Description

Technical Field

[0001] This utility model relates to the field of mud dewatering technology, and in particular to a mud dewatering device with pressure regulation. Background Technology

[0002] Sludge dewatering removes water from fluid raw, concentrated, or digested sludge, transforming it into semi-solid or solid sludge blocks. In construction processes such as tunnel engineering, sludge dewatering is necessary.

[0003] A search revealed a Chinese patent (application number "202123277981.9") disclosing "a screw press sludge dewatering machine." This sludge dewatering machine includes support rods, a processing chamber, a drive motor, a feed pipe, a cleaning component, a rotating shaft, and a discharge pipe. The support rods are symmetrically arranged below the processing chamber. The drive motor is located on the outer surface of the processing chamber. The rotating shaft is rotatably disposed between the inner walls of the processing chamber and fixedly connected to the drive motor. The feed pipe is located at the top of the processing chamber near the drive motor. The cleaning component is located at the top of the processing chamber. However, this sludge dewatering machine cannot compress the dewatered sludge during dewatering, leaving a significant amount of residual moisture in the sludge, which is detrimental to subsequent sludge treatment and results in low practicality. Utility Model Content

[0004] This invention provides a sludge dewatering device with pressure regulation, which solves the problem that the separation device proposed in the prior art cannot squeeze the dewatered sludge during sludge dewatering, leaving a lot of water in the sludge, which is not conducive to subsequent sludge treatment and has low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pressure-regulated mud dewatering device includes a base with a mounting frame on top. The mounting frame includes a fixed seat welded to the outer wall of the base top, a first mounting seat welded to the outer wall of the base top, a second mounting seat welded to the outer wall of the base top, and guide frames bolted to the outer walls of the first and second mounting seats on opposite sides. A dewatering mechanism is provided between the fixed seat and the second mounting seat. The dewatering mechanism includes a dewatering cylinder with equally spaced drainage holes on its lower outer wall, a stacked screw shaft with progressively decreasing pitch, and a reduction motor bolted to the outer wall of one side of the first mounting seat. A transmission mechanism is provided on one side of the first mounting seat, the transmission mechanism including a servo motor bolted to the outer wall of one side of the first mounting seat, and a transmission mechanism that... The coupling connects to a connecting shaft at one end of the servo motor output shaft, a drive gear connected to the outer wall of the connecting shaft via a key, a mounting cylinder connected to the outer wall of one side of the first mounting base via a flange, a gear ring meshing with the drive gear to form a transmission engagement, and a fixing ring welded to the inner wall of the mounting cylinder. A pressure regulating assembly is provided outside the mounting cylinder. The pressure regulating assembly includes a compression ring slidably mounted on the outer wall of the mounting cylinder, three screws respectively passing through and screwed to the outer wall of the compression ring, and three driven gears respectively meshing with the gear ring to form a transmission engagement. A compression assembly is provided at one end of the mounting cylinder. The compression assembly includes a slide cylinder slidably mounted on the outer wall of the mounting cylinder, a compression plate welded to the outer wall of one end of the slide cylinder, and a spring sleeved on the outer wall of the slide cylinder. A discharge mechanism is provided below the compression plate.

[0006] Preferably, two reinforcing plates are bolted to one side of the outer wall of the fixed base, and the two reinforcing plates are respectively bolted to the top outer wall of the base. A mounting bracket is welded to the top outer wall of the base, and the first mounting base and the second mounting base are respectively welded to the outer walls of the mounting bracket on both sides. A drain pipe is fixed to the bottom inner wall of the guide frame.

[0007] Preferably, the two sides of the dewatering cylinder are respectively connected to the outer walls of the fixed seat and the second mounting seat on opposite sides via flanges, and the two ends of the stacked screw main shaft are respectively connected to the outer walls of the fixed seat and the first mounting seat via bearings. One end of the stacked screw main shaft is connected to the gearbox of the geared motor via a flat key.

[0008] The above scheme involves feeding sludge into the dewatering cylinder via a feed hopper. A geared motor drives the screw press spindle to rotate, which in turn transports the sludge. During the transport process, sludge and mud-water are separated. Simultaneously, the screw pitch of the screw press spindle is reduced, which compresses the sludge during transport, accelerating the separation speed. The mud-water is then discharged through the guide frame.

[0009] Preferably, a fixing plate is welded to the inner wall of the middle part of the mounting frame, and one end of the connecting shaft passes through and is connected to the outer wall of the fixing plate through a bearing, and the gear ring is connected to the outer wall of the mounting cylinder through a bearing.

[0010] Preferably, the three screws are respectively connected to the outer walls of the first and second mounting bases through bearings at both ends, and the three driven gears are respectively connected to the outer walls of the three screws through flat keys.

[0011] Preferably, one end of the spring abuts against the outer wall of one side of the extrusion ring, and a plurality of limiting rods are welded to the outer wall of one side of the extrusion plate, and the plurality of limiting rods pass through and are slidably installed on the outer wall of the fixed ring respectively.

[0012] The above scheme involves conveying sludge to one side of the extrusion plate via the screw press spindle. As the screw press spindle continues to convey the sludge, it accumulates on one side of the extrusion plate. Under the action of spring tension, the extrusion plate squeezes the sludge, causing the water in the sludge to be squeezed out. Subsequently, the pressure of the sludge on the extrusion plate exceeds the tension of the spring, causing the extrusion plate to move and discharge the sludge. The output shaft of the servo motor drives the drive gear to rotate, which in turn drives the gear ring to rotate. The gear ring drives the three driven gears to rotate, which in turn drives the three screws to rotate synchronously. The screws drive the extrusion ring to slide on the outer wall of the mounting cylinder, squeezing the spring and adjusting the tension of the spring, thereby adjusting the pressure of the extrusion plate on the sludge.

[0013] Preferably, the unloading mechanism includes an unloading pipe bolted to the outer walls of the first mounting base and the second mounting base, an unloading motor bolted to the outer wall of one side of the first mounting base, an auger connected to one end of the output shaft of the unloading motor via a coupling, and a discharge pipe welded to the inner wall of one end of the bottom of the unloading pipe. An installation port is opened on the upper outer wall of one end of the unloading pipe, and a collection frame is welded inside the installation port. One end of the auger passes through and is connected to the outer wall of the second mounting base via a bearing.

[0014] The above scheme involves collecting the sludge after squeezing and dewatering using a collection frame. Then, the output shaft of the unloading motor drives the auger to rotate, and the auger transports the sludge in the unloading pipe, which is then discharged through the discharge pipe.

[0015] The beneficial effects of this utility model are as follows: Sludge accumulates on one side of the extrusion plate. Under the action of spring tension, the extrusion plate squeezes the sludge, squeezing out the water. Subsequently, the pressure of the sludge on the extrusion plate exceeds the spring tension, causing the extrusion plate to move and discharge the sludge. The output shaft of the servo motor drives the drive gear to rotate, which in turn drives the gear ring to rotate. The gear ring drives three driven gears to rotate, which in turn drives three screws to rotate synchronously. The screws drive the extrusion ring to slide on the outer wall of the mounting cylinder, squeezing the spring and adjusting the spring tension, thereby adjusting the pressure of the extrusion plate on the sludge. This allows for the extrusion and dewatering of the dewatered sludge, further reducing the water content in the sludge. At the same time, the pressure can be adjusted, improving practicality.

[0029] Working principle: The feed hopper 302 conveys the slurry into the dewatering cylinder 301. The geared motor 304 drives the screw press main shaft 303 to rotate, conveying the slurry. During the conveying process, sludge and mud-water separation are achieved. At the same time, the screw pitch of the screw press main shaft 303 decreases, compressing the slurry during the conveying process and accelerating the separation speed. The mud-water is discharged through the guide frame 205. The screw press main shaft 303 conveys the sludge to one side of the extrusion plate 602. As the screw press main shaft 303 continues to convey, the sludge accumulates on one side of the extrusion plate 602. Under the tension of the spring 603, the extrusion plate 602 compresses the sludge, squeezing out the water from the sludge. When the pressure of the sludge on the extrusion plate 603 exceeds that of the spring 603... When tension is applied, the extrusion plate 602 moves to discharge the sludge. The output shaft of the servo motor 401 drives the drive gear 403 to rotate, which in turn drives the gear ring 406 to rotate. The gear ring 406 drives the three driven gears 503 to rotate, which in turn drives the three screws 502 to rotate synchronously. The screws 502 drive the extrusion ring 501 to slide on the outer wall of the mounting cylinder 405, extruding the spring 603 and adjusting the tension of the spring 603, thereby adjusting the pressure of the extrusion plate 602 on the sludge. The collection frame collects the sludge after extrusion and dewatering. Then, the output shaft of the discharge motor 702 drives the auger 703 to rotate, which transports the sludge in the discharge pipe 701 and then discharges it through the discharge pipe 704.
