Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

Fig. 1 shows a schematic structural view of an impurity removing apparatus 100 according to an embodiment of the present application. The impurity removal device 100 may be an air flotation tank residue scraper, and in the following description of the present application, the impurity removal device 100 is exemplified as an air flotation tank residue scraper. Of course, those skilled in the art will appreciate that the impurity removal apparatus 100 may also be other apparatuses for removing impurities, and is not limited to the floatation tank residue scraper.

As shown in fig. 1, the impurity removing apparatus 100 includes a bracket 110, a rotation shaft 120, and a scraper 130. Wherein, both ends of the rotating shaft 120 are pivotally connected with the bracket 110, the scraper 130 is fixed on the rotating shaft 120, and under the condition that the rotating shaft 120 rotates, the scraper 130 is driven by the rotating shaft 120 to rotate around the central axis of the rotating shaft 120, so as to discharge the impurities 200 to be discharged.

For example, both ends of the rotating shaft 120 may be respectively mounted on the bracket 110 through bearings, thereby achieving relative rotation between the rotating shaft 120 and the bracket 110. The scraper 130 may be directly fixed to the outer circumferential surface of the rotary shaft 120, and the rotary shaft 120 may be disposed at the outlet of the impurities 200 to be discharged, such as the air-float pool oil residue. When the rotating shaft 120 rotates around its central axis, the rotating shaft 120 drives the scraper 130 to rotate along the central axis of the rotating shaft 120, so that the impurities 200 to be discharged are discharged from the outlet by the scraper 130, thereby achieving the purpose of sewage purification.

According to impurity removal equipment 100 of the embodiment of this application, for example, sediment scraper in air flotation tank, through making scraper 130 be fixed in rotation axis 120, compare with the mode that the scraper was installed in the chain among the prior art, reciprocating chain can be saved to can avoid producing the trouble that the chain broke and the chain derailed, effectively reduce impurity removal equipment 100 for example the fault rate of sediment scraper in air flotation tank, reduce installation and maintenance cost, guarantee impurity removal equipment 100 for example the normal operating of sediment scraper in air flotation tank, and then promote impurity removal equipment 100 for example the operating rate of sediment scraper in air flotation tank when energy saving and consumption reduction.

In one embodiment, the scraper 130 includes a mounting portion and a slag scraping portion. Wherein, inject the mounting hole that link up along the axial of rotation axis 120 in the installation department, rotation axis 120 fixed fit is in the mounting hole, scrapes the sediment portion and connects in the installation department, scrapes the axial that the sediment portion is on a parallel with rotation axis 120 to will wait to discharge impurity 200 under the drive of rotation axis 120.

For example, the mounting portion may be formed in a substantially circular ring shape, and the mounting portion is sleeved on the rotating shaft 120 and is fixedly connected with the rotating shaft 120. The slag scraping part may be formed in a substantially plate-like structure, i.e., the length and width of the slag scraping part are much greater than the thickness of the slag scraping part, one side of the slag scraping part may be connected to the mounting part, and the other side of the slag scraping part may extend toward a side away from the rotating shaft 120. The surface of the slag scraping part may contact with the impurities 200 to be discharged, such as the oil residue of the air flotation tank, and the slag scraping part may scrape the impurities 200 to be discharged from the outlet in the case that the rotation shaft 120 rotates.

In one embodiment, referring to fig. 1 and 2, both ends of the scraper 130 extend to adjacent both ends of the rotary shaft 120, respectively. For example, in the example of fig. 1 and 2, one end of the scraper 130 extends to one end adjacent to the rotary shaft 120 and the other end of the scraper 130 extends to the other end adjacent to the rotary shaft 120 in the central axis direction of the rotary shaft 120. That is, the distance between the end of the scraper 130 and the corresponding end of the rotary shaft 120 is smaller than the distance between the end of the scraper 130 and the axial middle position of the rotary shaft 120. So set up, scraper blade 130's length is longer to can enlarge scraper blade 130 and wait to arrange the contact range between the miscellaneous material 200, make scraper blade 130 can effectively discharge waiting to arrange miscellaneous material 200, under the circumstances that impurity removal equipment 100 scraped the sediment machine for the air supporting pond, can effectively discharge dross and debris in the air supporting pond, promote sewage treatment effect.

Therefore, t is more than or equal to 5mm and less than or equal to 15mm, so that the scraper 130 has high structural strength, the scraper 130 is prevented from being deformed or damaged in the operation process, the operation efficiency of the rotating shaft 120 can be improved, and the cost of the whole impurity removing equipment 100, such as a residue scraping machine of an air flotation tank, is reduced.

In an alternative embodiment, the diameter of the rotating shaft 120 is D, wherein D is 60mm ≦ 110 mm. Specifically, for example, when D < 60mm, the diameter of the rotary shaft 120 is too small, the load-bearing capacity is poor, and deformation or breakage is easily generated; when D > 110mm, the diameter of the rotary shaft 120 is excessively large, resulting in an excessively heavy weight and high cost of the rotary shaft 120. Therefore, D is larger than or equal to 60mm and smaller than or equal to 110mm, the diameter of the rotating shaft 120 is reasonable, and the rotating shaft 120 has high mechanical property, so that the cover plate is driven to effectively discharge the impurities 200 to be discharged, the whole impurity removing equipment 100 such as an air flotation tank residue scraping machine has high structural stability and reliability, and the service life of the impurity removing equipment 100 such as the air flotation tank residue scraping machine is prolonged.

It is understood that the fixing manner of the scraper 130 and the rotating shaft 120 can be specifically determined according to actual requirements to better meet the actual application.

In an alternative embodiment, the rotating shaft 120 may be a stainless steel shaft. With such an arrangement, the rotating shaft 120 has high corrosion resistance, so that the rotating shaft 120 can be effectively prevented from being corroded in a severe environment, the service life of the rotating shaft 120 can be prolonged, and the reliability of the impurity removing apparatus 100, such as an air flotation tank residue scraper, can be improved.

In an alternative embodiment, the impurity removing apparatus 100 further comprises a transmission member 170 in transmission connection with the driving member 150 and the driven member 160, respectively. Therefore, the transmission member 170 can effectively transmit the driving force of the driving assembly to the rotating shaft 120 when the driving member 150 and the driven member 160 are far away from each other, so that the driving assembly and the rotating shaft 120 can more flexibly select the installation space while the automatic rotation of the rotating shaft 120 is realized, and the installation difficulty of the driving assembly and the rotating shaft 120 is effectively reduced.

Of course, the present application is not limited thereto, and in another alternative embodiment, the driving member 150 and the driven member 160 may also be directly engaged, so that the driving force of the driving assembly may also be effectively transmitted to the rotating shaft 120, and the structure is more compact, and the occupied space may be reduced. It is understood that the driving member 150 and the driven member 160 may be connected in a transmission manner according to actual requirements.
