Description

Technical Field

[0001] The present invention relates to the field of excrement processing equipment, and in particular to intelligent excrement processing equipment for animal husbandry. Background Art

[0002] Animal manure has a strong odor, but it also has high fertility and can be used for agricultural production. In farms, there is usually a lot of water mixed with manure in the animal manure storage pool due to cleaning and flushing the site. The mixture of water and manure increases the difficulty of subsequent treatment of manure, which is not convenient for subsequent transportation and fermentation processing. Therefore, it is necessary to use manure dehydration equipment to dry the manure. The Chinese invention patent with application number CN202310252599.7 proposes an automatic dehydration treatment device for livestock manure, including a main body, and a hopper is installed at the upper end of the main body. The device has a simple structure, which can reduce the possibility of clogging of the filter mesh and improve the dehydration effect of manure. However, during the use of the device, the drying is only carried out by extrusion, resulting in low drying efficiency, and the discharged sewage contains more fecal impurities, which is not convenient for subsequent treatment of sewage.

[0038] Specifically, a negative pressure cavity is formed on the outside of the feces by the negative pressure water removal device 7, the water inside the feces is extracted outwards, and the extracted water is filtered at the same time.

[0039] In this embodiment, the auxiliary extrusion device 9 includes an active cavity 91, a card plate 92, an extrusion rod 93, an extrusion spring 94 and an extrusion clamp 95. The active cavity 91 is opened at the right end of the extrusion power rotating rod 52, the extrusion spring 94 is movably connected to the right end of the extrusion power rotating rod 52, the left end of the extrusion spring 94 is inserted into the active cavity 91, the card plate 92 is installed with the left end of the extrusion spring 94, the extrusion rod 93 is installed with the right side wall of the card plate 92, the right end of the extrusion rod 93 is installed with the right inner wall of the active cavity 91, and the extrusion clamp 95 is installed with the right end of the extrusion spring 94.

[0040] Specifically, the auxiliary squeezing device 9 is used to block the feces discharge end to prevent the feces from being discharged too quickly, which causes the pressure near the tail end to decrease and affects the dehydration and drying effect of the feces.

[0041] In this embodiment, the right end of the conveying inner cylinder 1 is contracted inwardly, and the extrusion clamping plate 95 is in a truncated cone shape as a whole.

[0042] Specifically, the discharge port at the right end of the conveying inner cylinder 1 is made smaller, and the feces are squeezed out from the right end of the conveying inner cylinder 1 and push the extrusion clamp 95 to move rightward, and the extrusion clamp 95 provides a leftward resistance to the extruded feces, thereby preventing the pressure at the discharge port at the right end of the conveying inner cylinder 1 from being too low, resulting in a reduction in the extrusion dehydration effect.

[0043] In this embodiment, the outer end of the negative pressure flow-pushing plate 76 is bent in the clockwise direction, and the inner end of the negative pressure flow-pushing plate 76 is closely attached to the outer side of the partitioning and dehydration support rod 54, and the gap between adjacent partitioning and dehydration support rods 54 is 1 mm.

[0044] Specifically, the negative pressure push flow plate 76 rotates to push the gas outside the partition and dehydration support rod 54 outward, so that a negative pressure chamber is formed near the gap between the partition and dehydration support rod 54, and the water in the feces inside the partition and dehydration support rod 54 is sucked outward by negative pressure, and the water is discharged outward along the gap between the partition and dehydration support rod 54.

[0045] In this embodiment, the tooth head on the outer wall of the left power ring 77 meshes with the meshing gear 78 , and the meshing gear 78 meshes with the tooth head on the inner wall of the left transmission ring 79 .

[0046] Specifically, the negative pressure flow-pushing plate 76 drives the left power ring 77 to rotate, and the left power ring 77 drives the left transmission ring 79 to rotate in the opposite direction through the meshing gear 78, and the left transmission ring 79 drives the filter cartridge 74 to rotate in the opposite direction, so that the filter cartridge 74 rotates in the opposite direction to the scraper plate 75 and the wiper plate 73.

[0047] In this embodiment, the scraper plate 75 is composed of an outer extrusion scraper 11 and an inner push scraper 12. The outer extrusion scraper 11 is installed on the outside of the inner push scraper 12, and the slope of the cross section of the outer extrusion scraper 11 is greater than the slope of the cross section of the inner push scraper 12.

[0048] Specifically, when the inner push scraper 12 rotates, it squeezes the impurities inside the filter cylinder 74 outward and sticks to the inner wall surface of the filter cylinder 74, pressing the impurities to remove moisture from the impurities. The impurities with a large amount of accumulation are pushed to the left under the rotation of the inner push scraper 12, and finally discharged through the slag discharge notch 80.

[0049] In this embodiment, the diameter of the right end of the extrusion power rotating rod 52 is larger than the diameter of the left end, and the diameter of the right end of the inner flow guide rod 64 is larger than the diameter of the left end.

[0050] Specifically, the right pitch of the extrusion spiral blade 53 is smaller than the left pitch, and the right pitch of the pressurizing spiral blade 65 is smaller than the left pitch, so that when the feces is squeezed to the right along the inside of the extrusion power rotating rod 52, the space gradually decreases and the pressure gradually increases.

[0051] In this embodiment, the top end of the fine slag collection box 4 extends to the bottom of the filter cartridge 74 , and a separation ring is provided between the inner side of the outer tube cover 3 and the outer side of the filter cartridge 74 , and the separation ring is close to the right side of the slag discharge notch 80 .

[0052] Specifically, the impurities discharged outward through the slag discharge gap 80 are blocked by the separation ring, so that the impurities can only be discharged downward into the interior of the fine slag collection box 4 .

[0053] The working principle and use process of the present invention are as follows: the pipe of the feces pump is connected to the upper end of the injection pipe 2, and feces are pumped through the two feces pumps to draw feces along the injection pipe 2 into the interior of the conveying inner tube 1, and the extrusion motor 51 is started. The extrusion motor 51 drives the extrusion power rotating rod 52 to rotate, and the extrusion power rotating rod 52 drives the extrusion spiral blade 53 to rotate. The extrusion spiral blade 53 rotates to press the feces to the right, and the cavity space inside the conveying inner tube 1 gradually becomes smaller from left to right, and the pitch of the extrusion spiral blade 53 also gradually becomes smaller, so that the feces on the right side are squeezed together, and the moisture in the feces is discharged outward through the gap between the separating dehydration struts 54 by pressurizing. At the same time, by The hot air duct 61 transports pressurized gas, and the gas enters the inside of the connecting cover 62 along the hot air duct 61, and then enters the inside of the transverse flow chamber 63 through the connecting opening 67. After entering the inside of the transverse flow chamber 63, the gas flows to the right under the push of the pressurized spiral blade 65, and is finally discharged outward through the heating nozzle 66. The pressurized gas flows from the inside to the outside along the feces gap. The feces will be heated and dried when the gas flows. At the same time, the flowing gas will drive the water discharged under the internal pressure of the feces to flow outward, further improving the effect of drying the feces. The water flowing outward flows to the inside of the filter cartridge 74, and at the same time, the sewage discharge motor 71 is started, and the sewage discharge motor 71 drives the right rotating ring seat 72 to rotate, and the right rotating ring seat 72 drives the scraper 73 and the scraper The plate 75 and the negative pressure flow-pushing plate 76 rotate, and the negative pressure flow-pushing plate 76 rotates to push the gas outside the partition and dehydration support rod 54 outward, so that a negative pressure chamber is formed near the gap of the partition and dehydration support rod 54, and the water in the feces inside the partition and dehydration support rod 54 is sucked out by negative pressure, and the water is discharged outward along the gap of the partition and dehydration support rod 54, thereby improving the efficiency of water discharge. At the same time, the negative pressure flow-pushing plate 76 drives the filter cylinder 74 to rotate in the opposite direction through the cooperation of the left power ring 77, the meshing gear 78 and the left transmission ring 79. The rotation of the filter cylinder 74 drives the impurities attached to its inner wall to rotate, and the impurities are dehydrated and dried by centrifugal force. At the same time, the scraper plate 75 rotates from the inside of the filter cylinder 74, and the inner push scraper 12 squeezes the inside of the filter cylinder 74 when it rotates. The impurities on the side are pushed outward to the inner wall surface of the filter cylinder 74, pressing the impurities to remove the moisture in the impurities. The impurities with more accumulation are pushed to the left under the rotation of the inner push scraper 12, so that the impurities are finally discharged into the fine slag collection box 4 through the slag discharge gap 80 for storage. The water filtered by the filter cylinder 74 flows to the inner surface of the outer pipe cover 3, and the wiper 73 rotates the water inside the outer pipe cover 3 to push the filtered sewage downward through the drainage pipe 43. The dried feces are discharged through the right end of the conveying inner cylinder 1. When the feces are discharged, it is necessary to push the extrusion clamping plate 95 to drive the extrusion spring 94 to move to the right. The extrusion spring 94 drives the card plate 92 to move and compress the extrusion pull rod 93, thereby increasing the resistance of the feces to be discharged through the right end of the conveying inner cylinder 1.Finally, the feces is blocked by the squeezing splint 95 and diffused outward along the surface of the squeezing splint 95.
