Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0062] In the embodiments of the present invention, please refer to Figures 1 to 9 , a denitrification and dephosphorization reactor for domestic sewage treatment, including a housing 1, the top of the housing 1 is provided with an inlet, the bottom is provided with an outlet, a filter screen ring 2 is threadedly connected to the outlet, a valve is arranged in the outlet, and further includes:

[0065] A sliding rod 5, slidably connected to the driving rod 4, and a threaded groove is arranged at a partial position of the sliding rod 5;

[0066] A telescopic member 6, the top end of which is connected to the bottom end of the driving rod 4, and the bottom end is connected to the bottom end of the sliding rod 5;

[0067] A rotating stirring mechanism 7, one end of which is connected to the sliding rod 5 and the other end is connected to the driving rod 4, and is used for rotating and stirring sewage;

[0068] The lifting and stirring mechanism 8 is connected to the rotating stirring mechanism 7 at one end and the sliding rod 5 at the other end. The lifting and stirring mechanism 8 includes: a water-gathering component 81, connected to the rotating stirring mechanism 7 at one end and the sliding rod 5 at the other end, for gathering the sewage at the bottom of the housing 1 in the central part; a side-pressure component 82, connected to the sliding rod 5 at one end and the water-gathering component 81 at the other end, for stirring and extruding the sewage; and a control component 83, connected to the water-gathering component 81 at one end and the rotating stirring mechanism 7 at the other end, for controlling the operation of the telescopic member 6.

[0085] Sliding folding rod 811, passing through the bottom of the connecting sleeve 72 and being slidably connected thereto;

[0086] Threaded sleeve 812, connected to one end of the sliding folding rod 811 and threadedly connected to the threaded part on the sliding rod 5;

[0088] Support rod one 814, with one end hinged to the threaded sleeve 812;

[0089] Arc plate 816, with the top hinged to the other end of the support rod one 814 and the bottom hinged to the rotating sleeve 813;

[0090] Elastic member 815, arranged inside the connecting sleeve 72, with the top end connected to the connecting sleeve 72 and the bottom end connected to the other end of the sliding folding rod 811.

[0091] In the initial state, there are relatively large gaps between several groups of arc plates 816 to facilitate the entry of sewage. The elastic member 815 is in a stretched state, and the threaded sleeve 812 is located at the bottom of the threaded groove. The driving member 3 drives the driving rod 4 to rotate, the driving rod 4 drives the sliding rod 5 to rotate, the limiting rod 74 drives the threaded sleeve 812 to rotate, and the rotation direction of the sliding rod 5 is opposite to that of the threaded sleeve 812. Under the action of the elastic member 815, the threaded sleeve 812 is threadedly connected to the threaded groove, so that the threaded sleeve 812 drives the sliding folding rod 811 to move upward, the threaded sleeve 812 drives the first support rod 814 to move, and the first support rod 814 drives the arc plate 816 to rotate, causing several groups of arc plates 816 to approach each other. When the threaded sleeve 812 moves to disengage from the threaded groove, at this time, the threaded sleeve 812 cannot continue to move upward, and the elastic member 815 is in a compressed state. The elastic member 815 can be a spring, a spring sheet, etc.

[0092] As an embodiment of the present invention, please refer to Figure 2 , Figure 3 , Figures 7 to 9 , the side pressure assembly 82 includes:

[0093] A connecting plate 821, connected to the arc plate 816;

[0094] A connecting rod 822, connected to the connecting plate 821;

[0095] A rotating cylinder 823, rotatably connected to the connecting rod 822;

[0096] A volute spring 824, disposed inside the rotating cylinder 823, with one end connected to the rotating cylinder 823 and the other end connected to the connecting rod 822;

[0097] A water pressing plate 825, connected to the rotating cylinder 823;

[0098] A power assembly 826, with one end connected to the connecting plate 821 and the other end connected to the sliding rod 5.

[0099] The sliding rod 5 drives the power assembly 826 to move, the power assembly 826 drives the water pressing plate 825 to rotate around the connecting rod 822, and two opposite water pressing plates 825 drive the sewage to move, causing the sewage to impact each other and improving the stirring effect. The setting of the volute spring 824 ensures that the water pressing plate 825 can return to its original position.

[0100] As an embodiment of the present invention, please refer to Figure 2 , Figure 3 , Figures 7 to 9 , the power assembly 826 includes:

[0101] A sector plate 8261, connected to the sliding rod 5;

[0102] A sliding block 8262, slidably connected to the connecting plate 821;

[0103] The second support rod 8263 is hinged to the sliding block 8262 at one end;

[0104] The fixed rod 8264 is hinged to the other end of the second support rod 8263;

[0105] The telescopic rod 8265 is connected to the connecting plate 821 at one end and to the fixed rod 8264 at the other end;

[0106] The roller 8266 is connected to the sliding block 8262 and abuts against the water pressing plate 825.

[0107] The sliding rod 5 drives the sector plate 8261 to rotate, the arc plate 816 drives the fixed rod 8264 to rotate, and the rotation directions of the sector plate 8261 and the fixed rod 8264 are opposite. When the sector plate 8261 contacts the fixed rod 8264, the fixed rod 8264 is squeezed and moves upward, driving the second support rod 8263 to move, the second support rod 8263 drives the sliding block 8262 to move, and the sliding block 8262 drives the roller 8266 to move, thereby squeezing the water pressing plate 825 and causing the two groups of water pressing plates 825 to move relative to each other.

[0108] As an embodiment of the present invention, please refer to Figure 6 , the control assembly 83 includes:

[0109] The first sensing member 831 is disposed inside the connecting sleeve 72 and is connected to the sliding folding rod 811;

[0110] The second sensing member 832 is connected to the inner wall of the connecting sleeve 72 and is located at the bottom of the first sensing member 831;

[0111] The third sensing member 833 is connected to the inner wall of the connecting sleeve 72 and is located at the top of the first sensing member 831.

[0112] The threaded sleeve 812 drives the sliding folding rod 811 to move upward, and the sliding folding rod 811 drives the first sensing member 831 to move upward. When the threaded sleeve 812 can no longer move, the first sensing member 831 contacts the third sensing member 833 and transmits a signal to the controller (not shown in the figure). The controller controls the telescopic member 6 to work, driving the sliding rod 5 to move upward, causing the sewage between several groups of arc plates 816 to rise upward. When the threaded sleeve 812 drives the sliding folding rod 811 to move downward and the threaded sleeve 812 can no longer move, the first sensing member 831 contacts the second sensing member 832 and transmits a signal to the controller. The controller controls the telescopic member 6 to work, driving the sliding rod 5 to move downward.

[0113] The working principle of the present invention is: In the initial state, there is a large gap between several groups of arc plates 816, the elastic member 815 is in a stretched state, and the threaded sleeve 812 is located at the bottom of the threaded groove;

[0114] Pour the sewage and the agent into the interior of the housing 1. The driving member 3 drives the driving rod 4 to rotate. The driving rod 4 drives the sliding rod 5 to rotate. The driving rod 4 drives the first gear 751 to rotate. The first gear 751 drives the second gear 752 to rotate. The second gear 752 drives the toothed ring 754 to rotate. The toothed ring 754 drives the limiting rod 74 to rotate. The limiting rod 74 drives the connecting sleeve 72 to revolve. The connecting sleeve 72 drives the stirring rod 73 to rotate, so as to stir the sewage and the agent.

[0115] Meanwhile, the connecting sleeve 72 drives the sliding folding rod 811 to rotate. The sliding folding rod 811 drives the threaded sleeve 812 to rotate. And the rotating direction of the sliding rod 5 is opposite to that of the threaded sleeve 812. Under the acting force provided by the elastic member 815, the threaded sleeve 812 is threadedly connected with the threaded groove, so that the threaded sleeve 812 drives the sliding folding rod 811 to move upward. The threaded sleeve 812 drives the first support rod 814 to move. The first support rod 814 drives the arc plate 816 to rotate, so that a plurality of groups of arc plates 816 approach each other and the gap shrinks. The sliding folding rod 811 drives the first sensor 831 to move upward synchronously. When the threaded sleeve 812 moves to be disengaged from the threaded groove, at this time, the threaded sleeve 812 cannot continue to move upward, the elastic member 815 is in a compressed state, the first sensor 831 contacts the third sensor 833, and transmits a signal to the controller (not shown in the figure). The controller controls the telescopic member 6 to work, drives the sliding rod 5 to move upward, so that the sewage among a plurality of groups of arc plates 816 is lifted upward, thereby lifting the bottom sewage to the top, ensuring that the sewage and the agent are evenly mixed.

[0116] After lifting the bottom sewage, the driving member 3 rotates in the reverse direction. Under the reaction force of the elastic member 815, the threaded sleeve 812 is threadedly connected with the threaded groove again, so that the threaded sleeve 812 drives the first support rod 814 to move, and the arc plate 816 rotates to return to the initial position.

[0117] The sliding rod 5 drives the sector plate 8261 to rotate. The arc plate 816 drives the fixed rod 8264 to rotate. And the rotating direction of the sector plate 8261 is opposite to that of the fixed rod 8264. When the sector plate 8261 contacts the fixed rod 8264, the fixed rod 8264 is extruded and moves upward, driving the second support rod 8263 to move. The second support rod 8263 drives the sliding block 8262 to move. The sliding block 8262 drives the roller 8266 to move, thereby extruding the water pressing plate 825, so that the two groups of water pressing plates 825 move relatively, and the sewage impacts each other, improving the stirring and mixing effect.
