Description

Technical Field

[0001] The utility model belongs to the field of sewage treatment, and in particular relates to a hopper for sludge treatment. Background Art

[0002] Sludge treatment is the process of reducing, stabilizing and harmless treatment of sludge. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. Unless land treatment or sewage ponds are used to treat sewage, general sewage treatment plants must have sludge treatment facilities.

[0003] A hopper is a funnel-shaped container installed on physical processing equipment for feeding. Most of the existing hoppers only have the function of feeding. At the same time, due to its funnel-shaped appearance and small bottom, the sludge will be squeezed when passing through the hopper and piled up after being discharged. When the sludge settles in the sedimentation tank, it is not easy for the accumulated and squeezed sludge to discharge its internal moisture, which will affect the efficiency of the sludge sedimentation treatment to a certain extent. Utility Model Content

[0004] In view of one or more of the above defects or improvement requirements of the prior art, the utility model provides a hopper for sludge treatment, which has the advantage of high efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides a hopper for sludge treatment, including a treatment tank, a pretreatment component is arranged inside the treatment tank, both ends of the pretreatment component respectively penetrate the treatment tank, the treatment tank is a hollow barrel structure and the bottom is closed, the right side of the bottom of the treatment tank is connected with a water outlet pipe, and a power mechanism is arranged at the bottom of the treatment tank, and the power mechanism is connected to the pretreatment component;

[0006] The pretreatment component includes a treatment pipe, the upper part of the treatment pipe passes through the treatment tank and is rotatably connected to the treatment tank, the cross-section of the treatment pipe is conical, the bottom of the treatment pipe is fixedly connected to a discharge pipe, the upper part of the discharge pipe passes through the bottom of the treatment tank and is rotatably connected to the bottom of the treatment tank through a sealed bearing, the top of the treatment pipe is fixedly connected to an expansion frame, a plurality of drainage holes are opened on the outer wall of the treatment pipe, and a plurality of stirring columns are fixedly connected to the inner wall of the treatment pipe.

[0007] The power mechanism includes a servo motor and a gear ring. The top of the servo motor is fixedly connected to the left outer wall of the bottom of the processing tank, the gear ring is fixedly sleeved on the outer wall of the discharge pipe, and a gear is fixedly connected to the output shaft of the servo motor, and the gear is meshed with the gear ring.

[0008] In general, compared with the prior art, the above technical solutions conceived by the utility model have the following beneficial effects:

[0009] The sludge treatment hopper of the utility model can break up and pre-dry the sludge before the sludge enters the sedimentation tank. When the sludge is subjected to sedimentation treatment in the sedimentation tank, the broken up sludge can not only be separated from water molecules more quickly, but also contains less water, and the amount of water required to be discharged is also less, thereby improving the efficiency of the sludge sedimentation treatment.

DETAILED DESCRIPTION

[0013] Depend on Figure 1-2 A hopper for sludge treatment is provided, comprising a treatment tank 1, a pretreatment component 2 is arranged inside the treatment tank 1, both ends of the pretreatment component 2 respectively penetrate the treatment tank 1, the treatment tank 1 is a hollow barrel structure with a closed bottom, a water outlet pipe 3 is connected to the right side of the bottom of the treatment tank 1, a power mechanism 4 is arranged at the bottom of the treatment tank 1, and the power mechanism 4 is connected to the pretreatment component 2;

[0014] The pretreatment component 2 includes a treatment tube 21, the upper part of the treatment tube 21 passes through the treatment tank 1 and is rotatably connected to the treatment tank 1. The treatment tube 21 has a conical cross section, and a discharge tube 22 is fixedly connected to the bottom of the treatment tube 21. The upper part of the discharge tube 22 passes through the bottom of the treatment tank 1 and is rotatably connected to the bottom of the treatment tank 1 through a sealing bearing 23. The top of the treatment tube 21 is fixedly connected to a flaring frame 24. A plurality of drainage holes 25 are opened on the outer wall of the treatment tube 21, and a plurality of stirring columns 26 are fixedly connected to the inner wall of the treatment tube 21.

[0015] The power mechanism 4 includes a servo motor 41 and a gear ring 42. The top of the servo motor 41 is fixedly connected to the left outer wall of the bottom of the processing tank 1, and the gear ring 42 is fixedly sleeved on the outer wall of the discharge pipe 22. A gear 43 is fixedly connected to the output shaft of the servo motor 41, and the gear 43 is meshed with the gear ring 42.

[0016] In the sludge treatment hopper of the utility model, the servo motor 41 is powered on and turns on and drives the gear ring 42, the gear 43, the discharge pipe 22, the treatment pipe 21 and the flaring frame 24 to rotate in sequence. After the sludge is poured from the flaring frame 24, the sludge continues to fall downward under the action of gravity. When the sludge passes through the treatment pipe 21, the rotating treatment pipe 21 continuously breaks up the sludge by using the stirring column 26. After the sludge contacts the inner wall of the treatment pipe 21, the centrifugal force generated when the treatment pipe 21 rotates will throw out the water molecules inside it, thereby pre-treating the sludge. The thrown out water molecules will pass through the drainage hole 25 and finally be discharged from the water outlet pipe 3. When the sludge is spun off, due to the conical treatment pipe 2 The inner cavity 1 forms a cavity with a continuously decreasing cross-sectional area, so that the pressure exerted by the fluid therein from the inlet end to the sludge outlet end is continuously increased, thereby slowing down the descending speed of the sludge, increasing the contact time between the sludge and the treatment pipe 21 and the effect of drying during pretreatment. With the continuous action of gravity, the sludge is discharged to the external sedimentation tank through the discharge pipe 22 after the above treatment to complete the feeding of the sedimentation tank. Since the sludge is broken up and pre-dried before entering the sedimentation tank, when the sedimentation treatment is carried out in the sedimentation tank, the broken up sludge can not only be separated from the water molecules more quickly, but also contains less water, and the amount of water required to be discharged is also less, thereby improving the efficiency of the sludge sedimentation treatment.
