Description

Technical Field

[0001] The invention relates to the technical field of environmentally friendly printing and dyeing, and in particular to environmentally friendly printing and dyeing equipment for recycling waste heat. Background Art

[0002] Printing and dyeing, also known as dyeing and finishing, is a processing method, which is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. When dyeing fabrics, in order to ensure the quality of the dyed fabrics, the dyeing time and temperature must be controlled. The temperature of the dye is also a key parameter. Excessive temperature will cause discoloration of the fabric and damage to the fibers.

[0003] The prior art discloses a Chinese patent application number, publication number: CN202744806U, a wastewater heat recovery and reuse device used in the printing and dyeing industry. It discloses that the hot wastewater in the printing and dyeing water tank is recovered through a heat exchanger to recover the heat and reuse it in purified water. By heating the purified water, it can be reused in the printing and dyeing water tank, and through the adjustment of the proportional valve, the heat of the hot wastewater is effectively recovered, thereby saving energy.

[0004] The above device can only recycle and reuse the wastewater used for printing and dyeing. However, when printing and dyeing cloth, in order to avoid discoloration of the fabric due to excessive temperature, the dye temperature must be quickly cooled down when it is too high. The above device cannot recycle the high-temperature steam generated during printing and dyeing and the hot water used for cooling and heat exchange, thus causing a waste of resources. In addition, in order to ensure uniform dyeing of the fabric, the fabric must be stirred and turned over to ensure that the dye penetrates every part of the fabric to avoid uneven dyeing.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention drives the cloth on multiple sets of placement racks to rotate and perform printing and dyeing when the central column rotates. The arrangement of multiple placement racks can meet the printing and dyeing needs of multiple pieces of cloth while also ensuring that the multiple pieces of cloth always remain vertical during printing and dyeing. Moreover, the rotation of the central column drives the multiple pieces of cloth to rotate, which can stir the dye while the cloth is being printed and dyed, without the need for manual stirring of the dye. Compared with the existing printing and dyeing device, the present invention can support multiple pieces of cloth in turn through multiple supporting rods when printing and dyeing, thereby meeting the needs of batch printing and dyeing of cloth, while avoiding entanglement of multiple pieces of cloth during printing and dyeing, and further enhancing the printing and dyeing efficiency of cloth.

[0019] 2. The present invention opens the exhaust pipe to allow the high-temperature steam in the printing and dyeing box to flow into the annular ring through the air transfer pipe, and finally transmits it to the recovery barrel through the exhaust pipe. Then, the piston rod is controlled to rise and fall, and the piston rod rises and falls to compress the external air into the annular ring. The air in the annular ring enters the printing and dyeing box through the air transfer pipe, thereby completing the injection of cold air into the printing and dyeing box, so as to quickly cool down the inside of the printing and dyeing box. At the same time, the water pump is opened to pump the hot water in the holding tank into the recovery barrel, and the water inlet pipe is opened to inject the cold water in the water tank into the holding tank, thereby quickly cooling the dye in the printing and dyeing box.

[0020] 3. The present invention can recycle the high temperature and hot water in the printing and dyeing box for subsequent reuse through the provision of a recovery barrel. Compared with the existing device, the present invention can quickly cool the dye in the printing and dyeing box when printing and dyeing the cloth in the printing and dyeing box, so that the temperature of the dye is controlled, avoiding the situation where the fiber structure of the cloth is damaged or the fabric is discolored due to excessive dye temperature, and the provision of the recovery barrel can recycle the high temperature steam and hot water in the printing and dyeing box for reuse. At the same time, the recovered high temperature steam can also be used to steam-dry the printed and dyed cloth after the dye in the printing and dyeing box is discharged.

[0021] 4. The present invention lifts the pressing plate upward to release the pressure on the supporting rod, and then moves the supporting rod out of the slide slot. When the supporting rod moves upward, the printed and dyed cloth on the supporting rod is simultaneously driven to move upward. When the printed and dyed cloth moves upward, it continuously contacts the squeezing rollers in the pressing plates on both sides. The squeezing rollers roll the printed and dyed cloth when the cloth moves upward, and then squeeze out the print and dye in the cloth to accelerate the drying of the cloth. By placing the supporting rod and the cloth in the through slot again, covering the cover plate, and opening the exhaust pipe to transport the steam recovered in the recovery barrel to the printing and dyeing box without dye, the printed and dyed cloth is steam-dried. At the same time, the electric slider is opened to drive the central column to rotate. When the central column rotates, it simultaneously drives multiple printed and dyed cloths to be dried to rotate in the printing and dyeing box, so that they are fully in contact with the high-temperature steam, further accelerating the drying of the cloth.

[0022] 5. The present invention enables the first bevel gear and the second bevel gear to be meshed with each other by turning on the electric push rod and pushing it forward. When the center column rotates, the dye in the printing and dyeing box is continuously stirred, and the fixed rod is synchronously driven to rotate. When the fixed rod rotates, the electric push rod is synchronously driven to rotate through the pulley and the belt. When the electric push rod rotates, the second bevel gear is driven to rotate through the rotating rod. When the second bevel gear rotates, the cam is driven to rotate. When the cam rotates, the piston rod is driven to rise and fall through the lifting frame. When the piston rod is lifted, the cold air in the piston cylinder is compressed into the printing and dyeing box, thereby cooling the dye in the printing and dyeing box. At the same time, when the piston rod is lifted, the connecting rod is synchronously driven to rise and fall, and the connecting rod is pressed back and forth in the water tank when it is lifted. When the connecting rod is pressed back and forth, the cold water in the water tank is poured into the receiving tank, thereby realizing rapid cooling of the dye in the printing and dyeing box. Compared with the existing printing and dyeing device, the present invention can quickly exchange heat with the dye when the temperature of the dye is too high, so as to cool the dye and avoid discoloration of the fabric and damage to the fiber caused by excessive temperature of the dye.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] like Figures 1-10 As shown, an environmentally friendly printing and dyeing equipment for waste heat recovery and utilization includes a base 1, a printing and dyeing box 2 for holding dyes is fixedly installed in the middle of the upper end surface of the base 1, a receiving groove 20 for filling water to cool the inner wall of the printing and dyeing box 2 is opened in the middle of the outer wall of the printing and dyeing box 2, a circular ring-shaped supporting plate 22 is fixedly installed on the upper part of the inner wall of the printing and dyeing box 2, a cover plate 23 for covering and sealing the printing and dyeing box 2 is placed on the supporting plate 22, an annular ring 21 is fixedly installed on the upper part of the printing and dyeing box 2, and a plurality of annularly arranged air transfer pipes 24 are fixedly installed on the upper end surface of the annular ring 21, and the air transfer pipes 24 are away from the annular ring. One end of the annular ring 21 passes through the support plate 22 and is placed inside the printing and dyeing box 2. A recovery bucket 3 fixedly connected to the base 1 is provided on one side of the printing and dyeing box 2. An exhaust pipe 32 is commonly connected between the annular ring 21 and the recovery bucket 3, and a water suction pipe 31 is commonly connected between the lower end surface of the accommodating groove 20 and the recovery bucket 3. A drain pipe is provided on one side of the lower end surface of the printing and dyeing box 2. A central column 26 is installed in the middle of the printing and dyeing box 2 through an electric slider. A plurality of groups of circumferentially arranged placement racks 261 are installed on the outer wall of the central column 26, and a supporting rod 263 for hanging fabrics is placed between each group of placement racks 261.

[0038] The fabrics to be printed and dyed are placed on the supporting rods 263 in sequence, and then multiple supporting rods 263 are placed on each group of placement racks 261 in sequence. The dye is injected into the printing and dyeing box 2, and the printing and dyeing box 2 is opened to heat the dye. Then, the cover plate 23 is closed, and the electric slider is opened to drive the central column 26 to rotate. When the central column 26 rotates, the fabrics on the multiple groups of placement racks 261 are driven to rotate and dye. The arrangement of multiple groups of placement racks 261 can meet the requirements of printing and dyeing multiple pieces of fabric while ensuring that the multiple pieces of fabric can always remain straight during printing and dyeing. Moreover, when the central column 26 rotates, the multiple pieces of fabric are driven to rotate, so that the fabrics can stir the dye while printing and dyeing, without the need for manual stirring of the dye.

[0039] Compared with the existing printing and dyeing device, the present invention can support multiple pieces of cloth in sequence through multiple supporting rods 263 when printing and dyeing cloth, which can meet the needs of batch printing and dyeing of cloth, and avoid entanglement of multiple pieces of cloth during printing and dyeing, thereby further improving the printing and dyeing efficiency of cloth.

[0040] In order to ensure the printing and dyeing effect of the fabric, the temperature of the dye needs to be controlled. When the temperature in the printing and dyeing box 2 is too high, the dye in the printing and dyeing box 2 needs to be cooled down quickly. At this time, the exhaust pipe 32 is opened, and the high-temperature steam in the printing and dyeing box 2 flows into the annular ring 21 through the air transmission pipe 24, and is finally transmitted to the recovery barrel 3 through the exhaust pipe 32. Then, the piston rod 41 is controlled to rise and fall. The piston rod 41 rises and falls to compress the outside air into the annular ring 21. The air in the annular ring 21 enters the printing and dyeing box 2 through the air transmission pipe 24, thereby completing the injection of cold air into the printing and dyeing box 2, so as to quickly cool down the inside of the printing and dyeing box 2. At the same time, the water pumping pipe 31 is opened to pump the hot water in the receiving tank 20 into the recovery barrel 3, and the water inlet pipe 52 is opened to inject the cold water in the water tank 5 into the receiving tank 20, thereby quickly cooling down the dye in the printing and dyeing box 2.

[0041] By setting up the recovery barrel 3, the high temperature and hot water in the printing and dyeing box 2 can be recovered for subsequent reuse. Compared with the existing device, the present invention can quickly cool down the dye in the printing and dyeing box 2 when the printing and dyeing box 2 is printing and dyeing the cloth, so that the temperature of the dye is controlled, and the situation that the fiber structure of the cloth is damaged or the fabric is discolored due to excessive dye temperature is avoided. In addition, by setting up the recovery barrel 3, the high temperature steam and hot water in the printing and dyeing box 2 can be recovered for reuse. At the same time, the recovered high temperature steam can also be used to steam-dry the printed and dyed cloth after the dye in the printing and dyeing box 2 is discharged.

[0042] A plurality of circularly arranged arc plates 25 are fixedly installed on the inner wall of the printing and dyeing box 2, and a guide plate 262 is symmetrically installed on one side of each group of placement racks 261. A through groove is provided between the guide plate 262 and the placement rack 261, and the supporting rod 263 is placed in the through groove. A lifting groove 264 is symmetrically provided between each group of placement racks 261, and a horizontal plate 265 is slidably installed between the two corresponding lifting grooves 264. A spring is commonly connected between the upper end surface of the horizontal plate 265 and the lifting groove 264, and a semi-arc-shaped pressing plate 266 is fixedly installed on the lower end surface of the horizontal plate 265. A return frame 27 is installed at the bottom and middle of the two placement racks 261 of each group, and an extrusion assembly is provided on the return frame 27.

[0043] The cloth to be printed and dyed is hung on the supporting rod 263, and then the supporting rod 263 is placed through the through slots on the two guide plates 262, and then the lower part of the cloth is passed through the middle of the upper return frame 27, and the supporting rod 263 rolls along the through slots to the two placement racks 261, and the pressing plate 266 can press the supporting rod 263 and the cloth under the pressure of the spring. The setting of the pressing plate 266 can, on the one hand, keep the supporting rod 263 stable in the through slot, and on the other hand, prevent the cloth from slipping on the supporting rod 263 when the center column 26 rotates and drives the cloth to rotate.

[0044] The extrusion assembly includes an ear plate 271, which is fixed on the middle part of the outer placement rack 261, and the ear plate 271 is symmetrically arranged on the placement rack 261. The two ear plates 271 are slidably installed with a U-shaped rod 272. Springs are provided on both sides of the U-shaped rod 272, and U-shaped plates 274 are fixedly installed at both ends of the U-shaped rod 272.

[0045] The two ends of the U-shaped plate 274 away from the U-shaped rod 272 are fixedly installed with a first wedge block 275. One side of the first wedge block 275 is provided with a sliding rod 276 that passes through and slides on the return frame 27. The second wedge block 277 is fixedly installed on the end of the sliding rod 276 close to the first wedge block 275. A spring is provided on the outside of the sliding rod 276. A pressing plate 278 is fixedly installed between the upper and lower sliding rods 276. An arc plate 273 is fixedly installed in the middle of the U-shaped rod 272.

[0046] When the electric slider is turned on to drive the central column 26 to rotate, the arc plate 273 intermittently contacts the arc plate 25 on the inner wall of the printing and dyeing box 2. When the arc plate 273 contacts the arc plate 25, it is squeezed by the arc plate 25. At this time, the arc plate 273 drives the U-shaped rod 272 to move towards the central column 26. When the U-shaped rod 272 moves, it synchronously drives the C-shaped plates 274 on both sides to move. When the C-shaped plates 274 move, they squeeze the second wedge block 277 through the first wedge block 275. After being squeezed, the second wedge block 277 synchronously makes the pressing plates 278 on both sides move closer through the sliding rods 276 on both sides. When the pressing plates 278 on both sides move closer, they press the fabric during printing and dyeing. By repeatedly squeezing both sides of the fabric with the pressing plates 278, the fabric can fully adsorb the dye and accelerate the dyeing efficiency of the fabric.

[0047] A groove 2781 is formed on the side of the pressing plate 278 close to the fabric, and a plurality of squeezing rollers 2782 are rotatably installed in the middle of the groove 2781 from top to bottom.

[0048] After the fabric is dyed, after discharging the dye in the printing and dyeing box 2, at this time, the central column 26 rotates to the position where the arc plate 273 and the arc plate 25 are in contact. Then, the pressing plate 266 is lifted upward to cancel the pressing on the supporting rod 263. Then, the supporting rod 263 is removed from the sliding groove. When the supporting rod 263 is moved upward, it synchronously drives the dyed fabric on the supporting rod 263 to move upward. When the dyed fabric moves upward, it continuously contacts the squeezing rollers 2782 in the pressing plates 278 on both sides. The squeezing rollers 2782 roll-press the dyed fabric when the fabric moves upward, thereby squeezing out the printing and dyeing in the fabric to accelerate the drying of the fabric. By placing the supporting rod 263 and the fabric in the through groove again, covering the cover plate 23, and turning on the air extraction pipe 32 to输送 the steam recovered in the recovery barrel 3 to the printing and dyeing box 2 without dye, the dyed fabric is steam-dried. At the same time, the electric slider is turned on to drive the central column 26 to rotate. When the central column 26 rotates, it synchronously drives a plurality of dyed fabrics to be dried to rotate in the printing and dyeing box 2, making them fully contact with the high-temperature steam, further accelerating the drying of the fabric.

[0049] A ring support 33 is fixedly installed outside the recovery barrel 3, and the ring support 33 supports one side of the water extraction pipe 31. A piston cylinder 4 is fixedly installed on one side of the printing and dyeing box 2. The upper end of the piston cylinder 4 is connected to the annular ring 21, and a piston rod 41 that penetrates and slides in the middle of the piston cylinder 4 is provided at the lower end of the piston cylinder 4. A fixing plate 42 fixedly connected to the bottom of the printing and dyeing box 2 is provided on one side of the piston rod 41, and a rotating rod 43 is rotatably installed in the middle of the fixing plate 42.

[0050] A cam 44 is fixedly mounted on one end of the rotating rod 43 close to the piston cylinder 4, a circular shaft 45 is fixedly mounted on one side of the cam 44, a lifting frame 46 is sleeved on the outer side of the circular shaft 45, and the top of the lifting frame 46 is fixedly connected to the piston rod 41, and a second bevel gear 431 is fixedly mounted on the other end of the rotating rod 43.

[0051] When the temperature of the dye in the printing and dyeing box 2 is cooled, the electric push rod 48 is turned on and pushed forward to engage the first bevel gear 480 with the second bevel gear 431. When the center column 26 rotates, the dye in the printing and dyeing box 2 is continuously stirred, and the fixed rod 47 is synchronously driven to rotate. When the fixed rod 47 rotates, the electric push rod 48 is synchronously driven to rotate through the pulley 49 and the belt 490. When the electric push rod 48 rotates, the second bevel gear 431 is driven to rotate through the first bevel gear 480. When the second bevel gear 431 rotates, the cam 44 is driven to rotate through the rotating rod 43. When the cam 44 rotates, the piston rod 4 is driven through the lifting frame 46. 1 is lifted and lowered. When the piston rod 41 is lifted and lowered, the cold air in the piston cylinder 4 is compressed into the printing and dyeing box 2, thereby cooling the dye in the printing and dyeing box 2. At the same time, when the piston rod 41 is lifted and lowered, the connecting rod 51 is synchronously driven to lift and lower. When the connecting rod 51 is lifted and lowered, the water tank 5 is reciprocated. When the connecting rod 51 is reciprocated, the cold water in the water tank 5 is poured into the containing tank 20, thereby realizing rapid cooling of the dye in the printing and dyeing box 2. Compared with the existing printing and dyeing device, the present invention can quickly exchange heat for the dye when the dye temperature is too high, so as to cool the dye and avoid discoloration of the fabric and damage to the fiber caused by excessive dye temperature.

[0052] An electric push rod 48 rotatably connected to the base 1 is provided below the second bevel gear 431 . A first bevel gear 480 is fixedly mounted on the telescopic end of the electric push rod 48 . The first bevel gear 480 meshes with the second bevel gear 431 when the electric push rod 48 is pushed upward.

[0053] The meshing between the first bevel gear 480 and the second bevel gear 431 is cancelled by retracting the electric push rod 48, so that the temperature of the dye in the printing and dyeing box 2 stops decreasing.

[0054] A fixing rod 47 is fixedly mounted on the lower end surface of the center column 26 , and pulleys 49 are fixedly mounted on both the fixing rod 47 and the electric push rod 48 , and a belt 490 is commonly connected between the two pulleys 49 .

[0055] A water tank 5 is fixedly mounted on one side of the upper end surface of the base 1 , a connecting rod 51 is fixedly mounted on one end of the piston rod 41 , and a piston is connected to the end of the connecting rod 51 away from the piston rod 41 . A water inlet pipe 52 is commonly connected between the water tank 5 and the containing tank 20 .

[0056] When the present invention is in use, the cloth to be printed and dyed is hung on the supporting rod 263, and then the supporting rod 263 is placed through the through slots on the two guide plates 262, and then the lower part of the cloth is passed through the middle of the upper return frame 27, and the supporting rod 263 rolls down along the through slot to the two placement racks 261, and the supporting rod 263 and the cloth can be pressed by the pressing plate 266 under the pressure of the spring. The setting of the pressing plate 266 can keep the supporting rod 263 stable in the through slot on the one hand, and on the other hand, it can prevent the cloth from rotating when the center column 26 rotates and drives the cloth to rotate. To prevent the fabric from slipping on the supporting rod 263, the printing and dyeing box 2 is opened to heat the dye, and then the cover plate 23 is closed. The electric slider is opened to drive the central column 26 to rotate. When the central column 26 rotates, the fabrics on the multiple sets of placement racks 261 are driven to rotate and dye. The arrangement of the multiple sets of placement racks 261 can meet the needs of printing and dyeing multiple pieces of fabric while ensuring that the fabrics always remain straight during printing and dyeing. Moreover, when the central column 26 rotates, the fabrics are driven to rotate, so that the fabrics can stir the dyes while printing and dyeing, without the need for manual stirring of the dyes.

[0057] The exhaust pipe 32 is opened, and the high-temperature steam in the printing and dyeing box 2 flows into the annular ring 21 through the air transfer pipe 24, and is finally transmitted to the recovery barrel 3 through the exhaust pipe 32. Then, the piston rod 41 is controlled to rise and fall. The piston rod 41 rises and falls to compress the outside air into the annular ring 21. The air in the annular ring 21 enters the printing and dyeing box 2 through the air transfer pipe 24, thereby completing the injection of cold air into the printing and dyeing box 2, so as to quickly cool down the inside of the printing and dyeing box 2. At the same time, the water pumping pipe 31 is opened, and the water pumping pipe 31 pumps the hot water in the holding tank 20 into the recovery barrel 3. The water inlet pipe 52 is opened to inject the cold water in the water tank 5 into the holding tank 20, thereby quickly cooling the dye in the printing and dyeing box 2. When the electric slider is opened to drive the central column 26 to rotate, the arc plate 27 The arc plate 273 intermittently contacts the arc plate 25 on the inner wall of the printing and dyeing box 2. When the arc plate 273 contacts the arc plate 25, it is squeezed by the arc plate 25. At this time, the arc plate 273 drives the U-shaped rod 272 to move toward the central column 26. When the U-shaped rod 272 moves, it simultaneously drives the U-shaped plates 274 on both sides to move. When the U-shaped plates 274 move, they squeeze the second wedge block 277 through the first wedge block 275. After the second wedge block 277 is squeezed, the sliding rods 276 on both sides synchronously move the pressing plates 278 on both sides closer together. When the pressing plates 278 on both sides approach each other, they press the fabric being printed and dyed. The repeated squeezing of the two sides of the fabric by the pressing plates 278 can make the fabric fully absorb the dye, thereby accelerating the dyeing efficiency of the fabric.

[0058] After the fabric is dyed, the dye in the printing and dyeing box 2 is discharged. At this time, the center column 26 rotates until the arc plate 273 contacts the arc plate 25, and then the pressing plate 266 is lifted upward to cancel the pressing on the supporting rod 263. Then, the supporting rod 263 is moved out of the chute. When the supporting rod 263 moves upward, the printed and dyed fabric on the supporting rod 263 is simultaneously driven to move upward. When the printed and dyed fabric moves upward, it continuously contacts the squeezing rollers 2782 in the pressing plates 278 on both sides. The squeezing rollers 2782 roll the printed and dyed fabric when the fabric moves upward. The steam in the cloth is squeezed out to accelerate the drying of the cloth. The supporting rod 263 and the cloth are placed in the through groove again, the cover plate 23 is closed, and the exhaust pipe 32 is opened to transport the steam recovered in the recovery barrel 3 to the printing and dyeing box 2 without dye, thereby steam drying the printed and dyed cloth. At the same time, the electric slider is opened to drive the central column 26 to rotate. When the central column 26 rotates, it simultaneously drives multiple printed and dyed cloths to be dried to rotate in the printing and dyeing box 2, so that they are fully exposed to the high-temperature steam, further accelerating the drying of the cloth.

[0059] When the temperature of the dye in the printing and dyeing box 2 is cooled, the electric push rod 48 is turned on and pushed forward to engage the first bevel gear 480 with the second bevel gear 431. When the center column 26 rotates, the dye in the printing and dyeing box 2 is continuously stirred, and the fixed rod 47 is synchronously driven to rotate. When the fixed rod 47 rotates, the electric push rod 48 is synchronously driven to rotate through the pulley 49 and the belt 490. When the electric push rod 48 rotates, the second bevel gear 431 is driven to rotate through the first bevel gear 480. When the second bevel gear 431 rotates, the cam 44 is driven to rotate through the rotating rod 43. When the cam 44 rotates, the piston rod 4 is driven through the lifting frame 46. 1 is lifted and lowered. When the piston rod 41 is lifted and lowered, the cold air in the piston cylinder 4 is compressed into the printing and dyeing box 2, thereby cooling the dye in the printing and dyeing box 2. At the same time, when the piston rod 41 is lifted and lowered, the connecting rod 51 is synchronously driven to lift and lower. When the connecting rod 51 is lifted and lowered, the water tank 5 is reciprocated. When the connecting rod 51 is reciprocated, the cold water in the water tank 5 is poured into the containing tank 20, thereby realizing rapid cooling of the dye in the printing and dyeing box 2. Compared with the existing printing and dyeing device, the present invention can quickly exchange heat for the dye when the dye temperature is too high, so as to cool the dye and avoid discoloration of the fabric and damage to the fiber caused by excessive dye temperature.
