Description

Technical Field

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

[0002] A common water treatment method is to add flocculants, coagulants and other chemicals to sewage to precipitate the organic matter in the sewage and kill pathogenic microorganisms. Compared with pure manual spreading, the dosing device can reduce the workload of the staff and is more common in treatment activities.

[0003] The common dosing device has a simple structure and can only dosing a single agent. However, when treating sewage, according to the different energy substances in the sewage, the corresponding agent needs to be added to effectively treat it. Each time different sewage is treated, the corresponding agent needs to be replaced. Some sewage also requires corresponding mixed agents for treatment. The corresponding agents need to be supplied to the equipment for mixing before being discharged. The process of disassembly and installation needs to be repeated, which is troublesome to operate and leads to low work efficiency. In addition, the water surface area of ​​the sewage treatment pool is large, and the drug outlet structure of the general dosing equipment is a single pipe, which cannot cover the entire pool surface. The drug will be supplied to a single position, and the agent will diffuse by itself. The mixing exchange with the sewage is too low, and the treatment effect is not good. In addition, the treated sewage is generally in a flowing state. After entering the wastewater, the agent will leave directly with the flowing water, and there is no time to diffuse to the surrounding sewage, which has a poor treatment effect on the water. This application number: CN202320970284.1, discloses a dosing device for water treatment, including a box body, a dosing pipe is provided at the upper end of the box body, a plurality of the dosing pipes are arranged and surround the central portion of the upper end of the box body, an electric control valve is provided on the dosing pipe, a dosing pipe matched with the dosing pipe is provided at the upper end of the dosing pipe, the dosing pipe and the dosing pipe are detachably connected, a drug outlet pipe is provided at the lower end of the box body, a control valve is provided on the drug outlet pipe, a shunt pipe is provided at the lower end of the drug outlet pipe, the shunt pipe includes a transverse pipe and a longitudinal pipe, the lower ends of the transverse pipe and the longitudinal pipe are both provided with drug outlets, a plurality of the drug outlets are arranged and are arranged at equal intervals on the transverse pipe and the longitudinal pipe, the device can be equipped with multiple dosing pipes at the same time, reducing the time required for replacing different drug pipes, improving work efficiency, and allowing the agent to be added to the wastewater from multiple positions, facilitating the diffusion of the agent, and stirring the wastewater flow, so that the agent is mixed with the wastewater faster, thereby improving the treatment efficiency.

[0004] However, the above scheme still has certain defects. The inventors have found through research that the above scheme lacks a cleaning device for the box body. After long-term use, a large amount of residual drugs may adhere to the inner wall of the box, which will cause inaccurate drug ratios when subsequently adding drugs to treat sewage, and there is a possibility of causing a high drug concentration in the sewage.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 4 The utility model provides a technical solution: a water treatment dosing device, including a medicine storage barrel 1, the medicine storage barrel 1 includes a barrel body 101, the bottom end of the barrel body 101 is connected to a medicine delivery pipe 102, a cleaning component 2 is arranged inside the barrel body 101, the cleaning component 2 includes a cleaning scraper ring 201, the cleaning scraper ring 201 is slidably connected to the inner wall of the barrel body 101, the cleaning scraper ring 201 is fixedly connected to the driving mechanism, the bottom end of the medicine delivery pipe 102 is rotatably connected to a rotating medicine outlet component 3, and the top surface of the barrel body 101 is connected to a medicine inlet pipe 4.

[0026] It should be noted that, during actual use, a control valve may be provided on the drug delivery tube 102 to adjust the drug flow rate, flow rate, and opening and closing, thereby reducing limitations in use and improving practicality.

[0027] See also Figure 1 and Figure 2 A stirring mechanism is also provided inside the barrel body 101 .

[0028] During the dosing process, the drug and water can be added into the barrel 101 and stirred to obtain a suitable concentration. When using multiple drugs, the drugs can also be fully mixed to improve the effect of sewage treatment.

[0029] Furthermore, the stirring mechanism includes a first motor 103, which is fixedly installed at the center of the top surface of the barrel body 101. One end of the output shaft of the first motor 103 extends into the interior of the barrel body 101 through a through hole and is fixedly connected to one end of a rotating shaft 104. A plurality of stirring rods 105 are arranged on the outer wall of the rotating shaft 104 in a circular shape and in a direction of their extension and are evenly distributed.

[0030] The first motor 103 is started to drive the rotating shaft 104 to rotate, and the several groups of stirring rods 105 arranged on the outer wall of the rotating shaft 104 are used to fully stir the several kinds of medicines and water inside the barrel body 101 to achieve the ideal mixing degree and concentration according to actual needs, thereby improving the effect of sewage treatment and reducing usage limitations.

[0031] Furthermore, a brush 106 is disposed on a surface of one end of each stirring rod 105 .

[0032] When the inside of the barrel 101 is filled with water for cleaning after the addition of the medicine is completed, the stirring mechanism can also be started to brush the inner wall of the barrel 101 with the brush 106 to play a role in auxiliary cleaning and further improve the cleaning efficiency.

[0033] See also Figure 3 The driving mechanism includes a limiting telescopic rod 203 and a screw 204, one end of the limiting telescopic rod 203 and the screw 204 are respectively fixedly connected to the two sides of the top surface of the cleaning scraper 201, and the other ends of the limiting telescopic rod 203 and the screw 204 are extended to the outside of the barrel body 101 through the through hole. The other end of the limiting telescopic rod 203 is fixedly installed on one side of the bottom surface of the mounting plate 202. The mounting plate 202 is located above the barrel body 101. A second motor 206 is fixedly installed on one side of the upper surface of the mounting plate 202. One end of the output shaft of the second motor 206 extends to the bottom of the mounting plate 202 through the through hole and is fixedly connected to a threaded sleeve 205. The screw 204 is threadedly sleeved with the threaded sleeve 205.

[0034] When the second motor 206 is started to drive the threaded sleeve 205 to rotate, because the limiting telescopic rod 203 is threadedly sleeved with the threaded sleeve 205 and fixedly connected to the cleaning scraper ring 201, and the cleaning scraper ring 201 is slidably connected to the inside of the barrel body 101 at the same time, the rotation of the threaded sleeve 205 will drive the cleaning scraper ring 201 to slide up and down relatively independently inside the barrel body 101, so that the residual medicine adhering to the inside of the barrel body 101 can be scraped off, thereby avoiding the situation where a lot of medicine remains on the inner wall of the barrel body 101 after long-term use, resulting in inaccurate medicine ratio during subsequent dosing for sewage treatment, reducing the possibility of high medicine concentration in sewage, and at the same time, it can also avoid the situation where the medicine remains for a long time and causes agglomeration to block the medicine delivery pipe 102 and the rotating medicine outlet component 3.

[0035] Furthermore, the inner wall of the cleaning scraper ring 201 is inclined.

[0036] The inclined inner wall can be more conducive to scraping off the residual medicine adhering to the inner wall of the barrel 101, thereby improving the cleaning efficiency.

[0037] Furthermore, mounting frames 5 are fixedly connected to surfaces at both ends of the mounting plate 202 .

[0038] The mounting frame 5 is used to mount the entire device so that the device can remain stable when the sewage is treated with chemicals.

[0039] See also Figure 4 The rotating medicine discharging component 3 includes a medicine storage box 301, a connecting annular groove 303 is arranged on the inner wall of the top circumference of the medicine storage box 301, a connecting protruding ring 302 corresponding to the connecting annular groove 303 is arranged on the outer wall of the bottom circumference of the medicine delivery tube 102, the connecting annular groove 303 and the connecting protruding ring 302 are rotatably connected, and a plurality of evenly distributed medicine discharging tubes 304 are arranged in a ring-shaped manner on the outer wall of the circumference of the medicine storage box 301.

[0040] The medicine storage box 301 can rotate independently relative to the medicine delivery tube 102 through the rotational connection of the connecting protruding ring 302 and the connecting annular groove 303. When the medicine storage box 301 is located as a whole in sewage, it can rotate due to the force of the sewage flow, so that the medicine can be evenly and fully discharged into the sewage flow through the medicine outlet pipe 304 arranged around it, thereby improving the uniformity of mixing of medicine and sewage and improving the sewage treatment efficiency.

[0041] Furthermore, each drug outlet pipe 304 is an arc-shaped structure.

[0042] When dosing treatment is performed on stagnant sewage, since the drug outlet pipe 304 is an arc-shaped structure, when the drug is discharged from the drug outlet pipe 304, a force relative to the drug storage box 301 will be generated, thereby also driving the drug storage box 301 to rotate independently relative to the drug delivery pipe 102, which can reduce limitations in use and increase applicable scenarios.

[0043] Furthermore, one end of a plurality of mounting rods 305 distributed in a ring shape is fixedly mounted on the inner wall of the medicine storage box 301 , a connecting shaft 306 is fixedly connected between the other ends of all the mounting rods 305 , and one end of the connecting shaft 306 is fixedly connected to an impeller 307 .

[0044] When the flow rate of the medicine is slow and the force generated when it flows out from the medicine outlet pipe 304 cannot drive the medicine storage box 301 to rotate, the medicine fluid flowing downward in the medicine delivery pipe 102 will drive the medicine storage box 301 to rotate through the impeller 307, thereby further improving the applicability and ensuring as much as possible that during the medicine adding process, the medicine storage box 301 can drive all the medicine outlet pipes 304 to rotate and discharge the medicine, thereby improving the contact and mixing degree between the medicine and the sewage and ensuring the treatment efficiency. At the same time, using the fluid force to drive the medicine storage box 301 to rotate also relatively reduces energy consumption and saves usage costs.

[0045] Working principle: The whole device is installed by mounting the mounting frame 5, so that the rotating medicine discharging component 3 is located under the water surface as a whole. According to the sewage treatment requirements, several required medicines and clean water are injected into the barrel body 101 through the medicine inlet pipe 4, and the first motor 103 is started to drive the rotating shaft 104 to rotate. Through several groups of stirring rods 105 arranged on the outer wall of the rotating shaft 104, the several medicines and water inside the barrel body 101 are fully stirred, and the ideal mixing degree and concentration are achieved according to actual needs, thereby improving the sewage treatment effect. After the medicine is mixed and prepared, the control valve provided on the medicine delivery pipe 102 is opened, and the medicine flows downward through the medicine delivery pipe 102 to the medicine storage box 301. When the medicine enters the medicine storage box 301, the fluid exerts a force on the medicine storage box 301 through the impeller 307. At the same time, the force exerted by the sewage flow on the medicine storage box 301 and the medicine discharged from the medicine outlet pipe 304 can drive the medicine storage box 301 to rotate independently relative to the medicine delivery pipe 102, so that the medicine is evenly and fully discharged into the sewage flow, thereby improving the mixing of the medicine and the sewage. The uniformity of water mixing improves the sewage treatment efficiency. At the same time, the use of fluid force to drive the medicine storage box 301 to rotate also relatively reduces energy consumption and saves use costs. After the addition of medicine is completed, clean water can be added to the barrel body 101 again through the medicine inlet pipe 4. At the same time, when the second motor 206 is started to drive the threaded sleeve 205 to rotate, because the limiting telescopic rod 203 is threadedly sleeved with the threaded sleeve 205 and is fixedly connected to the cleaning scraper ring 201, the cleaning scraper ring 201 is also slidably connected to the inside of the barrel body 101 at the same time, the rotation of the threaded sleeve 205 will drive the cleaning scraper ring 201 to slide up and down relatively independently inside the barrel body 101, so that the residual medicine adhering to the inside of the barrel body 101 can be scraped off, thereby avoiding the situation where a lot of medicines remain on the inner wall of the barrel body 101 for a long time, resulting in inaccurate medicine ratio during subsequent medicine addition for sewage treatment, reducing the possibility of high medicine concentration in sewage, and also avoiding the situation where the medicine remains for a long time to cause agglomeration and block the medicine delivery pipe 102 and the rotating medicine outlet component 3.

[0046] It should be noted that the specific models and specifications of the first motor 103 and the second motor 206 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0047] The power supply and principle of the first motor 103 and the second motor 206 are clear to those skilled in the art and will not be described in detail herein.

[0048] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
