[0002] A horizontal screw centrifuge is a device that uses the principle of centrifugal sedimentation to separate solids and liquids. It mainly consists of core components such as a rotating drum, screw conveyor, differential gear, and control system. It achieves efficient separation of solids and liquids in materials through centrifugal force generated by high-speed rotation. It can be widely used in various industrial separation fields, the extraction and production of various oils and greases, and various processes in chemical, food, light industry, papermaking, and mining industries.

[0003] A search revealed Chinese patent application number 201810811540.6, which discloses a horizontal screw centrifuge, including a drum, a screw conveyor, a main motor, and an auxiliary motor. The drum comprises a cylindrical section and a conical dewatering section. The screw conveyor includes a conical section, a feed hopper, and a cylindrical section arranged sequentially. The feed hopper has a discharge port and a sealed feed pipe. The conical section of the drum has a slag discharge port at its small-diameter end. The cylindrical section of the drum has an end ring at its end away from the conical section, forming a liquid outlet between the end ring and the cylindrical section. The end ring and the drum together form a separation liquid pool. The feed pipe includes an outer pipe that is rotatably and sealed to the feed hopper and an inner pipe that is detachably connected inside the outer pipe. The horizontal screw centrifuge in the aforementioned patent has the following drawback: during the material separation process, solid materials can easily clog the discharge port, thus affecting the continuous separation of the centrifuge.

Detailed Implementation

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The centrifugal structure of a horizontal screw centrifuge, such as Figures 1-5As shown, the centrifuge includes a centrifuge body 1, which is equipped with a detachable cover. Support legs 2 are symmetrically installed at the bottom of the centrifuge body 1. A drive mechanism 5 is installed on one side of the centrifuge body 1 via a support plate 4. A discharge port 9 is provided at the bottom of the centrifuge body 1 near the drive mechanism 5, and a discharge port 10 is provided at the bottom of the centrifuge body 1 away from the drive mechanism 5. A rotating drum 6 and a pushing mechanism are rotatably installed inside the centrifuge body 1 via bearing seats. The centrifuge also includes an anti-clogging mechanism. The rotating drum 6 is a cylindrical structure composed of a cylinder and a cone. Solid discharge chambers 7 are arranged circumferentially on the conical cylindrical structure, and liquid discharge chambers 8 are arranged circumferentially at the end of the cylindrical structure.

[0026] By using the drive mechanism 5 to drive the drum 6 and the pusher mechanism to rotate, the material is separated into solids. By using the anti-clogging mechanism, the material is prevented from clogging during feeding and discharging, thus ensuring the continuity of production.

[0027] The feeding mechanism includes a first mandrel 11 and a second mandrel 13. The first mandrel 11 and the second mandrel 13 are fixed at their ends by an annular connecting plate. The connecting plate is arc-shaped to fit the outer diameter of the mandrel. A sealing ring is provided on the mating end face of the two mandrels. An installation groove is provided in the end of the first mandrel 11 near the second mandrel 13. A cover plate 17 is detachably installed at the end of the groove. The second mandrel 13 is a hollow structure. A feed port is symmetrically provided at the end of the second mandrel 13 near the first mandrel 11. A feed pipe 18 is provided at the other end of the second mandrel 13.

[0028] The anti-clogging mechanism includes an electric push rod 12, which is installed in a mounting groove at the end of the first mandrel 11. A push rod 15 is detachably mounted on the output end of the electric push rod 12, and the push rod 15 is located in the slotted hole of the second mandrel 13. The electric push rod 12 is waterproofed. By using the electric push rod 12 to move the push rod 15, material blockage can be avoided without affecting the material conveying process.

[0029] This device is further configured such as Figure 4 As shown, a helical blade 14 is provided on the mandrel 11. The helical blade 14 adopts a variable pitch structure. The pitch of the helical blade 14 gradually decreases from one end near the mandrel 13 to the other end. A helical blade 16 is welded and installed on the surface of the mandrel 13. The helical blade 16 adopts a constant pitch width.

[0030] The ends of the spiral blades 16 and 14 that are in contact with the drum 6 are provided with elastic scrapers. The size of the elastic scrapers is adjusted according to the actual product. The elastic scrapers can clean the wall-adhered substances, thereby reducing the material residue on the inner wall of the drum 6.

[0031] This device is further configured such as Figure 1 As shown, the drive mechanism 5 is driven by two motors. These two motors, via a differential, drive the drum 6 and the pushing mechanism to rotate in the same direction at different speeds. The connection method and circuit control technology between the drive mechanism 5 and the spindle 11 and the drum 6 are existing technologies and will not be elaborated here. By driving the drum 6, spindle 11, and spindle 2 13 to rotate, solid materials are separated from liquids through differential speed in the same direction. The solid material is discharged through the solid discharge chamber 7 and then through discharge port 9, while the liquid is discharged through the liquid discharge chamber 8 and then through discharge port 2 10.

[0032] This device is further configured such as Figure 1 , Figure 3 , Figure 5 As shown, the anti-clogging mechanism also includes a vibration motor 3. The vibration motor 3 is installed on the outer wall of the centrifuge body 1 near the discharge port 9. A vibration rod 19 is installed inside the discharge port 9 via a mounting plate 20. The mounting plate 20 and the vibration rod 19 are connected by a hinge. The output end of the vibration motor 3 is connected to the vibration rod 19 via a connecting plate. By driving the vibration motor 3, the vibration rod is driven to reciprocate laterally along the discharge port 9, thereby discharging the blocked material from the discharge port 9 and preventing blockage.

[0033] The circuit connection between the control module and the individual components adopts existing technical solutions. The parts not involved in this device are the same as or can be implemented using existing technologies.

[0034] Working principle: The drive mechanism 5 drives the drum 6 and the pushing mechanism to rotate. The material is fed into the mandrel 13 through the feed pipe 18 by the feeder. The material enters the inner wall of the drum 6 through the feed port of the mandrel 13. Due to the differential rotation between the pushing mechanism and the drum 6, materials of different particle sizes and densities settle at different speeds under the action of centrifugal force. The larger particles and densities will settle to the inner wall of the drum 6 first, while the smaller particles and densities will remain in the upper liquid phase. As the centrifugal force gradually increases, the graded separation of materials of different particle sizes is achieved. After sufficient separation, the solid material enters the discharge port 9 through the solid discharge chamber 7, and the liquid material enters the discharge port 10 through the liquid discharge chamber 8 to achieve solid-liquid separation. During the separation process, the electric push rod 12 drives the push rod 15 to move at regular intervals to prevent the incoming material from clogging. The vibration motor 3 drives the vibration rod 19 to vibrate the solid material in the discharge port 9 to avoid clogging.

However, the protection scope of the present utility model is not limited thereto.
