Description

Technical Field

[0001] This utility model relates to the technical field of spiral dewatering equipment, specifically to the discharge adjustment mechanism of a spiral dewatering machine. Background Technology

[0002] Spiral dewatering machines are widely used in sludge treatment, food processing, and chemical raw material dewatering. The adjustment mechanism at the discharge end directly affects the dewatering efficiency, material dryness, and equipment operational stability. Currently, the discharge adjustment methods for spiral dewatering machines mainly include manual baffle adjustment and cylinder-driven baffle adjustment.

[0003] In related technologies, a search revealed a screw dewatering machine with a dewatering adjustment device, as described in patent number CN203893622U. This dewatering machine has an adjustment plate at the outlet of the screw drum, threaded onto the screw shaft extending from the outlet. Although the position of the adjustment plate can be manually adjusted, once fixed, the plate cannot be moved during dewatering, thus affecting dewatering efficiency. Furthermore, when hard impurities are mixed into the material, the plate is prone to deformation or damage to the drive mechanism, resulting in high equipment maintenance costs. To address these issues, a screw dewatering machine discharge adjustment mechanism is proposed. Utility Model Content

[0004] In view of this, the present invention provides a discharge adjustment mechanism for a spiral dewatering machine. The present invention uses an electric motor to drive a lead screw to rotate, thereby moving and adjusting two sliding seats, which in turn allows the baffle to be adjusted back and forth, thus controlling the distance between the baffle and the discharge outlet. A locking mechanism limits the sliding seats after they stop moving. A spring rod can automatically adjust the distance between the baffles according to the amount and hardness of the material, maintaining a stable dewatering pressure. When there are foreign objects, the elastic yield provided by the spring rod can prevent the equipment from being overloaded and damaged, thereby improving the service life of the components.

[0005] To solve the above-mentioned technical problems, this utility model provides a discharge adjustment mechanism for a spiral dewatering machine, including a spiral shaft rotatably disposed inside the spiral dewatering machine, spiral blades of decreasing size disposed on the surface of the spiral shaft, a bearing seat rotatably disposed at the discharge end of the spiral shaft, a discharge channel disposed on the surface of the spiral blades, a sealing plate disposed on the surface of the discharge end of the discharge channel, a baffle disposed at the discharge port of the discharge channel, extension plates disposed on the left and right sides of the baffle, a connecting sleeve disposed in the middle of each extension plate, a lead screw disposed in each connecting sleeve, a motor disposed at the end of each lead screw away from the discharge channel, a sliding seat slidably disposed in the middle of each lead screw, a linkage component disposed on each sliding seat, a guide component disposed on the upper part of each linkage component, and a linkage rod disposed between two linkage components.

[0006] A locking mechanism is provided at the connection between the motor output end and the lead screw. The locking mechanism is used to position the sliding seat and prevent the sliding seat from moving in the opposite direction due to the reverse pressure of the baffle. A limit key is provided on the locking mechanism to position the lead screw after it stops.

[0007] A positioning seat is provided at the end of the lead screw away from the motor. The positioning seat is used to fix the other end of the lead screw, so that the lead screw crossarm is between the sealing plate and the motor, and the positioning seat is fixed on the sealing plate.

[0008] The linkage assembly includes a linkage block on the top of the sliding seat, which connects the sliding seat to the extension rod. The linkage block is in the shape of an inverted U-shape, and an extension rod is provided on the top of the linkage block. The extension rod connects the linkage block to the guide assembly, thereby linking the two guide assemblies together.

[0009] The guide assembly includes a protrusion connected to the top of the extension rod. The protrusion is used to connect both the main threaded rod and the auxiliary threaded rod to the extension rod. The protrusion is inverted, and the main threaded rod is movably mounted in the middle of the protrusion. The main threaded rod is used to stabilize the sliding seat along the linear movement. An auxiliary threaded rod is provided on each of the left and right sides of the protrusion. The auxiliary threaded rod is used to assist the main threaded rod in stabilizing the linear movement of the sliding seat on the screw without deviation. The auxiliary threaded rod is threadedly connected to the protrusion. A guide block is provided at the front and rear ends of the main threaded rod and the auxiliary threaded rod, respectively. The guide blocks are used to fix the ends of the main threaded rod and the auxiliary threaded rod.

[0010] A spring rod is installed at each of the four corners of the sliding seat near the baffle. The spring rod is used to follow the movement of the spring and also to automatically adjust the counter-impact force on the baffle. When the material is pushed to the discharge port by the screw shaft, the spring rod can automatically adjust the position of the baffle according to the amount and hardness of the material to maintain a stable dewatering pressure. In case of material blockage or abnormality, the elastic yield provided by the spring rod can prevent the equipment from being overloaded and damaged. The other end of each spring rod is fixed to the baffle by a connecting block.

[0011] A reinforcing rod is fixedly installed between the bottoms of the two sliding seats.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The electric drive screw rotates to move and adjust the two sliding seats, which in turn allows the baffle to be adjusted back and forth, thus controlling the distance between the baffle and the discharge outlet. A locking mechanism limits the sliding seats after they stop moving. A spring rod can automatically adjust the distance between the baffles according to the amount and hardness of the material to maintain stable dewatering pressure. When there are foreign objects, the elastic yield provided by the spring rod can prevent the equipment from being overloaded and damaged, thereby improving the service life of the components.

The directional block is used to fix the ends of the main thread rod and the auxiliary thread rod. Attached Figure Description

This controls the distance between the baffle 200 and the outlet of the discharge channel 104. After the initial position of the baffle 200 is set, the locking mechanism 204 positions the stopped sliding seat 300 to prevent the baffle 200 from being pushed back towards the motor 301 by the back force of the discharge end. The spring rod 302 is connected to the baffle 200, allowing elastic adjustment between the baffle 200 and the sliding seat 300.
