Description

Technical Field

[0001] This utility model relates to the technical field of titanium plate processing equipment, and in particular to a device for blowing and dust removal from the surface of titanium strip coils for plate heat exchangers. Background Technology

[0002] Plate heat exchangers used in nuclear power plants have very high requirements for the surface of the finished titanium strip coils. However, the surface of the finished titanium strip coils is usually covered with a large amount of fine dust, making it difficult to meet the usage requirements. In addition, when the titanium strip coils undergo the stretching and straightening process, the fine dust on the surface of the titanium strip coils will adhere to the straightening rollers. As a result, when the rollers apply pressure to the titanium strip coils, it will cause defects such as black spots and bumps on the surface of the titanium strip coils, affecting the surface quality of the titanium strip coils. In order to improve the surface quality of the titanium strip coils, the rollers need to be cleaned and polished to reduce the defects on the surface of the titanium strip coils. However, polishing the rollers will affect the production efficiency. At the same time, the increase in the number of polishing times will also lead to changes in the size of the rollers, requiring replacement and increasing the consumption of auxiliary materials.

[0037] Reference Figures 1 to 4 This utility model discloses a device for blowing away dust from the surface of a titanium strip coil in a plate heat exchanger. The device includes a conveying platform 100, a dust collection bin 200, and a blowing pipe 300. The conveying platform 100 conveys the titanium strip coil, the blowing pipe 300 blows away dust from the surface of the titanium strip coil, and the dust collection bin 200 collects the dust blown away by the blowing pipe 300, thereby reducing the environmental impact of dust. Specifically, refer to... Figure 1 , Figure 4 As shown, baffles 110 are provided on both sides of the conveying platform 100 in the width direction, and the baffles 110 have through holes 111 penetrating through the baffles 110; the dust collection bin 200 is connected to the baffles 110 and communicates with the through holes 111; the blowpipe 300 is installed above the conveying platform 100 for supplying air to the surface of the titanium strip roll; both ends of the blowpipe 300 are connected to the air supply device through air supply pipes 310, and the middle part of the blowpipe 300 extends in the opposite direction to the conveying direction of the titanium strip roll to blow the dust on the titanium strip roll to both sides of the conveying platform 100 in the width direction, so that the dust enters the dust collection bin 200 through the through holes 111. (Refer to...) Figure 1As shown, the blowpipe 300 is V-shaped, which allows for better and more uniform blowing from the center of the titanium strip roll to both sides. This embodiment of the utility model provides a device for blowing dust off the surface of titanium strip rolls in a plate heat exchanger. The device is installed before the titanium strip roll enters the stretching and straightening process. By installing the blowpipe 300 above the conveying platform 100 to blow dust off the surface of the titanium strip roll, it effectively reduces the amount of dust adhering to the surface, thereby reducing the probability of dust adsorbed on the rollers causing defects on the surface of the titanium strip roll, reducing the number of roller grinding cycles, improving production efficiency, reducing the frequency of roller replacement, and reducing the loss of auxiliary materials. The blowpipe 300 blows the dust on the titanium strip roll to both sides of the width of the conveying platform 100, allowing the dust to enter the dust collection bin 200 through the through-hole 111, facilitating dust collection and reducing the environmental impact of flying dust.

[0038] The device for blowing and removing dust from the surface of a titanium strip coil in a plate heat exchanger, as described in this embodiment, further includes a detection structure 400. The detection structure 400 detects the position of the titanium strip coil and sends a position signal. An air supply device then supplies air to the blow pipe 300 based on the position signal. Specifically, refer to... Figure 1 , Figure 4 As shown, the detection structure 400 includes a signal generator 410 and a signal receiver 420. The signal generator 410 is mounted on the baffle 110, and the signal receiver 420 is mounted on the conveying platform 100. When the titanium strip roll passes through the conveying platform 100, the signal receiver 420 receives the signal sent by the signal generator 410, and the detection structure 400 sends a position signal. The air supply device is activated according to the position signal to supply air to the purge pipe 300 through the air supply pipe 310. For example, the signal generator 410 can emit a laser signal, and the signal receiver 420 can receive the laser signal. The signal generator 410 sends signals to the signal receiver 420 at set time intervals. When the signal receiver 420 can continuously receive the signals sent by the signal generator 410, it means that there is no obstruction between the signal receiver 420 and the signal generator 410, which also means that the titanium strip roll has not yet moved between the signal generator 410 and the signal receiver 420. If the signal receiver 420 does not receive the signals sent by the signal generator 410 within the set time period, it means that the titanium strip roll has moved between the signal generator 410 and the signal receiver 420. It is conceivable that by using the signal generator 410 and the signal receiver 420 in this embodiment to detect the position of the titanium strip roll, the air supply device can start supplying air to the purge pipe 300 when the titanium strip roll enters the detection structure 400. After the titanium strip roll has completely passed through the detection structure 400, the air supply device stops supplying air to the purge pipe 300 after a set delay. The air supply device delivers air to the blow pipe 300 according to the position signal, which can automatically blow away the dust on the surface of the titanium strip roll, improve efficiency, and reduce labor costs.

[0039] In an embodiment of this utility model, the dust collection bin 200 includes a bin body 210 and a connecting portion 220, the connecting portion 220 communicating with the bin body 210; the bin body 210 is disposed below the conveying platform 100, and the connecting portion 220 extends upward to connect with the baffle 110. Specifically, refer to... Figure 2 , Figure 4 As shown, the connecting part 220 extends upward and is connected to the baffle 110 by fasteners, such as bolts. The connecting part 220 is hollow inside, as is the hopper body 210. The hopper body 210 has two connecting parts 220, each connected to one of the two baffles 110. Each of the two connecting parts 220 has a connecting hole on its opposite side to align with the through hole 111. The hopper body 210 is positioned below the conveying platform 100, facilitating dust collection and making efficient use of the space below the conveying platform 100.

[0040] In an embodiment of this utility model, a fan 211 is installed at the bottom of the hopper 210, and a filter bag 230 is installed at the outlet end of the fan 211. The filter bag 230 is used to collect dust. Specifically, refer to... Figure 2 As shown, the bottom of the chamber 210 has a through hole, and the fan 211 is installed at the through hole. After the fan 211 is started, air enters through the connection hole of the connection part 220 and is then sent into the filter bag 230. The filter bag 230 has small pores, allowing air to pass through and collecting dust. Installing the fan 211 inside the chamber 210 facilitates the intake of dust into the chamber 210, further reducing the environmental impact of dust dispersion.

[0041] In an embodiment of this utility model, the filter bag 230 and the chamber 210 are detachably connected. Specifically, refer to... Figure 2 , Figure 3 As shown, the bottom of the chamber 210 is provided with a groove 212, and the top of the filter bag 230 is provided with a sliding strip 231. The sliding strip 231 is slidably installed in the groove 212 to connect the filter bag 230 and the chamber 210. The filter bag 230 and the chamber 210 are detachably connected, which facilitates the replacement of the filter bag 230.

[0042] In an embodiment of this utility model, the device for blowing and removing dust from the surface of a titanium strip coil in a plate heat exchanger further includes a cleaning structure 500, which is used to clean impurities from the surface of the titanium strip coil; the cleaning structure 500 and the blowing pipe 300 are arranged sequentially along the conveying direction of the titanium strip coil. For example, using... Figure 1 For example, the titanium strip roll is conveyed from left to right. Along the conveying direction of the titanium strip roll, the cleaning structure 500 is positioned in front of the blow pipe 300. The cleaning structure 500 is used to clean away dust on the surface of the titanium strip roll that cannot be removed by blowing. Simultaneously, referring to... Figure 1As shown, the cleaning structure 500 can also block the dust blown out by the blowpipe 300, so that the blown dust can better enter the dust collection bin 200. (Refer to...) Figure 1 , Figure 4 As shown, the cleaning structure 500 includes a mounting plate 510 and a cleaning brush 520. The mounting plate 510 is mounted on the baffle 110, and the cleaning brush 520 is mounted on the mounting plate 510 and extends toward the conveying platform 100. The mounting plate 510 and the cleaning brush 520 are detachably connected, for example by means of snap-fit, so as to facilitate the maintenance and replacement of the cleaning brush 520.

[0043] In this embodiment of the invention, the purge pipe 300 is provided with multiple air outlets at intervals. The diameter of the air outlets increases sequentially from the end to the middle of the purge pipe 300; that is, the air outlet at the end of the purge pipe 300 closer to the air supply pipe 310 is smaller, and the air outlet at the end farther from the air supply pipe 310 is larger. It is conceivable that for dust in the middle of the titanium strip roll, a greater airflow is required to blow the dust into the dust collection chamber 200. Therefore, the larger the air outlet is closer to the middle of the purge pipe 300, the better it can blow dust from various locations on the titanium strip roll into the dust collection chamber 200.

[0044] In this embodiment of the invention, the diameter of the purge pipe 300 decreases linearly from its end to its middle. Specifically, this design allows more airflow to be concentrated in the middle of the purge pipe 300, and combined with the larger air outlet in the middle of the purge pipe 300, it can better blow dust from various locations on the titanium strip roll into the dust collection chamber 200.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
