Description

Technical Field

[0001] The utility model belongs to the technical field of solid-liquid separation, and in particular relates to a separation device with a cleaning mechanism for producing biological organic fertilizer. Background Art

[0002] Bio-organic fertilizer refers to a fertilizer made by combining specific functional microorganisms with organic materials that are mainly derived from plant and animal residues (such as livestock and poultry manure, crop straw, etc.), which have been harmlessly treated and decomposed. It has the dual effects of microbial fertilizer and organic fertilizer. In the production process of bio-organic fertilizer, the solid-liquid separation link of feces is crucial. At present, the separation technology in this link mostly adopts a spiral structure. The spiral solid-liquid separation device occupies an important position in the field of solid-liquid separation due to its high-efficiency separation ability, wide adaptability, high automation, excellent environmental performance, convenient maintenance, simple operation, large processing capacity, high reliability, high flexibility and economic practicality. However, after long-term use observation, it was found that feces are prone to precipitation during transportation to the separation device, resulting in sticky and poor fluidity of feces at the bottom of the storage tank or collection tank. The one-way spiral design is easy to get stuck due to sediment during transportation due to the large amount of solids, thereby reducing the transportation efficiency, and the residues are easy to accumulate inside the equipment and adhere to the inner wall. These residues not only affect the stability of equipment operation, but also cause a large amount of odorous gas to accumulate and be difficult to dissipate.

[0003] In order to deal with the above problems, the utility model proposes a spiral solid-liquid separation device with a cleaning mechanism for bio-organic fertilizer production, which aims to achieve solid-liquid separation while improving the conveying efficiency, effectively avoiding the stuck spiral, and facilitating comprehensive and effective cleaning of the solid-liquid separation equipment. Through this design, the continuous and stable operation of the equipment is ensured to meet production needs.

[0004] In summary, no effective solution has been proposed so far for the problems in the related technologies. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0018] Example

[0019] See also Figure 1-2The utility model provides the following technical solutions: A separation device for producing biological organic fertilizer with a cleaning mechanism, comprising a box body 1, wherein an extrusion part 2, a liquid storage part 3 and a discharge part 4 are arranged inside the box body 1. The liquid storage part 3 is located at the bottom center of the extrusion part 2, and the discharge part 4 is located at both ends of the extrusion part 2. A filter screen 5 is arranged between the extrusion part 2 and the liquid storage part 3 to ensure effective filtration of the liquid. The box body 1 is connected to a feed hopper 6 at the top center of the extrusion part 2 to facilitate the input of raw materials. An extrusion plate 7 is fixed between the extrusion part 2 and the discharge part 4, and a discharge port 8 is opened at the center thereof to realize the communication between the extrusion part 2 and the discharge part 4. A central shaft 9 is arranged inside the extrusion part 2, and the shaft bodies at both ends of the shaft respectively penetrate the discharge ports 8 of the two extrusion plates 7, and realize rotational connection with the two ends of the box body 1. At both ends of the shaft body of the central shaft 9 located inside the extrusion part 2, spiral blades 10 are welded, and the spiral blades 10 at both ends of the shaft body of the central shaft 9 are in opposite spiral directions to assist in material separation, extrusion and transmission. The central axis 9 is evenly provided with water outlets 11 for flushing the inner wall of the extrusion part 2 of the box body 1 with flushing water. A driving motor 12 is installed at one end to provide power for the entire device. The other end is rotatably connected to the water inlet cylinder 13, and the end of the water inlet cylinder 13 is installed with an end cap 14 in a threaded connection manner to ensure sealing and maintainability. The entire device is rigorously designed and has a stable structure, which is suitable for the separation needs of biological organic fertilizer production.

[0020] In order to ensure that the solid is extruded and the internal moisture is refluxed, in this embodiment, as a preferred technical solution of the utility model, the inner wall of the end where the extrusion part 2 and the discharge part 4 are connected is a conical structure, and the extrusion plate 7 is arranged at the end of the conical end of the extrusion part 2.

[0021] In order to facilitate the discharge of the solid part in the feces, in this embodiment, as a preferred technical solution of the utility model, the box body 1 is connected to a material guide pipe 15 at the bottom of the discharge part 4.

[0022] In order to facilitate the centralized discharge of the controlled liquid portion, in this embodiment, as a preferred technical solution of the utility model, a liquid outlet 16 is opened at the bottom center of the liquid storage part 3, and a control valve 17 is installed at the liquid outlet 16.

[0023] In order to prevent the rotation of the central shaft 9 from driving the connected water pipe to rotate and prevent water leakage at the rotating connection, in this embodiment, as a preferred technical solution of the utility model, a mechanical dynamic sealing structure is adopted at the rotating connection between the central shaft 9 and the water inlet cylinder 13.

[0024] In summary, the technical solution proposed by the utility model is adopted. In the solid-liquid separation process, the livestock manure is first put into the feed hopper 6, and then it falls into the extrusion part 2 of the box body 1. Subsequently, the drive motor 12 is started, and the driving force of the drive motor 12 is used to cause the central shaft 9 to rotate. The spiral blades 10 at both ends of the central shaft 9 gradually push the manure to the two ends of the extrusion part 2 of the box body 1. In this process, most of the liquid in the manure will flow into the liquid storage part 3 of the box body 1 through the filter screen 5. At the same time, the solid part of the manure is pushed to the discharge port 8 of the extrusion plate 7 with the push of the spiral blade 10. Since the discharge port 8 is penetrated by the central shaft 9, its edge size is small, so the discharge speed of the solid part is slowed down. Through the continuous pushing and squeezing of the spiral blade 10, the solid part is squeezed and filtered for a second time to further remove the liquid therein. This part of the liquid then flows back to the filter screen 5 along the tapered part at the end of the extrusion part 2 and is filtered out again. Finally, the fully squeezed solid part is squeezed out from the edge of the discharge port 8, falls into the discharge portion 4, and is discharged through the guide pipe 15;

[0025] When performing the cleaning operation, the end cap 14 at one end of the central shaft 9 must be removed first, and then the cleaning water pipe must be connected to ensure that the high-pressure water flow can smoothly enter the interior of the central shaft 9 to achieve flushing of the interior of the central shaft 9. At the same time, the cleaning water will be sprayed out through the water outlet 11 of the shaft body of the central shaft 9 to flush the interior of the box body 1 in all directions. In addition, in order to enhance the cleaning effect, the power supply of the drive motor 12 must be turned on so that the central shaft 9 rotates under the drive of the drive motor 12, thereby driving the spiral blade 10 to rotate synchronously and effectively scraping the inner wall of the extrusion part 2. In this way, after the feces adhered to the inner wall of the extrusion part 2 is softened by clean water, it can be thoroughly removed by the edge of the spiral blade 10. In order to prevent the squeezed liquid from being sucked back into the squeezed solids, the water outlet 11 is not set at both ends of the central shaft 9. When the interior of the discharge part 4 at both ends can be quickly rotated and transported by the spiral blade 10, the flushing water inside the extrusion part 2 is quickly pushed to the discharge part 4 to flush the interior of the discharge part 4, so that the cleaning water is discharged from the guide pipe 15 with the water flow to complete the entire cleaning process.

[0026] Finally, it should be noted that in the present utility model, unless otherwise clearly stipulated and limited, terms such as "installation", "setting", "connection", "fixation", and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
