Description

Technical Field

[0001] The utility model relates to a solar energy and steam auxiliary heating type ceramsite curing bin, belonging to the technical field of ceramsite production. Background Art

[0002] According to the production process of ceramsite, the preparation process of ceramsite can be divided into two types: unfired ceramsite and sintered ceramsite. Unfired ceramsite is ceramsite that does not require high-temperature roasting. This type of ceramsite is made of various active solid wastes (fly ash, coal gangue, etc.), binders, admixtures and other auxiliary materials, and is granulated and then naturally cured under the activity of volcanic ash to form an artificial lightweight aggregate.

[0003] The natural curing of expanded clay mainly involves covering the expanded clay yard with wetting materials, or directly using a sprayer to sprinkle water on the surface of the expanded clay to keep the surface of the expanded clay moist. The curing period is generally 14 to 28 days. This curing method is simple and low in cost, but it has the problems of long curing time, large floor space, and inadequate curing of the bottom expanded clay. At present, steam / autoclave curing is more commonly used in the actual production process. This method is to pass steam into the curing bin / autoclave. Under certain pressure conditions, heat and water penetrate into the interior of the expanded clay, accelerate the hydration reaction process of the expanded clay, form more silicate and aluminate crystals, shorten the curing time, and improve the strength of the expanded clay.

[0004] For the curing process of unfired ceramsite, since the curing molding cycle of steam / autoclave curing is usually 3~5 days, it can greatly shorten the curing time, speed up the product turnover efficiency, and occupy a relatively small area. Therefore, autoclave curing equipment represented by autoclaves has gradually been promoted in the preparation process of unfired ceramsite. However, steam curing also has the problems of large one-time investment in equipment and high energy consumption.

[0005] In fact, the selection of ceramsite curing technology should take into account the principle of adapting measures to local conditions and balancing cost and benefit. In view of the shortcomings of several current ceramsite curing methods, it is urgent to develop a ceramsite curing equipment with short curing time, low energy consumption and good curing effect, simplify the ceramsite curing process, improve the ceramsite curing efficiency, and thus improve the economic benefits of ceramsite products. Utility Model Content

[0006] The utility model aims to provide a solar energy and steam auxiliary heating type ceramsite curing bin, which can simplify the ceramsite curing process, improve the ceramsite curing efficiency, and improve the economic benefits of ceramsite products.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0019] Preferably, the heat-absorbing and heat-insulating roof is an inverted V-shaped structure with an angle of 60 to 120 degrees.

[0020] Preferably, the sprayers are provided in plurality and distributed above the shelves, and the steam radiators are provided in plurality and installed inside the insulation wall.

[0021] Preferably, the thermal insulation wall is also provided with a visual window and a sliding door.

[0022] The beneficial effects of the utility model are:

[0023] The expanded clay curing process is integrated into a curing chamber and solar energy curing is used. The curing temperature requirements of expanded clay can be met under natural light conditions. Compared with natural curing and steam curing, it has the advantages of short curing time, small footprint and low curing cost.

[0024] The design of the curing chamber takes into account the conditions of rainy weather and insufficient light energy at night. The inner side of the insulation wall is equipped with a steam radiator. When light energy is insufficient and the temperature drops significantly, steam can be introduced for auxiliary heating, which makes up for the shortcomings of solar energy curing methods. It is suitable for different regions and climatic conditions, has strong adaptability and a wider range of uses.

[0025] The heat-absorbing and heat-insulating structure of the roof, the sandwich insulation structure of the walls on both sides, and the ground insulation and heat storage structure make the curing bin have good insulation effect, which not only saves energy, but also increases the hydration reaction temperature of the expanded clay, strengthens the curing effect of the expanded clay, and has high curing efficiency.

[0032] The heat storage floor 3 consists of a three-layer structure of a base layer 3.1, a heat storage and thermal insulation layer 3.2, and an upper cushion layer 3.3; the base layer 3.1 is the bottom layer, which is a concrete or steel structure base layer (thickness 100~200mm); the heat storage and thermal insulation layer 3.2 is the middle layer, and the material is generally EPS foam board or XPS extruded board (thickness 100~150mm); the upper cushion layer 3.3 is the upper layer, which is a cement mortar or steel plate cushion layer (thickness 30~50mm). The upper cushion layer 3.3 mainly protects the heat storage and thermal insulation layer 3.2 and prevents the heat storage and thermal insulation layer 3.2 from being worn; the heat storage and thermal insulation layer 3.2 can release the heat stored during the day when the temperature is lower at night, so that the curing warehouse will not cool down too quickly at night, and the temperature difference between day and night is reduced; the base layer 3.1 mainly plays a load-bearing and supporting role.

[0033] The insulating wall 2 is composed of an outer wall 2.1, an inner wall 2.3 and an insulating interlayer 2.2 filled between the outer wall 2.1 and the inner wall 2.3. The outer wall 2.1 and the inner wall 2.3 are brick walls made of lightweight insulating bricks or color steel plates; the insulating interlayer 2.2 is a polyvinyl chloride foam plastic board, or filled with insulating materials such as asbestos, rock wool or sponge. The thickness of the insulating interlayer 2.2 is generally 10cm~20cm, and the wall height is generally 1.8m~3.0m.

[0034] The heat-absorbing and heat-insulating roof 1 is composed of a heat-insulating outer layer 1.1 and a heat-absorbing inner layer 1.2. The heat-absorbing inner layer 1.2 is a heat-absorbing coating, which can be a paint coating (PbS coating / iron-copper composite oxide coating), or electroplated black chrome / black nickel / black cobalt coating, or aluminum anodized coloring coating, etc., which absorbs a large amount of solar radiation energy; the heat-insulating outer layer 1.1 is a vacuum laminated glass, and the vacuum design in the middle of the glass can isolate heat loss and has a good heat preservation effect.

[0035] The shelves 5 are arranged on the ground in the curing warehouse at intervals to hold ceramsite, generally 3 to 5 layers. The steam radiator 6 is a coil type, used to transport steam into the curing warehouse to supplement heat in rainy weather and at night when light energy is insufficient. The steam radiator 6 pipe is fixed on the inner side of the wall, and can generally circle 2 to 4 times indoors. Jet holes are punched on the heat dissipation pipe of the steam radiator 6, and after connecting to the external steam supply pipe, steam can be directly sprayed into the curing warehouse to maintain the temperature of the curing warehouse stable through steam auxiliary heating.

[0036] The environmental conditions of the curing chamber are as follows: the curing temperature is 40~80℃, and the relative humidity is 85~98%. The curing cycle is 3~5d. When the temperature is 40~60℃, the curing period is generally 3~5d, and when the temperature is 60~80℃, the curing period is generally 1.5~3d. In actual application, the curing temperature and relative humidity can be detected by sensors and transmitted to the controller for display. Water replenishment and steam injection can be controlled by the controller.
