Description

Technical Field

[0001] The present application relates to the technical field of silos, and in particular to a plastic finished product recycling silo. Background Art

[0002] The recycling silo for finished plastic products is mainly due to the modern industry's emphasis on efficient resource utilization and environmental protection. With the rapid development of the plastics industry, finished plastic products are increasingly used in all walks of life. The recycling silo technology for finished plastic products realizes the centralized storage, classification and recycling of finished plastic products by designing a special silo system. The silo is usually equipped with an automated control system and sensors that can monitor the storage conditions inside the silo in real time and automatically adjust the conveying speed and quantity of finished plastic products according to production needs. In addition, the silo also needs a sealed design to prevent the finished plastic products from being contaminated or damaged during storage.

[0003] As attached Figure 1 As shown, the relevant circulating silo includes a vertically arranged silo body 1, a feed pipe 2 is installed on the upper side of the silo body 1, a discharge pipe 3 is installed through the lower side of the silo body 1, a knife valve 31 is installed at the discharge pipe 3, an external circulation pipe 6 is also installed through the silo body 1, an external circulation fan 61 is installed on the external circulation pipe 6, one end of the external circulation pipe 6 is connected to the upper surface of the silo body 1, and the other end is connected to the side wall of the discharge pipe 3, the knife valve 31 controls the material discharge and the external circulation fan 61 to transport the fan wind force into the silo body 1.

[0004] The current circulating silo only uses the fan to dry or heat the internal materials. Therefore, it is impossible to uniformly control the heating or cooling of the materials inside the silo. It can only rely on natural diffusion in the silo, which reduces production efficiency. Utility Model Content

[0005] In order to facilitate the control of the heating or cooling of materials inside the silo and improve production efficiency, the present application provides a plastic finished product recycling silo.

[0006] The present application provides a plastic finished product recycling silo that adopts the following technical solution:

[0007] A plastic finished product circulation silo comprises a silo body and a feed pipe installed through the upper side of the silo body, a discharge pipe is installed through the lower side of the silo body, and an air duct is also installed through the side wall of the silo body. The silo body comprises an inner shell and an outer shell, the outer shell is wrapped around the outer side of the inner shell, the air duct is connected to the inner shell, a vertical rod is rotatably installed in the inner shell, the vertical rod is arranged along the length direction of the inner shell, a turntable is fixed on the vertical rod, the center point of the turntable is in the same straight line with the axis of the vertical rod, a motor is fixed on the upper side of the outer shell, the upper end of the vertical rod passes through the inner shell and the outer shell and is fixedly connected to the output end of the motor.

[0008] By adopting the above technical solution, air is supplied to the silo through the air duct, so that the temperature of the air duct circulates in the inner shell, and the motor drives the vertical rod to rotate while driving the turntable to rotate. After the material falls on the turntable, it can automatically slide and fall in the direction away from the vertical rod, which can be better mixed and ensure that the material is in better contact with the air supplied by the air duct. The inner shell and the outer shell form a double-layer structure, which helps to reduce the heat loss of the silo body during the insulation stage, thereby more accurately controlling the temperature of the material in the material layer body.

[0009] Optionally, the turntable has an inclined surface that gradually slopes downward from a side close to the vertical rod to a side away from the vertical rod, and the turntable is a mesh plate with fine mesh holes.

[0010] By adopting the above technical solution, the material entering the inner shell from the feed pipe falls onto the inclined turntable, wherein a part of the material slides downward along the inclined surface of the turntable, and another part of the material slides vertically from the mesh, thereby further ensuring the uniform mixing of the internal material and ensuring that the temperature between the material particles is more uniform.

[0011] Optionally, there are multiple turntables, and the multiple turntables are arranged at intervals along the length direction of the vertical rod.

[0012] By adopting the above technical solution, multiple turntables enable the material to pass through the turntable layer by layer, further improving the mixing effect of the material and ensuring that the temperature of the material particles is more uniform.

[0013] Optionally, the upper surface of each of the turntables is provided with an inclined cleaning rod, the cleaning rod is obliquely fixed on the inner shell, and the cleaning rod is parallel to the inclined surface of the turntable.

[0014] By adopting the above technical solution, after the material falls on the turntable, the cleaning rod sweeps a layer of material located on the upper side of the turntable, causing it to fall along the inclined surface of the turntable, further improving the mixing effect of the material.

[0015] Optionally, an extraction pipeline is installed through the upper side of the silo body, and a vacuum pump is installed on the extraction pipeline.

[0016] By adopting the above technical solution, the divergent gas inside the silo body can be extracted by the vacuum pump through the extraction pipe, which is convenient for the subsequent collection and treatment of the unpleasant or harmful gas brought out by the drying and heat dissipation of the material.

[0017] Optionally, a knife valve is installed on the discharge pipe.

[0018] By adopting the above technical solution, the knife valve only controls the discharge of materials, reducing the influence of complex structure on control accuracy and improving the efficiency of the overall material processing link.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The air is supplied to the silo through the air duct, so that the temperature of the air duct circulates in the inner shell. The motor drives the vertical rod to rotate and drives the turntable to rotate. After the material falls on the turntable, it can automatically slide and fall away from the vertical rod, which can be better mixed and ensure that the material is in better contact with the air sent in by the air duct. The inner shell and the outer shell form a double-layer structure, which helps to reduce the heat loss of the silo body during the insulation stage, so as to more accurately control the temperature of the material in the material layer body;

[0021] 2. The material entering the inner shell from the feed pipe falls on the inclined turntable, part of which slides down along the inclined surface of the turntable, and the other part of the material slides vertically from the mesh, further ensuring the uniform mixing effect of the internal material and ensuring a more uniform temperature between the material particles;

[0022] 3. The diffused gas inside the silo body can be extracted by the vacuum pump through the extraction pipe, which is convenient for the subsequent collection and treatment of the unpleasant or harmful gas brought out by the drying and heat dissipation of the material.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 2-3 This application is described in further detail.

[0028] The embodiment of the present application discloses a plastic finished product recycling silo.

[0029] Reference Figure 2A plastic finished product circulation silo includes a silo body 1 arranged vertically, a feed pipe 2 is installed through the upper side of the silo body 1, and the material enters the silo body 1 through the feed pipe 2, and the projection of the axis of the feed pipe 2 and the axis of the silo body 1 in the vertical direction do not overlap. A discharge pipe 3 is installed through the lower side of the silo body 1, and a knife valve 31 is installed on the discharge pipe 3, and the knife valve 31 controls the opening and closing of the discharge pipe 3. A plurality of air ducts 4 are also installed through the peripheral side wall of the silo body 1, and a valve 41 is installed on each air duct 4, and hot air or cold air can be transported into the silo body 1 through the air duct 4, so as to heat or cool the material in the silo body 1.

[0030] Reference Figure 3 The silo body 1 includes an inner shell 11 and an outer shell 12. The inner shell 11 is located on the inner side of the outer shell 12. The axes of the inner shell 11 and the outer shell 12 are located in the same straight line. The upper sections of the inner shell 11 and the outer shell 12 are both cylindrical, and the lower sections are both conical bucket structures. The double-layer structure formed by the inner shell 11 and the outer shell 12 helps to reduce the heat loss of the material during the insulation stage and achieves an insulation effect.

[0031] A vertical rod 13 is vertically installed in the inner shell body 11, and the axis of the vertical rod 13 is located in the same straight line as the axis of the inner shell body 11. The upper end of the vertical rod 13 is rotatably connected to the inner shell body 11. A plurality of turntables 14 are fixed at intervals in the length direction of the vertical rod 13. The centers of the turntables 14 are fixed to the vertical rod 13, and the turntables 14 have an inclined surface that gradually tilts downward from a side close to the vertical rod 13 to a side away from the vertical rod 13.

[0032] The turntable 14 is a mesh plate with fine meshes. When the material falls on the inclined turntable 14, a part of the material slides down along the inclined surface of the turntable 14, and the other part of the material falls from the screen, thereby achieving the effect of uniform mixing of the internal materials.

[0033] A motor 15 is fixed to the upper side of the outer shell 12 , and the upper end of the vertical rod 13 passes through the inner shell 11 and the outer shell 12 . The output end of the motor 15 is fixedly connected to the upper end of the vertical rod 13 . The motor 15 can drive the vertical rod 13 to rotate, thereby realizing the rotation of the turntable 14 .

[0034] A plurality of cleaning rods 16 extending toward the turntable 14 are also fixed to the inner side of the inner shell 11 . The number of the cleaning rods 16 is the same as the number of the turntables 14 . A cleaning rod 16 is installed on the upper surface of each turntable 14 , and the cleaning rods 16 are parallel to the upper surface of the turntable 14 .

[0035] An extraction pipe 5 is also installed through the silo body 1, and a vacuum pump 51 is installed on the extraction pipe 5. The extraction pipe 5 is connected to the inner shell 11, and harmful gases generated in the inner shell 11 are sucked out by the vacuum pump 51, which is convenient for subsequent collection and treatment.

[0036] The implementation principle of a plastic finished product recycling silo in the embodiment of the present application is:

[0037] The material enters the inner shell 11 from the feed pipe 2, and the inclined turntable 14 causes part of the material to slide down obliquely, and part of the material falls vertically from the mesh. The cleaning rod 16 stirs the material on the surface of the turntable 14 to achieve uniform mixing of the material, and the cold air or hot air enters from the air duct 4 to achieve internal circulation in the inner shell 11, so as to more accurately control the material temperature. The double-layer silo body 1 structure reduces the diffusion and loss of internal temperature; the exhaust gas in the inner shell 11 is extracted from the extraction pipe 5, and finally the material is discharged from the discharge pipe 3, which improves the efficiency of the overall material processing link.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
