Description

Technical Field

[0001] The present invention belongs to the technical field of plate-and-frame filtration, and relates to a plate-and-frame filtration device and its application in the production of steroid hormones. Background Art

[0002] The plate-and-frame filtration device, also known as a plate-and-frame filter press, is the first mechanical equipment applied to chemical dehydration. Although the plate-and-frame filtration device is generally an intermittent operation and has a large infrastructure investment, due to its advantages such as large filtration driving force, high solid content in the filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs, it is still widely used in some applicable scenarios. For example, in the production processes of steroid drugs such as dihydrodroxy progesterone and progesterone, the plate-and-frame filtration device is used to filter (i.e., pressure filter) the fermented materials after fermentation.

[0003] Currently, the common plate-and-frame filtration devices on the market mainly include a machine frame and a number of filter plates distributed on the machine frame, and filter cloths are provided on both sides of each filter plate; or there are filter plates and filter frames distributed at intervals and crosswise on the machine frame. The surface of the filter plate has grooves, and its protruding parts are used to support the filter cloth. There are through holes at the corners of the filter frame and the filter plate. After assembly, a complete channel is formed, through which suspension, washing water can be introduced, and filtrate can be discharged. There are handles on both sides of the plate and the frame to support on the cross beam, and the plate-and-frame is pressed by a pressing device. The filter cloth between the plate and the frame acts as a sealing gasket. The suspension is pressed into the filter chamber by a feed pump to form filter residue on the filter cloth until the filter chamber is full. The filtrate passes through the filter cloth and flows along the grooves of the filter plate to the corner channels of the plate and the frame, and is discharged centrally. The filtrate passes through the filter cloth and flows along the grooves of the filter plate to the corner channels of the plate and the frame, and is discharged centrally. In either form, both sides of the plate-and-frame (i.e., the filter plate or the filter plate and the filter frame) are lapped on the machine frame through handles. After the pressure filtration (or filtration) is completed, the plate-and-frame is separated one by one through the reciprocating movement of the plate pulling trolley, and at the same time, the filter cake between the plate and the frame falls. However, in actual production, some filter cakes will adhere to the filter cloth, so workers need to manually shovel off the filter cake, or a cylinder is set on the plate pulling trolley to shake the plate-and-frame up and down. The former has low efficiency, and the latter requires additional setting of cylinders, etc., which not only increases the equipment cost, but also needs to consider the layout of air pipes, etc. due to the long length of the machine frame; therefore, the use effect of either method is poor. Summary of the Invention

[0004] The purpose of the present invention is to provide a plate-and-frame filtration device and its application in the production of steroid hormones, aiming to solve the problem of poor use effect.

[0005] To solve the above technical problems, the present invention provides a plate-and-frame filtration device, including:

[0006] A machine frame, the machine frame includes two parallel support beams;

[0007] A plurality of plate frame bodies, with lapping parts arranged on both sides of the plate frame body above the support beam;

[0008] Support rails and a drawbar cart movably located on the support rails. The support rails are horizontally arranged on both outer sides of the frame, and a driving mechanism for driving the drawbar cart to reciprocate is arranged on the frame;

[0009] Lifting members, the lifting members are vertically movably connected to the drawbar cart. A driving arm and a first elastic member for driving the driving arm to reset are vertically hinged on the lifting members. A lifting arm is horizontally movably arranged on the side of the lifting member, and a lifting wheel is vertically rotatably sleeved at the free end of the lifting arm;

[0010] Fixed frames, the fixed frames are horizontally arranged on the outer side of the frame. A plurality of fixed seats are arranged at intervals on the fixed frames. The X side of the fixed seat is an inclined lifting slope, and the -X side is vertical. An obtuse angle is formed between the lifting slope and the top of the fixed frame. When the bottom of the lifting wheel abuts against the top of the fixed seat, the lifting member lifts the lapping part above the support beam, and the driving arm is located on the X side of the corresponding lapping part. When the bottom of the lifting wheel abuts against the fixed frame, the lapping part abuts against the support beam;

[0011] A telescopic mechanism for controlling the lifting arm to move in and out of the lifting member.

[0012] The present invention is further arranged such that the drawbar cart and the lifting member are both in a shape of a cover with an upward opening, and the side of the lifting member is movably attached to the inner wall of the drawbar cart. A hinge column is horizontally arranged on the inner wall of the lifting member. The middle part of the driving arm is hinged to the hinge column. One end of the first elastic member is connected to the inner wall of the lifting member, and the other end is connected to the middle part of the driving arm and is movably sleeved on the hinge column. In the standby state, the bottom of the driving arm abuts against the bottom of the inner wall of the lifting member, and the top is inclined towards the -X direction. When the lifting member moves along the X direction, the lapping part acts on the upper side of the driving arm and causes the driving arm to rotate until the driving arm crosses the lapping part.

[0013] The present invention is further arranged such that an extension cylinder is horizontally arranged on the side of the lifting member. A rectangular parallelepiped-shaped lifting hole is horizontally opened on the extension cylinder and the lifting member. The lifting arm is movably attached to the inner wall of the lifting hole. A cylindrical column part is horizontally arranged at the free end of the lifting arm, and the lifting wheel is rotatably sleeved on the outer wall of the column part. A matching hole for the extension cylinder to move is vertically opened on the drawbar cart, and the top of the matching hole is lower than the top of the drawbar cart.

[0014] The present invention is further configured such that the telescopic mechanism includes a second elastic member that is continuously in a compressed state. Two ends of the second elastic member are respectively fixedly connected to the inner end of the lifting hole and the inner end of the lifting arm. A telescopic wheel is horizontally rotatably provided at the outer end of the cylindrical portion. The top of the fixed seat is a horizontal translation plane, and the outer side of the -X side of the fixed seat is an inclined contraction slope. The inner sides of the fixed frame and the fixed seat are both attached to the outer side of the frame or the support beam. When the telescopic wheel abuts against the outer side of the frame or the support beam, the length of the second elastic member is S1. When the telescopic wheel abuts against the contraction slope, the length of the second elastic member is S2. When the telescopic wheel abuts against the outer side of the fixed seat, the length of the second elastic member is S3, and S3 < S2 < S1.

[0015] The present invention is further configured such that a movable groove is horizontally formed at the bottom of the inner wall of the lifting member. An anti - detachment rod is horizontally provided in the middle of the movable groove. A locking seat is movably provided in the movable groove. The bottom and both sides of the locking seat are movably attached to the inner wall of the movable groove. A third elastic member that is continuously in a compressed state is provided between the -X side of the locking seat and the inner wall of the movable groove. The anti - detachment rod passes through the locking seat, and the outer wall of the anti - detachment rod is attached to the locking seat. A triangular locking groove is formed at the X side of the top of the locking seat;

[0016] An L - shaped locking arm is horizontally provided on the frame. An unlocking seat is provided on the outer side of one of the fixed seats. The locking arm is located on the X side of all the plate - frame bodies, and the unlocking seat is located on the -X side of all the plate - frame bodies. An unlocking opening is horizontally formed at the side of the lifting member. An unlocking arm is horizontally hinged in the unlocking opening. One end of the unlocking arm abuts against the X side of the locking seat, and the other end is located between the lifting member and the fixed frame. The top end of the driving arm includes a driving slope. An opening for the unlocking arm to pass through is formed on the pulling cart;

[0017] The locking seat includes a working state, a locking state, and an unlocking state;

[0018] When the locking seat is in the working state, the driving arm swings reciprocally and moves the plate - frame body, and the locking seat abuts against the X end of the movable groove;

[0019] When the locking seat is in the locked state, the free end of the locking arm abuts against the upper side of the driving arm, the driving inclined surface abuts against the top or the X side of the locking seat in an inclined manner, and drives the locking seat to move in the -X direction relative to the movable slot until the free end of the driving arm is opposite to the locking slot. The locking seat moves in the X direction under the elastic force of the third elastic member, and the free end of the driving arm is clamped through the locking slot, and the driving arm is lower than the overlapping portion;

[0020] When the locking seat is in the unlocked state, the unlocking seat abuts against the -X side of the outer end of the unlocking arm, and the inner end of the unlocking arm abuts against the X side of the locking seat. After the top end of the driving arm disengages from the locking slot, the first elastic member drives the unlocking arm to rotate and reset until the bottom of the unlocking arm abuts against the lifting member.

[0021] The present invention is further configured such that two vertical rods are vertically provided at the bottom of the inner wall of the lifting member. The locking seat is located between the vertical rods and the driving arm. A vertical seat is vertically movably sleeved on the outer walls of the two vertical rods. A bulletproof strip is horizontally provided at the top of the vertical seat. An arc-shaped transition portion is provided at the -X end of the bulletproof strip. The length of the bulletproof strip is greater than the thickness of the plate frame body. The top of the transition portion is connected to the bulletproof strip. A fourth elastic member is provided between the bottom of the vertical seat and the lifting member. A lower pressing plate is horizontally provided on the frame. The bottom of the lower pressing plate is at the same height as or lower than the top of the support beam, and the lower pressing plate is located on the -X side of the unlocking seat;

[0022] When the vertical seat is in the standby state, the bulletproof strip is higher than the bottom of the support beam, and the bottom of the transition portion is lower than the bottom of the support beam.

[0023] The present invention is further configured such that the driving mechanism includes a driving sprocket rotatably provided outside the frame and a motor for driving the driving sprocket. The X ends and -X ends on both sides of the frame are each provided with the driving sprocket. A driving chain is sleeved on the two driving sprockets on the same side. A linkage portion is provided on the pull plate cart, and the linkage portion is connected to the driving chain located above.

[0024] The present invention is further configured such that the longitudinal section of the support rail is rectangular. A socket portion is provided at the bottom of the pull plate cart. The outer wall of the support rail is movably attached to the socket portion, and the linkage portion is connected to the socket portion.

[0025] The present invention also discloses the application of a plate frame filtering device according to any one of the above in the production of steroid hormones.

[0026] Compared with the prior art, the present invention provides a plate and frame filtering device. When filtering, the pulling plate cart is located at the -X end of its maximum stroke. At the same time, the oil cylinder on the frame drives the push plate to move, and the push plate presses all the plate and frame bodies tightly. Then, the material to be filtered is injected into the plate and frame bodies, and the filtrate is discharged after passing through the filter cloth, while the filter residue is filtered out by the filter cloth. After the filtering is completed, the oil cylinder and the push plate are reset (the two have no mutual relationship with the pulling plate cart). Then, the driving mechanism drives the pulling plate cart to move in the X direction. After the first overlapping part touches the driving arm, the driving arm swings until the driving arm crosses the overlapping part, and then it resets under the elastic force of the first elastic member. At this time, the top of the driving arm is higher than the overlapping part. Then, the driving mechanism drives the pulling plate cart to move in the -X direction, thereby driving the plate and frame bodies to move. During this movement, when the bottom of the lifting wheel touches the top of the fixed frame (or slightly higher than the top of the fixed frame), the lifting member is lower than the overlapping part, and the bottom of the driving arm touches the lifting member and cannot rotate. In this way, the plate and frame bodies can be directly driven to translate. When the lifting wheel touches the lifting slope, the height of the lifting wheel is raised, and at the same time, the height of the plate and frame bodies is also increased until the lifting wheel touches the top of the fixed seat. At this time, the overlapping part is higher than the support beam. The lifting member and the lifting wheel continue to move. When the lifting wheel crosses the fixed seat, at this time, under the action of gravity, the plate and frame bodies and the lifting member both drop. Among them, the plate and frame bodies have a large mass, and they will collide with the support beam, so that the filter cake on the filter cloth of the plate and frame bodies can be better shaken off. Moreover, since there are multiple fixed seats on the fixed frame, the plate and frame bodies will vibrate each time to shake off the filter cake, and at the same time, they will also vibrate frequently, which also accelerates the shedding of the filter cake, so that there is no need for workers to manually remove the filter cake, and the use effect is better. Moreover, the frequent vibration can also reduce the residue of the filter residue on the filter cloth, and the removal effect of the filter cake is also better.

[0027] When the first plate and frame body is moved to the designated position, the pulling plate cart moves in the X direction again. Each time the lifting arm passes through the fixed seat, the telescopic mechanism drives the lifting arm to move away from the fixed seat, so that the pulling plate cart can move normally in the X direction until the driving arm crosses the overlapping part of the second plate and frame body, and so on until all the plate and frame bodies are moved.

[0028] It should also be understood that the filtering device of the present application can be used not only in the production of steroid hormones, but also in other scenarios that require pressure filtration, such as sewage treatment, separation of traditional Chinese medicine potions, chemical fields, etc., and no more restrictions are made here.

[0057] The locking seat 26 includes a working state, a locking state, and an unlocking state;

[0058] When the locking seat 26 is in the working state, the driving arm 8 swings reciprocally and moves the plate - frame body 3, and the locking seat 26 abuts against the X end of the movable groove 24;

[0059] When the locking seat 26 is in the locked state, the free end of the locking arm 29 abuts against the upper side of the driving arm 8, the driving inclined surface 33 abuts against the top or the X side of the locking seat 26 in an inclined manner, and drives the locking seat 26 to move in the -X direction relative to the movable slot 24 until the free end of the driving arm 8 is opposite to the locking slot 28.

[0065] The present invention also discloses the application of a plate-frame filter device as described in any one of the above in the production of steroid drugs.

[0066] When the plate-frame filter device provided by the present invention is filtering, at this time, the drawbar truck 6 is located at the -X end of its maximum stroke. At the same time, the oil cylinder on the frame 1 drives the push plate to move, and the push plate presses all the plate-frame bodies 3. Then, the material to be filtered is injected into the plate-frame body 3, and the filtrate is discharged after passing through the filter cloth, while the filter residue is filtered out by the filter cloth. After the filtering is completed, the oil cylinder and the push plate are reset (the two have no mutual relationship with the drawbar truck 6). Then, the driving mechanism drives the drawbar truck 6 to move in the X direction. After the first latching part 4 touches the driving arm 8, the driving arm 8 swings until the driving arm 8 crosses the latching part 4, and then it is reset under the elastic force of the first elastic member 9. At this time, the top end of the driving arm 8 is higher than the latching part 4; then the driving mechanism drives the drawbar truck 6 to move in the -X direction, thereby driving the plate-frame body 3 to move; during this movement process, when the bottom of the lifting wheel 11 touches the top of the fixing frame 12 (or slightly higher than the top of the fixing frame 12), at this time, the lifting member 7 is lower than the latching part 4, and the bottom of the driving arm 8 touches the lifting member 7 and cannot rotate, so that the plate-frame body 3 can be directly driven to translate; when the lifting wheel 11 touches the lifting inclined surface 14, the height of the lifting wheel 11 is raised, and at the same time, the height of the plate-frame body 3 is also increased until the lifting wheel 11 touches the top of the fixing seat 13. At this time, the latching part 4 is higher than the support beam 2; the lifting member 7 and the lifting wheel 11 continue to move. When the lifting wheel 11 crosses the fixing seat 13, at this time, under the action of gravity, the plate-frame body 3 and the lifting member 7 both drop. Among them, the plate-frame body 3 has a large mass and will collide with the support beam 2, so that the filter cake on the filter cloth of the plate-frame body 3 can be better shaken off; not only that, because there are multiple fixing seats 13 on the fixing frame 12, the plate-frame body 3 will vibrate every time to shake off the filter cake, and at the same time, it will also generate frequent jitters, which also accelerates the shedding of the filter cake, so that there is no need for workers to manually remove the filter cake, and the use effect is better; not only that, the frequent jitters can also reduce the residue of the filter residue on the filter cloth, and the removal effect on the filter cake is also better.

[0067] After the first plate frame body 3 is moved to the designated position, the pulling cart 6 moves in the X direction again. Each time the lifting arm 10 passes by the fixed seat 13, the telescopic mechanism drives the lifting arm 10 to move away from the fixed seat 13, so that the pulling cart 6 can move normally in the X direction until the driving arm 8 crosses the overlapping part 4 of the second plate frame body 3. This process is repeated until all the plate frame bodies 3 are moved.

[0068] It should also be understood that the filtration device of the present application can be used in the production of steroid hormones, or in other scenarios that require pressure filtration, such as sewage treatment, separation of traditional Chinese medicine potions, chemical fields, etc., and no further limitations are made here.

[0069] The support beam 2 is preferably cylindrical (or cylindrical or arc-shaped at the top and vertical planar at the bottom, and the planar part is convenient for interacting with the telescopic wheel 21). At the same time, the bottom of the overlapping part 4 has an arc-shaped groove (only for illustration in the figure and does not represent the actual structure). After the grooves at the bottom of the overlapping part 4 are buckled on the support beam 2, all the positions of the plate frame bodies 3 can be made flush; moreover, the plate frame body 3 can be a combination of filter plates and filter cloths, or a combination of filter plates, filter frames and filter cloths. At the same time, there is a horizontal oil cylinder on the frame 1, and a push plate is provided on the output shaft of the oil cylinder, which is used to press all the plate frame bodies 3 against the end of the frame 1. It can be understood that the structures and working principles of the frame 1, the plate frame body 3 (filter plate or filter plate and filter frame), the filter cloth, etc. are the same as those on the market at present, and no further elaboration is made here. The difference from the plate frame filter press on the market lies in parts such as the pulling cart 6, the lifting member 7, the fixed frame 12, etc.; or it can be understood that the present application uses parts such as the pulling cart 6, the lifting member 7, the fixed frame 12, etc. to replace the pulling cart part in the existing plate frame filter press.

[0070] During actual use, after the pressure filtration is completed, the motor drives one or two driving sprockets 40 on the same side to rotate, and then drives the linkage part 42 to move through the driving chain 41. The linkage part 42 drives the pulling cart 6, the lifting member 7, etc. to move in the X direction through the socket part 43; during the movement, when the telescopic wheel 21 abuts against the outside of the frame 1 or the outside of the support beam 2, the lifting arm 10 remains stationary at this time; when the telescopic wheel 21 abuts against the contraction inclined surface 23, under the action of the contraction inclined surface 23, the lifting arm 10 moves into the lifting hole 17 and compresses the second elastic member 20; when the telescopic wheel 21 abuts against the outside of the fixed seat 13, the length of the second elastic member 20 reaches the minimum until the telescopic wheel 21 crosses the fixed seat 13; during this process, the lifting arm 10 only expands and contracts horizontally, so as not to affect the height of the lifting member 7, that is, at this time the driving arm 8 can directly move to cross the corresponding overlapping part 4 (the movement distance of the pulling cart 6 each time is controlled by the servo motor and can accurately act on the corresponding overlapping part 4).

[0071] Then the trolley 6 moves in the -X direction. During the movement, after the top of the lifting member 7 abuts against the bottom of the overlapping portion 4, the overlapping portion 4 is lifted; when the lifting wheel 11 abuts against the translation plane 22, the plate frame body 3 maintains its height at this time. When the lifting wheel 11 moves to the -X end of the fixed seat 13, the plate frame body 3 descends onto the support beam 2 and vibrates.

[0072] If the first plate frame body 3 is driven at this time, before the trolley 6 moves to the mobile game end, the upper side of the transition portion 37 will first act on the X end of the lower pressing plate 39. At this time, the lower pressing plate 39 causes the transition portion 37, the bulletproof strip 36, and the vertical seat 35 to all descend until the bulletproof strip 36 fits against the lower side of the lower pressing plate 39. Then the first plate frame body 3 is driven to the designated position. Then when pulling the second plate frame body 3, during the movement of the trolley 6, the top of the bulletproof strip 36 will abut against the bottom of the overlapping portion 4 or be lower than the bottom of the overlapping portion 4, which can prevent the vertical seat 35 from rising and enable the vertical seat 35, the bulletproof strip 36, and the transition portion 37 to normally cross over the overlapping portion 4 and move to drive the second overlapping portion 4. Among them, as the number of plate frame bodies 3 increases subsequently, the transition portion 37 no longer acts on the lower pressing plate 39, but the overlapping portion 4 that has already moved to the designated position will act on the upper side of the transition portion 37. Similarly, it can also reduce the height of the vertical seat 35 and the bulletproof strip 36, and enable the bulletproof strip 36 to directly cross over all the in-place plate frame bodies 3 when moving in the X direction again without driving the plate frame bodies 3 in the X direction again.

[0073] When all the plate frame bodies 3 are moved to the designated positions, at this time the trolley 6 moves in the X direction to the maximum distance position. During its movement, the free end of the locking arm 29 will abut against the upper side of the driving arm 8 and cause the driving arm 8 to swing; during its swinging process, the driving inclined surface 33 with an inclined top acts on the top or the X side of the locking column, so that the locking seat 26 can move in the -X direction relative to the moving slot 24 and compress the third elastic member 27. Until the free end of the driving arm 8 is aligned with the locking slot 28, at this time the third elastic member 27 drives the locking seat 26 to move in the X direction relative to the moving slot 24 until the top end of the driving arm 8 is caught in the locking slot 28. At this time, the driving arm 8 is lower than all the overlapping portions 4, and the transition portion 37 enables the bulletproof strip 36 and the vertical seat 35 to cross over all the overlapping portions 4. In this way, the driving chain 41 can directly move the trolley 6 and the lifting member 7 in the -X direction; among them, during the movement of the trolley 6 and the lifting member 7 in the -X direction, the oil cylinder and the push plate push all the plate frame bodies 3 in the X direction (either to the maximum distance or a certain distance), and separate the first plate frame body 3 at the -X end from the unlocking seat 30.

[0074] During the movement of the lifting member 7 in the -X direction, the unlocking seat 30 abuts against the -X side of the outer end of the unlocking arm 32, causing the inner end of the unlocking arm 32 to swing towards the -X direction. At the same time, it drives the locking seat 26 to move, causing the free end of the driving arm 8 to disengage from the locking slot 28. Then, the first elastic member 9 (preferably a torsion spring) causes the driving arm 8 to reset until the bottom of the driving arm 8 abuts against the bottom of the inner wall of the lifting member 7.

[0075] If the plate frame body 3 does not need to be cleaned, the oil cylinder and the push plate push all the plate frame bodies 3 in the X direction to the maximum distance; however, if the plate frame body 3 needs to be cleaned, after the push plate pushes all the plate frame bodies 3 a certain distance (not the maximum distance, just leaving a distance for cleaning), the push plate and the oil cylinder reset. Then, the drawbar cart 6 is used again to move each plate frame body 3 in the -X direction one by one. After moving a certain distance, a U-shaped nozzle is used to spray water on both sides of the plate frame body 3. The inner side of the U-shaped nozzle has multiple spray openings and swings or reciprocates during the cleaning process to clean comprehensively. After the cleaning is completed, the plate frame body 3 is vibrated up and down continuously, which can further improve the cleaning effect of the filter cloth.

[0076] In this embodiment, the drawbar cart 6 can not only drive the plate frame body 3 to move, but also naturally generate frequent vibrations during the movement, making the detachment effect of the filter cake better and the cleaning effect of the residues after cleaning better. Secondly, when all the plate frame bodies 3 are moved to the -X end, the driving arm 8 of the drawbar cart 6 can be automatically retracted into the lifting member 7 during the reset process, without the need for workers to manually fix the angle of the driving arm 8. Similarly, the unlocking of the driving arm 8 is also automatic, and the overall use effect is better.

[0077] In yet another embodiment, there are lifting arms 10 on both sides of the lifting member 7. According to the actual situation, there can be a plurality of lifting arms 10 on both sides, which can further improve the vertical movement stability of the lifting member 7 and also extend the service life of the drawbar cart 6 part. The inner telescopic wheel 21 abuts against the frame 1 or the support beam 2, while the outer telescopic wheel 21 can abut against a specially provided steel plate (a part of the frame 1). There are also a fixing frame 12 and a fixing seat 13 on the inner side of the steel plate.

[0078] It should also be supplemented and explained that all "settings" and similar descriptive words in this application (especially in the specification) express that there is a connection relationship between two structures, but there is no excessive limitation on the specific means by which the two are connected, and it is usually a conventional connection means, that is, it should be understood that this means is the prior art and does not need to be elaborated too much. For example, "n is provided on m" only expresses that there is an n structure on the m structure, and whether the two are connected by welding, riveting, adhesive bonding or integrally formed is within the protection scope of this application; another example is "y is rotatably provided on x", which only expresses that y and x can rotate relative to each other, and as for whether the two are rotationally connected by a bearing, or y directly passes through x and is rotationally connected to x, or other achievable ways, they are all within the protection scope of this application.

[0079] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure are within the protection scope of the claims.
