Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a pre-filter demonstration device. Background Technology

[0002] In the existing pre-filter demonstration device, water flows in through the inlet of the pre-filter, is filtered by the pre-filter, and comes out through the outlet. The water only flows through the pre-filter.

[0003] The existing pre-filter demonstration devices have the following defects: First, the existing pre-filter demonstration devices cannot demonstrate the effect of filtering impurities in actual use scenarios; second, the pre-filter demonstration devices cannot demonstrate the effect of filtering impurities in actual use scenarios. Some pre-filter demonstration devices allow sand and impurities to be poured directly into the water tank, but the sand and gravel will damage the water pump after entering the water pump, causing the demonstration device to malfunction. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide a pre-filter demonstration device. This invention can demonstrate the effect of the pre-filter in filtering impurities in a real-world scenario, allowing users to visually and intuitively experience the filtering and sewage discharge effects of the pre-filter.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a pre-filter demonstration device, including a water tank, a water pump installed in the water tank, an inlet pipe connected to the water pump, a pre-filter connected to the inlet pipe, and an outlet pipe connected to the pre-filter. A three-way valve is installed on the inlet pipe, with one end connected to the inlet pipe, one end equipped with a sand-adding plug, and the other end connected to the pre-filter. The water pump has a water pump outlet, and a filter screen is installed between the inlet pipe and the water pump outlet. Through this technical solution, the sand-adding plug is opened to put particulate impurities into the inlet pipe, then the sand-adding plug is closed, and the water pump is started. The water pump draws water from the water tank. The filter screen between the inlet pipe and the water pump outlet prevents particulate impurities from entering the water pump through the inlet pipe and causing water pump malfunction. The water flow carries the particulate impurities into the pre-filter, and after filtration by the pre-filter, clean water is discharged from the outlet pipe, completing the pre-filter demonstration.

[0006] Preferably, the water pump is equipped with a water pump inlet, and the water pump inlet is equipped with an air suction pipe. When the water pump is working, due to the siphon effect, the air suction pipe draws in air, and the water coming out of the water pump outlet contains air bubbles. Because the water flow contains air bubbles, water droplets will be formed in the pre-filter, which will better demonstrate the sewage discharge effect.

[0007] Preferably, the water pump inlet is also equipped with an inlet filter. This filter prevents impurities from the water tank from entering the pump, which could cause it to seize up or be damaged.

[0008] Preferably, the water tank is equipped with a water pipe fixing bracket, which fixes the inlet pipe and the outlet pipe to the water tank respectively.

[0009] Preferably, a first short pipe is provided between the pre-filter and the three-way valve. The first short pipe is connected to both the three-way valve and the pre-filter. A copper nut is provided on the outside of the first short pipe to fix the first short pipe to the water inlet end of the pre-filter.

[0010] Preferably, an elbow is connected to the water outlet pipe, with one end of the elbow connected to the water outlet pipe and the other end connected to a second short pipe. The second short pipe is connected to the pre-filter, and a copper nut is provided on the outside of the second short pipe to fix the second short pipe to the water outlet end of the pre-filter.

[0011] Preferably, a ball valve is installed below the water outlet pipe. The ball valve can simulate the situation of water use at the end point during actual use.

[0012] Preferably, the water tank is divided into a clean water zone and a turbid water zone. The outlet pipe is located above the clean water zone, and the pre-filter has a drain outlet located above the turbid water zone. The water pump and inlet filtration device are located in the turbid water zone. The water tank is divided into two different areas: a clean water zone and a turbid water zone. Filtered clean water enters the clean water zone, and during wastewater discharge, water containing particulate impurities enters the turbid water zone, which can make the filtration effect more obvious.

[0013] As a preferred option, the water tank is equipped with a partition that divides the water tank into a clean water zone and a murky water zone.

[0014] Preferably, the water tank is equipped with a switch to turn the water pump on or off.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model can demonstrate the effect of a pre-filter in filtering impurities in a real-world scenario, allowing users to visually and intuitively experience the filtering and sewage discharge effects of the pre-filter.

[0017] 2. The water tank is divided into two different areas: a clean water area and a turbid water area. The filtered clean water enters the clean water area, and the water containing particulate impurities enters the turbid water area when the waste is discharged, which can make the filtration effect more obvious.

[0018] 3. The suction pipe is installed at the water pump inlet. It draws air in through siphon. Due to the siphon effect, the suction pipe draws in air, and the water coming out of the water pump outlet contains air bubbles. Because of the air bubbles in the water flow, water splashes will form inside the pre-filter, which better shows the sewage discharge effect. When used with a transparent pre-filter, rotating water splashes can be formed inside the filter bottle. The water flow state is displayed through the air bubbles, allowing customers to visually and intuitively feel the effect of the pre-filter in filtering and sewage discharge.
