Description

TECHNICAL FIELD

[0002] Industrial water saving technology refers to a technology capable of improving industrial water efficiency and benefits, reducing water loss and replacing conventional water resources. Vigorously developing and popularizing industrial water recycling technology and improving water recycling rate are the primary approach of industrial water saving.

[0003] At present, in the field of industrial processing cutting, such as stone cutting and metal plate cutting, water cutting is gradually becoming the mainstream cutting method in the field of industrial cutting technology. Water cutting, also known as water jet cutting, is a machine that cuts by using high-pressure water flow. It has the advantages of easy operation and high yield rate. However, it also has the disadvantage of requiring a large amount of water. For enterprises, energy saving and cost reduction are the main theme of enterprise development. Therefore, under the concept of industrial water saving, recycling of industrial cutting wastewater is a feasible approach.

[0004] In the cutting wastewater recycling treatment process, the first step is to filter the industrial cutting wastewater, i.e., pre-treatment. Taking stone cutting as an example, most of the existing pre-treatment filtering devices use horizontally arranged filter plates for filtering. Although they can play a filtering role, the filter plates are fixedly arranged, and the trapped impurities are not easy to clean, which is relatively time-consuming and labor-intensive. For example, the wastewater filtering mechanism of a stone cutting machine disclosed in the patent with the authorization announcement number CN210170936U has a trough arranged in the middle of the cutting table, which is connected to the upper and lower parts. A filter plate is arranged in the lower part of the trough, and connecting plates are fixedly arranged at the left and right ends of the filter plate. The connecting plates are fixedly connected to the cutting table through bolts, and a filter box is arranged directly below the filter plate.

The thrust plate is in U shape; The right side of the outer box body is provided with a collection box; an inclined flow guide plate is further connected in the outer box body, the flow guide plate is arranged below the support seat, one end of the flow guide plate penetrates out of the right side of the outer box body and extends to the top of the collection box; The steps for cleaning the filter residue trapped on the filter screen are as follows: S1: control the sliding assembly to move the inner box out of the outer box as a whole; Start the electric telescopic rod, which pushes the thrust plate to move, and the thrust plate drives the side plate and the support seat to slide together with the inner box; the sliding column moves horizontally to the left along the first horizontal segment of the track groove; when the sliding column enters the oblique connecting segment, the driving link will swing under the guidance of the oblique connecting segment, thereby driving the support seat and the driven link to swing, so that the support seat and the inner box are lifted and pass out of the outer box; when the sliding column enters the second horizontal segment, the support seat can no longer be lifted but only slide; the track route of the support seat is "sliding-sliding while lifting-sliding", and when the inner box moves to the appropriate position, the electric telescopic rod is turned off; S2: control the turnover assembly to turn over the filter screen to realize the dumping of the filter residue; Drive the rotating shaft to rotate, which drives the swing arm to rotate; the swing arm will drive the connecting rod to move when rotating, and the connecting rod will in turn drive the second guide rod to move; the second guide rod slides upward along the vertical guide groove; at this time, the first guide rod, the turnover bracket and the filter screen are all moved upward as a whole under the upward pushing force of the second guide rod; when the first guide rod moves to the top end of the vertical guide groove, the first guide rod can no longer continue to move upward; at this time, taking the first guide rod as the rotation point, the second guide rod slides from the vertical guide groove into the arc-shaped guide groove and slides along the arc-shaped guide groove; the turnover bracket drives the filter screen to complete the turnover, and the trapped filter residue falls from the filter screen, realizing cleaning.
