A replaceable screen separating refiner

Abstract

This utility model relates to the field of separate refining machines, and more particularly to a separate refining machine with replaceable screens. In the prior art, most separate refining machines use fixed screens. After refining, the screen needs to be disassembled for cleaning, which is time-consuming and labor-intensive, significantly reducing the effective operating time of the equipment and resulting in low production efficiency. A separate refining machine with replaceable screens includes a support frame, etc., with an outer cylinder fixedly connected to the support frame. The outer cylinder has a pulp outlet and a slot. A rotating plate is rotatably connected to the outer cylinder. When replacing the screen frame, rotating and pulling the turntable causes the slider to disengage from the locking block, then the sliding column disengages from the fixing ring, and finally the screen frame is removed from the slide frame. This allows for convenient replacement of the screen frame, thereby improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of separation refiners, and more particularly to a replaceable screen separation refiner. Background Technology

[0002] A separating mill is a mechanical device that integrates grinding and pulp-residue separation functions. Soaked soybeans and other raw materials are fed into the machine along with water. They are ground by a high-speed rotating grinding disc, and the resulting slurry is separated from the residue in real time by passing through a screen.

[0003] In existing technologies, most separate grinding equipment is equipped with a fixed screen design. After grinding is completed, the screen needs to be disassembled for cleaning, which is time-consuming and labor-intensive, and will also significantly reduce the effective operating time of the equipment, resulting in low production efficiency. Utility Model Content

[0004] In view of the shortcomings or defects of the prior art, this utility model provides a replaceable screen separation type pulper, which can conveniently replace the screen frame, thereby improving production efficiency.

[0005] The technical implementation scheme of this utility model is as follows: A replaceable screen separation type pulper includes a support frame, an outer cylinder fixedly connected to the support frame, a pulp outlet on the outer cylinder, a slot on the outer cylinder, a rotating plate rotatably connected to the outer cylinder, a servo motor fixedly connected to the support frame, a feeding cylinder fixedly connected to the outer cylinder, a discharge port on the feeding cylinder, a fixed grinding disc fixedly connected to the feeding cylinder, a conveying rod rotatably connected inside the feeding cylinder, the conveying rod passing through the fixed grinding disc, one end of the conveying rod being fixedly connected to the output shaft of the servo motor, and several grinding strips on the conveying rod. A rotating grinding disc is fixedly connected to the other end of the conveying rod. An auger is fixedly connected to the rotating grinding disc. A slide is placed on the support. A circular groove is opened on the slide. One end of the auger is located in the circular groove on the slide. A slag outlet is provided on the slide. A screen frame is fixedly connected to the slide. One end of the screen frame is located in a slot on the outer cylinder. The fixed grinding disc, the rotating grinding disc, and the auger are all located inside the screen frame. Two locking blocks are fixedly connected to the screen frame. The two locking blocks are symmetrically arranged. Both locking blocks have sliding grooves. A fixing mechanism is provided inside the outer cylinder. A screening mechanism is provided on the screen frame.

[0006] Furthermore, the fixing mechanism includes mounting plates, two of which are fixedly connected to the outer cylinder. The two mounting plates are symmetrically arranged, each with a limit groove. Push rods are slidably connected to each mounting plate, and one end of each push rod is rotatably connected to a turntable. Each turntable has a limit post located within the limit grooves on the two mounting plates. The other end of each push rod is fixedly connected to a push block, each push block having two inclined surfaces. A slider is slidably connected to each push block, and the sliders are respectively engaged in two locking blocks. Compression springs connect each push block to the sliders. Two sliding rods are slidably connected to each slider, with two sliding rods on the same slider forming a group. A telescopic spring connects each slider to the two sliding rods in the same group, and the two groups of sliding rods are located within sliding grooves on the locking blocks.

[0007] Furthermore, the screening mechanism includes a sliding column, which is fixedly connected to the screen frame. A return spring is connected between the sliding column and the screen frame. A fixed ring is fixedly connected to the rotating grinding disc, and a wedge is fixedly connected to the fixed ring. The wedge has an inclined surface, and the fixed ring has a movable groove. The bottom end of the sliding column is located in the movable groove on the fixed ring.

[0008] This invention has the following advantages: When the operator starts the servo motor, the servo motor drives the conveyor rod to initially crush and transport the material. The fixed grinding disc and the rotating grinding disc grind the material, and the screen frame screens the ground material. When the screen frame needs to be replaced, the operator rotates and pulls the turntable to disengage the slider from the locking block. Then, the operator pulls the sliding column to disengage from the fixed ring. Next, the operator pulls the screen frame to disengage from the outer cylinder. Immediately afterward, the operator installs the new screen frame onto the slide frame and re-locks it into the outer cylinder. The sliding column locks into the movable groove on the fixed ring. Then, the operator pushes the two turntables to move closer to each other, and the two sets of sliding rods lock into the sliding grooves on the two locking blocks again. Finally, the operator rotates the two turntables so that the limiting posts on the turntables lock into the limiting grooves on the mounting plate. In this way, the screen frame can be easily replaced, thereby improving production efficiency. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 A replaceable screen separating type pulper, such as Figures 1-8As shown, the device includes a support 1, an outer cylinder 2 fixedly connected to the support 1, a slurry outlet on the outer cylinder 2, a slot on the outer cylinder 2, a rotating plate 3 rotatably connected to the outer cylinder 2, a servo motor 4 fixedly connected to the support 1, a feeding cylinder 5 fixedly connected to the outer cylinder 2, a discharge port on the feeding cylinder 5, a fixed grinding disc 7 fixedly connected to the feeding cylinder 5, a conveying rod 6 rotatably connected inside the feeding cylinder 5, the conveying rod 6 passing through the fixed grinding disc 7, one end of the conveying rod 6 fixedly connected to the output shaft of the servo motor 4, several grinding strips on the conveying rod 6, and a rotating grinding disc 8 fixedly connected to the other end of the conveying rod 6. A screw conveyor 9 is fixedly connected to the moving grinding disc 8. A slide 10 is placed on the support 1. A circular groove is opened on the slide 10. One end of the screw conveyor 9 is located in the circular groove on the slide 10. A slag outlet is provided on the slide 10. A screen frame 11 is connected to the slide 10 by bolts. One end of the screen frame 11 is located in the slot on the outer cylinder 2. The fixed grinding disc 7, the rotating grinding disc 8, and the screw conveyor 9 are all located inside the screen frame 11. Two locking blocks 12 are fixedly connected to the screen frame 11. The two locking blocks 12 are symmetrically arranged. Both locking blocks 12 have sliding grooves. A fixing mechanism is provided inside the outer cylinder 2. A screening mechanism is provided on the screen frame 11.

[0020] The fixing mechanism includes mounting plates 131. Two mounting plates 131 are fixedly connected to the outer cylinder 2. The two mounting plates 131 are symmetrically arranged. Each mounting plate 131 has a limit groove. Push rods 132 are slidably connected to each mounting plate 131. One end of each push rod 132 is rotatably connected to a turntable 133. Each turntable 133 has a limit post, which is located in the limit groove on each mounting plate 131. The other end of each push rod 132 is fixedly connected to a push block 134. Each push block 134 has a... The device has two inclined surfaces. Each of the two push blocks 134 is slidably connected to a slider 135. The two sliders 135 are respectively inserted into the two locking blocks 12. The two push blocks 134 and the two sliders 135 are respectively connected to a compression spring 137 via a hook. Each of the two sliders 135 is slidably connected to two sliding rods 136. The two sliding rods 136 located on the same slider 135 form a group. The slider 135 and the two sliding rods 136 in the same group are connected to a telescopic spring 138 via a hook. The two groups of sliding rods 136 are respectively located in the sliding grooves on the two locking blocks 12.

[0021] The screening mechanism includes a sliding column 141, which is fixedly connected to the screen frame 11. A return spring 142 is connected between the sliding column 141 and the screen frame 11 via a hook. A fixed ring 143 is fixedly connected to the rotating grinding disc 8, and a wedge 144 is fixedly connected to the fixed ring 143. The wedge 144 has an inclined surface, and the fixed ring 143 has a movable groove. The bottom end of the sliding column 141 is located in the movable groove on the fixed ring 143.

[0022] Initially, the limiting post on the turntable 133 is located in the limiting groove on the mounting plate 131. The locking block 12 presses against the slider 135, and the compression spring 137 is in a compressed state. The push block 134 presses against the two sliding rods 136 in the same group, and the telescopic spring 138 is in a compressed state. First, the operator starts the servo motor 4, and then pours the material into the conveying cylinder 5. The servo motor 4 drives the conveying rod 6 to initially crush and transport the material. The initially crushed material is then conveyed between the fixed grinding disc 7 and the rotating grinding disc 8. The rotation of the conveying rod 6 drives the rotating grinding disc 8, the auger 9, the fixed ring 143, and the wedge block 144 to rotate. The fixed grinding disc 7 and the rotating grinding disc 8 grind the material. The ground material falls onto the screen frame 11, and the screen frame 11 grinds the ground material. The material is screened, and the slurry is discharged through the slurry outlet on the outer cylinder 2. The rotating auger 9 transports the material residue, which is discharged through the residue outlet on the slide 10. At the same time, the rotating fixed ring 143 squeezes the sliding column 141 to move horizontally back and forth. The horizontal back and forth movement of the sliding column 141 drives the screen frame 11 and the slide 10 to move horizontally back and forth. When the screen frame 11 needs to be replaced, the operator rotates the two turntables 133. The turntables 133 will disengage from the mounting plate 131, and the compression spring 137 will rebound. The rebound of the compression spring 137 will drive the push block 134, push rod 132, and turntable 133 to move away from the locking block 12. The push block 134 will disengage from the two sliding rods 136 in the same group, and the extension spring 138 will rebound. The rebound of 138 will cause the two sliding rods 136 in the same group to move away from each other, and the sliding rods 136 will disengage from the locking block 12. Then, the operator pulls the turntable 133, causing the slider 135 to disengage from the locking block 12. Next, the operator pulls the sliding column 141 upward, causing the sliding column 141 to disengage from the fixing ring 143. The return spring 142 will be stretched. Then, the operator pulls the screen frame 11, the slide 10, and the sliding column 141 to move horizontally, causing the screen frame 11 to disengage from the outer cylinder 2, and the slide 10 to disengage from the support 1 and the auger 9. The return spring 142 will reset, and the reset of the return spring 142 will cause the sliding column 141 to move downward and reset. Then, the operator separates the screen frame 11 from the slide 10 and installs a new screen. The screen frame 11 is installed onto the slide 10. The slide 10 is then placed back onto the support 1. One end of the new screen frame 11 will re-engage in the slot on the outer cylinder 2. The wedge block 144 will press the slide column 141 upwards again, stretching the return spring 142. When the slide column 141 aligns with the movable slot on the fixing ring 143, the return spring 142 will reset. This reset will cause the slide column 141 to engage in the movable slot on the fixing ring 143. Next, the operator pushes the two turntables 133 closer together, causing the slider 135 to engage in the locking block 12. Then, the compression spring 137 is compressed again, and the push block 134 presses the two slide rods 136 in the same group away from each other, compressing the extension spring 138 again.The two sets of sliding rods 136 will then engage again in the sliding grooves on the two locking blocks 12. Finally, the operator rotates the two turntables 133, causing the limiting posts on the turntables 133 to re-engage in the limiting grooves on the mounting plate 131. This allows for convenient replacement of the screen frame 11, thereby improving production efficiency.
