Description

Technical Field

[0001] This application belongs to the field of concrete mixing technology, and in particular relates to a concrete heating and mixing device for winter construction. Background Technology

[0002] Concrete mixing is the process of mechanically mixing cement, sand, gravel, and water in a certain proportion to form a homogeneous mixture. This process is usually carried out in a mixer. The mixing action ensures that the various components in the concrete are evenly distributed to guarantee the quality and performance of the concrete. The purpose of concrete mixing is to fully mix the various components of the concrete to achieve good workability and strength, and to ensure the final construction effect.

[0003] The existing utility model with authorization announcement number CN221892256U discloses a concrete mixing device, including a cylindrical tank with an open top, supports fixedly connected to both sides of the bottom of the cylindrical tank, the inner wall of the bottom of the cylindrical tank being set as a conical structure, a discharge valve being fixedly connected to the bottom of the cylindrical tank, and a cover plate being fixedly installed on the top of the cylindrical tank, with a concrete feed baffle assembly embedded and fixed on the top left side of the cover plate.

[0004] The above technical solution, through the combination of a cylindrical tank, cover plate, drive motor, rotating box, concrete feed baffle assembly, and circumferentially rotating mixing assembly, can utilize a single-drive integrated control of two mixing shafts and multiple first mixing blades to achieve rapid and uniform mixing in both directions, improving mixing uniformity and efficiency. However, this technical solution lacks heating and mixing functions, which can lead to concrete freezing inside the mixing equipment during winter construction, potentially affecting the quality of concrete construction. Furthermore, after use, concrete can still adhere to the inner wall of the mixing equipment, which, once solidified, can not only affect subsequent mixing quality but also the heating effect, resulting in limited practicality.

[0005] Therefore, we propose a concrete heating and mixing equipment for winter construction to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem in the prior art that it is inconvenient to heat and clean during mixing, and to propose a concrete heating and mixing equipment for winter construction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A concrete heating and mixing device for winter construction includes a mixing drum. A water storage tank is fixedly connected to the outer surface of the mixing drum. Two heaters are fixedly installed on the inner wall of the water storage tank. A water pump is fixedly connected to the upper surface of the water storage tank. The input end of the water pump's power passes through the water storage tank and extends into its interior. The output end of the water pump's power is fixedly connected to a multi-port nozzle. The outer surface of the multi-port nozzle is fixedly connected to the inner wall of the mixing drum. A heat-conducting cylinder is fixedly connected to the inner wall of the mixing drum. A heating tube is fixedly connected to the outer surface of the heat-conducting cylinder. A servo motor is fixedly connected to the upper surface of the mixing drum. The output end of the servo motor passes through the mixing drum and is fixedly installed with a mixing shaft. The bottom end of the mixing shaft is rotatably connected to the inner wall of the mixing drum. A cleaning frame is fixedly connected to the bottom end of the mixing shaft. The outer surface of the cleaning frame contacts the inner wall of the heat-conducting cylinder, and the bottom surface of the cleaning frame contacts the inner bottom wall of the mixing drum.

[0009] Preferably, the outer surface of the stirring cylinder is fixedly connected to three support legs, and the bottom surface of each support leg is fixedly connected to a base.

[0010] Preferably, the front and back of the water storage tank are fixedly connected with reinforcing blocks, and the outer surface of each reinforcing block is fixedly connected to the outer surface of the stirring drum.

[0011] Preferably, a cylinder cover is slidably connected to the inner wall of the mixing cylinder, and a pull block is fixedly connected to the upper surface of the cylinder cover.

[0012] Preferably, a water injection pipe is fixedly connected to the left side of the water storage tank, and a plug is slidably connected to the inner wall of the water injection pipe.

[0013] Preferably, the inner wall of the stirring cylinder is slidably connected to a protective shell, and the protective shell has three through holes on both the front and back sides.

[0014] Preferably, the inner wall of the protective shell is threaded with four bolts, and the bottom end of each bolt is threaded to the inner wall of the mixing cylinder.

[0015] In summary, the technical effects and advantages of this application are as follows:

[0016] By installing a heater, heated water is sprayed into the mixing drum through a multi-port nozzle using a water pump. Simultaneously, heating pipes outside the heat-conducting cylinder also provide heating. This dual heating method effectively ensures the mixing effect of the concrete inside the drum, preventing concrete from freezing and thus avoiding disruption to normal winter construction. Secondly, a cleaning rack is installed at the bottom of the mixing shaft. This rack contacts the inner wall of the heat-conducting cylinder and the bottom wall of the mixing drum. With the rotation of the mixing shaft and the water spray from the multi-port nozzles, the cleaning rack effectively cleans residual concrete from the inner walls of the mixing drum and the heat-conducting cylinder. This prevents concrete from solidifying on the drum walls, ensuring that subsequent mixing quality is not affected and that the heating effect is not adversely affected. This greatly improves the practicality of the equipment. Compared to traditional equipment, this invention effectively solves the problems of concrete heating and mixing and equipment cleaning during winter construction, improving the efficiency and quality of concrete construction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4A concrete heating and mixing device for winter construction includes a mixing drum 1. A water storage tank 2 is fixedly connected to the outer surface of the mixing drum 1. Two heaters 10 are fixedly installed on the inner wall of the water storage tank 2. A water pump 11 is fixedly connected to the upper surface of the water storage tank 2. Three support legs 4 are fixedly connected to the outer surface of the mixing drum 1. A base 5 is fixedly connected to the bottom surface of each support leg 4. The support legs 4 and the base 5 provide a stable support structure for the mixing drum 1. The stable support structure can prevent the mixing equipment from shaking due to uneven ground or external impact, ensuring the stability of the mixing process, thereby ensuring the uniformity and quality of concrete mixing. At the same time, the distribution of the three support legs 4 can make the force more even, further enhancing the stability of the entire equipment.

[0024] The power input end of the water pump 11 passes through the water storage tank 2 and extends into the interior of the water storage tank 2. Reinforcing blocks 3 are fixedly connected to both the front and back of the water storage tank 2. The outer surface of each reinforcing block 3 is fixedly connected to the outer surface of the mixing drum 1. The presence of the reinforcing blocks 3 strengthens the connection between the water storage tank 2 and the mixing drum 1. The reinforcing blocks 3 can prevent the connection between the water storage tank 2 and the mixing drum 1 from loosening. In addition, during the operation of the equipment, the reinforcing blocks 3 can share the weight of the water storage tank 2 and the force generated by the internal water shaking, etc., protect the connection between the water storage tank 2 and the mixing drum 1, and extend the service life of the equipment.

[0025] The output end of the water pump 11 is fixedly connected to a multi-port nozzle 12. The outer surface of the multi-port nozzle 12 is fixedly connected to the inner wall of the mixing drum 1. A heat-conducting cylinder 16 is fixedly connected to the inner wall of the mixing drum 1. A drum cover 6 is slidably connected to the inner wall of the mixing drum 1. A pull block 7 is fixedly connected to the upper surface of the drum cover 6. The drum cover 6 can seal the mixing drum 1 during the mixing process to prevent heat loss and help maintain the temperature inside the mixing drum 1 in winter, thereby ensuring the effect of concrete heating and mixing. The pull block 7 makes it convenient for operators to open and close the drum cover 6, improving the convenience of operation. Moreover, when it is necessary to check the internal condition of the mixing drum 1 or add materials, the drum cover 6 can be quickly opened for operation.

[0026] A heating tube 17 is fixedly connected to the outer surface of the heat-conducting cylinder 16. A servo motor 18 is fixedly connected to the upper surface of the stirring cylinder 1. The power output end of the servo motor 18 passes through the stirring cylinder 1 and is fixedly installed with a stirring shaft 19. A water injection pipe 8 is fixedly connected to the left side of the water storage tank 2. A plug 9 is slidably connected to the inner wall of the water injection pipe 8. The water injection pipe 8 facilitates the injection of water into the water storage tank 2 to meet the water demand during the stirring process. The plug 9 can effectively prevent water leakage when it is not needed, and ensure the water level in the water storage tank 2 is stable.

[0027] The bottom end of the stirring shaft 19 is rotatably connected to the inner wall of the stirring drum 1. A cleaning rack 20 is fixedly connected to the bottom end of the stirring shaft 19. A protective shell 13 is slidably connected to the inner wall of the stirring drum 1. Three through holes 14 are provided on the front and back of the protective shell 13. The protective shell 13 can provide good protection for the servo motor 18 and avoid accidental collision with the servo motor 18. At the same time, the through holes 14 can facilitate the heat dissipation of the motor and also facilitate the wiring connection of the motor.

[0028] The outer surface of the cleaning frame 20 is in contact with the inner wall of the heat-conducting cylinder 16, and the bottom surface of the cleaning frame 20 is in contact with the inner bottom wall of the mixing cylinder 1. The inner wall of the protective shell 13 is threaded with four bolts 15, and the bottom end of each bolt 15 is threaded to the inner wall of the mixing cylinder 1. This connection method can firmly fix the protective shell 13 to the mixing cylinder 1. During winter construction, the vibration of the equipment may be relatively large. The connection of the bolts 15 can ensure that the protective shell 13 will not be displaced due to vibration, thereby continuously and effectively protecting the motor. It also facilitates disassembly when the protective shell 13 needs to be repaired or replaced.

[0029] The working principle of this utility model is as follows: In use, the operator first connects the electrical equipment to an external power source. Simultaneously, a hole is provided on the rear surface of the mixing drum 1 to facilitate connection of the heating element 17's power cord to the external power source. Then, the mixing drum 1 is opened through the drum cover 6 to add concrete raw materials. Subsequently, the operator controls the heater 10 and heating element 17 via the controller. Since both heater 10 and heating element 17 integrate WiFi modules, they can be controlled wirelessly. The heater 10 and heating element 17 are then adjusted to a suitable temperature to avoid excessively high or low temperatures. The heater 10 heats the water in the water storage tank 2. Then, the water pump 11 and servo motor 18 are activated. The water pump 11 draws water from the water storage tank 2 and sprays it into the mixing drum 1 through the multi-port nozzle 12. The heat-conducting cylinder 16 in the mixing drum 1 has a heating pipe 17 on its outside, which can also provide heat to the concrete in the mixing drum 1. The servo motor 18 starts, and the mixing shaft 19 at its output end starts to rotate. The mixing shaft 19 drives the cleaning frame 20 to rotate, thereby heating and mixing the concrete. The heat-conducting cylinder 16 can be made of metal or copper, which not only has good thermal conductivity but is also durable. Finally, when using concrete, the concrete is discharged through the discharge pipe at the bottom. Then, the water pump 11 is turned on again to spray water through the multi-port nozzle 12. With the cooperation of the rotating cleaning frame 20, the cleaning frame 20 can clean both the inner wall of the heat-conducting cylinder 16 and the inner bottom wall of the mixing drum 1.
