Description
Technical Field
[0001] This utility model relates to the field of manure utilization and treatment technology, specifically a system for the resource utilization of pig manure. Background Technology
[0002] In the pig farming industry, a large amount of manure is generated during the breeding process. If not handled properly, it can easily cause soil, water and air pollution, and also waste the resources contained in the manure, which does not meet the requirements of environmental protection and resource recycling.
[0003] Current methods for treating manure often involve converting manure into biogas through sedimentation and fermentation in biogas digesters. Biogas can then be used by burning it in biogas digesters. However, biogas contains impurities and needs to be purified to ensure its effectiveness and the safety of the equipment.
[0004] However, current biogas purification devices have significant shortcomings: purification relies on filter media, which needs to be replaced regularly. Replacing the filter media requires disassembling and installing it, which is cumbersome and time-consuming. During this process, the biogas supply needs to be suspended, delaying the use of biogas. At the same time, the devices usually cannot store multiple sets of filter media, requiring frequent shutdowns for replenishment, which further affects the continuity and efficiency of manure resource utilization and makes it difficult to meet the stable and efficient manure treatment needs of pig farms.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figure 1-5As shown, this utility model provides a resource utilization system for pig manure. The biogas purification device includes a housing 1, an inlet pipe 2 and an outlet pipe 3 respectively connected to the inner walls of the upper and lower sides of the housing 1; an installation plate 4 is provided on the inner side wall of the housing 1, and a rotating rod 5 is rotatably installed on the installation plate 4. A first electric rotating platform 6 is installed at the bottom of the housing 1, and the first electric rotating platform 6 is connected to the bottom of the rotating rod 5. Several filter element placement components 7 are installed in a circular array around the outer periphery of the rotating rod 5; two guide plates 8 are also installed on the inner side wall of the housing 1, and connecting components 9 are slidably connected to the two guide plates 8. The two connecting components 9 are respectively connected to the bottom of the inlet pipe 2 and the top of the outlet pipe 3. An adjustment component 10 is rotatably installed on the side of the housing 1, and a second electric rotating platform 11 is installed on the outer side of the housing 1. The second electric rotating platform 11 is connected to the adjustment component 10 to drive the adjustment component 10 to rotate. The adjustment component 10 is also connected to the connecting components 9 to drive the connecting components 9 to move in opposite directions.
[0018] It should be noted here that the overall process of manure resource utilization is as follows: manure generated by pig farms is transported to a solid-liquid separator through pipelines. After separation by the solid-liquid separator, the liquid part enters the biogas digester for sedimentation and fermentation to produce biogas. The biogas is then transported to a biogas purification device for purification treatment. The purified biogas is then transported to biogas use equipment through pipelines for combustion and other uses, thus realizing the resource utilization of manure.
[0019] Core operation of biogas purification (normal purification stage): Filter media is placed inside the filter element placement assembly 7. The inlet pipe 2 and outlet pipe 3 of the biogas purification device are connected to the biogas pipeline. The opposite ends of the inlet pipe 2 and outlet pipe 3 are respectively connected to the corresponding filter element placement assembly 7 via two connecting components 9. At this time, the biogas produced by the biogas digester enters the corresponding filter element placement assembly 7 through the inlet pipe 2, is filtered and purified by the filter media, and then flows out through the outlet pipe 3 into the biogas usage equipment.
[0020] Filter media replacement stage (no downtime required): When the filter media in the currently used filter element placement assembly 7 reaches its service life and needs to be replaced, the second electric rotary table 11 is activated. The rotating component of the second electric rotary table 11 drives the adjusting component 10 to rotate, which in turn drives the two connecting components 9 to retract, disconnecting the air inlet pipe 2 and the air outlet pipe 3 from the corresponding filter element placement assembly 7. Then, the first electric rotary table 6 is activated. The rotating component of the first electric rotary table 6 drives the rotating rod 5 to rotate at a certain angle. Multiple filter element placement assemblies 7 mounted on the outer wall of the rotating rod 5 rotate with the rotating rod 5, rotating the next filter element placement assembly 7 containing new filter media between the air inlet pipe 2 and the air outlet pipe 3. Finally, the second electric rotary table 11 is activated again, causing it to drive the adjusting component 10 to rotate in the opposite direction. The adjusting component 10 drives the two connecting components 9 to extend, connecting the air inlet pipe 2 and the air outlet pipe 3 to the new filter element placement assembly 7, quickly completing the filter media replacement process without downtime and without interrupting biogas production.
[0021] The filter element placement assembly 7 includes a connecting plate 701, a placement tube 702, a sealing groove 703, and a filter screen 704. The inner end of the connecting plate 701 is connected to the side wall of the rotating rod 5, and the outer end of the connecting plate 701 is connected to the placement tube 702. The filter screen 704 is connected inside the placement tube 702, and the end face of the placement tube 702 is provided with a sealing groove 703.
[0022] The connecting plate 701 of the filter element placement assembly 7 is used to connect with the outer wall of the rotating rod 5 to achieve fixed installation of the filter element placement assembly 7 on the rotating rod 5; the placement tube 702 provides a space for the filter material to be placed inside the placement tube 702; the filter screen 704 is installed on the inner wall of the placement tube 702 to assist the filter material in filtration and further improve the biogas purification effect; the sealing groove 703 is opened on the upper and lower outer walls of the placement tube 702. When the connecting assembly 9 is connected to the filter element placement assembly 7, the sealing groove 703 can cooperate with the sealing structure of the connecting assembly 9 to enhance the sealing of the connection part, prevent biogas from leaking from the connection gap during the filtration process, and ensure the stability of biogas purification and transportation.
[0023] The connecting assembly 9 includes a sliding plate 901, a sliding groove 902, a connecting pipe 903, a corrugated pipe 904, and a sealing ring 905. The inner end of the sliding plate 901 is provided with a sliding groove 902, which is slidably embedded in the guide plate 8. The outer end of the sliding groove 902 is connected to the connecting pipe 903. One end of the connecting pipe 903 is connected to the corresponding air inlet pipe 2 and air outlet pipe 3 through the corrugated pipe 904. The other end of the connecting pipe 903 is provided with a sealing ring 905 for connecting with the sealing groove 903.
[0024] The sliding plate 901 of the connecting assembly 9 is slidably connected to the guide plate 8 through the sliding groove 902, so that the sliding plate 901 can slide stably along the guide plate 8; one end of the connecting pipe 903 is connected to the sliding plate 901, and the other end is connected to the filter element placement assembly 7 through the sealing ring 905. The sealing ring 905 can enhance the sealing of the connection between the connecting pipe 903 and the filter element placement assembly 7; the corrugated pipe 904 is connected to one end of the connecting pipe 903 and is connected to the bottom of the air inlet pipe 2 and the top of the air outlet pipe 3 respectively. The corrugated pipe 904 is extensible. When the sliding plate 901 slides along the guide plate 8 and drives the connecting pipe 903 to move, the corrugated pipe 904 can extend and retract accordingly, which not only ensures the continuity of biogas transportation, but also does not hinder the movement of the connecting pipe 903, and ensures the smooth realization of the contraction or extension action of the connecting assembly 9.
[0025] The adjustment assembly 10 includes a rotating shaft 1001, a disc 1002 installed at one end of the rotating shaft 1001, and two traction rods 1003 rotatably installed on the outer wall of one side of the disc 1002. The rotating shaft 1001 is connected to the second electric rotary table 11, and the other end of the traction rod 1003 is rotatably connected to the outer wall of the sliding plate 901.
[0026] It should be noted that when the second electric rotary table 11 is started, its rotating component drives the rotating shaft 1001 to rotate, and the rotating shaft 1001 drives the disc 1002 to rotate synchronously. One end of the traction rod 1003 is rotatably mounted on the outer wall of one side of the disc 1002, and the other end is connected to the connecting assembly 9. When the disc 1002 rotates, it will generate a pulling or pushing force on the connecting assembly 9 through the traction rod 1003, thereby driving the connecting assembly 9 to realize the contraction or extension action, providing power transmission for the connection or disconnection of the air inlet pipe 2, the air outlet pipe 3 and the filter element placement assembly 7. The end of the traction rod 1003 away from the disc 1002 is rotatably connected to the outer wall of the sliding plate 901. This rotatable connection structure provides the traction rod 1003 with a degree of freedom of movement to drive the sliding plate 901.
[0027] The top of the housing 1 has a fixing opening, and a door panel 12 is provided on the fixing opening. The fixing opening on the outer wall of the top of the housing 1 provides an operating channel for the maintenance of the filter element placement assembly 7 and the replenishment of filter media.
[0028] Working principle:
[0029] I. Overall System Workflow
[0030] The manure produced by pig farms is transported to a solid-liquid separator through pipelines. After solid-liquid separation, the liquid manure enters a biogas digester through pipelines, where it undergoes sedimentation and fermentation to produce biogas. The biogas is then transported to a biogas purification device through pipelines to remove impurities and other harmful substances. The purified biogas is then transported through pipelines to biogas-using equipment for combustion and other purposes, thus realizing the resource utilization of pig farm manure.
[0031] II. Core Working Principle of Biogas Purification Device
[0032] (I) Normal purification phase
[0033] Filter media placement and pipeline connection: Place filter media in the filter element placement assembly 7, connect the inlet pipe 2 and outlet pipe 3 of the biogas purification device to the biogas pipeline, and connect the bottom of the inlet pipe 2 and the top of the outlet pipe 3 to the corresponding filter element placement assembly 7 through two connecting assemblies 9 to form a complete biogas purification channel.
[0034] Biogas filtration and purification: The biogas produced by the biogas digester enters the corresponding filter element placement component 7 through the air inlet pipe 2. The biogas is filtered by the filter material in the filter element placement component 7 to remove impurities, moisture and other pollutants. The purified biogas then flows out through the air outlet pipe 3 and enters the subsequent biogas use equipment.
[0035] (ii) Filter media replacement stage (no machine shutdown required)
[0036] Disconnection: When the filter material in the currently used filter element placement assembly 7 reaches the end of its service life and needs to be replaced, the second electric rotary table 11 is started. The rotating part of the second electric rotary table 11 drives the adjustment assembly 10 to rotate. The adjustment assembly 10 drives the two connecting assemblies 9 to retract, so that the air inlet pipe 2 and the air outlet pipe 3 are disconnected from the corresponding filter element placement assembly 7.
[0037] Switching filter element placement assembly: Start the first electric rotary table 6. The rotating part of the first electric rotary table 6 drives the rotating rod 5 to rotate at a certain angle. Since multiple filter element placement assemblies 7 are equidistantly installed on the outer wall of the rotating rod 5, when the rotating rod 5 rotates, it will rotate the next filter element placement assembly 7 containing new filter material to between the air inlet pipe 2 and the air outlet pipe 3.
[0038] Reconnection: Restart the second electric rotary table 11 to drive the adjustment component 10 to rotate in the opposite direction. The adjustment component 10 drives the two connecting components 9 to stretch, so that the air inlet pipe 2 and the air outlet pipe 3 are connected to the new filter element placement component 7, thus restoring the biogas purification process. The whole process does not require stopping the machine and does not affect the use of biogas.
[0039] (III) Working Principle of Key Components
[0040] Filter element placement assembly 7: Connecting plate 701 is used to fix filter element placement assembly 7 to the outer wall of rotating rod 5; placement tube 702 provides placement space for filter media; filter screen 704 assists filter media filtration and improves purification effect; sealing groove 703 cooperates with the sealing structure of connecting assembly 9 to prevent biogas leakage.
[0041] Connecting component 9: The sliding plate 901 slides along the guide plate 8 through the sliding groove 902 to ensure the stable movement of the connecting component 9; the connecting pipe 903 realizes biogas transportation; the sealing ring 905 enhances the sealing performance of the connection with the filter element placement component 7; the corrugated pipe 904 is telescopic to adapt to the movement of the connecting pipe 903 and ensure continuous biogas transportation.
[0042] Adjustment component 10: The second electric rotary table 11 drives the rotating shaft 1001 to rotate, and the rotating shaft 1001 drives the disc 1002 to rotate synchronously. The disc 1002 pulls or pushes the sliding plate 901 through the traction rod 1003 to realize the contraction and extension of the connecting component 9.
[0043] Door panel 12: During normal operation, door panel 12 is closed to prevent external impurities from entering the interior of housing 1; when maintenance or replenishment of filter media is required, door panel 12 is opened and the operation is carried out through the fixed opening on the top of housing 1 to ensure the cleanliness and sealing of the interior of housing 1.
