Description

Technical Field

[0001] This utility model relates to the field of silicone sealant production equipment, specifically a filtration device for silicone sealant production. Background Technology

[0002] Silicone sealant is a paste-like material that hardens into a tough, rubber-like solid upon contact with moisture in the air. It is mainly classified into acetic acid-free, alcohol-free, ammonia-free, and propylene-free types. Because it is commonly used for bonding and sealing glass, it is commonly known as glass sealant. Single-component silicone glass sealant is a paste-like material that hardens into a tough, rubber-like solid upon contact with moisture in the air. The production process of silicone sealant mainly consists of five steps: raw material preparation, mixing, defoaming, curing, and packaging. During the mixing process, a filtration device is needed to remove impurities and large silicone sealant lumps from the base material, improving the purity and quality of the product.

[0003] Application number CN221207077U discloses a filtration device and apparatus for silicone sealant production, including a collection tank containing a rotatable filter barrel. The filter barrel has a drive mechanism at its end for rotating it, and a removable filter element. The filter element includes a barrel body with a removable end cap on one side. The barrel body contains evenly distributed limiting strips with transverse grooves between them. The filter element has slots corresponding to the limiting strips, and filter holes corresponding to the transverse grooves are located between the slots. Sealing rings are provided at both ends of the filter element. This design allows for easy filter element replacement while minimizing sealant residue.

[0004] Existing technologies utilize a filtration device comprised of a collection tank, a filter tank, and a drive structure to perform filtration. A removable filter element is installed inside the filter tank, allowing silicone sealant to enter and be filtered by the element to remove impurities. Sealing rings at both ends enhance the sealing effect. However, during operation, silicone sealant can easily accumulate inside the filter element, causing blockages and making cleaning difficult. Furthermore, the natural flow of silicone sealant results in slow filtration efficiency and an inability to quickly achieve the desired filtration effect. Therefore, we propose a filtration device for silicone sealant production to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for silicone sealant production, which solves the problems of existing filtration devices being prone to clogging of internal filter components during use, making cleaning inconvenient, and having slow filtration and discharge efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a filtration device for silicone sealant production, comprising a coarse filtration structure. The coarse filtration structure includes a storage tank, with a first filtration chamber at the bottom of the storage tank. A filter plate is installed inside the first filtration chamber, and connecting parts are provided on both sides of the top of the first filtration chamber. A fine filtration structure is connected to the bottom of the first filtration chamber. The fine filtration structure includes a second filtration chamber, with a precision filter plate and a discharge pipe installed inside the second filtration chamber. A base plate is provided at the bottom of the precision filter plate, and a driving mechanism is connected to the bottom of the precision filter plate. The driving mechanism includes a rotating bracket, with a rotating shaft installed at the center of the rotating bracket. A support seat is sleeved on the outside of the rotating shaft, and a base is installed at the bottom of the rotating shaft for connection.

[0008] The design incorporates a vertically connected coarse and fine filtration structure, which can be quickly assembled and disassembled via connectors. This optimizes the tiered filtration process. The filter plates remove lumps and impurities from the silicone sealant, preventing bottom clogging and reducing the frequency of cleaning, thus improving the filtration efficiency.

[0009] Furthermore, the bottom of the storage hopper is movably connected to the top of the first filter chamber, and a filter plate is movably installed on the top of the first filter chamber. Filter ports are evenly opened on the outside of the filter plate, and mounting holes are opened on both sides of the top of the first filter chamber.

[0010] Furthermore, the connecting column is movably connected to the outside of the mounting hole, a protrusion is fixedly installed at the bottom of the connecting column, and a hook ring is movably sleeved on the top of the connecting column. The protrusion is movably engaged with the second filter chamber in the fine filter structure.

[0011] The precision filter plate is linked to the drive mechanism. The rotating shaft drives the filter plate to filter dynamically, and the discharge pipe discharges the material, which accelerates the flow of silicone resin inside the second filter chamber. This method enables the filtration process to be completed quickly, thereby improving the efficiency of the filtration process.

[0012] Furthermore, grooves are formed at the center of both sides of the top of the second filter chamber, and the grooves are adapted to be connected with the protrusions. Sealing rings are movably fitted on both sides of the outside of the second filter chamber. A precision filter plate is movably installed in the middle of the second filter chamber. Several precision ports are formed on the outside of the precision filter plate. A discharge pipe is fixedly installed at the bottom of the precision filter plate. A base plate is movably connected to the bottom of the precision filter plate. The bottom of the precision filter plate is fixedly connected to the rotating shaft in the drive mechanism.

[0013] Furthermore, the drive mechanism includes a rotating bracket, a rotating shaft is fixedly connected to the middle of the rotating bracket, a base is fixedly installed at the bottom of the rotating shaft, a support seat is movably sleeved on the outside of the rotating shaft, and the rotating shaft extends to the bottom of the support seat.

[0014] Furthermore, a groove is provided on one side of the support base, a turntable is installed inside the groove, a transmission belt is sleeved on the outside of the turntable and the rotating shaft, and a motor is fixedly installed on the top of the groove.

[0015] Furthermore, the turntable extends to the top of the groove, and the turntable is electrically connected to an external motor.

[0016] This utility model has the following beneficial effects:

[0017] (1) This utility model: It sets up a vertical series design of coarse filter structure and fine filter structure, and quickly disassembles and assembles the connecting parts to realize the optimization of the graded filtration process. The filter plate filters out the blocks and impurities in the silicone glue, avoids the bottom blockage, and thus reduces the frequency of cleaning work and improves the filtration work.

[0018] (2) This utility model: The precision filter plate is linked with the drive mechanism. The filter plate is dynamically filtered by rotating the shaft and discharged through the discharge pipe. This accelerates the flow of silicone rubber inside the second filter chamber. This method enables the filtration work to be completed quickly, thereby improving the efficiency of the filtration work.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 As shown, this utility model is a filtration device for silicone sealant production, including a coarse filter structure 1. The coarse filter structure 1 includes a storage tank 101, a first filter chamber 102 at the bottom of the storage tank 101, a filter plate 103 installed inside the first filter chamber 102, connecting parts on both sides of the top of the first filter chamber 102, and a fine filter structure 2 connected to the bottom of the first filter chamber 102. The fine filter structure 2 includes a second filter chamber 201, a precision filter plate 202 and a discharge pipe 204 installed inside the second filter chamber 201, a base plate 203 at the bottom of the precision filter plate 202, and a drive mechanism 3 connected to the bottom of the precision filter plate 202. The drive mechanism 3 includes a rotating bracket 301, a rotating shaft 302 installed at the center of the rotating bracket 301, a support seat 303 sleeved on the outside of the rotating shaft 302, and a base 305 connected to the bottom of the rotating shaft 302.

[0031] The design of the coarse filter structure 1 and the fine filter structure 2 in a vertical series allows for quick assembly and disassembly via connectors, optimizing the process flow of graded filtration. The filter plate 103 filters out lumps and impurities in the silicone sealant. The coarse filter structure 1 intercepts large particles of impurities first, reducing the load on the fine filter structure 2, preventing the precision filter plate 202 from clogging too quickly, and extending its service life. The modular design allows the coarse filter structure 1 to be disassembled and cleaned separately without the need for frequent disassembly of the entire filtration system, improving maintenance efficiency.

[0032] The bottom of the storage hopper 101 is movably connected to the top of the first filter chamber 102. A filter plate 103 is movably installed on the top of the first filter chamber 102. Filter openings are evenly distributed on the outside of the filter plate 103. Mounting holes are opened on both sides of the top of the first filter chamber 102. Connectors are movably installed inside the mounting holes. The connectors include a connecting post 104, a protrusion 105, and a hook 106. The silicone sealant is initially filtered through the filter plate 103, so that lumps and larger impurities are retained on the top of the filter plate 103, preventing them from entering the inner bottom layer and causing accumulation and blockage.

[0033] The connecting post 104 is externally connected to the inside of the mounting hole. A protrusion 105 is fixedly installed at the bottom of the connecting post 104, and a hook 106 is movably sleeved on the top of the connecting post 104. The protrusion 105 is movably engaged with the second filter chamber 201 in the fine filter structure 2. Through the cooperation of the connecting post 104 and the protrusion 105, the connection effect of the first filter chamber 102 and the second filter chamber 201 is enhanced.

[0034] The precision filter plate 202 is linked with the drive mechanism 3. The rotation of the rotating shaft 302 drives the filter plate to filter dynamically, and the discharge pipe 204 discharges the material, which accelerates the flow of silicone resin inside the second filter chamber 201. This method enables the filtration work to be completed quickly, thereby improving the efficiency of the filtration work.

[0035] The second filter chamber 201 has grooves on both sides of the top center, which are adapted to the protrusions 105. The second filter chamber 201 has sealing rings movably fitted on both sides of the outside. A precision filter plate 202 is movably installed in the middle of the second filter chamber 201. The precision filter plate 202 has several precision openings on its outside. A discharge pipe 204 is fixedly installed at the bottom of the precision filter plate 202. A base plate 203 is movably connected to the bottom of the precision filter plate 202. The bottom of the precision filter plate 202 is fixedly connected to the rotating shaft 302 in the drive mechanism 3. The drive mechanism 3 drives the transmission belt 304 to rotate, so that the precision filter plate 202 rotates to perform filtration.

[0036] The drive mechanism 3 includes a rotating bracket 301, a rotating shaft 302 fixedly connected to the middle of the rotating bracket 301, a base 305 fixedly installed at the bottom of the rotating shaft 302, and a support seat 303 movably sleeved on the outside of the rotating shaft 302. The rotating shaft 302 extends to the bottom of the support seat 303. Through the cooperation of the rotating shaft 302 and the transmission belt 304, the precision filter plate 202 is rotated synchronously for filtration, thereby improving the efficiency of filtration and accelerating the entry of silicone sealant into the discharge pipe 204.

[0037] The support base 303 has a groove on one side, and a turntable is installed inside the groove. A transmission belt 304 is fitted around the turntable and the outside of the rotating shaft 302. A motor 306 is fixedly installed on the top of the groove. The support base 303 ensures the stable operation of the rotating shaft 302 and reduces the impact of vibration on the filtration accuracy.

[0038] The turntable extends to the top of the groove and is electrically connected to the external motor 306.

[0039] Working principle: During use, silicone resin raw materials are transported from the production equipment to the storage tank 101 of the filtration device. Since silicone resin usually has a high viscosity, the wide-mouth design of the storage tank 101 facilitates the smooth entry of materials. The silicone resin flows into the first filtration chamber 102 under the action of gravity and undergoes preliminary filtration through the filter plate 103. The filter plate 103 has a large pore size and is mainly used to filter incompletely dispersed filler clumps and impurities. The silicone resin enters the second filtration chamber 201 and undergoes fine filtration through the precision filter plate 202. The precision filter plate 202 has a small pore size and can remove impurities such as tiny particles and gel clumps. Through multi-layer filtration, clogging of components is avoided. The drive mechanism 3 is started, and the motor 306 drives the rotating shaft 302 to rotate through the transmission belt 304, so that the precision filter plate 202 rotates synchronously. The filtered high-purity silicone resin flows out through the discharge pipe 204 and drives the precision filter plate 202 to rotate through the rotating bracket 301, thereby improving the filtration speed.
