Description

Technical Field

[0001] The invention relates to the technical field of pipeline resistance balance adjustment, and in particular to an automatic pressure-regulating wear-resistant resistance balancer and a pipeline system. Background Art

[0002] Many factories are equipped with centralized dust collector systems. The centralized dust collector network is complicated and has many branch pipes. In order to ensure the resistance balance of each branch pipe, the conventional practice is to set regulating valves on the branch pipes and adjust the valve opening to achieve resistance balance in the entire network. Due to the large number of valves, the debugging workload is large, and the uneven airflow causes great wear on the valve plate. After long-term operation, the valve is seriously damaged, the system resistance balance is broken, and it cannot operate normally. In recent years, by adding a resistance balancer and adjusting the parameters of the resistance balancer to change the resistance distribution in the system, the airflow can be evenly distributed, maintenance costs can be reduced, and the operating efficiency of the entire dust removal system can be improved.

[0003] The balanced tube resistance balancer in the prior art places the balanced tube at the center of the short tube, connects it to the short tube with a circular connecting plate, and sets flanges at both ends to access the pipeline. However, the use of annular baffles may cause dust accumulation when used in horizontal flues, and the wear resistance is poor. Maintenance requires shutdown or replacement with a shut-off valve, and the maneuverability of resistance adjustment is poor. Summary of the invention

[0004] The present application proposes an automatic pressure-adjusting wear-resistant resistance balancer and pipeline system, which can adjust the balancer resistance online at any time, increase the cylindrical flow design, and use wear-resistant polytetrafluoroethylene material for the internal sliding rod to reduce the wear rate and increase the service life; the device has a good seal and does not leak smoke, and the pipeline pressure can be adjusted online at any time, and the pressure value can be adjusted at will.

[0005] To this end, the present application provides an automatically pressure-adjustable wear-resistant resistance balancer, comprising an inlet pipe body and an outlet pipe body, wherein the ends of the inlet pipe body and the outlet pipe body that are close to each other are connected with a square shell through a square circle joint, and the square shell is connected with the inlet pipe body and the outlet pipe body. A resistance balancing mechanism is provided inside the square shell, and a graded driving mechanism for driving the resistance balancing mechanism to operate is provided on the outside of the square shell. Pressure detection mechanisms are provided at both the inlet pipe body and the outlet pipe body, and the pressure detection mechanism is electrically connected to a controller, and the controller is electrically connected to the graded driving mechanism.

[0006] By adopting the above technical solution: when the smoke enters the inlet pipe body and reaches the square shell, the smoke flow pressure can be adjusted through the resistance balancing mechanism, and the pressure difference signal between the inlet pipe body and the outlet pipe body is detected by the pressure detection mechanism. After being processed by the controller, the graded driving mechanism is driven to operate, and the graded driving mechanism can drive the resistance balancing mechanism to operate to adjust the pressure value of the smoke flow.

[0007] Optionally, the ends of the inlet pipe body and the outlet pipe body that are away from each other are both provided with connecting flanges.

[0008] By adopting the above technical solution: by setting a connecting flange, it is convenient to install the device on the flue gas duct.

[0009] Optionally, the resistance balancing mechanism includes a limiting component arranged inside the square shell and a balancing component slidingly inserted into the limiting component via an elastic component.

[0010] Optionally, the limiting assembly includes a plurality of limiting cylinders fixedly connected to the square shell, the balancing assembly includes a sliding rod slidably disposed in the limiting cylinder, and the elastic assembly includes a reset spring disposed between the limiting cylinder and the sliding rod.

[0011] By adopting the above technical solution: the sliding rod can be driven by the graded driving mechanism to penetrate into the flue gas flow, thereby blocking the flue gas flow and increasing the pressure of the flue gas flow. Of course, driven by the graded driving mechanism, the insertion depth and number of the sliding rods can be changed, thereby arbitrarily changing the pressure of the flue gas flow.

[0012] Optionally, the grading drive mechanism includes a mounting frame connected to the outside of the square shell, the mounting frame is connected to a mounting plate, the mounting plate is provided with a telescopic drive assembly, the telescopic drive assembly is connected to a top-connecting hole plate, and also includes a grading plate slidably arranged in the top-connecting hole plate, the top-connecting hole plate is provided with a pushing assembly for driving the grading plate to move inside the top-connecting hole plate.

[0013] Optionally, the top-connecting hole plate is provided with a plurality of through holes corresponding to the sliding rods, and the diameter of the through holes is larger than the outer diameter of the sliding rods, and the sliding rods can be arranged in multiple rows and multiple layers.

[0014] Optionally, the telescopic drive assembly includes an electric telescopic rod disposed on the mounting plate, and an output shaft of the electric telescopic rod is connected to the top-connecting hole plate.

[0015] Optionally, the pushing assembly includes a driving motor connected to the top-connecting hole plate via a connecting rod, a gear is connected to the output shaft of the driving motor, and a rack meshing with the gear is provided on the grading plate.

[0016] By adopting the above technical solution: the telescopic driving assembly can drive the top-connected hole plate to move toward the center of the square shell, the driving motor can drive the gear to rotate, and through the setting of the rack, the grading plate can be driven to slide inside the top-connected hole plate. When more sliding rods need to be inserted, the grading plate can move a greater distance inside the top-connected hole plate, so that more perforations can be blocked. At this time, more sliding rods cannot pass through the top-connected hole plate and are pushed by the top-connected hole plate to move toward the center of the square shell.

[0017] Optionally, the pressure detection mechanism includes pressure sensors arranged at the inlet and outlet of the tube body.

[0018] A pipeline system in the present application includes a plurality of flue gas ducts, each of which is provided with the above-mentioned automatic pressure-regulating wear-resistant resistance balancer.

[0019] The working principle and beneficial effects of this application are:

[0020] 1. When the flue gas enters the inlet pipe body and reaches the square shell, the flue gas flow pressure can be adjusted through the resistance balance mechanism. The pressure difference signal between the inlet pipe body and the outlet pipe body is detected by the pressure detection mechanism. After being processed by the controller, the graded driving mechanism is driven to operate. The graded driving mechanism can drive the resistance balance mechanism to operate and adjust the pressure value of the flue gas flow.

[0021] 2. The sliding rod in the present application can be driven by the graded driving mechanism to penetrate into the flue gas flow, thereby blocking the flue gas flow and increasing the pressure of the flue gas flow. Of course, driven by the graded driving mechanism, the insertion depth and number of the sliding rods can be changed, thereby changing the pressure of the flue gas flow at will.

[0022] 3. The telescopic drive assembly can drive the top-connected orifice plate to move toward the center of the square shell, and the drive motor can drive the gear to rotate. Through the setting of the rack, the grading plate can be driven to slide inside the top-connected orifice plate. When more sliding rods need to be inserted, the grading plate can move a greater distance inside the top-connected orifice plate, thereby blocking more perforations. At this time, more sliding rods cannot pass through the top-connected orifice plate and are pushed by the top-connected orifice plate to move toward the center of the square shell.

[0030] The basic principle of this embodiment is: when the smoke enters the inlet tube body 100 and reaches the square shell 400, the smoke flow pressure can be adjusted through the resistance balancing mechanism 500, and the pressure difference signal between the inlet tube body 100 and the outlet tube body 200 is detected by the pressure detection mechanism 700. After being processed by the controller, the graded driving mechanism 600 is driven to operate.

Of course, driven by the grading driving mechanism 600, the insertion depth and number of the sliding rods 530 can be changed, thereby arbitrarily changing the pressure of the flue gas flow.

[0035] The grading drive mechanism 600 in this embodiment includes a mounting frame 610 connected to the outside of the square shell 400, and a mounting plate 620 is connected to the mounting frame 610.
