Description
Technical Field
[0001] This utility model relates to the field of automation technology, and in particular to an automatic flushing module for an internal flow grille. Background Technology
[0002] The internal flow bar screen is equipped with a reliable screen washing system. The washing system starts and stops simultaneously with the internal flow bar screen. Fixed nozzles are installed at the top of the internal flow bar screen. By adjusting the spray direction of the nozzles, the bar screen is washed, effectively removing most of the dirt trapped by the screen.
[0003] Currently, traditional fixed flushing nozzles with internal flow bar screens cannot meet the requirements for high-efficiency removal of contaminants, so it is necessary to improve the fixed flushing nozzles. Utility Model Content
[0004] The purpose of this invention is to provide an automatic flushing module for an internal flow grille to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An automatic flushing module for an internal flow bar screen includes an internal flow bar screen machine and a high-pressure cleaning module disposed at the top of the internal flow bar screen machine. The high-pressure cleaning module is used to flush the bar screen of the internal flow bar screen machine. The high-pressure cleaning module includes a first fixed plate, a second fixed plate, a servo motor, a screw, a first slider, a second slider, a first limiting rod, and a second limiting rod. The first fixed plate and the second fixed plate are disposed opposite to each other at the left and right ends of the top inner part of the internal flow bar screen machine.
[0007] One end of the first limiting rod is fixedly connected to the top of the first fixed plate, and the other end of the first limiting rod is connected to the top of the second fixed plate. The axes of the screw and the second limiting rod are parallel to the axis of the first limiting rod. The screw is spaced apart at the bottom of the first limiting rod, and the second limiting rod is spaced apart at the bottom of the screw. The left ends of the screw and the second limiting rod are both connected to the first fixed plate, and the right ends of the screw and the second limiting rod are both connected to the second fixed plate.
[0008] Both ends of the screw are fitted with bearing seats, and both ends of the screw are connected to the first fixed plate / second fixed plate respectively through bearings. The servo motor is fixedly mounted on the second fixed plate. The output shaft of the servo motor is connected to the right end of the screw through a coupling. The right end of the coupling is rotatably connected to the output shaft of the servo motor, and the left end is rotatably connected to the right end of the screw. The coupling can ensure that the two shafts rotate synchronously.
[0009] The first slider and the second slider are both screwed onto the screw rod, and there is a gap between the first slider and the second slider. The top ends of the first slider and the second slider are slidably connected to the first limiting rod, and the bottom ends of the first slider and the second slider are slidably connected to the second limiting rod.
[0010] Both the first slider and the second slider are provided with nozzles, and the nozzles are fixedly installed on the first slider and the second slider.
[0011] By adopting the above technical solution, when the internal flow bar flushing module starts working, the output shaft of the servo motor fixedly installed on the second fixed plate drives the screw to rotate through the coupling. Because the screw is fitted with bearing seats at both ends, the screw will drive the first slider and the second slider to move. Under the limitation of the first limit rod and the second limit rod, the first slider and the second slider will start to make a reciprocating motion within a certain range. The nozzle will change position with the movement of the first slider and the second slider, so that the water flow sprayed from the nozzle can thoroughly and efficiently flush the internal flow bar machine.
[0012] In a further embodiment, a first collision switch is provided on the right side of the first fixing plate, a second collision switch is provided on the left side of the second fixing plate, the first slider is located to the left of the second slider, a first striking rod adapted to the first collision switch is provided at the left end of the first slider, and a second striking rod adapted to the second collision switch is provided on the right side of the second slider.
[0013] By adopting the above technical solution, when the screw starts to move under the drive of the servo motor, the first slider and the second slider also start to move to the left or right under the limitation of the first limit rod and the second limit rod. Thus, when the first strike rod at the left end of the first slider collides with the first collision switch located at the upper right end of the first fixed plate, or when the second strike rod at the right end of the second slider collides with the second collision switch located at the upper left end of the second fixed plate, the first collision switch and the second collision switch will immediately receive the collision information and then transmit the electrical signal to the servo motor, so that the servo motor changes the rotation direction, the screw also changes the rotation direction, and thus changes the movement direction of the first slider and the second slider.
[0014] In a further embodiment, the first fixing plate is fixedly connected to the inner wall of the inner flow bar screen machine via a first end face bearing, and the second fixing plate is fixedly connected to the inner wall of the inner flow bar screen machine via a second end face bearing. A variable frequency motor is fixedly installed on the inner wall of the inner flow bar screen machine, and a first gear is sleeved on the output shaft of the variable frequency motor, and a second gear is sleeved on the second end face bearing. The first gear and the second gear mesh.
[0015] In a further embodiment, the nozzle is connected to a high-pressure water tank via a high-pressure pipe, the high-pressure water tank being used to provide a high-pressure water flow to the nozzle.
[0016] In a further embodiment, brushes are provided at both the left and right ends of the first slider and the second slider.
[0017] In a further embodiment, both the first limiting rod and the second limiting rod are round rods.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. By setting a first collision switch and a second collision switch on the upper right side of the first fixed plate and the upper left side of the second fixed plate of the internal flow bar screen, and setting a first striking rod and a second striking rod adapted to the first collision switch and the second collision switch on the left side of the first slider and the right side of the second slider, the bar screen of the internal flow bar screen can be cleaned in an all-round way with high efficiency.
