Description

Technical Field

[0001] This utility model relates to the field of sludge recycling technology, specifically a sludge recycling device. Background Technology

[0002] River dredging generally refers to the management of river channels and is a water conservancy project. It uses mechanical equipment to blow and stir the silt deposited on the riverbed into a turbid water state, which is then carried away by the river water, thereby playing a role in clearing the channels. In river dredging projects, after the silt pumped out from the riverbed is initially screened and discharged, if the remaining silt needs to be recycled, it needs to undergo secondary screening.

[0003] The prior art patent document CN221544417U provides a sludge recycling and treatment device, including a treatment tank, a support rod, a drive motor, a drive shaft, a fixed screening disc, and an air chamber. The collected sludge is poured into the fixed screening disc, and then the drive motor is started. The drive motor rotates slowly, thereby driving the drive shaft to rotate slowly, which in turn drives the fixed screening disc to rotate slowly. The sludge located in the fixed screening disc is slightly disturbed by the rotation of the fixed screening disc and shakes slightly in the fixed screening disc. At this time, the sludge leaks out through the screening holes and accumulates at the bottom of the separation chamber, and is discharged through the opening of the discharge channel. The remaining sludge mixed with garbage or other foreign objects is left inside the fixed screening disc. After the sludge is discharged, the garbage and foreign objects can be manually removed, thus achieving the purpose of quickly separating and recycling sludge and garbage.

[0004] Although the device has many beneficial effects, it still has the following problems: during the use of the device, the efficiency of separating sludge and garbage by rotational inertia alone is low and the separation effect is not good enough; secondly, the sealing effect of the device is poor during use, and the splashed sludge is easy to cause pollution, which needs to be improved. In view of this, we propose a sludge recycling device. Utility Model Content

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of sludge recovery device involves feeding sludge into the screening chamber through the feed pipe, turning on the motor to drive the rotating shaft, which in turn drives the sleeve to rotate the screening chamber. Through inertia, the sludge is separated from the waste. The rotating shaft also drives the worm gear to rotate, which in turn drives the worm to rotate the cam to squeeze the screening chamber. This causes the screening chamber to move up and down repeatedly, making it easier to separate the sludge from the waste more thoroughly. The sludge falls from the screen holes into the processing tank for recovery.

[0021] This type of sludge recovery device moves the limiting block into the receiving tank by pressing it, so that the top cover is placed on the top of the feed pipe. When the limiting block is released, the spring's rebound force causes the limiting block to move and engage with the limiting groove, which facilitates locking the top cover and prevents sludge from splashing out of the feed pipe.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] This utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not be construed as limiting the scope of protection of this utility model.

It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0032] The term "connection method" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural diagram of an embodiment of a sludge recycling device, including:

[0035] Please see Figures 1-5This embodiment of a sludge recovery device includes a processing tank 1. A discharge pipe 2 is welded to the bottom of the outer circumference of the processing tank 1. A screening assembly 3 is rotatably connected inside the processing tank 1. The screening assembly 3 includes a motor 301 located at the bottom of the processing tank 1. A rotating shaft 302 is fixedly mounted at the output end of the motor 301. A sleeve 303 is slidably connected to the outer circumference of the rotating shaft 302. A screening chamber 304 is welded to the outer circumference of the sleeve 303. Multiple screen holes 305 are opened on the outer circumference of the screening chamber 304. A worm gear 306 is fixedly mounted on the outer circumference of the rotating shaft 302. The worm gear 306 meshes with a worm 307. A cam 308 is fixedly mounted on the outer circumference of the worm 307. A cam 308 is fixedly mounted on the top of the screening chamber 304. The feed pipe 4 has a sealing component 5 attached to its top. The discharge pipe 2 has a discharge valve 6 fixed to its outer circumference. The motor 301 is electrically connected to an external power source. By feeding sludge into the screening chamber 304 through the feed pipe 4, the motor 301 is turned on to drive the rotating shaft 302 to rotate, which in turn drives the sleeve 303 to rotate the screening chamber 304. The sludge and garbage are separated by inertia. The rotation of the rotating shaft 302 also drives the worm gear 306 to rotate, which in turn drives the worm 307 to rotate and drive the cam 308 to rotate and squeeze the screening chamber 304. This causes the screening chamber 304 to move up and down repeatedly, which facilitates more thorough separation of sludge and garbage. The sludge falls from the screen holes 305 into the processing tank 1 for recycling.

[0036] It is worth noting that, in order to prevent sludge from splashing, the sealing component 5 specifically includes a top cover 501, and multiple receiving grooves 502 are provided on the outer circumference of the feed pipe 4. Multiple springs 503 are fixed on the side wall of the receiving grooves 502, and a limiting block 504 is fixed on the other end of the springs 503. A limiting groove 505 is provided on the inner circumference of the top cover 501. By pressing the limiting block 504 to move into the receiving groove 502, the top cover 501 is placed on the top of the feed pipe 4. When the limiting block 504 is released, the spring force of the spring 503 drives the limiting block 504 to move and engage with the limiting groove 505, which facilitates locking the top cover 501 and prevents sludge from splashing out of the feed pipe 4.

[0037] Next, in order to facilitate the rotation of the cam 308 to drive the screening chamber 304 to move up and down, specifically, the worm 307 is rotatably connected to the inner circumference of the processing barrel 1, and the position of the bottom of the screening chamber 304 matches the position of the cam 308. The worm wheel 306 is rotatably connected to the inner circumference of the processing barrel 1 to prevent the worm wheel 306 from falling off.

[0038] Meanwhile, in order to improve the sludge screening efficiency, specifically, the outer circumferential wall of the screening chamber 304 is inclined, and the diameter of the top of the screening chamber 304 is larger than the diameter of the bottom. The inclined outer circumferential wall of the screening chamber 304 makes it easier to increase the area and thus increase the mesh number of the screen holes 305, thereby improving the screening efficiency. The fact that the top diameter is larger than the bottom prevents sludge from splashing upwards.

[0039] Further, to make the top cover 501 more stable, specifically, the cross-section of the limiting block 504 is in a "C" shape, and the size of one end of the limiting block 504 matches the size of the limiting groove 505. The "C"-shaped limiting block 504 that matches the size of the limiting groove 505 facilitates pressing and improves the closing stability of the top cover 501 at the same time.

[0040] It should be noted that to make the treatment barrel 1 more stable, specifically, a plurality of support columns 7 are welded to the bottom of the treatment barrel 1, and a backing plate 8 is fixedly provided at the bottom of each of the plurality of support columns 7. The stability of the treatment barrel 1 is improved by the support columns 7.

[0041] Finally, to prevent the support columns 7 from sliding, specifically, the blanking valve 6 is a pneumatic O-shaped ball valve, and the material of the backing plate 8 is nitrile rubber. The pneumatic O-shaped ball valve facilitates controlling the fall of the treated sludge, and the excellent oil resistance, high wear resistance, heat resistance, and strong adhesion facilitate increasing the friction force.

[0042] In addition, the circuits, electronic components, and modules involved in the present utility model are all prior arts, and those skilled in the art can fully implement them without further elaboration. The content protected by the present utility model also does not involve improvements to the internal structure and method.

[0043] The device or equipment models involved in this article are as follows:

[0044] Motor 301: Y90S-2.

[0045] Combined Figures 1-5 , a sludge recovery device of this embodiment is used as follows:

[0046] 1: When this device is needed for sludge recovery, add the sludge from the feed pipe 4 to the screening bin 304, start the motor 301 to make the rotating shaft 302 drive the sleeve 303 to rotate, so that the screening bin 304 rotates to separate the sludge and the garbage. While the rotating shaft 302 rotates, the worm wheel 306 rotates to drive the worm 307 to rotate, so that the cam 308 rotates to squeeze the screening bin 304 to move up and down reciprocally, and the sludge falls into the interior of the treatment barrel 1 through the screen holes 305.

[0047] 2: Press the limiting block 504 to make the limiting block 504 move into the accommodating groove 502, cover the top cover 501 on the top of the feed pipe 4, and release the limiting block 504. The resilience of the spring 503 drives the limiting block 504 to reset and enter the interior of the limiting groove 505.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
