Technical Field

[0001] The utility model relates to the technical field of sludge treatment dosing systems, in particular to an intelligent and precise dosing system suitable for sludge treatment. Background Art

[0002] After the centralized disposal and recycling of domestic sewage, a large amount of sludge is produced at the same time. Compared with domestic sewage, this sludge is more harmful and more difficult to treat. When treating the sludge, it is necessary to stabilize the sludge, that is, to use biological or chemical methods to treat the sludge to further reduce harmful substances and improve its properties, thereby preparing for the subsequent dehydration of the sludge and ensuring that the final product of the sludge treatment is pollution-free. During sludge treatment, a certain amount of chemical agents need to be regularly added to the sludge. In order to ensure uniform spraying of the agents, the staff need to mix the chemicals with water in advance and then add them to the sludge pool;

[0003] However, existing chemicals are usually mixed with water and then sprayed directly onto the sludge surface through a spray pump. Since the sludge contains a large amount of impurities and the water in the sludge has low fluidity, the chemical solution cannot quickly reach the bottom of the sludge, affecting the rapid reaction between the harmful components at the bottom of the sludge and the chemical solution. Therefore, it does not meet existing needs. In this regard, we propose an intelligent and precise dosing system suitable for sludge treatment. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-6 The present invention provides an embodiment of an intelligent precise dosing system suitable for sludge treatment, comprising a dosing bracket 1:

[0027] The rotating shaft 6 is fixedly mounted on the lower end of the dosing bracket 1, and a driving platform 7 is fixedly mounted on the upper end of the outer portion of the rotating shaft 6. The outer portion of the driving platform 7 is connected to a water pressure grid 8 by sliding up and down through a slot. The water pressure grid 8 is installed to cooperate with the driving platform 7 so that when the rotating shaft 6 rotates, the water pressure grid 8 can rotate with the rotating shaft 6, and the outer portion of the water pressure grid 8 is connected to the limiting corrugated bracket 19 by sliding through a slot, and the inner groove of the limiting corrugated bracket 19 is set to an arc-shaped wave shape, so that the water pressure grid 8 can reciprocate up and down when rotating, so that the water pressure grid 8 can squeeze the sludge up and down continuously, so that the sludge can be squeezed up and down. The water in the mud is disturbed longitudinally, and the auxiliary medicine can quickly enter the sludge and contact with the harmful components in the sludge, thereby enhancing the use effect of the device and improving the reaction efficiency of the medicine with the harmful components in the sludge. The outside of the water pressure grid 8 is slidably connected to the limited corrugated bracket 19 through a card slot. The outside of the limited corrugated bracket 19 is fixedly installed with a water filter basket 3. The installation of the water filter basket 3 allows the water in the sludge to pass freely, so that the water is mixed with the chemical agent in the water filter basket 3 to form a medicine. The medicine can flow back into the sludge through the water filter basket 3, so that the sludge is quickly mixed with the medicine, thereby enhancing the use effect of the device.

[0028] A mixing rod 16 is provided above the water pressure grid 8. Mixing brackets 17 are fixedly mounted on both ends of the mixing rod 16. A stirring rod 18 is fixedly mounted on the lower end of the outer portion of the rotating shaft 6. The installation of the mixing rod 16 enables the rotating shaft 6 to quickly mix the chemical agents during rotation, thereby enhancing the practicality of the device. The installation of the stirring rod 18 can mix the sludge and the chemical solution, thereby ensuring that the chemical agents react quickly with the harmful components in the sludge.

[0029] A spray water pump 9 is arranged at the front end of the upper end surface of the dosing bracket 1. A water suction pipe 11 is fixedly installed at the output end of the spray water pump 9. The water suction pipe 11 is fixedly connected to the dosing bracket 1. A spray pipe 10 is fixedly installed at the input end of the spray water pump 9. The installation of the spray water pump 9 can facilitate the rapid spraying of the medicine onto the upper end of the sludge, ensuring that the medicine and the sludge are quickly and evenly mixed. A dosing pump 13 is fixedly installed at the rear end of the upper end surface of the dosing bracket 1, and a dosing pipe 14 is fixedly installed at the output end of the dosing pump 13. A suction pipe 15 is fixedly installed at the input end of the dosing pump 13.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6A driving motor 4 is fixedly installed on the upper end of the dosing bracket 1, and the driving motor 4 is connected to the rotating shaft 6 through a coupling. A control box 5 is fixedly installed on one side of the upper end surface of the dosing bracket 1, and the control box 5 is fixedly connected to the dosing bracket 1. A liquid level sensor 20 is installed on the inner side of the water filter basket 3. The installation of the liquid level sensor 20 can detect the water level in the water filter basket 3 to prevent the spray water pump 9 from idling and avoid dry burning of the spray water pump 9. The liquid level sensor 20 is fixedly connected to the water filter basket 3. A medicine storage box 12 is installed at one end of the medicine suction pipe 15, and the medicine storage box 12 is fixedly connected to the medicine suction pipe 15. A sludge tank 2 is fixedly installed on the outside of the water filter basket 3, the dosing bracket 1 is fixedly connected to the sludge tank 2, and the mixing rod 16 is welded to the rotating shaft 6.

[0031] Working principle: When in use, the water in the sludge inside the sludge pool 2 passes through the water filter basket 3 and enters the water filter basket 3. The liquid level sensor 20 detects that the water level inside the water filter basket 3 reaches the safety threshold, and then the dosing pump 13 adds the chemical agent inside the medicine storage box 12 to the water filter basket 3 through the drug suction pipe 15 and the dosing pipe 14. At this time, the driving motor 4 drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it will drive the mixing rod 16 to rotate, and then drive the mixing bracket 17 to rotate, so that the water and chemical agents inside the water filter basket 3 are quickly mixed. Then the spray water pump 9 sprays the medicine evenly to the upper end of the sludge through the spray pipe 10 and the water suction pipe 11. At this time, the medicine inside the water filter basket 3 will pass through the water filter basket 3 directly into the sludge. When the rotating shaft 6 rotates, it will drive the driving platform 7 to rotate, and then the water pressure grid 8 rotates. Since the outside of the water pressure grid 8 is slidably connected to the limiting corrugated bracket 19 through a slot, and the inner groove of the limiting corrugated bracket 19 is set to an arc-shaped wave, the water pressure grid 8 can perform up and down reciprocating motion when rotating, so that the water pressure grid 8 can continuously squeeze the sludge up and down, causing the water in the sludge to be longitudinally disturbed, and the auxiliary liquid medicine can quickly enter the sludge and contact with the harmful components in the sludge, thereby enhancing the use effect of the device and improving the reaction efficiency of the liquid medicine with the harmful components in the sludge. When the rotating shaft 6 rotates, it will drive the stirring rod 18 to rotate, so that the stirring rod 18 mixes the sludge and the liquid medicine, ensuring that the chemical reagent reacts quickly with the harmful components in the sludge. This system uses the water in the sludge to mix with the chemical reagent, and does not require staff to inject new water into the sludge, ensuring that the total amount of sludge will not change too much, avoiding the generation of sewage, and making this system more green and environmentally friendly.
