Description

Technical Field

[0001] This utility model relates to an automated dosing device, belonging to the technical field of dosing equipment. Background Technology

[0002] Wastewater contains various pollutants, such as organic matter, suspended solids, grease, heavy metal ions, nitrogen, and phosphorus. These substances are difficult to remove completely without chemical treatment and can even cause serious pollution to the natural environment. By adding chemicals, harmful substances can be converted into harmless substances through a chemical reaction, thus achieving a better purification effect. This process involves the use of chemical dosing equipment.

[0003] Existing dosing equipment mostly relies on manual operation to control the dosage, and cannot automatically add chemicals based on the wastewater flow rate. This easily leads to situations where too much or too little chemicals are added to the wastewater. Too much will result in waste of chemicals, while too little will affect the effectiveness of subsequent wastewater treatment. Utility Model Content

[0004] Based on the above background, the purpose of this utility model is to provide an automated dosing device to solve the problems described in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] An automated dosing device includes a sewage transfer channel, wherein a sewage inlet is provided on the left side of the sewage transfer channel, a sewage outlet is provided at the bottom of the sewage transfer channel, and an automatic dosing mechanism is provided on the sewage transfer channel.

[0007] The automatic dosing mechanism includes a support frame, which is fixedly installed on the top of the sewage transfer channel. An extension seat is fixedly installed on the left side of the support frame, and an open channel flow meter is fixedly installed at the bottom of the extension seat. A dosing pump is fixedly installed on the top of the support frame. A fixed pipe is fixedly connected to the input end of the dosing pump, and a flexible hose is fixedly connected to the output end of the dosing pump. A support sleeve is fixedly installed on the top of the support frame, and a connecting strip is detachably connected to the inner wall of the support sleeve.

[0008] Preferably, a positioning bolt is threaded onto the outer wall of the support sleeve, and the threaded end of the positioning bolt is movably connected to the outer wall of the connecting strip.

[0009] Preferably, a cylinder is fixedly installed at the bottom of the connecting strip, and the end of the hose away from the dosing pump is fixedly connected to the outer wall of the cylinder.

[0010] Preferably, a mesh tube is fixedly connected to the middle of the cylinder, and a mesh cover is fixedly connected to the end of the cylinder.

[0011] Preferably, a support frame is fixedly installed on the right side of the support frame, and a medicine cylinder is fixedly installed on the inner wall of the support frame. The end of the fixed pipe away from the dosing pump extends into the inner cavity of the medicine cylinder.

[0012] Preferably, a rotating seat is rotatably connected to the bottom of the inner wall of the medicine cylinder, and a stirring rod is fixedly installed on the outer wall of the rotating seat.

[0013] Preferably, the bottom of the rotating seat is fixedly connected to an extension shaft, the bottom of which extends into the inner cavity of the sewage outflow tank, and a drive blade located in the inner cavity of the sewage outflow tank is fixedly installed on the outer wall of the extension shaft.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] By designing an open channel flow meter, the flow rate of sewage transferred in the sewage transfer channel can be monitored. When the sewage flow rate reaches a preset value, the dosing pump is automatically controlled to operate. The dosing pump draws a certain amount of agent from the agent cylinder and then delivers it to the inside of the cylinder, allowing the agent to pass through the screen and screen cover and be evenly distributed into the water body. This realizes the function of automatically adding a quantitative amount of agent according to the flow rate, avoiding the problem of agent waste due to excessive addition and the problem of insufficient addition affecting the sewage treatment effect, thus improving the practicality of this equipment.

In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0025] like Figures 1-4As shown, an automated dosing device includes a sewage transfer channel 1. A sewage inlet 11 is located on the left side of the sewage transfer channel 1, and a sewage outlet 12 is located at the bottom of the sewage transfer channel 1. An automatic dosing mechanism 2 is installed on the sewage transfer channel 1. The automatic dosing mechanism 2 includes a support frame 21, which is fixedly installed on the top of the sewage transfer channel 1. An extension base 22 is fixedly installed on the left side of the support frame 21, and a flow meter 23 is fixedly installed at the bottom of the extension base 22. A dosing pump 26 is fixedly installed on the top of the support frame 21. A fixed pipe 261 is fixedly connected to the input end of the dosing pump 26, and a flexible hose 262 is fixedly connected to the output end of the dosing pump 26. A support sleeve 24 is fixedly installed on the top of the support frame 21. A connecting strip 25 is detachably connected to the inner wall of the support sleeve 24. The open channel flow meter 23 is an existing structure, and the model can be LYMQ-F. Through the design of the open channel flow meter 23, the flow rate of sewage in the sewage transfer channel 1 can be monitored, and then the flow data is fed back to the external controller. When the sewage flow reaches the preset value, the external controller controls the dosing pump 26 to work. The dosing pump 26 extracts the agent inside the agent cylinder 28 through the fixed pipe 261 and then outputs it. The dosing pump 26 is an existing metering pump that can output a certain amount of agent, thereby realizing the function of automatically adding a quantitative agent according to the flow rate.

[0026] In this embodiment, a positioning bolt is threaded onto the outer wall of the support sleeve 24. The threaded end of the positioning bolt is movably connected to the outer wall of the connecting strip 25. A cylinder 251 is fixedly installed at the bottom of the connecting strip 25. The end of the hose 262 away from the dosing pump 26 is fixedly connected to the outer wall of the cylinder 251. A mesh cylinder 252 is fixedly connected to the middle of the cylinder 251, and a mesh cover 253 is fixedly connected to the end of the cylinder 251. By loosening the positioning bolt on the support sleeve 24, the connecting strip 25 can be positioned within the inner cavity of the support sleeve 24. The cylinder 251 is slidable to adjust its height, positioning it in the middle of the water flow and improving the uniformity of chemical dosing. Tightening the positioning plug allows for the positioning of the cylinder 251's height. The hose 262 is made of soft rubber, facilitating user adjustment of the cylinder 251's height. Through the design of the mesh cylinder 252 and mesh cover 253, the chemical output from the dosing pump 26 can enter the cylinder 251 through the hose 262 and then be evenly distributed through the mesh cylinder 252 and mesh cover 253.

[0027] In this embodiment, a support frame 27 is fixedly installed on the right side of the support frame 21. A medicine cylinder 28 is fixedly installed on the inner wall of the support frame 27. The end of the fixed pipe 261 away from the dosing pump 26 extends into the inner cavity of the medicine cylinder 28. A rotating seat 281 is rotatably connected to the bottom of the inner wall of the medicine cylinder 28. A stirring rod 282 is fixedly installed on the outer wall of the rotating seat 281. An extension shaft 283 is fixedly connected to the bottom of the rotating seat 281. The bottom of the extension shaft 283 extends into the inner cavity of the sewage outlet tank 12. A stirring rod located in the inner cavity of the sewage outlet tank 12 is fixedly installed on the outer wall of the extension shaft 283. The drive blade 284 drives the sewage inside the sewage transfer channel 1 to flow out through the inner cavity of the sewage outlet trough 12. The thrust of the water flow drives the drive blade 284 to rotate, which in turn drives the rotating seat 281 to rotate through the transmission of the extension shaft 283. The stirring rod 282 rotates synchronously, continuously mixing the medicine stored in the inner cavity of the medicine cylinder 28 to avoid the problem of precipitation during the storage process, thereby ensuring the effect of dosing. The fixed tube 261 is made of copper and can lock the shape of the fixed tube 261 to avoid interfering with the rotation of the stirring rod 282.

[0028] The working principle of this automated dosing device is as follows: When in use, the agent is added to the inner cavity of the agent cylinder 28 in advance, so that the sewage flows into the sewage transfer channel 1 from the sewage inlet 11, and then flows out from the sewage outlet 12. The power of the sewage outflow can drive the stirring rod 282 to rotate, mixing the agent inside the agent cylinder 28. At the same time, the flow meter 23 monitors the flow rate of the sewage in the sewage transfer channel 1, and then feeds the flow data back to the external controller. When the sewage flow rate reaches the preset value, the external controller controls the dosing pump 26 to work and output a certain amount of agent, thus realizing the automatic dosing function.

[0029] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
