The control box 2 is installed on the outside of the mixing tank 1 and cooperates with the circulation component 3 and the stirring component 7. The control box 2 is installed with a sound alarm lamp 21. The circulation component 3 comprises a battery 31 and a circulation pump 33. The battery 31 is installed at the lower end of the mixing tank 1 and connected to the control box 2. The circulation pump 33 is installed at the bottom of the mixing tank 1. The processing box 4 is fixedly installed in the mixing tank 1, and a main flow channel 41 and a discharge trough 47 are sequentially opened thereon. The circulation pump 33 is connected to the upper end of the main flow channel 41. A filter plate 42 and an impeller 44 are sequentially arranged in the main flow channel 41. The circulation pump 33 transfers the material The liquid material is pumped into the main channel 41, and then drives the impeller 44 to rotate after passing through the filter plate 42.

When the impeller 44 rotates, it drives the scraper plates 51 to rotate, and the rotating scraper plates 51 push the agglomerated materials filtered out by the filter plate 42 into the crushing trough 46. The crushing component 6 includes a pair of crushing rollers 61, which are installed in the crushing trough 46 and cooperate with the other side of the impeller 44. The impeller 44 synchronously drives the crushing rollers 61 to rotate to crush the agglomerated materials.

[0032] When in use, first add the materials to be mixed into the mixing tank 1. After the materials are loaded, start the stirring component 7 to stir the materials in the mixing tank 1. When a sudden failure or power outage occurs during the stirring process, causing the stirring component 7 to stop stirring, the control box 2 is connected to the battery 31 and starts to use the battery 31 for emergency. The control box 2 controls the components connected to it through the PLC program. After the battery 31 is enabled, the control box 2 controls the sound alarm light 21 to sound an alarm to remind the workshop workers that the stirring component 7 of the equipment has a problem. Failure requires emergency repair. At the same time, the control box 2 starts the circulation pump 33 through the battery 31 to work. The circulation pump 33 extracts materials from the bottom of the mixing tank 1 and injects them into the processing box 4. The materials entering the processing box 4 flow downward along the main channel 41 to the filter plate 42. When a small amount of agglomerates appear in the materials in the mixing tank 1, the filter plate 42 filters out the agglomerates mixed in the materials. Most of the materials continue to flow downward after passing through the filter plate 42 and flush the impeller 44 to rotate. The rotating impeller 44 drives the scraper plate 51 and the crushing roller 6 at the same time. 1 rotates. During this process, the rotating scraper plate 51 pushes the agglomerates and a small part of the materials on the filter plate 42 into the crushing trough 46. The pair of crushing rollers 61 rotate in opposite directions to crush the agglomerates falling into the crushing trough 46. The crushed agglomerate powder is mixed with the materials entering the crushing trough 46. The materials with agglomerate powder flow through the crushing trough 46 toward the discharge trough 47.

At the same time, most of the materials in the main channel 41 flow through the lower end of the main channel 41 and enter the spiral pipe 45.

Subsequently, this part of the material enters the discharge trough 47 through the spiral pipe 45 and merges with the material flowing out of the crushing trough 46, and is discharged from the discharge trough 47 into the mixing tank 1. This cycle continues to mix the entire tank of material, providing sufficient repair time for the workshop workers. When the stirring component 7 can work again, the control box 2 ends the power supply of the battery 31, stops the circulation component 3 from working, and starts the stirring component 7 to work again until the production is completed.

As the scraper plate 51 continues to push, the lumps mixed with a small part of the material eventually fall into the slide 412 and enter the crushing trough 46 along the slide 412. After most of the material passes through the filter plate 42, it converges into the gathering bucket 413. The gathering bucket 413 gathers the material in the main channel 41 and concentrates on flushing the impeller 44 below it, thereby causing the impeller 44 to rotate.

[0036] When the impeller 44 rotates, the driving shaft 441 drives the worm 442 and the driving gear 443 to rotate synchronously.

[0037] The difference from the above embodiment is that the lower end of the main channel 41 is forked to both sides, and the fork on each side is connected to a spiral pipe 45. The spiral pipes 45 on both sides are symmetrically distributed in an arc shape in the processing box 4, and the lower ends of the two spiral pipes 45 are respectively connected to the two sides of the discharge trough 47 corresponding to each other. The spiral pipes 45 are provided with threads, and the lower end of the crushing trough 46 is fixedly connected to the feed pipe 461, and the feed pipe 461 is connected to the upper side of the discharge trough 47.

[0038] Among them, after the material flows into the lower end of the main channel 41, it is divided into two parts through the fork and enters a spiral pipe 45 respectively. The material rotates under the guidance of the inner thread of the spiral pipe 45 and is discharged into the discharge trough 47. The spiral pipes 45 corresponding to the two sides make the materials discharged from the spiral pipes 45 on both sides collide with each other, and are further mixed before being discharged from the discharge trough 47. The material mixed with agglomerated powder in the crushing trough 46 is collected from the top of the discharge trough 47 through the feed pipe 461 to the colliding materials to complete the mixing.

[0039] The difference from the above embodiment is that the feeding assembly 5 also includes a fixing ring 52 and a transmission shaft 53, one end of the scraper plate 51 is fixedly connected to the outside of the fixing ring 52, and a plurality of scraper plates 51 are evenly distributed in a circular shape on the fixing ring 52, the transmission shaft 53 is rotatably installed in the processing box 4, and its upper end is located in the scraper groove 411, the fixing ring 52 is coaxially fixedly connected to the upper end of the transmission shaft 53, the upper and lower ends of the scraper plate 51 are respectively attached to the top and bottom of the scraper groove 411, and the lower end of the transmission shaft 53 is coaxially fixedly connected with a turbine 54, and the turbine 54 is fitted on one side of the worm 442.

[0040] When the worm 442 rotates, the transmission shaft 53 is driven to rotate through the turbine 54 , and the rotating transmission shaft 53 drives the scraper plate 51 on the fixed ring 52 to rotate.

[0041] The difference from the above embodiment is that one end of the two crushing rollers 61 is coaxially fixedly connected with a driven gear 62, the driven gears 62 on the two crushing rollers 61 are meshed with each other, and the driven gear 62 on the crushing roller 61 close to the main channel 41 is also meshed with the lower end of the driving gear 443.

[0042] When the driving gear 443 rotates, it drives the driven gear 62 meshing with it. While driving the crushing roller 61 on it to rotate, the driven gear 62 synchronously drives another driven gear 62 meshing with it to rotate in the opposite direction, thereby driving the other crushing roller 61 to rotate in the same direction, and crushing the lumps that fall into the crushing groove 46.

[0043] The difference from the above embodiment is that a feed port 11 is provided at the upper end of the mixing tank 1, and the feed port 11 is located on one side of the stirring assembly 7.

[0044] During loading, the materials enter the mixing tank 1 from the feed port 11 , and after production is completed, the mixed materials are discharged from the mixing tank 1 by opening the discharge valve 13 .

[0045] The difference from the above embodiment is that the circulation component 3 also includes a solenoid valve 32 and a circulation pipe 34. The solenoid valve 32 is fixedly installed at the bottom of the mixing tank 1, located on one side of the discharge valve 13. The solenoid valve 32 is connected to one end of the circulation pump 33.

The solenoid valve 32 and the circulation pump 33 are both connected to the control box 2 through electrical signals, and the battery 31 is fixedly installed in the battery slot 12.

[0046] Among them, after the control box 2 activates the battery 31, the control box 2 first opens the solenoid valve 32 to enable the circulation pump 33 to extract the material in the mixing tank 1, and then starts the circulation pump 33. The started circulation pump 33 pumps the material at the bottom of the mixing tank 1 into the main channel 41 through the circulation pipe 34. When the equipment is put into use, the battery slot 12 protects the battery 31 and prevents the battery 31 from being damaged.

[0047] The difference from the above embodiment is that the stirring assembly 7 includes a stirring motor 71, a stirring shaft 72 and a stirring paddle 73. The stirring motor 71 is fixedly installed on the top of the mixing tank 1 and is connected to the control box 2 through an electrical signal.

During this process, the stirring motor 71 maintains connection with the control box 2 through electrical signals. When the stirring motor 71 suddenly stops due to a fault, the electrical signal between the stirring motor 71 and the control box 2 is disconnected, so that the control box 2 activates the battery 31 for emergency.

[0049] The invention discloses a furan resin preparation process based on shutdown anti-caking, and uses a mixing preparation device.

[0050] Working principle: When in use, first add the material to be mixed into the mixing tank 1 from the feeding port 11. After the loading is completed, start the stirring motor 71 of the stirring assembly 7. The stirring motor 71 drives the stirring shaft 72 to rotate. The rotating stirring shaft 72 stirs the material in the mixing tank 1 through the stirring paddle 73 to mix it. During this process, the stirring motor 71 is connected to the control box 2 through an electrical signal. When a sudden fault or power failure occurs during the stirring process, causing the stirring motor 71 to stop rotating, the electrical signal between the stirring motor 71 and the control box 2 is disconnected, so that the control box 2 is connected to the battery 31. , the battery 31 is used for emergency, wherein the control box 2 controls the components connected thereto through the PLC program. After the battery 31 is enabled, the control box 2 controls the sound alarm lamp 21 to sound an alarm, reminding the workshop workers that the stirring assembly 7 of the equipment has a fault and needs to be repaired. At the same time, the control box 2 opens the solenoid valve 32, so that the circulation pump 33 can extract the material in the mixing tank 1, and then the circulation pump 33 is started again. The started circulation pump 33 pumps the material at the bottom of the mixing tank 1 into the main flow channel 41 through the circulation pipe 34, and the material flows downward along the main flow channel 41 to the filter plate 42;

[0051] When a small amount of agglomerates appear in the material in the mixing tank 1, the filter plate 42 filters out the agglomerates mixed in the material, and most of the material continues to flow downward after passing through the filter plate 42. The gathering bucket 413 gathers the material in the main channel 41 and intensively flushes the impeller 44 below it, thereby causing the impeller 44 to rotate. When the impeller 44 rotates, the driving shaft 441 drives the worm 442 and the driving gear 443 to rotate synchronously. In this process, the rotating worm 442 drives the transmission shaft 53 to rotate through the turbine 54, and the transmission shaft 53 drives the scraper plate 51 on the fixed ring 52 to rotate, pushing the agglomerates and a small amount of material on the filter plate 42 into the crushing tank 46. The driving gear 443 drives a pair of crushing rollers 61 to rotate in opposite directions to crush the agglomerates falling into the crushing tank 46. The crushed agglomerated powder is mixed with the material entering the crushing tank 46 together, and this part of the material with agglomerated powder passes through the powder The feed pipe 461 under the crushing trough 46 flows toward the discharge trough 47, and the agglomerated powder is integrated into the material in this process. At the same time, when most of the material in the main channel 41 flows through the lower end of the main channel 41, it is divided into two parts through the fork and enters a spiral pipe 45 respectively. The material rotates under the guidance of the inner thread of the spiral pipe 45 and is discharged into the discharge trough 47. The corresponding spiral pipes 45 on both sides make the materials discharged from the spiral pipes 45 on both sides collide with each other, and then are discharged from the discharge trough 47 into the mixing tank 1 after further mixing. This cycle allows the whole tank of material to continue to be mixed, providing sufficient repair time for the workshop workers. When the stirring component 7 can work again, the control box 2 ends the power supply of the battery 31, so that the circulation component 3 ends work, and starts the stirring component 7 to work again until the production is completed. After the production is completed, the mixed material is discharged from the mixing tank 1 by opening the discharge valve 13.
