DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-5The sewage treatment equipment includes a treatment box 1, which is connected to a water inlet pipe 2, a treatment agent storage tank 3 is installed on the treatment box 1, a rotating shaft 6 is rotatably connected inside the treatment box 1, and a plurality of stirring rods 7 are fixedly connected to the rotating shaft 6. The stirring rods 7 can stir and mix the treatment agent and sewage to improve the efficiency of sewage treatment. A plurality of drainage holes 8 are opened on the stirring rods 7. A connector for connecting the drainage holes 8 and the treatment agent storage tank 3 is provided inside the treatment box 1, and a pump liquid component for pumping the treatment agent into the drainage holes 8 is provided inside the treatment box 1.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The connecting part includes a liquid inlet pipe 4 connected to the side wall of the treatment agent storage tank 3, a pressure valve 5 is installed on the liquid inlet pipe 4, a connecting cavity 9 is provided between the rotating shaft 6 and the stirring rod 7, the connecting cavity 9 is connected to the drainage hole 8, a rotating joint 10 is installed on the rotating shaft 6, the connecting cavity 9 is connected to the liquid inlet pipe 4 through the rotating joint 10, and the treatment agent can be sprayed to different positions in the treatment box 1 by using the drainage hole 8, thereby ensuring the sufficient mixing of the treatment agent and the sewage.

[0028] Reference Figure 3 and Figure 5 The pump liquid assembly includes a sleeve 17 fixedly connected to the inner side of the treatment box 1, the sleeve 17 is sealed and slidably connected to a sliding plug 20, the sliding plug 20 is fixedly connected to a sliding cylinder 16, the sliding cylinder 16 extends to the outside of the sleeve 17 at one end away from the sliding plug 20, the sliding cylinder 16 is internally threadedly connected to a threaded rod 15, the sleeve 17 is connected to an air outlet pipe 18 and an air inlet pipe 21, the air outlet pipe 18 is connected to the inside of the treatment agent storage tank 3, and both the air outlet pipe 18 and the air inlet pipe 21 are provided with a one-way valve, The flow limiting directions of the two one-way valves are opposite, so that when the sliding plug 20 moves, the air in the sleeve 17 can be pressed into the treatment agent storage tank 3, and when it moves in the opposite direction, the external air can be sucked into the sleeve 17 to prevent the treatment agent from being sucked into the sleeve 17, so that the device can be reused. The internal sealing sliding connection of the treatment agent storage tank 3 is connected with a pressure plate 19, and the pump liquid assembly also includes a driving member, which is located inside the treatment box 1, and the driving member is used to drive the threaded rod 15 and the rotating shaft 6 to rotate.

[0029] Reference Figure 2 and Figure 5The driving member includes a worm 11 rotatably connected to the inner side of the treatment box 1. A torsion spring 14 is provided between the inner side of the treatment box 1 and the worm 11. The torsion spring 14 can reset the worm 11 when all the sewage enters the treatment box 1, so that the slide plug 20 can move and reset in the opposite direction, so that the device can be reused. The reset of the torsion spring 14 can drive the rotating shaft 6 to reverse, thereby driving the rotating shaft 6 and the stirring rod 7 to stir and mix the liquid in the treatment box 1 again. A plurality of driving blades 12 are fixedly connected to the worm 11, wherein A driving blade 12 is arranged opposite to the water inlet pipe 2, so that when sewage is poured into the water inlet pipe 2, the sewage can exert a force on the driving blade 12, thereby driving the worm 11 to rotate. The worm 11 is axially connected to the threaded rod 15, and a worm wheel 13 is fixedly sleeved on the rotating shaft 6. The worm wheel 13 and the worm 11 are meshed with each other. By setting up a driving component, the treatment agent will be added into the treatment box 1 when the sewage is poured, and the amount of the treatment agent will increase with the increase of sewage. In this way, there is no need for manual operation by the staff, thereby reducing labor costs.

[0030] Reference Figure 5 The sleeve 17 is provided with an escape opening for the sliding cylinder 16 to pass through. The cross-section of the escape opening is a rectangular structure. The escape opening is adapted to the side wall of the sliding cylinder 16. The escape opening serves as a limit for the sliding cylinder 16, so that the rotation of the threaded rod 15 does not drive the sliding cylinder 16 to rotate, but drives the sliding cylinder 16 to move, thereby achieving the purpose of controlling the air inside the sleeve 17.

[0031] Reference Figure 1 The liquid inlet pipe 4 is a plastic hard pipe. Under the action of the rotary joint 10, the rotation of the rotating shaft 6 will not drive the liquid inlet pipe 4 to rotate, and the connecting cavity 9 can always be kept connected with the liquid inlet pipe 4.

[0032] The specific working principle of the utility model is as follows:

[0033] During operation, sewage is discharged into the treatment box 1 through the water inlet pipe 2. When the sewage is poured into the treatment box 1, it will first rush towards one of the driving blades 12. The driving blade 12 will rotate due to the thrust, so that the other driving blade 12 is opposite to the sewage and is thrusted to rotate again. In this way, the sewage pouring downward can make the driving blade 12 rotate and drive the worm 11 to rotate. At this time, the torsion spring 14 is in a stretched state, and the rotation of the worm 11 can drive the threaded rod 15 to rotate. Under the guidance of the avoidance opening on the sleeve 17, the rotation of the threaded rod 15 will not drive the rotation of the sliding cylinder 16, but drive the sliding cylinder 16 to move, and then drive the sliding plug 20 to move. The movement of the sliding plug 20 can squeeze the air in the sleeve 17, so that the air enters the treatment agent storage tank 3 through the air outlet pipe 18. The inflation pressure inside the treatment agent storage tank 3 increases, which will squeeze the pressure plate 19. The pressure plate 19 moves downward to squeeze the treatment agent, and the increased pressure in the treatment agent can make the pressure valve 5 in an open state, so that the treatment agent can enter the interior of the connecting chamber 9 through the liquid inlet pipe 4, and then spray out through multiple drainage holes 8. On the contrary, after all the sewage is poured into the treatment box 1, the driving fan blade 12 is no longer subjected to the force. Under the action of the torsion spring 14, the worm 11 reverses to make the sliding plug 20 move in the opposite direction, and the external air is sucked into the sleeve 17 through the air inlet pipe 21, so that the device can be reused. At this time, the interior of the treatment agent storage tank 3 is no longer inflated, and the pressure valve 5 is no longer under pressure and is in a closed state, so that the treatment agent will no longer be added to the interior of the treatment box 1. Through the above steps, the amount of treatment agent added to the treatment box 1 can be flexibly adjusted according to the amount of sewage, without the need for naked eye observation and manual operation by the staff, thereby improving the accuracy of sewage treatment and reducing the workload of the staff;

[0034] In the above process, when the worm 11 rotates, it will drive the worm wheel 13 and the rotating shaft 6 to rotate, and the stirring rod 7 can fully mix the treatment agent with the sewage to speed up the sewage treatment. Secondly, since the drainage holes 8 are distributed on the stirring rod 7, the treatment agent can be sprayed at different positions inside the treatment box 1 through the drainage holes 8, which improves the full mixing of the treatment agent and sewage, ensures the quality of sewage treatment, and improves the treatment efficiency.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
