It should be noted that the following embodiments are the best and preferred embodiments, and other alternative ways can also be used by those skilled in the art to implement some known technologies; and the drawings are only used to more specifically describe the embodiments, and are not intended to specifically limit the present application.

[0044] As Figures 1 to 8 shown, the printing and dyeing auxiliary stirring processing device and the use method thereof provided by the embodiments of the present application include a rack 1, a fixed block 2 is fixedly connected to the inner side of the rack 1, and a waste gas treatment mechanism 3 is installed through the fixed block 2; the waste gas treatment mechanism 3 includes a heat preservation barrel 31 fixedly connected with the fixed block 2, and a mixing barrel 4 is fixedly connected inside the heat preservation barrel 31, a sealing cover 41 is sealingly placed on the top of the mixing barrel 4, and a hydraulic rod 5 for supporting the sealing cover 41 is fixedly connected to the top of the rack 1; a stirring mechanism 6 for mixing materials is arranged inside the mixing barrel 4, and a magnetic attraction mechanism 7 cooperating with the stirring mechanism 6 is arranged on the outer surface of the mixing barrel 4;

[0045] The stirring mechanism 6 includes a rotating rod 64 arranged inside the mixing barrel 4, a plurality of stirring rods 65 are fixedly connected to the outer surface of the rotating rod 64, and a positive magnetic block 66 is fixedly connected to one end of the rotating rod 64; the magnetic attraction mechanism 7 includes a second annular pipe 71 arranged on the outer surface of the mixing barrel 4, a second sleeve seat 72 is fixedly connected to the front and rear sides of the outer circular surface of the second annular pipe 71, a U-shaped seat 73 is slidingly connected to one side of the outer circular surface of the second annular pipe 71, and a first servo motor 74 is fixedly connected to the outer side of the U-shaped seat 73; a negative magnetic block 75 is fixedly connected to the output shaft of the first servo motor 74 through the U-shaped seat 73, the negative magnetic block 75 is driven to rotate by the first servo motor 74, and the rotating rod 64 is driven to rotate by the positive magnetic block 66, so that the stirring rods 65 can stir and mix the materials.

[0046] As Figures 1 to 8As shown, the stirring mechanism 6 further comprises a first annular pipe 62 arranged at the top of the mixing barrel 4, the front and rear sides of the first annular pipe 62 are provided with a first sleeve 61 fixedly connected with the inner wall of the mixing barrel 4, the left and right sides of the first annular pipe 62 are provided with a T-shaped sleeve 63, and a rotating rod 64 is rotatably connected in the T-shaped sleeve 63; the mixing barrel 4, the first annular pipe 62 and the second annular pipe 71 are all made of stainless steel, and the positive magnetic block 66 and the negative magnetic block 75 are both strong magnetic blocks.

[0047] In order to solve the problem that the traditional stirring device is prone to failure due to the mechanical shaft seal in the corrosive and high-permeability environment, resulting in material leakage, equipment corrosion and environmental pollution, the above technical scheme is used to solve the problem. The above technical scheme mainly comprises a waste gas treatment mechanism 3, a mixing barrel 4, a stirring mechanism 6 and a magnetic attraction mechanism 7. When in use, the first servo motor 74 in the magnetic attraction mechanism 7 is started to drive the negative magnetic block 75 on the output shaft to rotate. Due to the magnetic coupling effect, the positive magnetic block 66 fixed to one end of the rotating rod 64 will rotate synchronously, thereby driving the rotating rod 64 to rotate in the T-shaped sleeve 63 and making the stirring rod 65 stir the material in the mixing barrel 4. The torque is transmitted through the wall of the mixing barrel 4 during the entire driving process, which completely isolates the power components from the material in a physical way, thereby avoiding the medium leakage problem caused by shaft seal wear and corrosion. It is especially suitable for processing corrosive and high-permeability printing and dyeing auxiliaries. When it is necessary to clean or add material in the mixing barrel 4 regularly, the hydraulic rod 5 is only needed to be started to make it retract, thereby realizing the quick opening and closing of the mixing barrel 4. For this operation, not only is the input of the material and the cleaning and maintenance of the device facilitated, but also the tight fit between the sealing cover 41 and the top of the mixing barrel 4 during work is ensured, so that the entire stirring process is in a good sealed state, further ensuring that no leakage and volatilization occurs. For the cleaning of the mixing barrel 4, only cleaning liquid needs to be injected into the interior to dissolve the internal material, thereby completing the cleaning of the inner wall of the mixing barrel 4, so as to ensure the normal mixing of the material next time.

[0048] As shown in Figures 1 to 8 The bottom of the mixing barrel 4 is provided with a driving mechanism 8 for supporting the U-shaped seat 73. The driving mechanism 8 comprises a tray seat 81 arranged at the bottom of the mixing barrel 4 and fixedly connected with the rack 1. A limiting disc 86 is rotatably connected in the interior of the tray seat 81. A supporting disc 85 is fixedly connected to the upper surface of the limiting disc 86. An arc-shaped support 88 for supporting the magnetic attraction mechanism 7 is fixedly connected to one side of the supporting disc 85. The other side is provided with an auxiliary frame 89 sleeved with the second annular pipe 71, so as to maintain the balance of the supporting disc 85.

[0049] As shown in Figures 1 to 8As shown, the driving mechanism 8 further comprises a No. L bracket 82 fixedly connected to one side of the support disc 85, the tray seat 81 is fixedly connected with a second servo motor 83 through the No. L bracket 82, the output shaft of the second servo motor 83 is fixedly connected with a main gear 84, and the upper side of the support disc 85 is fixedly connected with a driven gear 87 meshingly connected with the main gear 84.

[0050] When the driving force of the first servo motor 74 is utilized to drive the negative magnetic block 75 to rotate the positive magnetic block 66, so that the stirring rod 65 fully stirs the materials in the mixing barrel 4, at the same time, the arc-shaped bracket 88 provides stable radial support for the U-shaped seat 73 bearing the first servo motor 74, ensuring the overall rigidity of the magnetic force driving unit during operation, preventing it from being deviated or vibrating due to stress, and ensuring the transmission stability; and when it is necessary to adjust the acting position of the stirring rod 65 in the mixing barrel in real time and accurately according to the physical properties such as viscosity and density of the materials to optimize the flow field, the second servo motor 83 can be started to drive the output shaft to rotate the main gear 84, which drives the driven gear 87 to rotate synchronously through gear meshing, and since the driven gear 87 is fixedly connected with the support disc 85, the power is transmitted to the support disc 85 and the limiting disc 86 integrally connected at the bottom of the support disc 85, so that the two stably rotate in the internal groove of the tray seat 81; during this operation process, the tray seat 81 not only bears all the support functions, but also forms precise rotation guiding and limiting cooperation with the limiting disc 86, effectively preventing the support disc 85 from being deviated or radially shaken in the rotating process, ensuring the accuracy and reliability of the rotating movement; with the rotation of the support disc 85, the arc-shaped bracket 88 and the auxiliary frame 89 fixed thereto make a circular motion, and the arc-shaped bracket 88 pushes the U-shaped seat 73 to slide along the track of the No. 2 annular pipe 71, and since the position of the U-shaped seat 73 changes, the circumferential position of the negative magnetic block 75 thereon relative to the mixing barrel 4 changes, and through magnetic coupling, this external circumferential position change forces the internal positive magnetic block 66 and the rotating rod 64 and the T-shaped sleeve 63 connected therewith to revolve around the No. 1 annular pipe 62 as a whole, thereby finally changing the absolute positions of all the stirring rods 65 in the barrel; this operation process enables the operator to flexibly adjust the position of the magnetic force driving according to the viscosity, density and other properties of the materials, thereby optimizing the stirring flow field and enhancing the adaptability to different materials, ensuring that solid powders or high-viscosity slurries can be uniformly and efficiently mixed, and solving the problem of dead angle that may exist in the traditional fixed-position stirring.

[0051] As Figures 1 to 8As shown, the bottom of the mixing barrel 4 is fixedly connected with a discharge hopper 42, the inside of the discharge hopper 42 is provided with a sealing mechanism 9 for controlling the discharge, the sealing mechanism 9 comprises a blocking ball 91 arranged at the inner top of the discharge hopper 42, the upper surface of the support disc 85 is fixedly connected with a No. 2 L-shaped support 93 near one side of the arc-shaped support 88, one side of the inner bottom of the No. 2 L-shaped support 93 is fixedly connected with a third servo motor 94, the output end of the third servo motor 94 is fixedly connected with a lead screw 95, one side of the upper surface of the No. 2 L-shaped support 93 is fixedly connected with a limiting frame 96, the top of the lead screw 95 is slidingly connected with a nut seat 97, and one side of the nut seat 97 is fixedly connected with a U-shaped rod 98 for supporting the blocking ball 91, and the top of the blocking ball 91 is fixedly connected with symmetrical limiting rods 92.

[0052] As shown in the figure, Figures 1 to 8 The upper end of the discharge hopper 42 is a hollow cylinder, and the lower end is an outwardly expanding hollow cone; the outer diameter of the blocking ball 91 is the same as the diameter of the inner top of the discharge hopper 42, and the blocking ball 91 is made of stainless steel.

[0053] To solve the problem of corrosion of traditional mixing device discharge valve sealing not strict easily leading to leakage of corrosive material, and waste and cross contamination caused by residual material in the valve port after discharge; when the mixing is completed and the material needs to be discharged, the third servo motor 94 is started to drive the lead screw 95 to rotate, driving the nut seat 97 cooperating with it to move downward along the guide of the limiting frame 96, and the nut seat 97 drives the blocking ball 91 to descend synchronously through the U-shaped rod 98, so that it is separated from the cylindrical sealing seat at the top of the discharge hopper 42, thereby opening the discharge channel, and the material is discharged smoothly through the expanded cone at the lower end of the discharge hopper 42 by gravity; after the discharge is completed, the third servo motor 94 is reversed to drive the blocking ball 91 to rise accurately until the spherical surface of the blocking ball 91 and the cylindrical orifice at the inner top of the discharge hopper 42 form a tight linear contact seal again; in this operation process, the spherical surface linear contact sealing form of the blocking ball 91 and the cylindrical orifice is used, compared with the traditional flat valve, the sealing contact is more tight, and it is not sensitive to trace wear, and the blocking ball 91 is made of stainless steel, which has strong corrosion resistance, can ensure that the discharge port is always in an absolutely sealed state when dealing with corrosive and highly permeable printing and dyeing auxiliaries for a long time, thereby avoiding the leakage of the discharge valve; and through the combination of the third servo motor 94 and the lead screw 95, the lifting stroke and speed of the blocking ball 91 can be accurately controlled, thereby realizing fine adjustment of the discharge flow, avoiding the splashing or pipe blockage caused by the traditional valve opening instantaneously; and the shape of the blocking ball 91 is spherical, so that the surface is not easy to hang material, not only reduces the material loss, but also greatly reduces the cross contamination risk between different batches of products, ensuring the purity of the subsequent production products.

[0054] As shown in the figure, Figures 1 to 8As shown, the inner bottom of the mixing barrel 4 is provided with a scraping mechanism 10 matched with the blocking ball 91, the scraping mechanism 10 comprises a third annular pipe 101 arranged at the bottom of the first annular pipe 62, the front and rear sides of the inner wall of the mixing barrel 4 are both provided with a third sleeve seat 102 fixedly connected with the third annular pipe 101, the top of the blocking ball 91 is sleeved with an annular sleeve frame 103, the center of the annular sleeve frame 103 is a semicircular ball cover, and the inside of the semicircular ball cover is provided with a limiting hole matched with the limiting rod 92; the two sides of the annular sleeve frame 103 are both fixedly connected with a scraper 104, and the top of the scraper 104 is provided with a sleeve pipe 105 in sleeved connection with the third annular pipe 101.

[0055] As shown in the figure, Figures 1 to 8 The material of the scraper 104 is stainless steel, and it is in an arc shape, and the cleaning end is attached to the inner wall of the mixing barrel 4.

[0056] To solve the problem that viscous or corrosive materials are easily attached to the inner wall of the mixing barrel 4 after the dyeing and printing auxiliaries are stirred and processed, causing waste of raw materials, difficulty in cleaning, and cross-contamination of different batches of products; when the third servo motor 94 drives the blocking ball 91 to move up and down to close the discharge port, the limiting rod 92 fixed on the top of the blocking ball 91 will drive the annular sleeve 103 sleeved thereon, so that the annular sleeve 103 and the blocking ball 91 become an integral whole, that is, during the movement of the blocking ball 91, the annular sleeve 103 also moves; when the blocking ball 91 has blocked the discharge port, the limiting rod 92 is inserted into the annular sleeve 103, and the operation of the third servo motor 94 is immediately stopped to ensure that the discharge port does not leak; then the second servo motor 83 of the driving mechanism 8 is started, and the gear engagement drives the support disc 85 to rotate, so that the No. 2 L bracket 93 fixedly connected thereto rotates, thereby rotating the entire sealing mechanism 9, and in this process, the annular sleeve 103 is driven to rotate by the blocking ball 91, thereby making the scraping plates 104 fixedly connected on both sides of the annular sleeve 103 rotate along the inner wall of the barrel of the mixing barrel 4; because the arc-shaped cleaning end of the scraping plate 104 tightly scrapes the barrel wall, the sleeve pipe 105 at the top of the scraping plate 104 slides along the fixed No. 3 annular pipe 101, thereby providing stable radial support and guidance for the scraping movement, ensuring smooth and comprehensive scraping action; in the above operation process, the cooperation of the driving mechanism 8 and the sealing mechanism 9 makes the scraping plate 104 clean the residual material on the inner wall of the mixing barrel 4, effectively scraping off the residual paste and slurry adhered to the inner wall, so that it is discharged together with the main material flow, significantly improving the utilization rate of the material and reducing waste; and when the blocking ball 91 completely blocks the discharge port and the material is mixed and stirred, the driving force of the driving mechanism 8 can also be used to make the blocking ball 91 drive the annular sleeve 103 to rotate through the limiting rod 92, so that the scraping plate 104 not only has a cleaning effect when cleaning the material, but also can further improve the material mixing by rotating the scraping plate 104 when mixing the material, thereby greatly improving the material mixing effect.

[0057] As shown in Figures 1 to 8 The waste gas treatment mechanism 3 also includes a supporting plate 34 fixedly connected to one side of the rack 1, an air pump 35 fixedly connected above the supporting plate 34, an air suction pipe 36 fixedly communicated with the sealing cover 41 at one end of the air pump 35, and a conveying pipe 37 fixedly communicated with the heat preservation barrel 31 at the other end of the air pump 35; a discharge pipe 33 is fixedly communicated with one side of the bottom of the heat preservation barrel 31, and a material filling pipe 32 is fixedly communicated with the front side of the upper end of the heat preservation barrel 31.

[0058] To solve the problem of direct emission of toxic and irritating waste gas generated during the stirring process of printing and dyeing auxiliaries (especially containing volatile components such as ammonia water and glacial acetic acid), which leads to deterioration of working environment, harm to personnel health and air pollution, before stirring the volatile material, a specific waste gas absorption liquid (such as dilute acid liquid for absorbing ammonia gas and dilute alkali liquid for absorbing acid mist) can be injected through the filling pipe 32 at the upper end of the heat preservation barrel 31. After starting the stirring, the air pump 35 installed on the supporting plate 34 is started. The air pump 35 continuously extracts the generated volatile gas from the top space of the mixing barrel 4 below the sealing cover 41 through the air extraction pipe 36, and then the volatile gas is transported to the absorption liquid in the heat preservation barrel 31 through the delivery pipe 37 for bubbling or washing. After that, the harmful components (such as NH3 and CH3COOH vapor) in the waste gas are neutralized and fixed by chemical reaction with the absorption liquid, and then the purified gas is discharged through the filling pipe 32 or further treated. When the absorption liquid is saturated, the waste liquid can be discharged through the discharge pipe 33 at the bottom of the heat preservation barrel 31, and fresh absorption liquid can be supplemented through the filling pipe 32. When dilute acid liquid is used to neutralize ammonia gas, it will generate a certain temperature, which will raise the temperature of the reaction liquid in the heat preservation barrel 31, so that the heat is transferred to the mixing barrel 4, thereby increasing the stirring temperature of the material in the mixing barrel 4, and further improving the dissolution efficiency of the material. The combination of active extraction by the air pump 35 and the sealing cover 41 forms a micro-negative pressure in the mixing barrel 4, which ensures that the volatile waste gas is captured and taken away immediately after its generation, avoiding its escape into the workshop environment, and solving the problem of air pollution caused by traditional open or simple ventilation stirring. The heat preservation barrel 31 as an independent external reaction container, the absorption liquid in it can be selected and replaced according to the chemical properties (acidic or basic) of the stirring auxiliary in this round, for example, dilute acid is poured in when dealing with alkaline waste gas (ammonia gas), and dilute alkali is poured in when dealing with acidic waste gas (acetic acid vapor), so that the whole device has stronger practicality and can safely and efficiently deal with various complex auxiliary production formulas.
