Description

Technical Field

[0001] The utility model belongs to the technical field of solid waste resin treatment and recovery, and in particular relates to an integrated calcium carbonate solid waste resin treatment and recovery device. Background Art

[0002] Waste solid resin generally refers to solid waste generated during the production process. This waste may come from industries such as plastics, rubber, papermaking, coatings, food, pharmaceuticals, and electronics. This waste solid resin may be generated from defective products, scrap, or expired products during the production process. Calcium carbonate is often added to waste solid resin to modify its properties, increasing its hardness and rigidity.

[0003] Currently, the primary method for disposing of calcium carbonate solid resin waste is landfill. However, the calcium carbonate present in it is difficult to degrade. If left untreated, it can lead to chemical pollution, posing a threat to human health and the ecological environment. Furthermore, the disposal of large quantities of calcium carbonate solid resin waste is a significant waste. With the implementation of national sustainable development policies and growing environmental awareness, calcium carbonate solid resin waste can be pulverized and recycled for use as filler or melted for regeneration. However, there is currently a lack of integrated calcium carbonate solid resin waste treatment and recovery equipment.

[0004] Therefore, an integrated calcium carbonate solid waste resin treatment and recovery equipment is proposed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes an integrated calcium carbonate solid waste resin processing and recycling equipment.

[0006] To achieve the above objectives, the present invention provides an integrated calcium carbonate solid waste resin processing and recycling device, comprising:

[0007] Screw feeder;

[0008] A pulverizing mechanism, wherein the top of the pulverizing mechanism is connected to the discharge end of the screw feeder, and the bottom of the pulverizing mechanism is open and fixedly connected to a primary filter screen;

[0009] The grinding mechanism has an open top and is connected to the bottom of the crushing mechanism, and the bottom of the grinding mechanism is connected to a discharge pipe.

[0010] For large pieces of calcium carbonate solid waste resin, they are first gradually conveyed into the crushing mechanism through a screw feeder, where they are crushed to reduce the particle size of the calcium carbonate solid waste resin. The crushed calcium carbonate solid waste resin is filtered through a primary filter and then falls into the grinding mechanism. Incompletely crushed calcium carbonate solid waste resin cannot pass through the primary filter and continues to be crushed in the crushing mechanism until it can pass through the primary filter. The primary filter ensures the crushing effect of the crushing mechanism. The calcium carbonate solid waste resin that falls into the grinding mechanism is ground in the grinding mechanism, further reducing the particle size of the calcium carbonate solid waste resin. The ground calcium carbonate solid waste resin is discharged from the discharge pipe. The crushing and grinding treatment of calcium carbonate solid waste resin by this equipment improves the fluidity and processing performance of the calcium carbonate solid waste resin, facilitates subsequent melt regeneration, and also makes the calcium carbide more evenly dispersed in the resin, thereby improving product quality.

[0011] Preferably, the crushing mechanism includes a crushing shell, the crushing shell is provided with a crushing inner cavity, the first-level filter is fixedly connected to the bottom of the crushing inner cavity, the top of the crushing shell is fixedly connected to a crushing motor, the output end of the crushing motor is fixedly connected to a crushing shaft, the crushing shaft passes through the crushing inner cavity and is rotatably connected to the crushing shell and the first-level filter; a plurality of crushing cutters are circumferentially fixedly connected to the crushing shaft.

[0012] Resins containing calcium carbonate are relatively brittle and can be cut and crushed by a crushing motor driving a crushing shaft, which in turn drives the crushing blades to rotate.

[0013] Preferably, the grinding mechanism includes a grinding shell, a grinding inner cavity is opened in the grinding shell, the top of the grinding inner cavity is connected to the crushing mechanism, a secondary filter is fixedly connected to the bottom of the grinding inner cavity, a grinding roller is rotatably connected in the grinding inner cavity, a gap is provided between the grinding roller and the grinding shell, a rotating shaft is fixedly connected to the bottom of the grinding roller, and the rotating shaft passes through the secondary filter and is connected to the grinding motor.

[0014] The crushed calcium carbonate solid waste resin falls into the grinding cavity through the first-level filter, is ground and crushed in the gap between the grinding roller and the grinding shell, moves downward while grinding, and finally falls from the second-level filter. The second-level filter intercepts the unqualified calcium carbonate solid waste resin and continues to grind it in the grinding mechanism. The qualified calcium carbonate solid waste resin falls into the transfer barrel, ensuring the grinding effect.

[0015] Preferably, a transfer cylinder is fixedly connected to the bottom of the grinding shell, the top of the transfer cylinder is connected to the grinding inner cavity, and the bottom side is connected to the discharge pipe. The grinding motor is fixed to the bottom surface of the transfer cylinder, and the rotating shaft passes through the transfer cylinder and is transmission-connected to the grinding motor.

[0016] The calcium carbonate solid waste resin powder that falls from the secondary filter is transported to the transfer barrel and then discharged through the discharge pipe; the grinding motor is fixed to the bottom of the transfer barrel, and the transfer barrel provides an installation position for the grinding motor to avoid being installed directly under the secondary filter and affecting filtration.

[0017] Preferably, a first spiral blade is fixedly connected to the outside of the rotating shaft.

[0018] The grinding motor drives the rotating shaft to rotate, which in turn drives the first spiral blade to rotate, so that the spiral blade can transport the calcium carbonate solid waste resin powder falling from the grinding mechanism to the bottom discharge pipe to avoid blockage of the transfer barrel.

[0019] Preferably, the grinding roller is in a frustum shape, and the grinding inner cavity matches the shape of the grinding roller.

[0020] Zhuitaixing's grinding roller is not easy to slide out of the grinding shell, and the gravity of the grinding roller itself can be used to squeeze the calcium carbonate solid waste resin, making the grinding more complete.

[0021] Preferably, a conductive column is fixedly connected to the top of the grinding roller, a second spiral blade is fixedly connected to the outer side of the conductive column, and the top of the second spiral blade is higher than the top surface of the conductive column.

[0022] The second spiral blade can push and transport the calcium carbonate solid waste resin on the top of the grinding roller downward, thereby increasing the tightness of the calcium carbonate solid waste resin between the grinding roller and the grinding shell, making the grinding more complete and efficient.

[0023] Preferably, a conical guide hopper is fixedly connected to the top surface of the conductive column.

[0024] The conical guide hopper can guide the calcium carbonate solid waste resin falling from the crushing mechanism to move into the gap between the grinding roller and the grinding shell to avoid accumulation on the top of the conduction column.

[0025] Compared with the prior art, the present invention has the following advantages and technical effects:

[0026] For large pieces of calcium carbonate solid waste resin, they are first gradually conveyed into the crushing mechanism through a screw feeder, where they are crushed to reduce the particle size of the calcium carbonate solid waste resin. The crushed calcium carbonate solid waste resin is filtered through a primary filter and then falls into the grinding mechanism. Incompletely crushed calcium carbonate solid waste resin cannot pass through the primary filter and continues to be crushed in the crushing mechanism until it can pass through the primary filter. The primary filter ensures the crushing effect of the crushing mechanism. The calcium carbonate solid waste resin that falls into the grinding mechanism is ground in the grinding mechanism, further reducing the particle size of the calcium carbonate solid waste resin. The ground calcium carbonate solid waste resin is discharged from the discharge pipe. The crushing and grinding treatment of calcium carbonate solid waste resin by this equipment improves the fluidity and processing performance of the calcium carbonate solid waste resin, facilitates subsequent melt regeneration, and also makes the calcium carbide more evenly dispersed in the resin, thereby improving product quality.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] Reference Figures 1 to 4 As shown, this embodiment provides an integrated calcium carbonate solid waste resin processing and recovery device, comprising:

[0036] Screw feeder 1;

[0037] The top of the crushing mechanism is connected to the discharge end of the screw feeder 1, and the bottom of the crushing mechanism is open and fixed with a first-level filter screen 2;

[0038] The grinding mechanism has an open top and is connected to the bottom of the crushing mechanism, and a discharge pipe 3 is connected to the bottom of the grinding mechanism.

[0039] For large pieces of calcium carbonate solid waste resin, they are first gradually conveyed into the crushing mechanism through the screw feeder 1, where they are crushed to reduce the particle size of the calcium carbonate solid waste resin. The crushed calcium carbonate solid waste resin is filtered through the primary filter 2 and then falls into the grinding mechanism. Incompletely crushed calcium carbonate solid waste resin cannot pass through the primary filter 2, so it continues to be crushed in the crushing mechanism until the calcium carbonate solid waste resin can pass through the primary filter 2; the primary filter 2 ensures the crushing effect of the crushing mechanism; the calcium carbonate solid waste resin that falls into the grinding mechanism is ground in the grinding mechanism, further reducing the particle size of the calcium carbonate solid waste resin. The ground calcium carbonate solid waste resin is discharged from the discharge pipe 3. The crushing and grinding treatment of the calcium carbonate solid waste resin by this equipment improves the fluidity and processing performance of the calcium carbonate solid waste resin, facilitates subsequent melting and regeneration, and also makes the calcium carbide more evenly dispersed in the resin, thereby improving product quality.

[0040] A further optimized solution is that the crushing mechanism includes a crushing shell 4, the crushing shell 4 is provided with a crushing inner cavity 5, the first-level filter 2 is fixedly connected to the bottom of the crushing inner cavity 5, the top of the crushing shell 4 is fixedly connected to a crushing motor 6, the output end of the crushing motor 6 is fixedly connected to a crushing shaft 7, the crushing shaft 7 passes through the crushing inner cavity 5 and is rotatably connected to the crushing shell 4 and the first-level filter 2; a number of crushing cutters 8 are fixedly connected circumferentially on the crushing shaft 7.

[0043] The crushed calcium carbonate solid waste resin falls into the grinding cavity 10 through the primary filter 2, is ground and crushed in the gap between the grinding roller 12 and the grinding shell 9, moves downward while being ground, and finally falls from the secondary filter 11. The secondary filter 11 intercepts the unqualified calcium carbonate solid waste resin and continues to grind it in the grinding mechanism. The qualified calcium carbonate solid waste resin falls into the transfer barrel 15, ensuring the grinding effect.

[0044] To further optimize the solution, a transfer cylinder 15 is fixedly connected to the bottom of the grinding shell 9, the top of the transfer cylinder 15 is connected to the grinding inner cavity 10, and the bottom side is connected to the discharge pipe 3.

[0046] According to a further optimized solution, a first spiral blade 16 is fixedly connected to the outside of the rotating shaft 13 .

[0047] The grinding motor 14 drives the rotating shaft 13 to rotate, and then drives the first spiral blade 16 to rotate, so that the spiral blade can transport the calcium carbonate solid waste resin powder falling from the grinding mechanism to the bottom discharge pipe 3 to avoid clogging of the transfer cylinder 15.

[0048] According to a further optimized solution, the grinding roller 12 is in a frustum shape, and the grinding inner cavity 10 matches the shape of the grinding roller 12 .

[0049] The grinding roller 12 of Zhuitaixing is not easy to slide out of the grinding shell 9, and the calcium carbonate solid waste resin can be squeezed by the gravity of the grinding roller 12 itself, so that the grinding is more complete.

[0051] The second spiral blade 18 can push and transport the calcium carbonate solid waste resin on the top of the grinding roller 12 downward, thereby increasing the tightness of the calcium carbonate solid waste resin between the grinding roller 12 and the grinding shell 9, making the grinding more complete and efficient.

[0052] To further optimize the solution, a conical guide hopper 19 is fixedly connected to the top surface of the conductive column 17.
