[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1:

[0022] See also Figure 1-2 A small-scale domestic sewage integrated treatment device comprises a box body 1, in which a filter plate 2 is fixed in an inclined and detachable manner, a shell body 5 is fixed on the box body 1 corresponding to the filter plate 2, the filter plate 2 is inclined toward the shell body 5, a cylinder body 7 is fixed on the shell body 5 along its axis direction, and the shell body 5 and the cylinder body 7 are distributed in sequence from top to bottom, a groove 11 is provided on the inner wall of the cylinder body 7, a connecting block 12 is rotatably connected in the groove 11, a filter cartridge 6 located in the groove 11 is arranged in the connecting block 12, a plurality of tooth grooves 13 are provided on the outer periphery of the connecting block 12, a motor is fixed on the shell body 5, a gear 14 is fixed on the outer side of the motor output shaft, a connecting port 10 is provided on the cylinder body 7 corresponding to the gear 14, the connecting port 10 is connected to the groove 11, and the gear 14 is meshed with the tooth groove 13 through the connecting port 10.

[0023] In actual use, domestic sewage is injected into the housing 1, and the domestic sewage will first be filtered by the filter plate 2, and the mixed sewage will remain stationary in the housing 1 to wait for treatment. After the filter plate 2 filters the domestic sewage, the impurities in the domestic sewage will be introduced into the middle shell 5 by the filter plate 2, and the shell 5 will send the impurities into the drum. At this time, the driving member 9 drives the gear 14 to rotate. With the cooperation of the gear 14 and the tooth groove 13, the connecting block 12 can rotate in the groove 11, and the filter cartridge 6 will also rotate accordingly. Under the action of the centrifugal force generated by the rotation of the filter cartridge 6, the debris in the filter cartridge 6 can be thrown out with oil and water attached to the debris, so that they are collected by the cylinder 7 for subsequent treatment.

[0024] Embodiment 2:

[0025] The basic content is the same as that of Example 1, except that:

[0026] See also Figure 2 In this embodiment, the cylinder 7 is connected with a connecting pipe 8, and the connecting pipe 8 is connected with the box body 1.

[0027] After the rotating filter cartridge 6 peels off the oil and water from the debris by centrifugal force, the oil and water will fall into the cylinder body 7. At this time, the oil and water will be introduced into the mixture in the box body 1 under the action of the connecting pipe 8, and will be still together for subsequent processing.

[0028] Embodiment 3:

[0029] The basic content is the same as that of Example 1, except that:

[0030] See also Figure 2-3 In this embodiment, a mounting opening is provided on the shell 5, a door body is hinged on the shell 5 by a hinge, the filter cartridge 6 is detachably fixed in the connecting block 12, the cylinder body 7 is detachably fixed on the shell 5, a plurality of tooth grooves 13 are evenly spaced on the periphery of the connecting block 12, and an oleophobic layer is provided on the cylinder body 7, the rotating drum and the shell 5.

[0031] When the oil and water are stripped from the debris by centrifugal force, the oil and water will be temporarily stored in the cylinder 7. At this time, the filter cartridge 6 can be removed from the connecting block 12 through the door on the shell 5, so that the filter cartridge 6 can be removed from the cylinder 7 to facilitate subsequent treatment of the debris in the filter cartridge 6. At the same time, when treating the oil and water stored in the cylinder 7, the cylinder 7 is separated from the shell 5, which can facilitate the treatment of the oil and water stored in the cylinder 7, and under the action of the oleophobic layer, there is no need for residue.

[0032] Furthermore, the cylinder 7 performs linear motion along the width direction of the shell 5 .

[0033] Specifically, after the cylinder 7 is moved along the width direction of the shell 5 to be completely separated, the cylinder 7 is separated from the shell 5. At this time, the gear 14 will also be moved out from the tooth groove 13 and the connecting port 10. After the cylinder 7 is reinstalled, the outer side of the gear 14 will penetrate and extend to the inside of the connecting port 10 and engage with the tooth groove 13.

[0034] Embodiment 4:

[0035] The basic content is the same as that of Example 1, except that:

[0036] See also Figure 2 In this embodiment, a first opening 3 is opened on the box body 1 corresponding to the filter plate 2, and a second opening 4 is opened on the shell body 5 corresponding to the first opening 3. The box body 1 and the shell body 5 are connected through the first opening 3 and the second opening 4, and the width of the first opening 3 and the second opening 4 is equal to the width of the filter plate 2.

[0037] After the debris is separated from the mixed sewage, the debris will remain on the filter plate 2, and under the action of the inclined filter plate 2, the debris can be effectively sent into the shell 5. At the same time, under the action of the first opening 3 and the second opening 4 which are equal in width to the filter plate 2, the debris can be prevented from remaining in the dead corners.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
