Description

Technical Field

[0001] This utility model relates to the technical field of waterproof performance index determination of waterproof membranes, specifically to a condensate water-saving device for determining the soluble content of waterproof membranes. Background Technology

[0002] Waterproof membranes are mainly used in large-scale construction projects, green roofs, pools, canals, tunnels, basements, garages, subways, and other projects. The determination of the soluble content, a key indicator of their waterproof performance, is extremely important. The soluble content refers to the mass of material dissolved by solvents such as trichloroethylene in a unit area of ​​asphalt waterproof membrane. Materials with insufficient soluble content have poor waterproof performance, durability, and aging resistance.

[0003] According to GB / T328.26-2007 "Test Methods for Waterproof Building Membranes - Soluble Content of Bituminous Waterproof Membranes", the soluble content is determined by Soxhlet extraction. The solvent used in Soxhlet extraction is trichloroethylene, which is insoluble in water. Its boiling point is 83℃ and its condensation point is 62℃. The condenser of the Soxhlet extractor needs to be cooled by flowing water. The water flow rate determines the efficiency of the test. In the existing technology, tap water (about 18℃) is mostly used in a non-circulating cooling method. During the test, first place the waterproof membrane sample in the container. Then, connect the tap water pipe to the instrument's inlet and the outlet to the wastewater tank. Heat the flask until the solvent trichloroethylene boils and forms vapor. The trichloroethylene vapor enters the outer wall of the condenser tube through the conduit and is cooled by the tap water. After condensation, the liquid droplets fall into the container containing the waterproof membrane sample and dissolve its soluble components. The trichloroethylene droplets continue to drip until the liquid level reaches the top of the siphon tube, after which it flows back into the flask through the siphon tube. The flask is continuously heated, and this cycle is repeated 7 times (approximately 7 hours). The soluble components of the waterproof membrane sample are completely dissolved in the trichloroethylene solvent, and the test is then completed.

[0004] Existing technology directly uses tap water as cooling water. In the experiment, the average temperature of tap water was 18℃. One set of experiments required about 7 hours to condense 83℃ trichloroethylene vapor to 62℃ and circulate it. The flow rate in the conduit was 1.5m / s and the pipe diameter was 10mm. One set of experiments required about 1 ton of water, which was a serious waste of water resources. Moreover, because the tap water pressure and flow rate were insufficient, it was impossible to conduct multiple sets of experiments simultaneously, resulting in relatively low experimental efficiency.

These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] The accompanying drawings in this specification are schematic diagrams used to illustrate the concept of this utility model, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. To avoid obscuring the view and to more clearly display the content of the drawings, some components are not drawn in some drawings. The same reference numerals are used to indicate the same parts.

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only for explaining this utility model and are not intended to limit the scope of this utility model. The following description, in conjunction with... Figs. 1-3The preferred embodiments of this utility model will be described in further detail below:

[0025] like Figs. 1-3 As shown, a preferred embodiment of this utility model for determining the soluble content of waterproof membrane includes a water tank 1 and a water pump 2. The water tank 1 contains condensate required for cooling the Soxhlet extraction process. A water supply pipe interface 5 is provided on the top of the water tank 1, which is connected to the condensate source through a water supply pipe. The water pump 2 is fixedly mounted on the water tank 1, and its outlet serves as a condensate inlet interface 10, which is connected to the condensate inlet of the Soxhlet extractor through a condensate pipe. A condensate pipe return interface 11 is also provided on the top of the water tank 1, and the condensate pipe return interface 11 is connected to the condensate outlet of the Soxhlet extractor through a condensate pipe.

[0026] The specific size and form of the water tank 1 can be designed according to actual needs. For example, it can be designed as a box with an open top or a closed box with a top cover. In order to ensure the smooth progress of the test and prevent dust, insects and other impurities from falling into the water tank 1 and affecting the water quality, resulting in pipe blockage or reduced flow of the water pump 2, in some preferred embodiments, the water tank 1 is designed as a closed box with a top cover. The bottom of the water tank 1 is provided with a drain pipe interface 9. By connecting the drain pipe to the drain pipe interface 9, the condensate in the water tank 1 can be drained and replaced regularly to clean the water scale in the box and avoid the accumulation of scale on the inner wall. On this basis, in order to reduce the difficulty of pumping water and avoid negative pressure inside the box, making the pumping smoother, the top cover of the water tank 1 is also provided with an exhaust hole 12. Of course, the holes of the exhaust hole 12 need to be covered with a mesh screen to prevent dust and insects from falling in and affecting the water quality.

[0027] To reduce the difficulty of water replenishment and achieve automatic water replenishment, in some preferred embodiments, the outer end of the water replenishment pipe interface 5 is directly connected to the water source via a water pipe, and its inner end extends into the water tank 1. A float valve 6 is installed to control the opening and closing of the water replenishment pipe interface 5. The inlet water level (lowest water level 15 in the water tank 1) and the stop water inlet water level (highest water level 14 in the water tank 1) of the float valve 6 need to be set based on a comprehensive consideration of the volume of the water tank 1 and the water consumption. Furthermore, to prevent water from failing to enter the water replenishment pipe when the float valve 6 malfunctions... To address the issue of stopping when the water level exceeds the maximum water level 14, the top of the water tank 1 is also equipped with an overflow pipe interface 8. Of course, the height of the overflow pipe interface 8 must not be lower than the maximum water level 14 in the water tank 1 when the float valve 6 stops water intake. Moreover, under normal circumstances, the water level at which the float valve 6 stops water intake (i.e., the maximum water level 14 in the water tank 1) should be set at a height that is flush with the bottom of the condensate return water interface 11, so as to make full use of the internal space of the water tank 1 while reducing the difficulty of condensate return water and avoiding the waste of pumping power of the water pump 2.

[0028] To improve experimental efficiency and ensure that multiple sets of experiments can be conducted simultaneously, the water pump 2 includes multiple units, each of which operates independently. Each water pump 2 is connected to a Soxhlet extractor through a separate condenser pipe. In this case, the size of the water tank 1 needs to be optimized according to the number of experimental sets designed to ensure sufficient condensate water in the tank. Of course, since the multiple water pumps 2 are designed independently in parallel, the top of the water tank 1 also needs to be equipped with a corresponding number of condenser pipe return water interfaces 11 according to the number of experimental sets designed.

[0029] To accelerate the heat dissipation efficiency of the pump set and reduce the operating noise of the pump set, in some preferred embodiments, the water pump 2 is a submersible pump, and the water pump 2 is fixed to the inner wall of the water tank 1 by a suction cup 3. On this basis, in order to more conveniently realize the start and stop control of the water pump 2, a control panel 4 for controlling the start and stop of the water pump 2 is also fixedly installed on the water tank 1. The control panel 4 is electrically connected to the water pump 2. Of course, when there are multiple water pumps 2, the control panel 4 is electrically connected to each water pump 2, and the control panel 4 controls the start and stop of each water pump 2 through different buttons to ensure that each water pump 2 can work independently without interfering with each other.

[0030] In addition to the closed design of the water tank 1, a level gauge 7 is also installed on the water tank 1 to display the water level in real time in order to make it easier to observe the water level inside the water tank 1.

[0031] Of course, considering that the temperature of the condensate in water tank 1 will rise as the experiment progresses and the condensation effect will decrease, in order to address this problem, cooling equipment such as exhaust fans and water bath jackets can be installed in water tank 1. Alternatively, a drain pipe can be connected to drain pipe interface 9 and some water can be discharged periodically to refresh the condensate in water tank 1, thereby achieving the purpose of reducing the temperature of the condensate in water tank 1.

[0032] Example 1

[0033] Considering the simultaneous support of six independent test groups, water tank 1 is made of 304 stainless steel plate, with a length of 700mm, a width of 500mm, and a height of 400mm. Multiple ear plates 13 are installed on the top of water tank 1 to facilitate hoisting, transfer, or temporary fixing. The pump set consists of six 10W small water pumps 2 connected in parallel, each operating independently. To ensure rapid heat dissipation and low noise, all pumps are submersible pumps. The control panel 4 consists of six buttons and a power indicator light. Each button controls the on / off status of one submersible pump. Condensate is stored in water tank 1 to form circulating water. Six 10W submersible booster pumps are used to increase the water flow velocity in the conduit to 3m / s, improving cooling efficiency. Experiments have determined that the dimensions of water tank 1 only need to be 700*500*4mm. 00mm, meaning that approximately 0.14 tons of water is sufficient for 6 groups of tests to be conducted simultaneously, and 6 groups of tests can be completed in just 3.5 hours. Of course, the number of test groups (up to 6 groups in this embodiment) can be determined according to requirements. Since each water pump 2 works independently, during the test, it is only necessary to connect the Soxhlet extractor to the corresponding selected water pump 2 through a condenser tube, and further connect the Soxhlet extractor to the corresponding condenser tube return water interface 11 at the water tank 1 through the condenser tube. Then, the corresponding selected water pump 2 can be turned on by pressing the corresponding button on the control panel 4. This utility model not only satisfies the design purpose of condensate water recycling, but also maintains the flow rate of condensate water in the condenser tube, so that the solvent vapor in the Soxhlet extractor can quickly condense and extract the soluble substances in the sample, thereby improving the test efficiency.

[0034] The preferred implementation scheme in this embodiment costs approximately 1,000 yuan in total and requires only 0.14 tons of water to support six sets of tests simultaneously. Compared to the scheme of directly using tap water as cooling water, it has significant time and economic benefits.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
