For a clearer understanding of technical features, objects and effects of the present utility model, a detailed description of embodiments of the present utility model will be made with reference to the accompanying drawings.
As shown in fig. 1, an anti-clogging brine conveying apparatus according to an embodiment of the present utility model includes a brine tank 10, a brine pump 20, a thickener 30, a brine output pipe 40, and a brine return pipe 50.
Wherein, the inlet end of the salt slurry pump 20 is connected with the outlet of the salt precipitation tank 10, so that the salt slurry in the salt precipitation tank 10 is output under the power of the salt slurry pump 20. A salt slurry outlet pipe 40 is connected between the outlet end of the salt slurry pump 20 and the thickener 30 so that the salt slurry pumped by the salt slurry pump 20 is fed into the thickener 30 through the salt slurry outlet pipe 40. A salt slurry return pipe 50 is connected between the salt slurry output pipe 40 and the salt precipitation tank 10, and a salt slurry portion flowing along the salt slurry output pipe 40 can be returned into the salt precipitation tank 10 through the salt slurry return pipe 50.

In combination with the arrangement of the salt slurry reflux pipeline 50, under the power provided by the salt slurry pump 20, the salt slurry output pipeline 40 can be enabled to convey salt slurry with the flow rate larger than the target salt slurry, the requirement that the salt slurry flow rate in the salt slurry output pipeline 40 is larger than the flow rate of the salt slurry easy to block is met again, meanwhile, enough salt slurry with the flow rate meeting the target salt slurry enters the thickener 30, and the rest salt slurry can be returned into the salt precipitation tank 10 through the salt slurry reflux pipeline 50.

The flow meter 60 is used for detecting the flow rate of the salt slurry entering the thickener 30, and the control valve 70 controls the on-off state between the salt slurry output pipe 40 and the thickener 30. The flow rate of the salt slurry entering the thickener 30 (i.e., the target salt slurry flow rate) can be regulated by regulating the opening of the control valve 70, and the salt slurry flow rate is fed back to the flow meter 60, and meanwhile, the salt slurry flow rate in the salt slurry return pipeline 50 can be obtained by subtracting the salt slurry flow rate entering the thickener 30 according to the rated flow rate of the salt slurry pump 20, so that the salt slurry flow rate in the salt slurry return pipeline 50 is not lower than the easy-blocking salt slurry flow rate.

The anti-clogging salt slurry delivery device of the present utility model may further include a flush water pipe 100, a drain pipe 110, as needed.

After the brine pump 20 is started, brine enters the brine output pipe 40 and part of the brine enters the brine return pipe 50 through the brine output pipe 40; by combining the selection of the salt slurry pump 20, the salt slurry flow rates in the salt slurry output pipeline 40 and the salt slurry return pipeline 50 respectively reach 2.15m/s and 1.85m/s, and are not lower than the easy-to-block salt slurry flow rate (1.8 m/s). At the tail end of the salt slurry output pipe 40, due to the length of the pipe, the close proximity to the thickener 30 and the sufficient pipe diameter (DN 32), the salt slurry flows into the thickener 30 without risk of blockage while ensuring that the target salt slurry flow enters the thickener 30, and the rest of the salt slurry flows back into the salt precipitation tank 10 through the salt slurry return pipe 50 without risk of blockage.
