Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment devices, in particular to a chemical dosing sewage treatment device for sewage treatment. Background Technique

[0002] In the process of sewage treatment, physical, chemical and biological methods are usually used to purify the water quality to meet the discharge or reuse standards. Among them, chemical treatment involves adding various chemicals to the sewage, such as coagulants, flocculants and disinfectants, etc., to remove pollutants.

[0003] In order to ensure that these chemicals can be evenly dispersed and fully play their roles, the chemicals are generally pre-mixed with water in a special chemical dosing tank. The traditional chemical dosing tank is equipped with a stirring mechanism to achieve effective mixing of the chemicals and water by rotating and stirring. However, when different types of chemicals need to be continuously added, the single-chamber design of the traditional chemical dosing tank may cause the residue of the previous chemical to be mixed with the new chemical, thus affecting the treatment effect. In addition, in order to prevent cross-contamination, the chemical dosing tank needs to be thoroughly cleaned before each chemical replacement, and it is necessary to ensure that the liquid medicine in the chemical dosing tank is completely discharged. However, this method may cause the inside of the chemical dosing tank to be unable to be cleaned in time, resulting in a reduction in work efficiency.

[0004] Therefore, the utility model proposes a chemical dosing sewage treatment device for sewage treatment. Content of the Utility Model

[0005] In order to solve the deficiencies of the prior art, the utility model proposes a chemical dosing sewage treatment device for sewage treatment, which is convenient for cleaning the chemical dosing tank and effectively improves work efficiency.

[0006] In order to achieve the above object, the utility model adopts the following technical solutions: A chemical dosing sewage treatment device for sewage treatment includes a chemical dosing tank and a liquid injection port arranged at the top of the chemical dosing tank. A storage tank communicated with the chemical dosing tank is arranged at the bottom of the chemical dosing tank. A liquid outlet is opened at the bottom of the chemical dosing tank. There are four liquid outlets in total, and the four liquid outlets are annularly distributed at equal intervals. Two of the four liquid outlets are in a group, and liquid outlet assemblies are arranged on both groups of liquid outlets;

[0007] The liquid outlet assembly includes a connecting rod. The connecting rod is arranged below the chemical dosing tank. Guide liquid seats are arranged at both ends of the connecting rod. A guide liquid groove is opened on the guide liquid seat. The two guide liquid seats are respectively slidably connected in the liquid outlet. A driving plate is arranged on the connecting rod;

[0008] Electric push rods are arranged at both ends of the chemical dosing tank. The bottom of the electric push rod penetrates through the chemical dosing tank and is connected with the driving plate.

[0009] Further, a rotating shaft is rotatably connected to the center inside the chemical dosing tank. A stirring impeller is arranged on the rotating shaft. A driving motor for driving the rotating shaft to rotate is arranged at the bottom of the chemical dosing tank. A protective cover is arranged at the top of the chemical dosing tank, and the liquid injection port is located at the top of the protective cover.

[0010] Further, limit seats are arranged at the bottom of the chemical dosing tank at both ends where the driving plates are close to each other. The driving plates are slidably connected in the limit seats, and springs are arranged between the limit seats and the driving plates.

[0011] Further, an annular partition is arranged on the storage tank outside the driving motor. The driving motor is located inside the annular partition. Partition plates are arranged on both sides of the annular partition. The storage tank is provided with two liquid storage cavities through the annular partition and the partition plates.

[0012] Further, liquid outlet pipes are fixedly communicated with the bottoms of the two liquid storage cavities at the bottom of the storage tank.

[0013] Further, a movable opening is formed in the storage tank at the position of the driving plate, and the width of the movable opening is greater than the width of the driving plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, through the design of the liquid outlet assembly, after the chemical agent in the chemical dosing tank is mixed with water, when one of the electric push rods is turned on, it drives the corresponding liquid guiding seat to move downward, so that the liquid outlet assembly is misaligned and separated from the bottom of the chemical dosing tank. At this time, the liquid medicine can be discharged into the lower liquid storage cavity through the liquid guiding groove for storage. When the mixed liquid enters one of the cavities, the electric push rod is turned on to drive the liquid outlet assembly to move upward to block the liquid outlet again. At this time, clean water can be injected into the chemical dosing tank to clean the inside of the chemical dosing tank to prevent chemical agent residue. The liquid used to clean the inside of the chemical dosing tank is introduced into the lower cavity through the other set of liquid outlet assemblies and discharged through the liquid outlet pipe. Compared with the traditional stirring cavity, this structure can effectively improve the working efficiency.

[0016] 2. In the present utility model, through the structural design of the stirring impeller, when the chemical agent and water in the chemical dosing tank are mixed, under the action of the stirring impeller, a vortex is generated inside the chemical dosing tank, thereby further improving the mixing effect. And when the bottom of the stirring impeller is in contact with the bottom of the chemical dosing tank, when the liquid medicine is discharged, under the continuous rotation of the stirring impeller, the chemical agent mixed liquid on the stirring impeller is thrown out in all directions under the action of centrifugal force and discharged into the designated cavity through the liquid outlet. Compared with the traditional stirring by a stirring roller, this method can reduce the residue of the liquid medicine in the chemical dosing tank, thereby improving the practicability of the device.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1-5As shown in the figure, the present utility model provides a technical solution: a chemical dosing sewage treatment device for sewage treatment, including a chemical dosing tank 1 and a liquid injection port 111 provided at the top of the chemical dosing tank 1. A storage tank 12 communicated with the chemical dosing tank 1 is provided at the bottom of the chemical dosing tank 1. An outlet 15 is opened at the bottom of the chemical dosing tank 1. There are four outlets 15 in total, and the four outlets 15 are evenly distributed in a circular pattern at equal intervals. Two of the four outlets 15 are in a group, and liquid outlet assemblies 2 are provided on both groups of outlets 15; the liquid outlet assembly 2 includes a connecting rod 21. The connecting rod 21 is provided below the chemical dosing tank 1. Guide seats 23 are provided at both ends of the connecting rod 21. The two guide seats 23 are respectively slidably connected in the outlet 15. A driving plate 22 is provided on the connecting rod 21. Electric push rods 16 are provided at both ends of the chemical dosing tank 1. The bottom of the electric push rod 16 penetrates through the chemical dosing tank 1 and is connected to the driving plate 22. An annular partition 121 is provided on the storage tank 12 outside the driving motor 18. Partition plates 122 are provided on both sides of the annular partition 121. The storage tank 12 is provided with two liquid storage cavities 124 through the annular partition 121 and the partition plates 122. Through the design of the liquid outlet assembly 2, after the chemical agent in the chemical dosing tank 1 is mixed with water, one of the electric push rods 16 is turned on to drive the corresponding guide seat 23 to move downward, so that the liquid outlet assembly 2 is misaligned and separated from the bottom of the chemical dosing tank 1. At this time, the liquid medicine can be discharged into the lower liquid storage cavity 124 for storage. When the mixed liquid enters one of the cavities, the electric push rod 16 is turned on to drive the liquid outlet assembly 2 to move upward to block the outlet 15 again. At this time, clean water can be injected into the chemical dosing tank 1 to clean the chemical dosing tank 1 to prevent chemical agent residue. The liquid used to clean the inside of the chemical dosing tank 1 is introduced into the lower cavity through the other set of liquid outlet assemblies 2 and discharged through the liquid outlet pipe 13, solving the technical problem of cleaning the inside of the chemical dosing tank 1 during chemical dosing.

[0027] Furthermore, as Figure 1 - Figure 3 shown: A rotating shaft 17 is rotatably connected to the center of the inside of the chemical dosing tank 1. A stirring impeller 14 is provided on the rotating shaft 17. A protective cover 11 is provided at the top of the chemical dosing tank 1. A liquid injection port 111 is opened at the top of the protective cover 11. A driving motor 18 is provided at the bottom of the chemical dosing tank 1. The output end of the driving motor 18 is connected to the rotating shaft 17. Through the structural design of the stirring impeller 14, when the chemical agent and water in the chemical dosing tank 1 are mixed, under the action of the stirring impeller 14, a vortex is generated inside the chemical dosing tank 1, thereby further improving the mixing effect. And when the bottom of the stirring impeller 14 is in contact with the bottom of the chemical dosing tank 1, when the liquid medicine is discharged, under the continuous rotation of the stirring impeller 14, the chemical agent mixed liquid on the stirring impeller 14 is thrown out in all directions under the action of centrifugal force and is discharged into the designated cavity through the outlet 15. Compared with the traditional stirring roller stirring, this method can reduce the residue of the liquid medicine in the chemical dosing tank 1, solving the technical problem of the residue of the liquid medicine inside the chemical dosing tank 1.

[0028] In order to prevent the driving plate 22 from tilting when the electric push rod 16 drives the driving plate 22 to move up and down, as shown in FIG. Figure 4 As shown: in the present scheme, a limit seat 19 is provided at the bottom of the medicine adding box 1 at one end where the driving plates 22 are close to each other, and the driving plate 22 is slidably connected in the limit seat 19, and a spring 191 is provided between the limit seat 19 and the driving plate 22. The limit seat 19 limits the driving plate 22 to prevent the driving plate 22 from tilting to one side during the process of the electric push rod 16 driving the driving plate 22 to be pressed down, causing the liquid guide seat 23 to be stuck and unable to move up and down. Under the action of the spring 191, when the liquid guide seat 23 moves up and down, the spring 191 assists in pressing down the driving plate 22 to ensure that the driving plate 22 does not tilt during displacement.

[0029] like Figure 2 As shown: in this solution, the bottom of the storage box 12 is located at the bottom of the two liquid storage cavities 124 and is fixedly connected with a liquid outlet pipe 13, through which the liquid in the two independent cavities is discharged.

[0030] The storage box 12 is provided with an active opening 123 at the driving plate 22 . The width of the active opening 123 is greater than the width of the driving plate 22 . The driving plate 22 is moved up and down through the active opening 123 to reserve active space to prevent the driving plate 22 from getting stuck when moving up and down.

[0031] In the utility model, a three-way valve pipe is arranged at the bottom of the liquid outlet pipe 13, and the water inlet of the three-way valve pipe is fixedly connected with the liquid outlet pipe 13. One of the water outlets in the three-way valve pipe is provided with a drain pipe, and the drain pipe is used for discharging the liquid when cleaning the medicine in the medicine adding box 1, so as to avoid the cleaning medicine entering the sewage and causing the imbalance of the proportion of the medicine mixture. The other water outlet is provided with a guide pipe, and the pre-mixed medicine mixture is added to the sewage through the guide pipe.

[0032] Working principle:

[0033] like Figures 1-5As shown, first, set the device at the designated position. Secondly, inject the medicine and water into the dosing tank 1 in proportion through the liquid injection port 111. After injection, start the driving motor 18 to rotate, so that the rotating shaft 17 drives the stirring impeller 14 to rotate. Under the action of the stirring impeller 14, a vortex is generated inside the dosing tank 1, thereby further improving the mixing effect. After the medicine in the dosing tank 1 is mixed with water, start one of the electric push rods 16 to drive the liquid guide seat 23 that matches it to move downward, so that the liquid outlet assembly 2 and the bottom of the dosing tank 1 are misaligned and separated. At this time, the liquid medicine can be discharged into the lower liquid storage cavity 124 for storage. When the mixed liquid enters one of the liquid storage cavities 124, start the electric push rod 16 to drive the liquid outlet assembly 2 to move upward to block the liquid outlet 15 again. At this time, clean water can be injected into the dosing tank 1 to clean the inside of the dosing tank 1 to prevent medicine residue. The liquid used to clean the inside of the dosing tank 1 is introduced into the lower cavity through the other set of liquid outlet assemblies 2 and discharged through the liquid outlet pipe 13.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
