AI Technical Summary
Powdered phenolic resin is prone to clumping due to air humidity during storage, and its uneven distribution in the storage tank leads to excessive pressure in the central area, making it even more prone to clumping. Existing technologies are unable to effectively solve this problem.
Heating pipes and feeding components are arranged inside the storage tank. The heating pipes improve the temperature uniformity inside the tank, and the feeding components allow the phenolic resin to flow in along the central feeding pipe and then disperse to the surrounding area under the action of the bottom plate, reducing the amount of phenolic resin in the central area. A simple baffle structure is used to replace the pneumatic valve, and the tank strength is enhanced by combining the heat preservation chamber and the reinforcing rib structure.
This effectively prevents the clumping of powdered phenolic resin, achieves uniform distribution of phenolic resin inside the tank, improves storage stability and efficiency, and reduces maintenance difficulty.

Abstract
Description
Technical Field
[0001] This application belongs to the field of container technology for storing or transporting objects or materials, and particularly relates to a powdered phenolic resin storage tank. Background Technology
[0002] Before bagging, phenolic resin needs to be pulverized into 200-300 mesh powder using a pulverizer. Then, it is stored in a storage tank. Opening the outlet of the storage tank allows the powdered phenolic resin to flow out from the outlet, thus completing the bagging process.
[0003] When powdered phenolic resin is stored in a storage tank, it is prone to clumping due to factors such as air humidity. In addition, when the powdered phenolic resin enters the storage tank, it enters the tank through the inlet, resulting in a higher concentration of phenolic resin in the central area and a lower concentration around the edges. This uneven distribution leads to higher pressure in the central area, making it more prone to clumping.
[0004] In addition, during the production of phenolic resin, the reaction between formaldehyde and phenol in the reactor generates heat. This heat is condensed and discharged by the condenser, and can also be used in the storage of phenolic resin. Utility Model Content
[0005] In order to solve the above problems, this application provides a powdered phenolic resin storage tank.
[0006] The purpose of this application is to provide a powdered phenolic resin storage tank that prevents the phenolic resin from clumping by heating the tank. In addition, by changing the distribution of the phenolic resin in the tank, the amount of phenolic resin in the central area is reduced, thus preventing the phenolic resin from clumping in the tank.
[0007] To achieve the purpose of this application, the technical solution of this application is as follows:
[0008] A powdered phenolic resin storage tank includes a storage silo, a discharge silo at the lower end of the storage silo, a discharge port at the lower end of the discharge silo, a silo roof at the upper end of the storage silo, an upper connecting pipe on the silo roof, a heating pipe at the lower end of the upper connecting pipe, the heating pipe being arranged in the upper-middle part of the storage silo, a lower connecting pipe on the discharge silo, a lower heating pipe at the lower-middle part of the storage silo, the lower connecting pipe connecting to the lower heating pipe, and a feeding assembly on the silo roof, the feeding assembly including a central feeding pipe, the lower end of the central feeding pipe being a tapered pipe, and a side of the central feeding pipe being provided with... The overflow pipe is arranged at an incline, and the lower end of the tapered pipe is provided with a connecting plate arranged at intervals. The lower end of the connecting plate is provided with a tapered bottom plate. In this application, by arranging a heating pipe inside the tank, the temperature inside the tank is increased, especially in continuous rainy weather, to prevent the powdered phenolic resin inside the tank from clumping. In addition, when the phenolic resin passes through the feeding assembly, it flows into the tank along the central feeding pipe and is dispersed to the periphery of the tank under the action of the bottom plate. Excess phenolic resin is dispersed to the periphery of the tank along the overflow pipe, thereby reducing the amount of phenolic resin in the central area.
[0009] Furthermore, an insulation chamber is provided outside the feeding hopper, and a cavity is provided between the feeding hopper and the insulation chamber, with the lower connecting pipe arranged inside the cavity.
[0010] Furthermore, pipe clamps are installed on the inner wall of the insulation chamber to fix the lower connecting pipe to the insulation chamber.
[0011] Furthermore, the upper end of the insulated bin is fixedly connected to the storage bin, and the lower end of the insulated bin is fixedly connected to the discharge port.
[0012] Furthermore, a baffle is installed at the end of the overflow pipe, which is hinged to the overflow pipe. A pull rope is installed on the baffle, which passes through the top of the silo. A pull ring is installed at the end of the pull rope away from the baffle, and the pull ring is fixed to the top of the silo.
[0013] Furthermore, the upper, middle and lower ends of the storage silo are provided with annular reinforcing ribs, and the outer periphery of the storage silo is provided with vertical ribs evenly distributed around the center of the storage silo.
[0014] Furthermore, the upper end of the vertical rib is fixedly connected to the annular reinforcing rib at the upper end of the storage silo, and the lower end of the vertical rib is fixedly connected to the annular reinforcing rib at the lower end of the storage silo.
[0015] Furthermore, the insulation chamber has through holes and a sealing cover, which blocks the through holes. The lower connecting pipe and the lower heating pipe are fixedly connected by clamps.
[0016] Furthermore, a control valve is installed at the discharge port of the feeding hopper, and a discharge pipe is installed on the control valve.
[0017] Furthermore, fixed wing plates are installed on the outer periphery of the storage silo.
[0018] Compared with the prior art, the beneficial effects of this application are as follows:
[0019] 1. In this application, the heating pipe is arranged inside the tank and divided into upper and lower areas to avoid the temperature drop at the end of the heating pipe due to its excessive length, so as to ensure a uniform temperature inside the storage tank and prevent the powdered phenolic resin inside the tank from clumping.
[0020] 2. The feeding assembly of this application includes a central feeding pipe and an overflow pipe. When powdered phenolic resin enters the tank from the feeding assembly, the powdered phenolic resin first flows along the central feeding pipe and then flows to the periphery of the tank under the action of the bottom plate. Excess powdered phenolic resin will flow to the periphery of the tank along the overflow pipe, thereby reducing the amount of phenolic resin in the central area and making the distribution of phenolic resin in the tank more uniform in the vertical direction.

[0031] Example 1
[0032] This embodiment is a powdered phenolic resin storage tank for storing powdered phenolic resin. The flaky or granular phenolic resin is processed by a pulverizer to form 200-300 mesh powdered phenolic resin, which is then stored, packaged, and transported. This embodiment relates to the storage process of powdered phenolic resin.
[0033] The storage tank includes a storage bin 2, which is cylindrical. A discharge bin 3 is installed at the lower end of the storage bin 2. The discharge bin 3 is connected to the storage bin 2 by bolts. The discharge bin 3 is inverted conical and has a discharge port at the lower end. The storage bin 2 has a bin top 7 at the upper end, which is connected to the upper end of the storage bin 2. The bin top 7 is flat or arc-shaped.
[0034] In this embodiment, due to the relatively high height of the storage tank, to ensure a more uniform temperature, the storage tank is divided into two parts: the first part is the heating of the storage silo 2, and the second part is the heating of the unloading silo 3. Specifically, an upper connecting pipe 8 is installed on the top 7 of the silo, and a heating pipe 9 is installed at the lower end of the upper connecting pipe 8. The heating pipe 9 is arranged in the upper middle part of the storage silo 2, and forms a loop inside the storage silo 2. The cooled steam flows along the upper connecting pipe 8 into the heating pipe 9 and then flows out from another upper connecting pipe 8. A lower connecting pipe 20 is installed on the unloading silo 3, and a lower heating pipe 10 is installed in the lower middle part of the storage silo 2. The lower connecting pipe 20 is connected to the lower heating pipe 10. The cooled steam flows along the lower connecting pipe 20 into the lower heating pipe 10 and then flows out from another lower connecting pipe 20. By arranging heating pipes inside the tank, the temperature inside the tank is increased, especially in continuous rainy weather, to prevent the powdered phenolic resin inside the tank from clumping.
[0035] In this embodiment, the heat inside the heating tube is provided by the heat generated during the reaction of the phenolic resin.
[0036] In this embodiment, to ensure uniform distribution of phenolic resin material and avoid concentration of phenolic resin in the central area of the storage tank, and instead minimize phenolic resin in the central area and maximize phenolic resin at the edges, a feeding assembly 13 is installed on the top 7 of the silo. Specifically, the feeding assembly 13 includes a central feeding pipe, with a cylindrical upper end and a tapered lower end 14. An inclined overflow pipe 15 is installed on the side of the central feeding pipe, and the lower end of the tapered pipe 14 has spaced connecting plates 16. A conical bottom plate 17 is installed at the lower end of the receiving plate 16. When phenolic resin passes through the feeding assembly 13, it flows into the tank along the central feed pipe. When the powdered phenolic resin reaches the bottom plate 17 from the central feed pipe, it moves outwards along the bottom plate 17 and passes through the gaps between the connecting plates 16. Under the action of the bottom plate 17, it disperses into the tank. Due to the presence of the conical pipe 14, the outflow speed of the powdered phenolic resin from the central feed pipe slows down. Excess phenolic resin will disperse into the tank along the overflow pipe 15, thus reducing the outflow rate of the central feed pipe. The amount of phenolic resin in the central region is reduced because the phenolic resin in the tank is distributed outwards, forming an inverted cone-shaped cavity in the central region. Compared with existing solutions, the height of phenolic resin in various positions within the tank is more uniform, avoiding the problem of excessive phenolic resin in the central region. More specifically, when the overflow pipe 15 is not needed for discharge, such as in the initial feeding stage, the discharge from the overflow pipe 15 is not required or is reduced; instead, the central region of the tank is filled first. In this embodiment, a baffle 18 is installed at the end of the overflow pipe 15. The baffle 18 is hinged to the overflow pipe 15. A pull rope 19 is installed on the baffle 18. The pull rope 19 passes through the top of the silo 7. The end of the pull rope 19 away from the baffle 18 has a pull ring, which is fixed to the top of the silo 7. By fixing the pull ring at different positions on the top of the silo 7, the opening and closing angle of the baffle 18 can be changed. This embodiment uses this simple structure to replace the currently used pneumatic valve. Because the inside of the tank is a dusty environment, the valve used has high requirements and is inconvenient to maintain. The simple baffle 18 structure can avoid the influence of the dusty environment inside the tank and has a low maintenance rate.
[0037] In this embodiment, an insulated bin 6 is installed outside the feeding bin 3. A cavity exists between the feeding bin 3 and the insulated bin 6. A lower connecting pipe 20 is arranged within the cavity. A pipe clamp 21 is installed on the inner wall of the insulated bin 6, fixing the lower connecting pipe 20 to the insulated bin 6. The upper end of the insulated bin 6 is fixedly connected to the storage bin 2, and the lower end of the insulated bin 6 is fixedly connected to the discharge port. The fixed connection method is bolt connection, making the insulated bin 6 detachably connected to the storage bin 2 and the feeding bin 3. When it is necessary to... When transferring heat inside the tank, the insulation chamber 6 is installed, and the lower connecting pipe 20 is connected to the lower heating pipe 10. Specifically, the insulation chamber 6 has a through hole and a sealing cover is installed on the insulation chamber 6. The sealing cover blocks the through hole. The lower connecting pipe 20 and the lower heating pipe 10 are fixedly connected by a clamp. The sealing cover is opened, and the lower connecting pipe 20 and the lower heating pipe 10 are connected together by the clamp. Then the sealing cover is closed, and the insulation chamber 6 and the cavity are used to insulate the feeding hopper 3.
[0038] As a more specific implementation, this embodiment has annular reinforcing ribs 11 installed at the upper, middle, and lower ends of the storage silo 2. Vertical ribs 12, evenly distributed around the center of the storage silo 2, are installed around its outer periphery. The upper ends of the vertical ribs 12 are fixedly connected to the annular reinforcing ribs 11 at the upper end of the storage silo 2, and the lower ends of the vertical ribs 12 are fixedly connected to the annular reinforcing ribs 11 at the lower end of the storage silo 2. Correspondingly, the discharge silo 3 has a corresponding rib structure to improve the strength of the tank, ensuring that the tank can be taller and have a larger diameter, thereby storing more material. Furthermore, since the phenolic resin inside the storage tank needs to be packaged, a control valve 4 is installed at the discharge port of the discharge silo 3, and a discharge pipe 5 is installed on the control valve 4. The discharge pipe 5 is inclined... The storage tank is arranged at an angle, supported by bracket 1, so that the end of the discharge pipe 5 is about 1 meter from the ground. The height of the storage tank is between 3 and 4 meters. The top 7 of the storage tank is located on the second floor of the steel frame. The storage silo 2 passes through the frame platforms of the first and second floors of the steel frame. The discharge silo 3 and the discharge pipe 5 are located entirely on the first floor of the steel frame. In this embodiment, a fixed wing plate is installed on the outer periphery of the storage silo 2. The fixed wing plate is connected to the vertical rib plate 12 and the annular reinforcing rib plate 11 at the upper end of the storage silo 2. The fixed wing plate is connected to the second floor platform of the steel frame. In addition, in this embodiment, temperature sensors and other equipment are also required to detect the temperature inside the tank, and sampling ports are opened to randomly sample and test the phenolic resin inside the tank.
