Description of the embodiments

Embodiments of the present invention will be described in more detail below with reference to the drawings and reference numerals, so that those skilled in the art can practice the present invention after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Examples

The invention provides a film salvage water filtering device as shown in fig. 1-2, which comprises a chute 20, a bracket, a first rotating shaft 30 and a second rotating shaft 40, wherein the chute 20 is arranged on one side of a cleaning tank 10 and is communicated with the cleaning tank 10, the bracket is arranged on two sides of the chute 20, the first rotating shaft 30 and the second rotating shaft 40 are rotatably connected with the bracket, the chute 20 extends obliquely upwards, two ends of the first rotating shaft 30 are respectively provided with a first chain wheel 31, two ends of the second rotating shaft 40 are respectively provided with a second chain wheel 41, the first chain wheels 31 and the second chain wheels 41 on the same side are in transmission connection through chains 50, a plurality of material sweeping rakes 60 are further arranged between the two chains 50, and each material sweeping rake 60 comprises a connecting plate 61 connected between the two chains 50 and a plurality of rakes 62 sequentially arranged along the length direction of the connecting plate 61.

The cleaning pool 10 is used for cleaning membrane materials, storing water in the cleaning pool 10, and then immersing the membrane materials into water for cleaning to remove impurities such as sediment; the prior art cleaning tank 10 is also provided with a plurality of drums which are provided with a plurality of levers extending into the water surface along the axial direction thereof for pushing the membrane material to the chute 20. The first rotating shaft 30 and the second rotating shaft 40 rotate to drive the chain 50 and the sweeping rakes 60 arranged on the chain to repeatedly move, the plurality of sweeping rakes 60 continuously push the membrane materials at the joint of the chute 20 and the cleaning tank 10 onto the chute 20, the membrane materials are pushed to continuously rise along the chute 20, and finally the membrane materials slide out from the top of the chute 20 to finish salvaging.

Compared with the prior art, the sweeping rake 60 has a comb structure, the central connecting line L of the first rotating shaft 30 and the second rotating shaft 40 can be parallel to the bottom surface of the chute 20, and the salvaging process of the film material can be simplified to uniform linear motion of the film material upwards along the bottom surface of the chute 20. In the process, the film material is not easy to wind on the harrow nails 62; the gaps between the plurality of rakes 62 and between the rakes 62 and the chute 20 are relatively wide and relatively long, and the entrained moisture can more easily flow from the gaps back into the wash tank along the chute 20 during the rising of the film stock along the chute 20, completing dewatering. The water content in the membrane materials can be controlled by controlling the gradient of the chute 20 and the moving speed of the sweeping rake 60, and when the included angle between the bottom surface of the chute 20 and the horizontal plane is more than or equal to 30 degrees and the moving speed of the sweeping rake 60 is 0.2 m/s, the dewatering effect is good, and the water content of the salvaged membrane materials can be reduced to below 20%.

Meanwhile, the harrow nails 62 have a certain length, so that the harrow nails 62 can only extend into water to complete salvaging, and the first rotating shaft and the second rotating shaft are arranged above the water surface, so that the phenomenon of machine clamping caused by winding the film materials on the rotating shafts can be effectively prevented; specifically, in the present embodiment, the first rotating shaft 30 and the second rotating shaft 40 are both higher than the wall of the washing tank 10.

Further, the shortest vertical distance H1 between the rake pin 62 and the bottom of the cleaning tank 10 is 1/3-2/3 of the height of the wall of the cleaning tank 10. Different membrane materials have density differences, and after cleaning, the membrane materials with different densities have different distribution heights in water, so the membrane materials after cleaning can be classified by controlling the depth of the rake nails 62 extending into the water.

Preferably, the device further comprises a driving device in transmission connection with the first rotating shaft 30 or the second rotating shaft 40, the driving device is a variable frequency motor, and the rotating speeds of the first rotating shaft and the second rotating shaft are controlled through the variable frequency motor, so that the moving speed of the sweeping rake 60 is controlled, and the fishing speed is adjusted.

Preferably, the chute 20 is further provided with a discharge hopper 21 for collecting the salvaged film materials to the next operation.

Examples

The invention provides a thin film salvage water filtering device as shown in figure 3. Unlike in embodiment 1, an included angle is formed between the central line L of the first rotating shaft 30 and the second rotating shaft 40 and the bottom surface of the chute 20, the included angle may be 1-5 °, and the vertical distance H1 from the central axis of the first rotating shaft 30 to the bottom surface of the chute 20 is smaller than the vertical distance H2 from the central axis of the second rotating shaft 40 to the bottom surface of the chute 20.

When the sweeping rake 60 is positioned at the bottom of the chute 20, the gap between the tail end of the rake nail 62 and the chute 20 is smaller, and most of the film material floating in the chute can be basically fished out of the water; in the process that the sweeping rake 60 ascends from the bottom of the chute 20 to the top, the gap between the tail end of the rake nail 62 and the chute 20 is larger and larger, the expansion of the gap is beneficial to water to flow back into the cleaning pool, meanwhile, the contact surface of the rake nail 62 and the film material gradually moves towards the upper part of the film material, the pushing force for the film material is smaller and smaller, the rising speed of the film material is gradually slowed down until the film material stops at a certain position of the chute 20, water is more sufficient to flow back into the cleaning pool, the next sweeping rake pushes the next batch of film material to the position, extrusion is generated between the front batch of film material and the rear batch of film material, partial water clamped by the film material is extruded, and the water content of the film material is further reduced; the process is repeated by a plurality of sweeping rakes, and the membrane material is extruded from bottom to top and pushed until climbing to the top of the chute and sliding out into the discharge hopper 21.

The foregoing is a description of one or more embodiments of the invention, which are specific and detailed, but are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
