Technical Field
[0001] This utility model relates to the field of foaming agent performance testing technology, and in particular to a high-temperature foaming agent performance testing device. Background Technology
[0002] Foaming agents are chemical substances that can significantly reduce the surface tension of a liquid, thereby promoting the formation of large amounts of stable foam from air within the liquid. Their core value lies in controlling the generation and stabilization of bubbles, and they are widely used in mineral processing, oil extraction, and building materials.
[0003] Before using foaming agents, performance testing is required, mainly divided into static performance evaluation and dynamic performance evaluation. Among them, the half-life test for static performance mainly measures the time required for half of the foam to separate into liquid (the longer the time, the better the foam stability). Currently, when using conventional testing instruments to test the half-life, it is necessary to observe and record for a long time. During the observation process, it is difficult to observe the total amount of foam, which makes it difficult to accurately record the time for half of the foam to separate into liquid, resulting in inaccurate half-life test data.
[0004] Therefore, it is necessary to provide a new high-temperature foaming agent performance testing device to solve the above-mentioned technical problems. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0017] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0018] Please see Figures 1 to 5 This utility model provides a high-temperature foaming agent performance testing device, which includes: The base 1 and a vertical plate 11 disposed on one side of the base 1. A support arm 12 is fixedly installed on one side of the bottom end of the vertical plate 11. An L-shaped frame 13 is fixedly installed between the vertical plate 11 and the base 1. A capacity cylinder 2 is installed on the support arm 12. A hollow tube 3 is installed at the bottom of the volumetric cylinder 2. A liquid separation component 4 is installed inside the hollow tube 3. The liquid separation component 4 includes a riser tube 41, which is slidably installed in the hollow tube 3. A bottom tray 42 is installed on the outer wall of the top end of the riser tube 41. A valve seat 43 is embedded in the inner cavity of the top end of the riser tube 41. A through hole is opened in the middle of the valve seat 43, and a valve stem 44 is slidably installed thereon. A mesh-like liquid separation plate 45 is installed at the top end of the valve stem 44. A retaining ring 451 is fixedly installed on the outer wall of the liquid separation plate 45. The outer wall of the retaining ring 451 slides with the inner wall of the volumetric cylinder 2. Several water blocking columns 452 are evenly installed at the bottom end of the retaining ring 451. A drain hole 401 is opened on the bottom tray 42 to be inserted and matched with the water blocking columns 452. A stirring mechanism 6 is installed on the crossbeam of the L-shaped frame 13. Camera 7 and camera 8 are installed on the L-shaped frame 13. Camera 7 is aligned with the capacity cylinder 2, and camera 8 is aligned with the lifting pipe 41. Both camera 7 and camera 8 are electrically connected to a control terminal 9. The control terminal 9 is electrically connected to the stirring mechanism 6. Both the capacity cylinder 2 and the lifting pipe 41 are transparent and have capacity scales. The liquid analysis assembly 4 also includes a sealing plug 411 and an electric push rod 49. The sealing plug 411 is embedded in the bottom end of the lifting tube 41, and the sealing plug 411 has a through hole through which the valve stem 44 passes. The bottom end of the valve stem 44 passes through the sealing plug 411 and is fixedly installed with a baffle 46. A limit spring 47 is fixedly installed on the baffle 46, and the top end of the limit spring 47 is fixedly connected to the sealing plug 411. The electric push rod 49 is fixedly installed on the support arm 12 and is electrically connected to the control terminal 9. A connecting plate 48 is fixedly installed on the telescopic end of the electric push rod 49. The connecting plate 48 is fixedly connected to the bottom side wall of the lifting tube 41. A limit screw 481 is threaded on the connecting plate 48. The bottom end of the limit screw 481 passes through the support arm 12 and is positioned directly above the baffle 46. It should be noted that during testing, the foaming agent liquid is poured into the top of the measuring cylinder 2. Then, the stirring mechanism 6 is controlled by the control terminal 9 to agitate the foaming agent liquid in the measuring cylinder 2 to generate gas. At this time, the lifting pipe 41 drives the bottom tray 42 to the bottom of the inner cavity of the measuring cylinder 2. When the agitation generates the set amount of bubbles, the electric push rod 49 is controlled to push the lifting pipe 41 upward through the connecting plate 48. During the upward pushing process, under the limit of the limit spring 47, the valve stem 44 is fixed on the valve seat 43, sealing the inner cavity of the lifting pipe 41. At this time, the water-blocking column 452 of the liquid separation plate 45 is located directly above the drain hole 401. In this way, during the movement, the liquid can flow along the drain hole 401. The rise is stopped when the top of the bottom tray 42 is level with the bubble boundary line. Then, the limit screw 481 is quickly turned so that its bottom contacts the baffle 46, and the baffle 46 is gradually pushed downward. During the displacement, the valve rod 44 is pulled down along the valve seat 43, thereby pulling the water blocking column 452 into the drain hole 401 until the retaining ring 451 is attached to the top of the bottom tray 42. At this time, the valve seat 43 is opened, so that the liquid precipitated from the bubbles only flows into the riser pipe 41. The entire process of bubble precipitation is recorded by camera 7 and camera 8 until all bubbles have finished precipitating liquid. After completion, the amount of liquid is queried according to the total amount of liquid, so that the half-life of the foaming agent can be measured more accurately.
[0019] It should also be noted that the control terminal 9 is equipped with a PLC controller for controlling the operation of the electric push rod 49 and the stirring mechanism 6, and is also equipped with a PLC controller for receiving data captured by camera 7 and camera 8 to control the entire detection process. The control terminal 9 is also equipped with a touch screen for inputting commands and performing data query operations.
[0020] In this embodiment: a conical sealing surface is provided at the bottom of the valve seat 43, and a sealing guide is provided on the valve stem 44 to seal in contact with the conical sealing surface. The valve stem 44 uses the sealing guide to seal in contact with the conical sealing surface. The height of the through hole of the valve seat 43 and the length of the sealing guide inserted into the through hole of the valve seat 43 are adapted to the movement stroke of the water blocking column 452. This ensures that when switching, the valve seat 43 can remain closed when the water blocking column 452 is inserted into the drain hole 401. When the water blocking column 452 is inserted into the position, the valve seat 43 is in the open state.
[0021] Furthermore, in order for the liquid released from the bubbles to flow into the riser pipe 41 more quickly, a water guide bevel is provided on the top of the bottom tray 42 inside the drain hole 401, and the water guide bevel is used for guiding the flow.
[0022] In the embodiments of this utility model, please refer to Figures 1 to 5The support arm 12 is equipped with a constant temperature water bath 5 that encloses the capacity cylinder 2. The body of the constant temperature water bath 5 is transparent and electrically connected to the control terminal 9. The top of the constant temperature water bath 5 is provided with a through hole through which the capacity cylinder 2 passes.
[0023] It should be noted that the constant temperature water bath 5 can simulate the performance of foaming agents at different high temperatures, making the performance testing of foaming agents more closely resemble the actual high temperature usage environment and improving the accuracy of the simulation.
[0024] In the embodiments of this utility model, please refer to Figures 1 to 5 The stirring mechanism 6 includes an electric push rod 61, which is fixedly mounted on an L-shaped frame 13 and electrically connected to a control terminal 9. A hanger 62 is fixedly mounted on the telescopic end of the electric push rod 61, and a motor 63, which is electrically connected to the control terminal 9, is fixedly mounted on the hanger 62. A stirring rod 64 is driven to the output end of the motor 63, and a honeycomb-shaped stirring head 65 is fixedly mounted at the bottom end of the stirring rod 64.
[0025] It should be noted that when the stirring mechanism 6 is in use, the control electric push rod 61 pushes the stirring head 65 on the hanger 62 into the container 2, and then the motor 63 is started to drive the stirring rod 64 to drive the stirring head 65 to rotate in the container 2. The honeycomb-shaped stirring head 65 rotates in the container 2, and the honeycomb structure allows the foaming agent to foam quickly.
[0026] In this embodiment: to prevent the foaming agent liquid from splashing during stirring, the bottom of the hanger 62 is provided with a cover plate that seals the top of the capacity cylinder 2, so as to seal the capacity cylinder 2 during stirring.
[0027] The working principle of the high-temperature foaming agent performance testing device provided by this utility model is as follows: In use, the foaming agent liquid is poured into the top of the measuring cylinder 2. Then, the constant temperature water bath 5 is controlled to simulate a high-temperature environment. The electric push rod 61 pushes the stirring head 65 on the hanger 62 into the measuring cylinder 2. Then, the motor 63 is started to drive the stirring rod 64 to drive the stirring head 65 to rotate inside the measuring cylinder 2. The honeycomb-shaped stirring head 65 rotates inside the measuring cylinder 2. The honeycomb structure allows the foaming agent to foam quickly. When the set amount of bubbles is generated, the electric push rod 61 is reset. Then, the electric push rod 49 is controlled to push the lifting pipe 41 to rise through the connecting plate 48. When it rises to the top of the bottom tray 42 and is level with the bubble boundary line, the foaming agent is lifted into the cylinder. Stop the ascent, then quickly tighten the limit screw 481 so that its bottom contacts the baffle 46, and gradually push the baffle 46 downward. During the displacement, pull the valve rod 44 downward along the valve seat 43, thereby pulling the water blocking column 452 into the drain hole 401 until the retaining ring 451 is attached to the top of the bottom tray 42. At this time, the valve seat 43 is opened, so that the liquid precipitated from the bubbles only flows into the riser pipe 41. The entire process of the bubbles precipitating liquid is recorded by camera 7 and camera 8 until all the bubbles have finished precipitating liquid. After completion, the amount of liquid is queried according to the total amount of liquid, so that the half-life of the foaming agent can be measured more accurately.
[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
