technical field

The utility model relates to a mud-water separation tank capable of separating mud water. The utility model also relates to a method for separating mud and water by using the mud-water separation tank.

Background technique

The traditional mud separation system generally includes a flocculation tank, a mud filter press device and a drainage device. After the mud enters the flocculation tank, flocculant and lime need to be manually added. Because the mixing of the flocculant and lime with the mud needs to be relatively uniform to achieve the ideal muddy water Separation and stratification effect, but manual stirring and mixing basically cannot meet the requirements of uniform mixing.

Utility model content

In view of the deficiencies in the background technology, the technical problem to be solved by the utility model is to provide a mud-water separation tank that can better realize mud-water separation.

The utility model is completed by adopting the following technical scheme: the mud-water separation tank includes a main tank body with an inner cavity, and the upper part of the inner cavity of the main tank is provided with a plurality of filter suction ends, and the filter suction end is equipped with a net Grid support and filter cloth, multiple filter suction ends are connected in parallel on the suction pipe, and the suction pipe is equipped with a suction pump; the upper end of the main tank is provided with a spiral coil, and the outer end of the coil is connected to the mud delivery pipe. Generally, the main tank is fixedly provided with a downpipe connected to the inner end of the coil, and the end of the downpipe opens toward the inner cavity, and a screw conveyor belt is fixedly set in the mud delivery pipe, and the outer end of the screw conveyor belt is equipped with a mud A delivery pump, the lower end of the main tank has a mud discharge outlet.

The mud-water separation tank provided by the utility model has the following advantages: 1. The spiral conveyor belt in the spiral coil pipe and the mud conveying pipe makes the uniform mixing effect of the mud and flocculant better, which is mainly reflected in the growth of the mixing pipeline and the mixing channel 2. The use of tanks to separate mud can facilitate the quantitative input of mud, output of water and mud, improve the efficiency of mud-water separation, and increase the discharge of separated water; 3. The suction pipe is equipped with a filter suction with filtering function end, so that the discharged water is cleaner and can be used without sedimentation and other treatment.

Detailed ways

The accompanying drawings show the technical solution of the utility model and its embodiments, and the details and working principles of the embodiments will be further described below in conjunction with the accompanying drawings.

With reference to shown in Fig. 1, the mud-water separation tank that the utility model provides, comprises main tank body 1, has inner cavity in the main tank body 1, and a plurality of filter water suction ends 2 are arranged on the upper part of described main tank body 1 inner cavity, filters The water suction end 2 is equipped with a grid support 3 and a filter cloth 4, and a plurality of filter water suction ends 2 are connected in parallel on the water suction pipe 5, and the water suction pipe 5 is equipped with a water suction pump 6; the upper end of the main tank body 1 is provided with a spiral coil 7. The outer end of the coil pipe 7 is in communication with the mud delivery pipe 8, and the main tank body 1 is fixedly provided with a descending pipe 9 connected to the inner end of the coil pipe 7, and the coil pipe 7 surrounds from the outside to the inside and The center of the upper end of the main tank body 1 is connected downwards with the descending pipe 9, the end of the descending pipe 9 opens toward the inner cavity, the opening end of the descending pipe 9 is provided with a trumpet-shaped outlet 13, and the filter suction end 2 is above the trumpet-shaped outlet 13, so A screw conveyor belt 10 is fixedly arranged in the mud delivery pipe 8 , a mud delivery pump 11 is arranged at the outer end of the screw conveyor belt 10 , and a mud discharge outlet 12 is provided at the lower end of the main tank.

With reference to shown in Figure 1, in order to make the work of mud-water separation tank more automatic, liquid level monitoring device 14 is provided with in the described inner cavity, and liquid level monitoring device 14 is above the filter suction end, and liquid level detecting device 14 is conveyed with described mud. The control device of the pump 11 is connected, and the control device is generally PLC, etc. When the liquid level of the mud in the inner cavity of the main tank 1 is lower than the critical liquid level of the liquid level monitoring device 14, the mud delivery pump 11 continues to work to transport the mud When the liquid level of the mud in the inner cavity is higher than or equal to the monitoring liquid level of the liquid level monitoring device 14, the mud delivery pump 11 stops working and no longer transports mud. Through the liquid level monitoring device 14, the injection of mud can be more targeted, which is beneficial to achieve a balance between the discharge of water and mud and the injection of mud, and is conducive to improving work efficiency.

The utility model also provides a method for separating mud and water by using a mud-water separation tank, including A, transporting the mud mixed with flocculant and lime to the screw conveyor belt 10 through the mud delivery pipe 8 and using the mud delivery pump 11, and the mud Flow slowly in the screw conveyor belt 10; B, mud is transported in the coiled pipe 7 by the mud conveying pipe 8, and the mud detours in the coiled pipe 7 until it reaches the trumpet-shaped outlet 13 of the downpipe 9 and is discharged into the main tank Body 1 cavity; C.
