Abstract
Description
Technical Field
[0001] This utility model relates to a device for adding powdered material to a narrow-necked bottle, belonging to the field of product testing technology. Background Technology
[0002] Currently, cement, slag powder, and fly ash are tested according to "GB / T 208-2014 Cement Density Determination Method," while road-grade mineral powder is tested according to "JTG 3432-2024 Highway Engineering Aggregate Test Procedure." The two methods are essentially the same. This test requires entirely manual operation; the powder to be tested is placed in a Leigh flask, and the density is calculated by observing the change in kerosene level in the flask.
[0003] The challenge of this test lies in the process of loading the sample into the Leigh flask. For example, when testing a cement sample, one sample weighs 60g. Because the neck of the Leigh flask is long and narrow, approximately 10mm in diameter, if the cement is added too quickly, it cannot mix rapidly with the kerosene upon initial contact and sinks to the bottom, easily forming sludge near the kerosene surface and clogging the neck. To prevent clogging, a cement sample is typically added in about 200 portions, with shaking performed simultaneously. Clogging is often addressed by vigorous shaking or using a wire to clear the blockage, but this only exacerbates the problem by contaminating the upper part of the neck with kerosene, leading to further blockage and ultimately test failure and retesting. Furthermore, both GB / T 208-2014 and JTG 3432-2024 stipulate that the test requires two parallel experiments, and the entire testing process takes about an hour, resulting in low efficiency and a high rate of operational errors. Utility Model Content
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a device for adding powdered material to a narrow-necked bottle, which is suitable for the method of determining the density of powdered material using instruments such as Leigh flasks with long and narrow necks. It is easy to operate, shortens the detection time, improves work efficiency, reduces labor costs, and has a low cost.
[0005] The device for adding powdered material to a narrow-necked bottle according to this utility model includes a base, a support fixed above the base, a height adjustment device slidably mounted on the support, and a Leigh Burke bottle supported on the base. A funnel and a funnel vibrator are detachably connected to the height adjustment device. The height adjustment device can move up and down along the support, thereby driving the funnel to rise and fall. The funnel is located directly above the Leigh Burke bottle. The base has a cavity, and an ultrasonic generator is installed in the cavity. The probe of the ultrasonic generator is located directly below the Leigh Burke bottle, and the ultrasonic generator is used to stir the mixture in the Leigh Burke bottle.
[0006] The technical solution of this utility model is to provide a device for adding powdered material to a narrow-necked bottle. The funnel vibrator is used to vibrate the funnel to control the rate of powder addition, preventing the powder from splashing kerosene and causing the bottle neck to become blocked. At the same time, ultrasonic waves are used to stir the mixture in the Leigh flask, so that the powder is quickly dispersed and mixed in the kerosene and air bubbles are quickly removed.
[0007] Preferably, the base is provided with a fixing clip, which is located on both sides of the Leigh specific gravity bottle to hold the Leigh specific gravity bottle, restrict the horizontal movement of the Leigh specific gravity bottle, and center the position of the Leigh specific gravity bottle; one end of the fixing clip is provided with an arc-shaped rubber sleeve, and the other end is hinged to the base, and a spring is installed on the fixing clip.
[0008] Preferably, the height adjustment device includes an adjustment slider and a funnel placement frame. The adjustment slider is slidably connected to the support and its position can be locked. The funnel placement frame is fixedly connected to the adjustment sliders on both sides and is used to support the funnel.
[0009] Furthermore, the base is provided with a water storage tank at its center, in which water is placed as a coupling agent, and the probe of the ultrasonic generator is located at the center of the water storage tank.
[0010] Preferably, a light is also installed on one side of the base, and the light is connected to the base via a flexible duct.
[0011] Preferably, the base is equipped with an ultrasonic generator switch, a power regulator, a lighting switch, a funnel vibrator switch, and a power interface. The power regulator is used to adjust the power of the ultrasonic generator, and the power regulator is marked with a suitable power range to prevent the ultrasonic generator power from being too high and causing kerosene cavitation.
[0012] The advantages of this utility model compared with the prior art are:
[0013] The device for adding powdered material to a narrow-necked bottle described in this utility model can shorten the manual operation time in the density detection of powdered material, reducing the manual operation time from one hour to less than ten minutes, greatly improving work efficiency, effectively avoiding re-inspection caused by human error, and reducing the error of human factors in the detection; this utility model is low in cost and convenient to use and maintain.

[0017] like Figure 1-2 As shown, this embodiment is achieved through the following technical solution: It includes a base 1, with a support 9 fixed above the base 1. A height adjustment device is slidably mounted on the support 9, and the base 1 supports a Leigh Burke bottle 4. A funnel 6 and a funnel vibrator 7 are detachably connected to the height adjustment device. The height adjustment device can move up and down along the support 9, thereby driving the funnel 6 to rise and fall. The funnel 6 is located directly above the Leigh Burke bottle 4. The funnel is made of stainless steel, does not generate static electricity, and will not adhere to cement particles, thus reducing detection errors. The base 1 has a cavity, and an ultrasonic generator 12 is installed inside the cavity. The probe of the ultrasonic generator 12 is located directly below the Leigh Burke bottle, and the ultrasonic generator 12 is used to stir the mixture in the Leigh Burke bottle 4.
[0018] In this embodiment, the base 1 is provided with a fixing clip 10, which is located on both sides of the Leigh specific gravity bottle 4. The fixing clip 10 is used to clamp the Leigh specific gravity bottle 4, restrict the horizontal movement of the Leigh specific gravity bottle 4, and center the position of the Leigh specific gravity bottle 4. One end of the fixing clip 10 is provided with an arc-shaped rubber sleeve, and the other end is hinged to the base 1. A spring is installed on the fixing clip 10.
[0019] The height adjustment device includes an adjusting slider 8 and a funnel placement frame 5. The adjusting slider 8 is slidably connected to the support 9, and its position can be locked. The funnel placement frame 5 is fixedly connected to the adjusting sliders 8 on both sides and is used to support the funnel 6. A water storage tank 11 is also provided at the center of the base 1. Water is placed in the water storage tank 11 as a coupling agent, and the probe of the ultrasonic generator 12 is located at the center of the water storage tank 11. A lighting lamp 3 is also installed on one side of the base 1. The lighting lamp 3 is connected to the base 1 via a universal hose 2 and is used to observe the air bubble removal status and the kerosene level. The base 1 is equipped with an ultrasonic generator switch, a power regulator, a lighting lamp switch, a funnel vibrator switch, and a power interface. The power regulator is used to adjust the power of the ultrasonic generator, and a suitable power range is marked on the power regulator to prevent excessive power from the ultrasonic generator 12 from causing kerosene cavitation.
[0020] The method of using this utility model is as follows:
[0021] The powder sample to be tested is placed into funnel 6 using a weighing boat or spatula. The funnel vibrator 7 causes the funnel 6 to vibrate slightly, allowing the powder to be slowly poured into the Leigh flask 4. Under the stirring action of the ultrasonic generator 12, the kerosene and powder vibrate and mix rapidly, preventing the powder from accumulating at the neck of the Leigh flask 4. As the kerosene level rises, the height of funnel 6 is adjusted by adjusting the slider 8 to prevent the tail of the funnel from contacting the kerosene. During the operation, the scale on the neck is illuminated by the lamp 3 for easy observation.
