Additionally, as shown in fig. 1 and 2, the glove box 701 is not a separate box but is located in the pretreatment tank 101 and is separated by a sealing partition 117, so that the overall simplicity is improved and the installation is convenient, and of course, another box may be separately provided for the glove box 701 as required.

Specifically, the rotating device comprises a rotating shaft 105 driven by a driving motor, the rotating shaft 105 is basically horizontally arranged, a ring-shaped rotating frame 106 is coaxially arranged on the rotating shaft 105, the fishing pocket 102 is arranged on the outer side of the ring-shaped rotating frame 106 along the radial direction of the rotating shaft 105, and the driving motor is electrically connected with the controller.

The ring-shaped rotating frame 106 herein refers to a ring-shaped structure composed of steel pipes, preferably a circular structure, such as one circular disc, or two circular discs with the same size, and the circular discs are fixed together by steel pipes and/or steel rods, and the fishing pockets 102 may be disposed on the ring-shaped rotating frame 106 in a manner that only one fishing pocket is disposed at any position of the ring-shaped rotating frame 106, or a plurality of fishing pockets 102 are disposed on the front side and the back side of the ring-shaped rotating frame 106, respectively.

Preferably, when the ring-shaped rotating frame 106 is provided with only one ring of the fishing pockets 102, the width of the fishing pocket 102 is substantially the same as the distance between the front and rear surfaces in the interior of the pretreatment tank 101, and when the ring-shaped rotating frame 106 is provided with two rings of the fishing pockets 102, the fishing pockets 102 having the width of the corresponding fishing pockets 102 combined on the two rings are increased, thereby increasing the fishing area.

As shown in fig. 3, 4 and 5, the fishing pocket 102 includes a first supporting frame 107, a second supporting frame 108 and a fishing net 109, and the first supporting frame 107 and the second supporting frame 108 are arranged at an included angle.

The included angle is between 0 and 180 degrees, and preferably, the included angle may be an obtuse angle to increase the fishing area of the fishing pocket 102.

The overshot 109 is disposed on the first support frame 107 and the second support frame 108, and may be fixedly disposed or detachably disposed (for example, clamped), and the size of the mesh of the overshot 109 may be specifically set according to the requirement.

As shown in fig. 2 and 4, the first support frame 107 is located on the opposite front side in the rotation direction generated when the rotation device rotates, the second support frame 108 is located on the opposite rear side, and the length of one side of the second support frame 108 in the rotation direction is greater than the length of one side of the first support frame 107 in the rotation direction, specifically, the length of one side of the second support frame 108 in the rotation direction is 1.1 to 2.5 times, preferably 2 times, the length of one side of the first support frame 107 in the rotation direction.

The length of one side of the second supporting frame 108 along the rotating direction is larger than that of one side of the first supporting frame 107 along the rotating direction, so that the fishing area is mainly increased, and the other side of the fishing pocket 102 along with the rotating device is mainly used for enabling opposite lower sides of the first supporting frame 107 and the second supporting frame 108 to contact with the liquid level at the same time as far as possible.

As shown in FIG. 6, additionally, in order to increase the pushing force of water against the fishing pocket 102 when the fishing pocket enters wastewater, which is opposite to the traveling direction of the fishing pocket, an outwardly extending pressing piece 118 is provided on the outer side of the second support frame 108, so that the pushing force of water against the fishing pocket 102 is increased by increasing the contact area of the second support frame 108 with water, thereby allowing the fishing pocket 102 in the water to be more spread to catch more suspended impurities in the wastewater.

Preferably, the pressing piece 118 is also provided in an arc shape, and the arc center of the arc shape is provided on the opposite front side in the rotation direction of the rotating device (i.e., the arc center of the pressing piece 118 is provided on the opposite front side in the rotation direction of the rotating device, and the pressing piece 118 is provided on the opposite rear side in the rotation direction).

As shown in fig. 6, in order to reduce resistance when the first support frame 107 and the second support frame 108 are filled with water, a conical head 119 is provided on the first support frame 107 and the second support frame 108 so as to be convex toward the front side in the rotation direction of the rotating device.

As shown in fig. 2 and 4, one side of the second support frame 108 in the rotation direction is disposed in an arc shape (preferably, a parabolic shape); one side of the first support frame 107 along the rotation direction is an arc-shaped arrangement, and the arc center of the arc is located at the outer side of the arc (i.e. the arc center is arranged at the opposite front side along the rotation direction of the rotation device, and one side of the first support frame 107 along the rotation direction is arranged at the opposite rear side along the rotation direction).

Preferably, the arc angle of the arc-shaped side of the first supporting frame 107 in the rotating direction is between 90 degrees and 150 degrees, and such an arrangement reduces the thrust of the first supporting frame 107 on entering the liquid surface, so as to reduce the occurrence of an event that the first supporting frame 107 rotates reversely as much as possible, thereby reducing the included angle between the first supporting frame 107 and the second supporting frame 108, and conversely, the arc angle of the arc-shaped side of the second supporting frame 108 in the rotating direction is between 30 degrees and 90 degrees, so that it is possible to realize reverse rotation of the second supporting frame 108 on entering the liquid surface by means of the thrust of the liquid surface, thereby being beneficial to increase the included angle between the first supporting frame 107 and the second supporting frame 108, and improving the fishing area.

One side of the second supporting frame 108 along the rotating direction is arranged in a parabola shape, so that sundries loaded in the fishing pocket 102 can be thrown towards the sundry inlet 103 along the rotating direction during throwing.

Example 2

The present embodiment is different from embodiment 1 in common in that: a hinge structure for enabling the first support frame 107 and the second support frame 108 to rotate relatively is arranged between the first support frame 107 and the second support frame 108, the hinge structure further comprises hinge holes 110 respectively formed in the first support frame 107 and the second support frame 108, and hinge shafts 111 are arranged in the hinge holes 110.

It should be noted that another main reason why the length of the second supporting frame 108 along one side of the rotation direction is greater than the length of the first supporting frame 107 along one side of the rotation direction is to enable the opposite lower sides of the first supporting frame 107 and the second supporting frame 108 to contact the liquid surface as simultaneously as possible when the fishing pocket 102 rotates along with the rotation device, so that the opposite lower sides of the first supporting frame 107 and the second supporting frame 108 receive an upward thrust simultaneously, and since the first supporting frame 107 and the second supporting frame 108 are hinged, after receiving the thrust, the first supporting frame 107 and the second supporting frame 108 rotate relatively to increase the degree of the included angle therebetween.

Additionally, the hinge structure further includes torsion springs provided between the first and

second support frames

107 and 108 and the hinge shaft 111.

The arrangement of the torsion spring can ensure that the first supporting frame 107 and the second supporting frame 108 in the fishing pocket 102 restore to the original included angle after leaving the liquid level, so that sundries in the first supporting frame 107 and the second supporting frame 108 can pass through the included angle after the fishing pocket 102 is exposed out of the water surface, and the sundries can be prevented from accidentally falling off from the sundries inlet 103 in the rotating process before being thrown to the sundries inlet.

Example 3

The present embodiment is different from embodiment 1 in common in that: the pretreatment tank 101 is internally provided with a high level liquid level device 112, the rotating shaft 105 and the high level liquid level device 112 are basically at the same height, the height of the opposite lower side of the sundries inlet 103 and the high level liquid level device 112 are basically at the same height, and the high level liquid level device 112 is electrically connected with the controller.

The purpose of locating the opposite lower sides of the rotating shaft 105, the high-level liquid level indicator 112 and the sundries inlet 103 at substantially the same height is to control the driving motor to drive the rotating shaft 105 by the controller when the high-level liquid level indicator 112 detects that the waste liquid level reaches the set height, so that the length of the contact surface of the rotating device and the waste water is as long as possible (i.e. the length is substantially the same as the diameter of the rotating device).

Additionally, in order to further increase the fishing area, the first and second support frames 107 and 108 on the fishing pocket 102 have substantially the same width as the interval between the front and rear sides inside the pretreatment tank 101.

Example 4

The present embodiment is different from embodiment 1 in common in that: in order to smoothly slide the part of the sundries thrown out of the fishing pocket 102, which does not enter the sundries inlet 103, into the waste water in the pretreatment tank 101 again, the side of the pretreatment tank 101 provided with the sundries inlet 103 is arranged in an inclined inward manner from top to bottom.

The working principle is as follows: preferably, when the high-level liquid level device 112 is installed, the driving motor is started only after the liquid level of the entering wastewater reaches the set position, the driving motor stops working for a set time, the water outlet 115 is opened at the moment, the filtered water with impurities removed enters the oil separating tank for further treatment, the water outlet 115 is closed again after the water is drained, and then the water inlet 114 is opened again, and the cycle is repeated.

If the rotation is stopped, the controller sends a message to start the driving motor, and when the ring-shaped rotating frame 106 rotates for a set time or a set number of times.
