Description

Technical Field

[0001] The present invention relates to the technical field of molten salt processing, and in particular to a melting and filtering device for high-temperature molten salt processing. Background Art

[0002] Melting and filtering devices for high-temperature molten salt processing are widely used in industry. These applications have relatively high requirements for the purity and stability of molten salt, so melting and filtering devices are needed to ensure the quality of molten salt.

[0003] In the prior art, a Chinese patent with the publication number CN220142747U discloses a melting and filtering device for high-temperature molten salt processing, including a working cylinder. The upper end face inside the working cylinder is fixedly connected with a filtering cylinder. The center of the upper end face of the filtering cylinder is fixedly connected with a feeding cylinder. Between the front and rear positions on both inner walls of the filtering cylinder, rotating shafts are rotatably connected. Fixed crushing rollers are fixedly sleeved on the outer walls of the two rotating shafts. A plurality of filtering holes are opened on the lower end face of the filtering cylinder. Fixed rings are fixedly connected to the middle positions on both inner walls of the working cylinder. This patent can achieve better processing purposes during melting through the functions of filtering and preheating, so as to achieve better usage purposes. At the same time, the function of cleaning the inner wall can achieve better treatment of the residual salt on the inner wall, so as to achieve better cleaning effects and has better practicability.

[0004] In the above technical solution, filtering is carried out through the provided filtering cylinder. The filtering cylinder can intercept impurities in the molten salt. However, the intercepted impurities will remain inside the filtering cylinder. After long-term use, impurities inside the filtering cylinder will accumulate. If not cleaned in time, it will cause blockage. Moreover, the filtering cylinder in the above technical solution is fixedly arranged inside the working cylinder, so it is not convenient to clean it in time after blockage. During the process of continuously filtering molten salt, it is easy to cause molten salt to accumulate above the filter cylinder, resulting in a reduction in the filtering speed, and thus increasing the possibility of waste caused by the solidification of molten salt.

[0019] Compared with the prior art, the significant advantages of the present invention are as follows:

[0020] Firstly: When the cleaning component provided in the present invention is blocked, a signal is sent by the flow sensor, and the controller controls the start of the motor, enabling automatic material cut-off and cleaning of impurities on the metal filter screen. Thus, when the metal filter screen is blocked, the automatic cleaning function is realized, avoiding the problem that when the filter is blocked and not cleaned in time, molten salt accumulates above the filter cartridge during continuous filtration of molten salt, resulting in a decrease in the filtration speed and an increased possibility of waste caused by solidification of molten salt;

[0021] Secondly: When the first notched gear rotates away from the first vibrating rack, the first vibrating rack can drive the vibrating spherical rod to reset through the return spring, thereby knocking on the end of the cavity seat. After the flipping is completed, the convex ball slide plate will automatically fall and engage with the card slot opened at the bottom of the cylinder. At this time, the cylinder can be limited, so that when the cavity seat is knocked, the cavity seat rotates due to the T-shaped plate and the limit pin under the action of the arc-shaped guide groove, thereby driving the rotation of the brush plate. During the rotation of the brush plate, a certain centrifugal effect will be generated, and the brush plate can slide inside the rectangular cavity through the action of the rectangular cavity and the tension spring, improving the cleaning effect of the metal filter screen. At the same time, the brush plate sliding inside the rectangular cavity can automatically clean the bristles on the brush plate through the provided cleaning comb teeth plate, further improving the cleaning effect;

[0022] Thirdly: The right-angled piston rod drives the sealing cylinder and the second transverse rack to move synchronously, realizing the rotation of the flipping gear, and then driving the rotation of the two second rotating rods, realizing the flipping of the metal filter screen. The connecting rod drives the synchronous movement of the ring and the flap rotatably connected to the ring through the torsion spring shaft. During the movement of the flap, when it touches the edge of the annular gap formed between the filter cylinder and the funnel, the edge squeezes the flap, and the flap rotates until the ring coincides with the formed annular gap, and the flap is parallel to the ring, forming a complete material receiving box, which can realize the material receiving of the impurities falling after the flipping of the metal filter screen, improving the cleaning effect of the filter screen.

[0023] It solves the problem that the existing filter cartridge is not easy to clean in time after being blocked, and during the continuous filtration of molten salt, molten salt accumulates above the filter cartridge, resulting in a decrease in the filtration speed and an increased possibility of waste caused by solidification of molten salt.

One end of the rotating shaft penetrates the surface of the feed pipe 4 and is fixedly connected to the surface of the valve core plate 21. A control gear 20 is fixedly connected to the surface of the rotating shaft. The control gear 20 meshes with the driving rack 2 19. The connection between the rotating shaft and the valve core plate 21 can drive the valve core plate 21 to rotate;

[0044] The auxiliary cleaning unit includes a metal filter screen 36 rotatably arranged on the inner wall of the filter cylinder 3.

[0045] As Figure 2 and Figure 4 As shown, the automatic material cutting unit further includes a rotating rod 14 rotatably connected to the inner wall of the box body 1. A driving large gear 15 is fixedly connected to the surface of the rotating rod 14. A rectangular cylinder 10 is fixedly connected to the inner bottom wall of the box body 1. A driving rack 18 is slidably connected to the inner wall of the rectangular cylinder 10. The rectangular cylinder 10 can limit the movement of the driving rack 18. The driving large gear 15 meshes with the driving rack 18. A funnel 6 fixedly connected to the surface of the filter cylinder 3 through a U-shaped rod. There is a gap between the funnel 6 and the filter cylinder 3 to allow the ring 27 and the flap 35 to enter. The connection between the funnel 6 and the filter cylinder 3 through the U-shaped rod can be referred to in Appendix Figure 2 and 5 It can be obtained that a flow sensor 7 is fixedly installed on the surface of the funnel 6. The flow sensor 7 is electrically connected to a controller. The flow sensor 7 is a prior art and will not be described in detail here. A motor 13 is fixedly installed on the inner wall of the box body 1 through a cross plate. The output end of the motor 13 is fixedly connected to one end of the rotating rod 14.

[0046] As Figure 9 and Figure 10As shown, the cleaning unit includes a plurality of rectangular holes opened on the surface of the cavity seat 43. The inner walls of the plurality of rectangular holes are fixedly connected with rectangular cavities 52. The inner walls of the plurality of rectangular cavities 52 are fixedly connected with tension springs 53. The inner walls of the plurality of rectangular cavities 52 are slidably connected with brush plates 55. The bottom of the brush plates 55 is provided with bristles. The bristles can be made of soft materials, which can prevent impurities from being rigidly squeezed into the filter holes. One sides of the plurality of brush plates 55 are respectively fixedly connected with one ends of the corresponding plurality of tension springs 53. The surfaces of the plurality of rectangular cavities 52 are fixedly connected with fixing rods 54. One ends of the plurality of fixing rods 54 are fixedly connected with cleaning comb plates 56. The cleaning comb plates 56 are perpendicular to the bristles. When the brush plates 55 are affected by the centrifugal force change and then reciprocate, the horizontal cleaning comb plates 56 can clean the bristles, further improving the cleaning effect of the brush plates 55. An arc-shaped guide groove 50 is opened on the surface of the cylinder 42. The guiding angle of the arc-shaped guide groove 50 is 90 degrees, which can adapt to four cleaning units, thereby improving the cleaning effect.

[0047] As Figure 10 and Figure 11 shown, the limiting unit includes a convex spherical slide plate 46 slidably arranged on the inner wall of the circular groove. Two limiting grooves 47 are opened on the inner wall of the circular groove. The inner walls of the two limiting grooves 47 are respectively slidably connected with the surface of the convex spherical slide plate 46. A plurality of clamping grooves 57 are opened on the inner bottom wall of the cylinder 42. By setting the convex spherical slide plate 46 and the clamping grooves 57, the cylinder 42 can be limited after the metal filter screen 36 is flipped. There can be a certain coincidence error between the convex spherical slide plate 46 and the clamping grooves 57. When the cavity seat 43 is driven by a knock to slightly rotate the cylinder 42, the convex spherical slide plate 46 and the clamping grooves 57 can be made to coincide and match, thus forming a clamped state. Therefore, even if the initial positions of the clamping grooves 57 and the convex spherical slide plate 46 do not match, it will not affect the final clamping effect.

[0048] As Figure 8 and Figure 9As shown in the figure, the flipping and vibrating cleaning unit includes two second rotating rods 37 rotatably connected to the inner wall of the filter cylinder 3. The opposite surfaces of the two second rotating rods 37 are fixedly connected to the same metal filter screen 36. The surface of one of the second rotating rods 37 is fixedly connected to a flipping gear 25. The surface of one of the second rotating rods 37 is fixedly connected to two one-way bearings 62. The moving directions of the two one-way bearings 62 are opposite. The one-way bearing 62 belongs to the prior art. The one-way bearing 62, also known as an overrunning clutch, is a special type of bearing. Its characteristic is that it can rotate freely in one direction and lock in the other direction. The surfaces of the two one-way bearings 62 are respectively fixedly connected to a notched gear one 38 and a notched gear two 61.

The bottom ends of the two reset springs 40 are respectively fixedly connected to a vibrating rack one 39 and a vibrating rack two 60. The inner wall of the filter cylinder 3 is provided with two rectangular grooves 58. The inner walls of the two rectangular grooves 58 are slidably connected to rectangular blocks 59. By providing the rectangular grooves 58 and the rectangular blocks 59, the limits of the vibrating rack one 39 and the vibrating rack two 60 can be realized. One sides of the two rectangular blocks 59 are respectively fixedly connected to one sides of the vibrating rack one 39 and the vibrating rack two 60. The vibrating rack one 39 meshes with the notched gear one 38, and the vibrating rack two 60 meshes with the notched gear two 61. The inner top wall of the vibrating rack one 39 is fixedly connected to a spring 64. The bottom end of the spring 64 is fixedly connected to a vibrating spherical rod 45. The bottom end of the vibrating rack two 60 is fixedly connected to a pressing rod 63. The pressing rod 63 can drive the vibrating spherical rod 45 to descend.

[0049] The inner wall of the box body 1 is respectively provided with a first chute 11 and a second chute 12. The inner wall of the second chute 12 is slidably connected to a second horizontal rack 24. The second horizontal rack 24 meshes with the flipping gear 25. Both sides of the second horizontal rack 24 are fixedly connected to a limiting rod 30. One ends of the two limiting rods 30 are fixedly connected to the same sealing cylinder 31. The inner wall of the sealing cylinder 31 is slidably connected to a right-angled piston rod 23. One end of the sealing cylinder 31 is fixedly communicated with an air pipe 32. The surface of the air pipe 32 is fixedly installed with an electromagnetic valve 33. The electromagnetic valve 33 belongs to the prior art. The inner wall of the box body 1 is provided with a material receiving unit.

[0050] As Figure 5 and Figure 6 shown in the figure, the material receiving unit includes a driving pinion 16 rotatably connected to the inner wall of the box body 1. The driving pinion 16 meshes with a driving gear 15. By setting the meshing of the driving gear 15 and the driving pinion 16, through the gear transmission ratio, it can be known that the movement process of the driving pinion 16 is faster, so as to adapt to the movement of the first horizontal rack 17 and the second horizontal rack 24. The inner wall of the first chute 11 is slidably connected to a first horizontal rack 17. The first horizontal rack 17 meshes with the driving pinion 16. The upper surface of the first horizontal rack 17 is fixedly connected to a connecting rod 26.

[0051] One end of the connecting rod 26 is fixedly connected with a ring 27. The surface of the ring 27 is provided with a torsion spring shaft 34 through a connecting seat. The surface of the torsion spring shaft 34 is fixedly connected with a rotating seat. The surface of the rotating seat is fixedly connected with a flap 35. By setting the torsion spring shaft 34, the flap 35 can be reset. The torsion spring shaft 34 is a prior art.

[0052] The inner bottom wall of the box body 1 is fixedly connected with an inclined base plate 8. The inclined base plate 8 can timely discharge the filtered molten salt. One side of the inclined base plate 8 is provided with a dovetail groove 28. Two dovetail blocks 29 are slidably connected to the inner wall of the dovetail groove 28. The same collecting box 9 is fixedly connected to one side of the two dovetail blocks 29. Through the design of the dovetail groove 28 and the dovetail blocks 29, the collecting box 9 can be taken out, so as to process impurities. One side of the box body 1 is fixedly communicated with a discharge pipe 5.

[0053] The specific working method is as follows: When in use, first, the molten salt fluid is introduced into the filter cylinder 3 through the feed pipe 4 for filtration. During the filtration process, the impact of the molten salt entering can drive the rotation of the blade 44, so that the cavity seat 43 drives the brush plate 55 to rotate, and the impurities at the liquid inlet above the filter screen can be swept away, avoiding the accumulation of impurities and accelerating the blockage.

[0054] During the filtration process, when the impurities accumulated above the metal filter screen 36 are too many and cause blockage, at this time, the flow rate of the molten salt feeding will decrease. The flow sensor 7 detects the change in the flow rate and can transmit the signal to the controller. The controller controls the motor 13 to drive, so as to drive the driving large gear 15 to rotate, and then drive the driving rack one 18 to descend. The driving rack one 18 drives the driving rack two 19 to descend, which can drive the control gear 20 to rotate. The rotation of the control gear 20 can drive the rotating shaft to drive the valve core plate 21 to rotate. When the valve core plate 21 rotates 90 degrees, the feeding of the feed pipe 4 can be cut off. By cutting off the feed in time, it can be avoided to continue feeding when blocked, so as to avoid increasing the waste of molten salt.

[0055] During the process of cutting off the feed, the driving large gear 15 drives the driving small gear 16 to rotate, and then drives the horizontal rack one 17 to move. The movement of the horizontal rack one 17 can drive the ring 27 and the flap 35 rotatably connected to the ring 27 through the torsion spring shaft 34 to move synchronously through the connecting rod 26. During the movement of the flap 35, when it touches the edge of the annular gap formed between the filter cylinder 3 and the funnel 6, the edge squeezes the flap 35, and the flap 35 rotates until the ring 27 coincides with the formed annular gap, and the flap 35 is parallel to the ring 27, forming a complete material receiving box, which can realize the receiving of the cleaned impurities.

[0056] During the process of the ring 27 entering the annular vacancy, the solenoid valve 33 is in the open state. The right-angle piston rod 23 can slide inside the sealing cylinder 31. Therefore, the transverse rack two 24 does not move under force. After the ring 27 enters the annular vacancy, the solenoid valve 33 closes. At this time, the transverse rack one 17 continues to move, driving the sealing cylinder 31 together with the transverse rack two 24 through the right-angle piston rod 23, realizing the rotation of the reversing gear 25, and then driving the rotation of the two second rotating rods 37, realizing the turning of the metal filter screen 36. During the rotation of one of the second rotating rods 37, it can synchronously drive the rotation of the notch gear one 38, thereby realizing the descent of the vibration rack one 39, and then driving the descent of the vibration spherical rod 45, so as to realize its avoidance during the turning of the metal filter screen 36;

[0057] After the turning of the metal filter screen 36 is completed, the notch gear one 38 is disengaged from the vibration rack one 39. The vibration rack one 39 drives the vibration spherical rod 45 to be reset through the return spring 40, and can strike the end of the cavity seat 43. After the turning is completed, the convex ball slide plate 46 will automatically fall to engage with the card slot 57 opened at the bottom of the cylinder 42. At this time, the limit of the cylinder 42 can be realized, so that when the cavity seat 43 is struck, the cavity seat 43 rotates under the action of the T-shaped plate 48 and the limit pin 49 in the arc-shaped guide groove 50, and then drives the rotation of the brush plate 55. The brush plate 55 will generate a certain centrifugal effect during rotation, and can realize the sliding of the brush plate 55 inside the rectangular cavity 52 through the action of the rectangular cavity 52 and the tension spring 53, improving the cleaning effect on the metal filter screen 36. At the same time, the brush plate 55 sliding inside the rectangular cavity 52 can automatically clean the bristles on the brush plate 55 through the arranged cleaning comb tooth plate 56, further improving the cleaning effect.

[0058] After the cleaning is completed, the motor 13 rotates in reverse. At this time, under the action of the one-way bearing 62, relative rotation occurs between the notch gear one 38 and the second rotating rod 37. The second rotating rod 37 drives the notch gear two 61 to rotate, and then drives the vibration rack two 60 to descend, and then drives the pressure rod 63 to descend to press down the vibration spherical rod 45, so as to make way for the reset of the metal filter screen 36. During the reset, the ring 27 and the flap 35 are removed from the annular notch, and the flap 35 rotates to pour the collected impurities into the collection box 9, realizing the collection of impurities. So far, the cleaning work is completed.
