Description

Technical Field

[0001] This invention relates to the field of manure dehydration technology, specifically a broiler chicken farming waste treatment device. Background Technology

[0002] With the rapid development of large-scale broiler farming, the large amount of manure generated during the farming process has become an urgent environmental problem to be solved. Chicken manure mainly consists of undigested feed residue, minerals such as nitrogen, phosphorus, and potassium, microorganisms, and a small amount of impurities. After dehydration and harmless treatment, it can be made into various products such as organic fertilizer, feed raw materials, and biomass fuel. Therefore, manure dewatering machines are widely used as a common manure dewatering equipment. The core principle of the spiral manure dewatering machine is solid-liquid separation through spiral shaft extrusion and screen filtration. It squeezes out the water from the manure through mechanical force to achieve dry and wet separation. This technology is disclosed and recorded in CN110467329B, a spiral extrusion manure dewatering machine, and CN208038332U, a poultry and livestock manure dewatering machine.

[0003] However, in actual farming, most of the manure produced is discharged into manure pits via water flushing. The manure in these pits is in a fluid or semi-fluid state with a high water content. Directly using a spiral manure dewatering machine would result in low dewatering efficiency and significant dewatering difficulty. Therefore, an overflow-type manure dewatering machine has been developed. This machine consists of three parts: an overflow chamber, an inclined screen, and a dewatering chamber. The manure entering the overflow chamber is poured onto the inclined screen for initial dewatering, and a vibrating motor further dewaters the manure. After being washed, the feces fall into the dewatering chamber, where they are finally dehydrated, such as in the CN206762400U high-efficiency feces dewatering machine. This method of feces dewatering improves dewatering efficiency. During the process of the feces water falling along the inclined screen, although most of the sewage in the newly fallen feces water will pass through the inclined screen for dewatering, some sewage in the feces water will still be transferred along the inclined surface to the feces that were originally on the inclined screen, affecting the coarse dewatering effect of the feces water on the inclined screen. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a broiler farming waste treatment device. In this invention, the manure water on the screen surface is separated into multiple independent cavities by multiple partitions, so that the manure water at the upper part of the screen surface will not transfer sewage to the manure at the lower part of the screen surface, thereby enabling the manure water on the screen surface to be dehydrated independently, thus improving the dehydration effect of the manure water.

[0012] Preferably, the side of the lever away from the corresponding partition is provided with a vertical block; the lever bar is rod-shaped and rotatably connected to the vertical block.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 9 As shown, the present invention includes the following embodiments: Example 1: A broiler waste treatment device includes an inclined box 1; a U-shaped sieve plate 2 with sieve holes 21 is fixedly connected to the inclined opening of the inclined box 1; an overflow chamber 3 is provided at the top of the inclined box 1, communicating with the upper end of the U-shaped sieve plate 2; a dehydration chamber 4 is provided at the bottom of the inclined box 1, communicating with the lower end of the U-shaped sieve plate 2; a collection tank 11 is provided inside the inclined box 1 for collecting liquid dripping from the sieve holes 21; a drain pipe 12 is provided rearwardly connected to the collection tank 11; the overflow chamber... 3. The solid and liquid waste enters the dewatering chamber 4 after moving along the U-shaped screen plate 2; the upper and lower positions of the inner side of the U-shaped screen plate 2 are rotatably connected to the rollers 5; the outer walls of the two rollers 5 are connected to the transmission belt 6; the outer wall of the transmission belt 6 is uniformly fixedly connected to the partition 7 along the transmission direction; the partition 7 is in contact with the screen surface 22 and inner side 23 of the U-shaped screen plate 2 after being driven by the transmission belt 6; the vibrating motor 25 is fixedly connected to the U-shaped screen plate 2 by the bracket 24.

[0025] After the treatment device is connected to the corresponding pipeline, a sludge pump or a non-clogging pump is used to pump sewage from the septic tank into the overflow chamber 3. As the amount of sewage in the overflow chamber 3 increases, the sewage will overflow from the upper port of the overflow chamber 3. The upper port of the overflow chamber 3 faces the inclined direction of the U-shaped screen plate 2, that is, the sewage discharge direction of the overflow chamber 3 is consistent with the inclined direction of the U-shaped screen plate 2. After the sewage enters the inner bottom wall of the U-shaped screen plate 2, it will contact the corresponding partition 7. The vibration motor 25 will transmit the vibration force to the U-shaped screen plate 2 through the bracket 24. Under the action of its own gravity and vibration force, the sewage moves downward along the inclined surface of the U-shaped screen plate 2. During the movement of the sewage, it will push the corresponding partition 7 to move. The partition 7 connected to the inner half of the transmission belt 6 moves in an inclined downward direction, the partition 7 around the lower roller 5 moves in an upward flipping direction, and the partition 7 connected to the outer half of the transmission belt 6 moves in an inclined direction. The partitions 7 around the upper roller 5 rotate downwards. After rotating, the partitions 7 around the upper roller 5 come into contact with the screen surface 22 of the U-shaped screen plate 2. This causes the partitions 7 connected to the inner half of the transmission belt 6 to separate the sewage. Two adjacent partitions 7 form a cavity. As the sewage in the cavity moves downwards along the screen surface 22 of the U-shaped screen plate 2, the sewage in the sewage passes through the screen holes 21 on the screen surface 22 of the U-shaped screen plate 2 and finally drips into the collection tank 11 for collection. The wet sewage on the screen surface 22 continues to move downwards along the screen surface 22. Because the sewage on the screen surface 22 is separated into multiple independent cavities by multiple partitions 7, the sewage on the upper part of the screen surface 22 will not transfer sewage to the sewage on the lower part of the screen surface 22. This allows the sewage on the screen surface 22 to be dehydrated independently, thus improving the dehydration effect of the sewage.

[0026] As the partition 7 around the lower roller 5 flips upwards, the lower end of the U-shaped screen plate 2 exposes the feces. The feed inlet of the dewatering chamber 4 is aligned with the lower end of the U-shaped screen plate 2, so the wet feces will detach from the partition 7 and the U-shaped screen plate 2 and enter the dewatering chamber 4. The dewatering chamber 4 uses the squeezing principle (this is existing technology) to squeeze the wet feces. The sewage generated during the squeezing process is guided by the branch pipe and collected in the collection tank 11. The sewage in the collection tank 11 will be discharged along the drain pipe 12 at the rear. The discharge port of the dewatering chamber 4 will break up and discharge the dewatered feces.

[0027] In this embodiment, since the fecal water on the U-shaped screen plate 2 moves downward along its respective independent cavities and pushes the corresponding cavities 7, and multiple cavities 7 are connected to the same transmission belt 6, the force on all cavities 7 can be transmitted to each other. Thus, the fecal water moving up and down on the U-shaped screen plate 2 can be transmitted to other cavities 7 through the corresponding cavities 7 and the transmission belt 6, so that other cavities 7 can push the fecal water that is difficult to move downward in the cavities to continue to move downward, so that the wet fecal water on the U-shaped screen plate 2 can fall smoothly, ensuring the smooth dehydration of the fecal water, and also avoiding the problem of fecal residue on the U-shaped screen plate 2 affecting the subsequent dehydration of the fecal water.

[0028] Example 2: The U-shaped screen plate 2 has a rotating hole 26 through it on its side; the end of the rotating roller 5 is rotatably connected to the rotating hole 26; the wall of the rotating hole 26 has a threaded hole 27 through it facing outward; a bolt 8 is threadedly connected to the threaded hole 27; the end of the bolt 8 is connected to the pressure block 82 through a first spring 81.

[0029] In this embodiment, the outer wall of the rotating roller 5 is provided with teeth 51 along the circumferential direction; the inner wall of the transmission belt 6 is provided with grooves 61 along the transmission direction; the teeth 51 can be sequentially engaged with the corresponding grooves 61 during the transmission process of the transmission belt 6.

[0030] The sewage flowing out of the overflow chamber 3 will undergo preliminary dewatering through the screen surface 22 of the U-shaped screen plate 2. For sewage with a high water content, the residence time of the sewage on the U-shaped screen plate 2 will be appropriately extended to improve the dewatering effect; for sewage with a low water content, the residence time of the sewage on the U-shaped screen plate 2 will be appropriately shortened to improve the dewatering efficiency. Specifically, the bolt 8 is turned in the threaded hole 27. When the bolt 8 is turned in the forward direction, it will approach the rotating hole 26. The bolt 8 will compress the first spring 81, and the first spring 81 will transmit the elastic force to the pressure block 82. The pressure block 82 will transmit the clamping force to the outer wall of the rotating roller 5, which will increase the resistance of the rotating roller 5 in the rotating hole 26. The transmission belt 6 drives the rotation on the outer wall of the rotating roller 5, so the transmission resistance of the transmission belt 6 increases, and the residence time of the sewage on the U-shaped screen plate 22 will be extended to improve the dewatering efficiency. The downward movement of the partition 7 on the inner half of the transmission belt 6 extends the dewatering time of the fecal water on the U-shaped screen plate 2. Tightening the bolt 8 in the opposite direction moves it away from the rotating hole 26, increasing the distance between the bolt 8 and the corresponding pressure block 82. This reduces the clamping force of the first spring 81 on the pressure block 82, and consequently reduces the clamping force of the pressure block 82 on the rotating roller 5. This reduces the transmission resistance of the transmission belt 6 and the rotating roller 5, shortens the downward movement time of the partition 7 on the inner half of the transmission belt 6, and improves the efficiency of fecal dewatering from the U-shaped screen plate 2. In this embodiment, by changing the rotational resistance of the rotating roller 5 in the rotating hole 26 by tightening the bolt 8, the transmission resistance of the transmission belt 6 is indirectly changed. As a result, the partition 7 can be adapted to the dewatering needs of fecal water with different moisture contents, making it widely applicable.

[0031] Example 3: An extension groove 71 is provided on the edge of the partition 7 away from the transmission belt 6; an extension strip 72 is slidably connected in the extension groove 71; the extension strip 72 is connected to the bottom of the extension groove 71 by an extension spring 73; the length of the partition 7 is adapted to the inner width of the U-shaped screen plate 2.

[0032] During the transmission process, the transmission belt 6 will drive all the partitions 7 on the outer wall to move. When the partitions 7 around the upper roller 5 are flipped downwards, the partitions 7 will drive the extension strips 72 to press against the screen surface 22 of the U-shaped screen plate 2. The extension strips 72 will be pressed to overcome the extension springs 73 and approach the bottom of the extension groove 71. This makes the partitions 7 and the screen surface 22 of the U-shaped screen plate 2 in elastic and sealed contact, thereby ensuring the partitions 7's effect on separating sewage and reducing the contact friction between the partitions 7 and the U-shaped screen plate 2. After the extension plate is separated from the screen surface 22 of the U-shaped screen plate 2, the extension springs 73 will push the extension plate away from the bottom of the extension groove 71.

[0033] Example 4: The two sides of the partition 7 are a manure-facing side and a manure-repelling side, respectively; the manure-facing side is provided with a sliding strip 74 and a lever 9 along the length of the partition 7; the sliding strip 74 is fixedly connected to the manure-facing side; the length of the lever 9 is less than the length of the partition 7; the side of the lever 9 facing the partition 7 is provided with a sliding groove 91; the sliding groove 91 is slidably connected to the sliding strip 74; the size of the sliding strip 74 is reduced as it approaches the corresponding partition 7; the side of the lever 9 away from the corresponding partition 7 is provided with a lever 92; lever rods 93 are fixedly connected to both ends of the lever 9; the U-shaped screen plate 2 is provided with annular track grooves 28 on both sides; the bottom of the annular track grooves 28 is corrugated; the corrugation directions of the bottoms of the two annular track grooves 28 are opposite.

[0034] In this embodiment, the depth of the half of the annular track groove 28 near the collection groove 11 is less than the depth of the half of the annular track groove 28 away from the collection groove 11; the corrugated bottom of the annular track groove 28 is set in the half near the collection groove 11.

[0035] In this embodiment, two adjacent dial plates 9 are arranged in opposite directions along the sliding bar 74.

[0036] During the transmission of the drive belt 6 along the upper and lower rollers 5, the drive belt 6 will drive all the partitions 7 to move along the transmission direction. During the movement of the partitions 7 along the transmission direction, the fixedly connected sliders 74 will move synchronously. The sliders 74 are slidably connected to the grooves 91 on the dial plate 9, so the sliders 74 will drive the dial plate 9 to move along the transmission direction. The size of the sliders 74 increases as it moves away from the corresponding partitions 7, so the sliders 74 will not detach from the grooves 91. During the movement of the dial plate 9 along the transmission direction, the dial rod 93 will move along the annular track groove 28. The half of the annular track groove 28 near the collection groove 11 is provided with a corrugated groove bottom, and the corrugated groove bottoms in the two annular track grooves 28 are arranged in opposite directions. Therefore, the peak of the corrugated groove bottom of one annular track groove 28 corresponds to the trough of the corrugated groove bottom of the other annular track groove 28. Thus, under the guidance of the two annular track grooves 28, the dial rod 93 will be driven to move back and forth along the length direction. During the back-and-forth movement of the lever 93, the lever 9 will move back and forth along the slide bar 74. The lever 9 will cause the slide bar 92 to oscillate back and forth in the width direction of the U-shaped screen plate 2. The back-and-forth movement of the slide bar 92 will spread the manure on the U-shaped screen plate 2 in the width direction, thus facilitating the dehydration of the manure. Furthermore, since the depth of the half of the annular track groove 28 away from the collection tank 11 is greater than the depth of the half of the annular track groove 28 near the collection tank 11, and the half of the annular track groove 28 away from the collection tank 11 is not provided with a corrugated groove bottom, the back-and-forth movement of the lever 93 will not be triggered when the lever 93 enters the half of the annular track groove 28 away from the collection tank 11, thus reducing the transmission loss of the entire transmission belt 6. Furthermore, the two adjacent levers 9 are arranged in opposite directions along the movement direction of the slide bar 74, which on the one hand avoids the concentrated movement of the levers 9 causing excessive instantaneous resistance of the transmission belt 6, making the transmission of the transmission belt 6 more stable, and on the other hand, makes the force on the transmission belt 6 more balanced and stable.

[0037] Example 5: The side of the dial plate 9 away from the corresponding partition plate 7 is provided with a vertical block 94; the dial bar 92 is rod-shaped and rotatably connected to the vertical block 94.

[0038] In this embodiment, the side of the lever 9 away from the corresponding partition 7 is provided with a plurality of vertical grooves 95 along the length direction of the lever 9; one end of the vertical groove 95 is close to the transmission belt 6, and the other end is away from the transmission belt 6; the vertical block 94 is slidably connected in the vertical groove 95; the end of the vertical groove 95 close to the transmission belt 6 is connected to the vertical block 94 by a vertical spring 96.

[0039] During the back-and-forth movement of the pusher plate 9 and the pusher bar 92, the rod-shaped pusher bar 92 comes into contact with the feces in the sewage. The rod-shaped pusher bar 92 can roll and press the feces in the sewage, so that the feces are spread out on the screen surface 22. The spread feces will expose the residual sewage, which will facilitate the dehydration of the feces. After being spread out, the feces will be scraped by the rear partition plate 7 and will be gathered again. This will cause the feces to be spread out back and forth, improving the dehydration effect of the feces. Furthermore, for feces with greater hardness, the rod-shaped pusher bar 92 can easily pass over them. The pusher bar 92 will drive the vertical block 94 to move along the vertical groove 95 against the vertical spring 96. The vertical spring 96 will transmit the elastic force to the pusher bar 92, ensuring the spreading force of the pusher bar 92 on the feces.

[0040] Example 6: The pressure block 82 is spherical; the rotating roller 5 is provided with a notch 52 on the arc-shaped outer wall of the rotating hole 26; the notch 52 is hemispherical; the pressure block 82 can enter or move out of the notch 52.

[0041] During the rotation of the roller 5, the roller 5 will generate sliding friction with the pressure block 82. A notch 52 is provided on the arc-shaped outer wall of the roller 5. The notch 52 is located inside the rotating hole 26. Therefore, the notch 52 will pass through the threaded hole 27. The pressure block 82 will transition from the outer wall of the roller 5 to the notch 52. The distance from the notch 52 to the center of the roller 5 is less than the distance from the arc-shaped outer wall of the roller 5 to the center of the roller 5. Therefore, the pressure of the pressure block 82 pressing on the notch 52 is less than the pressure of the pressure block 82 pressing on the arc-shaped outer wall of the roller 5. This makes the rotational resistance of the roller 5 change. This makes the transmission process of the transmission belt 6 variable. This makes the partition 7 drive the feces to move down at a variable speed. With the vibration of the vibrating motor 25, the feces approach the push plate 9 and are spread out by the push strip 92 on the push plate 9.

[0042] Example 7: A drainage pump (not shown in the figure) is installed in the drainage pipe 12. The drainage pump will continuously perform negative pressure adsorption on the collection tank 11, so that the collection tank 11 generates negative pressure, which improves the efficiency of sewage on the screen surface 22 passing through the screen hole 21.

[0043] Example 8: One of the rollers 5 is connected to the output shaft of an independent motor (not shown in the figure). The housing of the independent motor is fixedly connected to the U-shaped screen plate 2. The independent motor can assist or drive the roller 5 to rotate independently. The roller 5 can also be driven by the force of the sewage pushing the partition 7.
