Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, and more specifically, to a pulse filter cartridge type dust removal tank. Background Art

[0002] The pulse filter cartridge dust collector is a dust removal device that can automatically clean. It uses a pulse structure to regularly clean the dust adsorbed on the filter cartridge to extend the service life of the filter cartridge. The dust ejected from the filter cartridge is very easy to fly in the inner cavity of the dust collector, causing the dust to adhere to the inner wall of the dust collector and be difficult to remove, which affects the dust removal efficiency.

[0003] The Chinese utility model patent with application number 202321888602.6 discloses a cartridge-type pulse dust collector, in which a fan for inward blowing is arranged on the dust collector, and the power of the fan is transmitted to the knocking head through the transmission assembly. The knocking head performs reciprocating motion, and repeatedly hammers the wall of the dust collector cavity through the attraction and release of the knocking head and the magnet, so that the dust on the cavity wall is shaken off and collected, thereby improving the dust collection rate. However, the repeated attraction and release of the magnet causes the spring to be repeatedly stretched and compressed. After long-term use, the spring is prone to fatigue and the tension is reduced, thereby affecting the strength of the knocking and even failing to complete the knocking action, resulting in reduced dust collection efficiency.

[0025] See also Figure 1-6 , the utility model provides the following technical solutions:

[0026] A pulse filter cartridge dust collector comprises a dust collector body 1, a dust collecting barrel 2 is movably mounted on a dust outlet 11 of the dust collector body 1, a filter screen 24 is arranged at one end of the dust collecting barrel 2 away from the dust outlet 11, a dust collecting mechanism 3 is connected to one end of the dust collecting barrel 2 away from the dust outlet 11, and the dust collecting mechanism 3 sucks air from the dust collector body 1 through the dust collecting barrel 2, thereby adsorbing dust in the tank body and collecting it in the dust collecting barrel 2;

[0027] A mounting bracket 5 is installed in the middle of the side wall of the dust removal tank body 1, and a knocking mechanism 4 is installed on the mounting bracket 5. The hammer head 43 of the knocking mechanism 4 can knock on the corresponding side wall of the dust removal tank body 1. When the pulse device of the dust removal tank body 1 impacts the filter cartridge, the knocking mechanism 4 cooperates and knocks on each side wall of the dust removal tank body 1 synchronously, thereby preventing dust from being adsorbed on the inner wall of the dust removal tank body 1, thereby improving the cleanliness of the dust removal tank and the dust collection efficiency.

[0028] The knocking mechanism 4 includes a motor 41, which is mounted on a mounting bracket 5. The output shaft of the motor 41 points to the side wall of the corresponding dust removal tank body 1 and is fixedly connected to a connecting shaft 42. A hammer head 43 is coaxially mounted on the connecting shaft 42. When the motor 41 drives the connecting shaft 42 to rotate, the hammer head 43 is driven by the connecting shaft 42 to rotate synchronously. At the same time, the hammer head 43 can slide axially on the connecting shaft 42. A slide groove 48 is provided on the outer surface of the hammer head 43. A limit block 46 is fixed on the mounting bracket 5. When the limit block 46 slides in the slide groove 48, the hammer head 43 moves toward or away from the side wall of the corresponding dust removal tank body 1, thereby knocking on the side wall of the dust removal tank body 1.

[0029] A spring 44 is sleeved on the connecting shaft 42, one end of the spring 44 is connected to the motor 41, and the other end of the spring 44 is connected to a push block 45, which is slidably sleeved on the connecting shaft 42, and the end face of the push block 45 facing away from the spring 44 is in contact with the hammer head 43, and a rubber pad 47 is installed on the side of the hammer head 43 facing the dust removal tank body 1. The hammer head 43 contacts the side wall of the dust removal tank body 1 through the rubber pad 47, which reduces noise, and the rubber pad 47 can change the rigid contact into flexible contact, preventing the side wall of the dust removal tank body 1 and the hammer head 43 from being damaged during long-term use. When the hammer head 43 moves in the direction away from the dust removal tank body 1, it pushes the push block 45 to compress the spring 44. When the hammer head 43 is released, the spring 44 pushes the hammer head 43 to quickly reset through the push block 45, so that the side wall of the dust removal tank body 1 can be knocked.

[0030] The limit block 46 includes a movable bracket 461 and a connecting head 462. The movable bracket 461 and the connecting head 462 are respectively arranged on both sides of the hammer head 43. The side of the movable bracket 461 facing the hammer head 43 is set to an arc shape. The hammer head 43 can rotate or slide on the movable bracket 461, and the connecting head 462 slides in the slide groove 48. The movable bracket 461 and the connecting head 462 are relatively arranged, which can provide stable support and limitation for the hammer head 43, ensure the coaxiality of the hammer head 43 during the movement process, and reduce the wear of the mechanism.

[0031] The slide groove 48 includes a retraction groove 481, which is spirally arranged around the outer circumference of the hammer head 43. The hammer head 43 is wrapped by the retraction groove 481 for 3 / 4 of the circumference. When the motor 41 drives the hammer head 43 to rotate and the connector 462 is in the retraction groove 481, the hammer head 43 is pushed by the connector 462 to move away from the dust removal tank body 1, and the spring 44 is compressed at the same time.

[0032] The end of the retraction groove 481 away from the motor 41 is connected to the retaining groove 483, which is in the shape of an arc concentric with the hammer head 43. The hammer head 43 is wrapped by the retaining groove 483 for 1 / 4 of the circumference. When the connector 462 is in the retaining groove 483, the relative position of the hammer head 43 and the dust removal tank body 1 remains unchanged. At this time, the spring 44 is compressed to the limit and has the maximum elastic potential energy. If the hammer head 43 is released at this time, the hammer head 43 is pushed by the spring 44 to knock the dust removal tank body 1 to realize the function;

[0033] One end of the retaining groove 483 facing away from the retraction groove 481 is connected to the hammer groove 482, and the other end of the hammer groove 482 is connected to the end of the retraction groove 481 facing the motor 41. The hammer groove 482 is opened along the axial direction of the hammer head 43. When the connecting head 462 slides to the hammer groove 482, the motor 41 pauses, and the spring 44 pushes the hammer head 43 to reset quickly, so that the hammer head 43 hits the side wall of the dust removal tank body 1 to achieve knocking, thereby shaking off the accumulated dust on the inner wall.

[0034] The dust collecting barrel 2 includes an outer barrel wall 21, a filter screen 24 is installed at the bottom of the outer barrel wall 21, and a filter barrel 23 is installed in the outer barrel wall 21. The built-in filter barrel 23 increases the area of ​​air circulation, that is, the dust has a larger adsorption area, which improves the dust collecting effect. A plurality of blocks 22 are symmetrically arranged on the outer wall of the outer barrel wall 21, and the plurality of blocks 22 are arranged at the upper and lower ends of the outer barrel wall 21. A sealing ring 13 is installed in the dust discharge port 11, and the sealing ring 13 is sealed and connected with the opening of the dust collecting barrel 2. A plurality of card grooves 12 are evenly opened on the dust discharge port 11, and a plurality of card blocks 22 at the upper end of the outer barrel wall 21 are respectively engaged with a plurality of card grooves 12; the engagement of the card blocks 22 with the card grooves 12 can realize the rapid disassembly and assembly of the dust collecting barrel 2, thereby facilitating the cleaning of the dust collection.

[0035] The dust suction mechanism 3 includes a fan, and a connecting pipe 31 is installed at the air inlet of the fan. The other end of the connecting pipe 31 is movably sleeved on the dust collecting barrel 2. A plurality of card slots 33 are evenly opened on the connecting pipe 31. A plurality of card blocks 22 at the lower end of the outer cylinder wall 21 are respectively engaged with the plurality of card slots 33. A sealing ring 32 is installed in the connecting pipe 31. The sealing ring 32 is sealed and connected to the bottom end of the outer cylinder wall 21. The connecting pipe 31 can be conveniently disassembled and assembled with the dust collecting barrel 2, which is convenient for cleaning the collected dust. The fan is used to suck air from the bottom of the dust collecting barrel 2 to the inside of the dust removal tank body 1, which can promote the movement of dust in the dust removal body 1, so that it is adsorbed in the dust collecting barrel 2, thereby improving the dust cleaning effect.

[0036] Specifically, a sliding groove 48 of a specific shape is provided on the outer surface of the hammer head 43 of the knocking mechanism 4. When the hammer head 43 rotates, the connecting head 462 moves in the sliding groove 48. When the connecting head 462 is in the retraction groove 481, it drives the hammer head 43 to move away from the dust removal tank body 1 and compresses the spring 44. When the connecting head 461 is in the retaining groove 483, the relative position of the hammer head 43 and the dust removal tank body 1 is maintained, and the compression state of the spring 44 is maintained. When the connecting head 461 is in the hammering groove 482, the hammer head 43 is ejected under the action of the spring 44 to reset, thereby hammering the side wall of the dust removal tank body 1 to shake off the dust on it. During the process, the spring 44 is only in a compressed and reset state, the deformation is relatively small, it is not easy to be fatigued and damaged, and the service life is longer.
