Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a material mixer for building construction engineering. Background Art

[0002] A mixer is a construction machinery, mainly used to mix cement, sand, various dry mortar and other construction materials. It is a machine with a bladed shaft rotating in a cylinder or trough to mix and mix a variety of raw materials to make them into a mixture or a suitable consistency. This equipment is often needed in the processing of concrete. In the process of concrete processing, it is often necessary to add raw materials such as cement, sand, aggregate and water into the mixer according to the proportion. The quality of water has a direct impact on the performance of concrete, especially in the concrete mixing process. The pH value of water is an important parameter, which is directly related to the stability and durability of concrete. Excessively acidic or alkaline water will react chemically with cement, which may cause concrete cracking, strength reduction and other adverse effects. Therefore, in the process of concrete mixing, the pH value of water often needs to be treated, so that the pH value of the water used for mixing is generally not less than 6.5 and not greater than 8.5;

[0003] The existing method of measuring the pH value of water quality is often to measure it through measuring equipment. When the pH value is found to be too high or too low, the acid-base solution is poured out by opening the valve controlling the acid-base solution for adjustment. Although this process can also neutralize the pH value of the water, it lacks real-time feedback and continuous adjustment mechanism. The existing method is often difficult to achieve precise pH value control, and the amount of acid-base solution added may be inaccurate, resulting in excessive or insufficient pH value adjustment. Summary of the invention

[0004] The object of the present invention is to provide a material mixer for building construction engineering to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides a material mixer for construction of housing construction projects, comprising a mounting base, a mixer body connected to the mounting base and a feed frame connected to the mixer body, the feed frame is provided with a water quality adjustment component, the water quality adjustment component comprises a water tank connected to the feed frame, the water tank is connected to a plurality of acid and alkali solution storage tanks, one side of the water tank is connected to a potential-current converter, the water tank is connected to a pH meter, and the water tank is also provided with an equal amount adjustment component that is adjusted synchronously with the pH meter.

[0010] Furthermore, two mutually symmetrical guide blocks are connected to the first blocking plate, and the other side of the guide block is slidably connected in the connecting frame, and a sliding groove for the guide block to slide is provided in the connecting frame.

[0011] Furthermore, a guide rod is connected inside the connection frame, the connection nut is slidably connected to the guide rod, and a sliding opening for the guide rod to slide is provided on the connection nut.

[0012] Furthermore, a filter screen is detachably connected to the feed inlet of the mounting base via screws, and the filter screen is in an "L" shape.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The pH meter installed in the water tank can be used to measure the pH value of the water in the water tank. The pH meter can convert the potential difference measured in the water tank into a current difference, and then connect the current in series with multiple electromagnets. When the current reaches the set value, the corresponding electromagnet can be energized to generate magnetism and start working. Then the magnetism generated by the electromagnet can adsorb the first sealing plate to a position close to the electromagnet. When the first sealing plate moves to a certain position, the discharge port can be opened to pour out acid and alkali solutions of different concentrations to neutralize the pH value in the water, thereby ensuring that the water mixed with cement will not be strongly acidic or alkaline. This setting is convenient for automatically adjusting the pH value in the water with high accuracy.

[0015] 2. Starting the driving motor can drive the connecting gear ring to rotate. During the rotation process, the connecting gear ring can drive multiple connecting gears that are meshed and connected internally to rotate synchronously. During the rotation of multiple connecting gears, the stirring rod and the stirring blades can be driven to rotate synchronously, thereby reducing the generation of stirring dead angles, improving the stirring effect and the mixing efficiency of the neutralization solution and water.

[0016] 3. When the second gear ring rotates to a certain position, the second gear ring can be meshed with the first driven gear and the second driven gear respectively, so that the second driven gear can drive the stirring rod and the stirring blade to rotate forward and reversely. The alternating forward and reverse rotation can make the neutralization solution and water be subjected to shear forces in different directions during the stirring process, which can promote the mixing and dispersion between water and the neutralization solution, thereby improving the stirring effect and uniformity.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-10 , the present invention provides a technical solution: comprising a mounting base 1, a mixer body 2 connected to the mounting base 1, and a feed frame 3 connected to the mixer body 2;

[0030] In the present invention, the mixer body 2 is used for concrete mixing as an example, and as necessary, it is of course equipped with a feeding mechanism, a discharging mechanism, a cleaning mechanism and other structures and equipment for concrete mixing, but since it is irrelevant to the technical problem to be solved by the present invention, it is not drawn;

[0031] Among them, please refer to Figures 3 to 5 The feed frame 3 is provided with a water quality regulating component 400, which includes a water storage tank 401 connected to the feed frame 3, a plurality of acid and alkali solution storage tanks 402 connected to the water storage tank 401, a potential current converter 403 connected to one side of the water storage tank 401, a pH meter 404 connected to the water storage tank 401, and an equal amount regulating component 500 which is synchronously adjusted with the pH meter 404 is also provided in the water storage tank 401;

[0032] The equal amount adjustment component 500 includes a connection frame 505 connected to the bottom of the acid-base solution storage box 402, a battery 501 is connected to the connection frame 505, and an electromagnet 502 is electrically connected to one side of the battery 501.

[0033] A compression spring 503 is connected to one side of the electromagnet 502, and the other end of the compression spring 503 is connected to a first blocking plate 504. The storage battery 501 is installed to be electrically connected to the potential current converter 403, and the starting currents of the multiple electromagnets 502 are different;

[0034] It should be noted that a feed pipe 12 is connected to the top of the acid-base solution storage box 402. The feed pipe 12 is funnel-shaped and a protective cover is hinged on the feed pipe 12. The feed pipe 12 is provided to facilitate adding new solution into the acid-base solution storage box 402. An observation window 13 is connected to the acid-base solution storage box 402. Scale lines are provided on the observation window 13 to facilitate observing the usage of the solution in the acid-base solution storage box 402.

[0035] It should be noted that the solutions stored in the multiple acid-base solution storage boxes 402 have different pH values, which makes it convenient to pour solutions of different pH values ​​according to the different pH values ​​measured in the water for accurate neutralization. The potential difference measured by the pH meter 404 can be converted into current by the potential-current converter 403 and transmitted to the electromagnet 502. The starting currents of the multiple electromagnets 502 are different. For example, when the pH value of the water is detected to be 3, the corresponding electromagnet 502 is powered on and started, and then the alkaline solution adapted to the pH concentration can be introduced into the water tank 401 for neutralization; in specific implementation, the pH meter 404 set in the water tank 401 can be used to measure the pH value of the water in the water tank 401, and the pH meter 404 can convert the potential difference measured in the water tank 401 into a current difference, and then the current is connected in series with the multiple electromagnets 502. When the current reaches the set value, the corresponding electromagnet 502 can be powered on to generate magnetism and start working, and then the magnetism generated by the electromagnet 502 can adsorb the first blocking plate 504. Move to a position close to the electromagnet 502. When the first sealing plate 504 moves to a certain position, the discharge port can be opened to pour out acid and alkali solutions of different concentrations to neutralize the pH value in the water, thereby ensuring that the water mixed with cement and the like will not be highly acidic or alkaline. This setting is convenient for automatically adjusting the pH value in the water with high accuracy.

[0036] Furthermore, in the process of adjusting the pH value, the solution may not have a significant impact on the pH value of the water during the initial addition process, but as the neutralization solution is continuously added, a small amount of neutralization solution may also affect the pH value of the water. Therefore, it is necessary to control the amount of pH value introduced so that the flow rate of the introduction is gradually reduced. For this purpose, please refer to Fig. 9 , and further includes a cut-off assembly 600 disposed at the bottom of the connection frame 505 for controlling the flow of the neutralization solution, wherein the cut-off assembly 600 includes a servo motor 601 connected to the connection frame 505,

[0037] The driving end of the servo motor 601 is connected to a transmission screw 602, a connecting nut 603 is threadedly connected to the transmission screw 602, and a second blocking plate 604 is connected to one side of the connecting nut 603;

[0038] It should be noted that the components in the interception assembly 600 and the equal amount adjustment assembly 500 are all arranged in the connection frame 505, and a partition is arranged in the connection frame 505 to separate the two components;

[0039] During the specific implementation, the servo motor 601 is started to rotate the transmission screw 602. During the rotation, the transmission screw 602 can drive the connecting nut 603 to move slowly, so that the second sealing plate 604 connected to one side of the connecting nut 603 also moves slowly synchronously. Even if the discharge diameter opened on the connecting frame 505 is gradually reduced, the flow rate of the neutralization solution is gradually reduced.

[0040] After the neutralization solution is added to the water storage tank 401, in order to facilitate the neutralization solution to be quickly mixed with water and thus neutralize the pH value in the water, it is necessary to further disclose the structure of the stirring component 900. Please continue to refer to Figures 4 to 7 , see Figure 2 , further comprising a stirring assembly 900 disposed in the water storage tank 401 for stirring water and the neutralization solution, wherein the stirring assembly 900 comprises a connecting gear ring 901 rotatably connected to the water storage tank 401, a driving motor 902 for driving the connecting gear ring 901 to rotate is connected to one side of the water storage tank 401, a plurality of connecting gears 904 are meshedly connected in the connecting gear ring 901, a mounting frame 903 is rotatably connected in the connecting gear ring 901, the connecting gear 904 is rotatably connected to the mounting frame 903, a stirring rod 905 is disposed on one side of the connecting gear 904, a plurality of stirring blades 906 are connected to the stirring rod 905, and an auxiliary assembly 1000 for further stirring the water and the neutralization solution is also disposed on one side of the connecting gear 904;

[0041] It should be noted that a plurality of turbulent holes are provided on the stirring blade 906; when the stirring blade 906 rotates, air flows between the stirring blade 906 and the turbulent holes to form an arc-shaped airflow, which gathers water and the neutralization solution to the center, thereby improving the stirring efficiency;

[0042] During specific implementation, starting the driving motor 902 can drive the connecting gear ring 901 to rotate. During the rotation process, the connecting gear ring 901 can drive the multiple connecting gears 904 that are meshed internally to rotate synchronously. During the rotation process of the multiple connecting gears 904, the stirring rod 905 and the stirring blade 906 can be driven to rotate synchronously, thereby reducing the generation of stirring dead angles, improving the stirring effect and the mixing efficiency of the neutralization solution and water.

[0043] Specifically, to further improve the efficiency of mixing, please continue to refer to Figure 8 The auxiliary component 1000 includes a second gear ring 1001 connected to the connecting gear 904, a first driven gear 1002 is connected to the second gear ring 1001, a second driven gear 1003 is rotatably connected to the second gear ring 1001, and the second driven gear 1003 is meshed with the second gear ring 1001 and the first driven gear 1002 respectively;

[0044] It should be noted that the inner teeth of the second gear ring 1001 and the first driven gear 1002 each account for half of their circumferences, forming a half gear ring and a half gear. When the second driven gear 1003 is meshed with the second gear ring 1001, the second driven gear 1003 can rotate counterclockwise. When the second driven gear 1003 is meshed with the first driven gear 1002, The second driven gear 1003 rotates clockwise, so that the second driven gear 1003 can perform forward and reverse rotation effects; in specific implementation, when the second gear ring 1001 rotates, the first driven gear 1002 rotates synchronously, and then when the second gear ring 1001 rotates to a certain position, the second gear ring 1001 can be meshed with the first driven gear 1002 and the second driven gear 1003 respectively, so that the second driven gear 1003 can drive the stirring rod 905 and the stirring blade 906 to rotate forward and reverse, and the alternating forward and reverse rotation can make the neutralization solution and water subject to shear forces in different directions during the stirring process, which can promote the mixing and dispersion between water and the neutralization solution, thereby improving the stirring effect and uniformity. Secondly, the forward and reverse rotating stirring rod 905 and stirring blade 906 can be used in conjunction with the stirring in the stirring component 900 to further reduce dead angles in the stirring process, ensure the comprehensive fusion of the neutralization solution and water, and further improve the neutralization efficiency of water and pH value.

[0045] Further, to improve the sliding stability of the first blocking plate 504, please refer to Fig.10 The first blocking plate 504 is connected to two mutually symmetrical guide blocks 7, and the other side of the guide block 7 is slidably connected in the connection frame 505, and a slide groove for the guide block 7 to slide is provided in the connection frame 505;

[0046] During specific implementation, the provided guide block 7 can limit and guide the sliding of the first blocking plate 504, further improving the stability of the first blocking plate 504 during the sliding process.

[0047] For further information, please continue to refer to Fig. 9 , a guide rod 8 is connected in the connecting frame 505, a connecting nut 603 is slidably connected to the guide rod 8, and a sliding opening for the guide rod 8 to slide is provided on the connecting nut 603;

[0048] During specific implementation, the guide rod 8 can limit and guide the movement of the connecting nut 603, thereby preventing the connecting nut 603 from rotating along with the transmission screw 602, and further improving the stability of the movement of the connecting nut 603.

[0049] Further, to prevent impurities in the water from entering the water storage tank 401, please refer to Figure 4 The feed inlet of the mounting base 1 is detachably connected with a filter screen 11 by screws, and the filter screen 11 is in an "L" shape;

[0050] In a specific implementation, the filter 11 can filter impurities in the water. As the use time increases and more impurities are left on the filter 11, the filter 11 can be removed for cleaning.

[0051] Working principle: When the pH value of water needs to be adjusted: the pH meter 404 set in the water tank 401 can be used to measure the pH value of the water in the water tank 401, and the pH meter 404 can convert the potential difference measured by the water tank 401 into a current difference, and then connect this current in series with multiple electromagnets 502. When the current reaches the set value, the corresponding electromagnet 502 can be energized to generate magnetism and start working. Then the magnetism generated by the electromagnet 502 can adsorb the first blocking plate 504 to move to a position close to the electromagnet 502. When the first blocking plate 504 moves to a certain position, the discharge port can be opened, and acid and alkali solutions of different concentrations are poured out to neutralize the pH value in the water, thereby ensuring that the water mixed with cement and the like will not be strongly acidic or alkaline. This setting is convenient for automatically adjusting the pH value in the water, and has high accuracy.

[0052] Starting the driving motor 902 can drive the connecting gear ring 901 to rotate. During the rotation of the connecting gear ring 901, the connecting gear ring 901 can drive the multiple connecting gears 904 meshingly connected therein to rotate synchronously. During the rotation of the multiple connecting gears 904, the stirring rod 905 and the stirring blade 906 can be driven to rotate synchronously, thereby reducing the generation of stirring dead angles, improving the stirring effect and the mixing efficiency of the neutralization solution and water;

[0053] When the second gear ring 1001 rotates, the first driven gear 1002 rotates synchronously. Then, when the second gear ring 1001 rotates to a certain position, the second gear ring 1001 can be meshed with the first driven gear 1002 and the second driven gear 1003 respectively, so that the second driven gear 1003 can drive the stirring rod 905 and the stirring blade 906 to rotate forward and reversely. The alternating forward and reverse rotation can make the neutralization solution and water receive shear forces in different directions during the stirring process, which can promote the mixing and dispersion between water and the neutralization solution, thereby improving the stirring effect and uniformity. Secondly, the forward and reverse rotating stirring rod 905 and stirring blade 906 can be used in conjunction with the stirring in the stirring component 900 to further reduce the dead angle in the stirring process, ensure the comprehensive fusion of the neutralization solution and water, and further improve the neutralization efficiency of water and pH value.
