DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0020] The present utility model provides a technical solution: As Figures 1 to 4 shown, in this embodiment, a wastewater treatment discharge device includes a water tank 1. A drainage channel 2 is provided at the bottom of the end of the water tank 1. A cleaning mechanism is provided above the water tank 1. The cleaning mechanism is composed of an intercepting plate 4 and a spiral conveyor blade 10. The intercepting plate 4 is suspended above the water tank 1. The intercepting plate 4 is connected to the water tank 1 through a lifting mechanism. A collection bin 5 is fixedly connected to the top end of the intercepting plate 4. A conveying pipe 9 is fixedly connected to the bottom of the collection bin 5. The side wall of the conveying pipe 9 is fixedly connected to the front side wall of the intercepting plate 4. A spiral conveyor blade 10 is arranged inside the conveying pipe 9. The top end of the spiral conveyor blade 10 penetrates through the collection bin 5 and is located inside the collection bin 5. A driving mechanism acting on the spiral conveyor blade 10 is connected to the collection bin 5.

[0021] Wherein, both sides of the intercepting plate 4 are inclined relative to the middle part thereof.

[0022] With such a setting, the wastewater floating substances intercepted by the intercepting plate 4 can gather towards the middle part of the intercepting plate 4.

[0023] Wherein, the driving mechanism is composed of a fixing plate 6 and a first motor 7. The fixing plate 6 is fixedly connected to the top end of the collection bin 5. The top end of the central axis of the spiral conveyor blade 10 is rotatably connected to the bottom of the fixing plate 6. A first motor 7 is fixedly connected to the upper end of the fixing plate 6. The output shaft of the first motor 7 is fixedly connected to the central axis of the spiral conveyor blade 10.

[0024] During use, when the first motor 7 is started, the spiral conveyor blade 10 can be driven to rotate.

[0025] Wherein, the inner cavity bottom of the collection bin 5 is inclined relative to the horizontal plane.

[0026] With such a setting, it is convenient to export the garbage in the collection bin 5 from the collection bin 5.

[0027] Among them, the lifting mechanism is composed of a mounting frame 3 and a guide block 8. The cross-section of the mounting frame 3 is an M-shaped structure. The two sides of the mounting frame 3 are fixedly connected to the two side walls of the water tank 1. The intercepting plate 4 is located at the front end of the mounting frame 3. A guide block 8 is fixedly connected to the side wall of the intercepting plate 4 close to the mounting frame 3. A guide groove 11 that slidably fits with the guide block 8 is provided on the mounting frame 3. The guide block 8 is connected to an adjusting mechanism. The adjusting mechanism is composed of a fixed top plate 12, a fixed bottom plate 13, a lead screw 14 and a second motor 15. The lead screw 14 passes through the guide block 8 and is connected to the guide block 8 through a threaded fit. The upper and lower ends of the lead screw 14 are respectively rotatably installed with a fixed top plate 12 and a fixed bottom plate 13. The fixed top plate 12 and the fixed bottom plate 13 are both fixedly connected to the side wall of the mounting frame 3. The upper end of the fixed top plate 12 is fixedly connected with a second motor 15. The output shaft of the second motor 15 is fixedly connected to the lead screw 14.

[0028] During use, start the second motor 15 to drive the lead screw 14 to rotate, thereby controlling the up and down movement of the guide block 8, and further controlling the height of the intercepting plate 4.

[0029] The utility model provides a discharge device for wastewater treatment, and the specific working principle is as follows:

[0030] During use, place the water tank 1 horizontally, then introduce sewage into the water tank 1, and introduce it into the next treatment process through the drainage channel 2. The speed of sewage introduction should be balanced with the sewage discharge speed to ensure that the water surface height in the water tank 1 fluctuates within a very small range. Control the bottom of the intercepting plate 4 to be immersed in water (but not in contact with the bottom of the water tank 1) through the lifting mechanism. At this time, the intercepting plate 4 will intercept the floating objects on the wastewater. Since the two sides of the intercepting plate 4 are inclined, the intercepted floating objects will gather towards the middle of the intercepting plate 4. At this time, energize the first motor 7 to drive the spiral conveying blade 10 to rotate. The spiral conveying blade 10 will convey the floating objects on the water surface upwards into the collection bin 5. A collection frame for collecting garbage can be arranged at the side end opening position of the collection bin 5, so as to quickly and effectively complete the cleaning of the floating objects in the wastewater, and this cleaning method will not cause the problem of filter screen blockage, and can continuously clean the floating objects in the wastewater, which can effectively improve the wastewater treatment efficiency.

[0031] It should be noted that the length of the water tank 1 in the figure is not the specific length. In actual application, the length of the water tank 1 needs to be long enough to ensure that the water surface near the intercepting plate 4 is stable, and to avoid the wastewater hitting the water surface when entering the water tank 1, resulting in the water surface fluctuating, and further resulting in the intercepting plate 4 not being able to intercept the floating objects well.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
