Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling device technology, and more specifically, to a sampling device for cement production. Background Technology
[0002] Sampling devices for cement production are key equipment for ensuring the quality of cement products. They are mainly used to collect representative samples during cement production to provide a basis for quality inspection and production control. They are mainly used in closed or semi-closed containers such as silos, tanks, and pipelines. By inserting the device into the material, deep samples are collected, which makes up for the limitations of surface sampling and ensures that the sample can reflect the overall uniformity of the material. They are usually composed of hollow metal tubes, mostly made of wear-resistant steel or stainless steel, which are resistant to dust abrasion and corrosion, handles, valves, etc. Some tubes have beveled cuts or multi-hole designs at the head to reduce resistance and collect materials evenly during insertion. Since the sampling depth of cement raw materials varies, it is necessary to perform sampling adjustment operations.
[0003] In related technologies, during the use of sampling devices, workers typically insert a sampling tube into the inner wall of the cement to be sampled, allowing the cement to enter the tube. The cement is then extracted by drawing out the tube, thus performing the cement sampling operation.
[0004] However, in the current use of sampling devices, the sampling tubes are generally hollow tubes of fixed length, while the sampling requirements for cement vary according to actual needs. This makes it difficult for the sampling tubes to perform sampling operations at different depths, affecting the sampling flexibility and adaptability of the sampling device. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Reference Figures 1-4 This utility model provides a technical solution: a sampling device for cement production, including a sampling cylinder 1 and a sampling adjustment mechanism. A sampling port 2 is provided on the front side of the sampling cylinder 1. A closed disc 3 is movably connected inside the sampling cylinder 1, which can form a medium at the top of the sampling cylinder 1 that can be raised and lowered to adjust the sampling insertion depth of the sampling cylinder 1. This allows the user to adjust the subsequent insertion sampling depth of the sampling cylinder 1 according to the actual sampling depth requirements, avoiding the situation where it is difficult to adjust the sampling depth when using the sampling cylinder 1. Therefore, the sampling flexibility and adaptability of the sampling cylinder 1 are improved.
[0021] Reference Figures 1-4 In a preferred embodiment, the sampling adjustment mechanism includes an adjustment cylinder 4, which is movably connected to the top of the sampling cylinder 1. An adjustment rod 5 is fixedly connected to the top of the sampling cylinder 1 and located inside the adjustment cylinder 4. Scale strips 6 are respectively embedded and connected to the left sides of the adjustment cylinder 4 and the adjustment rod 5. A reference plate 7 is fitted onto the surface of the adjustment cylinder 4. An adjustment opening and closing mechanism is located inside the adjustment rod 5 and the adjustment cylinder 4. According to the actual depth requirements of the external cement material, the adjustment cylinder 4 is moved upwards by hand. At this time, the adjustment rod 5 moves inside the adjustment cylinder 4, adjusting the connection between the sampling cylinder 1 and the adjustment cylinder 4. Simultaneously, the values on the scale strips 6 on the left sides of the adjustment cylinder 4 and the adjustment rod 5 are added together to obtain the subsequent sampling insertion depth of the sampling head. Subsequently, the adjustment cylinder 4 is held in conjunction with the adjustment rod 5 to drive the sampling cylinder 1 into the external cement. This allows for sampling of cement at the target depth. At this point, the bottom of the reference plate 7 should contact the top of the cement material to ensure the sampling tube 1 is inserted correctly. The opening and closing mechanism includes an opening and closing cavity 8, an opening and closing cylinder 9, and an opening and closing column 10. The opening and closing cavity 8 is located inside the adjusting rod 5 and the adjusting cylinder 4. The opening and closing cylinder 9 is movably connected inside the opening and closing cavity 8. The opening and closing column 10 is movably connected inside the opening and closing cylinder 9. The bottom of the opening and closing column 10 passes through the sampling tube 1 and is fixedly connected to the top of the closing plate 3. This allows the adjusting cylinder 4 to move up and down with the adjusting cylinder 4, providing a medium for the user to lift and move the closing plate 3. This allows the user to lift the closing plate 3 to open and close the sampling port 2, avoiding situations where the closing plate 3 is difficult to lift and open, thus improving the ease of opening and closing the closing plate 3.
[0022] Reference Figures 2-4 In a preferred embodiment, magnetic strips 11 are embedded and connected to both sides of the inner wall of the opening and closing cylinder 9, and a magnetic cylinder 12 connected to the magnetic strips 11 is embedded and connected to the top of the surface of the opening and closing column 10. This allows for magnetic connection and positioning between the opening and closing cylinder 9 and the opening and closing column 10, preventing the opening and closing cylinder 9 from being difficult to lift the closed disc 3 through the opening and closing column 10 during use. This improves the connection effect between the opening and closing column 10 and the opening and closing cylinder 9. A support strip 13 is fixedly connected to the inner wall of the sampling cylinder 1 at the bottom of the sampling port 2. The bottom of the closed disc 3 contacts the top of the support strip 13, which can provide stable support between the closed disc 3 and the sampling cylinder 1 during operation, preventing the closed disc 3 from being unstable during use. This improves the working stability of the closed disc 3.
[0023] Reference Figures 2-3In a preferred embodiment, a clamping port 14 is provided at the bottom right side of the adjusting cylinder 4, and a clamping plate 15 is movably connected inside the clamping port 14. This allows for clamping and positioning of the adjusting rod 5 and the adjusting cylinder 4, preventing the adjusting rod 5 from being difficult to position with the adjusting cylinder 4 during use. This improves the ease of fixing the adjusting rod 5 and the adjusting cylinder 4. A screw cylinder 16, which communicates with the clamping port 14, is fixedly connected to the bottom right side of the adjusting cylinder 4. A stud 17, which is fixedly connected to the clamping plate 15, is threaded inside the screw cylinder 16. This provides a medium for applying clamping force to the clamping plate 15, preventing the clamping plate 15 from being difficult to apply clamping force during use. This improves the clamping force application effect of the clamping plate 15.
[0024] Reference Figures 2-3 In a preferred embodiment, a screw hole 18 is provided on the right side of the reference plate 7, and a screw 19 is threaded inside the screw hole 18. This allows for the clamping and fixing of the reference plate 7 and the adjusting cylinder 4, preventing the reference plate 7 from being difficult to position during use. This improves the stability of the reference plate 7. Rubber discs 20 are fixedly connected to the left sides of both the clamping disc 15 and the screw 19. The rubber discs 20 contact the surfaces of the adjusting cylinder 4 and the adjusting rod 5, respectively, and can clamp and prevent slippage between the screw 19 and the clamping disc 15. This improves the stability of the force applied by the screw 19 and the clamping disc 15.
[0025] Specifically, the working process or principle of this sampling device for cement production is as follows: During use, based on the actual sampling depth requirements of the external cement material, the hand-held adjusting cylinder 4 is moved upwards. At this time, the adjusting rod 5 moves inside the adjusting cylinder 4, adjusting the connection between the sampling cylinder 1 and the adjusting cylinder 4. Simultaneously, the value of the adjusting rod 5 protruding from the scale 6 and the value of the scale 6 on the left side of the adjusting cylinder 4 located at the bottom of the reference plate 7 are read. Adding these two values yields the subsequent insertion sampling depth of the sampling cylinder 1. After the adjusting cylinder 4 is adjusted upwards, the hand-held stud 17 is rotated to apply a threaded thrust to the leftward movement of the clamping plate 15, causing the clamping plate 15 to drive the rubber disc 20 to the leftward. The moving and adjusting rod 5 contacts and abuts against each other, securing the adjusting cylinder 4 and adjusting rod 5 together. During this process, as the adjusting cylinder 4 rises, the convex ball at the top of the opening and closing cylinder 9 contacts and abuts against the top of the adjusting cylinder 4, moving upwards with the adjusting cylinder 4. At this time, the opening and closing cylinder 9, through the opening and closing column 10, in conjunction with the magnetic strip 11 and magnetic cylinder 12, drives the closing disk 3 to move upwards, so that the top of the closing disk 3 contacts and abuts against the top of the inner wall of the sampling cylinder 1. At this time, the opening and closing column 10, affected by the resistance of the closing disk 3 and the sampling cylinder 1, moves inside the opening and closing cylinder 9, extending the length of the sampling cylinder 1. Simultaneously, the magnetic cylinder 12, in conjunction with the magnetic strip 11, facilitates the movement of the extended opening and closing cylinder 9 and the opening and closing column 10. The magnetic positioning process prepares the opening and closing cylinder 9 for lifting the closing disc 3 in conjunction with the opening and closing column 10. It is important to note that after the opening and closing column 10 moves with the adjusting cylinder 4, it should be held and moved upwards a short distance to provide downward movement allowance for the closing disc 3. This allows the closing disc 3 to move downwards and contact the support bar 13, closing the sampling port 2. Subsequently, the adjusting cylinder 4, in conjunction with the adjusting rod 5, moves the sampling cylinder 1 to insert into the external cement material. At this time, the screw 19, in conjunction with the screw hole 18 and the rubber disc 20, provides threaded clamping and stabilization between the reference plate 7 and the adjusting cylinder 4, allowing the reference plate 7 to move with the adjusting cylinder 4. When the bottom of the reference plate 7 contacts the external cement material... After the top of the material contacts the sample, ensure that the sampling tube 1 is inserted to the target sampling depth. At this time, hold the opening and closing tube 9 and cooperate with the opening and closing column 10 to apply an upward lifting force to the closed plate 3 through the magnetic tube 12 and magnetic strip 11, so that the closed plate 3 is misaligned with the sampling port 2, opening the sampling port 2, allowing the external cement material to enter the sampling tube 1 through the sampling port 2. At this time, the sampling tube 1 can be shaken by adjusting the tube 4 and adjusting the rod 5 to speed up the entry of external cement into the sampling tube 1. Then, release the opening and closing tube 9 and the closed plate 3 will fall and contact the support bar 13 under the influence of gravity, closing the sampling port 2. Then hold the adjusting tube 4 and adjust the rod 5 to move the sampling tube 1 to move out the cement material, thus completing the cement sampling operation.
