has great industrial application prospects.

This utility model discloses a phosphate rock slurry filtration device, belonging to the field of phosphate rock processing technology. It includes a filter box and filter plates located within the filter box. The bottom of the filter box is provided with a corrugated bottom plate, which includes multiple adjacently arranged recesses and protrusions. Each protrusion corresponds to a filter plate, and the filter plate is inserted into the protrusion. Each recess has an inlet on one side and an outlet on the other side. This utility model, through the corrugated bottom plate and multiple filter plates located on the protrusions, can effectively filter the slurry while ensuring that filtered impurities settle in the recesses, reducing secondary filtration and improving the overall filtration effect of the filter box. Furthermore, the filter plates can be easily removed from the chute and slot for cleaning or replacement by lifting them.

A pollution discharge device body is arranged at the lowest position of a water sump in a drainage system and comprises a controller and a water tank which are arranged in the water sump, a plurality of layers of filter screens are arranged at the bottom of an inner cavity of the water tank, a plurality of layers of filter partition plates are arranged at the tops of the filter screens, and water pumps are arranged at the tops of the filter partition plates. A blow-off pipe penetrates through the side wall of the water tank, the water outlet end of the blow-off pipe is communicated with the drainage pipeline, and the water inlet end of the blow-off pipe is communicated with the water outlet end of the water pump through a tee joint; a water level inductive switch is arranged on the inner wall of the water tank above the filtering partition plate and is electrically connected with the signal input end of the controller, and the signal output end of the controller is electrically connected with the water pump; a lifting assembly is arranged above the water tank and comprises a guide chain, and the tail end of the guide chain is connected with hanging lugs symmetrically arranged on the top of the water tank through steel wire ropes. A filter screen and a filter partition plate are used for filtering for multiple times, so that sludge and water are separated, and practicability and convenience are achieved.

The invention provides a customer classification method and system, which can be used in the financial field or other fields, and the method comprises the steps: obtaining mechanism feature data of a financial mechanism and feature data of a target feature type corresponding to a to-be-processed customer; determining a classification result of the to-be-processed customer according to mechanism feature data of the financial mechanism, feature data of the target feature type and a preset classification model; the target feature type is obtained by applying a first feature screening mode or a second feature screening mode in advance; the preset classification model is obtained by pre-training a fuzzy clustering algorithm based on the feature data set. According to the invention, the efficiency and reliability of customer classification can be improved, and the reliability of subsequent deposit business processing can be improved.

The invention discloses an impurity removal type gas-liquid diverter for propylene carbonate production and processing, which aims at hydraulic pressure generated in the injection process of propylene carbonate mixed liquid, is matched with a spiral sheet group to adaptively rotate under the action of the hydraulic pressure, and has the key purpose of prolonging the flow distance of the propylene carbonate mixed liquid and improving the production efficiency of the propylene carbonate mixed liquid. The heating template provides a heat source in the flowing process of the propylene carbonate mixed liquid to ensure that gas dissolved in the propylene carbonate mixed liquid is separated out, and in the process, on one hand, the separated-out gas is transferred into the gas-liquid separation pipe through the combination of the fall pipe and the liquid level balance principle; and the hydraulic pressure during injection of the propylene carbonate mixed liquid is further utilized, and the key purpose is that the separated gas is ensured to be discharged in an independent liquid manner by utilizing the difference value between the gas pressure generated by the gas and the hydraulic pressure of the propylene carbonate mixed liquid.

The utility model discloses a cyclohexane oxidation tail gas separation pretreatment device relates to chemical industry waste gas treatment technical field, including cooling water tank still includes: circulating mechanism, the circulating mechanism sets up in cooling water tank, the circulating mechanism includes the cooling cylinder of setting in cooling water tank, the circulating mechanism is used for when the salt class is separated, the salt class of gaseous is cooled down, the cooling water of the utility model absorbs heat can flow into cooling water tank, when the cooling water passes through the fin, heat will be transferred from the cooling water to the fin, and the fin will transfer heat from the air outside, so that the cooling water in the cooling cylinder and cooling water tank will continuously circulate the cooling of cyclohexane oxidation tail gas in the conical hollow cylinder, ensure that the gaseous salt class in cyclohexane oxidation tail gas separates as solid to the inner wall of conical hollow cylinder, when the airflow rotates in the conical hollow cylinder, and the solid salt separated from the bottom of conical hollow cylinder is discharged, so as to realize the separation of salt class.
