Description

Technical Field

[0001] This invention relates to the field of anti-clogging devices, specifically an anti-clogging device for a casting machine. Background Technology

[0002] The existing casting machine casting system generally consists of a material tank and a vacuum pump. During casting, the vacuum pump first evacuates the material pipe (the purpose is to remove air bubbles contained in the material. After the air bubbles are released, the material is poured into the mold frame or mold to form the mold or part). In this way, the water vapor, material particles and air in the material tank will be discharged into the vacuum pump along the pipe.

[0003] When the material in the feed tube is hydrocarbon polycaprolactam, hydrocarbon polycaprolactam is a linear polyamide (see linear polymers) produced by ring-opening polymerization of caprolactam monomers. It has an NH(CH2)5CO repeating unit structure, excellent tensile strength and wear resistance, and elasticity. It is mainly used to manufacture synthetic fibers and can also be used as an engineering plastic. The material properties of this type of hydrocarbon polycaprolactam are that it will slowly solidify and crystallize at temperatures below 70℃. During the casting process, this type of material is prone to solidification and crystallization, adhering to the wall of the vacuum pipe. Over time, it will block the vacuum pipe, affect the efficiency of the vacuum pump, and lead to equipment damage and production stoppage.

[0004] The existing solutions to the above problems involve periodically disassembling the pipeline, cleaning the vacuum pump, and heating the pipeline to turn the crystalline particles adhering to the pipeline into liquid and discharge them. The crystals adhering to the vacuum pump also need to be physically removed. This method is laborious, environmentally unfriendly, and the materials cannot be recycled, resulting in waste. Therefore, it is necessary to design an anti-clogging device for polymer casting machines with melting points between 70°C and 200°C. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-clogging device for a casting machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a casting machine anti-clogging device, including a vacuum pump;

[0007] The first suction pipe is fixedly connected to the top of the vacuum pump;

[0008] A vacuum container, which is fixedly connected to the other end of the first suction pipe;

[0009] The second suction pipe is fixedly connected to the inside of the vacuum tank;

[0010] A buffer tank, which is fixedly connected to the other end of the second suction pipe;

[0011] The first switching valve is located at the connection between the second extraction pipe and the buffer tank.

[0012] The present invention further illustrates that the buffer tank is provided with a plurality of scrapers inside, the scrapers are connected by a connecting rod, and a rotary motor is connected to the top of the connecting rod;

[0013] The present invention further illustrates that the top of the buffer tank is fixedly connected to an air suction pipe, one end of the air suction pipe connected to the buffer tank is fixedly installed with a power pump, and the other end of the air suction pipe is fixedly connected to an isolation tank, the interior of which is provided with several smoke filter layers;

[0014] The present invention further illustrates that a support frame is provided on the right side of the vacuum pump, and a fixing frame is fixedly installed on the top of the support frame. The top of the fixing frame is inclined at an angle of 45°, and fixing ropes are fixedly connected to both sides of the top of the fixing frame.

[0015] The present invention further illustrates that a third pipe is fixedly connected to the top of the inner wall of the isolation tank, a second pipe is connected to the top of the third pipe, the second pipe is wrapped with an insulation layer, and the second pipe has a capillary structure inside.

[0016] The present invention further illustrates that the other end of the second pipe is connected to the first pipe, and the other end of the first pipe is fixedly connected to a material tank;

[0017] The present invention further explains that the anti-clogging device consists of a condensation exchange system, a buffer tank, and an isolation tank, forming a three-stage anti-clogging system. One end of the condensation exchange system is connected to the material tank, and the other end is connected to the isolation tank. The isolation tank is then connected to the vacuum tank through a suction pipe. The vacuum tank is connected to the vacuum pump through a first suction pipe, forming a detailed anti-clogging process.

[0018] The present invention further explains that the first step of the above-mentioned anti-clogging process specifically includes:

[0019] The first anti-clogging method is a gravity-flow recovery method. The condensation exchange system consists of a first pipe, a second pipe, and a third pipe forming an inverted U-shape. The second pipe is placed at an angle, tilted 45° to the upper left of the first pipe, and fixed to the frame by a fixing rope. The internal structure of the second pipe is a capillary structure composed of multiple thin tubes, and the second pipe is wrapped with an insulation layer to maintain the temperature of the second pipe, making it difficult for the polymer material to crystallize. When the vacuum pump is started, a vacuum is drawn. When the water vapor inside the polymer material in the tank passes through the second pipe, it flows back into the tank through the first pipe due to the angle.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention:

[0021] (1) By setting up a condensation exchange system, the inverted U-shaped design of the condensation exchange system can make the material

[0022] The water vapor in the tank flows back into the tank under the action of the inclined angle, which plays a role in recovering water vapor;

[0023] (2) By providing an insulation layer on the outside of the second pipe, the temperature of the second pipe can be maintained, making it difficult for the polymer material to crystallize and preventing crystallization inside the pipe from causing blockage. Attached Figure Description

[0033] The buffer tank 6 is equipped with several scrapers 17 inside. The scrapers 17 are used to scrape off the crystals adhering to the tank wall of the buffer tank 6. The scrapers 17 are connected by a connecting rod. A rotary motor is connected to the top of the connecting rod. The rotary motor is connected to a power source. When the power source starts the rotary motor, the rotary motor drives the connecting rod and the scrapers 17 to rotate together to clean the tank wall of the buffer tank 6.

The power pump 701 is externally connected to a power source. When the power source starts, the power pump 701 provides power to the suction pipe 7. An isolation tank 8 is fixedly connected to the other end of the suction pipe 7. The isolation tank 8 is provided with several smoke filter layers 18. The smoke filter layers 18 contain activated carbon and are used to adsorb toxic gases.

[0035] A support frame 14 is provided on the right side of the vacuum pump 1. The buffer tank 6 and the isolation tank 8 are fixedly installed on the top of the support frame 14. A fixing frame 15 is also fixedly installed on the top of the support frame 14. The top of the fixing frame 15 is tilted at an angle of 45°.

The three-way regulating valve 13 is used to transport the medium inside the material tank 12 to the first pipe 11.

[0038] Working principle:

[0039] The anti-clogging device consists of a condensation exchange system, a buffer tank 6, and an isolation tank 8, forming a three-stage anti-clogging system. One end of the condensation exchange system is connected to the material tank 12, and the other end is connected to the isolation tank 8. The vacuum tank 3 is then connected to the suction pipe 7 on the isolation tank 8. The vacuum tank 3 is connected to the vacuum pump 1 through the first suction pipe 2, forming a detailed anti-clogging process.

[0040] The first anti-clogging method is a gravity-flow recovery method. The condensation exchange system is designed in an inverted U-shape by the first pipe 11, the second pipe 10 and the third pipe 9. The second pipe 10 is placed at an inclined angle, set at 45° to the upper left of the first pipe 11, and is fixed to the fixing frame 15 by the fixing rope 16. The internal structure of the second pipe 10 is a capillary structure 102 composed of multiple thin tubes, and the second pipe 10 is wrapped with a heat insulation layer 101. The heat insulation layer 101 is used to maintain the temperature of the second pipe 10, so that the polymer material is not easy to crystallize. The vacuum pump 1 is started to start vacuuming. When the water vapor inside the polymer material in the material tank 12 passes through the second pipe 10, it flows back into the material tank 12 under the action of the inclined angle.

[0041] The second anti-clogging method uses an isolation tank 8, with a third pipe 9 extending into the bottom of the isolation tank 8. Multiple isolation tanks 8 can be configured. Water vapor, material particles, and air in the second pipe 10 are partially returned to the material tank 12, while the remaining portion enters the isolation tank 8. The isolation tank 8 is equipped with a smoke filter layer 18, which filters out toxic gases from the water vapor, material particles, and air, ensuring that the water vapor and material particles do not affect the vacuum pump 1, thus ensuring the safety of the vacuum pump 1.

[0042] The third anti-clogging measure uses a buffer tank 6, which is equipped with a scraper 17. When the polymer material enters the buffer tank 6, crystallization occurs inside the buffer tank 6 due to the temperature being below 70°C. At this time, the rotary motor is started, and the rotary motor drives the scraper 17 to scrape off the crystals inside the buffer tank 6. The bottom of the buffer tank 6 is opened to clean and remove the crystals adhering to the tank.
