Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a dosing structure and a flocculation reaction pool. Background Art

[0002] Construction operations such as reservoir basin excavation, production and living site leveling, and construction road excavation destroy vegetation, resulting in a large number of exposed construction surfaces. Rainwater erosion during the flood season not only causes soil erosion, but also affects the water quality of downstream rivers. Therefore, this part of the river water needs to be purified. When dealing with some fine particles within it, flocculants are generally added to cause flocculation and precipitation, thereby achieving the effect of purifying water quality. However, the existing flocculant delivery method is generally to directly deliver it to the surface of the water flow. This delivery method easily leads to a higher flocculant content in the upper layer of water than in the lower layer of water. This may cause excessive flocculant delivery to the upper layer of water, resulting in secondary pollution, and the lower layer of water is not fully purified. Utility Model Content

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, with reference to Figures 1 to 6 , which is the first embodiment of the present utility model, provides a dosing structure, including a reaction component 100, including a reaction tank 101, and a sedimentation chamber 102 and a treatment chamber 103 that are interconnected and arranged in the reaction tank 101, wherein the treatment chamber 103 is arranged to facilitate the full contact and reaction between the flowing water and the flocculant. The dosing component 200 includes a dosing coil 201 mounted on the treatment chamber 103, and one end of the dosing coil 201 passes through the reaction tank 101 and is connected to the outside world, and the side of the dosing coil 201 close to the treatment chamber 103 is connected to a rotating part. The dosing coil 201 is connected to the external dispensing system, and the flocculant required each time can be introduced into the drug outlet sleeve 202 to avoid excessive dosage of liquid medicine and secondary pollution of the flowing water.

[0031] Furthermore, a medicine discharging sleeve 202 is rotatably mounted on one end of the rotating member away from the medicine discharging coil 201, and the inner cavity of the medicine discharging sleeve 202 is connected to the medicine discharging coil 201, and a medicine discharging hole 203 for discharging medicine is opened on the medicine discharging sleeve 202. Figure 2 As shown, the medicine outlet sleeve 202 is deep into the lower part of the processing chamber 103, and a plurality of medicine outlet holes 203 are provided on the outside. During purification, the medicine liquid inside will flow evenly from the medicine outlet holes 203 into the flowing water in the processing chamber 103, avoiding the problem of uneven distribution of medicine in the upper and lower layers of the flowing water during the purification process.

[0032] Furthermore, a sealing component 300 is provided in the medicine outlet 203, and the sealing component 300 includes a sealing cavity 301 opened in the medicine outlet 203, and the internal dimensions of the sealing cavity 301 decrease in sequence from the outside to the inside, and a sealing sleeve 304 is fixedly installed in the sealing cavity 301, and a sealing slide rod 303 is slidably installed inside the sealing sleeve 304, and a sealing plate 302 is provided at one end of the sealing slide rod 303 which is in contact with the inner wall of the sealing cavity 301, and a sealing spring 305 fixedly connected to the sealing sleeve 304 is provided at the other end. Under normal conditions, the sealing plate 302 seals the medicine outlet 203 by fitting with the sealing cavity 301, thereby isolating the inside and outside of the medicine outlet sleeve 202. When administering medicine, since the internal dimensions of the sealing cavity 301 decrease in sequence from the outside to the inside, the sealing plate 302 can be moved outward, so that a gap appears between the edge of the sealing plate 302 and the inner wall of the sealing cavity 301, thereby facilitating the flow of the medicine liquid inside the medicine outlet sleeve 202 into the treatment chamber 103.

[0033] Furthermore, a driving blade 206 is provided at the connection between the sedimentation chamber 102 and the treatment chamber 103, and a synchronous sprocket group 205 for transmission connection is provided between the driving blade 206 and the medicine discharging sleeve 202, and a stirring blade 204 is fixedly sleeved on the outside of the medicine discharging sleeve 202. The driving blade 206 provided at the connection between the sedimentation chamber 102 and the treatment chamber 103 will drive the stirring blade 204 to rotate when the water in the sedimentation chamber 102 flows into the treatment chamber 103. Because a synchronous sprocket group 205 is provided between the stirring blade 204 and the medicine discharging sleeve 202, the medicine discharging sleeve 202 will be driven to rotate synchronously, thereby causing the medicine liquid inside to generate centrifugal force, impacting the blocking plate 302, forcing it to open, thereby facilitating the flow of the medicine liquid into the treatment chamber 103. In addition, the stirring blade 204 provided on the outside of the medicine discharging sleeve 202 will rotate synchronously, thereby stirring the water in the treatment chamber 103, accelerating the rate at which it reacts with the medicine liquid.

[0034] During use, the medicine outlet sleeve 202 and the medicine outlet hole 203 are arranged so that the medicine liquid in the medicine outlet sleeve 202 flows evenly into the flowing water in the treatment chamber 103, thereby avoiding the problem of uneven distribution of medicines in the upper and lower layers of the flowing water during the purification process. At the same time, the arrangement of the stirring blades 204 accelerates the reaction between the flowing water and the flocculant, thereby improving the efficiency of flocculation and sedimentation.

[0035] Example 2, reference Figures 4 and 5, which is the second embodiment of the present utility model. Different from the previous embodiment, it further includes an adjustment component 400 for adjusting the internal space provided inside the medicine discharging sleeve 202. The adjustment component 400 includes an adjustment sleeve 401 fixedly installed at the bottom of the inner cavity of the medicine discharging sleeve 202, and an extension tube 402 is slidably installed at one end of the adjustment sleeve 401. An end of the extension tube 402 close to the adjustment sleeve 401 is provided with a telescopic spring 403 fixed thereto, and an adjustment area is constructed between the adjustment sleeve 401 and the extension tube 402 and the inner wall of the medicine discharging sleeve 202. Since the medicine liquid in the medicine discharging sleeve 202 is quantitative, the liquid level in the medicine discharging sleeve 202 will slowly drop during the sprinkling process, resulting in very little medicine being thrown out from the upper medicine discharging hole 203, thereby affecting the purification of the flowing water. To solve this problem, this embodiment proposes an adjustment component 400, which can adjust the internal space of the medicine discharging sleeve 202, thereby increasing the liquid level of the medicine inside it, so that the medicine can fully contact the flowing water. When the medicine is put into the medicine discharging sleeve 202, under the gravity of the medicine itself, it will press the extension tube 402 to move downward. When the medicine inside it decreases, the pressure on the extension tube 402 will decrease, and then under the action of the telescopic spring 403, the extension tube 402 will slowly rise, thereby achieving the effect of expanding the adjustment area and reducing the internal space of the medicine discharging sleeve 202, realizing the function of increasing the medicine liquid level in the medicine discharging sleeve 202.

[0036] Furthermore, the adjustment sleeve 401 is provided with a sealing ring 404 that fits tightly with the adjustment sleeve 401 and the extension tube 402, and a fastening spring 405 is sheathed around the sealing ring 404. The provision of the sealing ring 404 and the fastening spring 405 seals the gap between the extension tube 402 and the adjustment sleeve 401, preventing chemical corrosion of components such as the telescopic spring 403, thereby extending the service life of the device.

[0037] Furthermore, the bottom of the sedimentation chamber 102 is tilted, and the highest end is close to the processing chamber 103. The special arrangement of the bottom of the sedimentation chamber 102 increases the filtering effect of the device on solid particles in the flowing water.

[0038] During use, by cooperating with components such as the extension tube 402 and the telescopic spring 403, the adjustment area is expanded and the internal space of the medicine discharging sleeve 202 is reduced, thereby realizing the function of increasing the medicine liquid level in the medicine discharging sleeve 202, thereby avoiding the purification effect reduced due to insufficient medicine content, and utilizing the setting of the sealing ring 404 to improve the protection of components such as the telescopic spring 403 and extend their service life.

[0039] Example 3, reference Figure 7, which is the third embodiment of the present invention, further provides a flocculation reaction tank. It includes an impurity removal component 500, including an isolation filter 503 provided at the outlet of the treatment chamber 103, wherein the isolation filter 503 is provided to filter the flocculants generated in the treatment chamber 103. The connecting component 600 includes a drive motor 601 fixedly installed above the reaction tank 101, and a drive screw 602 is coaxially fixed to the output end of the drive motor 601. The setting of the drive screw 602 facilitates the power output of the drive motor 601.

[0040] Furthermore, a threaded sleeve on the driving screw 602 is provided with a connecting plate 604 for sealing the connection between the precipitation chamber 102 and the processing chamber 103. The driving screw 602 is fixed with two winding rods 603 near the driving motor 601. The outside of the winding rods 603 are wrapped with a traction rope 606. The inlet of the precipitation chamber 102 and the outlet of the processing chamber 103 are respectively provided with a connecting plate 605 fixedly connected to the traction rope 606. During drainage, the driving motor 601 controls the driving screw 602 to rotate. When the driving screw 602 rotates, it will drive the connecting plate 1 604 threadedly connected to it to block the connection between the sedimentation chamber 102 and the processing chamber 103 to prevent untreated water from flowing out directly. When the driving screw 602 rotates, the winding rod 603 coaxially fixed with it will drive the connecting plate 2 605 to rise by winding the traction rope 606, so that the clean water in the processing chamber 103 can flow out of the reaction tank 101, and the external water can flow into the sedimentation chamber 102. Then the driving motor 601 controls the driving screw 602 to rotate in the opposite direction, so that the connecting plate 2 605 descends and the connecting plate 1 604 rises, guiding the water into the processing chamber 103 for purification operation.

[0041] Furthermore, a defloating plate 501 is provided in the sedimentation chamber 102, and a mud extraction port 502 is provided on the inner wall of the treatment chamber 103. The defloating plate 501 is provided to isolate floating objects in the flowing water to prevent them from affecting the flocculation reaction in the treatment chamber 103. After a period of time, staff can manually remove floating objects between the defloating plate 501 and the sedimentation chamber 102. A mud extraction pump in conjunction with the mud extraction port 502 can also be used to extract flocculants from the treatment chamber 103, facilitating subsequent purification operations.

[0042] When in use, the flow of river water in the sedimentation chamber 102 and the treatment chamber 103 can be manually controlled by setting the connecting component 600, and the floating plate 501 can be used to isolate floating objects in the flowing water to prevent them from flowing into the treatment chamber 103 and affecting the flocculation reaction.
