[0002] As an important material in the construction industry, dry-mixed mortar is produced using traditional continuous mixing devices that generally employ single-shaft or dual-shaft forced mixing structures. The mixing efficiency of these devices depends on the mechanical agitation of fixed blades, and traditional devices have many drawbacks.
[0003] Traditional dry-mix mortar mixing devices suffer from low mixing efficiency and uneven water-sand distribution. Furthermore, the open feeding hopper easily leads to significant dust emissions, polluting the environment and potentially harming worker health. In addition, existing equipment typically lacks an effective dust collection and treatment system, requiring additional dust removal equipment and increasing production costs. Moreover, the traditional mixing shaft structure is simple, making it prone to material blockage of internal channels, resulting in difficult maintenance and limited mobility, hindering its adaptability to different operational scenarios.

[0021] 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.
[0022] Reference Figures 1-3 An embodiment of this utility model provides a continuous mixing device for dry-mixed mortar production, including a support frame 1, an outer shell 2 fixedly connected to one side of the upper end of the support frame 1, a motor 3 fixedly connected to the side surface of the outer shell 2, a reducer 4 fixedly connected to the output end of the motor 3, the reducer 4 fixedly connected inside the outer shell 2, a mixing shaft 5 fixedly connected to the output end of the reducer 4, a conveying pipe 6 fixedly connected to the side surface of the outer shell 2 away from the motor 3, the conveying pipe 6 being sleeved outside the mixing shaft 5, a feeding bin 7 communicating with the outer surface of the conveying pipe 6, a dust removal component 8 being provided outside the feeding bin 7, and a mixing component 9 being provided outside the mixing shaft 5;
[0023] The dust removal assembly 8 includes a fixing plate 801, which is fixedly connected to the inside of the support frame 1. An absorption pump 802 is fixedly connected to the upper surface of the fixing plate 801. An absorption pipe 803 is connected to the input end of the absorption pump 802. An absorption head 804 is fixedly connected to the upper surface of the feeding bin 7. The absorption pump 802 is connected to the outer surface of the absorption head 804 through the absorption pipe 803.
[0024] A collection box 10 is fixedly connected to the upper surface of the fixed plate 2 901 away from the water pump 902. The output end of the absorption pump 802 passes through the fixed plate 1 801 and is connected to the upper surface of the collection box 10.
[0025] A filter screen 11 is fixedly connected to the side surface of the absorption head 804 away from the absorption tube 803.
[0026] The support frame 1 is internally rotatably connected to an auxiliary wheel 13, and the lower surface of the fixed plate 2 901 is fixedly connected to a caster 14.
[0027] Specifically, the device is moved to the working area using the auxiliary wheels 13 of the support frame 1 and the casters 14 of the fixed plate 901. Then, material is added to the feeding hopper 7. During the feeding process, the absorption pump 802 of the dust removal assembly 8 sucks in the dust generated in the feeding hopper 7 through the absorption pipe 803 and the absorption head 804 with a filter screen 11, and then transports it to the collection box 10 on the fixed plate 801. During this process, the filter screen 11 prevents large impurities from entering the absorption head 804, thus avoiding damage to the dust removal assembly 8. After the material is added, the device is activated. The motor 3 transmits its power to the mixing shaft 5 via the reducer 4, which reduces the speed and increases the torque. This causes the mixing shaft 5 to rotate, and the material in the conveying pipe 6 is initially mixed under the action of the mixing shaft 5. Then, the water pump 902 of the mixing component 9 introduces external water into the mixing shaft 5 through the water pipe 903 and the bearing 904. The water is sprayed out from the water outlet 905 in the opposite direction of the mortar flow, making full contact with the material. The mixing effect is enhanced by the stirring of the pin 906. In addition, the protective net 12 inside the mixing shaft 5 can prevent material from entering the shaft and damaging the equipment.
[0028] The mixing component 9 includes a second fixing plate 901, which is fixedly connected inside the support frame 1. The second fixing plate 901 is located below the first fixing plate 801. A water pump 902 is fixedly connected to the upper surface of the second fixing plate 901. The input end of the water pump 902 is connected to the outside. A water supply pipe 903 is provided at the output end of the water pump 902. One end of the water supply pipe 903 is connected to the output end of the water pump 902. The other end of the water supply pipe 903 passes through the delivery pipe 6 and is fixedly connected to a bearing 904. The bearing 904 is fixedly connected to the side surface of the stirring shaft 5. A water outlet hole 905 is opened on the outer surface of the stirring shaft 5. A pin 906 is fixedly connected to the outer surface of the stirring shaft 5.
[0029] The water outlet 905 flows in the opposite direction to the mortar flow.
[0030] A protective net 12 is fixedly connected inside the stirring shaft 5.
[0031] Specifically, when the mixing component 9 is working, the water pump 902 pressurizes the external water source and delivers it to the inside of the mixing shaft 5 through the water supply pipe 903. The water supply pipe 903 is flexibly connected to the rotating mixing shaft 5 through the bearing 904, which ensures smooth water flow and avoids mechanical interference. The water flows out in the opposite direction through the water outlet 905 opened on the outer surface of the mixing shaft 5, forming a counter-current effect with the sand flowing in the same direction, increasing the contact area and mixing degree between water and materials. In addition, the rotating mixing shaft 5 applies shear force to the materials through the pin 906, which, together with the counter-current water flow, forms a three-dimensional turbulent flow field, making the water and sand mix more evenly. Furthermore, the protective net 12 inside the mixing shaft 5 effectively intercepts large particulate impurities, preventing them from entering the shaft and causing mechanical wear or blockage, thus ensuring the long-term stable operation of the device.
[0032] Working principle: During use, the device is moved to the working area using auxiliary wheels 13 and casters 14, and then material is added to the feeding bin 7. Since dust is generated during feeding, the dust removal component 8 starts working, and the absorption pump 802 is activated. The dust is absorbed through the absorption pipe 803 and absorption head 804, and the filter screen 11 on the absorption head 804 prevents large particles from being sucked in, ensuring the normal operation of the absorption pump 802. The absorbed dust is transported by the absorption pump 802 to the collection box 10 for collection and processing. After the material is added, the motor 3 starts, and its output power is transmitted to the stirring shaft 5 after being reduced and increased in torque by the reducer 4, causing the stirring shaft 5 to open. The shaft 5 begins to rotate, and then the material is added from the feeding bin 7 into the conveying pipe 6. Driven by the rotating mixing shaft 5, it begins to be initially mixed. During the mixing process, the water pump 902 introduces external water, which is then transported to the inside of the mixing shaft 5 through the water pipe 903 and the bearing 904. The water is then sprayed out from the water outlet 905 on the outer surface of the mixing shaft 5. Since the water outlet 905 is in the opposite direction to the flow direction of the mortar, the water and mortar can come into more thorough contact and mix. The pins 906 on the outer surface of the mixing shaft 5 can further enhance the mixing effect, so that the mortar reaches a better mixing state. In addition, the protective net 12 fixed inside the mixing shaft 5 can prevent mortar from entering the mixing shaft 5 and causing damage.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
