Fig. 2 is a view showing the air purifying part 100, Fig. 3 is a view showing the operation of the loop adjusting part, and Fig. 4 is a view showing various types of purifying members 133. Fig.

2 to 4, the air purifier 100 located in the membrane treatment tank 240 to receive the treated water 50 and remove the malodor of the poultry house 10 is provided with a purifying space 101 A housing 110 having an inlet 140 and an outlet 150 and a water tub 120 disposed below the housing 110 to receive the treated water 50 containing microorganisms and a tub A cleaning loop 130 including a pair of mutually parallel band members 131 arranged between the strip member 131 and a plurality of purifying members 133 disposed between the treating member 50 A loop transfer section having a plurality of switching rollers 161 and at least one driving roller 162 so as to move in a zigzag manner in the cleaning space 101 immersed in the cleaning space 101, And a control unit for controlling the loop driving unit.

The housing 110 is in contact with the lower water tank 120 or the treatment water 50 so that the interior thereof is sealed. The inlet 140 of the housing 110 is connected to the manure mixing chamber 210 provided at the lower part of the floor 30 where the malodor generated by the manure 40 of the livestock 20 is most concentrated, And the outlet 150 is connected by a roof of the housing 10 and the outlet duct 151 so that the circulation of air in the housing 10 along with the inlet 140 is the most extensive. The air in the housing 10 can be cleaned inside the housing 110 of the air purifying part 100 through the manure mixing vessel 210 and the inflow duct 141 below the bottom 30 in the housing 10, And then enters the interior of the housing 10 again through the next outflow duct 151 and the roof.

An exhaust fan 143 is installed in the inlet duct 141 and the outlet duct 151 to suck the odor of the manure mixer 210 into the housing 110. The outlet duct 151 is connected to the air, Has an exhaust port (152) for exhausting the air in the housing (10) to the atmosphere when the unit (100) is temporarily unable to purify the odor.

The water tank 120 is accommodated in the lower portion of the housing 110 and the treated water 50 containing the rich microorganisms contained in the membrane treatment tank 240 is maintained at a certain water level.

The purifying space 101 is a space in which the air in the housing 10 is purified by the treated water 50 of the water tub 120 and the space enclosed by the housing 110.

The purification loop 130 includes a pair of band members 131 forming a closed loop and having the same length, a plurality of band member bars 132 arranged at regular intervals while maintaining a gap between the pair of band members 131, And a plurality of purifying members 133 which are coupled to the band member bar 132 and interposed between the pair of belt members 131. [

It is preferable that the strip member 131 has a material or structure that can be flexed flexibly, and that the strip member 131 has a shape of a chain as shown in FIG. 4 because it can satisfy strength and flexibility.

The purifying member 133 serves as a kind of filter that purifies the air while passing through the air of the odorous housing 10. The purifying member 133 includes a mesh 133a, a porous 133b, a polygonal 133c ). The purifying member 133 includes a filter material capable of providing an environment in which the microorganisms in the treated water 50 can be inhabited, and the filter material is made of wood having an environment in which microorganisms can be inhabited.

The purifying member 133 of the net shape 133a has a cylindrical shape passing through the center of the band member bar 132 and the surface is formed of a dense stainless steel net so that air can be circulated and corrosion by the treatment water 50 . In the purifying member 133 of the net shape 133a, a piece of wood is accommodated as the filter material 134a. Accordingly, the purifying member 133 of the net shape 133a maximizes the contact area between the microorganisms and the contaminated air due to the net-like structure and the wood in the fragmented state, so that the air purification efficiency is high. Further, since the wood in the fragmented state is used, the filter material 134a can be easily obtained, and the wood in the fragmented state can be used as a fertilizer immediately after fulfilling its function as a filter.

The purging member 133 of the porous member 133b is formed by passing the band member bar 132 through the filter material 134b or connecting the band member bar 132 to the side surface and the filter material 134b is formed on the wood And a large number of holes are formed, so that the surface area is wide and the absorption of the treatment water 50 is advantageous. The purging member 133 of the porous member 133b can use waste wood or tree branches generated after cutting, so that it is easy to obtain a material. After the use, the mushroom seed is cultured through the hole of the porous member 133b, There is an advantage that it can raise. At this time, the purging member 133 is advantageous in that the starch, protein, lignin and the like are finely decomposed to grow the mushroom.

The filter material 134c of the purging member 133 of the polygonal shape 133c is made by processing wood or compressing wood in a powder state and has protruding or recessed portions for enlarging the surface area. The purging member 133 of the polygonal mold 133c is joined to the belt member bar 132 by a separate connecting pin. The cleaning member 133 of the multi-sided mold 133c is advantageous for mass production.

The purification loop 130 having a plurality of purification members 133 between the strip members 131 is immersed in the treatment water 50 so that the microorganisms in the treatment water 50 can float in the filter material, Is arranged in a zigzag manner on the purifying space (101) in order to maximally make contact with the air of the housing (10) drawn into the housing (101). The purifying loop 130 is connected to the purifying space 101 by a loop transmission having a plurality of switching rollers 161 and at least one driving roller 162 disposed in the purifying space 101 and the process water space, And the rotation of the driving roller 162. The rotation of the driving roller 162 is controlled by the rotation of the driving roller 162 and the switching roller 161,

The switching roller 161 and the driving roller 162 are disposed in contact with the pair of belt members 131 so that a large number of pairs of the switching roller 161 and the driving roller 162 are rotatable on the same height. The switching roller 161 and the driving roller 162 are disposed over the purification space 101 and the treatment water 50 area. In the purifying space 101, the purifying loops 130 are arranged in a zigzag manner so as to be disposed over many areas of the purifying space 101. Accordingly, the cleaning loop 130, which is engaged with the switching roller 161 and the driving roller 162, is also arranged in a zigzag pattern, and has a plurality of longitudinally arranged shapes in the cleaning area and serves as a kind of filter. The air in the housing 10 passes through the purifying space 101 in the lateral direction and is purified by the microorganisms in the purifying member 133 of the purifying loop 130. The switching roller 161 or the driving roller 162 in the area of the process water 50 is disposed at the left and right ends of at least the area of the process water 50 so that when the cleaning loop 130 is immersed in the process water 50, It can be moved sufficiently to the purifying member 133 and the length of the purifying loop 130 to be immersed can be made long enough.

The switching roller 161 and the driving roller 162 of the present invention contact the chain member 131 to support the cleaning loop 130 and the driving roller 162 is rotated by the loop driving unit. It is preferable that the switching roller 161 and the driving roller 162 have a sprocket shape in order to support and move the chain-shaped purifying roof 130. This can be variously configured to effectively support and move the belt member 131 . For example, when the belt member 131 is a time belt type, it is preferable that the switching roller 161 and the driving roller 162 have the form of a time pulley.

2 and 3, the driving roller 162 is disposed at the left upper end of the purifying space 101, but the driving roller 162 is disposed at the upper left end of the purifying space 101, Or may be additionally provided at a position where another change-over roller 161 is arranged to effectively drive it continuously.

The loop driving part rotatively drives the driving roller 162 of the loop transfer part so that the closed loop cleaning loop 130 engages the switching roller 161 and the driving roller 162 to make a continuous rotation along the arrangement of the rollers, The rotation speed of the loop driving unit is controlled.

The air purifying unit 100 of the management system for a barn 10 according to the present invention continuously sucks air in the barn 10 through the inlet duct 141 connected to the manure mixing tank 210 by the exhaust fan 143 At this time, the purification loop 130 including the purification member 133 continuously rotates the space of the purification space 101 and the process water 50 by the loop transmission unit and the loop driving unit that drives the loop transmission unit. In this process, The microorganisms in the water (50) migrate to the purification member (133), and a large number of microorganisms are inhabited in the purification member (133). The air in the housing 10 passes through the purification space 101 and is purified by the microorganisms in the purification member 133. The purified air flows through the outlet 150 to the ceiling of the housing 10 . This process is continuously repeated so that the air in the housing 10 is constantly purified by the microorganisms.

The air purifying unit 100 of the management system for a barn 10 according to the present invention has the following effects.

The inlet 140 of the air purification unit 100 is installed in the manure mixing vessel 210 where the manure 40 of the livestock 20 is stored and the odor is most likely to be generated. Therefore, the odor can be inhaled and purified before it spreads in the housing 10.

The microorganisms used in the sewage treatment unit 200 are used for the air purification unit 100. [ That is, since the treated water 50 containing the microorganisms generated by the sewage treatment unit 200 is applied to the purification member 133, the utilization of the microorganisms is high. This means that when the manure (40) treatment and the air purification are respectively performed, there is no need to directly input the microorganisms into the respective systems, and the microorganism usage can be reduced.

The purifying member 133 used in the air purifying unit 100 can be used as post-use filtering. Since the used purification member 133 is a state in which many components such as protein, starch and lignin constituting the wood by microorganisms are decomposed, there is no problem even if they are directly applied to the soil. In other words, even when put into soil, it breaks down rapidly in the soil, and the inhabited microorganisms rapidly break down other contaminants in the soil, so that the plant can provide a good environment for nutrients intake.

The purification member 133 is continuously immersed in the treatment water 50 and moves in a zigzag manner in the purification space 101 and comes into contact with air in the housing 10. As the purifying member 133 is immersed in the treatment water 50 or the treatment water 50 which is separated downward from the purification member 133 enters the treatment water region again, ) Is further enhanced. That is, the aeration loop 130 is continuously immersed in the water tank 120 of the air purification unit, so that a kind of aeration action is generated, so that the activity of the microorganisms in the treated water 50 of the water tank 120 becomes more active.

The purging member 133 is continuously immersed in the treated water 50 and contains a large amount of moisture, so that the air in the pens 10 naturally has a high humidity. Therefore, it is not necessary to provide a separate facility for adjusting the humidity in the housing 10. This is because the humidity of the barn 10 can be adjusted by adjusting the speed of the exhaust fan 143 or adjusting the humidity of the purifying zone.

The capacity of the air purifier 100 is easily adjusted. The present invention can selectively apply a plurality of purifying members 133 between the strip members 131, and the number thereof is also adjustable. That is, the capacity of the air purifying unit 100 can be adjusted by adjusting the number of the purifying members 133 according to the breeding environment of the livestock 20 such as the timing, temperature, and humidity. This is because the purification member 133 can be simply added or added.

The loop conveying portion according to the present invention may have a loop adjusting portion that adjusts the height of at least two switching rollers 161 that allows the amount of immersion of the cleaning loop 130 immersed in the process water region to be adjustable.

At least two switching rollers 161 of the switching rollers 161 in the purging region are installed so as to be able to ascend and descend, and the lifting and lowering is controlled by the loop adjusting portion. The loop control unit includes at least one switching roller 161 disposed below the switching roller 161 disposed in a zigzag manner and a final switching roller 161 that moves upward and guides the cleaning loop 130 to the treated water area. The entire length of the purifying loop 130 located in the purifying region can be reduced and the length of the purifying loop 130 located in the processing water region can be made longer. By this process, the amount of immersion in which the purification loop 130 is immersed in the treated water region is regulated.

3 shows a state in which a switching roller 161 is further disposed in a zigzag pattern in a treated water area and a part of the switching roller 161 in the purification space 101 is partly lifted and lowered, The amount of the immersion in the treatment water 50 is increased by reducing the area occupied by the purification loop 130 in the purification space 101 by adjusting the ascent / descent amount. As described above, the length of the purifying loop 130 in the purifying space 101 and the treating water 50 can be adjusted by raising and lowering the switching roller 161 through the loop adjusting unit.

When the microorganisms are not sufficiently moved to the purifying member 133, the humidity in the housing 10 is low, or the amount of air passing through the purifying space 101 needs to be increased, The length of the purifying loop 130 in the space 101 is reduced and the length of the purifying loop 130 in the processing water 50 is made longer to effectively solve the above problems. This is the case in the other case.

 Further, the cleaning loop 130 may be downwardly pulled down by its own weight according to the continuous operation, so that the contact force between the band member 131 and the loop transmission portion may be weakened. In this case, some of the switching rollers 161 can be raised and lowered via the loop adjusting unit so that the cleaning loop 130 is brought into contact with the switching roller 161 and the driving roller 162 in a tight state.

The inlet 140 and the outlet 150 according to the present invention may be provided with sensor units 144 and 154 having at least one of a humidity sensor, a pressure sensor, an air pressure sensor, and an odor measurement sensor on at least one part, An exhaust fan 153 may be additionally installed in the outlet 150.

The sensor units 144 and 154 and the exhaust fans 143 and 153 can manage the housing more effectively.

When the measured value detected by the humidity sensor of the inlet 140 is lower than the humidity suitable for raising the livestock 20, the control unit increases the rotational driving speed of the roof driving unit and the rotational speed of the exhaust fans 143 and 153, So that the humidity in the indoor unit 10 is increased. At this time, it is preferable to increase the immersion amount of the purification loop 130 immersed in the treatment water 50 through the loop control unit. This operation is returned to the previous state when the measured value of the humidity sensor of the outlet 150 indicates a suitable humidity for the livestock 20 to be reared.

If the humidity value of the inlet 140 is high, the control unit stops the operation of the loop driving unit and increases the rotational speed of the exhaust fan 143. At this time, the air outlet 152 at the rear end of the outlet 150 is opened to allow air having a high humidity in the housing 10 to be released into the atmosphere.

 When the measured value detected by the temperature sensor of the inlet 140 is lower than a suitable temperature for raising the livestock 20, the control unit stops the operation of the roof driving unit and outputs cold air having a predetermined humidity to the ceiling of the housing 10 Do not get in.

If the measured value detected from the temperature sensor is high, the control unit increases the rotation driving speed of the exhaust fan 143 and the roof driving unit so that the moisture of the relatively low-temperature treated water 50 is transferred to the housing 10, . At this time, it is preferable that the purification loop 130 is sufficiently immersed in the treatment water 50 using the loop control unit so that as much moisture as possible is delivered into the housing 10.

The controller may increase the rotational speed of the exhaust fan 143 installed at the outlet 150 or the manager may increase the rotational speed of the exhaust fan 143 provided at the outlet 150. In this case, 130 to partially remove the purifying member 133 to allow the air purifying unit 100 to operate efficiently.

If the odor measurement sensor of the inlet 140 has a measurement value corresponding to the degree of contamination which is not appropriate for the livestock 20 to be raised by the air in the housing 10, the control unit controls the exhaust fan 143, So that the air in the housing 10 is rapidly circulated between the purification zone and the housing 10 and the air outlet 152 at the rear end of the outlet duct 151 is periodically opened to release partially contaminated air into the atmosphere.

The housing 110 according to the present invention may have an ultraviolet sterilizing part 170 that emits ultraviolet rays into the purification space 101 from the side. The ultraviolet sterilizing unit 170 sterilizes and disinfects the cleaning member 133 to prevent the inflow of ultraviolet rays directly to the treatment water 50. The ultraviolet sterilizer 170 removes the ultraviolet rays from the cleaning member 133 of the cleaning space 101, So that ultraviolet rays can be emitted.

The ultraviolet sterilizing unit 170 is used to sterilize harmful substances included in the new cleaning member 133 when the cleaning member 133 is installed or the existing cleaning member 133 is replaced, Thereby creating an advantageous environment in which the microorganisms in the purification member 133 are active.

In addition, when the continuous pollution degree is detected from the odor measurement sensor, the control unit controls the loop driving unit to lower the rotational driving speed of the purification loop 130 to sufficiently sterilize harmful substances by ultraviolet sterilization, When the ultraviolet sterilization of all the purifying members 133 is completed, the loop driving unit is controlled to have the rotational driving speed in the steady state again.
