As shown in fig. 1 to 4, in an embodiment of the present invention, the anti-blocking structure includes: the drum 700 comprises a first impact part 100, a fixed bracket 200 and a swinging impact member 300, wherein the first impact part 100 is arranged on the outer surface of the drum 700, the fixed bracket 200 is arranged outside the drum 700 for mounting the swinging impact member 300, and the swinging impact member 300 is rotatably mounted on the fixed bracket 200 for being lifted by the impact of the first impact part 100 and falling on the surface of the drum 700 to generate impact force for vibrating particles on the surface of the drum 700 when the drum 700 rotates.

The basic principle of the sludge treatment using the drum 700 is that: the sludge and the cleaning agent are input into the roller 700, the roller 700 is driven to rotate, so that liquid substances in the sludge leak out of water leakage holes in the surface of the roller 700 to the outside of the roller 700, solid and liquid are quickly separated, the roller 700 can be driven to rotate by a motor and other devices, or as shown in fig. 2, an outer gear ring 710 is circumferentially arranged on the outside of the roller 700 in a surrounding manner, the outer gear ring 710 is meshed with another rotatable gear (not shown in the figure), the outer gear ring 710 can be driven to rotate through the mutual meshing effect by the rotation of a driving gear, and the roller 700 synchronously rotates around the axis of the roller. On this basis, referring to fig. 2-4, after the anti-blocking structure is disposed outside the drum 700, in the process that the drum 700 rotates along direction a in the drawing, the first impact portion 100 impacts the swing impact member 300 to make it swing and lift, and along with the continuous rotation of the drum 700, the swing impact member 300 falls back to the surface of the drum 700, the particulate matter remaining and blocking in the water leakage hole on the surface of the drum 700 can be vibrated and fallen by the instant impact force generated during falling back, and along with the cyclic rotation of the drum 700, the first impact portion 100 impacts the swing impact member 300 at intervals to make it lift and fall back, so that the probability that the water leakage hole is blocked by the particulate matter for a long time is reduced.

The cleaning process does not need to be stopped, so that the long-time normal operation of the roller 700 can be ensured, and the sludge treatment efficiency is improved; because do not need artifical clearance, also need not to contact with mud, can not influence operating personnel's healthy, reduced the maintenance work volume simultaneously. Because the hole that leaks on cylinder 700 surface can not be stopped up by the particulate matter, cylinder 700 can carry out thorough roll screening and washing to mud, and the material that sees off after the processing can reach the standard of direct emission, has fully played the advantage that cylinder 700 sieves separation treatment mud of washing, has reached the best and has sieved separation effect.

In some embodiments, the swing impact member 300 may include a swing arm 310 movably connected to the fixing bracket 200 and an impact hammer 320 provided on the swing arm 310, and the swing arm 310 is lifted by an intermittent impact when the drum 700 rotates and the impact hammer 320 is dropped on the surface of the drum 700. Specifically, as the drum 700 rotates, the swing arm 310 is lifted by the impact of the first impact portion 100, and the impact hammer 320 mounted on the swing arm 310 is lifted to a certain height along with the swing arm 310 and then falls down to contact with the surface of the drum 700, so that the particles blocked in the water leakage holes on the surface of the drum 700 can be vibrated down by the instant impact force generated during the falling contact.

In some embodiments, a plurality of swing impact members 300 may be installed side by side on the fixing bracket 200. A plurality of swing impact members 300 that arrange side by side are bigger to the contact impact force that cylinder 700 surface produced, have promoted the impact strength to cylinder 700 and to the ability of falling of shaking of particulate matter, have further reduced the probability that the particulate matter remains in the hole that leaks. It will be appreciated that in other embodiments, the provision of only a single pendulum impact member 300 also ensures proper use of the present invention, and is not intended to be limiting.

In some embodiments, the plurality of swinging impact members 300 are coupled together by a linkage mechanism. Specifically, the swing impact members 300 can synchronously move by being linked together through the linkage mechanism, and can simultaneously impact the surface of the roller 700, so that the generated resonance effect improves the vibration amplitude and frequency of the wall of the roller 700, and further improves the vibration effect. In some embodiments, the linkage mechanism may be a linkage shaft 400, the linkage shaft 400 sequentially penetrates through the plurality of swinging impact members 300 to couple the plurality of swinging impact members 300 together, and referring to fig. 1, a mounting hole is formed in a corresponding position on the swinging arm 310 of each swinging impact member 300 to be used for penetrating through the linkage shaft 400, so that each swinging impact member 300 can synchronously move. It is understood that, in addition to the linkage shaft 400, in other embodiments, other coupling methods may be used, such as connecting the swing impact members 300 in series by using a coupling cable, or integrally forming the swing impact members 300 as a whole, and the present invention is not limited thereto.

In some embodiments, the impact hammer 320 is a rubber block. The impact hammer 320 made of the rubber block can reduce noise generated during impact, reduce damage and deformation to the surfaces of components colliding with each other, and protect structural members.

In some embodiments, the present invention further comprises a fork supporting body 500, wherein the fork supporting body 500 is rotatably mounted on the fixing bracket 200, and the fork supporting body 500 specifically comprises: a second striking part 510 adapted to cooperate with the first striking part 100 to force the fork carriage body 500 to rotate; and the jacking sleeve 520 is positioned between the swing impact part 300 and the roller 700 and is used for jacking the swing impact part 300 when the shifting fork support body 500 rotates under the stress. Referring to fig. 2 to 4 in particular, after the fork support body 500 is installed, when the drum 700 rotates, the first striking part 100 may first contact the second striking part 510 fixed on the fork support body 500, so that the fork support body 500 rotates; along with the rotation of the fork support body 500, the jacking sleeve 520 arranged on the fork support body 500 contacts and jacks up the swing impact part 300 to force the swing arm 310 to rotate, and the impact hammer 320 on the swing arm 310 can be lifted up to a certain height along with the swing arm 310; along with the drum 700 and the fork support body 500 continue to rotate, in the moment that the first impact part 100 breaks away from the second impact part 510 on the fork support body 500, because the fork support body 500 is no longer stressed, it directly turns back to the initial position in the reverse direction under the effect of the dead weight, at this moment, the top sleeve 520 no longer provides the jacking force to the swing impact part 300, the swing arm 310 swings in the reverse direction under the effect of the dead weight, can fall back to the surface of the drum 700, the instantaneous impact force generated to the drum wall of the drum 700 during falling back can vibrate the particulate matters remained and blocked in the water leakage holes on the surface of the drum 700. After the shifting fork support body 500 is additionally arranged, the following advantages are achieved: when the impact mechanism is implemented, the first impact part 100 cannot be in direct contact with the swing impact component 300, and the surface damage of the swing impact component 300 caused by direct collision can be reduced by jacking the swing impact component 300 by using the jacking sleeve 520, so that the service life is prolonged, and the maintenance cost is reduced; after having installed shift fork stake body 500 additional simultaneously, can effectively increase the lifting height of the jump bit 320 of swing impact part 300 to the potential energy that has increased jump bit 320 and to the impact force on cylinder 700 surface that falls under self action of gravity has further promoted the effect of shaking down to blockking up the particulate matter.

In some embodiments, as shown in fig. 3 and 4, the fork carriage body 500 and the swing impact member 300 are jointly hinge-fitted to the fixed shaft 230 of the fixed carriage 200. The shift fork support body 500 and the swing impact part 300 are jointly installed on the same fixed shaft 230 to avoid the utility model discloses a structure is too complicated, and the whole constitution is succinct with arrangement structure, has also practiced thrift manufacturing and use cost. It is understood that, in other embodiments, the fork carriage body 500 and the swing impact member 300 may be rotatably mounted on the fixing bracket 200, respectively, without affecting the normal operation of the present invention.

In some embodiments, as shown in fig. 3 and 4, the fork carriage body 500 and the swing impact member 300 are offset along the length of the fixed shaft 230. Since the fork carriage body 500 rotates relatively by the second striking part 510 thereof cooperating with the first striking part 100 on the surface of the drum 700 during the operation to lift the swing impact member 300, at the moment when the first striking part 100 is separated from the second striking part 510 of the fork support body 500, the swing impact member 300 is no longer stressed, swings reversely under its own weight and falls back to the surface of the drum 700, it is highly likely to contact the first striking part 100 of the surface of the drum 700 upon its fall back to reduce the impact strength and impact effect to the drum 700, and therefore, if the fork supporter body 500 and the swing impact member 300 can be offset in the longitudinal direction of the fixed shaft 230, the mutual interference of the shifting fork support body 500, the swing impact part 300 and the first impact part 100 in the action can be directly avoided, and the impact strength and the impact vibration effect on the roller 700 are ensured.

In some embodiments, the length direction of the fixed shaft 230 is parallel to the central axis of the drum 700. Adopt such design can make the utility model discloses an arrangement structure is more succinct, has also made things convenient for the installation of shift fork stake body 500 and swing impact member 300.

In some embodiments, as shown in fig. 4, the first striking part 100 is a bump or a rib provided on the outer surface of the drum 700. The protrusions or ribs provided on the outer surface of the drum 700 may collide with the swing impact member 300 when the drum 700 rotates.

Preferably, the first striking part 100 may be directly fixed to the outer surface of the drum 700 by using a connector such as a bolt, and when the first striking part 100 is used for a long time and needs to be replaced, the first striking part 100 may be directly removed and replaced with a new one.

It is understood that, in addition to the protrusions or ribs, in other embodiments, the first striking part 100 may also have other structures such as a striking bracket mounted on the surface of the drum 700, as long as it is disposed on the surface of the drum 700 and can cooperate with the swinging impact member 300.

In some embodiments, the second striking portion 510 is a striking pad. The second striking part 510 adopts a striking rubber pad to reduce the noise generated during striking and also reduce the surface damage to the first striking part 100 and the second striking part 510 which collide with each other, thereby prolonging the service life of the components and reducing the replacement and maintenance cost.

In some embodiments, referring to fig. 1 to 3, the swing impact device further includes a limiting portion disposed on the fixing bracket 200 for limiting a swing angle of the swing impact member 300. The reason for such design is that, when the rotation speed of the roller 700 is too fast, the impact force of the first impact portion 100 on the surface to the swing impact component 300 is large, so that the swing impact component 300 may swing to a large extent, and then the excessive impact force generated on the surface of the roller 700 during falling back causes the surface of the roller 700 to deform, and after the limiting portion is additionally arranged, the limiting portion can directly limit the swing angle of the swing impact component 300, prevent the swing impact component from swinging excessively, limit the swing angle within a reasonable swing range, and avoid large impact on the surface of the roller 700 during falling back.

In some embodiments, the position-limiting portion includes a position-limiting shaft 610, and the position-limiting shaft 610 is disposed on the fixing bracket 200 and above the swing impact member 300. Specifically, when the swing impact member 300 is impacted and swings to a relatively large extent, the swing impact member contacts with the limiting shaft 610 arranged above the swing impact member 300 and is blocked by the limiting shaft 610, so that the swing angle of the swing impact member is directly limited, the swing impact member is prevented from swinging excessively, and the surface of the roller 700 is prevented from being deformed due to relatively large impact generated on the surface of the roller during falling back.

Furthermore, a limiting sleeve 620 can be sleeved on the limiting shaft 610. The limiting sleeve 620 is in flexible contact with the surface of the swinging impact component 300 in an interaction manner, so that damage to the surfaces of the components which collide with each other can be reduced, and the service life of the components is prolonged.

In some embodiments, the fixing bracket 200 is circumferentially disposed around the drum 700. Circumference surrounding type sets up and can makes the utility model discloses holistic arrangement structure is more succinct, has made things convenient for shift fork stake body 500 and swing impact member 300's installation, has practiced thrift manufacturing cost. It should be noted that in the embodiment shown in fig. 2-4, the fixing bracket 200 surrounding the circumference of the drum 700 is in a closed structure in the circumferential direction, and in other embodiments, the fixing bracket 200 may be in a semi-closed or closed structure in the circumferential direction.

In some embodiments, the fixing bracket 200 includes a lower half support 220 and an upper half fixing ring 210, and the lower half support 220 and the upper half fixing ring 210 are fixed together by fitting at their opposite ends. The lower support half ring 220 and the upper stationary half ring 210 are assembled together to form the stationary barrier 200, which provides convenience for installation and disassembly, and only needs to replace the damaged part when the stationary barrier 200 breaks down, and does not need to be replaced completely, thereby reducing the maintenance cost.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
