Description

Technical Field

[0001] This utility model relates to the field of vacuum devolatilization, specifically to a vacuum devolatilization device for acidic solids. Background Technology

[0002] A vacuum devolatilization device for acidic solids is a chemical equipment specifically designed for removing volatile components from acidic solid materials. The following sections discuss its principle, structure, advantages, and application scenarios. The device uses a vacuum system to create a vacuum inside the unit, reducing the partial pressure of volatile components on the material surface. According to the law of partial pressure, volatile components escape more easily from solid materials under vacuum, thus accelerating the devolatilization process.

[0003] Existing devolatilization devices have many limitations when processing acidic solid materials. Most devices only use simple unidirectional stirring or have inadequate stirring structures, making it difficult to comprehensively and fully agitate the acidic solid materials in different locations within the vacuum devolatilization chamber. This results in uneven heating and gas contact during the devolatilization process, with some areas achieving better removal of volatile components. Therefore, a vacuum devolatilization device for acidic solids is needed to help solve this problem. Utility Model Content

[0004] Therefore, the purpose of this invention is to provide a vacuum devolatilization device for acidic solids, addressing the limitations of existing devolatilization devices in processing acidic solid materials. Most devices employ only a simple unidirectional stirring method, or the stirring structure is insufficient, making it difficult to comprehensively and fully agitate the acidic solid material at different locations within the vacuum devolatilization chamber. This results in uneven heating and gas contact during the devolatilization process, hindering the effective removal of volatile components from certain areas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an acidic solid vacuum devolatilization device, comprising a vacuum devolatilization cylinder, an internal cavity for receiving the vacuum devolatilization cylinder, a top seat installed at the top of the vacuum devolatilization cylinder, a feed inlet at the top of the top seat, a feed pipe installed at the feed inlet, an exhaust pipe and a conduit installed at the top of the vacuum devolatilization cylinder, a devolatilization pipe installed on the exhaust pipe, the devolatilization pipe communicating with a collection tank, a ball valve installed on the devolatilization pipe, and a vacuum pump installed at the end of the conduit away from the vacuum devolatilization cylinder;

[0006] An installation tube is installed at the center of the top of the vacuum devolatilization cylinder. A rotating rod is rotatably installed inside the installation tube. A power component to assist the rotation of the rotating rod is installed at the top of the installation tube. The bottom of the rotating rod extends into the receiving cavity of the vacuum devolatilization cylinder. A cross-shaped fixing frame is fixed in the middle section of the receiving cavity of the vacuum devolatilization cylinder. An agitation component to assist the stirring of materials is installed at the fixing frame. The rotating rod is connected to the agitation component.

[0007] The present invention is further configured such that the agitation assembly includes a first agitation rod rotatably disposed at the top of the fixed frame and a second agitation rod disposed at the bottom of the fixed frame, and a transmission cavity is provided at the center of the fixed frame, wherein a transmission assembly for driving the first agitation rod and the second agitation rod to rotate is installed in the transmission cavity.

[0008] The present invention is further configured such that the transmission assembly includes a meshing gear and a meshing toothed disc rotatably disposed in the transmission cavity, a transmission gear is symmetrically rotatably disposed in the transmission cavity, the inner edge of the meshing toothed disc meshes with the outer edge of the transmission gear, and the outer edge of the meshing gear meshes with the outer edge of the transmission gear.

[0009] The present invention is further configured such that the bottom of the first stirring rod is fixed at the top of the transmission assembly, the top of the second stirring rod is fixed at the bottom of the meshing gear plate, and a fixing rod is fixed on both the first stirring rod and the second stirring rod.

[0010] The present invention is further configured such that the power assembly includes a transmission gearbox mounted on the mounting pipe, the output end of the transmission gearbox is connected to the top of the rotating rod, the rotating rod is fixed to the top of the first agitating rod, and a servo motor is mounted on the input end of the transmission gearbox.

[0011] The present invention is further configured such that a pressure gauge and a temperature gauge are installed at the top of the top seat, and a discharge pipe is installed at the bottom of the vacuum devouring cylinder.

[0012] The present invention is further provided that a fixed base is fixed at the outer edge of the vacuum devouring cylinder, and a support leg is vertically fixed at the bottom of the fixed base.

[0013] In summary, the present invention has the following advantages: the present invention, through the agitation component, enables the first agitator and the second agitator to rotate simultaneously, thereby comprehensively agitating the acidic solid material at different positions in the vacuum devolatilization cylinder, ensuring that the material is heated evenly during the devolatilization process. If a heating device is provided, the problem of insufficient local devolatilization is avoided, thus improving the devolatilization quality.

[0014] Through the transmission components, the first and second stirring rods rotate in opposite directions during operation. This unique stirring method creates a more complex and intense material flow within the vacuum devolatilization chamber. Under the shear force and convection generated by the opposite rotation, the acidic solid material can be mixed more thoroughly, and the material in different locations exchanges with each other, making the distribution of volatile components within the material more uniform. This avoids the accumulation of volatile components or insufficient volatilization in localized areas, thereby improving the overall devolatilization efficiency. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] An acidic solid vacuum devouring device, such as Figure 1-4As shown, the device includes a vacuum devolatilization chamber 1, an electric heating tube installed inside the vacuum devolatilization chamber 1, a fixed base 2 fixed at the outer edge of the vacuum devolatilization chamber 1, a support leg 3 vertically fixed at the bottom of the fixed base 2, a receiving cavity opened inside the vacuum devolatilization chamber 1, a top seat 4 installed at the top of the vacuum devolatilization chamber 1, a pressure gauge 6 and a temperature gauge 7 installed at the top of the top seat 4, a discharge pipe installed at the bottom of the vacuum devolatilization chamber 1, a feed inlet opened at the top of the top seat 4, a feed pipe 5 installed at the feed inlet, an exhaust pipe 20 and a conduit 21 installed at the top of the vacuum devolatilization chamber 1, a devolatilization pipe 19 installed on the exhaust pipe 20, the devolatilization pipe 19 is connected to a collection tank, a ball valve is installed on the devolatilization pipe 19, and a vacuum pump 211 is installed at the end of the conduit 21 away from the vacuum devolatilization chamber 1. The vacuum pump 211 establishes a vacuum environment, reduces the partial pressure of volatile components on the surface of acidic solid materials, and makes it easier for volatile components to escape.

[0022] The pressure gauge 6 and temperature gauge 7 installed on the top of the top seat 4 can monitor the pressure and temperature inside the vacuum devolatilization cylinder 1 in real time. Operators can adjust the devolatilization parameters, such as the pumping speed of the vacuum pump 211 and the rotation speed of the servo motor 10, in a timely manner according to changes in pressure and temperature, to ensure that the devolatilization process is carried out under suitable conditions, which is conducive to improving the devolatilization effect and ensuring the safe operation of the equipment.

[0023] An installation tube is installed at the center of the top of the vacuum devolatilization cylinder 1. A rotating rod 11 is rotatably installed inside the installation tube. A power assembly 8 for assisting the rotation of the rotating rod 11 is installed at the top of the installation tube. The power assembly 8 includes a transmission gear box 9 installed on the installation tube. The output end of the transmission gear box 9 is connected to the top of the rotating rod 11. The rotating rod 11 is fixed to the top of the first stirring rod 13. A servo motor 10 is installed at the input end of the transmission gear box 9. The bottom of the rotating rod 11 extends into the receiving cavity of the vacuum devolatilization cylinder 1. A cross-shaped fixing frame 121 is fixed in the middle section of the receiving cavity of the vacuum devolatilization cylinder 1. An agitation assembly 12 for assisting the agitation of materials is installed at the fixing frame 121. The agitation assembly 12 includes a first stirring rod 13 rotatably installed at the top of the fixing frame 121 and a second stirring rod 14 at the bottom.

[0024] By using the agitation component 12 and the transmission component 15 to make the first agitator 13 and the second agitator 14 rotate simultaneously, the acidic solid material in different positions in the vacuum devolatilization cylinder 1 is thoroughly agitated, ensuring that the material is heated evenly during the devolatilization process. If there is a heating device, the problem of insufficient local devolatilization is avoided, and the devolatilization quality is improved.

[0025] A transmission cavity is provided at the center of the fixed frame 121. A transmission assembly 15 is installed in the transmission cavity to drive the first stirring rod 13 and the second stirring rod 14 to rotate. The transmission assembly 15 includes a meshing gear 16 and a meshing gear disk 17 rotatably disposed in the transmission cavity. A transmission gear 18 is symmetrically rotatably disposed in the transmission cavity. The inner edge of the meshing gear disk 17 meshes with the outer edge of the transmission gear 18, and the outer edge of the meshing gear 16 meshes with the outer edge of the transmission gear 18. The rotating rod 11 is connected to the stirring assembly 12.

[0026] With the transmission assembly 15 in place, the first stirring rod 13 and the second stirring rod 14 rotate in opposite directions during operation. This unique stirring method creates a more complex and intense material flow within the vacuum devolatilization cylinder 1. Under the shear force and convection generated by the opposite rotation, the acidic solid material can be mixed more thoroughly, and the material at different locations exchanges with each other, making the distribution of volatile components within the material more uniform. This avoids the accumulation of volatile components or insufficient volatilization in local materials, thereby improving the overall devolatilization efficiency.

[0027] The working principle of this utility model:

[0028] Start the vacuum pump 211 installed at the end of the conduit 21 away from the vacuum devouring cylinder 1. The vacuum pump 211 starts working and extracts the air from the vacuum devouring cylinder 1, so that a vacuum environment is gradually formed inside the vacuum devouring cylinder 1.

[0029] As the vacuum level increases, the partial pressure of volatile components on the surface of acidic solid materials decreases. According to the principle of volatile substance diffusion, the decrease in partial pressure will make it easier for volatile components to escape from the solid material.

[0030] The servo motor 10 in the power assembly 8 is activated, driving the transmission gearbox 9 to rotate. The output end of the transmission gearbox 9 causes the rotating rod 11 to rotate. Since the rotating rod 11 is fixed to the top of the first stirring rod 13, the first stirring rod 13 will rotate accordingly. At the same time, the rotation of the rotating rod 11 drives the meshing gear 16 in the transmission assembly 15 to rotate. The meshing gear 16 meshes with the outer edge of the transmission gear 18, thereby driving the transmission gear 18 to rotate. The transmission gear 18 then meshes with the inner edge of the meshing gear disk 17, causing the meshing gear disk 17 to rotate. The top of the second stirring rod 14 is fixed at the bottom of the meshing gear disk 17, so the second stirring rod 14 will also rotate. The fixed rods on the first stirring rod 13 and the second stirring rod 14 will fully agitate the acidic solid material in the vacuum devolatilization cylinder 1, causing the material to continuously tumble inside the cylinder, increasing the contact area between the material and the gas. At the same time, the raw materials inside the vacuum devolatilization cylinder 1 are heated, accelerating the diffusion and volatilization rate of volatile components.

[0031] Volatile components volatilized from acidic solid materials enter a collection tank connected to them through exhaust pipe 20 and devolatilization pipe 19. The ball valve on devolatilization pipe 19 can control the flow of volatile components. When a certain amount is collected or the collection requirements are met, the ball valve can be closed.

[0032] After the devolatilization process is completed, open the discharge pipe at the bottom of the vacuum devolatilization cylinder 1 to discharge the acidic solid material that has undergone devolatilization treatment from the cylinder.

[0033] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
