They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0034] refer to Figure 1-8 An embodiment of this utility model shows a mixing and proportioning equipment for a new type of environmentally friendly building material, lightweight bricks, including a mixing unit 1 and multiple feeding units 2.
[0035] The mixing unit 1 includes a mixing tank 11 with an opening 111 at the top. A rotating shaft 12 is installed inside the mixing tank 11 and is connected to a first drive source 13. Multiple stirring blades 121 are mounted on the rotating shaft 12. Multiple feeding units 2 are arranged on one side of the mixing tank 11. Each feeding unit 2 includes a frame 21 with a feeding box 22. An inclined feeding channel 221 is formed inside the feeding box 22, and a screw conveyor shaft 23 is installed inside the feeding channel 221. A second drive source 24 is located at the higher end of the feeding channel 221 and is connected to the screw conveyor shaft 23. An outlet 222 is located at the lower end of the feeding channel 221, above the mixing tank 11. A feeding hopper 25 is located at the top of the feeding box 22 and is connected to the feeding channel 221. The second drive source 24 is a motor.
[0036] Specifically, different raw materials are fed into different feeding hoppers 25. The raw materials enter the feeding channel 221 and are driven by the screw conveyor shaft 23 to the discharge port 222. During this process, the agglomerated raw materials will be broken by the screw conveyor shaft 23, which can greatly reduce the agglomeration in the raw materials. After that, the raw materials are discharged from the discharge port 222 and enter from the opening 111 at the top of the mixing tank 11. Multiple raw materials are gathered in the mixing tank 11 and mixed by the stirring blades 121 on the rotating shaft 12.
[0037] Preferably, the discharge port 222 of the feeding channel 221 is equipped with a valve (not shown) for controlling its opening and closing. This valve can be manually or electrically controlled. Thus, when raw materials are fed into the feeding hopper 25, the valve can be closed first, allowing the raw materials to be agitated by the screw conveyor shaft 23 within the feeding channel 221 for a longer period. Raw materials can be fed into the feeding hopper 25 manually or mechanically. If manually fed, workers feed the raw materials sequentially; during the feeding process, the first batch of raw materials is thoroughly agitated by the screw conveyor shaft 23, breaking up any agglomerates. Since the process of breaking up agglomerates occurs simultaneously with the feeding process, it does not increase the production time required.
[0038] Thus, the mixing and proportioning equipment for the new environmentally friendly building material lightweight brick in this embodiment can independently feed multiple raw materials by setting multiple feeding units 2, thereby improving the accuracy of the proportioning. The bolt conveying shaft in the feeding unit 2 has a certain crushing effect on the agglomerated raw materials, which can reduce the agglomeration of raw materials, so that the subsequent mixing is easier and more thorough, which can reduce the mixing time of the subsequent mixing unit 1 and improve the mixing efficiency.
[0039] In some embodiments, to improve security, such as Figure 1 and Figure 4 As shown, a grid cover plate 14 is provided on the opening 111 at the top of the mixing tank 11. One side of the grid cover plate 14 is hinged to the mixing tank 11 to achieve flipping. A bracket 15 is provided on one side of the mixing tank 11 to support the grid cover plate 14, so that it is easier for workers to close the grid cover plate 14.
[0040] The grating cover 14 can seal the opening 111 at the top of the mixing tank 11, preventing workers from falling and avoiding industrial accidents. In a preferred embodiment, a sensor can be installed on the mixing tank 11 to detect whether the grating cover 14 is closed. If the sensor detects that the grating cover 14 is open, the first drive source 13 will not be activated. In other words, when the grating cover 14 is open, the rotating shaft 12 inside the mixing tank 11 will not rotate, ensuring the safety of workers even if they fall into the mixing tank 11.
[0041] In some embodiments, the first drive source 13 includes a motor, and the first drive source 13 and the rotating shaft 12 are connected by a belt drive. In other embodiments, chain drive or gear drive are not excluded.
[0042] In some embodiments, such as Figure 6 As shown, the mixing tank 11 is provided with an output port 112 at both the end and the bottom, and a closing mechanism 16 is provided on the output port 112.
[0043] Depending on the spatial constraints of the actual application site, the material can be discharged at the end or bottom of the mixing tank 11.
[0044] Specifically, such as Figure 7 and Figure 8 As shown, the sealing mechanism 16 includes a first mounting plate 161, a second mounting plate 162, rubber septa 163, and an insert plate 164. The first mounting plate 161, rubber septa 163, and second mounting plate 162 are sequentially arranged outside the output port 112. Both the first mounting plate 161 and the second mounting plate 162 are provided with through holes corresponding to the output port 112. A gap 165 is provided between the first mounting plate 161 and the second mounting plate 162 for the insert plate 164 to be inserted. There are three rubber septa 163, which are arranged on the outside of the output port 112. The insert plate 164 is inserted between the three rubber septa 163. When the insert plate 164 is pulled out, the insert plate 164 and the three rubber septa 163 surround the output port 112. In other words, when the insert plate 164 is inserted into the gap 165, the partition closes the output port 112, allowing multiple raw materials to be mixed in the mixing tank 11. After the mixing is completed, the insert plate 164 can be pulled out, opening the output port 112 for easy discharge. The insert plate 164 is not completely detached; part of its edge remains in the gap 165, preventing the mixed raw materials from leaving the gap 165 between the first mounting plate 161 and the second mounting plate 162.
[0045] In some embodiments, to facilitate connection of the output port 112 to other devices or pipes, such as Figure 7 and Figure 8 As shown, a circular tube structure 1621 is provided on the outer side of the second mounting plate 162. The circular tube structure 1621 can be used to connect with other equipment or pipes.
[0046] Specifically, in the above scheme, the mixing tank 11, the first mounting plate 161, the rubber septum 163, and the second mounting plate 162 are connected by bolt assemblies.
[0047] In summary, this application provides a new type of mixing and proportioning equipment for lightweight bricks, an environmentally friendly building material. By setting up multiple feeding units 2, various raw materials can be fed independently, improving the accuracy of the proportioning. The bolt conveying shaft in the feeding unit 2 has a certain crushing effect on the agglomerated raw materials, which can reduce the agglomeration of raw materials, so that the subsequent mixing is easier and more thorough, reducing the mixing time of the subsequent mixing unit 1 and improving the mixing efficiency.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
