Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a coagulant addition device that can be used for wastewater treatment. Background Technology

[0002] The coagulant dosing device used in wastewater treatment is specifically designed to uniformly add coagulants (such as polyaluminum chloride, ferrous sulfate, etc.) into the wastewater to promote the coagulation and sedimentation of suspended particles, thereby purifying the water. Proper configuration and operation of the coagulant dosing device can significantly improve wastewater treatment efficiency, effectively removing suspended solids, color, organic matter, and certain dissolved substances from the water, ultimately improving effluent quality. Furthermore, optimizing the selection and dosing method of the coagulant can reduce treatment costs.

[0003] Existing coagulant addition devices typically rely on a single stirring blade for coagulant mixing. This method has significant limitations: due to the limited range of action of the stirring blade, coagulants far from the blade often fail to be fully mixed, resulting in poor coagulant flow in these areas and consequently low overall mixing efficiency. Specifically, a single stirring blade struggles to create a uniform flow field distribution throughout the container, easily causing uneven coagulant concentrations in certain areas, thus affecting the coagulation effect.

[0004] In addition, another common problem with prolonged equipment operation is the gradual accumulation of scale on the inner walls. Due to insufficient agitation, some coagulant tends to adhere to the inner walls. Over time, these deposits accumulate, not only reducing the effective volume of the equipment but also potentially becoming a breeding ground for microorganisms, further affecting the quality of the treated water. Long-term scale buildup can also place an additional burden on subsequent cleaning and maintenance work and may lead to equipment corrosion or damage, increasing operating costs and maintenance difficulty. Utility Model Content

[0005] The purpose of this utility model is to provide a coagulant addition device that can be used for sewage treatment, in order to solve the technical problems mentioned in the background art, which are that existing coagulant addition devices rely on a single stirring blade, resulting in uneven mixing, poor flowability, low efficiency, and easy accumulation of dirt on the inner wall, which increases the difficulty of cleaning and maintenance and operating costs, and affects the water treatment effect.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A coagulant addition device for sewage treatment includes an addition device body, a stirring assembly is provided on the surface of the addition device body, the stirring assembly includes a rotating rod, a first motor is installed on the top of the addition device body, pulleys are respectively installed on the output shaft of the first motor and the surface of the rotating rod, and the two pulleys are connected by belt drive, a plurality of first stirring blades are fixedly connected to the surface of the rotating rod, and a rotating disk is fixedly connected to the surface of the rotating rod.

[0007] Preferably, a fixed disk is fixedly connected to the inner cavity of the adding device body, and the top of the fixed disk is slidably connected to the rotating disk.

[0008] Preferably, the inner cavity of the rotating disk is connected to a liquid storage pipe, and a flexible tube is provided through the top of the adding device body.

[0009] Preferably, the surface of the liquid storage tube is connected to several nozzles, and the top end of the rotating rod is fixedly connected to an installation box.

[0010] Preferably, a second motor is installed in the inner cavity of the mounting box, and a long rod is rotatably connected to the inner cavity of the rotating rod, with the output shaft of the second motor connected to the top end of the long rod.

[0011] Preferably, the inner cavity of the rotating rod is rotatably connected to two symmetrically arranged running rods, and the bottom ends of the running rods and the long rod are respectively connected to two meshing bevel gears.

[0012] Preferably, the surfaces of the two operating rods are respectively connected to two meshing gears, and the surfaces of the operating rods are fixedly connected to two symmetrically arranged push plates.

[0013] Preferably, a push rod is connected to the side of the push plate away from the running rod, and a movable frame is slidably connected to both sides of the inner cavity of the rotating rod.

[0014] Preferably, the surface of the push rod is slidably connected to the inner side of the movable frame, and a plurality of fixed rods are fixedly connected to the surface of the movable frame.

[0015] Preferably, one end of the fixing rod extends through to the outside of the rotating rod and is fixedly connected to a cleaning plate. Both sides of the cleaning plate are fixedly connected to second stirring blades, and the surface of the cleaning plate is in contact with the inner wall of the adding device body.

[0016] The coagulant addition device for wastewater treatment according to this invention has the following advantages:

[0017] This is a coagulant addition device for wastewater treatment. By setting up a stirring component, it can achieve uniform stirring of the processed material and significantly improve the flowability during stirring. It avoids the problem that the coagulant far from the stirring blades cannot be fully mixed, and ensures that the coagulant concentration in the entire container is uniform, thereby improving the overall stirring effect and treatment efficiency.

[0018] Specifically, the mixing assembly includes a first mixing blade and a second mixing blade, which are driven to rotate by a rotating rod. During the mixing process, a second motor, through the linkage of a long rod, a bevel gear, and a running rod, causes the two running rods to rotate in opposite directions (towards or away from each other), and drives the moving frame to move synchronously through a push rod, adjusting the distance between the two sets of mixing blades to further enhance the uniformity and flow of the mixing.

[0019] In addition, the device is equipped with a cleaning function. A moving frame drives a cleaning plate to clean the inner wall of the device body. When cleaning is needed, the cleaning plate moves to contact the inner wall, and the rotation of the rotating rod achieves even wiping of the inner wall. Simultaneously, the rotating disc drives the liquid storage pipe and nozzle to rotate, spraying the cleaning liquid evenly onto the inner wall for thorough cleaning. This design not only improves mixing efficiency but also effectively reduces the accumulation of dirt on the inner wall, lowers the risk of equipment corrosion, extends equipment lifespan, and reduces maintenance costs and operational burden.

[0035] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a coagulant addition device for wastewater treatment.

[0036] like Figures 1-8 As shown, this utility model discloses a coagulant addition device for wastewater treatment, comprising an addition device body 1, a stirring assembly 2 disposed on the surface of the addition device body 1, the addition device body 1 being a coagulant addition device for wastewater treatment, thereby facilitating the addition of coagulant, the stirring assembly 2 including a rotating rod 21, the bottom end of the rotating rod 21 penetrating into the inner cavity of the addition device body 1 and rotatably connected to the bottom of the inner cavity of the addition device body 1, the contact area between the rotating rod 21 and the addition device body 1 is sealed to prevent leakage during uniform stirring of the coagulant, thus improving the sealing performance during processing, a first motor 22 is mounted on the top of the addition device body 1, the output shaft of the first motor 22 and the surface of the rotating rod 21 are respectively mounted with pulleys 23, and the two pulleys 23 are connected by belt drive, a plurality of first stirring blades 24 are fixedly connected to the surface of the rotating rod 21, a rotating disk 25 is fixedly connected to the surface of the rotating rod 21, and a fixed disk 221 is fixedly connected to the inner cavity of the addition device body 1, such as Figure 8As shown, several mounting rods are fixedly connected to the surface of the fixed disk 221, and one end of each mounting rod is fixedly connected to the inner cavity of the adding device body 1. This creates spray gaps, facilitating the entry of the cleaning liquid into the inner wall of the adding device body 1. The top of the fixed disk 221 is slidably connected to the rotating disk 25. A feed pipe is installed through the top of the adding device body 1, with its bottom end extending to the outer side of the bottom of the fixed disk 221. The feed pipe uses a flexible material such as a rubber hose. An outlet pipe is connected to the surface of the adding device body 1, and a valve is installed on its surface. The contact areas between the feed pipe and the outlet pipe and the adding device body 1 are sealed. A liquid storage pipe 26 is connected to the inner cavity of the rotating disk 25, and a flexible hose 27 is installed through the top of the adding device body 1. The bottom end of the hose 27 is connected to the surface of the liquid storage tube 26. The top of the hose 27 is equipped with a flange to facilitate connection with an external cleaning liquid pipeline, so that different types of cleaning liquids can enter the liquid storage tube 26. Several nozzles 28 are connected to the surface of the liquid storage tube 26, and the nozzles 28 are used in conjunction with the fixed plate 221 to facilitate the spraying of cleaning liquid into the inner wall of the adding device body 1. The top end of the rotating rod 21 is fixedly connected to the mounting box 29. The inner cavity of the mounting box 29 is equipped with a second motor 210. The inner cavity of the rotating rod 21 is rotatably connected to a long rod 211, and the output shaft of the second motor 210 is connected to the top end of the long rod 211. The inner cavity of the rotating rod 21 is rotatably connected to two symmetrically arranged running rods 212, and the running rods 212 are rotatably connected by bearings installed in the inner cavity of the rotating rod 21.

[0037] like Figures 2-8 As shown, the bottom ends of the running rod 212 and the long rod 211 are respectively connected to two meshing bevel gears 213. The surfaces of the two running rods 212 are respectively connected to two meshing gears 214. Two symmetrically arranged push plates 215 are fixedly connected to the surfaces of the running rods 212. A push rod 216 is connected to the side of the push plate 215 away from the running rod 212. Moving frames 217 are slidably connected to both sides of the inner cavity of the rotating rod 21. A groove is provided at the bottom of the inner cavity of the rotating rod 21 to slidably connect with the moving frame 217. The surface of the push rod 216 slides against the inner side of the moving frame 217. The movable frame 217 is fixedly connected to several fixed rods 218. One end of the fixed rod 218 extends through to the outside of the rotating rod 21 and is fixedly connected to a cleaning plate 219. The area where the push rod 216 and the rotating rod 21 penetrate through and contact each other is sealed. The cleaning plate 219 is fixedly connected to two sides with second stirring blades 220. The surface of the cleaning plate 219 is in contact with the inner wall of the adding device body 1. The surfaces of the first stirring blade 24 and the second stirring blade 220 are provided with several through holes. The design of the through holes reduces the resistance during stirring.

[0038] Specifically, firstly, the user delivers the coagulant and other auxiliary agents or liquids into the main body 1 of the addition device. Then, the first motor 22 is started, which drives the rotating rod 21 to rotate via the pulley 23. The rotating rod 21 then drives the first stirring blade 24 and the second stirring blade 220 to rotate. During the stirring process, the second motor 210 can also be started. The second motor 210 drives the long rod 211 to rotate, which drives the bevel gear 213 to mesh and rotate. The bevel gear 213 then drives the running rod 212 to rotate. The gears 214 on the running rod 212 mesh with each other, causing the two running rods 212 to rotate in opposite directions or away from each other. The running rod 212 drives the push rod 216 to swing, and the push rod 216 pushes the moving frame 217 to move synchronously, thereby adjusting the distance between the second stirring blade 220 and the first stirring blade 24, increasing the flow during stirring, and achieving uniform stirring.

[0039] Furthermore, when it is necessary to clean the inner wall of the adding device body 1, the moving frame 217 moves the cleaning plate 219 to contact the inner wall, and the rotation of the rotating rod 21 causes the moving frame 217 to move the cleaning plate 219 to wipe the inner wall evenly. When cleaning stops, the moving frame 217 can move the cleaning plate 219 to avoid prolonged contact with the inner wall and prevent adhesion. In addition, during the cleaning process, the rotating rod 21 drives the rotating disk 25 to rotate, and the rotating disk 25 drives the liquid storage pipe 26 and the nozzle 28 to rotate, spraying the cleaning liquid evenly on the inner wall, which facilitates the cleaning work. This design not only improves the stirring efficiency, but also effectively reduces the accumulation of dirt on the inner wall.

[0040] The working principle of a coagulant addition device for wastewater treatment is as follows: When the user transports the processed material and coagulant to the addition device body 1, the stirring component 2 is started. The stirring component 2 mixes the processed material evenly. When the inner wall of the addition device body 1 needs to be cleaned after a long period of stirring, the stirring component 2 cleans the addition device body 1 evenly, which facilitates use and improves the flow during stirring and the convenience of cleaning.

[0041] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
