Description

Technical Field

[0001] This utility model relates to the field of rapid unloading technology in sludge dewatering workshops, and in particular to a rapid unloading device for sludge dewatering workshops. Background Technology

[0002] Sludge dewatering is a sludge treatment method that removes water from fluidized raw, concentrated, or digested sludge, transforming it into semi-solid or solid sludge blocks. After dewatering, the sludge moisture content can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dewatering equipment. After dewatering, the sludge and wastewater need to be discharged.

[0003] Common sludge dewatering workshop rapid unloading devices only include unloading functions, capable of unloading sludge and wastewater, but lack the function of adjusting the size of the discharge port. This cannot guarantee the efficiency of sludge discharge. When operating at low flow rates, the flow velocity of sludge and water in the discharge channel decreases, and sludge accumulation becomes more severe. In addition, the sludge concentration in the area increases due to the subsequent inflow of sludge discharge water. When operating at high flow rates, the residence time of the sludge discharge water is too short, directly causing the sludge level to rise and the velocity to increase, resulting in a shrinking sedimentation space. Combined with the effect of high flow velocity, this ultimately causes the sludge in the sedimentation zone to float to the surface, affecting the problem of efficient sludge discharge.

[0004] Therefore, to address the lack of adjustment function for the discharge port size in the aforementioned rapid unloading device for sludge dewatering workshops, a rapid unloading device for sludge dewatering workshops can be designed. When it is necessary to narrow the discharge port according to the water level and sludge deposition, the external PLC controller controls the motor to start, and the motor drives the lead screw to rotate. The rotating lead screw drives the discharge section plate to move upward until the discharge section plate moves to the opening of the horizontal discharge pipe and fits against the opening of the horizontal discharge pipe. Wastewater will then be discharged from the narrowed discharge port. When it is necessary to widen the discharge port according to the water level and sludge deposition, the rotating lead screw drives the discharge section plate to move downward until it returns to its original position, ensuring the efficiency of sludge discharge. Utility Model Content

[0005] To overcome the common problem of rapid unloading devices in sludge dewatering workshops lacking the function of adjusting the discharge port size, which cannot guarantee the efficiency of sludge discharge, it is easy to encounter situations where, during low-flow operation, the sludge flow velocity in the sludge discharge channel decreases, and the sedimentation becomes more serious. In addition, the sludge concentration in the area increases due to the subsequent inflow of sludge discharge water. During high-flow operation, the residence time of the sludge discharge water is too short, which directly leads to the sludge level rising and the velocity increasing, resulting in a shrinking sedimentation space. Combined with the effect of high flow velocity, this ultimately causes the sludge in the sedimentation zone to float to the surface, affecting the efficient sludge discharge.

[0006] The technical solution of this utility model is as follows: a rapid unloading device for a sludge dewatering workshop, including a vertical unloading pipe; it also includes a support plate, a discharge section plate, a discharge constriction, an internal threaded hole, a lead screw, a limiting block, and a horizontal unloading pipe. The bottom of the vertical unloading pipe is connected to the horizontal unloading pipe. A support plate is provided above the horizontal unloading pipe. Two lead screws are symmetrically arranged at the front and rear ends of the right side below the support plate. A discharge section plate is provided on the right side below the support plate corresponding to the position of the lead screws. A discharge constriction is opened through the center of the right side of the discharge section plate. Two internal threaded holes are symmetrically opened on the front and rear sides of the top of the discharge section plate. The bottom end of the lead screw is connected to the limiting block through the internal threaded hole.

[0007] Preferably, a MRLF100 level sensor connected to an external PLC controller detects the water level and sludge deposition, transmitting the results to the external PLC controller. When it is necessary to narrow the sludge discharge port based on the water level and sludge deposition, the external PLC controller starts the motor, which drives the lead screw to rotate. The rotating lead screw moves the discharge section plate upward until it reaches and contacts the opening of the horizontal discharge pipe, allowing wastewater to drain from the narrowed discharge port. When it is necessary to widen the sludge discharge port based on the water level and sludge deposition, the rotating lead screw moves the discharge section plate upward. The panel moves downwards until it resets to ensure efficient sludge discharge. This addresses the common problem of rapid unloading devices in sludge dewatering workshops that only include unloading functionality, capable of discharging sludge and wastewater, but lack the ability to adjust the size of the discharge port. This makes it difficult to guarantee sludge discharge efficiency. When operating at low flow rates, the sludge flow velocity in the discharge channel decreases, leading to more severe sludge accumulation. In addition, the subsequent inflow of sludge discharge water further increases the sludge concentration in this area. When operating at high flow rates, the residence time of the sludge discharge water is too short, directly causing the sludge level to rise and the velocity to increase, resulting in a shrinking sedimentation space. Combined with the high flow velocity, this ultimately causes the sludge in the sedimentation zone to float to the surface, affecting the problem of efficient sludge discharge.

[0008] Preferably, two mounting holes are symmetrically provided at the front and rear ends of the top right side of the support plate, and two motors are symmetrically provided at the front and rear ends of the top right side of the support plate corresponding to the positions of the mounting holes.

[0009] Preferably, the top of the lead screw passes through the mounting hole and connects to the output end at the bottom of the motor.

[0010] Preferably, the top of the support plate has several adjustment holes at equal intervals in the middle, and the top of the support plate has several support rods at equal intervals corresponding to the adjustment holes, with a connecting hole in the middle of the top of each support rod corresponding to the adjustment hole.

[0011] Preferably, the horizontal discharge pipe has several fixing holes around its body corresponding to the position of the adjustment hole. The support rod is screwed into the fixing hole and fixed to the horizontal discharge pipe by passing through the connecting hole and the adjustment hole with bolts.

[0012] Preferably, the vertical discharge pipe is provided with several limit rings at equal intervals around its body, and two connecting rods are symmetrically arranged at the front and rear ends of the left side of the limit ring.

[0013] Preferably, the left end of the connecting rod is connected to a limiting plate, and the front and rear ends of the right side of the limiting plate are provided with several limiting holes at equal intervals.

[0014] The beneficial effects of this utility model are:

[0015] 1. A MRLF100 level sensor connected to an external PLC controller detects water level and sludge deposition, transmitting the results to the PLC controller. When the sludge discharge port needs to be narrowed based on water level and sludge deposition, the external PLC controller starts the motor, which drives the lead screw to rotate. The rotating lead screw moves the discharge section plate upwards until it reaches and contacts the opening of the horizontal discharge pipe, allowing wastewater to drain from the narrowed discharge port. When the sludge discharge port needs to be widened based on water level and sludge deposition, the rotating lead screw moves the discharge section plate upwards. The plate moves downwards until it resets, ensuring efficient sludge discharge. This addresses the common problem of rapid unloading devices in sludge dewatering workshops that only include unloading functionality, capable of discharging sludge and wastewater, but lack the ability to adjust the size of the discharge port. This makes it difficult to guarantee efficient sludge discharge. When operating at low flow rates, the sludge flow velocity in the discharge channel decreases, leading to more severe sludge accumulation. In addition, the subsequent inflow of sludge discharge water further increases the sludge concentration in this area. When operating at high flow rates, the residence time of the sludge discharge water is too short, directly causing the sludge level to rise and the velocity to increase, resulting in a shrinking sedimentation space. Combined with the effect of high flow velocity, this ultimately causes the sludge in the sedimentation zone to float to the surface, affecting the problem of efficient sludge discharge.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a rapid unloading device for a sludge dewatering workshop, including a vertical unloading pipe 1; it also includes a support plate 2, a discharge section plate 5, a discharge constriction 6, an internal threaded hole 7, a lead screw 8, a limiting block 9, and a horizontal unloading pipe 19. The bottom of the vertical unloading pipe 1 is connected to the horizontal unloading pipe 19. The support plate 2 is arranged above the horizontal unloading pipe 19. Two lead screws 8 are symmetrically arranged at the front and rear ends of the right side below the support plate 2. The discharge section plate 5 is arranged on the right side below the support plate 2 corresponding to the position of the lead screws 8. A discharge constriction 6 is provided through the center of the right side of panel 5. Two internal threaded holes 7 are symmetrically provided on the front and rear sides of the top of the discharge section plate 5. The bottom end of the lead screw 8 passes through the internal threaded hole 7 and is connected to a limit block 9. The water level and sludge deposition are detected by a liquid level sensor (model MRLF100) connected to an external PLC controller, and the detection results are transmitted to the external PLC controller. When it is necessary to narrow the discharge port according to the water level and sludge deposition, the external PLC controller controls the motor 4 to start. The motor 4 drives the lead screw 8 to rotate, which in turn moves the discharge section plate 5 upward until it reaches the opening of the horizontal discharge pipe 19 and comes into contact with it. Wastewater then exits through the discharge constriction 6. When the discharge opening needs to be enlarged based on water level and sludge deposition, the rotating lead screw 8 moves the discharge section plate 5 downward until it returns to its original position, ensuring efficient sludge discharge. This addresses the common problem of rapid unloading devices in sludge dewatering workshops, which only include unloading functionality and can handle... The system discharges sludge and wastewater, but lacks the function of adjusting the size of the discharge port, which cannot guarantee the efficiency of sludge discharge. When the flow rate is low, the flow velocity of the sludge in the discharge channel decreases, and the sedimentation becomes more serious. In addition, the sludge concentration in the area increases due to the subsequent discharge water. When the flow rate is high, the residence time of the discharge water is too short, which directly leads to the sludge level rising and the velocity increasing, resulting in less and less sedimentation space. In addition, the high flow velocity eventually causes the sludge in the sedimentation zone to float to the surface, affecting the problem of efficient sludge discharge.

[0024] Please see Figures 2-5 In this embodiment, a plurality of adjustment holes 10 are equally spaced at the center of the top of the support plate 2. A plurality of support rods 11 are equally spaced at the top of the support plate 2 corresponding to the adjustment holes 10. A connecting hole 12 is opened at the center of the top of the support rod 11 corresponding to the adjustment hole 10. A plurality of fixing holes 14 are opened around the horizontal discharge pipe 19 corresponding to the adjustment holes 10. The support rods 11 are fixed to the horizontal discharge pipe 19 by bolts 13 passing through the connecting holes 12 and the adjustment holes 10 and then screwed into the fixing holes 14. Several limit rings 15 are arranged at equal intervals. Two connecting rods 16 are symmetrically arranged at the front and rear ends of the left side of the limit rings 15. The left end of the connecting rod 16 is connected to the limit plate 17. Several limit holes 18 are opened at equal intervals at the front and rear ends of the right side of the limit plate 17. During unloading, the horizontal unloading pipe 19 is supported by the support rod 11 placed horizontally on the sewage ditch, while the limit plate 17 is fixed to the wall and the vertical unloading pipe 1 is positioned by the limit rings 15, thereby ensuring the stability of the vertical unloading pipe 1 and the horizontal unloading pipe 19 during unloading.

[0025] Please see Figures 1-5 In this embodiment, two mounting holes 3 are symmetrically provided at the front and rear ends of the top right side of the support plate 2. Two motors 4 are symmetrically arranged at the front and rear ends of the top right side of the support plate 2 corresponding to the mounting holes 3. The top end of the lead screw 8 passes through the mounting hole 3 and is connected to the output end of the bottom of the motor 4. During unloading, the water level and sludge deposition are detected by a liquid level sensor (model MRLF100) connected to an external PLC controller, and the detection results are transmitted to the external PLC controller. When it is necessary to narrow the sludge discharge port according to the water level and sludge deposition, the external PLC controller controls the motor 4 to start. The motor 4 drives the lead screw 8 to rotate. The rotating lead screw 8 drives the discharge section plate 5 to move upward until the discharge section plate 5 moves upward. The screw 8 moves to the opening of the horizontal discharge pipe 19 and fits against the opening of the horizontal discharge pipe 19. The sewage will then be discharged from the discharge constriction 6. When it is necessary to enlarge the discharge port according to the water level and sludge deposition, the rotating screw 8 will drive the discharge section plate 5 to move downward until it is reset, ensuring the efficiency of sludge discharge and realizing the function of adjusting the size of the discharge port. This prevents the sludge water flow speed in the sludge discharge channel from decreasing during low flow operation, which would lead to more serious sludge accumulation. In addition, the sludge concentration in the area will increase due to the subsequent sludge discharge water. During high flow operation, the residence time of the sludge discharge water is too short, which directly leads to the sludge level rising and the speed increasing, resulting in a smaller and smaller sedimentation space. In addition, the large flow velocity will eventually cause the sludge in the sedimentation area to float, affecting the problem of efficient sludge discharge.

[0026] During operation, the horizontal unloading pipe 19 is supported by a support rod 11 placed horizontally on the sewage ditch, while the limiting plate 17 is fixed to the wall and the vertical unloading pipe 1 is positioned by a limiting ring 15, thus ensuring the stability of the vertical and horizontal unloading pipes 19 during unloading. A liquid level sensor (model MRLF100) connected to an external PLC controller detects the water level and sludge deposition, transmitting the results to the external PLC controller. Adjustments are made based on the water level and sludge deposition as needed. When the sludge discharge port narrows, the external PLC controller starts the motor 4, which drives the lead screw 8 to rotate. The rotating lead screw 8 then moves the discharge section plate 5 upward until it reaches the opening of the horizontal discharge pipe 19 and fits against it. Sewage will then be discharged from the narrowed discharge port 6. When it is necessary to enlarge the sludge discharge port according to the water level and sludge deposition, the rotating lead screw 8 moves the discharge section plate 5 downward until it is reset, ensuring the efficiency of sludge discharge and realizing the function of adjusting the size of the discharge port.

[0027] Through the above steps, a liquid level sensor (model MRLF100) connected to an external PLC controller detects the water level and sludge deposition, and transmits the detection results to the external PLC controller. When it is necessary to narrow the sludge discharge port according to the water level and sludge deposition, the external PLC controller controls the motor 4 to start. The motor 4 drives the lead screw 8 to rotate, and the rotating lead screw 8 moves the discharge section plate 5 upward until it moves to the opening of the horizontal discharge pipe 19 and fits against the opening of the horizontal discharge pipe 19. The sewage will then be discharged from the discharge narrowing port 6. When it is necessary to widen the sludge discharge port according to the water level and sludge deposition, the rotating lead screw... 8 drives the discharge section plate 5 downwards until it resets, ensuring the efficiency of sludge discharge. This solves the problem of common sludge dewatering workshop rapid unloading devices that only include the unloading function, which can unload sludge and sewage, but lack the function of adjusting the size of the discharge port. This makes it impossible to guarantee the efficiency of sludge discharge. When the flow rate is low, the speed of the sludge water flow in the sludge discharge channel decreases, and the sedimentation becomes more serious. In addition, the sludge concentration in the area increases due to the subsequent sludge discharge water. When the flow rate is high, the residence time of the sludge water is too short, which directly leads to the sludge level rising and the speed increasing, resulting in the sedimentation space becoming smaller and smaller. In addition, the high flow velocity eventually causes the sludge in the sedimentation zone to float, affecting the problem of efficient sludge discharge.
