Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-4, the present embodiment provides a blockage preventing device for a mud lifting valve of a secondary sedimentation tank, which comprises a mud suction scraper 8 driven by a power mechanism 1 to rotate, a plurality of mud suction pipes 2 are arranged on the mud suction scraper 8, the lower ends of the mud suction pipes 2 are connected with a mud scraper 4 together, a mud discharge pipe 1 is arranged on the power mechanism, a mud collection groove 6 is arranged at the upper end of the mud suction pipe, the mud suction scraper performs circular motion along the top of the tank, because the liquid level in the mud collection groove is lower than the liquid level in the tank, under the action of the liquid level difference, the mud in front of the mud scraper is sucked into the mud collection groove through a horn mouth by the mud suction pipe, the mud lifting valve at the top of the mud suction pipe controls the size of the mud, the mud lifting valve 7 is communicated with the mud suction pipe 2, the lower end of the mud suction pipe 2 is provided with a horn mouth 9, a dredging rod 15 horizontally penetrates through the end of the mud suction pipe 2 adjacent to the horn mouth 9, the dredging rod 15 can slide freely on the mud suction pipe 2, a telescopic cylinder 5 is installed with a telescopic support plate, the telescopic cylinder 5, and the cylinder is driven by the cylinder, the telescopic rod, the cylinder can be driven by the cylinder to move horizontally, and the cylinder to drive the dredge rod, thereby the cylinder to generate a blockage preventing device.

The connecting unit includes the connecting rod 14 of being connected (can set for the welding here) with the cylinder pole drive of telescopic cylinder 5, the one end that dredging rod 15 wore out mud suction pipe 2 is equipped with U-shaped frame 13, connecting rod 14 lower extreme is equipped with loose ring 11, wear to be equipped with short pin 10 on the loose ring 11, connecting rod 14 lower extreme is free activity in the defect position 17 of U-shaped frame 13, and be equipped with the waist shape hole 12 that supplies short pin 10 to insert on the outer wall of U-shaped frame 13, waist shape hole 12 length direction becomes contained angle and non-perpendicular with dredging rod 15 axial, when telescopic cylinder's cylinder pole shortens, drive short pin upwards slides, and the short pin slides in the waist shape hole, can know through figure 3, when the short pin slides up, will drive U-shaped frame and remove towards the inboard direction of mud suction pipe, and make the dredging rod penetrate in the mud suction pipe, so as to dredge the silt in the mud suction pipe, avoid silt to block up the mud suction pipe.

The minimum value of the included angle between the length direction of the waist-shaped hole 12 and the axial direction of the dredging rod 15 is set to be not more than 45 degrees, so that the resistance of the short pin 10 in the sliding process in the waist-shaped hole is small, and the over-tolerance of the abrasion loss of the short pin is avoided.

Be equipped with registration arm 16 on the 2 outer walls of suction pipe, dredge on the coaxial slip of pole 15 wears to locate registration arm 16, through setting up the registration arm, has the guide effect when making the dredging pole slide like this, avoids dredging pole to produce bending deformation.

In this embodiment, the power circuit breaker 20 of the mud suction and scraping machine 8 and the electromagnetic valve 21 connected with the telescopic cylinder 5 are electrically connected with a controller 19, the controller 19 is electrically connected with a time relay 18, the time relay sets the timing duration according to limited experiments by technicians in the field, and then the power supply of the power circuit breaker 20 and the electromagnetic valve 21 can be controlled to be on or off, so that the mud suction and scraping machine 8 can be started intermittently, the phenomenon that the mud in the mud suction pipe is blocked is avoided, through the setting of the electromagnetic valve, when the electromagnetic valve is powered on, the compressed air generated by external compressed air equipment is controlled to be conveyed into the telescopic cylinder through the valve body of the electromagnetic valve, and then the telescopic cylinder generates actions, namely, the cylinder rod of the telescopic cylinder is extended or shortened, so as to drive the action of the dredging rod and the action of the mud suction and scraping machine, so that the person is not needed to control the intermittent action (starting and stopping) of the mud suction pipe, and further avoid the blocking of the mud suction pipe, and the labor intensity is reduced. For example, when the sludge clogs, it stops for 60 seconds and then starts for 5 seconds. After a period of time, the state is changed into stopping for 30 seconds, starting for 10 seconds, then stopping for 10 seconds, starting for 10 seconds, and finally, the normal continuous work is realized.

The advantages are that: the work that would have been completed in 72 hours and required at least two people to look at it can now be completed in 24 hours without the need for a worker to watch it.
