Abstract
Description
Technical Field
[0001] This utility model relates to the field of deodorization technology for livestock and poultry manure fermentation, specifically to a deodorization device for livestock and poultry manure fermentation. Background Technology
[0002] Fecal treatment involves killing pathogens and parasite eggs in feces, transforming it from harmful to harmless. Methods include storage, fermentation, sedimentation, composting, and the application of chemicals. Well-rotted feces, after treatment, can be used as fertilizer, which is beneficial for the absorption and utilization of crop roots. However, the treatment of feces often produces a large amount of gas, which contains hydrogen sulfide, methane, skatole, etc., resulting in an unpleasant odor and harm to the body. Therefore, deodorization devices are often needed to purify the odor.
[0003] A Chinese patent (publication number: CN217459177U) discloses a deodorizing device for fermenting livestock and poultry manure, which includes a fixing ring with equally spaced fixing holes on the top outer wall. A filtering mechanism is provided below the fixing ring. The filtering mechanism includes a hemispherical filter cover, a connecting ring welded to the top outer wall of the filter cover, an activated carbon filter screen overlapping the lower inner wall of the filter cover, a dust removal plate overlapping the middle inner wall of the filter cover, a silica gel drying plate overlapping the upper inner wall of the filter cover, and an air inlet pipe sleeved on the bottom inner wall of the filter cover. An air supply pipe is connected to the bottom outer wall of the air inlet pipe through a flange.
[0004] During the use of the above equipment, the gas is first filtered through a multi-layer filter plate. Then, the gas enters the chemical treatment liquid through a ventilation hole at one end of the ventilation pipe for a secondary reaction. However, the contact area between the gas and the chemical treatment liquid is limited by the simple opening method, resulting in insufficient reaction and difficulty in efficiently removing harmful gases.
[0005] To address this issue, we designed a deodorization device for livestock and poultry manure fermentation. Utility Model Content
[0006] The purpose of this invention is to provide a deodorizing device for fermenting livestock and poultry manure, so as to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides a deodorizing device for fermenting livestock and poultry manure, including a deodorizing box and a filter element installed at the air inlet of the deodorizing box. A purification liquid storage tank is connected to the top of the deodorizing box, and a first water pump is connected to one side of the purification liquid storage tank. A diversion pipe is connected inside the deodorizing box for spraying a mist of purification liquid. The inlet and outlet of the first water pump are respectively connected to the purification liquid storage tank and the diversion pipe.
[0008] Furthermore, a recycling box is connected to the bottom of the deodorizing box, and a stirring rack is rotatably connected inside the recycling box. The top of the recycling box is connected to a plurality of collection holes arranged in a rectangular array, one end of which vertically penetrates the bottom of the deodorizing box. A dual-shaft motor for driving the stirring rack to rotate is connected to one side of the recycling box. A second water pump is connected to the top of the deodorizing box, and the inlet and outlet of the second water pump are respectively connected to the recycling box and the purification liquid storage box.
[0009] Furthermore, multiple guide plates are rotatably connected inside the deodorization box. The guide plates are close to the air intake side of the deodorization box. One end of the guide plate is connected to a transmission gear, and a driven rack is meshed on the transmission gear. A drive mechanism that drives the driven rack to reciprocate is connected to one side of the deodorization box.
[0010] Furthermore, the drive mechanism includes,
[0011] An abutment roller is positioned below the deodorizing box. One end of the driven rack extends to the outside of the deodorizing box and is connected to a fixing frame. The abutment roller is rotatably connected within the fixing frame. A rotatable abutment cam is provided at the bottom of the abutment roller.
[0012] When the abutting cam rotates, it can drive the abutting roller to move vertically.
[0013] Furthermore, the other drive end of the dual-axis motor is connected to a first synchronous pulley, and a second synchronous pulley is coaxially arranged on one side of the abutting cam. A synchronous belt drives the first and second synchronous pulleys together.
[0014] Furthermore, the bottom of the deodorizing box is connected to a mounting plate, and a guide rod is connected to one side of the driven rack. The guide rod is slidably connected to the mounting plate, and the mounting plate is provided with a sliding groove that matches the guide rod.
[0015] Furthermore, a return spring is connected to the top of the driven rack, and the other end of the return spring is connected to the inner top wall of the deodorizing box.
[0016] Furthermore, an air inlet pipe and an air outlet pipe are respectively connected to both sides of the deodorization box.
[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: Firstly, preliminary filtration through the filter element reduces impurities in the gas. Secondly, the first water pump and the diversion pipe spray the purified liquid into a mist, increasing the contact area with harmful gases and improving purification efficiency. Furthermore, the purified liquid circulation structure, consisting of a recovery tank, a stirring rack, a dual-shaft motor, and a second water pump, not only achieves the recycling of the purified liquid and reduces operating costs, but also ensures sufficient contact between the purified liquid and the purifying agent through stirring, thus purifying the liquid and continuously and stably purifying harmful gases.
[0018] Compared with existing technologies, the beneficial effects of this invention are as follows: Before use, the guide plate rotates under the drive mechanism, which effectively changes the flow path of the gas produced by the fermentation of livestock and poultry manure. This design disrupts the gas flow direction, preventing the gas from passing directly through the deodorization box, increasing the residence time of the gas in the box, and allowing it to fully react with the filter elements.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 This utility model provides a technical solution: a deodorizing device for fermenting livestock and poultry manure, including a deodorizing box 1 and a filter element 2 installed at the air inlet of the deodorizing box 1. A purification liquid storage tank 3 is connected to the top of the deodorizing box 1. A first water pump 4 is connected to one side of the purification liquid storage tank 3. A diversion pipe 5 is connected inside the deodorizing box 1 for spraying a mist of purification liquid. The inlet and outlet of the first water pump 4 are respectively connected to the purification liquid storage tank 3 and the diversion pipe 5.
[0026] It should be noted that filter element 2 includes a variety of common purification components such as activated carbon filter, dust removal plate and silica gel drying plate. This is existing technology, so it will not be explained in detail here.
[0027] In practice, the gas produced by the fermentation of livestock and poultry manure enters through the filter element 2 at the air inlet of the deodorizing box 1. The purification liquid in the purification liquid storage tank 3 is transported to the distribution pipe 5 by the first water pump 4, and the distribution pipe 5 sprays the purification liquid into a mist. The gas containing harmful gases comes into full contact with the mist of purification liquid inside the deodorizing box 1, reacting to remove the harmful gases. This setup increases the contact area between the purification liquid and the gas by spraying the mist of purification liquid.
[0028] See Figure 1-4 The bottom of the deodorizing box 1 is connected to a recycling box 6. Inside the recycling box 6, a stirring rack 7 is rotatably connected. The top of the recycling box 6 is connected to multiple collection holes arranged in a rectangular array. One end of each collection hole vertically penetrates the bottom of the deodorizing box 1. A dual-shaft motor 9 that drives the stirring rack 7 to rotate is connected to one side of the recycling box 6. The top of the deodorizing box 1 is connected to a second water pump 8. The inlet and outlet of the second water pump 8 are respectively connected to the recycling box 6 and the purification liquid storage box 3.
[0029] It should be noted that an inlet pipe can be connected to one side of the recycling tank 6 for conveying the purified liquid.
[0030] In practice, the liquid reacting with the purification solution in the deodorization tank 1 flows into the recovery tank 6 through the collection hole at the bottom of the deodorization tank 1. A dual-shaft motor 9 drives the stirring frame 7 to rotate, stirring the liquid in the recovery tank 6. A second water pump 8 draws the liquid from the recovery tank 6 back to the purification solution storage tank 3, achieving the recycling of the purification solution. This setup enables the recycling of the purification solution, reduces waste, and lowers operating costs.
[0031] See Figure 1-4 Multiple guide plates 10 are rotatably connected inside the deodorizing box 1. The guide plates 10 are close to the air intake side of the deodorizing box 1. One end of the guide plate 10 is connected to a transmission gear 11. A driven rack 12 is meshed on the transmission gear 11. A drive mechanism that drives the driven rack 12 to move back and forth is connected to one side of the deodorizing box 1.
[0032] In practice, the drive mechanism drives the driven rack 12 to reciprocate, and the driven rack 12 meshes with the transmission gear 11, thereby causing the transmission gear 11 to drive the guide plate 10 to rotate. After the gas containing harmful gases enters the deodorization box 1, the rotation of the guide plate 10 changes the flow path of the gas, allowing the gas to fully contact the filter element 2.
[0033] See Figure 1-4 The drive mechanism includes,
[0034] An abutment roller 13, positioned below the deodorizing box 1, extends from one end of the driven rack 12 to the outside of the deodorizing box 1 and is connected to a fixing frame. The abutment roller 13 is rotatably connected within the fixing frame. A rotatable abutment cam 14 is provided at the bottom of the abutment roller 13.
[0035] When the abutting cam 14 rotates, it can drive the abutting roller 13 to move vertically.
[0036] In practice, when the abutting cam 14 rotates, its eccentric structure causes the abutting roller 13 to move vertically. The abutting roller 13 is connected to the driven rack 12, which in turn drives the driven rack 12 to move up and down reciprocally, thereby driving the guide plate 10.
[0037] See Figure 1-4 The other drive end of the dual-axis motor 9 is connected to a first synchronous pulley 15, and a second synchronous pulley 16 is coaxially arranged on one side of the cam 14. A synchronous belt 17 is connected between the first synchronous pulley 15 and the second synchronous pulley 16.
[0038] In practice, one drive end of the dual-axis motor 9 drives the first synchronous pulley 15 to rotate, and the first synchronous pulley 15 drives the second synchronous pulley 16 to rotate through the synchronous belt 17. The second synchronous pulley 16 is coaxially arranged with the abutting cam 14, thereby causing the abutting cam 14 to rotate and realizing the transmission of power.
[0039] See Figure 1-4 The bottom of the deodorizing box 1 is connected to a mounting plate 18, and a guide rod is connected to one side of the driven rack 12. The guide rod is slidably connected to the mounting plate 18, and the mounting plate 18 is provided with a sliding groove that matches the guide rod.
[0040] In practice, during the movement of the driven rack 12, the guide rod connected to one side slides in the groove of the mounting plate 18, which guides and stabilizes the driven rack 12, ensuring that the driven rack 12 moves back and forth smoothly.
[0041] See Figure 1-4 A return spring is connected to the top of the driven rack 12, and the other end of the return spring is connected to the inner top wall of the deodorizing box 1.
[0042] In practice, when the drive mechanism drives the driven rack 12 to move downward, the return spring will pull the driven rack 12 upward when the drive mechanism stops working, so that it returns to its initial position and prepares for the next reciprocating motion.
[0043] See Figure 1-4 The deodorizing box 1 has an air inlet pipe and an air outlet pipe connected to its two sides respectively.
[0044] In practice, the air inlet pipe is used to introduce the gas containing harmful gases produced by the fermentation of livestock and poultry manure into the deodorization box 1 for purification, while the air outlet pipe discharges the purified gas from the deodorization box 1 to achieve gas circulation.
[0045] Working Principle: Before use, the gas produced by the fermentation of livestock and poultry manure is first diverted by the guide plate 10, which is rotatably connected inside the deodorization box 1, under the action of the drive mechanism. The rotating abutment cam 14 in the drive mechanism drives the abutment roller 13 to move vertically, which in turn drives the driven rack 12 to move back and forth. The driven rack 12 meshes with the transmission gear 11, causing the transmission gear 11 to drive the guide plate 10 to rotate. The rotation of the guide plate 10 changes the flow path of the gas, disrupts the gas flow direction, and performs preliminary filtration through the filter element 2 at the air inlet of the deodorization box 1, removing some impurities. The purification liquid in the purification liquid storage tank 3 is transported to the diversion pipe 5 under the action of the first water pump 4. The diversion pipe 5 sprays the purification liquid into a mist, filling the interior of the deodorization box 1. At this time, the gas containing harmful gases such as hydrogen sulfide, methane, and skatole comes into full contact with the mist purification liquid inside the deodorization box 1.
[0046] The purified liquid, after reacting with the harmful gases, flows into the recovery tank 6 through the collection hole connected to the bottom of the deodorization tank 1. Inside the recovery tank 6, the stirring rack 7 rotates under the drive of the dual-shaft motor 9, stirring and purifying the recovered purified liquid. Subsequently, the second water pump 8 pumps the liquid from the recovery tank 6 back to the purification solution storage tank 3, achieving the recycling of the purified liquid and continuously purifying subsequent harmful gases.
