Description

Technical Field

[0001] This utility model relates to the field of domestic sewage treatment technology, specifically to an activated carbon pulse spray mixing device for domestic sewage treatment. Background Technology

[0002] Domestic sewage is wastewater discharged from residents' daily lives. It mainly comes from residential and public buildings, such as houses, government offices, schools, hospitals, shops, public places, and industrial enterprise toilets. The pollutants contained in domestic sewage are mainly organic matter (such as protein, carbohydrates, fat, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses, etc.).

[0003] Activated carbon is a specially treated type of carbon with countless tiny pores on its surface. It is widely used in the filtration and treatment of waste gas and wastewater. In existing technologies, activated carbon particles are manually or using tools to throw into the sewage treatment tank. However, the contact between the activated carbon particles and domestic sewage is uneven, which affects the efficiency of domestic sewage treatment. Therefore, a pulse spray mixing device for activated carbon in domestic sewage treatment is proposed. The activated carbon particles falling into the material cylinder are sprayed into the tank by compressed air. Then, the stirring rod driven by the drive motor mixes the domestic sewage and activated carbon particles in the tank. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an activated carbon pulse spray mixing device for domestic sewage treatment. The activated carbon particles falling into the material cylinder are sprayed into the tank by compressed air, and then the stirring rod driven by the drive motor mixes the domestic sewage and activated carbon particles in the tank.

A mixing component is provided at the bottom of the box body. The mixing component includes a protective box fixed to the bottom of the box body by bolts. A drive motor is installed inside the protective box by a mounting bracket.

A storage tank is provided at the top of the connecting pipe.

[0007] By adopting the above technical solution, the activated carbon particles in the storage tank fall into the material cylinder through the connecting pipe. The solenoid valve is opened to supply pressure to the material cylinder through the downward inclined pipe, so that the activated carbon particles in the material cylinder can be sprayed into the box. The drive motor drives the stirring rod to mix the domestic sewage and activated carbon particles in the box.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Compressed air propels activated carbon granules from the material cylinder into the tank, where a drive motor then drives a stirring rod to mix the wastewater with the activated carbon granules. Figure 1-3 As shown, the activated carbon pulse spray mixing device for domestic sewage treatment according to this utility model includes a box 1. A mixing component 2 is provided at the bottom of the box 1. The mixing component 2 includes a protective box 201 fixed to the bottom of the box 1 by bolts. A drive motor 202 is installed inside the protective box 201 by a mounting bracket. The output shaft of the drive motor 202 located inside the box 1 is connected to a stirring rod 203 through a connecting sleeve.

[0022] The top of the box 1 is provided with a material cylinder 3. A connecting pipe 4 is fixed to the top of the material cylinder 3 by a flange. A downward-sloping pipe 9 is connected to one side of the connecting pipe 4 by a pipe joint. A solenoid valve 10 is connected to the top of the downward-sloping pipe 9 by a threaded groove. A storage tank 5 is provided at the top of the connecting pipe 4.

[0023] During use, the activated carbon granules in the storage tank 5 fall into the material cylinder 3 through the connecting pipe 4. The solenoid valve 10 is opened to supply pressure to the material cylinder 3 through the downward inclined pipe 9, so that the activated carbon granules in the material cylinder 3 can be sprayed into the box body 1. The drive motor 202 drives the stirring rod 203 to mix the domestic sewage and activated carbon granules in the box body 1.

[0024] For example, such as Figure 3 As shown, the present invention also includes a first electric valve 6 fixed to the bottom of the material cylinder 3 by a flange, and the first electric valve 6 is fixed to the top of the box body 1 by a flange.

[0026] For example, such as Figure 3 As shown, the present invention also includes a second electric valve 8 fixed to the top of the connecting pipe 4 by a flange, and the storage tank 5 fixed to the top of the second electric valve 8 by a flange.

[0027] When in use, open the second electric valve 8 so that the activated carbon particles in the storage tank 5 can fall into the material cylinder 3 through the connecting pipe 4.

[0033] During use, the inlet pipe 12 and outlet pipe 13 facilitate the flow of domestic sewage within the tank 1, while the tempered glass window 11 allows personnel to observe the situation inside the tank 1.

[0034] When using this utility model, personnel use bolts to connect the sewage pipe to the inlet pipe 12 and the outlet pipe 13, pour the activated carbon granules into the storage tank 5, and connect the device to an external power source using a power cord.

[0035] Open the second electric valve 8 to allow a certain amount of activated carbon particles in the storage tank 5 to fall into the material cylinder 3. Open the solenoid valve 10 to allow external compressed air to flow into the material cylinder 3 through the downward inclined pipe 9 to supply pressure to the material cylinder 3. Observe the pressure gauge 7 to understand the pressure inside the material cylinder 3. When the pressure inside the material cylinder 3 reaches the predetermined value, close the solenoid valve 10.

[0036] Open the first electric valve 6 to spray the activated carbon particles in the material cylinder 3 into the box 1, where they fall into the domestic sewage flowing in the box 1 through the inlet pipe 12 and the outlet pipe 13. Turn on the drive motor 202 to drive the stirring rod 203 to rotate at high speed, mixing the activated carbon particles and domestic sewage in the box 1.

[0037] Pressurized activated carbon particles are sprayed into the housing 1 from the material cylinder 3, and then the stirring rod 203 is driven by the drive motor 202 to mix them. The activated carbon particles come into full contact with the domestic sewage and quickly absorb pollutants such as organic compounds, inorganic substances, and heavy metals in the domestic sewage by utilizing their high specific surface area and numerous microporous structures, thereby achieving the purpose of treating domestic sewage.
