Description

Technical Field

[0001] This utility model belongs to the technical field of cement production equipment, specifically relating to a cement composite powder production mixing device. Background Technology

[0002] In the cement production process, in order to improve the performance of cement and reduce production costs, it is often necessary to mix a variety of different raw materials to make cement composite powder. The cement composite powder production mixing device is the key equipment to realize this mixing process.

[0003] Currently, existing cement composite powder production mixing devices have many problems. On the one hand, the mixing is uneven. During the mixing process, raw materials with different densities and particle sizes are difficult to mix fully, resulting in unstable quality of the produced cement composite powder. This leads to problems such as inconsistent strength and asynchronous setting time in construction, affecting the quality of construction projects. The background of this problem is that as the construction industry continues to improve the requirements for cement quality, the attention to the uniformity of cement composite powder is increasing. Its impact covers the entire cement production industry and downstream construction fields. The key influencing factor is the unreasonable design of the mixing structure of the mixing device. The shape, number and distribution of the mixing blades cannot effectively drive the various raw materials to fully tumble and mix in the mixing chamber.

[0004] The patent application number "CN211800168U" describes a mixing device for seaweed and fruit / vegetable compound powder. The device includes a main body with a through-hole on its front. Two feed pipes are fixedly connected to the top of the main body, and a discharge pipe is fixedly connected to the bottom. A motor housing is fixedly connected to the top of the main body, and a rotary motor is fixedly installed inside the motor housing. A rotary bearing is fixedly installed on the inner top wall of the main body, and a rotating rod is movably installed inside the rotary bearing. This mixing device for seaweed and fruit / vegetable compound powder, by incorporating a motor housing, rotary motor, rotary bearing, rotating rod, U-shaped stirring column, and stirring rod on the main body, facilitates the rotation of the rotating rod within the main body via the rotary motor and rotary bearing. This rotation, in turn, drives the U-shaped stirring column and stirring rod to rotate, thereby horizontally mixing various powders within the main body.

[0005] The aforementioned patent describes a device with a motor housing, rotary motor, rotary bearing, rotary rod, U-shaped stirring column, and stirring rod on its main body. This allows the rotary rod to rotate inside the main body via the rotary motor and rotary bearing, which in turn drives the U-shaped stirring column and stirring rod to rotate, thereby horizontally stirring various powders inside the main body. However, the patent has certain limitations in its use. Existing stirring devices cannot break down and stir cement composite powder containing impurities, and the cement cannot be repeatedly sieved during the stirring process, making it difficult to make the cement composite powder finer. This results in unstable quality of the produced cement composite powder, which has a very adverse effect on the quality of construction projects. Utility Model Content

[0006] The purpose of this invention is to provide a cement composite powder production mixing device, which aims to solve the problem that existing mixing devices in the prior art cannot crush and mix cement composite powder containing impurities, and cannot repeatedly sieve the cement during the mixing process, making it difficult to make the cement composite powder finer. This results in unstable quality of the produced cement composite powder, which has an extremely adverse effect on the quality of construction projects.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cement composite powder production mixing device, comprising:

[0009] A stirring sleeve, wherein a support frame is fixedly connected to the circumferential surface of the stirring sleeve, a water storage tank is fixedly connected to the top of the support frame, and a connecting pipe and a water inlet pipe are fixedly connected to the top of the stirring sleeve.

[0010] A tapered connecting sleeve, which is fixedly connected to the top end of the connecting pipe;

[0012] A transmission mechanism is provided inside a conical connecting sleeve, and the transmission mechanism is used to transmit and crush large-particle cement composite powder.

[0013] As a preferred embodiment of this utility model, the transmission mechanism includes:

[0014] A connecting plate, which is fixedly connected to the circumferential surface of the connecting pipe;

[0015] A spiral conveyor blade, which is rotatably connected to a connecting plate;

[0016] Two crushing blades are provided, and both crushing blades are fixedly connected to the circumferential surface of the spiral conveyor blades;

[0017] The gears are provided in two, and the two gears are respectively fixedly connected to the spiral transmission blade and the transmission rod;

[0018] A stirring screen, wherein three stirring screens are provided, and all three stirring screens are fixedly connected to the circumferential surface of the transmission rod;

[0019] Discharge mixing blades, two of which are fixedly connected to the circumferential surface of the transmission rod;

[0020] A toothed belt, wherein the toothed belt is meshed with the circumferential surfaces of two gears;

[0021] A spiral stirring blade is fixedly connected to the circumferential surface of the transmission rod.

During the conveying process, the crushing blades cut and crush the large particles, realizing the function of crushing and mixing cement composite powder containing impurities. Furthermore, the mixing screen can repeatedly screen the material during mixing, making the cement composite powder finer and improving product quality.

Temperature and humidity sensors monitor the temperature and humidity of the mixing environment in real time, allowing operators to adjust the production process accordingly. Protective sleeves protect the toothed belt and gears, preventing external impurities from entering the transmission mechanism, ensuring stable equipment operation, and further guaranteeing the production quality of the cement composite powder.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1

[0040] Please see Figures 1-5 The present invention provides the following technical solution:

[0041] A cement composite powder production mixing device, comprising:

[0042] A stirring sleeve 1 is provided. A support frame 2 is fixedly connected to the circumferential surface of the stirring sleeve 1. A water storage tank 9 is fixedly connected to the top of the support frame 2. A connecting pipe 16 and a water inlet pipe 101 are fixedly connected to the top of the stirring sleeve 1.

[0043] A tapered connecting sleeve 6 is fixedly connected to the top end of the connecting pipe 16;

[0044] A transmission rod 14 is rotatably connected to the upper and lower inner walls of the stirring sleeve 1. A motor 15 is fixedly connected to the bottom end of the stirring sleeve 1, and the output end of the motor 15 is fixedly connected to the bottom end of the transmission rod 14.

[0045] The conveying mechanism is located inside the conical connecting sleeve 6 and is used to convey and crush large-particle cement composite powder.

[0046] In a specific embodiment of this utility model, the support frame 2 fixedly connected to the circumferential surface of the mixing sleeve 1 serves to support the mixing sleeve 1, ensuring the stability of the mixing sleeve 1 during operation and enabling the mixing process to proceed smoothly. The connecting pipe 16 fixedly connected to the top of the mixing sleeve 1 is used to connect with the conical connecting sleeve 6 to realize the transfer of materials; the water storage tank 9 stores the water that needs to be added during the mixing process, providing the necessary humidity conditions for the production of cement composite powder, which helps to optimize the mixing effect, promote better integration of raw materials, and improve the quality of cement composite powder.

[0047] The water inlet pipe 101 is used to introduce water from the water storage tank 9 into the mixing sleeve 1 to meet the water addition requirements during the mixing process, adjust the humidity of the cement composite powder, and improve the mixing quality.

[0048] The conical connecting sleeve 6 has a special conical structure that helps guide the material to flow to the conveying mechanism, improving the material handling efficiency of the conveying mechanism, while providing installation space for the conveying mechanism and ensuring that the conveying mechanism can work stably.

[0049] The transmission rod 14 rotates inside the mixing sleeve 1. By connecting to the output end of the motor 15, the rotational power of the motor 15 is transmitted to the inside of the mixing sleeve 1, driving the mixing components to mix the cement composite powder raw materials, thereby achieving material mixing.

[0050] The conveying mechanism is located inside the conical connecting sleeve 6 and performs the dual functions of conveying and crushing large-particle cement composite powder. During the conveying process, the large-particle cement composite powder output from the mixing sleeve 1 is transported to the designated position through its own mechanical structure. At the same time, the crushing component crushes the large particles to make their particle size meet the production requirements, thereby improving the uniformity and quality stability of the cement composite powder.

[0051] It should be noted that the specific models of warning lights 5, temperature and humidity sensors 3, and water tanks 9 used shall be selected by those skilled in the art. Furthermore, the warning lights 5, temperature and humidity sensors 3, and water tanks 9 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0052] Please refer to the details. Figures 1-5 The transmission mechanism includes:

[0053] Connecting plate 17 is fixedly connected to the circumferential surface of connecting pipe 16;

[0054] Spiral conveyor blade 19 is rotatably connected to the connecting plate 17;

[0055] Two crushing blades 20 are provided, and both crushing blades 20 are fixedly connected to the circumferential surface of the spiral conveyor blade 19.

[0056] Two gears 18 are provided, and the two gears 18 are respectively fixedly connected to the spiral transmission blade 19 and the transmission rod 14.

[0057] There are three stirring screens 12, and all three stirring screens 12 are fixedly connected to the circumferential surface of the transmission rod 14.

[0058] Discharge mixing blade 22, two discharge mixing blades 22 are provided, and both discharge mixing blades 22 are fixedly connected to the circumferential surface of the transmission rod 14;

[0059] Toothed belt 21 is meshed with the circumferential surfaces of two gears 18;

[0060] The spiral stirring blade 13 is fixedly connected to the circumferential surface of the transmission rod 14.

[0061] In this embodiment: After the motor 15 starts, its output end drives the transmission rod 14 to rotate. The spiral stirring blades 13 on the transmission rod 14 begin to stir the cement composite powder raw materials in the stirring sleeve 1, while the stirring screen 12 screens the material being stirred, and large particles are screened out. As the transmission rod 14 rotates, the gear 18 on the spiral conveyor blade 19 rotates through the toothed belt 21, thereby causing the spiral conveyor blade 19 to start rotating. The large particles of cement composite powder output from the connecting pipe 16 are conveyed by the spiral conveyor blade 19 along a specific direction. During the conveying process, the crushing blades 20 cut and crush the large particles. After the stirring is completed, the discharge stirring blades 22 assist in discharging the stirred cement composite powder through the discharge pipe 11, completing the entire cement composite powder production stirring and large particle processing process.

[0062] Please refer to the details. Figures 1-3 A transmission pipe 10 is installed at the water inlet of the water storage tank 9, and the transmission pipe 10 is fixedly connected to the circumferential surface of the water inlet pipe 101.

[0063] In this embodiment: In actual operation, when it is necessary to add water to the cement composite powder during the mixing process to optimize the mixing effect, the water stored in the water storage tank 9 flows into the water inlet pipe 101 through the transmission pipe 10, and then enters the mixing sleeve 1. This connection method ensures that the water source can be stably and accurately delivered to the mixing area, closely cooperating with the mixing process and meeting the humidity control requirements of cement composite powder production.

[0064] Please refer to the details. Figure 2 The bottom end of the mixing sleeve 1 is fixedly connected to the discharge pipe 11, and the support frame 2 is fixedly connected to the connecting seat 4.

[0065] In this embodiment: after mixing is completed, the mixed cement composite powder is discharged from the mixing sleeve 1 through the discharge pipe 11. The connecting seat 4 provides support and fixation for the discharge pipe 11, ensuring the stability of the discharge process and preventing the discharge pipe 11 from shaking or being damaged due to force when the material is discharged.

[0066] Please refer to the details. Figures 1-5 The circumferential surface of the tapered connecting sleeve 6 is hinged to a cover plate 7 via a hinge shaft. The top end of the tapered connecting sleeve 6 is fixedly connected to a protective sleeve 8, which is fitted onto the outside of the toothed belt 21 and the two gears 18.

[0067] In this embodiment, the protective sleeve 8 is fitted over the outside of the toothed belt 21 and the two gears 18. During equipment operation, when maintenance or cleaning of the transmission mechanism is required, the cover plate 7 can be opened via the hinge, facilitating inspection and cleaning of components such as the conical connecting sleeve 6 and the spiral transmission blade 19 by operators. The protective sleeve 8 serves to protect the toothed belt 21 and the two gears 18, preventing external impurities from entering the transmission mechanism and affecting the stability and accuracy of power transmission.

[0068] Please refer to the details. Figures 1-3 A warning light 5 is fixedly connected to the circumferential surface of the stirring sleeve 1.

[0069] In this embodiment, the warning light 5 can emit different signals according to the operating status of the equipment. For example, when the equipment malfunctions or encounters an abnormal situation, the warning light 5 will illuminate red to remind the operator to check and repair it in a timely manner; when the equipment is operating normally, the warning light 5 can illuminate green to allow the operator to intuitively understand the working status of the equipment.

[0070] Please refer to the details. Figures 1-5 A temperature and humidity sensor 3 is fixedly connected to the circumferential surface of the stirring sleeve 1, and the detection end of the temperature and humidity sensor 3 is connected to the stirring sleeve 1.

[0071] In this embodiment, the temperature and humidity sensor 3 monitors the temperature and humidity of the cement composite powder in the mixing sleeve 1 in real time during the mixing process. Temperature and humidity have a significant impact on product quality during the production of cement composite powder. Through the detection of the temperature and humidity sensor 3, operators can promptly understand the changes in temperature and humidity in the mixing environment and adjust the production process as needed. For example, by adjusting the water addition rate of the water tank 9 or controlling the operating parameters of the equipment, the mixing process can be ensured to proceed under suitable temperature and humidity conditions, thereby improving the quality stability of the cement composite powder.

[0072] The working principle and usage process of this utility model are as follows: When using this cement composite powder production mixing device, first turn on the motor 15, whose output end drives the transmission rod 14 to rotate, so that the spiral mixing blade 13 stirs the cement composite powder raw material in the mixing sleeve 1; at the same time, the mixing screen 12 screens out large particles, and the screened large particles enter the conical connecting sleeve 6 through the connecting pipe 16. The rotation of the transmission rod 14 drives the gear 18, which in turn drives the spiral transmission blade 19 to rotate through the toothed belt 21, thereby conveying the large particles, and the crushing blade 20 cuts and breaks them up during the process. If humidity needs to be adjusted, the water in the water storage tank 9 flows into the mixing sleeve 1 through the transmission pipe 10 and the water inlet pipe 101. After the mixing is completed, the discharge mixing blade 22 assists the material to be discharged through the discharge pipe 11, and the connecting seat 4 serves to support and fix the discharge pipe 11. During the mixing process, the temperature and humidity sensor 3 monitors the temperature and humidity in real time, and the operator adjusts the production process accordingly. The warning light 5 displays the equipment operating status; if the transmission mechanism needs to be maintained, the cover plate 7 can be opened. The protective cover 8 can prevent impurities from entering the transmission mechanism and ensure the stable operation of the equipment.

[0073] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
