Description

Technical Field

[0001] The invention relates to a slurry recovery device, in particular to a capsule filter element slurry recovery system. Background Art

[0002] Capsule filters are also called integrated filters. They use a wound imported filter membrane with a large filtering surface area, which is suitable for filtering larger volume solutions. After long-term use, the filter element needs to be replaced. However, at this time, there is often still some residual material in the filter element that has been processed before. If this part of the residual material is not processed, it will not only increase the later processing cost of the filter element, but also cause waste of residual material.

[0003] The traditional method is to poke open the inlet and outlet of the filter element so that the fluid inside the filter element can automatically flow down and discharge under the action of gravity. However, the recovery efficiency of this method is very low. At the same time, due to the strong viscosity of the fluid, the slurry recovery is often not clean enough. Therefore, the existing technology connects the negative pressure extraction equipment directly to the inlet and outlet of the filter element, and extracts the fluid in the filter element by means of negative pressure extraction, which greatly increases the speed of the fluid flowing down the filter element. However, in the foldable filter element, the filter membranes are formed in a winding manner, which causes the filter membranes to be tightly attached to each other. It is difficult to completely recover the fluid in a short time by suction alone. If the time is delayed for a long time, some of the fluid will be lost due to its volatility.

[0004] Therefore, this case aims to provide a capsule filter element slurry recovery system, which can not only provide assistance for the external recovery of the fluid through normal suction at the lower end, but also improve the fluidity of the fluid in the wound filter membrane at the top and middle positions, thereby promoting higher fluid recovery efficiency. Summary of the invention

[0009] The middle shaking structure includes a lateral vibration member arranged on the outer side of the capsule filter element, and a bottom vibration member is arranged at the bottom of the capsule filter element. When the pressure triggering member is introduced into the external gas, the lateral vibration member and the bottom vibration member on the capsule filter element drive the capsule filter element to shake, so that the fluid in the capsule filter element is discharged downward;

[0010] The bottom movable structure includes a restraining sleeve arranged in the middle section of the accommodating cavity, the liquid inlet column and the liquid outlet column of the capsule filter element are inserted into the restraining sleeve, the outer movable clamp of the restraining sleeve is provided with a tightening piece, and a movable piece is provided at the bottom of the accommodating cavity, and a ejector pin is installed in the movable piece. When the capsule filter element is inserted into the restraining sleeve, the restraining sleeve and the tightening piece are clamped on the outer sides of the liquid inlet column and the liquid outlet column, and the ejector pin is inserted into the liquid inlet column and the liquid outlet column.

[0011] As a further improvement, a square locking plate is provided on the outer side of the outer fixing sleeve, and the outer fixing sleeve is fixed to the base through the locking plate.

[0012] As a further improvement, a transverse frame is provided on the output end of the cylinder, and the pressure trigger includes a control end movably connected to the transverse frame, the control end is connected to a transmission pipeline, and the transmission pipeline is connected to a pressure pump.

[0013] As a further improvement, the control end is a manual control valve plate, or the control end is an electric control valve.

[0014] As a further improvement, the lateral vibration member includes an inner bonding block glued to the outer side of the capsule filter element, a side rocking spring is arranged on the outer side of the inner bonding block, and the side rocking spring is locked to the inner wall of the outer fixing sleeve through an outer fixing block.

[0015] As a further improvement, the bottom vibration member includes an oblique mounting block fixedly connected to the base, the oblique mounting block is provided with an oblique support spring, the upper end of the oblique support spring is provided with an oblique top block, and the oblique top block supports the bottom surface of the capsule filter element.

[0016] As a further improvement, the restraint sleeve includes a transverse restraint section fixed to the inner side wall of the accommodating cavity, and a longitudinal restraint section connected to the lower end of the transverse restraint section and integrally formed, and the transverse restraint section and the longitudinal restraint section are attached to the outer sides of the liquid inlet column and the liquid outlet column of the capsule filter element.

[0017] As a further improvement, the clamping member includes an elastic arc ring arranged on the outside of the longitudinal restraining section, the outside of the elastic arc ring is connected to an elastic rod, and the elastic rod is fixed to the inner wall of the accommodating cavity.

[0018] As a further improvement, the movable part includes a revolving ring arranged at the bottom of the accommodating cavity, a movable button is arranged on the inner side of the revolving ring, and the ejector pin is inserted into the movable button.

[0019] As a further improvement, the top surface of the ejector pin is flexibly connected to the liquid inlet column and the liquid outlet column, and the swing amplitude of the ejector pin is less than 10°.

[0020] The beneficial effects of the present invention are:

[0021] Conventional filter element recovery devices all use negative pressure only at the bottom. Although this can also achieve the purpose of extracting the fluid in the filter element, the recovery efficiency is very slow, which can easily lead to fluid volatilization and waste, and also affect the recovery progress. Therefore, the present invention sets a top material passing structure. After the capsule filter element is fixed, the pressure trigger is inserted into the connecting air column of the capsule filter element through the cylinder, and pressure is applied through the position of the top connecting air column. The fluid between the filter membranes is squeezed downward by the inert gas that does not react with the fluid, so that the fluid discharge speed becomes faster, thereby improving the overall recovery efficiency of the filter element. After recovering a single filter element, the pressure trigger can be directly lifted up again by the cylinder, so that the filter elements can be processed in batches and quickly, which on the one hand reduces the processing cost, and on the other hand improves the utilization of waste materials.

[0022] In order to fix the basic position of the entire capsule filter element during vacuuming and avoid unrestricted positional deviation of the capsule filter element, the present invention locks the external fixing sleeve onto the base, so that the middle shaking structure can be arranged on the inner side of the external fixing sleeve. After the single filter element is processed, the external fixing sleeve and the base can be separated, which can ensure stable connection and separability, thereby facilitating the replacement of the filter element.

[0023] After separating the outer fixing sleeve and the base, the pressure trigger needs to be separated from the capsule filter element so that the capsule filter element can be taken out and replaced with a new one for recycling. Therefore, the present invention connects the control end of the pressure trigger element to the transverse moving frame of the cylinder. When the filter element is in the recycling stage, the control end is moved down by the cylinder, and when the filter element is completely recycled, the control end is lifted up by the cylinder to achieve position switching of the control end, thereby improving the practical effect of the present invention.

[0024] Since the filter membranes are all rolled together, the gaps between the membranes are small. Although the top ventilation has a certain effect, the actual effect is small. Therefore, the present invention arranges a middle shaking structure based on the top material passing structure. By utilizing the vibration of the filter membrane and the vibration of the entire filter element housing when the gas is passed through the top material passing structure, the entire capsule filter element is movably installed through the lateral vibration member and the bottom vibration member. When the gas is passed, the entire filter element shakes, and the shaking amplitude is larger under the action of the lateral vibration member and the bottom vibration member, thereby making the fluid discharge speed faster and being able to process more filter elements in a short time.

[0025] The lateral vibration member is not fixedly arranged, otherwise it would be difficult to separate and handle during the capsule filter element insertion and removal stage. Therefore, the lateral vibration member of the present invention is first fixed to the capsule filter element through an internal adhesive block, and after the external fixing sleeve is installed, the external fixing block is locked through the outside of the external fixing sleeve, thereby achieving the effect of fixed connection at both ends but detachable at one end.

[0026] The bottom vibration piece is not set in a forward direction, but is set in an inclined manner to slightly support the capsule filter element. The inclined top block can be supported at the lower end of the capsule filter element and change direction as the capsule filter element changes direction, which can enable the capsule filter element to achieve the effect of changing direction while avoiding tilting at too large an angle to avoid the phenomenon of being unable to reset.

[0027] If the entire capsule filter element shakes, it is obviously not possible to set only the outer side of the capsule filter element to an active state, and the bottom of the capsule filter element must also be set to an active state. Therefore, the present invention sets a bottom active structure based on the middle shaking structure. First, the liquid inlet column and the liquid outlet column of the capsule filter element are movably fixed by an adaptable binding sleeve and a clamping member to ensure active assembly while providing a certain left and right limiting effect. The bottom ejector pin is also set in the movable part to achieve an adjustable position of the ejector pin, so that the main body of the entire capsule filter element and the bottom connecting part can be made into an active setting to adapt to the vibration effect brought by the introduced gas and achieve an improvement in the overall recovery efficiency.

[0028] Since the sizes of the liquid inlet column and the liquid outlet column of different capsule filter elements may be different, it is difficult to set the size of the bottom movable structure. Therefore, the restraint sleeve of the present invention adopts a two-stage movable tight-binding design. Regardless of the size of the inserted pipe column, the transverse restraint section and the longitudinal restraint section can be stretched to achieve flexible restraint of the liquid inlet column and the liquid outlet column. At the same time, the outer side of the longitudinal restraint section is also supplemented by a clamping member to limit it laterally to improve its adaptability.

[0029] The movable setting of the bottom makes it impossible to set the ejector pin in a fixed installation mode. Therefore, the ejector pin of the present invention is movably installed on the movable part. The ejector pin rotates along the movable button during the movement of the liquid inlet column and the liquid outlet column of the capsule filter element, thereby realizing the position change. Moreover, the bottom is not affected because it is connected to the negative pressure extraction device through a hose. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0043] Reference Figures 1 to 8As shown, a capsule filter element slurry recovery system is used to recover the fluid in the capsule filter element 10, including a base 20 for receiving the capsule filter element 10, and the lower end of the base 20 is provided with two accommodating chambers 21 for accommodating the capsule filter element 10. The capsule filter element slurry recovery system also includes: a top material passing structure, including an external fixing sleeve 31 sleeved on the outside of the capsule filter element 10, a pressure trigger 32 is arranged on the top of the external fixing sleeve 31, and the pressure trigger 32 is plugged into the connecting air column of the capsule filter element 10. The pressure trigger 32 is driven by a cylinder 33, and the bottom of the cylinder 33 extends to the external fixing sleeve 31. When the capsule filter element 10 is installed on the base 20, the external fixing sleeve 31 is sleeved on the outside of the capsule filter element 10 and the pressure trigger 32 is plugged into the capsule filter element 10; a middle shaking structure 40, including a middle shaking structure 40, which is arranged on the capsule filter element 10 has a lateral vibration member 41 on the outer side surface, and a bottom vibration member 42 is arranged at the bottom of the capsule filter element 10. When the pressure-trigger member 32 is introduced into the external gas, the lateral vibration member 41 and the bottom vibration member 42 on the capsule filter element 10 drive the capsule filter element 10 to shake, so that the fluid in the capsule filter element 10 is discharged downward; the bottom movable structure 50 comprises a restraining sleeve 51 arranged in the middle section of the inner part of the accommodating chamber 21, the liquid inlet column and the liquid outlet column of the capsule filter element 10 are plugged into the restraining sleeve 51, and a clamping member 52 is clamped on the outer side of the restraining sleeve 51. A movable member 53 is arranged at the bottom of the accommodating chamber 21, and a ejector pin 54 is installed in the movable member 53. When the capsule filter element 10 is inserted into the restraining sleeve 51, the restraining sleeve 51 and the clamping member 52 are clamped on the outer sides of the liquid inlet column and the liquid outlet column, and the ejector pin 54 is inserted into the liquid inlet column and the liquid outlet column.

[0044] When in use, the inert gas introduced into the capsule filter element 10 will not react with the fluid in the filter element, while being able to play a boosting role.

[0045] Conventional filter element recovery devices all use only the method of drawing negative pressure at the bottom. Although it can also achieve the purpose of extracting the fluid in the filter element, the recovery efficiency is very slow, which can easily lead to fluid volatilization and waste, and also affect the recovery progress. Therefore, this embodiment uses a top material passing structure to insert the pressure trigger 32 into the connecting air column of the capsule filter element 10 through the cylinder 33 after the capsule filter element 10 is fixed, and pressure is applied through the position of the top connecting air column. The inert gas that does not react with the fluid squeezes the fluid between the filter membranes downward, so that the fluid discharge speed becomes faster, thereby improving the overall recovery efficiency of the filter element, and after recovering a single filter element, the pressure trigger 32 can be directly lifted up again through the cylinder 33, so that the filter elements can be processed in batches and quickly, which on the one hand reduces the processing cost, and on the other hand improves the utilization of waste materials.

[0046] In order to fix the basic position of the entire capsule filter element 10 during vacuuming and prevent the position of the capsule filter element 10 from being shifted unrestricted, a square locking plate 311 is provided on the outer side of the outer fixing sleeve 31 of the present embodiment, and the outer fixing sleeve 31 is fixedly connected to the base 20 through the locking plate 311. By locking the outer fixing sleeve 31 to the base 20, the middle shaking structure 40 can be set to the inner side of the outer fixing sleeve 31. After the single filter element is processed, the outer fixing sleeve 31 and the base 20 can be separated, which can ensure stable connection and separability, so as to facilitate the replacement of the filter element.

[0047] After the outer fixing sleeve 31 and the base 20 are separated, the pressure trigger 32 needs to be separated from the capsule filter element 10 so that the capsule filter element 10 can be taken out and replaced with a new filter element for recycling. Therefore, a transverse frame 331 is provided on the output end of the cylinder 33 of this embodiment, and the pressure trigger 32 includes a control end 321 movably connected to the transverse frame 331, and the control end 321 is connected to a transmission pipe 322, and the transmission pipe 322 is connected to a pressure pump 323. By connecting the control end 321 of the pressure trigger 32 with the transverse frame 331 of the cylinder 33, when the filter element is in the recycling stage, the control end 321 is moved down by the cylinder 33, and when the filter element is recovered, the control end 321 is lifted up by the cylinder 33 to realize the position switching of the control end 321, thereby improving the practical effect of the present invention.

[0048] When the viscosity of the fluid in the filter element is less than 6000CP, the control end 321 of this embodiment is a manual control valve plate, which provides a switching force of 1 to 1.5KG. If the viscosity of the fluid in the filter element is greater than 6000CP, the control end 321 of this embodiment is an electric control valve, which provides a switching force of 2.5 to 3KG.

[0049] Since the filter membranes are all wound together, the gaps between the membranes are small. Although the top ventilation has a certain effect, the actual effect is small. Therefore, the present invention sets a middle shaking structure 40 on the basis of the top material passing structure. By utilizing the vibration of the filter membrane and the vibration of the entire filter element housing when the gas is passed through the top material passing structure, the entire capsule filter element 10 is movably installed through the lateral vibration member 41 and the bottom vibration member 42. When the gas is passed, the entire filter element shakes, and the shaking amplitude is larger under the action of the lateral vibration member 41 and the bottom vibration member 42, so that the fluid discharge speed is faster and more filter elements can be processed in a short time.

[0050] The lateral vibration member 41 of the present embodiment includes an inner bonding block 411 glued to the outside of the capsule filter element 10, and a side rocking spring 412 is arranged on the outside of the inner bonding block 411, and the side rocking spring 412 is locked to the inner wall of the outer fixing sleeve 31 through an outer fixing block 413. The lateral vibration member 41 is not fixedly arranged, otherwise it is difficult to separate and handle during the insertion and removal stage of the capsule filter element 10. Therefore, the lateral vibration member 41 of the present invention first fixes the entire lateral vibration member 41 on the capsule filter element 10 through the inner bonding block 411, and after the outer fixing sleeve 31 is installed, the outer fixing block 413 is locked through the outside of the outer fixing sleeve 31, thereby achieving the effect of fixed connection at both ends but detachable at one end.

[0051] The bottom vibration member 42 of the present embodiment includes an oblique mounting block 421 fixedly connected to the base 20, and an oblique supporting spring 422 is arranged on the oblique mounting block 421, and an oblique top block 423 is arranged at the upper end of the oblique supporting spring 422, and the oblique top block 423 supports the bottom surface of the capsule filter element 10. The bottom vibration member 42 is not arranged in a forward direction, but is arranged in an inclined manner to slightly support the capsule filter element 10. The oblique top block 423 can be supported at the lower end position of the capsule filter element 10, and change direction with the change of direction of the capsule filter element 10, which can not only enable the capsule filter element 10 to achieve the effect of changing direction, but also can avoid tilting at too large an angle to avoid the phenomenon of being unable to reset.

[0052] If the entire capsule filter element 10 shakes, it is obviously not possible to set only the outer side of the capsule filter element 10 to an active state, and the bottom of the capsule filter element 10 must also be set to an active state. Therefore, in this embodiment, a bottom active structure 50 is set on the basis of the middle shaking structure 40. First, the liquid inlet column and the liquid outlet column of the capsule filter element 10 are movably fixed by an adaptable binding sleeve 51 and a clamping member 52 to ensure active assembly while providing a certain left and right limiting effect. The bottom ejector pin 54 is also set in the movable part 53 to achieve an adjustable position of the ejector pin 54, so that the main body of the entire capsule filter element 10 and the bottom connecting part can be made into an active setting to adapt to the vibration effect brought by the introduced gas and achieve an improvement in the overall recovery efficiency.

[0053] Since the sizes of the liquid inlet column and the liquid outlet column of different capsule filter elements 10 may be different, it is difficult to set the size of the bottom movable structure 50. Therefore, the restraint sleeve 51 of this embodiment includes a transverse restraint section 511 fixed to the inner wall of the accommodating cavity 21, and a longitudinal restraint section 512 connected to the lower end of the transverse restraint section 511 and integrally formed. The transverse restraint section 511 and the longitudinal restraint section 512 are attached to the outer sides of the liquid inlet column and the liquid outlet column of the capsule filter element 10. The restraint sleeve 51 is a two-stage movable tight-binding design. No matter what the size of the inserted pipe column is, the transverse restraint section 511 and the longitudinal restraint section 512 can be stretched open to achieve flexible restraint of the liquid inlet column and the liquid outlet column. At the same time, the outer side of the longitudinal restraint section 512 is also supplemented by a clamping member 52 for lateral limitation. The clamping member 52 includes an elastic arc ring 521 arranged on the outer side of the longitudinal restraint section 512. The outer side of the elastic arc ring 521 is connected to an elastic rod 522. The elastic rod 522 is fixed to the inner wall of the accommodating cavity 21 to improve its adaptability.

[0054] The movable setting of the bottom means that the setting of the ejector pin 54 cannot be fixedly installed. Therefore, the ejector pin 54 of this embodiment is movably installed on the movable part 53. The movable part 53 includes a revolving ring 531 arranged at the bottom of the accommodating chamber 21. A movable button 532 is arranged on the inner side of the revolving ring 531. The ejector pin 54 is inserted into the movable button 532. The ejector pin 54 rotates along the movable button 532 during the movement of the liquid inlet column and the liquid outlet column of the capsule filter element 10, thereby realizing the change of position. In addition, the bottom is not affected because it is connected to the negative pressure extraction equipment through a hose.

[0055] In order to prevent the ejector pin 54 from being interfered with by the liquid inlet column and the liquid outlet column, the top surface of the ejector pin 54 is flexibly connected to the liquid inlet column and the liquid outlet column, and the swing amplitude of the ejector pin 54 is less than 10°.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
