Description

Technical Field

[0001] This utility model relates to the field of zircon sand sampling technology, specifically an insertion-type zircon sand detection and sampling structure. Background Technology

[0002] Zircon sand is a high-density composite mineral sand widely used in refractory materials, precision ceramics, metallurgy, chemicals, casting, and other industrial fields. The zircon content, impurity composition, particle size distribution, and moisture content within the zircon sand directly determine its grade and trading price. Therefore, accurate sampling is a core prerequisite for material quality testing, trade settlement, and production control. During the storage of zircon sand, due to its high density and complex mineral composition, it is easily subject to significant particle segregation and stratification under the combined effects of gravity settling, wind erosion, rainwater infiltration, and mechanical compression. Specifically, the surface and edges of the sand pile are exposed to the external environment for extended periods, resulting in the separation of coarse and fine particles, the accumulation of low-density gangue minerals and dust impurities, and rapid moisture evaporation with large fluctuations in moisture levels. The bottom layer of the sand pile is prone to water accumulation and seepage, leading to clumping and dampness. In contrast, the material deep within the sand pile is uniformly mixed, has a stable composition, and is least affected by external disturbances, thus truly representing the original quality of the entire batch of zircon sand.

[0003] Currently, the industry primarily uses manual shovel shovels and simple straight-tube sampling methods for zircon sand pile sampling. These sampling tools are simple in structure and have certain technical limitations. First, existing sampling tools have limited sampling depth, only able to collect materials from the surface and shallow layers of the sand pile, unable to reach deeper areas near the center. The collected samples are significantly affected by material segregation, natural weathering, and external pollution, resulting in poor sample representativeness and a large deviation between the test data and the actual quality of the material, easily leading to trade settlement disputes and errors in production ingredient judgment. Second, it is impossible to perform stratified sampling of materials in single batches according to sampling and testing requirements. Utility Model Content

A vertical tube is fixed to the upper surface of the ring. A circular cover is fixed to the top end of the insert, and the vertical tube passes through the circular cover. The inner wall of the circular cover is clearance-fitted with the outer wall of the vertical tube. A vertical rod is fixed to the upper surface of the circular plate. A first knob is fixed to the top end of the vertical rod. A second knob is fitted on the upper outer wall of the vertical rod, and the inner wall of the second knob is clearance-fitted with the outer wall of the vertical rod. The second knob is fixedly connected to the top end of the vertical tube. A scale is set on the front side of the outer wall of the insert.

[0006] Preferably, it further includes: a rubber pad, the rubber pad being fixed to the surface of the baffle facing the feed inlet, the rubber pad being in contact with the inner wall of the insert, and the rubber pad being fitted to the inner wall of the insert.

[0007] Preferably, it further includes: a first mainspring, the inner ring of which is fixedly connected to the outer wall of the vertical tube, and the outer ring of which is fixedly connected to the inner wall of the insert; a second mainspring, the inner ring of which is fixedly connected to the outer wall of the vertical rod; and a sleeve, which is fixedly connected to the top of the round cover, and the inner wall of which is fixedly connected to the outer ring of the second mainspring.

[0008] Preferably, it further includes: an air suction bag, the air inlet of which is fixedly connected to the top of the first knob, the first knob having a hollow interior; two valves, one port of each valve being fixedly connected to the bottom two sides of the first knob; two first connectors, each fixedly connected to the other end of each valve; two hoses, each fixedly connected to the port of each first connector away from the valve, the hoses penetrating the round cover, the outer wall of the hoses being clearance-fitted with the through wall of the round cover; and two second connectors, each fixedly connected to the bottom end of each hose, the second connectors penetrating the round plate, the second connectors being fixedly connected to the through wall of the round plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This insertion-type zircon sand detection and sampling structure has the following advantages:

[0012] Through the coordinated operation of various components, the operator first inserts the plunger into the zircon sand pile to a suitable depth. The operator then applies force to the first knob, opening one of the feed inlets. Material at the center of the zircon sand pile enters the corresponding storage chamber through this feed inlet and is collected. Next, the operator applies force to the first knob to reset it. Then, the operator applies an outward pulling force to move the plunger. The operator can observe the scale readings on the outer wall of the plunger where it protrudes from the sand pile. Stop pulling the plunger out. Finally, the operator turns the second knob... Applying force to open the other feed port allows material from another layer in the zircon sand pile to enter another storage chamber and be collected. Then, the operator applies force to the second knob to reset it, and finally pulls out the insert to complete the removal of the zircon sand material. This method allows for sampling near the center of the zircon sand pile and enables single-batch stratified sampling of materials according to sampling and testing requirements. This enhances the representativeness of the samples, significantly reduces the deviation between the test data and the actual quality of the materials, and is less likely to cause trade settlement disputes or errors in production batching.

[0013] Through the coordinated operation of various components, the operator can continuously and intermittently press the suction bladder. The bottom of the suction bladder generates suction, creating negative pressure in the cavity inside the first knob. When material is being collected from one storage chamber, the corresponding valve above that storage chamber can be opened to create negative pressure inside the storage chamber, facilitating the smooth entry of material into the storage chamber for collection. After the collection operation is completed, the pressure on the suction bladder is stopped, and the storage chamber is allowed to equalize with the external atmospheric pressure before the feed inlet is covered to facilitate subsequent material collection operations.

[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] Please see Figures 1 to 4The technical solution provided by this utility model is as follows: an insertion-type zircon sand detection and sampling structure, comprising: an insert 1, with two feed ports 5 at the bottom of the outer wall of the insert 1; a first sealing bearing 15, which is disposed inside the insert 1; a ring 2, which is located below the inner wall of the insert 1 and is rotatably connected to the insert 1 via the first sealing bearing 15; a second sealing bearing 16, which is disposed inside the ring 2; a circular plate 3, which is rotatably connected to the inner wall of the ring 2 via the second sealing bearing 16; a partition 4, which is vertically fixed to the bottom of the insert 1 and can divide the lower interior space of the insert 1 into two storage chambers; two baffles 6, which are respectively abutted against the lower sides of the inner wall of the insert 1 and are used to block the two feed ports 5; and a first connecting rod 7. A first connecting rod 7 is fixedly connected to a ring 2 at the top of a baffle 6 away from the feed inlet 5. A second connecting rod 8 is fixedly connected to a circular plate 3 at the top of another baffle 6 away from the feed inlet 5. A vertical tube 9 is fixedly connected to the upper surface of the ring 2. A circular cover 10 is fixedly connected to the top of the insert 1. The vertical tube 9 passes through the circular cover 10. The inner wall of the circular cover 10 is clearance-fitted with the outer wall of the vertical tube 9. A vertical rod 11 is fixedly connected to the upper surface of the circular plate 3. A first knob 12 is fixedly connected to the top of the vertical rod 11. A second knob 13 is fitted on the upper outer wall of the vertical rod 11. The inner wall of the second knob 13 is clearance-fitted with the outer wall of the vertical rod 11. The second knob 13 is fixedly connected to the top of the vertical tube 9. A scale 14 is set on the front side of the outer wall of the insert 1.

[0022] In the specific implementation process, it is worth noting that the insert 1 is made of high-strength wear-resistant alloy material, which is suitable for the high physical properties of zircon sand. This can prevent wear and deformation of the cylinder wall caused by long-term insertion and extraction sampling. Both the first sealing bearing 15 and the second sealing bearing 16 are waterproof and dustproof sealed bearings, which can not only ensure smooth and unobstructed rotation of the ring 2 and the circular plate 3, but also prevent sand particles and dust from entering the bearing gap and prevent the rotating structure from jamming. The partition 4 is a hard steel plate, which is vertically fixed and has excellent sealing performance. It can completely isolate the two storage chambers and prevent zircon sand from being mixed with other materials at different layers and sampling positions. The sand sample is mixed, ensuring the independence of sample testing. Two connecting rods link the ring 2 and the circular plate 3 respectively, so that the two baffles 6 can be controlled independently without interference. This matches the operational requirements of alternating layered sampling. The circular cover 10 serves to seal the top of the tube and protect the internal transmission structure. The clearance fit installation method can eliminate the rotational friction resistance of the vertical tube 9 and the vertical rod 11. The clearance fit refers to a fit with a gap (including a minimum gap of zero). The scale 14 on the outer wall of the tube 1 is laser etched, which is clear, wear-resistant, and free from fading or blurring. This accurately assists the operator in controlling the layered sampling interval.

[0023] Furthermore, it also includes: a rubber pad, which is fixed to the surface of the baffle 6 facing the feed inlet 5, and the rubber pad is in contact with the inner wall of the insert 1.

[0024] In the specific implementation process, it is worth noting that the rubber pad is made of wear-resistant and highly elastic nitrile rubber. When the baffle 6 closes to block the feed inlet 5, it can fill the tiny gap between the baffle 6 and the inner wall of the insert 1, thereby improving the blocking effect of the baffle 6 on the feed inlet 5.

[0025] Furthermore, it also includes: a first mainspring 17, the inner ring of which is fixedly connected to the outer wall of the vertical tube 9, and the outer ring of which is fixedly connected to the inner wall of the insert 1; a second mainspring 18, the inner ring of which is fixedly connected to the outer wall of the vertical rod 11; and a sleeve 19, which is fixedly connected to the top of the round cover 10, and the inner wall of which is fixedly connected to the outer ring of the second mainspring 18.

[0026] In the specific implementation process, it is worth noting that both the first spring 17 and the second spring 18 are made of high-toughness spring steel strip, which has the characteristics of stable rebound and high fatigue strength. They are suitable for repeated rotation and reset working conditions. The first spring 17 is used to match the rotation of the vertical tube 9 and the ring 2. After the operator rotates the second knob 13 to complete the sampling, the elastic torque of the spring can drive the vertical tube 9 to automatically rotate and reset, realizing the automatic closure of the corresponding baffle 6. The second spring 18 is adapted to the rotation structure of the vertical rod 11 and the circular plate 3. After rotating the first knob 12 to take samples, it can drive the vertical rod 11 to automatically rebound and reset, eliminating the need for manual rotation of the knob and simplifying the operation process. The sleeve 19 provides a fixed limit for the second spring 18 to ensure the stability of the spring installation, prevent the spring from being deflected or deformed by force, and ensure the automatic reset function during long-term use.

[0027] Furthermore, it also includes: an air suction bag 20, the air intake end of which is fixed to the top of the first knob 12, the interior of the first knob 12 being a hollow structure; valves 21, two valves 21, one port of each valve 21 being fixed to the bottom two sides of the first knob 12; first connectors 22, two first connectors 22, each fixed to the other end of each valve 21; hoses 23, two hoses 23, each fixed to the port of each first connector 22 away from the valve 21; hoses 23 penetrating the round cover 10, the outer wall of hoses 23 being clearance-fitted with the through wall of the round cover 10; and second connectors 24, two second connectors 24, each fixed to the bottom end of each hose 23; second connectors 24 penetrating the round plate 3, the second connectors 24 being fixedly connected to the through wall of the round plate 3.

[0028] In practical implementation, it is worth noting that the suction bag 20 is made of flexible, wear-resistant rubber, which can be repeatedly pressed and deformed to continuously generate negative pressure suction. To facilitate understanding, a simple explanation of the working principle of the suction bag 20 is provided. The structure of the suction bag 20 is similar to the compression bag structure of a manual mercury sphygmomanometer, employing a flexible bag body combined with a built-in mechanical one-way valve. The difference is that the sphygmomanometer's bag inflates in the forward direction, while this device is installed in reverse, depressurizing by suction. The suction bag 20 has two sets of mechanical one-way valves embedded inside: an inlet one-way valve and an outlet one-way valve, forming a backflow-preventing closed airway. When the suction bag body is manually pressed, the bag body compresses and deforms, closing the inlet one-way valve and opening the outlet one-way valve, allowing air to escape from the bag. Air is quickly expelled outwards. After the pressure is released, the flexible bladder rebounds and recovers on its own elasticity. At this time, the exhaust one-way valve closes and the intake one-way valve opens automatically. Air inside the storage chamber, hose 23, and hollow first knob 12 is drawn into the bladder. This cycle repeats continuously, continuously pumping out air from the sealed space. Two sets of independent valves 21 correspond to the two storage chambers respectively, and can control the negative pressure of a single chamber independently to avoid sample cross-contamination caused by negative pressure interconnection. The operator can open the corresponding valve 21 according to the open inlet 5. The hose 23 is made of polyurethane hose with excellent bending resistance and air tightness, which is adapted to the movement trajectory of the internal transmission structure. The sufficient length of the hose can avoid the pulling interference when the vertical rod 11 and vertical pipe 9 rotate, ensuring smooth and stable air passage.

[0029] Furthermore, it also includes: a filter cover, which is fixed to the bottom end of the second connector 24.

[0030] In the specific implementation process, it is worth noting that the filter cover is made of high-density stainless steel microporous filter screen. The filter screen pore size is smaller than the minimum particle size of zircon sand. During the negative pressure sampling process, it can effectively intercept sand particles and prevent zircon sand from entering the hose 23 and the air extraction bag 20 with the airflow.

[0031] Furthermore, it also includes: a conical head 25, which is fixed to the bottom end of the insert 1, and the outer wall of the conical head 25 is provided with a spiral groove 26.

[0032] In the specific implementation process, it is worth noting that the conical head 25 is made of thickened hard alloy material, which has high hardness and strong impact resistance. The pointed conical structure can reduce the resistance of the insert 1 when inserted into the sand pile, making it easier to quickly penetrate the dense zircon sand pile. The spiral grooves 26 opened on the outer wall are distributed in an equidistant spiral. During the insertion and extraction of the insert, the spiral grooves can loosen and guide the surrounding sand, reducing the squeezing resistance of the sand on the insert.

[0033] Working principle:

[0034] Insertion positioning sampling:

[0035] During sampling, the operator holds the inserter 1 and inserts the end with the conical head 25 into the zircon sand pile to be sampled to a suitable depth, so that the feed inlet 5 is located as close as possible to the center of the sand pile to ensure that the sample comes from the core area of ​​the sand pile. Then, force is applied to the first knob 12, which drives the vertical rod 11 and the circular plate 3 to rotate. Through the transmission of the second connecting rod 8, one of the baffles 6 revolves around the vertical rod 11 at a certain angle, opening the corresponding feed inlet 5. The material in the center of the sand pile enters the corresponding storage chamber through the feed inlet 5 under its own weight and is collected. After sampling is completed, force is applied to the first knob 12 to reset it, and the baffle 6 covers and seals the feed inlet 5 again.

[0036] Stratified moving sampling:

[0037] After the first layer of sampling is completed, the operator applies an outward pulling force to the insert 1, causing it to move vertically along the sand pile. The distance moved is the stratified sampling interval. The operator can control the pulling distance by referring to the scale 14 reading on the outer wall of the insert 1 where it protrudes from the sand pile, so as to determine the distance value between two sampling points. When the moving distance reaches the designated layer, the pulling is stopped, and the second knob 13 is applied to drive the vertical tube 9 and the ring 2 to rotate. Through the transmission of the first connecting rod 7, the other baffle 6 revolves around the vertical tube 9 at a certain angle, opening the other feed port 5. The material at this layer enters the other storage chamber through the other feed port 5 and is collected. After the sampling is completed, the second knob 13 is applied to reset it, and finally the insert 1 is completely pulled out, completing the stratified sampling operation of the multi-layer material.

[0038] Negative pressure assisted feeding:

[0039] During the sampling process, the operator can continuously and intermittently press the suction bag 20. The bottom of the suction bag 20 generates suction, which creates negative pressure in the cavity inside the first knob 12 through the pipeline and is transmitted to the storage chamber that is currently open. At this time, the valve 21 corresponding to the storage chamber on this side is opened, so that a negative pressure environment is created inside the storage chamber. With the assistance of the negative pressure suction, the zircon sand material can enter the storage chamber more smoothly through the feed port 5 to complete the collection.

[0040] Sampling advantages explained:

[0041] By inserting and pulling out the insert 1 layer by layer in conjunction with the alternating opening and closing of the double baffles 6, single-batch stratified sampling can be achieved near the center of the zircon sand pile. The collected samples are less affected by material segregation, natural weathering, and external pollution, and the representativeness of the samples is significantly enhanced. The deviation between the test data and the actual quality of the material is significantly reduced. After the collection operation is completed, stop pressing the air bladder 20 and wait a moment for the air pressure inside the storage chamber to be equal to the external atmospheric pressure before sealing the feed port 5 to facilitate the smooth progress of subsequent sampling operations.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
