Description

Technical Field

[0001] This utility model relates to the field of particle storage technology, specifically to a polyurethane particle storage device. Background Technology

[0002] Polyurethane particles are block copolymers composed of polyester or polyether segments and isocyanate segments. The polyester or polyether segments provide flexibility and elasticity, while the isocyanate segments provide hardness and abrasion resistance. This material features high strength, good elasticity, abrasion resistance, aging resistance, suitable hardness, and durability.

[0003] Polyurethane granules are typically produced in large batches, requiring storage before all are shipped. Currently, polyurethane granules are usually stored in packaging bags, which are then stacked in warehouses. However, if stored for too long, the polyurethane granules inside the packaging bags are prone to moisture absorption and clumping, which can lead to problems affecting their normal use. Utility Model Content

[0004] The purpose of this invention is to provide a polyurethane particle storage device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane particle storage device, comprising a support frame, characterized in that: the support frame is provided with a storage component, the storage component comprising a lower tank fixedly mounted on the support frame, an upper tank slidably mounted inside the lower tank, an inlet pipe and an outlet pipe respectively fixedly mounted above the upper tank and below the lower tank, a plurality of upper pipes and lower pipes respectively fixedly mounted inside the upper tank and the lower tank, an air supply pipe communicating with the upper pipes and located above the upper tank, a plurality of hanging ropes, and a plurality of desiccant packets fixedly mounted on the hanging ropes, wherein the upper pipes and lower pipes are each provided with a plurality of through holes located inside the upper tank and the lower tank, the lower pipe is inserted into the upper pipe and slidably connected to the upper pipe, and the hanging ropes and desiccant packets are both located inside the upper pipes and the lower pipes.

[0006] Preferably, the storage assembly further includes a cylinder fixedly disposed above the support and located on the left and right sides of the lower barrel, and a convex ring fixedly disposed on the outer side of the upper barrel, wherein the piston rod of the cylinder is fixedly connected to the convex ring.

[0007] Preferably, guide bars are fixedly provided on both the left and right sides of the upper bucket, and guide grooves matching the guide bars are provided on the inner side wall of the lower bucket, and the guide bars are inserted into the guide grooves and slidably connected to the lower bucket.

[0008] Preferably, the bottom of the lower bucket is conical, and the storage assembly further includes a rotating shaft rotatably disposed inside the upper and lower buckets, several blades fixedly disposed on the rotating shaft and located below the lower tube, and a handle fixedly disposed above the rotating shaft.

[0009] Preferably, the top end of the upper tube is detachably provided with a cover A, and the top end of the hanging rope is fixedly connected to the cover A.

[0010] Preferably, both the discharge pipe and the air supply pipe are detachably equipped with a cover B at their top ends, and a valve is fixedly installed on the discharge pipe.

[0011] Preferably, a number of casters are fixedly installed below the bracket.

[0012] The beneficial effects of this utility model are as follows: When polyurethane granules are to be stored, the valve is closed and all covers A and B are opened. The polyurethane granules are poured into the lower bucket from the feed pipe. When the lower bucket is almost full, the cylinder is activated to push out its piston rod, causing the upper bucket to move upward, thereby increasing the capacity. Because the lower pipe is inserted into the upper pipe and slidably connected to it, the upper pipe will move upward with the upper bucket and then be positioned above the lower pipe. The air supply pipe is connected to an external blowing device, and the external blowing device is activated so that air passes through the air supply pipe and blows into the upper and lower buckets through the through holes on the upper and lower pipes, allowing the interior of the upper and lower buckets to dry quickly. The top of the hanging rope is fixedly connected to cover A, and cover A is installed on the top of the upper pipe so that the hanging rope and desiccant are both located on the upper pipe and the lower pipe. The lower pipe serves to keep both the upper and lower barrels dry. The cover B is installed at the top of the air supply pipe and the discharge pipe to complete the storage of polyurethane granules. When the polyurethane granules are needed, the valve is opened to allow them to fall. At this time, due to friction, the granules may get stuck. Turning the handle drives the shaft and blades to rotate, applying a pushing force to the granules so they fall smoothly. In summary, this invention has the beneficial effects of quickly drying and maintaining the dryness of the barrel's interior, solving the problem that when bagged polyurethane granules are stored in a warehouse for too long, the granules inside the packaging bag easily become damp and clump together, affecting their normal use.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1-4As shown, this utility model discloses a polyurethane particle storage device, including a support 1. The support 1 is provided with a storage component. The storage component includes a lower tank 2 fixedly mounted on the support 1, an upper tank 3 slidably mounted inside the lower tank 2, an inlet pipe 4 and an outlet pipe 5 respectively fixedly mounted above the upper tank 3 and below the lower tank 2, several upper pipes 6 and lower pipes 7 respectively fixedly mounted inside the upper tank 3 and the lower tank 2, an air supply pipe 8 connected to the upper pipe 6 and located above the upper tank 3, several hanging ropes 9, and several packs of desiccant 10 fixedly mounted on the hanging ropes 9. Several through holes 11 are opened on the upper pipes 6 and the lower pipes 7, located inside the upper tank 3 and the lower tank 2. The lower pipe 7 is inserted into the upper pipe 6 and slidably connected to the upper pipe 6. The hanging ropes 9 and the desiccant 10 are both located inside the upper pipes 6 and the lower pipes 7. When storing polyurethane granules, close valve 21 and open all covers A19 and B20. Pour the polyurethane granules into the lower drum 2 through the feed pipe 4. When the lower drum 2 is almost full, activate cylinder 12 to push out its piston rod, causing the upper drum 3 to move upward, thereby increasing its capacity. Since the lower pipe 7 is inserted into the upper pipe 6 and slidably connected to it, the upper pipe 6 will move upward with the upper drum 3 and be positioned above the lower pipe 7. Connect the air supply pipe 8 to the external blowing device and activate the external blowing device. Air will pass through the air supply pipe 8 and be blown into the upper drum 3 and lower drum 2 through the through holes 11 on the upper pipe 6 and lower pipe 7, allowing the interior of the upper drum 3 and lower drum 2 to dry quickly. Secure the top of the hanging rope 9 to the cover A19 and install the cover A19 on the top of the upper pipe 6, ensuring that the hanging rope 9 and the desiccant 10 are evenly positioned. Inside the upper pipe 6 and lower pipe 7, the upper barrel 3 and lower barrel 2 are kept dry. The cover B20 is installed at the top of the air supply pipe 8 and the discharge pipe 5 to complete the storage of polyurethane granules. When the polyurethane granules are to be used, the valve 21 is opened to let the polyurethane granules fall. At this time, due to friction, the polyurethane granules may get stuck. Turning the handle 18 drives the rotating shaft 16 and the blade 17 to rotate, applying a pushing force to the polyurethane granules so that they fall smoothly. In summary, this utility model has the beneficial effects of quickly drying the inside of the barrel and keeping the inside of the barrel dry. It solves the problem that when bagged polyurethane granules are piled up in the warehouse for too long, the polyurethane granules inside the packaging bag are prone to moisture and clumping, which affects the normal use of the polyurethane granules.

[0020] Preferably, the storage assembly further includes cylinders 12 fixedly mounted above the support 1 and located on the left and right sides of the lower bucket 2, and a convex ring 13 fixedly mounted on the outside of the upper bucket 3. The piston rod of the cylinder 12 is fixedly connected to the convex ring 13. Since the piston rod of the cylinder 12 is fixedly connected to the convex ring 13, activating the cylinder 12 to push its piston rod out will push the convex ring 13 and the upper bucket 3 upward, thus facilitating capacity adjustment.

[0021] Preferably, guide strips 14 are fixedly provided on both the left and right sides of the upper bucket 3, and guide grooves 15 matching the guide strips 14 are provided on the inner side wall of the lower bucket 2. The guide strips 14 are inserted into the guide grooves 15 and slidably connected with the lower bucket 2. Since the guide strips 14 are inserted into the guide grooves 15 and slidably connected with the lower bucket 2, they play a guiding role when the upper bucket 3 slides.

[0022] Preferably, the bottom of the lower bucket 2 is conical. The storage assembly further includes a rotating shaft 16 rotatably disposed within the upper bucket 3 and the lower bucket 2, several blades 17 fixedly disposed on the rotating shaft 16 and located below the lower pipe 7, and a handle 18 fixedly disposed above the rotating shaft 16. Because the bottom of the lower bucket 2 is conical, it facilitates the sliding of polyurethane particles towards the discharge pipe 5. Because the several blades 17 are fixedly disposed on the rotating shaft 16 and located below the lower pipe 7, the polyurethane particles may become stuck due to friction when falling. Rotating the handle 18 drives the rotating shaft 16 and the blades 17 to rotate, applying a pushing force to the polyurethane particles, thus ensuring their smooth fall. The handle 18, fixedly disposed above the rotating shaft 16, facilitates the rotation of the rotating shaft 16.

[0023] Preferably, a cover A19 is detachably provided at the top of the upper tube 6, and the top of the hanging rope 9 is fixedly connected to the cover A19. Since the top of the hanging rope 9 is fixedly connected to the cover A19, installing the cover A19 at the top of the upper tube 6 allows the hanging rope 9 and the desiccant 10 to be located inside the upper tube 6 and the lower tube 7, which facilitates the insertion and removal of the desiccant 10.

[0024] Preferably, both the discharge pipe 5 and the air supply pipe 8 are detachably equipped with a cover B20 at their top ends, and a valve 21 is fixedly installed on the discharge pipe 5. The valve 21 fixedly installed on the discharge pipe 5 facilitates the control of the opening and closing of the discharge pipe 5.

[0025] Preferably, a plurality of casters 22 are fixedly installed at the bottom of the support 1. The presence of casters 22 at the bottom of the support 1 facilitates the transfer of the lower bucket 2 and the upper bucket 3.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
