Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding liquid filtering device for surface grinding machines. Background Art

[0002] Grinding and polishing agents, also known as grinding fluids, are composed of aviation gasoline, kerosene, transformer oil, various vegetable oils, animal oils and hydrocarbons, with a number of additives. They are widely used in the grinding and polishing of superhard materials, cemented carbide and other hard materials for electronic products. They can not only increase the grinding rate, but also quickly dissipate the large amount of heat generated during the grinding process, thereby avoiding burns on the workpiece surface. The grinding fluid needs to be filtered out of iron chips and residues after use, so a filtering device is required.

[0003] The grinding liquid filter device needs to clean the filter element after being used for a period of time. Currently, the machine needs to be shut down to clean the filter element, which will affect the efficiency of grinding liquid filtration and workpiece processing. In addition, it is inconvenient to disassemble and assemble the filter element. Therefore, a grinding liquid filter device for surface grinding machine processing is urgently needed to be developed. Utility Model Content

[0004] In response to the above-mentioned deficiencies in the prior art, the present invention provides a grinding liquid filtering device for surface grinding machines. By alternately cleaning a pair of filter cartridges, while one filter cartridge is being cleaned, the other filter cartridge can be used normally, without delaying the filtering of the grinding liquid and the processing of the workpiece. When disassembling the filter cartridge, it is only necessary to detach the block on the inner wall of the filter cartridge from the groove and then take out the filter cartridge, which is convenient to operate.

[0005] The filter press of the invention is connected with a filter press of the invention, and the filter press of the invention is connected with a filter press of the invention.

[0006] Preferably, a plurality of bolts are provided through the filter cartridge, and a plurality of the clamping blocks are threadedly connected to the plurality of bolts.

[0007] Preferably, a conical liquid guide plate is provided at the bottom of the inner cavity of the box.

[0008] Preferably, a partition is provided on the inner wall of the top of the box body and between the pair of filter cartridges.

[0009] The utility model provides a grinding liquid filtering device for surface grinding machine processing, which has the following beneficial effects:

[0010] 1. The utility model cleans a pair of filter cartridges alternately, so that when one filter cartridge is being cleaned, the other filter cartridge can be used normally, without delaying the filtration of the grinding fluid and the processing of the workpiece. When removing the filter cartridge, it is only necessary to separate the block on the inner wall of the filter cartridge from the groove and then take out the filter cartridge, which is convenient to operate.

[0011] 2. A conical liquid guide plate is provided at the bottom of the inner cavity of the box of the utility model. The conical liquid guide plate guides the filtered grinding liquid into the liquid outlet pipe to prevent the grinding liquid from remaining in the box; a partition is provided on the inner wall of the top of the box and between a pair of filter cartridges. When cleaning one of the filter cartridges, the partition can block the grinding liquid at the falling point to prevent the grinding liquid from splashing onto the operator, making it easier for the operator to operate.
