Description
Technical Field
The utility model relates to a two cold water back flush filter belt cleaning device of continuous casting belongs to metallurgical industry continuous casting equipment technical field.
Background
The back flushing filter for secondary cooling water in continuous casting is a common filter for secondary cooling water system in continuous casting, and mainly comprises: the suction nozzle is a core component on the back flush filter and is a key component for removing impurity particles on the inner wall of the filter element.
Sewage enters the filter through the water inlet pipe and then passes through the filter element from inside to outside, and when water flows out from inside to outside, impurities are accumulated on the inner surface of the filter element. When the difference between the water pressure in and out of the filter reaches a preset value or reaches a preset time interval, the filter starts to self-clean. When the filter is self-cleaned, the positive and negative rotation bidirectional motor drives the suction scanner to rotate and move linearly along the axial direction through the lead screw to form spiral motion, and simultaneously, the drain valve is opened, and impurities on the filter element are sucked away by the suction nozzle by utilizing the pressure difference between the water pressure in the filter and the atmospheric pressure outside the drain valve. But for the part of impurities with strong adhesive force, the impurities still adhere to the inner wall of the filter element, and the filtering effect is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a two cold water back flush filter belt cleaning device of continuous casting can clear away the impurity that the adhesive force is strong on the filter core inner wall, improves the filter effect of filter, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides a two cold water back flush filter belt cleaning device of continuous casting, contain the filter core, the suction nozzle, suck the scanner, lead screw and two-way motor of just reversing, the filter core is the cylinder, the lead screw is located the central axis of filter core, two-way motor of just reversing is connected with the lead screw drive, suck scanner threaded connection on the lead screw, the suction nozzle is connected on sucking the scanner, the suction nozzle is close to the inner wall of filter core, be equipped with a steel brush that contacts with the filter core inner wall respectively in the both sides of suction nozzle, every steel brush passes through the steel brush seat and fixes on the suction nozzle.
The steel brush is of a long strip shape and is arranged in parallel with the central axis of the filter element.
The steel brush seat is rectangular and matched with the steel brush, the steel brush seat is fixed on the suction nozzle, the steel brush is fixed on the steel brush seat, and the steel brushes on two sides of the suction nozzle and the steel brush seat are symmetrically arranged.
Adopt the utility model discloses, during back flush filter self-cleaning, positive reverse rotation bidirectional motor sucks the scanner through lead screw drive and makes spiral reciprocating motion in the filter core, and partial impurity on the filter core inner wall is siphoned away through the suction nozzle, is then siphoned away by the suction nozzle after under the steel brush to the impurity that the adhesion is strong to reach the effect of rinse thoroughly filter screen.
The utility model has the advantages that: can clear away the impurity that the adhesion is strong on the filter core inner wall, improve the filter effect of filter, prolong the artifical cycle of wasing the filter screen greatly.

Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings 1-4, a continuous casting secondary cold water backwashing filter cleaning device comprises a filter element 1, a suction nozzle 4, a sucking scanner 5, a lead screw 6 and a forward and reverse rotation bidirectional motor, wherein the filter element 1 is a cylinder, the lead screw 6 is positioned on a central axis of the filter element 1, the forward and reverse rotation bidirectional motor is in driving connection with the lead screw 6, the sucking scanner 5 is in threaded connection with the lead screw 6, the suction nozzle 4 is connected to the sucking scanner 5, the suction nozzle 4 is close to the inner wall of the filter element 1, steel brushes 2 in contact with the inner wall of the filter element 1 are respectively arranged on two sides of the suction nozzle 4, and each steel brush 2 is fixed on the suction nozzle 4 through a steel brush seat 3.
In this embodiment, referring to fig. 1 to 4, the steel brush 2 is a strip and is arranged parallel to the central axis of the filter element 1, the steel brush holder 3 is a rectangle matched with the steel brush 2, the steel brush holder 3 is fixed on the suction nozzle 4, the steel brush 2 is fixed on the steel brush holder 3, and the steel brush 2 and the steel brush holder 3 on both sides of the suction nozzle are symmetrically arranged.
When the backwashing filter is self-cleaned, the forward and reverse rotation bidirectional motor drives the sucking scanner 5 to do spiral reciprocating motion in the filter element 1 through the screw rod 6, part of impurities on the inner wall of the filter element 1 are sucked away through the suction nozzle, and impurities with strong adhesive force are brushed down through the steel brush 2 and then are sucked away by the suction nozzle, so that the effect of thoroughly cleaning the filter screen is achieved.
