Description

Technical Field

[0001] This invention relates to the field of solid-liquid dual-purpose sampler technology, and particularly to a solid-liquid dual-purpose sampler and sampling method for zinc oxide varistor ceramic. Background Technology

[0002] Zinc oxide varistors are polycrystalline semiconductor ceramic components made primarily of zinc oxide with the addition of various metal oxides and electronic ceramic processes. They exhibit nonlinear conductivity and are key materials for suppressing overvoltage, absorbing surge energy, and providing ESD protection. The production process of zinc oxide varistors requires the use of both solid powder and liquid, and sampling and inspection are necessary during the preparation process.

[0003] A fully sealed push-pull sampler, disclosed in CN110926868A, includes a housing, a receiving box, and a sample storage box. The housing has a top cover at its front end and a sealing gland at its rear end. The sample storage box is connected to the bottom of the housing, and the receiving box is housed inside the housing. One end of the receiving box is connected to a push-pull rod passing through the top cover, and the sealing gland is connected to the receiving box. Compared with existing technologies, this invention provides a fully sealed sampler, reducing silicon powder leakage; the push-pull sampler is easy to operate, reducing the labor intensity of workers; and the sampler is in a sealed state during operation, preventing material ejection and reducing the danger of sampling operations. The above technical solution is capable of sampling liquids.

[0004] Although the above technologies can reduce powder leakage and the sampler is in a sealed state during operation, reducing the danger of sampling operations, it is impossible to determine the size of the sampled powder particles when sampling powdery objects. Furthermore, some sample residue will remain inside the sampler after sampling, making it impossible to clean the sampler. This will contaminate the remaining sample and render it unusable the next time it is used.

[0005] Therefore, it is necessary to solve the above problems by using a solid-liquid dual-purpose sampler and sampling method based on zinc oxide varistor ceramic. Summary of the Invention

[0006] The purpose of this invention is to provide a solid-liquid dual-purpose sampler and sampling method for zinc oxide varistor ceramics, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a solid-liquid dual-purpose sampler for zinc oxide pressure-sensitive ceramic, comprising a sampler body, a sampling component, and an adjustment component. The sampling component is inserted and assembled on the top of the sampler body, and the adjustment component is slidably assembled inside the sampler body.

[0008] The adjustment assembly includes an inflatable airbag and a first rotating plate. A first spring is fixedly mounted inside the first rotating plate, and a second rotating plate is fixedly mounted at one end of the first spring. The second rotating plate is slidably mounted inside the first rotating plate. A first hinge is fixedly mounted on one side of the first rotating plate, and a second hinge is fixedly mounted on one side of the second rotating plate. A sliding plate is hinged to the second rotating plate via the second hinge. A second spring is fixedly mounted on one side of the sliding plate. A limit cylinder is sleeved on the outer surface of the sliding plate. The second spring is located between the sliding plate and the limit cylinder. A pressure sensor for weighing the material inside the weighing sampler is fixedly mounted inside the first rotating plate. An exhaust pipe is fixedly connected to the inflatable airbag, and a pressure solenoid valve is fixedly mounted on the exhaust pipe.

[0009] During sampling, the particle size of the material is reflected by the detection value of the pressure sensor, and the expansion degree of the expansion bladder is adjusted according to the particle size to enable corresponding discharge operation for different material particle sizes, ensuring that the material does not remain in the sampler. After liquid sampling and discharge, gas is introduced into the exhaust pipe through the expansion bladder to dry the residual liquid and prevent the sample from being contaminated in the next use.

[0010] Preferably, the sampler body has an internal cavity that is square, a connection hole at the top of the sampler body, an air bladder storage slot inside the sampler body, and a drill bit fixedly mounted at one end of the sampler body.

[0011] Preferably, the airbag storage tank is connected to the cavity inside the sampler body, and the outer wall of the sampler body is provided with a discharge port, on which a solenoid valve is fixedly mounted.

[0012] Preferably, the first rotating plate has a first sliding groove inside, one end of the first spring is fixedly connected to the inside of the first sliding groove, the second rotating plate is slidably assembled inside the first sliding groove, the limiting cylinder is fixedly connected to the inner wall of the sampler body, and the two ends of the second spring are respectively fixedly connected to the side of the sliding plate and the limiting cylinder corresponding to each other.

[0013] Preferably, the first hinge is fixedly installed inside the sampler body, the first rotating plate is hinged to the sampler body through the first hinge, and a first sealing strip is provided on both sides of the first and second hinges. A second sealing strip is fixedly provided between the first rotating plate, the second rotating plate, the sliding plate, the limiting cylinder and the sampler body.

[0014] Preferably, the inflatable airbag is located below the second rotating plate, and an air inlet pipe and an air outlet pipe are fixedly mounted on the inflatable airbag. A miniature air pump is fixedly mounted on one end of the air inlet pipe. The inflatable airbag is installed inside the airbag storage tank, and the other end of the air outlet pipe extends out of a limiting cylinder and communicates with the inner cavity of the sampler body.

[0015] Preferably, the sampling assembly includes a telescopic cylinder and a push-pull rod, with a rubber stopper fixedly disposed on one side of the push-pull rod.

[0016] Preferably, the telescopic cylinder is fixedly mounted on the top of the sampler body, and there are two push-pull rods, which are located on both sides of the telescopic cylinder. A connecting plate is fixedly connected to one side of the telescopic cylinder, and the end of the push-pull rod away from the connecting plate is fixedly connected to the top of the rubber stopper.

[0017] Preferably, the push-pull rods are all slidably connected inside the connecting holes, the top ends of the push-pull rods are all fixedly connected to one side of the connecting plate, and the shape of the rubber stopper is adapted to the shape inside the sampler body.

[0018] A sampling method for a solid-liquid dual-purpose sampler made of zinc oxide varistor ceramic is described below, with the specific steps as follows:

[0019] Step 1: Adjust the sampler body to the initial state. In the initial state, the rubber stopper is located above the discharge port, and the adjustment component is in a horizontal state.

[0020] Step 2: Open the solenoid valve and use the telescopic cylinder to move the rubber stopper upward, allowing the sample to enter the sampler body from the outlet. When the rubber stopper rises to a certain height, stop moving and close the solenoid valve.

[0021] Step 3: Remove the sampler body and perform the sampling operation. When sampling solids, the weight of the sample is detected by the pressure sensor. Based on the difference in weight under the same volume conditions, the sample can be determined to be powder or particle size.

[0022] Step 4: Adjust the adjustment components through the controller, turn on the micro air pump, and inflate the expansion bladder through the air inlet pipe to expand the expansion bladder, so that the second rotating plate can be lifted up and the first rotating plate and the second rotating plate can be tilted, which can improve the sample discharge efficiency inside the sampler body.

[0023] Step 5: The retraction of the telescopic cylinder moves the rubber stopper downward, squeezing the sample downward and increasing the air pressure inside the sampler. This allows the sample to be discharged from the outlet, increasing the material discharge speed. At the same time, the downward movement of the rubber stopper drives the gas flow, which in turn discharges the material on the first rotating plate from the sampler body and blows out any residual sample in the sampling tube. When discharging the sample after sampling the liquid, the expansion air bladder introduces gas into the exhaust pipe to dry the residual liquid and prevent contamination of the sample in the next use.

[0024] The technical effects and advantages of this invention are as follows:

[0025] 1. This invention limits the extension stroke of the telescopic cylinder by a controller, controlling the sampling stroke to a length of L. This ensures that the rubber stopper rises to a consistent height, thus fixing the storage cavity volume within the sampler body. Therefore, the total weight of materials with different particle sizes will vary under the same volume. Specifically, the total weight of materials under the same volume, from largest to smallest, corresponds to the following particle sizes: powder, small granules, medium granules, and large granules. Thus, under the same volume, the particle size of the sampled solid can be determined by detecting the weight of the material on the first rotating plate, i.e., the particle size is reflected by the detection value of the pressure sensor.

[0026] 2. Based on the established particle size range of the material, this invention reduces the tilt angle of the first rotating plate for large particle sizes to prevent the material from being unable to be discharged due to an excessively small angle between the first rotating plate and the discharge port. Conversely, it maximizes the tilt angle of the first rotating plate for small particle sizes to prevent the material from being unable to be discharged smoothly due to an excessively large angle between the first rotating plate and the discharge port, thus ensuring that the material can be discharged smoothly at different particle sizes by utilizing its own weight.

[0027] 3. When the pressure sensor reading is within the range of values ​​for powdery materials, the material is in powder form. This can cause adhesion and retention during discharge. In this case, the controller controls a micro-pump to continuously inflate the expansion bladder through the air inlet pipe. When the gas pressure inside the expansion bladder exceeds the threshold of the pressure solenoid valve, the pressure solenoid valve opens. This allows the gas inside the expansion bladder to be discharged through the pressure solenoid valve and the exhaust pipe. The direct blowing of the gas can directly blow the material on the first rotating plate out of the discharge port, ensuring that the material on the first rotating plate is discharged smoothly without residue.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] First Embodiment

[0039] This invention provides, for example Figures 1 to 8 The sampler shown is a solid-liquid dual-purpose sampler of zinc oxide varistor ceramic, including a sampler body 1, a sampling component 2 and an adjustment component 3. The sampling component 2 is inserted and assembled on the top of the sampler body 1. The adjustment component 3 is slidably assembled inside the sampler body 1 and is located below the sampling component 2. A controller is fixedly assembled inside the sampler body 1.

[0040] The sampling assembly 2 includes a telescopic cylinder 201 and a push-pull rod 202, with a rubber stopper 203 fixedly installed on one side of the push-pull rod 202.

[0041] The telescopic cylinder 201 is fixedly mounted on the top of the sampler body 1. There are two push-pull rods 202, which are located on both sides of the telescopic cylinder 201. A connecting plate 204 is fixedly connected to one side of the telescopic cylinder 201. The end of the push-pull rod 202 away from the connecting plate 204 is fixedly connected to the top of the rubber stopper 203.

[0042] The push-pull rods 202 are all slidably connected to the inside of the connecting hole, and the top of the push-pull rods 202 are all fixedly connected to one side of the connecting plate 204. The shape of the rubber stopper 203 is adapted to the shape inside the sampler body 1.

[0043] The movement of the push-pull rod 202 is controlled by the telescopic cylinder 201, thereby controlling the movement of the rubber stopper 203. Because the shape of the rubber stopper 203 is adapted to the internal cavity of the sampler body 1, a sealed space is formed between the rubber stopper 203 and the sampler body 1. When sampling, the rubber stopper 203 moves upward, reducing the air pressure inside the sampler, thereby allowing the sample to enter the sampler. When discharging, the controller opens the solenoid valve, which causes the material to be discharged from the sampler body 1 under the action of gravity, thereby realizing the collection of the material.

[0044] The adjusting assembly 3 includes an inflatable airbag 301 and a first rotating plate 302. A first spring 303 is fixedly installed inside the first rotating plate 302. A second rotating plate 304 is fixedly installed at one end of the first spring 303. The second rotating plate 304 is slidably installed inside the first rotating plate 302. A first hinge 305 is fixedly installed on one side of the first rotating plate 302. A second hinge 306 is fixedly installed on one side of the second rotating plate 304. A sliding plate 307 is hinged to the second rotating plate 304 through the second hinge 306. A second spring 308 is fixedly installed on one side of the sliding plate 307. A limiting cylinder 309 is sleeved on the outer surface of the sliding plate 307. The second spring 308 is located between the sliding plate 307 and the limiting cylinder 309. A pressure sensor for weighing the material inside the weighing sampler is fixedly installed inside the first rotating plate 302. An exhaust pipe 3012 is fixedly connected to the inflatable airbag 301, and a pressure solenoid valve is fixedly installed on the exhaust pipe 3012.

[0045] During sampling, the particle size of the material is reflected by the detection value of the pressure sensor, and the expansion degree of the expansion bladder 301 is adjusted according to the particle size to enable corresponding discharge operation for different material particle sizes, ensuring that the material does not remain in the sampler. After liquid sampling and discharge, gas is introduced into the exhaust pipe 3012 through the expansion bladder 301 to dry the residual liquid and prevent the sample from being contaminated in the next use.

[0046] The sampler body 1 has a cavity inside, and the cavity is square. The top of the sampler body 1 has a connection hole. The sampler body 1 has an airbag storage slot 101 inside. A drill bit 102 is fixedly installed at one end of the sampler body 1.

[0047] When in use, the outer surface of the drill bit 102 is provided with spiral grooves, which can improve the drilling efficiency when sampling.

[0048] The airbag storage tank 101 is connected to the cavity inside the sampler body 1. The outer wall of the sampler body 1 is provided with a discharge port 103, and a solenoid valve is fixedly installed on the discharge port 103.

[0049] During use, the solenoid valve opens the outlet 103 to allow the sample to flow during sampling and discharge. Before and after sampling, the solenoid valve closes the outlet 103 to prevent external samples from entering the sampler.

[0050] The first rotating plate 302 has a first sliding groove inside. One end of the first spring 303 is fixedly connected to the inside of the first sliding groove. The second rotating plate 304 is slidably assembled inside the first sliding groove. The limiting cylinder 309 is fixedly connected to the inner wall of the sampler body 1. The two ends of the second spring 308 are respectively fixedly connected to the side of the sliding plate 307 corresponding to the limiting cylinder 309.

[0051] The first hinge 305 is fixedly installed inside the sampler body 1. The first rotating plate 302 is hinged to the sampler body 1 through the first hinge 305. The first hinge 305 and the second hinge 306 are provided with first sealing strips on both sides. The first rotating plate 302, the second rotating plate 304, the sliding plate 307 and the limiting cylinder 309 are all fixedly provided with second sealing strips between them and the sampler body 1.

[0052] In use, when air is inflated into the expansion bladder 301 through the air inlet pipe 3011, the expansion bladder 301 inflates and lifts the second rotating plate 304. Since the sliding plate 307 is slidably connected to the inside of the limiting cylinder 309, the second rotating plate 304 is similarly slidably connected to the inside of the first rotating plate 302. Furthermore, a second sealing strip is fixedly provided between the first rotating plate 302, the second rotating plate 304, the sliding plate 307, the limiting cylinder 309, and the sampler body 1, which can seal during movement to prevent powder or liquid inside the sampler from entering the adjusting component 3, thus improving the service life of the sampler.

[0053] The inflatable airbag 301 is located below the second rotating plate 304. An air inlet pipe 3011 and an exhaust pipe 3012 are fixedly mounted on the inflatable airbag 301. A miniature air pump is fixedly mounted on one end of the air inlet pipe 3011. The inflatable airbag 301 is installed inside the airbag storage tank 101. The other end of the exhaust pipe 3012 extends out of the limiting cylinder 309 and communicates with the inner cavity of the sampler body 1.

[0054] However, during the discharge operation, the controller controls the micro air pump to work. When the air inlet pipe 3011 inflates the expansion air bladder 301, the expansion air bladder 301 expands and can lift the second rotating plate 304, which can further increase the discharge speed of the material. At the same time, the retraction cylinder 201 can drive the rubber stopper 203 to move down, which can squeeze the sample downward and increase the air pressure inside the sampler, so that the sample is discharged from the discharge port 103, increasing the discharge speed of the material. At the same time, when the rubber stopper 203 moves down, it can drive the gas flow, which can discharge the material on the first rotating plate 302 from the sampler body 1.

[0055] Second Embodiment

[0056] In practical use, since the sampler is intended for both solid and liquid applications, it is necessary to ensure that no material remains inside after each use. However, in actual use, with the first rotating plate 302 tilted upwards, large and medium-sized particles are discharged under gravity without any residue adhering to the first rotating plate 302. However, small particles may remain during the discharge process, and relying solely on weight discharge is insufficient to meet emission standards. Furthermore, powdery materials may adhere to the walls during discharge, hindering complete discharge. This is highly detrimental to material sampling operations. Based on this, this application proposes the following improvement scheme:

[0057] During use, as the solenoid valve opens and the telescopic cylinder 201 moves upward, the material is introduced into the sampler body 1. The weight of the sample inside the sampler can be detected by a pressure sensor. During the sampling process, the telescopic stroke of the telescopic cylinder 201 is limited by the controller, and the sampling stroke is controlled within a length L. This ensures that the rubber stopper 203 rises to a consistent height, thus fixing the storage cavity volume inside the sampler body 1. Therefore, the total weight of materials with different particle sizes will be different within the same volume. That is, the total weight of materials in the same volume, from largest to smallest, corresponds to the following particle sizes: powder, small granules, medium granules, and large granules. Therefore, within the same volume, the particle size of the sampled solid sample can be determined by detecting the weight of the material on the first rotating plate 302. In other words, the particle size of the material is reflected by the detection value of the pressure sensor. Specifically:

[0058] When the pressure sensor reading exceeds the minimum threshold for medium-sized particles, it indicates that the material's particle size falls within the medium-sized range. In this case, no external force is required to force the material out of the sampler under its own weight. During discharge, the controller activates a micro-pump, inflating the expansion bladder 301 through the inlet pipe 3011. The expansion bladder 301 inflates, lifting the second rotating plate 304. The displacement of the second rotating plate 304 relative to the sliding plate 307 directly reflects the tilt angle of the first rotating plate 302. Therefore, when the particle size is large, the controller controls the expansion... The expansion of the air bladder 301 is half of the total expansion, so the tilt angle of the first rotating plate 302 is W1. This prevents the material from not being discharged due to the small angle between the first rotating plate 302 and the discharge port 103. This ensures that the material with a large particle size can be discharged by its own weight, increasing the discharge speed of the material. At the same time, no material will remain in the sampler. When the pressure sensor does not detect the material weight signal, it indicates that the material on the first rotating plate 302 has been discharged. At this time, the micro air pump performs an air extraction operation to extract the gas in the air bladder 301, causing the first rotating plate 302 to reset.

[0059] When the pressure sensor reading falls within the range for small particles, the material's particle size is relatively small. This can cause jamming and stagnation during discharge. In this case, the controller activates a micro-pump to inflate the expansion bladder 301 through the air inlet pipe 3011. The expansion of the expansion bladder 301 lifts the second rotating plate 304. The displacement of the second rotating plate 304 as it pushes the sliding plate 307 upwards directly reflects the tilt angle of the first rotating plate 302. Therefore, when the material is in the small particle size range, the controller maximizes the expansion of the expansion bladder 301, resulting in a tilt angle of W for the first rotating plate 302, where W = 2 * W1. This increases the tilt angle of the first rotating plate 302 when the material particle size is small. The angle between the first rotating plate 302 and the discharge port 103 is adjusted to prevent the material from being unable to be discharged due to an excessively large angle. This ensures that the material with a large particle size can be discharged by its own weight, increasing the discharge speed. At the same time, the controller controls the telescopic cylinder 201 to retract, which can drive the rubber stopper 203 to move downward and drive the gas flow in the sampler. This gas flow can discharge small particles of material on the first rotating plate 302 from the sampler body 1. When the pressure sensor does not detect the material weight signal, it indicates that the material on the first rotating plate 302 has been discharged cleanly. At this time, the micro air pump performs an air extraction operation to extract the gas in the expansion air bag 301, causing the first rotating plate 302 to reset.

[0060] When the pressure sensor reading is within the range for powdery materials, the material is in powder form, which can cause adhesion and retention during discharge. In this case, the controller activates a micro-pump to continuously inflate the expansion bladder 301 through the inlet pipe 3011. The expansion bladder 301 inflates, lifting the second rotating plate 304, further increasing the material discharge speed. When the gas pressure inside the expansion bladder 301 exceeds the threshold of the pressure solenoid valve, the valve opens, allowing the gas inside to be discharged through the solenoid valve and exhaust pipe 3012. The direct blowing of the gas directly expels the material from the first rotating plate 302 through the outlet 103, ensuring smooth discharge without residue. When the pressure sensor detects no material weight signal, it indicates that the material on the first rotating plate 302 has been completely discharged. At this point, the micro-pump performs a pumping operation to extract the gas from the expansion bladder 301, causing the first rotating plate 302 to reset.

[0061] Third Embodiment

[0062] This invention also provides a sampling method for a solid-liquid dual-purpose sampler of zinc oxide varistor ceramic, the specific steps of which are as follows:

[0063] Step 1: Adjust the sampler body 1 to the initial state. In the initial state, the rubber stopper 203 is located above the discharge port 103, and the adjustment component 3 is in a horizontal state.

[0064] Step 2: Open the solenoid valve and move the rubber stopper 203 upward through the telescopic cylinder 201, so that the sample enters the sampler body 1 from the outlet 103. When the rubber stopper 203 rises to a certain height, stop moving and close the solenoid valve.

[0065] Step 3: Take out the sampler body 1 and perform the sampling operation. When sampling solids, the weight of the sample is detected by the pressure sensor. Based on the difference in weight under the same volume conditions, the sample can be determined to be powder or particle size.

[0066] Step 4: Adjust the adjustment component 3 through the controller, turn on the micro air pump, and inflate the expansion air bag 301 through the air inlet pipe 3011 to expand the expansion air bag 301, so that the second rotating plate 304 can be lifted up, so that the first rotating plate 302 and the second rotating plate 304 are in an inclined state, which can improve the discharge efficiency of the sample inside the sampler body 1.

[0067] Step 5: The retraction of the telescopic cylinder 201 can drive the rubber stopper 203 to move downward, which can squeeze the sample downward, increase the air pressure inside the sampler, and thus discharge the sample from the outlet 103, increasing the material discharge speed. At the same time, the downward movement of the rubber stopper 203 can drive the gas flow, which can discharge the material on the first rotating plate 302 from the sampler body 1 and blow out the residual sample in the sampling tube. When discharging the sample after sampling the liquid, the gas is introduced into the exhaust pipe 3012 through the expansion air bladder 301 to dry the residual liquid and prevent the sample from being contaminated in the next use.

10. A sampling method for a solid-liquid dual-purpose sampler for zinc oxide varistor ceramics, the method being implemented using the solid-liquid dual-purpose sampler for zinc oxide varistor ceramics as described in claim 9, characterized in that... The specific usage steps are as follows: Step 1: Adjust the sampler body (1) to the initial state. In the initial state, the rubber stopper (203) is located above the discharge port (103), and the adjustment component (3) is in a horizontal state. Step 2: Open the solenoid valve and move the rubber stopper (203) upward through the telescopic cylinder (201) so that the sample enters the sampler body (1) from the outlet (103). When the rubber stopper (203) rises to a certain height, stop moving and close the solenoid valve. Step 3: Take out the sampler body (1) and perform sampling. When sampling solids, the weight of the sample is detected by the pressure sensor. Based on the different weights under the same volume conditions, the sample is determined to be powder and particle size. Step 4: Adjust the adjustment component (3) through the controller, turn on the micro air pump, and inflate the expansion air bag (301) through the air inlet pipe (3011) to expand the expansion air bag (301), so that the second rotating plate (304) can be lifted up, so that the first rotating plate (302) and the second rotating plate (304) are in an inclined state, thereby improving the discharge efficiency of the sample inside the sampler body (1). Step 5: The retracting cylinder (201) moves the rubber stopper (203) downward, squeezing the sample downward and increasing the air pressure inside the sampler, thereby causing the sample to be discharged from the outlet (103) and increasing the discharge speed of the material. At the same time, the rubber stopper (203) can drive the gas flow when it moves downward, so that the material on the first rotating plate (302) can be discharged from the sampler body (1) through the gas flow, and the residual sample in the sampling tube is blown out. When the liquid is sampled and discharged, gas is introduced into the exhaust pipe (3012) through the expansion air bag (301) to dry the residual liquid and prevent the sample from being contaminated in the next use.
