Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an ion-type rare earth wastewater treatment device. Background Technology

[0002] Currently, after rare earths are mined and processed industrially, a large amount of rare earth wastewater is generated. In order to ensure that the environment is not polluted, the rare earth wastewater needs to be collected and discharged. However, traditional rare earth wastewater contains a large amount of solids and fine particulate impurities before treatment. If it is not filtered in advance, it will cause great inconvenience to subsequent purification treatment.

[0003] However, existing rare earth wastewater filtration devices have poor filtration efficiency and are inconvenient to clean later. Therefore, a rare earth wastewater treatment device, such as the one with patent number CN214654051U, was developed to address these issues. However, this device has the following drawbacks: due to the potentially large size of the filter cartridges and the depth of the wastewater tank, users must lean forward into the tank to retrieve or place multiple filter cartridges at the bottom, which undoubtedly increases labor intensity and makes retrieval inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide an ion-type rare earth wastewater treatment device.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] An ion-type rare earth wastewater treatment device includes a rectangular box. Inlet and outlet pipes are respectively installed at the upper and lower ends of the side walls of the box. A lead screw driven by a motor is vertically installed in the middle of the box. Multiple sets of filter mechanisms screwed to the lead screw are arranged side-by-side in the box. Each filter mechanism includes a mounting base adapted to the lead screw and installed within the box. A flow guide groove is provided on the top of the mounting base. The flow guide groove has a truncated pyramidal structure and is inverted. A cylindrical filter frame extending to the bottom of the mounting base is provided at the middle of the bottom of the flow guide groove. A screw tube screwed to the lead screw is provided on the filter frame. Bearings are provided on the upper and lower sides of the bottom wall of the filter frame. Two sets of bearings are respectively provided with L-shaped scrapers tightly attached to the corresponding inner and outer side walls of the filter frame.

[0007] Preferably, a support portion for supporting the lowest mounting base is arranged around the inside of the housing.

[0008] Preferably, the top of each mounting base is provided with multiple sets of T-shaped rods, wherein the T-shaped rods abut against the bottom of the mounting base above them.

[0009] Preferably, the filter frame is fixedly connected to the corresponding mounting base, wherein the side wall aperture of the upper filter frame is larger than the side wall aperture of the lower filter frame.

[0010] Preferably, the top of the housing is provided with a cover plate, the water inlet pipe is provided on the side wall of the housing at the top of the uppermost mounting base, and the water outlet pipe is provided on the side wall of the housing at the bottom of the lowermost mounting base.

[0011] Preferably, the spiral tube is fixedly connected to the bottom wall of the corresponding filter frame, and a reinforcing rod is radially provided at the top end of the spiral tube and connected to the side wall of the corresponding guide groove. The reinforcing rod is located above the corresponding L-shaped scraper.

[0012] The beneficial effects of this invention are as follows: This invention uses a motor to drive a lead screw to rotate in both directions, so that the lead screw drives multiple sets of filter mechanisms to slide into the housing in an orderly manner, or to slide the filter mechanism out of the housing upwards, thereby facilitating the removal and placement of the filter mechanism and reducing labor intensity. Furthermore, after the filter mechanism is removed, the L-shaped scraper can be rotated to rotate on the bearing. The rotating L-shaped scraper can scrape and clean the entire inner or outer side wall of the filter frame, thereby effectively removing impurities adhering to its surface.

[0016] The following examples, in conjunction with the appendix, illustrate the concepts. Figure 1-2 The technical solution of the present invention will be further described in detail below.

[0017] An ion-type rare earth wastewater treatment device includes a rectangular box 1, with an inlet pipe 2 and an outlet pipe 3 respectively installed at the upper and lower ends of the side wall of the box 1.

[0018] A lead screw 4 driven by a motor 5 is vertically arranged in the middle of the housing 1. Multiple filter mechanisms 6, which are screwed to the lead screw 4, are arranged in parallel in the upper and lower parts of the housing 1. Each filter mechanism 6 includes a mounting base 61 that is adapted to it and is located in the housing 1. A flow guide groove 62 is provided on the top of the mounting base 61. The flow guide groove 62 has a truncated quadrangular structure and is upside down. A cylindrical filter frame 63 extending to the bottom of the mounting base 61 is provided in the middle of the bottom of the flow guide groove 62. The filter frame 63 is fixedly connected to the corresponding mounting base 61. The side wall aperture of the upper filter frame 63 is larger than that of the lower filter frame 63. A screw tube 64 that is screwed to the lead screw 4 is provided on the filter frame 63.

[0019] The spiral tube 64 is provided with bearings 7 located on the upper and lower sides of the bottom wall of the filter frame 63, and L-shaped scrapers 8 are respectively provided on the two sets of bearings 7, which are closely attached to the corresponding inner and outer side walls of the filter frame 63.

[0020] In this embodiment, a support portion 9 is arranged around the inside of the housing 1 to support the lowest mounting base 61. The support portion 9 provides support and fixation for the lowest mounting base 61, thereby improving its stability.

[0021] like Figure 1 As shown, each mounting base 61 has multiple sets of T-shaped rods 10 vertically arranged on its top, with the T-shaped rods 10 abutting against the bottom of the mounting base 61 above them. The lower mounting base 61 supports and fixes the upper mounting base 61 through the T-shaped rods 10. When the filter mechanism 6 slowly slides out from the top opening of the housing 1, people can also remove the filter mechanism 6 from the housing 1 by holding the T-shaped rods 10.

[0022] like Figure 1 As shown, the top of the housing 1 is provided with a cover plate 11, the water inlet pipe 2 is provided on the side wall of the housing 1 at the top of the uppermost mounting base 61, and the water outlet pipe 3 is provided on the side wall of the housing 1 at the bottom of the lowermost mounting base 61.

[0023] In this embodiment, the solenoid 64 is fixedly connected to the bottom wall of the corresponding filter frame 63. A reinforcing rod is radially provided at the top of the solenoid 64 and connected to the side wall of the corresponding guide groove 62. The reinforcing rod is located above the corresponding L-shaped scraper 8. The mounting base 61 strengthens the stability of the solenoid 64 through the reinforcing rod to prevent it from swinging due to a large area of ​​suspension above it. Furthermore, because it is located above the L-shaped scraper 8, the reinforcing rod will not affect the rotation of the L-shaped scraper 8 inside the filter frame 63.

[0024] The method of using this invention is as follows: During installation, the filter mechanism 6 is placed inside the top of the open housing 1. At this time, the side wall of the housing 1 locks the mounting base 61 in the filter mechanism 6 to prevent it from rotating. Simultaneously, the filter mechanism 6 is pressed so that the internal screw tube 64 contacts the top of the lead screw 4, with the top of the lead screw 4 inserted into the bottom opening of the screw tube 64. Then, the motor 5 drives the lead screw 4 to rotate and screw it into the screw tube 64, thereby driving the filter mechanism 6 to slowly move down inside the housing 1. When the filter mechanism 6 has moved down to a certain extent, a new filter mechanism 6 is placed in. Through the above method, the screw tubes 64 in the multiple sets of filter mechanisms 6 are screwed into the lead screw 4. The rotating lead screw 4 drives the filter mechanism 6 to slowly slide into the bottom of the housing 1, and finally... Figure 1 As shown, the support part 9 supports the lower mounting seat 61, and the lower mounting seat 61 supports and fixes the upper mounting seat 61 through the T-shaped rod 10. The screw tube 64, which is screwed to the screw rod 4, can support and fix the middle part of the filter mechanism 6, thereby effectively improving the stability of the filter mechanism 6 and preventing it from sliding out of the box 1 without human intervention.

[0025] Wastewater is introduced into the housing 1 through the inlet pipe 2 and filtered step by step by multiple filter frames 63 with different pore sizes. Wastewater falling on the mounting base 61 flows into the filter frame 63 through the inclined surface of the guide channel 62. Finally, the filtered liquid is discharged through the outlet pipe 3.

[0026] When it is necessary to clean the impurities on the filter frame 63, the motor 5 drives the lead screw 4 to reverse inside the solenoid 64, thereby driving multiple sets of filter mechanisms 6 to move slowly upward inside the housing 1, so that the filter mechanism 6 is moved to the top opening of the housing 1. After the solenoid 64 in the filter mechanism 6 is separated from the lead screw 4, it can be removed from the top opening of the housing 1 for cleaning, which facilitates the removal of multiple sets of filter mechanisms 6 inside the housing 1. After the filter mechanism 6 is removed, the L-shaped scraper 8 can be rotated to rotate on the bearing 7. The rotating L-shaped scraper 8 can scrape and clean the entire inner or outer side wall of the filter frame 63, thereby effectively removing the impurities adhering to its surface.

[0027] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
