Description

Technical Field

[0001] This utility model relates to the field of sludge suction machine technology, specifically to a sludge suction nozzle and a sludge suction machine using the sludge suction nozzle. Background Technology

[0002] Sludge suction machines are mainly used in sewage treatment plants and waterworks horizontal flow sedimentation tanks. They can suck the sludge settled at the bottom of the tank into the suction nozzle through a siphon effect, and then discharge it to the outside of the sedimentation tank through the suction pipe.

[0003] However, the suction nozzles of existing sludge suction machines are usually fixed, which is inconvenient to disassemble. This makes it difficult to clean the nozzles manually. If the nozzles are not cleaned for a long time, the residual mud will gradually dry, eventually causing the nozzle holes to become smaller and smaller, or even become blocked.

[0004] To address this issue, we propose a suction nozzle and a suction machine using this nozzle. Utility Model Content

Detailed Implementation

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings. Example 1

[0029] like Figure 1-6As shown, this utility model provides a technical solution: a suction nozzle, including a disassembly and assembly mechanism 31. The disassembly and assembly mechanism 31 includes an absorption pipe 311 fixedly installed on the lower part of the machine body 1 by a fixing block. A telescopic pipe 312 is connected to the lower part of the absorption pipe 311. A first hydraulic cylinder 315 is fixedly installed at the bottom of the machine body 1. An installation plate 316 is fixedly connected to the output end of the first hydraulic cylinder 315. An installation pipe 313 is fixedly installed inside the installation plate 316. A suction nozzle 314 is provided at the bottom of the installation pipe 313. An installation ring 317 is fixedly connected to the inner wall of the installation pipe 313. A sealing ring 318 is fixedly connected to the bottom of the installation ring 317. A sliding groove 319 is opened on the outer wall of the installation pipe 313. A slide rod 3110 is fixedly connected to the inner wall of the machine body 9. A slider 3111 is slidably connected to the outer wall of the slide rod 3110. A first spring 3112 is fixedly connected to the inner wall of the slide groove 319. A connecting rod 3113 is fixedly connected to the outer side of the slider 3111. A snap-fit ​​rod 3114 is movably connected to the bottom end of the connecting rod 3113. A pull rod is fixedly connected to the outer end of the snap-fit ​​rod 3114. A second spring 3115 is fixedly connected to the outer side of the connecting rod 3113. A positioning groove 3116 is opened on the inner wall of the mounting tube 313. A positioning block 3117 is fixedly connected to the outer wall of the top end of the suction nozzle 314. A snap-fit ​​groove 3118 is opened on the outer wall of the top end of the suction nozzle 314. A discharge pipe 3119 is fixedly installed on the upper part of the machine body 1 by a fixing block.

[0030] In this embodiment, the bottom of the telescopic pipe 312 is connected to the mounting pipe 313, the absorption pipe 311 is connected to the input end of the sludge pump 2, and the discharge pipe 3119 is connected to the output end of the sludge pump 2.

[0031] Furthermore, one end of the first spring 3112 is fixedly connected to the slider 3111, a snap-fit ​​hole is provided on the outer wall of the mounting tube 313, and the snap-fit ​​rod 3114 is snapped into the snap-fit ​​groove 3118 through the snap-fit ​​hole. The end of the second spring 3115 away from the connecting rod 3113 is fixedly connected to the pull rod.

[0032] Furthermore, the positioning block 3117 is adapted to the positioning groove 3116.

[0033] When slurry needs to be absorbed, the first hydraulic cylinder 315 drives the mounting plate 316 downward. Under the action of the telescopic tube 312, the suction nozzle 314 located at the lower part of the mounting plate 316 can move downward. Then, the slurry can be absorbed by the slurry pump 2. When the suction nozzle 314 needs to be disassembled, simply hold the pull rod and pull the locking rod 3114 outward to separate the locking rod 3114 from the locking groove 3118. Then, under the action of the elastic force of the first spring 3112, the slider 3111 can move through the sliding rod 3. 110 moves within the slide groove 319, thereby allowing the connecting rod 3113, which is fixedly connected to the outside of the slider 3111, to move upward synchronously. This allows the locking rod 3114 to stop at a position away from the locking groove 3118, freeing up the operator's hands. The nozzle 314 can then be manually removed. With the help of the positioning groove 3116 and the positioning block 3117, it is easy for the operator to insert the top of the nozzle 314 into the installation tube 313, which also has a positioning effect, making it easier for the operator to subsequently lock the locking rod 3114 into the locking groove 3118. Example 2

[0034] Based on Embodiment 1, a preferred embodiment of the sludge suction machine using this suction nozzle provided by this utility model is, for example... Figures 1 to 6 As shown: A sludge suction machine using this suction nozzle includes a body 1, a sludge pump 2 fixedly installed on the left side of the body 1 via a base, a connecting column 4 fixedly installed at the bottom of the body 1, a support leg 5 sleeved on the outside of the connecting column 4, a third hydraulic cylinder 6 fixedly installed inside the support leg 5, and a connecting assembly 3 located on one side of the body 1. The connecting assembly 3 includes a disassembly and assembly mechanism 31 located at the lower part of the body 1. A filter mechanism 32 is provided inside the body 1. Heat dissipation holes are provided on the side wall of the support leg 5. The output end of the third hydraulic cylinder 6 is fixedly connected to the connecting column 4. The filter mechanism 32 includes a partition 325 fixedly connected to the inner wall of the body 1, a filter plate 321 fixedly connected to the inner wall of the body 1, and a guide plate 322 fixedly connected to the inner wall of the body 1. A second hydraulic cylinder 323 is fixedly installed on the back of the body 1 via a base. A push plate 324 is fixedly connected to the output end of the second hydraulic cylinder 323. A discharge port 326 is provided at the front of the body 1. A box door is provided on the outside of the discharge port 326. A water outlet pipe is connected to the front of the body 1.

[0035] In this embodiment, the push plate 324 is arranged to contact the partition plate 325 on one side and to contact the inner wall of the body 1 on the other side.

[0036] When the sludge is conveyed to the upper part of the filter plate 321 through the discharge pipe 3119, the sludge can be screened and separated by the filter plate 321. The sewage will fall into the machine body 1, and under the action of the partition plate 325, the machine body 1 can be separated. The sewage will fall to the left side, and the sludge will slide through the filter plate 321 to the right side of the partition plate 325. Then, the second hydraulic cylinder 323 drives the push plate 324 to push forward and open the box door, thereby compressing and squeezing out the sludge, which makes it easier for the sludge to be processed manually in the future.
