Description

Technical Field

[0001] This invention belongs to the field of rosin purification technology, and more specifically, relates to a rosin purification and recovery device. Background Technology

[0002] Pine resin is a natural resin extracted from coniferous trees such as pine, possessing excellent viscosity, heat resistance, and chemical stability. It is widely used in various fields including chemicals, coatings, pharmaceuticals, and fragrances. However, pine resin directly collected from nature usually contains a certain amount of impurities, such as sawdust, branches, and moisture. These impurities not only affect the quality of the pine resin but may also adversely impact subsequent processing techniques.

[0003] Therefore, it is necessary to purify and recycle rosin. Currently, the most convenient and quick method is to dilute the rosin with water to improve its fluidity, and then separate the solid impurities from the liquid obtained after the unpurified rosin is mixed and melted with water. After separating the solids, the liquid is then distilled to remove excess water to obtain purified rosin.

[0004] When separating solid impurities from liquids, the traditional method is manual filtration using a strainer, which is not only cumbersome but also inefficient. Existing technologies use specialized filtration equipment, such as patent publication number CN105582718B, which discloses a multi-stage dry melting resin filter. This filter uses a rotating stainless steel wire brush to clean the impurities left on the filter plate when separating solid impurities. Although the rotating stainless steel wire brush can clean impurities, the characteristics of some liquids cause them to adhere to the surface of the impurities and be carried away, resulting in poor separation effect.

[0005] In view of the shortcomings of the prior art, a recovery device for rosin purification is designed to overcome the shortcomings of the prior art, which can effectively separate solid impurities from liquids and shake off the residual liquid attached to the solid impurities. Summary of the Invention

[0010] Preferably, the recycling module further includes a feeding plate that slides on the feeding port of the feeding frame. The left end of the feeding plate is connected to the front and rear sides of the feeding plate. A bracket located between the lower part of the feeding plate and the upper part of the turntable is connected to one side of the processing frame. A rotating cylinder rotates on the bracket. A torsion spring is connected between the rotating cylinder and the bracket and surrounds the bracket. The torsion spring is used to reset the rotating cylinder. Two swing frames are connected to the upper side of the rotating cylinder and surround the front and rear driving shafts respectively. The strip grooves on the swing frames surround the driving shafts. The lower side of the rotating cylinder has a protruding abutment part that contacts and engages with the left side of the uppermost turntable.

[0011] Preferably, the recycling module further includes a cleaning brush holder that slides on the processing frame, the cleaning brush holder is in contact with the lower side of the arc-shaped filter plate, a rack is connected to the cleaning brush holder, a gear that meshes with the rack is rotated on the processing frame, and a rack is connected to the arc-shaped filter plate that meshes with the gear.

[0012] Preferably, it further includes a connector 1 connecting the arc-shaped filter plate and the rack 2.

[0014] Preferably, it also includes a feeding hopper connected to the upper side of the frame, and the frame has multiple recycling modules arranged from front to back, with the feeding hopper connected to the feeding ports of the feeding frames in the multiple recycling modules.

[0015] Preferably, it also includes a cleaning frame that rotates on the feed hopper. The cleaning frame is located above the feed frame and has multiple L-shaped rods arranged on it.

[0020] 4. When the arc-shaped filter plate moves to the right, it will drive rack two to move to the right and mesh with the gear.

Therefore, they should not be construed as limitations on this invention.

[0036] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will now be clearly and completely described in conjunction with the accompanying drawings. It should be understood that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] A recovery device for pine resin purification, such as Figures 1-4As shown, the system includes a frame 1 and a recovery module tilted on the frame 1. The recovery module is used to separate solid impurities from the liquid obtained after heating an unpurified rosin mixed with water. The recovery module includes a feed frame 11 tilted downwards to the left and a processing frame 12 connected to the lower side of the feed frame 11. The feed inlet of the feed frame 11 is located at the lower end of the feed frame 11. The liquid enters the processing frame 12 from the feed inlet of the feed frame 11 for solid impurity separation. The processing frame 12 has an arc-shaped filter plate 21 for filtering solid impurities inside. The processing frame 12 has an outlet at the bottom. The bottom of the processing frame 12 is composed of a guide plate 121 that tilts downwards and extends to its outlet. The liquid entering the processing frame 12 will pass through the filter plate 21. The liquid continues to fall through the hole and eventually exits from the outlet. Solid impurities in the liquid remain on the arc-shaped filter plate 21. A discharge frame 13, located away from the inlet of the feed frame 11, is connected to one side of the processing frame 12. A connecting port to the discharge frame 13 is opened on the right side of the processing frame 12. A spiral auger 22, located inside the arc-shaped filter plate 21, rotates between the discharge frame 13 and the feed frame 11. Driven by a rotary drive unit located on the discharge frame 13, the spiral auger 22 continuously transports the solid impurities retained on the arc-shaped filter plate 21 to a higher position to the right. During the transport of solid impurities, gravity also allows the liquid adhering to the solid impurities to continuously fall off, ensuring the separation effect. The spiral auger 22... One end of the blade passes through the communication port of the processing frame 12 and extends into the interior of the discharge frame 13. Solid impurities are eventually conveyed to the interior of the discharge frame 13 by the auger 22. The lower part of the discharge frame 13 has a discharge port for discharging solid impurities. The left and right ends of the arc-shaped filter plate 21 slide through the left and right sides of the processing frame 12, respectively. The first end of the arc-shaped filter plate 21 is connected to the transmission frame 23. The transmission frame 23 drives the arc-shaped filter plate 21 to move back and forth along the auger 22, thereby ensuring the normal conveying of the auger 22 and adding the function of shaking the solid impurities on the arc-shaped filter plate 21, thereby further improving the separation effect of the liquid attached to the solid impurities. There are two left and right opposing rollers rotating on the transmission frame 23. The auger 22 The left end is connected to a turntable 24 inclined to the auger 22. The edge of the turntable 24 is located between two rollers on the transmission frame 23. The rotating auger 22 will drive the inclined turntable 24 to rotate. When the turntable 24 squeezes the left roller, the roller will drive the arc-shaped filter plate 21 to move to the left through the transmission frame 23. When the turntable 24 squeezes the right roller, the arc-shaped filter plate 21 will move to the right. In this way, the auger 22 automatically and synchronously drives the arc-shaped filter plate 21 to shake left and right when conveying solid impurities, so as to shake off the liquid attached to the solid impurities during the conveying process and prevent the residual liquid from being carried away by the solid impurities. However, during this process, the filter holes on the arc-shaped filter plate 21 are always located inside the processing frame 12 to prevent the liquid from leaking out of the processing frame 12.

[0038] like Figure 4 As shown, the recycling module includes multiple arc-shaped filter plates 21 and spiral augers 22 stacked from top to bottom in a one-to-one correspondence. The diameter of the filter holes on the multiple arc-shaped filter plates 21 decreases from top to bottom, thereby filtering solid impurities from large to small multiple times during the liquid drop process. The pitch of the spiral blades on the multiple spiral augers 22 decreases from top to bottom, thereby adapting to the different sizes of solid impurities when filtering them. The spiral augers 22 with larger spiral blade pitches transport larger solid impurities, while the spiral augers 22 with smaller spiral blade pitches transport smaller solid impurities, improving the purification effect during recycling. Among the multiple spiral augers 22, except for the topmost spiral auger 22, each of the other spiral augers 22 has a baffle 25 above it to block... Plate 25 is connected to the side of the processing frame 12 near the discharge frame 13. Therefore, during the process of conveying solid impurities by the screw conveyor 22, some liquid that is close to the discharge frame 13 and passes through the arc-shaped filter plate 21 will be caught by the baffle 25 and guided to the lower left of the next arc-shaped filter plate 21, and then conveyed to the upper right by the next screw conveyor 22. This increases the filtration path of the impurities in the liquid and fully separates them. Among the multiple screw conveyors 22, except for the uppermost screw conveyor 22, the other screw conveyors 22 are equipped with a baffle 14. The right side of the baffle 14 is inclined downward. The baffle 14 is connected to the inner side of the discharge frame 13. The baffle 14 is used to guide the falling solid impurities and ensure that the impurities fall from the discharge port of the discharge frame 13.

[0039] like Figure 2 and Figure 4 As shown, the rotary drive assembly includes a servo motor 41 mounted on the right side of the discharge frame 13. The output shaft of the servo motor 41 is connected to the right end of one of the multiple spiral augers 22. The servo motor 41 controls the spiral auger 22 connected to it to rotate and transport solid impurities. Two adjacent spiral augers 22 are driven by a synchronous belt assembly 42, so that when one spiral auger 22 rotates, it can synchronously drive all the other spiral augers 22 to rotate.

[0040] like Figure 4 and Figure 5As shown, the recycling module also includes a discharge plate 31 that slides on the feed inlet of the feed frame 11. Drive shafts 311 are connected to both the front and rear sides of the left end of the discharge plate 31. The drive shafts 311 drive the discharge plate 31 to move left and right relative to the feed inlet of the feed frame 11 to control the flow of liquid. When the discharge plate 31 moves to the right, the feed inlet of the feed frame 11 is blocked; when the discharge plate 31 moves to the left, the feed inlet of the feed frame 11 is not blocked. A positioning device is connected to one side of the processing frame 12. A bracket 32 ​​is located between the bottom of the feed plate 31 and the top of the turntable 24. A rotating cylinder 33 rotates on the bracket 32. A torsion spring 34 is connected between the rotating cylinder 33 and the bracket 32 ​​and surrounds the bracket 32. The torsion spring 34 is used to reset the rotating cylinder 33. Two swing frames 35 are connected to the upper side of the rotating cylinder 33 and surround the front and rear drive shafts 311 respectively. The strip grooves on the swing frames 35 surround the drive shafts 311. The rotation of the rotating cylinder 33 will cause the swing frames 35 to swing. The extrusion drive shaft 311 drives the material feed plate 31 to move. When the swing frame 35 swings to the right, it will squeeze the drive shaft 311, causing the material feed plate 31 to move to the right and block the feed inlet of the feed frame 11. When the swing frame 35 swings to the left, the material feed plate 31 moves to the left and releases the feed inlet of the feed frame 11. The lower side of the rotating drum 33 has a protruding abutment part 36 that contacts and cooperates with the left side of the uppermost turntable 24. When the auger 22 rotates and conveys solid impurities, the rotation of the tilted turntable 24 will gradually squeeze the abutment part 36 to the left. When the contact part 36 moves, the rotating drum 33 will drive the swing frame 35 to swing to the right. Then, as the turntable 24 continues to rotate, the contact part 36 will gradually be released. Under the action of the torsion spring 34, the rotating drum 33 will drive the swing frame 35 to swing to the left, and the rotating drum 33 will drive the contact part 36 to reset. In this way, the power of the screw conveyor 22 to transport solid impurities will automatically and synchronously drive the feeding plate 31 to open and close repeatedly, thereby realizing intermittent feeding and avoiding the phenomenon of blockage caused by too much feeding at the same time.

[0041] like Figure 2 , Figure 6 and Figure 7 As shown, the recycling module also includes a cleaning brush holder 51 that slides on the processing frame 12. The cleaning brush holder 51 contacts and engages with the lower side of the arc-shaped filter plate 21. The cleaning brush holder 51 scrapes and cleans the lower side of the moving arc-shaped filter plate 21 to prevent the filter holes on the arc-shaped filter plate 21 from being blocked by solid impurities. A rack 52 is connected to the cleaning brush holder 51. A gear 53 that meshes with the rack 52 rotates on the processing frame 12. A rack 54 that meshes with the gear 53 is connected to the arc-shaped filter plate 21. When the arc-shaped filter plate 21 moves to the right, it will drive the rack 54 to move to the right and mesh with the gear 53. The gear 53 will drive the cleaning brush holder 51 to move to the left through meshing with the rack 52, so that the cleaning brush holder 51 and the arc-shaped filter plate 21 move towards each other, thereby improving the anti-clogging effect when separating solid impurities.

[0042] like Figure 6 and Figure 8As shown, it also includes a connector 1 connecting the arc-shaped filter plate 21 and the rack 2 54. The connector 1 includes: a guide groove 1 on the processing frame 12, and a sealing strip 211 connected to the arc-shaped filter plate 21 to block the guide groove 1. The sealing strip 211 is used to prevent liquid from leaking out of the guide groove 1 of the processing frame 12. A slider 212 that slides in the guide groove 1 is connected between the sealing strip 211 and the rack 2 54. The moving arc-shaped filter plate 21 will drive the slider 212 to move along the guide groove 1 through the sealing strip 211. The moving slider 212 will also drive the rack 2 54 to move.

[0043] like Figure 6 and Figure 9 As shown, it also includes a second connector connecting the cleaning brush holder 51 and the rack 52. The second connector includes: a guide groove 2 on the treatment frame 12, and a sealing strip 2 511 connected to the arc-shaped filter plate 21 to block the guide groove 2. The sealing strip 2 511 is used to prevent liquid from leaking out of the guide groove 2 of the treatment frame 12. A slider 2 512 that slides in the guide groove 2 is connected between the sealing strip 2 511 and the rack 52. The moving rack 52 will drive the slider 2 512 to move along the guide groove 2. The moving slider 2 512 will also drive the cleaning brush holder 51 to move through the sealing strip 2 511.

[0044] like Figure 1 and Figure 10 As shown, it also includes a feed hopper 61 connected to the upper side of the frame 1. The frame 1 has multiple recycling modules arranged from front to back. The multiple recycling modules greatly improve the working efficiency of liquid and solid separation. The feed hopper 61 is connected to the feed inlet of the feed frame 11 in the multiple recycling modules. Therefore, it is only necessary to pour the liquid into the feed hopper 61 to simultaneously feed it into the multiple processing frames 12 through the feed frame 11, which is convenient to operate.

[0045] like Figure 1 and Figure 10As shown, it also includes a cleaning frame 63 that rotates on the feed hopper 61. The cleaning frame 63 is located above the feed frame 11. Multiple L-shaped rods 631 are arranged on the cleaning frame 63. The counterclockwise rotation of the cleaning frame 63 will cause the L-shaped rods 631 to rotate, pushing the longer solid impurities in the liquid near the feed frame 11 on the cleaning hopper upwards. A collection frame 64 located above the feed frame 11 is connected to the upper side of the feed hopper 61. The side of the collection frame 64 away from the L-shaped rods 631 is inclined downwards. The side of the collection frame 64 near the L-shaped rods 631 has a notch for the L-shaped rods 631 to pass through. The L-shaped rods 631 on the right side of the cleaning frame 63 will push the impurities upwards. As the cleaning frame 63 gradually rotates, the impurities that are lifted up will fall onto the upper side of the L-shaped rod 631 located on the left side of the cleaning frame 63 under the action of gravity. Then, the L-shaped rod 631 on the left side of the cleaning frame 63 continues to rotate and will pass through the notch on the collection frame 64. At this time, the collection frame 64 will intercept the impurities on the upper side of the L-shaped rod 631 and guide them to the lower left, so as to facilitate the centralized processing of longer solid impurities and save the operator from the tedious preliminary retrieval steps. A drive motor 62 is installed on the feed hopper 61. The output shaft of the drive motor 62 is connected to the cleaning frame 63, and the drive motor 62 controls the cleaning frame 63 to rotate slowly.

[0046] like Figure 11 and Figure 12 As shown, it also includes an inverted cone-shaped discharge hopper 1 71 and an inverted cone-shaped discharge hopper 2 72. The discharge ports at the bottom of the discharge frames 13 in the multiple recycling modules are connected to the discharge hopper 1 71. In this way, the solid impurities separated from the multiple recycling modules will be discharged into the discharge hopper 1 71 through the multiple discharge frames 13. The lower part of the discharge hopper 1 71 has a channel 1 for centralized discharge of all solid impurities. The solid impurities can be collected by placing an external container under the channel 11. The lower part of the processing frames 12 in the multiple recycling modules is connected to the discharge hopper 2 72. In this way, the liquid separated from the multiple recycling modules will be discharged into the discharge hopper 2 72 through the multiple processing frames 12. The lower part of the discharge hopper 2 72 has a channel 2 for centralized discharge of all solid impurities.
