Description

Technical Field

[0001] This utility model relates to the field of quartz stone raw material mixing technology, specifically to a quartz stone production raw material mixing device. Background Technology

[0002] Quartz stone is a new type of artificial stone made of over 90% quartz crystals, resin, and other trace elements. It is produced by pressing large-format slabs under specific physical and chemical conditions using specialized machinery. Due to its unique properties and beautiful appearance, quartz stone is widely used in architectural decoration and home renovation. Quartz stone primarily uses quartz sand / powder as aggregate, accounting for over 90% of the raw materials. Quartz sand is produced by crushing quartz stone and its main component is silicon dioxide. Resin is used as a binder, accounting for approximately 8% to 15% of the formula by mass. The resin imparts toughness and adhesion to quartz stone, and its content directly affects the quality of the stone. In addition to quartz sand / powder, fillers such as foundry sand, crushed glass, seashells, and sea sand are also included. These materials can adjust the physical properties and appearance of quartz stone.

[0003] Currently, the production of quartz stone requires mixing quartz sand / powder, fillers, and auxiliary materials before transporting them to the synthesis station. This separation of mixing and transportation into two separate processes is not conducive to shortening production time or improving production efficiency. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A quartz stone production raw material mixing device includes a conveying pipe with multiple equally spaced return ports at the bottom of the conveying pipe. Each return port has a material distribution port at the bottom of the conveying pipe behind it. A mixing pipe is fixed to the bottom of the conveying pipe at the return port. The mixing pipe is connected to the inside of the conveying pipe through the return port. A through-hole is opened on the bottom side of the mixing pipe facing the material distribution port. A guide pipe is fixed between the through-hole and the material distribution port. The conveying pipe, the guide pipe, and the mixing pipe are connected.

[0006] Furthermore, a concentric conveying shaft is installed inside the conveying pipe, and a spiral conveying blade is fixed on the conveying shaft. Shaft seats are installed inside the conveying pipe at both ends of the conveying shaft, and the two ends of the conveying shaft are installed with the corresponding shaft seats. A conveying motor is installed on the outer side of the rear end of the conveying pipe, and the output end of the conveying motor is fixedly connected to the corresponding conveying shaft. Compared to belt conveyors, the spiral conveying blades not only convey the raw materials but also have a certain mixing effect, providing more mixing time for the raw materials to achieve a better mixing effect.

[0007] Furthermore, a fixed base is fixed to the bottom of the stirring tube, and a support column for ground support is fixed to the bottom of the fixed base. The support column distributes the weight of the stirring tube to ensure that the stirring tube is fixed in a stable and reliable position.

[0008] Furthermore, a concentric stirring shaft is installed inside the stirring tube, and a spiral stirring blade is fixed on the stirring shaft. The bottom of the stirring shaft is installed with a corresponding fixed seat, and a stirring motor is installed below the fixed seat. The output end of the stirring motor is fixedly connected to the stirring shaft at the corresponding position. Since the stirring tube is installed at the bottom of the conveying pipe, the raw material in the stirring tube needs to be returned to the conveying pipe. Therefore, the spiral stirring blade can be used to stir and push the raw material upwards at the same time, thereby supplementing the raw material at the guide pipe position. This forms a cycle in which the raw material enters the stirring tube through the guide pipe, is stirred and pushed upwards by the spiral stirring blade, and then re-enters the conveying pipe.

[0009] Furthermore, multiple equally spaced fixed platforms are fixed to the bottom of the conveying pipe, and a ground-supporting frame is fixed to the bottom of each fixed platform. A fixing frame is fixed to the bottom of the fixed base corresponding to the position of the stirring motor, and the stirring motor is installed and fixed to the fixing frame. The stirring pipe is perpendicular to the conveying pipe and located below the conveying pipe, so a support frame is set to support the conveying pipe off the ground, meeting the installation space requirements of the stirring pipe.

[0010] Furthermore, the inner diameters of the conveying pipe, the stirring pipe, and the guide pipe decrease sequentially. The use of multiple stirring pipes and guide pipes increases the number of times the raw material enters the stirring pipe, allowing for sufficient mixing to achieve the desired effect through multiple stirring processes.

[0011] Furthermore, the conveying pipe has an inlet and an outlet located above the rear side and below the front side, respectively, near both ends of the conveying shaft. This facilitates the pouring of raw materials to be stirred into the conveying pipe and the pouring out of the stirred materials for centralized collection and use.

[0012] Furthermore, a feed hopper and a discharge bin are fixed on the conveying pipe at the corresponding inlet and outlet positions, respectively, with the bottom of the discharge bin inclined radially towards the conveying pipe. This inclined arrangement allows the raw material to flow out at an angle, thus enabling it to flow a greater distance. When using a container for centralized collection, the container opening can be better opened, facilitating the retrieval of the collected raw material. Of course, the discharge bin can also be replaced with a bottom-connected feed pipe, which is connected to the pressing and synthesis equipment for direct feeding; this is foreseeable.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a conveying pipe in conjunction with a stirring pipe, and utilizes the spiral conveying blades and spiral stirring blades inside each pipe to achieve the effect of conveying and stirring simultaneously. During quartz stone production, there is no need to wait for stirring time. It integrates the two processes of stirring and conveying, shortens the production time, and improves production efficiency.

[0015] 2. In this utility model, the stirring tube and the guide tube are set at the bottom of the conveying tube, which makes full use of the natural falling of the raw material under gravity, so that the raw material falls naturally into the guide tube and the stirring tube, without the need for power equipment to transfer it.

[0016] 3. The material guide tube in this utility model allows the raw material to be stirred to fall directly into the bottom of the stirring tube, and the raw material in the stirring tube forms a continuous stirring and flowing effect from bottom to top. In addition, the spiral structure of the spiral stirring blade can separate the upper and lower parts, avoiding the situation where the stirred raw material and the raw material to be stirred are directly mixed, which affects the stirring effect.

[0017] 4. The feeding hopper and discharging bin in this utility model facilitate feeding and discharging operations. At the same time, the bottom of the discharging bin is inclined, which makes it easier to collect and retrieve the material after discharge. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a quartz stone production raw material mixing device, mainly solving the problem that the current separate operation of mixing and transporting the raw materials to the synthesis station in quartz stone production is not conducive to improving production efficiency. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-6 Please provide a detailed explanation:

[0027] A quartz stone production raw material mixing device includes a conveying pipe 1, a concentric conveying shaft 4 installed inside the conveying pipe 1, a spiral conveying blade 5 fixed on the conveying shaft 4, shaft seats 6 installed inside the conveying pipe 1 at both ends of the conveying shaft 4, the two ends of the conveying shaft 4 being installed with the corresponding shaft seats 6, and a conveying motor 7 installed on the outer side of the rear end of the conveying pipe 1, the output end of the conveying motor 7 being fixedly connected to the corresponding conveying shaft 4.

[0028] A feed inlet 16 and a discharge outlet 17 are respectively opened on the upper rear side and the lower front side of the conveying pipe 1 at both ends of the conveying shaft 4. Multiple return ports 18 with equal spacing are opened at the bottom of the conveying pipe 1 between the feed inlet 16 and the discharge outlet 17. A distribution port 19 is opened at the bottom of the conveying pipe 1 behind each return port 18.

[0029] A stirring tube 2 is fixed at the bottom of the conveying pipe 1 at the return port 18. The stirring tube 2 is connected to the inside of the conveying pipe 1 through the return port 18. A fixing seat 10 is fixed at the bottom of the stirring tube 2. A stirring shaft 8 with the same center is installed inside the stirring tube 2. A spiral stirring blade 9 is fixed on the stirring shaft 8. The bottom of the stirring shaft 8 is installed with the fixing seat 10 at the corresponding position. A stirring motor 11 is installed below the fixing seat 10. The output end of the stirring motor 11 is fixedly connected to the stirring shaft 8 at the corresponding position. A through-hole 22 is opened on the bottom side of the stirring tube 2 facing the material outlet 19. A guide pipe 3 is fixed between the through-hole 22 and the material outlet 19. The conveying pipe 1, the guide pipe 3 and the stirring tube 2 are connected. The inner diameters of the conveying pipe 1, the stirring tube 2 and the guide pipe 3 decrease sequentially.

[0030] When in use, the quartz raw material is conveyed through the feed inlet 16. The conveying pipe 1 can be set horizontally or at an incline. When the raw material is poured into the conveying pipe 1 through the feed inlet 16, the conveying shaft 4 is driven to rotate by the conveying motor 7. The rotation of the spiral conveying blade 5 is used to convey the raw material in the conveying pipe 1 forward. At the same time, the raw material can be stirred and mixed to a certain extent by the spiral conveying blade 5.

[0031] When the raw materials pass through the distribution port 19, some of the raw materials fall into the guide pipe 3 and then into the mixing pipe 2. The mixing shaft 8 is driven to rotate by the mixing motor 11. At the same time, the spiral mixing blade 9 rotates to stir the raw materials in the mixing pipe 2, so that they are better mixed. While the spiral mixing blade 9 is rotating, its spiral structure carries the raw materials upward. At the same time, raw materials continue to fall into the guide pipe 3 to replenish the raw materials. The raw materials in the mixing pipe 2, after being stirred by the spiral mixing blade 9, re-enter the conveying pipe 1 through the return port 18 and are then conveyed by the spiral conveying blade 5, thus forming the effect of conveying and stirring at the same time. The stirred raw materials finally fall from the discharge port 17 for centralized collection and use.

[0032] The inner diameters of the conveying pipe 1, stirring pipe 2, and guide pipe 3 decrease sequentially to ensure that the amount of raw material entering the guide pipe 3 is less than the amount of raw material conveyed in the conveying pipe 1 at the current position. This ensures that only a portion of the raw material enters the guide pipe 3, while the rest continues to be conveyed. In addition, the raw material returns after being stirred in the stirring pipe 2, allowing for multiple stirrings and forming an orderly and stable cycle. If the diameter of the guide pipe 3 is larger than that of the stirring pipe 2, the large feed rate and small output rate will lead to material blockage, affecting the effect of conveying and stirring simultaneously. On the other hand, if the stirring pipe 2 and the guide pipe 3 have the same diameter as or larger than that of the conveying pipe 1, on the one hand, a larger amount of raw material remains in the stirring pipe 2, and on the other hand, multiple stirrings are still required. The larger the diameter, the larger the required component size, and the larger the design margin, resulting in more waste.

[0033] In some embodiments, a plurality of fixed platforms 20 with equal spacing are fixed at the bottom of the conveying pipe 1, a support frame 21 for ground support is fixed at the bottom of the fixed platform 20, a support column 13 for ground support is fixed at the bottom of the fixed seat 10, and a fixed frame 12 is fixed at the bottom of the fixed seat 10 corresponding to the position of the stirring motor 11, and the stirring motor 11 and the fixed frame 12 are installed and fixed.

[0034] The support frame 21 provides off-ground support for the conveying pipe 1, while also meeting the installation space requirements of the mixing pipe 2. The support column 13 increases the installation stability of the mixing pipe 2.

[0035] In some embodiments, a feed hopper 14 and a discharge bin 15 are fixed on the conveying pipe 1 at the positions corresponding to the feed inlet 16 and the discharge outlet 17, respectively, and the bottom part of the discharge bin 15 is inclined in the radial direction of the conveying pipe 1.

[0036] The feed hopper 14 and discharge bin 15 facilitate feeding and discharging operations. The bottom of the discharge bin 15 is inclined to obtain a better discharge position, making it convenient to use containers to collect and retrieve raw materials.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
