Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 6, the embodiment of the high-efficiency dust removing device of the dry cleaning machine of the present invention includes a housing 125, a cyclone separating mechanism, a knocking mechanism 140, a driving mechanism and a transmission mechanism.

A containing cavity is arranged in the shell 125, an air inlet pipeline 120 is arranged on the side wall of the upper end of the shell 125, and an ash bucket 131 is arranged at the lower end. The cyclonic separating mechanism comprises a spiral scroll 124 and an exhaust duct 111. The spiral scroll 124 is disposed in the accommodating cavity and telescopically disposed in the up-down direction, the spiral scroll 124 spirally extends from the upper end to the lower end, the lower end is fixedly connected to the housing 125, an air flow channel is formed in the middle of the spiral scroll 124, the aperture of the air flow channel gradually decreases from the top to the bottom, the lower end of the air flow channel is communicated with the ash bucket 131, and the upper open end of the spiral scroll 124 is communicated with the air inlet pipe 120 through a connecting hose 124 c. The exhaust pipe 111 is vertically arranged, fixedly inserted in the middle of the airflow channel, the upper end of the exhaust pipe is communicated with the outside, and the lower end of the exhaust pipe is positioned below the air inlet pipeline 120. The waste gas with dust enters the airflow channel from the air inlet pipe 120 through the connection hose 124c, the waste gas moves downwards in a spiral manner under the guiding action of the pipe wall of the spiral scroll 124, the dust in the waste gas is thrown outwards under the action of the cyclone centrifugal force to be separated from the gas, and the separated dust falls on the lower pipe wall of the spiral scroll 124 and finally slides downwards along the lower pipe wall of the spiral scroll 124 to fall into the dust hopper 131. The clean gas flows downward to the lower end of the spiral scroll 124 to form an inner spiral flow, and then starts to flow upward and is discharged from the gas discharge pipe 111.

The wall of spiral scroll 124 is provided with detection net 124a, and knocking mechanism 140 is disposed outside spiral scroll 124, and includes a support rod 141 and a knocking wheel 142, and support rod 141 is rotatably mounted on the upper end of spiral scroll 124 around its axis. The knocking wheel 142 is fixedly sleeved on the support rod 141 and is used for knocking the spiral scroll 124 when the support rod 141 rotates. The drive mechanism includes a sensing assembly and a gear 128 with an axis in a vertical direction. The sensing assembly is configured such that the driving gear 128 rotates about its axis as the gas passes through the gas inlet duct 120, and the driving gear 128 rises when the flow rate of the gas exceeds a preset range. The transmission mechanism is configured to convert the rotation of the gear 128 into the rotation of the support rod 141 about its axis when the upper end of the spiral scroll 124 is raised a predetermined distance relative to the gear 128.

When exhaust gas passes through the intake conduit 120, it acts on the sensing assembly, causing the sensing assembly to drive the gear 128 to rotate. When the speed of the airflow exceeds a certain range, the gear 128 is lifted by the sensing component.

When the airflow increases, the pressure of the airflow channel in the spiral scroll 124 also increases, so that the spiral scroll 124 expands and stretches in the vertical direction, the upper end of the spiral scroll 124 moves upward, and the support rod 141 is driven to move upward synchronously, but at this time, the rotation of the gear 128 cannot be converted into the rotation of the support rod 141 around the axis thereof through the transmission mechanism.

As the usage time increases, dust accumulates on the inner wall of the spiral scroll 124, and the roughness of the inner wall of the spiral scroll 124 increases, so that the dust removal efficiency decreases, and the detection net 124a gradually blocks. At this time, the spiral scroll 124 expands no matter whether the flow rate of the gas is increased or not, so that the upper end of the spiral scroll 124 drives the support rod 141 to move upwards synchronously, and when the upper end of the spiral scroll 124 rises for a preset distance relative to the gear 128, the second transmission mechanism converts the rotation of the gear 128 into the rotation of the support rod 141 around the axis thereof. When the supporting rod 141 rotates, the knocking wheel 142 on the supporting rod is driven to knock the spiral scroll 124, so that the spiral scroll 124 vibrates to remove dust on the inner wall of the spiral scroll 124 and avoid the reduction of dust removal efficiency.

In one embodiment, as shown in fig. 2 and 3, a first fixed cylinder 126 with an upward opening is mounted on the upper portion of the air inlet duct 120, and an opening communicated with the mounting cavity is provided on the second fixed cylinder 127. The induction assembly includes a spindle 151, an impeller 153, and a rotating member. The spindle 151 is vertically disposed and penetrates through the first fixed cylinder 126, the air inlet duct 120 and the second fixed cylinder 127, a lower end of the spindle 151 is fixed to a cylinder wall of the second fixed cylinder 127, and the impeller 153 includes a sleeve 1531 and a plurality of blades 1532. The sleeve 1531 is slidably sleeved on the core shaft 151 in the up-down direction, and a lower end of the sleeve 1531 is fixedly connected to a middle portion of an upper end surface of the gear 128. The plurality of blades 1532 are radially arranged in the first fixing cylinder 126, an inner end of each blade 1532 is fixedly connected to the sleeve 1531, and the blades 1532 are spirally arranged to guide the external air downward when the impeller 153 rotates, so that the impeller 153 has a tendency to ascend. The rotating member is disposed in the air inlet duct 120 and includes a rotating cylinder and a plurality of flaps 152, and the sleeve 1531 is slidably engaged with the rotating cylinder in the up-down direction and rotates synchronously. The plurality of flaps 152 are mounted to the drum, and specifically, the plurality of flaps 152 are inclined in one direction for driving the drum to rotate around one direction all the time under the action of the airflow.

When the exhaust gas passes through the gas inlet duct 120, the gas flow acts on the flap 152, so that the flap 152 drives the impeller 153 to rotate in one direction through the rotating cylinder, the impeller 153 drives the gear 128 below to rotate around the axis of the impeller 153, the impeller 153 guides the external gas flow downwards during rotation, the impeller 153 has a tendency of moving upwards under the pushing action of the gas at the lower part, and the higher the flow rate of the gas is, the faster the rotation speed of the impeller 153 is. When the speed of the air flow driving the impeller 153 exceeds a certain range, the impeller 153 drives the sleeve to move upwards under the pushing action of the air at the lower part, and the sleeve drives the gear 128 to ascend.

In one embodiment, as shown in fig. 2, the high-efficiency dust removing device of the dry cleaning machine further comprises a support plate 121 and a connecting cylinder 122. Support plate 121 is fixedly mounted on the upper end of spiral scroll 124, and exhaust pipe 111 is fixedly inserted into support plate 121. The connecting cylinder 122 is located below the supporting plate 121, the upper end of the connecting cylinder is fixedly connected with the supporting plate 121, and a side port for allowing a connecting hose to pass through is arranged on the connecting cylinder, so that the influence of the up-and-down movement of the upper end of the spiral scroll 124 on the entering of waste gas is prevented. The inner peripheral wall of the connecting cylinder 122 is provided with a limiting plate, the limiting plate is provided with a through hole, and the support rod 141 is rotatably arranged in the through hole of the limiting plate through a bearing.

In one embodiment, the transmission mechanism includes a swivel 123, a bevel gear 143, and a bevel gear ring. The rotary ring 123 rotatably mounts the connecting cylinder 122, and in an initial state, the position of the rotary ring 123 in the horizontal direction is lower than the position of the gear 128 in the horizontal direction, and the outer peripheral wall of the rotary ring 123 is provided with a toothed ring for meshing with the gear 128. A bevel gear 143 is fixedly fitted to an upper end of the support rod 141, and a bevel ring gear is disposed on an inner circumferential wall of the swivel 123 and engaged with the bevel gear 143, so that when the bevel ring gear is engaged with the gear 128, the rotation of the gear 128 drives the support rod 141 to rotate through the bevel ring gear and the bevel gear 143. Therefore, when the toothed ring engages with the gear 128, it indicates that the spiral scroll 124 expands and stretches due to the clogging of the screen, and it is necessary to clean up the dust accumulated on the spiral scroll.

In one embodiment, support rod 141 is parallel to the generatrix of spiral scroll 124. The support rod 141 has a plurality of knocking wheels 142, the distance between every two adjacent knocking wheels 142 is the same as the pitch of the spiral scroll 124, and each knocking wheel 142 corresponds to the outer convex part of the spiral scroll 124, so that the knocking wheels 142 have the same size. The knocking wheel 142 is a cam, the short end of each cam is fixedly sleeved on the support rod 141, and the long end is used for knocking the spiral worm.

In one embodiment, as shown in fig. 2, the plurality of knocking mechanisms 140 are uniformly distributed around the outer circumference of the spiral scroll 124, so as to facilitate multi-directional impact on the spiral scroll 124 and further improve the dust removal effect.

In one embodiment, as shown in FIG. 3, flap 152 is flush with inlet duct 120. The sleeve 1531 is in sealing sliding fit with the first fixed cylinder 126 and the second fixed cylinder 127, and the lower end of the sleeve 1531 is connected to the lower wall of the second fixed cylinder 127 through the spring 154, and since the spring 154 is compressed by the gravity of the impeller 153 and the gear 128 in the initial state, the restoring force of the spring 154 also has a force urging the impeller 153 to rise when the impeller 153 rotates.

In one embodiment, as shown in fig. 4, a detecting net 124a is disposed on the upper wall of the spiral scroll 124 of each pitch segment for blocking solid particles in the gas, on one hand for blocking the discharge of dust, and on the other hand for detecting whether the expansion of the spiral scroll 124 is caused by too much dust.

In one embodiment, the connection hose 124c is a bellows to facilitate deformation of the connection hose 124 c.

In one embodiment, the lower end of the spiral scroll 124 is fixedly connected to the bottom wall of the housing 125 via a flange 124b, and the efficient dust removing device of the dry cleaner further includes an extension pipe, which communicates the airflow channel with the interior of the dust hopper 131 to facilitate smooth guiding of dust into the dust hopper 131.

When the dry type cleaning machine is used, waste gas discharged from the dry type cleaning machine enters the airflow channel from the air inlet pipeline 120 through the connecting hose 124c, the waste gas moves downwards in a spiral mode under the guiding action of the pipe wall of the spiral vortex pipe 124, dust in the waste gas is thrown outwards under the action of cyclone centrifugal force and separated from gas, and the separated dust falls on the lower pipe wall of the spiral vortex pipe 124 and finally slides downwards along the lower pipe wall of the spiral vortex pipe 124 and falls into the dust hopper 131. The clean gas descends to the lower end of the spiral pipe wall to form an inner rotational flow, flows upwards and is discharged from the exhaust pipe 111.

When the airflow increases, the pressure of the airflow channel in the spiral scroll 124 also increases, so that the spiral scroll 124 expands and stretches in the vertical direction, the upper end of the spiral scroll 124 moves upward, and the rotating ring 123 and the supporting rod 141 are driven by the connecting piece to move upward synchronously, that is, the toothed ring and the gear 128 cannot be engaged.

As the usage time increases, dust accumulates on the inner wall of the spiral scroll 124, and the roughness of the inner wall of the spiral scroll 124 increases, so that the dust removal efficiency decreases, and the detection net 124a gradually blocks. At this time, the spiral scroll 124 expands no matter the flow rate of the gas is increased, the upper end of the spiral scroll 124 drives the rotating ring 123 and the supporting rod 141 to move upwards synchronously through the connecting piece, so that the toothed ring is meshed with the gear 128, the toothed ring drives the supporting rod 141 to rotate around the axis of the supporting rod 141 through the bevel gear ring and the bevel gear 143, and the supporting rod 141 drives the knocking wheel 142 thereon to knock the spiral scroll 124 when rotating, so that the spiral scroll 124 vibrates, dust on the inner wall of the spiral scroll 124 is removed, and the reduction of the dust removal efficiency is avoided.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
