Abstract
The utility model discloses a filtering device at the front of a pump and relates to an auxiliary device of a pump for conveying pulpified materials in the process of chemical metallurgy. The filtering device is characterized by comprising a sealed device cavity body and a filtering plate, wherein the side wall of the sealed device cavity body is provided with a discharging port and a feeding port, and the bottom of the sealed device cavity body is provided with a sewage draining port; and the filtering plate is obliquely arranged in the device cavity body. The filtering device disclosed by the utility model has the advantages that stainless steel plates and a stainless steel screen mesh are adopted for manufacture, the defects of blocking and locking of the pump are overcome, the requirements for conveying and filtering the pulpified materials in different fields can be met, large particles in the pulpified materials are prevented from blocking the pump and damaging an impeller and a shell of the pump, a certain protective action on the pump is achieved, and the filtered large particles are cleaned periodically; and the filtering device disclosed by the utility model has the obvious advantages of convenience for operation, simple manufacture process, good use effect and safety and the like and is simple to operate and maintain.
Description
Technical field
A kind of filtration device before pump relates to a kind of for the servicing unit of metallurgy chemical process conveying pulp material with pump.
Background technology
In metallurgy chemical process, usually to adopt pump to carry out the conveying transhipment of pulp material.For example in copper anode mud pressurization leaching process, must adopt pump to carry turnover to the pulp material, the pulp material is slurry, and wherein be mingled with a certain amount of large granular materials, cause the impeller of pump to stop up and damage, need the frequent impeller of changing, can't satisfy the quantity-produced needs, increased the repair and maintenance cost simultaneously.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provide a kind of can effectively solve exist in the slurry material be mingled with large granular materials to the obstruction of pump and impeller damage, have simple operation, make simple, result of use is good, effectively reduces the filtration device before pump of repair and maintenance cost.
For realizing the purpose of this utility model by the following technical solutions.
A kind of filtration device before pump is characterized in that its structure comprises:
Device cavity-this cavity is that a side wall upper part has discharging opening, relative opposite side bottom and has the airtight cylindrical shell that charging aperture, bottom have sewage draining exit;
Filter-this filter is the swash plate that has filter opening, and oblique being installed in the device cavity will be installed cavity and be divided into admission chamber and go out sap cavity; And device cavity discharging opening is located at out on the sap cavity sidewall, device cavity charging aperture is located on the admission chamber sidewall, sewage draining exit is located at bottom under the admission chamber.
A kind of filtration device before pump of the present utility model is characterized in that described device cavity top is that straight cylindrical cavity, bottom combine as a whole, are the contracting taper, and straight cylindrical cavity upper end is sealed by blind flange.
A kind of filtration device before pump of the present utility model is characterized in that discharging opening, the charging aperture on the described device cavity is provided with connecting flange, is provided with valve at sewage draining exit.
A kind of filtration device before pump of the present utility model, simple and reliable for structure, practical, with low cost; Can realize separating of foreign material and ore pulp effectively, protect follow-up delivery pump equipment, prolong follow-up equipment service life, guarantee the production continuity, improve production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of filtration device before pump, its structure comprises:
Device cavity 1-this cavity is that a side wall upper part has discharging opening 2, relative opposite side bottom and has the airtight cylindrical shell that charging aperture 3, bottom have sewage draining exit 4;
Filter 5-this filter is the swash plate that has filter opening, and oblique being installed in the device cavity will be installed cavity and be divided into admission chamber and go out sap cavity; And device cavity discharging opening is located at out on the sap cavity sidewall, device cavity charging aperture is located on the admission chamber sidewall, sewage draining exit is located at bottom under the admission chamber.
A kind of filtration device before pump of the present utility model, described device cavity top are that straight cylindrical cavity, bottom combine as a whole, are the contracting taper, and straight cylindrical cavity upper end is sealed by blind flange; Discharging opening, charging aperture on the described device cavity are provided with connecting flange, are provided with valve blind plate 6 at sewage draining exit.
A kind of filtration device before pump of the present utility model, filter divides the filter cavity admission chamber and goes out sap cavity, admission chamber side inlet links to each other by the outlet of flange with pulp material storage tank, and valve control is arranged, and the liquid outlet that goes out the sap cavity end side surface links to each other with the import of pump.
During operation, pulp material storage tank outlet valve is opened, start pump, the pulp material at first enters admission chamber, because the filtration of screen pack or plate, the foreign material bigger than the aperture are blocked in the admission chamber, owing to the gravity effect is deposited on the admission chamber bottom, and the pulp material enters out sap cavity, and enters in the pump with the liquid outlet pipeline.Along with the increase of material conveying amount, the foreign material of accumulation also can increase, and at this moment, lay down the valve blind plate of sewage draining exit, and foreign material are just discharged internally.
The utility model device has been realized separating of foreign material and pulp material effectively, has reduced the post employee and dismantles the number of times of pump and slotting, reduces labour intensity with dangerous, the service life of having improved production efficiency and pump apparatus.
On certain factory's silver production line, adopt this filtration device before pump that the pulp material is filtered.Used since 1 year, delivery pump does not have and stop up and the generation of impeller damage on-site, and periodic cleaning goes out a small amount of bulky grain except normal wear, and cleaning operation is succinct, greatly reduces the overhaul of the equipments frequency, has excellent application value.
