Description

Technical Field

[0001] This utility model relates to dust purification, and in particular to a dust purification device for workshop processing. Background Technology

[0002] Dust purification devices are specialized equipment used to capture, separate, and purify particulate matter in the air. They are widely used in industrial production, environmental protection projects, and other fields. Their core function is to reduce dust emissions and minimize harm to the environment and human health. They can also recycle high-value dust, enabling resource reuse.

[0003] As the dust purification equipment used in current workshops is used, the filter plates and other structures may become clogged or even damaged over time, resulting in excessive resistance and reduced dust removal efficiency. Even if the existing equipment uses a back-blowing device, the back-blowing direction forms a convection with the airflow direction, which not only affects the dust purification efficiency of the equipment, but also makes it difficult to effectively clean the dust adsorbed on the filter plates. Utility Model Content

[0004] The purpose of this invention is to provide a dust purification device for workshop processing to solve the technical problems in the prior art. It can adjust the airflow direction in the purification box according to the amount of dust on the filter plate, and can also back-blow the filter plate with purified air to clean the filter plate with a large amount of dust adsorption. This not only ensures the dust removal efficiency of the equipment, but also reduces the resistance of the equipment.

[0005] This utility model provides a dust purification device for workshop processing, comprising: a purification box, an air inlet pipe fixedly connected inside the purification box, and a flow diversion mechanism inside the air inlet pipe for adjusting the flow direction of gas inside the purification box; a first filter plate, a second filter plate, and a purification plate, all disposed inside the purification box, wherein the first filter plate and the second filter plate are slidably connected to the purification box, and the purification plate is fixedly connected to the purification box; a detection mechanism disposed on the side of the purification box near the first filter plate and the second filter plate for detecting the amount of dust adsorbed on the first filter plate and the second filter plate; a back-blowing mechanism disposed on the side of the purification box near the first filter plate and the second filter plate, wherein when gas flows along one side of the purification box, the back-blowing mechanism back-blowing the first filter plate and the second filter plate on the other side of the purification box; and an exhaust pipe symmetrically connected to both sides of the purification box, wherein a return pipe is disposed on the exhaust pipe.

[0006] In the technical solution of this application embodiment, when purifying dust in the air of the processing workshop, the air in the workshop is adsorbed by a diversion mechanism. Initially, the adsorbed air flows along one side of the purification box and intercepts dust of different particle sizes in the air through the first filter plate and the second filter plate. When the amount of dust adsorbed on the first filter plate or the second filter plate is large, the resistance of the first filter plate or the second filter plate will increase, thereby controlling the diversion mechanism to adjust the airflow direction. At the same time, a portion of the purified clean air can be delivered to the back-blowing mechanism, which drives the back-blowing mechanism to move up and down along the first filter plate or the second filter plate to improve the local back-blowing force of the first filter plate or the second filter plate, thereby improving the dust removal effect on the first filter plate or the second filter plate. This not only ensures the dust removal efficiency of the equipment, but also extends the continuous working time of the equipment.

[0007] Preferably, the diversion mechanism includes a motor housing fixedly connected to the bottom of the air inlet pipe, a rotating shaft fixedly connected to the output end of the motor housing, and a fan wheel fixedly connected to the end of the rotating shaft, for generating negative pressure inside the purification chamber.

[0008] Preferably, it also includes multiple diversion holes symmetrically opened on the side wall of the air inlet duct, an electric slide rail connected to the diversion holes is provided on the inner wall of the air inlet duct, an arc-shaped baffle is provided inside the electric slide rail, and a partition is fixedly connected between the inner wall of the purification box and the air inlet duct to divide the internal space of the purification box.

[0009] Preferably, the detection mechanism includes a fixed plate fixedly connected to the side of the first filter plate and the second filter plate away from the air inlet pipe. Multiple sets of springs are fixedly connected between the fixed plate and the first filter plate or the second filter plate. A control switch is fixedly connected to the side of the fixed plate near the first filter plate or the second filter plate. The control switch is electrically connected to the electric slide rail.

[0010] Preferably, the system also includes multiple sets of dust collection bags connected to the bottom of the purification chamber. These dust collection bags are located below the partition and the first filter plate, as well as between the first filter plate and the second filter plate, and are used to collect dust from the first filter plate and the second filter plate.

[0011] Preferably, the backflushing mechanism includes a servo motor fixedly connected to the top of the purification chamber. Reciprocating screws are rotatably connected to the side of the purification chamber near the first and second filter plates. One set of the reciprocating screws is connected to the output end of the servo motor. A backflushing pipe is provided on the reciprocating screw. A limiting rod that is slidably connected to the backflushing pipe is fixedly connected to the inner wall of the purification chamber. A linkage wheel is fixedly connected to both sets of reciprocating screws on the same side. A belt is sleeved between the two sets of linkage wheels. The servo motor is electrically connected to a control switch at a symmetrical position.

[0012] Preferably, the backflush pipe is open on the side near the first and second filter plates, and the return pipe is open at the end near the purification box. The backflush pipe and the return pipe at a symmetrical position are connected by a pipe.

[0013] Compared with the prior art, this utility model can adjust the airflow direction in the purification box according to the amount of dust on the filter plate. At the same time, it can also back-blow the filter plate with purified air to clean the filter plate with a large amount of dust adsorption. This not only ensures the dust removal efficiency of the equipment, but also reduces the resistance of the equipment. Attached Figure Description

[0027] like Figures 1-4 As shown, an embodiment of this utility model provides a dust purification device for workshop processing, comprising: a purification box 2, an air inlet pipe 3 fixedly connected inside the purification box 2, and a flow diversion mechanism inside the air inlet pipe 3 for adjusting the flow direction of the gas inside the purification box 2; a first filter plate 11, a second filter plate 12, and a purification plate 13, all disposed inside the purification box 2, wherein the first filter plate 11 and the second filter plate 12 are slidably connected to the purification box 2, and the purification plate 13 is fixedly connected to the purification box 2; a detection mechanism disposed on the side of the purification box 2 near the first filter plate 11 and the second filter plate 12 for detecting the amount of dust adsorbed on the first filter plate 11 and the second filter plate 12; and a backflushing mechanism. The first filter plate 11 and the second filter plate 12 are placed on one side of the purification box 2. When the gas flows along one side of the purification box 2, the back-blowing mechanism back-blowing the first filter plate 11 and the second filter plate 12 on the other side of the purification box 2. The exhaust pipe 14 is symmetrically connected to both sides of the purification box 2. The exhaust pipe 14 is equipped with a return pipe 25. The first filter plate 11 and the second filter plate 12 are used to intercept large dust particles and small dust particles, respectively. The purification plate 13 can be made of activated carbon or other materials to purify harmful gases in the air. The bottom of the purification box 2 is fixedly connected to a support column 1. The equipment can be moved to a designated location in the processing workshop by setting wheels at the bottom of the support column 1.

[0028] In the technical solution of this application embodiment, when purifying dust in the air of the processing workshop, the air in the workshop is adsorbed by a diversion mechanism. Initially, the adsorbed air flows along one side of the purification box 2 and intercepts dust of different particle sizes in the air through the first filter plate 11 and the second filter plate 12. When the amount of dust adsorbed on the first filter plate 11 or the second filter plate 12 is large, the resistance of the first filter plate 11 or the second filter plate 12 will increase, thereby controlling the diversion mechanism to adjust the airflow direction. At the same time, some of the purified clean air can be delivered to the back-blowing mechanism, which drives the back-blowing mechanism to move up and down along the first filter plate 11 or the second filter plate 12 to improve the local back-blowing force of the first filter plate 11 or the second filter plate 12, thereby improving the dust cleaning effect on the first filter plate 11 or the second filter plate 12. This not only ensures the dust removal efficiency of the equipment, but also extends the continuous working time of the equipment.

[0029] In the embodiments provided in this application, the diversion mechanism includes a motor housing 4 fixedly connected to the bottom of the air inlet pipe 3, a rotating shaft 5 fixedly connected to the output end of the motor housing 4, and a fan wheel 6 fixedly connected to the end of the rotating shaft 5, which is used to generate negative pressure inside the purification box 2.

[0030] The motor housing 4 contains a drive motor, which is a conventional method in the prior art and will not be described in detail. When the drive motor drives the rotating shaft 5 and the impeller 6 to rotate, the impeller 6 will draw the air in the workshop into the purification box 2. In addition, a flexible hose can be connected to the end of the air inlet pipe 3 to facilitate the adsorption of air from different locations in the workshop.

[0031] In the embodiments provided in this application, there are also multiple diversion holes 7 symmetrically opened on the side wall of the air inlet pipe 3, an electric slide rail 8 connected to the diversion holes 7 is provided on the inner wall of the air inlet pipe 3, an arc-shaped baffle 9 is provided inside the electric slide rail 8, and a partition 10 is fixedly connected between the inner wall of the purification box 2 and the air inlet pipe 3 for dividing the internal space of the purification box 2.

[0032] The specific structure of the electric slide rail 8 can be referred to the technical solutions in the prior art, which are known to those skilled in the art and will not be described in detail here. The position of the arc-shaped baffle 9 and the diversion hole 7 can be adjusted by the electric slide rail 8. When the arc-shaped baffle 9 on one side is in contact with the diversion hole 7, the air that enters flows into the purification box 2 through the diversion hole 7 on the other side.

[0033] In the embodiments provided in this application, the detection mechanism includes a fixed plate 16 fixedly connected to the side of the first filter plate 11 and the second filter plate 12 away from the air inlet pipe 3. Multiple sets of springs 17 are fixedly connected between the fixed plate 16 and the first filter plate 11 or the second filter plate 12. A control switch 18 is fixedly connected to the side of the fixed plate 16 near the first filter plate 11 or the second filter plate 12. The control switch 18 is electrically connected to the electric slide rail 8.

[0034] During air purification, the air flows along the direction of the first filter plate 11, the second filter plate 12, and the purification plate 13. When the amount of dust adsorbed on the first filter plate 11 or the second filter plate 12 increases, the resistance on the first filter plate 11 or the second filter plate 12 increases. Under the action of the spring 17, the first filter plate 11 or the second filter plate 12 will gradually move closer to the control switch 18. When it contacts the control switch 18, it will control the electric slide rail 8 to adjust the position of the arc-shaped baffle 9, that is, the diversion hole 7 on the original air flow direction is closed, and the diversion hole 7 on the other side is open, thereby adjusting the air flow direction in the purification box 2. The above control method is a conventional means in the prior art, so it will not be described in detail. At the same time, as the amount of dust on the first filter plate 11 and the second filter plate 12 changes, the first filter plate 11 and the second filter plate 12 can also be driven by the spring 17 to vibrate, so that the dust on the first filter plate 11 and the second filter plate 12 can be automatically detached, further improving the dust removal efficiency of the equipment.

[0035] In the embodiments provided in this application, multiple sets of dust collection bags 15 are connected to the bottom of the purification box 2. The dust collection bags 15 are respectively located below the partition 10 and the first filter plate 11 and the first filter plate 11 and the second filter plate 12, and are used to collect dust on the first filter plate 11 and the second filter plate 12.

[0036] It should be explained that the shape and material of the dust collection bag 15 can be adjusted according to the type of dust in the processing workshop, which will not be elaborated here.

[0037] In the embodiments provided in this application, the backflushing mechanism includes a servo motor 19 fixedly connected to the top of the purification chamber 2. A reciprocating screw 20 is rotatably connected to one side of the purification chamber 2 near the first filter plate 11 and the second filter plate 12. One set of reciprocating screws 20 is connected to the output end of the servo motor 19. A backflushing pipe 22 is provided on the reciprocating screw 20. A limiting rod 21 that is slidably connected to the backflushing pipe 22 is fixedly connected to the inner wall of the purification chamber 2. A linkage wheel 23 is fixedly connected to the two sets of reciprocating screws 20 on the same side. A belt 24 is sleeved between the two sets of linkage wheels 23. The servo motor 19 is electrically connected to a control switch 18 at a symmetrical position.

[0038] When the first filter plate 11 or the second filter plate 12 contacts the control switch 18, the servo motor 19 on the corresponding side is turned on, thereby driving the reciprocating screw 20 to rotate. It should be explained that the reciprocating screw 20 is a conventional means in the prior art. The backflush pipe 22 is provided with balls or protrusions that match the reciprocating screw 20. At this time, the backflush pipe 22 will drive the backflush pipe 22 to move up and down along the first filter plate 11 and the second filter plate 12, thereby increasing the local backflush force of the first filter plate 11 and the second filter plate 12, and thus improving the dust cleaning effect on the first filter plate 11 and the second filter plate 12. In addition, the linkage wheel 23 and the belt 24 can make the two sets of reciprocating screws 20 rotate synchronously.

[0039] In the embodiments provided in this application, the backflush pipe 22 is open on the side near the first filter plate 11 and the second filter plate 12, and the return pipe 25 is open at the end near the purification box 2. The backflush pipe 22 and the return pipe 25 at the symmetrical position are connected by a pipe.

[0040] The open design of the return pipe 25 ensures the stability of gas flow. When air flows along one side, the purified air flows through the return pipe 25 to the first filter plate 11 and the second filter plate 12 on the other side. This ensures the dust removal efficiency of the equipment and reduces the energy consumption of the equipment during dust removal.

[0041] The above description is only a preferred embodiment of the present utility model. However, the scope of the present utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of the present utility model.
