Description

Technical Field

[0001] The present invention relates to the technical field of water supply equipment, and specifically relates to a constant pressure variable frequency water supply unit. Background Art

[0002] Secondary water supply equipment is generally installed on the ground or in the basement. For units with tap water, this equipment can be used to dispatch peak water consumption and increase water pressure, and can meet the large-area water use and high-rise building water use during peak water use. For units, factories or villages without tap water, only by connecting this equipment to the water source power supply, a stable water volume and water pressure can be obtained to meet the water use needs. The secondary water supply equipment consists of three parts: a pressure tank, a water pump and an electric control system. Its outstanding advantages are that there is no need to build a water tower, with small investment, less land occupation, flexible installation, quick construction and commissioning. It adopts automatic air-water regulation, automatic operation, energy saving and automatic grid connection with tap water, and can still supply water after a power outage. It does not need to be monitored after commissioning, and is widely used in production and daily water supply.

[0003] The secondary water supply equipment uses pneumatic water supply and uses a sealed tank body. The high-pressure gas-water pressure in the tank is used to achieve the purpose of water supply. Therefore, during the secondary water supply process, when air is introduced through the air inlet pipe, it is necessary to filter the gas. The filter in the traditional air inlet pipe is basically of a fixed cycle, that is, while filtering, impurities will also accumulate on the filter synchronously until the filtering effect is seriously affected. At this time, one use cycle ends, and it needs to be replaced and cleaned, which is rather troublesome. For this reason, we propose a constant pressure variable frequency water supply unit.

A fifth gear disk (74) is provided at one end of the shaft three (73). A sixth gear disk (75) that meshes with the fifth gear disk (74) is provided at one end of the shaft two (56). The shaft two (56) is rotated to drive the rotating column (69) to rotate.

6. A constant-pressure variable-frequency water supply unit according to claim 5, characterized in that: The sixth gear disk (75) is designed with a diameter smaller than that of the fifth gear disk (74).

7. A constant-pressure variable-frequency water supply unit according to claim 6, characterized in that: A collection box (92) is provided on the intake pipe (1). Ash collection boxes (76) are provided at both ends of the baffle (6). A linkage assembly (77) is provided on the baffle (6). In the initial state of the ash collection box (76), it is perpendicular to the baffle (6) to receive dust. The baffle (6) is rotated so that its end reaches the collection box (92). The baffle (6) is further rotated and the linkage assembly (77) is used to drive the ash collection box (76) to deflect and pour dust into the collection box (92).

8. A constant pressure variable frequency water supply unit according to claim 7, characterized in that: the linkage assembly (77) includes a shaft six (78) arranged at one end of the ash collecting box (76), the shaft six (78) is connected to the baffle plate (6), a turbine (79) is arranged on the shaft six (78), a shaft seven (81) is arranged on the baffle plate (6), one end of the shaft seven (81) is provided with a worm (82) meshing with the turbine (79), and a torsion spring (83) is arranged on the shaft seven (81). In the initial state of the torsion spring (83), the ash collecting box (76) is perpendicular to the baffle plate (6). Rotating the shaft seven (81) drives the ash collecting box (76) to deflect, and at the same time the torsion spring (83) is stressed and twisted to provide a self-returning ability for the ash collecting box (76); one end of the shaft seven (81) is provided with a gear disc seven (84), an arc-shaped body (85) is arranged on the mounting frame two (87), and a plurality of tooth grooves (86) are evenly formed at equal intervals on the arc-shaped body (85). Rotating the deflection plate drives the gear disc seven (84) to engage with the tooth grooves (86) and roll along them, so that the shaft seven (81) rotates.
