[0002] Demulsifier filter is a device used to process demulsifiers. Its main function is to remove impurities and particulate matter in demulsifiers to improve the purity and quality of demulsifiers. This device usually uses filter media, such as filter screens, filter papers, filter elements, etc., to intercept impurities in demulsifiers. The design and selection of the filter device will be considered based on factors such as the properties of the demulsifier, flow rate, impurity content, etc. to ensure that impurities can be effectively removed while maintaining high filtration efficiency and flux.

[0003] When filtering the demulsifier, the impurities contained therein may cause the filter screen to be blocked during filtration, so the filter screen needs to be replaced frequently, which is very inconvenient. In addition, if the demulsifier is stored for a long time, it may clump and the like. The filter screen in the existing filtering device cannot effectively break it up before filtering, and the filtering effect is not efficient enough. Utility Model Content

When the screw sleeve slides back and forth, the main brush rod will be driven by the connecting block to clean the filter screen, so as to prevent the impurities contained in the demulsifier from accumulating on the filter screen during filtering, causing the filter screen to be blocked and lose the filtering effect.

[0013] Preferably, the left side of the linkage block is fixedly connected to a secondary brush rod, and the guide block drives the linkage block to swing up and down, causing the slider to slide relatively in the slide groove, so that the spring is repeatedly compressed and then bounces up to reset the slider, and the bottom surface of the secondary brush rod is fixedly connected to a scraper strip.

[0014] Compared with the prior art, the utility model provides a demulsifier filtering device, which has the following beneficial effects:

[0015] 1.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a demulsifier filtering device, including a body 1, a bracket 3 is fixedly connected to the bottom surface of the body 1, a feed hopper 4 is penetrated and fixedly connected to the top surface of the body 1, and a discharge hopper 5 is penetrated and fixedly connected to the bottom surface of the body 1. A control unit 2 is arranged inside the body 1, and the control unit 2 includes: a motor 21, a reciprocating screw 22, a transmission wheel 23, a transmission belt 24, a baffle 25, a filter screen 26, a screw sleeve 27, a connecting block 28, a main brush rod 29, a brush 210, a linkage block 211, a slide groove 212, a slider 213, a spring 214, a connecting strip 215, an auxiliary brush rod 216, a scraper strip 217, a guide block 218, and a wave groove 219. The motor 21 is fixedly connected to the inner wall of the machine body 1, and a reciprocating screw 22 is penetrated and rotatably connected to the surface of the machine body 1. When filtering the demulsifier, the motor 21 is started first, and then the demulsifier is poured into the machine body 1 through the feed hopper 4 and filtered through the filter screen 26. The output shaft of the motor 21 will drive the reciprocating screw 22 to rotate, and the end of the reciprocating screw 22 close to the motor 21 is fixedly connected to the output shaft of the motor 21, the baffle 25 is fixedly connected to the inner wall of the machine body 1, and the filter screen 26 is fixedly connected to the inner wall of the machine body 1. The end of the reciprocating screw 22 located inside the machine body 1 penetrates and is threadedly connected to a screw sleeve 27. Because the two groups of reciprocating screws 22 are symmetrically arranged, the screw sleeves 27 are symmetrically arranged. The connected connecting block 28 and the main brush rod 29 will limit the screw sleeve 27 relatively, so that the reciprocating screw rod 22 will not drive the screw sleeve 27 to rotate together when rotating, but make the screw sleeve 27 reciprocate along the reciprocating screw rod 22. The surface of the screw sleeve 27 is fixedly connected with the connecting block 28, and the end of the connecting block 28 away from the screw sleeve 27 is fixedly connected with the main brush rod 29. The bottom surface of the main brush rod 29 is fixedly connected with a brush 210. When the screw sleeve 27 reciprocates, the main brush rod 29 will be driven by the connecting block 28 to clean the filter screen 26, so as to avoid the impurities contained in the demulsifier from accumulating on the filter screen 26 when filtering the demulsifier, causing the filter screen 26 to be blocked and lose the filtering effect. The screw sleeve 27 is penetrated by a linkage block 211, and a slide groove 212 is provided on the inner side of the linkage block 211. The surface of the screw sleeve 27 is fixedly connected with a slider 213, and the slider 213 penetrates the slide groove 212. The top and bottom surfaces of the slider 213 are fixedly connected with springs 214, and the end of the spring 214 away from the slider 213 is fixedly connected to the inner side of the slide groove 212. The inner wall of the body 1 is provided with a wave groove 219, and the side of the linkage block 211 close to the wave groove 219 is fixedly connected with a guide block 218. When the screw sleeve 27 slides back and forth, the linkage block 211 will be driven to move together through the slider 213, and when the linkage block 211 slides, it will drive the guide block 218 to slide together. Since the guide block 218 penetrates the wave groove 219, the guide block 218 will drive the linkage block 211 to swing up and down, and the guide block 218 penetrates the wave groove 219 and is slidably connected. There are two groups of linkage blocks 211, and a connecting strip 215 is fixedly connected between the two groups of linkage blocks 211.There are two groups of reciprocating screw rods 22, and the two groups of reciprocating screw rods 22 are located at one end outside the machine body 1 and penetrate and are fixedly connected with a transmission wheel 23, and the transmission wheel 23 penetrated by the left reciprocating screw rod 22 and the transmission wheel 23 penetrated by the right reciprocating screw rod 22 are connected through a transmission belt 24, and the reciprocating screw rod 22 will drive the other group of reciprocating screw rods 22 to rotate through the transmission wheel 23 and the transmission belt 24. The left side of the linkage block 211 is fixedly connected with a secondary brush rod 216, and the guide block 218 will drive the linkage block 211 to swing up and down, causing the slider 213 to slide relatively in the slide groove 212, so that the spring 214 is repeatedly compressed and then bounces the slider 213 to reset, and when the linkage block 211 swings up and down, it will drive the secondary brush rod 216 to move up and down together, and the bottom surface of the secondary brush rod 216 is fixedly connected with a scraper strip 217.

[0024] Based on the above embodiment, when filtering the demulsifier, the motor 21 is started first, and then the demulsifier is poured into the machine body 1 through the feed hopper 4 and filtered through the filter screen 26. The output shaft of the motor 21 will drive the reciprocating screw rod 22 to rotate, and the reciprocating screw rod 22 will drive another set of reciprocating screw rods 22 to rotate through the transmission wheel 23 and the transmission belt 24. At the same time, because the two sets of reciprocating screw rods 22 are symmetrically arranged, the connecting block 28 and the main brush rod 29 connected between the screw sleeves 27 will relatively limit the screw sleeves 27, so that the reciprocating screw rod 22 will not drive the screw sleeve 27 to rotate together when rotating, but make the screw sleeve 27 reciprocate along the reciprocating screw rod 22. When the screw sleeve 27 reciprocates, it will drive the main brush rod 29 to clean the filter screen 26 through the connecting block 28, so as to avoid the accumulation of impurities contained in the demulsifier on the filter screen 26 when filtering the demulsifier, causing the filter screen 2 6 is blocked and loses the filtering effect. At the same time, when the screw sleeve 27 slides back and forth, the slider 213 drives the linkage block 211 to move together. When the linkage block 211 slides, it drives the guide block 218 to slide together. Since the guide block 218 penetrates the wave groove 219, the guide block 218 drives the linkage block 211 to swing up and down, causing the slider 213 to slide relatively in the slide groove 212, so that the spring 214 is repeatedly compressed and then the slider 213 is reset. When the linkage block 211 swings up and down, it drives the auxiliary brush rod 216 to move up and down together. The scraper bar 217 fixedly connected to the bottom of the auxiliary brush rod 216 not only scrapes the surface of the filter screen 26 back and forth to ensure the filtering effect of the filter screen 26, but also cleans the brush 210 at the bottom of the main brush rod 29 to avoid excessive impurities adhering to the brush 210 when the brush 210 cleans the filter screen 26.

[0025] When the linkage block 211 swings up and down, it will drive the scraper bar 217 at the bottom of the auxiliary brush rod 216 to knock on the filter screen 26, which can play an auxiliary role in cleaning the brush 210 and the filter screen 26, and can also break up the agglomerated or flocculent demulsifier to prevent the agglomerated demulsifier from being effectively filtered.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
