[0005] Therefore, a convenient emulsion filtration device is proposed. Utility Model Content
[0006] In view of this, the present invention aims to provide a convenient emulsion filtration device to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial alternative.
[0007] The technical solution of this utility model embodiment is implemented as follows: A convenient emulsion filtration device includes a filter assembly supported on the ground by legs for filtering emulsion and a feeding assembly disposed above the filter assembly for storing and discharging emulsion. The feeding assembly includes a storage tank fixed to the top outer wall of the filter assembly by a bracket and a piston that is sealed and slidably fitted to the inner wall of the storage tank. The top of the storage tank is provided with an air nozzle communicating with the inner cavity of the storage tank. The air nozzle is connected to an air storage assembly through a pipeline. The bottom of the storage tank is fixed with an inlet pipe communicating with the inner cavity of the storage tank. A valve is connected to the end of the inlet pipe. The other end of the valve can be connected to an emulsion supply with power delivery. Another valve is provided at the bottom of the storage tank for connecting to the outlet of the filter assembly to control its opening and closing.
[0008] In some embodiments, scrapers are fixed above or on both sides of the piston, and the scrapers are in contact with the inner wall of the storage tank.
[0009] In some embodiments, the gas storage assembly includes a plurality of longitudinally arrayed pressure gas tanks fixed to the top outer wall of the filter assembly by a bracket.
[0010] In some embodiments, each of the pressure storage tanks is fixed to and connected to a push-to-open valve at its nozzle, and the other side of the multiple push-to-open valves is connected to the nozzle via a pipeline.
[0011] In some embodiments, the outer wall of the piston is fixed with a "U"-shaped frame, the outer wall of the "U"-shaped frame is slidably connected to the inner wall of the storage tank, and the other side wall of the "U"-shaped frame is fixed with a double inclined wedge block that cooperates with the limit of the press-to-open-close valve.
[0012] In some embodiments, the filtration assembly includes a filter housing fixed to the outer wall of the top of the support leg and a filter screen fixed inside the filter housing.

[0014] In some embodiments, the arc-shaped sleeve and the rotary valve are fastened with a spring on the outer wall of the opposite side of the guide rod.
[0015] The present invention has the following advantages due to the adoption of the above technical solution:
[0016] 1. A convenient emulsion filtration device, which stores the emulsion in a storage tank, applies pressure to the emulsion with a piston, and stores the air pressure when the storage tank is fed in by an air storage component. The air pressure applied to the piston and the downward pressure of the piston assist in the discharge of the emulsion, thereby ensuring sufficient and smooth discharge and ensuring filtration efficiency.
[0017] 2. A convenient emulsion filtration device, wherein the gas storage component is composed of multiple pressure gas storage tanks.

[0030] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] Example 1:
[0034] like Figure 1-7 As shown, a convenient emulsion filtration device includes a filter assembly 2 supported on the ground by a support leg 1 for filtering emulsion, and a feeding assembly 3 disposed above the filter assembly 2 for storing and discharging emulsion.
[0035] The feeding assembly 3 includes a storage tank 4 fixed to the top outer wall of the filter assembly 2 by a bracket 6 and a piston 5 that is sealed and slidably fitted to the inner wall of the storage tank 4. The top of the storage tank 4 is provided with an air nozzle 10 that communicates with the inner cavity of the storage tank 4. The air nozzle 10 is connected to an air storage assembly 9 through a pipeline. The bottom of the storage tank 4 is fixed with an inlet pipe 8 that communicates with the inner cavity of the storage tank 4. The end of the inlet pipe 8 is connected to a valve 7. The other end of the valve 7 can be connected to an emulsion supply with power delivery. The bottom of the storage tank 4 is also provided with a valve 7 for connecting to the outlet of the filter assembly 2 to control opening and closing.
[0036] When the device is in use, with the storage tank 4 empty, the piston 5 is located at the bottom inside the storage tank 4. At this time, the emulsion to be filtered can be transported to the inner cavity of the storage tank 4 through the feed pipe 8 via the valve 7 connected to the emulsion supply. Simultaneously, the piston 5 moves upward under fluid pressure. The gas in the inner cavity of the storage tank 4 above the piston 5 is squeezed into the gas storage component 9 through the air nozzle 10 and stored, generating gas pressure. During this process, the valves connected to the filter component 2 and the feed component 3 are closed until the maximum storage capacity of the storage tank 4 is reached, at which point the valve 7 is closed and then the valves connected to the filter component 2 and the feed component 3 are opened. At this time, the gas stored in the gas storage component 9 generates pressure that acts in the opposite direction on the piston 5, causing the piston 5 to be subjected to downward pressure. Thus, the downward pressure of the piston 5 is used to push the emulsion in the inner cavity of the storage tank 4 downward, achieving stable feeding.
[0037] This device uses a storage tank 4 to store the emulsion, a piston 5 to apply pressure to the emulsion, and an air storage component 9 to store the air pressure when the storage tank 4 is fed. By applying air pressure to the piston 5 and then using the downward pressure of the piston 5 to assist the discharge of the emulsion, the device ensures sufficient and smooth discharge and guarantees filtration efficiency.
[0038] In this embodiment, scrapers 11 are fixed above or on both sides of the piston 5, and the scrapers 11 are in contact with the inner wall of the storage tank 4.
[0039] The scraper 11 can further scrape the material, which on the one hand prevents the emulsion from sticking to the inner wall of the storage tank 4, increasing the convenience of subsequent cleaning, and on the other hand prevents hard solid impurities mixed in the emulsion from entering the sealing surface of the storage tank 4 and the piston 5 and causing scratches, thus increasing reliability.
[0040] In this embodiment, the gas storage assembly 9 includes multiple longitudinally arrayed pressure gas storage tanks 14 fixed to the top outer wall of the filter assembly 2 by a bracket 2 16. Each pressure gas storage tank 14 has a press-to-open valve 15 fixed and connected at its nozzle. The other side of the multiple press-to-open valves 15 is connected to the gas nozzle 10 through a pipeline. The outer wall of the piston 5 is fixed with a "U"-shaped frame 12. The outer wall of the "U"-shaped frame 12 is slidably connected to the inner wall of the storage tank 4 in a sealed manner. The other side wall of the "U"-shaped frame 12 is fixed with a double inclined wedge block 13 that cooperates with the press-to-open valve 15 for limiting.
[0041] During the gas storage process, the piston 5 is initially located at the bottom of the storage tank 4, and the double-sloped wedge 13 is also at the bottom. The double-sloped wedge 13 engages with the bottommost press-on / off valve 15, pressing it to make it connected. At the same time, the other press-on / off valve 15 is disconnected because it does not engage with the double-sloped wedge 13. When the piston 5 moves upward, the gas in the upper cavity of the storage tank 4 first enters the bottommost pressure storage tank 14. As the piston 5 rises, the double-sloped wedge 13 also rises until it engages with the next press-on / off valve 15. The next pressure storage tank 14 then connects with the storage tank 4 to store gas. This process continues until the topmost pressure storage tank 14 connects with the storage tank 4 to store gas. The gas release process is the reverse of the gas storage process.
[0042] In this device, the gas storage component 9 is composed of multiple pressure gas storage tanks 14. On the one hand, it can store gas in stages, reducing the maximum gas pressure in each pressure gas storage tank 14, thereby reducing the resistance of the emulsion entering the storage tank 4. On the other hand, the multiple pressure gas storage tanks 14 release gas in stages to assist in the discharge, so that the pressure difference is relatively small during the entire process of exhausting gas by air pressure, thereby making the difference in discharge speed relatively small and ensuring the relative stability of the discharge speed.
[0043] This device, by setting a press-to-open / close valve 15, serves as a control component for connecting the pressure storage tank 14 and the storage tank 4. It also receives the vertical displacement of the piston 5 and the limiting effect of the double inclined wedge block 13 on the press-to-open / close valve 15, thereby enabling the opening and closing process of multiple press-to-open / close valves 15 to be fully automated as the piston 5 rises and falls.
[0044] In this embodiment, the filter assembly 2 includes a filter shell 17 fixed to the top outer wall of the support leg 1 and a filter screen 18 fixed inside the filter shell 17. When the emulsion enters from the top of the filter shell 17 and passes through the filter screen 18, the filter screen 18 can filter the solid particles in the emulsion. The filtered emulsion is then discharged from the bottom of the filter shell 17.
[0045] In this embodiment: When the storage tank 4 is empty, the piston 5 is located at the bottom inside the storage tank 4. At this time, the emulsion to be filtered can be transported to the inner cavity of the storage tank 4 through the feed pipe 8 via the valve 7 connected to the emulsion supply. At the same time, the piston 5 moves upward under fluid pressure. The gas in the inner cavity of the storage tank 4 above the piston 5 is squeezed into the gas storage component 9 through the air nozzle 10 and stored and generated gas pressure. During this process, the valve connected to the filter component 2 and the feed component 3 is closed until the maximum storage capacity of the storage tank 4 is reached. Then the valve 7 is closed and the valve connected to the filter component 2 and the feed component 3 is opened. At this time, the gas stored in the gas storage component 9 generates pressure and acts in the opposite direction on the piston 5, so that the piston 5 is subjected to downward pressure. Thus, the downward pressure of the piston 5 is used to push the emulsion in the inner cavity of the storage tank 4 downward, thereby achieving stable feeding. In addition, during the gas storage process, since the piston 5 is at the bottom of the storage tank 4, the double-sloped wedge 13 is also at the bottom. The double-sloped wedge 13 is in a limiting cooperation with the bottommost press-on / off valve 15, pressing the bottommost press-on / off valve 15 to make it in a connected state. At the same time, the press-on / off valve 15 is in a disconnected state because it is not in cooperation with the double-sloped wedge 13. When the piston 5 moves upward, the gas in the upper cavity of the storage tank 4 will first enter the bottommost pressure storage tank 14. As the piston 5 rises, the double-sloped wedge 13 also rises until it cooperates with the next press-on / off valve 15. The next pressure storage tank 14 is connected to the storage tank 4 to realize gas storage. After reaching the top, the topmost pressure storage tank 14 is connected to the storage tank 4 to store gas. The gas release process is the reverse of the gas storage process.
[0046] Example 2:
[0047] An easy-to-use emulsion filtration device is provided in this embodiment, which is based on Embodiment 1 with the following improvements, such as... Figure 7 As shown, the press-to-open / close valve 15 includes a rotary open / close valve 19 and an arc-head sleeve 24 that is slidably connected to the outer wall of the valve stem of the rotary open / close valve 19 via a guide rod 22. The inner wall of the arc-head sleeve 24 is provided with a spiral groove 23, and the outer wall of the valve stem of the rotary open / close valve 19 is fixed with a limiting protrusion 20 that is in movable limiting cooperation with the spiral groove 23.
[0048] In this embodiment, the arc head sleeve 24 and the rotary valve 19 are fastened with a spring 21 on the outer wall of the opposite side of the guide rod 22.
[0049] In this embodiment, the specific type of rotary valve 19 is not limited. It is a conventional valve that uses the rotation of the valve stem to control opening and closing. This is conventional knowledge and method for those skilled in the art, and this embodiment has not made any creative effort in it, so it will not be described in detail.
[0050] In this embodiment: when the arc head sleeve 24 is pressed towards the rotary valve 19 by contacting and engaging with the double inclined wedge block 13, the arc head sleeve 24 moves. Since the arc head sleeve 24 is limited by the guide rod 22 on both sides and cannot rotate relative to the rotary valve 19, the valve stem of the rotary valve 19 is rotated by the cooperation of the limiting protrusion 20 and the spiral groove 23, and the rotary valve 19 is in the open state. When the limitation on the arc head sleeve 24 disappears, the arc head sleeve 24 slides outward by the elastic force of the spring 21, thereby causing the valve stem of the rotary valve 19 to rotate in the opposite direction and the rotary valve 19 to close.
[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
