Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in forging workshops, specifically a dust collector for forging workshops. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing plastic deformation to obtain forgings with certain mechanical properties, shapes, and sizes. Dust is generated during the processing, and the dust emitted into the air can cause air pollution. Therefore, most forging workshops need to be equipped with dust collectors.

[0003] Existing dust removal equipment sucks up dust during use. When dust is sucked into the device, it is stirred up inside, causing the device to become filled with dust and potentially damaging it.

[0004] Chinese utility model patent CN209501212U discloses a dust collector for forging workshops. Although this dust collector can combine dust with water through the cooperation of a water pump and a vertical pipe to prevent dust inside the device from being stirred up and clogging the dust collection device, it requires the addition of additional water pumping equipment, which will increase costs. Moreover, the continuous operation of the water pump to spray water mist will increase energy consumption. Utility Model Content

[0005] (a) Technical problems to be solved In view of the shortcomings of the prior art, this utility model provides a dust collector for forging workshops, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: It includes a dust collection bin, with a suction port connected to a suction pipe. An air outlet is located on the top surface of the dust collection bin. A motor is fixedly connected to the top surface of the dust collection bin. One end of the motor's output shaft passes through the dust collection bin and is fixedly connected to a rotating shaft. A fan is fixedly connected to one end of the rotating shaft. A transmission assembly is fixedly connected to the outer surface of the rotating shaft. An arc-shaped box is located on the outer surface of the dust collection bin. A partition divides the arc-shaped box into an upper chamber and a lower chamber. A piston assembly is slidably fitted into the upper chamber. The piston assembly includes a piston and a piston rod. The piston assembly contacts the transmission assembly, which drives the piston to reciprocate. The upper chamber has an air outlet on one side of the rodless chamber, and the lower chamber has a water outlet, an air inlet, and a water inlet. The lower chamber, water outlet, and water inlet together with the arc-shaped box form a water tank. The air inlet of the lower chamber is located at the top of the lower chamber. The air outlet of the upper chamber is connected to the air inlet of the lower chamber. The water inlet of the lower chamber is located on the side of the lower chamber away from the outer wall of the dust collection bucket. The water inlet of the lower chamber has a one-way valve inside that leads to the lower chamber. The water outlet of the lower chamber is connected to a water outlet pipe and is located at the bottom of the lower chamber. The front end of the water outlet pipe extends into the dust collection bucket and is connected to an atomizing nozzle. The spray range of the atomizing nozzle covers the airflow of the dust collection, causing the dust in the dust-laden airflow to settle.

[0007] Optionally, the water outlet of the water pipe is higher than the height of the water tank in the arc-shaped container, and the water outlet of the lower chamber is close to the outer wall of the dust collection bucket.

[0008] Optionally, the transmission assembly includes an eccentric wheel, which is fixedly connected to the rotating shaft. One end of the piston rod is spherical and extends into the dustbin, contacting the edge of the eccentric wheel.

[0009] Optionally, there are two arc-shaped boxes, which are symmetrically and fixedly connected to the outer surface of the dust collection bin.

[0010] Optionally, a filter screen is fixedly connected to the middle of the inner surface of the dust collection bin, and the atomizing nozzle is positioned between the filter screen and the fan.

[0011] This utility model provides a dust collector for forging workshops, which has the following beneficial effects: 1. The dust collector used in this forging workshop, when it is necessary to treat the dust raised inside the dust collection bin, is designed with a motor and a rotating shaft working together to drive the fan and transmission components to rotate. The dust collection pipe, connected to the air outlet, can collect the dust in the forging workshop. Simultaneously, the transmission components compress the piston, causing it to slide on the surface of the partition. Because the air outlet of the upper chamber is connected to the air inlet of the lower chamber, air from the piston's rodless side is forced into the lower chamber of the partition. Since the space in the lower chamber of the partition is constant, and the one-way valve allows only inflow, the pressure in the lower chamber is increased. This forces water from the lower chamber out through the water outlet and atomizing nozzle. The sprayed water mist combines with the dust, preventing it from being raised inside the dust collection bin. The motor-driven fan collects dust, and the atomizing nozzle sprays water mist to treat the raised dust, reducing both cost and energy consumption. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0015] Please see Figures 1 to 5The present invention provides a technical solution including a dust collection bin 6, a dust collection pipe 2 connected to the dust collection port of the dust collection bin 6, an air outlet 21 provided on the top surface of the dust collection bin 6, a motor 5 fixedly connected to the top surface of the dust collection bin 6, one end of the output shaft of the motor 5 passing through the dust collection bin 6 and fixedly connected to a rotating shaft 10, one end of the rotating shaft 10 fixedly connected to a fan 8, a transmission assembly 25 fixedly connected to the outer surface of the rotating shaft 10, and an arc-shaped box 3 provided on the outer surface of the dust collection bin 6. There are two arc-shaped boxes 3, which are symmetrically fixedly connected to the outer surface of the dust collection bin 6. The interior of the arc-shaped box 3 is provided with... A partition 17 divides the arc-shaped box 3 into an upper chamber 23 and a lower chamber 24. A piston assembly 19 is slidably fitted into the upper chamber 23. The piston assembly 19 includes a piston 15 and a piston rod 14. The piston assembly 19 contacts a transmission assembly 25, which drives the piston 15 to reciprocate linearly. An air outlet is located on one side of the rodless chamber of the upper chamber 23. The lower chamber 24 has a water outlet, an air inlet, and a water inlet. The lower chamber 24, the water outlet, and the water inlet, together with the arc-shaped box 3, form a water tank. The air inlet of the lower chamber 24 is located at the top of the lower chamber 24. The upper chamber 23... The air outlet of the upper chamber 23 is connected to the air inlet of the lower chamber 24. A through hole 18 is provided at the top of the partition 17, located on one side of the rodless chamber of the upper chamber 23. The through hole 18 connects the upper chamber 23 to the lower chamber 24. The water inlet of the lower chamber 24 is located on the side of the lower chamber 24 away from the outer wall of the dustbin 6. A water inlet pipe 4 is connected to the water inlet of the lower chamber 24. When there is no water in the lower chamber 24, water is replenished to the lower chamber 24 by connecting it to an external faucet through the water inlet pipe 4. A one-way valve leading to the lower chamber 24 is provided inside the water inlet of the lower chamber 24. The one-way valve includes a fixing block 22 fixedly connected to the inner surface of the water inlet pipe 4. A spring 26 is fixedly connected to one end of the fixing block 22, and a sealing plate 20 is fixedly connected to one end of the spring 26. The sealing plate 20 is circular in shape and fits against the water inlet of the lower chamber 24. The water outlet of the lower chamber 24 is connected to the water outlet pipe 12. The water outlet of the lower chamber 24 is located at the bottom of the lower chamber 24. The front end of the water outlet pipe 12 extends into the dust collection bucket 6 and is connected to the atomizing nozzle 13. The spraying range of the atomizing nozzle 13 covers the airflow of the dust collection, so that the dust in the dust-laden airflow settles.

[0016] Specifically, when it is necessary to treat the dust stirred up inside the dust collection bin 6, the motor 5 and the rotating shaft 10 work together to drive the fan 8 and the transmission assembly 25 to rotate. Through the cooperation of the suction pipe 2 and the air outlet 21, the dust in the forging workshop can be treated via the suction pipe 2. At this time, the transmission assembly 25 compresses the piston 15 to slide on the surface of the partition 17. Because the air outlet of the upper chamber 23 is connected to the air inlet of the lower chamber 24, air on one side of the piston 15 can be forced through the through hole 18 into the lower part of the partition 17, entering the lower... The air compression sealing plate 20 of the chamber 24 fits against the water inlet of the lower chamber 24 to prevent air from leaking from the water pipe 4. Since the space below the partition 17 is constant, the pressure below the partition 17 can be increased, which can force the water below the partition 17 out through the water outlet pipe 12 and the atomizing nozzle 13. The sprayed water mist combines with the dust, preventing the dust from being stirred up inside the dust collection bin 6. The motor 5 drives the fan 8 to perform dust collection and drives the atomizing nozzle 13 to spray water mist to treat the stirred-up dust. This not only reduces costs but also reduces energy consumption.

[0017] Please see Figures 1 to 3 The water outlet of the water pipe 12 is higher than the water level of the arc-shaped box 3, and the water outlet of the lower chamber 24 is close to the outer wall of the dust collection bucket 6.

[0018] Specifically, since the outlet height of the water outlet pipe 12 is higher than the height of the water in the arc-shaped box 3, the water in the arc-shaped box 3 can be prevented from flowing out due to gravity.

[0019] Please see Figure 2 As shown in Figure 3, the transmission assembly 25 includes an eccentric wheel 9, which is fixedly connected to the rotating shaft 10. One end of the piston rod 14 is spherical and extends into the dust collection bin 6 and contacts the edge of the eccentric wheel 9. An elastic telescopic rod 16 is provided on one side of the piston 15, and the two ends of the elastic telescopic rod 16 are fixedly connected to one side surface of the piston 15 and the inner surface of the arc-shaped box 3, respectively. Specifically, when the eccentric wheel 9 disengages from the piston rod 14, the elasticity of the elastic telescopic rod 16 allows the piston 15 to return to its original position. Simultaneously, due to the superposition of a suction force generated inside the arc-shaped box 3 and the atmospheric pressure outside the arc-shaped box 3, and with the cooperation of the spring 26, the sealing plate 20 disengages from the water inlet of the lower chamber 24, allowing external air to be drawn into the arc-shaped box 3. This facilitates the next compression of the air in the rodless side of the upper chamber 23 by the piston 15, enabling continuous water spraying. As the pressure in the lower chamber 24 decreases due to the partition 17, the height of the water outlet of the water outlet pipe 12 is higher than the height of the water in the arc-shaped box 3. Furthermore, due to the gravity of the water, it flows back from the water outlet pipe 12 into the arc-shaped box 3, allowing the atomizing nozzle 13 to stop spraying water.

[0020] Please see Figure 2The bottom of the dust collection bin 6 is fixedly connected to a dust collection bin 11. The top of the dust collection bin 11 has a dust inlet. A filter screen 7 is fixedly connected to the middle of the inner surface of the dust collection bin 6. The atomizing nozzle 13 is located between the filter screen 7 and the fan 8. The dust inlet of the suction pipe 2 is connected to the dust collection bin 11. A mobile cart 1 is fixedly connected to the bottom surface of the dust collection bin 6.

[0021] Specifically, the filter screen 7 filters the dust and large particles sucked into the dust collection bin 6, and the water sprayed by the atomizing nozzle 13 can clean the filter screen 7 to prevent dust from clogging it. The dust and the water used to clean the dust are collected in the dust collection bin 11.

[0022] During use, when it is necessary to deal with the dust stirred up inside the dust collection bin 6, the motor 5 and the rotating shaft 10 work together to drive the fan 8 and the transmission assembly 25 to rotate. The suction pipe 2 works with the air outlet 21 to remove dust from the forging workshop. At this time, the transmission assembly 25 compresses the piston 15, causing it to slide on the surface of the partition 17. Because the air outlet of the upper chamber 23 is connected to the air inlet of the lower chamber 24, air from one side of the piston 15 can be forced through the through hole 18 into the lower part of the partition 17. The air entering the lower chamber 24 compresses the sealing plate 20 to fit against the water inlet of the lower chamber 24, preventing air leakage from the water pipe 4. Since the space below the partition 17 is constant, the pressure below the partition 17 can be increased, forcing the water below the partition 17 out through the water outlet 12 and the atomizing nozzle 13. The sprayed mist combines with the dust, preventing dust from being stirred up inside the dust collection bin 6. When the eccentric wheel 9 disengages... When piston rod 14 is in motion, the elasticity of elastic telescopic rod 16 allows piston 15 to return to its original position. Simultaneously, as piston 15 returns to its original position, the suction force generated inside arc-shaped box 3, combined with the atmospheric pressure outside arc-shaped box 3, causes sealing plate 20 to disengage from the water inlet of lower chamber 24 through the cooperation of spring 26. This allows external air to be drawn into arc-shaped box 3, facilitating piston 15 on the lower side to compress the air in the rodless side of upper chamber 23, thus enabling continuous water spraying. Due to the reduced pressure below partition 17, the height of water outlet 12 is higher than the height of water in arc-shaped box 3. Furthermore, due to gravity, the water flows back from water outlet 12 into arc-shaped box 3, allowing atomizing nozzle 13 to stop spraying water. The filter screen 7 filters dust and large particles sucked into dust collection bin 6, and the water sprayed by atomizing nozzle 13 cleans the filter screen 7, preventing dust from clogging it. The dust and the water used for cleaning are collected in dust collection bin 11.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
