Description

Technical Field

[0001] This application relates to the field of filtration devices, and more specifically, to a filtration device for producing flame-retardant emulsions. Background Technology

[0002] In the production process of flame retardant emulsions, filtration devices are required for filtration. For some flame retardant emulsions with high viscosity, pressure filter devices are used for filtration. However, after a period of use, impurities will clog the inside of the filter element, which often needs to be replaced or the disassembled filter element needs to be cleaned and recycled. Therefore, disassembly and reinstallation take a certain amount of time and reduce filtration efficiency. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a flame-retardant emulsion production filtration device, which aims to improve the problem that disassembly and reinstallation require a certain amount of time and reduce filtration efficiency.

[0004] This application provides a flame-retardant emulsion production filtration device, including a frame and a filtration assembly. The filtration assembly includes a filter press, a filter element holder, a filter element, a feed guide screw, and a blocking plate. A first sliding sealing plate is provided at the bottom of the filter press, and a second sliding sealing plate is symmetrically arranged on the filter element holder. The filter element holder is fixedly connected to the bottom inner side of the filter press, and the filter elements are symmetrically arranged on both sides of the filter element holder. The feed guide screw is symmetrically arranged on both sides of the filter element holder, and the blocking plate is symmetrically arranged on both sides of the filter press. The filter element holder and the second sliding sealing plate divide the filter press into a liquid storage area and a filtration area, and the filter element is located inside the filtration area.

[0005] In one specific implementation, the filter press includes a box body, a pressure plate, and a first telescopic member. The pressure plate is slidably connected to the box body, the first telescopic member is fixedly connected to the upper part of the box body, and the output end of the first telescopic member is fixedly connected to the pressure plate.

[0006] In one specific implementation, the upper part of the pressure plate is provided with a liquid inlet pipe, and the liquid inlet pipe is provided with a solenoid valve.

[0007] In one specific implementation, the box body has a discharge port at the bottom, and the first sliding sealing plate blocks the discharge port.

[0008] In one specific implementation, the filter element holder is provided with filter screens on both sides of the filter element.

[0009] In one specific implementation, a second telescopic member is provided on one side of both the first sliding sealing plate and the second sliding sealing plate.

[0010] In one specific implementation, the guide screw includes a motor and a screw rod, the screw rod is rotatably connected to the inside of the housing, the motor is fixedly connected to the housing, and the output end of the motor is fixedly connected to one end of the screw rod.

[0011] In one specific implementation, the blocking plate includes a sealing cover, a first frame, a second frame, and a third telescopic member. One side of the sealing cover is fixedly connected to one side of the first frame, the other side of the first frame is slidably connected to one side of the second frame, the other side of the second frame is fixedly connected to the box body, the end of the third telescopic member is fixedly connected to the second frame, and the output end of the third telescopic member is fixedly connected to the sealing cover.

[0012] Beneficial Effects: This application provides a flame-retardant emulsion production filtration device. The produced flame-retardant emulsion is transported into a filter press chamber. Pressure is applied to the emulsion inside the chamber, opening the second sliding sealing plate on one side of the filter element holder. The emulsion then flows through the open second sliding sealing plate to the filter element holder. Continuous pressure filters the emulsion through the filter element on one side of the filter element holder. After the filter element has been used for a certain period, or when its permeability decreases, the second sliding sealing plate on that side is closed, and the second sliding sealing plate on the other side of the filter element holder is opened. Then, the first sliding sealing plate is closed. At this point, the bottom of the filter press chamber is closed. The sealing end of the plugging plate on the side of the used filter element moves, opening one side of the filter press chamber. The filter press continuously applies pressure to the flame-retardant emulsion. At this time, the flame-retardant emulsion will be filtered through the filter element on the side where the second sliding sealing plate is just opened. Since the first sliding sealing plate is closed at this time, the flame-retardant emulsion will flow towards the filter element that has just been used, thus backflushing the filter element. At the same time, the guide screw will remove the impurities accumulated on one side of this filter element. The removed impurities and flame-retardant emulsion undergo secondary treatment to completely separate the flame-retardant emulsion. After the impurities remaining on this filter element are removed by backflushing, the first sliding sealing plate is opened to carry out normal filtration operations. During the entire process, the flame-retardant emulsion is used to backflush the filter element and facilitate the removal of impurities. Alternatively, the filter element can be backflushed directly with cleaning fluid, which makes it more convenient and faster to clean the filter element and greatly improves the filtration efficiency.

The filter element frame 220 is fixedly connected to the bottom inner side of the filter press 210. Filter elements 230 are symmetrically arranged on both sides of the filter element frame 220. The feed guide screw 240 is symmetrically arranged on both sides of the filter element frame 220. The blocking plate 250 is symmetrically arranged on both sides of the filter press 210. On the side, the filter element holder 220 and the second sliding sealing plate 228 divide the filter press 210 into a liquid storage area and a filtration area. The filter element 230 is located inside the filtration area. The filter press 210 includes a housing 211, a pressure plate 212, and a first telescopic member 213. The pressure plate 212 is slidably connected to the housing 211, and the first telescopic member 213 is fixedly connected to the upper part of the housing 211. The output end of the first telescopic member 213 is fixedly connected to the pressure plate 212. An inlet pipe 214 is provided on the upper part of the pressure plate 212, and the inlet pipe 214 is equipped with a solenoid valve. The housing 211 has a discharge port 215 at the bottom, and a first sliding sealing plate 218 blocks the discharge port 215. A filter element frame 220 has filter screens 222 on both sides of the filter element 230. A second telescopic member 219 is provided on one side of both the first and second sliding sealing plates 218. The guide screw 240 includes a motor 241 and a screw rod 242. The screw rod 242 is rotatably connected to the inside of the housing 211, and the motor 241 is fixedly connected to the housing 211. The output end of the motor 241 is connected to the screw rod. One end of the rod 242 is fixedly connected. The blocking plate 250 includes a sealing cover 251, a first frame 252, a second frame 253, and a third telescopic member 254. One side of the sealing cover 251 is fixedly connected to one side of the first frame 252, the other side of the first frame 252 is slidably connected to one side of the second frame 253, the other side of the second frame 253 is fixedly connected to the box 211, the end of the third telescopic member 254 is fixedly connected to the second frame 253, and the output end of the third telescopic member 254 is fixedly connected to the sealing cover 251.

[0023] The working principle of this flame-retardant emulsion production filtration device is as follows: The produced flame-retardant emulsion is transported into the filter press 210. Pressure is applied to the flame-retardant emulsion inside the filter press 210, opening the second sliding sealing plate 228 on one side of the filter element holder 220. The flame-retardant emulsion then flows through the open second sliding sealing plate 228 to the filter element holder 220. Continuous pressure filters the flame-retardant emulsion through the filter element 230 on one side of the filter element holder 220. After the filter element 230 has been used for a certain period, or when its permeability decreases, the second sliding sealing plate 228 on this side is closed, and the second sliding sealing plate 228 on the other side of the filter element holder 220 is opened. Then, the first sliding sealing plate 218 is closed. At this time, the bottom of the filter press 210 is closed. The sealing end of the plugging plate 250 on the side of the used filter element 230 moves, opening one side of the filter press 210. Pressure is continuously applied to the flame-retardant emulsion, which then passes through the filter element 230 on the side where the second sliding sealing plate 228 has just been opened. Since the first sliding sealing plate 218 is closed at this time, the flame-retardant emulsion flows towards the used filter element 230, backflushing the filter element 230. At the same time, the feed screw 240 is activated to remove the impurities accumulated on one side of the filter element 230. The removed impurities and the flame-retardant emulsion undergo secondary treatment to completely separate the flame-retardant emulsion. After the impurities remaining on the filter element 230 are removed by backflushing, the first sliding sealing plate 218 is opened to carry out normal filtration. Throughout the entire process, the flame-retardant emulsion is used to backflush the filter element 230, which facilitates the removal of impurities. Alternatively, the filter element 230 can be backflushed directly with cleaning fluid, making it easier and faster to clean the filter element 230 and greatly improving the filtration efficiency.

[0024] It should be noted that the first telescopic component 213, the second telescopic component 219, and the third telescopic component 254 are all electric push rods.
