Abstract
The invention belongs to the technical field of filters of slurry pumps and particularly relates to a water-seal water-vortex discharge type filter of a slurry pump. The filter comprises a filter barrel body, a filter assembly, a water outlet pipe, an upper flange end cover and a lower flange end cover, wherein a central through hole is formed in the lower flange end cover; a water inlet is arranged on the barrel wall of the filter barrel body; the circumferential end of an external aperture of the water inlet is fixedly connected with the end of a water inlet pipe; the half circumferential end of an inner aperture of the water inlet is fixedly connected with an arc-shaped baffle; the lower flange end cover is connected with a set of sewage discharge devices; the central through hole in the lower flange end cover is a sewage outlet; and the arc-shaped baffle is an arc-shaped semi-circular pipe with a semi-circular cross section. According to the filter, water flow entering into the filter barrel body rotationally enters into the a barrel after the direction of the water flow is changed through the arc-shaped baffle, and a filter net in the filter assembly is not directly scoured, so that the service life of the filter net is prolonged; and impurities in water forming a rotary vortex can quickly sink down, so that the filter net is not easily blocked.
Description
Technical field
The invention belongs to the technical field of slag stock pump filter, but especially relate to a kind of slag stock pump water seal water eddy current pollution discharge type filter.
Background technology
Mill magnetic operation area is the synthetic job district that integrates ore grinding, sorting operation, and the water consumption of ore dressing is large especially, and is particularly outstanding after the enlarging.Because water consumption is large and water quality is bad, makes the used water seal water of slag stock pump contain a large amount of bits, foreign matter, often cause the water seal water pipeline to stop up, cause termination of pumping, fall pump, grinding machine and stop to faults such as ore deposits, seriously restrict the production direct motion.And the quality of slag stock pump running directly affects grading effect, when directly affecting concentrating table, grinding efficiency is descended.The while grinding machine stops the ore deposit and can the continuous and stable ore grinding of grinding machine be impacted, and the production run big rise and fall impacts for lower end production process.Original slag stock pump is because water seal water entrance caliber is thin and what adopt is the packing linear sealing, and water seal water pressure does not usually reach running requirements.Especially relatively poor in the water quality of water seal water, under bits, the more working environment of foreign matter, often cause the obstruction of packing water seal water inlet duct, packing linear sealing inefficacy, ore pulp ejection to enter axle box and make to revolve to the pump phenomenon that can not run well to occur.
The entrance and exit of original filter lays respectively on the upper and lower blind flange of filter cylinder, and its shortcoming is that current directly wash away filter screen, and filter screen is fragile, easily stops up, and it is little to use the saliva rheology, does not satisfy instructions for use; Bits pollution remaining after filtering can not in time be discharged, and blowdown must be carried out under stopped status, untimely equipment fault, the use inconvenience of easily causing of blowdown.
Summary of the invention
But the object of the present invention is to provide a kind of slag stock pump water seal water eddy current pollution discharge type filter, in the situation of not stopping equipment, can carry out blowdown by blowoff valve, and filter exempts to clean, saved the repair time, greatly improved grinding efficiency.
The objective of the invention is to realize by following technical proposals:
But slag stock pump water seal water eddy current pollution discharge type filter of the present invention, comprise filter cylinder and the filter assemblies that is located at this filter cylinder internal upper part, this filter assemblies is connected with outlet pipe, the upper end of described filter cylinder is provided with the upper flange end cap, this upper flange end cap is provided with the installing hole that is connected with described screen modules, the lower end of described filter cylinder is provided with the lower flange end cap, this lower flange end cap is provided with central through hole, it is characterized in that being provided with a water inlet at the barrel of described filter cylinder, the outer bore circumferential end of this water inlet is fixedly connected with a water inlet pipe termination, the interior bore semi-circumference end of this water inlet is fixedly connected with a curved baffle, described lower flange end cap is connected with a cover sewage discharging device, and the central through hole on the described lower flange end cap is outlet of sewer.
Described curved baffle is the semicircular arc semi-circular tube in cross section, an end of this arc semi-circular tube with are fixedly connected with in interior bore left semicircle week or the right semi-circle week of described water inlet, the other end of this arc semi-circular tube and inner arc surface are located at the place ahead of described water inlet.
Described sewage discharging device is by sewer pipe drain, the sewage discharging valve that is connected with sewer pipe drain lower end therewith of the adpting flange that is connected of sewer pipe drain upper end forms therewith, described adpting flange is fixedly connected with described lower flange end cap by one group of bolt assembly, and described sewer pipe drain is connected with described outlet of sewer.
Advantage of the present invention:
1) the present invention's characteristics of being provided with curved baffle are that the current that enter in the filter cylinder rotate in the cylinder after the curved baffle break-in, directly do not wash away the filter screen in the filter assemblies, prolong filter screen service life, form that impurity can sink fast in the water of rotating vortex, be difficult for stopping up filter screen;
2) the present invention can discharge the bits foreign matter that remains in the filter in the situation of not stopping equipment at any time.Effectively prevent from ensureing carrying out smoothly of producing because seal water pipe stops up termination of pumping, the phenomenon of falling the pump that causes, greatly improve grinding efficiency.
