Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a plate-frame filter for separating Angelica dahurica polysaccharides. Background Art

[0002] In the process of Angelica dahurica polysaccharide production and extraction, the solution after crude extraction often contains some insoluble impurities, such as plant fibers, cell wall fragments, etc. The plate and frame filter can be used as a preliminary pretreatment equipment to quickly and effectively remove these larger particle impurities, making the subsequent refining steps smoother. For example, after Angelica dahurica is extracted with water or alcohol, there may be a large amount of insoluble residue in the obtained extract. These residues can be removed by plate and frame filtration to obtain a relatively clear solution containing Angelica dahurica polysaccharide. The plate and frame filter is mainly composed of a plurality of filter plates and filter frames arranged alternately. There are grooves on the surface of the filter plates and filter frames, and channels for filtrate and filter residue are formed during assembly. When used to separate Angelica dahurica polysaccharide, the solution containing Angelica dahurica polysaccharide is pumped into the plate and frame filter through the feed port. Under the action of pressure, the solution passes through the filter cloth, and the polysaccharide solution passes through the filter cloth as the filtrate into the filtrate channel, while the impurities, macromolecular substances, etc. in the solution are retained on the filter cloth to form filter residue.

[0003] Existing publication number CN221752425U discloses a plate-and-frame filter comprising a work frame, a support frame fixed to the top of the work frame, and a plurality of self-locking universal wheels fixed to the bottom of the work frame. A water pan is placed on the upper end of the work frame. A plate-and-frame filter assembly is provided on one side of the work frame. The upper end of the plate-and-frame filter assembly is connected to a liquid outlet, and the lower end of the plate-and-frame filter assembly is connected to a liquid inlet. The liquid inlet is connected to a booster pump via a delivery pipe. An exhaust valve is provided on the upper end of the plate-and-frame filter assembly. A pressure plate is movably connected to the other side of the work frame. The pressure plate is driven to adjust its position by a threaded rod and a handle. A movable assembly is provided on the upper end of the support frame, and the movable assembly drives the cleaning assembly to adjust its position. This plate-and-frame filter uses a multi-section electric push rod to drive a spray head to adjust the spray angle, flushing the filter surface between the two filter plates. This solves the problem of inconvenient cleaning of the filter plates and makes cleaning more time-saving and labor-saving.

[0004] However, when removing the plate frame of the existing plate-and-frame filter, it is necessary to first loosen the pressing device and then remove the plate frames in sequence. When the plate frame in the middle position is damaged during use of the plate-and-frame filter, for example, the filter screen is damaged, the plate frame needs to be repaired or replaced. When removing the plate frame, the outer plate frames also need to be removed in sequence, which makes the process of replacing the plate frame in the middle position cumbersome and inconvenient.

DETAILED DESCRIPTION

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 8 , the utility model provides a technical solution.

[0027] A plate-and-frame filter for separating angelica polysaccharides, comprising a support platform 1 and a plurality of plate frames 6, wherein a support plate 2 is fixedly connected to the top of the support platform 1, two symmetrically arranged second side rails 18 are fixedly connected to the right surface of the support plate 2, the plate frame 6 is located between the two second side rails 18, the opposite surfaces of the two second side rails 18 are connected to a horizontally movable support slide 13, the opposite surfaces of the two support slide rails 13 are connected to a horizontally movable first side rail 16, each plate frame 6 is fixedly connected to a support arm 7 on both sides, a sliding sleeve 9 is movably sleeved on the surface of each support arm 7, and the bottom end of each sliding sleeve 9 is connected to a docking slider 10 that can be snapped between the first side rail 16 and the second side rail 18;

[0028] By providing the docking slider 10, the supporting slide rail 13, the first side rail 16 and the second side rail 18, the distance between the first side rail 16 and the second side rail 18 is shortened or extended by horizontally moving the first side rail 16 and the supporting slide rail 13. When the docking slider 10 is located between the first side rail 16 and the second side rail 18, the distance between the first side rail 16 and the second side rail 18 is shortened, and the docking slider 10 can be engaged, so that the plate frame 6 is placed on the first side rail 16 and the second side rail 18. When the distance between the first side rail 16 and the second side rail 18 is extended, the engagement of the docking slider 10 can be released. At this time, the plate frame 6 can be moved upward and removed from the filter, which is beneficial for directly removing the plate frame 6 that needs to be replaced or modified without moving other plate frames 6, thereby facilitating maintenance.

[0029] The bottom surface of each docking slider 10 is fixedly connected to a connecting block 11, and the top of each supporting slide rail 13 is cooperated with a docking slide 12 for the connecting block 11 to be embedded. Both sides of each docking slider 10 are fixedly connected to a clamping block 21, and the side opposite to each first side rail 16 and the second side rail 18 is cooperated with a clamping slide 17 for the clamping block 21 to be clamped. The clamping block 21 is clamped into the clamping slide 17, so that the plate frame 6 cannot separate from the first side rail 16 and the second side rail 18. Both sides of each supporting slide rail 13 are fixedly connected to a T-shaped slider 14, and the side opposite to each first side rail 16 and the second side rail 18 is cooperated with a T-shaped slide groove 15 for the T-shaped slider 14 to slide horizontally. The length of the T-shaped slider 14 is greater than the length of the clamping block 21, ensuring that the sliding distance of the T-shaped slider 14 in the T-shaped slide groove 15 can make the clamping block 21 have been moved out of the clamping slide 17.

[0030] A spring 8 is fixedly connected between the support arm 7 and the sliding sleeve 9. When the first side rail 16 and the second side rail 18 are pulled close to the engaging and docking slider 10, the support arm 7 will retract into the sliding sleeve 9, and the spring 8 will be compressed to store elastic potential energy. When the first side rail 16 and the second side rail 18 are pulled away from the engaging and docking slider 10, the support arm 7 will extend outward from the sliding sleeve 9. At this time, the elastic potential energy of the spring 8 will be released, and the plate frame 6 can be moved upward and removed from the filter. The spring 8 is used to ensure that the support arm 7 remains extended from the sliding sleeve 9 after the plate frame 6 is removed, so that when the plate frame 6 is installed later, the connecting block 11 at the lower end of the docking slider 10 can be embedded in the docking slide 12 by moving it from top to bottom.

[0031] The same end of the two first side rails 16 is fixedly connected to a control block 19, and the surface of the support plate 2 is provided with a limiting slide 20 for horizontal movement of the control block 19. Two motors 22 are fixedly installed on the surface of the support plate 2. The output ends of the two motors 22 are coaxially fixedly connected to a threaded rod 23. The surfaces of the two control blocks 19 are provided with threaded holes 24 for threaded connection of the threaded rod 23. The two motors 22 respectively control the rotation of the two threaded rods 23, thereby respectively controlling the horizontal movement of the two control blocks 19 along the track of the limiting slide 20.

[0032] Two reinforcing rods 25 are movably inserted at the top of the support plate 2, and the tops of the two control blocks 19 are both provided with reinforcing grooves 27 for the reinforcing rods 25 to be embedded. The surface of the support plate 2 is provided with auxiliary grooves 26 for the reinforcing rods 25 to be embedded. The auxiliary grooves 26 are not connected to the limiting slide grooves 20. By setting the reinforcing rods 25 to be embedded in the reinforcing grooves 27, the horizontal movement of the control blocks 19 is limited, which is beneficial to prevent the control blocks 19 from sliding when the filter is working. By setting the auxiliary grooves 26, when the reinforcing rods 25 are moved out of the reinforcing grooves 27, they can be embedded in the auxiliary grooves 26 to prevent the control blocks 19 from being unable to move back to their original positions if the reinforcement rods 25 are left alone.

[0033] The surface of the support plate 2 is fixedly connected with a support rod 3, the bottom end of each plate frame 6 is fixedly connected with a foot block 5, and the bottom end of each foot block 5 is provided with a lap groove 4 for the support rod 3 to overlap.

[0034] The specific solution is as follows: when it is necessary to disassemble one of the plate frames 6, first pull out the reinforcement rod 25 from the reinforcement groove 27, and then start the motor 22 to drive the threaded rod 23 to rotate. Due to the action of the thread, the threaded rod 23 rotates to make the control block 19 move along the track of the limiting slide groove 20. The control block 19 moves and drives the first side rail 16 to move. When the first side rail 16 moves to the maximum limit, it will drive the supporting slide rail 13 to move. The movement of the supporting slide rail 13 will drive the docking slider 10 to move. The movement of the docking slider 10 will drive the sliding sleeve 9 to move. The movement of the sliding sleeve 9 will release the elastic potential energy of the spring 8 until the supporting slide rail 13 moves to the maximum limit. At this time, the two clamping blocks 21 have been moved out of the two clamping slides 17 respectively, and the elastic potential energy of the spring 8 has been released. At this time, any plate frame 6 can be removed upward.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
