Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater sediment extraction device. Background Technology

[0002] Wastewater sediment is the material that accumulates at the bottom of a wastewater treatment tank during the sedimentation process. It is usually extracted and discharged using a sewage pump to facilitate subsequent wastewater treatment.

[0003] Currently, conventional sewage sediment extraction equipment lacks the function of stirring and breaking up sediment during use, which leads to problems such as sediment clogging the inlet pipe and damaging the pump blades. In addition, the sediment contains a large amount of liquid, which is extracted along with the sediment. There is no function to separate solids and liquids. Therefore, we propose a sewage sediment extraction equipment to solve the above problems. Utility Model Content

An inlet pipe is fixedly mounted on the inlet of the sewage pump. A mesh plate is fixedly mounted on the inner wall of the inlet pipe near the upper side. A crushing mechanism is provided on the mesh plate. The crushing mechanism is drivenly connected to the shaft of the sewage pump through a connecting mechanism.

Crushing blades are fixedly installed on the rotating shaft at the lower side of the grid plate, and a stirring roller is fixedly installed on the rotating shaft near the lower edge.

[0009] Furthermore, the lower surface of the stirring rod is 3 mm away from the lower surface of the sewage inlet pipe.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-4 As shown in the figure, a wastewater sediment extraction device according to one embodiment of the present invention includes a mounting plate 1. A motor assembly 2 is fixedly mounted on the upper surface of the mounting plate 1. A coupling assembly 3 is mounted on the lower surface of the output shaft of the motor assembly 2. The lower surface of the coupling assembly 3 is connected to a sewage pump 4. An inlet pipe 5 is fixedly mounted on the inlet of the sewage pump 4. A mesh plate 6 is fixedly mounted on the inner wall of the inlet pipe 5 near the upper side. A crushing mechanism 7 is provided on the mesh plate 6. The crushing mechanism 7 is connected to the shaft of the sewage pump 4 through a connecting mechanism 8. A connecting pipe 9 is fixedly mounted on the discharge port of the sewage pump 4. A filter mechanism 10 is fixedly mounted on the left side of the connecting pipe 9.

[0022] like Figure 1 and Figure 2 As shown, in some embodiments, a first flange 11 is fixedly installed on the upper surface of the sewage inlet pipe 5, and the first flange 11 is connected to the sewage pump 4 by a first fastening bolt 12.

[0023] In this embodiment, the first flange 11 is connected to the first fastening bolt 12 for ventilation, which facilitates the installation of the sewage inlet pipe 5 on the sewage inlet of the sewage pump 4, and allows the sewage inlet pipe 5 to be disassembled and assembled.

[0024] like Figure 3 As shown, in some embodiments, the crushing mechanism 7 includes a rotating shaft 701, a bearing assembly 702, a crushing blade 703, and a stirring roller 704. The rotating shaft 701 is fixedly installed in the middle of the grid plate 6 via the bearing assembly 702. The crushing blade 703 is fixedly installed on the rotating shaft 701 at the lower side of the grid plate 6, and the stirring roller 704 is fixedly installed on the rotating shaft 701 near the lower edge.

[0025] In this embodiment, the rotating shaft 701 rotates in the bearing assembly 702, causing the rotating shaft 701 to drive the crushing blade 703 and the stirring rod 704 to rotate. The stirring rod 704 can stir the sediment at the inlet of the sewage pipe 5, so that the sediment is less likely to block the inlet of the sewage pipe 5. The crushing blade 703 crushes the larger sediment filtered out by the mesh plate 6, avoiding damage to the blades of the sewage pump 4 by the larger sediment.

[0026] like Figure 3As shown, in some embodiments, the lower surface of the stirring rod 704 is 3 mm away from the lower surface of the sewage inlet pipe 5.

[0027] In this embodiment, the stirring rod 704 can better stir the sediment coming out of the inlet of the sewage pipe 5.

[0028] like Figure 3 As shown, in some embodiments, the connecting mechanism 8 includes a connecting block 801 and a rectangular groove 802. The connecting block 801 is fixedly installed on the upper surface of the rotating shaft 701. The upper surface of the connecting block is provided with a rectangular groove 802, and the rectangular groove 802 is sleeved on the outside of the shaft of the sewage pump 4.

[0029] In this embodiment, the connecting block 801 can be sleeved on the lower end of the sewage pump 4 shaft through the rectangular groove 802, so that the sewage pump 4 shaft can drive the rotating shaft 701 to rotate through the connecting block 801.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, a second flange 13 is fixedly installed on the right end of the connecting pipe 9, and the second flange 13 is connected to the sewage outlet of the sewage pump 4 by a second fastening bolt 14.

[0031] In this embodiment, the second flange 13 connects the connecting pipe 9 to the sewage outlet of the sewage pump 4 via the second fastening bolt 14, thereby facilitating the disassembly and assembly of the filter mechanism 10.

[0032] like Figure 4 As shown, in some embodiments, the filtration mechanism 10 includes a rectangular box 101, a filter screen 102, a vibration motor 103, and a drain pipe 104. The rectangular box 101 is fixedly installed on the left side of the connecting pipe 9. The filter screen 102 is obliquely fixedly installed between the left and right side walls of the rectangular box 101. The vibration motor 103 is fixedly installed on the upper surface of the rectangular box 101, and the drain pipe 104 is fixedly installed on the lower side wall of the rectangular box 101.

[0033] In this embodiment, the sediment in the connecting pipe 9 flows into the filter screen sleeve 102. Since the filter screen sleeve 102 is tilted, and in conjunction with the vibration motor 103 driving the rectangular box 101 and the filter screen sleeve 102 to vibrate, the sediment in the filter screen sleeve 102 vibrates, so that the liquid in the sediment is filtered out through the filter screen sleeve 102. The filtered liquid is discharged to the outside of the rectangular box 101 through the drain pipe 104.

[0034] In operation, the output shaft of motor assembly 2 drives coupling assembly 3 to rotate, which in turn drives the blades inside sewage pump 4 to rotate. Sewage pump 4 then pumps air from the sediment through inlet pipe 5. The shaft of sewage pump 4 drives connecting block 801 in connecting mechanism 8 to rotate. Connecting block 801 drives rotating shaft 701 in crushing mechanism 7 within bearing assembly 702. This rotating shaft 701 drives the crushing blades 703 and stirring roller 704 to rotate. The stirring roller 704 agitates the sediment at the inlet of inlet pipe 5, preventing clogging. The crushing blades 703 also act as a filter on mesh plate 6. Larger sediments are broken up to prevent damage to the blades of the sewage pump 4. The sewage pump 4 then pumps the sediments through the connecting pipe 9 into the filter screen 102 of the filter mechanism 10. Because the filter screen 102 is tilted, and in conjunction with the vibration motor 103, the rectangular box 101 and the filter screen 102 vibrate, which in turn causes the sediments inside the filter screen 102 to vibrate. This causes the liquid inside the sediments to be filtered out through the filter screen 102. The filtered liquid is discharged outside the rectangular box 101 through the drain pipe 104, while the sediments are discharged through the filter screen 102. This enhances the solid-liquid separation function of the sediments and facilitates their use.

[0035] In summary, this sewage sediment extraction equipment, through the connecting mechanism 8, enables the crushing mechanism 7 to rotate driven by the shaft of the sewage pump 4, which can stir and crush the sediment, making it less likely for the sediment to clog the sewage inlet pipe 5 or damage the blades of the sewage pump 4, increasing the solid-liquid separation function of the sediment, facilitating the separation of solid and liquid, and making it convenient to use.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
