Description

Technical Field

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

[0002] Commercial concrete, or ready-mixed concrete, refers to concrete used for commercial purposes, such as concrete that can be sold or purchased. Most construction projects today use commercial concrete. Also known as ready-mixed concrete, this refers to a pre-mixed, quality-certified concrete mixture that is sold to construction companies as a commodity and then transported to the construction site for pouring. Commercial concrete centralizes the entire concrete production process, from raw material selection, mix design, admixture selection, concrete mixing, and delivery, from individual construction sites to a mixing station. The station then centrally manages and supplies the finished products to construction companies as commercial products. Wastewater generated during the concrete production process requires recycling and treatment.

[0003] Prior art publication number CN215288242U discloses a wastewater recovery system for concrete production, comprising a sedimentation tank, a collection hopper, and a filter plate. The collection hopper is reversibly mounted at the upper opening of the sedimentation tank. The bottom of the collection hopper is provided with a plurality of first filter holes for retaining sand and gravel in the concrete wastewater within the collection hopper. The filter plate is horizontally arranged and liftably disposed within the sedimentation tank. The filter plate is located directly below the collection hopper, with its peripheral sidewalls abutting against the inner sidewalls of the sedimentation tank. The filter plate is provided with a plurality of second filter holes for filtering and retaining sediment in the concrete wastewater. The sedimentation tank is provided with a water inlet hose extending into the collection hopper. This system facilitates the separation and recovery of sand and gravel from concrete wastewater, thereby improving the recycling rate of concrete wastewater.

[0004] However, when the above device is filtering sediment, the sediment in the wastewater accumulates on the filter plate. Since the sediment will cause a certain obstruction to the filter holes on the filter plate, it takes a long time to settle before the wastewater can be completely filtered. The filtration efficiency is low, which causes inconvenience in use. Therefore, a wastewater recovery mechanism for commercial concrete production is proposed to solve the above problems.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] See also Figure 1-4 In this embodiment, a wastewater recovery mechanism for commercial concrete production includes a bracket 1, a filter box 2 is fixedly installed on the top of the bracket 1, a drain pipe 3 is fixedly installed on the bottom of the filter box 2, a cover plate 4 is provided on the upper part of the filter box 2, and a filter plate 5 is provided on the lower side of the cover plate 4.

[0027] In this embodiment, a first lifting assembly is provided between the cover plate 4 and the filter box 2, and the first lifting assembly includes a fixed plate 6, which is fixedly mounted on the side wall of the filter box 2, and an electric push rod 7 and a guide rod 8 are fixedly mounted on the upper side of the fixed plate 6. The output shaft of the electric push rod 7 is fixedly connected to the bottom of the cover plate 4, and a sliding sleeve 9 is movably sleeved on the outer wall of the guide rod 8, and the sliding sleeve 9 is fixedly connected to the side of the cover plate 4.

[0028] It should be noted that there are two groups of first lifting assemblies, and the two groups of first lifting assemblies are respectively located on the left and right sides of the filter box 2 .

[0029] It should be supplemented that the upper end of the guide rod 8 is fixedly connected to a limit block 10 , and the cross-sectional diameter of the limit block 10 is larger than the cross-sectional diameter of the guide rod 8 .

[0030] In this embodiment, a second lifting assembly is provided between the filter plate 5 and the cover plate 4, and the second lifting assembly includes a mounting shell 11, which is fixedly mounted on the top of the cover plate 4, and a dual-axis motor 12 is fixedly mounted inside the mounting shell 11, and shafts 13 are fixedly mounted on the output shafts on both sides of the dual-axis motor 12, and a rotating wheel 14 is fixedly mounted on the outer wall of the shaft 13, and a traction rope 15 is wound around the outer side of the rotating wheel 14, and the lower end of the traction rope 15 is fixedly connected to the filter plate 5.

[0031] It should be noted that the end of the shaft 13 away from the dual-axis motor 12 is connected to the inner wall of the mounting shell 11 through a bearing.

[0032] Example 2:

[0033] See also Figure 1-2 On the basis of embodiment 1, a sealing plate 16 is fixedly connected to the bottom of the cover plate 4. The sealing plate 16 and the filter plate 5 are both adapted to the inner wall of the filter box 2. The traction rope 15 passes through the inner side of the cover plate 4 and the sealing plate 16. When the cover plate 4 is located at the upper end of the filter box 2, the sealing plate 16 can ensure the sealing of the upper part of the filter box 2.

[0034] It should be noted that a scraper ring 17 is fixedly connected to the bottom of the sealing plate 16, and the traction rope 15 passes through the inner side of the scraper ring 17. When the traction rope 15 moves along the inner side of the scraper ring 17, the scraper ring 17 is used to clean the mud and sand attached to the traction rope 15.

[0035] The working principle of the above embodiment is:

[0036] When the utility model is in use, the electric push rod 7 is first started to drive the cover plate 4 to rise, so that the cover plate 4 opens the upper opening of the filter box 2. At this time, the dual-axis motor 12 is started to drive the shaft 13 to rotate, and drives the runner 14 to rotate, so that the runner 14 unfolds the traction rope 15 downward, thereby moving the filter plate 5 to the lower space of the filter box 2, and draining the waste water containing sediment into the filter box 2, so that it accumulates above the filter plate 5. Then, the electric push rod 7 is started again to drive the cover plate 4 to fall, and move the cover plate 4 to the upper end of the filter box 2. The sealing plate 16 is used to seal the upper opening of the filter box 2, and then the dual-axis motor is started again. The machine 12 drives the runner 14 to reel the traction rope 15 upward, thereby driving the filter plate 5 and the sediment accumulated thereon to move upward, so that the distance between the filter plate 5 and the sealing plate 16 is shortened. As the two get closer, the sediment is squeezed, thereby prompting the wastewater in the sediment to quickly pass through the filter plate 5 to flow to the bottom of the filter box 2, greatly reducing the filtration time. Subsequently, the cover plate 4 can be driven to move upward by the electric push rod 7. Since the dual-axis motor 12 drives the runner 14 to reel the traction rope 15 upward, the filter plate 5 is moved to the upper position of the filter box 2, and the staff can easily clean the sediment accumulated on the filter plate 5.
