[0002] A plastic storage silo is a device used to store plastics. It typically has a cylindrical or prismatic upper structure and a lower structure that narrows into a funnel shape with a discharge port. The inlet is usually located in the middle of the upper structure. In use, material enters the silo through the inlet and is stored thereafter; the material can then be discharged through the discharge port.

[0003] Commonly available storage silos, such as the patent document with patent number CN202122010820.7 entitled "A Storage Silo Device for PET Plastic Bottle Flakes," include a silo support, a silo, a hopper, a bottle flake conveying and feeding mechanism, and a discharging mechanism.

[0004] However, during the actual production and application of the storage silo, the inventors discovered the following problems with the existing technology: after the material falls from the feed inlet, it will concentrate in the middle area of ​​the silo, forming a material accumulation area, which will result in uneven material distribution inside the silo and affect the stability of the silo structure. Utility Model Content

[0005] This application provides a plastic mixture storage silo to solve the technical problem that in the feeding process of existing storage silos, a material accumulation area easily forms in the middle, resulting in uneven material distribution inside the silo and affecting the structural stability of the silo.

[0006] This application provides a plastic mixture storage silo, including:

[0007] Support frame;

[0008] The main body of the silo is fixed on the support frame. The main body of the silo includes an upper silo and a lower silo connected together. The upper silo has a feed inlet in the middle of the top and a discharge outlet in the middle of the bottom of the lower silo.

[0009] The material guiding assembly includes a first material guiding component and a second material guiding component. The first material guiding component is located in the upper chamber and directly below the inlet, and the second material guiding component is located in the lower chamber and directly above the outlet. Both the first material guiding component and the second material guiding component have a conical structure, and the pointed end of the cone faces the inlet.

[0010] Furthermore, the diameter of the second guide member is larger than the diameter of the first guide member.

[0011] Furthermore, the first guide member and the second guide member are coaxial, and the axis of the first guide member passes through the middle of the feed inlet and the discharge outlet.

[0012] Furthermore, the material guiding assembly also includes a first fixed bracket, which is connected to the inner wall of the upper chamber, and the first material guiding component is fixed on the first fixed bracket.

[0013] Furthermore, the material guiding assembly also includes a second fixed bracket, which is connected to the inner wall of the lower chamber, and the second material guiding component is fixed on the second fixed bracket.

[0014] Furthermore, it also includes a mixing assembly, which includes a mixing drive and a mixing screw. The mixing drive is located outside the lower chamber, and the mixing screw is located inside the lower chamber and below the second guide. The mixing drive is connected to the mixing screw, and the mixing drive drives the mixing screw to rotate inside the lower chamber.

[0015] Furthermore, an inspection port is provided on the top of the upper chamber, and the inspection port is located on one side of the feed inlet.

[0016] Furthermore, a vent is provided on the top of the upper chamber, and the vent is located on the other side of the feed inlet.

[0017] The advantages of this utility model are:

[0018] In this embodiment, a first guide component is provided in the upper hopper. After the material enters through the feed inlet, the material falls along the surface of the first guide component into the hopper body, so that the material is dispersed inside the hopper body, preventing the material from accumulating in the middle of the hopper body and forming a material accumulation area, so that the material is distributed as evenly as possible inside the hopper body, and avoiding affecting the stability of the hopper body structure.

[0019] In this embodiment, while a first guide component is provided in the upper chamber, a second guide component is also provided in the lower chamber. The first guide component guides the incoming material to prevent it from accumulating or clogging near the inlet.

[0031] like Figures 1 to 3 As shown in the figure, this application embodiment provides a plastic mixture storage silo, including a support frame 1, a silo body 2, and a material guiding assembly 3. The silo body 2 is fixed to the support frame 1. The silo body 2 includes an upper silo body 21 and a lower silo body 22 connected together. The upper silo body 21 has a feed inlet 23 in the middle of its top, and the lower silo body 22 has a discharge outlet 24 in the middle of its bottom. The material guiding assembly 3 includes a first material guiding component 31 and a second material guiding component 32. The first material guiding component 31 is located inside the upper silo body 21 and directly below the feed inlet 23, and the second material guiding component 32 is located inside the lower silo body 22 and directly above the discharge outlet 24. Both the first material guiding component 31 and the second material guiding component 32 have a conical structure, and the pointed end of the cone faces the feed inlet 23.

[0032] In this embodiment, a first guide member 31 is provided inside the upper hopper 21. After the material enters through the inlet 23, it falls along the surface of the first guide member 31 into the hopper body 2, dispersing the material inside the hopper body 2 and preventing it from accumulating in the middle of the hopper body 2 to form a material accumulation zone. This ensures that the material is distributed as evenly as possible inside the hopper body 2, avoiding any impact on the structural stability of the hopper body 2. In addition to the first guide member 31 in the upper hopper 21, this embodiment also provides a second guide member 32 in the lower hopper 22. The first guide member 31 guides the incoming material, preventing it from accumulating or clogging near the inlet 23. When discharging material, it flows along the surface of the second guide member 32 into the discharge port 24 and out, guiding the material towards the discharge port 24 for a smoother discharge process.

[0033] Since both the first guide member 31 and the second guide member 32 have a conical structure, and the pointed end of the cone faces the inlet 23, the material can flow along the surface of the cone, and the material is less likely to stagnate at the pointed end during the flow, reducing material accumulation. The conical design of the first guide member 31 and the second guide member 32 is suitable for materials with poor flowability, ensuring smooth material flow.

[0034] When the material enters the main body 2 of the silo, it has a certain speed and impact force. The first guide component 31 can play a buffering role, reduce the impact of the material on the main body 2 of the silo, and extend the service life of the silo.

[0035] In one embodiment, the diameter of the second guide member 32 is larger than the diameter of the first guide member 31. Because the diameter of the first guide member 31 is relatively small, it can guide the material to various parts of the upper chamber 21, making the material distribution within the upper chamber 21 relatively dispersed and better suited to the larger space of the upper chamber 21. Because the diameter of the second guide member 32 is relatively large, its larger diameter results in a larger surface area, effectively guiding the material along its surface towards the discharge port 24, improving discharge efficiency. The diameter of the second guide member 32 can be twice the diameter of the first guide member 31. Preferably, the diameter of the first guide member 31 is 250 mm, and the diameter of the second guide member 32 is 500 mm.

[0036] In one embodiment, the first guide member 31 and the second guide member 32 are coaxial, and the axis of the first guide member 31 passes through the middle of the inlet 23 and the outlet 24. The coaxial design of the inlet 23, the first guide member 31, the second guide member 32, and the outlet 24 allows the material to enter through the inlet 23 and move directly downwards along the conical surface of the first guide member 31. Then, the material can flow directly to the outlet 24 through the conical surface of the second guide member 32. This reduces changes in direction and resistance during material flow, preventing material accumulation between the first guide member 31 and the second guide member 32 and reducing the possibility of material blockage.

[0037] To secure the first guide component 31 within the upper chamber 21, the guide assembly 3 further includes a first fixing bracket 4. The first fixing bracket 4 is connected to the inner wall of the upper chamber 21, and the first guide component 31 is fixed to the first fixing bracket 4. The first fixing bracket 4 can be fixed to the inner wall of the upper chamber 21 by welding or screws, and the first guide component 31 can also be fixed to the first fixing bracket 4 by welding or screws.

[0038] To secure the second guide component 32 within the lower chamber 22, the guide assembly 3 further includes a second fixing bracket 5. The second fixing bracket 5 is connected to the inner wall of the lower chamber 22, and the second guide component 32 is fixed to the second fixing bracket 5. The second fixing bracket 5 and the inner wall of the lower chamber 22 can be connected by welding or screws, and the second guide component 32 and the second fixing bracket 5 can also be fixed by welding or screws.

[0039] To ensure more uniform material distribution and smoother discharge within the lower hopper 22, the plastic mixture storage hopper in this embodiment further includes a mixing assembly. The mixing assembly includes a mixing drive and a mixing screw 6. The mixing drive is located outside the lower hopper 22, while the mixing screw 6 is located inside the lower hopper 22 and below the second guide member 32. The mixing drive is connected to the mixing screw 6, driving the mixing screw 6 to rotate within the lower hopper 22. Preferably, the mixing drive is a motor. The mixing screw 6 can be rotatably connected to the lower hopper 22 via bearings or similar components. After the mixing drive is activated, it drives the mixing screw 6 to reciprocate within the lower hopper 22, thereby ensuring more uniform material distribution within the lower hopper 22.

[0040] like Figure 4 As shown, in one embodiment, the top of the upper chamber 21 is also provided with an inspection port 25, which is located on one side of the feed inlet 23. The top of the upper chamber 21 is also provided with a vent 26, which is located on the other side of the feed inlet 23. The diameter of the inspection port 25 can be made relatively large to facilitate maintenance.

[0041] The support frame 1 in this embodiment can be welded from channel steel. The bottom of the support frame 1 can be directly fixed to the ground or a table. The hopper body 2 and the support frame 1 can be connected by welding, and the upper hopper body 21 and the lower hopper body 22 can also be connected by welding. The height of the support frame 1 in this embodiment can be 3150mm, the height of the upper hopper body 21 can be 1800mm, the height of the lower hopper body 22 can be 850mm, and the diameter of the upper hopper body 21 can be 1910mm. The diameter of the feed inlet 23 can be 200mm, the diameter of the vent 26 can also be 200mm, the diameter of the inspection port 25 can be 500mm, and the diameter of the discharge port 24 can be 400mm.

[0042] In the storage state, the discharge port 24 of the plastic mixture storage silo in this embodiment can be blocked by a discharge gate or the like to prevent material from flowing out. When it is necessary to discharge and feed material, the discharge port 24 can be aligned with the feed port 23 of the screw conveyor, and the material can be fed in conjunction with the screw conveyor.

[0043] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
