Abstract

This utility model discloses a novel casting pulping machine. The machine incorporates a cooling jacket encasing the motor, and two interconnected cooling pipes (one and two) within the mixing tank and cooling jacket. A water pump circulates the coolant through these pipes, dispersing heat from the motor to the mixing tank, improving heat dissipation and allowing the motor to operate continuously for extended periods, thus increasing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of material mixing, and more specifically, it relates to a novel casting pulping machine. Background Technology

[0002] In some pre-casting processes, such as precision casting of ceramic shells, ceramic slurry is needed to make the mold. This requires mixing ceramic powder with binders, catalysts and other auxiliary agents to form a uniform slurry, which requires the use of a slurry mixer.

[0003] Because the slurry used in casting has a certain viscosity, the motor of the slurry machine is prone to overheating after processing it for a long time. Overheating can cause some parts of the motor to age or even deform, reduce the performance of the motor, and shorten its lifespan. Therefore, during the production process, the motor is usually cooled down by intermittent use or frequent shutdowns, which reduces production efficiency to some extent.

[0004] Based on the above, the purpose of this utility model is to provide a new type of casting pulping machine to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a novel casting pulping machine. This invention features a cooling jacket that encloses the motor, and two interconnected cooling pipes, a first cooling pipe and a second cooling pipe, are installed inside the mixing tank and the cooling jacket, respectively. A water pump is then installed to circulate the coolant through the first and second cooling pipes. During the flow of the coolant, the heat from the motor is distributed to the entire mixing tank, resulting in better heat dissipation and allowing the motor to operate continuously for extended periods, thus increasing work efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel casting pulping machine, comprising a mixing tank, wherein the mixing tank is provided with a feed inlet, a discharge pipe, a mixing paddle and a motor, a valve is provided on the discharge pipe, a cooling jacket is provided on the mixing tank to enclose the motor, a circulation pipe one and a circulation pipe two are respectively provided on the mixing tank and the cooling jacket, the circulation pipe one and the circulation pipe two are interconnected and allow liquid to circulate between them, and a water pump is provided between the circulation pipe one and the circulation pipe two.

[0007] By adopting the above technical solution, when the pulping operation is carried out, the user drives the water pump to run, and the water pump drives the coolant to circulate between circulation pipe one and circulation pipe two. During the flow, the coolant exchanges heat with the motor through the cooling jacket, thereby carrying away the heat on the motor and dispersing the heat to the whole body of the mixing tank, so as to improve the heat dissipation effect, allowing the motor to run continuously for a long time and increasing work efficiency.

[0008] The present invention is further configured such that a water tank is provided between the first circulation pipe and the second circulation pipe, and a heater is provided inside the water tank.

[0009] The present invention is further configured such that: temperature sensors are provided on both the motor and the water tank, and a PLC controller is provided on the mixing tank, wherein the PLC controller is electrically connected to the temperature sensors and the heater respectively.

[0010] The present invention is further configured such that both circulation pipe one and circulation pipe two are arranged in a spiral shape.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention features a cooling jacket that encloses the motor, with interconnected cooling pipes 1 and 2 installed inside the mixing tank and cooling jacket. A water pump circulates the coolant through cooling pipes 1 and 2, dispersing heat from the motor throughout the mixing tank for better heat dissipation and allowing the motor to operate continuously for extended periods, thus increasing efficiency. Furthermore, a water tank, heater, temperature sensor, and PLC controller regulate the coolant temperature, thereby controlling the temperature of the motor and mixing tank. This ensures the motor operates at a suitable temperature and prevents the raw materials from becoming too viscous and difficult to mix evenly, further improving pulping efficiency.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] A new type of casting pulping machine, such as Figure 1 As shown, the system includes a mixing tank 1, which has an inlet 4, a discharge pipe 2, a stirring paddle 3, and a motor 5. The discharge pipe 2 is equipped with a valve. A cooling jacket 6, which encloses the motor 5, is installed on the mixing tank 1. The cooling jacket is made of a thermally conductive alloy, such as copper alloy. A first circulation pipe 7 and a second circulation pipe 8 are embedded in the mixing tank 1 and the cooling jacket 6, respectively. Both circulation pipes 7 and 8 are spirally arranged and are interconnected, allowing liquid to circulate between them. A water pump 9 and a water tank 10 are installed between circulation pipes 7 and 8. A heater 11 is installed in the water tank 10. Temperature sensors (not shown in the figure) are installed on both the motor 5 and the water tank 10. A PLC controller (not shown in the figure) is installed on the mixing tank 1. The PLC controller is electrically connected to the temperature sensor and the heater 11.

[0020] Working principle: When pulping is performed, the user drives the water pump 9 to operate. The water pump 9 drives the coolant to circulate between circulation pipe 7 and circulation pipe 8. During the flow, the coolant exchanges heat with the motor 5 through the cooling jacket 6, thereby removing the heat from the motor 5 and distributing the heat around the mixing tank 1. This improves the heat dissipation of the motor 5, allowing it to run continuously for a long time and increasing work efficiency. In the process of cooling the motor, the coolant can also raise the temperature of the raw materials in the mixing tank to a certain extent, preventing the raw materials from becoming too viscous due to low temperature, making it difficult to mix evenly and increasing the burden on the motor. This allows the heat energy of the motor to be utilized.

[0021] During the above process, the PLC controller continuously monitors the temperature of the motor 5 and the coolant using a temperature sensor. The user can pre-set a control program and a preset temperature value within the PLC controller. When the temperature of the motor 5 is lower than the preset value, the PLC controller controls the heater 11 to heat the coolant, thereby raising the temperature of the motor 5 and the mixing tank 1. This prevents the motor 5 from deteriorating due to excessively low temperatures and also prevents the raw materials from becoming too viscous due to low temperatures, making it difficult to mix evenly and increasing the burden on the motor. When the temperature of the motor 5 rises above the preset value, the PLC controller controls the heater 11 to stop operating, and then dissipates heat from the motor 5 through the circulation and heat exchange of the coolant. This setting allows the motor 5 to always operate at a suitable temperature, extending its service life, increasing work efficiency, and also heating and controlling the temperature of the raw materials, further improving the pulping efficiency.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
