Embodiment 1

[0064] see figure 1 as well as figure 2 , This embodiment provides a device for filtering and recovering magnetic material processing waste liquid, which can filter the waste liquid generated during the production and processing of magnetic materials and recover the magnetic part therein. Wherein, the filter recovery device includes filter bucket 1, liquid inlet funnel 2, liquid inlet valve 3, partition plate 4, filter assembly, electromagnet 7, crushing assembly, transmission assembly, separation mechanism, sedimentation tank 15, detection assembly and control The device, in this embodiment, may also include a second slide plate 26, an angle adjustment assembly, a collection bucket one 29 and a collection bucket two 30.

[0065] Filter barrel 1 can be placed vertically on the ground, also can be placed directly in other equipment, can also be placed on other processing platforms. Filter bucket 1 can adopt square bucket, also can adopt the bucket body of shape, can also dir...

Embodiment 2

[0084] This embodiment provides a device for filtering and recovering magnetic material processing waste liquid, which adds the control function of the controller on the basis of Embodiment 1. Wherein, when the accumulation amount exceeds the preset accumulation amount, the controller also calculates the difference between the accumulation amount and the preset accumulation amount, and adjusts the expansion and contraction of the expansion member 6 with reference to a preset difference-expansion amount comparison table. quantity. There is a one-to-one data correspondence between the difference value and the stretch amount in the difference value-stretch amount comparison table.

[0085] Certainly, in some embodiments, the controller is also used to judge whether the corresponding relationship between the amount of expansion and contraction of the telescopic member 6 and the difference satisfies the data corresponding relationship, and then judge whether the accumulation amount...

Embodiment 3

[0088] see image 3 , This embodiment provides a filter and recovery device for magnetic material processing waste liquid, which is similar to the filter and recovery device for magnetic material processing waste liquid in Embodiment 1, except that the structure of the detection mechanism is different. In this embodiment, the detection mechanism includes a second load cell 23 , a sliding cover 24 and a second photoelectric sensor 25 .

[0089] The number of the second load cell 23 and the sliding cover 24 is at least three, and there is a one-to-one correspondence between the second load cell 23 , the sliding cover 24 and the filtering space. Each sliding cover 24 is installed in the corresponding filtering space, and slides along the gravitational direction of the magnetic waste. Each group of electromagnets 7 is installed in the corresponding sliding cover 24 , and the generated magnetic field can attract the magnetic waste in the corresponding filtering space on the corres...

Abstract

The invention discloses a filtering recovery device for magnetic material processing waste liquor and a filtering recovery method therefor. The device comprises a filtering barrel, a liquor feeding funnel, a liquor feeding valve, a partition plate, filtering assemblies, an electromagnet, conveying assemblies, a separating mechanism, a deposition tank, detecting assemblies and a controller. Each filtering assembly comprises a filter screen and a telescopic member, and each conveying assembly comprises a slide plate I, a baffle and a driving member. The detecting assemblies are used for detecting accumulation volume of wastes on each filter screen and adsorption capacity of magnetic wastes in each filtering space. The controller is used for driving corresponding telescopic members to retreatwhen the accumulation volume exceeds preset accumulation volume so as to increase degree of inclination of the filter screens; and when the adsorption capacity exceeds preset accumulation volume, a liquid outlet is closed firstly, then, a discharging opening is closed, a knockout through hole is opened, and finally, the electromagnet is shut off. According to the device and the method, the recycling rate of the magnetic material processing waste liquor can be increased, the cleaning of the waste liquor is facilitated, and environmental pollution caused by direct discharge of the waste liquoris avoided.

Description

technical field [0001] The invention relates to a filter recovery device in the technical field of waste material recovery, in particular to a filter recovery device for magnetic material processing waste liquid. Background technique [0002] Materials that respond in some way to a magnetic field are called magnetic materials. According to the strength of the magnetic properties of the substances in the external magnetic field, they can be divided into diamagnetic substances, paramagnetic substances, ferromagnetic substances, antiferromagnetic substances and ferrimagnetic substances. Most magnetic materials are diamagnetic or paramagnetic, which means they respond weakly to external magnetic fields. Ferromagnetic substances and ferrimagnetic substances are ferromagnetic substances, and the so-called magnetic materials refer to ferromagnetic materials. [0003] At present, during the processing of magnetic materials, a large amount of waste water will be produced, and at th...
