Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment equipment, and in particular discloses a wastewater settling tank for slaughterhouses. Background Technology

[0002] The slaughtering and meat processing processes consume a large amount of water and discharge wastewater containing pollutants such as blood, grease, hair, meat scraps, livestock and poultry offal, undigested feed and feces. The wastewater mainly comes from pen washing, rinsing, slaughtering and other factory floor washing, scalding, dissection, side dish processing and oil washing.

[0003] Existing slaughterhouse wastewater treatment facilities typically include filtration tanks, sedimentation tanks, oil removal tanks, and disinfection tanks. Large debris is filtered out in the filtration tanks, small debris is settled in the sedimentation tanks, oil is removed from the wastewater in the oil removal tanks, and finally, the wastewater is disinfected in the disinfection tanks before being discharged.

[0004] In response to the aforementioned prior art, the inventors discovered that existing wastewater filtration and sedimentation methods require the simultaneous installation of filtration and sedimentation tanks, which takes up a large amount of space and is not suitable for large-scale treatment of slaughterhouse wastewater. Utility Model Content

[0005] In order to reduce the space occupied by slaughterhouse wastewater filtration and sedimentation, this application provides a slaughterhouse wastewater sedimentation tank.

[0006] This application provides a settling tank for slaughterhouse wastewater, which adopts the following technical solution:

[0007] A settling tank for slaughterhouse wastewater includes a settling tank body, an mounting plate, a filter plate, and a drive assembly. The mounting plate is detachably connected to the top of the settling tank body, and an inlet is provided inside the mounting plate that is the same as the opening of the settling tank body. The filter plate is slidably connected inside the settling tank body, and the drive assembly is used to drive the filter plate to rise and fall, and the drive assembly is mounted on the mounting plate.

[0008] By adopting the above technical solution, after the slaughterhouse wastewater is discharged into the sedimentation tank, the filter plate is driven to rise by the drive component, which can filter large debris in the slaughterhouse wastewater. At the same time, the slaughterhouse wastewater discharged into the sedimentation tank can settle, reducing the space occupied by the filtration and sedimentation of slaughterhouse wastewater, which is conducive to the large-scale treatment of slaughterhouse wastewater.

[0009] Optionally, the drive assembly includes a first fixed plate, a winding roller, a first drive motor, and a rope. The first fixed plate is fixed on the mounting plate, the winding roller is rotatably connected to the first fixed plate, the first drive motor is fixed on the mounting plate, the output end of the first drive motor passes through the first fixed plate and is fixed to the winding roller, one end of the rope is fixed to the winding roller, and the other end of the rope is fixed to the filter plate.

[0010] By adopting the above technical solution, the first drive motor is started, which can drive the winding roller to rotate, so that the rope is retracted or extended, thereby raising and lowering the filter plate, which facilitates the filter plate to filter slaughterhouse wastewater.

[0011] Optionally, a cleaning assembly is also included, which is mounted on the mounting plate. The cleaning assembly includes a second fixed plate, a threaded rod, a second drive motor, a third fixed plate, a first guide rod, and a sweeping plate. The second fixed plate is fixed to the mounting plate, the threaded rod is rotatably connected to the second fixed plate, the second drive motor is fixed to the second fixed plate, and the output end of the second drive motor is fixed to the threaded rod. The third fixed plate is fixed to the mounting plate, the first guide rod is parallel to the threaded rod, and the first guide rod is fixed to the third fixed plate. One side of the sweeping plate is threaded to the threaded rod, and the other side of the sweeping plate is slidably connected to the first guide rod.

[0012] By adopting the above technical solution, when the filter cake plate rises to a level higher than the liquid level of the sedimentation tank body, the second drive motor is started. The second drive motor can drive the threaded rod to rotate, so that the cleaning plate moves on the filter cake plate, thereby cleaning large pieces of debris on the filter cake plate.

[0013] Optionally, the mounting plate is provided with a baffle whose bottom surface is flush with the upper surface of the mounting plate.

[0014] By adopting the above technical solution, the rising height of the filter cake plate is limited, so that the cleaning plate can just clean the filter cake plate.

[0015] Optionally, it also includes a detachable component, which includes a side protrusion and bolts. The side protrusion is fixed to the top of the outer side of the sedimentation tank body, and the mounting plate is detachably connected to the side protrusion by bolts.

[0016] By adopting the above technical solution, the mounting plate and the side convex plate are detachably connected by bolts. When there is a lot of sediment in the sedimentation tank body, the mounting plate can be removed so that the mounting plate will not block the staff from cleaning the sedimentation tank body.

[0017] Optionally, the detachable assembly further includes a second guide rod, wherein a guide hole is provided on the side convex plate, and the second guide rod is inserted into the guide hole.

[0018] By adopting the above technical solution, after the mounting plate is placed on the sedimentation tank body, the second guide rod is inserted into the guide hole, so that the mounting plate will not shift laterally, which facilitates the installation of bolts.

[0019] Optionally, the mounting plate is fixed with hooks.

[0020] By adopting the above technical solution, the mounting plate can be easily disassembled and lifted, thus facilitating its removal.

[0021] Optionally, the inner side of each of the four corners of the upper surface of the sedimentation tank body is provided with a sliding groove extending to the bottom surface of the sedimentation tank body, and a sliding plate is fixed at each of the four corners of the filter plate, the sliding plate being slidably connected in the sliding groove.

[0022] By adopting the above technical solution, it is possible to prevent the filter plate from tipping over when it rises, thus facilitating the stable lifting and lowering of the filter plate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. After the slaughterhouse wastewater is discharged into the settling tank, the filter plate is driven to rise by the drive component, which can filter large debris in the slaughterhouse wastewater. At the same time, the settling tank can settle the slaughterhouse wastewater discharged into the settling tank, reducing the space occupied by the filtration and settling of slaughterhouse wastewater, which is conducive to the large-scale treatment of slaughterhouse wastewater.

[0025] 2. Start the first drive motor. The first drive motor can drive the winding roller to rotate, so that the rope is retracted or extended, thereby raising and lowering the filter plate, which facilitates the filter plate to filter slaughterhouse wastewater.

[0026] 3. When the filter cake plate rises to a level higher than the liquid level of the sedimentation tank body, the second drive motor is started. The second drive motor can drive the threaded rod to rotate, so that the cleaning plate moves on the filter cake plate, thereby cleaning the large pieces of debris on the filter cake plate.

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses a wastewater settling tank for slaughterhouses. (Refer to...) Figure 1 A slaughterhouse wastewater settling tank includes a settling tank body 1, a mounting plate 2, a filter plate 3, a drive assembly 4, a cleaning assembly 5, and a detachable assembly 7. The mounting plate 2 is detachably connected to the settling tank body 1 via the detachable assembly 7. The filter plate 3 is slidably connected within the settling tank body 1. The drive assembly 4 is used to drive the filter plate 3 to rise and fall. The cleaning assembly 5 is used to clean the filter plate 3.

[0032] Reference Figure 1 The sedimentation tank body 1 has grooves 11 extending to the inner bottom surface of the sedimentation tank body 1 at the four inner corners of its upper surface. A mounting plate 2 covers the upper surface of the sedimentation tank body 1, and a water inlet with the same opening as the sedimentation tank body 1 is located in the middle of the mounting plate 2. The detachable component 7 includes side protrusions 71, bolts 72, and second guide rods 73. Two side protrusions 71 are provided, symmetrically fixed to the outer side of the sedimentation tank body 1. The upper surface of the side protrusions 71 is flush with the upper surface of the sedimentation tank body 1. Each side protrusion 71 has two symmetrically distributed guide holes on its upper surface. Two bolts 72 are provided. The mounting plate 2 and the side protrusions 71 are detachably connected by bolts 72. Four second guide rods 73 are provided, symmetrically fixed to the bottom surface of the mounting plate 2. The bottom edge of the second guide rods 73 has a chamfered edge. After the mounting plate 2 is placed over the sedimentation tank body 1, the second guide rod 73 is inserted into the guide hole to prevent the mounting plate 2 from shifting laterally, thus facilitating the installation of the bolts 72. Four symmetrically distributed hooks 8 are fixed on the upper surface of the mounting plate 2, which facilitates the lifting of the mounting plate 2 after disassembly, thereby making it easy to remove the mounting plate 2.

[0033] Reference Figure 1 and Figure 2 The drive assembly 4 consists of four sets, each installed at one of the four corners of the mounting plate 2. Each drive assembly 4 includes a first fixed plate 41, a winding roller 42, a first drive motor 43, and a rope 44. Two first fixed plates 41 are fixed to the upper surface of the mounting plate 2 at intervals. The winding roller 42 is rotatably connected between the two first fixed plates 41. The first drive motor 43 is fixed to the upper surface of the mounting plate 2, and its output end passes through the first fixed plate 41 and is fixed to the winding roller 42. One end of the rope 44 is fixed to the winding roller 42, and the other end is fixed to the slide plate 31 on the filter plate 3. When the first drive motor 43 is started, it drives the winding roller 42 to rotate, causing the rope 44 to retract or extend, thereby raising and lowering the filter plate 3 to facilitate the filtration of slaughterhouse wastewater.

[0034] Reference Figure 1The cleaning assembly 5 is mounted on the mounting plate 2. The cleaning assembly 5 includes a second fixing plate 51, a threaded rod 52, a second drive motor 53, a third fixing plate 54, a first guide rod 55, and a cleaning plate 56. Two second fixing plates 51 are symmetrically fixed on both sides of the mounting plate 2. The threaded rod 52 is rotatably connected between the two second fixing plates 51. The second drive motor 53 is fixed to the outer side of one of the second fixing plates 51, and its output end passes through the second fixing plate 51 and is fixed to the threaded rod 52. Two third fixing plates 54 are symmetrically fixed on the upper surface of the mounting plate 2. The first guide rod 55 is parallel to the threaded rod 52 and is fixed between the two third fixing plates 54. One side of the cleaning plate 56 is threadedly connected to the threaded rod 52, and the other side is slidably connected to the first guide rod 55. A baffle 6 with its bottom surface flush with the upper surface of the mounting plate 2 is fixed to the upper surface of the mounting plate 2. The rising height of the filter plate 3 is limited so that the cleaning plate 56 can just clean the filter plate 3.

[0035] Reference Figure 1 Once the filter plate 3 rises to the point where its upper surface is flush with the upper surface of the mounting plate 2, the baffle 6 restricts the filter plate 3 from rising further. When the filter plate 3 can no longer rise, the second drive motor 53 is activated. The second drive motor 53 drives the threaded rod 52 to rotate, causing the cleaning plate 56 to move on the filter plate 3, thereby cleaning large pieces of debris on the filter plate 3.

[0036] The implementation principle of a slaughterhouse wastewater settling tank according to an embodiment of this application is as follows: After the slaughterhouse wastewater is discharged into the settling tank body 1, the first drive motor 43 is started. The first drive motor 43 drives the winding roller 42 to rotate, causing the rope 44 to be wound into the winding roller 42, thereby causing the filter plate 3 to rise. The rising filter plate 3 can filter the slaughterhouse wastewater. When the filter plate 3 rises to the point that its upper surface is flush with the upper surface of the mounting plate 2, the baffle 6 restricts the filter plate 3 from rising further. The second drive motor 53 can drive the threaded rod 52 to rotate, causing the cleaning plate 56 to move on the filter plate 3, thereby cleaning large pieces of debris on the filter plate 3. The settling tank body 1 can settle the slaughterhouse wastewater discharged into it, reducing the space occupied by the filtration and settling of slaughterhouse wastewater. When there is a lot of sediment in the settling tank, the mounting plate 2 can be removed so that the mounting plate 2 will not affect the cleaning of sediment.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
