Switch valves are installed on the inlet section and the two outlet sections of the three-way pipe. The magnetic separator also has a return outlet and a sludge discharge outlet. The return outlet of the magnetic separator is connected to the recovery outlet of the raw material tank via a return pipe. A switch valve is installed on the return outlet or return pipe of the magnetic separator.

Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figure 1As shown, this embodiment provides a slurry waste recycling system, including a raw material tank 10, an iron separator 20, and a finished product tank 30. The raw material tank 10 has a waste inlet, a discharge outlet, and a recycling outlet. The waste inlet of the raw material tank 10 is used to input waste. The discharge outlet of the raw material tank 10 is connected to the inlet end of the iron separator 20 through a discharge pipe 41. A conveying pump 50 is installed on the discharge pipe 41. The iron separator 20 has an inlet end, a discharge end, a return outlet, and a sewage outlet. The iron removal mechanism of the iron separator 20 is existing technology, and the specific iron removal operation will not be described in detail here. The discharge end of the iron separator 20 is the highest. The slurry entering the iron separator 20 from the inlet end is discharged from the high-level discharge end after the iron removal operation. The discharge end of the iron separator 20 is connected to the recovery port of the raw material tank 10 and the input end of the finished product tank 30 respectively through a three-way pipe 42 with one inlet and two outlets. The inlet section 421 and the two outlet sections (referring to the first outlet section 422 and the second outlet section 423) of the three-way pipe 42 are all equipped with switch valves. Specifically, the inlet section 421 of the three-way pipe 42 is connected to the discharge end of the iron separator 20 and is equipped with a switch valve 64, the first outlet section 422 of the three-way pipe 42 is connected to the recovery port of the raw material tank 10 and is equipped with a switch valve 65, and the second outlet section 423 of the three-way pipe 42 is connected to the input end of the finished product tank 30 and is equipped with a switch valve 66.

[0023] The iron separator 20 also has a return port and a drain port. The return port of the iron separator 20 is connected to the recovery port of the raw material tank 10 through a return pipe 43. The return port or the return pipe 43 of the iron separator 20 is equipped with a switch valve (not shown). In this embodiment, the switch valve is installed at the return port of the iron separator 20. The drain port of the iron separator 20 is located at the bottom of the iron separator 20. The drain port of the iron separator 20 is connected to a drain pipe. A switch valve 67 is installed on the drain pipe.

[0024] Using the slurry waste recycling system of this application, slurry waste is input into the raw material tank 10 from the waste inlet. The conveying pump 50 transports the slurry in the raw material tank 10 to the iron separator 20, where iron removal is performed. After iron removal, the slurry returns to the raw material tank 10 through the three-way pipe 42. At this time, the switch valve 64 of the inlet section 421 and the switch valve 65 of the first outlet section 422 of the three-way pipe 42 are opened, while the switch valve 66 of the second outlet section 423 is closed. This process is repeated until the slurry meets the standards. Specifically, sampling ports can be set at the iron separator 20 or other locations to sample and analyze the samples. The qualified slurry is output from the iron separator 20 to the finished product tank 30 through the three-way pipe 42. At this time, the switch valve 64 of the inlet section 421 and the switch valve 66 of the second outlet section 423 of the three-way pipe 42 are opened, while the switch valve 65 of the first outlet section 422 is closed, completing the iron removal operation of the slurry waste. Meanwhile, when the iron separator 20 needs cleaning, the slurry inside the iron separator 20 flows back to the raw material tank 10 from the return port through the return pipe 43. At this time, the switch valve at the return port is opened to empty the slurry inside the iron separator 20; then, the switch valve 67 on the drain pipe is opened for cleaning and sewage discharge. The slurry waste recycling system of this application has high iron removal efficiency and a relatively simple structural design, making it easy to implement.

[0025] Furthermore, in this embodiment, the waste inlet of the raw material tank 10 is provided with a switch valve 61, which can be used to control the opening and closing of the waste inlet of the raw material tank 10, so as to prevent new slurry waste from being input from the waste inlet during the iron removal process.

[0026] Furthermore, in this embodiment, the discharge pipe 41 is provided with shock absorbers 51 at both ends of the conveying pump 50. The shock absorbers 51 can effectively dampen the vibrations generated by the operation of the conveying pump 50, thus protecting the connection and operation of other components. Specifically, in this embodiment, the shock absorber 51 is a flexible hose section, such as a rubber hose in the prior art. The flexible hose section is connected in series with the discharge pipe 41, serving as part of the pipeline and playing both the role of effective shock absorption and transmission.

[0027] The discharge pipe 41 is equipped with a switch valve 62 at the front end of the discharge port connected to the raw material tank 10 and a switch valve 63 at the rear end of the feed end connected to the iron separator 20; it can separately control the output of the raw material tank 10 and the input of the iron separator 20, which facilitates the maintenance and replacement of components such as the conveying pump 50 in the middle section.

[0028] The bottom of the finished product tank 30 is provided with a discharge pipe, and a switch valve 68 is provided on the discharge pipe. When it is necessary to output the slurry in the finished product tank 30, the switch valve 68 can be opened to achieve the output.

[0029] The raw material tank 10 is equipped with a stirrer 11, and the finished product tank 30 is equipped with a stirrer 31. These mechanisms can stir the slurry, preventing slurry from being unable to be discharged from dead zones.

[0030] Furthermore, it also includes a controller, which connects to the raw material tank 10, the iron separator 20, the finished product tank 30, the conveying pump 50, and various switching valves (i.e., switching valves 61, 62, 63, 64, 65, 66, 67, 68, and the switching valve located at the return port of the iron separator 20). This controller coordinates the operation of the raw material tank 10, the iron separator 20, the finished product tank 30, the conveying pump 50, and the aforementioned switching valves. Specifically, all of the aforementioned switching valves are solenoid valves, achieving electric drive.

[0031] When slurry waste is input, the controller controls the opening of switch valve 61 and the closing of switch valve 62; the waste is input into the raw material tank 10 from the waste inlet. During iron removal, the controller controls the agitator 11 of the raw material tank 10 to perform agitation, controls the closing of switch valves 61, 66, 67, 68 and the return port switch valve of the iron separator 20, and opens the iron separator 20, the conveying pump 50, and switch valves 62, 63, 64, 65; under the action of the conveying pump 50, the slurry in the raw material tank 10 is input into the iron separator 20 through the discharge pipe 41, where iron removal is performed, and then passes through the inlet section 421 of the three-way pipe 42 and... The first outlet pipe section 422 returns the slurry to the raw material tank 10, and this cycle continues until the slurry meets the iron removal standard. Afterward, the controller closes the switch valve 65 and opens the switch valve 66, allowing the slurry in the iron separator 20 to be fed into the finished product tank 30 via the inlet pipe section 421 and the second outlet pipe section 423 of the three-way pipe 42. When the slurry in the finished product tank 30 reaches a certain volume, the controller opens the switch valve 68 and activates the agitator 31 in the finished product tank 30 to output the slurry. When the iron separator 20 needs cleaning, the controller closes the conveying pump 50 and the switch valves 62, 63, and 64, and opens the switch valve at the return port of the iron separator 20, allowing the residual slurry in the iron separator 20 to return to the raw material tank 10 via the return pipe 43. After the return is complete, the switch valve at the return port of the iron separator 20 is closed, and the switch valve 67 is opened, thereby cleaning and discharging the sludge from the iron separator 20.

[0032] Specifically, this controller is existing technology and can be a PLC controller or similar technology, which will not be described in detail here.

[0033] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
