Slaughterhouse wastewater has a large water volume, uneven drainage, high concentration, and many impurities and suspended solids. Therefore, a screen is needed to perform an initial filtration of the wastewater before discharge.

[0004] When the screen device is in use, it is installed at the wastewater outlet where it needs to be discharged.

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] See also Figure 1-4 The present invention provides a technical solution: a sewage filtering device for environmental planning engineering, comprising a support frame 1, a plurality of grating plates 2 are arranged inside the support frame 1, and the tops and bottoms of the plurality of grating plates 2 are staggered, and the tops and bottoms of the grating plates 2 are staggered through the grating slots thereon, so as to filter debris such as minced meat, feathers, and feces in the wastewater, and a connecting device 3 is provided inside the support frame 1 for driving the plurality of grating plates 2 to move, and the connecting device 3 can drive the plurality of grating plates 2 to move in steps and horizontally along the top and bottom of the support frame 1 respectively;

[0043] A driving device 4 that can drive the connecting device 3 to move is provided on the top of the support frame 1, and a pressure wheel 5 is provided on the top of the support frame 1, and both ends of the pressure wheel 5 are rotatably connected to the inner side of the support frame 1 through bearings. The pressure wheel 5 can squeeze the moisture of the debris on the grid plate 2, and the driving device 4 drives the pressure wheel 5 to rotate. A cleaning device 6 that can clean the surface of the grid plate 2 is provided at the bottom of the support frame 1. The cleaning device 6 can clean the waste and grease on the surface of the grid plate 2, and the driving device 4 can drive the cleaning device 6 to move;

[0044] An auxiliary device 7 is provided on the grid plate 2, which can assist the pressing wheel 5 in pressing the surface of the grid plate 2;

[0045] The grille plate 2 is set in the shape of a 7. When in use, the entire device is installed on the top through the support frame 1, and the bottom of the support frame 1 is set at the bottom of the wastewater, so that the wastewater can be filtered and the debris can be taken out from the inside of the wastewater through the grille;

[0046] The driving device 4 is provided to drive the connecting device 3 to move, and the connecting device 3 drives the multiple grid plates 2 to move in a circular manner along the inner side of the support frame 1. Under the action of the connecting device 3, the multiple grid plates 2 move upward from the bottom in a stepped manner on the side of the support frame 1 close to the wastewater, so that it is more convenient to remove debris in the water without affecting the filtration and transmission of the wastewater.

[0047] When the multiple grid plates 2 move to the top of the support frame 1 and the side away from the wastewater, they are transported in a plane, which makes it easier for the pressing wheel 5 and the cleaning device 6 to clean the hair, minced meat, etc. on their surface;

[0048] When in use, the stepped grid plate 2 is driven by the connecting device 3 to move to the top of the support frame 1, and the auxiliary device 7 rotates, so that the auxiliary device 7 and the grid slot on the grid plate 2 are in a plane. Then, when it moves to the bottom of the pressing wheel 5, the driving device 4 drives the pressing wheel 5 to move. The rotation of the pressing wheel 5 can squeeze the surface of the flat grid plate 2 to squeeze out excess moisture in feathers, minced meat, etc., and then the squeezed debris will fall from the top of the support frame 1 during the transmission process;

[0049] When the grid plate 2 passes through the cleaning device 6, the cleaning device 6 can clean the surface of the grid plate 2 to prevent fried objects and grease from sticking to the surface, which would affect its use.

[0050] Before the grid plate 2 enters the wastewater, the auxiliary equipment rotates and is placed alternately with the grid slots on the grid plate 2, which will not affect the transmission of the wastewater and ultimately complete the filtration of the wastewater.

[0051] The connecting device 3 includes a moving chain 30 respectively arranged on both sides of the inner side of the support frame 1, and a plurality of moving wheels 31 are fixed on the moving chain 30. The moving wheels are slidably connected to the inner side of the support frame 1, and the outer sides of the moving wheels are rotatably connected to the outer side of the top of the grid plate 2 through bearings;

[0052] A positioning track 32 is fixed on both sides of the support frame 1. The positioning track 32 is set as an irregular arc track, and the distance between the positioning track 32 and the moving chain 30 begins to deform from the inclined section at the bottom of the support frame 1 and becomes smaller. When it is about to reach the horizontal section at the top of the support frame 1, it deforms again and returns to a large distance. Both sides of the bottom of the grid plate 2 are rotatably connected to the moving wheel 2 33 through bearings, and the moving wheel 2 33 slides inside the positioning track 32;

[0053] When in use, the driving device 4 drives the moving chain 30 to move along the outer side of the support frame 1 through the moving wheel 1 31, so that the moving chain 30 can drive the multiple moving wheels 1 31 and the grid plate 2 to move, and the grid plate 2 drives the moving wheel 2 33 to slide along the positioning track 32;

[0054] When the positioning track 32 moves from the bottom to the top of the support frame 1, the second moving wheel 33 rotates at the position where the spacing between the positioning track 32 becomes smaller, so that the multiple grid plates 2 can move in the shape of multiple staggered steps, and remove feathers, minced meat, etc. from the wastewater;

[0055] When the grating plate 2 moves to the position at the top of the support frame 1, the moving wheel 2 33 moves to the position where the spacing between the positioning rails 32 becomes larger, and the grating plate 2 rotates, so that multiple grating plates 2 can be transported in a plane position. When the position of the small-pitch arc track is encountered again, the grating plate 2 moves in a stepped manner, so that multiple grating plates 2 can filter the wastewater.

[0056] The driving device 4 includes rotating wheels 40 arranged at the bottom and top of the moving chain 30, and the rotating wheels 40 are provided with grooves 41 that engage with the outer side of the moving wheel 31;

[0057] The centers of the two bottom rotating wheels 40 and the two top rotating wheels 40 are respectively fixedly connected with a bottom connecting rod 42 and a top connecting rod 43. Both ends of the bottom connecting rod 42 are rotatably connected to the inner side of the support frame 1 through bearings, and one end of the top connecting rod 43 is rotatably connected to the inner side of the support frame 1 through a bearing.

[0058] The other end of the top connecting rod 43 is fixedly connected to a driving motor 44, which is fixedly connected to the outer side of the support frame 1 through a motor frame. One end of the top connecting rod 43 and the bottom connecting rod 42 are both fixedly connected to a driving gear 45, and a transmission gear chain 46 is meshed between the two driving gears 45;

[0059] The two ends of the top connecting rod 43 are respectively connected to a driving member 1 47 and a driving member 2 48 that can drive the pressing wheel 5 and the cleaning device 6 to move.

[0060] The driving member 1 47 includes a moving gear 470 fixed to one end of the top connecting rod 43 and one end of the pressure wheel 5 respectively, and a transmission gear chain 2 471 is meshed and connected between the two moving gears 470.

[0061] The second driving member 48 includes fixed gears 480 fixed to one end of the top connecting rod 43 and the outside of the cleaning device 6 respectively, and the outsides of the two fixed gears 480 are meshed with a transmission gear chain 3 481.

[0062] The cleaning device 6 includes a cleaning brush 60 provided at the bottom of the support frame 1. Both ends of the cleaning brush 60 are rotatably connected to the inner side of the support frame 1 through bearings, and either end of the cleaning brush 60 is fixedly sleeved with the center of the fixed gear 480.

[0063] A rotating wheel 61 is provided at the bottom of the cleaning brush 60, and a plurality of scrapers 62 are fixed to the outside of the rotating wheel 61. The outside of the scrapers 62 is slidably connected to the surface of the grid plate 2. Both ends of the rotating wheel 61 are rotatably connected to the inner side of the support frame 1 through bearings. One end of the rotating wheel 61 and one end of the cleaning brush 60 are respectively sleeved with a transmission gear 63, and a transmission gear chain 64 is meshed between the two transmission gears 63;

[0064] When in use, the drive motor 44 is turned on, and the drive motor 44 drives the top connecting rod 43, the driving gear 45, the transmission gear chain 1 46 and the bottom connecting rod 42 to rotate, and the bottom connecting rod 42 and the bottom connecting rod 42 drive the two bottom moving wheels and the two top moving wheels to rotate, and when the moving wheels rotate, they drive the moving wheel 1 31 to rotate through the groove 41, and the moving wheel 1 31 drives the moving chain 30 to rotate, and the moving chain 30 drives the grille plate 2 to move along the support frame 1;

[0065] The top connecting rod 43 can also drive the moving gear 470 to rotate while rotating, and the moving gear 470 drives the transmission gear chain 2 471 to rotate, and the transmission gear chain 2 471 drives another moving gear 470 to rotate, and the other moving gear 470 drives the pressing wheel 5 to rotate. When the pressing wheel 5 rotates, it squeezes the top of the grille plate 2 to squeeze out the moisture in the debris;

[0066] The top connecting rod 43 simultaneously drives the fixed gear 480 to rotate, the fixed gear 480 drives the transmission gear chain 3 481 to rotate, the transmission gear chain 3 481 drives another fixed gear 480 to rotate, the fixed gear 480 drives the cleaning brush 60 to rotate, and the cleaning brush 60 rotates to clean the flat grille surface.

[0067] The cleaning brush 60 drives the transmission gear 63 to rotate, the transmission gear 63 drives the transmission gear chain 4 64 to rotate, the transmission gear chain 4 64 drives another transmission gear 63 to rotate, the transmission gear 63 drives the rotating wheel 61 to rotate, and the rotating wheel 61 drives different scrapers 62 to contact the surface of the grille plate 2 to remove the grease on the surface of the grille plate 2;

[0068] Furthermore, the cleaning brush 60 and the scraper 62 come into contact with each other during rotation, so that the cleaning brush 60 can also clean the grease on the scraper 62;

[0069] The bottom of the support frame 1 is arranged in an arc shape, and the cleaning brush 60 is arranged in a depression at the bottom of the support frame 1, so that part of the waste can fall out from the top of the support frame 1 during transportation, which can reduce the cleaning burden of the cleaning brush 60.

[0070] The auxiliary device 7 includes a plurality of rotating plates 70 arranged on the inner side of the grid plate 2. The plurality of rotating plates 70 are respectively arranged inside the plurality of grid slots, and a rotating rod 71 is fixedly connected between the plurality of rotating plates 70. The rotating rod 71 is rotatably connected to the grid plate 2 via a bearing.

[0071] Both ends of the rotating rod 71 pass through the grille plate 2 and are fixedly connected to the protrusion 72. A protrusion 73 that can squeeze the protrusion 72 is fixedly provided on the inner side of the top of the support frame 1. The end of the protrusion 73 close to the protrusion 72 is set in an inclined shape, which makes it more convenient to squeeze the first protrusion 72. The protrusion 73 is parallel to the positioning track 32 and will not restrict the movement of the grille plate 2.

[0072] Limiting members 74 are provided on both sides of the grid plate 2 , and the limiting members 74 can limit the rotation angle of the rotating rod 71 .

[0073] The limiting member 74 includes a fan-shaped groove 740 provided inside the grille plate 2 on both sides. A clamping rod 742 is fixedly connected to the outer side of each end of the rotating rod 71. The clamping rod 742 is fixedly connected to the inside of the fan-shaped groove 740 with a compression spring 741. The compression spring 741 can keep the rotating plate 70 tilted toward the inner side of the grille plate 2.

[0074] When the grille plate 2 moves to the convex plate 73, the convex plate 73 presses the rotating plate 70 through the protrusion 72, so that the rotating plate 70 rotates to a position on the same plane as the grille plate 2, filling the grille grooves on the grille plate 2. This can prevent the grille grooves from being blocked by gravity or debris when the grille plate 2 moves to the top of the support frame 1;

[0075] When the pressing wheel 5 squeezes the debris on the grid plate 2, it can support the debris to prevent it from falling off the grid plate 2;

[0076] Thus, the rotating plate 70 can move in a plane with the grille plate 2 from the cleaning brush 60 and the partition, thereby assisting the cleaning brush 60 and the scraper 62 to clean the surface of the grille plate 2. When the rotating plate 70 moves out of the position of the convex plate 73, it rotates back to the initial position and tilts toward the inner side of the grille plate 2. The staggered placement with the grille grooves on the grille plate 2 will not affect the transmission of wastewater.

[0077] In this solution, the circuit operation is an existing conventional circuit, and the circuits and controls involved in the present invention are all existing technologies, which will not be described in detail here.
