Description

Technical Field

[0001] The utility model relates to the technical field of drinking water production equipment, in particular to ozone disinfection equipment for drinking water production. Background Art

[0002] When bottled water is produced, ozone is needed to disinfect and deodorize the water. However, when the ozone disinfection device in the prior art is used, the contact rate between water and ozone is low, and the ozone dissolution rate is low, which affects the disinfection effect of the water. After ozone comes into contact with drinking water, it is easy to form bubbles and they will merge with each other to form large bubbles during the rising process. There is a problem that large bubbles rise faster, resulting in poor disinfection and purification effects.

[0003] At present, a stirring roller is set in the disinfection equipment to ensure that the bubbles are eliminated during the disinfection process. However, the stirring roller cannot ensure that all bubbles are eliminated. When the bubbles that are not eliminated float to the top of the water surface due to buoyancy and then break, the ozone is at the top of the water surface and cannot be effectively utilized, resulting in a poor disinfection effect. For this reason, we propose an ozone disinfection equipment for drinking water production. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an ozone disinfection device for drinking water production, comprising a disinfection tank 1 and an ozone generator 2 arranged on the left side of the disinfection tank 1, an auxiliary mechanism 3 is arranged inside the disinfection tank 1, and the auxiliary mechanism 3 includes: a motor 31, a connecting pipe 32, an air intake sleeve 33, a U-shaped stirring shaft 34, an exhaust pipe 35, and a driven member 36.

[0023] The motor 31 is fixed at the bottom of the disinfection tank 1, and the output shaft of the motor 31 passes through the bottom of the disinfection tank 1 and is rotatably connected to the disinfection tank 1. A sealed bearing is provided at the position where the output shaft of the motor 31 is connected to the disinfection tank 1. The bottom of the connecting pipe 32 is fixed to the top of the output shaft of the motor 31. An air intake sleeve 33 is fixed on the inner wall of the disinfection tank 1. The top of the connecting pipe 32 is rotatably mounted on the inner side of the air intake sleeve 33 through a sealed bearing. A U-shaped stirring shaft 34 is fixed on the surface of the connecting pipe 32. An exhaust pipe 35 passes through the surface of the connecting pipe 32 and is fixed to the exhaust pipe 35. A follower 36 for assisting gas circulation is provided inside the connecting pipe 32 and the disinfection tank 1. When ozone enters the disinfection tank 1, it enters the connecting pipe 32 through the air intake sleeve 33 and is then discharged from the exhaust pipe 35, so that the ozone can be at the bottom of the drinking water in the disinfection tank 1 in the initial stage, so that the ozone can better contact with the drinking water, thereby achieving better disinfection, and the U-shaped stirring shaft 34 rotating with the connecting pipe 32 can eliminate bubbles in the drinking water.

[0024] The driven member 36 includes a connecting rod 361, the bottom of which is fixed to the inner wall of the connecting pipe 32, an impeller 362 is fixed to the top of the connecting rod 361, a blocking ring 363 is fixed to the inner wall of the disinfection tank 1, the blocking ring 363 is penetrated by and fixedly connected to the connecting pipe 364, the connecting pipe 364 penetrates the air inlet sleeve 33 and is fixedly connected to the air inlet sleeve 33, when the connecting pipe 32 drives the U-shaped stirring shaft 34 to rotate, the drinking water in the disinfection tank 1 is acted upon by centrifugal force, and the bubbles formed by ozone in the drinking water are moved to the side of the tank wall close to the disinfection tank 1 by the centrifugal force, and when the bubbles are not penetrated by the U-shaped stirring shaft 34, the drinking water in the disinfection tank 1 is moved to the side of the tank wall close to the disinfection tank 1 by the centrifugal force. The bubbles broken by the stirring shaft 34 are moved to the top of the drinking water due to buoyancy, and the ozone is between the blocking ring 363 and the tank wall of the disinfection tank 1. At this time, the ozone re-enters the air inlet sleeve 33 through the connecting pipe 364 and circulates again through the connecting pipe 32, avoiding the ozone being at the top of the inside of the disinfection tank 1 and being unable to effectively disinfect the drinking water. When the connecting pipe 32 rotates, the connecting pipe 32 drives the connecting rod 361 and the impeller 362 to rotate. When the impeller 362 rotates, the ozone can be pumped, so that the ozone moves from top to bottom in the connecting pipe 32, avoiding the ozone entering the connecting pipe 364 when entering the air inlet sleeve 33.

[0025] A water inlet valve 4 and a drain valve 5 are provided on the right side of the disinfection tank 1. Drinking water can be discharged into the disinfection tank 1 through the water inlet valve 4, and the drinking water that has been disinfected in the disinfection tank 1 can be discharged by opening the drain valve 5. The ozone generator 2 and the disinfection tank 1 are connected through an air inlet pipe 6. The ozone generated by the ozone generator 2 enters the disinfection tank 1 through the air inlet pipe 6 and then enters the air inlet sleeve 33. A pressure sensor 7 and an exhaust valve 8 are provided on the disinfection tank 1. The pressure sensor 7 can monitor the pressure in the disinfection tank 1. When the pressure is too high, the pressure sensor 7 is connected to the exhaust valve 8, and the pressure sensor 7 can open the exhaust valve 8 to exhaust gas to avoid excessive pressure in the disinfection tank 1.

[0026] Based on the above embodiment, the water inlet valve 4 is opened, and drinking water is poured into the disinfection tank 1. Since the tank body is transparent, the drinking water in the disinfection tank 1 is observed until the blocking ring 363 is submerged in the water.

[0027] Start the ozone generator 2 and the motor 31. The ozone generated by the ozone generator 2 enters the disinfection tank 1 through the air inlet pipe 6 and then enters the air inlet sleeve 33. At this time, the motor 31 drives the connecting pipe 32 to rotate, and the connecting pipe 32 drives the connecting rod 361 and the impeller 362 to rotate. When the impeller 362 rotates, the ozone can be pumped, so that the ozone moves from top to bottom in the connecting pipe 32, avoiding the ozone from entering the connecting pipe 364 when entering the air inlet sleeve 33.

[0028] After entering the connecting pipe 32, the ozone is discharged through the exhaust pipe 35, so that the ozone can be at the bottom of the drinking water in the disinfection tank 1 in the initial stage, so that the ozone can better contact the drinking water, thereby achieving better disinfection. The U-shaped stirring shaft 34 that rotates with the connecting pipe 32 can eliminate bubbles in the drinking water. When the connecting pipe 32 drives the U-shaped stirring shaft 34 to rotate, the drinking water inside the disinfection tank 1 is affected by centrifugal force, and the bubbles formed by the ozone in the drinking water are moved to the side close to the tank wall of the disinfection tank 1 by the centrifugal force. When the bubbles that are not broken by the U-shaped stirring shaft 34 are moved to the top of the drinking water by buoyancy, the ozone is between the blocking ring 363 and the tank wall of the disinfection tank 1. At this time, the ozone re-enters the air inlet sleeve 33 through the connecting pipe 364 and circulates again through the connecting pipe 32, avoiding the ozone being at the top of the inside of the disinfection tank 1 and failing to effectively disinfect the drinking water.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
