Description

Technical Field

[0001] This invention relates to the field of mixing equipment technology, and in particular to a fast-hardening, early-strength dry-mixed mortar mixer and mixing process. Background Technology

[0002] Dry-mixed mortar is a commonly used material in construction engineering. Fast-setting and early-strength products are widely used in emergency repairs, reinforcement, and precast component production due to their rapid setting speed and high early strength. Traditional dry-mixed mortar mixing equipment is mostly of a general-purpose structure, which has obvious limitations in adapting to the production of fast-setting and early-strength mortar. It is difficult to meet the requirements of high-precision and high-stability industrial production, thus restricting product quality and construction efficiency.

[0003] In existing technologies, mixers generally lack raw material pretreatment and precise metering functions. Lumps and impurities in the raw materials can easily enter the mixing chamber, resulting in uneven mixing. At the same time, there is no closed-loop control in the feeding process, and the material ratio deviation is large, which directly affects the setting time and strength index of the rapid hardening and early strength mortar.

[0004] Conventional equipment does not integrate online sampling and real-time detection modules, making it impossible to monitor the uniformity and proportion of materials during the mixing process without stopping the machine. It can only rely on manual sampling and testing after the mixing is completed, which results in a strong lag in detection. It is also difficult to recycle unqualified materials in a timely manner, leading to a low finished product qualification rate. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a fast-hardening and early-strength dry-mixed mortar mixer and mixing process, so as to solve the problem that the existing mixers lack raw material pretreatment and accurate metering, and cannot monitor the uniformity and rationality of material ratio during the mixing process without stopping the machine, which affects the performance of the mortar.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fast-hardening, early-strength dry-mixed mortar mixer, comprising a mixing device, a support column installed on the top of the mixing device, a support base installed on the inner side of the support column, a filter screen installed on the top of the support base, a first telescopic checkweigher installed on the top of the mixing device, a feeding hopper installed on the top of the first telescopic checkweigher, the feeding hopper being located inside the support column and below the filter screen, a first baffle plate being opened on the top of the feeding hopper, a first cylinder being installed at the bottom of the first baffle plate, one end of the first cylinder being installed inside the first telescopic checkweigher, a baffle plate being installed on the top of the mixing device, a mixing motor being installed on one side of the mixing device, a gearbox being installed at the output end of the mixing motor, and mixing blades being installed at the output end of the gearbox for mixing materials; a sampling component being installed at the bottom of the mixing device for sampling materials without stopping the machine; an experimental component being installed at the bottom of the mixing device for real-time mixing of the sampled materials during their descent; and a discharge component being installed inside the mixing device for collecting the materials after mixing.

[0007] Optionally, the sampling component includes an observation box, which is installed on the bottom inner wall of the stirring device. Two sets of second telescopic checkweighers are installed at the bottom of the observation box, and a support box is installed on the top of the second telescopic checkweighers. A limit slide rail is installed on the inner wall of the support box, and a stirring box is installed on the top of the limit slide rail.

[0008] Optionally, a second cylinder is installed at the bottom of the observation box, a sampling shell is installed at the top of the second cylinder, a plug is fitted inside the sampling shell, and a partition plate is installed at the bottom of the plug.

[0009] Optionally, the top of the plug is made of a rubber ring, the bottom of the sampling housing is provided with a feeding pipe, and two connecting rods are installed on the outside of the second cylinder, while the connecting rods are installed on the first bearing and the second bearing.

[0010] Optionally, the experimental assembly includes a water tank installed on the bottom inner wall of the stirring device, a micro motor installed on the right side of the water tank, and a first pulley assembly installed at the bottom output end of the micro motor.

[0011] Optionally, a first drive shaft is installed on the right side of the first pulley assembly, a first bearing is sleeved on the bottom of the first drive shaft, and a stirring rod is installed on the bottom of the first bearing.

[0012] Optionally, a second pulley assembly is mounted on the top of the first drive shaft, a second drive shaft is mounted on the right side of the second pulley assembly, a second bearing is sleeved on the bottom of the second drive shaft, and a stirring rod is mounted on the bottom of the second bearing.

[0013] Optionally, a water outlet pipe is installed on the right side of the water tank, and a metering valve is installed on the outer side of the middle part of the water outlet pipe. The output end of the water outlet pipe is located above the mixing tank.

[0014] Optionally, the discharge assembly includes a second baffle installed inside the mixing device, a third cylinder installed at the bottom of the second baffle, the third cylinder installed on the support leg of the mixing device, the mixing device further includes a discharge bin installed on the support leg of the mixing device, the discharge bin has discharge ports at both ends, and a receiving bin is installed at the bottom of the discharge port.

[0015] This application also provides another technical solution, a mixing process for fast-hardening, early-strength dry-mixed mortar, the process steps of which are as follows: S1: The material is fed into the filter screen at the top of the support base inside the support column to filter out clumps and impurities, and the pure material falls into the feeding hopper; S2: The first telescopic checkweigher weighs the material in the feeding hopper in real time. After the formula weight is reached, the first cylinder drives the first baffle to open, and the material enters the mixing device. The baffle prevents the material from overflowing and dust from spreading. S3: The stirring motor starts and drives the stirring blades to rotate via the gearbox, thus fully mixing the materials; S4: After stirring to the preset state, the sampling component is started. The second cylinder pushes the sampling shell into the stirring device. The plug seals and the partition plate quantitatively samples. After sampling, the second cylinder descends and the sample falls into the mixing box through the feeding pipe. The second telescopic checkweigher weighs the sample and the limit slide rail fixes the position of the mixing box. S5: The experimental components operate synchronously. Water is added quantitatively to the water tank through the outlet pipe and metering valve according to the standard water-to-material ratio. The micro motor drives the first and second drive shafts to rotate through the first and second pulley sets, and drives the stirring rod to stir the sample through the first and second bearings, simulating the construction conditions. The staff monitors the sample status and early strength in real time through the observation box to determine whether the material is qualified. If it is not qualified, it is returned and stirred again. S6: After the material inspection is qualified, the discharge component is started, the third cylinder drives the second baffle to open, and the material flows into the receiving bin through the discharge bin and discharge port; after the discharge is completed, the third cylinder drives the second baffle to reset, and the equipment enters the preparation for the next batch of production.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a filter screen in conjunction with a first telescopic checkweigher, pretreatment is performed on the material before it enters the mixing device, effectively filtering out lumps and impurities in the raw materials and ensuring the purity of the material entering the mixing chamber. Simultaneously, the telescopic checkweigher is used to weigh the material in the feeding hopper in real time, and in conjunction with a cylinder-driven baffle structure, closed-loop control of the material ratio is achieved. This design solves the problem of uneven mixing caused by raw material lumps and ratio deviations in existing technologies, strictly ensuring the formulation accuracy of the fast-hardening, early-strength mortar, thereby ensuring that the mortar's setting time and early strength indicators meet production standards. This invention innovatively integrates sampling and experimental components, enabling automatic quantitative sampling without stopping the mixing process. During sampling, the linkage stirring mechanism descends into the mixing tank, working in conjunction with the water tank, metering valve, and weighing components in the experimental components. This allows for rapid addition and mixing of water to the sample according to the standard water-to-material ratio during sampling, reducing the sample's contact time with air, improving experimental accuracy, and simulating actual construction conditions in real time. Workers can monitor the mixing status and early strength development of the sample in real time through the observation box, quickly determining whether the material is qualified. This function overcomes the shortcomings of traditional equipment's delayed detection, allowing unqualified materials to be promptly returned for re-mixing, significantly improving the finished product qualification rate and ensuring batch quality consistency.

[0017] This invention employs a closed-loop design in the feeding, mixing, and discharging stages. During feeding, baffles prevent material spillage and dust diffusion; during discharging, cylinders drive the baffles to automatically open and close, allowing material to flow seamlessly into the receiving hopper without dust or residue. This fully automated, closed-loop production method not only effectively solves the problem of severe dust pollution from traditional equipment and improves the production environment, but also reduces manual intervention, achieving efficient and stable continuous production, thus meeting the dual demands of modern industry for environmental protection and efficiency.

[0021] like Figures 1 to 10As shown, an embodiment of the present invention provides a fast-hardening, early-strength dry-mixed mortar mixer, including a mixing device 1. A support column 10 is installed on the top of the mixing device 1, a support base 11 is installed inside the support column 10, a filter screen 12 is installed on the top of the support base 11, a first telescopic checkweigher 13 is installed on the top of the mixing device 1, a discharge bin 14 is installed on the top of the first telescopic checkweigher 13, the discharge bin 14 is located inside the support column 10 and below the filter screen 12, a first baffle 15 is opened on the top of the discharge bin 14, a first cylinder 16 is installed at the bottom of the first baffle 15, one end of the first cylinder 16 is installed inside the first telescopic checkweigher 13, a baffle plate 17 is installed on the top of the mixing device 1, a mixing motor 18 is installed on one side of the mixing device 1, a gearbox 19 is installed at the output end of the mixing motor 18, and mixing blades 190 are installed at the output end of the gearbox 19 for mixing materials; the mixing device... The bottom of the device 1 is equipped with a sampling component 2, which is used to sample materials without stopping the machine. The bottom of the mixing device 1 is equipped with an experimental component 3, which is used to stir the sampled materials in real time during the falling process. The mixing device 1 is equipped with a discharge component 4, which is used to collect the materials after the mixing is completed. The sampling component 2 is driven by the second cylinder 24 to automatically and quantitatively sample the materials from the sampling shell 25 and send them into the mixing box 23 through the discharge pipe 27. The second telescopic checkweigher 21 weighs the materials in real time. The experimental component 3 adds water quantitatively through the metering valve 390. The micro motor 31 drives the double stirring rod 35 through the transmission mechanism to simulate stirring and monitor the uniformity and early strength of the materials online. The discharge component 4 is driven by the third cylinder 41 to automatically open and close the second baffle 40. The materials enter the receiving hopper 44 in a sealed manner through the discharge bin 42 and the discharge port 43. There is no dust or residue, and continuous and stable production can be achieved, ensuring the consistency of mortar batch quality.

[0022] like Figures 8 to 10As shown, the sampling assembly 2 includes an observation box 20, which is installed on the bottom inner wall of the mixing device 1. Two sets of second telescopic checkweighers 21 are installed at the bottom of the observation box 20. A support box 22 is installed on the top of the second telescopic checkweighers 21. A limit rail 220 is installed on the inner wall of the support box 22. A mixing box 23 is installed on the top of the limit rail 220. A second cylinder 24 is installed at the bottom of the observation box 20. A sampling shell 25 is installed at the top of the second cylinder 24. A plug 26 is fitted inside the sampling shell 25. A partition plate 260 is installed at the bottom of the plug 26. The top of the plug 26 is made of a rubber ring. A discharge pipe 27 is opened at the bottom of the sampling shell 25. Two connecting rods 28 are installed on the outside of the second cylinder 24. The connecting rods 28 are mounted on the first bearing 34 and the second bearing 38. This sampling assembly 2... By setting an observation box 20 on the inner wall of the bottom of the mixing device 1, the sampling process can be visualized and monitored. Two sets of second telescopic checkweighers 21 installed at the bottom of the observation box 20 can accurately detect and control the weight of the sample entering the support box 22. The limit slide rail 220 ensures the stability of the mixing box 23 during the lifting process, so that it can accurately dock with the sampling material. The second cylinder 24 drives the sampling shell 25 and the internal plug 26 to move up and down. The plug 26 made of rubber ring material realizes the sealing and opening of the feed pipe 27. The quantitative sampling is completed in conjunction with the partition plate 260. The linkage design of the connecting rod 28 with the first bearing 34 and the second bearing 38 ensures the stability and reliability of the sampling mechanism, effectively avoids the leakage and residue of materials during the sampling process, and improves the accuracy of the test results.

[0023] like Figures 6 to 10 As shown, experimental component 3 includes a water tank 30, which is installed on the bottom inner wall of the stirring device 1. A micro motor 31 is installed on the right side of the water tank 30. A first pulley assembly 32 is installed at the bottom output end of the micro motor 31. A first drive shaft 33 is installed on the right side of the first pulley assembly 32. A first bearing 34 is sleeved at the bottom of the first drive shaft 33. A stirring rod 35 is installed at the bottom of the first bearing 34. A second pulley assembly 36 is installed at the top of the first drive shaft 33. A second drive shaft 37 is installed on the right side of the second pulley assembly 36. A second bearing 38 is sleeved at the bottom of the second drive shaft 37. The stirring rod 35 is installed at the bottom of the second bearing 38. A water outlet pipe 39 is installed on the right side, and a metering valve 390 is installed on the outer side of the middle of the water outlet pipe 39. The output end of the water outlet pipe 39 is located above the mixing tank 23. The experimental component 3 includes a water tank 30, a micro motor 31, a first pulley group 32, a first drive shaft 33, a first bearing 34, a stirring rod 35, a second pulley group 36, a second drive shaft 37, a second bearing 38, a water outlet pipe 39, and a metering valve 390. The micro motor 31 drives the double stirring rods 35 to rotate synchronously via the pulley group and the drive shaft. The metering valve 390 controls the quantitative addition of water to simulate the construction and mixing of the sample, monitors the mixing status and early strength in real time, and quickly determines the qualification of the material.

[0024] like Figure 4 , Figure 5 As shown, the discharge assembly 4 includes a second baffle 40, which is installed inside the mixing device 1. A third cylinder 41 is installed at the bottom of the second baffle 40 and is mounted on the support leg of the mixing device 1. The mixing device 1 also includes a discharge hopper 42, which is mounted on the support leg of the mixing device 1. The discharge hopper 42 has discharge ports 43 at both ends, and a receiving hopper 44 is installed at the bottom of the discharge ports 43. The discharge assembly 4 includes a second baffle 40, a third cylinder 41, a discharge hopper 42, a discharge port 43, and a receiving hopper 44. The third cylinder 41 drives the second baffle 40 to open and close automatically, with precise control and rapid response. After mixing, the material flows into the receiving hopper 44 through the discharge hopper 42 and the discharge port 43 in a sealed manner, without dust or spillage. After discharge, the material automatically resets, making it suitable for continuous and standardized production.

[0025] This application also provides another technical solution, a mixing process for fast-hardening, early-strength dry-mixed mortar, the process steps of which are as follows: S1: The material is fed into the filter screen 12 at the top of the inner support seat 11 of the support column 10 to filter out lumps and impurities, and the pure material falls into the feeding hopper 14. S2: The first telescopic checkweigher 13 weighs the material in the feeding hopper 14 in real time. After the formula weight is reached, the first cylinder 16 drives the first baffle 15 to open, and the material enters the mixing device 1. The baffle 17 prevents the material from overflowing and dust from spreading. S3: The stirring motor 18 starts and drives the stirring blades 190 to rotate via the gearbox 19, so as to fully stir and mix the materials; S4: After stirring to the preset state, the sampling component 2 is started, the second cylinder 24 pushes the sampling shell 25 into the stirring device 1, the plug 26 seals, the partition plate 260 quantitatively samples, after sampling, the second cylinder 24 descends, and the sample falls into the mixing box 23 through the feeding pipe 27; the second telescopic checkweigher 21 weighs the sample, and the limit slide rail 220 fixes the position of the mixing box 23. S5: Experimental component 3 operates synchronously. Water tank 30 adds water quantitatively according to the standard water-to-material ratio through water outlet pipe 39 and metering valve 390. Micro motor 31 drives first drive shaft 33 and second drive shaft 37 to rotate through first pulley group 32 and second pulley group 36. The first drive shaft 34 and second drive shaft 38 drive stirring rod 35 to stir the sample, simulating construction conditions. Staff monitor the sample status and early strength in real time through observation box 20 to determine whether the material is qualified. If it is not qualified, it is returned and stirred again. S6: After the material inspection is qualified, the discharge component 4 is started, the third cylinder 41 drives the second baffle 40 to open, and the material flows into the receiving bin 44 through the discharge bin 42 and the discharge port 43; after the discharge is completed, the third cylinder 41 drives the second baffle 40 to reset, and the equipment enters the preparation for the next batch of production.

[0026] The working principle of the technical solution provided by this invention is as follows: First, after starting the equipment, the staff put the material into the filter screen 12 above the support base 11 installed on the side of the support column 10 to filter impurities and lumps, ensuring that the raw materials entering the mixing chamber are pure and free of foreign objects. The filtered material falls into the feeding hopper 14, and the first telescopic checkweigher 13 installed on the top of the mixing device 1 weighs it in real time, strictly measuring according to the formula ratio to ensure that the proportion of each group meets the production standard of fast-hardening and early-strength mortar. After the set weight is reached, the first cylinder 16 drives the first baffle 15 to open, and the material enters the mixing device 1 at a uniform speed. The baffle 17 prevents the material from overflowing, avoiding spillage and waste during the feeding process. At the same time, the mixing motor 18 starts running, and the power is transmitted through the gearbox 19 and the speed is adjusted, driving the mixing blades 190 to make directional rotational motion inside the mixing device 1 to mix the material.

[0027] Then, after the stirring reaches the preset time, the sampling component 2 at the bottom of the stirring device 1 is automatically activated. The second cylinder 24 located inside the observation box 20 pushes the plug 26, which is initially located on the inner wall of the sampling shell 25, downward, opening the top of the plug 26 and forming a sealed structure with the sampling shell 25. At this time, the material falls downward from the slot at the top of the sampling shell 25 under gravity. The partition plate 260 stably controls the sampling amount. The sample falls into the stirring box 23 through the feeding pipe 27. At the same time, the two connecting rods 28 installed on the outside of the telescopic part of the second cylinder 24 simultaneously drive the first bearing 34 and the second bearing 38 to descend, so that the two stirring rods 35 descend into the stirring box 23. Meanwhile, the limiting slide rail 220 on the inner wall of the support box 22 is used to limit the position of the stirring box 23. The second telescopic checkweigher 21 at the bottom of the observation box 20 accurately weighs the sample, providing a data basis for experimental detection.

[0028] Simultaneously, experimental component 3 operates synchronously. Two water tanks 30 are connected to water outlet pipes 39 and metering valves 390, with water added in advance according to the standard water-to-material ratio. The micro motor 31 drives the first drive shaft 33 and the second drive shaft 37 to rotate synchronously via the first pulley group 32 and the second pulley group 36. The first bearing 34 and the second bearing 38 limit the rotation of the stirring rod 35. As the sample falls, the sample and water are thoroughly mixed until the second telescopic checkweigher 21 detects the set standard of the total weight of the pre-added water and sample. Then, the second cylinder 24 quickly pushes the plug 26 upward to form a sealing structure with the sampling shell 25, blocking the fall of the slurry and completing the sampling operation without stopping the machine.

[0029] Due to the quick-drying nature of mortar, it needs to be stirred rapidly during sampling to reduce contact time with air and maintain it in the state of the mixing device 1. This helps improve the accuracy of the test. Finally, after the mortar has dried quickly, simulating the on-site working conditions, the staff can pull out the mixing box 23 from the observation box 20 to view the mixing status and early strength development of the sample in real time, quickly determine whether the main mixing material is qualified, and return it to be remixed if it is not qualified, and enter the discharge process if it is qualified, so as to realize online real-time monitoring of mixing quality.

[0030] Once the sample and experimental testing determine that the material is qualified, the system automatically triggers the discharge command, the mixing device 1 quickly stops, and the internal discharge component 4 starts running. The third cylinder 41 installed on the support leg of the mixing device 1 drives the second baffle 40 to open downwards. The uniformly mixed material automatically flows into the discharge hopper 42 by gravity. The discharge hopper 42 has discharge ports 43 at both ends. The receiving hopper 44 below the discharge port 43 receives the finished material throughout the process and adopts a closed collection method. After the discharge is completed, the third cylinder 41 drives the second baffle 40 to reset, close the discharge channel, and the equipment automatically resets to prepare for the next batch of mixing production.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

10. A mixing process for fast-hardening, early-strength dry-mix mortar, applicable to the fast-hardening, early-strength dry-mix mortar mixer as described in claim 9, characterized in that, The process steps are as follows: S1: The material is fed into the filter screen (12) at the top of the inner support seat (11) of the support column (10) to filter out lumps and impurities, and the pure material falls into the feeding hopper (14). S2: The first telescopic checkweigher (13) weighs the material in the feeding hopper (14) in real time. After the formula weight is reached, the first cylinder (16) drives the first baffle (15) to open, and the material enters the mixing device (1). The baffle (17) prevents the material from overflowing and dust from spreading. S3: The stirring motor (18) starts and drives the stirring blades (190) to rotate through the gearbox (19) to fully stir and mix the materials; S4: After stirring to the preset state, the sampling component (2) is started, the second cylinder (24) pushes the sampling shell (25) into the stirring device (1), the plug (26) seals, the partition plate (260) takes quantitative samples, after sampling the second cylinder (24) descends, and the sample falls into the mixing box (23) through the feeding pipe (27); the second telescopic checkweigher (21) weighs the sample weight, and the limiting slide rail (220) fixes the position of the mixing box (23); S5: Experimental components (3) operate synchronously. Water tank (30) adds water quantitatively according to standard water-material ratio through water outlet pipe (39) and metering valve (390). Micro motor (31) drives first drive shaft (33) and second drive shaft (37) to rotate through first pulley group (32) and second pulley group (36). The first bearing (34) and second bearing (38) drive stirring rod (35) to stir the sample, simulating construction conditions. Staff monitor the sample status and early strength in real time through observation box (20) to determine whether the material is qualified. If it is not qualified, it is returned and stirred again. S6: After the material is inspected and qualified, the discharge assembly (4) is started, the third cylinder (41) drives the second baffle (40) to open, and the material flows into the receiving bin (44) through the discharge bin (42) and the discharge port (43); after the discharge is completed, the third cylinder (41) drives the second baffle (40) to reset, and the equipment enters the next batch of production preparation.
