Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
As shown in Fig. 1 ~ Fig. 6, the pollution discharge pump being convenient to safeguard in the present embodiment, includes housing 1, covers the top cover 2 on housing 1 and is arranged on pump motor 3, spiral case 4, impeller 5, cutter 6, float switch 8, the outlet pipe 7 in housing 1.
The main-vision surface of its middle shell 1 is provided with water inlet 11, this water inlet 11 uses as main water inlet, housing 1 is also provided with at least one auxiliary water inlet 12, when this pollution discharge pump is installed in different environments, facilitate connection in order to what adapt to site environment, auxiliary water inlet 12 can be used to carry out connection with sewage pipe.In the present embodiment, the both sides of housing 1 are respectively arranged with an auxiliary water inlet 12, to use as water inlet for subsequent use.
Pump motor 3 is vertically arranged in housing 1, the live axle of pump motor 3 stretches to the bottom direction of housing 1, the main body of pump motor 3 like this is in the middle and upper part of housing 1, decrease sewage to the immersion of pump motor 3 or eliminate the immersion of sewage to pump motor 3, greatly reduce the rate of fault of pump motor 3.
The upper end of pump motor 3 has one for the control circuit board of control pump motor 3 start and stop, and float switch 8 is connected electrically on the control circuit board of pump motor 3, and the bottom of float switch 8 extends the bottom near housing 1.Be arranged with a filter cap 9 outside float switch 8, filter cap 9 has multiple filtering hole.Can be filtered out the foreign material in sewage by filtering hole, prevent foreign material from snapping onto in float switch 8, then the sewage entered in filter cap 9 can not affect the normal work of float switch 8, and namely this filter cap 9 effectively can ensure the normal work of float switch 8.
Float switch 8 can fluctuate along with the wastewater level change sucked in housing 1 thus produce switching signal, after the switching signal of collection is sent to control circuit board by float switch 8, then can control the start and stop of pump motor 3, and then the automatic operation realizing pollution discharge pump controls.
Position top cover 2 corresponding to pump motor 3 in housing 1 is provided with access hole 21, and on access hole 21, matching cover has an access cover 211.When pump motor 3 needs to safeguard or keep in repair, then can open access cover 211, realize the maintenance to this motor by access hole 21, simple to operation.
Spiral case 4 in the present embodiment includes upper volute 41 and lower spiral case 42, forms a volute chamber between after upper volute 41 and the involutory connection of lower spiral case 42.This spiral case 4 is connected to the lower end of pump motor 3, and the live axle of pump motor 3 extend in volute chamber, and impeller 5 and cutter 6 are in transmission connection on the live axle of pump motor 3 from top to bottom successively, and namely impeller 5 is positioned at this volute chamber, and cutter 6 is positioned at the below of spiral case 4 bottom inlet.The bottom of lower spiral case 42 is provided with entrance 43 and is connected with the inside of housing 1, and the sidepiece of lower spiral case 42 is provided with outlet and is connected with outlet pipe 7.In the present embodiment, top cover 2 is provided with a water outlet 22, the end of outlet pipe 7 is communicated to this water outlet 22 and communicates with the external world, thus is discharged outside to from water outlet 22 by the sewage that pollution discharge pump sucks.
As shown in Figure 7, in the present embodiment, multiple blades 53 that impeller 5 comprises the rotating shaft 51 of a hollow, substrate 52 that radial direction is connected to rotating shaft 51 periphery and is arranged on substrate 52, multiple blade 53 is bent outwardly extension in divergent shape centered by described rotating shaft 51.
As shown in Figure 8, cutter 6 in the present embodiment comprises cutter body 61 and is distributed on three blades 62 of cutter body 61 periphery, the end of blade 62, thus makes to be more prone to the fibre object cutting sucked in sewage and discharge to impeller 5 direction inclination bending 25 ° relative to cutter body 61 place plane.
The using process of the pollution discharge pump in the present invention is as follows: extraneous sewage enters in housing 1 by water inlet 11 or auxiliary water inlet 12, along with the continuous injection of sewage, liquid level in housing 1 constantly raises, dirty buoyancy of water constantly increases, when the self gravitation of float switch 8 is less than sewage buoyancy, then float switch 8 constantly floats, when in housing 1, the liquid level of sewage reaches the upper limit level of float switch 8, float switch 8 is trigger action just, thus transmits electric motor starting signal in the control circuit board in pump motor 3.After receiving this electric motor starting signal in control circuit board, control pump motor 3 starts work, and then impeller 5 and cutter 6 rotate, impeller 5 and cutter 6 carry out cooperating thus are pulverized by the foreign material such as the fibrous object of sewage, and then the sewage after process in volute chamber is discharged from water outlet 22 by outlet pipe 7 by pump motor 3.
Pollution discharge pump carries out work continuously by said process until sewage level in housing 1 is lower than the bottom limit level of float switch 8.Namely when the bottom limit level of the sewage level in housing 1 lower than float switch 8, float switch 8 trigger action, thus transmit motor stop signal in control circuit board in pump motor 3.After receiving this motor stop signal in control circuit board, control pump motor 3 quits work.
Namely the automatic operation being achieved this pollution discharge pump by said process is controlled, and staff carries out manual operation without the need to constantly checking water level in housing 1, and it is more time saving and energy saving to use.
