Technical Field

[0001] The utility model relates to the technical field of funeral and interment, in particular to a dust removal and spark interception device for funeral and interment. Background Art

[0002] The dust bag is the main component used in bag dust collectors, cloth bag dust collectors, etc. It has the characteristics of high temperature resistance, high strength, acid and alkali corrosion resistance, etc. After different surface chemical treatments and post-finishing technologies, it also has the functions of easy cleaning, water and oil repellency, and anti-static. However, the dust bag is not fire-resistant. The burning of the dust bag by sparks will cause great losses to the dust removal work. Therefore, when removing smoke, it is necessary to intercept and eliminate the sparks first.

[0003] The document with prior art publication number CN216604585U provides an integrated cyclone dust removal spark interception device, which includes a cyclone dust collector fixed at the lower end of the bag dust collector, a smoke outlet fixed at the lower end of the cyclone dust collector, and an interception device arranged in the cyclone dust collector, the interception device includes an air intake shell fixed at the upper end of the smoke outlet, a filter cartridge fixed on the air intake shell, a baffle arranged obliquely fixed in the filter cartridge, a rotating rod rotatably connected in the smoke outlet, and fan blades fixed on the rotating rod. This novel integrated cyclone dust removal spark interception device can eliminate sparks in the flue gas through the interception device, so that the sparks will not contact the bag dust collector, thereby improving the dust removal efficiency of the bag dust collector, reducing the replacement of the bag dust collector, and saving enterprise costs.

[0004] However, the above device disperses the spark particles by the way that the sparks hit the baffle, so as to achieve the purpose of eliminating the sparks. However, the flow rate of smoke and dust in the pipeline is slow, and it is easy for some sparks to be difficult to extinguish after hitting the baffle or the sparks are relatively hard and difficult to be dispersed, making the elimination of sparks not thorough and safe. In view of this, we propose a dust removal and spark interception device for funeral use. Utility Model Content

[0005] In order to make up for the shortcomings of the prior art, the flow rate of smoke and dust in the pipeline is slow, which may cause some sparks to be difficult to extinguish after hitting the baffle or the sparks are relatively hard to be broken up. The utility model proposes a dust removal and spark interception device for funeral use.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the utility model is a dust removal and spark interception device for funeral use, comprising: an exhaust pipe, the discharge end of the exhaust pipe is connected to a dust removal and interception pipe, and the discharge end of the dust removal and interception pipe is connected to a cooling pipe; wherein, a blowing fan for accelerating the flow speed of smoke and dust is installed inside the exhaust pipe, a guide plate is provided on the exhaust side of the blowing fan, and a crushing roller is installed on the other side of the guide plate, and two groups of crushing rollers are symmetrically arranged about the central axis of the dust removal and interception pipe, and the outer arc surfaces of the two groups of crushing rollers are tangent to each other; the outer wall of the cooling pipe is evenly provided with multiple groups of heat dissipation fins.

[0007] Preferably, the structure of the guide plate is an inverted funnel-shaped structure, and the central axis of the guide hole of the guide plate is arranged to coincide with the central axis of the dust interception tube, and the upper port of the guide hole of the guide plate is arranged tangent to the lower edge surface of the crushing roller.

[0008] Preferably, the surfaces of the two groups of crushing rollers are provided with patterns for increasing the contact friction with the smoke particles.

[0009] Preferably, one end of one group of the crushing rollers is connected to a driving motor, and the same end of the two groups of the crushing rollers are connected by gear meshing.

[0010] Preferably, a blowing mechanism is provided on one side of the cooling tube, and the blowing mechanism includes a blowing pipe provided corresponding to the heat dissipation fins, and a second blowing fan is installed on the other end of the blowing pipe.

[0011] Preferably, a plurality of groups of blowing ducts are arranged inside the blowing pipe, and each blowing duct is correspondingly arranged in the gap between two heat dissipation fins.

[0012] The utility model is beneficial in that:

[0013] 1. The utility model can increase the speed of smoke and dust flowing in the dust interception pipe by arranging a blowing fan in the dust interception pipe, so that smoke and dust particles with sparks can hit the guide plate with greater force, which is convenient for increasing the possibility of scattering the spark particles, thereby achieving the purpose of eliminating the sparks. In addition, in order to eliminate the sparks more thoroughly and completely, the sparks with larger particle diameters that are not easily scattered can be squeezed and crushed by the crushing roller to achieve the purpose of eliminating the sparks, and the dust bag can be better protected.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 As shown, a dust removal and spark interception device for funeral use comprises: an exhaust pipe 1, a dust removal and interception pipe 2 is connected to the exhaust end of the exhaust pipe 1, and a cooling pipe 3 is connected to the exhaust end of the dust removal and interception pipe 2; wherein, a blowing fan 21 for accelerating the flow speed of smoke and dust is installed inside the exhaust pipe 1, a guide plate 22 is arranged on the exhaust side of the blowing fan 21, and a crushing roller 23 is installed on the other side of the guide plate 22, and two groups of crushing rollers 23 are symmetrically arranged about the central axis of the dust removal and interception pipe 2, and the outer arc surfaces of the two groups of crushing rollers 23 are arranged tangently; the outer wall of the cooling pipe 3 is evenly provided with multiple groups of heat dissipation fins 4;

[0023] When dust removal is performed on smoke generated in funerals, it is first necessary to intercept and eliminate sparks carried in the smoke. During the elimination, the generated smoke is discharged into the dust interception pipe 2 through the exhaust pipe 1, and is accelerated by the blowing fan 21 in the dust interception pipe 2 to hit the guide plate 22 more quickly. After hitting the guide plate 22, the sparks are broken and scattered, and then the smoke and the broken sparks are introduced into between the two crushing rollers 23 through the guide holes of the guide plate 22, and the spark particles are crushed again by the rotation of the two crushing rollers 23, so as to achieve the purpose of more thorough removal of sparks, and then the smoke flows into the cooling pipe 3 through the dust interception pipe 2 for cooling treatment, and finally is discharged into the dust bag for dust removal treatment;

[0024] By setting a blowing fan 21 in the dust interception tube 2, the speed of smoke flowing in the dust interception tube 2 can be increased, so that the smoke particles carrying sparks have greater force when hitting the guide plate 22, which is convenient for increasing the possibility of scattering the spark particles, thereby achieving the purpose of eliminating the sparks. In order to eliminate the sparks more thoroughly and completely, the sparks with larger diameters that are not easily scattered can be squeezed and crushed by the crushing roller 23 to achieve the purpose of eliminating the sparks, and the dust bag can be better protected.

[0025] The structure of the guide plate 22 is an inverted funnel-shaped structure, and the central axis of the guide hole of the guide plate 22 is arranged to coincide with the central axis of the dust interception pipe 2, and the upper port of the guide hole of the guide plate 22 is arranged tangent to the lower edge surface of the crushing roller 23;

[0026] The guide plate 22 serves as a baffle for impact on one hand, and can also guide smoke and broken sparks into between the two crushing rollers 23 on the other hand. After being squeezed by the crushing rollers 23 once, the sparks are eliminated.

[0027] The surfaces of the two groups of crushing rollers 23 are provided with patterns for increasing the contact friction with the smoke particles;

[0028] Arranging patterns on the crushing roller 23 can increase the friction between the crushing roller and the smoke particles, avoiding slipping and the inability to squeeze and crush the smoke particles. The pattern can be arranged in the form of horizontal stripes or vertical stripes, etc. In order to better squeeze and crush the dust particles, the horizontal stripes parallel to the rotating axis of the crushing roller 23 are the best.

[0029] One end of a set of crushing rollers 23 is connected to a driving motor 24, and the same end of the two sets of crushing rollers 23 is meshed and connected via a gear 25;

[0030] One of the crushing rollers 23 is driven to rotate by the driving motor 24, and the other crushing roller 23 is driven to rotate by the meshing of the two gears 25 on the crushing roller 23. The rotation direction of the crushing roller 23 is Figure 2 Only by adjusting the rotation direction can the smoke and dust particles be better crushed.

[0031] A blower mechanism 5 is provided on one side of the cooling tube 3, and the blower mechanism 5 includes a blower tube 51 provided corresponding to the heat dissipation fins 4, and a blower fan 53 is installed at the other end of the blower tube 51; a plurality of blower channels 52 are provided inside the blower tube 51, and each blower channel 52 is provided in the gap between two heat dissipation fins 4;

[0032] The smoke passing through the dust removal interception tube 2 can remove and eliminate the sparks it carries, but the smoke flowing inside still has a relatively high temperature. In order to avoid that there are still relatively small sparks that have not been removed, the sparks can be extinguished by cooling, thereby once again achieving the purpose of removing the sparks;

[0033] The flue gas passing through the cooling tube 3 will diffuse its temperature outwards, and the contact area with the external environment can be increased through the heat dissipation fins 4, thereby increasing the heat dissipation intensity. The provision of the blower mechanism 5 can increase the flow rate of the air around the heat dissipation fins 4, thereby increasing the heat dissipation capacity. The outside air is sucked in by the blower fan 53 and then blown toward the heat dissipation fins 4 through the blower pipe 51 for heat dissipation. A plurality of blower ducts 52 are provided in the blower pipe 51 and are aligned between every two heat dissipation fins 4, so that air can flow between every two heat dissipation fins 4, thereby ensuring that the heat dissipation effect of each heat dissipation fin 4 is very good.

[0034] Working principle: When removing dust from smoke generated during funerals, it is first necessary to intercept and eliminate sparks carried in the smoke. During the elimination, the generated smoke is discharged into the dust interception pipe 2 through the exhaust pipe 1. In the dust interception pipe 2, it is accelerated by the blowing fan 21 and hits the guide plate 22 more quickly. After hitting the guide plate 22, the sparks are broken and scattered. Then, the smoke and the broken sparks are introduced into between the two crushing rollers 23 through the guide holes of the guide plate 22. The spark particles are crushed again by the rotation of the two crushing rollers 23 to achieve the purpose of more thorough removal of sparks. Then, the smoke flows into the cooling pipe 3 through the dust interception pipe 2 for cooling treatment, and finally is discharged into the dust removal bag for dust removal treatment.
