Description

Slurry sampling device for each layer {SLURRY SAMPLING DEVICE BY LAYER}

The disclosed technology relates to an apparatus for layer-by-layer sampling of slurry accumulated in a slurry pit.

Since the manure slurry discharged from the pig house is recycled as a material such as compost, it is necessary to liquefy it with a certain quality. Current pig farms have begun to build slurry pits inside pig houses to reduce the cost of manure treatment, and the proportion of pit pig houses is continuously increasing.

These slurry pits have a structure in which a number of holes called 'slots' are drilled in the bottom of the barn, so that when pigs defecate, they pass through the slots and fall downward. Therefore, odorous substances are continuously generated in the slurry pit where the slurry is accumulated for a long time in the closed inner space. Odor substances can negatively affect not only farm workers but also nearby residents.

In order to manage such odors, the properties of the slurry act as important data. There is a slight difference in the properties of the slurry depending on the depth of the slurry pit. It is necessary to analyze the properties of the properties of the slurry for each layer.

1 is a side view of a layer-by-layer slurry sampling apparatus according to an embodiment of the disclosed technology. Referring to FIG. 1 , the layer-by-layer slurry sampling apparatus includes a housing 110 , a first handle 120 , a plurality of valves 130 , and a sealing member 140 .

The housing 110 has a cylindrical shape having a predetermined diameter. The housing 110 has a cylindrical shape with an empty inside of the body and is formed with a constant diameter. The diameter of the housing 110 has a predetermined size so that the body can be inserted into the inlet formed at the upper portion of the slurry pit. That is, although smaller than the inlet of the slurry pit, it may be formed with a diameter sufficient to allow the slurry to flow into the body.

Meanwhile, as the housing 110 vertically descends from the top of the slurry pit to the bottom, the slurry flows into the body. As described above, the housing 110 is lowered because the inside of the body is empty, and the slurry flows from the lower part to the upper part. At this time, it descends in the vertical direction so that the slurry flowing into the inside is not mixed.

The first handle 120 is provided on both sides of the housing to move the housing to a position where the inlet of the slurry pit is formed. The first handle 120 is provided as a pair on both sides so that the housing can be lifted and moved. The first handle 120 is provided with a metallic member to effectively support the weight of the housing, and may be covered with a rubber member to prevent slipping during movement. In one embodiment, the barn manager may directly hold the first handle 120 and lift and move the housing 110 , and a machine or robot capable of transporting the housing 110 may be connected to the first handle 120 to transfer the slurry It is also possible to move to the inlet position of the pit.

A plurality of valves 130 are provided on the side surface of the housing 110 at regular intervals. Preferably, the plurality of valves 130 may be provided on the side of the housing 110 at intervals of a height that can distinguish the characteristics of each layer in order to obtain the slurry for each layer as a sample. The interval of each valve 130 may be determined based on layer information obtained by collecting a slurry sample in advance, or may be determined at an arbitrary interval.

Meanwhile, the plurality of valves 130 are provided to respectively discharge the slurry introduced into the body of the housing 110 when the housing 110 descends to the inlet of the slurry pit. For example, when the housing 110 descends to the bottom of the slurry pit, the valve 130 descends in a locked state, and when the housing 110 rises from the slurry pit, each valve 130 opens to allow the slurry introduced into the body of the housing 110 to be opened. can be discharged At this time, since the slurry samples discharged to each valve 130 are not mixed with each other, they may have different properties for each layer. A sampling bottle for sampling may be connected to each valve 130 , and when the valve 130 is controlled and the discharge port is opened after the collection bottle is connected, the slurry for each layer may be collected into each collection bottle. The plurality of valves 130 are provided with a lever for discharging the slurry sample. The discharge port can be opened and closed by pulling or turning the lever. For example, a ball valve that controls opening/closing through a lever may be used. If the ball valve is used, the sample can be smoothly collected without clogging the inside of the valve due to the slurry inside the housing 110 .

The sealing member 140 prevents the slurry introduced into the body from flowing out when the housing 110 rises from the slurry pit. Since the housing 110 is a hollow cylindrical member, when it rises in the inserted state, the slurry introduced into the housing 110 comes out as it is. Accordingly, the sealing member 140 descends with the lower end of the housing 110 open when the housing 110 descends, and rises with the lower end of the housing 110 closed when ascending.

Meanwhile, the closing member 140 opens and closes the lower end of the housing 110 through the control of the second handle 150 . The second handle 150 is provided on the upper portion of the housing 110 . The second handle 150 includes a gripper that can be gripped by hand and can be turned in one direction, and a turning plate connected to the gripper. For example, when the barn manager grabs the gripper and rotates it in one direction, the rotating plate rotates along with it, and the sealing member can be controlled to seal the lower end of the housing.

For this operation, the second handle 150 and the sealing member 140 are connected by a sealing chain. And when the second handle 150 rotates in one direction, the sealing member 140 may be controlled to seal the lower end of the housing 110 while the sealing chain is wound. One side of the sealing member 140 is connected to the lower end of the housing 110 , and it is possible to operate in such a way that the sealing member 140 opens and closes with the connected one side as an axis. For example, when the second handle 150 is turned in one direction, the sealing member 140 is pulled toward the lower end of the housing with respect to one side to which the sealing member 140 is connected, thereby making it sealed. Conversely, if the second handle is turned in the opposite direction, the inside of the housing may be opened while being pushed from the lower end of the housing with respect to one side to which the sealing member 140 is connected.

Meanwhile, the sealing member 140 may use a rubber packing having a shape that matches the diameter of the lower end of the housing 110 . This rubber packing has a certain thickness so that it can maintain a sealed state while bearing the load of the slurry inside the housing.

2 is a view showing an upper portion of the housing 110 . A second handle 150 is provided on the upper portion of the housing 110 , and a pair of first handles 120 are provided on both sides of the body of the housing 110 . Each handle has a different purpose. For example, the first handle 120 is used for moving to the location where the inlet of the slurry pit is located while bearing the load of the housing, and the second handle 150 is for rotating the rotating plate 150a in the gripped state. can be used for A winding portion 150b is connected to the lower end of the rotating plate 150a. The winding portion 150b is used for winding or unwinding a chain connecting the second handle 150 and the sealing member 140 .

3 is a view showing a lower portion of the housing 110 . Referring to FIG. 3 , the sealing chain 140a connecting the second handle 150 and the sealing member 140 is located at the center of the housing 110 . The sealing chain 140a pulls the sealing member 140 connected to the lower end while being wound around the winding portion 150b while rotating according to the direction in which the rotating plate 150a provided at the upper end of the housing rotates. According to this process, the lower end of the housing may be sealed.

On the other hand, the sealing member 140 may be opened and closed by adjusting the angle in a state where only one side is connected. have. In this case, it is possible to control the sealing member 140 while maintaining the balance, so that it is more stable.

4 is a view showing a plurality of valves 130 provided in the housing. Referring to FIG. 4 , each of the plurality of valves 130 is provided with a lever 130a. When the barn manager turns the lever 130a to open the outlet, the slurry sample for each layer is discharged to the collecting bottle 130b, and when the outlet is locked by turning the lever 130a in the opposite direction, sampling is terminated and the collecting bottle 130b can be collected. . The slurry samples for each layer collected in this way are used as data for analyzing information such as odor components, chemical properties, and the degree of microbial community of different slurries for each layer. According to this process, it is possible to collect a slurry sample for each layer.
