Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to a dust removal mechanism for air pollution control. Background Technology

[0002] Biomass boilers are used in pharmaceutical production workshops for processes such as boiling, drying, fermentation, capsule production, and container disinfection and sterilization. During operation, these boilers emit polluting dust particles. If these dust particles continue to be released into the pharmaceutical production workshop, they can easily harm the health of the workers. The most direct way to address air pollution is through dust removal. This effectively reduces the amount of dust particles in the air. A dust removal system is a device or system used to purify particulate matter in the atmosphere. Its main function is to remove particulate matter from the air using physical or chemical methods to improve air quality and protect the environment.

[0003] For example, a dust removal mechanism for air pollution control disclosed in Chinese patent literature (announcement number: CN220715205U) places the air cup at the outlet of the biomass boiler in the pharmaceutical factory workshop. When dust is discharged from the outlet, the air cup drives the transmission rod to rotate. The rotation of the transmission rod drives the drive gear to rotate, which in turn drives the rotating frame to rotate through the driven gear. Since a brush plate is installed on the left and right side surfaces of the rotating frame, and each brush plate has bristles on the side near the filter screen, and the bristles abut against the inner wall of the filter screen, the rotation of the rotating frame can drive the brush plate to clean the filter screen, so that the filter screen can always be kept clean without stopping the machine for cleaning or requiring manual cleaning.

[0004] However, the limitations of the air cup are that it needs to be placed in a specific position to work with the airflow. In addition, the dust emitted by biomass boilers is complex and contains harmful substances produced during boiler combustion, such as heavy metal particles and unburned organic impurities. Once this dust escapes into the workshop, it will greatly affect the workshop working environment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the current limitations of using a fan-driven system and the problem that the exhaust dust can easily pollute the workshop environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust removal mechanism for air pollution control includes a dust collection box, a conical filter screen fixedly sleeved on the inner wall of the dust collection box, a driving mechanism provided at the upper end of the dust collection box, and the driving mechanism including a driving box. A connecting pipe is fixedly connected to the outside of the driving box, one end of the connecting pipe is fixedly connected to the outside of the dust collection box, the lower end of the driving box is fixedly connected to the upper end of the dust collection box, and a driving rod is rotatably connected to the inner bottom wall of the driving box through a bearing.

[0008] The drive rod is fixedly connected to the outside of a drive blade arranged in a ring array. The lower end of the drive rod extends through and to the lower end of the conical filter screen. The drive rod is fixedly connected to the outside of a symmetrically distributed cleaning brush. The upper end of the cleaning brush contacts the outer surface of the conical filter screen. The lower end of the drive rod is fixedly connected to the outside of a symmetrically distributed pressing rod.

[0009] Preferably, the drive box is externally connected to an exhaust pipe, and the inner wall of the dust collector is fixedly fitted with an annular support block, the upper end of which is provided with symmetrically distributed guide holes.

[0010] Preferably, a guide rod is movably sleeved on the inner wall of the guide hole, and an annular lifting block is fixedly connected to the upper end of each of the two guide rods. A symmetrically distributed support spring is fixedly connected to the upper end of the annular support block.

[0011] Preferably, one end of the support spring is fixedly connected to the lower end of the annular lifting block, and the upper end of the annular lifting block is fixedly connected to a series of extrusion blocks arranged in a ring.

[0012] Preferably, a conical collecting hopper is fixedly sleeved on the inner wall of the annular lifting block, and the lower end of the conical collecting hopper is fixedly connected to an external threaded pipe.

[0013] Preferably, the external thread of the externally threaded tube is connected to a collection bottle, and the externally fixed connection of the dust collection box is an air inlet pipe.

[0014] Preferably, the inner wall of the dust collector is fixedly fitted with an annular inclined baffle, and the outside of the dust collector is provided with a sealed door.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the drive mechanism enables the filtered gas to be transported to the drive box through the connecting pipe, thereby cooperating with the drive blades to drive the drive rod to rotate, thus automatically cleaning the dust adsorbed by the conical filter screen. This not only reduces the requirements for the installation location, but also prevents the dust discharged from the boiler from spreading in the workshop, greatly improving the working environment of the workshop.

[0027] Example

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a dust removal mechanism for air pollution control, including a dust removal box 1. A conical filter 2 is installed on the inner wall of the dust removal box 1 by a secure fixed connection. Compared with ordinary flat filter, it greatly increases the contact area between the filter and the dusty air, and can intercept dust particles more efficiently.

[0029] A drive mechanism is carefully installed at the upper end of the dust collector 1. The key component of this drive mechanism is the drive box 3. There is an important connecting component, the connecting pipe 31, on the outside of the drive box 3. One end of the connecting pipe 31 is tightly and fixedly connected to the outside of the dust collector 1. Its function is to introduce the relatively clean gas after it has been filtered by the conical filter screen 2 in the dust collector 1 into the drive box 3. The lower end of the drive box 3 is firmly connected to the upper end of the dust collector 1 to ensure the stability of the entire structure.

[0030] The inner bottom wall of the drive box 3 is rotatably connected to the drive rod 32 through a high-precision bearing. This connection method can ensure that the drive rod 32 can rotate flexibly and reduce friction loss during rotation. Multiple drive blades 33 are uniformly fixedly connected to the outside of the drive rod 32 in a ring array. This layout can provide stable and efficient rotational force to the drive rod 32 when the filtered gas enters the drive box 3 and impacts the drive blades 33.

[0031] The lower end of the drive rod 32 extends downward, penetrating and precisely reaching the lower end of the conical filter screen 2. Cleaning brushes 34 are symmetrically distributed and firmly fixed to the outside of the drive rod 32. The upper end of the cleaning brushes 34 maintains close contact with the outer surface of the conical filter screen 2. When the drive rod 32 rotates, the cleaning brushes 34 rotate synchronously, continuously brushing off the dust adsorbed on the outer wall of the conical filter screen 2, effectively preventing dust accumulation from adversely affecting the filter's filtration effect. Simultaneously, a squeezing rod 35 is symmetrically fixed to the lower end of the drive rod 32. The squeezing rod 35 will play an important role in the subsequent dust collection process.

[0032] In addition to the connecting pipe 31, the drive box 3 is also fixedly connected to the exhaust pipe 36. The function of the exhaust pipe 36 is to discharge the gas that has entered the drive box 3 and completed the task of driving the drive rod 32 to the external environment, so as to ensure that the gas in the drive box 3 can circulate normally and maintain the stable operation of the entire drive mechanism.

[0033] An annular support block 37 is fixedly fitted onto the inner wall of the dust collection box 1. The annular support block 37 acts as a solid base, providing stable support for the subsequent dust collection components. At the upper end of the annular support block 37, symmetrically distributed guide holes 38 are evenly opened. A guide rod 39 is movably fitted onto the inner wall of the guide hole 38. The fit between the guide rod 39 and the guide hole 38 is extremely precise, ensuring that the guide rod 39 can move smoothly up and down within the guide hole 38 while preventing wobbling or deviation. The upper ends of both guide rods 39 are firmly fixedly connected to the annular lifting block 310, which allows the annular lifting block 310 to move up and down synchronously with the movement of the guide rods 39.

[0034] At the upper end of the annular support block 37, symmetrically distributed support springs 311 are fixedly connected. The support springs 311 have a suitable elastic coefficient, and one end of them is fixedly connected to the lower end of the annular lifting block 310. The support springs 311 play an important role in buffering and resetting in the whole system. When the annular lifting block 310 is subjected to external force and moves downward, the support springs 311 are compressed and store elastic potential energy. When the external force disappears, the support springs 311 release elastic potential energy and drive the annular lifting block 310 to rise and reset.

[0035] The upper end of the annular lifting block 310 is uniformly and fixedly connected with multiple extrusion inclined blocks 312 in a circular array. The shape and angle of the extrusion inclined blocks 312 are precisely designed. When the extrusion rod 35 at the lower end of the drive rod 32 rotates with the drive rod 32 to contact the extrusion inclined block 312, the extrusion rod 35 will generate an oblique pressure on the extrusion inclined block 312. Since the extrusion inclined block 312 is fixedly connected to the annular lifting block 310, this oblique pressure will be decomposed into a downward force, so that the annular lifting block 310 overcomes the elastic force of the support spring 311 and moves downward along the guide rod 39 in the guide hole 38. When the extrusion rod 35 continues to rotate and disengages from the extrusion inclined block 312, the elastic force of the support spring 311 will drive the annular lifting block 310 to rise and reset.

[0036] On the inner wall of the annular lifting block 310, a conical collection hopper 313 is installed by a tight fixed connection. The conical collection hopper 313 has a cleverly designed shape, with its large opening facing upwards and its small opening facing downwards, which can effectively collect the dust brushed off the conical filter screen 2 by the cleaning brush 34. When the annular lifting block 310 moves up and down under the action of the squeezing rod 35 and the squeezing inclined block 312, the conical collection hopper 313 will also move synchronously.

[0037] The lower end of the conical collecting hopper 313 is fixedly connected to the external threaded pipe 314. The external thread size and precision of the external threaded pipe 314 meet the standard requirements, which will facilitate the connection of the subsequent collecting bottle 315. Through the external threaded pipe 314, dust can flow smoothly from the conical collecting hopper 313 into the collecting bottle 315.

[0038] The external threaded tube 314 is connected to the collection bottle 315 through a precise threaded connection. This threaded connection method is not only easy to install, but also ensures the sealing of the connection and prevents dust leakage. The collection bottle 315 is used to collect the dust that slides down from the conical collection hopper 313 through the external threaded tube 314, so as to realize the centralized collection and temporary storage of dust.

[0039] Outside the dust collector 1, an air inlet pipe 4 is fixedly connected. The air inlet pipe 4 is the air intake channel of the entire dust collection mechanism. Polluted air containing dust particles is introduced into the dust collector 1 through the air inlet pipe 4 to provide air to be treated for the subsequent dust collection process.

[0040] The inner wall of the dust collector 1 is fixedly fitted with an annular inclined baffle 5. The annular inclined baffle 5 can prevent dust from accumulating excessively above the annular lifting block 310 inside the dust collector 1, ensuring the smooth progress of the entire dust removal process.

[0041] A sealing door 6 is provided on the outside of the dust collection box 1. The sealing door 6 has good sealing performance and can ensure the sealing of the dust collection box 1 under normal working conditions, preventing dust from leaking into the external environment.

[0042] The working process of this utility model:

[0043] Step one: First, polluted air containing dust particles enters the dust collector 1 through the air inlet pipe 4 outside the dust collector 1. After entering the dust collector 1, due to the conical filter 2, dust particles are intercepted and adsorbed on the surface and inside of the conical filter 2, initially achieving separation of air and dust. The relatively clean air after filtration continues to flow in the dust collector 1, and the filtered gas is transported to the drive box 3 through the connecting pipe 31. The airflow entering the drive box 3 impacts the drive blades 33, which are fixed on the drive rod 32 and arranged in a ring array. The drive blades 33 are forced to drive the drive rod 32 to rotate. Since the lower end of the drive rod 32 passes through and extends to the lower end of the conical filter 2, and a symmetrically distributed cleaning brush 34 is fixedly connected to its exterior, the cleaning brush 34 rotates synchronously with the drive rod 32. Its upper end is in close contact with the exterior of the conical filter 2, brushing off the dust adsorbed on the outer wall of the conical filter 2, realizing automated cleaning of the conical filter 2, and avoiding dust accumulation that affects the filter effect.

[0044] Step two: The symmetrically distributed extrusion rods 35, fixedly connected to the lower end of the drive rod 32, also rotate with the drive rod 32. The rotation of the extrusion rods 35 acts on the extrusion inclined blocks 312, which are fixedly connected to the upper end of the annular lifting block 310 and are arranged in a circular array. When the extrusion rods 35 contact the extrusion inclined blocks 312, they exert a downward pressure on the annular lifting block 310, causing it to overcome the elastic force of the support spring 311 and move downward along the guide rod 39 within the guide hole 38. A conical collecting hopper 313 is fixedly sleeved on the inner wall of the annular lifting block 310. When the annular lifting block 310 moves downward... The conical collecting hopper 313 also moves down synchronously. When the squeezing rod 35 disengages from the squeezing inclined block 312, the elastic force of the supporting spring 311 drives the conical collecting hopper 313 to rise and reset. Through vibration, the dust that was previously brushed off the conical filter screen 2 by the cleaning brush 34 slides down the external threaded tube 314 at the lower end of the conical collecting hopper 313 into the collecting bottle 315, realizing the collection and temporary storage of dust. When the collecting bottle 315 is full of dust, the collecting bottle 315 can be easily replaced by opening the sealing door 6 set on the outside of the dust removal box 1, so as to continuously maintain the efficient operation of the dust removal mechanism.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
