Description

Technical Field

[0001] This utility model relates to the field of mineral processing auxiliary equipment technology, specifically a tailings water return and slag removal device. Background Technology

[0002] During the mining process, a large amount of emulsion explosives are used. The explosive casing enters the grinding and flotation system along with the ore. Since the explosive casing is made of organic hard plastic, it is difficult for the ball mill to grind it. The unground explosive casing enters the thickener along with the tailings. Due to its light weight, most of it will flow into the slag removal screen with the return water. However, since the screen hole diameter is fixed, it is difficult to filter out the explosive casing smaller than the screen hole. In the tailings return water slag removal device disclosed in patent CN221889329U, this device can effectively filter large particulate impurities in the return water; the inlet and outlet are welded to the pipes, effectively preventing return water leakage; due to the presence of the track, when the filter drawer is full of impurities, it can be manually pulled out without consuming a lot of manpower and resources; the space of the filter drawer only occupies one-fifth of the entire box, and even if it is not detected in time when the filter drawer is full of impurities, the return water will flow out from both sides of the drawer; under normal circumstances, multiple filter drawers can be equipped to improve filtration efficiency; all filter drawers in the box are filled with filter holes, greatly increasing the return water throughput.

[0003] However, in actual use, due to the large volume of tailings return water, its slag removal and purification process is not only for removing explosive casings. There are still many particulate impurities in the returned water after sedimentation. Existing equipment can easily cause the filter drawer mesh to become clogged in a short time when filtering the returned water. In this case, the staff need to frequently replace and clean the filter drawer, which not only wastes time and affects the efficiency of slag removal in returned water, but also increases labor costs. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a tailings return water slag removal device to solve the problem that the existing devices mentioned in the background art are prone to clogging of the filter drawer mesh in a short time when filtering return water. In this case, the staff need to frequently replace and clean the filter drawer, which not only wastes time and affects the return water slag removal efficiency, but also increases labor costs.

[0012] As a preferred embodiment of the tailings return water slag removal device of this utility model, a door that can be opened and closed is provided on one side of the box body, and a control panel is provided on the outside of the door.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This tailings return water slag removal device introduces the return water raw water into the flow chamber, filters it through the filter screen, and then enters the purification chamber. It is then discharged through the outlet window. Therefore, particulate impurities are mainly embedded in the filter screen surface facing the flow chamber. When the filter screen needs to be cleaned, the first water supply line is closed and the second water supply line is opened to inject clean water into the filter screen washing component. Several high-pressure scattering nozzles can perform a comprehensive reverse intensive flushing of the filter screen, which effectively squeezes out the particulate impurities embedded in the filter screen surface. At the same time, the stiff bristle brush, with the cooperation of the lifting component, can repeatedly brush the filter screen surface during the washing process, thereby further cleaning the impurities and dirt on the screen surface. This keeps the filter screen in a smooth filtration state for a long time. While automatically cleaning, it saves the time and labor costs of manual replacement and cleaning, and the return water slag removal efficiency is significantly improved.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Figures 1-3 The diagram shown is a complete structural schematic of a tailings water recycling and slag removal device according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of a tailings return water slag removal device includes a housing 100. Inside the housing 100, there is a flow chamber 110 and a purification chamber 120 adjacent to the flow chamber 110. A filter screen plate 200 is arranged between the flow chamber 110 and the purification chamber 120. Inside the purification chamber 120, there is a filter screen washing assembly 300 facing the filter screen plate 200 on one side, and a second water supply pipeline 700 arranged above the housing 100 for supplying water to the filter screen washing assembly 300. The bottom of the purification chamber 120 has a water outlet window 1201. Inside the flow chamber 110, there is a hard bristle brush 400 that is horizontally attached to the screen surface of the filter screen plate 200, and a lifting assembly 500 for moving the hard bristle brush 400 up and down. The upper end of the housing 100 is also provided with a first water supply pipeline 600 for injecting return water into the flow chamber 110.

[0022] The lowest point inside the flow chamber 110 also has a drain outlet 1101, and an electric sealing door 130 located at the bottom of the drain outlet 1101 and matching the drain outlet 1101. It can be understood that when it is necessary to discharge particulate impurities deposited at the bottom of the flow chamber 110, the system will control the electric sealing door 130 to open automatically, thereby discharging the impurities along with a small amount of water. During normal filtration, the electric sealing door 130 is in the closed state. The filter screen washing assembly 300 includes a main pipe 310 vertically fixed inside the purification chamber 120, several branch pipes 320 horizontally connected to one side of the main pipe 310, and several high-pressure scattering nozzles 330 distributed along the length of the branch pipes 320, with the several high-pressure scattering nozzles 330 facing the filter screen plate 200. The lifting assembly 500 includes a strip seat 510 for fixing the stiff bristle brush 400, a lead screw 520 that is vertically threaded to the center of the strip seat 510 by a nut and rotatably mounted on the inner side of the flow chamber 110, a rotary reciprocating motor 530 located at the upper end of the housing 100 and used to drive the lead screw 520 to rotate axially, a sliding sleeve 540 fixed to both ends of the strip seat 510, and a guide slide column 550 that slides vertically through the inner side of the sliding sleeve 540 and is fixed on the inner side of the flow chamber 110. Specifically, in this embodiment, the recycled water is introduced into the flow chamber 110, filtered by the filter plate 200, and then enters the purification chamber 120, before being discharged through the outlet window 1201. Therefore, particulate impurities are mainly embedded on the filter surface of the filter plate 200 facing the flow chamber 110. When cleaning the filter plate 200 is required, the first water supply line 600 is immediately closed, while the second water supply line 700 is opened and clean water is injected into the filter washing assembly 300. Several high-pressure spray nozzles 330 can then be used to clean the filter. The screen plate 200 undergoes a comprehensive reverse intensive flushing, effectively squeezing out particulate impurities embedded in the filter screen surface. At the same time, the stiff bristle brush 400, in conjunction with the lifting component 500, can repeatedly brush the filter screen surface of the screen plate 200 during the flushing process, thereby further cleaning the impurities and dirt on the screen surface. This ensures that the filter screen remains in a smooth filtration state for a long time. The automatic cleaning eliminates the time and labor costs associated with manual replacement and cleaning, and significantly improves the efficiency of water return and slag removal.

[0023] Preferably, the first water supply pipeline 600 further includes a return water pipeline 610 with one end connected to the flow chamber 110 and the other end connected to the return water source, a first water pump 620 installed on the return water pipeline 610, and an ultrasonic level gauge 630 installed on the top of the flow chamber 110. It is understood that the ultrasonic level gauge 630 can monitor the water and water level entering the flow chamber 110 in real time, preventing excessive water flow from exceeding the load and preventing insufficient water flow from failing to fully utilize the filter screen 200.

[0024] Preferably, the second water supply pipeline 700 further includes a clean water pipe 710 connected at one end to the main pipe 310, and a second water pump 720 and a water pressure sensor 730 installed on the clean water pipe 710. Through the cooperation of the clean water pipe 710, the second water pump 720, and the water pressure sensor 730, the unit volume of water injected into the main pipe 310 and the water pressure can be monitored, and the system can operate in conjunction with the control system.

[0025] Preferably, a door 140 that can be opened and closed is further provided on one side of the housing 100, and a control panel 800 is provided on the outside of the door 140. It is understood that after the door 140 is opened, the filter screen 200 and structural components inside the housing 100 can be easily replaced and maintained. It is understood that there is a sealing structure between the door 140 and the opening of the housing 100. In addition, the operator can operate and set the various operating units of the slag removal device through the control panel 800.

[0026] In summary, the tailings return water slag removal device of this embodiment, during use, introduces the return water raw water into the flow chamber 110, filters it through the filter screen plate 200, and then enters the purification chamber 120, subsequently discharging it through the outlet window 1201. Therefore, particulate impurities are mainly embedded on the screen surface of the filter screen plate 200 facing the flow chamber 110. When it is necessary to clean the filter screen plate 200, the first water supply line 600 is immediately closed, while the second water supply line 700 is opened and clean water is injected into the filter screen washing assembly 300, passing through several high-pressure filters. The pressure-scattering nozzle 330 can perform a comprehensive reverse intensive rinsing of the filter screen 200, effectively squeezing out the particulate impurities embedded in the filter screen surface. At the same time, the stiff bristle brush 400, in conjunction with the lifting component 500, can repeatedly brush the filter screen surface of the filter screen 200 during the rinsing process, thereby further cleaning the impurities and dirt on the screen surface, keeping the filter screen in a smooth filtration state for a long time. While automatically cleaning, it saves the time and labor costs associated with manual replacement and cleaning.

[0027] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
