Abstract

The utility model discloses a magnetic filter, which comprises a casing, wherein an end cover is arranged above the casing, a liquid inlet, a liquid outlet and a deflation valve are arranged on the end cover, a magnetic filter core is arranged in the casing, the upper end of the filter core is connected with the end cover, the bottom of the filter core is provided with a filter core liquid inlet, and a filter cavity is formed between the filter core and the casing. The utility model is characterized in that the outer wall of the filter core is a thin-wall outer tube, and the inner wall is a thick-wall inner tube. Compared with the prior art, the utility model has the advantages that a strong magnetic field exists outside the filter core, the absorption capability is greatly enhanced, the filter effect is good, the efficiency is high, flow passages inside the filter core are smooth, the abrasion rate of each component of the filter core is low, the service life of the filter is long, no consumptive materials are adopted, the production efficiency is obviously improved, and the magnetic filter is applicable to various mechanical processing industries.

Description

Magnetic filter

Technical field

The utility model relates to a kind of magnetic filter, is applicable to the dirty liquid in the mechanical processing industry is carried out filtration treatment.

Background technology

In field of machining; the industrial wastewater that produces need be handled with magnetic filter; but there are a lot of shortcomings in existing magnetic filter; for example: do not have to form very strong field of magnetic forece around the magnetic cylinder; cause the assorted bits in the dirty liquid can not be well attached to cartridge surface, filter not thoroughly, residual impurity be more in the filtrate; filtrate has some setbacks at the magnetic cylinder internal circulation, clogging etc. occurs through regular meeting.

Summary of the invention

The purpose of this utility model is to improve the weak point in the prior art, and a kind of novel structure is provided, and the magnetic cylinder absorption affinity is strong, and runner is smooth and easy, is difficult for stopping up the magnetic filter of impurity.

The technical solution of the utility model is: a kind of magnetic filter, it has housing, on housing, be provided with end cap, liquid inlet, liquid outlet and vent valve are arranged on the end cap, in housing, be provided with the magnetic filter core, the upper end of filter core is connected with end cap, the filter core bottom is provided with the filter core liquid inlet, forms between filter core and the housing and filters cavity, and characteristics are, the outer wall of filter core is the thin-walled urceolus, and inwall is the heavy wall inner core.

The inside and outside tube of the filter core of existing magnetic filter is stainless steel and makes, and inner tube wall is very thin, therefore causes the filter core inner magnet field of force big, and the filter core periphery does not have the very strong field of magnetic forece of formation and influence its adsorption capacity; Comparatively speaking, because filter core inner tube wall of the present utility model has adopted the thickness bucket wall structure, the inside magnetic line of force is blocked and distributes outwardly, make the powerful field of magnetic forece of the outside formation of filter core, adsorption capacity strengthens greatly, good filtration effect, the efficient height, the filter core inner flow passage is smooth and easy, and the wear rate of each parts of filter core is low, except timely cleaning impurity, need not to carry out component maintenance, the filter long service life, no material consumption, production efficiency obviously improves.

Below in conjunction with drawings and Examples the utility model is done at length and to be explained.

The explanation of accompanying drawing drawing:

1 filter core, 2 housings, 3 liquid inlets, 4 vent valves, 5 end caps, 6 liquid outlets, 7 filter core liquid inlets, 8 thin-walled urceolus, 9 heavy wall inner cores, 10 magnetic patch.

The specific embodiment

Referring to Fig. 1, the utlity model has barrel-type casing 2, on housing 2, be provided with end cap 5, liquid inlet 3, liquid outlet 6 and vent valve 4 are arranged on the end cap 5, the lower end of end cap 5 and magnetic filter core 1 link together, filter core 1 bottom is provided with filter core liquid inlet 7, forms between filter core 1 and the housing 2 and filters cavity, and the outer wall of filter core 1 is a thin-walled urceolus 8, useful stainless steel is made, inwall is a heavy wall inner core 9, can adopt thicker iron pipe to make, and the ferromagnetism magnetic patch 10 of neodymium iron boron material is housed between inner core and the urceolus.

Operation principle: have the liquid inlet 3 inflow filter cavitys of the liquid of impurity from filter, outer wall along filter core 1 flows downward, in this process, under the ferromagnetism suction-operated of filter core 1, impurity is adsorbed on the filter core outer wall, suction magnetic impurity in the liquid is removed from liquid, and clean filtrate enters filter core 1 inside from the filter core liquid inlet 7 of bottom, upwards flows to the liquid outlet 6 of end cap 5 via the recovery path of filter core central authorities then and discharges.

In order not stop up runner, magnetic patch 10 in this product filter core 1 can be according to the flux loop setting, be that corresponding magnetic patch 10 is opposite sex setting on the circumference, as shown in Figure 3, like this magnetic line of force be distributed as the rule laterally circular, the impurity that is adsorbed can be according to the geometry accumulation that is distributed in filter core outer wall formation rule of flux loop, and liquid always can freely flow downward along the space in the runner, makes filter blocked never.
