Description

Technical Field

[0001] This utility model belongs to the field of separation device technology, specifically relating to a dust and solid particle separation device. Background Technology

[0002] In chemical reaction systems, the waste gas generated by chemical reactions contains not only dust but also large solid particles. When treating the waste gas, it is necessary to filter out the solid particles and dust in the waste gas in order to meet the emission standards.

[0003] The commonly used filtration methods are spraying and screen filtration. Because dust and solid particles have a large difference in size, when using spraying, solid particles tend to settle in the sewage pipe, causing blockage. If screen filtration is used, the large amount of dust in the exhaust gas can easily cause the screen to clog, reducing its lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a dust and solid particle separation device that can not only prevent solid particles from clogging the dust discharge pipe, but also prevent dust from clogging the large-pore filter component and affecting its service life, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust and solid particle separation device, comprising a shell and a partition, wherein the partition is provided inside the shell, dividing the interior of the shell into a first separation chamber and a second separation chamber, and the top of the partition is provided with a vent hole for connecting the first separation chamber and the second separation chamber, wherein a large-pore filter assembly is provided inside the first separation chamber, and a drive assembly for pulling the large-pore filter assembly is provided in the middle of the first separation chamber, the drive assembly passing through the middle of the large-pore filter assembly, and a spray assembly is provided at the top of the inner side of the second separation chamber.

[0006] Furthermore, an air inlet pipe and an air outlet pipe are fixedly connected to the two ends of the top of the outer shell, respectively. The bottom ends of the first separation chamber and the second separation chamber are both cone-shaped. The bottom ends of the first separation chamber and the second separation chamber are fixedly connected to a particle discharge pipe and a dust discharge pipe, respectively. Valves are provided at the top of the particle discharge pipe and the top of the dust discharge pipe. A cover plate is fixedly connected to the top of the outer shell.

[0007] Furthermore, the large-pore filter assembly has two layers. The large-pore filter assembly includes a U-shaped frame fixedly connected to the inside of the first separation chamber. A sliding groove is provided on the inner side of the U-shaped frame. A square frame is slidably connected inside the sliding groove. A stainless steel plate is fixedly connected inside the square frame.

[0008] Furthermore, the stainless steel plate has a thickness of 1-2 mm, and a spherical protrusion is provided in the middle of the stainless steel plate, with a through hole in the middle of the spherical protrusion.

[0009] Furthermore, both the surface of the stainless steel plate and the surface of the spherical protrusion are provided with uniformly distributed filter holes.

[0010] Furthermore, the drive assembly includes a pull rod and a threaded cylinder. The pull rod passes through a through hole in the middle of the spherical protrusion. The threaded cylinder is fixedly connected to one side of the housing. The side wall of the pull rod is provided with a threaded portion that mates with the threaded cylinder. One end of the pull rod is fixedly connected to a handle. The side wall of the pull rod is provided with four nuts. The four nuts are arranged in pairs, and the two nuts in the same pair are respectively located on both sides of the corresponding spherical protrusion.

[0011] Furthermore, the spray assembly includes a spray pipe fixedly connected to the top of the second separation chamber, and spray nozzles evenly distributed are fixedly installed on the bottom of the side wall of the spray pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the exhaust gas first passes through the large-pore filter component, and the solid particles in the exhaust gas are separated. Then, it enters the interior of the second separation chamber, where the dust in the exhaust gas is settled by the spray component. The dust and solid particles are separated separately, which not only avoids the solid particles from clogging the dust discharge pipe, but also avoids the dust from clogging the large-pore filter component and affecting its service life. The drive component can clean the large-pore filter component, further improving its service life. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1-3 As shown, a dust and solid particle separation device includes a housing 1 and a partition 2. The partition 2 is disposed inside the housing 1, dividing the interior of the housing 1 into a first separation chamber 3 and a second separation chamber 4. A vent 21 for connecting the first separation chamber 3 and the second separation chamber 4 is disposed at the top of the partition 2. A large-pore filter assembly 5 is disposed inside the first separation chamber 3. A drive assembly 6 for pulling the large-pore filter assembly 5 is disposed in the middle of the first separation chamber 3, and the drive assembly 6 passes through the large-pore filter assembly. In the middle of component 5, a spray assembly 7 is provided on the top of the inner side of the second separation chamber 4. An air inlet pipe 11 and an air outlet pipe 12 are fixedly connected to the two ends of the top of the outer shell 1, respectively. The bottom ends of the first separation chamber 3 and the second separation chamber 4 are both cone-shaped. The bottom ends of the first separation chamber 3 and the second separation chamber 4 are fixedly connected to the particle discharge pipe 13 and the dust discharge pipe 14, respectively. A valve 15 is provided on the top of the particle discharge pipe 13 and the top of the dust discharge pipe 14. A cover plate 16 is fixedly connected to the top of the outer shell 1.

[0021] According to the above structure, during use, the exhaust gas is introduced into the interior of the first separation chamber 3 through the air inlet pipe 11. The exhaust gas passes through the large-pore filter component 5, and the solid particles in the exhaust gas are separated. After passing through the large-pore filter component 5, the exhaust gas enters the interior of the second separation chamber 4 through the air vent 21. After being sprayed by the spray component 7, the dust in the exhaust gas settles down. The dust and solid particles are separated separately. This not only avoids solid particles from clogging the dust discharge pipe 14, but also avoids dust from clogging the large-pore filter component 5 and affecting the service life of the large-pore filter component 5.

[0022] like Figure 3 and 4As shown, the large-pore filter assembly 5 has two layers. The large-pore filter assembly 5 includes a U-shaped frame 51 fixedly connected inside the first separation chamber 3. A sliding groove 52 is provided on the inner side of the U-shaped frame 51. A square frame 53 is slidably connected inside the sliding groove 52. A stainless steel plate 54 is fixedly connected inside the square frame 53. The thickness of the stainless steel plate 54 is 1-2 mm. A spherical protrusion 55 is provided in the middle of the stainless steel plate 54. A through hole is provided in the middle of the spherical protrusion 55. The surface of the stainless steel plate 54 and the surface of the spherical protrusion 55 are both provided with uniformly distributed filter holes 56.

[0023] According to the above structure, during use, the exhaust gas enters the interior of the first separation chamber 3 from the intake pipe 11. The exhaust gas passes through the filter hole 56, and the solid particles in the exhaust gas are filtered out. The spherical protrusion 55 can undergo elastic deformation. After a period of use, by pulling the spherical protrusion 55, it can deform to facilitate the falling off of the particles attached to the surface of the spherical protrusion 55 and prevent blockage.

[0024] like Figure 3 and 4 As shown, the drive assembly 6 includes a pull rod 61 and a threaded cylinder 62. The pull rod 61 passes through a through hole in the middle of the spherical protrusion 55. The threaded cylinder 62 is fixedly connected to one side of the housing 1. The side wall of the pull rod 61 is provided with a threaded part 63 that mates with the threaded cylinder 62. One end of the pull rod 61 is fixedly connected to a handle 64. The side wall of the pull rod 61 is provided with four nuts. The four nuts are arranged in pairs, and the two nuts in the same pair are respectively located on both sides of the corresponding spherical protrusion 55.

[0025] According to the above structure, when removing particles from the surface of the spherical protrusion 55, the handle 64 is turned to move the pull rod 61 outward, thereby deforming the spherical protrusion 55. After the threaded part 63 is unscrewed from the inside of the threaded cylinder 62, the handle 64 is repeatedly pulled to deform the spherical protrusion 55 repeatedly, which makes it easier to shake off the solid particles on the surface of the spherical protrusion 55. After shaking several times, the threaded part 63 is screwed into the inside of the threaded cylinder 62 to seal the threaded cylinder 62.

[0026] like Figure 3 As shown, the spray assembly 7 includes a spray pipe 71 fixedly connected to the top of the second separation chamber 4, and spray nozzles 72 evenly distributed are fixedly installed on the bottom of the side wall of the spray pipe 71.

[0027] According to the above structure, the exhaust gas with solid particles removed enters the interior of the second separation chamber 4, and the spray pipe 71 is connected to an external water source. Water is sprayed out through the nozzle 72, thereby settling the dust in the air.

[0028] The working principle of this utility model is as follows: During use, the exhaust gas passes through the large-aperture filter assembly 5 and enters the interior of the second separation chamber 4 through the vent 21. After being sprayed by the spray assembly 7, the dust in the exhaust gas settles, and the dust and solid particles are separated. This not only prevents solid particles from clogging the dust discharge pipe 14, but also prevents dust from clogging the large-aperture filter assembly 5 and affecting its service life. During use, the exhaust gas enters the interior of the first separation chamber 3 from the inlet pipe 11. The exhaust gas passes through the filter holes 56, and the solid particles in the exhaust gas are filtered out. The spherical protrusion 55 can undergo elastic deformation. After a period of use, by pulling the spherical protrusion 55, it can deform to facilitate the spherical... The particles attached to the surface of the spherical protrusion 55 fall off to prevent blockage. When removing particles from the surface of the spherical protrusion 55, the handle 64 is turned to move the lever 61 outward, thereby deforming the spherical protrusion 55. After the threaded part 63 is unscrewed from the inside of the threaded cylinder 62, the handle 64 is repeatedly pulled to deform the spherical protrusion 55 repeatedly, which makes it easier to shake off the solid particles on the surface of the spherical protrusion 55. After shaking several times, the threaded part 63 is screwed into the inside of the threaded cylinder 62 to seal the threaded cylinder 62. The exhaust gas with solid particles removed enters the second separation chamber 4. The spray pipe 71 is connected to the external water source, and water is sprayed out through the nozzle 72, thereby settling the dust in the air.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
