[0002] During the fermentation of manure organic fertilizer, a large amount of gas is produced. This gas not only has an odor, but may also contain some harmful components. If this gas is not discharged and treated in a timely and effective manner, it will not only affect the stability of the fermentation environment, but also pollute the surrounding environment.

[0003] According to the odorless fermentation equipment for organic fertilizer of livestock and poultry manure proposed in Chinese Patent Publication No. CN222758165U, a deodorizing agent is added inside the water washing tank. The odor generated during the fermentation process inside the fermentation tank is drawn into the water washing tank by the air extraction component. After the odor is treated by the deodorizing agent water washing, it is discharged to the outside through the connecting pipe and the exhaust pipe.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-4 As shown, the present invention proposes an exhaust device for fermenting manure organic fertilizer, including a base plate 1, a fermentation tank 2 installed on the top of the base plate 1, a water washing tank 3 located on the left side of the fermentation tank 2 installed on the top of the base plate 1, an air pump 4 installed on the top of the fermentation tank 2, an air inlet of the air pump 4 connected to an air extraction pipe 5 connected to the top of the fermentation tank 2, and an air outlet of the air pump 4 connected to a water washing pipe 6 connected at the other end to the inside of the water washing tank 3. A filter mechanism 7 located on the left side of the water washing tank 3 is provided on the top of the base plate 1.

[0024] In this invention, the fermentation tank 2 can ferment manure organic fertilizer, and the gas generated during fermentation in the fermentation tank 2 can be sent into the water washing tank 3 through the air pump 4, air extraction pipe 5 and water washing pipe 6. The water washing tank 3 contains a deodorizing agent solution. When the gas enters the water washing tank 3, it will pass through the deodorizing agent solution, thereby removing the odor and some water-soluble gases from the gas. The treated gas will enter the filter mechanism 7, and the filter mechanism 7 will filter the treated gas.

[0025] In addition, the top of the washing tank 3 is connected to a water inlet pipe, and the bottom outside of the washing tank 3 is connected to a water outlet pipe. The top of the water inlet pipe is threaded with a cap to seal the top of the water inlet pipe. The water outlet pipe is equipped with a valve to prevent gas from being discharged through the water inlet or water outlet pipe.

[0026] In embodiment 1, the filtration mechanism 7 includes a filter box 71, a connecting pipe 72, a cover plate 73, two vertical plates 74, three slide rails 75, three filter plates 76, a handle 77, two sets of mounting components 78, and an exhaust component 79. The filter box 71 is mounted on the top of the base plate 1. The connecting pipe 72 is connected to the top of the washing tank 3, and the other end of the connecting pipe 72 is connected to the bottom right side of the filter box 71. The cover plate 73 is movably connected to the top of the filter box 71 and is adapted to fit the filter box 71. The top of the filter box 71... A sealing rubber gasket is installed between the bottom of the cover plate 73 and the top of the cover plate 73. Two vertical plates 74 are installed at the bottom of the cover plate 73. Three slide rails 75 are installed between the opposite sides of the two vertical plates 74 and are evenly distributed. Three filter plates 76 are slidably connected to the inside of the three slide rails 75. A handle 77 is installed on the top of the cover plate 73. Two sets of mounting components 78 are respectively set on the front and back of the cover plate 73 for installing the cover plate 73. An exhaust component 79 is set on the outer end face of the filter box 71.

[0027] The treated gas enters the filter box 71 through the connecting pipe 72 and is filtered by the three filter plates 76 inside the filter box 71. It is then discharged through the exhaust assembly 79. After the gas treatment is completed, the cover plate 73 is released from the two sets of mounting components 78. Then, the cover plate 73 is removed by the handle 77, which allows the two vertical plates 74, three slide rails 75, and three filter plates 76 to be removed. At this time, the three filter plates 76 can be quickly replaced by removing them from the three slide rails 75, ensuring the filtration effect of the filtration mechanism 7.

[0028] The three filter plates 76, from bottom to top, are a biological filter plate, a water-absorbing sponge plate, and an activated carbon adsorption plate. The water-absorbing sponge plate absorbs the moisture in the washed gas. The biological filter plate decomposes the residual odorous gas in the washed gas into carbon dioxide and water through microorganisms. The decomposed water falls onto the water-absorbing sponge plate and is absorbed by it. The activated carbon adsorption plate further adsorbs the residual odor substances, so that the gas can be fully filtered, minimizing the harmful substances or odors in the discharged gas.

[0029] It should be noted that the opposite sides of the two vertical plates 74 are slidably connected to the front and rear side walls of the inner cavity of the filter box 71, respectively, and the front and back sides of the filter plate 76 are slidably connected to the left and right side walls of the inner cavity of the filter box 71, respectively. This ensures that the three plates can fully filter the gas after washing and prevent gas from leaking through gaps without being filtered.

[0030] In embodiment two, both sets of mounting components 78 include a top plate 781, mounting blocks 782, mounting grooves 783, connecting blocks 784, and fixing modules 785. The two top plates 781 are respectively mounted on the front and back of the cover plate 73, the two mounting blocks 782 are respectively mounted on the front and back of the filter box 71, the two mounting grooves 783 are respectively opened on the top of the two mounting blocks 782, the two connecting blocks 784 are respectively mounted on the bottom of the two top plates 781 and are slidably connected to the inside of the two mounting grooves 783, and the two sets of fixing modules 785 are respectively disposed on opposite sides of the two mounting blocks 782. The fixing modules 785 are connected to the connecting blocks 784 and are used to fix the connecting blocks 784.

[0031] When installing the cover plate 73, the two vertical plates 74, the three slide rails 75, and the three filter plates 76, the two vertical plates 74 need to be slidably connected to the inside of the filter box 71. At the same time, the bottom of the cover plate 73 should be in contact with the top of the filter box 71. At this time, the two connecting blocks 784 will be slidably connected to the inside of the two mounting slots 783 respectively. The cover plate 73 can be fixed by fixing the two connecting blocks 784 with two sets of fixing modules 785 respectively.

[0032] When it is necessary to remove and replace the three filter plates 76, the fixing module 785 loses its fixation to the connecting block 784, and the cover plate 73, the two vertical plates 74, the three slide rails 75 and the three filter plates 76 can be removed by the handle 77, which facilitates the quick replacement of the three filter plates 76.

[0033] In embodiment three, both sets of fixing modules 785 include threaded grooves 7851, threaded rods 7852, and knobs 7853. The two threaded grooves 7851 are respectively opened on opposite sides of the two connecting blocks 784. The two threaded rods 7852 are respectively movably connected to opposite sides of the two mounting blocks 782 and extend into the two threaded grooves 7851. The two threaded rods 7852 are respectively threadedly connected to the two threaded grooves 7851. The two knobs 7853 are respectively installed on opposite sides of the two threaded rods 7852.

[0034] When it is necessary to remove the cover plate 73, the two vertical plates 74, the three slide rails 75 and the three filter plates 76, turn the knob 7853. The knob 7853 will drive the threaded rod 7852 to rotate. When the threaded rod 7852 disengages from the corresponding threaded groove 7851, the fixing of the connecting block 784 will be lost.

[0035] When installing the cover plate 73, the two vertical plates 74, the three slide rails 75 and the three filter plates 76, simply rotate the knob 7853 in the opposite direction so that the threaded rod 7852 is threadedly connected to the corresponding threaded groove 7851, thereby fixing the connecting block 784 and thus fixing the cover plate 73.

[0036] In embodiment four, the exhaust assembly 79 includes an exhaust pipe 791 and a check valve 792. The exhaust pipe 791 is connected to the left side of the filter box 71 and is located above the filter plate 76. The check valve 792 is installed inside the exhaust pipe 791.

[0037] After the gas is filtered, it will be discharged through the exhaust pipe 791, and the check valve 792 effectively prevents the backflow of outside air, ensuring a stable fermentation environment in the fermentation tank 2, which is conducive to improving the quality of organic fertilizer.

[0038] In Example 5, a drain outlet is provided at the bottom of the outer side of the filter box 71, and a plug is provided on the drain outlet. When there is water inside the filter box 71, the water inside the filter box 71 can be drained through the drain outlet by opening the plug.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
