Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drying equipment, in particular to a garment drying system integrating air energy heat pump, chain conveying and intelligent wind field regulation. BACKGROUND

[0002] Garment drying is a key link in the process of textile and garment manufacturing, washing and finishing, and its energy efficiency and drying uniformity directly affect production efficiency and product quality. At present, the mainstream drying equipment in the industrial field mainly includes static drying room and continuous tunnel dryer.

[0003] The static drying room usually uses electricity, gas or steam for direct heating, and clothes are placed in batches on the rack and sent into a closed space for drying. This method has the following significant shortcomings: first, the heat source conversion efficiency is low, and the energy consumption cost is high; second, the air flow organization in the room is usually poor, which easily causes drying dead angles and leads to uneven drying of clothes; third, garment drying is an intermittent operation, which has low drying efficiency and low automation level.

[0004] In order to improve the continuity of operation, a tunnel dryer using chain conveying has appeared. Although this type of dryer realizes the continuous entry and exit of clothes, it still has many limitations in practical application. For example, Chinese invention patent CN202110889097.6 discloses a garment processing device with fast drying function, which uses a ring-shaped conveying chain to hang clothes and realizes continuous drying. However, this device has the following shortcomings: first, its hot air system usually has a fixed air duct, and the direction and range of the air outlet cannot be adjusted, which cannot provide differentiated and precise air supply for different types of clothes (such as shirts, pants, dresses, etc.); second, the hung clothes lack effective turning or rotating mechanism during conveying, which leads to uneven heating of the windward and leeward surfaces of the clothes; third, the heat source still uses traditional electric heating or gas, which fails to fully utilize high-energy efficiency technologies such as air energy heat pump, and the operation energy consumption still has room for optimization; finally, the overall intelligence level of the system is insufficient, and it is difficult to dynamically adjust the drying strategy according to real-time working conditions.

[0005] Therefore, the existing drying scheme combined with chain conveying still needs to be improved in terms of drying uniformity, comprehensive utilization of energy and intelligent adaptive control of the process. It is of great practical value to develop a drying system that can cooperate with air energy heat pump for efficient heating, chain conveying for continuous operation, and realize dynamic and precise air supply and intelligent control.

DETAILED DESCRIPTION

[0021] In order to make the person skilled in the art better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0022] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments. Figures 1-9 The present application will be described in detail below with reference to the drawings and in combination with the embodiments. Embodiment 1

[0023] Embodiment 1 discloses an intelligent clothing drying system based on air energy heat pump and chain conveying, the main part of the intelligent clothing drying system includes an air energy heat pump unit 10, a drying room 20, a closed-loop conveying chain assembly 30, and a control cabinet 40 integrated with a control system inside.

[0024] The drying room 20 constitutes the main drying space of the system, and the left side wall is provided with a feeding port 201 and a discharging port 202 in parallel to realize the continuous feeding and discharging of clothes. In order to optimize the internal air flow organization and drying process of the drying room 20, a vertical partition plate 203 extending to the right is arranged between the two openings, and a horizontal partition plate 204 is connected to the upper end of the partition plate. This design separates the drying room 20 into an upper return air area and a lower drying area, and the return air area is convenient for collecting hot and humid exhaust gas. The vertical partition plate 203 further divides the drying area into parallel process sections and return sections, forming a nearly "U" shaped drying path, effectively prolonging the residence time of clothes in the effective drying area.

[0025] The closed-loop conveying chain assembly 30 is the carrier of the clothing conveying, which includes four chain wheels 301 and a closed-loop conveying chain 302 running around them. Among them, two chain wheels 301 are located on the left side outside the drying room 20, and are transversely aligned with the feeding port 201 and the discharging port 202 respectively, one of which is driven by a conveying power motor 303 to provide system running power, and the other two chain wheels 301 are installed at the right end of the horizontal partition plate 204, and then the conveying chain 302 is tensioned between the four chain wheels 301 to form a rectangular circulating path, realizing the circulating conveying of clothes.

[0026] A plurality of hanging assemblies 40 are installed on the closed-loop conveying chain 302 at equal intervals, and are used to hang clothes to be dried. The distance between adjacent hanging assemblies 40 is preferably 60-80 cm, so as to provide sufficient space for clothes to spread out and avoid mutual blocking to affect ventilation. Specifically, the hanging assembly 40 comprises a U-shaped piece 401 fixedly connected with the closed-loop conveying chain 302, and a vertically arranged rotating rod 402 is installed at the upper and lower ends of the U-shaped piece 401 through bearings, so that the rotating rod 402 can freely rotate relative to the U-shaped piece 401. A hanging ring piece 403 with a narrow hanging opening is connected to the lower end of the rotating rod 402, which design can make the clothes hanger hook not easy to rotate by itself after being clamped, and ensure the stability of the initial hanging state. The top of the rotating rod 402 is fixed with a first gear 404 for driving rotation in the return section, and then a pointed guide block 405 is further fixed on the rotating rod 402 and located between the hanging ring piece 403 and the bottom surface of the U-shaped piece 401, which functions to guide and limit the posture of the hanging assembly 40 in the forward section.

[0027] In order to stabilize the posture of clothes in the key drying area (forward section) to facilitate intelligent identification and accurate air supply, two guide plates 205 fixed by connecting rods 206 are symmetrically arranged in the forward section of the drying area. The distance between the two guide plates 205 is slightly greater than the thickness of the pointed guide block 405, and the end close to the feeding port 201 is expanded in an "eight" shape, so as to facilitate smooth entry of the pointed guide block 405. When the hanging assembly 40 enters the forward section along with the closed-loop conveying chain 302, the pointed guide block 405 is constrained to slide between the two guide plates 205, so that the entire hanging assembly 40 moves linearly with a fixed orientation, and the plane of the clothes always advances parallel to the vertical partition plate 203, thereby creating stable conditions for subsequent image recognition and directional air supply.

[0028] In order to realize intelligent drying, a CCD camera 50 is arranged on the drying room 20, and the lens thereof is aimed at the hanging clothes entering the area of the guide plate 205, so as to collect images of the clothes. The CCD camera 50 is electrically connected with an image processing module in the control cabinet 40. The processing module analyzes the collected images in real time through image recognition technology, judges the type (such as shirt, trousers, dress, etc.), contour and approximate thickness of the clothes, and generates differentiated control instructions accordingly, thereby providing a basis for subsequent dynamic air field adjustment.

[0029] The core air supply actuator is a dynamic air field adjusting mechanism 60 installed on the two side walls of the process section, i.e. the inner wall of the drying room 20 and the vertical partition 203. This mechanism aims to solve the problem of limited air flow coverage of fixed air ports and the inability to adapt to different clothes. It includes multiple section tubes 601 connected end to end through sealed bearings, connected into a linear communication pipe, and its transverse installation position corresponds to the area of the guide plate 205, ensuring coverage of the main drying area. Each section tube 601 has an air outlet slit 602 on one side facing the conveying chain path, and a second gear 603 is fixed on the outer circular surface of one end of the section tube 601. Corresponding to each second gear 603, a vertical linear slide rail 604 is fixed on the wall surface, and a sliding rack 605 that can slide up and down and is engaged with the second gear 603 is installed on the slide rail. The upper end of the sliding rack 605 is connected to a servo cylinder 606 driven by the control system in the control cabinet 40.

[0030] In operation, the control system controls the corresponding servo cylinder 606 to drive the sliding rack 605 to move up and down with a specific amplitude and frequency based on the clothes information identified by the CCD camera 50, and then drives the corresponding section tube 601 to reciprocate through the transmission of the gear and rack, so that the hot air blown out of the air outlet slit 602 of the section tube 601 forms a controllable swinging scan in the vertical plane. This design enables the hot air to dynamically track and fully cover the passing clothes profile, especially for long coats or dresses, enabling targeted sweeping air supply along the length direction, greatly improving drying uniformity and efficiency.

[0031] The source of hot air for the system is an air energy heat pump unit 10, which has the advantage of high efficiency and energy saving as a heat source. The air outlet end of the air energy heat pump unit 10 is connected to the total air pipe 101, which extends to the end of the drying area process section and is divided into two first branch pipes 102, which are respectively sealed and rotatably connected to the ends of the two dynamic air field adjusting mechanisms 60 to provide controllable hot air. At the same time, the other end of each row of section tubes 601 is sealed and rotatably supported on the wall of the drying room 20 or the vertical partition 203 through a bearing seat 607, ensuring structural stability and not interfering with rotation.

[0032] In order to achieve supplementary drying of clothes and promote overall uniform heating of clothes, another set of air supply and driving rotation mechanism is arranged at the return section of the drying zone. The total air pipe 101 is connected with the second branch pipe 103 at the position of the return section, the second branch pipe 103 is located directly below the conveying chain path of the return section, and a plurality of air outlet holes 1031 are arranged on the upper surface of the second branch pipe 103 in a spaced manner, hot air is blown upward to act on the clothes. At the same time, a straight rack 207 is fixedly installed on the lower surface of the horizontal partition plate 204 of the return section, when the hanging assembly 40 moves through this area, the first gear 404 on the hanging assembly 40 will engage with the straight rack 207, thereby forcibly driving the rotating rod 402 and the suspended clothes to continuously rotate around the vertical axis. The combination design of "rotation + bottom air supply" enables the clothes to continuously change the angle to receive the hot air during the return process, realizes uniform drying without dead angle, and makes up for the possible wind blind area in the process section.

[0033] Finally, the dehumidification inside the system is driven by the negative pressure fan 70, and the air extraction end of the negative pressure fan 70 is connected to the return air area above the drying room through the negative pressure suction pipe 701. In operation, the negative pressure fan 70 forms a stable negative pressure in the return air area, continuously extracts the humid hot air rising in the drying area, and ensures the necessary humidity discharge of the drying environment. Embodiment 2

[0034] Embodiment 2 discloses an intelligent garment drying system based on the technical scheme of embodiment 1 for energy saving optimization, which is mainly designed from two aspects of heat energy recovery in humid hot air flow and prevention of hot air leakage. The same parts as embodiment 1 are not described again.

[0035] In terms of heat energy recovery in humid hot air flow, a condenser 80 is additionally arranged on the pipeline of the negative pressure suction pipe 701, and the condenser 80 is installed outside the drying room 20. The air extraction end of the negative pressure fan 70 is connected to the air outlet side of the condenser 80, and the air outlet end is connected to the air inlet side of the air energy heat pump unit 10 through a pipeline. The working process is as follows: the high-temperature and high-humidity waste gas extracted from the return air area first passes through the condenser 80, a large amount of water vapor in the waste gas is condensed into water and discharged, and the latent heat of vaporization is released at the same time. Then, the air after dehumidification and cooling (still with residual temperature) becomes dry and medium-temperature air, which is then sent into the evaporator side of the air energy heat pump unit 10 by the negative pressure fan 70 for preheating. This design realizes the double recovery of sensible heat and latent heat in the waste gas, significantly reduces the heat absorption load of the air energy heat pump unit 10 from the environment air, and thus improves the overall energy efficiency ratio of the whole system.

[0036] In terms of preventing hot air from leaking outside, the drying room wall outside the feeding port 201 and the discharging port 202 is additionally provided with a pair of sealing sliding doors 90 controlled in linkage. The bottom of the two sealing sliding doors 90 is slidingly installed on the same fixed bottom rail 901. The sealing sliding doors 90 are both provided with a sliding door rack 902 on the side facing each other, and the two racks are arranged in central symmetry. Then, a motor seat 903 is arranged at the symmetrical center of the two sliding door racks 902, and an opening and closing motor 904 is installed on the motor seat 903, and a third gear 905 is arranged on the motor shaft of the opening and closing motor 904, which is in meshing engagement with the two sliding door racks 902. According to the beat of the conveying chain and the position of the hanging assembly, the operation of the opening and closing motor 904 is accurately controlled by the control system. When one of the hanging assemblies 40 outside the feeding port 201 reaches the feeding port 201, one of the hanging assemblies 40 inside the discharging port 202 also reaches the discharging port 202, at this time, the opening and closing motor 904 operates to make the two sealing sliding doors 90 move close to each other under the meshing transmission of the gear and rack, so that the feeding port 201 and the discharging port 202, which are originally sealed by the two sealing sliding doors 90, are smoothly opened; when the hanging assembly 40 moves through the feeding port 201 or the discharging port 202, the opening and closing motor 904 is reversely rotated to drive the two sealing sliding doors 90 to move away from each other, so as to seal the feeding port 201 and the discharging port 202 again. This intermittent synchronous opening and closing mechanism maximally reduces the leakage of hot air inside the drying room 20 and the invasion of cold air, ensures the stability of the temperature and humidity in the drying room 20, and further reduces the energy loss.

[0037] The above is only the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
