[0003] In the prior art, a Chinese patent with announcement number CN220142747U discloses a melting and filtering device for high-temperature molten salt processing, including a working cylinder, a filter cylinder is fixedly connected to the inner upper end face of the working cylinder, a feed cylinder is fixedly connected to the center of the upper end face of the filter cylinder, a rotating shaft is rotatably connected between the front and rear inner walls of both sides of the filter cylinder, a crushing roller is fixedly sleeved on the outer walls of the two rotating shafts, a plurality of filter holes are opened on the lower end face of the filter cylinder, and a fixing ring is fixedly connected to the middle of the inner walls of both sides of the working cylinder. The patent can achieve better processing purposes during melting by setting up filtering and preheating functions, thereby achieving better use purposes, and the function of cleaning the inner wall can achieve better processing of salts remaining on the inner wall, thereby achieving better cleaning effects and having better practicality.

[0004] In the above technical solution, filtering is performed through the filter cartridge that is set up, and the filter cartridge can intercept impurities in the molten salt. However, the impurities after interception will remain in the inside of the filter cartridge.

In the process of continuing to filter the molten salt, it is easy to cause the molten salt to accumulate above the filter cartridge, thereby resulting in a decrease in the filtration speed, thereby increasing the possibility of waste caused by molten salt solidification.

[0027] like Figure 5 and Figure 6 As shown, the material receiving unit includes a driving pinion 16 rotatably connected to the inner wall of the box body 1, and the driving pinion 16 is meshed with the driving gear 15. By setting the meshing of the driving gear 15 and the driving pinion 16, through the transmission ratio of the gears, it can be known that the movement process of the driving pinion 16 is faster, thereby adapting to the movement of the transverse rack 17 and the transverse rack 24.

A dovetail groove 28 is opened on one side of the inclined base plate 8, and two dovetail blocks 29 are slidably connected to the inner wall of the dovetail groove 28.

Through the design of the dovetail groove 28 and the dovetail block 29, the collecting box 9 can be taken out, so as to process the impurities. One side of the box body 1 is fixedly connected with a discharge pipe 5.

[0030] The specific working method is: when in use, firstly, the molten salt fluid is passed through the feed pipe 4 into the filter cartridge 3 for filtration. During the filtration process, the impact of the molten salt entering can drive the blades 44 to rotate, so that the cavity seat 43 drives the brush plate 55 to rotate to remove impurities at the liquid inlet above the filter screen, thereby avoiding the accumulation of impurities and accelerating clogging; During the filtering process, when too many impurities accumulate above the metal filter 36 and cause blockage, the flow rate of the molten salt discharge will decrease. The flow sensor 7 detects the change in flow rate and can transmit a signal to the controller. The controller controls the motor 13 to drive the driving gear 15 to rotate, thereby driving the driving rack 18 to descend. The driving rack 18 drives the driving rack 2 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 rotation of the valve core plate 21. The valve core plate 21 rotates ninety degrees to realize the feed pipe 4 interruption processing. By timely interruption, it is possible to avoid continuing to feed when blocked, so as to avoid increasing the waste of molten salt. In the process of cutting the material, the driving gear 15 drives the rotation of the driving gear 16, and then drives the movement of the transverse rack 17. The movement of the transverse rack 17 can drive the ring 27 and the flap 35 on the ring 27 that is rotatably connected by the coil spring shaft 34 to move synchronously through the connecting rod 26. When the flap 35 touches the edge of the annular gap formed between the filter cylinder 3 and the funnel 6 during the movement, 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 to form a complete material receiving box, which can realize the receiving of the cleaned impurities. When the circular ring 27 enters the annular gap, the electromagnetic valve 33 is in the open state, and the right-angle piston rod 23 can slide inside the sealing cylinder 31, so that the transverse rack 24 is not moved by force. After the circular ring 27 enters the annular gap, the electromagnetic valve 33 is closed. At this time, the transverse rack 17 is disengaged from the driving pinion 16, and the transverse rack 17 continues to move through the right-angle piston rod 23 to drive the sealing cylinder 31 together with the transverse rack 24 to move, thereby realizing the rotation of the flipping gear 25, and then driving the rotation of the two rotating rods 23 to realize the flipping of the metal filter 36. During the rotation of one of the rotating rods 23, the notched gear 1 38 can be synchronously driven to rotate, thereby realizing the descending of the vibration rack 1 39, and then driving the descending of the vibration spherical rod 45, so as to achieve its avoidance when the metal filter 36 is flipped; After the metal filter 36 is flipped, the notched gear 38 is disengaged from the vibration rack 39, and the vibration rack 39 drives the vibration spherical rod 45 to reset through the reset spring 40, so as to knock the end of the cavity seat 43. After the flipping is completed, the convex ball slide plate 46 will automatically fall and engage with the slot 57 opened at the bottom of the cylinder 42. At this time, the cylinder 42 can be limited, so that when the cavity seat 43 is knocked, the cavity seat 43 rotates under the action of the T-shaped plate 48 and the limit pin 49 in the arc guide groove 50, thereby driving the rotation of the brush plate 55. The brush plate 55 will produce a certain centrifugal effect during the rotation process, and the brush plate 55 can slide inside the rectangular cavity 52 under the action of the rectangular cavity 52 and the tension spring 53, thereby improving the cleaning effect of the metal filter 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 cleaning comb plate 56, thereby further improving the cleaning effect.

[0031] After the cleaning is completed, the motor 13 reverses. At this time, under the action of the one-way bearing 62, the notched gear 1 38 and the rotating rod 2 37 rotate relative to each other. The rotating rod 2 37 drives the notched gear 2 61 to rotate, thereby driving the vibration rack 2 60 to descend, and then driving the pressure rod 63 to descend to press down the vibration spherical rod 45, thereby avoiding the reset of the metal filter 36. At the same time, the ring 27 and the flap 35 move out of the annular notch, and the flap 35 rotates to pour the collected impurities into the collection box 9 to realize the collection of impurities. At this point, the cleaning work is completed.
