Description

Technical Field

[0001] This utility model belongs to the field of dust collector bag testing technology, specifically relating to a dust collector bag testing device. Background Technology

[0002] Baghouse dust collection is one of the common methods for flue gas dust removal. Dust-laden flue gas flows through the filter bags, and the windward side of the bags can block a large amount of dust. The cleaned flue gas can then flow out through the filter bags. Testing the air permeability of the filter bags is essential, as it helps us evaluate the effectiveness of the filter bags and ensures efficient and stable operation of the equipment after installation. Patent number 202021199751.8 discloses a filter bag installation and testing device, including a body. A telescopic rod is fixedly connected to the bottom of the body, and a caster wheel is fixedly connected to the bottom of the telescopic rod. A spring is movably sleeved on the outer surface of the telescopic rod. A handle is fixedly installed on the left side of the body, and a fixing block, a filter bag tube, and a controller are fixedly installed on the top of the body from left to right. However, when pumping dust into the filter bag, the lack of internal support makes it prone to folding, affecting the full entry of dust into the filter bag and thus the test results. Utility Model Content

[0003] The purpose of this invention is to provide a dust collector bag detection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A dust collector bag testing device, comprising:

[0006] The testing chamber is connected by a support member. A cover plate is installed at the top of the testing chamber to seal the chamber and facilitate testing. An internal testing mechanism is installed within the testing chamber. This mechanism includes a dust pipe, a support member, a mounting member, and a dust detector. One end of the dust pipe has the support member to open the interior of the dust collector bag, allowing dust to be introduced into the pipe. The mounting member is also installed on the dust pipe to fix and seal the opening of the dust collector bag, facilitating testing. The other end of the dust pipe passes through the cover plate and connects to an external dust inlet device to inject dust-laden air, facilitating the testing of the dust collector bag's filtration efficiency. The dust detector is installed at the bottom of the testing chamber to detect dust inside the chamber, thereby determining the dust collector bag's filtration efficiency. The testing chamber also has a segmented fixing mechanism to fix the dust collector bag in sections, facilitating testing of the filtration efficiency at multiple locations.

[0007] Preferably, the expanding member includes a mounting plate, a movable plate, a two-bar linkage, and a driving component. The mounting plate is fixedly installed on the outer side of one end of the dust pipe, and the movable plate is slidably connected to the outer side of the dust pipe. The movable plate is sleeved on the outer side of the dust pipe. The two-bar linkage is hinged between the mounting plate and the movable plate. The two-bar linkage consists of two hinged straight rods. The output end of the driving component is connected to the movable plate. After the expanding member is placed inside the dust collector bag, the driving component drives the movable plate to slide on the outer side of the dust pipe and approach the mounting plate, thereby driving the two-bar linkage to rotate. This reduces the angle between the two sets of straight rods of the two-bar linkage, thus expanding the dust collector bag and facilitating dust filling for dust filtration and detection.

[0008] Preferably, the driving component includes a fixed clamping plate and an electric push rod. The fixed clamping plate is installed at the outer end of the dust pipe, and the electric push rod is installed on one side of the fixed clamping plate. The electric push rod is configured in two sets, and the output end of the electric push rod is connected to one side of the moving plate. The moving plate is moved by the output end of the electric push rod, thereby realizing the rotation of the two-bar strut and opening or closing.

[0009] Preferably, the mounting component includes a movable clamp and a threaded sleeve. The movable clamp is slidably connected to the outside of the dust pipe, and the threaded sleeve is connected to one side of the movable clamp. The threaded sleeve is threadedly connected to the dust pipe and is fitted onto its outside. During installation, the port of the dust collector bag is first fitted onto the fixed clamp, and then the threaded sleeve is rotated. The threaded sleeve engages with the dust pipe and drives the movable clamp to move on the dust pipe until the movable clamp engages with the fixed clamp and clamps and fixes the port of the dust collector bag, thereby sealing the port and facilitating the filtration testing of the dust collector bag.

[0010] Preferably, a purification chamber is installed at the bottom of the detection chamber, and the purification chamber is connected to the detection chamber, so that dust can enter the interior of the purification chamber, be purified and then discharged, which is beneficial to environmental protection. Furthermore, a filter screen can be installed inside the purification chamber to filter the dust and prevent the dust from entering the external environment and causing air pollution.

[0011] Preferably, the segmented fixing mechanism includes an upper clamping plate, a lower clamping plate, a driver, a connecting ear plate, and a bidirectional screw. The upper clamping plate and the lower clamping plate are respectively provided at the upper and lower ends of the inside of the detection box. The connecting ear plate is connected to one side of the inner wall of the detection box, and the bidirectional screw is rotatably connected to one side of the connecting ear plate. The bidirectional screw is threadedly connected to the upper clamping plate and the lower clamping plate respectively. The driver is installed at the bottom of the inside of the detection box. The driver is configured as a forward and reverse motor. The output end of the driver is connected to the bidirectional screw. When it is necessary to perform filtration detection on the upper half of the dust collector bag, one end of the dust collector bag and the middle part of the dust collector bag are placed between the two sets of upper and lower clamping plates. The driver drives the bidirectional screw to rotate forward, so that the upper and lower clamping plates are threadedly engaged with the bidirectional screw respectively, thereby driving the upper and lower clamping plates to move closer to each other and clamp and fix the middle part of the dust collector bag to achieve a seal. Then, the detection mechanism is used to perform filtration detection on the upper half of the dust collector bag, realizing the detection of each part.

[0012] Preferably, the segmented fixing mechanism further includes a second connecting ear plate and a limiting guide rod. The second connecting ear plate is connected to the other side of the inner wall of the detection box, and the limiting guide rod is connected to one side of the second connecting ear plate. The upper clamping plate and the lower clamping plate have through holes that cooperate with the limiting guide rod, which facilitates the sliding cooperation between the limiting guide rod and the limiting guide rod, enabling the upper clamping plate and the lower clamping plate to move vertically. Furthermore, the upper clamping plate and the lower clamping plate are provided with sealing gaskets on the sides that are close to each other, which helps to improve the clamping and sealing effect.

[0013] Preferably, the support includes a support column and a support base plate. The support column is connected to both sides of the detection box through a fixed lug plate. The lower ends of the two sets of support columns are connected to the upper ends of the support base plate, which serves to support the detection box.

The two-bar strut 23 is hinged between the mounting plate 21 and the movable plate 22. The two-bar strut 23 is set as two hinged straight rods. The output end of the driving component is connected to the movable plate 22. After the expansion component is placed inside the dust collector bag, the driving component drives the movable plate 22 to slide on the outer side of the dust pipe 20 and approach the mounting plate 21, thereby driving the two-bar strut 23 to rotate. This reduces the angle between the two sets of straight rods of the two-bar strut 23, thus expanding the dust collector bag.
