Description

Technical Field

[0001] This invention relates to the field of bar screen technology, specifically a bar screen device for intercepting floating debris at the wastewater discharge outlet of a broiler processing plant. Background Technology

[0002] The wastewater discharge outlet of a broiler processing plant is a critical legal point for the discharge of high-concentration organic wastewater generated throughout the entire process of slaughtering, cutting, eviscerating, and cleaning. This wastewater undergoes multi-stage treatment, including slag removal by grilling, oil separation and sedimentation, air flotation for oil removal, biochemical degradation, and deep purification, before being discharged to the outside environment and consistently meeting environmental standards. It is typically located at the end of the plant's wastewater treatment station, transported via open channels, and ultimately discharged into the municipal sewage network, centralized wastewater treatment facilities within the industrial park, or a qualified natural receiving water body. Clear signage must be displayed at the discharge outlet to ensure compliance with environmental regulations.

[0003] However, the existing technology has the following shortcomings: When sewage enters the open channel, the floating objects will accumulate in this area due to inertia because the channel width narrows. This is the best location for the screen to intercept the floating objects. Although the screen is installed, the sewage carries floating objects such as blood lipids, feathers, meat scraps, and feces. Moreover, the production water volume fluctuates greatly with the performance. Traditional screens cannot automatically adjust the interception efficiency according to the water volume changes, resulting in some floating objects being not completely intercepted and leaking out when the water volume of the open channel fluctuates. Summary of the Invention

[0004] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 Appendix Figure 8 Appendix Figure 9 As shown:

[0035] This embodiment provides a floating debris interception grid device for wastewater discharge outlets of broiler processing plants, including a floating debris treatment device 1. The floating debris treatment device 1 has an open channel 11 downstream of the discharge outlet. A covering cleaning device 12 is installed on the open channel 11 downstream of the discharge outlet. A floating debris treatment device 13 is installed directly below the covering cleaning device 12. A water flow deceleration section 112 is formed in the open channel 11 downstream of the discharge outlet. Flow measuring guide plates 111 are installed on both walls of the water flow deceleration section 112.

[0036] Furthermore, the flow guide plate 111 is mainly installed in the water flow deceleration section 112, forming a relatively fixed shape on the inner wall and located in front of the floating treatment device 13, for guiding the floating objects to gather.

[0037] Furthermore, the water flow deceleration section 112 is set 1-2m downstream of the discharge outlet. After the water flows into the open channel at high speed from the discharge outlet, the water flow speed decreases due to the narrowing of the channel width. Floating objects will gather in this area due to inertia. Therefore, a floating treatment device 13 is set up again.

[0038] The floating treatment device 13 is provided with an even array of concrete bases 131, each of which is fixed with a support leg 132. A frame 133 is fixed above the support leg 132, and a treatment grid assembly 134 is installed on the frame 133.

[0039] Furthermore, the concrete base 131 is mainly poured into the open channel 11 downstream of the discharge outlet. It is fixed by pouring and, together with the support leg 132 installed above, is fixed to support the erected frame 133.

[0040] Furthermore, the frame 133 has two hinge ears, which are used to connect with one end of the treatment grid assembly 134 so that the angle can be adjusted accordingly as the water volume changes.

[0041] The processing grid assembly 134 includes a grid frame 1341. Frame-side connecting blocks 1342 are installed on both sides of the grid frame 1341. Frame-top rubber plates 1343 are fixed to both sides of the grid frame 1341. Limiting supports 1344 are installed above the frame-top rubber plates 1343. A screw conveyor 1345 is connected to the bottom of the grid frame 1341. Angle adjustment components 1346 are installed on the frame-side connecting blocks 1342. A floating debris discharge pipe 13451 is installed on the screw conveyor 1345. A drive rod motor 13452 is installed on the screw conveyor 1345.

[0042] Furthermore, the grid frame 1341 is a welded frame made of 304 stainless steel square tubes, and one end of the lower surface is connected to the frame 133 with two hinge ears by a shaft to realize subsequent hinge swing.

[0043] Furthermore, the upper side panel 1343 is a EPDM rubber sealing gasket with a thickness of 10mm, and is tightened with pressure strips and bolts to prevent water from escaping through gaps or floating objects from passing through.

[0044] The flow measuring guide plate 111 is provided with a casting base 1111, a fixed shaft 1112 is installed on the casting base 1111, a guide plate 1113 is embedded in the fixed shaft 1112, a groove 1114 is opened on the surface of the guide plate 1113, a flow measuring impeller 1116 is installed in the guide plate 1113, a signal transmitter 1115 is fixed on the rear wall of the guide plate 1113, and a lock cover 1117 is installed on the top of the guide plate 1113.

[0045] Furthermore, the flow measuring impeller 1116 is mainly used to monitor the water flow rate. It relays the feedback information to the signal transmitter 1115, which then feeds it back to the control box to trigger the angle adjustment component 1346.

[0046] The grid frame 1341 has a card seat 13411 fixed on both lower surfaces. The card seats 13411 are engaged with the matching storage box 13412. The matching storage box 13412 has a box side connecting platform 13413 on its rear wall. The grid frame 1341 has a frame slot 13414 on both the upper and lower surfaces. The frame slot 13414 has an inner frame 13415 installed in each of the frame slots 13414. The inner frame 13415 has several grid strip card seats 13416 arranged in a row. The inner frame 13416 on the upper surface has a coarse grid 13417 installed in the inner frame slot 13416, and the inner frame 13415 on the lower surface has a fine grid 13418 installed in the inner frame slot 13416.

[0047] Furthermore, both the coarse grille 13417 and the fine grille 13418 are engaged with several grid strip holders 13416 arranged in a straight line at both ends, and then secured with bolts.

[0048] Furthermore, the coarse grid 13417 and the fine grid 13418 form a double-layer grid. The coarse grid, with a gap of 15-20mm, is on top, and the fine grid, with a gap of 5-8mm, is on the bottom. The two are staggered at a 15° angle to prevent floating objects from "directly passing" to the lower layer.

[0049] Furthermore, both the coarse grid 13417 and the fine grid 13418 are made of food-grade polyurethane elastomer and are fixed to the grid base plate by embedded slots, which ensures elasticity and prevents them from falling off due to water flow impact.

[0050] The angle adjustment component 1346 is provided with a fixed outer cover 13461, and a push rod fixing seat 13462 is fixed inside the fixed outer cover 13461. An electric push rod 13463 is installed in the push rod fixing seat 13462, and a connecting transmission rod 13464 is connected to the electric push rod 13463.

[0051] Furthermore, the angle adjustment component 1346 is provided with at least two sets, with a stroke of 300mm and a thrust of ≥2kN, and is connected to the frame side connecting blocks 1342 on both sides of the grid frame 1341. The electric control push rod 13463 is driven by a PLC controller and can also be adjusted locally manually or remotely automatically.

[0052] The specific working principle is as follows:

[0053] This invention involves setting up a floating treatment device 13 1-2m downstream of the discharge outlet in an open channel, and then installing it at the water flow deceleration section 112. A cleaning device 12 covers the device. A flow measuring guide plate 111 is cast into the channel wall to form a casting base 1111. After the guide plate 1113 is installed on the fixed shaft 1112, the locking cover 1117 is locked to complete the fixation. The flow measuring impeller 1116 continuously monitors the water flow velocity and sends feedback to the signal transmitter 1115. The control box then triggers the angle adjustment component 1346 in the treatment grid assembly 134 on the frame 133 of the fixed support leg 132 on the concrete base 131, thus fixing the outer protective cover. The electrically controlled push rod 13463 of the push rod fixing seat 13462 in 13461 extends and is driven by the transmission rod 13464 to the frame side connecting block 1342, which drives the grid frame 1341 to cooperate with the electrically controlled push rod 13463 to form an angle adjustment. After adjustment, the floating objects enter the coarse grid 13417 and fine grid 13418 in the grid frame 1341, and then fall directly into the inner fixed frame 13415 set between the slots 13414 on the frame. Then, the drive rod motor 13452 in the screw conveyor 1345 connected to the grid strip card seat 13416 in the frame drives it to form a lifting and finally discharge it directly from the floating object discharge pipe 13451 at the end into the collection box on the docking shore.

[0054] Example 2: As shown in the attached document Figure 4 To be continued Figure 5 Appendix Figure 7 To be continued Figure 8 As shown:

[0055] The grid assembly 134 includes a grid frame 1341, with frame-side connecting blocks 1342 installed on both sides of the grid frame 1341. Upper frame rubber plates 1343 are fixed to both sides of the grid frame 1341, and limit supports 1344 are installed above the upper frame rubber plates 1343. A screw conveyor 1345 is connected to the bottom of the grid frame 1341. Angle adjustment components 1346 are installed on the frame-side connecting blocks 1342. Card seats 13411 are fixed to both sides of the lower surface of the grid frame 1341. Adaptive storage boxes 13412 engage with the card seats 13411, and a box-side connecting platform 13413 is provided on the rear wall of the adaptive storage box 13412.

[0056] The cleaning device 12 is equipped with an even array of support beams 121, a canopy 123 is installed on the even array of support beams 121, an inner frame plate 122 is fixed on the canopy 123, a fixing seat 124 is fixed on the inner wall of one set of support beams 121, a cleaning component 125 is installed between the fixing seats 124, and a control box 126 is installed on the inner frame plate 122.

[0057] Furthermore, the inner frame plate 122 is fixed below the shielding canopy 123, and then the control box 126 is installed on the inner frame plate 122 to allow it to form an electrical connection with the cleaning component 125.

[0058] The cleaning component 125 includes a support frame 1251, a drive motor 1252 fixed to the surface of the support frame 1251, a frame hinged bearing 12511 on the support frame 1251, a first connecting rod 1256 connected to the front of the drive motor 1252, a second connecting rod 1254 hinged to the other end of the first connecting rod 1256, a swing rod 1255 hinged to the other end of the second connecting rod 1254, a hinged locking cover 1253 on the surface of the swing rod 1255, a reciprocating swing block 1257 fixed to the end of the swing rod 1255, an even number of clean water supply pipes 1258 installed above the reciprocating swing block 1257, and an even number of rows of fan-shaped shower heads 1259 arranged in a straight line installed below the reciprocating swing block 1257.

[0059] Furthermore, the drive motor 1252 and the water supply pipe 1258 are both controlled by the control box 126, and are flushed once every 2 hours.

[0060] Furthermore, the drive motor 1252 mainly drives the first connecting rod 1256 to rotate, which in turn drives the second connecting rod 1254 to form a linkage, causing the swing rod 1255 fixed on the surface of the hinged shaft seat 12511 on the frame to swing back and forth, which drives the fan-shaped shower head 1259 to perform rinsing work.

[0061] Furthermore, the water supply pipe 1258 mainly supplies water to the fan-shaped shower head 1259 and connects it to the clean water branch of the processing plant, with a pressure ≥0.3MPa.

[0062] Furthermore, two rows of fan-shaped shower heads 1259 are provided, both fixed below the reciprocating swing block 1257 and connected to the clean water supply pipe 1258 above.

[0063] The specific working principle is as follows:

[0064] This invention uses a control box 126 on the inner frame plate 122 below the canopy 123 to trigger the water supply to the purified water supply pipe 1258 at a time, while simultaneously driving the motor 1252 to work synchronously. The motor 1252 drives the first connecting rod 1256 to rotate, indirectly transmitting the second connecting rod 1254 to pull the swing rod 1255 fixed on the hinged shaft seat 12511 on the frame. This causes the purified water supply pipe 1258 to swing together above the reciprocating swing block 1257, while the water flow is supplied to the fan-shaped shower head 1259. This reciprocating motion simultaneously sprays the surfaces of the coarse grid 13417 and fine grid 13418 directly below. During the spraying process, floating objects fall off and enter the inner fixed frame 13415. Driven by the screw conveyor 1345, they are lifted and, upon reaching the end, are directly discharged from the floating object discharge pipe at the end into the collection box on the docking shore, preventing the grid from clogging.
