Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automatic dosing device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment typically involves adding specific chemicals, requiring a dosing device. A search revealed Chinese Patent Publication No. CN222498733U, which discloses a wastewater treatment dosing device. This device includes a delivery pipe with an hourglass-shaped inner wall that gradually narrows towards the center. Two sets of spiral guide vanes are symmetrically fixed to the inner wall of the pipe. Six circular connection holes are evenly distributed near the center of the pipe. A drain outlet is located on the inner wall of the pipe and communicates with the connection holes. A delivery connection port is fixed to the outer wall of the pipe and communicates with the connection holes.

[0003] While the above-mentioned technical solution can create a chaotic state in the sewage inside the delivery pipe by using two sets of symmetrically arranged spiral guide vanes, allowing the agent to mix quickly with the sewage and increase sewage treatment efficiency, the flow rate and volume of the sewage will change during use. This technical solution cannot adjust the dosage of the agent according to the flow rate and volume of the sewage, which will affect the sewage treatment effect. Furthermore, the mixing method is limited to the spiral guide vanes alone, resulting in a single mixing method and limited effect. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic dosing device for sewage treatment, including a sewage inlet pipe, which is arranged horizontally, a treatment pipe is fixedly connected to one end of the sewage inlet pipe, the treatment pipe is arranged vertically, a flow meter is fixedly installed inside the sewage inlet pipe, a dosing mechanism that cooperates with the flow meter is installed through the top of the treatment pipe, and a mixing mechanism is fixedly installed at the bottom of the dosing mechanism.

[0006] Preferably, the dosing mechanism includes a dosing pipe that is fixedly connected to the top of the treatment pipe. The dosing pipe has a first vertical shaft inside, and a spiral conveying blade that cooperates with the inside of the dosing pipe is fixedly connected to the outer surface of the first vertical shaft, which can quantitatively deliver the wastewater treatment agent.

[0007] Preferably, a medicine storage tank is fixedly connected to the top end of the dosing tube, and a motor is fixedly installed on the top of the medicine storage tank. The output shaft of the motor is fixedly connected to the top end of the first vertical shaft to facilitate driving the first vertical shaft to rotate.

[0008] Preferably, a controller is fixedly installed on the top of the medicine storage tank, and the flow meter and the motor are both connected to the controller through wires, so that the rotation speed of the motor can be controlled according to the flow rate and flow of sewage.

[0009] Preferably, the mixing mechanism includes a second vertical shaft fixedly connected to the bottom end of the first vertical shaft, a conical guide shroud fixedly sleeved on the outer surface of the second vertical shaft, and a plurality of dispersion plates fixedly connected in a ring array on the upper surface of the conical guide shroud to facilitate the dispersion of the added wastewater treatment agent.

[0010] Preferably, a stirring frame is fixedly connected to the bottom end of the second vertical shaft, which can further stir and mix the sewage and sewage treatment agent.

[0011] This utility model provides an automatic dosing device for wastewater treatment. It has the following beneficial effects:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example:

[0019] like Figures 1 to 3 As shown, an automatic dosing device for sewage treatment includes a sewage inlet pipe 1, which is horizontally arranged. One end of the sewage inlet pipe 1 is fixedly connected to a treatment pipe 2, which is vertically arranged. A flow meter 3 is fixedly installed inside the sewage inlet pipe 1. A dosing mechanism that cooperates with the flow meter 3 is installed through the top of the treatment pipe 2. A mixing mechanism is fixedly installed at the bottom of the dosing mechanism.

[0020] The dosing mechanism includes a dosing pipe 4 that is fixedly connected to the top of the treatment pipe 2. A first vertical shaft 5 is located inside the dosing pipe 4, and a spiral conveying blade 6, which mates with the interior of the dosing pipe 4, is fixedly connected to the outer surface of the first vertical shaft 5. A storage tank 7 is fixedly connected to the top of the dosing pipe 4, and a motor 8 is fixedly mounted on the top of the storage tank 7. The output shaft of the motor 8 is fixedly connected to the top of the first vertical shaft 5. A controller 9 is fixedly mounted on the top of the storage tank 7, and both the flow meter 3 and the motor 8 are connected to the controller 9 via wires.

[0021] In use, wastewater enters the treatment pipe 2 from the wastewater inlet pipe 1. The motor 8 rotates, driving the first vertical shaft 5 and the spiral conveyor blade 6 to rotate, which can continuously and quantitatively deliver the wastewater treatment agent in the storage tank 7 to the treatment pipe 2 and mix it with the wastewater. The flow rate and flow of the wastewater can be detected by the flow meter 3, thereby controlling the speed of the motor 8. Thus, the speed and dosage of the wastewater treatment agent can be controlled according to the flow rate and flow of the wastewater, improving its practicality.

[0022] Furthermore, the controller 9 in this technical solution is existing conventional technology, which is known to those skilled in the art, and therefore is not described in detail.

[0023] The mixing mechanism includes a second vertical shaft 10 fixedly connected to the bottom end of the first vertical shaft 5. A conical guide shroud 11 is fixedly sleeved on the outer surface of the second vertical shaft 10. Multiple dispersion plates 12 are fixedly connected in a ring array on the upper surface of the conical guide shroud 11. A stirring rack 13 is fixedly connected to the bottom end of the second vertical shaft 10.

[0024] When the motor 8 drives the first vertical shaft 5 to rotate, it also drives the second vertical shaft 10 to rotate. The extruded sewage treatment agent is first guided through the conical guide shroud 11. The rotation of the second vertical shaft 10 can drive the dispersing plate 12 on the conical guide shroud 11 and the stirring rack 13 at the bottom to rotate, which can make the sewage treatment agent evenly dispersed in the sewage, thereby improving the mixing effect and thus improving the sewage treatment effect and efficiency.

[0025] Working principle: During use, sewage enters the treatment pipe 2 from the sewage inlet pipe 1. The motor 8 rotates, driving the first vertical shaft 5 and the spiral conveyor blade 6 to rotate, which can continuously and quantitatively deliver the sewage treatment agent in the storage tank 7 to the treatment pipe 2 and mix it with the sewage. The flow meter 3 can detect the flow rate and flow of the sewage, thereby controlling the speed of the motor 8. Thus, the speed and dosage of sewage treatment agent can be controlled according to the flow rate and flow of the sewage, improving practicality.

[0026] When the motor 8 drives the first vertical shaft 5 to rotate, it also drives the second vertical shaft 10 to rotate. The extruded sewage treatment agent is first guided through the conical guide shroud 11. The rotation of the second vertical shaft 10 can drive the dispersing plate 12 on the conical guide shroud 11 and the stirring rack 13 at the bottom to rotate, which can make the sewage treatment agent evenly dispersed in the sewage, thereby improving the mixing effect and thus improving the sewage treatment effect and efficiency.
