Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and particularly relates to a sewage treatment powder adding device. Background Art

[0002] With the acceleration of the urbanization process and the improvement of the industrialization level, sewage treatment has become an important topic in the field of environmental protection. In the process of sewage treatment, in order to improve water quality, remove pollutants such as suspended solids, colloids, and heavy metal ions, various chemical agents such as flocculants, scale inhibitors, and bactericides are often added to the sewage. Traditional dosing methods often have problems such as dust pollution and material waste, which not only affect the operating environment but also increase the treatment cost. Therefore, it is particularly important to develop a sewage treatment powder adding device that can reduce dust and improve material utilization rate.

[0003] At present, the common sewage treatment dosing devices on the market mostly use solid powder agents, and the agents are scattered into the sewage manually or mechanically. However, this method has the following disadvantages: Dust pollution: During the feeding process, due to the small particles of the powder agent being easily scattered in the air, it causes dust pollution, poses a threat to the health of operators, and also increases the difficulty of environmental cleaning; Material waste: Due to uneven feeding or the dispersion of agent particles in the air, part of the agent fails to effectively enter the sewage, resulting in material waste and increasing the treatment cost; Complex operation: Traditional dosing methods often require manual operation, which not only has a large labor intensity but also is difficult to achieve precise control, affecting the treatment effect. Content of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a sewage treatment powder adding device, which has the advantages of being able to reduce dust and material waste during the feeding process.

[0005] In order to achieve the above purpose, the embodiment of the utility model specifically adopts the following technical scheme: A sewage treatment powder adding device includes a storage module arranged on one side of the sewage tank and a feeding module located in the sewage tank. The storage module includes a base, a storage bin is arranged on the base, and a feeder connected to the feeding module is arranged at the discharging end of the storage bin. The feeding module includes a floating body placed on the water surface, a feeding pipe is arranged on the floating body, and a conveying pipeline connected to the feeder is arranged at the upper part of the feeding pipe.

[0006] As a further improvement of the above technical scheme:

[0007] A material leveling hopper is arranged in the middle of the floating body, the upper part of the material leveling hopper is connected to the feeding pipe, and the lower part extends below the floating body.

[0008] The diameter of the material leveling hopper gradually decreases from top to bottom, and a material leveling plate is arranged at the top of the material leveling hopper.

[0009] An outlet pipe connected to the feeder is arranged at the lower part of the storage bin, and a limiting grid is arranged at the upper part.

[0010] An anti-caking device is arranged at the connection part between the outlet pipe and the feeder. The anti-caking device includes a conveying sleeve vertically installed on the outlet pipe. A rotating shaft is arranged in the conveying sleeve, and a spiral blade is arranged on the rotating shaft. One end of the conveying sleeve is connected to the feeder, and the other end is provided with a driving source for driving the rotating shaft to operate.

[0011] The feeder is selected as a powder conveying pump.

[0012] The beneficial effects of the embodiment of the present utility model are as follows: 1. This sewage treatment powder adding device includes a storage module arranged on one side of the sewage tank and a material spreading module located in the sewage tank. The storage module includes a base, a storage bin is arranged on the base, and a feeder connected to the material spreading module is arranged at the discharge end of the storage bin. The material spreading module includes a floating body placed on the water surface, a feeding pipe is arranged on the floating body, and a conveying pipeline connected to the feeder is arranged at the upper part of the feeding pipe.

[0020] The preferred implementation manners of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0021] As Figures 1-4 shown, the sewage treatment powder adding device of this embodiment includes a storage module installed on one side of the sewage tank and a material spreading module located in the sewage tank. The storage module includes a base 1, and traveling wheels are installed at the lower part of the base 1 for easy movement. A bin 2 for placing powder is installed on the base 1. A feeder 3 connected to the material spreading module is provided at the discharging end of the bin 2. The feeder 3 is a powder conveying pump. The material spreading module includes a floating body 4 placed on the water surface. The floating body 4 is made of foam board or PP material and floats on the water surface. A feeding pipe 5 is provided on the floating body 4. A conveying pipeline 6 connected to the feeder 3 is provided at the upper part of the feeding pipe 5. The feeder 3 uses the conveying pipeline 6 to convey the powdery material into the feeding pipe 5 and then sprinkle it into the sewage. Compared with the conventional throwing type material spreading method, it can carry out continuous material spreading, avoid the escape of powder during the material spreading process, reduce the harm to the operators, and at the same time reduce the environmental pollution.

[0022] A material leveling hopper 7 is provided in the middle of the floating body 4. An exhaust hole is opened at the top of the material leveling hopper 7 to facilitate the falling of the powder material. The upper part of the material leveling hopper 7 is connected to the feeding pipe 5, and the lower part extends below the floating body 4. During operation, the powder material will directly fall into the water body. If the lower surface of the material leveling hopper 7 is flush with the lower surface of the floating body 4, the powder material will adhere to the lower surface of the floating body 4. The feeding pipe 5 is an L-shaped elbow to avoid bending at the connection between the conveying pipeline 6 and the feeding pipe 5, resulting in the accumulation and blockage of materials.

[0023] The diameter of the material leveling hopper 7 gradually decreases from top to bottom. A material leveling plate 8 is installed at the top of the material leveling hopper 7. The surface of the material leveling plate 8 is arc-shaped and the slope gradually increases from top to bottom. A vertical rod is provided at the upper part of the material leveling plate 8, and a connecting rod is provided on the side wall of the vertical rod.

[0024] An outlet pipe 9 connected to the feeder 3 is provided at the lower part of the bin 2, and a limiting grid 10 is provided at the upper part. The function of the limiting grid 10 is to support the bagged powder during feeding and prevent the packaging bag from falling into the bin. The surface of the limiting grid 10 has a certain slope and extends from the periphery to the center position of the bin, and the vertical height gradually decreases.

[0025] An anti-caking device is provided at the connection between the discharge pipe 9 and the feeder 3. The anti-caking device includes a conveying sleeve 11 vertically installed with the discharge pipe 9. A rotating shaft 12 is arranged inside the conveying sleeve 11, and a spiral blade 13 is arranged on the rotating shaft 12. One end of the conveying sleeve 11 is connected to the feeder 3, and the other end is provided with a driving source 14 for driving the rotating shaft 12 to operate. The driving source 14 uses a rotary cylinder. The rotary cylinder drives the rotating shaft 12 to rotate, and then drives the spiral blade 12 to rotate, applying a forward thrust to the material to prevent the material from accumulating at the lower part of the discharge pipe 3 and affecting the spilling of the material.
