The airflow is discharged from the air outlet mechanism, and the filtered airflow is discharged to maintain the internal and external pressure of the equipment. A connecting frame is fixedly connected to the upper side of the inner wall of the box shell, and a connecting rod is slidably connected to the outer side of the connecting frame. A clamping block is fixedly connected to one side of the outer side of the connecting rod. The door panel of the box shell is opened, and the cylindrical filter is placed on the upper side of the pushing mechanism. The cylindrical filter is pushed to move toward the clamping block by the pushing mechanism. The cylindrical filter squeezes the clamping block, so that the clamping block drives the connecting rod to move toward the connecting frames on both sides, squeezing and contracting the first spring. The clamping block clamps the cylindrical filter through the reaction of the spring structure, so as to achieve the function of the fixing component. The outer side of the connecting rod is sleeved with a first spring.

A connecting plate is fixedly connected to one side of the outer side of the sliding rod, and the rotation of the central shaft is controlled by a motor. The central shaft drives the impact shell to rotate. During the rotation of the impact shell, the sliding rod is caused to slide on the inner side of the barrel-shaped outer shell by centrifugal force, so that the connecting plate impacts the inner wall of the cylindrical filter, thereby shaking off the dust on the surface of the component and peeling off the powder adsorbed on the surface of the component, so as to facilitate the subsequent continuous operation of the component and the processing of the powder, and prevent excessive dust adsorption on the surface of the cylindrical filter, affecting the subsequent filtering effect.

[0007] Preferably, a silicone block is fixedly connected to the side of the connecting plate away from the second spring. The silicone block is made of silicone material, which has good wear resistance and buffering effect, thereby providing a certain protection for the components, reducing wear between components, thereby extending the service life of the components, and secondly reducing a certain collision effect to avoid damage to components due to excessive impact pressure. A block surface groove is provided on the outer side of the silicone block. By providing the block surface groove, the deformation performance of the component is increased, thereby further improving the buffering effect. Secondly, when the motor stops.

When the top of the cylindrical filter is clamped, the receiving plate is subjected to the reaction of the component, causing the receiving rod to squeeze the third spring, thereby achieving the effect of shock absorption and buffering, reducing the squeezing force, avoiding damage to the component, and increasing the fault tolerance space for the component. The receiving rod is fixedly connected to one side of the outside of the receiving rod with the receiving plate, and the outside of the receiving plate is fixedly connected to one side away from the receiving rod with a rubber plate. The rubber plate is made of rubber material, and the rubber material increases the anti-slip effect of the component, improves the stability of the fixed component, and prevents shaking during the movement of the component.

[0010] Preferably, the air outlet mechanism includes an air outlet pipe, and a funnel plate is fixedly connected to the inner wall of the air outlet pipe on one side close to the box shell. After the airflow passes through the cylindrical filter, it flows to one side of the air outlet pipe, and is guided by the funnel plate to move to the grille plate, thereby achieving the effect of filtering powder, thereby reducing powder overflow, protecting the external environment, and reducing safety hazards to the human body. The inner side of the funnel plate is fixedly connected to the grille plate. When moving toward the grille plate, the airflow first impacts the barrier plate, thereby reducing the filtering pressure of the grille plate, and having a certain barrier effect on the dust flow. The effect is achieved by attenuating the powder in the airflow. A telescopic rod is fixedly connected to the outer side of the funnel plate. A fourth spring is sleeved on the outer side of the telescopic rod. After the airflow impacts the baffle plate, the telescopic rod drives the fourth spring to squeeze, thereby reducing the impact pressure of the airflow. The funnel plate and the baffle plate are adapted to promote the blocked airflow to move along the funnel plate. Secondly, the funnel plate adopts a structure with one end wide and the other end narrow.

On the one hand, it reduces powder adsorption and avoids excessive accumulation of powder that affects the airflow effect. On the other hand, it promotes powder flow through friction, so that the residual powder enters the interior of the equipment and reduces resource waste.

[0013] Preferably, the output mechanism includes a second fan. After the powder is adsorbed by the cylindrical filter, the powder on the surface of the cylindrical filter is impacted and shaken to drop by the impact mechanism, so as to maintain the filtering effect of the equipment.

[0015] The present invention provides a powder recovery and filtering device that is convenient for replacing a filter element. It has the following beneficial effects:

[0016] 1. The powder recovery and filtering equipment which is convenient for replacing the filter element has a box mechanism design. The box shell door panel is opened, and the cartridge filter is placed on the upper side of the push-up mechanism. The cartridge filter is pushed to move toward the clamping block by the push-up mechanism. The cartridge filter squeezes the clamping block so that the clamping block drives the connecting rod to move toward the connecting frames on both sides, squeezes and contracts the first spring, and the clamping block clamps the cartridge filter through the reaction of the spring structure, so as to achieve the function of fixing the component. The cartridge filter is supported by the push-up mechanism to provide supporting force for the component to maintain the stability of the object being fixed. When the push-up mechanism is lowered, the cartridge filter has no bottom supporting force, so as to facilitate disassembly and replacement, so as to meet different operation requirements. After the cartridge filter is fixed, the dust enters the box shell from the input mechanism and contacts the cartridge filter, so as to filter and adsorb the dust in the airflow, so as to facilitate the collection of dust, reduce resource waste, and facilitate subsequent recycling. The airflow is discharged from the air outlet mechanism, and the filtered airflow is discharged to maintain the internal and external pressure of the equipment.

[0017] 2. The powder recovery and filtering equipment which is easy to replace the filter element is designed with an impact mechanism. The central shaft is controlled to rotate by a motor, and the central shaft drives the impact shell to rotate. During the rotation of the impact shell, the sliding rod slides on the inner side of the barrel-shaped shell through centrifugal force, so that the connecting plate impacts the inner wall of the cylindrical filter, thereby shaking the dust on the surface of the component and peeling off the powder adsorbed on the surface of the component, so as to facilitate the subsequent continuous operation of the component and the processing of the powder, and prevent the excessive adsorption of dust on the surface of the cylindrical filter, thereby affecting the subsequent filtering effect. The silicone block is made of silicone material, which has good wear resistance and buffering effect, so as to have a certain protective effect on the component, reduce the wear between the components, and thus extend the service life of the components. Secondly, it reduces a certain collision effect and avoids damage to the components due to excessive impact pressure. By opening a block surface groove, the deformation performance of the component is increased, and the buffering effect is further improved. Secondly, when the motor stops, the rebound effect of the second spring is used to shrink the equipment, avoid long-term contact with the inner wall of the component, and reduce excessive friction between the components.

[0018] 3. The powder recovery and filtration equipment, which is convenient for replacing the filter element, is designed with a push-up mechanism. The electric push rod controls the lifting of the receiving frame to achieve the function of pushing the components to be lifted. The cylindrical filter is moved to the top of the box shell by lifting, so as to facilitate the fixing of the components and support the components at the same time. The auxiliary rod assists the electric push rod in lifting and lowering, so as to keep the components lifted evenly and avoid displacement during the lifting process. Secondly, when the cylindrical filter is pushed up and squeezed, the buffer mechanism plays a role of shock absorption and buffering to avoid damage to the components due to excessive squeezing force, thereby extending the service life of the equipment.

[0019] Fourth, the powder recovery and filtration equipment which is easy to replace the filter element has an air outlet mechanism design. After the airflow is filtered by the cylindrical filter, it flows to one side of the air outlet pipe, and is guided to move to the grille plate by the funnel plate, so as to filter the powder, thereby reducing powder overflow, protecting the external environment, and reducing safety hazards to the human body. When moving to the grille plate, the airflow first impacts the baffle plate, thereby reducing the filtering pressure of the grille plate, and has a certain blocking effect on the dust flow, thereby attenuating the powder in the airflow. After the airflow impacts the baffle plate, the telescopic rod drives the fourth spring to squeeze, thereby reducing the impact pressure of the airflow, and the funnel plate is adapted to the baffle plate to promote the blocked airflow to move along the funnel plate. Secondly, the funnel plate adopts a structure with one end wide and the other end narrow. According to the Bernoulli principle, by reducing the diameter of the pipeline, the flow speed of the gas is increased and the discharge effect is accelerated.

[0020] 5. The powder recovery and filtration equipment, which is easy to replace the filter element, is designed with an output mechanism. After the powder is adsorbed by the cylindrical filter, the powder on the surface of the cylindrical filter is impacted and shaken off by the impact mechanism to maintain the filtering effect of the equipment. The powder falls to the bottom of the inner wall of the box shell, and the second fan generates wind force to absorb the powder on the inner wall of the equipment, so as to achieve the effect of discharging the powder and avoid the excessive internal powder affecting the operation of the equipment. The discharged powder is stored to facilitate subsequent processing, and the grille cover is used to block impurities to avoid external impurities from entering the equipment and prevent pollution to the equipment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: a powder recovery and filtering device that is easy to replace a filter element, comprising a box mechanism 1, a motor 4 is fixedly connected to the top of the box mechanism 1, an output mechanism 3 is fixedly connected to the bottom of one side outside the box mechanism 1, an input mechanism 2 is fixedly connected to the side of the box mechanism 1 away from the output mechanism 3, and a cylindrical filter 5 is arranged inside the box mechanism 1;

Open the door panel of the box shell 11, place the cylindrical filter 5 on the upper side of the pushing mechanism 14, and push the cylindrical filter 5 to move toward the clamping block 19 through the pushing mechanism 14. The cylindrical filter 5 squeezes the clamping block 19, so that the clamping block 19 drives the connecting rod 17 to move toward the connecting frame 16 on both sides, squeezes and contracts the first spring 18, and the clamping block 19 clamps the cylindrical filter 5 through the reaction of the spring structure, so as to achieve the function of fixing the component, and the cylindrical filter 5 is supported by the pushing mechanism 14 to provide supporting force for the component to maintain the stability of the object. When the pushing mechanism 14 is lowered, the cylindrical filter 5 has no bottom supporting force, so it is easy to disassemble and replace, so as to meet different operation requirements. After the cylindrical filter 5 is fixed, the dust enters the inside of the box shell 11 from the input mechanism 2 and contacts the cylindrical filter 5, so as to filter and adsorb the dust in the airflow, so as to facilitate the collection of dust, reduce resource waste, and facilitate subsequent recycling. The airflow is discharged from the air outlet mechanism 15, and the filtered airflow is discharged to maintain the internal and external pressure of the equipment.

[0035] The impact mechanism 13 includes an impact shell 131, a barrel-shaped shell 132 is fixedly connected to the inner side of the impact shell 131, a sliding rod 133 is slidably connected to the inner side of the barrel-shaped shell 132, a second spring 134 is sleeved on the outer side of the sliding rod 133, and a connecting plate 135 is fixedly connected to one side of the outer side of the sliding rod 133. The central shaft 12 is controlled to rotate by the motor 4, and the central shaft 12 drives the impact shell 131 to rotate. During the rotation of the impact shell 131, the sliding rod 133 slides inside the barrel-shaped shell 132 by centrifugal force, so that the connecting plate 135 impacts the inner wall of the cylindrical filter 5, thereby shaking the dust on the surface of the component and peeling off the powder adsorbed on the surface of the component, so as to facilitate the subsequent continuous operation of the component and the processing of the powder, and prevent the surface of the cylindrical filter 5 from being adsorbed too much dust, which affects the subsequent filtering effect.

[0036] A silicone block 136 is fixedly connected to the side of the connecting plate 135 away from the second spring 134, and a block surface groove 137 is provided on the outer side of the silicone block 136.

[0037] The lifting mechanism 14 includes a lifting base 141, an electric push rod 142 is fixedly connected to the middle of the top of the lifting base 141, a receiving frame 143 is fixedly connected to one side of the outside of the electric push rod 142, and auxiliary rods 144 are fixedly connected to the four sides of the bottom of the receiving frame 143. The bottom of the auxiliary rod 144 is fixedly connected to the top of the lifting base 141, and a buffer mechanism 145 is slidably connected to the outside of the receiving frame 143. The receiving frame 143 is controlled to be lifted and lowered by the electric push rod 142, so as to achieve the effect of pushing the lifting of the components. The cylindrical filter 5 is moved to the top of the box shell 11 by lifting and lowering, so as to facilitate the fixing of the components and support the components at the same time. The auxiliary rod 144 plays a role in assisting the electric push rod 142 to lift and lower, so as to keep the components lifted and lowered evenly and avoid deviation during the lifting process. Secondly, when the cylindrical filter 5 is pushed and squeezed, the buffer mechanism 145 plays a role of shock absorption and buffering, so as to avoid damage to the components due to excessive squeezing force, thereby extending the service life of the equipment.

[0038] The buffer mechanism 145 includes a receiving rod 1451, a third spring 1452 is sleeved on the outer side of the receiving rod 1451, a receiving plate 1453 is fixedly connected to one side of the receiving rod 1451, and a rubber plate 1454 is fixedly connected to one side of the receiving plate 1453 away from the receiving rod 1451.

When moving to the grid plate 153, the airflow first impacts the baffle plate 156, so as to reduce the filtering pressure of the grid plate 153, and has a certain blocking effect on the dust flow, thereby attenuating the powder in the airflow. After the airflow impacts the baffle plate 156, the telescopic rod 154 drives the fourth spring 155 to squeeze, so as to reduce the impact pressure of the airflow, and the funnel plate 152 is adapted to the baffle plate 156, so as to promote the blocked airflow to move along the funnel plate 152. Secondly, the funnel plate 152 adopts a structure with one end wide and the other end narrow. According to the Bernoulli principle, by reducing the diameter of the pipeline, the flow speed of the gas is increased and the discharge effect is accelerated.

Figures 7 and 8 As shown, the input mechanism 2 includes a first fan 21, an input pipe 22 is fixedly connected to the outside of the first fan 21, a fixing frame 24 is fixedly connected to the side of the inner wall of the input pipe 22 close to the first fan 21, a connecting shaft 25 is fixedly connected to the outside of the fixing frame 24, a wall scraping mechanism 26 is rotatably connected to the outside of the connecting shaft 25, and a perforated plate 23 is fixedly connected to the side of the inner wall of the input pipe 22 away from the first fan 21. A hose can be sleeved on the groove on the outside of the input pipe 22, and the hose is in contact with the powder. The wind force is generated by the first fan 21, so that the wind force drives the powder to be absorbed, thereby achieving the effect of collecting dust. Secondly, the wind force drives the wall scraping mechanism 26 to rotate, and the wall scraping mechanism 26 rubs the inner wall of the pipe, thereby reducing the powder on the inner wall of the pipe, prompting the powder to enter the inside of the box shell 11, and reducing the powder residue.

[0041] The wall scraping mechanism 26 includes a connecting column 261, a wall scraping bracket 262 is fixedly connected to the outer side of the connecting column 261, a scraper 264 is fixedly connected to the outer side of the scraper bracket 262 away from the connecting column 261, and a first blade 263 is fixedly connected to the outer side of the scraper bracket 262. The first blade 263 contacts the wind force, thereby driving the connecting column 261 to rotate, so that the scraper bracket 262 drives the scraper 264 to rotate and scrape the inner wall of the pipeline, thereby cleaning the inner wall of the pipeline, thereby reducing powder adsorption. On the one hand, it reduces powder adsorption and avoids excessive accumulation of powder to affect the airflow effect. On the other hand, it promotes powder flow through friction, so that the residual powder enters the interior of the equipment and reduces resource waste.

[0042] The third embodiment is based on the first and second embodiments. Figures 9 and 10 As shown, the output mechanism 3 includes a second fan 31, a grille cover 32 is fixedly connected to one side of the outside of the second fan 31, a connection end 33 is fixedly connected to the inner wall of the grille cover 32 away from the second fan 31, a support shaft 34 is fixedly connected to the inner side of the connection end 33, and a cleaning mechanism 35 is rotatably connected to the outer side of the support shaft 34. After the powder is adsorbed by the cylindrical filter 5, the powder on the surface of the cylindrical filter 5 is impacted and shaken to fall by the impact mechanism 13, so as to maintain the filtering effect of the equipment, and the powder falls to the bottom of the inner wall of the box shell 11, and the wind is generated by the second fan 31 to absorb the powder on the inner wall of the equipment, so as to achieve the effect of discharging the powder, avoid the excessive internal powder from affecting the operation of the equipment, and store the discharged powder for subsequent processing. The grille cover 32 is used to block impurities to prevent external impurities from entering the interior of the equipment and prevent pollution to the equipment.

[0043] The cleaning mechanism 35 includes a cylindrical block 351, the outer side of the cylindrical block 351 is fixedly connected to a square shell 352, the inner side of the square shell 352 is slidably connected to a connecting rod 353, the outer side of the connecting rod 353 is sleeved with a fifth spring 354, a second blade 358 is fixedly connected to the middle of the outer side of the cylindrical block 351, a cleaning frame 355 is fixedly connected to the side of the outer side of the connecting rod 353 away from the square shell 352, the inner side of the cleaning frame 355 is rotatably connected to a friction column 356, and the outer side of the friction column 356 is fixedly connected to a rubber block 357. Wind is generated by the second fan 31, and the wind drives the components to rotate through the second blades 358. Through the centrifugal force generated by the rotation, the connecting rod 353 slides on the inside of the square shell 352, so that the friction column 356 rotates and rubs the inside of the grille cover 32, so as to achieve the effect of cleaning powder and avoid clogging the holes of the components by powder, thereby preventing the effect of affecting the entry of powder. A rubber block 357 is arranged on the outside of the friction column 356. During the rotation, the rubber block 357 cleans the holes of the grille cover 32, thereby further improving the cleaning effect. When the equipment stops operating, it is reacted by the fifth spring 354, causing the connecting rod 353 to shrink, so as to avoid long-term friction of the components, which causes serious wear of the components, thereby extending the service life of the components.

[0044] When in use, the door panel of the box mechanism 1 is opened, and the staff holds the cylindrical filter 5 and places it on the pushing mechanism 14. The cylindrical filter 5 is pushed to the top of the box shell 11 by the pushing mechanism 14, and the cylindrical filter 5 is clamped by the box mechanism 1 to achieve the effect of fixing and clamping the components, thereby maintaining the stability of the equipment and avoiding shaking during operation. At the same time, the cylindrical filter 5 is supported by the pushing mechanism 14 to avoid shaking during operation and causing the components to slide down, thereby further improving the support for the cylindrical filter 5. After the cylindrical filter 5 is fixed, the powder enters the box shell 11 from the input mechanism 2, and the powder in the airflow is filtered and adsorbed by the cylindrical filter 5. The filtered airflow is discharged outward from the air outlet mechanism 15 to balance the internal and external pressures of the equipment. During the operation of the equipment, the internal pressure of the equipment will change with the continuous entry of gas and the filtering of dust. The existence of the air outlet can keep the internal pressure of the equipment balanced with the external environmental pressure, prevent the equipment from being damaged due to excessive pressure, or prevent the external air from flowing back due to low pressure, affecting the dust recovery effect. After a long period of operation, too much powder is adsorbed on the surface of the cylindrical filter 5 to avoid affecting the subsequent adsorption effect. The central shaft 12 is controlled to rotate by the motor 4. The rotation of the central shaft 12 drives the impact mechanism 13 to impact the inside of the cylindrical filter 5, so that the cylindrical filter 5 is shaken, and the powder on the surface of the component is cleaned by the amplitude of the component shaking, and the powder on the surface of the cylindrical filter 5 is peeled off, thereby extending the filtering effect of the component. After the powder is peeled off, it falls to the bottom of the inner wall of the box shell 11, and wind force is generated by the output mechanism 3. The powder inside the equipment is absorbed by the wind force, so as to achieve the discharge effect of the internal powder, avoid excessive powder inside the equipment after a long period of operation, thereby affecting the subsequent filtering effect of the equipment. When the cylindrical filter 5 needs to be replaced, it is contracted by the lifting mechanism 14, so as to facilitate the disassembly of the cylindrical filter 5, so as to facilitate replacement.
