Description

Technical Field

[0001] This invention relates to the field of antibacterial liquid dressing processing, and more particularly to a raw material filtration device for processing antibacterial liquid dressings. Background Technology

[0002] Liquid dressings are disinfectant liquids that act directly on pathogens, inhibiting most bacteria, viruses, and protozoa, including Staphylococcus aureus, Escherichia coli, and hemolytic streptococci. When sprayed onto a wound, this liquid forms a protective film, protecting the wound and isolating it from external pathogens, while also killing bacteria around the wound. Used on abdominal and perineal wounds, it promotes wound healing and prevents infection. However, liquid dressings are often made from plant extracts, which contain plant residues that can affect their effectiveness if used directly; therefore, filtration is necessary.

[0003] In existing technologies, liquid is typically initially filtered through a filter screen and then further filtered using a filter cloth. However, the liquid discharge location is fixed, resulting in incomplete filtration by the filter screen, which is prone to clogging and cannot be cleaned. Filtering with a filter cloth is also slow because the filter cloth is fixed in place and cannot be shaken to speed up the filtration process. Therefore, we propose a raw material filtration device for processing antibacterial liquid dressings. Summary of the Invention

[0004] Purpose of the Invention: The purpose of this invention is to provide a raw material filtration device for processing antibacterial liquid dressings, which solves the problems in the prior art where the liquid discharge position is fixed during the filtration of liquid dressing raw materials, resulting in a limited filtration range and incomplete filtration, and the inability to automatically clean the filter screen surface, easily causing filter screen blockage, seriously affecting the continuity and filtration effect of raw material filtration. Another purpose of this invention is to provide a raw material filtration device for processing antibacterial liquid dressings that solves the problems of traditional fixed filter cloth filtration structures, which cannot accelerate raw material screening through shaking, resulting in slow filtration rate, low working efficiency, and difficulty in adapting to the needs of batch antibacterial liquid dressing raw material processing and production, effectively improving the overall filtration efficiency and ensuring the filtration quality and production progress of liquid dressing raw materials.

[0005] Technical solution: A raw material filtration device for processing antibacterial liquid dressings, comprising a filter cylinder, wherein the filter cylinder is a hollow structure with an open top, and a cylinder cover is installed on the top of the filter cylinder by bolts. A liquid inlet pipe is fixedly connected to the left side of the upper surface of the cylinder cover. A motor is fixed at the center of the upper surface of the cylinder cover. The bottom end of the output shaft of the motor penetrates into the interior of the filter cylinder and is fixed with a central rotating plate. The central rotating plate is a hollow disc with an open upper surface, and its upper surface is in contact with the lower surface of the cylinder cover. A drain pipe is integrally formed on the left side of the lower surface of the central rotating plate.

[0006] A rotating rod is fixed to the lower surface of the turntable. A filter screen is rotatably installed at the bottom end of the rotating rod via a rotating shaft. Multiple elastic telescopic rods are fixed to the bottom edge of the filter screen. The bottom ends of the multiple elastic telescopic rods are fixed to a circular frame. A filter cloth is fixedly installed at the bottom of the circular frame.

[0007] Furthermore, a drain valve is fixedly installed at the bottom of the filter cartridge.

[0008] Furthermore, the lower surface edge of the filter cartridge is fixed with multiple support legs, and the bottom end of each support leg is fixedly equipped with a caster wheel.

[0009] Furthermore, a mounting plate is fixed to the left side of the filter cartridge, and a second motor is fixed to the upper surface of the mounting plate. The right end of the output shaft of the second motor is fixed to a dial plate located inside the filter cartridge, and multiple dialing ports are opened on the outer side of the dial plate.

[0010] Furthermore, a push block is fixed to the left side of the lower surface of the circular frame, and the push block engages with the inside of the actuation port at the top of the actuation disk.

[0011] Furthermore, the filter screen has multiple positioning holes on its outer side, and multiple L-shaped guide plates are fixed on the outer wall of the filter cylinder. A positioning post is slidably installed on the inner side of the L-shaped guide plate. A spring is fixed between the positioning post and the L-shaped guide plate. One end of the positioning post near the center of the filter cylinder passes through the interior of the filter cylinder and is inserted into the inner side of the positioning hole.

[0012] Furthermore, a sleeve is fixed to the outer wall of the rotating rod, and multiple cleaning brushes are fixed to the outer wall of the sleeve, with the lower surface of the cleaning brushes adhering to the upper surface of the filter screen.

[0013] Beneficial effects: The device is equipped with a rotatable transfer and drainage structure. The motor drives the transfer plate to rotate the drainage pipe, which can evenly spray the introduced raw material liquid to various areas of the filter structure below, thus changing the problems of concentrated accumulation of raw materials and local filtration overload caused by the traditional fixed liquid discharge method.

[0014] With the dual-stage filtration structure consisting of a filter screen and a filter cloth, it can intercept impurities such as plant residues in the raw materials step by step, purifying the raw material liquid layer by layer, effectively improving the filtration cleanliness of the antibacterial liquid dressing raw materials, ensuring the quality of raw materials for subsequent dressing processing, and accurately meeting the quality standards of product production.

[0015] The device uses a positioning column and spring mechanism to lock the filter screen in place, keeping it fixed during the filtration process. As the turntable rotates to drain the liquid, the outer cleaning brush continuously rotates and wipes the filter screen surface, cleaning impurities and residues adhering to the filter holes in real time. This prevents filter clogging at its source, eliminating the need for frequent manual shutdowns for cleaning, effectively ensuring continuous filtration operations, reducing equipment downtime for maintenance, and improving overall equipment stability.

[0016] The device is equipped with an independent drive mechanism. During operation, the motor drives the dial to rotate continuously. The dial intermittently pushes the circular frame above the filter cloth with the push port. At the same time, the elastic extension and retraction characteristics of the elastic telescopic rod cause the filter cloth to shake up and down continuously. This dynamic filtration method can quickly screen the raw material liquid on the surface of the filter cloth, avoid the accumulation of raw material residue covering the surface of the filter cloth, greatly accelerate the liquid penetration speed, improve the efficiency of secondary filtration, and is suitable for batch and large-scale antibacterial liquid dressing raw material processing and production scenarios.

[0017] The device's cylinder cover features a bolt-on detachable installation structure, allowing for quick access to the internal space of the filter cylinder. This facilitates regular inspection, maintenance, and deep cleaning of internal components such as the filter screen, filter cloth, and cleaning structure, reducing equipment maintenance difficulty and costs. Additionally, the device is equipped with support legs and casters at the bottom. The support legs ensure overall stability during operation, while the casters allow for flexible movement of the entire unit, enabling rapid adaptation to the operational needs of different processing stations. This significantly enhances the device's adaptability and ease of use. Attached Figure Description

[0024] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example

[0026] like Figures 1-5 As shown, a raw material filtration device for processing antibacterial liquid dressings is provided, including a filter cylinder 1. The filter cylinder 1 has a hollow internal structure with an open top. A cylinder cover 2 is installed on the top of the filter cylinder 1 by bolts. An inlet pipe 3 is fixedly connected to the left side of the upper surface of the cylinder cover 2. A motor 4 is fixed at the center of the upper surface of the cylinder cover 2. The bottom end of the output shaft of the motor 4 passes through the interior of the filter cylinder 1 and is fixed with a central rotating plate 5. The central rotating plate 5 is a hollow internal disc with an open upper surface, and its upper surface is in contact with the lower surface of the cylinder cover 2. A drain pipe 6 is integrally formed on the left side of the lower surface of the central rotating plate 5.

[0027] A drain valve 12 is fixedly installed at the bottom of the filter cartridge 1;

[0028] Multiple support legs 13 are fixed to the lower surface edge of the filter cartridge 1, and universal wheels 14 are fixedly installed at the bottom of the support legs 13.

[0029] Workers can move the entire device to the designated processing position using the casters 14, and use the support legs 13 to provide stable support for the filter cylinder 1, ensuring the stability of the overall structure during operation. The internal structure of the filter cylinder 1 can be inspected, maintained, and cleaned by removing the cover 2. During processing, the antibacterial liquid dressing raw material is introduced into the turntable 5 through the liquid inlet pipe 3 at the top of the cover 2, and discharged into the filter cylinder 1 through the liquid outlet pipe 6 at the bottom of the turntable 5. The raw material falls into the lower filtration structure to complete the graded filtration operation. The clean liquid after filtration can be discharged through the liquid outlet valve 12 at the bottom of the filter cylinder 1, completing the raw material filtration and discharge operation.

[0030] After the liquid enters, the starting motor 4 can drive the central rotating plate 5 to rotate, causing the drain pipe 6 to rotate as well, thereby discharging the liquid to different positions in the lower filter structure, making the filtration more comprehensive and avoiding local filtration problems.

[0031] A rotating rod 7 is fixed on the lower surface of the turntable 5. A filter screen 8 is installed at the bottom of the rotating rod 7 via a rotating shaft. Multiple elastic telescopic rods 9 are fixed at the bottom edge of the filter screen 8. A circular frame 10 is fixed at the bottom of the multiple elastic telescopic rods 9. A filter cloth 11 is fixed at the bottom of the circular frame 10.

[0032] Multiple positioning holes 19 are provided on the outer side of the filter screen 8. Multiple L-shaped guide plates 20 are fixed on the outer side wall of the filter cylinder 1. A positioning post 21 is slidably installed on the inner side of the L-shaped guide plate 20. A spring 22 is fixed between the positioning post 21 and the L-shaped guide plate 20. The end of the positioning post 21 near the center of the filter cylinder 1 passes through the interior of the filter cylinder 1 and is inserted into the inner side of the positioning hole 19.

[0033] A sleeve 24 is fixed to the outer wall of the rotating rod 7, and multiple cleaning brushes 23 are fixed to the outer wall of the sleeve 24. The lower surface of the cleaning brushes 23 is in contact with the upper surface of the filter screen 8.

[0034] The positioning post 21 on the inner side of the L-shaped guide plate 20 on the outer side of the filter cylinder 1 is inserted into the positioning hole 19 on the outer side of the filter screen 8 under the elastic force of the spring 22, which can temporarily position and fix the filter screen 8.

[0035] This allows the motor 4 to drive and control the rotation of the central turntable 5 during the liquid drainage process, while the filter screen 8 remains stationary. As the central turntable 5 rotates, the sleeve 24 and cleaning brush 23 on the outside of the rotating rod 7 will rotate and clean the surface of the filter screen 8, thus preventing the filter screen 8 from becoming clogged.

[0036] A mounting plate 15 is fixed on the left side of the filter cartridge 1. A motor 25 is fixed on the upper surface of the mounting plate 15. A toggle plate 16 is fixed on the right end of the output shaft of the motor 25 inside the filter cartridge 1. Multiple toggle ports 17 are opened on the outer side of the toggle plate 16.

[0037] A push block 18 is fixed to the left side of the lower surface of the circular frame 10. The push block 18 is engaged inside the actuation port 17 at the top of the actuation disk 16.

[0038] While the filter screen 8 performs initial filtration, the motor 25 on the mounting plate 15 is started. The motor 25 drives the agitator 16 to rotate continuously. During the rotation of the agitator 16, the outer agitator port 17 intermittently engages and pushes the push block 18 at the bottom of the circular frame 10. With the elastic extension and retraction of the elastic telescopic rod 9, the circular frame 10 and the filter cloth 11 at the bottom continuously shake up and down, effectively accelerating the screening speed of the raw materials on the surface of the filter cloth 11, avoiding the accumulation of raw material residue on the surface of the filter cloth 11, and greatly improving the efficiency of secondary filtration. At the same time, through the cooperation of the dual filtration structure, plant residues in the liquid dressing raw materials are effectively removed, ensuring the filtration quality of the raw materials and meeting the needs of batch processing and production.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
