Description

Technical Field

[0001] The utility model belongs to the technical field of septic tanks, and particularly relates to a combined septic tank. Background Art

[0002] Patent Application No. 202322121290.2 discloses a combined septic tank, which includes a first septic tank, a second septic tank, a viewing window, stirring blades and crushing knives, etc. By installing the crushing knives, the added garbage and feces first pass through the crushing knives inside the feed pipe for crushing. A connecting rod is installed at the upper end of the crushing knife, and a transmission belt is sleeved outside the connecting rod. The main rod rotates to drive the connecting rod to rotate, driving the crushing knife to rotate rapidly to crush the garbage. A stirring rod is installed inside the second septic tank, a turntable is installed at the upper end of the stirring rod, and a plurality of stirring rods are installed at the lower end of the turntable to accelerate the mixing inside the septic tank, accelerate the treatment effect of feces and garbage, and improve the treatment efficiency.

[0003] Although the above treatment solution for the septic tank can perform crushing and mixing, in use, there are the following defects: First, in the crushing process, mainly relying on the mutual impact between the crushing knife and the garbage for cutting and crushing, but the garbage is easily pushed by the rotating crushing knife to rotate synchronously, resulting in a weak impact force between the garbage and the crushing knife, causing low crushing efficiency. Secondly, in the mixing process, the stirring blades can only rotate around the motor shaft along with the stirring rod, but cannot rotate around the axis of the stirring rod, resulting in a single stirring method, a long required mixing time, and a reduced mixing efficiency.

[0004] Therefore, it is necessary to locally optimize and improve the crushing and mixing methods of the above treatment solution for the septic tank. Summary of the Utility Model

[0005] To solve the problems existing in the prior art, the utility model provides a combined septic tank. The crushing knives on two crushing rods rotate in a staggered and opposite manner, enhancing the impact force between the garbage and the crushing knives, enabling the garbage to be cut and crushed by the crushing knives faster, and improving the crushing efficiency. The stirring blades can not only rotate around the rotating shaft along with the stirring rod, but also rotate around the axis of the stirring rod, increasing the stirring effect inside the second septic tank, shortening the required mixing time, and improving the mixing efficiency.

[0006] To achieve the above object, the utility model provides the following technical solutions:

A plurality of stirring rods are arranged inside the second septic tank, and stirring blades are symmetrically installed on both sides of the stirring rods. The top of the inner cavity of the first septic tank is fixedly connected with a wire mesh frame, an opening is arranged at the top of the wire mesh frame, the bottom of the feed inlet corresponds to the opening of the wire mesh frame, the number of the crushing rods is two and they are located inside the wire mesh frame, the crushing knives on the two crushing rods are distributed up and down in a staggered manner, the top of the crushing rod is rotationally connected with the top of the first septic tank, the top ends of the two crushing rods both extend above the first septic tank and are fixedly sleeved with a first gear, the two first gears are meshed with each other, the top of the inner cavity of the second septic tank is fixedly connected with an internal gear, the top of the second septic tank is rotationally connected with a rotating shaft, the bottom end of the rotating shaft passes through the middle of the internal gear and is fixedly connected with a turntable, the top ends of the plurality of stirring rods are all rotationally connected with the turntable, the top ends of the plurality of stirring rods are all fixedly sleeved with a second gear, and the plurality of second gears are all meshed with the internal gear. A driving mechanism is jointly installed above the first septic tank and the second septic tank.

[0008] Further, the driving mechanism comprises a motor, a pulley and a belt. The motor is arranged above the second septic tank, the output shaft of the motor is fixedly connected with the top end of the rotating shaft, a pulley is fixedly sleeved on one of the crushing rods and the rotating shaft, and the two pulleys are connected through the belt in a transmission manner.

[0009] Further, brackets are fixedly connected to both the left and right sides of the motor, and the bottom of the brackets is fixedly connected with the second septic tank.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. Through the two crushing rods and the crushing knives arranged in a staggered manner, and in cooperation with the first gears, the two crushing rods rotate in opposite directions, so that the crushing knives on the two crushing rods rotate in a staggered and opposite manner. When the garbage is pushed by the crushing knives on one side, the crushing knives on the other side can impact and cut the garbage, enhancing the impact force between the garbage and the crushing knives, enabling the garbage to be cut and crushed by the crushing knives more quickly, and improving the crushing efficiency.

[0013] 2. Through the cooperation of the internal gear and the second gears, when the rotating shaft drives the plurality of stirring rods on the turntable to rotate, the stirring blades can not only rotate around the rotating shaft along with the stirring rods, but also rotate around the axis of the stirring rods, increasing the stirring effect inside the second septic tank, shortening the required time for mixing, and improving the mixing efficiency.

[0014] 3. The driving mechanism composed of a motor, a pulley and a belt enables the entire device to only use one motor, reducing the number of motors required and the cost of purchasing motors. The bracket facilitates fixing the position of the motor. By enclosing the internal gear in the turntable, it is convenient to protect the internal gear and the second gear, making it not easily splashed by the agitated fecal water and avoiding the phenomenon of the gear being corroded by fecal water, thus improving its service life.

The second gear 13 drives the stirring rod 6 to rotate. Furthermore, the stirring blades 7 rotate around the stirring rod 6 as the axis. Thus, when the rotating stirring blades 7 move in the trajectory of rotating around the rotating shaft 11, the stirring effect on this trajectory area is accelerated until the mixing is completed.
