Description

Technical Field

[0001] The utility model relates to the technical field of circulating water dosing equipment, and more specifically to an intelligent dosing device for a circulating water system. Background Art

[0002] There are two main types of circulating water: industrial and household. The main purpose of both is to save water. During the circulation process of circulating water, it is necessary to treat it with chemicals. Chemical treatment is a commonly used dosing treatment measure in existing circulating water treatment, that is, different treatment chemicals are used according to different circulating water.

[0003] The shortcomings of the prior art: the existing dosing device cannot ensure the full mixing of the agent added to the circulating water when in use. When adding the agent, the agent is easily adhered to the inner wall of the mixing barrel, which makes the concentration of the agent added to the circulating water lower, which is not conducive to the treatment of the circulating water. Utility Model Content

[0006] Preferably, the mixing barrel comprises a barrel body, a support is fixedly connected to the bottom of the barrel body, and a barrel cover is fixedly connected to the top of the barrel body.

[0007] Preferably, the controller comprises a control body, a display screen is provided on the front side of the control body, and a button is fixedly connected to the front side of the control body.

[0008] Preferably, the water inlet pipe comprises a first tube body, and a liquid flow meter is fixedly connected to the outer side of the first tube body.

[0009] Preferably, the medicine storage box comprises a box body, a connecting column is fixedly connected to the bottom of the box body, a medicine outlet pipe is fixedly connected to the middle of the bottom of the box body, and a variable frequency metering pump is fixedly connected to the outer side of the medicine outlet pipe.

[0010] Preferably, the water outlet pipe comprises a second pipe body, and a concentration measuring meter is fixedly connected to the top of the second pipe body.

[0011] Technical effects and advantages of the utility model:

[0012] The utility model is provided with a water outlet pipe and a stirring device, which is conducive to fully mixing the medicine with the circulating water. When in use, the water inlet pipe and the water outlet pipe are connected between the loop of the circulating water. The controller is used to set the amount of medicine sprayed by the variable frequency metering pump for the circulating water with different flow rates. After the setting is completed, the circulating water enters the stirring barrel through the water inlet pipe, and the flow rate of the circulating water is detected under the action of the liquid flow meter. At the same time, the variable frequency metering pump will spray different doses of medicine into the inside of the stirring barrel according to the flow rate. The variable speed motor is started so that the rotating shaft can drive the fixed column to rotate, and then the telescopic barrel and the scraper are rotated, so that the circulating water and the medicine are mixed. At this time, the rotation of the variable speed motor is in a low speed state, and the telescopic barrel and the scraper are extended under the action of centrifugal force. The telescopic barrel will move on the outside of the fixed column, and the scraper will not contact the inner wall of the mixing barrel. Then the circulating water with the added agent will flow out through the outlet pipe, and then flow into the mixing barrel through the inlet pipe. When the circulating water passes through the outlet pipe, the concentration meter will detect the concentration of the agent in the circulating water. When the concentration is too low, it will control the variable speed motor to be in a high-speed state, so that the telescopic barrel moves on the outside of the fixed column. Compared with the low-speed rotation, its centrifugal force is larger, so that the scraper can contact the inner wall of the mixing barrel, and through the rotation, the residual agent on the inner wall can be scraped off and mixed with the circulating water, ensuring that the agent and the circulating water are mixed more completely, and the circulating water treatment will not be incomplete due to the agent sticking to the inner wall of the mixing barrel.

The variable speed motor 401 can rotate at a variable speed. When it is in a low-speed state, the scraper 406 will not contact the inner wall of the mixing barrel 1 under the action of centrifugal force. When it is in a high-speed state, the scraper 406 will be released from the mixing barrel 1, and the medicine adhering to the inner wall of the mixing barrel 1 can be scraped off and mixed by rotation, thereby ensuring that the medicine and the circulating water are mixed more completely, and the circulating water treatment will not be incomplete due to the medicine adhering to the inner wall of the mixing barrel 1.

[0019] Furthermore, the mixing barrel 1 includes a barrel body 101 , a support 102 is fixedly connected to the bottom of the barrel body 101 , and a barrel cover 103 is fixedly connected to the top of the barrel body 101 . The mixing barrel 1 is used to store circulating water.

[0024] The working principle of the utility model is as follows: when in use, the water inlet pipe 3 and the water outlet pipe 6 are connected between the loop of the circulating water, and the controller 2 is used to set the amount of medicine sprayed by the variable frequency metering pump 503 for the circulating water with different flow rates. After the setting is completed, the circulating water enters the mixing barrel 1 through the water inlet pipe 3, and the flow rate of the circulating water is detected under the action of the liquid flow meter 302.

When the circulating water passes through the outlet pipe 6, the concentration meter 602 will detect the concentration of the medicine in the circulating water. When the concentration is too low, it will control the variable speed motor 401 to be in a high-speed state, so that the telescopic barrel 403 moves on the outside of the fixed column 405. Compared with the low-speed rotation, its centrifugal force is larger, so that the scraper 406 can contact the inner wall of the mixing barrel 1, and through the rotation, the medicine remaining on the inner wall can be scraped off and mixed with the circulating water, ensuring that the medicine and the circulating water are mixed more completely, and the circulating water treatment will not be incomplete due to its adhesion to the inner wall of the mixing barrel 1.
