Description

Technical Field

[0001] The utility model relates to the technical field of black smoke particle traps, in particular to an automatic switch actuator for a bypass valve of a black smoke particle trap. Background Art

[0002] Factory production requires the use of power equipment such as diesel engines, which require black smoke particulate collectors to collect and treat black smoke exhaust. Existing black smoke particulate collectors generally use filter cartridges to filter the flue gas. After a period of use, many smoke particles will adhere to the outer end of the filter cartridge, causing blockage, which restricts internal airflow and generates high pressure. If the flue gas cannot be discharged in time, it can easily become dangerous. The internal temperature of the collector is high and the environment is poor. Existing solenoid valves are not suitable for the collector, and conventional regulating mechanisms cannot effectively control the valve opening and closing. Therefore, a stable and adjustable bypass valve automatic opening and closing actuator is needed. Utility Model Content

An air inlet port for introducing black smoke gas into the purification chamber is provided on one side of the box body, and an exhaust port for exhausting air is provided on the other side. The purification chamber is provided with several groups of filter elements for filtering the air, and the filtered air is introduced into the guide chamber through the filter elements;

[0006] The bypass valve is installed on the partition. The bypass valve includes a valve cylinder fixedly installed on the corresponding through hole of the partition, a valve plate arranged corresponding to the valve cylinder, and an actuator that drives the valve plate to rotate. The actuator includes a spring seat fixedly arranged on the upper end of the outer side of the valve plate, a rotating shaft that drives the spring seat to rotate, and a driving member arranged at the outer end of the box to control the rotation of the rotating shaft. The valve plate can be elastically moved by the spring seat to avoid hard squeezing of the valve plate and the valve cylinder when the valve plate rotates.

[0007] As a further solution of the utility model:

[0008] The bypass valve is installed on the side of the partition facing the exhaust pipe outlet, and the side of the valve cylinder facing the valve plate is a stepped hole structure. When the valve plate is closed, it is attached to the step column of the valve plate to increase the sealing performance between the valve plate and the valve cylinder.

[0009] As a further solution of the utility model:

The purification chamber 12 is provided with a plurality of groups of filter elements 16 for filtering the air, and the filtered air is introduced into the guide chamber 13 through the filter elements 16;

[0030] The bypass valve 2 is installed on the partition 11.

[0031] In this embodiment, the bypass valve 2 is installed on the side of the partition 11 facing the exhaust pipe port 15, and the side of the valve cylinder 21 facing the valve plate 22 is a stepped hole structure. When the valve plate 22 is closed, it is attached to the step column of the valve plate 22 to increase the sealing performance between the valve plate 22 and the valve cylinder 21.

[0032] A slider 25 is slidably installed in the spring seat 23, and a guide rod 26 is provided in the spring seat 23 corresponding to the slider 25. The slider 25 is sleeved on the outer end of the guide rod 26 to move up and down along the guide rod 26.

The lower end of the first spring 27 is abutted on the slider 25, and the upper end of the first spring 27 is abutted on the upper end of the inner cavity of the spring seat 23, so that the slider 25 can move elastically in the inner cavity of the spring seat 23; the two sides of the slider 25 are fixedly connected to the rotating shaft 24, and corresponding sliding grooves 28 are opened on both sides of the spring seat 23 corresponding to the rotating shaft 24. Specifically, the rotating shaft 24 drives the spring seat 23 and the valve plate 22 to rotate through the slider 25. When the valve plate 22 rotates, the outer side of the upper end of the valve plate 22 will abut against the outer wall of the valve cylinder 21. The valve plate 22 will move downward along the guide rod 26 through the spring seat 23, so that the valve plate 22 elastically moves a little, thereby staggering with the valve plate 22 to avoid hard contact with the valve plate 22.

Specifically, the adjustment seat 31 is connected to the electric push rod 3 via the elastically arranged screw 34, so that the rotating shaft 24 can drive the valve plate 22 to rotate, thereby enabling elastic adjustment. When the internal pressure of the purification chamber 12 is too high, the valve plate 22 can push the rotating shaft 24 to rotate, and the rotating shaft 24 can pull the adjustment seat 31 upward through the connecting plate 33 to relieve pressure.
