Description

Technical Field

[0001] The utility model relates to the technical field of hotel linen drying, and more specifically, it relates to a drying device for hotel linen production. Background Art

[0002] Hotel linen generally refers to almost everything related to "cloth" in modern hotels, including hotel guest room bedding such as sheets, duvet covers, pillowcases, pillow cores, comforter cores, decorative fabrics, etc.; hotel bathroom products such as washcloths, face towels, bath towels, bathrobes, etc.; hotel restaurant textiles such as tablecloths, napkins, chair covers, etc.

[0003] In the production process of hotel linen, it is necessary to perform operations such as cleaning and disinfection on hotel linen, and after cleaning and spin-drying, the hotel linen needs to be dried. In the prior art, when drying hotel linen, a roller-type drying device is mostly used. Through the flipping of the roller, hot air flows through the middle of the hotel linen to achieve the drying of the hotel linen.

[0004] However, with the roller flipping method, the hotel linen is stacked together. Although the ventilation effect of the air flow among the linen can be enhanced during the flipping process, the hotel linen still stacks together during the flipping process, which results in a poor effect of discharging the moisture in the hotel linen to the outside, thus affecting the drying effect of the hotel linen.

[0005] Moreover, with this roller flipping method, the hotel linen will stack together during the drying process, resulting in large wrinkles in the hotel linen after drying, and subsequent operations such as pressing and ironing are required, and the operation process is cumbersome.

[0006] In addition, in the prior art, during the drying process of the drying device for hotel linen production, most of the high-temperature waste gas generated is directly discharged to the outside. And these waste gases contain relatively high energy, and direct discharge is likely to cause waste of energy. Moreover, during the hot air drying process, it is necessary to heat the outside fresh air, and the temperature of the outside fresh air is relatively low, resulting in high energy consumption during the heating process.

Detailed implementation manners

[0033] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0034] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0035] In the present utility model, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms are not used to limit the present utility model.

[0036] Please refer to Figures 1-5 , a drying device for hotel linen production, including a conveying rack 1, a conveying mesh belt 2 is arranged on the conveying rack 1, a plurality of installation grooves 3 are evenly opened on the conveying mesh belt 2, installation racks 4 are arranged at the edge positions of the installation grooves 3, and multiple groups of clamping rollers 5 are symmetrically installed in the installation racks 4. An elastic connection structure is arranged between the clamping rollers 5 and the installation racks 4. Among them, the elastic connection structure includes a connecting rack 17. The clamping rollers 5 are rotatably installed on the connecting rack 17 through bearings, and a connecting spring 18 is arranged between the connecting rack 17 and the installation rack 4, and a limit telescopic rod 19 is arranged in cooperation with the connecting spring 18. In this way, the hotel linen can be conveyed through the conveying mesh belt 2, and during the conveying process, the drying of the hotel linen can be realized, thereby improving the drying efficiency of the hotel linen. During this process, one end of the hotel linen or the corners at each end can be clamped between the corresponding two clamping rollers 5. Under the action of the connecting spring 18, the two groups of clamping rollers 5 can clamp and fix the hotel linen, so that during the subsequent blowing and drying, the stability of the hotel linen on the conveying mesh belt 2 can be improved, and the situation that the hotel linen is randomly blown under the action of the hot air force can be avoided, and the sufficiency and uniformity of the hotel linen during drying can be improved;

[0037] Among them, the clamping force between every two clamping rollers 5 in each group is greater than the wind force of the hot air when using blowing and drying. This can make the hotel linen evenly laid on the conveyor belt 2, thereby avoiding the situation that there are many wrinkles in the hotel linen after drying is completed, improving the drying effect. And through the setting of the connecting spring 18, when the hotel linen is under the action of manpower, it can be more conveniently pulled out between the two groups of clamping rollers 5, improving the convenience of use.

[0038] In the present utility model, a blowing pipe 6 is arranged between the upper and lower belt surfaces of the conveyor belt 2. A plurality of blowing heads 7 are evenly arranged on the blowing pipe 6. An air flow heating structure is arranged at the air inlet end of the blowing pipe 6. The air flow enters the inside of the blowing pipe 6 through the air flow heating structure and is evenly blown out towards the top surface of the conveyor belt 2 through the blowing heads 7 on the blowing pipe 6, thereby realizing the hot air drying of the hotel linen located on the conveyor belt.

[0039] In the present utility model, a protective cover 8 is arranged on the top of the conveying frame 1. An air outlet pipe 9 is arranged on the protective cover 8. An air supply pipe 10 is arranged between the air outlet pipe 9 and the air inlet end of the air flow heating structure. An air flow drying structure is arranged on the air supply pipe 10. Among them, the air flow drying structure includes a spiral heat exchange pipe 11. A liquid overflow prevention pipe 12 is arranged at the tail end of the spiral heat exchange pipe 11 connected to the air supply pipe 10 and protruding downward. A liquid collection structure is arranged at the bottom end of the liquid overflow prevention pipe 12. The liquid collection structure includes a diversion pipe 13 arranged at the bottom end of the liquid overflow prevention pipe 12. A liquid collection box 14 is arranged at the bottom end of the diversion pipe 13. An air extractor 24 is arranged on the air outlet pipe 9. In this way, during the drying process of the hotel linen, the air flow is driven by the air extractor 24. Among them, inside the protective cover 8, the hot air flow generated during the drying process will be conveyed to the spiral heat exchange pipe 11 through the air outlet pipe 9. Since there is more steam in the hot air flow, when passing through the spiral heat exchange pipe 11, the water vapor in the air flow will condense into liquid due to the decrease in the external temperature, thereby separating from the gas and realizing the drying of the gas. And the remaining gas still has a relatively high temperature, so it is conveyed to the air flow heating structure through the air supply pipe 10 for further heating, and then conveyed to the blowing pipe 6 again for blowing hot air during the drying process of the hotel linen. In this way, the waste heat in the exhaust gas during the drying process of the hotel linen can be recycled, reducing the consumption of heat energy and saving energy.

[0040] And during this process, the condensed liquid generated in the spiral heat exchange pipe 11 can be diverted to the liquid collection box 14 through the diversion pipe 13 for collection, avoiding the situation that the condensed liquid accumulates in the air supply pipe 10 and affecting the air flow transportation, and at the same time improving the drying effect of the air flow.

[0041] Please refer to Figures 1-5 , as an implementation manner of the liquid collection box 14: A drain pipe 15 is arranged at the bottom end of the side wall of the liquid collection box 14, and a solenoid valve 16 is arranged on the drain pipe 15.

[0042] Specifically, the drain pipe 15 facilitates the discharge of the condensed liquid collected in the liquid collection tank 14 to the outside, and the solenoid valve 16 facilitates the opening and closing of the drain pipe 15.

[0043] Please refer to Figures 1-5 , as an implementation manner of the protective cover 8: shielding curtains 20 are provided at both ends of the protective cover 8.

[0044] Specifically, through the shielding curtain 20, the shielding of the feeding and discharging ports of the protective cover 8 can be realized, ensuring the drying efficiency of the hotel linen inside the protective cover 8.

[0045] Please refer to Figures 1-5 , as an implementation manner of the convection heating structure: the air flow heating structure includes a heating box 21, and an electric heating wire 22 is arranged inside the heating box 21.

[0046] Specifically, after the air flow enters the heating box 21, it is heated by the electric heating wire 22, and then conveyed to the air blowing pipe 6, which can provide hot air flow for the drying of hotel linen.

[0047] Please refer to Figures 1-5 , as an implementation manner of the air outlet pipe 9: a protective net 23 is arranged at one end of the air outlet pipe 9 connected to the protective cover 8.

[0048] Through the setting of the protective cover 8, the situation that foreign matters enter the inside of the air outlet pipe 9 can be avoided, preventing blockage and improving the blowing cleanliness.

[0049] In summary, when the overall equipment is in use:

[0050] Lay the hotel linen to be dried flat on the conveyor belt 2, and tuck the ends of the hotel linen into the corresponding clamping rollers 5. Under the action of the connecting spring 18, the two groups of clamping rollers 5 can clamp and fix the ends of the hotel linen, thereby improving the stability during subsequent blowing and drying;

[0051] After that, the hotel linen is conveyed by the conveyor belt 2, and the exhaust fan 24 is started. Under the action of the exhaust fan 24, the air flow can flow sequentially through the air outlet pipe 9, the spiral heat exchange pipe 11, the air supply pipe 10, the heating box 21 and the air blowing pipe 6. During this process, the air flow will be heated by the electric heating wire 22 in the heating box 21 and blown out evenly towards the hotel linen on the conveyor belt 2 through the air blowing heads 7 on the air blowing pipe 6, thereby realizing the drying of the hotel linen during transportation;

[0052] In the present utility model, since the hotel linen is laid flat on the conveyor belt 2, the moisture carried in the hotel linen can be fully blown out upwards, with good drying efficiency, so that the streamlined operation of the hotel linen during drying can be realized, improving the drying efficiency and drying effect of the hotel linen;

[0053] The flat laying method can also avoid the situation where hotel linens have many wrinkles after drying, which is caused by the existing roller drying method;

[0054] In this process, the water vapor in the drying process will move upward due to the increase in temperature and the negative pressure of the exhaust fan 24, and enter the air outlet pipe 9, and be transported to the spiral heat exchange tube 11 through the air outlet pipe 9. Since the external temperature of the spiral heat exchange tube 11 is relatively low, the airflow containing water vapor will exchange heat with the outside during the process of being transported in the spiral heat exchange tube 11, so that the water therein will condense and be guided to the collecting tank 14 through the guide pipe 13 at the position of the overflow prevention pipe 12, so that the exhaust gas in the drying process can be dried, which is convenient for the subsequent recycling of the exhaust gas.

[0055] Afterwards, the above steps are repeated to allow the high-temperature exhaust gas from which the water vapor has been removed to be transported back to the heating box 21 for heating, thereby reducing the energy consumed in heating the airflow when drying hotel linens and improving the energy-saving effect.

[0056] In all the schemes mentioned above, the connection between two parts can be selected according to the actual situation by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably considered to be welding. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents;

[0057] In all the schemes mentioned above, if there is no clear description, the operation of electrical components is controlled by the controller. Since the devices matched with the controller are common devices, their control principles and line connections are all well-known and mature technologies, and their electrical connection relationships and specific circuit structures are not described here.

[0058] In all the schemes mentioned above, the motor involved can be matched with a reducer if necessary. The connection structure and working principle between the motor and the reducer are existing well-known technologies, and the utility model will not elaborate on them.

[0059] Among all the solutions mentioned above, those involving the connection between solar panels and batteries can be equipped with necessary accessories such as inverters, battery charging controllers, cables, fuses, and brackets. Their control principles and line connections are all well-known and mature technologies, and their electrical connection relationships and specific circuit structures will not be described in detail here.
