Description

Technical Field

[0001] The invention relates to the technical field of heavy metal recovery from asbestos tailings, and in particular to a heavy metal ion chelation recovery device for asbestos tailings. Background Art

[0002] Asbestos tailings contain heavy metal ions. The chelation recovery device is mainly used to separate and recover the heavy metal ions in asbestos tailings.

[0003] However, in the traditional recycling process, the equipment is complex and the process is carried out step by step. As a result, the asbestos tailings need to be transported to the required area for treatment. This increases the transportation cost. Secondly, the waste generated also needs secondary treatment, which increases the difficulty of the work.

[0004] In view of this, we propose an integrated asbestos tailings heavy metal recovery device that can be processed nearby, effectively achieving initial nearby treatment and improving efficiency. Summary of the Invention

[0005] In view of the defects in the prior art, the present invention provides an asbestos tailings heavy metal ion chelation recovery device to achieve preliminary local treatment and improve efficiency.

[0006] The present invention provides an asbestos tailings heavy metal ion chelation recovery device, comprising: a centrifugal part, the centrifugal part comprising a centrifugal motor, a main cylinder and a centrifugal screen cylinder; the centrifugal screen cylinder is rotatably installed in the main cylinder and is transmission-connected to the centrifugal motor; and a pulse-type chelating agent dosing mechanism, the pulse-type chelating agent dosing mechanism is arranged above the centrifugal part and located on the centrifugal screen cylinder; the pulse-type chelating agent dosing mechanism comprises a high-frequency pulse valve, a liquid pump and a liquid tank; one end of the liquid pump is communicated with the liquid tank, and the other end of the liquid pump is communicated with one end of the high-frequency pulse valve, the chelating agent flows from the other end of the high-frequency pulse valve into the centrifugal screen cylinder, and the chelating agent in the liquid tank has a nano-magnetic carrier.

[0007] Furthermore, the centrifugal unit includes a feed cover, which is equipped with a main cover, a feed pipe, and a secondary pipe. The main cover is detachably mounted on the main cylinder, and the feed pipe passes through the main cover and is located above the centrifugal screen cylinder. The secondary pipe is located on one side of the feed pipe and communicates with the high-frequency pulse valve. In actual use, the purpose of this design is to facilitate handling and prevent dust.

[0008] Furthermore, the centrifugal part also includes an anti-collision air sleeve, which is provided on the inner wall of the main cylinder. In actual use, the purpose of this design is to increase the actual service life of the entire device and effectively reduce the impact of asbestos tailings on the inner wall.

[0009] Furthermore, the centrifugal part also includes an air pump, one end of which is connected to the anti-collision air sleeve. In actual use, the purpose of this design is to change the expansion size of the anti-collision air sleeve through the air pump, thereby changing the pressure of the main cylinder. In this way, the centrifugal effect can be further improved and a wave oscillation effect other than centrifugation can be achieved. In actual work, when the interval anti-collision air sleeve is inflated or deflated, that is, when the anti-collision air sleeve expands and the interval shrinks, the pressure in the main cylinder will be squeezed or reduced. In this way, the oscillation of the chelating agent can be accelerated, thereby facilitating its contact with the asbestos tailings. In this way, the processing efficiency of the chelating agent can be further guaranteed. In actual processing, the chelating agent introduces nano-magnetic carriers, which makes contact easier. The main component of the nano-magnetic carriers is Fe3O4. The chelating agent is recyclable by surface modification with chelating groups (-SH, -COOH).

[0010] Furthermore, the centrifugal screen cylinder further includes a heating unit, wherein the heating unit includes at least one electric heating strip, and the electric heating strip is evenly distributed on the inner wall of the centrifugal screen cylinder and is evenly distributed in a ring shape. In actual use, the purpose of this design is to increase the activity of the chelating agent and actually work at an adapted temperature.

[0011] Furthermore, the pulsed chelating agent dosing mechanism further includes a stirrer, which is installed in the liquid tank. In actual use, the purpose of this design is to enhance the activity of the chelating agent.

[0012] Furthermore, the device also includes an electromagnetic unit, which includes a magnetic field network, located within the anti-collision air sleeve of the main cylinder. In actual use, the magnetism generated by this design can be enhanced together with the aforementioned nanomagnetic carriers. The magnetic field strengthens the nanomagnetic carriers, thereby increasing their reaction efficiency with heavy metal ions in asbestos tailings and accelerating recovery. This effectively improves the utilization rate compared to traditional chelating agents without nanomagnetic carriers.

[0013] Furthermore, the electromagnetic unit also includes an electrode. The centrifugal screen drum is provided with a rotating shaft, one end of which is drivingly connected to the centrifugal motor. The electrode is fixedly mounted on the other end of the rotating shaft and is located within the centrifugal screen drum. In actual use, the purpose of this design is to achieve electric shock and accelerate the recovery of heavy metal ions.

[0014] From the above technical solution, it can be seen that the beneficial effects of the asbestos tailings heavy metal ion chelation recovery device provided by the present invention are:

[0015] (1) In actual application, the overall device adopted in this design is effective in locating the device near the asbestos tailings, so as to facilitate local treatment, thereby achieving the goal of preliminary treatment;

[0016] (2) The pulsed chelating agent dosing mechanism used can achieve sustainable interval feeding through a high-frequency pulse valve, effectively ensuring continuous operation.

[0017] (3) The chelating agent in the liquid tank has nano-magnetic carriers, which can effectively improve the recovery efficiency of heavy metal ions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0024] The embodiment is basically as shown in the attached Figures 1 to 2 As shown:

[0025] like Figure 1-Figure 2 As shown, the asbestos tailings heavy metal ion chelation recovery device provided in this embodiment can achieve preliminary local treatment and improve efficiency.

[0026] The present invention provides an asbestos tailings heavy metal ion chelation recovery device, comprising: a centrifugal part 1, the centrifugal part 1 comprising a centrifugal motor 11, a main cylinder 12 and a centrifugal screen cylinder 13; the centrifugal screen cylinder 13 is rotatably installed in the main cylinder 12 and is transmission-connected to the centrifugal motor 11; and a pulsed chelating agent dosing mechanism 2, the pulsed chelating agent dosing mechanism 2 is arranged above the centrifugal part 1 and located on the centrifugal screen cylinder 13; the pulsed chelating agent dosing mechanism 2 comprises a high-frequency pulse valve 21, a liquid pump 22 and a liquid tank 23; one end of the liquid pump 22 is communicated with the liquid tank 23, and the other end of the liquid pump 22 is communicated with one end of the high-frequency pulse valve 21, the chelating agent flows from the other end of the high-frequency pulse valve 21 into the centrifugal screen cylinder 13, and the chelating agent in the liquid tank 23 has a nanomagnetic carrier 200. In actual application, the overall device adopted in this design effectively facilitates the installation of the device near the asbestos tailings, which is convenient for local treatment. In this way, preliminary treatment can be achieved; and the pulsed chelating agent dosing mechanism 2 adopted can achieve sustainable interval feeding through the high-frequency pulse valve 21, effectively ensuring continuous operation, and the chelating agent in the liquid tank 23 has nano-magnetic carriers 200, which can effectively improve the recovery efficiency of heavy metal ions.

[0027] In this embodiment, the centrifugal unit 1 includes an addition cover 14, which is equipped with a main cover 141, an addition pipe 142, and a secondary pipe 143. The main cover 141 is detachably mounted on the main cylinder 12, and the addition pipe 142 passes through the main cover 141 and is located above the centrifugal screen cylinder 13. The secondary pipe 143 is located on one side of the addition pipe 142 and communicates with the high-frequency pulse valve 21. In actual use, this design facilitates handling and prevents dust.

[0028] In this embodiment, the centrifugal part 1 further includes an anti-collision air sleeve 15, which is provided on the inner wall of the main cylinder 12. In actual use, the purpose of this design is to increase the actual service life of the entire device and effectively reduce the impact of asbestos tailings on the inner wall.

[0029] In this embodiment, the centrifugal unit 1 further includes an air pump 16, one end of which is in communication with the anti-collision air sleeve 15. In actual use, the purpose of this design is to change the expansion size of the anti-collision air sleeve 15 through the air pump 16, thereby changing the pressure of the main cylinder 12. In this way, the centrifugal effect can be further improved and a wave oscillation effect other than centrifugation can be achieved. In actual operation, when the anti-collision air sleeve 15 is inflated or deflated, that is, when the anti-collision air sleeve 15 expands and the intervals are contracted, it squeezes or reduces the pressure in the main cylinder 12. This can accelerate the oscillation of the chelating agent and facilitate its contact with the asbestos tailings. This can further ensure the treatment efficiency of the chelating agent.

In practical applications, the magnetism generated by this design can be enhanced together with the aforementioned nanomagnetic carriers 200. The magnetic field strengthens the nanomagnetic carriers 200, thereby enhancing their reaction with the heavy metal ions in the asbestos tailings and accelerating their recovery. This effectively improves the utilization rate compared to conventional chelating agents without nanomagnetic carriers 200.

[0033] In this embodiment, the electromagnetic unit 4 further includes an electrode 42. The centrifugal screen drum 13 is provided with a rotating shaft 131. One end of the rotating shaft 131 is in driving connection with the centrifugal motor 11. The electrode 42 is fixedly mounted on the other end of the rotating shaft 131 and is located within the centrifugal screen drum 13. In actual use, the purpose of this design is to achieve electric shock and accelerate the recovery of heavy metal ions.

[0034] In summary, this asbestos tailings heavy metal ion chelation recovery device is not only reasonably designed, but also simple to operate, and can effectively achieve local treatment. The use of nanomagnetic carrier 200 can effectively improve the recovery efficiency of heavy metal ions; and the use of electric field and magnetic field for dual reinforcement can further improve the heavy metal ion recovery efficiency of asbestos tailings. Therefore, this device is suitable for industry promotion.
