Description

TECHNICAL FIELD

[0001] The utility model relates to filter device technical field, specifically is a kind of processing equipment filter device. BACKGROUND

[0002] In modern industrial production, numerical control machine tool and polishing equipment etc. are important processing tools. When numerical control machine tool is precisely machined, cooling liquid circulating device is needed to ensure the smooth progress of machining process and the cooling of tool, to maintain good machining performance and precision. Polishing equipment will produce a lot of dust and other impurities in the working process, and wet dust removal device plays a key role in collecting and processing these impurities.

[0003] However, most of the numerical control machine tool cooling liquid circulating devices and polishing equipment wet dust removal devices on the market have some significant problems. Among them, many devices use single screen filter method. Although this method can play a certain filtering role, it often has the disadvantages of incomplete filtering effect, easy clogging and difficult cleaning. And some devices do not even have effective filtering structure, which leads to the accumulation of impurities in the system during equipment operation, and seriously affects the normal operation of the equipment.

[0004] When single screen filter is used, due to the limitation of its filtering capacity, impurities are easy to block the screen, which makes cleaning work extremely frequent and tedious. Workers have to spend a lot of time and effort to clean the screen, which not only increases labor intensity, but also makes operation very inconvenient. More seriously, when the filter device needs to be cleaned, the equipment often has to be shut down, which directly leads to the interruption of production process. In large-scale production or under high production time requirements, such shutdown will bring great inconvenience to customers, such as delaying product delivery time, affecting the progress of subsequent production plan, etc. At the same time, shutdown will also bring the enterprise considerable economic loss, including reduction of production efficiency, increase of production cost and possible breach of contract risk due to failure to complete orders on time, etc.

[0005] For example, in the high-speed machining process of numerical control machine tool, if the filtering effect of cooling liquid circulating device is poor, it may lead to too many impurities in the cooling liquid, which will affect the cooling effect and service life of the tool, and even may have negative impact on machining precision, resulting in that the machined workpiece does not meet the quality requirements. In the operation of polishing equipment, if the wet dust removal device cannot effectively filter dust and other impurities, it will not only worsen the working environment and threaten the health of operators, but also cause the pollution and damage of internal parts of the equipment, reduce the overall performance and service life of the equipment. If the equipment needs to be shut down frequently due to frequent cleaning of filter device, it will undoubtedly seriously affect the production benefit and market competitiveness of some enterprises with urgent production tasks.

[0006] Therefore, we propose a processing equipment filter device to solve the above problems. Invention content

[0034] Roller 9: in the shape of cylinder grid, is the main part of filtration, realizing filtration and separation of impurities, and residue can be discharged outside through residue discharge channel 8 arranged inside.

[0035] Working principle: when sewage and dirt connected with water curtain cabinet enter the device, variable frequency motor 6 starts to operate under electric drive, and transmits power to reduction gear 5 through coupling 4. Reduction gear 5 adjusts rotating speed, and drives roller 9 to start rotating.

[0036] With the rotation of roller 9, its grid-shaped structure filters and separates sewage and dirt, and intercepts larger garbage and other impurities on the screen of roller 9.

[0037] When certain time or condition is reached, backwash spray head 2 starts to work.
