The utility model content
Goal of the invention of the present utility model is that working as the pool bottom sludge amount at prior art reaches certain thickness, the main-shaft torque overload, fragile main shaft and motor, the labour intensity of manually removing contamination is big, the deficiency that implementation cost is high, provide a kind of, can stop to scrape mud automatically during the main-shaft torque overload and the scraper plate of will removing contamination promotes automatically and scrapes mud, the clarifier that labour intensity is low, running cost the is low scraper plate automatic lifting device of removing contamination with electric cabinet control.
Realize the foregoing invention purpose by the following technical solutions: a kind of clarifier scraper plate automatic lifting device of removing contamination, comprise electric cabinet, on, the lower case support, be installed in the remove contamination motor and the decelerator of removing contamination on the cabinet support, and scraper plate promotes motor and promotes decelerator, the described motor of removing contamination is connected with the decelerator of removing contamination, scraper plate promotes motor and is connected with the lifting decelerator, the motor of removing contamination, scraper plate promotes motor and is connected with control circuit in the electric cabinet respectively, described sliding key shaft is positioned at the lower case support, gear wheel is installed on it, this gear wheel is connected with pinion on being installed in the reducer output shaft of removing contamination, the upper end of sliding key shaft is connected with leading screw by Connection Block, described leading screw is positioned on the upper case support, big straight bevel gear is installed, described big straight bevel gear and the little straight bevel gear engagement that is installed on the lifting reducer output shaft on this leading screw.
Adopt technique scheme, compared with prior art, the clarifier of the present utility model scraper plate of removing contamination can promote automatically.(1) lifting of scraper plate by this device of removing contamination can stop to scrape mud automatically when scraping the mud overload, and the scraper plate of will removing contamination promotes certain altitude, with the scraper plate that guarantees to remove contamination scrape mud load non-overloading, make clarifier trash operate as normal, prolong its service life.
(2) automation control is the prerequisite that guarantees that the scraper plate main shaft can not overload, PLC control does not exist that electrical control noise such as relay is big, floor space is big, simultaneously because environment for use is relatively moister, make the degree of accuracy of control system control and the drawback that all is subjected to very big influence service life of parts, make entire equipment more small and exquisite, better effects if has improved the automaticity of clarifying operation.
(3) the utility model is rational in infrastructure simple, manufactures easily low, the good operating stability of cost.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is that circuit of the present utility model connects block diagram.
Among Fig. 1, Connection Block 1, the scraper plate sliding key shaft 2 of removing contamination, gear wheel 3, pinion 4, the motor 5 of removing contamination; big straight bevel gear 6, leading screw 7, leading screw protective cover 8, scraper plate promotes motor 9, little straight bevel gear 10; upper case support 11, Connection Block 12, bearing 13, lower case support 14, the scraper plate main shaft 15 of removing contamination.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to accompanying drawing 1, the motor 5 of removing contamination is connected with the decelerator of removing contamination, and is installed in lower case support 14 upper right side, and pinion 4 is installed on the output shaft that the decelerator of removing contamination stretches into lower case support 14 inside.The scraper plate sliding key shaft 2 of removing contamination is installed in the lower case support 14, and gear wheel 3 is installed on it, and its lower end links to each other with Connection Block 1, gear wheel 3 and pinion 4 engagements.Remove contamination scraper plate sliding key shaft 2 tops by Connection Block 12 and 7 coaxial connections of leading screw, in the Connection Block 12 between scraper plate sliding key shaft 2 and the leading screw 7 of removing contamination bearing 13 is housed.The top of leading screw 7 is installed with big straight bevel gear 6, and upper case support 11 is passed in the top of leading screw 7, is positioned at outside the upper case support 11, is covering protective cover 8 on it.The remove contamination lower end of scraper plate sliding key shaft 2 is equipped with Connection Block 1, and the lower end of the scraper plate sliding key shaft 2 of removing contamination is connected with the scraper plate main shaft 15 of removing contamination that is positioned at its below.Scraper plate promotes motor 9 and is connected with the scraper plate decelerator, is installed in upper case support 11 upper left sides, and little straight bevel gear 10 is installed in scraper plate lifting decelerator and stretches on the output shaft of upper case support 11 inside, little straight bevel gear 10 and big straight bevel gear 6 engagements.Pinion 4, gear wheel 3 and the scraper plate sliding key shaft 2 of removing contamination are installed in the lower case support, and little straight bevel gear 10, big straight bevel gear 6 and leading screw 7 are installed in the upper case support.
Referring to accompanying drawing 2, scraper plate promotes motor 9 and is connected with electric cabinet, and the motor of removing contamination is connected with electric cabinet.Programmable Logic Controller PLC is contained in the electric cabinet, is used to control remove contamination connect overload detector on the circuit of motor 5, and the output line of this overload detector is connected with the control circuit that scraper plate promotes motor 9.
