Description

Technical Field

[0001] This utility model relates to the field of dimethyl silicone oil production technology, and in particular to a purification device for dimethyl silicone oil. Background Technology

[0002] In the purification process of dimethyl silicone oil, catalysts and additives are required to improve the purity of dimethyl silicone oil. During the addition of additives, the raw materials need to be mixed. However, the high viscosity of dimethyl silicone oil makes it easy for the raw materials to accumulate at the bottom, resulting in uneven mixing. Furthermore, when the high-viscosity dimethyl silicone oil is added to the top, the raw materials adhering to the inner wall cannot react effectively with the additives, thus reducing the purity of the dimethyl silicone oil.

[0003] Existing mixing equipment typically mixes dimethyl silicone oil and catalyst directly using centrifugal force. However, this results in the dimethyl silicone oil and catalyst adhering to the inner wall of the container, leading to uneven mixing. Therefore, a dimethyl silicone oil purification device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a purification device for dimethyl silicone oil. This device can solve the problem that some existing stirring equipment usually mixes dimethyl silicone oil and catalyst directly through centrifugal force, which results in the phenomenon that dimethyl silicone oil and catalyst adhere to the inner wall of the container, thus causing uneven mixing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purification device for dimethyl silicone oil, comprising a base plate, wherein an mounting plate and a support plate are fixedly connected to the base plate;

[0006] A mixing tank is rotatably connected to the mounting plate, and a bearing is fixedly connected to the support plate. The mixing tank is fixedly connected to the inner ring of the bearing.

[0007] The first motor and the second motor are fixedly connected to the mounting plate;

[0008] The mixing tank is fixedly connected to an inlet and outlet pipe, and valves are installed on the inlet and outlet pipe;

[0009] A water inlet pipe is rotatably connected to the center of the end of the mixing tank away from the mounting plate, and the water inlet pipe is connected to the external water supply equipment.

[0010] The mixing tank is equipped with a stirring mechanism.

[0011] Preferably, the stirring mechanism includes a gear ring, which is fixedly connected to the outside of the mixing tank, and a gear is fixedly connected to the output end of the second motor;

[0012] The gear and the gear ring are meshed and connected;

[0013] The stirring mechanism further includes a stirring shaft, which is rotatably connected inside the mixing barrel, and stirring rods are fixedly connected to the surface of the stirring shaft;

[0014] The stirring shaft is fixedly connected to the output end of the first motor.

[0015] Preferably, the stirring rod is in a cross shape.

[0016] Preferably, a scraper in an "L" shape is fixedly connected to the stirring shaft, and the scraper is in contact with the inner wall of the mixing barrel.

[0017] Preferably, spray holes are formed in the scraper, a sealing block is slidably connected inside the spray holes, a support rod is slidably connected to the sealing block, and the support rod is fixedly connected to the inner wall of the scraper.

[0018] Preferably, both the sealing block and the spray holes are in an inverted horn shape.

[0019] Preferably, a spring is movably sleeved on the support rod, and both ends of the spring are fixedly connected to the surface of the support rod and the sealing block respectively.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] (1). For this dimethyl silicone oil purification device, when the second motor drives the mixing barrel, the first motor is synchronously started. The output end of the first motor drives the stirring shaft and the stirring rods to rotate together. Since the mixing barrel rotates through the meshing of the gear ring and the gear, the rotation direction of the mixing barrel is opposite to the rotation direction of the stirring shaft. Therefore, it can avoid the phenomenon that dimethyl silicone oil and catalyst adhere to the inner wall of the mixing barrel caused by the centrifugal force, thus ensuring its mixing effect. At the same time, the stirring rods can play the role of secondary stirring, so as to avoid the precipitation phenomenon of the catalyst and dimethyl silicone oil caused by the static state of the traditional mixing barrel, and further avoid the phenomenon of uneven mixing, thus ensuring the purification effect.

[0022] (2). For this dimethyl silicone oil purification device, when the mixing barrel needs to be cleaned, water can be injected into the scraper through the water supply device outside through the water inlet pipe and the stirring shaft. At this time, under the action of the water pressure, the sealing block slides, so it no longer seals the spray holes, and thus a certain gap is generated between the two. At this time, the water sprays out through the spray holes, thus playing the role of flushing the mixing barrel, so that the mixing barrel is more convenient and fast to clean.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Please see Figure 1-4, the utility model provides a technical solution: a purification device for dimethyl silicone oil, including a bottom plate 1, on which an installation plate 2 and a support plate 17 are fixedly connected;

[0034] A mixing barrel 5 is rotatably connected to the installation plate 2, a bearing 7 is fixedly connected to the support plate 17, and the mixing barrel 5 is fixedly connected to the inner ring of the bearing 7;

[0035] A first motor 3 and a second motor 4 are fixedly connected to the installation plate 2;

[0036] A feeding and discharging pipe 18 is fixedly connected to the mixing barrel 5, and a valve is arranged on the feeding and discharging pipe 18;

[0037] A water inlet pipe 6 is rotatably connected to the center of the end of the mixing barrel 5 far from the installation plate 2, and the water inlet pipe 6 is interconnected with an external water supply device;

[0038] A stirring mechanism is arranged on the mixing barrel 5;

[0039] When it is necessary to purify dimethyl silicone oil, the catalyst and dimethyl silicone oil can be put into the interior of the mixing barrel 5 through the feeding and discharging pipe 18 together. Subsequently, the dimethyl silicone oil and the catalyst inside the mixing barrel 5 are mixed and stirred through the stirring mechanism, thereby improving the purity of dimethyl silicone oil through the catalyst;

[0040] Furthermore, the stirring mechanism includes a gear ring 8, the gear ring 8 is fixedly connected to the outside of the mixing barrel 5, and a gear 9 is fixedly connected to the output end of the second motor 4;

[0041] The gear 9 and the gear ring 8 are meshed;

[0042] When the second motor 4 is started, the gear 9 drives the whole mixing barrel 5 to rotate through meshing with the gear ring 8. Therefore, it avoids the precipitation phenomenon of the dimethyl silicone oil and the catalyst inside the mixing barrel 5, ensures their uniform mixing, and thus ensures the purification effect of dimethyl silicone oil;

[0043] Furthermore, the stirring mechanism further includes a stirring shaft 10, the stirring shaft 10 is rotatably connected to the interior of the mixing barrel 5, and stirring rods 11 are fixedly connected to the surface of the stirring shaft 10;

[0044] The stirring rod 11 is in the shape of a Chinese character 'feng';

[0045] The stirring shaft 10 is fixedly connected to the output end of the first motor 3;

[0046] When the second motor 4 drives the mixing tank 5, the first motor 3 is started synchronously. The output end of the first motor 3 drives the stirring shaft 10 and the stirring rod 11 to rotate together. Since the mixing tank 5 rotates through the meshing of the gear ring 8 and the gear 9, the rotation direction of the mixing tank 5 is opposite to that of the stirring shaft 10. This can avoid the phenomenon of dimethyl silicone oil and catalyst not adhering to the inner wall of the mixing tank 5 caused by centrifugal force, thus ensuring its mixing effect. At the same time, the stirring rod 11 can play the role of stirring again, thus avoiding the precipitation of catalyst and dimethyl silicone oil caused by the static state of the traditional mixing tank 5, thus avoiding the phenomenon of uneven mixing, thus ensuring the purification effect.

[0047] Furthermore, an "L"-shaped scraper 12 is fixedly connected to the stirring shaft 10, and the scraper 12 is in contact with the inner wall of the mixing tank 5.

[0048] When the stirring shaft 10 rotates, the scraper 12 rotates together. Therefore, the scraper 12 can clean the inner wall of the mixing tank 5, thereby preventing dimethyl silicone oil from adhering to its inner wall and thus avoiding resource waste. At the same time, it can achieve the effect of cleaning the mixing tank 5.

[0049] Furthermore, the water inlet pipe 6 is internally connected to the stirring shaft 10, and the scraper 12 is internally connected to the stirring shaft 10.

[0050] The scraper 12 has a spray hole 13, and a sealing block 14 is slidably connected inside the spray hole 13. A support rod 15 is slidably connected to the sealing block 14, and the support rod 15 is fixedly connected to the inner wall of the scraper 12.

[0051] A spring 16 is movably sleeved on the support rod 15, and the two ends of the spring 16 are fixedly connected to the surface of the support rod 15 and the sealing block 14, respectively.

[0052] Both the sealing block 14 and the spray hole 13 are inverted trumpet shapes;

[0053] When the mixing tank 5 needs to be cleaned, water can be injected into the scraper 12 through the water inlet pipe 6 and the stirring shaft 10 via an external water supply device. Under the pressure of the water, the sealing block 14 slides under force, thus no longer sealing the spray hole 13, resulting in a certain gap between the two. At this time, the water is sprayed out through the spray hole 13, thereby achieving the effect of rinsing the mixing tank 5, making the cleaning of the mixing tank 5 more convenient and quick.

[0054] Working principle: When the second motor 4 starts, the gear 9 drives the mixing tank 5 to rotate by meshing with the gear ring 8. This avoids the precipitation of dimethyl silicone oil and catalyst inside the mixing tank 5, ensuring that they can be mixed evenly, thus ensuring the purification effect of dimethyl silicone oil.

[0055] When the second motor 4 drives the mixing tank 5, the first motor 3 is started synchronously. The output end of the first motor 3 drives the stirring shaft 10 and the stirring rod 11 to rotate together. Since the mixing tank 5 rotates through the meshing of the gear ring 8 and the gear 9, the rotation direction of the mixing tank 5 is opposite to that of the stirring shaft 10. This avoids the phenomenon of dimethyl silicone oil and catalyst not adhering to the inner wall of the mixing tank 5 due to centrifugal force, thus ensuring the mixing effect. At the same time, the stirring rod 11 can play the role of stirring again, thus avoiding the precipitation of catalyst and dimethyl silicone oil caused by the static state of the traditional mixing tank 5, thus avoiding the phenomenon of uneven mixing, thus ensuring the purification effect.

[0056] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
