Description

Technical Field

[0001] The utility model relates to the technical field of washing industry, in particular to a tunnel washer with good energy-saving effect and a washing system thereof. Background Art

[0002] Our tunnel washing machine series, also known as "tunnel washers," utilizes water circulation and filtration technology to significantly reduce water and steam consumption compared to traditional washing machines, saving 50% in water, over 40% in electricity, and 60% in labor. Tunnel washers offer superior performance and exceptional reliability. Their bottom-feed design ensures safe and reliable linen transport. The combination of single and double drums, high-strength ribs, and an optimally proportioned conveyor and wash chamber volume deliver powerful mechanical force and superior cleanliness. Furthermore, the double drum design is only used where detergent addition is required, such as during heating and rinsing, reducing the number of mechanical components and maintenance workload.

[0003] The tunnel washer's washing principle is as follows: Each chamber washes simultaneously. Each section can operate according to different computer instructions, including pre-wash, main wash, rinse, and neutralization programs. Fabrics are conveyed simultaneously. After each washing cage has been washed for a set period of time, they are simultaneously conveyed to the next washing cage, moving from the first to the last chamber. After exiting the last chamber, they enter the press for dehydration. Fabric washing and dehydration occur simultaneously. Washed fabrics are fed into the first chamber and exit the last chamber into the dryer simultaneously. After dehydration, the fabrics are sent to the dryer for drying.

[0004] In the prior art, an integrated washing dragon is disclosed, which includes a recycled water system, a pre-wash mechanism, a main wash mechanism, a rinse neutralization mechanism, and a softening mechanism. The temperature in the third and fourth chambers of the main wash mechanism is increased by a heating component, and the wastewater is discharged in the eighth and ninth chambers. 30-50°C softened water is introduced into the 13th chamber of the rinse neutralization mechanism, and clean water is introduced into the 14th chamber of the softening mechanism. In the above process, the 8th and 9th chambers still contain a high amount of heat, which is directly discharged, resulting in a large amount of heat not being recovered, causing a waste of resources. At the same time, the softened water introduced into the 13th chamber needs to be heated, increasing the heating cost, while the clean water introduced into the 14th chamber is at room temperature, causing the fabric to alternate between high and room temperatures, which is not conducive to the further separation of unwashed additives or other impurities from the fabric.

[0025] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0027] In the description of the present invention, it should be understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be intermediate elements at the same time. On the contrary, when an element is said to be "directly" connected to another element, there are no intermediate elements.

[0028] See also Figure 1 , which is a preferred embodiment of the utility model and has a good energy-saving effect. It is used for washing fabrics. Specifically, the tunnel washer includes a washing body 10 and an energy-saving heating device connected to the washing body 10. The washing body 10 is used for washing fabrics, and the energy-saving heating device is used to recover heat from the washing body 10 and provide heat energy for the washing body 10.

[0029] The washing body 10 includes a pre-cleaning mechanism, a main cleaning mechanism, a rinsing and neutralizing mechanism, and a softening mechanism which are connected in sequence.

[0030] The pre-cleaning mechanism includes a first chamber and a second chamber. A first water supply pipe 11 is provided at the feed of the first chamber. During the cleaning process, main washing liquid and emulsifier are added to the first chamber, and emulsifier and alkaline auxiliary agent are added to the second chamber.

[0031] The main cleaning mechanism includes the third, fourth, fifth, sixth, seventh, eighth, and ninth chambers. A first air distributor (not shown) is located at the bottom of the fourth chamber, while a second air distributor (not shown) is located at the bottom of the fifth chamber. The first and second air distributors are each connected to an energy-saving heating device, which directly supplies high-temperature steam to the fourth and fifth chambers, heating them to the required temperature. The air distributors provide uniform heating. The steam outlets of these two air distributors are positioned downward, sideways, or upward. Optimally, they are positioned downward to avoid spraying and potentially damaging the fabric. During the cleaning process, alkaline additives and oxygen bleach are added to the third chamber. A second water supply pipe 12 and a first drain pipe 13 are located in the eighth chamber, while a third water supply pipe 14 and a second drain pipe 15 are located in the ninth chamber. Both the first and second drain pipes 13, 15 are connected to the energy-saving heating device to recover the heat energy contained in the discharged wastewater.

[0032] The rinse neutralization mechanism includes the tenth, eleventh, twelfth, and thirteenth chambers. The tenth chamber is equipped with a third drain pipe 16, a first return water tank 17 connected to the third drain pipe 16, and a first return water pump 18 connected to the first return water tank 17. The outlet of the first return water pump 18 is connected to the first water supply pipe 11 of the first chamber. Since the water temperature of this part is still relatively high, this part of the rinse water is transported to the first chamber for reuse. The thirteenth chamber is equipped with a fourth water supply pipe 19, which is connected to the energy-saving heating device to provide hot water of an appropriate temperature. The chambers in the rinse neutralization mechanism use countercurrent rinsing, that is, water flows countercurrently from the thirteenth chamber to the tenth chamber, and then is discharged from the tenth chamber. During the cleaning process, a neutralizer is added to the thirteenth chamber.

[0033] The softening mechanism includes the fourteenth, fifteenth, and sixteenth chambers. The fourteenth chamber is equipped with a fifth water supply pipe 20, a fourth drain pipe 21, a second return tank 22 connected to the fourth drain pipe 21, and a second return pump 23 connected to the second return tank 22. The fifth water supply pipe 20 is connected to an energy-saving heating device, which provides hot water at an appropriate temperature. This allows the fabrics in the thirteenth and fourteenth chambers to transition to a similar water temperature, further removing any additives or other impurities that have not been cleaned. The outlet of the second return pump 23 is connected to the second water supply pipe 12 of the eighth chamber, transporting this water to the eighth chamber for reuse. During the cleaning process, a softener or neutralizer is added to the fourteenth chamber. Both the fifteenth and sixteenth bins utilize a squeezing, dehydration, and drying process. The sixteenth bin is equipped with a fifth drain pipe 24, a third return water tank 25 connected to the fifth drain pipe 24, and a third return water pump 26 connected to the third return water tank 25. The outlet of the third return water pump 26 is connected to the third water supply pipe 14 of the ninth bin. The water squeezed from the sixteenth bin is collected by the third return water tank 25 and then transported to the ninth bin for reuse via the third return water pump 26. Since the water from the fourteenth and sixteenth bins still has a relatively high temperature and is not much different from the water temperature of the eighth and ninth bins, respectively, after mixing, it will not significantly affect the water temperature of the eighth and ninth bins. At the same time, by recycling the water from the fourteenth and sixteenth bins, the rinsed fabrics are further cleaned, which is beneficial for removing stains on the fabrics.

[0034] The energy-saving heating device includes an energy-saving recovery system and a heating system. The energy-saving recovery system includes a heat recovery heat exchanger 27, a heat storage tank 28, and a heat pump 29. The water inlet of the heat exchange end of the heat recovery heat exchanger 27 is connected to the softened water supply pipe, and the water outlet of the heat recovery heat exchanger 27 is connected to the heat storage tank 28. The hot water after heat exchange is stored in the heat storage tank 28 for later use. The water inlet of the heat supply end of the heat recovery heat exchanger 27 is connected to the connecting pipe of the first drain pipe 13 and the second drain pipe 15. The water outlet of the heat supply end of the heat recovery heat exchanger 27 is connected to the energy-saving recovery system. The excess heat energy of the wastewater is used to heat the refrigerant of the energy-saving recovery system for further heat recovery. The water outlet of the heat pump 29 is connected to the fourth water supply pipe 19 of the 13th warehouse and the fifth water supply pipe 20 of the 14th warehouse, respectively, providing clean hot water to these two warehouses for later cleaning.

[0035] The heating system includes a compressor 30, a condenser 31, a throttling expansion valve 32, a first evaporator 33, a second evaporator 34, and a blower 35. The heat exchange inlet of the condenser 31 is connected to the softened water supply pipe, while the steam outlet of the condenser 31 is connected to the first air distributor in the fourth tank and the second air distributor in the fifth tank, respectively, to provide them with high-temperature steam. The first evaporator 33 and the second evaporator 34 are arranged in parallel. The heat exchange inlet of the first evaporator 33 is connected to the heat supply outlet of the heat recovery heat exchanger 27. The heat exchange outlet of the first evaporator 33 is connected to a sewage treatment plant, where the sewage is discharged after treatment. The air inlet of the heat exchange end of the second evaporator 34 is connected to the blower 35, and the air outlet of the heat exchange end of the second evaporator 34 is used to be connected to the air supply duct, which can provide cooling air for production workshops, canteens, dormitories, etc. The heat energy of the first evaporator 33 is preferentially utilized for heat exchange, and then the corresponding heat exchange capacity of the second evaporator 34 is configured according to the inlet refrigerant temperature requirement of the compressor 30. If the cooling effect of the air supply duct is insufficient, other refrigeration equipment can be configured according to demand. It can be understood that the compressor 30, the condenser 31, the throttling expansion valve 32, and the first evaporator 33 are connected end to end to form a first heating cycle, and the compressor 30, the condenser 31, the throttling expansion valve 32, and the second evaporator 34 are connected end to end to form a second heating cycle. The heating cycle is filled with refrigerant, such as R245fa, R134a, R22, R142b, R515B, R1233zd, R141B, R407c, R410a, R32, etc., which can be used individually or in combination as needed, such as R22+R142b, R22+R245fa, R32+R515B, R32+R141B, etc., which will not be repeated here.

[0036] In the above embodiment, the temperature of the first chamber is 40°C-50°C; the temperature of the fourth chamber is 60°C-80°C; the temperature of the fifth chamber is 60°C-80°C; the temperature of the eighth chamber is 50°C-60°C; the temperature of the ninth chamber is 50°C-60°C; the temperature of the thirteenth chamber is 40°C-50°C; and the temperature of the fourteenth chamber is 40°C-50°C.

[0037] In another embodiment, the steam supply temperature of the steam outlet at the heat exchange end of the condenser 31 is 100°C-150°C. Preferably, the steam supply temperature of the steam outlet at the heat exchange end of the condenser 31 is 110°C-120°C to avoid the impact of high temperature on the fabric.

[0038] In other embodiments, if the water pressure in the confluence of the first and second drain pipes 13, 15 is insufficient to deliver water to the heat recovery heat exchanger 27 and the second evaporator 34, a water pump can be added to the confluence of the first and second drain pipes 13, 15 to increase the delivery force. If the water flow in other water supply pipes is insufficient (e.g., during startup), fresh softened water can be added to ensure normal operation of the device.

[0039] In this embodiment, the condenser 31, the heat recovery heat exchanger 27, and the first evaporator 33 are all shell-and-tube heat exchangers, while the second evaporator 34 is a spiral tube heat exchanger. A spiral tube heat exchanger is constructed by placing one or more spirally wound tubes within a shell. The refrigerant flows through the spiral tubes, while the air flows through the interior of the shell, exchanging heat through the walls of the spiral tubes to improve the heat exchange between the refrigerant and the air. Preferably, the condenser 31 employs a condensation-vaporization integrated device structure, allowing steam to be produced directly from a single device without the need for a superheater. The specific structure is prior art and will not be described in detail here.

[0040] The above equipment is equipped with control valves and detection instruments according to needs to monitor and control them so that they can provide appropriate temperature and related operations for washing.

[0041] The heating principle of the tunnel washer in this embodiment is:

[0042] The water discharged from the tenth bin is transported to the first bin for pre-washing the fabrics. The fabrics are washed sequentially from the first bin to the ninth bin according to the control program of the tunnel washer. In the fourth and fifth bins, the heat of the high-temperature refrigerant is exchanged through the condenser 31 to produce appropriate high-temperature steam, which is then transported to the fourth and fifth bins. The steam is then evenly sprayed through the air distributor to heat the water in the bins. When the fabrics are transported to the eighth and ninth bins, they are mixed with the water discharged from the fourteenth and sixteenth bins to wash the fabrics in the bins. The washed sewage is discharged through the drain pipe. The fresh / purified softened water is heated by the heat recovery heat exchanger 27 and then stored in the heat storage tank 28. The stored hot water is transported to the 13th and 14th bins as needed. The flow from the 10th to the 13th bins is countercurrent. The washing hot water is input from the water inlet pipe of the 13th bin to rinse the fabric in countercurrent and then flows out from the drain pipe of the 10th bin. A final rinse is performed in the 14th bin, and then the fabric is dehydrated using a pressing, dehydration and drying process in the 15th and 16th bins.

[0043] In other embodiments, the present invention further provides a washing system including the above-mentioned tunnel washer with good energy-saving effect, and the energy saving of the entire equipment is improved by the energy-saving effect of the above-mentioned tunnel washer.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
