DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0026] The embodiment of the present application provides a base material drying equipment for fireproof water-repellent cloth production, which can solve the problem that in the related art, the heat received by each part of the cloth is uneven during the drying process of the fireproof water-repellent cloth, so that the drying effect is inconsistent.

[0027] Please refer to Figures 1-3 A base material drying equipment for fireproof water-repellent cloth production includes: a box body 1, the box body 1 has a drying cavity 2 inside, the box body 1 is provided with a discharging table 3 at both ends, the discharging table 3 is used for feeding and discharging cloth, a conveyor 4 arranged inside the drying cavity 2 is arranged between the two discharging tables 3, the conveyor 4 is used for conveying the cloth on one side of the discharging table 3 to the other side of the discharging table 3; the drying cavity 2 is provided with an air jet 5 for drying the cloth, the air jet 5 includes a plurality of annular pipes 51 arranged inside the drying cavity 2, the annular pipes 51 are sleeved outside the conveyor 4, and a plurality of air jet nozzles 52 are arranged on the inner side of the annular pipes 51; the box body 1 is further provided with an air supply part 6, and the air supply part 6 is used for providing hot air to the air jet 5.

[0028] First, the cloth to be dried is placed on the loading table 3 at one end of the device, then the conveyor 4 is started, the cloth is smoothly conveyed into the drying chamber 2, and moves along the path of the conveyor 4 to the other end. The design of the conveyor 4 ensures that the cloth can maintain a stable moving speed during the drying process, thereby improving the drying efficiency and uniformity.

[0029] When the cloth enters the drying chamber 2, the air jet 5 starts to work. The air jet 5 is composed of several annular pipes 51 distributed along the length direction of the drying chamber 2. These annular pipes are tightly fitted outside the conveyor 4. The inside of the annular pipe 51 is provided with several air nozzles 52, which are responsible for uniformly spraying hot air onto the cloth. The hot air comes from the air supply part 6, which provides continuous and stable hot air to the air jet 5.

[0030] After the hot air is sprayed onto the cloth through the air nozzles 52, it exchanges heat with the cloth, evaporating the moisture and solvent in the cloth. At the same time, since the annular pipe 51 is a rectangular pipe, it increases the contact area and uniformity of the hot air, ensuring that the cloth can be fully dried. During the drying process, the hot air circulates in the drying chamber, improving the utilization efficiency of heat energy. After sufficient drying, the cloth is conveyed to the loading table 3 at the other end of the device, completing the entire drying process.

[0031] Through the combined use of the annular pipe 51 and the air nozzle 52, uniform spraying of hot air and full drying of the cloth are achieved, improving the utilization efficiency of heat energy and shortening the drying time, thereby improving production efficiency. By uniformly covering the cloth with hot air, it can ensure that the cloth is uniformly heated during the drying process. This helps to avoid quality problems caused by local overheating or insufficient drying of the cloth.

[0032] In addition, the temperature of the hot air and the conveying speed can be adjusted according to production needs to adapt to the drying needs of cloth of different materials and thicknesses. This flexibility makes the device have a wide application prospect in the production process of fire-resistant and water-repellent cloth.

[0033] In this embodiment, several annular pipes 51 are distributed along the length direction of the drying chamber 2. The annular pipe 51 is a rectangular pipe, and the conveyor 4 extends along the inside of the annular pipe 51 at one end.

[0034] The annular pipes 51 are evenly distributed along the length direction of the drying chamber 2, ensuring that the hot air can be continuously and uniformly sprayed onto the cloth along the conveying path of the cloth, thereby achieving efficient drying effect. Each annular pipe 51 serves as an independent hot air spraying unit, which cooperates together to ensure uniform distribution of hot air in the entire drying chamber, avoiding local overheating or insufficient drying.

[0035] The annular pipe 51 is designed as a rectangular pipe. Firstly, the rectangular pipe has a larger contact area than the circular pipe, which means that the hot air can be in more sufficient contact with the cloth, thereby improving the drying efficiency. Secondly, the design of the rectangular pipe makes the flow of hot air in the pipe more stable, reducing the heat loss caused by turbulent airflow.

[0036] One end of the conveyor 4 extends along the inner side of the annular pipe 51 in turn. This design ensures that the cloth can be closely attached to the outer side of the annular pipe during transportation, thereby maximizing the use of hot air for drying. At the same time, this extension mode also maintains the stability and continuity of the conveyor, ensuring the smooth transportation of the cloth during the drying process.

[0037] Specifically, as shown in Figure 2 and Figure 5 , the air supply part 6 in the embodiment includes a shell 61, and the shell 61 is internally provided with a fan 62, a filter tank 63 and a heater 64 in turn. The air inlet of the fan 62 is in communication with the outside, the air outlet of the fan 62 is in communication with the filter tank 63, the other end of the filter tank 63 is connected with the heater 64 through a pipeline, and the other end of the heater 64 is provided with a conveying pipeline 65, which is in communication with a plurality of annular pipes 51.

[0038] The shell 61 is the main structure of the air supply part, and its main function is to protect the internal mechanical parts from external interference.

[0039] The fan 62 is the power source of the air supply part, and its air inlet is in communication with the outside, which can suck in the external air. When the fan 62 starts, it will produce a strong suction force to suck in the external air, and then deliver the air to the filter tank 63 through its air outlet.

[0040] The main function of the filter tank 63 is to filter out impurities and particles in the air to ensure that the hot air provided to the air jet 5 is clean and pollution-free. This helps to prevent the air jet nozzle 52 from being blocked, improves the drying efficiency, and also helps to protect the cloth from pollution. The filter tank usually contains a high-efficiency filter, such as a HEPA filter, which can filter out tiny particles in the air.

[0041] The heater 64 is one of the key components of the air supply part, and its function is to heat the filtered air to the required temperature. The heater usually adopts an electric heating method, which can adjust the heating power according to the production demand, thereby providing hot air of different temperatures. The heated hot air is delivered to the annular pipe 51 through the conveying pipeline 65 for drying the cloth.

[0042] The conveying pipeline 65 is a bridge connecting the heater 64 and the annular pipe 51, and its function is to ensure that the heated hot air can be smoothly and uniformly delivered to the air jet 5.

[0043] Specifically, when the fan 62 starts, it inhales external air and delivers it into the filter tank 63. After being filtered by the filter tank 63, the clean air is delivered into the heater 64 for heating. The heated hot air is delivered into the annular pipes 51 through the delivery pipeline 65 and is uniformly sprayed onto the cloth through the air nozzles 52, achieving the drying process. During the entire process, the fan 62, the filter tank 63, the heater 64, and the delivery pipeline 65 work together to ensure stable supply and efficient utilization of the hot air.

[0044] Further, as shown in Figure 1 and Figure 5 , the delivery pipeline 65 includes a main pipeline 651 arranged on the box body 1, the main pipeline 651 is in pipeline communication with the heater 64, and a plurality of shunt pipelines 652 are arranged on one side of the main pipeline 651 in sequence. The other end of each shunt pipeline 652 extends into the box body 1 and is in communication with one annular pipe 51.

[0045] The main pipeline 651 is the main part of the delivery pipeline 65, which is arranged on the box body 1 and is in pipeline communication with the heater 64. The main function of the main pipeline is to collect and transmit the heated hot air, ensuring that the hot air can be delivered from a centralized source, the heater 64, to each annular pipe 51 in the box body 1.

[0046] The shunt pipeline 652 is a component connecting the main pipeline 651 and the annular pipe 51, which extends from one side of the main pipeline in sequence and extends into the box body 1 at the other end, and is in communication with one annular pipe 51. The main function of the shunt pipeline is to uniformly distribute the hot air in the main pipeline to each annular pipe 51, ensuring that each annular pipe 51 can obtain sufficient hot air for drying treatment.

[0047] In one embodiment, the conveyor 4 is a chain conveyor.

[0048] In the base material drying equipment for producing fireproof and water-repellent cloth, the conveyor 4 is responsible for conveying the cloth to be dried from one end to the other end, so that it can uniformly and continuously pass through the drying cavity 2 and receive the drying treatment of the hot air.

[0049] The chain conveyor is composed of a chain and a driving device. The chain is usually made of high-strength alloy material and can withstand a large tension and load. This makes the chain conveyor have excellent stability and durability during conveying, and is particularly suitable for drying equipment that needs to be continuously operated for a long time.

[0050] The gap between the chains on the chain conveyor is also conducive to the circulation and distribution of hot air.

[0051] The design of the chain conveyor is flexible and can be customized according to different production needs. For example, the pitch, speed, and direction of the chain can be adjusted to accommodate different materials, thicknesses, and sizes of fabric. This is prior art and will not be repeated here.

[0052] In one embodiment, as shown in Figure 1 and Figure 6 , the feeding table 3 includes a table body 31, the upper part of which is provided with a U-shaped groove 32, and the conveyor 4 is arranged on the U-shaped groove 32. A plurality of guide rollers 33 are arranged on the side of the table body 31 away from the conveyor 4.

[0053] The table body 31 is the main structure of the feeding table, providing a stable support platform for placing the fabric to be dried.

[0054] The U-shaped groove 32 is used to accommodate and support the conveyor 4, allowing the conveyor 4 to be stably installed on the table body and ensuring that the fabric can maintain a smooth and continuous state during transportation.

[0055] The guide rollers 33 are distributed along the length of the table body to guide and support the fabric, ensuring that the fabric can smoothly enter the conveyor 4.

[0056] In this embodiment, the box body 1 is provided with a plurality of observation openings 11 on both sides, and the observation openings 11 are provided with explosion-proof glass.

[0057] The observation openings are arranged on both sides of the box body, which facilitates the operator to observe the inside of the box body from multiple angles. The number of observation openings is determined according to the size and internal layout of the box body to ensure that each corner of the box body can be observed comprehensively and clearly.

[0058] The glass installed on the observation opening is explosion-proof glass. Explosion-proof glass is a kind of glass that has been specially treated and has extremely high strength and impact resistance. Even in extreme cases of explosion or rupture, explosion-proof glass can maintain a certain degree of integrity and prevent debris from flying and injuring people, thereby ensuring the safety of the operator. The application of explosion-proof glass provides additional safety protection for the operator.
