Description

Technical Field

[0001] This utility model relates to the field of aerogel material preparation technology, specifically to an aerogel coating preparation device. Background Technology

[0002] Aerogel is a novel material with a nanoporous network structure, characterized by extremely low density, high specific surface area, excellent thermal insulation performance, and good adsorption properties. It has broad application prospects in aerospace, building energy conservation, and heat dissipation of electronic devices. However, the preparation of aerogel materials requires multiple processes, such as sol-geling and drying. To ensure the sol-geling effect of aerogel, it is particularly important to develop an aerogel coating preparation device.

[0003] A device for preparing an aqueous nano-aerogel thermal insulation and damping coating, referenced in announcement number CN213824284U, includes a tank containing a coating scraping mechanism. The coating scraping mechanism comprises an inner support frame in a ring shape and a cylinder. The cylinder is fixed to the top outer wall of the tank. The inner support frame is located inside the tank, and its inner wall is connected to a telescopic rod extending into the tank from the cylinder for vertical movement. Multiple scraper assemblies are arranged in a ring around the center of the inner support frame on its outer side. This device, by installing coating scraping components inside the tank, can scrape off residual coating on the inner wall of the tank after discharge, avoiding resource waste caused by residual coating adhering to the inner wall and being unable to be collected. However, while this device can be applied effectively, it is generally not convenient for circulating and transporting the coating at the bottom of the tank, leading to sedimentation and affecting the preparation effect of the aerogel material. Further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an aerogel coating preparation device to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to circulate and transport the coating at the bottom of the tank, which makes the coating prone to sedimentation at the bottom of the tank, thus affecting the preparation effect of aerogel materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aerogel coating preparation device, comprising a U-shaped frame, a base fixedly installed at the top of the U-shaped frame, a support seat bolted to one side of the top of the base, a preparation tank at the top of the support seat, a tank opening on one side of the top of the preparation tank, a first motor installed at the center of the top of the preparation tank, a stirring shaft at the center of the inside of the preparation tank, the top of the stirring shaft extending to the outside of the preparation tank and connected to the bottom of the first motor, stirring blades installed at the bottom of the stirring shaft, a circulation pump installed at the top of the base on one side of the support seat, a first pump pipe installed at one end of the circulation pump, the end of the first pump pipe away from the circulation pump extending to the bottom of the preparation tank, a second pump pipe installed at the other end of the circulation pump, the end of the second pump pipe away from the circulation pump communicating with the outer wall of the upper end of the preparation tank, a stand provided on one side of the bottom of the U-shaped frame, a control panel installed at the top of the stand, and the output terminal of the microcontroller inside the control panel electrically connected to the input terminal of the first motor and the circulation pump respectively.

[0007] Preferably, connecting rods are provided on both outer walls of the upper end of the stirring shaft, and a scraper is installed on the end of the connecting rod away from the stirring shaft. The outer wall of the scraper contacts the inner wall of the preparation tank. The scraper is designed to scrape and clean the inner wall of the preparation tank.

[0008] Preferably, a discharge body is provided on one side of the bottom end of the base, and a valve pipe is provided at the center of the top of the discharge body. The top end of the valve pipe is connected to the bottom end of the preparation tank. The valve pipe is provided to discharge the aerogel material inside the preparation tank.

[0009] Preferably, two collection boxes are installed at the bottom of the U-shaped frame below the discharge machine body, a rotating shaft is rotatably installed on the inner wall of the discharge machine body, and a limiting plate is installed on the outer wall of the rotating shaft.

[0010] Preferably, a second motor is installed on the surface of the discharge machine body. The input end of the second motor is electrically connected to the output end of the microcontroller inside the control panel. One end of the second motor extends into the interior of the discharge machine body and is connected to one end of the rotating shaft. The second motor is configured to drive the limiting plate to rotate via the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the aerogel coating preparation device not only ensures the preparation effect of aerogel coating when the preparation device is used, but also reduces the phenomenon of aerogel coating adhering to the inner wall of the preparation tank, and achieves the purpose of easy dual-station feeding and collection of aerogel coating.

[0012] (1) By starting the circulation pump, the aerogel coating at the bottom of the preparation tank is transported to the upper part of the preparation tank through the second pump pipe via the first pump pipe. The aerogel coating inside the preparation tank is stirred in a circulating manner, which can effectively reduce the phenomenon of sedimentation of the aerogel coating at the bottom of the preparation tank, thereby ensuring the preparation effect of the aerogel coating when the preparation device is used.

[0014] (3) By opening the valve on the outer wall of the valve tube, the aerogel coating inside the preparation tank falls into the discharge machine body through the valve tube. Due to the setting of the second motor, the limiting plate is driven by the rotating shaft to rotate slightly inside the discharge machine body. When the top of the limiting plate abuts against the inner wall of the left side of the discharge machine body, the aerogel coating is discharged into the collection box on the right side through the opening on the right side of the bottom of the discharge machine body. When the top of the limiting plate abuts against the inner wall of the right side of the discharge machine body, the aerogel coating is discharged into the collection box on the left side through the opening on the left side of the bottom of the discharge machine body. This achieves the purpose of easy dual-station feeding and collection of aerogel coating. Attached Figure Description
