Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and in particular to a cleaning structure for a mixing tank in commercial concrete production. Background Technology

[0002] In the production of ready-mixed concrete, the mixing tank is the core equipment. Concrete slurry is easily left on its inner wall and the surface of the mixing components. If it is not cleaned in time, the residual concrete will gradually harden and clump together. This will not only affect the accuracy of the subsequent concrete mix proportions and the uniformity of the mixing, but also increase the operating resistance of the equipment, aggravate the wear of the mixing blades, tank walls and other components, shorten the service life of the equipment, and may even lead to a decline in the quality of the concrete product due to the detachment of residual clumps.

[0003] Currently, the cleaning methods for commercial concrete mixing tanks are mainly divided into two categories: manual cleaning and simple mechanical cleaning. Manual cleaning requires operators to enter the tank or manually clean it using long-handled tools. This is labor-intensive, inefficient, and poses safety hazards such as working at heights and in the confined space inside the tank. It is also difficult to thoroughly remove residues from dead corners inside the tank. Simple mechanical cleaning devices are mostly fixed spray systems. Although they can replace some manual operations, the positions of the cleaning components are fixed, making it difficult to adapt to mixing tanks of different diameters and depths, resulting in poor versatility. Secondly, they lack flexible adjustment mechanisms, making it impossible to achieve all-round coverage cleaning, thus affecting the cleaning effect.

[0004] Therefore, a cleaning structure for commercial concrete mixing tanks is proposed. Utility Model Content

At the same time, it is difficult to thoroughly remove residues from dead corners inside the tank. Simple mechanical cleaning devices are mostly fixed spray systems. Although they can replace some manual operations, the positions of the cleaning components are fixed, making it difficult to adapt to mixing tanks of different diameters and depths, resulting in poor versatility. Secondly, they lack flexible adjustment mechanisms and cannot achieve all-round coverage cleaning, thus affecting the cleaning effect.

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A cleaning structure for a commercial concrete mixing tank includes a support 1 and a mixing tank body 2. A lifting frame 3 is fixedly connected to the top of the inner wall of the support 1. An adjustment component 4 is provided inside the lifting frame 3. A cleaning component 5 is provided at the bottom of the adjustment component 4. The cleaning component 5 includes a mounting frame 501. A vertical pipe 502 is fixedly connected inside the mounting frame 501. Multiple nozzles 503 are fixedly connected to both sides of the surface of the vertical pipe 502. A hose 504 is fixedly connected to the rear side of the surface of the vertical pipe 502. A high-pressure water pump 505 is fixedly connected to the top left side of the support 1. A rotary joint 506 is provided at the outlet end of the high-pressure water pump 505. The hose 504 is fixedly connected to the rotating end of the rotary joint 506. An extension pipe 507 is fixedly connected to the suction end of the high-pressure water pump 505 and is connected to an external water storage device. Scrapers 508 are bolted to the front and rear sides of the mounting frame 501. The scrapers 508 are in contact with the inner wall of the mixing tank body 2.

[0026] In this embodiment: by setting up the cleaning component 5, the mounting frame 501 serves as the basic frame of the cleaning component 5, integrating components such as the vertical pipe 502 and the scraper 508 into a whole, ensuring stable operation of each component during the cleaning process, and providing an installation benchmark for each component to ensure accurate relative positions. The vertical pipe 502 is a key channel for water flow, connecting the hose 504 to the nozzle 503, guiding the water delivered by the high-pressure water pump 505 to each nozzle 503. Its vertical arrangement allows the water flow to be more evenly distributed to nozzles 503 at different heights, ensuring thorough cleaning of the inner wall of the mixing tank body 2. The high-pressure water jet from the vertical pipe 502 is converted into a powerful jet and sprayed onto the inner wall of the mixing tank body 2. Multiple jets 503 distributed on both sides of the vertical pipe 502 allow for rinsing of the inner wall of the mixing tank body 2 at different angles and positions. Combined with the rotation and lifting motion of the cleaning assembly 5, it can thoroughly remove residual concrete laitance and fine particles from the inner wall of the mixing tank body 2. The hose 504 connects the vertical pipe 502 to the rotary joint 506. Because the cleaning assembly 5 needs to rotate, the hose 504 possesses a certain degree of flexibility to adapt to the rotation of the cleaning assembly. The rotation and bending of component 5 ensures continuous unobstructed water flow during rotation. High-pressure water pump 505 provides power for the cleaning process, drawing water from an external water storage device through its suction end and pressurizing it to achieve sufficient pressure. After being sprayed through the delivery pipeline and nozzle 503, it effectively impacts residual concrete on the inner wall of the mixing tank body 2, enhancing the rinsing effect. Rotary joint 506 is installed between the outlet end of high-pressure water pump 505 and hose 504. Its fixed end connects to high-pressure water pump 505, and its rotating end connects to hose 504, enabling stable water delivery during rotation and solving the problem of... To address the issue of pipe entanglement during the rotation of the cleaning component 5, a continuous and stable flow of high-pressure water is ensured into the vertical pipe 502 and nozzle 503. The extension pipe 507 serves as a water intake channel, allowing external water to be introduced into the high-pressure water pump 505, providing a continuous water supply for the entire cleaning component 5. During the rotation and lifting of the cleaning component 5, the scraper 508 can directly scrape off the thicker and more stubborn concrete residue clumps adhering to the inner wall of the mixing tank body 2. This works in conjunction with the high-pressure water flow from the nozzle 503, first removing the thick layer of residue through the scraper 508, and then washing away the remaining debris with the water flow, significantly improving cleaning efficiency and cleanliness.

[0027] Specifically, such as Figure 4 As shown, the adjustment component 4 includes a fixed circular block 401, a drive motor 402 is fixedly connected to the top of the fixed circular block 401, and the output shaft of the drive motor 402 passes through the fixed circular block 401 and is fixedly connected to a rotating circular block 403.

[0028] Specifically, such as Figure 4As shown, an electric push rod 404 is fixedly connected to the outer side of the rotating block 403, and a connecting rod 405 is fixedly connected to the telescopic end of the electric push rod 404. The bottom of the connecting rod 405 is fixedly connected to the top of the mounting frame 501.

[0029] Specifically, such as Figure 2 As shown, both sides of the inner wall of the lifting frame 3 are provided with moving grooves 6. The inside of the right moving groove 6 is rotatably connected to a lead screw 7 through a bearing, and the inside of the left moving groove 6 is fixedly connected to a limit rod 8.

[0030] Specifically, such as Figure 2 As shown, the surface of the lead screw 7 is threaded with an internal thread block 9, the surface of the limiting rod 8 is slidably connected with a limiting block 10, a lifting plate 11 is fixedly connected between the internal thread block 9 and the limiting block 10 on opposite sides, a U-shaped connecting frame 12 is fixedly connected to the bottom of the lifting plate 11, the bottom of the U-shaped connecting frame 12 is fixedly connected to the top of the fixed round block 401, and the drive motor 402 is located inside the U-shaped connecting frame 12.

[0031] Specifically, such as Figure 2 As shown, a servo motor 13 is fixedly connected to the top of the lead screw 7, and the servo motor 13 is fixedly connected to the top of the lifting frame 3.

[0032] In this embodiment: By setting the adjustment component 4, the fixed circular block 401 provides a mounting point for the drive motor 402, ensuring that the drive motor 402 can operate stably. The output shaft of the drive motor 402 can drive the rotating circular block 403 to rotate, thereby causing the scraper 508 and the nozzle 503 below to perform a 360-degree circular motion with the rotating circular block 403, achieving annular coverage cleaning of the inner wall of the mixing tank body 2, eliminating blind spots in local cleaning. The rotating circular block 403 is used to connect the drive motor 402 and the electric push rod 404. On the one hand, it can transmit the rotational power of the drive motor 402, and on the other hand, it can provide an installation reference for the electric push rod 404, ensuring that the electric push rod 404 can rotate synchronously with the rotating circular block 403, so that the cleaning component 5 can still flexibly adjust its radial position during rotation. The electric push rod 404 can change the extension length of the connecting rod 405 through telescopic movement, thereby ensuring that the cleaning component 5 can always maintain an appropriate distance from the inner wall of the mixing tank body 2, thus adapting to mixing tanks of different sizes. The main body 2 and the moving groove 6 provide installation space and motion guidance for the lead screw 7 and the limiting rod 8, restricting the movement trajectory of the internal thread block 9 and the limiting block 10, ensuring that the lifting plate 11 can only move stably in the vertical direction. The lead screw 7 can rotate under the drive of the servo motor 13. Through the threaded engagement with the internal thread block 9, the rotational motion can be converted into the vertical lifting motion of the internal thread block 9, thereby driving the lifting plate 11 and the cleaning component 5 below to lift synchronously, realizing the cleaning of different depth areas of the mixing tank body 2. The U-shaped connecting frame 12 can connect the lifting plate 11 and the fixed round block 401, so that the lifting plate 11 can drive the fixed round block 401 and other components to lift. At the same time, its U-shaped design can provide a space for the drive motor 402. The servo motor 13 can provide power for the rotation of the lead screw 7. By precisely controlling the speed and direction of rotation of the servo motor 13, the precise lifting of the cleaning component 5 can be achieved. The cleaning stroke can be set according to the depth of the mixing tank body 2, thereby meeting different cleaning needs.

[0033] Specifically, such as Figure 4 As shown, a laser profile sensor 14 is fixedly installed in the middle of the bottom of the rotating block 403, and a controller 15 is fixedly installed on the outside of the bracket 1. The laser profile sensor 14 and the controller 15 are electrically connected.

[0034] Specifically, such as Figure 1 As shown, each of the four corners of the bottom of the bracket 1 is equipped with a universal self-locking wheel 16.

[0035] In this embodiment: With the above settings, the laser contour sensor 14 is installed at the bottom of the rotating block 403, which can scan the contour of the inner wall of the mixing tank body 2 in real time and obtain distance data. The signal is transmitted to the controller 15 to ensure that the output shaft of the drive motor 402 can be coaxial with the central axis of the mixing tank body 2, providing a basis for the action of the electric push rod 404 and the drive motor 402. The controller 15 can receive the detection data from the laser contour sensor 14, calculate the optimal position and motion parameters of the cleaning component 5 according to the preset program, and automatically control the drive motor 402, electric push rod 404, servo motor 13 and other components to work together, realize intelligent adjustment of the cleaning process, improve adaptability and cleaning accuracy. By setting the universal self-locking wheel 16, the universal self-locking wheel 16 can easily drive the entire cleaning structure to move flexibly. At the same time, it has a self-locking function, thereby further improving the stability of use.

[0036] Working principle: First, the entire cleaning structure is moved to the side of the mixing tank body 2 to be cleaned by moving the support bracket 1. The position is adjusted so that the support bracket 1 is roughly aligned with the tank opening. The universal self-locking wheel 16 is locked to ensure the stability of the equipment. Then, the extension pipe 507 is connected to the external water storage device to ensure sufficient water supply. After that, the laser contour sensor 14 scans the contour of the inner wall of the mixing tank body 2, fits the position of the tank's central axis, and transmits the data to the controller 15. It is ensured that the output shaft of the drive motor 402 is coaxial with the tank's central axis. Then, the controller 15 starts the servo motor 13, which drives the lead screw 7 to rotate, so that the internal thread block 9 rises or falls along the lead screw 7. This drives the lifting plate 11, the U-shaped connecting frame 12, and the adjustment component 4 and cleaning component 5 below to rise and fall synchronously until the cleaning component 5 is lowered to a suitable height inside the mixing tank body 2. Then, the controller 15 starts the electric push rod 404, so that the electric push rod 404 drives the... The scraper 508 moves towards the inner wall of the mixing tank body 2 until it is in close contact with the interior. Then, the high-pressure water pump 505 is started, and the cleaning water enters the vertical pipe 502 through the extension pipe 507, rotary joint 506, and hose 504. It is then sprayed out at high speed from the nozzle 503, impacting the inner wall of the mixing tank body 2. The drive motor 402 drives the rotating block 403 to rotate, making the cleaning component 5 move in a circular motion. The nozzle 503 can then perform a 360-degree circular rinse on the inner wall of the mixing tank body 2. At the same time, the scrapers 508 on the front and rear sides of the mounting frame 501 scrape away stubborn concrete clumps on the inner wall of the mixing tank body 2 as they rotate. This, combined with the high-pressure water flow, improves the cleaning effect. Then, the servo motor 13 is periodically rotated forward and backward, driving the lead screw 7 to move the cleaning component 5 up and down, thus achieving comprehensive cleaning of different height areas inside the mixing tank body 2.

[0037] 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.
