Description

Technical Field

[0001] This utility model belongs to the field of silica production equipment, and specifically relates to an automatic sampling mechanism for silica reaction kettles. Background Technology

[0002] As an important chemical additive, silica is widely used in rubber, coatings, toothpaste and other fields. During its production, in order to ensure that the product quality meets the requirements, it is often necessary to sample and inspect the liquid in the reaction vessel. However, the existing technology often uses tools to insert into the sampling port for sampling, sampling valves to open directly for sampling, and pump extraction for sampling. Among these, manual sampling is less safe and can easily affect the internal environment of the reaction vessel and cause safety hazards to personnel. Sampling valves to open directly for sampling requires high valve quality and is prone to loss and danger due to valve damage. It is also limited by the position of the valve and the material in the reaction vessel, resulting in low sampling accuracy. Simply using pump extraction for sampling can easily leave material residue in the pipeline, affecting the accuracy of subsequent sampling, and it is also difficult to control the amount of sample taken. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To overcome the shortcomings of existing technologies, an automatic sampling mechanism for silica reactors is proposed. This addresses the issues that current technologies often employ sampling methods such as inserting tools into the sampling port, directly opening a sampling valve, or using a pump. Manual sampling is considered unsafe, potentially affecting the reactor's internal environment and posing safety hazards. Direct valve sampling requires high-quality valves, is prone to damage and loss, and is limited by the valve and material position within the reactor, resulting in low sampling accuracy. Simple pump sampling can leave material residue in the pipeline, affecting subsequent sampling accuracy, and makes it difficult to control the sample quantity.

[0005] (II) Technical Solution

[0006] This utility model achieves a sampling mechanism for a reaction vessel that is highly safe, has high sampling and detection accuracy, and can reduce the influence of the external environment during sampling through the following technical solution:

The top of the sample outlet hood is connected to the discharge end of the pump via a pipe, and the bottom of the sample outlet hood is connected to the reaction vessel via a pipe. The side end face of the sample outlet hood is provided with a sampling hood and a vent. A filter plate for sealing is provided at the vent. The sampling hood communicates with the sample outlet hood. The bottom of the sampling hood is provided with a sample outlet connector for communicating with the outside. The sampling container is located inside the sampling hood and the sample outlet hood. The drive mechanism is used to drive the sampling container to move within the sampling hood and the sample outlet hood.

[0010] The sampling container has a sampling groove extending through the top, and a sampling port communicating with the sampling groove is located at the bottom of the sampling container. The sampling container also has a sliding groove, one end of which covers the sampling port. A sampling cover is slidably fitted into the sliding groove. A switch plate is fixed to the bottom of the sampling cover, with its bottom passing through the sampling port and below the bottom of the sampling container. A limit plate is also fixed to the bottom of the sampling container. An elastic element is provided between the limit plate and the switch plate. The elastic element is used to drive the sampling cover to seal the sampling port via the switch plate. A top plate is fixed inside the sampling cover. The top plate is used to press against the switch plate and drive the sampling cover to open the sampling port after the sampling container has entered the sampling cover to a certain distance.

[0011] Furthermore, the sampling mechanism also includes a balance bar, one end of which is fixed to the switch plate, and the other end of which passes through the limiting plate.

[0012] Furthermore, the sampling hood includes an inlet, a top cover, a middle cover, a bottom cover, and an outlet. The bottom cover is funnel-shaped and covers and fits over the bottom of the middle cover. The top cover is embedded in the top of the middle cover, and the inlet is provided on the top cover. The middle cover is provided at the bottom of the bottom cover.

[0013] Furthermore, the connection points between the middle cover, the bottom cover, and the top cover all adopt a staggered structure with an inner bottom and an outer height.

[0014] Furthermore, the sampling mechanism also includes an electrically controlled valve and a sensor. The electrically controlled valve is electrically connected to the sensor, the electrically controlled valve is assembled on the sample outlet connector, and the sensor is used to detect the position of the sampling container inside the sample outlet hood.

[0015] Furthermore, the sensor is a pressure sensor or a limit switch.

[0016] Furthermore, the sampling cover is made of a transparent material.

[0017] Furthermore, the vent is located on the same side of the sampling hood and above the sampling hood.

[0018] Furthermore, the maximum stroke of the drive mechanism is greater than the maximum distance between the sampling container and the top of the sampling cover directly below the connection point with the pipe.

[0019] Furthermore, the pump is a water pump, the drive mechanism is a hydraulic rod, a pneumatic rod, or an electric push rod, and the elastic element is a compression spring.

[0020] (III) Beneficial Effects

[0021] One of the above technical solutions has the following advantages or beneficial effects:

[0022] A circulating pipeline, equipped with a pump, pipes, and sampling mechanism, is formed on the reactor to extract the test liquid. This prevents the test liquid from remaining in the pipeline and affecting subsequent sampling. During sampling, a drive mechanism moves the sampling container into the circulating test liquid inside the sampling hood for quantitative sampling. After the sampling container is retracted into the sampling hood, the sampled liquid is automatically discharged through a limit plate and switch plate structure, preventing dangers such as over-sampling and valve malfunction. At the same time, the entire sampling and discharge process is carried out within the protective cover, which can reduce the mixing of impurities into the reactor and the sampled liquid, and prevent splashing liquid and other situations that may affect personnel safety, ensuring safe use, production quality, and the accuracy of sampling and testing.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0033] Example 1:

[0034] This utility model provides an automatic sampling mechanism for a silica reactor: its structure includes a reactor 1, a pump 2, a pipeline 3, and a sampling mechanism 4;

[0035] The reactor 1 is connected to the feed end of the pump 2 via a pipe 3;

[0036] The sampling mechanism 4 includes a drive mechanism 401, a sample outlet hood 402, a filter plate 403, a vent 404, a sampling hood 405, a sampling container 406, a sampling groove 407, a slide 408, a limiting plate 409, an elastic element 411, a sample outlet cover 412, a sample outlet 413, a sample outlet connector 414, a switch plate 415, a top plate 416, and a mechanical valve 419. The top of the sample outlet hood 402 is connected to the discharge end of the pump 2 via a pipe 3, and the bottom of the sample outlet hood 402 is connected to the reaction vessel 1 via a pipe 3. A sampling hood 405 is provided on the side end face of the sample outlet hood 402. The sample hood 405 is connected to the sample outlet 402. The bottom of the sample hood 405 is provided with a sample outlet connector 414 for communicating with the outside. The sample container 406 is disposed inside the sample hood 405 and the sample outlet 402. The driving mechanism 401 is assembled on the side of the sample outlet 402 away from the sample hood 405. The driving mechanism 401 is connected to one end of the sample container 406. The driving mechanism 401 is used to drive the sample container 406 to move inside the sample hood 405 and the sample outlet 402.

[0037] The sampling container 406 has a sampling groove 407 extending through the top. The bottom of the sampling container 406 has a sample outlet 413 communicating with the sampling groove 407. The bottom of the sampling groove 407 is an inclined surface that slopes downwards towards the sample outlet 413. The sampling container 406 also has a sliding groove 408, one end of which covers the sample outlet 413. A sample outlet cover 412 is slidably fitted into the sliding groove 408. A switch plate 415 is fixed to the bottom of the sample outlet cover 412 near the drive mechanism 401. The bottom of the switch plate 415 passes through the sample outlet 413 and is lower than the bottom of the sampling container 406. A limit plate is also fixed to the bottom of the sampling container 406 away from the drive mechanism 401. 409, An elastic element 411 is provided between the limiting plate 409 and the switch plate 415. The elastic element 411 is used to drive the sample outlet cover plate 412 to cover the sample outlet 413 through the switch plate 415. A top plate 416 is fixed inside the sample outlet cover 402. The top height of the top plate 416 is located between the bottom of the switch plate 415 and the bottom of the sampling container 406. The top plate 416 is located on the side of the switch plate 415 facing the drive mechanism 401. The top plate 416 is used to press the switch plate 415 to drive the sample outlet cover plate 412 to open the sample outlet 413 after the sampling container 406 enters the sample outlet cover 402 a certain distance. The bottom of the sample outlet cover 402 is an inclined surface that slopes down towards the sample outlet connector 414.

[0038] The sampling cover 405 is made of transparent material.

[0039] The vent 404 and the sampling cover 405 are located on the same side of the sample outlet cover 402 and above the sampling cover 405.

[0040] The maximum stroke of the drive mechanism 401 is greater than the maximum distance between the sampling container 406 and the top of the sample outlet cover 402 and the connection point of the pipe 3.

[0041] The pump 2 is a water pump, the drive mechanism 401 is a hydraulic rod, a pneumatic rod, or an electric push rod, and the elastic element 411 is a compression spring.

[0042] In use, the pump 2 continuously draws the test liquid from the reaction vessel 1, and forms a circulation pipeline for drawing the test liquid through the pipeline 3 and the sampling mechanism 4.

[0043] During sampling, the drive mechanism 401 moves the sampling container 406 to a position below the connection between the top of the sample outlet cover 402 and the pipe 3 to receive the test liquid. At this time, the switch plate 415, pressed by the elastic element 411, will cause the sample outlet cover 412 to seal the sample outlet 413 of the sampling container 406, allowing the sample tank 407 to receive the test liquid. After receiving the test liquid, the drive mechanism 401 can move the sampling container 406 back into the sample outlet cover 402. After the sampling container 406 enters the sample outlet cover 402, the sample outlet 413 will not open immediately. Only after retracting a certain distance will the top plate 416 contact the switch plate 415, restricting the switch plate 415 from continuing to move forward. The retraction direction movement causes the switch plate 415 to drive the sample outlet cover plate 412 to open the sample outlet 413. At this time, the liquid collected in the sampling tank 407 will flow out through the sample outlet 413 and the sample outlet connector 414. The user can connect a collection container or pipeline at the sample outlet connector 414 for receiving or transferring. Alternatively, a mechanical valve 419 can be added at the sample outlet connector 414 for control. After the sample is dispensed, the drive mechanism 401 can drive the sampling container 406 to extend a certain distance, so that the switch plate 415 is separated from the top plate 416 and puts it into standby mode. At this time, the switch plate 415 will continue to reset due to the elastic element 411, which will drive the sample outlet cover plate 412 to seal the sample outlet 413 of the sampling container 406.

[0044] The mechanism uses a circulating pipeline combined with a sampling container 406 for sampling, which can prevent dangers caused by over-sampling and valve malfunction. At the same time, the entire sampling and dispensing process is carried out within a protective cover, which can reduce the mixing of impurities into the reaction vessel and sampling liquid, prevent splashing liquid and other situations that may affect personnel safety, and prevent the residual liquid that does not participate in the reaction for a long time from remaining in the sampling pipeline when the traditional pump is used, which may affect the accuracy of subsequent sampling and testing, thus ensuring safe use, production quality and the accuracy of sampling and testing.

[0045] Meanwhile, the sampling hood 405 is made of transparent material, which makes it easy for users to judge the reaction status by observing the circulating liquid. The filter plate 403 and the air vent 404 are set so that when the sampling hood 402 and the sampling hood 405 are sealed, too much air will not be mixed in due to pressure. When the sample is being discharged, the pressure can be balanced, which facilitates automatic sample discharge and prevents sample discharge from being unsmooth.

[0046] Example 2:

[0047] Compared to Embodiment 1, the sampling mechanism 4 in this embodiment further includes a balance bar 410. One end of the balance bar 410 is fixed to the switch plate 415, and the other end of the balance bar 410 passes through the limiting plate 409, so that the switch plate 415 drives the sample cover plate 412 to slide more smoothly and prevent jamming. The rest of the structure and effect remain unchanged.

[0048] Example 3:

[0049] Compared to the previous embodiments, the sampling cover 405 in this embodiment includes an inlet 40501, a top cover 40502, a middle cover 40503, a bottom cover 40504, and an outlet 40505. The bottom cover 40504 is funnel-shaped and covers and fits over the bottom of the middle cover 40503. The top cover 40502 is embedded in the top of the middle cover 40503. The inlet 40501 is provided on the top cover 40502. The middle cover 40503 is provided at the bottom of the bottom cover 40504.

[0050] The connection between the middle cover 40503, the bottom cover 40504, and the top cover 40502 all adopt a staggered structure with an inner bottom and an outer height, which can prevent splashed liquids from seeping out of the sampling cover 405.

[0051] When in use, the sampling hood has a combined structure with only two external electrical control structures: the drive mechanism 401 and the pump 2. This makes it easier to maintain and prevents inconveniences such as repair, replacement, and cleaning. The rest of the structure and effect remain unchanged.

[0052] Example 4:

[0053] Compared to the previous embodiments, the sampling mechanism 4 in this embodiment further includes an electrically controlled valve 417 and a sensor 418. The electrically controlled valve 417 is electrically connected to the sensor 418. The electrically controlled valve 417 is mounted on the sample outlet connector 414. The sensor 418 is used to detect the position of the sampling container 406 inside the sample outlet cover 402.

[0054] The sensor 418 is a pressure sensor or a limit switch.

[0055] In use, the sensor 418 can be set to detect whether the sampling container 406 is in the sampling position. When the sampling container 406 is in the sampling position, the electric control valve 417 can be automatically opened by the signal from the sensor 418, which can realize automatic sampling and sampling. The rest of the structure and effect remain unchanged.
