Detailed Description

Example 1

Referring to fig. 1 to 3, an explosion-proof industrial dust collector comprises a frame 1, wherein a housing 2 is arranged on the frame 1, a dust-removing chamber is arranged in the housing 2, a dust-containing air inlet 21 is arranged on the side surface of the top of the housing 2, the dust-containing air inlet 21 is connected to an air inlet pipe 22, a clean air chamber 31 is arranged on the side surface of the housing 2, a clean air outlet 32 is arranged at the bottom of the clean air chamber 31, a filter cartridge assembly 6 is arranged at the dust-removing chamber, an ash hopper 41 is arranged at the bottom of the dust-removing chamber, and an ash discharge valve 42 is arranged at the bottom of the ash hopper 41. The above can be referred to the prior art and will not be described in detail.

The ash bucket is a 65-degree ash bucket 41 (the ash bucket is a 65-degree ash bucket, namely the ash bucket is conical, the included angle between the conical surface and the horizontal plane is 65 degrees, and the ash can be conveniently discharged by the design with reference to the prior art); a spray head 33 for ash removal (used for cleaning ash of a filter cartridge component) is arranged at the position of the clean air chamber 31, the spray head 33 for ash removal is connected to a compressed air source through an air pipe, and a diaphragm valve is arranged at the position of the spray head 33 for ash removal; set up entry flame proof valve 23 on the air-supply line 22 (the flame proof valve can refer to prior art, and the main function is when the dust remover takes place the explosion, and the flame proof valve can be with explosion pressure separation, avoids inside explosion pressure shock wave gets into the workshop through the pipeline, arouses secondary safety accident), set up explosion-proof safety subassembly on the casing 2.

In the embodiment, an ash bucket 43 is arranged below the ash bucket 41. The ash bucket with the movable wheels is convenient for workers to clean.

In an embodiment, the explosion-proof safety assembly comprises a top rupture disc 51 and a gas explosion suppression device 52; the top explosion venting sheet 51 is arranged at the top of the shell 2 (the top of the dust removal chamber); the gas explosion suppression device 52 is provided on the side of the housing 2 (dust removal chamber side). Reference is made to the prior art for gas explosion suppression devices, including but not limited to the following: the explosion suppression device comprises a pressure sensor arranged in a shell, a control unit arranged on the shell and an explosion suppression gas injection component arranged at the shell, wherein the pressure sensor and the explosion suppression gas injection component are connected with the control unit.

When the interior of the dust remover explodes, the pressure is larger than or equal to the opening value of the explosion venting sheet, the opening pressure value of the explosion venting sheet is designed to be smaller than the pressure resistance value of the dust remover body, so that when the pressure reaches, the explosion venting sheet automatically vents and protects the dust remover. When the pressure sensor detects explosion in the dust remover instantly and the pressure rises instantly, explosion suppression gas is injected instantly to suppress the explosion.

In an embodiment, the filter cartridge assembly comprises a plurality of filter cartridges, each filter cartridge being arranged in an inclined arrangement.

The dust-containing air enters the dust remover from the air inlet pipe and the dust-containing air inlet, is filtered by the filter cartridge assembly, the dust is intercepted on the surface of the filter material, and the filtered clean air enters the clean air chamber and is discharged from the clean air outlet.

The equipment adopts the mode air inlet of down-flow formula, and upper portion is dirty waste gas direction of admitting air, and the dust filters back clean air back lateral part air-out, avoids traditional dust remover lower air admission mode of giving vent to anger on, and it is unreasonable to lead to the dust cake whereabouts.

The embodiment can be further modified, namely: the air inlet pipe and the interior of the shell can adopt an ETFE (ethylene-tetrafluoroethylene) coating or a PTFE (polytetrafluoroethylene) coating, so that the protection effect is improved. The whole floor area of the equipment is small, the resistance of the equipment is small, and the space and the energy consumption are effectively saved. The dust remover shell and the like can be processed and manufactured by adopting Q235B or A3 plates; the wall thickness is 4.0 mm; the machine body is designed to be reinforced and has strong pressure resistance.

Example 2

The basic scheme is the same as that of embodiment 1, except that, referring to fig. 4, a convex edge 43a (arranged in the circumferential direction) is arranged on the top of the ash barrel 43 in the circumferential direction, an external thread is arranged on the upper part of the outer side of the ash barrel 43, an inner ring 43b with an internal thread is arranged at the external thread, an outer ring 43c is arranged on the outer side of the inner ring 43b, and the inner ring 43b and the outer ring 43c are connected through a bracket, wherein a threaded hole is arranged on the outer side of the ash barrel 43 and at the bottom of the external thread, and a limit screw 43d is arranged at the threaded hole.

The outer ring is used as a handrail, so that the ash bucket is convenient to use, and can be protected to a certain extent during impact. The lifting can be realized after the outer ring is rotated, so that the height of the outer ring can be adjusted, and the use is facilitated. The convex edge and the limiting screw can prevent the inner ring from being separated. The convex edge can also play a certain protection role in the threaded connection part of the inner ring, so that falling foreign matters are prevented from entering the connection part.

For the sake of brevity, the description of the prior art is omitted herein.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, and all technical solutions belonging to the principle of the present invention belong to the protection scope of the present invention. Modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
