[0023] This utility model provides a high-efficiency mixing device, including a mixing drum 101, a motor 102, a rotating shaft 103, a stirrer 104, and a mounting mechanism. The mounting mechanism includes two scraper blades 105, a connecting rod 106, multiple heating wires 107, two nozzles 108, and two nozzle connectors 109. The mounting mechanism also includes a mounting shell 110, a thermometer 111, and a heat insulation component. The heat insulation component includes a heat insulation plate 112 and a heating tube 113. The above structure solves the problems of inconvenient cleaning, plastic easily adhering to the inner wall of the mixing drum 101 and the stirrer 104, which is difficult to remove after hardening, thus shortening the service life of the equipment and causing material waste.
[0024] In a specific embodiment, the mixing drum 101 is provided with a feed inlet 114 at the top and a discharge outlet 115 at the bottom. The motor 102 is installed at the top of the mixing drum 101, and the output end of the motor 102 passes through the mixing drum 101. The rotating shaft 103 is fixedly connected to the output end of the motor 102 and is located inside the mixing drum 101. The stirrer 104 is fixedly connected to the rotating shaft 103 and is located on the outer wall of the rotating shaft 103. In use, the raw materials are added into the mixing drum 101 through the feed inlet 114, driving the motor 102 to operate. The motor 102 drives the rotating shaft 103 to rotate, and the stirrer 104 mixes the raw materials in the mixing drum 101.
[0025] Two scraper blades 105 are disposed opposite each other inside the mixing cylinder 101, and the scraper blades 105 are in contact with the inner wall of the mixing cylinder 101. A connecting rod 106 is fixedly connected between the two scraper blades 105 and the rotating shaft 103. A plurality of heating wires 107 are respectively disposed inside the stirrer 104 and the two scraper blades 105. Two nozzles 108 are respectively installed inside the mixing cylinder 101. One end of each of the two nozzle connectors 109 is connected to the two nozzles 108, and the other end of each nozzle connector 109 passes through the mixing cylinder 101 and extends out of the mixing cylinder 101. The motor 102 operates, the rotating shaft 103 rotates, and the scraper blades 105... The raw materials adhering to the inner wall of the mixing drum 101 are scraped off to ensure more thorough mixing. During discharge, the raw materials adhering to the inner wall of the mixing drum 101 can also be scraped off to reduce waste. When cleaning the mixing drum 101, it is connected to an external hot water pipe through the nozzle connector 109. The nozzle 108 sprays water to clean the scraper plate 105 and the agitator 104. Simultaneously, the heating wire 107 inside the scraper plate 105 and the agitator 104 further prevents the raw materials from solidifying. This solves the problems of inconvenient cleaning, plastic easily adhering to the inner wall of the mixing drum 101 and the agitator 104, hardening and being difficult to remove, thus shortening the equipment's lifespan and causing material waste.
[0026] The mounting shell 110 is installed on the outer wall of the mixing cylinder 101, the thermometer 111 is installed on the top of the mixing cylinder 101 and penetrates through the mixing cylinder 101, and the heat insulation component is disposed inside the mounting shell 110. The mounting shell 110 is used to install the thermometer 111 and the heat insulation component. The thermometer 111 is used to detect the temperature inside the mixing cylinder 101 to avoid the temperature being too low, which would cause the raw materials inside the mixing cylinder 101 to solidify and affect the mixing efficiency. The heat insulation component is used to heat and insulate the entire mixing cylinder 101.
[0027] The insulation plate 112 is fixedly connected to the mounting shell 110 and is located on the inner side wall of the mounting shell 110. The heating tube 113 is sleeved on the outer side wall of the mixing cylinder 101. The insulation plate 112 is used to keep the mixing cylinder 101 warm, and the heating tube 113 is used to heat the entire mixing cylinder 101 to avoid temperature filtration and solidification inside the mixing cylinder 101.
[0028] When using the high-efficiency mixing device of this utility model, the raw materials are added into the mixing drum 101 through the feed port 114, the motor 102 is driven to operate, the motor 102 drives the rotating shaft 103 to rotate, the stirrer 104 mixes the raw materials in the mixing drum 101, and the scraper 105 scrapes off the raw materials adhering to the inner wall of the mixing drum 101, so that the raw materials are mixed more thoroughly. During discharge, the raw materials adhering to the inner wall of the mixing drum 101 can also be scraped off to reduce the amount of raw materials. To avoid waste, when cleaning the mixing drum 101, the nozzle is connected to an external hot water pipe through the nozzle connector 109. The nozzle 108 sprays water to clean the scraper 105 and the agitator 104. At the same time, the heating wire 107 inside the scraper 105 and the agitator 104 can further prevent the raw materials from solidifying. This solves the problems of inconvenient cleaning, plastic easily adhering to the inner wall of the mixing drum 101 and the agitator 104, which is difficult to remove after hardening, thus shortening the service life of the equipment and causing waste of raw materials.
