Description

Technical Field

[0001] The present invention relates to the technical field of building material pretreatment, and particularly to a construction pretreatment device for construction engineering materials. Background Art

[0002] Construction engineering materials refer to various materials used in construction projects (including civil engineering, building engineering, pipeline and equipment installation engineering, and decoration engineering). These materials constitute the physical part of buildings or infrastructure and are key factors in ensuring project quality and functionality. Thermal insulation materials, heat insulation materials, and high-strength materials all belong to construction engineering materials.

[0003] Many construction engineering materials are affected by humid environments. For natural materials like wood, its cell walls contain a large number of hydroxyl (-OH) groups, which are hydrophilic. When the environmental humidity is high, wood absorbs moisture from the air, causing it to expand and deform. For example, wooden doors and windows used in a humid basement environment are likely to be difficult to open or close due to moisture absorption if not properly moisture-proofed. This also includes building thermal insulation materials such as rock wool, which may get damp under long-term high humidity environments or when directly in contact with water sources, although it has a certain degree of water repellency itself.

[0004] When drying existing building materials, most often the methods of sun drying or using hot air blowers are employed. During the process, materials need to be evenly placed in sequence. Placing a large number of building materials easily occupies a large amount of space, and the thermal energy utilization efficiency of hot air blowers is relatively low during the drying process. Therefore, the present invention aims to provide a construction pretreatment device for construction engineering materials to improve the deficiencies of the existing technology.

Specific embodiments

[0036] Next, in combination with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] Please refer to the attached Figure 1 - attached Figure 8 , the embodiments of the present invention provide a construction engineering material construction pretreatment device, including:

[0038] Chassis 1, on the top of the chassis 1 is installed a drying oven 2, which is used to store hot air flow to dry construction engineering materials;

[0039] Positioning cylinder 3, which is installed at the front of the drying oven 2, and at the upper side of its end is provided a feeding port for materials to enter the inside of the drying oven 2;

[0040] Feeding conveyor 4, which is installed at the front part of the top of the chassis 1, and is used to transport the construction engineering materials to be dried to the feeding port;

[0041] The overturning conveying mechanism 5 is arranged inside the drying box 2 and is used to perform multi-sided overturning processing on the construction materials during drying. The overturning conveying mechanism 5 includes a hanging frame 501 and two through-slot conveyors 502. The hanging frame 501 is fixedly installed on one side of the top inside the drying box 2.

[0042] One of the slot conveyors 502 is installed horizontally on the upper inner wall of the positioning cylinder 3 through a mounting rod, and the other slot conveyor 502 is installed in an inclined state on the lower inner wall of the positioning cylinder 3 through a mounting rod. The slot conveyor belt used by the slot conveyor 502, that is, the conveyor belt is provided with a plurality of long slots, which can allow airflow to pass through, so as to perform double-sided drying treatment on the material;

[0043] A reversing conveyor belt 503 is installed in the middle of the front side of the hanging frame 501, which is used to receive the materials conveyed by the upper slot conveyor 502, and then convey them to the lower slot conveyor 502 after they are turned over.

[0044] The overturning conveying mechanism 5 also includes a discharge conveyor 504 fixedly installed at the bottom end of the drying box 2, which is used to convey the dried materials to the discharge port opened at the rear side of the bottom of the drying box 2. The air outlet pipe of the hot air generator 7 passes through the rear part of the drying box 2 and the middle part of the hanging frame 501 in sequence;

[0045] During actual use, when the material enters the upper slot conveyor 502, the material will undergo a preliminary drying process, and when the material is conveyed to the end of the upper slot conveyor 502, it will fall on the swap conveyor belt 503. The surface of the swap conveyor belt 503 is a rubber surface with strong friction. When the block material contacts its surface, it will flip at a single point angle under the action of friction, and then enter the surface of the lower slot conveyor 502 for secondary drying. During this process, the airflow rotating cylinder 604 cooperates with the rotating airflow generated by the airflow slot plate 605 to evenly contact the surface of the material, thereby improving the drying process efficiency. After the material is dried, it falls on the discharge conveyor 504 and is transported to the discharge port at the bottom of the drying box 2, and then transported by the unloading conveyor 11 to the material collection box 12 for collection.

[0046] An airflow swirl mechanism 6, which is installed inside the positioning cylinder 3, is used to generate a rotating hot airflow to assist the material in drying;

[0047] For details, please refer to the attached Figure 5 -Attached Figure 6 The airflow swirl mechanism 6 includes a mounting plate 601 fixedly mounted at the bottom end of the hanging frame 501, a driving motor 602 is mounted on one side of the upper portion of the mounting plate 601 through a supporting frame, a bevel gear 603 is fixedly connected to the output end of the driving motor 602, and the bevel gear 603 is mounted on one end of the mounting plate 601 through a supporting bent plate.

[0048] The air flow swirling mechanism 6 further includes an air flow rotating cylinder 604 rotatably connected to the inner wall of the positioning cylinder 3. One side of the outer wall of the air flow rotating cylinder 604 is provided with a bevel gear ring. The bevel gear 603 is meshed and connected with the bevel gear ring. The inner wall of the air flow rotating cylinder 604 is equidistantly and fixedly installed with air flow groove plates 605 for promoting air flow disturbance.

[0049] By starting the operation of the drive motor 602 in the air flow swirling mechanism 6, the bevel gear 603 is driven to rotate by its output end. Under the meshing action, the bevel gear 603 drives the entire air flow rotating cylinder 604 to rotate. Through the air flow groove plates 605 installed inside the air flow rotating cylinder 604, turbulent flow can be generated inside the air flow rotating cylinder 604 to evenly swirl the hot air.

[0050] The hot air generator 7 is arranged at the rear of the drying box 2 and is used to generate hot air and convey it into the drying box 2.

[0051] One side of the top of the drying box 2 is fixedly installed with a reflux exhaust fan 8. A temperature sensor for monitoring the air flow temperature inside the drying box 2 is installed in the reflux exhaust fan 8. The air inlet of the reflux exhaust fan 8 is communicated with the front part of the positioning cylinder 3 through a reflux air pipe 10. A plurality of heat dissipation fins 9 are equidistantly and fixedly installed on the outer wall of the reflux air pipe 10.

[0052] The bottom rear side of the drying box 2 is fixedly installed with a blanking conveyor 11 for conveying the dried materials. After the materials are dried, they fall on the discharge conveyor 504, are conveyed to the discharge port at the lower part of the drying box 2, and then conveyed to the material collection box 12 by the blanking conveyor 11 to complete the collection. A material collection box 12 for receiving the dried materials is fixedly installed on one side of the chassis 1.

[0053] Working principle: In the actual use process of the present invention, the following working steps are specifically included:

[0054] Startup of the equipment: By starting the operation of the hot air generator 7, hot air flow is generated inside it and sent into the drying box 2 to fill the inside of the drying box 2 with hot air for preheating operation inside the box.

[0055] Generation of rotating air flow: By starting the operation of the drive motor 602 in the air flow swirling mechanism 6, the bevel gear 603 is driven to rotate by its output end. Under the meshing action, the bevel gear 603 drives the entire air flow rotating cylinder 604 to rotate. Through the air flow groove plates 605 installed inside the air flow rotating cylinder 604, turbulent flow can be generated inside the air flow rotating cylinder 604 to evenly swirl the hot air.

[0056] Feeding of construction materials: This device is applied to the drying of materials in various shapes, and mainly to the drying of block-shaped building materials, such as building wooden boards. During the actual use of the equipment, the materials are first transported to the feeding conveyor 4 by an external conveying device, then transported to the feeding port at the front of the positioning cylinder 3 by the feeding conveyor 4, and then enter the inside of the positioning cylinder 3;

[0057] Inversion and transportation operation of materials: When the materials enter the upper through-channel conveyor 502, a preliminary drying process will be carried out on the materials. In the present invention, the through-channel conveyor 502 uses a through-channel conveyor belt, that is, a plurality of long through-channels are opened on the conveyor belt, through which air can pass to perform double-sided drying treatment on the materials. When the materials are transported to the end of the upper through-channel conveyor 502, they will fall onto the swapping conveyor belt 503. The surface of the swapping conveyor belt 503 is a rubber surface with strong friction. When the block-shaped materials come into contact with its surface, they will be flipped at a single-point angle under the friction and then enter the surface of the lower through-channel conveyor 502 for secondary drying treatment. During this process, the rotating air flow generated by the air flow rotating cylinder 604 and the air flow trough plate 605 will evenly contact the surface of the materials, thereby improving the drying efficiency. After the materials are dried, they fall onto the discharging conveyor 504, are transported to the discharging port at the lower part of the drying box 2, and then transported to the material collection box 12 by the discharging conveyor 11 to complete the collection;

[0058] Temperature control during the working process: During the operation of this device, a temperature sensor is installed inside the reflux exhaust fan 8 to sense the temperature of the air flow inside the drying box 2. When the temperature is too high, the reflux exhaust fan 8 will start, extract the gas inside the drying box 2 through the reflux air pipe 10, and perform a certain cooling treatment on the gas through the plurality of heat dissipation fins 9 provided, and then draw it back into the inside of the drying box 2 to complete the temperature control operation. When the temperature inside the drying box 2 is insufficient, the temperature sensor inside the reflux exhaust fan 8 will send a signal to the hot air generator 7 to increase the air flow heating temperature, so that the drying temperature inside the drying box 2 is within a suitable range. At the same time, the reflux operation of the reflux exhaust fan 8 can reduce heat loss, and the thermal energy utilization rate of the equipment is good.

[0059] The present invention can realize automatic inversion of materials, improve the drying efficiency, and make the block-shaped materials automatically flip at a single-point angle during the transportation process by means of the friction generated by the rubber material on the surface of the swapping conveyor belt 503 to achieve secondary drying, so that all surfaces of the materials can be fully heated, saving labor operation costs while shortening the drying time and accelerating the pretreatment process of engineering materials, and having good application value.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
