Description

Technical Field

[0001] This utility model relates to the technical field of soil storage devices, specifically a soil storage device with solid-liquid separation storage. Background Technology

[0002] In fields such as environmental remediation, agricultural research, or construction sites, it is often necessary to temporarily store soil samples or contaminated soil collected on-site. These soils are often quite moist and will produce leachate during storage. Soil storage devices with solid-liquid separation storage functions are designed to solve this problem. They can separate and collect the liquid in the soil at the beginning of storage, preventing the soil from decaying and deteriorating due to long-term soaking, and maintaining the original state of the soil. At the same time, it is also convenient to conduct subsequent analysis or treatment of leachate and solid soil separately.

[0003] In existing technologies, most existing devices use static infiltration, where soil is placed into a container with a filter screen and the liquid slowly seeps out by gravity. This method has an extremely slow separation speed, and when the soil is viscous, it is difficult for water to be extracted, resulting in incomplete solid-liquid separation and affecting subsequent storage and processing efficiency. Because it is static separation, unloading and the next operation can only be carried out after a single batch of soil has been separated, which cannot achieve continuous feeding, separation and discharge. This seriously limits the processing capacity, and the manual loading and unloading is labor-intensive and out of step with modern continuous processing procedures. Utility Model Content

[0004] The purpose of this invention is to provide a soil storage device with solid-liquid separation storage to solve the problems of slow static infiltration separation and inability to work continuously mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a soil storage device with solid-liquid separation storage, including a base plate, a collection cylinder mounted on the base plate, an inlet mounted on the collection cylinder, an outlet mounted on the collection cylinder for discharging liquid, a collection tank mounted on the outlet, a separation cylinder rotatably connected to the collection cylinder for separating water from the soil, a conveying component mounted on the inlet, a driving component mounted on the collection cylinder, and a collection component mounted on the collection cylinder for collecting soil. The driving component drives the separation cylinder together with the soil inside to rotate, while the conveying component drives the soil to move inside the separation cylinder.

[0006] In a preferred embodiment of this technical solution, the collecting cylinder has a slot at the corresponding position of the separating cylinder, and the separating cylinder rotates inside the slot.

[0010] In a preferred embodiment of this technical solution, the collection component includes a storage box mounted on a base plate, a collection chamber mounted on the storage box, and a guide pipe mounted between the storage box and the collection cylinder.

Detailed Implementation

[0020] 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.

[0021] In many important fields such as environmental remediation, agricultural research, and construction sites, it is often necessary to temporarily store soil samples collected on-site or contaminated soil during various tasks. In environmental remediation, to accurately determine the degree, extent, and types of soil pollution in contaminated areas, staff need to collect a large number of soil samples from different locations. These samples must be properly stored temporarily before being sent to the laboratory for detailed testing and analysis to ensure that the test results accurately reflect the original condition of the soil. In agricultural research, researchers also collect various soil samples to study the fertility, composition, and impact of soil on crop growth in different regions. These samples also require temporary storage to provide a reliable sample basis for subsequent experimental research. At construction sites, contaminated soil may be encountered during construction, and temporary storage is also an essential step before further processing or transportation of this soil.

[0022] However, soil samples requiring temporary storage often have high moisture content due to the sampling environment. During storage, moisture gradually seeps out, forming leachate. If this leachate is not effectively treated, it will remain in contact with the soil for extended periods, causing the soil to be soaked and easily leading to soil decay and deterioration. This damages the soil's original physical structure and chemical composition, altering the original state of soil samples used for environmental remediation testing or agricultural research, thus affecting the accuracy of subsequent test results and the reliability of research data. For contaminated soil from construction sites, the presence of leachate can also cause pollutants to spread, increasing the difficulty and risk of subsequent treatment. To address this problem during temporary soil storage, soil storage devices with solid-liquid separation storage capabilities have been developed.

[0023] This soil storage device, with its solid-liquid separation and storage function, is designed to quickly and effectively separate the liquid contained in the soil during the initial stage of soil storage, and then collect and store the separated liquid separately. This solid-liquid separation and separate storage effectively prevents the soil from decaying due to continuous immersion in leachate throughout the storage period, preserving the original physical properties, chemical composition, and biological characteristics of the soil to the greatest extent possible. This ensures that subsequent soil testing and analysis, as well as further treatment, can be conducted based on the soil's true original state. Furthermore, collecting the leachate and solid soil separately greatly facilitates their individual treatment. For example, in environmental remediation, workers can conduct specialized testing on the separated leachate to accurately determine the content and types of pollutants, while simultaneously carrying out targeted treatment of the solid soil. In agricultural research, researchers can analyze the components of the leachate and solid soil separately to study the soil's characteristics in greater depth.

[0024] In the existing technological system, to achieve solid-liquid separation during soil storage, a series of soil storage devices with solid-liquid separation functions have been developed and applied. These devices, while meeting basic storage requirements, also address leachate treatment to some extent. One common technical solution is static infiltration to achieve solid-liquid separation. Soil storage devices using this technology typically include a container with a filter screen, which is usually positioned inside the container, forming the key structure for solid-liquid separation. In actual use, workers first load the soil to be stored into the container with the filter screen. The liquid in the soil, under its own gravity, slowly permeates through the filter screen, thus separating from the solid soil. The separated liquid is collected and stored through a collection structure below the filter screen, while the solid soil is trapped above the filter screen, completing the solid-liquid separation and separate storage of the soil. This static infiltration method for soil storage is designed based on utilizing the natural permeability of liquid in the soil, achieving the basic function of solid-liquid separation through a simple and reliable filter structure and gravity. In practical applications, these devices can meet the solid-liquid separation requirements for temporary soil storage under certain conditions. For example, for soil samples with relatively low moisture content, loose soil particles, and low clumping, their solid-liquid separation effect can meet basic usage requirements. Furthermore, these devices have a relatively simple structure, low manufacturing cost, and are easy to operate. Staff can master their use after simple training. Therefore, they are widely used in scenarios where solid-liquid separation efficiency requirements are not high and processing volumes are relatively small, such as soil sample storage in small agricultural research laboratories and temporary storage after small-scale environmental monitoring sampling.

[0025] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a soil storage device with solid-liquid separation and storage, including a base plate 21, a collection cylinder 22 mounted on the base plate 21, an inlet 23 mounted on the collection cylinder 22, an outlet 24 mounted on the collection cylinder 22 for discharging liquid, a collection tank 25 mounted on the outlet 24, a separation cylinder 26 rotatably connected to the collection cylinder 22 for separating water from the soil, a conveying component mounted on the inlet 23, a driving component mounted on the collection cylinder 22, and a collection component mounted on the collection cylinder 22 for collecting soil. The driving component drives the separation cylinder 26 together with the soil inside to rotate, while the conveying component drives the soil to move inside the separation cylinder 26. The rotation of the separation cylinder 26 by the driving component generates centrifugal force, forcibly separating water from the soil. At the same time, the conveying component pushes the soil to move inside the cylinder, realizing continuous operation of feeding, centrifugal dewatering and discharging, completely changing the problem of low efficiency of traditional static infiltration and greatly improving the processing capacity.

[0026] Please see Figure 2 A further solution based on this embodiment is as follows: the collecting cylinder 22 has a slot at the corresponding position of the separating cylinder 26, and the separating cylinder 26 rotates inside the slot. A bearing or wear-resistant bushing can be installed in the slot to provide stable rotation support for the separating cylinder 26. This not only ensures the concentricity and stability of the separating cylinder 26 when it rotates, but also effectively reduces the friction and wear between the rotating parts and the fixed parts, thus extending the service life of the equipment.

[0027] Please see Figure 2 - Figure 3 A further solution based on this embodiment is as follows: the conveying assembly includes a first motor 31 installed on the feed inlet 23, a rotating shaft 32 fixedly connected to the output end of the rotating shaft 32 and rotatably connected to the feed inlet 23, and a blade assembly installed on the rotating shaft 32. The rotating shaft 32 drives the blade assembly to rotate, and the blade assembly drives the soil to move inside the separation cylinder 26. The first motor 31 drives the rotating shaft 32 and the blade assembly to rotate, and applies the spiral propulsion force to the soil, so that it is stably conveyed from the feed end to the discharge end. This mechanical conveying method not only ensures the continuity of processing, but also stirs and loosens the soil during the conveying process, which is conducive to more fully separating water by combining centrifugal force. Moreover, the rotation speed of the blade assembly is less than the rotation speed of the separation cylinder 26.

[0028] Please see Figure 3A further embodiment of this solution is as follows: the blade assembly includes a first spiral blade section 33 mounted on the rotating shaft 32, a second spiral blade section 34 mounted on the rotating shaft 32, and a rubber strip 35 mounted on the first spiral blade section 33 and the second spiral blade section 34. The pitch of the first spiral blade section 33 is greater than the pitch of the second spiral blade section 34. The first spiral blade section 33 adopts a large pitch design and is located at the feed end, mainly to achieve rapid material conveying and preliminary loosening of the soil. The second spiral blade section 34 adopts a small pitch design and is located in the dewatering section. By increasing the soil residence time and the squeezing action, it promotes deep dewatering. The rubber strip 35 can be made of wear-resistant food-grade rubber, which flexibly contacts the inner wall of the separation cylinder 26, which can scrape off the adhering soil to prevent blockage and will not excessively wear the cylinder wall.

[0029] Please see Figure 2 , Figure 5 A further solution based on this embodiment is as follows: the drive assembly includes a second motor 41 mounted on the collection cylinder 22, a first gear 42 fixedly connected to the output end of the second motor 41, and a second gear 43 meshing with the first gear 42. The second gear 43 is fixedly connected to the separation cylinder 26. This gear transmission mechanism efficiently transmits the power of the second motor 41 to the separation cylinder 26. By selecting different gear ratios, the working speed of the separation cylinder 26 can be easily matched and adjusted to obtain the best centrifugal dehydration effect. The gear transmission has the advantages of compact structure, accurate transmission ratio, and large torque.

[0030] Please see Figure 1 , Figure 4 - Figure 5 A further solution based on this embodiment is as follows: the collection component includes a storage box 51 installed on the base plate 21, a collection chamber 52 installed on the storage box 51, and a guide pipe 53 installed between the storage box 51 and the collection cylinder 22. The guide pipe 53 serves as a transfer channel for the dehydrated soil, and its inclination angle is designed to ensure that the soil can smoothly slide into the collection chamber 52 below by gravity. The storage box 51 and the collection chamber 52 are usually designed as drawers or openable types to facilitate the removal of the treated dry soil for subsequent operations or transportation.

[0031] Please see Figure 4 A further solution based on this embodiment is as follows: the separating cylinder 26 has a matching groove at the corresponding position of the guide pipe 53, and the guide pipe 53 is embedded inside the groove. This embedded connection forms an effective sealing and guiding interface between the discharge port of the separating cylinder 26 and the guide pipe 53. It can prevent soil from splashing or leaking during discharge, ensuring that all materials are accurately guided into the collection bin 52.

[0032] Working principle: During operation, wet soil is continuously added through the feed inlet 23. The first motor 31 is started, driving the rotating shaft 32 and the first and second sections of the spiral blades 33 and 34 to rotate, pushing the soil into the separation cylinder 26. At the same time, the second motor 41 is started, driving the separation cylinder 26 to rotate at high speed through the meshing transmission of the first gear 42 and the second gear 43. The soil rotates with the cylinder wall inside the separation cylinder 26 and is subjected to strong centrifugal force. The water contained in the soil is forced to pass through the filter holes on the wall of the separation cylinder 26 and enter the cavity of the collection cylinder 22. Then, it flows into the collection tank 25 through the liquid outlet 24 for collection. Under the continuous push of the spiral blades, the dehydrated soil is gradually transported to the discharge port at the end of the separation cylinder 26 and slides into the collection bin 52 below through the guide pipe 53 for storage. The soil can be transported by pulling out the collection bin 52. The whole process realizes the continuous feeding of wet soil, dynamic centrifugal dehydration, and continuous discharge and collection of dry soil.
