Description

Technical Field

[0001] This utility model relates to the field of solid waste detection technology, and more specifically, to a solid waste detection sieve structure. Background Technology

[0002] Solid waste testing refers to the determination and evaluation of the physical, chemical, and biological characteristics of solid waste through a series of analytical methods and techniques. Testing can provide a scientific basis for the classification, collection, transportation, treatment, and disposal of solid waste, enabling the formulation of reasonable environmental protection policies and measures to prevent solid waste from polluting the environment. It also helps to achieve the reduction, resource utilization, and harmless treatment of solid waste. In the process of solid waste testing, solid waste needs to be screened and filtered.

[0003] A search revealed that Chinese Patent CN219232703U discloses a filtration mechanism for a solid waste testing device. This mechanism uses protrusions to restrict the filter barrel. After the motor starts, it drives a rotating shaft via a bevel gear set, causing the rotating disc to rotate the filter barrel, thus filtering the aqueous solution from the moist solid waste. By testing the aqueous solution and the drained solid waste separately, the accuracy of the solid waste testing results can be ensured. Furthermore, the bottom of the filter barrel has a groove that matches the protrusions, facilitating the use of filter barrels of different sizes and increasing the device's practicality.

[0004] When the above-mentioned patent is used, solid waste can be filtered through the filter bucket, but it is inconvenient to separate solid waste according to different particle sizes. Solid waste with different particle sizes will contain different components and pollutants. Separating them by particle size before testing can more accurately analyze the composition and characteristics of solid waste; if they are not separated, the test results will not be accurate enough.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a solid waste detection screening structure, including a storage cylinder, a conveying pipe, and a separation box, wherein the top and bottom ends of the conveying pipe are fixedly connected to the storage cylinder and the separation box, respectively; a cylinder cover is fixedly connected to the top end of the storage cylinder by bolts; a feed hopper is fixedly connected to the top end of the cylinder cover; a perforated plate is fixedly connected inside the separation box; an adjustment component is provided at the bottom of the perforated plate; the adjustment component includes a second stepper motor, a lead screw, multiple sliders, a sliding rod, and multiple partitions; the second stepper motor is fixedly installed on one side of the separation box, and the output shaft end of the second stepper motor is fixedly connected to the lead screw; both ends of the lead screw are movably connected to the separation box through bearings; both ends of the sliding rod are fixedly connected to the separation box; multiple sliders are movably sleeved on the lead screw and the sliding rod, and one side of each slider is fixedly connected to multiple partitions.

[0007] Furthermore, an inclined plate is movably provided at the bottom of the lead screw, and the inclined plate is fixedly installed inside the separation box. A discharge hopper is movably provided on one side of the inclined plate, and one side of the discharge hopper is fixedly connected to the separation box.

[0008] As can be seen, in the above technical solution, the inclined plate guides the screened solid waste, and finally discharges the solid waste through the discharge hopper.

[0009] Furthermore, a vibrator is fixedly connected to the bottom of the separation box, and a base plate is fixedly connected to the bottom of the vibrator.

[0010] It can be seen that the above technical solutions aim to accelerate the screening speed of solid waste.

[0011] Furthermore, telescopic rods are fixedly connected to the top of the base plate near the four corners, and the tops of the multiple telescopic rods are fixedly connected to the separation box.

[0012] It can be seen that the above technical solution is designed to facilitate the support of the separation box.

[0013] Furthermore, a heater is movably installed on one side of the conveying pipe, and the heater is fixedly installed at the bottom end of the storage cylinder.

[0014] It can be seen that the above technical solution is designed to facilitate the drying of solid waste in the storage cylinder.

[0015] Furthermore, a baffle is movably installed inside the conveying pipe. A hydraulic cylinder is fixedly connected to one side of the baffle, and a vertical plate is fixedly connected to the other side of the hydraulic cylinder. The bottom end of the vertical plate is fixedly connected to the separation box.

[0016] As can be seen, in the above technical solution, when the hydraulic cylinder is activated, the piston rod on the hydraulic cylinder retracts, causing the baffle to move away from the conveying pipe, and the solid waste in the storage cylinder can enter the separation box through the conveying pipe.

[0017] Furthermore, a first stepper motor is fixedly installed at the center of the top of the cylinder cover, and a stirring rod is fixedly connected to the end of the output shaft of the first stepper motor, with the stirring rod located inside the storage cylinder.

[0018] It can be seen that the above technical solutions are designed to ensure that solid waste can be fully heated.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. This utility model uses a perforated plate to screen solid waste. The second stepper motor drives the lead screw to rotate, which can drive multiple partitions to move horizontally. The size of the mesh holes on the perforated plate can be adjusted according to the needs, so that solid waste of different particle sizes can be screened. The operation is simple and convenient for screening solid waste. The vibrator drives the separation box to vibrate, which can accelerate the screening speed of solid waste.

[0021] 2. This utility model guides solid waste through a feeding hopper.

The first step motor drives the stirring rod to rotate, which stirs the solid waste in the storage cylinder and ensures that the solid waste is fully heated. The structure is simple and facilitates the drying of solid waste. Attached Figure Description
