Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and preferably relates to a dust collector body with enhanced sealing. Background Art

[0002] The dust collector body is used for secondary and tertiary dust removal equipment in the metallurgical and mining industries. When the dust collector body separates the dust in the flue gas, a cover is required to prevent dust leakage during the separation process. Poor sealing of the cover will cause employees to inhale dust, which will affect their health and reduce the efficiency of the dust collector body in purifying the flue gas, which will affect the service life of the dust collector body for a long time.

[0003] At present, felt seals and "R" type rubber seals are commonly used to seal the dust collector body. However, felt seals are airtight and there is no mutual fixation between the felt and the cover plate, so the felt often falls off or deviates, resulting in poor sealing of the dust collector body cover plate. The sealing effect of "R" type rubber seals is better than that of felt, but the cover plate is currently fixed by tightening it with bolt pressure plates around the top of the cover plate. Due to the deformation of the cover plate and the loosening of the cover plate bolts, poor sealing often occurs. Especially in the rainy season, it is very easy to cause dust caking due to the inhalation of rainwater, which makes the dust collector body unable to release dust and the equipment cannot operate normally. At the same time, when checking the inside of the dust collector, the fixing bolts need to be unscrewed one by one, so the inspection efficiency is relatively low. In addition, the sealing contact surfaces of these two sealing forms are parallel contacts. This sealing structure has no slope compensation, poor sealing and is greatly affected by the installation quality.

[0004] For example, the invention patent application with application publication number CN117138490A discloses a pulse bag dust removal device, which includes a dust collector main body, a ash hopper, a pulse blowing mechanism, a filtering mechanism, a hatch, a locking mechanism, a supporting mechanism and a sealing mechanism. The filtering mechanism includes a connecting plate 1, a connecting plate 2 and a filter bag. One end of the filter bag is detachably connected to the connecting plate 1, and the other end of the filter bag is detachably connected to the connecting plate 2. An operating port is provided on the side wall of the dust collector main body, and the hatch is hinged above the operating port. The sealing mechanism is arranged at the operating port. The filter bag can be removed from the connecting plate 1 and the connecting plate 2. An inflation groove is provided at the operating port. The sealing mechanism includes an electromagnetic valve 1, an air pipe, and an elastic sealing ring. The electromagnetic valve 1 is connected to the elastic sealing ring through the air pipe through the inflation port. The elastic sealing ring is hollow. The electromagnetic valve 1 controls the inflation and deflation of the elastic sealing ring. The technical solution adopted in this patent application is to use an electromagnetic valve to control the inflation into a hollow sealing ring, so that the sealing ring expands and blocks the hatch to ensure the airtightness of the entire dust collector body. However, this technical solution has a complex structure, high cost and low feasibility. In addition, frequent inflation and deflation will extremely reduce the service life of the sealing ring, thereby affecting the sealing of the entire dust collector body. Utility Model Content

[0008] Preferably, the inside of the sealing ring has an annular channel coaxially arranged with the central axis of the sealing ring so that the harder rubber texture is easier to deform under the action of the cover's own gravity and the negative pressure in the dust collector, thereby better fitting the cover.

[0009] Preferably, the shape of the annular channel is the same as that of the sealing ring, so that the sealing ring is more evenly stressed and fits the cover better.

[0010] Preferably, the short tube is vertically arranged on the upper surface of the dust collector body, and the inner diameter of the short tube is larger than the diameter of the opening, so as to facilitate fixing the sealing ring on the inner wall of the short tube and the upper surface of the dust collector body at the same time, thereby preventing the sealing ring from falling off or deviating when subjected to force.

[0028] By arranging a sealing ring 5 with an inclined contact surface with the sealing cover 3 on the top of the dust collector body 1, and then cooperating with the sealing cover 3 with a lower surface inclined toward its central axis, the sealing surface is made to be an inclined surface with compensation, thereby optimizing the structural form of the sealing part and improving the sealing effect; and under this inclined sealing structure, the sealing cover 3 can be firmly fixed at the opening 4 of the dust collector body 1 under the dual effects of its own gravity and the negative pressure of the dust removal system, without the need to use additional bolts and pressure plates, thereby avoiding poor sealing due to deformation of the cover plate, loosening of the cover plate bolts, etc., and greatly improving the working efficiency of the dust collector when checking the bags.

[0029] Specifically, the sealing ring 5 is made of rubber. The sealing ring 5 made of rubber has good sealing performance. The elasticity of rubber can overcome a small amount of poor sealing problems caused by uneven joint surfaces.

[0030] Specifically, the inside of the sealing ring 5 is provided with an annular channel 6 coaxially arranged with the central axis of the sealing ring 5 so that the harder rubber texture is more easily deformed under the action of the gravity of the cover 3 itself and the negative pressure in the dust collector, thereby better fitting the cover 3.

[0031] Specifically, the shape of the annular channel 6 is the same as that of the sealing ring 5 , so that the sealing ring 5 is more evenly stressed and fits the cover 3 better.

[0032] Specifically, the short tube 2 is vertically arranged on the upper surface of the dust collector body 1, and the inner diameter of the short tube 2 is larger than the diameter of the opening 4, so as to facilitate fixing the sealing ring 5 on the inner wall of the short tube 2 and the upper surface of the dust collector body 1 at the same time, thereby preventing the sealing ring 5 from falling off or deviating when subjected to force.

[0033] Specifically, the sealing ring 5 is arranged on the inner side of the short tube 2 and fixed to the upper surface of the dust collector body 1. The cross-section of the sealing ring 5 is a right-angled trapezoid. The side of the sealing ring 5 close to the dust collector body 1 is perpendicular to the side of the sealing ring 5 close to the short tube 2, and the side of the sealing ring 5 close to the dust collector body 1 is the long bottom side of the sealing ring 5. The sealing ring 5 with a right-angled trapezoidal cross-section can better fit the short tube 2, the upper surface of the dust collector and the cover 3 at the same time.

[0034] Specifically, the lower surface of the cover 3 is provided with an annular sealing plate 7 coaxial with the cover 3 , and the outer surface of the annular sealing plate 7 is the front cover.

[0037] Specifically, a handle 10 is provided on the upper surface of the cover 3 to facilitate assembly and disassembly of the cover 3 .

[0038] Working principle: Use the handle to place the cover on the short tube so that the sealing layer on the outer surface of the annular cover fits with the inclined surface of the sealing ring. At this time, start the dust collector and the dust collector body is in a negative pressure state. The cover is firmly fixed on the short tube under the action of its own gravity and the negative pressure in the dust collector body. At this time, the baffle arranged on the outer periphery of the cover can prevent rainwater and other foreign objects from eroding the sealing ring and the sealing layer. When the inside of the dust collector needs to be inspected, it is only necessary to shut down the dust collector. At this time, the negative pressure in the dust collector disappears, and the maintenance personnel only need to overcome the weight of the cover by the handle to quickly remove the cover to inspect the inside of the dust collector. After the inspection, it is only necessary to place the cover on the short tube by the handle and start the dust collector to achieve the sealing of the dust collector.
