Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically a reaction device for polyamide wax micro powder. Background Technology

[0002] Traditional methods for producing polyamide wax micronized powder often employ batch reactors, involving heating, stirring, and reaction steps to synthesize and micronize the polyamide wax. However, batch reactors suffer from low production efficiency, high energy consumption, and inconsistent batch-to-batch quality. Furthermore, fluctuations in parameters such as temperature and pressure during the reaction process can easily lead to uneven product quality, thus affecting its performance in downstream applications.

[0003] The reference patent is titled "A Reaction Apparatus for Polyamide Wax Micropowder" (Publication No. CN210058259U, Application Date 2019-05-17). This reaction apparatus for polyamide wax micropowder, by setting up a grinding base and a grinding screen, and a grinding head at the bottom of the stirring rod, can effectively control the particle size of the prepared powder by adjusting the stirring and grinding speed during the powder preparation reaction process. The grinding screen in the grinding base can act as a filter to obtain powder particles of a certain size, thus solving the problem of difficulty in controlling the accuracy of preparing powders of different particle sizes in traditional polyamide wax micropowder reaction apparatuses.

[0004] Based on the above patent, in specific applications, the polyamide wax powder is filtered through the grinding mesh in the grinding base. Although it can achieve the purpose of screening powders of different particle sizes, the mesh is installed statically, and the mesh is easily clogged by the accumulation of powder during the filtration process. Therefore, this utility model provides a reaction device for polyamide wax powder. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a reaction device for polyamide wax micro powder, which solves the problem that existing reaction devices for polyamide wax micro powder, where the grinding screen is statically installed, easily cause the filter screen pores to become clogged due to powder accumulation during the filtration process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reaction device for polyamide wax micro powder, comprising a feed box, a reaction cylinder interconnected at the lower end of the feed box, and a sieving mechanism provided inside the feed box and the reaction cylinder, the sieving mechanism comprising:

[0007] A sieve plate is installed inside the feed box and is used to filter polyamide wax powder.

[0008] The transmission assembly is located at the lower part of the sieve plate and includes a support rod fixedly installed at the lower end of the sieve plate. The lower end of the support rod is rotatably connected to a movable connecting rod via a shaft block. The other end of the movable connecting rod is rotatably connected to a crankshaft via a double-headed shaft. Rotating rods are welded to both sides of the crankshaft and are rotatably connected to the side walls at both ends of the reaction cylinder.

[0009] Preferably, the sieve plate includes a frame that slides up and down close to the inner wall of the feed box, and a screen is installed on the inner side of the frame.

[0010] Preferably, a stirring paddle is fixed to the outside of the rotating rod, and a discharge valve pipe for discharging polyamide wax powder is provided at the lower end of the reaction cylinder.

[0011] Preferably, an mounting plate is fixed to one side of the outer wall of the feeding box, and a motor is fixedly mounted on the outside of the mounting plate. The motor is connected to a first drive shaft at one end near the feeding box, and the first drive shaft extends into the inside of the feeding box and is rotatably connected thereto. A second drive shaft is rotatably connected inside the feeding box, and the second drive shaft extends to the outside of the feeding box and is rotatably connected to the mounting plate.

[0012] Preferably, a first power wheel is welded onto the first drive shaft, and a second power wheel is connected to the portion of the rotating rod extending to the outside of the reaction cylinder. The first power wheel and the second power wheel are connected by a transmission belt.

[0013] Preferably, grinding rollers are fixed on both the first and second drive shafts, and two sets of meshing gears are welded to the ends of the first and second drive shafts respectively.

[0014] Beneficial effects

[0015] This invention provides a reaction apparatus for polyamide wax micro powder. Compared with the prior art, it has the following advantages:

[0016] (1) The reaction device for polyamide wax micro powder uses a sieve to initially filter the raw material to remove larger particles or impurities. At the same time, the first power wheel on the first drive shaft rotates, which drives the second power wheel on the outside of the rotating rod to rotate through the transmission belt. The rotation of the rotating rod causes the crankshaft and the connected movable connecting rod and support rod to reciprocate, thereby driving the sieve plate to vibrate up and down, enhancing the filtration effect and effectively avoiding the problem of the filter screen mesh being easily blocked by powder accumulation during the filtration process.

[0017] (2) The reaction device for polyamide wax micro powder is driven by a motor to rotate the first drive shaft. The first drive shaft and the second drive shaft rotate synchronously by meshing gears at their ends. The grinding rollers fixed on the two drive shafts grind the polyamide wax micro powder in advance. At the same time, the raw materials are stirred in the reaction cylinder by a stirring paddle, which promotes the chemical reaction or physical mixing in the reaction cylinder and drives the sieve plate to move up and down. The synchronous operation of multiple components is achieved through a single drive source. It has strong functionality and low equipment cost. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4This utility model provides a technical solution: a reaction device for polyamide wax micro powder, including a feed box 1, a reaction cylinder 13 interconnected at the lower end of the feed box 1, a sieving mechanism 2 provided inside the feed box 1 and the reaction cylinder 13, the sieving mechanism 2 including: a sieve plate 21, provided inside the feed box 1 and used for sieving polyamide wax micro powder; a transmission component 22, provided at the lower part of the sieve plate 21, including a support rod 221 fixedly installed at the lower end of the sieve plate 21, and the lower end of the support rod 221 is rotatably connected to a movable connecting rod 222 through a shaft block, and the other end of the movable connecting rod 222 is rotatably connected to a crankshaft 223 through a double-headed shaft, and rotating rods 224 are welded to both sides of the crankshaft 223, the rotating rods 224 being rotatably connected to the side walls at both ends of the reaction cylinder 13.

[0025] In this embodiment, the sieve plate 21 includes a plate frame 211 that slides up and down close to the inner wall of the feed box 1, and a screen 212 is installed on the inner side of the plate frame 211. A stirring paddle 3 is fixed on the outer side of the rotating rod 224, and a discharge valve pipe for discharging polyamide wax micro powder is provided at the lower end of the reaction cylinder 13. The stirring paddle 3 stirs the raw materials in the reaction cylinder 13 to promote the chemical reaction or physical mixing in the reaction cylinder. When the reaction or mixing reaches the predetermined requirements, the discharge valve pipe at the lower end of the reaction cylinder 13 is opened to discharge the processed polyamide wax micro powder.

[0026] In this embodiment, a mounting plate 4 is fixed to one side of the outer wall of the feed box 1, and a motor 5 is fixedly mounted on the outside of the mounting plate 4. The motor 5 is connected to a first drive shaft 6 at one end near the feed box 1, and the first drive shaft 6 extends into the feed box 1 and is rotatably connected thereto. A second drive shaft 7 is rotatably connected inside the feed box 1, and the second drive shaft 7 extends to the outside of the feed box 1 and is rotatably connected to the mounting plate 4. A first power wheel 8 is welded onto the first drive shaft 6, and a second power wheel 9 is connected to the part of the rotating rod 224 that extends to the outside of the reaction cylinder 13. The first power wheel 8 and the second power wheel 9 are connected by a transmission belt 10. The motor 5 outputs power to the first drive shaft 6, and the first power wheel 8 on the first drive shaft 6 rotates accordingly. The second power wheel 9 on the outside of the rotating rod 224 is rotated through the transmission belt 10. The rotation of the rotating rod 224 causes the crankshaft 223 and the movable connecting rod 222 and the support rod 221 connected thereto to reciprocate, thereby driving the screen plate 21 to vibrate up and down.

[0027] In this embodiment, grinding rollers 12 are fixed on both the first drive shaft 6 and the second drive shaft 7, and two sets of meshing gears 11 are welded to the ends of the first drive shaft 6 and the second drive shaft 7 respectively; the first drive shaft 6 and the second drive shaft 7 rotate synchronously by meshing with each other through the gears 11 at their ends, and the grinding rollers 12 fixed on the two drive shafts grind the polyamide wax powder in one step.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, the polyamide wax powder raw material is first added into the feed box 1 through the top opening. The raw material falls between the two sets of grinding rollers 12. When the motor 5 starts, the motor 5 drives the first drive shaft 6 to rotate. The first drive shaft 6 and the second drive shaft 7 rotate synchronously through the meshing of the gears 11 at the ends. The grinding rollers 12 fixed on the two drive shafts grind the polyamide wax powder in advance to ensure the fineness of the raw material.

[0030] Subsequently, the ground raw material falls onto the sieve plate 21, which consists of a plate frame 211 and a screen 212. The plate frame 211 is slidably set up against the inner wall of the feed box 1, while the screen 212 is used to perform preliminary sieving of the raw material to remove larger particles or impurities. At the same time, the first power wheel 8 on the first drive shaft 6 rotates, which drives the second power wheel 9 on the outside of the rotating rod 224 to rotate through the transmission belt 10. The rotation of the rotating rod 224 causes the crankshaft 223 and the connected movable connecting rod 222 and support rod 221 to reciprocate, thereby driving the sieve plate 21 to vibrate up and down, enhancing the sieving effect. The polyamide wax powder that has been sieved and ground falls into the reaction cylinder 13 through the space below the sieve plate 21. The rotating rod 224 not only drives the sieve plate 21 to vibrate, but also stirs the raw material in the reaction cylinder 13 through the stirring paddle 3, promoting the chemical reaction or physical mixing in the reaction cylinder.

[0031] Finally, once the reaction or mixing reaches the predetermined requirements, open the discharge valve at the lower end of the reaction cylinder 13 to discharge the processed polyamide wax powder from the device.
