Description

Technical Field

[0001] This utility model relates to the field of bag maintenance technology, and in particular to a leak detection device for dust collector bags. Background Technology

[0002] Tubular pulse-jet baghouse dust collectors are dry dust collection devices widely used in industries such as metallurgy, power, cement, and chemicals. The filter bags are typically made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the dust collector, large dust particles settle due to gravity and fall into the ash hopper, while fine dust particles are trapped by the filter media, thus achieving gas purification. As the core component of the dust collector, the filter bags are usually vertically suspended inside the dust collector in the form of cylindrical bags. However, in actual production, leaks in individual filter bags can lead to an increase in the dust concentration emitted from the dust collection chimney, failing to meet environmental protection requirements. Furthermore, leaks reduce the operating efficiency of the dust collector, increase fan wear, and allow dust to enter the dust collection chamber through the damaged bags, contaminating and clogging other bags, thereby shortening the service life of the filter bags and increasing maintenance difficulty. Therefore, timely detection and location of leaking filter bags are crucial to ensuring the efficient operation of the dust collector.

[0003] Currently, the main methods for detecting leaks in dust collector bags are as follows: 1. Visual inspection: Open the top cover of the dust collector housing and observe the dust accumulation on the perforated plate surface to determine the leaking compartment and approximate area. Then, each bag is pulled out for inspection. However, due to the influence of airflow inside the dust collector, leaked dust may not accumulate near the leak point, resulting in low detection efficiency and requiring a large amount of manpower. 2. Fluorescent powder detection: Sprinkle fluorescent powder into the airflow at the dust collector inlet and then illuminate it with a special monochromatic lamp to locate the leaking bag. However, this method requires a large amount of fluorescent powder, resulting in high costs, and the fluorescent substance is harmful to the human body, posing a safety hazard. A novel online leak detection device for filter bags, with announcement number CN202322545839.0, allows a lamp holder to be suspended inside the filter bag via a power cord. Under the illumination of the lamp beads, a camera captures the internal condition of the filter bag, and finally transmits the images captured by the camera to a terminal device via a wireless communication module. Operators can then observe the specific condition of the filter bag through the terminal device. However, since the top of the dust collector housing is often equipped with a sweeping pipe, it affects the centered placement of the device. Placing the device against one side of the filter bag will affect the image captured by the camera and affect the resolution. In addition, the design is inconvenient for cable retraction and deployment, and the operation is relatively cumbersome. Summary of the Invention

[0004] The purpose of this invention is to provide a dust collector bag leak detection device to address the above-mentioned problems, thereby solving the technical problems of traditional dust collector bag leak detection devices being inconvenient to place in the center and inconvenient to operate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dust collector bag leak detection device, comprising a probe, several lighting lamps, a camera, a centering cone, a cable winding and unwinding device, and a display; the lighting lamps are mounted on the probe and used for illuminating the inside of the bag, the camera is mounted on the probe and used for photographing the inside of the bag, and the camera is connected to the display; the centering cone is inverted cone-shaped, and a through hole is provided at the lower part of the centering cone; a hanging rope is provided on the cable winding and unwinding device, which can wind and unwind the hanging rope, and the end of the hanging rope is connected to the upper part of the probe, and the probe can pass through the through hole.

[0006] Furthermore, the cable winding and unwinding device includes a frame, a coiling reel, and a reversing pulley; the frame is mounted on the centering cone, the coiling reel is mounted on the frame, one end of the lifting rope is coiled on the coiling reel, the reversing pulley is mounted on the frame, and the lifting rope is movably wound around the reversing pulley.

[0007] Furthermore, the reversing pulley includes a first reversing pulley, a second reversing pulley, a third reversing pulley, and a fourth reversing pulley. The first reversing pulley is located in the middle of the opening on the centering cone plate, the second reversing pulley is located at the edge of the opening on the centering cone plate, and the third and fourth reversing pulleys are both located on the upper part of the frame. The suspension rope passes sequentially through the coiled pulley, the fourth reversing pulley, the third reversing pulley, the second reversing pulley, the first reversing pulley, and the through hole, and is connected to the probe.

[0008] Furthermore, the frame includes horizontal and vertical bars forming an L-shaped structure, the first reversing pulley is installed at the end of the horizontal bar, the second reversing pulley is installed at the connection between the horizontal and vertical bars, the third and fourth reversing pulleys are installed on both sides of the upper part of the vertical bar; the coiled wheel is rotatably installed on one side of the vertical bar.

[0009] Furthermore, a hand crank is provided on the side of the reel.

[0010] Furthermore, the lower part of the probe is inverted cone-shaped, and several of the lighting lamps are evenly distributed and installed on the lower cone surface of the probe.

[0011] Furthermore, the camera is connected to the display via a wired or wireless means.

[0012] Furthermore, the lighting is powered by an external power cord or battery.

[0013] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0014] 1. In use, the operator only needs to open the dust collector housing cover, place the centering cone disc into the circular opening corresponding to the cylindrical filter bag, and insert the probe into the filter bag through the through hole of the centering cone disc. The probe is then smoothly placed into the filter bag using a suspension rope. With the aid of a lighting lamp, the camera can clearly capture the internal condition of the filter bag and transmit the image in real time to the display. Simultaneously, the L-shaped cable winding and unwinding device avoids the sweeping pipe located above the filter bag opening. By winding or unwinding the suspension rope through the cable winding and unwinding device, the probe can move up and down along the central axis of the filter bag, achieving detection of the entire filter bag. Based on the above, the operator can quickly locate damaged filter bags, significantly reducing the time and labor intensity of manual inspection, greatly improving detection efficiency, ensuring timely repair of the dust collector, and maintaining efficient operation. This solves the technical problems of traditional dust collector filter bag leak detection devices, which are inconvenient to center and operate. Attached Figure Description
