Description

Technical Field

[0001] The utility model relates to the technical field of polishing liquid recovery, in particular to a polishing liquid recovery device for optical glass processing. Background Art

[0002] Optical glass in a broad sense also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet and infrared optical glass, fiber optical glass, acousto-optic glass, magneto-optical glass and photochromic glass. Optical glass can be used to manufacture lenses, prisms, reflectors and windows in optical instruments. Components made of optical glass are key components in optical instruments. Polishing liquid is a water-soluble polishing agent that does not contain any sulfur, phosphorus or chlorine additives. The polishing liquid has good degreasing, rust-proof, cleaning and gloss-enhancing properties. The optical glass polishing liquid recovery device is a device that recovers the polishing liquid on the surface of glass during polishing.

[0003] A search revealed a fully automatic waste oil centrifugal filter with application number "202223315848.2," comprising a centrifugal tank mechanism, a drive mechanism, an oil inlet and outlet mechanism, and a scraping mechanism. The centrifugal tank mechanism comprises an outer fixed tank and an inner main barrel, with an oil chamber formed between the inner wall of the outer fixed tank and the outer wall of the inner main barrel. The drive mechanism drives the inner main barrel to rotate at a first speed or a second speed within the outer fixed tank. The oil inlet and outlet mechanism comprises an oil inlet assembly, an oil discharge assembly, an adapter assembly, and a first drive member. The adapter assembly has a docking station and a non-docking station. The scraping mechanism comprises a scraper and a second drive member, with the scraper having a scraping station and a waiting station. This utility model is used to process industrial waste oil, separating oil from suspended sludge through centrifugal force. The station switching between the adapter assembly and the scraping mechanism enables the equipment to meet both filtering and scraping requirements, with good working synergy. Furthermore, the scraper is used to scrape the inner main barrel at a low speed, evenly and smoothly, and with excellent cleaning efficiency.

[0004] The existing polishing liquid recovery device uses a centrifugal filter to filter glass fragments and other small particles in the waste liquid. The filtered impurities are scraped off by a scraper. After working for a long time, the scraper blade will wear out, making it impossible for the blade to scrape the wall normally, affecting the normal discharge process. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a polishing liquid recovery device for optical glass processing to solve the technical problem that the scraper blade will wear out and the blade cannot scrape the wall normally.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a polishing liquid recovery device for optical glass processing, comprising a centrifugal filter, wherein a cylinder is fixedly connected to the bottom of the centrifugal filter, a movable end of the cylinder is rotatably connected to a scraper mechanism, the scraper mechanism comprising a scraper body, one end of the scraper body is slidably connected to a sliding frame, and one end of the sliding frame is fixedly connected to a push rod;

[0007] A sliding groove is provided at one end of the scraper body, and a pressure sensor is fixedly connected to one end of the sliding groove.

[0008] By adopting the above technical solution, the fixed connection between the centrifugal filter and the cylinder, and the rotational connection between the movable end of the cylinder and the scraper mechanism, the scraper mechanism can effectively scrape the inner wall of the centrifugal filter. The driving force of the cylinder can ensure that the scraper body fits tightly to the inner wall of the centrifugal filter, thereby effectively removing attached glass fragments and impurities.

[0009] Furthermore, a scraping blade is provided on the sliding frame, and a locking block is rotatably connected to the top of the sliding frame.

[0010] By adopting the above technical solution, the sharpness and wear resistance of the scraping blade ensure the scraping effect, so that the scraping blade can fit closely to the inner wall of the centrifugal filter. Even if there are slight bumps or unevenness on the inner wall, comprehensive and thorough scraping can be achieved through flexible adjustment of the scraping blade.

[0011] Furthermore, a spring is provided between the sliding groove and the push rod.

[0012] By adopting the above technical solution, the spring is cleverly arranged between the sliding groove and the push rod, providing the scraper mechanism with flexible scraping force adjustment. When the scraper body is pressed against the inner wall of the centrifugal filter, the spring will compress or stretch according to the pressure it receives, thereby automatically adjusting the contact force between the scraper body and the inner wall, which helps to adjust the pressure intensity of the pressure sensor.

[0013] Furthermore, there are two of each of the sliding groove, the push rod and the spring.

[0014] By adopting the above technical solution, two sliding grooves, two push rods and two springs are provided, which enhances the stability and balance of the scraper mechanism. The two sliding grooves are located at both ends of the scraper body, and cooperate with the corresponding push rods and springs to form a stable fulcrum structure.

[0015] Furthermore, one end of the scraper body is arranged in an arc-shaped structure, and the scraper body is rotatably connected to the mounting plate through a rotating shaft.

[0016] By adopting the above technical solution, one end of the scraper body has an arc-shaped structure, which simulates the curvature required to enter the inner wall of the centrifugal tank of the centrifugal filter, so that the scraper body can fit the inner wall more closely and perform all-round and dead-angle scraping.

[0017] Furthermore, a bracket is provided below the centrifugal filter, and a material receiving trolley is provided inside the bracket.

[0018] By adopting the above technical solution, the bracket installed under the centrifugal filter provides a stable support for the entire equipment. The bracket can not only bear the weight of the centrifugal filter and the materials inside it, but also effectively disperse and transmit vibrations, ensuring the stability and safety of the equipment during high-speed operation.

[0019] Furthermore, wheels are provided at the bottom of the material receiving vehicle, and there are four wheels, which are arranged in a rectangular structure.

[0020] By adopting the above technical solution, the four wheels set at the bottom of the material receiving trolley significantly enhance the mobility and flexibility of the material receiving trolley. Whether on smooth ground or on slightly uneven ground, the material receiving trolley can achieve stable and smooth movement through the coordinated action of the four wheels.

[0021] Furthermore, the pressure sensor is electrically connected to an external controller, and a warning light is fixedly connected to the top of the centrifugal filter.

[0022] By adopting the above technical solution, the pressure sensor can accurately sense the pressure exerted on the scraper body during the scraping process and transmit this data to the external controller. The external controller can adjust the thrust of the cylinder in real time based on the received data, thereby ensuring that the scraper mechanism scrapes the inner wall of the centrifugal filter with optimal force.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. The utility model provides a scraper mechanism so that the scraping blade can fit closely to the inside of the centrifugal tank. Under the push of the cylinder, the scraper mechanism can overcome the elastic force of the spring and stably press the scraper body onto the pressure sensor, thereby ensuring that sufficient pressure is applied to the inside of the centrifugal tank for scraping. When the scraper blade is worn and the pressure sensor value is small, the external controller can intelligently identify it and send a signal to drive the cylinder to move, thereby pushing the scraper body to rotate upward to provide greater pressure to scrape the wall of the centrifugal tank, thereby extending the service life of the scraper blade and ensuring the stability and reliability of the scraping effect. When lumps that cannot be scraped off appear on the inner wall, the scraper blade will be pushed backward by the lumps and exert a large force on the pressure sensor, thereby avoiding damage to the scraper blade due to excessive torque. The controller can also trigger a warning light in time to issue a warning, so that maintenance personnel can quickly know that there are lumps that cannot be scraped off and perform maintenance in time, thereby improving the maintainability and safety of the equipment.

[0025] 2. The utility model provides a scraping blade so that when the scraping blade needs to be replaced, the operator only needs to simply turn the locking block to easily unlock and slide out the worn scraping blade, which simplifies the scraping blade replacement process and shortens the replacement time, thereby improving the maintenance efficiency and availability of the equipment. When installing a new scraping blade, the operator only needs to slide the new scraping blade into the corresponding position of the scraper body and turn the locking block again to firmly fix the new scraping blade, avoiding the problem of poor scraping effect or equipment damage caused by loose scraping blade.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure. Example

[0033] Polishing liquid recovery device for optical glass processing, such as Figures 1-4 As shown, it includes a centrifugal filter 1, the bottom of the centrifugal filter 1 is fixedly connected to a cylinder 2, the movable end of the cylinder 2 is rotatably connected to a scraper mechanism 3, the scraper mechanism 3 includes a scraper body 301, one end of the scraper body 301 is slidably connected to a sliding frame 302, and one end of the sliding frame 302 is fixedly connected to a push rod 303;

[0034] A sliding groove 304 is provided at one end of the scraper body 301, and a pressure sensor 305 is fixedly connected to one end of the sliding groove 304. When the scraper body 301 is pushed toward the inner wall of the centrifugal filter 1 by overcoming the elastic force of the spring 308 under the push of the cylinder 2, the pressure sensor 305 can detect the pressure on the scraper body 301 in real time, ensuring that the scraping force is moderate, avoiding damage to the inner wall of the centrifugal filter 1 or the scraper body 301 itself due to excessive force, and preventing the problem of inability to completely remove glass fragments due to insufficient force, thereby facilitating the maintenance and replacement of the scraper mechanism 3. When the scraper blade 306 is worn, the worn scraper blade 306 can be easily unlocked and slid out by rotating the locking block 307, and then a new scraper blade 306 can be installed and locked, thereby realizing rapid replacement of the scraper blade 306 and reducing downtime and maintenance costs.

[0035] See Figure 2 、 Figure 3 and Figure 4 A spring 308 is provided between the sliding groove 304 and the push rod 303. The presence of the spring 308 also enhances the buffering capacity and durability of the scraper mechanism 3. During the scraping process, if stubborn lumps or foreign objects that are difficult to remove are encountered, the spring 308 can absorb some of the impact force, reducing the instantaneous pressure on the scraper body 301 and scraping edge 306, thereby extending their service life. The spring 308 also enables the scraper mechanism 3 to quickly return to its initial position after scraping, ready for the next scraping, thereby improving the continuous working capacity and efficiency of the equipment.

[0036] See Figure 2 、 Figure 3 and Figure 4There are two sliding grooves 304, two push rods 303 and two springs 308. The double push rods 303 and double sliding grooves 304 also facilitate the maintenance and replacement of the scraper mechanism 3. When the scraping blade 306 needs to be replaced or other maintenance operations need to be performed, maintenance personnel can more easily disassemble and install the scraper body 301 without worrying about stability problems caused by single-point support.

[0037] See Figure 2 、 Figure 3 and Figure 4 One end of the scraper body 301 is arranged in an arc-shaped structure, and the scraper body 301 is rotatably connected to the mounting plate 7 through the rotating shaft. The scraper body 301 is rotatably connected to the mounting plate 7 through the rotating shaft, providing a stable rotation support point for the scraper body 301.

[0038] See Figure 2 、 Figure 3 and Figure 4 A bracket 4 is provided at the bottom of the centrifugal filter 1, and a material receiving cart 5 is provided inside the bracket 4. The material receiving cart 5 provided inside the bracket 4 provides a convenient collection container for the recovery of the polishing liquid. In the process of filtering and separating the polishing liquid by the centrifugal filter 1, the impurities generated can be directly discharged into the material receiving cart 5, avoiding splashing and pollution of waste materials.

[0039] See Figure 2 、 Figure 3 and Figure 4 The bottom of the receiving trolley 5 is provided with wheels 6, and there are four wheels 6. The four wheels 6 are arranged in a rectangular structure. During the polishing liquid recovery process, when the receiving trolley 5 is full of waste materials, the operator only needs to gently push the receiving trolley 5 to easily move it to the designated waste treatment area, which reduces the labor intensity of the operator and improves the efficiency and environmental protection of waste liquid treatment.

[0040] See Figure 2 、 Figure 3 and Figure 4 The pressure sensor 305 is electrically connected to the external controller. A warning light 8 is fixedly connected to the top of the centrifugal filter 1. When the scraping force of the scraper mechanism 3 is abnormal or the equipment fails, the external controller will immediately send a signal to the warning light 8 to light up or flash to alert the operator. This immediate visual warning can quickly attract the attention of the operator and prompt them to take timely measures to solve the problem, thereby avoiding production interruption or safety accidents caused by equipment failure.

[0041] The working principle of the present invention is as follows: first, the cylinder 2 is started, which pushes the scraper mechanism 3 to move, driving the scraping blade 306 to be mortgaged into the interior of the centrifuge tank, so that the sliding frame 302 can push the scraper body 301 to overcome the elastic force of the spring 308 and press onto the pressure sensor 305. It can be determined based on the value of the pressure sensor 305 that sufficient pressure is applied to the interior of the centrifuge tank, and then the interior of the centrifuge tank can be scraped off, so that the glass residue retained inside can be scraped off;

[0042] When the scraping blade 306 is worn, the value of the pressure sensor 305 becomes smaller. At this time, the external controller sends a signal to drive the cylinder 2 to move, so that the scraper body 301 can be pushed to rotate upward, thereby providing sufficient pressure to scrape the wall of the centrifuge tank.

[0043] When lumps that cannot be scraped off appear on the inner wall, the scraping blade 306 will be pushed backward by the lumps, thereby exerting a large force on the pressure sensor 305 to avoid damage to the scraping blade 306. At the same time, the controller can issue a warning through the warning light 8, so that maintenance personnel can be informed of the presence of lumps that cannot be scraped off and carry out timely repairs. Example

[0044] See Figure 2 、 Figure 3 and Figure 4 A scraping blade 306 is provided on the sliding frame 302, and a locking block 307 is rotatably connected to the top of the sliding frame 302. When the scraping blade 306 is worn or damaged due to long-term use, the maintenance personnel only need to simply rotate the locking block 307 to easily unlock the scraping blade 306, and then slide it out of the sliding frame 302, install a new scraping blade 306, and rotate the locking block 307 again to fix the new scraping blade, which simplifies the replacement process of the scraping blade 306, greatly shortens the downtime, and improves the maintenance efficiency and availability of the equipment.

[0045] The implementation principle of the present invention is as follows: first, when the scraper blade 306 needs to be replaced, the locking block 307 is rotated, and then the worn scraper blade 306 is slid out, and then a new scraper blade 306 is installed, and the locking block 307 is rotated to fix the scraper blade 306, thereby achieving a quick replacement operation.

[0046] Parts not involved in the present invention are the same as those in the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0047] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
