Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sewage treatment device for a concrete mixing station. Background Art

[0002] The working principle of a concrete mixing station is to mix raw materials such as cement, sand, and stone in a certain proportion, and finally form a building material with certain strength and durability through processes such as mixing, weighing, and conveying. Since the concrete mixing station requires a large amount of water during the production process, a large amount of sewage will be generated, and the direct discharge of untreated sewage will cause serious pollution to the water body. Therefore, a sewage treatment device is needed to purify the generated sewage and reuse it in production, which can realize the recycling of water resources and improve the utilization rate of water resources. At present, in the sewage treatment process, the sewage sedimentation tank in the sewage treatment device is used to remove domestic wastewater or clean concrete equipment. Impurities and pollutants in sewage can be recycled; since most concrete mixing plants directly pass sewage into sedimentation tanks, when the sewage flows faster, the sewage will impact the sludge at the bottom of the tank, causing the suspended matter in the sludge at the bottom of the tank to float up, so a filter is needed to block the suspended matter in the sewage sedimentation tank to prevent the suspended matter from being discharged out of the outlet along with the water flow; since the water flow in the sewage sedimentation tank enters and is discharged in one direction, the water flow carries the suspended matter to the surface of the filter, causing a large amount of impurities to gradually accumulate on its surface, which will not only affect the filtering effect, but also cause the filter to become clogged, affecting the normal operation of the sewage treatment and reducing the sewage treatment efficiency of the device. Summary of the invention

[0003] The object of the present invention is to provide a sewage treatment device for a concrete mixing plant to solve the above-mentioned deficiencies in the technology.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a sewage treatment device for a concrete mixing station, comprising a sewage sedimentation tank, a sewage inlet and a sewage outlet, wherein a filter screen is installed in the sewage sedimentation tank, and the filter screen is used to filter impurities carried by the sewage in the sewage sedimentation tank:

[0005] A sewage quick-pass component is used to clean impurities adsorbed on the surface of the filter screen, and to clean the impurities on the surface of the filter screen again by relying on water flow. The sewage quick-pass component includes a mounting plate arranged on one side of the filter screen and a cleaning column fixedly connected to one side of the mounting plate, and the cleaning column is inserted into the mesh of the filter screen, a second connecting arm is fixed on the side of the mounting plate away from the cleaning column, a first connecting arm is installed on the side of the sewage sedimentation tank close to the mounting plate, and the top of the first connecting arm is rotatably connected to one side of the second connecting arm, a connecting seat is fixed on the side of the mounting plate close to the second connecting arm, and a guide column is installed at one end of the connecting seat, a power component matched with the first connecting arm is provided on the outside of the sewage sedimentation tank, which is used to drive the first connecting arm to rotate along the sewage sedimentation tank, and to reciprocately insert and pull out the cleaning column in the mesh of the filter screen, a wave component is provided in the sewage sedimentation tank, which is used to drive the sewage to flow in the sewage sedimentation tank, and a swing component is provided in the sewage sedimentation tank, which is used to cooperate with the guide column to move along the sewage sedimentation tank, and to drive the wave component to swing back and forth: and the height of the mounting plate is less than the filter screen, and the mounting plate and the filter screen There is an adjustable distance between them to avoid the situation that the contact between them is too tight and they interfere with each other, so that the mounting plate cleans the mesh holes on the surface of the filter screen, so that the mounting plate and the cleaning column can avoid excessive contact between the impurities adsorbed on the surface of the filter screen and the impurities precipitated in the sewage sedimentation tank during cleaning, so that the height of the mounting plate in the sewage sedimentation tank is higher than the impurities precipitated in the sewage sedimentation tank. Therefore, there is a drop cleaning on the surface of the filter screen when cleaning, and the number of cleaning columns is equal to the number of mesh holes of the filter screen, and the cleaning column is a flat-top conical structure, so that there is a floating effect between the cleaning column and the mesh holes of the filter screen, avoiding the situation that the cleaning column and the mesh holes of the filter screen interfere with each other when plugging and unplugging. At the same time, the cleaning column partially extends out from the mesh holes of the filter screen to clean the impurities adsorbed on the surface of the filter screen, which can quickly remove the impurities and dirt on the filter screen, reduce the time required for cleaning the filter screen, and ensure that the filter screen always maintains a good working condition, thereby improving the effect and stability of water quality treatment. In addition, the plug-in cleaning method can reduce physical damage to the filter screen and extend its service life.

Therefore, during the movement of the mounting plate in the sewage sedimentation tank, it is used to drive the sewage around the filter screen and the mounting plate to flow, and then the flowing sewage and the sewage discharged from the sewage inlet interact with each other from different directions. The flowing water body can reduce the adsorption of impurities on the surface of the filter screen and reduce the risk of blockage, thereby improving the sewage treatment capacity.

In addition, the sewage in the sewage sedimentation tank is separated by a filter net, and the filtered sewage refers to the sewage after the sewage is filtered through the filter net, and the filtered sewage is still in the sewage sedimentation tank, which is convenient for the subsequent treatment of the sewage in the sewage sedimentation tank and improves the treatment effect of the sewage sedimentation tank on the sewage.

A connecting seat 22 is fixed on the side of the mounting plate 21 close to the second connecting arm 24, and a guide column 25 is installed at one end of the connecting seat 22. The outside of the sewage sedimentation tank 1 is provided with a guide column 25 connected to the first connecting arm 23. The power assembly 3 matched with the connecting arm 23 is used to drive the first connecting arm 23 to rotate along the sewage sedimentation tank 1, and to reciprocately insert and pull out the cleaning column 26 in the mesh of the filter screen 13. A wave assembly 5 is provided in the sewage sedimentation tank 1 to drive the sewage to flow in the sewage sedimentation tank 1. A swing assembly 4 is provided in the sewage sedimentation tank 1 to cooperate with the guide column 25 to move along the sewage sedimentation tank 1 and to drive the wave assembly 5 to swing back and forth; and the second connecting arm 24 rotates along one side of the first connecting arm 23 and the positions between them change with reference to the sewage sedimentation tank 1. The initial state of the second connecting arm 24 and the first connecting arm 23 is a vertical 7-shaped structure, and then the second connecting arm 24 and the first connecting arm 23 are adjusted to a lying 7-shaped structure.

[0041] The power assembly 3 includes a rotating column 36 installed on the side of the first connecting arm 23 away from the second connecting arm 24 and a second power rod 37 rotatably connected to one side of the sewage sedimentation tank 1, and one end of the rotating column 36 passes through the sewage sedimentation tank 1 and is installed in the second power rod 37, a support plate 31 is fixed to the side of the sewage sedimentation tank 1 adjacent to the rotating column 36, an eccentric disk 33 is rotatably connected to the side of the support plate 31 close to the sewage sedimentation tank 1, a connecting shaft column 34 is installed on the side of the eccentric disk 33 away from the support plate 31, a first power rod 35 is movably connected between the connecting shaft column 34 and the second power rod 37, a servo motor 32 is fixed to one side of the support plate 31, and the servo motor 32 is used to drive the eccentric disk 33 to rotate.

[0042] The swing assembly 4 includes a swing seat 41 fixed on one side of the sewage sedimentation tank 1 adjacent to the first connecting arm 23 and a swing plate 46 sleeved on the outside of the guide column 25. A floating hole 42 for inserting the guide column 25 is opened on one side of the swing plate 46, and there is a distance between the floating hole 42 and the guide column 25.

At this time, the sewage flows to the filter screen 13 in the sewage sedimentation tank 1, and the impurities in the sewage are blocked and filtered by the filter screen 13, which is convenient for treating the impurities in the sewage. The eccentric disk 33 is driven by the servo motor 32 to move in a circle along one side of the support plate 31, and then the connecting shaft column 34 moves in the first power rod 35 and pushes the first power rod 35 to move, so that the first power rod 35 moves to the left along one side of the sewage sedimentation tank 1.

Then the mounting plate 21 and the swing plate 46 change from a horizontal state to a vertical state. In addition, the circular motion of the eccentric disk 33 drives the first power rod 35 to reciprocate left and right along one side of the sewage sedimentation tank 1. When the first power rod 35 moves to the right along one side of the sewage sedimentation tank 1, it is used to install The plate 21 and the swing plate 46 are changed from a vertical shape to a horizontal shape, so that the mounting plate 21 can reciprocate in sequence along the sewage sedimentation tank 1, so that the mounting plate 21 and the filter screen 13 are in a plug-in connection state, which can push the impurities adsorbed on the surface of the filter screen 13 and move the impurities away from the surface of the filter screen 13, so that the impurities and dirt on the filter screen 13 can be quickly removed, and the time required for cleaning the filter screen 13 can be reduced, so as to ensure that the filter screen 13 always maintains a good working condition, which is beneficial to the normal operation of sewage treatment, and then the treated sewage in the sewage sedimentation tank 1 is discharged from the sewage outlet 12, thereby improving the effect and stability of water quality treatment.

At this time, the second gear 75 rotates to drive the synchronization rod 72, and the synchronization rod 72 rotates to drive the synchronization ring 71 to rotate synchronously, and the synchronization ring 71 rotates to drive the L rotation plate 65 to rotate, and the rotation of the L rotation plate 65 drives the rotation shaft column 66 to rotate and drive the installation frame 62 to swing outside the fixed column 52 and the sleeve 53, so that the installation frame 62 can rotate. The swing makes the wave groove 64 opened on one side contact with the guide column 61 and pushes the guide column 61 to move. Then the movement of the guide column 61 drives the sleeve 53 to rotate along the outside of the fixed column 52. Then, the movement of the sleeve 53 and the guide column 61 drives the crank arm 54 and the wave plate 55 to swing in the sewage sedimentation tank 1, so that the filtered sewage can be moved in the sewage sedimentation tank 1.
