[0005] The width of the existing dryer is about 4 meters. The materials are loaded manually or by multiple loading mechanisms arranged side by side, which is time-consuming and labor-intensive, occupies a large area, and increases the investment cost. At the same time, the condensed water generated during drying will also be in the hot air, and the materials are difficult to dry. Therefore, a dehumidification mechanism is installed to discharge the condensed water through the dehumidification mechanism, but at the same time, air needs to be added to the dryer. However, the added air is cold air from the outside. When the cold air from the outside enters the dryer, the drying temperature will drop. It takes a certain amount of time for the temperature in the dryer to reach the set temperature. In this way, the drying takes a long time, the energy consumption is high, and the work efficiency is low. In addition, the long net of the dryer is installed inside the dryer, and there are debris stuck on the net surface, which needs to be stopped for manual cleaning, which is time-consuming and labor-intensive.

[0031] like Figures 1 to 7 A continuous intelligent multi-purpose fourdrinier dryer is shown, comprising

[0032] The feeding mechanism 2 is used for initially dehumidifying the material, and a dehumidifying mechanism is provided on the feeding mechanism 2;

[0033] The vibrating swing feeder 1 is installed at the feeding end of the feeding mechanism 2 to uniformly vibrate the material and feed it into the feeding mechanism 2;

[0034] The drying section is installed at the discharge end of the feeding mechanism 2, and is composed of a plurality of dryers 3, and is used to dry the material. A dehumidification fan 4 is installed at the top of the drying section, and a waste heat recovery component 5 is installed at the top of each dryer 3. The steam heat exchanger in the drying section is connected to the waste heat recovery component 5 through a pipeline;

[0035] A chain plate assembly 10 is installed in the feeding mechanism 2 and the drying section;

[0036] The unloading mechanism 6 is installed at the discharging end of the drying section.

[0037] A cooling mechanism 23 for cooling the dried material is installed between the drying section and the unloading mechanism 6. The function of the cooling mechanism 23 is to reduce the temperature of the material, prevent overheating and solidification, provide operability and realize heat recovery, so as to protect the quality of the material, facilitate operation and subsequent processing, and improve energy utilization efficiency.

[0038] like Figure 4 As shown, the unloading mechanism 6 includes a unloading frame 11, a first crushing mechanism 7 is installed at the upper end of the unloading frame 11, a cleaning scraper mechanism 9 is installed in the middle section of the unloading frame 11, a unloading spiral mechanism 12 is installed at the lower end of the unloading frame 11, and a second crushing mechanism 8 is installed above the unloading spiral mechanism 12. The first crushing mechanism 7 is located above the discharge end of the chain plate assembly 10, and the first crushing mechanism 7 is in contact with the material on the long net of the chain plate assembly 10. The cleaning scraper mechanism 9 is located below the discharge end of the chain plate assembly 10, and the cleaning scraper mechanism 9 is in contact with the mesh surface of the long net of the chain plate assembly 10.

[0039] The cleaning scraper mechanism 9 includes a cleaning motor 24, a cleaning scraper bracket 25 is installed at the output end of the cleaning motor 24, an adjustment hole is opened at the end of the cleaning scraper bracket 25, a scraper 26 is installed on the cleaning scraper bracket 25 through the adjustment hole, and the working surface of the scraper 26 is inclined to further improve the cleaning efficiency. At the same time, the scraper 26 is a rubber scraper, which will not cause damage to the long net after long-term use, and can also clean the long net well.

[0040] like Figure 5 As shown, the waste heat recovery component 5 includes an automatic air valve 13, a metal radiator 14 is provided at the upper end of the automatic air valve 13, a water inlet pipe 16 is installed on one side of the metal radiator 14, the water inlet pipe 16 is connected to the steam trap 18 through a pipeline, and a water outlet pipe 17 is installed on the other side of the metal radiator 14, and the water outlet pipe 17 is connected to the water tank through a pipeline.

[0041] In addition, a metal primary filter 15 for filtering external cold air is installed above the metal radiator 14 .

[0042] An air inlet 19 is provided at the top of the dryer 3 , and an automatic air valve 13 is installed on the air inlet 19 .

[0043] like Figures 6-7 As shown, the vibrating swing feeder 1 includes a vibrating screen 20 and a swing motor 21, the vibrating screen 20 is installed on the swing motor 21, the vibrating screen 20 is an eccentric vibrating screen, and a long arm guide plate 22 is installed at the discharge port of the vibrating screen 20, and the discharge port of the long arm guide plate 22 is located on the long net in the chain plate assembly 10 in the feeding mechanism 2.

[0044] The long arm guide plate 22 swings in the width direction of the long net in the chain plate assembly 10 with the vibrating screen 20 as the center line, that is, Figure 7 As shown, it can be seen that the swinging range of the upper arm guide plate 22 is the width of the long net in the chain plate assembly 10. The material is fed onto the long net according to the swinging angle and is evenly laid on the net surface of the long net, so that the net surface in the width direction of the long net is covered with material, thereby improving the material drying efficiency.

[0045] At the same time, there is an expansion gap between the feeding mechanism 2 and the drying part, and there is also an expansion gap between the cooling mechanism 23 and the unloading mechanism 6. The expansion gap is mainly to adapt to the linear thermal expansion of the material during the drying process.

[0046] During the drying process, the material will expand due to the heat at high temperature, and the vibrating feeder 1 and the drying section are usually composed of different equipment, so there is a certain connection between the two. If no expansion gap is set, when the material expands, stress may be generated, causing deformation, rupture or even damage to the equipment. By setting the expansion gap, the vibrating feeder 1 and the drying section can be allowed to produce a certain displacement and expansion during the drying process to reduce the stress between the equipment. When the material expands, the expansion gap can provide a certain space so that the equipment can deform freely, reducing the concentration of stress.

[0047] In addition, the expansion gap between the vibrating swing feeder 1 and the drying section can also facilitate maintenance and cleaning. During the drying process, some materials or dust may accumulate at the interface between the devices, and the expansion gap can make cleaning and maintenance work more convenient and efficient.

[0048] Therefore, the expansion gap between the vibrating swing feeder 1 and the drying section is provided to accommodate the linear thermal expansion generated during the drying process of the material, reduce stress concentration, and facilitate maintenance and cleaning of the equipment.

[0049] Working process:

[0050] Step 1: Pour the material into the vibrating screen 20, start the swing motor 21 in the vibrating swing feeder 1, drive the eccentric vibrating screen 20 installed thereon to start vibrating and swinging, and evenly lay the material on the long mesh surface of the chain plate assembly 10 in the inner cavity of the feeding mechanism 2, and make the long mesh surface evenly covered with material in the width direction;

[0051] Step 2: The chain plate assembly 10 is started, driving the material laid in step 1 to move in the inner cavity of the feeding mechanism 2 toward the drying section;

[0052] Step 3: The dehumidification mechanism in the feeding mechanism 2 is started to initially dehumidify the material on the long wire, thereby reducing the moisture content of the material and shortening the drying time;

[0053] Step 4: The chain plate assembly 10 drives the material after the preliminary dehumidification in step 3 to enter the drying section. The number of dryers in the drying section is increased or decreased according to actual needs. The steam heat exchanger in the drying section is started to heat and dry the material on the long net. When the humidity in the drying section reaches the set value, the dehumidification fan 4 is started to discharge the condensed water (high temperature + liquid) with temperature in the drying section;

[0054] Step 5: At the same time, the waste heat recovery component 5 starts to work, the automatic air valve 13 opens, and the cold air from the outside starts to be replenished into the inner cavity of the drying section. The steam trap 18 between the dehumidification fan 4 and the water inlet pipe 16 opens, and the condensed water with temperature discharged from the steam heat exchanger in the drying section through the pipeline passes through the metal radiator 14, and heats the incoming cold air, so that the air replenished into the inner cavity of the drying section is hot air, realizing the utilization of waste heat;

[0055] Step 6: After drying is completed, the chain plate assembly 10 sends the material to the cooling mechanism 23 for cooling;

[0056] Step 7: The cooled material is transported to the unloading mechanism 6 driven by the chain plate assembly 10. The first crushing mechanism 7 in the unloading mechanism 6 first breaks up the material that has been cooled and bonded on the long net. The material after the first breaking falls to the unloading end of the cutting mechanism 6. In the process of falling, it is broken up again by the second crushing mechanism 8. The material that is broken up again is unloaded by the unloading spiral mechanism 12. After that, the material is dried.

[0057] Step 8: When unloading in step 7, the cleaning motor 24 in the cleaning scraper mechanism 9 is started, and the scraper 26 is attached to the long net in the chain plate assembly 10 to scrape off the debris or materials adhering to the surface of the long net, thereby ensuring the cleanliness of the surface of the long net. The cleaned long net runs to the feeding mechanism 2 to re-connect the material, and this cycle repeats.

[0058] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
