Description

Technical Field

[0001] This utility model relates to the field of impurity removal technology for granular soil raw materials, and in particular to a granular soil raw material impurity removal device for water conservancy projects. Background Technology

[0002] Granular soil raw materials, such as sand, gravel, and clay, are core materials for water conservancy projects, dikes, dams, and geomembrane laying. Their purity directly affects the stability, durability, and environmental compliance of the engineering structure. Granular soil raw material impurity removal devices directly solve the three major pain points in water conservancy projects—"impurity penetration, gradation imbalance, and equipment wear"—through three major technical paths: physical separation, gradation optimization, and resource recycling. Their value lies not only in improving the purity of raw materials but also in avoiding engineering quality accidents and soaring maintenance costs caused by impurities in the later stages through precise impurity removal in the early stages. Under the demand for high-quality construction of water conservancy projects, impurity removal devices have become a core standard in the raw material pretreatment process.

[0003] Against the backdrop of water conservancy projects shifting from "scale expansion" to "quality priority," granular soil raw material impurity removal devices have been upgraded from "optional equipment" to "essential systems." Their technological depth and market breadth will continue to reshape the industry landscape. In current practical applications, poor impurity removal quality may lead to residual humus, mud powder, and other fine particles clogging soil pores, resulting in excessive permeability and the formation of concentrated seepage channels. Oversized stones and metal impurities may damage the internal continuity of concrete or soil, leading to localized stress concentration. Residual oil, plastic, and other organic impurities may react with moisture and oxygen in the soil, accelerating steel corrosion or geomembrane degradation. Utility Model Content

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1:

[0027] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a particle soil raw material impurity removal device for water conservancy projects, including a mounting frame 1, a barrel body 2 mounted on the top of the mounting frame 1, a main body component 3 arranged on the outer side of the barrel body 2, a guide frame 4 opened on the inner wall of the mounting frame 1, a screening component 5 arranged on the inner wall of the mounting frame 1, and a screening frame 6 arranged on the inner wall of the screening component 5.

[0028] Mounting frame 1 provides a support point for the installation of barrel 2. Barrel 2 can temporarily store granular soil. At the same time, barrel 2 can be filled with water. The Archimedes principle of buoyancy can be used to clean the floating impurities in the granular soil, such as leaves, film, plastic and foam, in conjunction with the main component 3. The guide frame 4 can prevent the granular soil from falling outside the device and causing material waste when the limit plate 21 is opened. The screening component 5 can drive the screening frame 6 to vibrate and screen, so as to further screen the non-floating objects that were not filtered out in the first step, thereby improving the screening accuracy.

[0029] The main component 3 includes a first motor 31 fixed to the top of the barrel body 2. The output end of the first motor 31 is fixedly connected to a fixing rod 32. A fixing frame 33 and a limiting frame 34 are fixedly connected to the outside of the fixing rod 32 respectively.

[0030] The first motor 31 can drive the fixed rod 32 to rotate, and the fixed rod 32 drives the fixed frame 33 and the limiting frame 34 to rotate. The fixed frame 33 can prevent floating objects from getting stuck between soil particles and thus further improve the screening quality. The limiting frame 34 can collect floating objects on the surface of the water body, thus preventing these impurities from flowing into the next process.

[0031] The screening assembly 5 includes a second motor 51 fixed to the outside of the mounting frame 1. A connecting plate 52 is fixed to the output end of the second motor 51. A connecting rod 53 is rotatably connected to the outside of the connecting plate 52. A mounting frame 54 is slidably connected to the inner wall of the mounting frame 1, and the inner wall of the mounting frame 54 is rotatably connected to the outside of the connecting rod 53.

[0032] The second motor 51 drives the eccentric turntable, also known as the connecting plate 52, to rotate, thereby driving the connecting rod 53 to move. The connecting rod 53 drives the mounting frame 54 and the screening frame 6 to reciprocate, thereby further screening the soil particles that fall into the screening frame 6. At the same time, the moisture on the surface of the soil particles can be removed by shaking.

[0033] Example 2:

[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the inner wall of the mounting frame 1 is slidably connected to a finished product frame 7 for temporary storage of finished products, and the inner wall of the mounting frame 1 is fixedly connected to a wastewater frame 8.

[0036] The finished product frame 7 can temporarily store the sieved granular soil. Since the bottom of the finished product frame 7 is not closed, the water flowing out from the barrel 2 will fall into the wastewater frame 8 for recycling.

[0037] Specifically, two sets of pulleys 9 are rotatably connected to both sides of the mounting frame 54, and a support rod 10 is fixedly connected to the inner wall of the mounting bracket 1, with the outer side of the support rod 10 rollingly connected to the outer side of the pulley 9.

[0038] The pulley 9 and the support rod 10 work together to assist the mounting frame 54 in sliding, thereby improving the stability and smoothness of the sliding.

[0039] Specifically, a connecting block 12 is slidably connected to the inner wall of the limiting frame 34, and a fixing block 13 for scraping floating objects is fixedly connected to the outer side of the connecting block 12. The outer side of the fixing block 13 is slidably connected to the inner wall of the limiting frame 34. A first limiting rod 14 is slidably connected to the inner wall of the limiting frame 34, and a first spring 15 for limiting the first limiting rod 14 is provided on the outer side of the first limiting rod 14.

[0040] The cooperation between the connecting block 12 and the fixing block 13 facilitates the scraping of impurities floating on the surface of the water. The cooperation between the first limiting rod 14 and the first spring 15 facilitates the limiting of the connecting block 12, thereby preventing the connecting block 12 from sliding due to centrifugal force when the limiting frame 34 rotates.

[0041] Specifically, a connecting column 16 is inserted into the inner wall of the mounting frame 54, and the outer side of the connecting column 16 is slidably connected to the inner wall of the screening frame 6. A support block 17 is fixed to the top of the screening frame 6, and a second limiting rod 18 is slidably connected to the inner wall of the support block 17, and the outer side of the second limiting rod 18 is slidably connected to the inner wall of the connecting column 16.

[0042] When disassembling the screening frame 6, first pull the second limiting rod 18. The second limiting rod 18 drives the limiting plate 20 to compress the second spring 19, and at the same time disengages from the connecting column 16. Then, pull the connecting column 16 out of the mounting frame 54 and the screening frame 6. At this time, the screening frame 6 can be taken out. When installing, first put the screening frame 6 into the mounting frame 54, and then insert the connecting column 16. At this time, release the second limiting rod 18. The second spring 19 rebounds and inserts the second limiting rod 18 into the connecting column 16, thereby completing the installation of the mounting frame 54 and the screening frame 6.

[0043] Example 3:

[0044] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, a second spring 19 for limiting the second limiting rod 18 is provided on the outer side of the second limiting rod 18, and a limiting piece 20 for limiting the second spring 19 is fixedly connected to the outer side of the second limiting rod 18.

[0046] The second spring 19 can limit the second limiting rod 18, and the limiting piece 20 can limit the second spring 19.

[0047] Specifically, the inner wall of the barrel body 2 is rotatably connected to a limiting plate 21, and the outer side of the barrel body 2 is slidably connected to an insertion rod 22 for limiting the limiting plate 21, and the outer side of the insertion rod 22 is slidably connected to the inner wall of the limiting plate 21.

[0048] The limiting plate 21 can support the granular soil and water inside the barrel 2 when the first motor 31 is working. The plug rod 22 can limit the limiting plate 21 to prevent it from detaching from the barrel 2 during operation.

[0049] In operation, first fill the barrel 2 with water, then add granular soil. Start the first motor 31, which drives the fixed rod 32 to rotate. The fixed rod 32 then drives the fixed frame 33 and the limiting frame 34 to rotate. The fixed frame 33 prevents floating debris from getting stuck between the granular soil particles, thus improving screening quality. The limiting frame 34 collects floating debris from the water surface, preventing these impurities from flowing into the next process. Then, pull the first limiting rod 14 to disengage the connecting block 12. Pull the connecting block 12 to scrape away the collected impurities and remove the floating debris. Then, pull the insertion rod 22 to disengage the limiting disc 21. Pull the limiting disc 21, which rotates around the barrel 2, releasing the granular soil. The granular soil falls into the screening frame 6, while excess water falls into the wastewater frame 8. Then, start the second motor 51, which drives the eccentric turntable (connecting disc 52) to rotate. The connecting rod 53 is moved, causing the mounting frame 54 and the screening frame 6 to reciprocate, thereby further screening the soil particles falling into the screening frame 6. Simultaneously, shaking removes moisture from the surface of the soil particles. After screening, the soil particles fall into the finished product frame 7, at which point the screening frame 6 can be removed, and impurities can be poured out. During disassembly, the second limiting rod 18 is pulled first, causing the limiting plate 20 to compress the second spring 19, simultaneously... The connecting column 16 is detached and then pulled out from the mounting frame 54 and the screening frame 6. At this point, the screening frame 6 can be removed. After cleaning the screening frame 6, it can be reinstalled. First, the screening frame 6 is placed into the mounting frame 54, and then the connecting column 16 is inserted. At this point, the second limiting rod 18 is released, and the second spring 19 rebounds to connect the second limiting rod 18 with the connecting column 16, thus completing the installation of the mounting frame 54 and the screening frame 6. After all preparations are completed, the next round of screening can begin.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
