Description

Technical Field

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

[0002] Liners are plates used to protect the surfaces of equipment or structures. They are usually installed inside the equipment or in specific parts of the structure, and serve functions such as wear resistance, impact resistance, heat insulation, sound insulation, and sealing. During the production and processing of liners, the surface of the liners usually needs to be cleaned, coated, and then dried.

[0003] However, existing liner surface drying equipment has the following problems: the method of directly blowing hot air onto the liner surface can easily lead to excessively high or low local temperatures on the liner surface, resulting in uneven drying and affecting the quality of the liner; the hot air utilization rate is low, and a large amount of heat is discharged without being fully utilized, resulting in energy waste; for thicker liner or liner with high moisture content, the drying time is long and the production efficiency is low. Therefore, a liner surface drying equipment is needed. Utility Model Content

[0004] The purpose of this invention is to provide a liner surface drying device that solves the problem of low liner drying efficiency in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liner surface drying device, comprising a drying box with through holes on both sides, a hot air furnace for providing hot airflow on the side of the drying box, the side wall of the hot air furnace being connected to a guide plate for guiding the airflow through an air supply pipe, a diffuser for diffusing the hot airflow at the bottom of the guide plate, an infrared heater for radiant heating in the middle of the bottom surface of the diffuser, a conveyor belt for conveying the liner inside the drying box, and clamps for holding the liner being provided oppositely on the outer wall of the conveyor belt.

[0006] Preferably, the guide plate, diffuser and infrared heater are symmetrically distributed about the midpoint of the air supply duct.

[0007] Preferably, a return air duct is installed on the top of the hot air furnace, and a circulating fan for recovering hot air flow is provided on the outer wall of the return air duct on the side away from the hot air furnace.

[0008] Preferably, a filter for filtering dust and impurities is installed at the other end of the return air duct.

[0009] Preferably, the inner wall of the conveyor belt is fitted with oppositely arranged conveyor rollers, and the outer wall of the drying box is equipped with a support plate that provides support. The outer wall of the support plate is provided with a rotary motor, which passes through the support plate and is connected to a set of conveyor rollers.

[0010] Preferably, the drying box has rubber brushes located at the upper and lower ends of the conveyor belt through the two side through holes to reduce the loss of hot airflow.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By placing the liner onto the conveyor belt and fixing it with clamps, a rotary motor drives the conveyor rollers to rotate, causing the conveyor belt to move the liner. The liner passes through a rubber brush and enters the interior of the drying chamber. At this time, a hot air furnace drives hot airflow through the air supply pipe, guide plate, and diffuser to blow air up and down the conveyor belt. Then, an external power source powers the infrared heater to improve drying efficiency. Simultaneously, a circulating fan drives the hot airflow inside the drying chamber to pass through a filter and be recycled through the return air pipe, completing the drying process.

Detailed Implementation

[0018] 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.

[0019] This utility model relates to a liner surface drying device, such as... Figure 1-4As shown, the drying chamber includes a drying box 1. The drying box 1 has through holes on both sides for the lining plate to pass through. A hot air furnace 2 is provided on the side of the drying box 1. The hot air furnace 2 generates hot air that flows into the interior of the drying box 1. The hot air furnace 2 is fixedly connected to a guide plate 4 located inside the drying box 1 through an air supply pipe 3.

[0020] Furthermore, diffuser covers 5 are provided on both sides of the bottom surface of the guide plate 4. The hot air flow from the air supply pipe 3 into the guide plate 4 is blown into the liner through the diffuser covers 5 to achieve the drying effect. An infrared heater 6 is also installed in the middle of the bottom surface of the diffuser cover 5. The infrared heating tube adopts medium wave or short wave infrared heating tube, which can directly radiate heat to the surface of the liner to improve the drying efficiency.

[0021] Among them, such as Figure 2 As shown, there are two sets of guide plates 4, diffuser 5 and infrared heaters 6. The positions of the two sets of guide plates 4, diffuser 5 and infrared heaters 6 are symmetrically distributed about the midpoint of the air supply duct 3. Undried lining plates can be further dried by the bottom set of equipment.

[0022] Furthermore, in order to improve drying efficiency, the top surface of the hot air furnace 2 is fixedly connected to one end of the return air duct 7, and the other end of the return air duct 7 passes through the side of the drying box 1 away from the hot air furnace 2, so that excess hot air flow inside the drying box 1 can be recovered and reused. A filter 9 is installed at one end of the return air duct 7 that passes through the drying box 1, so as to filter dust and impurities in the hot air. A circulating fan 8 is installed on the outer wall of the return air duct 7 on the side of the drying box 1 away from the hot air furnace 2, and the circulating fan 8 drives the recovery of hot air.

[0023] Furthermore, the drying chamber 1 is equipped with a conveyor belt 10 inside, which transports the liner. The inner wall of the conveyor belt 10 is fitted with conveyor rollers 11. There are two sets of conveyor rollers 11, which are respectively located at both ends of the inner wall of the conveyor belt 10. One end of one set of conveyor rollers 11 is fixedly connected to the output end of a rotary motor 12. The rotary motor 12 drives the conveyor rollers 11 to rotate the conveyor belt 10, causing the liner to move. The outer wall of the conveyor rollers 11 is rotatably connected to a support plate 13. The side wall of the support plate 13 is fixedly connected to the outer wall of the drying chamber 1 to support the movement of the conveyor rollers 11 and the conveyor belt 10. The side wall of the support plate 13 is fixedly connected to the end face of the rotary motor 12. The output end of the rotary motor 12 passes through the support plate 13 and is fixedly connected to the conveyor rollers 11.

[0024] Among them, such as Figure 4As shown, the clamp 14 includes a fixed frame 141, a push rod 142, a pressure plate 143, a spring 144, and a pull plate 145. The fixed frame 141 has a groove that matches the push rod 142. The push rod 142 can slide up and down into the groove of the fixed frame 141. The bottom end of the push rod 142 is fixedly connected to the top of the pressure plate 143. The pressure plate 143 and the fixed frame 141 are elastically connected by the spring 144. The top end of the push rod 142 is fixedly connected to the pull plate 145 above the fixed frame 141. Pulling the pull plate 145 causes the push rod 142 to lift the pressure plate 143. Releasing the pull plate 145 allows the pressure plate 143 to abut against the outer wall of the conveyor belt 10 by the elastic force of the spring 144. This clamps and fixes the liner to prevent unstable movement during drying. The fixed frame 141 is fixedly connected to the outer wall of the conveyor belt 10 by bolts.

[0025] Furthermore, rubber brushes 15 located outside the conveyor belt 10 are installed at the upper and lower ends of the through holes on both sides of the drying chamber 1. The rubber brushes 15 can reduce dust entering the drying chamber 1 and reduce the loss of hot airflow inside the drying chamber 1.

[0026] In practical use: the liner is placed on the conveyor belt 10 and fixed in place by the clamp 14. The rotary motor 12 drives the conveyor roller 11 to rotate, so that the conveyor belt 10 moves the liner. The liner passes through the rubber brush 15 and enters the interior of the drying chamber 1. At this time, the hot air furnace 2 drives the hot airflow through the air supply pipe 3, the guide plate 4 and the diffuser 5 to blow air up and down on the conveyor belt 10. Then, the infrared heater 6 is powered by external electricity to improve the drying efficiency. At the same time, the circulating fan 8 drives the hot airflow inside the drying chamber 1 to be filtered by the filter 9 and then passed into the return air pipe 7 for recycling, thus completing the drying process.
