Description

Technical Field

[0001] The utility model relates to the technical field of sludge suction machines, in particular to a truss type sludge suction machine. Background Art

[0002] The car-type scraper is a kind of mud discharge equipment, which is installed on the rectangular horizontal flow sedimentation tank. The scraper is mainly composed of a working bridge, a transmission device, a scraper plate, a sludge lifting pump, etc. The machine is equipped with a fixed platform across the sedimentation tank. The sediment in the sewage settles at the bottom of the tank. The scraper scrapes the settled sludge into the central mud collection pit and uses the sludge pump to discharge the sludge.

[0003] However, in the prior art, traditional sludge suction machines usually utilize the rotation of a pump to generate suction, which is then extended to the bottom of the pool through a pipe to absorb the sludge at the bottom of the pool. However, after the sedimentation tank has not been cleaned for a long time, the sludge at the bottom of the pool will accumulate and become stubborn mud blocks. Therefore, traditional sludge suction machines need to increase the suction of the pump if they want to absorb the stubborn sludge, otherwise they will not be able to absorb the stubborn mud blocks. In addition, after long-term use, the traditional sludge suction machine will wear out due to the friction between the sludge suction head and the bottom of the pool, thereby affecting the working efficiency of the sludge suction machine.

[0036] A quick-connect mechanism 7, the top of which is slidably connected to the inner wall of the bottom of the sewage discharge mechanism 6;

[0037] The sewage discharge mechanism 6 includes a fixed pipe 64, the bottom of which is rotatably connected to a partition shell 62, the inner wall of which is slidably connected to a scraper shell 63, a spiral rod 61 is arranged inside the fixed pipe 64, and the sludge at the center of the scraper shell 63 is discharged to the top of the fixed pipe 64 through the rotation of the spiral rod 61, the inner wall of the bottom of the spiral rod 61 is slidably connected to the top of the quick-connect mechanism 7, the top of the fixed pipe 64 is fixedly connected to the bottom of the gantry vehicle body 3, the bottom of the partition shell 62 is slidably connected to the inner wall of the bottom of the sedimentation tank 1, the outer wall of the fixed pipe 64 is fixedly connected to the outer wall of the sewage discharge pipe 5, the top of the spiral rod 61 is fixedly connected to the output end of the stepper motor 4, and the outer wall of the scraper shell 63 is fixedly connected to a scraper plate 65.

[0038] The outer wall of the scraper blade 65 is fixedly connected with a supporting rib 66, and is linearly arrayed along the outer wall of the scraper blade 65. The outer wall of the scraper blade 65 is slidably connected to the inner wall of the bottom of the sedimentation tank 1. The inner wall of the scraper shell 63 is fixedly connected with a guide plate 67, and is annularly arrayed along the central axis of the scraper shell 63. The quick-connect mechanism 7 includes a plug column 72, the bottom of the plug column 72 is fixedly connected to a limiting ring 73, the outer wall of the plug column 72 is slidably connected to the inner wall of the fixed block 76, the outer wall of the fixed block 76 is fixedly connected to a limiting rod 75, the limiting rod 75 slides into the scraper shell 63 through the sliding groove in the wall of the scraper shell 63, so that the scraper shell 63 and the fixed block 76 rotate synchronously, and are annularly arrayed along the central axis of the fixed block 76.

[0039] The outer wall of the top of the plug post 72 is fixedly connected with a slider 74, and is arranged in a ring shape along the central axis of the plug post 72. The slider 74 is used to slide into the positioning groove in the screw rod 61, and the position of the positioning groove is consistent with the rotation direction of the screw rod 61. Therefore, when the screw rod 61 rotates, the slider 74 will not slide out of the positioning groove, and the outer wall of the slider 74 is slidably connected to the inner wall of the bottom of the screw rod 61. The top of the fixed block 76 is fixedly connected to the limiting column 71, and is arranged in a ring shape along the central axis of the fixed block 76.

[0040] Working principle:

[0041] When in use, first move the gantry body 3 along the track 2 on the top of the sedimentation tank 1 to any side of the sedimentation tank 1, then start the stepper motor 4, and drive the sewage discharge mechanism 6 to rotate through the stepper motor 4, start the gantry body 3 again, and drive the sewage discharge mechanism 6 to slide back and forth at the bottom of the sedimentation tank 1 through the gantry body 3, and then discharge the sludge at the bottom of the sedimentation tank 1 into the sewage pipe 5, and then discharge it to the outside through the sewage pipe 5. When the mud suction head in the sewage discharge mechanism 6 is used for a long time and is damaged or the mud suction effect is reduced, the mud suction head can be quickly replaced through the quick connection mechanism 7 at the bottom of the sewage discharge mechanism 6, thereby restoring the working efficiency of the mud suction machine.

[0042] When the gantry vehicle body 3 moves to one side of the sedimentation tank 1, the stepper motor 4 is then started, and the screw rod 61 is driven to rotate by the stepper motor 4. With the continuous rotation of the screw rod 61, the sludge at the bottom of the fixed pipe 64 is discharged to the top of the fixed pipe 64. Then, with the continuous rotation of the screw rod 61, the sludge at the bottom of the fixed pipe 64 is continuously transported to the top, and then the sludge at the top of the fixed pipe 64 is squeezed into the sewage pipe 5 and then discharged to the outside.

[0043] The scraper shell 63 is connected to the spiral rod 61 through the quick connection mechanism 7, so when the spiral rod 61 rotates, the scraper shell 63 also rotates synchronously. A scraper plate 65 is fixed to the scraper shell 63. Therefore, when the scraper shell 63 rotates, the scraper plate 65 hangs the sludge at the bottom of the sedimentation tank 1 into the scraper shell 63. Because a guide plate 67 is provided inside the scraper shell 63, the sludge is discharged to the center of the scraper shell 63 under the guidance of the guide plate 67. The sludge discharged to the center of the scraper shell 63 is discharged to the top of the fixed pipe 64 through the rotation of the spiral rod 61. A support rib 66 is fixed to the scraper plate 65. When stubborn sludge is scraped, the support ribs 66 first break and disperse the sludge, and then scrape it into the scraper shell 63 under the scraping of the scraper blade 65. At the same time, the support ribs 66 also increase the structural strength of the scraper blade 65. Because a partition shell 62 is provided on the outside of the scraper shell 63, when the scraper shell 63 is working, the gantry body 3 is started, and the partition shell 62 moves synchronously with the gantry body 3 through the fixed pipe 64, so that the partition shell 62 breaks the sludge before the scraper shell 63 during its movement at the bottom of the sedimentation tank 1, and then performs preliminary breaking of the sludge, thereby increasing the working efficiency of the partition shell 62 in breaking stubborn sludge.

[0044] When the sewage mechanism 6 has been used for a long time, it will be worn out due to long-term friction with the bottom of the pool, and the mud discharge effect of the sewage mechanism 6 will deteriorate. The mud scraper shell 63 can be quickly replaced through the quick-connect mechanism 7. First, rotate the limit ring 73 to make the limit ring 73 drive the plug post 72 to rotate synchronously, so that the slider 74 can slide out of the positioning groove in the spiral rod 61. After the slider 74 slides into the groove in the spiral rod 61, pull the limit ring 73 downward to make the limit ring 73 drive the plug post 72 to slide out of the spiral rod 61, so as to release the restriction of the limit ring 73 on the fixed block 76.

[0045] Then the fixing block 76 can be slid out from the spiral rod 61 and the scraper shell 63, and then the scraper shell 63 can be replaced, the old scraper shell 63 can be taken out of the fixing tube 64, and then the new scraper shell 63 can be slid back into the fixing tube 64, and then the limiting rod 75 can be slid back into the scraper shell 63, and then the limiting column 71 on the fixing block 76 can be slid back into the spiral rod 61. After the fixing block 76 is initially fixed to the bottom of the spiral rod 61, the position of the fixing block 76 is maintained, and the plug column 72 is slid back into the spiral rod 61 along the slide groove on the spiral rod 61. After the slider 74 slides to the top of the slide groove, the plug column 72 is rotated, thereby driving the slider 74 to slide back into the positioning groove, thereby limiting the position of the fixing block 76.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
