Abstract

The utility model discloses a magnetic filter frame for moire filtering machine of the zinc hydrometallurgy devices. The bracket, the polymerizer, the clamping plate, the rubber tube connected with the vacuum system, the suspension ring, the wooden plug, and the U-shaped tube in the filter frame of the moire filtering machine existing in the prior art are kept unchanged. The bamboo folding mat or called bamboo splint mat with low grade and easy consumption is canceled, the bamboo folding mat or called bamboo splint mat is replaced with the acid-resistant grid-shaped baffle fence, and the hollow tube with round-shaped or square-shaped cross section is adopted to make into a fence strip. Magnetic material such as a magnet bar, an electromagnet core, or a nd-fe-b magnet is arranged in the fence strip, and a magnetic filter frame is formed.

Description

Magnetic filter frame

The utility model relates to the magnetic force filter frame of Moor's filter in a kind of zinc hydrometallurgy equipment

Though in the existing zinc hydrometallurgy Moor's filter of separating liquid and solid have filter area greatly, simple structure, convenient operating maintenance, characteristics that treating capacity is big, but its filter effect still is the weak link that realizes slag balance in slag balance, volumetric balance, the metal balance balance of finance, credits and materials in modern zinc metallurgy industry, the factory that has makes production procedure in order to adopt the way of adding filter aid, but it is the cost height not only, long-term use also may influence concentrating clarifying, purification and impurity removal, operations such as electrodeposition finished product.

The purpose of this utility model provides the magnetic force filter frame in a kind of Moor's filter, so that make the production order in order on original technological process basis and increase output not changing in the zinc hydrometallurgy factory.

The utility model is realized in the following manner, in the filter frame of existing Moor's filter, the sebific duct that keep support, polymerizer, clamping plate, links to each other with vacuum system, suspension ring, stopper, U-shaped pipe are constant, and remove low-quality easily the bamboo folding or the title bamboo strip mat of consumption, replace acidproof grid-shaped baffle plate grid, and adopt circle or square-section hollow tube to make the barrier bar, in the barrier bar, place magnetic thing such as bar magnet, electromagnetic core or neodymium iron boron magnetic body, form the magnetic force filter frame.

The utlity model has characteristics economic, durable, that be difficult for falling slag, the effect of its result of use and interpolation filter aid is suitable, and cost is much lower, and has no side effect.

Embodiment of the present utility model is provided by following accompanying drawing.

Accompanying drawing the 1, the 2nd, schematic appearance of the present utility model,

Below in conjunction with description of drawings concrete condition of the present utility model.

With reference to accompanying drawing, in the filter frame of Moor's filter, keep support, polymerizer, clamping plate, the sebific duct that links to each other with vacuum system, suspension ring, stopper, filter cloth (1), U pipe (2) is constant, after removing the bamboo folding, replace acidproof latticed barrier, and make barrier bar (3) with circle or square-section hollow tube, in barrier bar (3), place magnetic thing (4) as bar magnet, electromagnetic core or Nd-Fe-B permanent magnet, the placement of magnetic thing makes magnetic direction be parallel to the frame plane as shown in Figure 1, or make magnetic direction as shown in Figure 2 perpendicular to the frame plane, when adopting electromagnet, coiled electrical magnet is placed on the support, the magnetic line of force can make filter frame produce magnetic force by the iron core in the barrier bar, like this in Moor's filter hangs in pulp tank during operation, under negative pressure of vacuum and magneticaction, adhere on the filter cloth because of the filter residue in the ore pulp that wherein contains ferromagnetic is easier, its effect will with adopt the identical of filter aid.For making filter residue be easy to come off, can install a vibrator additional, the filter residue that shakes also can pour in down a chimney washing from the U-shaped pipe with the water of pulp slag.

Claims

1, the magnetic force filter frame of Moor's filter in a kind of zinc hydrometallurgy equipment, comprise support, polymerizer, clamping plate, the sebific duct that links to each other with vacuum system, suspension ring, stopper, U-shaped pipe, filter cloth, it is characterized in that in the described magnetic force filter frame, use a kind of acidproof latticed barrier, and get circle or the square-section hollow tube is made the barrier bar, in the barrier bar, place magnetic thing such as bar magnet, electromagnetic core or Nd-Fe-B permanent magnet.

2, magnetic force filter frame according to claim 1, the placement that it is characterized in that described magnetic thing are to make its magnetic direction parallel or perpendicular to the filter frame plane.
