Description

Apparatus for removing moisture from livestock excretion and livestock excretion treatment system using the same}

The present invention relates to a livestock manure moisture removal device capable of removing moisture from livestock manure and a livestock manure treatment system using the same.

Livestock manure refers to manure that is discharged from cows, Korean cattle, pigs, and chickens, and livestock manure has various water contents such as high and low moisture content.

In existing devices, it is possible to remove moisture for livestock manure of pigs or chickens, but in the case of cows or Korean cattle, the manure lacks a technique to remove only moisture.

For example, in the existing device, there is a technology to remove water by applying centrifugal force and vibration, but it is difficult to commercialize the technology because the filter is blocked due to the fiber.

Alternatively, in the case of livestock manure with a low moisture content, water is additionally poured to make the manure moisture sufficient to remove moisture by centrifugation, etc., but the amount of manure is increased, thereby increasing environmental pollution.

On the other hand, the method of drying livestock manure using an electric heater is applied, but it takes about 10 to 15 days to remove moisture, so it is difficult to process a large amount of livestock manure, and the equipment of the electric heater is expensive and the electricity is expensive. There are many disadvantages.

In addition, in the case of cows, unlike pigs, a lot of fiber grass is eaten, so in the case of general existing dewatering equipment, the filter is easily clogged, causing frequent breakdowns and deteriorating the efficiency of the device. In addition, since various ancillary devices must be installed, the price of equipment increases.

In addition, the existing device should use a different device depending on the moisture content.

<Example 1-Livestock manure moisture removal device>

1 is a front cross-sectional view showing a livestock manure moisture removal device according to a first embodiment of the present invention.

Referring to Figure 1, the livestock manure moisture removal device according to an embodiment of the present invention, it may be largely composed of a housing 110, a porous filter 120, a screw (130a) and a driving means (140).

First, the housing 110 is formed in an empty interior, a hopper-shaped input part 111 is formed on the upper left, and a discharge part 112 is formed on the lower right. In addition, the urine recovery pipe 410 may be connected to the lower housing 110.

The porous filter 120 is provided inside the housing 110 and can be fixed by being coupled to the housing 110. And the porous filter 120 is disposed spaced apart from the inner circumferential surface of the housing 110. In addition, the porous filter 120 is formed in a hollow cylindrical shape to form a plurality of water discharge holes 121 penetrating the inner circumferential surface and the outer circumferential surface, and the moisture discharge hole formed in the porous filter 120 while the livestock manure is compressed. It may be discharged to the outside of the porous filter 120 through (121). In addition, the porous filter 120 is formed with an inlet 122 communicating with the inlet 111 of the housing 110 at the upper left and an outlet 123 communicating with the outlet 112 of the housing 110 at the lower right. Is formed.

The screw 130a is composed of a rotating shaft 131 and a blade 132, and the rotating shaft 131 is formed with a constant outer diameter, and the blade 132 is spirally formed along the longitudinal direction of the rotating shaft 131 and coupled. The outer shape of the blades 132 is formed to be smaller and smaller in the form of a plate while being longitudinal. And, for example, the rotating shaft 131 and the wings 132 are formed separately, and assembling the wings 132 on the rotating shaft 131 may be combined by welding or the like to form a screw 130a. And the rotating shaft 131 may be coupled to the bearing 133 so as to be rotatable on the left and right sides of the housing 110, respectively. In addition, in the screw 130a, a portion where the wing 132 is formed is disposed inside the porous filter 120, and both ends of the rotating shaft 131 may be exposed to the outside of the housing 110. At this time, the surface connecting the outer end of the blades 132, which is the surface forming the radial outer side of the screw 130a, is disposed parallel to the inner circumferential surface of the porous filter 120, and the porous filter 120 is a screw 130a ) Is formed in a shape corresponding to the outer shape, and may be formed in a shape in which the outer diameter becomes smaller as it goes in the longitudinal direction. In addition, the screw (130a) is formed so that the pitch (P) of the wing 132 is gradually smaller as it goes from left to right, and the screw (130a) is the inner circumferential surface and the rotation axis of the porous filter (120) as it goes from left to right ( The distance D between the outer circumferential surfaces of 131) is formed to be smaller and smaller as it goes from the inlet 122 side to the outlet 123 side. For reference, although the drawing shows that the blade 130a is formed in two layers, it may be formed of one blade or three or more blades.

Thus, the feed cross-sectional area of the screw 130a, which is the area where the livestock manure 500 may exist, is formed to gradually become narrower from left to right, which is the direction in which the livestock manure is transported, and accordingly, the livestock manure 500 is screw 130a. Dehydration can be easily achieved by gradually compressing toward the right of. That is, as the feed cross-sectional area decreases in the pitch direction and the depth direction as the feed direction of the livestock manure decreases, the effect of squeezing the livestock manure as a whole decreases, and the dehydration effect of the livestock manure can be maximized. Here, the pitch P of the wings 132 is a distance between adjacent wings, and the distance D is the inner circumferential surface and the rotating shaft 131 of the porous filter 120 in a direction perpendicular to the central axis of the rotating shaft 131 ) May be a straight line length between the outer circumferential surfaces. In addition, the transfer cross-sectional area may be an inner space formed by lines connecting the outer circumferential surfaces of the blades 132 and the rotation shaft 131 adjacent to each other and the radially outer ends of the blades.

In addition, the rotating shaft 131 of the screw 130a is formed as a hollow shaft with an empty inside, and a plurality of water discharge holes 131-2 penetrating the inner and outer circumferential surfaces are formed on the rotating shaft 131. That is, the water discharge holes 131-2 may be formed to penetrate through the inner space 131-1 of the rotating shaft 131 in the radial direction. Thus, water can be discharged to the inner space 131-1 of the rotating shaft 131 through the water discharge holes 131-2 formed in the rotating shaft 131, so dehydration of livestock manure is very easy.

In addition, a rotary joint 170 is coupled to one end of the rotating shaft 131 of the screw 130a, and the rotary joint 170 communicates with the inner space 131-1 of the rotating shaft 131, so that the inside of the rotating shaft 131 The water collected in the space 131-1 may be collected in the urine storage tank through the urine recovery pipe 180 connected to the rotary joint 170.

The driving means 140 may be a deceleration motor for driving the screw 130, and the driving means 140 may be fixed by being coupled to the housing 110 and the like, and the driving shaft to the rotating shaft 131 of the screw 130a. Can be connected. At this time, the livestock manure 500 supplied to the input unit 111 is compressed while being transferred from left to right by rotation of the screw 130a, and moisture is dehydrated in this process to collect in the urine storage tank 420. And the livestock manure 500 transferred by the rotation of the screw 130a is removed through the gap formed between the outer peripheral surface of the right end of the wing of the screw 130a and the inner peripheral surface of the right end of the porous filter 120 after moisture is removed. It can be discharged to the outside through the outlet 123 and the outlet 112.

Thus, the livestock manure moisture removal apparatus of the present invention is easy to remove moisture from the livestock manure containing fiber and can obtain a sufficient dehydration effect. In addition, the filter clogging failure is prevented by the fibers contained in the livestock manure, thereby improving the reliability of the livestock manure treatment device.

In addition, both sides of the rotating shaft 131 of the screw 130a are coupled through the bearings 133 coupled to the housing 110, and the gap adjusting device ( 150) may be combined. At this time, the rotating shaft 131 of the portion where the gap adjusting device 150 is coupled is formed with a male thread on the outer circumferential surface, and the gap adjusting device 150 may be a nut. Thus, when the nut disposed inside the housing 110 is tightened, the screw 130a is moved to the left, and the outer circumferential surface of the right end of the wing and the porous filter 120 of the screw 130a, which is a part that comes out after the livestock manure is dehydrated, of the porous filter 120. The gap formed between the inner circumferential surfaces of the right end becomes large. Conversely, when the nut disposed on the outside of the housing 110 is tightened, the screw 130a is moved to the right, and the outer circumferential surface of the right end of the wing and the porous filter 120 of the screw 130a, which is a part that comes out after dehydration of livestock manure, The gap formed between the inner circumferential surfaces of the right end becomes smaller. Accordingly, the degree to which the livestock manure is dehydrated can be controlled by the gap adjusting device 150.

In addition, a load preventing device 160 is installed to be connected between the inlet 122 and the outlet 123 of the porous filter 120 so that the load preventing device when the pressure inside the porous filter 120 rises above a predetermined pressure The livestock manure can be discharged to the outside of the porous filter 120 through 160. At this time, the load preventing device 160 may be connected by a pipe so that one side is connected to the porous filter 120 and the other side is connected to the inlet 111 of the housing 110.
