Abstract
The utility model relates to a scrapper type filter, which is used for filtering mud on a spiral spraying pump in the spiral spraying construction technology. A filter screen is uneasy to block; the scrapper type filter has good filtration effect and ensures the continuous work of the spiral spraying pump. The shell body of the scrapper type filter is connected into one body with a multi-spiral mud feeding pipe (9); a spiral rotor (1) whose front end is connected with a scrapper (3) is supported by a bearing (10) in the pipe. The mud is rotated to drive the rotor, the scrapper and the hair brush (7) on the scrapper to rotate; impurities on the filter screen can be effectively removed. The utility model has the advantages of good filtration effect, strong self-cleaning capacity, difficult jam of the filter screen, large mud throughput, simple result, convenient maintenance, stable performance, and long continuous operation time, etc.
Description
The utility model relates to a kind of filter, particularly a kind of Wiper blade type filter that is used for filtering on the rotary-jet pump mud.
Rotary-spraying construction technology be development in recent years get up newly advance construction method.Be mainly used in the construction of water conservancy and hydropower cut-pff wall, grout curtain; Skyscraper wall construction, Metro Tunnel construction and the similar construction occasion of other industry.The high-pressure rotary-spray pump is one of key equipment of implementing this technology.The high-pressure rotary-spray pump of some introductions is not with filtration system, and the stock inlet of pump only adopts silk screen filter.Network is thick excessively, and the grains of sand in the stone grain cement mortar easily enter rotary-jet pump, and fluid end is not closed completely into and out of slurry valve, movement parts serious wear such as valve, valve seat, plunger, lining.If filter grid is thinner, then advancing to starch resistance increases, and filter screen is torn, and causes the rotary-jet pump operating pressure to reduce suddenly, and equipment is forced to shut down.The major accident that also can cause rotary-jet pump to stop up when serious in case plugged filter is condensed in the bar in pump for preventing cement slurrypump, often will be pulled down pulp-inlet pipe, peace and quiet filter, and the mud of wasting water is incured loss through delay construction.
The purpose of this utility model provides a kind of being used for and filters mud on the rotary-jet pump, makes screen pack be difficult for stopping up and good filter effect is arranged to keep the Wiper blade type filter of rotary-jet pump continuous operation.
Described Wiper blade type filter comprises parts such as filter housings, feed pipe for mortar, screen pack, ring flange, housing and feed pipe for mortar are connected as a single entity, another termination slurry supply pump of feed pipe for mortar, housing links to each other with rotary-jet pump by pipeline through ring flange, feature of the present utility model is: feed pipe for mortar is a kind of multi-start helical tubes (9), supporting the helical rotor (1) of front end band one scraping blade (3) by two bearings (10) in the helix tube; Scraping blade, filter screen are in filter housings (2) cavity, and hairbrush (7) is housed on the scraping blade, and scraping blade contacts with filter screen (4) through hairbrush.A sediment bowl (6) is equipped with in filter housings (2) lower end, and the upper end is furnished with the Pressure gauge (5) of an indication cavity pressure.
When cement mortar when slurry supply pump enters filter, swiftly flowing mud impacts helical rotor, makes it to rotate and drive scraping blade and hairbrush rotation, and constantly the contaminant removal that will stick on the filter screen falls, under the gravity effect, coarse granule impurity is collected in the sediment bowl of filter screen lower end.The continuous rotation that hairbrush on the scraping blade goes round and begins again can make filter screen keep clear, and only impurity can guarantee that long time continuous working does not have obstruction in the regular scavenger precipitation cup of need.Conclusion is got up, and the utility model has the advantages that: (1) good filtration effect, self-cleaning ability is strong.(2) screen pack does not stop up, and the liquid handling capacity is big.(3) simple in structure, easy to maintenance.(4) stable performance, stream time is long.
Description of drawings.Fig. 1 is the utility model structural principle schematic diagram.Among the figure: (1) is helical rotor, and (2) are filter housings, and (3) are scraping blades, and (4) are filter screens, and (5) are Pressure gauges, and (6) are sediment bowls, and (7) are hairbrush, and (8) are pipelines, and (9) are helix tubes, and (10) are bearings, and (11) are ring flanges.
The helical rotor of described filter needs bearing supporting, and bearing needs to seal well in cement mortar, otherwise the rotor motion resistance will increase, and this is the problem that should be noted that.The gap will be adjusted between scraping blade and the filter screen, cleans effect with water to guarantee the best.Because wearing and tearing, hairbrush need regularly replace.Helix tube is good with three spirals.
Claims (2)
1. Wiper blade type filter, comprise parts such as filter housings, feed pipe for mortar, screen pack, ring flange, housing and feed pipe for mortar are connected as a single entity, another termination slurry supply pump of feed pipe for mortar, housing links to each other with rotary-jet pump by pipeline through ring flange, it is characterized in that: described feed pipe for mortar is a kind of multi-start helical tubes (9), is being supported the helical rotor (1) of front end band one scraping blade (3) in the helix tube by two bearings (10); Scraping blade, filter screen are in filter housings (2) cavity, and hairbrush (7) is housed on the scraping blade, and scraping blade contacts with filter screen (4) through hairbrush.
2. Wiper blade type filter according to claim 1, it is characterized in that: a sediment bowl (6) is equipped with in described filter housings (2) lower end, and the upper end is furnished with the Pressure gauge (5) of an indication cavity pressure.
