Description

Technical Field

[0001] The utility model relates to the technical field of cement curing, and specifically, to an automatic humidification replenishing device for a cement constant temperature and humidity curing box. Background Art

[0002] With the continuous development of concrete technology, the use of high-performance concrete and admixtures, people's attention to the performance of concrete materials has gradually increased. The strength of concrete is a gradually developing process, and its development degree and speed depend on the hydration condition of cement. Temperature and humidity are important factors affecting the hydration speed and degree of cement. During the cement testing process, curing boxes are mostly used to complete the curing of cement samples, which has the advantages of simple operation, stable structure, and good curing effect in actual use.

[0003] The prior art discloses an automatic water replenishing and spraying device for a cement constant temperature and humidity curing box with the publication number of CN214026296U, which includes an external water replenishing unit, a tap water inlet, a filter, an external water replenishing tank, a water tank inlet, a water tank outlet, a water level control mechanism, a float valve switch, a high liquid level, a low liquid level, an internal humidifying unit, a humidifier control switch, an ultrasonic humidifier water tank, a humidifier inlet, and a humidifying air output pipe. The filter and the new type of water-saving float valve switch are connected from the tap water inlet to the newly added external water replenishing tank through a water pipe; the water tank outlet and the humidifier inlet are connected through a water pipe; the tap water inlet is kept in an open state, and water is injected into the external water replenishing tank through the float valve switch until the water level reaches the high liquid level, and the new type of water-saving float valve switch automatically closes; at this time, the horizontal position of the high liquid level is higher than the humidifier inlet, forming a water pressure difference; when the humidifier control switch is turned on, water flows from the water tank outlet to the humidifier inlet, and the lower part of the humidifier working body starts to prepare clean air with a certain humidity and outputs it to the working place through the humidifying air output pipe; when the high liquid level of the water in the external water replenishing tank decreases to the low liquid level, the new type of water-saving float valve switch is immediately triggered to open, so that the water in the external water replenishing tank reaches the high liquid level. When the humidifier works for a long time according to the above cycle principle, it can ensure that the water in the external water replenishing tank is not lower than the low liquid level, thus ensuring the long-term stable operation of the ultrasonic humidifier.

[0004] In the above-mentioned utility model, the mist enters the interior of the curing box through the humidifying air output pipe. Due to the relatively large space inside the curing box, the mist cannot quickly contact the cement samples to be cured, reducing the practicality of this utility model. At the same time, tap water needs to be filtered by the filter before being discharged into the ultrasonic humidifier water tank. When the filter needs to be cleaned, the self-draining discharge work needs to be stopped, and this method will affect the humidification replenishing work of this utility model.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present utility model provides an automatic humidification device for a cement constant temperature and humidity curing box, having the following beneficial effects:

[0018] (1) The present utility model adopts a shaft tube. Before actually using the automatic humidification device for the cement constant temperature and humidity curing box, first connect the other end of the second three-way pipe to an external water pump, and then connect the external water pump to the controller through an electric wire. When the clear water level inside the water tank touches the lower group of liquid level sensors, the lower group of liquid level sensors send a signal to the controller, and the controller makes the external water pump work. Tap water can sequentially enter the inside of the water tank through the external water pump, the second three-way pipe, the filter box and the first three-way pipe. When the clear water level inside the water tank touches the upper group of liquid level sensors, the upper group of liquid level sensors send a signal to the controller to stop the external water pump.

The pumping unit can pump the clear water into the inside of the humidifier through the liquid extraction pipe and the connecting pipe. The water mist generated by the humidifier passes through the mist pipe and the air storage tray, and finally is discharged through the two spray pipes. When the driving motor works, its output end drives the main gear to rotate. Since the main gear meshes with the driven gear, the rotating main gear can push the driven gear to rotate. The rotating driven gear drives the air storage tray and the two spray pipes to rotate through the shaft tube. The mist sprayed through the two rotating spray pipes can quickly contact the cement samples on the placement rack. Through the arranged shaft tube, the mist can quickly contact the cement samples, improving the practicality of the automatic humidification device for the cement constant temperature and humidity curing box.

[0019] (2) The present utility model adopts a filter box. According to the above operations, tap water sequentially passes through the second three-way pipe, the filter box, and the first three-way pipe. During this process, multiple filter plates inside the two cavities can filter impurities in the tap water. When it is necessary to clean the impurities inside the two cavities, the operator closes the upper group of first control valves and the upper group of second control valves by hand, and then utilizes the threaded cooperation of the four connecting screws and the eight connecting nuts. The operator rotates the upper four connecting nuts clockwise and counterclockwise by hand. When the upper two connecting nuts are separated from the upper two connecting screws, the upper group of connecting plates can be pulled out. At this time, multiple upper blocking blocks can be moved out of the internal openings on the same side. The operator can clean the inside of the upper group of cavities through the multiple openings on the same side. At the same time, tap water can be filtered through the lower group of cavities. For the cleaning of the lower group of cavities, open and close the upper group of first control valves and the upper group of second control valves, and at the same time close the lower group of first control valves and the lower group of second control valves. The use of the lower group of connecting plates can be obtained by the same operation. By setting the filter box, the cleaning work of the filtering structure can be completed without stopping the dehumidification work, which provides guarantee for the continuous humidification work of the automatic humidification device of the cement constant temperature and humidity curing box.

Only its use is involved without modification, so the control method and the circuit connection will not be described in detail.

[0037] Working principle:

[0038] Before actually using the automatic moisturizing device of the cement constant temperature and humidity curing box, first connect the other end of the second three-way pipe 12 to the external water pump, and then connect the external water pump to the controller through wires. When the clean water level inside the water tank 2 contacts the lower set of liquid level sensors, the lower set of liquid level sensors sends a signal to the controller, and the controller makes the external water pump work. The tap water passes through the external water pump and can enter the interior of the water tank 2 through the second three-way pipe 12, the filter box 11 and the first three-way pipe 10 in turn. When the clean water level inside the water tank 2 contacts the upper set of liquid level sensors, the upper set of liquid level sensors sends a signal to the controller to stop the external water pump. When the humidity inside the curing box 1 reaches the preset value of the humidity sensor, it will send a signal to the controller. The controller sends a signal, and the controller activates the humidifier 3, the pump and the drive motor 23. The pump can draw clean water into the interior of the humidifier 3 through the liquid extraction pipe 4 and the connecting pipe. The water mist generated by the humidifier 3 passes through the mist pipe 5 and the air storage disk 7, and is finally discharged through the two groups of spray pipes 8. When the drive motor 23 is working, its output end drives the main gear 24 to rotate. Since the main gear 24 and the driven gear 25 are engaged with each other, the rotating main gear 24 can drive the driven gear 25 to rotate. The rotating driven gear 25 drives the air storage disk 7 and the two groups of spray pipes 8 to rotate through the shaft tube 6. The mist sprayed by the rotating two groups of spray pipes 8 can quickly contact the cement sample on the placement rack 9. The provided shaft tube 6 can enable the mist to quickly contact the cement sample. The product improves the practicality of the automatic moisturizing device of the cement constant temperature and humidity curing box. At the same time, according to the above operation, tap water passes through the second three-way pipe 12, the filter box 11 and the first three-way pipe 10 in sequence. During this process, the multiple groups of filter plates 26 inside the two groups of cavities 15 can filter impurities in the tap water. When it is necessary to clean the impurities inside the two groups of cavities 15, the operator manually closes the upper group of first control valves 13 and the upper group of second control valves 14, and then uses the four groups of connecting screws 20 and the eight groups of connecting nuts 21 to cooperate with each other. The operator manually rotates the upper four groups of connecting nuts 21 clockwise and counterclockwise. When the upper two groups of connecting nuts 21 are separated from the upper two groups of connecting screws 20, the upper A group of connecting plates 18, at this time, the upper multiple groups of blocking blocks 17 can be moved out of the interior of the same side multiple groups of openings 16, and the operating workers can clean the interior of the upper group of cavities 15 through the same side multiple groups of openings 16. At the same time, tap water can be filtered through the lower group of cavities 15. The cleaning of the lower group of cavities 15 opens and closes the upper group of first control valves 13 and the upper group of second control valves 14, and at the same time closes the lower group of first control valves 13 and the lower group of second control valves 14. The use of the lower group of connecting plates 18 can be obtained by the same operation. By setting up the filter box 11, the cleaning work of the filter structure can be completed without stopping the dehumidification work, which brings protection for the continuous moisturizing work of the automatic moisturizing device of the cement constant temperature and humidity curing box.
