Description

Technical Field

[0001] The invention belongs to the technical field of vacuum pump air intake filtration, and in particular relates to a vacuum pump air intake filtration mechanism capable of effectively filtering impurities. Background Art

[0002] The vacuum pump air intake filter mechanism is an important component installed at the air inlet of the vacuum pump. Its main function is to filter various impurities in the pumped gas, such as garbage fragments, dust and particles, to protect the vacuum pump from these impurities.

[0003] At present, there is a Chinese invention with the publication number of CN118267809A. This invention relates to the technical field of filters, and specifically to a vacuum pump air intake filter with a self-cleaning function, comprising a filter cartridge and a filter screen, a driving shaft is arranged on the top of the filter cartridge, and a first shell and a second shell are arranged inside and outside the filter screen respectively; a transmission assembly is arranged between the first shell and the second shell, and the present invention drives the filter screen to rotate intermittently through the driving shaft, so that the filter screen can filter the gas evenly, and at the same time, the driving shaft also drives the movement of the transmission assembly, and the first shell and the second shell are driven by the transmission assembly to move relative to each other, so that a working area that can partially cover the filter screen wall is formed on the filter screen, and the dust is washed out by the reverse airflow, and then the dust is collected by the second shell, so that the filter can clean the local part of the filter screen without stopping the machine, restore the performance of the filter screen, and extend the service life of the filter screen. At the same time, the dust generated during cleaning can be collected, reducing the number of maintenance times for the filter screen.

[0004] The existing vacuum pump air intake filter mechanism that can effectively filter impurities has the following disadvantages when used:

[0005] 1. When filtering the air intake of the vacuum pump, only a single and simple filter is used for unified filtering. This will not only accelerate the blockage, but also fail to more effectively remove the small garbage fragments, dust and tiny particles carried in the air. At the same time, the simple filter is unable to remove moisture, causing high humidity air to make impurities more easily adhere to the filter, ultimately reducing the filtration efficiency;

[0006] 2. While filtering the air intake of the vacuum pump, it is impossible to effectively clean the filter mechanism without opening it, which not only affects the service life of the filter, but also indirectly affects its operating efficiency due to frequent opening and cleaning. Summary of the invention

[0007] The purpose of the present invention is to provide an existing vacuum pump air intake filter mechanism that can effectively filter impurities, and the advantages are:

[0008] 1. When filtering the air intake of the vacuum pump, a combined filter is used for separate filtering, which can reduce blockage and more effectively remove small garbage fragments, dust and tiny particles carried in the air. At the same time, it can also effectively remove moisture, making it dry and making it difficult for impurities to adhere to the filter, thereby improving the filtering efficiency;

[0009] 2. While filtering the air intake of the vacuum pump, the filter mechanism can be effectively cleaned without opening it, thereby increasing the service life of the filter and improving the operating efficiency.

[0010] The above technical objectives of the present invention are achieved through the following technical solutions: a vacuum pump air intake filter mechanism capable of effectively filtering impurities, comprising a filter box, the rear side of the filter box is connected to an air intake pipe, the front side of the filter box is connected to a vacuum pump air intake pipe, a filter mechanism is arranged inside the filter box, a cleaning mechanism is arranged inside the filter box, the filter mechanism comprises a coarse filter component, a dehumidification component, a temperature control component, a fine filter component, a micro-filter component and a docking component, the coarse filter component is arranged at the rear side of the filter box, the dehumidification component is arranged at the rear side of the filter box, and the dehumidification component is located at the coarse filter component. The temperature control component is arranged on the left side of the filter box, the temperature control component is electrically connected to the dehumidification component, the fine filter component is arranged in the middle of the filter box, the micro filter component is arranged on the front side of the filter box, the docking components are respectively arranged on the inner sides of the coarse filter component, the fine filter component and the micro filter component, the cleaning mechanism includes a brushing component, a lower row component and a collecting component, the brushing group is arranged in the filter box, the brushing components are respectively located on the outer sides of the coarse filter component, the fine filter component and the micro filter component, the lower row component is connected to the bottom of the filter box, and the collecting component is arranged at the bottom of the lower row component.

[0011] By adopting the above technical scheme, by setting up a filtering mechanism and a cleaning mechanism, the gas enters the filter box from the suction pipe, and is heated by the dehumidification component to ensure that the intake air is dry enough under high humidity. The dry gas then passes through the coarse filter component, the fine filter component and the microfilter component in sequence. The coarse filter component initially intercepts large impurities, and the dry gas can prevent them from being blocked. The fine filter component targets small particles, and the microfilter component captures tiny dust. The intake air is pure at multiple levels, and the coarse filter component, the fine filter component and the microfilter component are connected by a docking component to ensure smooth gas flow and system stability. At the same time, during the filtering operation, the cleaning component regularly cleans the outside of the coarse filter component, the fine filter component and the microfilter component to remove impurities, thereby extending the use time. The cleaned impurities slide through the lower row component to the collection component for storage. There is no need to interrupt the filtering throughout the process, which avoids affecting the operating efficiency and lays the foundation for the stable operation and long life of the vacuum pump.

[0012] The present invention is further configured as follows: the coarse filter assembly includes a first card slot, a first right plate, a first left plate and a coarse filter screen, the first card slots are respectively opened on the rear sides of both sides of the filter box, the first right plate is carded inside the first card slot on the right side, the left side of the first right plate is located inside the filter box, the first left plate is carded inside the first card slot on the left side, the right side of the first left plate is located inside the filter box, and the coarse filter screen is fixedly connected to the inside of the first right plate and the first left plate, respectively.

[0013] By adopting the above technical solution, a coarse filter component is set up, and a first card slot is opened on the rear side of both sides of the filter box, and the first right plate and the first left plate with the coarse filter are respectively inserted. When air enters the rear side of the filter box, the coarse filter on the inner side of the first right plate and the first left plate uses the larger mesh and the principle of physical barrier to intercept large-sized fragments and larger-sized impurities in the air first, thereby preventing them from entering the subsequent filtration level, reducing the burden on the subsequent filter, and ensuring the smoothness of the entire filtration process.

[0014] The present invention is further configured as follows: the dehumidification component includes an electric heating tube, an anti-adhesion thermal conductive coating and a thermostat, the electric heating tube is arranged on the rear side of the inside of the filter box, the electric heating tube is located on the front side of the intake pipe, the electric heating tube is located on the rear side of the coarse filter, the anti-adhesion thermal conductive coating is coated on the surface of the electric heating tube, the thermostat is arranged on the left side of the filter box, and the thermostat is electrically connected to the electric heating tube.

[0015] By adopting the above technical solution, a dehumidification component is set up, and the electric heating tube is placed in the filter box and located on the rear side of the coarse filter. When high-humidity air flows through, the electric heating tube is energized and heated, and the heat is evenly transferred through the anti-adhesion thermal conductive coating to increase the air temperature and evaporate the water. The thermostat is electrically connected to the electric heating tube to adjust its power according to the preset temperature range to prevent overheating or insufficient heating, ensure the accurate removal of moisture in the air, avoid impurities adhering to the coarse filter due to moisture condensation, and maintain the good air permeability and filtration performance of the coarse filter.

[0016] The present invention is further configured as follows: the temperature control component includes a temperature sensor, a temperature feedback device and a controller, the temperature sensor is bolted to the left side of the filter box, the sensing end of the temperature sensor is located inside the filter box, the temperature feedback device is bolted to the left side of the filter box, the temperature feedback device is electrically connected to the temperature sensor, the controller is bolted to the left side of the filter box, and the controller is electrically connected to the temperature feedback device and the thermostat respectively.

[0017] By adopting the above technical solution, a temperature control component is set up, and the temperature sensor is bolted to the left side of the filter box. The sensor end penetrates deep inside to sense the air temperature in real time, and transmits the temperature data to the temperature feedback device. The temperature feedback device then transmits the signal to the controller. The controller compares the preset temperature range. When the temperature deviates from the suitable dehumidification range, it immediately sends a command to the thermostat to adjust the heating power of the electric heating tube, realize closed-loop temperature control, ensure stable heating operation of the electric heating tube, and optimize the filtration environment.

[0018] The present invention is further configured as follows: the fine filter assembly includes a second card slot, a second right plate, a second left plate and a fine filter screen, the second card slots are respectively opened in the middle of both sides of the filter box, the second right plate is clamped inside the second card slot on the right side, the left side of the second right plate is located inside the filter box, the second left plate is clamped inside the second card slot on the left side, the right side of the second left plate is located inside the filter box, the fine filter screen is fixedly connected to the inside of the second right plate and the second left plate, respectively, and the fine filter screen is located on the front side of the coarse filter screen.

[0019] By adopting the above technical solution, a fine filter component is set up, and a second slot is set in the middle of both sides of the filter box for the installation of the second right plate and the second left plate connected with the fine filter. The air after coarse filtration by the coarse filter flows forward. The fine filter, with its fine mesh, captures finer dust and some tiny particle impurities in the air based on the dual effects of interception and adsorption, and further purifies the intake air, thereby reducing the pressure on the subsequent microfiltration link and improving the overall filtration accuracy.

[0020] The present invention is further configured as follows: the microfiltration component includes a third card slot, a third right plate, a third left plate and a microfiltration screen, the third card slot is respectively opened on the front sides of both sides of the filter box, the third right plate is clamped inside the third card slot on the right side, the left side of the third right plate is located inside the filter box, the third left plate is clamped inside the third card slot on the left side, the right side of the third left plate is located inside the filter box, the microfiltration screen is fixedly connected to the inside of the third right plate and the third left plate, respectively, and the microfiltration screen is located on the front side of the fine filter screen.

[0021] By adopting the above technical solution, a microfiltration component is set up, and the third right plate and the third left plate with a microfilter are fixed by using the third card slots on the front sides of both sides of the filter box. When the air reaches here, the microfilter uses its extremely small mesh to exert its deep filtration efficiency, and intercepts extremely small particles and possible residual fine pollutants, and then discharges them through the vacuum pump intake pipe, thereby ensuring that the air entering the vacuum pump reaches an extremely high purity standard and meets the strict requirements of precision operations on intake quality.

[0022] The present invention is further configured as follows: the docking assembly includes a left solid block, a right solid block, a magnetic sheet and a magnet sheet, the left solid block is respectively fixedly connected to the top and bottom of the right side of the first left plate, the second left plate and the third left plate, the right solid block is respectively fixedly connected to the top and bottom of the left side of the first right plate, the second right plate and the third right plate, the magnetic sheet and the magnet sheet are respectively bonded to the inner sides of the left solid block and the right solid block, and the magnetic sheet and the magnet sheet are magnetically connected.

[0023] By adopting the above technical solution, a docking assembly is set up, and the left solid block set on the inner side of the first left plate, the second left plate and the third left plate cooperates with the magnetic sheet, so that the magnetic sheet is magnetically connected to the magnet sheet in the right solid block on the left side of the first right plate, the second right plate and the third right plate, so as to ensure that the coarse filter, fine filter and micro filter can be installed conveniently and firmly, facilitate disassembly and maintenance, and ensure that the coarse filter, fine filter and micro filter are tightly fitted during operation to maintain the filtering effect.

[0024] The present invention is further configured as follows: the cleaning brush assembly comprises a motor, a shaft, a front rotating plate, a rear rotating plate, a cleaning brush and a timing starter, the motor is bolted to the front side of the filter box, the output end of the motor passes through the front side of the filter box, the shaft is bolted to the output end of the motor, and the rear side of the shaft passes through the inner sides of the coarse filter, the fine filter and the micro filter in sequence, the front rotating plate is bolted to the front side, the middle and the rear side of the shaft surface respectively, the front rotating plate is respectively located at the front side, the fine filter and the micro filter, the rear rotating plate is bolted to the front side, the middle and the rear side of the shaft surface, the rear rotating plate is respectively located at the rear side of the coarse filter, the fine filter and the micro filter, the cleaning brush is fixedly connected to the inner sides of the front rotating plate and the rear rotating plate respectively, the cleaning brush is respectively located on the outer sides of the coarse filter, the fine filter and the micro filter, the timing starter is bolted to the front side of the filter box, and the timing starter is electrically connected to the motor.

[0025] By adopting the above technical solution, a cleaning brush assembly is set, and the motor is started according to the cycle set by the timing starter. The output end drives the shaft to rotate, and the shaft penetrates the inner side of each layer of filter screen, causing the front rotating plate and the rear rotating plate to rotate accordingly. The cleaning brush fixed thereon is close to the outer side of the coarse filter screen, fine filter screen and micro filter screen. During the rotation, the cleaning brush relies on mechanical friction to sweep away impurities attached to the surface of the coarse filter screen, fine filter screen and micro filter screen to prevent impurities from accumulating and clogging the filter screen, thereby maintaining the air permeability of the coarse filter screen, fine filter screen and micro filter screen, ensuring continuous and efficient filtration, and there is no need to open the filter box to interrupt the air intake process.

[0026] The present invention is further configured as follows: the lower discharge component includes a lower discharge bucket, a smooth coating and an electromagnetic discharge valve, the lower discharge bucket is connected to the bottom of the filter box, the smooth coating is coated on the inside of the lower discharge bucket, and the electromagnetic discharge valve is connected to the bottom of the lower discharge bucket.

[0027] By adopting the above technical solution and setting up a lower discharge component, when the impurities in the coarse filter, fine filter and micro filter are swept into the lower discharge bucket, the smooth coating reduces the friction resistance, allowing the impurities to quickly slide to the bottom electromagnetic discharge valve. The electromagnetic discharge valve opens according to the preset program to discharge the impurities, ensuring that there is no blockage in the lower discharge bucket, providing a smooth waste discharge channel for continuous filtration and cleaning cycles.

[0028] The present invention is further configured as follows: the collection assembly includes an outer shell, a collection box and an anti-adhesion pad, the outer shell is connected to the bottom of the lower discharge bucket, the collection box is slidably connected to the inside of the outer shell, the collection box is located at the bottom of the electromagnetic discharge valve, and the anti-adhesion pad is bonded to the bottom side of the inside of the collection box.

[0029] By adopting the above technical solution, a collection component is set up, and the outer shell is connected to the bottom of the lower discharge bucket to receive and discharge impurities. After the impurities fall, they enter the collection box. During this process, the anti-adhesion pad located in the collection box cushions the impact of the falling impurities and prevents the impurities from adhering to the bottom of the box, making cleaning easier. When the collection box is full, the impurities can be easily drawn out and poured out, and then slid into its original position for continued use, thereby ensuring that the sewage discharge link of the entire filtering and cleaning system is stable and reliable.

[0030] In summary, the present invention has the following beneficial effects:

[0031] 1. By setting up a filtering mechanism, when the gas enters the filter box from the suction pipe, the gas first passes through the dehumidification component, which evaporates the moisture in the gas by heating. Even in a high humidity environment, it can ensure that the incoming air dryness meets the standard. The dried gas passes through the coarse filter component, which initially intercepts the larger impurities in the air, and the dried gas can avoid the adhesion of impurities and clogging of the coarse filter component. At the same time, the temperature control component monitors and controls the temperature in the filter box in real time to create the best working conditions for the dehumidification component and ensure its stable and efficient operation. Then, the gas comes to the fine filter component and the micro filter component area. The fine filter component further filters smaller particles, and the micro filter component captures those extremely tiny dust and particles with a more sophisticated structure. Multi-level fine filtration ensures that the gas entering the vacuum pump intake pipe is extremely pure. Moreover, the coarse filter component, the fine filter component and the micro filter component are closely connected through the docking component, which not only ensures the smooth flow of gas, but also maintains the stability of the entire filtration system.

[0032] 2. By setting up a cleaning mechanism, during long-term operation, the cleaning component can regularly clean the outside of the coarse filter component, fine filter component and microfiltration component without opening the filter box, and remove the attached impurities in time to keep it always in good filtering performance, greatly extending the filtering time. The impurities brushed off will slide down to the collection component through the lower row component for unified storage. The whole process does not require interruption of the filtering operation, avoiding the impact of frequent opening and cleaning on the operating efficiency, allowing the vacuum pump intake filtration to be carried out continuously and efficiently, laying a solid foundation for the stable operation and long life of the vacuum pump.

[0054] Brief description of the use process: First, after the gas enters the filter box 1 from the intake pipe 2, it first contacts the electric heating tube 401a. In this component, the electric heating tube 401a heats and evaporates the moisture in the high-humidity air with the help of the anti-adhesion thermal conductive coating 401b. The thermostat 401c accurately controls the temperature to ensure that the intake air is dry and prevents impurities from adhering to the coarse filter 403d due to moisture. The coarse filter 403d is located at the rear side of the filter box 1. The first left plate 403c and the first right plate 403b with the coarse filter 403d are inserted through the first card slot 403a. The coarse filter 403d intercepts large-sized impurities with its larger mesh to reduce the subsequent filtering pressure. In this process, the temperature sensor 402a monitors the temperature in the filter box 1 in real time, and then feeds back to the temperature feedback device 402b and then transmits it to the controller 402c. The controller 402c adjusts and controls the thermostat 401c of the electric heating tube 401a, thereby ensuring the stable operation of the electric heating tube 401a. Subsequently, the air The air flows to the fine filter 404d in the middle. The fine filter 404d intercepts and absorbs fine dust with its fine mesh to achieve further purification. Then it passes through the micro filter 405d. The micro filter 405d uses extremely small meshes to deeply filter extremely small particles. The extremely high-purity gas enters the vacuum pump intake pipe 3 and is transported to its vacuum pump. In addition, the left fixed block 406a provided on the inner side of the first left plate 403c, the second left plate 404c and the third left plate 405c cooperates with the magnetic The magnetic sheet 406c is magnetically connected to the magnet sheet 406d in the right solid block 406b on the left side of the first right plate 403b, the second right plate 404b and the third right plate 405b, so as to ensure that the coarse filter 403d, the fine filter 404d and the micro filter 405d can be installed conveniently and firmly, facilitate disassembly and maintenance, and ensure that the coarse filter 403d, the fine filter 404d and the micro filter 405d are tightly fitted during operation to maintain the filtering effect.

[0055] Embodiment 2:

[0056] refer to Figure 9-11 , a vacuum pump air intake filter mechanism that can effectively filter impurities includes a cleaning mechanism 5, the cleaning mechanism 5 includes a cleaning brush component 501, a lower row component 502 and a collecting component 503, the cleaning brush group is arranged inside the filter box 1, the cleaning brush component 501 is respectively located on the outside of the coarse filter component 403, the fine filter component 404 and the micro filter component 405, the lower row component 502 is connected to the bottom of the filter box 1, and the collecting component 503 is arranged at the bottom of the lower row component 502. By setting the cleaning mechanism 5, during the filtering operation, the cleaning brush component 501 regularly cleans the outside of the coarse filter component 403, the fine filter component 404 and the micro filter component 405 to peel off impurities, thereby extending the service life, and the cleaned impurities slide through the lower row component 502 to the collecting component 503 for storage, without interrupting the filtering throughout the process, avoiding affecting the working efficiency, and laying a foundation for the stable operation and long life of the vacuum pump.

[0057] like Fig. 9 As shown, the cleaning brush assembly 501 includes a motor 501a, a shaft 501b, a front rotating plate 501c, a rear rotating plate 501d, a cleaning brush 501e and a timing starter 501f. The motor 501a is bolted to the front side of the filter box 1, and the output end of the motor 501a passes through the front side of the filter box 1. The shaft 501b is bolted to the output end of the motor 501a, and the rear side of the shaft 501b passes through the inner sides of the coarse filter 403d, the fine filter 404d and the micro filter 405d in sequence. The front rotating plate 501 c are bolted to the front side, middle and rear side of the shaft rod 501b, respectively; the front rotating plate 501c is located at the front side of the coarse filter 403d, the fine filter 404d and the micro filter 405d, respectively; the rear rotating plate 501d is bolted to the front side, middle and rear side of the shaft rod 501b, respectively; the rear rotating plate 501d is located at the rear side of the coarse filter 403d, the fine filter 404d and the micro filter 405d, respectively; the cleaning brush 501e is fixedly connected to the inner side of the front rotating plate 501c and the rear rotating plate 501d, respectively; The brushes 501e are respectively located on the outside of the coarse filter 403d, the fine filter 404d and the micro filter 405d, and the timing starter 501f is bolted to the front side of the filter box 1. The timing starter 501f is electrically connected to the motor 501a. By setting the cleaning brush component 501, the motor 501a is started according to the set cycle of the timing starter 501f, and the output end drives the shaft 501b to rotate. The shaft 501b penetrates the inner side of each layer of the filter, so that the front rotating plate 501c and the rear rotating plate 501d rotate accordingly, The cleaning brush 501e fixed thereon is closely attached to the outer sides of the coarse filter 403d, the fine filter 404d and the micro filter 405d. When the cleaning brush 501e is rotating, it relies on mechanical friction to sweep away the impurities attached to the surfaces of the coarse filter 403d, the fine filter 404d and the micro filter 405d to prevent the impurities from accumulating and clogging the filter, thereby maintaining the air permeability of the coarse filter 403d, the fine filter 404d and the micro filter 405d, ensuring continuous and efficient filtration without opening the filter box 1 to interrupt the air intake process.

[0058] like Fig.10 As shown, the lower row component 502 includes a lower row bucket 502a, a smooth coating 502b and an electromagnetic drain valve 502c.

By setting the lower row component 502, when the impurities of the coarse filter 403d, the fine filter 404d and the micro filter 405d are swept into the lower row bucket 502a, the smooth coating 502b reduces the friction resistance, so that the impurities quickly slide to the bottom electromagnetic drain valve 502c, and the electromagnetic drain valve 502c opens according to the preset program to discharge the impurities, ensuring that there is no blockage in the lower row bucket 502a, providing a smooth waste discharge channel for continuous filtering and cleaning cycles.

[0059] like Fig.11As shown, the collecting component 503 includes an outer shell 503a, a collecting box 503b and an anti-adhesion pad 503c.

The collecting box 503b is located at the bottom of the electromagnetic discharge valve 502c, and the anti-adhesion pad 503c is bonded to the bottom side of the collecting box 503b. By setting the collecting component 503, the outer shell 503a is connected to the bottom of the lower discharge bucket 502a to receive and discharge impurities, and the impurities fall into the collecting box 503b. During this process, the anti-adhesion pad 503c located in the collecting box 503b buffers the impact of the impurities falling, and prevents the impurities from adhering to the bottom of the box, which is convenient for cleaning. When the collecting box 503b is full, the impurities can be easily drawn out and poured out, and then slid into the original position for continued use, thereby ensuring that the sewage discharge link of the entire filtering and cleaning system is stable and reliable.

[0060] Brief description of the use process: First, during the long-term filtering operation, the motor 501a is started according to the cycle set by the timer starter 501f, and the output end drives the shaft 501b to rotate. The shaft 501b penetrates the inner side of each layer of the filter screen, so that the front rotating plate 501c and the rear rotating plate 501d rotate accordingly, and the cleaning brush 501e fixed thereon is close to the outer side of the coarse filter screen 403d, the fine filter screen 404d and the micro filter screen 405d. The cleaning brush 501e is rotating, and the impurities attached to the surface of the coarse filter screen 403d, the fine filter screen 404d and the micro filter screen 405d are swept away by mechanical friction. The impurities fall to prevent accumulation and clogging of the filter screen, and then after the separated impurities fall into the lower discharge bucket 502a, the smooth coating 502b reduces the friction resistance, so that the impurities quickly slide to the bottom electromagnetic discharge valve 502c, and the electromagnetic discharge valve 502c opens according to a preset program to discharge the impurities into the collection box 503b inside the shell 503a. During this process, the anti-adhesion pad 503c located in the collection box 503b cushions the impact of the impurities falling, and prevents the impurities from adhering to the bottom of the box, making it easy to clean. When the collection box 503b is full, the impurities can be easily drawn out and poured out, and then slid into the original position for continued use.
