Description

Technical Field

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

[0002] In the field of sewage treatment, the dosing device is one of the important equipment for achieving water purification. Traditional sewage dosing devices usually use a fixed-position discharge port, and control the switch of the liquid medicine through a control valve to achieve continuous and uninterrupted discharge. However, this discharge method has significant defects: due to the fixed position of the discharge port, the discharged liquid medicine is often concentrated in a certain place in the sewage, making it difficult to achieve the purpose of uniform dispersion. Even if the sewage is in a flowing state, it takes a long time for the liquid medicine to be evenly dispersed through the flow of sewage, which directly affects the efficiency and effect of sewage treatment.

[0016] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Reference Figure 1-2 A sewage treatment dosing device includes a medicine box 100, and the medicine box 100 is designed with a space for storing liquid medicine inside to ensure that the liquid medicine can be properly stored and retained. An opening is provided on the top of the medicine box 100 to facilitate operators or automatic systems to inject liquid medicine into the medicine box. The top of the medicine box 100 is designed with an opening and closing cover to ensure that the liquid medicine will not evaporate or leak during storage and treatment. A plurality of discharge holes 110 are provided on the bottom or side wall of the medicine box 100. These discharge holes 110 are channels for discharging the liquid medicine, and their design position and size affect the distribution of the liquid medicine.

[0018] The turntable 120 is rotatably arranged on the fixed shaft 161 below the medicine box 100, and a medicine hole valve 130 corresponding to the position of the medicine discharge hole 110 is arranged on the turntable 120. The rotation of the turntable 120 causes the medicine hole valve 130 to rotate synchronously, thereby realizing the intermittent discharge of the medicine liquid, which is a key innovation point to solve the uneven distribution of the medicine liquid caused by continuous feeding in the background technology. The medicine hole valve 130 consists of two parts: a column connected to the turntable 120 and a sealing block corresponding to the medicine discharge hole 110. The column serves as the central support of the medicine hole valve 130, while the sealing block is responsible for the opening and closing operation of the medicine discharge hole 110. The sealing block is located at one end of the column and is customized according to the size and shape of the medicine discharge hole 110. The material selection of the sealing block takes into account chemical resistance and wear resistance to adapt to the chemical properties of the medicine liquid and the durability of long-term operation.

[0019] The medicine hole valve 130 rotates synchronously with the turntable 120 through a mechanical connection. The opening and closing of the medicine hole valve 130 controls the discharge of the medicine liquid, realizing an intermittent feeding mode of "open→close→open", which helps to quickly mix the medicine liquid with the flowing sewage and improve the mixing uniformity.

[0020] The temporary storage plate 140 is arranged in the medicine box 100, and has evenly distributed dispersion holes 142 thereon for temporarily storing and dispersing the discharged medicine liquid. The design of the dispersion holes 142 helps the medicine liquid to form a more uniform distribution when discharged, avoiding the problem of concentrated discharge.

[0021] The installation chamber 141 is disposed at the bottom middle raised portion of the temporary storage plate 140, and a driving mechanism 150 is disposed inside the installation chamber 141. The installation chamber 141 provides a stable installation space for the driving mechanism 150, ensuring that the driving mechanism 150 can reliably drive the turntable 120.

[0022] The output shaft of the driving mechanism 150 is fixedly connected to the top of the turntable 120, and is used to drive the turntable 120 to rotate. The driving mechanism 150 can be electric or pneumatic, etc., and its design ensures the continuity and stability of the rotation of the turntable 120.

[0023] The material leveling plate 170 is arranged in the medicine box 100, and the material leveling holes 171 are evenly distributed on the material leveling plate 170, so as to further promote the mixing of the medicine liquid and the sewage. The arrangement of the material leveling plate 170 enhances the effect of the medicine liquid dispersion and improves the efficiency of the medicine adding device.

[0024] The boss 160 is fixed to the inner bottom of the medicine box 100, and a fixed shaft 161 is fixed thereon. The design of the boss 160 provides a stable support for the fixed shaft 161, ensuring the stability of the rotating disk 120 when rotating.

[0025] The bottom of the fixed shaft 161 is fixed on the boss 160 to support and fix the turntable 120. The design of the fixed shaft 161 ensures the accuracy and reliability of the rotation of the turntable 120.

[0026] Working principle:

[0027] Injection and pretreatment of liquid medicine: The top of the medicine box 100 is provided with an opening to facilitate injection of liquid medicine therein. The liquid medicine first passes through the mixing plate 170, and the mixing holes 171 on the plate help the preliminary dispersion and mixing of the liquid medicine.

[0028] Temporary storage and dispersion of liquid medicine: The liquid medicine processed by the material leveling plate flows into the space between the temporary storage plate 140 and the material leveling plate. Here, the liquid medicine is further dispersed by colliding with the temporary storage plate 140, avoiding the liquid medicine from directly impacting the bottom of the medicine box 100 and reducing the potential load on the driving mechanism 150.

[0029] Intermittent discharge mechanism: The liquid medicine then passes through the dispersion holes 142 on the temporary storage plate 140 and enters the bottom of the medicine box 100, ready to be discharged through the discharge hole 110. The opening and closing of the discharge hole 110 is controlled by the medicine hole valve 130, which is composed of a columnar structure on the rotating disk 120 and a sealing block corresponding to the discharge hole 110. The rotation of the rotating disk 120 drives the medicine hole valve 130 to rotate synchronously, realizing the dynamic opening and closing of the discharge hole 110.

[0030] Centrifugal force assisted mixing: When the driving mechanism 150 drives the rotating disk 120 to rotate, the sealing block portion of the medicine hole valve 130 periodically moves to the top of the medicine discharge hole 110, opens the medicine discharge hole, and the medicine liquid is discharged immediately. Due to the centrifugal force generated by the rotation of the rotating disk 120, the medicine liquid is discharged in a bursting spray manner, which promotes the uniform mixing of the medicine liquid and the flowing sewage.

[0031] Intelligent control and regulation: The entire discharge process is intelligently monitored by the control system, which automatically adjusts the output of the drive mechanism 150 according to the sewage flow and water quality parameters, and controls the rotation speed of the turntable 120 to adapt to different treatment requirements.

[0032] Continuous and precise discharge of medicine: Due to the intermittent opening and closing of the medicine hole valve 130 and the continuous rotation of the turntable 120, the continuous and precise discharge of the medicine liquid is achieved, ensuring the effective mixing of the medicine liquid and sewage, and improving the efficiency and effect of sewage treatment.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
