Abstract
Description
Technical Field
[0001] This utility model relates to the field of deodorization device technology, and in particular to a deodorization device for constant temperature fermentation of agricultural and livestock manure. Background Technology
[0002] Agricultural animal husbandry refers to the production method of obtaining animal products such as meat, eggs, and milk through artificial animal raising in agricultural production. These products are essential for daily human life. However, artificial animal raising generates a large amount of manure, which requires constant-temperature fermentation. The efficient treatment and convenient maintenance of the odorous gases (containing ammonia, hydrogen sulfide, methane, etc.) produced during fermentation has long been a challenge for the industry. Therefore, deodorization devices are needed to treat these odors. Traditional deodorization devices have two major problems: First, the fixing structure of deodorization filter devices is complex. Activated carbon or filter layers are usually fixed with bolts and clamps, requiring individual bolt removal for replacement, which is time-consuming and easily causes wear on the seals. Some designs simplify installation through unidirectional snap-fit, but lack bidirectional limiting capability, leading to vibration displacement or seal failure.
[0003] Secondly, there is a bottleneck in deodorization efficiency. Current technologies have limited adsorption capacity for ammonia with a single activated carbon layer, while biological filter media requires sufficient contact with the gas to achieve degradation. Existing devices often employ single-stage filtration or simple stacking of filter layers, resulting in poor gas degradation performance.
[0004] To overcome the above-mentioned shortcomings, the inventors invented a deodorizing device for constant-temperature fermentation of agricultural and livestock manure. Utility Model Content
[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a deodorizing device for constant-temperature fermentation of agricultural and livestock manure. This device eliminates the need for bolts and pressure plates to fix activated carbon or filter layers, and also eliminates the simplified installation of unidirectional buckles, providing bidirectional limiting capability. Furthermore, it eliminates the use of a single activated carbon layer and instead employs multi-stage filter layers to achieve efficient absorption of ammonia.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A deodorizing device for constant-temperature fermentation of agricultural and livestock manure includes a deodorizing device installed inside a deodorizing pipe. The deodorizing pipe is movably installed at the top of the fermentation tank. A limiting groove is symmetrically reserved on the outer side of the deodorizing pipe. An elastic fixing device is installed on the outer wall of the deodorizing pipe adjacent to the limiting groove. A fixing ring is detachably installed at the top of the deodorizing pipe. Fixing plates are correspondingly installed on both sides of the fixing ring. The width of the fixing plate is smaller than the width of the limiting groove. A striker is horizontally installed on the outer side of the fixing plate.
[0007] As a further implementation, a fixing pin is installed horizontally on the inner wall of the deodorizing pipe, and a deodorizing device is placed on the fixing pin.
[0008] As a further implementation, the deodorization device includes upper and lower filter boxes. The upper filter box contains EM bacteria and wood chip filler, while the lower filter box contains activated carbon.
[0009] As a further implementation, a buckle is installed along the outer wall of the deodorizing pipe near the bottom of the limiting groove, and a movable rod is installed at the bottom of the fixing plate.
[0010] As a further implementation, the coating material for the inner wall of the deodorizing pipe is PFA.
[0011] As a further implementation, the elastic fixing device includes a fixing box and a spring arranged in a mirror image, and a limiting ball, with a groove corresponding to the bottom of the top of the firing pin.
[0012] As a further implementation, the groove can fit and accommodate the limiting ball.
[0013] As a further implementation, a top filter box is attached to the top of the upper filter box.
[0014] The beneficial effects of this utility model are as follows: This utility model uses a deodorizing device installed inside a deodorizing pipe, which is movably installed at the top of the fermentation tank. A fixing ring is detachably installed at the top of the deodorizing pipe, and fixing plates are installed on both sides of the fixing ring. The width of the fixing plate is smaller than the width of the limiting groove. A striker is horizontally installed on the outside of the fixing plate, which realizes the quick and efficient fixing of the deodorizing device. When it is no longer needed to be replaced, it is not necessary to remove the bolts one by one, which facilitates the installation and removal of the deodorizing device. Attached Figure Description

[0017] Example 1
[0018] This embodiment provides a deodorization device for constant-temperature fermentation of agricultural and livestock manure, such as... Figure 1-7 As shown, the system includes a deodorization device 1, which is installed inside a deodorization pipe 2. The deodorization pipe 2 serves as the core channel for odor treatment and is connected to the top of the fermentation tank 3. It guides the odor generated during fermentation through the deodorization device 1. The deodorization pipe 2 is movably mounted on the top of the fermentation tank 3. Symmetrical limiting grooves 4 are provided on the outer side of the deodorization pipe 2. An elastic fixing device 5 is provided on the outer wall of the deodorization pipe 2 adjacent to the limiting groove 4 to achieve quick positioning and locking of the fixing ring 6. The elastic fixing device 5 includes a fixing box 51 and a spring 52 arranged in a mirror image, as well as a limiting ball 53. The fixing ring 6 is detachably mounted on the top of the deodorization pipe 2. Fixing plates 7 are correspondingly mounted on both sides of the fixing ring 6. The limiting groove 4 is used to cooperate with the fixing plate 7 to avoid installation misalignment. The width of the fixing plate 7 is smaller than the width of the limiting groove 4. A striker 8 is horizontally mounted on the outer side of the fixing plate 7. Grooves 14 are correspondingly mounted on the top and bottom of the striker 8. The grooves 14 can fit and accommodate the limiting ball 53. This design is to achieve better horizontal locking of the striker 8. The elastic fixing device 5 locks the firing pin 8 in the limiting groove 4 with elastic force, achieving boltless fixing and simplifying the disassembly process.
[0019] The fixing ring 6 covers the top of the deodorizing pipe 2. The fixing ring 6 ensures stability by pressing down the activated carbon deodorizing layer (or filter box). At the same time, the fixing plate 7 and the limiting groove 4 cooperate to achieve a stable connection. The fixing ring 6 also serves as a force point during disassembly.
[0020] The width of the fixing plate 7 is smaller than that of the limiting groove 4, which makes it easier to insert and then rotate.
[0021] Several fixing pins 9 are horizontally arranged on the inner wall of the deodorizing pipe 2. The deodorizing device 1 is placed on the fixing pins 9. The fixing pins 9 are horizontally fixed to the inner wall of the deodorizing pipe 2 and support the deodorizing device 1, ensuring its stable position and easy removal and replacement. In the prior art, a ring is usually placed at the outlet, and the deodorizing device 1 is then supported on the ring. The drawback of this design is that the cross-section of the ring will block the contact between the gas and the deodorizing device 1. The fixing pin 9 design of this application increases the contact area between the deodorizing device 1 and the gas, thus improving the contact efficiency.
[0022] The deodorization device 1 includes upper and lower filter boxes. The upper filter box 10 contains EM bacteria and sawdust filler, while the lower filter box 11 contains activated carbon. The function of the upper filter box 10 (containing EM bacteria and sawdust filler) is as follows: EM bacteria (such as lactic acid bacteria and yeast) biodegrade and decompose ammonia and hydrogen sulfide in odorous gases; sawdust provides a carrier for microorganisms, prolonging the reaction time and enhancing the deodorization effect. The function of the lower filter box 11 (containing activated carbon) is to physically adsorb residual small-molecule odorous gases (such as methane and thiols) and trace amounts of harmful substances. Both the upper filter box 10 and the lower filter box 11 are made of PTFE material.
[0023] Below the limiting groove 4, a buckle 13 is installed along the outer wall of the deodorizing pipe. A movable rod 12 is installed at the bottom of the fixed plate 7 (specifically, the movable rod 12 is hinged to the outer wall of the fixed plate 7). A stop block 16 is installed below the movable rod 12 (the stop block 16 is fixedly installed on the outer wall of the fixed plate 7). The stop block 16 prevents the movable rod 12 from rotating downwards, so the movable rod 12 can move upwards along the outer wall of the fixed plate 7. When the bottom of the fixed plate 7 is close to the bottom of the limiting groove 4, the buckle 13 includes a locking groove 131 and an elastic buckle 132. The elastic buckle 132 is connected to the center of the locking groove 131 by a spring 52. The elastic buckle 132 can pass through the movable rod 12 and lock the movable rod 12 in the locking groove 131. This design achieves vertical displacement limitation, while ensuring that the buckle 13 can move along the movable rod 12 in the X-plane. After movement, it is convenient for the firing pin 8 to lock with the elastic fixing device 5.
[0024] The inner wall coating material of deodorizing pipe 2 is PFA. PFA is coated on the inner wall of deodorizing pipe 2 to prevent acidic components (such as hydrogen sulfide) in odorous gas from corroding the pipe.
[0025] Example 2
[0026] The difference between this embodiment and Embodiment 1 is that a top filter box is attached above the upper filter box 10. The top filter box is made of PTFE material and contains granular zeolite. Gas is allowed to pass from bottom to top, sequentially through the lower filter box 11, the upper filter box 10, and the top filter box. The granular zeolite has a high absorption efficiency for ammonia (which has a strong odor), reducing the unpleasant smell in the gas.
[0027] The other design schemes in this embodiment are the same as those in Embodiment 1.
[0028] The Chinese patent document CN219942499U, "Organic Fermentation Deodorization Equipment," discloses an organic fertilizer fermentation deodorization device that uses an air pump to draw outside air into the intake pipe through an extraction pipe, thereby reducing the odor produced by anaerobic respiration and decreasing the amount of activated carbon used in the activated carbon box. However, CN219942499U does not utilize other substances to increase the odor absorption efficiency and increases power consumption. This application, through its multi-layer filter box design, consumes virtually no power while achieving highly efficient odor absorption; therefore, it is more energy-efficient.
[0029] The length, height, and curvature of the lines of the elastic fixing device 5, the firing pin 8, and the buckle 13 in the attached diagram are for illustrative purposes only. Those skilled in the art can make adaptive adjustments according to actual usage.
[0030] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
