Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber performance detection, in particular to a device for detecting the drainage property of glass fiber cotton. Background Art

[0002] Glass fiber cotton refers to glass fiber wool, which is an inorganic non-metallic material with advantages such as good insulation, high heat resistance, good corrosion resistance, and high mechanical strength. It is commonly used as thermal insulation materials for buildings or various thermal equipment, such as glass fiber cotton boards, glass fiber cotton roll felts, glass fiber cotton pipe shells, etc.

[0003] After the production of glass fiber cotton and its products, it is necessary to detect their drainage property, that is, the water repellency rate. The water repellency rate refers to the ability of the glass fiber cotton not to absorb water under certain conditions. Due to the surface tension, the internal voids and pores of the glass fiber cotton cannot be penetrated by the liquid. The higher the water repellency rate, the better the thermal insulation and sound insulation performance of the glass fiber cotton.

[0004] The detection method of the water repellency rate of glass fiber cotton usually adopts the immersion method or the dropping method. The detection device of the immersion method includes a water tank and a pressing plate. Add a certain amount of water to the water tank. First, detect the weight of the sample, then put the sample into the water tank, put the pressing plate into the water tank, and clamp the pressing plate with a heavy object to prevent the pressing plate from directly touching the bottom and squeezing the sample. After a period of time, take out the pressing plate, and then clamp the sample to detect its weight. Calculate the weight difference of the sample to determine its water repellency rate, that is, the drainage property.

[0005] Since the metal pressing plate has a certain weight and the experimenters operate the pressing plate manually, the existing detection device can only detect 1-2 pieces at a time. When the number of samples increases, the volume and weight of the metal pressing plate will increase, which increases the operation difficulty of the experimenters, is time-consuming and laborious, and reduces the convenience of detection. Sometimes it is also necessary to detect the drainage property of the sample at a specific temperature during the inspection, so it is also necessary to adjust the water temperature in the water tank. In the prior art, usually the experimenters first adjust the test temperature by mixing cold and hot water, and then pour the adjusted water into the water tank. The operation is inconvenient and the temperature control effect is poor, thus reducing the accuracy of the detection result, and therefore reducing the convenience and accuracy of the detection of the drainage property of glass fiber cotton. Content of the Utility Model

[0006] In order to improve the convenience and accuracy of the detection of the drainage property of glass fiber cotton, the utility model provides a device for detecting the drainage property of glass fiber cotton.

[0007] A device for detecting the drainage property of glass fiber cotton provided by this application adopts the following technical scheme:

[0008] A glass fiber cotton drainage detection device, including a frame and a water tank arranged on the frame. A pressing plate for pressing the sample into the water tank is arranged in the water tank. A driving member for driving the pressing plate to move up and down is arranged on the frame. A temperature control mechanism for adjusting the water temperature is arranged in the water tank.

[0009] By adopting the above technical solution, water is added into the water tank, the water temperature is adjusted by the temperature control mechanism, the sample to be tested is placed in the water tank, the driving member is started to push the pressing plate into the water tank, the pressing plate moves to press the sample to be tested under the water. During this period, the temperature control mechanism controls the water temperature to be constant. After reaching the inspection duration, the driving member is started to drive the pressing plate to move back, the sample to be tested floats to the water surface, and the inspection personnel clamp out the sample for testing. The drainage property is determined according to the weight difference before and after, so as to realize the inspection of multiple samples at a time, and cooperate with the temperature control mechanism to improve the stability of the detection, thus improving the convenience and accuracy of the glass fiber cotton drainage detection.

[0010] Optionally, a plurality of water passing holes for passing water are uniformly distributed on the pressing plate.

[0011] By adopting the above technical solution, the water in the water tank flows through the water passing holes, reducing the probability that the contact surface between the sample and the pressing plate cannot contact water, thus improving the convenience and accuracy of the glass fiber cotton drainage detection.

[0012] Optionally, a vertically extending reinforcing plate is arranged at the edge of the pressing plate. The driving member is a cylinder and there are two cylinders. The two cylinders are respectively connected to two relatively arranged reinforcing plates on the pressing plate.

[0013] By adopting the above technical solution, when the cylinder is started, it drives the pressing plate to move up and down through the reinforcing plate. The reinforcing plate increases the overall strength of the pressing plate and at the same time increases the convenience of connecting the pressing plate and the cylinder.

[0014] Optionally, the temperature control mechanism includes:

[0015] An electric heating tube arranged in the water tank;

[0016] A temperature sensor arranged in the water tank and used for detecting the water temperature in the water tank;

[0017] A control component arranged on the frame and used for controlling the electric heating tube to work.

[0018] By adopting the above technical solution, during the process of the sample being immersed in water, the temperature sensor detects the water temperature in the water tank and transmits the water temperature information to the control component. The control component starts to control the electric heating tube to work, so that the water temperature reaches and remains at the required value for detection, thus realizing the water temperature control in the process of glass fiber cotton drainage detection, without manual mixing of cold and hot water, and the water temperature remains constant during the immersion process, thereby improving the convenience and accuracy of the glass fiber cotton drainage detection.

[0019] Optionally, the control component includes:

[0020] A temperature controller, which is arranged on the frame and the electric heating tube is connected to the temperature controller;

[0021] A control unit, which is arranged on the frame. The signal output end of the temperature sensor is electrically connected to the first signal input end of the control unit, and the first signal output end of the control unit is electrically connected to the signal input end of the temperature controller.

[0022] By adopting the above technical solution, the temperature sensor transmits the water temperature information to the control unit, and the control unit controls the electric heating tube to work through the temperature controller, so as to adjust the water temperature in the water tank, thereby improving the convenience of water temperature control in the detection process of the drainage property of fiberglass cotton.

[0023] Optionally, a timer is further arranged on the frame. The signal output end of the timer is electrically connected to the second signal input end of the control unit, and the second signal output end of the control unit is electrically connected to the signal input end of the solenoid valve that controls the movement of the cylinder.

[0024] By adopting the above technical solution, the immersion time is input on the timer. When the time arrives, the timer transmits the information to the control unit, and the control unit controls the cylinder to move back through the solenoid valve. The cylinder drives the pressing plate to move back, and the sample floats to the water surface. After the inspector clamps out the sample for testing, the convenience of the drainage property detection of fiberglass cotton is improved.

[0025] Optionally, a limiting plate is arranged in the water tank. When the pressing plate moves in place, the limiting plate abuts against the pressing plate.

[0026] By adopting the above technical solution, the limiting plate limits the maximum displacement of the movement of the pressing plate, thereby reducing the probability that the pressing plate directly moves down to touch the bottom wall of the water tank. This not only reduces the probability of the pressing plate being damaged by collision, but also reduces the probability that the sample to be tested is extruded and deformed by the pressing plate, so as to improve the convenience and accuracy of the drainage property detection of fiberglass cotton.

[0027] Optionally, a heat insulation layer is detachably arranged between the frame and the water tank.

[0028] By adopting the above technical solution, the water tank is insulated by the heat insulation layer, and the speed of temperature dissipation is reduced, thereby saving energy.

[0029] Optionally, a liquid level sensor is arranged on the water tank.

[0030] By adopting the above technical solution, the liquid level sensor detects the liquid level in the water tank, so as to facilitate the inspector to control the water level, thereby improving the convenience of the drainage property detection of fiberglass cotton.
