Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tank sludge treatment, in particular to a sewage sedimentation tank sludge treatment device. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is a water purifier that uses the natural sedimentation or coagulation sedimentation of water to remove suspended matter from water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank.

[0003] In the existing sewage sedimentation tank used for domestic sewage, solid particles, sedimentation materials and precipitated organic matter in the domestic sewage will settle to the bottom of the sewage sedimentation tank to form sludge during long-term use. When the sludge at the bottom of the sewage sedimentation tank is sufficient, the sludge needs to be discharged. The traditional method of treating the sludge at the bottom of the sewage sedimentation tank is generally to use a suction device to suck the sludge at the bottom of the sewage sedimentation tank. However, the suction head of the general suction device is limited in size, resulting in a low suction efficiency for the sludge at the bottom of the sewage sedimentation tank. Therefore, we propose a sewage sedimentation tank sludge treatment device to solve the above problem. Utility Model Content

[0009] Preferably, the two barrel openings on the sludge collecting barrel are symmetrically arranged, and the two barrel openings on the sludge collecting barrel are connected with the sedimentation chamber, so that the sludge in the sedimentation chamber can flow into the sludge collecting barrel through the two barrel openings.

[0010] Preferably, the two discharge ports on the sludge collecting barrel are arranged in a staggered manner, and the corresponding discharge ports on the sludge collecting barrel are connected to the discharge pipe, so that the sludge transported to the corresponding discharge ports on the sludge collecting barrel can be transported to the discharge pipe.

[0021] Furthermore, the bottom inner wall of the sedimentation chamber 2 is inclined downward, and a bottom opening is provided between the two sloped side plates 4 and one inner wall of the sedimentation chamber 2 , so as to facilitate the sedimentation of sludge into the groove between the slope of the bottom inner wall of the sedimentation chamber 2 and the arc plate 3 .

[0022] Furthermore, the rotation drive mechanism includes a first motor 7 and a first drive rod 8. The first motor 7 is fixedly installed on the outer wall of one side of the sewage sedimentation tank body 1, and one end of the first drive rod 8 is fixedly installed on the output shaft of the first motor 7. The other end of the first drive rod 8 extends into the rotating trough 5 and is fixedly installed on the outer wall of one side of the sludge collecting barrel 6; by starting the first motor 7, the rotation adjustment of the sludge collecting barrel 6 can be realized, which is convenient for realizing the sludge treatment of the sedimentation area on the right or left side of the sedimentation chamber 2.

[0023] Specifically, the two barrel openings 9 on the sludge collecting barrel 6 are symmetrically arranged, and the two barrel openings 9 on the sludge collecting barrel 6 are connected with the sedimentation chamber 2 , so that the sludge in the sedimentation chamber 2 can flow into the sludge collecting barrel 6 through the two barrel openings 9 .

[0024] Specifically, the two discharge ports 10 on the sludge collecting barrel 6 are staggeredly arranged, and the corresponding discharge ports 10 on the sludge collecting barrel 6 are connected to the discharge pipe 15 , so that the sludge transported to the corresponding discharge ports 10 on the sludge collecting barrel 6 can be transported to the discharge pipe 15 .

[0025] Specifically, the sludge discharge driving mechanism includes a second motor 11, a second driving rod 12 and a spiral conveying blade 13.

At the same time, by starting the second motor 11, the second driving rod 12 drives the two spiral conveying blades 13 in the sludge collecting barrel 6. Rotation, since the rotation directions of the two spiral conveying blades 13 are opposite, the sewage and sludge flowing into the sludge collecting barrel 6 are synchronously conveyed from both ends to the corresponding discharge ports 10 on the sludge collecting barrel 6, and flow into the discharge pipe 15 through the discharge port 10, and then the sludge is discharged to the outside of the sewage sedimentation tank body 1 through the discharge pipe 15, so that the sludge in the right sedimentation area of ​​the sewage sedimentation tank body 1 is processed; similarly; when it is necessary to process the sludge in the left sedimentation area in the sedimentation chamber 2, by starting the first motor 7, the first driving rod 8 drives the sludge collecting barrel 6 to rotate in the opposite direction, so that the two barrel openings 9 on the sludge collecting barrel 6 are connected with the left sedimentation area of ​​the sedimentation chamber 2, so that the sewage in the left sedimentation area of ​​the sedimentation chamber 2 enters the sludge collecting barrel 6 along with the sludge through the two barrel openings 9 on the sludge collecting barrel 6, and the operation is repeated, so that the sludge in the left sedimentation area of ​​the sedimentation chamber 2 can be processed.
