Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust collectors, in particular to an industrial dust collector with online maintenance. Background Art

[0002] In order to clean the dust in the air around the workshop or equipment, the air needs to be extracted through a fan and filtered during the extraction process to prevent the dust from being directly discharged outdoors and causing environmental pollution. Valuable dust can also be recovered for secondary use.

[0003] Small dust collectors can filter dust from the air through filters. During the dust removal process, the filter mesh is constantly covered with dust, reducing airflow and, consequently, dust removal efficiency. This often requires shutting down the machine and removing the filter for maintenance. This cumbersome operation, such as replacing the filter or cleaning the dust off the filter surface, interferes with normal dust removal. Utility Model Content

[0004] The purpose of the utility model is to provide an industrial dust collector with online maintenance, which can perform online maintenance on the air filter and realize uninterrupted dust removal.

[0005] To achieve this purpose, the present invention adopts the following technical solutions:

[0014] Wherein, a first flange is provided at the rear end of the cylinder, and a second flange is provided at the front end of the cylinder.

[0015] The beneficial effects of the utility model are as follows: an industrial dust collector with online maintenance filters the air flow in the cylinder through the air filter, and the dust is blocked on the rear side of the air filter. The driving ring is periodically moved back and forth quickly to hit the driving rod, so that the floating ring and the air filter can move back and forth quickly.

[0018] The following combination Figure 1~Figure 2 The technical solution of the present utility model is further illustrated by specific embodiments.

[0019] like Figure 1 The online maintained industrial dust collector shown includes: a cylinder 1, an air filter 5, a floating ring 4 and a drive ring 3. A fixed ring 11 is concentrically arranged in the cylinder 1. In this embodiment, the outer wall of the fixed ring 11 is welded and fixed to the inner wall of the cylinder 1, and the structure is stable. The outer wall of the fixed ring 11 has good air tightness to avoid air leakage problems.

[0020] The floating ring 4 is arranged in the cylinder 1 and is located behind the fixed ring 11. The air filter 5 is arranged in the floating ring 4. The air filter 5 is fixed in the floating ring 4 by screws or pressing sheets and moves with the floating ring 4.

[0021] In this embodiment, the rear end of the cylinder 1 is provided with a first flange 13, which is connected to a fan or an air inlet pipe to deliver air into the cylinder 1. After being filtered by the air filter 5, the clean air is discharged through the front end of the cylinder 1. The front end of the cylinder 1 is provided with a second flange 14, which can be connected to an exhaust pipe to discharge the air outdoors.

[0022] Guide posts 6 are arranged at intervals on the back of the fixed ring 11 and penetrate the floating ring 4 backward. The floating ring 4 is provided with guide holes corresponding to the guide posts 6 one by one. The guide posts 6 guide the floating ring 4 during axial movement.

[0023] like Figure 2 As shown, the guide post 6 is provided with a stopper 16 located behind the floating ring 4 to limit the rearward movement of the floating ring 4 and prevent it from falling off. In this embodiment, the outer circumference of the floating ring 4 is provided with an annular groove, and the annular groove is provided with a sealing ring 17 that contacts the inner wall of the cylinder 1. This prevents airflow from passing through the gap between the outer circumference of the floating ring 4 and the inner wall of the cylinder 1, ensuring that the airflow is filtered by the air filter 5.

[0024] An elastic support body 7 is provided between the limit piece 16 and the floating ring 4 to elastically support and reset the floating ring 4 after it moves backward. Figure 1 As shown, the floating ring 4 is ensured to fit with the fixed ring 11, thereby improving the structural stability during the dust removal process. In this embodiment, the elastic support body 7 is a spring and is sleeved on the guide column 6, so that the position is stable.

[0025] The driving ring 3 is arranged in the cylinder 1 so as to be movable axially along the cylinder 1 and is located in front of the fixed ring 11. Several driving rods 8 are arranged at intervals on the front of the floating ring 4, which penetrate the fixed ring 11 and point to the driving ring 3. When the driving ring 3 moves backward, it can hit the driving rod 8 to achieve rapid reciprocating movement of the floating ring 4 and the air filter 5. Vibration and movement inertia are used to make the dust attached to the rear side of the air filter 5 fall off, and automatic maintenance is performed.

[0026] A linear reciprocating drive mechanism 18 connected to the drive ring 3 is symmetrically arranged on the inner wall of the cylinder 1. In this embodiment, the linear reciprocating drive mechanism 18 adopts an oil cylinder, an air cylinder or a hydraulic cylinder, and can be telescopically controlled by a PLC. The linear reciprocating drive mechanism 18 is moved regularly, and the drive ring is quickly moved backward to complete multiple strikes on the drive rod 8, thereby maintaining the air filter 5 online and restoring the filtering effect of the air filter 5.

[0027] An ash drop hole 12 is provided at the bottom of the cylinder 1, located behind the floating ring 4. Dust on the rear side of the air filter 5 falls off and enters the ash drop hole 12 by gravity, preventing it from accumulating in the cylinder 1. A first pipe joint 9 communicating with the ash drop hole 12 is provided at the bottom of the cylinder 1. A dust collection box 10 is provided below the cylinder 1. A second pipe joint 2 is provided at the top of the dust collection box 10. A pipe 15 is provided between the first and second pipe joints 2. Dust in the ash drop hole 12 enters the dust collection box 10 through the pipe 15 for centralized processing. The dust collection box 10 is large in size and can store more dust, extending maintenance intervals.

[0028] In this embodiment, the pipe 15 is a flexible bellows, which can reduce the transmission of vibration in the cylinder 1 to the dust collecting box 10, maintain the stability of the dust collecting box 10, and reduce the problem of dust in the dust collecting box 10.

[0029] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
