Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a modular stacked energy-saving drying equipment and its installation method. Background Technology

[0002] In the field of material drying and processing, mesh belt drying equipment is widely used in food, chemical, and agricultural product industries due to its continuous operation and wide range of adaptable materials.

[0003] However, traditional mesh belt dryers mostly adopt an integrated structural design, with numerous components and a lack of standardized specifications. This results in cumbersome and time-consuming installation processes, poor compatibility between components, and difficulties in disassembly and replacement during later maintenance, leading to high maintenance costs. Furthermore, the wall panels of traditional equipment often use a spliced ​​structure, with large gaps at the joints and poor sealing performance. This not only causes hot air leakage and energy waste but also allows external dust and impurities to enter the equipment, contaminating materials and affecting product quality. To address the aforementioned problems of poor sealing performance, numerous components, and cumbersome installation in traditional dryers, this invention proposes a modular stacked energy-saving drying equipment and its installation method. Summary of the Invention

[0004] This invention provides a modular stacked energy-saving drying equipment and its installation method to solve the technical problems of poor sealing performance, numerous components, and cumbersome installation of traditional dryers.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A modular stacked energy-saving drying equipment includes a first-layer standard module, an upper-layer standard module, an air inlet module, a material outlet unit, a material spreading unit, a dehumidification unit, a transmission unit, and an insulation wall panel. Two sets of the first-layer standard modules are arranged side by side. Multiple sets of upper-layer standard modules are symmetrically stacked and fixed on top of the two sets of first-layer standard modules. Each set of first-layer standard modules and upper-layer standard modules includes a frame and a mesh belt arranged within the frame. The mesh belt is arranged in one layer in the two sets of first-layer standard modules, and the mesh belt is arranged in three layers in the multiple sets of upper-layer standard modules. The mesh belts in two adjacent sets of upper-layer standard modules are installed by rotating 180°. A transmission unit is provided on top of the two rows of upper-layer standard modules to drive the mesh belt of each layer. The dehumidification unit is located at the top of two rows of upper standard modules, and the air inlet module is located at one end of two sets of lower standard modules; the air inlet module draws in hot air, which passes through one set of lower standard modules and multiple sets of upper standard modules, and is discharged from the top dehumidification unit; The material spreading unit is arranged at one end of the top of the two upper standard modules and is used to spread material towards the mesh belts of the two upper standard modules. The material is conveyed from top to bottom through the mesh belts of multiple upper standard modules and one set of single-layer standard modules. The material discharging unit is arranged at one end of the two sets of single-layer standard modules and is used to output the material.

[0006] Optionally, a ladder is vertically arranged between the two rows of upper standard modules, and a fixing rod is fixed between each row of upper standard modules and between the two sets of first-layer standard modules. Insulated wall panels are attached to the outer periphery of the two sets of first-layer standard modules and the two rows of upper standard modules. The air inlet module is a variable diameter air duct joint set at the end of the first-layer standard module for corner connection to external heat delivery equipment. The dehumidification unit includes a shell mounted on the top of the two rows of upper standard modules and an exhaust joint on the shell for connecting to external exhaust equipment. A door panel is set in the middle of the shell, and the door panel is located directly above the ladder.

[0007] Optionally, each set of one-layer standard modules and the upper standard module also includes an active roller, a driven roller, and a non-powered roller. The active roller and the driven roller are rotatably installed at both ends of the frame. An active shaft seat for rotatably installing the active roller is provided on the outer wall of the frame. Each layer of mesh belt corresponds to a set of active rollers and driven rollers. The non-powered roller is used to support the upper surface of the mesh belt. An auxiliary roller is also rotatably installed in the frame to support the lower surface of the mesh belt.

[0008] Optionally, the first-layer standard module and the upper-layer standard module are provided with transfer plates at both ends, and the first-layer standard module and the upper-layer standard module are provided with integrated wall panels on both sides, the integrated wall panels being integrally formed; The integrated wall panel has a protrusion at the position corresponding to each layer of the mesh belt. The protrusion has an installation hole for installing the non-powered roller. The integrated wall panel above the protrusion is bent outward toward the frame to form a guide groove. The side of the mesh belt extends into the guide groove, leaving only a small gap between the side of the mesh belt and the guide groove to prevent the mesh belt from running off-center. The integrated wall panel above the guide groove is inclined outward toward the frame to form a slope plate with an inclination angle ranging from 70° to 80°. The integrated wall panel below the protrusion forms a recessed platform, and the auxiliary roller is assembled in the recessed platform.

[0009] Optionally, the unpowered roller is rotatably connected to two end shafts. Each end shaft has an anti-rotation plane and an end cap adapted to fit the end shaft. The end cap is fitted with a mounting hole, and a nut is threaded onto the end shaft. A flange is provided around the periphery of the end cap, and the minimum width of the end cap is greater than the cross-sectional diameter of the unpowered roller. During installation, the end cap is inserted into the mounting hole, and the flange abuts against the outer surface of the integrated wall panel. The end cap is fixed to the integrated wall panel by tightening the nut, thus installing the unpowered roller. For disassembly, simply remove the nut and detach the end cap from the mounting hole, allowing the unpowered roller to be pulled out, facilitating maintenance and assembly of the unpowered roller.

[0010] Optionally, a driven shaft seat is fixed to the side of the frame, and each driven roller corresponds to a pair of driven shaft seats, with the pair of driven shaft seats fixed at both ends of the side of the frame respectively; A pair of driven shaft seats have matching holes on their facing sides, and a pair of driven shaft seats have sliding grooves on their far sides. A sliding plate is slidably fitted in the sliding grooves, and the sliding plate slides along the conveyor belt direction. The end of the driven roller is connected to an end shaft two, which passes through the matching holes and is rotatably mounted on the sliding plate. An adjusting rod is threaded through the end of the driven shaft seat facing the center of the conveyor belt. The slag removal pipe abuts against the end of the sliding plate. By turning the adjusting rod, the sliding plate is pushed to slide, which is used to adjust the tension of the driven roller on the conveyor belt. The sliding groove is also provided with a scale, and the cross-section of the sliding groove is convex. A slag-cleaning pipe is arranged parallel to the driven roller on the side facing the center of the conveyor belt. The top of the slag-cleaning pipe facing the driven roller has a notch, and a scraper is provided at the lower edge of the notch. The scraper is inclined towards the driven roller and slides in contact with the driven roller. A retaining ring is provided at one end of the slag-cleaning pipe, and the retaining ring is fixed on one of the slide plates. A positioning hole is opened on the other slide plate. The end of the slag-cleaning pipe away from the retaining ring passes through the positioning hole. A spiral shaft is arranged axially inside the slag-cleaning pipe. An end shaft three is coaxially connected to the end of the spiral shaft facing the retaining ring. The end shaft three is rotatably installed on the corresponding slide plate. Gear one and gear two are respectively mounted on the end shaft two and end shaft three. Gear one and gear two mesh with each other. As the driven roller rotates with the mesh belt, the scraper scrapes the material residue on the surface of the driven roller into the cleaning pipe. The driven roller, through the transmission of gear one and gear two, synchronously drives the spiral shaft to rotate. The spiral shaft discharges the material residue in the cleaning pipe from one end of the cleaning pipe through the positioning hole. This material residue comes from the gaps in the mesh belt and falls onto the surface of the driven roller, preventing material residue from adhering to the surface of the driven roller and affecting the normal transmission of the mesh belt. The spiral shaft is composed of multiple spliced ​​parts, and each spiral shaft is provided with a threaded post and a threaded hole at both ends.

[0011] Optionally, the discharge unit includes a support 1, a support 2, and a chain plate. Support 1 and support 2 are respectively installed on opposite sides of two sets of single-layer standard modules. Support 3 is provided between support 1 and support 2 and is fixed between the two sets of single-layer standard modules. A shaft is rotatably installed inside support 1 and support 2. Discharge sprockets are coaxially mounted at both ends of the shaft. The chain plate passes through support 3 and is fitted onto the two shafts. Two discharge chains adapted to the discharge sprockets are provided on the inner surface of the chain plate. The end of support 2 away from the single-layer standard module passes through the support and a windproof curtain is provided inside support 2. A discharge motor for driving the shaft rotation is installed on support 2. Baffles are provided on both sides of the top of the chain plate. Discharge baffles are connected to the bottom of the baffles and are inclined toward the upper surface of the chain plate. The baffles are fixed on support 1, support 2, and support 3. The material is conveyed and dried from top to bottom through multiple sets of upper standard modules and the inner mesh belt of a single standard module, and then falls onto the chain plate. It is then output from support two via the chain plate to achieve discharge. Support one and support two can be interchanged to change the discharge direction. Two sets of support one and support two can also be set, with support two placed on the opposite side of the two sets of single standard modules, that is, the discharge port is set in the middle of the equipment.

[0012] Optionally, the material spreading unit includes a material spreading track, a slide rail, and a material spreading belt. The material spreading track is installed at one end of the top of two rows of upper standard modules. The slide rail is slidably mounted on the material spreading track. Belt roller 1 and belt roller 2 are rotatably installed at both ends inside the slide rail. The material spreading belt is fitted on belt roller 1 and belt roller 2. A material spreading motor 1 for driving belt roller 1 to rotate is installed on the slide rail. A bracket is fixed in the middle of the material spreading track. The bracket is mounted on the slide rail and a feeding hopper is provided on the bracket. A wheel seat is fixed in the middle of the material spreading track. A material spreading motor is mounted on the wheel seat. A material spreading gear is mounted on the output shaft of the material spreading motor. A rack is fixed at the bottom of the outer wall of the slide rail. The rack teeth mesh with the material spreading gear. A wheel seat is fixed on the material spreading track. A pressure roller is rotatably mounted on the wheel seat. The pressure roller rolls in contact with the upper surface of the rack. Track wheels are rotatably mounted at both ends of the outer wall of the slide rail. The track wheels roll in cooperation with the material spreading track. This is used to achieve reciprocating and uniform material spreading on the top of the two upper standard modules. The direction of material falling is always the same as the direction of the material spreading belt and the slide rail.

[0013] A side box is provided on one side of the material laying track to house the motor cable chain. Multiple idler rollers (Roller 1 and Roller 2) are also installed inside the track. Roller 1 supports the upper surface of the material laying belt, while Roller 2 supports the lower surface. A scraper is also installed inside the track, and grooves are formed on the side wall of the track corresponding to the scraper. The scraper is used to remove material residue that falls into the gaps of the material laying belt; the residue is discharged from the grooves. Optionally, the transmission unit includes a frame, output sprockets, a main chain, a transmission sprocket, and a secondary chain. A pair of frames are fixed between the top ends of two rows of upper standard modules. The frames are equipped with a reducer and a main drive motor for transmission cooperation. The reducer has two output shafts, corresponding to the two rows of upper standard modules respectively. Each output shaft is fitted with an output sprocket. The end of the drive roller in each set of upper standard modules and each layer of standard modules is connected to a transmission shaft. Each transmission shaft is coaxially fitted with two transmission sprockets. The output sprockets are fitted with the main chain, and the transmission sprockets are fitted with the secondary chain. The output sprockets and main chain on one frame are connected in series from top to bottom with the drive rollers corresponding to the odd-numbered layers of the mesh belt via the transmission sprockets and secondary chain. The output sprockets and main chain on the other frame are connected in series from top to bottom with the drive rollers corresponding to the even-numbered layers of the mesh belt via the transmission sprockets and secondary chain. The two main drive motors on the pair of frames jointly control the multi-layer mesh belt transmission.

[0014] The beneficial effects of the above-described technical solution of the present invention are as follows: This application adopts a standardized design with a single standard module and an upper standard module. Each module can be mass-produced, and the number of upper standard modules can be flexibly increased or decreased according to actual drying output requirements. It has strong versatility, a simple installation process, and does not require complex assembly technology. The non-powered roller adopts a quick-installation structure with end caps and nuts, and the entire module does not need to be disassembled during disassembly and maintenance, which greatly reduces installation and maintenance costs and improves operation and maintenance efficiency.

[0015] This application adopts an integrated wall panel design, eliminating the gaps of traditional spliced ​​wall panels and significantly improving the sealing performance of the module. Simultaneously, an insulated wall panel is attached to the outer perimeter of the equipment, effectively reducing hot air leakage, improving the equipment's insulation effect, and reducing energy consumption. Furthermore, after entering from the air inlet module, the hot air passes sequentially through one standard module and multiple upper standard modules, ensuring full contact with the material and high hot air utilization. The guide grooves on the wall panel, in conjunction with the sides of the conveyor belt, leave only tiny gaps, effectively preventing conveyor belt deviation and material leakage. The non-powered rollers and auxiliary rollers support the upper and lower surfaces of the conveyor belt, preventing sagging and deformation and reducing wear. The tension of the conveyor belt can be flexibly adjusted via an adjusting rod, preventing slippage due to excessive looseness or breakage due to excessive tightness. In addition, the material residue on the surface of the driven roller is scraped off by the scraper and then automatically discharged by the screw shaft. This can remove the material residue on the surface of the driven roller in a timely manner without manual cleaning. It can avoid the failure of the mesh belt drive and chain breakage caused by the accumulation of residue due to untimely manual cleaning, ensure the continuous and stable operation of the equipment, and reduce the equipment failure rate.

[0016] The material spreading unit of this application adopts a reciprocating uniform material spreading design. The slide rail drives the material spreading belt to slide back and forth, so that the material is evenly spread on the mesh belt. The mesh belts of the two adjacent upper standard modules are installed with a 180° rotation, so that the material is turned over during the conveying process, ensuring that all sides of the material can be fully contacted with hot air, avoiding the problem of incomplete drying of the material in some areas, and improving the uniformity of material drying.

[0017] Compared with traditional mesh belt drying equipment, this modular stacked energy-saving drying equipment adopts a standardized design, integrated structure, and automatic slag removal structure, which solves the problems of poor sealing performance, material leakage, chain breakage, many parts, and complicated installation of traditional dryers. At the same time, it has the advantages of energy saving, high efficiency, convenient operation and maintenance, and strong adaptability. Attached Figure Description

[0019] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 27 As shown, an embodiment of the present invention provides a modular stacked energy-saving drying equipment, which adopts a standardized module design and is composed of a first-layer standard module 1, an upper-layer standard module 2, an air inlet module 3, a material outlet unit 4, a material spreading unit 5, a dehumidification unit 6, a transmission unit 7, and an insulation wall panel 8.

[0021] In this embodiment, two sets of standard modules 1 are arranged side by side. Multiple sets of upper standard modules 2 are symmetrically stacked and fixed on top of the two sets of standard modules 1, forming a structure of two rows of upper standard modules 2 and two sets of standard modules 1. This overall stacked design significantly saves equipment floor space and improves space utilization. A ladder 10 is vertically installed between the two rows of upper standard modules 2, facilitating maintenance and repair. Fixing rods 9, made of high-strength stainless steel, are used to connect and fix each row of upper standard modules 2 and between the two sets of standard modules 1, ensuring a secure connection between modules, improving the overall structural stability of the equipment, and preventing shaking or displacement during operation. Standardized production allows for flexible adjustment of the number of upper standard modules 2 according to actual drying needs, adapting to different material drying requirements. Installation and disassembly are convenient, and the system is highly versatile.

[0022] In this embodiment, the air inlet module 3 is located at one end of the two sets of single-layer standard modules 1. Specifically, it is a variable-diameter air duct connector located at the end of the single-layer standard module 1. It can achieve corner connection with external heat delivery equipment, which facilitates flexible adjustment of the air inlet direction according to the on-site installation space. Moreover, the variable-diameter structure can be adapted to hot air ducts of different specifications, improving the equipment adaptability.

[0023] In this embodiment, the dehumidification unit 6 is installed at the top of the two rows of upper standard modules 2, including a housing 601 mounted on the top of the two rows of upper standard modules 2 and an exhaust connector 602 on the housing 601. The exhaust connector 602 is used to connect to an external exhaust device to realize the rapid exhaust of hot and humid air inside the device. A door panel 603 is provided in the middle of the housing 601. The door panel 603 is located directly above the ladder 10, which makes it convenient for staff to open the housing 601 to inspect the internal components.

[0024] In this embodiment, each set of one-layer standard module 1 and upper-layer standard module 2 includes at least a frame 101, an integrated wall panel 102, and a mesh belt 106 disposed within the frame 101. The material spreading unit 5 is arranged at one end of the top of the two rows of upper-layer standard modules 2 and is used to spread material toward the mesh belt 106 on the two uppermost sets of upper-layer standard modules 2. The material discharging unit 4 is arranged at one end of the two sets of one-layer standard modules 1 and is used to output the dried material. The transmission unit 7 is disposed at the top of the two rows of upper-layer standard modules 2 and is used to drive the transmission of each layer of mesh belt 106 to realize continuous material conveying.

[0025] In the two sets of single-layer standard modules 1, the mesh belt 106 is arranged in only one layer. In the multiple sets of upper-layer standard modules 2, the mesh belt 106 is arranged in three layers. In the two adjacent sets of upper-layer standard modules 2, the mesh belt 106 is installed by rotating 180°. This staggered arrangement allows the material to fully contact the hot air during the downward conveying process, extending the drying time of the material, improving the drying uniformity and drying efficiency, and making full use of the hot air to achieve energy saving. A sampling port 109 is provided at the top of the integrated wall panel 102 for sampling the material conveyed in each set of upper-layer standard modules 2.

[0026] Furthermore, the outer periphery of the two sets of single-layer standard modules 1 and the two rows of upper-layer standard modules 2 is covered with thermal insulation wall panels 8. The thermal insulation wall panels 8 are made of polyurethane insulation material and are tightly fitted with the module frame 101 and the integrated wall panel 102 without obvious gaps, which effectively improves the sealing performance and thermal insulation effect of the equipment, reduces hot air leakage, and reduces energy consumption.

[0027] In a further embodiment, each set of standard module 1 and upper standard module 2 includes a frame 101, an integrated wall panel 102, an active roller 103, a driven roller 104, a non-powered roller 105, a mesh belt 106, an active shaft seat 107, a driven shaft seat 108, and an auxiliary roller 113. The integrated wall panel 102 adopts an integrated molding design, which effectively eliminates splicing gaps compared to traditional spliced ​​wall panels, greatly improves the sealing performance of the module, and reduces the number of parts, simplifying the installation process.

[0028] Furthermore, the driving roller 103 and driven roller 104 are rotatably mounted at both ends of the frame 101. A drive shaft seat 107 for the driving roller 103 is provided on the outer wall of the frame 101. The drive shaft seat 107 is made of cast iron, possessing good wear resistance and stability, ensuring the long-term stable rotation of the driving roller 103. Each layer of mesh belt 106 corresponds to a set of driving roller 103 and driven roller 104. The mesh belt 106 is fitted onto the driving roller 103 and driven roller 104, and is driven by the driving roller 103 to achieve transmission. The driven roller 104 provides auxiliary support and guidance, preventing the mesh belt 106 from deviating. Multiple unpowered rollers 105 are provided, distributed between the driving roller 103 and the driven roller 104, to support the upper surface of the mesh belt 106, preventing the mesh belt 106 from sagging or deforming due to the weight of the material, and ensuring stable material conveying; an auxiliary roller 113 is also rotatably installed inside the frame 101, arranged below the mesh belt 106, to support the lower surface of the mesh belt 106, further improving the stability of the mesh belt 106 transmission, reducing the wear of the mesh belt 106, and extending the service life of the mesh belt 106.

[0029] Furthermore, both ends of the first-layer standard module 1 and the upper-layer standard module 2 are equipped with transfer plates. The transfer plates are designed with an inclination to facilitate the smooth drop of materials from the upper module's mesh belt 106 onto the lower module's mesh belt 106, preventing splashing and accumulation of materials during the drop process and ensuring continuous material conveying.

[0030] Furthermore, a boss 110 is provided on the integrated wall panel 102 at the position corresponding to each layer of mesh belt 106. The boss 110 has a mounting hole 112 for mounting the unpowered roller 105. The integrated wall panel 102 above the boss 110 is bent towards the outside of the frame 101 to form a guide groove 111. The side of the mesh belt 106 extends into the guide groove 111, and only a small gap is left between the side of the mesh belt 106 and the guide groove 111. This structure can effectively prevent the mesh belt 106 from running off-center during transmission, and at the same time reduce the leakage of material from the side of the mesh belt 106.

[0031] Furthermore, the integrated wall panel 102 above the guide trough 111 is inclined outward towards the frame 101 to form a slope. The slope angle ranges from 70° to 80°. This angle design can effectively prevent materials from accumulating on the slope and ensure that the materials slide smoothly onto the mesh belt 106. The integrated wall panel 102 below the boss 110 forms a recess 114. The auxiliary roller 113 is assembled at the recess 114. The structural design of the recess 114 can limit the auxiliary roller 113 and prevent it from shifting after installation.

[0032] In this embodiment, the unpowered roller 105 is rotatably connected to two end shafts 116. An anti-rotation plane is provided on the end shaft 116 to prevent rotation during the rotation of the unpowered roller 105, ensuring stable support of the conveyor belt 106 by the unpowered roller 105. An end cap 115 is appropriately fitted onto the end shaft 116, fitting into the mounting hole 112. A nut 117 is threaded onto the end shaft 116. A flange 118 is provided on the periphery of the end cap 115. The minimum width of the end cap 115 is greater than the cross-sectional diameter of the unpowered roller 105, effectively preventing the end cap 115 from falling out of the mounting hole 112. When installing the unpowered roller 105, the end cap 115 is inserted into the mounting hole 112 on the boss 110, so that the flange 118 on the periphery of the end cap 115 abuts against the outer surface of the integrated wall panel 102. Then, by tightening the nut 117, the end cap 115 is tightly fixed to the integrated wall panel 102, thereby realizing the installation and fixation of the unpowered roller 105. When the unpowered roller 105 needs to be maintained or replaced, it is only necessary to remove the nut 117 and remove the end cap 115 from the mounting hole 112, and the unpowered roller 105 can be pulled out from the mounting hole 112. The entire installation and disassembly process is simple and convenient, without the need to disassemble the entire module, which greatly improves maintenance efficiency and reduces maintenance costs.

[0033] In a further embodiment, a driven shaft seat 108 is fixed to the side of the frame 101. Each driven roller 104 corresponds to a pair of driven shaft seats 108. The pair of driven shaft seats 108 are fixed at both ends of the side of the frame 101 for mounting the driven roller 104. The pair of driven shaft seats 108 have an adapter hole 203 on their facing side for the end of the driven roller 104 to pass through. The pair of driven shaft seats 108 have a sliding groove 212 on their far side. The sliding groove 212 has a convex cross-section. A sliding plate 209 is slidably embedded in the sliding groove 212. The sliding direction of the sliding plate 209 is along the conveying direction of the mesh belt 106. The sliding groove 212 is also provided with a scale 213 to facilitate the operator to accurately adjust the sliding distance of the sliding plate 209.

[0034] Furthermore, the driven roller 104 is connected to an end shaft 204, which is rotatably mounted on the slide plate 209 through the adapter hole 203. An adjusting rod 210 is threaded through one end of the driven shaft seat 108 facing the center of the mesh belt 106. The adjusting rod 210 abuts against the end of the slide plate 209. By turning the adjusting rod 210, the operator can push the slide plate 209 to slide along the slide groove 212, thereby driving the driven roller 104 to move, thereby adjusting the tension of the mesh belt 106 and preventing the mesh belt 106 from slipping or running off course due to being too loose, or from wearing out or breaking due to being too tight.

[0035] Furthermore, a slag-cleaning pipe 201 is arranged parallel to the driven roller 104 on the side facing the center of the mesh belt 106. The top of the slag-cleaning pipe 201 facing the driven roller 104 has a notch 214, and a scraper 215 is arranged at the lower edge of the notch 214. The scraper 215 is inclined towards the driven roller 104 and slides in contact with the driven roller 104. When the driven roller 104 rotates with the mesh belt 106, the scraper 215 can scrape the material residue adhering to the surface of the driven roller 104 into the slag-cleaning pipe 201, so as to avoid the accumulation of material residue on the surface of the driven roller 104 and affect the normal transmission of the mesh belt 106. A retaining ring 208 is provided at one end of the slag cleaning pipe 201, and the retaining ring 208 is fixed on one of the sliding plates 209. A positioning hole 211 is provided on the other sliding plate 209. The end of the slag cleaning pipe 201 away from the retaining ring 208 passes through the positioning hole 211. A spiral shaft 202 is arranged axially inside the slag cleaning pipe 201. The spiral shaft 202 is composed of multiple spliced ​​spiral shafts. Each spiral shaft 202 has a threaded post 216 and a threaded hole 217 at both ends, which facilitates flexible splicing according to the length of the slag cleaning pipe 201 and reduces the difficulty of processing and transportation. An end shaft 3 205 is coaxially connected to the end of the spiral shaft 202 facing the retaining ring 208. The end shaft 3 205 is rotatably mounted on the corresponding sliding plate 209. Gear 1 206 and gear 2 207 are respectively mounted on end shaft 2 204 and end shaft 3 205. Gear 1 206 and gear 2 207 mesh with each other.

[0036] When the driven roller 104 rotates, it drives the gear 206 to rotate via the second end shaft 204. The gear 206 drives the gear 207 to rotate, which in turn drives the spiral shaft 202 to rotate via the third end shaft 205. During the rotation of the spiral shaft 202, the material residue in the cleaning pipe 201 is discharged from the end of the cleaning pipe 201 through the positioning hole 211, realizing automatic slag removal without manual cleaning, reducing the labor intensity of workers, and avoiding equipment failure caused by the accumulation of material residue, thus ensuring continuous and stable operation of the equipment. The material residue on the surface of the driven roller 104 mainly comes from the material falling into the gaps of the mesh belt 106. The automatic slag removal mechanism can completely remove this part of the residue, ensuring the transmission stability of the equipment.

[0037] In a further embodiment, the discharge unit 4 includes a first support 401, a second support 402, a third support 406, a shaft 403, a chain plate 407, and a discharge motor 409. The first support 401 and the second support 402 are respectively installed on the surfaces of the two sets of single-layer standard modules 1 that are far apart from each other. The third support 406 is provided between the first support 401 and the second support 402. The third support 406 is fixed between the two sets of single-layer standard modules 1 and serves as a connection and protection function.

[0038] Furthermore, both support 1 (401) and support 2 (402) have rotatably mounted shafts 403. Discharge sprockets 410 are coaxially mounted at both ends of the shafts 403. Chain plates 407 pass through support 3 (406) and are fitted onto the two shafts 403. Two discharge chains 405, adapted to the discharge sprockets 410, are provided on the inner surface of the chain plates 407. Through the meshing transmission between the discharge sprockets 410 and the discharge chains 405, the chain plates 407 are rotated, realizing the conveying and output of materials. Support 2 (402) has a through-hole at the end furthest from the first-layer standard module 1, serving as the discharge port. Support 2 (402) has a baffle curtain 408 installed inside. The baffle curtain 408 reduces the leakage of hot air from the discharge port, lowering energy consumption, and also prevents external dust from entering the equipment. A discharge motor 409 for driving the shaft 403 to rotate is installed on support 2 402. The discharge motor 409 is a variable frequency motor, which can flexibly adjust the speed according to the material output speed requirements to adapt to different drying outputs. Baffles 404 are provided on both sides of the top of the chain plate 407. The bottom of the baffles 404 is connected to the discharge baffles 411. The discharge baffles 411 are inclined towards the upper surface of the chain plate 407. The baffles 404 are fixed on supports 1 401, supports 2 402 and supports 3 406 to prevent material from leaking during conveying on the chain plate 407 and to ensure that the material is smoothly output from the discharge port of supports 2 402.

[0039] After being dried, the material is conveyed from top to bottom through multiple sets of upper standard modules 2 and one set of lower standard modules 1 via mesh belts 106. It then falls from the end of the mesh belt 106 in the lower standard module 1 onto the chain plate 407. The discharge motor 409 drives the shaft 403 to rotate, and the shaft 403, through the discharge sprocket 410 and discharge chain 405, drives the chain plate 407 to rotate, thus discharging the material from the discharge port of support two 402. Furthermore, supports one 401 and support two 402 can be swapped according to on-site conditions to flexibly change the discharge direction. Additionally, two sets of supports one 401 and support two 402 can be installed, with support two 402 positioned on one side of the two sets of lower standard modules 1 facing each other, i.e., the discharge port is located in the middle of the equipment, further improving the equipment's adaptability.

[0040] In a further embodiment, the material spreading unit 5 includes a material spreading track 501, a slide rail 502, a material spreading belt 503, a material spreading motor 504, and a material spreading motor 512. The material spreading track 501 is mounted on one end of the top of two rows of upper standard modules 2. The slide rail 502 is slidably mounted on the material spreading track 501 and can slide back and forth along the material spreading track 501 to achieve reciprocating material spreading. Belt roller 515 and belt roller 516 are rotatably mounted at both ends inside the slide rail 502, respectively. The material spreading belt 503 is fitted onto belt roller 515 and belt roller 516. The material spreading motor 504 is mounted on the slide rail 502 to drive the belt roller 515 to rotate. The material spreading motor 504 drives the belt roller 515 to rotate, thereby driving the material spreading belt 503 to achieve material conveying and spreading.

[0041] Furthermore, a bracket 506 is fixed in the middle of the material spreading track 501. The bracket 506 is mounted on the slide rail 502. A feeding hopper 505 is installed on the bracket 506. The feeding hopper 505 is used to feed the material to be dried. The material falls through the feeding hopper 505 onto the material spreading belt 503, which then transports it to the uppermost mesh belt 106. A wheel seat 511 is fixed in the middle of the material spreading track 501. A material spreading motor 512 is installed on the wheel seat 511. A material spreading gear 508 is installed on the output shaft of the material spreading motor 512. A rack 509 is fixed at the bottom of the outer wall of the slide rail 502. The teeth of the rack 509 mesh downwards with the material spreading gear 508. The material spreading motor 512 drives the material spreading gear 508 to rotate. Through the meshing transmission between the material spreading gear 508 and the rack 509, the slide rail 502 is driven to slide back and forth along the material spreading track 501. A wheel seat 513 is fixed on the material laying track 501, and a pressure roller 514 is rotatably mounted on the wheel seat 513. The pressure roller 514 rolls in contact with the upper surface of the rack 509 to ensure stable meshing between the rack 509 and the material laying gear 508. Track wheels 510 are rotatably mounted at both ends of the outer side wall of the slide rail 502. The track wheels 510 roll in cooperation with the material laying track 501 to reduce the friction when the slide rail 502 slides, ensuring smooth sliding of the slide rail 502 and reducing energy consumption.

[0042] Furthermore, a side box 507 is provided on one side of the material laying track 501 to house the motor cable chain, preventing it from becoming tangled or worn, and ensuring the safety of the wiring for the first material laying motor 504 and the second material laying motor 512. Multiple idler rollers 517 and 518 are also installed inside the slide rail 502. Idler roller 517 supports the upper surface of the material laying belt 503, and idler roller 518 supports the lower surface of the material laying belt 503, preventing the material laying belt 503 from sagging or deforming due to the weight of the material, and ensuring stable transmission of the material laying belt 503. The slide rail 502 is also equipped with a scraper 520. A groove 519 is opened on the side wall of the slide rail 502 corresponding to the scraper 520. The scraper 520 is used to scrape off the material residue that falls into the slide rail 502 from the gap of the material belt 503. The residue is discharged from the groove 519 to avoid the accumulation of material residue affecting the normal transmission of the material belt 503. The slide rail 502 is equipped with a material baffle 521 that is inclined towards the upper surface of the material belt 503 to guide the material conveyed on the material belt 503.

[0043] When the material spreading unit 5 is working, the material spreading motor 1 504 drives the material spreading belt 503 for transmission, while the material spreading motor 2 512 drives the slide rail 502 to slide back and forth along the material spreading track 501. The material is put from the feed hopper 505 onto the material spreading belt 503, and then conveyed by the material spreading belt 503 to the mesh belt 106 of the two upper standard modules 2. This achieves reciprocating and uniform material spreading on the top of the two upper standard modules 2, ensuring that the material is evenly distributed on the mesh belt 106 and improving the drying uniformity. Moreover, the falling direction of the material is always the same as the forward direction of the material spreading belt 503 and the slide rail 502, which avoids splashing when the material falls and ensures the stability of the material spreading.

[0044] In a further embodiment, the transmission unit 7 includes a frame 701, a main drive motor 702, a reducer 703, an output sprocket 705, a main chain 706, a transmission sprocket 708, and a secondary chain 709. A pair of frames 701 are provided, respectively fixed between the top ends of two rows of upper standard modules 2. The frames 701 are welded from high-strength steel, providing a stable structure and effectively supporting each transmission component. Each frame 701 is equipped with a reducer 703 and a main drive motor 702 that cooperate with each other. The main drive motor 702 is a variable frequency motor, allowing for flexible speed adjustment according to material conveying speed requirements. The reducer 703 reduces the output speed of the main drive motor 702, increases the output torque, and ensures stable drive. The reducer 703 has two output shafts 704, which correspond to two rows of upper standard modules 2 respectively. Each output shaft 704 is fitted with an output sprocket 705. The end of the drive roller 103 in each set of upper standard modules 1 and upper standard modules 2 is connected to a drive shaft 707. Each drive shaft 707 is coaxially fitted with two drive sprockets 708.

[0045] Furthermore, a main chain 706 is mounted on the output sprocket 705, and a secondary chain 709 is mounted on the drive sprocket 708. On one frame 701, the output sprocket 705 and main chain 706 are connected in series from top to bottom with the drive sprocket 708 and secondary chain 709 to the corresponding drive rollers 103 of the odd-numbered layers of mesh belts 106. On the other frame 701, the output sprocket 705 and main chain 706 are connected in series from top to bottom with the drive sprocket 708 and secondary chain 709 to the corresponding drive rollers 103 of the even-numbered layers of mesh belts 106. Two main drive motors 702 on a pair of frames 701 jointly control the transmission of the multi-layer mesh belts 106, ensuring that all mesh belts 106 travel at the same speed, thus achieving stable material conveying.

[0046] Furthermore, a guide post 710 is rotatably mounted on the drive shaft seat 107 on one side of the transmission sprocket 708. The secondary chain 709 is wrapped around the guide post 710 and fitted onto the transmission sprocket 708 to press the secondary chain 709 tight and prevent it from loosening and falling off.

[0047] When the transmission unit 7 is working, the main drive motor 702 starts, and after being reduced in speed by the reducer 703, the output shaft 704 drives the output sprocket 705 to rotate. The output sprocket 705 drives the transmission sprocket 708 to rotate through the main chain 706. The transmission sprocket 708 drives the drive roller 103 to rotate through the transmission shaft 707. The drive roller 103 drives the mesh belt 106. The drive rollers 103 of each layer of mesh belt 106 are driven by the transmission sprocket 708 and the secondary chain 709, thereby realizing the synchronous transmission of all layers of mesh belt 106, ensuring that the material passes through each layer of mesh belt 106 from top to bottom to complete the drying process.

[0048] This embodiment also provides a modular stacked energy-saving drying equipment installation method, including the following steps: Step 1, Pre-installation preparation: Inventory all equipment components, including first-layer standard module 1, upper-layer standard module 2, air inlet module 3, material discharge unit 4, material spreading unit 5, dehumidification unit 6, transmission unit 7, insulation wall panel 8, fixing rod 9, and ladder 10.

Step 2, Installation of Standard Module 1: Place two sets of Standard Module 1 side by side on the installation reference line according to the preset spacing. Adjust the level of Standard Module 1 using a level to ensure that the two sets of Standard Module 1 are at the same height and have aligned end faces. After adjustment, use expansion bolts to fix the frame 101 of Standard Module 1 to the installation base to prevent displacement during equipment operation. The spacing between fixing points should be controlled between 1.2 and 1.5m to ensure a firm fixation. Step 3, Stacking and installing the upper standard module 2: On top of the two sets of one-layer standard modules 1, symmetrically stack the first layer of upper standard modules 2, adjust the position of the upper standard modules 2 to ensure that the upper standard modules 2 are aligned with the frame 101 of the first-layer standard modules 1 and the integrated wall panel 102 is attached without any offset; use bolts to fix the bottom of the upper standard modules 2 to the top of the first-layer standard modules 1, with no less than 4 fixing bolts on each side and evenly distributed. Following the above method, stack the remaining upper standard modules 2 in sequence to form two rows of upper standard modules 2 structure. In the two adjacent sets of upper standard modules 2, the mesh belt 106 is rotated 180° to ensure that the material conveying direction meets the design requirements; Step 4, Installation of fixing rod 9 and ladder 10: Fixing rod 9 is connected and fixed between each row of upper standard modules 2 and between two sets of lower standard modules 1 using bolts. The two ends of fixing rod 9 are tightly fitted to frame 101. Tighten the bolts to ensure that each module is connected as a whole, improving the structural stability of the equipment. Ladder 10 is installed in the vertical gap between the two rows of upper standard modules 2. Ladder 10 is fixed to the frame 101 of the lower standard module 1 and each upper standard module 2. After installation, ladder 10 must be perpendicular to the ground. Step 5, Installation of Transmission Unit 7: Fix a pair of frames 701 between the top ends of the two rows of upper standard modules 2. The frames 701 are fixed to the frame 101 of the upper standard module 2 with bolts, ensuring that the frames 701 are installed flat and firmly; install the reducer 703 and the main drive motor 702 on each frame 701, adjust the position of the reducer 703 and the main drive motor 702 to ensure smooth transmission and firm fixation; fit the output sprocket 705 onto the reducer 703. On the output shaft 704 of 3, the transmission sprocket 708 is mounted on the transmission shaft 707 of each layer of drive roller 103, and then the main chain 706 and the auxiliary chain 709 are mounted respectively. The main chain 706 and the auxiliary chain 709 of one frame 701 are connected in series with the drive roller 103 corresponding to the odd-numbered layers of mesh belt 106, and the main chain 706 and the auxiliary chain 709 of the other frame 701 are connected in series with the drive roller 103 corresponding to the even-numbered layers of mesh belt 106. The chain tension is adjusted to prevent the chain from loosening or falling off. Step 6, Installation of Discharge Unit 4: Install Support 1 401 and Support 2 402 on opposite sides of the two sets of single-layer standard modules 1, respectively, and secure them firmly with bolts; Install Support 3 406 between Support 1 401 and Support 2 402, and fix Support 3 406 between the two sets of single-layer standard modules 1, ensuring that Support 1 401, Support 2 402, and Support 3 406 are installed flat; Rotate and install Shaft 4 inside Support 1 401 and Support 2 402. 03. Install discharge sprockets 410 at both ends of shaft 403, and pass chain plates 407 through support three 406 and install them on the two shafts 403, so that the discharge chain 405 and the discharge sprockets 410 are adapted to mesh; install windproof curtain 408 in support two 402, install discharge motor 409 on support two 402 and connect it to shaft 403; install baffles 404 and discharge baffles 411 on both sides of the top of chain plates 407, and ensure that baffles 404 are fixed firmly to prevent material leakage. Step 7, Installation of the material spreading unit 5: Place the material spreading track 501 at one end of the top of the two upper standard modules 2, and fix the material spreading track 501 to the frame 101 of the upper standard module 2 with bolts, ensuring that the material spreading track 501 is installed flat and level; slide the slide rail 502 onto the material spreading track 501, and rotate the track wheel 510 to both ends of the outer wall of the slide rail 502, ensuring smooth rolling contact between the track wheel 510 and the material spreading track 501; install belt roller 1 515, belt roller 2 516, idler roller 1 517, idler roller 2 518 and scraper 520 inside the slide rail 502, and install the material spreading belt 503. Motor 504 is connected to belt roller 515; bracket 506 and feed hopper 505 are installed in the middle of the laying track 501; wheel seat 511, laying motor 512 and laying gear 508 are installed on the laying track 501; rack 509 is installed at the bottom of the outer side wall of slide rail 502 to ensure smooth meshing between laying gear 508 and rack 509; wheel seat 513 and pressure roller 514 are installed on the laying track 501 to make pressure roller 514 roll contact with the upper surface of rack 509; side box 507 is installed on one side of the laying track 501 to store motor drag chain. This step can be carried out simultaneously with step four, the installation of fixing rod 9 and ladder 10. Step 8, Installation of Air Inlet Module 3 and Dehumidifier Unit 6: Install the air inlet module 3 and the reducing duct connector at one end of the two sets of single-layer standard modules 1. Adjust the angle of the air inlet module 3 to match the duct of the external heat delivery equipment. Use flange connection for fixation and add sealing gaskets at the connection to prevent hot air leakage. Place the housing 601 of the dehumidifier unit 6 on top of the two rows of upper standard modules 2. Adjust the position of the housing 601 to ensure that the door panel 603 in the middle of the housing 601 is directly above the ladder 10. Use bolts to fix the housing 601 to the frame 101 of the upper standard module 2. Then install the exhaust connector 602 on the housing 601, ensuring that the exhaust connector 602 is aligned with the duct of the external exhaust equipment and is firmly connected. Step 9, Installation of Insulation Wall Panel 8: Attach the insulation wall panel 8 to the outer periphery of the two sets of first-layer standard modules 1 and the two rows of upper-layer standard modules 2. The insulation wall panel 8 should be tightly fitted with the frame 101 and the integrated wall panel 102 without any obvious gaps. Fill any gaps with sealant to ensure sealing performance. The insulation wall panels 8 are connected by bolts, and the joints should be flat to avoid protrusions or looseness, ensuring insulation effect and preventing hot air leakage. Step 10, Installation and Commissioning: Check that all components are securely installed and smoothly connected. Start each unit motor and perform no-load commissioning. Check that the mesh belt 106 drive, the material spreading belt 503 reciprocating motion, the chain plate 407 conveying, and the automatic slag removal mechanism are operating normally. Check that the hot air circulation and dehumidification are smooth. After successful commissioning, conduct a load test run and observe the material spreading, conveying, and drying effects. Fine-tune the operating parameters of each unit according to the actual situation to ensure that the equipment achieves the designed drying effect. Installation is now complete.

[0049] The modular stacked energy-saving drying equipment provided by this invention operates as follows: During the material spreading process, the spreading motor 504 and spreading motor 512 of the spreading unit 5 are started. Spreading motor 504 drives belt roller 515 to rotate, which in turn drives the spreading belt 503. Spreading motor 512 drives spreading gear 508 to rotate. Through the meshing transmission between spreading gear 508 and rack 509, the slide rail 502 is driven to slide back and forth along the spreading track 501. The material to be dried is put into the feeding hopper 505. The material falls from the feeding hopper 505 onto the spreading belt 503, which then conveys it to the mesh belt 106 of the two upper standard modules 2, achieving reciprocating and uniform spreading and ensuring that the material is evenly distributed on the mesh belt 106.

[0050] Furthermore, during the material conveying process, the two main drive motors 702 of the transmission unit 7 are started. After being reduced in speed by the reducer 703, the main drive motors 702 drive the output sprocket 705 on the output shaft 704 to rotate. The output sprocket 705 drives the transmission sprocket 708 to rotate through the main chain 706. Then, through the cooperation of the secondary chain 709 and the transmission sprocket 708, the drive roller 103 is driven to rotate through the transmission shaft 707. The drive roller 103 drives the mesh belt 106. Among them, one frame 701 drives the odd-numbered layers of mesh belts 106, and the other frame 701 drives the even-numbered layers of mesh belts 106. All mesh belts 106 run synchronously. Under the drive of the mesh belts 106, the material passes through the mesh belts 106 of each upper standard module 2 from top to bottom, and finally enters the mesh belt 106 of the first standard module 1. The material conveying trajectory is Z-shaped, completing the conveying process. Because the mesh belts 106 of the two adjacent upper standard modules 2 are installed with a 180° rotation, the material will be flipped during the conveying process, ensuring that all sides of the material can fully contact the hot air and improve the uniformity of drying.

[0051] Furthermore, the air inlet module 3 is connected to the external hot conveying equipment, and the exhaust connector 602 of the dehumidification unit 6 is connected to the external exhaust equipment. The external hot conveying equipment and exhaust equipment are started, and hot air enters the two sets of single-layer standard modules 1 through the air inlet module 3, passing sequentially through the mesh belt 106 and material of the single-layer standard module 1, and then upwards into multiple sets of upper-layer standard modules 2, passing through each layer of mesh belt 106 and material, exchanging heat with the material, removing moisture from the material, and thus drying it. Under the action of the exhaust equipment, the hot and humid air is discharged outside the equipment through the exhaust connector 602 of the dehumidification unit 6, completing the hot air circulation drying. The insulation wall panel 8 around the equipment effectively reduces hot air leakage, improves insulation effect, and reduces energy consumption; the sealed design of the integrated wall panel 102 further reduces hot air leakage and the entry of external impurities, ensuring drying quality.

[0052] During material conveying, some fine materials may fall through the gaps in the mesh belt 106 and adhere to the surface of the driven roller 104. As the driven roller 104 rotates with the mesh belt 106, the scraper 215 on the cleaning pipe 201 scrapes the material residue from the surface of the driven roller 104 into the cleaning pipe 201. Simultaneously, the driven roller 104 drives the gear 206 to rotate via the end shaft 204, which in turn drives the gear 207 to rotate, thereby rotating the screw shaft 202. The screw shaft 202 discharges the material residue from the cleaning pipe 201 from one end of the cleaning pipe 201, achieving automatic slag removal and preventing the accumulation of material residue from affecting the normal transmission of the mesh belt 106 and the driven roller 104, thus reducing equipment malfunctions.

[0053] After being dried by the multi-layer mesh belt 106, the material falls from the end of the mesh belt 106 of the first standard module 1 onto the chain plate 407 of the discharge unit 4. The discharge motor 409 is started, driving the shaft 403 to rotate. The shaft 403, through the discharge sprocket 410 and the discharge chain 405, drives the chain plate 407 to rotate, outputting the material from the discharge port of support two 402, completing the discharge. Depending on the site conditions, the positions of support one 401 and support two 402 can be interchanged to adjust the discharge direction; alternatively, an additional set of support one 401 and support two 402 can be added, placing the discharge port in the middle of the equipment to improve its adaptability.

[0054] When the mesh belt 106 becomes loose or too tight, the operator can turn the adjusting rod 210 on the driven shaft seat 108 to push the slide plate 209 to slide along the slide groove 212, thereby moving the driven roller 104 and adjusting the tension of the mesh belt 106 to ensure stable transmission of the mesh belt 106. When maintenance is required on the unpowered roller 105, the nut 117 and end cover 115 can be removed to quickly pull out the unpowered roller 105. After maintenance, it can be reinstalled, making the operation convenient.

[0055] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
