DETAILED DESCRIPTION

[0027] 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 of 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.

[0028] Embodiment 1:

[0029] like Figures 1 to 9 As shown, an air filter comprises a shell 102, on which an air inlet 101 and an air outlet 103 are fixedly mounted, a filter assembly 3 is arranged in the shell 102, the filter assembly 3 comprises a plurality of processing units, each processing unit is a V-shaped structure, a processing unit comprises a plurality of throttle plates 305, both ends of the throttle plates 305 are fixedly connected with side plates 303, the plurality of throttle plates 305 and the side plates 303 form a plurality of air flow channels, the air flow channels are wavy, and the side plates 303 are V-shaped. The throttle plate 305 is arranged in a V shape on the side plate 303, and the side plate 303 is fixedly connected with a cross plate 301 and an arc-shaped guide plate 304. When the gas passes through the throttle plate 305, it is turned through the air flow channel and the flow rate of the gas is reduced so that the dust in the gas slowly settles and is then collected by the throttle plate 305; the air inlets of multiple filtering processing units are connected to the air inlet 101, and the air outlet channels formed between adjacent filtering processing units and between the filtering processing units and the side walls of the shell are connected to the air outlet 103.

[0030] When in use, the mounting assembly 2 on the air inlet 101 is connected to the blower, and the mounting assembly 2 on the air outlet 103 is connected to the output pipe. This device is used in coal-fired unit projects. The air in the working environment is input through the blower, and the clean gas is supplied to the coal-fired unit after being filtered by the device. A switch is provided on the ash discharge port 104. When working, the switch on the ash discharge port 104 is closed, so that air enters from the air inlet 101 and is discharged from the air outlet 103. At this time, the pressure of the input gas of the air inlet 101 is the same as the pressure of the output gas of the air inlet 101, and is filtered by the pressure difference. When it is necessary to discharge dust, the switch of the pipe on the air outlet 103 is closed, and the switch on the ash discharge port 104 is opened, so that the pressure of the input airflow on the air inlet 101 is large, and the pressure of the gas discharged from the ash discharge port 104 is small, forming a pressure difference, and then the dust filtered on the filter assembly 3 is discharged.

[0031] Example 2.

[0032] like Figures 6 to 9 As shown, the throttle plate 305 is fixedly connected with a connecting rod 306 and a connecting plate 302, and a plurality of throttle plates 305 are fixed by the connecting rod 306 and the connecting plate 302 to enhance their stability.

[0033] The arc guide plate 304 is set to be arc-shaped, and the inner arc surface of the arc guide plate 304 fits the throttle plates 305 on the two connecting rods 306. The arc guide plate 304 guides the airflow to enter the V-shaped structure of each processing unit.

[0034] The shell 102 is fixedly provided with an ash discharge port 104 , and an air outlet passage formed between the filtering processing unit and the side wall of the shell is also communicated with the ash discharge port 104 .

[0035] like Figure 1 and Figure 6 As shown, the filter assembly 3 is turned over 90 degrees so as to be installed in the housing 102, that is, the side plate 303 is installed on the side away from the ash discharge port 104. Figure 6 The structure at A in the middle corresponds to the direction of the ash discharge port 104 .

[0036] When in use, the outside air is input through the air inlet 101 and pressurized by the blower. After the gas enters the air inlet 101, the gas is divided by the arc guide plate 304 and enters the interior of different large V-shaped structures, that is, Fig. 9 The gas flows through the area at D in the middle, thereby dividing the gas. When the gas passes through the throttle plate 305, the direction of the gas flow is changed. The gas flow is gradually compressed in space, thereby being decelerated and adsorbed on the throttle plate 305. Then, driven by the gas flow, the gas passes through the gaps between the multiple throttle plates 305 and enters the area between the two large V-shaped structures, that is, Fig. 9The dust in the air flow enters the area at point C in the middle, and the gas is discharged through the air outlet 103. In this process, the dust in the air flow enters between the two throttle plates 305 from the D area, and the air flow is slowed down to a very slow speed at the corner of the throttle plate 305. Because the air pressure of the air flow entering the air inlet 101 and the air outlet 103 is the same, the dust stays on the inclined plate on the lower side of the throttle plate 305, so that the clean gas continues to enter point C along the throttle plate 305, and finally the gas at each point C is collected at the air outlet 103, and then discharged through the air outlet 103.

[0037] When dust discharge is required, close the switch of the pipeline at the air outlet 103 and open the switch at the ash discharge port 104. Because the gas flow rate input from the air outlet 103 is greater than the gas flow rate discharged from the ash discharge port 104, the dust on the throttle plate 305 is driven from D to C through the pressure difference, and then the dust is discharged through the ash discharge port 104.

[0038] Embodiment three:

[0039] like Figures 2 to 5 As shown, the air inlet 101 and the air outlet 103 are provided with a mounting assembly 2, and the mounting assembly 2 includes an inner mounting ring 204, and the inner mounting ring 204 is fixedly connected to the air inlet 101, and an outer convex ring is provided on the end of the inner mounting ring 204 away from the shell 102, and the first end of the inner buffer spring 203 is fixedly connected to the outer convex ring, and the end of the inner mounting ring 204 close to the shell 102 is slidably connected to the inner convex ring of the first end of the outer buffer ring 202, the inner convex ring is fixedly connected to the second end of the inner buffer spring 203, and the second end of the outer buffer ring 202 is slidably connected to the outer convex ring of the inner mounting ring 204, and is connected to an external device through the outer buffer ring 202.

[0040] The first end of the outer sliding ring 205 is slidably connected to the inner mounting ring 204, and the second end of the outer sliding ring 205 is provided with an outer convex ring, on which the inner convex ring of the connecting ring 201 is fixedly installed. The connecting ring 201 pushes the outer buffer ring 202 to slide on the inner mounting ring 204 to achieve buffering.

[0041] The first end of the outer sliding ring 205 is slidably connected to the inner mounting ring 204, and the second end of the outer sliding ring 205 is provided with an outer convex ring, on which the inner convex ring of the connecting ring 201 is fixedly installed. The connecting ring 201 pushes the outer buffer ring 202 to slide on the inner mounting ring 204 to achieve buffering.

[0042] The first end of the telescopic rod 207 is rotatably connected to the outer sliding ring 205, the second end of the telescopic rod 207 is rotatably connected to the connecting block 206, the connecting block 206 is fixedly mounted on the second end of the outer buffer ring 202, and an outer buffer spring 208 is provided on the telescopic rod 207, the first end of the outer buffer spring 208 is fixedly connected to the first end of the telescopic rod 207, and the second end of the outer buffer spring 208 is fixedly connected to the second end of the telescopic rod 207. The torsion of the external device is buffered by the extension and retraction of the telescopic rod 207 and the rotation of the outer sliding ring 205.

[0043] The connecting ring 201 is provided with a plurality of bolt holes, which are connected to the pipe and the air outlet pipe of the blower through bolts.

[0044] When in use, the blower and the air outlet duct are connected to the connecting ring 201. During installation, the duct will push the connecting ring 201. The connecting ring 201 pushes the outer buffer ring 202 to slide on the inner mounting ring 204 through the outer sliding ring 205, the connecting block 206 and the telescopic rod 207, and stretches the inner buffer spring 203 on the inner mounting ring 204, thereby forming a buffer to avoid excessive impact force generated when the duct and the connecting ring 201 are docked. In addition, due to the position, in some cases, the installation hole position of the duct and the hole position of the connecting ring 201 may not be the same, and there is a deviation. At this time, the connecting ring 201 needs to be rotated, and the connecting ring 201 drives the outer sliding ring 205 to rotate on the inner mounting ring 204, and pulls the telescopic rod 207 to make the telescopic rod 207 telescopic, thereby stretching the outer buffer spring 208 on the telescopic rod 207, and then realizing the alignment of the hole position of the duct and the connecting ring 201.

[0045] During operation, the vibration of the blower will be transmitted to the connecting ring 201 through the pipeline, thereby performing multi-directional buffering through the telescopic rod 207, the outer buffer spring 208 and the inner buffer spring 203, that is, the outer buffer ring 202 slides on the inner mounting ring 204 and stretches the inner buffer spring 203 to perform axial buffering, that is, the buffering in the center direction of the circle of the outer buffer ring 202, and the outer sliding ring 205 rotates on the inner mounting ring 204, and drives the telescopic rod 207 and the outer buffer spring 208 to expand and contract, thereby performing lateral rotation buffering, that is, the buffering of left and right rotation on the connecting surface of the connecting ring 201.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
