Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage recycling, in particular to a surface sewage recycling and cyclic utilization system. Background Art
[0002] Although the grinding efficiency can be improved when using a ball mill for cement grinding, the cement particles are too concentrated, so the water demand is also large. In order to ensure the production quality of cement products, the water supply pipeline usually needs to supply a large amount of water resources.
[0003] A large amount of sewage will be generated during the grinding stage. This type of sewage includes solid particles and mud suspension. The traditional sewage recovery system simply discharges the sewage into a reservoir and uses the sedimentation of sewage and the filter in the reservoir to achieve solid-liquid separation. However, due to the high turbidity of the sewage, the cement on the filter plate will become agglomerated and adhere to the sieve holes after the filter has been used for a period of time, affecting the subsequent filtration of sewage and ultimately leading to the recycling of sewage. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a surface sewage recycling and cyclic utilization system.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A surface sewage recycling system comprises a water storage sedimentation tank, wherein a sewage inlet and a sewage outlet are respectively arranged on both sides of the water storage sedimentation tank, and a rotating column and two guide rods are respectively arranged on the front and rear sides of the water storage sedimentation tank;
[0007] The guide rods on the same side are symmetrically arranged on the upper and lower sides of the rotating column, and the rotating column is slidably equipped with a sliding block, and the surface of the sliding block facing the middle rotating column is provided with a sliding ball;
[0008] The surface of the rotating column is provided with a spiral closed guide groove, and the sliding beads on the upper and lower sides are respectively built into the guide groove and slide along the guide groove;
[0009] The two sliding beads on the same side are located opposite to each other, and the two sliding beads on different sides but at the same height are connected by a scraper.
[0010] The water storage sedimentation tank is provided with two layers of filter plates inside and are respectively designed as a lower filter screen plate and an upper filter screen plate. The upper scraper scrapes the surface of the upper filter screen plate, and the lower scraper scrapes the surface of the lower filter screen plate.
[0011] In a preferred technical solution, sewage is discharged into a water storage sedimentation tank through a sewage inlet through a self-built recycling ditch. The sewage outlet is externally connected to a sewage purification tank, and the sewage is purified by the purification tank and circulated twice.
[0012] In a preferred technical solution, a transmission motor is arranged on the inner wall of the water storage sedimentation tank, and a transmission shaft arranged at the output end of the transmission motor is connected to the rotating column in a coaxial rotational manner.
[0013] In a preferred technical solution, the scraper located on the upper layer and the scraper located on the lower layer are both fixedly installed in an oblique manner.
[0014] In a preferred technical solution, a lower layer drain pipe and an upper layer drain pipe are provided on the inner wall of the water storage sedimentation tank, the lower layer drain pipe corresponds to the lower layer filter mesh plate, and the upper layer drain pipe corresponds to the upper layer filter mesh plate, and the upper layer drain pipe and the lower layer drain pipe are respectively provided with a pump body for sucking dirt from the corresponding layer plates.

[0016] In a preferred technical solution, the lower filter screen plate and the upper filter screen plate are evenly distributed with dense filter mesh holes, and the filter mesh number of the upper filter screen plate is smaller than the filter mesh number of the lower filter screen plate.
[0017] The beneficial effects of the utility model are:
[0018] The sewage circulation system proposed in this scheme solves the problem that the filter plate of the water storage tank lacks necessary scraping equipment, resulting in untimely sewage filtration and affecting sewage recycling. A scraper that can move back and forth is added to the filter screen plate of the water storage sedimentation tank. The scraper can be used to quickly scrape off the impurities retained on the screen to ensure the cleanliness of the mesh, which is conducive to the continuous filtration of sewage. Finally, it can ensure that the clean sewage on the upper layer enters the purification system, and after sufficient purification, it is returned to the cement grinding process for circulation again, reducing water consumption and reducing production costs.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] In this embodiment, refer to Figure 1-3 A surface sewage recycling and utilization system includes a water storage sedimentation tank 1, with a sewage inlet 2 and a sewage outlet 3 respectively arranged on both sides of the water storage sedimentation tank 1. The sewage is discharged into the water storage sedimentation tank 1 through the sewage inlet 2 through a self-built recovery ditch, and the sewage outlet 3 is externally connected to a sewage purification tank. The sewage mixture is precipitated and separated in the water storage sedimentation tank 1, and then the upper layer of relatively clear sewage is discharged into the purification tank through the sewage outlet 3. The sewage is purified by the purification tank and is circulated for a second time to be supplied to the cement grinding process.
[0025] A rotating column 6 and two guide rods 7 are respectively arranged on the front and rear sides of the water storage sedimentation tank 1. The guide rods 7 on the same side are symmetrically arranged on the upper and lower sides of the rotating column 6. The rotating column 6 is slidably equipped with a sliding block 9. The surface of the sliding block 9 facing the middle rotating column 6 is provided with a sliding ball 10. Figure 1 As shown, a spiral closed guide groove 8 is provided on the cylindrical surface of the rotating cylinder 6 , and the sliding beads 10 on the upper and lower sides are respectively built into the guide groove 8 and slide along it.
[0026] A transmission motor 12 is arranged on the inner wall of the water storage sedimentation tank 1, and a transmission shaft arranged at the output end of the transmission motor 12 is connected to the rotating column 6 in a coaxial rotational manner. By controlling the transmission motor 12 to start, the rotating column 6 is rotated. Since the two upper and lower sliding beads 10 are both built into the guide groove 8 on the surface of the rotating column 6, the sliding beads 10 and the sliding block 9 will maintain synchronous back and forth translational motion.
[0027] The two sliding beads 10 on the same side are positioned opposite to each other, and the two sliding beads 10 on different front and rear sides but at the same height are connected by a scraper 11. It should be specifically noted that the scraper 11 on the upper layer and the scraper 11 on the lower layer are both fixedly installed obliquely.
[0028] Two layers of filter plates are arranged inside the water storage sedimentation tank 1 and are respectively designed as a lower filter screen plate 4 and an upper filter screen plate 5. The scraper 11 located at the upper side scrapes the surface of the upper filter screen plate 5, and the scraper 11 located at the lower side scrapes the surface of the lower filter screen plate 4.
[0029] Sewage continuously enters the sewage storage sedimentation tank 1. When the specified liquid level is reached, the water intake is stopped. The sewage is statically precipitated and gradually separated in the storage sedimentation tank 1. The upper layer is sewage with lower turbidity, and the sewage with higher turbidity gradually moves to the lower layer and gradually passes through the upper filter mesh plate 5 and the lower filter mesh plate 4 at the bottom. The particulate matter is respectively retained on the mesh plates to form granular impurities. After the separation effect is more obvious, the scraper 11 can be translated from one side to the other. During the translation process, the dirt on the layer plate is synchronously scraped to one side of the mesh plate.
[0030] The inner wall of the water storage sedimentation tank 1 is provided with a lower layer drain pipe 13 and an upper layer drain pipe 14. The lower layer drain pipe 13 corresponds to the lower layer filter screen plate 4, and the upper layer drain pipe 14 corresponds to the upper layer filter screen plate 5. Pump bodies for sucking the dirt from the corresponding layers are respectively provided in the upper layer drain pipe 14 and the lower layer drain pipe 13. After the dirt is pushed aside, the dirt can be sucked out by using the lower layer drain pipe 13 and the upper layer drain pipe 14. The scraper 11 is returned to the initial position and can be used for the next sewage separation treatment.
[0031] Finally, it should be added that a clearing pipe 15 is provided at the bottom of the water storage sedimentation tank 1. The clearing pipe 15 is used to empty the water storage sedimentation tank 1 and can be used to clean the tank wall.
[0032] In addition, dense filter mesh holes 16 are evenly distributed on the lower filter screen plate 4 and the upper filter screen plate 5, and the filter mesh number of the upper filter screen plate 5 is smaller than the filter mesh number of the lower filter screen plate 4. The different mesh numbers of the upper and lower screen plates can be used to screen out debris with different particle sizes, which is also beneficial for classified recycling, reducing the difficulty of subsequent manual secondary separation of impurities and facilitating operation.
[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
