Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to an advanced dust removal device that is easy to adjust. Background Technique

[0002] A dust collector is a device that separates dust from flue gas, also known as a dust removal device.

[0003] In the prior art, there are various dust collectors used for dust removal, and their functional principles are also different. Generally, there are dry mechanical dust collectors, bag dust collectors, electrostatic dust collectors, and cyclone dust collectors, etc. This application document mainly focuses on improving the cyclone dust collector.

[0004] A cyclone dust collector is a common dust removal device with a simple structure, convenient operation, and low cost. Its working principle is to use the centrifugal force generated by the rotating airflow to separate dust particles from the airflow. The dust-containing gas enters the dust collector at a high speed along the tangential direction, forms a strong rotating airflow inside the dust collector, the dust is thrown towards the wall under the action of centrifugal force, and falls into the ash hopper along the wall surface, while the purified gas is discharged from the center of the dust collector.

[0005] However, such cyclone dust collectors in the prior art have relatively low capture efficiency for fine particles, resulting in limited dust removal effect. Therefore, an advanced dust removal device that is easy to adjust is needed to improve this problem. Content of the Utility Model

[0006] The purpose of the utility model is to provide an advanced dust removal device that is easy to adjust to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: an advanced dust removal device that is easy to adjust, including a support frame. In the middle of the inner side of the support frame, a cyclone dust collector is fixedly arranged. The cyclone dust collector includes a housing, an air inlet pipe, a collection hopper, and a return air pipe. In the middle of the inner side of the support frame, a housing is fixedly arranged. On one side of the housing surface, an air inlet pipe is fixedly arranged. At the lower end of the housing, a collection hopper is fixedly arranged. In the middle of the inner side of the housing, a return air pipe is fixedly arranged. A secondary filtration mechanism for improving the filtration effect of the device is arranged between the housing and the upper end of the support frame. The secondary filtration mechanism includes a bracket, a fixed frame, a filter pipe, a straight-through pipe, a fixed block, and an air outlet pipe. A bracket is fixedly arranged between the housing and the upper end of the support frame. At the upper end of the bracket, a fixed frame is fixedly arranged. In the middle of the inner side of the fixed frame, a filter pipe is movably engaged. On one side of the filter pipe inside the fixed frame, a straight-through pipe is movably engaged. A fixed block is fixedly arranged between the straight-through pipe and the filter pipe. In the middle of the upper end of the fixed frame, an air outlet pipe is fixedly arranged.

[0008] Preferably, through grooves are formed in the middle and on both sides of the outer surface of the fixed frame. The middle part of the lower end of the fixed frame is fixedly connected to the return air pipe through the through groove. The air that has undergone cyclone dust removal in the return air pipe can enter the middle of the fixed frame through the through groove. If the middle part of the fixed frame is a filter pipe, the air can be filtered again to improve the filtering effect. If it is a straight pipe, similar to the cyclone dust collector in the prior art, the air that has undergone preliminary cyclone dust removal will directly be discharged from the straight pipe and the exhaust pipe. The through grooves on both sides can be used as inspection holes for inspecting the filter pipe or the straight pipe.

[0009] Preferably, a filter element is arranged inside the filter pipe. Through the filter element, the air that has undergone cyclone dust removal can be finely filtered again, thereby improving the filtering effect of the device. The air flow path for filtering is as follows: The air enters the middle part inside the filter element through the return air pipe, then passes through the filter element and enters the space between the filter element and the inner side wall of the filter pipe (the air is filtered when it enters the space between the filter element and the inner side wall of the filter pipe from the middle part inside the filter element), and finally enters the outlet pipe from the filter pipe, and then is discharged into the equipment of the next process through the pipe.

[0010] Preferably, an electric push rod is fixedly arranged on the surface of the bracket. The movable end of the electric push rod is fixedly connected to the fixed block. By the telescoping of the electric push rod, the fixed block, the filter pipe, and the straight pipe can be driven to move, so that the straight pipe or the filter pipe is aligned with the return air pipe.

[0011] Preferably, sealing rings are fixedly arranged at the upper and lower ends of the outer surface of the straight pipe and the filter pipe. Through the sealing rings, the straight pipe and the filter pipe are fixed in the fixed frame in an interference fit manner, which can ensure the sealing performance between the straight pipe, the filter pipe, and the inner side wall of the fixed frame.

[0012] Preferably, a connecting flange is fixedly arranged at the lower end of the collection hopper. A collection bag is fixedly arranged at the lower end of the connecting flange. The collection bag can be used to collect the dust thrown out by the cyclone dust collector by centrifugal force. At the same time, when cleaning the dust, the dust inside the filter element can also fall into the collection bag from the return air pipe during dust cleaning. When cleaning the dust, the air intake is paused, and then the whole device is vibrated by a vibration motor (not shown in the figure). In this way, the dust inside the collection hopper can directly slide into the collection bag, and the dust filtered by the filter element inside, after being vibrated and shaken off, falls into the collection bag through the return air pipe under the action of gravity for dust removal.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The filter element in the filter tube of the present utility model can filter the air again to improve the filtering effect. If it is a straight-through tube, it is the same as the cyclone dust collector in the prior art, and the air preliminarily dust-removed by cyclone directly discharges from the straight-through tube and the exhaust pipe. The filter tube can increase the filtering effect of the device, resulting in a good filtering effect, while the straight-through tube has a high ventilation efficiency. Thus, the device can be selected between a good filtering effect and a high ventilation rate, thereby further improving the use effect of the device.

[0015] 2. The adjustment of the filter tube and the straight-through tube of the present utility model can be completed by the extension and contraction of the electric push rod, which is convenient for adjustment. And each time of adjustment, it will align the non-working pipeline with the through slots on both sides. At this time, the through slots on both sides can be used as inspection holes for inspecting the filter tube or the straight-through tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: an easily adjustable advanced dust removal device, including a support frame 1. In the middle of the inner side of the support frame 1, a cyclone dust collector is fixedly arranged. The cyclone dust collector includes a housing 2, an air inlet pipe 3, a collection hopper 4, and a return air pipe 5. In the middle of the inner side of the support frame 1, a housing 2 is fixedly arranged. On one side of the surface of the housing 2, an air inlet pipe 3 is fixedly arranged. At the lower end of the housing 2, a collection hopper 4 is fixedly arranged. In the middle of the inner side of the housing 2, a return air pipe 5 is fixedly arranged. A secondary filtration mechanism for improving the filtration effect of the device is arranged between the housing 2 and the upper end of the support frame 1. The secondary filtration mechanism includes a bracket 6, a fixed frame 7, a filter pipe 8, a straight-through pipe 9, a fixed block 10, and an air outlet pipe 11. A bracket 6 is fixedly arranged between the housing 2 and the upper end of the support frame 1. At the upper end of the bracket 6, a fixed frame 7 is fixedly arranged. In the middle of the inner side of the fixed frame 7, a filter pipe 8 is movably engaged. In the fixed frame 7, on one side of the filter pipe 8, a straight-through pipe 9 is movably engaged. Between the straight-through pipe 9 and the filter pipe 8, a fixed block 10 is fixedly arranged. In the middle of the upper end of the fixed frame 7, an air outlet pipe 11 is fixedly arranged.

[0023] In the middle and on both sides of the outer surface of the fixed frame 7, through grooves 12 are opened. At the middle of the lower end of the fixed frame 7, through the through grooves 12, it is fixedly connected to the return air pipe 5. The air that has undergone cyclone dust removal in the return air pipe 5 can enter the middle of the fixed frame 7 through the through grooves 12. If the middle of the fixed frame 7 is a filter pipe 8, the air can be filtered again to improve the filtration effect. If it is a straight-through pipe 9, it is the same as the cyclone dust collector in the prior art, and the air that has undergone preliminary cyclone dust removal is directly discharged from the straight-through pipe 9 and the exhaust pipe. The through grooves 12 on both sides can be used as inspection holes for inspecting the filter pipe 8 or the straight-through pipe 9.

[0024] Inside the filter pipe 8, a filter element 13 is arranged. Through the filter element 13, the air that has undergone cyclone dust removal can be finely filtered again, thereby improving the filtration effect of the device. The air flow path for filtration is that the air enters the middle of the inner side of the filter element 13 through the return air pipe 5, then passes through the filter element 13 and enters the space between the filter element 13 and the inner side wall of the filter pipe 8 (the air is filtered when it enters the space between the filter element 13 and the inner side wall of the filter pipe 8 from the middle of the inner side of the filter element 13), and finally enters the air outlet pipe 11 from the filter pipe 8, and then is discharged into the equipment of the next process through the air pipe.

[0025] On the surface of the bracket 6, an electric push rod 14 is fixedly arranged. The movable end of the electric push rod 14 is fixedly connected to the fixed block 10. Through the telescoping of the electric push rod 14, the fixed block 10, the filter pipe 8, and the straight-through pipe 9 can be driven to move, so that the straight-through pipe 9 or the filter pipe 8 is aligned with the return air pipe 5.

[0026] Sealing rings are fixedly arranged at the upper and lower ends of the outer surfaces of the straight-through pipe 9 and the filter pipe 8. Through the sealing rings, the straight-through pipe 9 and the filter pipe 8 are press-fitted and fixed inside the fixed frame 7, which can ensure the sealing between the straight-through pipe 9, the filter pipe 8 and the inner side wall of the fixed frame 7.

[0027] A connecting flange 15 is fixedly arranged at the lower end of the collecting hopper 4, and a collecting bag 16 is fixedly arranged at the lower end of the connecting flange 15. The collecting bag 16 can be used to collect the dust thrown out by the cyclone dust collector by centrifugal force. At the same time, when cleaning the dust, the dust inside the filter element 13 can also fall into the collecting bag 16 from the return air pipe 5 during dust cleaning. When cleaning the dust, the air intake is paused, and then the whole device is vibrated by a vibration motor (not shown in the figure). In this way, the dust inside the collecting hopper 4 can directly slide into the collecting bag 16, and the dust filtered by the filter element 13 inside the filter pipe 8 falls into the collecting bag 16 under the action of gravity after being vibrated and shaken for dust removal.

[0028] Working principle: When using this device, the air to be processed can be introduced into the housing 2 through the air inlet pipe 3. Subsequently, the air rotates inside the housing 2 and most of the dust is thrown off under the action of centrifugal force to reduce the working intensity of the subsequent filter pipe. The dust accumulates along the inner side wall of the collecting hopper 4 at the lower end inside the collecting hopper 4, and the air is discharged upward through the return air pipe 5. At this time, the air discharged through the return air pipe 5 can enter the middle part of the fixed frame 7 through the through groove 12. If the middle part of the fixed frame 7 is the filter pipe 8, the air can enter the filter pipe 8. At this time, the air can be filtered again by the filter element 13 in the filter pipe 8 to improve the filtering effect. If it is the straight-through pipe 9, it is the same as the cyclone dust collector in the prior art, and the air preliminarily dust-removed by the cyclone directly discharges from the straight-through pipe 9 and the exhaust pipe. The filter pipe 8 can improve the filtering effect of the device, making the filtering effect good, while the straight-through pipe 9 has high ventilation efficiency. In this way, this device can choose between high filtering effect and high ventilation rate, thereby further improving the use effect of this device. The adjustment of the filter pipe 8 and the straight-through pipe 9 can be completed by the extension and contraction of the electric push rod 14, and the adjustment is convenient. Each time an adjustment is made, the non-working pipe will be aligned with the through grooves 12 on both sides. At this time, the through grooves 12 on both sides can be used as inspection holes for inspecting the filter pipe 8 or the straight-through pipe 9.
