Description

Technical Field

[0001] The present invention relates to the technical field of building material drying, in particular to drying equipment for building decoration materials. Background Art

[0002] The primary reason for drying building decoration materials is to improve their physical and mechanical properties, extend their service life, and ensure construction quality and effectiveness. Drying specifically impacts building decoration materials. First, it improves physical and mechanical properties: Drying significantly reduces the material's moisture content, thereby improving its physical and mechanical properties. Dried wood is lighter and stronger, less prone to deformation, cracking, or mold, thus extending its service life. Second, it ensures construction quality and effectiveness: Undried building decoration materials may contain high moisture content, which can lead to quality issues such as deformation and cracking after construction. Drying ensures that the materials remain stable after construction, avoiding these problems. Third, it prevents biological damage: Dried materials are less susceptible to biological damage such as mold and insect pests, thereby maintaining their excellent appearance and functionality. However, existing building decoration material drying devices have simple structures and typically utilize traditional electrically heated drying chambers. This method can easily cause accumulation of building decoration materials. Furthermore, the electric heating method has significant limitations, which can lead to uneven drying of building decoration materials, resulting in poor performance. Furthermore, traditional electric heating methods for drying building decoration materials, due to structural limitations, result in high energy consumption and irrational resource utilization, significantly increasing economic costs. Furthermore, there is a lack of effective screening methods for dried building decoration materials in the later stages, making it impossible to efficiently classify and utilize different particle sizes of building decoration materials, thus failing to ensure construction quality and improve construction technology requirements.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] It should be noted that, in the specific embodiments of the present invention, terms such as "first" and "second" and other relational terms that may appear are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, terms such as "include", "comprise" or any other variants thereof that may appear are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the phrase "including one" or other defined elements that may appear does not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0020] In the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "provided with" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0021] Example 1: Figures 1 to 9 As shown: A drying device for building decoration materials includes a box 1. In this embodiment, a customized box 1 with a special structure is used to optimize the spatial layout structure, providing a strong foundation for subsequent efficient and energy-saving material drying and recycling. The box 1 is vertically distributed and adopts a cylindrical structure as a whole. Figure 2 As shown: A feeding structure 2 is provided at the top of the box body 1. In a preferred embodiment, the feeding structure 2 includes a feeding chamber 21, a stirring element 22, and a waste heat utilization element 23. The feeding chamber 21 is arranged at the top of the box body 1, and can be fixed by welding. The top of the feeding chamber 21 is connected to a feeding pipe 17, and the bottom is provided with a discharging pipe 18. An electromagnetic switch valve 19 can also be provided on the feeding pipe 17 to realize start and stop control. There are two discharging pipes 18 symmetrically distributed on the left and right, and an electromagnetic switch valve 19 is also provided on the discharging pipe 18. A sealing plate 34 is also provided at the bottom end of the lowest filter screen 31. The purpose of providing the feeding pipe 17 is to facilitate the connection of external raw materials and realize automatic and convenient transportation. The purpose of providing two discharging pipes 18 is to correspond to the two chambers below. Since the two chambers are independently designed and separated, it is convenient to evenly transport the material to the corresponding discharging pipe 18, and then enter the drying chamber 12 below. The purpose of providing the sealing plate 34 is to block and intercept the material, preventing other materials from falling into the lower part. In other words, based on the multi-stage screening, it prevents the building decoration materials from entering the nozzle 5 below, and also facilitates the subsequent collection and reuse of the materials. Preferably, the front side of the box body 1 is also hinged with a box door, and a sealing strip is provided between the two to ensure the sealing effect of the inner cavity of the box body 1.

[0022] like Figure 2 and Figure 6As shown: In a preferred embodiment, the stirring member 22 is used to stir and disperse the raw materials in the feed chamber 21. Specifically, the stirring member 22 includes a stirring shaft 221, a stirring motor 222, and a stirring blade 223. The stirring shaft 221 is vertically distributed and rotatably arranged in the feed chamber 21, and bearings are provided at the connection between the stirring shaft 221 and the upper and lower walls of the feed chamber 21. An external thread is provided on the stirring shaft 221; the stirring motor 222 is fixedly installed above the feed chamber 21 through a bracket and is connected to the stirring shaft 221; with such a configuration, the stirring motor 222 adopts a servo-controlled motor, which is convenient for driving the stirring shaft 221 to perform forward and reverse motion. The stirring blade 223 maintains a threaded rotation connection with the stirring shaft 221 through a connecting ring; adjacent connecting rings are supported and connected by a connecting rod 224. A small diameter connecting rod 224 can also be set between the stirring blades 223 of adjacent layers. The purpose of this setting is to achieve a radial cutting effect of the small connecting rod 224 on the building decoration material during the rotation of the stirring blade 223, thereby improving the stirring, crushing and preheating treatment effect of the building decoration material.

[0023] The specific working principle is that after the construction raw materials enter the feed chamber 21, the staff turns on the stirring motor 222. The stirring motor 222 rotates forward, which drives the stirring shaft 221 to rotate clockwise, which in turn drives the connecting ring and stirring blades 223 to rotate as a whole and begin to move downward. The stirring motor 222 rotates reversely, which drives the stirring shaft 221 to rotate counterclockwise, which in turn drives the connecting ring and stirring blades 223 to rotate as a whole and begin to move upward. This creates a stirring effect on the building decoration materials, enhancing the effect of uniform mixing and breaking up the processing, thereby preventing the agglomeration of building decoration materials caused by accumulation, and providing favorable conditions for subsequent efficient drying.

[0024] like Figure 2As shown in the figure: In a preferred embodiment, the waste heat utilization component 23 is used to preheat the raw materials in the feed chamber 21 using the waste heat flow. Specifically, the waste heat utilization component 23 includes a second temperature probe 231, a waste heat pipe 232, and a waste heat blower 233. The second temperature probe 231 is located in the feed chamber 21; this arrangement allows for real-time monitoring of the temperature within the feed chamber 21. The waste heat pipe 232 is located between the feed chamber 21 and the drying chamber 12 and is also equipped with a butterfly valve 234. The waste heat blower 233 is located in the waste heat pipe 232, and the second temperature probe 231 is electrically connected to the waste heat blower 233 and the butterfly valve 234, respectively. Automated operation can be achieved through a PLC controller to ensure full utilization of waste heat while meeting the temperature requirements of building decoration materials. The specific operating principles and circuitry are common knowledge to those skilled in the art and will not be described in detail here. All power required for this embodiment is provided by connecting to an external power supply. A one-way valve is preferably installed on the waste heat pipe 232 to ensure that the air flows to the feed chamber 21 and prevent building decoration materials from entering.

[0025] The specific working principle is that the waste heat airflow after entering the drying chamber 12 to dry the building decoration materials still has a certain temperature. If it is discharged directly to the outside, it also needs to be cooled, which means that some resources will be wasted, resulting in an increase in economic costs. Therefore, the innovation of the present invention is to lead the waste heat airflow of the drying chamber 12 into the feeding chamber 21, so as to realize the initial stage of mixing of the building decoration materials, that is, to start preheating treatment. It can also further achieve an enhanced effect of the building decoration materials in the mixing stage, achieving the purpose of a qualitative leap. At the same time, the reuse of waste heat resources is also realized. The two-way comparison of one increase and one decrease greatly saves the use of heat resources. At the same time, the energy consumption utilization is increased by 35%, and the heat resources are saved by more than 20%, which effectively reduces the economic cost of production.

[0026] like Figure 2As shown in this embodiment, the interior of the housing 1 is divided into a drying chamber 12 and an aeration chamber 13, arranged vertically, by a baffle 11. Furthermore, the drying chamber 12 is divided into a left chamber 15 and a right chamber 16 by a vertically arranged fixing plate 14. The left chamber 15 is also equipped with a movable member 3, specifically comprising a filter 31, a carrier plate 32, and a transmission mechanism 33. The filter 31 is generally grooved, with one side movably mounted to the carrier plate 32. This arrangement allows the filter 31 to hold building and decorative materials of a certain particle size. After grading, the up-and-down vibration creates a flattened surface for the materials, facilitating subsequent efficient screening and drying. In a preferred embodiment, the filter 31 is arranged in a fan-shaped pattern when viewed from above. The drying chamber has a circular cross-section; this arrangement facilitates the subsequent flattening of building and decorative materials and the circulation of airflow for drying. It also facilitates efficient screening of building and decorative materials of varying particle sizes through the combined effects of airflow impact, up-and-down vibration, and deflection. The inner end of the filter screen 31 is connected to the carrier plate 32 via a connecting structure 6. Specifically, Figure 3 As shown: the connection structure 6 includes a spline 61, a fixing pin 62, a clamping column 63 and a clamping plate 64. The spline 61 is a plurality of splines arranged on one side of the filter screen 31 and provided with a through hole 65. A slot 66 adapted to the spline 61 is provided on the carrier plate 32. This arrangement facilitates the formation of a simple connection. The carrier plate 32 is also provided with a vertically distributed fixing groove 67 that communicates with the slot 66. The fixing pin 62 is matched with the fixing groove 67. The purpose of this arrangement is to achieve unified fixation of multiple filter screens 31 after simple installation and positioning. Fixation is achieved through the fixing pin 62, avoiding the time-consuming and labor-intensive problem of traditional bolt connection. The clamping column 63 is horizontally distributed and fixedly installed on one side of the carrier plate 32. The clamping plate 64 is an elastic plate with an L-shaped structure, and one end is fixedly connected to the fixing pin 62, and the other end is matched with the clamping column 63 through a clamping hole 68 provided on the clamping plate 64. The purpose of such a configuration is to achieve a fixed position of the fixing pin 62 , thereby ensuring the fastening stability of the connection between the filter screen 31 and the carrier plate 32 .

[0027] like Figure 7 As shown: In this embodiment, the filter screen 31 is distributed in multiple intervals up and down, and the mesh diameter of the filter screen 31 distributed from top to bottom tends to decrease gradually; the purpose of such a setting is to form a multi-level screening effect, while also achieving an effective grading effect of building decoration materials. After grading, it is more conducive to achieving uniform laying of materials, thereby achieving the purpose of improving drying efficiency and saving heat resources based on the unit volume of building materials. Figure 7As shown, the structure of the filter 31 is mainly composed of a mesh body and a mesh frame. The mesh body is located at the bottom, and the mesh frame is solid and distributed on the outer circle of the mesh body. The carrier plate 32 is vertically distributed and arranged on the fixed plate 14. The transmission structure 33 is used to drive the carrier plate 32 to move up and down to perform seismic screening operations. In a preferred embodiment, as Figure 8 As shown: the transmission structure 33 includes a connecting arm 331, a movable plate 332, a rack 333, a gear 334, a transmission shaft 335 and a transmission motor 336. There are multiple connecting arms 331, and they are all installed on one side of the carrier plate 32, and can be fixed by welding. A connecting groove 337 adapted to the movement of the connecting arm 331 is also provided on the fixed plate 14. The movable plate 332 is arranged in the inner cavity of the fixed plate 14 and is fixedly connected to one end of the connecting arm 331. The rack 333 is arranged on the movable plate 332, and the two can be fixed by bolt connection or welding. The transmission motor 336 is fixedly installed in the inner cavity of the fixed plate 14 through a bracket. The transmission shaft 335 is distributed front and back and is connected to the transmission motor 336; the gear 334 is sleeved and installed on the transmission shaft 335, and the gear 334 is kept in meshing transmission with the rack 333. The racks 333 and gears 334 are matched and spaced apart in three groups. The carrier plate 32 in the left chamber 15 and the carrier plate 32 in the right chamber 16 are kept in opposite vertical positions. The movable plate 332 is the same length as the carrier plate 32 and is greater than half the length of the fixed plate 14. The right chamber 16 and the left chamber 15 have the same structure, and the mesh diameter of the filter screen 31 in the right chamber 16 is smaller than the mesh diameter of the filter screen 31 in the left chamber 15. Figure 7 As shown, for example, the mesh diameter of the top filter 31 on the left side (left chamber 15) is larger than the mesh diameter of the top filter 31 on the right side (right chamber 16). This arrangement is intended to achieve the graded reuse of a wider range of building decoration materials, thereby increasing the application scenarios for building decoration materials of different particle sizes. For example, this embodiment preferably utilizes a design with three filters 31 in the left chamber 15 and three filters 31 in the right chamber 16. This allows the drying equipment to efficiently dry, collect, and reuse six different particle sizes of building decoration materials.

[0028] The specific working principle is that the building decoration materials after preheating can enter the drying chamber 12 through the discharge pipe 18. Then the building decoration materials will fall from top to bottom into the filter 31 with different mesh diameters. At the same time, the staff turns on the transmission motor 336. The transmission motor 336 can also use a servo-controlled motor to facilitate precise control of forward and reverse movement. When the transmission motor 336 starts to rotate forward, it will synchronously drive the transmission shaft 335 and the gear 334 to rotate clockwise. In the initial state, the two carrier plates 32 are one above and one below. As shown in the figure, the left carrier plate 32 is located at the bottom and the right carrier plate 32 is located at the top. Clockwise rotation of the gear 334 drives the corresponding rack 333 to move, specifically driving the left rack 333, movable plate 332, carrier plate 32, and filter 31 upward, and the right rack 333, movable plate 332, carrier plate 32, and filter 31 downward. This creates a vibrating sieve for the building and decorative materials, while also allowing the materials to be spread flat, providing a foundation for subsequent hot air drying. Conversely, reverse rotation of the drive motor 336 drives the left rack 333, movable plate 332, carrier plate 32, and filter 31 downward, and the right rack 333, movable plate 332, carrier plate 32, and filter 31 upward. The structural design of the present invention is reasonable, and the key point of innovation is that by combining multiple groups of screens and carrier plates 32, on the basis of forming multi-level screening, the flat spreading of building decoration materials can be achieved, which is beneficial to improving the drying effect of subsequent heat flow circulation impact, and further improving the uniformity of raw material spreading and drying efficiency; the multi-level screen mesh size setting can achieve greater drying and classification needs in a smaller space.

[0029] like Figure 2 As shown in this embodiment, the aeration chamber 13 is connected to an external heat source on one side and a high-pressure blower 4 on the other. The high-pressure blower 4 is connected to a control switch to achieve continuous high-pressure heat supply. Multiple nozzles 5 are evenly distributed on the baffle plate 11. The left chamber 15 is also equipped with a first temperature probe 151 electrically connected to the high-pressure blower 4. This first temperature probe 151 is used to monitor the drying temperature of the drying chamber 12 (i.e., the left and right chambers 15, 16) in real time. Control between the first temperature probe 151 and the high-pressure blower 4 is achieved via a programmable logic controller (PLC). The operating principle of this section is prior art and will not be further described. Specifically, the heat source enters the aeration chamber 13 via the high-pressure blower 4. The concentrated hot air flow is then ejected upward through the nozzle 5, creating an "axial" airflow drying effect on the building and decorative materials within the filter 31 above, enhancing the drying efficiency. The filter 31 is securely mounted within the chamber, preventing material from spilling out and achieving multi-stage separation.

[0030] In order to enhance the drying effect of the airflow in the chamber on the building decoration materials. In this embodiment, preferably, an airflow pipe 8 is also provided on the side wall of the box body 1, and the input end of the airflow pipe 8 leads to the gas-making chamber 13; an electromagnetic switch valve 19 is provided at one end of the airflow pipe 8 to realize airflow interruption control. The airflow pipe 8 is also provided with a plurality of evenly distributed nozzles 81, wherein one end of the nozzle 81 passes through the inner cavity wall of the box body 1 and faces the drying chamber. The specific working principle is that the heat source enters the gas-making chamber 13 through the high-pressure fan 4, the electromagnetic switch valve 19 on the airflow pipe 8 is opened, and then the hot air flow in the gas-making chamber 13 will pass through the airflow pipe 8 upward and through the nozzle 81 to eject the airflow to the building decoration materials of the corresponding height, thereby realizing a "radial" airflow drying effect on the building decoration materials in the filter 31. In this way, the double-impact airflow drying greatly improves the drying effect of the material.

[0031] This drying equipment utilizes waste heat to improve resource utilization, integrating preheating, drying, and screening into an optimized and upgraded system. Its compact overall structure saves space and can reduce the volume by over 30% compared to traditional drying equipment of the same heat rate. It also improves energy efficiency by 35%, conserving over 20% of thermal resources, and effectively reduces production costs. The highly efficient drying of building and decorative materials of varying particle sizes can meet the diverse construction requirements of various architectural and decorative scenarios, thus expanding its application scope.

[0032] Example 2: Based on Example 1, Figure 4 and Figure 9 The figure shows a drying device for building decoration materials. The left and right sides of the fixed plate 14 are flat. A deflection member 7 is provided at the lower end of the fixed plate 14. Specifically, the deflection member 7 comprises a deflection motor 71, a main wheel 72, a secondary shaft 73, and a secondary wheel 74. The deflection motor 71 is fixed to the baffle plate 11 via a bracket. The main wheel 72 is sleeved onto the output shaft of the deflection motor 71. The secondary shaft 73 is vertically arranged and fixedly connected to the fixed plate 14 at one end. The secondary wheel 74 is sleeved onto the secondary shaft 73, ensuring that the main wheel 72 and the secondary wheel 74 are aligned and mounted. The diameter of the secondary wheel 74 is larger than that of the main wheel 72. This arrangement is intended to achieve deceleration and act as a buffer for deflection. A first limit plate 75 and a second limit plate 76 are provided on one side of the baffle plate 11, symmetrically about the fixed plate 14, to ensure that the deflection angle of the fixed plate 14 ranges from -45 to 45 degrees.

[0033] The specific working principle is that when a worker turns on the deflection motor 71, the forward rotation of the deflection motor 71 drives the main wheel 72 to rotate synchronously. Under the action of the meshing transmission, the main wheel 72 drives the secondary wheel 74 and the secondary shaft 73 to rotate, thereby driving the fixed plate 14 and the filter 31 to deflect clockwise as a whole. In this embodiment, the fixed plate 14 is perpendicular to the connecting line between the main wheel 72 and the secondary wheel 74 as the starting zero point; clockwise deflection is the positive direction, and counterclockwise deflection is the negative direction. Thus, when the deflection motor 71 is reversed, the main wheel 72 is driven to rotate synchronously. Under the action of the meshing transmission, the main wheel 72 drives the fixed plate 14 and the filter 31 to deflect counterclockwise as a whole. With this arrangement, an innovative feature of this drying equipment lies in the addition of a deflection structure, which acts as a rocking force on the filter 31 and the building decoration materials, thereby enhancing the screening and efficient drying of the filter 31.

[0034] Example 3: Based on Example 2, Figure 2 and Figure 5The figure shows a drying device for building decoration materials. A high-pressure, sealed liquid storage chamber 9 is located at the bottom of the gasification chamber 13. Liquid ammonia is stored in this chamber. Liquid ammonia is easy to store and transport safely, and the conversion of liquid ammonia into ammonia gas (vaporized ammonia) primarily relies on a change in physical state. The key to converting liquid ammonia into ammonia gas is to provide energy (such as heat) or change pressure conditions, allowing the liquid ammonia molecules to overcome intermolecular forces and transition from liquid to gas. A common industrial method for this conversion is through a vaporization system. A typical process includes: Heating and vaporization: Liquid ammonia is heated in an evaporator using warm water (e.g., 40°C) to convert it into ammonia gas. The pressure is then stabilized in a buffer tank for use. Pressure regulation: Liquid ammonia is stored in a high-pressure container. When the pressure is released by a pressure reducing valve, some of the liquid ammonia vaporizes due to the sudden drop in pressure. Therefore, in this embodiment, a resistance wire 91 is also located in the liquid storage chamber 9. This arrangement, coupled with a control switch, enables the conversion of liquid ammonia into ammonia gas. A combustion chamber 10 is located between the gasification chamber 13 and the liquid storage chamber 9, providing the foundation for combustion. A gas pipe 101 is installed between the combustion chamber 10 and the liquid storage chamber 9, connected to a solenoid valve 19. This valve is normally closed and opens only when ammonia is needed. An air pipe 102, connected to the outside world, provides sufficient oxygen to the combustion chamber 10. A booster pump can also be installed on the air pipe 102 to allow more oxygen to enter, creating a favorable combustible environment. A combustion hood 103 is also mounted at the bottom of the combustion chamber 10 via a bracket. The innovation of this hood is derived from household gas hoods. This hood communicates with the gas pipe 101 and is used to deliver ammonia to the combustion hood 103. An electric ignition trigger 104 is also provided on the combustion hood 103 for starting the ignition. An exhaust pipe 105 is provided between the combustion chamber 10 and the gasification chamber 13, and the high-pressure blower 4 is installed on the exhaust pipe 105. Although a small amount of water vapor remains and is output after the combustion of ammonia, a sodium hydroxide filter bag can be provided on one side of the exhaust pipe 105 to filter the water vapor and prevent the water vapor after the combustion of ammonia from entering the drying chamber 12, thereby ensuring the drying effect.

[0035] The specific working principle is as follows: first, the staff starts the resistance wire 91 to heat, and the simply heated liquid ammonia is converted into ammonia gas. The electromagnetic switch valve 19 of the gas pipe 101 is opened, and the accumulated ammonia gas enters the combustion hood 103, while oxygen from the air pipe 102 also enters. In this way, the flammable conditions are met. The next step is to turn on the electric ignition trigger 104 to achieve ignition, continuously transport ammonia gas, and then achieve continuous combustion of ammonia. The high-pressure blower 4 is started, and a steady stream of hot air begins to enter the gasification chamber 13 from the combustion chamber 10, and then the building decoration materials in the drying chamber 12 are evenly and efficiently dried by airflow. An innovative point of this drying equipment is that ammonia is a pure green, pollution-free combustible gas. After combustion, it produces nitrogen rather than undesirable gases such as carbon monoxide or carbon dioxide, and it is easy to carry and store, which greatly improves the drying efficiency of the drying equipment and the reuse value of building decoration materials.
