Description

Technical Field

[0001] This utility model relates to the field of mixing structure technology, specifically to a mixing structure and device for producing low-carbon cementitious materials. Background Technology

[0002] Low-carbon cementitious materials are a new type of building material, mainly prepared from industrial solid waste (such as fly ash, slag, and coal gangue). Low-carbon cementitious materials have lower production energy consumption and carbon emissions, while maintaining similar strength and durability to traditional silicate cement. The preparation of low-carbon cementitious materials requires the use of mixing equipment to blend the raw materials.

[0003] Patent document CN 216935613 U discloses a cementitious material mixer, including a mixing box with a mixing chamber inside. A motor layer is located at the bottom of the mixing box, and a second rotary motor is installed within the motor layer. The second rotary motor has a drive shaft that penetrates the mixing box and extends into the mixing chamber. The conical feed inlet of this invention makes it easier for the cementitious mixture to be fed into the mixing chamber. A sealing element prevents the discharge pipe from flowing into the discharge pipe during processing. The transmission box slides more stably within the mixing chamber under the action of a sliding groove and a sliding strip. The transmission shaft drives the stirring paddle through a first and second transmission gear for mixing. After starting, the rotary motor rotates the motor housing, causing the stirring shaft and transmission box to rotate within the mixing chamber. A scraper, driven by the second rotary motor, scrapes off the cementitious mixture adhering to the inner wall of the mixing chamber, thereby improving the mixing effect.

[0004] While the cementitious material mixers disclosed in the aforementioned patent documents can achieve a homogenizing effect, they still suffer from inconvenience and incomplete cleaning of the cementitious material adhering to the inner wall of the mixing chamber. Furthermore, some cementitious materials require temperature control during mixing, which this mixer cannot achieve, thus limiting its applicability. Utility Model Content

[0005] The technical problem to be solved by this utility model is that current mixers are inconvenient to clean and cannot thoroughly clean the inside of the mixing chamber. Based on this, this utility model proposes a mixing structure and device for producing low-carbon cementitious materials. This mixing structure can thoroughly clean the inside of the mixing chamber and the stirring structure, and the mixing efficiency is also higher.

[0006] This utility model is achieved through the following technical solution:

[0007] In a first aspect, this application provides a mixing structure for producing low-carbon cementitious materials, including a support frame, a cover plate connected to the top of the support frame, a lifting structure connected to the bottom of the support frame, a mixing cylinder connected to the lifting structure, and a sealing structure connecting the cover plate and the mixing cylinder; the cover plate is provided with mutually symmetrical inclined feed ports; and a stirring structure is connected to the cover plate.

[0008] A filter screen can be connected at the inclined feed inlet to filter out some impurities in the raw materials, thereby improving the quality of the prepared gelling material.

[0009] Furthermore, the lifting structure includes a cylinder or a hydraulic rod, the telescopic end of which is connected to the bottom of the mixing cylinder.

[0010] Furthermore, the sealing structure includes an annular snap-fit ​​block disposed on the cover plate, and the mixing cylinder is provided with an annular groove that snaps into the annular snap-fit ​​block.

[0011] Furthermore, the stirring structure includes a stirring shaft connected to the cover plate, stirring blades connected to the stirring shaft, a drive motor for driving the stirring shaft to rotate connected to the top of the cover plate, and the output shaft of the drive motor connected to the stirring shaft.

[0012] Furthermore, the stirring shaft is a hollow structure with an internal cavity, and an electric heating rod is installed inside the cavity of the stirring shaft.

[0013] Furthermore, a feed pipe is connected to the inclined feed inlet, and multiple feed hoppers are connected to the feed pipe.

[0014] Furthermore, the lifting structure is connected to the bottom of the mixing cylinder via a detachable connector.

[0015] The detachable connector can be either bolted or threaded.

[0016] Furthermore, the support frame includes at least two support rods, and each support rod is connected to an electric telescopic rod at its center.

[0017] Furthermore, the bottom of the mixing cylinder is provided with an arc-shaped boss, and a discharge port is provided at the bottom edge of the arc-shaped boss, and a control valve is connected to the discharge port.

[0018] Secondly, this application provides an apparatus for producing low-carbon cementitious materials, including the above-mentioned mixing structure.

[0019] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0020] (1) By connecting the mixing cylinder to the lifting structure, the mixing cylinder can be separated from the cover plate after the materials are mixed. This not only makes it easier to remove the materials from the mixing cylinder, but also makes it easier to clean the inner wall of the mixing cylinder after the materials are removed. After the mixing cylinder is separated from the cover plate, the stirring structure can also be exposed to the outside, and the staff can thoroughly clean the residual materials on the stirring structure. The cleaning is also more convenient. At the same time, the feed inlet is set as an inclined structure, so that the materials on both sides form convection when entering the mixing cylinder. The first mixing is achieved during the convection process, and then the stirring structure is used to stir and mix it in the subsequent process. This not only improves the mixing effect, but also shortens the mixing time and improves the production efficiency.

[0021] (2) By connecting an electric heating rod to the stirring shaft, the electrolytic heating rod can be turned on when the material needs to be heated, thereby raising the temperature inside the mixing cylinder, making it suitable for mixing materials that need to be heated, expanding the application range of the mixing structure and enhancing its functionality.

[0022] (3) The mixing cylinder and the lifting structure of this utility model are connected by a detachable connector, which can realize the replacement of the mixing cylinder. That is, the mixing cylinder with the same diameter but higher or lower height can be replaced according to actual needs, so that the mixing structure can install mixing cylinders of various sizes. Since the diameter is the same, the replaced mixing cylinder can still be sealed with the cover plate.

[0023] (4) By installing an electric telescopic rod in the middle of the support rod, the electric telescopic rod and the lifting structure can be opened at the same time when it is necessary to separate the mixing cylinder from the cover plate. During normal use, the electric telescopic rod is shortened, which can reduce the space occupied by the entire mixing structure.

[0024] (5) By setting an arc-shaped protrusion at the bottom of the mixing cylinder and setting a discharge port, the material can be discharged from the bottom of the mixing cylinder. Compared with discharging from the top of the mixing cylinder, discharging from the bottom makes it easier for the workers.

[0025] (6) This application connects a feed pipe to the feed inlet and connects multiple feed hoppers to the feed pipe, so that different raw materials can be put into different feed hoppers, achieving the effect of feeding at multiple inlets at the same time, shortening the feeding time, and further improving production efficiency.

[0041] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a joint, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Example 1

[0043] like Figures 1-3 As shown, this embodiment provides a mixing structure for producing low-carbon cementitious materials, including a support frame 01, a cover plate 05 connected to the top of the support frame 01, a lifting structure 10 connected to the bottom of the support frame 01, a mixing cylinder 02 connected to the lifting structure 10, and a sealing structure connecting the cover plate 05 and the mixing cylinder 02; the cover plate 05 is provided with mutually symmetrical inclined feed inlets 07; and a stirring structure is connected to the cover plate 05.

[0044] Specifically, a filter screen 12 is connected at the inclined feed inlet 07. By connecting the filter screen 12, some impurities in the raw materials can be filtered out to improve the quality of the prepared low-carbon cementitious material.

[0045] Specifically, the lifting structure 10 is a cylinder, and the telescopic end of the cylinder is connected to the bottom of the mixing cylinder 02. The cylinder drives the mixing cylinder 02 to move up and down.

[0046] Specifically, the sealing structure includes an annular snap-fit ​​block 04 disposed on the cover plate 05, and an annular groove 03 disposed on the mixing cylinder 02 to engage with the annular snap-fit ​​block 04. During the upward movement of the mixing cylinder 02 driven by the cylinder, as the mixing cylinder 02 approaches the cover plate 05, the annular snap-fit ​​block 04 on the cover plate 05 engages into the annular groove 03, thereby achieving a sealed connection between the cover plate 05 and the mixing cylinder 02.

[0047] Specifically, the mixing structure includes a mixing shaft 09 connected to a cover plate 05, with mixing blades 08 connected to the mixing shaft 09. A drive motor 06, which drives the mixing shaft 09 to rotate, is connected to the top of the cover plate 05, and the output shaft of the drive motor 06 is connected to the mixing shaft 09. Each mixing blade 08 includes three blades, one of which is installed horizontally, and one of the other two is inclined upwards and one downwards. This structure of the mixing blades 08 can achieve multi-directional mixing, further improving the uniformity of the mixed material and also further improving the mixing efficiency.

[0048] Specifically, the stirring shaft 09 is a hollow structure with an internal cavity, and an electric heating rod 11 is installed inside the cavity of the stirring shaft 09. The cover plate 05 has heat dissipation holes. A temperature sensor can also be connected inside the mixing cylinder 02, and a temperature display can be connected outside the mixing cylinder 02. The temperature sensor detects the internal temperature of the mixing cylinder 02, and the temperature display shows the internal temperature value. Operators only need to observe the temperature value on the temperature display to understand the internal temperature of the mixing cylinder 02 at any time, facilitating temperature control.

[0049] When using this mixing structure to mix low-carbon gel materials, the mixing cylinder 02 is first moved upward by the cylinder to seal the mixing cylinder 02 with the cover plate 05. Then, the material is put in from the feed inlet and slides into the mixing cylinder 02 from the inclined feed inlet. Then, the drive motor 06 is started, which makes the stirring rotate, and then the stirring blades 08 on the stirring shaft 09 rotate, so as to achieve the effect of stirring and mixing the material in the mixing cylinder 02. After material processing is complete, the mixing cylinder 02 is driven downward by a cylinder, causing it to detach from the cover plate 05. At this point, the processed material can be removed from the mixing cylinder 02. If the mixing structure is to be used to mix other materials, it needs to be cleaned. The operator can directly clean the inside of the mixing cylinder 02, providing ample operating space and high cleaning efficiency. Furthermore, the mixing structure typically retains a significant amount of material, and traditional mixing structures are difficult to clean. However, in this technical solution, the mixing structure is exposed after the mixing cylinder 02 detaches from the cover plate 05, allowing for thorough cleaning. Additionally, the feed inlet is designed with an inclined structure, causing convection as the material enters the mixing cylinder 02. This convection process achieves the initial mixing, followed by further mixing using the mixing structure. This not only improves the mixing effect but also shortens the mixing time, increasing production efficiency.

[0050] Example 2

[0051] like Figure 4As shown, based on Example 1, this example provides a mixed structure for producing low-carbon cementitious materials. The difference from Example 1 is that a feed pipe 13 is connected to the inclined feed inlet 07 in this example, and multiple feed hoppers 14 are connected to the feed pipe 13. Other structural features are the same as in Example 1.

[0052] Compared with Example 1, the advantage of this example is that some gelling materials require a variety of different raw materials in production. In this example, a feed pipe 13 is connected to the feed inlet, and multiple feed hoppers 14 are connected to the feed pipe 13. This allows different raw materials to be put into different feed hoppers 14, achieving the effect of simultaneous feeding from multiple inlets, shortening the feeding time, and further improving production efficiency.

[0053] Example 3

[0054] like Figure 5 and Figure 6 As shown, based on Embodiment 2, this embodiment provides a mixing structure for producing low-carbon cementitious materials. The difference from Embodiment 2 is that the cylinder extension end in this embodiment is connected to the bottom of the mixing cylinder 02 via a detachable connector. Other structures are the same as in Embodiment 2.

[0055] Specifically, the detachable connector includes a mounting block 15 connected to the bottom of the mixing cylinder 02, a screw section 16 connected to the telescopic end of the cylinder, a threaded groove on the mounting block 15, and a threaded connection between the screw section 16 and the screw groove.

[0056] Compared with Example 2, the advantage of this example is that the mixing cylinder 02 and the cylinder are connected by a detachable connector, which allows the mixing cylinder 02 to be replaced. That is, the mixing cylinder 02 with the same diameter but higher or lower height can be replaced according to actual needs, so that the mixing structure can install mixing cylinders 02 of various sizes. Since the diameter is the same, the replaced mixing cylinder 02 can still be sealed with the cover plate 05.

[0057] Example 4

[0058] like Figure 7 As shown, based on Embodiment 3, this embodiment provides a mixed structure for producing low-carbon cementitious materials. Unlike Embodiment 3, the detachable connector in this embodiment includes a mounting block 15 connected to the bottom of the mixing cylinder 02. The mounting block 15 is provided with bolt holes and mounting grooves. The telescopic end of the cylinder is connected to a fixing section, which is also provided with bolt holes. During installation, the fixing section is inserted into the mounting groove, and then the locking bolts 17 are installed in the bolt holes to connect and fix the cylinder to the mixing cylinder 02.

[0059] Example 5

[0060] like Figure 8As shown, based on Example 4, this example provides a hybrid structure for producing low-carbon cementitious materials. Unlike Example 4, the support frame 01 in this example includes two support rods, and each support rod 01 has an electrically operated telescopic rod 18 connected to its middle section. Other structural features are the same as in Example 4.

[0061] Compared with Embodiment 4, the advantage of this embodiment is that by installing the electric telescopic rod 18 in the middle of the support rod, the electric telescopic rod 18 and the lifting structure 10 can be opened simultaneously when it is necessary to separate the mixing cylinder 02 from the cover plate 05. During normal use, the electric telescopic rod 18 is shortened, which can reduce the space occupied by the entire mixing structure.

[0062] Example 6

[0063] like Figure 9 As shown, based on Example 5, this example provides a mixing structure for producing low-carbon cementitious materials. Unlike Example 5, the mixing cylinder 02 in this example has an arc-shaped boss 19 at its bottom, and a discharge port 20 is located at the bottom edge of the arc-shaped boss 19. A control valve is connected to the discharge port 20. Other structural features are the same as in Example 5.

[0064] Compared with embodiment 5, the advantage of this embodiment is that by setting an arc-shaped protrusion 19 at the bottom of the mixing cylinder 02 and setting a discharge port 20, the material can be discharged from the bottom of the mixing cylinder 02. Compared with discharging from the top of the mixing cylinder 02, discharging from the bottom makes it easier for the workers.

[0065] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
