Description

Technical Field

[0001] This utility model relates to an activated carbon adsorption device for forging workshops, used to adsorb waste gas in forging workshops, and belongs to the technical field of air purification equipment. Background Technology

[0002] Forging workshops typically generate waste gases such as high-temperature molten slag, dust, and harmful gases during production. Activated carbon adsorption boxes, as a highly efficient and economical air purification device, are commonly used for waste gas treatment in forging workshops. An activated carbon adsorption box usually consists of an outer shell, activated carbon, and a fan. The activated carbon is used to adsorb the high-temperature molten slag, dust, and harmful gases in the waste gas. The outer shell is a hollow cylinder with an inlet pipe and an outlet pipe at each end. Activated carbon is placed between the inlet and outlet pipes, serving as a medium connecting them. A fan located at the outlet pipe draws the waste gas into the activated carbon adsorption box from the inlet pipe. After purification by the activated carbon, the waste gas is discharged from the activated carbon adsorption box through the outlet pipe.

[0003] Before the activated carbon in the activated carbon adsorption box reaches adsorption saturation, it needs to be replaced with new activated carbon; otherwise, its adsorption capacity will decrease, and it will lose its air purification effect. However, existing activated carbon adsorption boxes require shutdown for activated carbon replacement, which seriously affects purification efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an activated carbon adsorption device for forging workshops, so as to solve the problem that the activated carbon adsorption box in the prior art needs to be shut down when changing the activated carbon.

A second sliding plate for closing or opening the connection between the second filter channel and the air extraction channel is provided on the outer shell along the vertical direction.

[0007] During the up-and-down sliding process, the first sliding plate has a carbon-changing station that moves to the bottom wall of the outer shell to close the carbon-changing station between the first filter channel and the exhaust channel. During the up-and-down sliding process, the first sliding plate also has a purification station that moves away from the bottom wall of the outer shell to open the purification station between the first filter channel and the exhaust channel. A limiting part is provided between the first sliding plate and the outer shell to limit the first sliding plate when it moves to the carbon-changing station and the purification station, respectively.

A limiting part is provided between the second sliding plate and the outer shell to limit the second sliding plate when it moves to the carbon-changing station and the purification station, respectively.

[0008] A fixed plate is provided on the outer shell between the first sliding plate and the second sliding plate. Two sliders are slidably arranged on the fixed plate from left to right. The sliders are driven by a linear drive mechanism. On the side of the first sliding plate and the second sliding plate, a maintenance groove and a purification groove are respectively opened on the side near the fixed plate, which cooperate with the sliders. The sliders, the maintenance groove and the purification groove respectively form different limiting parts.

[0009] Both the first and second air passages have baffles at their front ends, and the exhaust passage has a tail plate at its rear end. The front and rear walls of the first and second sliding plates are each provided with a sliding strip.

[0029] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only a part of the embodiments of this utility model, and not all of them. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Specific embodiments of the activated carbon adsorption device for forging workshops involved in this utility model are described below. Figures 1-10The device has a cylindrical outer shell 1. An inlet pipe 2 and an outlet pipe 3 are respectively installed at the front and rear ends of the outer shell 1. The inlet pipe 2 is used to draw in the exhaust gas to be purified from the forging workshop, and the outlet pipe 3 is used to discharge the purified exhaust gas. An exhaust channel 4 extending in the front-rear direction and connected to the inlet pipe 2 is provided inside the outer shell 1. A first filter channel 5 and a second filter channel 6, communicating with the exhaust channel 4, are provided on the left and right sides of the exhaust channel 4 inside the outer shell 1. Replaceable activated carbon 7 is installed in the first filter channel 5 and the second filter channel 6. The activated carbon 7 is used to adsorb high-temperature slag, dust, and harmful gases in the exhaust gas, thereby purifying the exhaust gas generated in the forging workshop. A first air passage 8, connecting the first filter channel 5 and the outlet pipe 3, is provided on the left side of the first filter channel 5 inside the outer shell 1. A second air passage 9 is provided on the right side of the second filter channel 6, connecting the second filter channel 6 and the air outlet pipe 3. A first carbon extraction port 10 is provided on the upper end of the outer shell 1 above the first filter channel 5. A first carbon extraction door 11 that can be opened and closed is provided at the first carbon extraction port 10. A second carbon extraction port 12 is provided on the upper side of the second filter channel 6 on the outer shell 1. A second carbon extraction door 13 that can be opened and closed is provided at the second carbon extraction port 12. Both the first carbon extraction port 10 and the second carbon extraction port 12 are used to take out or put in activated carbon 7 when needed. A first sliding plate 14 for closing or opening the space between the first filter channel 5 and the air extraction channel 4 is provided on the outer shell 1 along the vertical direction. A second sliding plate 15 for closing or opening the space between the second filter channel 6 and the air extraction channel 4 is provided on the outer shell 1 along the vertical direction. The first sliding plate 14 and the second sliding plate 15 are both slidably assembled in the outer shell 1. The first sliding plate 14 and the second sliding plate 15 are symmetrically arranged. The second sliding plate 15 has the same structure as the first sliding plate 14. A sliding hole is provided on the top wall of the outer shell 1. The top of both sliding plates passes through the sliding hole and extends out of the outer shell 1. A lifting hole is provided on both sliding plates, which can be used to lift or lower them.

[0032] Specifically, during the up-and-down sliding process, the first sliding plate 14 has a carbon-changing station that moves to the bottom wall of the outer shell 1 to close the carbon-changing station between the first filter channel 5 and the exhaust channel 4. During the up-and-down sliding process, the first sliding plate 14 also has a purification station that moves away from the bottom wall of the outer shell 1 to open the carbon-changing station between the first filter channel 5 and the exhaust channel 4. A limiting part is provided between the first sliding plate 14 and the outer shell 1 to limit the first sliding plate 14 when it moves to the carbon-changing station and the purification station, respectively. During the up-and-down sliding process, the second sliding plate 15 has a carbon-changing station that moves to the bottom wall of the outer shell 1 to close the carbon-changing station between the second filter channel 6 and the exhaust channel 4. During the up-and-down sliding process, the second sliding plate 15 also has a purification station that moves away from the bottom wall of the outer shell 1 to open the carbon-changing station between the second filter channel 6 and the exhaust channel 4. A limiting part is provided between the second sliding plate 15 and the outer shell 1 to limit the second sliding plate 15 when it moves to the carbon-changing station and the purification station, respectively.

[0033] Application scenario 1 of this utility model: The first filter channel 5 and the second filter channel 6 operate synchronously. In use, the limiting part restricts both the first sliding plate 14 and the second sliding plate 15 to the purification station. Then, the waste gas to be purified from the forging workshop is drawn into the extraction channel 4 through the inlet pipe 2, and then divided into two purification paths. In each purification path, the waste gas is adsorbed and purified by an activated carbon 7 before entering the corresponding first exhaust channel 8 or second exhaust channel 9, and finally discharged through the outlet pipe 3. When the original activated carbon 7 is close to adsorption saturation, in order to prevent the activated carbon 7 on both sides from reaching saturation simultaneously, it needs to be replaced before both activated carbon 7 become saturated. Here, we take replacing the activated carbon 7 in the first filter channel 5 as an example. First, release the limiting part from restricting the first sliding plate 14, slide the first sliding plate 14 downwards, and move the first sliding plate 14 to... At the carbon replacement station, the limiting part restricts the first sliding plate 14 to the carbon replacement station. At this time, the first sliding plate 14 separates the activated carbon 7 from the exhaust channel 4, and the exhaust gas in the exhaust channel 4 is blocked by the first sliding plate 14. This purification path is blocked by the first sliding plate 14, but the other purification path is operating normally. Then, the first carbon removal door 11 can be opened to take out the activated carbon 7 that needs to be replaced through the first carbon removal port 10 and put in the new activated carbon 7. Then, the first carbon removal door 11 is closed, and the limiting part restricts the first sliding plate 14. The first sliding plate 14 is slid upward to move the first sliding plate 14 to the purification station. Then, the limiting part restricts the first sliding plate 14 to the purification station, and this purification path is restored. At this time, both purification paths are operating normally. Then, the activated carbon 7 in the second filter channel 6 is replaced in the same way.

[0034] Application scenario two of this utility model: one filtration channel is operated at a time. Here, we take the operation of the first filtration channel 5 as an example. In use, the first sliding plate 14 is restricted to the purification station by the limiting part, and the second sliding plate 15 is restricted to the carbon replacement station. Then, the exhaust gas to be purified from the forging workshop is drawn into the exhaust channel 4 through the air inlet pipe 2. After being adsorbed and purified by the activated carbon 7 in the first filtration channel 5, the exhaust gas enters the first exhaust channel 8 and is finally discharged through the exhaust pipe 3. When the activated carbon 7 in the first filter channel 5 is close to adsorption saturation, the restriction of the limiting part on the second sliding plate 15 is first released, and the second sliding plate 15 is slid upward, moving to the purification station. Then, the limiting part restricts the second sliding plate 15 to the purification station, at which point the purification path of the second filter channel 6 begins to operate. Next, the restriction of the limiting part on the first sliding plate 14 is released, and the first sliding plate 14 is slid downward, moving to the carbon replacement station. Then, the limiting part restricts the first sliding plate 14 to the carbon replacement station, at which point the first sliding plate 14 connects the activated carbon 7 with the air extraction channel. The exhaust gas in the extraction channel 4 is blocked by the first sliding plate 14, thus blocking this purification path. However, the other purification path continues to operate normally. Then, the first carbon extraction door 11 can be opened to remove the activated carbon 7 that needs to be replaced through the first carbon extraction port 10 and a new activated carbon 7 can be placed in. Then, the first carbon extraction door 11 is closed. At this time, the purification path where the first filter channel 5 is located is in a stopped state. When the activated carbon in the second filter channel 6 is close to adsorption saturation, the activated carbon 7 in the second filter channel 6 is replaced in the same way. This cycle is repeated to replace the activated carbon without stopping the machine.

[0035] Specifically, a fixed plate 16 is provided on the outer shell 1 between the first sliding plate 14 and the second sliding plate 15. Two sliders 17 are slidably arranged on the fixed plate 16. The sliders 17 are driven by a linear drive mechanism, which is a cylinder 18. The cylinder body of the cylinder 18 is fixed on the fixed plate 16, and the piston rod of the cylinder 18 is fixed on the sliders 17. The first sliding plate 14 and the second sliding plate 15 are respectively provided with a maintenance groove 19 and a purification groove 20 that cooperate with the sliders 17 on the side near the fixed plate 16. The sliders 17, the maintenance groove 19 and the purification groove 20 respectively constitute different limiting parts. Slide slider 17 away from the first sliding plate 14 or the second sliding plate 15 using cylinder 18, so that the first sliding plate 14 or the second sliding plate 15 is slid into the maintenance slot 19 and aligned with slider 17. Then, drive slider 17 to reset using cylinder 18, so that slider 17 can be locked into the maintenance slot 19, thereby restricting the first sliding plate 14 or the second sliding plate 15 to the carbon changing station. Slide slider 17 away from the first sliding plate 14 or the second sliding plate 15 using cylinder 18, so that the first sliding plate 14 or the second sliding plate 15 is slid into the purification slot 20 and aligned with slider 17. Then, drive slider 17 to reset using cylinder 18, so that slider 17 can be locked into the purification slot 20, thereby restricting the first sliding plate 14 or the second sliding plate 15 to the purification station.

[0036] Specifically, both the first air passage 8 and the second air passage 9 are equipped with partitions 21 at their front ends, and the exhaust passage 4 is equipped with a tail plate 22 at its rear end. Sliding strips 23 protrude from the front and rear walls of the first sliding plate 14 and the second sliding plate 15. Sliding grooves 24 are respectively formed on the partitions 21 and the tail plate 22, and the sliding strips 23 slide in conjunction with the sliding grooves 24. When the first sliding plate 14 or the second sliding plate 15 slides up and down, the sliding strips 23 slide in the sliding grooves 24, enabling the first sliding plate 14 or the second sliding plate 15 to slide more smoothly and preventing it from tilting left or right during sliding. When the first sliding plate 14 or the second sliding plate 15 is confined to the purification station, the sliding strips 23 are engaged in the sliding grooves 24, further isolating the exhaust gas and preventing it from escaping between the front end of the first sliding plate 14 or the partition 21 and between the rear end of the first sliding plate 14 or the tail plate 22.

[0037] Specifically, both the first sliding plate 14 and the second sliding plate 15 have protruding strips 25 on their bottom walls, and the bottom wall of the outer casing 1 has grooves 26 that cooperate with the protruding strips 25. When the first sliding plate 14 or the second sliding plate 15 is confined in the carbon changing station, the protruding strips 25 are engaged in the grooves 26, which can further isolate the exhaust gas and prevent the exhaust gas from escaping between the lower end face of the first sliding plate 14 or the second sliding plate 15 and the bottom wall of the outer casing 1.

[0038] Specifically, a first exhaust fan 27 is installed in the exhaust pipe 3, and the first exhaust fan 27 is driven to rotate by a power mechanism. The power mechanism is a motor 28, the main body of which is fixed on the exhaust pipe 3, and the rotor of which is fixed on the shaft of the first exhaust fan 27. The first exhaust fan 27 is used to extract the gas in the outer casing 1, thereby creating a negative pressure in the outer casing 1, and then drawing the waste gas to be purified into the outer casing 1 from the intake pipe 2.

[0039] Specifically, a second exhaust fan 29 is installed between the exhaust channel 4 and the intake pipe 2. A connecting rod 30 is fixedly installed on the shaft of the second exhaust fan 29. The connecting rod 30 rotates through the through hole on the tail plate 22 and is fixed on the shaft of the first exhaust fan 27. When the motor 28 drives the first exhaust fan 27 to rotate, the second exhaust fan 29 rotates synchronously. The second exhaust fan 29 and the first exhaust fan 27 work together to improve the efficiency of exhaust gas intake.

[0040] Specifically, an exhaust pipe 31 extends from the exhaust pipe 3. The exhaust pipe 31 is used to discharge the purified gas from the exhaust pipe 3.

[0041] Specifically, a filter screen 32 is also provided in the outer casing 1, and the filter screen 32 is located between the air intake pipe 2 and the second exhaust fan 29. The filter screen 32 is used to initially filter the exhaust gas drawn into the outer casing 1 to filter out large particulate solids in the exhaust gas.

[0042] Specifically, protective nets 33 are installed on both sides of the activated carbon 7 in both the first filter channel 5 and the second filter channel 6. The protective nets 33 are used to protect the activated carbon 7, prevent the activated carbon 7 from tipping over or shifting during the purification of waste gas, and the protective nets 33 do not obstruct the flow of waste gas.

[0043] In the above embodiment, a fixed plate is provided on the outer shell between the first sliding plate and the second sliding plate. Two sliders are slidably arranged on the fixed plate from left to right. This is an optimized technical solution. In other embodiments, the fixed plate may not be provided. Instead, two sliders are directly slidably arranged on the top wall of the outer shell from left to right.

[0044] In the above embodiment, the front and rear walls of the sliding plate are provided with sliding strips, and the partition and tail plate are respectively provided with sliding grooves. The sliding strips and sliding grooves are correspondingly arranged. This is an optimized technical solution. In other embodiments, the sliding strips and sliding grooves may not be provided.

[0045] In the above embodiment, a protruding strip is provided on the bottom wall of the sliding plate, and a groove corresponding to the protruding strip is provided on the bottom wall of the outer shell. This is an optimized technical solution. In other embodiments, the protruding strip and groove may not be provided.

[0046] In the above embodiment, a first exhaust fan is provided in the exhaust pipe, which is an optimized technical solution. In other embodiments, the first exhaust fan may not be provided, and an exhaust fan may be connected to the rear end of the exhaust pipe.
