Description

TECHNICAL FIELD

[0001] The present application relates to a dust filtering device, in particular to a dust filter bag mounting device and a dust filter. BACKGROUND

[0002] The bag filter and the electric-bag combined dust filter are both dry dust filtering devices. The bag filter, also known as a filter dust collector, is a dust collecting device that uses a bag filter element made of fiber fabric to capture solid particles in dust-containing gas. Its working principle is that dust particles are intercepted by colliding with fibers due to inertial force when passing through the filter fabric fibers. The electric-bag combined dust filter, as a new type of combined dust filter, combines the characteristics of electrostatic precipitation and bag dust collection, and is a high-efficiency dust collector that collects dust through the pre-collection of the front-stage electric field, the charging effect, and the filtration of the rear-stage filter bag area. The electric-bag combined dust filter uses the shell and dust storage system of the original electric dust collector, retains the front-stage electric field of the electric dust collector, and removes the rear-stage electric field, and installs a bag dust collector in the removed rear-stage electric field. By organically combining the two types of dust collectors, the dust removal advantages of the electric dust collector and the bag dust collector are fully utilized, and new performance advantages are generated by their combination, which makes up for the dust removal shortcomings of the electric dust collector and the bag dust collector.

[0003] The bag area of the electric-bag combined dust filter or the bag dust collector relies on filter bags for filtration and dust removal, and uses pulse dust removal for dust removal. The filter bags commonly used in engineering are long cylindrical filter bags, with a maximum length of 8 meters. The installation of filter bags is carried out by manual carrying and then entering through the clean gas chamber manhole door, and then manually installing one by one on site. The height of the clean gas chamber is generally less than 3 meters, so on-site installation is required to be divided into sections, and flanges are used for connection, so that locking bolts and other steps need to be performed. The operation of installation and disassembly is complex, very inconvenient, and is prone to problems such as damage to the filter bag by human error, poor installation precision, and the like.

The dust collector filter bag installation device 10 of the embodiment is detachable, and the whole dust collector filter bag installation device 10 is detached through the detachable connection of the limiting member 6 and the first guide rail 26.

[0067] The dust collector 20 of the embodiment can realize automatic installation of integrated filter bags or segmented filter bags. When integrated filter bags are installed, the specific installation method is as follows: referring to Figure 1, first, the dust filter bag installation device 10 is placed on the first guide rail 26, and the dust filter bag installation device 10 is firmly clamped on the first guide rail 26 by the limiting piece 6. Then, the control system 30 is controlled, the dust filter bag installation device 10 is moved to the filter bag pile by the first sliding piece 4, the filter bag 24 is grabbed by closing the grabbing face 11, and the fastener 12 is closed to tighten and lock. The grabbed filter bag 24 is moved to the flower plate hole in the horizontal direction of the flower plate 23 (if the vertical space allows, it is directly adjusted to the vertical flower plate direction), and the rotating force is provided by the rotating piece 2 (such as Figure 2 the arrow D direction in the middle), so that the filter bag 24 is vertically aligned with the flower plate hole, and the lifting piece 3 is adjusted to lower the height of the filter bag 24 until it is installed in the flower plate hole.

[0068] When installing the segmented filter bag, taking two-section filter bag installation as an example, the filter bag 24 is divided into a first filter bag section 241 (the link uses external threads) and a second filter bag section 242 (the link uses internal threads, and a small through hole is provided at the bottom of the second filter bag section 242, which is matched with the air nozzle 255). The specific installation method is as follows: see Figure 5 、 7 -10, first, the control system 30 is controlled to move the second sliding piece 252 along the groove surface of the second guide rail 27 (such as Figure 7 ), so that the dust removal device 25 as a whole rises upward along the vertical direction to the top of the second guide rail 27, the second sliding piece 252 (universal wheel in this embodiment) is turned to the horizontal direction, the universal wheel is clamped with the track of the second guide rail 27, and the base body is fixed (such as Figure 8 ), then the second filter bag section 242 is installed through the flower plate hole by the dust filter bag installation device 10, and the bottom of the filter bag 24 is ensured to enter the containing groove 253 for fixation, and the above steps are repeated to accurately install the second filter bag section 242 of all filter bags 24 into the containing groove 253 for fixation, then the universal wheel is turned to the vertical direction and moved along the groove surface (such as Figure 9 ), so that the base body 251 moves back to the bottom end of the second guide rail and is fixed by the stop piece 28 (such as Figure 10 ). Then, the first filter bag section 241 of each filter bag is installed through the flower plate hole one by one according to the method of installing an integrated filter bag, a pressing device is installed at the top of the filter bag 24, and finally the vertical position of the stop piece 28 is adjusted to make the threads of the first filter bag section 241 and the second filter bag section 242 correspond to each other, the rotating piece 254 is started to provide rotating power, and the base body 251 is gradually adjusted upward to fine-tune the two-section filter bag of each filter bag to be screwed, realizing intelligent installation of the two-section filter bag (such as Figure 5 ].

[0069] In this embodiment, by designing the above-mentioned dust collector filter bag mounting device 10 and ash removal device 25, cooperating with the control system 30, on the one hand, the automatic installation of the filter bag 24 is realized, which can not be limited by the height of the clean gas chamber 21, realizing the automatic installation of integrated filter bags, and also realizing the automatic installation of segmented filter bags, which solves the problems of difficulty, slowness and low precision of manual installation of filter bags in the existing electric-bag composite dust collector and bag-type dust collector, greatly improving the equipment performance, installation quality and speed. The ash removal device 25 can completely avoid the occurrence of filter bag bottom wear, and at the same time, the ash removal is optimized, the threaded connection of segmented filter bags is simplified, and the butt joint workload of long filter bag segmented installation is greatly simplified.

[0070] The advantages of the embodiment are as follows:

[0071] 1. The dust collector filter bag mounting device 10 can realize the automatic installation of integrated and segmented filter bags, which can improve the quality, precision and air tightness of filter bag installation compared with manual installation, shorten the installation period, and greatly improve the performance of the dust collector.

[0072] 2. The dust collector filter bag mounting device 10 is detachable, which ensures that a set of equipment can be applied to multiple dust collectors in turn, and only needs to be clamped and installed to the first guide rail during use and connected to the power supply to be used, which is convenient and economical.

[0073] 3. The ash removal device 25 can completely avoid the occurrence of filter bag bottom wear, and bidirectional ash removal can improve the dust removal efficiency.

[0074] 4. The multi-segment filter bag adopts threaded connection instead of the current flange connection, which greatly simplifies the filter bag butt joint installation workload.

[0075] This specific embodiment is only an explanation of the application, and is not a limitation of the application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the application, it is protected by the patent law.
