Description

Technical Field

[0001] This application relates to the field of material sampling, and in particular to a sampling device for a high-belite cement grinding aid mixing tank. Background Technology

[0002] In the cement production industry, quality control of various cement products is crucial. As a type of cement with special properties, the quality of grinding aids directly affects the production efficiency and quality of high-belite cement. During the production process of high-belite cement grinding aids, it is necessary to sample and test the materials inside the mixing tank to ensure that the various indicators of the grinding aid meet the requirements. With the continuous development of the cement industry, the quality requirements for high-belite cement grinding aids are becoming increasingly stringent, correspondingly placing higher demands on the performance and reliability of the mixing tank sampling device. A good sampling device can obtain samples of the materials inside the mixing tank in a timely and accurate manner, providing reliable data support for quality testing, thereby ensuring the production quality of high-belite cement.

[0003] In the past, the common method for sampling materials inside the high-belite cement grinding aid mixing tank was to open a regular valve installed on the side of the tank to allow the material to flow out for sampling. However, opening the valve connected the mixing tank to the outside environment, and the entry of outside air could contaminate the materials inside the tank. Utility Model Content

[0004] To ensure that the mixing vessel remains sealed during the sampling process, this application provides a sampling device for a mixing vessel containing high-belite cement grinding aid.

[0005] The sampling device for a high-belite cement grinding aid mixing tank provided in this application adopts the following technical solution:

[0006] A sampling device for a high-Belit cement grinding aid mixing vessel includes a vessel body, with a sampling tube connected to one side of the vessel body. The sampling tube includes a first sampling tube and a second sampling tube that are interconnected. A first valve is installed on the first sampling tube, and a piston block is slidably connected inside the second sampling tube. A second valve is installed at the end of the second sampling tube away from the first sampling tube. An installation cavity is provided between the piston block and the second valve. The diameter of the installation cavity is larger than the inner diameter of the second sampling tube and the diameter of the piston block. An adjustment mechanism is connected to the second sampling tube to drive the piston block to move closer to or further away from the installation cavity.

[0007] By adopting the above technical solution, during sampling, valves one and two are initially kept open. The adjusting mechanism moves the piston block closer to the mounting cavity. When the piston block is close to the mounting cavity, valve one is closed, and the adjusting mechanism continues to move the piston block into the mounting cavity. Since the diameter of the mounting cavity is larger than the diameter of the piston block, the material between the piston block and valve one can flow through the mounting cavity and into the sampling tube near valve two. Simultaneously, valve one is opened, allowing the material in the sampling tube to flow out, completing the sampling. Subsequently, the adjusting mechanism moves the piston block away from valve two. When the piston block disengages from the mounting cavity and is tightly engaged in the sampling tube, valve one is opened to facilitate the piston block's reset. After the piston block resets, both valves one and two are closed. This ensures that the mixing vessel remains sealed during the sampling process.

[0008] Preferably, the adjustment mechanism includes a threaded rod that is threadedly connected to one end of the sampling tube away from the installation cavity, one end of the threaded rod extending out of the sampling tube, and the other end being rotatably connected to the piston block.

[0009] By adopting the above technical solution, rotating the threaded rod can easily drive the piston block to slide inside the sampling tube, achieving flexible control and making the operation relatively simple.

[0010] Preferably, a rubber block is threadedly connected to the threaded rod, and the rubber block is fixedly connected to the second sampling tube and closely attached to the connection between the second sampling tube and the threaded rod.

[0011] By adopting the above technical solution, the rubber block can restrict external dust and impurities from entering the connection between the sampling tube and the threaded rod, reducing the occurrence of dust and impurities affecting the normal use of the threaded rod, and also playing a certain sealing role, reducing the possibility of sample leakage.

[0012] Preferably, the piston block is an elastic block.

[0013] By adopting the above technical solution, the elastic piston block can better adapt to the internal structure of the sampling tube, ensuring that the piston block fits tightly against the inner wall of the sampling tube and reducing material leakage.

[0014] Preferably, a protective cover is fixedly connected to the outside of the sampling tube, and the protective cover covers the threaded rod and the rubber block inside.

[0015] By adopting the above technical solution, a protective cover is set on the outside of the sampling tube, and the threaded rod and rubber block are covered inside, which can protect the two and reduce the occurrence of damage to the threaded rod and rubber block due to external factors.

[0016] Preferably, one side of the protective cover has a doorway, and a door body is hinged at the doorway to block the doorway.

[0017] By adopting the above technical solution, it is easy to open and close the door, thereby allowing operation and maintenance of the threaded rod inside the protective cover.

[0018] Preferably, a mounting ring is fixedly connected to one side of the door body, and a second mounting ring is fixedly connected to one side of the protective cover. A locking rod is inserted into both the first and second mounting rings, and the upper end of the locking rod is bent to one side.

[0019] By adopting the above technical solution, the door can be effectively secured, restricting its arbitrary opening and improving the protection and safety of the internal components of the protective cover. Furthermore, unlocking the door is simple; it only requires pulling the locking lever to disengage the first and second mounting rings.

[0020] Preferably, a flange is fixedly connected to one end of the sampling tube near the vessel body, a sampling port is provided on one side of the vessel body, and one end of the sampling tube is connected to the sampling port and is fastened to the vessel body through the flange.

[0021] By adopting the above technical solution, the sampling tube can be stably connected to the vessel body, ensuring the sealing between the sampling tube and the vessel body, which is conducive to the smooth completion of the sampling operation, and at the same time, it is convenient to disassemble and repair the sampling tube.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The mixing vessel was kept sealed during the sampling process;

[0024] 2. It achieves flexible control and is relatively easy to operate;

[0025] 3. A protective cover is installed on the outside of the sampling tube to protect the threaded rod and rubber block. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses a sampling device for a high-belite cement grinding aid mixing tank. (Refer to...) Figure 1 and Figure 2 The sampling device includes a vessel body 1 and a sampling tube 2 connected to one side of the vessel body 1. The sampling tube 2 is connected to the vessel body 1 to achieve material sampling. The sampling tube 2 includes a first sampling tube 21 and a second sampling tube 22 that are connected to each other. The first sampling tube 21 is arranged horizontally, and one end of the first sampling tube 21 is connected to the vessel body 1. The second sampling tube 22 is arranged vertically, and the upper end of the second sampling tube 22 is fixed and connected to the end of the first sampling tube 21 that is away from the vessel body 1.

[0032] A valve 211 is installed on the first sampling tube 21, which controls the flow of material inside the first sampling tube 21. A piston block 3 is vertically slidably connected inside the second sampling tube 22. The piston block 3 is an elastic block, and its outer wall is tightly fitted to the inner wall of the second sampling tube 22, allowing it to slide back and forth within the tube. An adjustment mechanism 4 is connected to the second sampling tube 22 to adjust the vertical movement of the piston block 3.

[0033] A valve 221 is installed at the lower end of the sampling tube 22. The valve 221 is used to control the connection between the sampling tube 22 and the outside. An installation cavity 23 is provided between the piston block 3 and the valve 221. The diameter of the installation cavity 23 is larger than the inner diameter of the sampling tube 22 and the diameter of the piston block 3.

[0034] Reference Figure 1 and Figure 2 A flange 24 is fixedly connected to one end of the sampling tube 2 near the vessel body 1. A sampling port is provided on the side wall of the vessel body 1. One end of the sampling tube 21 is connected to the sampling port. The flange 24 is fastened to the vessel body 1 with screws. The flange 24 connection method has the advantages of strong connection and good sealing performance, which can ensure that the material will not leak during the process of flowing from the vessel body 1 into the sampling tube 2.

[0035] The adjustment mechanism 4 includes a threaded rod 41 that is threaded to the upper end of the sampling tube 22. The upper end of the threaded rod 41 extends out of the sampling tube 22 and is fixedly connected to a cap 42. The lower end of the threaded rod 41 is rotatably connected to the piston block 3.

[0036] When the threaded rod 41 is rotated, the threaded rod 41 will move along the axial direction, thereby driving the piston block 3 to slide inside the sampling tube 22.

[0037] A rubber block 43 is threaded through and connected to the threaded rod 41. The rubber block 43 is located outside the sampling tube 2 and fixedly connected to the sampling tube 22. The rubber block 43 is in close contact with the connection between the sampling tube 22 and the threaded rod 41. The rubber block 43 serves to seal and prevent loosening, limiting material leakage from the connection between the threaded rod 41 and the sampling tube 22, and reducing the occurrence of loosening of the threaded rod 41.

[0038] Reference Figure 2 and Figure 3 A protective cover 5 is fixedly connected to the outside of the sampling tube 2. The protective cover 5 is located at the upper end of the sampling tube 22 and covers the threaded rod 41 and the rubber block 43 inside.

[0039] A doorway 51 is provided on one side of the protective cover 5, and a door body 6 is hinged to the doorway 51 to block it. The door body 6 facilitates the maintenance and repair of the threaded rod 41 and the rubber block 43, and also makes it easy to open the door body 6 to operate the threaded rod 41 for rotation.

[0040] A mounting ring 61 is fixedly connected to one end of the door body 6 away from the hinge joint between the door body 6 and the protective cover 5. A mounting ring 52 is fixedly connected to one side of the protective cover 5. When the door body 6 is closed, the mounting ring 61 overlaps the upper surface of the mounting ring 52. A locking rod 7 is inserted into both the mounting ring 61 and the mounting ring 52. The upper end of the locking rod 7 is bent to one side. The locking rod 7 is used to lock the door body 6 in the closed state, preventing the door body 6 from being opened accidentally. The bent design makes the locking rod 7 less likely to fall off, enhancing the reliability of the lock.

[0041] The implementation principle of the sampling device for a high-belite cement grinding aid mixing tank according to an embodiment of this application is as follows: When it is necessary to take out a sample, valve 211 and valve 221 can be opened. The piston block 3 is driven to move downward by the adjusting mechanism 4. At this time, the material in the tank body 1 enters the sampling tube 2. When the piston block 3 is close to the upper end of the mounting cavity 23, valve 211 is closed. The piston block 3 is then adjusted to move downward and enter the mounting cavity 23. At this time, the sampling tube 22 is connected to the outside. The material moves through the mounting cavity 23 from the upper end of the piston block 3 and exits the sampling tube 2 from the lower end of the sampling tube 22, thus completing the material sampling.

[0042] Similarly, during reset, adjust the piston block 3 to move upward until the piston block 3 is engaged in the upper end of the mounting cavity 23. At this time, the upper and lower ends of the piston block 3 are not connected. Then open valve 1 211, adjust the piston block 3 to continue moving upward to reset, and finally close valve 1 211 and valve 2 221.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
