Description

Technical Field

[0001] This utility model relates to the field of liquid silicone foam preparation technology, and in particular to a sieving device for preparing liquid silicone foam. Background Technology

[0002] Liquid silicone foam, also known as liquid silicone foam, is an environmentally friendly material. It is made by mixing silicone and a curing agent in a 1:1 ratio, resulting in excellent elasticity and softness. During use, it does not produce toxic gases or pungent odors, making it safe and environmentally friendly. Foam is a material made from foamed plastic particles. Due to its good weather resistance, corrosion resistance, and flame retardancy, it is highly popular, leading to an increased demand for liquid silicone foam. Currently, in the production of foam using liquid silicone, waste is generated during production, and this waste easily mixes with the finished product. Therefore, during preparation, it is often necessary to separate the liquid silicone foam from impurities.

[0003] However, in existing screening devices, impurities often remain above the screen during screening, causing blockage of the screen holes. This affects the screening speed of liquid silica foam, reducing screening quality and efficiency. The existing devices have relatively insufficient anti-clogging and cleaning capabilities, failing to effectively screen and filter liquid silica while stably removing impurities clogging the filter plate. Furthermore, during filtration, liquid silica is usually screened by gravity, and when its viscosity is high, the feeding speed is insufficient, resulting in poor pressurized feeding capacity within the tank and reduced screening quality. Therefore, we propose a screening device for the preparation of liquid silica foam to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a sieving device for preparing liquid silicone foam.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The two cleaning anti-clogging plates and the two scraping anti-sticking plates are attached to the upper and lower sides of the filter screen layer.

[0011] Preferably, the top of the drive column penetrates the filter tank and is connected to the output end of the drive motor, the bottom of the drive column is rotatably connected to the bottom of the filter screen layer, and the inner wall cleaning assembly is installed on the drive column.

[0012] Preferably, the sealed hopper is provided with a sealing cover plate at the top, the filter tank is provided with a pressurized installation end on the side, and the output end of the pressurized air blowing assembly is assembled and installed on the pressurized installation end.

[0013] Preferably, the filter tank is provided with a pressure detector and a controller, the output end of the pressure detector is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the drive motor and the pressurized air blowing assembly.

[0014] Preferably, the inner wall cleaning assembly includes two mounting frames and two cleaning scrapers. The mounting frames are fixedly mounted on the anti-clogging brush assembly.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. This sieving device for preparing liquid silica gel foam features a filter screen layer and an anti-clogging brush assembly inside the filter tank. The filter screen layer separates impurities from the liquid silica gel. Impurities and viscous substances easily clog the filter screen layer.

[0028] Please see Figures 1-5 A sieving device for preparing liquid silicone foam includes a filter tank 1, the filter tank 1 having a filter sieve layer 2 and an anti-clogging brush assembly 3 inside;

[0029] A sealed hopper 4 is provided on the side of the top of the filter tank 1. A drive motor 5 is provided at the center of the top of the filter tank 1 to drive the anti-clogging brush assembly 3 to rotate. A pressurizing air blowing assembly 6 is provided on the side of the filter tank 1 to pressurize the upper part of the filter tank 1.

[0030] Among them, the anti-clogging brush assembly 3 is equipped with an inner wall cleaning assembly 7;

[0031] The beneficial effects of this solution are as follows: The filter tank 1 is equipped with a filter screen layer 2 and an anti-clogging brush assembly 3. The filter screen layer 2 can separate impurities from the liquid silica gel. The filtered impurities and viscous substances easily clog the filter screen layer 2. The drive motor 5 can drive the anti-clogging brush assembly 3 to rotate, cleaning and scraping away the adhesive residue remaining on the upper and lower sides of the filter screen layer 2. Simultaneously, it drives the inner wall cleaning assembly 7 to rotate and clean and scrape the inner walls of the upper and lower sides of the filter tank 1, reducing the difficulty of tank cleaning and making it convenient to use. A pressurized air blowing assembly 6 is correspondingly provided on the side of the filter tank 1. The pressurized air blowing assembly 6 pressurizes the upper part of the inner side of the filter tank 1, accelerating the filtration speed of the liquid silica gel. The sealed hopper 4 acts as a seal, increasing the filtration and screening speed of the liquid silica gel under pressure. This results in good anti-clogging cleaning of the filter plates and good self-cleaning effect of the tank, leading to high filtration quality. Furthermore, the pressurized filtration method increases the filtration speed and provides excellent filtration and discharge efficiency.

[0032] Furthermore, the filter tank 1 is a circular tank with a conical bottom. The filter tank 1 is divided into a filter chamber and a discharge chamber by the filter screen layer 2. The output end of the pressurized air blowing assembly 6 is connected to the filter chamber.

[0033] Specifically, the filter tank 1 is a circular tank, which facilitates cleaning and scraping by the anti-clogging brush assembly 3 and the inner wall cleaning assembly 7. The filter tank 1 is divided into a filter chamber and a discharge chamber by the filter screen layer 2. The liquid silica gel is filtered and screened by the filter screen layer 2 in the filter chamber and then filtered into the discharge chamber to complete the impurity screening. The pressurized air blowing assembly 6 pressurizes the filter chamber, which improves the discharge rate and convenience of the liquid silica gel.

[0034] Furthermore, the anti-clogging brush assembly 3 includes a drive column 31, two cleaning anti-clogging plates 32 and two scraping anti-sticking plates 33. The drive column 31 is rotatably connected to the inside of the filter tank 1. The two cleaning anti-clogging plates 32 and the two scraping anti-sticking plates 33 are all fixedly installed on the side of the drive column 31. The two cleaning anti-clogging plates 32 and the two scraping anti-sticking plates 33 are all attached to the upper and lower sides of the filter screen layer 2.

[0035] Specifically, after the drive column 31 rotates, it can simultaneously drive two cleaning and anti-clogging plates 32 and two scraping and anti-sticking plates 33 for cleaning. After being driven, the two cleaning and anti-clogging plates 32 can stably clean the upper and lower sides of the filter screen layer 2, preventing impurities and adhesives from clogging the filter screen. The scraping and anti-sticking plates 33 are driven to scrape and prevent material from sticking to the upper and lower sides of the filter screen layer 2. The cleaning effect of preventing clogging of the filter screen is good, which improves the filtration efficiency and quality.

[0036] Furthermore, the top of the drive column 31 penetrates the filter tank 1 and is connected to the output end of the drive motor 5, the bottom of the drive column 31 is rotatably connected to the bottom of the filter screen layer 2, and the inner wall cleaning component 7 is installed on the drive column 31.

[0037] Specifically, the drive column 31 is rotatably connected to the filter tank 1 and the filter screen layer 2, providing stable rotational support. The drive column 31 can drive the drive motor 5 to rotate, ensuring stable rotation and stable adaptation.

[0038] Furthermore, the top of the sealed hopper 4 is provided with a sealing cover plate 41, and the side of the filter tank 1 is provided with a pressurized installation end 61. The output end of the pressurized air blowing assembly 6 is assembled and installed on the pressurized installation end 61.

[0039] Specifically, the sealing cover 41 acts as a sealing cover for the sealed hopper 4, and the two are stably and conveniently installed. The pressurized installation end 61 is used to connect to the filter tank 1, which facilitates the installation and fixing of the output end of the pressurized air blowing assembly 6, and the installation is convenient.

[0040] Furthermore, a pressure detector 62 and a controller 63 are correspondingly provided on the filter tank 1. The output end of the pressure detector 62 is electrically connected to the input end of the controller 63, and the output end of the controller 63 is electrically connected to the input end of the drive motor 5 and the pressurized air blowing assembly 6.

[0041] Specifically, the pressure detector 62 can detect the pressure in the upper part of the inner side of the filter tank 1, and the controller 63 can control both the drive motor 5 and the pressurized air blowing assembly 6. The switching control is convenient and has excellent adaptability.

[0042] Furthermore, the inner wall cleaning component 7 includes two mounting frames 71 and two cleaning scrapers 72. The mounting frames 71 are fixedly mounted on the anti-clogging brush assembly 3. The side of the mounting frame 71 away from the anti-clogging brush assembly 3 is connected to the cleaning scraper 72. Both cleaning scrapers 72 are matched and abut against the inner wall of the filter tank 1. The two cleaning scrapers 72 are respectively set on the upper and lower sides of the filter screen layer 2.

[0043] Specifically, the two mounting brackets 71 are used to install the two cleaning scrapers 72 on the anti-clogging brush assembly 3. The installation is well compatible. When the anti-clogging brush assembly 3 rotates, it can drive the cleaning scrapers 72. The cleaning scrapers 72 can clean the inner wall of the filter tank 1, making it easy to scrape off the residue on the inner wall of the tank. The self-cleaning effect is good.

[0044] Furthermore, a rubber anti-wear strip 73 is provided on the side of the cleaning scraper 72 away from the mounting frame 71, and the rubber anti-wear strip 73 is attached to and abuts against the inner wall of the filter tank 1.

[0045] Specifically, the rubber anti-wear strip 73 has an anti-wear and scraping effect, which makes the can body self-cleaning and prevents residue, and is not easy to damage the inner wall of the can, resulting in good performance.

[0046] How to use and how to work this device:

[0047] By installing a filter screen layer 2 and an anti-clogging brush assembly 3 inside the filter tank 1, the filter screen layer 2 can screen and filter liquid silica gel, removing impurities from the liquid silica gel to facilitate subsequent production. During the filtration process, impurities and viscous substances in the liquid silica gel can easily clog the filter screen layer 2. The drive motor 5 can drive the anti-clogging brush assembly 3 to rotate. The anti-clogging brush assembly 3 includes a drive column 31, two cleaning anti-clogging plates 32, and two scraping anti-sticking plates 33. After the drive column 31 rotates, it can simultaneously drive the two cleaning anti-clogging plates 32 and the two scraping anti-sticking plates 33 to clean. After being driven, the two cleaning anti-clogging plates 32 can stably clean both the upper and lower sides of the filter screen layer 2, preventing impurities and adhesives from clogging the filter plates. The scraping anti-sticking plates 33 are driven to scrape and prevent sticking on both the upper and lower sides of the filter screen layer 2, resulting in a better anti-clogging and cleaning effect on the filter plates, improving filtration efficiency and quality.

[0048] When the anti-clogging brush assembly 3 is driven, it can simultaneously drive the inner wall cleaning assembly 7, so that the inner wall cleaning assembly 7 rotates to clean and scrape the upper and lower inner walls of the filter tank 1. This makes it difficult for the liquid silica gel to stick to the inside of the tank after filtration and screening, making cleaning convenient and greatly reducing the difficulty of cleaning the tank later.

[0049] A pressurized air blowing assembly 6 is provided on the side of the filter tank 1. When liquid silica gel enters the filter tank 1, it is filtered and cleaned by the filter screen layer 2. Then, the pressurized air blowing assembly 6 pressurizes the upper part of the inner side of the filter tank 1, increasing the air pressure in the upper part of the tank, thereby accelerating the filtration speed of the liquid silica gel. The liquid silica gel enters the filter tank 1 through the sealed hopper 4. The sealed hopper 4 acts as a seal, and the liquid silica gel is subjected to pressure, which increases the filtration screening speed, resulting in high filtration efficiency. This also ensures good anti-clogging and cleaning of the filter plates and good self-cleaning effect of the tank, resulting in high filtration quality. Furthermore, the pressurized filtration method increases the filtration speed and provides excellent filtration discharge efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
