Description

Technical Field

[0001] The invention relates to the technical field of chemical mixing, in particular to a mixing and placing device for polytetrafluoroethylene dispersion material. Background Art

[0002] Polytetrafluoroethylene, commonly known as the "king of plastics", is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It is white waxy, translucent, heat-resistant and cold-resistant. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low, so it can be used as a lubricant. Among them, polytetrafluoroethylene emulsion is a commonly used raw material. Polytetrafluoroethylene emulsion is a dispersed concentrate after tetrafluoroethylene polymerization in the presence of a non-ionic surfactant, and the solid content of polytetrafluoroethylene is about 60% (wt). Products treated with dispersed concentrated liquid have the ability to resist chemical corrosion, such as strong acid, strong alkali, strong oxidant, etc., have outstanding heat resistance, cold resistance and wear resistance, and excellent electrical insulation, and are not affected by temperature and frequency. They can be directly used to impregnate porous materials such as asbestos products, glass fibers, ceramics and electric carbon products, etc., and can be used to make anti-sticking and anti-corrosion coatings; they can also be used to coat glass cloth and make laminated products; they can also be directly spun to make special synthetic fibers, which are widely used in defense industry, rubber industry, electronic battery industry and other departments; The polymerization of polytetrafluoroethylene dispersion requires stirring, and corresponding additives can be added to the polytetrafluoroethylene emulsion according to different usage occasions to make it fully mixed, which can change the physical properties of the polytetrafluoroethylene product.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The invention provides a mixing and placing device for polytetrafluoroethylene dispersion material.

[0022] First embodiment: Please combine Figures 1 to 9 , a mixing material placement device for polytetrafluoroethylene dispersion material, comprising a base 1 and four storage mechanisms 3; A mixing tank 2 is mounted on the top of the base 1, a mounting frame 11 is fixedly mounted on the outer wall of the mixing tank 2, and a feed pipe 14 is fixedly mounted on the upper surface of the tank cover 32; A rotating motor 15 is installed on the inner top of the mounting frame 11 by bolts, and a turntable 16 is connected to the keyway of the output shaft of the rotating motor 15. Each of the storage mechanisms 3 includes a storage tank 31 installed on the outer wall of the turntable 16, and a tank cover 32 is installed on the top of the storage tank 31 by bolts, and a one-way valve pipe 318 is installed on the top of the tank cover 32. A floating seal 33 is installed at the axis of the bottom end of the storage tank 31, and the interior of the floating seal 33 is slidably connected to a lifting pipe 34 along the vertical direction of the storage tank 31. A first plug 35 is fixedly provided on the inner wall of the lifting pipe 34, and a connecting rod 36 is fixedly provided at the axis of the top end of the first plug 35. A limiting rod is fixedly provided on the inner wall of the storage tank 31 37, a second plug 316 is fixedly provided at the top of the connecting rod 36, a top pipe 314 is fixedly provided at the top axis of the tank cover 32, a limit frame 38 is fixedly provided at the bottom of the storage tank 31 and on both sides of the lifting tube 34, a return spring 39 is fixedly provided inside the limit frame 38, a connecting plate 310 is fixedly provided on both sides of the lifting tube 34, a folding compression bag 311 is fixedly provided on the lower surface of the storage tank 31 and on one side of the limit frame 38, a first air pipe 312 and a second air pipe 313 are respectively sealedly installed on the outer wall of the folding compression bag 311, a first sealing ring 315 is embedded in the upper surface of the top pipe 314, and a second sealing ring 317 is embedded in the lower surface of the lifting tube 34; See also Figure 4 and Figure 5 There are four storage mechanisms 3 in total, and the structures of the four storage mechanisms 3 are exactly the same. The outer walls of the four storage tanks 31 are mounted on the rotating disk 16 by bolts.

[0023] See also Fig. 9In actual use, the user can add different solvents, additives, dispersion powders and other media related to the polytetrafluoroethylene dispersion mixing process into the four storage tanks 31. The user can insert the corresponding external medium pipe into the one-way valve pipe 318, so that various media can enter the corresponding storage tanks 31.

[0024] See also Figure 4 , Figure 6 and Figure 7 : When the materials are not mixed, the lifting pipe 34 and the feeding pipe 14 are separated. In this state, the first plug 35 is used to block the connecting port between the lifting pipe 34 and the storage tank 31, and the second plug 316 is used to block the pipe opening of the top pipe 314. In this state, the medium in each storage tank 31 can be stably stored in the storage tank 31.

[0025] See also Figure 4 and Fig. 9 : When the user needs to add various media to the mixing tank 2 for mixing, the rotating motor 15 can be started to drive the turntable 16 to rotate clockwise around the top axis of the mounting frame 11. When the bottom inclined surface of the lifting tube 34 rotates to the feed tube 14 in a fixed state, the two inclined surfaces will affect each other to slide and rise, so that the lifting tube 34 can rise smoothly and overlap with the feed tube 14. When the lifting tube 34 rises, it will drive the connecting plates 310 on both sides to slide inside the limit frame 38, compressing the reset spring 39. The rising lifting tube 34 will affect the synchronous control of the first plug 35, the connecting rod 36, and the second plug 316 to rise together; This realizes the conduction from the top pipe 314 to the storage tank 31, and from the storage tank 31 to the lifting pipe 34 to the feeding pipe 14.

[0026] See also Figure 3 and 9 : After conduction, the user can start the air intake pump 10, and the air intake pump 10 can be connected to an external nitrogen device. The air intake pump 10 can add nitrogen to the storage tank 31, and the pressure in the storage tank 31 increases accordingly. The medium in the storage tank 31 is transported to the mixing tank 2 through the internal and external pressure difference.

[0027] See also Fig. 9 : When the connecting plates 310 are rising, one of the connecting plates 310 will rise and squeeze the folding compression bag 311. At this time, the folding compression bag 311 compresses the internal gas and transports it to the first sealing ring 315 and the second sealing ring 317 through the first air pipe 312 and the second air pipe 313 respectively. This realizes the expansion and sealing of the connection position between the lifting pipe 34 and the feeding pipe 14 by the second sealing ring 317, and the expansion and sealing of the connection position between the top pipe 314 and the bottom end of the intake pump 10.

[0028] An inspection port 12 is provided on the outer wall of the mixing tank 2 and away from the mounting frame 11. An inspection door 13 is rotatably connected to the outer wall of the inspection port 12. A mounting plate 9 is fixedly provided on the upper surface of the mixing tank 2, and an air intake pump 10 is installed on the upper surface of the mounting plate 9.

[0029] See also Figures 1 to 3 : In actual use, the user can install an external vacuum conveyor outside the inspection port 12, which can be used to quickly convey the medium after mixing in the mixing tank 2. At the same time, the inspection port 12 can also be used for inspection and cleaning of the mixing tank 2. During the mixing work, the inspection port 12 needs to be closed by flipping the inspection door 13.

[0030] The lower surface of the turntable 16 is rotatably connected to the upper surface of the mounting frame 11 via a bearing, and the lower surface of the lifting tube 34 and the lower surface of the feeding tube 14 are inclined surfaces with the same slope.

[0031] The connecting plate 310 is slidably connected to the limiting frame 38 , and the bottom of the return spring 39 is fixedly connected to the upper surface of the connecting plate 310 .

[0032] It is understandable that the limiting rod 37 is used to limit the connecting rod 36 , so that the longer connecting rod 36 can be more stable during the lifting movement, and the influence of the shaking of the connecting rod 36 on the second plug 316 can be effectively avoided.

[0033] The first plug 35 and the second plug 316 are respectively of a conical structure that is wide at the top and narrow at the bottom. The connecting rod 36 is slidably connected to the limiting rod 37. The outlet end of the second air pipe 313 is sealed with the first sealing ring 315, and the outlet end of the first air pipe 312 is sealed with the second sealing ring 317.

[0034] Preferably, the first plug 35 and the second plug 316 can be made of high-quality hard rubber material, so as to ensure the overall sealing of the storage tank 31.

[0035] See also Figure 6 If dangerous media or chemically unstable media are stored in the storage tank 31, the media is prone to increased gas pressure or expansion in the storage tank 31. Since the first plug 35 is a conical structure, the greater the outward expansion force in the storage tank 31, the tighter the seal of the first plug 35. Therefore, such a design can ensure that the internal environment of the storage tank 31 is safer, and achieve safer storage and placement of different media.

[0036] This embodiment is equivalent to the traditional design of one pipeline for conveying different media. This case is designed with four identical storage mechanisms 3, and different media can be stored in four storage tanks 31. The media can be additives, solutions, dispersed powders, etc. When each storage tank 31 is rotated to the position of the feed pipe 14, the lifting pipe 34 automatically overlaps with the feed pipe 14 to realize the connection between the first plug 35 and the second plug 316 to the storage tank 31, and the medium in the storage tank 31 is added to the mixing tank 2 by nitrogen pressurization. Therefore, such a design realizes the stable storage and automatic integrated operation of the conduction and addition of the mixed medium, which can effectively ensure the stable transportation of flammable and explosive hazardous media, and can also ensure the chemical stability of different media when placed. At the same time, when the lifting pipe 34 and the feed pipe 14 are in the process of closing, the second sealing ring 317 and the first sealing ring 315 are linked to expand for sealing. Such a design can ensure the sealing of the medium during transportation and effectively improve the overall safety.

[0037] Second embodiment: See also Figure 3 , Figures 10 to 13 A mixing motor 4 is installed at the top of the mixing tank 2 and on one side of the mounting plate 9, and a mixing mechanism 5 is installed inside the mixing tank 2; The mixing mechanism 5 includes a rotating rod 51 connected to the output shaft of the mixing motor 4 by a keyway, a cross bar 52 is installed on the outer wall of the rotating rod 51, and a plurality of mixing plates 53 arranged equidistantly are installed on the bottom of the cross bar 52 by bolts, a first limiting plate 54 and a plurality of second limiting plates 55 are fixedly provided at the bottom of the plurality of mixing plates 53, a scraper 57 and a plurality of dividing plates 56 are rotatably connected to the bottom of the plurality of mixing plates 53 and located on one side of the first limiting plate 54 and the second limiting plate 55.

[0038] See also Figure 3 and Fig.10 : In the process of the first embodiment, this is the state of medium addition. In this state, the user starts the mixing motor 4 to drive the rotating rod 51 to control the cross bar 52 to rotate counterclockwise. When the cross bar 52 rotates counterclockwise, it will control the rotation of multiple mixing plates 53.

[0039] See also Fig.10 and Fig.11 : When the mixing plate 53 rotates counterclockwise, the scraper 57 and the dividing plate 56 will synchronously follow the mixing plate 53 to rotate counterclockwise. Since it is a counterclockwise rotation, and secondly, the medium added in the first embodiment exists in the mixing tank 2 at this time, the scraper 57 and the dividing plate 56 will be subject to resistance from the right side. The scraper 57 and the dividing plate 56 can be limited and blocked by the first limiting plate 54 and the second limiting plate 55.

[0040] See also Fig.12 and Fig.13 : When the first embodiment ends work, the user starts the mixing motor 4 to control the rotating rod 51 to rotate clockwise, and the mixing plate 53 will synchronously rotate clockwise with the rotating rod 51. At this time, it is in the mixing and stirring state. There are a lot of mixed media in the mixing tank 2. The clockwise rotating scraper 57 and the dividing plate 56 will be subject to resistance from the left side, so that the scraper 57 and the dividing plate 56 lose the obstruction of the first limit plate 54 and the second limit plate 55, thereby flipping and switching the posture; Fig.12 The posture in can be equivalent to Fig.10 The posture in has the following benefits: The flipped material distributor plate 56 can increase the contact area of ​​the medium in the mixing tank 2, so that more uniform mixing and stirring can be achieved, ensuring sufficient mixing and polymerization.

[0041] The upper outer wall and the bottom end of the rotating rod 51 are both rotatably connected to the top end and the inner bottom end of the mixing tank 2 .

[0042] This embodiment is equivalent to the traditional mixing and stirring design. This case is implemented by counterclockwise rotation and clockwise rotation. In the process of adding the medium, counterclockwise rotation can ensure that while stirring, the scraper 57 and the distributor plate 56 evenly disperse the added medium at the bottom of the mixing tank 2, thereby avoiding the accumulation of the medium. When the addition of the medium is completed, the clockwise rotation will change the posture of the distributor plate 56, which can increase the contact area between the distributor plate 56 and the internal medium, thereby ensuring more complete mixing.

[0043] Third embodiment: See also Fig.12 and Fig.14 , also includes an exhaust gas treatment mechanism 8, A positioning plate 17 is fixedly disposed on the outer wall of the mounting plate 9, and a one-way rotating assembly 6 and an air intake mechanism 7 are respectively mounted above the positioning plate 17; The one-way rotating assembly 6 includes a ratchet 61 connected to the top of the rotating rod 51 by a keyway, and a ratchet ring 62 is rotatably connected inside the positioning plate 17, and a cam 63 is fixed on the outer wall of the ratchet ring 62; See also Fig.12 : When the rotating rod 51 rotates counterclockwise, it will drive the ratchet 61 to rotate counterclockwise. The counterclockwise rotating ratchet 61 will not affect the control ratchet ring 62, so the cam 63 will not work. When the rotating rod 51 rotates clockwise, it will drive the ratchet 61 to rotate clockwise. The clockwise rotating ratchet 61 will control the ratchet ring 62 to control the cam 63 to rotate clockwise synchronously, thus realizing the unidirectional rotation of the cam 63.

[0044] The air intake mechanism 7 comprises a mounting frame 71 fixed on the upper surface of the positioning plate 17, an air bag 72 is mounted inside the mounting frame 71, a spring pressure plate 73 is slidably connected to the outer wall of the air bag 72 outside the mounting frame 71, and an air intake pipe 74 is sealedly mounted on the outer wall of the air bag 72; The waste gas treatment mechanism 8 includes an exhaust pump 81, the air inlet end of the exhaust pump 81 is sealed with an exhaust pipe 82, the air outlet end of the exhaust pump 81 is sealed with an outlet pipe 83, a stuffing tank 84 is installed above the outlet pipe 83, a discharge pipe 85 is sealed on the top of the stuffing tank 84, and a coil 86 is sealed on the upper end of the exhaust pipe 82, and the coil 86 is located at the inner top of the mixing tank 2.

[0045] See also Fig.14 During the operation of the second embodiment, the mixing tank 2 is in a stirring state. At this time, the polytetrafluoroethylene dispersion in the mixing tank 2 will produce gas during mixing. At this time, the vacuum pump 81 can be started. The vacuum pump 81 draws the gas in the mixing tank 2 into the outlet pipe 83 through the coil 86 and the vacuum pipe 82 and then enters the stuffing tank 84. Since the rotating rod 51 rotates clockwise when the mixing tank 2 is stirred, the cam 63 also rotates clockwise, and the continuous control spring pressure plate 73 repeatedly squeezes the air bag 72. The squeezed gas will enter the stuffing tank 84 through the inlet pipe 74. The gas can increase the flow of the stuffing in the stuffing tank 84 to ensure that the stuffing and the exhaust gas can be fully mixed and processed, and the treated gas is discharged from the discharge pipe 85.

[0046] The outer wall of the ratchet wheel 61 and the inner wall of the ratchet ring 62 are meshed with each other, and the air outlet end of the air inlet pipe 74 and the lower surface of the stuffing tank 84 are sealed and installed.

[0047] This embodiment: During the operation of the second embodiment, the rotating rod 51 will drive the cam 63 to rotate in conjunction with the clockwise rotation. At this time, the amount of polytetrafluoroethylene dispersion inside the mixing tank 2 is very large. Gas will be generated during continuous mixing and stirring. The gas can enter the stuffing tank 84 through the processing of the vacuum pump 81. The rotation of the cam 63 can continuously control the airbag 72 to squeeze the generated gas into the stuffing tank 84, which can accelerate the flow rate of the internal stuffing, thereby ensuring that the gas is fully contacted and mixed with the stuffing, ensuring that the gas can be fully and effectively processed.

[0048] Please refer to Figures 1 to 14 The working principle of the mixing and placing device of polytetrafluoroethylene dispersion provided by the present invention is as follows: Step S1: In actual use, the user can add different solvents, additives, dispersion powders and other media related to the polytetrafluoroethylene dispersion mixing process into the four storage tanks 31. The user can insert the corresponding external medium tube into the one-way valve tube 318, so that various media can enter the corresponding storage tank 31, start the rotating motor 15 to drive the turntable 16 to rotate clockwise around the top axis of the mounting frame 11, and when the bottom inclined surface of the lifting tube 34 rotates to the feed tube 14 in a fixed state, the two inclined surfaces will affect each other to slide up, so that the lifting tube 34 can rise smoothly and overlap with the feed tube 14. When the lifting tube 34 rises, it will drive the connecting plates 310 on both sides to slide inside the limit frame 38, compress the reset spring 39, and the rising lifting tube 34 will affect the synchronous control of the first plug 35, the connecting rod 36 and the second plug 316 to rise together; This realizes the conduction from the top pipe 314 to the storage tank 31, the storage tank 31 to the lifting pipe 34 to the feeding pipe 14, and starts the air intake pump 10. The air intake pump 10 can be connected to an external nitrogen device. The air intake pump 10 can add nitrogen to the storage tank 31, and the pressure in the storage tank 31 increases accordingly. The medium in the storage tank 31 is transported to the mixing tank 2 through the difference between the internal and external pressures.

[0049] Step S2: Start the mixing motor 4 to control the rotating rod 51 to rotate clockwise, and the mixing plate 53 will synchronously follow the rotating rod 51 to rotate clockwise. At this time, it is in the mixing and stirring state. There are a lot of mixed media in the mixing tank 2. The clockwise rotating scraper 57 and the dividing plate 56 will encounter resistance from the left side, so that the scraper 57 and the dividing plate 56 lose the obstruction of the first limit plate 54 and the second limit plate 55, thereby flipping and switching the posture to stir and mix the medium in the mixing tank 2.

[0050] Step S3: The mixing tank 2 is in a stirring state. At this time, the polytetrafluoroethylene dispersion in the mixing tank 2 will produce gas during mixing. At this time, the vacuum pump 81 can be started. The vacuum pump 81 draws the gas in the mixing tank 2 into the outlet pipe 83 through the coil 86 and the vacuum pipe 82 and then enters the stuffing tank 84. Since the rotating rod 51 rotates clockwise when the mixing tank 2 is stirred, the cam 63 also rotates clockwise to continuously control the spring pressure plate 73 to repeatedly squeeze the air bag 72. The squeezed gas will enter the stuffing tank 84 through the inlet pipe 74. The gas can increase the flow of the stuffing in the stuffing tank 84 to ensure that the stuffing and the exhaust gas can be fully mixed and processed, and the treated gas is discharged from the discharge pipe 85.
