Description

Technical Field

[0001] This utility model relates to the technical field of sealing structure for biogas storage tanks, and more specifically, to an odor-proof sealing structure for biogas storage tanks. Background Technology

[0002] Biogas slurry is an organic fertilizer, usually formed by the natural decomposition of organic matter (such as aquatic plants, humus, animal excrement, etc.) in paddy fields or swamps. Biogas slurry storage tanks are special containers used for storing and managing biogas slurry. Biogas slurry storage tanks are generally sealed with lids to prevent leakage and odor.

[0003] Existing odor-proof sealing structures for biogas storage tanks require regular manual inspection of the sealing cover for wear, which involves additional labor and resource input and increases the management burden. If the seal fails and is not detected in time, the odor generated by biogas (mainly methane, ammonia, carbon dioxide, and hydrogen sulfide) can easily escape into the air and pollute the environment. In view of this, we propose an odor-proof sealing structure for biogas storage tanks. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an odor-proof sealing structure for biogas storage tanks, so as to solve the technical problem that the current odor-proof sealing structure of biogas storage tanks requires manual periodic inspection of the wear of the sealing cover.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an odor-proof sealing structure for a biogas storage tank, comprising a biogas storage tank, a biogas detection module installed on the outer wall of the biogas storage tank, a can spout fixedly installed on the top of the biogas storage tank, an odor-proof sealing component detachably installed on the can spout, the odor-proof sealing component comprising a cover, and an inner sealing element and an outer sealing element installed at intervals on the cover;

[0006] The nozzle includes an annular cavity, which is connected to a biogas detection module;

[0007] The inner sealing element includes a first sealing ring, and the outer sealing element includes a V-shaped ring fixedly installed outside the ring rim, with the opening of the V-shaped ring facing outward, and a second sealing ring fixedly installed inside the V-shaped ring;

[0008] The first sealing ring and the second sealing ring both have a B-shaped cross-section, and both the first sealing ring and the second sealing ring have elliptical holes arranged in a figure-eight pattern.

[0009] Preferably, both the inner and outer seals are annular, and the inner and outer seals are respectively distributed at the inner and outer ends of the annular cavity, and are respectively sealed to the inner and outer edges of the nozzle.

[0010] Preferably, the nozzle includes a threaded neck fixedly installed on the top of the biogas storage tank, and an annular basin is fixedly connected to the outside of the threaded neck, forming an annular cavity between the threaded neck and the annular basin.

[0011] Preferably, the cover includes a threaded cover that can be connected to a threaded neck, and the outer edge of the closed end of the threaded cover is integrally connected with an annular rim.

[0012] Preferably, the inner seal further includes an inner gasket fixedly installed in the middle of the inner sidewall of the threaded cover, and an inner sealing ring is connected to the outside of the inner gasket, with the first sealing ring installed at the outer root of the inner sealing ring.

[0013] Preferably, an outer sealing ring is fixedly installed at the other end of the V-shaped ring, and a sheet-like sealing ring is installed on the inner side wall of the outer sealing ring. The sheet-like sealing ring has several pieces and is arranged at intervals.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a double-sealed odor-proof sealing component with an internally set annular cavity in the nozzle. The inner and outer sealing parts of the lid cooperate with the nozzle to form a sealed annular cavity. When the inner sealing part is damaged, the odor in the biogas storage tank overflows into the annular cavity and is detected by the biogas detection module connected to the annular cavity. This greatly reduces the occurrence of odor leakage due to untimely inspection by staff or damage to the sealing parts, and solves the problem that the existing odor-proof sealing structure of biogas storage tanks requires manual periodic inspection of the wear of the sealing cover.

[0016] 2. This utility model also incorporates a V-shaped ring with an outward-facing opening on the outer sealing element. The V-shaped ring presses against the outside of the ring basin, creating a rigid seal. The first and second sealing rings, both with B-shaped cross-sections, have elliptical holes arranged in a figure-eight pattern within them. During compression, these elliptical holes deform along the compression direction, causing the B-shaped first and second sealing rings to be squeezed out to both sides, increasing the sealing area. This provides a reliable sealing effect under rotation, movement, or vibration, preventing liquid or gas leakage. It can automatically adjust under pressure changes to maintain good sealing performance, further solving the problem of existing odor-proof sealing structures for biogas storage tanks requiring regular manual inspection of the sealing cover's wear.

[0026] like Figures 1 to 4 As shown, the present invention relates to an odor-proof sealing structure for a biogas storage tank, including a biogas storage tank 1, a biogas detection module 2 installed on the outer wall of the biogas storage tank 1, a can spout 3 fixedly installed on the top of the biogas storage tank 1, an odor-proof sealing component 4 detachably installed on the can spout 3, the odor-proof sealing component 4 including a cover 5, and an inner sealing element 6 and an outer sealing element 7 installed at intervals on the cover 5;

[0027] The nozzle 3 includes an annular cavity 303, which is connected to the biogas detection module 2;

[0028] The inner sealing element 6 includes a first sealing ring 603, and the outer sealing element 7 includes a V-shaped ring 705 fixedly installed outside the ring 502, with the opening of the V-shaped ring 705 facing outward, and a second sealing ring 703 fixedly installed inside the V-shaped ring 705.

[0029] Both the first sealing ring 603 and the second sealing ring 703 have a B-shaped cross-section. Both the first sealing ring 603 and the second sealing ring 703 have elliptical holes 704 arranged in a figure-eight pattern. This utility model uses a double-sealed odor-proof sealing component 4 in conjunction with a can spout 3 with an internal annular cavity 303. The inner sealing element 6 and the outer sealing element 7 of the cover 5 cooperate with the can spout 3 to form a sealed annular cavity 303. When the inner sealing element 6 is damaged, the odor in the biogas storage tank 1 overflows into the annular cavity 303 and is detected by the biogas detection module 2 connected to the annular cavity 303, which greatly reduces the occurrence of odor overflow due to untimely inspection by staff or damage to the sealing element.

[0030] Furthermore, both the inner seal 6 and the outer seal 7 are annular, and the inner seal 6 and the outer seal 7 are distributed at the inner end and the outer end of the annular cavity 303, respectively. The inner seal 6 and the outer seal 7 are respectively sealed and connected to the inner edge and the outer edge of the nozzle 3.

[0031] Furthermore, the nozzle 3 includes a threaded neck 301 fixedly installed on the top of the biogas storage tank 1. An annular basin 302 is fixedly connected to the outside of the threaded neck 301. An annular cavity 303 is formed between the threaded neck 301 and the annular basin 302. An annular cavity 303 is provided between the inner seal 6 and the outer seal 7. Whether the inner seal 6 is in good condition is detected by whether there is any odor leaking out of the annular cavity 303.

[0032] Furthermore, the cover 5 includes a threaded cover 501, which can be connected to the threaded neck 301. The outer edge of the closed end of the threaded cover 501 is integrally connected with an annular rim 502, which facilitates opening or closing the cover.

[0033] Furthermore, the inner sealing element 6 also includes an inner gasket 601 fixedly installed in the middle of the inner sidewall of the threaded cover 501. An inner sealing ring 602 is connected to the outside of the inner gasket 601. A first sealing ring 603 is installed at the outer root of the inner sealing ring 602. When the threaded cover 501 is screwed onto the outside of the thread neck 301, the inner sealing ring 602 is inserted into the threaded cover 501 and sealed to the inner sidewall of the threaded cover 501. The B-shaped first sealing ring 603 is pressed on the top of the threaded cover 501 to achieve the sealing effect of the inner ring.

[0034] Furthermore, an outer sealing ring 701 is fixedly installed at the other end of the V-shaped ring 705. A sheet-like sealing ring 702 is installed on the inner wall of the outer sealing ring 701. The sheet-like sealing ring 702 has several pieces arranged at intervals. When the threaded cap 501 is screwed onto the outside of the threaded neck 301, the outer sealing ring 701 is sealed and connected to the outside of the ring basin 302 through the several sheet-like sealing rings 702 arranged at intervals on the inner wall. The B-shaped second sealing ring 703 is pressed on the top of the ring basin 302 to achieve the sealing effect of the outer ring.

[0035] Working Principle: This embodiment provides an odor-proof sealing structure for a biogas storage tank. In use, the odor-proof sealing component 4 with a double-sealed structure works in conjunction with the spout 3, which has an internal annular cavity 303. The inner sealing element 6 and outer sealing element 7 of the cover 5 cooperate with the spout 3 to form a sealed annular cavity 303. When the inner sealing element 6 is damaged, odorous gas from the biogas storage tank 1 overflows into the annular cavity 303 and is detected by the biogas detection module 2 connected to the annular cavity 303. This greatly reduces the occurrence of odor leakage due to untimely inspection by staff or damage to the sealing element. Furthermore, a V-shaped ring 705 with an outward-facing opening is designed on the outer sealing element 7 to further prevent odor leakage. 705 presses against the outside of the ring basin 302, compressing the outside of the ring basin 302 to form a rigid seal. The first sealing ring 603 and the second sealing ring 703 are designed with a B-shaped cross-section. Both the first sealing ring 603 and the second sealing ring 703 have elliptical holes 704 arranged in a figure-eight pattern. During compression, the elliptical holes 704 deform along the compression direction, and the B-shaped first sealing ring 603 and the second sealing ring 703 are squeezed out to both sides, increasing the sealing area. This provides a reliable sealing effect under rotation, movement, or vibration, preventing liquid or gas leakage. It can automatically adjust under pressure changes to maintain good sealing performance. Yes, normally, the odor-proof sealing assembly 4 is threaded onto the outside of the can spout 3. When the threaded cap 501 is screwed onto the outside of the threaded neck 301, the inner sealing ring 602 is inserted into the threaded cap 501 and seals against the inner wall of the threaded cap 501. The B-shaped first sealing ring 603 is pressed against the top of the threaded cap 501, achieving an inner ring seal. The V-shaped ring 705 with its opening facing outwards presses against the outside of the ring basin 302, compressing the outside of the ring basin 302 to form a rigid seal. The outer sealing ring 701 is sealed to the outside of the ring basin 302 by several sheet-like sealing rings 702 arranged at intervals on the inner wall. The B-shaped second sealing ring 703 is pressed against the top of the ring basin 302, achieving an outer ring seal. The inner seal 6 and outer seal 7 of the body 5 cooperate with the nozzle 3 to form a sealed annular cavity 303. When the inner seal 6 is damaged, the odorous gas in the biogas storage tank 1 overflows into the annular cavity 303 and is detected by the biogas detection module 2. The staff can quickly know that the inner seal 6 is damaged and the odorous gas is leaking, and can quickly repair and replace it. The biogas detection module 2 includes a gas collection box that is connected to the annular cavity 303 through a pipeline. The detection probe of the gas detector extends into the gas collection box. When the gas collection box and the annular cavity 303 are detected to have leaked odorous gas, a buzzer will sound an alarm (the biogas detection module 2 is an existing product on the market and is connected to an external switch and an external power supply).
