Description

Technical Field

[0001] The present invention relates to a low-resistance and high-efficiency jet dust collector, in particular to a low-resistance and high-efficiency jet dust collector used in the field of dust removal. Background Art

[0002] A pulse jet dust collector, also known as a pulse bag dust collector, primarily consists of a bracket, hopper, middle housing, upper housing, filter bags, a jet cleaning device, and a differential pressure feedback pulse controller. During cleaning, the pulse controller continuously monitors the resistance of dust-laden gas passing through the filter bags and issues a signal to activate the jet system.

[0003] The jet dust collector uses pulsed gas to shake off the dust accumulated on the outer surface of the filter bag. Although it can remove most of the dust, the vibration generated by the expansion of the filter bag and the effect of the reverse gas make it difficult for the compacted dust to fall down, causing the filter bag to be blocked. For example, a dust collector with a high-efficiency jet cleaning device with publication number CN215995955U and a rotary switching airflow cleaning bag dust collector with publication number CN108993038B both disclose technical means to prevent dust from compacting.

[0004] However, the focus of existing dust collectors in solving the problem of ash compaction is still on how to prevent ash compaction, but there is no good solution for the compaction that has already formed. Simply relying on increasing the backflushing force to remove ash compaction is obviously difficult to achieve a good removal effect, and it is also easy to cause damage to the filter bag. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to remove the dust caked on the filter bag, thereby effectively reducing the resistance during backflushing.

[0006] In order to solve the above problems, the present invention provides a low-resistance and high-efficiency jet dust collector, comprising a pulse bag dust collector body, a mounting frame is installed in the dust collection chamber of the pulse bag dust collector body, and a plurality of filter bag assemblies distributed at equal intervals are installed on the mounting frame, the filter bag assembly comprises two upper and lower parallel bag plates, and the upper bag plate is fixedly connected to a plurality of ventilation pipes distributed around the bag plates, the filter bag is fixedly connected between the two bag plates, the lower end inner wall of the bag plate located above is fixedly connected to a hanging rod, and the hanging rod is arranged concentrically with the bag plate, the upper end inner wall of the bag plate located below is fixedly connected to a vibration seat, and the vibration seat is also arranged concentrically with the bag plate, a limiting capsule is fixedly connected between the hanging rod and the vibration seat, the lower end of the hanging rod passes through the inside of the limiting capsule, and the lower end of the hanging rod is fixedly connected to an upper electromagnetic rod, and the vibration seat is fixedly embedded with a lower electromagnetic rod on the inner wall of the upper electromagnetic rod, and the magnetic force generated by the upper and lower electromagnetic rods after energization attracts each other.

[0007] In the above-mentioned low-resistance and high-efficiency jet dust collector, the vibration effect is enhanced based on the vibration generated by the expansion of the filter bags, so as to pre-clean the dust compacted on the filter bags, thereby reducing the resistance for subsequent backblowing, effectively saving energy consumption while protecting the filter bags, and also improving the cleaning effect by enhancing the vibration of the filter bags.

[0008] As a further improvement of the present application, the limiting bag includes an outer wrapping layer, and the interior of the outer wrapping layer is fixedly inlaid with multiple inner reinforcement layers distributed at equal intervals. The outer wrapping layer is made of high-temperature resistant elastic material, and the inner reinforcement layer is made of flexible metal material.

[0009] As a further improvement of the present application, a sliding cavity is further provided on the inner wall of the vibration base, and a vibration table is slidably connected in the sliding cavity, and the height of the sliding cavity is 1-2 times the height of the vibration table.

[0010] As a further improvement of the present application, the inner walls of the upper and lower ends of the sliding cavity are fixedly connected with pads, and the pads are made of elastic material.

[0011] As another improvement of the present application, a cavity is opened on the inner wall of the vibration table, and a piezoelectric vibrator is installed in the cavity. A plurality of vibration transmission rods distributed at equal intervals are fixedly embedded on the inner wall of the vibration table, and the vibration transmission rods pass through the cavity and are fixedly connected to the piezoelectric vibrator. The end of the vibration transmission rod away from the piezoelectric vibrator is flush with the outer surface of the vibration table.

[0012] As another improved supplement of the present application, the inner wall of the filter bag is also fixedly connected to a reinforcing pad, and the side wall of the reinforcing pad is provided with a plurality of through holes distributed at equal intervals. The reinforcing pad includes an outer flexible pad and an inner reinforcing pad.

[0013] As another improvement supplement to the present application, the inner wall of the vibration adding seat facing the vibration transmission rod is also fixedly embedded with a plurality of vibration guide members 1 that fit tightly with the vibration transmission rod, and the inner wall of the bag plate below is fixedly embedded with a vibration guide member 2 that fits tightly with the vibration guide member 1, and the end of the vibration guide member 2 away from the vibration guide member 1 is fixedly connected to the reinforcing pad.

[0014] As another improvement of the present application, the vibration base and the vibration table are both made of high-strength material, and the magnetic attraction between the upper electromagnetic rod and the lower electromagnetic rod is greater than the total weight of the vibration base, the vibration table and the bag plate.

[0015] To sum up, by adding upper and lower electromagnetic rods to the existing filter bag assembly to make it extend and retract in the vertical direction, the vibration table can be vibrated up and down. In this way, when backblowing for cleaning, the vibration effect generated by the expansion of the filter bag assembly can be enhanced, and the dust compacted on the filter bag can be cleaned in advance before backblowing begins, which effectively reduces the resistance of subsequent backblowing for cleaning, effectively saves energy, and effectively prevents the filter bag from being damaged by the impact of high-pressure gas, thereby extending the service life of the filter bag assembly. Moreover, during backblowing for cleaning, the vibration of the vibration table is generated to enhance the shaking-off effect of the dust on the filter bag, and the vibration table can also transmit the vibration to the filter bag, thereby further effectively improving the cleaning effect.

DETAILED DESCRIPTION

[0026] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0027] The first implementation method:

[0028] like Figure 1 、 2 As shown in , 3 and 4, it includes a pulse bag dust collector body 1, a mounting frame is installed in the dust removal chamber of the pulse bag dust collector body 1, and a plurality of filter bag assemblies 2 distributed at equal intervals are installed on the mounting frame, the filter bag assembly 2 includes two upper and lower parallel bag plates 3, and the upper bag plate 3 is fixedly connected to a plurality of ventilation pipes 4 distributed around the bag plates 3, and a filter bag 5 is fixedly connected between the two bag plates 3, and the lower end inner wall of the bag plate 3 at the top is fixedly connected to a suspension rod 6, and the suspension rod 6 is arranged concentrically with the bag plate 3, and the upper end inner wall of the bag plate 3 at the bottom is fixedly connected to a vibration seat 7 (preferably made of polyurethane, and other materials can also be selected according to actual needs), and the vibration seat 7 is also arranged concentrically with the bag plate 3, and a limiting capsule 8 is fixedly connected between the suspension rod 6 and the vibration seat 7, and the lower end of the suspension rod 6 passes through the inside of the limiting capsule 8, and the lower end of the suspension rod 6 is fixedly connected to an upper electromagnetic rod 9 (made of electromagnetic material), and the vibration seat 7 is fixedly inlaid on the inner wall of the upper electromagnetic rod 9. The filter bag 5 is compressed and moved downwards by the action of the electromagnetic rod 9 and the lower electromagnetic rod 10.

[0029] like Figure 7 As shown, the limiting bag 8 includes an outer wrapping layer 801, and a plurality of inner reinforcement layers 802 are fixedly embedded in the interior of the outer wrapping layer 801 and are distributed around at equal intervals. The outer wrapping layer 801 is made of high-temperature resistant elastic material (polyurethane elastic material is preferably used, and other materials can also be selected according to actual needs), and the inner reinforcement layer 802 is made of flexible metal material (steel wire is preferably used, and other metal materials can also be selected according to actual needs). Since the part below the limiting bag 8 is heavy, in order to prevent the limiting bag 8 from breaking during the up and down vibration of the filter bag 5, the strength of the limiting bag 8 is strengthened by the inner reinforcement layer 802.

[0030] Compared with the existing technology, this embodiment cleans the dust caked on the filter bag 5 before backblowing begins, effectively reducing the resistance of subsequent backblowing cleaning, effectively saving energy consumption, and effectively preventing the filter bag 5 from being damaged by the impact of high-pressure gas, thereby extending the service life of the filter bag assembly 2.

[0031] The second implementation method:

[0032] This embodiment further improves the vibration of the filter bag 5 on the basis of the first embodiment, thereby effectively improving the dust cleaning effect, while the rest of the parts remain the same as the first embodiment;

[0033] like Figure 3 As shown, the inner wall of the vibration seat 7 is further provided with a sliding cavity, and a vibration table 12 is slidably connected in the sliding cavity. The height of the sliding cavity is 1-2 times the height of the vibration table 12. When the upper electromagnetic rod 9 and the lower electromagnetic rod 10 are turned on to vibrate the filter bag 5 up and down, the vibration table 12 is also driven to slide up and down in the sliding cavity, thereby enhancing the intensity of the up and down vibration of the filter bag 5, thereby effectively improving the dust cleaning effect.

[0034] like Figure 3 As shown, the inner walls of the upper and lower ends of the sliding cavity are fixedly connected with pads 13, and the pads 13 are made of elastic material (rubber is preferred, and other materials can also be selected according to actual needs). In order to prevent the vibration table 12 from hitting the sliding cavity wall and making noise when vibrating up and down, the pads 13 are used to effectively reduce noise;

[0035] like Figure 8 As shown, a cavity is provided on the inner wall of the vibration table 12, and a piezoelectric vibrator 14 is installed in the cavity (the specific model is selected according to actual needs and will not be described in detail here). A plurality of vibration transmission rods 15 (made of metal material) are fixedly embedded on the inner wall of the vibration table 12 and are distributed around the vibration table 12 at equal intervals. The vibration transmission rods 15 pass through the cavity and are fixedly connected to the piezoelectric vibrator 14. The end of the vibration transmission rod 15 away from the piezoelectric vibrator 14 is flush with the outer surface of the vibration table 12. After the back-blowing cleaning work starts, the upper electromagnetic rod 9 and the lower electromagnetic rod 10 stop working. Figure 5 As shown, at this time, the filter bag 5 is cleaned under the action of the vibration generated by the expansion and the reverse gas, but the cleaning effect is limited. Therefore, a piezoelectric vibrator 14 is installed inside the vibration table 12. The piezoelectric vibrator 14 vibrates and transmits the vibration to the vibration base 7 through the vibration transmission rod 15, so that the lower end of the filter bag 5 vibrates, thereby effectively enhancing the vibration effect of the filter bag 5 during back-blowing cleaning and accelerating the shaking off of dust.

[0036] like Figure 6As shown, the inner wall of the filter bag 5 is also fixedly connected to a reinforcing pad 11, and the side wall of the reinforcing pad 11 is provided with a plurality of through holes distributed at equal intervals. The reinforcing pad 11 includes an outer flexible pad (made of high-temperature resistant silicone material) and an inner reinforcing pad (made of metal fiber material). The reinforcing pad 11 can enhance the tensile strength of the filter bag 5 to prevent the filter bag 5 from being torn when vibrating up and down;

[0037] like Figure 3 As shown, the inner wall of the vibration adding seat 7 facing the vibration transmission rod 15 is also fixedly inlaid with a plurality of vibration guide members 16 (made of metal material) that fit closely with the vibration transmission rod 15, and the inner wall of the bag plate 3 below is fixedly inlaid with a vibration guide member 2 17 (made of metal material) that fits closely with the vibration guide member 16. The end of the vibration guide member 2 17 away from the vibration guide member 16 is fixedly connected to the reinforcing pad 11. While the piezoelectric vibrator 14 is vibrating, the vibration transmission rod 15 also transmits the vibration to the vibration guide member 16. The vibration guide member 16 then transmits the vibration to the reinforcing pad 11 through the vibration guide member 2 17. Finally, the reinforcing pad 11 transmits the vibration to the filter bag 5, thereby further enhancing the vibration effect of the filter bag 5.

[0038] In this embodiment, the vibration table 12 is vibrated to enhance the effect of shaking off the dust on the filter bag 5, and the vibration table 12 can also transmit the vibration to the filter bag 5, thereby further effectively improving the dust cleaning effect.

[0039] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
