Description

Technical Field

[0001] The utility model relates to the technical field of chip conveyors, in particular to a combined filter device of a recoil roller and a vertical paper belt. Background Art

[0002] During the machining process of machine tools, high temperatures are often generated. In order to cool and lubricate the tools and workpieces, chip fluid is often added during the machining process to play a cooling and protective role. In order to avoid resource waste and environmental pollution, the chip fluid usually needs to be recycled. However, impurities such as chips generated during the machining process will mix with the chip fluid. When it is reused, the chips in the coolant need to be filtered and discharged.

[0003] The recoil drum chip conveyor is a commonly used chip removal equipment for machine tools. The chips and coolant generated during the machining process of the machine tool are discharged from the chip removal port of the machine tool into the recoil drum scraper chip conveyor. The chips are transported to the chip removal port through the scraper and fall into the chip collection car. The drum is designed with a backwashing function from the inside to the outside to keep the filter clean. The coolant is finely filtered by the polygonal drum and then purified by the water channel and filter in the water tank. The purified coolant can be recycled and reused by the machine tool. The existing recoil drum chip conveyor is often placed on the ground together with the water tank, occupying a large ground space. When the chip liquid filtered by the drum in the water tank is transported, water pumps and other equipment are often required for transportation, resulting in increased energy consumption and costs. The installation position of the water pump is often located on the top or side of the water tank, which is difficult to insert into the bottom of the water tank. This results in fine impurities remaining at the bottom of the water tank, and the water tank needs to be cleaned regularly.

[0004] The vertical paper belt filter is a device that uses filter cloth or filter paper to filter impurities in the cutting fluid or cutting oil. The vertical paper belt filter is mainly composed of the following parts: a housing, a mesh chain, a mesh chain drive structure and a paper pressing plate arranged in the housing. A paper outlet and a paper inlet are respectively provided on both sides of the housing. The mesh chain drive structure includes a drive shaft respectively arranged between the paper pressing plate and the paper outlet and a driven shaft respectively arranged between the paper pressing plate and the paper inlet. A limiting roller is respectively provided at the lower part of the drive shaft and the driven shaft. The paper belt filter can fully filter out various types of metal and non-metallic fine impurities in the coolant, and is particularly suitable for various types of grinding machines, honing machines and other finishing machine tools. When the dirty liquid falls on the filter cloth, fine chips and impurities are adsorbed on the filter cloth, and they themselves become a filter layer to participate in the filtration, which increases the filtering effect of the filter cloth. Since the filter cloth works on an arc surface, it not only increases the filtering area, but also reduces the floor space. Utility Model Content

[0005] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a recoil drum and vertical paper belt combined filtering device.

[0006] To achieve the above objectives, the technical solutions adopted are:

[0016] Furthermore, a water pump is provided on the clean liquid water tank, and the water pump is connected to the reflux pipeline and the backwash pipeline.

[0021] Furthermore, the chip conveyor housing includes a horizontal housing and an inclined housing, the auxiliary water tank includes a housing, and the bottom of the chip conveyor horizontal housing is not lower than the bottom of the auxiliary water tank housing.
