[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] In the description of the present utility model, unless otherwise specified, "multiple" means two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] like Figure 1-4 As shown, a concrete waste slurry recycling device provided by an embodiment of the utility model includes a waste slurry tank 1 and a stirring assembly 2, the stirring assembly 2 includes a stirring rod 24 and a driving part for driving the stirring rod 24 to rotate, the stirring rod 24 is arranged inside the waste slurry tank 1, and also includes an inflation assembly 3, a gas channel is arranged in the stirring rod 24, the air inlet end of the gas channel is connected to the output end of the inflation assembly 3, and the air outlet end of the gas channel is arranged at the lower end of the stirring rod 24.

[0028] Specifically, when the device is in use, the driving unit drives the stirring rod 24 to rotate, stirs the slurry in the waste slurry tank 1, and prevents the waste slurry from settling, which affects the effect of reuse. At the same time, the inflation component 3 introduces gas to the lower part of the waste slurry tank 1 through the gas channel arranged in the stirring rod 24. The introduced air can generate bubbles in the slurry in the waste slurry tank 1 and destroy the original flow law of the slurry in the waste slurry tank 1 when it is stirred, so that the slurry concentration in various places in the waste slurry tank 1 is kept uniform. Optionally, the inflation component 3 uses an air pump as an air source, and connects the air pump to the stirring rod 24 through a pipeline. The driving unit adopts The existing driving structure can be directly applied without further elaboration. It should be noted that a slurry concentration sensor is also provided in the waste slurry tank 1, which can detect the concentration of the slurry in the waste slurry tank 1. The slurry concentration sensor is a prior art and can be directly applied without further elaboration, so as to control the amount of cement added to the concrete mixing pot when the waste slurry is used, thereby controlling the concrete strength within the standard range. Another function of the stirring component 2 is that when the slurry concentration in the waste slurry tank 1 is not enough, cement needs to be added for mixing. The stirring component 2 can promote the mixing efficiency of cement and the original slurry in the waste slurry tank 1.

[0029] In this embodiment, gas is introduced into the lower part of the waste pulp tank 1 through the stirring rod 24, so that bubbles are generated in the waste pulp tank 1, and the introduced gas can change the flow pattern of the slurry as it is stirred by the stirring rod 24, thereby improving the stirring effect of the slurry, reducing the concentration difference of the slurry at different places, and improving the effect of slurry reuse.

[0030] Furthermore, an upper cover 13 is installed on the upper part of the waste pulp tank 1 , and the upper cover 13 completely covers the opening of the waste pulp tank 1 . A feed pipe 11 and a discharge pipe 12 are fixedly connected to the outer wall of the waste pulp tank 1 .

[0031] Specifically, by setting an upper cover 13 on the upper part of the waste slurry tank 1, the waste slurry tank 1 is sealed. During use, sand, gravel or garbage cannot enter the waste slurry tank 1, ensuring that the waste slurry is not contaminated. In specific implementation, a temporary storage pit can be set next to the waste slurry tank 1 to temporarily store the waste slurry from cleaning the tank truck and to separate the slurry and gravel to prevent the gravel from entering the waste slurry tank 1. A sewage pump is set to pump the waste slurry in the temporary storage pit into the waste slurry tank 1 for storage. As for the utilization of the waste slurry, a water pump can be set at the discharge pipe 12 to extract the slurry into the concrete mixing pot.

[0032] Furthermore, the driving unit includes a sun gear 21, a planetary gear 22 and an inner ring gear 23 arranged in the upper cover 13, the inner ring gear 23 is fixed to the inner wall of the upper cover 13, the sun gear 21 and the planetary gear 22 are rotatably installed in the upper cover 13 through the planetary carrier, the inner ring gear 23 is coaxially arranged with the sun gear 21, the planetary gear 22 is arranged between the sun gear 21 and the inner ring gear 23, and the planetary gear 22 is meshed with the sun gear 21 and the inner ring gear 23 at the same time, the stirring rod 24 is arranged in a one-to-one correspondence with the planetary gear 22, and the stirring rod 24 is fixed to the corresponding planetary gear 22.

[0033] Specifically, by installing the stirring rod 24 on the planetary gear 22 and utilizing the sun gear 21 to drive the planetary gear 22 to rotate and revolve, the stirring effect of the stirring rod 24 is further enhanced, so that the waste slurry at various locations in the waste slurry tank 1 can be stirred, and the gas introduced through the gas channel can change the position of the gas introduced into the waste slurry tank 1 when the stirring rod 24 revolves, thereby further enhancing the stirring effect of the slurry in the waste slurry tank 1.

[0034] Furthermore, the inflation component 3 includes an inflation device and a disc 31 rotatably connected to the upper cover 13. The disc 31 is coaxially arranged with the sun gear 21 and is arranged above the sun gear 21. An annular groove 311 is provided on the outer wall of the disc 31. The output end of the inflation device is connected to the annular groove 311. The stirring rod 24 coincides with the rotation axis of the planetary gear 22. The upper end of the stirring rod 24 passes through the corresponding planetary gear 22 and extends to the inside of the disc 31. Sockets 312 are provided at positions corresponding to the stirring rods 24 on the disc 31. Each socket 312 is connected to the annular groove 311 through a connecting hole 313.

[0035] Specifically, the disc 31 is rotatably set in the upper cover 13, and the inflation device is connected with the annular groove 311 on the disc 31. The inflation device fills the gas into the position of the annular groove 311, and enters the insertion hole 312 through the connecting hole 313 set on the annular groove 311, and finally enters the gas channel set on the stirring rod 24, and finally enters the lower part of the waste pulp tank 1 through the gas channel, which ensures that the gas can be filled into the lower part of the waste pulp tank 1 through the gas channel set in the stirring rod 24, and there is no problem of pipe entanglement. It should be noted that dynamic sealing is adopted between the disc 31 and the upper cover 13, and dynamic sealing is adopted between the upper end of the stirring rod 24 and the position of the insertion hole 312 on the disc 31.

[0036] Furthermore, the upper portion of the stirring rod 24 is in a right-angled Z shape.

[0037] Specifically, the upper portion of the stirring rod 24 is arranged in a right angle Z shape, such as Figure 2 As shown, during the use of the device, the self-rotation of the stirring rod 24 can also have a certain degree of stirring effect on the slurry.

[0038] Furthermore, the lower portion of the stirring rod 24 is in the shape of an inverted funnel.

[0039] Specifically, by configuring the lower portion of the stirring rod 24 to be funnel-shaped, the diameter of the end of the gas passage is increased, thereby reducing the possibility of slurry settling and causing blockage of the gas passage when the stirring assembly 2 is shut down.

[0040] Furthermore, the driving unit also includes a driving motor 25 and a reducer fixed to the top of the upper cover 13, the output end of the driving motor 25 is connected to the input end of the reducer, and the output end of the reducer is coaxially connected to the sun gear 21 through a rotating shaft.

[0041] Furthermore, the feed pipe 11 and the discharge pipe 12 are respectively arranged on both sides of the waste tank, and the feed pipe 11 is arranged on the upper part of the waste tank, and the discharge pipe 12 is arranged on the lower part of the fertilizer pipe.

[0042] Specifically, the feed pipe 11 and the discharge pipe 12 are separately arranged to prevent the slurry entering through the feed pipe 11 from being pumped away by the water pump arranged at the discharge pipe 12 before being evenly mixed, thereby affecting the strength of the concrete.

[0043] Furthermore, stirring blades 241 are arranged in a circumferential array on the outer wall of the stirring rod 24 .

[0044] Furthermore, the stirring blade 241 is plate-shaped and is tilted, and the vertical plane where the long side of the stirring blade 241 is located is tangent to the rotation trajectory of the stirring rod 24 .

[0045] Specifically, Figure 2As shown, by tilting the stirring blade 241, during the rotation and revolution of the stirring blade 241 along with the stirring rod 24, the slurry in the waste slurry tank 1 can have a tendency to flow in a vertical direction, thereby promoting the mixing of the upper slurry and the lower slurry in the waste slurry tank 1, and further improving the slurry mixing effect in the waste slurry tank 1.

[0046] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
