Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ore dressing, in particular to a thickener overflow system and an ore dressing system. Background Art
[0002] The function of the thickener is to thicken the ore pulp. The thickened high-concentration ore pulp flows out from the bottom discharge pipe, and the clean water overflows from the top of the thickener. Under most conditions, this overflow water will be pumped to the high-level water tank for reuse through the pipeline pump. In the early stage of construction, the pipeline pump and the supporting pipelines are determined after calculation. If the front-end process changes, resulting in an increase in the amount of ore and water entering the thickener, then the pipeline pump and the pipeline overflow water system need to be modified.
[0003] In the past, the renovation method was to directly replace the pipeline pump and pipeline. After the pipeline pump was replaced, the original pump and pipeline were basically abandoned, resulting in waste. In addition, the pipeline laying project is very large, requiring a lot of manpower, material and financial resources, especially for sites with poor construction environment, the construction is more difficult, and the construction period is naturally increased. For on-site production, time is very important. The time for the renovation of the overflow water system will delay the progress of the new process and bring certain economic losses.
[0004] In view of this, the present utility model is proposed. Utility Model Content

[0018] A mineral processing system comprises a thickener overflow system as described above.
[0019] Preferably, the water tank is a shaft sealing water tank or a cooling water tank.
[0020] Compared with the prior art, the thickener overflow system and ore dressing system proposed by the utility model have the following advantages:
[0021] 1. In the thickener overflow system and mineral processing system proposed by the utility model, the original pipeline pump and pipeline are maintained unchanged, and an overflow water system is laid, which adopts a sewage pump and a PE pipeline.

[0023] 3. In the thickener overflow system and mineral processing system proposed by the utility model, the working characteristics of the sewage pump need to be completely under the water surface to ensure its heat dissipation. Therefore, two working positions are set by using a floating switch. Position 1 is at 1m, which is the lowest pump start water level.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.
[0032] like Figure 1As shown, an embodiment of the utility model provides a thickener overflow system, including a thickener body 100, an overflow weir 200 is arranged above the thickener body 100, a first overflow port and a second overflow port are respectively opened on the overflow weir 200, the first overflow port is connected to the first pipeline pump 300 through a first overflow pipe 400, and the second overflow port is connected to the water tank 600 through a second overflow pipe 500, and a sewage pump 610 is arranged in the water tank 600.
[0033] In the thickener overflow system proposed by the utility model, the original pipeline pump and pipeline are maintained unchanged, and an overflow water system is laid, using a sewage pump 610 and a PE pipeline. The sewage pump 610 is small in size and does not need to be separately made into a foundation, and can be directly placed in the water tank 600. In this way, the newly added overflow water system has a lower investment, a faster construction speed, and can better use the water volume fluctuation during the process debugging process, and can also better save energy.
[0034] In addition, in the preferred embodiments of the above embodiments, quick connectors are used to connect the second overflow port and the second overflow pipe 500, the second overflow pipe 500 and the water tank 600, the sewage pump 610 and its outlet pipe, etc., so that the use of quick connectors in the utility model can enable faster construction, and its advantages can be more prominent under complex terrain conditions compared to flange connections or welding.
[0035] like Figure 2 As shown, the embodiment of the utility model provides a thickener overflow system. The working characteristics of the sewage pump 610 require it to be completely under the water surface to ensure its heat dissipation. Therefore, a check valve 620 is provided on the outlet pipe of the sewage pump 610, so that the water in the outlet pipe can flow back to the water tank 600 when the pump is stopped, thereby ensuring that there is always water in the water tank 600.
[0036] The embodiment of the utility model provides a thickener overflow system, wherein the number of the sewage pumps 610 is three, two in use and one in reserve.
[0037] In addition, as mentioned above, the working characteristics of the sewage pump 610 require that it be completely under the water surface to ensure its heat dissipation; therefore, a floating switch 630 is provided in the water tank 600; the floating switch 630 includes a first switch position 640 and a second switch position 650, the first switch position 640 is located below the second switch position 650; the first switch position 640 controls the opening and closing of one sewage pump 610; the second switch position 650 controls the opening and closing of another sewage pump 610. In this way, the first switch position 640 is the lowest pump start water level, and only one sewage pump 610 can be started above this water level; when the liquid level reaches the second switch position 650, the second sewage pump 610 is started.
[0038] The embodiment of the utility model provides a thickener overflow system, the sewage pump 610 and the pipe diameter of the connected pipe are selected to be 110 mm, and the PE pipe under this pipe diameter can be coiled into 50m or 30m coils, which is convenient for transportation and installation, and the transformation efficiency is greatly increased.
[0039] The following is the specific transformation method of the applicant on site: adding 200m 3 Taking overflow water as an example, the flow rate or quantity of the sewage pump 610 can be adjusted according to the specific situation. First, a hole with a diameter of 200mm is opened from the overflow weir 200 of the thickener, and a water pipe with an inner diameter of 200mm is connected to allow the overflow water to flow to the water tank 600 below. Since the thickener has a certain height and a certain degree of construction difficulty, the overflow water pipe is made of PE material. The size of the water tank 600 is 3×1.5×1.5 meters (length×width×height), so a 6-meter steel plate is just enough to make a water tank 600. Three flow rates of 100m 3 / h sewage pump 610, 2 for 1 standby, a check valve 620 is set at the pump outlet to prevent the water in the pipeline from flowing back to the water tank 600 when the pump is stopped. The pipe diameter of the sewage pump 610 is selected to be 110mm. The PE pipe under this pipe diameter can be coiled into 50m or 30m coils, which is convenient for transportation and installation, and the transformation efficiency is greatly increased. Due to the working characteristics of the sewage pump 610, it needs to be completely under the water surface to ensure its heat dissipation. Therefore, two working positions are set using the floating switch 630. Position 1 is at 1m, which is the lowest pump start water level. Only when the water level is higher than this level can one sewage pump 610 be started; when the liquid level reaches position 2, that is, 1.3m, the second sewage pump 610 is started.
[0040] The utility model embodiment also provides a mineral processing system, comprising a thickener overflow system as described above, the thickener overflow system comprises a thickener body 100, an overflow weir 200 is arranged above the thickener body 100, a first overflow port and a second overflow port are respectively opened on the overflow weir 200, the first overflow port is connected to the first pipeline pump 300 through the first overflow pipe 400, the second overflow port is connected to the water tank 600 through the second overflow pipe 500, and a sewage pump 610 is arranged in the water tank 600.
[0041] In the mineral processing system provided by the above embodiment, the water tank 600 can also use the existing water tanks in the workshop of the mineral processing system, and can solve some production problems. For example, by using the shaft sealing water tank, the water replenishment problem of the water tank 600 can be solved; by using the cooling water tank, the flowing water can solve the heat dissipation problem of the water tank 600.
