Description

Technical Field

[0001] The utility model belongs to the field of sewage filtering devices, and in particular relates to a sewage extraction and filtering device for preventing and controlling water environment pollution. Background Art

[0002] A sewage filtration device, also known as a sewage filter, is a device used to treat sewage. It uses physical or biological filtration techniques, such as filters, grids, sedimentation tanks or bioreactors, biofilms, etc., to separate or decompose harmful substances in sewage to achieve the purpose of purifying water quality.

[0003] During the use of the sewage filtration device, since it treats sewage containing various substances, these substances provide conditions for the growth of microorganisms. Therefore, bacteria and other microorganisms are prone to grow inside the sewage filtration device. These microorganisms will affect the filtering effect, and it is necessary to manually sterilize the inside of the sewage filtration device. However, sterilization inside the sewage filtration device wastes manpower, and due to human factors, it is easy to cause the sterilization to be careless, and the corners inside the sewage filtration device are not completely cleaned. Utility Model Content

[0004] The utility model discloses a sewage extraction and filtration device for preventing and controlling water environment pollution, which is used for mechanized sterilization inside the sewage extraction and filtration device.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a sewage filtration device for water environment pollution prevention and control, comprising a filtration device body, a steam sterilization mechanism and a steam outlet mechanism are arranged on the side wall of the filtration device body;

[0006] Steam sterilization mechanisms include:

[0007] A support frame is fixed on the outer wall of the suction filtration device body;

[0008] The connecting shell is fixed on the supporting frame; a heating device is placed in the connecting shell; a through hole is opened on the connecting shell;

[0009] A liquid storage tank, the lower end of which passes through the through hole and is placed on the heating device;

[0010] The liquid injection pipe is fixedly connected to the liquid storage tank and can be communicated with the internal cavity of the liquid storage tank; a screw cap for sealing the liquid injection pipe is threadedly connected to the liquid injection pipe;

[0011] The steam inlet pipe has one end connected to the liquid storage tank and the other end connected to the filter chamber inside the suction filter device body; a steam inlet valve is installed on the steam inlet pipe;

[0012] The steam outlet mechanism includes:

[0013] The steam outlet pipe has one end connected to the filter cavity inside the suction filter device body and the other end connected to the atmosphere; a steam outlet valve is installed on the steam outlet pipe;

[0014] A pressure regulating mechanism for maintaining the pressure of the filter chamber inside the suction filtration device body.

[0015] The disinfectant is heated by a heating device so that the disinfectant becomes steam and enters the filter chamber inside the suction filtration device body. The pressure regulating mechanism is designed so that before the pressure of the filter chamber inside the suction filtration device body reaches the preset pressure, the disinfectant can diffuse to as many places as possible in the filter chamber inside the suction filtration device body, thereby achieving the purpose of disinfecting various places in the filter chamber inside the suction filtration device body.

[0016] Furthermore, the voltage regulating mechanism comprises:

[0017] The limit block is installed on the inner wall of the steam outlet pipe; the side of the limit block facing the suction filtration device body is set as the X side, and the other side is set as the Y side;

[0018] The movable rod is inserted into the limit block, and a through hole is provided on the limit block for the movable rod to pass through. The axis of the movable rod coincides with the axis of the steam outlet pipe, and the movable rod can slide along its axis. The end of the movable rod facing the suction filter device body is set as end A, and the other end is set as end B.

[0019] The anti-dropping nut is threadedly connected to the A end of the movable rod, and the diameter of the anti-dropping nut is larger than the diameter of the perforation; the anti-dropping nut is located on the X side of the limit block, and the anti-dropping nut does not abut against the X side surface of the limit block;

[0020] The clamping plate is installed at the B end of the movable rod; the side of the clamping plate facing the suction filtration device body is the M side, and the other side is the N side;

[0021] The clamping groove is provided on the end surface of the steam outlet pipe away from the suction filter device body;

[0022] The spring is sleeved on the movable rod, one end of which is fixedly connected to the M side of the card plate; the other end is fixedly connected to the Y side of the limit block; the spring is in a stretched state; under the elastic force of the spring, the card plate abuts against the card slot.

[0023] A spring is used. When the internal pressure of the filter chamber inside the suction filter device body is too high, the spring is automatically stretched, so that the clamping plate and the clamping slot are opened, allowing steam to be discharged from the filter chamber inside the suction filter device body.

[0024] Furthermore, a slide groove for sliding the limit block is provided on the inner wall of the steam outlet pipe; a first threaded hole is provided on the side wall of the filtration device body, and a second limit hole is provided on the limit block. A connecting bolt is threadedly connected in the first threaded hole, and the end of the connecting bolt is inserted into the second limit hole.

Whether disassembling or installing the pressure regulating mechanism, the entire pressure regulating mechanism can be slid out from the end of the slide groove by simply tightening or loosening the connecting bolts. The operation is convenient and the structure is simple.

[0026] Furthermore, the support frame includes a vertical section and a horizontal ring section, the vertical section is welded to the outer wall of the suction filtration device body; the horizontal ring section is horizontally arranged in a circular shape, and the horizontal ring section is sleeved on the liquid storage tank.

[0027] A horizontal ring section is provided, which can be sleeved on the liquid storage tank and can support the middle position of the liquid storage tank to ensure the stability of the liquid storage tank placed on the connecting shell.

[0028] Furthermore, the clamping plate is threadedly connected to the B end of the movable rod.

[0029] After the clamping plate is removed from the movable rod, the spring can also be removed from the movable rod, and the anti-dropping nut and the limit block can also be detached, so the clamping plate is threadedly connected to the movable rod, which can facilitate the disassembly of the entire pressure regulating mechanism.

[0030] Furthermore, the steam outlet valve is located between the suction filtration device body and the pressure regulating mechanism.

[0031] This is to prevent sewage from passing through the pressure regulating mechanism when the steam valve is opened, that is, when the entire device is used to filter sewage. This way, there will be no contamination of the pressure regulating mechanism by sewage, and the use of the pressure regulating mechanism will not be affected by sewage. Beneficial Effects

The operator can inject disinfectant into the cavity of the liquid storage tank 103 through the injection tube 104. The injection tube 104 is threadedly connected with a screw cap 106 for sealing the injection tube 104.

[0047] The steam inlet pipe 105 is connected to the liquid storage tank 103 at one end and communicates with the cavity inside the liquid storage tank 103; the other end is communicated with the filter cavity inside the suction filtration device body 1. A steam inlet valve 107 is installed on the steam inlet pipe 105, and the operator can manually control the opening and closing of the steam inlet valve 107 to realize the opening and closing of the steam inlet pipe 105.

[0048] See Figure 2 The steam outlet mechanism 20 comprises:

[0049] The steam outlet pipe 21 has one end connected to the filter cavity inside the suction filter body 1, and the other end connected to the atmosphere outside the suction filter body 1. Figure 2 From the perspective of the right end, the filter chamber inside the suction filter body 1 is connected to the filter chamber, and the atmosphere outside the suction filter body 1 is connected to the left end. A steam outlet valve 210 is installed on the steam outlet pipe 21, and the operator can manually control the opening and closing of the steam outlet valve 210 to realize the opening and closing of the steam outlet pipe 21. The steam outlet valve 210 is set at a position where the steam outlet pipe 21 is close to the suction filter body 1.

[0050] The pressure regulating mechanism is arranged on the inner wall of the steam outlet pipe 21, and is used to prevent the pressure inside the suction filter device body 1 from being too high. The pressure regulating mechanism is located at the end of the steam outlet pipe 21 away from the suction filter device body 1, that is, the steam outlet valve 210 is located between the suction filter device body 1 and the pressure regulating mechanism. The steam inside the steam outlet pipe 21 first passes through the steam outlet valve 210, and then passes through the pressure regulating mechanism. The pressure regulating mechanism includes:

[0051] The limit block 22 is installed on the inner wall of the steam outlet pipe 21. In this embodiment, a slide groove 23 for the limit block 22 to slide is provided on the inner wall of the steam outlet pipe 21. The end of the steam outlet pipe 21 close to the suction filtration device body 1 is assumed to be the inlet end, and the other end is assumed to be the outlet end. The length direction of the slide groove 23 is along the axial direction of the steam outlet pipe 21, and the corresponding end of the slide groove 23 extends to the outlet end face of the steam outlet pipe 21. In other words, the limit block 22 can slide from the outlet end face of the steam outlet pipe 21 into the slide groove 23, and the limit block 22 can slide to the end of the slide groove 23. Two first bolt holes (not shown) are provided on the steam outlet pipe 21, and the first bolt holes are arranged along the radial direction of the steam outlet pipe 21. Second limit holes 24 corresponding to the first bolt holes are provided on both ends of the limit block 22. When the limit block 22 slides to the end of the slide groove 23, it is threadedly connected to the first bolt hole through the connecting bolt, and the end of the connecting bolt is inserted into the second limit hole 24, so that the limit block 22 is installed on the steam outlet pipe 21. The side of the limit block 22 facing the suction filtration device body 1 is set as the X side, and the other side is set as the Y side.

[0052] The movable rod 25 is inserted into the stop block 22. The stop block 22 is provided with a through hole for the movable rod 25 to pass through. In this embodiment, the axis of the movable rod 25 coincides with the axis of the steam outlet pipe 21. The movable rod 25 is movably clamped on the stop block 22, and the movable rod 25 can slide relative to the stop block 22 along its axis. The end of the movable rod 25 facing the suction filtration device body 1 is set as end A, and the other end is set as end B.

[0053] The anti-dropping nut 26 is threadedly connected to the A end of the movable rod 25, and the diameter of the anti-dropping nut 26 is larger than the diameter of the perforation. The anti-dropping nut 26 is located on the X side of the limit block 22. The anti-dropping nut 26 does not abut against the X side surface of the limit block 22.

[0054] The clamping plate 27, in this embodiment, is disc-shaped, the axis of the clamping plate 27 coincides with the axis of the movable rod 25, and the clamping plate 27 is threadedly connected to the B end of the movable rod 25. The side of the clamping plate 27 facing the suction filtration device body 1 is the M side, and the other side is the N side.

[0055] The clamping groove 28 is formed by cutting from the outlet end surface of the steam outlet pipe 21 along the axis of the steam outlet pipe 21. The shape of the clamping groove 28 matches the shape of the clamping plate 27.

[0056] The spring 29 is sleeved on the movable rod 25. One end of the spring 29 is fixedly connected to the M side of the clamping plate 27, and the other end of the spring 29 is fixedly connected to the Y side of the limit block 22, and the spring 29 is in a stretched state. Under the action of the spring 29, the M side of the clamping plate 27 abuts against the clamping groove 28. When the pressure inside the suction filter body 1 is too high, the air pressure inside the suction filter body 1 will force the spring 29 to extend, so that the clamping plate 27 can be completely separated from the clamping groove 28.

[0057] The use process of this device is:

[0058] First, manually close the valves on the liquid inlet pipe 30, the liquid outlet pipe 31 and the sewage pipe 32 respectively, so that the entire device no longer filters sewage.

[0059] Then manually open the steam inlet valve 107 and the steam outlet valve 210, inject disinfectant into the liquid storage tank 103 through the liquid injection pipe 104, and manually screw on the screw cap 106;

[0060] Then, the heating device 108 is manually turned on. The disinfectant is heated into steam and enters the internal filter cavity of the suction filtration device body 1 to achieve sterilization of the internal filter cavity of the suction filtration device body 1.

[0061] When the pressure in the filter cavity inside the suction filtration device body 1 is too high, the spring 29 is stretched, the movable rod 25 and the clamping plate 27 slide along their axis relative to the limit block 22 as a whole, the clamping plate 27 is separated from the clamping groove 28, and the steam can be discharged from the filter cavity inside the suction filtration device body 1 from the clamping groove 28. After heating for a set time threshold, the steam inlet valve 107 and the steam outlet valve 210 are manually closed, and the valves on the liquid inlet pipe 30, the liquid outlet pipe 31 and the sewage pipe 32 are manually opened again to filter the sewage again.

[0062] Installation process of steam outlet mechanism 20:

[0063] The clamping plate 27, the movable rod 25, the spring 29, the limit block 22 and the anti-falling nut 26 are connected into a whole, the limit block 22 of the above-mentioned whole is slid into the bottom end of the slide groove 23, the connecting bolt is screwed into the first threaded hole on the outer wall of the steam outlet pipe 21, and the connecting bolt is inserted into the second limit hole 24 of the limit block 22, so as to achieve the purpose of installing the entire steam outlet mechanism 20 on the steam outlet pipe 21.

[0064] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description.
