Abstract
The utility model relates to a magnetic absorption device, in particular to a shell of a magnetic rod. A shell of a magnetic rod is disclosed, which wraps a permanent magnet rod, and the outer surface of the shell is provided with a plurality of concave grooves. A plurality of fine concave grooves are arranged on the outer surface of the shell of the magnetic rod, and the absorbed metal powder and chips can be embedded in the concave grooves, and not be washed away by plastic particles; therefore, the magnetic absorption device can absorb the metal power and chips which are mixed in plastic particles more stably, can improve magnetic absorbing efficiency and production efficiency and reduce energy consumption at the same time.
Description
Technical field
The utility model relates to a kind of magnetic force adsorbent equipment, relates in particular to a kind of shell of magnetic bar.
Background technology
In the process of plastic pellet production and processing because the wearing and tearing of equipment, special production technology, numerous factors such as human factor of being difficult to expect cause existing the generation of some metal dusts, fragment in the material grain.This quality control to product has brought huge threat, and uses and process and buried very big hidden danger in the operation in the later stage of product.Therefore, we have very important operation in the process of plastic pellet production with processing: the metal dust that is mingled with in particle with the shell of magnetic bar, fragment carry out adsorbing separation, with popular words, be exactly magnetic.
At present widely used in the industry is exactly to utilize the shell of permanent magnet magnetic force rod that the metal iron filings in the plastic pellet are adsorbed.
The shell of magnetic bar commonly used is made up of permanent magnet bar and the smooth shell that is enclosed within the permanent magnet bar outside.In use, the shell of several magnetic bars is set in the plastic pellet passage usually, when plastic pellet passes through the shell of magnetic bar, thereby the barred body surface contacts the metal dust adsorption effect that produces being mingled with in the plastic pellet with plastic pellet.Yet, because a large amount of plastic pellets have certain initial velocity when the shell by magnetic bar, when expecting the shell of a magnetic bar that passes through surface smoothing, metal dust, fragment that plastic pellet is easy to the shell of magnetic bar has been adsorbed onto wash away, and metal dust mixes in the middle of plastic pellet once more.Thereby, reduced the effect of crossing magnetic, in order to reach certain removal effect, then to increase the number of times and the time of magnetic, cause the increase of production efficiency reduction and energy consumption.
The utility model content
Technical problem to be solved of the present utility model is: the shell that a kind of novel magnetic bar is provided, the outer surface of this shell is provided with some fine recesses, more stably add assorted metal dust and fragment in the adsorption plastic particle, metal dust, the fragment of avoiding plastic pellet easily the shell of magnetic bar to be adsorbed onto wash away, to overcome the above-mentioned defective that prior art exists.
A kind of shell of magnetic bar, it is rolled in the permanent magnet bar outside, and the outer surface of described shell is provided with some grooves.
Described groove is semicircle or strip slot or irregular pit.
Described groove evenly distributes or uneven distribution.
The shell of described magnetic bar adopts permeability magnetic material to make.
Described permeability magnetic material is iron or ferroalloy or nickel or silicon steel or permalloy or ferrite.
The shell of a kind of magnetic bar of the utility model, adopt outer surface to be provided with some fine recesses, more stably add assorted metal dust and fragment in the adsorption plastic particle, effectively having reduced the metal dust that the magnetic bar shell is adsorbed onto, fragment mixes in plastic pellet once more, therefore effectively improved and crossed the magnetic effect, improve production efficiency, reduced energy consumption simultaneously.
Description of drawings
Fig. 1 is the structural representation (cutaway view) of the shell of the utility model magnetic bar
Fig. 2 is the right view of Fig. 1.
Among the figure: 1 permanent magnet bar, 2 shells, 3 grooves.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, a kind of shell 2 of magnetic bar is cylindric, and it is rolled in the permanent magnet bar outside, and its outer surface is provided with some fine recesses 3.Described groove 3 is semicircular pits, is evenly distributed on the outer surface of shell 2.Described shell 2 adopts permeability magnetic material.Metal dust and fragment that the magnetic of described permanent magnet bar 1 can see through in 2 pairs of plastic pellets of shell carry out adsorbing separation.
In addition, described groove 3 can also be strip slot or irregular pit.
Described groove 3 can evenly distribute on the outer surface of shell, also can uneven distribution.
The shell 1 of described magnetic bar can be to be made by permeability magnetic materials such as iron or ferroalloy or nickel or silicon steel or permalloy or ferrites.
The utility model is work like this:
Several magnetic bars are set in the plastic pellet passage.Because the material of novel housing 2 is permeability magnetic materials, and the magnetic of permanent magnet bar 2 can be adsorbed the metal ingredient in the plastic pellet through novel housing, so when plastic pellet passed through the shell 3 of magnetic bar, metal dust that is mingled with in the plastic pellet that the barred body surface will contact with it and fragment produced suction-operated.Because the outer surface of shell is provided with a lot of tiny grooves, therefore, tiny metal dust will embed and be difficult in the groove being washed away by plastic pellet again.
When clearing up, only need permanent magnet bar is extracted out in shell, because shell does not have magnetic originally, so the iron filings on the cleaning shell are easy especially.
The outer surface of the shell of the utility model magnetic bar is provided with some fine recesses, more stably adds assorted metal dust and fragment in the adsorption plastic particle, effectively reduces metal dust and the fragment that the magnetic bar shell is adsorbed onto and mixes in plastic pellet once more.Therefore, improve the magnetic effect excessively of plastic pellet, effectively improved production efficiency, reduced energy consumption simultaneously.
The above embodiment only is the utility model preferred embodiment, is not to be used for limiting application range of the present utility model.Therefore, all simple transformation according to structure described in the utility model, shape all should fall within the utility model protection range.
