Description

Technical Field

[0001] This utility model relates to the field of silicone oil processing technology, and in particular to a twin-shaft mixer for silicone oil processing. Background Technology

[0002] The processing and manufacturing of silicone oil requires the use of reaction vessels. In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process are achieved. Therefore, the cleaning of reaction vessels is a very important issue. Since reaction vessels are generally very large and usually have several openings at the top, excessively large reaction vessels may require manual entry for cleaning, which is not good for human health and poses a certain degree of danger. Smaller reaction vessels are generally cleaned by stirring and agitating devices, but this cleaning method cannot achieve a complete cleaning effect and will leave a lot of substances in the reaction vessel.

[0003] A search revealed that prior art CN208213152U discloses an easy-to-clean reaction vessel for silicone oil processing, relating to the field of silicone oil processing technology. This easy-to-clean silicone oil processing reaction vessel includes a vessel body, with bases fixedly installed on both sides of the bottom of the vessel body. A feeding pipe is installed at the top of the vessel body, and a discharge pipe is installed at the bottom. A motor is fixedly installed at the top of the vessel body, and a first pulley is fixedly installed at the output end of the motor. This easy-to-clean silicone oil processing reaction vessel, through the cooperation of a motor, first pulley, bearing, stirring shaft, second pulley, belt, stirring rod, water pump, water tank, inlet pipe, outlet pipe, spray pipe, and nozzle, achieves cleaning of the inner wall of the vessel body during stirring. The water pump draws water from the water tank and sprays it onto the inner wall of the vessel body through the outlet pipe and nozzle at the bottom of the spray pipe. Compared to traditional silicone oil processing reaction vessels, this silicone oil processing reaction vessel is much easier to clean.

[0004] However, the above equipment has the following problems in actual use: the silicone oil is stirred by a single rotating stirring rod, which is not conducive to rapid and uniform mixing. Utility Model Content

[0005] The purpose of this invention is to provide a twin-shaft mixer for silicone oil processing, which aims to solve the problem that existing equipment uses a single rotating stirring rod for stirring when mixing silicone oil, which is not conducive to rapid and uniform mixing.

[0006] To achieve the above objectives, this utility model provides a twin-shaft mixer for silicone oil processing, including a mixing tank, an upper cover plate at the top of the mixing tank, a feed pipe on the upper cover plate, a lower cover plate at the bottom, and a mixing mechanism;

[0007] The stirring mechanism includes a first motor, an inclined platform, a first rotating shaft, a second motor, a second rotating shaft, a support sleeve, a first stirring device, a second stirring device, and a discharge device. The first motor is fixed to the bottom of the lower cover plate. The inclined platform is integrally formed with the lower cover plate and has a skeleton-type sealing ring installed in the hole that mates with the output shaft of the first motor. The first rotating shaft is connected to the output shaft of the first motor via a coupling. The second motor is fixed to the upper cover plate and is symmetrically arranged, rotating in the opposite direction to the first motor. The second rotating shaft is connected to the output shaft of the second motor via a coupling. The support sleeve is fixedly connected to the upper cover plate and rotatably connected to the stepped shaft at the top of the first rotating shaft. The first stirring device is mounted on the first rotating shaft, the second stirring device is mounted on the second rotating shaft, and the discharge device is located on the side of the stirring tank near the lower point of the inclined platform.

[0008] The first rotating shaft has a wear-resistant coating on the top stepped shaft end surface, which is a titanium oxide coating.

[0009] The first stirring device includes a mounting block and a first stirring plate. The mounting block is detachably connected to the first rotating shaft and multiple sets are arranged vertically at intervals. The first stirring plate is welded and fixed on the mounting block and is arranged symmetrically.

[0010] The second stirring device includes a connecting plate and a second stirring plate. The connecting plate is symmetrically welded to the second rotating shaft. The second stirring plate is welded to the end of the connecting plate away from the second rotating shaft.

[0011] The discharge device includes a connecting pipe and a discharge valve. The connecting pipe is welded inside the discharge port of the mixing tank. The discharge valve is fixedly connected to the connecting pipe and is located on the outlet side of the connecting pipe.

[0012] The stirring mechanism also includes a filter cylinder, which is slidably installed inside the feed pipe and limited by its own limiting plate, and its bottom is a filter screen structure.

[0013] This utility model discloses a twin-shaft mixer for silicone oil processing. During processing, the power supply to the equipment is first turned on, and then silicone oil is put into the mixing tank through the feed pipe. At this time, the discharge device is closed. Then, the first motor can be controlled to drive the first rotating shaft and the first stirring device to stir. At the same time, the second motor can be controlled to drive the second rotating shaft and the second stirring device to rotate in opposite directions. Compared with the traditional equipment that rotates and stirs in one direction, this application is more conducive to the rapid and uniform mixing of silicone oil. The inclined table will facilitate the complete discharge of silicone oil, thereby solving the problem that the existing equipment stirs silicone oil by a single rotating stirring rod, which is not conducive to rapid and uniform mixing.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Example 1:

[0023] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a twin-shaft mixer for silicone oil processing. Figure 2 This is a schematic diagram of the structure of the first stirring plate 112. Figure 3This is a cross-sectional view of the support sleeve 110. This utility model provides a twin-shaft mixer for silicone oil processing: it includes a mixing tank 101, an upper cover plate 102, a feed pipe 103, a lower cover plate 104, and a mixing mechanism. The mixing mechanism includes a first motor 105, an inclined platform 106, a first rotating shaft 107, a second motor 108, a second rotating shaft 109, a support sleeve 110, a first mixing device, a second mixing device, and a discharge device.

The discharge device includes a connecting pipe 115 and a discharge valve 116. This solution solves the problem that existing equipment uses a single rotating mixing rod for mixing silicone oil, which is not conducive to rapid and uniform mixing. Therefore, this solution facilitates rapid and uniform mixing of silicone oil.

[0024] In this embodiment, the mixing tank 101 is provided with an upper cover plate 102 at the top, a feed pipe 103 on the upper cover plate 102, and a lower cover plate 104 at the bottom. The upper cover plate 102 and the lower cover plate 104 are fixed by bolts. Three I-beams are installed at the bottom of the lower cover plate 104 for equipment support. The feed pipe 103 is welded and fixed on the upper cover plate 102.

[0025] The first motor 105 is fixed to the bottom of the lower cover plate 104. The tilting platform 106 is integrally formed with the lower cover plate 104 and has a skeleton-type sealing ring installed in the mating hole with the output shaft of the first motor 105. The first rotating shaft 107 is connected to the output shaft of the first motor 105 via a coupling. The second motor 108 is fixed on the upper cover plate 102 and is symmetrically arranged, rotating in the opposite direction to the first motor 105. The second rotating shaft 109 is connected to the output shaft of the second motor 108 via a coupling. The support sleeve 110 is fixedly connected to the upper cover plate 102 and rotatably connected to the stepped shaft at the top of the first rotating shaft 107. The first stirring device is disposed on the first rotating shaft 107, the second stirring device is disposed on the second rotating shaft 109, and the discharge device is disposed on the side of the mixing tank 101 near the lower point of the tilting platform 106. The first motor 105 and the second motor 108 are fixed by bolts. The output shaft of the first motor 105 is connected to the first rotating shaft 107 via a coupling, and the output shaft of the second motor 108 is connected to the second rotating shaft 109 via a coupling. The tilting platform 106 is integrally mounted on the lower cover plate 104 and has a through hole through which the motor shaft of the first motor 105 passes. A skeleton-type sealing ring is installed in the through hole for sealing to prevent silicone oil leakage. The outlet device is provided on the lower side of the tilting platform 106 for silicone oil discharge. The top of the first rotating shaft 107 is a stepped end, which rotates with the bottom cylinder of the support sleeve 110 to achieve rotational support for the first rotating shaft 107 and improve its stability. The support sleeve 110 is T-shaped and fixed by bolts. The first stirring device and the second stirring device are used for stirring.

[0026] The top stepped end surface of the first rotating shaft 107 is provided with a wear-resistant coating. The wear-resistant coating is a titanium oxide coating.

[0027] Secondly, the mounting block 111 is detachably connected to the first rotating shaft 107, and multiple sets are arranged vertically at intervals; the first stirring plate 112 is welded and fixed to the mounting block 111, and is arranged symmetrically. After the mounting block 111 is fitted onto the first rotating shaft 107, it is fixed by bolts, and the first stirring plate 112 is symmetrically welded to the mounting block 111.

[0028] Then, the connecting plate 113 is symmetrically welded to the second rotating shaft 109; the second stirring plate 114 is welded to the end of the connecting plate 113 away from the second rotating shaft 109. The connecting plate 113 is symmetrically welded to the second rotating shaft 109, and the second stirring plate 114 is welded to the connecting plate 113.

[0029] Finally, the connecting pipe 115 is welded into the discharge port of the mixing tank 101; the discharge valve 116 is fixedly connected to the connecting pipe 115 and located on the outlet side of the connecting pipe 115. The connecting pipe 115 is T-shaped, with its front round end inserted into the outer rear of the outlet of the mixing tank 101 and welded for fixation. The connecting flange of the discharge valve 116 is connected to the connecting flange of the connecting pipe 115 by means of screws and nuts.

[0030] When using this invention to solve the problem that existing equipment uses a single rotating stirring rod for stirring silicone oil, which is not conducive to rapid and uniform mixing, the process involves first connecting the equipment to the power supply, and then adding silicone oil into the mixing tank 101 through the feed pipe 103. At this time, the discharge valve 116 is closed. Then, the first motor 105 can be controlled to drive the first rotating shaft 107 to rotate. The rotation of the first rotating shaft 107 will drive the first stirring plate 112 to rotate for stirring. At the same time, the second motor 108 can be controlled to drive the second rotating shaft 109 to rotate, which will drive the second stirring plate 114 to rotate in the opposite direction to the rotation of the first stirring plate 112. Compared with the single-direction rotation stirring in traditional equipment, this application is more conducive to rapid and uniform mixing of silicone oil. The tilting table 106 will facilitate the complete discharge of silicone oil, thereby solving the problem that existing equipment uses a single rotating stirring rod for stirring silicone oil, which is not conducive to rapid and uniform mixing.

[0031] Example 2:

[0032] like Figure 4 and Figure 5 As shown, where Figure 4 This is a schematic diagram of the overall structure of a twin-shaft mixer for silicone oil processing. Figure 5 This is a cross-sectional view of the filter cylinder 201. Based on the first embodiment, this utility model provides a twin-shaft mixer for silicone oil processing. The mixing mechanism also includes a filter cylinder 201. The filter cylinder 201 is slidably installed inside the feed pipe 103 and is limited by its own limiting plate. Its bottom is a filter screen structure.

[0033] In this embodiment, the filter cartridge 201 can be directly slidably installed inside the feed pipe 103. After installation, it is limited by the top side limiting plate. Since its bottom is a filter screen structure, it can filter when silicone oil is added, reducing silicone oil impurities. When cleaning, it can be directly removed and cleaned.
