Description

Technical Field

[0001] The invention belongs to the technical field of concrete curing, and in particular relates to a humidifying device for a concrete standard curing room. Background Art

[0002] With the rapid development of the construction industry, concrete has become one of the most important building materials. The quality of concrete has a decisive influence on the safety, stability and durability of building structures. In order to accurately evaluate the performance of concrete, concrete test blocks must be cured under standard conditions to simulate the curing environment in actual projects. Therefore, standard concrete curing rooms came into being. Standard concrete curing rooms precisely control the temperature, humidity and other parameters of the curing environment to ensure that concrete test blocks complete the curing process under constant and repeatable conditions, thereby providing reliable test samples for concrete performance testing and providing an important basis for project quality control and design optimization.

[0003] At present, most of the humidification devices used in standard concrete curing rooms on the market are in the form of fixed atomizing nozzles, which can easily lead to uneven humidity distribution. The humidity in some areas is too low or too high, affecting the curing effect of the concrete test blocks and ultimately causing distortion of the performance test data. While rotating the atomizing nozzles is conducive to uniform humidity distribution, this usually requires additional power devices such as motors, increasing energy consumption costs.

[0034] 1. The steam generated by the steam engine is discharged from its output port to the connecting pipe, and then sprayed out from each nozzle after passing through the supporting pipe. At the same time, when the steam flows through the connecting pipe and the supporting pipe, the impeller will rotate at high speed under the action of the steam airflow, thereby driving the rotating column to rotate at high speed, and then driving the multi-head nozzle to rotate at high speed as a whole. Finally, the steam is sprayed out through the nozzle in a rotating state. The sprayed steam is violently mixed with the relatively static air around it, and is fully atomized under the action of momentum exchange and strong shearing to form high-pressure micro-mist and extremely fine water mist particles, which are evenly dispersed in the curing room with the help of rotational inertia, which can effectively ensure the uniform distribution of humidity.

[0035] 2. The disc can be driven to rotate by rotating the rotating rod. Under the limiting effect of the circular tube, the disc can drive the cylinder to move up and down in the circular tube when rotating, thereby driving the two opening and closing plates to open and close. The two opening and closing plates gradually open when rotating inward to increase the steam discharge amount, and gradually close when rotating outward to reduce the steam discharge amount. The present invention can control the steam discharge amount of multiple nozzles at the same time by rotating the rotating rod, and the operation is convenient and quick.

[0048] Reference Figure 1-6 , a humidifying device for a standard concrete curing room, comprising a steam engine 1, a connecting pipe 2 and a multi-head nozzle 3;

[0049] One end of the connecting pipe 2 is fixedly connected to the output port of the steam engine 1; the multi-head nozzle 3 is rotatably connected to the other end of the connecting pipe 2;

[0050] The multi-head nozzle 3 includes a support tube 31, a plurality of nozzles 32, a fixed column 33, a rotating column 34 and an impeller 35;

[0051] One end of the support tube 31 is rotatably connected to the connecting tube 2; a plurality of nozzles 32 are connected to the other end of the support tube 31; a fixed column 33 is fixed in the connecting tube 2; a rotating column 34 is fixed in the support tube 31 and rotatably connected to the fixed column 33; an impeller 35 is fixedly sleeved on the rotating column 34.

[0052] When the concrete test block needs to be humidified in the curing room, the steam engine 1 is started, and the steam generated by the steam engine 1 is discharged from its output port to the connecting pipe 2, and then sprayed out from each nozzle 32 after passing through the support pipe 31. At the same time, when the steam flows through the connecting pipe 2 and the support pipe 31, the impeller 35 will rotate at a high speed under the action of the steam airflow, thereby driving the rotating column 34 to rotate at a high speed, and then driving the multi-head nozzle 3 to rotate at a high speed as a whole. Finally, the steam is sprayed out in a rotating state through the nozzle 32, and the sprayed steam is violently mixed with the relatively still air around it, and is fully atomized under the action of momentum exchange and strong shearing to form high-pressure micro-mist and extremely fine water mist particles, which are evenly dispersed in the curing room with the help of rotational inertia, which can effectively ensure the uniform distribution of humidity.

[0053] In a specific embodiment, a groove is formed at the bottom of the rotating column 34 , and the rotating column 34 is rotatably sleeved on the fixed column 33 through the groove.

[0054] In a specific embodiment, a first annular groove 21 is provided on the inner wall of the connecting tube 2, and a protrusion is formed at the tube mouth; a second annular groove 311 is provided on the outer wall of the supporting tube 31, and a protrusion is formed at the tube mouth; the first annular groove 21 and the second annular groove 311 are engaged with the corresponding protrusions, and the supporting tube 31 can rotate relative to the connecting tube 2 without detaching from each other, thereby ensuring the connection strength.

[0055] In a specific embodiment, the number of the nozzles 32 is three, and the three nozzles 32 and the support tube 31 are integrally formed into a cross structure.

[0056] In a specific embodiment, the end of the nozzle 32 connected to the support tube 31 is a cylindrical 432 shell structure, and the end away from the support tube 31 is a conical shell structure, and the tip of the conical shell structure has a steam spray outlet.

[0057] In a specific embodiment, at least four pulleys 10 are installed at the bottom of the steam engine 1 to facilitate movement.

[0060] The disc 41 is rotatably mounted at the connection point between the plurality of nozzles and the support tube 31; one end of the rotating rod 42 is fixedly connected to the disc 41, and the other end passes through the multi-head nozzle 3; a plurality of flow control components 43 are respectively mounted in the nozzles 32;

[0061] The flow control assembly 43 includes a round tube 431, a cylinder 432, a round rod 433, a fixing rod 434, two opening and closing plates 435 and two connecting rods 436;

[0062] The circular tube 431 is fixed in the nozzle 32; the cylinder 432 is movably arranged in the circular tube 431; one end of the circular rod 433 is hinged to the cylinder 432, and the other end is hinged to the outer wall of the disc 41; the fixing rod 434 is fixed in the nozzle 32, and is located on the side of the cylinder 432 away from the disc 41; the two opening and closing plates 435 are arranged opposite to each other, and are both hinged to the fixing rod 434; one end of the two connecting rods 436 is respectively hinged to the two clamping plates, and the other end is hinged to the cylinder 432.

[0063] When the concrete test block requires different humidity, it is necessary to control the steam ejection amount. The staff can drive the disc 41 to rotate by rotating the rotating rod 42. Under the limiting effect of the circular tube 431, the disc 41 can drive the cylinder 432 to move up and down in the circular tube 431 when rotating, thereby driving the two opening and closing plates 435 to open and close. When the two opening and closing plates 435 rotate inward, they gradually open to increase the steam discharge amount. When the two opening and closing plates 435 rotate outward, they gradually close to reduce the steam discharge amount. The present invention can simultaneously control the steam discharge amount of multiple nozzles 32 by rotating the rotating rod 42, and the operation is convenient and quick.

[0064] Preferably, in this embodiment, when the two opening and closing plates 435 are rotated outwards to be flush, they are completely in contact with the inner wall of the nozzle 32 and cannot be rotated outwards any further. At this time, the steam is in a completely closed state.

[0065] In a specific embodiment, the two opening and closing plates 435 are semicircular plate structures, wherein the opposite sides are concave and convex structures that match each other.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
