Description

Technical Field

[0001] This utility model relates to the field of industrial storage equipment, and in particular to a moisture-proof cabinet for abrasive materials. Background Technology

[0002] Abrasive materials are functional materials composed of high-hardness particles and binders, widely used in machining, precision manufacturing, and other fields. Their performance is directly affected by ambient humidity, especially during storage. If the humidity is too high, the binder in the abrasive material easily absorbs moisture and softens, leading to a decrease in material structural strength, abrasive grain shedding, or agglomeration and failure. Therefore, the relative humidity of the storage environment for abrasive materials must be strictly controlled to maintain their grinding efficiency and stability.

[0003] Currently, the drying process for abrasive materials mainly relies on high-temperature baking technology. The specific method involves placing the damp abrasive material in an electric oven or infrared heating device and heat-treating it for several hours to over ten hours at a temperature range of 80-150℃ to remove moisture through evaporation. However, this method requires heating the entire material, which is not only energy-intensive but also has limited temperature control precision. For example, for abrasive materials containing organic resin binders, if the temperature exceeds their glass transition temperature, the binder may soften or oxidize, thereby damaging the material structure; while insufficient temperature cannot effectively remove deep moisture, resulting in incomplete drying.

[0004] The temperature control of existing drying technologies relies on manual experience or simple temperature control devices, which makes it difficult to dynamically adapt to the temperature resistance threshold of different grinding materials, easily causing thermal damage to the materials or low drying efficiency. Secondly, long-term high-temperature operation leads to energy waste, especially in batch processing, where the equipment has high thermal inertia and high heat dissipation loss, which does not conform to the trend of green manufacturing. Thirdly, repeated heating and cooling processes aggravate equipment wear and tear. Utility Model Content

[0005] To overcome the drawbacks of poor temperature control and high energy consumption, this utility model provides a moisture-proof cabinet for abrasive materials, aiming to solve the above-mentioned shortcomings.

[0006] A moisture-proof cabinet for grinding materials includes a cabinet body with several storage layers connected inside. A cover plate is connected to the front side of the cabinet body and is connected to the front end of all the storage layers, thus closing the cabinet body. Two sealing doors are rotatably connected to the front side of the cabinet body. A controller is installed on the cover plate, and pressure relief valves are provided at the top and bottom of the cover plate. A mounting bracket is connected to the left side of the cabinet body, and a blower is installed on the mounting bracket. One end of an air guide hood is connected to the left side of the cabinet body, and the other end is connected to the air outlet of the blower. A heating element is installed inside the air guide hood. An air outlet is opened at the bottom left side of the cabinet body. A gas diversion component is installed inside the cabinet body. A temperature sensor is installed at the connection between the cabinet body and the heating element. The blower, heating element, and temperature sensor are all wired to the controller. A gas circulation component is provided on the left side of the cabinet body.

[0007] In one embodiment, the air diversion assembly includes a second diversion plate. The placement layers are separated from each other, thereby forming crisscrossing air outlet channels between the placement layers, thus forming branching channels. A first diversion plate is connected inside the cabinet and is located between two longitudinally adjacent rows of placement layers. The second diversion plate is connected to the outside of the placement layers. Airflow to each branching point is diverted through the first diversion plate and the second diversion plate.

[0008] In one embodiment, the circulation component includes a collecting hood, a protective cover connected to the left side of the cabinet, an exhaust hood connected to the upper left side of the cabinet, and notches on the protective cover above and behind the exhaust hood. The blower has an air inlet, and the exhaust hood is connected to the air inlet. A collecting hood is connected to the air outlet at the bottom of the cabinet. A first air duct is connected to the left end of the collecting hood, and a control valve is provided at the left end of the collecting hood. One end of a second air duct is connected to the left end of the collecting hood, and the control valve controls the gas flowing out of the collecting hood to enter the first air duct or the second air duct. The other end of the second air duct is connected to the exhaust hood, and the end of the first air duct passes through the protective cover. The protective cover covers the left side component of the cabinet.

[0009] In one embodiment, a plurality of stabilizing frames are connected to the left side of the cabinet, and the stabilizing frames are fitted onto the second air duct.

[0010] In one embodiment, a plurality of identification cards are affixed to the cover plate, and the identification cards are all located above the placement layer.

[0011] In one embodiment, the sealed door has a transparent observation window in the middle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The airflow temperature is monitored in real time by a temperature sensor and the data is fed back to the controller. The controller dynamically adjusts the power output of the heating tube to control the temperature inside the cabinet. The airflow distribution is optimized by the flow distribution component to ensure the temperature uniformity of each layer and improve the drying quality of the grinding material.

[0014] 2. A closed hot air circulation path is formed by the circulation component, so that the heated air is circulated multiple times in the cabinet, reducing heat loss. The control valve switches the airflow path, so that some of the hot air flows back to the blower inlet through the second air duct, reducing the continuous energy consumption of the heating tube and achieving the purpose of saving energy.

[0015] 3. The heat insulation design of the protective cover reduces heat loss, further optimizes energy utilization, and ultimately achieves a highly efficient and energy-saving drying process. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example: A moisture-proof cabinet for abrasive materials, such as Figures 1-4As shown, the system includes a cabinet 1, a cover plate 101, a sealing door 102, a pressure relief valve 103, a controller 104, a mounting bracket 2, a blower 3, an air guide hood 4, a heating element 401, placement layers 5, a flow distribution assembly, a temperature sensor 10, and a circulation assembly. Several placement layers 5 are connected inside the cabinet 1. The front of the cabinet 1 is connected to the cover plate 101, which is connected to the front ends of all placement layers 5, thus sealing the cabinet 1. Two sealing doors 102 are rotatably connected to the front of the cabinet 1. The controller 104 is mounted on the cover plate 101. Pressure relief valves 103 are installed at both the top and bottom of the cover plate 101. The cabinet 1 forms a sealed space, and the sealing door 102 at the front is airtightly closed by a silicone sealing strip. The pressure relief valve 103 can automatically adjust the internal and external pressure difference. A mounting bracket 2 is connected to the left side of the cabinet 1. A blower 3 is installed on the mounting bracket 2. One end of the air guide hood 4 is connected to the left side of the cabinet 1, and the other end is connected to the air outlet of the blower 3. The blower 3 drives the airflow. The heating tube 401 provides a controllable heat source. The air guide hood 4 guides the airflow to enter the cabinet 1 evenly. The heating tube 401 is installed inside the air guide hood 4. An air outlet 9 is opened at the bottom left side of the cabinet 1. A gas diversion component is installed inside the cabinet 1. A temperature sensor 10 is installed at the connection between the cabinet 1 and the heating tube 401. The blower 3, the heating tube 401 and the temperature sensor 10 are all wired to the controller 104. A gas circulation component is installed on the left side of the cabinet 1.

[0024] like Figures 2-4 As shown, the air diversion assembly includes a first diversion plate 6 and a second diversion plate 7. The placement layers 5 are separated from each other, thus forming a crisscrossing air outlet channel 8 between the placement layers 5, thereby forming a branching channel. The first diversion plate 6 is connected inside the cabinet 1 and is located between two adjacent rows of placement layers 5 in the longitudinal direction. The second diversion plate 7 is connected to the outside of the placement layers 5. When the airflow reaches each branching point, it is diverted through the first diversion plate 6 and the second diversion plate 7. The first diversion plate 6 and the second diversion plate 7 guide the airflow to flow in layers and optimize the air path distribution.

[0025] like Figure 2 , Figure 4 and Figure 5As shown, the circulation assembly includes an air collecting hood 11, a first air duct 1101, a control valve 1102, a second air duct 12, an exhaust hood 13, and a protective cover 17. The protective cover 17 is connected to the left side of the cabinet 1, and the exhaust hood 13 is connected to the upper left side of the cabinet 1. The protective cover 17 has openings above and behind the exhaust hood 13. The blower 3 has an air inlet 301, and the exhaust hood 13 communicates with the air inlet 301. The air collecting hood 11 is connected to the air outlet 9 at the bottom of the cabinet 1. The first air duct 1101 is connected to the left end of the air collecting hood 11, and the control valve 1102 is installed at the left end of the air collecting hood 11. One end of the second air duct 12 communicates with the left end of the air collecting hood 11. The control valve 1102 controls the gas flowing out of the air collecting hood 11 to enter the first air duct 1101 or the second air duct 12. The temperature sensor 10 monitors in real time, the controller 104 dynamically adjusts the power of the heating tube 401, and the control valve 1102 switches the airflow path to avoid energy waste. At the same time, it supports the recycling of hot air and reduces energy consumption. The waste heat collected by the air collecting hood 11 flows back to the system through the second air duct 12, which significantly improves the heat energy recovery rate. The other end of the second air duct 12 is connected to the exhaust hood 13. The end of the first air duct 1101 passes through the protective cover 17, which covers the blower 3, the air guide hood 4 and other components on the left side of the cabinet 1.

[0026] like Figure 2 As shown, it also includes a stabilizer 14. Several stabilizers 14 are connected to the left side of the cabinet 1. The stabilizers 14 are fitted onto the second air duct 12. The stabilizers 14 reduce vibration and improve the ease of operation and safety.

[0027] like Figure 1 As shown, it also includes identification cards 15. Several identification cards 15 are pasted on the cover plate 101. The identification cards 15 are all located above the placement layer 5. The identification cards 15 guide the layered placement of materials.

[0028] like Figure 1 As shown, it also includes an observation window 16. A transparent observation window 16 is provided in the middle of the sealed door 102, which facilitates monitoring.

[0029] Workers place the grinding materials requiring drying and storage in the storage layer 5, according to the required drying temperature and time; the higher up the layer, the greater the drying requirement. Placement is indicated by identification cards 15. Then, the sealing door 102 is closed, and the blower 3 and heating element 401 are activated via controller 104. The blower 3 draws air through the air inlet 301, and the airflow is heated as it passes through the heating element 401. The hot airflow enters the cabinet 1 through the air guide hood 4, and then flows along the air outlet 8, enveloping the storage layer 5. As it passes through the branching point… The airflow is split by the first diverter plate 6 and the second diverter plate 7, ensuring that the airflow fills the cabinet 1. In the initial stage, the control valve 1102 closes the connection between the air collector hood 11 and the second air duct 12. After an interval of 5-10 seconds, the control valve 1102 is opened, and the gas discharged from the air collector hood 11 is guided into the second air duct 12 through the control valve 1102. The gas then flows upward along the second air duct 12 into the exhaust hood 13. Thus, the gas entering the air inlet 301 is mostly the gas discharged from the second air duct 12. The temperature sensor 10 detects the temperature of the incoming airflow. The heated airflow is reheated through the heating tube 401. If the temperature exceeds the threshold set by the temperature sensor 10, the temperature sensor 10 sends a high-temperature signal to the controller 104, shutting off or adjusting the power of the heating tube 401, thereby saving energy. The protective cover 17 that seals the second air duct 12 reduces contact between the external airflow and the second air duct 12, ensuring the airflow temperature and further guaranteeing the reuse effect of the hot airflow. The hot airflow dries the placement layer 5 and the grinding material placed inside. The moisture in the airflow is discharged through the pressure relief valve 103. After drying is completed, the valve is closed. Close the blower 3 and heating pipe 401. If it is necessary to remove the grinding material in time, before turning off the blower 3, adjust the connection of the air collecting hood 11 through the control valve 1102 so that the first air pipe 1101 is connected to the air collecting hood 11. The remaining gas is discharged to the outside, reducing the temperature inside the cabinet 1, thus prolonging the gas exchange time and removing the heat inside the cabinet 1. Finally, open the sealing door 102 and take out the grinding material. The observation window 16 is made of glass. When the cabinet 1 is cooled down, water vapor adheres to the glass. Before closing the sealing door 102, wipe the water stains on the inside of the observation window 16 dry.
