Description

Technical Field

[0001] This application relates to the field of mortar production equipment, and more specifically, to a mixing device and mortar production equipment. Background Technology

[0002] Mortar is made by mixing inorganic cementing materials, fine aggregates, and water in a specific ratio. It is also called mortar. Used in masonry and plastering projects, it can be divided into masonry mortar and plastering mortar. The former is used for the construction of bricks, stones, blocks, etc., and for the installation of components; the latter is used for plastering the surfaces of walls, floors, roofs, and beam and column structures to achieve protective and decorative requirements. Other common mortar materials are made by mixing gypsum, lime paste, or clay with fibrous reinforcing materials and water to form a paste-like substance, called mortar, paste, mud, or putty. Commonly used types include hemp fiber mortar (lime paste mixed with hemp fibers), paper fiber mortar (lime paste mixed with paper fibers), gypsum mortar (lime paste mixed with calcined gypsum and paper fibers or glass fibers), and mortar-mixed mud (clay mixed with a small amount of lime and wheat straw or rice straw).

[0003] Based on their constituent materials, ordinary mortar can be further divided into: ① Lime mortar. Made from lime paste, sand, and water in a specific ratio, it is generally used for masonry and plastering layers where strength requirements are not high and moisture is not a concern; ② Cement mortar. Made from cement, sand, and water in a specific ratio, it is generally used for masonry, walls, or floors in damp environments or underwater; ③ Mixed mortar. Made by adding appropriate admixtures such as fly ash and diatomaceous earth to cement or lime mortar to save on cement or lime usage and improve the workability of the mortar. Commonly used mixed mortars include cement-lime mortar, cement-clay mortar, and lime-clay mortar.

[0004] Freshly mixed ordinary mortar should have good workability, while hardened mortar should possess the required strength and bonding force. The workability of mortar is related to its fluidity and water retention, and is generally determined based on construction experience or through testing. The compressive strength of mortar is expressed by its grade; commonly used ordinary mortar grades include 4, 10, 25, 50, and 100. Mortar grades of 100 and above are only required for masonry works with high strength requirements and critical applications. The bonding force of mortar increases with its grade and is also related to the surface condition of the masonry, its cleanliness, moisture level, and construction and curing conditions. Therefore, bricks are generally moistened before laying to enhance the bond between the brick and the mortar, ensuring the quality of the masonry work.

[0005] The difference between building mortar and concrete is that building mortar does not contain coarse aggregate; it is made by mixing cementitious materials, fine aggregate, and water in a certain proportion. According to its use, it is divided into masonry mortar and plastering mortar; according to the different materials used, it is divided into cement mortar, lime mortar, gypsum mortar, and cement-lime mixed mortar, etc. The rational use of mortar plays an important role in saving cementitious materials, facilitating construction, and improving project quality.

[0006] Mortar needs to be stirred during preparation. For example, a mortar storage tank disclosed in Chinese application No. 202221458740.6 can mix the mortar in the mixing tank evenly, thereby reducing the possibility of mortar segregation and improving the quality of mortar stored in the tank. However, all the stirring rods are in the same direction, which leads to poor mixing effect and makes it difficult to clean all the internal structures of the mixing chamber during subsequent material discharge and cleaning. Summary of the Invention

[0007] To overcome the shortcomings of the existing system, this application provides a mixing device and mortar production equipment, which can solve the problem that all the mixing rods have the same mixing direction, which leads to poor mixing effect and makes it difficult to clean all the internal structures of the mixing chamber during subsequent material feeding and cleaning.

Detailed Implementation

[0026] The technical solution in this application embodiment is to solve the problem that all the stirring rods have the same stirring direction, which leads to poor stirring effect and makes it difficult to clean all the internal structures of the stirring chamber 110 during subsequent material feeding and cleaning. The overall idea is as follows:

[0027] Please see Figures 1-5 A mixing device and mortar production equipment, comprising a storage component 10 and a mixing component 20.

[0028] Please see Figure 1 and Figure 3 The storage component 10 includes a mixing chamber 110, and a discharge port 140 is provided at the bottom of the mixing chamber 110; wherein, the mortar is stored inside the mixing chamber 110 and then discharged through the discharge port 140.

[0029] The bottom of the mixing chamber 110 is supported by a support frame 120. The top of the mixing chamber 110 is equipped with a water inlet pipe 130.

[0030] Please see Figure 1 and Figure 2 The mixing assembly 20 includes a motor 210, which is installed in the mixing chamber 110. A cylindrical mixing shaft 220 is fixedly connected to the output end of the motor 210. The cylindrical mixing shaft 220 extends into the interior of the mixing chamber 110. Several extension columns 230 are arranged in a circular array on the outer side of the cylindrical mixing shaft 220. Each extension column 230 is fixedly connected to a connecting rod 240, and each connecting rod 240 extends at a different angle. A mixing scraper 250 is installed on each connecting rod 240. During mixing, the motor 210 is started, causing the cylindrical mixing shaft 220 to rotate, which in turn drives each extension column 230 to rotate. The rotation of the extension columns 230 drives the connecting rods 240 to rotate, which in turn causes each mixing scraper 250 to rotate, thereby achieving the mixing and blending of the mortar raw materials inside the mixing chamber 110. By using different angles for each connecting rod 240, each mixing scraper 250 can rotate at different angles, achieving multi-angle and multi-directional rotation. This results in better mixing efficiency when mixing mortar raw materials, and also makes subsequent material discharge and cleaning smoother and cleaner.

[0031] The stirring scraper 250 is in contact with the bottom of the stirring chamber 110, the stirring scraper 250 is in contact with the inner wall of the stirring chamber 110, the stirring scraper 250 is in contact with the outer wall of the cylindrical stirring shaft 220, and the stirring scraper 250 is suspended in the air. During rotation, the mixing scraper 250, which contacts the inner and bottom walls of the mixing chamber 110, scrapes the inside of the mixing chamber 110 to prevent dry powder from adhering to the inner and bottom walls during mixing. It also makes it easier to clean the mixing chamber 110 during cleaning. Furthermore, the mixing scraper 250, which contacts the bottom of the mixing chamber 110, can also rotate during material feeding to push the mortar to the discharge port 140, making the mortar feeding smoother. The mixing scraper 250, which contacts the cylindrical mixing shaft 220, scrapes the outer wall of the cylindrical mixing shaft 220 to prevent dry powder from adhering to the outer wall of the cylindrical mixing shaft 220 during mixing. It also makes it easier to clean the outer wall of the cylindrical mixing shaft 220 during cleaning.

[0032] Please see Figure 1 , Figure 4 and Figure 5 The mixing device also includes a feeding assembly 30, which is located at the top of the mixing chamber 110 and communicates with it. The feeding assembly 30 includes a feeding chamber 310, which communicates with the top of the mixing chamber 110. Inside the feeding chamber 310 are two sets of downwardly inclined baffles 320. One set of baffles 320 is inclined downwards from left to right, and the other set is inclined downwards from right to left. The two sets of baffles 320 are symmetrically arranged to form a discharge channel. An elastic support member 330 is provided between each baffle 320. The elastic support member 330 includes a support sleeve 331. The bottom end of the support sleeve 331 is fixedly connected to the upper surface of one baffle 320. A support spring 333 is provided inside the support sleeve 331. A support column 332 is provided at the other end of the support spring 333, and the other end of the support column 332 is fixedly connected to the lower surface of the other baffle 320. The staggered and symmetrical arrangement of the baffle plates 320 can buffer the force of the mortar raw materials during feeding, thereby improving the service life of the mixing chamber 110, the columnar mixing shaft 220 and the internal structure.

[0033] Please see Figures 1-5 The technical solution adopted by the embodiments of this application to solve its technical problem is: mortar production equipment, including a mixing device.

[0034] When this application is used:

[0035] During mixing, the motor 210 is started, causing the cylindrical mixing shaft 220 to rotate, which in turn drives each extension column 230 to rotate. The rotation of the extension columns 230 drives the connecting rod 240 to rotate, which in turn drives each mixing scraper 250 to rotate, thereby achieving mixing of the mortar raw materials inside the mixing chamber 110. Because each connecting rod 240 has a different angle, each mixing scraper 250 rotates at a different angle, achieving multi-angle and multi-directional rotation. This results in better mixing efficiency when mixing the mortar raw materials, and also makes subsequent material discharge and cleaning smoother and cleaner.

[0036] In summary, this application achieves different angles for each connecting rod 240, resulting in different angles for each mixing scraper 250 during rotation. This enables multi-angle and multi-directional rotation, leading to better mixing efficiency when mixing mortar raw materials and smoother and cleaner subsequent material discharge and cleaning.

[0037] It should be noted that the specific model and specifications of motor 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0038] The power supply and principle of motor 210 are clear to those skilled in the art and will not be described in detail here.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
