Description
Technical Field
[0001] This utility model relates to the field of dust removal technology for rotary air blowers, and in particular to a dust removal and feeding device. Background Technology
[0002] In industrial material handling, rotary valves are commonly used unloading devices. When conveying materials such as dust and granules, a large amount of dust easily accumulates on the surface of the impeller and inside the machine after long-term operation. If this residual dust is not cleaned in time, long-term accumulation can lead to blockage of the rotary valve, affecting the accuracy and efficiency of subsequent material conveying, and may even damage equipment components. Traditional cleaning methods are mostly manual, which not only requires workers to disassemble the rotary valve, consuming a lot of time and energy, but also easily results in incomplete cleaning, failing to guarantee the good operating condition of the rotary valve. At the same time, during manual cleaning and normal unloading of the rotary valve, dust can easily spread into the surrounding workshop environment, causing environmental pollution, endangering the health of workers, and making it impossible to effectively recycle and reuse this dust, resulting in material waste. Therefore, we have introduced a new dust collection and unloading device. Utility Model Content
[0003] The main purpose of this utility model is to provide a dust removal and feeding device that can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dust collection and feeding device includes a base. A mounting platform is fixedly mounted on the upper left side of the base via support legs. A machine body is inserted and fixedly mounted on the upper right side of the mounting platform. A dust collection device is inserted and fixedly mounted on the upper outer surface of the machine body. The lower part of the dust collection device passes through the upper end of the mounting platform and extends to the top of the base. An L-shaped discharge pipe is provided at the lower end of the machine body. A sliding groove is provided on the upper right side of the base, and an air blowing mechanism is slidably mounted inside the sliding groove. A motor is fixedly mounted on the upper left side of the mounting platform. A protective shell is provided at the upper rear of the mounting platform. The motor output... A first pulley is fixedly installed at one end via a rotating rod. A rotating rod is movably installed at the front right side of the protective shell. A second pulley is provided at the rear of the outer surface of the rotating rod. A transmission belt is movably sleeved on the outer surfaces of the first and second pulleys. The first pulley, the second pulley, and the transmission belt are all located inside the protective shell. A speed reducer is fixedly installed at the rear of the middle of the outer surface of the rotating rod. The front part of the rotating rod passes through the rear of the machine body and extends into the interior of the machine body. A blade wheel is provided at the front of the outer surface of the rotating rod. A sealing cover is movably installed at the upper end of the machine body via a hinge.
[0005] Preferably, the air blowing mechanism includes a vertical plate, which is fixedly installed on the upper rear right side of the base. An electric push rod is inserted and fixedly installed at the rear end of the vertical plate. A U-shaped seat is fixedly installed at the output end of the electric push rod. A sliding block is provided in the middle of the lower end of the U-shaped seat. An air blowing pump is provided inside the U-shaped seat. An air outlet pipe is fixedly installed at the left end of the air blowing pump. A telescopic pipe is fixedly installed at the left end of the air outlet pipe. A connecting flange is fixedly installed at the left end of the telescopic pipe and the right end of the L-shaped discharge pipe.
[0006] Preferably, the U-shaped seat is slidably mounted inside the sliding groove via a sliding block.
[0007] By adopting the above technical solution, a slidable connection between the U-shaped seat and the sliding groove is achieved, allowing the U-shaped seat to be flexibly adjusted in position along the sliding groove.
[0008] Preferably, the left end of the telescopic tube and the L-shaped discharge tube are positioned correspondingly, and the left end of the telescopic tube and the L-shaped discharge tube are detachably connected together by a connecting flange and bolts.
[0009] By adopting the above technical solution, the precise docking of the telescopic pipe and the L-shaped discharge pipe is ensured through corresponding positioning.
[0010] Preferably, the dust collection device includes an air pump, a connecting pipe is fixedly installed at the rear end of the air pump, a dust collection box is fixedly installed at the rear end of the connecting pipe, a sealing door is movably installed at the left end of the dust collection box via a hinge, a filter screen is slidably engaged in the inner front part of the dust collection box via a slot, a handle is provided at the left front end of the sealing door, a dust conveying pipe is inserted and fixedly installed at the upper rear end of the dust collection box, a circular tube is fixedly installed at the upper end of the dust conveying pipe, and six suction heads are provided on the inner surface of the circular tube.
[0011] By adopting the above technical solution: the air pump provides negative pressure power, and the dust captured by the suction head is sucked in through the dust conveying pipe and the circular pipe. The dust collection box serves as a dust collection container, and the internal filter can filter the dust. The sealed door and handle design make it easy to open the dust collection box regularly to clean the filter and the collected dust. The slotted filter is easy to disassemble quickly. Multiple suction heads are integrated through the circular pipe, which can expand the suction range.
[0012] Preferably, the six vacuum heads are arranged in a circular array at equal intervals, and all six vacuum heads are interspersed and fixedly installed on the upper part of the outer surface of the machine body.
[0013] By adopting the above technical solution, the circular array distribution enables the vacuum head to form a 360° uniform coverage area on the upper part of the machine body.
[0014] Preferably, both the air pump and the dust collection box are fixedly installed on the upper left side of the base.
[0015] By adopting the above technical solution, the air pump, dust collection box and the main body of the equipment are integrated into a whole structure, reducing the space occupied when they are installed separately.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When cleaning is required, the electric push rod pushes the U-shaped seat to adjust the position of the air pump, so that the telescopic pipe is precisely connected to the L-shaped discharge pipe through the connecting flange. After the staff seals the connection with the connecting flange gasket and bolts, the airflow generated by the air pump enters the L-shaped discharge pipe through the air outlet pipe and telescopic pipe, and is blown in a direction toward the inner wall of the machine. This can completely blow away the dust left after the impeller conveys the material, avoiding the long-term accumulation of dust that may block the machine or affect the accuracy of subsequent material conveying. Compared with manual cleaning, this is more efficient and thorough, and does not require stopping the machine to disassemble the machine, reducing equipment maintenance time and costs. 2. The air pump creates negative pressure inside the dust collection box, which drives six circularly arranged suction heads through the dust conveying pipe and circular pipe to precisely absorb the dust blown up inside the machine. The dust enters the dust collection box with the airflow and is then filtered and collected by the filter screen. The circularly arranged suction heads can cover the upper part of the machine in all directions, ensuring that the dust is absorbed without dead corners, preventing the dust from spreading to the workshop environment and causing pollution. At the same time, the filtered and collected dust can be cleaned and recycled periodically through the sealed door, effectively preventing dust from overflowing and polluting the environment and realizing dust recycling.
