Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically a drying device for filter cloth production. Background Technology

[0002] Filter cloth is a filter medium woven from natural or synthetic fibers. It is mainly used for air filtration, dust removal, and dust collection, thereby achieving the purpose of purifying the air and protecting the environment. It is widely used in industries such as metallurgy, chemical industry, dyeing, pharmaceuticals, and food.

[0003] Currently, the essential drying step in the production of filter cloth is completed by a dryer. Inside, multiple layers of guide rollers reciprocate to move and convey the filter cloth. Hot air generated by the hot air blower in the dryer passes through the filter cloth from bottom to top to dry it. The conveying stroke of the filter cloth is fixed, and the temperature and humidity of the output filter cloth are monitored and regulated entirely by temperature and humidity sensors and the power of the hot air blower. The regulation accuracy is low, and the hot air after drying is directly discharged, which also wastes heat energy.

[0004] Therefore, in order to solve the above problems, a drying device for filter cloth production is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for filter cloth production, which has higher temperature and humidity control accuracy and more efficient heat energy utilization, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drying device for filter cloth production includes a housing with an inlet on the bottom left and an outlet on the bottom right. A hot air blower is fixedly installed on the front of the housing. A first vertical partition is fixedly installed inside the housing, with a material passage at the top. The first vertical partition divides the housing into a preheating chamber on the left and a drying chamber on the right. A first horizontal partition is fixedly installed on the right side of the first vertical partition. A first rotating roller is rotatably installed inside the drying chamber, located to the right of the first horizontal partition. An adjustment assembly is provided inside the drying chamber, located below the first horizontal partition. A drive assembly for moving the adjustment assembly is provided on the right side of the housing. A uniformly distributed air outlet pipe is fixedly installed at the bottom of the drying chamber, and the output end of the hot air blower is connected to the uniformly distributed air outlet pipe. A hollow roller is rotatably installed inside the preheating chamber. A conveying assembly connecting the preheating chamber and the drying chamber is provided in the housing.

Second vertical partitions are fixedly installed on the upper and lower sides of the second transverse partition. The second transverse partition has a through groove, and a second rotating roller is rotatably installed in the through groove.

[0010] Furthermore, the upper end of the second vertical partition on the upper side is slidably assembled with the first horizontal partition, and the lower end of the second vertical partition on the lower side is slidably assembled with the first horizontal partition or the bottom of the drying chamber.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 2 This utility model provides a drying device for filter cloth production, including a box body 1. The bottom left side of the box body 1 has an inlet and the bottom right side has an outlet. A hot air blower 11 is fixedly installed on the front side of the box body 1. A first vertical partition 6 is fixedly installed inside the box body 1. A material passage is opened at the top of the first vertical partition 6. The first vertical partition 6 divides the box body 1 into a preheating chamber on the left and a drying chamber on the right. A first horizontal partition 10 is fixedly installed on the right side of the first vertical partition 6. The first horizontal partition 10 is horizontally arranged. A first rotating roller 2 is rotatably installed inside the drying chamber. The first rotating roller 2 is located to the right of the first horizontal partition 10. The first rotating roller 2 is used to change the conveying direction of the filter cloth. An adjustment component 5 is provided inside the drying chamber. The adjustment component 5 is located below the first horizontal partition 10. A drive component 3 for moving the adjustment component 5 is provided on the right side of the box body 1. The drive component 3 can move the adjustment component 5 left and right to change the conveying length of the filter cloth in the drying chamber.

[0024] A uniformly distributed air outlet duct 4 is fixedly installed at the bottom of the drying chamber. The output end of the hot air blower 11 is connected to the uniformly distributed air outlet duct 4. The hot air generated by the hot air blower 11 can be output from the uniformly distributed air outlet duct 4 and flow from bottom to top in the drying chamber, opposite to the conveying direction of the filter cloth, which can ensure drying efficiency. A hollow roller 7 is rotatably installed in the preheating chamber. The hollow roller 7 is used to press and convey the filter cloth. The box body 1 is provided with a conveying assembly 8 that connects the preheating chamber and the drying chamber. The conveying assembly 8 can introduce the hot air in the drying chamber into the hollow roller 7 to preheat the filter cloth that has just entered the preheating chamber, and utilize the residual heat in an isolated manner to save energy. In addition, a temperature and humidity sensor 9 is fixedly installed inside the box body 1. The temperature and humidity sensor 9 is used to monitor the temperature and humidity of the filter cloth at the outlet of the drying chamber to ensure the drying effect.

[0025] Specifically, the number of first horizontal partitions 10 is at least two that are evenly arranged in the vertical direction, and the number of corresponding first rotating rollers 2 is the same as the number of first horizontal partitions 10, and they are located on the right side, so that the length of the filter cloth being conveyed back and forth in the drying chamber can be set as needed.

[0026] Specifically, such as Figure 4 As shown, the adjusting assembly 5 includes a U-shaped guide plate 51 and a second transverse partition 52. Multiple pairs of U-shaped guide plates 51 are fixedly installed inside the drying chamber. Each pair of U-shaped guide plates 51 is located below the first transverse partition 10. A second transverse partition 52 is slidably installed between each pair of U-shaped guide plates 51. The right end of the second transverse partition 52 extends out of the drying chamber. A square opening for the second transverse partition 52 to pass through is provided on the right side of the drying chamber. Second vertical partitions 53 are fixedly installed on the upper and lower sides of the second transverse partition 52. A through groove 55 is provided, and a second rotating roller 54 is rotatably installed in the through groove 55. The through groove 55 is used to pass the filter cloth through and change the conveying direction of the filter cloth again through the second rotating roller 54. When the second horizontal partition 52 moves in the U-shaped guide plate 51, it can change the conveying distance of the filter cloth on the second rotating roller 54. Thus, the conveying length of the filter cloth in the drying chamber can be adjusted in time according to the temperature and humidity conditions to ensure that the drying efficiency is at its best. In addition, the second vertical partition 53 is set to block the space on the left side where there is no filter cloth being conveyed, so as to avoid the waste of heat energy.

[0027] Furthermore, the upper end of the upper second vertical partition 53 is slidably assembled with the first horizontal partition 10, and the lower end of the lower second vertical partition 53 is slidably assembled with the first horizontal partition 10 or the bottom of the drying chamber; for example, the adjusting component 5 located between the two first horizontal partitions 10 has the ends of the second vertical partitions 53 on both sides slidably assembled with the first horizontal partitions 10, which can isolate the left space; while the adjusting component 5 at the bottom is located between the first horizontal partition 10 and the bottom of the drying chamber, with the upper end of the upper second vertical partition 53 slidably assembled with the first horizontal partition 10, and the lower end of the lower second vertical partition 53 slidably assembled with the bottom of the drying chamber, which is also used to isolate the left space.

[0028] Specifically, such as Figure 5 As shown, the drive assembly 3 includes an electric cylinder 31 and a connecting rod 34. The same connecting rod 34 is fixedly installed on the right end of the second transverse partition 52. The electric cylinder 31 is horizontally fixedly installed on the right side of the housing 1. One end of the support rod 32 is rotatably installed on the push rod end of the electric cylinder 31. The other end of the support rod 32 is fixedly installed with a rotating sleeve 33. The rotating sleeve 33 is rotatably assembled with the connecting rod 34. When the electric cylinder 31 extends and retracts the push rod, it can move the connecting rod 34 left and right through the transmission of the inclined support rod 32 and the rotating sleeve 33, thereby completing the control of the adjustment assembly 5.

[0029] Specifically, such as Figure 3 As shown, the conveying assembly 8 includes a heat recovery pipe 81 and a heat input pipe 83. The front end of the hollow roller 7 is rotatably mounted with the same heat input pipe 83, and the rear end of the hollow roller 7 is rotatably mounted with the same exhaust pipe 84. The upper side of the drying chamber is connected to one end of the heat recovery pipe 81, and the other end of the heat recovery pipe 81 is connected to the heat input pipe 83 with an induced draft fan 82. When the induced draft fan 82 is working, it can introduce the hot air in the drying chamber into the hollow roller 7 through the heat recovery pipe 81 and the heat input pipe 83, preheat the filter cloth attached to the hollow roller 7, and then discharge it from the exhaust pipe 84, which can make full use of heat energy.

[0030] Working principle:

[0031] During operation, the filter cloth first enters the preheating chamber through the feed inlet on the left, and after being conveyed by multiple hollow rollers 7, it enters the drying chamber through the feed outlet. After being conveyed by the first rotating roller 2 and the second rotating roller 54 to increase the stroke, it is finally output from the discharge outlet on the right.

[0032] During the conveying process, the hot air generated by the hot air blower 11 is output through the evenly distributed air outlet duct 4. Due to the setting of the second horizontal partition 52, the second vertical partition 53 and the first horizontal partition 10, the air can be sent upward in an S-shape against the direction of filter cloth conveying to dry the filter cloth.

[0033] The conveying assembly 8 can introduce the dried hot air into the hollow roller 7 to preheat the filter cloth that is attached and conveyed on the hollow roller 7, and then discharge it from the exhaust pipe 84.

[0034] Meanwhile, the temperature and humidity sensor 9 is used to monitor the temperature and humidity of the filter cloth at the outlet of the drying chamber. When the temperature is low and the humidity is high, the output heat of the hot air blower 11 is increased, and the second horizontal partition 52 and the second rotating roller 54 are moved to the left via the drive assembly 3 to increase the travel of the filter cloth and the drying temperature. Conversely, when the temperature is high and the humidity is low, the output heat of the hot air blower 11 is reduced, and the second horizontal partition 52 and the second rotating roller 54 are moved to the right via the drive assembly 3 to reduce the travel of the filter cloth and the drying temperature, thereby keeping the temperature and humidity of the output filter cloth within the set range, which is beneficial for subsequent processing.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
