Description

Technical Field

[0001] The invention relates to the technical field of heat energy recovery, in particular to a printing and dyeing setting machine with a heat energy recovery function. Background Art

[0002] The dyeing and printing setting machine is mainly used to set the fabric. It includes a cloth feeding device, a tentering device, a heating device, a cooling device and a cloth dropping device. During the working process, the dyeing and printing setting machine will generate high-temperature exhaust gas. Based on the concept of green environmental protection, the existing dyeing and printing setting machine usually uses a filtering device to purify the exhaust gas and recovers the heat energy through a heat recovery device, which avoids environmental pollution and improves the heat utilization rate. However, when the exhaust gas is used to heat water to recover heat energy, scale will form inside the pipe, affecting the heat exchange efficiency of the pipe.

[0003] To this end, a Chinese patent with authorization announcement number CN221147278U discloses a heat recovery device for converting cold water into hot water for a textile printing and dyeing setting machine, which can remove scale on the inner wall of the copper tube by adding a descaling component inside the copper tube, thereby improving the heat recovery efficiency of the copper tube. The descaling component circulates the descaling liquid into the copper tube through a descaling cleaning box, connecting pipe one, connecting pipe two and circulating pump two, so that the scale on the inner wall of the copper tube dissolves and falls off and flows into the descaling cleaning box with the descaling liquid. No manual cleaning is required, which reduces labor and improves cleaning efficiency.

[0004] Since the exhaust gas contains waste such as oil particles and fibers, some of the waste will adhere to the pipe when the airflow contacts the pipe. After long-term operation, a layer of dirt will form on the outer wall of the pipe, which will block the heat exchange and affect the heat exchange between the exhaust gas and water.

Detailed implementation manners

[0031] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0032] Refer to Figures 1 - 5: A printing and setting machine with a heat energy recovery function, comprising a heating mechanism 1, a recovery tank 2 and a control mechanism 3; a connecting pipe 11 is provided on the heating mechanism 1; a filter plate 21 is provided in the recovery tank 2, and the filter plate 21 divides the internal cavity of the recovery tank 2 into a heat exchange cavity and a filtration cavity, and the connecting pipe 11 communicates with the filtration cavity; an exchange tank 22 is provided in the heat exchange cavity of the recovery tank 2, guide rails are provided in the exchange tank 22, a movable plate 221 and a detachable mounting plate 222 are slidably mounted on the guide rails, a copper pipe 2221 and a first support plate 2222 are provided on the mounting plate 222; a nitrogen gas spring 223 is provided in the exchange tank 22, the piston rod of the nitrogen gas spring 223 is connected to the movable plate 221, and a first side plate 224 is provided on each side of the exchange tank 22; a second side plate 23 is provided on each side of the recovery tank 2, the two first side plates 224 are respectively abutted against the two second side plates 23, and a mounting groove matched with the first support plate 2222 is opened on the outer side of the second side plate 23, and a through groove for the mounting plate 222 to pass through is opened in the mounting groove; the control mechanism 3 includes a fixing component 31; in the working state, when the mounting plate 222 is in the installed state, the first support plate 2222 on the mounting plate 222 is inserted and matched with the mounting groove of the second side plate 23, and the fixing component 31 restricts the movement of the mounting plate 222; when the mounting plate 222 is removed, the movable plate 221 is abutted against the first side plate 224 under the elastic force of the nitrogen gas spring 223 and blocks the through groove on the second side plate 23.

[0033] The present invention realizes the function of quickly disassembling and assembling the copper pipe 2221 through the movable plate 221, the mounting plate 222, the nitrogen gas spring 223 and the fixing component 31 in the recovery tank 2, thereby facilitating the operator to clean and maintain the outer wall and the inner wall of the copper pipe 2221, maintaining the heat exchange efficiency of the copper pipe 2221, keeping the high-efficiency recovery of the heat energy in the waste gas, and effectively solving the problem that the adhesion of dirt on the surface of the copper pipe 2221 for heat exchange hinders the heat exchange. An exhaust pipe is provided at the top of the recovery tank 2, a fixing plate is provided in the exchange tank 22, and a pipe for guiding the flow of water is opened in the fixing plate. When the mounting plate 222 is in the installed state, the copper pipe 2221 on the mounting plate 222 is communicated with the pipe on the fixing plate through the movable plate 221, and then the water flow is kept moving in the specified direction for effective heat absorption and energy storage. The nitrogen gas spring 223 is a specially made high-temperature resistant nitrogen gas spring 223, so as to avoid the influence of the high temperature of the waste gas on the elastic performance of the nitrogen gas spring 223.

[0034] In the working state, the waste gas generated by the heating mechanism 1 enters the filtration cavity of the recovery tank 2 through the connecting pipe 11, and after being filtered by the filter plate 21, the waste gas enters the heat exchange cavity and enters the exchange tank 22. After the waste gas contacts the copper pipe 2221 on the mounting plate 222, heat exchange is carried out to heat the water in the copper pipe 2221, and then heat energy recovery is carried out. Finally, the waste gas is discharged from the exhaust pipe at the top of the recovery tank 2.

[0035] When the copper tube 2221 needs to be cleaned and maintained, the operator first releases the movement restriction of the fixing component 31 on the mounting plate 222. The movable plate 221 is pushed under the elastic force of the nitrogen spring 223. The movable plate 221 transmits the thrust to the mounting plate 222, driving the mounting plate 222 to move synchronously along the guide rail, ejecting the mounting plate 222 and the copper tube 2221. Then the operator removes the mounting plate 222. When the mounting plate 222 is completely removed, the movable plate 221 abuts against the inner wall of the exchange box 22 under the elastic force of the nitrogen spring 223, and the outer wall of the exchange box 22 abuts against the second side plate 23. Thus, the through groove on the second side plate 23 is blocked by the movable plate 221 to prevent waste gas from leaking through the through groove of the second side plate 23. When installing the copper tube 2221, the mounting plate 222 is inserted into the through groove, and the first support plate 2222 is pushed to make the mounting plate 222 slide into the guide rail in the recovery box 2 until the first support plate 2222 is inserted and matched with the mounting groove of the second side plate 23. At this time, the nitrogen spring 223 is in a compressed state, and the movable plate 221 is butted against the fixing plate in the recovery box 2. The fixing component 31 fixes the mounting plate 222 to prevent the mounting plate 222 and the movable plate 221 from popping out by themselves under the elastic force of the nitrogen spring 223.

[0036] Refer to Figure 2 and Figure 6 : The fixing component 31 includes a mounting seat 311, a clamping strip 312 and a first elastic member 313; the mounting seat 311 is arranged on the first side plate 224; the clamping strip 312 is slidably mounted on the mounting seat 311; both ends of the first elastic member 313 are respectively connected to the mounting seat 311 and the clamping strip 312; the first support plate 2222 is provided with a first control component 32 for releasing the movement restriction of the fixing component 31 on the mounting plate 222.

[0037] The present invention realizes the function of restricting the movement of the mounting plate 222 through the mounting seat 311, the clamping strip 312 and the first elastic member 313. When the mounting plate 222 is in the installed state, the movement of the mounting plate 222 is restricted by the abutment of the clamping strip 312 against the mounting plate 222 to prevent the mounting plate 222 from popping out under the elastic force of the nitrogen spring 223. When disassembling the copper tube 2221, the operator controls the clamping strip 312 to move away from the mounting plate 222 through the first control component 32. The first elastic member 313 contracts, and the clamping strip 312 contracts into the mounting seat 311, so that the clamping strip 312 is separated from the mounting plate 222, releasing the movement restriction of the fixing component 31 on the mounting plate 222.

[0038] Refer to Figure 5 and Figure 7:A cross plate 2211 is provided on the movable plate 221, and a docking groove 2212 cooperating with the clamping strip 312 is formed on the cross plate 2211. When the clamping strip 312 is inserted and cooperated with the docking groove 2212, the clamping strip 312 restricts the movement of the cross plate 2211; an extension platform 2223 for clamping with the clamping strip 312 is provided on the mounting plate 222; a second control assembly 33 for releasing the movement restriction of the fixed assembly 31 on the movable plate 221 is provided on the mounting plate 222.

[0039] The present invention realizes the function of restricting the movement of the movable plate 221 or the mounting plate 222 through the fixed assembly 31 by means of the cross plate 2211, the docking groove 2212 and the extension platform 2223, so that after the mounting plate 222 is disassembled, when the movable plate 221 abuts against the first side plate 224 under the elastic force of the nitrogen spring 223, the movement of the movable plate 221 can be restricted by the fixed assembly 31, thereby ensuring the plugging stability of the movable plate 221 for the through groove. An inclined surface is provided on the side of the extension platform 2223 away from the first support plate 2222. At least two guide rails are provided in the exchange box 22, and a fixed assembly 31 is provided on the upper side of each guide rail. Two cross plates 2211 are provided on each movable plate 221. When the movable plate 221 abuts against the end of the mounting plate 222, the two cross plates 2211 respectively abut against the upper and lower sides of the movable plate 221. When inserting the mounting plate 222, first make the mounting plate 222 abut against the movable plate 221, and then release the movement restriction of the fixed assembly 31 on the movable plate 221 through the second control assembly 33. During the process of inserting the mounting plate 222, the clamping strip 312 is in an extended state under the elastic force of the first elastic member 313, and then the clamping strip 312 abuts against the surface of the copper pipe 2221. During the movement of the mounting plate 222, the two clamping strips 312 respectively rub against the two surfaces of the copper pipe 2221 to scrape the surface of the copper pipe 2221, playing a certain cleaning role. When the extension platform 2223 contacts the clamping strip 312, the inclined surface of the extension platform 2223 presses the clamping strip 312, so that the clamping strip 312 can be smoothly clamped with the extension platform 2223, playing a role in restricting the movement of the extension platform 2223 and the mounting plate 222.

[0040] Refer to Figure 4 :A detachable collection box 225 is provided on the first side plate 224 of the exchange box 22. A cover plate 2251 is provided on the side of the collection box 225 away from the exchange box 22, and a first handle 2252 for grasping is installed on the cover plate 2251.

[0041] The present invention realizes the function of collecting dirt through the collecting box 225, the cover plate 2251 and the first handle 2252. There is a gap for dirt to pass through between the mounting plate 222 and the copper pipe 2221. During the process of disassembling and assembling the mounting plate 222, due to the frictional effect of the clamping strip 312 on the surface of the copper pipe 2221, a part of the dirt attached to the surface of the copper pipe 2221 can be scraped off. The scraped-off dirt falls into the collecting box 225 under the action of gravity. Through the gap between the mounting plate 222 and the copper pipe 2221, the dirt on the copper pipe 2221 of the upper guide rail will not fall onto the lower copper pipe 2221, avoiding the situation that the copper pipe 2221 located at the lower layer is secondarily polluted and accumulates more dirt. During cleaning, the operator holds the first handle 2252 and pulls out the collecting box 225 from the exchange box 22 for centralized cleaning. Since the collecting box 225 only collects part of the dirt during the process of disassembling and assembling the mounting plate 222, it is not necessary to frequently disassemble and assemble the collecting box 225 for cleaning. Therefore, in order to improve the stability of the collecting box 225 after installation, the cover plate 2251 and the second side plate 23 can be connected by bolts or other connecting parts. The bolts are not shown in the figure.

[0042] Refer to Figures 5 - 7 : A reset mechanism 4 for controlling the contraction of the clamping strip 312 is provided in the exchange box 22. The reset mechanism 4 includes a second support plate 41, a lifting assembly 42 and a transmission assembly 43; the second support plate 41 is arranged on the movable plate 221; the lifting assembly 42 is arranged on the mounting seat 311, and the lifting assembly 42 is used for controlling the contraction of the clamping strip 312; the transmission assembly 43 is in transmission connection with the lifting assembly 42; in the working state, when the movable plate 221 moves towards the first side plate 224 and the second support plate 41 contacts the transmission assembly 43, the second support plate 41 drives the lifting assembly 42 through the transmission assembly 43, and the lifting assembly 42 controls the contraction of the clamping strip 312.

[0043] The present invention realizes the function of controlling the contraction of the card strip 312 so that the card strip 312 is inserted and matched with the docking groove 2212 through the second support plate 41, the lifting component 42 and the transmission component 43. After the mounting plate 222 is removed, the card strip 312 can be smoothly clamped with the movable plate 221. An inclined surface is provided on the transverse plate 2211. In order to enable the card strip 312 to have a cleaning effect and increase the stroke of the card strip 312, the card strip 312 can be abutted against the surface of the copper pipe 2221 under the elastic force of the first elastic member 313. However, the height of the transverse plate 2211 on the movable plate 221 is higher than that of the guide rail. When the movable plate 221 is pushed by the nitrogen spring 223 to the first side plate 224, the card strip 312 is in the extended state and the card strip 312 cannot be matched with the docking groove 2212 on the transverse plate 2211. Therefore, a reset mechanism 4 is provided. When the movable plate 221 moves towards the first side plate 224 under the elastic force of the nitrogen spring 223, the movable plate 221 drives the second support plate 41 to move. When the second support plate 41 contacts the transmission component 43, it pushes the transmission component 43, and then drives the lifting component 42 through the transmission component 43. The lifting component 42 controls the contraction of the card strip 312, so that the card strip 312 can contact the inclined surface on the transverse plate 2211. Then, during the movement of the movable plate 221, the card strip 312 is squeezed by the inclined surface on the transverse plate 2211, and the first elastic member 313 contracts under the squeezing force until the card strip 312 is matched with the docking groove 2212 on the transverse plate 2211, completing the movement restriction of the movable plate 221.

[0044] Refer to Figure 2 , Figure 5 and Figure 8 : The first control component 32 includes an insertion plate 321 and a push plate 322; the insertion plate 321 is slidably mounted on the first support plate 2222; the push plate 322 is connected to the insertion plate 321, and the push plate 322 is located on the side of the first support plate 2222 away from the mounting plate 222; in the working state, when the push plate 322 is subjected to a thrust force, the insertion plate 321 on the push plate 322 abuts against the extension platform 2223.

[0045] The present invention realizes the function of releasing the movement restriction of the fixing component 31 on the mounting plate 222 through the insertion plate 321 and the push plate 322. When disassembling the mounting plate 222, the operator pushes the push plate 322, and the push plate 322 drives the insertion plate 321 to move towards the extension platform 2223. When the insertion plate 321 contacts the card strip 312, it squeezes the card strip 312, and the first elastic member 313 contracts under the squeezing force, so that the card strip 312 is separated from the extension platform 2223, releasing the movement restriction of the fixing component 31 on the mounting plate 222. The movable plate 221 is pushed by the elastic force of the nitrogen spring 223, and transmits the thrust to the mounting plate 222, so that the movable plate 221 and the mounting plate 222 move away from the exchange box 22, facilitating the operator to remove the mounting plate 222.

[0046] Refer toFigure 5 and Figure 7 : The second control component 33 includes a push bar 331, a movable bar 332 and a second elastic member 333; both the push bar 331 and the movable bar 332 are slidably installed in the docking groove 2212 of the cross plate 2211; both ends of the second elastic member 333 are respectively connected to the push bar 331 and the movable bar 332; when the clamping bar 312 and the docking groove 2212 are in an inserted state and the mounting plate 222 abuts against the movable plate 221, the mounting plate 222 presses the movable bar 332, the movable bar 332 pushes the push bar 331 through the second elastic member 333, and the push bar 331 pushes the clamping bar 312 out of the docking groove 2212.

[0047] In the present invention, the push bar 331, the movable bar 332 and the second elastic member 333 automatically release the movement restriction of the fixing component 31 on the movable plate 221 when the mounting plate 222 is inserted. After the mounting plate 222 is removed, the clamping bar 312 and the docking groove 2212 on the cross plate 2211 are in an inserted state, and the fixing component 31 restricts the movement of the movable plate 221. Then the operator inserts the mounting plate 222. When the mounting plate 222 contacts the movable plate 221, the end of the mounting plate 222 presses the movable bar 332 on the cross plate 2211, the movable bar 332 pushes the push bar 331 through the second elastic member 333, and the push bar 331 pushes the clamping bar 312 after contacting the clamping bar 312. When the clamping bar 312 is separated from the docking groove 2212, the movement restriction of the fixing component 31 on the movable plate 221 is released, so that the mounting plate 222 can be smoothly inserted into the exchange box 22.

[0048] Refer to Figure 5 、 Figure 6 、 Figure 9 and Figure 10 : The lifting component 42 includes a connecting block 421 and a support 422; the connecting block 421 is connected to the clamping bar 312, a first rack 4211 is provided on the connecting block 421; the support 422 is arranged on the mounting seat 311, a rotating shaft 4221 is rotatably arranged on the support 422, a first rotating gear 4222 is sleeved on the rotating shaft 4221, the first rotating gear 4222 is meshed and connected with the first rack 4211, and the rotating shaft 4221 is in transmission connection with the transmission component 43.

[0049] The present invention realizes the function of controlling the lifting of the clamping strip 312 through the connecting block 421, the first rack 4211, the support 422, the rotating shaft 4221 and the first rotating gear 4222. When the movable plate 221 moves towards the first side plate 224 under the elastic force of the nitrogen spring 223, the movable plate 221 drives the second support plate 41 to move. When the second support plate 41 contacts the transmission assembly 43, it pushes the transmission assembly 43, and then drives the rotating shaft 4221 to rotate through the transmission assembly 43. The rotating shaft 4221 drives the first rotating gear 4222 to rotate. The first rotating gear 4222 drives the first rack 4211 to move. The first rack 4211 drives the clamping strip 312 to move through the connecting block 421, controlling the contraction of the clamping strip 312, so that the clamping strip 312 can contact the inclined surface on the cross plate 2211. Then, during the movement of the movable plate 221, the clamping strip 312 is squeezed by the inclined surface on the cross plate 2211, and the first elastic member 313 contracts under the squeezing force until the clamping strip 312 is engaged with the docking groove 2212 on the cross plate 2211, completing the movement restriction of the movable plate 221.

[0050] Refer to Figure 6 , Figure 9 and Figure 10 : The transmission assembly 43 includes a second rack 431, a third elastic member 432 and a second rotating gear 433; the second rack 431 is slidably mounted on the support 422, and an extension plate 4311 is provided at one end of the second rack 431 away from the support 422; both ends of the third elastic member 432 are connected to the extension plate 4311 and the support 422 respectively; the second rotating gear 433 is sleeved on the rotating shaft 4221, and the second rotating gear 433 is meshed with the second rack 431.

[0051] The present invention realizes the function of driving the lifting plate through the second rack 431, the third elastic member 432 and the second rotating gear 433. When the movable plate 221 moves towards the first side plate 224 under the elastic force of the nitrogen spring 223, the movable plate 221 drives the second support plate 41 to move. When the second support plate 41 contacts the extension plate 4311 of the second rack 431, it pushes the extension plate 4311, and the third elastic member 432 contracts under the squeezing force. The extension plate 4311 drives the second rack 431 to move. The second rack 431 drives the second rotating gear 433 meshed with it to rotate. The second rotating gear 433 drives the rotating shaft 4221 to rotate. The rotating shaft 4221 drives the first rotating gear 4222 to rotate. The first rotating gear 4222 drives the first rack 4211 to move. The first rack 4211 drives the clamping strip 312 to move through the connecting block 421, controlling the contraction of the clamping strip 312.

[0052] Refer to Figure 4 : The push plate 322 is provided with a second handle 323 and a fourth elastic member 324; both ends of the fourth elastic member 324 are connected to the push plate 322 and the first support plate 2222 respectively.

[0053] The present invention realizes the function of facilitating the operator to push and pull the push plate 322 through the second handle 323 and the fourth elastic member 324. When disassembling the mounting plate 222, the operator holds the second handle 323 and pushes the push plate 322 through the second handle 323. The fourth elastic member 324 contracts under the thrust, and then the insertion plate 321 is used to squeeze the clamping strip 312, so that the clamping strip 312 is separated from the extension table 2223. And after the disassembly is completed, the push plate 322 is reset under the elastic force of the fourth elastic member 324, so that the insertion plate 321 is separated from the extension table 2223, facilitating the insertion of the mounting plate 222 into the exchange box 22 again.

[0054] The above embodiments only represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
