Description

Technical Field

[0001] The utility model belongs to the field of water filtering, and more specifically, relates to a water pipe filtering device for a continuous casting crystallizer. The utility model also relates to a continuous casting crystallizer. Background Art

[0002] The continuous casting crystallizer is a trough-shaped container with a jacket on the wall or a coil inside the container to heat or cool the solution in the trough. Most of the existing continuous casting crystallizers are connected to water supply and drainage pipelines to cool the trough container. Generally speaking, in order to prevent the pipeline from being blocked, a filter needs to be installed in the pipeline. The existing filters are usually installed in various valve bodies of the pipeline (such as pressure reducing valves, pressure relief valves and water level valves). Structurally, the filter consists of a cylinder, a stainless steel filter screen, a sewage discharge part, a transmission device and an electrical control part.

[0003] When the filter is working, the water to be filtered enters from the water inlet, flows through the filter, and enters the pipe required by the user through the outlet for process circulation. The particulate impurities in the water are trapped inside the filter. In this continuous cycle, more and more particles are trapped, and the filtration speed becomes slower and slower. However, the imported sewage still enters continuously, and the filter holes become smaller and smaller, thereby generating a pressure difference between the inlet and outlet. When the pressure difference reaches the set value, the differential pressure transmitter transmits an electrical signal to the controller, and the control system starts the drive motor to drive the shaft to rotate through the transmission component. At the same time, the sewage outlet is opened and discharged from the sewage outlet. When the filter is cleaned, the pressure difference drops to the minimum value, and the system returns to the initial filtering state, and the system operates normally.

[0004] However, due to the harsh practical working conditions of the filter, when the filter filters the cooling water with higher temperature, scale and other particulate matter are easily attached to the filter element, and the filter element inside the filter cannot be cleaned by the internal backwash water flow, resulting in the filtering effect of the filter unable to meet practical needs, which urgently needs to be improved.

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Please also read Figures 1 to 3 The water pipe filter device for continuous casting crystallizer provided by the utility model is now described. The water pipe filter device for continuous casting crystallizer comprises a filter body 1 and a descaling assembly 2, wherein the filter body 1 comprises a receiving tube 11 connected to the water circuit of the continuous casting crystallizer; the descaling assembly 2 comprises an ultrasonic transducer 21, a vibration plate 22 is bonded to the vibration end of the ultrasonic transducer 21, the vibration plate 22 can be pressed against the outer wall of the receiving tube 11, and the ultrasonic transducer 21 can move along the axis of the receiving tube 11.

[0032] Compared with the prior art, the ultrasonic transducer 21 in the present embodiment can convert external electrical signals into ultrasonic waves, and transmit the ultrasonic waves to the interior of the accommodating tube 11 through the contact between the vibration plate 22 and the outer wall of the accommodating tube 11. When the ultrasonic waves are transmitted to the interior of the filter body 1, they can cause the liquid in the filter body 1 to accelerate movement or cavitation, so that the dirt layer is dispersed and emulsified, and the dirt layer is peeled off from the filter screen in the filter body 1, thereby achieving the purpose of cleaning the filter; not only that, the utility model can clean multiple parts of the filter body 1 by moving the ultrasonic transducer 21, thereby improving the cleaning effect of the ultrasonic transducer 21 on the filter body 1.

[0033] As for how to drive the ultrasonic transducer 21 to move, specifically, a driving component 3 is provided on one side of the accommodating tube 11, and the driving component 3 includes a driving cylinder that can be extended and retracted in the up and down directions, and the cylinder body of the driving cylinder is hinged to the top edge of the accommodating tube 11 through a hinge shaft, and the ultrasonic transducer 21 is arranged at the telescopic end of the driving cylinder, the axial direction of the hinge shaft is perpendicular to the axis of the accommodating tube 11, and an annular guide rail is coaxially provided on the edge of the accommodating tube 11, and the hinge shaft is slidably arranged on the annular guide rail; at the same time, in this case, in order to enable the vibration plate 22 to be pressed against the outer wall of the accommodating tube 11, preferably, the material of the vibration plate 22 can be set to a neodymium iron boron magnet, and the material of the accommodating tube 11 is ferromagnetic metal, so that the vibration plate 22 can be tightly adsorbed on the outer wall of the accommodating tube 11, thereby reducing the energy attenuation of ultrasonic waves during the transmission from the vibration plate 22 to the inside of the accommodating tube 11. As configured above, the utility model can utilize the rotation of the driving cylinder around the accommodating tube 11 and the extension and retraction of the driving cylinder to place the ultrasonic transducer 21 at different positions on the outer wall of the accommodating tube 11, thereby achieving the technical effect of cleaning various positions of the accommodating tube 11.

[0034] The above embodiment has a relatively complex structure during specific implementation. During specific implementation, in combination with the specifications of the filter, when adapting to a filter with a smaller specification, only an ultrasonic transducer 21 is provided on one side of the filter to meet the cleaning requirements of the filter element 12. In view of the above working conditions, in some embodiments, the structural arrangement of the drive assembly 3 is simplified. Specifically, the drive assembly 3 includes a screw nut mechanism 31 and a first mounting plate 32. The screw nut mechanism 31 includes a first transmission screw 311, a connecting block 313 and a second transmission screw 312. The first transmission screw 311 extends along the axial direction of the accommodating cylinder 11. It is arranged on the outer periphery of the accommodating cylinder 11, the connecting block 313 is threadedly adapted to the outer periphery of the first transmission screw 311, the second transmission screw 312 penetrates the connecting block 313 along its own axial direction and is threadedly adapted to the connecting block 313, and the second transmission screw 312 is perpendicular to the first transmission screw 311, the second transmission screw 312 has a first connecting end located between the connecting block 313 and the filter body 1, the first connecting end is rotatably connected to the first mounting plate 32, the ultrasonic transducer 21 is arranged on the first mounting plate 32, and the first mounting plate 32 can approach or move away from the outer wall of the accommodating cylinder 11 as the second transmission screw 312 rotates.

[0035] In this embodiment, the setting of the screw nut mechanism 31 can enhance the fixing effect of the ultrasonic transducer 21 and prevent the connection between the ultrasonic transducer 21 and the accommodating tube 11 from being too loose. In addition, the utility model can make the vibration plate 22 close to the outer wall of the accommodating tube 11 by rotating the second transmission screw 312, which is conducive to reducing the energy loss in the process of ultrasonic waves being transmitted from the vibration plate 22 to the inside of the accommodating tube 11. Of course, in order to make the connection between the vibration plate 22 and the accommodating tube 11 more secure, a technical solution similar to that in the above embodiment can also be adopted, in which the material of the vibration plate 22 is set to a neodymium iron boron magnet, and the material of the accommodating tube 11 is set to a ferromagnetic metal, so as to prevent the vibration plate 22 from generating uncontrollable displacement with the accommodating tube 11 during high-frequency vibration.

[0036] It should be noted that, based on the above embodiments, in some embodiments, a driving motor 33 for driving the two first transmission screws 311 to rotate is provided at the top of the accommodating tube 11. In this embodiment, the first transmission screw 311 can be rotated with its own axis as the rotation center by the rotation of the driving motor 33, thereby driving the connecting block 313 to move along the axis of the first transmission screw 311. During the movement, the connecting block 313 drives the ultrasonic transducer 21 to move along the axis of the accommodating tube 11, thereby being able to clean the filter element 12 inside the accommodating tube 11 at different positions on the accommodating tube 11.

[0037] Based on the above embodiment, an alternative implementation is provided. Specifically, the first transmission screws 311 are two arranged side by side, and both first transmission screws 311 pass through the connection block 313 along their own axes. In this embodiment, the two first transmission screws 311 arranged side by side can not only guide and position the up and down movement of the connection block 313, but also prevent the connection block 313 from rotating around the axis of any one of the first transmission screws 311, thereby improving the guidance and positioning accuracy of the first transmission screws 311 on the connection block 313 in this embodiment.

[0038] Optionally, in a possible implementation, there are multiple ultrasonic transducers 21, and each vibration plate 22 is integrally connected; such a configuration can not only improve the cleaning effect of the present embodiment on the filter element 12 in the accommodating cylinder 11, but the integrally connected vibration plates 22 can also fix each ultrasonic transducer 21 to prevent the ultrasonic transducer 21 from deviating during high-frequency vibration.

[0039] In some embodiments, a connecting spline 3121 is provided at one end of the second transmission lead screw 312 away from the accommodating cylinder 11, and the connecting spline 3121 is connected to a driving shaft that drives the second transmission lead screw 312 to rotate so as to rotate the second transmission lead screw 312. At the same time, in order to prevent the first mounting plate 32 from rotating around the second transmission lead screw 312 during the process of the second transmission lead screw 312 driving the first mounting plate 32 to move, in some embodiments, a guide rod 314 is provided on the first mounting plate 32, and the guide rod 314 is slidably inserted in the connecting block 313 along its own length direction, and the guide rod 314 is parallel to the second transmission lead screw 312. In this way, the present embodiment can use the guide rod 314 to guide the movement of the first mounting plate 32, and prevent the first mounting plate 32 from generating uncontrollable displacement during the movement.

[0041] Compared with the prior art, the continuous casting crystallizer in the utility model has all the benefits of the above-mentioned continuous casting crystallizer water pipe filtering device, which will not be described here in detail.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
