[0027] The following is combined with Figure 1-4 The present application is further described in detail. An embodiment of the present application discloses an emulsifier filtering device.

[0028] Reference Figure 1 and Figure 2 As shown, an emulsifier filtering device includes a box 100, a filter assembly 200 and a drive assembly 300. The box 100 is provided with a filter chamber 110 with an opening at the top, and the filter chamber 110 is arranged in a rectangular shape and is vertically opened from top to bottom. The lower part of the box 100 is provided with a discharge port 120 with an opening at the bottom, and the discharge port 120 is connected to the filter chamber 110 from the upper end, and the discharge port 120 is arranged in a funnel shape, that is, the opening of the discharge port 120 is smaller than the opening of the filter chamber 110. This facilitates the one-time filtration of more emulsions and the collection of the filtered emulsion. The filter assembly 200 is arranged inside the box 100 and is located in the filter chamber 110, so as to facilitate the filtration of the emulsion. The side wall of the box 100 is penetrated with a slag outlet 130, and the slag outlet 130 is arranged obliquely, that is, the port of the slag outlet 130 located outside the box 100 is lower than the port of the slag outlet 130 located inside the box 100. The driving assembly 300 is installed on the housing 100 to provide power to the filtering assembly 200 .

[0029] Reference Figure 1 and Figure 2 As shown, the filter assembly 200 includes a sieve plate 210 and a second spring 240. A receiving groove 150 is provided on the width side wall of the box body 100. The notch of the receiving groove 150 is arranged opposite to the slag outlet 130. The top surface of the receiving groove 150 is arranged in an inclined manner, that is, the opening of the receiving groove 150 is larger than the bottom of the groove, so as to facilitate the installation of the sieve plate 210. The second spring 240 is installed in the receiving groove 150, one end of the second spring 240 is fixedly installed on the bottom of the receiving groove 150, and the other end of the second spring 240 is fixedly installed on the side wall of the sieve plate 210. The sieve plate 210 is arranged horizontally, and the other end of the sieve plate 210 is just located above the slag outlet 130 and blocks the opening of half of the slag outlet 130.

[0030] A U-shaped frame is disposed inside the box body 100 , and the sieve plate 210 is disposed against the frame.

[0031] The number of the second springs 240 in the embodiment of the present application can be increased according to usage.

[0032] Reference Figure 2 and Figure 3As shown, the filter assembly 200 further includes a baffle 280 and a first spring 230. The side wall of the box body 100 is provided with a groove 140 whose opening is located inside the box body 100. The groove 140 is arranged in an inclined manner, and the inclination direction of the groove 140 is parallel to the inclination direction of the slag outlet 130, and the groove 140 is located above the slag outlet 130. The baffle 280 is slidably arranged inside the groove 140, one end of the first spring 230 is fixedly connected to one side of the baffle 280, and the other end of the first spring 230 is fixedly connected to the bottom surface of the groove 140. In this way, the baffle 280 protrudes from the groove 140 under the action of the first spring 230, and the lower edge of the end thereof abuts against the screen plate 210, and the higher edge outside the baffle 280 protrudes above the screen plate 210. In this way, the screen plate 210 and the baffle 280 simultaneously block the slag outlet 130.

[0033] In addition, the baffle 280 can be just contracted into the groove 140 under external force.

[0034] The filter assembly 200 further includes two protrusions 250, which are fixedly connected to the side of the baffle 280 facing away from the first spring 230. The two protrusions 250 are symmetrically arranged, that is, the two protrusions 250 are arranged at the width sidewalls of the baffle 280, and the two protrusions 250 are extended from the inclined direction of the baffle 280. When the baffle 280 can be just contracted in the groove 140 under the external force, the two stoppers just abut against the sidewall ends of the sieve plate 210, and under the abutment of the stoppers, the sieve plate 210 is contracted into the receiving groove 150 and the second spring 240 is pressed.

[0035] As a result, the slag outlet 130 between the two stoppers is opened, thereby facilitating the discharge of the emulsion slag on the screen plate 210 .

[0036] Reference Figure 2 As shown, the filter assembly 200 also includes a scraper 220 and a brush 270. The scraper 220 is arranged inside the box 100, and the scraper 220 scrapes horizontally along the surface of the screen plate 210. The brush 270 is fixedly connected to the scraper 220 facing the side of the receiving groove 150, and the screen plate 210 is further cleaned by the brush 270.

[0037] When the scraper 220 is pushed by the driving assembly 300 and is pushed by one end of the screen plate 210 embedded in the receiving groove 150, it moves toward the slag outlet 130, so that the scraper 220 scrapes off the slag on the screen plate 210, and when the scraper 220 is close to the baffle 280, the scraper 220 preferentially pushes the two blocks, so that the lower edges of the two blocks abut the screen plate 210, push it to shrink in the receiving groove 150 and squeeze the second spring 240, and open the blockage of the slag outlet 130, so that the slag is discharged from the slag outlet 130.

[0038] The filter assembly 200 further includes a pressing plate 290 and a plurality of convex points 260. The plurality of convex points 260 are fixedly connected to the top of the sieve plate 210 in a uniform sliding direction of the scraper plate 220, and the convex points 260 are arranged close to the side wall of the sieve plate 210. The bottom surface of the sieve plate 210 is provided with a through slot 221 for passing the convex points 260. The scraper plate 220 is also provided with a receiving cavity 222 with an opening at the bottom, and the pressing plate 290 is sleeved in the receiving cavity 222. When the scraper plate 220 passes through the convex points 260, the convex points 260 pass through the through slot 221, and the pressing plate 290 located in the receiving cavity 222 is lifted along its arc surface under the obstruction of the convex points 260. When passing through the arc surface, it will fall on the sieve plate 210 under the action of its gravity, thereby starting a vibration effect on the slag on the sieve plate 210, facilitating the passage of the emulsion, and facilitating the scraping of the slag.

[0039] Reference Figure 1 and Figure 2 As shown, the driving assembly 300 includes an electric slide rail 310, an electric slider 320 and a roller 330. The electric slide rail 310 is fixedly connected to the top surface of the box 100. The electric slider 320 is slidably arranged on the electric slide rail 310 and fixedly connected to the side wall of the scraper 220. In this way, the scraper 220 slides horizontally driven by the electric slider 320. A slide groove 340 is also provided on the inner wall of the box 100. The roller 330 is rotatably installed on the side wall of the scraper 220, and the roller 330 rotates in the slide groove 340, so as to ensure the stability and smoothness of the scraper 220 during the movement.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
