[0065] It is found through research that in the prior art, the sludge discharge device for sewage treatment cannot well discharge the sludge in the sewage tank, and the sludge discharge effect is poor. For example, in the authorized patent with the application number CN202321122898.0, a vertical auger is adopted to extract the sludge in the sewage tank by rotating the auger. In the actual scene of sewage treatment, the sludge in the sewage tank presents a very loose physical state. This feature makes the conventional vertical auger face severe challenges in performing the extraction work, and it is difficult to effectively extract the sludge from the sewage tank, which has certain limitations in sludge treatment.

[0066] Based on the above research, the present disclosure provides a sewage discharge device and a sewage treatment device. The sewage discharge device is placed horizontally by a spiral conveying shaft, and a scraping member is used in cooperation with the spiral conveying shaft. The loose sludge deposited at the bottom of the sedimentation tank is pushed by the scraping member to the spiral conveying shaft. The loose sludge is discharged by the horizontally arranged spiral conveying shaft, effectively solving the technical problem of inconvenient extraction of loose sludge.

[0067] The defects of the above solutions are the results of the inventors after practice and careful research, therefore, the discovery process of the above problems and the solutions proposed by the present disclosure to solve the above problems should be the contributions of the inventors to the present disclosure in the process of the present disclosure.

[0068] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0069] Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.

[0070] In some embodiments, as Figure 1As shown, before starting the sewage treatment operation, the operator starts the air pump 120, and the compressed air is introduced into the aeration pipe 122 through the pump air pipe 121, and is discharged from the air outlet fixed on the aeration pipe 122 to aerate the sewage in the aerobic tank 10. The air pump 120 is used instead of the air blower in the prior art, which can better control the dissolved oxygen in the aerobic tank, and after the aeration is completed, the transmission pump 16 is started, and the treated sewage in the aerobic tank 10 is introduced into the sedimentation tank 11 through the sewage pipe 15 for sedimentation.

[0071] In some embodiments, as Figure 2 As shown, when the treated sewage enters the sedimentation tank 11 and is completely deposited, the driving motor 170 is started, and the output end drives the helical conveying shaft 131 to rotate in the positive direction, and simultaneously drives the screw rod 171 to rotate through the transmission belt 171, and the screw rod 171 drives the T-shaped moving piece 141 connected therewith to move. At this time, the scraping piece 140 is driven to slide along the bottom surface of the sedimentation tank 11. As shown in the figure, the end surface of the scraping piece 140 towards the helical conveying shaft 131 is inclined, so that the sludge deposited on the bottom surface of the sedimentation tank 11 is pushed into the helical conveying shaft 131 with the movement of the scraping piece 140, and the sludge is discharged with the rotation of the helical conveying shaft 131.

[0072] When the driving motor 170 is started and the output end is reversely rotated, at this time, since the helical conveying shaft 131 and the output end of the driving motor 170 are provided with one-way bearings, the helical conveying shaft 131 is stationary, and the driving motor 170 drives the transmission belt 171 and the screw rod 142 to reverse, thereby driving the T-shaped moving piece and the scraping piece 140 to reset for the next sludge removal operation.

[0073] In the description of the embodiments of the utility model, unless there is definite provision and limitation, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium, it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0074] In the description of the utility model, it is necessary to explain, the term "center", "upper", "lower", "left", "right", "vertical", "horizontal", "internal", "external" and so on indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model. In addition, terms such as "first", "second" and other numerical terms are used in this text, and do not imply order or sequence unless the text is explicitly indicated. Therefore, the first element, component, area, layer or section discussed above can be referred to as the second element, component, area, layer or section without departing from the teachings of the example embodiments.

[0075] Spatially relative terms, such as "internal", "external", "lower", "under", "bottom", "top", "above", and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms can be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0076] In the above discussion, unless otherwise stated, the terms "about", "approximately", "substantially" and the like, when used in describing a numerical value, mean a variation of + / - 10% of the value.

[0077] With the above ideal embodiments according to the utility model as the inspiration, through the above description, relevant staff can definitely make various changes and modifications without deviating from the technical thought of the utility model. The technical scope of the utility model is not limited to the content in the specification, and must be determined according to the scope of claims.
