[0025] A resin preheating water circulation system includes a water heating tank 10 mounted on a base 1. A first pump body 20 is connected to the water outlet 11 at the bottom of the water heating tank. The first pump body is connected to the upper part of an insulated storage tank 30 via a water supply pipe 21. A second pump body 40 is connected to the water supply port at the bottom of the insulated storage tank. The second pump body is connected to the hot water inlet 51 of a raw material preheating tank 50 via a water supply pipe 41. The hot water outlet 52 of the raw material preheating tank is connected to the return water port 12 at the top of the water heating tank via a return water pipe 60. A shield 70 is provided above the water heating tank to help reduce the water heating tank from being exposed to sunlight and rain. A shielding device 80 is provided above both the first and second pump bodies to help reduce the first and second pump bodies from being exposed to sunlight and rain.

[0026] In this embodiment, at least two branch outlet pipes 14 are connected to the outlet port of the water heating tank via the main outlet pipe 13. Each branch outlet pipe is equipped with a valve and a first pump body. Each first pump body is connected to an insulated storage tank, and a second pump body is connected to the water supply port at the bottom of each insulated storage tank. This allows one water heating tank to supply water to at least two insulated storage tanks. The heated hot water is stored in the insulated storage tanks and then supplied to the corresponding raw material preheating tanks on the production line via the second pump bodies to heat the raw material preheating tanks for preheating and melting of resin raw materials.

[0027] In this embodiment, the outer wall of the water heating tank is wrapped with an insulation layer 10a to improve the insulation effect. Several electric heating tubes 15, extending through the insulation layer and into the tank body, are installed at intervals along the circumference of the lower part of the water heating tank to heat the water inside. A temperature sensing probe 16, extending into the tank body, is installed on the middle side wall of the water heating tank to detect the water temperature, allowing the controller to control the water temperature. A water supply pipe 17 is installed on the upper side wall of the water heating tank to replenish water. A pressure gauge 18 and a liquid level sensor are also installed on the water heating tank to monitor water pressure and liquid level.

[0028] In this embodiment, a support frame 71 is provided around the water heating tank, and the shield is composed of several corrugated steel sheets and fixed to the top of the support frame. Furthermore, the top-view projection area of ​​the shield is much larger than that of the water heating tank, thereby reducing the time the tank is directly exposed to sunlight and minimizing rain exposure.

[0029] In this embodiment, in order to reduce the exposure of the first pump body and the second pump body to sun and rain, the shielding device includes a fixing frame 81 fixed on the base. The top of the fixing frame is inclined and a cover plate 82 is fixed thereon. The four sides of the cover plate are provided with vertically downward extensions 83, thereby increasing the shielding area.

[0030] In this embodiment, both the cover plate and the extension are made of corrugated steel sheets, which are readily available and have low cost.

[0031] In this embodiment, the insulated storage tank is wrapped with an insulation layer to improve the insulation effect; the first pump body and the second pump body are both centrifugal pumps 20b driven by motor 20a, thereby ensuring the head of the hot water bag.

[0032] In this embodiment, the raw material preheating tank is provided with a jacketed heating chamber 51, and the upper and lower parts of the raw material preheating tank are respectively provided with a hot water outlet 51 and a hot water inlet 52 connected to the jacketed heating chamber, so that the tank body is heated by the hot water outlet and the hot water inlet in conjunction with the jacketed heating chamber.

[0033] In this embodiment, the upper sidewall of the raw material preheating tank is provided with a feed pipe 53 and an air inlet pipe 54 that enter its inner cavity. The feed pipe supplies material into the raw material preheating tank; the air inlet pipe allows inert gas with a certain pressure to pass into the raw material preheating tank, facilitating the discharge of resin material. A discharge pipe 55 is provided at the bottom of the raw material preheating tank, and a stirring shaft 56 driven by a motor installed at the top of the raw material preheating tank is provided inside the tank's inner cavity. The top of the raw material preheating tank is also provided with a sealed feeding port.

[0034] In this embodiment, to ensure the insulation effect, the pipeline between the water outlet at the bottom of the water heating tank and the first pump body, the pipeline between the first pump body and the insulation storage tank, the pipeline between the water supply port of the insulation storage tank and the second pump body, and the outer wall of the return water pipe are all wrapped with an insulation structure.

[0035] If the terms "first" and "second" are used in the above description to define the components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing the components in the description. Unless otherwise stated, the above terms have no special meaning.

[0036] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0037] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.
