Description

Technical Field

[0001] The present invention relates to the technical field related to bag dust collectors, and in particular to a bag dust collector that is easy to replace. Background Art

[0002] Bag dust collector is a kind of efficient dry dust removal equipment, which is widely used in various industrial fields to capture and remove dust particles in air or gas. Its working principle is to use filter bags (usually made of fabric) to filter dust-laden gas, so that the dust remains on the surface of the filter bag, while the clean gas is discharged through the filter bag.

[0003] The publication number is CN212491992U. A bag dust removal device includes a box body and a flower plate fixedly arranged in the box body. An air inlet is arranged on the side wall of the box body below the flower plate, and the air inlet is covered with a first solenoid valve. A discharge port is arranged at the lower end of the box body, and the discharge port is covered with a second solenoid valve. An air outlet pipe is arranged on the box body above the flower plate, and the air outlet pipe is connected to an air pump. A plurality of through holes are arranged on the flower plate, and a frame is passed through the through holes. A filter bag is sleeved on the frame. The frame includes a connecting section, a bending section and a supporting section from top to bottom. The radius of the bending section is larger than that of the connecting section and the supporting section. A fixing ring is detachably connected to the connecting section. The fixing ring and the upper surface of the flower plate clamp the filter bag together, and the bending section and the lower surface of the flower plate clamp the filter bag together. The utility model clamps the cloth bag together by the fixing ring and the bending section, thereby improving the stability of the cloth bag on the frame, which helps to protect the air pump. The bag dust removal device in the above technology is not easy to replace the filter bag due to its own design characteristics. During the long-term use of the filter bag, the dust filtering effect is reduced, thereby reducing the efficiency of the bag dust collector in filtering the air. Summary of the invention

[0004] The present invention solves the problems in the related art and proposes a bag dust collector that is easy to replace, aiming to solve the problem that the bag dust collector in the current technology is not easy to replace the filter bag due to its own design characteristics. During the long-term use of the filter bag, the filtering effect of the dust is reduced, thereby reducing the efficiency of the bag dust collector in filtering the air.

[0005] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: a bag dust collector that is easy to replace, comprising a dust removal box, movable wheels respectively arranged on the lower end surface of the dust removal box, a high-pressure fan fixedly arranged on the upper end surface of the dust removal box, an exhaust port arranged next to the high-pressure fan and connected to the dust removal box, a bag assembly arranged in the inner cavity of the dust removal box relative to the exhaust port, an inspection door hingedly arranged on the front end surface of the dust removal box and relative to the bag assembly, a dust collecting box arranged on the lower end surface of the bag assembly, an air inlet arranged at one end of the dust removal box, and a controller arranged on the front end surface of the dust removal box and electrically connected to the high-pressure fan.

[0006] By adopting the above technical solution, the high-pressure fan is started through the controller, and the high-pressure fan creates a negative pressure state in the inner cavity of the dust removal box. The outside air enters the dust removal box through the air inlet. The air entering the dust removal box is first filtered by the bag assembly, and the filtered air is discharged through the exhaust port. The filtered impurities are automatically collected in the dust box due to their own weight, and the impurities collected in the dust box can be cleaned regularly.

The first support plate and the second support plate are connected by an elastic support piece, which makes it convenient to press the second support plate to make the mounting sleeve detach from the outer periphery of the filter bag. The user lifts up the limit baffle, and the limit baffle removes the filter bag from the mounting sleeve with the filter bag. Such a design improves the efficiency of the staff in detaching the filter bag, and avoids removing the support sleeves from the filter bag one by one, and then removing the filter bags from the mounting sleeve one by one.

[0009] Optionally, the connecting member includes sliders respectively arranged on both sides of the first support plate and the second support plate and arranged relative to the first support frame and the second support frame, and sliding grooves arranged on the first support frame and the second support frame and adapted to the sliders, and the sliders are fixedly connected to the first support plate and the second support plate, respectively.

[0010] By adopting the above technical solution, the complementary effects between the slider and the slide groove make it easy to remove the bag assembly from the dust removal box as a whole, making it easier for the staff to replace and remove the filter bag.

[0011] Optionally, the elastic support member includes support tubes fixedly arranged at the four corners of the first support plate, a sliding rod slidably connected to the support tube and fixedly connected to the four corners of the lower end of the second support plate, and a support spring arranged on the outer periphery of the sliding rod, one end of the support spring is fixedly connected to the end of the support tube away from the end connected to the first support plate, and the other end of the support spring is fixedly connected to the lower end surface of the second support plate.

The user lifts up the limit baffle plate, and the limit baffle plate removes the filter bag from the mounting sleeve.

[0013] Optionally, the outer diameter of the second support plate is smaller than the outer diameter of the limiting baffle.

[0014] By adopting the above technical solution, it is convenient for the staff to press the second support plate.

[0015] Optionally, the mounting sleeve is configured to be made of a non-woven fabric material or a fiber material.

[0016] By adopting the above technical solution, such a design facilitates the bending of the installation sleeve, thereby avoiding position interference caused by the installation sleeve when pressing the second support plate.

[0017] Optionally, the support sleeve includes a support ring and support rods evenly arranged on the lower end surface of the support ring, and the support ring is fixedly connected to the limit stop ring.

[0018] By adopting the above technical solution, the support rod can easily support the inner wall of the filter bag, thereby effectively ensuring the efficiency of the filter bag in filtering air.

[0019] Optionally, the fixing member includes a limiting protrusion arranged on one end of the filter bag relative to the limiting baffle and a limiting groove arranged on the lower end surface of the support ring and adapted to the limiting protrusion.

[0020] By adopting the above technical solution, the complementary effects between the limit slot and the limit protrusion make it easy to connect the filter bag with the support sleeve. The user lifts up the limit baffle, and the limit baffle removes the filter bag from the installation sleeve. This design improves the efficiency of the staff in detaching the filter bag, and avoids removing the support sleeve from the filter bag one by one, and then removing the filter bag from the installation sleeve one by one.
