Description

Technical Field

[0001] This utility model belongs to the field of textile cooling equipment, and specifically relates to a cooling device for a singeing machine. Background Technology

[0002] In textile production, singeing machines are used to remove fuzz from the surface of fabrics, improving fabric quality and reducing defects in subsequent dyeing and printing processes. To control the singeing effect and protect the fabric, the cold water rollers and burners within the singeing machine need to be cooled. Traditionally, cooling water is pumped into these systems and then drained. This method consumes a large amount of water. Furthermore, the water produces scale during heating, and the continuous addition of new cooling water increases scale buildup in the cold water rollers and burner cooling system, leading to increased maintenance costs. Singeing machine maintenance is also inconvenient, and frequent maintenance can negatively impact production efficiency.

[0003] To address the aforementioned issues, plate heat exchangers combined with circulating water tanks have begun to be used for cooling in the production field. By circulating cooling water within the plate heat exchanger and the singeing machine, new scale buildup in the singeing machine is effectively prevented, and cooling water consumption is reduced. Furthermore, the water used for cooling the plate heat exchanger is cooled again through the circulating water tank after heating, achieving water resource reuse. While using plate heat exchangers reduces the maintenance costs of the singeing machine, regular scale removal is still necessary in actual use. Because of the large number of heat exchange plates, cleaning requires disassembling each plate individually, making the process cumbersome. Moreover, when issues such as rubber aging or leakage occur, some plates need to be replaced. With existing plate heat exchangers, disassembling some heat exchange plates requires disassembling a large number of other plates as well, making maintenance very inconvenient. Patent CN211823984U discloses a plate heat exchanger that is easy to maintain. In this device, each heat exchange plate is connected to a pull ball, and the pull balls are connected by a pull ball fixing rope. When the outer plates are pulled, the remaining plates are also moved by the fixing rope and the pull balls, creating a certain gap between each heat exchange plate, facilitating cleaning. However, in practical applications, when it is necessary to replace some heat exchange plates, due to the restriction of the pull ball fixing rope, a large number of heat exchange plates must be removed from the rope before the plate to be replaced can be disassembled, making the disassembly and assembly process inconvenient. Therefore, there is an urgent need for a cooling device for plate heat exchangers that is easier to maintain. Utility Model Content

[0004] To overcome the shortcomings and problems of the existing technology, this utility model provides a cooling device for a singeing machine.

[0005] This utility model is achieved through the following technical solution:

[0006] A singeing machine cooling device includes a plate heat exchanger. The plate heat exchanger includes a front plate with a hot medium inlet, a hot medium outlet, a cold medium inlet, and a cold medium outlet. The hot medium inlet is connected to a first water inlet pipe, which is used to connect to the outlet of the singeing machine. The hot medium outlet is connected to a first water outlet pipe, which is connected to a water pump. The outlet end of the water pump is used to connect to the inlet of the singeing machine. The cold medium inlet is connected to a second water inlet pipe, and the cold medium outlet is connected to a second water outlet pipe. The plate heat exchanger also includes a support frame. A rear pressure plate is provided between the front plate and the support frame. A plurality of heat exchange plates are provided between the front plate and the rear pressure plate. A support rod assembly for supporting the heat exchange plates and the rear pressure plate is provided between the front plate and the support frame. A clamping screw is also connected between the front plate and the rear pressure plate.

[0007] The support rod assembly includes two first support rods and one second support rod. The two first support rods are respectively connected to both sides of the front end plate, and the second support rod is connected to the bottom of the front end plate. The ends of the first and second support rods are both connected to the upright frame.

[0008] A pull wire assembly is provided between the front end plate and the rear pressure plate to pull each heat exchange plate apart by a certain distance. The pull wire assembly includes a pull wire connected to the front end plate and the rear pressure plate at both ends, and a number of locking blocks are provided on the pull wire, each locking block being connected to a heat exchange plate.

[0009] Both sides of the heat exchange plate are provided with support ears, and the support ears are provided with slots. The slots are connected to the block, and the support ears also slide on the first support rod.

[0010] The card slot is provided in two places, and anti-detachment strips are also provided inside the card slots to prevent the card block from falling off.

[0011] A first pressure block is fixedly connected to the front end plate, and a second pressure block is fixedly connected to the rear pressure plate. Both the side of the first pressure block near the front end plate and the side of the second pressure block near the rear pressure plate are provided with pressure grooves.

[0012] Both the second inlet pipe and the second outlet pipe are equipped with pneumatic angle seat valves, and the second inlet pipe is also equipped with a Y-type filter.

[0013] It also includes a bracket, on which both the water pump and the plate heat exchanger are mounted.

[0014] The support is also equipped with a water supply container, the outlet of which is connected to the first water outlet pipe.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention includes a plate heat exchanger. The plate heat exchanger supports the heat exchange plates through the cooperation of support ears and support rod assemblies. Compared with traditional plate heat exchangers, the support rod assembly in this invention does not interfere with the disassembly and assembly of the heat exchange plates. When disassembling, the heat exchange plates can be directly pulled out from above the plate heat exchanger, while other plates remain stationary, greatly improving the efficiency of heat exchange plate disassembly and assembly. Simultaneously, the pull-wire assembly in this invention allows for quick spacing between each heat exchange plate, facilitating cleaning. Furthermore, the pull-wire assembly can be quickly connected to or disconnected from the heat exchange plates without affecting their disassembly and assembly. Attached Figure Description

Detailed Implementation

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 , 2 As shown, a singeing machine cooling device includes a support frame 100 and a plate heat exchanger 200. The plate heat exchanger 200 includes a front end plate 210, which has a hot medium inlet 211, a hot medium outlet 212, a cold medium inlet 213, and a cold medium outlet 214. The hot medium inlet 211 is connected to a first water inlet pipe 110, which is used to connect to the outlet of the singeing machine. The hot medium outlet 212 is connected to a first water outlet pipe 120, which is connected to a water pump 300. The outlet end of the water pump 300 is used to connect to the inlet of the singeing machine. After being heated, the cooling water in the singeing machine enters the plate heat exchanger 200 through the first water inlet pipe 110 for cooling, and then is pumped back into the singeing machine by the water pump 300. Through continuous circulation, uninterrupted cooling of the singeing machine can be achieved. The support 100 is also equipped with a water replenishment container 400, which is a water replenishment tank. The outlet of the water replenishment tank is connected to the first water outlet pipe 120. Because some of the cooling water will turn into water vapor and evaporate after being heated, it is necessary to replenish the cooling water. When the water pump 300 is working, the water in the water replenishment tank will be pumped into the first water outlet pipe 120 to replenish the cooling water.

[0027] like Figure 1 , 2 As shown, the cold medium inlet 213 is connected to a second water inlet pipe 130, and the cold medium outlet 214 is connected to a second water outlet pipe 140. Both the second water inlet pipe 130 and the second water outlet pipe 140 are connected to an external circulating water tank. The water used for cooling the plate heat exchanger 200 circulates continuously between the circulating water tank and the plate heat exchanger 200. By cooling the water in the circulating water tank, the normal operation of the plate heat exchanger 200 can be maintained, and water consumption can be effectively reduced. Both the second water inlet pipe 130 and the second water outlet pipe 140 are equipped with pneumatic angle seat valves 150. The pneumatic angle seat valves 150 can be closed to stop water circulation when maintaining the plate heat exchanger 200. The second water inlet pipe 130 is also equipped with a Y-type filter 160, which filters the cooling water used for cooling the plate heat exchanger 200, reducing the accumulation of impurities inside the plate heat exchanger 200.

[0028] like Figure 3 , 4As shown, the plate heat exchanger 200 also includes a support frame 220, and a rear pressure plate 230 is provided between the front end plate 210 and the support frame 220. A plurality of heat exchange plates 250 are provided between the front end plate 210 and the rear pressure plate 230, and a clamping screw 231 is also connected between the front end plate 210 and the rear pressure plate 230. By tightening the nut connected to the end of the clamping screw 231, the rear pressure plate 230 is pressed towards the front end plate 210, thereby fixing the heat exchange plates 250 between the front end plate 210 and the rear pressure plate 230, so as to realize the normal operation of the plate heat exchanger 200. A support rod assembly 240 for supporting the heat exchange plate 250 and the rear pressure plate 230 is provided between the front end plate 210 and the upright frame 220. The support rod assembly 240 includes two first support rods 241 and one second support rod 242. The two first support rods 241 are respectively connected to both sides of the front end plate 210, and the second support rod 242 is connected to the bottom of the front end plate 210. The ends of the first support rods 241 and the second support rod 242 are both connected to the upright frame 220.

[0029] like Figure 3 , 4 As shown, a support frame is formed between the front end plate 210, the support rod assembly 240, and the upright frame 220 to support the heat exchange plate 250 and the rear pressure plate 230. Simultaneously, the heat exchange plate 250 and the rear pressure plate 230 can move on the support rod assembly 240 to facilitate cleaning and disassembly of the heat exchange plate 250. Support ears 251 are provided on both sides of the heat exchange plate 250, and these ears slide on the first support rods 241. The two first support rods 241 support the two support ears 251 respectively. The second support rod 242 supports the bottom of the heat exchange plate 250. The support rod assembly 240 does not restrict the upward movement of the heat exchange plate 250. When the rear pressure plate 230 is not pressed down, the heat exchange plate 250 can be directly pulled upwards, facilitating the replacement of the heat exchange plate 250.

[0030] like Figure 4 , 5As shown in Figures 6 and 7, a pull wire assembly 260 is provided between the front end plate 210 and the rear pressure plate 230 to pull each heat exchange plate 250 apart by a certain distance. The pull wire assembly 260 includes a pull wire 261 connected to the front end plate 210 and the rear pressure plate 230 at both ends, and a plurality of locking blocks 262 are provided on the pull wire 261, each locking block 262 being connected to a heat exchange plate 250. By pulling the end of the pull wire 261, the pull wire 261 can drive the heat exchange plate 250 to move through the locking blocks 262. The support ear 251 is provided with two locking slots 252, and the locking blocks 262 are connected to the locking slots 252. An anti-detachment strip 263 is also provided in the locking slot 252 to prevent the locking blocks 262 from falling off. The two ends of the anti-detachment strip 263 are connected to the front end plate 210 and the upright frame 220 respectively, and the anti-detachment strip 263 can prevent the locking blocks 262 from falling off accidentally. When cleaning the heat exchange plates 250 is required, simply remove the clamping screw 231, pull the rear pressure plate 230 backward along the support rod assembly 240, and the pull wire 261 and the locking block 262 will separate each heat exchange plate 250 by a certain distance. Then, the heat exchange plates 250 can be directly rinsed and cleaned. The cooperation between the slot 252 and the locking block 262 will not affect the disassembly and assembly of the heat exchange plates 250. When it is necessary to disassemble some heat exchange plates 250, remove the anti-detachment strip 263 and the clamping screw 231, and then remove the locking block 262 connected to the corresponding heat exchange plate 250 from the slot 252. The heat exchange plate 250 can then be pulled out normally from above.

[0031] like Figure 3 , 7 As shown, a first pressure block 264 is fixedly connected to the front end plate 210, and a second pressure block 2641 is fixedly connected to the rear pressure plate 230. Both the side of the first pressure block 264 near the front end plate 210 and the side of the second pressure block 2641 near the rear pressure plate 230 are provided with pressure grooves 265. The first pressure block 264 and the second pressure block 2641 press the two ends of the pull wire 261 together through the pressure grooves 265, so that the rear pressure plate 230 can pull the pull wire 261 and keep the pull wire 261 fixed. The pull wire 261 is a steel wire, and the clamping block 262 is made of metal. Both can be used in high-temperature environments. The clamping block 262 is formed by directly pressing metal onto the pull wire 261 during the production process, therefore, the clamping block 262 and the pull wire 261 have high stability.

[0032] It should be noted that existing heat exchange plates have numerous protrusions pressed onto their surfaces during production. These protrusions primarily guide and restrict media flow, align rubber pads, and improve heat exchange efficiency. Rubber pads are also placed between adjacent heat exchange plates. Due to the influence of the rubber pads and protrusions, there is a certain gap between adjacent heat exchange plates. The heat exchange plate 250 in this embodiment is an improvement upon existing heat exchange plates and is produced using the same process. Both are formed from a single metal sheet through cutting and pressing. Therefore, the gap between adjacent heat exchange plates 250 provides space for the connection between the clamping block 262 and the heat exchange plate 250. Furthermore, because the heat exchange plate 250 is relatively thin, typically 0.4 to 1 mm, the clamping block 262 in this embodiment can be made thinner in practical applications without affecting the normal pressing connection between the heat exchange plates 250. In this embodiment, there are two slots 252. After the heat exchange plates 250 are arranged, the card block 262 and the heat exchange plate 250 can be connected by alternating up and down, so that the installation of the card block 262 requires less spacing between the heat exchange plates 250.

[0033] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
