Description

Technical Field

[0001] This utility model relates to the technical field of silica sol coating processing equipment, and in particular to a filtration device for silica sol coating processing. Background Technology

[0002] Silica sol is a colloidal solution, odorless and non-toxic. It is a dispersion of nano-sized silica particles in water or a solvent. There are different methods for preparing silica sol. The most common methods include ion exchange, one-step hydrolysis of silica powder, and silane hydrolysis. Filtration devices are often used in the processing of silica sol coatings. During the production of silica sol, the liquid may contain particulate matter, metal ions, organic impurities, and small molecular weight impurities. These impurities can easily affect the quality of subsequent silica sol products. However, most existing filtration methods rely on static settling, which is time-consuming, inefficient, and ineffective at separating various impurities. Utility Model Content

[0003] In view of this, the present invention provides a filtration device for processing silica sol coatings, which can filter various impurities in silica sol liquid and also level the silica sol liquid, thereby improving the filtration effect and efficiency of silica sol liquid.

[0004] The technical solution is: a filtration device for processing silica sol coatings, comprising a base frame, a housing, a feed hopper, a feed pipe, a filter component, and an evaporation component. The housing is mounted on the base frame, with a discharge port at the bottom and a feed hopper at the top, which is connected to the interior of the housing. A feed pipe is also mounted at the top of the housing, which is connected to the interior of the housing. The filter component and the evaporation component are both located inside the housing.

[0005] Furthermore, the filtration components include a fixed frame, fixed plates, filter membranes, activated carbon membranes, ultrafiltration membranes, pulleys, belts, motors, lead screws, limiting rods, sliders, and push plates. The housing contains a fixed frame, and three fixed plates are snapped into it. The filter membrane, activated carbon membrane, and ultrafiltration membrane are respectively mounted on the three fixed plates, arranged from top to bottom. Three pulleys are rotatably connected to one side of the housing, with a belt wound between them. A motor is located on one side of the housing, and its output shaft is fixedly connected to one of the pulleys. Three lead screws are rotatably connected inside the housing, and these lead screws are fixedly connected to the pulleys. Several limiting rods are located inside the housing, with two limiting rods on the same horizontal plane forming a group. A slider is slidably connected between the two limiting rods in each group, and the slider is threaded to the lead screw. Push plates are located at the bottom of each of the three sliders, and these three push plates contact the filter membrane, activated carbon membrane, and ultrafiltration membrane respectively.

[0006] Furthermore, the evaporation component includes a heating plate, an electric push rod, a pusher, a heater, and an exhaust pipe. The chamber is equipped with two heating plates inside and two electric push rods on the chamber. Each of the two electric push rods has a pusher on its extension rod, and the pusher contacts the heating plate. The chamber is also equipped with two heaters inside, which are fixedly connected to the heating plates. The fixed frame has air holes, and the chamber is equipped with an exhaust pipe that contacts the air holes of the fixed frame.

[0007] The beneficial effects are as follows: First, silica sol solution is manually poured into the feed hopper and an appropriate amount of chelating agent is poured into the feed pipe. The motor, two electric push rods, and two heaters are then started. Three push plates continuously level the silica sol solution that falls onto the filter membrane, activated carbon membrane, and ultrafiltration membrane. The filter membrane filters out larger particles in the silica sol solution. The chelating agent removes metal ions from the silica sol solution and leaves the binding products on the filter membrane, activated carbon membrane, and ultrafiltration membrane. The activated carbon membrane filters out organic impurities in the silica sol solution, and the ultrafiltration membrane filters out the silica sol solution. To remove smaller molecular weight impurities, two heaters heat the silica sol solution. Volatile organic impurities in the silica sol solution are carried in the vapor and flow out along the outlet pipe. This process filters various impurities in the silica sol solution and also levels the silica sol solution on the filter membrane, activated carbon membrane, and ultrafiltration membrane, making the filtration more uniform. Furthermore, heating the filtered silica sol solution allows for the separation of volatile organic impurities, improving the filtration effect and efficiency of the silica sol solution.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Example 1: A filtration device for processing silica sol coatings, such as... Figure 1-Figure 3As shown, it includes a base frame, a housing, a feed hopper, a feed pipe, a filter component, and an evaporation component. The housing is welded to the base frame, and a discharge port is opened at the bottom of the housing. The feed hopper is connected to the top of the housing by rivets, and a cover plate is snapped onto the feed hopper. The feed hopper communicates with the inside of the housing. The feed pipe is connected to the top of the housing by a flange, and an end cap is snapped onto the feed pipe. The feed pipe communicates with the inside of the housing. The filter component and the evaporation component are located inside the housing.

[0014] Furthermore, the filtration components include a fixed frame, fixed plates, filter membranes, activated carbon membranes, ultrafiltration membranes, pulleys, belts, motors, lead screws, limiting rods, sliders, and push plates. A fixed frame is welded inside the housing, and three fixed plates are snapped into the housing. The filter membrane, activated carbon membrane, and ultrafiltration membrane are respectively mounted on the three fixed plates, arranged from top to bottom. Three pulleys are rotatably connected to one side of the housing, with a belt wound between them. A motor is welded to one side of the housing, and the motor's output shaft is fixedly connected to one of the pulleys. Three lead screws are rotatably connected inside the housing, and the lead screws are fixedly connected to the pulleys. Several limiting rods are provided inside the housing; two limiting rods on the same horizontal plane form a group, and a slider is slidably connected between the two limiting rods in each group. The slider is threadedly connected to the lead screw. Push plates are provided at the bottom of each of the three sliders, and the three push plates contact the filter membrane, activated carbon membrane, and ultrafiltration membrane respectively.

[0015] Furthermore, the evaporation component includes a heating plate, an electric push rod, a pusher, a heater, and an exhaust pipe. Inside the housing, two heating plates are bolted together. Two electric push rods are welded onto the housing. Each of the two electric push rods has a pusher on its extension rod, and the pusher contacts the heating plate. Inside the housing, two heaters are bolted together and fixedly connected to the heating plate. The fixed frame has air holes. An exhaust pipe is provided on the housing, and the exhaust pipe contacts the air holes of the fixed frame.

[0016] First, manually remove the cover plate on the feed hopper and the end cap on the feed pipe. Then, manually pour silica sol into the feed hopper and an appropriate amount of chelating agent into the feed pipe. Next, manually start the motor, two electric push rods, and two heaters. Then, reconnect the cover plate on the feed hopper and the end cap on the feed pipe. The motor's output shaft drives one pulley to reciprocate, which in turn drives the belt and two other pulleys to reciprocate. These three pulleys drive three lead screws to reciprocate, which in turn drives three sliders and three push plates to move back and forth. The plates contact the filter membrane, activated carbon membrane, and ultrafiltration membrane respectively. Three pusher plates continuously flatten the silica sol solution that falls onto these membranes. The filter membrane filters out larger particles from the silica sol solution, while the chelating agent removes metal ions and leaves the binding products on the filter, activated carbon, and ultrafiltration membranes. The activated carbon membrane filters out organic impurities, and the ultrafiltration membrane filters out smaller molecular weight impurities. The filtered silica sol solution falls onto two heating plates, where two heaters heat the solution. Volatile organic impurities will be mixed in with the vapor and flow out along the outlet pipe. After evaporation for a period of time, the telescopic rods of the two electric push rods will extend successively. The telescopic rods of the electric push rods will drive the two push frames to move closer to each other. The upper push frame will push the silica sol liquid on the upper heating plate to the lower heating plate, and the lower push frame will push the silica sol liquid on the lower heating plate out, so that the silica sol liquid flows out along the discharge port of the box. Then, the motor, the two electric push rods, and the two heaters will be manually turned off. The telescopic rods of the two electric push rods will retract, and the extension of the electric push rods will... The retracting rod moves the two pushers away from each other. Then, the three fixing plates are manually removed to clean the impurities on the filter membrane, activated carbon membrane, and ultrafiltration membrane. After cleaning, the three fixing plates are reattached. This process is repeated to filter various impurities in the silica sol solution. It can also level the silica sol solution on the filter membrane, activated carbon membrane, and ultrafiltration membrane, making the filtration more uniform. Furthermore, the filtered silica sol solution can be heated to separate volatile organic impurities, thereby improving the filtration effect and efficiency of the silica sol solution.

[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
