Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a gypsum self-leveling oven-dry strength dryer. Background Technology

[0002] In the production of gypsum-based self-leveling mortar, it is necessary to conduct an oven-dry strength test on the gypsum-based self-leveling mortar according to JC / T 1023-2021. The specific test process is to place the mortar under standard test conditions for 28 days ± 8 hours, and then put it in an oven at (40 ± 2) ℃ to dry to constant weight (the constant weight is defined as a decrease in specimen mass of no more than 1g after 24 hours).

[0003] Because different types of gypsum require different amounts of water, the drying time to constant weight also varies. During testing, operators need to manually take the test strips out of the oven and weigh them on a balance every day, which takes a lot of time and manpower and is inefficient. Therefore, improvements are needed. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1 The embodiments of this utility model include:

[0022] A gypsum self-leveling oven-dry strength dryer, the structure of which includes: a machine body 1, a drying chamber 2, a chamber door 3, a controller, a display screen 4, a working platform 5, a product tray 6, a weight sensor, a heating wire 7, an air vent grille 8, and a temperature monitoring device 9.

[0023] The drying chamber is mounted on the machine body and has an openable door. A display screen is mounted on the drying chamber or the machine body and is connected to the controller. A work platform is connected to the drying chamber via a push-pull guide rail 11. Heating wires are installed around the work platform and / or on its top. An air vent grille is installed on the top of the drying chamber. Several temperature monitoring devices are installed inside the drying chamber or on its inner side wall to monitor the temperature inside the drying chamber in real time. The temperature monitoring devices are connected to the controller to provide real-time feedback on the drying temperature.

[0024] In some embodiments of this application, multiple temperature monitoring devices are evenly distributed inside the drying chamber to improve the accuracy and stability of temperature detection and ensure the drying effect.

[0025] The work platform is equipped with a support 10, and each support is fixedly connected to a product tray for preventing the test strips from falling. Each product tray is also connected to several weight sensors to monitor the weight of the test strips on the product tray in real time. The weight sensors are connected to the controller to send real-time weight change information to the controller so that the controller can calculate the weight change of the test strips.

[0026] In some embodiments of this application, multiple product trays are detachably mounted on the work platform, with each product tray measuring 20cm in length and 5cm in width.

[0027] In some embodiments of this application, a positioning block 11 for positioning the test strip is provided on the product carrier.

[0028] In some embodiments of this application, multiple weight sensors are evenly distributed on the bottom of the product tray to improve the accuracy of weight detection, thereby improving the accuracy of drying detection.

[0029] The gypsum self-leveling floor drying machine of this application can simultaneously dry multiple test strips. A weight sensor on each product tray detects the weight of the test strip in real time and sends the weight information to the controller. The controller determines the drying status based on the weight information. When the mass change of the test strip over 24 hours is ≤1g, it will display that it is dried, at which point the test strip can be removed for subsequent testing. Information such as the number of test strips, drying temperature, and weight of each test strip is displayed on the screen in real time.

[0030] The beneficial effects of this utility model of a gypsum self-leveling oven-dry strength dryer are: it can not only dry multiple test strips at the same time, but also accurately judge the drying status of each test strip, avoiding repeated operations by operators, greatly improving drying efficiency, and effectively improving the accuracy and stability of drying and status judgment, ensuring the effectiveness and accuracy of testing, and reducing testing costs.
