Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of an apparatus for sludge dewatering of the present invention, as shown in fig. 1 to 11, includes a housing 110, a spin-drying mechanism 140, a flushing compression member 150, a swivel 160, an adjusting mechanism, and a driving mechanism. The spin-drying mechanism 140 includes a filter screen 141, a first spiral groove 142, and a second spiral groove 143. The filter screen 141 is rotatably disposed in the housing 110, and the first and second spiral grooves 142 and 143 are fixedly disposed on the inner circumferential wall of the filter screen 141, and the directions of rotation of the first and second spiral grooves 142 and 143 are opposite.
The flushing compression member 150 is provided in the filter screen 141 so as to be movable up and down along the axis of the filter screen 141, and a first slide block 153 is provided on the outer peripheral wall of the flushing compression member 150, and in an initial state, the first slide block 153 is slidably provided in the first spiral groove 142. The flushing compression member 150 is radially provided with a plurality of connection shafts 193, and the flushing compression member 150 is internally provided with a plurality of first compression plates 191, and the first compression plates 191 rotate around the connection shafts 193. The flushing compression member 150 is circumferentially and uniformly provided with a plurality of flushing water inlets 151.
The swivel 160 is rotatably disposed in the flushing compression member 150, and a plurality of flushing ports 161 are circumferentially and uniformly distributed on the swivel 160, and the flushing ports 161 are used for corresponding to the flushing water inlets 151 one by one, and in an initial state, the flushing ports 161 are in a closed state. The adjusting mechanism is used for rotating the swivel 160, so as to change the overlapping area of the flushing port 161 and the flushing water inlet 151. The driving mechanism is used to rotate the spin-drying mechanism 140.
In the present embodiment, as shown in fig. 7, 8 and 10, the flushing compression 150 is provided with a first sliding groove 183 and a second sliding groove 152 in the axial direction thereof. The adjustment mechanism includes a connection plate 180 and a slider 170. The connection plate 180 is provided in the first sliding groove 183 so as to be movable up and down, and friction is generated between the connection plate 180 and the first sliding groove 183. The connection plate 180 is screw-engaged with the swivel 160, and a first stopper 181 is provided on the outer circumferential wall of the connection plate 180. The slider 170 is slidably disposed in the second sliding groove 152, and there is a friction force between the slider 170 and the second sliding groove 152. The inner peripheral wall of the slider 170 is provided with a second stopper 172, and in an initial state, the second stopper 172 abuts against the first stopper 181. The slider 170 has a second slider 171 provided on the outer peripheral wall, and the second slider 171 is slidably disposed in the first spiral groove 142 in the initial state. When the filter screen 141 rotates clockwise, the second slider 171 and the first slider 153 descend along the first spiral groove 142, driving the flushing compression member 150 to move downward. When the slider 170 is raised or lowered with respect to the second sliding groove 152, the slider 170 pushes the connection plate 180 to rise or fall, and the swivel 160 is rotated, thereby changing the overlapping area of the flushing port 161 and the flushing water inlet 151.
In this embodiment, as shown in fig. 8, the lower surface of the slider 170 is provided with a spring sleeve 174. The adjusting mechanism further comprises a sensing plate 221, the spring sleeve 174 is sleeved on the sensing plate 221, and elastic pieces are arranged in the spring sleeve 174 and the sensing plate 221. When the flushing compression member 150 moves down to a certain extent, the sensing plate 221 senses the presence of sludge, and the elastic member between the sensing plate 221 and the spring sleeve 174 is compressed, and the second slider 171 is subjected to an upward force.
In this embodiment, as shown in fig. 10, a spiral protrusion is provided on the outer circumferential wall of the swivel 160, and a third spiral groove 182 is provided on the inner wall of the connection plate 180. The helical protrusion is slidably disposed within the third helical groove 182. When the connection plate 180 is raised or lowered relative to the flushing compression member 150, the connection plate 180 rotates the swivel 160.
In this embodiment, as shown in fig. 1, the driving mechanism includes a belt 120, and the belt 120 is connected to a filter screen 141. The transmission belt 120 is externally connected with a motor to drive the filter screen 141 to rotate clockwise. When the filter 141 is filled with waste water, the filter 141 rotates clockwise.
In the present embodiment, as shown in fig. 11, the first helical groove 142 and the second helical groove 143 are disposed to intersect, the pitch of the second helical groove 143 increases from top to bottom, and the pitch of the second helical groove 143 is larger than the pitch of the first helical groove 142. Since the pitch of the lowermost end of the second spiral groove 143 is the greatest, the second slider 171 pushes the connection plate 180 to move upward by the greatest distance with respect to the flushing compression member 150, and thus drives the swivel 160 to rotate by the greatest angle, and the area of the flushing port 161 overlapping the flushing water inlet 151 is the greatest, the greater the flow rate of the flushing water passing therethrough.
In the present embodiment, as shown in fig. 5, a spiral spring is provided in the first compression plate 191 and the connecting shaft 193. The flushing compression member 150 is further provided therein with a second compression plate 192, the second compression plate 192 being connected to a plurality of connection shafts 193, and a gap between the first compression plate 191 and the second compression plate 192 being closed when the flushing compression member 150 descends due to the effect of the spiral springs. When the flushing compression 150 is lifted, the gap between the first compression plate 191 and the second compression plate 192 is opened.
In this embodiment, as shown in fig. 4, only the peripheral wall of the filter screen 141 is provided with filter holes. The filtered residue falls to the bottom of the filter screen 141.
In this embodiment, as shown in fig. 1, an apparatus for sludge dewatering further includes a waste water inlet 130, the waste water inlet 130 being provided on the housing 110, the waste water inlet 130 being provided with the same hole as the flushing water inlet 151. Wastewater enters the housing 110 from the wastewater inlet 130 and the rinsed water enters the rinse water inlet 151 through the same holes as the rinse water inlet 151.
In the present embodiment, as shown in fig. 5, a plurality of filter holes are provided on the first compression plate 191 and the second compression plate 192.
The working process comprises the following steps: wastewater enters the housing 110 from the wastewater inlet 130, and the housing 110 is filled with wastewater. The transmission belt 120 is externally connected with a motor and always drives the filter screen 141 to rotate clockwise. When the filter screen 141 rotates clockwise, the second slider 171 and the first slider 153 descend along the first spiral groove 142, driving the flushing compression member 150 to move downward, and at this time, the first compression plate 191 closes the gap with the second compression plate 192 under the action of the scroll spring. The flushing compression member 150 moves down to compress sludge in the filter screen 141 to a certain extent, compressing the sludge to the bottom of the filter screen 141.
When the flushing compression member 150 moves down to a certain degree, the sensing plate 221 senses the existence of sludge, the elastic member between the sensing plate 221 and the spring sleeve 174 is compressed, and the second slider 171 is subjected to an upward force, and since the second slider 171 is in the first spiral groove 142 at this time, it cannot rise, and when the second slider 171 comes to the intersection of the first spiral groove 142 and the second spiral groove 143, the second slider 171 changes direction to come to the second spiral groove 143 under the action of the elastic member. At this time, the first sliding block 153 slides in the first spiral groove 142, the second sliding block 171 slides in the second spiral groove 143, the second sliding block 171 rises relative to the flushing and compressing member 150, the sliding block 170 rises relative to the second sliding groove 152, the second stopper 172 abuts against the first stopper 181, the sliding block 170 pushes the connecting plate 180 to move upward relative to the flushing and compressing member 150, and the swivel 160 is rotated, at this time, the overlapping area of the flushing port 161 and the flushing water inlet 151 is gradually increased, and the flushing water inlet 151 is opened. Since the pitch of the lowermost end of the second spiral groove 143 is the greatest, the slider 170 pushes the connection plate 180 to move upward by the greatest distance with respect to the flushing compression member 150, and thus drives the swivel 160 to rotate by the greatest angle, the area of the flushing port 161 overlapping with the flushing water inlet 151 is the greatest, and at this time, the greater the flow of flushing water passing through it, the greater the flow of flushing water flushes out the sludge adhering to the peripheral wall of the filter screen 141.
When the first slider 153 comes to the intersection of the first helical groove 142 and the second helical groove 143, the guiding force is not received, and at this time, the second slider 171 moves in the second helical groove 143 and receives the upward force, and because of the friction between the slider 170 and the second slider 152, the slider 170 drives the flushing compression member 150 to rise, i.e., the first slider 153 moves into the second helical groove 143, and at this time, the first turning is completed.
At this time, the first and second sliding blocks 153 and 171 move in the second spiral groove 143, and as the flushing compression member 150 moves upward, the first compression plate 191 opens a gap with the second compression plate 192 by the scroll spring so that sludge above the flushing compression member 150 passes. At this time, the position of the slider 170 with respect to the second sliding groove 152 is lowered, i.e., the first stopper 172 is separated from the second stopper 181, and the area where the flushing port 161 coincides with the flushing water inlet 151 is not changed because there is a friction between the connection plate 180 and the first sliding groove 183 so that the connection plate 180 does not drop, i.e., the swivel 160 does not rotate. Flushing of filter screen 141 is completed during the upward movement of flushing constriction 150.
When the flushing compression member 150 moves upward to the highest point, the waste water inlet 130 presses the connection plate 180 back to the original position, and the connection plate 180 moves downward to rotate the swivel 160, thereby closing the flushing port 161. When the second slider 171 reaches the intersection of the first spiral groove 142 and the second spiral groove 143 at the highest position, the second slider 171 receives a downward force from the first slider 171 into the first spiral groove 142, and the first slider 153 receives an upward force in the second spiral groove 143, and the slider 170 moves downward with respect to the second slider 152 against the friction force with the second slider 152, and returns to the initial position. The first slider 153 again goes to the first helical groove 142 to complete another commutation.
Along with the increase of the accumulation of sludge at the bottom of the filter screen 141, the time of the induction plate 221 for inducing sludge is advanced, so that the time of the compression of the elastic member in the induction plate 221 is advanced, that is, the downward stroke of the flushing compression member 150 is reduced, at this time, the amount of sludge accumulated on the inner wall of the filter screen 141 is also reduced, so that the overlapping area of the flushing port 161 and the flushing water inlet 151, that is, the flow of the flushing water passing through is reduced along with the movement distance of the slider 170 relative to the second sliding groove 152, and the change amount of the angle for driving the swivel 160 to rotate is reduced.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
