Abstract

The utility model discloses a dirt removing machine, which can continuously realize dirt blockage of an entire section and mechanized dirt removal to the water inlet of a pump station. The utility model is composed of rake teeth, a machine frame, a transmission system, a dirt blocking grate, a power system, dirt accepting device, etc. The dirt blocking grate fully fills the entire water inlet section with complete dirt blockage. The rate teeth conduct directional backward rotation on the front edge of the dirt blocking grate. When the rake teeth are in operation, a dirt scraping claw is inlaid into grilles of the dirt blocking grate to form the dirt scrape of left, right and upper sides with a dirt scraping plate which is transversely arranged. The dirt scraping ability is increased. The rake teeth can rotate by winding a fulcrum and automatic avoidance can be provided when the dirt is clamped. The rake teeth can rotate out from a water surface. The service life is increased.

Description

Preceding rotary type trash cleaning device

The utility model relates to the dirt-blocking dirt-cleaning device of intakes of pumping station, can realize filtering and removing dirt for the pumping plant water inlet.It is the dirt-blocking dirt-cleaning device of middle-size and small-size intakes of pumping station.

Existing rotary type trash cleaning device mainly contains compositions such as trashrack, rake teeth, transmission system, frame.The rake teeth of trash rake is done directed revolution continuously around trashrack under the driving of transmission system, rake teeth move to blocking of trashrack dirty in face of the time, rake teeth scrapes on the dirty face of blocking of trashrack from bottom to top, rake teeth will be adsorbed onto dried up of the dirt band in trashrack forward position, by scraping dirty dolly (or freely falling) dirt is delivered to the device of getting dirty when rake teeth arrival movement locus upper end turns to, rake teeth returns to circle finishes the process of once removing contamination.This mechanism is because rake teeth turns round around trashrack, and trashrack must leave the gap with the water inlet bottom to be passed through for rake teeth, and dirt tends to enter the pump chamber influence and blocks dirty effect in this gap, be referred to as to block dirty dead angle sometimes.And when dirt is hampered by in this gap, can influence rake teeth pass through cause that facility damage.

The utility model can not only keep simple in structure, the advantages such as the production use cost is low, the maintenance is convenient, simple to operate, mechanized of rotary type trash cleaning device, rake teeth revolution in face of trashrack blocks dirt does not simultaneously exist blocks dirty dead angle, can realize that total cross-section blocks dirt, rake teeth and transmission system can be rotated on driving axial together, also can dodge automatically when running into the dirt blocked portion.Adopt left side, right side and block the structure that dirty face (top) three sides are scraped dirt simultaneously, improved the dirty ability of scraping of rake teeth greatly.Rake teeth and transmission system can produce the water surface during non-operation, improve aseptic condition.

The purpose of this utility model: thoroughly solve the dirty dead angle problem of blocking of existing rotary type trash cleaning device, realize the total cross-section dirt-blocking dirt-cleaning.Adopt three sides to scrape dirty scheme and improve and improved machinery and scrape dirty ability, rake teeth and transmission system can be around drive shaft turns, and the movement parts that has solved existing rotary type trash cleaning device can only the problem of long period of soaking in water.

The purpose of this utility model is achieved in that trashrack is arranged in whole water inlet cross section, and the dirt that moves with water inlet is filtered by trashrack all, does not have the dirty dead angle problem of blocking.Rake teeth is done the continuously-directional gyration in the trashrack forward position, when rake teeth is turned back to lower dead center, the dirt-wipping claw of rake teeth embeds in the trashrack grid blade gap distance, and laterally dirt-scraping plate is pressed close to the dirty face of blocking of trashrack, rake teeth scrapes dirt from bottom to top, and dirt enters in the rake teeth bucket up and take the water surface out of with rake teeth.When rake teeth arrival top dead centre turned to, (or freely falling) dirt was fallen in the device of getting dirty under the help of apparatus for scratching dirt, and rake teeth continues to be turned back to lower dead center, enters next working cycles process.The dirt-wipping claw of the utility model rake teeth embeds in the trashrack grid blade gap distance, the dirt-wipping claw that embeds in the trashrack grid blade gap distance is scraped dirt with the leaf one-tenth and arranged on left and right sides of adjacent trashrack grid, and laterally dirt-scraping plate blocks dirty face with trashrack and forms upside and scrape dirt and promptly be referred to as " about last three sides scrape dirt ".Rake teeth and transmission system can be around drive shaft turns, and become to float with trashrack and contact, when by dirt blocked portion greatly, rake teeth can laterally rotate around driving shaft automatically, rake teeth is thrown off trashrack increases rake teeth with the spacing between the trashrack, can dodge dirt, resets under current and deadweight effect subsequently.During non-operation, rake teeth and transmission system can produce the water surface.

Owing to adopted such scheme, do not had the dirty dead angle of blocking of rotary type trash cleaning device problem.Left side, right side, upper side three sides are scraped dirt simultaneously, have improved the dirty ability of scraping.The split type motion and the contact design of floating can avoid rake teeth and transmission system long period of soaking in water, have improved aseptic condition.

In the accompanying drawing, trashrack (1) becomes 0～30 degree angle to arrange (seeing α angle in the accompanying drawing) with the water inlet vertical guide, is full of whole rectangle water inlet cross section.It is chain drive and chain case along the left and right sides that transmission system (2) is arranged in that trashrack blocks in face of dirty, and respectively having about the lower end one can only be around connecting the wheel that both sides chain guard columella rotates and forming chaindriven lower dead center.The upper end chain is driven by two drive sprockets on the driving shaft (8), and forms chaindriven top dead centre.The chain case connects with the driving shaft hinge pin.Rake teeth (3) two ends are fixedly mounted on the chain of transmission system (2) both sides, can move with chain movement, transmission system (2) and rake teeth (3) can be around drive shaft turns, rake teeth and transmission system under the effect of deadweight and water inlet can fall automatically to trashrack block dirty in face of the edge, spacing and forms to float and contact by the mechanism on the trashrack.Power set (6), driving shaft (8) are the mechanisms that carries the power of removing contamination.Frame (5) is each member of fixed installation.The device (4) of getting dirty is to contain the dirt that is eliminated.Apparatus for scratching dirt (7) is to assist to scrape dirty parts.Dirt-wipping claw on the rake teeth (3) puts in the interior left and right sides that forms of grid blade gap distance of trashrack and scrapes dirt, and the last dirt-scraping plate of rake teeth (3) is pressed close to the dirty face formation of blocking of trashrack (1) upside and scraped dirt.
