The upper edge of the filter plate 20 is connected with an abutting plate 21 located above the tank body 10, and the abutting plate 21 is locked by a locking assembly 30; the rectangular sealing gasket 40 is connected to the bottom surface of the abutting plate 21 and sleeved on the outer periphery of the filter plate 20 for abutting and cooperating with the top wall of the tank body 10; the cover 50 is detachably connected to the waste discharge pipe 13 for plugging the lower opening of the waste discharge pipe 13.

[0024] Further, the rectangular sealing gasket 40 is used to seal the gap between the abutting plate 21 and the tank body 10 to prevent the waste water inside the tank body 10 from leaking out through the socket 15.

[0025] Further, a valve is provided on the liquid outlet pipe 12.

[0026] Further, the edge of the support plate 14 close to the inner wall of the tank body 10 is connected to the tank body 10. The filter plate 20 and the support plate 14 divide the internal space of the tank body 10 into two parts. One part is used for precipitating plaster, and the other part is communicated with the liquid outlet pipe 12 to accommodate the filtered waste water for discharging the filtered waste water from the liquid outlet pipe 12.

[0027] Further, contact strips 16 extending in the vertical direction are provided on the inner wall of the tank body 10 and are used for contacting and cooperating with the two side edges of the filter plate 20.

[0029] In the actual use process of the dental plaster precipitation device provided by the embodiment of the present application, the valve on the liquid outlet pipe 12 is closed, and the waste water is introduced into the tank body 10 through the liquid inlet pipe 11 until the tank body 10 is filled with waste water. The plaster in the waste water is allowed to settle statically. After a period of time, the liquid outlet pipe 12 is opened, and the waste water filtered by the filter plate 20 is discharged from the liquid outlet pipe 12 and discharged to the sewer. After the discharge is completed, a waste storage box is prepared and placed below the waste discharge pipe 13. The cover 50 is opened to discharge the precipitated plaster into the waste storage box, and then the filtration treatment of the waste water can be completed.

[0030] When it is necessary to clean the filter plate 20, unlock the locking component 30 from locking the abutting plate 21, and then pull up the abutting plate 21 to draw out the filter plate 20 from the socket 15, and clean the filter plate 20. After the cleaning is completed, blockage of the filter plate 20 is avoided to ensure the filtering effect.

[0031] Compared with the prior art, for the dental plaster precipitation device provided in this embodiment, when it is necessary to clean the filter plate 20, unlock the locking component 30 from locking the abutting plate 21, and then pull up the abutting plate 21 to draw out the filter plate 20 from the socket 15, and clean the filter plate 20. After the cleaning is completed, blockage of the filter plate 20 is avoided to ensure the filtering effect.

[0032] In a possible implementation manner, the above-mentioned locking component 30 adopts the structure as shown in Figure 1 See Figure 1 , the locking component 30 includes a guide rod 31 and a locking sleeve 32. The guide rod 31 is arranged at the top of the tank body 10 and penetrates upward through the abutting plate 21; the locking sleeve 32 is threadedly sleeved on the outer periphery of the guide rod 31 and is located above the abutting plate 21 for rotating and pressing down the abutting plate 21.

[0033] Specifically, the abutting plate 21 is slidably matched with the guide rod 31. When it is necessary to disassemble the filter plate 20, only need to rotate the locking sleeve 32 away from the guide rod 31, and then pull up the abutting plate 21 to disassemble the filter plate 20, realizing the quick disassembly of the filter plate 20.

[0034] And by pressing and fixing the abutting plate 21 with the locking sleeve 32, the rectangular sealing gasket 40 can be pressed against the top of the tank body 10 to enhance the sealing performance at the socket 15.

[0035] In some embodiments, see Figure 1 , two groups of locking components 30 are symmetrically arranged on the abutting plate 21.

[0036] Specifically, the arrangement of the two groups of locking components 30 can further enhance the sealing performance at the socket 15.

[0037] In some embodiments, see Figure 1 , a force-applying block 33 extending outward is arranged on the outer peripheral wall of the locking sleeve 32.

[0038] Specifically, the arrangement of the force-applying block 33 can facilitate the staff to rotate the locking sleeve 32, improving the practicability.

[0039] In some embodiments, see Figure 1 , a flexible gasket 60 for abutting and cooperating with the lower edge of the filter plate 20 is arranged on the top wall of the support plate 14.

[0040] Specifically, the flexible pad 60 is provided such that during the process of the locking assembly 30 abutting against the locking abutting plate 21, not only can the abutting plate 21 press down the rectangular gasket 40 to the top of the tank body 10, but also the lower edge of the filter plate 20 can be in close contact with the flexible pad 60, enhancing the filtering effect of the filter plate 20.

[0041] In a possible implementation manner, the above-mentioned tank body 10 adopts the structure as shown in Figure 1 See Figure 1 . Inside the tank body 10, a disturbing member 70 is provided along the up-and-down direction.

[0042] Specifically, when it is necessary to discharge the precipitated gypsum, the rotation driving member 71 drives the disturbing vanes 73 to rotate through the rotating shaft 72, thereby disturbing the gypsum inside the tank body 10, increasing its fluidity, facilitating the discharge of the gypsum, realizing the automatic disturbance of the gypsum inside the tank body 10, and saving manpower.

[0043] In some embodiments, see Figure 1 . The lower end of the rotating shaft 72 is connected with a screw conveyor 80 that extends downward into the impurity discharge pipe 13 and is used for downwardly conveying the gypsum in the impurity discharge pipe 13.

[0044] Specifically, while the gypsum is output from the impurity discharge pipe 13, the rotating shaft 72 drives the screw conveyor 80 to rotate, assisting the output of the gypsum in the impurity discharge pipe 13 and preventing the blockage of the impurity discharge pipe 13.

[0045] In some embodiments, see Figure 1 . The lower part of the tank body 10 gradually converges towards the central axis from top to bottom.

[0046] Specifically, the inner wall of the lower part of the tank body 10 is in a funnel shape, facilitating the aggregation of the gypsum towards the impurity discharge pipe 13 and facilitating the discharge of the impurity discharge pipe 13 in the later stage.

[0047] In some embodiments, see Figure 1 . The outer end of the disturbing vane 73 is connected with a scraping strip 90 that extends along the slope direction of the tank body 10 and is used for scraping the gypsum on the inner wall of the tank body 10.

[0048] Specifically, the scraping strip 90 extends along the inclined direction of the inner wall of the tank body 10, facilitating the close contact between the scraping strip 90 and the inner wall of the tank body 10, enabling the scraping strip 90 not only to cooperate with the disturbing vane 73 to disturb the gypsum, but also to clean the gypsum on the inner wall of the tank body 10, preventing the gypsum from adhering to the inner wall of the tank body 10.

[0049] In some embodiments, seeFigure 1 The cover 50 is threadedly connected to the impurity discharge pipe 13.

[0050] Specifically, the threaded connection between the cover 50 and the impurity discharge pipe 13 can not only enhance the sealing effect on the impurity discharge pipe 13, but also facilitate the installation and disassembly of the cover 50, improving the practicality.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
