Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, specifically to a commercial concrete mixing tank structure with a rapid descaling mechanism. Background Technology

[0002] Commercial concrete, also known as ready-mixed concrete, refers to ready-mixed concrete produced by mixing cement, sand, gravel, water, admixtures, and additives in a specific ratio at a batching plant. It is then transported by mixer trucks to the intended location within a specified timeframe. It boasts advantages such as stable quality, high production efficiency, energy conservation, and environmental friendliness, and is widely used in various civil engineering projects, including buildings, roads, and bridges. The mix proportions are determined based on design requirements, and raw materials are precisely measured using precise metering equipment. The commercial concrete processing involves determining the mix proportions according to design requirements, followed by mixing the materials in a mixer.

[0003] A search revealed that Chinese Patent Publication No. CN207578709U discloses a residual material cleaning device for a ready-mixed concrete mixing tank. The device includes a mixing tank body, a drive motor mounted above the tank body, and a motor shaft extending vertically downwards into the mixing tank body. Agitator blades are mounted on the motor shaft within the mixing tank body, and scraper plates are mounted on the agitator blades. This structure effectively solves the problem of cleaning residual concrete from the inner wall of the mixing tank during ready-mixed concrete processing, significantly reducing concrete residue and extending the working cycle of the mixing tank after each residual concrete cleaning.

[0004] However, this device also has the following drawbacks:

[0005] When the concrete residue on the inner wall of the mixing tank is thick and hard, and adheres tightly to the inner wall, it may be difficult to wash it off with water. The concrete residue may also damage the scraper of the device. This device does not solve this problem. Utility Model Content

[0006] The purpose of this invention is to provide a commercial concrete mixing tank structure with a rapid descaling mechanism. By setting multiple sets of ultrasonic transducer bodies, the mixing tank body will generate high-frequency vibration. The vibration will weaken the adhesion between concrete residue and the inner wall of the tank, making it easier for the residue to fall off the tank wall and achieve the purpose of descaling. Furthermore, by setting a movable component, it is convenient to descale different positions of the mixing tank body, thereby improving the descaling effect and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A commercial concrete mixing tank structure with a rapid descaling mechanism includes a mixing tank body, wherein a fixed top ring and a fixed bottom ring are fixedly installed at the top and bottom of the mixing tank body, respectively.

[0009] It also includes a moving component, which includes a moving ring that slides against the outer side wall of the mixing tank body. A moving seat is fixedly installed on one side of the moving ring and is mounted on the surface of the lead screw.

[0010] It also includes a cleaning assembly, which includes multiple sets of ultrasonic transducer bodies. The output end of the ultrasonic transducer body abuts against the outer wall of the mixing tank body. The ultrasonic transducer body is slidably installed inside the mounting base. The top of the mounting base is fixedly connected to a fixed base. The fixed base is distributed around the moving ring and is fixedly connected to the moving ring.

[0011] Preferably, the top of the lead screw is rotatably mounted on a fixed top ring, and the bottom of the lead screw is rotatably mounted on a fixed bottom ring.

[0012] Preferably, the bottom of the lead screw is connected to the output end of the motor, and the motor is fixedly installed on the bottom of the fixed bottom ring.

[0013] Preferably, slide blocks are fixedly installed on the other two sides of the movable ring and on the side opposite to the movable seat. The slide blocks are slidably installed on the surface of the guide rod. The top and bottom of the guide rod are fixedly installed on the fixed top ring and the fixed bottom ring, respectively.

[0014] Preferably, the mounting base is provided with a spring inside, and the spring is in sliding clearance fit with the inner wall of the mounting base.

[0015] Preferably, one end of the spring abuts against one side of the ultrasonic transducer body, and the other end of the spring abuts against the adjustment plate.

[0016] Preferably, the adjusting plate is slidably fitted inside the mounting base, one side of the adjusting plate is rotatably connected to the adjusting screw, and the adjusting screw is threadedly fitted to the mounting base.

[0017] Preferably, the inner wall of the mounting base is provided with a limiting groove, and a limiting block is slidably installed inside the limiting groove. The limiting block is fixedly installed on the top side of the ultrasonic transducer body.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model features multiple sets of ultrasonic transducer bodies, resulting in a simple and convenient structure. These transducers generate high-frequency vibrations in the mixing tank, weakening the adhesion between concrete residue and the inner wall of the tank. This makes the residue easier to detach from the tank wall, achieving descaling. The inclusion of a movable component allows for descaling at different locations within the mixing tank, improving the descaling effect. Furthermore, placing the movable and cleaning components on the exterior of the mixing tank extends their service life and avoids interfering with the normal operation of the internal mixing components.

[0024] 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.

[0025] Please see Figures 1-3 This utility model provides a technical solution:

[0026] A commercial concrete mixing tank structure with a rapid descaling mechanism includes a mixing tank body 1. A fixed top ring 2 and a fixed bottom ring 3 are fixedly installed on the top and bottom of the mixing tank body 1, respectively. The mixing tank body 1 also includes a moving component, which includes a moving ring 4. The moving ring 4 is slidably engaged with the outer side wall of the mixing tank body 1. A moving seat 5 is fixedly installed on one side of the moving ring 4. The moving seat 5 is mounted on the surface of a lead screw 6. The top of the lead screw 6 is rotatably mounted on the fixed top ring 2, and the bottom of the lead screw 6 is rotatably mounted on the fixed bottom ring 3. The bottom of the lead screw 6 is connected to the output end of a motor 10. The motor 10 is fixedly installed on the bottom of the fixed bottom ring 3. Slide seats 11 are fixedly installed on the other two sides of the moving ring 4 and on the side opposite to the moving seat 5. The slide seats 11 are slidably mounted on the surface of a guide rod 12. The top and bottom of the guide rod 12 are fixedly installed on the fixed top ring 2 and the fixed bottom ring 3, respectively.

[0027] By setting up a motor 10, the output end of the motor 10 can drive the lead screw 6 to rotate. The rotating lead screw 6 can drive the moving seat 5 to move up and down, thereby driving the moving ring 4 to move up and down. This makes it easy to move the cleaning component to different positions on the outer surface of the mixing tank body 1, thus making it easy to clean the residue in different positions inside the mixing tank body 1. By setting up a guide rod 12 to work with the slide 11, the stability of the moving ring 4 during movement can be improved.

[0028] It also includes a cleaning component, which includes multiple ultrasonic transducer bodies 7. The output end of the ultrasonic transducer body 7 abuts against the outer wall of the mixing tank body 1. The ultrasonic transducer body 7 is slidably installed inside the mounting base 8. The top of the mounting base 8 is fixedly connected to the fixed base 9. The fixed base 9 is distributed around the moving ring 4 and is fixedly connected to the moving ring 4.

[0029] By setting up multiple sets of ultrasonic transducer bodies 7, which are electrically connected to an external ultrasonic generator, the ultrasonic transducer bodies 7 convert electrical energy into high-frequency vibrational mechanical energy. When the output end of the ultrasonic transducer body 7 contacts the outer wall of the mixing tank body 1, it causes the mixing tank body 1 to generate high-frequency vibration. This vibration propagates in the tank material of the mixing tank body 1 in the form of elastic waves. When the elastic waves propagate to the interface between the inner wall of the mixing tank body 1 and the concrete residue, due to the different acoustic properties of the two materials, the elastic waves will produce complex reflection, refraction, and scattering phenomena at the interface. Under these effects, alternating stress and strain will be generated inside the concrete residue. When the stress exceeds the strength limit of the concrete, the concrete will gradually crack and break. At the same time, the vibration will also weaken the adhesion between the concrete residue and the inner wall of the mixing tank body 1, thereby causing the residue to fall off the tank wall and achieving the purpose of descaling.

[0030] A spring 13 is installed inside the mounting base 8. The spring 13 slides and is fitted with the inner wall of the mounting base 8. One end of the spring 13 abuts against one side of the ultrasonic transducer body 7, and the other end of the spring 13 abuts against the adjusting plate 14. The adjusting plate 14 slides and is fitted with the inside of the mounting base 8. One side of the adjusting plate 14 is rotatably connected to the adjusting screw 15. The adjusting screw 15 is threaded and fitted with the mounting base 8. A limit groove 16 is opened on the inner wall of the mounting base 8. A limit block 17 is slidably installed inside the limit groove 16. The limit block 17 is fixedly installed on the top side of the ultrasonic transducer body 7.

[0031] By setting the adjusting screw 15, the position of the adjusting plate 14 can be adjusted by rotating the adjusting screw 15, thereby compressing the spring 13 to different degrees. This makes it easier for the spring 13 to push the ultrasonic transducer body 7 against the outer wall of the mixing tank body 1, thereby improving the descaling efficiency. By setting the limiting groove 16 and the limiting block 17 in cooperation, the ultrasonic transducer body 7 can be prevented from accidentally falling out of the mounting base 8.

[0032] In practical use, the device is moved to the designated position, and multiple sets of ultrasonic transducer bodies 7 are connected to an external ultrasonic transmitter. When it is necessary to clean the inner wall of the mixing tank body 1, the adjusting screw 15 is rotated in sequence so that the output ends of the multiple sets of ultrasonic transducer bodies 7 contact the outer wall of the mixing tank body 1. Then, the ultrasonic transducer bodies 7 are started, and the ultrasonic transducer bodies 7 convert electrical energy into high-frequency vibration mechanical energy, which drives the tank wall of the mixing tank body 1 to generate high-frequency vibration, thereby causing the residues attached to the inner wall of the mixing tank body 1 to fall off. The motor 10 is started, and the output end of the motor 10 drives the lead screw 6 to rotate, causing the moving seat 5 to move. The moving seat 5 drives the moving ring 4 to move, and through the fixed seat 9 and the mounting seat 8, it drives the ultrasonic transducer bodies 7 to move, thereby cleaning the residues in different positions of the mixing tank body 1. The operator can also add clean water into the mixing tank body 1 and cooperate with the stirring components inside the mixing tank body 1 to drive the clean water flow. The water flow can wash down the loose residues, thereby improving the cleaning efficiency.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
