Description

A kind of iron core and electric magnetic iron remover

Technical field

The utility model belongs to iron core and electric magnetic iron remover equipment technical field, and in particular to is situated between to a kind of with water to be cooling The iron core and electric magnetic iron remover of matter.

Background technique

The presence of iron content in the materials such as coal, ceramics not only influences product quality, but also may lead in the process of reproduction Safety accident is caused, removes the iron tramp in such material, iron remover has become the first choice equipment.Currently, iron remover is in metallurgy, mine Exist in numerous industries such as choosing, coal choosing, power plant, building materials, chemical industry and food processing and be widely applied, in emerging garbage disposal industry In also performer key player.

According to the excitation mode of iron remover, it is generally classified as electric magnetic iron remover and permanent-magnetic iron expeller.The magnetic of permanent magnetism deironing Field intensity is influenced by the material property of magnetic patch, and rare-earth Nd-Fe-B magnetic patch material cost is high, and its rare earth material is non-renewable makes The sustainable development for obtaining permanent-magnetic iron expeller is limited.Electric magnetic iron remover is to use the power on the powerful magnetic force of generation to be mingled in material In iron tramp pick up, achieve the purpose that remove iron tramp automatically.The magnetic field strength of electric magnetic iron remover can according to coil turn and Size of current control, but since in the iron remover course of work, coil can continually generate heat, and the raising of coil temperature is not only The magnetic field strength of its generation is reduced, and the insulating properties of electromagnetic coil is also by test, if the heat dissipation of coil is obstructed, even It can direct burning apparatus.

Currently, electric magnetic iron remover generally uses natural cooling, the low efficiency of natural cooling, and it is air-cooled, oil is cold etc. generally needs Add outside standby, it is widely applied cannot always in production in these deficiencies.Authorization Notice No. CN202199416U's is special It mentions after coil inside and outside shell sealing, to inject water between inside and outside shell in benefit and be allowed to cool, it is clear that this type of cooling is invisible In again increase the size of iron remover itself, be unable to get application in the occasion of limited space, and the existing type of cooling is cold But effect has much room for improvement.

Utility model content

Problem to be solved in the utility model is to will increase iron remover itself for cooling device in existing electric magnetic iron remover The problem of size, provides a kind of iron core and electric magnetic iron remover.

In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of iron core opens up in the iron core There is the water stream channel for making iron core cool down for being passed through water flow, water inlet, the water outlet of the water stream channel are provided with iron core Top, the water stream channel include the first passage, second channel, third channel being provided in iron core, the bottom end of the iron core It opens up fluted, sealing plate is installed on the groove, form the first passage between the groove and sealing plate, described Two channels, third channel are connected to by the first passage, and the water inlet, water outlet are respectively the second channel, third Opening of the channel on the top of iron core.

In the utility model, without changing core body structure and installation method, it is only necessary to be opened up on original iron core top At least two through-holes correspond respectively to second channel, third channel, so that second channel, third channel are formed on iron core top Water inlet, water outlet, and groove is opened up in the bottom end of iron core, each through-hole is connected to groove, can be connected to water stream channel, recessed Sealing plate is installed on slot, mandrel bottom can be sealed.First passage is formed between groove and sealing plate.Lead in the utility model Cross simply open up through-hole, open up groove, installation sealing plate can conveniently obtain it is being arranged in iron core, make for being passed through water flow The water stream channel of iron core cooling.The utility model is without redesigning the structure of iron core, being re-worked, it is only necessary to existing Iron core, which carries out simple working process, can be realized water stream channel, to realize to the cooling function of iron core, avoid core structure It is wasted caused by redesign.Moreover, in the utility model realize cooling effect water stream channel no need to increase plant bulks.This The water stream channel of the core interior of sample setting is also convenient for processing.

Further, the second channel, third channel are arranged on the axial direction of iron core.
