However, these terms are used herein merely for illustrative purposes and are determined based on the exemplary orientations shown in the accompanying drawings. Therefore, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0035] The following describes a raw material mixing device of the present invention in further detail with reference to the accompanying drawings.

[0036] Example 1

[0037] Depend on Figures 1 to 3 As shown,

[0038] A raw material mixing device includes a tank 7 with an open top and a stirring group. The stirring group includes a stirrer 1 and a motor 6 connected to each other. The motor 6 is located outside the tank 7, and the stirrer 1 is horizontally arranged inside the tank 7.

[0039] The bottom of the tank body 7 is connected to a discharge pipe 10, and the discharge pipe 10 is equipped with a discharge valve 11.

[0040] To prevent dust from flying during the mixing process, the upper opening of the tank body 7 is detachably connected to a top cover 8, and the top cover 8 is equipped with a feed pipe 9.

[0041] Example 2

[0042] Depend on Figures 4 to 8 As shown, based on the above embodiment 1, the difference lies in that the stirrer 1 includes an intermediate shaft 101 and a rotating plate 103. Several support rods 102 are symmetrically arranged at both ends of the intermediate shaft 101, and the rotating plate 103 is arranged between the support rods 102 arranged on both sides. Several support rods 102 on the same side are arranged in a ring array around the axis of the intermediate shaft 101.

[0043] The upper end of the stirrer 1 is provided with a scraper 2, and the top of the scraper 2 is provided with a fixing frame 201. The scraper 2 is fixedly connected to the tank body 7 of the mixing tank through the fixing frame 201. The fixing frame 201 is located above the stirrer 1, so it will not interfere with the rotation of the stirrer 1.

[0044] In order to arrange the compartments, the tank 7 includes a cuboid cleaning chamber 702 and a cylindrical stirring chamber 701 that are connected vertically. The stirrer 1 is coaxially arranged inside the stirring chamber 701, and the scraper 2 is fixed inside the cleaning chamber 702.

[0045] When the rotating plate 103 of the agitator 1 is rotated to the top, it is arranged horizontally, and the bottom scraping surface of the scraper 2 abuts against the top surface of the rotating plate 103 arranged horizontally at the top.

[0046] The agitator 1 is horizontal, that is, the intermediate shaft 101 is arranged horizontally. The material is stirred by the rotating plate 103. When the rotating plate 103 rotates to the top, it is arranged horizontally. The material at the bottom of the rotating plate 103 falls off under the action of gravity, and the material above it is scraped off by the scraper 2 during the rotation of the rotating plate 103.

[0047] The scraper 2 is provided with a water pipe 3 arranged parallel to it, and a number of spray holes are spaced apart on the water pipe 3. The spray holes on the water pipe 3 face the front end face of the scraper 2.

[0048] Water is added to the mixing tank through water pipe 3. Water can be added in stages. When adding water, the water jet from the nozzle is sprayed onto the front end of scraper 2 to wash away the material remaining on it, ensuring the cleaning effect of scraper 2 on rotating plate 103 in the next cycle.

[0049] An atomizing nozzle can be added to the outside of the spray hole to further optimize the cleaning effect on scraper 2.

[0050] The rotating plate 103 is rotatably connected to the end of the support rod 102. During the rotation of the stirrer 1, the rotating plate 103 rotates on its own, which improves the stirring efficiency.

[0051] The stirrer 1 has a guide plate 5 arranged coaxially on its inner side. When rotated, the lower half of the upper rotating plate 103 abuts against the guide plate 5, and gradually changes to a horizontal arrangement. The guide plate 5 is an arc-shaped plate, and its center is located on the axis of the intermediate shaft 101.

[0052] The rotating plate 103 is coaxially fixed with a rotating shaft 104 at its end. The rotating shaft 104 passes through to the outside of the support rod 102. An end plate 105 is fixed at the end of the rotating shaft 104. A spring 106 is sleeved on the rotating shaft 104. The spring 106 is located between the end plate 105 and the support rod 102.

[0053] The support rod 102 is provided with a plurality of slots 1021 arranged around the axis of the rotating shaft 104. A plug rod 1041 is protruding on the rotating shaft 104 located outside the support rod 102. The plug rod 1041 is inserted into the slot 1021. Under the push of the spring 106, the plug rod 1041 is placed outside the slot 1021.

[0054] A pressing plate 4 is provided on the rotation path of the rotating shaft 104 around the intermediate shaft 101. A mounting block 401 protrudes from the outer side of the pressing plate 4 and is inserted into a groove in the inner wall of the tank body 7. In order to achieve positioning installation, the mounting block 401 is polygonal in shape.

[0055] The extrusion plate 4 is connected to the end plate 105. The extrusion plate 4 is an arc-shaped plate, and the center of the extrusion plate 4 is located on the axis of the intermediate shaft 101. The thickness at both ends of the extrusion plate 4 is less than the thickness in the middle.

[0056] The guide plate 5 is located at the front end of the extrusion plate 4. That is, during the rotation of the agitator 1, the bottom of the rotating plate 103 first contacts the guide plate 5, and gradually changes from a vertical state to a horizontal state. When the rotating plate 103 is separated from the guide plate 5, it is already in a horizontal state, and then its corresponding end plate 105 directly contacts the extrusion plate 4.

[0057] On the horizontal rotating plate 103, the insertion rod 1041 of the rotating shaft 104 is arranged correspondingly to the slot 1021. The end of the insertion rod 1041 facing the slot 1021 is tapered, which makes it easy to insert into the slot 1021.

[0058] After the end plate 105 and the extrusion plate 4 are extruded, the end plate 105 gradually moves towards the support rod 102, and the insertion rod 1041 is inserted into the slot 1021. The rotating plate 103 cannot rotate and remains in a horizontal position, which makes it easy for the scraper 2 to clean its upper surface.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
