Technical Field
[0001] This utility model relates to the field of screw press technology, and in particular to a centrifugal discharge structure for a screw press. Background Technology
[0002] In the fields of modern environmental protection and industrial production, screw presses, as a highly efficient solid-liquid separation device, are gradually becoming an important tool for wastewater and sludge treatment.
[0003] Screw presses achieve sludge concentration, dewatering, and self-cleaning through the rotation of the screw shaft and the filtration effect of the stacked disc structure. Screw presses are compact in design, occupy little space, and feature low energy consumption, high efficiency, and a high degree of automation.
[0004] Currently, during the operation of screw presses, uneven discharge may occur due to fluctuations in feed rate, changes in material properties, or wear of the screw blades. Uneven discharge can affect the stability of subsequent processes, mainly because these processes rely on stable material input; uneven discharge can lead to fluctuations in process parameters. Therefore, improvements are proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 4 As shown, a centrifugal discharge structure for a screw press is disclosed, comprising a screw press body 1, a receiving hopper 3 located below the discharge port of the screw press body 1, the top opening of the receiving hopper 3 being larger than the discharge port of the screw press body 1 to facilitate sludge falling into the receiving hopper 3, and the receiving hopper 3 being fixedly connected to the frame of the screw press body 1, and an auxiliary material cylinder 6 being fixedly connected to the bottom of the receiving hopper 3, the bottom of the auxiliary material cylinder 6 being rotatably fitted with a connecting pipe, the bottom of the connecting pipe being fixedly connected to an auger conveyor. The machine 5 has a connecting pipe including a movable pipe 14, and an auxiliary material cylinder 6 is rotatably sleeved on the outer surface of the movable pipe 14. The movable pipe 14 is fixedly connected to the feed inlet of the screw conveyor 5. An annular rubber pad 15 is fixedly connected to the top of the movable pipe 14, and the annular rubber pad 15 is sealed and abutted against the auxiliary material cylinder 6. The annular rubber pad 15 is set to prevent sludge from entering the gap between the movable pipe 14 and the auxiliary material cylinder 6, reduce the rotational friction between the two, and improve the service life of the movable pipe 14 and the auxiliary material cylinder 6.
[0024] The frame of the screw press body 1 is fixedly connected to a base 2 on one side of the discharge port. The base 2 is equipped with a discharge position adjustment component, which includes a handwheel 8. The handwheel 8 is located on one side of the outer surface of the base 2, and a rubber pad is fixedly connected to the outer surface of the handwheel 8. The rubber pad abuts against the outer wall of the base 2, increasing the rotational resistance of the handwheel 8 and preventing it from shifting under vibration conditions, thus ensuring its effectiveness. If the equipment vibration is large, threaded holes can be made on the outer surface of the handwheel 8 and the outer surface of the base 2, and bolts can be used to fix the handwheel 8 to the base 2, thereby preventing the handwheel 8 from moving when not in use. The number of threaded holes on the base 2 depends on actual needs. As required, a rotating shaft 9 is fixedly connected to one side of the outer surface of the handwheel 8, and the rotating shaft 9 extends through the outer wall of the base 2 to the inside, and is rotatably connected to the base 2. The first bevel gear 10 is fixedly connected to one end of the rotating shaft 9 inside the base 2. A second bevel gear 13 is meshed with one side of the outer surface of the first bevel gear 10. A main shaft 12 is fixedly connected to the center of the second bevel gear 13. The main shaft 12 extends through the inner top wall of the base 2 to the top, and is rotatably connected to the base 2. The main shaft 12 and the base 2 are connected by a bearing. The inner ring of the bearing is fixedly sleeved on the outer surface of the main shaft 12, and the outer ring of the bearing is fixedly connected to the base 2. The bearing provides support for the main shaft 12.
[0025] The movable end of the discharge position adjustment component is fixedly mounted with a support frame, and the auger conveyor 5 is fixedly mounted on the top of the support frame. The support frame includes a movable seat 11, which is fixedly connected to the main shaft 12 and to the outer shell of the auger conveyor 5. A support rod 4 is fixedly connected to one side of the top of the movable seat 11, and the support rod 4 is fixedly connected to the outer shell of the auger conveyor 5. The movable seat 11 and the support rod 4 provide support for the auger conveyor 5, which facilitates the installation of the auger conveyor 5. An annular guide rail 7 is slidably connected to the bottom of the movable seat 11, and the annular guide rail 7 is fixedly mounted on the top of the base 2. The annular guide rail 7 provides support and guidance for the movable seat 11, which can ensure the stability of the movable seat 11 during use.
[0026] Working principle: First, adjust the discharge position of the auger conveyor 5 according to the location of the subsequent sludge treatment equipment. Turn the handwheel 8, which drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the first bevel gear 10 to rotate. The first bevel gear 10 drives the main shaft 12 to rotate through the second bevel gear 13. The main shaft 12 drives the movable seat 11 and the support rod 4 to rotate around the main shaft 12, changing the discharge position of the auger conveyor 5 until the desired position is reached. The screw press body 1 runs to dewater the sludge. Then, centrifugal force and the screw structure are used to discharge the dewatered sludge, allowing it to fall into the receiving hopper 3. Then, it enters the auger conveyor 5 through the auxiliary material cylinder 6 and the movable pipe 14. After a certain period of time, the auger conveyor 5 runs, transporting the incoming sludge to the next sludge treatment equipment.
[0027] It should be noted that, in actual use, the auger conveyor 5 is electrically connected to the electrical control box used by the screw press body 1 to facilitate the control of the overall operation. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.
