Description

Technical Field

[0001] This utility model relates to the field of antibacterial gel production technology, and in particular to a raw material filtration device for antibacterial gel production. Background Technology

[0002] ① Traditional antibacterial gel filtration devices fix the filter element with flange bolts, and the filter element and the housing rely on multiple layers of sealing gaskets to achieve a static seal. Under the impact of high-pressure fluid, this type of structure is prone to axial displacement of the filter element, which can cause the sealing interface to loosen and lead to leakage risks. After the filter element becomes clogged, the flange assembly must be completely disassembled for manual cleaning. High-viscosity gel residues adhere to the surface of the filter element and are difficult to remove completely. Frequent disassembly and assembly not only aggravates the wear of sealing elements, but also damages the sterile environment by exposing the internal parts of the equipment during operation, which seriously affects continuous production efficiency.

[0003] ② To address the issues of sealing and disassembly efficiency, some solutions use a spin-locking structure to replace traditional flange bolts. By rotating the gland to compress the elastic sealing ring, radial deformation is generated, enabling quick installation and disassembly of the filter element. This design simplifies the operation process through threaded spin-locking, reduces manual disassembly time, and maintains the sealing effect by relying on the deformation compensation of the elastic sealing ring when the fluid pressure fluctuates.

[0004] ③ Although the spinning structure shortens the filter element disassembly and assembly time, the clogging problem caused by the accumulation of impurities on the filter element surface is not fundamentally solved; the frequent shutdown cleaning operation mode limits the effective operating cycle of the equipment, and manual intervention can easily cause filter element damage or secondary pollution; more importantly, after long-term and repeated use, the threads of the spinning assembly wear down, resulting in a decrease in sealing pressure, and the elastic sealing ring still needs to be replaced as a whole after fatigue failure; these problems reveal that the existing technology only focuses on local optimization of sealing and disassembly, but lacks online cleaning capabilities that are coordinated with the filtration process, and cannot meet the core requirements of antibacterial gel production for efficient and airtight cleaning. Utility Model Content

[0005] The purpose of this utility model is to provide a raw material filtration device for the production of antibacterial gel. It addresses the problems of thread wear, sealing failure, and reliance on manual intervention for filter element cleaning caused by frequent disassembly and assembly of existing spun sealing structures. The device achieves a breakthrough in technical contradictions through structural collaborative design.

[0006] To achieve the above objectives, this utility model provides a cylinder cover, a pressure gauge is installed through one side of the top of the cylinder cover, a pressure sensor is provided at the extended end of the pressure gauge, a bracket is installed on the top of the cylinder cover near the pressure gauge by bolts, a rotating motor is fixedly installed inside the bracket, a rotating shaft is provided at the output end of the rotating motor, the rotating shaft passes through the cylinder cover through a sealed bearing and is rotatably installed inside the filter cylinder, a scraper is fixedly installed on the outside of the rotating shaft, and a rubber plate is fixedly installed on the outside of the scraper and fits against the inner wall of the filter element.

[0007] A support mesh is fixedly installed on the outside of the filter element, and a pressure plate is fixedly installed on the top of the filter element. Sealing gaskets are respectively attached to the upper and lower ends of the pressure plate.

[0008] The filter element extends through the filter cylinder, causing the pressure plate to be embedded in the clamping cylinder. The clamping cylinder is fixedly installed at the top of the filter cylinder, and a cylinder cover is installed at the top of the clamping cylinder by bolts.

[0009] The cylinder contains a threaded block installed by threads. The top of the threaded block has a force-bearing hole. The threaded block is tightened by threads and pressed down, causing the sealing gasket to undergo elastic deformation, so that the pressure plate is located inside the cylinder and keeps it sealed.

[0010] The first connector is fixedly installed on the side of the cartridge away from the cover. A conveying pipe is installed on the first connector by bolts, and the other end of the conveying pipe is installed on the second connector by bolts.

[0011] The second connector is fixedly installed at the pumping end of the pump compartment, and the third connector is fixedly installed at the suction end of the pump compartment. The input shaft of the pump compartment is connected to the output shaft of the drive motor through a coupling.

[0012] The filter cylinder is fixedly installed with a discharge connector at the bottom end, a fixing ring is fixedly installed on the radial outer side of the filter cylinder, a support foot is fixedly installed at the bottom end of the fixing ring, and a fixing hole is opened on the support foot.

[0013] This utility model discloses a raw material filtration device for antibacterial gel production, comprising a cap assembly and a filter cartridge working together. A pressure monitoring unit is integrated at the top of the cap, specifically a pressure gauge vertically mounted through one side of the cap, with a pressure sensor built into its extension end to collect real-time pressure data inside the filter cartridge. A bracket is bolted to the other side of the cap, rigidly housing a rotating motor, whose output shaft is vertically connected to the rotating shaft via a coupling. This rotating shaft innovatively employs a through-type sealed bearing structure, achieving dynamic sealing between the shaft and the cap while ensuring the rotating shaft can extend into the internal space of the filter cartridge. At least two sets of scrapers are radially mounted at the end of the rotating shaft, with flexible rubber plates on the outer edges of the scrapers. These rubber plates form a circumferential contact surface with the inner wall of the filter element inside the cartridge through an interference fit.

[0014] When the device is in operation, the rotating motor drives the rotating shaft to rotate, causing the flexible rubber plate to continuously scrape the inner surface of the filter element, effectively removing gel residues adhering to the inside of the filter pores. The pressure sensor provides real-time feedback on pressure fluctuations inside the cylinder via a pressure gauge, triggering a maintenance prompt when the filter element becomes clogged and causes abnormal pressure. This structure, through the linkage between the rotating scraping mechanism and the pressure monitoring system, achieves an online self-cleaning function for the filter element, ensuring that the high-viscosity raw liquid maintains a stable osmotic pressure difference during continuous filtration. The modular design of the cylinder cover and filter cylinder, combined with the through-type sealed bearing, simplifies the maintenance process while ensuring the equipment's airtightness, making it particularly suitable for antimicrobial gel production processes with stringent microbial control requirements.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-4 .

[0023] This utility model provides a raw material filtration device for antibacterial gel production. A filter element 110 is vertically inserted into the cavity of a filter cylinder 122. The support mesh 111 on the outer side of the filter element 110 maintains a clearance fit with the inner wall of the filter cylinder 122. A pressure plate 112 is embedded in the guide groove at the bottom of a retainer 114. A threaded block 115 is screwed into the retainer 114 through its threads. A tool is inserted into the force hole 116 at the top of the threaded block 115 and rotated to move it downwards. The pressure plate 112 is pressed between the threaded block 115 and the stepped surface of the retainer 114, causing the upper and lower sealing gaskets 113 to deform and respectively adhere to the inner wall of the retainer 114 and the surface of the pressure plate 112. The cylinder cover 101 is fixed to the flange face of the retainer 114 by bolts. Pressure gauge 102 penetrates the top of cylinder cover 101 and monitors the internal pressure through pressure sensor 103. Support bracket 104 is bolted to the side of cylinder cover 101 adjacent to pressure gauge 102. Rotary motor 105 is bolted to the inside of support bracket 104, and its output shaft extends through the sealed bearing of cylinder cover 101 into filter cylinder 122. Scraper 108 is fixed to the outside of rotating shaft 106, and rubber plate 109 is bonded to the outer edge of scraper 108 and contacts the inner wall of filter element 110. Pump chamber 120 is bolted to the side of filter cylinder 122. First connector 117 is welded to the side wall of clamp 114 and bolted to one end of delivery pipe 118. The other end of delivery pipe 118 is bolted to... On the second connector 119, the second connector 119 is welded to the pumping end of the pump chamber 120; the third connector 121 is bolted to the suction end of the pump chamber 120, and the drive motor 123 is bolted to the outside of the pump chamber 120 and connected to the input shaft of the pump chamber 120 via a coupling; the discharge connector 124 at the bottom of the filter cartridge 122 is connected to an external collection device via a flange, the fixing ring 125 is welded to the radial outside of the filter cartridge 122, the support leg 126 is bolted to the bottom of the fixing ring 125, and the fixing hole 127 of the support leg 126 is anchored to the operating table surface via anchor bolts; when the equipment is started, the drive motor 123 drives the pump chamber 120 to draw the raw liquid from the third connector 121, and then... The liquid is injected into the cavity between the filter cylinder 122 and the filter element 110 through the delivery pipe 118 and the first connector 117. After the liquid passes through the filter element 110 and completes filtration, it is discharged through the discharge connector 124. When the pressure gauge 102 detects that the pressure inside the cylinder exceeds the set value, the rotating motor 105 drives the scraper 108 to rotate and remove impurities inside the filter element 110. The continuous contact between the rubber plate 109 and the inner wall of the filter element 110 ensures the scraping effect. During maintenance, the pressure of the pressure plate 112 is released by rotating the force hole 116 at the top of the threaded block 115 in the opposite direction with a tool. After removing the bolts of the cylinder cover 101, the filter element 110 can be taken out for cleaning or replacement. The rigid connection between the support leg 126 and the fixing ring 125 prevents displacement during equipment operation.

[0024] Working principle: Driven by the pump chamber 120, the raw liquid enters the filter cartridge 122 through the delivery pipe 118. During the pumping process, the drive motor 123 drives the impeller of the pump chamber 120 to rotate, generating suction force, so that the raw liquid is stably input into the system through the third connector 121. When the filter cartridge 122 is full of raw liquid, the support mesh 111 on the inner side of the filter element 110 provides rigid support for the multi-layer filter media, preventing the filter element 110 from being deformed by pressure. At the same time, the top of the filter element 110 forms a dynamic sealing structure through the cooperation of the pressure plate 112 and the sealing gasket 113. The operator uses a tool to engage the threaded block 11 in the clamping cylinder 114 through the force hole 116. At 5 o'clock, the threaded block 115 moves down along the thread on the inner wall of the retainer 114, applying axial pressure to the sealing gaskets 113 at both ends of the pressure plate 112. This causes the elastic sealing gaskets 113 to undergo radial expansion deformation, tightly fitting the inner wall of the retainer 114 and the surface of the pressure plate 112, forming a double sealing interface. This effectively prevents the high-pressure raw liquid from leaking from the top of the filter element 110. During filtration, the raw liquid permeates from the inside of the filter element 110 to the outside under the pressure of the pump chamber 120. Impurities are trapped in the inner channels of the filter element 110, while the clean filtrate passes through the support mesh 111 and enters the outer cavity of the filter cylinder 122. As filtration continues, the rotating motor... 105 drives the rotating shaft 106 via a sealed bearing to rotate the scraper 108. The flexible rubber plate 109 on the outer side of the scraper 108 adheres tightly to the inner wall of the filter element 110 and moves circumferentially, peeling off the gel-like residue adhering to the inner side of the filter element 110 to prevent filter pore blockage. At this time, the pressure gauge 102 monitors the pressure change inside the filter cartridge 122 in real time through the pressure sensor 103. When the pressure value exceeds the set threshold, it indicates that impurities have accumulated inside the filter element 110 and need to be cleaned. The operator can stop the machine for maintenance in time. The filtered liquid is guided to the next process through the discharge connector 124. The combination design of the fixing ring 125 and the support leg 126 is as follows: The entire filter cartridge 122 provides robust support, ensuring the equipment remains stable under vibration conditions. This device, through a combination of threaded rotary sealing and dynamic scraping cleaning, ensures reliable sealing while enabling online cleaning of the filter element 110, significantly extending the filter element 110 replacement cycle. The direct connection design between the pumping system and the filter structure shortens the fluid path and reduces the area of ​​raw liquid retention, making it particularly suitable for the stringent microbial contamination control requirements in antibacterial gel production. The coordinated operation of the pressure monitoring system and the self-cleaning mechanism enables the equipment to maintain stable filtration efficiency at a constant flow rate, adapting to the continuous production requirements of high-viscosity raw liquids.
