Description

Technical Field

[0001] The invention belongs to the technical field of dust removal equipment, and in particular relates to a fully enclosed negative pressure shutter wheel dust removal device and a use method thereof. Background Art

[0002] In the field of modern industrial manufacturing, especially in metal processing, wood processing, stone processing and other industries, grinding process is a common and crucial processing procedure. As a high-efficiency grinding equipment, the flap wheel grinder is widely used for grinding and polishing the surface of various materials to improve the quality and appearance of the product. During the working process of the flap wheel grinder, due to the violent friction between the high-speed rotating flap wheel and the processed material, a large amount of dust will be generated. This dust will not only permeate the working environment, but also seriously affect the operator's vision and work comfort.

[0003] The current flap wheel grinder is equipped with a simple dust collection hood. The main principle is to set a hood above the grinding area, use the negative pressure generated by the fan to suck away the generated dust, and filter the dust through the filter. However, the dust will accumulate on the surface of the filter, and the air permeability of the filter will gradually decrease, resulting in an increase in the pressure loss of the fan. In order to overcome the pressure loss, more energy is needed to maintain the operation of the fan, which increases production costs.

[0004] To this end, we provide a fully enclosed negative pressure shutter wheel dust removal device and a method of use to solve the above-mentioned problems. Summary of the invention

[0006] To solve the above technical problems, the present invention is implemented through the following technical solutions.

[0007] The present invention discloses a fully enclosed negative pressure louver wheel dust removal device and a use method thereof, comprising a support cover, a rotating motor is installed on one side of the support cover, an output end of the rotating motor passes through the interior of the support cover and is installed with a louver grinding wheel, and a ventilation pipe is connected to one side of the support cover; a ventilation assembly is arranged on one side of the support cover, the ventilation assembly comprises a support pipe sleeved on the surface of the ventilation pipe, a three-way pipe connected to one side of the support pipe, an exhaust pipe connected to one side of the three-way pipe, a driving motor installed on one side of the support cover, a driving shaft installed on the output end of the driving motor, and exhaust fan blades arranged inside the three-way pipe, and dust inside the support cover is discharged through the ventilation assembly; a cleaning assembly is arranged on one side of the support cover, the cleaning assembly comprises a metal filter installed inside the support pipe, a cleaning brush plate installed inside the ventilation pipe, and the accumulated dust is cleaned by the cleaning assembly; a transmission assembly is arranged on one side of the support cover, the transmission assembly comprises a gear installed on the surface of the driving shaft, and a gear ring installed on the surface of the support pipe, and the cleaning range of the cleaning brush plate is increased by the transmission assembly.

[0008] The present invention is further configured such that two sides of the gear are respectively meshed with two sets of gear rings, and the other end of the drive shaft passes through the interior of the three-way pipe and is fixedly connected to the exhaust fan blades.

[0009] The present invention is further configured such that one side of the cleaning brush plate contacts the metal filter screen, and the surface of the three-way pipe is movably connected to the inner wall of the support tube through a first bearing.

[0010] The present invention is further configured such that a filter cartridge is movably connected inside the exhaust pipe, a dust screen is installed inside the filter cartridge, and air adsorbent particles are arranged on the top and bottom of the dust screen.

[0011] The present invention is further configured such that a rotating shaft is installed on one side of the filter cartridge, a first belt pulley is fixedly connected to the surface of the rotating shaft, and a second belt pulley is fixedly connected to the surface of the drive shaft.

[0012] The present invention is further configured such that a conveying belt is sleeved between the first belt pulley and the second belt pulley, and the other end of the rotating shaft is movably connected to the support cover via a second bearing.

[0013] The present invention is further configured such that the bottom of the ventilation pipe is connected to a collecting cover, and a collecting shell is provided through one side of the collecting cover.

[0014] The present invention is further configured such that one side of the support cover is connected to an air intake pipe, a dust filter is installed inside the air intake pipe, a sealing door is movably connected to the front side of the support cover, and a base is fixedly connected to the bottom of the support cover.

[0015] The present invention is further configured such that a processing table is installed inside the support cover, a moving seat is slidably connected to the top of the processing table, and a hydraulic rod is installed at the rear side of the moving seat.

[0016] A method for using a fully enclosed negative pressure shutter wheel dust removal device comprises the following steps: S1: When the worker starts the rotating motor to drive the louver grinding wheel to grind the workpiece, a large amount of dust will be generated. At this time, the driving motor is started, and the driving motor cooperates with the driving shaft to drive the exhaust fan blades to rotate. The exhaust fan blades can drive the air flow, and use the negative pressure effect to introduce the dust and gas inside the support cover into the ventilation pipe. After the dust enters the ventilation pipe, it is filtered by the metal filter. The filtered gas enters the exhaust pipe through the three-way pipe, and the exhaust gas is adsorbed and filtered by the air adsorbent particles inside the filter cartridge; S2: The driving shaft rotates while driving the gear to rotate. The gear cooperates with the gear ring to drive the support tube to rotate. The support tube drives the metal filter to rotate. At this time, the position of the cleaning brush plate remains unchanged. Since the metal filter is circular in design, the dust agglomerated on the surface of the metal filter can be cleaned by the cleaning brush plate during rotation. After the agglomerated dust is cleaned, it will fall into the collection shell for collection, which is convenient for the staff to clean in a centralized manner, so that the metal filter can always maintain a good filtering effect and improve the dust removal effect; S3: When the driving shaft rotates, it drives the first belt pulley to rotate. The first belt pulley cooperates with the conveying belt to drive the second belt pulley to rotate. The second belt pulley cooperates with the rotating shaft to drive the filter cartridge to rotate. When the rotating shaft drives the filter cartridge to rotate, the air adsorbent particles inside can be turned over to increase the contact range with the air and improve the adsorption and filtration effect.

[0017] The present invention has the following beneficial effects.

[0018] 1. The present invention significantly improves the dust collection and filtration efficiency through the design of the ventilation component and the cleaning component. The metal filter is used to initially filter the dust, and then the exhaust gas is deeply adsorbed by the air adsorbent particles, which effectively reduces the dust pollution to the environment. In addition, the design of the cleaning component enables the metal filter to be automatically cleaned, avoiding the reduction of the filtration effect due to dust accumulation, and ensuring the continuity and stability of the dust removal effect.

[0019] 2. The present invention further enhances the degree of automation of the device through the ingenious design of the transmission component. The drive shaft not only drives the exhaust fan blades to rotate, but also realizes the automatic cleaning of the metal filter through the cooperation of the gears and the gear rings. At the same time, through the transmission of the belt pulley, the air adsorbent particles in the filter cartridge can be evenly turned over, increasing the contact area with the air, thereby improving the adsorption efficiency. This design not only simplifies the operation process, but also reduces the maintenance cost and improves the overall performance of the device.

[0020] 3. The support cover of the present invention adopts a fully enclosed design to reduce the spillage of dust, improve the working environment, and protect the health of operators. The exhaust fan blades and air adsorbent particles work together to make the air flow path reasonable, reduce air flow resistance, and reduce the energy consumption of the fan. At the same time, the automatic cleaning component reduces the additional energy consumption caused by dust blockage, which greatly reduces the production cost as a whole and improves the economic benefits.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
