Description

TECHNICAL FIELD

[0001] The application relates to the technical field of domestic sewage treatment, and in particular relates to a heavy metal sewage separation device. BACKGROUND

[0002] Metal sewage separation refers to the process of separating metal ions (such as mercury, cadmium, lead, chromium, copper, zinc, etc.) or other metal pollutants from sewage through various physical, chemical or biological methods. The purpose of this process is to reduce the concentration of metal ions in the sewage, so that it meets the discharge standard or realizes resource utilization, thereby reducing the negative impact on the environment and the ecosystem. Metal sewage separation technology is diverse, including but not limited to precipitation method, ion exchange method, microbial adsorption method, phytoremediation method and membrane separation technology, etc. The specific selection depends on the composition, concentration, treatment requirements, and economic and environmental factors of the sewage.

[0003] During the precipitation process of metal sewage, it is necessary to fully contact with the reducing agent for reaction. However, during the stirring process, the metal sewage cannot be subjected to multi-layer stirring, which limits the efficiency of metal sewage separation. In addition, during the separation process, the metal will deposit on the inner wall of the treatment tank, which affects the process of metal sewage separation.

The adjusting pool is connected with an ozone generating device for pre-oxidizing the liquid in the adjusting pool. The adjusting pool and the reaction pool are connected with a dosing device for adjusting the pH value of the liquid.

However, domestic sewage contains a large amount of garbage, which can block the reaction pipeline and reduce the reaction efficiency of removing heavy metals. In order to facilitate the removal of garbage and improve the removal efficiency of heavy metals in domestic sewage, a domestic sewage treatment device is proposed. Practical new type content

Furthermore, during the separation process, metal will be deposited on the inner wall of the treatment tank, affecting the metal wastewater separation process.

[0032] As an improvement, such as Figure 1 -Figure 6 The preferred embodiments of the present application are shown as follows:

[0036] By reversely rotating the tank body, the spiral ring plate 206 is separated from synchronous movement with the tank body, so that the spiral ring plate 206 scrapes the inner wall of the tank body and peels off the metal deposited on the inner wall of the tank body, thereby being capable of processing the metal deposited on the inner wall of the tank body in the separation process and preventing the metal from hindering the separation process of the metal sewage.

[0037] As shown in the drawings, Figure 1 With Figure 2 As shown, in this embodiment, the driving assembly 6 comprises a gear ring 601 fixedly installed on the middle part of the outer wall of the spherical tank body 1, an auxiliary gear 602 is meshingly connected to the outer wall of the gear ring 601, an auxiliary shaft 603 is fixedly installed in the auxiliary gear 602, a motor 604 is fixedly connected to the lower end of the auxiliary shaft 603, the motor 604 is fixedly installed above one end of the second arc frame 204, the positioning ring 202 connected with the first arc frame 203 and the support inclined ring plate 205 connected with the second arc frame 204 support the spherical tank body 1 containing metal sewage, so that the spherical tank body 1 can be driven by the gear ring 601 to rotate forwardly and reversely, thereby changing the working state;

[0038] The auxiliary gear 602 is rotated to drive the spherical tank body 1 provided with the gear ring 601 to rotate, so as to switch the mode of processing the metal sewage in the forward rotation and reverse rotation states, thereby improving the efficiency of the metal sewage separation and processing.

[0039] The working principle of the present application is as follows: the staff directs the metal sewage along the feeding funnel 201 into the spherical tank body 1, and then starts the motor 604 to work in the forward direction, which drives the auxiliary gear 602 to rotate in the forward direction, and the gear ring 601 connected therewith moves to drive the spherical tank body 1 to rotate in the forward direction. Under the cooperation of the ratchet ring 302, the spiral ring plate 206 in the spherical tank body 1 is driven to stir the metal sewage in the spherical tank body 1 to fully react with the reducing agent. At the same time, the inclined scraper 210 connected to the outer wall of the rotating shaft by the limiting sleeve ring 209 moves on the surface of the spiral ring plate 206. The shape of the spiral ring plate 206 is a section of thread line connected end to end, so that the inclined scraper 210 moves up and down in the spherical tank body 1, and scrapes the metal and reducing agent deposited on the surface of the spiral ring plate 206. After a certain period of time, the metal sewage in the spherical tank body 1 stops reacting with the reducing agent, and the metal ions in the metal sewage are deposited in the spherical tank body 1. At this time, the motor 604 is started to rotate in the reverse direction to drive the spherical tank body 1 to rotate. Under the cooperation of the ratchet ring 302, the spiral ring plate 206 connected by the arc plate 303 in the spherical tank body 1 stops rotating. With the rotation of the spherical tank body 1, the inner wall thereof scrapes the spiral ring plate 206 to scrape the metal deposited on the inner wall of the spherical tank body 1 and make it precipitate in the sewage, thereby completing the separation operation. The flow guide pipe 305 is opened, and the sewage flows out through the filter paper plate 304. The observation window 5 in the positioning frame 4 is observed. After the sewage is discharged, the discharge pipe is disassembled, the filter paper plate 304 in the discharge pipe 301 is taken out, the spherical tank body 1 is started in the forward direction, the inclined scraper 210 scrapes the metal on the surface of the spiral ring plate 206, and the spherical tank body 1 is discharged, thereby completing the separation operation of the metal sewage.
