Description

Technical Field

[0001] The present invention relates to the field of dry-mix mortar preparation, and more particularly to a high-efficiency dry-mix mortar mixing device. Background Art

[0002] Dry-mix mortar is a building material made by mixing cement, sand, and mineral additives in a certain proportion. This mortar has the characteristics of stable quality, easy construction, and good durability. It is widely used in building wall masonry, plastering, ground leveling, waterproofing projects and other fields. The mixing process of dry-mix mortar is usually completed in professional production factories to ensure the accurate proportion of each component and uniform mixing, thereby guaranteeing the quality and performance of the final product.

[0003] The mixing process of dry-mix mortar is divided into factory pre-mixing and construction site mixing. Factory pre-mixing: In the factory, raw materials such as cement, sand (which needs to be screened to remove oversized particles), mineral additives, etc. need to be preliminarily mixed and evenly distributed in a specific proportion and packaged in the form of dry powder; Construction site mixing: When used at the construction site, just add an appropriate amount of water to the dry-mix mortar and stir it before use.

[0004] During the pre-mixing process in the factory, since the raw materials to be mixed are in fine powder form and have a high specific surface area, whether they are added manually or automatically, when a large amount of dry powder raw materials quickly enter the mixing equipment, it will cause strong air disturbances and be affected by the air flow and suspended in the air, resulting in flying dust. This situation not only leads to an imbalance in the proportions of certain key ingredients, affecting the performance indicators of the final product, but also significantly reduces the air quality in the workshop, thereby causing workers to suffer from respiratory diseases. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide an efficient dry mortar mixing equipment, which can achieve a negative pressure state in the mixing box, so that the dust generated when adding materials will not fall outward. At the same time, the raw materials can be pre-treated and broken up, and the fluidity of the raw material particles can be improved, so that the raw materials are evenly dispersed in the mixing box, which can effectively improve the mixing effect.

[0009] Furthermore, a circular tube shell is provided on the lower side of the dispersion frame, and the circular tube shell is fixedly installed on the bottom wall of the inner cavity of the mixing box. An auger is rotatably installed in the circular tube shell, and the auger is rotatably installed on the bottom wall of the inner cavity of the mixing box. The output end of the motor on the lower side is fixedly installed on the bottom end of the auger, and scrapers are uniformly provided on the inner wall of the mixing box. Each group of scrapers is fixedly installed on the top of the auger, and each group of scrapers is evenly fixed with a stirring rod on the side close to the circular tube shell.

[0010] Furthermore, a fixed tube is provided on one side of the dispersion frame, and the fixed tube is fixedly installed on the connecting piece between the auger and one group of the scrapers. A fixed block is slidably installed in the end of the fixed tube close to the dispersion frame, and a return spring is fixedly installed between the fixed block and the inner cavity wall of the fixed tube. Balls are rollingly installed on the end of the fixed block close to the dispersion frame, and grooves compatible with the balls are evenly opened on the outer wall of the dispersion frame.

[0011] Furthermore, both groups of the motors are provided with annular wind wheels on the outside, and the two groups of the annular wind wheels are respectively rotatably mounted on the top and bottom of the mixing box.

[0013] Furthermore, a fan blade is rotatably mounted on the filter plate, the fan blade is arranged in the inner cavity of the mounting tube, a brush plate is provided on the side of the filter plate away from the fan blade, and the brush plate is fixedly mounted to one end of the fan blade.

[0014] Furthermore, the brush plate is hollow, and arc blocks are evenly fixedly installed on the inner cavity wall of the brush plate, and a movable ball is provided on the top of the arc block on the lower side.

[0015] Furthermore, the initial state of the return spring is a compressed state.

[0016] Furthermore, a discharge pipe is fixedly installed on one side of the bottom of the mixing box, and the discharge pipe is connected to the inner cavity of the mixing box.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) This solution generates suction on the inner cavity of the feed pipe through the fan, which can prevent the dust generated during the feeding from falling to the outside, balance the proportion of raw material components, and improve the quality of the final dry mortar. It can not only improve the air quality of the workshop, but also improve the physical and mental health of the workers. By driving the breaking rod to rotate, the raw materials will be pre-processed and broken up, which can avoid the raw materials from being piled up for a long time or agglomerating due to environmental factors, which makes it difficult to disperse the raw materials evenly. By driving the cross plate to rotate by the rotating rod, the pre-processed and broken up raw materials can be evenly diffused into the inner cavity of the mixing box, which can make the raw material particles evenly distributed, thereby improving the mixing effect.

[0018] (2) In this solution, when the fan blows air to the outside through the mounting pipe, the gas will also be discharged into the air storage chamber through the air outlet pipe. The gas will be discharged into the fixed chamber through the cavity and finally discharged downward through the exhaust hole. The exhaust hole can blow air downward while the breaking rod rotates. When the breaking rod rotates to break up the raw materials, the exhaust hole will generate a downward blowing force on the broken raw materials. Blowing helps to improve the fluidity of the raw material particles, especially for powder materials that are easy to agglomerate or have a high friction coefficient. Blowing can help disperse the raw materials and promote more uniform entry into the mixing box, further improving the dispersion effect of the raw materials, thereby improving the mixing effect.

[0019] (3) This solution stirs the raw materials on the outside of the circular tube shell by rotating each group of stirring rods, which can improve the fluidity of the raw materials in the mixing box and make the raw materials in the mixing box flow to the lower side of the circular tube shell. The raw materials on the bottom wall of the mixing box cavity are transported back and forth upward in the circular tube shell by the rotation of the auger. The raw materials are discharged back and forth into the mixing box, which can effectively improve the mixing efficiency of the raw materials and avoid the situation where the raw materials are closely attached to the bottom wall of the mixing box cavity and are difficult to be effectively reached by the agitator, thereby effectively improving the mixing effect of the raw materials.

[0020] (4) In this scheme, when the fixed tube drives the ball to make a circular motion around the dispersion frame through the fixed block, the ball can reciprocate and hit the inner cavity of the groove and generate vibration on the dispersion frame, thereby improving the fluidity of the raw materials on the inner cavity wall of the dispersion frame and preventing the raw materials from adhering to the inner cavity wall of the dispersion frame. At the same time, the downward blowing of each group of exhaust holes can effectively discharge the remaining raw materials into the inner cavity of the mixing box, thereby improving the accuracy of the raw materials and avoiding the situation where a certain raw material is actually unbalanced in proportion, thereby effectively improving the performance indicators of the final dry powder mortar.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] See also Figures 1 to 7 , a dry mortar high-efficiency mixing device, comprising a mixing box 1, a mounting pipe 2 is fixedly installed on one side of the mixing box 1, and the mounting pipe 2 is connected to the outside; Also includes: The suction assembly includes a fan 3 fixedly installed in the mounting tube 2, a dispersion frame 4 fixedly installed on the top wall of the inner cavity of the mixing box 1, a feed pipe 5 fixedly installed on one side of the top of the mixing box 1, and the feed pipe 5 is connected to the dispersion frame 4. A filter plate 30 is fixedly installed on the side of the inner cavity of the mounting tube 2 close to the mixing box 1; Pretreatment component, the pretreatment component includes a rotating rod 6 arranged in the dispersion frame 4, the rotating rod 6 is rotatably installed on the top of the mixing box 1, the top and bottom of the mixing box 1 are fixedly installed with motors 7, the output end of the upper motor 7 is fixedly installed with the top of the rotating rod 6, and the breaking up rods 8 are evenly fixedly installed on the rod wall of the rotating rod 6. A cross plate 9 is fixedly installed at the bottom end of the rotating rod 6, and a blowing component is arranged in the rotating rod 6.

[0025] The blowing assembly includes a cavity 10 opened in the rotating rod 6, an air storage chamber 11 opened in the top of the mixing box 1, the cavity 10 is connected to the inner cavity of the air storage chamber 11, and a fixed cavity 13 is opened in each group of breaking up rods 8, and each group of fixed cavities 13 is connected to the inner cavity of the cavity 10. Exhaust holes 14 are evenly opened at the bottom of each group of breaking up rods 8, and each group of exhaust holes 14 is connected to the inner cavity of the adjacent fixed cavity 13. An air outlet pipe 12 is fixedly installed on the side of the inner cavity wall of the mounting tube 2 away from the mixing box 1, and the other end of the air outlet pipe 12 passes through the mounting tube 2 and the mixing box 1 and is connected to the inner cavity of the air storage chamber 11.

[0026] First, open the sealing cover on the top of the feed pipe 5, and then turn on the fan 3 and the upper motor 7. When the fan 3 works, it will absorb the gas in the inner cavity of the mixing box 1 through the installation pipe 2 and then discharge it to the outside through the installation pipe 2, so that the inner cavity of the mixing box 1 forms a negative pressure state. The inner cavity of the mixing box 1 will generate suction to the feed pipe 5 through the dispersion frame 4. Then the staff will pour the raw materials such as cement, sand and mineral additives in a specific proportion into the feed pipe 5. These raw materials will be discharged into the dispersion frame 4 through the feed pipe 5. At this time, under the action of the fan 3, suction will be generated on the inner cavity of the feed pipe 5, and the raw materials will be discharged into the dispersion frame 4. After the material enters the feeding pipe 5, the dust raised by it will not be lifted up and fall to the outside, but will be sucked into the inner cavity of the mixing box 1 through the dispersion frame 4. The raw materials entering the mixing box 1, and part of the dust generated by it will flow with the airflow in the mixing box 1. These dusts will be intercepted when passing through the filter plate 30, and the filtered gas will be discharged to the outside through the installation pipe 2, which can avoid the dust flying when adding materials, balance the proportion of raw materials, improve the quality of the final dry mortar, not only improve the air quality of the workshop, but also improve the physical and mental health of workers; When the upper motor 7 is working, its output end will drive the rotating rod 6 to rotate rapidly. When the rotating rod 6 rotates, it will drive each group of scattering rods 8 to rotate synchronously. When the raw materials are discharged into the dispersion frame 4 through the feeding pipe 5, the rotation of each group of scattering rods 8 will scatter these raw materials, playing the role of pre-treatment and scattering, which can avoid the raw materials from being piled up for a long time or agglomerating due to environmental factors, thereby making it difficult to evenly disperse the raw materials, making the component ratio in some areas inconsistent with the design requirements, and ultimately affecting the quality consistency of the entire batch. At the same time, when different raw materials are poured together, the effect of preliminary mixing can be achieved, thereby effectively improving the mixing efficiency of the raw materials; when the rotating rod 6 rotates, it will also drive the cross plate 9 to rotate synchronously, and the rotation of the cross plate 9 can realize the uniform diffusion of the pre-treated scattered raw materials into the inner cavity of the mixing box 1, which can make the raw material particles evenly distributed, effectively improving the uniform dispersion effect of the raw materials, thereby improving the mixing effect; When the fan 3 absorbs the gas in the mixing box 1 and blows air to the outside through the mounting tube 2, the right end of the mounting tube 2 is set to a small aperture. When the fan 3 blows the air out through the small aperture, the gas will also be discharged into the outlet pipe 12. The gas in the outlet pipe 12 will be discharged into the cavity 10 through the air storage chamber 11, and the gas in the cavity 10 will be discharged into the fixed chamber 13 and finally discharged downward through each group of exhaust holes 14. At this time, each group of breaking up rods 8 will also blow air downward through each group of exhaust holes 14 while rotating. When the breaking up rods 8 rotate to break up the raw materials, the exhaust holes 14 will generate a downward blowing force on the broken up raw materials. Blowing helps to improve the fluidity of the raw material particles, especially for powder materials that are easy to agglomerate or have a high friction coefficient. Blowing can help disperse the raw materials and promote more uniform entry into the mixing box 1, further improving the dispersion effect of the raw materials, thereby improving the mixing effect.

[0027] like Figure 3 As shown, a circular tube shell 15 is provided on the lower side of the dispersion frame 4, and the circular tube shell 15 is fixedly installed on the bottom wall of the inner cavity of the mixing box 1. An auger 16 is rotatably installed in the circular tube shell 15, and the auger 16 is rotatably installed on the bottom wall of the inner cavity of the mixing box 1. The output end of the lower side motor 7 is fixedly installed on the bottom end of the auger 16, and scrapers 18 are evenly provided on the inner wall of the mixing box 1. Each group of scrapers 18 is fixedly installed on the top of the auger 16, and a stirring rod 19 is evenly fixedly installed on the side of each group of scrapers 18 close to the circular tube shell 15.

[0028] The raw materials initially dispersed in the dispersion frame 4 will fall into the mixing box 1, and the motor 7 on the lower side will be turned on. The output end of the lower motor 7 will drive the auger 16 to rotate. The rotation of the auger 16 will drive each group of scrapers 18 and each group of stirring rods 19 to rotate. The rotation of each group of scrapers 18 will scrape the inner wall of the mixing box 1 to prevent the raw materials from adhering to the inner wall of the mixing box 1, and at the same time avoid the situation where the raw materials in the dead corners are difficult to be mixed. The rotation of the auger 16 will transport the raw materials on the bottom wall of the inner cavity of the mixing box 1 upward in the round tube shell 15, and the raw materials will eventually pass through The top of the circular tube shell 15 falls into the mixing box 1 again, and the raw materials on the outside of the circular tube shell 15 are stirred by the rotation of each group of stirring rods 19, which can improve the fluidity of the raw materials in the mixing box 1, so that the raw materials in the mixing box 1 flow to the lower side of the circular tube shell 15, so that the auger 16 can transport the raw materials at the bottom of the inner cavity of the mixing box 1 back and forth upward, and discharge them into the mixing box 1 again, which can effectively improve the mixing efficiency of the raw materials, avoid the situation where the raw materials are close to the bottom wall of the inner cavity of the mixing box 1 and are difficult to be effectively reached by the agitator, and can effectively improve the mixing effect of the raw materials.

[0029] like Figure 5As shown, a fixed tube 20 is provided on one side of the dispersion frame 4, and the fixed tube 20 is fixedly installed on the connecting piece between the auger 16 and one group of scrapers 18. A fixed block 23 is slidably installed in the end of the fixed tube 20 close to the dispersion frame 4, and a return spring 22 is fixedly installed between the fixed block 23 and the inner cavity wall of the fixed tube 20. A ball 24 is rollingly installed on the end of the fixed block 23 close to the dispersion frame 4, and grooves 25 adapted to the ball 24 are evenly opened on the outer wall of the dispersion frame 4.

[0030] When the lower motor 7 drives the auger 16 to rotate, the auger 16 drives the fixed tube 20 to move synchronously through the connection between it and one group of scrapers 18. The fixed tube 20 drives the ball 24 to make a circular motion on the outer wall of the dispersion frame 4 through the fixed block 23. When the ball 24 moves out of the adjacent groove 25, the ball 24 pushes the fixed block 23 in one end of the fixed tube 20 to slide to the side away from the dispersion frame 4 and squeeze the return spring 22. When the ball 24 rolls on the outer wall of the dispersion frame 4 to the position of the next group of grooves 25, under the action of the return spring 22, the return spring 22 returns to its initial state and pushes the fixed block 23 to drive the ball 24 to the adjacent groove 25. It slides near one side of the dispersion frame 4 and moves into the inner cavity of the groove 25. At this time, the fixed tube 20 drives the ball 24 to make a circular motion around the dispersion frame 4 through the fixed block 23. The ball 24 can reciprocate and hit the inner cavity of the groove 25 and generate vibrations on the dispersion frame 4, which can improve the fluidity of the raw materials on the inner cavity wall of the dispersion frame 4 and avoid the raw materials from adhering to the inner cavity wall of the dispersion frame 4. At the same time, the downward blowing of each group of exhaust holes 14 can effectively discharge the remaining raw materials into the inner cavity of the mixing box 1, thereby improving the accuracy of the raw materials and avoiding the situation where a certain raw material is actually unbalanced in proportion, thereby effectively improving the performance indicators of the final dry powder mortar.

[0031] like Figure 3 and Figure 4 As shown, an annular wind wheel 27 is provided on the outside of the two groups of motors 7, and the two groups of annular wind wheels 27 are rotatably installed on the top and bottom of the mixing box 1 respectively. Agitating blades 28 are evenly fixedly installed on the side of the two groups of annular wind wheels 27 away from the mixing box 1, and a protective frame 26 is provided on the outside of the two groups of annular wind wheels 27, and the two groups of protective frames 26 are fixedly installed on the top and bottom of the mixing box 1 respectively.

[0032] Two groups of exhaust pipes 29 are fixedly installed on the side of the inner cavity wall of the mounting tube 2 away from the mixing box 1. The other ends of the two groups of exhaust pipes 29 pass through the mounting tube 2 and the adjacent protective frame 26, and are connected to the inner cavity of the adjacent protective frame 26. One end of the two groups of exhaust pipes 29 close to the adjacent protective frame 26 is facing one side of the adjacent circular wind wheel 27, and the inner cavities of the two groups of protective frames 26 are connected to the outside world.

[0033] When the fan 3 blows air to the outside through the mounting pipe 2, the gas in the mounting pipe 2 will also be discharged into the upper and lower exhaust pipes 29. The gas in the upper and lower exhaust pipes 29 will be discharged into the protective frames 26 on the upper and lower sides respectively. The gas flows in the protective frame 26 and will eventually be discharged to the outside, which plays a role in ventilating the protective frame 26. By having the other end of the exhaust pipe 29 facing one side of the annular wind wheel 27, the exhaust pipe 29 can blow the annular wind wheel 27 to rotate when blowing air. When the annular wind wheel 27 rotates, it will drive the groups of stirring blades 28 thereon to rotate synchronously. The rotation of each group of stirring blades 28 will uniformly stir the gas in the protective frame 26, thereby improving the fluidity of the gas in the protective frame 26 and making the temperature of the gas in the protective frame 26 uniform, thereby achieving uniform cooling of the motor 7, effectively improving the cooling effect of the motor 7, and avoiding the temperature increase during its operation, thereby effectively improving the working performance of the motor 7, and thus improving the working effect of the motor 7.

[0034] like Figure 3 and Figure 5 As shown, a fan blade 31 is rotatably mounted on the filter plate 30 , and the fan blade 31 is arranged in the inner cavity of the mounting tube 2 . A brush plate 32 is provided on the side of the filter plate 30 away from the fan blade 31 , and the brush plate 32 is fixedly mounted on one end of the fan blade 31 .

[0035] The brush plate 32 is hollow, and arc blocks 17 are evenly fixedly mounted on the inner wall of the brush plate 32 . The top of the lower arc block 17 is contacted with a movable ball 21 .

[0036] When the fan 3 draws the gas in the mixing box 1 into the installation pipe 2, the gas flowing in the installation pipe 2 will drive the fan blades 31 to rotate when passing through the fan blades 31. When the fan blades 31 rotate, the brush plate 32 will be driven to rotate synchronously, so that the brush plate 32 can rotate to clean the raw materials remaining on the filter plate 30, which can prevent the filter plate 30 from being blocked, thereby improving the gas circulation, and can improve the effect of the fan 3 on sucking air into the mixing box 1. When the brush plate 32 rotates, under the gravity of the movable ball 21 itself, it will always be on the bottom wall of the inner cavity of the brush plate 32. Through the setting of multiple groups of arc blocks 17, the movable ball 21 will roll on each group of arc blocks 17. The movable ball 21 can vibrate the brush plate 32 when rolling, which can shake off the raw materials remaining on the brush plate 32, thereby improving the cleaning effect, and the cleaned raw materials will fall into the mixing box 1.

[0037] like Figure 3 and Figure 5 As shown, the return spring 22 is in a compressed state in its initial state.

[0038] A discharge pipe 33 is fixedly mounted on one side of the bottom of the mixing box 1 , and the discharge pipe 33 is communicated with the inner cavity of the mixing box 1 .

[0039] By compressing the return spring 22 in its initial state, the ball 24 can be tightly attached to the inner cavity of the groove 25, so that the ball 24 can impact the inner cavity of the groove 25. After the raw materials in the mixing box 1 are stirred and mixed, the discharge pipe 33 is opened to take out the mixed dry mortar and package it.

[0040] Working principle: first open the sealing cover on the top of the feed pipe 5, turn on the fan 3, the fan 3 will generate suction on the feed pipe 5 through the mixing box 1, and when the raw materials are poured into the feed pipe 5, no dust will float to the outside. While the fan 3 blows air to the outside through the mounting tube 2, it will cause the various exhaust holes 14 on the beating rod 8 to blow air downward, turn on the upper motor 7, the upper motor 7 will drive the beating rod 8 to rotate through the rotating rod 6, the rotation of the beating rod 8 will evenly break up the raw materials discharged from the feed pipe 5, and the raw materials will be further dispersed by blowing air through the exhaust holes 14. The rotation of the rotating rod 6 will also drive the cross plate 9 to rotate to evenly spread the pre-treated raw materials in the mixing box 1, turn on the lower motor 7, the lower motor 7 will drive the scraper 18 and the stirring rod 19 to rotate through the auger 16 to evenly mix the raw materials in the mixing box 1. The auger 16 rotates to transport the raw materials at the bottom of the mixing box 1 back and forth upward to improve the mixing effect. During the stirring, the fixed tube 20 drives the ball 24 to reciprocate and hit the dispersion frame 4, which can improve the flow of the raw materials in the dispersion frame 4 to avoid residue. While the installation tube 2 is exhausted, the exhaust pipe 29 will also be used to blow and ventilate the protective frame 26. The stirring sheet 28 can achieve uniform cooling of the motor 7. While the gas flows in the installation tube 2, the fan blades 31 will drive the brush plate 32 to rotate to clean the filter plate 30 to prevent the filter plate 30 from being blocked. When the brush plate 32 rotates, it will generate self-vibration through the cooperation of the movable ball 21 and the arc block 17, which can shake off the raw materials remaining on it. After the raw materials in the mixing box 1 are stirred and mixed, open the discharge pipe 33 and take out the mixed dry powder mortar for packaging.
