Description

Machine tool cooling liquid treatment device Technical Field The invention relates to the technical field of machine tool machining, in particular to a machine tool cooling liquid treatment device. Background Machine tools are machines for manufacturing machines and machines, known as "industrial masters" or "working masters", which play a central role in modern manufacturing. The method processes metal or other materials by cutting, grinding, drilling, milling and the like, so that the workpiece obtains the required geometric shape, dimensional accuracy and surface quality. The method is widely applied to the fields of automobiles, aerospace, ships, electronic information equipment, mold manufacturing and the like, and is basic equipment for manufacturing supporting high-end equipment. The machine tool cooling liquid is a key industrial liquid used for cooling, lubricating, cleaning and rust prevention in the machining processes of metal cutting, grinding and the like, and can effectively improve the machining precision, prolong the service life of a cutter and ensure the operation safety. During machining such as cutting and grinding, the tool interacts with the workpiece to produce metal chips which are then mixed into the coolant. The chips form suspended particles in the coolant, which may scratch the machined surface upon re-spraying, resulting in an increased Ra value (poor surface roughness), especially affecting the finish of the high precision grinding machine. The traditional filtering mode is that the machine tool cooling liquid is filtered through the filter paper, so that the severe requirement of high-precision machining on the cleanliness of the cooling liquid can be effectively met, and the machine tool cooling liquid is particularly outstanding in the aspects of preventing the surface of a workpiece from being scratched, prolonging the service life of a cutter and guaranteeing the stable operation of a system. The filtering mode has strong applicability, supports various liquid treatments, can meet the requirement of filtering precision, and is easy to control the cost. The filtering mode has the following problems: Since the cost is affected by the filter paper, the filter paper is a disposable consumable, and is replaced frequently especially in a high pollution load state. Secondly, because the filter paper is soaked by the cooling liquid, the bonding force among the fibers is weakened, the tensile strength of the self material is insufficient, the filter paper is easily influenced by impurities in the cooling liquid, the filter paper is damaged, and the filtering effect is influenced. However, if the coolant is pre-treated in advance, the pre-treatment portion causes a part of the coolant to be carried and discharged, resulting in an increase in the consumption of the coolant. Disclosure of Invention According to the defects of the prior art, the invention provides the machine tool cooling liquid treatment device, which is used for pretreating cooling liquid before filtering filter paper, reducing larger metal chip impurities in the cooling liquid, preventing the filter paper from being damaged, standing the pretreated metal chip, storing a part of cooling liquid contained in the metal chip, returning the part of cooling liquid to the filter paper for secondary filtering, and reducing the loss of the cooling liquid. In order to achieve the above purpose, the invention is realized by the following technical scheme: A machine tool cooling liquid treatment device comprises a first liquid storage tank, a first circulating pump, a filter paper conveying mechanism, a paper loading mechanism, a deslagging mechanism and a standing and backflow mechanism, wherein the first circulating pump is arranged at one end of the first liquid storage tank in a erected mode, a liquid inlet of the first circulating pump is communicated with the first liquid storage tank, a liquid outlet of the first circulating pump is connected into the machine tool liquid storage tank, the filter paper conveying mechanism is arranged above the first liquid storage tank in a erected mode, the paper loading mechanism is arranged at the initial end of the filter paper conveying mechanism, the deslagging mechanism is arranged above the filter paper conveying mechanism in a erected mode, the deslagging mechanism is perpendicular to the filter paper conveying direction, the standing and backflow mechanism is arranged below the deslagging mechanism, and the standing and backflow mechanism drives collected cooling liquid above the filter paper. The filter paper conveying mechanism comprises a frame, driving rollers, a driving motor and a chain net, wherein the frame is fixed on two sides of a first liquid storage tank, the driving rollers are respectively arranged at two ends of the frame in a rotating mode, and the two groups of driving rollers support the chain net tightly and rotate along with the driving rollers.
