Description

Technical Field

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

[0002] The treatment and application of municipal waste biomass-based composite phase change materials have gradually attracted attention, among which the dehydration of biomass in municipal waste is one of the key treatment links. In the existing technology, biomass dehydration mainly adopts a single filter press or drying method, and there is a lack of equipment that effectively combines the two and optimizes the system.

[0003] The existing dehydration equipment specifically has the following problems: (1) When the roller filter press is used to filter and dehydrate biomass, the material tends to adhere to the filter belt. As the filter press process continues, this adhesion phenomenon gradually worsens, which not only affects the subsequent filtration effect of the filter belt on the material, resulting in reduced dehydration efficiency, but also requires frequent cleaning of the filter belt, increasing equipment maintenance costs and downtime; (2) During the drying process, materials will pile up, which will make it difficult for hot air to contact the materials evenly, resulting in poor drying effect. Some materials may not be fully dehydrated, which will extend the drying time and increase energy consumption. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a municipal garbage biomass-based composite phase change material dehydration device.

[0005] The technical solution is: a dehydration device for biomass-based composite phase change materials of urban garbage, including a bracket, on which a double-roll filter press is installed, the double-roll filter press includes two side plates, two pairs of drive rollers, two guide rollers, two filter belts with meshes and a connecting frame, two hollow brush cylinders driven by a gear set are rotatably connected between the two side plates, the hollow brush cylinders have bristles in contact with the filter belts, a drying box is installed on the bracket, a rotating spiral frame is provided in the drying box, a guide plate is connected inside the drying box, a fixed inclined plate is connected to the upper part of the guide plate, a movable inclined plate in contact with the fixed inclined plate is provided inside the drying box, and a moving mechanism for reciprocating the movable inclined plate is provided on the drying box.

[0008] 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.

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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] The present invention has the following advantages: 1.

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 DESCRIPTION

[0027] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article only refer to the positions of the structures shown in the corresponding drawings.

[0028] Example 1: Urban garbage biomass-based composite phase change material dehydration equipment, reference Figure 1-Figure 7, including a bracket 1, a roller filter press 2, a hollow brush cylinder 3, a drying box 4, a spiral frame 5, a guide plate 6, a fixed inclined plate 7, a movable inclined plate 8 and a moving mechanism. The roller filter press 2 is installed on the left side of the bracket 1. The roller filter press 2 includes two side plates 21, two pairs of driving rollers 22, two guide rollers 23, two filter belts 24 with meshes 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 rotatably connected to the two side plates 21. A driving motor for driving the driving rollers 22 to rotate is installed on the rear side plate 21 (Figure The filter press belt 24 is wound around a pair of driving rollers 22 and a guide roller 23, and the connecting frame 25 is located in the lower filter press belt 24. The water pressed out by the filter press belt 24 flows into the connecting frame 25 through the mesh for collection, and the collected water is discharged 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. The front and rear ends of the hollow brush cylinder 3 are fixedly connected with the small gear 31. The front and rear ends of the two driving rollers 22 on the right are fixedly connected with the large gear 32. The two small gears 31 are respectively connected to the two large gears. The gear 32 is meshed; the hollow brush cylinder 3 has bristles that contact the filter press belt 24. A drying box 4 is installed on the right side of the bracket 1. A heating box 41 for providing hot air is installed on the right side of the top of the drying box 4. The heating box 41 is a prior art. An inlet 42 is opened at the upper left end of the drying box 4, and a fan-shaped opening 43 is opened at the lower right end of the drying box 4. The bottom of the drying box 4 is inclined to allow the material to be discharged smoothly after drying and reduce material residue. In this embodiment, the inclination angle of the bottom of the drying box 4 is specifically 5 degrees; a rotating spiral frame 5 is provided on the lower side of the drying box 4, and a A rotating shaft 51 driven by a servo motor, a spiral frame 5 is fixedly connected to the rotating shaft 51, and a plurality of groups of levers 52 are connected to the rotating shaft 51 at intervals in the axial direction, each group having four levers 52; a guide plate 6 is fixedly connected to the left side of the drying box 4, a fixed inclined plate 7 is fixedly connected to the upper right side of the guide plate 6, a movable inclined plate 8 in contact with the fixed inclined plate 7 is provided inside the drying box 4, a moving mechanism for reciprocating the movable inclined plate 8 left and right is provided on the drying box 4, a slope 61 is provided on the right side of the guide plate 6, the slope 61 plays a guiding role for the material, and the material can fall onto the fixed inclined plate 7 through the slope 61.

[0029] refer to Figure 2 , Figure 5 , Figure 6 and Figure 7The 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. The baffle 81 is slidably connected to the left side of the drying box 4. The movable inclined plate 8 is fixedly connected to the middle part of the left side of the baffle 81. The front and rear sides of the baffle 81 are fixedly connected with connecting rods 82. The left ends of the connecting rods 82 are fixedly connected with left vertical rods 83. The middle part of the connecting rods 82 is provided with right vertical rods 84 that slide left and right. A spring 85 is fixedly connected between the right vertical rod 84 and the connecting rod 82. The front and rear ends of the transmission roller 22 at the lower right side are fixedly connected with cams 86. When the cam 86 rotates with the transmission roller 22, the cam 86 will intermittently squeeze the right vertical rod 84 and the left vertical rod 83 in turn to make the movable inclined plate 8 move back and forth left and right.

[0030] First, the crushed urban garbage biomass material is added into the double-roll filter press 2, and the driving motor is controlled to drive the transmission roller 22 to rotate, driving the two filter press belts 24 to rotate, the upper filter press belt 24 rotates counterclockwise, and the lower filter press belt 24 rotates clockwise. The two filter press belts 24 filter the material for preliminary dehydration, and the squeezed water enters the connecting frame 25 through the mesh of the filter press belt 24 for collection, so as to concentrate the water. The filtered material enters the drying box 4 through the inlet 42.

[0031] During the rotation of the driving roller 22, the two driving rollers 22 on the right side will drive the large gear 32 to rotate together, and the small gear 31 and the two hollow brush cylinders 3 will rotate under the meshing action. 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 cylinder 3 is higher than the rotation speed of the driving roller 22. The rotating hollow brush cylinder 3 can brush the material on the filter press belt 24 through the bristles, reduce the adhesion of the material on the filter press belt 24, and ensure the effect of the filter press belt 24 on the subsequent filtering of the material.

[0032] During the rotation of the transmission roller 22, the cam 86 will also rotate 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 squeeze 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 movable inclined plate 8 to move to the right together, the movable inclined plate 8 opens, and an opening is formed between the movable inclined plate 8 and the fixed inclined plate 7; the cam 86 continues to rotate, the cam 86 contacts the left vertical rod 83, and the rotating cam 86 squeezes 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 movable inclined plate 8 to move to the left together, and in this way, the rotating cam 86 can make the movable inclined plate 8 move back and forth left and right. Since the material after filtration is easy to be in sheet form, when the movable inclined plate 8 and the fixed inclined plate 7 are in contact and closed, the movable inclined plate 8 and the fixed inclined plate 7 will break the fallen material, reduce the stacking of the material, and improve the subsequent drying effect.

[0033] When the crushed material falls to the lower side of the drying box 4, the heating box 41 provides hot air and controls the servo motor to drive the rotating shaft 51 to rotate, thereby driving the spiral frame 5 and the lever 52 to rotate. The rotating spiral frame 5 and the lever 52 turn the material over, and the spiral frame 5 transports the material to the right, thereby drying and dehydrating the material in the drying box 4.

[0034] Example 2: Based on Example 1, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The urban garbage biomass-based composite phase change material dehydration equipment also includes a linear motor 91 and a moving rod 92. The linear motor 91 is connected to the top of the drying box 4, 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 limiting the moving stroke of the connecting rod 82.

[0035] When dehydrating materials of different sizes, it may be necessary to adjust the opening size when the movable inclined plate 8 and the fixed inclined plate 7 are separated. At this time, the linear motor 91 is controlled to drive the movable 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 movable inclined plate 8 to move to the right together, and the movable inclined plate 8 opens. When the connecting rod 82 contacts the movable rod 92, the connecting rod 82, the left vertical rod 83, the baffle 81 and the movable inclined plate 8 stop moving, and the cam 86 continues to squeeze the right vertical rod 84 to move to the right, and the spring 85 is compressed. In this way, the greater the distance the movable rod 92 moves to the left, the smaller the opening when the movable 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.

[0036] Embodiment 3: Based on Embodiment 2, refer to Figure 1 , Figure 2 and Figure 8 The urban garbage biomass-based composite phase change material dehydration equipment also includes a connecting pipe 10, and the front and rear sides of the heating box 41 and the ends of the two hollow brush cylinders 3 are connected with connecting pipes 10.

[0037] When the heating box 41 provides hot air, the hot air will also enter the two hollow brush cylinders 3 through the two connecting pipes 10, so that the temperature of the surface of the hollow brush cylinder 3 and the bristles increases. When the hollow brush cylinder 3 brushes the material on the filter press belt 24 off, the increased temperature can reduce the sticking of the material on the bristles, improve the cleaning effect, and thereby improve the overall dehydration efficiency.

[0038] Embodiment 4: Based on Embodiment 3, refer to Figure 1 , Figure 2 and Fig. 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.

[0039] 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.
