Description

Technical Field

[0001] This utility model belongs to the field of wet waste recycling and processing technology, specifically relating to a wet waste conveying system. Background Technology

[0002] Due to environmental protection and land use needs, it is necessary to relocate and rehabilitate landfills with inadequate anti-seepage systems. This involves removing the landfilled waste, sorting it, and then classifying it for utilization and disposal, thereby achieving land recovery, resource utilization, and environmental protection. The typical process for this relocation and rehabilitation is as follows: constructing a drying and sorting area near the landfill; excavating the landfill waste; transporting it by vehicle to the drying area; mechanically turning and mixing the waste in the drying area to reduce its moisture content; transporting the waste with low moisture content to the sorting site and piling it near the inlet of the sorting equipment; feeding and sorting the waste; and finally, transporting the sorted waste off-site for classified utilization.

[0003] The existing off-site relocation and treatment methods have the following drawbacks: 1) The process is cumbersome, involving two short-haul loading and unloading operations and one material feeding operation (excavator loading and unloading at the sorting equipment inlet); 2) The cycle is long, involving the construction of cement hardening of the drying area to prevent leachate from seeping into the soil below and causing pollution; 3) The drying cycle is long because the existing waste screening equipment has high requirements for the moisture content of the feed material, usually requiring a moisture content of less than 30%, otherwise different types of waste will stick together and become unsuitable for sorting. However, the excavated waste often has a moisture content of 50%-80%, so the moisture content of the waste must be reduced before screening; and the moisture content of the waste... The rate of waste drying is usually reduced by 3-7 sunny days and the construction period is delayed due to rainy days when drying is not possible; 4) It occupies a large area, and the landfills that need to be cleaned are often plots with high land use value. It is difficult to find a large enough open space nearby to build a drying area. If the drying area is not large enough, the amount of waste dried will be small, which will slow down the downstream screening and delay the entire operation cycle; 5) It poses a high environmental risk. The odor from open-air drying will overflow and affect the lives and health of nearby residents; 6) It is highly dependent on the weather. If the waste is not covered in time on rainy days, rainwater will seep into the waste and leachate will spread and overflow, polluting the soil and groundwater.

[0004] Therefore, it is essential to design a wet waste conveying device to transport the wet waste that needs to be moved to another location to the waste sorting equipment. Utility Model Content

[0005] To address the above problems, this utility model provides a wet waste conveying system.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a wet waste conveying system, comprising several sets of conveying components, each set of conveying components including a conveyor belt and a support device disposed below the conveyor belt; wherein, the conveyor belt is inclined upward along its conveying direction, the inclination angle of the conveyor belt is 30 to 75°, and several drainage holes are evenly distributed on the conveyor belt.

[0007] The support device includes a support plate and at least one pair of retractable support rods detachably disposed between the conveyor belt and the support plate. The top surface of the support plate is inclined downward along the conveying direction of the conveyor belt. The width of the top surface of the support plate is greater than the width of the conveyor belt. A baffle is also provided on the outer edge of the top surface of the support plate. A guide port is provided at the lower end of the top surface of the support plate.

[0008] Each set of conveying components is arranged in sequence, with the starting end of the conveyor belt of the latter set of two adjacent sets of conveying components positioned below the end of the conveyor belt of the former set of conveying components, so as to receive the wet waste falling from the conveyor belt of the former set of conveying components.

[0009] The wet waste conveying system of this utility model involves multiple lifting and gravity-induced descent of the wet waste during the conveying process, which promotes the dispersion of sticky waste and accelerates the drying of the wet waste. The leachate on the conveyor belt falls through the drainage holes onto the support plate and is discharged through the guide port of the support plate.

[0010] It should be noted that the tilt angle of the conveyor belt is the angle between the conveyor belt and the horizontal plane.

[0011] The present invention is further configured such that the inclination angle of the top surface of the support plate is 15-45°. The inclination angle of the top surface of the support plate is the angle between the conveyor belt and the horizontal plane. This configuration allows the seepage falling on the support plate to slide down along the inclination direction of the support plate to the guide port and be discharged through the guide port.

[0012] The present invention is further configured such that a T-shaped groove is formed on the top surface of the support plate along its length, and a T-shaped slider matching the T-shaped groove is provided at the bottom end of the support rod. This configuration allows the position of the conveyor belt on the support plate to be adjusted by sliding the support rod along the T-shaped groove.

[0013] The present invention is further configured such that a canopy is provided above the conveyor belt, and the bottom ends of both sides of the canopy are mounted on the support plate.

[0014] The present invention is further configured such that the canopy is an arched canopy, with the bottom ends of both sides of the arched canopy resting on the support plate. The arched canopy provides shelter above the conveyor belt and the support device.

[0015] The present invention is further configured such that the wet waste conveying system also includes a hot air device, which is used to deliver hot air into the arched shed to accelerate the drying of the wet waste.

[0016] The present invention is further provided that a temperature and humidity sensor is also provided inside the arched shed.

[0017] The present invention is further configured such that the wet waste conveying system also includes a leachate collection device for collecting the leachate discharged from the diversion port.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The wet waste conveying system provided by this utility model directly transports the waste from the waste excavation area to the screening equipment, avoiding the multiple short-haul loading and unloading and the construction of the drying area in the prior art. In addition, the waste is dispersed and the moisture content of the wet waste is reduced by multiple gravity drops during the wet waste conveying process, and the process is also simpler.

[0020] (2) The wet waste conveying system provided by this utility model can arrange the conveying components according to the specific site, which is highly flexible and easy to transport. Attached Figure Description

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides a wet waste conveying system, including several sets of conveying components. Each set of conveying components includes a conveyor belt 1 and a support device disposed below the conveyor belt 1; wherein,

[0028] The conveyor belt 1 is inclined upward along its conveying direction, with an inclination angle of 30 to 75°. Several drainage holes (not shown in the figure) are evenly distributed on the conveyor belt 1 to filter out moisture from the wet waste.

[0029] The support device includes a support plate 2 and at least one pair of retractable support rods 3 detachably disposed between the conveyor belt 1 and the support plate 2; the top surface of the support plate 2 is inclined downward along the conveying direction of the conveyor belt 1, and the width of the top surface of the support plate 2 is greater than the width of the conveyor belt 1; a baffle 4 is provided along the outer edge of the top surface of the support plate 2, and a guide port 5 is provided at the lower end of the top surface of the support plate 2.

[0030] Each set of conveying components is arranged in sequence. The starting end of the conveyor belt 1 of the latter set of two adjacent sets of conveying components is placed below the end of the conveyor belt of the former set of conveying components to receive the wet waste falling from the conveyor belt of the former set of conveying components.

[0031] The wet waste conveying system described in this embodiment directly transports waste from the excavation area to the inlet of the screening equipment. First, the conveying components are connected in series. The first set of conveying components is located in the excavation area, and the last set is located at the screening equipment. The wet waste to be transferred is transported by the previous conveyor belt, then falls by gravity to the next conveyor belt, and finally is directly conveyed to the inlet of the screening equipment. During transportation, the wet waste undergoes multiple lifting and gravity-induced descent, promoting the dispersion of adhering waste and accelerating its drying. Leakage on the conveyor belt falls through drainage holes onto the support plate and is discharged through the guide port 5 on the support plate.

[0032] Example 2

[0033] Such as 2 and Figure 3 As shown, compared to Embodiment 1, this embodiment differs in that: a canopy 6 is provided above the conveyor belt, and the canopy 6 is an arched canopy. The bottom ends of both sides of the canopy 6 are detachably connected to the support plate 2. This arrangement provides shelter above the conveyor assembly. Furthermore, a T-shaped groove 7 is formed on the top surface of the support plate 2 along its length, and the bottom end of the support rod 3 is provided with a T-shaped slider that matches the T-shaped groove 7. The support rod 3 and the T-shaped groove 7 are slidably connected. This arrangement allows for adjustment of the position of the conveyor belt 1 by moving the support rod 3.

[0034] Example 3

[0035] Compared with Example 2, the difference in this example is that a hot air device and a temperature and humidity sensor are also provided. The hot air device is used to deliver hot air to the upper part of the arched shed, thereby accelerating the drying of wet waste; the temperature and humidity sensor is located inside the shed 6 to detect the temperature and humidity inside the shed.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
