Description

Technical Field

[0001] This utility model relates to the field of silicone resin production technology, specifically to a heating device for producing organosilicon resin. Background Technology

[0002] Silicone resin is a thermosetting polysiloxane polymer with a highly cross-linked structure. It possesses the dual characteristics of both organic resins and inorganic materials, exhibiting unique physical and chemical properties, excellent electrical insulation, temperature resistance, and water resistance. A search revealed an existing technology (publication number: CN202420773212.2) for a heating device in the production of organosilicon resin. The document describes that "this utility model, by setting up a heating unit, a stirring plate, and a rotating shaft, can activate the heating unit. At this time, the compressed air output from the air compressor in the heating unit is filtered by an air dehumidifier and then delivered to the air heater for heating. It is then delivered through the tubular structure of the rotating shaft and connecting pipe to the hollow part of the stirring plate, and dry hot air can be sprayed out through the air outlet holes opened on the stirring plate, thereby heating the silicone resin in the heating tank, achieving the purpose of rapid and uniform heating of the silicone resin in the heating tank." However, in the existing technology, the hot air sprayed from the stirring plate holes needs to undergo heating, filtration, and dehumidification treatment before entering the heating tank, resulting in high energy consumption of the silicone resin heating device. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a heating device for the production of silicone resin is provided to solve the problem that the hot gas ejected from the surface of the stirring plate must be heated, filtered and dehumidified before entering the heating tank, resulting in high energy consumption of the silicone resin heating device.

[0004] To achieve the above objectives, a heating device for the production of organosilicon resin is provided, comprising: a silicone resin heating tank, wherein a stirrer is installed inside the silicone resin heating tank.

[0005] The inner wall of the silicone resin heating tank is welded with a heat transfer plate. The inner side of the heat transfer plate has a heat transfer inlet chamber and a heat transfer outlet chamber. The side end of the heat transfer inlet chamber is connected to the heat transfer outlet chamber through a connecting chamber. A flow guide pipe is embedded and fixed inside the silicone resin heating tank. Two flow dividers are installed on the outer end face of the silicone resin heating tank. The heat transfer plate is connected to the flow dividers through the flow guide pipe. The lower end of the flow dividers is connected to a steam output pipe and a steam delivery pipe, respectively.

[0006] Furthermore, the silicone resin heating tank has a feed inlet on its upper surface, and a stirring motor is fixed on the upper surface of the silicone resin heating tank; and the feed inlet is located at the left end of the stirring motor.

[0007] Furthermore, a controller is provided on the right side of the stirring motor, and a discharge port is provided on the lower end face of the silicone resin heating tank, with a plug inserted inside the discharge port.

[0008] Furthermore, a temperature display is installed on the front surface of the silicone resin heating tank, and a stirring shaft is connected to the lower end of the stirring motor via a coupling, with a stirrer symmetrically mounted on the stirring shaft.

[0009] Furthermore, the side end of the stirrer contacts the inner wall of the silicone resin heating tank via scraper one, and the upper end of the stirrer contacts the lower surface of the heat transfer plate via scraper two.

[0010] Furthermore, the heat transfer plate has a triangular cross-section; and the heat transfer inlet is located on the inclined surfaces on both sides of the heat transfer plate.

[0011] Furthermore, both the heat transfer inlet and outlet chambers are connected to guide pipes, and the diversion pipes are fixed at the left and rear ends of the silicone resin heating tank, respectively.

[0012] The beneficial effects of this utility model are as follows: The heating device for producing organosilicon resin utilizes multiple heat transfer plates distributed inside the tank. Steam is introduced into the heat transfer inlet chamber of the heat transfer plates on the same horizontal plane through a guide pipe, so that the silicone resin in the mixing tank exchanges heat with the steam in the heat transfer plates. The steam after heat exchange is then discharged from the heat transfer outlet chamber of the heat transfer plates, which facilitates the heating device to heat the silicone resin near the center of the tank. This ensures that the heating device heats the silicone resin evenly and fully, eliminates the need for filtering and dehumidifying the heating medium, reduces energy consumption in the heating process of silicone resin, and lowers the production cost of silicone resin.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4 As shown, this utility model provides a heating device for the production of organosilicon resin, including: a silicone resin heating tank 1, and a stirrer 3 installed inside the silicone resin heating tank 1.

[0020] A heat transfer plate 2 is welded to the inner wall of the silicone resin heating tank 1. A heat transfer inlet chamber 21 and a heat transfer outlet chamber 22 are opened on the inner side of the heat transfer plate 2. The side end of the heat transfer inlet chamber 21 is connected to the heat transfer outlet chamber 22 through a connecting chamber 23. A flow guide pipe 24 is embedded and fixed inside the silicone resin heating tank 1. Two diversion pipes 41 are installed on the outer end face of the silicone resin heating tank 1. The heat transfer plate 2 is connected to the diversion pipes 41 through the flow guide pipes 24. The lower end of the diversion pipes 41 is connected to a steam output pipe 4 and a steam delivery pipe 42, respectively.

[0021] First, pour the silicone resin that needs to be heated into the silicone resin heating tank 1. Then, use an external steam circulation device to deliver steam at a certain temperature into the guide pipe 24 inside the silicone resin heating tank 1 through the steam delivery pipe 42. The steam is then circulated through the guide pipe 24 into the heat transfer inlet chamber 21 and heat transfer outlet chamber 22 of multiple heat transfer plates 2 on the same horizontal plane. Turn on the stirring motor 33 so that the stirring motor drives the silicone resin to come into contact with the heat transfer plates 2, allowing the steam in the heat transfer plate 2 chamber to exchange heat with the silicone resin. The steam after heat exchange is sent back to the steam circulation device through the steam outlet pipe 4 until it is heated to a suitable temperature. Then, pull out the plug 15 at the bottom of the silicone resin heating tank 1 to discharge the heated silicone resin.

[0022] In this embodiment, a feed inlet 11 is provided on the upper surface of the silicone resin heating tank 1, and a stirring motor 33 is fixed on the upper surface of the silicone resin heating tank 1; the feed inlet 11 is located at the left end of the stirring motor 33. A controller 12 is provided on the right side of the stirring motor 33, and a discharge port 13 is provided on the lower end face of the silicone resin heating tank 1, with a plug 15 inserted inside the discharge port 13.

[0023] In a preferred embodiment, controller 12 is used to control the stirring speed inside the silicone resin heating tank 1. Discharge port 13 is used to discharge the uniformly heated silicone resin, allowing the heated silicone resin to proceed to the next production process.

[0024] In this embodiment, a temperature display 14 is installed on the front surface of the silicone resin heating tank 1. The lower end of the stirring motor 33 is connected to a stirring shaft 35 via a coupling 34. A stirrer 3 is symmetrically mounted on the stirring shaft 35. The side end of the stirrer 3 contacts the inner wall of the silicone resin heating tank 1 via a scraper 31, and the upper end of the stirrer 3 contacts the lower surface of the heat transfer plate 2 via a scraper 32.

[0025] In a preferred embodiment, the temperature display 14 conveniently displays the temperature value inside the tank. The stirrer 3 is driven to rotate by the stirring motor 33, so that the scraper 1 31 and scraper 2 32 scrape off and discharge the silicone resin on the inner wall of the silicone resin heating tank 1 and the lower surface of the heat transfer plate 2.

[0026] In this embodiment, the heat transfer plate 2 has a triangular cross-section; and the heat transfer inlet chamber 21 is located on the inclined surfaces on both sides of the heat transfer plate 2. The heat transfer inlet chamber 21 and the heat transfer outlet chamber 22 are both connected to the side ends of the guide pipe 24, and the diversion pipe 41 is fixed at the left and rear ends of the silicone resin heating tank 1, respectively.

[0027] As a preferred embodiment, the triangular heat transfer plate 2 facilitates the downward flow of silicone resin within the tank along the slope, reducing silicone resin residue. The steam flowing within the heat transfer inlet chamber 21 and heat transfer outlet chamber 22 exchanges heat with the silicone resin being stirred on the outside through the thermal conductivity of the heat transfer plate 2, achieving indirect heating of the silicone resin. This eliminates the need for filtration and dehumidification of the heating medium, reducing energy consumption in silicone resin heating and processing, and lowering silicone resin production costs. The guide pipe 24 facilitates interconnection between the heat transfer inlet chambers 21 and heat transfer outlet chambers 22 of multiple heat transfer plates 2 on the same horizontal plane, allowing steam to flow within the chambers of multiple heat transfer plates 2 on the same horizontal plane. The diversion pipe 41 facilitates the introduction of steam into the steam circulation equipment and into the guide pipe 24 within the silicone resin heating tank 1.

[0028] This invention provides a heating device for the production of organosilicon resin. It effectively solves the problem in the prior art where the hot gas ejected from the stirring plate hole surface needs to be heated, filtered, and dehumidified before entering the heating tank, resulting in high energy consumption of the silicone resin heating device. It facilitates the heating device to heat the silicone resin near the center of the tank, ensuring uniform and sufficient heating of the silicone resin. It eliminates the need for filtering and dehumidifying the heating medium, reduces energy consumption in the silicone resin heating process, and lowers the production cost of silicone resin. It is suitable for heating devices used in the production of organosilicon resin.
