Technical Field
[0001] This utility model relates to the field of concrete production technology, and in particular to a timed water supply structure for commercial concrete mixing plants. Background Technology
[0002] Concrete is made by mixing cementitious materials, granular aggregates, water, and, if necessary, admixtures and additives in a certain proportion. Water plays a key role in concrete, and the amount of water added directly affects the quality of the concrete. If too much water is added, it will lead to reduced strength and poor durability of the concrete, and may also cause bleeding and segregation. If too little water is added, the workability of the concrete will be poor, making it difficult to mix evenly, affecting its construction performance, and will also reduce the density and strength of the concrete.
[0003] Concrete is generally mixed using a mixer. When mixing concrete, water needs to be added to the mixer at regular intervals to ensure the mixing effect. However, when using the mixer, it is dangerous for personnel to manually add water due to the internal mechanical rotation. At the same time, it is necessary to add water at regular intervals, which may cause fatigue among personnel and reduce efficiency. Therefore, it is necessary to propose a timed water adding device for concrete mixing.
[0004] An existing patent (publication number: CN219486161U) describes a timed water-adding device for concrete mixing. Water is poured into a water tank through an inlet pipe. A hydraulic rod is activated to push an mounting plate to rotate upwards, lifting the drain pipe and allowing concrete to be poured into a mixing drum. A drive motor is activated to rotate a rotating rod and a mixing rod, which mixes the concrete. A timer controller keeps track of the time. When the time is up, the timer controller activates the hydraulic rod to rotate the mounting plate and drain pipe downwards, allowing water to be poured into the mixing drum through the drain pipe. This device allows for timed water addition to the mixing drum, eliminating the need for manual water addition while the mixing drum is in operation and thus increasing mixing efficiency.
[0005] To address the aforementioned issues, existing patents offer solutions. Existing timed water addition structures in commercial concrete mixing plants often rely on manual operation or simple timing devices, which are not conducive to automated water addition. This results in high labor intensity and low production efficiency for workers. Furthermore, it is difficult to clean the material adhering to the inner wall of the mixing drum, leading to material residue and affecting the uniformity of mixing.
[0006] Therefore, a timed water supply structure for commercial concrete mixing plants is proposed. Utility Model Content

[0027] 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.
[0028] Please see Figure 1-6 The present invention provides the following technical solution:
[0029] A timed water supply structure for a commercial concrete mixing plant includes a base 1, a mixing drum 2 fixedly connected to the top of the base 1, a mixing component 5 disposed inside the mixing drum 2, a top seat 3 fixedly connected to the top of the mixing drum 2, and a water supply component 4 disposed on the top of the top seat 3.
[0030] The water filling assembly 4 includes a water storage tank 401 fixedly connected to the front side of the base 1. A control panel 402 is provided on the outside of the water storage tank 401. A time relay 403 is electrically connected to the top of the control panel 402. A water pipe 404 is connected to the right side of the water storage tank 401. An electromagnetic control valve 405 is provided on the outside of the water pipe 404. A delivery pump 406 is provided on the right side of the water storage tank 401. The inlet end of the delivery pump 406 is connected to the water pipe 404. The output end of the delivery pump 406 is connected to a delivery pipe 407. A connecting pipe 408 is connected to the outside of the delivery pipe 407. A nozzle 409 is connected to the bottom of the connecting pipe 408. The nozzle 409 is bolted to the top seat 3.
[0031] In this embodiment: the timing parameters of the time relay 403 are set through the control panel 402. When the time set by the time relay 403 is reached, the time relay 403 sends a signal to the solenoid control valve 405 and the delivery pump 406 through the control panel 402. Then, the solenoid control valve 405 opens immediately after receiving the signal, and then the delivery pump 406 is started. Then, the water in the water storage tank 401 flows into the delivery pump 406 through the water pipe 404 under the suction of the delivery pump 406. Then, the delivery pump 406 pressurizes the inflowing water to give the water sufficient pressure energy. The pressurized water flows along the delivery pipe 407 and then enters the connecting pipe 408. Finally, it is evenly sprayed into the mixing drum 2 from the nozzle 409 in the form of water flow. As the mixing continues, the time relay 403 will repeat the above water addition process at the set time interval to ensure that the water can be fully mixed with other raw materials in a predetermined rhythm and proportion during the mixing process.
[0032] Specifically, such as Figure 3As shown, the stirring assembly 5 includes a drive motor 501 fixedly connected to the left side of the base 1. The output end of the drive motor 501 is movably connected to a transmission belt 502, and the inner side of the transmission belt 502 is movably connected to a stirring rod 503.
[0033] Specifically, such as Figure 3 As shown, a fixed base 504 is fixedly connected to the outer side of the stirring rod 503, a compression spring 505 is fixedly connected inside the fixed base 504, a scraper 506 is fixedly connected to the outer side of the compression spring 505, and a stirring blade 507 is fixedly connected to the outer side of the stirring rod 503.
[0034] Specifically, such as Figure 3 As shown, an arc-shaped baffle 508 is fixedly connected to the top of the stirring drum 2, and the arc-shaped baffle 508 is located on top of the stirring blade 507.
[0035] In this embodiment: By starting the drive motor 501, when the output shaft of the drive motor 501 rotates, it drives the transmission belt 502 to perform a circular motion. During the motion, the transmission belt 502 smoothly transmits the rotational power of the drive motor 501 to the mixing rod 503 through the friction between itself, the output end of the drive motor 501, and the mixing rod 503. As the mixing rod 503 rotates, the mixing blades 507 rotate accordingly, stirring the concrete material in the mixing drum 2. The shape and position design of the mixing blades 507 enable them to stir the material in different directions when the mixing rod 503 rotates. The force is applied to cause the material to tumble and mix up and down and left and right, achieving a uniform mixing effect. At the same time, the scraper 506 connected to the compression spring 505 inside the fixed seat 504 on the mixing rod 503 will move closely against the inner wall of the mixing drum 2 during the mixing process, scraping off the material adhering to the inner wall to prevent material residue and further improve the uniformity of mixing. During the mixing process, its arc-shaped baffle 508 blocks the splashed concrete material, and its arc-shaped baffle 508 uses its bottom to bend in an arc shape, allowing the material adhering to the bottom to slide down its arc-shaped inclined surface, preventing the material from splashing out of the mixing drum 2 and reducing material loss.
[0036] Specifically, such as Figure 5 As shown, the top seat 3 is internally connected to an inclined plate 6, the inclined plate 6 is externally connected to a mounting base 7, and the mounting base 7 is internally connected to a torsion spring 8.
[0037] Specifically, such as Figure 6 As shown, a fixing plate 9 is fixedly connected to the right side of the water storage tank 401. The fixing plate 9 is located at the bottom of the delivery pump 406, and a buffer pad 10 is snapped onto the top of the fixing plate 9.
[0038] In this embodiment: by setting the inclined plate 6, the fixed seat 504 and the torsion spring 8, when the nozzle 409 sprays water into the mixing drum 2, the inclined plate 6 will guide the water flow to be more evenly distributed at the bottom of the mixing drum 2, so as to improve the mixing effect of water and materials and ensure the quality of concrete mixing. At the same time, the inclined plate 6 can also block the concrete material splashing from below the mixing blade 507, preventing the material from splashing out of the mixing drum 2, reducing material loss and keeping the working environment clean. By setting the fixed plate 9 and the buffer pad 10, the buffer pad 10 can effectively reduce the vibration generated by the delivery pump 406 during operation and transmit it to the water storage tank 401, avoiding the loosening and damage of parts due to long-term vibration, and extending the service life of the equipment. At the same time, the fixed plate 9 provides stable support for the delivery pump 406, and together with the buffer pad 10, it ensures the stable operation of the delivery pump 406, ensures the reliability of the water addition process, and thus improves the quality of concrete.
[0039] Specifically, such as Figure 6 As shown, an auxiliary rubber seat 11 is fixedly connected to the right side of the water storage tank 401, and the auxiliary rubber seat 11 is snapped into the water pipe 404.
[0040] Specifically, such as Figure 6 As shown, a water inlet pipe 12 is connected to the left side of the water storage tank 401, and an ultrasonic level gauge 13 is installed on the top of the water storage tank 401.
[0041] In this embodiment: By setting an auxiliary rubber seat 11, the water pipe 404 can be protected from damage caused by external impact or friction, avoiding water leakage and ensuring smooth water addition. By setting an inlet pipe 12 and an ultrasonic level gauge 13, water is injected into the water storage tank 401 through the inlet pipe 12 to replenish the water required for mixing. At the same time, the ultrasonic level gauge 13 continuously emits and receives ultrasonic waves, calculates the distance to the water surface based on the ultrasonic wave reflection time, and monitors the water level in the tank in real time, feeding back the data. The operator can add water in time through the inlet pipe 12 when the water level is low, based on the water level data. The inlet pipe 12 ensures a continuous water supply to the water storage tank 401, reducing concrete quality problems caused by improper water addition.
[0042] Working Principle: In the process of using the timed water-addition structure in a commercial concrete mixing plant, water is first added to the storage tank 401 through the inlet pipe 12. The ultrasonic level gauge 13 continuously emits and receives ultrasonic waves to monitor the water level in the tank in real time, allowing operators to monitor water volume and replenish the water supply promptly. Next, the operator sets the timing parameters of the time relay 403 on the control panel 402 according to the concrete mixing requirements. Then, concrete material is added to the mixing drum 2. The drive motor 501 is then started. When the output shaft of the drive motor 501 rotates, it drives the transmission belt 502 in a circular motion. During this motion, the transmission belt 502 relies on the distance between itself and the output end of the drive motor 501 and the mixing rod 503. Friction smoothly transmits the rotational power of the drive motor 501 to the stirring rod 503. As the stirring rod 503 rotates, the stirring blades 507 rotate accordingly, stirring the concrete material inside the mixing drum 2. The shape and position design of the stirring blades 507 allow them to exert forces on the material in different directions when the stirring rod 503 rotates, causing the material to tumble and mix up and down and left and right, achieving a uniform mixing effect. At the same time, the scraper 506 connected to the compression spring 505 inside the fixed seat 504 on the stirring rod 503 moves closely against the inner wall of the mixing drum 2 during the mixing process, scraping off the material adhering to the inner wall to prevent material residue and further improve the uniformity of mixing. During the mixing process, the arc-shaped baffle 508 and the inclined plate 6 move from both the top and bottom directions. To prevent splashed concrete material from entering the mixing drum 2, the inclined plate 6 uses its own inclination to generate gravity, causing the material adhering to the bottom to slide back down the inclined surface. When the inclined plate 6 tilts excessively, its torsion spring 8 will drive the inclined plate 6 to return to its original position. At the same time, its arc-shaped baffle 508 bends in an arc shape, causing the material adhering to the bottom to slide down its arc-shaped inclined surface, preventing material from splashing out of the mixing drum 2 and reducing material loss. When the time set by the time relay 403 is reached, the time relay 403 will send a signal to the solenoid control valve 405 and the delivery pump 406 through the control panel 402. Then, the solenoid control valve 405 will open immediately after receiving the signal, and then the delivery pump 406 will start. Then, the water in the water storage tank 401 will be drawn by the delivery pump 406. Under the action of force, water flows into the delivery pump 406 through the water pipe 404. Then, the delivery pump 406 pressurizes the incoming water to give it sufficient pressure energy. The pressurized water flows along the delivery pipe 407 and then enters the connecting pipe 408. Finally, it is evenly sprayed into the mixing drum 2 from the nozzle 409 in a water flow pattern. During the water spraying process, the inclined plate 6 and the arc-shaped baffle 508 in the top seat 3 guide the water flow to enter the mixing drum 2 more evenly, so as to improve the mixing effect of water and materials and further ensure the quality of concrete mixing. As the mixing continues, the time relay 403 will repeat the above water addition process at the set time interval to ensure that the water can be fully mixed with other raw materials in a predetermined rhythm and proportion during the mixing process.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
