Description

TECHNICAL FIELD

[0001] The utility model relates to a cloth bag dust collector technical field, specifically related to a cloth bag dust collector of automatic cleaning. BACKGROUND

[0002] The bag type dust collector is a dry type dust filtering device, which is suitable for capturing fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt. The dust in the dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag type dust collector, the dust with large particles and high specific gravity is settled down due to the action of gravity and falls into the ash bucket. The gas containing fine dust is filtered through the filter material, and the dust is blocked, so that the gas is purified. The existing cloth bag dust collector usually uses a pulse device to backflush the filter bag, so that the filter bag is cleaned. However, in the actual use process, due to the fast airflow of backflushing, the temperature will be reduced in a short time, so that condensation will be formed on the filter bag due to the temperature difference, and dust clumps will appear on the outer surface of the cloth bag, thereby blocking the filter bag. In addition, during the installation process of the filter bag, the gap between the installation hole and the filter bag is small, so that the edge of the installation hole is in contact with the filter bag, which causes the filter bag to be worn. When disassembling and cleaning, the dust on the outer side of the filter bag will rub against the outer side of the installation hole, which will cause dust. Therefore, a cloth bag dust collector capable of automatic cleaning is needed to solve the above problems. SUMMARY

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] See Figures 1-5 The present invention provides an automatically cleaning bag filter, including a filter bag mounting frame 1, a filter bag mounting plate 2 detachably mounted on the top of the filter bag mounting frame 1; multiple filter bag bodies 3 are arranged in an array on the filter bag mounting plate 2 with their openings facing upwards; an array of mounting rings is provided at the bottom of the filter bag mounting frame 1, the array of mounting rings including multiple mounting rings 11 arranged in an array, the positions of the mounting rings 11 corresponding one-to-one with the positions of the filter bag bodies 3, and adjacent mounting rings 11 are fixed by a connecting block 17;

[0028] A counterweight 5 is fixedly installed on each of the left and right sides of the mounting ring array. All mounting rings 11 located on the left and right edges of the mounting ring array are fixedly installed on the counterweight 5 on the corresponding side by a connecting block 17. A lifting rope 6 is fixedly installed on the counterweight 5. A motor 7 is fixedly installed on the upper end of each of the left and right sides of the filter bag mounting frame 1, and the output shafts of the two motors are horizontally opposite each other. The upper end of the lifting rope 6 is connected to the output shaft of the corresponding motor 7.

[0029] A rotating ring 4 is rotatably installed within each mounting ring 11. Multiple mounting grooves 9 are evenly distributed circumferentially on the inner wall of the rotating ring 4. Multiple cleaning rods 8 are rotatably installed within each mounting groove 9, with the axis of rotation of the cleaning rod 8 parallel to the tangent of the rotating ring 4. The upper end of the cleaning rod 8 is rotatably mounted within the upper end of the mounting groove 9 via the rotating shaft. A torsion spring 10 is installed on one end of the rotating shaft of the cleaning rod 8, with two torsion arms of the torsion spring 10 respectively mounted on the side walls of the cleaning rod 8 and the mounting groove 9, maintaining a certain angle between the cleaning rod 8 and the mounting groove 9. The diameter of the circle formed by the lower ends of all the cleaning rods 8 within the same rotating ring 4 is smaller than the diameter of the lower cross-section of the filter bag 3.

[0030] The working process and principle of the above technical solution are as follows:

[0031] In use, the starter motor 7 drives the winding wheel 15 to rotate, thereby winding up the lifting rope 6, causing the counterweight 5 and mounting ring 11 array to rise as a whole. During the rising process, the lower ends of all filter bag bodies 3 pass through the space enclosed by their corresponding cleaning rods 8. Since the diameter of the circle enclosed by the lower ends of the cleaning rods 8 within the same rotating ring 4 is smaller than the diameter of the cross-section of the lower end of the filter bag 3, the cleaning rods 8 can fit against the surface of the filter bag body 3 during the lifting process. They surround the filter bag body 3 from the circumference and exert an upward frictional force on it, achieving scraping and cleaning of the surface of the filter bag body 3 from bottom to top. At the same time, due to the rotational setting of the rotating ring 4 relative to 11, the contact points between the cleaning rods 8 and the filter bag body 3 are random when the rotating ring 4 rises, which can effectively prevent jamming during the movement.

[0032] When the mounting ring array 11 rises to the top of the filter bag body 3, the motor 7 reverses, driving the winding wheel 15 to rotate, thus gradually loosening the lifting rope 6. Under the gravity of the counterweight 5, the counterweight 5 and the mounting ring array 11 descend as a whole. During the descent, the cleaning rod 8 exerts a downward frictional force on the surface of the filter bag body 3, achieving a secondary cleaning by scraping the surface of the filter bag body 3 from top to bottom, until the mounting ring array 11 rises to the bottom of the filter bag body 3 and disengages. At this point, the cleaning rod 8 returns to its initial position under the rebound action of the torsion spring 10.

[0033] During the above process, due to the setting of the torsion spring, the cleaning rod 8 can be in close contact with the surface of the filter bag body 3 under the action of torque during the rising and falling process, making the cleaning more efficient.

[0034] In a preferred embodiment of this utility model, the filter bag body 3 is a frustum-shaped cone with a diameter decreasing from top to bottom. All filter bag bodies 3 are mounted on the filter bag mounting plate 2 via mounting holes arranged in an array on the plate, with the mounting holes fitting the upper ends of the filter bag bodies 3. This structural design reduces the probability of the filter bag bodies 3 colliding with the mounting holes during installation and makes it less likely to generate dust during disassembly.

[0035] In a preferred embodiment of this invention, the lower end of the lifting rope 6 is divided into two strands, both of which are fixedly mounted on the counterweight 5. This structure enables the counterweight 5 to drive the mounting ring array to rise and fall stably, increasing stability.

[0036] In a preferred embodiment of this utility model, a mounting bracket 14 is fixedly installed on the left and right sides of the upper end of the filter bag mounting frame 1, and the motor 7 is fixedly installed on the mounting bracket 14 on the corresponding side. A winding wheel 15 is fixedly installed on the output shaft of the motor 7, and the upper end of the lifting rope 6 is fixed on the winding wheel 15.

[0037] In a preferred embodiment of this invention, the mounting bracket 14 and the motor 7 are both shielded by a shielding frame 16, which is fixedly mounted on the filter bag mounting frame 1. This design prevents dust from falling in and is aesthetically pleasing.

[0038] In a preferred embodiment of this utility model, a conical shielding ring 12 is detachably installed on the upper end of the mounting ring 11. The conical shielding ring 12 shields the rotating ring 4 and does not contact the rotating ring 4. This design can prevent dust from falling in and is aesthetically pleasing.

[0039] In a preferred embodiment of this utility model, a conical block 13 is fixedly installed on the upper end of the connecting block 17, which improves the sealing between the conical shielding ring 12 and the mounting ring 11, making it difficult for dust to accumulate on the rotating ring 4 and the mounting ring 11, thereby increasing the stability of use.
