Description

Technical Field

[0001] This utility model relates to the technical field of coal powder sampling equipment, specifically a coal powder sampling and receiving integrated device. Background Technology

[0002] In industrial production sectors such as thermal power generation and steel smelting, pulverized coal is an important fuel. Its particle size, moisture content, and other indicators directly affect combustion efficiency and production safety. Therefore, it is necessary to regularly sample and test the pulverized coal in the pulverized coal pipeline.

[0003] Currently, the mainstream method for coal dust sampling is still mainly manual operation: staff need to carry empty sampling bottles to the coal dust pipeline sampling point, manually open the sampling valve, align the sampling bottle with the sampling port to collect coal dust, and then transport the sampling bottle containing coal dust to the testing area after sampling. This process has obvious limitations: on the one hand, manually transporting the sampling bottles consumes a lot of manpower, especially when batch sampling is required (such as multiple sets of comparative experiments), and the back-and-forth transport will significantly increase working time and reduce sampling efficiency; on the other hand, the coal dust sampling environment is often accompanied by dust pollution, and some sampling points are located in harsh working conditions such as high temperature and high pressure. Staff are exposed to this environment for a long time, which not only results in high labor intensity but also poses health and safety hazards; in addition, manual operation makes it difficult to ensure the precise alignment of the sampling bottle and the sampling port each time, which may lead to coal dust leakage, affect the accuracy of the sample volume, and thus interfere with the subsequent test results. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an integrated coal powder sampling and receiving device to solve the technical problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal powder sampling and receiving integrated device, comprising a storage cabinet and a control cabinet. The storage cabinet has a storage cavity and a transfer cavity inside. Two sets of first storage racks and second storage racks are respectively installed in the storage cavity. A transverse slide is installed on the back of the first storage rack and the second storage rack. A push plate is connected to the output end of the transverse slide. A longitudinal slide is installed inside the transfer cavity. A transfer frame is connected to the output end of the longitudinal slide. A high-frequency reader and a planetary motor are installed in the middle of the transfer frame. A conveyor belt is connected to the four corners of the transfer frame through several rotating rollers. A limit frame is connected to the top of the transfer frame.

[0006] Furthermore, the push plate passes through the first storage rack and the second storage rack respectively, and the push plate is slidably connected to the first storage rack and the second storage rack respectively.

[0007] By adopting the above technical solution, the pusher plate can slide horizontally along the first storage rack (second storage rack) under the drive of the transverse slide table, directly acting on the sampling bottle in the first storage rack (second storage rack), and smoothly pushing it to the transfer rack (shifting one body position), avoiding the sampling bottle from tipping over due to the gap between the pusher plate and the storage rack, and ensuring the stability of the sampling bottle transfer.

[0008] Furthermore, both sets of the first and second storage racks are inclined and staggered.

[0009] By adopting the above technical solution, empty sampling bottles can slide from the first storage rack to the transfer rack, and full sampling bottles can slide from the transfer rack to the second storage rack without additional power, thus reducing transport resistance and equipment energy consumption. The staggered distribution can realize spatial partitioning of "empty bottle storage - transfer sampling - full bottle storage", avoiding mutual interference between empty bottles in the first storage rack and full bottles in the second storage rack. At the same time, it maximizes the use of the internal space of the storage cabinet, improves the single batch sampling capacity, and adapts to the sampling needs of multiple sets of comparative experiments.

[0010] Furthermore, a synchronous pulley is installed at the output end of the planetary motor and at one end of one of the rotating rollers, and the two synchronous pulleys are connected by a synchronous belt.

[0011] By adopting the above technical solution, the planetary motor can drive the rotating roller to rotate through the transmission structure of the synchronous pulley and synchronous belt, thereby driving the conveyor belt to run: when the planetary motor rotates forward, the conveyor belt drives the empty sampling bottle to move from the first storage rack to the inside of the transfer rack; when the planetary motor rotates in reverse, the conveyor belt drives the sampling bottle containing coal powder to move from the transfer rack to the second storage rack, realizing the power transmission of the sampling bottle "receive-rotate-send", and the synchronous belt drive has the characteristics of smooth transmission and low noise, which can prevent the sampling bottle from being displaced due to vibration during the transportation process.

[0012] Furthermore, the high-frequency reader, planetary motor, horizontal slide, and vertical slide are all electrically connected to the control cabinet.

[0013] By adopting the above technical solution, the control cabinet can achieve centralized automated control of each component: the staff only needs to preset the sampling parameters (such as the number of samplings and the amount of sampling per time) on the control panel inside the control cabinet, and the equipment can automatically complete actions such as pushing the horizontal slide, starting and stopping the planetary motor, and raising and lowering the vertical slide, without the need for real-time manual operation, reducing human intervention, while ensuring the synchronization and accuracy of the actions of each component, and avoiding sampling errors caused by delays in manual operation.

[0014] Furthermore, a sealing and correction assembly is connected to the top of the longitudinal slide table. The sealing and correction assembly includes a fixing plate. The bottom sides of the fixing plate are connected to mounting slides via guide rods. A guide tube is connected to the bottom of the fixing plate, and the upper part of the guide tube is flared.

[0015] By adopting the above technical solution, the trumpet-shaped structure inside the guide tube can guide the sampling bottle during the ascent process: if the sampling bottle is slightly offset due to transportation, the trumpet-shaped opening can automatically correct it to the position of the guide tube axis, ensuring that the sampling bottle is accurately aligned with the subsequent sampling mechanism; at the same time, the sealing and correction component can fit against the top of the sampling bottle during sampling, reducing the leakage of coal powder from the gap between the sampling port and the sampling bottle, ensuring accurate sampling volume, and avoiding dust contamination of the internal components of the transfer chamber.

[0016] Furthermore, a sampling port is provided on one side of the top of the storage cabinet, and the sampling port, the guide tube, and the high-frequency reader are located on the same axis.

[0017] By adopting the above technical solution, the coaxial structure can ensure that the bottle mouth of the sampling bottle can be accurately aligned with the sampling port after the guide tube is corrected. At the same time, the high-frequency reader can be directly aligned with the information code (such as QR code or RFID tag) on ​​the bottom of the sampling bottle to quickly complete the reading and recording of the identification information of the sampling bottle, providing a basis for subsequent sampling data and corresponding traceability of the sampling bottle, and avoiding confusion between sampling bottles from different batches.

[0018] Furthermore, a photoelectric sensor is installed at the bottom of the sampling port, and the photoelectric sensor is electrically connected to the control cabinet.

[0019] By adopting the above technical solution, the photoelectric sensor can detect the position of the sampling bottle in real time: when the longitudinal slide moves the sampling bottle on the transfer frame to below the sampling port, the photoelectric sensor triggers a signal and transmits it to the control cabinet. The control cabinet immediately controls the longitudinal slide to stop running, ensuring that the sampling bottle rises to the same height each time, avoiding damage caused by the bottle mouth colliding with the sampling port due to the sampling bottle being too high, or coal powder leakage caused by the sampling bottle being too low.

[0020] Furthermore, the limiting frame is U-shaped, and the inlet of the limiting frame extends outward in an inverted V-shape.

[0021] By adopting the above technical solution, the "U"-shaped structure can limit the sampling bottle from both sides and the rear end, preventing the sampling bottle from shifting left or right or sliding forward or backward during the operation of the conveyor belt or the lifting and lowering of the transfer frame; while the inverted V-shaped inlet can guide the sampling bottle when it enters the transfer frame from the first storage rack. Even if there is a slight positional deviation of the sampling bottle, it can slide into the limiting frame through the guide of the inverted V-shaped opening, ensuring that the sampling bottle accurately enters the center position of the conveyor belt.

[0022] Furthermore, the storage cabinet has an observation window on one side, and the observation window is made of transparent glass.

[0023] By adopting the above technical solution, staff can observe the storage status of sampling bottles inside the storage cabinet (such as the remaining number of empty bottles on the first storage rack and the number of full bottles on the second storage rack) and the transfer process in real time through a transparent observation window. They can monitor the equipment operation without opening the storage cabinet, which is convenient for timely replenishment of empty bottles or cleaning of full bottles, and can also avoid frequent opening of the cabinet door, which would cause dust to spill out and maintain the cleanliness of the sampling environment.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model achieves fully automated flow of sampling bottles from "empty bottle storage - transfer to sampling port - full bottle storage" by setting up an automated transfer structure (transverse slide, longitudinal slide, planetary motor and conveyor belt). There is no need for manual handling of sampling bottles, which greatly reduces manpower consumption and avoids staff being exposed to harsh sampling environments, thus reducing health and safety risks.

[0026] 2. This utility model utilizes the cooperation of an inclined storage rack, a limiting frame, and a guide tube to achieve automatic filling and returning of the sampling bottle by gravity. Combined with the correction of the guide tube and the positioning of the photoelectric sensor, it ensures the precise alignment of the sampling bottle and the sampling port, reduces coal powder leakage, ensures accurate sampling volume, improves batch sampling efficiency, and saves round-trip transportation time.

[0027] 3. This utility model, through the linkage between the high-frequency reader and the control cabinet, can automatically record the identity information and sampling process of each sampling bottle, which facilitates the traceability and management of subsequent sampling data, avoids confusion between sampling bottles from different batches, and improves the standardization of sampling and testing.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1: A coal powder sampling and receiving integrated device, such as... Figures 1-5 As shown, the system includes a storage cabinet 1 and a control cabinet 19. The storage cabinet 1 has a storage cavity 101 and a transfer cavity 102. Two sets of first storage racks 2 and second storage racks 3 are installed in the storage cavity 101. A transverse slide 4 is installed on the back of the first storage rack 2 and the second storage rack 3. A push plate 5 is connected to the output end of the transverse slide 4. A longitudinal slide 6 is installed inside the transfer cavity 102. A transfer frame 7 is connected to the output end of the longitudinal slide 6. A high-frequency reader / writer 8 and a planetary motor 9 are installed in the middle of the transfer frame 7. Several rollers 10 connect the four corners of the transfer frame 7 to conveyor belts. The conveyor belt 11 and the top of the transfer frame 7 are connected to the limiting frame 12. The push plate 5 passes through the first storage rack 2 and the second storage rack 3 respectively, and the push plate 5 is slidably connected to the first storage rack 2 and the second storage rack 3 respectively. The push plate 5 can slide horizontally along the first storage rack 2 (second storage rack 3) under the drive of the transverse slide table 4, and directly act on the sampling bottle in the first storage rack 2 (second storage rack 3), and push it smoothly to the transfer frame 7 (translate one body position), so as to avoid the sampling bottle tipping over due to the gap between the push plate 5 and the storage rack, and ensure the stability of the sampling bottle transfer.

[0037] See Figure 2 and Figure 3In the above embodiment, both sets of first storage racks 2 and second storage racks 3 are inclined and staggered. When empty sampling bottles slide from the first storage rack 2 to the transfer rack 7 and full sampling bottles slide from the transfer rack 7 to the second storage rack 3, the conveying resistance can be reduced without additional power, thus reducing equipment energy consumption. The staggered distribution can realize the spatial partitioning of "empty bottle storage - transfer sampling - full bottle storage", avoiding mutual interference between empty bottles in the first storage rack 2 and full bottles in the second storage rack 3. At the same time, it maximizes the use of the internal space of the storage cabinet 1, improves the single batch sampling capacity, and adapts to the sampling needs of multiple sets of comparative experiments.

[0038] See Figure 5 In the above embodiment, a synchronous pulley 14 is installed at the output end of the planetary motor 9 and one end of one of the rotating rollers 10, and the two synchronous pulleys 14 are connected by a synchronous belt 15. The planetary motor 9 can drive the rotating roller 10 to rotate through the transmission structure of the synchronous pulley 14 and the synchronous belt 15, thereby driving the conveyor belt 11 to run: when the planetary motor 9 rotates forward, the conveyor belt 11 drives the empty sampling bottle to move from the first storage rack 2 to the inside of the transfer rack 7; when the planetary motor 9 rotates in reverse, the conveyor belt 11 drives the sampling bottle containing coal powder to move from the transfer rack 7 to the second storage rack 3, realizing the power transmission of the sampling bottle "receive-rotate-send", and the synchronous belt 15 transmission has the characteristics of smooth transmission and low noise, which can prevent the sampling bottle from being displaced due to vibration during the transportation process.

[0039] See Figures 1-5 In the above embodiments, the high-frequency reader 8, planetary motor 9, horizontal slide 4 and vertical slide 6 are all electrically connected to the control cabinet 19. The control cabinet 19 can realize centralized automated control of each component: the operator only needs to preset the sampling parameters (such as the number of samplings and the amount of sampling per time) on the control panel inside the control cabinet 19, and the equipment can automatically complete the actions such as pushing the horizontal slide 4, starting and stopping the planetary motor 9, and raising and lowering the vertical slide 6 without the need for real-time manual operation, reducing human intervention, and ensuring the synchronization and accuracy of the actions of each component, avoiding sampling errors caused by delays in manual operation.

[0040] See Figure 2 and Figure 3In the above embodiment, a sealing and correction assembly 16 is connected to the top of the longitudinal slide table 6. The sealing and correction assembly 16 includes a fixing plate 1601. The bottom sides of the fixing plate 1601 are connected to mounting slide plates 1604 via guide rods 1602. A guide tube 1603 is connected to the bottom of the fixing plate 1601. The upper part of the guide tube 1603 is funnel-shaped. The funnel-shaped structure inside the guide tube 1603 can guide the sampling bottle during the rising process. If the sampling bottle is slightly offset due to transportation, the funnel-shaped opening can automatically correct it to the axis position of the guide tube 1603, ensuring that the sampling bottle is accurately aligned with the subsequent sampling mechanism. At the same time, the sealing and correction assembly 16 can fit against the top of the sampling bottle during sampling, reducing the leakage of coal powder from the gap between the sampling port 13 and the sampling bottle, ensuring accurate sampling volume, and avoiding dust contamination of the internal components of the transfer chamber 102.

[0041] See Figures 1-3 In the above embodiment, a sampling port 13 is provided on one side of the top of the storage cabinet 1, and the sampling port 13, the guide tube 1603 and the high-frequency reader 8 are located on the same axis. The coaxial structure can ensure that after the sampling bottle is corrected by the guide tube 1603, its mouth can be accurately aligned with the sampling port 13. At the same time, the high-frequency reader 8 can be directly aligned with the information code at the bottom of the sampling bottle to quickly complete the reading and recording of the identification information of the sampling bottle, providing a basis for subsequent sampling data and corresponding traceability of the sampling bottle, and avoiding confusion between sampling bottles from different batches.

[0042] See Figure 2 In the above embodiment, a photoelectric sensor 17 is installed at the bottom of the sampling port 13 and is electrically connected to the control cabinet 19. The photoelectric sensor 17 can detect the position of the sampling bottle in real time: when the longitudinal slide 6 drives the sampling bottle on the transfer frame 7 to rise below the sampling port 13, the photoelectric sensor 17 triggers a signal and transmits it to the control cabinet 19. The control cabinet 19 immediately controls the longitudinal slide 6 to stop running, ensuring that the sampling bottle rises to the same height each time, avoiding damage caused by the bottle mouth colliding with the sampling port 13 due to the sampling bottle being too high, or coal powder leakage caused by the sampling bottle being too low.

[0043] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In the above embodiment, the limiting frame 12 is U-shaped, and the inlet of the limiting frame 12 extends outward in an inverted V-shape. The U-shaped structure can limit the sampling bottle from both sides and the rear end to prevent the sampling bottle from shifting left or right or sliding forward or backward during the operation of the conveyor belt 11 or the lifting and lowering of the transfer frame 7. The inverted V-shaped inlet can guide the sampling bottle when it enters the transfer frame 7 from the first storage rack 2. Even if there is a slight positional deviation of the sampling bottle, it can slide into the limiting frame 12 through the guide of the inverted V-shaped opening to ensure that the sampling bottle accurately enters the center position of the conveyor belt 11.

[0044] Example 2: To facilitate real-time monitoring of the sampling bottle storage status by staff, Example 2 is an improvement upon Example 1. (See attached document for details.) Figure 1 The storage cabinet 1 has an observation window 18 on one side, and the observation window 18 is made of transparent glass. Staff can observe the storage status of the sampling bottles inside the storage cabinet 1 in real time (such as the remaining number of empty bottles in the first storage rack 2 and the number of full bottles in the second storage rack 3) and the transfer process through the transparent observation window 18. The equipment operation status can be grasped without opening the storage cabinet 1. This is convenient for timely replenishment of empty bottles or cleaning of full bottles, and can also avoid frequent opening of the cabinet door, which may cause dust to spill out and maintain the cleanliness of the sampling environment.

[0045] The implementation principle of this utility model is as follows: First, the operator places several empty sampling bottles labeled with information codes (such as QR codes or RFID tags) into two sets of first storage racks 2. Then, the operator presets sampling parameters (such as the number of samplings and the amount of sample taken per time) on the control panel inside the control cabinet 19 to complete the preparation work. After starting the equipment, the control panel inside the control cabinet 19 first controls the output end of the longitudinal slide 6 to rise, driving the transfer rack 7 to move to a position flush with the outlet end of one set of first storage racks 2, at which point the longitudinal slide 6 stops. Next, the control cabinet 19 activates the transverse slide 4 on the back of the first storage rack 2. The output end of the transverse slide 4 pushes the push plate 5 to slide along the first storage rack 2, and the push plate 5 pushes the empty sampling bottles on the first storage rack 2 towards the transfer chamber 102. Simultaneously, the control cabinet 19 activates the planetary motor... When the machine 9 rotates forward, the planetary motor 9 drives the rotating roller 10 to rotate via the synchronous pulley 14 and synchronous belt 15. The rotating roller 10 drives the conveyor belt 11 to run. Under the combined action of the pushing force of the pusher plate 5 and the friction force of the conveyor belt 11, the empty sampling bottle slides along the first storage rack 2 onto the conveyor belt 11 of the transfer rack 7. The limiting frame 12 at the top of the transfer rack 7 limits the sampling bottle to the left and right to prevent it from shifting or misaligning. When the sampling bottle is completely inside the transfer rack 7, the high-frequency reader 8 in the middle of the transfer rack 7 reads the information code at the bottom of the sampling bottle and transmits the information to the control cabinet 19 for recording. After receiving the information, the control cabinet 19 immediately shuts down the planetary motor 9 and simultaneously controls the output end of the transverse slide 4 to reset, driving the pusher plate 5 to rotate. Plate 5 returns to its initial position; the remaining empty sampling bottles in the first storage rack 2 automatically move down along the inclined surface following the push plate 5 under the action of gravity, waiting for the next transfer; then the control cabinet 19 starts the longitudinal slide 6, driving the transfer frame 7 and the sampling bottles to rise synchronously. When the top of the sampling bottle contacts the guide tube 1603 of the sealing correction component 16, the horn-shaped structure inside the guide tube 1603 slightly corrects the sampling bottle, ensuring that the axis of the sampling bottle coincides with the axis of the sampling port 13; when the photoelectric sensor 17 at the bottom of the sampling port 13 detects the sampling bottle, it immediately sends a signal to the control cabinet 19, and the control cabinet 19 controls the longitudinal slide 6 to stop running and maintain the current height; at this time, the control cabinet 19 controls When the external sampling mechanism is activated, the sampling tube of the sampling mechanism extends from the sampling port 13 and is inserted into the sampling bottle, injecting coal powder into the sampling bottle until the preset sampling amount is reached. The sampling mechanism then stops working and retracts the sampling tube. After sampling is completed, the control cabinet 19 starts the longitudinal slide 6 again, driving the transfer frame 7 and the sampling bottle containing coal powder to move down synchronously until the transfer frame 7 is flush with the inlet end of one of the second storage racks 3. The longitudinal slide 6 then stops. The control cabinet 19 starts the planetary motor 9 to reverse. The planetary motor 9 drives the rotating roller 10 to rotate in the opposite direction through the synchronous wheel 14 and the synchronous belt 15, thereby driving the conveyor belt 11 to run in the opposite direction. The conveyor belt 11 pushes the sampling bottle containing coal powder toward the second storage rack 3.Under the thrust of the conveyor belt 11, the sampling bottle slides into the inclined second storage rack 3 and contacts the push plate 5 inside the rack. After a delay, the transverse slide 4 is activated, sliding along the second storage rack 3 one sampling bottle length under the combined action of the push plate 5 and gravity. This completes one coal powder sampling process. The equipment will repeat the above steps, sequentially transferring, sampling, and storing empty sampling bottles in the first storage rack 2 until all empty bottles have been sampled. Staff can monitor the sampling progress through the observation window 18 on one side of the storage cabinet 1. Once all samples are collected, the cabinet door of storage cabinet 1 is opened, and the full bottles in the second storage rack 3 are removed and sent to the testing area.
