Description

Technical Field

[0001] This utility model belongs to the field of phenolic resin production technology, and in particular relates to a safe dripping device for the production of phenolic resin. Background Technology

[0002] A dripping device for phenolic resin production is a specialized piece of equipment used to precisely and continuously add raw materials or catalysts such as phenol and formaldehyde to the reaction system at a specific rate and dosage during the synthesis reaction of phenolic resin. It typically consists of a storage tank, a metering pump, dripping pipelines, valves, and a control system. Dripping devices are used in phenolic resin production because the phenolic condensation reaction is sensitive to the ratio of raw materials, the rate of addition, and the reaction temperature. If the raw materials are added all at once, it can easily lead to excessively high local concentrations, intense exothermic reactions, increased side reactions, and uneven distribution of resin molecular weight. A dripping device ensures a stable supply of raw materials, precise control of the reaction process, and a gentle and orderly reaction, thereby guaranteeing the structural stability and product quality of the phenolic resin.

[0003] However, existing phenolic resin dripping devices can only be matched with reactors of specific sizes. When production needs change and reactors of different specifications need to be replaced, the devices are difficult to adapt to and use properly. This will force the production process to be interrupted, increase the time cost of equipment replacement and debugging, and thus restrict the flexibility and adaptability of the devices. Utility Model Content

[0004] The purpose of this invention is to provide a safe dripping device for the production of phenolic resin. By setting up a clamping part, it solves the problem that the device can only be matched with a reactor of a specific size, which makes it difficult to adapt and use normally when production needs change and a reactor of a different specification needs to be replaced. This will lead to the forced interruption of the production process, increase the time cost of equipment replacement and debugging, and thus restrict the flexibility and adaptability of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a safe dripping device for the production of phenolic resin, comprising a slide plate, and further comprising: a clamping part disposed on the slide plate; a lifting part disposed at the bottom of the slide plate; the clamping part comprising a clamping assembly disposed at the top of the slide plate; a dripping assembly disposed at the top of the slide plate; and a stirring assembly disposed on the clamping part. The clamping assembly comprises two clamps rotatably connected to the top of the slide plate. A groove is provided on the top of the slide plate, and a T-shaped slider is slidably connected within the groove. The left and right sides of the T-shaped slider are in contact with the two clamps. A driving component is provided on the back of the slide plate, wherein the two clamps are symmetrically distributed on both sides of the T-shaped slider.

[0006] Furthermore, the lifting unit includes a lifting assembly installed at the bottom of the skateboard, and a drive assembly installed on the lifting assembly, wherein the lifting assembly is used in conjunction with the drive assembly.

[0007] Furthermore, the dripping assembly includes a base plate disposed at the bottom of the slide plate, a slide rod assembly fixedly connected to the top of the base plate, a top plate fixedly connected to the top of the slide rod assembly, a hoop fixedly connected to the top of the top plate, a dripping tank fitted inside the hoop, and a solenoid valve disposed on the dripping tank. The bottom end of the dripping tank extends beyond the top plate. The base plate, slide rod assembly, and top plate form a stable support structure. The hoop can stably fix the dripping tank. The solenoid valve can accurately control the dripping amount and rate. The extension of the bottom end of the dripping tank beyond the top plate facilitates the dripping of materials into the target container, thereby improving the stability, accuracy, and ease of operation of the dripping process.

[0008] Furthermore, the stirring assembly includes a reaction vessel disposed on the inner walls of two clamps, a motor sleeve fixedly connected to the top of the reaction vessel, a motor sleeve fitted on the motor sleeve, a rotating shaft fixedly connected to the output shaft of the motor via a coupling, stirring blades fitted on the outer wall of the rotating shaft, a connecting pipe fixedly connected to the top of the reaction vessel, the connecting pipe being inserted into a dropping tank, and a sealing element provided on the connecting pipe, wherein the rotating shaft passes through the reaction vessel and is rotatably connected to the reaction vessel.

[0009] Furthermore, the lifting assembly includes a slide rail fixedly connected to the top of the base plate, a rack slidably connected to the outer surface of the slide rail, a U-shaped frame fixedly connected to the top of the base plate, a rotating rod rotatably connected to the U-shaped frame, a gear sleeved on the outer wall of the rear end of the rotating rod, the gear meshing with the rack, and a transmission component provided on the outer wall of the rotating rod. The rear end of the rotating rod extends beyond the U-shaped frame, and the slide rail provides guiding support for the rack's sliding, ensuring smooth lifting. The gear and rack meshing transmission is precise and reliable. Combined with the U-shaped frame's stable limiting of the rotating rod, the rack can be stably lifted and lowered by driving the rotating rod through the transmission component. The structure is compact and has high transmission efficiency, improving the accuracy and operability of the assembly's lifting and adjusting capabilities.

[0010] Furthermore, the drive assembly includes a rectangular plate two fixedly connected to the top of the base plate. A hydraulic push rod two is fixedly connected to the left side of the rectangular plate two, and the output end of the hydraulic push rod two extends out of the rectangular plate two and is slidably connected to the rectangular plate two. A connecting plate is fixedly connected to the left side of the rack, and the output end of the hydraulic push rod two is fixedly connected to the connecting plate. The hydraulic push rod two is located on the left side of the rack and provides stable power. It directly drives the rack to move through the connecting plate. The power transmission is direct and efficient. The hydraulic drive method facilitates precise control of the rack's movement speed and stroke. Combined with the limiting support of the rectangular plate two, it ensures a smooth and reliable driving process and improves the controllability and stability of the rack's lifting and lowering adjustment.

[0011] Furthermore, the sealing element includes a sealing groove formed at the top of the connecting pipe, and a sealing ring is provided at the bottom of the dripping tank. The bottom of the sealing ring extends into the sealing groove. The fitting design of the sealing ring and the sealing groove can tightly fill the gap at the connection between the connecting pipe and the dripping tank, effectively preventing material leakage during the dripping process. At the same time, it prevents external air or impurities from entering the pipeline and affecting the purity of the material, ensuring the sealing and safety of the dripping process, and improving the reliability of equipment operation.

[0012] Furthermore, the transmission component includes a connecting rod 1 sleeved on the outer wall of the rotating rod, a connecting rod 2 hinged to the end of the connecting rod 1 away from the rotating rod, and a fixing block hinged to the end of the connecting rod 2 away from the connecting rod 1. The top of the fixing block is fixedly connected to the sliding plate; wherein, the top of the fixing block has an opening.

[0013] This utility model has the following beneficial effects: 1. By setting up a clamping part, when using this device, the reactor is first placed between two clamps. The hydraulic pusher is activated to push the T-shaped slider to apply an external force to one end of the clamp, so that the other end of the clamp compresses the telescopic rod and spring to accumulate elastic potential energy to clamp the reactor. When the compression is released, the telescopic rod and spring release potential energy to push the clamp to unfold, making it easy to put in reactors of different sizes. This setting can meet the adaptation requirements of reactors of different sizes and the dripping device, effectively improving the flexibility and adaptability of the device. 2. By setting up a lifting unit, after the reactor is fixed, the hydraulic push rod 2 is activated to push the rack connecting plate, causing the rack to move to the right along the slide rail. Through the meshing transmission of the rack and gear, the rotating rod drives the connecting rod assembly, causing the slide plate to carry the reactor upward along the slide rod assembly. This achieves precise insertion between the reactor connecting pipe and the lower interface of the dripping tank, and the sealing groove of the connecting pipe matches the sealing ring of the dripping tank to prevent leakage. This setting can greatly simplify the pipeline connection process and significantly improve work efficiency. At the same time, with the help of the closed conveying method, it can not only eliminate the problem of raw material leakage, but also avoid direct contact between personnel and raw materials, thus fully ensuring the safety of the feeding process.

[0021] The lifting unit 3 includes a lifting assembly 31, which is installed at the bottom of the slide plate 1; and a drive assembly 32, which is installed on the lifting assembly 31.

A rack 312 is slidably connected to the outer surface of the slide rail 311. A U-shaped frame 313 is fixedly connected to the top of the base plate 221.

Gear 315 meshes with rack 312; a transmission component is provided on the outer wall of rotating rod 314; the rear end of rotating rod 314 extends outside U-shaped frame 313; drive assembly 32 includes a rectangular plate 321 fixedly connected to the top of base plate 221; a hydraulic push rod 322 is fixedly connected to the left side of rectangular plate 321; the output end of hydraulic push rod 322 extends outside rectangular plate 321 and is slidably connected to rectangular plate 321; a connecting plate 323 is fixedly connected to the left side of rack 312; and hydraulic push rod 322... The output end of 2 is fixedly connected to the connecting plate 323; wherein, the hydraulic push rod 2 322 is located on the left side of the rack 312, and the transmission component includes a connecting rod 1 316 sleeved on the outer wall of the rotating rod 314, a connecting rod 2 317 hinged to the end of the connecting rod 1 316 away from the rotating rod 314, and a fixing block 318 hinged to the end of the connecting rod 2 317 away from the connecting rod 1 316, the top of the fixing block 318 being fixedly connected to the slide plate 1; wherein, the top of the fixing block 318 is provided with a notch, and by setting the lifting part 3, after the reactor is fixed, the starting liquid... The push rod pushes the rack connecting plate, causing the rack to move to the right along the slide rail. Through the meshing transmission of the rack and gear, the rotating rod drives the connecting rod assembly, causing the slide plate to carry the reactor upward along the slide rod assembly. This achieves precise insertion of the reactor connecting pipe into the lower interface of the dripping tank, and the sealing groove of the connecting pipe matches the sealing ring of the dripping tank to prevent leakage. This setting can greatly simplify the pipeline connection process and significantly improve work efficiency. At the same time, with the help of the closed conveying method, it can not only eliminate the problem of raw material leakage, but also avoid direct contact between personnel and raw materials, thus fully ensuring the safety of the feeding process.

[0022] One specific application of this embodiment is the solenoid valve 227 used in the dripping device: it is an automated component used to control the on / off state and flow rate of the dripping liquid. It drives the valve core to move through electromagnetic force, thereby achieving precise control of the liquid dripping rate and amount. It is commonly used in liquid dripping scenarios in chemical, pharmaceutical, and laboratory fields. Here are some recommended models: SMCS070M-6DC-32: ultra-compact design, only 7mm wide and weighing only 5g, suitable for space-constrained occasions, coil power consumption 0.5W, maximum operating pressure 0.5MPa, adopts elastic sealing and internal pilot design, and is suitable for various industrial automation fields such as microfluidic control systems.

[0023] When using this device, the reactor 231 can be placed between the two clamps 211. Then, the hydraulic push rod 215 is activated. The hydraulic push rod 215 pushes the T-shaped slider 213, applying outward squeezing force to one end of the two clamps 211 that are rotatably connected to the slide plate 1. At this time, the other end of the two clamps 211 will compress the internal telescopic rod 216 and spring 217, causing the spring 217 and telescopic rod 216 to accumulate elastic potential energy, thereby clamping the reactor 231. When the T-shaped slider 213 releases the squeezing of the two clamps 211, the telescopic rod 216 and spring 217 will release elastic potential energy, pushing the two clamps 211 to unfold each other, making it easy to put in reactors 231 of different sizes. This setting can meet the adaptation requirements of reactors 231 of different sizes and the dripping device, significantly improving the flexibility and adaptability of the device.

[0024] After the reactor 231 is fixed, the hydraulic push rod 322 is activated, which pushes the connecting plate 323 on the rack 312, causing the rack 312 to move smoothly to the right along the slide rail 311. Since the rack 312 meshes with the gear 315 on the rotating rod 314 rotatably mounted inside the U-shaped frame 313, during the movement of the rack 312, the rotating rod 314 drives the connecting rod 316 through the meshing transmission with the gear 315. This, along with the connecting rod 317 and the fixing block 318, allows the rack to slide smoothly onto the slide rod assembly 222. The sliding plate 1 can drive the reactor 231 to move upward, ultimately achieving precise insertion of the connecting pipe 236 on the reactor 231 into the lower interface of the dropping tank 225. At the same time, the sealing groove 237 on the connecting pipe 236 will match the sealing ring 238 on the dropping tank 225, effectively preventing leakage. This setting greatly simplifies the pipeline connection process and significantly improves work efficiency. In addition, with the help of the closed conveying method, it can not only eliminate the problem of raw material leakage, but also avoid direct contact between personnel and raw materials, thus fully ensuring the safety of the feeding process. After the pipeline connection is completed, the solenoid valve 227 on the drip tank 225 will precisely control the material to be added into the reaction vessel 231 according to the preset program. After the material enters the reaction vessel 231, the motor 233 is started. The motor 233 drives the stirring blade 235 through the rotating shaft 234 to fully stir the material, accelerate the material reaction rate, and ensure that the reaction is fully and efficiently carried out.
