When the driving device is arranged in the reaction tank, the driving mechanism is driven by a hydraulic motor. The terminal bacteria of the two power input modes adopt a terminal bearing to fix the terminal and the bottom of the reaction tank body 100. Of course, the stirring device 130 may be connected to the tank 100 by using other stirring mechanisms or connection methods existing in the market, and is not limited herein.

For convenience of description, the contents of the following section will be referred to as a biological organic water-fertilizer reaction tank simply as a reaction tank. The working principle of the reaction tank is as follows:

when the device is used, solid-liquid separation is carried out on biological organic liquid manure to be treated, the separated solid manure is added into the fermentation tank for fermentation, the separated liquid is added into the biological organic liquid manure reaction tank, then the stirring device 130 is started, when the liquid in the tank body 100 is driven by the stirring device 130 to rotate, sediment (such as silt and the like) in the liquid is thrown onto the inner wall of the sludge discharge pipe 200 under the action of centrifugal force, is blocked by the sludge discharge pipe 200 to be decelerated, and then enters the sludge discharge pipe 200 through the second feed inlet 210 along the tangential direction. Then the sediment continues to rotate and decelerate in the mud pipe 200 under the inertia effect until the sediment settles at the bottom of the mud pipe 200. And the supernatant liquid obtained by settling the mixed liquid entering the mud discharging pipe 200 through the second feeding hole 210 flows out from the second feeding hole 210 at the higher part. When the sediment in the sludge discharge pipe 200 is accumulated to a certain degree, the rotary driving mechanism 400 is started, the sediment in the sludge discharge pipe 200 is lifted to the position of the second discharge port 220 by the rotation of the spiral conveying piece 300, and then the sediment is discharged out of the reaction tank through the second discharge port 220, so that the purification purpose is achieved.

The embodiment of the utility model provides a biological organic liquid manure retort compares with prior art, has added the mud pipe 200 of establishing the silt that is arranged in receiving the liquid in the retort to add on mud pipe 200 and established the silt that is arranged in mud pipe 200 and arrange to jar body 100 outer spiral conveying spare 300, thereby effectively avoided the deposit siltation in the organic waste to lead to the phenomenon of discharge gate jam to take place in ejection of compact pipeline. Wherein, the second feed inlet 210 on the sludge discharge pipe 200 is cut along the tangential direction of the sludge discharge pipe 200, and is in line with the rotation direction of the liquid in the reaction tank, so that the sediment can enter the sludge discharge pipe 200 more smoothly.

As a specific example, a buoyancy switch is further provided in the tank 100, so that when the liquid is filled into the reaction tank, the liquid level lifts the float upward, and when the float rises to a predetermined height, the feeding is stopped. The uppermost part in the reaction tank is reserved with a certain space without liquid, and the height of the space is greater than the length of the float switch ball rod.

Further, more than two sludge discharge pipes 200 may be provided in one reaction tank to ensure that as much sludge as possible can be discharged through the sludge discharge pipes 200. The spiral conveyance member 300 rotates in the same direction as the second feed opening 210 to prevent the sediment deposited in the sludge discharge pipe 200 from being extruded from the second feed opening 210 while the spiral conveyance member 300 operates. Two ends of the spiral conveying piece 300 are respectively and rotatably connected with the inner wall of the mud pipe 200 through bearings so as to ensure the stability of the relative position and the rotating relation of the spiral conveying piece 300 and the mud pipe 200.

In order to make the most of the sediment smoothly enter the sludge discharging pipe 200, referring to fig. 1 and 5, when the sludge discharging pipe 200 is disposed in the inner cavity of the tank body 100, the sludge discharging pipe 200 is disposed in an inclined manner, even if the sludge discharging pipe 200 is disposed at an angle to the horizontal plane, the inclined direction is a direction that the flowing direction of the liquid during stirring is lifted upwards, so as to guide the sediment located at the lower part of the tank body 100 to flow upwards, thereby making more sediment enter the sludge discharging pipe 200.

In order to make as much sediment as possible smoothly enter the sludge discharging pipe 200, referring to fig. 2 and 3, the second feeding hole 210 provided on the sludge discharging pipe 200 is a strip-shaped hole, which may be as long as the sludge discharging pipe 200 or shorter than the sludge discharging pipe 200. When the sludge discharge pipe 200 is disposed outside the tank body 100, the second feed inlet 210 is disposed at the middle upper portion of the sludge discharge pipe 200, extending from one third to one half of the upper end of the sludge discharge pipe 200, and the lower portion of the sludge discharge pipe 200 is closed for storing the sludge. The lower part of the sludge discharge pipe 200 is closed, so that the risk that the sediment settled in the sludge discharge pipe 200 is discharged through the second feed inlet 210 is effectively reduced, and the sediment removal efficiency is further ensured.

Specifically, referring to fig. 1 to 3, the length of the sludge discharge pipe 200 may be equivalent to the height of the tank 100, and the length of the second feed port 210 may be two thirds of the length of the sludge discharge pipe 200, so that as much sediment as possible can smoothly enter the sludge discharge pipe 200.

a. the ozone generating tube directly discharges in air by using the electrode, has low efficiency, and the outside of the glass tube needs to be plated with the copper-tin alloy, so the process is difficult and the cost is higher;

b. another kind of ozone generating tube is to vacuumize the glass tube first, then fill inert gas such as argon and mercury vapour as the conducting medium, the glass tube wraps a layer of metal mesh as an electrode outside, add the alternating voltage between two electrodes, make the air in the metal mesh district discharge, produce ozone, the ozone generating tube manufacturing process of this kind of structure is complicated, and there is mercury pollution problem;

c. the ozone generator 500 has high requirements on the cleanliness of the gas source and requires a dry gas source, so that the equipment has instability in long-term operation;

d. the generated oxidizing gas is single and only contains ozone.

While the sterilizer (i.e., the ozone generator 500, the plasma photo-oxidation-catalysis integrated machine, and the ultraviolet lamp 600) is operating, the stirring device 130 is turned on to stir the liquid. Under the stirring action of the stirring device 130, a part of OH-is returned to the water body at any time, so that the OH-is contacted with organic matters in the water body to be oxidized, the effect is better than that of singly using ozone when the OH-and the organic matters are combined, and the ozone floating in the gas is combined with ultraviolet rays to sterilize the gas above the water surface. Achieving the purposes of synergistic effect of the two and omnibearing sterilization of water and gas. Since the tube power of the ultraviolet lamp 600 is extremely low, the added cost is almost negligible.

Specifically, referring to fig. 6, when the ultraviolet lamp 600 is installed, a hole may be formed at the top of the tank 100, and then the ultraviolet lamp 600 is installed in the hole and connected to a power supply, the ultraviolet lamp 600 includes a lamp holder disposed outside the tank 100 and a lamp tube disposed in the lamp holder, the lamp holder is cylindrical or bell-mouth shaped, and has a downward opening to protect the lamp tube from being damaged by an external force. The metal end junction of fluorescent tube and fluorescent tube is installed on the cross section of the blind end of lamp stand to the sealing is sealed, connects the power, is used for preventing that the vapor that produces in the jar body 100 from leading to live wire and zero line short circuit, and ultraviolet lamp 600 shines the sterilization to the air above the liquid in the retort, prevents that the harmful microorganism that the liquid fermentation produced from spilling over to in the air of external world.

In both cases, i.e. flocculation and flotation conditions, the first outlet 120 is positioned at a vertical level slightly lower than the first inlet 110 by about 10-30 cm and 10-30 cm behind the sludge discharge pipe in the direction of liquid flow in the tank. At this time, the valves of the first discharge port 120 and the first feed port 110 are simultaneously opened, and the stirring device 130 is opened, so that the continuous production of flocculation separation and air flotation separation can be realized.

Further, a spiral ribbon connected with the stirring shaft through a steel bar or a blade is arranged on the stirring shaft of the stirring device 130, the direction of the movement of pushing the liquid material when the spiral ribbon rotates forwards is a downward movement, and the inclination direction of the blade is consistent with the inclination direction of the spiral ribbon.

In addition, if the scum or sludge in the sludge discharge pipe 200 is discharged without adopting the spiral conveying member 300, a bottom discharge mode can also be adopted, namely a discharge port is arranged at the bottom of the sludge discharge pipe 200 and a sealing cover is additionally arranged, and the scum or sludge is discharged by opening the sealing cover at the bottom of the sludge discharge pipe 200 during discharging.

Further, the first exhaust pipe 910 and the second exhaust pipe 920 are respectively an inverted U-shaped pipe to prevent rainwater from entering the gas treatment tank 900 through the respective exhaust pipes. Specifically, the gas outlet of the first gas exhaust pipe 910 extends to the bottom of the gas processing tank 900, and the gas inlet of the second gas exhaust pipe 920 is fixedly disposed at the top of the gas processing tank 900. The top of the gas treatment tank 900 is provided with an openable and closable seal cap 700 for opening the liquid containing the oxidizing bactericide.

Meanwhile, the bio-organic liquid manure treatment system further comprises a fermentation tank communicated with the second discharge hole 220 of the sludge discharge pipe 200, so that if unreacted solid manure exists in the sediment discharged through the sludge discharge pipe, the solid manure can be directly fed into the fermentation tank for fermentation. The fermentation tank may be the organic fertilizer fermentation tank described in the' 201921475059.0 patent.
