Patent publication number CN219442860U discloses a dust collection device for plate processing and cutting. The utility model sets the suction device at the bottom of the cutting table and opens a strip-shaped negative pressure port on the table for negative pressure suction, which effectively prevents the dust from blowing. The dust removal effect is much better than that of the upper suction. At the same time, the dust can be tightly adhered by the designed dust collection device, which is convenient for dust collection and has a buffering effect on the direct suction of the fan. A dust treatment device is disclosed. When the dust treatment device is in use, dust generated by a plate processing and cutting machine when cutting a plate enters a plate cutting chamber. An operator turns on a suction pump, and the dust is sucked into the suction pipe group from the plate cutting chamber, and enters a dust removal mechanism through the second end of the suction pipe group. The dust is soaked and dissolved in the dust removal mechanism, and finally excess dust is discharged from the dust treatment device. During the entire process, the processed plate does not need to be wetted with water to complete the treatment of dust generated by cutting the plate, and the dust treatment efficiency is also improved by arranging the suction pump.

[0004] Although the above patent can collect and process the dust generated by plate cutting, it still has the following disadvantages: 1. After the dust is collected, the settling speed is slow, which makes it easy for the dust to float out of the device, causing secondary pollution; 2. When the dust is collected in the device for atomization and sedimentation, the dust flow rate is too fast, so the atomized particles cannot adsorb the dust particles well, resulting in poor sedimentation effect. Summary of the invention

DETAILED DESCRIPTION

[0022] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Embodiment 1. This embodiment aims to provide a dust control and collection device for plate cutting at a construction site, which is mainly used to collect the dust airflow and perform sedimentation treatment. Although there are devices for collecting the dust airflow at this stage, the atomized particles cannot adsorb the dust particles well due to the excessively fast flow rate of the dust airflow, resulting in poor sedimentation effect. In this embodiment, when the dust airflow flows into the three-way tank body 1, a part of the airflow will flow into the counter-jet nozzle through the lower air outlet structure 202 to form a collision with the dust airflow flowing into the upper air outlet structure 201, so as to slow down the flow rate of the dust airflow flowing into the upper air outlet structure 201 and improve the atomization effect.

[0024] Based on the above problems, Figure 1 and Figure 2 As shown, by setting the exhaust port 3 and the storage tank 102, the settled gas can be discharged and the settled particles can be collected.

[0025] Specifically, a transversely arranged air inlet 2 is provided on the three-way tank body 1. The setting of the air inlet 2 enables the cutting device to be aligned with the air inlet 2 when working, so as to collect the dust and discharge the gas through the exhaust port 3. The three-way tank body 1 cannot form a pressure, which prevents the dust from entering the three-way tank body 1 and turning over all the time. The three-way tank body 1 itself is provided with an arc, so that the dust can be transferred to the storage tank 102 along the edge. The bottom of the three-way tank body 1 is detachably connected to the storage tank 102, the air inlet 2 is transversely arranged on the right side of the three-way tank body 1, and the exhaust port 3 is fixedly arranged on the top of the three-way tank body 1. Since the storage tank 102 is detachably connected to the three-way tank body 1 by thread, the storage tank 102 can be removed for replacement or cleaning when it is full.

[0026] like Figure 2 , Figure 4 and Figure 5 As shown, the dust-raising airflow enters the lower air outlet structure 202, so that it can be transmitted to the counter-jet nozzle 403 and collide with the dust-raising airflow flowing into the upper air outlet structure 201, thereby slowing down the flow rate flowing into the upper air outlet structure 201 and improving the adsorption effect of atomized particles.

[0027] Specifically, the hedging mechanism 4 includes a partition plate 401, an air flow pipe 402 and a hedging nozzle 403. The partition plate 401 is fixedly arranged at the air inlet 2, and divides the air inlet 2 into an upper air outlet structure 201 and a lower air outlet structure 202 arranged at intervals. The air flow pipe 402 is laid in the lower air outlet structure 202. The hedging nozzle 403 is arranged on the three-way tank body 1, and corresponds to the upper air outlet structure 201 on the left and right. The air flow pipe 402 is used to connect with the hedging nozzle 403. In the figure, the air inlet is divided into an upper air inlet structure 201 and a lower air inlet structure 202 by a dividing plate 401. The dust airflow flowing in from the lower air inlet structure 202 can be transmitted to the counter-jet head 403 through the air flow pipe 402, so that the airflow discharged from the counter-jet head 403 collides with the dust airflow flowing into the upper air inlet structure 201 to slow down the flow rate of the dust airflow, and then the dust airflow is discharged through the counter-jet head 403 to collide with the dust airflow of the upper air inlet structure 201.

[0028] like Figure 2As shown, the lower air outlet structure 202 is fixedly provided with an interception net 9 to intercept oversized particles; a guide pipe 10 is fixedly provided on the three-way tank body 1, one end of the guide pipe 10 is connected to the lower air outlet structure 202 and is located on the right side of the interception net 9; the other end of the guide pipe 10 is connected to the storage tank 102, so that the intercepted particles flow into the storage tank 102 through the guide pipe 10. Since the dust-raising airflow passing through the lower air outlet structure 202 will also be accompanied by some large particles, these large particles will block the counter-jet nozzle 403, resulting in the counter-jet nozzle 403 being unable to spray gas, thereby reducing the collision effect.

[0029] like Figure 1 and Figure 2 As shown, the upper air outlet structure 201 gradually increases from the air inlet to the inside, so that the air flow velocity decreases; the lower air outlet structure 202 gradually decreases from the air inlet to the inside, so that the dust-raising air flow velocity flowing into the lower air outlet structure 202 increases, so as to flow through the air flow pipe 402 to the counter-jet nozzle 403.

[0030] like Figure 2 and Figure 4 As shown, a flow rate sensor 6 is installed on the upper air outlet structure 201. In this embodiment, the flow rate sensor 6 adopts a thermal wind speed sensor, and its model is JT1401. The flow rate sensor 6 is controlled and connected to the hedging mechanism 4 to control the opening and closing of the hedging jet head 403 and the vertical jet head 8.

[0031] Specifically, the air flow pipe 402 is connected to the counter-jet nozzle 403 through the solenoid valve 7. In this embodiment, the solenoid valve 7 is connected to the signal of the flow rate sensor 6. The three-way tank body 1 and the dividing plate 401 are respectively fixed with vertical jet heads 8 arranged vertically. The vertical jet head 8 is connected to the solenoid valve 7 to control the opening and closing of the counter-jet nozzle 403 and the vertical jet head 8.

[0032] In this embodiment, the air flow velocity is V1>V2>V3. When the flow velocity sensor 6 detects that the flow velocity of the dust-raising air flow is V3, the vertical jet head 8 is driven to open by the solenoid valve 7, so that the airflow flowing into the upper air outlet structure 201 is blocked and the flow velocity of the air flow is slowed down. When the flow velocity sensor 6 detects that the flow velocity is V2, the vertical jet head 8 is closed by the solenoid valve 7, and the counter jet head 403 is opened, so that it collides with the airflow flowing into the upper air outlet structure 201, thereby improving the effect of slowing down the air flow. If the flow velocity sensor 6 detects that the flow velocity is V1, the solenoid valve 7 controls the counter jet head 403 and the vertical jet head 8 to open, so that the counter jet head 403 and the vertical jet head 8 cooperate with each other to slow down the air flow velocity flowing into the upper air outlet structure 201, so as to achieve the purpose of reducing the flow velocity for better sedimentation.

[0033] like Figure 1 and Figure 8As shown, the dust-raising airflow in the three-way tank body 1 can be atomized and settled by the atomizing mechanism 5 .

[0034] Specifically, the atomizing mechanism 5 comprises a liquid storage container 501, a delivery pipe 502, an upper spray head 503 and a lower spray head. The upper spray head 503 is mounted on the three-way tank body 1, and the lower spray head is mounted on the dividing plate 401. The spray direction of the upper spray head 503 is aimed at the area where the dust airflow passes through the upper air outlet structure 201, and the spray direction of the lower spray head is aimed at the collision area formed by the jet head 403 and the upper air outlet structure 201. Since the upper spray head 503 and the lower spray head have different directions, the airflow can be atomized during the process of being transported in, and the upper spray head 503 can atomize the collision area again, thereby improving the atomization effect and achieving the effect of atomization sedimentation. The liquid storage container 501 is connected with the upper spray head 503 and the lower spray head through the delivery pipe 502, so that the upper spray head 503 and the lower spray head spray the liquid in the liquid storage container 501. A clean water area 12 is provided in the liquid storage container 501.

[0035] The clean water area 12 is provided with an injection port; the clean water area 12 is connected to a discharge assembly 14, which in this embodiment is composed of a water outlet pipe and a water pump, through which water can be pumped out, and the discharge assembly 14 is connected to the delivery pipe 502; the flow rate sensor 6 is controlled and connected to the two discharge assemblies 14, and the flow rate sensor 6 controls the start of the discharge assembly 14, so that the clean water in the liquid storage tank 501 can be pumped to the upper sprinkler head 503 and the lower sprinkler head.

[0036] Embodiment 2, in the structure of embodiment 1, when the airflow flowing into the upper air outlet structure 201 is too large, the adsorption of clean water is weak, resulting in the inability to adsorb dust particles well, causing the dust particles to rotate in the three-way tank body 1, and even when squeezed too much, they will be discharged through the exhaust port 3, resulting in poor sedimentation effect.

[0037] Based on the above problems, this embodiment Figure 3 As shown, a flow rate sensor 6 is installed on the upper air outlet structure 201, and the flow rate sensor 6 is respectively controlled and connected with the hedging mechanism 4 and the atomizing mechanism 5.

[0038] Specifically, the liquid storage container 501 is fixedly arranged on the left side of the three-way tank body 1, and a fixed plate 11 is fixedly arranged inside the liquid storage container 501. The fixed plate 11 divides the liquid storage container 501 into a clear water area 12 and a foam area 13 from top to bottom. The clear water area 12 and the foam area 13 are stored separately by the fixed plate 11 to facilitate use in different stages, and both the clear water area 12 and the foam area 13 can be provided with injection ports; the clear water area 12 and the foam area 13 are respectively connected to the discharge assembly 14. In this embodiment, the discharge assembly 14 is composed of a water outlet pipe and a water pump, and water can be pumped out by the water pump. The two discharge assemblies 14 are connected to the delivery pipe 502; the flow rate sensor 6 is controllably connected to the two discharge assemblies 14.

[0039] In this embodiment, the air flow velocity of the upper air outlet structure 201 is V1>V2>V3. When the flow velocity sensor 6 detects that the flow velocity of the dust airflow is V3, the water pump on the clean water area 12 is used to pump clean water to the upper spray head 503 and the lower spray head, so that the clean water is sprayed out to adsorb and settle the dust particles. When the flow velocity sensor 6 detects that the flow velocity is V2, the water pump on the clean water area 12 is closed by the solenoid valve 7, and the water pump on the foam area 13 is turned on, so that the water pump on the foam area 13 pumps the foam to the upper spray head 503 and the lower spray head, thereby increasing the adsorption capacity of the atomized particles and improving the atomization and sedimentation effect. If the flow velocity sensor 6 detects that the flow velocity is V1, the water pump on the clean water area 12 and the water pump on the foam area 13 are both started, so that the clean water and foam are mixed and pumped to the upper spray head 503 and the lower spray head, so that the dust particles are adsorbed to achieve better sedimentation.

[0040] Compared with Example 1, the advantage of this embodiment is that when the flow speed of the dust-raising airflow of the upper air outlet structure 201 is different, it is possible to spray atomized particles with different adsorption capacities, so as to achieve the purpose of improving the atomization effect.

[0041] Embodiment 3: In the structures of Embodiment 1 and Embodiment 2, the upper spray head 503 and the lower spray head cannot be adjusted, so that the spraying position, direction and range of the upper spray head 503 and the lower spray head cannot be adjusted according to demand, resulting in poor atomization effect.

[0042] Based on the above problems, this embodiment Figure 6 and Figure 7As shown, the interior of the three-way tank body 1 is provided with two chambers 15 spaced up and down, a sliding limit groove is opened on the inner bottom wall of the three-way tank body 1, the ski limit groove is connected with the chamber 15, the adjustment mechanism 19 moves along the sliding limit groove, each chamber 15 is slidably provided with an arc-shaped rack 16, and the arc-shaped rack 16 extends along the extension direction of the chamber 15. Two first driving devices 17 are fixedly provided on the three-way tank body 1. In this embodiment, the first driving device 17 is a first driving self-locking motor, and the output end of each first driving device 17 is transmission-connected with a gear 18, and the gear 18 is connected to the arc-shaped rack 16. The arc-shaped racks 16 mesh with each other, so that the arc-shaped racks 16 move along the chamber 15; an adjustment mechanism 19 is fixedly provided at one end of each arc-shaped rack 16 away from the gear 18. When the arc-shaped rack 16 moves, it can drive the adjustment mechanism 19 to move.

Since the gear 18 is meshed with the arc-shaped rack 16, the arc-shaped rack 16 can be driven to slide along the chamber 15.

[0043] The adjustment mechanism 19 includes a fixed frame 1901, a flip frame 1902 and a bevel gear set 1903; the fixed frame 1901 is fixedly arranged on the arc-shaped rack 16, and the upper spray head 503 or the lower spray head is rotatably arranged on the flip frame 1902. A flip driving mechanism 20 is arranged on one side of the fixed frame 1901. After the flip driving mechanism 20 is started, it can drive the flip frame 1902 to rotate, so as to drive the upper spray head 503 or the lower spray head to flip, so as to adjust the swing angle of the upper spray head 503 or the lower spray head. A self-rotation driving mechanism is arranged on the other side of the fixed frame 1901. 21, the flip frame 1902 is connected with the flip driving mechanism 20 and the rotation driving mechanism 21, so that the upper spray head 503 or the lower spray head flips around the flip driving mechanism 20; the rotation driving mechanism 21 is connected with the upper spray head 503 or the lower spray head through the bevel gear set 1903, so that the upper spray head 503 or the lower spray head rotates. After the rotation driving mechanism 21 is started, it can drive the bevel gear set 1903 to rotate, so that the bevel gear set 1903 drives the upper spray head 503 or the lower spray head to rotate, so as to adjust the spraying direction of the upper spray head 503 or the lower spray head.

[0044] In this embodiment, Fig. 9 As shown, the upper spray head 503 or the lower spray head is a spray head with a spray range that can be adjusted, and the upper spray head 503 or the lower spray head is long, and the spray range can be adjusted when the upper spray head 503 or the lower spray head rotates.
