DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0020] Reference Figure 1-Figure 5 As shown, a spiral mixing device that is easy to clean includes a conical mixing barrel 1 with an opening on the top, a cover plate 2 arranged on the upper part of the conical mixing barrel 1 and a spiral stirring assembly 4 installed on the cover plate 2, wherein the cover plate 2 can move up and down above the conical mixing barrel 1, and an annular drain pipe 7 is arranged at the top edge of the conical mixing barrel 1, and the input end of the annular drain pipe 7 is connected to a water pump 5 through a connecting pipe 6, and a plurality of first nozzles 8 are evenly spaced and circumferentially arranged on the annular drain pipe 7.

[0021] Specifically, refer to Figure 1-Figure 5 The working principle of the spiral mixing device is that when the cover plate 2 and the conical mixing barrel 1 are in a state of being in contact with each other, the conical mixing barrel 1 is in a closed state, and the spiral stirring component 4 works to mix and stir the materials inside the conical mixing barrel 1. When cleaning the existing spiral mixing device, water is directly injected through the feed port on the cover plate 2 for cleaning. However, the injected clean water cannot contact the spiral stirring component 4, and materials will remain on the spiral stirring component 4, resulting in poor cleaning effect. Based on the deficiencies of the prior art, the utility model adds a cleaning component and enables the cover plate 2 to be separated from the conical mixing barrel 1, so that the spiral stirring component 4 can be outside the conical mixing barrel 1, which is convenient for cleaning the spiral stirring component 4. The washing assembly includes an annular drain pipe 7 arranged at the top edge of the conical mixing barrel 1, a water pump 5 connected to the input end of the annular drain pipe 7 and a first nozzle 8 on the annular drain pipe 7. During cleaning, the cover plate 2 drives the spiral stirring assembly 4 to rise, so that the spiral stirring assembly 4 rises from the inside of the conical mixing barrel 1, and the water pump 5 supplies water to the inside of the annular drain pipe 7 through the connecting pipe 6. The water flow is sprayed from the first nozzle 8 to achieve cleaning of the inner wall of the conical mixing barrel 1, wherein the spray angle of the first nozzle 8 is optimally set in the tangent direction of the conical mixing barrel 1. When the spiral stirring assembly 4 is outside, it can be cleaned through an external faucet or by the vertical drain pipe 9 and the second nozzle 10 described below.

[0022] Furthermore, the output end of the annular drain pipe 7 is also connected to a vertical drain pipe 9 extending upward from the upper surface of the conical mixing barrel 1 , and second nozzles 10 are linearly arranged at even intervals on the vertical drain pipe 9 .

[0023] Among them, Figure 3 As shown, the cleaning component also includes a vertical drain pipe 9 and a second nozzle 10. When the spiral stirring component 4 is cleaned, the second nozzle 10 sprays water to control the spiral stirring component 4 to be in a state of revolution and rotation, so that the water sprayed by the second nozzle 10 can impact the spiral stirring component 4 to clean the spiral stirring component 4. By separating the spiral stirring component 4 from the conical mixing barrel 1, it is convenient to clean the spiral stirring component 4. At the same time, adding the vertical drain pipe 9 and the second nozzle 10 can facilitate automatic flushing.

[0024] Furthermore, a telescopic rod 3 is fixedly connected to the edge of the lower surface of the cover plate 2 , and the cover plate 2 is displaced upward or downward on the conical mixing barrel 1 by the extension or contraction of the telescopic rod 3 .

[0025] Among them, Figure 1 and Figure 2As shown, by setting the telescopic rod 3, the cover plate 2 can be driven to move up and down. When the telescopic rod 3 corresponds to the maximum stroke, the cover plate 2 is lifted to the highest point. At this time, the spiral stirring assembly 4 is completely separated from the conical mixing barrel 1, which is convenient for cleaning. When the telescopic rod 3 drives the cover plate 2 to fit with the conical mixing barrel 1, the conical mixing barrel 1 is closed, which is convenient for stirring and mixing the materials inside the conical mixing barrel 1.

[0026] Furthermore, a cylindrical protective cylinder 11 is fixedly connected to the edge of the upper surface of the conical mixing cylinder 1 , and the second nozzle 10 penetrates the side wall of the cylindrical protective cylinder 11 and extends to the inside of the cylindrical protective cylinder 11 .

[0027] Among them, Figure 4 and Figure 5 As shown, the cylindrical protective tube 11 can prevent the water sprayed by the second nozzle 10 from splashing to the outside, thereby achieving a protective effect.

[0028] Furthermore, an opening and closing door 12 is provided on the cylindrical protective tube 11 .

[0029] Among them, Figure 4 and Figure 5 As shown, the opening and closing door 12 is arranged on the cylindrical protective tube 11, so as to prevent the cylindrical protective tube 11 from obstructing the workers during the injection process.

[0030] Furthermore, the height of the cylindrical protective tube 11 is equal to the maximum telescopic displacement height of the telescopic rod 3 .

[0031] Among them, Figure 1-Figure 4 As shown, the height of the cylindrical protective tube 11 is equal to the maximum telescopic displacement height of the telescopic rod 3 , which can prevent the cover plate 2 from leaving the range of the cylindrical protective tube 11 .

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
