[0002] River mud, also known as river silt, has long been accumulated at the bottom of the river. Its main component is clay particles. Some river silt is also mixed with some heavy metals or gravel. The water content of silt is generally higher than 100%, and some even exceed 200%. In the process of river cleaning, a large amount of silt will be generated. These silts generally have high water content and low strength. After filtering and solidification operations, various components in the silt can be reused for secondary resources.
[0003] The river mud treatment equipment of water conservancy projects generally uses a belt filter press for solid-liquid separation when treating silt. The roller drives a long separation belt loaded with silt for movement. During the movement, the water's own gravity and the roller squeeze at the end are used to continuously separate the water in the silt. Since the device cannot synchronously separate heavy metals or hard gravel mixed in the silt during the movement of the silt, the uncleanly separated solids will block the separation holes or wear the squeezing rollers during the movement of the silt, causing damage to the equipment.
[0004] When the traditional belt filter press drives the sludge for mobile extrusion-type solid-liquid separation, it lacks a structure for pre-separating solids with higher hardness, which makes it easy to wear out the equipment and cause poor separation effect. Summary of the invention

[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Example 1
[0025] like Figure 1-5 As shown, the utility model proposes a water conservancy project river channel mud processing equipment, including an outer barrel 1, the bottom of the outer barrel 1 is provided with a bucket-shaped sewage pipe, and also includes a screen inner barrel 2, the screen inner barrel 2 is installed in the outer barrel 1; a barrel cover 3, the barrel cover 3 is installed on the top of the outer barrel 1 and the screen inner barrel 2, and the barrel cover 3 is provided with an external feed pipe; a collecting mechanism 4, the collecting mechanism 4 is installed in the screen inner barrel 2; the bottom of the collecting mechanism 4 is installed with an auxiliary mechanism 5.
[0026] Furthermore, the collecting mechanism 4 includes a motor 401, which is fixedly mounted on the top of the barrel cover 3. The output shaft of the motor 401 passes through the barrel cover 3 and is fixedly connected to a clamping block 402. The bottom end of the clamping block 402 is clamped with a rotating shaft 403. The bottom end of the rotating shaft 403 is rotatably connected to the bottom of the screen inner barrel 2. A clamping groove is provided inside the rotating shaft 403, and a screen plate 404 adapted to the clamping groove is clamped therein. Collection boxes 405 are installed at the bottoms of both sides of the screen plate 404, and the collection boxes 405 are arranged back to back. Through the above arrangement, after the river mud enters the screen inner barrel 2 through the external feeding pipe, the motor 401 can be started. After the motor 401 is started, the rotating shaft 403 will be driven to rotate synchronously through the clamping block 402. At this time, the rotating shaft 403 will drive the internally clamped screen plate 404 to rotate synchronously, and the river mud in the screen inner barrel 2 is filled. The sieve plate 404 is stirred separately to prevent the river mud from settling and accumulating, and blocking the normal filtering effect of the inner barrel 2 of the screen. In the process of the sieve plate 404 stirring the river mud, the water and fine sand in the mud will enter the outer barrel 1 through the sieve holes on the inner barrel 2 of the screen, and then be discharged into the belt filter press through the bucket-shaped sewage pipe at the bottom of the inner barrel 2 of the screen for further separation. Since the screen plate 404 is also made of screen, in the above process, large particles of stone or heavy metals in the mud will be intercepted under the screening and filtration of the screen plate 404, and fall into the collection box 405 under the action of their own gravity after interception and be collected, thereby achieving the effect of collecting large particles of foreign matter, preventing large particles of foreign matter from entering the belt press, damaging the belt filter press, and affecting the filtering effect of the belt filter press. The structures of the collecting mechanism 4 itself are mostly connected by a snap-on method, which greatly facilitates the user's disassembly and maintenance.
[0027] Furthermore, the collecting mechanism 4 also includes a screen collecting bag 406, which is arranged at the bottom of the collecting box 405. The screen collecting bag 406 is made of plastic with good wear resistance. Through the setting of the screen collecting bag 406, large particles of stones and heavy metals that enter the collecting box 405 can be finally entered into the screen collecting bag 406. Since the screen collecting bag 406 has a large space, it can accommodate more foreign matter. At the same time, the screen collecting bag 406 loaded with foreign matter can also re-roll up the foreign matter that has settled to the bottom of the screen inner barrel 2 when moving, and it will be screened and filtered by the screen plate 404 again, and then collected by the collecting box 405.
[0028] Furthermore, the collecting mechanism 4 also includes an inclined shovel plate 407, which is fixedly mounted on the side of the collecting box 405 opposite to the screen plate 404. By setting the inclined shovel plate 407, when foreign matter that has settled to the bottom of the screen inner barrel 2 is rolled up again, the inclined surface of the inclined shovel plate 407 can better bring the foreign matter into the collecting box 405 for collection during the collision process.
[0029] Furthermore, the auxiliary mechanism 5 includes a magnetic rod 501, a non-magnetic sleeve 502 and a rubber sleeve 505. There are two magnetic rods 501, which are respectively arranged on one side close to the two collecting boxes 405. The magnetic rod 501 is fixedly connected to the bottom end of the rotating shaft 403. There are multiple non-magnetic sleeves 502, which are evenly installed on the bottom of the inner wall of the screen inner barrel 2. The top of the screen inner barrel 2 is slidably connected to the magnetic block 503, and the non-magnetic sleeve 502 and the magnetic block 503 are fixedly connected with a spring wire 504. The magnetic properties of the magnetic rod 501 and the magnetic block 503 are opposite. The rubber sleeve 505 is fixedly connected to the bottom of the inner wall of the screen inner barrel 2 and covers the top of the non-magnetic sleeve 502. The arrangement can achieve that when the magnetic bar 501 rotates with the rotating shaft 403, the river mud at the bottom of the screen inner barrel 2 can be stirred, so that the mud settled at the bottom of the screen inner barrel 2 can be rolled up again, and the foreign matter can be collected again. During the rotation of the magnetic bar 501, the magnetism of the magnetic bar 501 will attract the magnetic block 503 to move upward and hit the bottom of the non-magnetic sleeve 502, so that it is partially lifted, thereby achieving the effect of knocking away the mud and large particles of foreign matter settled on the non-magnetic sleeve 502, so that they are filtered and collected again by the collecting mechanism 4, and the arrangement of the spring wire 504 can assist the rising and resetting of the magnetic block 503, providing a more stable impact effect.
[0030] Among them, the top of the magnetic block 503 is set to a smooth hemispherical shape, and the non-magnetic sleeve 502 is made of good elasticity and high wear resistance. Through the above settings, the non-magnetic sleeve 502 can better cooperate with the upward impact of the magnetic block 503, and knock away foreign matter and mud settled at the bottom of the barrel 2 in the screen, so that it can be filtered and collected again.
[0031] In addition, a plurality of supporting legs 6 are fixedly connected between the bottom of the inner barrel 2 of the screen and the inner wall of the outer barrel 1. The plurality of supporting legs 6 are made of stainless steel. Through the above arrangement, a more stable supporting effect can be provided to the inner barrel 2 of the screen, and the material of stainless steel can also extend the service life of the device.
[0032] Working principle: After the river mud enters the screen inner barrel 2 through the external feed pipe, the motor 401 is started. After the motor 401 is started, the rotating shaft 403 will be driven to rotate synchronously through the clamping block 402. At this time, the rotating shaft 403 will drive the internal clamping screen plate 404 to rotate synchronously, and fully stir the river mud in the screen inner barrel 2 to prevent the river mud from settling and accumulating, blocking the normal filtering effect of the screen inner barrel 2. In the process of the screen plate 404 stirring the river mud, the water and fine sand in the mud will enter the outer barrel 1 through the screen holes on the screen inner barrel 2, and then pass through the screen inner The bucket-shaped sewage pipe at the bottom of the barrel 2 is discharged into the belt filter press for further separation. Since the screen plate 404 is also made of screen, in the above process, large particles of stone or heavy metals in the mud will be intercepted by the screening and filtration of the screen plate 404, and fall into the collection box 405 under the action of its own gravity after interception to be collected, thereby achieving the effect of collecting large particles of foreign matter, preventing large particles of foreign matter from entering the belt press, damaging the belt filter press, and affecting the filtering effect of the belt filter press. The structures of the collecting mechanism 4 itself are mostly connected by a card connection, which greatly facilitates the user's disassembly and maintenance;
[0033] Among them, the large particles of stone and heavy metals that enter the collection box 405 eventually enter the screen collection bag 406. Since the screen collection bag 406 has a larger space, it can accommodate more foreign matter. At the same time, the screen collection bag 406 loaded with foreign matter can also re-roll up the foreign matter that has settled to the bottom of the screen inner barrel 2 when it moves, and it will be screened and filtered by the screen plate 404 again, and then collected by the collection box 405. When the foreign matter that has settled to the bottom of the screen inner barrel 2 is re-rolled up, the inclined shovel plate 407 can better bring the foreign matter into the collection box 405 for collection during the collision process.
[0034] Secondly, when the magnetic bar 501 rotates with the rotating shaft 403, it can first stir the river mud at the bottom of the screen inner barrel 2, so that the mud settled at the bottom of the screen inner barrel 2 is rolled up again, and the foreign matter is collected again. During the rotation of the magnetic bar 501, the magnetism of the magnetic bar 501 will attract the magnetic block 503 to move upward and hit the bottom of the non-magnetic sleeve 502, so that it is partially lifted, thereby achieving the effect of knocking away the mud and large particles of foreign matter settled on the non-magnetic sleeve 502, so that they are filtered and collected again by the collecting mechanism 4, and the setting of the spring wire 504 can assist the rise and reset of the magnetic block 503, providing a more stable impact effect.
