Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, and more specifically, it relates to a chemical dosing structure for wastewater treatment. Background Art

[0002] Wastewater treatment refers to purifying wastewater to a certain extent through chemical treatment, filtration, precipitation, etc., so that it can be reused again to achieve the purpose of saving water resources. Among them, chemical treatment is to add specific chemicals to the wastewater to precipitate some substances in the water, and then treat the precipitated substances. However, for some chemical agents, the existing method of directly pouring the chemical agent into the wastewater may cause the situation that the chemical agent cannot fully react during the sinking process, resulting in the accumulation of the chemical agent, so that some chemical agents cannot fully contact the wastewater, affecting the efficiency of wastewater treatment.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0011] In summary, the utility model has the following beneficial effects: The medicament will spiral down along the spiral blade, delaying the falling speed of the medicament, increasing the contact time between the medicament and the wastewater before accumulation, improving the efficiency of wastewater treatment. When the medicament descends on the spiral blade, part of the medicament slides along the spiral blade and part of the medicament directly falls from the orifice, avoiding the accumulation of the medicament at the coil part on the random selection blade, improving the utilization rate of the inner cavity space, and further increasing the contact area between the medicament and the wastewater.

[0014] The following combines the drawings and embodiments to describe the utility model in detail.

[0015] Embodiment: A wastewater treatment chemical adding structure, as Figure 1 shown, includes a feed pipe 1. The bottom end of the feed pipe 1 is fixedly connected with a housing. An inner cavity 3 is opened in the housing. A spiral blade 4 is arranged in the inner cavity 3. A plurality of through holes 5 are arranged through the side wall of the housing. The plurality of through holes 5 are linearly arranged along the length direction of the housing. A plurality of orifices 11 are arranged vertically through the spiral blade 4.

[0016] Specifically, the outer edge of the spiral blade 4 fits the inner wall of the housing. The external wastewater enters the inner cavity 3 through the through holes 5. The medicament enters the inner cavity 3 from top to bottom through the feed pipe 1. The wastewater and the medicament come into contact in the inner cavity 3. When the reaction speed between the medicament and the wastewater is slow, the remaining medicament will spiral down along the spiral blade 4, delaying the falling speed of the medicament, increasing the contact time between the medicament and the wastewater before accumulation, and improving the efficiency of wastewater treatment. Two orifices 11 are arranged on each circle of the spiral blade 4. When the medicament descends on the spiral blade 4, part of the medicament slides along the spiral blade 4 and part of the medicament directly falls from the orifices 11, avoiding the accumulation of the medicament at the coil part on the random selection blade, improving the utilization rate of the inner cavity 3 space, and further increasing the contact area between the medicament and the wastewater.

[0017] Such as Figure 1As shown in the figure, an air inlet pipe 6 is penetrated through the side wall of the housing. One end of the air inlet pipe 6 located inside the inner cavity 3 is fixedly connected with an air delivery pipe 7. The air delivery pipe 7 is coaxially arranged with the housing. A plurality of air injection holes 8 are penetrated through the side wall of the air delivery pipe 7. The air injection holes 8 are linearly arranged along the length direction of the air delivery pipe 7. The air injection holes 8 and the through holes 5 are respectively located on both sides of the air delivery pipe 7. The housing includes a top cover 2 and a pipe body 9. The top end of the top cover 2 is detachably connected with the feed pipe 1. The bottom end of the top cover 2 is detachably connected with the pipe body 9. The air inlet pipe 6 is fixedly connected with the top cover 2. The spiral blade 4 is fixedly connected with the air delivery pipe 7. A blanking hole 10 is formed on the bottom surface of the pipe body 9.

[0018] Specifically, the bottom end of the feed pipe 1 is inserted into the bottom end of the top cover 2. The air inlet pipe 6 is welded to the top cover 2. The axis of the air inlet pipe 6 is perpendicular to the axis of the air delivery pipe 7. The air inlet pipe 6 and the air delivery pipe 7 are integrally formed. The spiral blade 4 is welded to the air delivery pipe 7. When the medicament descends on the spiral blade 4, gas is input into the air delivery pipe 7 through the air inlet pipe 6. The gas gushes out from the air injection holes 8, so that a water flow is generated in the inner cavity 3, stirring the medicament and the wastewater. While improving the reaction speed between the medicament and the wastewater, it can also reduce the possibility of the medicament being blocked in the pipe body 9. The air injection holes 8 and the through holes 5 are respectively on both sides of the air delivery pipe 7. The air flow is intermittently input through the air inlet pipe 6, so that the gushing air flow drives the water flow and part of the medicament to move towards the direction close to the through hole 5, enhancing the mass exchange between the inner cavity 3 and the outside. The bottom end of the top cover 2 is threadedly connected with the top end of the pipe body 9. Through the detachable connection between the pipe body 9 and the top cover 2, when cleaning is required, the pipe body 9 is disassembled to expose the spiral blade 4, which is convenient for cleaning the spiral blade 4. The blanking hole 10 located on the bottom surface of the pipe body 9 ensures that the medicament that has not been completely reacted can continue to fall, avoiding the deposition of the medicament at the bottom of the pipe body 9.

[0019] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as the protection scope of the present invention.
