Description

Technical Field

[0001] This application relates to the field of mixing equipment technology, and in particular to a temperature and humidity controlled concrete mixing device. Background Technology

[0002] Concrete mixing tanks are an indispensable key piece of equipment in construction, widely used in various construction sites. Traditionally, concrete mixing tanks are mainly used to uniformly mix raw materials such as cement, sand, and water to prepare high-quality concrete. With the increasing complexity and high standards of modern engineering projects, higher requirements have been placed on concrete quality control. Especially under different seasons and climates, temperature and humidity have a significant impact on concrete quality; therefore, ensuring the consistency and stability of concrete has become an important research topic. Utility Model Content

[0003] To overcome the above-mentioned technical problems, this application provides a temperature and humidity controlled concrete mixing device.

[0004] This application provides a temperature and humidity controlled concrete mixing device, which adopts the following technical solution:

[0005] The system includes a base, a steam tank, and a mixing tank. A heating chamber is fixedly installed at the bottom of the base. The mixing tank includes an outer shell, a mixing inner liner, and a cover. The mixing inner liner is placed inside the outer shell, and a temperature regulating chamber is formed between the mixing inner liner and the outer shell. A temperature regulating pipe is installed in the temperature regulating chamber. The temperature regulating pipe is spiral-shaped and fixedly installed on the outer surface of the mixing inner liner. A mixing chamber is opened inside the mixing inner liner. The cover seals the mixing chamber and the temperature regulating chamber. A stirring blade is vertically installed in the mixing chamber. Multiple vertical baffles are arranged in a ring on the inner wall of the mixing chamber. A steam valve is installed in the vertical baffles. The steam valve is connected to the steam tank through a pipe.

[0006] By adopting the above technical solutions, the quality problems caused by temperature and humidity changes during concrete production and use can be effectively solved. The spiral temperature-regulating pipe design ensures more uniform heat distribution, maintaining a consistent temperature throughout the mixing chamber, thus preventing overcooling and improving the quality stability of the concrete. The annular vertical baffles on the inner wall of the mixing chamber not only increase friction during mixing, allowing for more thorough material mixing, but also release appropriate amounts of steam through the built-in steam valve to regulate humidity within the mixing chamber, preventing rapid moisture evaporation in summer. The vertically arranged mixing blades help improve mixing efficiency, ensuring uniform mixing of all concrete components and further enhancing product quality.

[0007] A temperature sensor and a humidity sensor are fixedly installed on the side of the cover near the stirring chamber.

[0008] By adopting the above technical solution, it is possible to monitor the temperature and humidity changes within the mixing chamber in real time during concrete mixing. This helps to adjust the working status of the temperature control pipes in a timely manner, preventing concrete quality problems caused by excessively high or low temperatures, and ensuring the stable performance of concrete under different seasons and environmental conditions. Temperature sensors can effectively monitor the heat situation during the mixing process, avoiding rapid moisture evaporation due to high summer temperatures or freezing problems caused by low winter temperatures; while humidity sensors can accurately reflect excessively high or low humidity within the mixing chamber, thereby allowing for appropriate measures to ensure the optimal moisture content of the concrete mixture.

[0009] A detection component is also fixedly installed on the cover. The detection component includes an insulating shell, a resistance detection rod and a driving cylinder for driving the resistance detection rod are installed inside the insulating shell, and a through hole is opened on the cover for the resistance detection rod to extend into the stirring chamber.

[0010] By adopting the above technical solution, it is possible to monitor the changes in the conductivity of concrete in real time during the mixing process, thereby indirectly reflecting the moisture content in the concrete. The resistance probe can accurately measure the internal resistance value of the concrete, and the driving cylinder can extend or retract the resistance probe into or out of the mixing chamber when needed, ensuring the safety and convenience of the testing operation.

[0011] The end of the resistance detection rod furthest from the drive cylinder is fixedly equipped with a positive electrode block and a negative electrode block.

[0012] By adopting the above technical solution, a positive electrode and a negative electrode are fixedly installed at the end of the resistance detection rod away from the driving cylinder, which can effectively detect the conductivity of concrete in the mixing chamber. When the resistance detection rod is inserted into the mixing chamber, the resistance value between the positive and negative electrodes can reflect the water content inside the concrete.

[0013] The heating chamber is equipped with a pulse igniter and a fuel valve.

[0014] By adopting the above technical solutions, the internal temperature of the mixing tank can be effectively increased in low-temperature environments, preventing the concrete from freezing due to excessively low temperatures. The combined use of the pulse igniter and fuel valve enables precise control of the heating process, ensuring heating efficiency while avoiding energy waste.

[0015] The steam tank is equipped with a steam chamber and a water chamber, which are connected to each other.

[0016] By adopting the above technical solution, the connection between the steam chamber and the water chamber is realized, ensuring that water can smoothly enter the steam chamber to generate steam, improving the stability and efficiency of steam supply, and thus ensuring the continuity of the temperature control process.

[0017] A steam pipe is installed at the top and bottom of the steam chamber, and the other end of each steam pipe is connected to a temperature control pipe.

[0018] By adopting the above technical solution, high-temperature steam in the steam chamber can be transferred to the temperature control pipe through the steam pipe, thereby heating or insulating the mixing tank. This helps prevent the concrete inside the tank from freezing in winter.

[0019] The mixing tank is also equipped with a filling port and a discharging port.

[0020] By adopting the above technical solution, the mixing tank is equipped with a feeding port and a discharge port, making the loading and unloading of concrete more convenient and faster, and improving work efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By setting up temperature control pipes and steam pipes, precise temperature control inside the mixing tank is achieved, effectively solving the problems of rapid moisture evaporation at high temperatures and material freezing at low temperatures, thus improving the consistency and stability of concrete production quality.

[0023] 2. Temperature and humidity sensors on the cover monitor environmental parameters inside the mixing chamber in real time, and dynamically adjust them in conjunction with the resistance detection rod in the detection component, realizing automated management, reducing the need for manual intervention, and improving work efficiency;

[0024] 3. The vertical baffles installed on the inner wall of the mixing chamber help increase the resistance to material flow, making the concrete mix more uniform. At the same time, the humidification amount in each area can be flexibly adjusted through the steam valve, further optimizing the concrete preparation process. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a temperature and humidity controlled concrete mixing device, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a base 1, a steam tank 2, and a stirring tank 3. A heating chamber 11 for heating the steam tank 2 is fixedly installed at the bottom of the base 1. The heating chamber 11 contains a pulse igniter 12 and a fuel valve 13. The pulse igniter 12 and the fuel valve 13 work together to burn fuel within the heating chamber 11, thereby heating the steam tank 2 at the top. The steam tank 2 contains a steam chamber 22 and a water chamber 21, which are connected. The base 1, corresponding to the heating chamber 11, is made of conventional heat-conducting metal. The flame heats the ceramic plates, causing the water in the water chamber 21 to boil and generate steam. The top of the water chamber 21 is connected to the steam chamber 22, and the steam generated after heating accumulates in the steam chamber 22.

[0031] The mixing tank 3 includes an outer shell 33, an inner mixing liner 31, and a cover 4. The inner mixing liner 31 is placed inside the outer shell 33, and a temperature regulating cavity 32 is formed between the inner mixing liner 31 and the outer shell 33. A temperature regulating pipe 321 is provided inside the temperature regulating cavity 32. The temperature regulating pipe 321 is spiral-shaped and fixedly installed on the outer surface of the inner mixing liner 31. A mixing chamber 313 is formed inside the inner mixing liner 31. The mixing tank 3 also has a filling port 44 and a discharging port 45. Both the filling port 44 and the discharging port 45 pass through the outer shell 33 and are connected to the mixing chamber 313. The cover 4 seals the mixing chamber 313 and the temperature regulating cavity 32. The mixing chamber 313 has vertically arranged stirring blades 34, and multiple vertical baffles 312 are arranged in a ring on the inner wall of the mixing chamber 313. The vertical baffles 312 are vertically arranged. A steam valve 311 is installed inside the vertical baffle 312. The steam valve 311 is connected to the steam tank 2 via a pipe, and specifically, the steam valve 311 is connected to the steam chamber 22 via a pipe. The pipe diverts the steam in the steam chamber 22 separately. By controlling the valve of the steam valve 311, the steam can be injected into the stirring chamber 313, thereby directly humidifying the stirring chamber 313. A steam pipe 23 is installed at the top and bottom of the steam chamber 22. The steam pipe 23 is connected to the steam chamber 22 by a conventional valve for opening and closing. The other end of the steam pipe 23 is connected to the temperature regulating pipe 321. One of the two steam pipes 23 is used for diversion and the other for return. In order to improve the utilization efficiency of steam, the steam pipe 23 at the top of the steam chamber 22 is used for diversion, and the steam pipe 23 at the bottom is used for return.

[0032] A temperature sensor 41 and a humidity sensor 42 are fixedly installed on the side of the cover 4 near the stirring chamber 313. The temperature sensor 41 and the humidity sensor 42 detect the temperature and humidity inside the stirring chamber 313 and control the timing of the steam valve 311 and the temperature regulating pipe 321.

[0033] A detection assembly is also fixedly installed on the cover 4. The detection assembly includes an insulating shell 441, inside which a resistance detection rod 431 and a driving cylinder 43 for driving the resistance detection rod 431 are installed. The cover 4 has a through hole for the resistance detection rod 431 to extend into the mixing chamber 313. A positive electrode block 432 and a negative electrode block 433 are fixedly installed at the end of the resistance detection rod 431 away from the driving cylinder 43. The driving cylinder 43 can drive the resistance detection rod 431 to extend into the mixing chamber 313. When the positive electrode block 432 and the negative electrode block 433 come into contact with the concrete, a closed circuit is generated. Based on this, a conventionally installed voltmeter can be added to detect the resistance of the concrete. When the moisture content inside the concrete is different, the resistance of the concrete is different. This setting can detect the moisture content in the concrete and, together with the humidity sensor 42, accurately control the timing of humidification.

[0034] The implementation principle of this application embodiment is as follows: When the external temperature is low, the steam tank 2 can generate steam to heat the mixing chamber 313 through the steam pipe 23 and the temperature regulating pipe 321. By setting the steam valve 311, the mixing chamber 313 can be humidified when the humidity is low to prevent the concrete from solidifying. When the concrete is stored in the mixing tank 3 for a long time, the temperature and humidity inside the mixing chamber 313 are intelligently detected by the temperature sensor 41 and the humidity sensor 42, and the resistance of the concrete is accurately detected by the resistance detection rod 431. This determines whether to heat or humidify the concrete, thereby enabling precise control of the concrete and reducing energy consumption.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
