Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment, and specifically relates to a flocculant dosing device. Background Art

[0002] The methods of water treatment include physical treatment and chemical treatment. Humans have had a history of water treatment for quite a long time. Physical methods include using various filter materials with different pore sizes to exclude impurities in water by adsorption or blocking. In the adsorption method, the more important one is adsorption with activated carbon. The blocking method is to pass water through the filter material so that larger impurities cannot pass through, thereby obtaining relatively clean water. At the same time, flocculants are also used to assist in water purification.

[0003] A Chinese patent with the publication number CN209155720U discloses a flocculant dosing device, which includes a stirring barrel, a water inlet pipe arranged above the stirring barrel, and a flocculant addition tank; a necking part is arranged at the lower end of the flocculant addition tank, and a regulating valve is arranged on the necking part; it also includes a heating and stirring device, which includes an air heater, a first gas booster pump, a second gas pipeline, and a first gas pipeline connecting the air heater and the first gas booster pump. The output end of the first gas booster pump is communicated with the air inlet of the second gas pipeline, and the air outlet of the second gas pipeline is arranged on the bottom wall of the stirring barrel, and a check valve is arranged on the second gas pipeline; a liquid delivery pipe is also communicated with the bottom of the stirring barrel, a flow valve is arranged on the liquid delivery pipe, and the liquid outlet end of the liquid delivery pipe is arranged above the sewage tank.

However, this dosing cannot ensure that the flocculant can be evenly sprinkled into the water, resulting in insufficient use of the flocculant. Moreover, the sizes and shapes of the flocculants used in this dosing are different, so the dissolution time in water is inconsistent, and the water purification time limit is difficult to guarantee.

[0005] Therefore, a flocculant dosing device is proposed to solve the above problems. Summary of the Utility Model

[0024] Specific embodiments are given below.

[0025] Please refer to Figure 1 - Figure 5 , the present utility model provides a flocculant dosing device, including a base 1 and a dosing tank 2; an elastic sieve plate 3 is fixedly connected to the inner wall of the dosing tank 2; a transmission shaft 4 is rotatably connected to the surface of the elastic sieve plate 3; a crushing blade 5 is fixedly connected to the surface of the transmission shaft 4; a rotating shaft 6 is rotatably connected to the bottom of the elastic sieve plate 3 and located inside the dosing tank 2; a vibration cam 7 is fixedly connected to the surface of the rotating shaft 6; a discharge hole is opened at the bottom of the inner wall of the dosing tank 2; a scraping plate 8 is slidably connected to the bottom of the inner wall of the dosing tank 2; both sides of the surface of the scraping plate 8 are slidably connected with a bidirectional reciprocating lead screw 9 and a limiting rod; during operation, the elastic sieve plate 3 is fixed inside the dosing tank 2, the transmission shaft 4 rotates to drive the crushing blade 5 to rotate and crush the flocculant to ensure uniform flocculant particles. Then, the rotating shaft 6 rotates to drive the vibration cam 7 to start rotating, and the vibration cam 7 beats and vibrates the elastic sieve plate 3, so that the flocculant uniformly falls from the elastic sieve plate 3. The bidirectional reciprocating lead screw 9 rotates to drive the scraping plate 8 to move reciprocally, and the limiting rod limits the scraping plate 8. The flocculant falling on the bottom of the inner wall of the dosing tank 2 is dropped from the discharge hole by the scraping plate 8, so that the flocculant is uniformly dropped into the water as a whole, thereby ensuring the consistency of the sufficient dissolution time and improving the adaptability of water treatment.

[0026] Further, as Figure 1 , Figure 3 and Figure 4As shown in the figure, motor chambers 10 and transmission chambers 11 are provided on both sides of the dosing tank 2; an in-built motor 12 is fixedly connected inside the motor chamber 10 through a motor block; the output shaft of the in-built motor 12 is fixedly connected to one end of a bidirectional reciprocating lead screw 9 through a coupling; one ends of the rotating shaft 6 and the bidirectional reciprocating lead screw 9 both penetrate through the dosing tank 2 and extend into the transmission chamber 11; transmission belt pulleys 13 are fixedly connected to one ends of the rotating shaft 6 and the bidirectional reciprocating lead screw 9 located inside the transmission chamber 11; the number of the rotating shafts 6 is set to two; the number of the transmission belt pulleys 13 is set to three, and the surfaces of the three transmission belt pulleys 13 are connected by belt transmission; a mixing tank 14 is fixedly connected to the top of the base 1; a rotating clamping shaft 15 is rotatably connected to the bottom of the inner wall of the mixing tank 14; a stirring impeller 16 is fixedly connected to the surface of the rotating clamping shaft 15; one end of the transmission shaft 4 penetrates through the dosing tank 2 in sequence and extends into the dosing tank 2; the surface of the dosing tank 2 is clamped with the top of the mixing tank 14; a hexagonal clamping shaft 17 is fixedly connected to one end of the transmission shaft 4 located inside the mixing tank 14; a hexagonal clamping groove 18 adapted to the hexagonal clamping shaft 17 is provided on the surface of the rotating clamping shaft 15. During operation, the in-built motor 12 is arranged in the motor chamber 10. When the in-built motor 12 works, it drives the bidirectional reciprocating lead screw 9 to start rotating through the output shaft. While the bidirectional reciprocating lead screw 9 rotates to drive the two scraping plates 8 to make reciprocating movements, it cooperates with the transmission belt pulleys 13 and the belt to drive the two rotating shafts 6 to start rotating. The rotation of the rotating shaft 6 drives the vibration cam 7 to rotate to achieve the effect of slapping the elastic sieve plate 3. In addition, when the transmission shaft 4 rotates to drive the crushing blades 5 to rotate, it also drives the hexagonal clamping shaft 17 to start rotating. The hexagonal clamping shaft 17 cooperates with the hexagonal clamping groove 18 to drive the rotating clamping shaft 15 to rotate, and then drives the stirring impeller 16 to start rotating, stirring during the mixing of the flocculant and water, accelerating the mixing time and the mixing uniformity, and improving the adaptability of use.

[0027] Further, as Figure 1 and Figure 2 shown, a motor cylinder 19 is fixedly connected to the top of the dosing tank 2; an upper motor 20 is fixedly connected inside the motor cylinder 19; the output shaft of the upper motor 20 is fixedly connected to the top end of the transmission shaft 4 through a coupling. During operation, the motor cylinder 19 is fixed to the top of the dosing tank 2, the upper motor 20 is installed inside the motor cylinder 19, and when the upper motor 20 works, it drives the transmission shaft 4 to start rotating through the output shaft to achieve the effects of the rotation and crushing of the crushing blades 5 and the rotation and stirring of the stirring impeller 16, improving the efficiency of water treatment.

[0028] Working principle: Since the above patent provides a flocculant dosing device, as the flocculant is a granular solid, when dosing, the flocculant is directly mixed and then introduced into the sewage for water purification. However, this dosing method cannot ensure that the flocculant is evenly scattered into the water, resulting in insufficient utilization of the flocculant. Moreover, the sizes and shapes of the dosed flocculants are different, so the dissolution times in water are inconsistent, and it is difficult to ensure the water purification efficiency. During operation, the elastic sieve plate 3 is fixed inside the dosing tank 2. The transmission shaft 4 rotates to drive the crushing blade 5 to rotate and crush the flocculant, ensuring that the flocculant particles are uniform. Then, the rotating shaft 6 rotates to drive the vibration cam 7 to start rotating. The vibration cam 7 impacts and vibrates the elastic sieve plate 3, causing the flocculant to uniformly fall from the elastic sieve plate 3. The bidirectional reciprocating lead screw 9 rotates to drive the scraping plate 8 to move reciprocally. The limit rod limits the scraping plate 8, and the scraping plate 8 causes the flocculant that has fallen on the bottom inner wall of the dosing tank 2 to fall from the discharge hole, enabling the flocculant to uniformly fall into the water as a whole, thereby ensuring the consistency of the sufficient dissolution time and improving the adaptability of water treatment. The built-in motor 12 is arranged inside the motor chamber 10. When the built-in motor 12 operates, it drives the bidirectional reciprocating lead screw 9 to start rotating through the output shaft. While the bidirectional reciprocating lead screw 9 rotates to drive the two scraping plates 8 to move reciprocally, it cooperates with the belt pulley 13 and the belt to drive the two rotating shafts 6 to start rotating. The rotating shaft 6 rotates to drive the vibration cam 7 to rotate, so as to achieve the effect of impacting the elastic sieve plate 3. In addition, when the transmission shaft 4 rotates to drive the crushing blade 5 to rotate, it also drives the hexagonal clamping shaft 17 to start rotating. The hexagonal clamping shaft 17 cooperates with the hexagonal card slot 18 to drive the rotating clamping shaft 15 to rotate, thereby driving the stirring impeller 16 to start rotating and stirring during the mixing of the flocculant and water, accelerating the mixing time and the mixing uniformity, and improving the adaptability of use. The motor cylinder 19 is fixed on the top of the dosing tank 2. The upper motor 20 is installed inside the motor cylinder 19. When the upper motor 20 operates, it drives the transmission shaft 4 to start rotating through the output shaft, so as to achieve the effects of the crushing blade 5 rotating for crushing and the stirring impeller 16 rotating for stirring, improving the efficiency of water treatment. By setting the dosing tank 2 and arranging the elastic sieve plate 3 inside the dosing tank 2, the transmission shaft 4 drives the crushing blade 5 to crush the flocculant, ensuring that the shape and size of each flocculant are the same. Then, the rotating shaft 6 drives the vibration cam 7 to rotate to impact and vibrate the elastic sieve plate 3, causing the crushed flocculant to uniformly fall from the surface of the elastic sieve plate 3. Finally, the scraping plate 8 moves reciprocally as the bidirectional reciprocating lead screw 9 rotates, and the flocculant that has fallen on the bottom inner wall of the dosing tank 2 uniformly falls from the discharge hole, enabling the flocculant to uniformly fall into the water as a whole, thereby ensuring the consistency of the sufficient dissolution time and improving the adaptability of water treatment.
