Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment equipment field, concretely relates to a device for removing the floating sludge of slaughter wastewater biochemical pond. BACKGROUND

[0002] The sludge denitrification reaction is easy to occur in the anaerobic tank, the anoxic tank and the secondary sedimentation tank due to the high total nitrogen concentration of the slaughter wastewater, and then leads to the sludge floating, which affects the drainage water quality and the appearance.

[0003] The prior art generally sets multiple spray heads to scatter and dilute the foam in the sludge and the wastewater by spraying for the treatment of the floating sludge on the surface of the wastewater. However, the spraying effect on the removal of the sludge is not good. Or the artificial sludge fishing measure is adopted, but the labor intensity of the artificial maintenance is large, and there is the danger of falling into the water. SUMMARY

[0004] The utility model discloses a device for removing the floating sludge of slaughter wastewater biochemical pond, which automatically pumps away the floating sludge on the surface of the wastewater.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] A device for removing the floating sludge of slaughter wastewater biochemical pond, comprising a gland, a shell, a float, a water pump and a drain pipe; the gland is connected to the top of the shell, and the shell is funnel-shaped, and the suction port is formed between the shell and the gland; the hollow float is inverted conical, which is connected with the gland, and the suction channel is formed between the outer wall and the inner wall of the shell.

[0007] Further, the float is connected to the bottom of an adjusting bolt, and the adjusting bolt is threadedly connected with the gland.

[0008] Further, the adjusting bolt is provided with a scale for measuring the suction channel.

[0009] The device for removing the floating sludge of slaughter wastewater biochemical pond can automatically float on the surface of the slaughter wastewater, automatically suck the floating sludge on the surface of the wastewater and discharge to the designated area, and can be adjusted according to the thickness of the sludge. BRIEF DESCRIPTION OF DRAWINGS

[0010] Fig. 1 It is a structure schematic view of the device for removing the floating sludge of slaughter wastewater biochemical pond provided by the utility model embodiment.

[0011] Fig. 2 is a structural diagram of the adjusting bolt. DETAILED DESCRIPTION

[0012] The technical scheme of the utility model will be described below in detail with reference to the drawings and specific embodiments.

[0013] Embodiment one

[0014] As Figs. 1-2 shown, the utility model provides an equipment for removing the floating sludge of slaughter wastewater biochemical pool, including gland 1, shell 2, float 3, water pump 4 and drain pipe 5, gland 1 is connected in the top of shell 2, and shell 2 is funnel-shaped, and the suction port 21 is formed around between shell 2 and gland 1, the hollow float 3 is inverted conical, it is connected with gland 1, and the suction channel 22 that forms the communication suction port 21 is formed between the inner wall of shell 2 and the outer wall, the water inlet of water pump 4 is fixedly connected in the bottom of shell 2, and the water outlet of water pump 4 is connected drain pipe 5.

[0015] When using, the equipment can be freely put into the biochemical pool, due to the buoyancy of float 3, gland 1, shell 2 always float on the surface of wastewater, and gland 1 is slightly higher than the water surface. Water pump 4 can provide suction, so that the liquid on the surface of wastewater is sucked into suction port 21, and then is discharged through suction channel 22 via drain pipe 5. The sludge floating on the surface of wastewater will be sucked into suction port 21 along with the flowing wastewater under the action of suction.

[0016] Therefore, as long as the equipment operates, the sludge can automatically enter suction port 21 without stopping, achieving the effect of automatically removing the sludge without manual intervention. The size of float 3 is completely matched with water pump 4 and shell 2.

[0017] As a further preferred embodiment, the float 3 is connected to the bottom of an adjusting bolt 6, and the adjusting bolt 6 is threadedly connected to the gland 1. By rotating the adjusting bolt 6, the distance between the float 3 and the gland 1 can be adjusted, thereby adjusting the size of the suction port 21 and the width of the suction channel 22. The size of the suction port 21 and the width of the suction channel 22 can be freely adjusted according to the thickness of the sludge.

[0018] Since the suction port 21 and the suction channel 22 are blocked, it is not conducive to observation. Preferably, a scale (not shown) for measuring the suction channel 22 is provided on the adjusting bolt 6, so that the suction port 21 and the suction channel 22 can be adjusted to the most suitable size according to the actual situation during the adjustment process.

[0019] The utility model provides a kind of equipment for removing slaughter wastewater biochemical pond floating sludge, can be applied in slaughter wastewater biochemical pond (especially anaerobic pond), secondary sedimentation tank, solve the problem of sludge floating. High degree of automation, save manpower, reduce the danger of labor time. Flexibility is strong, can be moved to other pool at any time. Strong adaptability, can be freely adjusted according to the thickness of sludge, adapt different processing scale water pool. And simple structure, easy maintenance, easy production.

[0020] The above-described embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that, for ordinary skilled person in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
