Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to an intelligent temperature and humidity control system for cement-based materials. Background Technology

[0002] High-temperature heating and drying devices are widely used in chemical laboratories of universities and research institutes. During drying operations, limitations in experimental conditions prevent cement-based materials from being dried at the predetermined temperature and humidity within a set timeframe. This leads to inaccurate observation of the material's state data, causing errors in experimental analysis. Heating experimental materials by burning typically produces fumes and other harmful gases, affecting the laboratory environment and posing risks to personnel. Furthermore, the material carrier is not easily secured during burning, making it prone to slipping and causing burns. In addition, high-temperature heating and drying devices in laboratories are usually separate devices, resulting in high operating costs and significant space consumption. Utility Model Content

Detailed Implementation

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0025] refer to Figure 3 and Figure 4 This utility model provides an intelligent temperature and humidity control system for cement-based materials, including: a box 1 and a fixing frame 2, a heating net 3 and a support net 4 installed inside the box 1.

[0026] The chamber 1 has a rectangular structure and a hollow interior, including an inner partition and an outer panel. The inner wall of the outer panel is lined with an insulation layer to prevent heat transfer from the chamber 1 outwards, thus avoiding burns to personnel. The inner wall of the inner partition has multiple limiting blocks along its height. Two adjacent rows of limiting blocks are used to control the installation of the mounting bracket 2, heating net 3, or material support net 4. The material support net 4, mounting bracket 2, and heating net 3 are arranged sequentially from top to bottom. When a large amount of experimental material needs to be heated at high temperatures, the material support net 4 can be removed to increase the internal space of the chamber 1. When drying is required, the mounting bracket 2 can be removed, and the material support net 4 can be installed at a lower position to accommodate taller containers or materials.

[0027] As a preferred embodiment, the fixing frame 2 is made of springs interwoven in the horizontal and vertical directions to form a spring net. The experimental container is fixed by clamping the spring net. Not only can the elastic force of the springs be used to fix the experimental container, but multiple experimental containers can also be placed at intervals.

[0028] In a preferred embodiment, the heating mesh 3 is an electric heating wire, which is connected to an electric wire. The electric wire is equipped with a heating switch 13 to control whether the circuit is connected or not.

[0029] As a preferred embodiment, the support net 4 can be made of a high-temperature resistant and thermally stable resin material, such as polyimide resin. Of course, the material can be changed or selected according to the heating temperature.

[0030] The lower part of the heating grid 3 is provided with a lower partition, which separates the space for high-temperature heating or drying from the lower space of the chamber 1 and isolates heat transfer; a timer, a controller and a fan are provided in the lower space of the chamber 1. The timer is used to set the experimental time, and the fan is used to blow the flue gas generated in the chamber 1 into the collection container. The timer and the fan are respectively connected to the controller.

[0031] In addition, a temperature and humidity sensor is installed on the inner side of the inner partition of chamber 1 to monitor the internal temperature and humidity of the chamber during high-temperature experiments or drying.

[0032] The outer side panel of the enclosure 1 is equipped with a temperature display screen 9, a time display screen 10, a power switch 11, a timer switch 12, a heating switch 13, and a ventilation switch 14. The temperature display screen 9 is communicatively connected to a temperature and humidity sensor, and can display the real-time temperature data detected by the thermometer. The time display screen 10 is electrically connected to a timer, and can display the duration of the experiment and perform timing functions. The timer switch 12 is located on the side of the time display screen 10, and can be used to set the timer. The humidity display screen 16 is electrically connected to the timer, and can display the experimental humidity. The power switch 11 is located on the main circuit and is used to control whether each circuit is powered on or off.

[0033] Furthermore, the design of the pre-set intelligent temperature and humidity control system, combined with the actual needs of temperature and humidity control within the enclosure, is based on an Internet of Things (IoT) architecture. The system is designed holistically, with detailed designs for IoT sensing terminals, transmission terminals, and control terminals. This enables temperature and humidity control within the enclosure for preset time periods. The temperature and humidity control can be divided into up to three stages, each with customizable time, temperature, and humidity settings. The time setting range is 0-8 hours, the temperature setting range is 10-100℃, and the humidity setting range is 20%RH-80%RH. The temperature and humidity control procedure flow is referenced below.

[0034] Ventilation holes 5 are provided on the inner partition of the box 1, and ventilation openings 6 are provided on the outer top plate of the box 1. The ventilation holes 5 and ventilation openings 6 are connected to each other and are used to exhaust the fumes generated during the experiment. A fume collection container or a pipe can be connected to the ventilation openings 6 to centrally discharge and treat toxic and harmful fumes.

[0035] A sliding baffle 8 is provided on the frame of the chamber 1. The chamber 1 can be closed or opened by sliding the baffle 8. The sliding baffle 8 can be slid up and down through the groove connected to the frame of the chamber 1. Preferably, the sliding baffle 8 is made of high temperature resistant glass. The glass sliding baffle 8 makes it easy for the experimental personnel to observe the situation inside the chamber 1 so as to make accurate judgments.

[0036] The enclosure 1 is equipped with an alarm 7 and a light. The light is located inside the inner partition of the enclosure 1. The light can improve the brightness inside the enclosure 1, making it easier for the experimenters to observe and place experimental containers. The alarm 7 is located on the outer wall of the enclosure 1. The alarm 7 is connected to a timer. When the time set on the timer is reached, the alarm 7 will sound to remind the experimenters to check.

[0037] The working principle of this all-in-one machine:

[0038] When conducting high-temperature heating experiments or drying experimental materials, fix the experimental container to the spring mesh or place it on the support mesh 4, turn on the power switch 11, then turn on the timer switch 12, set the heating or drying time through the time display screen 10, and close the chamber 1 through the push-pull baffle 8; turn on the heating switch 13, the heating mesh 3 starts heating, and the thermometer displays the temperature inside the chamber 1 through the temperature display screen 9; after the timer reaches the set time, the alarm 7 reminds personnel to check. For experimental materials that produce gas, the ventilation switch 14 needs to be turned on during the heating or drying process to make the fan work and exhaust the gas through the vent 6.
