Description

Technical Field

[0001] This utility model relates to the technical field of soil remediation devices, and in particular to a device for remediating soil contaminated by solid waste. Background Technology

[0002] Direct discharge of solid waste such as industrial waste and domestic garbage can pollute the soil, potentially damaging soil structure, affecting ecosystems and human health. Once soil is contaminated, equipment is needed to remediate soil contaminated by solid waste. Treatment devices include screening and filtration to separate solid waste from soil, adding chemical reagents to neutralize or decompose pollutants, using microorganisms to degrade organic pollutants, and high-temperature incineration to decompose harmful substances.

[0003] In the treatment of soil and solid waste, the soil and solid waste are mixed together and need to be screened to separate the solid waste before soil purification. However, during the screening process, the soil particles are too large or some solid waste is covered by the soil, resulting in incomplete screening of soil and solid waste and affecting the separation effect of the contaminated soil treatment process. To address this problem, we propose a solid waste contaminated soil treatment device. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a device for treating soil contaminated by solid waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for treating soil contaminated by solid waste, comprising a base plate, a mounting frame, a mounting box, a motor, a material cylinder, and a mounting shaft. The base plate has a mounting frame at its upper end, and the mounting frame contains a mounting box with an inclined screen inside. Symmetrically distributed springs are arranged between the mounting boxes. A material cylinder is positioned above the base plate, and a bearing bracket is fixed above the material cylinder. A mounting shaft is rotatably mounted inside the bearing bracket. Multiple sets of cutting blades and striking rods arranged in a ring array are arranged on the outer wall of the mounting shaft. Multiple layers of annular guide plates are arranged on the inner wall of the material cylinder. A guide hopper is located at the lower end of the material cylinder, and a telescopic tube is located at the lower end of the guide hopper. A motor is fixed above the base plate, and a rotating shaft is located at the upper end of the motor.

[0006] Preferably, the outer wall of the mounting shaft is provided with equidistantly distributed rotating plates, and the lower end of the rotating plates is provided with scrapers that fit against the guide plate. The rotating plates rotate with the mounting shaft, driving the scrapers to push the solid material on the upper end of the guide plate, thus facilitating the flow of the solid material.

[0007] Preferably, the mounting bracket has symmetrically distributed sliding sleeves inside, and one end of the mounting frame has symmetrically distributed guide rods that are slidably installed inside the sliding sleeves. The design of the sliding sleeves and guide rods enhances the stability of the mounting frame and prevents the spring from shifting during operation.

[0008] Preferably, one end of the guide rod is provided with a mounting plate, and a ball bearing is rotatably mounted inside the mounting plate.

[0009] Preferably, the outer wall of the rotating shaft is provided with an impact plate, and a first ball is rotatably mounted inside the impact plate at the same horizontal height as the second ball. The impact plate drives the first ball to impact the second ball, and the adjustment of the rotation of the first and second balls reduces friction and resistance during passage.

[0010] Preferably, the upper end of the mounting frame is provided with a top cover communicating with the telescopic pipe, the lower end of the mounting frame is provided with a flow guide, and the lower end of the flow guide is provided with a discharge pipe. The design of the top cover and the flow guide effectively prevents material from splashing during processing, reducing environmental pollution.

[0011] Preferably, guide rails are provided on the inner walls of both the front and rear ends of the mounting bracket, and sliders are provided on both the front and rear ends of the mounting frame, which are slidably installed inside the guide rails. The mounting frame is guided by the sliders sliding inside the guide rails.

[0012] Preferably, the upper end of the screen is provided with equally spaced baffles, and one end of the mounting frame is provided with a discharge port. The baffles reduce the flow velocity of the flowing solids, prolonging the screening process of solid waste and soil, and the intercepted solids are discharged through the discharge port.

[0013] Preferably, a driven wheel is sleeved on the outer wall of the upper end of the mounting shaft, and a drive wheel is provided at the upper end of the rotating shaft. Both the driven wheel and the drive wheel are fitted with belts. When the rotating shaft rotates, the drive wheel drives the driven wheel to rotate through the belt linkage, thereby driving the mounting shaft to rotate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model involves sieving dried soil contaminated with solid waste through a screen. Before sieving, the mixture of solid waste and soil is fed into the material cylinder. A rotating cutting blade suddenly cuts the soil, and an impact rod amplifies the impact on the soil clumps, causing them to loosen suddenly and preventing the solid waste from being coated. After the solid waste and soil are separated, sieving is carried out, improving the soil sieving efficiency. The equipment can operate sustainably, improving the processing efficiency and the reproducibility of the soil. The separation effect is significantly improved when treating soil contaminated with solid waste. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, the present invention proposes a device for treating solid waste contaminated soil, comprising a base plate 1, a mounting frame 2, a mounting frame 4, a motor 7, a material cylinder 12, and a mounting shaft 23. The mounting frame 2 is provided on the upper end of the base plate 1, and the mounting frame 4 is provided inside the mounting frame 2. The mounting frame 4 is provided inside the mounting frame 4 and has an inclined screen 31. The material cylinder 12 is provided above the base plate 1, and a bearing bracket 13 is fixed above the material cylinder 12. The mounting shaft 23 is rotatably mounted inside the bearing bracket 13. The outer wall of the mounting shaft 23 is provided with multiple sets of cutting blades 14 and striking rods 16 arranged in a ring array. The inner wall of the material cylinder 12 is provided with multiple layers of ring-shaped guide plates 15. The lower end of the material cylinder 12 is provided with a guide bucket 11, and the lower end of the guide bucket 11 is provided with a telescopic tube 9. The motor 7 is fixed above the base plate 1, and a rotating shaft 10 is provided on the upper end of the motor 7.

[0024] The outer wall of the mounting shaft 23 is provided with rotating plates 18 that are evenly distributed, and the lower end of the rotating plates 18 is provided with scraper 17 that fits against the guide plate 15.

[0025] A driven wheel 21 is sleeved on the outer wall of the upper end of the mounting shaft 23, and a drive wheel 19 is provided on the upper end of the rotating shaft 10. Both the driven wheel 21 and the drive wheel 19 are sleeved with belts 20.

[0026] Based on the implementation steps of Embodiment 1: The motor 7 drives the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, the drive wheel 19 drives the driven wheel 21 to rotate through the linkage of the belt 20, which in turn drives the mounting shaft 23 to rotate. Because the size of the drive wheel 19 is larger than that of the driven wheel 21, the cutting blade 14 and the striking rod 16 rotate at high speed. The soil contaminated by solid waste is input into the material cylinder 12. Under the large-scale cutting, large pieces of solid matter are cut into small pieces. The striking rod 16 impacts the falling soil pieces. The falling solid waste and contaminated soil are received by the guide plate 15 and discharged downward through the central opening. The falling solid waste and contaminated soil are cut and struck multiple times, causing the falling solid waste and contaminated soil to loosen. During the screening process, the falling solid waste and contaminated soil are prevented from covering each other, which would prevent effective screening and lead to low soil utilization. The falling solid waste and contaminated soil are effectively separated by the screen 31.

[0027] like Figures 1-5 As shown, compared with Embodiment 1, the solid waste contaminated soil treatment device proposed in this utility model further includes: symmetrically distributed springs 6 between the mounting frame 4 and the mounting frame 2, symmetrically distributed sliding sleeves 26 inside the mounting frame 2, and symmetrically distributed guide rods 24 slidably installed inside the sliding sleeves 26 at one end of the mounting frame 4.

[0028] One end of the guide rod 24 is provided with a mounting plate 27, and a ball bearing 28 is rotatably mounted inside the mounting plate 27;

[0029] The outer wall of the rotating shaft 10 is provided with a striking plate 8, and inside the striking plate 8, a ball 22 is rotatably installed at the same horizontal height as the ball 28.

[0030] The upper end of the mounting frame 4 is provided with a top cover 3 that communicates with the telescopic pipe 9, the lower end of the mounting frame 4 is provided with a flow guide 33, and the lower end of the flow guide 33 is provided with a discharge pipe 5.

[0031] The mounting bracket 2 has guide rails 25 on the inner walls at both the front and rear ends, and the mounting frame 4 has sliders 29 that are slidably installed inside the guide rails 25 at both the front and rear ends.

[0032] The upper end of the screen 31 is provided with equally spaced baffles 32, and one end of the mounting frame 4 is provided with a discharge port 30;

[0033] In this embodiment, during the operation of the motor 7, the striking plate 8 is driven to rotate. When the first ball 22 rotates with the rotating shaft 10 and passes through the second ball 28, the second ball 28 is squeezed, which in turn drives the mounting plate 27 and the guide rod 24 to move, so that the spring 6 is compressed and stretched, which drives the mounting frame 4 to move. When the first ball 22 passes through the second ball 28, the spring 6 returns to its original position and vibrates, which drives the mounting frame 4 to vibrate. This allows solid waste and contaminated soil to be vibrated and screened during screening, improving screening efficiency. The intercepted solid waste is output through the discharge port 30, and the soil is guided through the guide hood 33 and output through the discharge pipe 5, realizing the separation of solid waste and soil. The telescopic pipe 9 provides stroke compensation for the mounting frame 4 during use, and the motor 7 drives the rotating shaft 10 and the mounting shaft 23 to rotate, reducing the use of electrical equipment and reducing energy consumption and operating costs.

[0034] The above specific embodiments are merely several preferred embodiments of this utility model.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
