[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Embodiment 1

[0024] However, the existing part of the settling device has low mixing efficiency of slurry and flocculant, which affects the downward settlement of particulate matter, and manual stirring is required, which is time-consuming and labor-intensive, resulting in low production efficiency. Moreover, due to the small size of the slurry outlet, the slurry outlet is prone to blockage. Please refer to Figs. 1-3 The present application provides an aluminum oxide settling combined device, which solves the technical problem of easy blockage of settled slurry. The device comprises a support frame 1 as a support base, a slurry anti-blocking mechanism 2 for preventing slurry blockage is arranged on the support frame 1, and an accelerated precipitation mechanism 3 for accelerating the precipitation of slurry is arranged on the support frame 1. The raw material is settled by the accelerated precipitation mechanism 3, the settled slurry in the raw material is filtered by the slurry anti-blocking mechanism 2, and power is provided to the accelerated precipitation mechanism 3.

[0025] In order to prevent the slurry from blocking and make the discharge of the slurry more smooth, the slurry anti-blocking mechanism 2 comprises a filter tank 201 fixedly connected to one side of the support frame 1, a bottom layer filter screen 202 fixedly connected to the inner top end of the filter tank 201, a top tank 203 movably connected to the top end of the filter tank 201, a top layer filter screen 204 fixedly connected to the inner bottom end of the top tank 203, a anti-blocking brush rod 205 rotatably connected to the inner side of the top tank 203, and a slurry discharge groove 208 formed in the bottom end of the filter tank 201, the bottom layer filter screen 202 and the top layer filter screen 204, a limiting seat 210 spirally connected to the inner side of the slurry discharge groove 208, and the brush surfaces of the anti-blocking brush rod 205 are in close contact with the top end surface of the top layer filter screen 204.

[0026] In order to provide power to the slurry anti-blocking mechanism 2 and the accelerated precipitation mechanism 3, a transmission motor 206 is installed on one side of the top end of the top tank 203 through a base, and a driving bevel gear 207 is connected to the transmission end of the transmission motor 206.

[0027] In order to make the filtered water more smooth when discharging, the inner bottom end of the filter tank 201 is conical, and a drain pipe 209 is connected to the bottom of one end of the outer side of the filter tank 201.

[0028] First, the accelerated precipitation mechanism 3 will transport the raw materials after settling to the inside of the top tank 203, during which the raw materials will be filtered by the top filter screen 204 and the bottom filter screen 202 in turn, and the top surface of the top filter screen 204 will accumulate slurry after a long period of filtering. At this time, the transmission motor 206 drives the driving bevel gear 207 connected to its transmission end to rotate, and the driving bevel gear 207 drives the anti-blocking brush rod 205 engaged with it to rotate, and the anti-blocking brush rod 205 brushes the surface of the top filter screen 204, preventing the slurry on the surface of the top filter screen 204 from being blocked. During the brushing of the anti-blocking brush rod 205, the slurry that leaks through the top filter screen 204 will be isolated again by the bottom filter screen 202, ensuring the cleanliness of the filtered raw materials. The filtered raw materials will eventually flow into the filter tank 201, and will eventually be discharged through the drain pipe 209 connected to the outside of the filter tank 201. After the filtering operation is completed, the operator can unscrew the limiting seat 210 connected to the bottom end of the filter tank 201, the bottom filter screen 202 and the top filter screen 204, at which time the slurry on the top surface of the bottom filter screen 202 and the top filter screen 204 will be discharged through the slurry discharge groove 208.

[0029] Example 2

[0030] On the basis of example 1, example 1 solves the technical problem of easy blockage of the settling slurry, but there is still the problem of long coagulation time of the flocculating agent. In combination with Figs. 1-3 As shown in the figure, the specific implementation process is as follows: in order to accelerate the sedimentation speed of the raw materials by stirring. The accelerated precipitation mechanism 3 includes a precipitation tank 301 fixedly connected to the other side inside the support frame 1, a stirring rod 302 rotatably connected to the inside of the precipitation tank 301, a driven bevel gear 304 rotatably connected to one side of the top end of the precipitation tank 301 and connected to the driving bevel gear 207, and the anti-blocking brush rod 205 and the stirring rod 302 are both fixedly connected to the engagement bevel gear 303 engaged with the driven bevel gear 304.

[0031] In order to transmit the precipitated raw materials to the slurry anti-blocking mechanism 2. The precipitation tank 301 is provided below the water pump 305, the water pump 305 is connected to the communication pipe 306, the communication pipe 306 is extended to the inside of the top tank 203 through the top end of the top tank 203, and the water inlet end of the water pump 305 is extended to the inside bottom end of the precipitation tank 301, and the top end of the precipitation tank 301 is connected to the feed pipe 307.

[0032] The power transmitted by the slurry anti-blocking mechanism 2 drives the stirring rod 302 to rotate, stirring the raw material to which the flocculant has been added in the sedimentation tank 301, which can accelerate the effect of the flocculant and thus accelerate the sedimentation efficiency. The raw material in the sedimentation tank 301 is extracted by the water pump 305 and transmitted to the slurry anti-blocking mechanism 2 through the connecting pipe 306, so that the settled raw material can be filtered in time.
