Description

Technical Field

[0001] The present invention belongs to the technical field of material dehydration, and particularly relates to a dehydration device for urban waste biomass-based composite phase change materials. Background Art

[0002] The treatment and application of urban waste biomass-based composite phase change materials have gradually attracted attention, among which the dehydration of biomass in urban waste is one of the key treatment links. In the prior art, the dehydration of biomass mainly adopts a single pressure filtration or drying method, lacking equipment that effectively combines the two and optimizes the system.

[0003] The existing dehydration equipment specifically has the following problems:

[0004] (1) When the roller pressure filter presses and dehydrates biomass, the material is easily adhered to the pressure filter belt. As the pressure filtration process continues, this adhesion phenomenon gradually worsens, not only affecting the subsequent pressure filtration effect of the pressure filter belt on the material, resulting in a decrease in dehydration efficiency, but also requiring frequent cleaning of the pressure filter belt, increasing the maintenance cost and downtime of the equipment;

[0005] (2) During the drying process, the material will stack up. The stacking of the material makes it difficult for the hot air to contact the material evenly, resulting in poor drying effect. Some materials may not be fully dehydrated, prolonging the drying time and increasing energy consumption. Summary of the Invention

[0006] In order to solve the problems raised in the above background art, the present invention provides a dehydration device for urban waste biomass-based composite phase change materials.

[0007] The technical solution is as follows: A dehydration device for urban waste biomass-based composite phase change materials, including a bracket, on which a roller pressure filter is installed. The roller pressure filter includes two side plates, two pairs of driving rollers, two guide rollers, two pressure filter belts with mesh holes, and a connecting frame. Between the two side plates, two hollow brush cylinders driven by a gear set are rotatably connected. The hollow brush cylinders have bristles in contact with the pressure filter belts. A drying box is installed on the bracket. Inside the drying box, a rotating spiral rack is provided. Inside the drying box, a guide plate is connected. The upper part of the guide plate is connected with a fixed inclined plate. Inside the drying box, a moving inclined plate in contact with the fixed inclined plate is provided. A moving mechanism for reciprocating the moving inclined plate is provided on the drying box.

[0008] As a further preferred solution, the gear set includes a small gear and a large gear. Small gears are connected to both ends of the hollow brush cylinders. Large gears are connected to both ends of the two driving rollers close to the drying box. The two small gears are respectively meshed with the two large gears.

[0009] As a further preferred solution, a heating box is installed on the top of the drying box, an entrance is opened at the left end of the drying box, a fan-shaped opening is opened at the right end of the drying box, the bottom of the drying box is inclined, and the guide plate has an inclined surface.

[0010] As a further preferred solution, a rotating shaft driven by a servo motor is installed in the drying box, the spiral frame is connected to the rotating shaft, and the rotating shaft is connected to multiple groups of levers at intervals in the axial direction.

[0011] As a further preferred scheme, the moving mechanism includes a baffle, a connecting rod, a left vertical rod, a right vertical rod, a spring and a cam. The baffle is slidably connected inside the drying box, the movable inclined plate is connected to the middle of the baffle, two connecting rods are connected to the baffle, the left ends of the connecting rods are connected to the left vertical rod, the middle of the connecting rods is provided with a sliding right vertical rod, a spring is connected between the right vertical rod and the connecting rod, and cams are connected to both ends of the transmission roller at the lower right side. When the cam rotates with the transmission roller, the cam will intermittently squeeze the right vertical rod and the left vertical rod in turn to make the movable inclined plate move back and forth left and right.

[0012] As a further preferred solution, the urban waste biomass-based composite phase change material dehydration equipment also includes a linear motor and a moving rod. The drying box is connected to the linear motor, and the moving rod is installed on the linear motor. The moving rod is used to block the connecting rod, thereby limiting the moving stroke of the connecting rod.

[0013] As a further preferred solution, the urban garbage biomass-based composite phase change material dehydration equipment also includes a connecting pipe, and the heating box and the two hollow brush cylinders are connected by a connecting pipe.

[0014] As a further preferred embodiment, the urban garbage biomass-based composite phase change material dehydration equipment also includes a discharge frame, a connecting shaft, a rotating plate and an opening and closing plate. The lower part of the drying box is connected to a discharge frame covering the fan-shaped opening 1. The inside of the discharge frame is rotatably connected to a connecting shaft connected to the rotating shaft. The connecting shaft is connected to a rotating plate. The rotating plate is provided with a fan-shaped opening 2. The bottom of the discharge frame is provided with a discharge opening. An opening and closing plate driven by an electric push rod is installed at the bottom of the discharge frame. The opening and closing plate has the states of blocking the discharge opening and not blocking the discharge opening. When the rotating plate rotates, the fan-shaped opening 2 is aligned with or staggered from the fan-shaped opening 1.

[0015] The present invention has the following advantages: 1. After being filtered by the roller filter press, the material enters the drying box for drying, and the rotating spiral frame and the lever turn the material over. Under the action of the gear set, the rotating hollow brush cylinder brushes the material off the filter belt through the bristles, thereby reducing material adhesion and ensuring the effect of subsequent filtering of the material by the filter belt. The moving inclined plate is reciprocated by the moving mechanism to break the material, thereby reducing material stacking and improving the drying effect.

[0016] 2. Control the linear motor to drive the moving rod to move left. The moving rod limits the moving stroke of the connecting rod. The greater the distance the moving rod moves to the left, the smaller the opening when the moving inclined plate and the fixed inclined plate are separated. Therefore, the opening size can be adjusted according to actual needs, with higher adaptability.

[0017] 3. The hot air provided by the heating box enters the two hollow brush cylinders through the connecting pipe, which increases the temperature of the surface of the hollow brush cylinder and the bristles, reduces the sticking of materials on the bristles, improves the cleaning effect, and thus improves the overall dehydration efficiency.

[0018] 4. The rotating shaft drives the connecting shaft and the rotating plate to rotate, and the fan-shaped opening 2 and the fan-shaped opening 1 are intermittently staggered and aligned. When the fan-shaped opening 2 and the fan-shaped opening 1 are aligned, the opening and closing plate is closed, and the dried material enters the discharge frame. When the fan-shaped opening 2 and the fan-shaped opening 1 are staggered, the opening and closing plate is opened, so that the dried material is discharged intermittently, reducing heat loss and improving the drying effect.

Detailed implementation mode

[0029] The following further illustrates the technical solution in combination with specific embodiments. It should be noted that: the words indicating directions such as up, down, left, and right mentioned in this article are only in terms of the positions of the shown structures in the corresponding drawings.

[0030] Example 1: Dehydration equipment for urban waste biomass-based composite phase change materials, refer to Figures 1-7, including a bracket 1, a pair-roll filter press 2, a hollow brush cylinder 3, a drying oven 4, a spiral rack 5, a guide plate 6, a fixed inclined plate 7, a movable inclined plate 8 and a moving mechanism. A pair-roll filter press 2 is installed on the left side of the bracket 1. The pair-roll filter press 2 includes two side plates 21, two pairs of driving rollers 22, two guide rollers 23, two filter belts 24 with mesh holes and a connecting frame 25 with a drain port. The two side plates 21 are connected to the left part of the bracket 1. The driving rollers 22 and the guide rollers 23 are both rotatably connected to the two side plates 21. A driving motor (not shown in the figure) for driving the driving rollers 22 to rotate is installed on the rear side plate 21. The filter belts 24 are wound around a pair of driving rollers 22 and a guide roller 23. The connecting frame 25 is located inside the lower filter belt 24. The water pressed out from the filter belts 24 flows into the connecting frame 25 through the mesh holes for collection, and the collected water is discharged centrally through the drain port. Two hollow brush cylinders 3 driven by a gear set are rotatably connected between the two side plates 21. The gear set includes a small gear 31 and a large gear 32. Small gears 31 are fixedly connected to both the front and rear ends of the hollow brush cylinder 3. Large gears 32 are fixedly connected to both the front and rear ends of the two driving rollers 22 on the right side. The two small gears 31 are respectively meshed with the two large gears 32. The hollow brush cylinder 3 has bristles that contact the filter belts 24. A drying oven 4 is installed on the right side of the bracket 1. A heating box 41 for providing hot air is installed on the upper right side of the top of the drying oven 4. The heating box 41 is a prior art. An inlet 42 is opened in the upper left part of the drying oven 4, and a sector-shaped opening 43 is opened in the lower right part of the drying oven 4. The bottom inside the drying oven 4 is inclined to enable the dried material to be discharged smoothly and reduce material residue. In this embodiment, the inclination angle of the bottom inside the drying oven 4 is specifically 5 degrees. A rotating spiral rack 5 is provided on the lower side inside the drying oven 4. A rotating shaft 51 driven by a servo motor is installed on the lower side inside the drying oven 4. The spiral rack 5 is fixedly connected to the rotating shaft 51. The rotating shaft 51 is axially spaced and connected with multiple groups of stirring rods 52, and each group has four stirring rods 52. A guide plate 6 is fixedly connected to the left side inside the drying oven 4. A fixed inclined plate 7 is fixedly connected to the upper right side of the guide plate 6. A movable inclined plate 8 that contacts the fixed inclined plate 7 is provided inside the drying oven 4. A moving mechanism for moving the movable inclined plate 8 left and right is provided on the drying oven 4. The right side of the guide plate 6 has an inclined surface 61, and the inclined surface 61 guides the material, enabling the material to fall onto the fixed inclined plate 7 smoothly along the inclined surface 61.

[0031] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7, the moving mechanism includes a baffle 81, a connecting rod 82, a left vertical rod 83, a right vertical rod 84, a spring 85 and a cam 86. A baffle 81 is slidably connected to the left side inside the drying box 4. A moving inclined plate 8 is fixedly connected to the middle of the left side of the baffle 81. Connecting rods 82 are fixedly connected to both the front and rear sides of the baffle 81. Left vertical rods 83 are fixedly connected to the left ends of the connecting rods 82. Right vertical rods 84 that slide left and right are provided in the middle of the connecting rods 82. A spring 85 is fixedly connected between the right vertical rod 84 and the connecting rod 82. Cams 86 are fixedly connected to both the front and rear ends of the lower right transmission roller 22. When the cam 86 rotates together with the transmission roller 22, the cam 86 will intermittently press the right vertical rod 84 and the left vertical rod 83 in sequence, so that the moving inclined plate 8 moves left and right reciprocally.

[0032] First, add the crushed urban waste biomass material into the double-roll filter press 2, control the driving motor to drive the transmission roller 22 to rotate, drive the two filter belts 24 to rotate. The rotation direction of the upper filter belt 24 is counterclockwise, and the rotation direction of the lower filter belt 24 is clockwise. The two filter belts 24 perform pressure filtration on the material for preliminary dehydration. The pressed-out water enters the connecting frame 25 through the mesh holes of the filter belt 24 for collection, so as to centrally discharge the water. The filtered material enters the drying box 4 through the inlet 42.

[0033] During the rotation of the transmission roller 22, the two transmission rollers 22 on the right side will drive the large gear 32 to rotate together. Under the meshing action, the small gear 31 and the two hollow brush barrels 3 rotate. Since the number of teeth of the large gear 32 is greater than the number of teeth of the small gear 31, the rotation speed of the hollow brush barrel 3 is higher than the rotation speed of the transmission roller 22. The rotating hollow brush barrel 3 can brush off the material on the filter belt 24 through the bristles, reduce the adhesion of the material on the filter belt 24, and ensure the subsequent pressure filtration effect of the filter belt 24 on the material.

[0034] During the rotation of the transmission roller 22, the cam 86 will also rotate together with the two transmission rollers 22 on the right side. When the cam 86 contacts the right vertical rod 84, the rotating cam 86 will press the right vertical rod 84 to move to the right, driving the connecting rod 82, the left vertical rod 83, the baffle 81 and the moving inclined plate 8 to move to the right together. The moving inclined plate 8 opens, and an opening is formed between the moving inclined plate 8 and the fixed inclined plate 7. The cam 86 continues to rotate. The cam 86 contacts the left vertical rod 83. The rotating cam 86 presses the left vertical rod 83 to move to the left, driving the connecting rod 82, the right vertical rod 84, the baffle 81 and the moving inclined plate 8 to move to the left together. In this way, the rotating cam 86 can make the moving inclined plate 8 move left and right reciprocally. Since the filtered material is easy to be in the shape of flakes, when the moving inclined plate 8 and the fixed inclined plate 7 contact and close, the moving inclined plate 8 and the fixed inclined plate 7 break the falling material, reduce the stacking of the material, and improve the subsequent drying effect.

[0035] After the crushed material falls to the lower side inside the drying box 4, the heating box 41 provides hot air, and controls the servo motor to drive the rotating shaft 51 to rotate, driving the spiral rack 5 and the lever 52 to rotate. The material is turned by the rotating spiral rack 5 and the lever 52, and at the same time the spiral rack 5 conveys the material to the right, so as to dry and dehydrate the material in the drying box 4.

[0036] Example 2: On the basis of Example 1, referring to Figure 1 , Figure 2 , Figure 5 and Figure 6 , the urban waste biomass-based composite phase change material dehydration device further includes a linear motor 91 and a moving rod 92. The top of the drying box 4 is connected to the linear motor 91, and the moving rod 92 is installed on the linear motor 91. The moving rod 92 is used to block the connecting rod 82, thereby restricting the moving stroke of the connecting rod 82.

[0037] When dehydrating materials of different sizes, it may be necessary to adjust the opening size when the moving inclined plate 8 and the fixed inclined plate 7 are separated. At this time, control the linear motor 91 to drive the moving rod 92 to move to the left. When the rotating cam 86 squeezes the right vertical rod 84 to move to the right, it drives the connecting rod 82, the left vertical rod 83, the baffle 81 and the moving inclined plate 8 to move to the right together. The moving inclined plate 8 opens. When the connecting rod 82 contacts the moving rod 92, the connecting rod 82, the left vertical rod 83, the baffle 81 and the moving inclined plate 8 stop moving, while the cam 86 continues to squeeze the right vertical rod 84 to move to the right, and the spring 85 compresses. In this way, the greater the distance the moving rod 92 moves to the left, the smaller the opening when the moving inclined plate 8 and the fixed inclined plate 7 are separated, so that the opening size can be adjusted according to actual needs, and the adaptability is higher.

[0038] Example 3: On the basis of Example 2, referring to Figure 1 , Figure 2 and Figure 8 , the urban waste biomass-based composite phase change material dehydration device further includes a communicating pipe 10. The front and back sides of the heating box 41 are both communicated with the ends of two hollow brush barrels 3 through the communicating pipe 10.

[0039] When the heating box 41 provides hot air, the hot air will also enter the two hollow brush barrels 3 through the two communicating pipes 10, so that the temperature of the surface of the hollow brush barrels 3 and the bristles increases. When the hollow brush barrels 3 brush the material on the filter press belt 24, the increased temperature can reduce the adhesion of the material on the bristles, improve the cleaning effect, and thus improve the overall dehydration efficiency.

[0040] Example 4: On the basis of Example 3, referring to Figure 1 , Figure 2 and Figure 9The urban garbage biomass-based composite phase change material dehydration equipment also includes a discharging frame 111, a connecting shaft 112, a rotating plate 113 and an opening and closing plate 115. The lower right side of the drying box 4 is fixedly connected to the discharging frame 111 covering the fan-shaped opening 43, and the discharging frame 111 is rotatably connected with the connecting shaft 112 inside. The left end of the connecting shaft 112 is fixedly connected to the right end of the rotating shaft 51, and the left part of the connecting shaft 112 is fixedly connected to the rotating plate 113. The rotating plate 113 is provided with a fan-shaped opening 114. The discharging opening is provided on the right side of the bottom of the discharging frame 111. An opening and closing plate 115 driven by an electric push rod is installed at the bottom of the discharging frame 111. The electric push rod is installed at the bottom of the discharging frame 111. The opening and closing plate 115 has the state of blocking the discharging opening and not blocking the discharging opening; when the rotating plate 113 rotates, the fan-shaped opening 114 is aligned with or staggered from the fan-shaped opening 43.

[0041] During the rotation of the rotating shaft 51, the connecting shaft 112 and the rotating plate 113 will rotate with the rotating shaft 51. When the rotating plate 113 rotates, the fan-shaped opening 114 and the fan-shaped opening 1 43 will be intermittently staggered and aligned. When the fan-shaped opening 114 and the fan-shaped opening 1 43 are aligned, the opening and closing plate 115 is closed, and the dried material enters the discharge frame 111 through the fan-shaped opening 114 and the fan-shaped opening 1 43. When the fan-shaped opening 114 and the fan-shaped opening 1 43 are staggered, the electric push rod is controlled to drive the opening and closing plate 115 to move and open, and the material in the discharge frame 111 is discharged through the discharge port. In this way, the dried material can be discharged intermittently, heat loss can be reduced, and the temperature stability in the drying box 4 can be improved, thereby improving the drying effect.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
