Description

Technical Field

[0001] This utility model relates to the field of cleaning agent production and processing technology, and in particular to a sampling device for cleaning agent production and processing. Background Technology

[0002] Cleaning agents are chemical reagents used to clean objects, and their production and processing are usually completed in a reaction vessel through mixing or reaction. After the cleaning agent has been processed, sampling is required before filling for quality inspection.

[0003] In existing technologies, sampling operations typically require operators to open the observation port or other openings on the reactor and insert the sampling device inside. This traditional sampling method presents several technical problems. First, opening the reactor for sampling is cumbersome, increasing the workload and time required for operators. Second, when the reactor is opened for sampling, the cleaning agent inside is exposed to the external environment, making it susceptible to contamination by dust, microorganisms, or other impurities in the air, thus affecting the quality and purity of the cleaning agent. Furthermore, frequent opening and closing of the reactor may also affect the stability and safety of the production process.

[0004] Therefore, existing technologies urgently need improvement to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sampling device for the production and processing of cleaning agents.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sampling device for the production and processing of cleaning agents, including a mounting flange for fixing to a reaction vessel, and further including:

[0007] The sampling tube is connected to the mounting flange and extends into the reactor.

[0008] A screw cap is used to seal the upper opening of the sampling tube;

[0009] A sampling shell is configured to slide inside the sampling tube. A counterweight is fixedly connected to the surface of the sampling shell to assist the sampling shell in sliding downward inside the sampling tube.

[0010] The functional section is located on the inner wall of the sampling tube;

[0011] A snap-fit ​​mechanism for selectively engaging or disengaging the sampling housing from the functional section, the snap-fit ​​mechanism comprising:

[0012] A mounting cavity is symmetrically opened on the surface of the sampling shell, and a compression spring is fixedly connected inside the mounting cavity;

[0013] Two wedge-shaped blocks are slidably connected inside the two mounting cavities, respectively, and are subjected to the biasing force of the compression spring to engage with the functional section;

[0014] The drive ring is vertically slidably connected to the outer wall of the sampling shell;

[0015] The side rope is connected to the top of the drive ring, and the upper end of the side rope extends through to the top of the sampling shell.

[0016] The piston is disposed within the sampling housing in a sealed and sliding manner.

[0017] A pull rope, connected to the piston, extends through the upper end of the sampling shell to the top of the sampling shell, and is used to move the piston relative to the sampling shell to create a negative pressure inside the sampling shell for sampling.

[0018] The sampling shell has a tapered opening at one end for sample entry.

[0019] Before producing the cleaning agent, the user first removes the sealing glass from the observation port of the reactor. The device is then fixed to the reactor using the mounting flange, and the opening at the top of the sampling tube is sealed with a screw cap. After the cleaning agent processing is complete in the reactor, the screw cap is unscrewed, and the sampling shell is placed into the sampling tube. The sampling shell, along with the counterweight, slides downwards along the sampling tube under gravity until it reaches the functional section position. At this point, the wedge block, driven by the restoring force of the compression spring, slides away from the sampling shell and inserts into the functional section, locking the sampling shell in a predetermined position. The user then pulls the pull rope, causing the piston to move upwards relative to the sampling shell. The piston moves upwards within the sampling shell, creating a negative pressure that draws the cleaning agent sample from the reactor into the sampling shell. After the piston moves to a certain position, the side rope is pulled, causing the drive ring to slide upwards along the outer wall of the sampling shell until the drive ring drives the wedge block to overcome the spring force of the compression spring and move towards each other, releasing the engagement with the functional section. As the user continues to pull the rope, the entire sampling shell moves upward, removing it from the sampling tube. After the user removes the sampling shell from the sampling tube, they can push the piston to extract the cleaning agent sample inside the shell. The entire process does not require fully opening the reaction vessel, making operation convenient and quick. It effectively avoids contamination of the cleaning agent during sampling, improving production efficiency and product quality.

[0020] Furthermore, the mounting flange is fixedly connected to the sampling tube by threaded connection or welding.

[0021] Furthermore, the counterweight is fixedly connected to the lower outer wall of the sampling shell.

[0022] Furthermore, the functional section has an annular structure, and its inner wall is provided with a groove for engaging with the wedge block.

[0023] Furthermore, the drive ring is positioned below the wedge block.

[0024] Furthermore, the wedge-shaped block has an outwardly inclined slope, and the functional section is an annular inner cavity.

[0025] Furthermore, the drive ring is a circular ring structure and is fitted onto the outer wall of the sampling shell.

[0026] Furthermore, the conical opening is located at the lower end of the sampling shell, and its opening direction is downward.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] By setting up an installation flange and sampling tube, the sampling device can be fixed at positions such as the observation port of the reactor. The sampling shell can be sent into the reactor for sampling without fully opening it, solving the problem of cumbersome sampling operations in existing technologies. The piston inside the sampling shell generates negative pressure by moving a rope, achieving the absorption of the cleaning agent sample, making operation simple and efficient. The inclusion of a functional section and a mechanism consisting of a compression spring, wedge block, drive ring, and side rope allows the sampling shell to be locked when it reaches a predetermined position and unlocked by pulling the side rope after sampling, facilitating the removal of the sampling shell and improving sampling accuracy and convenience. This device allows sampling without opening the reactor, effectively avoiding the risk of contamination of the cleaning agent due to exposure to the external environment during sampling, thus improving the quality and purity of the cleaning agent. Therefore, the sampling device of this invention has a compact structure, is easy to operate, and effectively solves the technical problems of inconvenient sampling operations and easy contamination of the cleaning agent in existing technologies, demonstrating significant technological progress and practical value.

[0034] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0035] In the production and processing of cleaning agents, mixing or reaction usually needs to be completed in a reaction vessel, and sampling is required for quality inspection before filling. However, existing sampling methods often require opening the observation port or other openings of the reaction vessel and manually inserting the sampling device into the vessel. This method is not only cumbersome, but also exposes the cleaning agent to the external environment due to the large observation port, making it highly susceptible to contamination and affecting product quality. To solve this technical problem, this invention provides a sampling device for cleaning agent production and processing. This device can be fixed to the reaction vessel and, through a clever structure, allows sampling without fully opening the reaction vessel, significantly improving operational convenience and reducing the risk of contamination. The core of this device lies in its sampling shell, which can slide inside the sampling tube to take samples, and a locking mechanism for locking the sampling shell in a predetermined position.

[0036] like Figures 1 to 4 The sampling device shown includes a mounting flange 1 for fixing to a reaction vessel, and further includes:

[0037] Sampling tube 3 is connected to mounting flange 1 and extends into the reactor;

[0038] Screw cap 2 is used to seal the upper opening of sampling tube 3;

[0039] The sampling shell 4 is configured to slide inside the sampling tube 3. A counterweight 5 is fixedly connected to the surface of the sampling shell 4 to assist the sampling shell 4 in sliding downward inside the sampling tube 3.

[0040] Functional section 6 is located on the inner wall of sampling tube 3;

[0041] A snap-fit ​​mechanism for selectively engaging or disengaging the sampling shell 4 from the functional section 6, the snap-fit ​​mechanism comprising:

[0042] A mounting cavity is symmetrically opened on the surface of the sampling shell 4, and a compression spring 7 is fixedly connected inside the mounting cavity;

[0043] Two wedge-shaped blocks 8 are slidably connected inside the two mounting cavities, respectively, and are subjected to the biasing force of the compression spring 7 to engage with the functional section 6;

[0044] The drive ring 12 is vertically slidably connected to the outer wall of the sampling shell 4;

[0045] Side rope 11 is connected to the top of drive ring 12, and the upper end of side rope 11 extends through to the top of sampling shell 4.

[0046] Piston 10 is disposed in a sealed and sliding manner within sampling shell 4;

[0047] A pull rope 9 is connected to the piston 10. The upper end of the sampling shell 4 extends through to the top of the sampling shell 4 and is used to move the piston 10 relative to the sampling shell 4 to create a negative pressure inside the sampling shell 4 for sampling.

[0048] Compared with existing technologies, the sampling device of this invention has significant advantages. Existing technologies typically require opening the reactor for manual sampling, which is inconvenient and prone to contamination. This invention, however, fixes the device to the reactor and uses the sampling tube 3 to guide the sampling shell 4 for sampling in a closed or semi-closed environment. Specifically, by incorporating a functional section 6 and a locking mechanism (including a compression spring 7, a wedge block 8, a drive ring 12, and a side rope 11), the sampling shell 4 automatically locks when it reaches the predetermined sampling position, ensuring accurate sampling depth. After sampling, pulling the side rope 11 releases the lock, facilitating the removal of the sampling shell 4. This design avoids the tedious manual insertion of the sampling device into the reactor, reducing labor intensity and improving sampling efficiency. More importantly, because the sampling process takes place in a relatively closed environment, the contact between the cleaning agent and the external environment is greatly reduced, effectively preventing external contaminants from contaminating the cleaning agent and ensuring product quality.

[0049] The working principle of this utility model is as follows: Before producing the cleaning agent, the user first removes the sealing glass of the observation port on the reactor, fixes the device on the reactor using the mounting flange 1, and seals the opening at the upper end of the sampling tube 3 using the screw cap 2. After the cleaning agent processing is completed in the reactor, the screw cap 2 is unscrewed and the sampling shell 4 is placed into the sampling tube 3. The sampling shell 4, in conjunction with the counterweight 5, slides downward along the sampling tube 3 under the action of gravity until it reaches the position of the functional section 6. At this time, the wedge block 8, driven by the restoring force of the compression spring 7, slides away from the sampling shell 4 and inserts into the functional section 6, locking the sampling shell 4 in the predetermined position. At this time, the user pulls the pull rope 9, which drives the piston 10 to move upward relative to the sampling shell 4. The piston 10 moves upward inside the sampling shell 4, creating a negative pressure in the sampling shell 4, thereby drawing the cleaning agent sample from the reactor into the sampling shell 4. After the pull rope 9 moves the piston 10 to a certain position, the side rope 11 is pulled, and the drive ring 12 slides upward along the outer wall of the sampling shell 4 until the drive ring 12 drives the wedge block 8 to overcome the elastic force of the compression spring 7 and move towards each other, thus releasing the engagement with the functional section 6. As the user continues to pull the pull rope 9, the entire sampling shell 4 can be moved upward, allowing it to be removed from the sampling tube 3. After the user removes the sampling shell 4 from the sampling tube 3, the piston 10 can be pushed to remove the cleaning agent sample inside the sampling shell 4. The entire process does not require fully opening the reactor, making the operation convenient and quick, effectively avoiding contamination of the cleaning agent during sampling, and improving production efficiency and product quality.

[0050] In one embodiment of this utility model, the mounting flange 1 is fixedly connected to the sampling tube 3 by threaded connection or welding.

[0051] During implementation, the mounting flange 1 and the sampling tube 3 are fixedly connected by threaded connection or welding. This connection structure is stable and reliable, and can withstand various stresses that the device may encounter during use, ensuring that the sampling device can be firmly fixed on the reactor and preventing loosening or falling off during use.

[0052] As one embodiment of this utility model, the counterweight 5 is fixedly connected to the lower outer wall of the sampling shell 4.

[0053] In practice, by fixing the counterweight 5 to the lower outer wall of the sampling shell 4, this design effectively utilizes gravity to guide the sampling shell 4 to move vertically within the sampling tube 3. This optimized center of gravity position helps prevent the sampling shell 4 from tilting or deflecting during sliding, reducing friction and jamming between the sampling shell 4 and the inner wall of the sampling tube 3. Consequently, the sampling shell 4 can reach the predetermined sampling position more smoothly and steadily, improving the operational reliability and sampling efficiency of the device.

[0054] In one embodiment of this utility model, the functional section 6 is an annular structure, and its inner wall is provided with a groove for engaging with the wedge block 8.

[0055] In implementation, by designing the functional section 6 as a ring-shaped structure with an inner wall groove and engaging it with the wedge block 8, the locking structure becomes more precise and reliable. The groove provides a clear engagement position for the wedge block 8, ensuring that the sampling shell 4 can be accurately locked at the predetermined sampling depth. This structural design avoids relying solely on friction or other uncertain factors for positioning and locking, significantly improving the stability and reliability of the locking mechanism. Therefore, it ensures that each sampling is performed at a precisely controlled depth, improving the accuracy of the sampling operation and further enhancing the practical value of this invention.

[0056] In one embodiment of this utility model, the drive ring 12 is disposed below the wedge block 8.

[0057] As one embodiment of this utility model, the wedge block 8 has an outwardly inclined surface.

[0058] In one embodiment of this utility model, the drive ring 12 is a circular ring structure and is sleeved on the outer wall of the sampling shell 4.

[0059] In implementation, the drive ring 12 is designed as a circular structure and fitted onto the outer wall of the sampling shell 4. This structure is simple, compact, and easy to manufacture and install. The circular structure can evenly distribute the force and has good stability when sliding along the outer wall of the cylindrical sampling shell 4. As the connection point and force application point of the side rope 11, the sliding of the drive ring 12 on the outer wall of the sampling shell 4 can effectively drive the wedge block 8 to move through the side rope 11, realizing the locking or unlocking operation.

[0060] As one embodiment of this utility model, the lower end of the sampling shell 4 has a conical opening 14 for sample entry, and its opening direction is downward.

[0061] In practice, the sampling shell 4 is the container used to actually collect the cleaning agent sample. To effectively obtain samples from the reactor, especially when there may be sediment at the bottom or when it is necessary to obtain bottom liquid, the sampling shell 4 needs to have an inlet that facilitates sample entry. By placing the conical opening 14 at the bottom of the sampling shell 4 with its opening facing downwards, this design maximizes the submersion depth of the sampling shell 4, ensuring that cleaning agent samples from the bottom area of ​​the reactor can be obtained. The conical structure facilitates sample convergence and entry, especially for viscous liquids or cleaning agents containing a small amount of sediment, improving sampling efficiency and completeness. This ensures that the obtained sample is more representative and accurately reflects the overall or bottom quality of the cleaning agent within the reactor.

[0062] Working principle of this utility model:

[0063] Before producing the cleaning agent, the user first removes the sealing glass from the observation port of the reactor. The device is then fixed to the reactor using the mounting flange 1, and the opening at the top of the sampling tube 3 is sealed using the screw cap 2. After the cleaning agent processing is completed in the reactor, the screw cap 2 is unscrewed, and the sampling shell 4 is placed into the sampling tube 3. The sampling shell 4, in conjunction with the counterweight 5, slides downwards along the sampling tube 3 under gravity until it reaches the position of the functional section 6. At this point, the wedge block 8, driven by the restoring force of the compression spring 7, slides away from the sampling shell 4 and inserts into the functional section 6, locking the sampling shell 4 in the predetermined position. The user then pulls the pull rope 9, which moves the piston 10 upwards relative to the sampling shell 4. The piston 10 moves upwards within the sampling shell 4, creating a negative pressure within it, thereby drawing the cleaning agent sample from the reactor into the sampling shell 4. After the pull rope 9 moves the piston 10 to a certain position, the side rope 11 is pulled, and the drive ring 12 slides upward along the outer wall of the sampling shell 4 until the drive ring 12 drives the wedge block 8 to overcome the elastic force of the compression spring 7 and move towards each other, thus releasing the engagement with the functional section 6. As the user continues to pull the pull rope 9, the entire sampling shell 4 can be moved upward, allowing it to be removed from the sampling tube 3. After the user removes the sampling shell 4 from the sampling tube 3, the piston 10 can be pushed to remove the cleaning agent sample inside the sampling shell 4. The entire process does not require fully opening the reactor, making the operation convenient and quick, effectively avoiding contamination of the cleaning agent during sampling, and improving production efficiency and product quality.
