Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recovery devices, in particular to a wastewater recovery device for concrete production. Background Art

[0002] In the traditional production process of the concrete industry, a large amount of wastewater is generated by direct discharge of wastewater from production equipment and flushing of sites. If it is discharged without treatment, it will cause serious damage to the natural environment. The current equipment for treating this type of wastewater can only process a small amount at a time, and the efficiency is not high. In addition, it is difficult to recover the larger stones mixed in the wastewater after precipitation, which will lead to a waste of resources.

[0003] The application number is 202122986023.2. A wastewater recovery device for concrete production is mentioned in the patent with patent authorization announcement number CN213555813U. A wastewater recovery device for concrete production includes a placement bucket and a cover plate. The cover plate is fixed to the top of the placement bucket. A water inlet pipe is fixedly connected to one end of the top of the cover plate. A support frame is fixed to the top of the inner cavity of the placement bucket. A plurality of blocks are fixed at equal arcs and intervals on the top of the support frame. A filtering mechanism is arranged inside the support frame. A stirring mechanism is arranged at the bottom end of the cover plate. A sponge is fixed to the middle of the inner cavity of the placement bucket. This patent is provided with a placement bucket, and a foot brake universal wheel is provided at the bottom of the placement bucket, so that the device can be moved without the limitation of being unable to change the position according to the position of the concrete production equipment. A support frame is provided, and a filter bucket is placed on the top of the support frame. Waste water enters the interior of the filter bucket through the water inlet pipe. During use, this patent needs to frequently open the cover to take out the filter bucket to clean the stones.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a wastewater recovery device for concrete production, comprising a recovery tank body 1, a stirring device 2 is arranged inside the recovery tank body 1, the stirring device 2 comprises a filter screen 201, the number of the filter screen 201 is two groups, the filter screen 201 is in a fan-shaped structure, a rotating shaft 202 is arranged at the connection of the two groups of filter screens 201, a sleeve 203 is fixedly sleeved on the outer wall of the rotating shaft 202, and stirring blades 204 are distributed in a circular shape on the outer wall of the sleeve 203, a partition 3 is fixedly installed below the stirring device 2 inside the recovery tank body 1, and a support shaft 5 is fixedly installed at the connection of the four groups of partitions 3.

[0022] In this embodiment: four groups of partitions 3 divide the recovery tank body 1 into two wastewater chambers and two waste residue chambers, wherein the wastewater chamber is located at the front and back sides of the recovery tank body 1, and the waste residue chamber is located at the left and right sides of the recovery tank body 1, and the size of the filter screen 201 is adapted to the wastewater chamber.

[0023] When used specifically, the partition 3 can divide the internal space of the recovery tank 1, so that there is no need to perform manual impurity removal steps during the recovery process of the wastewater used in concrete production.

[0024] In this embodiment: the bottom of the rotating shaft 202 is rotatably connected to the support shaft 5 through a bearing, the inner diameter of the sleeve 203 matches the outer diameter of the rotating shaft 202, the number of the stirring blades 204 is several groups, and the stirring blades 204 are evenly distributed along the circumference of the outer wall of the sleeve 203.

[0025] When used specifically, the four groups of stirring blades 204 can cooperate with the partition plate 3 to intercept the two ends of the filter screen 201, thereby reducing the phenomenon that the waste water is recycled in the tank body 1 and flows into the impurity chamber.

[0026] In this embodiment: leakage holes 4 are opened on the outer walls of both sides of the recovery tank body 1, the leakage holes 4 are stepped, and the leakage holes 4 pass through the waste residue cavity.

[0027] When used specifically, the leakage hole 4 can automatically discharge the wastewater impurities in the impurity chamber by gravity, thus saving the steps of manual cleaning.

[0028] In this embodiment: an upper cover plate 6 is fixedly installed on the top of the recovery tank body 1, a driving motor 7 is fixedly installed at the center of the upper surface of the upper cover plate 6, the output end of the driving motor 7 is fixedly connected to the rotating shaft 202, and a wastewater inlet pipe 8 is fixedly installed inside the upper cover plate 6 at the front and rear sides of the driving motor 7, and the wastewater inlet pipe 8 and the waste liquid chamber are distributed in an upper and lower correspondence.
