Description

Technical Field

[0001] The utility model relates to the technical field of resin raw material storage, and more specifically, to a resin raw material storage device. Background Art

[0002] Resins are generally considered to be normal metabolic products or secretions of plant tissues, and often coexist with volatile oils in the secretory cells, resin ducts or vessels of plants, especially in the vessels of the heartwood of perennial woody plants. Resins can be divided into addition polymers and condensation polymers. Condensation polymers refer to polymers obtained by condensation polymerization reactions, and the chemical formula of their structural units is different from the molecular formula of the monomers, such as phenolic resins, polyester resins, polyamide resins, etc. The existing storage of resin raw materials is mostly barreled.

[0003] The existing barrels for storing resin raw materials have poor thermal insulation effect. The resin raw materials are easy to condense when encountering high temperatures. When using the resin, the resin raw materials in a barrel cannot be used up at one time, and a certain amount of resin in the barrel needs to be discharged. The existing storage equipment is convenient for controlling the amount of resin raw materials discharged from the barrel. Some manufacturers now also install corresponding structures on the barrels to address the above problems. However, when the barrel needs to be replaced, the complex structure installed on the barrel needs to be replaced together, which increases the cost of replacement and reduces its practicality.

[0018] Beneficial effects:

[0019] 1. Place the storage barrel filled with resin raw materials on the base, and make the discharge pipe of the storage barrel face the appropriate direction, then cover the outside of the storage barrel with a heat insulation cover, and fix the heat insulation cover to the base through a fixing mechanism.

Since the heat insulation cover, gas cylinder and other structures are separately arranged from the storage barrel, when the storage barrel is damaged or needs to be eliminated for other reasons, the storage barrel can be directly eliminated, avoiding the elimination of structures such as the heat insulation cover and gas cylinder along with the storage barrel, thereby reducing the cost of replacement and use and improving its practicality.

[0021] 3. The piston is pushed downward by the electric cylinder, and the air inside the cylinder is transported to the inside of the storage barrel through the outlet pipe, seamless pipe and ventilation pipe, so that the pressure inside the storage barrel is increased, and the resin raw material inside the storage barrel is pushed into the storage barrel.

The top of the storage barrel 1 is connected with a vent pipe 5 and a feeding pipe 6. The top of the feeding pipe 6 is threadedly connected with a sealing cap 35. The resin raw material is conveniently added to the interior of the storage barrel 1 through the feeding pipe 6. The feeding pipe 6 is screwed on the top of the feeding pipe 6 to facilitate sealing the feeding pipe 6. The vent pipe 5 is installed with a first valve 7. The bottom side of the side end of the storage barrel 1 is connected with a discharge pipe 8. The discharge pipe 8 is installed with a second valve 9. The storage barrel 1 is placed on the base 2. The top of the base 2 can The protrusion 31 can be inserted into the groove at the bottom of the storage barrel 1, which is convenient for limiting the storage barrel 1. The heat insulation cover 3 covers the outside of the storage barrel 1. The top of the base 2 is provided with a ring groove 27, and the bottom end of the heat insulation cover 3 is inserted into the inside of the ring groove 27. The side bottom of the heat insulation cover 3 is provided with a U-shaped groove 28 adapted to the discharge pipe 8, which is convenient for limiting the heat insulation cover 3 and covering the outside of the storage barrel 1. The inner wall of the heat insulation cover 3 is fixedly connected with heat insulation cotton 29 to increase the heat insulation effect and keep the storage barrel 1 warm. The interior of the heat insulation cover 3 is provided with a vacuum The cavity 10, the heat shield 3 is connected to the base 2 through a plurality of fixing mechanisms, the piston 11 is provided with a sealing sliding inside the air cylinder 4, the top of the air cylinder 4 is provided with an electric cylinder 12, the telescopic rod of the electric cylinder 12 is fixedly connected to the top of the piston 11, the bottom side of the side end of the air cylinder 4 is connected with an air inlet pipe 13 and an air outlet pipe 14, the air inlet pipe 13 and the air outlet pipe 14 are respectively provided with a first one-way valve 15 and a second one-way valve 16, the air outlet pipe 14 is connected with a seamless pipe 17, the seamless pipe 17 is connected with the ventilation pipe 5 through a quick connector 18, and an observation port 19 is provided on the air cylinder 4, the observation port 19 A transparent plate 20 is fixedly connected to the inside of the cylinder 4, and a scale line 21 is set on the position corresponding to the transparent plate 20. The heat insulation cover 3 is covered on the outside of the storage barrel 1, which can effectively prevent heat from being transferred to the inside of the storage barrel 1, and can prevent the resin raw material inside the storage barrel 1 from solidifying due to high temperature. The corresponding heat insulation structure is separately arranged from the storage barrel 1. When the storage barrel 1 needs to be replaced, the corresponding heat insulation structure is avoided from being replaced together, thereby reducing the replacement cost. At the same time, it is convenient to discharge a certain amount of resin raw material from the inside of the storage barrel 1, thereby improving the practicability of its use.

[0032] In this embodiment, a storage barrel 1 filled with resin raw materials is placed on the base 2, and the discharge pipe 8 of the storage barrel 1 is oriented in a suitable direction. Then, the heat insulation cover 3 is covered on the outside of the storage barrel 1, and the heat insulation cover 3 is fixed to the base 2 by a fixing mechanism. Since the inside of the vacuum chamber 10 on the heat insulation cover 3 is in a vacuum state, a large amount of external heat can be prevented from being transferred to the inside of the storage barrel 1, and the high-temperature solidification of the resin raw materials inside the storage barrel 1 can be prevented. When the storage barrel 1 needs to be replaced, the heat insulation cover 3 is removed from the outside of the storage barrel 1, and then the storage barrel 1 on the base 2 is removed. Then, a new storage barrel 1 is placed on the base 2, and then the heat insulation cover 3 is covered on the outside of the new storage barrel 1, so that it is convenient to replace the storage barrel 1 separately. Since the heat insulation cover 3 and the air cylinder 4 and other structures are separately arranged from the storage barrel 1, when the storage barrel 1 is replaced, the heat insulation cover 3 is removed from the outside of the storage barrel 1, and then the storage barrel 1 on the base 2 is removed. Then, the new storage barrel 1 is placed on the base 2, and then the heat insulation cover 3 is covered on the outside of the new storage barrel 1. When the storage barrel 1 is damaged or needs to be eliminated due to other reasons, the storage barrel 1 can be directly eliminated, which avoids the elimination of structures such as the heat insulation cover 3 and the air cylinder 4 along with the storage barrel 1, thereby reducing the cost of replacement and use and improving its practicality. The piston 11 is pushed downward by the electric cylinder 12, and the air inside the air cylinder 4 is transported to the inside of the storage barrel 1 through the air outlet pipe 14, the seamless pipe 17 and the ventilation pipe 5, so that the pressure inside the storage barrel 1 is increased, and the resin raw material inside the storage barrel 1 is pushed into the storage barrel 1. By observing the moving distance of the piston 11 inside the air cylinder 4 and observing the volume of the air pushed into the storage barrel 1 between the front and rear differences of the movement of the piston 11 through the scale line 21, the amount of the resin raw material pushed out of the storage barrel 1 can be judged, so that it is convenient to discharge the corresponding amount of resin raw material from the storage barrel 1 according to people's use needs.

[0033] See also Figure 2 and Figure 5 The fixing mechanism includes a fixing block 22, and a plurality of slots 23 are evenly arranged on the outside of the heat insulation cover 3. The bottom end of the fixing block 22 is fixedly connected to the top end of the base 2. A screw 24 is threadedly connected to the fixing block 22. A column 25 adapted to the slot 23 is fixedly connected to the side end of the screw 24. The diameter of the column 25 is smaller than the minor diameter of the screw 24 thread. A handle 26 is fixedly connected to the side end of the screw 24.

[0034] In this embodiment, the handle 26 and the screw 24 are rotated clockwise, and the screw 24 moves relative to the fixed block 22 to the side close to the heat insulation cover 3. The screw 24 drives the clamping column 25 to move and insert the clamping column 25 into the corresponding clamping groove 23, thereby facilitating the fixation of the heat insulation cover 3.

[0035] See also Figure 1 and Figure 2The top of the heat insulation cover 3 is connected to a vacuum tube 33 which is in communication with the inside of the vacuum chamber 10. A third valve 34 is installed on the vacuum tube 33. A plurality of support blocks 32 are fixedly connected to the inside of the vacuum chamber 10 to facilitate supporting the heat insulation cover 3 and avoid damage to the heat insulation cover 3 due to the internal pressure difference during the vacuum pumping process.

[0036] In this embodiment, the vacuum tube 33 is connected to an external vacuum pumping device, and then the third valve 34 is opened to evacuate the interior of the vacuum chamber 10 through the external vacuum pumping device. After evacuation, the third valve 34 is closed, and then the external vacuum pumping device is removed from the vacuum tube 33, so that the interior of the vacuum chamber 10 is in a vacuum state.

[0037] In summary, when the overall equipment is in use:

[0038] When in use, place the storage barrel 1 storing the resin raw material on top, and insert the protrusion 31 into the depression at the bottom of the storage barrel 1, and make the discharge pipe 8 face the appropriate position. We can also make a mark on the base 2 so that the discharge pipe 8 is located at the marked position, and then shine the heat insulation cover 3 on the outside of the storage barrel 1, and insert the discharge pipe 8 into the inside of the U-shaped groove 28. At this time, the multiple slots 23 on the heat insulation cover 3 correspond to the positions of the multiple posts 25, and then turn the handle 26 and the screw 24 clockwise, and the screw 24 moves relative to the fixed block 22 to the side close to the heat insulation cover 3. The screw 24 drives the post 25 to move and inserts the post 25 into the corresponding slot 23, thereby fixing the heat insulation cover 3, and preventing a large amount of heat from being transferred to the inside of the storage barrel 1 through the heat insulation cover 3, thereby preventing the resin raw material from solidifying;

[0039] When a certain amount of resin raw material needs to be discharged from the interior of the storage barrel 1, the seamless pipe 17 is sealed and connected to the vent pipe 5 through the quick connector 18, and then the first valve 7 and the second valve 9 are opened. Since the interior of the storage barrel 1 is in a sealed state, the resin will not be discharged from the interior of the discharge pipe 8 due to the effect of pressure. Then the piston 11 is pulled upward by the electric cylinder 12. During the upward movement of the piston 11, the pressure inside the cylinder 4 is lower than the external pressure, and the first one-way valve 15 is opened. Due to the installation direction of the second one-way valve 16, the second one-way valve 16 is still in a closed state at this time, and the external air enters the interior of the cylinder 4. We can install a corresponding filtering structure on the intake pipe 13 to prevent external dust and other impurities from entering the interior of the cylinder 4. When the piston 11 moves to After reaching the top, the piston 11 is pushed downward by the electric cylinder 12. At this time, the pressure inside the air cylinder 4 increases, causing the second one-way valve 16 to open. At this time, the first one-way valve 15 is in a closed state. The air inside the air cylinder 4 enters the storage barrel 1 through the air outlet pipe 14, the seamless pipe 17 and the ventilation pipe 5, increasing the pressure inside the storage barrel 1. The internal resin raw material of the storage barrel 1 is discharged from the inside of the discharge pipe 8 and discharged to the inside of the corresponding equipment. The volume of the air pushed into the storage barrel 1 between the front and back differences of the movement of the piston 1 is observed through the scale line 21, so as to judge the amount of resin raw material pushed out of the storage barrel 1. According to people's needs, an appropriate amount of resin raw material is discharged. After taking out an appropriate amount of resin raw material, the electric cylinder 12 is stopped and the first valve 7 and the second valve 9 are closed.

[0040] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
