Description

Technical Field

[0001] The present invention relates to the technical field of feces recovery, and in particular to a feces recovery and treatment device for breeding houses. Background Art

[0002] In poultry houses, poultry produce a large amount of excrement every day. Since the excrement of poultry is rich in nutrients such as nitrogen, phosphorus, and potassium, these excrement are usually recycled and converted into organic fertilizer to recycle resources and reduce environmental burden. Among them, since the existing poultry excrement contains a lot of water, the water in the poultry excrement accelerates the loss of nutrients in the excrement, reduces the quality of the fertilizer, and the excrement containing water is very easy to breed pathogens and produce ammonia, hydrogen sulfide and other malodorous gases, which have adverse effects on the surrounding environment. Therefore, dehydration treatment is a key link in the excrement recycling process. Although currently Filter dehydration or two layers of filter cloth wrapped poultry manure for squeezing dehydration are often used, but both methods have obvious defects. During the centrifugal dehydration process, the filter holes of the filter are blocked by centrifugal impurities in the feces, affecting the continuous discharge of water in the feces, resulting in low continuous dehydration efficiency of the feces. In the process of squeezing two layers of filter cloth to dehydrate the feces between them, part of the water in the feces close to the upper filter cloth is retained on the upper filter cloth after infiltration. Subsequently, under the adsorption of feces and the gravity of water, the water is very easy to mix with the feces again, resulting in poor dehydration effect, thereby affecting the overall treatment effect.

[0039] In order to more clearly illustrate the technical solution of the embodiment of the present invention, the drawings of the embodiment will be briefly introduced below. Obviously, the drawings in the following description only involve some embodiments of the present invention, rather than limiting the present invention. The first power member 111 and the second power member 4 are both configured as drive motors.

[0040] Research has found that in the process of dehydrating the water in feces using a filter, fecal impurities adhere to and clog the mesh of the filter, affecting the continuous dehydration efficiency of the filter, that is, affecting the recovery efficiency of dry feces. In the process of dehydrating the wrapped feces using two layers of filter cloth, a large amount of water in the feces seeps out from the upper filter cloth and remains on it. The subsequent residual water can easily re-enter the feces, resulting in incomplete dehydration of the feces.

[0041] In view of this phenomenon, the present invention designs a feces recovery and processing device which can continuously dehydrate feces.

[0042] Example 1: A feces recovery and treatment device for a breeding house, referring to Figure 1-Figure 3As shown, it includes a support frame 1, a control panel is installed on the front side of the support frame 1, nine rotating shafts 11 are rotatably arranged on the support frame 1, the nine rotating shafts 11 are divided into two groups, and the two rotating shafts 11 in the middle are shared by the two groups, two first power members 111 are fixedly connected to the front side of the support frame 1, the two first power members 111 are electrically connected to the control panel, the output shafts of the first power members 111 are fixedly connected to the adjacent rotating shafts 11, and the adjacent rotating shafts 11 are driven by pulleys and belts to drive all the rotating shafts 11 to rotate accordingly, filter cloths 12 are wound around the two groups of rotating shafts 11, and the filter cloths 12 are in a taut state, wherein the rotating shaft 11 on the upper left side and the rotating shaft 11 on the lower left side are connected to the filter cloth 12. The moving shafts 11 are each provided with an air jet chamber, and the two rotating shafts 11 are both connected to the air pump. When the air pump is working, the two rotating shafts 11 eject gas to recoil the two filter cloths 12. Four groups of first rotating rollers 13 with rectangular distribution are arranged in the middle of the support frame 1. The four groups of first rotating rollers 13 are located between the two common rotating shafts 11. Each group of first rotating rollers 13 includes two symmetrical ones in the upper and lower parts. The overlapping parts of the two filter cloths 12 pass through the four groups of first rotating rollers 13 in sequence, and the overlapping parts of the two filter cloths 12 are distributed in a serpentine shape. Two groups of slide grooves are arranged on the support frame 1. Each group of slide grooves on the support frame 1 includes two symmetrical ones in the front and back. Second rotating rollers 14 are slidably arranged in the two groups of slide grooves of the support frame 1. The second rotating roller 14 is located between two adjacent groups of first rotating rollers 13, and the second rotating roller 14 is squeezed and matched with the adjacent filter cloth 12. Four liquid guide shells 15 are fixedly connected in the support frame 1, and the four liquid guide shells 15 are used to collect and guide the filtrate filtered on the two filter cloths 12. The upper part of the support frame 1 is fixedly connected to a storage shell 16 through a connecting rod, and the lower side of the storage shell 16 is fixedly connected and connected to a material guide shell 17, and the material guide shell 17 is located above the upper filter cloth 12. The right part of the support frame 1 is fixedly connected to a first baffle 18, and the first baffle 18 is located on the right side of the upper filter cloth 12. The left part of the support frame 1 is fixedly connected to a discharge shell 19, and the discharge shell 19 is located below the separation portion of the two filter cloths 12. Two diverter frames 191 are fixedly connected to the upper part of the frame 1, and the gaps on the two diverter frames 191 are staggered. The diverter frames 191 are in contact with the filter cloth 12 on the upper side. The diverter frames 191 are used to divert feces so that the moisture in the feces can be better discharged. The support frame 1 is provided with a pressure adjustment mechanism for controlling the movement of the two second rotating rollers 14, and the support frame 1 is provided with a limiting mechanism for adjusting the amount of material on the two filter cloths 12. The serpentine distribution of the overlapping parts of the two filter cloths 12 is utilized to make the upper and lower filter cloths 12 successively located below the feces between the two filter cloths 12, so that the moisture in the feces between the two filter cloths 12 can be quickly discharged through the two filter cloths, thereby improving the discharge efficiency of the moisture in the feces.

[0043] refer to Figure 1 and Figure 4As shown, the pressure regulating mechanism includes two evenly distributed fixed blocks 2, both of which are fixedly connected to the front side of the support frame 1, a first threaded rod 21 is threadedly provided on the middle part of the fixed block 2, a connecting frame 22 is rotatably provided on the lower part of the first threaded rod 21, the connecting frame 22 is in contact and sliding cooperation with the support frame 1, the connecting frame 22 is slidably provided with a first sliding block 23 rotatably connected to the adjacent second rotating roller 14, a spring is installed between the first sliding block 23 and the adjacent connecting frame 22, and the first sliding block 23 is in contact and sliding cooperation with the support frame 1, there is damping between the first rotating roller 13 and the support frame 1, and the extrusion force of the two second rotating rollers 14 on the filter cloth 12 is changed by the rotation adjustment of the two first threaded rods 21, so that the moisture in the feces between the two filter cloths 12 is evenly discharged.

[0044] refer to Figure 3 , Figure 5 and Figure 6 As shown, the limiting mechanism includes a second baffle 3, which is fixed to the lower part of the support frame 1. The second baffle 3 is located at the starting end of the overlapping part of the two filter cloths 12. A fixed seat 31 is fixed to the upper part of the support frame 1. The fixed seat 31 is provided with a second sliding block 32. The second sliding block 32 is slidably provided with a first sliding frame 33 for shielding feces on the upper filter cloth 12. The first sliding frame 33 is located above the upper filter cloth 12. The front part of the first sliding frame 33 is rotatably provided with a second threaded rod 34 threadedly matched with the second sliding block 32. By rotating the second threaded rod 34, the gap between the first sliding frame 33 and the upper filter cloth 12 is adjusted, the thickness of the feces attached to the upper filter cloth 12 is controlled, and the pre-separation of water in the feces is accelerated.

[0045] The operator first starts the two first power members 111 through the control panel on the support frame 1, and then adds the feces impurities cleaned in the breeding house into the storage shell 16. Then the feces fall to the upper surface of the upper filter cloth 12 through the storage shell 16 and the guide shell 17. At this time, the two first power members 111 work to make the two filter cloths 12 move synchronously, and the rotation mode of the upper filter cloth 12 is approximately clockwise (with Figure 3 As an example), the filter cloth 12 on the lower side rotates approximately counterclockwise (with Figure 3For example, the rotation of the filter cloth 12 on the upper side drives the feces discharged by the material guide shell 17 to move to the right. During this process, part of the water in the feces passes through the filter cloth 12 on the upper side and falls into the liquid guide shell 15 on the upper side. Then, the filtered waste liquid is discharged through the liquid guide shell 15. When the upper filter cloth 12 drives the feces thereon to pass through the two diverter racks 191, the diverter rack 191 divides and scrapes the feces on the filter cloth 12, so that the water on the upper surface of the feces flows through the upper filter cloth 12 to the liquid guide shell 15 on the upper side, and the water in the feces is initially filtered. At the same time, when the upper filter cloth 12 drives the feces to pass through the first sliding rack 33, the first sliding rack 33 scrapes and limits the thickness of the feces on the filter cloth 12 to control the thickness of the feces on the filter cloth 12, thereby further improving the separation of water in the feces, and the subsequent feces falls on the filter cloth 12 on the lower side.

[0046] After the feces fall onto the filter cloth 12 on the lower side, the moisture in the feces falls onto the liquid guide shell 15 on the lower side through the filter cloth 12 on the lower side, and then the filter cloth 12 on the lower side rotates to drive the feces falling thereon to move to the left, wherein the second baffle plate 3 limits and blocks the feces moving to the left, controls the feces thickness on the filter cloth 12 on the lower side, and then the feces on the lower filter cloth 12 moves to fit with the upper filter cloth 12, and then the two filter cloths 12 clamp the feces of the specified thickness and move in a serpentine manner. During the serpentine movement, under the elastic action of the springs connected to the two connecting frames 22, the two second rotating rollers 14 press the two overlapping filter cloths 12, so that the two filter cloths 12 are pressed against each other. The moisture in the feces clamped between the filter cloths 12 is discharged, wherein the elastic force of the springs connecting the lower connecting frame 22 is smaller than that of the springs connecting the upper connecting frame 22, that is, the squeezing force of the lower second rotating roller 14 on the adjacent filter cloths 12 is smaller than that of the upper second rotating roller 14 on the adjacent filter cloths 12, so that the moisture in the feces gradually passes through the adjacent filter cloths 12 and falls on the adjacent liquid guide shells 15, thereby preventing fecal impurities from penetrating into the filter cloths 12 and clogging the filter holes thereon due to excessive squeezing force. At the same time, the serpentine distribution of the two overlapping filter cloths 12 enables the moisture in the feces between the two to be discharged through the filter cloths 12 on both sides respectively, thereby accelerating the discharge of moisture in the feces.

[0047] When the feces follows the two filter cloths 12 to move to the vicinity of the discharge shell 19, the two filter cloths 12 move away from each other, and the dry feces impurities between the two parts fall on the discharge shell 19 and are discharged, completing the recovery of the dry feces, which is convenient for the subsequent processing of the feces into products such as fertilizers, and the four liquid guide shells 15 guide the separated filtrate to the next processing link.

[0048] When dehydrating feces of different consistencies, the operator adjusts the gap between the first sliding frame 33 and the upper filter cloth 12 by rotating the second threaded rod 34 to control the thickness of the feces on the upper filter cloth 12. Then, the operator adjusts the distance between the two connecting frames 22 and the adjacent first sliding blocks 23 by rotating the two first threaded rods 21, thereby changing the elastic force of the springs connected to the two connecting frames 22, that is, changing the squeezing force of the two second rotating rollers 14 on the filter cloth 12, thereby accelerating the discharge of water in the feces between the two filter cloths 12.

[0049] After all the feces are completely dehydrated, the operator turns off the two first power members 111 through the control panel. If the device is not used again, the operator cleans the device with clean water. If the feces are to be dehydrated again, the above operation can be repeated.

The four partition plates 43 rotate to evenly discharge the feces entering the guide shell 17, thereby controlling the feces thickness of the upper filter cloth 12, making it easier for the moisture in the feces to be quickly discharged through the upper filter cloth 12.

[0054] When the upper filter cloth 12 drives the feces to move through the first sliding frame 33, the first sliding frame 33 intercepts the feces and controls the feces thickness of the upper filter cloth 12. Due to the different consistency of the feces, when the feces is too thick, the amount of feces accumulated on the left side of the first sliding frame 33 increases. At this time, the movement of the upper filter cloth 12 drives the movement of the feces to increase the squeezing force on the first sliding frame 33. The first sliding frame 33 and the second sliding block 32 will move to the right and compress the connected spring. The second sliding block 32 will move to the right and squeeze the telescopic end of the first telescopic rod 51 through the first rotating frame 5, so that the first telescopic rod 51 can move the liquid in the chamber. The body is pushed into the annular cavity of the fixed shell 54 and the second sliding frame 55 through the first conduit 53, and the liquid enters the fixed shell 54 so that the second sliding frame 55 drives the rotating wheel 44 to move backward together. The rotating wheel 44 moves backward so that the transmission ratio between it and the round cone wheel 41 becomes smaller. At this time, the second power member 4 works through the round cone wheel 41 and the rotating wheel 44 to drive the first rotating shaft 42 and the four partition plates 43 to rotate slower, control the amount of feces discharged from the guide shell 17 on the upper filter cloth 12, reduce the amount of feces accumulated on the left side of the first sliding frame 33, facilitate the water in the feces to quickly pass through the upper filter cloth 12, and improve the pretreatment efficiency of water in the feces.

[0055] After the feces falls onto the lower filter cloth 12 after pre-water separation, the gravity of the feces on the lower filter cloth 12 acts on the third sliding frame 61, and the third sliding frame 61 moves to stretch the tension spring connected thereto. At the same time, the third sliding frame 61 is pressurized to move the telescopic end of the second telescopic rod 62 downward. At this time, the liquid in the inner chamber of the second telescopic rod 62 is injected into the fixed shell 54 again through the second conduit 63 and the first conduit 53. The above operation is subsequently repeated to control the movement of the rotating wheel 44, and the transmission ratio between the frustum wheel 41 and the rotating wheel 44 is changed again to control the amount of feces on the lower filter cloth 12, and further control the amount of feces clamped between the two filter cloths 12, thereby improving the discharge efficiency of water in the feces, that is, improving the recovery efficiency of dry feces.

[0058] refer to Fig.10 and Fig.11 As shown, the self-cleaning component includes two ratchet frames 9 symmetrically arranged in upper and lower parts, and the two ratchet frames 9 are slidably arranged at the front part of the support frame 1, and two springs symmetrically arranged in upper and lower parts are installed between the two ratchet frames 9 and the support frame 1, and the front end of the second rotating frame 72 is fixedly connected with a ratchet wheel 91 which contacts and cooperates with the adjacent ratchet frame 9, and the lower part of the fourth sliding frame 71 is rotatably arranged with a swing plate 92 which contacts and cooperates with the adjacent scraper 73, and a torsion spring is installed between the swing plate 92 and the adjacent fourth sliding frame 71, and the scraper 73 which contacts with the filter cloth 12 is switched by utilizing the limiting cooperation of the ratchet wheel 91 and the adjacent ratchet frame 9, so as to improve the cleaning effect of the fecal impurities attached to the filter cloth 12, thereby prolonging the continuous filtering time of the feces by the filter cloth 12.

[0059] During the above-mentioned feces dehydration process, as the two filter cloths 12 move away from each other, the dehydrated feces between the two filter cloths 12 are discharged through the discharge shell 19. At this time, under the action of the elastic force of the spring connected to the scraper 73, the scraper 73 on the right side of the second rotating frame 72 is tightly attached to the adjacent filter cloth 12. At this time, the two rightmost scrapers 73 scrape the left sides of the two filter cloths 12 to reduce the amount of feces impurities attached to the two filter cloths 12.

[0060] During the process of the rotating shaft 11 driving the two filter cloths 12 to move, the two rotating shafts 11 on the left rotate through the two first pulleys 81 and the adjacent belts to drive the two second pulleys 82 to rotate, the second pulleys 82 rotate through the connected torsion springs to drive the adjacent turntable 83 and the adjacent second rotating shaft 8 to rotate, the second rotating shaft 8 rotates through the bevel gear set to drive the adjacent third rotating shaft 85 and the adjacent spline sleeve 86 to rotate, at this time, due to the limiting effect of the convex column on the support plate 7 on the spiral groove on the spline sleeve 86, the spline sleeve 86 moves along the adjacent support plate 7.

[0061] The spline sleeve 86 moves to compress the connected spring, and the spline sleeve 86 simultaneously drives the adjacent fourth sliding frame 71 and the adjacent second rotating frame 72 to move through the adjacent third fixed frame 87. The second rotating frame 72 moves so that the scraper 73 on the right side thereof scrapes impurities off the adjacent filter cloth 12. During the movement of the fourth sliding frame 71 and the adjacent second rotating frame 72, due to the limiting effect of the one-way bearing on the second rotating frame 72, the second rotating frame 72 drives the adjacent ratchet 91 to move, and the second rotating frame 72 and the adjacent ratchet 91 remain stationary. At this time, the ratchet 91 squeezes the adjacent ratchet frame 9 to move back and forth, and due to the elastic force of the spring connected to the ratchet frame 9, the ratchet frame 9 is always close to the adjacent ratchet 91.

[0062] After the boss on the support plate 7 moves to the vertical groove on the spline sleeve 86, the rotating shaft 11 on the left side continues to rotate and drives the second pulley 82 to rotate through the connected parts. Under the limiting effect of the vertical groove on the spline sleeve 86, the spline sleeve 86, the third rotating shaft 85 and the second rotating shaft 8 stop rotating. At this time, the second pulley 82 rotates and twists the connected torsion spring. At the same time, under the elastic force of the spring on the spline sleeve 86, the spline sleeve 86 drives the adjacent third fixed frame 87 and the adjacent fourth sliding frame 71 to move in the opposite direction and reset. The fourth sliding frame 71 moves and drives the connected The connected parts move in the opposite direction to reset. At this time, due to the limiting effect of the ratchet frame 9 on the adjacent ratchet wheel 91, the ratchet wheel 91 drives the adjacent second rotating frame 72 to rotate. The second rotating frame 72 rotates so that another scraper 73 on it faces the adjacent filter cloth 12. The second rotating frame 72 rotates so that the corresponding scraper 73 passes through the swing plate 92. The swing plate 92 cleans the scraper 73. The fecal impurities scraped off by the scraper 73 on the lower side are located in the lower left area of ​​the support frame 1. Subsequent operators only need to regularly clean the fecal impurities near the support frame 1.

[0063] During the continuous rotation of the rotating shaft 11, the four scrapers 73 on the two second rotating frames 72 scrape the adjacent filter cloths 12 alternately and reciprocally, reducing the adhesion of fecal impurities on the filter cloths 12, making it easier for the filter cloths 12 to continuously and stably dehydrate the feces, thereby improving the recovery efficiency of dry feces.
