DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides: a flocculant delivery device for sewage treatment, such as Figure 1-Figure 4 As shown, it includes a sewage tank 1, a cover plate 2 is provided on the top of the sewage tank 1, the bottom of the cover plate 2 is connected to the top of the sewage tank 1, both sides of the bottom of the inner wall of the cover plate 2 are connected with a discharge pipe 3, the bottom of the discharge pipe 3 passes through the bottom of the cover plate 2 and is located inside the sewage tank 1, a motor 4 is provided inside the sewage tank 1, the output shaft of the motor 4 passes through the bottom of the cover plate 2 and is fixedly connected with a disc 5, both sides of the bottom of the disc 5 are movably connected to a limit frame 6 through round blocks, a stopper 7 is fixedly connected to the outer side of the limit frame 6, the top of the stopper 7 contacts the bottom of the discharge pipe 3, a sewage inlet pipe 8 is connected to the top of the left side of the sewage tank 1, a limit block 11 is fixedly connected to the top of both sides of the inner wall of the sewage tank 1, the inner side of the limit block 11 contacts the outer side of the stopper 7, the top of the limit block 11 contacts the bottom of the cover plate 2, the front and rear sides of the top of the limit frame 6 are fixedly connected with a stabilizing block 16, the front and rear sides of the bottom of the cover plate 2 are provided with a stabilizing groove 17, and the stabilizing block 16 and the stabilizing groove 17 are slidably connected.

[0022] In this embodiment, the flocculant to be introduced can be poured into the cover plate 2 by setting structures such as the motor 4, the disc 5, the limit frame 6, the block 7 and the discharge pipe 3. When the flocculant in the cover plate 2 needs to be poured into the sewage tank 1, the motor 4 can be started by the external controller, and the output shaft of the motor 4 drives the disc 5 to rotate. The rotation of the disc 5 drives the limit frame 6 to move inward through the block. The limit frame 6 moves inward and drives the block 7 to move inward to separate it from the discharge pipe 3, so that the flocculant in the cover plate 2 will enter the sewage tank 1. Finally, when the flocculant is introduced, the motor 4 can be reversed to allow the block 7 to limit the discharge pipe 3, so that the discharge of the flocculant in the cover plate 2 can be controlled.

[0023] Preferably, a stirring rod 9 is fixedly connected to the bottom of the disc 5, and the stirring rod 9 is located inside the sewage tank 1. Two groups of stirring blades 10 are fixedly connected to the arc surface of the stirring rod 9. A feed pipe 12 is connected to the top of the cover plate 2. A trapezoidal block 13 is fixedly connected to the bottom of the inner wall of the cover plate 2. A placement groove 14 is provided at the bottom of the trapezoidal block 13. The top of the motor 4 is fixedly connected to the top of the inner wall of the placement groove 14.

[0024] By setting structures such as the stirring rod 9, the stirring blade 10 and the trapezoidal block 13, when the flocculant inside the cover plate 2 enters the sewage tank, the motor 4 can be started through the external controller, and the output shaft of the motor 4 drives the disc 5 to rotate. The rotation of the disc 5 can drive the stirring rod 9 to rotate, and the rotation of the stirring rod 9 drives the stirring blade 10 to rotate. At this time, the rotation of the disc 5 will also drive the limit frame 6 to move inward through the round block. When the inner side of the limit frame 6 contacts the arc surface of the stirring rod 9, the motor 4 can be reversed to make the stirring rod 9 and the stirring blade 10 rotate in the opposite direction, so that the flocculant and sewage entering the sewage tank 1 can be quickly merged.

[0025] Among them, the tops of both sides of the inner wall of the sewage tank 1 are fixedly connected with limit blocks 11, the inner side of the limit block 11 contacts the outer side of the stop block 7, the top of the limit block 11 contacts the bottom of the cover plate 2, and mounting blocks 15 are provided on both sides of the front and rear sides of the cover plate 2. The four corners of the outer side of the mounting block 15 are detachably connected to the cover plate 2 and the sewage tank 1 by bolts.

[0026] In this embodiment, by setting the limit block 11 and the mounting block 15, when a large number of impurities are attached to the inside of the sewage tank 1 and cannot be discharged, the bolts at the four corners of the mounting block 15 can be removed, and the cover plate 2 can be pulled toward the top to separate it from the sewage tank 1, and then the impurities adsorbed in the sewage tank 1 can be processed. The limit block 11 can effectively limit the stop block 7 to prevent the stop block 7 from being unable to completely block the discharge pipe 3 when resetting.

[0027] It is worth noting that the bottom of the right side of the sewage tank 1 is connected to a sewage outlet pipe 18 , and the surface of the sewage outlet pipe 18 is connected to a valve 19 .

[0028] By setting the sewage outlet pipe 18 and the valve 19, the discharge of sewage in the sewage tank 1 can be controlled, thereby preventing the flocculant entering the sewage tank 1 from being unable to fully blend with the sewage.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
