Description

Technical Field

[0001] This utility model relates to the field of air purifier regeneration technology, specifically an offline regeneration device for forklift air purifiers. Background Technology

[0002] The DPF (Diverterless Power Filter) works by using a combination of surface and internal filtration devices, such as diffusion sedimentation, inertial sedimentation, and linear interception, to capture particles, effectively purifying 70% to 90% of particulate matter in exhaust gas. When engine exhaust enters the DPF, the tiny particles are captured and accumulate. Over time, these accumulated particles gradually increase, and if they exceed a certain limit, regeneration is necessary. During regeneration, the exhaust temperature is increased, converting the accumulated particles into carbon dioxide and water vapor, thus cleaning the filter.

[0003] Forklifts are typically equipped with DPF (Diesel Particulate Filter) systems to effectively purify exhaust gases. However, over time, particulate matter gradually accumulates inside the DPF, eventually causing blockages. Users must close the valve on the engine's exhaust port and then open the valve on the intake manifold. Next, the fan and heater need to be activated to allow hot air to flow into the DPF. The hot air heats the carbon particles accumulated in the filter, converting them into carbon dioxide and water vapor, thus clearing the blockage. This cleaning process is relatively complex and requires careful following of the steps. Furthermore, the lack of a clear instruction system to inform users when the DPF needs cleaning makes it difficult to know in advance when this maintenance is required, making the cleaning process inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide an offline regeneration device for purifiers used in forklifts, so as to solve the problem of inconvenient cleaning of purifiers in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an offline regeneration device for a forklift purifier, comprising a forklift purifier, a control mechanism connected to the air inlet of the forklift purifier, an air supply pipe connected to the control mechanism, a heater provided on the air supply pipe, a fan connected to the end of the air supply pipe, the control mechanism comprising a control assembly connected to the air inlet of the forklift purifier, a control block rotatably mounted inside the control assembly, the control block having a through port and a connecting port, the through port penetrating the control block, and the connecting port communicating with the through port, a drive mechanism fixedly mounted on the upper end of the control assembly.

[0006] Preferably, the communication port is provided with a filter screen, the control assembly is provided with a cleaning port, an air outlet, a first air inlet and a second air inlet, and the cleaning port is aligned with the first air inlet and the air outlet is aligned with the second air inlet. A pressure sensor is provided at the air outlet, and a plug is threaded into the cleaning port.

[0007] Preferably, a detection port is provided at the air outlet, and the air pressure sensor is installed at the air outlet through the detection port.

[0008] Preferably, the control assembly is connected to the forklift purifier via an air outlet, the air supply pipe is connected to the control assembly via a first air inlet, the control block is provided with a rotating shaft, the control block is rotatably installed in the control assembly via the rotating shaft, and sealing rings are installed at the upper and lower edges of the control block.

[0009] Preferably, the drive mechanism includes a housing fixedly mounted on the control assembly, a drive shaft rotatably mounted inside the housing, a worm gear fixedly mounted on the drive shaft, a motor fixedly mounted on the housing, and a worm gear fixedly mounted at the output end of the motor.

[0010] Preferably, the housing of the mechanism is provided with a bearing, the drive shaft is rotatably mounted on the housing of the mechanism through the bearing, and the lower end of the drive shaft is fixedly mounted on the rotating shaft of the control block.

[0011] Preferably, the worm wheel is rotatably mounted inside the housing of the mechanism via a drive shaft, and the worm is rotatably mounted inside the housing of the mechanism via a motor, with the worm and the worm wheel meshing together.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, when the pressure sensor detects a significant increase in the inlet pressure of the forklift purifier, it indicates a large amount of particulate matter accumulated inside the purifier, necessitating regeneration. A motor drives a worm gear to rotate, which in turn drives a worm wheel, subsequently rotating the drive shaft and ultimately the control block. The motor stops operating when the connecting port aligns with the outlet. Subsequently, the fan and heater start, and high-temperature air enters the forklift purifier through the connecting port. The high-temperature air converts the accumulated particulate matter into carbon dioxide and water vapor, thereby achieving rapid removal of the accumulated particulate matter inside the forklift purifier.

[0014] 2. In this application, after the motor starts, it drives the worm gear to rotate. Subsequently, the rotation of the worm gear drives the worm wheel, which in turn causes the drive shaft to rotate. The rotation of the drive shaft then causes the control block to rotate, facilitating automated control of the control mechanism and reducing the difficulty of cleaning. In addition, the motor has the function of reversing the worm gear, thereby resetting the connection port. Once the connection port is reset, the plug can be opened to allow the user to remove the filter screen for cleaning. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an offline regeneration device for a forklift purifier, including a forklift purifier 1. A control mechanism 5 is connected to the air inlet end of the forklift purifier 1. An air supply pipe 2 is connected to the control mechanism 5. A heater 3 is provided on the air supply pipe 2. A fan 4 is connected to the end of the air supply pipe 2. A drive mechanism 6 is fixedly installed on the upper end of the control assembly 501. Through the cooperation of the control mechanism 5 and the drive mechanism 6, the particulate matter accumulated in the forklift purifier 1 can be quickly removed.

[0022] like Figure 2 and Figure 3As shown, the control mechanism 5 includes a control assembly 501 connected to the air inlet of the forklift purifier 1. A control block 508 is rotatably installed inside the control assembly 501. The control block 508 has a through-hole 510 and a connecting port 507. The through-hole 510 passes through the control block 508, and the connecting port 507 is connected to the through-hole 510. A filter screen 503 is installed inside the connecting port 507. The control assembly 501 has a cleaning port 502, an air outlet 506, a first air inlet 509, and a second air inlet 511. The cleaning port 502 is aligned with the first air inlet 509, and the air outlet 506 is aligned with the second air inlet 511. A pressure sensor 505 is installed at the air outlet 506. A plug 504 is threaded into the cleaning port 502. A detection port is opened at the air outlet 506, and the pressure sensor 505 is installed at the air outlet 506 through the detection port.

[0023] Specifically, the air pressure sensor 505 can detect an abnormal increase in the inlet pressure of the forklift purifier 1, indicating that a large amount of particulate matter has accumulated inside the purifier. The operation of the motor 605 drives the worm gear 604 to rotate, which in turn causes the worm wheel 601 to rotate. The rotation of the worm wheel 601 is transmitted to the drive shaft 603, which in turn drives the control block 508 to rotate accordingly. When the connection port 507 on the control block 508 is fully aligned with the outlet port 506, the regeneration process inside the purifier can begin, and the operation of the motor 605 should be stopped at this time. Once the motor 605 stops working, the fan 4 and heater 3 can be started. The operation of the fan 4 introduces fresh air, and the heating effect of the heater 3 raises the temperature of the introduced air, creating high-temperature air. This high-temperature air enters the forklift purifier 1 through the connection port 507 and comes into contact with the accumulated particulate matter. Under high temperatures, particulate matter is effectively converted into carbon dioxide and water vapor, thereby cleaning the inside of the purifier and restoring its purification efficiency.

[0024] like Figure 2 and Figure 4 As shown, the drive mechanism 6 includes a mechanism housing 602 fixedly mounted on the control assembly 501. A drive shaft 603 is rotatably mounted inside the mechanism housing 602. A worm gear 601 is fixedly mounted on the drive shaft 603. A motor 605 is fixedly mounted on the mechanism housing 602. A worm gear 604 is fixedly mounted at the output end of the motor 605. A bearing is provided on the mechanism housing 602. The drive shaft 603 is rotatably mounted on the mechanism housing 602 through the bearing, and the lower end of the drive shaft 603 is fixedly mounted on the rotating shaft of the control block 508.

[0025] Specifically, when motor 605 is started, it begins to rotate worm gear 604. As worm gear 604 rotates, worm wheel 601 also rotates. The rotation of worm wheel 601 further drives the rotation of drive shaft 603. The rotation of drive shaft 603 causes control block 508 to rotate, facilitating automated control of control mechanism 5 and significantly reducing the difficulty of cleaning. Furthermore, motor 605 also has the ability to rotate worm gear 604 in the reverse direction, thus resetting the connection port 507. Once the connection port 507 is reset, the plug 504 can be easily opened. After opening the plug 504, the filter screen 503 can be easily removed for cleaning.

[0026] Working principle: During use, the exhaust pipe of the forklift engine is connected to the second air intake 511. The exhaust gas from the engine passes through the through-hole 510 and enters the forklift purifier 1, thereby purifying the exhaust gas. When the air pressure sensor 505 detects a large pressure at the air intake of the forklift purifier 1, it indicates that the accumulated particulate matter in the forklift purifier 1 is large and regeneration is required. At this time, the motor 605 drives the worm gear 604 to rotate. After the worm gear 604 rotates, it drives the worm wheel 601 to rotate. After the worm wheel 601 rotates, it drives the drive shaft 603 to rotate. After the drive shaft 603 rotates, it drives the control block 508 to rotate. When the connecting port 507 is aligned with the air outlet 506, the motor 605 stops. 5. After stopping motor 605, fan 4 and heater 3 can be started. After starting fan 4 and heater 3, high-temperature air will enter the forklift purifier 1 through the connecting port 507. The high-temperature air can convert the accumulated particulate matter into carbon dioxide and water vapor, thereby removing the accumulated particulate matter in the forklift purifier 1 and regenerating the forklift purifier 1. When the air pressure sensor 505 detects that the air pressure at the air inlet is normal, it means that the forklift purifier 1 has completed the regeneration process. At this time, motor 605 can be controlled to drive worm gear 604 to reverse, so that connecting port 507 is reset. After connecting port 507 is reset, plug 504 can be opened. After opening plug 504, filter screen 503 can be taken out for cleaning.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
