Description
A mobile intelligent industrial dust collector Technical Field
[0001] This utility model relates to the field of dust removal technology, specifically a mobile intelligent industrial dust collector. Background Technology
[0002] Industrial dust collectors are environmental protection devices used to capture, filter, and remove dust, fumes, particulate matter, and harmful gases generated during industrial production processes. They are widely used in metal processing, wood processing, chemical, pharmaceutical, food, and building materials industries. Common types include: Cyclone dust collectors: These use centrifugal force to separate large particles and are suitable for primary filtration.
[0003] Bag / cartridge dust collectors: efficiently filter fine dust and can handle high-temperature and high-humidity gases.
[0004] Wet scrubbers: They adsorb dust through water mist and are suitable for sticky dust or harmful gases (such as acid mist).
[0005] Electrostatic precipitators: High-voltage electric fields capture micron-sized particles; they have low energy consumption but high cost.
[0006] Among the aforementioned integrators, the most widely used is the bag filter integrator. Its bag substrate is made of non-woven needle-punched felt, and it operates with a footless device. However, the industrial dust collection equipment formed by this integrator has the following shortcomings:
[0007] With a fixed air volume and filtration area, the large size of the equipment cannot meet the current market demand for miniaturized equipment.
[0008] The unit filter area has a large number of filter bags, making maintenance troublesome. It requires timed pulse jet cleaning and cannot check the internal and external differential pressure.
[0009] The fixed location of the equipment results in poor mobility during use.
[0010] Therefore, in view of the above-mentioned problems, this technical solution proposes a mobile intelligent industrial dust collector. Summary of the Invention
[0011] The purpose of this invention is to provide a mobile intelligent industrial dust collector to solve the problems mentioned in the background art.
[0012] To achieve the above objectives, this utility model provides the following technical solution:
[0013] A mobile intelligent industrial dust collector includes a housing, a vertical fan, filter cartridges, a control box, and a moving assembly. The moving assembly is located at the bottom of the housing to improve its mobility. The housing is internally divided into a filtration chamber and a dust collection chamber. An air inlet is located on one side of the housing corresponding to the filtration chamber, and an air outlet is located on the top side of the filtration chamber. The filter cartridges are housed inside the filtration chamber and have a pleated structure (pleated filter cartridges have a larger filtration area, higher filtration efficiency, better air permeability, lower operating resistance, and greater durability compared to filter cartridges of the same area). The filter cartridges are used to trap dust in the passing dust-laden gas. The dust collection chamber is located below the filter cartridges and is used to trap dust from the upper part of the filter cartridges. The system collects the trapped dust (primarily using gravity to automatically drop the trapped dust). An air filtration system is integrated at the top of the housing, used to filter and regulate the pressure of the gas transmitted to the air tank. A vertical fan is installed inside the housing, connected to the air tank on one side. The air tank is directly connected to the air outlet. A control box with a built-in PLC control module is also installed on one side of the vertical fan. Based on the differential pressure gauge data, the control box triggers a pulse cleaning program, thus coordinating the operation of the vertical fan and the pulse jet cleaning of the air tank. The output end of the vertical fan is connected to the air outlet, and the inlet end is located on the upper side of the air tank, used to discharge the gas from the air tank outwards along the air outlet.
[0014] Compared with the prior art, the beneficial effects of this utility model are: by using a pleated filter cartridge to filter the air, under a certain air volume requirement, the industrial dust collection equipment using a pleated filter cartridge has a smaller footprint and a larger filtration area.
[0015] By setting a differential pressure gauge, the internal and external pressure difference of the filter cartridge before and after the purging can be directly observed, and it can be determined whether the filter cartridge needs to be replaced.
[0016] The device features two one-way wheels and two omnidirectional wheels at the bottom, making it easy to move the entire device. Attached Figure Description

[0024] Please refer to Figures 1-2. A mobile intelligent industrial dust collector includes a housing 4, a vertical fan 3, a filter cartridge 7, a control box 2, and a moving assembly 11. The moving assembly is located at the bottom of the housing 4 to improve its mobility. The housing 4 is internally divided into a filtration chamber and a dust collection chamber 10. An air inlet 8 is located on one side of the housing 4 corresponding to the filtration chamber, and an air outlet 1 is located on one side of the top of the filtration chamber. The filter cartridge 7 is located inside the filtration chamber and has a pleated structure (the pleated filter cartridge 7 has a larger filtration area, higher filtration efficiency, better air permeability, lower operating resistance, and stronger durability compared to filter cartridges of the same area). The filter cartridge 7 is used to trap dust in the passing dust-laden gas. The dust collection chamber 10 is located in the housing 4 below the filter cartridge 7 and is used to collect dust from the filter cartridge. The dust trapped on the cylinder 7 is collected (mainly by gravity, the trapped dust falls automatically). The top of the box 4 is integrated with an air filtration system 13, which is used to filter and regulate the pressure of the gas transmitted to the air tank 6. A vertical fan 3 is installed inside the box 4. The air tank 6 is connected to one side of the vertical fan 3. The air tank 6 is directly connected to the air outlet 1. A control box 2 is connected to one side of the vertical fan 3. The control box 2 has a built-in PLC control module. It triggers the pulse cleaning program according to the differential pressure gauge data, that is, it works together to control the opening of the vertical fan 3 and the pulse jet cleaning of the air tank 6. The output end of the vertical fan 3 is connected to the air outlet 1, and the air inlet is placed on the upper side of the air tank 6 to discharge the gas in the air tank 6 outward along the air outlet 1.
[0025] When the start button of the vertical fan 3 is pressed on the control box 2, it starts to rotate and forms a negative pressure inside. The air enters the dust collector from the air inlet 8, is filtered by the filter cartridge 7, and the purified air is discharged outside through the air outlet 1 under the action of the vertical fan 3.
[0026] In this embodiment of the invention, sound-absorbing cotton is provided in the inner wall of the housing 4 to reduce the noise generated inside the housing 4 during operation;
[0027] The vertical fan 3 has inspection doors 5 on the left and right sides corresponding to the housing 4 for internal maintenance. The inspection doors 5 use double-layer silicone sealing rings and the door locks are quick-release latch structures.
[0028] Some of the dust collection chamber 10 is hinged with door panels 9, which facilitate the handling of dust inside the dust collection chamber 10 by opening and closing the door panels 9.
[0029] The pleated filter cartridge 7 has a pleat density of 15-20 layers / cm and is made of nano-coated polyester fiber.
[0030] A perforated plate is inserted into one side of the filter cartridge 7. The perforated plate is installed inside the housing 4 to achieve a uniform installation design for the filter cartridge 7.
[0031] The air filtration system 13 is connected to the air tank 6 via a flange, and the pressure regulation range is 0.4-0.6 MPa;
[0032] The air inlet 8 is equipped with a guide plate 12 to ensure that the airflow is evenly distributed on the surface of the filter cartridge 7.
[0033] In one embodiment of the present invention, the air filtration system 13 includes a pressure regulating valve, a compressed air filter and a differential pressure gauge. The differential pressure gauge is used to monitor the air pressure difference between the upper and lower positions inside the housing 4 in real time, and to determine whether pulse cleaning is required inside the housing based on the air pressure difference.
[0034] The pressure regulating valve is connected to the inlet of the compressed air pipeline and dynamically adjusts the output pressure (0.4-0.6MPa) through a built-in spring diaphragm mechanism to ensure stable pulse cleaning air pressure. It is connected to the PLC module via a 4-20mA analog signal to support remote pressure setting and real-time feedback.
[0035] The compressed air filter is connected in series downstream of the pressure regulating valve and adopts a three-stage filtration structure (metal mesh coarse filter + centrifugal water separation + ceramic fine filter), with a filtration accuracy of ≤5μm;
[0036] The compressed air filter is equipped with an automatic drain valve at the bottom, which is linked to the PLC module and starts the draining program every 2 hours to prevent water accumulation in the pipeline;
[0037] It should be noted that the control box 2 integrates a wireless communication module, which supports remote start / stop and status monitoring;
[0038] Meanwhile, the PLC module includes a phase sequence protector, an AC contactor, and a thermal overload relay.
[0039] Phase sequence protector: Connected to the three-phase power input terminal (L1 / L2 / L3), it detects the phase sequence and phase loss status in real time;
[0040] In case of an abnormality (such as phase sequence reversal or single-phase power failure), immediately disconnect the AC contactor coil circuit and trigger PLC alarm code E01.
[0041] AC contactor: The main contacts are connected in series with the power supply line of the fan motor, and the control coil is driven by the PLC output terminal (relay contacts);
[0042] Supports remote start / stop commands (such as control box button or wireless communication module commands).
[0043] Thermal overload relay: Installed in the fan motor circuit, it senses the heat generated by the current through a bimetallic strip;
[0044] When the current exceeds the set value (e.g., 110% of the rated current), its normally closed contact opens, cutting off the power supply to the AC contactor coil.
[0045] As a preferred embodiment of the present invention, the moving component includes two one-way wheels on one side of the bottom of the housing 4 and two sets of universal wheels with braking function on the other side, which can realize the convenient movement of the housing 4.
[0046] Specifically, the casters are equipped with a hydraulic lifting and locking mechanism, which allows them to sink and support themselves when stationary;
[0047] The hydraulic lifting and locking mechanism is a mechanical-hydraulic composite device integrated into the caster wheel. It is used to achieve height adjustment, rigid locking, and shock absorption support for the equipment in both moving and stationary states. Its core functions are:
[0048] When moving: hydraulic retraction, wheels contact the ground, supporting flexible steering;
[0049] When stationary: the hydraulic drive wheel body is raised, while the locking mechanism sinks to support it, enhancing the stability of the equipment;
[0050] For details, please refer to the organization's existing technical information; it will not be elaborated upon here.
[0051] The equipment's workflow is as follows:
[0052] (1) Start-up phase: The vertical fan 3 is started through the control box 2, and a negative pressure environment is formed inside the box 4;
[0053] (2) Filtration stage: Dust-laden gas enters from the air inlet 8 and is evenly distributed to the surface of the pleated filter cartridge 7 by the guide plate 12. The dust is trapped on the outer wall of the filter cartridge 7.
[0054] (3) Dust removal stage: When the differential pressure gauge detects an internal and external pressure difference ≥1500Pa, the PLC module triggers the pulse valve, and the compressed air is sprayed out from the air tank 6 after being regulated by the air filtration system 13, blowing off the dust on the surface of the filter cartridge 7 in the opposite direction.
[0055] (4) Dust removal stage: The dust after cleaning falls into the dust collection chamber 10, and the quick-release structure of the door panel 9 makes it easy to clean regularly;
[0056] (5) Movement adjustment: When the equipment is pushed, the casters are automatically unlocked, and when stationary, the hydraulic locking mechanism sinks to support it.
[0057] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
