Description

Technical Field

[0001] The utility model relates to the technical field of cement products, in particular to a steam curing device for cement product production. Background Art

[0002] During the production of cement products in winter, coagulation promotion is required. Since the temperature in winter is relatively low, after the cement products are poured, the hydration reaction rate of cement is relatively low, resulting in slow solidification of cement. When the temperature is lower than 5 degrees Celsius, the hydration reaction of cement will stop. Therefore, in order to accelerate the solidification of cement, a high-temperature and high-humidity environment should be provided for the cement products to promote the solidification rate of the cement products. The existing method is to use a steam generator to provide a high-temperature and high-humidity environment for the cement products to promote the solidification rate of the cement. However, the steam output direction of the existing steam generator is fixed, which cannot ensure that all cement products are in full contact with the steam. Moreover, due to the fixed steam output direction of the steam generator, the temperature of the part where the steam accumulates is relatively high, and the temperature of the cement products far from the steam output end is relatively low. Based on the above situation, it is necessary to design a steam curing device for cement product production to solve the above problems. Content of the Utility Model

[0003] The utility model provides a steam curing device for cement product production to solve the problems in the prior art that the orientation of the steam output end of the steam generator is fixed, resulting in that some cement products cannot be in full contact with water vapor and the temperature around all cement products cannot be guaranteed to be consistent.

[0004] The technical problems solved by the utility model are realized by adopting the following technical solutions:

[0005] A steam curing device for cement product production includes a steam generator and a placement rack. A plurality of trays for supporting cement products are arranged at intervals on the placement rack. A discharge pipe is arranged at the output end of the steam generator and is located below the trays. A plurality of steam spray nozzles are arranged on the discharge pipe. A driving component for driving the steam generator to move is also arranged on one side of the placement rack.

[0006] Preferably, the driving component includes a support plate fixed to the bottom of the steam generator, a threaded sleeve fixed to the lower part of the support plate, a rectangular groove arranged below the support plate, a threaded rod located in the middle of the rectangular groove and rotatably connected to the rectangular groove, and a driving motor for driving the threaded rod to rotate. The threaded sleeve is in threaded cooperation with the threaded rod.

[0007] Preferably, rollers capable of abutting against the upper surface of the rectangular groove are installed at the bottom of the support plate.

[0008] Preferably, first touch switch and second touch switch for adjusting the rotation direction of the driving motor are respectively arranged at two ends of the rectangular groove.

[0009] Preferably, both the steam generator and the placement rack are arranged inside a closable steam chamber.

[0010] Preferably, an opening and closing door plate is arranged on the steam chamber for controlling the opening and closing of the steam chamber.

[0011] The beneficial effects of the present utility model are as follows: By arranging a driving component to drive the steam generator to move, the orientation of the output end of the steam generator is changed, so that the steam at the output end of the steam generator can fully and evenly contact each cement product, and at the same time, the temperatures of each cement product are ensured to quickly tend to be consistent.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] The existing steam curing device is a steam generator 4. At the output end of the steam generator 4, there is a steam discharge pipe 5. The hot steam ejected through the steam discharge pipe 5 is used to heat up and moisturize the cement products. Since the existing steam generator 4 is mostly in a static state when curing the cement products by steam, the steam ejection direction at the output end of the steam generator 4 is a fixed direction, and the steam can only contact part of the cement products. Moreover, due to the fixed steam ejection direction, the temperatures of multiple cement products are uneven. The cement products directly contacting the steam have a higher temperature, while the cement products indirectly contacting the steam have a lower temperature, and the temperature difference between multiple cement products is relatively large. Based on the above problems, the present utility model makes the following improvements.

[0022] Reference Figure 1 , the produced cement products are displayed and placed through the trays 2 on the placement rack 1. The steam generator 4 is arranged on one side of the placement rack 1, and a discharge pipe 5 located below the tray 2 is provided at the output end of the steam generator 4. A plurality of steam nozzles 6 are arranged on the discharge pipe 5. When the hot steam generated by the steam generator 4 is ejected from the plurality of steam nozzles 6, the steam will move upward due to its heat and dissipate on the cement products above to heat up and moisturize the cement products. In order to enable all the cement products on the placement rack 1 to contact the dissipated water vapor, a driving assembly 7 is added on one side of the placement rack 1 to drive the steam generator 4 to move, so that the discharge pipe 5 at the output end of the steam generator 4 moves below the tray 2, thereby changing the steam output direction in real time, achieving the purpose of uniformly heating and moisturizing the cement products on the placement rack 1. It should be noted that the trays 2 on the placement rack 1 are arranged at intervals. Since there are gaps between the trays 2, channels 3 are formed between multiple cement products to facilitate the circulation and dissipation of steam.

[0023] Further, the driving component 7 includes a support plate 701 fixed to the bottom of the steam generator 4, a threaded sleeve 702 fixed to the lower part of the support plate 701, a rectangular groove 703 provided below the support plate 701, a threaded rod 704 located in the middle of the rectangular groove 703 and rotatably connected to the rectangular groove 703, and a driving motor 705 for driving the threaded rod 704 to rotate. The threaded sleeve 702 is in threaded cooperation with the threaded rod 704. The driving component 7 can be implemented by the above-mentioned lead screw driving structure. When the driving motor 705 rotates forward, it drives the threaded rod 704 to rotate. The threaded rod 704 drives the steam generator 4 on the support plate 701 to perform a linear motion through the threaded sleeve 702. When the driving motor 705 rotates in reverse, the threaded rod 704 drives the steam generator 4 to perform a reverse linear motion through the threaded sleeve 702.

[0024] Further, a roller 707 capable of abutting against the upper surface of the rectangular groove 703 is installed at the bottom of the support plate 701. In order to make the movement of the steam generator 4 smoother, the roller 707 is added at the bottom of the support plate 701, which can reduce the friction between the support plate 701 and the upper surface of the rectangular groove 703. By changing the sliding friction into rolling friction through the roller 707, the steam generator 4 on the support plate 701 can move more smoothly. The upper surface of the rectangular groove 703 is provided with a rounded corner portion 706 that fits with the roller 707.

[0025] Further, a first touch switch 8 and a second touch switch 9 for adjusting the rotation direction of the driving motor 705 are respectively provided at both ends of the rectangular groove 703. In order to enable the steam generator 4 to automatically reverse its direction when moving to both ends of the rectangular groove 703, the first touch switch 8 and the second touch switch 9 are respectively provided at both ends of the rectangular groove 703. When the steam generator 4 moves to one end of the rectangular groove 703, the rotation direction of the driving motor 705 can be changed by colliding with the touch switch, thereby realizing the adjustment of the movement direction of the steam generator 4. Of course, the method of adjusting the rotation direction of the driving motor 705 is not limited to the touch switch method. It can also use a frequency converter to adjust the number of forward and reverse movement cycles of the motor to realize the reciprocating movement of the steam generator 4 on the rectangular groove 703. There are many ways to adjust the forward and reverse rotation of the driving motor 705, which will not be elaborated in detail here.

[0026] Further, in order to avoid waste of steam, the steam generator 4 and the placement rack 1 can be placed inside a closable steam chamber 10, thereby reducing the overflow of steam and avoiding the loss of a large amount of heat and moisture in the steam.

[0027] Further, an opening and closing door panel 11 is provided on the steam chamber 10, which can control the opening and closing of the steam chamber 10 and facilitate the loading and unloading of the placement rack 1.

[0028] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will also have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed.
