Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sludge fermentation equipment, and in particular to a sludge fermentation agent addition device. Background Technology
[0002] Sludge has a very complex composition, containing not only large amounts of usable components such as nitrogen, phosphorus, trace elements, and organic matter, but also toxic and persistent organic matter, pathogens, parasites, and heavy metals. It often emits a foul odor, and improper handling can cause significant harm to the ecological environment and human health. Currently, to reduce the damage of sludge to the ecological environment, workers add fermentation agents to the sludge, fermenting it for use as fertilizer.
[0003] Because sludge itself has a certain degree of viscosity, when adding fermentation agent solution, the fermentation agent is prone to uneven distribution, thus failing to achieve the original intention of uniform fermentation and affecting the fermentation effect of sludge. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] This utility model discloses a sludge fermentation agent addition device, comprising a frame and a stirring assembly mounted on the frame. A feeding assembly is located above the inlet end of the stirring assembly. The feeding assembly includes a sludge pump located on one side of the frame and a sludge tank located above the stirring assembly. The inlet pipe of the sludge pump is connected to a sludge source, and the outlet pipe of the sludge pump is inserted into the sludge tank. The bottom of the sludge tank is sloped and connected to a strip-shaped discharge pipe. Several horizontally arranged nozzles are installed inside the discharge pipe. The nozzles supply fermentation agent through a liquid supply assembly mounted on the outer wall of the sludge tank. A pressing assembly is located above the nozzles and connected to the sludge tank. An inclined pushing assembly is located inside the sludge tank and is positioned on the bottom slope of the sludge tank.
[0007] Furthermore, the mixing assembly includes a mixing tank and two augers rotatably connected inside the mixing tank. The ends of the two augers are connected to a gearbox. The gears inside the gearbox are connected to a reducer via a motor connected to the frame. A discharge port is provided at the bottom of the mixing tank at one end away from the sludge tank.
[0008] Furthermore, the sludge tank is mounted above the mixing tank via a connecting frame.
[0009] Furthermore, the top of the nozzle is provided with a slitting blade, with the cutting edge of the slitting blade facing upwards.
[0010] Furthermore, the liquid supply assembly includes a liquid supply tank and a liquid supply pump connected to the liquid supply tank. The liquid supply tank is connected to the outer wall of the sludge tank, and the liquid supply pump is connected to each of the nozzles through a connecting pipe.
[0011] Furthermore, the pressing assembly includes a first cylinder connected to the top of the sludge tank via a mounting plate, wherein the piston end of the first cylinder passes through the mounting plate and is placed inside the sludge tank before being connected to the pressing plate.
[0012] Furthermore, the inclined push assembly includes a second cylinder installed at an angle on the outer wall of the sludge tank. The piston end of the second cylinder passes through the side wall of the sludge tank and is connected to a V-shaped push plate. The bottom of the V-shaped push plate is slidably connected to the bottom surface of the sludge tank.
[0013] Furthermore, the sludge tank is also equipped with an inclined pressure plate, which is placed between the outlet pipe of the sludge pump and the strip discharge pipe.
[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0015] This invention delivers sludge into a sludge tank, where it is compressed into sheets by a discharge pipe upon discharge. The sludge is then cut open by a cutting blade, allowing the fermentation agent to be injected into the sludge through a nozzle. The mixture is then stirred by a stirring assembly to ensure thorough mixing of the sludge and the liquid, thereby improving the fermentation effect of the liquid. Attached Figure Description

The stirring assembly includes a stirring tank 7 and two augers 8 rotatably connected inside the stirring tank 7. The ends of the two augers 8 are connected to a gearbox 9. The gears in the gearbox 9 are connected to a reducer 10 via a motor connected to the frame 1. A discharge port is provided at the bottom of the stirring tank 7 at the end away from the sludge tank 4.
[0024] A feeding assembly is provided above one end of the inlet of the mixing assembly 2. The feeding assembly includes a sludge pump 3 disposed on one side of the frame 1 and a sludge tank 4 disposed above the mixing assembly. The sludge tank 4 is installed above the mixing tank 7 via a connecting frame 11.
[0025] The inlet pipe of the sludge pump 3 is connected to the sludge source, and the outlet pipe of the sludge pump 3 is inserted into the sludge tank 4. The bottom of the sludge tank 4 is inclined and connected to a strip-shaped discharge pipe 5. Several horizontally arranged nozzles 6 are installed in the discharge pipe 5. The nozzles 6 provide fermentation agent through a liquid supply assembly installed on the outer wall of the sludge tank 4. The liquid supply assembly includes a liquid supply tank 13 and a liquid supply pump 14 connected to the liquid supply tank 13. The liquid supply tank 13 is connected to the outer wall of the sludge tank 4. The liquid supply pump 14 is connected to each of the nozzles 6 through a connecting pipe. The top of the nozzle 6 is provided with a cutting blade 12. The cutting blade 12 faces upward. The cutting blade 12 cuts the sludge in half, making it easier for the nozzle 6 to inject the liquid into the sludge.
[0026] A pressing assembly is provided above the nozzle 6. The pressing assembly is connected to the sludge tank 4. The pressing assembly includes a first cylinder 15 connected to the top of the sludge tank 4 via a mounting plate 20. The piston end of the first cylinder 15 passes through the mounting plate 20 and is placed inside the sludge tank 4, and is connected to a pressing plate 16. The pressing plate 16 presses the sludge down on the strip discharge pipe 5, so as to facilitate the discharge of the sludge into the mixing assembly.
[0027] The sludge tank 4 is equipped with an inclined push assembly located on the bottom inclined surface of the sludge tank 4. The inclined push assembly includes a second cylinder 17 mounted inclined on the outer wall of the sludge tank 4. The piston end of the second cylinder 17 penetrates the side wall of the sludge tank 4 and is connected to a V-shaped push plate 18. The bottom of the V-shaped push plate 18 is slidably connected to the bottom surface of the sludge tank 4. The second cylinder 17 drives the V-shaped push plate 18 to push the sludge above the strip-shaped discharge pipe, facilitating discharge.
[0028] The sludge tank 4 is also equipped with an inclined pressure plate 19, which is placed between the outlet pipe of the sludge pump 3 and the strip discharge pipe 5. Through the cooperation of the inclined pressure plate 19 and the V-shaped push plate 18, the sludge enters the strip discharge pipe 5 in a sheet shape, thereby improving the uniformity of liquid injection.
