Abstract
Description
Technical Field
[0001] This application relates to the field of adsorbent production technology, and more specifically, to a soil heavy metal adsorbent processing apparatus. Background Technology
[0002] For degraded soils, improving soil quality, mitigating soil acidification and salinization, preventing heavy metal pollution, reducing soil-borne diseases, and increasing crop yields are pressing issues that need to be addressed. The main method for restoring degraded soils is the use of soil conditioners.
[0003] Attapulgite clay is a hydrous magnesium-aluminate silicate clay mineral with a 2:1 structure. Its unique rod-shaped crystal structure effectively improves soil structure and alleviates soil compaction caused by poor water and fertilizer management. Attapulgite has a large specific surface area and abundant internal nanopores, which can buffer soil acidity and alkalinity, improve soil water and fertilizer retention, fix heavy metals in the soil, and adjust the soil microbial community structure.
[0004] Currently, in the production of functional fertilizers for soil remediation, the heavy metal remediation material is weighed and then manually fed into the mixer, resulting in a low level of automation. While weighing devices can be used to feed heavy metal remediation materials, the process requires control of various valves via a controller, making the structure and control complex and difficult to modify and manage. Furthermore, traditional PAL purification and processing methods often employ intermittent stirring, settling, and acid treatment processes. Typically, a motor drives a stirring rod to agitate the material in the tank. Since the position of the stirring rod is fixed, the material near the edge of the container is difficult to mix.
[0005] Therefore, a soil heavy metal adsorbent processing device is needed to solve the above problems. Utility Model Content
[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a soil heavy metal adsorbent processing device, comprising: a tank body, wherein sample tubes, observation windows, and discharge ports are provided on the periphery of the tank body; two sample tubes and two discharge ports are provided vertically; the observation windows are evenly distributed vertically and are embedded in the tank body, and are made of transparent material; the discharge port is fixedly provided at the upper end of the tank body; a fixed steel frame is installed on the cover; a metering mechanism and a motor are provided at the fixed steel frame; a driving rod is poweredly connected to the lower end of the motor; two evenly distributed driven rods are distributed on the outer periphery of the driving rod; threaded blades are provided on the outer periphery of the driven rods; the two threaded blades are parallel, non-meshing, and capable of rotating in opposite directions; a rotating mechanism is connected to the lower ends of the driving rod and the driven rods; a planetary gear is connected to the upper ends of the driving rod and the driven rods; a fixed ring is fixedly provided at the upper end of the tank body; a rotating disk is rotatably connected inside the fixed ring; and the planetary gear is disposed between the fixed ring and the rotating disk. Furthermore, the quantitative mechanism includes a fixed box, a telescopic mechanism, and a fixing mechanism. The telescopic mechanism includes a telescopic cylinder fixed to the fixed steel frame. One end of the telescopic cylinder has a telescopic rod fixedly connected to an insert plate. The insert plate is U-shaped, and a bottom cover and a top cover are fixedly distributed at the upper and lower ends of the insert plate. The top cover has an opening coaxially with the bottom cover. The fixing mechanism includes an extension box fixed inside the fixed box. Both the upper and lower ends of the extension box are connected to and fixedly connected to inlet and outlet cylinders. The upper and lower inlet and outlet cylinders are connected to the bottom cover and... The openings are coaxially arranged, and the bottom cover is located below the opening in a semi-circular shape. The other end of the bottom cover is rectangular. The bottom cover is flat and has a gap with the lower opening of the insert plate. The inlet and outlet cylinders at the lower end extend downward and are inserted into the lower end of the fixing ring. A left ring and a right ring are fixed in the extension box. The left ring has a sliding groove that slides and engages with the insert plate. The insert plate, the left ring, and the right ring form a circular cavity for quantitative material feeding. The length of the bottom cover is twice the diameter of the opening.
[0008] The beneficial effects of this application are as follows: 1. The slide plate is controlled to move within the extension box by a telescopic cylinder. The bottom cover, top cover and opening are set coaxially. During the left and right movement of the slide plate, the connection and closure of the upper and lower inlet and outlet cylinders are controlled respectively. With the insertion and cooperation of the slide plate and the sliding groove, a circular cavity is formed between the slide plate, the left ring and the right ring for storing materials and discharging materials in a quantitative manner. The amount of discharged materials is controllable, and the upper inlet and outlet cylinders can prevent material overflow. It is convenient to control the conveying and addition of materials. The structure and control are relatively simple and easy to modify and implement.
[0009] 2. By rotating in the same direction with two driven rods, the light phase PAL fibers are continuously pushed upwards, causing the heavy phase impurity particles to move downwards. The revolution of the driven rods ensures that their working range covers the entire tank, eliminating the flow and mixing dead zones that may exist in traditional fixed-shaft screws. Through the centrifugal process of the revolution itself, the densest impurity particles are subjected to the strongest centrifugal force, accelerating their downward fall and improving production efficiency.

A rotating mechanism 20 is connected between the lower ends of the two driven rods 19 and the rotating seat at the drive rod 18. The rotating mechanism 20 is integrally formed and rotatably connected to the rotating seat. A fixed... A fixed ring 21 is rotatably connected to a rotating disk 22. A planetary gear 23 is provided between the cover 14 and the rotating disk 22. The planetary gear 23 is connected to the driving rod 18 and two driven rods 19 respectively. The planetary gear 23 includes a gear ring, planetary gears and a driving gear. The planetary gears are fixedly connected to the driven rods 19, the driving gears are fixedly connected to the driving rod 18, and the gear ring is fixedly connected to the cover 14. The driving rod 18, which is powered by the motor 17, is rotated by the control motor 17. Under the connection between the driving rod 18 and the planetary gear 23... The planetary gear 23 drives the two driven rods 19 connected to the side of the driving rod 18 to rotate synchronously and in the same direction and revolve around the driving rod 18. The driven rods 19 remain stable under the rotational connection with the rotating mechanism 20 and the rotational connection between the fixed ring 21 and the rotating disk 22. The material is quantitatively added by the quantitative mechanism 16. The staff extracts and tests the sample by opening the connection between the sample tube 11 and the sampling mechanism. Finally, the impurities and adsorbent material are discharged through the discharge port 13. The liquid level stratification in the tank 10 is observed through the observation window 12.
[0022] Reference Figure 5-9The quantitative mechanism 16 includes a fixed box 30, a telescopic mechanism 31, and a fixing mechanism 32. The fixed box 30 consists of a rectangular frame with openings on both sides. Two connecting rods are fixed at the upper end of the rectangular frame and abut against a fixed steel frame 15. The connecting rods and the fixed steel frame 15 are connected by threaded parts. The telescopic mechanism 31 includes a telescopic cylinder 40 fixed on the fixed steel frame 15. One end of the telescopic cylinder 40 is provided with a telescopic rod and a fixed insert plate 41. The insert plate 41 is U-shaped, with the left ring 53 and the right ring 54 being semi-circular.

Specifically, the telescopic cylinder 40 moves the telescopic rod outwards, pushing the insert plate 41, which is fixedly connected to the telescopic rod, to move (towards...). Figure 9 (The orientation moves to the right), thereby causing the opening 44 to disengage from the connection with the inlet and outlet cylinder 50. At this time, the top cover 43 blocks the material in the upper inlet and outlet cylinder 50 from moving downward, while the bottom cover 42 maintains a closed relationship with the inlet and outlet cylinder 50. As the telescopic cylinder 40 continues to work, the bottom cover 42 continues to move to the right, and then the bottom cover 42 loses its obstruction to the lower inlet and outlet cylinder 50. The material below the top cover 43 is discharged downward through the inlet and outlet cylinder 50 through the lower opening of the insert plate 41.
