The device comprises a cavity, wherein a charging port and a discharging port are arranged at two ends of the cavity respectively, at least one partition board is arranged inside the cavity, the inside of the cavity is divided into at least two flow passages by partition boards, magnetic bars are arranged inside flow passages, and buffer portions are arranged between the charging port and flow passages and between the discharging port and flow passages respectively. According to the iron-removing filtering device, magnetic bars are arranged inside flow passages, iron particles in slurry can be adsorbed onto magnetic bars, and the filtered slurry flows out of the discharging port of the cavity, so that iron particles in the slurry can be removed effectively, the purity of the slurry of lithium ion batteries is improved, and the performance of the slurry of lithium ion batteries is improved.
Description
Technical field
The utility model relates to the deironing filter that filters the iron filings in the slurry in a kind of lithium ion battery cell production process.
Background technology
In the battery core production process, because a variety of causes causes supplied materials, contain part iron particle in the semi-finished product, cause the battery core self discharge excessive, had a strong impact on the performance of battery core, and the iron filings that produce in the pulping process main source that is one of them, so remove iron filings very important just in the slurry.
The electromagnetic field that at present main electricity consumption magnetic bar produces is removed the iron filings in the slurry, although this method can reach the purpose of absorption, but the electromagnetic force rod only forms a large magnetic field, magnetic force concentrates on the two ends of electromagnetic force rod, cause the magnetic force skewness, affect adsorption effect, electromagnetic force rod caloric value in use is larger in addition, and can cause very high electric energy loss.
And for existing permanent-magnet iron removing device, because the design that do not have quite reasonable cavity and bar magnet to arrange, cause very small iron filings to be adsorbed and drain in the subsequent handling and go.
The utility model content
The purpose of this utility model is, the purpose of this utility model is, a kind of deironing filter that can improve the external iron filings of introducing in the whipping process is provided, and solves emphatically the problem that molecule can't be adsorbed.
The technical solution of the utility model is, a kind of deironing filter, comprise cavity, the cavity two ends are respectively arranged with charging aperture and discharging opening, be provided with at least one dividing plate in the cavity, described dividing plate is that non-close magnetic material makes, and described dividing plate is divided at least two runners with inside cavity, is provided with magnetic bar in the runner.Slurry enters from the cavity charging aperture, and the iron filings that the passage in transit magnetic bar is tiny are attracted on the magnetic bar, and this design can be adsorbed the iron particle about 10 microns in the slurry.
As the further improvement of utility model, between this charging aperture and the runner, be respectively equipped with buffer part between discharging opening and the runner.Buffer part has played good cushioning effect, can make the slurry runner of flowing through slowly, makes de-ferrous effect better.
As the further improvement of utility model, leave the gap between this two adjacent magnetic bar.
As the further improvement of utility model, this magnetic bar is arranged in the runner in up and down dislocation mode.Putting of magnetic bar is not along straight line in each passage, first magnetic bar abuts against lower wall surface, second magnetic bar is close to upper wall surface, the iron filings that prevent that like this can very large limit are flushed away, such setting, can increase the contact surface area of magnetic bar, thereby can make de-ferrous effect better.
As the further improvement of utility model, this each runner setting has two magnetic bars at least.
As the further improvement of utility model, the width of this runner is greater than the magnetic bar diameter.
As the further improvement of utility model, this cavity is cuboid, and eight drift angles of cavity are for leading fillet or the angle of chamfer.Can prevent that like this phenomenon of piling up from appearring in slurry in the position, angle.
The beneficial effects of the utility model are, by constructing a kind of deironing filter that is provided with magnetic bar at runner, iron particle in the slurry will be attracted on the magnetic bar, slurry after filtering flows out from the cavity discharging opening, can effectively remove the iron particle in the slurry, improve the purity of pulp of lithium ion battery, improve the performance of improving pulp of lithium ion battery.
Description of drawings
Fig. 1 is top view of the present utility model.
Fig. 2 is three-dimensional structure diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further specified.
Shown in Fig. 1,2, a kind of deironing filter comprises cavity 1, these cavity 1 two ends are respectively arranged with charging aperture 11 and discharging opening 12, be provided with at least one dividing plate 31 in the cavity 1, dividing plate 31 is divided at least two runners 3 with cavity 1 inside, is provided with magnetic bar 32 in the runner 3.Slurry enters from cavity 1 charging aperture 11, and passage in transit magnetic bar 32 tiny iron filings are attracted on the magnetic bar 32, and this design can be adsorbed the iron particle about 10 microns in the slurry.
Be respectively arranged with buffer part 2 between charging aperture 11 and the runner 3 and between discharging opening 12 and the runner 3.Buffer part 2 has played good cushioning effect, can make the slurry runner of flowing through slowly, makes de-ferrous effect better.
Two adjacent magnetic bars 32 are provided with the gap.
Every runner 3 arranges and has two magnetic bars 32 at least.
The width of runner 3 is greater than magnetic bar 32 diameters.
Slurry enters with the charging aperture 11 of certain flow velocity from cavity 1, by buffer part 2, then enter respectively different passage 3, every one slurry was all wanted magnetic bar 32, iron particle in the slurry will be attracted on the magnetic bar 32, slurry after filtering flows out from cavity 1 discharging opening 12 by buffer part 2, enters next process.This filter needs periodic cleaning, in order to avoid the too much iron particle of absorption can affect follow-up adsorption effect on the magnetic bar.
The utility model can be removed the iron particle in the slurry effectively, is to arrange by rational magnetic bar 32, reduces local velocity, makes magnetic field force occupy advantage in the competition of power and realize pulling with fluid.The utility model can be widely used in improving the purity of pulp of lithium ion battery, but be not limited to the pulp of lithium ion battery iron powder and remove technique, for knowing those skilled in the art, the utility model is equally applicable to other production industry that need to guarantee the slurry iron content and technical fields.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
