Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Example one
As shown in fig. 1-2, an embodiment of the present invention provides a detachable livestock and poultry manure compost ventilation system, including:
the composting device comprises a main pipe 1, wherein the main pipe 1 is provided with a plurality of branch pipes 11 arranged at intervals along the height direction, the main pipe 1 is formed by detachably connecting a plurality of pipe sections 12, the branch pipes 11 are detachably arranged on the main pipe 1, the branch pipes 11 are provided with a plurality of vent holes 111, the branch pipes 11 inject airflow into composting materials through the vent holes 111, and the airflow amount injected into the composting materials by different branch pipes 11 is different;
and the air supply device 2 is connected with the main pipe 1 so as to input airflow into the main pipe 1, and the air supply device 2 comprises a frequency conversion fan, a blower and other conventional air supply devices.
It should be noted that, in the present embodiment, one row, two rows or more rows of vent holes 111 are provided on the branch pipe 11 according to actual requirements.
This embodiment during operation, air supply arrangement 2 is to being responsible for 1 interior input air current, the air current gets into and can follow being responsible for 1 after being responsible for and flow, the air current can get into each branch pipe 11 along being responsible for 1 mobile in-process, the air current can follow branch pipe 11 after getting into each branch pipe 11 and flow and penetrate into the compost material with fluidic form through ventilation hole 111 on it, the air current jets into inside each position that can permeate the compost material of compost material, thereby required oxygen when providing its compost to the compost material.
The main pipe 1 of the embodiment of the invention is provided with a plurality of branch pipes 11 with different heights, when in use, the branch pipes 11 can be inserted into the compost material pile body to inject airflow into the compost material along the height direction of the compost material pile body, and the airflow injected into the compost material can permeate inside the compost material, thereby supplying oxygen required by the fermentation of the compost material. Because each branch pipe 11 only supplies air corresponding to the composting materials with a small height, the speed attenuation degree of the air flow emitted by each branch pipe 11 after the air flow enters the composting materials is small, which is beneficial to the full penetration of the air flow emitted by each branch pipe 11 in the composting materials corresponding to the branch pipe 11, thereby ensuring that the composting materials corresponding to each branch pipe 11 can obtain sufficient oxygen supply. Therefore, the embodiment of the invention can ensure that all compost materials can obtain sufficient oxygen supply, the compost materials are quickly fermented and decomposed, and the odor emission in the composting process is reduced.
It should be noted that, because the ventilation volume required by different compost materials and the attenuation degree of the air flow after being injected into the compost materials are different, the distance between the adjacent branch pipes 11 can be adjusted according to the actual situation in practical application of the embodiment, wherein the distance between the adjacent branch pipes 11 is inversely proportional to the moisture content of the compost materials, the required ventilation volume and the attenuation degree of the air flow after being injected into the compost materials. When the moisture content of the compost materials is high, the required ventilation quantity is large or the attenuation of air flow after the air flow is injected into the compost materials is serious, the distance between the adjacent branch pipes 11 can be properly reduced so as to ensure that the compost materials can obtain sufficient oxygen supply and the compost can be smoothly carried out; when the amount of ventilation required for the composting material is small or the attenuation of the air flow after it has entered the composting material is light, the distance between adjacent branches 11 can be increased appropriately, so that the number of branches 11 is reduced on the premise of ensuring a sufficient oxygen supply to the composting material, and the manufacturing costs of the ventilation system are reduced as much as possible.
Preferably, the distance between adjacent branch pipes 11 is between 0.4m and 0.6m.
It will be appreciated that the distance between adjacent legs 11 may be determined by such practical factors as the moisture content of the compost material, the amount of ventilation required and the degree of attenuation of the air stream after it has been injected into the compost material. For example, for compost materials requiring a large ventilation volume and having a high water content, the distance between the adjacent branch pipes 11 may be set to 0.4m, and for compost materials requiring a small ventilation volume and having a low water content, the distance between the adjacent branch pipes 11 may be set to 0.6m.
Specifically, as shown in fig. 1, the main pipe 1 of the present embodiment is formed by connecting a plurality of pipe segments 12, and the adjacent pipe segments 12 and the branch pipes 11 are connected by pipe connectors such as a two-way pipe 6 and a three-way pipe 7. Wherein the length of each pipe section 12 is close to the distance between adjacent branch pipes 11, and the distance between adjacent branch pipes 11 can be adjusted by controlling the length of each pipe section 12.
When the compost materials are piled in the pile body 3, the density of the materials in the pile body 3 is gradually increased downwards along the height direction of the materials due to the action of gravity, the density and the ventilation resistance of the materials on the upper layer in the pile body 3 are small, the porosity is large, and the density and the ventilation resistance of the materials on the lower layer are large, and the porosity is small. Consequently, the ventilation volume that 3 upper compost materials of heap body obtained is abundant and the not enough condition of ventilation volume that 3 bottom compost materials of heap body obtained probably appears when compost ventilation system supplies air to the compost material, and the fermentation speed of upper compost material is greater than the fermentation speed of lower floor compost material this moment, and this can make upper and lower floor material can't become thoroughly decomposed simultaneously.
Because different branch pipes 11 of the embodiment of the invention can inject different air flows into the compost materials, the ventilation quantity of each branch pipe 11 can be adjusted when the device is used, so that the effects of small ventilation quantity of the upper layer branch pipe 11 and large ventilation quantity of the lower layer branch pipe 11 are achieved, and accurate air supply is realized according to the ventilation quantity required by the compost materials at different heights in the compost body 3, thus the embodiment of the invention can ensure that the ventilation quantity of the upper layer of the compost materials is small, the ventilation quantity of the lower layer is large, and the effect of simultaneously decomposing the materials at different heights is achieved.
Further, the pipe diameters of the branch pipes 11 decrease gradually from bottom to top along the height direction of the main pipe 1.
It will be appreciated that the larger the pipe diameter of the branch pipe 11, the greater its ventilation volume. This embodiment makes the air volume of each branch pipe 11 also by reducing in proper order down through the pipe diameter that reduces branch pipe 11 from bottom to top in proper order, it is little to reach 11 air volumes of upper branch pipe, the big effect of 11 air volumes of lower floor's branch pipe, this can guarantee that upper compost material air volume is little, lower floor's material air volume is big, make compost material homoenergetic on the co-altitude in the heap body 3 obtain sufficient oxygen supply and can thoroughly decomposed simultaneously, avoid the compost material because of the uneven problem that the speed of thoroughly decomposing is inconsistent appears in the density distribution that gravity causes and lead to.
Preferably, the pipe diameters of the branch pipes 11 are sequentially decreased by 2% -5% from bottom to top. The specific decreasing amplitude of the branch pipes 11 is determined according to the type of the compost materials and is in direct proportion to the ventilation volume and the water content. For example, for compost materials requiring a large amount of ventilation and having a high water content, the diameter reduction of the branch pipes 11 may be 5%; for compost materials with smaller required ventilation and lower water content, the diameter reduction of the branch pipes 11 can be 2%.
Of course, the decreasing width of the pipe diameter of the branch pipes 11 is not limited to the above-mentioned width, and other decreasing widths may be set according to the type of the compost material and the like in other embodiments.
Further, the branch pipes 11 are respectively provided with a flow regulating valve 4.
It is understood that the way of changing the ventilation volume of each branch pipe 11 in the present embodiment is not limited to the way of adjusting the pipe diameter of the branch pipe 11 and providing the flow regulating valve 4, but may be implemented in other ways in other embodiments, for example, by adjusting the number or aperture of the ventilation holes 111 on the branch pipe 11.
Furthermore, the main pipe 1 and the branch pipes 11 are respectively provided with a flow meter 5, and the flow meters 5 can detect the air volume in the ventilation process of the main pipe 1 and each branch pipe 11. In the composting process of the embodiment, the ventilation quantity of the main pipe 1 and each branch pipe 11 can be adjusted through the flow regulating valve 4 or the air supply device 2 according to the ventilation quantity required by different materials for composting.
Furthermore, the branch pipe 11 is detachably arranged on the main pipe 1 through connection modes such as threaded connection, clamping connection and the like.
When the composting device is used, after composting of compost materials is completed, all pipe sections can be connected in sequence to form a main pipe, then all branch pipes are connected with the main pipe in sections, the rest parts of all branch pipes are inserted into materials with different heights to vertically ventilate the materials, and after composting reaction is completed, the branch pipes are drawn out and removed to facilitate discharging and feeding next time, so that the composting materials can be vertically ventilated without affecting the feeding and discharging of the materials.
Further, the number of the vent holes 111 of the branch pipes 11 is gradually increased from the end thereof close to the main pipe 1 to the end thereof far from the main pipe 1.
Because the air flow velocity of the air outlet of the branch pipe 11 will gradually decrease along the length direction due to the on-way resistance when the air flow flows in the branch pipe 11, if the ventilation holes 111 of the branch pipe 11 are uniformly distributed from front to back, the air outlet of the whole branch pipe 11 will be non-uniform, and the ventilation effect of the branch pipe 11 will be reduced. When this embodiment passes through, the number of the ventilation holes 111 on the branch pipe 11 is gradually increased from the end close to the main pipe 1 to the end far away from the main pipe 1, so that the ventilation quantity of each part on the branch pipe 11 is more uniform, thereby being favorable for promoting the ventilation effect of the branch pipe 11, and enabling the compost material homoenergetic corresponding to each branch pipe 11 to obtain sufficient oxygen supply.
Example two
As shown in fig. 1, the embodiment of the present invention also provides a composting apparatus comprising a compost heap 3 and a composting ventilating device as described in the first embodiment, a main pipe 1 is provided on one side of the compost heap 3, and branch pipes 11 are extended into the interior of the compost heap 3 to insert composting materials and inject air flow into the composting materials.
