Description

Technical Field

[0001] This application relates to the field of biogas slurry storage technology, and in particular to a ventilation structure for an isolation shed of a biogas slurry storage tank. Background Technology

[0002] A biogas slurry storage tank is a facility used to store the liquid formed after the fermentation of organic matter in pig manure. Currently, my country mostly uses anaerobic and aerobic processes to treat livestock manure, sterilizing and deodorizing the manure to reduce the concentration of organic matter. The resulting biogas slurry flows into the storage tank for further utilization. The bottom of the storage tank is lined with a PE membrane to prevent leakage. The biogas slurry is temporarily stored in the tank, generally for 150 days before use. To protect the storage tank from rain, an isolation shed is usually added. However, biogas is produced during the storage process. If it is not discharged in time, it may accumulate in the tank, increasing the risk of explosion.

[0003] In the existing technology, the isolation shed includes a supporting frame, a covering and open ventilation windows. The supporting frame ensures the overall stability of the isolation shed, the covering encloses the above-ground part of the supporting frame to block most of the external interference, and the open ventilation windows allow the biogas accumulated in the biogas storage tank to be discharged.

[0004] Regarding the aforementioned technologies, although open ventilation windows can expel biogas over a large area through natural convection, they can easily lead to a large amount of foul odor escaping, exacerbating environmental pollution. Summary of the Invention

[0005] In order to reduce the leakage of odors during ventilation, this application provides a ventilation structure for the isolation shed of a biogas slurry storage tank.

[0006] The ventilation structure for the isolation shed of a biogas slurry storage tank provided in this application adopts the following technical solution:

[0007] A ventilation structure for an isolation shed of a biogas slurry storage tank includes an arched support, a horizontal support, a covering, and ventilation windows, wherein the arched support and the horizontal support are each provided with a plurality of supports.

[0008] The arched support members are distributed horizontally and are all vertically arranged; the horizontal support members are distributed horizontally along the length of the arched support members and are all installed on the arched support members; and the arched support members are interconnected through the horizontal support members.

[0009] The cover is installed on several arched supports and several horizontal supports, and the cover encloses the above-ground parts of each arched support and each horizontal support, and the cover encloses and forms a shielding chamber, which is used to set up a biogas slurry storage tank.

[0010] The ventilation windows are provided in several parts, and the ventilation windows are divided into two parts. The distribution direction of the two parts of ventilation windows is consistent with the distribution direction of each arched support member, and the two parts of ventilation windows are respectively located at both ends of the ventilation structure of the isolation shed of the biogas slurry storage tank.

[0011] The ventilation window includes several ventilation strips and a mounting frame. The ventilation strips are arranged vertically and surrounded by the mounting frame. The ventilation strips are rotatably fitted to the mounting frame. The ventilation window forms an openable and closable ventilation gap by rotating the ventilation strips. The shielding chamber is connected to the atmosphere through the open ventilation gap.

[0012] By adopting the above technical solution, when the biogas concentration in the shielded chamber is too high, the ventilation strip can be rotated to achieve directional ventilation by utilizing the ventilation gap formed after the rotation of the ventilation strip. The airflow is divided into multiple small streams by the ventilation strip and then flows out from the ventilation gap. This ensures that biogas and harmful gases are effectively discharged while maintaining ventilation, and also reduces odor leakage through the spacing of the ventilation strip.

[0013] Optionally, the ventilation strip is further provided with several adjusting synchronous pulleys, which are respectively installed on each ventilation strip. The adjusting synchronous pulley at the bottom is provided with a first bevel gear, and the ventilation strips in the middle position are provided with two adjusting synchronous pulleys. The adjusting synchronous pulleys on the same ventilation strip are connected to each other through transmission. The mounting frame is provided with several adjusting synchronous belts and adjusting knobs. Adjacent adjusting synchronous pulleys are engaged through adjusting synchronous belts. The adjusting knob is provided with a second bevel gear, and the first bevel gear and the second bevel gear are engaged with each other.

[0014] By adopting the above technical solution, the opening direction of the ventilation strip can be adjusted by rotating the adjustment knob, thereby adjusting the ventilation gap and changing the ventilation gap to meet the needs of opening and closing the ventilation gap in different scenarios.

[0015] Optionally, the arched support member is provided with a plurality of first positioning members, which are horizontally distributed along the length direction of the arched support member;

[0016] The first positioning member has a first slot and a second slot. The first positioning member is installed on the arched support member through the first slot. The horizontal support member is fixedly connected to the arched support member through the second slot of the first positioning member. The opening direction of the first slot is opposite to the opening direction of the second slot.

[0017] By adopting the above technical solution, the multi-dimensional positioning of the first and second slots can effectively improve the installation speed of the arch support and the horizontal support.

[0018] Optionally, the arch support member is provided with two second positioning members, which are located at both ends of the arch support member respectively. The top of the second positioning member is provided with a positioning groove, which extends along the distribution direction of each arch support member. The second positioning member is used to accommodate the bottom of the arch support member.

[0019] By adopting the above technical solution, the second positioning component not only enables the arched support to be quickly positioned during installation, but also makes several arched support components parallel to each other, which is beneficial for the subsequent installation of the covering component.

[0020] Optionally, the second positioning member is provided with a plurality of fixing posts, all of which are fixedly connected to the bottom of the second positioning member and are buried in the ground.

[0021] By adopting the above technical solutions, it is beneficial to improve the stability of the isolation shed.

[0022] Optionally, the top of the cover is arched.

[0023] By adopting the above technical solutions, it is possible to avoid the accumulation of rainwater and dust on the top of the isolation shed during the rainy season or dusty weather.

[0024] Optionally, the cover is made transparent.

[0025] By adopting the above technical solution, staff can observe the purification status of sludge inside the biogas slurry storage tank without entering the tank.

[0026] Optionally, each of the two ventilation windows is provided with an entrance door.

[0027] By adopting the above technical solution, staff can enter the shielded chamber through the entrance door and purify the biogas slurry storage tank.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When the biogas concentration in the shielded chamber is too high, the ventilation strips can be rotated to achieve directional ventilation by utilizing the ventilation gaps formed after the rotation of the ventilation strips. The airflow is divided into multiple fine streams by the ventilation strips and then flows out from the ventilation gaps. This ensures that biogas and harmful gases are effectively discharged while maintaining ventilation, and also reduces odor leakage through the spacing of the ventilation strips.

[0030] 2. The opening direction of the ventilation strip can be adjusted by rotating the adjustment knob, thereby adjusting the ventilation gap and changing the ventilation gap to meet the opening and closing needs of the ventilation gap in different scenarios;

[0031] 3. The second positioning component not only enables the arched support to be quickly positioned during installation, but also ensures that several arched support components are parallel to each other, which is beneficial for the subsequent installation of the covering component.

[0041] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0042] Example 1:

[0043] Embodiment 1 of this application discloses a ventilation structure for an isolation shed of a biogas slurry storage tank. (Refer to...) Figure 1 and Figure 2 The ventilation structure of the biogas slurry storage tank isolation shed includes an arched support 1, a horizontal support 2, a covering 3, and a ventilation window 4.

[0044] Several arched support members 1 are distributed horizontally and are all vertically arranged, and several horizontal support members 2 are distributed along the arch length direction of the arched support members 1 and are all horizontally arranged.

[0045] Reference Figure 3 The arched support 1 is further provided with several first positioning elements 11 and several second positioning elements 12. The first positioning elements 11 are rectangular parallelepipeds, each having a first slot 101 and a second slot 102, located at opposite ends of the first positioning element 11. The opening direction of the first slot 101 is opposite to that of the second slot 102, and the fixing angles of the first slot 101 and the second slot 102 are perpendicular to each other. The first slot 101 is used for fixing the arched support 1, and the second slot 102 is used for fixing the horizontal support 2. The multi-dimensional positioning via the first slot 101 and the second slot 102 effectively improves the installation speed and stability of the arched support 1 and the horizontal support 2.

[0046] Reference Figure 4 Two second positioning members 12 are provided, located on either side of the arched support member 1, and both second positioning members 12 are rod-shaped and parallel to each other. A positioning groove 103 is formed at the top of each second positioning member 12, extending along its length to both ends and penetrating through it. Several arched support members 1 are vertically arranged along the length of the second positioning members 12 in the positioning groove 103 and fixedly installed therein by welding, ensuring that the arched support members 1 are parallel to each other in the vertical direction during installation and use. The second positioning members 12 ensure the stability of the overall structure and facilitate the erection of the support assembly. Several fixing columns 13 are fixedly installed at the bottom of the second assembly by welding, distributed along the length of the second positioning members 12. During the erection of the support assembly, the fixing columns 13 will be buried in the ground to provide overall support for the isolation shed.

[0047] Reference Figure 5The covering component 3 is fixedly installed on several arched support components 1 and several horizontal support components 2, and the covering component 3 encloses the above-ground parts of each arched support component 1 and each horizontal support component 2, forming a shielding chamber 301. The shielding chamber 301 is used to house the biogas slurry storage tank, allowing the biogas slurry storage tank to block most of the external interference. The top of the covering component 3 is arched, preventing rainwater or dust from accumulating on the top of the isolation shed during the rainy season or dusty weather. Both the top covering component 3 and the vertical covering component 3 are made of transparent fiberglass. Fiberglass is translucent, allowing light to pass through the shed, enabling operators to view the storage tank during the day without additional lighting. Furthermore, the material itself has good weather resistance, able to withstand common outdoor weather conditions such as sun, rain, wind, and snow.

[0048] Reference Figure 5 and Figure 6 There are two ventilation windows 4, and the distribution direction of the two ventilation windows 4 is consistent with the distribution direction of each arched support 1. The two ventilation windows 4 are located at both ends of the ventilation structure of the isolation shed of the biogas slurry storage tank to facilitate convection. In addition, an entrance door 41 is provided next to the ventilation window 4, through which staff can enter the shielded chamber 301.

[0049] Reference Figure 6 and Figure 7 The ventilation window 4 includes four ventilation strips 42 and a mounting frame 43. The four ventilation strips 42 are arranged vertically and enclosed by the mounting frame 43. All four ventilation strips 42 are rotatably fitted to the mounting frame 43. The ventilation window 4 forms an openable and closable ventilation gap 401 through the rotation of the ventilation strips 42. The shielding chamber 301 is connected to the atmosphere through the open ventilation gap 401. Although the ventilation gap 401 allows odorous gases to escape along with biogas and harmful gases through natural convection, the airflow of biogas, harmful gases, and odorous gases is divided into multiple fine streams by the ventilation strips 42. These fine streams effectively reduce the leakage of accompanying odorous gases.

[0050] The implementation principle of the ventilation structure of the isolation shed for a biogas storage tank in Embodiment 1 of this application is as follows: When the biogas concentration in the shielded chamber 301 is too high, the rotatable ventilation strips 42 achieve directional ventilation by utilizing the ventilation gaps 401 formed by the opened ventilation strips 42 after rotation. The airflow carrying biogas, harmful gases, and odors is divided into multiple fine streams by the ventilation strips 42 and discharged to the outside, thereby reducing the concentration of biogas and harmful gases in the shielded chamber 301 in real time. In addition, the airflow carrying odors is divided into multiple fine streams by the ventilation strips 42, which can also effectively reduce the overflow of odors during ventilation.

[0051] Example 2:

[0052] Embodiment 2 of this application discloses a ventilation window, which, in addition to all the technical features of Embodiment 1, also includes the following technical features:

[0053] Reference Figure 7 and Figure 8 Each of the four ventilation strips 42 is equipped with an adjusting synchronous pulley 44, which is fixedly installed on each ventilation strip 42 and distributed vertically. The two middle ventilation strips 42 each have two corresponding adjusting synchronous pulleys 44, and the two adjusting synchronous pulleys 44 on the same ventilation strip 42 are coaxially and fixedly connected. The mounting frame 43 has three adjusting synchronous belts 46 and an adjusting knob 47. The three adjusting synchronous belts 46 are gear-engaged with each of the two adjacent adjusting synchronous pulleys 44, so that the ventilation strips 42 can rotate synchronously through the adjusting synchronous belts 46. The adjusting synchronous pulley 44 at the bottom is coaxially fixedly mounted with a first bevel gear 45, and the adjusting knob 47 is coaxially fixedly mounted with a second bevel gear 48. The first bevel gear 45 and the second bevel gear 48 mesh with each other, and the gear meshing drives the rotation between the adjusting synchronous belts 46 and the adjusting synchronous pulleys 44, thereby causing the ventilation strips 42 to rotate.

[0054] By adopting the above technical solution, by rotating the adjustment knob, the second bevel gear 48 first drives the first bevel gear 45 to rotate, then the first bevel gear 45 drives the adjusting synchronous wheel 44 to rotate, and finally the adjusting synchronous belt 46 between the two adjacent ventilation strips 42 transmits power to drive the adjusting synchronous wheel 44 to rotate, thereby realizing the adjustment of the opening state of the ventilation gap 401.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
