Description

Technical Field

[0002] The quality and performance of the base of electronic products are directly related to the reliability and stability of the entire electronic product. In order to ensure its quality and performance, the surface needs to be plated. According to different design requirements, the plating methods and materials involved are different. As for the nickel plating layer, the nickel layer has excellent corrosion resistance and conductivity, which is very important for ensuring the service life and performance of the electronic product base. The chemical nickel plating method in nickel plating is a process in which nickel ions in an aqueous solution are reduced by a reducing agent under certain conditions and precipitated onto the surface of a solid substrate. The components in the nickel solution and their interactions, especially the co-deposition of nickel ions and carbon-containing organic matter, can easily cause black spots in the coating. In order to avoid this phenomenon, the nickel solution needs to be ultrafiltered.

[0003] After searching the invention patent with patent number CN116040748B, an ultrafiltration device for industrial water recovery is disclosed, which includes an outer cylinder and a filter membrane inner cylinder, the filter membrane inner cylinder is arranged inside the outer cylinder and the outer cylinder includes an upper cylinder, a lower cylinder and an intermediate connection part, the intermediate connection part includes an annular seat and two groups of top rods, both end surfaces of the annular seat have installation grooves, the two groups of top rods are respectively arranged inside the two installation grooves and the two groups of top rods extend into the inner side of the upper cylinder and the lower cylinder respectively, a group of elastic lateral clamps are arranged on the inner wall of the upper cylinder and the lower cylinder, and the end of the top rod away from the intermediate connection part has a top pressure block. The present invention has a simple structure, is easy to disassemble and replace the filter membrane inner cylinder, and can automatically clamp the filter membrane inner cylinder through the elastic lateral clamps when installing the outer cylinder, thereby improving the ability of clamping the filter membrane inner cylinder to resist industrial water impact, and improving the service life of the ultrafiltration device, which is more practical.

[0004] Based on the above patents and the existing solutions and the actual use process, the current nickel solution ultrafiltration device still has some problems, such as: 1. The existing ultrafiltration device is mainly composed of a filter cartridge and a filter element, which is the same as the above patent. The above patent mainly includes an outer cylinder and a filter membrane inner cylinder. When disassembling and replacing the filter membrane inner cylinder, since the liquid to be filtered is easily accumulated in the outer cylinder, the removal of the filter membrane inner cylinder will be accompanied by leakage of the liquid to be filtered. When the liquid to be filtered is a toxic chemical liquid, such as nickel solution, it is easy to affect the disassembly process or the disassembly personnel. However, the above patent and the existing ultrafiltration device cannot realize the recovery and treatment of the liquid accumulated in the filter cartridge, and cannot ensure that the filter element is disassembled without accumulated liquid; 2. The existing ultrafiltration device needs to be manually operated when removing and replacing the filter element. In the above patent, the elastic lateral clamping parts on the inner wall of the upper cylinder and the lower cylinder are needed to assist in manual operation when removing and replacing the filter element. Both operations are cumbersome, which affects the convenience of removal and replacement. Therefore, we propose a nickel solution ultrafiltration system to solve the above problems.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 10 The present invention provides a technical solution: a nickel solution ultrafiltration system, including a filter cartridge shell 1, a filter pressing mechanism 5 and a disassembly and replacement mechanism 6.

[0020] When the nickel solution ultrafiltration system is in use, the filter press mechanism 5 is arranged in the shell cavity of the filter cartridge shell 1, and is located on the same vertical central axis as the filter cartridge shell 1. The filter press mechanism 5 assists in the high-efficiency ultrafiltration operation of the nickel solution by reciprocating extrusion. Specifically, according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Fig. 9 As shown, the right side cover body of the top cover 2 is connected to a liquid inlet pipe of an integrated structure, wherein the liquid inlet pipe is sealed and fixedly connected to the nickel solution storage box. The nickel solution storage box is a prior art and is not described in the drawings of the specification. Since the filter cartridge shell 1 is arranged in a cylindrical structure, its upper port is in an open state, and a tube shell portion of an integrated structure is vertically downwardly arranged in the middle of the cover cavity of the top cover 2, and a sealing ring is fixedly clamped at the connection between the tube shell portion and the filter cartridge shell 1. After the top cover 2 is placed, its lower end is clamped at the upper port of the filter cartridge shell 1, and the tube shell portion is inserted into the upper shell cavity of the filter cartridge shell 1, and it is sealed and fixedly connected to the upper port of the filter cartridge shell 1 by bolts. Since an annular gap is reserved between the tube shell portion in the top cover 2 and its cover cavity opening, it is used for communication between the cover cavity in the top cover 2 and the shell cavity of the filter cartridge shell 1. The nickel solution enters its cover cavity through the liquid inlet pipe in the top cover 2, and then enters the shell cavity of the filter cartridge shell 1 through the annular gap in the top cover 2. Since the main pressure piece 7 is arranged in a circular tubular structure, its lumen is divided into two parts, a pumping chamber and a pressure chamber, from top to bottom by a partition wall therein. A sealing ring is fixedly clamped on the outer side of the upper end of the bottom end cover 3, and a gap is reserved between its upper section and the shell cavity wall of the filter cartridge shell 1. Since the maximum sliding distance of the main pressure piece 7 is smaller than the depth dimension of the gap between the bottom end cover 3 and the filter cartridge shell 1, after the main pressure piece 7 is installed, the wall of the pressure chamber is movably inserted in the gap between the bottom end cover 3 and the filter cartridge shell 1, and the sliding connection between the pressure chamber and the bottom end cover 3 is sealed by a sealing ring. After the nickel solution enters the shell cavity of the filter cartridge shell 1, it falls into the pumping chamber of the main pressure piece 7. Since the central position of the auxiliary pressure piece 8 is vertically upwardly provided with a sleeve portion of an integrated structure, the auxiliary pressure piece 8 is placed in the liquid extraction cavity of the main pressure piece 7 after being installed, and the sleeve portion is movably inserted in the shell cavity of the tube shell portion in the top cover 2, and since the first electric telescopic rod 10 is fixedly installed on the upper cover body of the top cover 2 by bolts after being installed, it is in a downward state and is on the same vertical central axis as the filter press mechanism 5, wherein the output end movably passes through the upper cover body of the top cover 2 and is inserted into the tube shell portion in the top cover 2, and wherein the output end is fixedly connected with the upper end of the sleeve portion in the auxiliary pressure piece 8 by bolts, and the first electric telescopic rod 10 is started to retract and operate, so that the sleeve portion in the auxiliary pressure piece 8 forms a sliding structure upward in the tube shell portion in the top cover 2; Since the outer side of the sleeve portion in the auxiliary pressure piece 8 is fixedly connected with a sealing ring at equal intervals, which fits with the tube shell portion in the top end cover 2, the sliding connection between the sleeve portion in the auxiliary pressure piece 8 and the tube shell portion in the top end cover 2 is sealed by the sealing ring. In addition, since the pin column portion 701 is movably inserted in the "L"-shaped locking groove 101 after being installed, and the bolt member 12 is movably inserted in the round groove 11 after being installed, the main pressure piece 7 is limited on the auxiliary pressure piece 8 through the sliding cooperation between the pin column portion 701 and the "L"-shaped locking groove 101, and through the cooperation between the bolt member 12 and the round groove 11. When the auxiliary pressure piece 8 is driven to slide upward, it drives the main pressure piece 7 to move synchronously, so that the main pressure piece 7 rises and slides in the shell cavity of the filter cartridge shell 1, wherein the cavity wall of the pressure liquid cavity slides against the upper section of the bottom end cover 3, and the pin column portion 701 slides along the longitudinal groove path in the "L"-shaped locking groove 101; Since the valve stem 13 for controlling the connection or closure of the liquid supply channel 801 is provided, the longitudinal section of the valve stem 13 is in a "convex" shape, divided into two parts, a wide part and a narrow part, and is in a vertical state after being installed, wherein the wide part is movably inserted in the groove cavity of the auxiliary pressure member 8, and the narrow part movably penetrates through the groove cavity wall and extends upward, so that the valve stem 13 is positioned on the auxiliary pressure member 8 in an active state, and since the lower section of the wide part of the valve stem 13 is provided with a spring chamber, the connection between the valve stem 13 and the auxiliary pressure member 8 is installed with a spring chamber. The return spring 14 is movably inserted in the spring compartment of the valve stem 13 after being installed, with one end of the return spring pressed against the wall of the spring compartment and the other end pressed against the wall of the groove cavity of the auxiliary pressure piece 8. After the auxiliary pressure piece 8 drives the valve stem 13 to slide upward, the narrow part of the valve stem 13 is connected to the lower side wall of the tube shell part of the top cover 2 by pressing and fitting, and the valve stem 13 is contracted and slid on the auxiliary pressure piece 8. After the valve stem 13 slides, the return spring 14 is squeezed and elastically deformed; Since the auxiliary pressure member 8 is provided with a liquid supply channel 801 in a circular array with its center as the center of the circle, the valve stem member 13 is arranged in a circular array with the center of the auxiliary pressure member 8 as the center of the circle, and after being arranged, it passes through the liquid supply channel 801, and each valve stem member 13 is arranged in a one-to-one correspondence with each liquid supply channel 801. In addition, since the wide part of the valve stem member 13 is fixedly clamped with the first sealing ring, the second sealing ring and the third sealing ring in sequence from top to bottom, and a connecting hole 1301 is opened between the first sealing ring and the second sealing ring in the valve stem member 13, when the valve stem member 13 is driven to shrink and slide, the connecting hole 1301 is correspondingly connected with the liquid supply channel 801, and the connection between the two is sealed with the assistance of the first sealing ring and the second sealing ring in the valve stem member 13, that is, the corresponding connection between the connecting hole 1301 and the liquid supply channel 801 makes the liquid supply channel 801 arranged in a connected state; Since the longitudinal section of the auxiliary pressure piece 8 is in a "convex"-shaped structure, it is divided into two parts, a narrow part and a wide part, from top to bottom. After being placed, it is movably inserted into the liquid extraction cavity in the main pressure piece 7, and the sleeve part is movably sleeved on the linkage column part in the main pressure piece 7. A sealing ring is fixedly clamped on the outer side of the wide part of the auxiliary pressure piece 8, which fits the liquid extraction cavity in the main pressure piece 7. The sealing ring is used to seal the connection between the wide part of the auxiliary pressure piece 8 and the liquid extraction cavity in the main pressure piece 7. A sealing ring is fixedly clamped at the lower end of the sleeve part of the auxiliary pressure piece 8. The sealing ring fits the linkage column part in the main pressure piece 7. The sealing ring is used to seal the sliding connection between the sleeve part in the auxiliary pressure piece 8 and the linkage column part in the main pressure piece 7. Since a gap for liquid supply is reserved between the narrow part of the auxiliary pressure piece 8 and the wall of the liquid pumping chamber in the main pressure piece 7, and since the liquid supply channel 801 is arranged in an "L"-shaped structure, its upper opening is arranged in an open state, and its upper opening corresponds to the gap between the narrow part of the auxiliary pressure piece 8 and the wall of the liquid pumping chamber in the main pressure piece 7, after the nickel solution enters the liquid pumping chamber in the main pressure piece 7, it fills the gap between the narrow part of the auxiliary pressure piece 8 and the wall of the liquid pumping chamber in the main pressure piece 7. When the valve stem 13 loses its blockage on the liquid supply channel 801, the liquid supply channel 801 remains connected, and the nickel solution enters it through the upper opening of the liquid supply channel 801; Since a plugging column of an integrated structure is vertically downwardly arranged at the center of the pressure liquid chamber in the main pressure member 7, a circulation channel 702 is provided on the plugging column, and the longitudinal section of the circulation channel 702 is arranged in a three-way state, and its ring center coincides with the rotation center of the main pressure member 7, and its upper end is arranged in an open state, and bottom through holes are provided at equal angles on the bottom cavity wall of its lower end, and side through holes are provided at equal angles on the side cavity wall of its middle part, the circulation channel 702 is used for the connection between the pumping cavity and the pressure liquid cavity in the main pressure member 7, and since the lower opening of the liquid supply channel 801 is arranged in an open state, and its lower opening is correspondingly connected to the upper end opening of the circulation channel 702, the nickel solution passes through the lower opening of the liquid supply channel 801, and flows out through the side through holes and the bottom through holes in the circulation channel 702, and flows into the pressure liquid chamber in the main pressure member 7; According to the above, the first electric telescopic rod 10 is started to extend and operate, so that the sleeve part in the auxiliary pressure piece 8 forms a sliding structure downward in the tube shell part in the top cover 2, driving the main pressure piece 7 to move synchronously, and causing the main pressure piece 7 to slide downward in the shell cavity of the filter cartridge shell 1. At this time, the pin part 701 is still in the longitudinal groove path in the "L"-shaped lock groove 101. When the auxiliary pressure piece 8 drives the valve stem 13 to slide downward, the narrow part of the valve stem 13 loses the pressure fit with the lower side wall of the tube shell part in the top cover 2, which is beneficial to the The valve stem 13 is reset by elastic deformation of the reset spring 14, so that the valve stem 13 extends and slides on the auxiliary pressure member 8. After the corresponding connection between the communication hole 1301 and the liquid supply channel 801 is lost, the sealing treatment of the closing part of the two is performed with the assistance of the second sealing ring and the third sealing ring in the valve stem 13, so that the liquid supply channel 801 is set in a closed state. Even if the pressure liquid chamber in the main pressure member 7 is in a closed state, the auxiliary pressure member 8 drives the main pressure member 7 to slide downward, and presses the nickel solution in the pressure liquid chamber of the main pressure member 7; Since the lower port of the filter cartridge shell 1 is in an open state, a sealing ring is fixedly clamped at the connection between the bottom end cover 3 and the filter cartridge shell 1. After the bottom end cover 3 is placed, its upper section is inserted into the lower section shell cavity of the filter cartridge shell 1, and its middle section is clamped at the lower port of the filter cartridge shell 1, and it is sealed and fixed to the lower port of the filter cartridge shell 1 by bolts. In addition, since the cover cavity of the bottom end cover 3 is sequentially provided with an upper chamber and a lower chamber from top to bottom, a through hole is provided at an equal angle on the partition wall between the upper chamber and the lower chamber in the bottom end cover 3, wherein the through hole is used for communication between the upper chamber and the lower chamber, and the nickel solution in the pressure liquid cavity of the main pressure piece 7 is pressed and enters the lower chamber through the through hole between the upper chamber and the lower chamber in the bottom end cover 3; Since the longitudinal section of the lower chamber of the middle chamber of the bottom end cover 3 is in a "convex" shape, which is divided into a wide part and a narrow part, a filter element body 4 is sealed and inserted in the narrow part of the lower chamber of the middle chamber of the bottom end cover 3, and a sealing ring is fixedly clamped on the upper end of the filter element body 4. After placement, the upper end thereof is inserted into the narrow part of the lower chamber of the middle chamber of the bottom end cover 3, and the sealing ring is fixedly inserted on the partition wall between the upper chamber and the lower chamber of the middle chamber of the bottom end cover 3, and the lower end thereof extends to the wide part of the lower chamber of the middle chamber of the bottom end cover 3. Since a gap space for nickel solution to pass is reserved between the filter element body 4 and the narrow part of the wall of the lower chamber of the middle chamber of the bottom end cover 3, after the nickel solution enters the lower chamber of the middle chamber of the bottom end cover 3, it is placed in the gap between the filter element body 4 and the narrow part of the wall of the lower chamber of the middle chamber of the bottom end cover 3, and the nickel solution is filtered through the filter element body 4 by pressing, and then enters the tube cavity of the filter element body 4; Since both upper and lower ends of the assembly seat 15 are fixedly connected with sealing rings, after being installed, the sealing ring is used to assist the sealing plug in the wide part of the lower chamber of the middle cavity of the bottom end cover 3, and the upper sealing ring and the lower sealing ring are used for sealing the connection between the liquid outlet channel 1501 and the liquid outlet pipe in the bottom end cover 3. Since the middle part of the assembly seat 15 is provided with a liquid outlet channel 1501, the liquid outlet channel 1501 is divided into two parts, an upper port and a side port, wherein the upper port is opened in the middle part of the upper wall of the assembly seat 15 in an open state, and wherein the side port is opened in the middle part of the side wall of the assembly seat 15 in an open state, the lower end of the filter element body 4 is fixedly connected with a sealing ring, and after being installed, the lower end thereof is fixedly plugged in the liquid outlet channel 1501 with the sealing ring. The upper port of the channel 1501 is sealed and plugged together, and then the left cover body at the lower end of the bottom cover 3 is provided with an integrated liquid outlet pipe, wherein the liquid outlet pipe is connected to the wide part of the lower chamber of the cavity, and the liquid outlet pipe is sealed and fixedly connected to the nickel plating pool. The nickel plating pool is the prior art and is not described in the drawings of the specification. The side port of the liquid outlet channel 1501 is connected to the liquid outlet pipe in the bottom cover 3, and the filtered nickel solution passes through the liquid outlet channel 1501 and enters the nickel plating pool from the liquid outlet pipe in the bottom cover 3. Based on the above, through the reciprocating telescopic operation of the first electric telescopic rod 10, the reciprocating lifting and sliding of the auxiliary pressure piece 8 and the main pressure piece 7 are controlled to complete the filtration operation of the nickel solution.

When the main pressure piece 7 is driven to completely slide down, the pin column part 701 slides along the longitudinal groove in the "L"-shaped locking groove 101 to the connecting part of the longitudinal groove and the transverse groove; Since the central position of the pumping cavity in the main pressure piece 7 is vertically upwardly provided with an integrated structure of the linkage column, the lower end of the sleeve part in the auxiliary pressure piece 8 is set in an open state, the auxiliary pressure piece 8 is movably inserted into the pumping cavity in the main pressure piece 7 after being placed, wherein the sleeve part is movably sleeved on the linkage column in the main pressure piece 7, and since a spring return piece 9 is provided at the connection between the sleeve part in the auxiliary pressure piece 8 and the linkage column in the main pressure piece 7, the spring return piece 9 is composed of three parts from top to bottom, namely, a connecting disk, a spring body and a connecting ring, wherein the connecting disk The spring return member 9 is fixedly connected to the upper end of the spring body, and the lower end of the spring body is fixedly connected to the connecting ring. After being placed, the spring return member 9 is inserted into the tube cavity of the sleeve part of the auxiliary pressure member 8 in an active state, wherein the connecting plate is inserted and fixedly connected to the upper tube cavity wall of the sleeve part of the auxiliary pressure member 8 by bolts, and wherein the connecting ring is sleeved and fixedly connected to the upper end of the linkage column part of the main pressure member 7 by bolts, and the linkage column part of the main pressure member 7 is rotated in the sleeve part of the auxiliary pressure member 8 by the elastic deformation reset of the spring return member 9 by screwing; Since the main pressure piece 7 is movably inserted into the shell cavity of the filter cartridge shell 1 after being installed, the cavity wall of the pressure liquid cavity is movably inserted into the gap between the bottom end cover 3 and the filter cartridge shell 1, that is, the pressure liquid cavity in the main pressure piece 7 is movably sleeved on the upper section of the bottom end cover 3, and since the arc size of the transverse groove in the "L"-shaped lock groove 101 is ninety degrees, and the arc center of the transverse groove coincides with the rotation center of the main pressure piece 7, after the main pressure piece 7 is driven, a rotating structure is formed in the shell cavity of the filter cartridge shell 1, so that the pin column part 701 slides into the transverse groove in the "L"-shaped lock groove 101, and the transverse groove in the "L"-shaped lock groove 101 is connected with the pin column part 701 in a limiting clamping manner, that is, the main pressure piece 7 is limited; Since the front and rear sides of the linkage column in the main pressure piece 7 are provided with a circular groove 11, the front and rear circular grooves 11 are arranged in opposite directions, and the bolt member 12 is arranged symmetrically front and back about the vertical center axis of the sleeve portion in the auxiliary pressure piece 8. After the bolt member 12 is placed, it is in a vertical state, penetrates through the tube wall of the sleeve portion in the auxiliary pressure piece 8, extends into the tube cavity of the sleeve portion, is fixedly connected to the sleeve portion in the auxiliary pressure piece 8 by bolts, and is movably inserted in the circular groove 11.

The sealing treatment of the connection point 1 makes the bottom through hole in the circulation channel 702 and the connecting port between the upper chamber and the lower chamber of the cavity in the bottom end cover 3 communicate with each other, and makes the upper port of the return flow channel 301 communicate with the side through hole in the circulation channel 702. After the negative pressure vacuum is formed in the liquid extraction cavity in the main pressure piece 7, the nickel solution retained in the narrow part of the lower chamber of the cavity in the bottom end cover 3 is recovered and extracted through the bottom through hole in the circulation channel 702 and the return flow channel 301, and recovered into the liquid extraction cavity in the main pressure piece 7, so as to ensure that the replacement and disassembly of the filter element body 4 is carried out without the accumulation of nickel solution. According to the above, when the unlocking and resetting operation of the main pressure piece 7 is performed, since the head end of the spiral groove 1102 is connected to the tail end of the second vertical groove 1103, and the head end of the first vertical groove 1101 is connected to the tail end of the spiral groove 1102, and since the spiral angle of the spiral groove 1102 is ninety degrees, the first electric telescopic rod 10 is started to continuously contract and operate, so that the auxiliary pressure piece 8 continues to rise and slide in the pumping chamber of the main pressure piece 7, and the spring return piece 9 is pulled to elastically deform. After the auxiliary pressure piece 8 rises and slides in the pumping chamber of the main pressure piece 7, the pin bolt 12 slides from the tail end of the second vertical groove 1103 along the spiral groove 1102 and slides to the head end of the first vertical groove 1101.

When the main pressure piece 7 is reset and rotated, the pin column part 701 slides along the horizontal groove in the "L"-shaped lock groove 101 to the connection between the horizontal groove and the longitudinal groove, and the main pressure piece 7 loses its limit. The spring return piece 9 is used to pull and elastically deform and reset the main pressure piece 7 to reset and slide on the auxiliary pressure piece 8, and the pin bolt 12 is reset and slid along the first vertical groove 1101, and the pin column part 701 is reset and slid along the longitudinal groove of the "L"-shaped lock groove 101, completing the automatic unlocking and resetting of the main pressure piece 7.
