Description

Technical Field

[0001] This utility model relates to the field of cement density testing technology, specifically a constant temperature stirring cement density measuring device. Background Technology

[0002] Cement, as an indispensable basic material in construction, directly affects the structural strength, durability and service life of buildings. Among many performance indicators, the density of cement is a key parameter, which is not only related to the physical properties of cement, but also closely related to its chemical composition, manufacturing process and actual application effect.

[0003] For example, the announcement number CN217638532U describes a cement density measuring device, which includes a water bath, a sample bottle, a measuring tube, an inlet pipe, an outlet pipe, a constant temperature water bath, and a circulating water pump. The sample bottle and the measuring tube are connected and placed together in the water bath. The inlet pipe and the outlet pipe are both connected between the water bath and the constant temperature water bath. The circulating water pump is set in the constant temperature water bath and is connected to the inlet pipe and the outlet pipe respectively.

[0004] The existing technology has the following technical problems: When testing cement samples in a Leigh flask, the existing density measuring device places the Leigh flask in a constant temperature water bath. However, it is not convenient to read the scale markings on the Leigh flask when it is placed in the constant temperature water bath. At the same time, during the process of taking the Leigh flask out of the constant temperature water bath, the final test result is easily affected by temperature changes.

[0005] Therefore, we propose a constant-temperature mixing cement density measuring device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a constant-temperature stirring cement density measuring device to solve the problems mentioned in the background art. Currently available density measuring devices on the market, when testing cement samples in Leigh flasks, place the Leigh flask in a constant-temperature water bath. However, when the Leigh flask is placed in the constant-temperature water bath, it is inconvenient to read the scale markings on the Leigh flask. At the same time, during the process of removing the Leigh flask from the constant-temperature water bath for reading, the final test results are easily affected by temperature changes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature stirring cement density measuring device, comprising a constant temperature water tank, an insertion interface in the middle of the constant temperature water tank, a Lee's flask body inserted inside the constant temperature water tank, an ultrasonic stirrer installed on the constant temperature water tank, a transparent window provided on the side of the constant temperature water tank, and a limiting clamping component for fixing the Lee's flask body installed at the upper end of the constant temperature water tank.

[0008] Preferably, the stirring end of the ultrasonic stirrer is located in a constant temperature water tank, and multiple ultrasonic stirrers are evenly distributed at equal intervals on the constant temperature water tank.

[0009] By adopting the above technical solution, the ultrasonic stirrer can be used to easily stir the medium in the constant temperature water bath, so that the medium can be heated evenly.

[0010] Preferably, the transparent window is symmetrically arranged about the vertical central axis of the constant temperature water tank, and the transparent window is set as a transparent and visible magnifying glass lens.

[0011] By adopting the above technical solution and using a transparent and visible magnifying glass lens, readings can be taken without removing the Leigh bottle itself.

[0012] Preferably, the limiting clamping component includes a movable frame, a central screw, a limiting clamp, a buffer pad, and a built-in spring. The movable frame is located above the constant temperature water tank. A central screw is installed in the middle of the movable frame, and a limiting clamp is provided on the inner side of the end of the movable frame. A buffer pad is installed at the end of the limiting clamp that contacts the Leigh bottle body, and the lower end of the limiting clamp is connected to the constant temperature water tank through the built-in spring.

[0013] By adopting the above technical solution, the built-in spring enables the limiting clamp to reset and rebound after it moves on the constant temperature water tank.

[0014] Preferably, the central screw and the middle part of the movable frame are threaded together, and the upper end of the movable frame and the constant temperature water tank are slidably connected, and the cross-section of the movable frame is set as a "U" shaped structure.

[0015] By adopting the above technical solution, the sliding of the mobile frame on the constant temperature water tank can prevent the mobile frame from rotating synchronously with the central screw.

[0016] Preferably, the inner side of the end of the movable frame is in contact with the arc surface of the limiting clamp in the initial state, and the contact surface between the end of the movable frame and the limiting clamp is set as an inclined surface.

[0017] By adopting the above technical solution, the movement of the movable frame enables the inclined surface to squeeze and push the arc-shaped end of the limiting clamp.

[0018] Preferably, the contact surface between the end buffer pad of the limiting clamp and the body of the Lee bottle is set as a rough surface, and the limiting clamp forms an elastic telescopic structure through the built-in spring and the upper end of the constant temperature water tank.

[0019] By adopting the above technical solution, the rough surface of the buffer pad can improve the contact friction between the buffer pad and the body of the Leigh bottle.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the constant temperature stirring cement density measuring device, by adding a transparent window in the constant temperature water bath, makes it easy to directly read the scale markings on the Leigh flask using the transparent window;

[0021] 1. Equipped with an ultrasonic stirrer, which can easily agitate the medium in the constant temperature water tank, improve the heating rate inside the constant temperature water tank, and facilitate the rapid heating of the Leigh bottle body.

[0022] 2. A transparent window is provided. By setting a transparent window on the side of the constant temperature water bath, it is convenient to read the scale on the surface of the Leigh flask body using a transparent and magnifying glass lens during the measurement process, avoiding the need to remove the Leigh flask body from the constant temperature water bath to read the scale.

[0023] 3. A limiting clamp is provided. The rotation of the central screw allows the threaded movable frame to move. The movement of the movable frame can compress the limiting clamp, thereby clamping and fixing the Leigh bottle body. At the same time, the buffer pad at the end of the limiting clamp can provide a clamping and buffering effect on the Leigh bottle body, preventing excessive clamping force from damaging the Leigh bottle body.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: Please refer to Figures 1-6 Existing density measuring devices test cement samples in Leigh flasks by placing the flask in a constant-temperature water bath. However, placing the flask in the bath makes it difficult to read the scale markings. Furthermore, temperature changes during the removal of the flask from the bath can easily affect the final test results. To address this technical problem, this embodiment discloses the following: a constant-temperature stirring cement density measuring device, comprising a constant-temperature water tank 1, an insertion interface 2 in the middle of the water tank 1, a Leigh flask body 3 inserted inside the water tank 1, an ultrasonic stirrer 4 mounted on the water tank 1, and a transparent window 5 on the side of the water tank 1. The stirring end of the ultrasonic stirrer 4 is located in the water tank 1, and multiple ultrasonic stirrers 4 are evenly distributed at equal intervals on the water tank 1. The transparent window 5 is symmetrically arranged about the vertical central axis of the water tank 1 and is a transparent, magnifying glass lens.

[0033] When it is necessary to determine the density of cement, anhydrous kerosene is injected into the Leigh flask body 3, the stopper is closed, and the Leigh flask body 3 is placed in the constant temperature water tank 1, with the scale part immersed in the water. The initial reading is recorded. Then, the Leigh flask body 3 is removed from the constant temperature water tank 1, and the cement sample is placed into the Leigh flask body 3. The Leigh flask body 3 is then placed back into the constant temperature water tank 1, and the second reading is recorded. The constant temperature water tank 1 has a transparent window 5 on its side, so the reading can be taken without removing the Leigh flask body 3. The cement volume should be the second reading minus the initial reading, which is the volume of anhydrous kerosene displaced by the cement. Then, the density of cement can be calculated using the density formula.

[0034] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. This example discloses the following technical content: A limiting clamping component 6 for fixing the Leigh flask body 3 is installed at the upper end of the constant temperature water tank 1. The limiting clamping component 6 includes a movable frame 601, a central screw 602, a limiting clamping plate 603, a buffer pad 604, and an internal spring 605. The movable frame 601 is located above the constant temperature water tank 1. A central screw 602 is installed in the middle of the movable frame 601, and a limiting clamping plate 603 is provided on the inner side of the end of the movable frame 601. A buffer pad 604 is installed at the end of the limiting clamping plate 603 that contacts the Leigh flask body 3. The lower end of the clamping plate 603 is connected to the constant temperature water tank 1 via the built-in spring 605. The central screw 602 and the middle part of the moving frame 601 are threadedly connected, and the upper end of the moving frame 601 and the constant temperature water tank 1 are slidably connected. The cross-section of the moving frame 601 is set as a "U" shaped structure. The inner side of the end of the moving frame 601 is in contact with the arc surface of the limiting clamping plate 603 in the initial state. The contact surface between the end of the moving frame 601 and the end of the limiting clamping plate 603 is set as an inclined surface. The contact surface between the buffer pad 604 at the end of the limiting clamping plate 603 and the body 3 of the Lee bottle is set as a rough surface. The limiting clamping plate 603 forms an elastic telescopic structure with the upper end of the constant temperature water tank 1 via the built-in spring 605.

[0035] During the cement sealing test, the Lee's bottle body 3 is placed into the constant temperature water tank 1 through the insertion interface 2. Then, the central screw 602 is rotated. The rotation of the central screw 602 causes the threaded movable frame 601 to move. The movement of the movable frame 601 can use the inclined side to squeeze the arc-shaped end of the limiting clamp 603. After being compressed, the limiting clamp 603 moves towards the center of the constant temperature water tank 1. The movement of the limiting clamp 603 can clamp and fix the Lee's bottle body 3, thereby ensuring the stability of the Lee's bottle body 3. The end of the limiting clamp 603 is provided with a buffer pad 604. The elastic deformation of the buffer pad 604 can play a clamping and buffering role when clamping the Lee's bottle body 3, avoiding excessive clamping force that could damage the Lee's bottle body 3.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
