Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to a squeeze-type filter barrel. Background Technology

[0002] When centrifugation cannot achieve solid-liquid separation during experiments, filtration is often used. However, existing laboratory filtration methods simply involve filtering with filter cloth, which not only results in incomplete solid-liquid separation but also wastes staff time. Therefore, it is necessary to use filter press equipment driven by electric push rods or hydraulic rods to improve filtration efficiency and effect.

[0003] However, traditional pressure filtration equipment only uses a pressure plate that matches the inner diameter of the filter cylinder for compression. During the compression filtration process, the pressure plate and the top of the material inside the filter cylinder remain relatively stationary. When there is a large amount of filtrate, it is difficult to effectively suppress the naturally formed gaps inside the filtrate, resulting in some filtrate not being completely discharged, which affects the accuracy of experimental measurement data. To address this, we propose a compression-type filter cylinder. Utility Model Content

[0004] The purpose of this invention is to provide a compression filter barrel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a compression filter barrel, comprising a base, a collection barrel mounted on the upper surface of the base, a clamp fixedly mounted on the inner wall of the collection barrel, a filter cylinder fixed by the clamp, and a drain valve fixedly mounted on the bottom side wall of the collection barrel.

A fixing cylinder is fixedly mounted on the lower surface of the top frame, and a guide ball is fixedly mounted on the inner wall of the side of the fixing cylinder. The guide ball slides in cooperation with the spiral groove and the vertical groove.

[0006] Preferably, the inner wall of the cylindrical block has an inner sliding groove, the inner surface of the inner sliding groove is slidably connected to an inner protrusion, the side wall of the inner protrusion is fixedly connected to a transmission ring, the bottom end of the transmission ring is fixedly connected to a lower pressure plate, the upper surface of the lower pressure plate has a circular groove adapted to the upper pressure plate, the inner surface of the circular groove has an outer sliding groove, the side wall of the upper pressure plate is fixedly installed with an outer protrusion, the inner surface of the transmission ring has a wave groove, and the movable end side wall of the telescopic rod is fixedly installed with a convex ball, the convex ball slidingly engaging with the wave groove.

[0007] Preferably, the outer wall of the movable end of the telescopic rod is provided with a ring, and the inner surface of the cylindrical block is provided with an annular groove that matches the size of the ring, and the ring is disposed in the annular groove.

[0008] Preferably, the outer diameter of the sleeve is adapted to the inner diameter of the fixed cylinder, and the sleeve is disposed on the outside of the cylindrical block.

[0009] Preferably, the inner diameter of the transmission ring is adapted to the outer diameter of the movable end of the telescopic rod, and an annular cavity adapted to the outer diameter of the transmission ring is formed on the inner wall of the bottom of the cylindrical block.

[0010] Preferably, there are two sets of inner protrusions and inner grooves, as well as two sets of outer protrusions and outer grooves, and the two sets of inner protrusions and inner grooves and outer protrusions and outer grooves are symmetrically arranged with the vertical central axis of the telescopic rod as the axis of symmetry.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Under the drive of the hydraulic cylinder, the movable end of the telescopic rod moves downward together with the cylindrical block and the upper pressure plate. With the cooperation of the spiral groove, the fixed cylinder and the guide ball, the sleeve will both rotate and slide relative to the fixed cylinder, causing the upper pressure plate to continuously rotate and squeeze downward after contacting the pressurized mixture. The wave groove in the transmission ring will be affected by the convex ball, driving the transmission ring and the lower pressure plate to move up and down.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6The diagram shows a compression filter barrel, including a base 1, a collection barrel 2 mounted on the upper surface of the base 1, a clamp 3 fixedly mounted on the inner wall of the collection barrel 2, a filter cylinder 4 fixed by the clamp 3, and a drain valve 5 fixedly mounted on the bottom side wall of the collection barrel 2. A vertical rod 6 is fixedly mounted on the upper surface of the base 1, a top frame 7 is fixedly mounted on the top of the vertical rod 6, a hydraulic cylinder 8 is fixedly mounted on the upper end of the top frame 7, a telescopic rod 9 is fixedly mounted on the lower surface of the top frame 7, a cylindrical block 10 is rotatably connected to the outer wall of the movable end of the telescopic rod 9, an upper pressure plate 11 is fixedly mounted on the outer wall of the cylindrical block 10, a sleeve 12 is fixedly mounted on the upper surface of the upper pressure plate 11, a spiral groove 13 is opened on the side of the sleeve 12, and a vertical groove 14 is opened on the bottom side of the sleeve 12 and communicates with the bottom end of the spiral groove 13. A fixed cylinder 15 is fixedly mounted on the lower surface of the top frame 7, and a guide ball 16 is fixedly mounted on the inner wall of the side of the fixed cylinder 15. The guide ball 16 slides with the spiral groove 13 and the vertical groove 14.

[0022] There are four sets of vertical rods 6, arranged in a matrix array between the base 1 and the top frame 7. Simultaneously, there are multiple clamps 3 arranged in a circular array on the inner surface of the collection bucket 2, providing a fixing force for the filter cylinder 4 from the bottom and sides. Specifically, in actual use, the filter cloth is wrapped around the bottom of the filter cylinder 4, and sufficient space is reserved at the top of the clamps 3 to install clamps for fixing the filter cloth. During installation, the filter cloth is first wrapped around the bottom surface of the filter cylinder 4, and then the filter cylinder 4 is fixed inside the collection bucket 2, thus achieving the effect of fixing the filter cloth from both the inside and outside, avoiding severe deformation of the filter cloth during the pressure filtration process, which would affect normal use. It is worth noting that several filter holes are opened on the bottom inner wall of the filter cylinder 4 to facilitate filtration operations.

[0023] Furthermore, the telescopic rod 9 includes a fixed end and a movable end. The top surface of the fixed end is fixedly installed on the inner wall of the top frame 7, while the movable end is movably connected to the bottom inner wall of the fixed end. The output end of the hydraulic cylinder 8 passes through the top of the fixed end and the movable end and is fixedly connected. Under the drive of the hydraulic cylinder 8, the movable end and the fixed end of the telescopic rod 9 will undergo relative displacement to achieve extension and shortening, thereby realizing the pressure filtration operation of the material in the filter cylinder 4.

[0024] The outer wall of the movable end of the telescopic rod 9 is provided with a ring, and the inner surface of the cylindrical block 10 is provided with an annular groove that matches the size of the ring, and the ring is placed in the annular groove.

[0025] Please see Figures 3 to 4 Through the cooperation of the ring and the annular groove, the movable end of the telescopic rod 9 can drive the cylindrical block 10 to slide in the vertical direction, while there is no interference in the horizontal rotation between the two. That is, the cylindrical block 10 can rotate relative to the movable end of the telescopic rod 9.

[0026] The outer diameter of the sleeve 12 is adapted to the inner diameter of the fixed cylinder 15, and the sleeve 12 is located on the outside of the cylindrical block 10.

[0027] During the downward movement of the movable end of the telescopic rod 9 driven by the hydraulic cylinder 8, the upper pressure plate 11, the cylindrical block 10, and the sleeve 12 slide relative to the fixed cylinder 15 fixedly installed on the lower surface of the top of the top frame 7. Due to the fixed position of the guide ball 16 in the vertical direction, the guide ball 16 will move upward along the bottom of the vertical groove 14. At this time, the fixed cylinder 15 and the sleeve 12 only slide relative to each other in the vertical direction. Once the guide ball 16 enters the spiral groove 13, due to the guidance and restriction of the spiral groove 13, the sleeve 12 will rotate relative to the fixed cylinder 15 while moving relative to each other in the vertical direction. This will cause the upper pressure plate 11 to rotate and squeeze downward after contacting the pressurized mixture, thereby improving the pressure filtration effect of the pressurized mixture and reducing the residue in the gaps of the filtered material.

[0028] The inner wall of the cylindrical block 10 has an inner groove 20. The inner surface of the inner groove 20 is slidably connected to an inner protrusion 19. The side wall of the inner protrusion 19 is fixedly connected to a transmission ring 17. The bottom end of the transmission ring 17 is fixedly connected to a lower pressure plate 18. The upper surface of the lower pressure plate 18 has a circular groove that matches the upper pressure plate 11. The inner surface of the circular groove has an outer groove 22. The side wall of the upper pressure plate 11 is fixedly installed with an outer protrusion 21. The inner surface of the transmission ring 17 has a wave groove 23. The movable end side wall of the telescopic rod 9 is fixedly installed with a convex ball 24. The convex ball 24 slides in cooperation with the wave groove 23.

[0029] Please refer to Figures 5 to 6 The inner groove 20 is used to guide the inner protrusion 19 and the transmission ring 17. Similarly, the outer groove 22 is used to guide and restrict the outer protrusion 21, so that the upper pressure plate 11 and the lower pressure plate 18 can only move relative to each other in the vertical direction, and there will be no relative rotation.

[0030] The inner diameter of the transmission ring 17 is adapted to the outer diameter of the movable end of the telescopic rod 9, and an annular cavity adapted to the outer diameter of the transmission ring 17 is provided on the bottom inner wall of the cylindrical block 10.

[0031] With the annular cavity, the transmission ring 17 and the telescopic rod 9 can slide relative to each other in the vertical direction and rotate relative to each other in the horizontal direction.

[0032] There are two sets of inner protrusions 19 and inner sliding grooves 20, as well as two sets of outer protrusions 21 and outer sliding grooves 22. The two sets of inner protrusions 19 and inner sliding grooves 20, as well as outer protrusions 21 and outer sliding grooves 22 are symmetrically arranged with the vertical central axis of the telescopic rod 9 as the axis of symmetry.

[0033] The two sets of mirrored inner protrusions 19 and inner grooves 20, as well as outer protrusions 21 and outer grooves 22, can ensure the stability of the upper pressure plate 11 and the lower pressure plate 18 when they move relative to each other in the vertical direction.

[0034] There are two sets of convex balls 24, which are mirror images of each other on both sides of the movable end of the telescopic rod 9. The grooves on both sides of the vertical central axis of the wave groove 23 are symmetrically arranged.

[0035] Two sets of convex balls 24 move in the slots inside the left and right sides of the corrugated groove 23. As the upper pressure plate 11 rotates with the sleeve 12, the lower pressure plate 18 will also rotate. At this time, the corrugated groove 23 inside the transmission ring 17 will be affected by the convex balls 24, driving the transmission ring 17 and the lower pressure plate 18 to move up and down. Thus, during the process of the upper pressure plate 11 being pressed downward by the movable end of the telescopic rod 9, the lower pressure plate 18 intermittently moves up and down, intermittently increasing and decreasing pressure, causing the filter material in the pressurized mixture to deform repeatedly up and down, thereby causing the small cavities inside to break and release the accumulated solution, so as to achieve a better filtration effect and avoid filtrate residue.

[0036] In this invention, during use, the filter cloth is first wrapped around the bottom of the filter cylinder 4 and tightened and fixed with clamps to adhere it to the bottom surface of the filter cylinder 4. Then, the filter cylinder 4 is fixedly installed inside the collection tank 2 using multiple sets of clamps 3. The mixed solution to be filtered is poured into the filter cylinder 4. Next, the hydraulic cylinder 8 is activated to drive the movable end of the telescopic rod 9 downwards. Due to the ring's movement on the cylindrical block 10, relative sliding occurs between the upper pressure plate 11, the cylindrical block 10, the sleeve 12, and the fixed cylinder 15. Since the guide ball 16 is fixed inside the fixed cylinder 15, it moves upwards along the bottom of the vertical groove 14 until it reaches the bottom of the guide cylinder 15. Ball 16 enters the spiral groove 13. Due to the guidance and restriction of the spiral groove 13, the sleeve 12 will both rotate and slide relative to the fixed cylinder 15. This causes the upper pressure plate 11 to rotate and squeeze downward after contacting the pressurized mixture. At the same time, the wave groove 23 in the transmission ring 17 will be affected by the convex ball 24, which will drive the transmission ring 17 and the lower pressure plate 18 to move up and down. As a result, the movable end of the telescopic rod 9 drives the upper pressure plate 11 to press down during the filtration process. The lower pressure plate 18 intermittently moves up and down to intermittently increase and decrease pressure, causing the filter material in the pressurized mixture to deform repeatedly up and down, accelerating the discharge of the solution in the filter material and improving the filtration effect of the device.
