Description

Technical Field

[0001] This utility model belongs to the technical field of hanging bag centrifuges, and in particular relates to an explosion-proof flat hanging bag centrifuge. Background Technology

[0002] A hanging bag centrifuge is an intermittent operation device consisting of a drive unit, machine body, casing, drum, hanging bags, braking device, clutch, and other components. It is a closed filtration device for unloading materials from a different location using hanging bags. The material is added to the drum from the top, and under the action of centrifugal force, the liquid phase passes through the filter medium and is discharged outside the machine, while the solid phase is retained inside the drum. A search revealed that patent application number 202022600107.3 discloses an explosion-proof flatbed hanging bag centrifuge, including a base, an outer shell mounted on the base, a rotating drum inside the outer shell, a fixed seat at the lower middle position of the rotating drum, and an installation assembly between the rotating drum and the base. The installation assembly includes a motor, springs, a slide, a rotating rod, a retaining seat, a rotating roller, and a fixing box. The motor is located at the lower end of the base corresponding to the fixed seat. A rotating rod is mounted on the base at the output end of the motor, and a retaining seat is mounted on the other end of the rotating rod. Fixing boxes are mounted on the bases on both sides of the rotating rod. A slide is located inside the fixing box, and a rotating roller is mounted on the side of the slide near the rotating drum. Several springs are arranged between the lower end of the slide and the fixing box.

[0003] However, during actual use, the applicant found that when the drum rotates at high speed driven by the motor, the drum is prone to separating from the card holder due to the lack of a vertical limiting structure. In view of this, we propose an explosion-proof flat plate hanging bag centrifuge. Utility Model Content

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.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:

[0022] An explosion-proof flat-plate hanging bag centrifuge includes a base 1, a cylinder 2 fixedly connected to the top of the base 1, a rotating drum 3 inside the cylinder 2, and through holes 31 evenly distributed on the circumferential sidewall of the rotating drum 3. A motor 6 is fixedly mounted at the bottom of the base 1, and the output end of the motor 6 extends into the cylinder 2 and is fitted with a retainer 8. The retainer 8 is engaged in a groove 32 at the bottom of the rotating drum 3. A stepped ring 4 is held in the cylinder 2 above the rotating drum 3. A stepped groove 23 is formed at the top of the cylinder 2, and the stepped ring 4 is engaged in the stepped groove 23. The stepped ring 4 is pressed into the stepped groove 23 by a cylinder cover 21. A pressure roller 41 is rotatably arranged at the bottom of the stepped ring 4. Several pressure rollers 41 at the bottom of the stepped ring 4 are arranged in a circular array. The pressure rollers 41 rotate along... The top of the drum 3 rolls, allowing the drum 3 to rotate smoothly. The stepped ring 4 and pressure roller 41 can vertically limit the drum 3 after the cover 21 is closed, preventing the drum 3 from separating from the seat 8 during rotation. The cover 21 is hinged to the cylinder 2. Hand grooves 33 are symmetrically opened on the inner side wall of the upper part of the drum 3. The hand grooves 33 make it easy for personnel to remove the drum 3 from the inside of the cylinder 2. The top of the cover 21 is fixedly connected to the feed pipe 211. The bottom of the cylinder 2 is fixedly connected to the drain pipe 22. The lower end of the drain pipe 22 passes through the base 1 and is fitted with a solenoid valve 7. Support legs 11 are fixedly installed at the four corners of the bottom of the base 1.

[0023] A support ring 9 is fixedly connected to the inner wall of the upper part of the cylinder 2. Support balls 91 are provided on the inner wall of the support ring 9. Several support balls 91 are arranged in a ring array on the inner wall of the support ring 9, and the position of the support balls 91 is higher than the uppermost through hole 31. The support balls 91 roll along the outer wall of the drum 3. Through the support ring 9 and the support balls 91, the side wall of the drum 3 can be supported, so that the drum 3 can be more stable during rotation.

[0024] Working principle: In use, the material to be centrifuged can be added into the drum 3 inside the cylinder 2 through the feed pipe 211, and the motor 6 is driven to rotate by the controller 5. The rotation of the motor 6 drives the clamping seat 8 to rotate, which in turn drives the drum 3 to rotate. The rotation of the drum 3 centrifuges the material inside, so that the solid phase remains in the drum 3, while the liquid phase is thrown out from the through hole 31 into the interior of the cylinder 2 and can be discharged through the drain pipe 22. During the rotation of the drum 3, the pressure roller 41 can move along the drum 3. The top rolls and can vertically limit the drum 3 through the step ring 4 and pressure roller 41 to prevent the drum 3 from separating from the holder 8. The support ball 91 can roll along the outer wall of the drum 3 and can support the side wall of the drum 3 through the support ring 9 and support ball 91, so that the drum 3 can rotate smoothly. After centrifugation is completed, open the cylinder cover 21 and take out the step ring 4. Then, manually fasten the hand groove 33 to remove the drum 3 from the inside of the cylinder 2, and then clean out the solid material inside the drum 3.
