Description

A scraper chip removal filter using wedge wire drum filter

technical field

The invention is a scraper chip removal filter which uses a wedge wire drum to filter. The invention is mainly used in the field of machine tool processing for chip discharge and cutting fluid filtration.

Background technique

In the field of machine tool processing, especially in the field of wet machine tool processing, the main tasks of chip and cutting fluid treatment are: (1) to discharge the chip from the machine tool, (2) to separate the chip from the cutting fluid, that is, to treat the cutting fluid to filter. Various forms of chip removal devices are often used to discharge chips from the machine tool, such as chain conveyors, scraper conveyors, magnetic conveyors, etc. Filtration of cutting fluid is generally achieved through barriers, filter screens, magnetic separators, paper tape filters, eddy current separators, linear filters, etc. configured on the water tank. Generally, the cutting fluid storage chamber before filtering is called the clean fluid tank. , The filtered cutting fluid storage cavity is called the dirty fluid tank.

The chip removal device generally has a certain filtering function, and the improvement of the filtration accuracy of the chip removal device is very beneficial to the reduction of the configuration of the water tank and the reduction of the cleaning frequency of the dirty liquid tank of the water tank. The filter devices used in the chip removal device can be divided into the following two categories according to the principle:

1. Use large slit plate and large mesh orifice plate to filter. For example, the chain plate chip conveyor filters larger chips through the gap of the conveyor chain plate itself, and the scraper chip conveyor filters larger chips through the mesh. Due to the need to consider the flow rate and the fact that the mesh or gap will not be blocked when the chip conveyor is required to use the filter material, the filter material mesh or gap used is large, resulting in low filtration accuracy. Therefore, there will be a lot of chips in the dirty liquid tank of the water tank of the machine tool, especially a large amount of chips are deposited in the water tank near the outlet of the chip conveyor, which requires frequent manual cleaning.

2. Use recoil drum filter. It adopts slit plate, polyurethane filter screen and stainless steel filter screen to make a cylindrical shape for filtration. The two sides of the cylinder are sealed, the outside is dirty liquid, and the inside is clean liquid. A nozzle is set inside the filter material cylinder to continuously flush the filter material to prevent the filter material from clogging. This method improves the filtration accuracy to a certain extent, and can meet the needs of small flow conditions. However, the following problems still exist: (1) the structure is complex, especially the dynamic sealing structure at both ends and the backwashing structure. (2) While backwashing the filter material, a large amount of filtered net liquid is consumed. (3) The filtration flow rate is small, and part of the backwashing filter material needs to be consumed, which makes it unsuitable for working conditions with high flow requirements.

A scraper chip removal filter using a wedge wire drum filter described in the present invention can effectively make up for the above shortcomings of the traditional chip removal device.
