Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and specifically relates to sewage treatment equipment with a solid-liquid separation structure. Background Art

[0002] When sewage treatment equipment is treating sewage, it usually separates solid impurities and liquids through a solid-liquid separation structure;

[0003] For example, a Chinese patent with the authorization announcement number CN212789975U discloses a solid-liquid separation device for domestic sewage treatment, which can automatically squeeze the separated dirt to squeeze out the sewage inside it, thereby improving the separation effect;

[0004] However, the solid impurities accumulated in the solid-liquid separation structure during separation. When the solid impurities accumulated, the water contained in the solid impurities in the middle was difficult to be discharged, resulting in residual water.

[0005] At the same time, some equipment will push the solid impurities to complete the automatic discharging of solid impurities, reducing the accumulation of solid impurities inside the solid-liquid separation structure. However, when the solid impurities are pushed, the solid impurities are easily pushed together due to the thrust, resulting in accumulation and residual water. Utility Model Content

[0006] The purpose of the present invention is to provide a sewage treatment equipment with a solid-liquid separation structure, which can reduce the accumulation of solid impurities when discharging after solid-liquid separation of sewage, and reduce the residual moisture inside the solid impurities.

[0009] Furthermore, the elastic push frame includes two groups of rocker arms located at the lower side of the filter, and the two groups of rocker arms are rotatably connected to the inner walls on both sides of the shell respectively. The lower end of the rocker arm is rotatably connected to the inner wall of the shell, and the upper end of the rocker arm is rotatably connected to the mesh frame. The shell is also equipped with an energy storage elastic group that drives the mesh frame to move and reset toward the direction close to the discharge port.

[0010] Furthermore, the energy storage elastic group includes a small bracket fixedly connected to the inner wall of the shell and located at a position of the rocker arm close to the discharge port, and a spring is installed between the rocker arm and the small bracket.

The pressure plate and the filter are arranged in parallel, and baffles are fixedly connected to the front and rear ends of the pressure plate.

[0012] Furthermore, the upper end of the rocker arm is inclined toward an end away from the discharge port, and the angle between the rocker arm and the horizontal plane is 60-75°.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model relates to a sewage treatment device with a solid-liquid separation structure, which drives the filter to move by means of an elastic pushing frame and a pulling force group, and can utilize the inertia of the movement of the filter to drive the solid impurities on the upper side of the filter to move forward, thereby reducing the accumulation of solid impurities on the upper side of the filter, thereby reducing the residual water phenomenon caused by the difficulty of liquid flowing out of the solid impurities due to the accumulation of solid impurities.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-2 As shown, a sewage treatment equipment with a solid-liquid separation structure includes a shell 1, a feed port 2 is opened at the rear end of the upper side of the shell 1, a mesh frame 5 is assembled inside the shell 1, and a filter screen 6 is fixedly connected to the mesh frame 5. When the sewage enters the shell 1 through the feed port 2, it will fall on the filter screen 6 inside the shell 1. After being filtered by the filter screen 6, solid impurities will be left on the upper side of the filter screen 6, and the liquid will flow into the lower part of the shell 1. The lower part of the shell 1 is fixedly connected with a drain pipe group 4, and the drain pipe group 4 is a combination of a pipe and a valve. The liquid inside the shell 1 can be discharged through the drain pipe group 4.

[0023] In order to reduce the accumulation of solid impurities on the filter screen 6, a discharge port 3 is opened at the front end of the shell 1, and the front ends of the mesh frame 5 and the filter screen 6 extend to the outside of the shell 1 through the discharge port 3. The solid impurities can be discharged by discharging them through the front side of the discharge port 3.

[0024] See also Figure 1-3 As shown, in order to drive the solid impurities on the upper side of the discharge port 3 to move forward, the shell 1 is internally installed with an elastic push frame that drives the net frame 5 to move quickly forward and a tension group that drives the net frame 5 to move back at a uniform speed and reset, and the tension group can be separated from the net frame 5;

[0025] At this time, when solid impurities fall on the upper side of the filter 6, the elastic force pushes the frame to drive the mesh frame 5 and the filter 6 to move quickly toward the front side, and the inertia of the mesh frame 5 and the filter 6 is used to drive the solid impurities to move toward the front side, and the solid impurities fall more evenly on the upper side of the filter 6 under the action of inertia, thereby reducing the accumulation of solid impurities on the upper side of the filter 6, thereby reducing the residual moisture caused by the difficulty of liquid flowing out of the solid impurities due to the accumulation of solid impurities.

[0026] like Figure 3 As shown, the front ends of the mesh frame 5 and the filter screen 6 are inclined downward, so that under the action of gravity and the inclination, the solid impurities on the filter screen 6 can slide along the slope of the filter screen 6 toward the front end of the filter screen 6 until they slide off the front end of the filter screen 6, thereby better moving the solid impurities.

[0027] The elastic force push frame can drive the net frame 5 and the filter screen 6 to move linearly toward the front side, that is, drive the net frame 5 to move upward toward the front end, and the elastic force push frame can also drive the net frame 5 and the filter screen 6 to move parabolically toward the front side;

[0028] like Figure 2-4As shown, the technical solution is preferably parabolic movement, which is specifically that the elastic push frame includes two groups of rocker arms 11 located at the lower side of the filter screen 6, and the two groups of rocker arms 11 are rotatably connected to the inner walls on both sides of the shell 1, and the number of each group of rocker arms 11 is multiple. The lower end of the rocker arm 11 is rotatably connected to the inner wall of the shell 1, and the upper end of the rocker arm 11 is rotatably connected to the net frame 5. When the tension group pulls the net frame 5, it will drive the upper end of the rocker arm 11 to rotate in the direction away from the discharge port 3. The shell 1 is also equipped with a device that drives the net frame 5 to move closer to the discharge port. 3. An energy storage elastic group is provided for moving and resetting in the 3-direction. When the upper end of the rocker arm 11 rotates in the direction away from the discharge port 3, the energy storage elastic group stores energy. When the tension group and the mesh frame 5 are separated, under the elastic force of the energy storage elastic group, the rocker arm 11 will quickly push the mesh frame 5, so that the mesh frame 5 drives the filter screen 6 to move in a rapid arc. When the filter screen 6 moves, it will drive the solid impurities on its upper side to move in a parabolic motion. By scattering the solid impurities, the accumulation of solid impurities on the upper side of the filter screen 6 can be further reduced.

[0029] Specifically, the energy storage elastic group includes a small bracket 13 fixedly connected to the inner wall of the shell 1 and located at the rocker arm 11 near the discharge port 3. A spring 12 is installed between the rocker arm 11 and the small bracket 13. At this time, when the rocker arm 11 rotates, energy is stored through the deformation of the spring 12. When the energy storage is completed, the reset tension of the spring 12 can drive the net frame 5 and the filter screen 6 to move quickly.

[0030] At the same time, the energy storage elastic group can also be replaced by two magnets with mutually repelling magnetism, and the filter screen 6 can be driven to move by the repulsive force of the magnets.

[0031] Among them, Figure 2-3 As shown, the pulling force group includes a magnetic plate 9 and an electromagnet 10 that repel each other magnetically. The magnetic plate 9 is fixedly connected to the lower side of the net frame 5, and the electromagnet 10 is fixedly connected to the inner wall of the shell 1. The upper end height of the electromagnet 10 is lower than the lower end height of the rocker arm 11. At this time, when the electromagnet 10 is powered on and started, the magnetic plate 9 will be pulled to drive the net frame 5 to move. When the electromagnet 10 is powered off, the magnetic adsorption of the magnetic plate 9 will stop.

[0032] At the same time, an electric push rod 7 can be fixedly connected to the inner wall at the top of the shell 1 according to user needs. The output end of the electric push rod 7 at the lower end is fixedly connected to a pressure plate 8. The pressure plate 8 and the filter 6 are arranged in parallel. At this time, when the electric push rod 7 drives the pressure plate 8 to descend, the solid impurities on the upper side of the filter 6 will be pressurized through the pressure plate 8, so that the moisture in the solid impurities can be quickly filtered through the filter 6. Moreover, since the elastic pushing frame can drive the filter 6 to move quickly in an arc, inertia can be used to reduce the phenomenon of solid impurities remaining inside the filter mesh of the filter 6.

[0033] At the same time, the pressing plate 8 presses the filter screen 6 and the mesh frame 5, and the magnetic pulling force of the electromagnet 10 can drive the mesh frame 5 and the magnetic plate 9 to move, so as to better drive the mesh frame 5 and the filter screen 6 to move.

[0034] In order to reduce the phenomenon that solid impurities move to the upper side of the pressing plate 8 when the pressing plate 8 pressurizes the filter screen 6 , baffles 14 are fixedly connected to the front and rear ends of the pressing plate 8 .

[0035] In order to make the movement of the net frame 5 compatible with the movement of the pressing plate 8 and reduce the jamming phenomenon, the upper end of the rocker arm 11 is inclined toward the end away from the discharge port 3, that is, the angle a1 between the rocker arm 11 and the horizontal plane is 60-75°. Figure 4 The virtual horizontal line 15 is used as the indicator.

[0036] The working principle of the utility model is: sewage enters the shell 1 through the feed port 2, and the sewage falls on the filter screen 6 inside the shell 1. After being filtered by the filter screen 6, solid impurities will be left on the upper side of the filter screen 6, and the liquid will flow into the lower part of the shell 1 and then be discharged through the drainage pipe group 4.

[0037] At this time, the magnetic plate 9 is started to drive the mesh frame 5 and the filter screen 6 to move downward, and the rocker arm 11 is used to drive the mesh frame 5 and the filter screen 6 to move backward. When the rocker arm 11 moves, energy is stored through the spring 12. When the electromagnet 10 is powered off, the elasticity of the spring 12 will quickly drive the mesh frame 5 and the filter screen 6 to move in an arc. When the filter screen 6 moves, it will drive the solid impurities on its upper side to move in a parabolic motion. By throwing the solid impurities, the accumulation of solid impurities on the upper side of the filter screen 6 can be further reduced, thereby reducing the residual moisture caused by the difficulty of liquid flowing out of the solid impurities due to the accumulation of solid impurities.

[0038] In summary, the technical solution drives the filter 6 to move through the elastic push frame and the pulling force group, and can use the inertia of the movement of the filter 6 to drive the solid impurities on the upper side of the filter 6 to move toward the front side, thereby reducing the accumulation of solid impurities on the upper side of the filter 6, thereby reducing the residual moisture caused by the difficulty of liquid flowing out of the solid impurities due to the accumulation of solid impurities.

[0039] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
