Description

Technical Field

[0001] The utility model relates to the technical field of backflow water treatment, in particular to a backflow water collection and treatment device. Background Art

[0002] At present, the backflow preventers of most high-level biosafety laboratory projects are set outside the protection zone: mostly on the technical interlayer, in the pipe well and in the water supply pump room, etc. According to the working principle of the backflow preventer (pressure reduction type and low resistance), when the medium backflow occurs, the backflow preventer will open the drainage cavity to discharge the backflow medium. As for the backflow water in the protection zone, the current problems are as follows:

[0003] 1. If drainage is not considered, the dripping water or a small amount of drainage will inevitably fall to the ground, affecting sanitary conditions and posing the risk of leakage of biological pathogens;

[0004] 2. If the drainage pipe is designed to be connected to the live toxic wastewater device, indirect drainage must be used according to the current specifications, because the end of the drainage pipe is connected to the live toxic wastewater tank that stores a large amount of toxic wastewater, so the risk of leakage of biological pathogens in the drainage pipe will be greater;

[0005] Therefore, most of the current high-level biosafety laboratory projects do not have corresponding drainage measures at the locations where backflow preventers are set. The backflow water can only leak to the ground at the corresponding location and evaporate naturally. To this end, in response to the above problems, a backflow water collection and treatment device is designed to better meet actual use needs. Utility Model Content

[0025] The air partition device 4 is composed of a box body 41 and a float 42, and the box body 41 is connected to the S-shaped water trap 3 and the water inlet pipe 5, and a float 42 is arranged in the box body 41, and the float 42 cooperates with the lower opening of the box body 41 to achieve a sealing effect;

[0026] When using the backflow water collection and treatment device, if Figure 1 and Figure 2 As shown, water splashed by the backflow preventer is collected through the water inlet pipe 5. At this time, the water enters the box body 41. With the buoyancy of the float ball 42 and the water, the float ball 42 can be separated from the lower end opening of the box body 41, and the sealing effect is released. At this time, the water enters the collection box 1 through the lower end opening of the box body 41 to be collected and stored, which is convenient for subsequent processing. The water level in the collection box 1 can be conveniently observed through the liquid level meter 2. When there is no water in the box body 41, the float ball 42 can be sealed with the lower end opening of the box body 41 under the gravity of the float ball 42, so as to prevent the exhaust gas in the collection box 1 from overflowing through the box body 41.

[0027] The automatic dosing device 8 is composed of a medicine box 81, a first motor 82, a rotating shaft 83, a stirring blade 84 and a sealing plug 85. The first motor 82 is fixed to the upper end surface of the medicine box 81, and the rotating shaft 83 is fixed to the output end of the first motor 82. The rotating shaft 83 is connected to the medicine box 81 by a bearing. At the same time, the stirring blade 84 is evenly fixed on the rotating shaft 83. The lower end of the medicine box 81 is connected to a sealing plug 85; a disc 831 is fixed to the lower end of the rotating shaft 83 that penetrates the medicine box 81, and a convex block 832 with a semicircular cross-section is fixed symmetrically on the upper end surface of the disc 831; the sealing plug 85 is connected to the medicine box 81. The lower end opening of the box 81 is nested to achieve a sealing effect, and the sealing plug 85 is symmetrically distributed about the center line of the medicine box 81; a vertical rod 851 is also vertically fixed to the lower end surface of the sealing plug 85, and the vertical rod 851 contacts the protrusion 832 and can slide; one end of a spring 86 is fixed to the vertical rod 851, and the other end of the spring 86 is fixed to the medicine box 81; the stirring device 9 is composed of a second motor 91 and a stirring rod 92, and the second motor 91 is fixed to the collection box 1, and the stirring rod 92 is fixed to the output shaft of the second motor 91, and the stirring rod 92 is arranged in the collection box 1;

When the rotating shaft 83 rotates, the disc 831 and the protrusion 832 are driven to rotate at the same time. When the protrusion 832 contacts and slides with the arc surface at the lower end of the vertical rod 851, the vertical rod 851 is forced to move upward to cause the spring 86 to contract, thereby separating the sealing plug 85 from the lower end opening of the medicine box 81, releasing the sealing effect, and facilitating the disinfectant in the medicine box 81 to fall onto the disc 831 through the lower end opening of the medicine box 81. At this time, the centrifugal force of the disc 831 can make The disinfectant splashes all around so that the disinfectant can evenly contact the wastewater in the collection box 1, and cooperates with the second motor 91 to drive the stirring rod 92 for stirring, which can ensure the uniformity of the mixing of the disinfectant and the wastewater in the collection box 1. When the protrusion 832 is separated from the vertical rod 851, the sealing plug 85 can be reset and nested with the lower opening of the medicine box 81 under the action of the spring 86. According to the above principle, the intermittent automatic addition of disinfectant can be realized to avoid waste caused by excessive addition of disinfectant.
