Description

Technical Field

[0001] This utility model belongs to the field of concrete technology, specifically relating to a rapid separation device for concrete wastewater and slurry. Background Technology

[0002] Concrete wastewater mainly originates from cleaning and rinsing processes during concrete production, transportation, and construction. Its treatment and recycling are crucial for environmental management in the industry. The treatment of concrete wastewater requires the separation of particles to prevent direct discharge and environmental pollution. However, existing concrete wastewater and slurry separation devices cannot effectively clean the residual wastewater inside the separation tank after treatment, resulting in generally limited practical effectiveness.

[0003] A patent with publication number CN221720665U discloses a wastewater recycling device for concrete production, including a separation box. The lower end of the separation box is symmetrically and inclinedly equipped with a stone-passing pipe and a filter sand pipe. An electrically controlled valve is provided between the stone-passing pipe and the separation box, and a filter sand screen is provided between the filter sand pipe and the separation box. The separation box adopts a semi-circular structure, and a rotating rod is rotatably installed on the internal axis of the separation box. The outer wall of the rotating rod is connected to a scraper through a support rod, and the scraper is in close contact with the inner wall of the separation box.

[0004] However, the above method cannot directly clean the inside of the separator; it can only be cleaned by filling the inlet with water. During this process, the sand and gravel filter at the bottom of the separator continuously drains water, preventing other parts of the separator from being cleaned effectively and promptly, resulting in mediocre performance. Furthermore, the scraper in this method can only work on the curved inner wall of the separator, failing to clean the top inner wall, which is a significant limitation. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a rapid separation device for concrete wastewater and slurry.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rapid separation device for concrete wastewater and slurry includes a main body, a separation cylinder fixedly embedded above the main body, and a second motor fixedly mounted on the outer surface of the separation cylinder. The output shaft of the second motor extends rotatably into the main body and is fixedly mounted with a water pipe, which is rotatably positioned inside the separation cylinder in a horizontal direction. The end of the water pipe not connected to the output shaft of the second motor extends rotatably out of the separation cylinder and is rotatably connected to a connecting pipe, which is fixedly connected to an external water supply device. A plurality of nozzles are fixedly connected to the outer surface of the water pipe, and the nozzles are arranged in a circular array along the central axis of the water pipe.

[0008] Furthermore, a rotating sleeve and a rotating plate are fixedly fitted on the outer surface of the water pipe, and the rotating sleeve and the rotating plate are symmetrically arranged on the inner walls of both sides of the separation cylinder; a scraper is fixedly installed between the rotating sleeve and the rotating plate, and a second rotating shaft is rotatably installed, with a brush roller fixedly fitted on the outer surface of the second rotating shaft.

[0009] Furthermore, a toothed ring and a sealing ring are fixedly installed on the inner wall of the separating cylinder near the rotating sleeve. Both the toothed ring and the sealing ring are coaxially arranged with the separating cylinder. The rotating sleeve and the sealing ring are adapted to each other and the two are sealed and rotated together. One end of the second rotating shaft rotates through the rotating sleeve and is fixedly provided with a gear. The gear meshes with the toothed ring for transmission.

[0010] Furthermore, a filter screen is fixedly installed at the bottom of the separation cylinder, and the brush roller and scraper are in close contact with the filter screen. A second discharge plate is provided below the filter screen, and the second discharge plate is fixedly connected to the main body. A discharge valve is installed on the outer surface of the separation cylinder, and a first discharge plate is installed on the main body. The first discharge plate is connected to the discharge valve.

[0011] Furthermore, a first motor is fixedly installed on the outer surface of the main body, the output shaft of the first motor extends rotatably into the main body and a first rotating shaft is fixedly installed therein, the other end of the first rotating shaft rotatably passes through the second discharge plate and is rotatably connected to the inner wall of the main body; a plurality of striking plates are fixedly installed on the outer surface of the first rotating shaft located inside the second discharge plate, and the plurality of striking plates are all engaged with the filter screen for striking.

[0012] This application has the following beneficial effects:

[0013] 1. By placing water pipes inside the separator, and using several nozzles connected to the outer surface of the water pipes, the inside of the separator can be directly rinsed, ensuring that all parts of the separator are rinsed in a timely and effective manner, resulting in better practical performance.

[0014] 2. The second motor can drive the water pipe to rotate, causing several nozzles to rotate synchronously, thereby more thoroughly rinsing the inner wall of the separator. In addition, the second motor will also drive the scraper and brush roller to rotate synchronously, thereby cleaning the inner wall of the separator more effectively, preventing sand and gravel particles from adhering to the inner wall of the separator, and improving the cleaning effect of the inner wall of the separator.

[0015] 3. The brush roller revolves around the central axis of the separation cylinder while also rotating on its own axis, thereby further improving the cleaning effect on the inner wall of the separation cylinder.

[0016] 4. The rotation of the scraper and brush roller can scrape away the accumulated material on the filter screen, preventing the filter screen surface from becoming clogged. At the same time, the first motor can drive the striking plate to repeatedly strike the bottom of the filter screen, causing the filter screen to vibrate, further preventing the filter screen surface from becoming clogged.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: a rapid separation device for concrete wastewater and slurry includes a main body 1, a separation cylinder 2 is fixedly embedded in the top of the main body 1, a feed inlet 3 is fixedly connected to the top of the separation cylinder 2, a second motor 7 is fixedly installed on the outer surface of the separation cylinder 2, and a water pipe 16 is rotatably arranged inside the separation cylinder 2. The water pipe 16 is arranged in a horizontal direction and coaxial with the separation cylinder 2.

[0025] The output shaft of the second motor 7 extends into the separator 2 and is fixedly connected to one end of the water pipe 16. The other end of the water pipe 16 extends out of the separator 2 and is rotatably connected to the connecting pipe 20. The connecting pipe 20 is fixedly connected to an external water supply device (not shown in the figure).

[0026] Among them, a number of nozzles 161 are fixedly connected to the outer surface of the water pipe 16, and the nozzles 161 are distributed in a circular array along the center of the water pipe 16.

[0027] A rotating sleeve 10 and a rotating plate 12 are fixedly fitted onto the outer surface of the water pipe 16. The rotating sleeve 10 and the rotating plate 12 are symmetrically arranged on the inner walls of both sides of the separation cylinder 2. A scraper 11 is fixedly installed between the rotating sleeve 10 and the rotating plate 12, and a second rotating shaft 21 is rotatably installed. A brush roller 14 is fixedly fitted onto the outer surface of the second rotating shaft 21. Both the brush roller 14 and the scraper 11 are in close contact with the inner wall of the separation cylinder 2, and the scraper 11 is arranged in a V-shape.

[0028] A gear ring 19 and a sealing ring 18 are fixedly installed on the inner wall of the separating cylinder 2 near the rotating sleeve 10. Both the gear ring 19 and the sealing ring 18 are coaxially arranged with the separating cylinder 2. The rotating sleeve 10 is adapted to the sealing ring 18 and the two are sealed and rotated together. One end of the second rotating shaft 21 rotates through the rotating sleeve 10 and is fixedly equipped with a gear 17. The gear 17 meshes with the gear ring 19 for transmission.

[0029] A filter screen 15 is fixedly installed at the bottom of the separator cylinder 2. The brush roller 14 and the scraper 11 slide in close contact with the filter screen 15. A second discharge plate 5 is provided below the filter screen 15, and the second discharge plate 5 is fixedly connected to the main body 1. A discharge valve 13 is installed on the outer surface of the separator cylinder 2, and a first discharge plate 4 is installed on the main body 1. The first discharge plate 4 is connected to the discharge valve 13.

[0030] In addition, a first motor 6, which is a servo motor, is fixedly installed on the outer surface of the main body 1. The output shaft of the first motor 6 extends rotatably into the main body 1 and is fixedly mounted on a first rotating shaft 8. The other end of the first rotating shaft 8 rotatably passes through the second discharge plate 5 and is rotatably connected to the inner wall of the main body 1. Among them, several striking plates 9 are fixedly mounted on the outer surface of the first rotating shaft 8 inside the second discharge plate 5, and the striking plates 9 are all engaged with the filter screen 15 in a striking action.

[0031] Working principle: When in use, concrete wastewater and waste slurry are added into the separation cylinder 2 through the feed inlet 3, so that the water introduced by the external water supply device is transported to the nozzle 161 through the connecting pipe 20 and the water pipe 16 in sequence and sprayed out. The high-pressure water flow sprayed out by the nozzle 161 can accelerate the separation of concrete wastewater and waste slurry.

[0032] During this period, the second motor 7 is started, and the output shaft of the second motor 7 drives the water pipe 16 to rotate. The water pipe 16 drives several nozzles 161 to rotate around the central axis of the separation cylinder 2, thereby improving the flushing effect on concrete wastewater and further accelerating the separation speed of concrete wastewater and waste slurry.

[0033] Meanwhile, the rotation of the water pipe 16 causes the scraper 11 and brush roller 14 to rotate around the central axis of the separating cylinder 2. During the rotation of the scraper 11 and brush roller 14, they agitate the sand and gravel particles on the filter screen 15, thereby preventing the sand and gravel particles from clogging the filter screen 15. In addition, while the brush roller 14 revolves around the central axis of the separating cylinder 2, it also rotates on its own axis through the meshing of the gear 17 and the gear ring 19, thereby further improving the agitation effect on the sand and gravel particles on the filter screen 15 and preventing the sand and gravel particles from clogging the filter screen 15.

[0034] During this period, the first motor 6 is started, and the output shaft of the first motor 6 drives the first rotating shaft 8 to rotate forward and backward at a certain angle, so that the striking plate 9 intermittently strikes the second discharge plate 5 and the filter screen 15, causing the filter screen 15 to vibrate slightly, further preventing sand and gravel particles from clogging the filter screen 15.

[0035] The wastewater filtered through filter screen 15 will be discharged through the second discharge plate 5, while the sand and gravel particles will remain in the separation cylinder 2 for subsequent operations. After the wastewater in the separation cylinder 2 has been filtered, the discharge valve 13 will be opened, and the V-shaped scraper 11 will discharge the sand and gravel particles through the first discharge plate 4.

[0036] When the inside of the separator 2 needs to be cleaned, simply start the second motor 7. Water supplied by the external water supply device can directly rinse the inside of the separator 2, ensuring that all parts of the separator 2 are rinsed in a timely and effective manner, resulting in better practical performance.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
