Abstract
Description
Technical Field
[0001] This utility model relates to a vacuum isolation container, specifically a vacuum isolation container. Background Technology
[0002] In the production process of modified plastics, the related production materials usually contain high-value raw materials such as various chemical additives and pigments. Therefore, using vacuum isolation tanks during processing can effectively avoid dust leakage and material contamination, ensuring a clean production environment and worker safety.
[0003] Currently, vacuum isolation tanks have a complex structure and unreasonable design, typically placed horizontally. When conveying modified plastic production materials, impurities such as moisture, air, and other volatile components are transported out with the airflow. Vacuum isolation tanks lack a structure for automatically separating and discharging these impurities. The presence of these impurities increases air bubbles and defects in the finished product. Furthermore, existing vacuum isolation tanks cannot balance extrusion pressure fluctuations, resulting in poor practicality. Therefore, the inventors have improved the structure of the vacuum isolation tank. Utility Model Content
[0004] The purpose of this utility model is to provide a vacuum isolation tank, which has the advantages of simple structure, reasonable design, automatic separation of materials and impurities, effective removal of moisture, air and other volatile components from materials, reduction of bubbles and defects in products, purification treatment of materials, improvement of material purity, and buffer container to balance extrusion pressure fluctuations, allowing continuous production without interruption. It solves the problems mentioned in the above technical background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum isolation tank, which includes a main tank body and a cleaning mechanism disposed on the main tank body. The main tank body includes a cylindrical material conveying tank, which has an internally hollow cavity structure. An air inlet external thread connector is connected to the top of one side of the material conveying tank, and an exhaust external thread connector is connected to the top of the outer circle of the material conveying tank. The exhaust external thread connector is located at the end of the material conveying tank away from the air inlet external thread connector. A partition is fixed to the top of the cavity of the material conveying tank. The cleaning mechanism includes a front quick clamp, a rear quick clamp, and a bottom quick clamp. The front quick clamp and the rear quick clamp are both fixed to the top of the material conveying tank and are distributed at both ends of the partition. Therefore, the front quick clamp and the rear quick clamp are used to clean the space on both sides of the partition. The bottom quick clamp is fixed to the end of the material conveying tank away from the exhaust external thread connector, and a drain pipe is disposed below the bottom quick clamp.
[0006] Preferably, a material flow port is formed below the partition in the material conveying tank cavity. The partition divides the space inside the material conveying tank cavity into two parts. After the airflow carrying the modified plastic production material enters the material conveying tank cavity through the air inlet external thread joint, it will first collide with the partition. The material and the impurities contained therein will fall after touching the partition. After that, the impurities will slide down and be discharged into the drain pipe, while the production material will move through the material flow port toward the exhaust external thread joint.
[0007] Preferably, a guide slope is formed below the material flow port in the material conveying tank cavity. The guide slope is inclined and the angle of inclination of the guide slope is between 2° and 8°. Through the inclined guide slope, impurities in the material slide down the guide slope naturally under the action of gravity and eventually enter the drain pipe.
[0008] Preferably, an external pipe is fixedly connected to the top of the material conveying tank, and the length direction of the material conveying tank is perpendicular to the length direction of the external pipe. The external pipe is used to install a negative pressure vacuum gauge.
[0009] Preferably, the partition is inclined, and the angle of inclination of the partition is between 80° and 87°.
[0010] Preferably, three cleaning pipes are fixed on the material conveying tank. The front quick clamp, the rear quick clamp, and the bottom quick clamp are respectively installed on the three cleaning pipes. Two of the cleaning pipes are distributed on both sides of the partition, and the other cleaning pipe is located on the side of the material conveying tank.
[0011] Preferably, it also includes a support frame, which is fixed to the bottom of the material conveying tank, and the bottom of the support frame is provided with four rollers. The support frame can move as the rollers roll, so that the main tank can be moved easily.
[0012] Preferably, the drain pipe is inclined and installed at the end of the material conveying tank near the exhaust external thread joint. The drain pipe is used to receive impurities that slide down from the guide slope and discharge the impurities to the outside. A valve is installed on the drain pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model provides a vacuum isolation tank, which includes a main tank body and a cleaning mechanism disposed on the main tank body. The overall structure is simple and reasonably designed. The main tank body includes a columnar material conveying tank, which is a hollow cavity structure. A baffle is fixed at the top of the material conveying tank cavity. The baffle is inclined. The airflow carrying the modified plastic production material enters the material conveying tank cavity from the external threaded inlet joint and will first collide with the baffle. The material and the impurities contained therein will fall after touching the baffle. The impurities include moisture, air and other volatile components. These impurities will slide down and be discharged into the drain pipe. Therefore, the automatic separation of material and impurities is effectively realized, the moisture, air and other volatile components in the material are effectively removed, the bubbles and defects in the product are reduced, the material is purified, and the purity of the material is improved. It is highly practical.
[0015] 2. This utility model features a guide ramp at the bottom of the material conveying tank cavity, with an inclination angle between 2° and 8°. By expanding the capacity of the material conveying tank, the airflow velocity is rapidly reduced, allowing the vacuum isolation tank to act as a buffer container to balance extrusion pressure fluctuations, enabling continuous production without interruption. At the same time, it prevents material from flowing back into the vacuum main pipeline. The optimized design of the material conveying tank can directly increase its service life by 2 to 3 times. The guide ramp allows impurities in the material to slide down naturally under gravity and eventually enter the drain pipe, where they are automatically discharged, eliminating the hassle of manual cleaning.

[0024] Please see Figure 1 One embodiment of this utility model is a vacuum isolation tank, which includes a main tank body 1 and a cleaning mechanism 3 disposed on the main tank body 1.
[0025] Please see Figure 2The main tank 1 includes a cylindrical material conveying tank 11, which has a hollow internal cavity structure. An air inlet connector 12 is connected to the top of one side of the material conveying tank 11. The air inlet connector 12 is used to connect to the vacuum port of the extruder, allowing airflow to enter the cavity of the material conveying tank 11 through the air inlet connector 12. An exhaust connector 13 is connected to the outer circumference of the material conveying tank 11. The exhaust connector 13 is used to connect to a water ring vacuum pump for discharging airflow. The exhaust connector 13 is located at the end of the material conveying tank 11 furthest from the air inlet connector 12. An external pipe 15 is fixedly connected to the top of the material conveying tank 11. The length direction of the material conveying tank 11 is perpendicular to the length direction of the external pipe 15. The external pipe 15 is used to install a negative pressure vacuum gauge, which measures pressure below atmospheric pressure, i.e., vacuum level. The structure of the negative pressure vacuum gauge is existing technology and will not be described in detail here. Three cleaning devices are fixed on the material conveying tank 11. The cleaning mechanism 3 includes a front quick clamp 31, a rear quick clamp 32, and a bottom quick clamp 33. The front quick clamp 31 and the rear quick clamp 32 are both fixed to the top of the material conveying tank 11, and are located at both ends of the partition 14. Therefore, the front quick clamp 31 and the rear quick clamp 32 are used to clean the partition 14. 4. The space on both sides is cleaned. The bottom quick clamp 33 is fixed to the end of the material conveying tank 11 away from the exhaust external thread connector 13. A drain pipe 34 is provided below the bottom quick clamp 33. The front quick clamp 31, the rear quick clamp 32 and the bottom quick clamp 33 are respectively installed on the three cleaning pipes 16. A bracket 2 is fixed at the bottom of the material conveying tank 11. Four rollers are provided at the bottom of the bracket 2. The bracket 2 can move with the rolling of the rollers, so that the main tank 1 can be moved easily.
[0026] Please see Figure 3A baffle 14 is fixed to the top of the material conveying tank 11 cavity. The baffle 14 is inclined at an angle between 80° and 87°. The baffle 14 is used to intercept the material and its impurities. A material flow port 111 is formed below the baffle 14 in the material conveying tank 11 cavity. The baffle 14 divides the space in the material conveying tank 11 cavity into two parts. After the airflow carrying the modified plastic production material enters the material conveying tank 11 cavity through the inlet external thread connector 12, it will first collide with the baffle 14. The material and its impurities will fall after touching the baffle 14. Then, the impurities will naturally slide down to the drain pipe 34, while the production material will separate from the impurities. The production material moves with the airflow and moves through the material flow port 111 to the exhaust external thread connector 13. Therefore, the automatic separation of material and impurities is achieved, and the material is purified. The material conveying tank 11 has improved purity. Furthermore, a guide slope 112 is formed below the material flow port 111 within the material conveying tank 11 cavity. The guide slope 112 is inclined, with an angle between 2° and 8°. Through the inclined guide slope 112, impurities separated from the material naturally slide down the guide slope 112 under gravity. The expansion of the material conveying tank 11 causes a sudden drop in airflow velocity, preventing backflow into the vacuum main pipeline. The impurities contain moisture, air, and other volatile components. The optimized design of the material conveying tank 11 can directly increase its service life by 2 to 3 times. Finally, the impurities are automatically discharged into the drain pipe 34, eliminating the need for manual cleaning. The vacuum main pipeline is located at the end of the inlet external thread connector 12 furthest from the material conveying tank 11, and its structure is existing technology.
[0027] Please see Figure 4 The drain pipe 34 is inclined and installed at one end of the material conveying tank 11 near the exhaust external thread joint 13. The drain pipe 34 is used to receive impurities that slide down from the guide slope 112 and discharge the impurities to the outside. A valve is installed on the drain pipe 34. In this embodiment, the valve is an electric valve.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
