Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a sand removal mechanism of water purification equipment. Background Art

[0002] my country has a large area of ​​loess plateau and karst mountains, which causes many rivers to contain a lot of sediment, especially the high sediment content of the Yellow River, which is rare in the world. Most residents in northern my country use the Yellow River water for drinking and irrigation, but due to the high sediment content of the Yellow River water, it cannot be used directly by people, so corresponding water treatment plants are built in different regions to carry out a series of water treatment work on the sandy water.

[0003] The sand removal mechanism of the existing water purification equipment usually filters the raw water through a filter. The filtered sand cannot be discharged during the filtering process. The outer shell needs to be opened from time to time to process the sand filtered by the filter, which increases the labor burden of the staff and reduces the water purification efficiency. Utility Model Content

[0004] The utility model aims to provide a sand removal mechanism for water purification equipment, which has the characteristics of processing sediment during the filtering process and reducing the labor burden of the staff.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand removal mechanism of a water purification equipment, comprising a sand removal shell, a partition is fixedly connected to the interior of the sand removal shell, a through hole is penetrated through one side wall of the partition, a filter screen cylinder is rotatably connected to the right side wall of the partition, an outer tooth ring is fixedly connected to the outer wall of the filter screen cylinder, a sand receiving trough is fixedly connected to the interior of the through hole, one end of the sand receiving trough extends into the filter screen cylinder, a spray water pipe located above the filter screen cylinder is arranged inside the sand removal shell, one end of the spray water pipe extends to the lower end of the interior of the sand removal shell and is installed with a high-pressure water pump.

[0006] In order to drive the filter screen to rotate, as a preferred sand removal mechanism of a water purification device of the utility model, the right side wall of the partition is rotatably connected to a gear meshing with an external gear ring, and the left side wall of the partition is installed with a motor, and the output end of the motor is fixedly connected to the gear.

[0007] In order to facilitate the discharge of the mud and sand in the sand receiving trough, a sand removal mechanism of a water purification device of the utility model is preferably configured such that the other end of the sand receiving trough extends to the left side of the partition and is connected to a sand discharge pipe, and the other end of the sand discharge pipe extends to the outside of the sand removal shell.

[0008] In order to facilitate the flow of sediment in the sand receiving trough to the sand discharge pipe, as a preferred sand removal mechanism of a water purification device of the utility model, the inner lower end of the sand receiving trough is arranged as an inclined structure.

[0009] In order to fix the spraying water pipe, as a preferred sand removal mechanism of a water purification device of the utility model, a plurality of evenly distributed connecting rods are fixedly connected between the spraying water pipe and the sand removal housing.

[0010] In order to facilitate the discharge of filtered water from the sand removal housing, as a preferred sand removal mechanism of a water purification device of the utility model, the right end of the sand removal housing is connected to a drain pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The silt in the water is filtered through the filter cylinder, so that the filtered silt is adsorbed to the inner wall of the filter cylinder. The filter cylinder rotates, and the filter cylinder brings the filtered silt to the inner upper end of the filter cylinder. At the same time, the high-pressure water pump draws the water filtered by the filter cylinder into the spray water pipe, and the spray water pipe sprays water on the filter cylinder. The silt adsorbed on the inner wall of the filter cylinder is washed into the sand receiving trough by the high-pressure water to prevent the silt from clogging the filter cylinder. The silt is then discharged through the sand discharge pipe, and the silt is processed during the filtration process, avoiding the subsequent opening of the sand removal shell to clean the filter cylinder, thereby reducing the labor burden of the staff.
