Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, and in particular to a drying device for paper product processing. Background Technology

[0002] Paper product processing refers to the process of turning pulp into various paper products, such as paper, cardboard, and paper bags, through a series of processes. Among these, drying is a crucial step in the paper product processing. It removes moisture from the pulp, giving the paper a certain strength and stability. Hot air drum drying involves hot air flowing from the tail end forward, making full contact with the paper and fully utilizing heat transfer through heat conduction, convection, and radiation. The heat energy is directly transferred to the paper, causing the moisture in the paper to evaporate continuously within the drum.

[0003] Currently, during the drying process of paper products, water vapor tends to accumulate at the top of the equipment. Over time, this water vapor gradually cools and condenses into water droplets, eventually dripping onto the paper surface. This process not only causes the paper to become wet again but also seriously affects the quality of paper drying, which may in turn affect subsequent production processes and the overall performance of the finished product. Therefore, there is an urgent need for a drying device for paper product processing to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for paper product processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drying apparatus for paper product processing includes a drying chamber, wherein a conveying mechanism for conveying paper products is provided inside the drying chamber, and a collection mechanism for collecting water vapor during the drying process is provided at the top of the interior of the drying chamber.

[0007] The collection mechanism includes a water collection hood fixed to the top of the drying chamber. The outer wall of the water collection hood is inclined around its perimeter. Condensation pipes are installed around the inner wall of the water collection hood. Inverted V-shaped water guide grooves are fixed on both sides of the top of the inner wall of the water collection hood. Positive V-shaped water guide grooves are fixed at both ends of the top of the inner wall of the drying chamber, with the inverted V-shaped water guide grooves located above the positive V-shaped water guide grooves. Water collection boxes are fixed at the top of both ends of the drying chamber. The bottoms of the two positive V-shaped water guide grooves are connected to communicating conveying pipes. The other ends of the two conveying pipes are respectively connected to the top of one end of the two water collection boxes and communicate with each other. Water droplets flow through the inner wall of the water collection hood into the inverted V-shaped water guide grooves, and then the inverted V-shaped water guide grooves guide the water droplets into the positive V-shaped water guide grooves.

[0008] Preferably, the bottom of the other end of the two water collection boxes is connected to a drain pipe, and a valve is provided inside the drain pipe.

[0009] Preferably, one end of the conveying pipe is provided with a filter screen, and the outer wall of the connection between the conveying pipe and the positive V water guide channel is provided with a rubber sealing ring.

[0010] Preferably, the conveying mechanism includes a roller conveyor, and both ends of the drying box have interconnected inlets and outlets at their bottoms. The roller conveyor passes through the inlets and outlets, and the paper products are placed on the roller conveyor, which then conveys the paper products into the drying box for drying.

[0011] Preferably, a fan heater is installed on the top of one side of the inner wall of the drying box, and the same mounting plate is fixed to the bottom of the inner walls at both ends of the drying box. The mounting plate is located below the roller conveyor. The top and bottom of the mounting plate are provided with communicating mounting grooves, and heating rods are installed inside the mounting grooves. The heating rods and the fan heater can heat the paper products evenly.

[0012] Preferably, an installation cylinder is fixed to the bottom of the inner wall of the drying box, and the bottom of the installation cylinder is located at the bottom of the drying box. A fan is installed inside the installation cylinder, which can blow the heat generated by the heating rod onto the paper products to accelerate their drying time.

[0013] Preferably, a dustproof mesh plate is installed on the bottom of the inner wall of the mounting cylinder.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of a collection mechanism, when water vapor comes into contact with the condenser tube in the inner wall of the water collection hood, it will be cooled and condensed into water droplets. Through the inclined state of the inner wall of the water collection hood, the water droplets can be guided into the inverted V water guide groove and the positive V water guide groove, and then transported to the interior of the water collection box through the conveying pipe. This achieves the collection of water vapor, preventing it from dripping onto the surface of paper products and causing them to be re-wetted. This helps to maintain the dryness and quality of paper products and improves the drying quality of paper products. Attached Figure Description

[0023] Reference Figure 1-5 A drying device for paper product processing includes a drying box 1, a conveying mechanism for conveying paper products inside the drying box 1, and a collection mechanism for collecting water vapor during the drying process at the top of the inside of the drying box 1.

[0024] The collection mechanism includes a water collection hood 2 fixed to the top of the drying oven 1. The outer wall of the water collection hood 2 is inclined, which allows for better guidance of water vapor. Condensation pipes 202 are installed around the inner wall of the water collection hood 2, which quickly cool the water vapor and condense it into water droplets. Inverted V-shaped water guide grooves 203 are fixed to both sides of the top of the inner wall of the water collection hood 2, and positive V-shaped water guide grooves 204 are fixed to both ends of the top of the inner wall of the drying oven 1. The inverted V-shaped water guide channel 203 is located above the positive V-shaped water guide channel 204. Water droplets will flow into the inverted V-shaped water guide channel 203 through the inner wall of the water collection hood 2. Then, the inverted V-shaped water guide channel 203 can guide the water droplets into the positive V-shaped water guide channel 204. Water collection boxes 201 are fixed at the top of both ends of the drying box 1. The bottom of the two positive V-shaped water guide channels 204 are connected to the communicating conveying pipes 207. The other end of the two conveying pipes 207 is connected to the top of one end of the two water collection boxes 201 respectively and communicates with them.

[0025] In this utility model, the bottom of the other end of the two water collection boxes 201 is connected to a drain pipe 205. The drain pipe 205 is equipped with a valve 206. By connecting the external water pipe to the drain pipe 205, the water collected in the water collection box 201 can be discharged.

[0026] In this utility model, a filter screen 209 is provided at one end of the conveying pipe 207, and a rubber sealing ring 208 is provided on the outer wall of the connection between the conveying pipe 207 and the positive V water guide groove 204.

[0027] In this utility model, the conveying mechanism includes a roller conveyor 3. Both ends of the drying box 1 have interconnected inlets and outlets 101 at their bottoms, and the roller conveyor 3 passes through the inlets and outlets 101. Paper products are placed on the roller conveyor 3, and then the roller conveyor 3 will convey the paper products into the interior of the drying box 1 for drying.

[0028] In this utility model, a fan heater 403 is installed on the top of one side of the inner wall of the drying box 1. The same mounting plate 4 is fixed on the bottom of the inner walls at both ends of the drying box 1. The mounting plate 4 is located below the roller conveyor device 3. The top and bottom of the mounting plate 4 are provided with communicating mounting grooves. A heating rod 401 is installed inside the mounting groove. The heating rod 401 and the fan heater 403 can heat the paper products evenly.

[0029] In this utility model, an installation cylinder 402 is fixed to the bottom of the inner wall of the drying box 1, and the bottom of the installation cylinder 402 is located at the bottom of the drying box 1. A fan 405 is installed inside the installation cylinder 402. The fan 405 can blow the heat generated by the heating rod 401 onto the paper products to accelerate their drying time.

[0030] In this utility model, a dustproof mesh plate 404 is installed on the bottom of the inner wall of the mounting cylinder 402.

[0031] Working Principle: In operation, the paper products to be dried are first placed on the roller conveyor 3. The controller then operates the roller conveyor 3, which conveys the paper products. Once inside the roller conveyor 3, it stops. The fan heater 403 and heating rod 401 are then activated to heat and dry the paper products. The controller then operates the fan 405, which blows the heat generated by the heating rod 401 onto the paper products, accelerating the drying process. After drying, the roller conveyor 3 is restarted to transport the paper products out of the drying chamber 1. During the drying process, water vapor is generated, which is blown towards the top of the drying chamber 1 by the fan 405. The water vapor then collects on the inner wall of the water collection hood 2. At this time, the water vapor comes into contact with the condenser 202, which cools the water vapor and condenses it into water droplets. Since the outer and inner walls of the water collection hood 2 are inclined, the condensed water droplets will drip into the inverted V-shaped water guide trough 203 through the guide of the inner wall of the water collection hood 2. Due to the shape of the inverted V-shaped water guide trough 203, the water will flow to both ends of the inverted V-shaped water guide trough 203 and flow into the positive V-shaped water guide trough 204. Then, it will flow into the water collection box 201 through one end of the delivery pipe 207 for collection. The filter screen 209 will filter the water to prevent blockage of the delivery pipe 207. When a certain amount of water is collected inside the water collection box 201, it is connected to one end of the drain pipe 205 through an external water pipe, and then the valve 206 is opened to drain the water inside the water collection box 201.
