Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking of mud discharge channels in air flotation tanks, in particular to an anti-blocking mud discharge channel spraying device. Background Art

[0002] In the field of electroplating wastewater treatment, electroplating wastewater containing metal ions is treated by chemical methods such as acid-base neutralization, oxidation-reduction and iron-oxygen method to separate the metal ions and various highly toxic substances in the electroplating wastewater. Flocculants are also added to the electroplating wastewater to completely precipitate the heavy metal ions in the electroplating wastewater into sludge in the form of hydroxides. The current technology mainly uses flotation to separate sludge and electroplating wastewater. The existing treatment equipment includes a dissolved air water generator and a scraper. The connecting pipe of the water pipe of the dissolved air water generator extends into the flotation tank containing sludge, and the dissolved air water is discharged, thereby releasing a large number of tiny bubbles. The bubbles adsorb the sludge particles and make the sludge particles float to the surface of the sludge flotation tank, and then the sludge is discharged through the sludge discharge channel. Most of the existing sludge discharge channels are channels with an inclined bottom structure, and the inclination angle is not large. When discharging sludge, the sludge is easy to adhere to the bottom of the sludge discharge channel, causing the sludge discharge channel to be blocked, thereby affecting the sludge discharge.

[0003] To this end, the utility model provides a spray device for preventing mud drainage channels from being blocked. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: an anti-clogging mud drainage channel spraying device, including a mud drainage channel 1, on which two sliders 3 are slidably matched, a rotating shaft 5 is rotatably matched between the two sliders 3, a swivel 6 is rotatably matched on the rotating shaft 5, a mounting plate 9 is fixed on the swivel 6, a plurality of high-pressure nozzles 10 are installed on the mounting plate 9, connecting rods 12 are fixed at both ends of the rotating shaft 5, a push plate 13 is installed between the two connecting rods 12, and the push plate 13 is located in the mud drainage channel 1.

[0022] In this embodiment, rodless cylinders 2 are fixed on both sides of the mud discharge channel 1 , and the output ends of the rodless cylinders 2 are fixedly connected to the sliders 3 .

[0023] The rodless cylinder 2 can drive the slider 3 to slide on the mud discharge channel 1, so that the inside of the mud discharge channel 1 can be slid and flushed, thereby preventing the inside of the mud discharge channel 1 from being blocked.

[0024] A motor 4 is fixed to one side of the slider 3, and the output end of the motor 4 is fixedly connected to the rotating shaft 5. A through groove 15 is opened in the rotating ring 6, and the through groove 15 corresponds to the rotating shaft 5. A plurality of friction protrusions 16 are fixed in the through groove 15. Two limit rods 14 are fixed between the two sliders 3. The limit rods 14 are located on both sides of the mounting plate 9, and a gap is provided between the limit rods 14 and the mounting plate 9.

[0025] Specifically, when the spray angle needs to be changed, the motor 4 is started so that the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives the swivel 6 to rotate under the action of friction. The swivel 6 can drive the high-pressure nozzle 10 to rotate through the mounting plate 9, thereby changing the spray angle until the mounting plate 9 contacts the limit rod 14. At this time, the limit rod 14 limits the mounting plate 9, so the rotation of the rotating shaft 5 will not drive the swivel 6 to rotate. At this time, the rotating shaft 5 drives the push plate 13 to rotate at a larger angle.

[0026] A main water pipe 7 is fixed on the slider 3 , and a branch water pipe 8 is installed between the main water pipe 7 and the high-pressure nozzle 10 .

[0027] Water can be delivered to the high-pressure nozzle 10 through the main water pipe 7 and the branch water pipe 8, so as to spray the mud discharge channel 1.

[0028] Both ends of the rotating shaft 5 are fixed with a fixing ring 11, and the fixing ring 11 is fixedly connected to the connecting rod 12. The bottom of the push plate 13 is a comb-tooth structure, and the bottom of the push plate 13 contacts the bottom of the mud discharge channel 1, and the bottom of the mud discharge channel 1 is an inclined structure.

[0029] Specifically, when the mud discharge channel 1 is blocked, the motor 4 is started to drive the rotating shaft 5 to rotate, so that the bottom of the push plate 13 contacts the bottom of the mud discharge channel 1, and then the rodless cylinder 2 is started to drive the push plate 13 to slide, thereby clearing the blocked part.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
