Technical Field

[0001] The present invention relates to the technical field of phenolic resin production, and specifically relates to a feeding device for phenolic resin production. Background Art

[0002] Phenolic resin is an important chemical raw material, mainly formed by the polycondensation of phenol and formaldehyde under the condition of a catalyst. Due to its excellent properties, phenolic resin has a wide range of applications in multiple fields. With the progress of technology and the improvement of environmental awareness, efforts are currently being made to develop more environmentally friendly phenolic resins and reduce the impact on the environment during the production process. When producing phenolic resin, it is necessary to add production raw materials into the reaction kettle, and the raw materials react in the reaction kettle to generate phenolic resin.

[0003] Currently, when putting the raw materials of phenolic resin, due to the high height of the reaction kettle, it is not convenient for workers to put the raw materials for phenolic resin production, and it is not easy to control the feeding ratio of the raw materials for phenolic resin production. After manual measurement, they need to be put into the reaction kettle one by one, which increases the difficulty of the feeding process and cannot continuously feed automatically according to the appropriate ratio. Therefore, we propose a feeding device for phenolic resin production to solve the above-mentioned problems. Summary of the Invention

[0009] Preferably, the thread distribution directions of the front and rear sections of the bidirectional lead screw are opposite. Moving plates are connected to the sections with opposite thread distribution directions of the bidirectional lead screw. By rotating the bidirectional lead screw, the moving plates are controlled to move in opposite directions simultaneously.

[0010] Preferably, the moving plate is slidably connected to the moving bottom plate. The moving plate penetrates through the upper wall of the moving bottom plate, which can ensure the stable movement of the moving plate and enable the smooth connection between the moving plate and the adjusting plate.

[0011] Preferably, the moving seat has a "hui" - shaped structure. The moving seat is sleeved outside the mounting plate. The moving seat and the mounting plate form a sliding structure, which can limit the moving seat on the mounting plate. By pushing the moving seat with a hydraulic rod and when the mounting plate moves vertically, the moving seat can be driven to drive the conveying housing to move.

[0012] Preferably, the inside of the gas collecting seat is a hollow structure. The air injection holes are equally spaced on the side of the gas collecting seat close to the feeding roller.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-8 , the present invention provides the following technical solutions: A phenolic resin production feeding device includes a moving bottom plate 1. Moving rollers 2 are installed on the lower side of the moving bottom plate 1. A servo motor 3 is installed at the front end of the moving bottom plate 1. The output end of the servo motor 3 is connected to a bi-directional lead screw 4. The outside of the bi-directional lead screw 4 is threadedly connected to a moving plate 5. The upper end of the moving plate 5 is hinged to an adjusting plate 6. The upper end of the adjusting plate 6 is hinged to a mounting plate 7;

[0031] Further, the thread distribution directions of the front and rear sections of the bi-directional lead screw 4 are opposite. Moving plates 5 are connected to both sections of the bi-directional lead screw 4 with opposite thread distribution directions. By rotating the bi-directional lead screw 4, the moving plates 5 are controlled to move in opposite directions simultaneously;

[0032] Further, the moving plate 5 is slidably connected to the moving bottom plate 1. The moving plate 5 penetrates the upper wall of the moving bottom plate 1, which can ensure the stable movement of the moving plate 5 and enable the smooth connection between the moving plate 5 and the adjusting plate 6;

[0033] A hydraulic rod 8 is installed above the mounting plate 7. The output end of the hydraulic rod 8 is connected to a moving seat 9. The upper end of the moving seat 9 is installed with a conveyor housing 10. A feeding housing 15 is bolted and fixed above the conveyor housing 10. The lower end of the conveyor housing 10 is communicated with a discharge pipe 21;

[0034] Further, the moving seat 9 has a "return" shape structure. The moving seat 9 is sleeved outside the mounting plate 7. The moving seat 9 and the mounting plate 7 form a sliding structure, which can limit the moving seat 9 on the mounting plate 7. The moving seat 9 is pushed to move by the hydraulic rod 8. And when the mounting plate 7 moves vertically, it can drive the moving seat 9 to drive the conveyor housing 10 to move;

[0035] Further, a gas collecting seat 13 is installed on the inner wall of the conveying housing 10. An air injection hole 14 is formed on the side surface of the gas collecting seat 13. A blower 11 is installed on the outer wall of the conveying housing 10. The air outlet of the blower 11 is communicated with an air delivery pipe 12. One end of the air delivery pipe 12 is communicated with the gas collecting seat 13;

[0036] Furthermore, the inside of the gas collecting seat 13 is of a hollow structure. The air injection holes 14 are evenly distributed on one side of the gas collecting seat 13 close to the feeding roller 19, so that the gas can be concentrated in the gas collecting seat 13 and ejected from the air injection holes 14 to clean the feeding tank 20;

[0037] A storage tank 16 is formed inside the feeding housing 15. A driving motor 17 is installed to the right of the storage tank 16. The output end of the driving motor 17 is connected to a rotating shaft 18. A feeding roller 19 is installed at the end of the rotating shaft 18. A feeding groove 20 is formed on the side surface of the feeding roller 19;

[0038] Further, the inner wall of the storage tank 16 is inclined. The position of the storage tank 16 corresponds to the position of the feeding groove 20, so that the materials in the storage tank 16 can smoothly enter the feeding groove 20 and the materials can be put into the reaction kettle in equal proportion;

[0039] Further, the lowest point of the feeding roller 19 is lower than the lowest point of the feeding housing 15. The contact part between the feeding housing 15 and the feeding roller 19 is arc-shaped, which is convenient for the feeding roller 19 to block the storage tank 16, so that the materials can enter the reaction kettle quantitatively;

[0040] Further, the inner wall of the feeding groove 20 is smooth, and the inner wall corners of the feeding groove 20 are arc-shaped, which is convenient for cleaning the feeding groove 20 and avoiding the retention of materials at the corners of the feeding groove 20;

[0041] Specifically, when the phenolic resin production feeding device is used, the moving base plate 1 is pushed to make the moving roller 2 installed under the moving base plate 1 roll, and the moving base plate 1 is moved to the side of the reaction kettle, and the raw materials for phenolic resin production are stored in the storage tank 16 respectively, and the servo motor 3 is powered on to control the servo motor 3 to rotate forward, thereby controlling the bidirectional screw rod 4 connected to the output end of the servo motor 3 to rotate, and the front and rear sections of the bidirectional screw rod 4 have opposite thread distribution directions, and the sections with opposite thread distribution directions of the bidirectional screw rod 4 are connected to the moving plates 5, so that the bidirectional screw rod 4 drives the moving plates 5 connected to the outer threads to move relatively, and the moving plates 5 slide in the moving base plate 1 to ensure the moving The plate 5 moves stably. When the movable plate 5 moves, it can synchronously drive the upper hinged adjustment plate 6 to rotate. The adjustment plate 6 pushes the upper hinged mounting plate 7 to move upward. The mounting plate 7 drives the outer sleeve movable seat 9 to move upward, so that the movable seat 9 drives the upper connected feeding shell 15 and the conveying shell 10 to move upward, and the conveying shell 10 is moved to the top of the reactor. Then, the hydraulic rod 8 is opened to push the movable seat 9 connected to the output end to move. The movable seat 9 slides on the mounting plate 7, so that the movable seat 9 drives the conveying shell 10 and the feeding shell 15 to move in the direction close to the reactor, and the lower feeding pipe 21 connected to the lower end of the conveying shell 10 is opposite to the feed port of the reactor.

[0042] The position of the storage trough 16 corresponds to the position of the feeding trough 20, and the capacities of the three groups of feeding troughs 20 are distributed according to the appropriate proportion of the phenolic resin feeding raw materials. The phenolic resin raw materials in the storage trough 16 fall into the feeding trough 20 at the corresponding position, and the driving motor 17 is powered on. The driving motor 17 controls the rotation of the rotating shaft 18 connected to the output end, so that the rotating shaft 18 controls the rotation of the feeding roller 19. When the position of the feeding trough 20 opened on the side of the feeding roller 19 is staggered with the position of the storage trough 16, the remaining surface of the feeding roller 19 blocks the bottom of the storage trough 16 to prevent the phenolic resin production raw materials in the storage trough 16 from continuing to fall. With the rotation of the feeding roller 19, the raw materials in the feeding trough 20 can be concentrated in the conveying shell 10, and then The phenolic resin raw material in the storage tank 16 continues to fall into the feeding tank 20 at the corresponding position. With the rotation of the feeding roller 19, the phenolic resin raw material can be continuously added to the reactor, and the phenolic resin raw material is added in a quantitative ratio. In order to prevent the powdery material from adhering to the feeding tank 20, the hair dryer 11 can be powered on, and the hair dryer 11 is transported into the air pipe 12, and then the wind is concentrated into the air collecting seat 13, and finally ejected from the air jet hole 14 opened on the side of the air collecting seat 13. When the feeding tank 20 rotates to the air jet hole 14, the feeding tank 20 can be blown to clean it, so that all the phenolic resin raw materials fall into the reactor.

[0043] After the feeding is completed, the hydraulic rod 8 can be controlled to drive the moving seat 9 to move left, thereby driving the feeding shell 15 and the conveying shell 10 to move left and reset, and the positions of the feeding shell 15 and the conveying shell 10 are staggered with the position of the reactor, and then the servo motor 3 is controlled to reverse, so that the servo motor 3 controls the bidirectional screw rod 4 to reverse, and the bidirectional screw rod 4 drives the moving plates 5 connected to the outer thread to move away from each other, and the moving plate 5 pulls the adjusting plate 6, so that the adjusting plate 6 pulls the mounting plate 7 downward, so that the position of the feeding shell 15 and the conveying shell 10 is lowered, which is convenient for the staff to store the materials in the storage trough 16 and continue to feed, reducing the labor intensity of the staff, and the feeding shell 15 and the conveying shell 10 are fixed by bolts, which can be disassembled for easy cleaning and maintenance.
