Description

Technical Field

[0001] This utility model relates to the field of storage silo technology, and in particular to a resin material storage silo. Background Technology

[0002] Liquid resin materials are widely used in the manufacture of composite materials, such as glass fiber reinforced composites and carbon fiber reinforced composites. They are also used in processes such as casting, molding, and coating.

[0003] A resin material storage silo is a device specifically designed for storing resin materials and is widely used in industries such as chemicals, plastics, and coatings. For example, the existing technology, Chinese Patent Publication No. "CN219602123U", provides a submerged resin storage silo, which includes a storage barrel and a pre-buried pit. The storage barrel is buried in the pre-buried pit. The storage barrel is equipped with an inner liner and an outer liner. The top of the outer liner is equipped with an annular cover, and the top of the inner liner is equipped with a sealing cover. The outer liner wraps around the outside of the inner liner, and the inside of the outer liner is filled with a first insulation cotton. The bottom of the storage barrel is equipped with an anti-corrosion base plate, and the top surface of the anti-corrosion base plate has an installation groove, which is filled with a second insulation cotton. This invention, by setting up a storage tank and a precast pit, allows the storage tank to be buried in the precast pit, thereby utilizing the underground temperature to keep the storage tank in a constant temperature environment. This facilitates the storage of resin inside the storage tank, ensuring the quality of the resin. Furthermore, the combined use of an outer liner, a first insulation cotton, an anti-corrosion base plate, and a second insulation cotton improves the insulation effect of the storage tank, which is beneficial for resin storage.

[0004] Currently, when storing resin materials, it is necessary not only to encapsulate and preserve them, but also to design storage containers according to actual conditions, such as temperature and ease of material retrieval. Most current storage containers are simple tank structures. In winter, some resins cannot adapt to low-temperature storage, so the containers need to have a certain heating capacity. At the same time, when retrieving materials, due to the high adhesion of some resins, it is difficult to achieve a stable and continuous discharge efficiency by simply relying on gravity.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4A resin material storage silo includes a base 1, a storage mechanism 2 at the upper end of the base 1, and a sealing mechanism 3 at the upper end of the storage mechanism 2. The storage mechanism 2 includes a material tank 20, and a heat-conducting sleeve 21 is fixedly wrapped around the outer wall of the material tank 20. The heat-conducting sleeve 21 completely surrounds the side walls and bottom of the material tank 20, allowing for better and more uniform heating when the liquid resin in the material tank 20 is heated and stored. The bottom of the material tank 20 has a conical structure, which also facilitates smoother discharge. The heat-conducting sleeve 21 is made of aluminum alloy and has several annular equidistant rings. The distributed heating elements 22 are connected in parallel to the same external temperature control switch via wires. The heating temperature of the heating elements 22 can be reasonably controlled by the temperature control switch. The heating elements 22 are inserted into the heat-conducting sleeve 21 from the bottom upwards. The heat-conducting sleeve 21 is fixedly wrapped with a grid 23. The grid 23 is made of ceramic material. Ceramic material has good hardness and a certain heat insulation capacity, which can prevent large-area contact with the heat-conducting sleeve 21. At the same time, it can also play a role in explosion prevention for the material tank 20.

[0027] The bottom of the material tank 20 is fixedly provided with a discharge port 24, and a valve 25 is provided on the discharge port 24. The valve core of the valve 25 is embedded inside the discharge port 24. The discharge port 24 can be used to discharge resin.

[0028] The sealing mechanism 3 includes a cover plate 30, a shaft 32, and a spiral blade 35. The cover plate 30 is fixed to the upper end of the material tank 20. The shaft 32 is inserted through the inside of the cover plate 30. The lower end of the shaft 32 is also fixedly wound with a spiral blade 35. The spiral blade 35 is inserted into the inside of the discharge port 24. When the shaft 32 drives the spiral blade 35 to rotate in the forward direction, the spiral blade 35 can be spirally fed downward through the discharge port 24. The outer spiral surface of the spiral blade 35 is in contact with the inner wall surface of the discharge port 24. When the shaft 32 drives the spiral blade 35 to rotate in the reverse direction, the liquid resin can be prevented from being conveyed downward. At this time, in conjunction with the stirring blade 34 and the scraper 39, the liquid resin can be heated evenly during heating. At the same time, the scraper 39 cleans the inner wall of the material tank 20.

[0029] It should be further explained that a bearing 31 is fixed through the center of the cover plate 30, and the shaft 32 is internally connected to the bearing 31. The shaft 32 is also interference-fitted with the inner ring wall of the bearing 31. The bearing 31 is a sealed bearing, which can ensure the sealing effect at the connection between the shaft 32 and the bearing 31.

[0030] It should be further noted that a motor 33 is installed above the cover plate 30. The outer wall of the motor 33 is fixedly assembled to the surface of the cover plate 30 through a bracket. The motor 33 has a drive shaft inside. The end of the shaft is fixedly connected to the end of the shaft rod 32 through a coupling. The motor 33 is a stepper motor and is connected to a forward and reverse switch through wires. The forward and reverse switch is model HY2-8 and can realize forward and reverse rotation with the motor 33.

[0031] It should be further explained that two symmetrically distributed scraper rods 39 are attached to the inner wall of the material tank 20. One end of the scraper rod 39 is fixedly installed on the surface of the shaft 32, and several stirring blades 34 are fixed on the surface of the shaft 32. The other end of the stirring blades 34 is fixedly installed on the inner side of the scraper rod 39. The stirring blades 34 can uniformly stir the liquid resin when it is heated or when the liquid resin is stored for a long time and stratification occurs. The scraper rods 39 can rotate synchronously, which can prevent the resin from sticking to the inside of the material tank 20.

[0032] It should be further noted that a pressure relief valve 36 is also provided through the surface of the cover plate 30. The connection between the pressure relief valve 36 and the cover plate 30 is fixed by welding. The pressure relief valve 36 can prevent the resin in the heating tank 20 from exploding due to excessive pressure.

[0033] It should be further noted that a feed inlet 37 is also provided through the upper end of the cover plate 30. The feed inlet 37 is fixed to the cover plate 30 by welding. A valve 2 38 is provided on the surface of the feed inlet 37. The valve core of the valve 2 38 is embedded inside the feed inlet 37. The feed inlet 37 can play the role of conveying resin into the material tank 20 when storing resin.

[0034] It should be further explained that the material tank 20 is provided with an annular seat 3001 inside. The upper end of the annular seat 3001 is fixedly installed on the lower end of the cover plate 30. The annular seat 3001 is provided with an annular cavity 3005 inside. Several nozzles 3002 are fixedly inserted through the bottom of the annular seat 3001. The nozzles 3002 are connected to the interior of the annular cavity 3005. The nozzles 3002 have a curved structure and their ends are positioned facing the inner wall of the material tank 20. When cleaning the material tank 20, cleaning liquid or clean water can be sprayed onto the inner wall of the material tank 20 to achieve flow rinsing.

[0035] It should be further explained that the upper end of the annular seat 3001 is fixedly connected to a water inlet 3003, which extends upward through the cover plate 30. The connection between the water inlet 3003 and the cover plate 30 is fixed by adhesive. A valve 3004 is provided on the surface of the water inlet 3003. The valve core of the valve 3004 is embedded inside the water inlet 3003. The water inlet 3003 can be connected to an external water pump to provide sufficient liquid delivery pressure during flushing.

[0036] Working method: This solution achieves uniform heating through built-in electric heating tube 22 and heat-conducting sleeve 21. The heat-conducting sleeve 21 is made of aluminum alloy, which has good thermal conductivity and can quickly transfer the heat generated by the electric heating tube 22 to the entire outer wall and bottom of the material tank 20, ensuring that the internal resin is heated evenly. The grid 23 is wrapped around the outside of the heat-conducting sleeve 21, which not only serves as heat insulation but also prevents external objects from directly contacting the high-temperature components. At the same time, its ceramic material has explosion-proof function, enhancing safety. The conical bottom design of the material tank 20, combined with the heating system, can reduce the viscosity of the resin, avoid blockage caused by low-temperature solidification, and ensure smooth discharge. In addition, the stirring blade 34 and scraper 39 rotate periodically under the drive of motor 33, further promoting uniform heating of the resin and preventing local overheating or stratification.

[0037] The storage silo achieves precise resin delivery through the coordinated action of the spiral blade 35 and the valve 25 at the discharge port 24. When discharge is required, the motor 33 drives the spiral blade 35 to rotate in the forward direction via the shaft 32. Its outer spiral surface fits tightly against the inner wall of the discharge port 24, forming a forced feeding channel that pushes the resin at the bottom of the cone downwards in a spiral motion, achieving controllable discharge. When rotating in the reverse direction, the spiral blade 35 forms a sealing barrier to prevent resin flow. The valve 25 is embedded in the discharge port 24 to further enhance the sealing and prevent leakage. The pressure relief valve 36 automatically adjusts the pressure inside the tank during heating or storage to prevent pressure buildup caused by temperature rise and ensure system safety.

[0038] An annular spray structure is also designed inside the material tank 20 to achieve efficient cleaning. The annular seat 3001 is fixed below the cover plate 30, and its annular cavity 3005 is connected to an external water pump through the water inlet interface 3003. High-pressure water or cleaning liquid is sprayed radially through the curved nozzle 3002 to cover the inner wall of the material tank 20. The curved structure of the nozzle 3002 directionally scours, and combined with the rotation of the scraper 39, it can remove residual resin. When the motor 33 drives the shaft 32, the stirring blade 34 and the scraper 39 rotate synchronously to help peel off the adhering substances on the inner wall and improve cleaning efficiency.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
