Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration type chemical dosing tank. Background Art

[0002] The chemical dosing device in sewage treatment equipment is a device used to add chemical agents such as polyaluminum chloride (PAC) and polyacrylamide (PAM) to sewage, so as to promote chemical reactions in the sewage treatment process, remove pollutants, and improve water quality. The chemical dosing device is an important part of sewage treatment equipment, and its reasonable design and operation are crucial for ensuring the sewage treatment effect and achieving up-to-standard discharge.

[0003] For example, Chinese Patent Application Publication No. CN219907058U discloses a stirring device for a chemical dosing tank. The device includes a motor, and a stirring tooth is installed at the bottom end of the motor. The motor and the stirring tooth together form a mixing structure for stirring the chemical agent in the dosing tank. In addition, a self-cleaning device is provided, which can quickly spray and clean the stirring tooth by spraying water flow.

[0004] However, the above device still has certain defects: 1. Rotating and stirring the chemical agent through a fan blade or a toothed structure is likely to cause uneven stirring, which further affects the flocculation and precipitation effect of sewage; 2. The undissolved chemical agent sinks to the bottom of the tank to form a sediment layer, which is likely to cause the motor to be overloaded and damaged. At the same time, there is a risk of gas poisoning for operators when cleaning the sediment layer. Summary of the Utility Model

[0005] The utility model provides an aeration type chemical dosing tank to solve the technical problem that uneven mixing of chemical agents in the sewage treatment process leads to the sinking of chemical agents to the bottom, thereby affecting the subsequent sewage treatment effect.

[0008] Its beneficial effects are as follows: By arranging an aeration disc at the bottom of the chemical dosing tank, the microbubbles generated by the aeration disc enhance the mixing effect of the chemicals, significantly improving the flocculation and sedimentation effect of the sewage, thereby reducing the filtration pressure of the subsequent equipment; at the same time, the phenomenon of chemical sedimentation is reduced, and there is no need to clean the chemical dosing tank regularly, thus reducing the risk for operators to clean the chemical dosing tank.

[0009] Further, the box body is a rectangular box, and there are two partitions extending front and rear on the left and right inside the box body. The partitions divide the box body into a first compartment, a second compartment, and a third compartment from right to left in sequence.

[0010] Further, the right partition is higher than the left partition to prevent the backflow of the mixed liquid.

[0011] Further, the aeration disc is a circular disc, and the first compartment, the second compartment, and the third compartment all have an aeration disc; there are multiple air holes on the aeration disc, and the air holes are used to release air into the box body in the form of microbubbles and prevent water from flowing back into the ventilation pipe.

[0012] Further, the chemical dosing port is a funnel-shaped structure located at the top of the box body and above the first compartment.

[0013] Further, a water level detection device is arranged inside the box body on the left side of the third compartment, which is used to detect the water level to control the start and stop of the chemical dosing port and the water injection port.

[0014] Its beneficial effects are as follows: By arranging a water level detection device on the left side of the third compartment, the water injection port and the chemical dosing port are controlled to start and stop automatically according to the water level situation, improving the operation convenience.

[0015] Further, a water pump is provided at the bottom of the third compartment, and the water pump is connected to the water outlet through a provided pipeline to pump out the mixed liquid.

[0016] The beneficial effects of the aeration type chemical dosing tank provided by the utility model are as follows:

[0017] 1. By arranging an aeration disc at the bottom of the chemical dosing tank, the microbubbles generated by the aeration disc enhance the mixing effect of the chemicals, significantly improving the flocculation and sedimentation effect of the sewage, thereby reducing the filtration pressure of the subsequent equipment; at the same time, the phenomenon of chemical sedimentation is reduced, and there is no need to clean the chemical dosing tank regularly, thus reducing the risk for operators to clean the chemical dosing tank.

[0018] 2. By arranging a water level detection device on the left side of the third compartment, the water injection port and the chemical dosing port are controlled to start and stop automatically according to the water level situation, improving the operation convenience.

Those skilled in the art should know that the embodiments described below are a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0025] The main concept of the present utility model is to make the chemical agent and water surge under the action of microbubbles by arranging an aeration disk 5 at the bottom of the chemical dosing tank, thereby enhancing the mixing effect of the chemical agent and improving the flocculation and sedimentation effect of sewage; at the same time, the phenomenon of the chemical agent sinking to the bottom is reduced, and there is no need to clean the chemical dosing tank regularly, thereby reducing the risk for operators to clean the chemical dosing tank.

[0026] After introducing the basic principle of the present utility model, the various non-restrictive embodiments of the present utility model will be specifically introduced below. The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0027] Next, with reference to several representative embodiments of the present utility model, the principles and spirits of the present utility model will be elaborated in detail.

[0028] Embodiment 1 of an aeration type chemical dosing tank provided by the present utility model:

[0029] As Figures 1 to 2As shown in the figure, the device includes a box body 1, which is a rectangular box. The upper end of the box body 1 has a funnel-shaped chemical addition port 2, and the upper end of one side of the box body 1 has a tubular water injection port 3. The side where the water injection port 3 is located is defined as the right side, and the upper end of the left side of the box body 1 has a water outlet 4. Inside the box body 1, there are two partitions 11 extending forward and backward from left to right. The right partition 11 is higher than the left partition 11 to prevent the backflow of the mixed liquid. The partitions 11 divide the box body 1 into a first compartment 12, a second compartment 13, and a third compartment 14 from right to left in sequence to improve the mixing effect of the chemical agent and water.

[0030] The bottom of the box body 1 is provided with an aeration device 9. The aeration device 9 includes a plurality of aeration discs 5 horizontally arranged in each compartment. The aeration disc 5 is a circular disc, and the aeration disc 5 is provided with a plurality of air holes 51. Under the action of the lower pressure, the air holes 51 can release air into the box body 1 in the form of microbubbles. At the same time, the air holes 51 are self-closing hole structures, which can prevent water from flowing back into the ventilation pipe 7.

[0031] A ventilation pipe 7 is provided below the aeration disc 5. The left end of the ventilation pipe 7 is provided with an air compressor 6 outside the box body 1. The ventilation pipe 7 is used to connect the air compressor 6 and the aeration disc 5 to release air into the box body 1.

[0032] In addition, a water pump 42 is also provided at the bottom of the third compartment 14. The water pump 42 is connected to the water outlet 4 through a pipe 41 to output the mixed liquid to the outside. Two water level detection devices 8 are respectively provided at the upper and lower ends of the left side wall of the third compartment 14 to detect the water level to control the start and stop of the chemical addition port 2 and the water injection port 3.

[0033] During use, first, the chemical addition port 2 and the water injection port 3 add the chemical agent and water into the first compartment 12 according to a certain ratio. At this time, the air compressor 6 is turned on, so that the aeration disc 5 releases air into the box body 1 in the form of microbubbles. Under the mixing and stirring action of the bubbles, the chemical agent and water are initially mixed. At the same time, the chemical agent can be driven upward by the bubbles and surge in the water to avoid the chemical agent sinking to the bottom. After the first compartment 12 is filled, the mixed liquid overflows to the second compartment 13 and is further mixed in the second compartment 13. After the second compartment 13 is filled, it overflows to the third compartment 14. When the water level of the mixed liquid rises to the lower water level detection device 8, the water pump 42 starts to work and pumps out the mixed liquid for sewage treatment. When the water level in the third compartment 14 rises to the upper water level detection device 8, the chemical addition port 2 and the water injection port 3 stop working. When the water level in the third compartment 14 drops to the lower water level detection device 8, the water injection port 3 and the chemical addition port 2 start to work, and so on, to achieve continuous operation.

[0034] Embodiment 2 of an aeration type chemical addition tank provided by the present utility model:

[0035] The main difference from Embodiment 1 is that:

[0036] In Embodiment 1, the water outlet is arranged on the left side of the box body.
