[0023] The production efficiency of silicone oil is affected by two factors: output and yield. The silicone oil stirred tank, as a key equipment for silicone oil production, mainly includes a tank body 1000, a stirring rod 2000, and a sealing connection device 3000. The stirring rod 2000 is axially rotatably installed in the tank body 1000 and is used to stir and mix silicone oil raw materials. The sealing connection device 3000 is used to seal the connection between the stirring rod 2000 and the tank body 1000. Among them, the stirring and mixing efficiency of the stirring rod 2000 on the silicone oil raw materials will affect the output of the silicone oil, and the debris generated by the rotation of the stirring rod 2000 relative to the tank body 1000 and the debris generated by the sealing connection device 3000 will affect the yield of the silicone oil. Therefore, to improve the production efficiency of the silicone oil, it is necessary to ensure the mixing efficiency of the silicone oil raw materials and to avoid the debris from falling into the silicone oil. To solve the above technical problems, the first aspect of the present application discloses a silicone oil stirred tank with high mixing efficiency, which can effectively reduce the impurities entering the tank body 1000, thereby ensuring the purity of the silicone oil and improving the production efficiency of the silicone oil. The silicone oil stirred tank of the first aspect of the present application will be described in detail below with reference to the accompanying drawings.
[0024] Referring to Figures 1 to 4 As shown in the drawings, the tank body 1000 of the silicone oil stirred tank of the present embodiment defines a container cavity 1100, which is used to store silicone oil raw materials. A top cover 1200 is installed on the top of the container cavity 1100. In order to improve the stirring efficiency of the stirring rod 2000 on the silicone oil raw materials, the stirring rod 2000 includes a central shaft 2100 and a stirring ring 2200. The stirring ring 2200 is arranged on the outer periphery of the central shaft 2100 and is installed in the container cavity 1100. The stirring ring 2200 is spirally arranged along the axis direction of the central shaft 2100. The central shaft 2100 extends upward out of the top cover 1200 and is connected with a driving device 2130. The driving device 2130 is used to drive the central shaft 2100 to rotate axially. The driving device 2130 can adopt a motor. The rotation of the central shaft 2100 drives the stirring ring 2200 to rotate synchronously. By arranging the stirring ring 2200 in a spiral shape, the stirring and mixing efficiency of the stirring rod 2000 on the silicone oil raw materials in the tank body 1000 can be improved, thereby improving the production efficiency of the silicone oil.
[0025] Referring to Figure 1 ,Figures 5 to 7 As shown in the figure, in order to reduce the impurities or debris into the cavity 1100 to contaminate the silicone oil, the sealing connection device 3000 of the embodiment includes a mounting frame 3100, a static ring 3200 and a dynamic ring assembly 3400, the mounting frame 3100 is mounted on the kettle body 1000, the mounting frame 3100 is provided with a central hole 3110 through which the central shaft 2100 passes, the outer periphery of the central hole 3110 is provided with a first ring groove 3120, the opening of the first ring groove 3120 faces upward, and the static ring 3200 is mounted in the first ring groove 3120; the dynamic ring assembly 3400 is sleeved on the central shaft 2100 and is in driving connection with the central shaft 2100, the top end of the dynamic ring assembly 3400 is in sealing connection with the central shaft 2100, and the bottom end of the dynamic ring assembly 3400 extends into the first ring groove 3120 and is in sealing connection with the static ring 3200. The static ring 3200 of the sealing connection device 3000 is arranged in the first ring groove 3120 of the mounting frame 3100, the bottom of the dynamic ring assembly 3400 extends into the first ring groove 3120 and is attached to the static ring 3200, so that the debris generated by the relative rotation of the dynamic ring assembly 3400 and the static ring 3200 can all fall into the first ring groove 3120, the first ring groove 3120 is separated from the central hole 3110, thereby avoiding the debris falling into the kettle body 1000 to affect the purity of the silicone oil, reducing the unqualified rate and improving the production efficiency of the silicone oil.
[0026] Referring to Figures 2 to 4 As shown in the figure, the stirring ring 2200 includes an outer stirring ring 2210 and an inner stirring ring 2220, the central shaft 2100 is provided with a first mounting shaft 2110 extending radially, the outer stirring ring 2210 and the inner stirring ring 2220 are both sleeved on the outer periphery of the central shaft 2100 and are both connected with the first mounting shaft 2110. Referring to Figure 2 As shown in the figure, the outer stirring ring 2210 is spirally arranged along the axial direction of the central shaft 2100 and is connected with the end portion of the first mounting shaft 2110; the inner stirring ring 2220 is also spirally arranged along the axial direction of the central shaft 2100, and the inner stirring ring 2220 is arranged between the outer stirring ring 2210 and the central shaft 2100, and the inner stirring ring 2220 is connected with the middle portion of the first mounting shaft 2110. Through the spiral structure of the outer stirring ring 2210 and the inner stirring ring 2220, the turbulence ability of the stirring rod 2000 can be improved, and at the same time, it is ensured that the raw materials at each position in the cavity 1100 can be fully stirred.
[0027] Further, referring to Figure 2As shown, two outer stirring rings 2210 are provided, and two inner stirring rings 2220 are correspondingly provided, the rotation symmetry angle of the two outer stirring rings 2210 is 180°, and / or the rotation symmetry angle of the two inner stirring rings 2220 is 180°, preferably the rotation symmetry angle of the two outer stirring rings 2210 and the rotation symmetry angle of the two inner stirring rings 2220 are both 180°, and the outer stirring rings 2210 and the inner stirring rings 2220 are arranged with a 90° stagger, so as to achieve a better turbulence effect.
[0028] In the embodiment of the present application, it is further preferred that the rotation directions of the outer stirring rings 2210 and the inner stirring rings 2220 are opposite, so as to Figure 2 For example, if the rotation direction of the outer stirring ring 2210 is defined as clockwise, then the rotation direction of the inner stirring ring 2220 is counterclockwise. That is, if the starting rotation angle of one of the outer stirring rings 2210 is defined as 0°, and the clockwise rotation angle is positive, then the starting rotation angle of the other outer stirring ring 2210 is 180°; correspondingly, if the starting rotation angle of one of the inner stirring rings 2220 is defined as 0°, then the starting rotation angle of the other inner stirring ring 2220 is -180°. The two outer stirring rings 2210 and the two inner stirring rings 2220 are rotationally symmetrical, which increases the structural density of the stirring rod 2000, and further improves the turbulence effect of the stirring rod 2000.
[0029] In the embodiment of the present application, the outer diameter of the outer stirring ring 2210 remains unchanged along the axis direction of the central shaft 2100, and / or the outer diameter of the inner stirring ring 2220 remains unchanged. Specifically, referring to Figure 2 、 Figure 4 As shown, preferably the outer stirring ring 2210 and the inner stirring ring 2220 are both equal-diameter spirals, which can effectively reduce the manufacturing cost and maintenance cost.
[0030] It is conceivable that in actual production, the outer diameter of the outer stirring ring 2210 and the inner stirring ring 2220 can be designed according to the needs; for example, the outer diameter of the outer stirring ring 2210 can gradually increase or gradually decrease along the axis direction of the central shaft 2100, the gradual increase or decrease can be linear increase or decrease or non-linear increase or decrease, or the outer diameter of the outer stirring ring 2210 can increase first and then decrease, or decrease first and then increase, etc. along the axis direction of the central shaft 2100; similarly, the outer diameter of the inner stirring ring 2220 can also increase or decrease along the axis direction of the central shaft 2100, and the specific application can be set according to the actual needs, which is not limited in the embodiment.
[0031] In order to further reduce the manufacturing cost and maintenance cost, the outer stirring ring 2210 and the inner stirring ring 2220 can adopt the same angle ring line, for example, the thickness, width, etc. of the outer stirring ring 2210 and the inner stirring ring 2220 are designed to be equal.
[0032] It should be noted that, as shown in Figure 4 , the outer diameter D1 of the outer stirring ring 2210 and the outer diameter D2 of the inner stirring ring 2220 in the embodiment are preferably related as D2 = 0.3 ~ 0.7D1 to avoid the outer stirring ring 2210 and the inner stirring ring 2220 being too close or too far apart to reduce the mixing effect on the silicone oil raw material.
[0033] In the embodiment of the present application, as shown in Figure 2 , Figure 3 , the central shaft 2100 is also provided with a radially extending second mounting shaft 2120, the first mounting shaft 2110 and the second mounting shaft 2120 are staggered along the axial direction of the central shaft 2100; the outer stirring ring 2210 and the inner stirring ring 2220 are both connected with the second mounting shaft 2120. Specifically, the axial extension direction of the second mounting shaft 2120 is perpendicular to the axial extension direction of the first mounting shaft 2110, and as shown in Figure 2 , the axial length of the second mounting shaft 2120 is substantially equal to the axial length of the first mounting shaft 2110, and the shape and size of the second mounting shaft 2120 are also substantially the same as those of the first mounting shaft 2110, the outer stirring ring 2210 is connected with the end of the second mounting shaft 2120, and the inner stirring ring 2220 is connected with the middle of the second mounting shaft 2120 to reduce the manufacturing cost of the stirring rod 2000.
[0034] It is conceivable that the axial extension direction of the second mounting shaft 2120 is not limited to being perpendicular to the axial extension direction of the first mounting shaft 2110, and the included angle therebetween can also be an acute angle or an obtuse angle. The provision of the second mounting shaft 2120 can improve the stability of the outer stirring ring 2210 and the inner stirring ring 2220, reduce the deformation of the outer stirring ring 2210 and the inner stirring ring 2220 during the stirring process of the stirring rod 2000 of the embodiment, and thus prolong the service life of the stirring rod 2000.
[0035] As shown in Figure 2 , the first mounting shaft 2110 passes through the central shaft 2100, the middle of the first mounting shaft 2110 is welded with the central shaft 2100, and the two ends of the first mounting shaft 2110 are respectively connected with the two outer stirring rings 2210; for ease of understanding, the two ends of the first mounting shaft 2110 extending out of the central shaft 2100 are defined as a first shaft section and a second shaft section with the central shaft 2100 as a boundary, and the two inner stirring rings 2220 are respectively connected with the middle of the first shaft section and the second shaft section. Correspondingly, the second mounting shaft 2120 also passes through the central shaft 2100, the middle of the second mounting shaft 2120 is welded with the central shaft 2100, and the two ends of the second mounting shaft 2120 are respectively connected with the two outer stirring rings 2210.
[0036] In the embodiment of the present application, there are multiple first installation shafts 2110, and the multiple first installation shafts 2110 are evenly spaced along the axis direction of the central axis 2100; and / or, there are multiple second installation shafts 2120, and the multiple second installation shafts 2120 are evenly spaced along the axis direction of the central axis 2100. Specifically, refer to Figure 2 、 Figure 3 As shown, multiple first installation shafts 2110 and second installation shafts 2120 can significantly improve the fixing effect of the outer stirring ring 2210 and the inner stirring ring 2220, thereby improving the stability of the stirring rod 2000, improving the turbulence effect, and extending the service life of the equipment.
[0037] Reference Figure 5 As shown, the sealing connection device 3000 of the present application further includes a fixing ring 3300 , which is mounted on the stirring rod 2000 . The axial rotation of the stirring rod 2000 drives the fixing ring 3300 to rotate synchronously. A first annular groove 3120 is provided on the outer periphery of the center hole 3110 of the mounting frame 3100. The first annular groove 3120 is preferably coaxially arranged with the center hole 3110, and the opening of the first annular groove 3120 faces upward; the fixed ring 3300 is arranged above the first annular groove 3120, and the dynamic ring assembly 3400 is sleeved on the center shaft 2100. The bottom end of the dynamic ring assembly 3400 extends into the first annular groove 3120 to be sealed with the static ring 3200. The top end of the dynamic ring assembly 3400 is connected to the fixed ring 3300 by fasteners, and the inner side wall of the dynamic ring assembly 3400 is sealed with the center shaft 2100; the fasteners can be structures such as bolts, and the inner side wall of the dynamic ring assembly 3400 is sealed with the center shaft 2100 by structures such as sealing rings. The fixing ring 3300 and the central shaft 2100 can be connected by interference fit, keys, bolt fasteners, welding, etc. The fixing ring 3300 cannot rotate or move axially relative to the central shaft 2100.
[0038] Since the top end of the dynamic ring assembly 3400 is connected with the fixed ring 3300 by the fastener, when the fixed ring 3300 rotates synchronously with the stirring rod 2000, the dynamic ring assembly 3400 rotates synchronously around the central shaft 2100, and then the dynamic ring assembly 3400 and the static ring 3200 rotate relatively. The relative rotation between the dynamic ring assembly 3400 and the static ring 3200 will cause abrasion, but since the static ring 3200 is installed in the first ring groove 3120, and the first ring groove 3120 is not in communication with the central hole 3110, the abrasion debris generated by the relative rotation between the dynamic ring assembly 3400 and the static ring 3200 will fall into the first ring groove 3120, and will not fall into the kettle body 1000 through the central hole 3110, thereby avoiding the debris falling into the kettle body 1000 to affect the product quality of the silicone oil. The dynamic ring assembly 3400 and the fixed ring 3300 rotate with the central shaft 2100, so there is no relative motion between the central shaft 2100 and the fixed ring 3300 and the dynamic ring assembly 3400, and there is no debris generated by abrasion, which greatly improves the quality of the silicone oil.
[0039] In the embodiment of the present application, the first ring groove 3120 is used to store liquid medium, such as silicone oil and other medium that is not easy to react with the equipment and corrode the equipment. Generally, the internal pressure of the kettle body 1000 will be greater than the atmospheric pressure, so when the sealing between the bottom end of the dynamic ring assembly 3400 and the static ring 3200 is damaged, the liquid medium stored in the first ring groove 3120 will generate bubbles, and the operating personnel can easily judge whether the sealing between the dynamic ring assembly 3400 and the static ring 3200 is damaged through the bubbles, and then the dynamic ring assembly 3400 or the static ring 3200 can be replaced in time to avoid affecting the quality of the silicone oil due to poor air tightness of the sealing connection device 3000; the liquid medium stored in the first ring groove 3120 can also cool the dynamic ring assembly 3400 and the static ring 3200, reduce the relative friction of the dynamic ring assembly 3400 and the static ring 3200, and avoid damage to the equipment caused by high temperature generated by the relative rotation of the dynamic ring assembly 3400 and the static ring 3200.
[0040] It is conceivable that, in order to facilitate the injection of liquid medium into the first ring groove 3120 and the observation of whether bubbles are generated in the liquid medium, it is preferred that, as shown in Figure 5 , the outer diameter of the first ring groove 3120 is greater than the outer diameter of the dynamic ring assembly 3400.
[0041] In order to avoid too much debris accumulating in the first ring groove 3120, referring to Figure 5 , the first ring groove 3120 of the embodiment includes a first side wall 3122 and a second side wall 3123 arranged oppositely, the first side wall 3122 is arranged close to the central shaft 2100, the second side wall 3123 is arranged away from the central shaft 2100, and the first ring groove 3120 is formed between the first side wall 3122 and the second side wall 3123. Referring to Figure 7As shown, the second side wall 3123 is provided with a flushing port 3124 penetrating through the second side wall 3123, and the flushing port 3124 is preferably arranged at the bottom of the second side wall 3123; the flushing port 3124 is sealed by a sealing plug under normal operation of the device, and when it is necessary to clean the debris in the second annular groove 3416, the sealing plug is pulled out, and the debris in the second annular groove 3416 is taken out through the outflow of the liquid medium in the second annular groove 3416.
[0042] It should be noted that the liquid medium injected into the first annular groove 3120 should not be too much under normal operation of the device, especially should not exceed the height of the first side wall 3122 in the vertical direction, otherwise the liquid medium exceeding the first side wall 3122 will enter the center hole 3110, and then enter the kettle body 1000 through the center hole 3110 to affect the purity of the silicone oil; the liquid medium injected into the first annular groove 3120 can be just above the connection between the static ring 3200 and the dynamic ring assembly 3400, and the specific injection amount is not limited in the embodiment.
