Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel construction wastewater treatment technology, specifically a tunnel construction wastewater treatment device. Background Technology
[0002] Tunnel construction refers to the design and construction methods of underground engineering projects, including tunnel construction methods, tunnel construction technology, and tunnel construction management. The most important aspect of tunnel engineering construction is the rational selection of construction methods. In the current technology, a large amount of wastewater is generated during tunnel construction. If it is discharged directly without treatment, it can easily have an adverse impact on the environment. Therefore, wastewater treatment equipment is generally used to treat construction wastewater.
[0003] Current wastewater treatment equipment for tunnel construction includes wastewater sedimentation tanks. Sludge in the wastewater can settle to the bottom of the tank, and then the settled water is pumped to the next process. However, the height of the inlet and outlet pipes of some wastewater sedimentation tanks is currently fixed. When wastewater is discharged, the large drop may cause the original settled sludge to be strongly impacted, causing the settled sludge to surge up again and reducing the sedimentation rate. The fixed outlet pipes cannot be adjusted according to the cement boundary line, which may result in incomplete water suction or excessive sludge level. Utility Model Content

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 As shown, a sewage treatment device for tunnel construction includes a sewage sedimentation tank 1. A side frame 2 is fixed to one side of the surface of the sewage sedimentation tank 1. An electric push rod 3 is fixed to the surface of the side frame 2. A drive head 5 is fixed to the output end of the electric push rod 3. A sewage supply mechanism 4 is provided on one side of the surface of the drive head 5. A water suction mechanism 6 is provided on the other side of the surface of the drive head 5. A cleaning mechanism 7 is provided on the surface of the water suction mechanism 6. A brush 8 is provided on the surface of the cleaning mechanism 7.
[0020] When water is treated by the sewage supply mechanism 4 and the water suction mechanism 6, the working positions of the sewage supply mechanism 4 and the water suction mechanism 6 can be changed under the action of the electric push rod 3 and the drive head 5, thereby achieving the effect of adjusting the sewage discharge drop and the water suction position, improving the practicality of the device. In addition, under the action of the cleaning mechanism 7, the operation of the water suction mechanism 6 can be assisted, avoiding the impact of mud and sand on the operation of the water suction mechanism 6.
[0021] The sewage supply mechanism 4 includes a sewage supply pipe 41, a first corrugated pipe 42, and a bend 43. The sewage supply pipe 41 is fixed to one side of the surface of the sewage sedimentation tank 1 and is connected to an external water pump. The first corrugated pipe 42 is connected to the other end of the sewage supply pipe 41. The bend 43 is fixed to the surface of the drive head 5 and is connected to the other end of the first corrugated pipe 42. In this embodiment, through the arrangement of the sewage supply pipe 41, the first corrugated pipe 42, and the bend 43, the sewage supply pipe 41, the first corrugated pipe 42, and the bend 43 are interconnected. When the positions of the sewage supply pipe 41 and the bend 43 change, the sewage supply pipe 41 and the bend 43 can always remain connected under the deformation of the first corrugated pipe 42.
[0022] The elbow 43 is L-shaped and its outlet faces the inner wall of the sewage sedimentation tank 1. In this embodiment, with this arrangement, when the sewage in the sewage pipe 41 reaches the elbow 43 through the first corrugated pipe 42, the water flow can be buffered by the shape of the elbow 43, and the sewage will first impact the inner cavity of the sewage sedimentation tank 1 by the direction of the elbow.
[0023] The water suction mechanism 6 includes a water suction pipe 61 fixed to one side of the surface of the sewage sedimentation tank 1. The water suction pipe 61 is connected to an external water pump. The other end of the water suction pipe 61 is connected to a second corrugated pipe 62. The other end of the second corrugated pipe 62 is connected to a filter screen 63. The filter screen 63 is fixed to the surface of the drive head 5. In this embodiment, by setting up the water suction pipe 61, the second corrugated pipe 62 and the filter screen 63, when the relative position of the water suction pipe 61 and the filter screen 63 changes, the water suction pipe 61 and the filter screen 63 can always be kept connected under the action of the second corrugated pipe 62. Under the action of the filter screen 63, the water suction process can be filtered.
[0024] The cleaning mechanism 7 includes a motor 71 fixed to the surface of the drive head 5. A connecting block 72 is fixed to the output shaft of the motor 71. A rotating rod 73 is fixed to one side of the surface of the connecting block 72. A brush 8 is fixed to the surface of the rotating rod 73. In this embodiment, through the arrangement of the motor 71, the connecting block 72 and the rotating rod 73, the connecting block 72 is rotated under the action of the motor 71. Then, under the drive of the rotating rod 73, the brush 8 cleans the surface of the filter screen 63 to avoid clogging the filter screen 63.
[0025] The motor 71 is a servo motor and has a built-in brake device. A protective cover is fixed to the surface of the motor 71 and the drive head 5. In this embodiment, this setting improves the accuracy of the motor 71 in driving the rotating rod 73 to rotate, and under the action of the brake device, the rotating rod 73 can be stably stopped at the designated position, preventing the water flow from impacting it when it is not in use. In addition, the protective cover provides protection for the operation of the motor 71 and improves the practicality of the device.
[0026] Working principle: During daily use of the sewage sedimentation tank 1, the sewage is drawn by the sewage delivery pipe 41 and the external water pump, and transported to the sewage sedimentation tank 1 through the first corrugated pipe 42 and the bend 43. During the transportation process, the electric push rod 3 causes the drive head 5 to move the bend 43, so that the bend 43 can be close to the water surface, avoiding excessive drop and strong impact on the original sludge in the sewage sedimentation tank 1. With continuous water injection, the electric push rod 3 can drive the bend 43 to move. The position of the bend 43 changes to change the drop. After the sewage settles in the sewage sedimentation tank 1, the staff can use the electric push rod 3 again to make the filter screen 63 fit the boundary between the water surface and the sludge, which improves the suction capacity of the suction mechanism 6 to absorb clean water and avoids the problem of uneven water absorption caused by changes in the sludge line. In addition, when the suction mechanism 6 is working, the brush 8 can clean the surface of the filter screen 63 under the action of the cleaning mechanism 7 to prevent sludge from clogging the filter screen 63 and causing the suction mechanism 6 to malfunction.
