Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wet screening instruments, in particular to a soil aggregate screening device. Background Art
[0002] Wet aggregate analysis refers to the classification of soil aggregates by wet sieving to determine the water stability of aggregates. Wet sieving refers to the dispersion and size classification of soil particles or aggregates under the action of water flow, that is, sieves with different sizes are connected in sequence in a bucket, moved up and down at a certain speed for a certain period of time, and then the soil samples left on each sieve are taken out, dried and weighed to obtain the distribution of particle size.
[0003] Currently, there are two main methods for wet screening of soil aggregates: manual wet screening and mechanical wet screening. The disadvantage of manual wet screening is that it requires high labor costs and there are large errors in the experimental results. Mechanical wet screening can save manpower and reduce experimental data errors, thus obtaining more accurate experimental data.
[0004] Current mechanical wet screening instruments also have certain problems. Mechanical wet screening instruments can collect soil particles larger than a certain particle size, or soil particles within a certain range. When all soil particles smaller than a certain particle size are recovered, because wet screening needs to be performed in running water, the volume of wet screening solvent will be too large, which will result in high time and labor costs during subsequent drying and weighing. Because soil particles need to be dried after wet screening, they need to be transferred after wet screening. Experimental errors are easily generated during the transfer of soil particles, resulting in inaccurate experimental data. Utility Model Content

[0025] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0027] The utility model provides a soil aggregate screening device, such as Figure 1-5 As shown, it includes a base 8, on which a control panel (not shown) is provided, wherein:
[0028] A stacking screen 6 is fixedly connected to the top of the base 8 by a fixing device. The stacking screen 6 includes at least two filter screens 14 which are connected in sequence up and down and whose particle sizes decrease from top to bottom. A vibrator (not shown) is provided on the base 8 for driving the stacking screen 6 to vibrate up and down. A water inlet 2 is provided on the topmost filter screen 14 of the stacking screen 6. A receiver 7 for collecting liquid is provided below the stacking screen 6 in the base 8. A water collector 10 is provided below the receiver 7 in the base 8. A water pump 11 is connected to the bottom of the water collector 10, and the water pump 11 is connected to the water inlet 2 through a hose 12.
[0029] Furthermore, a window 15 is provided on the side of the stacking screen 6 below each filter 14, and a first heating plate 17 is detachably connected to the window 15. A second heating plate 16 is provided below the water collector 10 in the base 8, and a control panel controls the connection of the vibrator, the water pump 11, the first heating plate 17 and the second heating plate 16.
[0030] When in use, a certain volume of wet screening solvent is introduced into the water collector 10, soil aggregates are placed on the top (uppermost) filter / screen 14 of the stacking screen 6, and the stacking screen 6 is fixedly connected by a fixing device; at the beginning of the experiment, the wet screening solvent is pumped from the water outlet of the water collector 10 through the water pump 11 through the hose 12 into the water inlet 2 of the top filter 14 to wet the soil aggregates, the vibrator drives the stacking screen 6 to vibrate up and down, the soil aggregates begin to be wet-screened, the wet screening solvent flows out from the bottom receiver 7, is collected in the water collector 10, and is re-pumped into the set screen / stacking screen 6 through the hose 12 through the water pump 11, and circulates (see Figure 1 ); After the wet screening is completed, the vibrator stops vibrating, the (sliding) window 15 on the side of the stacking screen 6 is opened, and the first heating plate 17 is placed to heat and dry the soil particles in situ, and at the same time, the second heating plate 16 under the water collector 10 is opened to heat and dry the liquid in the water collector 10 to complete the intelligent wet screening of soil aggregates.
[0031] When the existing wet screening device is used for soil wet screening, it is generally connected to the faucet by a hose and continuously rinsed with running water, which will cause all the running water to be contained in the minimum particle size collector. Finally, all the water needs to be evaporated to weigh the mass of the minimum particle size and calculate the content. Due to the large volume of water in the minimum particle size collector, the heating and evaporation process is very time-consuming and energy-consuming.
[0032] To solve the above problems, in the utility model, a certain amount of water or other liquid can be added to the water collector 10 according to the scale as needed, that is, the wet screening solvent in the water collector 10 is in a constant volume state, and then the soil aggregates are repeatedly eluted by the water pump 11, so that the wet screening solvent in the minimum particle size collector (that is, the water collector 10) is quantitative and easier to dry.
[0033] The soil aggregate screening device of the utility model has a water pump at the bottom water outlet of the water collector, and the water pump is connected to the water inlet of the uppermost filter of the stacking screen through a hose, so that the wet screening can be carried out in a flowing water environment, and the quantification of the wet screening solvent can be ensured. When collecting particles smaller than a certain particle size, the phenomenon of too much solvent being difficult to dry will not occur; the side of the stacking screen is provided with a window under each filter, and a first heating plate is detachably connected in the window, and a second heating plate is provided in the base under the water collector, and the soil particles on the filter and the soil particles in the water collector are respectively heated in situ by the first heating plate and the second heating plate, and the soil particles are dried by the in situ heating, and the process can reduce the experimental error caused by the soil particles in the transfer process to ensure the accuracy of the experimental data; the control panel on the base controls the connection of the vibrator, the water pump, the first heating plate and the second heating plate for driving the stacking screen to vibrate up and down, so as to realize intelligent control and efficiently carry out intelligent wet screening of the soil aggregates.
[0034] The utility model specifically relates to a wet screening instrument, which is specifically designed as a soil aggregate intelligent wet screening device with quantitative liquid circulation and in-situ screen heating. Soil with different particle sizes can be screened and recovered, soil with a particle size smaller than the filter can be collected, and the quality of the processed soil will not be lost during the cleaning process; windows are provided on the side of the stacking screen below each filter, and a first heating plate is detachably connected in the window, so that filtered soil particles are directly heated and dried in-situ, and while heating, soil with different particle sizes is prevented from falling into the filter of the next particle size due to water evaporation, thereby affecting experimental data.
[0035] The fixing device can adopt various structural forms that can be easily thought of by those skilled in the art, such as a fixing splint, etc. However, for the convenience of implementation and firm fixation, the present invention preferably adopts the following structural forms:
[0036] like Figure 1 As shown, a pair of fixing rods 5 can be provided on the base 8 on both sides of the stacking screen 6, and a pressure plate 1 for pressing on the top of the stacking screen 6 is slidably connected to the pair of fixing rods 5. The pair of fixing rods 5 are respectively provided with fixing parts 18 for pressing the pressure plate 1 downward to fix the stacking screen 6. The pair of fixing rods 5, the pressure plate 1 and the fixing parts 18 together constitute a fixing device.
[0037] Further, the pressing plate 1 may include a pressing plate body and lugs 19 located on both sides of the pressing plate body, the lugs 19 are respectively slidably connected to a pair of fixing rods 5, and a handle 3 is provided on the outer side of the lugs 19 to facilitate the operation of the pressing plate 1. The fixing member 18 is preferably a knob, and it is conceivable that the fixing member 18 may also be a fixing screw that squeezes the pressing plate 1 from the side. The pair of fixing rods 5 may be round-headed rods.
[0038] When assembling the stacking screen 6, the filter screens 14 are connected up and down in sequence according to the aperture / particle size to form the stacking screen 6, and then the handle 3 is used to drive the pressing plate 1 to slide downward on the pair of fixed rods 5 to press the stacking screen 6, and then the knob is used to lock the pressing plate 1 to ensure that the multiple layers of the stacking screen 6 are tightly connected, so that the entire wet sieving device is airtightly connected. The stacking screen 6 can include 3-5 filter screens 14.
[0039] During the research process, the utility model found that after wet screening, the soil particles on each layer of the screen need to be transferred to a flat dish and placed in a drying box for drying. However, since the soil particles are wet, some of them remain in the gaps of the screen during the transfer process, and some stick to the screen wall. In short, they cannot be completely transferred, so the subsequent calculation of the particle size and weight is inaccurate and has errors.
[0040] To solve this problem, Figure 3 As shown, the first heating plate 17 in the present invention also serves as a receiver for receiving soil particles that fall from the corresponding filter screen 14 after heating. In this way, in the present invention, wet soil particles do not need to be transferred, and the soil particles can be dried in situ by the first heating plate 17. The particles after drying are very easy to transfer completely, and the particles remaining in the pores of the screen 14 will become smaller in volume after drying and fall directly onto the first heating plate 17. In this way, the sum of the particle sizes in the filter screen 14 and those falling on the first heating plate 17 is the total mass of a certain screening particle size. Compared with the existing wet screening device, the experimental data is more accurate.
[0041] Continue as Figure 1 As shown, the receiver 7 may be funnel-shaped to facilitate the collection of wet screen solvent. A scale may be provided on the side wall of the water collector 10 to accurately see the volume of liquid in the water collector 10. A spray humidification nozzle 4 may be provided at the water inlet 2 to spray evenly and facilitate wetting of soil aggregates.
[0042] A water flow sensor 9 for sensing the water flow can be provided at the water outlet below the receiver 7, which is convenient for sensing the water flow and serves to give an alarm and protect the instrument. During the use of the instrument, the following situations may occur: 1) If the fixed volume of water in the water collector 10 is too little, the soil aggregates may absorb all the water in the process of water flowing down from the top filter / screen, and there will be no water for circulation. The water flow sensor 9 can alarm and prompt that a certain amount of water needs to be added to the water collector 10; 2) If you forget to add water to the water collector 10, the water flow sensor 9 can give an alarm to prevent the water pump 11 from idling and burning out. The specific structure of the water flow sensor 9 can adopt the common knowledge in the field and will not be repeated here.
[0043] Further, such as Figure 2 and Figure 5 As shown, the stacking screen 6 can be provided with a clip 13, and the clip 13 is a spring sheet with springs on the left and right, which can better fix the stacking screen 6 on the fixing rod 5. The vibrator also vibrates the stacking screen 6 left and right through the clip 13. In this way, when the stacking screen 6 is blocked and the water flow sensor 9 senses that no water flow is detected, the vibrator can vibrate the stacking screen 6 left and right through the clip 13, which helps to reduce the blockage of the stacking screen 6 and ensure that the wet screening continues.
[0044] The utility model can use a vibrator to control the up and down vibration of the stacking screen 6, and vibrate the stacking screen 6 left and right through the clip 13; it can also use two vibrators to control the up and down vibration of the stacking screen 6 and vibrate the stacking screen 6 left and right through the clip 13. In specific implementation, the base 8 can be provided with a left and right vibrator and an up and down vibrator. When the water flow is normal, it vibrates up and down, and when the water flow sensor detects that there is no water flow, it vibrates left and right. The clip 13 can be extended left and right to ensure the left and right vibration. The specific structure of the vibrator can adopt the common knowledge in the field, which will not be repeated here.
[0045] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
