Description

Technical Field

[0001] This utility model relates to an energy-saving device for the production of lightweight concrete. Background Technology

[0002] In the production of lightweight concrete using existing technology, mixing equipment is required to stir and mix the materials. During the mixing process, a large amount of heat is released. In order to ensure production quality, the internal space of the equipment needs to be cooled. To achieve energy-saving and environmental protection effects, cooling water pipes are generally used to cool the equipment. The cooling water is continuously input and output for heat exchange. Although this method can absorb a large amount of heat, the temperature of the cooling water is relatively low due to the continuous operation of the cooling water. It can only play a role in heat collection and recovery, but its actual effect is not significant. Moreover, the internal stirring mechanism is relatively simple, resulting in low mixing efficiency and the need for continuous stirring, which not only affects work efficiency but also wastes energy.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1-2 As shown, an energy-saving device for the production of lightweight concrete includes a housing 1, a support 2 at the bottom of the housing 1, a motor 3 at the top of the housing 1, a copper pipe 5 on the inner wall of the housing 1, the copper pipe 5 spirally surrounding the inner wall of the housing 1 from bottom to top, a water inlet valve 7 at the upper end of the housing 1, a water outlet valve 8 at the lower end of the housing 1, and a temperature sensor 6 at the connection between the water inlet valve 7 and the copper pipe 5.

[0016] A control box 4 is provided on one side of the housing 1. The control box 4 contains a controller. The inlet valve 7 and the outlet valve 8 are both solenoid valves. The inlet valve 7, the outlet valve 8 and the temperature sensor 6 are all electrically connected to the controller.

[0017] Preferably, cooling water flows through the copper pipe 5 from top to bottom.

[0018] Preferably, the housing 1 is provided with a stirring mechanism, which includes a drive shaft 9, a rotating frame 10 and two stirring units. The drive shaft 9 is vertically arranged inside the housing 1, and the upper end of the drive shaft 9 is connected to the motor 3 for transmission. The rotating frame 10 is arranged at the lower end of the drive shaft 9, and the middle part of the rotating frame 10 is fixedly connected to the lower end of the drive shaft 9. The two stirring units are respectively arranged at both ends of the rotating frame 10, and the two stirring units are symmetrical about the drive shaft 9.

[0019] Preferably, the stirring unit includes a fixing rod 11, which is parallel to the drive shaft 9. The lower end of the fixing rod 11 is fixed to the rotating frame 10, and a plurality of spiral blades 12 are evenly arranged on the fixing rod 11 from top to bottom.

[0020] During operation, the motor 3 drives the drive shaft 9 to rotate, which in turn drives the rotating frame 10 to rotate, thereby driving the two stirring units to stir the material inside the shell 1. During stirring, the material is driven to rise under the action of the spiral blades 12. While rotating and disturbing, the material is disturbed up and down, which improves the stirring effect, increases the stirring efficiency, and indirectly achieves the effect of energy saving.

[0021] During stirring, the cooling water inside the copper tube 5 absorbs the heat emitted from the shell 1, thereby achieving the purpose of cooling.

[0022] Temperature sensor 6 detects the cooling water at the connection between inlet valve 7 and copper pipe 5. When the temperature reaches the preset value, the controller controls outlet valve 8 and inlet valve 7 to open. According to the preset valve opening time, the heated cooling water is discharged from outlet valve 8, and the low-temperature cooling water enters copper pipe 5 from inlet valve 7. The drainage time can be set according to the actual water volume and drainage efficiency in copper pipe 5. The purpose of this setting is to ensure that the heated water is completely discharged and that no large amount of new cooling water is discharged from outlet valve 8, affecting the temperature of the hot water in the front end. When the cooling water has not reached the preset temperature, inlet valve 7 and outlet valve 8 are actually closed, so the cooling water in copper pipe 5 can continue to heat up. Compared with continuous water flow, the cooling water temperature in this solution will be much higher, so the range of applications will be wider. The higher water temperature will also result in a better heating effect for subsequent recycling, such as for high-temperature water baths. In contrast, water in continuous water flow heat exchange can only play a role in heat recovery.

[0023] The cooling water output issue can be addressed by adjusting the temperature sensor 6. In this design, the temperature sensor 6 is located at the tail end. In reality, the water temperature at the temperature sensor 6 is lower than the water temperature around the front housing 1. This is achieved by using a minimum temperature control method, primarily to ensure the overall water temperature inside the copper pipe 5, which also indirectly ensures the output water temperature.

[0024] Compared with existing technologies, this energy-saving equipment for lightweight concrete production controls the heat exchange temperature through the cooperation of temperature sensor 6 and water inlet valve 7, increases the water temperature peak, expands the application range of heat exchange water, and sets up a rotating spiral blade 12 inside to achieve disturbance, improve the mixing effect, increase mixing efficiency, and achieve the purpose of energy saving.

[0025] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
