DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 4 As shown, the present invention proposes a sewage treatment machine, comprising: a treatment box 1, a treatment chamber is provided in the treatment box 1, three partitions are installed on the inner wall of the treatment chamber, the three partitions divide the treatment chamber into an anaerobic zone 11, an aerobic zone 12, a sedimentation zone 13 and a disinfection zone 14 from left to right, the top of the anaerobic zone 11 is connected with the top of the aerobic zone 12, the bottom of the aerobic zone 12 is connected with the bottom of the sedimentation zone 13, the top of the sedimentation zone 13 is connected with the top of the disinfection zone 14, four connecting pipes 15 are installed on the top of the treatment box 1, each connecting pipe 15 is connected with the anaerobic zone 11, the aerobic zone 12, the sedimentation zone 13 and the disinfection zone 14 respectively, each connecting pipe 15 is opened and closed by a pipe cover 16, an inlet pipe 3 is installed on the pipe cover 16 located above the anaerobic zone 11, a filter device 2 is installed next to the inlet pipe 3, the filter device 2 is used to remove particulate impurities in the influent, and an outlet pipe 4 is installed on the side wall of the treatment box 1, and the outlet pipe 4 is connected with the disinfection zone 14.

[0021] In order to design a filter device 2 with a simple structure, the filter device 2 includes: a mounting cylinder 21 and a filter screen 22. The mounting cylinder 21 is mounted on the inner wall of the pipe cover 16 on which the water inlet pipe 3 is mounted. The mounting cylinder 21 is connected to the water inlet pipe 3 and extends toward the anaerobic zone 11. The mounting cylinder 21 is mounted with a filter screen 22.

[0022] In order to facilitate the cleaning of the filter screen 22 and to facilitate the discharge of impurities from the mounting cylinder 21 after the filter screen 22 is opened, at least two protrusions 23 are protruding from the top edge of the filter screen 22, and the bottom surface of the mounting cylinder 21 is recessed to form a vertical guide groove 210. The vertical guide groove 210 is used to guide the protrusion 23 to move in the vertical direction relative to the mounting cylinder 21. The inner wall of the mounting cylinder 21 is recessed to form a horizontal guide groove and a mounting groove 211. The horizontal guide groove connects the top of the vertical guide groove 210 with the mounting groove 211. The horizontal guide groove is used to guide the protrusion 23 to rotate relative to the mounting cylinder 21. The inner wall of the mounting groove 211 and the inner wall of the horizontal guide groove are used to limit the protrusion 23 from detaching from the mounting cylinder 21 in the vertical direction.

[0023] In order to conveniently remind the operator to discharge the particulate impurities in the installation tube 21 in time, an elastic indicator device 25 is installed in the installation groove 211. The elastic indicator device 25 acts on the protrusion 23. The indicating part of the elastic indicator device 25 emerges from the top surface of the tube cover 16. The elastic indicator device 25 is used to indicate that the particulate impurities on the filter screen 22 are overweight.

[0024] In order to prevent the protrusion 23 from entering the vertical guide groove 210 through the horizontal guide groove and causing the filter 22 to fall to the bottom of the anaerobic zone 11 due to water impact during use, an elastic stopper 26 is installed on the installation cylinder 21. The elastic stopper 26 is used to limit the protrusion 23 located in the installation groove 211 from sliding into the horizontal guide groove. During use, due to water impact and other reasons, it is very likely that the filter 22 rotates in the installation cylinder 21. After the filter 22 rotates, the protrusion 23 is separated from the installation cylinder 21 through the horizontal guide groove and the vertical guide groove 210 and falls to the bottom of the anaerobic zone 11, resulting in the inability to realize the basic function of the filter 22, and a large amount of particulate impurities enter the treatment box 1 and are difficult to be discharged. By setting an elastic limiting device 26, an elastic member is arranged inside the elastic limiting device 26, and the elastic member keeps the elastic limiting device 26 in a state of limiting the protrusion 23 located in the installation groove 211 from sliding into the horizontal guide groove. Adjusting the elastic limiting device 26 can allow the protrusion 23 to enter the installation groove 211 from the vertical guide groove 210 through the horizontal guide groove during installation, thereby ensuring that the installation of the protrusion 23 can be realized and limiting the protrusion 23 from being separated from the installation tube 21 at will.

[0025] In order to ensure that the elastic limiting device 26 is always kept in a state of limiting the protrusion 23 in the installation groove 211 from sliding into the horizontal guide groove during use, the elastic limiting device 26 is provided with a positioning portion, which is used to be clamped between the pipe cover 16 and the connecting pipe 15. The positioning portion is used to keep the elastic limiting device 26 in a state of limiting the protrusion 23 in the installation groove 211 from sliding into the horizontal guide groove when being clamped between the pipe cover 16 and the connecting pipe 15. The elastic member has tolerance, and vibration and other reasons may cause the elastic limiting device 26 to jump and release the protrusion 23. In order to avoid this possibility, the positioning portion of the elastic limiting device 26 is designed to be clamped between the pipe cover 16 and the connecting pipe 15.

[0026] A guide plate 24 extending into the mounting tube 21 is connected to the inner wall of the pipe cover 16 . The guide plate 24 is tilted downward after being connected to the pipe cover 16 . The angle between the guide plate 24 and the horizontal direction is an acute angle. The guide plate 24 is located directly below the water inlet pipe 3 .

[0027] The pipe cover 16 is detachably connected to the connecting pipe 15 by screws.

[0028] The design ideas of this embodiment are as follows: first, in order to prevent a large amount of particulate impurities from entering the treatment box 1, a filter device 2 is designed at the water inlet pipe 3 to filter the particulate impurities at the filter device 2; then, the water is discharged from the water inlet pipe 3 and passes through the filter screen 22 of the filter device 2 under its own gravity; then, in order to facilitate the cleaning of the filter screen 22, the particulate impurities in the installation cylinder 21 can be discharged by opening the filter screen 22 at the same time, so the filter screen 22 is designed to be detachably connected to the installation cylinder 21, so that the impurity discharge function and the filter screen 22 cleaning function can be realized by opening the filter screen 22; then, due to When water is discharged from the water inlet pipe 3, the water exerts an impact force on the filter screen 22 in the vertical direction. Therefore, in order to ensure the reliability of the connection between the filter screen 22 and the installation cylinder 21, the protrusion 23 is screwed in by rotation, and the installation cylinder 21 has a supporting force on the protrusion 23 in the vertical direction, thereby avoiding the protrusion 23 from being separated from the installation cylinder 21 due to excessive impact force; then, in order to conveniently observe whether the impurities on the filter screen 22 are too heavy and to promptly remind the operator to discharge the impurities in the installation cylinder 21, an elastic indicator device 25 is designed; then, because the elastic indicator device 25 is to be observed when the water inlet pipe 3 is opened, but due to At this time, the impact force of the water inlet pipe 3 on the filter screen 22 is relatively large. The filter screen 22 is subjected to not only the gravity of the impurities but also the impact force of the water in the vertical direction, which can easily cause the elastic indicator device 25 to indicate that the vertical force on the filter screen 22 is too large, prompting the operator to discharge the impurities in the installation cylinder 21 in time, thereby realizing the possibility of an erroneous prompt. In order to avoid the possibility of an erroneous prompt, a guide plate 24 is designed. The guide plate 24 receives the impact force of the water discharged from the water inlet pipe 3 and guides the impact force of the water to the inner wall of the installation cylinder 21, thereby reducing the impact force borne by the filter screen 22 during use and reducing the elastic indicator device. 25 may give a wrong indication, so that the elastic indicating device 25 can better reflect the amount of impurities on the filter screen 22, which is convenient for the operator to operate under the prompt; then, in order to prevent the filter screen 22 from arbitrarily separating from the mounting tube 21 during use, an elastic limiting device 26 is designed, and the elastic limiting device 26 limits the protrusion 23 in the mounting groove 211 through an elastic member; finally, in order to prevent the elastic limiting device 26 from releasing the protrusion 23 due to the tolerance of the elastic member during use, the positioning portion of the elastic limiting device 26 is designed to be clamped between the pipe cover 16 and the connecting pipe 15.

[0029] The elastic indicating device 25 includes: a bearing plate 251, an indicating rod 252 and a first spring 253. One end of the first spring 253 is fixed to the inner wall of the mounting groove 211, and the other end of the first spring 253 is fixed to the bearing plate 251. The bearing plate 251 is used to bear the protrusion 23. The bearing plate 251 is fixed to one end of the indicating rod 252. The other end of the indicating rod 252 is used to pass through the pipe cover 16. When the indicating rod 252 emerges from the top surface of the pipe cover 16, the indicating rod 252 indicates that there are not many impurities on the filter screen 22. When the indicating rod 252 is retracted into the pipe cover 16, the indicating rod 252 indicates that there are too many impurities on the filter screen 22, reminding the operator to discharge the impurities in the mounting tube 21 in time. The indicating rod 252 and the bearing plate 251 can move in the vertical direction relative to the mounting tube 21 and the pipe cover 16.

[0030] The elastic limiting device 26 includes: a limiting block 261, a connecting rod 262, a second spring 263 and a positioning plate 264. The limiting block 261 is a U-shaped structure. One end of the limiting block 261 is used to close the horizontal guide groove. The other end of the limiting block 261 is fixed to the connecting rod 262. The connecting rod 262 is fixed to one end of the positioning plate 264. The other end of the positioning plate 264 passes through the top side wall of the mounting tube 21. The positioning plate 264 is a positioning part. The second spring 263 is an elastic part. A pulling-assisting hole is opened on the inner wall of the limiting plate. The limiting block 261, the connecting rod 262 and the positioning plate 264 can move in the vertical direction relative to the mounting tube 21.

[0031] The working principle of this embodiment:

[0032] During installation, first, insert the protrusion 23 into the vertical guide groove 210, and slide the protrusion 23 to the top of the vertical guide groove 210; then, manually hook the auxiliary pulling hole so that the limit block 261 releases the horizontal guide groove, and the second spring 263 is compressed; then, rotate the filter screen 22 so that the protrusion 23 slides from the horizontal guide groove into the installation groove 211. At this time, the supporting plate 251 is in the highest position under the support of the first spring 253, but the supporting plate 251 can still allow the protrusion 23 to slide to Above; then, release the limit block 261, and under the elastic force of the second spring 263, the limit block 261 closes the horizontal guide groove, preventing the protrusion 23 from sliding from the installation groove 211 to the vertical guide groove 210; finally, cover the connecting pipe 15 with the pipe cover 16, and the pipe cover 16 clamps the positioning plate 264 between the pipe cover 16 and the connecting pipe 15 to position the limit block 261, avoid the limit block 261 from opening the horizontal guide groove, and connect the pipe cover 16 to the connecting pipe 15 with screws.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
