Technical Field

[0001] The utility model relates to the field of mercerizing machine equipment, in particular to a waste heat recovery type mercerizing machine. Background Art

[0002] Mercerizing machine is a device that treats cotton yarn and cotton fabric with concentrated caustic soda solution under certain tension conditions and washes and removes alkali. In knitting production, it is mainly used for processing weft-knitted tubular cotton knitted fabrics. The mercerizing machine is mainly composed of a cloth feeding rack, an alkali dipping tank, a ventilation device, a width expansion device, a flushing device and a de-alkali steamer.

[0003] In the prior art, mercerized woven fabrics are dealkali-free in a dealkali steamer. After being removed from the steam chamber, a large amount of steam waste heat remains in the steam chamber and cannot be effectively utilized, resulting in a waste of energy.

[0004] Therefore, a waste heat recovery type mercerizing machine is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a waste heat recovery mercerizing machine to solve the problem that after the fabric is dealkali-removed in the dealkali steamer and removed from the steam chamber, a large amount of steam waste heat remains in the steam chamber and cannot be effectively utilized, resulting in energy waste.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a waste heat recovery type mercerizing machine, comprising a frame, a de-alkali steamer with a steam chamber and a heat-conducting component, characterized in that: the de-alkali steamer is provided with an opening communicating with the outside and is fixedly connected to the frame, the heat-conducting component is fixedly connected to the top surface of the de-alkali steamer, and the heat-conducting component is recessed inward to form a hot washing tank, the bottom end of the heat-conducting component is located in the steam chamber, and the steam in the de-alkali steamer flows upward to transfer heat to the bottom end of the heat-conducting component.

[0007] By adopting the above technical solution, the steam in the steam chamber can transfer heat to the heat-conducting component. The heat-conducting component is recessed inward to form a hot washing tank. When water flows through the hot washing tank, the heat absorbed by the heat-conducting component will be transferred to the water in the hot washing tank. The hot washing tank does not need additional excessive heat for heating. The steam removes the alkali solution on the fabric and heats the water in the hot washing tank with the heat of the steam, thereby realizing effective utilization of waste heat.

[0008] The utility model is further configured as follows: the heat-conducting component comprises a fixing ring and a heat-conducting part, the fixing ring is fixedly connected to the top surface of the de-alkali steam box and is integrally formed with the heat-conducting part, the heat-conducting part is a U-shaped ring cylinder and the heating surface is an arc surface, and the inner concave part of the heat-conducting part is a cylindrical hot washing tank.

[0009] By adopting the above technical solution, when the heat of the steam is transferred to the heat-conducting member, the annular curved surface makes the heating more uniform, and the heat distribution on the heat-conducting member is more uniform, so that the washing effect is better when washing fabrics with hot water in the hot washing tank.

[0010] The utility model is further configured as follows: a plurality of U-shaped convex strips distributed in a circumferential array are fixedly connected to the bottom surface of the heat conducting member, the arc surface of the convex strips is tightly fitted with the bottom surface of the heat conducting member, and the U-shaped convex strips are fixedly connected to the inner wall of the steam chamber.

[0011] By adopting the above technical solution, the convex strips enable the heat-conducting element to be more stably fixed in the steam chamber, while increasing the heating area of ​​the bottom surface of the heat-conducting element, so that the efficiency of transferring steam heat to the heat-conducting element is faster.

[0012] The utility model is further configured as follows: a collecting component is fixedly connected to the inner wall of the steam chamber, and the collecting component is located 2 cm to 3 cm below the heat conductive part, the collecting component includes a plurality of support frames and a cylindrical water collecting part with a water collecting trough, and the support frame is fixedly connected between the inner wall of the steam chamber and the outer wall of the water collecting part.

[0013] By adopting the above technical solution, when the steam on the bottom surface of the heat-conducting member transfers heat, part of the steam condenses into water droplets, and the water collection tank can effectively collect the water droplets to prevent the water droplets from falling onto the fabric in the steam chamber and causing pollution.

[0014] The utility model is further configured as follows: a sealing ring is fixedly connected between the top surface of the de-alkali steam box and the bottom surface of the heat conduction component.

[0015] By adopting the above technical solution, the sealing ring prevents steam from being lost and dissipated from the heat-conducting member and the steam chamber to affect the heat transfer effect.

[0016] The utility model is further configured as follows: the sealing ring has thermal conductivity, the specific heat capacity of the sealing ring is greater than the specific heat capacity of the inner and outer walls of the de-alkali steam box, and the specific heat capacity of the sealing ring is less than the specific heat capacity of the heat conducting member.

[0017] By adopting the above technical solution, the sealing ring can absorb the heat on the inner and outer walls of the de-alkali steam box, and the fixing ring then transfers the heat absorbed by the sealing ring to the heat conducting member to further utilize the heat.

[0018] The utility model is further configured as follows: a negative pressure pipeline penetrating the box body to the steam chamber is opened on the outer wall of the de-alkali steam box, and the negative pressure pipeline is connected to an external negative pressure system.

[0019] By adopting the above technical solution, the external negative pressure system connected to the negative pressure pipeline can only flow steam upwards without backflow, and the steam produced by the steam chamber is effectively transferred to the heat-conducting member.

[0020] In summary, the utility model has the following beneficial effects: when the fabric on the frame is transported to the de-alkali steam box to remove the fabric alkali liquid, a negative pressure is formed in the steam chamber, so that the steam flows upward and transfers the heat to the heat conductive part. The heating surface of the heat conductive part is an arc surface, so that the heat conductive part is heated more evenly, and the heat is distributed more evenly in the heat conductive part. The sealing ring prevents the steam in the steam chamber from being lost, and at the same time, the heat absorbed by the inner and outer walls of the box body can be absorbed and transferred to the heat conductive component. At the same time, the heat conductive part is recessed inward to form a hot washing tank. After water is passed, the heat absorbed by the bottom surface of the heat conductive part is evenly distributed in the heat conductive part, and then transferred to the water in the hot washing tank. No additional heat energy is required to heat the water in the hot washing tank, so that steam de-alkali is achieved and the hot washing tank is heated at the same time, and the waste heat in the steam chamber is effectively utilized, saving energy.

[0028] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Example:

[0030] like Figure 1 to Figure 2As shown, the waste heat recovery type mercerizing machine includes a frame 11, a de-alkali steam box 12 and a heat conduction component. The de-alkali steam box 12 is fixedly connected to the frame 11, so that the fabric after alkali soaking is transported to the de-alkali steam box 12 through the frame 11 to remove the alkali solution. The top of the de-alkali steam box 12 is provided with an opening connected to the outside world. The fixing ring 14 of the heat conduction component is welded to the top surface of the de-alkali steam box 12, and the heat conduction member 15 is fixed on the de-alkali steam box 12. The heat conduction member 15 of the heat conduction component is located in the alkali steam box. The steam in the de-alkali steam box 12 flows upward to transfer heat to the heat-conducting member 15, and the heat-conducting member 15 is recessed inward to form a hot washing tank 16. The heat-conducting member 15 absorbs the heat and then transfers it to the water in the hot washing tank 16. While the steam in the de-alkali steam box 12 removes the alkali liquid of the fabric, it flows upward to transfer heat to the hot washing tank 16 formed by the heat-conducting member 15, so that the hot washing tank 16 does not need additional excessive heat energy to heat water, and the waste heat of the steam in the steam box is effectively utilized, which effectively saves energy.

[0031] like Figures 2 to 3 As shown, the fixing ring 14 of the heat-conducting component is a circular fixing ring 14 made of aluminum material, the inner diameter of the outer ring of the fixing ring 14 is larger than the inner diameter of the opening of the de-alkali steam box 12, and the thickness of the fixing ring 14 is 3 cm. The fixing ring 14 is fixed to the top surface of the opening of the de-alkali steam box 12 by welding, and a U-shaped ring-shaped heat-conducting member 15 is integrally formed at the inner ring of the fixing ring 14. The thickness of the heat-conducting member 15 is 5 cm, and the bottom surface of the heat-conducting member 15 is a spherical arc surface. The inward concave part of the heat-conducting member 15 is a cylindrical hot washing tank 16, the opening cross-section of the hot washing tank 16 is circular, the bottom surface is a spherical arc surface, and the depth of the hot washing tank 16 is 6 decimeters.

[0032] The fixing ring 14 and the heat-conducting member 15 of the heat-conducting assembly are made of aluminum material to have good thermal conductivity, which can better absorb the heat transferred by steam. At the same time, the fixing ring 14 and the heat-conducting member 15 have a certain strength, and are not easily corroded and damaged after long-term use, thereby ensuring the heat transfer efficiency and service life of the heat-conducting assembly. The outer ring diameter of the fixing ring 14 is larger than the diameter of the opening of the de-alkali steam box 12, so that the fixing ring 14 is more firmly supported and fixed on the top surface of the de-alkali steam box 12, so that the heat-conducting assembly is fixed in the de-alkali steam box 12 more stably and reliably when working. The heat-conducting member 15 is a U-shaped ring cylinder, and the bottom surface of the heat-conducting member 15 is a spherical arc surface, so that the heating is more uniform, and the heat is more evenly distributed in the heat-conducting member 15. The heat-washing tank 16 is formed at the inward concave part of the heat-conducting member 15. The heat absorbed by the bottom surface of the heat-conducting member 15 is distributed to various parts of the heat-conducting member 15, and then transferred to the water in the hot washing tank 16 to heat-wash the fabric.

[0033] like Figure 3As shown, the spherical arc surface of the heat conductive member 15 is integrally formed with 16 U-shaped convex strips 17 distributed in a circumferential array, and the arc surface of the convex strip 17 is tightly fitted with the bottom surface of the heat conductive member 15. The convex strip 17 extends along the arc surface of the heat conductive member 15 and is welded to the inner wall of the steam chamber 13, and the two ends of the convex strip 17 are welded to the inner wall of the steam chamber 13 so that the heat conductive member 15 is more stably fixed in the de-alkali steam box 12. At the same time, the convex strip 17 increases the heating area of ​​the heat conductive member 15, so that after the steam flows upward, the heat conductive member 15 can more efficiently absorb the heat of the steam and transfer it to the water in the hot washing tank 16.

[0034] like Figure 4 As shown, the support frame 18 of the collecting assembly is a long columnar structure made of stainless steel material. One end of the support frame 18 is welded to the inner wall of the steam chamber 13 in a circular array, and a cylindrical water collecting part 19 is welded to the end away from the inner wall of the steam chamber 13. The water collecting part 19 is made of stainless steel material, and a water collecting trough 20 is opened in the water collecting part 19. The water collecting part 19 is located 2 cm to 3 cm directly below the heat conductive part 15.

[0035] The support frame 18 and the water collecting member 19 are made of stainless steel material so that they have good corrosion resistance and strength. The support frame 18 supports and fixes the water collecting member 19 2 cm to 3 cm directly below the heat conductor 15, which will not affect the heating of the heat conductor 15 and can collect the water droplets condensed by the steam on the bottom surface of the heat conductor 15 without dripping into the fabric in the steam chamber 13 to cause pollution.

[0036] like Figure 2 and Figure 5 As shown, the sealing ring 21 is a circular sealing ring 21 made of 304 stainless steel, the top of the sealing ring 21 is welded to the bottom surface of the fixed ring 14, and the bottom surface of the sealing ring 21 is welded to the top surface of the de-alkali steam box 12. The sealing ring 21 can prevent the upward-flowing steam from dissipating from the gap between the fixed ring 14 and the steam chamber 13, so that the steam in the steam chamber 13 can be efficiently utilized. At the same time, the box body of the de-alkali steam box 12 is made of 410 stainless steel material, and its specific heat capacity is lower than the specific heat capacity of the sealing ring 21. At the same time, the specific heat capacity of the sealing ring 21 is lower than the specific heat capacity of the fixed ring 14. The heat of the inner and outer walls of the box body is absorbed by the sealing ring 21, and the sealing ring 21 then transfers the heat to the fixed ring 14 of the heat-conducting component, so as to further effectively utilize the heat energy.

[0037] like Figure 2As shown, when the frame 11 transports the fabric to the de-alkali steam box 12, the de-alkali steam box 12 emits hot steam to remove the alkali solution on the fabric, and the hot steam after the alkali solution is removed flows upward. At this time, the negative pressure fan externally connected to the negative pressure pipe 22 draws air into the steam chamber 13 to form a negative pressure, so that the hot steam only flows upward and does not flow back downward, and the suction speed of the negative pressure fan is relatively slow, which prevents the hot steam from being drawn away prematurely without transferring the heat to the heat conductive member 15. At the same time, the drawn hot steam can be collected by the negative pressure system connected to the negative pressure pipe 22 to avoid polluting the outside air. The convex strips 17 on the bottom surface of the heat conductive member 15 increase The heat conduction efficiency is improved. The bottom surface of the heat-conducting member 15 is a spherical arc surface, which makes the heating more uniform. The absorbed heat can be evenly distributed in the heat-conducting member 15. Water flows through the hot washing tank 16 formed by the downward depression of the heat-conducting member 15. The heat in the heat-conducting member 15 is then transferred to the water in the hot washing tank 16. The fabric removed from the de-alkali steaming box 12 is then put into the hot washing tank 16 for washing. The steam in the de-alkali steaming box 12 removes the residual alkali solution of the fabric and absorbs the heat and transfers it to the hot washing tank 16. The hot washing tank 16 does not need additional excessive heat energy for heating and washing, and effectively utilizes the waste heat of the steam in the de-alkali steaming box 12, saving energy.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
