Further, threaded connector is bolt, and axial blind hole is opened in the end of thread of bolt, and radially the axial distance of a side of the close spout hole of the nut of the peritreme of spout hole and bolt is 3mm ~ 8mm.
Further, threaded connector is bolt, and overflow part also comprises the gasket seal between the nut of radially spout hole and bolt be arranged on bolt.
Further, tank also comprises water inlet.
Further, water inlet is arranged on the sidewall relative with overflow part.
Further, overflow part comprise two above overfalls and with these two above overfalls two above water level control parts one to one.
Further, two above overfalls are arranged at the differing heights place of tank side.
Further, two above overfalls layout that misplaces in the horizontal direction.
Apply precleaning unit of the present utility model, toward constantly injecting clean water in tank, overflow part is set on tank and maintains the tank water level, effluent sewerage and assist draining maintenance water level constant by discharge outlet when discharge outlet being set tank clear up simultaneously.Due to the clean water of constantly the injecting whole tank of flowing through, and sewage is discharged from overflow part and/or discharge outlet, therefore, can keep the water cleaning in tank, maintain the tank water level simultaneously and realize the adjustable purpose of water level.Due to water cleaning, can guarantee cleaning quality.Further, this precleaning unit does not need the employee to change specially water, can promote operating efficiency.
The accompanying drawing explanation
The Figure of description that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of water tank device of the present utility model;
Fig. 2 shows the A of Fig. 1 to structural representation.
The specific embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, the present embodiment provides a kind of precleaning unit.Precleaning unit comprises tank 1, support portion 2 and inserted sheet platform 3.Tank 1 comprises water inlet 11, discharge outlet 12 and overflow part 13.Wherein, water inlet 11 is arranged on tank 1 sidewall relative with overflow part 13.In the present embodiment, tank 1 is in particular long 1m, wide 1m, and the cuboid of dark 30cm, material is the stainless steel that 3mm is thick.Support portion 2 is for supporting tank 1.Water inlet 11 is arranged on tank 1 front end, and the water sources such as water inlet 11 and running water pipe are connected, and are used to tank 1 that water source is provided.But in an embodiment who does not provide, water inlet 11 also can be cancelled, by such as water sources such as running water pipes, directly for tank, providing current.Discharge outlet 12 is arranged at tank 1 bottom, at water inlet 11 flow of inlet water, when larger, for auxiliary draining, keeps water level constant.Effluent sewerage when discharge outlet 12 also can be used to tank 1 cleaning.
Above precleaning unit is provided with the position water inlet 11 relative with overflow part 13 on tank 1 can constantly inject clean water, overflow part 13 is set simultaneously and maintains tank 1 water level, effluent sewerage and keep water level constant for auxiliary draining when being provided with discharge outlet 12 and being used for to tank 1 cleaning., through tank 1 sewage is discharged from overflow part 13 and/or discharge outlet 12 due to the current that enter tank 1 inside by water inlet 11, therefore, can keep the water cleaning in tank 1, the water level that simultaneously maintains tank 1 realizes that water level can regulate.Due to water cleaning, can guarantee cleaning quality.Further, this precleaning unit does not need the employee to change specially water, can promote operating efficiency.
As depicted in figs. 1 and 2, overflow part 13 comprises the position that is arranged at tank 1 side higher than the overfall 131 of discharge outlet and selectively opens or the water level control part 132 of shutoff overfall 131.
Water level control part 132 comprises threaded connector.Threaded connector comprises the radially spout hole of opening on the axial blind hole of an end that screws in overfall 131 and the thread segment that is opened in threaded connector that is communicated with axial blind hole.Overfall 131 is provided with the internal thread coordinated with the thread segment of threaded connector.
In the present embodiment, threaded connector is in particular bolt.Axial blind hole is opened in the end of thread of bolt, and radially the close radially axial distance of a side of spout hole of the nut of the peritreme of spout hole and bolt is 3mm ~ 8mm place, is preferably the 5mm place and is communicated with axial blind hole.Radially the shape of spout hole can be for square or circular etc.
As depicted in figs. 1 and 2, tank 1 comprise two above overfalls 131 and with these two above overfalls 131 two above water level control parts 132 one to one.Two above overfalls 131 are arranged at the differing heights place of tank 1 side.Two above overfalls 131 layout that misplaces in the horizontal direction.
In the present embodiment, overflow part 13 comprises top-down three overfalls 131 that are arranged on tank 1 rear end.Three overfalls 131 specifically comprise highstand shedding mouth, middle water level overfall and low water level overfall.And three overfalls 131 are arranged in tank 1 side along continuous straight runs dislocation.Overflow part 13 also comprise and three overfalls 131 one to one, and each overfall 131 respectively threaded engagement three bolts and be arranged on each bolt, at the gasket seal between spout hole and nut radially.
While needing to reduce the water level of tank 1, selection unscrews the bolt of the overfall corresponding with required water level 131, expose the radially spout hole on bolt, the water in tank 1 will, by the axial blind hole of bolt and radially spout hole outflow, be realized the function of the water level of reduction tank 1.While needing to promote the water level of tank 1, the bolt of restraint zone gasket seal, the shutoff overfall 131 corresponding with bolt leaks in order to prevent.
