Description

Technical Field

[0001] This utility model belongs to the field of 3D printing material preparation technology, and in particular relates to a 3D printing slurry reaction vessel. Background Technology

[0002] 3D printing technology, as an advanced additive manufacturing technology, has developed rapidly in recent years. In the 3D printing process, the slurry is an important printing material, and its quality and performance directly affect the quality of the final printed product. The 3D printing slurry reactor is a key piece of equipment used to prepare and process 3D printing slurry. It can mix, stir and react various raw materials to obtain slurry that meets specific 3D printing needs.

[0003] Existing 3D printing slurry reactors lack temperature control. The reaction process of 3D printing slurry often has strict temperature requirements. Different slurry components and reaction types require specific temperature conditions to react smoothly and ensure that the slurry performance meets the requirements of 3D printing. For example, some slurries containing heat-sensitive additives may decompose and become ineffective if the temperature is too high during the reaction, leading to a decrease in slurry performance. On the other hand, if the temperature is too low, the reaction rate will slow down or may not be able to react completely, which will also affect the quality of the slurry.

[0004] To address these issues, we provide a 3D-printed slurry reactor. Utility Model Content

[0005] The purpose of this invention is to provide a 3D printing slurry reactor. By combining a temperature control component and a stirring component, it solves the problem that existing 3D printing slurry reactors lack temperature control, which leads to a slower reaction rate of the printing slurry or even prevents complete reaction, thus affecting the quality of the slurry.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a 3D printing slurry reaction vessel, comprising a vessel body, a fixed plate fixedly connected to the bottom of the vessel body surface, a temperature control component disposed on one side of the top of the fixed plate, a cavity opened at the top of the vessel body, a top cover disposed at the top of the vessel body, a stirring component disposed at the bottom of the top cover, the temperature control component comprising an air-cooled box, the bottom of the air-cooled box being fixedly connected to the top of the fixed plate, a frame fixedly connected to one side of the air-cooled box, a fan disposed in the inner cavity of the frame, a hot air box fixedly connected to the top of one side of the frame, coils disposed in the inner cavities of both the air-cooled box and the hot air box, cooling plates disposed on both sides of the inner cavity of the air-cooled box, and heating plates disposed on both sides of the inner cavity of the hot air box, a ventilation duct connected to one side of the fan via a ventilation pipe, the top and bottom of the ventilation duct being connected to the air-cooled box and the hot air box via connecting pipes.

[0008] The present invention is further configured such that the stirring assembly includes a stirring motor, the stirring motor is disposed on the top of the top cover, the output end of the stirring motor is fixedly connected to a stirring rod, the surface of the stirring rod is fixedly connected to a stirring frame, and the end of the stirring frame away from the stirring rod is fixedly connected to a scraper. When the stirring motor is turned on, the output end of the stirring motor drives the stirring rod to rotate, the stirring rod drives the stirring frame on its surface to rotate, and the stirring frame drives the scraper to rotate, thereby scraping and cleaning the inner wall of the vessel while stirring the material.

[0009] The present invention is further configured such that a sealing ring is fixedly connected to the bottom of the top cover, the surface of the sealing ring is movably connected to the inner cavity of the cavity, and the sealing ring is inserted into the inner cavity of the cavity as the top cover is fixed to the top of the vessel body, thereby improving the sealing performance of the connection between the top cover and the vessel body.

[0010] The present invention is further configured such that a connecting rod is fixedly connected to the bottom of the surface of the stirring rod, and an arc-shaped scraper is fixedly connected to the end of the connecting rod away from the stirring rod. The arc-shaped scraper moves at the bottom of the inner wall of the vessel as the stirring rod rotates, cleaning away the material attached to the bottom of the inner wall of the vessel, thereby further preventing material residue in the inner cavity of the vessel.

[0011] The present invention is further configured such that support frames are fixedly connected to both sides of the bottom of the fixed plate, and support pads are fixedly connected to the bottom of the support frames. The support pads can improve the friction of the bottom of the support frames. The bottom of the reactor body is stably supported by the two anti-slip support frames, so that the reactor can be stably placed in the designated use position.

[0012] The present invention is further configured such that a temperature sensor is provided on one side of the bottom of the top cover, and a display is provided on the top of one side of the frame.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model monitors the internal temperature of the reactor in real time using a temperature sensor. When the temperature exceeds the set range, it can automatically switch between cooling and heating modes. When the temperature is higher than the set value, the cooling element and the fan work together to cool the air through the coil and then introduce it into the cavity to lower the internal temperature of the reactor. When the temperature is lower than the set value, the heating plate and the fan work together to heat the air and then send it into the cavity to raise the temperature, thereby accurately controlling the internal temperature of the reactor to maintain it within the set range and providing a stable temperature environment for the 3D printing slurry reaction.

[0017] 2. This utility model uses a stirring motor to drive the stirring rod, stirring frame and scraper to rotate. While fully stirring the material in the reactor, the scraper can be used to scrape and clean the inner wall of the reactor, effectively avoiding the residue and waste caused by the material adhering to the inner wall. This not only improves the uniformity of material stirring and reaction efficiency, but also reduces the amount of manual cleaning work. Attached Figure Description

[0027] Example 1

[0028] Please see Figure 1-6 This utility model relates to a 3D printing slurry reaction vessel, comprising a vessel body 1, a fixed plate 2 fixedly connected to the bottom of the surface of the vessel body 1, a temperature control component 3 disposed on one side of the top of the fixed plate 2, a cavity opened in the top of the vessel body 1, a top cover 4 disposed on the top of the vessel body 1, a stirring component 5 disposed at the bottom of the top cover 4, and a cooling box 301 comprising an air-cooled box 301, the bottom of the air-cooled box 301 being fixedly connected to the top of the fixed plate 2, and a frame 302 fixedly connected to one side of the air-cooled box 301. The inner cavity is equipped with a fan 303. A hot air box 304 is fixedly connected to the top of one side of the frame 302. The inner cavities of the air-cooled box 301 and the hot air box 304 are both equipped with coils 305. Cooling plates 306 are installed on both sides of the inner cavity of the air-cooled box 301. Electric heating plates 307 are installed on both sides of the inner cavity of the hot air box 304. A ventilation duct 308 is connected to one side of the fan 303 through a ventilation pipe. The top and bottom of the ventilation duct 308 are connected to the air-cooled box 301 and the hot air box 304 through connecting pipes.

[0029] Specifically: When the cooling plates 306 are turned on, the two cooling plates 306 are powered on and run, which lowers the temperature of the inner cavity of the air-cooled box 301 and the surface of the coil 305. The fan 303 runs and draws outside air into the inner cavity of the coil 305. The gas is cooled as it flows through the curved inner cavity of the coil 305. The cooled gas enters the cavity and lowers the temperature of the inner cavity of the vessel body 1. Similarly, when the heating plates 307 are turned on, the two heating plates 307 are powered on and run, which raises the temperature of the inner cavity of the hot air box 304 and the surface of the coil 305. When the air valve leading to the inner cavity of the air-cooled box 301 is closed, the fan 303 runs and draws outside air into the inner cavity of the hot air box 304. The gas is heated as it flows through the inner cavity of the coil 305. The hot air enters the cavity and raises the temperature of the inner cavity of the vessel body 1.

[0030] Example 2

[0031] Please see Figure 1-6 Based on Embodiment 1, the stirring assembly 5 includes a stirring motor 501, which is located on the top of the top cover 4. A stirring rod 502 is fixedly connected to the output end of the stirring motor 501. A stirring frame 503 is fixedly connected to the surface of the stirring rod 502. A scraper 504 is fixedly connected to the end of the stirring frame 503 away from the stirring rod 502. A sealing ring is fixedly connected to the bottom of the top cover 4. The surface of the sealing ring is movably connected to the inner cavity of the cavity. A connecting rod is fixedly connected to the bottom of the surface of the stirring rod 502. An arc-shaped scraper is fixedly connected to the end of the connecting rod away from the stirring rod 502. Support frames 6 are fixedly connected to both sides of the bottom of the fixed plate 2. A support pad is fixedly connected to the bottom of the support frame 6. A temperature sensor 7 is provided on one side of the bottom of the top cover 4. A display 8 is provided on the top of one side of the frame 302. A feeding hopper is provided on one side of the top of the top cover 4. A discharge port is provided at the bottom of the vessel body 1. An exhaust pipe is provided on the top of one side of the vessel body 1. A solenoid valve is provided inside the exhaust pipe.

[0032] Specifically: The stirring motor 501 is turned on, and its output drives the stirring rod 502 to rotate. The stirring rod 502 drives the stirring frame 503 on its surface to rotate, and the stirring frame 503 drives the scraper 504 to rotate. While stirring the material, the inner wall of the vessel 1 is scraped and cleaned. The sealing ring, along with the top cover 4 fixed to the top of the vessel 1, is inserted into the inner cavity of the cavity, thereby improving the sealing between the top cover 4 and the vessel 1. The arc-shaped scraper moves along the bottom of the inner wall of the vessel 1 as the stirring rod 502 rotates, cleaning away the material adhering to the bottom of the inner wall of the vessel 1, achieving the desired cleaning effect. To prevent material residue from remaining in the inner cavity of the reactor body 1, the support pad increases the friction at the bottom of the support frame 6. The two anti-slip support frames 6 provide stable support for the bottom of the reactor body 1, allowing the reactor to be stably placed in the designated position. The temperature sensor 7 monitors the temperature inside the reactor body 1 in real time and displays the temperature data on the display 8. Material is added to the inner cavity of the reactor body 1 through the feeding hopper. After the material reaction is completed, the valve on the discharge port is opened for rapid discharge. The exhaust volume of the exhaust pipe is controlled by the solenoid valve to create an air circulation environment in the cavity.

[0033] The working principle of this utility model is as follows: Material is fed into the inner cavity of the vessel 1, and the stirring motor 501 is turned on. The output end of the stirring motor 501 drives the stirring rod 502 to rotate, which in turn drives the stirring frame 503 on its surface to rotate. The stirring frame 503 drives the scraper 504 to rotate, simultaneously stirring the material and scraping and cleaning the inner wall of the vessel 1. At the same time, the temperature sensor 7 monitors the temperature of the inner cavity of the vessel 1 in real time. When the temperature exceeds the set value, the cooling plates 306 are turned on. The two cooling plates 306 are energized and operate, lowering the temperature of the inner cavity of the air-cooled box 301 and the surface of the coil 305. The fan 303 then operates to draw in external air. The gas flows into the inner cavity of the coil 305 and is cooled as it flows through the curved inner cavity of the coil 305. The cooled gas enters the cavity, which lowers the temperature of the inner cavity of the vessel body 1. When the temperature is lower than the set value, the electric heating plate 307 is turned on. The two electric heating plates 307 are powered on and run, which raises the temperature of the inner cavity of the hot air box 304 and the surface of the coil 305. The air valve leading to the inner cavity of the air-cooled box 301 is closed, and the fan 303 runs to draw outside air into the inner cavity of the hot air box 304. The gas is heated as it flows through the inner cavity of the coil 305. The hot air enters the cavity, which raises the temperature of the inner cavity of the vessel body 1, thereby controlling the temperature of the inner cavity of the vessel body 1 to be maintained within the set value range.
